Description

Technical Field

[0001] This utility model relates to the field of fabric processing applications, and in particular to a tension-adjustable pre-shrink roller assembly structure. Background Technology

[0002] In the pre-shrinking process of fabrics, the existing pre-shrinking machine usually uses a pre-shrinking roller group for fabric feeding. The pre-shrinking roller group usually adopts a fixed spacing design, which cannot adjust the tension according to the characteristics of different types of fabrics (such as elasticity, thickness, material, etc.). When processing highly elastic fabrics, the fixed tension can easily lead to excessive stretching of the fabric, affecting the dimensional stability of the subsequent setting process. When processing thick fabrics, if the tension is insufficient, the fabric will not adhere tightly to the rubber blanket, affecting the pre-shrinking quality, which in turn will have an adverse effect on the subsequent stretching, steaming and setting effect.

[0003] Common pre-shrinking machines typically employ multiple pre-shrinking rollers to support and conduct fabric, and are equipped with corresponding tension adjustment components. However, the adjustment of these pre-shrinking rollers often relies on independent adjustment of each roller, requiring individual adjustment of the outer diameter of each roller. This cumbersome process makes it difficult to ensure consistent adjustment amplitude across rollers, resulting in uneven tension across different areas of the fabric during operation and consequently affecting the pre-shrinking effect. Furthermore, existing tension-related structures are mostly fixed or have a single adjustment method, providing only basic tension and failing to allow for flexible adjustments based on the actual state of the fabric during operation. This does not meet the operational requirements of fabric processing applications. Therefore, a tension-adjustable pre-shrinking roller group structure is proposed. Utility Model Content

[0004] This utility model provides the following technical solution: a tension-adjustable pre-shrink roller assembly structure, comprising: A bracket, wherein a first mounting component is mounted on the upper outer side of the bracket, and a drive assembly is mounted on the back of the bracket, wherein the rotor of the drive assembly passes through the corresponding positions inside the bracket and the first mounting component; The transmission component is coaxially mounted on the outer end of the rotor of the drive assembly. The transmission component has a guide groove circumferentially opened inside, and a connector is inserted into the guide groove. A sliding component is inserted into the first mounting component at a position corresponding to the connector. The second mounting component is installed on the outer end of the sliding component. A pre-shrinking roller is connected to the outside of the second mounting component. A linear drive mechanism is installed at the middle position of the outside of the bracket. A guide component is connected to the output end of the linear drive mechanism. The meshing parts are hinged to the outer sides of the bracket. A swinging part is connected to the outside of the meshing parts. A tensioning roller is connected to the outer end of the swinging part. A mating part is installed on the top of each meshing part.

[0005] Preferably, the guide grooves are all inclined, the inner ends of the plugs are all connected to the surface of the corresponding side sliding parts, and the length of the plugs is greater than the thickness of the transmission parts, thereby improving the stability of the transmission.

[0006] Preferably, the bottom of both the drive assembly and the linear drive mechanism are connected to the outside of the bracket via feet, and reinforcing ribs are welded to the connection between the feet and the surface of the bracket. The guide is triangular in shape. The feet and reinforcing ribs improve the installation stability of the drive assembly and the linear drive mechanism.

[0007] Preferably, the bottom of each mating component engages with the meshing component via teeth, a cross arm is connected to the upper side of the support surface of the mating component, and rounded corners are provided at the front edge of each mating component to facilitate the movement of the mating component by the guide component.

[0008] Preferably, both ends of the cross arm are connected to side plates, and the inner side of each side plate is connected to an assembly. The assembly penetrates the corresponding position inside the mating part, and the added assembly improves the movement stability of the mating part.

[0009] Preferably, an elastic element is fitted on the outside of the assembly between the side plate and the mating part, and a through hole is opened inside the bracket at a position corresponding to the guide element, and the length and width of the through hole are larger than the guide element. The through hole avoids interference between the guide element and the bracket when the guide element moves.

[0010] In summary, compared with the prior art, this utility model provides a tension-adjustable pre-shrink roller assembly structure, which has the following beneficial effects: This tension-adjustable pre-shrink roller assembly structure, through a drive component that rotates the transmission component, can synchronously expand the sliding component and the second mounting component with the cooperation of the guide groove and the plug component. This allows for adjustment of the fabric tension through the expanded pre-shrink rollers, thereby achieving synchronous adjustment of the expansion diameter of multiple pre-shrink rollers. This avoids the uneven tension problem caused by adjusting each roller individually in traditional methods. Furthermore, the linear drive mechanism can drive the movement of the guide component, which in turn drives the rotation of the meshing and oscillating components through the mating component. This allows the tensioning roller to press down and tighten the fabric, supplementing the basic tension of the pre-shrink rollers and addressing local tension fluctuations during fabric movement. This effectively reduces fabric wrinkles and stretching deformation caused by unstable tension. Attached Figure Description

[0019] This utility model provides a technical solution: a tension-adjustable pre-shrink roller assembly structure, including a bracket 1, a first mounting component 2, a drive assembly 3, a transmission component 4, a guide groove 5, a connector 6, a sliding component 7, a second mounting component 8, a pre-shrink roller 9, a linear drive mechanism 10, a guide component 11, a meshing component 12, a swinging component 13, a tension roller 14, a cross arm 15, a side plate 16, an assembly component 17, a mating component 18, and an elastic component 19. Please see Figure 1 The bracket 1 is equipped with a first mounting part 2 on its upper outer side. The bracket 1 is located at the feed inlet of the pre-shrinking machine. The first mounting part 2 is a cross-shaped seat structure. The back of the bracket 1 is equipped with a drive assembly 3, which is a stepper motor. The rotor of the drive assembly 3 passes through the corresponding positions inside the bracket 1 and the first mounting part 2. Transmission component 4 is coaxially mounted on the outer end of the rotor of drive assembly 3. Transmission component 4 has a disc structure. Please refer to [link / reference]. Figure 3 The transmission component 4 has a guide groove 5 circumferentially oriented inside, and each guide groove 5 has a connector 6 inserted into it. The connector 6 is a rod. Please refer to [link / reference]. Figure 4 A sliding member 7 is inserted inside the first mounting member 2 at a position corresponding to the plug-in member 6. The sliding member 7 is a square insert plate. Please see Figure 2 The second mounting component 8 is installed on the outer end of the sliding component 7. The second mounting component 8 has a disc structure, and a pre-shrink roller 9 is connected to the outside of the second mounting component 8. Please refer to [link / reference]. Figure 5A linear drive mechanism 10 is installed at the outer middle position of the bracket 1. The linear drive mechanism 10 is an electric telescopic rod, and the output end of the linear drive mechanism 10 is connected to a guide member 11. Please see Figure 6 The meshing part 12 is hinged to the outer two sides of the bracket 1. The meshing part 12 is a gear. The outer side of the meshing part 12 is connected to the swinging part 13. The outer end of the swinging part 13 is connected to the tensioning roller 14. The top of the meshing part 12 is equipped with a mating part 18. All guide grooves 5 are inclined, and the inner ends of the plug-in parts 6 are connected to the surface of the corresponding side sliding parts 7. The length of the plug-in parts 6 is greater than the thickness of the transmission parts 4. The bottom of the drive assembly 3 and the linear drive mechanism 10 are connected to the outside of the bracket 1 through the legs. The connection between the legs and the surface of the bracket 1 is welded with reinforcing ribs. The guide parts 11 are triangular. Please see Figure 7 First, the fabric passes through the tension roller 14 on the right, then sequentially through the pre-shrink roller 9 in the upper right corner, the pre-shrink roller 9 in the lower right corner, the pre-shrink roller 9 in the lower left corner, the pre-shrink roller 9 in the upper left corner, and the tension roller 14 on the left. Then, the drive assembly 3 drives the transmission component 4 to rotate, thereby driving the sliding component 7 and the second mounting component 8 to expand synchronously under the cooperation of the guide groove 5 and the plug component 6. Thus, the tension on the fabric can be adjusted by the expanded pre-shrink roller 9, thereby realizing the synchronous adjustment of the expansion diameter of multiple sets of pre-shrink rollers 9, avoiding the problem of uneven tension caused by adjusting each roller individually in the traditional method. Furthermore, the linear drive mechanism 10 drives the movement of the guide component 11, thereby driving the rotation of the meshing component 12 and the swing component 13 through the mating component 18, so that the fabric can be pressed down and tensioned by the tension roller 14. This can not only supplement the basic tension of the pre-shrink roller 9, but also cope with the local tension fluctuations during the fabric operation, effectively reducing the problems of fabric wrinkles and stretching deformation caused by unstable tension. The bottom of each mating part 18 engages with the meshing part 12 through teeth. A cross arm 15 is connected to the upper side of the mating part 18 on the surface of the bracket 1. The front edge of the mating part 18 is rounded. Both ends of the cross arm 15 are connected to side plates 16. The inner side of each side plate 16 is connected to an accessory 17. The accessory 17 penetrates the corresponding position inside the mating part 18. An elastic element 19 is sleeved on the outside of the accessory 17 between the side plate 16 and the mating part 18. A through hole is opened inside the bracket 1 at the position corresponding to the guide 11, and the length and width of the through hole are larger than the guide 11.

[0020] This solution uses the drive component 3 to drive the rotation of the transmission component 4, which in turn drives the sliding component 7 and the second mounting component 8 to expand synchronously with the cooperation of the guide groove 5 and the plug component 6. This allows the tension on the fabric to be adjusted by the expanded pre-shrinking roller 9, thus achieving synchronous adjustment of the expansion diameter of multiple sets of pre-shrinking rollers 9. This avoids the problem of uneven tension caused by adjusting each roller individually in the traditional method. Furthermore, the linear drive mechanism 10 drives the movement of the guide component 11, which in turn drives the rotation of the meshing component 12 and the swing component 13 through the mating component 18. This allows the tensioning roller 14 to press down and tighten the fabric, which can both supplement the basic tension of the pre-shrinking roller 9 and cope with local tension fluctuations during fabric operation, effectively reducing the problems of fabric wrinkles and stretching deformation caused by unstable tension.
