AI Technical Summary
After the existing plastic braided rope feeding device stops operation, the braided rope is loose due to inertia, and lacks pretension during startup, resulting in the problem of "bulging" in the woven bags, affecting the production quality.
A tensioning feeding device including a frame, a support shaft, a positioning rod, a slide seat, a limit shaft and a tensioning mechanism is designed. The braided rope is pressed and limited by a tensioning rod and limiting the limit. Components such as bit springs, chunks and compression wheels ensure that the braided rope is not loose when shut down and do not eat too much rope when starting.
It effectively avoids the inertial conveying of braided ropes during shutdown and excessive consumption during startup, and improves the production quality of braided bags.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic braided rope feeding, in particular to a tensioning feeding device for plastic braided ropes. Background Art
[0002] Woven bags are packaging bags woven by bag looms using plastic braided ropes. During the production process, a special feeding device is required to feed the plastic braided ropes. Existing plastic braided ropes are usually fed in the form of coils, which are placed on reels. The bag loom pulls the coils to rotate. When the bag loom stops, the coils will still rotate a certain angle under the action of inertia, causing the braided ropes to continue to be transported forward, which makes the braided ropes loose. When the bag loom is started again, due to the lack of pre-tightening force on the braided ropes, the bag loom will eat too much braided rope at the moment of starting, causing the "bulge" problem in the local position of the woven bag, which in turn affects the production quality of the woven bag. Utility Model Content
[0003] To solve the above problems, the utility model provides a tensioning feeding device for plastic braided rope, comprising a frame, a supporting shaft, a positioning rod, a slide seat, a limiting shaft and a tensioning mechanism, wherein the supporting shaft is longitudinally and rotatably arranged on the frame, the positioning rod is longitudinally arranged on the frame and is located on one side of the supporting shaft, the slide seat is slidably sleeved on the positioning rod and is connected to the limiting shaft through a connecting rod, the limiting shaft is coaxially arranged with the supporting shaft, and the tensioning mechanism is arranged on the other side of the positioning rod and is located below the slide seat.
[0004] Furthermore, the tensioning mechanism includes a telescopic rod, a limit spring, a pressure block and a pressure wheel. The telescopic rod is longitudinally arranged on one side of the positioning rod and the upper end is connected to the positioning rod through a fixed block. The pressure block is arranged at the lower end of the telescopic rod. The limit spring is sleeved on the outside of the telescopic rod and the two ends are respectively abutted against the fixed block and the pressure block. The pressure wheel is rotatably arranged in the pressure block, and a limit block is also provided under the pressure block.
[0005] Furthermore, a mounting groove is provided inside the pressing block, and the pressing wheel is arranged in the mounting groove and has two ends rotatably connected to the pressing block.
[0006] Furthermore, the circumferential surface of the pressure wheel is provided with a groove matching the shape of the braided rope.
[0007] Furthermore, a plurality of self-locking universal wheels are provided at the bottom of the frame.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] The tensioning feeding device of the utility model compresses and limits the braided rope through the tensioning mechanism. When the bag loom stops, the braided rope will not continue to be transported forward due to inertia; when the bag loom starts again, the braided rope will not be eaten too much, thereby avoiding the problem of "bulging" of the braided bag and improving the production quality of the braided bag.

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] like Figure 1 As shown, the tension feeding device of the plastic braided rope in this embodiment includes a frame 1, a support shaft 2, a positioning rod 3, a slide 4, a limit shaft 5 and a tensioning mechanism 6. The support shaft 2 is rotatably arranged on the frame 1 along the longitudinal direction, the positioning rod 3 is arranged on the frame 1 along the longitudinal direction and is located on one side of the support shaft 2, the slide 4 is slidably sleeved on the positioning rod 3 and connected to the limit shaft 5 through a connecting rod 7, and the limit shaft 4 is coaxially arranged with the support shaft 2. The coil is sleeved on the support shaft 2 along the longitudinal direction, and the limit shaft 5 is pressed on the top of the coil by its own gravity, so as to position the coil.
[0017] A plurality of self-locking universal wheels 8 are provided at the bottom of the frame 1 to facilitate the movement of the feeding device.
[0018] The tensioning mechanism 6 is arranged on the other side of the positioning rod 3 and is located below the slide 4. The tensioning mechanism 6 includes a telescopic rod 61, a limit spring 62, a pressure block 63 and a pressure wheel 64. The telescopic rod 61 is longitudinally arranged on one side of the positioning rod 3 and the upper end is connected to the positioning rod 3 through a fixed block 9. The pressure block 63 is arranged at the lower end of the telescopic rod 61. The limit spring 62 is sleeved on the outside of the telescopic rod 61 and the two ends are respectively abutted against the fixed block 9 and the pressure block 63. The pressure wheel 64 is rotatably arranged in the pressure block 63, and a limit block 10 is also provided below the pressure block 63.
[0019] Combination Figure 2 and Figure 3 As shown, a mounting groove 65 is provided inside the pressing block 63, a pressing wheel 64 is arranged in the mounting groove 65 and is rotatably connected to the pressing block 63 at both ends, and a groove 66 matching the shape of the braided rope is provided on the circumferential surface of the pressing wheel 64.

The braided rope is pressed on the limit block 10 by the limit spring 62 and the clamping wheel 64 to limit the position of the braided rope. When the bag loom stops, the braided rope will not continue to be conveyed forward due to inertia; when the bag loom starts again, the braided rope will not be taken in too much due to the problem of looseness, thereby avoiding the problem of "bulging" of the woven bag and improving the production quality of the woven bag.
