DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figures 1 to 6 As shown, the utility model provides a punching device based on plastic bag processing, including a base 1, a support plate 2 is fixedly installed above the front end of the base 1, a top plate 3 is fixedly installed above the support plate 2, a cylinder 4 is fixedly installed above the top plate 3, a telescopic rod 5 extending to the bottom of the top plate 3 is fixedly installed below the cylinder 4, a circular shaft 6 is fixedly installed below the telescopic rod 5, a connecting shaft 9 is movably installed inside the circular shaft 6, a circular plate 12 is fixedly installed below the connecting shaft 9, a mounting seat 13 is fixedly installed below the circular plate 12, a punching blade 14 is fixedly installed below the mounting seat 13, an outer ring block 15 located outside the mounting seat 13 is fixedly installed below the circular plate 12, a first circular groove 16 is opened inside the outer ring block 15, a limiting block 17 is movably installed inside the first circular groove 16, and a fixed circular ring 18 extending to the bottom of the outer ring block 15 is fixedly installed below the limiting block 17.
[0025] A plastic bag is placed on top of the base 1, and then the cylinder 4 is started, so that the cylinder 4 drives the telescopic rod 5 to move downward, the telescopic rod 5 drives the circular shaft 6 to move downward, the circular shaft 6 drives the circular groove 7 to move downward, the circular groove 7 drives the circular plate 12 to move downward, and the circular plate 12 drives the fixed circular ring 18 and the punching blade 14 to move downward. When the fixed circular ring 18 contacts the plastic bag, it moves inward, so that the fixed circular ring 18 fixes the plastic bag, and then the punching blade 14 punches holes in it.
[0026] By starting the cylinder 4, the cylinder 4 drives the circular plate 12 to move downward, and the circular plate 12 drives the fixed ring 18 and the punching blade 14 to move downward. When the fixed ring 18 contacts the plastic bag, the fixed ring 18 shrinks to the inside of the first circular groove 16, and the plastic bag is fixed by elastic deformation through the reset spring 19, thereby punching. Compared with the traditional punching device for plastic bag processing, the punching device for plastic bag processing fixes the plastic bag with the fixed ring 18 and then punches, thereby preventing the deformation of the plastic bag from affecting the processing.
[0027] A rectangular groove 21 is formed on the surface of the base 1 , a round rod 22 is fixedly installed inside the rectangular groove 21 , a movable block 23 is movably sleeved outside the round rod 22 , and a rectangular plate 24 is fixedly installed above the movable block 23 .
[0028] When it is necessary to clean the waste above the base 1, it is only necessary to pull the rectangular plate 24 downward to make the rectangular plate 24 move downward. The rectangular plate 24 drives the movable block 23 to move downward inside the rectangular groove 21. The movable block 23 moves downward around the round rod 22 to squeeze the reset spring 25, causing the reset spring 25 to deform, thereby cleaning the waste above the base 1 through the rectangular plate 24. After letting go, the reset spring 25 releases its elastic potential energy to drive the rectangular plate 24 back to its original position.
[0029] By pulling the rectangular plate 24 downward, the rectangular plate 24 moves on the surface of the base 1 to clean the top of the base 1. Compared with the traditional punching device for plastic bag processing, this punching device for plastic bag processing cleans the waste by pulling the rectangular plate 24, thereby preventing the punching waste from sticking to the plastic bag and affecting the processing.
[0030] A circular groove 7 is formed inside the circular shaft 6 , and a connecting shaft 9 is movably installed inside the circular groove 7 .
[0031] The circular shaft 6 moves downward, driving the connecting shaft 9 to move downward, thereby driving the circular plate 12 to move downward.
[0032] The outer surface of the connecting shaft 9 is provided with an arc groove 10 , and the inside of the circular groove 7 is fixedly installed with a short block 8 located inside the arc groove 10 .
[0033] After the punching blade 14 contacts the plastic bag, the circular shaft 6 moves downward to drive the short block 8 to slide inside the arc groove 10, driving the connecting shaft 9 to rotate, thereby driving the punching blade 14 to rotate and cut the plastic bag.
[0034] A telescopic spring 11 is elastically mounted at the bottom of the circular groove 7 , and the telescopic spring 11 is located above the connecting shaft 9 .
[0035] The circular shaft 6 moves downward, driving the connecting shaft 9 to move downward. After the punching blade 14 contacts the plastic bag, the circular shaft 6 moves downward to squeeze the telescopic spring 11, causing the telescopic spring 11 to deform.
[0036] A return spring 19 is elastically installed on the inner side of the first annular groove 16 , and the return spring 19 is located above the limit block 17 .
[0037] After the fixing ring 18 contacts the plastic bag, it shrinks to the inside of the first annular groove 16, and squeezes the return spring 19, so that the return spring 19 is deformed.
[0038] A second annular groove 20 is formed on the surface of the base 1 , and the second annular groove 20 corresponds to the punching blade 14 .
[0039] By providing the second annular groove 20 on the surface of the base 1 , the punching blade 14 can better punch holes in the plastic bag.
[0040] A second return spring 25 is elastically installed between the inner side of the rectangular groove 21 and the inner side of the movable block 23 , and the second return spring 25 is movably connected to the outer side of the round rod 22 .
[0041] The movable block 23 moves downward around the round rod 22 to squeeze the reset spring 25, causing the reset spring 25 to deform, thereby cleaning the waste above the base 1 through the rectangular plate 24. After letting go, the reset spring 25 releases its elastic potential energy to drive the rectangular plate 24 back to its original position.
[0042] The working principle and use process of this utility model:
[0043] A plastic bag is placed on top of the base 1, and then the cylinder 4 is started, so that the cylinder 4 drives the telescopic rod 5 to move downward, the telescopic rod 5 drives the circular shaft 6 to move downward, the circular shaft 6 drives the circular groove 7 to move downward, the circular groove 7 drives the circular plate 12 to move downward, and the circular plate 12 drives the fixed circular ring 18 and the punching blade 14 to move downward. When the fixed circular ring 18 contacts the plastic bag, it moves inward, so that the fixed circular ring 18 fixes the plastic bag, and then the punching blade 14 punches holes in it.
[0044] When it is necessary to clean the waste above the base 1, it is only necessary to pull the rectangular plate 24 downward to make the rectangular plate 24 move downward. The rectangular plate 24 drives the movable block 23 to move downward inside the rectangular groove 21. The movable block 23 moves downward around the round rod 22 to squeeze the reset spring 25, causing the reset spring 25 to deform, thereby cleaning the waste above the base 1 through the rectangular plate 24. After letting go, the reset spring 25 releases its elastic potential energy to drive the rectangular plate 24 back to its original position.
