Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a PE heat shrink film production and processing cutting machine. Background Art

[0002] PE heat shrink film production, processing and cutting machine is a kind of equipment specially used for processing and cutting PE (polyethylene) heat shrink film. PE heat shrink film is a material widely used in the packaging industry. It has excellent shrinkage and protection properties and can effectively fix and protect the packaged items.

[0003] The existing PE heat shrink film production and processing cutting machines generally lack the function of effectively fixing the film material during the cutting process. The PE heat shrink film is prone to displacement or sliding during the cutting process, resulting in inaccurate cutting position, which seriously affects the product quality. This instability not only increases the scrap rate, but also reduces production efficiency, bringing additional cost burden to manufacturers. Therefore, we propose a PE heat shrink film production and processing cutting machine. Utility Model Content

[0015] The cylinder 3 is fixedly connected to a piston rod through the output end at the bottom thereof, and the lower end of the piston rod penetrates into the interior of the shell 1 and is fixedly connected to the center of the top of the lifting box 2, so that the lifting box 2 is driven to perform lifting motion by the cylinder 3.

[0016] The lower ends of the four connecting rods 6 arranged on both sides pass through the outside of the lifting box 2 and are fixedly connected to the tops of the two pressing plates 7 respectively. The connecting rods 6 push the pressing plates 7 to press the membrane material.

[0017] The two wedge-shaped blocks 8 are in contact with the inclined surfaces provided at the lower ends of the two moving blocks 10 through the inclined surfaces provided at the upper ends thereof. When the wedge-shaped blocks 8 move upward, the moving blocks 10 can be pressed to move horizontally through the contact between the inclined surfaces.

[0018] Slide rods 11 are fixedly installed at the front end and the rear end of the top of the lifting box 2, and sliding sleeves 12 are slidably connected to the two side positions of the surfaces of the two front and rear slide rods 11. The lower ends of the four sliding sleeves 12 are respectively fixedly connected to the tops of the two moving blocks 10, which has a stabilizing effect on the moving blocks 10 during horizontal movement.

[0019] First slide rails 13 are fixedly installed at the bottom positions on both sides of the lifting box 2, first sliders 14 are fixedly installed at both ends of the cross plate 5, the opposite ends of the two first sliders 14 extend to the inside of the two first slide rails 13 and are slidably connected to the inner walls of the first slide rails 13, second slide rails 15 are fixedly installed at the top positions on both sides of the shell 1, second sliders 16 are fixedly installed at the center of both sides of the lifting box 2, the opposite ends of the two second sliders 16 extend to the inside of the two second slide rails 15 and are slidably connected to the inner walls of the second slide rails 15, which play a role in stabilizing and limiting the lifting box 2 and the cross plate 5 when they move vertically.

[0020] An observation window is fixedly installed on the front surface of the shell 1, and a film inlet 17 and a film outlet 18 are respectively opened at the bottom of both sides of the shell 1. Guide rollers 19 are fixedly installed at the upper and lower ends of the outer wall of the shell 1 corresponding to the film inlet 17 and the film outlet 18 respectively. The film material enters through the film inlet 17 and is sent out through the film outlet 18 after cutting. The guide rollers 19 can guide the film material during the transportation through the conveying device to ensure the stability of the film material during transportation.

[0021] Working principle: The PE heat shrink film is conveyed by the conveying device. When the film material enters the shell 1 through the film inlet 17, the control cylinder 3 drives the lifting box 2 to move downward. When the lifting box 2 moves downward, since the height of the pressure plate 7 is lower than the cutting tool 4, the two pressure plates 7 will contact and press the film material first. At this time, the cylinder 3 continues to work, and the cutting tool 4 continues to move downward and cuts the film material pressed on the cutting seat 20. During the cutting process, the four connecting rods 6 drive the two wedge blocks 8 on the cross plate 5 to move upward, and the inclined surfaces on the two wedge blocks 8 respectively contact the inclined surfaces at the lower ends of the two moving blocks 10. The two moving blocks 10 are subjected to force and move relatively at the same time and compress the two springs 9. Due to the existence of the spring 9, the cutting tool 4 will not be affected from continuing to move downward when the film material is pressed.

[0022] To sum up: the PE heat shrink film production and processing cutting machine, through the design of the lifting box 2, cross plate 5, connecting rod 6, pressure plate 7, wedge block 8, spring 9 and moving block 10, when the cylinder 3 drives the lifting box 2 to drive the cutting tool 4 at the bottom to move downward, the pressure plates 7 on both sides will first contact the film material and press the film material, the lifting box 2 continues to move downward, the four connecting rods 6 push the two wedge blocks 8 on the cross plate 5 to press the two moving blocks 10, so that the two moving blocks 10 move relative to each other and compress the spring 9, the cutting tool 4 will continue to move downward and cut the film material, so that the cutting machine can fix the film material during the cutting process, effectively preventing the displacement or sliding of the film material, which will greatly improve the accuracy and precision of cutting, reduce the scrap rate, and improve product quality.
