Description

Technical Field

[0001] This utility model relates to the field of simulated fence production and manufacturing, and in particular to a spraying device for producing simulated fences. Background Technology

[0002] Simulated fences are decorative components that use non-natural materials to simulate the appearance and function of real fences. They are made of materials such as plastic, metal, resin, and bamboo fiber composites and molded to realistically reproduce the styles of traditional fences such as bamboo fences, wooden fences, and stone fences. Functionally, they can separate spaces, beautify the environment, block views, and provide security. They also overcome the shortcomings of natural fences, such as being susceptible to wind and rain erosion, insect infestation, rot, and frequent maintenance. They have advantages such as long service life, resistance to deformation and fading, easy installation, and recyclability. They are widely used in landscape design, courtyard decoration, commercial space partitions, road boundary demarcation, and other scenarios.

[0003] Currently, there are two main methods for spraying simulated fences. One is manual hand-held spraying, where operators need to hold a spray gun and rely on experience and skills to spray each side of the fence. This method is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale production, but also the spraying quality is greatly affected by human factors, which can easily lead to problems such as uneven spraying and inconsistent thickness, resulting in a decrease in the product qualification rate.

[0004] Secondly, some companies use spraying equipment for spraying, but most of the existing equipment sprays only one side, requiring the fence to be flipped over before spraying the other side. This spraying method greatly extends the production cycle, increases the turnaround time and labor costs in the production process. At the same time, during the spraying process, paint mist, dust and other sprayed materials are easily dispersed into the outside world, which not only pollutes the surrounding production environment and increases the cost of workshop cleaning and maintenance, but also damages the respiratory system and skin of workers, seriously threatening the health of employees.

[0005] Therefore, it is necessary to provide a new spraying device for producing simulated fences to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a spraying device for producing simulated fences.

[0007] The present invention provides a spraying device for producing simulated fences, comprising: a spraying machine body, flat spray nozzles, a drive assembly, sliding doors, and top rods. A chain conveyor belt is located at the bottom of the spraying machine body, with its top extending through the bottom of the machine body. Vertically positioned flat spray nozzles are symmetrically arranged inside the machine body, located diagonally within the machine body. A drive assembly is installed between the flat spray nozzles and the machine body, driving the flat spray nozzles to move towards each other for double-sided spraying of the simulated fence. Sliding doors are symmetrically installed at both ends of the machine body to prevent the sprayed material from spreading outwards. Top rods are equidistantly arranged on the outer wall of the chain conveyor belt to drive the sliding doors to move in opposite directions.

[0008] Preferably, the drive assembly includes a motor, gears, and racks. The motor is fixedly installed on the top of the spraying machine body. The output end of the motor extends into the interior of the spraying machine body and is fixedly connected to a gear. Both sides of the gear are meshed with racks. A protective cover is fixedly connected to the top of the interior of the spraying machine body. The racks are slidably connected to the inner wall of the protective cover. A connecting rod is fixedly connected to the middle of the opposite side of the racks. The bottom of the connecting rod is fixedly connected to the corresponding flat spray nozzle.

[0009] Preferably, the inside of the spraying machine body is symmetrically fixedly connected with slide rails parallel to the rack, and the bottom end of each connecting rod is slidably connected to the inner wall of the corresponding slide rail.

[0010] Preferably, the outer wall of the chain conveyor belt is fixedly connected with support rods at equal intervals. Every two adjacent support rods form a group for fixing the fence to be sprayed. The outer wall of one of the two adjacent support rods at the feeding end away from the chain conveyor belt is fixedly connected to the corresponding top rod.

[0011] Preferably, both ends of the spraying machine body are provided with mounting grooves, and springs are fixedly connected to the inner walls of the mounting grooves. A crossbar corresponding to the mounting groove is fixedly connected to the opposite side of the sliding door. The diameter of the crossbar is smaller than the diameter of the corresponding mounting groove. A trapezoidal block corresponding to the top rod is fixedly connected to the bottom of the side of the sliding door near the feeding end.

[0012] Preferably, friction blocks are provided at equal intervals on the outer wall of the crossbar, and the friction between the crossbar and the corresponding mounting groove is less than the elastic force of the spring.

[0013] Preferably, the ends of the top rods are rotatably connected to rotating cylinders, and the bottoms of the sliding doors are symmetrically rotatably connected to rollers.

[0014] Compared with related technologies, the spraying device for producing simulated fences provided by this utility model has the following advantages:

[0015] Beneficial effects:

[0016] The transmission structure of gears and racks driven by motors causes the diagonally distributed flat spray nozzles to move towards each other, enabling simultaneous spraying of both sides of the simulated fence. Compared with the method of spraying one side and then flipping it over, the flipping step is directly eliminated, reducing the turnover time of the fence in the production process and greatly improving the spraying efficiency.

[0017] By installing sliding doors at both ends of the spraying machine body, when the fence moves with the chain conveyor belt, the top rod squeezes the trapezoidal block to open the sliding door. After the fence enters, the sliding door automatically closes, forming a closed spraying space, preventing the sprayed material from overflowing, effectively reducing the diffusion of the sprayed material to the outside world, reducing the concentration of harmful gases and dust in the workshop, improving the working environment, and protecting the health of the workers.

[0018] The protective cover design effectively blocks atomized particles generated during the spraying process, preventing them from entering the transmission components and reducing wear. In the sliding door structure, the rotary cylinder at the end of the top rod and the roller design at the bottom of the sliding door effectively reduce the friction between the components, reduce wear, and make the sliding door open more smoothly.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 A spraying device for producing simulated fences is disclosed. The device includes a spraying machine body 1, flat spray nozzles 3, a drive assembly, sliding doors 4, and a top rod 5. A chain conveyor belt 2 is located at the bottom of the spraying machine body 1, with its top extending through the bottom of the machine body 1. Vertically positioned flat spray nozzles 3 are symmetrically arranged inside the machine body 1, located diagonally. A drive assembly is installed between the flat spray nozzles 3 and the machine body 1, driving the nozzles 3 to move towards each other for double-sided spraying of the simulated fence. Sliding doors 4 are symmetrically installed at both ends of the machine body 1 to prevent the sprayed material from spreading outwards. The chain conveyor belt 2... The outer wall is provided with top rods 5 at equal intervals for driving the sliding door 4 to move in opposite directions. The driving components include: motor 6, gear 7 and rack 8. The motor 6 is fixedly installed on the top of the spraying machine body 1. The output end of the motor 6 extends into the interior of the spraying machine body 1 and is fixedly connected to the gear 7. The rack 8 is meshed on both sides of the gear 7. The top of the interior of the spraying machine body 1 is fixedly connected to the protective cover 9. The rack 8 is slidably connected to the inner wall of the protective cover 9. The middle of the opposite side of the rack 8 is fixedly connected to the connecting rod 10. The bottom of the connecting rod 10 is fixedly connected to the corresponding flat spray nozzle 3. The interior of the spraying machine body 1 is symmetrically fixedly connected to the slide rail 11 parallel to the rack 8. The bottom of the connecting rod 10 is slidably connected to the inner wall of the corresponding slide rail 11.

[0028] It should be noted that: motor 6 is a forward and reverse motor, which makes the flat spray nozzle 3 circulate inside the sprayer body 1 to spray the fence to be sprayed; the bottom of the sprayer body 1 is provided with a clearance groove to allow the support rod 12 to pass through; in the structure of the sliding door 4, the design of the rotating cylinder at the end of the top rod 5 and the roller at the bottom of the sliding door 4 can effectively reduce the friction between the parts, reduce the degree of wear, and make the opening of the sliding door 4 smoother.

[0029] Please see Figure 2 , Figure 3 and Figure 4Support rods 12 are fixedly connected at equal intervals to the outer wall of the chain conveyor belt 2. Each pair of adjacent support rods 12 forms a group for fixing the fence to be sprayed. The outer wall of each pair of adjacent support rods 12 at the feeding end away from the chain conveyor belt 2 is fixedly connected to the corresponding top rod 5. The two ends of the spraying machine body 1 are provided with mounting grooves 13. Springs 14 are fixedly connected to the inner wall of the mounting grooves 13. The opposite side of the sliding door 4 is fixedly connected with a crossbar 15 corresponding to the mounting groove 13. The diameter of the crossbar 15 is smaller than the diameter of the corresponding mounting groove 13. The bottom of the side of the sliding door 4 near the feeding end is fixedly connected with a trapezoidal block 16 corresponding to the top rod 5. Friction blocks are provided at equal intervals on the outer wall of the crossbar 15. The friction force between the crossbar 15 and the corresponding mounting groove 13 is less than the elastic force of the spring 14. The end of the top rod 5 is rotatably connected with a rotating cylinder. Rollers are symmetrically rotatably connected to the bottom of the sliding door 4.

[0030] It should be noted that when the crossbar 15 fixedly connected to one side of the sliding door 4 is inserted into the mounting groove 13 inside the spraying machine body 1, the end of the crossbar 15 compresses the spring 14, causing it to compress and store force. As the chain conveyor belt 2 runs, the sliding door 4 is fully opened. At this time, the fence to be sprayed placed on the support rod 12 begins to enter the spraying machine body 1. Since the outer wall of the crossbar 15 is provided with friction blocks at equal intervals, and the friction between the crossbar 15 and the corresponding mounting groove 13 is less than the elastic force of the spring 14, the sliding door 4 will not immediately close due to the elastic force of the spring 14 after it is fully opened. Instead, the spring 14 releases its elastic force to push the crossbar 15 to slide slowly in the mounting groove 13, thereby causing the sliding door 4 to close slowly. After the fence to be sprayed has completely entered the spraying machine body 1, the crossbar 15 on one side of the sliding door 4 disengages from the mounting groove 13, and the sliding door 4 is in the closed state.

[0031] The working principle of the spraying device for producing simulated fences provided by this utility model is as follows:

[0032] First, the prefabricated simulated fence is placed on the support rod 12 near the loading end of the chain conveyor belt 2. Then, the chain conveyor belt 2 is started, and the simulated fence to be sprayed moves with the operation of the chain conveyor belt 2. Under the operation of the chain conveyor belt 2, the top rod 5, which is fixedly connected to the outer wall of the support rod 12 that supports the simulated fence to be sprayed and is located away from the loading end, first contacts the trapezoidal block 16 installed on one side of the sliding door 4. The rotating cylinder installed at the end of the top rod 5 can reduce the friction between it and the trapezoidal block 16. As the chain conveyor belt 2 runs, the trapezoidal block 16 is squeezed by the top rod 5, causing the symmetrically arranged sliding door 4 to slide to both sides inside the spraying machine body 1 and gradually open. When the crossbar 15 fixedly connected to one side of the sliding door 4 is inserted into the opening in the spraying machine body 1... When the horizontal bar 15 is in the mounting groove 13, the end of the horizontal bar 15 squeezes the spring 14, compressing and storing force. As the chain conveyor belt 2 runs, the sliding door 4 is fully opened. At this time, the fence to be sprayed placed on the support rod 12 begins to enter the spraying machine body 1. Since the outer wall of the horizontal bar 15 is provided with friction blocks at equal intervals, and the friction between the horizontal bar 15 and the corresponding mounting groove 13 is less than the elastic force of the spring 14, the sliding door 4 will not immediately close due to the elastic force of the spring 14 after it is fully opened. Instead, the spring 14 releases its elastic force to push the horizontal bar 15 to slide slowly in the mounting groove 13, thereby causing the sliding door 4 to close slowly. After the fence to be sprayed has completely entered the spraying machine body 1, the horizontal bar 15 on one side of the sliding door 4 disengages from the mounting groove 13, and the sliding door 4 is in the closed state.

[0033] Once the fence to be sprayed is fully inside the spraying machine body 1, the chain conveyor belt 2 stops running. At this time, the spraying machine body 1 starts, and the mist coating sprayed from the flat spray nozzles 3 symmetrically arranged inside begins the spraying operation on the fence to be sprayed.

[0034] At the same time, the motor 6 installed on the top of the sprayer body 1 starts, and the gear 7 fixedly connected inside the sprayer body 1 with its output end starts to rotate with the start of the motor 6. The racks 8 symmetrically meshed on both sides of the gear 7 move towards each other. The racks 8 are slidably installed inside the protective cover 9 fixedly connected to the top of the sprayer body 1, reducing the impact of atomized particles inside the sprayer on the drive components. The movement of the racks 8 drives the connecting frame fixedly connected in the middle to start moving. The bottom of the connecting frame is fixedly connected to the flat spray nozzle 3. Therefore, the flat spray nozzles 3, which are diagonally distributed inside the sprayer body 1, start to move towards each other with the movement of the racks 8, and spray both sides of the fence to be sprayed at the same time, which greatly improves the spraying efficiency. The bottom end of the connecting frame is slidably connected to the slide rail 11 installed inside the sprayer body 1, ensuring the stability of the flat spray nozzle 3 during the movement.

[0035] After one spraying cycle is completed, motor 6 stops running, and chain conveyor belt 2 restarts, transporting the sprayed fence to the material feeding end. During this process, the top rod 5 fixed to the outer wall of one of the support rods 12 pushes open the sliding door 4 near the material feeding end of the spraying machine body 1. Similarly, the trapezoidal block 16 on one side of the sliding door 4 is squeezed by the top rod 5, causing the sliding door 4 to move to both sides. The crossbar 15 on one side of the sliding door 4 inserts into the corresponding mounting slot 13 and compresses the spring 14 to store force, waiting for the top rod to be pushed open. When rod 5 disengages from trapezoidal block 16, sliding door 4 opens fully. One end of the painted fence extends out of the spraying machine body 1 under the operation of the material conveyor belt. At this time, spring 14 inside mounting groove 13 releases its elastic force. Due to the action of friction block on the outer wall of crossbar 15, crossbar 15 is pushed to slide slowly in mounting groove 13 until the painted fence leaves the inside of spraying machine body 1. The next set of fences to be painted repeats this step. After entering the inside of spraying machine body 1, motor 6 reverses and drives flat spray nozzle 3 to perform spraying operation.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
