Description

Technical Field

[0001] This invention relates to the field of spinning auxiliary equipment technology, specifically a high-efficiency combing roller wrapping machine. Background Technology

[0002] The combing roller is an important component in spinning equipment. It is mainly installed in the combing chamber and is used to grab and comb the fed noodle fibers. The centrifugal force generated by its high-speed rotation can throw out the grabbed fibers. The existing combing roller mainly consists of a roller body with threaded grooves on the outer wall and a serrated strip with serrations wound in the threaded grooves of the roller body. The process of winding the serrated strip in the threaded grooves of the roller body is called the combing roller wrapping process, and the equipment used to complete the combing roller wrapping process is called a combing roller wrapping machine.

[0003] Currently, a common type of combing roller wrapping machine on the market is the FU204 model. This machine mainly includes: a machine base, a three-jaw chuck mounted on the machine base for clamping and positioning the combing roller body, and an extrusion wheel for clamping the toothed strip into the threaded groove on the roller body. The extrusion wheel has grooves on its surface. During the combing roller wrapping process, the toothed portion of the toothed strip is embedded in the threaded groove on the outside of the combing roller body, and the toothed portion of the strip is confined within the grooves on the extrusion wheel surface. Inside the groove; When the combing roller wrapping machine wraps the combing roller, it is necessary to first fix the roller body to be wrapped on the three-jaw chuck, then knock one end of a sawtooth strip of a certain length into the threaded groove of the combing roller body, and use the extrusion wheel to press the end of the sawtooth strip tightly. Finally, the motor drives the three-jaw chuck and the roller body clamped on the three-jaw chuck to rotate synchronously. Since the sawtooth strip is spirally wound on the roller body, during this period, the extrusion wheel can move along the axial direction of the combing roller as the sawtooth strip is wound, until the wrapping is completed.

[0004] However, although the extrusion wheel in the above-mentioned combing roller wrapping machine has grooves on its surface for embedding the serrated portion of the serrated belt, allowing the extrusion wheel to move synchronously with the wrapping progress of the serrated belt, reducing manual intervention during the wrapping process and achieving a high degree of automation, the inventors found at least the following problems when implementing the above-mentioned combing roller wrapping machine: First, before the wrapping work begins, workers need to cut the serrated belt into small segments of a certain length, collect these segments in a container (usually a plastic box), and place them next to the combing roller wrapping machine for the workers to use. This preparation process is lengthy and cumbersome, which is detrimental to improving the efficiency of the combing roller wrapping machine; second, in order to ensure that the serrated belt can... The sawtooth strip is accurately and tightly wound onto the combing roller. During the winding process, the operator needs to hold the unwound end of the sawtooth strip, pull it upwards and apply a certain tension to make the sawtooth strip as tangent to the combing roller as possible. Furthermore, as the winding process progresses, the axial position of the sawtooth strip end on the combing roller needs to be changed. Throughout the process, the operator needs to maintain a high level of concentration, and the labor intensity is relatively high. At the same time, due to the structure of the sawtooth strip itself, accidents of operators being scratched by the sawtooth part of the strip occasionally occur. In view of this, the inventor, based on years of relevant design concepts and practical experience in this industry, has researched and improved the above-mentioned problems to provide a high-efficiency and safe combing roller winding machine. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency combing roller wrapping machine that can improve wrapping efficiency, reduce the labor intensity of workers during the wrapping process, and enhance the safety of equipment use. It solves the problems of existing combing roller wrapping machines having many and cumbersome preparation steps before wrapping, resulting in low efficiency of the combing roller wrapping machine, and the risk of workers being scratched by the saw teeth of the saw belt during the wrapping process.

The feeding container has a storage part adapted to accommodate the serrated strip in a coiled state and a feeding part communicating with the storage part. One end of the serrated strip located in the storage part moves through the feeding part and reaches the threaded groove outside the roll body to be wrapped.

[0007] Optionally, a mounting platform is provided on the top of the machine, a pressure roller mounting frame is provided on the mounting platform, a slider is provided at the bottom of the pressure roller mounting frame, a sliding hole is provided on the mounting platform to slide with the slider, the length direction of the sliding hole is perpendicular to the axis of the roller to be wrapped, a sliding rod is provided on the mounting platform with its length direction parallel to the axis of the roller to be wrapped, the extrusion roller is slidably sleeved outside the sliding rod, and a lead screw is rotatably provided on the mounting platform and threadedly connected to the pressure roller mounting frame.

[0008] Optionally, the extrusion wheel has a groove on its surface, and a plurality of rotatable friction-reducing balls are provided between the inner side of the extrusion wheel and the slide bar.

[0009] Optionally, the feeding container and the pressure roller mounting frame are connected by a sliding bracket. The first end of the sliding bracket is connected to the feeding container, and the second end of the sliding bracket is provided with a slider. The pressure roller mounting frame is provided with a sliding hole that slides with the slider. The length direction of the sliding hole is parallel to the axis of the roll body to be wrapped.

[0010] Optionally, the feeding section is a rod-shaped structure, with the first end of the feeding section connected to the storage section, and the second end of the feeding section located above the pressing part of the extrusion roller and the roll body to be wrapped and fixed to the sliding bracket.

[0011] Optionally, the upper part of the storage section is an open cylindrical shape, the lower part of the storage section is a conical shape, and the first end of the discharge section is connected to and communicates with the lower part of the storage section.

[0012] Optionally, the second end of the feeding section is provided with a correction end cover. One end of the correction end cover is connected to the feeding section, and the other end of the correction end cover is conical. A correction hole is opened at the conical end of the correction end cover, and the shape of the correction hole is adapted to the cross-sectional shape of the sawtooth belt.

[0013] Optionally, the sliding bracket is provided with a cutting mechanism, which includes a horizontally arranged blade and a cylinder mounted on the sliding bracket. The blade faces the end of the correction end cover that has a correction hole, and the blade is fixedly mounted on the output end of the cylinder.

[0014] Optionally, the cutting mechanism further includes a blade sheath, which is fitted over the blade and fixed to the sliding bracket by screws.

[0015] Optionally, the feeding section is provided with a tensioning mechanism, which includes two clamping blocks disposed in the mounting groove.

A limit plate is provided at the end of the adjusting screw located inside the connecting sleeve. The spring abuts against the limit plate and the clamping block.

[0016] Compared with the prior art, the present invention provides a high-efficiency combing roll wrapping machine with the following advantages: During the wrapping process, this invention eliminates the need for workers to manually straighten the toothed belt, reducing labor intensity and preventing accidents caused by the belt swaying during transport. After wrapping one roller, the wrapped portion of the toothed belt can be separated from the remaining portion using a cutting tool. This allows the toothed belt to be cut to the required length according to its actual use, without the need to pre-cut it into smaller segments. This reduces the number of steps in the wrapping process of the combing roller, thereby improving the efficiency of this high-efficiency combing roller wrapping machine. The present invention sets the upper part of the storage section as an open cylindrical shape and the lower part as a conical shape. The overall shape of the saw blade after coiling is circular, so that it can be placed into the upper part of the storage section. The conical lower part of the storage section can reduce the degree of bending of the saw blade when it enters the discharge section from the storage section, thus avoiding damage to the saw blade's own structure. This invention features a cutting mechanism mounted on a sliding bracket. When a combing roller is completed, the operator can control the extension and retraction of the cylinder in the cutting mechanism via a switch, thereby using a blade to cut the toothed strip, making it more convenient to use.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Please refer to Figures 1 to 9The present invention provides a technical solution: a high-efficiency combing roller wrapping machine, comprising: a machine base 1, on which a positioning drive mechanism is provided for positioning and clamping the roll body 2 to be wrapped and for driving the roll body 2 to be wrapped to rotate. The positioning drive mechanism may include a three-jaw chuck 25 and a drive motor for driving the three-jaw chuck 25 to rotate. The cooperation between the three-jaw chuck 25 and the drive motor is prior art and will not be described in detail here; a pressing roller 3, which is movably mounted on the machine base 1 and is adapted to press the toothed strip 5 against the threaded groove outside the roll body 2 to be wrapped; and a feeding assembly, the feeding assembly including a feeding container 4 disposed above the pressing part of the pressing roller 3 and the roll body 2 to be wrapped and movable along the axial direction of the roller body. The feeding container 4 has a storage part 40 adapted to accommodate the coiled toothed strip 5 and a feeding part 41 communicating with the storage part 40. One end of the toothed strip 5 located in the storage part 40 moves through the feeding part 41 to reach the threaded groove outside the roll body 2 to be wrapped. Before the combing roller wrapping operation, the operator places the coiled sawtooth strip 5 into the storage section 40 of the feeding container 4, and presses one end of the coiled sawtooth strip 5 through the feeding section 41 into the threaded groove on the roller body 2 to be wrapped. During the wrapping operation, the sawtooth strip 5 is continuously and automatically output from the feeding section 41 of the feeding container 4. During the wrapping process, the operator does not need to manually straighten the sawtooth strip 5, which not only reduces the labor intensity of the operator, but also avoids the accident of the sawtooth strip 5 scratching the operator due to the swaying of the conveyor. After the wrapping of one roller body is completed, the wrapped part of the sawtooth strip 5 can be cut from the remaining part using a cutting tool. In this way, the sawtooth strip 5 can be cut to the required length according to the actual use of the sawtooth strip 5, and there is no need to cut the sawtooth strip 5 into several small sections in advance. This reduces the steps of the combing roller wrapping process, thereby helping to improve the wrapping efficiency of the high-efficiency combing roller wrapping machine.

[0021] To achieve the extrusion of the toothed belt 5 by the extrusion roller 3, in this embodiment, a mounting platform 22 is provided on the top of the machine base 1. A pressure roller mounting bracket 6 is provided on the mounting platform 22, and a slider 7 is provided at the bottom of the pressure roller mounting bracket 6. A sliding hole 8 is provided on the mounting platform 22 to slide and engage with the slider 7. The length direction of the sliding hole 8 is perpendicular to the axis of the roller body 2 to be wrapped. A sliding rod 9 is provided on the mounting platform 22, with its length direction parallel to the axis of the roller body 2 to be wrapped. The extrusion roller 3 is slidably sleeved outside the sliding rod 9. A lead screw 10 is rotatably mounted on the mounting platform 22 and threadedly connected to the pressure roller mounting bracket 6. Specifically, the lead screw... A handwheel 24 can also be provided at one end of 10. After pressing one end of the toothed strip 5 into the threaded groove on the outside of the roll body 2 to be wrapped, the operator can rotate the screw 10 by turning the handwheel 24. The screw 10 drives the pressure roller mounting bracket 6 to move radially along the roll body 2 to be wrapped, thereby pushing the extrusion roller 3 to move closer to the roll body 2 to be wrapped, until the toothed strip 5 is pressed into the threaded groove on the outside of the roll body 2 by the extrusion roller 3. Of course, in other embodiments, the extrusion roller 3 can also be driven to move by an electric push rod or a hydraulic cylinder to extrude the toothed strip 5, or even by manual driving.

[0022] To reduce the resistance to the movement of the extrusion roller 3, in this embodiment, a groove 11 is provided on the surface of the extrusion roller 3, and a plurality of rotatable anti-friction balls 12 are provided between the inner side of the extrusion roller 3 and the slide rod 9. Specifically, as shown in the figure... Figure 9 As shown, the number of friction-reducing balls 12 can be set to six. The inner side of the extrusion wheel 3 is provided with a slot 30 for installing the friction-reducing balls 12. The six friction-reducing balls 12 are distributed around the slot 30 of the extrusion wheel 3. A cover 23 is provided at the opening of the slot 30 to encapsulate the friction-reducing balls 12 in the slot 30. The cover 23 is fixed to the extrusion wheel 3 by screws, which facilitates the subsequent disassembly and replacement of the friction-reducing balls 12 in the groove 11. The setting of the friction-reducing balls 12 can reduce the frictional resistance when the extrusion wheel 3 moves along the slide bar 9, so that the extrusion wheel 3 moves more smoothly on the slide bar 9.

[0023] In this embodiment, the feeding container 4 and the pressure roller mounting frame 6 are connected by a sliding bracket 13. The first end of the sliding bracket 13 is connected to the feeding container 4, and the second end of the sliding bracket 13 is provided with a slider 14. The pressure roller mounting frame 6 is provided with a sliding hole 15 that slides with the slider 14. The length direction of the sliding hole 15 is parallel to the axis of the roller body 2 to be wrapped. Specifically, as shown... Figure 4 As shown, the sliding bracket 13 has an L-shaped structure, and the slider at the second end of the sliding bracket 13 adopts a dovetail structure. Correspondingly, the sliding hole 15 on the pressure roller mounting bracket 6 is a dovetail groove. In at least one embodiment, a handle 20 is provided on the sliding bracket. The operator drives the sliding bracket 13 to move through the handle 20, so that the sliding bracket 13 can move synchronously with the movement of the extrusion roller 3, thereby enabling the sawtooth belt 5 to maintain a vertical state and be tangent to the roll body 2 to be wrapped.

[0024] In this embodiment, the feeding section 41 is a rod-shaped structure. The first end of the feeding section 41 is connected to the storage section 40, and the second end of the feeding section 41 is located above the pressing part of the extrusion roller 3 and the roll body 2 to be wrapped and is fixed to the sliding bracket 13. Specifically, as shown in the figure... Figure 2 As shown, the feeding part 41 is a circular hollow rod, preferably made of stainless steel tube. In other embodiments, the feeding part 41 may also be a square tube or other polygonal tube.

[0025] To facilitate the conveying of the toothed belt 5, in this embodiment, the upper part of the storage section 40 is an open cylindrical shape, and the lower part of the storage section 40 is a conical shape. The first end of the discharge section 41 is connected to and communicates with the lower part of the storage section 40. The toothed belt 5, after being coiled, has an overall circular shape, which allows it to be placed into the upper part of the storage section 40. The conical lower part of the storage section 40 reduces the degree of bending of the toothed belt 5 when it enters the discharge section 41 from the storage section 40, thus avoiding damage to the structure of the toothed belt 5. In at least one other embodiment, such as Figure 3 As shown, a cover plate 21 is provided at the upper opening of the storage section 40. Since the toothed belt 5 has a certain elasticity, it is easy for the toothed belt 5 to pop out from the storage section 40 during the conveying process. By using the cover plate 21 to enclose the toothed belt 5 in the storage section 40, it can be prevented from popping out from the storage section 40, thus ensuring the stability of the toothed belt 5 during the conveying process. Specifically, the cover plate 21 can be hinged to the storage section 40 by a hinge or hinge, which facilitates the opening and closing of the cover plate 21.

[0026] In this embodiment, a correction end cap 16 is provided at the second end of the feeding section 41. One end of the correction end cap 16 is connected to the feeding section 41, and the other end of the correction end cap 16 is conical. A correction hole 17 is provided at the conical end of the correction end cap 16. The shape of the correction hole 17 is adapted to the cross-sectional shape of the sawtooth belt 5. The correction hole 17 can keep the sawtooth belt 5 at a fixed angle when it is output, which makes it easier for the sawtooth belt 5 to be embedded in the threaded groove of the roller body 2 to be wrapped. 5. Continuous movement within the correction hole 17 can easily cause deformation of the correction hole 17. To facilitate replacement, the correction end cover 16 and the feeding part 41 can be detachably connected. Specifically, an external thread 160 can be provided at one end of the correction end cover 16 connected to the feeding part 41, and an internal thread that matches the external thread 160 on the correction end cover 16 can be provided on the feeding part 41, so that the correction end cover 16 and the feeding part 41 can be detached, which facilitates the later replacement of the correction end cover 16.

[0027] In this embodiment, a cutting mechanism is provided on the sliding bracket 13. The cutting mechanism includes a horizontally arranged blade 180 and a cylinder 181 mounted on the sliding bracket 13. The blade 180 faces the end of the correction end cover 16 which is provided with a correction hole 17. The blade 180 is fixedly mounted on the output end of the cylinder 181. Specifically, the cylinder 181 is controlled to extend and retract by a switch. When the wrapping of a combing roller is completed, the operator can control the extension and retraction of the cylinder 181 by the switch, thereby using the blade 180 to cut the toothed belt 5.

[0028] To improve the safety of this high-efficiency combing roller wrapping machine, in this embodiment, the cutting mechanism also includes a blade sleeve 182. The blade sleeve 182 is fitted outside the blade 180 and fixed to the sliding bracket 13 by screws. When the cylinder 181 controls the blade 180 to extend, it can cut the toothed strip 5. After the cutting is completed, the cylinder 181 drives the blade 180 to retract into the blade sleeve 182 to prevent the blade 180 from being exposed and accidentally injuring the workers.

[0029] To enable the toothed strip 5 to wrap more tightly around the roll body 2 to be wrapped, in this embodiment, a tensioning mechanism 19 is provided on the feeding section 41. The tensioning mechanism 19 includes two clamping blocks 190 disposed in the mounting groove 410. The feeding section 41 has a through-hole for mounting the two clamping blocks 190. A connecting frame 191 is fixedly mounted on the outer wall of the feeding section 41 at the position corresponding to the mounting groove 410. An adjusting screw 192 is threadedly connected to the connecting frame 191. A connecting sleeve 193 is provided at the end of the clamping block 190 facing the adjusting screw 192. A spring 194 is provided inside the connecting sleeve 193. The first end of the adjusting screw 192 is movably inserted into the connecting sleeve 193. A limit plate 1 is provided at the end of the adjusting screw 192 located inside the connecting sleeve 193. 95. Spring 194 is pressed between the limiting plate 195 and the clamping block 190. Under the elastic force of spring 194, the two clamping blocks 190 clamp the two sides of the toothed belt 5 with a certain force, so that the end of the toothed belt 5 connected to the roller body 2 to be wrapped can be straightened, thereby improving the tightness of the toothed belt 5 wrapped around the roller body 2 to be wrapped. When it is necessary to adjust the clamping force of the clamping block 190 on the toothed belt 5, it can be achieved by turning the adjusting screw 192. In at least one embodiment, in order to facilitate the toothed belt 5 to pass through the feeding part 41, an inclined surface 1900 is provided above the clamping block 190. The toothed belt 5 will pass through the gap between the two clamping blocks 190 under the guidance of the inclined surface 1900. In order to reduce the friction between the clamping block 190 and the toothed belt 5, such as Figure 6 , Figure 7 and Figure 8 As shown, a roller 196 can also be provided on one side of the clamping block 190 that clamps the toothed belt 5. The clamping block 190 makes rolling contact with the toothed belt 5 through the roller 196, which can reduce the wear of the toothed belt 5 on the clamping block 190.

[0030] Working principle: Before wrapping the combing rollers using this high-efficiency combing roller wrapping machine, the operator places the coiled sawtooth strip 5 into the storage section 40 of the feeding container 4, and presses one end of the coiled sawtooth strip 5 through the feeding section 41 into the threaded groove on the roller body 2 to be wrapped. Then, the cover plate 21 is closed over the opening at the top of the storage section 40. During the wrapping operation, the roller body 2 to be wrapped is first fixed on the three-jaw chuck 25, and then the end of the sawtooth strip 5 extending from the feeding section 41 is fixed in the threaded groove on the outside of the roller body 2 to be wrapped. Next, the handwheel 24 is rotated to drive the lead screw 10 to rotate, so that the pressure roller mounting frame 6 approaches the roller body to be wrapped. The roller 2 moves to one side until the extrusion wheel 3 presses the serrated strip 5 on the roller 2 to be wrapped. Finally, the motor drives the roller 2 to be wrapped to rotate. At this time, the serrated strip 5 is continuously and automatically output from the feeding part 41 of the feeding container 4. During the wrapping process, the extrusion wheel 3 moves along the length of the slide bar 9 as the wrapping work progresses until the wrapping is completed. After the wrapping work of one roller is completed, the operator can control the cylinder 181 to extend and retract through the switch and use the blade 180 to cut the serrated strip 5. Finally, the wrapped combing roller can be removed from the three-jaw chuck 25. The above is the working process of this high-efficiency combing roller wrapping machine.
