Abstract
Description
Technical Field
[0001] This utility model relates to the field of perforation processing technology, and in particular to a perforation device for plastic products. Background Technology
[0002] For practical and functional reasons, plastic products often require perforation during manufacturing. When transporting and storing plastic products, many items need to be stacked. The perforations disrupt the airtightness between stacked items, preventing them from sticking together due to vacuum adhesion and facilitating quick separation.
[0003] Existing plastic perforation devices typically use a base, a lifting seat, a lifting block, and a punch. The lifting seat is vertically fixed to the base, the punch is fixed to the lifting block, and the lifting block is slidably moved up and down on the lifting seat. During perforation, the plastic product is placed under the punch, and the lifting block is pressed down to force the punch to punch a through-hole in the surface of the plastic product. However, existing plastic perforation devices can only punch through-holes of a single size. When other sizes of through-holes are needed, a different plastic perforation device is required; this lack of versatility necessitates improvement. Utility Model Content
[0004] The purpose of this invention is to provide a perforation device with good versatility that can create through holes of different sizes on the surface of plastic products.
[0005] This utility model discloses a perforation device for plastic products, including a base, a lifting seat, a support column, a lever, and a perforation assembly. The lifting seat is disposed on the base, and the support column is vertically fixedly disposed on the lifting seat. One end of the lever is hinged to the support column. The perforation assembly includes a lifting rod, a punch, a spring, and a locking limiter. A lifting hole is vertically formed in the lifting seat, and the lifting rod passes through the lifting hole. The locking limiter is detachably fixedly disposed at the top end of the lifting rod. The spring is sleeved around the lifting rod, and its two ends abut against the lifting seat and the locking limiter, respectively. A mounting hole is vertically formed in the lifting rod, and the top end of the punch passes through the mounting hole. A fixing bolt is threaded to the bottom end of the outer surface of the lifting rod, and the fixing bolt abuts against the punch. The lever presses down on the lifting rod, causing the punch to perforate the surface of the plastic product.
[0006] Preferably, a limit post is vertically fixed on the lifting seat, so that the lifting rod is located between the support column and the limit post, and the limit post limits the descent of the locking limit member.
[0007] Preferably, the limiting post and the support post are both threadedly connected to the lifting seat.
[0008] Preferably, the locking and limiting component includes a limiting screw and a clamp. The limiting screw is threaded into the mounting hole, the clamp is tightened with the limiting screw, one end of the spring abuts against the clamp, and the limiting post limits the descent of the clamp.
[0009] Preferably, the top end of the limiting screw is rounded.
[0010] Preferably, a slider is vertically fixed to the inner wall of the lifting hole, and a groove is vertically formed on the outer surface of the lifting rod, with the slider being engaged in the groove.
[0011] Preferably, a positioning plate is fixedly provided on the base, and a positioning hole is provided on the surface of the positioning plate. A perforating platform is embedded in the positioning hole, and a clearance hole is formed through the perforating platform. The clearance hole is located directly below the punch.
[0012] As can be seen from the above description of this utility model, this utility model has the following beneficial effects:
[0013] 1. In this perforation device, the punch is inserted into the mounting hole at the bottom of the lifting rod and is fixed by a fixing bolt, thereby making the punch and the lifting rod detachable and easy to install and remove; thus, the perforation device has good versatility and can perforate different types of through holes on the surface of plastic products.
[0014] 2. A limit post is vertically fixed on the lifting base. The locking and limiting component is configured to include a limit screw and a clamp. The limit screw is threaded into the mounting hole to be fixed to the top of the lifting rod. The clamp is tightened with the limit screw. This makes the limit post located below one end of the clamp. Thus, the limit post limits the descent of the clamp to prevent the punch from excessively pressing the surface of the plastic product.

[0023] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-7 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
[0024] Reference Figure 1 , Figure 2 and Figure 3 A perforation device for plastic products includes a base 1, a lifting seat 2, a support column 3, a lever 4, and a perforation assembly 5. The lifting seat 2 is fixedly mounted on the base 1. The perforation assembly 5 includes a lifting rod 51, a punch 52, a spring 53, and a locking limit member 54. A lifting hole 21 is vertically formed in the lifting seat 2. The lifting rod 51 is slidably moved up and down within the lifting hole 21 of the lifting seat 2. The spring 53 is sleeved around the lifting rod 51, with one end of the spring 53 abutting against the lifting seat 2. The locking limit member 54 is fixed to the top of the lifting rod 51, with the other end of the spring 53 abutting against the locking limit member 54, thereby keeping the lifting rod 51 inserted within the lifting hole 21 of the lifting seat 2.
[0025] Reference Figure 2 , Figure 4 and Figure 5The punch 52 is detachably mounted on the bottom end of the lifting rod 51. A mounting hole 511 is vertically formed in the lifting rod 51. The top end of the punch 52 is inserted into the mounting hole 511, and a fixing bolt 55 is threaded onto the bottom end of the outer surface of the lifting rod 51, so that the fixing bolt 55 abuts against the punch 52 inserted into the mounting hole 511. This allows for detachable mounting of the punch 52 and the lifting rod 51, enabling the punch 52 mounted on the bottom end of the lifting rod 51 to be disassembled and replaced. This allows the perforating device to perforate through holes of different sizes on the surface of plastic products. The support column 3 is vertically fixed on one side of the lifting seat 2, and one end of the lever 4 is hinged to the support column 3, so that the lever 4 abuts against the locking limit member 54. The lever 4 is pressed down to compress the spring 53, causing the lifting rod 51 to descend, thereby causing the punch 52 located at the bottom of the lifting rod 51 to punch a through hole in the surface of the plastic product; after the punching is completed on the surface of the plastic product, the lifting rod 51 will drive the punch 52 to rise and reset under the action of the spring 53.
[0026] To ensure the lifting rod 51 remains stable during lifting, a slider 22 is vertically fixed to the inner wall of the lifting hole 21, and a corresponding groove 512 is vertically formed on the outer surface of the lifting rod 51. When the lifting rod 51 passes through the lifting hole 21, the slider 22 is engaged in the groove 512. During the lifting process within the lifting hole 21, the lifting rod 51 slides vertically along the slider 22, thus ensuring the stability of the lifting rod 51 during lifting.
[0027] Reference Figure 2 and Figure 5 To prevent excessive downward pressure on the lifting rod 51 by the lever 4, a limit post 23 is vertically fixed on the lifting seat 2. The limit post 23 is located on the side of the lifting rod 51 away from the support column 3, so that the lifting rod 51 is located between the support column 3 and the limit post 23. The locking limit member 54 is configured to include a limit screw 541 and a clamp 542. The limit screw 541 is threadedly fixed to the top of the lifting rod 51, and the clamp 542 is clamped and fixed to the limit screw 541. The two ends of the spring 53 abut against the lifting seat 2 and the clamp 542 respectively, so that one end of the clamp 542 is directly above the limit post 23. The lever 4 is pressed down to drive the lifting rod 51 down until the clamp 542 abuts against the top of the limit post 23, so that the punch 52 punches a through hole on the surface of the plastic product. The setting of the limiting post 23 plays a limiting role in the descent of the lever 4 driving the lifting rod 51, so as to prevent the punch 52 from excessively pressing the surface of the plastic product.
[0028] The limiting post 23 and the upright post are both fixed to the lifting base 2 by threaded connection. This allows adjustment of the depth of the threaded connection of the limiting post 23 within the lifting base 2, thereby adjusting the height of the top of the limiting post 23. Alternatively, the installation height of the upright post 3 can be adjusted by adjusting the depth of the threaded connection of the upright post 3 within the lifting base 2. After adjusting the installation height of the limiting post 23, the maximum downward pressure of the lever 4 on the lifting rod 51 is adjusted to meet the perforation requirements of the plastic product. After the downward pressure of the lever 4 causes the punch 52 to complete the perforation of the plastic product surface, the lifting rod 51 will drive the punch 52 to rise under the elastic force of the spring 53, so that the punch 52 is pulled out from the through hole punched in the plastic product, thus completing the punching of the through hole on the surface of the plastic product. Furthermore, the top end of the limiting screw 541 is set as a round head 5411, so that when the lever 4 is pressed down, there is a larger contact area with the top end of the limiting screw 541, thereby enhancing the stability of the limiting screw 541 during the pressing process; and the limiting screw 541 with a round head 5411 is less prone to wear or direct slippage during the contact with the lever 4.
[0029] Reference Figure 6 and Figure 7 A positioning plate 6 is horizontally mounted on the base 1 and secured to the base 1 with bolts. A positioning hole 61 is formed in the center of the positioning plate 6, positioned directly below the punch 52. A perforating platform 7 is fitted into the positioning hole 61, with a clearance hole 71 at the center of its surface. The clearance holes 71 of different perforating platforms 7 are of different sizes and are matched to the sizes of different models of punches 52. After the perforating platform 7 is fitted into the positioning hole 61 of the positioning plate 6, the perforating platform 7 protrudes from the surface of the positioning plate 6, with the clearance hole 71 positioned directly below the punch 52. When perforating the surface of a plastic product, the plastic product is placed on the perforating platform 7; after the punch 52 descends to complete the perforation of the plastic product surface, the punch 52 passes into the clearance hole 71 of the perforating platform 7. The perforation platform 7 provides support for the perforation process of plastic products; and the perforation platform 7 is installed in the positioning hole 61 of the positioning plate 6 by snap-fit, so that the perforation platform 7 can be replaced and the clearance hole 71 of the perforation platform 7 after replacement can match the punch 52 model.
[0030] The specific implementation principle of this application embodiment is as follows: Before using the piercing device to pierce the surface of a plastic product, a punch 52 corresponding to the required piercing size is selected and installed at the bottom end of the lifting rod 51, so that the fixing bolt 55 threaded to the outer surface of the lifting rod 51 is tightly abutted and fixed to the punch 52 inserted in the mounting hole 511. A piercing platform 7 corresponding to the punch 52 model is then selected and fitted into the positioning hole 61 of the positioning plate 6.
[0031] When perforating the surface of a plastic product, the plastic product is placed on the perforation table 7. Then, lever 4, which abuts against the limiting screw 541, is pressed down, causing clamp 542, which is fastened to the limiting screw 541, to compress the spring 53. Simultaneously, lever 4 is pressed down to drive the lifting rod 51 downwards until lever 4 abuts against the top of the limiting post 23. The limiting post 23 prevents excessive pressing of lever 4. The lifting rod 51 descends, causing the punch 52 to punch a through hole in the surface of the plastic product. After punching the through hole, the punch 52 passes through the clearance hole 71 of the perforation table 7. After punching the through hole, the pressure on lever 4 is stopped, causing the lifting rod 51 to rise under the elastic force of the spring 53, thereby pulling the punch 52 out of the through hole in the surface of the plastic product, thus completing the perforation process on the surface of the plastic product. The punch 52 can be replaced with a corresponding punch according to the size of the through hole required for the plastic product, making the punch 52 more versatile in processing; and the punch 52 is very easy to disassemble and replace.
[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
