Description

Technical Field

[0001] The utility model relates to the technical field of cord fabric production, in particular to a device for automatically removing excess thread of a large creel bobbin of a cord fabric loom. Background Art

[0002] At present, in the production and processing of cord fabric, the production mode of air jet loom with large creel is generally adopted. Its main weaving process is: the warp let-off motor of the loom drives the roller to rotate, so that the warp yarn naturally withdraws from the bobbin of the large creel, enters the warp let-off mechanism after being sorted by the collection creel, passes through the roller set on the warp let-off mechanism, and then is sent to the take-up roller through other mechanisms on the loom. At the same time, compressed air pulls the weft yarn, and the weft yarn and the warp yarn intersect horizontally and vertically to weave the cord fabric. The large winding roller rotates at a uniform speed, pulling the cord fabric, and thus winding it into a cloth roll.

[0003] The above large creel, warp let-off frame and loom are arranged in sequence, and several bobbins are arranged on both sides of the large creel. A large creel can be equipped with about 2,000 bobbins. Several bobbins are arranged in a rectangular array, with multiple layers and multiple bobbins on each layer. Yarn is wound on the bobbin, and each bobbin can rotate on the large creel to release and withdraw the yarn.

[0004] In the process of weaving the cord fabric, after weaving each frame of fabric, some residual threads will remain on the bobbins on the large creel, which is called waste thread. In order to ensure that the bobbins can be used in a turnover manner and meet normal production, the residual threads on the bobbins need to be removed.

[0005] The specific processing process is as follows: every day is divided into morning shift, mid-shift and night shift, and each shift requires 3 workers to operate. They need to remove the 2,000 bobbins wrapped with residual silk threads on the large yarn rack one by one, fill the special net car and transport it to the wire drawing machine, where 2 wire drawing workers use the wire drawing machine to pull the residual silk threads away. Since the number of bobbins that the wire drawing machine can process at one time is limited, it is necessary to repeatedly replace the bobbins and start and stop the wire drawing machine at least 30 times, which takes nearly 3 hours to pull away the residual silk threads of thousands of bobbins on a loom. After the residual silk threads are processed, the empty bobbins are collected by the net car and transported to the specified area.

[0006] The entire processing process above requires transferring the bobbin with waste silk to the wire drawing machine, repeatedly removing it, and then transferring the empty bobbin to the specified area. The operation is inconvenient and cumbersome, time-consuming and labor-intensive, with low efficiency and certain operational safety hazards. It is necessary to further optimize the operation process of the remaining silk on the bobbin to improve production efficiency and the economic benefits of the enterprise. Summary of the invention

[0007] In order to solve the problems that the conventional method of removing the remaining silk threads by a wire drawing machine is cumbersome to operate, labor-intensive and has low removal efficiency, the utility model provides a device for automatically removing the remaining silk threads of a large creel bobbin of a tire cord fabric loom. The bobbins on the large creel are not removed first, and the waste silk threads on a plurality of bobbins are introduced into the device. The waste silk threads are automatically pulled out from the bobbins through the squeezing movement between the rollers, and then the empty bobbins are transported to a specified area.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A device for automatically removing excess thread of a large creel bobbin of a cord fabric loom is arranged between a let-off frame and the large creel, and comprises a movable frame, an active roller, a driven roller, a squeezing roller, a movable cylinder, a wire dividing plate, a reduction motor and an electrical control box;

[0010] The active roller, the driven roller and the squeezing roller are rotatably arranged on the frame.

[0011] The squeezing roller can be slidably arranged on the frame, and the position of the squeezing roller is adjustable. The movable cylinders are arranged on both sides of the frame. The piston rod of each movable cylinder extends out of the end connected to the squeezing roller, and can drive the squeezing roller to move and adjust the position.

[0012] The frame is also provided with the wire dividing plate for separating the combed silk threads to avoid confusion among the waste silk threads. The reduction motor and the electrical control box are arranged at one end of the frame. The output shaft of the reduction motor is connected to the active roller roller to facilitate driving the three roller rollers to rotate. The electrical control box is connected to the reduction motor and the mobile cylinder to facilitate the control of the operation of the parts.

[0013] Furthermore, the mobile rack includes wall panels, connecting struts and moving wheels. The number of the wall panels is two and they are arranged at intervals. A plurality of the connecting struts are provided between the two wall panels to connect them, thereby forming the main structure of the mobile rack. The moving wheels are provided at the bottom of each wall panel to realize the movable function of the mobile rack.

[0014] Furthermore, both ends of the active roller and the driven roller are provided with bearing seats for rotationally connecting with the wallboard;

[0015] A slide groove is provided on the wall panel, and sliding bearing seats are provided at both ends of the extrusion roller. The sliding bearing seats are slidably arranged in the slide groove, which facilitates the adjustment of the position of the extrusion roller. The piston rod of the moving cylinder extends into the slide groove and connects to the sliding bearing seat, which can facilitate driving the extrusion roller to move.

[0016] Furthermore, the active roller, the squeezing roller and the driven roller are arranged in an isosceles right triangle;

[0017] The two ends of the active roller are provided with active gears, the two ends of the extrusion roller are provided with extrusion gears, and the two ends of the driven roller are provided with driven gears.

[0018] Furthermore, the wire dividing plate is arranged between two wall panels, and the wire dividing plate includes an installation section and a wire dividing section that are bent and integrally formed. The installation section and the wire dividing section are distributed up and down, and the wire dividing plate is a plate body with a comb tooth structure, which is convenient for evenly separating the waste wires; the reduction motor and the moving cylinder are both arranged on one of the wall panels.

[0019] Through the above technical solution, the beneficial effects of the utility model are:

[0020] The utility model has a reasonable structural design. The waste silk threads on the bobbins on the large creel can be introduced into the device together. The waste silk threads are first separated and combed by the wire dividing plate, and then evenly introduced and wound between the three rollers. Through the synchronous operation of the active roller, the driven roller and the squeezing roller, the waste silk threads can be tightly squeezed, so that the waste silk threads can be automatically pulled out from the bobbins. In this way, there is no need to remove the bobbins one by one and transport them to the wire drawing machine for the tedious operation of removing the waste silk threads. The device is easy to operate, can save time and labor, and improve the removal efficiency, thereby achieving the effect of improving production efficiency and enterprise economic benefits.

DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0028] like Figure 1~Figure 5 As shown, a device for automatically removing excess thread of a large creel bobbin of a cord fabric loom is arranged between a let-off frame and a large creel, and includes a movable frame 1, an active roller 2, a driven roller 3, a squeezing roller 4, a movable cylinder 5, a wire dividing plate 6, a reduction motor 7 and an electrical control box 8, as shown in FIG. Figure 1 shown.

[0029] The mobile frame 1 is the basis of the whole device, and the mobile frame 1 has the characteristic of being movable. The mobile frame 1 includes a wall panel 101, a connecting strut 102 and a moving wheel 103. The wall panel 101 is a rectangular plate body with a chamfered corner. The wall panel 101 is made of a 20 mm thick steel plate, and the number of the wall panels 101 is two arranged at intervals. A plurality of connecting struts 102 are arranged between the two wall panels 101 to connect and fix the two wall panels 101 together. The connecting struts 102 are made of 40*40 mm seamless square steel. A moving wheel 103 is arranged at the bottom of each wall panel 101 to realize the mobility of the mobile frame 1.

[0030] A driving roller 2, a driven roller 3 and a squeezing roller 4 are rotatably arranged on the frame. The driving roller 2, the driven roller 3 and the squeezing roller 4 are all made of seamless steel rollers, and the surfaces of the three rollers are smooth chrome-plated. Figure 2 shown.

[0031] When the active roller 2 and the driven roller 3 are installed, bearing seats are provided at both ends of the active roller 2 and the driven roller 3 to be rotatably connected to the wall panel 101. Here, the installation positions of the active roller 2 and the driven roller 3 are fixed.

[0032] It should be noted that the installation position of the squeezing roller 4 is adjustable, that is, the squeezing roller 4 can be slidably arranged on the frame. Specifically, a slide groove 9 is provided on the wall panel 101, and the slide groove 9 forms a certain angle with the horizontal plane. Sliding bearing seats 10 are provided at both ends of the squeezing roller 4, and the sliding bearing seats 10 are slidably arranged in the slide groove 9, so that the squeezing roller 4 can move relative to the movable frame 1, so as to be close to the active roller 2 and the squeezing roller 4 at the same time, or to be away from the active roller 2 and the squeezing roller 4 at the same time.

[0033] In order to drive the squeezing roller 4 to slide, a moving cylinder 5 is provided on both sides of the frame. The moving cylinder 5 is arranged at the chamfer of the wall panel 101. The moving cylinder 5 is connected to compressed air to provide an air source for the operation of the moving cylinder 5. The piston rod of each moving cylinder 5 extends out and connects to the end of the squeezing roller 4, that is, the piston rod of the moving cylinder 5 extends into the slide groove 9 and connects to the sliding bearing seat 10. The squeezing roller 4 can be driven to move along the slide groove 9 by the synchronous operation of the two moving cylinders 5.

[0034] The active roller 2, the squeezing roller 4 and the driven roller 3 are arranged in parallel, and when the rollers work together, the active roller 2, the squeezing roller 4 and the driven roller 3 are in contact with each other in sequence. At this time, the active roller 2, the squeezing roller 4 and the driven roller 3 are arranged in an isosceles right triangle, and the waste silk thread on the bobbin is wound around the active roller 2, the squeezing roller 4 and the driven roller 3 in sequence and is squeezed.

[0035] In order to realize the driving of the active roller 2, a reduction motor 7 and an electrical control box 8 are arranged at one end of the frame, that is, the reduction motor 7 and the mobile cylinder 5 are both arranged on a wall panel 101, and the reduction motor 7 is composed of a motor and a reducer. The output shaft of the reduction motor 7 is connected to the active roller 2, thereby driving the active roller 2 to operate. The electrical control box 8 is connected to the reduction motor 7 and the mobile cylinder 5, and can control the operation of the reduction motor 7. At the same time, the electrical control box 8 is provided with a manual reversing valve, which can control the extension and retraction of the mobile cylinder 5.

[0036] On the basis of the reduction motor 7 driving the active roller 2 to run, in order to realize the synchronous operation of the three rollers, the ends of the active roller 2, the squeezing roller 4 and the driven roller 3 are meshed and driven in sequence, such as Figure 4 Specifically, driving gears 11 are provided at both ends of the driving roller 2, extrusion gears 12 are provided at both ends of the extrusion roller 4, and driven gears 13 are provided at both ends of the driven roller 3. The driving gear 11, the extrusion gear 12 and the driven gear 13 are meshed in sequence to achieve the effect of synchronous transmission operation.

[0037] Since the waste silk threads on several bobbins are introduced into the device and pulled by the device to remove the waste silk threads, in order to avoid the waste silk threads from being mixed together, a wire dividing plate 6 for separating the combed silk threads is also provided on the frame. Figure 3 The wire dividing plate 6 is arranged between two wall panels 101, and includes a mounting section 61 and a wire dividing section 62 which are bent and integrally formed. The mounting section 61 and the wire dividing section 62 are distributed up and down, and the mounting section 61 is bolted to a connecting strut 102. The wire dividing plate 6 is a plate body with a comb-tooth structure, which can evenly and orderly separate the waste wires to avoid entanglement between the waste wires.

[0038] The principle of the utility model is as follows: after weaving is finished, the device is moved between the let-off frame and the large creel, the moving cylinder 5 is operated to make the squeezing roller 4 away from the active roller 2 and the driven roller 3, the ends of the waste silk threads on the bobbins on the large creel are pulled out in a concentrated manner, and after being evenly separated by the wire dividing plate 6, the waste silk threads are introduced from below the active roller 2, wound upwardly on the squeezing roller 4, bypassed half a circle of the squeezing roller 4, and then downwardly wound around the inner side of the driven roller 3, and then the waste silk threads are pulled out, and at this time the ends of the waste silk threads face the bottom of the moving frame 1.

[0039] The moving cylinder 5 is operated to make the squeezing roller 4 approach the active roller 2 and the driven roller 3 until the squeezing roller 4 forms a tight squeeze with the active roller 2 and the driven roller 3. At this time, the active gear 11, the squeezing gear 12 and the driven gear 13 at the ends of the three rollers enter a meshing state. Figure 5 shown.

[0040] Start the reduction motor 7, and then under the meshing action of the gears, the three rollers run synchronously, relying on the tight squeezing between the squeezing roller 4 and the active roller 2 and the driven roller 3 to automatically pull out the waste silk thread, and the pulled waste silk thread is accumulated on the ground under the mobile frame 1, and can be collected uniformly later. After the waste silk thread is removed, the rack worker only needs to remove the empty bobbin from the large creel, fill the net car and transport it to the specified area. The above entire waste silk thread removal process only takes about 60 minutes to complete the automatic removal and collection of the remaining thread of the bobbin of the large creel of a loom.

[0041] In order to optimize the product structure and ensure the stability of the device during operation, telescopic legs are also provided on the mobile frame 1. There are two telescopic legs, each close to the two wall panels 101, and each telescopic leg is installed on the connecting support rod 102. The telescopic legs include a telescopic rod 14 and a screw rod 15 provided at one end of the telescopic rod 14. The length of the telescopic rod 14 is adjustable, and the locking and unlocking of the telescopic rod 14 are achieved by a locking bolt 16. The screw rod 15 is arranged vertically, and a stabilizing block 17 is provided below the screw rod 15. The screw rod 15 can drive the stabilizing block 17 to move up and down. When the stabilizing block 17 is pressed against the ground, the mobile frame 1 can be prevented from moving, thereby improving the stability of the device.
