Description

Technical Field

[0001] This utility model belongs to the field of aluminum ointment tube assembly technology, and relates to an assembly device for an aluminum ointment tube with a plastic liner. Background Technology

[0002] Aluminum ointment tubes are a common packaging container, particularly suitable for packaging ointments, cosmetics, and other products. Although the aluminum surface is protected by an oxide film, certain medications or hair dye ingredients (such as acidic, alkaline substances, or oxidizing agents) can damage the oxide layer, triggering chemical reactions that lead to the degradation of active ingredients or the generation of harmful substances. To protect the structural integrity of aluminum ointment tubes and extend their lifespan, a plastic bushing (such as an inert material like PE or PP) is placed inside. This plastic bushing isolates the product from direct contact with the aluminum, ensuring chemical stability. Therefore, an assembly device is needed to press the plastic bushing into the aluminum ointment tube.

[0003] A metal bushing and plastic bushing pressing assembly device disclosed in Chinese patent CN211916023U includes a rotary separator, a first vibrating plate, a second vibrating plate, a first gripping mechanism and a second gripping mechanism. The rotary separator is fixedly installed on a base frame. A rotatable pre-installation plate is provided inside the rotary separator. The end of the first discharge groove on the first vibrating plate is located on one side of the rotary separator, and the end of the second discharge groove on the second vibrating plate abuts against the outside of the rotary separator.

[0004] When using this assembly device, the plastic bushing and the metal bushing need to be moved separately, and then the first gripper and the second gripper are used to grasp and assemble them. This requires moving the plastic bushing and the metal bushing multiple times, making the operation inconvenient.

[0005] To address the aforementioned problems, this utility model proposes an assembly device for an aluminum ointment tube with a plastic liner. Utility Model Content

[0035] 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.

[0036] like Figures 1-9As shown, the technical solution adopted by this utility model is as follows: an assembly device for an aluminum ointment tube with a plastic liner, comprising two symmetrically arranged support frames 28, and a chain 11 is provided on the side of the two support frames 28 that are close to each other.

[0037] Each of the two support frames 28 is rotatably connected to a connecting shaft at both ends. The two connecting shafts are arranged in parallel, and sprockets 27 are fixedly sleeved at both ends of each connecting shaft. One chain 11 is driven and sleeved on the two sprockets 27 at the same end of the two connecting shafts, while the other chain 11 is driven and sleeved on the other two sprockets 27. Through the cooperation of the two chains 11, the two connecting shafts rotate synchronously.

[0038] One of the support frames 28 is fixedly connected to one side of a first motor 12, which drives one of the connecting shafts to rotate. When one of the connecting shafts rotates, the two connecting shafts rotate together through the transmission of the sprocket 27 and the chain 11.

[0039] Several rollers 10 are fixedly connected at intervals between the two chains 11. When the two chains 11 move, they will drive the rollers 10 to move together. The two support frames 28 are equipped with extrusion assemblies, which are located on top of the rollers 10.

[0040] The extrusion assembly includes a pusher plate 13 and a baffle plate 9. The baffle plate 9 is fixedly connected to one side of one of the support frames 28, and is located directly above the end of the roller 10. A protrusion is fixedly connected to the top of the other support frame 28, and a push rod 30 slides horizontally through the protrusion. The pusher plate 13 is fixedly connected to the end of the push rod 30 near the baffle plate 9. The pusher plate 13 is positioned by sliding the push rod 30 on the protrusion.

[0041] A fixed plate 17 is fixedly mounted on one side of a support frame 28 with a protrusion, and a second motor 16 is fixedly connected to one side of the fixed plate 17. The output shaft of the second motor 16 rotates through the fixed plate 17, and a second connecting rod 15 is fixedly connected to the end of the output shaft of the second motor 16. The other end of the second connecting rod 15 is rotatably connected to a first connecting rod 14, and the other end of the first connecting rod 14 is hinged to the other end of the push rod 30. The output shaft of the second motor 16 drives the second connecting rod 15 to rotate, and the other end of the second connecting rod 15 pushes the first connecting rod 14, causing the other end of the first connecting rod 14 to push the push rod 30 to slide back and forth.

[0042] Both of the two support frames 28 have a feeding star wheel 1 rotatably mounted on the same end of their adjacent sides, and both feeding star wheels 1 are located at the end of the chain 11. This positions the feeding star wheel 1 at a roller 10 at the end of the chain 11 to facilitate the feeding of material onto the roller 10.

[0043] A rotating shaft 23 is rotatably connected between the two support frames 28. The two ends of the rotating shaft 23 rotatably pass through the corresponding support frame 28, and the two feeding star wheels 1 are fixedly sleeved on the rotating shaft 23. The rotating shaft 23 enables the two feeding star wheels 1 to rotate synchronously.

[0044] A third motor 24 is fixedly connected to one of the support frames 28, and a belt drive assembly 6 is provided between the output shaft of the third motor 24 and the rotating shaft 23. The third motor 24 drives the rotating shaft 23 to rotate through the belt drive assembly 6. The belt drive assembly 6 consists of a belt tightly fitted onto two pulleys. The belt drive assembly 6 is prior art and will not be described in detail here.

[0045] The outer surfaces of the two feeding star wheels 1 are evenly provided with several arc-shaped grooves 19, and each groove 19 is provided with a set of ventilation holes.

[0046] An aluminum ointment tube 2 is disposed within a groove 19 of one of the feeding star wheels 1. A plastic bushing 3 is disposed within a groove 19 of the other feeding star wheel 1. The shape of the groove 19 is adapted to fit the shapes of the aluminum ointment tube 2 and the plastic bushing 3. One end of the plastic bushing 3 has an arc-shaped chamfer, and the outer diameter of the plastic bushing 3 is slightly smaller than the inner diameter of the aluminum ointment tube 2, so that the plastic bushing 3 can enter the interior of the aluminum ointment tube 2 through the arc-shaped chamfered end. Both the aluminum ointment tube 2 and the plastic bushing 3 are movably disposed between two adjacent rollers 10, so that the plastic bushing 3 can be pushed into the aluminum ointment tube 2 between the two rollers 10 to achieve the purpose of assembly.

[0047] Each of the support frames 28 is equipped with an adsorption component at the feeding star wheel 1, and the adsorption component is connected to the corresponding ventilation hole. The adsorption component generates suction through the ventilation hole, fixing the aluminum ointment tube 2 or plastic bushing 3 onto the groove 19.

[0048] Each of the support frames 28 is fixedly provided with a suction plate 21 at the feeding star wheel 1. The feeding star wheel 1 is rotatably disposed on one side of the corresponding suction plate 21, and the suction plate 21 is in a sealed sliding fit with the feeding star wheel 1.

[0049] Each of the two support frames 28 has a fixed rod 22 fixedly connected to one side of its adjacent side, and two suction discs 21 are respectively fixedly connected to the ends of the corresponding fixed rods 22. A rotating shaft 23 passes through the two suction discs 21. The suction discs 21 are fixed between the two support frames 28 by the fixed rods 22, so that the feeding star wheel 1 rotates on one side of the suction disc 21.

[0050] Ventilation slots 25 are provided on the side of the two suction plates 21 that are close to each other. Both ventilation slots 25 are provided with arc-shaped openings, and the openings are located at the top of one side of the suction plate 21.

[0051] Each set of ventilation holes includes several spaced-apart air intakes 20. Inside the feeding star wheel 1, an air passage 29 is provided at each groove 19, and the air passage 29 communicates with the corresponding air intakes 20. The end of the air passage 29 passes through the end of the feeding star wheel 1 near the suction plate 21, and the end of each air passage 29 can communicate with the ventilation slot 25. The air passage 29 can communicate with the ventilation slot 25 through its opening, but as the feeding star wheel 1 rotates, the air passage 29 leaves the opening and no longer communicates with the ventilation slot 25.

[0052] The adsorption assembly includes a vacuum pump 5, which is fixedly connected to one side of the support frame 28. The vacuum pump 5 is equipped with one inlet and one outlet suction nozzle and one exhaust nozzle, and is capable of continuously creating a vacuum or negative pressure at the inlet. The vacuum pump 5 is an existing product. A suction pipe is fixedly connected to the inlet end of the vacuum pump 5, and the suction pipe passes through the support frame 28. When the vacuum pump 5 is started, it draws air through the suction pipe.

[0053] Each of the suction discs 21 has an opening 26 located in the ventilation slot 25, and the opening 26 is connected to the ventilation slot 25. One end of the suction pipe is fixedly connected to the opening 26. The suction pipe draws air from the ventilation slot 25 through the opening 26, and then generates suction at the suction port 20 through the air passage 29.

[0054] A fixing frame 7 is fixedly connected between the two support frames 28, and two sensors 8 are symmetrically fixedly connected to the fixing frame 7. The sensors 8 are through-beam sensors, which can detect whether the aluminum ointment tube 2 or the plastic bushing 3 is missing between the two rollers 10.

[0055] One of the support frames 28 is fixedly connected to one side of an air pump 18, and an air pipe 4 is fixedly connected to the air outlet of the air pump 18. The air pipe 4 is a universal bamboo-joint tube, which is a pipe made up of segments stacked together, similar to the structure of bamboo, and can be freely bent and positioned. This allows for adjustment of the angle of the air outlet of the air pipe 4 so that the air outlet faces the plastic bushing 3 on the top of the roller 10, so as to blow away any missing or misaligned aluminum ointment tube 2 or plastic bushing 3.

[0056] Working principle:

[0057] When in use, the air pump 5 is started, and the air pump pipe at the input end of the air pump 5 generates suction through the opening 26, ventilation slot 25, air passage 29, and air inlet 20. The air passage 29 and air inlet 20, which are not connected to the ventilation slot 25, have no suction, and the air passage 29 without suction is located near the roller 10.

[0058] The aluminum ointment tube 2 is placed in the groove 19 of a feeding star wheel 1 near the baffle 9. The suction port 20 on the groove 19 where the aluminum ointment tube 2 is placed has suction, which will fix the aluminum ointment tube 2 in the groove 19. Similarly, the plastic bushing 3 is fixed in the groove 19 of another feeding star wheel 1.

[0059] The first motor 12 is started, causing a connecting shaft connected to the first motor 12 to rotate, which in turn causes the sprocket 27 to rotate. Through the transmission of the chain 11, the two connecting shafts rotate together. This, in turn, causes several rollers 10 to move.

[0060] The third motor 24 is started, which drives the rotating shaft 23 to rotate through the belt drive assembly 6, causing the two feeding star wheels 1 to rotate. The feeding star wheels 1 will drive the aluminum ointment tube 2 and the plastic bushing 3 to move, so that the end of the air channel 29 moves to one side of the suction plate 21.

[0061] The aluminum ointment tube 2 and plastic bushing 3 gradually move towards the top of the roller 10, and the air passage 29, which is connected to the ventilation groove 25, gradually moves away from the arc-shaped opening of the ventilation groove 25. After the end of the air passage 29 is no longer connected to the ventilation groove 25, the suction port 20 no longer generates suction, and at this time, the aluminum ointment tube 2 and plastic bushing 3 will fall between the two rollers 10. During this process, the aluminum ointment tube 2 and plastic bushing 3 are continuously added to the upward feeding star wheel 1.

[0062] Chain 11 drives roller 10, aluminum ointment tube 2, and plastic bushing 3 to move. Aluminum ointment tube 2 moves to the side closer to baffle 9, and plastic bushing 3 moves to the side closer to push plate 13. After a suitable number of plastic bushings 3 have moved to the side of push plate 13, the first motor 12 and the third motor 24 are turned off, chain 11 stops moving, and feeding star wheel 1 stops rotating.

[0063] The second motor 16 is started, and its output shaft drives the second connecting rod 15 to rotate. The second connecting rod 15 pulls one end of the first connecting rod 14, and the other end of the first connecting rod 14 pushes the push rod 30 to slide on the protrusion, thereby pushing the push plate 13 to move closer to the baffle 9. The push plate 13 pushes the plastic bushing 3 into the corresponding aluminum ointment tube 2, and also moves the aluminum ointment tube 2. This continues until the end of the aluminum ointment tube 2 contacts the baffle 9, pushing the plastic bushing 3 into the aluminum ointment tube 2.

[0064] Because the aluminum ointment tube 2 has a certain degree of hardness, and the plastic bushing 3 is pushed in along the axial direction of the aluminum ointment tube 2, the aluminum ointment tube 2 is not easily deformed during assembly.

[0065] After assembly, roller 10 continues to move, and feeding star wheel 1 continues to rotate. During the conveying process of aluminum ointment tube 2 and plastic bushing 3, sensor 8 continuously detects whether there is a missing aluminum ointment tube 2 or plastic bushing 3.

[0066] If any part is missing, start the air pump 18 to blow away the missing aluminum ointment tube 2 or plastic bushing 3.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
