Description

Technical Field

[0001] This utility model relates to the field of foldable card holder processing technology, and in particular to a needle-threading device for foldable card holders. Background Technology

[0002] Foldable card holders are a type of card storage product. During their production, a pin needs to be inserted between two flaps to achieve the folding connection. This is a crucial step in card holder production. Traditionally, the pin assembly relies on manual operation. Operators manually align the pin with the mounting holes on the flaps and push it in. This method is not only inefficient and unable to meet large-scale production needs, but also lacks precision, easily leading to problems such as improper pin installation. This affects the quality and lifespan of the card holder, and results in technical issues with poor needle threading efficiency and quality. Utility Model Content

[0003] Therefore, it is necessary to provide a needle-threading device for folding card holders to address the technical problems of poor needle-threading efficiency and quality.

[0004] A pin-threading device for a folding card holder is provided for pushing a pin into two flaps of the folding card holder. The device includes an assembly table, a feeding mechanism, and a pin-pushing mechanism. The assembly table has an assembly slot for placing the flaps. The feeding mechanism includes a feeding cassette, a pin carrier, and a feeding drive. The feeding cassette has a storage slot for storing the pin. The pin carrier has a pin slot and a first use position and a second use position. When the pin carrier is in the first use position, the pin slot is connected to the storage slot. When the pin carrier is in the second use position, the pin slot is connected to the assembly slot. The feeding drive drives the pin carrier to switch between the first use position and the second use position. The pin-pushing mechanism pushes the pin in the pin slot into the assembly slot.

[0005] In one embodiment, the assembly table includes a positioning member and a guide member. The positioning member is provided with the assembly groove, and the guide member is disposed between the positioning member and the needle carrier and is provided with a guide groove communicating with the assembly groove.

[0006] In one embodiment, the guide includes a fixing portion and a guiding portion, the guiding portion gradually tapering toward the mounting groove, and the guiding groove passing through the fixing portion and the guiding portion.

[0007] In one embodiment, the guide is further provided with a guide opening, which is connected to one end of the guide groove near the needle carrier and gradually expands toward the needle carrier.

[0008] In one embodiment, the feed cassette includes a cover plate and a needle cassette. The cover plate covers the side of the needle carrier near the needle carrier groove to close the needle carrier groove. The needle cassette has the storage groove, which passes through the cover plate and communicates with the needle carrier groove.

[0009] In one embodiment, the needle cartridge is further provided with an observation port, which is located on the side of the needle cartridge and communicates with the storage tank.

[0010] In one embodiment, the needle carrier groove has a connector at one end near the storage tank, and the connector gradually expands toward the storage tank.

[0011] In one embodiment, the pusher mechanism includes an adapter block, a push rod, and a pusher drive. The adapter block is connected to the push rod, and the pusher drive is used to drive the adapter block closer to or further away from the assembly table so that the push rod is pushed into the needle carrier groove by the adapter block, thereby pushing the pin in the needle carrier groove into the assembly slot.

[0012] In one embodiment, the pusher mechanism further includes a guide member having a guide hole that is slidably connected to the pusher rod.

[0013] In one embodiment, the adapter block includes a body and a fixing member. The body is connected to the push pin drive member and has a mounting hole and a fixing hole communicating with the mounting hole. The mounting hole and the fixing hole are staggered. The push rod movably passes through the mounting hole. The fixing member is threadedly connected to the fixing hole and abuts against the push rod in the mounting hole.

[0014] The beneficial effects of the folding card holder needle threading device provided in this application are as follows: by coordinating the assembly table, the feeding mechanism, and the needle pushing mechanism, automatic feeding of the pin shaft and precise insertion of the card sheet are achieved. In the first use position, the needle carrier of the feeding mechanism is connected to the storage groove to receive the pin shaft in the storage groove. In the second use position, it is connected to the assembly groove, and then the needle pushing mechanism pushes the pin shaft into the assembly groove to complete the pin shaft assembly of the folding card holder card sheet. The whole process does not require manual intervention, which greatly improves production efficiency and reduces labor costs. At the same time, through the precise coordination of each mechanism, the accuracy and stability of the pin shaft assembly are guaranteed, thereby improving the needle threading efficiency and needle threading quality of the folding card holder.

[0031] like Figure 1 As shown, it is the folding card holder needle threading device 100 of this utility model, used to push the pin into the two flaps of the folding card holder.

[0032] like Figures 1 to 3 As shown, the folding card holder needle threading device 100 includes: an assembly table 10, a feeding mechanism 20, and a needle pushing mechanism 30. The assembly table 10 has an assembly slot 111 for placing card sheets. The feeding mechanism 20 includes a feeding cassette 21, a needle carrier 22, and a feeding drive 23. The feeding cassette 21 has a storage slot 211 for storing pins. The needle carrier 22 has a needle slot 221 and a first usage position and a second usage position. When the needle carrier 22 is in the first usage position, the needle slot 221 communicates with the storage slot 211. When the needle carrier 22 is in the second usage position, the needle slot 221 communicates with the assembly slot 111. The feeding drive 23 drives the needle carrier 22 to switch between the first and second usage positions. Mechanism 30 is used to push the pin in the needle slot 221 into the assembly slot 111. With the cooperation of the assembly table 10, the feeding mechanism 20 and the needle pushing mechanism 30, the automatic feeding of the pin and the precise pushing of the page are realized. The needle carrier 22 of the feeding mechanism 20 is connected to the storage slot 211 in the first use position and can receive the pin in the storage slot 211. In the second use position, it is connected to the assembly slot 111 and then the pin is pushed into the assembly slot 111 by the needle pushing mechanism 30 to complete the pin assembly of the folding card holder page. The whole process does not require manual intervention, which greatly improves production efficiency and reduces labor costs. At the same time, the precise cooperation of each mechanism ensures the accuracy and stability of the pin assembly, thereby improving the needle threading efficiency and needle threading quality of the folding card holder.

[0033] The following text, combined with Figures 1 to 5 The above-mentioned folding card holder needle-threading device 100 will be further described.

[0034] like Figures 2 to 3As shown, the assembly table 10 includes a positioning component 11 and a guide component 12. The positioning component 11 is provided with an assembly groove 111. The guide component 12 is disposed between the positioning component 11 and the needle carrier 22, and is provided with a guide groove 121 that communicates with the assembly groove 111. The guide groove 121 provides a guiding path for the pin to be transported from the needle carrier 22 to the assembly groove 111, ensuring that the pin can accurately enter the leaf piece in the assembly groove 111 from the needle carrier groove 221, avoiding the pin from shifting during the insertion of the leaf piece. At the same time, the positioning component 11 positions the leaf piece, ensuring that the position of the leaf piece is fixed during the assembly process, which facilitates the accurate insertion of the pin into the mounting hole 312 of the leaf piece, thereby improving the insertion accuracy of the pin.

[0035] To improve the smoothness of pin conveying, such as Figure 2 As shown, the guide 12 includes a fixing part 122 and a guiding part 123. The guiding part 123 gradually contracts towards the assembly groove 111, and the guiding groove 121 passes through the fixing part 122 and the guiding part 123. The contraction structure of the guiding part 123 forms a guide slope, so that the guiding part 123 can be directly inserted into the hole of the blade. When the pin enters the guiding groove 121 from the needle carrier 22, the contracted guiding part 123 can guide and calibrate the pin, making it easier for the pin to slide smoothly along the guiding groove 121 into the hole of the blade in the assembly groove 111. This effectively reduces the jamming phenomenon of the pin in the assembly groove 111 and improves the smoothness of the pin conveying.

[0036] like Figure 3 As shown, the guide 12 is also provided with a guide opening 124. The guide opening 124 is connected to the end of the guide groove 121 near the needle carrier 22 and gradually expands towards the needle carrier 22. The enlarged structure of the guide opening 124 facilitates the smooth entry of the pin in the needle carrier groove 221 into the guide groove 121. Even if there is a certain positional deviation between the needle carrier 22 and the guide 12, the enlarged guide opening 124 can still play a guiding role, ensuring that the pin can accurately enter the guide opening 124 from the needle carrier groove 221 and then enter the guide groove 121, thereby improving the fault tolerance and reliability of the needle threading device.

[0037] To improve the feeding stability and reliability of the feeding mechanism 20, such as Figure 4 As shown, the feeding cassette 21 includes a cover plate 212 and a needle cassette 213. The cover plate 212 covers the side of the needle carrier 22 near the needle carrier groove 221 to close the needle carrier groove 221. The needle cassette 213 is provided with a storage trough 211. The storage trough 211 passes through the cover plate 212 and communicates with the needle carrier groove 221. The cover plate 212 can prevent the pin from falling out of the needle carrier groove 221 during the movement of the needle carrier 22, ensuring the stable storage and conveying of the pin in the needle carrier groove 221. The storage trough 211 communicates with the needle carrier groove 221, so that the pin can smoothly enter the needle carrier groove 221 from the storage trough 211, thereby improving the feeding stability and reliability of the feeding mechanism 20.

[0038] To improve the continuity of the production process, such as Figure 4 As shown, the needle box 213 is also provided with an observation port 214. The observation port 214 is located on the side of the needle box 213 and is connected to the storage tank 211. The setting of the observation port 214 makes it convenient for operators to observe the amount of pins stored in the storage tank 211 in real time, replenish the pins in time, avoid production interruption due to insufficient storage, and achieve the purpose of improving the continuity of the production process.

[0039] To improve the success rate of pin loading, such as Figure 4 As shown, the pin carrier groove 221 has a receiving port 222 at one end near the storage tank 211. The receiving port 222 gradually expands towards the storage tank 211. The expanded structure of the receiving port 222 can more conveniently receive the pins in the storage tank 211. Even if there is a certain positional error between the storage tank 211 and the pin carrier groove 221, the expanded receiving port 222 can ensure that the pins can smoothly enter the pin carrier groove 221, thereby improving the success rate of pin feeding.

[0040] like Figure 5 As shown, the push pin mechanism 30 includes an adapter block 31, a push rod 32, and a push pin drive component 33. The adapter block 31 is connected to the push rod 32. The push pin drive component 33 is used to drive the adapter block 31 to move closer to or further away from the assembly table 10, so that the push rod 32 can be pushed into the needle carrier groove 221 through the adapter block 31, thereby pushing the pin in the needle carrier groove 221 into the assembly groove 111. The push pin drive component 33 is a cylinder. The push pin drive component 33 drives the push rod 32 to move through the adapter block 31, which can accurately control the pushing stroke of the push rod 32, ensuring that the pin can be pushed into the assembly groove 111 stably and accurately, avoiding the situation where the pin is not installed properly, and achieving the purpose of improving the quality of pin assembly.

[0041] To improve the assembly accuracy and stability of the pin, such as Figure 5 As shown, the push pin mechanism 30 also includes a guide member 34. The guide member 34 is provided with a guide hole 341 that is slidably connected to the push rod 32. The guide hole 341 guides the movement of the push rod 32, ensuring that the push rod 32 moves in a straight line during the push process and avoiding the push rod 32 from deflecting. This ensures that the pin can be pushed into the assembly groove 111 in the correct direction, thereby improving the assembly accuracy and assembly stability of the pin.

[0042] To improve the versatility and adjustability of the needle-threading device, such as Figure 5As shown, the adapter block 31 includes a body 311 and a fixing member (not shown). The body 311 is connected to the pusher drive member 33 and is provided with a mounting hole 312 and a fixing hole 313 that communicates with the mounting hole 312. The mounting hole 312 and the fixing hole 313 are staggered. The pusher 32 is movably passed through the mounting hole 312. The fixing member is threadedly connected to the fixing hole 313 and abuts against the pusher 32 in the mounting hole 312. The position of the pusher 32 in the mounting hole 312 can be easily adjusted by the fixing member to adapt to different specifications of pins and assembly requirements, thereby improving the versatility and adjustability of the needle threading device.

[0043] When using the folding card holder needle threading device 100 provided in this application: First, the two pages of the folding card holder are placed together in the assembly groove 111 of the positioning member 11 of the assembly table 10. The positioning member 111 is positioned by the assembly groove 111. The feeding drive member 23 drives the needle carrier member 22 to the first use position. The pin in the storage groove 211 falls into the needle carrier groove 221 through the guide port 222. Then, the feeding drive member 23 drives the needle carrier member 22 to switch to the second use position, so that the needle carrier groove 221 is connected to the guide groove 121. Next, the pusher drive member 33 drives the adapter block 31 to approach the assembly table 10. The push rod 32 is inserted into the needle carrier groove 221 under the guidance of the guide member 34. The pin is pushed into the assembly groove 111 through the guide groove 121 of the guide member 12, so that the pin passes through the mounting hole 312 of the page, and the assembly is completed.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
