Description

Technical Field

[0001] This utility model relates to the field of TPU waste technology, and in particular to a TPU waste shredder. Background Technology

[0002] TPU (thermoplastic polyurethane elastomer) waste refers to discarded TPU materials or products. As a plastic material with excellent performance and wide applications, the disposal of TPU waste is an important environmental issue.

[0003] The processing and production of TPU (thermoplastic polyurethane elastomer) materials generate a large amount of waste. If this waste is not properly treated, it will not only waste resources but may also pollute the environment. Therefore, how to efficiently treat and utilize this TPU waste has become an urgent problem to be solved.

[0004] Traditional TPU waste requires multiple crushing processes and constant loading and unloading, resulting in long crushing times, increased workload for workers, and inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where TPU waste needs to be crushed multiple times and fed in and out repeatedly, resulting in long crushing times, increased workload for workers, and inconvenience in use. Therefore, this invention proposes a TPU waste crusher.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A TPU waste shredder includes a shell, a circular groove on the top of the shell, and a discharge port on one side of the shell. The discharge port and the circular groove are connected to the inner cavity of the shell. A shredding component for shredding TPU waste is arranged inside the circular groove.

[0008] The same sliding plate is slidably connected between the inner walls of the two sides of the outer shell, and a discharge assembly for controlling the discharge of materials is provided below the sliding plate.

[0009] A first rack is slidably connected to one side of the outer casing, and a lifting assembly for lifting the sliding plate is provided at the bottom of the first rack.

[0010] In one possible design, the crushing assembly includes a single rotating shaft rotatably connected between the inner walls of both sides of the circular groove, with a plurality of crushing blades fixedly sleeved on the outer wall of the rotating shaft, and a servo motor fixedly connected to one side of the housing, the output shaft of the servo motor being fixedly connected to one end of the rotating shaft.

[0011] In one possible design, the discharge assembly includes two side blocks symmetrically arranged and fixedly connected to the bottom of the sliding plate. The two side blocks are rotatably connected to the same round rod. A baffle is fixedly fitted on the outer wall of the round rod. The sliding plate has multiple screen holes inside, and the baffle is used to block the screen holes.

[0012] In one possible design, the lifting assembly includes a first vertical plate fixedly connected to the bottom of a first rack, a connecting plate fixedly connected to one side of the bottom of the first vertical plate, the connecting plate being located inside the discharge port, a second vertical plate fixedly connected to one end of the connecting plate, a push plate fixedly connected to the top of the second vertical plate, and the top of the push plate abutting against the bottom of a baffle.

[0013] In one possible design, a second rack is slidably connected to one side of the outer casing, and a cover plate is fixedly connected to one side of the second rack. An arc-shaped groove is provided at the bottom of the cover plate, which works in conjunction with a circular groove. A rotating rod is fixedly connected to one side of the outer casing, and a gear is rotatably fitted on the outer wall of the rotating rod. The gear meshes with the first rack and the second rack. A handle is fixedly connected to the top of the cover plate.

[0014] In one possible design, a triangular block is fixedly connected to the bottom inner wall of the housing, and the triangular block is used in conjunction with the discharge port. Two symmetrically arranged limiting blocks are fixedly connected to one side inner wall of the housing, and the limiting blocks are used in conjunction with the sliding plate. The limiting blocks correspond to the side blocks.

[0015] In one possible design, a clearance groove is provided on the bottom inner wall of the housing, which is used in conjunction with the connecting plate.

[0016] In one possible design, the bottom four corners of the housing are all fixedly connected to support legs.

[0017] In this application, when in use, the cover plate is lifted upward by the handle, at which point a gap appears between the cover plate and the outer shell, and TPU waste can be put into the inside of the circular groove. At this point, the cover plate can be released, and due to its large weight, the cover plate moves downward under the action of gravity, covering the top of the outer shell.

[0018] At the same time, the cover plate drives the second rack to move down, the second rack drives the gear to rotate, the gear drives the first rack to move up, the first rack drives the first vertical plate to move up, the first vertical plate drives the connecting plate to move up, the connecting plate drives the second vertical plate to move up, the second vertical plate drives the push plate to move up. At this time, the push plate pushes the baffle to rotate. After the baffle rotates to a flat position, it can drive the baffle to move up.

[0019] At this point, the baffle moves the sliding plate upwards, and the sliding plate moves to the bottom of the circular groove. The servo motor is then activated, and the output shaft of the servo motor drives the rotating shaft to rotate. The rotating shaft drives the crushing blades to rotate, and the crushing blades crush the TPU waste in the enclosed space. After crushing, the cover plate is lifted again, and the baffle and sliding plate move downwards. The sliding plate falls on the limit block, and the baffle does not contact the limit block. Instead, the baffle flips downwards. After being screened through the sieve holes, the qualified material will slide down the inclined surface of the baffle and through the triangular block, and be discharged through the discharge port. Repeating the up and down movement of the cover plate allows for multiple crushing operations to ensure the crushing effect.

[0020] Beneficial effects: High-efficiency crushing: The crushing components, including a rotating shaft and multiple crushing blades, can quickly and efficiently crush TPU waste in a confined space, greatly improving processing efficiency.

[0021] Automatic discharge: The discharge and lifting components enable automatic discharge of the crushed material. After crushing, the cover plate is operated to move the sliding plate and baffle, allowing qualified material to pass through the sieve holes, slide down the inclined surface of the baffle, and be discharged through the discharge port. No manual intervention is required, improving the convenience of operation.

[0022] Energy-saving and environmentally friendly: The pulverizer of this invention is driven by a servo motor, featuring low energy consumption and low noise. Simultaneously, through pulverization and screening, TPU waste can be transformed into reusable materials, reducing resource waste and environmental pollution.

[0023] Compact Structure: The crusher of this invention features a reasonable structural design with tight fit between components, a small footprint, and is easy to install and move. Furthermore, the inclusion of clearance grooves and other structures ensures that the components do not interfere with each other during movement, improving the stability and reliability of the equipment.
