[0048] Please see below. Figures 1-4 The paper tray threading workbench provided in this embodiment of the utility model specifically includes:

[0049] The cable threading base 10 has a base through hole 11 in the middle;

[0050] The wire threading module 20 is mounted on the wire threading base 10 and includes a fixed module 21 and a movable module 22. A paper tray 30 is attached above the fixed module 21 and the movable module 22. The paper tray 30 is provided with an inlet hole 31 and an outlet hole 32. The fixed module 21 and the movable module 22 together form a module through hole 23 that connects to the through hole 11 of the base and a wire through hole 24. The two ends of the wire through hole 24 are respectively connected to the inlet hole 31 and the outlet hole 32.

[0051] The elastic mechanism 40 is disposed on the side of the moving module 22 and is used to drive the moving module 22 to close around one end of the fixed module 21.

[0052] The ejector mechanism 50 is located below the wire-threading base 10. It extends the ejector pin 51, passes through the base through hole 11, inserts it into the module through hole 23, and separates the enclosed fixed module 21 and movable module 22.

[0053] In this embodiment, driven by the elastic mechanism 50, the moving module 22 tightly fits against the fixed module 21 (e.g., Figure 5 As shown), and together they form a through hole 24. Based on this, the thread 60 passes through the inlet hole 31, and is guided through the through hole 24 to the outlet hole 32, thus threading the paper tray 30. Then, the ejector mechanism 50 extends the ejector pin 51, passes through the base through hole 11, and inserts it into the module through hole 23 to separate the enclosed fixed module 21 and moving module 22 (as shown). Figure 6 As shown, the thread 60 can be pulled out from the thread hole 24, so that the paper tray 30 with the thread 60 can be easily taken out, making it easy to replace the paper tray 30. This improves the efficiency of threading the paper tray 30 and simplifies the operation process, ensuring that the paper tray 30 can complete the threading task stably and conveniently.

[0054] In one embodiment, the diameter of the port of the through hole connecting to the inlet hole 31 is larger than the diameter of the port of the outlet hole 32. This embodiment designs the inlet diameter of the through hole 24 to be larger, allowing the wire 60 to enter the through hole 24 more smoothly and reducing wire jamming. At the same time, the smaller outlet hole 32 ensures that the wire is taut, improving threading accuracy and stability.

[0055] In one embodiment, the fixing module 21 includes a first fixing module 211 and a second fixing module 212, the moving module 22 includes a first moving module 221 and a second moving module 222, and the paper tray is provided with two sets of inlet holes 31 and outlet holes 32.

[0056] The first fixed module 211, the first moving module 221, the second fixed module 212, and the second moving module 222 are sequentially joined to form a module through hole 23. The first moving module 221 and the second fixed module 212 are attached to form a first through hole 241. The second fixed module 212 and the second moving module 222 are attached to form a second through hole 242. The first through hole 241 and the second through hole 242 are respectively connected to two sets of inlet holes 31 and outlet holes 32 on the paper tray.

[0057] In this embodiment, the first fixing module 211, the first moving module 221, the second fixing module 212, and the second moving module 222 are sequentially arranged to form the first threading hole 241 and the second threading hole 242. This allows the first threading hole 241 and the second threading hole 242 to guide the two sets of threads to be threaded independently, thereby improving threading efficiency, ensuring that each set of threads passes through the paper tray stably and accurately, further optimizing the operation process, reducing errors in the threading process, and improving the overall threading quality.

[0058] Combination Figure 7As shown, in one embodiment, the first moving module 221 has a first through groove 2211 on the side that is attached to the second fixing module 212, and the corresponding attaching surface of the second fixing module 212 has a first matching groove 2121. The first through groove 2211 and the first matching groove 2121 together form a first through hole 241.

[0059] The second moving module 222 has a second through groove on the side that is attached to the second fixed module 212, and the corresponding contact surface of the second fixed module 212 has a second matching groove. The second through groove and the second matching groove together form a second through hole 242.

[0060] In this embodiment, by providing a through-hole and a matching groove between the first moving module 221 and the second fixing module 212, a first through-hole 241 is formed when the second moving module 222 and the second fixing module 212 are in contact, serving as a precise through-hole to ensure the thread remains stable during threading, reducing friction and thread jamming, and improving threading efficiency. Similarly, a through-hole and a matching groove are also provided between the second moving module 222 and the second fixing module 212, forming a second through-hole 242 when the second moving module 222 and the second fixing module 212 are in contact.

[0061] Combination Figures 8-10 As shown, in one embodiment, the first fixing module 211 extends outward from both sides to form a first protruding limiting portion 2111 and a second protruding limiting portion 2112, respectively. The first moving module 221 is installed between the first protruding limiting portion 2111 and the second fixing module 212, and the second moving module 222 is installed between the second protruding limiting portion 2112 and the second fixing module 212.

[0062] In this embodiment, by setting the first protruding limiting part 2111 and the second protruding limiting part 2112, the movement range of the first moving module 221 and the second moving module 222 can be effectively limited, ensuring that they maintain a precise position during the process of the elastic mechanism driving the closing and the pin mechanism 50 driving the opening, preventing the movement from exceeding the expected range, thereby ensuring the stability and accuracy of the threading operation, reducing operational errors, and improving the overall threading efficiency and quality.

[0063] In one embodiment, the elastic mechanism includes a first elastic mechanism 41 and a second elastic mechanism;

[0064] The first elastic mechanism 41 is disposed between the first protruding limiting part 2111 and the first moving module 221, and is used to push the first moving module 221 to fit with the second fixed module 212.

[0065] The second elastic mechanism is disposed between the second protruding limiting part 2112 and the second moving module 222, and is used to push the second moving module 222 to fit against the second fixed module 212.

[0066] In this embodiment, through the synergistic effect of the first elastic mechanism 41 and the second elastic mechanism, the first moving module 221 and the second moving module 222 are ensured to fit tightly against the second fixed module 212 during the enclosing process, forming a stable first wire hole 241 and second wire hole 242, thereby providing a precise wire passage and improving the wire threading efficiency.

[0067] In one embodiment, the first protruding limiting part 2111 is provided with a first mounting hole 2113 on the side facing the first moving module 221, and the first moving module 221 is provided with a corresponding second mounting hole 2212 on the side facing the first protruding limiting part 2111. The two ends of the first elastic mechanism 41 are respectively installed in the first mounting hole 2113 and the second mounting hole 2212.

[0068] The second protruding limiting part 2112 is provided with a third mounting hole on the side facing the second moving module 222, and the second moving module 222 is provided with a corresponding fourth mounting hole on the side facing the second protruding limiting part 2112. The two ends of the second elastic mechanism are respectively installed in the third mounting hole and the fourth mounting hole.

[0069] In this embodiment, by providing corresponding first mounting holes 2113 and second mounting holes 2212 on the first protruding limiting portion 2111 and the first moving module 221 respectively, and installing both ends of the first elastic mechanism 41 into the mounting holes, using the first mounting hole 2113 at one end of the first protruding limiting portion 2111 as a fixing point, and connecting the other end to the first moving module 221 through the second mounting hole 2212, it is ensured that the first elastic mechanism 41 can provide stable elastic force when pushing the first moving module 221, ensuring its precise fit against the second fixing module 212. Similarly, by providing corresponding third and fourth mounting holes between the second protruding limiting portion 2112 and the second moving module 222 respectively, the stable function of the second elastic mechanism is ensured, further enhancing the stability of the overall structure and the accuracy of the threading operation.

[0070] In one embodiment, the first elastic mechanism 41 includes a first mounting shaft 411 and a first spring 412. The two ends of the first mounting shaft 411 are respectively mounted in the first mounting hole 2113 and the second mounting hole 2212, and the first spring 412 is sleeved on the first mounting shaft 411.

[0071] The second elastic mechanism includes a second mounting shaft and a second spring. The two ends of the second mounting shaft are respectively installed in the third mounting hole and the fourth mounting hole, and the second spring is sleeved on the second mounting shaft.

[0072] In this embodiment, by setting a first spring 412 sleeved on the first mounting shaft 411 and fixing its two ends in the first mounting hole 2113 and the second mounting hole 2212 respectively, the first spring 412 can uniformly transmit elastic force along the first mounting shaft 411 during the extension and retraction process, ensuring accurate elastic force direction and improving the fitting accuracy of the first moving module 221. Similarly, a second spring sleeved on the second mounting shaft and fixed at both ends in the third mounting hole and the fourth mounting hole ensures that the second moving module 222 accurately fits the second fixed module 212 under the action of elastic force, further optimizing the stability of the wire passage and the wire threading efficiency. In other embodiments, the elastic mechanism can also adopt other types of elastic elements according to different actual application scenarios, such as rubber pads or piston rods, etc.

[0073] In one embodiment, the threading base 10 is provided with screw holes, and the fixing module is fixed to the threading base 10 by screws engaging with the screw holes.

[0074] In this embodiment, the fixing module can be firmly installed on the cable-threading base 10 through the tight fit between the screw and the screw hole, ensuring the stability of the overall structure. In other embodiments, other fixing methods can also be used, such as clips, adhesives, welding, or magnetic attraction, to adapt to different application requirements.

[0075] In one embodiment, the ejector mechanism 50 includes an ejector pin and a cylinder 52. The ejector pin is connected to the output end of the cylinder 52. The cylinder 52 is used to drive the ejector pin 51 to reciprocate in the vertical direction. The ejector pin 51 can pass through the base through hole 11 and be inserted into the module through hole 23.

[0076] In this embodiment, through the precise control of the cylinder 52, the ejector pin 51 can reciprocate stably in the vertical direction, thereby passing through the base through hole 11 and inserting into the module through hole 23 to separate the enclosed fixed module 21 and moving module 22. After the thread 60 is threaded and the paper tray 30 is successfully removed, the ejector pin mechanism 50 retracts the ejector pin 51, allowing the moving module 22 to quickly return to its initial position with the assistance of the elastic mechanism 40, preparing for the next threading operation. This not only ensures the continuity and efficiency of the threading process, but also reduces the labor intensity of the operator and improves the overall automation level of the operation.
