Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor tearing and recycling technology, and in particular relates to a belt conveyor tearing and recycling device. Background Technology

[0002] Belt conveyors are industrial conveying devices used to transport materials. Because they can transport various types of materials over heights and long distances, they are widely used in industry.

[0003] Belt conveyors rely on rubber belts for operation, especially large belt conveyors. These rubber belts, which transport materials and directly bear the weight of the materials, are considered consumables. During operation, especially with large belt conveyors, if the belt is torn longitudinally, and this tear is not detected in time, the entire belt becomes unusable.

[0004] For belts used with large conveyor belts, characterized by their large width and length, existing technologies often recycle them for economic reasons. This can be achieved by cutting the belts into narrower widths suitable for use on smaller conveyor belts. This process reuses waste while reducing economic losses. Specifically, for manufacturing enterprises, the types and applications of conveyor belts vary depending on the materials being transported. Since belts are consumable items, recycling and processing the waste belts from large conveyor belts for use on smaller ones would significantly reduce the economic costs of using conveyor belts for enterprises.

[0005] The current recycling method involves winding the waste belt between a belt unwinding and rewinding device, and then cutting it with a cutting blade during belt transport. However, because rubber belts are flexible, they tend to buckle downwards during unwinding and rewinding, often resulting in incomplete cuts by the cutting blade. Therefore, in actual operation, unless the cutting force between the belt and the cutting structure is increased, it is difficult to fully and completely cut belts of a certain thickness and strength. Utility Model Content

[0006] Based on the above background, the purpose of this utility model is to provide a belt conveyor tear recovery device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A belt conveyor belt tearing and recycling device includes a frame, with a belt unwinding mechanism and a belt winding mechanism respectively mounted and connected to the top two ends of the frame; it also includes a belt cutting mechanism installed on the frame.

[0009] It also includes several belt lifting and feeding mechanisms that cooperate with the belt cutting mechanism;

[0010] The belt lifting and tensioning mechanism includes a long rotating shaft hinged to the lower end of the frame, and a number of lifting wheel structures are fixedly installed on the long rotating shaft;

[0011] It also includes a push structure that drives the long shaft to rotate, and by rotating the long shaft, the lifting wheel structure is raised to lift the tension belt.

[0012] Preferably, the belt cutting mechanism includes brackets fixedly installed on both sides of the top of the frame, with several bracket rods detachably installed between the brackets, and several cutting blades slidably connected between the bracket rods.

[0013] Preferably, the cutter includes a sliding adjustment seat slidably connected between the support rods, and the bottom of the sliding adjustment seat is fixedly connected to the cutter;

[0014] The support rod is threaded with several adjusting nuts, which are respectively positioned on both sides of the sliding adjustment seat.

[0015] Preferably, locking nuts are installed at both ends of the support rod;

[0016] The cutter is shaped like an oblique triangle, and the direction of the cutter's inclination is the same as the direction of belt transmission.

[0017] Preferably, a pair of symmetrically arranged belt lifting and feeding mechanisms are assembled and connected to the lower end of the frame; the belt cutting mechanism is located between the belt lifting and feeding mechanisms.

[0018] Preferably, the lower ends of the frame are respectively fixedly connected to the two sides of the rotating shaft bracket, and the two ends of the rotating shaft are respectively equipped with a push structure;

[0019] The actuation structure includes an actuation cylinder hinged to the frame.

[0020] Preferably, push seats are fixedly connected to both ends of the long rotating shaft, and a push rod is fixedly connected to the piston rod of the push cylinder, and a hinge sleeve hinged to the push seat is fixedly connected to the push rod.

[0021] The top of the cylinder of the push cylinder is fixedly connected to a hinge plate, and the hinge plate is hinged to a hinge bracket, which is fixedly connected to the frame.

[0022] Preferably, the lifting wheel structure includes an lifting wheel, the wheel frame of which is fixedly connected to an lifting arm, and the lifting arm is fixedly connected to a long rotating shaft.

[0023] Preferably, a plurality of belt limiting structures distributed along the length of the frame are respectively assembled and connected to the top two sides of the frame;

[0024] The belt limiting structure includes a screw fixedly installed on the frame, an adjusting plate rotatably connected to the screw, and an abutting roller rotatably connected to the outer end of the adjusting plate.

[0025] The screw is threaded with a positioning nut that locks the positioning adjustment plate.

[0026] Preferably, both the belt unwinding mechanism and the belt winding mechanism include a winding roller, and the two ends of the winding roller are respectively rotatably connected to bearing brackets, which are fixedly installed on the frame.

[0027] A motor is connected to one end of the roller.

[0028] This utility model has the following beneficial effects:

[0029] 1. During operation, the long rotating shaft rotates, gradually raising the lifting wheel from a low position (not in contact with the belt) to lift the belt. Since the bottom of the belt rolls on the lifting wheel, normal belt transmission is not affected. During this process, the long rotating shaft-lifting wheel structure on both sides lifts the belt from both sides of the belt cutting mechanism. The increased lifting force results in greater cutting power and a more uniform cut. This structure effectively solves the technical defect of "insufficient cutting" during belt cutting.

[0030] 2. The adjustable sliding seat allows for adjustment of the belt width, thereby adjusting the position of the cutter in the belt width direction. This method enables adjustment of the cutting position to obtain belts of different widths.

[0031] 3. During the operation, before cutting, adjust the contact roller according to the belt width so that it contacts the edge of the belt. The adjustment method is as follows: loosen the positioning nut, rotate the adjusting plate, and as the adjusting plate rotates in an arc, it continuously approaches the edge of the belt. Then, the positioning nut presses and positions the roller. This method increases the stability of the belt transmission process. Furthermore, because the belt's unwinding and rewinding process is relatively short, the belt is less prone to misalignment during transmission. This method ensures a clean cut and uniform belt width after cutting. Attached Figure Description

[0042] Example 1

[0043] like Figure 1-5As shown, a belt conveyor tearing and recycling device includes a frame 1, with a belt unwinding mechanism 2 and a belt winding mechanism 3 respectively mounted and connected to the top two ends of the frame 1. Similar to existing methods, during the belt recycling process, the waste belt is pre-wound onto the belt unwinding mechanism 2 (after winding the free end of the belt several times, it is wound by a motor, and then pulled to the other free end to be wound onto the belt winding mechanism 3).

[0044] Similar to existing belt winding and unwinding structures, both the belt unwinding mechanism 2 and the belt winding mechanism 3 include a winding roller 21. Bearing supports 22 are rotatably connected to both ends of the winding roller 21. Rotary shafts rotatably connected to the bearing supports 22 are fixedly mounted at both ends of the winding roller 21, and the bearing supports are fixedly mounted on the frame 1. A motor 23 is assembled and connected to one end of the winding roller. Specifically, the output shaft of the motor 23 is fixedly mounted on the rotating shaft via a flange connection. The motor 23 is then fixed to the frame 1 via a motor bracket.

[0045] It also includes a belt cutting mechanism 4 installed on the frame 1; during the belt unwinding and rewinding process, the waste belt is cut by the belt cutting mechanism (the cutting point is close to the belt tear position, and after cutting, the width between the belt edge and the cutting position is the recyclable part).

[0046] Specifically, the belt cutting mechanism 4 includes brackets 41 fixedly installed on both sides of the top of the frame 1. A pair of support rods 43 are detachably installed between the brackets 41, and a pair of cutting blades spaced apart front to back are slidably connected between the support rods 43. That is, during the cutting process, the cutting blades are slid close to the tear position of the belt (longitudinal tearing of the belt is a common occurrence during the operation of the belt conveyor, causing the belt to tear from the center).

[0047] Specifically, the cutting component includes a sliding adjustment seat 42 slidably connected between the support rods 43, and a cutting blade 44 is fixedly connected to the bottom of the sliding adjustment seat 42; the cutting blade 44 is shaped as an oblique triangle (the oblique direction of the cutting blade 44 is the belt transmission direction, and the cutting posture has the least cutting resistance), is formed by processing steel plate, and the cutting edge is ground.

[0048] During the cutting process, the sharp part at the bottom of the cutter 44 is pressed against the belt beforehand, and as the belt is transported, the cutter 44 completely cuts the belt.

[0049] In actual operation, the sliding adjustment seat 42 is adjusted according to the required belt width, thereby adjusting the cutting position of the cutter 44 in the belt width direction. After adjustment, two pairs of adjusting nuts, respectively positioned on both sides of the sliding adjustment seat 42, are threaded onto the support rod 43. Simultaneously, locking nuts are installed at both ends of the support rod 43.

[0050] In actual operation, length scale lines can be drawn on the support rod 43 in the existing manner to facilitate the adjustment of the length position of the cutter 44 during the process, so as to determine the width of the recycled belt obtained after cutting.

[0051] Example 2

[0052] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, since the belt is made of flexible rubber material, the belt tends to bend downwards due to gravity during the cutting process, which makes it unable to fully contact the cutter 44. This leads to "virtual cutting" during the actual cutting process, and there are "continuous positions" of the cut that are not fully removed.

[0053] Therefore, in order to improve cutting efficiency and avoid incomplete cuts, belt lifting and feeding mechanisms 5 are installed on the left and right sides of the belt cutting mechanism 4 respectively (that is, the belt cutting mechanism 4 is located between the belt lifting and feeding mechanisms 5, and the belt cutting mechanisms 4 on the left and right sides are symmetrically arranged). The belt lifting and feeding mechanism 5 pushes the conveyed belt upward from the bottom of the belt, and the upward position is close to the cutting mechanism. Therefore, by pushing the belt upward, the contact force between the belt and the cutting mechanism is increased, ensuring that the cutter 44 can completely and continuously cut the belt.

[0054] Specifically, the belt conveyor feeding mechanism 5 includes a long rotating shaft 51 hinged to the lower end of the frame 1. The hinged installation method is as follows: rotating shaft brackets that rotatably connect to the long rotating shaft 51 are fixedly connected to both sides of the lower end of the frame 1. Both ends of the long rotating shaft 51 pass through the rotating shaft brackets.

[0055] Meanwhile, several lifting wheel structures are fixedly installed on the long rotating shaft 51. Specifically, the lifting wheel structure includes an lifting wheel 54, and the wheel frame of the lifting wheel 54 is fixedly connected to an lifting arm 52, which is fixedly connected to the long rotating shaft 51.

[0056] During operation, the long rotating shaft 51 is driven to rotate, and the lifting wheel 54 is gradually raised from a low position where it does not contact the belt to lift the belt. Since the bottom of the belt rolls on the lifting wheel 54, it does not affect the normal transmission of the belt.

[0057] During this process, the long rotating shafts 51 and the lifting wheels 54 on the left and right sides lift the belt from both sides of the belt cutting mechanism 4. After lifting, the cutting force increases and the cutting shearing force is greater, so the cut is more uniform.

[0058] Example 3

[0059] like Figure 1-5As shown, based on the structure of Embodiment 2, this embodiment further includes a pushing structure to drive the long rotating shaft 51 to rotate. The rotation of the long rotating shaft 51 raises the lifting wheel 54 structure to lift the tension belt. Specifically, pushing structures are installed at both the front and rear ends of the long rotating shaft 51.

[0060] The specific driving structure is as follows:

[0061] The pushing structure includes a pushing cylinder 53 hingedly mounted on the frame 1. Push seats 511 are fixedly connected to both ends of the long rotating shaft 51. A push rod 532 is fixedly connected to the piston rod of the pushing cylinder 53. A hinge sleeve hinged to the push seat 511 is fixedly connected to the push rod 532 (a fixing pin is fixedly connected to the push seat 511 and hinged to the hinge sleeve 5).

[0062] Meanwhile, a hinge plate is fixedly connected to the top of the cylinder barrel of the push cylinder 53, and a hinge bracket 531 is hinged to the hinge plate. The hinge bracket 531 is fixedly connected to the frame 1.

[0063] During operation, when the cylinder 53 is activated, it pushes the pusher seat. Since the pusher seat is fixed on the long rotating shaft 51, the long rotating shaft 51 is pushed synchronously.

[0064] In actual operation, the air circuit structure of the above-mentioned cylinder is a conventional method disclosed in the prior art. For example, the cylinder barrels of the push cylinders 53 used to push the two ends of each long rotating shaft 51 are connected to the air circuit of the cylinder in series to realize the synchronous operation of a pair of cylinders.

[0065] Those skilled in the art can learn about the specific air circuit structure and working principle of the cylinder disclosed in this utility model by consulting technical manuals and dictionaries.

[0066] Example 4

[0067] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 3, in order to prevent serious deviation of the belt during belt conveyor cutting, several belt limiting structures distributed along the length of the frame 1 are respectively assembled and connected on the front and rear sides of the top of the frame 1.

[0068] Specifically, the belt limiting structure includes a screw 63 fixedly installed on the frame 1, an adjusting plate 62 rotatably connected to the screw 63, and an abutting roller 61 rotatably connected to the outer end of the adjusting plate 62 (specifically, the abutting roller 61 is a conventional roller disclosed in the prior art, the main structure of which includes a roller, a rotating shaft 611 rotatably connected to the bottom of the roller, the rotating shaft 611 being fixed on the adjusting plate 62, and the rotatable connection method being: a bearing mounting groove is opened at the bottom of the roller, a bearing is installed inside, and the rotating shaft is rotatably connected to the bearing); a positioning nut 631 for locking the positioning adjusting plate 62 is threadedly connected to the screw 63.

[0069] During operation, before cutting, the contact roller 61 is adjusted according to the width of the belt until it contacts the edge of the belt. The adjustment method is as follows: loosen the positioning nut, rotate the adjusting plate 62. As the adjusting plate 62 rotates in an arc, it continuously approaches the edge of the belt. Then, the positioning nut 631 presses and positions it (since the belt only rubs against the rotating roller, the adjusting plate 62 can be positioned under the pressure of the positioning nut 631, and the belt-driven deviation force on the adjusting plate 62 is very small). Because the belt limiting structure is distributed along the length of the frame 1, multiple points of contact are achieved on both sides of the belt, ensuring that the belt does not deviate significantly.

[0070] This method increases the stability of belt conveyor during transmission. Furthermore, because the unwinding and rewinding process is shorter, the belt is less prone to misalignment during transmission. This method also ensures clean cuts and uniform belt width after cutting.

[0071] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
