Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a belt winding device. Background Technology

[0002] Underground conveyor belt winding devices are commonly used equipment in underground operations such as mining, oil, and chemical industries. They are primarily used to wind up conveyor belts, helping to maintain the neatness and efficient operation of underground equipment. This device helps manage the length of the underground conveyor belt, control its movement, and ensure the stability of the underground equipment. It also effectively prevents problems such as belt slack and tangling during use. During the longwall mining process, the length of the conveyor belt needs to be continuously adjusted and contracted. When the belt storage bin reaches saturation, the belt must be retrieved promptly. In this process, the belt winding device plays a crucial role.

[0003] However, existing belt winding devices have certain limitations in practical applications. Due to the varying widths of conveyor belts used in different working environments, existing devices often cannot effectively limit the offset at both ends of the belt during the winding process. This problem causes the belt to shift during winding, requiring manual correction. If the belt shifts during winding, it will be subjected to uneven tension or friction, leading to excessive wear or damage to certain parts of the belt, reducing its service life. Belt shift will cause the wound belt to form an irregular shape, which will affect subsequent storage, transportation, and use. If the belt roll is not neat, it will be difficult to unwind smoothly, increasing the difficulty of use. Utility Model Content

[0004] The purpose of this utility model is to provide a belt winding device to solve the problem that existing devices often cannot effectively limit the deviation of the two ends of the belt during the winding process due to the different widths of conveyor belts used in different working environments. This problem causes the belt to deviate during winding, requiring manual correction. If the belt deviates during winding, it will be subjected to uneven tension or friction, resulting in excessive wear or damage to some parts of the belt, reducing its service life. Belt deviation will cause the wound belt to be rolled into an irregular shape, which will affect subsequent storage, transportation and use. If the belt roll is not neat, it will be difficult to unwind smoothly, increasing the difficulties in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt winding device, comprising a support frame, a rotating shaft, a pressing device, sliding rings, and an adjusting device. The support frame is symmetrically arranged, with its bottom end in contact with the ground. The top ends of the support frames on the left and right sides are connected by a rotating shaft. The rotating shaft is a cylindrical shell with an opening to the left. The closed end of the rotating shaft is connected to the output end of a pulley, on which a belt is wound. The input end of the pulley is connected to the output end of a drive motor. The left and right ends of the rotating shaft are symmetrically connected to limit rings, and two sliding rings are provided between the limit rings, fitted onto the rotating shaft and slidably engaged with it. An adjusting device is connected to the sliding ring and located at the open end of the rotating shaft. A pressing device is connected to the contact end between the sliding ring and the rotating shaft.

[0006] The clamping device includes a lower pressure rod, a return spring, and a clamping plate. A positioning groove is provided on the sliding ring, and a through hole is provided at the top of the positioning groove. The lower pressure rod is connected to the through hole and slidably fitted into the sliding ring. A limit plate is connected to the top of the lower pressure rod, and a clamping plate is connected to its bottom end. The bottom end of the clamping plate is tightly fitted to the outer circumference of the rotating shaft. A return spring is provided between the clamping plate and the top of the positioning groove, sleeved on the lower pressure rod, with one end abutting against the top of the clamping plate and the other end abutting against the top of the positioning groove.

[0007] The adjusting device includes a bidirectional threaded rod, a slider, and a connecting rod. The front and rear ends of the rotating shaft are symmetrically provided with sliding grooves, and a connecting rod is provided on each of the sliding grooves. One end of the connecting rod is connected to a sliding ring, and the other end is connected to a slider, which slides and engages with the rotating shaft. The slider is provided with an internal threaded hole, and the internal threaded holes of the two sliders rotate in opposite directions. The internal threaded holes engage with the bidirectional threaded rod. One end of the bidirectional threaded rod abuts against the inner wall of the rotating shaft, and the other end is connected to an adjusting handwheel.

[0008] Preferably, the contact ends of the bidirectional threaded rod and the rotating shaft are respectively connected to bearing seats.

[0009] Preferably, the contact end between the clamping plate and the rotating shaft is arc-shaped, and the arc-shaped end is in close contact with the outer circumference of the rotating shaft.

[0010] Preferably, the left and right ends of the clamping plate abut against the corresponding end faces of the limiting ring.

[0011] Preferably, the internal threads of the two sliders are in opposite directions and are configured to correspond to a bidirectional threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By connecting two adjustable sliding rings to the winding shaft, the distance between the sliding rings can be adjusted according to the belt width, thereby effectively limiting the two ends of the belt during winding and preventing belt deviation. The adjustment device is installed at the open end of the shaft. By rotating the bidirectional threaded rod, the slider moves relative to the belt, which in turn drives the two sliding rings to move synchronously, precisely adjusting the distance between the sliding rings. Each sliding ring is also connected to a pressure plate. When the belt is winding, lifting the lower pressure rod causes the return spring to abut against the inner wall of the through hole, causing the pressure plate to rise synchronously and fix one end of the belt. Then, releasing the lower pressure rod causes the pressure plate to return to its original position, thus firmly clamping the belt. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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] Example 1: Please refer to Figure 1-4 This utility model provides an embodiment of a belt winding device, comprising a support frame 1, a rotating shaft 2, a pressing device 3, a sliding ring 4, and an adjusting device 5. The support frames 1 are symmetrically arranged, with their bottom ends contacting the ground. The top ends of the support frames 1 on both sides are connected via the rotating shaft 2. Bearing seats are connected to the contact ends of the support frames 1 and the rotating shaft 2, respectively, for supporting and positioning the rotating shaft 2 and providing rotation, reducing friction, and leaving a gap between the support frames 1 and the ground to accommodate the diameter of the wound belt, while also providing stable support for the device and increasing overall stability. The rotating shaft 2 is a cylindrical shell with an opening to the left. The closed end of the rotating shaft 2 is connected to the output end of a pulley, on which a belt is wound. The input end of the pulley is connected to the output end of a drive motor. The rotating shaft 2 is the core transmission shaft of the entire device, supporting the key rotating components. The closed end of shaft 2 is connected to the drive motor via a pulley for rotation. When the belt is placed on shaft 2, it is wound up. An adjustment device 5 is housed inside. The left and right ends of shaft 2 are symmetrically connected to limit rings 6. Two sliding rings 4 are positioned between the limit rings 6. The sliding rings 4 are used to adjust the spacing between belts of different widths during winding. This allows the corresponding ends of the sliding rings 4 to limit the two ends of the belt, ensuring the belt winds along the shaft 2 between the sliding rings 4. This prevents the belt from shifting during winding, thus avoiding an irregular shape after winding. The belt is fitted onto shaft 2 and slidably engaged with it. The adjustment device 5 is connected to the sliding ring 4 and located at the open end of shaft 2. A clamping device 3 is connected to the contact end between the sliding ring 4 and shaft 2.

[0024] The clamping device 3 includes a lower pressure rod 301, a return spring 302, and a clamping plate 303. A positioning groove is provided on the sliding ring 4, and a through hole is provided at the top of the positioning groove. The lower pressure rod 301 is connected to the through hole and is connected to the clamping plate 303. The movement of the lower pressure rod 301 causes the clamping plate 303 to move away from or against the outer circumference of the rotating shaft 2, thereby clamping the end of the belt for winding. It also slides within the sliding ring 4. A limit plate is connected to the top of the lower pressure rod 301 to prevent it from exceeding a predetermined range. The clamping plate 303 is connected to the bottom end of the lower pressure rod 301. The width of the clamping plate 303 corresponds to the width of the positioning groove. The bottom end of the clamping plate 303 is tightly fitted against the outer circumference of the rotating shaft 2. The contact end between the clamping plate 303 and the rotating shaft 2 is arc-shaped. The curved end of the pressure plate 303 fits tightly against the outer circumference of the rotating shaft 2, thereby clamping the end of the belt between the rotating shaft 2 and the pressure plate 303, ensuring the stability of the belt at the start of the winding operation. A return spring 302 is provided between the pressure plate 303 and the top of the positioning groove. The return spring 302 is used to lift the lower pressure rod 301 and, when the lower pressure rod 301 is released, drive the lower pressure rod 301 to return to its original position, thereby pressing the pressure plate 303 against the top of the belt. The pressure plate 303 is sleeved on the lower pressure rod 301, with one end abutting against the top of the pressure plate 303 and the other end abutting against the top of the positioning groove. The left and right ends of the pressure plate 303 abut against the corresponding end faces of the limiting ring 6, respectively, to cope with the pressing operation of belts of different widths.

[0025] The adjusting device 5 includes a bidirectional threaded rod 501, a slider 502, and a connecting rod 503. The front and rear ends of the rotating shaft 2 are symmetrically provided with sliding grooves, which are set to correspond to the distance between the two limiting rings 6. Connecting rods 503 are respectively provided on the sliding grooves. The connecting rods 503 are used to connect the sliding rings 4 to the sliders 502, so that when the bidirectional threaded rod 501 drives the sliders 502 to move relative to each other, the sliding rings 4 move synchronously, thereby adjusting the distance between the two sliding rings 4. One end of the connecting rod 503 is connected to the sliding rings 4, and the other end is connected to the slider 502, which slides on the rotating shaft 2. The slider 502 has an internal threaded hole, which is connected to the external thread of the bidirectional threaded rod 501. The two-way threaded rods 501 are interconnected, and since they are composed of two threaded rods with opposite directions of rotation, the sliders 502 at both ends cooperate with their corresponding threaded rods. The internal threaded holes of the two sliders 502 have opposite directions of rotation, and the internal threaded holes are engaged with the two-way threaded rods 501. One end of the two-way threaded rod 501 abuts against the inner wall of the rotating shaft 2, and the other end is located at the open end. Bearing seats are connected to both contact ends. The threaded cut-off ends at both ends provide support and positioning for the two-way threaded rod 501, while also allowing rotation and reducing friction. The open end is driven by an adjusting handwheel, and the other end is connected to an adjusting handwheel.

[0026] In use, first pull up the lower pressure rod 301, which simultaneously compresses the return spring 302, causing the pressure plate 303 to rise. Place one end of the belt between the pressure plate 303 and the rotating shaft 2. Then release the lower pressure rod 301. The pressure plate 303 returns to its original position due to the force of the return spring 302, clamping the belt. Then rotate the adjusting handwheel to rotate the bidirectional threaded rod 501, causing the two sliders 502 to narrow their distance, allowing the two sliding rings 4 to slide on the rotating shaft 2, reducing the distance between them and limiting both ends of the belt. Then start the drive motor to rotate the rotating shaft 2, thereby winding the belt.

[0027] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
