Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, specifically a mining tape winding machine. Background Technology

[0002] Mining conveyor belts mainly refer to various conveyor belts used in underground conveying machinery. They are usually tens of meters long and one meter wide. After use, they need to be rolled up and brought to the shaft. Since manual winding requires 5 to 6 people to complete, and the operation is time-consuming and labor-intensive, existing technology mostly uses a winding machine to complete the winding operation.

[0003] The specific operation involves first fixing one end of the tape to be wound onto the winding shaft of the tape winding machine, and then driving the winding shaft to rotate via a drive motor. This, along with the rotating shaft located on the front side, restricts the movement trajectory of the tape to be wound, preventing the tape from flipping or shifting.

[0004] While the aforementioned equipment can effectively complete the tape winding process, in actual operation, the tapes being wound are mostly used tapes. Furthermore, the environment in mines is harsh and humid, and the surface of the used tapes often has various hard or even sharp debris, such as ores and metal shavings, adhering to it. Since the tapes mostly pass under the rotating shaft and roll in conjunction with it, the parallel rotating shaft will trap some of these hard debris at its location during rotation. This debris cannot be discharged quickly, and as it accumulates, it easily scratches subsequent tapes under the pressure of the rotating shaft, accelerating wear on both the tape and the shaft, thus shortening their service life. Utility Model Content

[0005] The purpose of this utility model is to provide a mining tape winding machine to solve the problems mentioned in the background art.

[0007] A tape reel unit is disposed on the base and is used to reel in the tape to be rolled; the tape reel unit includes a pair of support frames symmetrically disposed on the base, a take-up shaft is rotatably disposed between the two support frames, and a drive device is disposed on the base to drive the take-up shaft to rotate in a set direction;

[0008] A foolproof unit is disposed on the base and is used to limit the travel trajectory of the tape to be wound up; the foolproof unit includes a rotating shaft rotatably disposed on the base, and the rotating shaft is disposed at a set angle.

[0010] Preferably, two support seats are fixedly installed on the base, and the height of one of the support seats relative to the upper surface of the base is lower than that of the other support seat. The two ends of the rotating shaft are respectively rotatably connected to the corresponding support seats, so that the rotating shaft is inclined relative to the winding shaft.

[0011] Preferably, an inclined mounting plate is fixedly connected to the lower support seat 2, a central shaft is rotatably mounted on the mounting plate, a friction wheel is fixedly mounted on the shaft of the central shaft, the friction wheel is in drive engagement with the belt body at the corresponding position of the tape during winding, and at least one discharge plate is fixedly mounted on the top end of the central shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention employs a combination of a rotating shaft and a friction wheel. By utilizing the tilted rotating shaft to change the tilt angle of the belt during winding, the trapped hard debris slides along the belt towards the lower side of the rotating shaft under the influence of gravity. This, combined with the rotation of the discharge plate on the central shaft driven by the moving belt, quickly discharges the hard debris accumulated on the upper side of the belt. This effectively prevents the debris from being crushed by the rotating shaft, thus avoiding accelerated wear and tear on the belt and belt body. This overcomes the shortcomings of existing technologies and improves the practicality of the equipment. Attached Figure Description

[0024] 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. Example

[0025] Please see Figure 1-2 This utility model provides a technical solution:

[0026] A mining tape winding machine includes a base 100 and a winding unit 200 disposed on the base 100 for winding tape to be wound. The winding unit 200 includes a pair of support frames 201 symmetrically disposed on the base 100, and a winding shaft 202 rotatably disposed between the two support frames 201. A driving device is disposed on the base 100 for driving the winding shaft 202 to rotate in a set direction.

[0027] A foolproof unit 300, disposed on the base 100, is used to limit the travel trajectory of the tape to be wound. The foolproof unit 300 includes a rotating shaft 301 rotatably disposed on the base 100, and the rotating shaft 301 is set at a predetermined angle. Two support seats 302 are fixedly mounted on the base 100. The two ends of the rotating shaft 301 are respectively rotatably connected to the top of the corresponding support seat 302, and the two support seats 302 are at the same height, so that the winding shaft 202 is arranged parallel to the rotating shaft 301.

[0028] The drive unit includes a servo motor 203 fixedly mounted on the base 100. A small synchronous pulley 204 is fixedly connected to the output shaft of the servo motor 203. A synchronous shaft 205 is rotatably mounted on a support frame 201 near the small synchronous pulley 204. A large synchronous pulley 206 is fixedly mounted on one side of the synchronous shaft 205. The large synchronous pulley 206 and the small synchronous pulley 204 are driven by a synchronous belt 207. Flanges 208 are fixedly mounted on opposite sides of the synchronous shaft 205 and the take-up shaft 202, and the two flanges 208 are detachably connected together. The end of the take-up shaft 202 away from the flange 208 is rotatably connected to the corresponding support frame 201, and the upper side of the support frame 201 is open. A guide unit 400 is also provided on the base 100. The guide unit 400 includes a pair of support seats 401 fixedly mounted on the base 100. A positioning shaft 402 is provided above the base 100, and both ends of the positioning shaft 402 are rotatably connected to the corresponding support seats 401.

[0029] Working principle: Before use, first check whether all parts of the equipment are functioning properly. After checking, first pass one end of the tape to be wound through the underside of the rotating shaft 301, at an angle parallel to the winding shaft 202, and clamp it tightly onto the winding shaft 202. The winding shaft 202 is usually equipped with a tape clamping component, which is existing technology and will not be described in detail here. After clamping, start the servo motor 203. The output shaft of the servo motor 203 rotates, driving the small synchronous pulley 204 to rotate. The step wheel 204 drives the large synchronous pulley 206 to rotate at a differential speed via the synchronous belt 207, which in turn drives the synchronous shaft 205 to rotate synchronously. The synchronous shaft 205 drives the take-up shaft 202 to rotate via the flange 208, thereby winding the tape. During the movement, the upper surface of the tape body is pressed against the rotating shaft 301, which in turn drives the rotating shaft 301 to rotate. As the rotating shaft 301 rotates, it restricts the movement trajectory of the tape body, which can effectively prevent it from flipping over or deviating too much, thus ensuring the smooth progress of the winding operation.

[0030] In an optional embodiment, a positioning shaft 402 can be added to the base 100. One end of the tape passes under the rotating shaft 301 and then passes over the positioning shaft 402, so that the lower surface of the tape is attached to the middle of the shaft of the positioning shaft 402. Since the shaft diameters at both ends of the positioning shaft 402 are large, the offset range of the moving tape can be stably limited to the middle position of the positioning shaft 402, which can further prevent the tape from deviating too much during winding and improve the practicality of the device. Example

[0031] Please see Figure 3-4 This utility model provides another technical solution:

[0032] A mining tape winding machine includes a base 100 and a winding unit 200 disposed on the base 100 for winding tape to be wound. The winding unit 200 includes a pair of support frames 201 symmetrically disposed on the base 100, and a winding shaft 202 rotatably disposed between the two support frames 201. A driving device is disposed on the base 100 for driving the winding shaft 202 to rotate in a set direction. A foolproof unit 300 is disposed on the base 100 for limiting the travel trajectory of the tape to be wound. The foolproof unit 300 includes a rotating shaft 301 rotatably disposed on the base 100, and the rotating shaft 301 is set at a set angle.

[0033] Two support seats 303 are fixedly installed on the base 100, and the height of one support seat 303 relative to the upper surface of the base 100 is lower than that of the other support seat 303. The two ends of the rotating shaft 301 are rotatably connected to the corresponding support seat 303, so that the rotating shaft 301 is inclined relative to the winding shaft 202.

[0034] An inclined mounting plate 304 is fixedly connected to the lower support 303. A central shaft 305 is rotatably mounted on the mounting plate 304. A friction wheel 306 is fixedly mounted on the shaft of the central shaft 305. The friction wheel 306 is in drive engagement with the belt body at the corresponding position of the tape during winding. At least one discharge plate 307 is fixedly mounted on the top of the central shaft 305.

[0035] The end of the discharge plate 307 away from the central shaft 305 is bent. The drive device includes a servo motor 203 fixedly mounted on the base 100. A small synchronous pulley 204 is fixedly connected to the output shaft of the servo motor 203. A synchronous shaft 205 is rotatably mounted on the support frame 201 near the small synchronous pulley 204. A large synchronous pulley 206 is fixedly mounted on one side of the synchronous shaft 205. The large synchronous pulley 206 and the small synchronous pulley 204 are driven by a synchronous belt 207. Flanges 208 are fixedly mounted on opposite sides of the synchronous shaft 205 and the take-up shaft 202, and the two flanges 208 are detachably connected together. The end of the take-up shaft 202 away from the flange 208 is rotatably connected to the corresponding support frame 201, and the upper side of the support frame 201 is open.

[0036] The base 100 is also provided with a guide unit 400, which includes a pair of support seats 401 fixedly installed on the base 100. A positioning shaft 402 is provided above the base 100, and the two ends of the positioning shaft 402 are rotatably connected to the corresponding support seats 401.

[0037] Working principle:

[0038] Before use, first check whether each part of the equipment can be used normally. After the check is completed, first pass one end of the tape to be wound through the bottom of the rotating shaft 301, then through the top center of the positioning shaft 402, and finally, at an angle parallel to the winding shaft 202, press it tightly and clamp it on the winding shaft 202. The winding shaft 202 is usually equipped with a component for clamping the tape. This is existing technology, so it will not be described in detail here.

[0039] After clamping, the servo motor 203 is started. The output shaft of the servo motor 203 rotates, driving the small synchronous pulley 204 to rotate. The small synchronous pulley 204 drives the large synchronous pulley 206 to rotate differentially through the synchronous belt 207, which in turn drives the synchronous shaft 205 to rotate synchronously. The synchronous shaft 205 drives the winding shaft 202 to rotate through the flange 208, winding up the tape. During the movement, the upper surface of the tape body is pressed against the rotating shaft 301, which in turn drives the rotating shaft 301 to rotate. While the rotating shaft 301 and the positioning shaft 402 are rotating, the movement trajectory of the tape body is restricted, which can effectively prevent it from turning over or deviating too much, thus ensuring the smooth progress of the winding work.

[0040] Meanwhile, since the rotating shaft 301 is set at an angle, the lower end of the rotating shaft 301 can press down the corresponding side of the tape, so that the hard debris left on the tape will slide to the lower side and accumulate under the action of gravity. It should be noted that the tilt angle of the rotating shaft 301 should generally not exceed 5°, so as to avoid the other side of the tape not being able to fully fit with the rotating shaft 301, causing the tape and the rotating shaft 301 to change from surface contact to line contact, which will affect the smooth progress of the winding work.

[0041] At the same time, the tape body on the side that is pressed down abuts against the friction wheel 306, causing the friction wheel 306 and the central shaft 305 to rotate synchronously, which in turn causes the discharge plate 307 on the central shaft 305 to rotate synchronously. Since the tape will vibrate slightly during the winding process, it will cause the hard debris accumulated on its upper side to jump. Since the discharge plate 307 is close to the upper surface of the tape, the bent end of the rotating discharge plate 307 can push the debris accumulated nearby away from the tape one after another, effectively reducing the wear of the tape caused by hard debris, and thus extending the service life of the tape.
