Description

Technical Field

[0001] This utility model belongs to the field of powder spraying equipment technology, specifically a powder spraying chamber with a recycling function. Background Technology

[0002] In most powder coating chambers, workers typically collect the powder that is not adhering to the workpiece surface for recycling and reuse. This not only reduces production costs but also minimizes environmental pollution. However, dust can adhere to the inner walls of the powder coating chamber, making it difficult to clean manually and recycle. Furthermore, the workflow in most powder coating chambers involves first accurately positioning the workpiece to ensure that the powder is evenly sprayed onto its surface. Positioning devices typically employ mechanical clamps, pneumatic clamps, electromagnetic clamps, etc., before the powder coating is applied by the powder coating equipment.

[0003] According to the authorized publication number CN210497005U, a powder spraying chamber is disclosed. It is equipped with a collection plate, collection holes, a collection seat, a filter barrel, and a fan. When collecting scattered powder, the fan drives air from the chamber to the collection chamber, and then from the collection chamber into the filter barrel. The air inlet pipe allows outside air to smoothly enter the chamber to balance the internal and external air pressure. Powder scattered on the collection plate enters the collection chamber along with the air under the action of airflow. The air in the collection chamber carries the powder into the filter barrel, which filters out the powder from the air and sends it out through an airlock. The filtered air is then sent out by the fan. No manual entry into the chamber is required for collection, making the collection operation more convenient and faster. A vibration motor is installed, which drives the collection plate to vibrate. During the vibration process, powder scattered on the collection plate that has not passed through the collection holes floats up due to the vibration. The floating powder can more easily follow the airflow and pass through the collection holes into the collection chamber, thus making the collection of powder on the collection plate more thorough.

[0004] The aforementioned patents have achieved the function of recycling, but the dust will stick to the inner walls on both sides of the powder spraying chamber, making it difficult to clean manually and recycle. Therefore, we propose a powder spraying chamber with recycling function. Utility Model Content

[0005] The purpose of this invention is to provide a powder spraying chamber with a recycling function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a powder spraying chamber with a recycling function, including a base, a powder spraying chamber cavity assembly is provided at the center of the top of the base, two sets of square shells with the same structure are provided on both sides of the top of the base adjacent to the powder spraying chamber cavity assembly, a vibration component with the same structure is provided at the bottom of the inner cavity of the two sets of square shells, and an air extraction pipe is provided at the bottom of the inner cavity of the powder spraying chamber cavity assembly, and the air extraction pipe extends out of the bottom of the base, one end of the air extraction pipe is connected to a cyclone separator, and a sealed opening and closing door is provided on one side of the outer wall of the powder spraying chamber cavity assembly.

[0007] Preferably, the vibration component includes a support base disposed on one side of the bottom of the inner cavity of the square housing, a motor mounted on the support base, a rotating disk connected to the actuator end of the motor, a connecting rod disposed on the outer wall of one side of the rotating disk away from the center, a connecting rod hinged to the connecting rod, a support slider hinged to one end of the connecting rod, matching support grooves slidably connected to the actuator ends of the support slider, and the upper and lower ends of the support grooves adjacent to the connecting rod are disposed at the top and bottom of the inner cavity of the square housing, a support cross plate disposed on one side of the support slider, three sets of air hammers with the same structure are arrayed on one side of the support cross plate, and a spring plate disposed at the bottom of the inner cavity of the square housing adjacent to the air hammers.

[0008] Preferably, the powder spraying chamber assembly includes a square powder spraying chamber located at the center of the top of the base. Two sets of identical powder spraying heads are connected to square grooves on one outer wall of the square powder spraying chamber. Two sets of rotating bearing seats are provided on the top outer wall of the square powder spraying chamber. A circular support seat is rotatably connected to the inner wall of each set of rotating bearing seats. A clamp is provided at the center of the bottom of the circular support seat, and a spraying plate is provided at the execution end of the clamp.

[0009] Preferably, the spring plate includes a first support vibration plate disposed at the bottom of the inner cavity of the square housing adjacent to the side of the air hammer, a plurality of springs with the same structure are uniformly arrayed on the outer wall of one side of the first support vibration plate, and a second support vibration plate is disposed at the other end of the springs, and the second support vibration plate is disposed at one end of the square powder spraying chamber.

[0010] Preferably, the outer wall of the circular support base, located away from the center, has a ring array of multiple air-blowing nozzles with the same structure.

[0011] Preferably, two sets of inclined guide plates with the same structure are symmetrically arranged on both sides of the bottom of the square powder spraying chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a vibration component in conjunction with a powder spraying chamber assembly to facilitate the cleaning and subsequent recycling of powder adhering to the inner walls on both sides of the powder spraying chamber. The vibration component consists of two identical sets, each driven by a motor to rotate a rotating disk connected to its actuator end. The rotation of the rotating disk causes a connecting rod located on the outer wall away from the center to rotate. Simultaneously, the rotation of the connecting rod causes a hinged connecting rod to rotate. A support slider hinged to one end of the connecting rod, when restricted by matching support grooves slidably connected to the actuator ends on both sides, transforms into a linear reciprocating motion of the support slider within the inner wall of the actuator end of the support groove. This linear reciprocating motion of the support slider also causes a support plate on one side and three sets of identical air hammers arranged in an array on one side of the support plate to perform a linear reciprocating motion downwards. Furthermore, the hammering force of the air hammers during operation can be transmitted to the interior of the first support vibration plate. Multiple springs of the same structure are evenly arrayed on the outer wall of one side of the first support vibration plate, and the other end of each spring is... The second supporting vibrating plate further improves vibration transmission and ensures uniform vibration distribution. The spring's cushioning effect reduces noise from the air hammer's impact and allows the hammering force on the first supporting vibrating plate to be more effectively transmitted to the second supporting vibrating plate. The second supporting vibrating plate is located at one end of the square powder spraying chamber, causing the powder adhering to it to vibrate and fall off. This facilitates linear reciprocating vibration transmission and generates sufficient force for firmly adhered powder. Two sets of rotating bearing seats on the outer wall of the top of the square powder spraying chamber facilitate the even rotation of the inner wall. The circular support base is rotated for adjustment. The rotation of the circular support base causes the clamp located at the bottom center to rotate. The rotation of the clamp causes the spraying plate located at the execution end to rotate for adjustment. Two sets of powder spraying heads with the same structure are provided on the outer wall of one side of the square powder spraying chamber and are connected to the square groove to facilitate the powder spraying equipment to be connected to the inner cavity of the square powder spraying chamber for powder spraying. Multiple air blowing nozzles with the same structure are arranged in a ring on the outer wall of one side of the circular support base away from the center position to blow the residual powder on the spraying plate away from the inclined guide plate at the bottom for subsequent recycling.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As mentioned in the background section, while existing technologies have achieved recycling in the aforementioned patents, the dust adheres to the inner walls of both sides of the powder spraying chamber, making manual cleaning and subsequent recycling difficult. Therefore, we propose a powder spraying chamber with recycling capabilities. This utility model provides a technical solution: it includes a base 1, a powder spraying chamber assembly 2 located at the center of the top of the base 1, two sets of identical square shell covers 4 adjacent to both sides of the top of the base 1 and the powder spraying chamber assembly 2, each set having a vibration component 7 of identical structure at the bottom of its inner cavity, and an exhaust pipe 6 located at the bottom of the inner cavity of the powder spraying chamber assembly 2, extending from the bottom of the base 1. One end of the exhaust pipe 6 is connected to a cyclone separator 3. A sealed opening and closing door 5 is located on one outer wall of the powder spraying chamber assembly 2. The vibration component 7, in conjunction with the powder spraying chamber assembly 2, facilitates the cleaning and subsequent recycling of the powder adhering to the inner walls of both sides of the powder spraying chamber.

[0017] Please see Figure 3-4As shown, the vibrating component 7 includes a support base 70 disposed on one side of the bottom of the inner cavity of the square housing 4. A motor 71 is mounted on the support base 70. The actuator end of the motor 71 is connected to a rotating disk 72. A connecting rod 73 is disposed on the outer wall of one side of the rotating disk 72 away from the center. A connecting rod 74 is hinged to the connecting rod 73. A support slider 75 is hinged to one end of the connecting rod 74. Matching support grooves 76 are slidably connected to the actuator ends of the support slider 75 on both sides. The upper and lower ends of the support grooves 76 adjacent to the connecting rod 74 are disposed at the top and bottom of the inner cavity of the square housing 4. A support cross plate 77 is disposed on one side of the support slider 75. Three sets of identical air hammers 78 are arrayed on one side of the supporting horizontal plate 77, and a spring plate 79 is arranged at the bottom of the square shell 4 adjacent to the air hammers 78. The vibrating components 7 consist of two sets of identical structures, each driven by a motor 71 to rotate a rotating disk 72 connected to its actuator end. The rotation of the rotating disk 72 causes a connecting rod 73 located on one side of the outer wall away from the center to rotate. Simultaneously, the rotation of the connecting rod 73 causes a hinged connecting rod 74 to rotate. A support slider 75, hinged to one end of the connecting rod 74, is slidably connected to matching support sliders on both sides of the actuator end. When the groove 76 is restricted, the support slider 75, which is hinged to one end of the connecting rod 74, transforms into a linear reciprocating motion moving up and down on the inner wall of the support groove 76. During this linear reciprocating motion, the support slider 75 drives a support plate 77 on one side and three sets of identical air hammers 78 arranged in an array on one side of the support plate 77 to perform a downward linear reciprocating motion. Furthermore, the hammering force of the air hammers 78 during operation can be transmitted from the first support vibration plate 791 to the interior of the wall. Multiple springs 792 with the same structure are evenly arrayed on the outer wall of one side of the first support vibration plate 791. The other end is provided with a second support vibration plate 793 to further improve the vibration transmission effect and uniformly distribute the vibration. The buffering effect of the spring 792 can reduce the noise generated by the hammer 78 and make the hammering force on the first support vibration plate 791 more effectively transmitted to the second support vibration plate 793. The second support vibration plate 793 is provided at one end of the square powder spraying chamber 21, so that the powder adhering to the second support vibration plate 793 is vibrated and falls off, which is conducive to linear reciprocating vibration transmission. For those firmly adhered powders, sufficient force is generated to make the powder fall to the bottom of the inner cavity of the square powder spraying chamber 21.

[0018] Please see Figure 2As shown, the powder spraying chamber assembly 2 includes a square powder spraying chamber 21 located at the center of the top of the base 1. Two sets of identical powder spraying heads are connected to square grooves 22 on one outer wall of the square powder spraying chamber 21. Two sets of rotating bearing seats 23 are located on the top outer wall of the square powder spraying chamber 21. A circular support seat 24 is rotatably connected to the inner wall of each of the two sets of rotating bearing seats 23. A clamp 25 is located at the center of the bottom of the circular support seat 24. A spraying plate 26 is mounted on the actuating end of the clamp 25. The powder spraying chamber 21 is positioned above the base of the square powder spraying chamber 21. Two sets of rotating bearing seats 23 are provided on the outer wall of the part to facilitate the rotation adjustment of the circular support seats 24 that are rotatably connected to the inner wall. The rotation of the circular support seats 24 drives the clamp 25 located at the bottom center to rotate. The rotation of the clamp 25 drives the spraying plate 26 located at the execution end to rotate and adjust. Furthermore, two sets of powder spraying heads with the same structure are provided on one side of the outer wall of the square powder spraying chamber 21 and connected to the square groove 22 to facilitate the powder spraying equipment to be connected to the inner cavity of the square powder spraying chamber 21 for powder spraying.

[0019] Please see Figure 3 As shown, the spring plate 79 includes a first support vibration plate 791 disposed at the bottom of the inner cavity of the square housing 4 adjacent to the side of the air hammer 78. A plurality of springs 792 with the same structure are evenly arrayed on the outer wall of one side of the first support vibration plate 791. A second support vibration plate 793 is disposed at the other end of the springs 792, and the second support vibration plate 793 is disposed at one end of the square powder spraying chamber 21. Furthermore, the hammering force of the air hammer 78 during operation can be transmitted to the interior of the wall of the first support vibration plate 791. The uniform array of a plurality of springs 792 with the same structure on the outer wall of one side of the first support vibration plate 791 and the second support vibration plate 793 disposed at the other end of the springs 792 facilitate further improvement of vibration transmission effect and uniform distribution of vibration. The buffering effect of the springs 792 can reduce the noise generated by the hammering of the air hammer 78 and make the hammering force received by the first support vibration plate 791 more effectively transmitted to the second support vibration plate 793. The second support vibration plate 793 is disposed at one end of the square powder spraying chamber 21, so that the powder adhering to the second support vibration plate 793 is vibrated off.

[0020] Please see Figure 2 As shown, a plurality of air-blowing nozzles 241 with the same structure are arranged in a ring on the outer wall of one side of the circular support base 24 away from the center. The plurality of air-blowing nozzles 241 with the same structure arranged in a ring on the outer wall of one side of the circular support base 24 away from the center facilitates the blowing of residual powder on the sprayed plate 26 away from the inclined guide plate 211 at the bottom.

[0021] Please see Figure 2As shown, two sets of identical inclined guide plates 211 are symmetrically arranged on both sides of the bottom of the square powder spraying chamber 21. The two sets of identical inclined guide plates 211 facilitate the flow of powder to the air extraction pipe 6 at the bottom of the square powder spraying chamber 21, and then the powder and air are separated by the cyclone separator 3, which facilitates subsequent recycling.

[0022] Working principle: Workers can easily adjust the rotation of circular support seats 24 rotatably connected to the inner wall of the square powder spraying chamber 21 by using two sets of rotating bearing seats 23 on the top outer wall. Locking nuts are installed on the rotating shafts of the rotating bearing seats 23. When rotation adjustment is needed, the locking nuts are loosened to allow the shaft to rotate freely. After adjusting to the appropriate position, the locking nuts are tightened, and the shaft is fixed by the friction between the nut and the shaft. This achieves the rotation adjustment of the bearing seats and, in turn, the rotation of the fixed circular support seats 24 drives the bottom center... The position is equipped with a clamp 25 for rotation. The rotation of the clamp 25 drives the spraying plate 26 at the execution end to rotate and adjust. Two sets of powder spraying heads with the same structure are provided on the outer wall of one side of the square powder spraying chamber 21 and connected to the square groove 22 to facilitate the powder spraying equipment to be connected to the inner cavity of the square powder spraying chamber 21 for powder spraying. Multiple air blowing nozzles 241 with the same structure are arranged in a ring on the outer wall of the circular support seat 24 away from the center to facilitate the blowing of the powder remaining on the spraying plate 26 to the inclined guide plate 211 at the bottom. When further cleaning the powder adhering to the inner walls on both sides of the square powder spraying chamber 21, the vibrating components 7 consist of two identical structures, each driven by a motor 71 to rotate a rotating disk 72 connected to the actuator end. The rotation of the rotating disk 72 causes a connecting rod 73 located on the outer wall away from the center to rotate. Simultaneously, the rotation of the connecting rod 73 causes a hinged connecting rod 74 to rotate. When a support slider 75 hinged to one end of the connecting rod 74 is restricted by matching support grooves 76 slidably connected to the actuator ends on both sides, the support slider 75 hinged to one end of the connecting rod 74... The block 75 transforms into a linear reciprocating motion up and down on the inner wall of the supporting slide 76. During this linear reciprocating motion, the supporting slide 75 drives a supporting horizontal plate 77 on one side and three sets of identical air hammers 78 arrayed on one side of the supporting horizontal plate 77 to perform a linear reciprocating motion downwards. Furthermore, the hammering force of the air hammers 78 during operation can be transmitted from the first supporting vibration plate 791 to the interior of the wall. Multiple springs 792 of the same structure are evenly arrayed on the outer wall of one side of the first supporting vibration plate 791, and a second supporting vibration plate 793 is provided at the other end of each spring 792 for further lifting. The system features high vibration transmission efficiency and uniform vibration distribution. The spring 792's buffering effect reduces noise generated by the air hammer 78's impact and allows the hammering force on the first support vibration plate 791 to be more effectively transmitted to the second support vibration plate 793. The second support vibration plate 793 is positioned at one end of the square powder spraying chamber 21, causing the powder adhering to it to vibrate and fall off. This facilitates linear reciprocating vibration transmission, generating sufficient force for firmly adhered powder to fall to the bottom of the square powder spraying chamber 21. The system is symmetrically positioned on both sides of the bottom of the square powder spraying chamber 21. Two sets of identical inclined guide plates 211 facilitate the flow of powder into the exhaust pipe 6 located at the bottom of the square powder spraying chamber 21. The powder and air are then separated by a cyclone separator 3. The cyclone separator 3 uses centrifugal force to separate the powder from the air. The powder-containing airflow enters the cyclone separator 3 tangentially at a certain speed through the exhaust pipe 6, forming a strong rotating airflow inside the separator. Under the action of centrifugal force, the powder particles are thrown against the wall of the separator and slide down the wall into the recovery container. The purified air is discharged from the center of the separator for subsequent recovery.
