Detailed Embodiments

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0030] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] To facilitate the understanding of the technical solution of the present application, the shearing method of the existing shearing device is described herein: The existing shearing device usually uses a motor to cooperate with a lead screw to drive the cutter to move, and then cuts the material with the cutter. However, the shearing force driven by the motor is small, so for materials that are not easy to cut, it is not suitable to use the motor-driven method for shearing.

[0032] As Figures 1 to 3 shown, the shearing device provided by an embodiment of the present application includes a frame and a feeding mechanism 120 and a shearing mechanism 130 arranged on the frame. The frame includes a shearing table 111. The feeding mechanism 120 can push the high-purity material into the shearing table 111, and the shearing mechanism 130 is arranged corresponding to the shearing table 111 for shearing the high-purity material.

[0033] Further, the feeding mechanism 120 includes a pusher 121 that can reciprocate. During the movement of the pusher 121, it can push the high-purity material into the shearing table 111. The shearing structure includes a hydraulic driving member 131 and a cutter 132. The hydraulic driving member 131 is arranged on the shearing table 111 and is connected to the cutter 132 to drive the cutter 132 to reciprocate. The cutter 132 is arranged corresponding to the shearing table 111 for shearing the high-purity material at the shearing table 111.

[0034] With the above-mentioned shearing device, the pusher 121 pushes the high-purity material into the shearing table 111, and the hydraulic driving member 131 drives the cutter 132 to shear the high-purity material at the shearing table 111. Since this shearing device uses hydraulic drive, the shearing force is large, and it can shear high-purity materials that are difficult to cut, improving the applicable range of this shearing device.

[0035] In one embodiment, the frame further includes a feeding table 112. The feeding table 112 and the shearing table 111 are fixed to each other. The feeding table 112 and the shearing table 111 are located upstream of the shearing table 111. The feeding mechanism 120 is arranged on the feeding table 112, and the tabletop of the feeding table 112 is flush with or slightly higher than the tabletop of the shearing table 111 to facilitate the feeding mechanism 120 to push the high-purity material on the feeding table 112 into the shearing table 111.

[0036] Further, the frame further includes a material receiving table 113. The feeding table 112 and the material receiving table 113 are respectively located on both sides of the shearing table 111. The feeding structure pushes the high-purity material into the shearing table 111. After the cutting knife 132 cuts the high-purity material, due to the continuous feeding of the feeding mechanism 120, the cut high-purity material is pushed to the material receiving table 113, and the material is discharged through the material receiving table 113.

[0037] In one embodiment, the feeding mechanism 120 further includes a feeding driving member 122. The feeding driving member 122 is disposed on the feeding table 112, and the feeding driving member 122 is connected to the pushing member 121 to drive the pushing member 121 to reciprocate, so that the pushing member 121 approaches and moves away from the shearing table 111. When the pushing member 121 approaches the shearing table 111, the high-purity material on the feeding table 112 can be pushed into the shearing table 111.

[0038] Further, the pushing member 121 includes a connecting portion and a pushing portion 1212 which are connected to each other. The connecting portion is connected to the feeding driving member 122, and the pushing portion 1212 is disposed at an angle with the connecting portion. The pushing portion 1212 is used to push the high-purity material. By providing the connecting portion, the pushing portion 1212 and the feeding driving member 122 can be spaced apart, which is convenient for pushing the material.

[0039] Furthermore, the feeding mechanism 120 includes a lead screw module 123. The feeding driving member 122 is connected to the lead screw module 123, the connecting portion is connected to the lead screw module 123, and the pushing portion 1212 is spaced apart from the lead screw module 123. In Figure 1 the illustrated embodiment, the extending direction of the lead screw is the same as the moving direction of the pushing member 121. Therefore, by providing the connecting portion, the pushing portion 1212 and the lead screw module 123 can be spaced apart, which is convenient for pushing the material.

[0040] Optionally, the feeding driving member 122 is a motor.

[0041] In one embodiment, the pushing member 121 is rotatably connected to the lead screw module 123, and the pushing member 121 can pass through a material placing position and a pushing position during rotation. When the pushing member 121 is located at the material placing position, the pushing portion 1212 of the pushing member 121 is away from the table surface of the feeding table 112 to facilitate placing the high-purity material; when the pushing member 121 is located at the pushing position, the pushing member 121 can act with the lead screw module 123 to push the high-purity material.

[0042] In one embodiment, the shearing device further includes a feeding protective cover 114. The feeding protective cover 114 is disposed on the feeding table 112 and is arranged corresponding to the lead screw module 123.

[0043] In one embodiment, the shearing device further includes a shearing protective cover 115. The shearing protective cover 115 is disposed on the shearing table 111 and forms a shearing space 116 and a material passing channel 117 with the shearing table 111. The cutting knife 132 is located in the shearing space 116. The material passing channel 117 penetrates through the shearing space 116 along the conveying direction of the high-purity material to allow the high-purity material to pass through. The cutting knife 132 is used to shear the high-purity material in the material passing channel 117. The shearing protective cover 115 can provide protection during the shearing process and can also protect the shearing mechanism 130.

[0044] Specifically Figure 1 In the illustrated embodiment, the feeding mechanism 120 and the receiving table 113 are respectively arranged corresponding to the two ends of the material passing channel 117. In this way, the feeding mechanism 120 pushes the high-purity material to enter from one end of the material passing channel 117, the cutting knife 132 shears the high-purity material in the material passing channel 117, and the sheared high-purity material is output from the other end of the material passing channel 117 to the receiving table 113.

[0045] Please refer to Figure 3 and Figure 4 In one embodiment, the shearing mechanism 130 further includes a movable plate 133, a pressing plate 134 and an elastic member 135. The hydraulic driving member 131 is connected to the movable plate 133 to drive the movable plate 133 to move reciprocally. The pressing plate 134 is movably connected to the movable plate 133 in a reciprocating manner. The elastic member 135 is disposed between the pressing plate 134 and the movable plate 133 and is used to provide a force for the pressing plate 134 to move away from the movable plate 133.

[0046] During the process of the movable plate 133 moving towards the high-purity material at the shearing table 111, the pressing plate 134 can move along with the movable plate 133 and press the high-purity material tightly, and the cutting knife 132 can shear the high-purity material pressed by the pressing plate 134. In this way, the stability of shearing can be ensured, the shearing precision can be improved, and the high-purity material can be prevented from shifting during the shearing process.

[0047] Further, the pressing plate 134 is provided with a through hole. During the process of the pressing plate 134 moving relative to the movable plate 133, the cutting knife 132 can pass through the through hole to shear the high-purity material under the pressing plate 134, thereby further improving the stability of shearing.

[0048] Specifically Figure 3 In the illustrated embodiment, the movable plate 133 moves reciprocally in the vertical direction, the pressing plate 134 moves reciprocally in the vertical direction relative to the movable plate 133, and the pressing plate 134 is located below the movable plate 133. The pressing plate 134 is provided with a through hole in the vertical direction. Preferably, before the pressing plate 134 contacts the high-purity material, the cutting knife 132 is located above the pressing plate 134.

[0049] Optionally, the elastic member 135 is a spring.

[0050] In one embodiment, the shearing mechanism 130 further includes a mounting plate, a first guide post 136 and a second guide post 137. The mounting plate is disposed on the shearing table 111. The first guide post 136 is connected to the mounting plate so as to be reciprocally movable in the vertical direction. The movable plate 133 is connected to the first guide post 136. The second guide post 137 is connected to the movable plate 133 so as to be reciprocally movable in the vertical direction. The pressing plate 134 is connected to the second guide post 137.

[0051] Specifically Figure 2 In the illustrated embodiment, the shearing mechanism 130 further includes a connecting plate 138. The hydraulic driving member 131 is connected to the connecting plate 138. The connecting plate 138 and the movable plate 133 are respectively connected to opposite ends of the first guide post 136 to facilitate the installation of the hydraulic driving member 131. For example Figure 2 the hydraulic driving member 131 can be disposed inside the shearing table 111.

[0052] In one embodiment, the shearing device further includes a first grating 141 and a second grating 142. The first grating 141 and the second grating 142 are disposed on the frame at intervals. The cutting knife 132 is located between the first grating 141 and the second grating 142 to stop the shearing mechanism 130 or the shearing device when a finger extends between the first grating 141 and the second grating 142, thereby further improving the safety of use.

[0053] Optionally, both the first grating 141 and the second grating 142 are finger-level to ensure that a finger extending between the first grating 141 and the second grating 142 is detected.

[0054] In one embodiment, the shearing device further includes a controller 143 and two series-connected start buttons. The controller 143 is connected to the hydraulic driving member 131 and the two start buttons. The two start buttons are disposed on the frame at intervals. In this way, the double start button setting is adopted to further prevent a finger from extending to the cutting knife 132, improving safety. In addition, the controller 143 is also connected to the feeding driving member 122 to ensure that the feeding driving member 122 also moves synchronously after the start button is pressed.

[0055] To facilitate understanding of the technical solution of the present application, the working process of the shearing device in the above embodiment is described herein in conjunction with Figure 2 and Figure 3 as follows:

[0056] The operator places the high-purity material to be sheared on the feeding table 112. Next, press two start buttons simultaneously, the feeding driving member 122 operates, and the pusher 121 pushes the high-purity material into the material-passing channel 117. The hydraulic driving member 131 drives the movable plate 133 to descend. The pressing plate 134 first presses the high-purity material in the material-passing channel 117, and then the cutting knife 132 passes through the through-hole and shears the high-purity material. After the shearing is completed, the movable plate 133 ascends, the feeding driving member 122 operates again, pushes the high-purity material to continue to be conveyed, and pushes the sheared high-purity material out of the material-passing channel 117 to the receiving table 113.

[0057] It can be understood that, in order to cooperate with the phased movement of the cutting knife 132, the feeding driving member 122 can adopt a stepping motor. In addition, the descent of the movable plate 133 is achieved by pressing two start buttons simultaneously, and the ascent of the movable plate 133 can be that the movable plate 133 automatically returns to the original position after the start buttons are released.

[0058] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
