Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0051] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0052] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0053] Please see below. Figure 1 and Figure 2 The present invention provides a paper tray threading device, which specifically includes:

[0054] The threading workbench 10 has a paper tray 20 attached above it. The paper tray 20 is provided with a wire inlet hole 21 and a wire outlet hole 22. The threading workbench 10 is used to guide the wire through the wire inlet hole 21 and the wire outlet hole 22 in sequence for threading.

[0055] The threading unit 30 is disposed above the threading workbench 10 and is used to feed the thread to the threading workbench 10 through a clamp for threading.

[0056] The wire cutting unit 40 is located on the side of the threading workbench 10 and is used to cut off excess thread after threading is completed.

[0057] In this embodiment, by setting up a threading workbench 10 to overlap the paper tray 20, and by using a threading unit 30 to guide the thread to the threading workbench 10, the thread passes sequentially through the inlet hole 21 and the outlet hole 22 under the guidance of the threading workbench 10. Then, the excess thread is cut off by the thread cutting unit 40 to prepare for threading the next paper tray 20. This improves the automation level and accuracy of threading the paper tray 20, reduces human error, optimizes the production process, reduces labor intensity, and improves overall production efficiency.

[0058] In specific application scenarios, such as Figure 2 As shown, after the thread 23 passes through the inlet hole 21 and outlet hole 22 of the paper tray 20 in sequence, a portion of the thread 23 outside the inlet hole 21 needs to be left and then cut off in order to carry out the subsequent processing of the paper tray 20, and to release the thread 23 to carry out the threading work of the next paper tray 20.

[0059] Furthermore, in this embodiment, the two parts of the threading workbench 10 can be closed together to form a guide channel under the drive of the corresponding drive components. The two ends of the guide channel are respectively connected to the inlet hole 21 and the outlet hole 22, so that the thread can smoothly enter the outlet hole 22 from the inlet hole 21 under the guidance of the guide channel. Then, the drive components drive the two parts of the threading workbench 10 to separate to form a gap, so that the threaded thread can be taken out from the gap to cooperate with the thread cutting unit 40 to remove the paper tray 20 for subsequent work. After the threaded paper tray 20 is removed, the threading workbench 10 closes again and overlaps the next paper tray 20 for threading operation, and so on. The specific structure of the threading workbench 10 is not the focus of this embodiment, so its detailed structure will not be described in detail.

[0060] Combination Figure 3 As shown, in one embodiment, the threading unit 30 is fixed to the mounting platform 50 by a support plate 31. A thread feeding mechanism 32 is provided on one side of the support plate 31, and a thread roll 33 for storing the thread is provided on the other side. The thread on the thread roll 33 is fed into the threading workbench 10 by the clamp on the thread feeding mechanism 32 for threading.

[0061] In this embodiment, a wire spool 33 is provided on one side of the support plate 31 to store the wire, and a wire feeding mechanism 32 is provided on the other side. The wire feeding mechanism 32 drags the wire through a clamp, and the wire spool 33 rotates accordingly, thereby feeding the wire into the threading workbench 10, ensuring that the wire moves smoothly in the guide channel, reducing the risk of wire jamming, and improving threading efficiency.

[0062] Combination Figure 4 As shown, in one embodiment, the wire feeding mechanism 32 includes a fixed clamp 321, a movable clamp 322 and a wire cutting clamp 323 arranged sequentially from top to bottom;

[0063] The movable clamp 322 is connected to the support plate 31 via the clamp drive assembly 324, and is used to move vertically under the drive of the clamp drive assembly 324, and cooperate with the fixed clamp 321 to convey the wire to the threading worktable 10.

[0064] The wire cutting clamp 323 is used to clamp the wire extending from the wire outlet 22 and, together with the movable clamp 322, tighten the wire onto the paper tray 20.

[0065] In this embodiment, the wire feeding mechanism 32, through the coordinated action of the moving clamp 322 and the fixed clamp 321, feeds the wire to the threading workbench 10 for threading, and clamps the wire extending from the wire outlet hole 22 with the wire cutting clamp 323, and finally tightens the wire onto the paper tray 20 with the moving clamp 322.

[0066] Specifically, during the feeding process, the thread is first held by the fixed clamp 321. Then, the movable clamp 322, driven by the clamp drive assembly 324, moves vertically upward to below the fixed clamp 321 and clamps the thread. The fixed clamp 321 then releases, and the clamp drive assembly 324 drives the movable clamp 322 downward, simultaneously dragging the thread downward into the threading worktable 10 for threading. After threading, the thread-cutting clamp 323 clamps the thread extending out of the exit hole 22, and the movable clamp 322 moves upward again to tighten the thread, ensuring the thread on the paper tray 20 is firmly fixed. At this point, the thread-cutting unit 40 performs the cutting operation, completing the entire threading process. It can be understood that after completing the threading operation of the previous paper tray 20, the fixed clamp 321 re-clamps the thread, and the movable clamp 322 moves upward again to below the fixed clamp 321 to clamp the thread, repeating the above steps to ensure smooth threading of the new paper tray 20. This cyclical operation not only improves threading efficiency but also reduces the possibility of thread jamming, ensuring the stability and reliability of the entire threading process.

[0067] In one embodiment, the wire feeding mechanism 32 further includes:

[0068] Transition wheel assembly 325 is used to guide the thread on the thread spool 33 for threading;

[0069] The slide bar assembly 326 is connected to the lower end of the transition wheel assembly 325 and extends vertically downward;

[0070] The fixed sleeve seat 327 is fixedly sleeved on the slide rod assembly 326 and is used to support the fixed clamp 321.

[0071] The movable sleeve seat 328 is slidably sleeved on the slide rod group 326 and connected to the clamp drive assembly 324, which is used to drive the movable clamp 322 to slide along the slide rod group 326.

[0072] The connecting plate 329 is fixed to the lower end of the slide bar assembly 326 and connected to the support plate 31, and is used to support the slide bar assembly 326 and the wire cutting clamp 323.

[0073] In this embodiment, the transition wheel assembly 325 guides the thread on the thread roll 33, ensuring that the thread smoothly enters the threading workbench 10; the slide bar assembly 326 provides a stable sliding path, and the fixed sleeve seat 327 supports the fixed clamp 321, ensuring its stable positioning; the movable sleeve seat 328 drives the movable clamp 322 to slide along the slide bar assembly 326 under the drive of the clamp drive assembly 324, thereby controlling the thread conveying by the synergistic effect of the fixed clamp 321 and the movable clamp 322; the connecting plate 329 fixes the slide bar assembly 326 to ensure the stability of the overall structure, and fixes the thread cutting clamp 323 to clamp the thread for cutting. The coordinated work of each component ensures that the thread is accurately aligned during the threading process, which can reduce errors and improve threading efficiency and thread stability.

[0074] Combination Figure 5 As shown, in one specific embodiment, the transition wheel assembly 325 is provided with multiple rotatable transition wheels, and the transition wheels are provided with grooves to accommodate threads of different diameters, ensuring that the threads do not deviate from the track during the threading process. The flexible design of the transition wheel assembly 325 optimizes the thread guiding effect and improves the flexibility, accuracy and stability of the overall threading system.

[0075] In specific application scenarios, the number of components in the thread feeding mechanism 32 and the number of thread rolls 33 can be adjusted according to actual needs to ensure the flexibility and adaptability of the threading process.

[0076] For example, when the paper tray 20 is provided with two sets of inlet holes 21 and outlet holes 22, that is, when two sets of wires need to be threaded, two wire rolls 33 can be set, and an appropriate number of transition wheels can be set on the transition wheel group 325, as well as two sets of fixed clamps 321 and movable clamps 322, to perform independent threading operations for the two sets of wires respectively, thereby matching the threading requirements of the two sets of wires.

[0077] In addition, hollow wire guide rods can be installed on the fixed sleeve seat 327 and the movable sleeve seat 328. The upper and lower ends of the guide rods are connected to the transition wheel group 325 and the connecting plate 329, respectively. The wires pass smoothly along the guide rods, ensuring precise alignment of the wires and improving the accuracy of threading.

[0078] Based on this, a fixed clamp 321 containing a pressure head and a pressure head cylinder can be used. The pressure head cylinder drives the pressure head to press the guide rod against the side of the fixed sleeve seat 327, thereby clamping the wire. Similarly, the movable clamp 322 can also be equipped with a corresponding pressure head and a pressure head cylinder, and the pressure head cylinder drives the pressure head to clamp the wire for dragging. Of course, depending on actual needs, it is also possible to choose not to set a guide rod and directly press the wire against the sides of the fixed sleeve seat 327 and the movable sleeve seat 328.

[0079] Alternatively, the fixed sleeve seat 327 can be configured as an I-shaped or L-shaped structure, forming a sleeve seat groove. The corresponding fixing clamp 321 can be designed to match the shape of the sleeve seat groove, and guide holes can be provided at the protruding arm ends of the I-shaped or L-shaped structure to facilitate precise threading. The thread is guided through the sleeve seat groove by the guide holes, and then the pressure head is driven by the pressure head cylinder to press the thread tightly against the side of the sleeve seat groove, ensuring that the thread is stable and does not shift during the threading process, further improving threading efficiency and accuracy. Similarly, the movable sleeve seat 328 and the movable clamp 322 can also be configured in the same way as the fixed sleeve seat 327 and the fixing clamp 321.

[0080] In one embodiment, the clamp drive assembly 324 includes:

[0081] A fixing plate 3241 is set on the supporting upright plate 31 and fixedly connected to the connecting plate 329. A vertical slide rail 3242 is provided on the surface of the fixing plate 3241.

[0082] Synchronous pulley set 3243 is vertically mounted on fixed plate 3241 and located on the side of vertical slide rail 3242. Synchronous pulley set 3243 includes synchronous belt 3244 and synchronous motor for driving synchronous belt 3244.

[0083] The synchronous slider 3245 is slidably connected to the vertical slide rail 3242 and fixed to the synchronous belt 3244 by a pressure plate, and is also fixedly connected to the moving clamp 322.

[0084] In this embodiment, a synchronous motor drives a synchronous belt 3244, which in turn drives a synchronous slider 3245 to move up and down along a vertical slide rail 3242, thereby achieving precise movement of the moving clamp 322 and ensuring accurate alignment of the thread during the threading process.

[0085] In one embodiment, an upper limit sensor 3246 and a lower limit sensor 3247 are respectively provided on the upper and lower sides of the vertical slide rail 3242 to detect the extreme positions of the travel of the synchronous slider 3245.

[0086] The synchronous slider 3245 is equipped with a sensing plate 3248, which is used to trigger the upper limit sensor 3246 and the lower limit sensor 3247.

[0087] In this embodiment, by setting a sensing plate 3248 on the synchronous slider 3245 and configuring sensors at the upper and lower ends of the vertical slide rail 3242, the movement range of the synchronous slider 3245 is ensured to be precise and controllable. When the synchronous slider 3245 moves to the limit position, the sensing plate 3248 triggers the corresponding sensor, and the sensor immediately sends a stop signal to the synchronous motor to prevent the synchronous slider 3245 from exceeding the stroke range and ensure the safe and stable operation of the equipment.

[0088] Combination Figure 6 As shown, in one embodiment, a pressure plate 3291 is provided at the lower end of the connecting plate 329. The pressure plate 3291 is used to press the paper tray 20 onto the threading workbench 10 for threading.

[0089] The pressure plate 3291 is provided with a pressure plate inlet hole 3292 and a pressure plate outlet hole 3293. The pressure plate inlet hole 3292 and the pressure plate outlet hole 3293 are aligned with the inlet hole 21 and the outlet hole 22 on the paper tray 20, respectively. The pressure plate outlet hole 3293 is located below the wire cutting clamp 323. The pressure plate inlet hole 3292 is used to guide the wire into the paper tray 20, and the pressure plate outlet hole 3293 is used to guide the wire out and be clamped by the wire cutting clamp 323.

[0090] In this embodiment, the pressure plate 3291 ensures the stability of the thread during the threading process by pressing the paper tray 20. The inlet hole and outlet hole 22 on the pressure plate 3291 are aligned with the inlet hole 21 and outlet hole 22 of the paper tray 20, respectively, to ensure accurate thread introduction and output. After the thread passes through the outlet hole 3293 of the pressure plate, the thread is clamped by the thread cutting clamp 323, thereby tightening the thread using the moving clamp 322 and cutting off the excess thread using the thread cutting unit 40, thus completing the threading work of the paper tray 20.

[0091] In a specific embodiment, the wire cutting clamp 323 can be composed of a cylinder and two pneumatic clamps connected to the cylinder. The pneumatic clamps are positioned above the wire outlet hole 3293 of the pressure plate. After the wire passes through the wire outlet hole 3293 of the pressure plate, the cylinder drives the two pneumatic clamps to clamp the wire, ensuring that the wire does not loosen during the cutting process.

[0092] Combination Figure 7 As shown, in one embodiment, the wire cutting unit 40 includes a pneumatic scissors 41, a wire cutting drive mechanism 42, and a wire cutting fixing seat 43. The pneumatic scissors 41 is fixed to the wire cutting fixing seat 43 by the wire cutting drive mechanism 42, and the wire cutting fixing seat 43 is fixed to the mounting platform 50.

[0093] The wire-cutting drive mechanism 42 is used to drive the pneumatic scissors 41 to move closer to or further away from the threading workbench 10 to cut the wire.

[0094] In this embodiment, the wire-cutting drive mechanism 42 is fixed to the mounting platform 50 by the wire-cutting fixing seat 43, and drives the mounted pneumatic scissors 41 to move precisely, ensuring accurate wire-cutting position. Under the control of the wire-cutting drive mechanism 42, the pneumatic scissors 41 can quickly approach the threading workbench 10, cut off excess wire, and then move away from the workbench to avoid interfering with subsequent operations.

[0095] In specific application scenarios, the wire-cutting drive mechanism 42 may include components such as a wire-cutting slide rail, a wire-cutting slider, and a wire-cutting drive motor. By setting the wire-cutting slider to slide along the wire-cutting slide rail, and the wire-cutting drive motor driving the wire-cutting slider to move, the position of the pneumatic shears 41 can be precisely controlled. It is understood that since the thread is threaded vertically, to avoid interference during wire cutting and to ensure cutting accuracy, the wire-cutting slide rail can be set horizontally. This ensures that the pneumatic shears 41 does not affect the vertical threading operation during horizontal movement, while also ensuring cutting accuracy and improving cutting efficiency.

[0096] Combination Figure 8 As shown, in one embodiment, the wire-cutting unit 40 further includes a vertical fine-tuning mechanism 44, a right-angle seat 45, and a horizontal fine-tuning mechanism 46;

[0097] The horizontal fine-tuning mechanism 46 is mounted on the wire cutting fixing seat 43 and supports the right angle seat 45, and is used to adjust the horizontal position of the pneumatic scissors 41.

[0098] The vertical fine-tuning mechanism 44 is mounted on the side of the right-angle base 45 and supports the wire cutting drive mechanism 42, which is used for the vertical position of the pneumatic scissors 41.

[0099] In this embodiment, by setting a vertical fine-tuning mechanism 44 and a horizontal fine-tuning mechanism 46 connected to the thread-cutting drive mechanism 42, the horizontal and vertical positions of the pneumatic scissors 41 can be finely adjusted while the movement of the pneumatic scissors 41 is controlled by the thread-cutting drive mechanism 42. This ensures the accuracy and stability of the thread-cutting operation, further improving threading efficiency and the quality of the finished paper tray 20. In addition, the connection and fixation of the right-angle bracket 45 can also improve the overall structural stability of the thread-cutting unit 40 and reduce thread-cutting errors.

[0100] In specific applications, the fine-tuning mechanism can include components such as a fine-tuning screw, a locking nut, and an adjusting knob. The adjusting knob controls the rotation of the fine-tuning screw, which in turn moves the locking nut, thereby adjusting the minute position of the pneumatic shears 41 to ensure wire-cutting accuracy. Furthermore, scale lines and pointers can be added to the side of the fine-tuning mechanism to allow the operator to visually read and adjust the position, further optimizing the precision and consistency of the wire-cutting operation and ensuring product quality.

[0101] In one embodiment, the paper tray threading device further includes a turntable 60, which is fixed to the mounting platform 50 by a rotating mechanism 61. Multiple threading worktables 10 are arranged in a circular array on the turntable 60.

[0102] In this embodiment, the turntable 60 is driven by the rotation mechanism 61, causing multiple threading workstations 10 arranged in a circular array to sequentially enter their working positions. These workstations, in conjunction with the threading unit 30 and the wire-cutting unit 40, perform continuous threading and cutting operations, thereby achieving automated assembly line operation and improving overall production efficiency. In specific application scenarios, multiple sets of threading units 30 and wire-cutting units 40 can be set up next to the turntable 60 to achieve multi-station synchronous operation, further improving production efficiency.
