Description

Technical Field

[0001] This application relates to the field of torque testing instruments, and more particularly to a bottle cap torque meter. Background Technology

[0002] Bottle packaging is a common form of packaging for food, beverages, and pharmaceuticals. The torque value for locking and opening bottle caps is one of the key process parameters that production units control offline or online. Whether the torque value is appropriate has a significant impact on product transportation and final consumption. It is one of the key product indicators that enterprises control. To test the torque value, some bottle cap torque testing devices have appeared on the market.

[0003] In existing technologies, such as the "manual torque meter" proposed in Chinese patent CN209280184 U, a housing, torque sensor, connecting cylinder, square-head connector, turntable, and clamping assembly are included. The upper front of the housing has an inclined surface, on which a display screen connected to the torque sensor is mounted. A labyrinth-sealed structure is formed by the mounting plate of the connecting cylinder and the waterproof groove of the turntable. This torque meter effectively prevents liquid from splashing or spilling into the testing instrument during testing, ensuring normal operation and extending its service life.

[0004] However, the torque meter mentioned above, when manually rotating the bottle cap for testing, will exhibit lateral deviation due to the force applied, resulting in inaccurate test results. Furthermore, the clamping component of the torque meter has a small contact area with the bottle body, making it easy to deform and damage the bottle body when clamping it. Utility Model Content

[0005] This application provides a bottle cap torque meter that can prevent the bottle cap from shifting during rotation, improve the accuracy of the detection results, and prevent damage to the bottle body when clamping and fixing bottles of various shapes.

The fixing part is located below the clamping part and includes a linear drive device, a first clamping bladder, and a second clamping bladder. The linear drive device is connected to the first clamping bladder, and the bottle body adapted to the bottle cap is located between the first clamping bladder and the second clamping bladder. Both the first clamping bladder and the second clamping bladder are in a full state. The detector is located below the fixing part to detect the intensity of the torque.

One end of the rotating rod is fixedly connected to the clamping member, and the other end passes through the inside of the rotating shaft and is rotatably connected to the bracket. The axis of the rotating rod coincides with the axis of the rotating shaft. The two rotating shafts are centrally symmetrically arranged relative to the rotating shaft, and the two fasteners are centrally symmetrically arranged relative to the rotating shaft. The surfaces of the fasteners near the arc-shaped clamping plates are inclined so that when the rotating shaft rotates, at least a portion of the two fasteners can be simultaneously located between the inner side wall of the clamping member and the arc-shaped clamping plates. The outer wall of the clamping member is provided with a limiting part, and the rotating body... The outer wall is provided with a mating part so that the rotating body can rotate the clamping part when the limiting part and the mating part are engaged; a compression bladder is provided between the inner side wall of the clamping part and the arc-shaped clamping plate.

[0018] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Please see Figures 1 to 5 This application discloses a bottle cap torque meter, including a mounting frame 1, a rotating part, a clamping part, a fixing part, and a detector 13. The rotating part is rotatably connected to the top of the mounting frame 1, and the clamping part is connected to the rotating part so as to clamp the bottle cap when the rotating part rotates and to cooperate with the rotating part to rotate the bottle cap. The fixing part is located below the clamping part and includes a linear drive device 8, a first clamping bladder 11, and a second clamping bladder 10. The linear drive device 8 is connected to the first clamping bladder 11, and the bottle body adapted to the bottle cap is located between the first clamping bladder 11 and the second clamping bladder 10, and both the first clamping bladder 11 and the second clamping bladder 10 are in a full state. The detector 13 is located below the fixing part to detect the intensity of the torque.

[0021] Please refer to the embodiments provided in this application. Figure 1 When it is necessary to rotate the bottle cap, the bottle can be placed between the first clamping pouch 11 and the second clamping pouch 10, with the bottle abutting against the second clamping pouch 10. Then, the linear drive device 8 will push the first clamping pouch 11 towards the second clamping pouch 10. After the first clamping pouch 11 abuts against the bottle, as the linear drive device 8 continues to push the first clamping pouch 11, the first clamping pouch 11 and the second clamping pouch 10 will be squeezed and deformed and pressed against the bottle body. After deformation, both can adapt to the shape of the bottle body and increase the contact area with the bottle body, thereby improving the stability of the bottle clamping, improving the effect of clamping and fixing the bottle body, avoiding damage to the bottle body, and also clamping and fixing more bottle body shapes. By rotating the rotating part, the rotation of the rotating part can cause the clamping part to clamp the bottle cap. With the cooperation of the rotating part and the clamping part, the clamping part can make the bottle cap rotate relative to its bottle body, and the detector 13 can detect its torque intensity. When the bottle cap is manually touched and forcefully rotated, it can prevent the bottle cap from shifting to the side, thus reducing the detection error of the detector 13. After the bottle cap is clamped by the clamping part, the rotating part can continue to rotate, allowing the bottle cap to rotate relative to the bottle body it is fitted with. The linear drive device 8 includes an electric push rod.

[0022] In some embodiments of this application, please refer to Figures 2 to 4The rotating part includes a rotating shaft 3 and a rotating body 6 connected to each other. The rotating shaft 3 is rotatably mounted on the top of the mounting frame 1. The rotating body 6 has two fasteners 61 on its surface near the clamping part. The clamping part includes a clamping member 7, two arc-shaped clamping plates 71, an elastic member, and a rotating rod 5. The ends of the two arc-shaped clamping plates 71 are each provided with a rotating shaft 3, and the two rotating shafts 3 are rotatably connected to the inner bottom wall of the clamping member 7. The inner side wall of the clamping member 7 and the arc-shaped clamping plates 71 are connected to each other through a first elastic member. The top of the mounting frame 1 is provided with a bracket 2, and the bracket 2 is provided with a stop part to limit the rotating rod 5. One end of the rotating rod 5 is fixedly connected to the clamping member 7, and the other end passes through the interior of the rotating shaft 3 and is rotatably connected to the bracket 2. The axis of the rotating rod 5 coincides with the axis of the rotating shaft 3. Two rotating shafts 3 are arranged symmetrically with respect to each other, and two fasteners 61 are also arranged symmetrically with respect to the rotating shafts 3. The surfaces of the fasteners 61 near the arc-shaped clamping plate 71 are inclined so that when the rotating shafts 3 rotate, at least a portion of the two fasteners 61 can be simultaneously located between the inner wall of the clamping member 7 and the arc-shaped clamping plate 71. The outer wall of the clamping member 7 is provided with a limiting part, and the outer wall of the rotating body 6 is provided with a mating part, so that when the limiting part and the mating part are engaged, the rotating body 6 can cause the clamping member 7 to rotate.

[0023] When it is necessary to rotate the bottle cap relative to the bottle body, the rotation of the rotating rod 5 can be restricted by the stop part first, and the engagement of the mating part and the limiting part can be released. Rotating the rotating shaft 3 will cause the rotating body 6 to rotate. The fastener 61 of the rotating body 6 will gradually enter between the inner wall of the arc-shaped clamping plate 71 and the clamping member 7. As the fastener 61 enters, the cross-section of the fastener 61 will gradually increase. Then, the fastener 61 will push the two arc-shaped clamping plates 71 to rotate around their own rotating shaft 3 and move closer to each other. The process of the two arc-shaped clamping plates 71 abutting against the bottle cap and then moving closer to each other will clamp the bottle cap. The bottle cap is located between the two arc-shaped clamping plates 71. After the bottle cap is clamped and fixed, the restriction of the rotating rod 5 by the stop part is released, and the mating part and the limiting part are engaged. Then, the rotating shaft 3 is rotated again, causing the rotating body 6 to rotate. As the rotating body 6 continues to rotate, the clamping part and the rotating rod 5 will rotate, thereby causing the bottle cap to rotate relative to the bottle body.

[0024] To ensure a tighter and more stable clamping of the bottle cap by the two curved clamps 71, in some embodiments of this application, a compression bladder 14 is provided between the inner wall of the clamping member 7 and the curved clamps 71. The compression bladder 14 is made of an elastic material and is in a fully inflated state.

[0025] When the fastener 61 enters between the inner wall of the clamping member 7 and the arc-shaped clamping plate 71, the fastener 61 pushes the compression bladder 14. The compression bladder 14 deforms after being pushed, and this deformation compresses the arc-shaped clamping plate 71. Since the arc-shaped clamping plate 71 can rotate around the rotation axis 3, the compression bladder 14 brings the two arc-shaped clamping plates 71 closer together. The compression bladder 14, in conjunction with the fastener 61, allows the two arc-shaped clamping plates 71 to clamp the bottle cap more tightly. The compression bladder 14 allows the arc-shaped clamping plates 71 to clamp the bottle cap with only a small rotation angle of the rotation axis 3. Furthermore, the bottle cap can be clamped even with a reduced size of the fastener 61. A smaller fastener 61 can cooperate with a longer arc-shaped clamping plate 71 and a longer compression bladder 14. The longer arc-shaped clamping plate 71 can contact more of the outer peripheral wall of the bottle cap, thereby improving the clamping stability of the bottle cap. Understandably, rubber pads 711 can be placed on the surfaces of the two curved clamps 71 that are close to each other to further improve the clamping effect on the bottle cap.

[0026] In order to facilitate the fastener 61 to enter between the inner wall of the arc-shaped clamping plate 71 and the clamping member 7, in some embodiments of this application, the fastener 61 is provided with a plurality of balls on the surface near the arc-shaped clamping plate 71.

[0027] The ball bearings can convert the sliding friction between the fastener 61 and the arc-shaped clamp 71 into rolling friction, reducing the frictional resistance between the fastener 61 and the arc-shaped clamp 71 and facilitating the movement of the fastener 61.

[0028] In some embodiments of this application, the mating part includes a plurality of protrusions 62, which are spaced apart along the circumference of the rotating body 6. The limiting part includes a mounting block 15, a locking block 16, and a second elastic member. The mounting block 15 is fixed to the outer wall of the clamping member 7 and has a sliding groove. The locking block 16 is slidably connected to the sliding groove. The two ends of the second elastic member are respectively connected to the outer wall of the clamping member 7 and the locking block 16, so that the locking block 16 can at least partially be located between two adjacent protrusions 62.

[0029] When the mating part and the limiting part need to engage, pull the locking block 16 outward to disengage it from the two adjacent protrusions 62, thereby releasing the engagement. When the locking block 16 moves outward, it stretches the second elastic element. When the mating part needs to engage with the limiting part, release the locking block 16. Under the elastic force of the second elastic element, the locking block 16 slides towards the protrusions 62, eventually sliding between the two adjacent protrusions 62. By providing the mounting block 15 and the locking block 16 on the outer wall of the clamping member 7, and the protrusions 62 on the outer wall of the rotating body 6, the rotating body 6 can be easily adjusted to ensure that the locking block 16 corresponds to the two adjacent protrusions 62.

[0030] To ensure that the locking block 16 remains detached from the two adjacent protrusions 62 without requiring continuous manual pulling, thus reducing the operator's workload, please refer to some embodiments of this application. Figure 5 The locking block 16 includes a limiting block 162 and a sliding block 161. The sliding block 161 is connected to the second elastic member and slidably connected to the slide groove. One end of the limiting block 162 is rotatably connected to the end of the sliding block 161 away from the outer wall of the clamping member 7.

[0031] When the locking block 16 is to be disengaged from the two protrusions 62, pull the limiting block 162 to pull it out of the slide groove, then rotate the limiting block 162, and finally release the limiting block 162. The limiting block 162 and the sliding block 161 will move toward the clamping member 7 under the action of the second elastic member. During the movement, the limiting block 162 will be blocked by the groove wall at the end of the slide groove, thus keeping the limiting block 162 outside the slide groove and keeping the limiting block 162 disengaged from the two adjacent protrusions 62.

[0032] In some embodiments of this application, the stop part includes a slide block 18 and a plug rod 181 connected to each other. The rotating rod 5 is provided with a limiting hole corresponding to the plug rod 181. The slide block 18 is slidably connected to the bracket 2 so that the plug rod 181 can be inserted into the limiting hole when the slide block 18 slides.

[0033] When it is necessary to limit the rotating rod 5 of the stop part, the slide block 18 can be slid. When the slide block 18 slides toward the rotating rod 5, the insertion rod 181 will gradually approach the limiting hole on the rotating rod 5. When the insertion rod 181 is inserted into the limiting hole, the sliding of the slide block 18 is stopped, and the limiting of the rotating rod 5 can be completed.

[0034] In order to accommodate bottles of different heights, in some embodiments of this application, the fixing part includes a lifting plate and a support member 12. The lifting plate is fixedly connected to the top of the support member 12. The length of the support member 12 is adjustable. The lifting plate is provided with a linear drive device 8, a first clamping pouch 11 and a second clamping pouch 10.

[0035] By adjusting the length of the support member 12, it can accommodate bottles of different heights when testing torque. The support member 12 may include four telescopic rods, which are located at the four corners of the lifting plate.

[0036] In order to make the first clamping bladder 11 and the second clamping bladder 10 more stable in clamping the bottle body, in some embodiments of this application, the first clamping bladder 11 is connected to a first fixing plate, the second clamping bladder 10 is connected to a second fixing plate 9, the first fixing plate is connected to a linear drive device 8, the second fixing plate 9 is provided with an electromagnet 91, and the interior of the first clamping bladder 11 and the second clamping bladder 10 are both filled with magnetorheological fluid.

[0037] By filling the first clamping bladder 11 and the second clamping bladder 10 with magnetorheological fluid, when the two clamping bladders clamp the bottle body and approach each other, current can be passed to the electromagnet 91 to generate a magnetic field, which will cause the magnetorheological fluid in the first clamping bladder 11 and the second clamping bladder 10 to solidify rapidly, thereby improving the clamping stability of the bottle body.

[0038] Working principle: In use, slide the slide block 18 first, so that the slide block 18 slides towards the rotating rod 5, so that the insertion rod 181 on the slide block 18 is inserted into the limiting hole of the rotating rod 5 to limit the rotation of the rotating rod 5. Pull out the slide block 161 to release the engagement between the limiting block 162 and the two adjacent protrusions 62. Rotate the rotating shaft 3. The rotation of the rotating shaft 3 will cause the rotating body 6 to rotate. The fastener 61 of the rotating body 6 will gradually enter between the arc-shaped clamping plate 71 and the inner wall of the clamping member 7. As the fastener 61 enters, the cross-section of the fastener 61 will gradually increase. Then the fastener 61 will push the two arc-shaped clamping plates 71 to rotate around their own rotating shaft 3 and move closer to each other. The process of the two arc-shaped clamping plates 71 abutting against the bottle cap and then moving closer to each other will clamp the bottle cap. Once the bottle cap is clamped and fixed, the restriction of the insert rod 181 on the rotating rod 5 is released, and the limiting block 162 is engaged between two adjacent protrusions 62. Then, the rotating shaft 3 continues to rotate, causing the rotating body 6 to rotate. As the rotating body 6 continues to rotate, the clamping part and the rotating rod 5 will rotate, thereby causing the bottle cap to rotate relative to the bottle body.
