Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and more specifically, to a spraying device and a spraying method for producing prison doors. Background Art

[0002] Prison doors, also known as cell doors or cell doors, are important passages connecting the detainees' living quarters with management passages, outdoor activity areas, and confinement rooms. The core function of these doors is to effectively resist opening by abnormal means within a specified time, thereby ensuring the safety and order of the prison. In order to achieve such high standards, prison doors are usually made of strong and durable materials such as steel to ensure their strength and durability.

[0003] However, we face a series of challenges when spraying these prison doors. Although the existing spraying equipment can fully cover the entire surface of the door through the rotary spraying technology to achieve the ideal spraying effect, in actual operation, in order to ensure that the paint can adhere firmly to the prison door and improve the processing quality of the prison door, we often need to polish the door first, apply putty and other tedious pre-treatment processes to increase its surface flatness and roughness.

[0004] The above-mentioned complicated process not only increases the difficulty and time cost of operation, but also reduces the coating efficiency. Moreover, if only the spraying device itself is relied on, it is difficult to ensure the quality after spraying and the adhesion effect of the coating. Therefore, the existing spraying device is difficult to achieve the ideal effect in terms of coating efficiency and coating quality. In view of this, we propose a spraying device and a spraying method for prison door production. Summary of the invention

[0028] A spraying method of a spraying device for producing prison doors, comprising the following steps:

[0029] S1. When in use, the prison door to be treated needs to be lifted by the lifting device and installed on the clamp, and then the position of the prison door can be adjusted accordingly by adjusting the lateral position of the clamp, and after the adjustment is completed, the cylinder can be started to spray the prison door;

[0030] S2. When sandblasting the prison door, the cylinders on both sides need to be controlled to synchronously push the protection frame downward. As the protection frame moves downward, the drive assembly will rotate counterclockwise due to contact with the tooth plate and drive the pressure assembly to run clockwise. At this time, the pressure assembly extracts the one-way valve gas and discharges it into the first box body when running clockwise, increasing the pressure in the first box body while discharging the stored sand in the first box body to pre-treat the prison door. After the spraying assembly moves horizontally to the bottom of the first slide slot, the sandblasting of the prison door is completed. Subsequently, the prison door needs to be painted. The pressure assembly is moved in the opposite direction by the cylinder, so that the pressure assembly moves upward. At this time, the driving assembly will rotate clockwise as it contacts the tooth plate and drive the pressure assembly to run counterclockwise. When the pressure assembly runs counterclockwise, the gas of the outer valve body of the supercharger is extracted and discharged into the second box. At the same time, the supercharger will synchronously drive the docking cover and the paint spray head to rotate through the docking joint, so that the paint in the second box is squeezed by the pressure accumulation and discharged horizontally along the paint spray head. At the same time, the paint spray head can spray the paint droplets falling on the workpiece on the surface of the workpiece through the centrifugal force and gravity generated during rotation.

[0031] S2.1. When sandblasting the prison door, the cylinders on both sides need to be controlled to synchronously push the protection frame downward. As the protection frame moves downward, the second gear will rotate counterclockwise due to contact with the tooth plate and drive the first gear and the supercharger to run clockwise. Since the docking head and the docking groove in the clockwise rotating state are in arc surface contact, the friction between the docking head and the docking groove is insufficient to drive the docking cover to rotate. The supercharger will also extract the gas from the one-way valve through the second output pipe and transport the gas into the first box body, squeezing and discharging the sand body in the first box body into the sandblasting box, and the pretreatment of the prison door is completed by sandblasting in a horizontal up and down movement manner;

[0032] S2.2, when spraying paint on the prison door, the cylinder moves the protection frame in the opposite direction so that the protection frame moves up. At this time, one of the second gears will rotate clockwise as it contacts the tooth plate and drive the supercharger to run counterclockwise. When the supercharger runs counterclockwise, the gas of the supercharger outer valve body is extracted and discharged into the second box body, and the butt joint in the counterclockwise rotating state is in contact with the vertical surface of the butt joint groove. At this time, the butt joint will synchronously drive the butt joint cover and the paint spray head to rotate, so that the paint spray head can complete the rotary spraying effect when the supercharger discharges paint through the second box body;

[0033] S3. When the protection frame moves downward, the second gear will contact the tooth plate, so that the screw rod rotates in the nut and pulls the multi-section telescopic rod to extend. When the screw rod moves to the extreme position, the second gear continues to rotate, so that the nut will rotate synchronously in the connecting sleeve through the mounting shell, and when the screw rod moves to the extreme position, the cleaning scraper will fit with the prison door, so that the device can spray the prison door and perform secondary cleaning of impurities or sand bodies adhered to the surface of the prison door at the same time, and when the protection frame moves upward, the screw rod rotates in the nut to push the multi-section telescopic rod to contract. Similarly, when the screw rod moves to the extreme position, it will accelerate the flow of air in front of the prison door through the blades.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention designs a cylinder, a pressure assembly, a driving assembly and a spraying assembly. When sandblasting the prison door, it is necessary to control the cylinders on both sides to synchronously push the protection frame downward. As the protection frame moves downward, the driving assembly will rotate counterclockwise as it contacts the tooth plate and drive the pressure assembly to run clockwise. At this time, the pressure assembly draws the one-way valve gas and discharges it into the first box body when running clockwise, increasing the pressure in the first box body while discharging the stored sand in the first box body to pre-treat the prison door. After the spraying assembly moves horizontally to the bottom of the first slide slot, the sandblasting of the prison door is completed. Subsequently, the prison door needs to be painted, and the pressure assembly is moved in the opposite direction by the cylinder to move the pressure assembly upward. At this time, the driving assembly will rotate clockwise as it contacts the tooth plate and drive the pressure assembly to run counterclockwise. When the component runs counterclockwise, the gas of the outer valve body of the supercharger is extracted and discharged into the second box body. At the same time, the supercharger will synchronously drive the docking cover and the paint spray head to rotate through the docking joint, so that the paint in the second box body is squeezed by pressure accumulation and discharged horizontally along the paint spray head. At the same time, the paint spray head can use the centrifugal force and gravity generated during rotation to spray the paint droplets falling on the workpiece onto the surface of the workpiece. This allows the device to complete the sandblasting and painting of the prison door only by controlling the up and down movement of the pressure component through the cylinder, which reduces the difficulty of actual use of the device. When spraying vertically, the sandblasting particles can quickly contact the surface to achieve a better coating coverage rate, thereby ensuring the effect of subsequent painting of the prison door. Spinning paint by rotary spraying can fully cover the surface of the prison door with paint, thereby ensuring the painting effect and improving the painting efficiency when the device is in use.

[0036] 2. The present invention also designs a second gear, a toothed plate, a supercharger, a one-way valve and a sandblasting head. When sandblasting the prison door, it is necessary to control the cylinders on both sides to synchronously push the protection frame downward. As the protection frame moves downward, the second gear will rotate counterclockwise as it contacts the toothed plate and drive the first gear and the supercharger to run clockwise. Since the docking head and the docking groove in the clockwise rotating state are in arc surface contact, the friction between the docking head and the docking groove is insufficient to drive the docking cover to rotate, and the supercharger will also extract the gas of the one-way valve through the second output pipe and transport the gas into the first box body, squeeze and discharge the sand body in the first box body into the sandblasting box, and complete the pretreatment of the prison door by sandblasting in a horizontal up and down movement manner, so that the device can complete the preliminary treatment of the prison door without additional personnel cooperation, and the roughness of the surface of the prison door can be improved after sandblasting, thereby ensuring the adhesion effect of the paint in the subsequent painting process, thereby ensuring the spraying efficiency of the device.

[0037] 3. The present invention also designs a cylinder, a supercharger, a docking joint, a docking cover and a paint spray head. When the prison door is sprayed with paint, the protective frame is moved upward by the cylinder in the reverse direction. At this time, one of the second gears will rotate clockwise as it contacts the tooth plate and drive the supercharger to run counterclockwise. When the supercharger runs counterclockwise, the gas of the outer valve body of the supercharger is extracted and discharged into the second box body, and the docking joint in the counterclockwise rotating state is in contact with the vertical surface of the docking groove. At this time, the docking joint will synchronously drive the docking cover and the paint spray head to rotate, so that the paint spray head can complete the rotary spraying effect when the supercharger discharges paint through the second box body, so that the device can complete the spraying of the prison door only by moving the pressure component upward, and because the device can automatically switch the spraying mode during the spraying process, the difficulty of using the device is reduced, and the rotary spraying mode further improves the spraying quality of the device.

When sandblasting the prison door, it is necessary to control the cylinders 206 on both sides to synchronously push the protection frame 202-1 downward. As the protection frame 202-1 moves downward, the drive assembly 203 will rotate counterclockwise as it contacts the tooth plate 201-5 and drive the pressure assembly 202 to run clockwise. At this time, the pressure assembly 202 extracts the gas from the one-way valve 202-503 when running clockwise and discharges it into the first box body 202-2, increasing the pressure in the first box body 202-2 while discharging the stored sand in the first box body 202-2 to pre-treat the prison door, and when the spray assembly 204 moves horizontally to the first box body 202-2, the pressure in the first box body 202-2 is increased. After the bottom of the slide 201-2, the sandblasting of the prison door is completed. Subsequently, the prison door needs to be painted. The pressure component 202 is moved in the opposite direction by the cylinder 206, so that the pressure component 202 moves up. At this time, the driving component 203 will rotate clockwise as it contacts the tooth plate 201-5 and drive the pressure component 202 to run counterclockwise. When the pressure component 202 runs counterclockwise, the gas of the outer valve body of the booster 202-3 is extracted and discharged into the second box body 202-501. At the same time, the booster 202-3 will synchronously drive the docking cover 202-703 and the paint spray head 204-301 to rotate through the docking head 202-702, so that the second box body 202-501 While the paint inside is extruded and discharged horizontally along the paint spray head 204-301 under pressure accumulation, the paint spray head 204-301 can spray the paint droplets falling on the workpiece onto the surface of the workpiece through the centrifugal force and gravity generated during rotation, so that the device only needs to control the up and down movement of the pressure component 202 through the cylinder 206 to complete the sandblasting and painting of the prison door, which reduces the difficulty of actual use of the device, and when spraying vertically, the sandblasting particles can quickly contact the surface to achieve a better coating coverage rate, thereby ensuring the effect of subsequent painting of the prison door, and spraying paint by rotary spraying can make the paint fully cover the surface of the prison door, thereby ensuring the painting effect and improving the painting efficiency when the device is used.

[0068] Working principle: This embodiment provides a spraying device and a spraying method for prison door production. When in use, the prison door to be processed needs to be lifted by a lifting device and then installed on the clamp 104. Then, the position of the prison door can be adjusted accordingly by adjusting the lateral position of the clamp 104. After the adjustment is completed, the cylinder 206 can be started to spray the prison door.

[0069] When sandblasting the prison door, it is necessary to control the cylinders 206 on both sides to synchronously push the protection frame 202-1 downward. As the protection frame 202-1 moves downward, the drive assembly 203 will rotate counterclockwise as it contacts the tooth plate 201-5 and drive the pressure assembly 202 to run clockwise. At this time, the pressure assembly 202 extracts the gas from the one-way valve 202-503 when running clockwise and discharges it into the first box body 202-2, increasing the pressure in the first box body 202-2 while discharging the stored sand in the first box body 202-2 to pre-treat the prison door. After the spraying assembly 204 moves horizontally to the bottom of the first slide chute 201-2, the sandblasting of the prison door is completed. Subsequently, the prison door needs to be painted, and the pressure assembly 206 moves in the opposite direction to The force component 202 causes the pressure component 202 to move upward. At this time, the driving component 203 will rotate clockwise as it contacts the tooth plate 201-5 and drive the pressure component 202 to run counterclockwise. When the pressure component 202 runs counterclockwise, the gas of the outer valve body of the supercharger 202-3 is extracted and discharged into the second box body 202-501. At the same time, the supercharger 202-3 will synchronously drive the docking cover 202-703 and the paint spray head 204-301 to rotate through the docking joint 202-702, so that the paint in the second box body 202-501 is squeezed and discharged horizontally along the paint spray head 204-301 under pressure accumulation. At the same time, the paint spray head 204-301 can fully spray the paint droplets falling on the workpiece on the surface of the workpiece through the centrifugal force and gravity generated during rotation;

[0070] When sandblasting the prison door, the cylinders 206 on both sides need to be controlled to synchronously push the protection frame 202-1 downward. As the protection frame 202-1 moves downward, the second gear 203-1 will rotate counterclockwise due to contact with the tooth plate 201-5 and drive the first gear 202-6 and the supercharger 202-3 to run clockwise. Since the docking head 202-702 and the docking groove 202-704 in the clockwise rotating state are in arc surface contact, The friction between the docking head 202-702 and the docking groove 202-704 is insufficient to drive the docking cover 202-703 to rotate, and the supercharger 202-3 will also extract the gas of the one-way valve 202-503 through the second output pipe 202-504 and transport the gas to the first box 202-2, squeeze and discharge the sand in the first box 202-2 into the sandblasting box 204-1, and complete the pretreatment of the prison door by sandblasting in a horizontal up and down movement;

[0071] When the prison door is sprayed with paint, the protection frame 202-1 is moved in the opposite direction by the cylinder 206, so that the protection frame 202-1 moves up. At this time, one of the second gears 203-1 will rotate clockwise as it contacts the tooth plate 201-5 and drive the supercharger 202-3 to run counterclockwise. When the supercharger 202-3 runs counterclockwise, the gas of the outer valve body of the supercharger 202-3 is extracted and discharged into the second box body 202-501, and the docking joint 202-702 and the docking groove 202-704 in the counterclockwise rotating state are in vertical contact. At this time, the docking joint 202-702 will synchronously drive the docking cover 202-703 and the paint spraying head 204-301 to rotate, so that when the supercharger 202-3 discharges paint through the second box body 202-501, the paint spraying head 204-301 can complete the rotary spraying paint effect;

[0072] When the protection frame 202-1 moves downward, the second gear 203-1 will contact the tooth plate 201-5, so that the screw rod 203-4 rotates in the nut 203-5 to pull the multi-section telescopic rod 203-3 to extend. When the screw rod 203-4 moves to the extreme position, the second gear 203-1 continues to rotate, so that the nut 203-5 will rotate synchronously in the connecting sleeve 203-601 through the mounting shell 203-602, and when ... When the cleaning scraper 203-9 is in the limit position, it will fit with the prison door, so that the device can perform secondary cleaning of impurities or sand adhering to the surface of the prison door while spraying the prison door, and when the protective frame 202-1 moves upward, the screw rod 203-4 will push the multi-section telescopic rod 203-3 to contract when it rotates in the nut 203-5. Similarly, when the screw rod 203-4 moves to the limit position, it will accelerate the flow of air in front of the prison door through the blade 203-8.
