Description

Technical Field

[0001] This invention relates to the field of backpack punching equipment technology, specifically to a device for continuous punching of backpacks. Background Technology

[0002] Backpacks come in a variety of materials, including genuine leather, plastic, polyester, canvas, nylon, and cotton linen. In an era that increasingly emphasizes individuality, various styles such as minimalist, retro, and cartoon cater to the needs of fashionistas who want to express their individuality. The manufacturing process of backpacks requires cutting and punching the raw materials.

[0003] In the punching process, existing equipment mostly uses punching drills to punch holes in backpack fabric. The conventional method for removing fabric residue from inside the drill is to install a pushing mechanism inside the drill, relying on the reciprocating motion of the drill to push out the residue. However, under continuous punching conditions on an assembly line, the mechanical joints are prone to metal fatigue damage, requiring frequent shutdowns to replace internal parts, significantly reducing the punching efficiency of the entire production line. To address the aforementioned shortcomings of the existing technology, this invention proposes an improved solution. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a device for continuous punching of backpacks, including a base, an output frame fixedly connected to the top of the base, a push rod fixedly connected to the bottom output end of the output frame, a cutting sleeve fixedly connected to the end of the push rod away from the output frame, a beveled groove formed on the side wall of the cutting sleeve, and a through hole formed on the side wall of the cutting sleeve, and further including:

[0005] The latching mechanism is located on the side wall of the base. The latching mechanism includes an installation groove opened on the side wall of the base, a sliding groove opened on the side wall of the base, and a sliding block slidably connected to the inner wall of the sliding groove.

[0006] The control mechanism is located on the side wall of the base. The control mechanism includes a transfer shell. Two through holes are opened on the side wall of the transfer shell. A flexible hose is fixedly connected to the outer wall of the through hole. A sliding rod is slidably connected to the inner wall of the through hole of the transfer shell.

[0007] An auxiliary mechanism is fixedly installed at the end of the hose away from the transfer shell. The auxiliary mechanism includes a discharge box fixedly connected to the end of the hose away from the transfer shell. A sliding frame is slidably connected to the inner wall of the discharge box. A blocking ball is embedded in the side wall of the sliding frame. An accumulation box is fixedly connected to the top of the discharge box. A piston plate is slidably connected to the inner wall of the accumulation box.

[0008] There is a height difference between the two through holes, and when the air pressure inside the discharge box increases, the piston plate will slide upward under pressure. The sliding frame is a hollow frame, and two protruding blocks are fixed on the side wall of the discharge box, and threaded holes are opened on the protruding blocks.

[0009] Preferably, the latching mechanism further includes:

[0010] A limiting component is fixedly installed on the inner wall of the mounting groove;

[0011] The mounting component is threaded onto the inner wall of the through hole of the sliding block;

[0012] In this process, after the discharge box is inserted into the inner wall of the mounting groove, the two sliding blocks slide relative to each other along the groove. Once in place, the mounting assembly will align with the threaded hole on the side wall of the discharge box.

[0013] Preferably, the control mechanism further includes:

[0014] A shielding component is slidably disposed on the inner wall of the transfer housing;

[0015] The limiting component is fixedly mounted on the top of the transit shell;

[0016] The bottom of the sliding rod is fixedly connected to the top of the shielding component.

[0017] Preferably, the auxiliary mechanism also includes:

[0018] A capping assembly, with threads on the top of the discharge box;

[0019] A reset assembly is fixedly mounted on the top of the piston plate.

[0020] The bottom of the sealing assembly is equipped with a rubber pad, and a circular through hole is opened at the end of the discharge box away from the transfer shell. A rubber ring is fixedly connected to the inner wall of the circular through hole.

[0021] Preferably, the limiting component includes a limiting block fixedly connected to the inner wall of the mounting groove;

[0022] When the discharge box is inserted into the mounting slot, the side wall of the discharge box will fit against the inner wall of the limiting block, thus restricting the position of the discharge box.

[0023] Preferably, the mounting assembly includes a screw threaded into the inner wall of the sliding block through hole;

[0024] When the limiting block is attached to the side wall of the discharge box, when the sliding block slides to its limit along the inner wall of the slide groove, the screw will align with the threaded hole on the side wall of the limiting block, and at the same time the side wall of the sliding block will be attached to the protruding block on the side wall of the discharge box.

[0025] Preferably, the shielding assembly includes a shielding frame that is slidably connected to the inner wall of the transfer housing;

[0026] The top of the shield is fixedly connected to the bottom of the sliding rod.

[0027] Preferably, the limiting component includes a nut fixedly connected to the top of the transfer housing, and a screw is threaded onto the inner wall of the nut;

[0028] The bottom of screw two is rotatably connected to the top of the sliding rod.

[0029] Preferably, the sealing assembly includes a baffle plate bolted to the top of the discharge box;

[0030] When the equipment is in standby mode, the blocking ball protrudes from the arc-shaped outer wall of the discharge box; as the cutting sleeve drives the inclined groove downward, the inclined groove squeezes the blocking ball, pushes the sliding frame to retract, and the high-pressure gas inside the discharge box can be discharged outward through the gap between the blocking ball and the circular through hole.

[0031] Preferably, the reset assembly includes a spring fixedly connected to the top of the piston plate;

[0032] In normal conditions, the spring is in a stretched state. When high pressure occurs inside the discharge box, the piston plate moves upward and compresses the spring, causing it to deform.

[0033] The present invention has the following beneficial effects:

[0034] (1) In view of the problem that conventional discharge structures are prone to wear and tear, which leads to repeated shutdowns for maintenance, the present invention has an auxiliary mechanism and a limiting component inside the equipment. When maintenance is required due to wear of the blocking ball, the operator can first remove two screws, then press the middle finger and thumb of one hand against both sides of the sliding block, hold the discharge box with the other hand, and enter the waiting state. When the equipment is changing the perforated fabric, the operator can quickly separate the two sliding blocks and pull the discharge box outward. Then, the other discharge box is inserted into the installation slot, and the two sliding blocks are pulled to slide back to their original positions to complete the maintenance without stopping the machine. At this time, the sliding block is already stuck on the side wall of the discharge box protrusion block, and the thrust borne by the discharge box will be absorbed by the sliding block. The subsequent installation of screws can be tightened during the operation of the equipment. Through the above design, the maintenance of the perforating equipment without stopping the machine can be realized.

[0035] (2) After the equipment has replaced the discharge box, the operator can rotate the second screw to force the second screw to drive the sliding rod to slide up and down along the inner wall of the through hole of the transfer shell, so that the shielding frame blocks the side wall of the second spare through hole, so that the high pressure gas inside the transfer shell cannot be transmitted to the spare discharge box through the hose. At this time, the operator can directly replace the blocking ball by removing the shielding plate and moving the sliding frame. Through the above design, the normal use of the equipment is not affected when the worker repairs the spare auxiliary mechanism, reducing the difficulty of subsequent maintenance.

[0036] (3) During maintenance, the staff only needs to insert the discharge box into the installation groove, and the limiting block can quickly limit the discharge box. When the side wall of the discharge box is in contact with the limiting block, the sliding block slides along the inner wall of the groove to the limit, and the screw will be aligned with the threaded hole on the side wall of the limiting block, reducing the difficulty of maintenance. In addition, compared with directly replacing the cutting sleeve and its internal structure, this equipment only needs to replace a blocking ball to complete the daily maintenance process immediately, greatly reducing maintenance costs.

[0037] (4) The present invention utilizes the above-mentioned design of high-pressure gas transmission to the inside of the discharge box. A reset component is provided inside the equipment. When high-pressure gas is injected into the discharge box, if the high-pressure gas pressure inside the discharge box is overloaded, the gas pressure will force the piston plate to slide upward along the inner wall of the storage box and compress the spring to generate deformation and accumulate potential energy. When a gap is formed between the subsequent blocking ball and the circular through hole, more high-pressure gas will be discharged outward. Through the above design, when changing the fabric, the piston plate can buffer and accommodate the overloaded gas pressure without the need for system pressure adjustment. The external high-pressure gas pipe can continuously pump stable gas pressure into the discharge box, reducing the failure rate. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1, please refer to Figures 1-8 This invention relates to a device for continuous punching of backpacks, comprising a base 13, an output frame 14 fixedly connected to the top of the base 13, a push rod 15 fixedly connected to the bottom output end of the output frame 14, a cutting sleeve 16 fixedly connected to the end of the push rod 15 away from the output frame 14, a beveled groove 17 formed on the side wall of the cutting sleeve 16, and a through hole 18 formed on the side wall of the cutting sleeve 16, and further comprising:

[0053] The latching mechanism 1 is located on the side wall of the base 13. The latching mechanism 1 includes an installation groove 111 opened on the side wall of the base 13, a sliding groove 112 opened on the side wall of the base 13, and a sliding block 121 slidably connected to the inner wall of the sliding groove 112.

[0054] Control mechanism 2 is located on the side wall of base 13. Control mechanism 2 includes transfer shell 211. Two through holes 212 are opened on the side wall of transfer shell 211. A flexible hose 221 is fixedly connected to the outer wall of the through hole 212. A sliding rod 222 is slidably connected to the inner wall of the through hole of transfer shell 211.

[0055] Auxiliary mechanism 3 is fixedly installed at the end of hose 221 away from transfer shell 211. Auxiliary mechanism 3 includes a discharge box 311 fixedly connected to the end of hose 221 away from transfer shell 211. A sliding frame 312 is slidably connected to the inner wall of discharge box 311. A blocking ball 313 is embedded in the side wall of sliding frame 312. An accumulation box 321 is fixedly connected to the top of discharge box 311. A piston plate 322 is slidably connected to the inner wall of accumulation box 321.

[0056] Two protruding blocks are fixed to the side wall of the discharge box 311, and threaded holes are provided on the protruding blocks, presenting a shape as follows. Figure 9 The position of K is shown in the middle.

[0057] Before use, install the equipment in the required position, then connect the various pipes to ensure that the canvas can pass through the side through-hole slot of the base 13. During this process, the output frame 14 with the cutting sleeve 16 moves downward and punches the canvas inside the through-hole slot of the base 13.

[0058] The locking mechanism 1 also includes:

[0059] Limiting component 11 is fixedly disposed on the inner wall of mounting groove 111;

[0060] Mounting component 12 is threadedly fitted onto the inner wall of the through hole of sliding block 121;

[0061] The auxiliary mechanism 3 has two sets, and is supplied with air by the control mechanism 2. When the shield 213 is between the two through holes 212, the high air pressure inside the transfer shell 211 can be transmitted to the discharge box 311 through the hose 221. The discharge box 311 forms a high air pressure. When the cutting sleeve 16 moves downward, the inclined groove 17 contacts the outer wall of the blocking ball 313, forcing the blocking ball 313 and the sliding frame 312 to move a short distance along the inner wall of the discharge box 311 towards the hose 221. At this time, there is a small gap between the blocking ball 313 and the circular through hole. The high pressure gas inside the discharge box 311 will be discharged outward through the small gap and finally enter the interior of the cutting sleeve 16 through the through hole 18. The airflow generated will push the cloth punching residue remaining inside the cutting sleeve 16 downward to be discharged.

[0062] Control mechanism 2 also includes:

[0063] The shielding component 21 is slidably disposed on the inner wall of the transfer shell 211;

[0064] Restriction component 22 is fixedly disposed on the top of the transfer shell 211;

[0065] The bottom of the sliding rod 222 is fixedly connected to the top of the shielding assembly 21.

[0066] Auxiliary mechanism 3 also includes:

[0067] A capping assembly 31 is threaded onto the top of the discharge box 311;

[0068] Reset assembly 32 is fixedly mounted on the top of piston plate 322;

[0069] The bottom of the cover assembly 31 is provided with a rubber pad, and the end of the discharge box 311 away from the transfer shell 211 is provided with a circular through hole, and a rubber ring is fixedly connected to the inner wall of the circular through hole.

[0070] Example 2, please refer to Figures 4-10 The present invention is a device for continuous punching of backpacks. Based on the first embodiment, the limiting component 11 includes a limiting block 113 fixedly connected to the inner wall of the mounting groove 111.

[0071] To address the issue of frequent downtime for maintenance caused by wear on conventional discharge structures, an auxiliary mechanism 3 and a limiting component 11 are installed inside the equipment. When maintenance is required due to wear of the blocking ball 313, the operator can first remove two screws 122, then press the middle finger and thumb of one hand against both sides of the sliding block 121, hold the discharge box 311 with the other hand, and enter a waiting state. When changing the perforated fabric, the operator can quickly separate the two sliding blocks 121, pull out the internal discharge box 311, and then insert the other discharge box 311 into the mounting slot 111. At the same time, the two sliding blocks 121 are pulled to slide back to their original position, completing the maintenance without stopping the machine. At this time, the sliding block 121 is locked in the side wall of the protruding block of the discharge box 311, and the thrust on the discharge box 311 will be absorbed by the sliding block 121. The screws 122 can be tightened during the operation of the equipment. Through the above design, the perforation equipment can be maintained without stopping the machine.

[0072] Mounting component 12 includes a screw 122 that is threaded onto the inner wall of the through hole of sliding block 121;

[0073] When the side wall of the discharge box 311 is in contact with the limiting block 113, the sliding block 121 slides relative to the inner wall of the slide groove 112 to the limit, and the screw 122 will align with the threaded hole on the side wall of the limiting block 113. At the same time, the side wall of the sliding block 121 will be in contact with the protruding block on the side wall of the discharge box 311.

[0074] The shielding assembly 21 includes a shielding frame 213 that is slidably connected to the inner wall of the transfer housing 211;

[0075] During maintenance, the staff only needs to insert the discharge box 311 into the mounting groove 111, and the limiting block 113 can quickly limit the discharge box 311. When the side wall of the discharge box 311 is in contact with the limiting block 113, the sliding block 121 slides relative to the inner wall of the sliding groove 112 to the limit, and the screw 122 will align with the threaded hole on the side wall of the limiting block 113, reducing the difficulty of maintenance. In addition, compared with directly replacing the cutting sleeve 16 and its internal structure, this equipment only needs to replace a blocking ball 313 to complete the daily maintenance procedure immediately, greatly reducing maintenance costs.

[0076] The limiting component 22 includes a nut 224 fixedly connected to the top of the transfer housing 211, and a screw 223 is threadedly connected to the inner wall of the nut 224;

[0077] The bottom of screw 223 is rotatably connected to the top of sliding rod 222.

[0078] The cover assembly 31 includes a baffle 314 bolted to the top of the discharge box 311;

[0079] After the equipment has replaced the discharge box 311, the operator can rotate screw 223 to force the sliding rod 222 to slide up and down along the inner wall of the through hole of the transfer shell 211. This causes the baffle 213 to block the side wall of the spare through hole 212, preventing the high-pressure gas inside the transfer shell 211 from being transmitted to the spare discharge box 311 through the hose 221. At this time, the operator can remove the baffle 314 and move the sliding rod 312 to present the following... Figure 10 As shown, the blocking ball 313 can be directly replaced. Through the above design, the normal use of the equipment is not affected when the worker repairs the backup auxiliary mechanism 3, thus reducing the difficulty of subsequent maintenance.

[0080] The reset assembly 32 includes a spring 323 fixedly connected to the top of the piston plate 322;

[0081] Utilizing the aforementioned design of transmitting high-pressure gas to the discharge box 311, a reset component 32 is installed inside the equipment. When high-pressure gas is injected into the discharge box 311, if the high-pressure gas pressure inside the discharge box 311 becomes overloaded, the gas pressure will force the piston plate 322 to slide upward along the inner wall of the storage box 321, and compress the spring 323 to generate deformation and accumulate potential energy. When a gap is subsequently formed between the blocking ball 313 and the circular through hole, more high-pressure gas will be discharged outward. Through the above design, when changing the fabric, the piston plate 322 can buffer and accommodate the overloaded gas pressure without the need for system pressure adjustment. The external high-pressure gas pipe can continuously pump stable gas pressure into the discharge box 311, reducing the failure rate.

[0082] A specific application of this embodiment is as follows: Before use, the equipment is installed in the required position, and then the various pipes are connected to ensure that the canvas can pass through the side through-hole groove of the base 13. During this process, the output frame 14 moves downward with the cutting sleeve 16 through the through-hole groove of the base 13 and performs a punching process on the canvas inside the through-hole groove of the base 13.

[0083] The auxiliary mechanism 3 has two sets, and is supplied with air by the control mechanism 2. When the shield 213 is between the two through holes 212, the high air pressure inside the transfer shell 211 can be transmitted to the discharge box 311 through the hose 221. The discharge box 311 forms a high air pressure. When the cutting sleeve 16 moves downward, the inclined groove 17 contacts the outer wall of the blocking ball 313, forcing the blocking ball 313 and the sliding frame 312 to move a short distance along the inner wall of the discharge box 311 towards the hose 221. At this time, there is a small gap between the blocking ball 313 and the circular through hole. The high pressure gas inside the discharge box 311 will be discharged outward through the small gap and finally enter the interior of the cutting sleeve 16 through the through hole 18. The airflow generated will push the cloth punching residue remaining inside the cutting sleeve 16 downward to be discharged.

[0084] To address the issue of frequent downtime for maintenance caused by wear on conventional discharge structures, an auxiliary mechanism 3 and a limiting component 11 are installed inside the equipment. When maintenance is required due to wear of the blocking ball 313, the operator can first remove two screws 122, then press the middle finger and thumb of one hand against both sides of the sliding block 121, hold the discharge box 311 with the other hand, and enter a waiting state. When changing the perforated fabric, the operator can quickly separate the two sliding blocks 121, pull out the internal discharge box 311, and then insert the other discharge box 311 into the mounting slot 111. At the same time, the two sliding blocks 121 are pulled to slide back to their original position, completing the maintenance without stopping the machine. At this time, the sliding block 121 is locked in the side wall of the protruding block of the discharge box 311, and the thrust on the discharge box 311 will be absorbed by the sliding block 121. The screws 122 can be tightened during the operation of the equipment. Through the above design, the perforation equipment can be maintained without stopping the machine.

[0085] After the equipment has replaced the discharge box 311, the operator can rotate screw 223 to force the sliding rod 222 to slide up and down along the inner wall of the through hole of the transfer shell 211. This causes the baffle 213 to block the side wall of the spare through hole 212, preventing the high-pressure gas inside the transfer shell 211 from being transmitted to the spare discharge box 311 through the hose 221. At this time, the operator can remove the baffle 314 and move the sliding rod 312 to present the following... Figure 10 As shown, the blocking ball 313 can be directly replaced. Through the above design, the normal use of the equipment is not affected when the worker repairs the backup auxiliary mechanism 3, thus reducing the difficulty of subsequent maintenance.

[0086] During maintenance, the staff only needs to insert the discharge box 311 into the mounting groove 111, and the limiting block 113 can quickly limit the discharge box 311. When the side wall of the discharge box 311 is in contact with the limiting block 113, the sliding block 121 slides relative to the inner wall of the sliding groove 112 to the limit, and the screw 122 will align with the threaded hole on the side wall of the limiting block 113, reducing the difficulty of maintenance. In addition, compared with directly replacing the cutting sleeve 16 and its internal structure, this equipment only needs to replace a blocking ball 313 to complete the daily maintenance procedure immediately, greatly reducing maintenance costs.

[0087] Utilizing the aforementioned design of transmitting high-pressure gas to the discharge box 311, a reset component 32 is installed inside the equipment. When high-pressure gas is injected into the discharge box 311, if the high-pressure gas pressure inside the discharge box 311 becomes overloaded, the gas pressure will force the piston plate 322 to slide upward along the inner wall of the storage box 321, and compress the spring 323 to generate deformation and accumulate potential energy. When a gap is subsequently formed between the blocking ball 313 and the circular through hole, more high-pressure gas will be discharged outward. Through the above design, when changing the fabric, the piston plate 322 can buffer and accommodate the overloaded gas pressure without the need for system pressure adjustment. The external high-pressure gas pipe can continuously pump stable gas pressure into the discharge box 311, reducing the failure rate.
