Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bracket equipment, and in particular relates to a plastic film buffer bracket. Background Art
[0002] In the process of plastic film production and processing, a punching machine is needed to punch holes in the plastic film. The plastic film is fed into the feed end of the punching machine, then punched, and output through the discharge end of the punching machine, and finally wound on a roller. In the process of punching with an existing punching machine, the plastic film is easily affected by external forces. For example, when the power voltage is unstable, the speed of the roller suddenly changes, or foreign objects suddenly fall on the surface of the plastic film, affecting the moving speed of the plastic film and thus affecting the punching effect. At the same time, when the plastic film is suddenly subjected to external forces, without buffering, the surface of the plastic film is subjected to tension, which can easily damage the plastic film.

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0022] See also Figure 1-4 As shown, an embodiment of the utility model is a plastic film buffer bracket, comprising two brackets 10 arranged symmetrically to each other, wherein one bracket 10 is placed at the feed end of the punching machine, and the other bracket 10 is placed at the discharge end of the punching machine, to guide the plastic film; a guide roller 20 is movably mounted on each bracket 10, and during use, the plastic film passes through the guide roller 20, and when the plastic film is subjected to external force, the guide roller 20 can buffer the plastic film to prevent the plastic film from being damaged due to excessive surface tension of the plastic film.
[0023] The bracket 10 includes a support plate 15 installed at both ends of the guide roller 20, and the support plate 15 is respectively provided with a first mounting hole 11, a second mounting hole 12 and a third mounting hole 13, and a slider 30 is slidably installed inside the first mounting hole 11, the second mounting hole 12 and the third mounting hole 13. Specifically, the slider 30 includes a first slider 31 installed in the first mounting hole 11, a second slider 32 and a third slider 33 installed in the second mounting hole 12, and a fourth slider 34 installed in the third mounting hole 13.
[0024] The first mounting hole 11 is provided with first limiting strips 111 on both sides of the interior along the vertical direction, and limiting grooves are provided on both sides of the first slider 31, so that the first slider 31 can move in the vertical direction; the first mounting hole 11 is provided with a spring, the upper end of the spring is connected to the first slider 31, and the lower end of the spring is connected to the bottom wall of the first mounting hole 11, and the first slider 31 has a buffering function through the provided spring. The second mounting hole 12 is provided with second limiting strips 121 on both sides of the upper and lower sides, and limiting grooves are provided on both sides of the upper and lower sides of the second slider 32 and the upper and lower sides of the third slider 33, so that the second slider 32 and the third slider 33 can move in the horizontal direction, wherein a spring is provided between the second slider 32 and the third slider 33, one end of the spring is connected to the second slider 32, and the other end of the spring is connected to the third slider 33. The third mounting hole 13 is provided with third limit strips 131 on the left and right sides along the vertical direction, and the third slider 33 is provided with limit grooves on both sides thereof, so that the fourth slider 34 can move in the third mounting hole 13 along the vertical direction. A spring is provided in the third mounting hole 13, and the upper end of the spring is connected to the top wall of the third mounting hole 13, and the lower end of the spring is connected to the fourth slider 34.
[0025] The guide roller 20 includes a first guide roller 21 connected between two first sliders 31, a second guide roller 22 connected between two second sliders 32, a third guide roller 23 connected between two third sliders 33, and a fourth guide roller 24 connected between two fourth sliders 34. The bracket 10 is threadedly connected with a first screw rod, one end of which contacts the second slider 32. By rotating the screw rod, the distance between the second slider 32 and the third slider 33 can be adjusted, and the distance between the second guide roller 22 and the third guide roller 23 can be further adjusted, thereby adjusting the tension of the second guide roller 22 and the third guide roller 23 on the plastic film, which is suitable for films of different thicknesses and different types. A second screw rod 14 is arranged on the top of the bracket 10, and the lower end of the second screw rod 14 contacts the first slider 31. The preload force of the spring on the first guide roller 21 is adjusted by the second screw rod 14, thereby adjusting the tension of the film, and further adjusting the tension that can move the first guide roller 21 downward. It should be noted that when the external force acting on the surface of the film is small, the film cannot press down the first guide roller 21, so that the first guide roller 21 remains stationary. When the external force acting on the surface of the film is large, the film presses down the first guide roller 21, so that the first guide roller 21 moves downward, and the first guide roller 21 has a buffering effect on the film.
[0026] In this specific embodiment, during use, the plastic film is first passed through the middle position of the second guide roller 22 and the third guide roller 23, then wound downward through the top of the first guide roller 21, and then passed through the bottom of the fourth guide roller 24, enters the feed end of the puncher for punching, and then passes through another bracket 10. The passing method is that it first passes through the bottom of the fourth guide roller 24, then winds downward through the top of the first guide roller 21, and passes through the middle position of the second guide roller 22 and the third guide roller 23; the second guide rollers 22 and the third guide rollers 23 on the two brackets 10 keep the two ends of the plastic film in a tensioned state, so that the puncher can smoothly punch holes in the plastic film. When the plastic film is subjected to external force, under the action of the first guide roller 21, the fourth guide roller 24 and the corresponding spring, a good buffering effect is played on the plastic film to avoid damage to the plastic film.
