Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular to a stopper mounting structure for bottles. Background Technology

[0002] Currently, in the production, filling, and packaging of bottle containers, it is usually necessary to install a soft rubber sleeve (such as silicone, elastomer, etc.) at the bottle mouth to achieve sealing, dustproof, or leak-proof functions. The common installation method is to embed the rubber sleeve into the bottle mouth with an interference fit, that is, the outer diameter of the rubber sleeve is slightly larger than the inner diameter of the bottle mouth. The elastic deformation of the rubber material makes it fit tightly against the inner wall of the bottle mouth, thereby forming a stable fixation and sealing effect.

[0003] However, this installation method has the following technical problems in actual production:

[0004] High assembly resistance: Because the outer diameter of the rubber sleeve is larger than the inner diameter of the bottle mouth, a large external force is required during installation to compress and deform the rubber sleeve and embed it into the bottle mouth, resulting in low assembly efficiency.

[0005] High difficulty in automated production: On high-speed filling or packaging lines, the precise alignment and stable embedding of rubber sleeves require high-precision mechanical devices; otherwise, problems such as skewing, folding, or springback may occur, affecting the yield rate.

[0006] Therefore, there is an urgent need to provide a method that can reduce the difficulty of inserting rubber sleeves while ensuring sealing and fixing strength, thereby improving production efficiency and product reliability. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a stopper installation structure for a bottle body, which solves the technical problem that the rubber sleeve is difficult to embed into the bottle body.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A stopper mounting structure for a bottle includes: a frame for supporting the stopper mounting structure; a turntable mounted on the frame for conveying the bottle; a cleaning assembly mounted on the frame for cleaning the bottle; a feeding assembly mounted on the frame for feeding a rubber sleeve onto the turntable; and a pressing assembly mounted on the frame for pressing the rubber sleeve into the bottle.

[0010] Furthermore, the cleaning assembly includes a lifting plate and a lifting cylinder. The lifting cylinder is vertically mounted on the frame, and the lifting plate is mounted on the piston rod of the lifting cylinder. A dust suction hood is provided on the lifting plate, and an air extraction pipe is connected to the dust suction hood. One end of the air extraction pipe is connected to the dust suction hood, and the other end extends away from the dust suction hood.

[0011] Furthermore, the feeding assembly includes a feeding frame, which is mounted on the machine frame. The feeding frame is provided with a feeding block and a feeding cylinder. The feeding cylinder is mounted on the feeding frame, and the feeding block is mounted on the piston rod of the feeding cylinder. The feeding block has a feeding hole.

[0012] Furthermore, the feeding rack is provided with a feeding pipe, one end of which forms an outlet end, and the outlet end faces the side close to the feeding block.

[0013] Furthermore, the feeding assembly includes a sliding frame, on which a first sliding cylinder and a second sliding cylinder are mounted. The first sliding cylinder is horizontally mounted on the frame, and the second sliding cylinder is vertically mounted on the first sliding cylinder. The sliding frame is mounted on the first sliding cylinder. A picking cylinder is mounted on the sliding frame. The picking cylinder is mounted on the sliding frame, and a picking rod is provided on the piston rod of the picking cylinder. A picking air hole is formed in the picking rod. The picking cylinder is connected to an external air extraction pipe.

[0014] Furthermore, a material trough is provided between the feeding block and the turntable, and a through hole is provided on the material trough, which communicates with the material trough, and lubricating fluid is placed in the material trough.

[0015] Furthermore, the pressing assembly includes a pressing cylinder, which is vertically mounted on the frame. A clamping cylinder is provided on the piston rod of the pressing cylinder, and a pressing rod is provided on the piston rod of the clamping cylinder. A pressing hole is formed on the pressing rod, and the pressing assembly is connected to an external air extraction pipe.

[0016] In summary, this application includes at least one of the following beneficial technical effects of the stopper mounting structure for bottle bodies:

[0017] During use, the turntable is mounted on the frame and the bottle is placed on the turntable for conveying. As the turntable drives the bottle to rotate on the frame, the cleaning component on the frame cleans the bottle to reduce dust on the bottle. The feeding component places the rubber sleeve on the bottle, and then the pressing component presses the rubber sleeve into the bottle. This eliminates the need for manual pressing of the rubber sleeve, reduces the difficulty of embedding the rubber sleeve, and improves production efficiency and product reliability.

[0018] The installation of the feeding block, feeding cylinder, and feeding pipe improves the ease of conveying the rubber sleeve to the turntable.

[0019] The stability of the rubber sleeve pressed onto the bottle body is improved by using the material-taking air hole on the material-taking rod and the setting of the clamping cylinder and the material-pressing hole. Attached Figure Description

[0028] In order 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.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses a stopper mounting structure for a bottle.

[0031] Reference Figure 1 and Figure 7 A stopper installation structure for bottles includes a frame 1, on which a turntable 2 is mounted and rotatably. The frame 1 is equipped with a cleaning component 3, a feeding component 4, and a pressing component 5. The cleaning component 3 cleans the bottle, the feeding component 4 feeds a rubber sleeve to the turntable 2, and the pressing component 5 presses the rubber sleeve firmly onto the bottle. This eliminates the need for manual insertion of the rubber sleeve, reduces the difficulty of inserting the sleeve, and improves production efficiency and product reliability.

[0032] Turntable 2 is rotatably mounted on frame 1. A drive motor 11 is mounted on frame 1, and its output shaft is connected to turntable 2. In use, drive motor 11 drives turntable 2 to rotate. Positioning blocks 21 are provided on turntable 2, secured to it with bolts. Several positioning blocks 21 are spaced apart around turntable 2, each with a positioning groove 22. In use, the bottle is placed in the positioning groove 22 of the positioning block 21, and the bottle rotates with turntable 2.

[0033] Reference Figure 2 During use, a small amount of dust may accumulate inside the bottle. If the rubber sleeve is directly installed on the bottle, the dust will be trapped inside. Therefore, the cleaning component 3 includes a lifting cylinder 31 and a lifting plate 32. The lifting cylinder 31 is vertically mounted on the frame 1, and the piston rod of the lifting cylinder 31 faces the side closer to the turntable 2. A dust suction hood 33 is provided on the piston rod of the lifting cylinder 31, and an air suction pipe 34 is installed on the dust suction hood 33. One end of the air suction pipe 34 is connected to the dust suction hood 33, and the other end extends away from the dust suction hood 33.

[0034] Furthermore, a vacuum tube 35 is provided inside the vacuum hood 33. One end of the vacuum tube 35 is connected to the vacuum hood 33. When in use, one end of the vacuum tube 35 is inserted into the bottle. When in use, the vacuum tube 35 draws out the dust from the bottle, reducing the amount of dust adhering to the bottle.

[0035] Reference Figures 3-4 and Figure 6 After the dust inside the bottle is removed, the rubber sleeve needs to be placed on the bottle. The feeding assembly 4 includes a feeding rack 41, which is installed on the side of the frame 1 near the turntable 2. The feeding rack 41 is equipped with a feeding block 42 and a feeding cylinder 43. The feeding cylinder 43 is horizontally installed on the feeding rack 41, and the feeding block 42 is connected to the piston rod of the feeding cylinder 43. The feeding cylinder 43 drives the feeding block 42 to slide on the feeding rack 41.

[0036] Furthermore, a feeding pipe 44 is installed on the feeding rack 41. The feeding pipe 44 is connected to an external vibrating plate via a pipeline. During use, the vibrating plate continuously feeds rubber sleeves onto the feeding pipe 44. One end of the feeding pipe 44 forms an outlet end 441, which faces the side near the feeding block 42. The feeding block 42 has a feeding hole 421. The feeding block 42 is configured such that, in the first position, the feeding hole 421 on the feeding block 42 is aligned with the outlet end 441 on the feeding pipe 44, allowing material to fall from the feeding pipe 44 into the feeding hole 421. After the material falls into the feeding hole 421, the feeding block 42 moves towards the side near the turntable 2 under the drive of the feeding cylinder 43. In the second position, the upper surface of the feeding block 42 closes the outlet end 441 of the feeding pipe 44, preventing material from falling.

[0037] A sliding frame 45 is mounted on the frame 1, sliding between the loading block 42 and the turntable 2. To improve the ease of sliding the sliding frame 45 on the frame 1, a first sliding cylinder 46 and a second sliding cylinder 461 are mounted on the frame 1. The first sliding cylinder 46 is horizontally mounted on the frame 1, and the second sliding cylinder 461 is vertically mounted on the first sliding cylinder 46. The sliding frame 45 is mounted on the piston rod of the second sliding cylinder 461. In use, the first sliding cylinder 46 drives the second sliding cylinder 461 to move horizontally, and the second sliding cylinder 461 drives the sliding frame 45 to move towards the side closer to the turntable 2.

[0038] A material-picking cylinder 451 is installed on the sliding frame 45. The material-picking cylinder 451 is mounted on the sliding cylinder, and a material-picking rod 452 is installed on the piston rod of the material-picking cylinder 451. A material-picking air hole 453 is formed inside the material-picking rod 452. In use, the material-picking rod 452 is moved above the feeding hole 421 of the feeding block 42 under the drive of the first sliding cylinder 46 and the second sliding cylinder 461. Then, the material-picking cylinder 451 drives the material-picking rod 452 to pass into the rubber sleeve, and the material-picking rod 452 lifts the rubber sleeve.

[0039] Furthermore, to improve the ease of installing the rubber sleeve on the bottle, a material trough 12 is installed between the feeding block 42 and the turntable 2. The material trough 12 has a through hole 13 that communicates with it. The material trough 12 contains lubricating fluid, preferably alcohol, which provides lubrication and is also volatile, thus minimizing contamination of the bottle. After the picking rod 452 removes the rubber sleeve from the feeding block 42, it immerses the rubber sleeve through the through hole 13 into the alcohol in the material trough 12 before placing it on the bottle.

[0040] Furthermore, the material-receiving air port 453 is connected to an external air extraction device. When the material-receiving rod 452 places the rubber sleeve at the bottle opening, the material-receiving cylinder 451 extracts air from the bottle. As the gas inside the bottle is extracted, the rubber sleeve slowly moves into the bottle. When the rubber sleeve is partially embedded in the bottle, the material-receiving rod 452 separates from the rubber sleeve under the drive of the material-receiving cylinder 451. By initially pressing the rubber sleeve into the bottle, on the one hand, the risk of the rubber stopper falling off the bottle when the turntable 2 rotates is reduced; on the other hand, the efficiency of subsequent rubber stopper pressing is improved.

[0041] Reference Figures 5-6 The pressing assembly 5 includes a pressing cylinder 51, which is vertically mounted on the frame 1 with its piston rod facing towards the turntable 2. A clamping cylinder 52 is located at one end of the piston rod of the pressing cylinder 51, and a pressing rod 53 is located at the other end of the piston rod of the clamping cylinder 52. A pressing hole 54 is formed on the pressing rod 53, which is connected to an external vacuum device. In use, the pressing cylinder 51 drives the clamping cylinder 52 to move towards the side closer to the bottle body. Then, the clamping cylinder 52 drives the pressing rod 53 to penetrate the rubber stopper. External vacuum then evacuates the bottle body through the pressing hole 54 on the pressing rod 53. As the gas in the bottle is extracted, the rubber stopper is completely inserted into the bottle body. This eliminates the need to directly press the rubber stopper into the bottle body, reducing damage to the rubber stopper.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
