Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and particularly relates to a cutting device for concrete products. Background Art

[0002] Traditional cutting devices for concrete products expose many limitations when facing complex cutting requirements. Currently, most common cutting devices on the market only have a single cutting function and cannot simultaneously meet the flexible adjustment of cutting angle and depth. For example, when making concrete products with specific inclined angles, existing cutting equipment often fails to achieve precise angle cutting, resulting in insufficient product precision and inability to meet the requirements of architectural design. This not only increases the waste rate but also causes waste of raw materials.

[0003] On the other hand, for situations where precise control of cutting depth is required, existing cutting devices are equally incompetent. When cutting concrete products of different thicknesses, problems such as too deep or too shallow cutting depth often occur. Too deep cutting depth will damage the structure of the concrete product, affecting its strength and stability; too shallow cutting depth cannot meet the requirements of subsequent processing or use, requiring secondary cutting, reducing production efficiency and increasing production costs.

[0004] In addition, existing cutting devices for concrete products also have defects in the feeding mechanism. The feeding process is not smooth and precise enough, easily causing displacement of the concrete product during cutting, affecting cutting accuracy. Moreover, the feeding speed often cannot be flexibly adjusted according to the requirements of the cutting process, further restricting the improvement of cutting efficiency and quality. In view of the above problems, the present invention provides a cutting device for concrete products. Summary of the Invention

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment: As Figure 1 — Figure 12 shown, a concrete product cutting device includes: A workbench 1, the workbench 1 includes an operation table 101, which plays a supporting role when cutting concrete products; four support arms 102 are fixedly installed on the operation table 101, and support rods 103 are rotatably installed on the support arms 102.

[0030] As Figure 1 、 Figure 2 and Figure 4As shown, during the cutting process, the threaded rod 403 serves to support the conveying table 401. After the cutting is completed, the support rod 103 is rotated relative to the support arm 102, thereby retracting the support rod 103.

[0031] The first cutting mechanism 2 is installed on the operation table 101. The first cutting mechanism 2 includes a cutting tooth disc 210, and the cutting tooth disc 210 is fixedly connected to the output shaft of the second motor 209. As Figure 1 , Figure 2 , Figure 4 shown, a first cutting mechanism 2, a second cutting mechanism 3, and a feeding mechanism 4 are provided on the operation table 101. Different requirements of concrete products can be cut by the first cutting mechanism 2 and the second cutting mechanism 3 to meet the needs of actual projects, and Figure 1 and Figure 2 are schematic diagrams of the state of the present invention during use. When not cutting or during transportation, the first cutting mechanism 2, the second cutting mechanism 3, and the feeding mechanism 4 can be retracted (as Figure 4 shown). On the one hand, the transportation difficulty can be reduced. On the other hand, it can prevent personnel from being injured by touching the cutting tooth disc 210, etc.

[0032] The first cutting mechanism 2 further includes a motor base 207. A second motor 209 and a protective cover 211 are fixedly installed on the motor base 207. The motor base 207 is connected to the flipping assembly through a first rotating shaft 208. When not cutting and when adjusting the cutting angle, the angle of the cutting tooth disc 210 relative to the operation table 101 is adjusted through the flipping assembly.

[0033] As Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, when cutting, the second motor 209 fixedly installed on the motor base 207 is started, and the cutting tooth disc 210 is driven to rotate by the second motor 209, thereby cutting the concrete through the cutting tooth disc 210. The function of the protective cover 211 is to provide protection, prevent people from touching the cutting tooth disc 210, and prevent flying waste chips from causing harm to personnel. When cutting is not required, the cutting tooth disc 210, etc. are retracted through the flipping assembly (as Figure 4 shown). In addition, when the cutting angle needs to be adjusted, the flipping assembly can also adjust the angle of the cutting tooth disc 210 relative to the operation table 101 ( Figure 1 and Figure 2 are both schematic diagrams of vertical cutting).

[0034] The flip assembly includes an L-shaped frame 201, on which a guide block 202 is provided. The L-shaped frame 201 and the guide block 202 are both slidably matched with the operating table 101. A motor 203 is fixedly installed on the L-shaped frame 201. A worm 204 is transmission-connected to the output shaft of the motor 203. The worm 204 is meshed with a worm wheel 205. The worm wheel 205 is connected to a flip frame 206 through a rotating shaft. The flip frame 206 is rotationally matched with a rotating shaft 208, and the rotating shaft is rotationally installed on the L-shaped frame 201.

[0035] like Figure 1 , Figure 5 , Figure 6 As shown, when it is necessary to adjust the cutting angle of the cutting toothed disc 210 or to retract the cutting toothed disc 210 and the motor 209 to Figure 4 When the motor 1 203 fixedly mounted on the L-shaped frame 201 is in the state, the motor 1 203 fixedly mounted on the output shaft of the motor 1 203 is started, so that the worm 1 204 fixedly mounted on the output shaft of the motor 1 203 rotates, and the worm wheel 1 205 meshing with the worm 1 204 rotates on the L-shaped frame 201 through the rotating shaft, so that the rotating shaft drives the turning frame 206 to rotate, and the motor seat 207 connected to the turning frame 206 drives the cutting toothed disc 210 to rotate a certain angle according to actual needs (the turning frame 206, the motor seat 207 and the rotating shaft 1 208 rotate together at this time), and in addition, by applying force to the motor seat 207, the motor seat 207 can be rotated relative to the turning frame 206 through the rotating shaft 1 208 to adjust the angle of the cutting toothed disc 210. In addition, the L-shaped frame 201 and the guide block 202 can also slide on the operating table 101, and of course, the L-shaped frame 201 and the guide block 202 can also be positioned by limiting the movement of the guide block 202.

[0036] The second cutting mechanism 3 is installed on the operating table 101. The second cutting mechanism 3 includes a cutting rope 303. The cutting rope 303 is connected to three pulleys 302. The cutting rope 303 is driven by the pulleys 302 to rotate to cut the concrete product.

[0037] The second cutting mechanism 3 also includes a moving plate 301, which is movably mounted on the supporting assembly through a moving module 308, and a motor four is fixedly mounted on the moving plate 301, the output shaft of the motor four is connected to a pulley one 302, and the other two pulleys one 302 are symmetrically arranged at one end of two rotating arms 307, and the other end of the rotating arm 307 is connected to a worm gear two 306, and the two worm gears two 306 are distributed on both sides of the worm gear two 305, and the worm gear two 306 is meshed with the worm gear two 305, and the worm gear two 305 is fixedly mounted on the output shaft of the motor three 304, and the motor three 304 is fixedly mounted on the moving plate 301.

[0038] Specifically, the moving module 308 includes a guide rail and an electromagnetic slider. When the electromagnetic slider is energized, it can slide on the guide rail. As a prior art, those skilled in the art can implement it. The guide rail is installed on the third support rod 316, and the electromagnetic slider is installed on the moving plate 301.

[0039] As Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 As shown, when cutting is required through the cutting rope 303, the cutting rope 303 needs to be driven to rotate by the first pulley 302, so as to cut the concrete through the cutting rope 303. Specifically, the fourth motor fixedly installed on the moving plate 301 is started to make the first pulley 302 fixed on the output shaft of the fourth motor rotate, so that the other two first pulleys 302 rotate on the rotating arm 307, and at the same time the cutting rope 303 rotates to cut the concrete placed on the conveying table 401. According to different requirements, the cutting speed needs to be adjusted. When adjusting, the third motor 304 is started to make the output shaft of the third motor 304 drive the second worm 305 to rotate. The second worm gear 306 engaged with the second worm 305 rotates on the moving plate 301, so that the second worm gear 306 drives the rotating arm 307 to rotate. In this way, the distance between the first pulley 302 installed on the rotating arm 307 and the conveying table 401 can be adjusted, that is, the cutting depth is adjusted. At the same time, the cutting rope 303 installed on the first pulley 302 can also be replaced according to the cutting depth.

[0040] The support assembly includes the third support rod 316. The third support rod 316 is connected to the moving module 308. One end of the third support rod 316 is rotatably installed on the second support rod 310. The second support rod 310 is rotatably connected to the first support rod 309. The first support rod 309 is slidably engaged with the arc-shaped groove 314 and the straight groove 315 provided on the operating table 101 through the second rotating shaft 313. The arc-shaped groove 314 and the straight groove 315 are smoothly connected. One end of the second positioning rod 312 is rotatably installed on the second support rod 310. The other end of the second positioning rod 312 is connected to one end of the first positioning rod 311. The other end of the first positioning rod 311 is slidably engaged with the side of the third support rod 316 away from the moving plate 301.

[0041] As Figure 1 — Figure 4 , Figure 7 — Figure 9 As shown, when the first support rod 309, the second support rod 310 and the third support rod 316 are in an open state (as shown in Figure 1 , Figure 2 ), it is in the cutting state. At this time, the first support rod 309, the second support rod 310 and the third support rod 316 play a supporting role for the moving plate 301. When it is necessary to receive Figure 4When in the state of [description], first retract the positioning rod one 311 and the positioning rod two 312 (when the positioning rod two 312 and the positioning rod one 311 are in the straight state, the positioning rod one 311 and the positioning rod two 312 support and position the support rod three 316, so that the support rod three 316 is in the vertical state). Specifically, hold the positioning rod two 312, and then forcefully rotate the positioning rod one 311, so that the end of the positioning rod one 311 that contacts the support rod three 316 clockwise flips to the right side of the contact positioning rod two 312 (taking Figure 9 the perspective as the standard), and then rotate the positioning rod two 312, and retract the positioning rod two 312 into the groove provided in the inner wall of the support rod one 309. Then rotate the support rod three 316 counterclockwise (taking Figure 9 the perspective as the standard), so that the support rod three 316 is retracted into the groove inside the support rod two 310. Similarly, rotate the support rod two 310, and retract the support rod two 310 into the groove inside the support rod one 309. When the storage of the support rod two 310 and the support rod three 316 is completed, push the rotating shaft two 313 upward along the straight groove 315, and then make the rotating shaft two 313 slide into the arc groove 314, so that the support rod one 309 rotates. The support rod one 309 rotates 90 degrees from the vertical state to the horizontal state. It should be noted that dampers are provided at the connection between the support rod one 309 and the support rod two 310, and at the connection between the support rod two 310 and the support rod three 316, that is, the state will not change due to its own gravity, and external force needs to be applied manually to overcome the damper and change the state.

[0042] The feeding mechanism 4, the feeding mechanism 4 is installed on the operating table 101. The feeding mechanism 4 includes a conveying table 401 that is movably installed on the operating table 101. The feeding mechanism 4 further includes two symmetrically arranged threaded rods 403. The threaded rods 403 are rotatably installed on the operating table 101. The conveying table 401 is in threaded cooperation with the threaded rods 403, and the conveying table 401 is in sliding cooperation with the operating table 101. A plurality of positioning grooves 402 are provided on the conveying table 401, and a plurality of clamping components are detachably installed on the positioning grooves 402. The feeding mechanism 4 further includes a motor four 410 fixedly installed on the operating table 101. The output shaft of the motor four 410 is connected to a pulley two 411. The pulley two 411 is connected to a belt 412. Two symmetrically arranged pulley two 411 are also connected to the belt 412. The two pulley two 411 located on both sides of the motor four 410 are respectively installed on the two threaded rods 403.

[0043] As Figure 1 — Figure 2 、 Figure 10 、 Figure 11As shown in the figure, when cutting concrete products, the concrete products are placed on the conveying table 401, and then clamped to the conveying table 401 by the clamping assembly. The conveying table 401 drives the concrete products to move to the cutting position. Specifically, the fourth motor 410 fixedly installed on the operating table 101 is started, and a second pulley 411 fixed on the output shaft of the fourth motor 410 drives the belt 412 to rotate, so that the other two second pulleys 411 connected to the belt 412 rotate. At this time, the threaded rod 403 connected to the second pulley 411 will rotate. The conveying table 401 is in threaded cooperation with the threaded rod 403, so the conveying table 401 slides along the operating table 101 to the target position.

[0044] The clamping assembly includes a lower plate 407. The width of the lower plate 407 is not greater than the width of the positioning groove 402.

A plurality of friction grooves 405 are provided on the side of the pressing plate 404 facing the lower plate 407. An intermediate plate 408 is provided between the pressing plate 404 and the lower plate 407. Bolts 409 are threadedly connected to both sides of the intermediate plate 408.

[0045] As Figure 10 — Figure 12 As shown in the figure, when clamping the concrete products, the cylinder 406 is started, and the extending end of the cylinder 406 drives the pressing plate 404 to move upward, adjusts the height of the pressing plate 404 relative to the concrete products, and finally makes the lower surface of the pressing plate 404 contact the upper surface of the concrete products. The pressing plates 404 in a plurality of clamping assemblies complete the clamping of the concrete products. The friction grooves 405 provided on the pressing plate 404 are to increase the friction force and improve the clamping stability.

[0046] A plurality of positioning grooves 402 are provided on the conveying table 401 to be able to adjust the positions of a plurality of clamping assemblies according to the size of the concrete products. Specifically, when the position of the clamping assembly needs to be adjusted, first rotate the bolt 409 to increase the position of the bolt 409 relative to the lower plate 407, that is, the bolt 409 no longer contacts the conveying table 401, so that the lower plate 407 can be easily rotated relative to the conveying table 401. When the long side direction of the lower plate 407 rotates to coincide with the long side direction of the positioning groove 402, the lower plate 407 and the pressing plate 404 can be taken out from the positioning groove 402, and then the lower plate 407 is placed in another target positioning groove 402, and the bolt 409 is screwed downward again so that the end of the bolt 409 away from the pressing plate 404 can closely adhere to the upper surface of the conveying table 401, thus completing the installation. The width of the lower plate 407 not being greater than the width of the positioning groove 402 is to ensure that the lower plate 407 can be taken out from below the conveying table 401. The length of the lower plate 407 not being greater than the length of the positioning groove 402 is also to facilitate taking out or installing the lower plate 407.
