Description

Technical Field

[0001] This utility model belongs to the field of mechanical testing technology, specifically relating to a device for detecting the lateral force of the capping knife in a capping assembly. Background Technology

[0002] Currently, the lateral force of the capping blade in the capping assembly is one of the important factors affecting capping quality. Precise control of this lateral force is crucial during the calibration of the capping assembly. Typically, this is measured manually using a tension gauge. However, due to differences in the operator's individual perception and subjective judgment standards, deviations are prone to occur, making it difficult to ensure consistency in the tension applied to different capping blades and the direction of the tension gauge's force. This subjectivity and inconsistency directly affect the accuracy of the data and pose potential risks to the capping effect of the product. Furthermore, when manually operating the tension gauge, it cannot be fixed in a specific position, and measurement and adjustment must be performed separately, affecting the accuracy and efficiency of the adjustment. Therefore, while manual operation is simple, it is difficult to ensure the accuracy and stability of the lateral force measurement values, and it cannot simultaneously implement rapid adjustments during measurement.

[0003] Therefore, a new technology is needed to solve the problems of inaccurate lateral force measurements and low measurement efficiency in existing technologies. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0032] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or it can be indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," and "right" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

[0033] Reference Figure 1 and Figure 4 A device for detecting the lateral force of a capping assembly's sealing knife is disclosed. Its main structure can be made of aluminum alloy, significantly reducing the device's weight and improving operational ease of use. The device includes a base and a fixing mechanism 1, a precision adjustment mechanism 2, and a tension control mechanism 3 mounted on the base. The fixing mechanism 1 includes at least two spaced fixing blocks 12 and a fixing support mounted on the base. The upper end of the fixing support has a placement groove 111 for placing the lower part of the capping assembly's base 4. One end of each fixing block 12 is detachably mounted on the fixing support. Several fixing blocks 12 are arranged around the placement groove 111, with one end detachably mounted on the fixing support and the other end detachably fixedly connected to the capping assembly's base 4. The fixing blocks 12 are used to fix the capping assembly's base 4 to the fixing support. When the capping assembly's base 4 is located within the placement groove 111, the sealing knife is located outside the placement groove 111 and above the fixing support. By tightly fixing the fixed support structure to the capping head, the lateral freedom of the entire testing device is effectively limited during the testing and adjustment process, ensuring the consistency of the tensile force direction during the test and avoiding deviations in test data caused by device shaking or offset.

[0034] The fixing bracket 12 is inverted L-shape or 7-shape, and includes a first segment 121 and a second segment 122 connected to each other in an L-shape. The first segment 121 has external threads and is detachably fixed to the fixing support. The first segment 121 can pass through the fixing support and is assembled on the fixing support with a wing nut. The base 4 of the cap assembly is located between several first segments 121, which surround the base 4 of the cap assembly. Each second segment 122 is located above the base 4 of the cap assembly and abuts against and is fixed to the upper end face of the base 4 of the cap assembly. The fixing brackets 12 are used to clamp and fix the base 4 of the cap assembly. Preferably, there are two fixing brackets 12, which are arranged opposite each other and located on opposite sides of the base 4 of the cap assembly.

[0035] The tension control mechanism 3 includes a tension gauge 31, a fixing block 33, and a screw 32. The bottom of the fixing block 33 is fixedly connected to the base. The screw 32 is horizontally positioned, with one end of the screw 32 near the fixed support detachably fixedly connected to the tension gauge 31, and the other end threadedly connected to the fixing block 33. The end of the tension gauge 31 away from the screw 32 can be connected to a capping knife. The capping knife can be connected to the tension gauge 31 via a conventional connection method. The capping knife can be connected to the tension gauge 31 via a hook. Operating the control screw 32 causes the tension gauge 31 to move axially, avoiding the influence of dynamic stress on the measurement results. It allows for easy adjustment of parameters such as test speed, significantly improving testing efficiency and convenience, and solving the problem of unstable tension output in traditional manual operation.

[0036] The precision control mechanism includes a scale plate 21, one end of which is detachably fixed to the fixed support, and the other end is detachably fixed to the fixed block 33. Displacement scale lines 214 of the tension gauge 31 are designed according to the tensile force range measured with different specifications of capping heads, ensuring precise control of the tensile force value within a unified standard, achieving standardization of maintenance operations, and greatly improving the accuracy and uniformity of test data. The number and position of each scale line 214 can be set according to actual conditions; all scale lines 214 are parallel to each other and perpendicular to the tensile length direction of the tension gauge.

[0037] Specifically, the fixed support includes a fixed sleeve 11, the upper end of which is provided with a countersunk groove for forming the placement groove 111. Each of the fixing brackets 12 is installed on the fixed sleeve 11. The upper end of the fixed sleeve is provided with fixing holes 112 corresponding to each of the fixing brackets 12. The fixing holes 112 can be through holes or threaded holes. When the fixing hole 112 is a threaded hole, the first segment 121 is screwed into the corresponding threaded hole and threadedly connected to the fixed sleeve. When the fixing hole 112 is a through hole, the first segment 121 of each fixing bracket 12 can pass through the through hole and threadedly connected to the wing nut, thereby fixing the fixed sleeve 11 to the base 4 of the cap assembly.

[0038] The function of the fixing sleeve 11 in this scheme is to fix the detection device on the base 4 of the capping assembly, so that the entire fixing support will not shake or shift during the measurement process and can maintain a stable state. The scale lines 214 on the scale plate 21 are marked and positioned according to the capping knife stroke range of different specifications of capping assemblies. After installation, the tension of the tension gauge 31 can be controlled by rotating the screw 32, which can avoid the influence of dynamic stress on the measured value and can easily and stably control the tension gauge 31 to measure parameters such as lateral force and displacement.

[0039] In use, the fixing sleeve 11 is installed on the base 4 of the capping head assembly or capping component via the fixing bracket 12. The end of the tension gauge 31 is connected to the hook of the screw 32, and the other end of the tension gauge 31 is connected to the capping knife to be tested. By operating the handle or handle 34 of the screw 32, the screw 32 is moved axially, thereby driving the tension gauge 31 to work and achieve accurate measurement.

[0040] Specifically, the precision control mechanism further includes a quantitative block 22, which has an elongated hole 221. Two 5-bolts, one end of which passes through the elongated hole 221, can be fixedly connected to the scale plate 21. The size of the nut portion of the 5-bolt is larger than the width of the elongated hole 221. The quantitative block 22 can slide horizontally relative to the 5-bolt or the scale plate 21 through the elongated hole 221. The quantitative block 22 can move horizontally relative to the scale plate 21 along the length direction of the elongated hole 221. The length direction of the elongated hole 221 is parallel to the stretching direction of the tension gauge 31. The scale plate 21 has a number of parallel and spaced scale lines 214 arranged sequentially along the length direction of the elongated hole 221. The scale lines on the scale plate 21 are marked and positioned according to the stroke range of the capping knife of different specifications of capping assemblies. After installation, the stretching of the tension gauge 31 can be controlled by rotating the screw 32. The position of each scale line 214 and the displacement value it represents can be set according to the actual situation.

[0041] In use, one end of the metering block 22 can be slidably adjusted to be flush with a certain scale line 214. After the adjustment is in place, tighten the two bolts 5 and rotate the screw 32 to control the tension of the tension gauge 31, so that the capping knife moves toward the tension control mechanism 3 until the capping knife contacts or abuts against the metering block 22. Observe the tension value displayed by the tension gauge 31, so as to determine whether the lateral force of the capping knife of the capping assembly meets the requirements based on the tension value. Alternatively, loosen the two bolts 5 to allow the metering block 22 to slide horizontally, and position the end of the metering block 22 near the capping knife in contact with the capping knife, while aligning the end of the metering block 22 away from the capping knife with a certain scale line 214. Rotate the screw 32 to control the tension of the tension gauge 31, causing the capping knife to move towards the tension control mechanism 3. The metering block 22 moves synchronously with the capping knife. When the end of the metering block 22 away from the capping knife reaches the corresponding scale line 214, observe the tension value displayed on the tension gauge 31. This allows you to determine whether the lateral force of the capping knife in the capping assembly meets the requirements. The dimensions of the metering block 22 can be designed according to actual conditions, ensuring that when the metering block is installed on the scale plate, its end aligns with the corresponding scale set according to the displacement of capping knives of different specifications. The function of the metering block 22 is to limit and unify the displacement of the capping knife and the tension gauge, ensuring the consistency of measurement data. By sliding the metering block 22 along the elongated hole 221 in the horizontal direction, uniformity in measurement of different varieties can be achieved.

[0042] Specifically, the precision adjustment mechanism 2 further includes at least two fixing components, which can be screws. These fixing components are used to detachably fix the scale plate 21 to the bottom of the fixing sleeve 11, passing through the scale plate 21. The fixing sleeve 11 has two spaced-apart threaded connection holes 113 at its lower part. One end of a screw passes through the scale plate and is threaded into the corresponding threaded connection hole 113 at the lower part of the fixing sleeve 11. All fixing components are located below the recess. Two screws with identical structures can be selected to connect and fix the scale plate 21 to the fixing sleeve 11. The horizontal cross-section of the upper part of the fixing sleeve 11 can be concave to form a placement groove 111.

[0043] Specifically, the scale plate 21 is T-shaped, and a first connecting portion 212 and a second connecting portion 213 are respectively protruding on both sides of the end of the scale plate 21 near the fixed sleeve 11. The two fixing members 23 pass through the first connecting portion 212 and the second connecting portion 213 respectively and are threadedly connected to the fixed sleeve 11. The elongated hole 211 is located between the first connecting portion 212 and the second connecting portion 213.

[0044] Specifically, the scale plate 21 is located below the screw 32 and the force gauge 31 and is parallel to the screw 32 and the force gauge 31.

[0045] Specifically, the tension control mechanism 3 further includes a handle 34, which is perpendicular to the screw 32 and detachably fixed to the screw 32. The handle 34 is located on the side of the fixing block 33 away from the fixing sleeve 11.

[0046] Specifically, the screw 32 is provided with a connecting hole, the axis of the connecting hole is perpendicular to the axis of the screw 32, and the handle 34 can pass through the connecting hole and its two ends protrude from the two ends of the connecting hole respectively.

[0047] This testing device enables the detection of lateral force on the capping blade of the capping assembly. Addressing the shortcomings of traditional manual tensile testing techniques, it represents a significant technological advancement and improved efficiency. The design of the fixing mechanism 1 effectively restricts lateral freedom during the testing process. Preliminary experimental data shows that compared to traditional manual methods, it significantly improves work efficiency and the accuracy of test results, effectively ensuring consistency in tensile force measurement and adjustment, and reducing human error. The precision control mechanism 2's quantitative block 22 and the preset tensile length range of the tensile gauge 31 enable precise detection of tensile force values ​​for capping heads of different specifications, effectively improving the accuracy of the device's test results and achieving precise control. This testing device is adaptable to different models of capping heads for tensile testing, meeting diverse product needs and effectively improving work efficiency. Standardized maintenance and testing procedures can be set according to actual conditions, reducing interference from human factors, improving work efficiency, and minimizing problems such as impacts on production efficiency and quality control caused by improper operation, thus achieving standardized operations. Product Quality Improvement: The testing device in this solution, through the aforementioned structural design, ensures stable capping quality, reduces capping problems caused by lateral force on the roller cutter arm, lowers wine loss in bottled wine, and improves production quality and brand image. In the long term, this device can significantly optimize the problems of high defective product quantity and significant wine loss caused by capping quality issues, improve production efficiency, and reduce maintenance costs, achieving the goal of cost reduction and efficiency improvement, and realizing cost savings. Furthermore, the capping component sealing blade lateral force testing device in this solution has already been put into use for parameter testing and adjustment of capping components for 970ml, 980ml, and 707ml bottle types.
