Description

Technical Field

[0001] This utility model relates to the technical field of cement board processing equipment, specifically to a lifting-type cement board processing and compaction device. Background Technology

[0002] In the production and processing of cement boards, the compaction process is a crucial step in ensuring the structural strength, density, and service life of the cement boards. Currently, most commercially available cement board compaction devices employ a fixed-height compaction structure. When compacting cement boards of varying thicknesses, the following problems arise:

[0003] First, the adjustment flexibility is poor: the height of the compaction mechanism of the traditional compaction device is fixed, and it is impossible to make convenient and precise height adjustment according to the actual thickness of the cement board. If different thicknesses of boards need to be processed, different specifications of compaction equipment or complex mechanical modifications to the device are required. The operation is cumbersome, time-consuming and labor-intensive, which seriously affects production efficiency.

[0004] Secondly, uneven compaction: Some height-adjustable compaction devices rely on manual adjustment of bolts for height adjustment, which has low precision and can lead to inconsistent spacing between the compaction mechanism and the cement board. This results in uneven compaction strength in different areas of the board, causing problems such as localized loosening and hollowing, which affects the product quality of the cement board. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting-type cement board processing and compaction device to solve the above problems, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The lifting-type cement board processing and compaction device provided by this utility model includes a base and a gantry frame body. The base is placed horizontally, and the gantry frame body is fixedly installed on both sides of the top surface of the base. The top horizontal part of the gantry frame body is placed horizontally along the longitudinal direction and is equipped with lifting adjustment components. A horizontal lifting seat is arranged between the lifting adjustment components on both sides, and the lifting seat is suspended above the top surface of the base, so as to automatically and accurately adjust the position and height of the lifting seat with the help of the lifting adjustment components.

[0008] The lifting platform assembly is equipped with a plate compaction component, which is used to compact the cement board through the plate compaction component.

[0009] The middle part of the lifting seat is also equipped with a lower pre-compression component, which is used to apply a certain initial pre-compression pressure value to the plate compaction component.

[0010] Preferably, a plurality of pads for stable support are fixedly installed around the bottom surface of the base.

[0011] Preferably, each of the lifting and adjusting components includes an electric telescopic rod body and a guide screw. The electric telescopic rod body is vertically fixed to the center of the top surface of the gantry frame body. The telescopic part at the bottom of the electric telescopic rod body passes through the top and bottom surfaces of the gantry frame body in a vertical sliding fit, and the bottom end is fixed to the corresponding side of the top surface of the lifting seat. The top of the gantry frame body has vertically opened guide holes at the front and rear positions of the electric telescopic rod body. The guide screw is coaxially inserted into each guide hole in a vertical sliding fit, and the bottom end of the guide screw is fixed to the corresponding side of the top surface of the lifting seat.

[0012] Preferably, the portion of the guide screw extending out of the top of the guide hole is coaxially engaged with a safety nut, and the periphery of the safety nut is provided with anti-slip texture.

[0013] Preferably, the bottom end of the safety nut is provided with a tapered locking surface, and the top of the guide hole is provided with a tapered mating surface that matches the tapered locking surface. When the safety nut is tightened toward the guide hole, the tapered locking surface can fit tightly with the tapered mating surface.

[0014] Preferably, the plate compaction assembly includes a vibratory motor body and a compaction base plate. The vibratory motor body is placed flat below the bottom surface of the lifting seat, and the flat compaction base plate is installed at the bottom of the vibratory motor body, with the compaction base plate suspended directly above the base plate. Support rods are vertically fixed at the four corners of the top surface of the compaction base plate. The lifting seat has vertically formed mating holes at the four corners above the compaction base plate, and the support rods pass vertically through the mating holes in a coaxial sliding fit. At the same time, an end plate with an outer diameter larger than the diameter of the mating hole is coaxially fixed at the top of each support rod.

[0015] Preferably, the portion of the support rod between the bottom of the end plate and the top of the lifting seat is coaxially fitted with a buffer spring in a clearance fit, and both ends of the buffer spring are respectively fixedly connected to the bottom surface of the end plate and the top surface of the lifting seat.

[0016] Preferably, the lower preload assembly includes a mounting hole and a preload stud. The mounting hole is vertically opened in the middle of the lifting seat. The preload stud is vertically inserted into the mounting hole in a threaded manner, and the bottom end of the preload stud is suspended directly above the highest position of the outer periphery of the vibration motor body.

[0017] Preferably, the top of the preloaded stud is coaxially mounted with a handwheel for easy handling.

[0018] Preferably, the bottom end of the preloaded stud is coaxially mounted with an elastic end of buffer material, and the bottom end of the elastic end is suspended directly above the highest position of the outer periphery of the vibration motor body.

[0019] The aforementioned lifting-type cement slab processing and compaction device, in practical use, features lifting adjustment components on both sides of the base, with a lifting seat combined between these components. The compaction component is then positioned in the center of the lifting seat. By using the electric telescopic rod of the lifting adjustment components to adjust the lifting seat, the height of the compaction component can be automatically and precisely adjusted. This adapts to the compaction needs of cement slabs of different thicknesses. The lifting adjustment operation is convenient and highly accurate, effectively improving the overall versatility and production efficiency of the device. Furthermore, the guide screw of the lifting adjustment components... The vertical sliding of the guide hole provides stable guidance and correction during the lifting and adjusting process of the lifting seat and the compacting assembly, preventing horizontal deviation during adjustment and use. Furthermore, since the guide screw of the lifting adjustment assembly also has a safety height limit function, upon completion of adjustment, the conical locking surface at the bottom of the safety nut and the conical mating surface at the top of the guide hole tightly engage, generating a radial clamping force. This method safely limits the descent of the lifting seat and the compacting assembly to the designated height. This method also facilitates the repeated lowering and adjustment of the lifting platform and the plate compaction assembly to a designated height, improving the stability and reliability of the lifting adjustment assembly for repeated use. Furthermore, after the lifting platform and the plate compaction assembly lower to adjust the compaction base plate to a suitable initial distance from the upper surface of the cement slab, the vibration motor of the plate compaction assembly drives the compaction base plate to vibrate the surface of the cement slab, thus achieving the compaction operation of the cement slab. The compaction process is reliable and easy to implement. Simultaneously, the vertical sliding of the support rod along the mating hole and the reciprocating extension and retraction of the buffer spring allow for monitoring of the compaction process of the compaction base plate on the surface of the cement slab. The vertical guiding and buffering protection further prevents horizontal deviation of the plate compaction component during use, and also provides buffering protection for the compaction base plate during use. Since the lower pre-compression component is also assembled in the middle of the lifting seat, the initial pre-compression pressure value of the bottom end of the pre-compression stud on the vibratory motor body can be adjusted by turning the pre-compression stud of the lower pre-compression component. This allows for adjustment of the initial compression degree of the buffer spring, which facilitates the stable excitation of the compaction base plate by applying a certain pre-compression to the vibratory motor body from the top, and also makes it easy to adjust the buffer spring to a suitable operating state.

[0020] The beneficial effects are as follows: 1. The present invention is provided with lifting and adjusting components on both sides of the base, and a lifting seat is combined between the lifting and adjusting components on both sides. A plate compaction component is combined in the middle of the lifting seat. Then, by means of the electric telescopic rod body of the lifting and adjusting component driving the lifting seat to lift and adjust, the position height of the plate compaction component can be automatically and accurately adjusted. It can adapt to the compaction needs of cement boards of different thicknesses and specifications. The lifting and adjusting operation is convenient and highly accurate, effectively improving the versatility and production efficiency of the device in the overall use process.

[0021] 2. By sliding the guide screw of the lifting adjustment component vertically along the guide hole, the lifting adjustment process of the lifting seat and the plate compaction component can be stably guided and corrected, which can not only prevent the lifting seat and the plate compaction component from being horizontally tilted during the adjustment process, but also prevent the lifting seat and the plate compaction component from being horizontally tilted during use.

[0022] 3. The guide screw of the lifting adjustment component is also equipped with a safety height limit function. When the adjustment is completed, the tapered locking surface at the bottom of the safety nut and the tapered mating surface at the top of the guide hole are closely fitted to form a radial clamping force. This method can not only safely limit the descent of the lifting seat and the plate compaction component to the specified height, but also facilitate the repeated descent and adjustment of the lifting seat and the plate compaction component to the specified height, which helps to improve the stability and reliability of the lifting adjustment component for repeated use.

[0023] 4. After the lifting seat and the slab compaction assembly descend to adjust the compaction base plate to a suitable initial distance from the upper surface of the cement board, the compaction operation of the cement board can be achieved by the vibration motor body of the slab compaction assembly driving the compaction base plate to vibrate the surface of the cement board. The compaction process of the cement board is reliable and easy to implement. At the same time, by the vertical sliding of the support rod along the mating hole and the reciprocating extension and retraction of the buffer spring, the process of the compaction base plate compacting the surface of the cement board can be guided, corrected and buffered in the vertical direction, further avoiding the horizontal deviation of the slab compaction assembly during use, and also providing buffer protection for the use of the compaction base plate.

[0024] 5. The middle part of the lifting seat is also equipped with a lower pre-compression component. By turning the pre-compression stud of the lower pre-compression component, the initial pre-compression pressure value of the bottom end of the pre-compression stud on the vibratory motor body can be adjusted, thereby adjusting the initial compression degree of the buffer spring. This makes it easy to apply a certain pre-compression to the vibratory motor body from the top to stably excite and compact the base plate, and also makes it easy to adjust the buffer spring to a suitable operating state.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] See Figures 1-7 As shown, this utility model provides a lifting-type cement board processing and compaction device, including a base 3 and a gantry frame body 1. The base 3 is horizontally arranged, and the gantry frame body 1 is fixedly installed on both sides of the top surface of the base 3. The top horizontal part of the gantry frame body 1 is horizontally arranged along the longitudinal direction and is equipped with lifting adjustment components 4. A horizontally arranged lifting seat 2 is arranged between the lifting adjustment components 4 on both sides, and the lifting seat 2 is suspended above the top surface of the base 3, so as to automatically and precisely adjust the position and height of the lifting seat 2 with the help of the lifting adjustment components 4. Specifically, the lifting adjustment components 4 all include an electric telescopic rod body 403 and a guide screw 401. The electric telescopic rod body 403 is vertically fixed in the middle of the top surface of the gantry frame body 1. The telescopic part 404 at the bottom of the electric telescopic rod body 403 passes through the top and bottom surfaces of the gantry frame body 1 in a vertical sliding fit. The bottom ends are all fixed to the corresponding side of the top surface of the lifting seat 2. The top of the gantry frame body 1 has guide holes 405 vertically opened at the front and rear positions of the electric telescopic rod body 403. The guide holes 405 are all coaxially inserted with guide screws 401 in a vertical sliding fit. The bottom ends of the guide screws 401 are all fixed to the corresponding side of the top surface of the lifting seat 2. The purpose of this setting is that, firstly, by using the electric telescopic rod body 403 of the lifting adjustment component 4 to drive the lifting seat 2 to lift and adjust, the position and height of the plate compaction component 5 can be automatically and accurately adjusted, which can adapt to the compaction needs of cement boards of different thicknesses and specifications. The lifting and adjustment operation is convenient and highly accurate. At the same time, by the guide screws 401 of the lifting adjustment component 4 sliding vertically along the guide holes 405, the lifting seat 2 and the plate compaction component 5 can be stably guided and corrected during the lifting and adjustment process.

[0037] See Figures 1-5As shown, the lifting platform 2 is equipped with a slab compaction component 5, which is used to compact the cement slab. Specifically, the slab compaction component 5 includes a vibratory motor body 506 and a compaction base plate 505. The vibratory motor body 506 is placed flat below the bottom surface of the lifting platform 2, and the flat compaction base plate 505 is installed at the bottom of the vibratory motor body 506, with the compaction base plate 505 suspended directly above the base plate. Support rods 504 are vertically fixed at the four corners of the top surface of the compaction base plate 505. The lifting platform 2 has vertically opened mating holes 503 above the four corners of the compaction base plate 505, and the support rods 504 all pass vertically through the mating holes 503 in a coaxial sliding fit. At the same time, the top of each support rod 504 is coaxially fixed with an end plate 501 with an outer diameter larger than the diameter of the mating hole 503. The portion between the bottom of the end plate 501 and the top of the lifting seat 2 is coaxially fitted with a buffer spring 502 in a clearance fit. Both ends of the buffer spring 502 are fixedly connected to the bottom surface of the corresponding end plate 501 and the top surface of the lifting seat 2, respectively. The purpose of this arrangement is that after the lifting seat 2 and the plate compaction component 5 descend to adjust the compaction base plate 505 to a suitable initial distance from the upper surface of the cement board, the compaction operation of the cement board can be achieved by driving the compaction base plate 505 to vibrate the surface of the cement board through the vibration motor body 506 of the plate compaction component 5. The compaction process of the cement board is reliable and easy to implement. At the same time, by the vertical sliding of the support rod 504 along the mating hole 503 and the reciprocating extension and retraction of the buffer spring 502, the process of the compaction base plate 505 compacting the surface of the cement board can be guided, corrected and buffered in the vertical direction.

[0038] See Figures 1-7 As shown, a lower pre-compression component 6 is also assembled in the middle of the lifting base 2. This component is used to apply a certain initial pre-compression pressure value to the plate compaction component 5. Specifically, the lower pre-compression component 6 includes a mounting hole 603 and a pre-compression stud 602. The mounting hole 603 is vertically opened in the middle of the lifting base 2. The pre-compression stud 602 is vertically inserted into the mounting hole 603 by means of thread engagement. The bottom end of the pre-compression stud 602 is suspended directly above the highest position of the outer periphery of the vibratory motor body 506. The reason for this arrangement is that by turning the pre-compression stud 602 of the lower pre-compression component 6, the initial pre-compression pressure value of the bottom end of the pre-compression stud 602 on the vibratory motor body 506 can be adjusted, thereby adjusting the initial compression degree of the buffer spring 502.

[0039] See Figures 1-7As shown, the following optimizations have been made to this application. Specifically, multiple feet 301 for stable support are fixedly installed around the bottom surface of the base 3, so that the base 3 can be stably and horizontally supported by the feet 301. Optionally, the portion of the guide screw 401 extending out of the guide hole 405 is coaxially engaged with a safety nut 402, and the outer periphery of the safety nut 402 is provided with anti-slip texture, so that the safety nut 402 can be directly tightened and loosened by hand. Furthermore, the bottom end of the safety nut 402 is provided with a conical locking surface 406, and the top of the guide hole 405 is provided with a surface that matches the conical locking surface 406. The tapered mating surface 407 is fitted, and when the safety nut 402 is tightened toward the guide hole 405, the tapered locking surface 406 can fit tightly with the tapered mating surface 407. With this setting, when the adjustment is completed, the tapered locking surface 406 at the bottom of the safety nut 402 fits tightly with the tapered mating surface 407 at the top of the guide hole 405, which can form a radial clamping force. This can both safely limit the descent of the lifting seat 2 and the plate compaction component 5 to the specified height, and also facilitate the repeated descent and adjustment of the lifting seat 2 and the plate compaction component 5 to the specified height.

[0040] See Figures 1-7 As shown, a handwheel 601 is coaxially mounted on the top of the preload stud 602 for easy gripping, so that the preload stud 602 can be rotated by applying force through the handwheel 601. Optionally, a cushioning elastic end 604 is coaxially mounted on the bottom of the preload stud 602, and the bottom of the elastic end 604 is suspended directly above the highest position of the outer periphery of the vibratory motor body 506. With this arrangement, the elastic end 604 can be pressed and tightened on the top of the vibratory motor body 506, which can both cushion and protect the vibratory motor body 506 during use, and also play a certain role in preventing the preload stud 602 from loosening.

[0041] With the above structure, in practical use, since lifting adjustment components 4 are provided on both sides of the base 3, and a lifting seat 2 is combined between the lifting adjustment components 4 on both sides, and a plate compaction component 5 is combined in the middle of the lifting seat 2, the position and height of the plate compaction component 5 can be automatically and precisely adjusted by the electric telescopic rod body 403 of the lifting adjustment component 4 to drive the lifting seat 2. This can adapt to the compaction needs of cement boards of different thicknesses and specifications. The lifting adjustment operation is convenient and highly accurate, effectively improving the versatility and production efficiency of the device in the overall use process. Furthermore, because the guide screw 401 of the lifting adjustment component 4 slides vertically along the guide hole 405, it can... The lifting adjustment process of the lifting seat 2 and the plate compaction component 5 is stably guided and corrected to prevent horizontal deviation during adjustment and use. Furthermore, since the guide screw 401 of the lifting adjustment component 4 is equipped with a safety height limit function, when the adjustment is complete, the conical locking surface 406 at the bottom of the safety nut 402 and the conical mating surface 407 at the top of the guide hole 405 tightly engage to form a radial clamping force. This method safely limits the descent of the lifting seat 2 and the plate compaction component 5 to the designated height, while also facilitating the lifting... The lowering seat 2 and the plate compaction component 5 can be repeatedly lowered and adjusted to a specified height, which helps to improve the stability and reliability of the lifting adjustment component 4 for repeated use. Furthermore, after the lowering seat 2 and the plate compaction component 5 have lowered to adjust the compaction base plate 505 to a suitable initial distance from the upper surface of the cement board, the compaction operation of the cement board can be achieved by the vibration motor body 506 of the plate compaction component 5 driving the compaction base plate 505 to vibrate the surface of the cement board. The compaction process of the cement board is reliable and easy to implement. Simultaneously, the vertical sliding of the support rod 504 along the mating hole 503 and the reciprocating extension and retraction of the buffer spring 502 can provide vertical guidance and correction during the compaction process of the compaction base plate 505 on the surface of the cement board. In addition to buffering and protection, it further avoids horizontal deviation of the plate compaction component 5 during use, and also provides buffering protection for the compaction base plate 505 during use. Since the middle part of the lifting seat 2 is also equipped with the lower top pre-pressure component 6, the initial pre-pressure pressure value of the bottom end of the pre-pressure component 602 on the vibratory motor body 506 can be adjusted by turning the pre-pressure stud 602 of the lower top pre-pressure component 6. This allows for adjustment of the initial compression degree of the buffer spring 502, which facilitates the application of a certain pre-pressure from the top to the vibratory motor body 506 to stably excite and compact the base plate 505, and also facilitates the adjustment of the buffer spring 502 to a suitable operating state.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
