Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic clamps, in particular to a pneumatic clamp structure for a packaging machine. Background Art

[0002] In the packaging process of polyoxymethylene products, packaging machines are often used for packaging operations. The packaging machines use pneumatic clamping to achieve the fixing operation of the packaging bags.

[0003] Among them, the pneumatic clamp structure of the packaging machine includes a pneumatic pipeline, a booster valve arranged on the pneumatic pipeline, a cylinder assembly connected to the pneumatic pipeline, and a clamping plate arranged on the cylinder assembly. This structure has the following disadvantages during implementation:

[0004] 1. When the pressure in the booster valve at the pneumatic line fluctuates and causes unstable air pressure, the pressure provided by the cylinder assembly is insufficient to fix the 25kg packaging bag;

[0005] 2. The clamping plate is made of aluminum alloy, which has poor anti-slip effect and is severely worn during long-term use, which will affect the packaging effect and often cause the packaging bag to break or wrinkles at the seal during the packaging process. Utility Model Content

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A pneumatic clamp structure for a packaging machine includes a pneumatic pipeline, a pressure-boosting valve arranged on the pneumatic pipeline, a cylinder assembly connected to the pneumatic pipeline, and a clamping plate arranged on the cylinder assembly;

[0009] It also includes a buffer tank; the buffer tank is installed on the pneumatic pipeline and is placed between the booster valve and the cylinder assembly to stabilize the air pressure output from the pneumatic pipeline to the cylinder assembly;

[0010] It also includes an anti-skid sheet; the anti-skid sheet is arranged on the surface of the clamping plate, and the surface of the anti-skid sheet is provided with anti-skid lines.

[0011] Furthermore, the anti-slip sheet is made of wear-resistant stainless steel.

[0012] Furthermore, the length and width of the anti-slip sheet are adapted to the length and width of the clamping plate.

[0013] Furthermore, the back side of the anti-slip sheet is adhered to the surface of the clamping plate by bonding so that the two are detachable.

[0014] Furthermore, the anti-slip pattern is composed of a plurality of spikes.

[0015] Furthermore, the number of spikes per unit area on the surface of the anti-slip sheet is increased so that the distance between two adjacent spikes does not exceed 0.01 mm.

[0016] Furthermore, the angle of the spikes on the surface of the anti-slip sheet is 40-80 degrees.

[0017] Furthermore, the buffer tank is a direct contact buffer tank or a diaphragm buffer tank.
