Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a wire feeding mechanism for a glue-pin packaging equipment. Background Technology

[0002] Existing adhesive-stapling packaging equipment includes an adhesive-applying module and a stapling module. The adhesive-applying module uses adhesive tape to bond the outer periphery of the paper tray, making the connection between the top and bottom surfaces more secure. The stapling module uses wire bent into a stapling shape and inserted into the center of the paper tray to make the connection more secure.

[0003] Currently used staple packaging equipment consists of a wire feeding mechanism and a stamping mechanism that bends wires of a specific length into N-shaped staples and inserts them into the center of the paper tray. Both mechanisms are stationary, and the end of the wire feeding mechanism is connected to the wire inlet hole of the stamping mechanism via a guide seat. The wire fed by the wire feeding mechanism is precisely fed into the wire inlet hole of the stamping mechanism through the guide hole on the guide seat. When the wire is in place, a cutting component cuts the wire. However, the portion of the wire remaining within the guide seat is wasted material, resulting in high material consumption and costs during batch processing. Therefore, it is necessary to improve the wire feeding mechanism of existing staple packaging equipment to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a wire feeding mechanism for a glue-pin packaging equipment. The wire feeding length of this utility model can be adjusted according to actual needs, which has the advantages of saving consumables and reducing costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding mechanism for a glue-pin packaging device, which is installed in front of the stamping mechanism to feed iron wire into the stamping mechanism, including a mounting frame, a material tray for winding iron wire on the mounting frame, a conveying component for transmitting the iron wire pulled out from the material tray, and a cutting component for cutting the iron wire fed into the stamping mechanism; the cutting component includes a wire guide seat and a cutter, the wire guide seat is movably installed on the mounting frame in the direction close to or away from the stamping mechanism, the wire guide seat has a wire guide hole for the iron wire to pass through, the wire guide seat also has a knife groove communicating with the wire guide hole, the cutter is movably installed in the knife groove, and the cutter has a first position misaligned with the iron wire and a second position cutting the iron wire when it moves in the knife groove.

[0006] By adopting the above technical solution, the wire guide seat of the cutting component is designed as a movable structure. During operation, the wire guide seat is first moved to abut against the corresponding wire inlet hole of the stamping mechanism, and the conveying component is activated to transport the wire. A certain length of wire is then introduced according to design requirements. The wire is then cut by the wire assembly and withdrawn from the wire guide seat. This process is repeated multiple times to process multiple nails. Since the wire feeding length can be adjusted according to actual needs, there is no waste of materials, thus it has the advantages of saving consumables and reducing costs.

[0007] The present invention is further configured such that the mounting bracket is provided with a guide rail extending toward the stamping mechanism, and the wire guide seat is provided with a guide groove that cooperates with the guide rail.

[0008] By adopting the above technical solution, the guide wire seat can be guided, so that it can be oriented and move stably toward or away from the stamping mechanism.

[0009] The present invention is further configured such that the cutting assembly includes a first motor, a gear, and a rack. The first motor is mounted on a mounting bracket, the gear is linked to the motor shaft of the first motor, the rack is connected to the side of the wire guide seat, and the extending direction of the rack is parallel to the extending direction of the guide rail. The gear meshes with the rack.

[0010] By adopting the above technical solution, the first motor drives the guide wire seat to move through a gear and rack mechanism, which not only provides precise and stable distance control, but also ensures good reliability and durability of the transmission structure.

[0011] The present invention is further configured such that the cutting assembly includes a blade holder, a pressing force component, and a return spring. The blade holder is disposed above the wire guide seat, and the upper end of the cutter is connected to the blade holder. The pressing force component cooperates with the blade holder to apply a downward force to the blade holder, so that the blade holder drives the cutter downward and cuts the wire. The return spring is disposed between the wire guide seat and the blade holder, and is used for the blade holder and the cutter to return from the second position to the first position.

[0012] By adopting the above technical solution, the pressing power component provides downward pressing power to the cutter, and the return spring provides upward returning power to the cutter, thereby realizing the cutting action of the cutter on the wire. The structure is simple and reliable, and is conducive to assembly and production.

[0013] The present invention is further provided that the cutter has a hole in the middle for the wire to pass through.

[0014] By adopting the above technical solution, the wire is cut by misaligning the blade hole and the guide wire hole, which allows for a longer cutting blade, thus making its operation more stable and reliable.

[0015] The present invention is further configured such that the guide wire seat includes an upper seat and a lower seat connected together by fasteners, the cutter groove includes an upper groove on the upper seat and a lower groove on the lower seat, the cross-sectional shape of the upper groove is similar to that of the cutter, the cross-sectional area of ​​the lower groove is larger than that of the upper groove, and a limiting protrusion is provided at the part of the cutter located in the lower groove, the limiting protrusion forming a limit when it moves upward and abuts against the lower end of the upper seat.

[0016] By adopting the above technical solution, the upward return stroke of the cutter can be limited to prevent it from being pushed out by the return spring. At the same time, when it reaches the upper limit position, the spring force provided by the return spring to the cutter can ensure that it is stably located in the first position.

[0017] The present invention is further configured such that the pressing power component includes a first cylinder, a rocker arm, and a hinge seat. The hinge seat is mounted on the wire guide seat, and the middle part of the rocker arm is rotatably connected to the hinge seat. A drive shaft is provided on the extended end of the first cylinder.

A roller is rotatably provided on the tool holder, and the lower side of the end of the rocker arm away from the first cylinder rolls with the outer circumference of the roller.

[0018] By adopting the above technical solution, when the first cylinder extends, the rocker arm swings in the first direction and applies downward pressure to the tool holder. When the first cylinder retracts, the rocker arm swings in the second direction, and the tool holder moves upward under the action of the return spring. The rocker arm and the roller on the tool holder roll together, which greatly reduces the friction between the two. This not only reduces friction noise but also improves the service life of the mating parts.

[0019] The present invention is further configured such that the conveying assembly includes a conveying frame mounted on a mounting frame, a first guide wheel and a second guide wheel rotatably mounted on the conveying frame, and a motor drive unit mounted on the side of the conveying frame and connected to the first guide wheel.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: As attached Figures 1-6 The wire feeding mechanism of the glue-pin packaging equipment shown is located before the stamping mechanism 2 and is used to feed the wire into the stamping mechanism 2 (in the attached...). Figure 1 In this design, the wire feeding mechanism 1 is located next to the stamping mechanism 2. The stamping mechanism 2 is existing technology, so its specific structure will not be described in detail here. It includes a mounting frame 3, a material tray 4 for winding iron wire mounted on the mounting frame 3, a conveying assembly 5 for conveying the iron wire pulled out from the material tray 4, and a cutting assembly 6 for cutting the iron wire fed into the stamping mechanism 2. The cutting assembly 6 includes a wire guide seat 7 and a cutter 8. The wire guide seat 7 is movably mounted on the mounting frame 3 in the direction close to or away from the stamping mechanism 2. The wire guide seat 7 has a wire guide hole 9 for the iron wire to pass through. The wire guide seat 7 also has a cutter groove 10 that communicates with the wire guide hole 9. The cutter 8 is movably mounted in the cutter groove 10. When the cutter 8 moves in the cutter groove 10, it has a first position that is misaligned with the iron wire and a second position that cuts the iron wire. That is, the cutter 8 moves up and down in the cutter groove 10 to cut the iron wire. The wire guide seat 7 of the cutting assembly 6 is designed as a movable structure. During operation, the wire guide seat 7 is first moved to abut against the corresponding wire inlet hole of the stamping mechanism 2, and the conveying assembly 5 is activated to transport the wire. A certain length of wire is then introduced according to the design requirements. The wire is then cut by the wire assembly and withdrawn from the wire guide seat 7. This process is repeated multiple times to process multiple nails. Since the wire feeding length can be adjusted according to actual needs, there is no waste of materials, thus it has the advantages of saving consumables and reducing costs.

[0027] As attached Figure 3 and attached Figure 4 As shown, the mounting bracket 3 is provided with a guide rail 11 extending toward the stamping mechanism 2, and the wire guide seat 7 is provided with a guide groove 12 that cooperates with the guide rail 11. The cross-sectional shape of the guide rail 11 and the guide groove 12 can be T-shaped or dovetail-shaped. This design can guide the wire guide seat 7, making it oriented and move stably toward or away from the stamping mechanism 2.

[0028] As attached Figure 3 As shown, the cutting assembly 6 further includes a first motor 13, a gear 14, and a rack 15. The first motor 13 is mounted on the mounting bracket 3. The gear 14 is linked to the motor shaft of the first motor 13. The rack 15 is connected to the side of the wire guide seat 7, and the extending direction of the rack 15 is parallel to the extending direction of the guide rail 11. The gear 14 and the rack 15 are meshed together. The first motor 13 drives the wire guide seat 7 to move through the gear 14 and rack 15, which not only provides precise and stable distance control but also ensures good reliability and durability of the transmission structure.

[0029] As attached Figure 4 and attached Figure 5As shown, the cutting assembly 6 also includes a blade holder 16, a pressing force component 17, and a return spring 18. The blade holder 16 is positioned above the wire guide seat 7, and the upper end of the cutter 8 is connected to the blade holder 16. The pressing force component 17 cooperates with the blade holder 16 to apply a downward force to the blade holder 16, causing the blade holder 16 to drive the cutter 8 downward and cut the wire. The return spring 18 is positioned between the wire guide seat 7 and the blade holder 16. Positioning slots can be provided on the wire guide seat 7 and the blade holder 16 for the two ends of the return spring 18 to be embedded, or a guide post can be inserted between them. The return spring 18 is positioned around the guide post and used to return the blade holder 16 and the cutter 8 from the second position to the first position. The pressing force component 17 provides downward pressure to the cutter 8, and the return spring 18 provides upward return force to the cutter 8, thereby realizing the cutting action of the cutter 8 on the wire. The structure is simple and reliable, and easy to assemble and produce.

[0030] As attached Figure 5 As shown, the cutter 8 has a cutting hole 19 in the middle for the wire to pass through. By using a method where the cutting hole 19 is misaligned with the wire guide hole 9 to cut the wire, the cutter 8 can be longer, thus making its operation more stable and reliable.

[0031] As attached Figure 4 and attached Figure 5 As shown, the guide wire seat 7 includes an upper seat 20 and a lower seat 21 connected together by fasteners (which may be bolts). The cutter groove 10 includes an upper groove 22 on the upper seat 20 and a lower groove 23 on the lower seat 21. The cross-sectional shape of the upper groove 22 is similar to that of the cutter 8, and the cross-sectional area of ​​the lower groove 23 is larger than that of the upper groove 22. A limiting protrusion 24 is provided at the part of the cutter 8 located in the lower groove 23. When the limiting protrusion 24 moves upward and abuts against the lower end of the upper seat 20, it constitutes a limit. This design can limit the stroke of the cutter 8 during its upward return, preventing it from being pushed out by the return spring 18. At the same time, when it reaches the upper limit position, the spring force provided by the return spring 18 to the cutter 8 can ensure that it is stably located in the first position.

[0032] As attached Figure 3As shown, the pressing power component 17 includes a first cylinder 25, a rocker arm 26, and a hinge seat 27. The hinge seat 27 is mounted on the wire guide seat 7. The middle part of the rocker arm 26 is rotatably connected (via a rotating shaft) to the hinge seat 27. A drive shaft 28 is provided on the extended end of the first cylinder 25. An elongated hole 29 is provided on the end of the rocker arm 26 near the first cylinder 25. The drive shaft 28 extends into the elongated hole 29 to drive the rocker arm 26 to swing. The width of the elongated hole 29 is approximately equal to the diameter of the drive shaft 28. When the rocker arm 26 swings, the drive shaft 28 can slide relative to the rocker arm 29 along the extension direction of the elongated hole 29. A roller 30 is rotatably provided on the tool holder 16. The lower side of the end of the rocker arm 26 away from the first cylinder 25 rolls with the outer circumference of the roller 30. When the first cylinder 25 extends, the rocker arm 26 swings in the first direction and applies downward pressure to the tool holder 16. When the first cylinder 25 retracts, the rocker arm 26 swings in the second direction, and the tool holder 16 moves upward under the action of the return spring 18. The rocker arm 26 and the roller 30 on the tool holder 16 roll together, which greatly reduces the friction between the two. This not only reduces friction noise but also improves the service life of the mating parts.

[0033] As attached Figure 6 As shown, the conveying assembly 5 includes a conveying frame 31 mounted on the mounting frame 3, a first guide wheel 32 and a second guide wheel 33 rotatably mounted on the conveying frame 31, and a motor drive unit 34 located on the side of the conveying frame 31 and connected to the first guide wheel 32. The outer circumferences of the first guide wheel 32 and the second guide wheel 33 are respectively rough and smooth surfaces. The outer circumferences of the first guide wheel 32 and the second guide wheel 33 are respectively distributed with a first transmission tooth 35 and a second transmission tooth 36, which mesh with each other. The wire passes between the first guide wheel 32 and the second guide wheel 33. The motor drive unit 34 drives the first guide wheel 32 to rotate, and the first guide wheel 32 drives the second guide wheel 33 to rotate through the transmission teeth. When the two guide wheels press the wire and rotate, they drive the wire forward, realizing the transmission of the wire. The motor drive unit 34 is a combination of a motor and a transmission structure, which can be a belt drive assembly, a gear drive assembly, or a sprocket and chain drive assembly, etc.

[0034] As attached Figure 6 As shown, the upper end of the conveyor frame 31 is equipped with a second cylinder 37. Guide grooves 38 are vertically arranged on both sides of the conveyor frame 31, and bearing seats 39 are slidably arranged vertically in the guide grooves 38. The two ends of the second guide wheel 33 respectively cooperate with the corresponding bearing seats 39. The extended end of the second cylinder 37 is connected to the bearing seat 39 via a connecting rod 40 to drive the second guide wheel 33 to rise and fall. A connecting plate can be installed on the bearing seat 39, and the connecting plate is connected to the connecting rod 40. The loosening and tightening of the wire is achieved by adjusting the distance between the two guide wheels using the cylinder.
