Description

Technical Field

[0001] The utility model relates to the technical field of crushing, in particular to a polyvinyl chloride plate crushing device with a protective structure. Background Art

[0002] The natural color of polyvinyl chloride (PVC) is slightly yellow and translucent, shiny, and more transparent than polyethylene and polypropylene, but less transparent than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than low-density polyethylene, but lower than polypropylene, and whitening will occur at the bends. Common products: plates, pipes, soles, toys, doors and windows, wire sheaths, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene. PVC plates can be recycled after being crushed.

[0003] The prior art, for example, a utility model of a gypsum board and PVC board crushing device, with authorization announcement number CN217431800U, puts the board in and then crushes it, but because the upper opening is not blocked, it is easy to cause the broken pieces to splash and cause accidental injuries to the staff.

[0004] At present, there is still a lack of a device that can easily break the polyvinyl chloride sheets after they are placed and avoid the broken pieces from splashing.

[0005] Therefore, in view of the above problems, a polyvinyl chloride sheet material crushing device with a protective structure is proposed to solve the above problems. Utility Model Content

[0007] The technical solution of the utility model to solve the technical problem is as follows: the utility model provides a polyvinyl chloride sheet crushing device with a protective structure, including a cone bottom box, which is hollow inside, and the cone bottom box is provided with a sink; symmetrical rollers are arranged in the cone bottom box, the central axes of the symmetrical rollers are respectively connected to the cone bottom box with bearings, and the symmetrical rollers are respectively connected to a group of annular cutting blades, and the two groups of annular cutting blades are staggered; the bottom of the arc top square box is arranged in the sink, the arc top square box is connected to the cone bottom box, and the arc top square box is provided with a circular groove, an inlet and an outlet, and the inlet and the outlet are respectively connected to the circular groove; the installation shaft is arranged in the circular groove, the bearing is connected to the arc top square box, and the installation shaft is fixedly connected to a group of flaps, and the flaps match the circular groove. By arranging the flaps in the circular groove, it is convenient to realize the sealed transportation of polyvinyl chloride sheets and avoid the splashing of broken pieces.

[0008] As an optimization, the central axes of the symmetrical rollers are respectively connected to gears, and the symmetrical gears mesh with each other. By adopting the meshing of gears, the two sets of annular cutting blades can rotate in opposite directions, which facilitates the cutting of polyvinyl chloride sheets.

[0009] As an optimization, the arc top square box is connected to the motor bracket, the motor bracket is connected to the motor, and the output shaft of the motor is connected to the central axis of one of the rollers. By adopting the motor drive, the input and cutting of the polyvinyl chloride sheet can be easily realized.

[0010] As an optimization, the mounting shaft is fixedly connected to the large gear, the arc top square box bearing is connected to the central axis of the small gear, the small gear meshes with the large gear, the central axis of the other roller and the central axis of the small gear are respectively connected to the synchronous wheel, and the two ends of the synchronous belt surround the corresponding synchronous wheel. By adopting the synchronous belt mechanism, the annular cutting blade and the flap can be synchronously moved.

[0011] As an optimization, the cone bottom box is provided with a discharge port. By providing the discharge port, it is convenient to collect the crushed fragments.

[0012] As an optimization, the four corners of the cone bottom box are respectively connected to support legs. By setting the support legs, the support of the device is achieved.

[0013] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0014] (1) The device is provided with a flap to facilitate the placement of the polyvinyl chloride sheet into the annular cutting blade component area. The flap component area isolates the entrance from the cone bottom box to prevent the broken pieces from splashing.

[0015] (2) The device is provided with a sinking groove so that when the flap is at the lowest end, it is close to the annular cutting blade. When the polyvinyl chloride plate contacts the annular cutting blade, the lower end of the flap contacts the upper end of the polyvinyl chloride plate, giving the polyvinyl chloride plate a certain pressure, which facilitates cutting by the annular cutting blade.

[0016] (3) The device is driven by a motor, gear meshing and a synchronous belt mechanism to achieve the movement of the flap and the annular cutting blade. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
