Description

Technical Field

[0001] This application relates to the technical field of construction formwork cleaning equipment, and particularly to a device for removing waste materials from construction formwork. Background Art

[0002] A construction formwork is a temporary and precisely shaped standard support component for the poured concrete. During the construction of a building project, the formwork needs to be disassembled and the end faces of the construction formwork need to be cleaned to remove the residual concrete waste on the end faces of the formwork, so as to avoid the influence of the residual waste on the fitting effect during the reuse of the construction formwork and realize the recycling of the construction formwork.

[0003] However, the existing cleaning of the formwork end faces relies on manual operation. Workers need to use scrapers to remove the waste materials on the construction formwork. It is difficult to control the force of shoveling materials during the cleaning process. When manually scraping forcefully, it is easy to damage the end face of the formwork with the scraper, affecting the flatness of the formwork end face, and even causing pits on the formwork end face. Moreover, the cleaning process is time-consuming and laborious, reducing the cleaning efficiency. Summary of the Invention

[0004] This application provides a device for removing waste materials from construction formwork, which has the advantage of automatically cleaning the end faces on both sides of the formwork, so as to solve the problem that it is difficult to control the force when manually scraping the end face of the construction formwork, which easily leads to uncertain scraping depths.

[0005] To achieve the above object, this application adopts the following technical solution: A device for removing waste materials from construction formwork includes a housing. Driving mechanisms are arranged on both sides of the housing. The driving mechanisms are drivingly connected to two conveyor belts. Two cleaning rollers are rotatably arranged at a position near the midpoint inside the housing. Two second motors for driving the cleaning rollers to rotate are fixedly arranged on the top of the housing; The driving mechanism can drive the corresponding conveyor belt to rotate in a cycle, so that the conveyor belt cooperates to convey the construction formwork, and the construction formwork is conveyed past the rotating cleaning rollers. The two cleaning rollers are used to clean the two end faces of the construction formwork respectively.

[0006] Further, the direction of the force exerted by the cleaning roller on the construction formwork is opposite to the direction of the conveyance of the construction formwork. A fixed pipe is fixedly arranged at a position near the bottom of the housing. The fixed pipe is communicated with a suction assembly through a pipeline. A connecting pipe is rotatably connected to the top of the fixed pipe. A fixed frame is arranged inside the cleaning roller. A plurality of telescopic mechanisms are arranged on the outer side of the fixed frame; A plurality of fixing sleeves adapted to the sliding rods are fixedly arranged on the inner wall of the cleaning roller. A plurality of through grooves are formed in the roller body of the cleaning roller. A connecting groove is formed in the outer wall of the fixing sleeve. The telescopic mechanism can adjust the opening degree of the corresponding connecting groove according to the contact state between the cleaning roller and the construction formwork. When the position of the connecting groove corresponds to the position of the construction formwork, the telescopic mechanism adjusts the connecting groove to open.

[0007] Further, the telescopic mechanism includes a sliding rod, which is T-shaped and slidably connected to the fixed frame. A convex block is fixedly arranged at a position near the midpoint of the rod body of the sliding rod. An adjusting spring is movably sleeved outside the sliding rod. A sliding sleeve for adjusting the opening degree of the connecting groove is slidably connected to the outside of the fixed sleeve. A limiting groove is formed inside the sliding sleeve. A scraping plate is fixedly connected to one side of the sliding sleeve.

[0008] Further, a support rod is fixedly connected to one side of the scraping plate. When the cleaning roller rotates, the scraping plate contacts the building formwork prior to the corresponding support rod. The through groove is adapted to the scraping plate and the support rod, and there is a passage for air to pass through between them.

[0009] Further, end plates are fixedly arranged at the top and bottom inside the cleaning roller. A support frame is fixedly arranged between the two end plates. A flexible filter element is fixedly arranged between the two end plates. The side wall of the filter element is formed by connecting a plurality of folds end to end. A support plate for driving the folds to open is fixedly connected to one side of the sliding rod. Two collecting bins are fixedly connected to the bottom of the cleaning roller. A discharge groove for communicating with the collecting bins is formed at the bottom of the cleaning roller. The fixed frame is fixedly connected to the end plate.

[0010] Further, the number of sliding rods corresponding to a single telescopic mechanism is set to be several. The several sliding rods are arranged at equal intervals along the axial direction of the cleaning roller. The lengths of adjacent scraping plates corresponding to a single telescopic mechanism are different in the radial direction.

[0011] Further, the lengths of the support rods corresponding to adjacent scraping plates corresponding to a single telescopic mechanism are different in the circumferential direction.

[0012] Further, the driving mechanism includes several driving rollers and second transmission wheels. The driving rollers are in transmission connection with the corresponding conveyor belts. The driving rollers are rotatably connected to the housing. A first transmission wheel is coaxially connected to the top of the driving roller. The second transmission wheel is in transmission connection with the corresponding first transmission wheel. The corresponding two first transmission wheels are in transmission connection through a transmission belt. The corresponding two second transmission wheels are in transmission connection through a transmission belt. A first motor is arranged on one side of the housing. The output end of the first motor is in transmission connection with the corresponding first transmission wheel.

[0013] Further, several guide rollers are rotatably arranged on one side of the housing. The several guide rollers are vertically arranged in a V shape. A collecting box is fixedly arranged at the bottom of the housing. A balance spring is arranged on one side of the sliding sleeve.

[0014] Furthermore, a pressing mechanism is provided on one side of the housing. The pressing mechanism includes a fixed seat. A moving plate is slidably clamped on one side of the fixed seat. A pressing roller is rotatably arranged on one side of the moving plate. One side of the moving plate is fixedly connected with a pressing spring, and one end of the pressing spring is fixedly connected with the fixed seat.

[0015] The beneficial effects of the present invention are as follows: 1. For a construction formwork waste removal device provided in this application, the driving mechanism drives the corresponding conveyor belt to rotate, so that the conveyor belt drives the construction formwork with waste to be removed to move, and the construction formwork passes through the rotating cleaning rollers. The roller surfaces of the two cleaning rollers rotate and respectively contact the two end faces of the construction formwork, continuously removing the concrete waste on the end faces of the construction formwork, thereby ensuring the flatness of the end face of the construction formwork after waste removal while improving the removal efficiency.

[0016] 2. For a construction formwork waste removal device provided in this application, the adjusting spring drives the convex block to move, and in cooperation with the reaction force of the scraper on the construction formwork, the position where the sliding sleeve clamps the filter material with the support plate is adjusted. When the cleaning roller rotates, several scrapers respectively rotate to contact the construction formwork. While scraping the concrete waste, they contract into the through groove of the cleaning roller, driving the sliding sleeve to move and causing partial contraction and shaking of the filter material. On the one hand, through the suction effect, the generated smoke and dust are absorbed into the cleaning roller, and the concrete dust is filtered out by the filter material, which is convenient for subsequent treatment, reduces the generation of dust, and ensures a good working environment for the operator. On the other hand, through the shaking of the flexible filter material, the attached waste is shaken off, enabling the continuous regeneration of the filter material and ensuring the effect of the suction function.

Specific embodiments

[0019] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1, as Figures 1-5 and Figures 7-9, a device for removing waste from building construction templates, including a housing 1. Driving mechanisms 7 are provided on both sides of the housing 1. The driving mechanisms 7 are drivingly connected to two conveyor belts 2. The two conveyor belts 2 corresponding to the driving mechanisms 7 are respectively located on both sides of the housing 1. Specifically, the driving mechanism 7 includes a number of driving rollers 703 and second transmission wheels 702. The number of driving rollers 703 corresponding to a single driving mechanism 7 is set to a number. The driving rollers 703 are arranged in parallel between them. A single conveyor belt 2 corresponds to two driving rollers 703. The driving rollers 703 are drivingly connected to the corresponding conveyor belts 2. The driving rollers 703 are rotatably connected to the housing 1 through a rotating shaft. The top of the driving roller 703 is drivingly connected through a rotating shaft in a coaxial manner with a first transmission wheel 701 for driving the driving roller 703 to rotate. The second transmission wheels 702 are respectively drivingly connected to the corresponding first transmission wheels 701 through a rotating shaft in a coaxial manner.

[0021] The second transmission wheels 702 are used to drive the corresponding first transmission wheels 701 to rotate. The two first transmission wheels 701 corresponding to the conveyor belt 2 are drivingly connected through a transmission belt. The two second transmission wheels 702 corresponding to a single driving mechanism 7 are drivingly connected through a transmission belt. A channel for conveying building templates is formed between the two conveyor belts 2 located on the same side of the housing 1. The bottom surface of the conveyor belt 2 is flush with the bottom surface inside the housing 1. A first motor 704 is provided on one side of the housing 1. The output end of the first motor 704 is drivingly connected to the corresponding first transmission wheel 701.

[0022] During use, the first motors 704 corresponding to the two driving mechanisms 7 rotate, driving the corresponding first transmission wheels 701 to rotate. The first transmission wheels 701 drive the first transmission wheels 701 on one side of the conveyor belt 2 through a transmission belt, thereby driving the corresponding conveyor belt 2 to rotate in a cycle. At the same time, the first transmission wheels 701 drive the corresponding second transmission wheels 702 to rotate. The second transmission wheels 702 drive the second transmission wheels 702 corresponding to the conveyor belt 2 on the other side of the housing 1 through a transmission belt, cooperating with the corresponding first transmission wheels 701 to make the two conveyor belts 2 corresponding to a single driving mechanism 7 rotate synchronously. Different conveyor belts 2 drive the building templates to move in the same direction. When performing the single-sided building template removal operation, only a single first motor 704 operates.

[0023] On one side of the housing 1, a number of guide rollers 3 are rotatably arranged. The number of guide rollers 3 is vertically arranged in a V shape, and the opening of the V shape faces the conveyor belt 2. When feeding the building formwork to be removed, the guide rollers 3 are used to guide one side plate body of the vertical building formwork into the conveying channel formed by the conveyor belt 2. The distance between the two conveyor belts 2 on the side close to the guide rollers 3 is adapted to the thickness of the building formwork to be removed, and the distance between the two conveyor belts 2 on the side away from the guide rollers 3 is adapted to the thickness of the plate body of the building formwork after cleaning. At the midpoint position inside the housing 1, two cleaning rollers 4 are rotatably arranged. The axis of the cleaning roller 4 is vertically arranged, and the distance between the cleaning rollers 4 is adapted to the thickness of the plate body of the modeling formwork. At the midpoint position on the top of the housing 1, two second motors 28 are fixedly arranged. The output end of the second motor 28 is in transmission connection with the corresponding cleaning roller 4. The second motor 28 is used to drive the corresponding cleaning roller 4 to rotate, and the direction of the force of the cleaning roller 4 on the building formwork is opposite to the direction of the movement of the building formwork driven by the conveyor belt 2.

[0024] During use, place the modeling formwork on one side of the housing 1 and push the modeling formwork between the guide rollers 3 until it is fed between the conveyor belts 2. The driving mechanism 7 drives the conveyor belt 2 to rotate. The belt surface of the conveyor belt 2 contacts the end face of the building formwork and drives the building formwork to move. During the movement of the building formwork, it contacts at least two conveyor belts 2. The modeling formwork is driven to pass between the two cleaning rollers 4. The second motor 28 drives the cleaning roller 4 to rotate. The cleaning roller 4 contacts the end face of the building formwork, and the waste attached to the end face of the building formwork is removed by grinding. Thus, it is possible to continuously clean the two end faces of the building formwork fed between the conveyor belts 2 synchronously. Compared with manually cleaning the two end faces of the modeling formwork in turn by flipping with a scraper, the cleaning efficiency is improved, and the flatness after the end face is cleaned is ensured.

[0025] During the process of removing the building formwork, some waste is likely to generate smoke and dust under the action of the cleaning roller. The smoke and dust are likely to adhere to the end face of the cleaned building formwork, still affecting the spraying of the release agent when the formwork is reused, and affecting the health of the operators.

[0026] At the bottom position of the housing 1, a fixed pipe 6 is fixedly arranged. The fixed pipe 6 is communicated with the suction assembly through a pipeline. The suction assembly can be set as a blower. The top of the fixed pipe 6 is rotatably connected with a connecting pipe 5. A rotating sealing mechanism is arranged between the connecting pipe 5 and the fixed pipe 6. The rotating sealing mechanism can be set as a mechanical sealing assembly. Inside the cleaning roller 4, a fixed frame 21 is arranged. The relative position between the fixed frame 21 and the cleaning roller 4 is fixed. A number of telescopic mechanisms are arranged on the outer side of the fixed frame 21. The telescopic mechanism includes a sliding rod 22. The number of telescopic mechanisms is annularly arranged on the outer side of the fixed frame 21. The sliding rod 22 is T-shaped and slidably connected with the fixed frame 21. The sliding rod 22 can slide horizontally without detaching from the fixed frame 21. A convex block 23 is fixedly arranged at the midpoint position of the rod body of the sliding rod 22.

[0027] An adjusting spring 24 is movably sleeved on the outer side of the sliding rod 22. The adjusting spring 24 is used to push the convex block 23 away from the fixing frame 21. A plurality of fixing sleeves 11 with the same number as the sliding rod 22 are fixedly arranged on the inner wall of the cleaning roller 4. A plurality of through grooves 10 are formed in the roller body of the cleaning roller 4. The number and position of the through grooves 10 are adapted to the number and position of the fixing sleeves 11. The fixing sleeves 11 communicate with the through grooves 10. Refer to Figure 8 , a connecting groove 12 is formed on the outer wall of the fixing sleeve 11. The number of the connecting grooves 12 is at least one. The connecting groove 12 cooperates with the through groove 10 to communicate the inner and outer sides of the cleaning roller 4. A sliding sleeve 15 is slidably connected to the outer side of the fixing sleeve 11. A limiting groove 16 is formed on the inner side of the sliding sleeve 15. One side plate body of the fixing sleeve 11 is slidably connected to the limiting groove 16. The limiting groove 16 is used to limit the sliding range of the sliding sleeve 15 relative to the fixing sleeve 11 and guide the sliding of the sliding sleeve 15 to prevent the sliding sleeve 15 from detaching from the fixing sleeve 11. The sliding sleeve 15 is used to adjust the opening degree of the connecting groove 12.

[0028] The sliding sleeve 15 can slide to be sleeved with the plate body of the fixing sleeve 11. At this time, the connecting groove 12 is located inside the sliding sleeve 15, and the opening degree is relatively reduced to the minimum. The sliding rod 22 is used to drive the sliding sleeve 15 to slide. One side of the sliding sleeve 15 is fixedly connected with a scraping plate 13. Refer to Figure 7 , one side of the scraping plate 13 is fixedly connected with a support rod 14. The scraping plate 13 is used to act on the building formwork, scrape the waste of the building formwork and drive the sliding sleeve 15 to move at the same time. During the rotation of the cleaning roller 4, the corresponding scraping plate 13 contacts the building formwork before the support rod 14. The support rod 14 can also be set as a plate shape. The support rod 14 is used to limit the rebound of the scraping plate 13. The size and shape of the through groove 10 are adapted to the scraping plate 13 and the support rod 14 and leave a passage for air to pass through. The scraping plate 13 and the support rod 14 can contract into the through groove 10. The outer wall of the connecting pipe 5 is fixedly connected with the cleaning roller 4.

[0029] When the cleaning roller 4 rotates and contacts the end face of the building formwork, different scraping plates 13 on the circumference of the cleaning roller 4 cycle to contact the end face of the building formwork, cooperate with the waste broken on the roller surface of the cleaning roller 4. At the same time, the suction assembly acts, generating a negative air pressure relative to the outside of the cleaning roller 4 inside the cleaning roller 4 through the fixed pipe 6 and the connecting pipe 5. The adjusting spring 24 overcomes the negative pressure to push the convex block 23, so that the convex block 23 drives the sliding rod 22 to move. The sliding rod 22 drives the sliding sleeve 15 to move towards the outer wall of the cleaning roller 4 in a transmission manner. The sliding sleeve 15 reduces the opening degree of the connecting groove 12 to a rated low value.

[0030] At least one scraping plate 13 or support rod 14 is in contact with the building formwork. At this time, the building formwork drives the support rod 14 or the scraping plate 13 to contract towards the inside of the cleaning roller 4. The support rod 14 drives the corresponding sliding sleeve 15 to move, increasing the opening degree of the connecting groove 12, so that the air outside the cleaning roller 4 is extracted from the area where the cleaning roller 4 contacts the building formwork, through the through groove 10, the connecting groove 12, the connecting pipe 5 and the fixed pipe 6, thereby sucking out the soot. The telescopic mechanism that is not in contact with the building formwork keeps the corresponding connecting groove 12 in the smallest opening state. The air negative pressure is concentrated on the parts of the cleaning roller 4, the scraping plate 13 and the support rod 14 that act on the building formwork, ensuring the suction efficiency, reducing the possibility of dust flying, avoiding excessive air without soot being sucked out through the through groove 10, and reducing energy waste.

[0031] Embodiment 2, as Figures 1-9 and Figure 11 , on the basis of Embodiment 1, end plates 19 are fixedly arranged at the top and bottom inside the cleaning roller 4. A support frame 20 is fixedly arranged between the two end plates 19. A filter element 18 is fixedly arranged between the two end plates 19. The filter element 18 is set as a flexible structure. The filter element 18 is sleeved outside the support frame 20. The support frame 20 is used to support the filter element 18. The side wall of the filter element 18 is formed by connecting the heads and tails of several folds. The position of the sliding rod 22 corresponds to the position of the folds. A support plate 8 for driving the folds to open is fixedly connected to one side of the sliding rod 22.

[0032] The sliding sleeve 15 and the support plate 8 are respectively located inside and outside the corresponding folds. The connecting pipe 5 is fixedly connected to the end plate 19. The connecting pipe 5 is communicated with the inside of the filter element 18. The filter element 18 is used to filter the sucked air. Refer to Figure 3 , two collecting bins 26 are fixedly connected to the bottom of the cleaning roller 4. The cross section of the collecting bin 26 is in an arc shape. The collecting bin 26 is fixedly connected to the cleaning roller 4 in a detachable manner. A discharge slot 25 for communicating with the collecting bin 26 is opened at the bottom of the cleaning roller 4. The fixing frame 21 is fixedly connected to the end plate 19. A collecting box 27 is fixedly arranged at the bottom of the housing 1. The collecting box 27 is used to collect large waste materials.

[0033] When the soot-containing air entering the inside of the cleaning roller 4 passes through the filter element 18, the waste soot is filtered out by the filter element 18 and stays on the outer wall of the filter element 18 or enters the collecting bin 26 through the discharge slot 25 under the action of gravity. The waste materials in the collecting bin 26 are taken out and cleaned regularly. When the scraping plate 13 contracts towards the inside of the cleaning roller 4, the scraping plate 13 drives the sliding sleeve 15 to approach the fixing frame 21. The sliding sleeve 15 drives the corresponding folds to contract and vibrate, shaking off the accumulated soot attached to the outer wall of the filter element 18, ensuring the continuous regeneration of the filter element 18, thereby separating the soot from the air, facilitating the subsequent centralized treatment of the waste materials, and further ensuring the suction efficiency.

[0034] Embodiment 3, as Figures 1-10, on the basis of the second embodiment, the number of sliding rods 22 corresponding to a single telescopic mechanism is set to several, and the several sliding rods 22 are arranged at equal intervals along the axial direction of the cleaning roller 4. The length of the fixed sleeve 11 in the axial direction of the cleaning roller 4 is less than the length of the cleaning roller 4. When the height of the plate body is different in the vertical placement state of the building formwork, the scraping plates 13 that are not in contact with the building formwork in the axial direction of the cleaning roller 4 remain extended, and the opening degree of the corresponding connecting grooves 12 remains the smallest, further ensuring the effect of centralized suction of dust. Refer to Figure 9 , the lengths of adjacent scraping plates 13 corresponding to a single telescopic mechanism are different in the radial direction, so that the adjacent contraction ranges of the corresponding folds are different at different positions in the axial direction, thereby generating a shearing force between adjacent contraction points, which is beneficial to opening the agglomerated dust. Refer to Figure 9 , the lengths of the supporting rods 14 corresponding to adjacent scraping plates 13 corresponding to a single telescopic mechanism are different in the circumferential direction, so that the order in which the adjacent supporting rods 14 corresponding to different positions in the axial direction of a single fold of the filter element 18 are separated from contact with the building formwork is different. The supporting rods 14 are sequentially separated from contact with the building formwork, and the transmission drives the corresponding folds to shake multiple times, further improving the effect of shaking off dust, ensuring the regeneration ability, and thus ensuring the stability of the suction effect.

[0035] A balance spring 17 is arranged on one side of the sliding sleeve 15. The adjusting spring 24 can drive the sliding rod 22 to move against the elastic force of the balance spring 17, ensuring a smooth sliding process of the sliding sleeve 15. A pressing mechanism 9 is arranged on one side of the housing 1 close to the guiding roller 3. The pressing mechanism 9 is located inside the conveyor belt 2. The pressing mechanism 9 includes a fixed seat 901. A moving plate 902 is slidably clamped on one side of the fixed seat 901. The moving plate 902 can slide horizontally without detaching from the fixed seat 901. A pressing roller 903 is rotatably arranged on one side of the moving plate 902. A pressing spring 904 is fixedly connected to one side of the moving plate 902. One end of the pressing spring 904 is fixedly connected to the fixed seat 901. The pressing spring 904 is used to drive the pressing roller 903 to move, thereby driving the belt surface of the conveyor belt 2 to press the end face of the building formwork for removing waste.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
