Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and in particular relates to a concrete product cutting device. Background Art

[0002] Traditional concrete cutting equipment has numerous limitations when faced with complex cutting requirements. Currently, most common cutting devices on the market offer only a single cutting function, unable to flexibly adjust both the cutting angle and cutting depth. For example, when creating concrete products with specific angles, existing cutting equipment often struggles to achieve precise cuts, resulting in products with insufficient precision that fail to meet architectural design requirements. This not only increases scrap rates but also wastes raw materials.

[0003] On the other hand, existing cutting devices struggle when precise control of cutting depth is required. When cutting concrete products of varying thicknesses, the cutting depth often becomes too deep or too shallow. Excessive cutting depth can damage the concrete product's structure, affecting its strength and stability. Too shallow a cutting depth can make it unsuitable for subsequent processing or use, requiring a second cut, reducing production efficiency and increasing costs.

[0004] Furthermore, existing concrete product cutting devices also have drawbacks in their feeding mechanisms. The feeding process is not smooth and precise, which can easily cause the concrete product to shift during cutting, affecting cutting accuracy. Furthermore, the feeding speed often cannot be flexibly adjusted to meet the requirements of the cutting process, further limiting improvements in cutting efficiency and quality. To address these issues, the present invention provides a concrete product cutting device. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example: Figure 1 — Figure 12 A concrete product cutting device is shown, comprising:

[0034] The workbench 1 includes an operating table 101 , which plays a supporting role when cutting concrete products; four support arms 102 are fixedly mounted on the operating table 101 , and support rods 103 are rotatably mounted on the support arms 102 .

[0035] like Figure 1 、 Figure 2 and Figure 4As shown, during the cutting process, the threaded rod 403 plays a role in supporting the conveying platform 401. When the cutting is completed, the support rod 103 is rotated relative to the support arm 102, so that the support rod 103 is retracted.

[0036] The first cutting mechanism 2 is mounted on the operating table 101 and includes a cutting toothed disc 210 fixedly connected to the output shaft of the second motor 209;

[0037] like Figure 1 、 Figure 2 、 Figure 4 As shown, a first cutting mechanism 2, a second cutting mechanism 3 and a feeding mechanism 4 are provided on the operating table 101. The first cutting mechanism 2 and the second cutting mechanism 3 can be used to cut concrete products with different requirements to meet the needs of actual projects, and Figure 1 and Figure 2 This is a schematic diagram of the state of the present invention when in use. When not cutting or in the process of transportation, the first cutting mechanism 2, the second cutting mechanism 3 and the feeding mechanism 4 can be retracted (as shown in FIG. Figure 4 Schematic state), on the one hand, it can reduce the difficulty of transportation, and on the other hand, it can prevent people from being injured by touching the cutting tooth disk 210.

[0038] The first cutting mechanism 2 also includes a motor base 207, on which a motor 2 209 and a protective cover 211 are fixedly mounted. The motor base 207 is connected to the flip assembly via a rotating shaft 1 208. When no cutting is performed and the cutting angle is adjusted, the angle of the cutting tooth disc 210 relative to the operating table 101 is adjusted via the flip assembly.

[0039] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, when cutting, the motor 209 fixed on the motor base 207 is started, and the cutting tooth disc 210 is driven to rotate by the motor 209, so that the concrete is cut by the cutting tooth disc 210. The function of the protective cover 211 is to protect people from touching the cutting tooth disc 210 and prevent flying waste from causing harm to people. When cutting is not needed, the cutting tooth disc 210 can be retracted by flipping the assembly (as shown in FIG. Figure 4 In addition, when the cutting angle needs to be adjusted, the flip assembly can also adjust the angle of the cutting toothed disc 210 relative to the operating table 101 ( Figure 1 and Figure 2 (All are schematic diagrams of vertical cutting).

[0040] The flip assembly includes an L-shaped frame 201, on which a guide block 202 is provided. Both the L-shaped frame 201 and the guide block 202 are in sliding cooperation with the operating table 101. A motor 203 is fixedly mounted 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 gear 205. The worm gear 205 is connected to the flip frame 206 via a rotating shaft. The flip frame 206 is in rotation cooperation with a rotating shaft 208, and the rotating shaft is rotationally mounted on the L-shaped frame 201.

[0041] like Figure 1 、 Figure 5 、 Figure 6 As shown, when it is necessary to adjust the cutting angle of the cutting tooth disc 210 or retract the cutting tooth disc 210 and the motor 209 to Figure 4 When in the idle state, motor 1 203, which is fixed to L-shaped frame 201, is started, causing worm 1 204, which is fixed to the output shaft of motor 1 203, to rotate. At this time, worm gear 1 205, which meshes with worm 1 204, rotates on L-shaped frame 201 via the rotating shaft, causing the rotating shaft to rotate flip frame 206. Motor base 207, which is connected to flip frame 206, then drives cutting gear disc 210 to rotate a certain angle according to actual needs (flip frame 206, motor base 207, and rotating shaft 1 208 rotate together at this time). In addition, by applying force to motor base 207, motor base 207 can be rotated relative to flip frame 206 via rotating shaft 1 208, thereby adjusting the angle of cutting gear disc 210. In addition, L-shaped frame 201 and guide block 202 can also slide on operating table 101. Of course, by restricting the movement of guide block 202, L-shaped frame 201 and guide block 202 can also be positioned.

[0042] 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 and cut the concrete product.

[0043] The second cutting mechanism 3 also includes a movable plate 301, which is movably mounted on the supporting assembly through a movable module 308, and a motor five is fixedly mounted on the movable plate 301, the output shaft of the motor five is connected to a pulley one 302, and the other two pulley ones 302 are symmetrically arranged at one end of two rotating arms 307, and the other ends of the rotating arms 307 are connected to worm gear two 306, the two worm gear twos 306 are distributed on both sides of the worm two 305, and the worm gear two 306 is engaged with the worm two 305, and the worm two 305 is fixedly mounted on the output shaft of the motor three 304, and the motor three 304 is fixedly mounted on the movable plate 301.

[0044] 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 an existing technology, those skilled in the art can implement it and install the guide rail on the support rod 316 and the electromagnetic slider on the moving plate 301.

[0045] like Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 As shown, when cutting is required by the cutting rope 303, the cutting rope 303 needs to be driven to rotate by the pulley 1 302, so that the concrete is cut by the cutting rope 303. Specifically, the motor 5 fixedly mounted on the movable plate 301 is started to rotate the pulley 1 302 fixed on the output shaft of the motor 5, so that the other two 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 platform 401. According to different needs, the cutting speed needs to be adjusted. When adjusting, start motor three 304 so that the output shaft of motor three 304 drives worm two 305 to rotate, and worm gear two 306 engaged with worm two 305 rotates on the movable plate 301, so that worm gear two 306 drives the rotating arm 307 to rotate. In this way, the distance between pulley one 302 installed on the rotating arm 307 and the conveying platform 401 can be adjusted, that is, the cutting depth is adjusted. At the same time, the cutting rope 303 installed on pulley one 302 can also be replaced according to the cutting depth.

[0046] The supporting assembly includes a third support rod 316, which is connected to the mobile module 308. One end of the third support rod 316 is rotatably mounted 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 slides with the arc groove 314 and the straight groove 315 provided on the operating table 101 through the second rotating shaft 313. The arc groove 314 and the straight groove 315 are smoothly connected. One end of the second positioning rod 312 is rotatably mounted on the first support rod 309. 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 slides with the side of the third support rod 316 away from the mobile plate 301.

[0047] like Figure 1 — Figure 4 、 Figure 7 — Figure 9 As shown, when the support rod 1 309, the support rod 2 310 and the support rod 3 316 are in the open state (as shown in FIG. Figure 1 、 Figure 2 As shown), for the cutting state, the support rod 1 309, the support rod 2 310 and the support rod 3 316 play a supporting role on the movable plate 301. Figure 4When the position of the first and second positioning rods 311 and 312 is reached, the first and second positioning rods 311 and 312 are retracted (when the second and first positioning rods 312 and 311 are in the straight state, the first and second positioning rods 311 and 312 support and position the third support rod 316, so that the third support rod 316 is in a vertical state). Specifically, the second positioning rod 312 is held, and then the first positioning rod 311 is rotated with force so that the end of the first positioning rod 311 that contacts the third support rod 316 in a clockwise direction is flipped to the right side of the second positioning rod 312 (so that the first and second positioning rods 311 and 312 are in the straight state). Figure 9 Then rotate the positioning rod 2 312 to retract the positioning rod 2 312 into the groove provided on the inner wall of the support rod 1 309. Figure 9 (The perspective is based on the rotation of the support rod 316, so that the support rod 316 is retracted into the groove inside the support rod 2 310. Similarly, the support rod 2 310 is rotated to retract the support rod 2 310 into the groove inside the support rod 1 309. After the support rods 2 310 and 316 are completely stored, the rotation shaft 2 313 is pushed upward along the straight groove 315, and then the rotation shaft 2 313 is slid into the arcuate groove 314, so that the support rod 1 309 rotates 90 degrees from the vertical state to the horizontal state. It should be noted that the connection between the support rod 1 309 and the support rod 2 310, and the connection between the support rod 2 310 and the support rod 3 316 are both equipped with damping. That is, the state will not change due to gravity itself, and external force must be applied manually to overcome the damping to change the state.

[0048] The feeding mechanism 4 is mounted on the operating table 101 and includes a conveying platform 401 movably mounted on the operating table 101. The feeding mechanism 4 also includes two symmetrically arranged threaded rods 403, which are rotatably mounted on the operating table 101. The conveying platform 401 is threadedly engaged with the threaded rods 403, and the conveying platform 401 and the operating table 101 are slidably engaged. The conveying platform 401 is provided with a plurality of positioning grooves 402, and a plurality of clamping assemblies are detachably mounted on the positioning grooves 402. The feeding mechanism 4 also includes a motor 410 fixedly mounted on the operating table 101. The output shaft of the motor 410 is connected to a pulley 2 411, and the pulley 2 411 is connected to a belt 412. The belt 412 is further connected to two symmetrically arranged pulleys 2 411. The two pulleys 2 411 located on both sides of the motor 410 are respectively mounted on the two threaded rods 403.

[0049] like Figure 1 — Figure 2 、 Figure 10 、 Figure 11As shown, when cutting a concrete product, the concrete product is placed on the conveyor table 401, and then clamped to the conveyor table 401 by a clamping assembly, and the conveyor table 401 drives the concrete product to the cutting position. Specifically, the motor 410 fixedly mounted on the operating table 101 is started, so that a pulley 2 411 fixed on the output shaft of the motor 410 drives the belt 412 to rotate, thereby causing the other two pulleys 2 411 connected to the belt 412 to rotate. At this time, the threaded rod 403 connected to the pulley 2 411 will rotate, and the conveyor table 401 and the threaded rod 403 are threadedly matched, so that the conveyor table 401 slides along the operating table 101 to the target position.

[0050] The clamping assembly includes a lower plate 407, the width of which is no greater than the width of the positioning groove 402, a cylinder 406 is rotatably mounted on the lower plate 407, the protruding end of the cylinder 406 is connected to the pressure plate 404, a plurality of friction grooves 405 are provided on the side of the pressure plate 404 facing the lower plate 407, an intermediate plate 408 is provided between the pressure plate 404 and the lower plate 407, and bolts 409 are threadedly connected on both sides of the intermediate plate 408.

[0051] like Figure 10 — Figure 12 As shown, when clamping the concrete product, the cylinder 406 is started, so that the extended end of the cylinder 406 drives the pressure plate 404 to move upward, adjusts the height of the pressure plate 404 relative to the concrete product, and finally makes the lower surface of the pressure plate 404 contact the upper surface of the concrete product. The pressure plates 404 in the multiple clamping assemblies complete the clamping of the concrete product. The friction groove 405 provided on the pressure plate 404 is to increase the friction force and improve the stability of the clamping.

[0052] The conveyor 401 is provided with a plurality of positioning grooves 402 so as to be able to adjust the positions of the plurality of clamping assemblies according to the size of the concrete product. Specifically, when the position of the clamping assembly needs to be adjusted, the bolt 409 is first rotated to raise the position of the bolt 409 relative to the lower plate 407, that is, the bolt 409 no longer contacts the conveyor 401, so that the lower plate 407 can be easily rotated relative to the conveyor 401. When the long side of the lower plate 407 rotates to coincide with the long side of the positioning groove 402, the lower plate 407 and the pressure plate 404 can be removed from the positioning groove 402, and then the lower plate 407 can be placed in another target positioning groove 402. The bolt 409 is then screwed downward again so that the end of the bolt 409 away from the pressure plate 404 can be in close contact with the upper surface of the conveyor 401, thereby completing the installation. The width of the lower plate 407 is not greater than the width of the positioning groove 402 to ensure that the lower plate 407 can be taken out from under the conveyor platform 401. The length of the lower plate 407 is not greater than the length of the positioning groove 402 to facilitate the removal or installation of the lower plate 407.
