DETAILED DESCRIPTION

[0017] Next, the specific embodiment of the handball glue removing device will be described in detail. Figures 1-5 Next, the specific embodiment of the handball glue removing device will be described in detail.

[0018] Reference will be made to the accompanying drawings. Figures 1-2The utility model provides a handball glue removing device for cleaning the glue attached on the handball, which comprises a base 2 with a built-in hot air blower 1, the top of the base 2 is provided with a wind groove 3 matching the spherical shape of the handball, the handball to be cleaned is placed in the wind groove, and the hot air generated by the hot air blower 1 blows out from the wind groove and blows on the surface of the handball to soften the glue attached on the surface of the handball for being scraped off.

[0019] A ring 4 is fixedly connected to the base 2, and a compression roller 5 is pivotally connected to the inner side of the ring, the compression roller 5 is located at the upper half of the handball 20 placed in the wind groove and is intended to limit the handball downwardly. When the handball is placed in the wind groove 3, the hot air of the hot air blower blows toward the handball, and the force generated by the airflow blows up the handball and presses the handball against the compression roller 5, there is a gap between the handball and the wind groove to form an air duct, at this time, the part of the handball exposed outside the ring serves as the part to be pushed, and the handball in suspension is easy to rotate at any angle, on the one hand, the whole surface of the handball is subjected to the action of the hot air to soften all the glue, and on the other hand, the fixed scraper can perform the glue removing operation on the whole surface.

[0020] Reference is made to the accompanying drawings Figure 4 The inner part of the ring 4 is a cavity, a rotating ring 6 is arranged in the cavity, a positioning column 7 is arranged on the inner wall of the ring, the positioning column 7 circumferentially positions the rotating ring 6, and the rotating ring has a free degree of rotation. An inclined groove 601 is arranged on the rotating ring 6, meanwhile, the compression roller 5 is pivotally connected to a connecting rod 8, the end of the connecting rod penetrates into the inclined groove 601, and a pushing rod 9 extending to the outside of the ring is connected to the outer edge of the rotating ring 6. The pushing rod can drive the rotating ring to rotate, and then the compression roller is extended or retracted in the radial direction (relative to the ring) through the action of the inclined groove and the connecting rod, which is intended to control the distance between the compression rollers and reserve enough space for the handball to be placed or taken out.

[0021] In this embodiment, the positioning column 7 can be a threaded column, the ring is composed of two detachable cover shells, and the assembly of the ring is completed through the cooperation of a fastener such as a screw and the threaded column.

[0022] Reference is made to the accompanying drawings Figure 1 Spring sleeve columns 10 are arranged in the inner cavity of the ring 4 and on the rotating ring 6, and the two spring sleeve columns 10 are connected by a spring 11. The spring force of the spring has a pre-tightening force for rotation, and there is always a tendency to drive the compression roller to extend, and through the spring force, the handball can be stabilized under the action of the hot air in the process of scraping off the glue.

[0023] Reference is made to the accompanying drawings Figure 1 A clamping groove 401 is arranged on the outer wall of the ring 4, the clamping groove is used for the movement of the pushing rod 9, and a clamping position 402 is arranged on the clamping groove. The clamping position is used to maintain the retracted state of the compression roller after the rotating ring rotates and drives the compression roller to retract, that is, when the pushing rod 9 is pushed and falls on the clamping position 402, the retracted state of the compression roller is maintained by overcoming the spring force, and the channel for taking and placing the handball is in an open state.

[0024] After the handball is rotated, the scraper 12 can scrape the softened glue on the surface of the handball, based on the interval between the handball and the air chute, which not only serves as an air duct, but also serves as a space required for adjusting the handball, in the process of scraping the glue, the handball is pressed to rotate at any angle after being separated from the pressure roller, and when the scraper is blocked while moving on the fixed groove of the handball surface, the handball is separated from the scraper by pressing, so as to avoid the handball being scratched.

[0025] Referring to the drawings Figure 3 In this embodiment, the scraper 12 is fixed, specifically, the scraper 12 is connected to a rotating rod 13, and a column rod 14 is fixedly connected to the base 2.

The pivot part 131 is pivotally connected to the top of the column rod 14, that is, the rotating rod can rotate relative to the column rod. The scraper 12 can be controlled to contact or separate from the surface of the handball by controlling the handle part 133.

[0026] The fixed knife part 132 and the column rod 14 are connected by a second spring 15. The second spring 15 forms a pressure of the scraper on the surface of the handball by the elastic force thereof. The second spring continuously and constantly maintains the state that the scraper is tightly pressed on the surface of the handball.

[0027] One end of the second spring 15 is connected to a fixed position of the fixed knife part 132, and the other end is connected to a sliding block 16 slidingly arranged on the column rod 14. For example, the sliding block is sleeved on the outer surface of the column rod. A protruding pin part 17 is arranged on the upper part of the sliding block 16. Correspondingly, a pin hole 18 is arranged on the pivot part 131.

[0028] Referring to the drawings Figure 1 and 5 When it is necessary to maintain the scraper tightly pressed on the handball to perform the glue removing operation, the elastic force of the second spring pulls the sliding block upward. The pin part 17 contacts the surface of the pivot part 131 which is not the pin hole 18. When it is necessary to maintain the state that the scraper is separated from the handball, the handle part 133 is pressed downward to rotate the rotating rod 13. When the pin hole 18 of the rotating pivot part 131 is rotated to be opposite to the pin part 17, the pin part 17 is inserted into the pin hole 18 under the pulling of the elastic force of the second spring, so as to complete the locking of the current separation state of the scraper.

[0029] The sliding block 16 is provided with a pressing rod 19. The pin part 17 is slid out of the pin hole 18 by the downward pressing force acting on the pressing rod 19, so as to complete the unlocking of the separation state of the scraper.

[0030] In the process of scraping the glue, the glue can fall on the base, and the glue attached to the scraper and scraped from the handball can be removed. The scraper can be cleaned only by locking the rotating rod 13, and the scraper can also be replaced.

[0031] Based on the handball glue removing device, the application further provides a handball glue removing method through the handball glue removing device, comprising the following steps.

[0032] Placing the handball, pushing the rotating rod 13 to make it fall on the clamping position 402, the pressure roller 5 retracts, the handle part 133 is pressed to rotate the rotating rod 13, until the pin part 17 is inserted into the pin hole 18, the current scraper disengagement state is locked, the handball is placed at the air chute 3, the rotating rod 13 is pushed to reset, and the pressure roller 5 is extended.

[0033] Preheating, starting the hot air blower 1, the hot air blows up the handball, the handball is pushed to rotate, and the handball is temporarily separated from the pressure roller and rotated at an arbitrary angle while being pushed, so as to soften the adhesive on the surface of the handball;

[0034] Scraping, the pressure rod 19 is pressed down until the pin part 17 is separated from the pin hole 18, the rotating rod 13 is rotated under the elastic force of the second spring 15, the scraper is tightly pressed on the surface of the handball under the elastic force, the handball is pushed to rotate until the scraper completely scrapes the surface of the handball.

[0035] Taking out the handball, pushing the rotating rod 13 to make it fall on the clamping position 402, the pressure roller 5 retracts, the handle part 133 is pressed to rotate the rotating rod 13, until the pin part 17 is inserted into the pin hole 18, the current scraper disengagement state is locked, and the handball is taken out.

[0036] The application has simple overall structure, meets the requirement of miniaturization, is easy to operate, and has high scraping efficiency. After the adhesive is softened by the hot air, the adhesive is scraped by the scraper, and the operator assists in intervening in the damage of the handball caused by the scraper, especially when the scraper passes through the ditch.
