Description

Technical Field

[0001] The utility model relates to the technical field of glue coating machines, in particular to a double-sided glue coating device for a reverse-adhesive waterproof board. Background Art

[0002] When the glue coating machine is in use, the glue material needs to be heated to prevent it from solidifying. Most of the glue coating machines in the prior art continue to heat the glue material in the glue barrel during use. However, during use, the two anti-failure methods of heating and stirring are often used in combination. However, the material flow between the heating part and the stirring part is less, which changes the properties of the glue in the heating part, thereby making the properties of the glue in the stirring part different from those of the glue in the heating part, affecting the product quality of the coated product. Utility Model Content

[0026] The working principle and beneficial effects of the utility model are:

[0027] The utility model is designed with a glue-spreading shaft and a nozzle for glue-spreading, and a glue barrel for stirring the glue.

Compared with the existing glue barrel, the possibility of glue failure can be effectively reduced, the product performance of the anti-sticking waterproof board after the glue is sprayed is improved, and the defective rate of the anti-sticking waterproof board is reduced.

[0036] Reference Figure 1~Figure 2 , is an embodiment of the utility model, and proposes

[0037] Double-sided gluing device for reverse-adhesive waterproof board, including

[0038] Rack 1,

[0039] The gluing shaft 2 is rotatably arranged on the frame 1.

[0040] Nozzle 3, which is arranged on the frame 1, faces the glue coating shaft 2, and has a glue inlet 301.

[0041] The glue barrel 5 has a glue outlet 501, and the glue outlet 501 is connected to the glue inlet 301.

[0042] The scraper 4 is rotatably arranged in the rubber barrel 5 and abuts against the wall of the rubber barrel 5. The scraper 4 is arranged at an obtuse angle to the radial direction of the rubber barrel 5. The scraper 4 has a scraping surface, which faces the axis of the rubber barrel 5.

[0043] The stirring member 6 is rotatably disposed in the rubber barrel 5 , and the stirring member 6 is coaxial with a rotating shaft 7 of the scraper 4 , and the stirring member 6 rotates in opposite directions to the scraper 4 .

[0044] In this embodiment, a glue coating shaft 2 and a nozzle 3 are designed for coating glue, and a glue barrel 5 is designed for stirring the glue. When the stirring member 6 stirs the glue, the scraper 4 rotates synchronously to scrape off the glue adhered to the wall of the stirring barrel to avoid the glue that has been in the heating zone for a long time from being denatured and failing. During use, the glue barrel 5 of the prior art also adopts the form of a scraper 4 to prevent the glue from failing, but the scraper 4 of the prior art only scrapes off the glue and cannot guide it to the stirring position of the stirring member 6. The scraper 4 set at an obtuse angle to the radial direction of the glue barrel 5 can guide the material to the stirring member 6 area during the rotation process, and the scraper 4 rotates along the inclination direction of the scraper 4. This rotation method can shovel the glue toward the stirring member 6. Under the accumulation of the glue, the glue can be pushed onto the stirring member 6. The stirring member 6 and the scraper 4 set to rotate in opposite directions can more conveniently send the glue from the scraper 4 to the stirring member 6 under the interaction of the glue itself. Compared with the glue barrel 5 of the prior art, the possibility of failure of the glue can be effectively reduced, the product performance of the anti-sticking waterproof board after the glue is sprayed is improved, and the defective rate of the anti-sticking waterproof board is reduced.

[0045] Furthermore, the scraper 4 has an avoidance gap 401 , and the stirring member 6 passes through the avoidance gap 401 during the rotation process.

[0046] In this embodiment, the scraper 4 has an avoidance gap 401, and the stirring member 6 passes through the avoidance gap 401 during rotation. When the stirring member 6 passes through the avoidance gap 401, the fluidity and viscosity of the rubber can bring the rubber stuck on the scraper 4 to the side of the stirring member 6, thereby effectively reducing the amount of rubber adhesion on the scraper 4 and further reducing the possibility of rubber failure.

[0047] Furthermore, it also includes

[0048] The rotating shaft 7 is rotatably arranged in the rubber barrel 5, and the scraper 4 is arranged on the rotating shaft 7. The rotating shaft 7 has a first inner gear ring 701.

[0049] The sleeve 8 is rotatably arranged on the rotating shaft 7, the sleeve 8 has a second inner gear ring 801, and the stirring member 6 is arranged on the sleeve 8.

[0050] The first idle gear 9 is disposed on the rubber barrel 5 and is located inside the rubber barrel 5, and is meshed with the first inner gear ring 701.

[0051] The second idle gear 10 is disposed on the rubber barrel 5 and located inside the rubber barrel 5 , and is meshed with the second inner gear ring 801 and the first idle gear 9 .

[0052] In this embodiment, a rotating shaft 7 is designed. When the rotating shaft 7 rotates, the scraper 4 is driven to rotate. The rotating shaft 7 has a first inner gear ring 701. The first inner gear ring 701 drives the first idle gear 9 to rotate. When the first idle gear 9 rotates, it drives the second idle gear 10 to rotate. The second idle gear 10 drives the sleeve 8 to rotate through the inner gear ring. The synchronous reverse rotation of the rotating shaft 7 and the sleeve 8 is achieved through the gear set. The structure is simple and not easy to be damaged.

[0053] Furthermore, the rubber barrel 5 has a transmission cavity 502 , and the first idle gear 9 , the second idle gear 10 , the first inner gear ring 701 and the second inner gear ring 801 are all arranged in the transmission cavity 502 .

[0054] In this embodiment, the rubber barrel 5 has a transmission chamber 502, which is a sealed chamber. The first idle gear 9, the second idle gear 10, the first inner gear ring 701 and the second inner gear ring 801 are all arranged in the transmission chamber 502, which can effectively avoid gear damage caused by rubber falling onto the teeth of the first idle gear 9, the second idle gear 10, the first inner gear ring 701 and the second inner gear ring 801, thereby extending the service life of the equipment.

[0055] Furthermore, the nozzle 3 has a closing portion 302 , and the nozzle 3 has a plurality of spray holes 303 . The spray holes 303 are located on the side of the nozzle 3 , and the spray holes 303 face the glue coating axis 2 .

[0056] In this embodiment, the nozzle 3 has a closing portion 302. When the rubber passes through the closing portion 302, a certain pressurization effect can be achieved due to the change in the diameter of the passage. When the rubber is sprayed from the spray hole 303 to the anti-sticky waterproof board, the adhesion in the air is reduced, the spraying effect is more uniform, and the product quality is improved.

[0057] Furthermore, the stirring element 6 has a stirring portion 602 , and the stirring portions 602 are multiple and arranged in a spiral manner.

[0058] In this embodiment, there are multiple stirring parts 602 arranged in a spiral pattern. The stirring parts 602 are used to pass through the avoidance gap 401. The multiple stirring parts 602 can effectively reduce the accumulation of rubber on the scraper 4, thereby reducing the possibility of rubber denaturation.

[0059] Furthermore, it also includes

[0060] The sliding member 11 is slidably disposed on the stirring portion 602 . During the rotation of the stirring member 6 , the sliding member 11 abuts against or cancels the abutment with the scraper 4 .

[0061] In the present embodiment, in order to ensure that the rubber material can be discharged from the scraper 4 smoothly, a sliding member 11 is also designed. The sliding member 11 is slidably arranged on the stirring portion 602. When the sliding member 11 is not in contact with the scraper 4, the sliding member 11 moves from the sleeve 8 to the wall of the rubber barrel 5 along the radial direction of the rubber barrel 5 when the stirring portion 602 rotates. When the sliding member 11 is in contact with the scraper 4, the sliding member 11 moves from the wall of the rubber barrel 5 to the sleeve 8 along the radial direction of the rubber barrel 5 under the action of the scraper 4. The rubber material can be scraped from the scraper 4 to the stirring portion 602 through the contact and relative sliding of the sliding member 11 and the scraper 4, which can effectively reduce the possibility of the rubber material sticking to the scraper 4, reduce the generation of failed rubber, and improve product quality.

[0062] Furthermore, the sliding member 11 has a flexible abutting portion 1101 , and the flexible abutting portion 1101 is used to abut against the scraper 4 .

[0063] In this embodiment, in order to prevent the sliding member 11 from being damaged by collision when it abuts against the scraper 4, a flexible abutting portion 1101 is provided on the sliding member 11 to reduce the damage rate of the equipment.

[0064] Furthermore, the scraper 4 has a supporting portion 402 , which is fan-shaped and abuts against the wall of the rubber barrel 5 .

[0065] In this embodiment, since the scraper 4 collides and abuts against the sliding member 11 , in order to reduce the failure rate of the equipment, a support portion 402 is designed to extend the service life of the scraper 4 .

[0066] Furthermore, the scraper 4 is made of hard metal.

[0067] In this embodiment, in order to reduce the damage rate of the scraper 4, the scraper 4 is made of hard metal.

[0068] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
