The "tube loading" operation before filling refers to the preliminary step of accurately transporting empty ointment tubes to the filling station and completing the positioning. Its efficiency and stability directly determine the capacity and product qualification rate of the entire filling production line.

[0003] Currently, while some semi-automatic equipment on the market can achieve autonomous feeding, workers still need to align the ointment tubes. This method not only consumes a lot of manpower, but also has limited speed, making it difficult to meet the needs of large-scale, high-efficiency production.

[0004] Therefore, this utility model provides an automatic tube feeding device for ointment filling equipment. Utility Model Content

[0005] To address the shortcomings of existing technology and solve the problem that while some semi-automatic equipment on the market can achieve autonomous feeding, workers still need to align the ointment tubes.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, an automatic tube feeding device for ointment filling equipment according to an embodiment of the present invention includes a base plate 1, on which an automatic mechanism is provided. The automatic mechanism includes: a tube feeding assembly, including a storage shell 2 fixed to the top of the base plate 1 by a set of first L-shaped columns, a top plate 3 slidably connected between the bottom inner walls of the storage shell 2, the top of the top plate 3 being inclined, and a slot 4 being opened on the top of the top plate 3, which is semi-circular and whose diameter matches the outer diameter of commonly used ointment tubes within a certain range; a lifting assembly for driving the top plate 3 to rise and fall is provided on the storage shell 2; and a conveying assembly, including a concave frame 5 fixed to the top of the base plate 1 by a set of second L-shaped columns, the concave frame 5 having a "U" shaped cross-section, a pair of support rods 6 connected to the concave frame 5 by an adjustment assembly, the support rods 6 being made of hard plastic, and the end of the support rods 6 near the storage shell 2 being inclined toward the opening of the storage shell 2; a conveyor belt 7 being provided between the opposite side walls of the concave frame 5, the length of which is the same as that of the concave frame, and a set of rectangular plates 8 fixed to the conveyor belt 7.

[0018] The lifting assembly includes a rectangular through groove 9 on the side wall of the storage shell 2, located in the middle of the side wall of the storage shell 2, a movable block 10 fixedly connected to the side wall of the top plate 3, the movable block 10 being slidably connected in the rectangular through groove 9, an isosceles rod 11 fixedly connected to the side wall of the movable block 10, horizontally fixed to the side of the movable block extending to the outside of the storage shell, and an isosceles groove 12 on the side wall of the isosceles rod 11.

[0019] An L-shaped plate 13 is fixedly attached to the side wall of the storage shell 2. A Z-shaped rod 14 is rotatably connected to one vertical end of the L-shaped plate 13 through a rotating hole. A first motor 15 is fixedly attached to the vertical side wall of the L-shaped plate 13 through the L-shaped rod. A stepper motor with a power of 0.5-1kW is selected, and the speed can be adjusted by the control system. The output end of the first motor 15 is driven and connected to one end of the Z-shaped rod 14. The end of the Z-shaped rod 14 away from the first motor 15 is movably connected in the isosceles groove 12.

[0020] During operation, by setting up the tube feeding component and the conveying component together, the ointment tube feeding operation can be carried out automatically without manual operation. This solves the problem that in the current technology, although some semi-automatic equipment on the market can achieve autonomous feeding, it still requires the operator to straighten the ointment tube. This method not only consumes a lot of manpower, but also has limited speed and cannot meet the needs of large-scale, high-efficiency production.

[0021] The adjustment assembly includes a concave block 16 fixed to the bottom of the concave frame 5, which has a "U" shape and an upward opening. A second motor 17 is fixed to the top of the concave block 16 laterally. The second motor is a servo motor with a power of 0.3-0.5kW and has forward and reverse rotation functions. It is used to drive the adjustment rod to rotate. The output end of the second motor 17 is provided with a drive rod 18. An adjustment rod 19 is fixed to the top of the drive rod 18.

[0022] Both ends of the adjusting rod 19 are rotatably connected to the connecting rod 20 via the first rotating shaft. The top of the connecting rod 20 away from the adjusting rod 19 is rotatably connected to the fixing block 26 via the second rotating shaft. A rectangular rod 21 is fixedly attached to the top of the fixing block 26.

[0023] Rectangular blocks 22 are fixed to both sides of the concave frame 5. Each rectangular block 22 has a sliding groove 23. A sliding block 24 is slidably connected in the sliding groove 23. The size of the sliding block 24 matches the sliding groove 23 and can slide smoothly along the sliding groove 23. A bracket 25 is fixed to the top of the sliding block 24. One end of the bracket 25 is fixed to the support rod 6. The bottom of the sliding block 24 is fixed to the top of the rectangular rod 21.

[0024] During operation, the spacing between the support rods 6 can be infinitely adjusted within a certain range through the linkage structure of the adjustment components, consisting of the second motor 17, drive rod 18, adjustment rod 19, connecting rod 20, and sliding block 24. This allows for adaptation to ointment tubes of various diameters. No replacement of the conveyor track or positioning components is required; specification switching can be completed solely through motor drive, significantly reducing switching speed and meeting the flexible needs of enterprises producing multiple types of ointments, thus improving the equipment's versatility and production flexibility.

[0025] Working principle: The operator first puts the empty ointment tubes to be loaded into the storage shell 2 in batches. Since the top plate 3 is inclined and the middle of the storage shell 2 is conical, the ointment tubes will automatically gather towards the slot 4 under the action of gravity. Finally, a single ointment tube is inserted into the slot 4 of the top plate 3. When the equipment receives the tube loading command, the lifting component starts first: the first motor 15 (fixed on the L-shaped rod of the L-shaped plate 13) starts to run, and its output end drives the Z-shaped rod 14 to rotate around the rotating hole at one vertical end of the L-shaped plate 13. Since the end of the Z-shaped rod 14 away from the first motor 15 is movably connected to the isosceles groove 12 of the isosceles rod 11, and the isosceles rod 11 is fixed to the top plate 3 by the moving block 10 (the moving block 10 slides and is restricted within the rectangular through groove 9 of the storage shell 2), the rotation of the Z-shaped rod 14 will be converted into a reciprocating pushing and pulling action on the isosceles rod 11. When the eccentric end of the Z-shaped rod 14 pushes the inner wall of the isosceles groove 12 upward, the isosceles rod 11 drives the moving block 10 to slide upward along the rectangular through groove 9, and then simultaneously drives the top plate 3 to move upward on the bottom inner wall of the storage shell 2. The single ointment tube locked in the slot 4 rises together with the top plate 3. When the top plate 3 rises to the preset height at the opening of the storage shell 2, the ointment tube can slide onto a pair of support rods 6, and support the edge of the ointment tube, so that the opening is facing upward. Then, the conveyor belt 7 can rotate, driving a set of rectangular plates 8 to move, pushing the ointment tube to the bottom of the filling equipment for filling.

[0026] To accommodate ointment tubes of different diameters, the adjustment assembly is activated to adjust the spacing of the support rods 6: the second motor 17 (fixed on the concave block 16 at the bottom of the concave frame 5) operates, and its output end drives the drive rod 18 to rotate. The drive rod 18 simultaneously drives the top adjustment rod 19 to rotate around the axis of the drive rod 18. Since both ends of the adjustment rod 19 are hinged to the two connecting rods 20 through the first rotating shaft, and the end of the connecting rod 20 away from the adjustment rod 19 is hinged to the rectangular rod 21 through the second rotating shaft, the rotation of the adjustment rod 19 will push or pull the rectangular rod 21 laterally through the connecting rod 20. The top of the rectangular rod 21 is fixed to the sliding block 24 (the sliding block 24 is limited to sliding through the sliding grooves 23 of the rectangular blocks 22 on both sides of the concave frame 5). Therefore, the lateral movement of the rectangular rod 21 will drive the sliding block 24 to slide along the sliding grooves 23. The bracket 25 at the top of the sliding block 24 simultaneously drives the support rods 6 to move laterally, adjusting the spacing between the pair of support rods 6 to accommodate ointment tubes of different sizes.
