Description

Technical Field

[0001] This invention relates to the field of precast concrete components, and in particular to a method and equipment for manufacturing precast concrete components. Background Technology

[0002] Precast concrete components are building components made in a factory using concrete as the basic material. They include beams, slabs, columns, blocks, and building decoration accessories. Generally, the size of concrete blocks is fixed. However, the length and height of building walls are often not integer multiples of the standard block size. Therefore, it is necessary to cut the blocks to obtain smaller non-standard sizes for filling positions such as wall ends, corners, and sides of door and window openings. This ensures the flatness and verticality of the wall construction and avoids excessively large or small gaps in the masonry due to size discrepancies.

[0003] Since the non-standard sized blocks required for each layer of building walls are all the same, it is necessary to cut the blocks in batches during actual use. However, most existing cutting equipment is operated manually to cut individual blocks, which cannot form continuous batch cutting and is also prone to danger. Summary of the Invention

[0004] This invention provides a precast concrete component manufacturing equipment that can perform continuous batch cutting, thus avoiding danger.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A precast concrete component manufacturing equipment includes a support platform, a cutting mechanism, and a conveying mechanism. The conveying mechanism includes conveyor frames symmetrically arranged at the left and right ends of the support platform. Conveyor wheels rotate vertically at both ends of the two conveyor frames. Conveyor belts are fitted onto the two conveyor wheels on the same conveyor frame. The precast concrete components can be conveyed backward on the support platform by the two opposing conveyor belts, and the precast concrete components are cut by the cutting mechanism when passing through it.

[0007] The cutting mechanism includes an L-shaped plate fixed to the right end of the middle of the support platform. The L-shaped plate has a cutting frame that slides up and down at its upper limit. A power shaft rotates on the cutting frame. A cutting disc is installed at the end of the power shaft. A cutting hole is provided at the support platform below the cutting disc.

[0008] An adjusting screw I is threadedly connected to the L-shaped plate, and the lower end of the adjusting screw I is rotatably connected to the cutting frame.

[0009] The cutting disc is covered by a protective cover, and an air suction pipe is provided at the upper end of the protective cover.

[0010] The lower end of the protective cover is slidably connected to a pressure plate for lifting and limiting. The front end of the pressure plate is inclined upward with a slope plate. A spring I is provided between the pressure plate and the protective cover.

[0011] The supporting platform is equipped with horizontal sliding rods at both the front and rear ends. The front and rear ends of the two conveyor frames slide on the two horizontal sliding rods respectively. The left and right ends of the supporting platform are equipped with adjusting screws II, and the two adjusting screws II are threadedly connected to the two conveyor frames respectively.

[0012] Multiple tensioning frames slide evenly through the conveyor frame. Each tensioning frame has a rotating roller at its inner end. A spring II is provided between each tensioning frame and the conveyor frame to push the conveyor belt inward.

[0013] The support platform has a placement plate at the front center, and two side baffles are symmetrically provided at the front ends of the two conveyor frames. The upper ends of the two conveyor wheels at the front end are provided with conical wheels. The placement plate includes a flat strip extending forward at the front end of the support platform, a support plate extending downward from the front end of the flat strip, and a stop plate vertically fixed to the front end of the support plate.

[0014] The support platform is equipped with support legs at all four corners. The two support legs at the front end have telescopic leg frames that slide and limit the lifting. The telescopic leg frames are threadedly connected to adjusting screws III, which are rotatably connected to the support platform.

[0015] A method using the aforementioned precast concrete component manufacturing equipment includes:

[0016] S1. Start the cutting mechanism and the conveying mechanism to make the two conveyor belts rotate in opposite directions on the support platform;

[0017] S2. Place the precast concrete components to be cut sequentially at the front end of the support platform between the two conveyor belts;

[0018] S3. Two opposing conveyor belts can push the precast concrete components to be cut to slide backward in sequence, and the cutting is completed after passing the cutting mechanism.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. By using two opposing rotating conveyor belts, precast concrete components can be transported sequentially backward on the support platform, and when passing through the cutting mechanism, the precast concrete components are cut sequentially, thus forming a batch of continuous cutting and avoiding danger.

[0021] 2. By setting two adjusting screws II, the positions of the two conveyor frames can be controlled separately, so that the equipment can adapt to the conveying of blocks of different widths. At the same time, the position of the cutting disc corresponding to the precast concrete component can be adjusted, so that the equipment can complete the continuous cutting of blocks of different sizes.

[0022] 3. The combination of the placement plate, side baffle, and cone wheel facilitates the placement of blocks between two conveyor belts. Attached Figure Description

[0033] like Figure 1-7 As shown, a detailed description of a precast concrete component manufacturing equipment is provided:

[0034] A precast concrete component manufacturing equipment includes a support platform 101, a cutting mechanism, and a conveying mechanism. The conveying mechanism includes conveyor frames 201 symmetrically arranged at the left and right ends of the support platform 101. Conveyor wheels 202 rotate vertically at both ends of the two conveyor frames 201. Conveyor belts 203 are fitted onto the two conveyor wheels 202 on the same conveyor frame 201. The precast concrete components can be conveyed backward on the support platform 101 by the two opposing rotating conveyor belts 203, and the precast concrete components are cut when passing through the cutting mechanism.

[0035] During cutting, the cutting mechanism and the conveying mechanism are activated, causing the two conveyor belts 203 to rotate in opposite directions on the support platform 101. Then, the precast concrete components to be cut are placed sequentially at the front end of the support platform 101 between the two conveyor belts 203. The two opposing conveyor belts 203 will push the precast concrete components to be cut to slide backward on the support platform 101 sequentially, so that the precast concrete components pass through the cutting mechanism in sequence, and the cutting is completed.

[0036] Further:

[0037] The cutting mechanism includes an L-shaped plate 103 fixed to the right end of the middle of the support platform 101. A cutting frame 401 is slidably raised and lowered on the L-shaped plate 103. A power shaft 402 rotates on the cutting frame 401. A cutting disc 403 is installed at the end of the power shaft 402. A cutting hole 102 is provided on the support platform 101 below the cutting disc 403.

[0038] An adjusting screw I 405 is threaded onto the L-shaped plate 103, and the lower end of the adjusting screw I 405 is rotatably connected to the cutting frame 401.

[0039] By installing a power motor at the outer end of the cutting frame 401, the power shaft 402 is driven to rotate at high speed, thereby driving the cutting disc 403 to rotate and rotate the adjusting screw I 405. By adjusting the threaded engagement between the adjusting screw I 405 and the L-shaped plate 103, the adjusting screw I 405 moves up and down on the L-shaped plate 103, thereby driving the cutting frame 401 to move up and down, adjusting the height of the cutting disc 403, and thus cutting the blocks that have moved to the cutting disc 403.

[0040] Further:

[0041] The cutting disc 403 is covered by a protective cover 404, and the upper end of the protective cover 404 is provided with an air suction pipe.

[0042] Connect the suction pipe to the suction system. During cutting, low-pressure suction is applied at the lower port of the cover 404 to draw the dust generated during cutting into the cover 404 and then into the suction system, thus preventing cutting dust from polluting the environment.

[0043] Further:

[0044] The lower end of the protective cover 404 is slidably connected to a pressure plate 406 for lifting and limiting. The front end of the pressure plate 406 is inclined with a slope plate 408. A spring I 407 is provided between the pressure plate 406 and the protective cover 404.

[0045] During cutting, since the upper end of the block is not limited during transportation, the block may detach from the support platform 101 during cutting, making stable cutting impossible. Therefore, a clamping plate 406 is set up, and the spring force of spring I 407 makes the clamping plate 406 press against the block being cut to ensure the stability of the block.

[0046] Meanwhile, through the setting of the inclined plate 408, during the process of the block moving backward, it first contacts the inclined plate 408, and through the inclined surface of the inclined plate 408, the inclined plate 408 drives the pressing plate 406 to rise, and then the pressing plate 406 slides to the upper end of the block to complete the pressing.

[0047] Based on the above embodiments:

[0048] The supporting platform 101 is provided with horizontal slide bars 104 at both the front and rear ends. The front and rear ends of the two conveyor frames 201 slide on the two horizontal slide bars 104 respectively. The supporting platform 101 is provided with adjusting screws II 204 at both the left and right ends. The two adjusting screws II 204 are threadedly connected to the two conveyor frames 201 respectively.

[0049] Rotating the adjusting screw II 204 allows the conveyor frame 201 to move laterally through the threaded engagement between the adjusting screw II 204 and the conveyor frame 201, thereby adjusting the width between the two conveyor belts 203, making it easier for the equipment to adapt to the cutting of precast concrete components of different widths.

[0050] Furthermore, by setting two adjusting screws II 204, the positions of the two conveyor frames 201 can be controlled separately. Since the cutting disc 403 remains in the middle position, by controlling the positions of the two conveyor frames 201, the position of the precast concrete component corresponding to the cutting disc 403 can also be adjusted, which makes it easier for the equipment to complete the continuous cutting of blocks of different sizes.

[0051] Based on the above embodiments:

[0052] Multiple tensioning frames 301 are evenly slidably passed through the conveyor frame 201. Rollers 302 rotate at the inner ends of the multiple tensioning frames 301. A spring II 303 is provided between each tensioning frame 301 and the conveyor frame 201, so that the rollers 302 push the conveyor belt 203 inward.

[0053] When the two conveyor belts 203 push the block backward by friction and complete the cutting, due to the existence of the cutting size, after the block is cut into two pieces by the cutting disc 403, its overall width becomes narrower. This causes gaps to appear between the two ends of the two smaller blocks and the two conveyor belts 203, which makes it impossible for the conveyor belts 203 to transport the two smaller blocks by friction. Therefore, multiple tensioning frames 301 are set up so that the elastic force of the spring II 303 pushes the tensioning frames 301, causing the rollers 302 to push the conveyor belts 203 inward, ensuring that the conveyor belts 203 clamp the smaller blocks, thereby ensuring the continuous transport of the two smaller blocks.

[0054] Based on the above embodiments:

[0055] The support platform 101 has a placement plate 108 at the front center, and two side baffles 205 are symmetrically provided at the front ends of the two conveyor frames 201. The upper ends of the two conveyor wheels 202 at the front end are each provided with a conical wheel 206. The placement plate 108 includes a flat strip 108a extending forward from the front end of the support platform 101, a pallet strip 108b extending downward from the front end of the flat strip 108a, and a head plate 108c vertically fixed to the front end of the pallet strip 108b.

[0056] Since the two conveyor belts 203 need to be tightly fitted to both sides of the block to complete the conveying of the block, it is difficult to place the block directly between the two conveyor belts 203 at the front end. Therefore, a placement plate 108 is set in front of the two conveyor belts 203. When placing the block, the block is placed vertically on the inclined support strip 108b by the blocking of the two side baffles 205. Then, the block is pushed backward, causing it to tilt backward onto the inclined support strip 108b. Due to the presence of the end plate 108c, when the block tilts backward, its upper part will fall between the two conical rollers 206, and then be subjected to the two... Guided by the conical surface of the cone wheel 206 and its own weight, the upper end of the block falls between the two conveyor belts 203. Affected by the backward movement of the two conveyor belts 203, the block in this state is pulled backward with the conveyor belts 203, so that the block is completely placed between the two conveyor belts 203, thus completing the placement of the block between the two conveyor belts 203. Even if the front end of the block cannot fall onto the support platform 101 as the conveyor belts 203 move, it will be pressed down when passing the inclined plate 408, or it will remain in this state to complete the cutting; thereby achieving the purpose of facilitating the placement of the block between the two conveyor belts 203.

[0057] Based on the above embodiments:

[0058] The support platform 101 is provided with support legs 105 at each of its four corners. The two support legs 105 at the front end are equipped with telescopic leg frames 106 that slide and limit the lifting. The telescopic leg frames 106 are threadedly connected to the adjusting screws III 107, which are rotatably connected to the support platform 101.

[0059] Rotating the adjusting screw III107 will cause the telescopic leg 106 to move along the adjusting screw III107 through the threaded engagement between the adjusting screw III107 and the telescopic leg 106, forming an extension inside the front support leg 105, so that the supporting platform 101 is in a front-high and rear-low state, which facilitates the placement of blocks and the transport of blocks to move backward on the supporting platform 101.
