tenter track

Abstract

This utility model discloses a fabric feeding track for a tenter frame, relating to the technical field of tenter frame machines. It includes a frame-shaped track with a slider slidably connected inside. A connecting plate is fixedly connected to the top of the slider, and a fabric clamp is fixedly connected to one end of the connecting plate. A locking assembly is provided inside the slider, and a housing is fixedly installed on one side of the slider via the locking assembly. Locking blocks are fixedly connected to both sides of the top of the housing. This utility model, through its positioning assembly, can self-lock after transmission stops, effectively positioning the fabric clamp and the conveyed fabric. By activating the drive cylinder, the moving plate moves horizontally, simultaneously causing the limiting block to slide within the limiting groove, causing both moving plates to move outwards simultaneously. This, in turn, causes the connecting rod and the abutment plate to move outwards, ultimately causing the abutment plate to abut against the inner wall of the frame-shaped track, locking the positions of the slider and the fabric clamp, ensuring the fabric remains stable after transmission stops.

Description

Technical Field

[0001] This utility model relates to the field of tenter frame technology, specifically to the fabric feeding track of a tenter frame. Background Technology

[0002] A tenter frame is a piece of equipment used for the subsequent finishing of textiles. It stretches the fabric laterally to the target width using needle plates or clamps, adjusts the fabric width and warp and weft yarn configuration, and rearranges the fiber molecular structure in a high-temperature environment of 180-220℃ (the temperature can be adjusted according to the fabric material), eliminating internal fiber stress. After high-temperature setting, the fabric is rapidly cooled to fix its shape and ensure that it is not easily deformed or shrunken during subsequent use.

[0003] Common fabric feeding tracks use a clamping method to transport fabric. This involves holding the fabric in a clamp on both sides, and the clamp rotates along the track. There are many types of tracks, but a common type is a frame track. Pulleys are installed at the bottom of the clamp, and the fabric is transported by sliding the pulleys on the frame track. However, the fabric feeding track cannot self-lock after the transmission stops. Because the pulleys have a certain degree of reversibility, the clamp is prone to displacement after the transmission stops, making it impossible to maintain stability. Therefore, we propose a fabric feeding track for a tenter frame to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a fabric feeding track for a tenter frame, which is equipped with a positioning component that can self-lock after the transmission stops, effectively positioning the fabric clamp and the conveyed fabric. At the same time, the positioning component can be installed by snap-fit, which is convenient for personnel to maintain and replace, thereby facilitating the operation of the user.

[0005] To address the aforementioned technical problems, this application provides a fabric feeding track for a tenter frame, comprising a frame-shaped track. A slider is slidably connected inside the frame-shaped track. A connecting plate is fixedly connected to the top of the slider. A fabric clamp is fixedly connected to one end of the connecting plate. A snap-fit ​​assembly is provided inside the slider. A housing is fixedly mounted on one side of the slider via the snap-fit ​​assembly. Locking blocks are fixedly connected to both sides of the top of the housing. Slots are provided inside the locking blocks. A positioning assembly is provided inside the housing. Several rollers are rotatably connected to the outside of the slider, and the slider is slidably connected to the frame-shaped track via the rollers.

[0006] The present invention is further configured such that the snap-fit ​​assembly includes a groove, a sliding plate and a spring, the groove is formed inside the slider, there are two sliding plates, the outer side of the sliding plate is slidably connected to the inner wall of the groove, and the two ends of the spring are respectively fixedly connected to the two sliding plates.

[0007] The present invention is further configured such that the snap-fit ​​assembly includes a plug rod and a switch plate, one end of the plug rod is fixedly connected to the outside of the sliding plate, and the bottom end of the switch plate is fixedly connected to the outside of the sliding plate.

[0008] The present invention is further configured such that the card block is located inside the groove, and the slot matches the model of the insertion rod.

[0009] The present invention is further configured such that the positioning component includes a guide rail, a guide block, and a movable plate. The outer side of the guide rail is fixedly connected to the inner wall of the housing. There are two guide blocks, the inner wall of which is slidably connected to the outer side of the guide rail. The outer side of the movable plate is fixedly connected to the outer side of the guide block.

[0010] The present invention is further configured such that the positioning assembly includes a connecting rod, an abutment plate, and a driving cylinder. One end of the connecting rod is fixedly connected to the outside of the movable plate, the outside of the abutment plate is fixedly connected to one end of the connecting rod, and one end of the driving cylinder is fixedly connected to the outside of the housing. The driving cylinder is located inside the slider.

[0011] The present invention is further configured such that the positioning component includes a movable plate, a limiting block, and a limiting groove. The outer side of the movable plate is fixedly connected to the output shaft of the driving cylinder. There are two limiting blocks, which are fixedly connected to both sides of the movable plate. The limiting groove is opened inside the movable plate. The shape of the limiting groove is a trapezoid with a wider outer side and a narrower inner side. The models of the limiting blocks and the limiting grooves are consistent.

[0012] This utility model has at least the following beneficial effects:

[0013] I. This utility model, through its positioning component, can self-lock after the transmission stops, effectively positioning the fabric clamp and the conveyed fabric. By starting the drive cylinder, the moving plate is pushed to move horizontally, while the limiting block slides in the limiting groove, causing the two moving plates to move outwards simultaneously. This, in turn, causes the connecting rod and the abutment plate to move outwards, ultimately causing the abutment plate to abut against the inner wall of the frame track, locking the position of the slider and the fabric clamp, and keeping the fabric stable after the transmission stops.

[0014] II. This utility model, through the set snap-fit ​​component, allows for the installation and disassembly of the housing by snap-fit, facilitating the maintenance and replacement of the positioning component. Simultaneously, pressing the two switch plates causes the two sliding plates to move closer together, compressing the spring and moving the insertion rod, increasing the distance between the insertion rod and the locking block. Once the insertion rod is completely disengaged from the slot, the restriction on the housing is released, and the housing can then be pulled out for maintenance or replacement of the positioning component.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-6 As shown, this utility model provides a technical solution: a fabric feeding track for a tenter frame includes a frame track 1, a slider 2 is slidably connected inside the frame track 1, a connecting plate 3 is fixedly connected to the top of the slider 2, a fabric clip 4 is fixedly connected to one end of the connecting plate 3, a snap-fit ​​assembly 5 is provided inside the slider 2, a housing 6 is fixedly installed on one side of the slider 2 through the snap-fit ​​assembly 5, a snap-fit ​​block 7 is fixedly connected to both sides of the top of the housing 6, a slot 8 is opened inside the snap-fit ​​block 7, a positioning assembly 9 is provided inside the housing 6, and several rollers 10 are rotatably connected to the outside of the slider 2, and the slider 2 is slidably connected to the frame track 1 through the rollers 10;

[0024] The fabric is clamped on both sides of the fabric clamp 4. Then the slider 2 slides in the frame track 1 via the roller 10, which drives the fabric clamp 4 to move, and in turn drives the fabric to move to convey the fabric. When the transmission stops, the positioning component 9 can self-lock after the transmission stops, effectively positioning the fabric clamp 4 and the conveyed fabric. The set snap-fit ​​component 5 can be used to install and remove the housing 6 by snap-fit, which is convenient for personnel to maintain and replace the positioning component 9.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the snap-fit ​​assembly 5 includes a groove 501, a sliding plate 502, a spring 503, a plug rod 504, and a switch plate 505. The groove 501 is formed inside the slider 2. There are two sliding plates 502. The outer side of the sliding plate 502 is slidably connected to the inner wall of the groove 501. The two ends of the spring 503 are fixedly connected to the two sliding plates 502 respectively. One end of the plug rod 504 is fixedly connected to the outer side of the sliding plate 502. The bottom end of the switch plate 505 is fixedly connected to the outer side of the sliding plate 502. The snap-fit ​​block 7 is located inside the groove 501. The slot 8 matches the model of the plug rod 504.

[0026] Pressing both switch plates 505 simultaneously causes the two sliding plates 502 to move closer together, compressing the spring 503 and moving the insertion rod 504, increasing the distance between the insertion rod 504 and the locking block 7. Once the insertion rod 504 is completely disengaged from the slot 8, the restriction on the housing 6 can be released, and the housing 6 can then be pulled out for maintenance or replacement of the positioning component 9.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the positioning component 9 includes a guide rail 901, a guide block 902, a movable plate 903, a connecting rod 904, an abutment plate 905, a drive cylinder 906, a moving plate 907, a limiting block 908, and a limiting groove 909. The outer side of the guide rail 901 is fixedly connected to the inner wall of the housing 6. There are two guide blocks 902, and the inner wall of the guide block 902 is slidably connected to the outer side of the guide rail 901. The outer side of the movable plate 903 is fixedly connected to the outer side of the guide block 902. One end of the connecting rod 904 is fixedly connected to the outer side of the movable plate 903. The abutment plate 906... The outer side of 5 is fixedly connected to one end of the connecting rod 904, one end of the driving cylinder 906 is fixedly connected to the outer side of the housing 6, the driving cylinder 906 is located inside the slider 2, the outer side of the moving plate 907 is fixedly connected to the output shaft of the driving cylinder 906, there are two limiting blocks 908, the limiting blocks 908 are fixedly connected to both sides of the moving plate 907, the limiting groove 909 is opened inside the movable plate 903, the shape of the limiting groove 909 is a trapezoid with a wider outer side and a narrower inner side, and the models of the limiting blocks 908 and the limiting groove 909 match;

[0028] By starting the drive cylinder 906, the moving plate 907 is pushed to move horizontally, and at the same time the limiting block 908 slides in the limiting groove 909, causing the two moving plates 903 to move outward at the same time. This, in turn, causes the connecting rod 904 and the abutment plate 905 to move outward, and finally the abutment plate 905 abuts against the inner wall of the frame track 1, locking the position of the slider 2 and the fabric clamp 4, so that the fabric remains stable after the transmission stops.

[0029] Working principle: In use, the fabric is clamped on both sides of the fabric clamp 4. Then, the slider 2 slides in the frame track 1 via the roller 10, which drives the fabric clamp 4 to move, and in turn drives the fabric to move to convey the fabric. When the transmission stops, the drive cylinder 906 is started to drive the moving plate 907 to move horizontally. At the same time, the limiting block 908 slides in the limiting groove 909, so that the two movable plates 903 move outward at the same time. This drives the connecting rod 904 and the abutment plate 905 to move outward. Finally, the abutment plate 905 abuts against the inner wall of the frame track 1, locking the position of the slider 2 and the fabric clamp 4, so that the fabric remains stable after the transmission stops. Conversely, the drive cylinder 906 drives the moving plate 907 to move in the opposite direction, which can release the locking of the slider 2 and the fabric clamp 4. When the movable plate 903 moves, it can drive the guide block 902 to slide on the guide rail 901, thereby increasing stability.

[0030] When it is necessary to maintain or replace the drive cylinder 906, the two switch plates 505 can be pressed at the same time to move the two sliding plates 502 closer together, so that the spring 503 is compressed and the insertion rod 504 moves, increasing the distance between the insertion rod 504 and the locking block 7. When the insertion rod 504 is completely disengaged from the inside of the slot 8, the restriction on the housing 6 can be released, and then the housing 6 can be pulled out to maintain or replace the drive cylinder 906.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
