Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a glue coating device. Background Art

[0002] The gluing device is mainly used for the surface coating process production of film, paper, tape, etc. It is to coat the rolled substrate with a layer of glue, coating or ink with specific functions, and then rewind it after drying. Existing coating machines all use gluing devices to apply glue to the coating surface. Most of the existing coating devices can only apply glue to one side of the coating surface, while the double-sided gluing coating device has a complex structure and is inconvenient to operate. In addition, the existing device is prone to glue leakage during gluing, and the glue distribution is uneven due to glue leakage, and the roller is not easy to disassemble, which greatly reduces the gluing efficiency.

[0003] For example, Chinese patent 201922190230.X discloses a tape oil glue gluing device, including a body fixed to the ground, a glue storage mechanism connected to the body, and a glue dipping mechanism slidably arranged on the body, the glue dipping mechanism is located above the glue storage mechanism and can extend into the glue storage mechanism, the glue storage mechanism includes a glue storage box rotatably connected to the body and open at the upper end, the inner wall of the body is provided with a control component for controlling the rotation of the glue storage box, the outer wall of the glue storage box is provided with an overflow trough, and the bottom of the glue storage box is connected to a discharge pipe. However, the gluing device performs the gluing operation by external gluing of the glue coating roller. In order to ensure the coating quality, the contact position between the glue storage box and the glue coating roller is usually open. As a result, the glue stored in the glue storage box is exposed to the air for a long time, and the glue will be contaminated or oxidized, which greatly reduces the quality of the glue after coating, thereby affecting the glue coating quality.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0023] According to an embodiment of the utility model, a glue coating device is provided.

[0024] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 5As shown, the gluing device according to the embodiment of the utility model includes a base 1, and the top of the base 1 is sequentially provided with a reel 2, a support frame 3, two support frames 4, a drying fan 5 and a winding roller 6. In specific application, one end of the winding roller 6 is provided with a servo motor for providing power; the inside of the support frame 3 is sequentially provided with a gluing roller assembly 7 and an auxiliary roller 8 located below the gluing roller assembly 7. In specific application, both ends of the gluing roller assembly 7 are rotatably connected to the support frame 3 through bearings, a collecting trough 9 is provided below the auxiliary roller 8 and at the top of the base 1, and a motor 10 matched with the gluing roller assembly 7 is provided on one side of the support frame 3; an adjusting mechanism 11 is provided on the inner side of the middle part of the support frame 4, and the two adjusting mechanisms 11 are connected through two groups of compacting rollers 12.

[0025] With the aid of the above technical solution, by providing a glue coating roller assembly 7 and an adjusting mechanism 11, not only can the glue coating roller assembly 7 be used to prevent the glue from being contaminated or oxidized due to long-term exposure to the air, but the adjusting mechanism 11 can also be used to adjust the distance between the two sets of compacting rollers 12, so as to better realize the gluing operation of lens tapes of different sizes and better meet the needs of enterprises for lens tape production.

[0026] In one embodiment, the glue coating roller assembly 7 includes a roller 701 disposed inside the support frame 3. When used in a specific application, the end of the roller 701 away from the glue feeding pipe 702 is connected to the output end of the motor 10 through a gear assembly, that is, the output end of the motor 10 is sleeved with a driving gear, and the rotating shaft at one end of the glue feeding pipe 702 is sleeved with a driven gear that matches the driving gear. The roller 701 is provided with a glue feeding pipe 702 at one end. When used in a specific application, the glue feeding pipe 702 is connected to an external glue supply pipe through a rotary joint. A glue feeding cavity 703 connected to the glue feeding pipe 702 is provided at one end of the roller 701. A plurality of glue outlet channels 704 are arranged around the glue feeding cavity 703 away from the end of the glue feeding pipe 702. A plurality of glue outlet channels 705 are evenly arranged on the glue outlet channels 704. The glue feeding pipe 702 is located at the end of the roller 701 away from the motor 10. One end of the glue outlet pipe 705 away from the glue outlet channel 704 penetrates the roller 701 and fits with the outer circumferential arc surface of the roller 701. By providing the glue coating roller assembly 7, the glue flows out from the inside of the roller 701 under the action of the glue outlet channel 704 and the glue outlet pipe 705, thereby effectively preventing the glue from being contaminated or oxidized due to long-term exposure to the air, thereby effectively ensuring the coating quality of the glue.

[0027] In one embodiment, the adjustment mechanism 11 includes a fixed plate 1101 arranged inside the support frame 24, two sets of guide rails 1102 are vertically interspersed on the fixed plate 1101, a movable plate 1103 is arranged inside the fixed plate 1101, connecting rods 1104 are arranged at both ends of the movable plate 1103, and one end of the connecting rod 1104 away from the movable plate 1103 is connected to the fixed seat 1105. In specific application, in order to facilitate the rotation of the compaction roller 12, the fixed seat 1105 is movably connected to the compaction roller 12 through a rotating shaft, and a cylinder 1106 connected to the fixed plate 1101 is arranged on one side of the fixed seat 1105. In specific application, the power source of the cylinder 1106 is realized by an external air pump. The side of the fixed seat 1105 away from the cylinder 1106 is rotatably connected to the compaction roller 12. The fixed seat 1105 is sleeved on the two sets of guide rails 1102. By providing the adjustment mechanism 11, the cylinder 1106 can move the fixed seat 1105 in opposite or opposite directions, so as to adjust the distance between the two sets of compacting rollers 12, thereby better realizing the gluing operation of lens tapes of different sizes, and better meeting the needs of enterprises for lens tape production.

[0028] The working principle of the adjustment mechanism is as follows: by driving the extension of the cylinder 1106, the output end of the cylinder 1106 drives the fixed plate 1101 to move upward, and because the fixed plate 1101 is fixedly installed on the guide rail 1102, the fixed plate 1101 cannot move upward, so the extension of the cylinder 1106 can only drive the fixed seat 1105 at the bottom of the cylinder 1106 to move downward, and in the process of the fixed seat 1105 at the bottom moving downward, it will drive the connecting rod 1104 connected thereto to move downward, and because The length of the connecting rod 1104 is fixed, so when the bottom connecting rod 1104 moves downward, it will drive the left side of the movable plate 1103 to rotate counterclockwise around its center, thereby causing the right side of the movable plate 1103 to rotate counterclockwise, and then cooperate with the top connecting rod 1104 to drive the top fixed seat 1105 to move upward, so that the two groups of fixed seats 1105 move in opposite directions. Conversely, when the cylinder contracts, it will drive the two groups of fixed seats 1105 to move in opposite directions, thereby completing the adjustment of the distance between the fixed seats 1105.

[0029] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0030] In actual application, when the lens tape needs to be coated with glue, the worker first inserts the lens tape on the unwinding roller 2, then passes one end of the lens tape through the auxiliary roller 8 and the compacting roller 12 in sequence, and winds it around the winding roller 6, then connects the glue inlet pipe 702 with the glue supply pipe through a rotary joint, and then controls the glue supply pipe, the motor 10 and the winding roller 6 to start working at the same time, thereby providing power for the winding of the lens tape under the action of the winding roller 6, driving the glue coating roller assembly 7 to rotate under the action of the motor 10, and providing a glue source for the glue coating roller assembly 7 under the action of the glue supply pipe, so that the glue can flow out from the glue outlet pipe 705 on the surface of the roller 701, and the gluing operation of the lens tape is realized through the rotation of the roller 701, completing the production of the lens tape.

[0031] In summary, with the aid of the above technical solution of the utility model, by providing a glue coating roller assembly 7 and an adjusting mechanism 11, not only can the glue coating roller assembly 7 be used to prevent the glue from being contaminated or oxidized due to long-term exposure to the air, but the adjusting mechanism 11 can also be used to adjust the distance between the two sets of compacting rollers 12, thereby better realizing the gluing operation of lens tapes of different sizes and better meeting the needs of enterprises for lens tape production.

[0032] In addition, by providing a glue coating roller assembly 7, the glue flows out from the inside of the roller 701 under the action of the glue outlet channel 704 and the glue outlet pipe 705, thereby effectively preventing the glue from being contaminated or oxidized due to long-term exposure to the air, thereby providing effective protection for the coating quality of the glue.

[0033] In addition, by providing an adjustment mechanism 11, the cylinder 1106 can move the fixed seat 1105 in opposite or reverse directions, thereby adjusting the distance between the two sets of compacting rollers 12, and further better realizing the gluing operation of lens tapes of different sizes, better meeting the needs of enterprises for lens tape production.
