Description

Technical Field

[0001] This utility model belongs to the field of glass bottle processing technology, specifically a rotary clamping device for glass bottle processing. Background Technology

[0002] Glass bottles are transparent or semi-transparent rigid containers made primarily from inorganic non-metallic minerals such as quartz sand, soda ash, limestone, and feldspar. They are produced through processes including crushing, mixing, high-temperature melting (above 1500℃), molding (such as blowing and pressing), and heat treatment (annealing). They are widely used in the food (such as wine, canned goods, and beverages), pharmaceutical (such as medicine bottles and infusion bottles), daily chemical (such as cosmetic bottles), and chemical (such as reagent bottles) industries, and are one of the most important packaging materials.

[0003] The most common type of glass bottle is a cylindrical bottle with a circular cross-section and a vertical line in the height direction. In the production and processing of cylindrical glass bottles, it is often necessary to clamp and fix them and allow them to rotate to meet different processing requirements, such as frosting, labeling, and painting.

[0004] Existing rotary clamping equipment cannot adapt to clamping cylindrical glass bottles of different diameters, resulting in poor versatility. Furthermore, it typically clamps only the outer wall, causing interference during processing such as frosting, labeling, and painting of the bottle's exterior, thus limiting its flexibility. Additionally, some clamping devices lack sufficient clamping stability, exhibiting uneven clamping force distribution, which can easily lead to bottle wobbling or falling during rotation. Utility Model Content

[0005] To address the shortcomings of traditional rotary clamping devices, which cannot adapt to different diameters of cylindrical glass bottles and have poor versatility, and which typically clamp the outer wall of the glass bottle, causing interference during processing, this invention provides a rotary clamping device for glass bottle processing.

[0006] This utility model is achieved through the following technical solution:

[0007] A rotary clamping device for glass bottle processing includes a support frame, a support shaft, and a support cylinder. The support cylinder and the support shaft are threaded together. A first rotating component is connected to the support frame and rotatably mounted on the support cylinder. Several sets of first connecting arms and second connecting arms are rotatably connected in a circular array on the side of the support cylinder. The first connecting arms and second connecting arms are correspondingly arranged in the length direction of the support shaft. A pressing arm is rotatably connected between the ends of the first connecting arms and second connecting arms away from the support cylinder. The support cylinder, the first connecting arms, the pressing arm, and the second connecting arm form a parallelogram four-bar linkage mechanism. A pressing plate is provided on the outer side of the pressing arm to press and position the inner wall of the glass bottle. A second rotating component is rotatably mounted on the support shaft. A push-pull rod rotatably connected to the second rotating component and rotatably connected to the first connecting arm is rotatably mounted on the second rotating component.

[0008] A further improvement of this utility model is that the outer side of the pressing plate is covered with a pressing pad, and the outer side of the pressing pad has an arc-shaped structure that fits the inner wall of the glass bottle.

[0009] A further improvement of this utility model is that the first rotating component adopts a bearing structure.

[0010] A further improvement of this invention is that the second rotating component adopts a bearing structure.

[0011] A further improvement of this utility model is that a nut that can abut against the support cylinder is screwed onto the support shaft.

[0012] A further improvement of this utility model is that an operating rod is connected and installed on the support cylinder, and a rotating force-applying part is provided on the support shaft.

[0013] A further improvement of this utility model is that the rotational force-applying part is an insertion hole that passes through the support shaft.

[0014] A further improvement of this utility model is that the rotational force-applying part is a clamping part provided at the end of the support shaft.

[0015] A further improvement of this utility model is that the support cylinder is provided with an outwardly protruding first connecting seat and a second connecting seat, the first connecting seat being rotatably connected to the first connecting arm, and the second connecting seat being rotatably connected to the second connecting arm.

[0016] A further improvement of this utility model is that the first connecting seat has a plurality of adjustment holes spaced apart in an arc shape, and the axis of rotation of the second connecting arm and the second connecting seat passes through the center of the arc where the adjustment holes are located; the adjustment holes can be rotatably connected and installed with the first connecting arm.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] In use, the pressing arms are positioned close to the support shaft. A cylindrical glass bottle with its mouth facing down is fitted onto the outside of the device. The support shaft is rotated relative to the support cylinder, causing the second rotating component to move downwards. The push-pull rod pushes the first connecting arm, causing the pressing arms in the parallelogram four-bar linkage structure to unfold outwards until all the pressing plates are pressed against the inner wall of the glass bottle, thus achieving reliable and stable clamping of the glass bottle. Rotating the support cylinder relative to the support frame enables the rotation of the clamped glass bottle, allowing for processing of the outer wall of the glass bottle, such as frosting, labeling, and painting, improving processing quality and efficiency. This rotary clamping device for glass bottle processing forms a parallelogram four-bar linkage with a support cylinder, a first connecting arm, a pressing arm, and a second connecting arm. This allows for flexible adjustment of the inner and outer positions of the pressing arm, enabling flexible clamping of glass bottles with different inner diameters, improving versatility, and effectively saving on the development cost of clamping equipment. Furthermore, the multi-ring array structure effectively ensures uniform distribution of the pressing force on the inner wall of cylindrical glass bottles, improving clamping stability. The pressing plate positions the inner wall of the glass bottle by compression, avoiding interference problems caused by traditional clamping of the outer wall during processing such as sanding, labeling, and painting. The overall structure is simple, foldable, and retractable, offering excellent practicality. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figure 1-3 As shown, this utility model discloses a rotary clamping device for glass bottle processing, including a horizontal support frame 1, a vertical support shaft 4, and a vertical support cylinder 3. The support frame 1 is fixedly connected to an external mounting frame. The support shaft 4 has a threaded section in the middle that is threaded to the support cylinder 3. The length of the threaded section is greater than the length of the support cylinder 3 to facilitate reliable rotational adjustment. A first rotating component 2 is fixedly connected to the support frame 1 and rotates to fit on the outer side of the bottom of the support cylinder 3 (the first rotating component 2 cannot move in the axial direction of the support cylinder 3). Several sets (at least three sets) of first connecting arms 7 and second connecting arms 8 are rotatably connected in a circular array on the side of the support cylinder 3. The first connecting arms 7 and second connecting arms 8 are correspondingly arranged vertically along the length (vertical) of the support shaft 4. Arm 8 is horizontally aligned with the rotation axis of the support cylinder 3 and perpendicular to the second rotating component 5, and is positioned vertically and vertically (two rotation axes); a pressing arm 9 is rotatably connected between the ends of the first connecting arm 7 and the second connecting arm 8 away from the support cylinder 3, and the support cylinder 3, the first connecting arm 7, the pressing arm 9, and the second connecting arm 8 form a parallelogram four-bar linkage mechanism; a pressing plate 91 capable of pressing and positioning the inner wall of the glass bottle is connected to the outer side of the pressing arm 9; a second rotating component 5 is rotatably mounted on the upper end of the support shaft 4 (the second rotating component 5 cannot move in the axial direction of the support shaft 4), and a push-pull rod 6 rotatably connected to the second rotating component 5 and rotatably connected to the first connecting arm 7, the rotation axes at both ends of the push-pull rod 6 are horizontal and perpendicular to the length direction of the support shaft 4 respectively.

[0026] In use, the pressing arm 9 is positioned close to the support shaft 4. The cylindrical glass bottle is fitted onto the outside of the device with its mouth facing down. The support shaft 4 is rotated relative to the support cylinder 3, causing the second rotating component 5 to move downward relative to the support cylinder 3. The push-pull rod 6 pushes the first connecting arm 7, causing the pressing arm 9 in the parallelogram four-bar structure to unfold outward (always remaining upright) until all the pressing plates 91 are pressed against the inner wall of the glass bottle, thus achieving reliable and stable clamping of the glass bottle. The support cylinder 3 can be rotated relative to the support frame 1 (via the first rotating component 2) to achieve the rotational action of clamping the glass bottle, thereby enabling the processing of the outer wall of the glass bottle, such as frosting, labeling, and painting, improving processing quality and efficiency. This rotary clamping device for glass bottle processing forms a parallelogram four-bar linkage with the support cylinder 3, the first connecting arm 7, the pressing arm 9, and the second connecting arm 8. This allows for flexible adjustment of the inner and outer positions of the pressing arm 9, enabling flexible clamping of glass bottles with different inner diameters, improving versatility, and effectively saving on the development cost of the clamping device. Furthermore, the multi-ring array structure effectively ensures the uniformity of the pressing force distribution on the inner wall of the cylindrical glass bottle, improving clamping stability. The pressing plate 91 positions the inner wall of the glass bottle by compression, avoiding interference problems caused by traditional clamping of the outer wall during processing such as sanding, labeling, and painting. The overall structure is simple and foldable (after processing or when storage is required, the support shaft 4 rotates in the opposite direction relative to the support cylinder 3, and the pressing arm 9 moves closer to the support shaft 4), making it highly practical.

[0027] Among them, the upper end of the support shaft 4 and the upper side of the first connecting arm 7 are covered with a rubber protective layer to improve the protection of the inner wall of the glass bottle and avoid scratches.

[0028] In one embodiment, both the first rotating component 2 and the second rotating component 5 employ a bearing structure; the inner ring of the first rotating component 2 is fixedly fitted to the support cylinder 3, and the outer ring is connected to the support frame 1; the inner ring of the second rotating component 5 is fixedly fitted to the support shaft 4. This effectively achieves smooth and precise rotational movement, greatly reduces rotational friction resistance, and enhances ease of use.

[0029] In another embodiment, the first rotating member 2 and the second rotating member 5 adopt a sliding sleeve structure, and the support cylinder 3 and the support shaft 4 are provided with annular grooves that limit the axial movement of the sliding sleeve. The structure is simple and easy to implement.

[0030] The pressing plate 91 is covered with a rubber (with a certain degree of elasticity) pressing pad 92 on its outer side. The outer side of the pressing pad 92 has an arc-shaped structure that fits into the inner wall of the glass bottle. The pressing pad 92 is a removable adsorption (adhesive or magnetic) type, which can be easily replaced and adapted to different glass bottles. This avoids the pressing plate 91 directly contacting the inner wall of the glass bottle, thus preventing scratches, wear, and other damage to the glass bottle. It also increases the friction with the inner wall of the glass bottle, making the glass bottle more stable when clamped and less prone to slippage. This further improves the reliability of clamping and ensures that the glass bottle remains in a fixed position during rotation processing.

[0031] The lower end of the threaded section of the support shaft 4 is screwed with a nut 11 that abuts against the lower part of the support cylinder 3. By rotating the nut 11 to abut against the lower part of the support cylinder 3, axial movement of the support cylinder 3 due to vibration, rotation, or other factors is effectively prevented, ensuring the reliability of the glass bottle clamping, preventing the glass bottle from shaking or falling, and thus ensuring the processing quality of the glass bottle.

[0032] The support cylinder 3 is detachably equipped with an operating lever 10, and the support shaft 4 is provided with a rotational force-applying part. The support cylinder 3 can be fixed by holding the operating lever 10, and the rotational force-applying part can be rotated relative to the support cylinder 3 by rotating it. After the glass bottle is clamped, the glass bottle can also be rotated by moving the operating lever 10.

[0033] In one embodiment, the rotational force-applying part is an insertion hole 41 that passes through the support shaft 4. By inserting a rod into the insertion hole 41 and rotating the rod, the rotation of the support shaft 4 relative to the support cylinder 3 can be adjusted. In addition, after the glass bottle is clamped, the glass bottle can also be rotated by moving the rod.

[0034] In another embodiment, the rotational force-applying part is a clamping part 42 located at the lower end of the support shaft 4. The clamping part 42 has a square or regular hexagonal cross-section, and its center is located on the axis of the support shaft 4. By clamping and rotating the clamping part 42 with a wrench, or by connecting the motor output end to the clamping part 42 through a connecting sleeve, the rotation adjustment of the support shaft 4 relative to the support cylinder 3 can be realized. In addition, after the glass bottle is clamped, the clamping part 42 can also be driven to rotate to realize the rotation of the glass bottle.

[0035] The support cylinder 3 is provided with an outwardly protruding first connecting seat 31 and a second connecting seat 32. The first connecting seat 31 is rotatably connected to the first connecting arm 7, and the second connecting seat 32 is rotatably connected to the second connecting arm 8. This facilitates the rotatable connection of the first connecting arm 7 and the second connecting arm 8, and allows for a large range of rotation of the first connecting arm 7 and the second connecting arm 8.

[0036] Furthermore, the first connecting seat 31 has several adjustment holes spaced out in an arc shape. The axis of rotation of the second connecting arm 8 and the second connecting seat 32 passes through the center of the arc where the adjustment holes are located. The adjustment holes can be rotatably connected to the first connecting arm 7. By rotatably connecting the first connecting arm 7 to different adjustment holes, the tilt angle of the pressing arm 9 can be adjusted, thus adapting to glass bottles of different shapes (with a certain tilt angle on the inner wall), and improving versatility.

[0037] This rotary clamping device for glass bottle processing operates by positioning the pressing arm 9 close to the support shaft 4. A cylindrical glass bottle with its mouth facing downwards is fitted onto the outside of the device. The support shaft 4 rotates relative to the support cylinder 3, causing the second rotating component 5 to move downwards relative to the support cylinder 3. The push-pull rod 6 pushes the first connecting arm 7, causing the pressing arm 9 in the parallelogram four-bar linkage structure to unfold outwards (always remaining vertical) until all the pressing plates 91 are pressed against the inner wall of the glass bottle, thus achieving reliable and stable clamping of the glass bottle. Rotating the support cylinder 3 relative to the support frame 1 (via the first rotating component 2) enables the rotational action of the clamped glass bottle, allowing for processing of the outer wall of the glass bottle, such as frosting, labeling, and painting, improving processing quality and efficiency. This rotary clamping device for glass bottle processing forms a parallelogram four-bar linkage with the support cylinder 3, the first connecting arm 7, the pressing arm 9, and the second connecting arm 8. This allows for flexible adjustment of the inner and outer positions of the pressing arm 9, enabling flexible clamping of glass bottles with different inner diameters, improving versatility, and effectively saving on the development cost of the clamping device. Furthermore, the multi-ring array structure effectively ensures the uniformity of the pressing force distribution on the inner wall of the cylindrical glass bottle, improving clamping stability. The pressing plate 91 positions the inner wall of the glass bottle by compression, avoiding interference problems caused by traditional clamping of the outer wall during processing such as sanding, labeling, and painting. The overall structure is simple and foldable (after processing or when storage is required, the support shaft 4 rotates in the opposite direction relative to the support cylinder 3, and the pressing arm 9 moves closer to the support shaft 4), making it highly practical.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
