Description

Technical Field

[0001] The present application relates to the field of fabric shaping, and in particular to a fabric stretching machine and a stretching method thereof. Background Art

[0002] The fabric processing process needs to go through multiple steps such as cloth washing, softening, printing and dyeing. Among them, the stentering and setting machine is used to sort and set the fabric after impregnation in order to achieve the purpose of stabilizing the width of the fabric. The setting principle is that the fabric is immersed in the additive through the immersion tank and then pressed by the roller, and then it is set in the drying room. In this process, a stentering mechanism is needed to flatten the fabric and stretch it to a fixed width.

[0003] The cloth clip type is a structure that uses elastic clips or magnetic clips to clamp the edge of the cloth to achieve lateral traction, which can ensure the integrity of the cloth.

[0004] Regarding the above-mentioned related technologies, the stability of the method of simply clamping with cloth clips is poor, especially for smooth polyester fabrics or satin fabrics, the fabric is prone to fall off, thus affecting the shaping quality. Summary of the invention

[0005] In order to improve the stability of cloth clamping, the present application provides a cloth stretching machine and a stretching method thereof.

[0006] In a first aspect, the present application provides a fabric stretching machine, which adopts the following technical solution: A cloth stretching machine, comprising: A frame, on which two conveyor chains are arranged, a shaping machine box is arranged on the frame, the two conveyor chains both pass through the shaping machine box, and the ends of the two conveyor chains close to each other move in the same direction; The driving mechanism is arranged on the frame and drives the conveyor chains to move respectively; A clamping assembly is provided on the conveying chain and is used to clamp the side of the fabric; The anti-curling mechanism is arranged on the frame and located in front of the conveyor chain, and unfolds both sides of the fabric; The anti-skid coating mechanism is arranged on the frame and located in front of the conveyor chain, and applies anti-skid agent to both sides of the cloth to increase the friction between the cloth and the clamping assembly.

[0007] By adopting the above technical solution, the cloth passes through the anti-curling mechanism, which can unfold the two sides of the cloth; the cloth passes through the anti-skid coating mechanism, which can apply anti-skid agent to the two sides of the cloth; the cloth passes through the position between the two conveyor chains, and the two sets of driving mechanisms drive the two conveyor chains to move respectively, and the ends of the two conveyor chains close to each other move in the same direction, so that the multiple clamping components on the two conveyor chains clamp the two sides of the cloth, and clamp the cloth at the position where the anti-skid agent is applied on the cloth, and convey it to the shaping machine box, so that the shaping machine box can heat-set the cloth conveyed therein. Since the clamping component clamps the cloth at the position where the anti-skid agent is applied, the friction between the cloth and the clamping component can be increased, so that the cloth and the conveyor chain are not easy to move relative to each other, thereby improving the accuracy of heat setting of the shaping machine box.

[0008] Optionally, the clamping assembly includes a mounting frame arranged on the top of the conveyor chain, a receiving plate arranged on one side of the bottom of the mounting frame, a guide rod arranged on the mounting frame, a clamping plate slidably sleeved on the guide rod and cooperating with the receiving plate, and a downward pressing elastic member arranged between the mounting frame and the clamping plate and used to press down the clamping plate, the clamping plate cooperates with the receiving plate and clamps the side of the cloth, static guide blocks are arranged on the frame and at the opening and closing position of the clamping assembly, and a dynamic guide block cooperating with the static guide block is arranged on the clamping plate, and when the dynamic guide block passes through the static guide block, the clamping plate is guided to a state separated from the receiving plate, and the downward pressing elastic member is always in a compressed state.

[0009] By adopting the above technical solution, when the clamping assembly moves to the position where the cloth needs to be clamped, the dynamic guide block will pass through the static guide block. Under the guidance of the static guide block, the clamping plate can be moved upward and guided to a state of being separated from the receiving plate, and the lower elastic member can be further compressed. Then, as the conveyor chain continues to move, the cloth can be located between the receiving plate and the clamping plate. After the dynamic guide block is separated from the static guide block, the clamping plate can move downward under the elastic force of the lower elastic member, so that the clamping plate and the receiving plate can clamp the cloth.

[0010] Optionally, the anti-slip paint mechanism includes two paint racks arranged on a frame and located in front of a conveyor chain, a paint roller rotatably arranged in the paint rack, a paint driving component for driving the paint roller to rotate, a supply box for supplying paint to the paint roller, and a driven roller rotatably arranged in the paint rack and located above the paint roller through an adjusting component, a space for the cloth to pass through is reserved between the paint roller and the driven roller, and the bottom of the paint roller is immersed in the supply box.

[0011] By adopting the above technical solution, both sides of the cloth are respectively located between the paint roller and the driven roller. The paint driving member drives the paint roller to rotate, so that the paint roller applies the anti-slip agent in the supply box to the bottom position of one side of the cloth to increase the friction between the cloth and the clamping assembly.

[0012] Optionally, a UV curing lamp located on one side of the paint roller is provided in the paint rack, and the UV curing lamp is used to cure the position on the bottom of the cloth coated with the anti-slip agent. A constant temperature heating plate is provided in the paint rack.

[0013] By adopting the above technical solution, the UV curing lamp can provide UVA light source and accelerate the curing of the anti-slip agent, and the constant temperature heating plate can provide a temperature of 60°C, thereby heating the anti-slip agent on the surface of the fabric to achieve the curing of the anti-slip agent in a short time.

[0014] Optionally, the adjustment component includes a limit groove opened on the inner side of the paint rack, a limit block slidably connected to the limit groove, a driven shaft arranged on one side of the limit block, and an adjustment spring arranged in the limit groove and connected to the limit block, and the driven roller is rotatably arranged on the outside of the driven shaft.

[0015] By adopting the above technical solution, since the adjustment spring can provide downward pressing elastic force to the limit block, the driven roller can be driven close to the paint roller to increase the friction between the cloth and the paint roller and the driven roller respectively.

[0016] Optionally, a nozzle is provided inside the paint rack and below the cloth, the nozzle faces the cloth, and a plurality of vertically arranged spreading wheels are rotatably provided inside the paint rack, and the spreading wheels are staggered with the paint roller and the driven roller, respectively.

[0017] By adopting the above technical solution, the nozzle sprays gas to the bottom of the cloth and the position where the anti-slip agent is applied, which can improve the flow of hot air inside the paint rack to improve the uniformity of heating. When the cloth drives the left and right material spreading wheels to rotate, it can play an expanding role on both sides of the cloth.

[0018] Optionally, the anti-curling mechanism includes two flattening rollers rotatably disposed on a frame, and the two flattening rollers are respectively located at the front and rear sides of the anti-slip coating mechanism.

[0019] By adopting the above technical solution, since the surface of the flattening roller is provided with two sections of opposite guiding lines, the two sides of the cloth are spread out, making it difficult for the cloth to curl.

[0020] Optionally, a sliding rod is provided at one end of the driven shaft away from the limiting block, and the sliding rod slides through the paint rack.

[0021] By adopting the above technical solution, the sliding rod can limit the end of the driven shaft away from the limit block, so that the force on both ends of the driven shaft is more uniform.

[0022] Optionally, the driving mechanism includes two sprockets rotatably disposed on a frame and a main driving member for driving one of the sprockets to rotate, and the two sprockets are respectively engaged with a conveying chain.

[0023] By adopting the above technical solution, the output end of the main driving component drives one of the sprockets to rotate, and with the cooperation of the other sprocket, the conveyor chain can move.

[0024] In a second aspect, the present application provides a stretching method of a fabric stretching machine, which adopts the following technical solution. The stretching method comprises the following steps: S1: The fabric first passes through the flattening roller located at the front side, and drives the flattening roller to rotate, so that both sides of the fabric are spread out; S2: The fabric passes through the position between the coating roller and the driven roller, and the coating driving member drives the coating roller to rotate, so that the coating roller applies the anti-slip agent in the feed box to the bottom position of one side of the fabric, and under the action of the constant temperature heating plate and the UV curing lamp, the anti-slip agent on the surface of the fabric is cured, and then the fabric passes through the flattening roller at the rear side; S3: When the cloth passes the position between the two conveyor chains, under the guidance of the static guide block on the front side, the clamping plate can be driven to move upward through the dynamic guide block, so that the cloth can move to the position between the clamping plate and the receiving plate. After that, the static guide block is separated from the dynamic guide block, and the clamping plate is pressed down by the downward-pressing elastic member and cooperates with the receiving plate to clamp the position where the anti-slip agent is applied on the cloth; S4: When the moving guide block moves to the position of the static guide block at the rear side, under the guidance of the static guide block at the rear side, the clamping plate can be driven upward by the moving guide block, and the cloth can be separated from the position between the receiving plate and the clamping plate.

[0025] By adopting the above technical solution, the coating roller applies the anti-slip agent in the feed box to the bottom position of one side of the cloth to increase the friction between the cloth and the clamping assembly, making it difficult for the cloth and the conveyor chain to move relative to each other, thereby improving the accuracy of heat setting in the setting machine box.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The clamping component is clamped at the position where the anti-slip agent is applied on the fabric, which can increase the friction between the fabric and the clamping component, making it difficult for the fabric and the conveyor chain to move relative to each other, thereby improving the accuracy of heat setting in the setting cabinet; 2. The UV curing lamp can provide UVA light source and accelerate the curing of the anti-slip agent, and the constant temperature heating plate can provide a temperature of 60°C to heat the anti-slip agent on the surface of the fabric to achieve the curing of the anti-slip agent in a short time; 3.

[0029] The following is combined with Figures 1 to 7 This application is described in further detail.

[0030] The present application embodiment discloses a cloth stretching machine. Figure 1 and Figure 2The fabric stretching machine includes a frame 1, a driving mechanism 2, a clamping assembly 3, an anti-curling mechanism 4 and an anti-slip coating mechanism 5. A shaping chassis 11 is installed on the frame 1. Both ends of the shaping chassis 11 are provided with square openings for fabric to pass through. The shaping chassis 11 can heat shape the fabric transported therein, and the shaping chassis 11 is a prior art. A traction structure is installed on the rear side of the shaping chassis 11, and the traction structure is used to provide power for fabric movement. The traction structure is a prior art and will not be described in detail here.

[0031] The driving mechanism 2 is mounted on the frame 1. The driving mechanism 2 is arranged in two groups, and each group of the driving mechanism 2 is equipped with a conveyor chain 6. The two conveyor chains 6 pass through the shaping machine box 11 through the square opening, and the ends of the two conveyor chains 6 that are close to each other can move in the same direction. The clamping assembly 3 is mounted on the conveyor chain 6, and a plurality of clamping assemblies 3 are arranged along the length direction of the conveyor chain 6. The clamping assembly 3 can clamp the side of the cloth. The anti-curling mechanism 4 is mounted on the frame 1 and is located in front of the conveyor chain 6. The anti-curling mechanism 4 can unfold both sides of the cloth. The anti-slip coating mechanism 5 is mounted on the frame 1 and is located in front of the conveyor chain 6. The anti-slip coating mechanism 5 can apply anti-slip agent to both sides of the cloth to increase the friction between the cloth and the clamping assembly 3.

[0032] Under the action of the traction structure, the cloth moves and passes through the anti-curling mechanism 4, which can unfold the two sides of the cloth to prevent the two sides of the cloth from curling. The cloth passes through the anti-skid coating mechanism 5, which can apply anti-skid agent to the two sides of the cloth to increase the friction between the cloth and the clamping component 3. The cloth passes the position between the two conveying chains 6, and the two sets of driving mechanisms 2 drive the two conveying chains 6 to move respectively, and the two conveying chains 6 move in the same direction at one end close to each other, so that the multiple clamping components 3 on the two conveying chains 6 clamp the two sides of the cloth, and clamp the position where the anti-skid agent is applied on the cloth, and transport it to the setting machine box 11, so that the setting machine box 11 can heat-set the cloth transported therein. Since the clamping component 3 is clamped at the position where the anti-skid agent is applied on the cloth, the friction between the cloth and the clamping component 3 can be increased, so that the cloth and the conveying chain 6 are not easily moved relative to each other, thereby improving the accuracy of heat setting of the setting machine box 11.

[0033] Preferably, the anti-curling mechanism 4 includes two flattening rollers 41. Both of the two flattening rollers 41 rotate horizontally on the frame 1, and the two flattening rollers 41 are respectively located on the front and rear sides of the anti-slip coating mechanism 5. It should be noted that the fabric first passes through the flattening roller 41 on the front side of the anti-slip coating mechanism 5 and drives the flattening roller 41 to rotate. Since two sections of opposite guiding纹路 are provided on the surface of the flattening roller 41, the two sides of the fabric are unfolded, making it difficult for the fabric to curl, which facilitates the subsequent anti-slip coating mechanism 5 to apply anti-slip agent to the edges of the fabric. After the anti-slip coating mechanism 5 applies the anti-slip agent to the edges of the fabric and the anti-slip agent cures, the fabric passes through the flattening roller 41 on the rear side of the anti-slip coating mechanism 5, and the fabric is unfolded again, which facilitates the subsequent clamping assembly 3 to clamp the edges of the fabric.

[0034] Referring to Figure 3 , further, the anti-slip coating mechanism 5 includes a coating rack 51, a coating roller 52, a coating driving member 53, a feeding box 54, and a driven roller 55. There are two coating racks 51, and both of the two coating racks 51 are installed on the frame 1, and both of the two coating racks 51 are located at the position between the two flattening rollers 41. The cross-section of the coating rack 51 is in a "U" shape, and the openings of the two coating racks 51 are arranged facing each other. The length direction of the coating rack 51 is parallel to the moving direction of the fabric. The coating roller 52 is rotatably connected to the front side position inside the coating rack 51. The coating driving member 53 is installed outside the coating rack 51 and corresponding to the position of the coating roller 52, and the output end of the coating driving member 53 is fixed to one end of the coating roller 52, so that the coating driving member 53 can drive the coating roller 52 to rotate. An adjusting assembly 56 is installed at the position diagonally above the coating roller 52 inside the coating rack 51. The driven roller 55 is rotatably connected to the inside of the coating rack 51 through the adjusting assembly 56, and the driven roller 55 is located directly above the coating roller 52. A space for the fabric to pass through is left between the coating roller 52 and the driven roller 55. The feeding box 54 is installed inside the coating rack 51 and below the coating roller 52. The feeding box 54 contains anti-slip agent, and the bottom of the coating roller 52 is immersed in the anti-slip agent in the feeding box 54. In this embodiment, the anti-slip agent can be an epoxy adhesive of Waen®UV451.

[0035] After the fabric passes through the front flattening roller 41, it will pass through the position between the two coating racks 51, and both sides of the fabric are respectively located at the positions between the coating roller 52 and the driven roller 55. The coating driving member 53 drives the coating roller 52 to rotate, so that the coating roller 52 applies the anti-slip agent in the feeding box 54 to the bottom position of one side of the fabric to increase the friction between the fabric and the clamping assembly 3, and then the fabric passes through the flattening roller 41 on the rear side.

[0036] Referring to Figure 3 and Figure 4Preferably, a UV curing lamp 511 is installed at the bottom of the paint rack 51, and the length direction of the UV curing lamp 511 is parallel to the length direction of the paint rack 51, and the UV curing lamp 511 is located obliquely below the paint roller 52. A constant temperature heating plate 512 is installed at the bottom of the paint rack 51, and the length direction of the constant temperature heating plate 512 is parallel to the length direction of the UV curing lamp 511, and the constant temperature heating plate 512 is also located obliquely below the paint roller 52.

[0037] The UV curing lamp 511 can provide a UVA light source with a wavelength between 320nm and 420nm. The UV curing lamp 511 can irradiate the position on the bottom of the fabric where the anti-slip agent is applied and accelerate the curing of the anti-slip agent. The constant temperature heating plate 512 can provide a temperature of 60°C, thereby heating the anti-slip agent on the surface of the fabric to achieve the curing of the anti-slip agent in a short time.

[0038] Furthermore, a nozzle 513 is installed inside the paint rack 51 and below the cloth, and a plurality of nozzles 513 are arranged along the length direction of the paint rack 51 , and the nozzles 513 are inclined toward the cloth.

[0039] Gas is delivered to the nozzle 513 through an external air pipe, so that the nozzle 513 sprays the gas obliquely upward to the bottom of the cloth and the position coated with the anti-slip agent. This can not only improve the flow of hot air inside the paint rack 51 to improve the uniformity of heating, but also have an outward blowing effect on the cloth, so that the cloth can be better unfolded.

[0040] In addition, a plurality of material spreading wheels 514 arranged vertically are rotatably connected to the inner side of the paint rack 51. The plurality of material spreading wheels 514 are all located at the rear side of the paint roller 52 and the driven roller 55, and the material spreading wheels 514 are staggered left and right with respect to the paint roller 52 and the driven roller 55, respectively.

[0041] Since there is space for the cloth to pass through between the upper and lower material spreading wheels 514, the side of the cloth can pass through, and compared with the coating roller 52 and the driven roller 55, the material spreading wheel 514 is closer to the middle of the cloth, so that the upper and lower material spreading wheels 514 can contact the cloth without contacting the position where the anti-slip agent is applied to the bottom of the cloth, so as not to easily affect the curing of the anti-slip agent. In addition, since there are material spreading lines on the outer side of the material spreading wheels 514, and the material spreading lines of the material spreading wheel 514 on the left side of the cloth are opposite to the material spreading lines of the material spreading wheel 514 on the right side of the cloth, and the material spreading lines of the material spreading wheel 514 located above the cloth are opposite to the material spreading lines of the material spreading wheel 514 located below the cloth, when the cloth drives the left and right material spreading wheels 514 to rotate, it can play a spreading role on both sides of the cloth.

[0042] Reference Figure 4 and Figure 5, Preferably, the adjusting assembly 56 includes a limiting groove 561, a limiting block 562, a driven shaft 563, and an adjusting spring 564. The limiting groove 561 is vertically formed inside the paint rack 51 and corresponds to the position of the driven roller 55. The limiting block 562 is slidably connected in the limiting groove 561. The driven shaft 563 is horizontally fixed to one end of the limiting block 562 away from the limiting groove 561. The driven roller 55 is rotatably connected to the outside of the driven shaft 563. The adjusting spring 564 is located in the limiting groove 561, and both ends of the adjusting spring 564 are connected to the inner wall of the limiting groove 561 and the limiting block 562 respectively.

[0043] Since the adjusting spring 564 can provide a downward pressing elastic force to the limiting block 562, it can drive the driven roller 55 closer to the paint roller 52, so as to increase the friction between the fabric and the paint roller 52 and the driven roller 55 respectively, enabling the paint roller 52 to more smoothly apply the anti-slip agent to the bottom of the fabric and also being able to convey the fabric more stably.

[0044] Furthermore, a sliding rod 565 is vertically fixed to one end of the driven shaft 563 away from the limiting block 562, and the sliding rod 565 slidably penetrates through the paint rack 51. Since the sliding rod 565 is slidably connected to the paint rack 51, the sliding rod 565 can play a limiting role on one end of the driven shaft 563 away from the limiting block 562, making the forces on both ends of the driven shaft 563 more uniform, so as to improve the stability of the driven roller 55 during rotation, and thus can convey the fabric more stably.

[0045] Refer to Figure 6 , Preferably, the clamping assembly 3 includes a mounting frame 31, a receiving plate 32, a guide rod 33, a clamping plate 34, and a downward pressing elastic member 35. The mounting frame 31 is fixed to the top of a certain link plate of the conveying chain 6. The cross-section of the mounting frame 31 is in a "U" shape. The receiving plate 32 is horizontally fixed to one side of the bottom of the mounting frame 31, and the receiving plate 32 faces the periphery of the conveying chain 6. The guide rod 33 is vertically fixed inside the mounting frame 31. The clamping plate 34 is slidably sleeved on the outside of the guide rod 33. The clamping plate 34 is located above the receiving plate 32. The downward pressing elastic member 35 is sleeved on the outside of the guide rod 33, and the top end of the downward pressing elastic member 35 is connected to the inner top surface of the mounting frame 31. The bottom end of the downward pressing elastic member 35 is connected to the top of the clamping plate 34, and the downward pressing elastic member 35 is always in a compressed state. The clamping plate 34 and the receiving plate 32 cooperate to clamp the side of the fabric. In this embodiment, the downward pressing elastic member 35 is a spring.

[0046] Refer to Figure 6 and Figure 7A moving guide block 36 is fixed above the clamping plate 34. The moving guide block 36 faces the periphery of the conveying chain 6. The bottom surface of the moving guide block 36 is set as an inclined surface. In the forward direction of the conveying chain 6, the inclined surface of the bottom of the moving guide block 36 is higher in the front and lower in the back. Static guide blocks 37 are installed on the frame 1 and at the position where the clamping plate 34 is opened and closed. It should be noted that the ends of the two conveying chains 6 that are close to each other are the clamping positions, and the static guide blocks 37 are located at the clamping positions of the conveying chains 6 and are at the turning position. The static guide blocks 37 are inclined and smoothly transitioned sheet structures. In the forward direction of the conveying chain 6, the end of the static guide block 37 close to the forward direction of the conveying chain 6 is set as a high point, and the end of the static guide block 37 away from the forward direction of the conveying chain 6 is set as a low point.

[0047] When the clamping assembly 3 moves to the clamping position, the moving guide block 36 will pass the static guide block 37. Since the moving guide block 36 cooperates with the static guide block 37, the clamping plate 34 can be moved upward under the guidance of the static guide block 37, and the clamping plate 34 is guided to a state of separation from the receiving plate 32, and the lower elastic member is further compressed. Then, as the conveying chain 6 continues to move, the cloth can be located between the receiving plate 32 and the clamping plate 34. After the moving guide block 36 is separated from the static guide block 37, the clamping plate 34 can move downward under the elastic force of the lower elastic member, so that the clamping plate 34 and the receiving plate 32 can clamp the cloth. Similarly, when the clamping assembly 3 moves to the static guide block 37 at the rear side, the moving guide block 36 can move the clamping plate 34 upward under the guidance of the static guide block 37, and guide the clamping plate 34 to a state of separation from the receiving plate 32, thereby completing the separation of the cloth from the clamping assembly 3.

[0048] Reference Figure 2 Further, the driving mechanism 2 includes two sprocket wheels 21 and a main driving member 22. The two sprocket wheels 21 are rotatably connected to the frame 1, and the two sprocket wheels 21 are respectively engaged with the conveying chain 6. The main driving member 22 is installed on the frame 1, and the output end of the main driving member 22 is fixed to one of the sprocket wheels 21, so that the main driving member 22 can drive one of the sprocket wheels 21 to rotate. In this embodiment, the main driving member 22 is a servo motor.

[0049] The output end of the main driving member 22 drives one of the sprocket wheels 21 to rotate, and with the cooperation of the other sprocket wheel 21 , the conveying chain 6 can be moved, and the clamping assembly 3 on the conveying chain 6 can be driven.

[0050] The embodiment of the present application also discloses a stretching method of a cloth stretching machine, the stretching method comprising the following steps: S1: The fabric first passes through the flattening roller 41 located at the front side, and drives the flattening roller 41 to rotate, so that both sides of the fabric are spread out; S2: The cloth passes through the position between the coating roller 52 and the driven roller 55, and the coating driving member 53 drives the coating roller 52 to rotate, so that the coating roller 52 applies the anti-slip agent in the feeding box 54 to the bottom position of one side of the cloth, and under the action of the constant temperature heating plate 512 and the UV curing lamp 511, the anti-slip agent on the surface of the cloth is cured, and then the cloth passes through the flattening roller 41 located at the rear side; S3: When the cloth passes the position between the two conveyor chains 6, under the guidance of the static guide block 37 on the front side, the clamping plate 34 can be driven to move upward through the dynamic guide block 36, so that the cloth can move to the position between the clamping plate 34 and the receiving plate 32, and then the static guide block 37 is separated from the dynamic guide block 36, and the clamping plate 34 is pressed down by the downward pressure elastic member 35, and cooperates with the receiving plate 32 to clamp the position where the anti-slip agent is applied on the cloth; S4: When the movable guide block 36 moves to the position of the static guide block 37 on the rear side, under the guidance of the static guide block 37 on the rear side, the clamping plate 34 can be driven upward by the movable guide block 36, and the cloth can be separated from the position between the receiving plate 32 and the clamping plate 34. After the cloth is heat-set, the part of the cloth coated with the anti-slip agent needs to be cut off.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
