[0001] This utility model relates to the technical field of three-dimensional packaging machine structure, specifically a feeding device for a transparent three-dimensional packaging machine. Background Technology

[0002] Three-dimensional packaging machines, also known as three-dimensional transparent film packaging machines, cigarette packaging machines, transparent film six-sided folding cold packaging machines, and transparent film packaging machines, are intermediate packaging equipment that uses BOPP film or PVC as packaging material to form a three-dimensional six-sided folded and sealed package of the packaged item. They are widely used for three-dimensional skin packaging of cosmetics, pharmaceuticals, food, health products, audio-visual products, stationery, daily necessities, and other products (with the same packaging effect as cigarettes).

[0003] An existing transparent film three-dimensional packaging machine, such as the one with patent publication number CN206013109U, has a feeding mechanism on one side. The feeding mechanism includes a support and a conveyor belt installed on the support. The conveyor belt is connected to a transmission mechanism installed in the support. The conveyor belt includes a horizontal conveyor belt and an arc conveyor belt. The lower end of the arc conveyor belt is connected to the horizontal conveyor belt, and the upper end extends to the worktable of the three-dimensional packaging machine.

[0004] However, this is difficult to achieve in practice for a circular arc conveyor belt body, resulting in poor actual structural performance and low reliability. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a transparent three-dimensional packaging machine feeding device, which has the following beneficial effects:

[0016] According to requirements, the adjusting mechanism acts on the slider to move longitudinally inside the carriage, which in turn drives the constraint shaft frame to move longitudinally.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4A feeding device for a transparent three-dimensional packaging machine includes a base 1, a high shaft frame 2, a low shaft frame 3, a drive motor 4, a reducer 5, a feeding belt 6, rollers 7, belt rollers 8, a slide 9, a slider 10, a constraint shaft frame 11, a constraint shaft 12, and a constraint roller 13. The rear top of the base 1 is connected to the bottom of the low shaft frame 3, and the front top of the base 1 is connected to the bottom of the high shaft frame 2. A set of rollers 7 are rotatably connected to the upper sides of the high shaft frame 2 and the low shaft frame 3, respectively. The outer wall of the rollers 7... The feed belt 6 is movably sleeved on the outside of the two sets of belt rollers 8 and connected to the inner wall of the belt roller 8. The upper right end of the high shaft frame 2 is connected to the inner end of the reducer 5. The output end of the drive motor 4 is connected to the input end of the reducer 5. The output end of the reducer 5 is connected to the side of the roller shaft 7. The top center of the base 1 is connected to the bottom end of the slide 9. The inner side of the slide 9 is longitudinally slidably connected to the outer side of the slider 10. The top of the slider 10 is connected to the middle of the bottom end of the constraint shaft frame 11. The inner upper part of the constraint shaft frame 11 is connected to the inner wall of the belt roller 8. A set of constraint shafts 12 are rotatably installed on the lower side. The outer wall of the constraint shafts 12 is connected to the inner wall of the constraint rollers 13. The two sets of constraint rollers 13 support the inner and upper sides of the feed belt 6, respectively. An adjustment mechanism is provided between the slide 9 and the slider 10. According to the requirements, the slider 10 moves longitudinally inside the slide 9 through the adjustment mechanism, which in turn drives the constraint shaft frame 11 to move longitudinally. After it reaches the position, it stops. The two sets of constraint rollers 13 inside the constraint shaft frame 11 contact the feed belt 6 at this part, forming a corresponding angular arc. When feeding, the paper is inserted through the rear of the top side of the feed belt 6. The drive motor 4 runs and the reducer 5 reduces the speed so that the roller shaft 7 drives the belt roller 8 to rotate under the constraint of the short shaft frame 3. The other set of roller shafts 7 drives the belt roller 8 to rotate under the constraint of the high shaft frame 2. This acts on the feed belt 6, causing the top side of the feed belt 6 to move the paper forward. Inside the constraint shaft frame 11, the paper is constrained by the constraint shafts 12 through the two sets of constraint rollers 13, which constrains the movement of the paper.

[0025] The adjustment mechanism includes an adjusting screw 14, a screw plate 15, and a threaded sleeve 16. The adjusting screw 14 is longitudinally rotatably connected inside the slide 9. The front side of the adjusting screw 14 protrudes out and the front end of the adjusting screw 14 is connected to the middle of the rear end of the screw plate 15. The inner side of the slider 10 is connected to the outer side of the threaded sleeve 16. The inner wall of the threaded sleeve 16 is screwed to the outer wall of the adjusting screw 14. By turning the screw plate 15, the adjusting screw 14 can be rotated. The adjusting screw 14 is screwed into the threaded sleeve 16, which allows the slider 10 to move longitudinally under the constraint of the slide 9. The adjusting screw 14 and the threaded sleeve 16 are self-locking and fixed at any position by the threads of the adjusting screw 14 and the threaded sleeve 16.

[0026] It also includes an oil injection nozzle 17. An oil injection nozzle 17 is provided on the front side of the top of the threaded sleeve 16. The output end of the oil injection nozzle 17 is connected to the inner wall of the threaded sleeve 16. Oil can be injected into the inner wall of the threaded sleeve 16 through the oil injection nozzle 17 for convenient lubrication and maintenance.

[0027] It also includes an oil filling cap 18, and the outer side of the oil filling nozzle 17 and the inner side of the oil filling cap 18 can be detachably installed; after the oil filling cap 18 is installed on the outer side of the oil filling nozzle 17, the inside of the oil filling nozzle 17 can be sealed and protected, improving reliability.

[0028] It also includes an elastic belt 19, with a section of the inner side of the feed belt 6 connected to both sides of the elastic belt 19. When the constraint shaft frame 11 is in different longitudinal positions, the length of the feed belt 6 is inconsistent. The elastic belt 19 can adapt to the corresponding length of the feed belt 6 and always maintain elastic tightening, thereby improving reliability.

[0029] It also includes an information board 20, with the upper right side of the high shaft frame 2 connected to the inner side of the information board 20; the information board 20 can display the information of this device, making it easy to read and assisting in use, and improving convenience.

[0030] In summary, when using the feeding device of a transparent three-dimensional packaging machine, the adjusting screw 14 can be rotated by turning the screw plate 15 as needed. The adjusting screw 14 is screwed into the threaded sleeve 16, which connects to the slider 10, which moves longitudinally under the constraint of the slide 9. This, in turn, drives the constraint shaft frame 11 to move longitudinally. After reaching the desired position, the adjusting screw 14 and the threaded sleeve 16 are self-locking. The two sets of constraint rollers 13 inside the constraint shaft frame 11 contact the feeding belt 6 at this location, forming a corresponding angular arc. When the constraint shaft frame 11 is in different longitudinal positions, the length of the feeding belt 6 is inconsistent. The elastic belt 19 can adapt to the corresponding length of the feeding belt 6 and always maintain elastic tension during feeding. The paper sheet is inserted from the rear top of the feeding belt 6 and driven by the drive motor 4. The reducer 5 slows down the roller 7, which drives the belt roller 8 to rotate under the constraint of the short shaft frame 3. Another set of rollers 7 drives the belt roller 8 to rotate under the constraint of the high shaft frame 2. This action moves the feeding belt 6, causing the top side of the feeding belt 6 to move the paper sheet forward. Inside the constraint shaft frame 11, the paper sheet is constrained to rotate by the constraint shaft 12 through two sets of constraint rollers 13, thus constraining its movement. In addition, oil can be injected into the inner wall of the threaded sleeve 16 through the oiling nozzle 17 for convenient lubrication and maintenance. After installing the oiling cap 18 on the outside of the oiling nozzle 17, the inside of the oiling nozzle 17 can be sealed and protected. The information board 20 can display the information of this device for easy reading and auxiliary use, improving convenience.

[0031] The drive motor 4 and the reducer 5 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
