Description

Technical Field

[0001] This utility model relates to the field of garbage can processing technology, and in particular to a punching device for garbage cans. Background Technology

[0002] A trash can, also known as a waste bin or garbage can, is a container for holding garbage. Most are made of metal or plastic. When in use, a plastic bag is placed inside, and when there is too much garbage, the bag can be tied up and thrown away. During the manufacturing process of trash cans, openings need to be made, such as mounting holes, heat dissipation holes, ventilation holes, etc. Trash cans are usually made by punching holes during manufacturing.

[0003] Chinese utility model patent CN214022933U discloses a punching device for processing trash cans, including a base, a support plate, a first cylinder, a clamp, a punching head, and a grinding device. The support plate is welded to one end of the upper surface of the base. The first cylinder is fixed to the inner side of the top of the support plate. The clamp is fixed to the extended end of the first cylinder. The punching head is fixed to the clamp. A crossbeam is welded to the top of the support plate. A second cylinder is fixed to the bottom of the crossbeam. A hanging plate is fixed to the extended end of the second cylinder. An extrusion plate and a hanging frame are fixed to the two ends of the bottom of the hanging plate, respectively. A motor is fixed to the bottom of the hanging frame. A grinding disc is fitted on the output shaft of the motor. This utility model can complete punching and grinding in one operation, eliminating the process of transporting and grinding the trash can. At the same time, the extrusion plate squeezes the sides of the trash can to prevent deformation of the sides of the trash can during punching, thereby strengthening the stability of the trash can.

[0004] However, the polishing disc can only polish the burrs on the outside of the trash can holes, and it cannot polish the burrs inside the holes. Some burrs will remain inside the holes, resulting in poor polishing effect. Utility Model Content

[0005] The purpose of this invention is to provide a punching device for trash cans, which can improve the grinding effect of trash can holes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punching device for a trash can, comprising a base and a support plate disposed thereon, a crossbeam disposed at the upper end of the support plate, a cylinder one disposed on one side of the support plate, a punching head disposed at the top end of the piston rod of the cylinder one, a cylinder two disposed on the side of the crossbeam facing the base, a motor one disposed at the top end of the piston rod of the cylinder two, a grinding disc disposed on the output shaft of the motor one, a connecting plate disposed at the top end of the piston rod of the cylinder two, a support plate disposed on the side of the connecting plate away from the cylinder two, a placement plate rotatably disposed at one end of the support plate, the motor one placed on the placement plate, and a motor two disposed at the end of the placement plate opposite to the motor one, a limiting block sleeved on the output shaft of the motor two, a support cylinder slidably disposed on the outer wall of the limiting block, a grinding rod disposed at the end of the support cylinder away from the motor two, a vertical plate disposed on the placement plate, an internal thread disposed on the vertical plate, and an external thread disposed on the outer wall of the support cylinder that is screwed into the internal thread.

[0012] The beneficial effects of this utility model are as follows: A connecting plate is driven by cylinder two, a support plate is mounted on the connecting plate, and a placement plate is rotatably mounted on the support plate. Motor one and motor two are positioned opposite each other on the placement plate. A grinding disc is mounted on the output shaft of motor one, and a grinding rod is indirectly connected to the output shaft of motor two. The grinding rod extends into the punched hole of the trash can for grinding. Compared with the prior art, this utility model connects a limiting block to the output shaft of motor two, and a support cylinder is slidably mounted on the outer wall of the limiting block. The support cylinder connects to the grinding rod, and a vertical plate is mounted on the placement plate with an internal thread. The outer wall of the support cylinder is connected to the internal thread. The threaded external thread, when driven by the motor, allows the grinding rod to rotate and move back and forth simultaneously, achieving grinding of the holes in the trash can. This improves the grinding effect on the punched holes in the trash can and avoids excessive burrs inside the holes, which could affect subsequent user use. At the same time, an air jet head connected to an air pump is installed on the upright plate to blow away the metal debris and dust generated during grinding, preventing them from accumulating inside the holes and affecting the grinding effect or clogging the grinding rod. The air blowing also has a certain cooling effect, preventing overheating and damage to the trash can or the grinding rod. Attached Figure Description

A drive motor 19 is arranged on the upper side of the support plate 31 away from the connecting plate 30. A placement plate 9 is arranged on the lower side of the support plate 31 away from the connecting plate 30. In this utility model, the placement plate 9 is I-shaped. A rotating rod 17 is arranged at its upper end and rotatably connected to the placement plate 9. A driven wheel 18 is sleeved on the outer wall of the rotating rod 17. A driving wheel 20 that meshes with the driven wheel 18 is sleeved on the output shaft of the drive motor 19.

[0025] Motor 7 and Motor 10 are fixedly mounted on the placement plate 9, respectively, with the output shaft of Motor 7 equipped with a grinding disc 8. A limiting block 11 is fitted onto the output shaft of Motor 10. A support cylinder 12 is slidably mounted on the outer wall of the limiting block 11. A guide strip 21 is provided along the length of the outer wall of the limiting block 11. A guide groove 22 is provided on the inner wall of the sliding end of the support cylinder 12 that is slidably connected to the guide strip 21. A vertical plate 14 is vertically mounted on the upper side of the placement plate 9. An internal thread 15 is provided in the middle of the vertical plate 14.

[0027] After the trash can is placed on the base 1 and the holes are drilled, the extension and retraction of cylinder 25 drives motor 17 to move to the appropriate height. Motor 17 starts rotating forward to polish the burrs on the surface of the holes in the trash can. After polishing, cylinder 25 retracts, positioning the placement plate 9 above the trash can. Then, motor 19 starts rotating forward, driving the driven wheel 18 through the drive wheel 20. The driven wheel 18, through the rotating rod 17, drives the placement plate 9 to rotate 180 degrees around the central axis of the rotating rod 17, causing motor 20 to rotate to the original position of motor 17. The cylinder 25 extends and moves downward, aligning the grinding rod 13 with the hole in the trash can. Then, the motor 210 is started. The motor 210 drives the support cylinder 12 to rotate through the limit block 11. During the rotation of the support cylinder 12, it moves away from the motor 210 through the screw connection with the upright plate 14, and rotates. The grinding rod 13 is also driven to rotate and move into the hole in the trash can to grind the burrs in the hole. The air pump intakes the jet nozzle 32 to blow away the debris.

[0028] When the grinding rod 13 needs to be replaced, the operator presses the end of the extension rod 29 located outside the grinding rod 13 toward the middle of the grinding rod 13. The end of the extension rod 29 located in the through hole 27 pushes the locking block 25 out of the through hole 27, and the telescopic spring 28 is compressed. At this time, the operator can pull out the grinding rod 13 and replace it with a new grinding rod 13. The groove 26 of the new grinding rod 13 is aligned with the fixing block 23 on the support cylinder 12. When it is first inserted, the locking block 25 will be pressed into the movable groove 24. When the through hole 27 is aligned with the movable groove 24, the telescopic spring 28 begins to extend, inserting one end of the locking block 25 into the through hole 27. The extension rod 29 will be driven, and one end of it will extend out of the through hole 27 by a certain length so that the operator can press it later.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
