Description

Technical Field

[0001] This utility model relates to the technical field of torque measuring devices, and more specifically, to a bottle cap torque measuring device. Background Technology

[0002] A bottle cap torque tester is a device used to determine the torque value for locking and opening bottle caps on bottled, spouted, and tube packaged products. It is widely used to measure the torque value for locking and opening bottle caps on these products, and 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 the intermediate transportation of the product and its final consumption. It is the preferred product for bottle cap torque testing in the beverage, bottling, food, and pharmaceutical industries.

[0003] However, current bottle cap torque testing devices mainly use digital torque meters, which require manual twisting tests. Manual operation is subject to many influencing factors. To improve the accuracy and stability of the test through structural improvements, we propose a bottle cap torque measuring device to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a bottle cap torque measuring device, which improves the accuracy and stability of the testing process compared with manual operation of bottle caps.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A bottle cap torque measuring device includes a base, a clamp and a torque digital display mounted on the base, wherein the edge of the clamp is provided with a bracket whose bottom end is fixedly connected to the base.

[0009] A stepper motor is mounted on the top of the bracket. The power output end of the stepper motor is connected to a sleeve via a coupling. A telescopic rod is movably connected to the bottom end of the sleeve. A locking screw that tightly abuts against the telescopic rod is screwed onto the bottom side wall of the sleeve.

[0010] The bottom end of the telescopic rod is equipped with a connecting seat. The edge of the connecting seat is symmetrically provided with guide holes. The lower surface of the connecting seat is symmetrically fixedly connected with connecting ears at the edge between the guide holes. A double-ended screw is rotatably connected between the connecting ears. A movable seat is symmetrically screwed onto the double-ended screw. The upper surface of the movable seat is equipped with a guide post that slides and connects with the guide hole. The lower surface of the movable seat is provided with a threaded hole. A hexagonal bolt is screwed into the threaded hole. The outer side of the hexagonal bolt is covered with an anti-slip rubber sleeve.

[0011] Furthermore, the power output shaft of the stepper motor passes through the top of the bracket, and a bearing is installed at the part where the power output shaft of the stepper motor is combined with the bracket.

[0012] Furthermore, a rotating wheel is installed at one end of the double-ended screw, and the side wall of the rotating wheel is integrally formed with anti-slip protrusions.

[0013] Furthermore, the portion where the double-ended screw meets the connecting lug has a smooth surface, and a bearing is installed at the portion where the double-ended screw meets the connecting lug.

[0017] Furthermore, the outer wall of the anti-slip rubber sleeve is provided with anti-slip texture.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] (1) In this scheme, by driving the double-headed screw to rotate, the guide post slides through the guide hole on the connecting seat, so that the movable seats move towards each other until the anti-slip rubber sleeve is tightly attached to the outer wall of the bottle cap. By connecting the stepper motor to the external control device, the stepper motor's angular displacement is controlled by the control device to screw the bottle cap. The torque digital display will display the torque value in real time. Compared with manually screwing the bottle cap, this improves the accuracy and stability of the test process.

[0021] (2) This solution allows for adjustment of the position of the anti-slip rubber sleeve according to the height of the bottle body, and allows the hexagonal bolt to be screwed into the corresponding threaded hole according to the outer diameter of the bottle cap, thereby clamping the bottle cap and improving the applicability of the device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-6 A bottle cap torque measuring device includes a base 1, a clamp 2 and a torque digital display 3 mounted on the base 1, and a bracket 4 whose bottom end is fixedly connected to the base 1 at the edge of the clamp 2.

[0033] A stepper motor 5 is installed on the top of the bracket 4. The power output end of the stepper motor 5 is connected to a sleeve 6 through a coupling. A telescopic rod 7 is movably connected to the bottom end of the sleeve 6. A locking screw 8 that tightly abuts against the telescopic rod 7 is screwed onto the side wall of the bottom end of the sleeve 6.

[0034] A connecting seat 9 is installed at the bottom of the telescopic rod 7. Guide holes 10 are symmetrically opened on the edge of the connecting seat 9. Connecting ears 11 are symmetrically fixedly connected to the edge of the lower surface of the connecting seat 9 between the guide holes 10. Double-ended screws 12 are rotatably connected between the connecting ears 11. Movable seats 13 are symmetrically screwed onto the double-ended screws 12. Guide posts 17 that are slidably connected to the guide holes 10 are installed on the upper surface of the movable seats 13. Threaded holes 14 are opened on the lower surface of the movable seats 13. Hexagonal bolts 15 are screwed into the threaded holes 14. Anti-slip rubber sleeves 16 are covered on the outside of the hexagonal bolts 15.

[0035] It should be noted that when using this bottle cap torque measuring device, the bottom end of the bottle is first clamped by the clamp 2. Then, the height is adjusted by the telescopic rod 7 and the sleeve 6 so that the anti-slip rubber sleeve 16 at the hexagonal bolt 15 corresponds to the bottle cap. According to the outer diameter of the bottle cap, the hexagonal bolt 15 is screwed into the corresponding threaded hole 14. By driving the double-ended screw 12 to rotate, the guide post 17 slides through the guide hole 10 on the connecting seat 9, so that the movable seats 13 move towards each other until the anti-slip rubber sleeve 16 is tightly fitted to the outer wall of the bottle cap. The stepper motor 5 is connected to an external control device, which controls the angular displacement of the stepper motor 5 (the control device can control the forward and reverse rotation of the power output end of the stepper motor 5) to screw the bottle cap. The torque digital display 3 will display the torque value in real time. Compared with manual screwing of the bottle cap, the accuracy and stability of the testing process are improved.

[0036] like Figure 3 As shown, the power output shaft of the stepper motor 5 passes through the top of the bracket 4, and a bearing is installed at the part where the power output shaft of the stepper motor 5 is combined with the bracket 4.

[0037] It should be noted that the friction between the power output end of the stepper motor 5 and the bracket 4 was reduced, and the rotation accuracy of the power output end during operation was ensured.

[0038] like Figure 5 As shown, a rotating wheel is installed at one end of the double-ended screw 12, and the side wall of the rotating wheel is integrally formed with anti-slip protrusions;

[0039] It should be noted that the rotating wheel is designed to facilitate manual rotation of the double-headed screw 12.

[0040] like Figure 5 As shown, the part where the double-ended screw 12 and the connecting lug 11 are joined has a smooth surface structure, and a bearing is installed at the part where the double-ended screw 12 and the connecting lug 11 are joined.

[0041] It should be noted that the rotational accuracy of the double-ended screw 12 during rotation is guaranteed.

[0042] like Figure 5 , Figure 6As shown, one end of the hexagonal bolt 15 protrudes from the anti-slip rubber sleeve 16, and two hexagonal bolts 15 are symmetrically installed on each movable seat 13;

[0043] The hexagonal bolts 15 on the two movable seats 13 are symmetrically arranged in pairs, and the outer wall of the anti-slip rubber sleeve 16 is provided with anti-slip texture;

[0044] It should be noted that the hexagonal bolt 15 is screwed into the corresponding threaded hole 14 according to the outer diameter of the bottle cap, and the anti-slip texture provided on the outer wall of the anti-slip rubber sleeve 16 increases the friction between it and the bottle cap.

[0045] In use: First, use clamp 2 to hold the bottom of the bottle. Then, use telescopic rod 7 and sleeve 6 to adjust the height so that the anti-slip rubber sleeve 16 at the hexagonal bolt 15 corresponds to the bottle cap. According to the outer diameter of the bottle cap, screw the hexagonal bolt 15 into the corresponding threaded hole 14. Drive the double-ended screw 12 to rotate. Through the guide post 17 and the guide hole 10 on the connecting seat 9, slide the movable seats 13 towards each other until the anti-slip rubber sleeve 16 is tightly fitted to the outer wall of the bottle cap. Through the stepper motor 5 connected to the external control device, use the control device to control the angular displacement of the stepper motor 5 (the control device can control the forward and reverse rotation of the power output end of the stepper motor 5) to screw the bottle cap. The torque digital display 3 will display the torque value in real time.

[0046] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
