Description

Technical Field

[0001] The invention belongs to the technical field of pulverizers, and in particular relates to a single-shaft toothed knife intelligent pulverizer. Background Art

[0002] During machining, a large amount of chips will be generated. In order to better recycle these chips, the chips need to be crushed for subsequent processing. The existing double-shaft toothed cutter crushers on the market force the chips to be drawn in by the counter-rotating double shafts and then crushed by shearing, squeezing, tearing, etc. However, when there are a large amount of chips in the hopper, this feeding method is likely to cause the equipment to overload and jam; in addition, the chips may be mixed with large pieces of hard metal materials, and crushing these pieces will cause collision damage to parts or mechanisms such as toothed cutters. Therefore, it is very important to feed smoothly and prevent large pieces of material from entering the crushing mechanism. Summary of the invention

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0026] AsFigures 1 to 2 As shown in the figure, it is a structural diagram of a single-axis tooth cutter intelligent crusher provided by an embodiment of the present invention, including:

[0027] A hopper 2, on which a feeding mechanism 1 is provided;

[0028] A crushing mechanism, connected to the hopper 2;

[0029] A material jamming buffer mechanism, installed on the frame 13 and connected to the crushing mechanism, used to buffer the collision impact during material jamming, and drive the crushing mechanism to reverse and push the material or stop the machine.

[0030] In an embodiment of the present invention, aiming at the deficiencies in the prior art, the single-axis tooth cutter intelligent crusher is provided with a crushing mechanism and a material jamming buffer mechanism, which has the advantages of progressive feeding, screening of large pieces of materials, and stable and uniform feeding of chip materials. Through the material jamming buffer mechanism, the collision impact can be buffered when the equipment jams, and the switch can be triggered to make the motor of the crushing mechanism reverse and push the material or stop the operation of the equipment, effectively preventing damage to related parts or equipment such as tooth cutters, transmission gears, and reduction motors;

[0031] The chip materials generated by machining enter the hopper 2, and the feeding mechanism 1 at the upper end of the hopper 2 (the specific structure of the feeding mechanism 1 can be selected according to actual needs as long as it can realize feeding) pushes the chip materials to the bottom of the hopper 2, and then the chip materials are crushed by the bottom crushing mechanism and fall below the equipment.

[0032] As Figures 3 to 5 shown, as a preferred embodiment of the present invention, the crushing mechanism includes a rotating tooth 4 and a fixed tooth 5, and a gap is formed between the cutting edges of the rotating tooth 4 and the fixed tooth 5.

[0033] Multiple rotating teeth 4 and fixed teeth 5 are arranged in an uneven and spaced-apart shearing structure, which can crush the chip materials generated in machining and facilitate subsequent processing. The specific forms of the crushing mechanism can be as follows:

[0034] As Figure 3 shown, as another preferred embodiment of the present invention, the fixed tooth 5 is fixedly installed and horizontally arranged, and the blade body of the fixed tooth 5 points to the axis of the rotating tooth 4;

[0035] As Figure 5 shown, as a preferred embodiment of the present invention, the crushing mechanism further includes a connecting rod 11, and the connecting rod 11 is connected to the fixed tooth 5 through a rotating shaft 12, used to drive the connecting rod 11 to rotate and swing along the rotating shaft 12 to disturb the state of the chip materials;

[0036] As Figure 4 shown, as a preferred embodiment of the present invention, the fixed tooth 5 is fixedly installed, and the pointing direction of the blade body of the fixed tooth 5 intersects with the axis of the rotating tooth 4;

[0037] As Figure 4 shown, as a preferred embodiment of the present invention, the fixed tooth 5 is movably installed, and the blade direction of the fixed tooth 5 intersects with the axis of the rotating tooth 4.

[0038] The specific structures of the rotating tooth 4 and the fixed tooth 5 in the crushing mechanism can be that the fixed tooth 5 is fixed and horizontally arranged, the blade direction passes through the axis of the rotating tooth 4, and a certain gap is formed between the blade of the rotating tooth 4 and the blade of the fixed tooth 5; it can also be that the blade direction of the fixed tooth 5 forms a certain intersection angle with the rotating tooth 4. At this time, the fixed tooth 5 can be in a fixed state or can rotate and swing within a certain angle range. A certain gap is formed between the blade of the rotating tooth 4 and the blade of the fixed tooth 5; in addition, the connecting rod 11 can be movably connected through the rotating shaft 12, and the connecting rod 11 can rotate and swing within a certain angle range along the rotating shaft 12 to disturb the state of the chips, making it easier for the chips to move towards the bottom of the hopper 2 for easy crushing;

[0039] The crushing mechanism is driven by a driving motor (which belongs to the conventional technical content in the field, and its specific structure and principle will not be elaborated here).

[0040] As Figures 2 to 4 、 Figure 6 shown, as a preferred embodiment of the present invention, the material clamping and buffering mechanism includes:

[0041] A speed reducer 3, connected to the crushing mechanism, and the speed reducer 3 is installed on the bottom plate 8;

[0042] A first support seat 6 and a second support seat 7, installed on the frame 13, are respectively supported by a first spring 9 and a second spring 10, and the bottom plate 8 is installed on the first support seat 6 and the second support seat 7.

[0043] When a large hard material enters the hopper, due to the small gap between the rotating tooth 4 and the fixed tooth 5, the large material block cannot be rotated into the crushing space. Therefore, the large-volume hard material block will be excluded outside the tooth cutter, while the small material block or filamentous chips are rotated into the crushing by the rotating tooth 4. Once the hard material block moves between the rotating tooth 4 and the fixed tooth 5 and the two teeth cannot cut the material block, the rotating tooth 4 will be stuck and unable to continue rotating, forcing the entire speed reducer 3 to rotate in the opposite direction. The impact on the equipment during the crushing of the hard material block is buffered by the first spring 9 and the second spring 10 on the first support seat 6 and the second support seat 7. When the speed reducer 3 rotates to the limit position multiple times, the detection system (not shown in the figure, which belongs to the conventional technical content in the field, and its specific structure and principle will not be elaborated here) can make a judgment and stop the operation of the equipment to protect the equipment.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
