Description

Technical Field

[0001] This utility model belongs to the field of filling machines, and more specifically, it relates to a glue filling machine with an anti-drip structure. Background Technology

[0002] Glue filling machines are automated mechanical devices specifically designed to fill liquid glue into various containers, and are widely used in modern packaging production lines. Currently, during the glue filling process, a conveyor belt typically moves the glue bottle to the bottom of the filling head. The dispensing tube of the filling head then inserts into the bottle and fills the glue according to the set dispensing volume. After filling, the dispensing tube detaches from the bottle, and the conveyor belt moves the filled bottle out of the filling head and then brings in another set of empty bottles for continuous filling. However, in actual filling, a small amount of glue remains in the dispensing tube after filling. The bottom structure of the dispensing tube is relatively exposed, and the glue, affected by the vibration of the mechanical equipment, drips onto the conveyor belt due to gravity. This causes the glue to solidify and stick to the conveyor belt, creating contamination that is difficult to clean. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a glue filling machine with an anti-drip structure, which solves the problem that the glue liquid drips and sticks to the conveyor belt due to the vibration of the mechanical equipment caused by the exposed structure of the glue filling tube in the traditional glue filling machine, thus causing pollution.

[0004] This utility model provides a glue filling machine with an anti-drip structure, including a base; the left and right sides of the base are welded with base plates, a glue storage tank is installed on the upper side of the right base plate, a box cover is installed on the upper side of the glue storage tank, and a control unit is installed on the upper side of the left base plate; it also includes a support plate and a push-pull rod; the lower side of the support plate is welded with a base, the left and right sides of the support plate are welded with guide plates, the upper side of the guide plates is bolted to a stand, the top of the stand is installed with a lifting motor, and a threaded rotating rod is installed on the motor shaft of the lifting motor; the bottom end of the push-pull rod is hinged with a sliding plate, the top end of the push-pull rod is hinged with a lifting slider, the front end of the lifting slider is welded with a connecting plate, the front side of the connecting plate is installed with a glue dispensing head, the glue dispensing head has a glue delivery pipe installed at the glue injection port, and the other end of the glue delivery pipe is installed with a glue storage tank.

[0005] In at least some embodiments, the left and right sides of the lifting slider are provided with cuboid ear plates, the upper side of the cuboid ear plates is provided with a through hole at the center, the center of the lifting slider is provided with a threaded through hole structure that runs vertically through, and the outer side of the threaded rotating rod is threadedly engaged in the threaded through hole of the lifting slider.

[0006] In at least some embodiments, protrusions are welded to the left and right sides of the slide plate, and a rectangular groove with an upper opening is provided on the upper side of the slide plate.

[0011] 1. In this utility model, a threaded transmission mechanism consisting of a threaded rotating rod driven by a lifting motor and a threaded through hole in the lifting slider is operated. This mechanism causes the lifting slider to move back and forth along the long through groove of the guide plate via a push-pull rod hinged to the rear side. After the dispensing head finishes dispensing the glue, the slide plate carrying the dispensing box moves forward to the bottom of the dispensing tube of the dispensing head as the lifting slider rises, blocking and intercepting the dripping glue. This eliminates the exposed structure of the bottom of the dispensing tube of the traditional dispensing head, effectively preventing the glue from dripping directly onto the glue bottle conveyor belt.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1-8 As shown, this utility model provides a glue filling machine with an anti-drip structure, including a base 4; a base plate 1 is welded to both the left and right sides of the base 4, a glue storage tank 9 is installed on the upper side of the right base plate 1, a tank cover 10 is installed on the upper side of the glue storage tank 9, and a control unit 2 is installed on the upper side of the left base plate 1; it also includes a support plate 13 and a push-pull rod 18; the base 4 is welded to the lower side of the support plate 13, and guide plates 12 are welded to both the left and right sides of the support plate 13. A support frame 15 is bolted to the upper side of the 12. A lifting motor 7 is installed at the top of the support frame 15. A threaded rotating rod 16 is installed on the motor shaft of the lifting motor 7. A sliding plate 11 is hinged to the bottom of the push-pull rod 18. A lifting slider 19 is hinged to the top of the push-pull rod 18. A connecting plate 8 is welded to the front end of the lifting slider 19. A glue dispensing head 5 is installed on the front side of the connecting plate 8. A glue delivery pipe 6 is installed at the glue dispensing port of the glue dispensing head 5. A glue storage tank 9 is installed at the other end of the glue delivery pipe 6.

[0023] In this embodiment, the left and right sides of the lifting slider 19 are provided with cuboid ear plates. The upper side of the cuboid ear plate is provided with a through hole at the center. The center of the lifting slider 19 is provided with a threaded through hole structure that runs vertically through the top and bottom. The outer side of the threaded rotating rod 16 is threadedly engaged in the threaded through hole of the lifting slider 19. During the process of the lifting motor 7 driving the threaded rotating rod 16 to rotate, the lifting slider 19 moves up and down. During the process of the lifting slider 19 driving the dispensing head 5 to move up and down through the connecting plate 8, the lifting slider 19 simultaneously drives the sliding plate 11 to move back and forth through the push-pull rod 18. This completes the shielding of the bottom part of the dispensing head 5 by the sliding plate 11 during the rising process of the dispensing head 5, preventing the glue from dripping onto the surface of the conveyor belt.

[0024] In this embodiment, protrusions 20 are welded to both the left and right sides of the slide plate 11. The upper side of the slide plate 11 is provided with a rectangular groove with an upper opening. A dispensing box 14 is placed in the rectangular groove of the slide plate 11. The dispensing box 14 is a groove structure with an upper opening. The dispensing box 14 collects and carries the glue dripping from the dispensing tube at the bottom of the dispensing head 5, so that the accumulated glue can be cleaned separately after the dispensing box 14 is removed from the slide plate 11.

[0025] In this embodiment, there are two sets of guide plates 12, which are symmetrically distributed on the left and right. Each set of guide plates 12 is provided with a long through groove that runs from left to right. The protrusions 20 welded to the left and right sides of the slide plate 11 are respectively embedded in the long through groove of the guide plate 12. The upper and lower sides of the protrusions 20 are respectively attached to the upper and lower groove walls of the long through groove of the guide plate 12. The long through groove of the guide plate 12 supports the slide plate 11 to drive the dispensing box 14 to move horizontally back and forth in a directional manner, so as to prevent the dispensing box 14 placed in the groove of the slide plate 11 from overturning and tipping over, and to ensure that the dispensing box 14 stably supports the dripping glue during the movement.

[0026] In this embodiment, a through groove is provided on the front side of the base 4 near the center of the bottom end. An infrared photoelectric sensor 3 is installed in the through groove of the base 4. The infrared photoelectric sensor 3 reflects infrared light to detect and sense the position of the glue bottle at the bottom of the glue dispensing head 5 in real time, so as to avoid glue dispensing operation when there is no glue bottle at the bottom of the glue dispensing head 5, and to avoid glue being poured onto the surface of the conveyor belt.

[0027] In this embodiment, the left and right sides of the support frame 15 are provided with elongated through grooves. A column 17 is welded to the bottom of the groove inside each set of elongated through grooves. The column 17 is inserted into the ear plate through hole of the lifting slider 19. The two sets of columns 17 support the vertical directional movement of the lifting slider 19, preventing the threaded rotating rod 16 from driving the lifting slider 19 to rotate synchronously. This ensures that the threaded rotating rod 16 stably drives the glue dispensing head 5 installed on the front side connecting plate 8 of the lifting slider 19 to accurately penetrate into the glue bottle for glue dispensing.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When the glue dispensing head 5 is dispensing glue, the external conveyor belt moves the glue bottle to the front of the infrared photoelectric sensor 3. The infrared photoelectric sensor 3 senses the glue bottle in real time and sends a data signal to the controller 2 via a wire. At this time, the controller 2 controls the lifting motor 7 to start via the wire. The lifting motor 7 drives the threaded rotating rod 16 to rotate. Since the threaded rotating rod 16 is threadedly engaged in the threaded through hole of the lifting slider 19, the threaded rotating rod 16 drives the lifting slider 19 to slide vertically downward along the column 17. The lifting slider 19 then drives the glue dispensing head 5 to move downward through the connecting plate 8 welded to the front side. At this time, the lifting slider 19 pushes the push-pull rod 18 hinged to the rear side to flip. The push-pull rod 18 drives the sliding plate 11 hinged at the bottom to move backward along the long through groove of the guide plate 12. The sliding plate 11 drives the dispensing box 14 to move backward away from the bottom position of the glue dispensing head 5. The glue injection tube at the bottom of the glue dispensing head 5 is inserted into the glue bottle. The control machine 2 controls the dispensing head 5 to draw glue from the glue storage tank 9 through the glue delivery pipe 6 via a wire. The dispensing head 5 fills the glue bottle with glue. After filling, the control machine 2 controls the lifting motor 7 to rotate in the opposite direction via a wire. The lifting motor 7 drives the threaded rotating rod 16 to rotate in the opposite direction. The threaded rotating rod 16 drives the lifting slider 19 to slide vertically upward along the column 17. The lifting slider 19 drives the dispensing head 5 to move upward through the connecting plate 8 welded to the front side. At this time, the lifting slider 19 pushes the push-pull rod 18 hinged to the rear side to flip. The push-pull rod 18 drives the slide plate 11 hinged at the bottom to move forward along the long through groove of the guide plate 12. At this time, the height position of the bottom of the dispensing head 5 moves to the upper side of the slide plate 11. The slide plate 11 drives the dripping box 14 to move forward to the position directly below the dispensing head 5. At this time, the dripping box 14 intercepts and blocks the glue dripping from the dispensing pipe opening of the dispensing head 5 to prevent the glue from dripping directly onto the conveyor belt.

[0030] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies; any method that achieves the desired effect can be implemented. The control unit 2, infrared photoelectric sensor 3, dispensing head 5, and lifting motor 7 mentioned above are all common market components. Upon purchase and use, simply connect them according to the instruction manual provided; therefore, further details are omitted here.
