Description

Technical Field

[0001] This utility model relates to the field of webbing processing equipment technology, and in particular to a positioning structure for the production of ultra-wide webbing. Background Technology

[0002] During the processing and production of webbing, the length can be customized according to customer needs, and different widths need to be processed according to the usage scenario and load-bearing requirements.

[0003] A polyester webbing positioning device is disclosed in Chinese utility model patent with announcement number CN222700533U. The device includes a base plate, a limiting groove, a limiting rod, and a positioning structure. A housing is fixedly installed on the top side of the base plate, and an electric telescopic rod is fixedly installed on the inner top surface of the housing. A shearing structure is fixedly installed at the lower end of the electric telescopic rod, and the positioning structure is snapped onto the rod body of the limiting rod.

[0004] In the process of cutting the polyester webbing, the webbing needs to be placed in the limiting groove. However, the width of the limiting groove cannot be changed, so it cannot adapt to the limiting of webbing of various widths, thus reducing the applicability of the device. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a positioning structure for the production of ultra-wide webbing.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a positioning structure for producing ultra-wide webbing, including a cutting platform and a cutting mechanism disposed on the cutting platform. Two fixing plates are fixed on the top of the cutting platform, and a U-shaped mounting frame is fixed on the top of the two fixing plates. An annular plate is disposed on the mounting frame, and two limiting plates are slidably disposed between the two fixing plates. A distance adjustment mechanism for driving the two limiting plates to move closer or further apart is disposed on the mounting frame.

[0007] By adopting the above technical solution, the worker first places the webbing to be cut between two limiting plates, and then cuts the webbing through the cutting mechanism. In addition, by adjusting the distance between the two limiting plates through the distance adjustment mechanism, the device can accommodate the limiting of webbing of various widths, thus expanding its applicability.

[0008] Furthermore, the distance adjustment mechanism includes an adjustment component, which includes a bidirectional threaded rod rotatably mounted in the annular plate, a guide rod fixed in the annular plate, a rotating wheel fixedly sleeved on the bidirectional threaded rod, and a connecting plate slidably disposed in the annular plate. The connecting plate is fixed to a limiting plate, and the guide rod passes through the connecting plate and is slidably engaged. The number of connecting plates is equal to the number of limiting plates, and their positions correspond one-to-one. Each bidirectional threaded rod is threadedly connected to two connecting plates. The bidirectional threaded rod is provided with two threaded grooves with equal pitch and equal direction of rotation. The two connecting plates are respectively disposed on the two threaded grooves. The distance adjustment mechanism also includes a lifting component for adjusting the height of the annular plate.

[0009] By adopting the above technical solution, the rotating wheel drives the bidirectional threaded rod to rotate. Since the bidirectional threaded rod is threadedly connected to two connecting plates, the bidirectional threaded rod is provided with two threaded grooves with equal pitch and equal direction of rotation. The two connecting plates are respectively set on the two threaded grooves and are slidably set in the annular plate. This allows the two connecting plates and the limiting plates fixed to the two connecting plates to move closer or further away from each other, so as to achieve the limiting purpose of webbing of various widths.

[0010] Furthermore, the cutting platform is provided with a conveying mechanism, which includes a main synchronous pulley rotatably installed in the cutting platform, a driven synchronous pulley rotatably installed in the cutting platform, a synchronous belt for connecting the main synchronous pulley and the driven synchronous pulley, and a conveying motor fixed on the cutting platform and driving the main synchronous pulley to rotate. The synchronous belt meshes with both the main synchronous pulley and the driven synchronous pulley, and the bottom of the limiting plate is in contact with the top of the upper side of the synchronous belt.

[0011] By adopting the above technical solution, after the conveyor motor works, it drives the main synchronous pulley to rotate, thereby causing the synchronous belt meshing with the main synchronous pulley and the slave synchronous pulley meshing with the synchronous belt to rotate. The webbing to be cut is placed on the top of the upper side of the synchronous belt, and the webbing can be automatically moved to the position of the cutting mechanism for cutting, which facilitates the use of the device.

[0012] Furthermore, a sliding through hole is provided through the fixed plate, and a limiting mechanism is provided on the fixed plate. The limiting mechanism includes a slider that is slidably disposed in the sliding through hole. The number of sliders, the number of fixed plates, and the number of sliding through holes are all equal and their positions correspond one-to-one. The limiting mechanism also includes a limiting roller rotatably mounted between two sliders, a limiting frame fixed on one of the sliders, and a limiting motor fixed on the limiting frame and driving the limiting roller to rotate. The output speed of the limiting motor is equal to the output speed of the synchronous belt. The annular plate is slidably disposed on the mounting frame. The limiting roller passes through the two limiting plates and cooperates with them. The lifting assembly includes a second electro-hydraulic push rod fixed on the mounting frame and a connecting frame fixed to the push rod end of the second electro-hydraulic push rod. The connecting frame is fixed to the mounting frame.

[0013] By adopting the above technical solution, the webbing passes between the limiting roller and the synchronous belt. The conveying motor and the limiting motor are driven simultaneously. The output end of the limiting motor drives the limiting roller to rotate, thereby causing the synchronous belt and the limiting roller to rotate synchronously in opposite directions and convey the webbing. The synchronous belt improves the stability of the webbing during conveying. In addition, after the second electro-hydraulic push rod is activated, its push rod end retracts, causing the connecting frame connected to the second electro-hydraulic push rod, the annular plate connected to the connecting frame, the limiting plate connected to the annular plate, the limiting roller connected to the limiting plate, and the slider connected to the limiting roller to all rise. This changes the distance between the limiting roller and the synchronous belt, facilitating the webbing to pass between the limiting roller and the synchronous belt.

[0014] Furthermore, the cutting mechanism includes a cutting assembly, which includes a fixed frame fixed to the cutting platform, a first electro-hydraulic push rod fixed to the fixed frame, a lifting plate fixed to the end of the push rod of the first electro-hydraulic push rod, a cutting blade fixed to the bottom of the lifting plate, and a cutting plate fixed inside the cutting platform. A cutting groove is provided on the top of the cutting plate at a position corresponding to the cutting blade. The cutting mechanism also includes a positioning assembly for positioning the webbing during the cutting of the sling.

[0015] By adopting the above technical solution, after the first electro-hydraulic push rod is working, its push rod end extends, thereby causing the lifting plate at the push rod end of the first electro-hydraulic push rod and the cutting blade fixed to the lifting plate to both descend until the lower end of the cutting blade approaches the bottom wall of the cutting groove. During the descent of the cutting blade, the webbing located on the top of the cutting plate is cut to ensure the normal processing operation of the device.

[0016] Furthermore, the positioning component includes a slide rod that passes through and slides on the lifting plate, a pressure block fixed to the lower end of the slide rod, a limiting block fixed to the upper end of the slide rod, and a spring fixed between the limiting block and the lifting plate. The positioning component is provided in two sets and is symmetrically arranged about the cutting groove.

[0017] By adopting the above technical solution, during the descent of the lifting plate, the sliding rod connected to the lifting plate, the pressure block connected to the sliding rod, the limiting block connected to the pressure block, and the spring connected to the limiting block all descend. The pressure block first contacts the cutting blade and the top of the webbing. As the lifting plate descends, the spring is stressed and stretched. The elastic force generated by the cutting blade acts on the surface of the webbing through the pressure block, thereby ensuring the stability of the webbing when cutting it.

[0018] Furthermore, the bottom of the pressure block has a groove with a wave-shaped structure.

[0019] By adopting the above technical solution, the groove design increases the friction when the pressure block contacts the webbing.

[0020] In summary, the present invention has the following beneficial effects: In this application, by setting a limiting plate and a distance adjustment mechanism, the distance between the two limiting plates can be adjusted, which can adapt to the limiting of webbing of various widths and expand the applicability of the device.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4 As shown in the embodiment of this application, a positioning structure for producing ultra-wide webbing is disclosed, including a cutting platform 1, a distance adjustment mechanism 7, a conveying mechanism 8, a limiting mechanism 9, and a cutting mechanism 6. Two fixing plates 2 are fixed to the top of the cutting platform 1. A sliding through hole 10 is provided through the fixing plate 2. A U-shaped mounting frame 3 is fixed to the top of both fixing plates 2, and an annular plate 4 is provided on the mounting frame 3. Two limiting plates 5 are slidably disposed between the two fixing plates 2. First, the operator places the webbing to be cut between the two limiting plates 5, and then cuts the webbing using the cutting mechanism 6. Furthermore, the distance between the two limiting plates 5 can be adjusted by the distance adjustment mechanism 7 to accommodate webbing of various widths, expanding the applicability of the device.

[0028] A distance adjustment mechanism 7 is mounted on the mounting frame 3. The distance adjustment mechanism 7 is used to drive the two limiting plates 5 closer together or further apart. The distance adjustment mechanism 7 includes an adjustment component 71 and a lifting component 72. The adjustment component 71 includes a bidirectional threaded rod 711, a guide rod 712, a rotating wheel 713, and a connecting plate 714. The bidirectional threaded rod 711 is rotatably mounted inside the annular plate 4, and the guide rod 712 is fixed inside the annular plate 4. The rotating wheel 713 is fixedly sleeved on the bidirectional threaded rod 711, and the connecting plate 714 is slidably mounted inside the annular plate 4. The connecting plate 714 is fixed to the limiting plate 5, and the guide rod 712 passes through the connecting plate 714 and slides in engagement. The number of connecting plates 714 is equal to the number of limiting plates 5, and their positions correspond one-to-one. The bidirectional threaded rods 711 are threadedly connected to both connecting plates 714. The bidirectional threaded rods 711 are provided with two threaded grooves of equal pitch and direction of rotation, and the two connecting plates 714 are respectively mounted on the two threaded grooves. The rotating wheel 713 drives the bidirectional threaded rod 711 to rotate. Since the bidirectional threaded rod 711 is threadedly connected to the two connecting plates 714, the bidirectional threaded rod 711 is provided with two threaded grooves with equal pitch and equal direction of rotation. The two connecting plates 714 are respectively set on the two threaded grooves. The connecting plates 714 are slidably set in the annular plate 4, so that the two connecting plates 714 and the limiting plates 5 fixed to the two connecting plates 714 move closer or further away from each other, so as to achieve the purpose of limiting the width of the webbing.

[0029] The conveying mechanism 8 is mounted on the cutting platform 1 and includes a main synchronous pulley 81, a driven synchronous pulley 82, a synchronous belt 83, and a conveying motor 84. The main synchronous pulley 81 and the driven synchronous pulley 82 are rotatably mounted inside the cutting platform 1. The synchronous belt 83 connects the main synchronous pulley 81 and the driven synchronous pulley 82, and the synchronous belt 83 meshes with both the main synchronous pulley 81 and the driven synchronous pulley 82. The bottom of the limiting plate 5 is abutted against the top of the upper side of the synchronous belt 83. The conveying motor 84 is fixed to the cutting platform 1 and drives the main synchronous pulley 81 to rotate. After the conveying motor 84 operates, it drives the main synchronous pulley 81 to rotate, thereby causing the synchronous belt 83 meshing with the main synchronous pulley 81 and the driven synchronous pulley 82 meshing with the synchronous belt 83 to rotate. By placing the webbing to be cut on the top of the upper side of the synchronous belt 83, the webbing can be automatically moved to the position of the cutting mechanism 6 for cutting, facilitating the use of the device.

[0030] A limiting mechanism 9 is mounted on a fixed plate 2 and includes a slider 91, a limiting roller 92, a limiting frame 93, and a limiting motor 94. The slider 91 is slidably disposed within a sliding through hole 10. The number of sliders 91, the number of fixed plates 2, and the number of sliding through holes 10 are all equal and their positions correspond one-to-one. The limiting roller 92 is rotatably mounted between two sliders 91, passing through and engaging with two limiting plates 5. The limiting frame 93 is fixed to one of the sliders 91. The limiting motor 94 is fixed to the limiting frame 93 and drives the limiting roller 92 to rotate. The output speed of the limiting motor 94 is equal to the output speed of the synchronous belt 83. The rotation direction of the output of the limiting motor 94 is opposite to the rotation direction of the output of the synchronous belt 83. The annular plate 4 is slidably disposed on a mounting frame 3. The lifting assembly 72 is used to adjust the height of the annular plate 4. The lifting assembly 72 includes a second electro-hydraulic push rod 721 and a connecting frame 722. The second electro-hydraulic push rod 721 is fixed to the mounting frame 3. The connecting frame 722 is fixed to the push rod end of the second electro-hydraulic push rod 721 and is fixed to the mounting frame 3. The webbing is passed between the limiting roller 92 and the synchronous belt 83. The conveying motor 84 and the limiting motor 94 are driven simultaneously. The output end of the limiting motor 94 drives the limiting roller 92 to rotate, thereby causing the synchronous belt 83 and the limiting roller 92 to rotate synchronously in opposite directions, thus conveying the webbing. The synchronous belt 83 improves the stability of the webbing during conveying. Furthermore, after the second electro-hydraulic push rod 721 is activated, its push rod end retracts, causing the connecting frame 722 connected to the second electro-hydraulic push rod 721, the annular plate 4 connected to the connecting frame 722, the limiting plate 5 connected to the annular plate 4, the limiting roller 92 connected to the limiting plate 5, and the slider 91 connected to the limiting roller 92 to all rise, thereby changing the distance between the limiting roller 92 and the synchronous belt 83, making it easier for the webbing to pass between the limiting roller 92 and the synchronous belt 83.

[0031] The cutting mechanism 6 is mounted on the cutting platform 1 and includes a cutting assembly 61 and a positioning assembly 62. The cutting assembly 61 includes a fixing frame 611, a first electro-hydraulic push rod 612, a lifting plate 613, a cutting blade 614, and a cutting plate 615. The fixing frame 611 is fixed to the cutting platform 1. The first electro-hydraulic push rod 612 is fixed to the fixing frame 611, and the lifting plate 613 is fixed to the push rod end of the first electro-hydraulic push rod 612. The cutting blade 614 is fixed to the bottom of the lifting plate 613, and the cutting plate 615 is fixed inside the cutting platform 1. A cutting groove is formed on the top of the cutting plate 615 at a position corresponding to the cutting blade 614. After the first electro-hydraulic push rod 612 is activated, its push rod end extends, thereby causing the lifting plate 613 and the cutting blade 614 fixed to the lifting plate 613 to descend until the lower end of the cutting blade 614 approaches the bottom wall of the cutting groove. During the descent of the cutting blade 614, the webbing located on the top of the cutting plate 615 is cut to ensure the normal processing operation of the device.

[0032] The positioning assembly 62 is used to position the webbing during webbing cutting. Two sets of positioning assemblies 62 are provided and symmetrically arranged about the cutting groove. The positioning assembly 62 includes a slide rod 621, a pressure block 622, a limiting block 623, and a spring 624. The slide rod 621 passes through and slides on the lifting plate 613. The pressure block 622 is fixed to the lower end of the slide rod 621, the limiting block 623 is fixed to the upper end of the slide rod 621, and the spring 624 is fixed between the limiting block 623 and the lifting plate 613. During the descent of the lifting plate 613, the slide rod 621 connected to the lifting plate 613, the pressure block 622 connected to the slide rod 621, the limiting block 623 connected to the pressure block 622, and the spring 624 connected to the limiting block 623 all descend. The pressure block 622 first contacts the top of the webbing with the cutting blade 614. As the lifting plate 613 descends, the spring 624 is stressed and stretched. The elastic force generated by the cutting blade 614 acts on the surface of the webbing through the pressure block 622, thereby ensuring the stability of the webbing during cutting.

[0033] The bottom of the pressure block 622 has a groove with a wave-shaped structure. The groove increases the friction between the pressure block 622 and the webbing.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
