Description

Technical Field

[0001] The utility model belongs to the technical field of foam production, in particular to a glue coating machine for foam production. Background Art

[0002] Glue coating machine is also called coating machine, glue scraper, automatic glue sprayer, etc. It is a mechanical equipment mainly used to apply liquid glue on the surface of textiles, paper boxes or leather. There are many types of existing glue coating machines, such as drum glue coating machine, double-acting glue coating machine, double-station lifting glue coating machine, etc. The coating machine sprays liquids such as glue or paint onto the required products through air pressure. The equipment adopts three-axis linkage and automatic operation, and is equipped with computer programming to control the path spraying. The spraying thickness and time can be set, which is simple and easy to operate.

[0003] However, there are some problems with the prior art: in the production process of foam tape, in order to fill the gap between the foam and other materials, it is necessary to apply glue on the foam to improve the sealing effect. The existing glue coating machine usually adopts a glue coating roller to directly adhere the glue and apply it on the foam surface. However, this easily leads to uneven glue on the surface of the glue coating roller and poor glue coating uniformity, which affects the subsequent curing effect and cannot guarantee the molding quality of the foam tape. Therefore, we propose a glue coating machine for foam production. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a glue coating machine for foam production, which has the advantage of uniformly coating the glue on the foam, and solves the problem that the glue coating machine usually uses a glue coating roller to directly adhere the glue and apply it on the foam surface, but this easily leads to uneven gluing on the surface of the glue coating roller and poor gluing uniformity, which affects the subsequent curing effect and cannot guarantee the molding quality of the foam tape.

[0005] The utility model is implemented as follows: a gluing machine for foam production, comprising:

[0006] A frame, a placing box is fixedly installed at the bottom of the inner wall of the frame, an active roller is rotatably installed inside the frame, the left end of the active roller penetrates the left side of the frame and is fixedly installed with a motor, the output end of the motor is fixedly installed with the right side of the frame, a transmission roller is rotatably installed inside the frame, blocks are rotatably installed at both ends of the transmission roller, a first screw is rotatably installed on the top of the block through a bearing, the top of the first screw penetrates the top of the frame and is threadedly installed with the frame;

[0007] A scraping assembly is fixedly mounted on the top of the placement box and is used to evenly scrape the glue on the surface of the active roller.

[0008] The scraping assembly includes two groups of mounting blocks, the bottom of the mounting blocks and the top of the placement box are fixedly mounted, a connecting rod is slidably mounted inside the mounting blocks, a scraper is fixedly mounted on the front side of the active roller, the bottom of the scraper is fixedly mounted on the top of the connecting rod, and the back of the scraper is in contact with the surface of the active roller.

DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, the embodiment of the utility model provides a glue coating machine for foam production, comprising:

[0026] A frame 1, a placing box 2 is fixedly installed at the bottom of the inner wall of the frame 1, an active roller 3 is rotatably installed inside the frame 1, the left end of the active roller 3 penetrates to the left side of the frame 1 and is fixedly installed with a motor 4, the output end of the motor 4 is fixedly installed with the right side of the frame 1, a transmission roller 5 is rotatably installed inside the frame 1, blocks 6 are rotatably installed at both ends of the transmission roller 5, a first screw 7 is rotatably installed on the top of the block 6 through a bearing, the top of the first screw 7 penetrates to the top of the frame 1 and is threadedly installed with the frame 1;

[0027] The scraping assembly 8 is fixedly mounted on the top of the placement box 2 , and is used for evenly scraping the glue on the surface of the active roller 3 .

[0028] First, pour the glue into the placement box 2, place the foam on the surface of the active roller 3, and then rotate the first screw 7. The rotation of the first screw 7 drives the block 6 to move to the bottom. The movement of the block 6 to the bottom drives the transmission roller 5 to move to the bottom. The transmission roller 5 moves to the bottom to make it contact with the top of the foam. Next, start the motor 4. The output shaft of the motor 4 drives the active roller 3 to rotate. The active roller 3 rotates to roll the glue inside the placement box 2. The rotation of the active roller 3 allows the foam on its surface to be coated with glue.

[0029] When the active roller 3 is adhered to a lot of glue inside the placement box 2, the scraping component 8 is used to scrape off the glue rolled on the surface of the active roller 3 to prevent excessive glue on the surface of the active roller 3, which will cause excessive glue when the active roller 3 is applied to the foam, causing the glue on the foam to spill, thereby causing glue waste;

[0030] Then when the foam is coated with glue, the side of the foam that is not coated with glue will be in contact with the ground. Then the side of the foam coated with glue will be protected by a protective film to prevent dust from falling on the glue coated on the foam. Finally, the glued foam is placed in a dry and well-ventilated place to prevent the glue surface from becoming damp and ineffective. Then, the storage environment temperature must be kept moderate to avoid high or low temperature affecting the performance of the glue. Finally, do not press or squeeze the glued foam to avoid affecting the viscosity of the glue and the shape of the foam.

[0031] The scraping assembly 8 includes two sets of mounting blocks 81, the bottom of the mounting block 81 is fixedly mounted on the top of the placement box 2, a connecting rod 82 is slidably mounted inside the mounting block 81, a scraper 83 is fixedly mounted on the front side of the active roller 3, the bottom of the scraper 83 is fixedly mounted on the top of the connecting rod 82, and the back of the scraper 83 is in contact with the surface of the active roller 3.

[0032] Through the cooperation between the mounting block 81, the connecting rod 82 and the scraper 83, the scraper 83 and the connecting rod 82 will move toward the bottom due to their own gravity. The connecting rod 82 will move toward the bottom and enter the interior of the mounting block 81. The scraper 83 will contact the surface of the active roller 3 toward the bottom, so that the glue adhering to the active roller 3 can be scraped off, preventing too much glue from being applied to the foam, thereby wasting glue and causing excessive glue to overflow.

[0033] A tension spring 84 is fixedly installed inside the mounting block 81 , and the top of the tension spring 84 and the bottom of the connecting rod 82 are fixedly installed.

[0034] By setting the tension spring 84, the connecting rod 82 can always bear the tension of the tension spring 84, which will make the scraper 83 and the active roller 3 more stable when in contact, and also prevent the scraper 83 from being affected by the surface of the active roller 3 and temporarily detaching from the active roller 3, thereby causing the scraper 83 to be unable to effectively scrape off the glue evenly.

[0035] A transmission rod 9 is provided on the left side of the frame 1, and the right end of the transmission rod 9 passes through the interior of the frame 1. A first pulley 10 is fixedly installed on the left side of the surface of the transmission roller 5 and the active roller 3, and a second pulley 11 is fixedly installed on the surface of the transmission rod 9. The first pulley 10 and the second pulley 11 are installed through belt drive.

[0036] Through the cooperation between the transmission rod 9, the first pulley 10 and the second pulley 11, when the motor 4 is started, the active roller 3 and one group of the first pulleys 10 can be driven to rotate. The rotation of the first pulley 10 drives the second pulley 11 to rotate through the belt, so that the active roller 3 and the transmission roller 5 will rotate inward at the same time, so that the glue-coated foam can move faster and the gluing efficiency of the foam can be improved.

[0037] A circular ring 12 is provided on the left side of the frame 1, the interior of the circular ring 12 is in contact with the surface of the transmission rod 9, a second screw rod 13 is rotatably installed on the front side of the circular ring 12, a rectangular block 14 is fixedly installed on the left side of the frame 1, and the front end of the second screw rod 13 penetrates to the front side of the rectangular block 14 and is threadedly installed with the rectangular block 14.

[0038] Through the mutual cooperation of the circular ring 12, the second screw 13 and the rectangular block 14, when the transmission roller 5 moves to the bottom, the belt will gradually disengage from the first pulley 10. At this time, the second screw 13 is pulled, and the second screw 13 rotates to pull the circular ring 12 to the right, and the transmission rod 9 rotates inside the circular ring 12. Then, the second screw 13 will drive the circular ring 12, the transmission rod 9 and the second pulley 11 to move to the right. The movement of the second pulley 11 can tighten the belt that is gradually disengaged from the first pulley 10, so that the active roller 3, the transmission roller 5 and the transmission rod 9 can continue to work.

[0039] A fixing rod 15 is fixedly installed inside the frame 1 . The fixing rod 15 is located in front of the driving roller 5 . The fixing rod 15 is used to limit the foam.

[0040] By setting the fixing rod 15, the foam to be coated with glue can be placed on the top of the fixing rod 15, and then the foam is put in through the top of the active roller 3. The fixing rod 15 can limit the glue-coated foam to prevent the foam from deviating when rolling on the surface of the active roller 3.

[0041] A handle 16 is fixedly mounted on the top of the first screw rod 7 and the front end of the second screw rod 13 .

[0042] By providing the handle 16 , the contact area between the first screw 7 and the second screw 13 can be increased, thereby improving the working efficiency of the first screw 7 and the second screw 13 .

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
