Description

Technical Field

[0001] The invention relates to the technical field of cloth winding and tensioning, and in particular to a cloth tensioning device for clothing processing. Background Art

[0002] In the production and processing of clothing, fabric is an indispensable raw material. When the fabric goes through each process, it needs to be rolled up and unrolled. In the process of rolling up the fabric, the fabric may be skewed due to improper speed of the winding device, uneven tensioning force of the tensioning mechanism or offset position of the guide roller. In addition, when the fabric is elastic, the edges of the fabric on both sides may curl upwards during the tensioning and rolling process.

[0003] The Chinese patent with the announcement number CN219238817U discloses a multifunctional deviation-correcting feeder, including a body, a frame, a roller device and an adjusting device. The body is provided with a frame, the side end of the frame is electrically connected to a button, the frame is electrically connected to the roller device and the adjusting device, the side end of the roller device is electrically connected to a data processor, the side end of the data processor is electrically connected to a button, and the adjusting device includes a slide rail, a sensing guide rod and a clamping plate, the slide rail is slidably connected to the sensing guide rod, and the side end of the sensing guide rod is electrically connected to the clamping plate. The fabric is flattened by the cooperation of the roller device and the adjusting device, so that the elastic fabric is not easy to wrinkle. During the rolling process of the fabric, the adjusting device senses the edge of the material through the sensing guide rod, and then controls the sensing guide rod to move in the slide rail to adjust the edge position of the fabric. After the adjustment, the clamping plate is used to clamp the edge of the fabric.

[0004] The above technical solution adjusts the position of the edge of the cloth by pushing the edge of the cloth through the sensing guide rod. In the process of pushing the cloth to move, the cloth may wrinkle and the edge of the cloth may curl, resulting in the inability of the clamping plate to clamp the edge of the cloth after the adjustment is completed, affecting the operation of subsequent processes of the cloth. In addition, when the cloth is relatively thin, the sensing guide rod may not be able to contact and push the cloth, and the correction effect is lost.

[0005] Therefore, the art needs a cloth tensioning device for clothing processing to solve the above problems. Summary of the invention

[0006] The present invention provides a cloth tensioning device for clothing processing, aiming to solve the problems in the related art that cloth is easily wrinkled and curled when being corrected, and the correction effect on thin and light cloth is poor.

[0007] A cloth tensioning device for clothing processing of the present invention comprises a workbench and a winding roller arranged on the workbench, wherein the length direction of the winding roller is defined as the left-right direction, two tensioning assemblies are symmetrically arranged on the workbench along the left-right direction, the tensioning assembly comprises a mounting shell and a plurality of tensioning rollers rotatably connected to the mounting shell for pressing the cloth, the tensioning rollers extend along the front-back direction and are arranged side by side along the left-right direction, suction holes are provided on the tensioning rollers, each tensioning roller of one tensioning assembly is respectively connected to a first suction pump, and each tensioning roller of another tensioning assembly is respectively connected to a second suction pump, a driving assembly 1 for driving the tensioning roller to rotate and a detector corresponding to each tensioning roller are arranged on the mounting shell, and after the detector corresponding to the tensioning roller detects that the cloth is deflected, the connection between the tensioning roller and the first suction pump or the second suction pump is closed; A cutting seam and a cutting assembly below the cutting seam are arranged on the workbench, pressing plates 1 are symmetrically arranged on the front and rear sides of the cutting seam, a gap for the cloth to pass through is formed between the pressing plate 1 and the table top of the workbench, the tensioning assembly is located between the two pressing plates 1, and a driving assembly 2 for driving the two tensioning assemblies to move in the left and right directions is arranged on the workbench.

[0008] Beneficial effect: The tensioning roller of the present invention flattens and tensions the positions of both sides of the cloth through the adsorption force of the suction hole on the cloth and the friction force between the tensioning roller and the cloth, thereby avoiding wrinkles or curling on both sides of the cloth. When the detector detects that the cloth is deflected, it can control the corresponding tensioning roller to disconnect from the vacuum pump one or the vacuum pump two, thereby increasing the adsorption force and friction force of other tensioning rollers in the same group on the cloth. As the tensioning roller rotates, the cloth is pulled in the opposite direction of the deflection direction, thereby achieving a deviation correction effect, and can adapt to the winding of relatively thin cloth. In addition, when cutting the cloth, a relatively smooth incision can be formed.

[0009] Preferably, the workbench is provided with a mounting frame and a driving component three for driving the mounting frame to move in the front-rear direction, the tensioning component is slidably connected to the mounting frame in the left-right direction, and the clamping plate is fixedly connected to the mounting frame.

[0011] Beneficial effect: When the cloth is gathered toward the middle, the second pressing plate also squeezes the gathered cloth. When cutting, the cutting assembly rises to the avoidance groove of the second pressing plate to cut the cloth, thereby improving the sliding of the cloth during the cutting process and further improving the flatness of the cloth cut.

[0012] Preferably, drive assembly 1 includes motor 1, gear 1 and gear 2, motor 1 is fixedly mounted on the mounting shell, gear 2 is fixedly connected to one end of each tensioning roller, gear 1 is meshed between two adjacent gears 2, and the output end of motor 1 is fixedly connected to one of the gears 1.

[0013] Beneficial effect: by driving one of the gears 1 to rotate, the gear 1 drives the meshing gear 2 to rotate, and the gear 2 drives the other gears 2 to rotate synchronously through the gear 1 which is not connected to the motor 1, so as to realize the synchronous and unidirectional rotation of all the tensioning rollers in the same tensioning assembly, thereby ensuring the adsorption and tensioning effect of the tensioning roller on the cloth.

[0015] Preferably, slide rails are symmetrically arranged on the workbench in the left-right direction, and the mounting frame is slidably connected to the slide rails in the front-back direction. The driving component three includes a motor three, a gear three and a rack. The motor three is fixedly connected to the mounting frame, the gear three is fixedly connected to the output end of the motor three, the rack is fixedly connected to the workbench, and the gear three is meshed with the rack.

[0016] Preferably, an adsorption tube extending in the left-right direction is provided on the workbench, the top of the adsorption tube is tangent to the plane where the table top of the workbench is located, an avoidance groove is provided on the workbench, and a plurality of adsorption holes exposed to the avoidance groove are provided on the top of the adsorption tube at intervals in the left-right direction, and the adsorption tube is connected to a vacuum pump three.

[0017] Beneficial effect: The adsorption tube is used to adsorb the cloth to be rolled, so that the beginning of the cloth to be rolled is exposed and temporarily fixed on the workbench, which makes it convenient for the staff to take down the rolled cloth and then place the beginning of the cloth to be rolled on the winding roller for rolling.

[0018] Preferably, the cutting assembly includes a cutting knife and a mounting rail extending in the left-right direction, the mounting rail is slidably connected to the bottom of the workbench in the up-down direction, and an automatic telescopic cylinder 1 for driving the mounting rail to move up and down is provided on the workbench, a mounting block and an automatic telescopic cylinder 2 for driving the mounting block to move in the left-right direction are provided on the mounting rail, the mounting block is fixedly connected to a motor 4, and the cutting knife is fixedly connected to the output end of the motor 4.

[0019] Preferably, the detector is electrically connected to the controller, and an electric control valve is respectively provided on the pipeline connecting each tensioning roller and the vacuum pump 1 and the pipeline connecting each tensioning roller and the vacuum pump 2.

[0021] Beneficial effect: The inclined portion is conducive to the tensioning assembly to smoothly push the cloth to the bottom of the straight portion, so that the straight portion squeezes the gathered cloth.

[0022] The beneficial effects of the present invention are: (1) The tensioning roller of the present invention flattens and tensions the positions of both sides of the cloth through the adsorption force of the suction holes on the cloth and the friction between the tensioning roller and the cloth, thereby preventing wrinkles or curling on both sides of the cloth; (2) When the detector detects that the fabric is deflected, the present invention can control the corresponding tension roller to be disconnected from the first or second vacuum pump, thereby increasing the adsorption force and friction force of other tension rollers in the same group on the fabric. As the tension roller rotates, the fabric is pulled in the opposite direction of the deflection direction, thereby achieving the function of correcting the fabric. (3) The present invention realizes the deviation correction of the cloth by increasing the adsorption force and friction force of the tension roller on the cloth. When winding relatively light and thin cloth, it can also achieve good deviation correction and winding effects and has strong adaptability; (4) When the cloth needs to be cut, the tensioning assembly pushes the cloth to gather in the middle, and the two pressing plates squeeze the gathered cloth to prevent the cloth from sliding. The cutting assembly cuts the cloth gathered between the two pressing plates, thereby forming a relatively smooth incision, avoiding the phenomenon of skewed cutting or pulling and derailing of the cloth at the incision.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 7 As shown, a fabric tensioning device for clothing processing of the present invention comprises a workbench 1 and a winding roller 2 rotatably connected to the workbench 1, a driving motor (not shown in the figure) is fixedly connected to the workbench 1, and the driving motor drives the winding roller 2 to wind up the fabric 3. The length direction of the winding roller 2 is defined as the left-right direction, and two tensioning assemblies are symmetrically arranged on the workbench 1 along the left-right direction, and the tensioning assemblies include a mounting shell 4 and three tensioning rollers 41 rotatably connected to the mounting shell 4 for pressing the fabric 3.

[0033] The tensioning roller 41 extends in the front-to-back direction and is arranged side by side in the left-to-right direction. An air suction hole 42 is provided on the tensioning roller 41. The tensioning rollers 41 of the tensioning assembly on the right are respectively connected to a vacuum pump 1 (not shown in the figure), and the tensioning rollers 41 of the tensioning assembly on the left are respectively connected to a vacuum pump 2 (not shown in the figure), and an electric control valve is installed on the connected pipes. The power of the vacuum pump 1 and the vacuum pump 2 is the same. A driving assembly 1 for driving the tensioning roller 41 to rotate and a detector 43 corresponding to each tensioning roller 41 are provided on the mounting shell 4. As an example, the detector 43 is a photoelectric sensor, and the detector 43 is electrically connected to a controller.

[0034] The bottom of the mounting shell 4 is provided with mounting grooves 44 adapted to the tensioning rollers 41. The tensioning rollers 41 are rotatably connected to the corresponding mounting grooves 44, and the bottom of the tensioning rollers 41 extends a small distance out of the mounting grooves 44. In the process of winding the cloth 3, if the cloth 3 is not deflected, the detection signals of the detectors 43 corresponding to all the tensioning rollers 41 are stable, the tensioning rollers 41 on the right are connected to the suction pump 1, and the tensioning rollers 41 on the left are connected to the suction pump 2. The driving component 1 drives the tensioning rollers 41 to rotate. The tensioning rollers 41 flatten and tension the positions on both sides of the cloth 3 through the adsorption force of the suction holes 42 on the cloth 3 and the friction between the tensioning rollers 41 and the cloth 3, so as to avoid wrinkles or curling on both sides of the cloth 3.

[0035] If the cloth 3 deviates to the left, the cloth 3 will be out of the detector 43 corresponding to the rightmost tensioning roller 41, and the detection signal of the detector 43 corresponding to the rightmost tensioning roller 41 will change. The controller controls the electric control valve corresponding to the rightmost tensioning roller 41 to close according to the signal change, so as to disconnect the connection between the rightmost tensioning roller 41 and the vacuum pump 1. Because the power of the vacuum pump 1 has not changed at this time, the suction force of the other two tensioning rollers 41 of the right tensioning assembly of the vacuum pump becomes larger, the suction force of the suction holes 42 of the two tensioning rollers 41 on the cloth 3 becomes larger, and the friction between the tensioning roller 41 and the cloth 3 becomes larger, thereby achieving the effect of pulling the cloth 3 to the right during the rotation of the two tensioning rollers 41 on the right, thereby achieving the effect of correcting the deviation of the cloth 3.

[0036] It is understandable that if the cloth 3 deflects to the right, the cloth 3 will be separated from the detector 43 corresponding to the leftmost tensioning roller 41, and the detection signal of the detector 43 corresponding to the leftmost tensioning roller 41 will change. The controller controls the electric control valve corresponding to the leftmost tensioning roller 41 to close according to the signal change, and the adsorption force and friction force of the other two tensioning rollers 41 of the left tensioning assembly on the cloth 3 will also increase, so that the cloth 3 is pulled to the left, and the deviation correction of the cloth 3 is achieved. Moreover, when the present invention corrects the deviation of the cloth 3, it will not form axial extrusion on the cloth 3, which improves the phenomenon of wrinkles and curling of the cloth 3 during the deviation correction process. In addition, the present invention can also correct the deviation of the cloth 3 with a relatively thin surface.

[0037] like Figure 5 and Figure 6 As shown, the driving assembly 1 includes a motor 15, a gear 151 and a gear 252. The motor 15 is fixedly mounted on the mounting housing 4. The gear 252 is fixedly connected to one end of each tension roller 41. A gear 151 is meshed between two adjacent gears 252. The output end of the motor 15 is fixedly connected to one of the gears 151. By controlling the motor 15 to drive the gear 151 to rotate, the gear 151 drives the gear 252 to rotate, and the gear 252 drives the corresponding tension roller 41 to rotate.

[0038] like Figure 1 , Figure 2 and Figure 7 As shown, the workbench 1 is provided with a cutting slit 11 and a cutting assembly located below the cutting slit 11. Pressing plates 1 6 are symmetrically arranged on the front and rear sides of the cutting slit 11, and a gap for the cloth 3 to pass through is formed between the pressing plates 1 6 and the table surface of the workbench 1. The tensioning assembly is located between the two pressing plates 1 6, and the workbench 1 is provided with a driving assembly 2 for driving the two tensioning assemblies to move in the left and right directions.

[0039] After the cloth 3 is rolled up, it is necessary to cut the cloth 3. Since the cloth 3 is still in a tensioned state during cutting, if cutting is started from one side of the cloth 3, the cut seam may be skewed or the cloth 3 may be pulled off the line at the cut. In the present invention, the two tensioning components are driven by the driving component 2 to move towards each other, and the tensioning roller 41 of the tensioning component is driven to rotate in the opposite direction. The tensioning roller 41 pushes the cloth 3 to gather toward the middle, and the two pressing plates 6 squeeze the gathered cloth 3 to prevent the cloth 3 from sliding. The cutting component cuts the cloth 3 gathered between the two pressing plates 6 to form a relatively smooth incision.

[0040] like Figure 1 and Figure 4As shown, the workbench 1 is provided with a mounting frame 8 and a driving assembly 3 for driving the mounting frame 8 to move in the front-back direction, the tensioning assembly is slidably connected to the mounting frame 8 in the left-right direction, and the clamping plate 1 6 is fixedly connected to the mounting frame 8. The driving assembly 2 includes a motor 2 9, a threaded rod 91 and a guide rod 92, the motor 2 9 is fixedly connected to the mounting frame 8, the threaded rod 91 is fixedly connected to the output end of the motor 2 9, the guide rod 92 is fixedly connected to the mounting frame 8, the mounting shells 4 of the two tensioning assemblies are respectively threadedly connected to the threaded rod 91, and the threaded sections connected to the two mounting shells 4 have opposite threaded directions, and the two mounting shells 4 are slidably matched with the guide rod 92. The motor 2 9 drives the threaded rod 91 to rotate, and the threaded rod 91 drives the two mounting shells 4 to move in the direction of approaching or moving away from each other.

[0041] like Figure 1 and Figure 7 As shown, a clamping plate 2 7 is arranged above the cutting slit 11, and a gap is formed between the clamping plate 2 7 and the table surface of the workbench 1 for the cloth 3 to pass through, and both ends of the clamping plate 2 7 are fixedly connected to the mounting frame 8. The clamping plate 1 6 is provided with a straight portion 61 and inclined portions 62 symmetrically distributed on both sides of the straight portion 61 along the left-right direction, and the inclined portion 62 is arranged upwardly inclined from one end close to the straight portion 61 to one end away from the straight portion 61. The structure of the clamping plate 2 7 is the same as that of the clamping plate 1 6, but the clamping plate 2 7 is provided with an avoidance through groove 71 corresponding to the upper and lower sides of the cutting slit 11.

[0042] like Figure 2 As shown, the cutting assembly includes a cutting knife 10 and a mounting rail 101 extending in the left-right direction, the mounting rail 101 is slidably connected to the bottom of the workbench 1 in the up-down direction, and the workbench 1 is provided with an automatic telescopic cylinder 1 (not shown in the figure) that drives the mounting rail 101 to move up and down, and the mounting rail 101 is provided with a mounting block 102 and an automatic telescopic cylinder 2 (not shown in the figure) that drives the mounting block 102 to move in the left-right direction. As an example, the automatic telescopic cylinder 1 and the automatic telescopic cylinder 2 are both electric telescopic cylinders. The mounting block 102 is fixedly connected to a motor 4 103, and the cutting knife 10 is fixedly connected to the output end of the motor 4 103.

[0043] When the cloth 3 is gathered toward the middle, the clamping plate 2 7 also squeezes the gathered cloth 3. During cutting, the cutting knife 10 is driven to rotate by the motor 4 103, and the mounting guide rail 101 is driven to move upward by the automatic telescopic cylinder 1. After the cutting knife 10 cuts upward and enters the avoidance groove 71 of the clamping plate 2 7, the automatic telescopic cylinder 2 is controlled to drive the mounting block 102 to move in the left and right directions to cut the cloth 3. The arrangement of the clamping plate 2 7 and the avoidance groove 71 improves the sliding phenomenon of the cloth 3 during the cutting process, and further improves the flatness of the cut of the cloth 3.

[0044] like Figure 1 and Figure 3As shown, the workbench 1 is symmetrically provided with slide rails 12 along the left-right direction, the mounting frame 8 is slidably connected to the slide rails 12 along the front-back direction, the driving component three includes a motor three (not shown in the figure), a gear three (not shown in the figure) and a rack (not shown in the figure), the motor three is fixedly connected to the mounting frame 8, the gear three is fixedly connected to the output end of the motor three, the rack is fixedly connected to the workbench 1, and the gear three is meshed with the rack.

[0045] An adsorption tube 13 extending in the left-right direction is provided on the workbench 1, the top of the adsorption tube 13 is tangent to the plane where the table surface of the workbench 1 is located, and an avoidance groove (not shown in the figure) is provided on the workbench 1. A plurality of adsorption holes 14 exposed at the avoidance groove are provided at intervals in the left-right direction on the top of the adsorption tube 13, and the adsorption tube 13 is connected to an air pump 3.

[0046] After the cutting is completed, the cloth 3 is still gathered in the middle of the workbench 1 under the action of the clamping plate 1 6 and the clamping plate 2 7, driving the two tensioning components to move towards the direction close to the middle cloth 3, and driving the tensioning rollers 41 of the two tensioning components to rotate in the direction of pulling the cloth 3 to the left and right sides. After the side of the cloth 3 enters under the tensioning roller 41, the tensioning rollers 41 of the two tensioning components unfold the cloth 3 to the left and right sides, and then drive the two tensioning components to reset.

[0047] The cloth 3 to be rolled up will not move with the mounting frame 8 under the adsorption of the air suction hole 42 on the tensioning roller 41, thereby exposing the starting end of the cloth 3 to be rolled up and temporarily fixing it on the workbench 1, so that the staff can take down the rolled up cloth 3 and then place the starting end of the cloth 3 to be rolled up on the winding roller 2 for winding.
