[0044] like Figure 1-6 As shown, a zipper pull rope knotting device includes:

[0045] A base 100 with a working platform 101 on the top;

[0046] A sliding seat 200 is slidably mounted in the base 100;

[0047] A telescopic clamp 300 is fixed on the sliding seat 200 , and a clamping portion 301 of the telescopic clamp 300 penetrates the working platform 101 ;

[0048] A lifting cylinder 400 is connected to the telescopic clamp 300 through a connecting rod device, and the lifting cylinder 400 is used to drive the opening and closing of the telescopic clamp 300 and the reciprocating motion of the sliding seat 200;

[0049] A winding device is rotatably mounted on the working platform 101 with the clamping portion 301 of the telescopic clamp 300 as the center of the circle;

[0050] The rope winding drive device 600 is used to drive the winding device to rotate;

[0051] The chain head fixing device 700 is fixed on the working platform 101, and the chain head fixing device 700 is used to fix the chain head. The zipper head passing through the rope is fixed by the chain head fixing device 700, and the lifting cylinder 400 is inflated to drive the telescopic clamp 300 to open, and the end of the rope is placed in the telescopic clamp 300. The lifting cylinder 400 is deflated in the first stage to drive the telescopic clamp 300 to clamp the rope, and the rope winding drive device drives the winding device to wind, and then the lifting cylinder 400 is deflated in the second stage. While driving the telescopic clamp 300 to clamp the rope, the telescopic clamp 300 is driven to move downward to pull the rope. While completing the rope knotting, the rope is also pulled to effectively prevent the rope from loosening. Through the cooperation of the sliding seat 200, the telescopic clamp 300, the lifting cylinder 400, the winding device and the rope winding drive device 600, the automatic winding and knotting of the rope is simple to operate, which reduces the labor intensity of manual labor and improves production efficiency.

[0052] In this embodiment, the winding device includes a positioning shaft and a rotating sleeve 500;

[0053] The positioning shaft is fixed on the working platform 101, and a through hole is provided in the middle of the positioning shaft for the telescopic clamp 300 to pass through and open;

[0054] The rotating sleeve 500 is sleeved on the periphery of the positioning shaft, and a winding paddle 501 for driving the telescopic winding is provided on the rotating sleeve 500. The positioning shaft is used to position the rotating sleeve 500, and the rope winding driving device 600 drives the rotating sleeve 500 to rotate, and the winding paddle 501 on the rotating sleeve 500 drives the rope to rotate to complete the winding.

[0055] In this embodiment, a layered notch is provided at the edge of the winding paddle 501. In order to prevent the rope from winding up and down during the winding process, the rope is fixed by the layered notch on the winding paddle 501, and the rope is layered and smoothed to avoid overlapping winding.

[0056] In this embodiment, the rope winding drive device 600 drives the rotating sleeve 500 to rotate through the transmission belt 601. The rotating sleeve 500 is sleeved on the periphery of the positioning shaft, and the rope winding drive device 600 is meshed with the periphery of the rotating sleeve 500 through the transmission belt 601. Compared with the gear meshing transmission, the transmission distance of the transmission belt 601 is longer, and there is a certain distance between the rope winding drive device 600 and the winding device, and there will be no interference with each other.

[0057] In this embodiment, the rope winding drive device 600 includes a hand crank, which is manually driven to drive the rotating sleeve 500 of the winding device through a transmission belt 601.

[0058] In another implementation case, the rope winding drive device 600 includes a rotating motor, which is controlled by a foot switch. Compared with the manual drive of a hand crank, the rotating motor is more labor-saving. However, because the rope is generally short and the motor rotates quickly, it is inconvenient to control and the cost is high.

[0059] In this implementation case, a dust cover 102 is provided above the working platform 101;

[0060] The top of the dust cover 102 is provided with a window 103 for the telescopic clamp 300 to pass through. The winding device is driven to rotate by the rope winding drive device 600, and there is mechanical transmission between the winding device and the rope winding drive device 600. The rope is a flexible component. In order to prevent the rope from being rolled into the winding device, the mechanical transmission component between the winding device and the rope winding drive device 600 is covered by the dust cover 102 to prevent the rope from falling into it and getting entangled, thereby reducing the failure rate and improving the reliability of the device.

[0061] In this embodiment, the telescopic clamp 300 includes a first clamp rod 310 and a second clamp rod 320, and the connecting rod device includes a slider 401, a first connecting rod 420 and a second connecting rod;

[0062] The first clamping rod 310 and the second clamping rod 320 are hingedly fixed on the sliding seat 200;

[0063] One end of the first clamping rod 310 and the second clamping rod 320 is a clamping portion 301 that penetrates the working platform 101, and the other end is a handle portion 302, and the handle portion 302 is bent outward;

[0064] The slider 401 is slidably mounted on the sliding seat 200, one end of the first connecting rod 420 and the second connecting rod is hinged to the slider 401, and the other end is respectively hinged to the handles 302 of the first clamping rod 310 and the second clamping rod 320. The first clamping rod 310 and the second clamping rod 320 are cross-hinged and fixed on the sliding seat 200, and the first clamping rod 310 and the second clamping rod 320 are opened, closed and clamped by the connecting rod device.

[0065] In this embodiment, the slider 401 moves upward relative to the sliding seat 200, and the slider 401 drives the first clamping rod 310 and the second clamping rod 320 to open through the first connecting rod 420 and the second connecting rod. The bent handles of the first clamping rod 310 and the second clamping rod 320 have a guiding function. When the slider 401 moves upward, the bent handles guide the first clamping rod 310 and the second clamping rod 320 to open outward.

[0066] When the slider 401 moves downward relative to the sliding seat 200 , the slider 401 pulls the first clamping rod 310 and the second clamping rod 320 to close through the first connecting rod 420 and the second connecting rod.

[0067] In this embodiment, when the slider 401 moves to the lowest end relative to the sliding seat 200, the slider 401 drives the sliding seat 200 to move downward, and the slider 401 maintains the first clamping rod 310 and the second clamping rod 320 in a clamped closed state through the first connecting rod 420 and the second connecting rod.

[0068] In this embodiment, a preload spring is provided between the bottom end of the sliding seat 200 and the base 100. Considering that the lifting cylinder 400 has a two-stage retraction process, the first stage of driving is to drive the slider 401 to move downward relative to the sliding seat 200 so that the telescopic clamp 300 completes the clamping action, and the second stage of driving is to drive the slider 401 to drive the sliding seat 200 to move downward so that the telescopic clamp 300 moves downward. In order to ensure the stability of the sliding seat 200 during the first stage of driving, a certain preload spring is used to apply a certain preload elastic force to ensure that during the first driving process, the sliding seat 200 will not slide down synchronously with the sliding block due to friction, affecting the clamping effect of the telescopic clamp 300.

[0069] In another embodiment, the sliding seat 200 and the sliding column 104 are interference fit, and the friction between the sliding seat 200 and the sliding column 104 is increased to ensure that the sliding seat 200 will not slide down synchronously with the sliding block due to friction during the first drive process, affecting the clamping effect of the telescopic clamp 300.

[0070] In this implementation case, the chain head fixing device 700 is located on the side of the telescopic clip 300;

[0071] The chain head fixing device 700 is provided with a positioning groove 701, and the positioning groove 701 is used to fix the chain head;

[0072] The top of the positioning groove 701 is provided with a through groove 702 for the rope to pass through. The chain head is half-embedded in the positioning groove 701 to achieve fixation, and the rope to be knotted on the chain head passes through the through groove 702 and passes through the chain head fixing device 700, and then the end of the rope is fixed on the telescopic clamp 300. The chain head fixing device 700 has a simple structure and is easy to disassemble.

[0073] In this embodiment, a rope positioning device 800 is also included, which is fixed on the working platform 101 and is located above the telescopic clamp 300. The rope positioning device 800 is used to limit the freedom of the rope. In order to prevent the rope from skipping over the telescopic clamp 300 during the winding process, resulting in a winding failure, the rope positioning device 800 covers the top of the telescopic clamp 300 to prevent the rope from skipping over the telescopic clamp 300, thereby ensuring the winding efficiency.

[0074] In this embodiment, the side height limiting block of the rope positioning device 800 is only at a distance from the work platform 101 for the winding paddle 501 of the rotating sleeve 500 to pass through, so as to prevent the rope from passing over the winding paddle 501 and affecting the efficiency of winding.

[0075] In this embodiment, the rope positioning device 800 includes a pressure rod 801 and an operating handle 802;

[0076] The pressure rod 801 is hinged to the working platform 101, and the operating handle 802 is used to drive the rotation of the pressure rod 801. When the rope is fixed in the process, the pressure rod 801 is first lifted by the operating handle 802 for easy operation. After the expansion clamp 300 is clamped and retracted, the pressure rod 801 is driven to reset by the operating handle 802.

[0077] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
