Description

Technical Field

[0001] This utility model relates to the field of hemp fiber forming technology, specifically to a clamp for hemp fiber forming and tightening with an adjustable function. Background Technology

[0002] As a typical natural plant fiber, hemp fiber has important application value in textiles, composite material reinforcement and other fields. However, its unique physical properties (uneven diameter, rough surface and poor tensile strength) pose a serious challenge to traditional processing equipment.

[0003] Currently, in order to obtain hemp fiber materials that meet the usage requirements, hemp fibers need to be processed and shaped. Hemp fiber shaping involves clamping and fixing multiple hemp fibers with clamps, then rotating and winding them simultaneously to form a high-strength hemp rope. However, the existing method of fixing hemp fibers involves manually rotating a screw to push a metal clamp (such as a vise structure) to directly squeeze the fiber bundle and use friction to achieve fixation. This method is not only cumbersome when fixing multiple hemp fibers, but also makes it difficult to control the clamping force of each fiber evenly, which can easily lead to over-clamping, damage to the fibers, and breakage.

[0004] Therefore, it is of great importance to design a clamp with adjustable function for hemp fiber forming and tightening to solve the above-mentioned defects. Utility Model Content

[0008] The synchronous clamping mechanism includes two sets of connecting sleeves fixedly connected to the outside of the forming shaft. Multiple sets of fixed clamping plates are installed at equal intervals on the outside of the two sets of connecting sleeves.

A threaded sleeve is threaded to the front end of the rotating stud. A movable sleeve is rotatably connected to the outside of the threaded sleeve. A second linkage rod is installed between the multiple sets of fixed clamping plates and the movable sleeve. A clamping groove is opened on the inner side of the clamping sleeve at a position corresponding to the multiple sets of fixed clamping plates.

[0009] As a preferred embodiment of this utility model, the rear end of the clamping sleeve is fixedly connected to the outer side of the forming shaft, and multiple sets of the fixing clamps are distributed at equal intervals between the forming shaft and the clamping sleeve.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-4This utility model provides a technical solution:

[0025] A clamp for forming and tightening hemp fibers with adjustable function includes a support frame 1. An adjustment groove 2 is provided at the rear end of the support frame 1. An adjustment seat 3 is slidably connected inside the adjustment groove 2, and a forming shaft 4 is rotatably connected inside the adjustment groove 2. A clamping sleeve 5 is fixedly installed on the outside of the forming shaft 4. A synchronous clamping mechanism 6 is installed between the forming shaft 4 and the clamping sleeve 5. A tension adjusting frame 7 and a bundled sleeve 8 are fixedly installed on the top of the support frame 1 and in front of the forming shaft 4, respectively.

[0026] First, in this embodiment, the specific structure of the synchronous clamping mechanism 6 is as follows:

[0027] The synchronous clamping mechanism 6 includes two sets of connecting sleeves 601 fixedly connected to the outside of the forming shaft 4. Multiple sets of fixed clamping plates 602 are installed at equal intervals on the outside of the two sets of connecting sleeves 601. A first linkage rod 603 is installed between each set of fixed clamping plates 602 and the two sets of connecting sleeves 601. A rotating stud 604 is rotatably connected inside the forming shaft 4. A threaded sleeve 605 is threaded to the front end of the rotating stud 604. A movable sleeve 606 is rotatably connected to the outside of the threaded sleeve 605. A second linkage rod 607 is installed between each set of fixed clamping plates 602 and the movable sleeve 606. Clamping grooves 608 are provided on the inner side of the clamping sleeve 5 at positions corresponding to the multiple sets of fixed clamping plates 602. All hemp fiber bundles are first inserted into the bundled sleeve 8 to form a single strand, and then passed through the tension adjusting frame 7 before being guided into the clamp. Inside the tight sleeve 5, all the hemp fiber bundles are divided equally according to the number of clamping grooves 608 and then inserted into the interior of the clamping grooves 608 respectively. Then, the rotating stud 604 is rotated, and the moving sleeve 606 is moved backward under the connection of the threaded sleeve 605. Under the transmission of multiple sets of first linkage rods 603 and second linkage rods 607, multiple sets of fixed clamping plates 602 are stably driven to synchronously support the outside, so that the hemp fiber bundles in all the clamping grooves 608 can be clamped and fixed at the same time. This not only improves the convenience of operation by clamping and fixing all the hemp fiber bundles at one time, but also ensures the uniformity of clamping force by clamping and fixing at the same time. This protects the hemp fibers from breakage and allows them to be wound and tightened normally to form a high-strength hemp rope, further ensuring the quality of the hemp fiber after molding.

[0028] Furthermore, the rear end of the clamping sleeve 5 is fixedly connected to the outer side of the forming shaft 4, and multiple sets of fixing plates 602 are evenly distributed between the forming shaft 4 and the clamping sleeve 5. The rear end of the clamping sleeve 5 is fixed to the outer side of the forming shaft 4, so that after the multiple strands of hemp fiber bundles are clamped and fixed, the clamping sleeve 5 can also be rotated by rotating the forming shaft 4, thereby winding and tightening the multiple strands of hemp fiber bundles to form a high-strength hemp rope. At the same time, the evenly distributed fixing plates 602 can better ensure the uniformity of the clamping force.

[0029] Then, the two ends of the first linkage rod 603 are hinged to the connecting sleeve 601 and the fixed clamping plate 602 respectively, and the two ends of the second linkage rod 607 are hinged to the moving sleeve 606 and the fixed clamping plate 602 respectively. The outer side of the front end of the rotating stud 604 is fixedly connected to the operating handle 609. The front end of the moving sleeve 606 is threadedly connected to the locking bolt 610, and the locking bolt 610 abuts against the outer side of the threaded sleeve 605. First, loosen the locking bolt 610 and use the operating handle 609 to rotate the rotating stud 604. Under the connection of the threaded sleeve 605, the moving sleeve 606 is driven to move backward. Under the transmission of multiple sets of first linkage rods 603 and second linkage rods 607, multiple sets of fixed clamping plates 602 are stably driven to synchronously support each other. Thus, the hemp fiber bundles in all clamping slots 608 can be clamped and fixed synchronously. After the hemp fiber bundles are clamped and fixed, the locking bolt 610 is tightened to abut against the threaded sleeve 605 to prevent it from rotating, thereby ensuring the firmness of the hemp fiber bundles after clamping and fixing.

[0030] Furthermore, an adjusting screw 201 is rotatably connected to the right end of the adjusting groove 2. A screw motor 202 is fixedly installed at the top of the support frame 1 at a position corresponding to the adjusting screw 201, and the drive end of the screw motor 202 is fixedly connected to the top end of the adjusting screw 201. The right end of the adjusting seat 3 is connected to the adjusting screw 201 through a screw nut 203. The screw motor 202 can drive the adjusting screw 201 to rotate. Under the connection of the screw nut 203, the adjusting seat 3 is driven to slide up and down inside the adjusting groove 2, which can adjust the tension of the hemp fiber bundle and avoid the loose state when the multi-strand hemp fiber bundle is wrapped and tightened, which affects the molding effect. Stable sliders 301 are fixedly connected to both the left and right ends of the adjusting seat 3. Both sets of stable sliders 301 are slidably connected to the inside of the adjusting groove 2 through a sliding groove 302. When the adjusting seat 3 moves up and down, the stable sliders 301 slide inside the sliding groove 302, thereby improving the movement stability of the adjusting seat 3.

[0031] Secondly, the rear end of the forming shaft 4 is rotatably connected to the inside of the adjusting seat 3 through the bearing 401. The back of the adjusting seat 3 is fixedly installed with a reduction motor 402, and the drive end of the reduction motor 402 is fixedly connected to the rear end of the forming shaft 4. After the multi-strand hemp fiber bundle is clamped and fixed, the forming shaft 4 is driven to rotate by the reduction motor 402, thereby winding and tightening the multi-strand hemp fiber bundle to form a high-strength hemp rope.

[0032] Finally, guide rope wheels 701 are rotatably connected to both the front and rear ends of the left side of the tension adjusting frame 7. A lifting block 702 is slidably connected to the middle of the inside of the tension adjusting frame 7. An adjusting wheel 703 is rotatably connected to the outside of the lifting block 702. An adjusting screw 704 is threadedly connected inside the tension adjusting frame 7. An operating knob 705 is fixedly installed at the top of the adjusting screw 704. The bottom end of the adjusting screw 704 is rotatably connected to the lifting block 702. After all the hemp fiber bundles are inserted into the inside of the bundle sleeve 8, they first wind around the inside of the tension adjusting frame 7 from the front guide rope wheel 701. The fiber bundle then passes under the adjusting wheel 703 and out from above the guide wheel 701 at the rear end. The guide wheel 701 and the inner groove of the adjusting wheel 703 guide and transmit the hemp fiber bundle. Finally, it is inserted into the inner side of the clamping sleeve 5 and clamped and fixed by multiple sets of fixing plates 602. The operating knob 705 can drive the adjusting screw 704 to rotate, thereby driving the lifting block 702 to slide inside the tension adjusting frame 7. This allows the tension of the hemp fiber bundle to be adjusted, preventing the loose state of the multi-strand hemp fiber bundle when it is wrapped and tightened, which would affect the molding effect.

[0033] In this embodiment, the specific implementation scenario is as follows: all hemp fiber bundles are first inserted into the bundle sleeve 8 to form a single strand. They are then wound around the tension adjusting frame 7 from the front guide wheel 701, then around the adjusting wheel 703 from below, and finally out from above the rear guide wheel 701. The guide wheel 701 and the grooves on the inner sides of the adjusting wheel 703 guide and transmit the hemp fiber bundles. Finally, they are inserted into the clamping sleeve 5 and clamped by multiple sets of fixing plates 602. The operating knob 705 drives the adjusting screw 704 to rotate, thereby causing the lifting block 702 to slide inside the tension adjusting frame 7, thus adjusting the tension of the hemp fiber bundles. Based on the number of clamping slots 608, all hemp fiber bundles are then divided equally and inserted into the clamping slots 608 respectively. Then, the rotating stud 604 is rotated, causing the moving sleeve 606 to move backward under the connection of the threaded sleeve 605. Multiple sets of first linkage rods 603 and the first... Driven by the two linkage rods 607, multiple sets of fixed clamping plates 602 are stably driven to synchronously support the outside, thereby simultaneously clamping and fixing the hemp fiber bundles in all clamping slots 608. The lead screw motor 202 drives the adjusting lead screw 201 to rotate, and the adjusting seat 3 slides up and down inside the adjusting slot 2 under the connection of the lead screw nut 203. In conjunction with the tension adjusting frame 7, the tension of the hemp fiber bundles is further adjusted. The adjusting seat 3 is used to achieve overall coarse tension adjustment, and the manually controlled adjusting wheel 703 completes local fine adjustment, avoiding the loose state when the multi-strand hemp fiber bundles are wound and tightened, which affects the molding effect. The reduction motor 402 drives the molding shaft 4 to rotate, thereby winding and tightening the multi-strand hemp fiber bundles to form a high-strength hemp rope. The whole operation process is simple and convenient. This utility model overcomes the pain points of uneven clamping force, coarse tension control and cumbersome operation in hemp fiber molding, and significantly improves the quality and production efficiency of hemp fiber molding.
