Description

Technical Field

[0001] The utility model relates to the technical field of polyvinyl chloride waste treatment, in particular to a polyvinyl chloride pipe waste crushing and recovery device. Background Art

[0002] Polyvinyl chloride (PVC) is a polymer formed by the polymerization of vinyl chloride monomer in the presence of initiators such as peroxides and azo compounds, or by the free radical polymerization mechanism under the action of light or heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. During the production process of existing polyvinyl chloride pipes, due to manual or machine reasons, the size of the finished product may be inaccurate or the surface may be damaged, resulting in waste. These wastes need to be crushed and recycled so that the recycled waste can be reprocessed into finished products.

[0003] The prior art, such as the utility model of a PPR pipe production waste crushing and recycling device, authorization announcement number CN217943942U, realizes the crushing of waste. At present, there is still a lack of a device that can cut the waste twice and between the two cuts, realize the auxiliary downward push of the waste to accelerate the crushing of the waste.

[0004] Therefore, in view of the above problems, a waste crushing and recycling device for polyvinyl chloride pipes is proposed to solve the above problems. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the utility model develops a waste crushing and recycling device for polyvinyl chloride pipes. The utility model can cut the waste twice and, between the two cuts, assist in pushing the waste downward to accelerate the crushing of the waste.

[0006] The technical solution of the utility model to solve the technical problem is as follows: the utility model provides a waste crushing and recycling device for polyvinyl chloride pipes, including a lower cover, the upper side of the lower cover is fixedly connected to the lower end of the intermediate pipe, and the upper end of the intermediate pipe is fixedly connected to the conical cover; symmetrical rollers are arranged in the lower cover, the central axes of the symmetrical rollers are respectively connected to the lower cover by bearings, and the symmetrical rollers are respectively fixedly connected to a group of evenly distributed annular blades, and the two groups of annular blades are staggered; symmetrical gears are respectively arranged on one side of the lower cover, the symmetrical gears are respectively connected to the central axes of the corresponding rollers, and the symmetrical gears are meshed with each other; a motor is arranged on one side of the gear, the output shaft of the motor is fixedly connected to the central axis of one of the rollers, the motor is connected to the motor bracket, and the motor bracket is connected to the conical cover. The waste is crushed by using annular blades.

[0007] As an optimization, the conical cover is provided with a card slot, a slider is nested in the card slot, the slider is connected to the slide plate, and the slide plate is connected to the plug plate. The plug plate reciprocates along the height direction to play the role of feeding downward, driving the waste to move downward, and speeding up the processing speed of the waste.

[0008] As an optimization, the slide plate matches the card slot. The slide plate moves up and down reciprocatingly, always shielding the card slot to prevent waste from escaping from the conical cover from the card slot.

[0009] As an optimization, the central axes of the symmetrical rollers are respectively connected to the center of the turntable, the edges of the symmetrical turntables are respectively connected to round blocks, the sliders are connected to the vertical rods, the vertical rods are connected to the horizontal grooves, and the symmetrical round blocks are respectively arranged in the horizontal grooves. The device provides power for the movement of the plug board, etc. by arranging the round blocks in the horizontal grooves.

[0010] As an optimization, the plug plate is fixedly connected to a set of cutters. By setting the cutters, the cutters can cut the waste and at the same time, feed the waste downward, drive the waste downward, and speed up the processing of the waste.

[0011] As an optimization, the vertical rod is connected to the L frame, the L frame is connected to the rack, the intermediate tube bearing is connected to the central axis of the flap, the central axis of the flap is fixedly connected to the pinion, and the rack meshes with the pinion. By adopting the meshing of the gear and rack, the flap movement is realized. When the cutter moves downward to the lowest end, the flap is horizontal, and the gap between the two is very small, so that the cutter can cut the waste material for the first time.

[0012] 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:

[0013] (1) The device realizes two cuts on the waste by setting a cutter and an annular blade, and the cutting directions are perpendicular to each other, which facilitates the crushing and recycling of the waste.

[0014] (2) The device is provided with a cutter, which not only cuts the waste but also plays the role of feeding the waste downward, driving the waste to move downward and speeding up the waste processing speed.

[0015] (3) This device uses only one motor, gear meshing and rack-and-pinion meshing to achieve two cuts and assist in pushing the waste downward between the two cuts, simplifying the system structure and making the operation simple. BRIEF DESCRIPTION OF THE DRAWINGS
