What are the main parts of small vacuum machines?
Aluminum Alloy ordinary aluminum alloy and magnesium alloy, the acid and alkali resistance, corrosion resistance, but the cost is higher, Aluminum Alloy vacuum chamber through a milling processing, the sealing surface and sealing groove is very smooth, the vacuum chamber has good sealing performance. The commonly used stainless steel plate thickness is 2-4MM, thickness of vacuum compression of easy deformation caused by weld cracking, leakage of vacuum chamber, in addition, the general on stainless steel vacuum chamber is provided with a seal groove around the plane, because of the effect of processing, the sealing groove is less smooth, vacuum sealing performance is reduced accordingly. Therefore, some models of vacuum chamber with Aluminum Alloy casting after milling under vacuum sealing groove, chamber adopts thick stainless steel plate processing into plate type, the director, make it short. When purchasing, packaging, and other solid particles relatively dry and non corrosive materials, can be used Aluminum Alloy material, and packaging with soup, salt, acid composition of higher material, can use stainless steel or aluminum magnesium alloy material. The sealing ring is generally made of silicone rubber, black rubber, a few low-grade products using foam rubber, silicone rubber, high temperature resistance, corrosion resistance, good sealing performance, long service life, the foaming rubber sealing is poor, easy to fall off, and short service life.

The composition of the vacuum pump: vacuum pump, motor, vacuum chamber, sealing strip, plexiglass plate, upper cover, air bag, solenoid valve, etc..1, the upper and lower vacuum chamber and the sealing ringAt present, usually called vacuum machines are cavity structure, from the upper vacuum chamber, the lower vacuum chamber and placed in the upper and lower vacuum chamber between the sealing ring. The upper and lower vacuum chambers are generally made of aluminium alloy, which are machined by milling or stainless steel sheets, welded and machined by flanging or moulding. There are also two upper and lower vacuum chambers which are made of aluminum alloy and stainless steel
Hot pressing device and printing deviceThe device is installed in the vacuum chamber, there are usually two groups, a group of single room tipping activities arranged on the lower part of the vacuum chamber and double chamber reciprocating movable part is arranged on the upper part of the vacuum chamber, active device mainly consists of the following parts, heat sealing chamber is fixed on the upper vacuum box room two, head guide column and a spring reset device, hot press frame seat two head guide sleeve is sheathed on the guide pillar, heat sealing between the gas chamber and hot box frame seat is provided with a heat sealing chamber (also known as atmospheric vacuum chamber, said heat sealing chamber for small room heat) sealed air chamber is provided with plastic pipes, two head with a pinch clamp, rubber adhesive processing water is also useful a bicycle or a manpower vehicle tyre, the middle has a gas nozzle, hot pressing frame body with epoxy boards fixed pressing frame seat, two head belt rolling shaft, the winding shaft roll of Ni Cr alloy belt Tight positioning, covered with heat sealing cloth. The fixed part device mainly printing tape and tape box printing, printing glue used in silicone rubber processing, a plane with twill or straight lines, the other side is provided with a round or square hole, the silicon rubber used for processing of words or characters embedded in the park, in the seal and printed on the concave transparent production date. If need is needed in the color printing, printer ribbon. Small treasure vacuum machine
On the vacuum chamber, opening displacement and balancing deviceThe commonly used vacuum machine has a single room and double room two, single room for tipping, two stents in the upper and lower vacuum chamber with a middle rear, wearing a double torsion spring axis by double torsion spring force balance, the opening angle of 45-75 degrees ranging. Double chamber for reciprocating, vacuum chamber is divided into two studios, vacuum chamber comprises four connecting rod support about displacement, the four connecting rods is fixed on the two axis, the long axis of a spring fork, two tension springs located in the lower frame, the upper part of the positioning in the spring fork, to balance the operation of gravity, two axis by two sets of bearing positioning, four upper connecting rods with miniature bearings, so the displacement is very easy, starting with vacuum pressure, back after gas can automatically open. The four connecting rods on the support displacement of the vacuum chamber, before and after each axis on the two, must be kept parallel to about two sets of connecting rods must remain relatively parallel, to ensure that the vacuum chamber remain parallel in about any position under the same vacuum chamber or cause the upper and lower vacuum chamber can't keep parallel, then the operation pressure increased significantly, even can not establish normal vacuum.
