Description

Technical Field

[0001] The utility model relates to the technical field of rubber product processing, in particular to a rubber waste crushing device. Background Art

[0002] Rubber waste is the inevitable tailings produced during the production and processing of rubber products. These rubber wastes still have reuse value. For example, the rubber waste can be crushed into fine particles by a crusher, and then the finer particles or powder can be separated out by sorting equipment to make rubber powder, recycled rubber, etc.; or the rubber waste can be cold-pressed into blocks, and then crushed by a crusher, and then screened to obtain rubber particles, recycled rubber, etc.; or the rubber waste can be dissolved in chemicals, and then filtered, evaporated and other process steps to obtain rubber oil, recycled rubber, etc.

[0003] Among them, in the process of crushing and recycling rubber waste, a rubber crusher is needed, such as a rubber crusher disclosed in patent CN220841053U. When in use, the rubber material is poured from the top of the crushing box into the space between the two crushing rollers, and the rubber material is crushed by the two crushing rollers, and then the crushed material is shredded by the cutting blade. However, since the rubber material is highly tough and easy to deform, and the crushing rollers are crushed by extrusion, part of the rubber is only deformed during the extrusion process, but not completely broken. Therefore, after crushing, some of the rubber material will still have the phenomenon of "broken ligaments". Even if the cutting blade is used for cutting later, it cannot be guaranteed that all the rubber material is cut off. Therefore, the crushing effect is general and needs to be improved.

[0004] In order to solve the above problems, the utility model provides a rubber waste crushing device, including a box body, a cover body, a driving motor, a cutting blade, a crushing groove, an opening and closing mechanism and a collecting barrel, the cover body is arranged on the top of the box body and one end of the two is rotatably connected by a first hinge, the driving motor is arranged in the cover body, the cutting blade is arranged below the cover body and is connected to the driving motor through a transmission shaft, the crushing groove is arranged between the box body and the cover body, the collecting barrel is arranged in the box body and is located below the crushing groove, and the opening and closing mechanism is arranged on both sides of the dropping port of the crushing groove.

[0005] Furthermore, the opening and closing mechanism includes a rodless cylinder, a connecting arm and a material baffle plate. The rodless cylinder is horizontally arranged on one side of the crushing trough, and the material baffle plate can be movably arranged at the drop-out port of the crushing trough. The rodless cylinder is transmission-connected to the material baffle plate through the connecting arm.

[0006] Furthermore, the crushing groove is an inverted frustum-shaped structure that is wide at the top and narrow at the bottom.

[0007] Furthermore, two groups of cutting blades are symmetrically arranged along the axial direction of the transmission shaft, and the cutting blades on the upper side are longer than the cutting blades on the lower side.

[0012] Furthermore, a handle is provided on the side wall of the cover body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The rubber waste crushing device of the utility model drives the cutting blade to rotate at a high speed through a driving motor to crush the rubber waste in the crushing groove. After the crushing is completed, the drop-out port is opened through the opening and closing mechanism to allow the rubber fragments to enter the collecting barrel below. The high-speed rotation of the cutting blade can fully crush the rubber waste, thereby effectively improving the crushing efficiency of the rubber waste. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, a rubber waste crushing device in this embodiment includes a box body 1, a cover body 2, a driving motor 3, a cutting blade 4, a crushing groove 5, an opening and closing mechanism 6 and a collecting barrel 7. The cover body 2 is arranged on the top of the box body 1 and one end of the two are rotatably connected by a first hinge 8. A handle 9 is also provided on the side wall of the cover body 2 to facilitate opening and closing the cover body 2; a box door 10 is provided on the outer wall of the box body 1, one side of the box door 10 is rotatably connected to the box body 1 through a second hinge 11, and the other side of the box door 10 is connected to the box body 1 through a hasp lock 12.

[0024] A sealing plate 13 is provided at the bottom of the cover body 2. When the cover body 2 is buckled, the sealing plate 13 is buckled on the feed port of the crushing tank 5 to seal the feed port of the crushing tank 5 and prevent the material from splashing out during the crushing process.

[0025] The cover 2 and the sealing plate 13 are both made of transparent plastic, such as PC, PP, acrylic, etc., so as to facilitate observation of the crushing of the rubber waste.

[0026] The driving motor 3 is arranged in the cover body 2, the cutting blade 4 is arranged below the cover body 2 and is connected to the driving motor 3 through the transmission shaft 14, two groups of cutting blades 4 are symmetrically arranged along the axial direction of the transmission shaft 14, and the upper cutting blade 4 is longer than the lower cutting blade 4; the crushing groove 5 is arranged between the box body 1 and the cover body 2, and the crushing groove 5 is an inverted cone-shaped structure that is wide at the top and narrow at the bottom.

[0027] The collecting barrel 7 is arranged in the box body 1 and is located below the crushing trough 5 , and the opening and closing mechanism 6 is arranged on both sides of the material dropping opening of the crushing trough 5 .

[0028] like Figure 4 As shown, the box body 1 and the other side of the cover body 2 are attracted by two magnets 15 with opposite polarities to fix the position of the cover body 2; when opening, the cover body 2 can be lifted up with a little force.

[0029] like Figure 5 As shown, the opening and closing mechanism 6 includes a rodless cylinder 61, a connecting arm 62 and a material baffle plate 63. The rodless cylinder 61 is horizontally arranged on one side of the crushing trough 5, and the material baffle plate 63 is movably arranged at the drop-out port of the crushing trough 5.
