Description

Technical Field

[0001] This utility model relates to the field of liquid packaging machines, specifically to a bottle protection adjustment structure for a liquid packaging machine. Background Technology

[0002] In liquid packaging machinery, filling machines are typically used to automatically fill liquid products such as beverages and liquid foods into containers such as bottles or cans. In order to realize the transfer of bottles between different processes, the filling machine is equipped with a star wheel transmission mechanism. The star wheel pushes the bottle neck and bottle body onto the filling machine. On the outside of the star wheel, a protective plate and other bottle protection components are installed. These components are supported by support accessories such as columns and brackets to protect and guide the bottles, prevent the bottles from swinging, and enable the star wheel to transfer the bottles stably.

[0003] However, with the increasing demand for diversified products, a single filling machine often needs to produce multiple bottle types simultaneously to meet the needs of more bottle production. However, the existing bottle protection components on filling machines can only adapt to a single bottle type. When filling different bottle types, the bottle protection components need to be manually disassembled and replaced with suitable components. These components are often large, and each replacement requires adjustments to the bottle gap, resulting in a time-consuming disassembly and installation process, leading to a heavy workload, inconvenience, and a significant impact on production efficiency. Furthermore, these bottle protection components are often limited to a few pre-set support parts, limiting the bottle types they can adapt to. It is difficult to make more precise adjustments to the bottle gap between the bottle protection component and the star wheel. If these support parts deform or deviate from their preset positions during processing, or if there are significant errors in bottle size, the original structure will be unable to adapt to the corresponding bottle specifications, requiring complete remanufacturing, which further increases production costs. Utility Model Content

[0004] The purpose of this invention is to overcome the problems existing in the prior art and provide a bottle protection adjustment structure for liquid packaging machines that can easily adjust the gap between the bottle protection component and the star wheel to adapt to different bottle sizes, thereby improving production efficiency.

[0005] The bottle protection adjustment structure of the liquid packaging machine of this utility model includes a base plate and a bottle protection assembly located above the base plate. The bottle protection assembly is fixed to the base plate by a support column. An adjustment assembly is also provided between the bottle protection assembly and the support column. The adjustment assembly includes a fixed plate rotatably disposed at the top of the support column and a sliding sleeve adapted to be disposed above the fixed plate. The top of the support column and the fixed plate are provided with mutually cooperating first screw holes. A first screw passes through the first screw hole, so that the fixed plate can be detachably installed at the top of the support column and can rotate around the support column to adjust its position. The fixed plate is provided with second screw holes on both sides. The upper part of the sliding sleeve is fixedly connected to the bottle protection assembly. The sliding sleeve is provided with sliding grooves on both sides corresponding to the second screw holes. A second screw passes through the sliding groove and is threaded into the second screw hole, so that the sliding sleeve can be detachably installed on the fixed plate and can slide along the fixed plate to change the position of the sliding sleeve relative to the fixed plate.

[0006] As a further preferred embodiment of the present invention, the bottle protection assembly includes a plurality of parallel and spaced-apart protective plates, and a connecting rod passing through the protective plates. The outer side of each protective plate abuts against the side wall of the bottle, and the bottom end of the connecting rod is fixedly connected to the sliding sleeve.

[0007] As a further preferred embodiment of this utility model, each protective plate is an arc-shaped protective plate.

[0008] As a further preferred embodiment of this utility model, a hand-held part is provided at the top of the connecting rod.

[0009] As a further preferred embodiment of this utility model, a gasket is provided between the guard plate and the connecting rod.

[0010] As a further preferred embodiment of this utility model, a scale is marked on the surface of the fixing plate.

[0011] The bottle protection adjustment structure of the liquid packaging machine of this utility model features a fixed plate rotatably mounted on the top of a support column. A first screw secures the fixed plate detachably to the support column. A sliding sleeve, which can slide relative to the fixed plate, is fitted onto the fixed plate and secured detachably to the fixed plate using a second screw. When adjusting the distance between the bottle protection assembly and the star wheel, loosening the first screw allows the fixed plate to rotate around the support column to adjust its position. Loosening the second screw allows the sliding sleeve to slide along the fixed plate to change its position relative to the fixed plate. Through the interaction of the fixed plate and the sliding sleeve, the position of the upper bottle protection assembly relative to the star wheel can be gradually changed, achieving stepless adjustment to accommodate bottles of different sizes and ensuring that the bottle protection assembly effectively abuts against the bottle. After adjusting the bottle protector assembly to the desired position, tighten the first and second screws to fix the fixing plate and sliding sleeve, thus completing the position adjustment of the bottle protector assembly. The operation is convenient and does not require disassembly and reassembly of the entire bottle protector assembly structure. This allows for adjustment of the bottle protector assembly position as needed, enabling compatibility with more bottle sizes, meeting more production demands, and improving production efficiency. Furthermore, when the support column deviates from the preset position due to processing errors or when there are significant errors in the bottle size, stepless adjustment can be achieved through the fixing plate and sliding sleeve. This allows for convenient adjustment of the radial or circumferential position of the bottle protector assembly, effectively correcting and compensating for the aforementioned errors. It eliminates the need to replace and remake the entire star wheel transmission mechanism due to insufficient precision, helping to save production costs. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

If the specific posture changes, the directional indication will also change accordingly.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical features of each embodiment can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described; however, as long as these combinations of technical features do not contradict each other, they should all be considered within the scope of this specification.

[0026] like Figures 1 to 9 As shown, the bottle protection adjustment structure of the liquid packaging machine in this embodiment includes a base plate 1 and a bottle protection assembly 2 located above the base plate 1. The bottle protection assembly 2 is fixed to the base plate 1 by a support column 3, which provides support for the bottle protection assembly 2. The bottle protection assembly 2 abuts against the side wall of the bottle 7, providing protection and guidance for the bottle. An adjustment assembly is also provided between the bottle protection assembly 2 and the support column 3. The adjustment assembly includes a fixed plate 4 rotatably mounted on the top of the support column 3 and a sliding sleeve 5 adapted to be mounted on the fixed plate 4. Corresponding features are provided on the top of the support column 3 and the fixed plate 4. The first screw hole 41 is mutually fitted, and the first screw 42 is inserted into the first screw hole 41, so that the fixing plate 4 can be detachably installed on the top of the support column 3 and can rotate around the support column 3 to adjust its position. The fixing plate 4 has second screw holes 43 on both sides. The upper part of the sliding sleeve 5 is fixedly connected to the bottle protection assembly 2. The sliding sleeve 5 has sliding grooves 51 on both sides corresponding to the second screw holes 43. The second screw 44 passes through the sliding grooves 51 and is threaded into the second screw hole 43, so that the sliding sleeve 5 can be detachably installed on the fixing plate 4 and can slide along the fixing plate 4 to change the position of the sliding sleeve 5 relative to the fixing plate 4.

[0027] In the above structure, a fixing plate 4 is rotatably installed on the top of the support column 3, and a first screw 42 is inserted into the first screw hole 41. The first screw 42 is tightened so that its nut part presses against the fixing plate, thereby detachably locking the fixing plate 4 above the support column 3. When it is necessary to rotate the fixing plate, simply loosen the first screw so that the fixing plate can rotate above the support column, thereby changing the relative position between the fixing plate and the support column. After adjusting to the desired position, tighten the first screw again to lock the fixing plate onto the support column. A sliding sleeve 5 is fitted onto the fixed plate 4, allowing it to slide relative to the fixed plate 4. The sliding grooves 51 on both sides of the sliding sleeve 5 cover the second screw holes 43 on both sides of the fixed plate. A second screw 44 passes through the sliding groove 51 of the sliding sleeve and is threaded into the second screw hole 43. The nut portion of the second screw 44 presses the two sides of the sliding sleeve together, allowing the sliding sleeve 5 to be detachably locked onto the fixed plate 4. When it is necessary to move the sliding sleeve, simply loosen the second screw. The nut portion will no longer press the sliding sleeve, and the second screw will be limited by the elongated sliding groove, allowing it to move within the length of the groove. The sliding sleeve remains fitted onto the fixed plate and can slide along the fixed plate, changing the relative position between the sliding sleeve and the fixed plate. After adjusting to the desired position, tighten the second screw again, causing the nut portion of the second screw to press the two sides of the sliding sleeve again, locking the sliding sleeve securely onto the fixed plate. When installing the sliding sleeve onto the fixed plate, the second screw can be used to lock and fix it on both sides, or only on one side. Figure 6 As shown, the number of second screw holes 43 on the two sides of the fixing plate 4 can be set to two or more to accommodate the length of the fixing plate and the sliding sleeve, ensuring that the sliding sleeve can be adjusted to the required position. During installation, the sliding sleeve can be fitted onto the fixing plate at the appropriate position.

[0028] When it is necessary to adjust the bottle spacing between the bottle protection assembly and the inlet star wheel 6, the adjustment components on each support column are unlocked by loosening the first and second screws. This allows the fixing plate to rotate relative to the support column, and the sliding sleeve to slide on the fixing plate. Through the cooperation of the fixing plate and the sliding sleeve, the position of the bottle protection assembly in the radial or circumferential direction is adjusted. This effectively addresses situations where the support column or other support components deviate from their preset position due to deformation or errors during processing, or where there are significant errors in the bottle dimensions, resulting in the bottle spacing between the bottle protection assembly and the inlet star wheel not matching the bottle specifications. This ensures that when... Even under the aforementioned error conditions, the bottle protection assembly can still fine-tune the spacing, achieving stepless adjustment. This provides stable protection and guidance for the bottles, preventing them from swinging and ensuring that the bottle feeding star wheel can stably transport the bottles. Therefore, there is no need to replace or remake the entire star wheel transmission mechanism due to insufficient precision, which helps save production costs. During the above adjustment process, there is no need to disassemble and reassemble the entire bottle protection assembly structure, making it more convenient to operate. The position of the bottle protection assembly can be adjusted at any time according to actual needs, thereby achieving the function of quickly switching to be compatible with more bottle sizes, saving time, improving production efficiency, and meeting more production needs.

[0029] The bottle protection assembly 2 is supported by a support column 3. A first screw hole is provided at the top of the support column, which is then fixed to the fixing plate below the bottle protection assembly using a first screw. The bottom end of the support column can be directly fixed to the base plate 1 by welding, or... Figure 3 As shown, mounting holes 11 are provided on the base plate 1, allowing the bottom end of the support column 3 to pass through the mounting holes 11 and be fixed by a detachable method such as threaded connection. This allows the support column 3 to be removed from the base plate 1, further reducing the space occupied after disassembly. Multiple sets of mounting holes 11 can be provided on the base plate 1, with each set of holes spaced radially along the bottle inlet star wheel and corresponding to different bottle spacing levels. This eliminates the need for large-sized adjustment components, ensuring the stability of the bottle protection assembly. By installing the support column in the mounting holes corresponding to the bottle spacing, the bottle protection assembly can be adapted to the required bottle specifications. When there are slight differences in bottle spacing or machining errors in the mounting holes, the radial position of the bottle protection assembly can be adjusted using the adjustment components on each support column to correct these errors.

[0030] The bottle protection assembly 2 includes a plurality of parallel and spaced-apart protective plates 21, and a connecting rod 22 passing through the protective plates 21. The outer side of each protective plate 21 abuts against the side wall of the bottle, and the bottom end of the connecting rod 22 is fixedly connected to the sliding sleeve 5. Specifically, the bottle protection assembly 2 can be configured as follows: Figure 9The diagram shows three protective plates 21, each with a fixing hole for the connecting rod 22 to pass through and be fixed. A third screw hole 52 is provided above the sliding sleeve 5, and a threaded section matching the third screw hole 52 is provided at the bottom end of the connecting rod 22, thus fixing the connecting rod 22 to the upper part of the sliding sleeve 5. The shape and specifications of the protective plates can be selected as needed to adapt each protective plate to the shape of the bottle and provide good protection. In this embodiment, each protective plate is set as an arc-shaped protective plate to better adapt to the curvature of the bottle and provide better clamping effect.

[0031] Furthermore, a hand-held part 23 can be provided at the top of the connecting rod 22. The hand-held part can be specifically configured as a handwheel or other device. By providing a hand-held part at the top of the connecting rod, it is more convenient for the operator to adjust the position of the bottle protection component.

[0032] A gasket 24 can be added between the protective plate 21 and the connecting rod 22 to provide a certain degree of protection, reduce the occurrence of wear and other damage caused by excessive compression of the protective plate to the connecting rod, thereby affecting the fixing effect of the protective plate and ensuring the safety and integrity of the entire bottle protection assembly.

[0033] In addition, a scale can be marked on the surface of the fixed plate 4 so that the operator can move the position of the sliding sleeve relative to the fixed plate more accurately when adjusting the bottle protection assembly.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
