Further, the stopper 14 has a straight-line structure.
Further, the elastic component 9 is a spring.
The working principle of the utility model is as follows:
when the air heater works, the air heater is started, and the generated hot air is guided into the drying cylinder 2 through the air outlet 7 of the hot air pipe 6; the hot melt adhesive particles to be dried are put into the drying cylinder 2 through the feeding hole 4, as embodiment 1, the driving component can select the rotating motor to realize that the rotating motor belongs to a mature device in the technical field, so the drawing no longer shows that the rotating motor can drive the rotating shaft 3 to drive the fixing frame 8 to rotate, and the connecting plate 11 is connected to one side of the fixing frame 8, which is away from the rotating shaft 3, through the elastic component 9, and the rubber scraping plate 10 is arranged on the connecting plate 11, so when the rotating shaft 3 rotates, the connecting plate 11 and the rubber scraping plate 10 can be driven to rotate, and hot air blown out from the hot air pipes 6 in different directions in the drying cylinder 2 forms a thermodynamic circulation in the drying cylinder 2 under the stirring of the fixing frame 8 and the rubber scraping plate 10, so the hot melt adhesive particles are circularly dried. In order to solve the problem of hot melt adhesive particles adhered to the inner side wall of the drying cylinder 2, an elastic component 9 is arranged between a connecting plate 11 and a fixing frame 8, namely, when a rotating shaft 3 generates centrifugal force in the rotating process, under the action of the centrifugal force, the connecting plate 11 and a rubber scraper 10 can stretch a spring to deform the rubber scraper 10, so that the rubber scraper 10 is continuously close to and is adhered to the inner side wall of the drying cylinder 2, and then the rotating shaft 3 drives the rubber scraper 10 to scrape off the hot melt adhesive particles adhered to the inner side wall of the drying cylinder 2 under the rotating condition to participate in stirring and drying. Compared with the thrust of the bristles to the hot melt adhesive particles in the rotating process, the rigidity of the rubber scraping plate 10 is higher than that of the bristles, and the thrust of the rubber scraping plate 10 to the hot melt adhesive particles when contacting the inner side wall of the drying cylinder 2 is higher than that of the bristles, so that the hot melt adhesive particles adhered to the inner side wall of the drying cylinder 2 can be scraped off, and the rubber scraping plate 10 does not scratch the coating on the inner side wall of the drying cylinder 2 when acting on the inner side wall of the drying cylinder 2, so that the drying quality of the hot melt adhesive is improved. In addition, as the elastic component 9 is arranged between the connecting plate 11 and the fixing frame 8, when hot melt adhesive particles in the drying cylinders 2 with different diameters are required to be dried, the connecting plate 11 and the rubber scraping plate 10 can stretch the elastic component 9 to make an adaptive deformation under the action of centrifugal force, so that the hot melt adhesive particles on the inner side walls of the drying cylinders 2 with different diameters can be scraped; however, since the deformation amount of the elastic member 9 has a limit value, it is only suitable for the drying operation of the drying cylinders 2 having partially different diameters.
When the hot air pipe 6 is installed, it should be noted that the hot air pipe 6 needs to be ensured to be completely located in the installation groove 5, and the hot air pipe 6 cannot extend out of the installation groove 5, otherwise, when the rubber scraper 10 rotates, the hot air pipe 6 extending out of the installation groove 5 can cause motion interference. In the running test process of the dryer, as the elastic component 9 is easy to generate deformation under the action of external force, the rubber scraper 10 is found to be easy to generate dislocation with the fixing frame 8 (when the fixing frame 8 rotates to a non-vertical state, the rubber scraper 10 and the connecting plate 11 can move downwards due to self gravity), so that the contact area between the rubber scraper 10 and the inner side wall of the drying cylinder 2 is reduced, and the scraping effect of hot melt adhesive particles adhered to the inner side wall of the drying cylinder 2 is influenced. Therefore, a reinforcing rod 12 is arranged between the connecting plate 11 and the fixed frame 8, when the rotating shaft 3 rotates, the connecting plate 11 and the rubber scraping plate 10 stretch the elastic component 9 under the action of centrifugal force, the reinforcing rod 12 is synchronously pulled, at the moment, one end of the reinforcing rod 12 moves in the movable groove 13, when the anti-falling piece 15 connected to the reinforcing rod 12 moves to the notch of the movable groove 13 to abut against the stop piece 14, the reinforcing rod 12 stops moving, the reinforcing rod 12 has a guiding effect on the movement track of the connecting plate 11 and the rubber scraping plate 10, and the reinforcing rod 12 has certain rigidity, so that the phenomenon that the reinforcing plate and the rubber scraping plate 10 move downwards under the action of gravity and are displaced from the fixed frame 8 can be prevented. In addition, the stop piece 14 is arranged at the notch of the movable groove 13, and one end of the reinforcing rod 12 can be effectively prevented from being separated from the movable groove 13 in the moving process by matching the anti-separation piece 15 and the stop piece 14, so that the stability of the structure is further improved. The working principles of the air heater and the hot air pipe are specifically disclosed in the Chinese patent with the publication number of CN214842222U, so that the working principles are not repeated herein.
While the present utility model has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the utility model as defined in the following claims.
