Abstract

This utility model relates to the technical field of fabric processing, specifically a textile fabric flattening device, including a worktable and a receiving frame installed on the worktable. A first limiting roller and a second limiting roller are sequentially arranged along the fabric conveying direction. A parallel linkage assembly capable of contacting the fabric is provided on the receiving frame. The parallel linkage assembly is controlled by a reciprocating drive component on the receiving frame to reciprocate relative to the worktable. This utility model, by controlling the parallel linkage assembly to perform reciprocating movement of the fabric, flattens the fabric when moving along the fabric conveying direction, and when moving along the opposite direction, controls the first limiting roller to release the fabric from its fixation via a unidirectional transmission component, causing the first and second conveying rollers to separate from the fabric.

Description

Technical Field

[0001] This utility model relates to the technical field of fabric processing, specifically a fabric flattening device. Background Technology

[0002] A textile fabric flattening device is a piece of equipment used to process textile fabrics. Its main function is to flatten, arrange, and optimize the fabric through specific technical means to improve its smoothness, reduce wrinkles and creases, and enhance the quality and efficiency of subsequent processing. These devices have wide applications in the textile industry, including but not limited to flattening, wrinkle removal, ironing, and dust removal.

[0003] Existing textile fabric flattening devices use flattening blocks to flatten the fabric. After flattening a portion of the fabric, the flattening block needs to be separated from the fabric, and then the conveying mechanism needs to be controlled to transport the fabric away. The flattened fabric is then transported to the bottom of the flattening block, and the flattening block needs to be controlled to contact the fabric again. Multiple drive sources need to be controlled simultaneously to complete a series of automated actions, making the operation cumbersome and the equipment requirements high. Summary of the Invention

[0004] The purpose of this invention is to provide a fabric flattening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A textile fabric flattening device includes a worktable and a receiving frame installed on the worktable. A first limiting roller and a second limiting roller are arranged sequentially along the conveying direction of the fabric, and the first limiting roller and the second limiting roller are fixedly connected.

[0007] The receiving frame is provided with a parallel link assembly that can abut against the fabric. The parallel link assembly is controlled by a reciprocating drive component on the receiving frame to reciprocate relative to the worktable. When the parallel link assembly deflects in the opposite direction of the fabric conveying direction, the parallel link assembly generates a force away from the fabric and controls the first limiting roller to release the fabric fixation through a one-way transmission component.

[0008] The textile fabric flattening device described above: the reciprocating drive component includes a drive shaft rotatably mounted on the receiving frame, one end of the drive shaft is driven to rotate by a motor mounted on the receiving frame, and a rotating plate is provided on the other end, with a protruding post installed at the eccentric position of the rotating plate;

[0009] It also includes a push rod, on which a groove is formed for the insertion and sliding adaptation of a protrusion, and the end of the push rod away from the protrusion is connected to a deflector on the receiving frame.

[0010] As described above, the textile fabric flattening device includes a deflecting shaft rotatably mounted on the receiving frame, a connecting plate hinged to the push rod is fixed between the two deflecting shafts, and deflecting rods are symmetrically sleeved on the deflecting shafts. A limiting groove is provided along the length direction of the deflecting rods and is slidably connected to the parallel connecting rod assembly.

[0011] As described above, the textile fabric flattening device includes a parallel linkage assembly comprising symmetrically arranged hinge plates, a movable shaft rotatably arranged between the two hinge plates, and both ends of the movable shaft passing through the hinge plates and inserted into the limiting groove for sliding engagement with the limiting groove.

[0012] It also includes elastic pressing members arranged in parallel on the hinge plate, one end of which is hinged to the hinge plate.

[0013] As described above, the textile fabric flattening device includes an insert sleeve plate, one end of which is hinged to the hinge plate, and the other end has an embedded groove. A pressure plate is slidably disposed in the embedded groove, and the end of the pressure plate away from the insert sleeve plate can abut against the fabric.

[0014] It also includes a spring disposed in the recessed groove, one end of the spring abutting against the inner end of the recessed groove, and the other end abutting against the pressure plate.

[0015] As described above, the textile fabric flattening device has symmetrical and rotatably positioned limit posts at both ends of the hinge plate, and a support plate is installed on the receiving frame. A slider fixed to the limit posts is slidably arranged inside the support plate.

[0016] As described above, the textile fabric flattening device includes a unidirectional transmission component comprising a transmission shaft rotatably mounted on the receiving frame, the transmission shaft being connected to the deflection shaft via a ratchet assembly, and the transmission shaft being connected to a connecting shaft rotatably mounted on the receiving frame via a belt, and the rotation of the connecting shaft being able to control a lifting component mounted on the receiving frame.

[0017] The textile fabric flattening device described above: the lifting component includes an extrusion shaft rotatably mounted on the receiving frame, the extrusion shaft is connected to the connecting shaft through a bevel gear set, and an inclined groove is formed on the extrusion shaft;

[0018] It also includes a lifting cylinder arranged axially along the extrusion shaft. A cylindrical cavity is formed in one end of the lifting cylinder, and a ball bearing adapted to the inclined groove is movably arranged on the inner wall of the cylindrical cavity. The other end is rotatably connected to the first limiting roller.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] When the fabric is laid flat on the worktable, the reciprocating drive unit controls the relative movement of the parallel linkage assembly on the worktable. As the parallel linkage assembly moves along the fabric conveying direction, the end of the parallel linkage assembly that contacts the fabric is subjected to a downward force, ensuring that the parallel linkage assembly and the fabric are always in contact. This effectively removes wrinkles and uneven areas from the fabric surface, making the fabric smoother. During the reset process after the parallel linkage assembly reaches the end of its stroke, the unidirectional transmission unit drives the first and second limit rollers to reciprocate, releasing the limiting work on the fabric. At the same time, the flattened fabric is conveyed away by the conveying rollers, while the unflattened fabric is conveyed to the lower end of the parallel linkage assembly. When the parallel linkage assembly returns to the origin of its stroke, the first and second limit rollers resume limiting the fabric again, awaiting the next flattening operation, further improving the fabric flattening efficiency.

[0029] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0030] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0032] Please see Figures 1-7 In this embodiment of the utility model, a textile fabric flattening device includes a workbench 1 and a receiving frame 2 installed on the workbench 1. A first limiting roller 4 and a second limiting roller 5 are arranged sequentially along the conveying direction of the fabric, and the first limiting roller 4 and the second limiting roller 5 are fixedly connected.

[0033] The receiving frame 2 is provided with a parallel link assembly that can abut against the fabric. The parallel link assembly is controlled by a reciprocating drive component on the receiving frame 2 to reciprocate relative to the worktable 1. When the parallel link assembly reciprocates in the opposite direction of the fabric conveying direction, the parallel link assembly generates a force away from the fabric and controls the first limiting roller 4 to release the fabric fixation through a one-way transmission component.

[0034] It should be noted that: a conveying roller 3 is rotatably arranged on the worktable 1 along the conveying direction of the fabric, and the rotation of the conveying roller 3 is controlled by a conveying drive component. The conveying drive component starts working when the first limiting roller 4 and the second limiting roller 5 are separated from the fabric. Under the conveying of the conveying roller 3, the flattened fabric is conveyed away, and the unflattened fabric is conveyed to the parallel linkage assembly and flattened. The specific conveying drive component can adopt existing technology, and this utility model will not provide further explanation.

[0035] In this embodiment, when the fabric is flattened, the first limiting roller 4 and the second limiting roller 5 first limit the fabric to prevent wrinkles from forming during the flattening process of the parallel linkage assembly. When the reciprocating drive is started, the parallel linkage assembly is controlled to move relative to each other on the worktable 1. When the parallel linkage assembly moves along the fabric conveying direction, the end of the parallel linkage assembly that abuts against the fabric is subjected to a downward force, ensuring that the parallel linkage assembly and the fabric are always in contact. This effectively removes wrinkles and uneven areas on the fabric surface, making the fabric smoother. During the reset process after the parallel linkage assembly moves to the end of its stroke, the first limiting roller 4 and the second limiting roller 5 can be driven to reciprocate up and down through the one-way transmission component. While releasing the limiting work on the fabric, the flattened fabric is conveyed away by the conveying roller 3, while the unflattened fabric is conveyed to the lower end of the parallel linkage assembly. When the parallel linkage assembly returns to the origin of its stroke, the first limiting roller 4 and the second limiting roller 5 resume limiting the fabric to wait for the next flattening operation, further improving the fabric flattening efficiency.

[0036] For further solutions to this utility model, please refer to [link / reference]. Figure 6 and Figure 7 The reciprocating drive includes a drive shaft 16 rotatably mounted on the support frame 2. One end of the drive shaft 16 is driven to rotate by a motor 15 mounted on the support frame 2, and a rotating plate 17 is provided on the other end. A protruding post 1701 is installed at the eccentric position of the rotating plate 17.

[0037] It also includes a push rod 18, on which a groove 1801 is formed for the insertion and sliding adaptation of the protrusion 1701, and one end of the push rod 18 away from the protrusion 1701 is connected to the deflector on the receiving frame 2.

[0038] The deflecting component includes a deflecting shaft 14 rotatably mounted on the receiving frame 2. A connecting plate 19 hinged to the push rod 18 is fixed between the two deflecting shafts 14. Deflecting rods 20 are symmetrically sleeved on the deflecting shafts 14. A limiting groove 2001 that is slidably connected to the parallel connecting rod assembly is provided along the length direction of the deflecting rod 20.

[0039] Specifically, after the fabric is laid flat on the worktable 1, the motor 15 is started. The output shaft of the motor 15 is fixed to the drive shaft 16, so that when the output shaft rotates, it can drive the drive shaft 16 to rotate synchronously, thereby realizing the rotation of the rotating plate 17. The protrusion 1701 on it makes a circular motion and always slides relative to each other in the slide groove 1801 during the motion. The protrusion 1701 squeezes the push rod 18. Due to the connection between the push rod 18 and the connecting plate 19, the push rod 18 can reciprocate under the squeezing of the protrusion 1701. The pushing of the push rod 18 causes the deflection shaft 14 and the deflection rod 20 to deflect, thereby providing drive for the parallel linkage assembly relative to the worktable 1.

[0040] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The parallel linkage assembly includes symmetrically arranged hinge plates 23, and a movable shaft 22 is rotatably arranged between the two hinge plates 23. The two ends of the movable shaft 22 pass through the hinge plates 23 and are inserted into the limiting groove 2001 and slide in cooperation with the limiting groove 2001.

[0041] It also includes an elastic pressing member arranged in parallel on the hinge plate 23, one end of which is hinged to the hinge plate 23.

[0042] The elastic extrusion member includes a plug-in sleeve plate 24, one end of which is hinged to the hinge plate 23, and the other end has an embedded groove. A pressure plate 25 is slidably disposed in the embedded groove, and the end of the pressure plate 25 away from the plug-in sleeve plate 24 can abut against the fabric.

[0043] It also includes a spring 26 disposed in the recessed groove, one end of the spring 26 abutting against the inner end of the recessed groove, and the other end abutting against the pressure plate 25.

[0044] In detail, when the fabric is flattened, the deflector rod 20 deflects relative to the fabric conveying direction. At this time, the movable shaft 22 in the limiting groove 2001 is squeezed, which causes the hinge plate 23 to change position and be subjected to an upward force. According to the parallelogram principle, the pressure plate 25 is subjected to a downward force to ensure that when the pressure plate 25 moves along the fabric conveying direction, the squeezing end formed by the pressure plate 25 and the fabric are always squeezed and in contact. This can effectively remove wrinkles and uneven areas on the fabric surface, making the fabric smoother.

[0045] It should be noted that the spring 26 is designed to accommodate the different thicknesses of different fabrics, in order to ensure that the pressing end of the pressure plate 25 is always in contact with the fabric when the fabric is flattened.

[0046] When the deflection rod 20 deflects in the opposite direction to the fabric conveying, the pressure plate 25 is subjected to an upward force. At this time, the pressure plate 25 separates from the fabric to facilitate the flattened fabric being conveyed away, while the unflattened fabric is conveyed to the lower end of the pressure plate 25 to wait for the next flattening operation.

[0047] Preferably, the hinge plate 23 has symmetrical and rotatably provided limit posts 2401 at both ends, and a support plate 28 is installed on the receiving frame 2. A slider 27 fixed to the limit post 2401 is slidably provided in the support plate 28. The slider 27 can ensure that the pressing end of the pressure plate 25 keeps in contact with the fabric when it moves along the fabric conveying direction.

[0048] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The unidirectional transmission component includes a transmission shaft 12 rotatably mounted on the receiving frame 2. The transmission shaft 12 is connected to the deflection shaft 14 via a ratchet assembly 13, and the transmission shaft 12 is connected to a connecting shaft 9 rotatably mounted on the receiving frame 2 via a belt 11. The rotation of the connecting shaft 9 can control the lifting component mounted on the receiving frame 2.

[0049] After the fabric is flattened, when the deflection rod 20 is reset, the rotation direction of the deflection shaft 14 changes. At this time, under the transmission of the ratchet assembly 13, the transmission shaft 12 can rotate. When the transmission shaft 12 rotates, under the transmission of the belt 11, the connecting shaft 9 rotates. When the connecting shaft 9 rotates, under the action of the two bevel gear sets 8, the two lifting components can be controlled to perform lifting and lowering work on the first limiting roller 4, so that the first limiting roller 4 and the second limiting roller 5 can be separated from the fabric at the same time, releasing the limitation on the fabric.

[0050] For further solutions to this utility model, please refer to [link / reference]. Figure 3 The lifting component includes an extrusion shaft 7 rotatably mounted on the receiving frame 2. The extrusion shaft 7 is connected to the connecting shaft 9 via a bevel gear set 8, and an inclined groove 701 is formed on the extrusion shaft 7.

[0051] It also includes a lifting cylinder 6 arranged axially along the extrusion shaft 7. A cylindrical cavity is formed in one end of the lifting cylinder 6. A ball bearing 601 adapted to the inclined groove 701 is movably arranged on the inner wall of the cylindrical cavity. The other end is rotatably connected to the first limiting roller 4.

[0052] Preferably, the receiving frame 2 is equipped with a guide rod 10 to limit the lifting of the lifting cylinder 6.

[0053] When the connecting shaft 9 rotates, the two extrusion shafts 7 can rotate simultaneously under the transmission of the bevel gear set 8. The inclined groove 701 on them extrudes the ball 601. Under the limit of the guide rod 10, the lifting cylinder 6 reciprocates along the axial direction of the extrusion shaft 7, so that the first limiting roller 4 is separated from the fabric. Under the action of the connecting rod 29, the first limiting roller 4 and the second limiting roller 5 can rise and fall synchronously to ensure the synchronous stability of the fabric limiting. After the first limiting roller 4 and the second limiting roller 5 are separated, the flattened fabric is conveyed away by the conveying roller 3, and the unflattened fabric is conveyed to the lower end of the pressure plate 25 to wait for the next flattening operation, which further improves the efficiency of fabric flattening.

[0054] Preferably, a support rod 21 is installed on the receiving frame 2, and a sleeve 30 is slidably arranged along the axial direction of the support rod 21. The end of the sleeve 30 away from the support rod 21 is rotatably connected to the second limiting roller 5 to support the second limiting roller 5.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
