DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0031] like Figures 1 to 6 As shown, this embodiment proposes a graphite-doped high-conductivity self-baking electrode paste discharging and dividing device, including a raw material barrel 11, in which a screw feeder is rotatably connected, and the screw feeder can realize the feeding of materials. The raw material barrel 11 includes a discharge port and an inlet. The material falling into the inlet can be transported to the discharge port via the screw feeder, and then the discharge is realized. The setting method of the screw feeder can prevent too much feeding at one time, thereby controlling the feeding amount each time.

[0032] A cutter 14 is slidably arranged at the discharge port, and a collecting box 5 is arranged below the discharge port; the collecting box 5 is divided into a small standard box 51, a qualified box 52 and a large standard box 53, and a load-bearing box 54 for receiving materials is arranged in the small standard box 51 and the large standard box 53, wherein the qualified box 52 is located between the small standard box 51 and the large standard box 53, the load-bearing box 54 of the small standard box 51 is used to receive smaller cut blocks, and the load-bearing box 54 of the large standard box 53 is used to receive larger cut blocks.

[0033] When the load-bearing box 54 in the small standard box 51 descends, it indicates that more small cutting blocks are taken up at this time, which can drive the cutter 14 to move slower, thereby reducing the frequency of cutting. When the load-bearing box 54 in the large standard box 53 descends, it indicates that more large cutting blocks are taken up at this time, which can drive the cutter 14 to move faster, thereby increasing the frequency of cutting.

[0034] The outer wall of the raw material barrel 11 is slidably connected with a slide bar 12, which can only slide in the horizontal direction. The slide bar 12 is fixedly connected to the cutter 14, and the slide bar 12 is fixedly connected to a guide frame 13, and the guide frame 13 and the slide bar 12 are vertically arranged.

[0035] It also includes a frame, which is rotatably connected to a conical wheel 21. The conical wheel 21 can only rotate. The conical wheel 21 is eccentrically connected to a sliding shaft. The guide frame 13 is provided with a sliding groove. The sliding shaft is movably arranged in the sliding groove. When the conical wheel 21 drives the sliding shaft to rotate, the sliding shaft slides in the sliding groove, which can drive the cutter 14 to move back and forth, thereby realizing cutting of the material.

[0036] The first motor 23 also includes a first motor 23, which is connected to a friction wheel 22. The friction wheel 22 and the conical wheel 21 are in contact. The first motor 23 is connected to a controller. The first motor 23 can drive the friction wheel 22 to rotate. The friction wheel 22 can drive the conical wheel 21 to rotate. The friction wheel 22 only needs to rotate in one direction to drive the reciprocating motion of the cutter 14. The friction wheel 22 and the conical wheel 21 are in a contact friction relationship. Under the action of friction, the friction wheel 22 can drive the conical wheel 21 to rotate.

[0037] The frame is fixedly connected with an electric push rod 25 arranged in the vertical direction, and the electric push rod 25 is connected with a lifting seat 26. The lifting seat 26 is slidably connected to the frame, and the lifting seat 26 can only slide in the vertical direction. The lifting seat 26 can drive the first motor 23 to move vertically, and the electric push rod 25 is connected to the controller.

[0038] The lifting seat 26 is slidably connected to a slide 24 that moves horizontally. The slide 24 is fixedly connected to the first motor 23. The slide 24 is connected to the lifting seat 26 through a first spring 27. The first spring 27 is arranged in the horizontal direction. One end of the first spring 27 is connected to the slide 24, and the other end is connected to the lifting seat 26. The slide 24 can only slide in the horizontal direction.

[0039] The first spring 27 is always in a compressed state. When the lifting seat 26 drives the friction wheel 22 to descend, the first spring 27 can drive the friction wheel 22 to move toward the direction close to the conical wheel 21, so that the friction wheel 22 and the conical wheel 21 are always in a contact state, so that when the friction wheel 22 rotates, the conical wheel 21 can be driven to rotate.

[0040] A lifting rod 55 is provided in the small standard box 51 and the large standard box 53 respectively. The lifting rod 55 is slidably connected to the collection box 5 . The lifting rod 55 is connected to the collection box 5 via a second spring 56 .

[0041] The lifting rod 55 is arranged in a vertical direction, and the second spring 56 is sleeved on the lifting rod 55. One end of the second spring 56 is connected to the lifting rod 55, and the other end is connected to the collecting box 5. When the load-bearing box 54 receives materials, the lifting rod 55 can be driven down to deform the second spring 56.

[0042] The frame is connected to a first switch 57 and a second switch 58. The first switch 57 is located below the lifting rod 55 in the small standard box 51, and the second switch 58 is located below the lifting rod 55 in the large standard box 53. In the initial state, under the action of the second spring 56, a suitable gap is left between the lifting rod 55 and the switch.

[0043] The first switch 57 and the second switch 58 are both connected to the controller. The conical wheel 21 is narrow at the bottom and wide at the top. When the lifting rod 55 and the first switch 57 are in contact, the first switch 57 can control the electric push rod 25 to rise, and the movement frequency of the cutter 14 becomes slower. When the lifting rod 55 and the second switch 58 are in contact, the second switch 58 can control the electric push rod 25 to descend, and the movement frequency of the cutter 14 becomes faster.

[0044] The frame is rotatably connected to two sorting rollers 41, which are located below the discharge port. The two sorting rollers 41 are respectively fixedly connected to gears 42, and the two gears 42 are meshed. One of the sorting rollers 41 is connected to a second motor 43, and the second motor 43 can drive the two sorting rollers 41 to rotate in opposite directions.

[0045] The distance between the two sorting rollers 41 is variable, wherein the smaller end is located above the small standard box 51, the larger end is located above the large standard box 53, and the middle part is located above the qualified box 52. By setting the relatively rotatable sorting rollers 41, the sorting work of cut blocks of different sizes can be realized. Example

[0046] Reference Figures 1 to 6 The other structures are the same as those in the first embodiment, except that the dumping problem of the materials in the load-bearing box is taken into consideration in this embodiment.

[0047] The lifting rod 55 is hinged to the load-bearing box 54, and the load-bearing box 54 is connected to the lifting rod 55 through a first torsion spring. The setting of the first torsion spring can make the load-bearing box 54 in a vertical state in the initial state. The load-bearing box 54 is hinged with a baffle 32, and the upper end of the baffle 32 is hinged to the load-bearing box 54, and the baffle 32 is connected to the load-bearing box 54 through a second torsion spring. The setting of the second torsion spring can make the baffle 32 keep the load-bearing box 54 in a closed state.

[0048] A push rod 31 is fixedly connected to one side of the load-bearing box 54. When the push rod 31 contacts the collecting box 5 and the weight of the collecting box 5 continues to increase, the load-bearing box 54 can rotate around the lifting rod 55. At this time, the material drives the baffle 32 to open, and the material in the load-bearing box 54 can be automatically dumped, so that a new round of cutting block collection can be carried out. The material in the load-bearing box 54 can be automatically discharged without stopping the machine, which effectively improves the processing efficiency.

[0049] The specific working process is as follows: the material falls through the discharge port of the raw material barrel 11, the first motor 23 drives the friction wheel 22 to rotate, the friction wheel 22 drives the conical wheel 21 to rotate, the conical wheel 21 drives the cutter 14 to reciprocate horizontally to achieve cutting of the material, the second motor 43 drives the two sorting rollers 41 to rotate towards each other, and the cut blocks of different sizes fall into the small standard box 51, the qualified box 52 and the large standard box 53 respectively, to achieve the sorting of the cut blocks.

[0050] Taking the small standard box 51 as an example, when the number of cutting blocks in the small standard box 51 is large, the cutting blocks drive the load-bearing box 54 in the small standard box 51 to descend, and the load-bearing box 54 drives the lifting rod 55 to descend, and the lifting rod 55 contacts the first switch 57. The first switch 57 transmits a corresponding signal to the controller, and the controller controls the electric push rod 25 to rise, so that the friction wheel 22 and the wider end of the conical wheel 21 contact each other. When the rotation speed of the friction wheel 22 is constant, the rotation speed of the conical wheel 21 slows down, so that the reciprocating speed of the cutter 14 slows down, thereby reducing the frequency of cutting.

[0051] As the load-bearing box 54 descends, when the top rod 31 contacts the collecting box 5, and the weight of the collecting box 5 continues to increase, the load-bearing box 54 can rotate around the lifting rod 55. At this time, the material drives the baffle 32 to open, and the material in the load-bearing box 54 can be automatically dumped. After that, the second spring 56 drives the load-bearing box 54 to reset, realizing a new round of material reception.

[0052] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
