Description

A concrete block scrap cutting device Technical Field

[0001] This utility model relates to the field of concrete block scrap cutting technology, and more specifically, to a concrete block scrap cutting device. Background Technology

[0002] During the production of concrete blocks, a large amount of scrap material is generated due to process requirements and strict requirements for the dimensional accuracy of the blocks. If these scrap materials are not used properly, they will not only waste resources, but also occupy a lot of space, increase the production costs of enterprises and the environmental burden. At present, some enterprises choose to discard the concrete block scrap materials directly, which is undoubtedly a huge waste of resources. Some enterprises that try to reprocess and utilize the scrap materials face many technical problems.

[0003] Traditional cutting equipment uses conveyor belts to transport concrete block scraps. However, the scraps are prone to shaking and shifting during transport, making it difficult to accurately position them for cutting. This severely affects the cutting accuracy. Furthermore, the cutting process is often cumbersome, requiring frequent manual adjustments to the cutting position and angle, which consumes a lot of time and labor. It is also inconvenient to gather the scraps to a designated location. Therefore, a concrete block scrap cutting device is proposed. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concrete block scrap cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete block scrap cutting device, comprising a workbench, a U-shaped frame fixedly connected to the top of the workbench, a first electric push rod, a purification box, and an air pump fixedly connected to the top of the U-shaped frame, two dust collection boxes fixedly connected to one side of the U-shaped frame, a support frame connected to the output end of the first electric push rod, and multiple limiting wheels fixedly connected to the middle of the support frame, with anti-slip belts fitted on the outer surface of the limiting wheels. Activating the first electric push rod controls the support frame to drive the limiting wheels and anti-slip belts to move downwards, which can squeeze and limit the conveyed block scraps, facilitating cutting.

[0006] The workbench is equipped with a conveyor belt at the top, multiple support rollers in the middle of the conveyor belt, symmetrical limit plates on both sides of the conveyor belt, and symmetrical guide mechanisms on both sides of the top end of the conveyor belt. The conveyor belt can transport the block scraps to one side of the cutting blade, the support rollers can support the block scraps, the limit plates can limit the block scraps, and the guide mechanism can gather the placed block scraps towards the center for easy cutting.

[0007] The bottom of the U-shaped frame has symmetrically arranged limiting grooves on both sides. A threaded rod is provided in the middle of the limiting groove. One end of the threaded rod is connected to a second motor. Support plates are symmetrically arranged on both sides of the support frame. A first motor is fixedly connected to the bottom of one side of the support plate. A cutting blade is connected to the output end of the first motor. An elastic strip is fixedly connected to the bottom of the dust collection box. Starting the first motor controls the rotation of the cutting blade, which can cut the edge scraps of the blocks. By starting the second motor, the threaded rod is controlled to move the support plate, which can adjust the distance between the two cutting blades for convenient cutting. Starting the air pump absorbs the dust generated during cutting through the dust collection box and introduces it into the interior of the purification box, which plays a role in dust removal.

[0008] Preferably, a control panel is provided on one side of the U-shaped frame, the input end of the air pump is connected to the inner cavity of the dust collection box, and the output end of the air pump is connected to the inner cavity of the purification box. The control panel facilitates the control and drive. By starting the air pump, suction can be generated inside the dust collection box to absorb the dust generated by the cutting blade and input it into the purification box for purification.

[0009] Preferably, the bottom opening on one side of the dust collection box corresponds one-to-one with the cutting blade, and the two cutting blades are arranged on opposite sides of the two support plates. The dust generated by the cutting blades can be absorbed by the dust collection box.

[0010] Preferably, the top of the support plate extends into the interior of the limiting slide groove, and a second stabilizing rod is fixedly connected to the middle of the limiting slide groove. The second stabilizing rod and the threaded rod both pass through the middle of the support plate. The two ends of the threaded rod are symmetrical with the threads at corresponding positions on the support plate. The threaded rod is threadedly connected to the support plate. Starting the second motor controls the threaded rod to drive the support plate to move, which can adjust the distance between the two cutting blades.

[0011] Preferably, the cross-sectional shape of the support frame is set to "U" shape, and the top two sides of the support frame are symmetrically fixedly connected with first stabilizing rods. The first stabilizing rods penetrate through the wall of the U-shaped frame and support the limiting wheel and anti-slip belt through the support frame. The stability of the support frame moving up and down is improved by the first stabilizing rods.

[0012] Preferably, the guiding mechanism includes a second electric push rod fixed to one side opposite to the other of the two limiting side plates, and a support rod fixed to one side opposite to the other of the two limiting side plates, the support rod being disposed on the top of the conveyor belt.

[0013] Preferably, one end of the support rod is rotatably connected to a guide plate, and the output end of the second electric push rod is rotatably connected to a limit slider. A limit groove is formed on one side of the guide plate at a position corresponding to the limit slider. The limit slider is set inside the limit groove. When the second electric push rod is activated to push the guide plate, the guide plate can rotate relative to the support rod, thereby adjusting the closest distance between the two guide plates for easy adjustment and use. The guide plate can guide the placed block scraps towards the center, improving the use effect.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention firstly uses a guiding mechanism to gather placed block scraps towards the center via a guide plate. Then, by starting a first motor, the cutting blade rotates to cut the damaged ends of the block scraps. The cutting distance for multiple block scraps is fixed. Furthermore, the anti-slip belt and limit wheels work together to compress the conveyed block scraps, preventing shaking and deviation during cutting and conveying, improving cutting accuracy, and thus improving the dimensional uniformity of the finished product. It eliminates the need for manual adjustment of the cutting position and angle, reducing costs.

[0016] This invention also utilizes an air pump to generate suction at the bottom opening of the dust collection box, which absorbs the dust generated during the cutting process and purifies it by introducing it into the purification box, thus improving the cleanliness of the working environment. Furthermore, by starting the second motor, the two cutting blades can be moved simultaneously in sequence, allowing adjustment of the distance between them and the width of the finished product for easy adjustment. Additionally, by starting the first electric push rod, the support frame is controlled to move up and down, which facilitates the compression and limiting of block scraps of different heights without affecting the conveying and movement of the block scraps.

[0017] In summary, through the interaction of the above-mentioned multiple functions, the placed block scraps can be gathered towards the center, and shaking or deviation during cutting and conveying can be avoided, improving cutting accuracy and thus improving the dimensional uniformity of the finished product. There is no need for manual adjustment of the cutting position and angle, reducing costs. Attached Figure Description

Activating the first electric push rod 3 controls the support frame 4 to drive the limiting wheels 5 and anti-slip belts 6 to move downwards, which can squeeze and limit the conveyed block scraps, making them convenient for cutting.

[0026] The top of the workbench 1 is equipped with a conveyor belt 13, and multiple support rollers 14 are provided in the middle of the conveyor belt 13. Limiting side plates 15 are symmetrically provided on both sides of the conveyor belt 13. Guiding mechanisms are symmetrically provided on both sides of the top end of the conveyor belt 13.

The limiting side plates 15 can limit the block scraps. The guiding mechanism can gather the placed block scraps towards the center for easy cutting.

[0027] The bottom of the U-shaped frame 2 has symmetrically arranged limiting grooves 7 on both sides. A threaded rod 8 is provided in the middle of the limiting groove 7. One end of the threaded rod 8 is connected to a second motor 12. Support plates 9 are symmetrically arranged on both sides of the support frame 4. A first motor 10 is fixedly connected to the bottom of one side of the support plate 9. The output end of the first motor 10 is connected to a cutting blade 11. An elastic strip 20 is fixedly connected to the bottom of the dust collection box 19. Starting the first motor 10 controls the cutting blade 11 to rotate, which can cut the edge scraps of the blocks. By starting the second motor 12, the threaded rod 8 is controlled to move the support plate 9, which can adjust the distance between the two cutting blades 11 for convenient cutting. Starting the air pump 22 absorbs the dust generated during cutting through the dust collection box 19 and inputs it into the purification box 21 to remove dust.

[0028] As shown in Figures 1-5, a control panel 23 is provided on one side of the U-shaped frame 2. The input end of the air pump 22 is connected to the inner cavity of the dust collection box 19, and the output end of the air pump 22 is connected to the inner cavity of the purification box 21. The bottom opening on one side of the dust collection box 19 corresponds one-to-one with the cutting blade 11. The two cutting blades 11 are set on opposite sides of the two support plates 9. The top of the support plate 9 extends into the interior of the limiting slide groove 7. A second stabilizing rod 25 is fixedly connected to the middle of the limiting slide groove 7. The second stabilizing rod 25 and the threaded rod 8 both pass through the middle of the support plate 9. The two ends of the threaded rod 8 are symmetrical with the threads at the corresponding positions of the support plate 9. The threaded rod 8 is threadedly connected to the support plate 9. The cross-sectional shape of the support frame 4 is designed as follows: The support frame 4 is shaped like a "U". The top two sides of the support frame 4 are symmetrically fixed with first stabilizing rods 24. The first stabilizing rods 24 penetrate the wall of the U-shaped frame 2. The control panel 23 can be used to control the drive. By starting the air pump 22, the suction inside the dust collection box 19 can be generated to absorb the dust generated by the cutting blade 11 and input it into the purification box 21 for purification. The dust generated by the cutting blade 11 can be absorbed by the dust collection box 19. The second motor 12 is started to control the threaded rod 8 to drive the support plate 9 to move. The distance between the two cutting blades 11 can be adjusted. The support frame 4 supports the limit wheel 5 and the anti-slip belt 6. The first stabilizing rod 24 improves the stability of the support frame 4 when moving up and down.

[0029] As shown in Figures 1, 3, and 4, the guiding mechanism includes a second electric push rod 18 fixed to one side of the two limiting side plates 15 facing away from each other, and a support rod 16 fixed to one side of the two limiting side plates 15 facing each other. The support rod 16 is set on the top of the conveyor belt 13, and a guide plate 17 is rotatably connected to one end of the support rod 16. A limiting slider is rotatably connected to the output end of the second electric push rod 18. A limiting groove is opened on one side of the guide plate 17 at a position corresponding to the limiting slider. The limiting slider is set inside the limiting groove. When the second electric push rod 18 is activated to push the guide plate 17, the guide plate 17 can rotate relative to the support rod 16, thereby adjusting the closest distance between the two guide plates 17 for convenient adjustment and use. The guide plate 17 can guide the placed block scraps towards the center, improving the use effect.

[0030] The working principle of this utility model is as follows: When in use, the block scraps are placed on the top of the conveyor belt 13 near the guide plate 17. The conveyor belt 13 is started to control the block scraps to be transported to the other end. At the same time, the guide plate 17 gathers the block scraps directly below the anti-slip belt 6. When the block scraps move to the bottom of the anti-slip belt 6, the anti-slip belt 6 and the conveyor belt 13 squeeze the block scraps, which can achieve the fixed transport of the block scraps.

[0031] When the block scraps are in contact with the cutting blade 11, the first motor 10 is started to control the cutting blade 11 to rotate. The block scraps can be cut by the cutting blade 11. At the same time as cutting, the air pump 22 is started to generate suction at the bottom of the dust collection box 19, which can absorb the dust generated by the cutting blade 11 during cutting and achieve the function of dust removal.

[0032] Before processing, the first electric push rod 3 can be activated to control the support frame 4 to drive the limit wheel 5 and the anti-slip belt 6 to move up and down according to the height of the block scrap. This controls the distance between the anti-slip belt 6 and the conveyor belt 13 to be the same as the height of the block scrap, so that the block scrap is squeezed and limited when it moves to the bottom of the anti-slip belt 6.

[0033] Simultaneously, the second motor 12 can be activated to control the support plate 9 to drive the first motor 10 and the cutting blade 11 to move, thereby adjusting the distance between the two cutting blades 11 and facilitating the adjustment of the size of the finished product after cutting.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
