[0029] In order to better understand the technical scheme of the utility model, the utility model will be described in detail below in conjunction with the drawings.
[0030] In the embodiment 1 of the cutting equipment (hereinafter referred to as cutting equipment) for producing recycled stone in the utility model, the cutting equipment comprises an operation table 1 and a cutting knife 6 rotatably arranged on the operation table 1.
[0031] The cutting knife 6 can conveniently cut the raw materials during rotation. The operation table 1 comprises a supporting leg and an operation table 1 surface located on the supporting leg. In order to conveniently cut the raw materials, part of the cutting edges of the cutting knife 6 protrude from the operation table 1 surface of the operation table 1. During the rotation of the cutting knife 6, the objects on the operation table 1 surface can be cut. In order to avoid hurting the workers during cutting, a clamping seat for clamping the raw materials is further arranged on the operation table 1. The clamping seat is guidingly arranged on the operation table 1, so that the clamping seat can move relative to the operation table 1, thereby avoiding the danger of manually taking the raw materials. The cutting knife 6 is arranged on one end of the operation table 1, and the initial position of the clamping seat is arranged on the other end of the operation table 1. The movement direction of the clamping seat is consistent with the edge extension direction of the cutting knife 6.
[0032] Specifically, the clamping seat comprises a bottom plate 2 abutting against the operation table 1 surface and clamping plates 5 located on both sides and perpendicular to the bottom plate 2. The clamping plates 5 on both sides are guidingly arranged on the bottom plate 2. The bottom plate 2 is provided with an avoiding groove for avoiding the cutting knife 6 during guiding movement. The avoiding groove is a long and narrow straight through groove. The bottom of the clamping plate 5 is provided with a sliding block 51, and the bottom plate 2 is provided with a sliding groove 21 accommodating the sliding block 51. The sliding groove 21 and the sliding block 51 are correspondingly arranged. Two sliding grooves 21 are arranged on both sides of the bottom plate 2, and two sliding blocks 51 are arranged on the bottom of each clamping plate 5. The extension direction of the sliding groove 21 is perpendicular to the edge extension direction of the cutting knife 6, so as to limit the movement direction of the clamping plate 5, so that the clamping plate 5 can only move along the predetermined direction, that is, relatively close to complete clamping of the raw materials or relatively far away to complete release of the raw materials.
[0033] In order to facilitate automatic clamping, the cutting device is further provided with a driving assembly 4 for driving the two clamping plates 5 to relatively approach or relatively move away from each other. The driving assembly 4 comprises a driving motor 41 for generating driving force, which constitutes a first rotary power source. A bidirectional threaded rod 45 is drivingly connected to the driving motor 41, and the bidirectional threaded rod 45 is provided in sections. Two sections at both ends are threaded sections with opposite screw directions. The two clamping plates 5 on the clamping seat are respectively provided with threaded holes matched with one end of the bidirectional threaded rod 45. When the bidirectional threaded rod 45 rotates, the two clamping plates 5 on both sides will relatively approach or relatively move away from each other, thereby facilitating clamping and releasing of the clamping plates 5. In order to facilitate driving of the bidirectional threaded rod 45, a transmission section for driving connection with the driving motor 41 is further arranged at the middle section of the bidirectional threaded rod 45. The transmission section and the driving motor 41 are drivingly connected through a belt. In order to prevent the belt from sliding on the bidirectional threaded rod 45 and thereby affecting the normal work of the threaded section, a disc-shaped limiting disc 44 for limiting the transmission belt 43 on the transmission section is arranged between the transmission section and the threaded sections at both ends. In order to reduce the shaking of the bidirectional threaded rod 45, support columns for supporting the bidirectional threaded rod 45 are further arranged at both ends of the bidirectional threaded rod 45 on the bottom plate 2. The support columns have accommodating holes for accommodating the end portions of the bidirectional threaded rod 45.
[0034] Of course, in other embodiments, the driving motor 41 and the bidirectional threaded rod 45 can be drivingly connected by a chain or by a gear. Alternatively, in other embodiments, a cylinder can be arranged on the outer side of each clamping plate 5, and the output end of the cylinder is connected to the outer side of the clamping plate 5, thereby facilitating pushing of the clamping plate 5 to relatively approach the two clamping plates 5. Alternatively, in other embodiments, the first rotary power source can be a rotary cylinder. Of course, in other embodiments, the support columns can not be arranged, and the bidirectional threaded rod can be maintained at a certain height by the clamping plates 5.
[0035] In order to facilitate the relative movement of the clamping seat on the operation table 1, a pushing assembly 3 is further arranged on the operation table 1, the pushing assembly 3 comprises a second rotating power source, specifically a pushing motor 31, a guide groove 11 is arranged on the operation table 1, and a guide block 22 is arranged below the bottom plate 2 of the clamping seat and cooperates with the guide groove 11. The guide block 22 and the guide groove 11 are arranged to enable the operation table 1 to move in a predetermined direction, so as to avoid the movement direction of the operation table 1 to form an angle with the cutting direction of the blade and cause the blade to break. A lead screw 32 is arranged on the output end of the pushing motor 31, the axis of the lead screw 32 is collinear with the axis of the output shaft of the pushing motor 31, and the extension direction of the axis of the lead screw 32 is consistent with the extension direction of the cutting blade 6. A threaded hole is further arranged on the guide block 22 and cooperates with the lead screw 32, and the guide block 22 also functions as a nut block that cooperates with the lead screw 32, so that the structure is simplified.
[0036] A door type frame 7 is further arranged on the operation table 1 at the position of the cutting blade 6, the door type frame 7 comprises two side columns and a top beam arranged on the top of the side columns, and the door type frame 7 surrounds the part of the cutting blade 6 that is exposed on the operation table 1. Generally, a large amount of dust is generated during the cutting of raw materials, and the dust diffused into the air will cause pollution, so a dust extraction assembly 9 for collecting dust during the cutting process is further arranged on the door type frame 7. Specifically, the dust extraction assembly 9 comprises a dust extraction cover 94 arranged on the column and a dust collection box 8 arranged on the top beam of the door type frame. The dust extraction cover 94 is a block type structure with an opening, and a dust collection pipe is further arranged at the opening of the dust extraction cover 94, the dust collection pipe is connected to the dust collection box 8, and the dust collection pipe comprises a first dust collection pipe 92 extending horizontally and a second dust collection pipe 93 extending vertically, the first dust collection pipe 92 and the second dust collection pipe 93 are connected to each other, and a dust extraction pump 91 is arranged on the dust collection box 8, which can generate suction force. A filter screen 81 is arranged on one side of the dust collection box 8, air can pass through the filter screen 81 normally, and dust will be collected on the filter screen 81. In order to facilitate recycling, an openable sealing plate 82 is further arranged on the side of the dust collection box 8 away from the filter screen 81, so as to facilitate cleaning or replacement of the filter screen 81. That is, under the working state of the dust collection box 8 and the dust extraction pump 91, negative pressure can be generated, so that the gas around the dust extraction member continuously flows to the dust extraction member, and then enters the dust collection box 8 through the dust collection pipe. After the dust is collected in the dust collection box 8, clean air is released into the atmosphere, and the cycle is repeated, so that the dust is collected in the dust collection box 8.
[0037] When work is needed, first, the raw material is placed on the clamping seat, the driving motor 41 is started, the clamping plates 5 on both sides are relatively close, the raw material to be processed is clamped, then the pushing motor 31 is started, the pushing motor 31 drives the clamping seat to move towards the cutting knife, and then the cutting knife is cut into smaller stone blocks. The dust generated in the cutting process will be sequentially introduced into the dust collecting box 8 through the dust collecting cover 95, the second communication pipe 93 and the first communication pipe 92 under the action of the dust extraction pump 91, and then concentrated on the filter screen 81 of the dust collecting box 8.
[0038] It should be clear that the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
