Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glue dipping equipment, in particular to an unwinding machine for a glue dipping production line. Background Art
[0002] As an important part of modern industrial production, the dipping production line is mainly used to coat the film material through the dipping equipment to meet the production needs of various products. In the dipping production line, the unwinder is an indispensable component. Its main function is to unwind and supply the film material to ensure the continuous and stable operation of the production line. However, with the expansion of production scale and the improvement of production efficiency, the performance requirements of the unwinder are becoming increasingly stringent.
[0003] Deficiencies of existing technology:
[0004] At present, the existing uncoilers on the market generally adopt a double storage roller structure, that is, one storage roller is used for unwinding, and the other storage roller is used as a spare. When the film material in the storage roller being unwound is about to run out, the positions of the two storage rollers are swapped through the driving mechanism, so that the spare storage roller is moved to the unwinding position to continue unwinding. Although this design has improved the unwinding speed and production efficiency of the uncoiler to a certain extent, the connection between the front and rear film materials has become a problem during the roll changing process. When changing the roll of the existing uncoiler, the staff often needs to manually dock the front and rear end film materials and fix them with external force. This process is not only cumbersome and time-consuming, but also prone to problems such as uneven docking and excessive stretching of the film material, which seriously affects the quality and production efficiency of the product.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example
[0031] See also Figure 1-4As shown, the utility model provides a technical solution of an unwinder for a dipping production line: an unwinder for a dipping production line, comprising a base 1 and a mounting box 2 mounted on one side of the upper end surface of the base 1, a driving disc 3 mounted on one side of the mounting box 2, a storage roller 4 mounted horizontally and symmetrically on one side of the driving disc 3, when the material on one storage roller 4 is put out, the driving disc 3 is started, and the front and rear storage rollers 4 are swapped by rotating, a connection mechanism 5 is mounted on the wall of the mounting box 2 above the storage roller 4, a clamping mechanism 6 is mounted on the upper end surface of the base 1 at the discharge side of the storage roller 4; the connection mechanism 5 comprises a motor 501, a hollow pressure head 504, a telescopic rod 505 and a connecting hose 507. The motor 501 is mounted on one side of the mounting box 2 through a bracket above the discharge storage roller 4, a screw rod 502 is connected to the output end of the motor 501, and a lifting sleeve 503 is threadedly connected to the screw rod 502. The hollow pressure head 504 is installed at the lower end of the lifting sleeve 503, and a plurality of vent holes 5041 are provided at the lower end of the hollow pressure head 504. The telescopic rod 505 is installed on the wall of the installation box 2 and is located on one side of the lifting sleeve 503. An air pipe 506 is installed at one end of the telescopic rod 505, and the output end of the telescopic rod 505 is slidably sealedly connected to the inner wall of the air pipe 506 through the installation piston. One end of the connecting hose 507 is connected to the connecting port at the lower end of the air pipe 506, and the other end of the connecting hose 507 is connected to the connecting port at the upper end of the hollow pressure head 504. When the dipping production line starts production, the unwinder is started, and the storage roller 4 at the discharge end of the drive disc 3 starts to unwind, and the film material passes through the clamping mechanism 6 and enters the dipping production line. At this time, the staff first manually opens the film material on the rear storage roller 4, and neatly fits the front edge of the film material to the lower end of the hollow pressure head 504, and then starts the telescopic rod 505, which drives the piston to contract, forming a negative pressure in the hollow pressure head 504, so that the front edge of the film material is stably adsorbed to the lower end of the hollow pressure head 504. When the internal controller of the uncoiler detects that the storage roller 4 at the discharge end of the drive disk 3 is about to be unwound, the staff manually glues the front edge of the film material, and then starts the motor 501. The motor 501 drives the hollow pressure head 504 and the glue-coated part of the rear film material to move toward the front storage roller 4 through the lifting sleeve 503. When it is about to contact the unwinding storage roller 4, the unwinding is stopped, and the motor 501 continues to operate until the glue-coated part of the rear film material is bonded to the front film material and a certain pressure is applied. At this time, the telescopic rod 505 drives the piston to reset, and the hollow pressure head 504 is positively pressurized. After the front and rear films are pressed together for one second, the motor 501 is started again to reverse, and the motor 501 drives the hollow pressure head 504 to reset, and the connection of the front and rear film materials is completed. The connection part of the front and rear film materials can be cut off later according to actual needs. Then, during the unwinding process of the storage roller 4, the drive disk 3 is rotated to move the unwinding storage roller 4 to the discharge end, and the empty storage roller 4 at the rear end can be replaced to prepare for the next film material connection.Through the connection mechanism 5, it is possible to actively and quickly connect the front and rear film materials when the uncoiler storage roller 4 is about to finish unwinding. The whole process is simple to operate and takes a short time. When unwinding, the staff has enough time to align the rear end film material with the hollow pressure head 504 and apply glue. The connection accuracy is higher than that of manual connection, which improves the overall production efficiency.
[0032] The clamping mechanism 6 includes a support seat 601, an upper hollow roller 604 and an electromagnet 606. The support seat 601 is fixedly mounted on the upper end surface of the base 1 and located on one side of the installation box 2. A slide groove 602 is provided on the side adjacent to the support seat 601 and the installation box 2, and a slider 603 is slidably connected in the slide groove 602. The upper hollow roller 604 is rotatably connected between the support seat 601 and the installation box 2, and a lower hollow roller 605 is rotatably connected between the slider 603. The lower hollow roller 605 is aligned with the upper hollow roller 604 and installed up and down. The electromagnet 606 is respectively installed inside the support seat 601 and the installation box 2 and is located below the slider 603. A permanent magnet 607 is also installed at the lower end of the slider 603. When the motor 501 is started and the front and rear film materials are ready to be connected, the electromagnet 606 is energized to generate a repulsive force on the permanent magnet 607, so that the slider 603 moves up along the slide groove 602 until it drives the lower hollow roller 605 to move up and together with the upper hollow roller 604, it generates a certain clamping force on the film material passing through the inside. After the connection part of the front and rear film materials passes through the upper hollow roller 604 and the lower hollow roller 605, the electromagnet 606 is turned off, and the lower hollow roller 605 can move down and reset under the action of gravity. Through the clamping mechanism 6, a secondary clamping operation is achieved for the part where the film material is connected, so as to avoid insufficient downward pressure of the hollow pressure head 504, loose bonding of the film material, and separation of the connection part of the front and rear film materials during the later dipping, thereby further improving the overall production efficiency of the dipping production line.
[0033] The lower end surface of the hollow pressure head 504 is provided with an arc surface matching the wall of the storage roller 4. The arc surface of the hollow pressure head 504 can make the front and rear film materials more evenly stressed during pressing, and the connection more stable.
[0034] The connecting hose 507 is a retractable spring hose. When the front and rear film materials do not need to be connected, the connecting hose 507 is retracted upward and will not affect the normal unwinding operation of the equipment.
[0035] The number of upper hollow rollers 604 and lower hollow rollers 605 is three respectively. An appropriate number of roller sets can both ensure the lamination quality and avoid increasing the production cost.
[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
