[0032] The present invention will be further described with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 4The utility model shows a drying device for the production of thermoplastic elastomers, comprising a blast bellows body 1, wherein a drying chamber 11 is provided inside the blast bellows body 1, and a water outlet pipe 14 is provided at the bottom; a material receiving roller 2 for placing thermoplastic elastomer is detachably mounted inside the drying chamber 11, wherein a material port 23 is provided at one end of the material receiving roller 2 and the other end is closed; a plurality of scraping blades 22 are arranged equidistantly on the circumference of the material receiving roller 2; during assembly, the material port 23 of the material receiving roller 2 is installed toward the direction of the air outlet of the hot air blower 4; a limiting seat 17 is installed in the drying chamber 11 toward the direction of the air outlet of the hot air blower 4, a water-absorbing sponge 3 is detachably sleeved on the limiting seat 17, and an edge rubber ring 31 is provided on the outer side of the water-absorbing sponge 3. The outer edge of the rubber ring 31 cooperates with the inner side of the material port 23. When in use, the edge rubber ring 31 is embedded in the open end of the material port 23; a hot air blower 4 is provided on the outside of the blower box body 1, and the air inlet pipe 41 of the hot air blower 4 is inserted from the material port 23 of the material roller 2 and extends to the interior of the material roller 2. The air inlet pipe 41 is horizontally arranged in the drying chamber 11, and the air inlet front end of the air inlet pipe 41 is fixed in the limiting seat 17. A plurality of air outlet holes 42 are provided on the air inlet pipe 41. In order to facilitate the expansion of the air intake, an air outlet is provided at the end of the air inlet pipe 41. The end of the air inlet pipe 41 is provided with an air outlet; the material roller 2 is driven to rotate by the driving assembly 5; during rotation, the edge of the material roller 2 is limited by the limiting clamp 19 in the drying chamber 11.

[0034] A door handle 12 is provided on the outside of the blower bellows body 1, a support 13 is provided at the bottom of the blower bellows body 1, the length of the water outlet pipe 14 is shorter than the height of the support 13, and a switch valve 141 is provided on the water outlet pipe 14, and the water outlet is controlled by opening and closing the switch valve 141.

[0035] A handle 21 is mounted outwardly at the other end of the receiving roller 2 to facilitate manual operation during feeding and withdrawing.

[0036] The edge rubber ring 31 is annular and covers the outside of the water-absorbing sponge 3 and is made of rubber material. The end of the edge rubber ring 31 facing outward is set with an arc chamfer. Setting the edge rubber ring 31 as an arc chamfer can facilitate the engagement of the material port 23 of the material-receiving roller 2 with the edge rubber ring 31, so that the material port 23 is sealed to prevent the material from falling out of the material port during the rotation of the material-receiving roller 2. In addition, by setting the water-absorbing sponge 3, the moisture during drying can be adsorbed on the water-absorbing sponge 3 more quickly, and the water-absorbing sponge 3 can be processed at a single place after removing the material, and the dried water-absorbing sponge 3 can also be reused.

[0037] The limiting seat 17 is a ball bearing seat, which is convenient for the air inlet pipe to not roll due to the rolling of the material receiving roller 2 after installation, so that the air outlet and bulk material operations do not affect each other.

[0038] One end of the scraper blade 22 facing the rotation center is in a hook-like configuration, which facilitates breaking up the material, increases the contact area between the hot air and the surface of the material, and achieves a faster drying effect.

[0039] The side of the limiting clamp 19 facing the material roller 2 is set with an arc transition. The opening curvature of the limiting clamp 19 is consistent with the curvature of the material roller 2, which is convenient for support and limiting. The limiting clamp 19 consists of two pieces, which are symmetrically supported on both sides of the material roller 2. The ends of the limiting clamps 19 are welded in the drying chamber 11.

[0040] The blower box body 1 is provided with an air outlet on one side of the top facing the hot air blower 4, and clamping blocks 15 are provided in parallel on both sides of the air outlet. A slide plate 16 can be detachably pushed in between the clamping blocks 15, and a sealing ring 161 is provided on the edge and bottom of the slide plate 16. In this solution, the size of the air outlet can be controlled by controlling the distance between the sliding plate 16 and the clamping block 15, which is convenient for effectively removing moisture and heat from the cavity and convenient for taking out the absorbent sponge 3 for separate processing.

[0041] The driving assembly 5 includes a motor 51 installed on the outside of the blower bellows body 1, and the motor 51 is connected to the rotating shaft 53 in the drying chamber 11. The rotating shaft 53 is sleeved with a rotating gear 52, and the rotating gear 52 is arranged below the material receiving roller 2; when in use, the rotating gear 52 cooperates with the rack at the corresponding position on the outer surface of the material receiving roller 2. In this solution, the rotating gear 52 cooperates with the rack on the outer surface of the material receiving roller 2 to drive the material in the material receiving roller 2 to roll, thereby achieving the effect of bulk material.

[0042] The outward end of the material opening 23 is chamfered obliquely downward, which can better cooperate with the edge rubber ring on one hand, and on the other hand can guide the excess liquid in the water-absorbing sponge outward to prevent backflow and affect the dried material.

[0043] In actual work, first assemble the internal assembly according to the diagram, then put the material into the material receiving drum, and then press the material opening with the edge rubber ring at the position of the material receiving drum, so that the edge rubber ring and the material opening end are consistent. See the attached diagram for details. Figure 2Then, lower the head of the material receiving roller to keep the whole body horizontal. It should be noted here that the position of the rotating gear is different from the position of the limiting clamp. The two limiting clamps can be set in an open type in the drying chamber to facilitate the placement of the material receiving roller from top to bottom. The final effect is that the material receiving roller is supported by the limiting clamp and can be driven to rotate by the rotating gear; when drying, hot air is introduced through the hot air blower, and the air inlet pipe of the hot air blower conveys hot air into the material receiving roller. Since the air outlet holes on the air inlet pipe are evenly set, this can avoid the material close to the heat source from drying faster and the material far away from the heat source from drying slower, so as to achieve the effect of uniform heat transfer and uniform heating. In the process of hot air introduction, the driving motor in the driving assembly drives the rotating shaft to rotate, and the rotating gear on the rotating shaft cooperates with the rack on the outside of the material receiving roller to drive the material receiving roller to rotate, and the material in the material receiving roller is scraped The pieces are broken up to increase the drying area of ​​the material and the hot air, making the drying effect faster. At this time, since the air inlet pipe is extended to the material receiving drum through the ball bearing seat, it is not affected by the rotation of the material receiving drum. At the same time, the water vapor generated during drying is absorbed by the water-absorbing sponge, which is easier to clean and reuse when the water-absorbing sponge is peeled off later. In addition, during use, the clamping block and the slide plate at the air outlet can be adjusted according to the internal situation of the cavity to control the air outlet volume and effectively achieve the effect of dehumidification and heat dissipation. If there is more liquid on the material-absorbing sponge, it may fall into the drying cavity and eventually be discharged by the water outlet pipe. In order to facilitate the discharge of liquid, in actual conditions, the outward end of the material port can also be set to an oblique downward chamfer to prevent the liquid from flowing back into the dried material. After use, open the box door, take out the material receiving drum and unload it separately to complete the drying. It is simple to operate, has high drying efficiency and good drying effect.
