Description

Technical Field

[0001] The present invention relates to the technical field of fabric winding and tensioning, and particularly relates to a fabric tensioning device for clothing processing. Background Art

[0002] In the production and processing of clothing, fabric is an essential raw material. When the fabric goes through various processes, it needs to be wound and unwound. During the process of winding the fabric, the fabric may become skewed due to improper rotation speed of the winding device, uneven tension force of the tensioning mechanism, or deviation of the position of the guide roller. Moreover, when the fabric is elastic, the fabric may curl up on both sides during the tensioning and winding process.

[0003] Chinese Patent with Publication No. CN219238817U discloses a multifunctional deviation rectifying feeder, which includes a main body, a frame, a roller device, and an adjusting device. A frame is provided in the main body. The side end of the frame is electrically connected to a key. 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, and the side end of the data processor is electrically connected to a key. The adjusting device includes a slide rail, an induction guide rod, and a clamping plate. The induction guide rod is slidably connected to the slide rail, and the side end of the induction guide rod is electrically connected to the clamping plate. The fabric is flattened through the cooperation of the roller device and the adjusting device, so that the elastic fabric is not easily wrinkled. During the process of the fabric rolling, the adjusting device senses the edge of the material through the induction guide rod, and then controls the induction guide rod to move in the slide rail to adjust the edge position of the fabric. After the adjustment is completed, the clamping plate is used to clamp the edge of the fabric.

[0004] When adjusting the position of the fabric edge in the above technical solution, the edge of the fabric is adjusted by pushing the edge of the fabric through the induction guide rod. During the process of pushing the fabric to move, the fabric may be wrinkled, and the edge of the fabric may be curled, resulting in the clamping plate being unable to clamp the edge of the fabric after the adjustment, affecting the operation of the subsequent processes of the fabric. In addition, when the fabric is relatively thin and light, the induction guide rod may not be able to contact and push the fabric, losing the deviation rectifying effect.

[0005] Therefore, there is a need in the art for a fabric tensioning device for clothing processing to solve the above problems. Summary of the Invention

[0006] The present invention provides a fabric tensioning device for clothing processing, aiming to solve the problems that the related technology is prone to cause the fabric to be wrinkled and curled during deviation rectification of the fabric, and the deviation rectifying effect on thin and light fabrics 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;

[0008] 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.

[0009] 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.

[0010] 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] Preferably, a second pressing plate is provided above the cutting seam, a gap for the cloth to pass through is formed between the second pressing plate and the table top of the workbench, and the second pressing plate is provided with avoidance grooves corresponding to the upper and lower parts of the cutting seam.

[0012] 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.

[0013] Preferably, the first driving assembly includes a first motor, a first gear, and a second gear. The first motor is fixedly installed on the mounting shell. The second gear is fixedly connected to one end of each tension roller. A first gear is meshed between two adjacent second gears. The output end of the first motor is fixedly connected to one of the first gears.

[0014] Beneficial effects: By driving one of the first gears to rotate, the first gear drives the meshed second gear to rotate. The second gear drives other second gears to rotate synchronously through the first gear not connected to the first motor, so as to realize the synchronous and same-direction rotation of all the tension rollers in the same tensioning assembly, and ensure the adsorption and tensioning effects of the tension rollers on the fabric.

[0015] Preferably, the second driving assembly includes a second motor, a threaded rod, and a guide rod. The second motor is fixedly connected to the mounting frame. The threaded rod is fixedly connected to the output end of the second motor. The guide rod is fixedly connected to the mounting frame. The mounting shells of the two tensioning assemblies are respectively threadedly connected to the threaded rod, and the thread rotation directions of the threaded sections connected by the two mounting shells are opposite. The two mounting shells are slidably matched with the guide rod. The second motor drives the threaded rod to rotate, and the threaded rod drives the two mounting shells to move towards or away from each other.

[0016] Preferably, slide rails are symmetrically arranged on the workbench in the left-right direction. The mounting frame is slidably connected to the slide rails in the front-back direction. The third driving assembly includes a third motor, a third gear, and a rack. The third motor is fixedly connected to the mounting frame. The third gear is fixedly connected to the output end of the third motor. The rack is fixedly connected to the workbench. The third gear is meshed with the rack.

[0017] Preferably, an adsorption tube extending in the left-right direction is arranged on the workbench. The top of the adsorption tube is tangent to the plane of the workbench surface. An avoidance groove is formed on the workbench. A plurality of adsorption holes exposed at the avoidance groove are arranged at intervals in the left-right direction on the top of the adsorption tube. The adsorption tube is communicated with a third air extraction pump.

[0018] Beneficial effects: The adsorption tube adsorbs the fabric to be wound, so as to expose and temporarily fix the starting end of the fabric to be wound on the workbench. After the wound fabric is taken off by the staff, it is convenient to place the starting end of the fabric to be wound on the winding roller for winding.

[0019] Preferably, the cutting assembly includes a cutting knife and a mounting guide rail extending in the left-right direction. The mounting guide rail is slidably connected to the lower part of the workbench in the up-down direction. An automatic telescopic cylinder for driving the mounting guide rail to move up and down is arranged on the workbench. A mounting block and an automatic telescopic cylinder for driving the mounting block to move in the left-right direction are arranged on the mounting guide rail. The mounting block is fixedly connected with a fourth motor. The cutting knife is fixedly connected to the output end of the fourth motor.

[0020] Preferably, the detector is electrically connected to a controller. Electric control valves are respectively arranged on the pipelines connecting each tension roller to the first air extraction pump and on the pipelines connecting each tension roller to the second air extraction pump. The electric control valves are signal-connected to the controller. When the detector detects that the fabric is skewed, the controller controls the corresponding electric control valve to close.

[0021] Preferably, the first pressing plate is provided with a flat portion and inclined portions symmetrically distributed on both sides of the flat portion in the left-right direction. The inclined portions are inclined upward from the end close to the flat portion to the end far from the flat portion. The detector is a photoelectric sensor.

[0022] Beneficial effects: The inclined portions are beneficial for the tensioning assembly to smoothly push the fabric under the flat portion, so that the flat portion forms an extrusion on the gathered fabric.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The tension roller of the present invention flattens and tensions the positions on both sides of the fabric through the adsorption force of the suction holes on the fabric and the friction force between the tension roller and the fabric, avoiding wrinkles or curling at both sides of the fabric;

[0025] (2) When the detector of the present invention detects that the fabric is skewed, it can control the corresponding tension roller to disconnect from the first air extraction pump or the second air extraction 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 effect of pulling the fabric in the opposite direction of the skewed direction is achieved, thereby realizing the deviation correction of the fabric;

[0026] (3) The present invention realizes the deviation correction of the fabric by increasing the adsorption force and friction force of the tension roller on the fabric. When winding relatively thin and light fabrics, it can also achieve good deviation correction and winding effects, with strong adaptability;

[0027] (4) When the fabric needs to be cut, the tensioning assembly pushes the fabric to gather in the middle, and the two first pressing plates form an extrusion on the gathered fabric, avoiding the sliding of the fabric. The cutting assembly cuts the fabric gathered between the two first pressing plates, thereby forming a relatively flat cut, avoiding the phenomenon of skewed cut seams or pulling and thread breakage at the cut.

Detailed implementation manners

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] As Figures 1 to 7 shown, a fabric tensioning device for clothing processing according to the present invention includes 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 the fabric 3. Defining the length direction of the winding roller 2 as the left-right direction, two tensioning assemblies are symmetrically arranged on the workbench 1 along the left-right direction. The tensioning assembly includes a mounting shell 4 and three tensioning rollers 41 rotatably connected to the mounting shell 4 for pressing the fabric 3.

[0039] The tensioning rollers 41 extend in the front-rear direction and are arranged side by side in the left-right direction. Suction holes 42 are formed in the tensioning rollers 41. Each tensioning roller 41 of the tensioning assembly on the right side is respectively communicated with an air extraction pump I (not shown in the figure), and each tensioning roller 41 of the tensioning assembly on the left side is respectively communicated with an air extraction pump II (not shown in the figure), and electric control valves are respectively installed on the communicated pipelines. The air extraction pump I and the air extraction pump II have the same power. A driving assembly I for driving the tensioning rollers 41 to rotate and a detector 43 corresponding to each tensioning roller 41 are arranged 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.

[0040] Mounting grooves 44 adapted to the tensioning rollers 41 are formed at the bottom of the mounting shell 4. The tensioning rollers 41 are rotatably connected in the corresponding mounting grooves 44, and the bottom of the tensioning rollers 41 extends out of the mounting grooves 44 by a small distance. During the process of winding the fabric 3, if the fabric 3 does not deflect, the detection signals of the detectors 43 corresponding to all the tensioning rollers 41 are stable. The tensioning rollers 41 on the right side are all communicated with the air extraction pump I, and the tensioning rollers 41 on the left side are all communicated with the air extraction pump II. The driving assembly I drives the tensioning rollers 41 to rotate. The suction force of the tensioning rollers 41 on the fabric 3 through the suction holes 42 and the frictional force between the tensioning rollers 41 and the fabric 3 flatten and tension the positions on both sides of the fabric 3, avoiding wrinkles or curling on both sides of the fabric 3.

[0041] If the fabric 3 deflects to the left, the fabric 3 will move away from below 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 communication between the rightmost tensioning roller 41 and the air extraction pump I. Since the power of the air extraction pump I does not change at this time, the suction force of the air extraction pump I on the other two tensioning rollers 41 of the right tensioning assembly becomes larger. The suction force of the suction holes 42 of these two tensioning rollers 41 on the fabric 3 becomes larger, and the frictional force between the tensioning rollers 41 and the fabric 3 becomes larger. Thus, during the rotation of these two tensioning rollers 41 on the right side, the fabric 3 is pulled to the right side, realizing the deviation correction function of the fabric 3.

[0042] It can be understood that when the fabric 3 deflects to the right, the fabric 3 will move out from under the detector 43 corresponding to the leftmost tensioning roller 41. The detection signal of the detector 43 corresponding to the leftmost tensioning roller 41 will change. The controller controls the solenoid valve corresponding to the leftmost tensioning roller 41 to close according to the signal change. Then, the adsorption force and friction force of the other two tensioning rollers 41 of the left tensioning assembly on the fabric 3 also increase, realizing pulling the fabric 3 to the left and achieving the deviation correction effect on the fabric 3. Moreover, when the present invention corrects the deviation of the fabric 3, it will not cause axial extrusion on the fabric 3, improving the phenomenon of wrinkles and curling of the fabric 3 during the deviation correction process. In addition, the present invention can also correct the deviation of the fabric 3 with relatively thin and light fabric.

[0043] As Figure 5 and Figure 6 shown, the first driving assembly includes a first motor 5, a first gear 51 and a second gear 52. The first motor 5 is fixedly installed on the mounting shell 4. The second gear 52 is fixedly connected to one end of each tensioning roller 41. A first gear 51 is meshed between two adjacent second gears 52. The output end of the first motor 5 is fixedly connected to one of the first gears 51. By controlling the first motor 5 to drive the first gear 51 to rotate, the first gear 51 drives the second gear 52 to rotate, and the second gear 52 drives the corresponding tensioning roller 41 to rotate.

[0044] As Figure 1 , Figure 2 and Figure 7 shown, a cutting slot 11 and a cutting assembly located below the cutting slot 11 are provided on the workbench 1. Pressing plates 6 are symmetrically arranged on the front and rear sides of the cutting slot 11. A gap for the fabric 3 to pass through is formed between the pressing plates 6 and the tabletop of the workbench 1. The tensioning assembly is located between the two pressing plates 6. A second driving assembly for driving the two tensioning assemblies to move in the left - right direction is provided on the workbench 1.

[0045] After the fabric 3 is wound up, it is necessary to cut the fabric 3. Since the fabric 3 is still in a tensioned state during cutting, if cutting starts from one side of the fabric 3, it may cause the cutting seam to be skewed or the fabric 3 at the cut - off point to be pulled and de - wired. In the present invention, the second driving assembly drives the two tensioning assemblies to move towards each other, and drives the tensioning rollers 41 of the tensioning assembly to rotate in the reverse direction. The tensioning rollers 41 push the fabric 3 to converge towards the middle. The two pressing plates 6 form extrusion on the converged fabric 3 to prevent the fabric 3 from sliding. The cutting assembly cuts the fabric 3 converged between the two pressing plates 6, thereby forming a relatively flat cut.

[0046] As 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] like Figure 1 and Figure 3As shown in the figure, slide rails 12 are symmetrically arranged on the workbench 1 in the left-right direction. The mounting frame 8 is slidably connected to the slide rails 12 in the front-rear direction. The third driving assembly includes a third motor (not shown in the figure), a third gear (not shown in the figure), and a rack (not shown in the figure). The third motor is fixedly connected to the mounting frame 8. The third gear is fixedly connected to the output end of the third motor. The rack is fixedly connected to the workbench 1. The third gear meshes with the rack.

[0051] An adsorption tube 13 extending in the left-right direction is arranged on the workbench 1. The top of the adsorption tube 13 is tangent to the plane where the tabletop of the workbench 1 is located. An avoidance groove (not shown in the figure) is formed on the workbench 1. A plurality of adsorption holes 14 exposed at the avoidance groove are arranged at intervals in the left-right direction at the top of the adsorption tube 13. The adsorption tube 13 is communicated with a third air extraction pump.

[0052] After cutting is completed, the fabric 3 is still gathered in the middle position of the workbench 1 under the action of the first pressing plate 6 and the second pressing plate 7. Drive the two tensioning assemblies to move towards the middle fabric 3, and drive the tensioning rollers 41 of the two tensioning assemblies to rotate in the direction of pulling the fabric 3 towards the left and right sides. After the side of the fabric 3 enters below the tensioning rollers 41 of the two tensioning assemblies, the tensioning rollers 41 of the two tensioning assemblies unfold the fabric 3 towards the left and right sides, and then drive the two tensioning assemblies to reset.

[0053] Drive the mounting frame 8 to move towards the winding roller 2. The fabric 3 follows the movement of the mounting frame 8 under the adsorption of the air suction holes 42 on the tensioning rollers 41. Define the cut end of the wound fabric 3 as the end, and the cut end of the fabric 3 to be wound as the start. When the start of the fabric 3 crosses the avoidance groove on the workbench 1, control the second air extraction pump to work. The adsorption holes 14 on the adsorption tube 13 form adsorption on the fabric 3 to be wound. Control the first air extraction pump and the second air extraction pump corresponding to the tensioning assembly to stop operating. Then drive the mounting frame 8 to drive the tensioning assembly to reset. The fabric 3 to be wound will not follow the movement of the mounting frame 8 under the adsorption of the adsorption tube 13, so as to expose and temporarily fix the start of the fabric 3 to be wound on the workbench 1. After the staff removes the wound fabric 3, it is convenient to place the start of the fabric 3 to be wound on the winding roller 2 for winding.
