Description

An automatic tensioning and shearing device for textile manufacturing Technical Field

[0001] This utility model relates to the field of textile manufacturing technology, and in particular to an automatic tensioning and shearing device for textile manufacturing. Background Technology

[0002] For example, Chinese Patent No. CN219824698U discloses an automatic tensioning and cutting device for textile manufacturing. The device uses an electric push rod to easily move the blade to cut the textile, and two rotating wheels to easily tension the textile. The control mechanism allows the movement of the locking block to fix or unlock the control box, so as to adjust the position of the rotating wheel on the right side and thus adjust the tension of the textile.

[0003] However, the shearing device in the above application requires manual adjustment of the tension of the textile. During the unloading process, wrinkles may occur due to the initial winding, which may cause slight changes in the tension of the textile. This may result in the tension that was manually adjusted in advance not being perfectly matched. Therefore, it is necessary to automatically adapt to the tension changes of the textile during unloading. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic tensioning and shearing device for textile manufacturing. It solves the technical problem that the fixed tension adjustment mechanism in the prior art cannot adapt to the slight tension changes that occur during the unloading process of textiles, and achieves the purpose of automatically adjusting the tension of textiles during the unloading process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic tensioning and shearing device for textile manufacturing, comprising an extension frame installed on the right side of the shearing table, wherein the extension frame is provided with a tension adaptive mechanism for adaptively adjusting the tension generated during the feeding of textiles, and the shearing table is provided with a shearing mechanism for automatically feeding and shearing textiles.

[0006] The tension adaptive mechanism includes a flexible spring installed in a strip groove on the extension frame, and a bearing seat is installed at the bottom of the flexible spring. A limiting sleeve is installed on the top wall of the strip groove and inside the flexible spring. A guide slide rod with its bottom connected to the bearing seat is slidably connected up and down inside the limiting sleeve. A feeding roller is rotatably connected between the two bearing seats.

[0007] Preferably, a traction roller is rotatably connected to the rotating hole opened on the extension frame, and an arc-shaped sliding surface is provided on the right edge of the shearing table. Limiting grooves are symmetrically opened on the left and right sides of the strip groove, and limiting sliders that slide up and down in the limiting grooves are installed on the left and right sides of the bearing seat.

[0008] Preferably, the shearing mechanism includes a U-shaped frame installed at the top right end of the shearing table, and an electric lifting rod is installed at the top center of the U-shaped frame. The bottom free end of the electric lifting rod passes through the U-shaped frame and is installed with a mounting plate. A cutter is installed at the bottom center of the mounting plate. Fixing components to prevent the textile from slipping during shearing are provided on both sides of the bottom of the mounting plate. A feeding component that automatically pulls the textile for feeding is provided on the shearing table.

[0009] Preferably, the fixing component includes a slide cylinder installed at the bottom of the mounting plate, and multiple compression springs are arrayed at the bottom of the mounting plate and inside the slide cylinder, with pressure blocks that slide vertically and vertically connected to the inner wall of the slide cylinder installed at the bottom of the compression springs.

[0010] Preferably, the feeding assembly includes guide rails installed on the front and rear sides of the shearing table, and an electric slider is slidably connected to the guide rails. An electric push rod is installed on the inner side of the electric slider, and clamping plates are installed on the free end of the bottom of the electric push rod and the bottom of the inner side of the electric slider.

[0011] Preferably, a shearing groove is provided on the shearing table directly below the cutter, and anti-slip ridges are provided on the pressure block and clamping plate.

[0012] By means of the above technical solution, this utility model provides an automatic tensioning and shearing device for textile manufacturing, which has at least the following beneficial effects:

[0013] 1. When the textile passes through the bottom of the feeding roller, it exerts a certain upward thrust on the feeding roller, pushing the bearing seat to move towards the top of the strip groove and compressing the flexible spring. If the textile experiences tension changes due to wrinkles or other issues, the tension can be released or tightened by the compressed flexible spring, thereby adapting to the tension changes of the textile during the feeding process.

[0014] 2. In this utility model, the mounting plate moves down and pushes the pressure block at its bottom to make contact with the textile first and press and fix it. As the mounting plate continues to move down, when the cutter cuts the textile, the pressure block is pushed and squeezed to compress the spring, thereby pressing the textile tighter and tighter, preventing the textile from being pulled and affecting the cutting effect.

[0015] 3. This utility model places one corner of the textile on the bottom clamping plate, then activates the electric push rod to push the clamping plate down, thereby clamping and fixing the textile. Then, the electric slider is activated simultaneously to slide to the left along the guide rail, completing the uniform pulling and feeding of the textile, thus avoiding wrinkles in the textile.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Addressing the issue that existing fixed tension adjustment mechanisms cannot adapt to slight tension changes in textiles during the feeding process, this embodiment provides an automatic tensioning and shearing device for textile manufacturing. Referring to Figures 1-6, this embodiment provides an automatic tensioning and shearing device for textile manufacturing that can automatically adjust the tension of the textile during the feeding process. This automatic tensioning and shearing device includes an extension frame 2 mounted on the right side of a shearing table 1. The extension frame 2 is equipped with a tension adaptive mechanism 3 that adaptively adjusts the tension generated during the textile feeding process. The shearing table 1 is equipped with a shearing mechanism 4 that automatically feeds and shears the textile. The shearing mechanism 4 feeds and shears the textile, and in conjunction with the tension adaptive mechanism 3, adaptively adjusts the tension of the textile during the feeding process, thereby preventing wrinkles in the textile and ensuring proper shearing.

[0032] Since the fixed tension adjustment mechanism in the prior art cannot adapt to the slight tension changes that occur in the textile during the feeding process, the device is equipped with a tension adaptive mechanism 3. The tension adaptive mechanism 3 includes a flexible spring 31 installed in a strip groove on the extension frame 2, and a bearing seat 32 is installed at the bottom of the flexible spring 31. A limiting sleeve 33 is installed on the top wall of the strip groove and inside the flexible spring 31. A guide slide rod 34 connected to the bearing seat 32 at its bottom is slidably connected up and down in the limiting sleeve 33. A feeding roller 35 is rotatably connected between the two bearing seats 32. When the textile passes through the bottom of the feeding roller 35, it generates a certain upward thrust on the feeding roller 35, pushing the bearing seat 32 to move towards the top of the strip groove and compressing the flexible spring 31. If the textile experiences tension changes due to wrinkles or other problems, the tension is released or tightened by the compressed flexible spring 31, thereby adaptively adjusting the tension of the textile during the feeding process.

[0033] A traction roller 36 is rotatably connected to the rotating hole on the extension frame 2, and an arc-shaped sliding surface is provided on the right edge of the shearing table 1. The traction roller 36 guides the textile to be flush with the shearing table 1, and the arc-shaped sliding surface prevents the edge of the shearing table 1 from scratching the textile. Limiting grooves are symmetrically provided on the left and right sides of the strip groove, and limiting sliders 37 that slide up and down in the limiting grooves are installed on the left and right sides of the bearing seat 32. When the bearing seat 32 moves up and down to adjust the tension, it drives the limiting sliders 37 on both sides to slide up and down in the limiting grooves, thereby preventing the bearing seat 32 from detaching from the strip groove.

[0034] The shearing mechanism 4 includes a U-shaped frame 41 installed at the top right end of the shearing table 1, and an electric lifting rod 42 is installed at the top center of the U-shaped frame 41. The bottom free end of the electric lifting rod 42 passes through the U-shaped frame 41 and is mounted on a mounting plate 43. A cutter 44 is installed at the bottom center of the mounting plate 43. Fixing components 45 are provided on both sides of the bottom of the mounting plate 43 to prevent the textile from slipping during shearing. A feeding component 46 is provided on the shearing table 1 to automatically pull the textile for feeding. When the electric lifting rod 42 is activated, it pushes the mounting plate 43 down until the cutter 44 at the bottom of the mounting plate 43 moves down to cut the textile.

[0035] Because the textile is pulled when the cutter 44 moves down to cut it, resulting in incomplete cutting, the device is also equipped with a fixing component 45. The fixing component 45 includes a slide cylinder 451 installed at the bottom of the mounting plate 43, and multiple compression springs 452 are arrayed at the bottom of the mounting plate 43 and inside the slide cylinder 451. Pressure blocks 453 are installed at the bottom of the compression springs 452 and are slidably connected to the inner wall of the slide cylinder 451. When the mounting plate 43 moves down, the pressure blocks 453 at its bottom first contact the textile and press and fix it. As the mounting plate 43 continues to move down, when the cutter 44 cuts the textile, the pressure blocks 453 are pushed and squeeze the compression springs 452, thereby pressing the textile tighter and tighter, preventing the textile from being pulled and affecting the cutting effect.

[0036] A shearing groove is provided on the shearing table 1 directly below the cutter 44. Anti-slip ridges are provided on the pressure block 453 and the clamping plate 464, which increases the friction with the textile and thus better fixes the textile.

[0037] Example 2

[0038] When manually pulling textiles for feeding, the fabric wrinkles and deformities occur due to the varying strength and movement speed of different workers. Therefore, based on Embodiment 1, as shown in Figures 1-6, the device also includes a feeding assembly 46. The feeding assembly 46 includes guide rails 461 installed on the front and rear sides of the shearing table 1, and an electric slider 462 is slidably connected to the guide rails 461. An electric push rod 463 is installed on the inner side of the electric slider 462, and clamping plates 464 are installed on the bottom free end of the electric push rod 463 and the bottom of the inner side of the electric slider 462. One corner of the textile is placed on the bottom clamping plate 464, and then the electric push rod 463 is activated to push the clamping plate 464 down, thereby clamping and fixing the textile. Then, the electric slider 462 is activated simultaneously to slide to the left along the guide rail 461, completing the uniform pulling and feeding of the textile and avoiding wrinkles.
