The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, which are not repeated herein, but the present invention is not limited to the following embodiments.

Referring to fig. 1, the crusher of the present invention includes a cabinet 1, a support frame 2, and a driving member 3. Wherein, machine case 1 and driving piece 3 all support on supporting frame 2, and movable tooth 4, fixed tooth 5 and pivot 6 that play the function of crushing material all set up inside machine case 1, can increase the leakproofness of equipment to a certain extent. Fixed tooth 5 then through the fixed setting of welded mode interval on quick-witted case 1 inner wall, according to the utility model discloses a design, the upper surface of fixed tooth 5 is equipped with the holding tank 51 that the formula that tapers down extends. In this way, the stalk crushing process can be controlled in the holding tank 51, thereby effectively preventing the stalk from being splashed out.

Referring to fig. 2, the movable teeth 4 of the present invention are disposed on the rotating shaft 6 at regular intervals (sleeved), the rotating shaft 6 is rotatably disposed in the case 1, and one end of the rotating shaft is connected to the driving member 3. In the present embodiment, the fixed teeth 5 are staggered with the movable teeth 4, i.e. each fixed tooth 5 is located between two movable teeth 4, so that during the rotation of the rotating shaft 6, the two teeth can form a staggered shear to crush the material stalks. As shown in fig. 2, the receiving groove 51 of the present embodiment is a triangular groove (or dovetail groove) having two inclined groove walls, so that the receiving groove 51 forms an inverted triangle with a downward tip. Thus, during the rotation of the movable tooth 4, the tooth surface of the movable tooth presses the material shank on the groove wall of the accommodating groove 51 on the side close to the rotating shaft 6. At the moment when the material handle is crushed, the crushed objects are bounced off by the side groove wall, and the groove wall at the other side can form a barrier to the crushed objects, so that the function of controlling the crushing process of the material handle in the accommodating groove 51 is realized. Of course, the shape of the receiving groove 51 may be an arc-shaped groove or a trapezoid-shaped groove, so long as the width of the groove is ensured to be gradually reduced from top to bottom. In the present embodiment, the movable teeth 4 are formed in a circular plate-like structure, and spaced apart grooves 41 are provided at intervals in the circumferential direction, thereby forming teeth. Based on the above concept, the groove wall of the spacing groove 41 also forms the tooth surface of the tooth, and the groove can also be a triangular through groove consisting of two inclined groove walls. Of course, in other embodiments, the teeth may be formed by directly projecting the main body of the movable teeth 4. The movable teeth 4 designed according to the structure are shaped like a windmill, namely, certain wind power can be generated after the movable teeth rotate, so that dust generated by crushing is absorbed into the case 1 as much as possible, the dust is prevented from flying out of a feeding hole, and the dustproof function is further enhanced.

Referring to fig. 3, in the present invention, the casing 1 is a hollow rectangular structure, and the adjacent left side and bottom are respectively provided with a feeding channel 8 and a discharging channel 9 communicated to the inside of the casing 1. In the installed state shown in fig. 3, the feeding channel 8 is parallel to the horizontal plane, and has better sealing performance relative to the top opening, i.e. the material can be further prevented from splashing out of the cabinet 1; the discharging channel 9 is vertical to the horizontal plane, so that the crushed objects after the material handle is crushed can flow out of the device to the material collecting barrel by means of the gravity of the crushed objects. Namely, the utility model discloses a two passageways of feeding and the ejection of compact of crusher are mutually perpendicular. As can be seen from fig. 1, the feeding channel 8 gradually expands towards a direction away from the cabinet 1 to form a wide-mouth structure (which can also be understood as gradually shrinking towards the feeding direction), so that the feeding port of the cabinet 1 is in a bell-mouth shape. The opening of the feeding channel 8 is convenient for receiving a material handle output by a discharge port of a lens shearing machine, so that the equipment and the lens shearing machine can be mutually independent, the equipment vibration is avoided from causing harmful interference to the work of the lens shearing machine, and the work of the crusher is prevented from influencing the appearance of the lens. Meanwhile, the wide-mouth structure can also prevent the materials from flying out of the equipment in the process of cutting the materials into the clinker of the crusher, thereby increasing the sealing property of the equipment. The discharge channel 9 is a rectangular channel, and the size of the discharge channel is suitable for the size of the material collecting barrel. In the installed state, the shaft 6 is parallel to the direction of the feed channel 8 (i.e. from left to right in fig. 3), which is also understood to mean that the plane of the feed opening is parallel to the plane of rotation of the shaft 6. In this way, the turning plane in the process of crushing the material handle is basically vertical to the feeding direction, so that the material is further prevented from splashing out of the equipment. Further, the upper edge of the movable tooth 4 in the mounted state is also lower than the lower edge of the feed channel 8. So for the process of rolling the crushed aggregates handle is all carried out below the feed inlet of the case 1, thereby further improving the dustproof effect.

With continued reference to fig. 3, the support frame 2 of the present invention includes upper and lower panels 21, 22 and four legs 23 disposed between the upper and lower panels 21, 22 to form a support. The cabinet 1 and the driving member 3 (see fig. 1) are supported on the upper panel 21. Accordingly, the top panel 21 should also be correspondingly open to allow the outlet channel 9 of the cabinet 1 to pass through. Of course, if the machine box 1 is not provided with the discharging channel 9, the opening on the upper panel 21 can be regarded as the discharging port of the equipment, and the opening is also perpendicular to the rotating plane of the rotating shaft 6 and basically opposite to the set of the movable teeth 4, the fixed teeth 5 and the rotating shaft 6 for crushing. In addition, in order to provide safety protection for the case 1 and the driving member 3 during operation, the utility model discloses two protection plates 10 arranged oppositely are still set up on the top panel 21 of the supporting frame 2, and the case 1 and the driving member 3 are located between these two protection plates 10. After installation, as shown in fig. 3, the left side shield plate 10 is located just below the feed passage 8, and the other side shield plate 10 is located opposite thereto. The utility model discloses in, guard plate 10 is hollow cuboid structure, and it establishes to hollow purpose can hold the drive mechanism that driving piece 3 and pivot 6 are connected. Therefore, the protection plate 10 can also be called as a protection cover, the installation form of the protection plate can be detachably arranged on the upper panel 21, the specific disassembly form is not limited too much, such as plugging, bolt connection and the like, and the purpose is to facilitate the disassembly and assembly of the equipment. In the present embodiment, the driving member 3 is a motor, and a conventional alternating current of 220V is applied as a power. And, a belt transmission mechanism is provided in the shielding plate 10 located at the left side in fig. 3, thereby indirectly connecting the motor to the left end of the rotation shaft 6 to transmit the power of the motor to the rotation shaft 6. According to the utility model discloses an above-mentioned structure can know, the guard plate 10 of the left and right sides is hollow structure, therefore drive mechanism is located in the guard plate 10 of which one side all can, and motor output is all towards arbitrary side promptly to be convenient for the design and the equipment of equipment. The lower panel 22 of the support frame 2 can then receive the receiving chute and thus the crushed material that has leaked down the discharge channel 9.

Referring to fig. 4, the two ends of the rotating shaft 6 of the present invention are respectively provided with a bearing 7, and the rotating shaft 6 is rotatably disposed in the case 1 through the bearings 7. Therefore, compared with the mode that the rotating shaft 6 is directly connected with the box wall of the case 1, the mode has smaller friction resistance and can also reduce vibration so as to further reduce the dust raising phenomenon and limit the harm of the dust raising. And, the device noise can also be effectively reduced. As can be seen from fig. 4, the axis of the rotating shaft 6 of the present invention is higher than the upper surface of the fixed teeth 5. Therefore, the position of the fixed teeth 5 is lower, so that the position of the material handle is as far as possible downward when the material handle is crushed to be far away from the feeding hole, and the material is further prevented from splashing from the feeding hole.

According to the above setting the utility model discloses a crusher places crusher department at the shearing machine feed opening when using. Firstly, the motor is powered on, and the rotating shaft 6 and the movable teeth 4 are driven by the motor to synchronously rotate. Lens material handles in the lens shearing machine fall into a feeding hole of the crusher, then flow to the movable teeth 4 and the fixed teeth 5 through a feeding channel 8, and are crushed under the combined action of the movable teeth 4 and the fixed teeth 5. Crushed aggregates after the material handle is crushed flow out through the discharging channel 9 by means of self gravity and fall into the material collecting barrel to complete the crushed aggregates. In conclusion, the external crusher is suitable for various sheet shearing machines, and has the advantages of simple structure, simple and reasonable design and low cost. The conditions of vibration, material handle splashing and dust raising can not be caused in the process of crushing the material handle, and the influence on the appearance quality of the lens in a dust-free workshop can be reduced. And the device is independent from the film cutting machine, has no adverse interference due to no interaction with the film cutting machine, and does not need to replace the old film cutting machine or carry out other improvements on the old film cutting machine.

The above description is only one embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
