Description

Technical Field

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

[0002] A glue coating machine, also known as a coating machine, scraper, or automatic glue sprayer, is a mechanical device primarily used to apply liquid glue to textiles, cartons, or leather surfaces. Existing glue coating machines come in a variety of styles, including drum glue coating machines, double-action glue coating machines, and dual-station lift glue coating machines. In existing double-roller glue coating systems, the lower roller is immersed in a glue tank, while the glue from the upper roller is transferred to the lower roller. This configuration simplifies the glue coating machine's structure and facilitates maintenance and operation. However, existing glue coating machines still rely on manual control of glue flow. Once glue adheres to the baffle and the glue outlet, the baffle cannot be removed, hindering subsequent work and affecting work efficiency.

[0003] For example, an existing patent (Announcement No.: CN216173651U) discloses a film gluing device with automatic glue adjustment and supply, comprising a support frame, a fixed plate fixedly connected to the side of the upper surface of the support frame, a mounting groove formed on the side of the fixed plate, a movable plate installed inside the mounting groove, and a gluing mechanism provided on the upper surface of the movable plate. This film gluing device with automatic glue adjustment and supply, through the arrangement of a baffle, a glue outlet hole, a threaded rod, a threaded hole, and a hole, when the baffle is fully inserted into the through hole, the baffle blocks the glue outlet hole and the glue does not flow out. During operation, the threaded rod is rotated counterclockwise. Due to the existence of the threaded hole, the baffle moves outward along the threaded rod. At this time, the hole slowly overlaps with the glue outlet hole, and the glue in the glue trough flows out of the glue outlet hole to provide glue to the upper gluing roller.

[0004] However, the above-mentioned film gluing device with automatic glue adjustment and supply still has some shortcomings in actual use: the glue for the upper and lower glue coating rollers of the film gluing device is provided separately, and there is no need to rotate one circle to replenish the glue, which improves work efficiency. However, the baffle and the lower glue port will stick together due to the residual glue, resulting in the baffle being unable to move with the loosening of the bolts when subsequent work is required, and thus the lower glue port is always blocked, affecting work efficiency.

[0005] Therefore, we designed a glue supply device for a film coating machine to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a glue supply device for a film coating machine to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the utility model provides a glue supply device for a thin film coating machine, comprising a bottom cover, a rotating shaft rotatably installed inside the bottom cover, cranks fixedly installed at both ends of the rotating shaft, a rocker rotatably installed on one side of the crank, a second pin shaft inserted at one end of the rocker, a connecting rod rotatably installed on the second pin shaft, a baffle fixedly installed at the other end of the connecting rod, a first motor provided at one end of the rotating shaft, one end of the rotating shaft is transmission-connected to the drive shaft of the first motor, and the baffle is driven to slide in and out of the slide groove by the forward and reverse rotation of the motor;

[0008] A glue tank is fixedly installed on the top of the bottom cover, and a stirring rod is rotatably connected to the inside of the glue tank. An eccentric wheel is provided at one end of the stirring rod. The center of the eccentric wheel is connected to the driving shaft of the second motor. The motor controls the eccentric wheel to drive the stirring rod to stir up and down to prevent the glue from solidifying.

[0009] A side shell is provided on one side of the gluing tank, and a plurality of fixing rods are fixedly installed inside the side shell. A heating wire is wound around the surface of each fixing rod.

[0010] Furthermore, a first pin is inserted into the other end of the rocker, and the rotating shaft is rotatably mounted on the rocker via the first pin, thereby ensuring that both ends of the rocker can rotate and the baffle can reciprocate linearly.

[0011] Furthermore, a lower glue plate is provided at the bottom of the upper glue groove, a sliding groove is provided inside the lower glue plate, and the baffle is slidably connected to the sliding groove.

[0012] Furthermore, connecting seats are provided at both ends of the gluing groove, and a frame is installed at the bottom of the connecting seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By starting the first motor, the first motor drives the rotating shaft to rotate together with the crank. At this time, one end of the rocker follows the movement of the crank, and at the same time, one end of the rocker rotates around the first pin shaft, and the other end of the rocker rotates around the connecting rod. Since the length of the rocker is certain, the rocker rotates at both ends while pushing the connecting rod and the baffle to move forward at the same time. The baffle moves along the slide until the baffle completely blocks the slide. At this time, the glue no longer flows out and the gluing work is suspended. To resume the gluing work, the first motor is reversed, and the crank, rocker and connecting rod drive the baffle to slide out of the slide, and the glue continues to flow out through the through hole in the lower glue plate.

[0015] 2. At this time, the second motor is started, and the second motor drives the eccentric wheel to rotate. The stirring rod starts to rotate up and down at the same time to stir the glue, which prevents the static glue from solidifying and causing inconvenience to subsequent work. By setting a fixed rod and a heating wire, the lower glue plate and the upper glue tank are heated, which further prevents the glue from solidifying, avoids the impact on subsequent work, and improves work efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: a glue supply device for a thin film coating machine, comprising a bottom cover 1, a rotating shaft 2 is rotatably installed inside the bottom cover 1, a crank 3 is fixedly installed at both ends of the rotating shaft 2, a rocker 4 is rotatably installed on one side of the crank 3, a second pin 6 is inserted at one end of the rocker 4, a connecting rod 7 is rotatably installed on the second pin 6, a baffle 8 is fixedly installed at the other end of the connecting rod 7, a first motor is provided at one end of the rotating shaft 2, one end of the rotating shaft 2 is transmission-connected to the drive shaft of the first motor, a first pin 5 is inserted at the other end of the rocker 4, and the rotating shaft 2 is rotatably installed on the rocker 4 through the first pin 5.

[0024] During specific implementation, the first motor is started, which drives the rotating shaft 2 and the crank 3 to rotate together. At this time, one end of the rocker 4 moves along with the crank 3. At the same time, one end of the rocker 4 rotates around the first pin 5, and the other end of the rocker 4 rotates around the connecting rod 7. Since the length of the rocker 4 is fixed, the rocker 4 rotates at both ends while pushing the connecting rod 7 and the baffle 8 forward at the same time. The baffle 8 moves along the chute 10 until the baffle 8 completely blocks the chute 10. At this time, the glue no longer flows out and the gluing process is suspended. To resume the gluing process, the first motor is reversed, and the crank 3, rocker 4, and connecting rod 7 drive the baffle 8 to slide out of the chute 10. The glue continues to flow out through the through-holes in the lower glue plate 16. Through motor control, labor is reduced and the inconvenience caused by starting and stopping the machine is avoided.

[0025] like Figure 1-5 As shown, a gluing groove 9 is fixedly installed on the top of the bottom cover 1, and a stirring rod 11 is rotatably connected inside the gluing groove 9. An eccentric wheel is provided at one end of the stirring rod 11, and the center of the eccentric wheel is connected to the driving shaft of the second motor. A lower glue plate 16 is provided at the bottom of the gluing groove 9, and a slide groove 10 is provided inside the lower glue plate 16. The baffle 8 is slidably connected to the slide groove 10. A side shell 12 is provided on one side of the gluing groove 9, and a plurality of fixed rods 13 are fixedly installed inside the side shell 12. A heating wire 14 is wound around the surface of each fixed rod 13. Connecting seats 15 are provided at both ends of the gluing groove 9, and a frame is installed at the bottom of the connecting seat 15.

[0026] Start the second motor, the second motor drives the eccentric wheel to rotate, and the stirring rod 11 starts to rotate up and down at the same time to stir the glue, preventing the static glue from solidifying and causing inconvenience to subsequent work. By setting the fixing rod 13 and the heating wire 14, the lower glue plate 16 and the upper glue groove 9 are heated, further preventing the glue from solidifying, avoiding the impact on subsequent work, and improving work efficiency.

[0027] Working principle: First, the machine is connected to the power supply. At this time, the glue flows along the pipe into the upper glue groove 9, and then flows along the through-hole in the lower glue plate 16 to the roller to start the gluing process. When the gluing process needs to be suspended, the first motor is started. The first motor drives the rotating shaft 2 and the crank 3 to rotate together. At this time, one end of the rocker 4 follows the movement of the crank 3, and at the same time, one end of the rocker 4 rotates around the first pin 5, and the other end of the rocker 4 rotates around the connecting rod 7. Since the length of the rocker 4 is fixed, the rocker 4 rotates at both ends while pushing the connecting rod 7 and the baffle 8 forward at the same time. The baffle 8 moves along the chute 10 until the baffle 8 completely blocks the chute 10. At this time, the glue stops flowing and the gluing process is suspended. To resume the gluing process, the first motor is reversed, and the crank 3, rocker 4 and connecting rod 7 drive the baffle 8 to slide out of the chute 10, and the glue continues to flow out through the through-hole in the lower glue plate 16. Through motor control, labor is reduced and the inconvenience caused by starting and stopping the machine is avoided.

[0028] When the glue flows into the glue tank 9, if it is left stationary for a long time, the glue will solidify. At this time, the second motor is started, and the second motor drives the eccentric wheel to rotate. The stirring rod 11 starts to rotate up and down at the same time to stir the glue, preventing the stationary glue from solidifying and causing inconvenience to subsequent work.

[0029] Since glue residue is unavoidable at the glue outlet, when the baffle 8 slides into the chute 10, the residual glue solidifies, causing the baffle 8 to adhere to the chute 10. It becomes more difficult to slide the baffle 8 out of the chute 10, and may even burn out the second motor. By providing the fixing rod 13 and the heating wire 14 to heat the lower glue plate 16 and the upper glue chute 9, the glue is further prevented from solidifying, avoiding the impact on subsequent work and improving work efficiency.

[0030] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
