Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning filter spraying technology, and in particular to an automotive air conditioning filter air purification material spraying device. Background Technology

[0002] Currently, in the production process of automotive air conditioning filters, air purification materials are usually sprayed onto the filter surface to improve their air purification performance. However, the air purification material spraying equipment for automotive air conditioning filters on the market has many shortcomings, which affect production efficiency and spraying quality.

[0003] Among them, the existing spraying device has an unreasonable spraying structure design, and the spraying range and angle of the spray gun are limited, making it difficult to achieve uniform spraying of all parts of the filter element. This results in insufficient coverage of purification material in some areas of the filter element, affecting the overall purification effect of the filter element.

[0004] To address these issues, we propose a spraying device for air purification materials in automotive air conditioning filters, which achieves uniform spraying. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an air purification material spraying device for automotive air conditioning filters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spraying device for air purification materials in automotive air conditioning filters includes: a spraying frame with a spray gun mounted on its inner top side, a support fixedly connected to the bottom of the spraying frame, the support being supported on the ground, and a lifting mechanism mounted on the support; and a conveyor belt with several equidistantly distributed buffer boxes mounted on it. Each buffer box contains a buffer assembly, and each buffer assembly contains a limit block. Positioning covers are fixedly connected to the side walls of adjacent limit blocks, and a stop is fixedly connected to the bottom of each positioning cover. The bottom of each stop corresponds to the lifting mechanism and is used to reciprocate and drive the positioning cover upwards.

[0008] Preferably, the lifting mechanism includes an eccentric disk that rotates on one side of the support, a linkage arm that is rotatably mounted on the outside of the eccentric disk via a first rotating shaft, and a pressing rod that is rotatably mounted on the other end of the linkage arm via a second rotating shaft. The pressing rod corresponds to the bottom of multiple abutment frames and can continuously squeeze and push the abutment frames.

[0009] Preferably, a limiting seat is fixedly connected to the top of the side wall of the bracket, and a through hole is provided in the middle of the limiting seat. The through hole is slidably connected to the extrusion rod, which can limit the extrusion rod in the vertical direction.

[0010] Preferably, a motor is fixedly installed on the side wall of the bracket, the motor drive output end is connected to the transmission shaft, and the other end of the transmission shaft is fixedly connected to the center of the eccentric disk.

[0011] Preferably, the buffer assembly includes a limiting rod fixedly connected to both sides of the inner cavity of the buffer box, a limiting block slidably installed on the limiting rod, and a first spring sleeved on both sides of the limiting rod. Each first spring is fixedly connected to the limiting block and the inner wall of the buffer box on both sides. The limiting block is slidably connected to the inner cavity of the buffer box, which allows the positioning cover to move up and down reciprocally.

[0012] Preferably, the conveyor belt is arranged in a ring structure, and the conveying surface of the conveyor belt is distributed along the vertical direction.

[0013] Preferably, each of the positioning covers is concave, and each of the positioning covers has piston holes at both ends on one side. A support column is slidably installed in each of the piston holes. An extrusion plate is fixedly connected to one side of each of two adjacent support columns. A second spring is sleeved on the outer wall of each support column. Each second spring is fixedly connected to the extrusion rod and the side wall of the positioning cover on both sides, respectively, so as to position the car air conditioning filter inside the positioning cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by installing a spray gun on the top inner side of the spraying frame, enables precise spraying of air purification materials onto automotive air conditioning filters on the conveyor belt, ensuring the accuracy and uniformity of the spraying. The bracket provides stable support for the spraying frame, ensuring the structural stability of the entire device during operation. The lifting mechanism, in conjunction with the support frame on the conveyor belt, can reciprocate to push the positioning cover upwards. Combined with the buffering effect of the buffer component, this allows the automotive air conditioning filter inside the positioning cover to reciprocate up and down during the spraying process, ensuring that all parts of the filter can fully contact the spraying material, improving the spraying effect and the utilization rate of the purification material.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A spraying device for air purification materials of automotive air conditioning filters includes: a spraying frame 1, a spray gun 16 disposed on the top inner side of the spraying frame 1, a bracket 11 fixedly connected to the bottom of the spraying frame 1, the bracket 11 being supported on the ground, and a lifting mechanism mounted on the bracket 11; it also includes a conveyor belt 12, on which several equidistantly distributed buffer boxes 13 are mounted, each buffer box 13 and the conveyor belt 12 having two corresponding screw holes, the corresponding two screw holes having internal threads for bolts, each buffer box 13 having a buffer assembly installed inside, each buffer assembly having a limit block 32, each adjacent limit block 32 having a positioning cover 14 fixedly connected to the side wall, each positioning cover 14 having a stop 15 fixedly connected to the bottom, and each stop 15 having a bottom corresponding to the lifting mechanism for reciprocating drive of the positioning cover 14 to move upward.

[0024] The spray gun on the top inner side of the spray frame 1 is used to spray air purification material onto the automotive air conditioning filter. The bracket 11 provides fixed support for the spray frame 1 to ensure the overall stability of the device during the spraying process. The conveyor belt 12 serves as a conveying carrier, and multiple positioning covers 14 evenly distributed on it are used to place the automotive air conditioning filter to be sprayed. When the device is running, the conveyor belt 12 moves the positioning covers 14 and the filter to below the spray gun. At this time, the lifting mechanism on the bracket 11 interacts with the abutment 15 at the bottom of the positioning cover 14. The lifting mechanism reciprocates to press the abutment 15, causing the positioning cover 14 to move upward. The buffer component in the buffer box 13 plays a buffering role during the movement of the positioning cover 14. When the pressing force of the lifting mechanism disappears, the buffer component drives the positioning cover 14 to reset, thereby realizing the up-and-down reciprocating movement of the filter in the positioning cover 14 during the spraying process, so that all parts of the filter can be sprayed evenly. At the same time, multiple positioning covers 14 can simultaneously convey and spray multiple filter elements, improving work efficiency.

[0025] Furthermore, the lifting mechanism includes an eccentric disk 2 that rotates on one side of the support 11, a linkage arm 21 that is rotatably mounted on the outside of the eccentric disk 2 via a first rotating shaft, and a pressing rod 22 that is rotatably mounted on the other end of the linkage arm 21 via a second rotating shaft. The pressing rod 22 corresponds to the bottom of multiple abutment frames 15 and can continuously squeeze and push the abutment frames 15. A motor 24 is fixedly mounted on the side wall of the support 11. The drive output end of the motor 24 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly connected to the center of the eccentric disk 2.

[0026] The eccentric disk 2 in the lifting mechanism rotates under the drive of external power. Since one end of the linkage arm 21 is rotatably connected to the outside of the eccentric disk 2 through the first rotating shaft, when the eccentric disk 2 rotates, it will drive the linkage arm 21 to make a circular motion around the first rotating shaft. This will cause the extrusion rod 22 connected to the other end of the linkage arm 21 through the second rotating shaft to move accordingly. Due to the eccentric setting of the eccentric disk 2, the extrusion rod 22 will generate a reciprocating motion in the up and down direction. The extrusion rod 22 corresponds to the bottom of multiple support frames 15. In this way, the extrusion rod 22 can continuously push the support frames 15 during the up and down movement, providing power for the reciprocating movement of the positioning cover 14, causing the filter element inside the positioning cover 14 to move up and down, ensuring uniform spraying.

[0027] When the motor 24 starts, its drive output end drives the transmission shaft to rotate, and the other end of the transmission shaft is fixedly connected to the center of the eccentric disk 2. Therefore, the transmission shaft will drive the eccentric disk 2 to rotate synchronously.

[0028] Furthermore, a limiting seat 23 is fixedly connected to the top of the side wall of the bracket 11. A through hole is provided in the middle of the limiting seat 23, and the through hole is slidably connected to the extrusion rod 22, which can limit the extrusion rod 22 in the vertical direction.

[0029] The limiting seat 23 on the top of the side wall of the bracket 11 serves to limit and guide the extrusion rod 22. The through hole in the middle of the limiting seat 23 is slidably connected to the extrusion rod 22. When the extrusion rod 22 moves up and down reciprocally under the drive of the linkage arm 21, the through hole restricts the displacement of the extrusion rod 22 in the horizontal direction and only allows the extrusion rod 22 to move in the vertical direction. This effectively prevents the extrusion rod 22 from deviating or shaking during the movement, ensuring that the extrusion rod 22 can always interact accurately with the support frame 15, ensuring the stable operation of the lifting mechanism, and thus ensuring the smooth progress of the spraying process.

[0030] Furthermore, the buffer assembly includes a limiting rod 3 fixedly connected to both sides of the inner cavity of the buffer box 13, a limiting block 32 slidably installed on the limiting rod 3, and a first spring 33 sleeved on both sides of the limiting rod 3. Each first spring 33 is fixedly connected to the limiting block 32 and the inner wall of the buffer box 13 on both sides. The limiting block 32 is slidably connected to the inner cavity of the buffer box 13, which can make the positioning cover 14 move up and down reciprocally.

[0031] The limiting rod 3 in the buffer assembly is fixed on both sides of the inner cavity of the buffer box 13. The limiting block 32 is slidably installed on the limiting rod 3, so that the limiting block 32 can only slide in the buffer box 13 along the axial direction of the limiting rod 3, which plays a guiding role. The first spring 33 on both sides of the limiting rod 3 is fixedly connected to the limiting block 32 and the inner wall of the buffer box 13, respectively. When the lifting mechanism squeezes the positioning cover 14 to move upward, the positioning cover 14 drives the limiting block 32 to slide upward along the limiting rod 3. At this time, the limiting block 32 will compress the upper first spring 33 and the lower first spring 33 will be stretched, and the first spring 33 will produce elastic deformation. When the squeezing force of the lifting mechanism disappears, the elastic potential energy of the first spring 33 is released, which drives the limiting block 32 to slide downward along the limiting rod 3 to reset, thereby resetting the positioning cover 14 and realizing the up and down reciprocating movement of the positioning cover 14. In this process, the elastic force of the first spring 33 makes the movement of the limiting block 32 and the positioning cover 14 more stable.

[0032] Furthermore, the conveyor belt 12 is arranged in a ring structure, and the conveying surface of the conveyor belt 12 is distributed in the vertical direction. Rollers are arranged on both sides of the conveyor belt 12. The conveyor belt 12 is driven by friction on the outside of the two rollers. The central shaft of one roller is connected to the motor drive end through a transmission shaft.

[0033] The conveyor belt 12 has a ring structure, which allows it to circulate. The automotive air conditioning filter to be sprayed is placed in the positioning cover 14 on the conveyor belt 12 and is continuously transported with the ring movement of the conveyor belt 12, realizing the circular transport of the filter and improving the transport efficiency. The transport surface of the conveyor belt 12 is distributed in the vertical direction, and the filter moves with the conveyor belt 12 in the vertical direction. In this way, during the spraying process, the spray gun can more easily spray the filter from different angles and save horizontal space, adapting to production environments with limited space.

[0034] In the automotive air conditioning filter air purification material spraying device, the conveyor belt 12 adopts a ring structure and the conveying surface is distributed in the vertical direction. The conveyor belt 12 itself has a preset structural size and load-bearing strength, and its overall volume and rigidity meet the conveying requirements under continuous operation conditions. The automotive air conditioning filter workpiece to be sprayed is positioned on the conveyor belt 12 by the positioning cover 14. The volume size of the workpiece is smaller than the conveying surface size of the conveyor belt 12, and the workpiece is relatively fixed to the conveyor belt 12 by the positioning cover 14 and the buffer assembly. When the conveyor belt 12 drives the workpiece to the outside of the rotating roller of the device (i.e., the annular corner transition area of ​​the conveyor belt 12), the rigid structure of the conveyor belt 12 itself can maintain its preset conveying trajectory on the outside of the rotating roller, and the workpiece is stably limited by the clamping and positioning structure formed by the extrusion plate 41, the support column 4 and the second spring 42 in the positioning cover 14.

[0035] Furthermore, each positioning cover 14 is concave in shape, and each positioning cover 14 has piston holes at both ends on one side. A support column 4 is slidably installed in each piston hole. An extrusion plate 41 is fixedly connected to one side of each pair of adjacent support columns 4. A second spring 42 is sleeved on the outer wall of each support column 4. Each second spring 42 is fixedly connected to the extrusion rod 22 and the side wall of the positioning cover 14 on both sides, thereby positioning the car air conditioning filter inside the positioning cover 14.

[0036] The positioning cover 14 is concave to facilitate the placement of the automotive air conditioning filter element for initial positioning. When the filter element is placed, it will press the extrusion plates 41 on both sides, causing the extrusion plates 41 to slide the support column 4 into the piston hole. At this time, the second spring 42 is compressed, generating elastic force. Under the action of the elastic force of the second spring 42, the extrusion plates 41 will press tightly against the filter element, thereby firmly positioning filter elements of different sizes in the positioning cover 14 and preventing the filter element from shaking or falling off during transportation and spraying.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
