Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning processing technology, and in particular to a drying device for processing air conditioning injection molded parts. Background Technology
[0002] Injection molded parts refer to all injection molded products produced by injection molding machines, including various packaging materials and parts. They are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Drying ovens are used in factories and research institutions for drying polymer materials, curing resins, and in processes such as pharmaceuticals, painting, electronics, electroplating, printing baking, drying injection molded parts, drying motors, drying transformers, industrial heat treatment, sterilization, and heating and insulation.
[0003] For example, Chinese utility model patent application number 202123033882.6 discloses a processing and drying device for air conditioner injection molded parts, including: a drying cabinet body with a cabinet door rotatably connected to its surface, and casters installed at the bottom of the drying cabinet body; a protective plate, which runs through the interior of the drying cabinet body, and has grooves inside, and is made of transparent PVC material; a locking spring is installed inside the drying cabinet body, and one end of the locking spring is connected to a locking pin. In this processing and drying device for air conditioner injection molded parts, by moving a lever, the locking pin retracts into the interior of the drying cabinet body, releasing the restriction on the protective plate. After the protective plate slides, it can cover the control panel of the device, thereby preventing accidental contact. Furthermore, by installing cleaning strips between the cleaning strips and connecting columns, two sets of cleaning strips can clamp the sides of the heat dissipation plate. When the cleaning strips are moved, the brushes on the cleaning strips can clean the heat dissipation holes, thereby preventing dust accumulation from affecting heat dissipation.
[0004] The aforementioned patent requires that the injection molded parts be placed on a rack before drying. However, the spacing between the racks cannot be adjusted. If a large injection molded part is processed, it cannot be placed on the rack because its size is larger than the spacing between the racks. If a small injection molded part is processed, there will be a large amount of extra space between the racks, resulting in low space utilization. This needs to be improved. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drying device for air conditioning injection molded parts.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for air conditioning injection molded parts, comprising a drying cabinet body, a fixed slide rail fixedly installed at the bottom of the inner wall of the drying cabinet body, a driving component provided on the fixed slide rail, two guide rods fixedly connected between the top and bottom of the inner wall of the drying cabinet body, the fixed slide rail fixedly sleeved on the outer surface of the two guide rods, three sets of moving components provided between the outer surfaces of the two guide rods, each moving component including a moving slide rail movably sleeved on the outer surface of the two guide rods, a limiting rod fixedly connected inside the moving slide rail, two sliders slidably installed outside the limiting rods, a scissor lift component provided between the two sliders, two support rods fixedly connected to the back of both the fixed slide rail and the moving slide rail, the supporting rods having a limiting component inside, and the limiting components in each set of support rods being symmetrically arranged.

[0010] The scissor lift assembly includes a first scissor bar and a second scissor bar. The first scissor bar and the second scissor bar intersect and are hinged at the middle. The upper ends of the first scissor bar and the upper ends of the second scissor bar are respectively hinged to the left and right sliders. The dimensions of the first scissor bar and the second scissor bar are adapted to the length of the slide rail.
[0011] As a further description of the above technical solution:
[0012] In the topmost set of scissor lift assemblies, the lower ends of the first and second scissor arms are respectively hinged to two sliders in the next set of moving assemblies, and in the bottommost set of scissor lift assemblies, the lower ends of the first and second scissor arms are respectively hinged to two threaded blocks.

A torsion spring is fixedly connected between the handle and the support rod and located on the outer surface of the rotating shaft. A limiting groove and a sliding groove are formed on the support rod. A rotating block is fixedly connected to the rotating shaft. A limiting block is fixedly connected to one side of the rotating block. The handle and the limiting block are in different directions on the same axis. When installed, the torsion spring ensures that the handle faces outward from the drying cabinet in the normal state, and the limiting block faces the direction of the placement plate.
[0015] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:
[0022] 1. Compared with existing technologies, this air conditioner injection molding part processing and drying device, by starting the drive motor, the output end of the drive motor rotates counterclockwise, indirectly driving each moving slide rail and placement plate to move upward synchronously, thereby increasing the distance between the placement plates, so that larger injection molding parts can also be placed in the drying cabinet for processing. When processing smaller injection molding parts, the output end of the drive motor reverses, indirectly driving the placement plates to descend, thereby reducing the distance between the placement plates. By setting up support plates and U-shaped frames, two placement plates can be manually added, which can utilize the space remaining due to the descent of the original placement plates, improving the space utilization rate of the drying cabinet and indirectly improving the drying efficiency.
[0023] 2. Compared with the prior art, the air conditioner injection molding part processing and drying device uses a handle, torsion spring, rotating shaft, rotating block, limiting block, slide groove, and limiting groove in combination. When the placement plate is placed in through the slide groove, the handle is turned until the limiting block faces upward. After the rectangular groove on the placement plate moves to the limiting block, the handle is released. Under the elastic force of the torsion spring, the handle returns to its original position, thereby causing the limiting block to be locked into the rectangular groove of the placement plate, thus limiting the placement plate and preventing it from sliding.

[0032] 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.
[0033] Reference Figure 1-6 This utility model provides a drying device for air conditioner injection molded parts: it includes a drying cabinet body 1, a fixed slide rail 2 is fixedly installed on the bottom of the inner wall of the drying cabinet body 1, a driving component is provided on the fixed slide rail 2, two guide rods 3 are fixedly connected between the top and bottom of the inner wall of the drying cabinet body 1, the fixed slide rail 2 is fixedly sleeved on the outer surface of the two guide rods 3, three sets of moving components are provided between the outer surfaces of the two guide rods 3, the moving components include a moving slide rail 4 movably sleeved on the outer surface of the two guide rods 3, a limit rod 5 is fixedly connected inside the moving slide rail 4, two sliders 6 are slidably installed outside the limit rod 5, a scissor lift component is provided between the two sliders 6, two support rods 7 are fixedly connected to the back of both the fixed slide rail 2 and the moving slide rail 4, a limit component is provided inside the support rod 7, and a cabinet door 23 is hinged to the front of the drying cabinet body 1;
[0034] By starting the drive motor 8, the output end of the drive motor 8 rotates counterclockwise, indirectly driving each moving slide rail 4 and the placement plate 20 to move upward synchronously, thereby increasing the distance between the placement plates 20, so that larger injection molded parts can also be placed in the drying cabinet for processing. When processing smaller injection molded parts, the output end of the drive motor 8 reverses, indirectly driving the placement plate 20 to descend, thereby reducing the distance between the placement plates 20.
[0035] The drive assembly includes a drive motor 8 fixedly installed at one end of the fixed slide rail 2. The output end of the drive motor 8 is fixedly connected to a bidirectional threaded rod 9. The bidirectional threaded rod 9 is rotatably installed on the inner wall of the fixed slide rail 2. Two threaded blocks 10 are slidably installed inside the fixed slide rail 2, and both threaded blocks 10 are threaded onto the outer surface of the bidirectional threaded rod 9.
[0036] The scissor lift assembly includes a first scissor bar 11 and a second scissor bar 12. The first scissor bar 11 and the second scissor bar 12 cross each other and are hinged at the middle. The upper ends of the first scissor bar 11 and the upper ends of the second scissor bar 12 are respectively hinged to the left and right sliders 6. The scissor lift assembly, together with the moving assembly, can realize the synchronous and equidistant lifting of the moving slide rail 4.
[0037] In the topmost scissor lift assembly, the lower ends of the first scissor bar 11 and the second scissor bar 12 are respectively hinged to two sliders 6 in the next set of moving assemblies, and in the bottommost scissor lift assembly, the lower ends of the first scissor bar 11 and the second scissor bar 12 are respectively hinged to two threaded blocks 10.
[0038] The limiting assembly includes a rotating shaft 13 rotatably installed inside the support rod 7. One end of the rotating shaft 13 rotatably passes through the support rod 7 and extends to the outside of the support rod 7. A handle 14 is fixedly connected to the end of the rotating shaft 13 located outside the support rod 7. A torsion spring 24 is fixedly connected between the handle 14 and the support rod 7 and located on the outer surface of the rotating shaft 13. A limiting groove 15 and a sliding groove 16 are provided on the support rod 7. A rotating block 17 is fixedly connected to the rotating shaft 13. A limiting block 19 is fixedly connected to one side of the rotating block 17. A placement plate 20 is slidably connected between the sliding grooves 16 of the two support rods 7. A rectangular groove 21 is provided on both sides of the placement plate 20.
[0039] By using the handle 14, torsion spring 24, rotating shaft 13, rotating block 17, limiting block 19, sliding groove 16, and limiting slot 15 in cooperation, when the placement plate 20 is placed in through the sliding groove 16, the handle 14 is rotated until the limiting block 19 faces upward. After the rectangular slot 21 on the placement plate 20 moves to the limiting block 19, the handle 14 is released. Under the elastic force of the torsion spring 24, the handle 14 returns to its original position, thereby causing the limiting block 19 to be engaged in the rectangular slot 21 of the placement plate 20, thus limiting the placement plate 20 and preventing it from sliding.
[0040] Two support plates 22 are fixedly connected to the top of the left and right sides of the inner wall of the drying cabinet body 1. A U-shaped frame 18 is fixedly connected to the side of the support plate 22 away from the drying cabinet body 1. By setting up the support plate 22 and the U-shaped frame 18, two placement plates 20 can be manually added, which can make use of the space left by the original placement plates 20 being lowered, thereby improving the space utilization rate of the drying cabinet and indirectly improving the drying efficiency.
[0041] Working principle: When it is necessary to dry the air conditioner injection molded parts, first determine the size of the injection molded parts to be processed. If the size of the injection molded parts is large, rotate the two uppermost handles 14 so that the two limit blocks 19 rotate to face upward. At this time, the limit blocks 19 lose their limiting function on the placement plate 20. Then remove the placement plate 20, and the handles 14 reset under the action of the torsion spring 24.
[0042] Then, the drive motor 8 is started. The output end of the drive motor 8 rotates counterclockwise, which drives the bidirectional threaded rod 9 to rotate counterclockwise. Under the limiting action of the fixed slide rail 2 on the two threaded blocks 10, the two threaded blocks 10 move towards each other, pushing the lower ends of the first scissor bar 11 and the second scissor bar 12 closer to each other. Under the limiting action of the guide rod 3 on the moving slide rail 4, the slider 6 and the moving slide rail 4 move upward, so that the two moving slide rails 4 move upward synchronously. After the interval between the two adjacent placement plates 20 is sufficient to place the injection molded part, the drive motor 8 is turned off.
[0043] Next, take out the placement plate 20 one by one, place the injection molded part on the placement plate 20, and then place the placement plate 20 into each set of slide grooves 16 from bottom to top. At the same time, rotate the handles 14 on both sides so that the limiting block 19 faces upward. When the rectangular groove 21 of the placement plate 20 moves to the limiting block 19, release the handle 14 so that the handle 14 is reset under the elastic force of the torsion spring 24 and is locked into the rectangular groove 21, thereby restricting the movement of the placement plate 20. Then close the cabinet door 23 and start the drying cabinet to process the injection molded part.
[0044] To process smaller injection molded parts, start the drive motor 8. The output of the drive motor 8 reverses, indirectly causing each placement plate 20 to move down, thereby reducing the gap between each placement plate 20. Then, add two more placement plates 20 whose size matches the U-shaped frame 18. Insert the newly added placement plates 20 into the U-shaped frame 18, thereby utilizing the extra space created by the downward movement of the original placement plates 20 and improving the space utilization rate of the drying cabinet.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
