[0002] In modern architecture, after the main load-bearing structure is completed, lightweight partition walls are generally used for spatial separation. After the lightweight partition walls are joined, there are usually seams. If a mesh fabric is not attached to these seams during wall painting, cracks will appear on the painted surface, affecting the aesthetics. The mesh fabric is usually initially fixed with cement mortar. The traditional process for fixing the mesh fabric to the outside of the seams is as follows: first, the mesh fabric is laid on the outside of the seam; then, mortar is used to temporarily fix the top, middle, and bottom of the mesh fabric; after applying the mortar, a trowel and plasterboard are used to spread mortar over the entire area where the mesh fabric is distributed, thus achieving effective fixation. This traditional process of fixing the mesh fabric with plaster is inefficient and cumbersome. Utility Model Content

The pressure exerted by the rubber roller on the mesh fabric causes the mesh fabric roll to rotate continuously as the mortar storage box moves upward. This continuous rotation allows the mesh fabric to be continuously laid on the lightweight partition wall panel, thus coordinating with the movement of the squeegee to fix the mesh fabric in place. The rubber roller utilizes a second spring for pressure, ensuring continuous and effective pressure on the mesh fabric. The squeegee's downward movement allows for a single plastering operation, greatly simplifying the process and improving the efficiency of mesh fabric fixation. The mortar storage box's left-high, right-low orientation ensures sufficient mortar flow from the outlet, allowing the squeegee to continue plastering. Attached Figure Description

[0016] The following will describe specific embodiments and appendices. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] In the field of building construction technology, mesh fabric is a commonly used product for preventing cracks in painted walls. It has strong flexibility. The main raw material of mesh fabric is glass fiber yarn, which is produced by weaving glass fiber yarn in a certain way.

[0018] This utility model provides an auxiliary device for fixing mesh cloth plastering in the joints of lightweight partition walls, including a movable support base 1, a movable support frame 2, a lifting mechanism 3, a mortar storage box 4, a mesh cloth support roller 5, and a mesh cloth rolling assembly. The movable support base 1 can move on the ground, which facilitates the movement of this utility model on the ground, thereby enabling large-area mesh cloth plastering and fixing operations. The movable support frame 2 is mounted on the movable support base 1 and can move and be positioned on the movable support frame 2. In practical applications, the movable support frame 2 allows the mortar storage box 4 to be positioned... The movement of the mortar storage box 4 facilitates the adjustment of the distance between it and the lightweight partition wall. The lifting mechanism 3 is mounted on the movable support frame 2. The lifting mechanism 3 can move the mortar storage box 4 up and down and position it. The mortar storage box 4 is distributed with the left side higher than the right side. A mortar outlet 41 is set at the bottom right side of the mortar storage box 4. A scraper 42 with the left side higher than the right side is set to the right of the mortar outlet 41. In actual application, after adjusting the distance between the mortar storage box 4 and the lightweight partition wall, the scraper 42 is in the mortar application position. At this time, after the mixed cement mortar is put into the mortar storage box 4, the cement mortar will be lifted by gravity. The mortar automatically flows into the mortar outlet 41 and further flows between the scraper 42 and the lightweight partition wall. As the mortar storage box 4 slowly moves upward, the cement mortar is applied to the lightweight partition wall. The mortar storage box 4 has a receiving cavity 43, which can hold a certain amount of cement mortar, thus enabling continuous application of cement mortar to the wall for a certain period of time. A mortar inlet is provided on the left side of the mortar storage box 4. The mixed cement mortar is placed into the receiving cavity 43 through the mortar inlet. In practical applications, to ensure that the cement mortar in the receiving cavity 43 continuously flows onto the scraper 42, a [missing information - likely a device or mechanism] can be provided inside the receiving cavity 43. After the mixed cement mortar is placed into the receiving cavity 43, the grouting block is then placed into the receiving cavity 43. Under the action of gravity, the grouting block slides towards the mortar outlet 41. During its sliding process, it pushes the cement mortar to move continuously towards the mortar outlet 41, thereby realizing the supply of cement mortar to the scraper 42. In order to prevent cement mortar from flowing out of the mortar outlet 41 and causing cement mortar waste when the cement mortar application operation is not performed, a gate 411 is set on the upper outer side of the mortar outlet 41. When the gate 411 moves up a certain distance, the mortar outlet 41 is opened. When the gate 411 is pressed down to the bottom, the mortar outlet 41 is closed.Two fixed-distance wheels 44 are installed at the middle right side of the mortar storage box 4. Specifically, the fixed-distance wheels 44 are rotatably mounted on two front-to-back support rods distributed opposite each other on the right side wall of the mortar storage box 4. During the actual plastering process, the right side of the fixed-distance wheels 44 is in contact with the lightweight partition wall panel. Since the positions of the fixed-distance wheels 44 and the scraper 42 are relatively fixed, when the right side wall of the fixed-distance wheels 44 is in contact with the lightweight partition wall panel, the scraper 42 will not move horizontally relative to the lightweight partition wall panel when the fixed-distance wheels 44 do not move away from the lightweight partition wall panel. Thus, as the mortar storage box 4 continues to move upward, the scraper 42 is used to apply mortar to the joints of the lightweight partition wall panel. When using the scraper 42 to apply cement mortar, in order to effectively prevent cement mortar from overflowing from the front and back sides of the scraper 42 and causing waste, the upper front and back sides of the scraper 42 are... A baffle plate 421 is provided on each side; the horizontal distance difference between the rightmost side of the scraper plate 42 and the rightmost side of the fixed-distance wheel 44 to the same right vertical wall is L, 2mm≤L≤4mm, where L is the thickness of cement mortar applied by the scraper plate 42 to the lightweight partition wall. In this specific embodiment, L can be 3mm; the mesh support roller 5 is rotatably disposed on the upper right side of the mortar storage box 4, and the mesh support roller 5 is used to realize the rotational support of the mesh roll. The finished mesh is generally packaged and transported in roll form. When the mesh roll is installed on the mesh support roller 5, the rotation of the mesh support roller 5 can realize the rotation of the mesh roll, thereby facilitating the orderly release of the mesh; the mesh rolling assembly is disposed in the middle right area of ​​the mortar storage box 4, and the mesh rolling assembly is used to roll the mesh.

[0019] Based on the above embodiments, the specific implementation of the movable support base 1 is as follows: the movable support base 1 includes a support base plate 11, and four universal wheels 12 with braking function are arranged around the bottom of the support base plate 11. The rolling support of the four universal wheels 12 with braking function facilitates the flexible movement of the support base plate 11. At the same time, the braking function of the universal wheels 12 with braking function facilitates the keeping of the support base plate 11 stationary on the ground.

[0020] When using this utility model to fix the mesh cloth for plastering, in order to improve the stability of the movable support base 1 on the ground, four adjustable legs 14 are provided on the support base plate 11. Each adjustable leg 14 includes a support pad 142 and an adjusting threaded rod 141. The support pad 142 is fixedly installed on the bottom of the adjusting threaded rod 141. The adjusting threaded rod 141 is sleeved on the support base plate 11. The support pad 142 can be moved up and down by rotating the adjusting threaded rod 141. In practical applications, when it is necessary to move the support base plate 11, the adjusting threaded rod 141 is rotated to separate the support pad 142 from the ground. When the support pad 142 is needed to support the support base plate 11 on the ground, the adjusting threaded rod 141 is rotated to make the support pad 142 contact the ground. At the same time, the rotation of the adjusting threaded rod 141 stops when the universal wheel 12 with braking function is disengaged from the ground. The horizontality of the support base plate 11 can also be adjusted by the four adjusting threaded rods 141, thereby realizing the verticality adjustment of the moving support frame 2, so that the lower right side of the scraper plate 42 is parallel to the lightweight partition wall.

[0021] Based on the above embodiments, the specific implementation of the movable support frame 2 is as follows: the movable support frame 2 has a square structure, and two inverted T-shaped grooves 13 are provided on the upper part of the support base plate 11. Two inverted T-shaped sliders 211 provided at the bottom of the movable support frame 2 are slidably sleeved in the corresponding inverted T-shaped grooves 13. A first guide rod 131 is provided in the inverted T-shaped grooves 13, and the first guide rod 131 is slidably sleeved on the corresponding inverted T-shaped slider 211. The inverted T-shaped slider 211 can slide freely relative to the inverted T-shaped grooves 13 and the first guide rod 131. The two inverted T-shaped sliders 211 support the entire movable support frame 2. When the inverted T-shaped sliders 211 move, the entire movable support frame 2 moves. A first spring 132 is sleeved on the outside of the first guide rod 131, and the first spring 132 is located on the left side of the corresponding inverted T-shaped slider 211. In practical applications, when the fixed-distance wheel 44 comes into contact with the lightweight partition board and the first spring 132 is in a compressed state, the first spring 132 always applies a rightward thrust to the fixed-distance wheel 44. Thus, under the condition that the movable support 1 remains stationary, it can be ensured that the fixed-distance wheel 44 is always in contact with the lightweight partition board, thereby effectively ensuring the thickness of the cement mortar coating, so that the scraper 42 can evenly apply the cement mortar to the joints of the lightweight partition board.

[0022] Based on the above embodiments, the specific implementation of the lifting mechanism 3 is as follows: The lifting mechanism 3 includes a movable support plate 31, a rack 32, a drive gear 33, and a brake motor 34. After the brake motor 34 stops working, its output shaft can stop in time. The brake motor 34 is a known mature technology product in the existing technical field, so the specific structure and function of the brake motor 34 will not be described in detail here. The front and rear ends of the movable support plate 31 are slidably sleeved on the two vertical round rods 22 of the movable support frame 2. The rack 32 is vertically fixed between the upper horizontal plate 23 and the lower horizontal plate 21 of the movable support frame 2 and the rack 32 passes through... A through-hole is provided on the movable support plate 31, which allows the rack 32 to not obstruct the movable support plate 31. The brake motor 34 is fixedly mounted on the movable support plate 31. The drive gear 33 is mounted on the output shaft of the brake motor 34 and meshes with the rack 32. When the brake motor 34 drives the drive gear 33 to rotate, the meshing relationship between the drive gear 33 and the rack 32 enables the movable support plate 31 to move up and down. The mortar storage box 4 is fixedly mounted on the movable support plate 31, and the movement of the movable support plate 31 drives the mortar storage box 4 to move up and down.

[0023] Based on the above embodiments, the specific implementation of the mesh fabric rolling assembly is as follows: The mesh fabric rolling assembly includes a first U-shaped frame 61, a second U-shaped frame 62, and a rubber roller 63. The first U-shaped frame 61 is fixedly installed on the right side wall of the mortar storage box 4. Two second guide rods 621 are provided on the left side of the second U-shaped frame 62. The two second guide rods 621 are slidably sleeved on the first U-shaped frame 61, and a limiting plate is provided on the left side of the second guide rods 621. By using the blocking effect of the limiting plate, the second guide rods 621 can be prevented from detaching from the first U-shaped frame 61. A second spring 64 is sleeved on the second guide rod 621, and the second spring 64 is clamped between the first U-shaped frame 61 and the second U-shaped frame 62. The rubber roller 63 is rotatably mounted on the second U-shaped frame 62, and the second spring 64 always applies a pushing force to the second U-shaped frame 62. In actual application, in order to ensure that the rubber roller 63 can roll the mesh cloth, the fixed wheel 44 needs to contact the lightweight partition board later than the rubber roller 63. When the fixed wheel 44 presses against the lightweight partition board, the second spring 64 is compressed to a certain extent, so that the second spring 64 can always apply a pushing force to the rubber roller 63. Under the compression of the second spring 64, the rubber roller 63 can always maintain effective rolling of the mesh cloth. Then, as the mortar storage box 4 drives the mesh cloth roll and the rubber wheel 63 to move upward, the mesh cloth roll can rotate to achieve orderly release of the mesh cloth.

[0024] Based on the above embodiments, the specific implementation of the mesh fabric support roller 5 on the upper part of the mortar storage box 4 is as follows: two support rods 51 are provided on the upper right side of the mortar storage box 4, and a U-shaped groove 511 is provided on the upper part of the support rods 51. The two ends of the mesh fabric support roller 5 are rotatably fitted into the corresponding U-shaped grooves 511. To prevent the mesh fabric support roller 5 from moving back and forth in the two U-shaped grooves 511, two limiting plates can be provided at both ends of the mesh fabric support roller 5. The two limiting plates are located between the two support rods 51. When installing the mesh fabric roll, the mesh fabric support roller 5 is first removed and then inserted into the roll of the mesh fabric roll. Then, the mesh support roller 5 is placed back into the two U-shaped grooves 511, and the installation of the mesh roll is completed. When fixing the mesh with plaster, the free end of the mesh roll is pulled out first, and the free end of the mesh roll is moved down to the bottom of the scraper plate 42. After the fixed distance wheel 44 is moved to contact the lightweight partition board, the rubber roller 63 presses the mesh. When the gate plate 411 is moved up and opened, the cement mortar flowing on the scraper plate 42 contacts the lightweight partition board and also squeezes the mesh. Therefore, during the scraping process of the mortar storage box 4, the mesh will not move relative to the lightweight partition board, thus successfully laying the mesh.

[0025] The plastering and fixing process of the mesh fabric using this utility model is as follows: First, install the mesh fabric roll on the mesh fabric support roller 5, and pull down the free end of the mesh fabric roll to move it below the scraper plate 42; Second, move this utility model to the front side of the joint of the lightweight partition wall panel, and make the mortar storage box 4 the lowest position that can achieve plastering on the outside of the joint; Third, put the mixed cement mortar into the receiving cavity 43; Fourth, move this utility model so that both fixed distance wheels 44 are in contact with the surface of the lightweight partition wall panel, and then rotate the adjusting threaded rod 141 to realize the support of the support base plate 11 by the support pad 142. When using the adjusting threaded rod 141 for support, the level of the support base plate 11 can be adjusted with the help of a level so that the moving support frame 2 and the lightweight partition wall panel are aligned. Maintain a vertical and parallel distribution; in the fifth step, pull the gate plate 411 upward to move it a certain distance so that the cement mortar flows from the mortar outlet 41 onto the scraper plate 42. When the cement mortar is in full contact with the lightweight partition wall, the brake motor 34 is activated. After the brake motor 34 is activated, the mortar storage box 4 moves upward at a uniform speed through the cooperation of the drive gear 33 and the rack 32. The upward movement of the mortar storage box 4 drives the scraper plate 42 to move upward. The continuous upward movement of the scraper plate 42 achieves the uniform scraping of cement mortar on the lightweight partition wall. During the scraping of cement mortar, the plastering and fixing of the mesh cloth is achieved simultaneously. When the mortar storage box 4 moves upward to the limit position, the brake motor 34 stops working. Then, use a utility knife to cut the mesh cloth above the scraper plate 42 to complete one plastering and fixing operation of the mesh cloth.
