Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a continuous dryer for the production of light stabilizers. Background Technology

[0002] Light stabilizers are additives used in polymer products (such as plastics, rubber, coatings, and synthetic fibers). They can shield or absorb ultraviolet energy, quench singlet oxygen, and decompose hydrogen peroxide into inactive substances. These functions allow polymers to eliminate or slow down photochemical reactions under light radiation, preventing or delaying photoaging and thus extending the lifespan of polymer products. Some light stabilizers are solid. During the production and processing of solid light stabilizers, some moisture may be adsorbed onto them. Therefore, light stabilizers need to be dried before packaging.

[0003] An existing patent (publication number: CN221325019U) discloses a continuous dryer for the production of light stabilizers, including a support plate. A first spring and a second spring are fixedly mounted on the top of the support plate. An inclined plate is fixedly mounted on the top of each of the first and second springs. A vibrator is fixedly mounted on the bottom of the inclined plate, and a baffle is fixedly mounted on the top of the inclined plate. The first and second springs cause the inclined plate to vibrate, allowing the light stabilizer to fall evenly onto a conveyor belt. The conveying assembly moves the light stabilizer to the right, and the drying assembly dries the light stabilizer. However, this technical solution still has shortcomings, specifically as follows:

[0004] The current device uses only the vibration of inclined plates to evenly distribute the light stabilizer onto the conveyor belt. However, some of the light stabilizer tends to clump together after processing, and when the light stabilizer clumps together into large pieces, it can affect the drying effect. Therefore, we propose a continuous dryer for light stabilizer production to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this invention is to provide a continuous dryer for the production of light stabilizers, which can solve the problem that existing devices only use inclined plate vibration to evenly sprinkle light stabilizers onto the conveyor belt, but some light stabilizers tend to clump together after processing, and when the light stabilizers clump together into large pieces, it can affect the drying effect of the light stabilizers.

[0007] To solve the above-mentioned technical problems, this utility model provides a continuous dryer for the production of light stabilizers, adopting the following technical solution: It includes a frame, inside which a conveyor belt is installed. Several grooves are formed on the outer walls of both ends of the left-side drive roller of the conveyor belt. A shaking plate is movably installed on the inner side of the frame. A dispersing roller is rotatably installed on the inner side of the shaking plate. Gears are fixedly installed at both ends of the dispersing roller extending out of the shaking plate. A toothed plate corresponding to the gear is fixedly installed on the inner side of the frame, meshing with the gear. An abutment plate is fixedly installed at both ends of the shaking plate, the lower end of which is inserted into the frame and slides against the outer wall of the conveyor belt drive roller. A dryer is fixedly installed on the inner side of the frame, above the conveyor belt.

[0008] By adopting the above technical solution, the light stabilizer is first continuously poured into the shaking plate, and then the conveyor belt is started to transport the light stabilizer discharged from the shaking plate to the bottom of the dryer. The light stabilizer is then dried by the dryer. When the conveyor belt is running, the drive roller rotates synchronously. At this time, the abutment rod is intermittently inserted into the groove, thereby causing the shaking plate to shake up and down continuously, and thus continuously dispersing the light stabilizer in the shaking plate.

[0009] Optionally, two slide grooves are provided on the inner side of the frame, and the two abutment plates are movably disposed in the two slide grooves.

[0010] By adopting the above technical solution, this solution uses a sliding groove to facilitate the limiting of the contact plate, so that the shaking plate can only shake up and down within the frame.

[0011] Optionally, the inside of the scattering plate is provided with a receiving groove, the scattering plate is inclinedly arranged in the frame, and a plurality of material discharge holes are provided at the bottom of the inner wall of the scattering plate.

[0012] By adopting the above technical solution, this solution facilitates the collection of light stabilizer through the receiving tank, and the light stabilizer is continuously moved downward by the inclined dispersing plate, and then discharged onto the conveyor belt through the discharge hole after being dispersed.

[0013] Optionally, the dispersing roller includes a round rod and a plurality of crushing rods, the round rod being rotatably disposed in a receiving groove, and the plurality of crushing rods being fixedly disposed on the outer wall of the round rod.

[0014] By adopting the above technical solution, when the shaking plate moves, it drives the dispersing roller to rotate synchronously. At this time, the toothed plate facilitates the rotation of the gear, the round rod and several crushing rods.

[0015] Optionally, the contact plate is T-shaped, and the contact plate is connected to the inner bottom wall of the slide groove by a spring.

[0016] By adopting the above technical solution, this solution uses a spring to easily pull the contact plate downward, thereby ensuring that the lower end of the contact plate is always in contact with the outer wall of the conveyor belt drive roller.

[0017] Optionally, the groove is positioned corresponding to the lower end of the contact plate, and the groove slides into contact with the lower end of the contact plate.

[0018] By adopting the above technical solution, when the drive roller of the conveyor belt rotates, the contact plate is continuously inserted into the groove, thereby facilitating the up-and-down movement of the shaking plate through the contact plate.

[0019] Optionally, the dryer includes a casing, a fan is installed inside the casing, a plurality of electric heating plates are installed at the bottom of the casing, and a plurality of diverter rods are fixedly installed at the bottom of the casing.

[0020] By adopting the above technical solution, this solution uses a fan to easily blow the heat generated by the electric heating plate onto the light stabilizer, thereby drying the light stabilizer through a high-temperature airflow.

[0021] Optionally, a scraper is inclinedly provided at the right end of the inner wall of the frame, and the upper end of the scraper slides against the outer wall of the conveyor belt.

[0022] By adopting the above technical solution, this solution uses a scraper plate to easily scrape off the light stabilizer adhering to the outer wall of the conveyor belt, thereby reducing the possibility of the dried light stabilizer adhering to the conveyor belt.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] The light stabilizer inside the shaker is broken up by the continuous up and down movement of the shaker plate. At the same time, the shaker plate moves and drives the dispersing roller to move synchronously. At this time, the toothed plate drives the gear and the dispersing roller to rotate, so that the light stabilizer inside the shaker plate is broken up again by the dispersing roller, thereby reducing the possibility of the light stabilizer agglomerating into lumps and affecting its drying effect.

[0025] The fan facilitates the blowing of heat generated by the electric heating plate onto the light stabilizer, thereby drying the light stabilizer through high-temperature airflow. The flow divider rod further diverts the light stabilizer on the conveyor belt, thus increasing the drying effect of the light stabilizer. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0032] Example 1, refer to Figures 1-3 In this embodiment, to address the problem that existing devices only use inclined plate vibration to evenly distribute the light stabilizer onto the conveyor belt, but some light stabilizer tends to clump together after processing, which can affect the drying effect, this invention discloses a continuous dryer for light stabilizer production.

[0033] The device includes a frame 1, characterized in that: a conveyor belt 2 is provided inside the frame 1, the conveyor belt 2 includes two drive rollers and a belt, the two drive rollers are driven by the belt, and the drive rod is driven by a motor, the conveyor belt 2 is existing equipment.

[0034] Several grooves 3 are provided on the outer walls of both ends of the left drive roller of the conveyor belt 2. A shaking plate 4 is movably arranged on the inner side of the frame 1. A receiving groove 41 is provided inside the shaking plate 4. The shaking plate 4 is inclined in the frame 1. Several discharge holes 42 are provided at the bottom of the inner wall of the shaking plate 4. The receiving groove 41 facilitates the collection of light stabilizer. The shaking plate 4 is inclined so that the light stabilizer moves downward continuously. Then, the dispersed light stabilizer is discharged onto the conveyor belt 2 through the discharge holes 42.

[0035] A dispersing roller 5 is rotatably mounted on the inner side of the dispersing plate 4. The two ends of the dispersing roller 5 extend out of the dispersing plate 4 and are fixedly mounted with gears 6. A toothed plate 7 corresponding to the gears 6 is fixedly mounted on the inner side of the frame 1. The toothed plate 7 meshes with the gears 6. The dispersing roller 5 includes a round rod 51 and several breaking rods 52. The round rod 51 is rotatably mounted in the receiving groove 41, and the several breaking rods 52 are fixedly mounted on the outer wall of the round rod 51. When the dispersing plate 4 moves, it drives the dispersing roller 5 to rotate synchronously. At this time, the toothed plate 7 facilitates the rotation of the gears 6, the round rod 51 and the several breaking rods 52, and then the breaking rods 52 facilitate the dispersing of the light stabilizer in the receiving groove 41.

[0036] Both ends of the shaking plate 4 are fixedly provided with abutment plates 8. The lower end of the abutment plate 8 is inserted into the frame 1 and slides against the outer wall of the conveyor belt 2 drive roller. The abutment plate 8 is T-shaped. The abutment plate 8 is connected to the inner bottom wall of the slide groove 11 by a spring 81. The spring 81 facilitates the pulling of the abutment plate 8 downward, thereby ensuring that the lower end of the abutment plate 8 is always in contact with the outer wall of the conveyor belt 2 drive roller.

[0037] Two slide grooves 11 are provided on the inner side of the frame 1, and two abutment plates 8 are movably arranged in the two slide grooves 11. The slide grooves 11 facilitate the limiting of the abutment plates 8, so that the shaking plate 4 can only shake up and down within the frame 1.

[0038] The position of the groove 3 corresponds to the position of the lower end of the contact plate 8. The groove 3 and the lower end of the contact plate 8 slide together. When the drive roller of the conveyor belt 2 rotates, it causes the contact plate 8 to continuously insert into the groove 3, thereby facilitating the up-and-down movement of the shaking plate 4 through the contact plate 8.

[0039] A dryer 9 is fixedly installed on the inner side of the frame 1. The dryer 9 is above the conveyor belt 2. The light stabilizer discharged from the shaking plate 4 is transported to the bottom of the dryer 9 through the conveyor belt 2, and then the light stabilizer is dried by the dryer 9.

[0040] The specific working principle is as follows: First, the light stabilizer is continuously poured into the shaking plate 4. Then, the conveyor belt 2 is started to transport the light stabilizer discharged from the shaking plate 4 to the bottom of the dryer 9. The light stabilizer is then dried by the dryer 9. When the conveyor belt 2 is running, the drive roller rotates synchronously. At this time, the abutment rod is intermittently inserted into the groove 3, which causes the shaking plate 4 to shake up and down continuously, thereby continuously breaking up the light stabilizer in the shaking plate 4. At the same time, when the shaking plate 4 moves, it drives the dispersing roller 5 to move synchronously. At this time, the toothed plate 7 drives the gear 6 to rotate with the dispersing roller 5, thereby breaking up the light stabilizer in the shaking plate 4 again through the dispersing roller 5, thereby reducing the possibility of the light stabilizer agglomerating and affecting its drying effect.

[0041] Example 2, refer to Figure 2Based on the same concept as in Embodiment 1 above, this continuous dryer for the production of light stabilizers further includes:

[0042] The dryer 9 includes a casing 91, a fan 92 is installed inside the casing 91, several electric heating plates 93 are installed at the bottom of the casing 91, and several diverting rods 94 are fixedly installed at the bottom of the casing 91.

[0043] The specific working principle is as follows: the heat generated by the electric heating plate 93 is blown onto the light stabilizer by the fan 92, thereby drying the light stabilizer by the high temperature airflow, and the light stabilizer on the conveyor belt 2 is diverted by the diverting rod 94, thereby increasing the drying effect of the light stabilizer.

[0044] Example 3, refer to Figure 2 Based on the same concept as in Embodiment 1 above, this continuous dryer for the production of light stabilizers further includes:

[0045] A scraper plate 12 is inclinedly provided on the right end of the inner wall of the frame 1, and the upper end of the scraper plate 12 slides against the outer wall of the conveyor belt 2.

[0046] The specific working principle is: the scraper plate 12 can easily scrape the light stabilizer attached to the outer wall of the conveyor belt 2, thereby reducing the possibility of the dried light stabilizer adhering to the conveyor belt 2.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
