Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery and equipment technology, specifically to an aluminum-plastic cap hanging head structure. Background Technology

[0002] After filling pharmaceutical bottles such as vials, oral liquid bottles, and plastic bottles, capping and crimping are required. Specifically, after liquid or powdered medicine is filled into the bottle, in order to ensure the airtightness of the medicine, a process of capping with a rubber stopper, capping with an aluminum-plastic cap, and crimping is required. Among them, the action of capping with an aluminum-plastic cap is usually as follows: the aluminum-plastic cap is placed into the aluminum-plastic cap slide in a certain direction, and the tilt of the end of the slide, i.e., the cap hanging head, causes the stationary and tilted aluminum-plastic cap to be hooked onto the moving mouth of the medicine bottle, thus completing the capping action.

[0003] The existing cap-hanging head structure is relatively simple, with a fixed bottom positioning plate that limits the bottom surface of the aluminum-plastic cap. The fixing point for the outer diameter of the aluminum-plastic cap is at the point of maximum diameter, i.e., the top outer side of the cap. This existing cap-hanging head structure presents two problems that are difficult for the industry to solve: First, because the bottom positioning plate needs to prevent the cap from falling off, it must cover at least half of the cap's area. This results in the intersection between the tilted cap and the bottle mouth being too small. The stress point when the cap is attached to the bottle is usually the rubber stopper at the bottle mouth, posing a risk of the stopper being pulled off. Second, because the aluminum-plastic cap is wider at the top and narrower at the bottom, with the fixing point for the outer diameter located at the upper, larger diameter position, when the cap is attached, the stress point when pulling the cap out of the hanging head is at the bottom, often causing the cap to rotate around the fixing point and fail to hang properly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an aluminum-plastic cap hanging head structure.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An aluminum-plastic cap hanging head structure includes a cap hanging track, a slide back plate fixedly connected to the lower part of the cap hanging track, forming a slide between the two, and a buffer spring plate, which is hinged to the head of the cap hanging track and is provided with a buffer spring relative to the cap hanging track. The head of the hanging cover track is hinged with tightening blocks on both sides. The rotation center axis of the tightening blocks is perpendicular to the rotation center axis of the buffer spring plate. An outer diameter tension spring is connected between the two tightening blocks. An outer diameter positioning plate is connected to the lower part of the two tightening blocks respectively. Lower positioning plates are fixedly installed on both sides of the head of the cover track, and both lower positioning plates are located inside the cover track.

[0006] In the above structure, the slide formed by the cap mounting track and the slide back plate is the material feeding channel for the aluminum-plastic cap. At the head of the slide, the aluminum-plastic cap is hooked onto the linearly moving bottle. The buffer spring plate in the above structure is used to position the top surface of the aluminum-plastic cap, the outer diameter positioning plate at the bottom of the tightening block is used to limit the small diameter outer wall of the aluminum-plastic cap, and the two lower positioning plates are used to support the stepped surface at the junction of the large and small diameter outer walls of the aluminum-plastic cap.

[0007] A column is fixedly connected to the top of the hanging cover track. A buffer spring is sleeved on the outside of the column. A boss is provided on the top of the column. One end of the buffer spring is fixed to the position of the buffer plate, and the other end is pressed against the lower surface of the boss.

[0008] Specifically, the top of the buffer plate is connected to a horizontal plate, which is set on the upper part of the cover track. The horizontal plate has a strip-shaped through hole, and the column is slidably set in the through hole. The buffer spring is connected to the horizontal plate.

[0009] A pressure plate is fixedly connected to the head of the cover track. The pressure plate is fixedly installed on the upper side of the head of the cover track. The rotation center axis of the buffer spring plate and the rotation center axis of the two tightening blocks are rotatably connected to the pressure plate.

[0010] During installation, the head of the hanging cover track is provided with a recessed opening, and one end of the buffer plate is installed inside the opening.

[0011] The head of the slide back plate is fixedly connected to two mounting posts, and the lower positioning plate is fixedly installed on the upper part of the mounting posts.

[0012] The top of the tightening block is provided with a barb, and the two ends of the outer diameter tension spring are respectively hooked to the barb.

[0013] The beneficial effects achieved by this utility model are: This invention utilizes the structural feature of the aluminum-plastic cap, which is larger at the top and smaller at the bottom. A lower positioning plate is used to support the stepped surface of the aluminum-plastic cap, so the bottom of the aluminum-plastic cap does not need much support. As a result, the bottom of the aluminum-plastic cap can protrude more relative to the slide back plate, thus significantly increasing the area for hooking with the bottle mouth. The force point of the bottle mouth is changed from the rubber stopper to the bottle, and the rubber stopper of the bottle will not be snagged off.

[0014] In this invention, the two outer diameter positioning plates are fixed to the small diameter outer wall of the lower part of the aluminum-plastic cover, so that the fixing point of the outer wall of the aluminum-plastic cover is lower, making it less likely for the aluminum-plastic cover to rotate during the hanging process, thereby improving the success rate of hanging the cover.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: like Figures 1-8 As shown, an aluminum-plastic cap hanging head structure includes a cap hanging track 1, and a slide back plate 2 is fixedly connected to the lower part of the cap hanging track 1, forming a slide between the two, providing a channel for the aluminum-plastic cap 11 to be unloaded, which is an existing structure.

[0019] The aluminum-plastic cap hanging head structure also includes a buffer spring plate 3. The head of the hanging track 1 is provided with a concave opening, and the buffer spring plate 3 is hinged to the inside of the opening at the head of the hanging track 1.

[0020] The buffer plate 3 is equipped with a buffer spring 8 relative to the cover track 1. Specifically, a column 7 is fixedly connected to the top of the cover track 1, and the buffer spring 8 is sleeved on the outside of the column 7. A boss is provided on the top of the column 7. One end of the buffer spring 8 is fixed to the position of the buffer plate 3, and the other end presses against the lower surface of the boss. A horizontal plate 9 is connected to the top of the buffer plate 3. The horizontal plate 9 is located on the upper part of the cover track 1. A strip-shaped through hole is opened on the horizontal plate 9. The column 7 is slidably installed in the through hole, and the buffer spring 8 is connected to the horizontal plate 9.

[0021] The head of the hanging cover track 1 is hinged with tightening blocks 4 on both sides. The rotation center axis of the tightening block 4 is perpendicular to the rotation center axis of the buffer plate 3. An outer diameter tension spring 6 is connected between the two tightening blocks 4. The lower part of the two tightening blocks 4 is connected with an outer diameter positioning plate 5.

[0022] like Figure 6 , Figure 7 As shown, lower positioning plates 13 are fixedly installed on both sides of the head of the cover track 1, and both lower positioning plates 13 are located inside the cover track 1. Two mounting posts 14 are fixedly connected to the head of the slide back plate 2, and the lower positioning plates 13 are fixedly installed on the upper part of the mounting posts 14.

[0023] In the above structure, the slide formed by the cap track 1 and the slide back plate 2 is the feeding channel for the aluminum-plastic cap 11. At the head of the slide, the aluminum-plastic cap 11 is hooked to the linearly moving bottle 12. The buffer spring plate 3 in the above structure is used to position the top surface of the aluminum-plastic cap 11, the outer diameter positioning plate 5 at the bottom of the tightening block 4 is used to limit the small diameter outer wall of the aluminum-plastic cap 11, and the two lower positioning plates 13 are used to support the stepped surface at the junction of the large and small diameter outer walls of the aluminum-plastic cap 11.

[0024] like Figure 2 , Figure 8 As shown, a pressure plate 10 is fixedly connected to the head of the cover track 1. The pressure plate 10 is fixedly installed on the upper side of the head of the cover track 1. The rotation center axis of the buffer spring plate 3 and the rotation center axis of the two tightening blocks 4 are rotatably connected to the pressure plate 10.

[0025] The top of the tightening block 4 is provided with a barb, and the two ends of the outer diameter tension spring 6 are respectively hooked to the barb.

[0026] The operation process of this utility model is as follows: During operation, the aluminum-plastic cover 11 slides from top to bottom through the channel formed by the cover rail 1 and the slide back plate 2, that is, it slides to the head of the cover rail 1. At this time, the aluminum-plastic cover 11 becomes tilted (e.g., Figure 4 , Figure 7(As shown). The aluminum-plastic cap 11 is an aluminum-plastic composite cap, specifically a cylindrical cap with a larger upper diameter and a smaller lower diameter, and its outer wall has a stepped surface. During the sliding process, the aluminum-plastic cap 11 changes from being supported at its bottom by the slide back plate 2 to being supported at its stepped surface by the lower positioning plate 13. At this time, in the axial direction, the lower limit of the aluminum-plastic cap 11 is limited by the stepped surface located in the middle of the aluminum-plastic cap 11, and the top is limited by the buffer spring plate 3. Due to the action of the buffer spring 8, the buffer spring plate 3 and the aluminum-plastic cap 11 together can have a certain amount of movement, which facilitates the realization of the hooking action.

[0027] Because the minimum distance between the two outer diameter positioning plates 5 is less than the small diameter of the aluminum-plastic cover 11, the aluminum-plastic cover 11 will stop sliding when it contacts the outer diameter positioning plates 5. Since the outer diameter positioning plates 5 are mounted on the left and right tightening blocks 4, and the two tightening blocks 4 are equipped with outer diameter tension springs 6 and can move around their rotation axis, the outer diameter positioning plates 5 have a certain degree of outward elasticity. When the aluminum-plastic cover 11 is tilted to the left (…),… Figure 5 When the bottle 12 (in the direction shown) is hooked and pulled, it can be pulled out from the cap head. The bottle 12 is driven by the conveyor belt to achieve continuous movement.

[0028] The significant advantage of this utility model is that by utilizing the different diameters of the upper and lower parts of the aluminum-plastic cap 11, the limiting position of the aluminum-plastic cap 11 is raised from the bottom of the cap to the middle step, allowing most of the bottom of the aluminum-plastic cap 11 to be exposed for hooking with the mouth of the medicine bottle. In this way, at the same tilt angle, the hooking depth of the structure of this utility model is significantly greater than that of the existing structure, which can completely avoid the rubber stopper being subjected to force, thereby preventing the rubber stopper from being pulled out of the bottle mouth.

[0029] In addition, the hanging head structure of this utility model changes the left and right fixing points on the outer wall of the aluminum-plastic cap 11 to a lower, smaller diameter position. This reduces the height difference between the force point on which the aluminum-plastic cap 11 is pulled out of the hanging head by the medicine bottle and the left and right fixing points. In actual use, the problem of the aluminum-plastic cap 11 flipping over is almost non-existent.
