Description

Technical Field

[0001] This utility model relates to the field of tire processing, and in particular to a tire cutting machine. Background Technology

[0002] Achieving low energy consumption, high production efficiency, low manufacturing cost, and convenient and low maintenance costs for waste tire processing equipment is a common goal pursued by the economy and society. Through years of effort, the field of waste tire processing technology has developed a variety of processing technologies and related processes, each with its own characteristics. However, currently, in the process of crushing waste tire rubber blocks into rubber granules and powder, many problems are faced, namely, complex equipment structure, large size, high energy consumption, high noise, long manufacturing cycle, high manufacturing and maintenance costs, and low safety.

[0003] In the waste tire processing industry, there are generally two processes for whole tire dismantling. One process uses a tire shredder, a crucial piece of equipment in waste tire processing. These shredders typically have an installed power of around 64kW, and the maintenance and replacement costs of their blades are very high. Replacing or repairing blades requires disassembling the machine body, bearing housings, main shaft, and other components, which is time-consuming, labor-intensive, and impacts production efficiency, increases maintenance costs, and presents considerable difficulty for non-technical personnel. The other process is: rim cutting - slitting - block cutting, commonly known as the "small three-piece" process. This process has a significant safety hazard: the slitting machine can easily cut off the operator's hand or fingers when the operator becomes numb from prolonged work. This safety hazard is a major concern and source of confusion for everyone in the industry, leading to the development of tire cutting machines. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A tire cutting machine includes a support frame. A first lifting frame is movably mounted at the bottom end of one side of the support frame. A first rotating shaft is laterally rolled at the top end of the first lifting frame. Lifting plates are laterally mounted on both the front and rear sides of the top end of the first lifting frame, and the lifting plates and the first lifting frame move in the same direction. A first motor is vertically mounted at the top end of one side of the support frame, and a first drive shaft is driven at the bottom end of the first motor. The first drive shaft is vertically located on the side of the support frame and is parallel to the first lifting frame. The bottom end of the first drive shaft is horizontally rolled... A first cutting wheel is provided, which causes the first motor to drive the first drive shaft to rotate, thereby driving the first cutting wheel to rotate. A second lifting frame is movably provided at the bottom of the other side of the support frame, and a second rotating shaft is laterally rolled at the top of the second lifting frame, and the second rotating shaft and the second lifting frame move in the same direction. A second motor is laterally provided at the top of the other side of the support frame, and a second drive shaft is driven and connected to one side of the second motor. A second cutting wheel is vertically provided at the other end of the second drive shaft, and the second drive shaft and the second cutting wheel move coaxially.

[0006] Preferably, the lifting plate is provided with a third traction roller, and the third traction roller is located laterally on both sides of the lifting plate. The third traction roller rolls on both sides of the lifting plate, thereby rotating in the same direction with the first rotating shaft through the third traction roller.

[0007] Preferably, the first lifting frame is provided with second traction rollers, and the second traction rollers are all located laterally on both sides of the first lifting frame, and the second traction rollers roll on the side of the first lifting frame.

[0008] Preferably, a lifting cylinder is provided between the second lifting frame and the support frame, and the lifting cylinder is obliquely located at the bottom end of the support frame. The lifting cylinder is driven to the second lifting frame, thereby driving the second lifting frame to swing up and down on the other side of the support frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the first lifting frame is lowered from one side of the support frame, the tire is placed laterally on the first lifting frame and supported by the lifting plate. At this time, the first lifting frame is lifted upward and drives the tire to move upward, and the tire gradually changes from a laterally placed state to a vertically inclined state. At this time, the first rotating shaft contacts the inner wall of the tire, and the first cutting wheel abuts against the outer edge of the tire. At this time, the first motor drives the first cutting wheel to rotate, and the first cutting wheel cuts through the edge of the tire. The first rotating shaft rolls and drives the tire to move in a circular motion around the first lifting frame. The rotating first cutting wheel gradually cuts the edge of the circumferentially rotating tire, thereby cutting and separating the edge of the tire. When the first rotating shaft stops rotating and the first lifting frame moves downward again, the tire, whose edges have been cut and separated, gradually changes from a vertical to a horizontal position. At this time, the operator places the tire, whose edges have been cut and separated, horizontally on the second lifting frame. The second lifting frame then lifts upward, along with the tire, so that when the second lifting frame is vertically positioned on the side of the support frame, the tire changes from a horizontal to a vertical position. The third traction roller contacts the inner wall of the tire, and the second cutting wheel abuts against the outer edge of the tire. At this time, the third traction roller moves the tire towards the side of the support frame, and the second motor simultaneously drives the second cutting wheel to cut the tire, thereby cutting the tire into segments and dividing it into multiple pieces.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2In this embodiment of the utility model, the tire cutting machine includes a support frame 1. A first lifting frame 2 is movably arranged at the bottom end of one side of the support frame 1, and a first rotating shaft 6 is laterally rolled at the top end of the first lifting frame 2. Lifting plates 7 are laterally arranged on both the front and rear sides of the top end of the first lifting frame 2, and the lifting plates 7 and the first lifting frame 2 move in the same direction. A first motor 3 is vertically arranged at the top end of one side of the support frame 1, and a first drive shaft 4 is driven at the bottom end of the first motor 3. The first drive shaft 4 is vertically located on the side of the support frame 1, and the first drive shaft 4 is parallel to the first lifting frame 2. A first cutting wheel 5 is laterally arranged at the bottom end of the first drive shaft 4, thereby causing the first motor 3 to drive... When the first drive shaft 4 rotates, it drives the first cutting wheel 5 to rotate. A second lifting frame 10 is movably installed at the bottom of the other side of the support frame 1, and a second rotating shaft 12 is laterally rolled at the top of the second lifting frame 10. The second rotating shaft 12 and the second lifting frame 10 move in the same direction. A second motor 13 is laterally installed at the top of the other side of the support frame 1, and a second drive shaft 14 is driven and connected to one side of the second motor 13. A second cutting wheel 15 is vertically installed at the other end of the second drive shaft 14, and the second drive shaft 14 and the second cutting wheel 15 move coaxially. Therefore, when the first lifting frame 2 is moved down from one side of the support frame 1, the tire is placed laterally on the first lifting frame 2 and lifted. Plate 7 supports the tire. At this time, the first lifting frame 2 lifts upwards, causing the tire to move upwards and gradually change from a horizontal to a vertically angled position. The first rotating shaft 6 contacts the inner wall of the tire, and the first cutting wheel 5 abuts against the outer edge of the tire. The first motor 3 drives the first cutting wheel 5 to rotate, cutting through the tire edge. The first rotating shaft 6 rolls, causing the tire to rotate in a circle around the first lifting frame 2. The rotating first cutting wheel 5 gradually cuts the edge of the rotating tire, thus separating the tire edge. At this point, the first rotating shaft 6 stops rotating, and the first lifting frame 2 moves downwards again, allowing the edge to be cut... As the separated tires gradually change from a vertical to a horizontal position, the operator places the edge-cut tire horizontally onto the second lifting frame 10. The second lifting frame 10 is then raised upwards, lifting the tire upwards as well. When the second lifting frame 10 is vertically positioned on the side of the support frame 1, the tire changes from a horizontal to a vertical position. The third traction roller 12 contacts the inner wall of the tire, and the second cutting wheel 15 abuts against the outer edge of the tire. At this point, the third traction roller 12 moves the tire toward the side of the support frame 1, and the second motor 13 simultaneously drives the second cutting wheel 15 to cut the tire, thereby segmenting the tire into multiple pieces.

[0017] The lifting plate 7 is equipped with a third traction roller 16, and the third traction roller 16 is located laterally on both sides of the lifting plate 7. The third traction roller 16 rolls on both sides of the lifting plate 7, and thus rotates in the same direction with the first rotating shaft 6. This allows the first rotating shaft 6 to drive the tire to make circular motion on the first lifting frame 2, and the third traction roller 16 provides transmission traction, making the tire's circular motion on the lifting plate 7 more stable.

[0018] The first lifting frame 2 is equipped with a second traction roller 9, and the second traction roller 9 is located laterally on both sides of the first lifting frame 2. The second traction roller 9 rolls on the side of the first lifting frame 2, thereby supporting and tractioning the tire when the tire is vertically and obliquely positioned on the first lifting frame 2 through the second traction roller 9.

[0019] A lifting cylinder 11 is provided between the second lifting frame 10 and the support frame, and the lifting cylinder 11 is located obliquely at the bottom end of the support frame 1. The lifting cylinder 11 is connected to the second lifting frame 10 for driving, thereby driving the second lifting frame 10 to swing up and down on the other side of the support frame 1 through the lifting cylinder 11.

[0020] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
