Description

Technical Field

[0001] This utility model relates to the field of packaging punching, and in particular to the punching mechanism of a vertical packaging machine. Background Technology

[0002] Currently, Chinese utility model patent CN201816087U discloses an automatic punching device for a fully automatic vertical filling and packaging machine. Although this punching device can push the punch forward using a cylinder, it still has other problems during use. For example, it does not have an automatic material pushing function. Before punching, the material inside the packaging bag is already heat-sealed, which expands it. At this time, when the packaging bag falls down, it is easy to sit on the pad, requiring personnel to assist in pushing it down, which increases the workload of personnel. Moreover, it is not convenient to replace the punch. After long-term use, the end of the punch will become dull, requiring personnel to put the new one in and remove the old one. Disassembling and assembling the punch requires the use of tools to remove the screws, reducing the work efficiency of personnel. In order to solve the above problems, we propose a punching mechanism for a vertical packaging machine. Utility Model Content

[0003] The purpose of this invention is to provide a punching mechanism for a vertical packaging machine, which solves the problems of existing punching devices lacking auxiliary pushing-down function and being inconvenient to replace the punch.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punching mechanism for a vertical packaging machine, including a fixed frame, a cylinder is bolted through the front of the fixed frame, an mounting bracket is installed on the piston end of the cylinder, a pad and a fixing plate are bolted to the inside of the fixed frame and the inside of the mounting bracket respectively, a pusher frame is slidably sleeved on the surface of the pad, a fixing spring is bolted between the back of the pusher frame and the fixed frame through a spring fixing piece, a punch is inserted through the back of the fixing plate, two mounting slots are opened inside the fixing plate, a clamping plate is clamped on both sides of the punch, a limit spring is bolted between the other side of the clamping plate and the mounting slot through a spring fixing piece, and a groove is opened on the front of the pad.

[0005] The above technical solution can provide an auxiliary pushing function, reduce the burden of personnel assisting, improve the processing efficiency of the equipment, facilitate the replacement of the punch, simplify operation and save labor, improve the work efficiency of personnel, and has high practicality.

[0006] The present invention is further configured such that a damper is installed between the back of the pusher frame and the fixing frame.

[0007] By adopting the above technical solution, the damper can be used to suppress the jumping of the fixed spring and consume the kinetic energy stored in the fixed spring, thereby reducing the resonance amplitude and improving stability.

[0008] The present invention is further configured such that: two limiting rods are provided through the front of the mounting bracket, and both ends of the limiting rods are welded to the interior of the fixing bracket.

[0009] By adopting the above technical solution, the installation frame can be limited by the setting of the limiting rod, thereby improving the stability of the installation frame during the forward and backward movement.

[0010] The present invention is further configured such that: mounting plates are welded to both sides of the fixing frame, and mounting holes are provided inside the mounting plates.

[0011] By adopting the above technical solution, the mounting plate and mounting holes make it easy for personnel to fix the bracket with screws, reducing the trouble of temporary drilling.

[0012] The present invention is further configured such that: a guide rod is installed inside the mounting groove, a guide groove is provided on the other side of the card plate, and the other end of the guide rod extends into the interior of the guide groove.

[0013] By adopting the above technical solution, the guide rod and guide groove can limit the position of the card plate and prevent the card plate from tilting or moving inward during the process.

[0014] The present invention is further configured such that: a pull rod is installed on the top of the card plate, a sliding groove communicating with the mounting groove is opened on the top of the fixing plate, and the other end of the pull rod extends to the outside of the sliding groove.

[0015] By adopting the above technical solution, the design of the pull rod and sliding groove makes it easy for personnel to pull the pallet outward.

[0016] The present invention is further configured such that the surfaces of the fixing frame, mounting frame, pad, and fixing plate are all coated with anti-corrosion coating.

[0017] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the surfaces of the fixing frame, mounting frame, pad, and fixing plate can be improved.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model first fixes the fixing frame to the outer shell of the packaging machine with screws. After the fixing frame is fixed, the cylinder is activated to push the mounting frame and the pad plate forward. When the mounting frame moves forward, it will contact the pusher frame and push the pusher frame backward. When the pusher frame moves backward, it will press the fixing spring and the damper. When the fixing plate moves forward to the end, the punch will penetrate the packaging and extend into the groove. After the punching is completed, as the mounting frame moves forward, the pusher frame will reset and push the packaging bag placed on the pad plate down. It can have an auxiliary pushing function, reduce the burden of personnel to assist, and improve the processing efficiency of the equipment.

[0020] 2. This utility model allows for easy punch replacement by using one hand to push two levers outward when the punch needs to be replaced. As the levers move outward, they also move the retaining plate. When the retaining plate moves outward, it not only compresses the limiting spring, causing it to contract and deform, but also separates from the retaining groove inside the punch. After the levers are pushed all the way out, the punch can be pulled out with the other hand. This makes it easy to replace the punch, is simple and labor-saving, improves the work efficiency of personnel, and is highly practical. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 and Figure 2 The punching mechanism of the vertical packaging machine includes a fixed frame 1. A cylinder 2 is bolted through the front of the fixed frame 1. A mounting frame 3 is installed on the piston end of the cylinder 2. A pad 4 and a fixing plate 5 are bolted to the inside of the fixed frame 1 and the mounting frame 3, respectively. A pusher frame 6 is slidably sleeved on the surface of the pad 4. A fixing spring 7 is bolted between the back of the pusher frame 6 and the fixed frame 1 through a spring fixing plate. The fixed frame 1 is first fixed to the outer shell of the packaging machine by screws. After the fixed frame 1 is fixed, the cylinder 2 is activated to push the mounting frame 3 and the pad 4 forward. When the mounting frame 3 moves forward, it will contact the pusher frame 6 and push the pusher frame 6 backward. When the pusher frame 6 moves backward, it will press the fixing spring 7 and the damper 11. When the fixing plate 5 moves forward to the end, the punch 18 will penetrate the packaging and extend into the groove 10. After punching is completed, as the mounting frame 3 moves forward, the pusher frame 6 will reset and push the packaging bag placed on the pad 4 off. It can have an auxiliary pushing function, reduce the burden of personnel to assist, and improve the processing efficiency of the equipment.

[0028] refer to Figure 2 A damper 11 is installed between the back of the pusher frame 6 and the fixed frame 1. The damper 11 can suppress the jumping of the fixed spring 7 and consume the kinetic energy stored in the fixed spring 7, thereby reducing the resonance amplitude and improving stability.

[0029] refer to Figure 1 and Figure 2 Two limiting rods 12 are provided through the front of the mounting frame 3. Both ends of the limiting rods 12 are welded to the inside of the fixed frame 1. By setting the limiting rods 12, the mounting frame 3 can be limited, which improves the stability of the mounting frame 3 during the back and forth movement.

[0030] refer to Figure 1 and Figure 2 Mounting plates 13 are welded to both sides of the fixing frame 1. Mounting plates 13 have mounting holes inside. The mounting plates 13 and mounting holes make it easy for personnel to fix the fixing frame 1 with screws, reducing the trouble of temporary drilling.

[0031] refer to Figure 1 and Figure 2 The surfaces of the fixing frame 1, mounting frame 3, pad 4 and fixing plate 5 are all coated with anti-corrosion paint. The anti-corrosion paint can improve the anti-corrosion and moisture-proof effect of the surfaces of the fixing frame 1, mounting frame 3, pad 4 and fixing plate 5.

[0032] Brief description of the usage process: First, fix the fixing frame 1 to the outer shell of the packaging machine with screws. After the fixing frame 1 is fixed, start the cylinder 2 to push the mounting frame 3 and the pad 4 forward. When the mounting frame 3 moves forward, it will contact the pusher frame 6 and push the pusher frame 6 backward. When the pusher frame 6 moves backward, it will press the fixing spring 7 and the damper 11. When the fixing plate 5 moves forward to the end, the punch 18 will penetrate the packaging and extend into the groove 10. After the punching is completed, as the mounting frame 3 moves forward, the pusher frame 6 will reset and push the packaging bag placed on the pad 4 off.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 and Figure 3The punching mechanism of the vertical packaging machine has a punch 18 inserted through the back of the fixed plate 5. The fixed plate 5 has two mounting slots 19. Both sides of the punch 18 are clamped with clamping plates 8. The other side of the clamping plate 8 and the mounting slot 19 are connected to a limit spring 9 by a spring fixing plate. The front of the pad plate 4 has a groove 10. When the punch 18 needs to be replaced, the two pull rods 16 are pushed outward with one hand. When the pull rods 16 move outward, they will drive the clamping plates 8 to move together. When the clamping plates 8 move outward, they will not only compress the limit spring 9 to shrink and deform, but also separate from the clamping slot inside the punch 18. When the pull rods 16 are pushed outward to the end, the punch 18 can be pulled out with the other hand. This makes it easy to replace the punch 18, and the operation is simple and labor-saving, improving the work efficiency of the personnel and making it highly practical.

[0035] refer to Figure 3 The mounting groove 19 is equipped with a guide rod 14, and the other side of the clamping plate 8 is provided with a guide groove 15. The other end of the guide rod 14 extends into the interior of the guide groove 15. Through the setting of the guide rod 14 and the guide groove 15, the clamping plate 8 can be limited to prevent it from tilting or moving inward.

[0036] refer to Figure 1 A pull rod 16 is installed on the top of the card plate 8, and a sliding groove 17 communicating with the mounting groove 19 is opened on the top of the fixing plate 5. The other end of the pull rod 16 extends to the outside of the sliding groove 17. With the setting of the pull rod 16 and the sliding groove 17, it is easy for personnel to pull the card plate 8 outward.

[0037] Brief description of the usage process: When it is necessary to replace the punch 18, use one hand to push the two levers 16 outward. When the levers 16 move outward, they will drive the clamping plate 8 to move together. When the clamping plate 8 moves outward, it will not only compress the limit spring 9 to cause it to contract and deform, but also separate from the groove inside the punch 18. After the levers 16 are pushed outward to the end, the punch 18 can be pulled out with the other hand.

[0038] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
