Description

Technical Field

[0001] This utility model belongs to the field of gypsum building material processing technology, and in particular relates to a clamping and fixing device for processing building gypsum. Background Technology

[0002] In the processing of architectural gypsum products, traditional clamping and fixing devices generally adopt mechanical clamping structures or bolt-adjustable fixing plates. Fixing is achieved by manually tightening the bolts to push the moving plate against the edge of the gypsum board. This design mainly facilitates the processing of gypsum boards; however, existing technologies also have some significant drawbacks: 1. Low efficiency: Each time a workpiece is changed, the bolt position needs to be repeatedly adjusted, and a single clamping takes 5-15 minutes, which seriously slows down the production line rhythm. 2. High damage rate: Stress concentration at rigid clamping points, especially for thin gypsum boards, can lead to excessive local pressure and edge cracking. Therefore, there is an urgent need for a new type of fixing device that is self-adaptive, quick-clamping, damage-resistant, and dust-suppressing. Utility Model Content

[0003] The purpose of this utility model is to provide a clamping and fixing device for processing architectural plaster, so as to solve the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention provides a clamping and fixing device for processing architectural plaster, comprising a steel frame. A sliding mechanism is provided on the steel frame, the sliding mechanism comprising a top plate, a central shaft, a gear disk, a sliding sleeve, a sliding toothed plate, and a rack. The top plate is located at the center of the upper part of the steel frame, the central shaft is located below the top plate, the gear disk is rotatably mounted on the central shaft, the sliding sleeve is centrally symmetrically arranged below the top plate around the gear disk, two sliding toothed plates are provided, and the sliding toothed plates are slidably connected through the sliding sleeves respectively. A rack is provided at one end of the sliding toothed plate, and the rack meshes with the gear disk and rotates. A movable frame is provided below the end of the sliding toothed plate away from the rack, and two electric cylinders with relative telescopic movement are respectively provided between the two movable frames. Multiple sets of cross frames are provided inside the movable frames, and multiple electric suction cups are provided on the cross frames through fastening plates.

[0005] Preferably, a slide rail is provided below the steel frame, and a slider is provided above the moving frame, with the slider and the slide rail being adapted to achieve a sliding connection.

[0006] Preferably, the movable frame is provided with an equipment compartment on the side away from the crossbeam, and the equipment compartment is equipped with an atomizing mechanism to reduce dust emission.

[0007] Preferably, the atomizing mechanism includes a water tank, a water pump, a water collecting plate, a rubber ring, and atomizing holes. The water tank is located inside the equipment compartment, the water pump is located inside the equipment compartment and is connected to the water tank via a water pipe, the water collecting plate is mounted on both sides of the movable frame via fixed columns and is connected to the water pump via a water pipe, the rubber ring is installed through the side of the movable frame and allows the water pipe to extend out, the design of the rubber ring further enhances the stability of water delivery, and multiple atomizing holes are opened on the water collecting plate.

[0008] Preferably, turbine fans are arranged opposite each other on both sides of the movable frame.

[0009] Preferably, the inner side of the movable frame is provided with a dust-adhesive plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention solves the efficiency and damage problems of traditional fixing devices through automated synchronous clamping and surface contact adsorption. The meshing transmission of the gear disk and double sliding rack ensures the absolute synchronous displacement of the moving frames on both sides. Combined with the automatic extension and retraction drive of the electric cylinder, it completely replaces manual bolt adjustment. The negative pressure adsorption mechanism of the electric suction cup array enables easy fixing and release of gypsum board. The distributed electric suction cups on the cross frame form a flexible support surface, which evenly disperses the load through vacuum adsorption, eliminating local stress concentration of mechanical clamps. Especially for thin gypsum board, the surface contact mode effectively avoids the risk of edge and corner cracking. The precise proportional movement of the electric cylinder in conjunction with the gear disk and rack transmission allows the spacing of the moving frames to adapt to different specifications of boards, significantly improving the versatility of the equipment. In addition, the integrated dust suppression design synchronously controls processing dust, forming a multi-dimensional improvement in efficiency, protection and environmental protection, which meets the needs of intelligent processing of modern gypsum products.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1, such as Figure 1-6 As shown, the specific design of the aforementioned key components will be described in detail below: A clamping and fixing device for processing architectural plaster includes a steel frame 1. A sliding mechanism 2 is provided on the steel frame 1. The sliding mechanism 2 includes a top plate 201, a central shaft 202, a gear disk 203, a sliding sleeve 206, sliding toothed plates 204, and a rack 205. The top plate 201 is located at the center of the top of the steel frame 1. The central shaft 202 is located below the top plate 201. The gear disk 203 is rotatably mounted on the central shaft 202. The sliding sleeve 206 is centrally symmetrically arranged below the top plate 201 around the gear disk 203. Two sliding toothed plates 204 are provided. 4. The sliding sleeves 206 are slidably connected. A rack 205 is provided at one end of the sliding toothed plate 204. The rack 205 meshes with the gear disk 203 and rotates. A movable frame 3 is provided below the end of the sliding toothed plate 204 away from the rack 205. Two electric cylinders 5 with relative telescopic movement are provided between the two movable frames 3. Multiple sets of cross frames 6 are provided inside the movable frame 3. Multiple electric suction cups 8 are provided on the cross frames 6 through fastening plates 7. A slide rail 11 is provided below the steel frame 1. A slider 4 is provided above the movable frame 3. The slider 4 is adapted to the slide rail 11 to achieve a sliding connection.

[0017] When the electric cylinder 5 pushes the moving frame 3, it causes the sliding toothed plate 204 to move horizontally along the sliding sleeve 206. The meshing of the rack 205 and the gear disk 203 causes the sliding toothed plates 204 on both sides to move in opposite directions at equal distances, ensuring that the two moving frames 3 are always symmetrically displaced about the central axis 202. The electric suction cups 8 are arranged in a matrix on the horizontal frame 6 inside the moving frame 3. When the gypsum board is placed between the two moving frames 3, the electric suction cups 8 contact the surface of the board and start negative pressure adsorption to form a uniformly distributed surface contact fixation, replacing the traditional point mechanical extrusion. The electric cylinder 5 drives the synchronous mechanism of gear disk 203 and rack 205 to realize the automatic and precise adjustment of the spacing of the moving frames 3. There is no need for repeated manual adjustment, and the clamping efficiency is significantly improved. The electric suction cups 8 disperse the load through vacuum adsorption, avoiding the cracking of the gypsum board edges and corners caused by local stress concentration. It is especially suitable for the processing of brittle thin plates. The slide rail 11 and slider 4 constrain the moving frame 3 to move only along the horizontal axis, eliminating off-center load vibration and ensuring the accuracy of movement. The synergistic design of synchronous transmission and adsorption fixation not only meets the needs of rapid material change, but also provides a stable execution basis for subsequent dust suppression, realizing the integration of multiple functions.

[0018] A device compartment 12 is provided on the side of the movable frame 3 away from the crossbar 6. The device compartment 12 is equipped with an atomizing mechanism 9 to reduce dust flying. The atomizing mechanism 9 includes a water tank 901, a water pump 902, a water collecting plate 903, a rubber ring 904, and atomizing holes 905. The water tank 901 is located inside the device compartment 12. The water pump 902 is located inside the device compartment 12 and is connected to the water tank 901 through a water pipe. The water collecting plate 903 is located on both sides of the movable frame 3 through a fixing column 13 and is connected to the water pump 902 through a water pipe. The rubber ring 904 is provided through the side of the movable frame 3 and allows the water pipe to extend out. The design of the rubber ring 904 further enhances the stability of water pipe transportation. Multiple atomizing holes 905 are opened on the water collecting plate 903. Turbine fans 10 are arranged opposite each other on both sides of the movable frame 3. A dust-adhesive plate 14 is provided on the inner side of the movable frame 3.

[0019] The water pump 902 delivers water from the water tank 901 to the water collection plates 903 on both sides of the moving frame 3. The water flows through the atomizing holes 905 to form a micron-level water mist curtain, which is evenly sprayed onto the gypsum processing area. The wet dust particles increase their weight and settle. The turbine fan 10 generates a directional airflow, pushing the scattered dust towards the inner dust-adhesive plate 14. At the same time, the airflow accelerates the diffusion of the water mist, enhancing the encapsulation effect on suspended dust. The dust-adhesive plate 14 adsorbs and captures residual particles. The water mist curtain directly covers the dust-generating points near the gypsum, suppressing dust diffusion at the source. Compared with post-dust removal equipment, the efficiency is significantly improved. The airflow guidance of the turbine fan 10 and the water mist spraying form a spatial synergy, which not only expands the dust suppression coverage area but also prevents wet dust from adhering to the equipment. The physical adsorption of the dust-adhesive plate 14, combined with the water mist settling, avoids the mud and sludge cleaning problems caused by traditional wet dust removal. The rubber ring 904, including the design around the water pipe, eliminates the risk of transmission leakage caused by water pipe vibration, ensuring the continuous and stable dust suppression function during the reciprocating motion of the moving frame 3.

[0020] The gear and rack 205 synchronous mechanism ensures symmetrical and precise displacement of the double moving frames 3. The electric suction cup 8 matrix forms a uniform adsorption force field, effectively solving the stress concentration damage caused by traditional mechanical clamping, while achieving rapid clamping. The atomizing mechanism 9 forms a water mist barrier around the material during movement. Combined with the airflow guidance of the turbine fan 10 and the physical adsorption of the dust-adhesive plate 14, it suppresses dust diffusion from the source. The guide rail 11 and slider 4 ensure the stable operation of the moving frame 3. The rubber ring 904 sealing design solves the hidden danger of water pipe vibration leakage in moving parts, ensuring long-term synergy between dust suppression function and clamping movement, meeting the needs of modern green intelligent manufacturing of gypsum products.
