Description

Technical Field

[0001] This utility model relates to the field of ribbon production equipment technology, and in particular to a ribbon weaving device. Background Technology

[0002] A webbing device is a specialized piece of equipment that produces ribbon-like fabrics through the interlacing or weaving of warp and weft yarns. The raw webbing produced is mostly cylindrical in shape, which is prone to tangling and takes up a lot of space when used directly. Therefore, it is necessary to compress the webbing into a flat shape after it is formed.

[0003] To reduce costs, existing webbing weaving equipment mostly uses manual pressing. After the webbing is formed, workers hold pressing wheels to squeeze the webbing. However, the pressing device on the existing webbing weaving equipment is difficult to adjust. Every time parameters are adjusted, the machine needs to be stopped and the position of the pressing device needs to be adjusted manually, which affects the capacity utilization rate. Utility Model Content

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides a webbing weaving device, including a machine body on which a weaving mechanism is provided. A support frame is also provided on the machine body on the other side opposite to the weaving mechanism. A pressing table is movably provided on the support frame, and multiple support columns for supporting the bottom of the pressing table are provided inside the support frame. Several rotating shafts are also rotatably provided inside the support frame. The rotating shafts are located above the pressing table. Connectors and pressing rollers are sequentially fixed on the side of the rotating shaft facing the pressing table, and the pressing rollers abut against the top of the pressing table.

[0007] In one embodiment, a base is fixed to the bottom of the support column. The base is movably mounted on the support frame. The support frame is rotatably mounted with a turntable. A traction member is fixed to the side of the turntable facing the base. The traction member extends in a ring shape from the inner circle of the turntable to the outer circle. The base has multiple longitudinally arranged toothed grooves that can be separably engaged with the traction member.

[0008] In one embodiment, a compression spring is fixed between the support column and the pressure table, with one end of the compression spring facing the pressure table abutting against the bottom of the pressure table.

[0009] In one embodiment, the other end of the compression spring is sleeved on the outside of the support column, and the end of the compression spring facing the pressure plate protrudes from the upper end of the support column.

[0026] Reference Figure 1 and Figure 2A webbing weaving device includes a machine body 1, on which a weaving mechanism 2 is mounted. A support frame 3 is also mounted on the machine body 1 on the opposite side of the weaving mechanism 2. A pressing table 4 is movably mounted on the support frame 3, and multiple support columns 5 for supporting the bottom of the pressing table 4 are disposed within the support frame 3. Several rotating shafts 6 are also rotatably mounted within the support frame 3, located above the pressing table 4. Connecting members 7 and pressure rollers 8 are sequentially fixed to the side of the rotating shafts 6 facing the pressing table 4. The pressure rollers 8 abut against the top of the pressing table 4. With this configuration, when it is necessary to compress and form the webbing, first... The longitudinal height of the pressing table 4 is adjusted according to the actual thickness of the webbing, so that the webbing can slide against the surface of the pressing table 4 after passing through the pressing hole of the machine body 1. Then, by controlling the rotation of the rotating shaft 6, the pressing roller 8 is rotated towards the pressing table 4, so that the webbing slides between the pressing roller 8 and the pressing table 4 and is tightly pressed by the pressing roller 8, finally forming a flat shape. By adjusting the height of the pressing roller 8 on the upper and lower sides of the webbing and the height of the pressing table 4 respectively, the pressure on the webbing is adjusted, so that the webbing weaving device in this utility model can quickly adjust the position of the pressing device according to the parameters of different webbings, thereby improving production efficiency.

[0027] In one specific embodiment, the support frame 3 is a frame structure and is fixed to the machine body 1 by bolts. The bottom of the support frame 3 is also provided with shock-absorbing pads. The pressing table 4 is made of aluminum alloy with anodized surface treatment. The top of the pressing table 4 is inlaid with anti-slip pads, the material of which includes, but is not limited to, polyurethane, to increase the friction between the webbing and the pressing table 4, so that the webbing can only slide along the arrangement direction of the pressing rollers 8, and to prevent the webbing from being offset to the left or right during the sliding process, resulting in uneven pressure.

[0028] In one specific embodiment, the rotating shaft 6 can be driven by a motor, including but not limited to a three-phase asynchronous motor, which can precisely control the rotation angle of the rotating shaft 6 to more accurately adjust the squeezing force of the pressure roller 8 on the webbing. In addition, the three-phase asynchronous motor has good shock resistance, which can ensure that the pressure roller 8 will not flip on its own due to pressure during the pressing process and affect the pressing effect. If it is necessary to reduce costs, the rotating shaft 6 can be rotated by manual flipping, which is less accurate than motor control. After adjusting the position of the pressure roller 8, the rotating shaft 6 is locked and fixed by screwing the bolt from the support frame 3 into the rotating shaft 6.

[0029] In one specific embodiment, the pressing table 4 can be tilted so that the distance between the pressure rollers 8 on the table surface gradually decreases in the direction of the webbing's sliding. Therefore, the squeezing force of the pressure rollers 8 on the webbing gradually increases, forcing the webbing fibers to fully extend and shape. Furthermore, the progressive pressing can effectively reduce the rebound deformation of the webbing after pressing, which is better than multiple pressure rollers 8 squeezing the webbing with the same force. At the same time, after the webbing is continuously squeezed through multiple stages, not only can its internal stress distribution be made more uniform to avoid local stress concentration that could lead to webbing breakage or deformation, but it can also reduce the lateral pulling on the webbing during the pressing process, avoiding fiber breakage. Therefore, when the height of different support columns 5 is adjusted to make the pressing table 4 tilted, the webbing squeezed by the pressure rollers 8 can have better performance.

[0030] In one specific embodiment, the support frame 3 forms a linkage mechanism with the rotating shaft 6 through multiple support columns 5, forming a stable pressing working plane. The sliding contact design between the pressing roller 8 and the pressing table 4 ensures uniform pressure distribution and reduces friction loss, so that the webbing can maintain flatness when sliding continuously. Furthermore, the synergistic effect of the pressing table 4 and the pressing roller 8 can better eliminate uneven stress inside the webbing, ensuring that the finished webbing meets the standard thickness and flatness requirements.

[0031] In one specific embodiment, the weaving mechanism 2 includes a frame frame with a power transmission shaft running through the middle. The right side of the frame is the drive system for weaving the webbing, while the left side integrates the control module and pressure display device. The bottom of the frame is reinforced by cross support beams. When the webbing is completed in the weaving mechanism 2, it is transported to the pressing table 4 through the power transmission shaft for the pressing process.

[0032] Reference Figure 1 and Figure 4 A base 9 is fixedly mounted at the bottom of the support column 5. The base 9 is movably mounted on the support frame 3. A turntable 10 is rotatably mounted on the support frame 3. A traction member 11 is fixedly mounted on the side of the turntable 10 facing the base 9. The traction member 11 extends in a ring shape from the inner circle of the turntable 10 to the outer circle. The base 9 has multiple longitudinally arranged toothed grooves 12. The toothed grooves 12 can be separably engaged with the traction member 11. With this configuration, the turntable 10 drives the traction member 11 to rotate. During the rotation of the turntable 10, the part of the traction member 11 located in the inner circle of the turntable 10 and the part located in the outer circle of the turntable 10 alternately engage with the toothed grooves 12. During the alternating engagement, as the curved side of the traction member 11 abuts against the inner groove surface of the toothed groove 12 one by one, the base 9 produces linear motion due to the push of the toothed contact force. Therefore, when the turntable 10 rotates in the direction where the curvature of the traction member 11 expands, the base 9 rises, and vice versa.

[0033] In one specific embodiment, the meshing process between the traction member 11 and the toothed groove 12 does not involve linear sliding, resulting in a constant transmission ratio and high displacement accuracy. Furthermore, by increasing the width of the traction member 11, the contact area between the traction member 11 and the toothed groove 12 can be increased, thereby enhancing the load-bearing capacity of the traction member 11. This allows it to withstand greater impact loads when meshing with the toothed groove 12 of the base 9. This not only ensures stable lifting and lowering of the base 9 but also prevents the base 9 from falling due to misalignment of the toothed groove 12 and the traction member 11 caused by the weight of the base 9 during meshing. Simultaneously, the movement direction of the base 9 can be quickly switched by rotating the turntable 10, providing a fast response and facilitating rapid adjustment of the height of the support column 5 by the operator. Finally, the structure in which the base 9 is lifted and lowered by the meshing of the traction member 11 and the toothed groove 12 is not only easy to lubricate and inspect but also allows for individual replacement of worn components, effectively reducing production costs.

[0034] In one specific embodiment, the operator can adjust the height of each support column 5 to adjust the tilt angle of the pressing table 4, and at the same time adjust the distance between the pressing table 4 and the pressing roller 8, so that the squeezing force of the pressing roller 8 on the webbing can be adjusted accordingly. Therefore, during the pressing process, if it is necessary to adjust the squeezing force of the pressing roller 8 on the webbing according to the thickness of different webbing styles, or if it is necessary to tilt the pressing table 4 to perform progressive squeezing on the webbing, the operation can be completed simply by controlling the lifting and lowering of the support column 5 by rotating the turntable 10, which is convenient and quick. As for the method of rotating the shaft 6 to drive the pressing roller 8 to flip, it can be used when the thickness of the webbing changes significantly or the webbing style is more complex and requires repeated progressive squeezing.

[0035] Reference Figure 1 A compression spring 13 is fixed between the support column 5 and the pressure table 4. The end of the compression spring 13 facing the pressure table 4 abuts against the bottom of the pressure table 4. With this arrangement, the compression spring 13 can adaptively compress under the pressure of the pressure roller 8 to adjust the height of the pressure table 4, further ensuring the quality and stability of the webbing. Firstly, the webbing material may have thickness differences or surface undulations due to the weaving pattern, and rigid compression will cause uneven pressure or even damage the material. However, the adaptive adjustment of the compression spring 13 can ensure that the pressure is evenly distributed. First, the pressing pressure of the roller 8 is applied to the webbing relatively evenly. Second, the self-adjusting compression of the compression spring 13 can compensate for wear gaps. After long-term use, the table surface of the pressing table 4 may develop gaps due to wear, resulting in loose or ineffective pressing. At this time, the compression spring 13 can further ensure that the pressing roller 8 can press the webbing. Third, if there are foreign objects stuck in the webbing, rigid pressing can easily lead to the webbing breaking or the pressing roller 8 being damaged. The presence of the compression spring 13 can prevent the pressing roller 8 from directly over-pressing, thus improving the safety of the pressing roller 8 and the webbing.

[0036] Reference Figure 1The other end of the compression spring 13 is sleeved on the outside of the support column 5, and the end of the compression spring 13 facing the pressure table 4 protrudes from the upper end of the support column 5. With this arrangement, the support column 5 acts as a rigid support structure, which can guide the compression spring 13 to compress or extend axially, so as to avoid the compression spring 13 from bending or twisting non-axially due to lateral force during compression. At the same time, the support column 5 can also limit the elastic deformation amplitude of the compression spring 13. When the pressure table 4 is pressed down to abut against the support column 5, the compression spring 13 can no longer perform elastic deformation, thus preventing the compression spring 13 from being damaged due to excessive compression.

[0037] Reference Figure 1 , Figure 3 and Figure 5 The support frame 3 has an opening 14, on which a positioning element 15 is slidably mounted. The turntable 10 has multiple positioning grooves 16 on the side near the positioning element 15, and the positioning grooves 16 are arranged in a ring. One end of the positioning element 15 protrudes from the opening 14, and the other end is detachably embedded in the positioning groove 16. With this configuration, after the height of the support column 5 is adjusted by rotating the turntable 10, the positioning element 15 is inserted into the opening 14 and embedded in the positioning groove 16 at the end facing the turntable 10, so that the positioning element 15 plays a mechanical fixing role, further preventing the turntable 10 from rotating on its own due to the vibration of the machine body 1 during the pressing process.

[0038] Reference Figure 1 , Figure 3 and Figure 5 A rotating component 17 is fixed on the side of the turntable 10 away from the base 9. The end of the rotating component 17 away from the turntable 10 is rotatably inserted through the support frame 3 and is fixed with a control handle 18. With this arrangement, the control handle 18 is located on the outside of the support frame 3, which makes it convenient for the staff to directly control the rotation of the turntable 10 through the control handle 18.

[0039] In one specific embodiment, a limiting member is fixed at the bottom of the pressure table 4. The limiting member is annularly wrapped around the outside of the compression spring 13, and a groove for the compression spring 13 to be embedded is formed between the limiting member and the pressure table 4. With this arrangement, the limiting member can further restrict the radial translation of the compression spring 13. The limiting member presses against and restricts the outside of the compression spring 13, avoiding the compression spring 13 from shifting due to lateral force during compression, which would cause uneven elastic force of the compression spring 13 on the pressure table 4.
