Description

Technical Field

[0001] The present invention relates to the technical field of slitting equipment, and particularly relates to a dust-free carbon rod slitter. Background Art

[0002] According to different market demands, it is sometimes necessary to perform standardized slitting on the length of carbon rods before they leave the factory. As Figure 1 shown, the body of the existing carbon rod slitter adopts a chain conveyor 1. The carbon rod 2 is conveyed on the chain 3, and the carbon rod 2 on the chain is slit by a horizontal slitting knife group 4 above the body. During the use of this equipment, a large amount of dust 5 from the slit carbon rods escapes, causing serious pollution to the production workshop environment by the carbon rod dust 5. To solve this problem, we need to redesign a slitter that can better solve the problem of dust escape during carbon rod slitting. Summary of the Invention

[0003] Based on the above problems, the purpose of the present invention is to provide a dust-free carbon rod slitter, which solves the problem of a large amount of dust escaping during the slitting process of existing slitting equipment by redesigning the main mechanism of carbon rod slitting.

[0004] The technical solution of the present invention is as follows: A dust-free carbon rod slitter includes a main shaft, a runner, a cutter shaft, a slitting knife, and a dust-proof cover body. The runners are arranged at intervals on the main shaft. A carbon rod receiving groove is provided on the outer periphery of the runner. The cutter shaft is located obliquely above the main shaft. Slitting knives are arranged at intervals on the cutter shaft. The slitting knives are located between two adjacent carbon rod receiving grooves on the left and right. The upper part of the dust-proof cover body covers the cutter shaft and the slitting knives, and the front edge of its upper part is close to the carbon rod receiving groove. A dust suction pipe joint is provided at the rear end of the middle part of the dust-proof cover body. The dust suction pipe joint is connected to a dust suction mechanism. The lower part of the dust-proof cover body is a hopper structure, and the front upper edge of the hopper structure is close to the carbon rod receiving groove.

[0005] During operation, the rotation of the main shaft drives the synchronous rotation of several runners on the main shaft, and the rapid rotation of the cutter shaft drives the rapid rotation of the slitting knives on the cutter shaft. The carbon rods are placed in the carbon rod receiving grooves and are sent to the slitting knives one by one as the main shaft rotates, realizing the slitting process. The dust-proof cover body has a unique design. It not only fully encloses the cutter shaft and the slitting knives thereon, but also semi-encloses the runners, including the lower area of the runners, thereby comprehensively containing the dust generated during the slitting process and timely evacuating it through the dust suction mechanism, thus solving the problem of dust escape during slitting.

[0006] For the positioning and fixing of the runner on the main shaft, it can be handled according to the positioning and fixing principles of the existing shafting structure. Similarly, for the positioning and fixing of the slitting knife on the knife shaft, it can be handled according to the positioning and fixing principles of the existing shafting structure. For example: A runner shaft sleeve is arranged between two adjacent runners on the main shaft. The distance between two adjacent runners is controlled by the runner shaft sleeve, so that the distance between two corresponding carbon rod accommodation grooves on two adjacent runners exactly meets the minimum requirements for the operation of the slitting knife. Similarly, a tool shaft sleeve is arranged between two adjacent slitting knives on the knife shaft. The distance between two adjacent slitting knives is controlled by the tool shaft sleeve, so that the slitting knife can be located between two corresponding carbon rod accommodation grooves.

[0007] The function of the dust suction mechanism is to timely suck away the dust in the dust-proof cover body, and usually a fan is used for suction. In order to realize the collection of dust and the purification of tail gas, a cyclone dust collector and / or a bag dust collector are also configured on the suction pipeline. For example: Connect the inlet of the cyclone dust collector to the dust suction pipe joint, connect the outlet of the cyclone dust collector to the bag dust collector, and connect the outlet of the bag dust collector to the fan.

[0008] In order to enable the carbon rod dust-free slitting machine of the present invention to better adapt to the slitting requirements of carbon rods with different thicknesses and sizes, the present invention further gives the following optimization scheme: The two side walls of the carbon rod accommodation groove are detachable side walls, so that the distance between the two side walls is adjustable to adapt to the accommodation requirements of carbon rods with different thicknesses.

[0009] The upper cover body of the dust-proof cover body is hinged to its middle cover body, so that the upper cover body can be flipped along its hinge axis, and a flip angle positioning and fixing structure is also arranged between the upper cover body and the middle cover body.

[0010] The flip angle positioning and fixing structure includes a hook. The upper end of the hook is hinged on the upper cover body. The hook straddles the hinge axis, and the lower end of the hook is detachably fixed on the middle cover body, and the fixing position of the lower end of the hook on the middle cover body is adjustable.

[0011] An arc-shaped pressing plate is arranged at the front edge of the upper cover body of the dust-proof cover body to press the carbon rod to be slit in the carbon rod accommodation groove.

[0012] The beneficial effects of the present invention are as follows: The main structure of the slitting machine of the present invention adopts a design in which the runner and the slitting knife are tangent to each other, and the two are obliquely arranged, which is convenient for the collection and control of dust during slitting. In addition, the dust-proof cover body has a unique design. It not only fully surrounds the knife shaft and the slitting knife thereon, but also semi-surrounds the runner, including the lower area of the runner, so as to comprehensively contain the dust generated during the slitting process and timely extract it through the dust suction mechanism, thereby solving the problem of dust leakage during slitting.

Detailed implementation manners

[0019] To describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the implementation manners and with reference to the accompanying drawings.

[0020] As Figure 2 shown, the carbon rod dust-free slitter of the present invention includes a main shaft 6, a plurality of runners 7, a cutter shaft 8, a plurality of cutting knives 9 and a dust-proof cover body 10. The main shaft 6 and the cutter shaft 8 are parallel to each other, and the cutter shaft 8 is located obliquely above the right of the main shaft 6.

[0021] As Figure 3 shown, a plurality of runners 7 are arranged at intervals on the main shaft 6, and a carbon rod accommodation groove 11 is uniformly arranged on the outer peripheral surface of each runner 7. A plurality of cutting knives 9 are arranged at intervals on the cutter shaft 8 to form a cutting knife group, and each cutting knife is correspondingly distributed between two adjacent left and right carbon rod accommodation grooves 11.

[0022] As Figure 2 and 3 shown, the upper part of the dust-proof cover body 10 covers the cutting knife group, that is, the cutter shaft 8 and a plurality of cutting knives 9, and the front edge of the upper part of the dust-proof cover body 10 (that is, Figure 2At point B in the figure), it is close to the carbon rod accommodation groove 11, reducing the space for dust to escape upwards and towards the front side; at the rear end of the middle part of the dust-proof cover body 10, there is a dust suction pipe joint 12, and the dust suction pipe joint 12 is connected to the dust suction mechanism. The lower part of the dust-proof cover body 10 is a hopper structure, and the cut carbon rods will be discharged from the lower discharge port of the hopper structure. The upper front edge of the hopper structure (i.e., Figure 2 At point C in the figure), it is close to the carbon rod accommodation groove 11, reducing the space for dust to escape downwards and towards the front side.

[0023] In order to enable the carbon rod dust-free cutting machine of the present invention to better adapt to the cutting requirements of carbon rods of different thicknesses and sizes, the present invention further provides the following optimization solutions: The front and rear side walls of the carbon rod accommodation groove 11 are detachable side walls, so that the distance between the front and rear side walls is adjustable to adapt to the accommodation requirements of carbon rods of different thicknesses.

[0024] The upper cover body 10.1 of the dust-proof cover body 10 ( Figure 2 The upper arc part of the dust-proof cover body 10 in the figure) is hinged to the middle cover body 10.2 of it ( Figure 2 The middle vertical part of the dust-proof cover body 10 in the figure), so that the upper cover body of the dust-proof cover body 10 can be flipped along its hinge axis 19, and a flip angle positioning and fixing structure 20 is also provided between the upper cover body 10.1 and the middle cover body 10.2.

[0025] The flip angle positioning and fixing structure 20 includes a hook. The upper end of the hook is hinged to the upper cover body 10.1. The hook straddles the hinge axis 19, and the lower end of the hook is detachably fixed to the middle cover body 10.2. The fixing position of the lower end of the hook on the middle cover body 10.2 is adjustable.

[0026] At the front edge of the upper cover body 10.1 of the dust-proof cover body 10, a plurality of arc-shaped pressing plates 21 are arranged at intervals along the axial direction to press the carbon rods to be cut in the carbon rod accommodation groove.

[0027] As Figure 3 shown, between two adjacent runners 7 on the main shaft 6, there is a runner shaft sleeve 14. By controlling the distance between two adjacent runners through the runner shaft sleeve 14, the distance between two corresponding carbon rod accommodation grooves on two adjacent runners exactly meets the minimum requirements for the working of the cutting knife. Similarly, between two adjacent cutting knives 9 on the knife shaft 8, there is a tool shaft sleeve 15. By controlling the distance between two adjacent cutting knives 9 through the tool shaft sleeve 15, the cutting knife 9 can be located between two corresponding carbon rod accommodation grooves 11.

[0028] During operation, the main shaft 6 rotates to drive a number of runners 7 on the main shaft to rotate synchronously, and the cutter shaft 8 rotates rapidly to drive the slitting knives 9 on the cutter shaft to rotate rapidly. The carbon rod 2 is placed in the carbon rod accommodation groove 11 and is sent to the slitting knives 9 one by one as the main shaft 6 rotates, realizing the slitting process. The dust-proof cover body 10 is uniquely designed. It not only fully encloses the cutter shaft 8 and the slitting knives 9 thereon, but also semi-encloses the runners 7, including the lower region of the runners 7, thereby comprehensively containing the dust 2 generated during the slitting process and timely evacuating it through the dust suction mechanism, thus solving the problem of dust leakage during slitting.

[0029] The function of the dust suction mechanism is to timely suck away the dust in the dust-proof cover body, and usually a blower 16 is used for suction. In order to realize the collection of dust and the purification of tail gas, a cyclone dust collector 17 and / or a bag filter 18 are also arranged on the suction pipeline. As Figure 4 shown, the inlet of the cyclone dust collector 17 is connected to the dust suction pipe joint, the outlet of the cyclone dust collector 17 is connected to the bag filter 18, and the outlet of the bag filter 18 is connected to the blower 16.

[0030] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, are all included in the patent protection scope of the present invention.
