[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] Reference Figure 1 The sling machine shown includes a base 100, on which a guide rail 101 is arranged. The strip material 800 can be transported forward along the guide rail 101. A pulling mechanism 200 is arranged above the guide rail 101. The sling machine also includes a clamping mechanism 300, a cutting mechanism 600, a guide assembly and a hook mechanism 400 which are arranged in sequence along the conveying direction of the strip material 800.

[0037] Reference Figures 2 to 4 The pulling back mechanism 200 shown includes a pressing assembly 230, which is connected to a horizontal driving mechanism 210 and a vertical driving mechanism 220. The strip material 800 is placed on the guide rail 101, and the vertical driving mechanism 220 drives the pressing assembly 230 to move downward to press the strip material 800. The horizontal driving mechanism 210 drives the pressing assembly 230 to drive the strip material 800 to be transported forward along the guide rail 101 for a certain distance, so that the clamping mechanism 300 can accurately clamp the end of the strip material 800. After the strip material 800 is cut, the horizontal driving mechanism 210 can also drive the pressing assembly 230 to drive the strip material 800 to be transported backward along the guide rail 101 for a certain distance, that is, to pull the strip material 800 back for a certain distance. Ensure that the next operation process can run accurately; it should be noted that after the clamping mechanism 300 accurately clamps the end of the strip material 800, the pressure-feeding component 230 moves upward for a distance, that is, the pressing force of the pressure-feeding component 230 relative to the strip material 800 is cancelled, avoiding interference with the hook mechanism 400 to hook out the strip material 800.

[0038] In some embodiments, the pressure-feeding assembly 230 includes a crimping portion 231 and a guide portion 232 which are sequentially arranged along the conveying direction of the strip material 800. An anti-slip structure 233 is arranged on the side of the crimping portion 231 relatively close to the strip material 800. Specifically, the guide portion 232 is arranged close to the front end of the guide assembly, and its purpose is to prevent the front end of the strip material 800 from tilting up. The anti-slip structure 233 is arranged on the lower end surface of the crimping portion 231 to ensure the static friction between the pressure-feeding assembly 230 and the strip material 800. Specifically, the anti-slip structure 233 can be arranged as a plurality of anti-slip teeth or a mesh shape, which can ensure the relative static friction between the pressure-feeding assembly 230 and the strip material 800.

[0039] In some embodiments, the guide portion 232 and the crimping portion 231 are integrally formed, and the pressing assembly 230 can be made of metal materials such as iron alloy or aluminum alloy to reduce costs. In other embodiments, the guide portion 232 is rod-shaped and its cross-sectional area is smaller than the cross-sectional area of ​​the crimping portion 231. The guide portion 232 of the rod-shaped structure not only plays the role of crimping the strip material 800, but also can achieve avoidance to prevent interference between the pulling back mechanism 200 and the clamping mechanism 300.

[0040] It should be noted that the horizontal driving mechanism 210 and the vertical driving mechanism 220 described in the above-mentioned embodiment can both be conventional telescopic cylinders, the output end of the horizontal driving mechanism 210 is connected to the moving block 211, the vertical driving mechanism 220 is arranged on the moving block 211, and the pressure delivery assembly 230 is arranged on the output end of the vertical driving mechanism 220.

[0041] Reference Figures 2 to 4 The clamping mechanism 300 shown in the figure includes a fixed claw 310 and a moving claw 320. The fixed claw 310 has two groups and is respectively arranged above and below the moving claw 320. The moving claw 320 is connected to a first driving mechanism, and the first driving mechanism is used to drive the moving claw 320 to move upward to clamp the end of the strip material 800 and move downward to clamp the extended section of the strip material 800. Specifically, the pull-back mechanism 200 sends the end of the strip material 800 to the top of the moving claw 320, and the first driving mechanism drives the moving claw 320 to move upward and cooperates with the fixed claw 310 located above the moving claw 320 to clamp the end of the strip material 800. At this time, the end of the strip material 800 is located above its conveying direction, that is, the strip material 800 is inclined, which is convenient for the hook assembly to hook the side close to the pull-back mechanism 200, and wait for the hook mechanism to After 400 pulls out the strip material 800 along its hooking point and bends it to a certain length, the guide assembly moves downward to engage and position the upper and lower sections of the bent strip material 800 to overlap. At this time, the first driving mechanism drives the moving claw 320 to move downward to release the end of the strip material 800, and the moving claw 320 continues to move downward and cooperates with the fixed claw 310 located below the moving claw 320 to clamp the extended section of the strip material 800. At this time, the hook mechanism 400 cannot continue to pull out the extended section of the strip material 800. Therefore, when the hook mechanism 400 continues to pull the strip material 800, the end of the strip material 800 can be pulled out to achieve a slight adjustment of the end along the guide assembly to ensure that the upper and lower ends of the strip material 800 overlap; then the cutting mechanism 600 moves downward to cut off the strip material 800, thereby completing the bending and cutting functions.

[0042] It should be noted that the first driving mechanism of all the above embodiments can be a telescopic cylinder commonly used in the market.

[0043] In some embodiments, Figure 1 and Figure 5 As shown, the guide assembly is arranged between the clamping mechanism 300 and the hook mechanism 400, which is connected to a driving source 510. A guide groove is arranged on the guide assembly. The driving source 510 can drive the guide assembly to move toward the strip material 800 to clamp and position the strip material 800. Specifically, the driving source 510 can be a telescopic cylinder commonly used on the market, and the guide groove is opened on the side of the guide assembly close to the strip material 800.

[0044] In some other embodiments, the guide groove is in a trumpet shape, that is, the cross-sectional dimension of the guide groove at one end closer to the strip material 800 is larger than the cross-sectional dimension of the end relatively far away from the strip material 800. The purpose is to ensure that the upper and lower sections of the strip material 800 can be snapped into the guide groove and the size of the guide groove gradually becomes smaller to achieve the positioning function.

[0045] In some other embodiments, the guide assembly includes a horizontal rod 501 and two clamping plates 502 arranged on the horizontal rod 501. The gap between the two clamping plates 502 forms a guide groove. Specifically, a threaded hole is provided on the horizontal rod 501, and a waist-shaped hole is provided on the clamping plate 502. The locking screw passes through the waist-shaped hole and cooperates with the threaded hole to fix the clamping plate 502 on the horizontal rod 501. In other words, the gap between the two clamping plates 502 is adjustable.

[0046] In some embodiments, reference Figure 6 The hook mechanism 400 is connected to the second driving mechanism 410, and the hook mechanism 400 includes a claw assembly 420 and a rotating driving mechanism 430. The rotating driving mechanism 430 is arranged at the output end of the second driving mechanism 410, and the claw assembly 420 is arranged at the output end of the rotating driving mechanism 430. The second driving mechanism 410 can be a linear slide commonly used on the market. This embodiment adopts a structure in which a driving motor drives the linear slide to slide along a slide rail through a transmission belt, which can drive the rotating driving mechanism 430 to move toward a direction close to the clamping assembly. The rotating driving mechanism 430 can be a rotating cylinder commonly used on the market, which can drive the claw assembly 420 to rotate a certain angle to hook the side of the strip material 800 that is relatively close to the pull-back mechanism 200, and the linear slide can be reset to bend and pull out the strip material 800 from the hooking point.

[0047] In some embodiments, the claw assembly 420 includes an integrally formed connecting portion and a hook portion, one end of the connecting portion is connected to the output end of the rotating drive mechanism 430, and the front end of the hook portion is in an inclined arc shape. Specifically, the rotating drive mechanism 430 includes a rotating shaft, and one end of the connecting portion is radially fixedly installed on the rotating shaft, so that the connecting portion rotates in the horizontal direction along the connection point with the rotating shaft by a certain angle as the rotating shaft rotates, thereby enabling the hook portion to hook the strip material 800; and in the present embodiment, the purpose of the inclined arc shape of the front end of the hook portion is to ensure that the hook portion can accurately hook the side of the strip material 800 that is relatively away from the hook mechanism 400.

[0048] In some embodiments, the hook mechanism 400 also includes a clamping claw assembly 440 disposed at the front end of the claw assembly 420, and the clamping claw assembly 440 is connected to a linear drive mechanism, which can be a telescopic cylinder commonly used on the market, which can drive the clamping claw assembly 440 to move closer to or away from the strip material 800 in the horizontal direction relative to the claw assembly 420. Specifically, the linear drive mechanism is arranged at the output end of the second drive mechanism 410; the clamping claw assembly 440 includes two claw members that can move relatively, and the claw assembly 420 can pass between the two claw members, that is, the rotation drive mechanism 430 drives the claw assembly 420 to rotate a After the angle is determined and the strip material 800 is hooked, the linear drive mechanism can drive the clamping jaw assembly 440 to move toward the strip material 800. At this time, the hooking jaw assembly 420 connects the area of ​​the strip material 800 between the two claw members, and then the two claw members are relatively close to clamp the part of the strip material 800 that is relatively close to the bending point, ensuring that the hook mechanism 400 stably clamps or hooks the bending point of the strip material 800; in this embodiment, the linear slide can first move a certain distance in the reset direction to avoid interference between the clamping jaw assembly 440 and the cutting mechanism 600 or the clamping mechanism 300 when it moves toward the strip material 800.

[0049] In some embodiments, reference Figure 3 and Figure 4 The cutting mechanism 600 includes a cutting drive 620 and a cutter 610 arranged at the output end of the cutting drive 620. The cutting groove can adopt a common model in the industry, and the cutting drive 620 can be a telescopic cylinder or a linear slide commonly used on the market. The cutter 610 is at the lower end of the linear slide. The cutting drive 620 is arranged in the radial direction along the conveying direction of the strip material 800, which can drive the cutter 610 to move toward the strip material 800 and cut the strip material 800.

[0050] In some embodiments, Figure 5As shown, the sling machine also includes a transfer mechanism 700, the function of which is to transfer the bent and cut sling out of the sling machine to facilitate the next process flow. Specifically, the transfer mechanism 700 is connected to a third drive mechanism 710, which can be a telescopic cylinder commonly used on the market. The transfer mechanism 700 includes a support assembly 720 arranged on the lower side of the strip material 800 and a clamping assembly 730 arranged on the upper side of the strip material 800. The clamping assembly 730 is connected to a fourth drive mechanism 740, which can be a telescopic cylinder commonly used on the market. When in use, the fourth drive mechanism 740 drives the clamping assembly 730 to move downward to clamp the strip material 800, and then the cutting mechanism 600 is started and cuts the strip material 800 to form a sling in a bent state, and then the hook mechanism 400 is reset, and then the transfer mechanism 700 can be to clamp one end of the sling and transfer the sling out of the sling machine.

[0051] In some other embodiments, the support assembly 720 and the clamping assembly 730 are provided in two corresponding groups, and the two groups are provided with a gap, and the two groups of support assemblies 720 are provided horizontally. That is, after the sling is cut, two points on the sling can be clamped by correspondingly cooperating with the two groups of support assemblies 720 and the two groups of clamping assemblies 730, so that a section of the sling is horizontal, which is convenient for the next process flow.

[0052] In some embodiments, the clamping assembly 730 includes a vertically arranged elastic member, which can elastically push the upper end surface of the supporting assembly 720 to clamp the strip material 800. Specifically, the elastic member can be a compression spring commonly used in the market.

[0053] A sling cutting method comprises the following steps:

[0054] The pressing assembly 230 presses the strip material 800 and drives the strip material 800 to be transported forward along the guide rail 101 to the clamping mechanism 300; specifically, the pressing assembly 230 moves downward to press the strip material 800 on the guide rail 101 and drives the strip material 800 to be transported forward along the guide rail 101, and at this time, the end of the strip material 800 extends into the clamping mechanism 300;

[0055] The moving claw moves upward and cooperates with the fixed claw 310 above it to clamp the end of the strip material 800. At this time, the end of the strip material 800 has enough length to extend into the clamping mechanism 300 to ensure that it has enough margin to be clamped on the upper end surface of the moving claw. At this time, the strip material 800 is inclined along its axial direction, that is, the end of the strip material 800 is higher than its extension section.

[0056] The hook mechanism 400 moves toward the direction close to the clamping mechanism 300, and the rotating driving mechanism 430 drives the hook claw assembly 420 to hook the side of the bagged material relatively far away from the hook mechanism 400, and the hook mechanism 400 is reset to hook and take out the strip material 800; specifically, during this process, the moving claw 320 cooperates with the fixed claw 310 above it to clamp the end of the strip material 800, and the pressure-feeding assembly 230 does not restrict the extended section of the strip material 800 from being conveyed along the guide rail 101, so that the hook mechanism 400 can smoothly pull out the strip material 800;

[0057] The guide assembly moves downward to engage and position the strip material 800; specifically, after the hook mechanism 400 pulls the strip material 800 out to pass over the guide assembly, the guide assembly moves downward to engage the strip material 800, and a guide groove is provided on the guide assembly, and the upper and lower sections of the strip material 800 are both engaged in the guide groove to ensure that the upper and lower sections of the strip material 800 overlap;

[0058] The moving claw 320 moves downward and cooperates with the fixed claw 310 below it to clamp the extended section of the strip material 800. At this time, the end of the strip material 800 is clamped on the upper side of the extended section by the guide assembly, the hook claw assembly 420 hooks the bending point of the strip material 800, and the clamping mechanism 300 clamps the extended section of the strip material 800.

[0059] The hook mechanism 400 moves in a direction away from the clamping mechanism 300 to adjust the position of the end of the strip material 800 relative to the cutting mechanism 600, so that the cutting mechanism 600 can accurately cut a sling of a suitable length;

[0060] The cutter 610 moves toward a direction approaching the strip material 800 to cut the strip material 800 , so that the strip material 800 forms a sling bent along the hooking point of the hook mechanism 400 .

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
