Description

Technical Field

[0001] This utility model relates to the field of bottle cap friction testing technology, and in particular to a multi-angle friction test bench for bottle cap coating adhesion. Background Technology

[0002] The multi-angle friction test for bottle cap coating adhesion is a standardized test method specifically designed to simulate the various frictional contact angles that bottle caps may encounter during actual use, transportation, and storage, and to evaluate the ability of their surface coatings to resist wear and peeling.

[0003] During the friction test, the bottle cap is fixedly mounted on the movable clamp on the test bench. Then, the friction head is pressed down, and a weight is added to the friction head to simulate pressure. The clamp is then moved to drive the bottle cap back and forth across the friction head, thus achieving friction. After a specified number of reciprocations, the wear condition of the coating on the bottle cap surface is observed and weighed to complete the coating friction test.

[0004] Existing friction testing benches have fixed friction head direction and position during friction testing. This means that the friction head can only rub the top of the bottle cap. However, in actual use, the bottle cap is often most worn on the side. Testing the top alone will result in a large discrepancy between the actual results and the actual situation, making it inconvenient to use. Utility Model Content

[0018] This invention provides a multi-angle friction test bench for the adhesion of bottle cap coatings. It has the following beneficial effects:

[0019] 1. By pushing the plug-in block, the plug-in block engages with the slot inside the locking block, thereby causing the two locking blocks to open outward, thus unlocking the snap-fit ​​block.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a multi-angle friction test bench for the adhesion of bottle cap coating, including a cabinet 1. A fixed housing 4 is fixedly installed on the upper surface of the cabinet 1. A rotating shaft 5 is interspersed inside the fixed housing 4. A fixed plate 6 is fixedly installed on the top outer surface of the rotating shaft 5. A rotating box 8 is fixedly installed at the bottom end of the rotating shaft 5. A friction component 7 is provided inside the rotating box 8. An adjustment component 9 is provided inside the rotating box 8.

[0031] The friction assembly 7 includes a friction head 701 that is inserted inside the rotating box 8. The end of the friction head 701 away from the rotating shaft 5 is fixedly connected to a snap-fit ​​block 703 via a connecting block. A connecting plate 705 is provided inside the rotating box 8. Two locking blocks 704 are provided inside the connecting plate 705. A compression spring 706 is fixedly connected between the locking block 704 and the inner wall of the connecting plate 705. Two plug-in blocks 702 are provided on the outer surface of the friction head 701.

[0032] Specifically, a motor 10 is fixedly installed inside the fixed chassis 4. The output end of the motor 10 is connected to the outer surface of the rotating shaft 5 for transmission. A control chassis 3 is fixedly installed on the upper surface of the cabinet 1. A weighing platform 2 is set on the upper surface of the cabinet 1. A clamping component 11 is set on the upper surface of the cabinet 1. The weighing platform 2 facilitates weighing and testing after the test is completed.

[0033] Specifically, both the outer surfaces of the latching block 703 and the locking block 704 are provided with mutually cooperating inclined surfaces. The locking block 704 has a slot inside that cooperates with the insertion block 702. The outer surface of the insertion block 702 near the locking block 704 and the inner wall of the slot are provided with mutually cooperating inclined surfaces. Through the mutual cooperation of the inclined surfaces on the outer surfaces of the latching block 703 and the locking block 704, the insertion of the latching block 703 can drive the locking block 704 to open outward. Through the mutually cooperating inclined surfaces on the outer surface of the insertion block 702 near the locking block 704 and the inner wall of the slot, the insertion of the insertion block 702 can drive the locking block 704 to open outward, thereby unlocking the insertion block 702.

[0034] Specifically, the outer surface of the friction head 701 is provided with a limiting groove that cooperates with the insertion block 702. Both sides of the friction head 701 are provided with limiting protrusions. The inner wall of the limiting groove is provided with a groove that cooperates with the limiting protrusions. Through the cooperation of the limiting groove, the limiting protrusions and the groove, the limiting insertion block 702 can move laterally, so that the insertion block 702 can be accurately inserted into the slot inside the locking block 704, and the insertion block 702 will not separate from the friction head 701. Furthermore, the end of the insertion block 702 away from the connecting plate 705 will not protrude beyond the friction head 701, thus not affecting the friction test.

[0035] Specifically, the outer surface of the friction head 701 is provided with a keyway, and the outer surface of the rotating box 8 is provided with a socket that mates with the friction head 701. The inner wall of the socket is provided with a flat key that mates with the keyway. By setting the keyway and the flat key, the friction head 701 is prevented from rotating, and the friction head 701 is ensured to accurately drive the plug block 702 to engage with the locking block 704.

[0036] Furthermore, by pushing the insertion block 702 on the outer surface of the friction head 701, the insertion block 702 is inserted into the connecting plate 705, thereby engaging the insertion block 702 with the slot inside the locking block 704. This causes the two locking blocks 704 to open outward, thus unlocking the locking block 703 and unlocking the friction head 701. Then, a new friction head 701 is inserted into the rotating box 8. The inserted locking block 703 engages with the inclined surface of the outer surface of the locking block 704, thereby causing the locking block 704 to open outward, which in turn causes the locking block 703 to insert, locking... After the connecting block 703 is inserted, the locking block 704 is reset under the action of the compression spring 706, thereby locking the connecting block 703 and finally completing the replacement of the friction head 701. The replacement is convenient and quick. When clamping and fixing the bottle cap, it needs to be fixed with the existing contouring seat. The bottle cap is inserted into the contouring seat, and then the contouring seat is clamped by the clamping component 11. The connection relationship, working principle and operation sequence between the clamping component 11, the control box 3 and the weighing platform 2 and other components are existing technologies and are common knowledge known to those skilled in the art.

[0037] Example 2

[0038] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The adjusting component 9 includes a pressure spring 906 fixedly connected to the side of the connecting plate 705 away from the friction head 701. The end of the pressure spring 906 away from the friction head 701 is fixedly connected to a movable plate 902. A threaded sleeve 905 is fixedly connected inside the movable plate 902. A bolt 904 is engaged inside the threaded sleeve 905. The end of the bolt 904 away from the friction head 701 is movably connected to the outer surface of the rotating box 8.

[0039] Specifically, a limiting rod 901 is fixedly connected to one end of the connecting plate 705 near the movable plate 902. A stop block is fixedly connected to the other end of the limiting rod 901 away from the connecting plate 705 through the interior of the movable plate 902. A fixing ring is provided on the outer surface of the connecting plate 705. A circular groove that mates with the fixing ring is provided inside the rotating box 8. The limiting rod 901 prevents the movable plate 902 from rotating. The stop block prevents the limiting rod 901 from disengaging from the movable plate 902. The fixing ring and the circular groove keep the connecting plate 705 within the circular groove inside the rotating box 8.

[0040] Specifically, two scale plates 903 are fixedly connected to the side of the movable plate 902 away from the connecting plate 705. The end of the scale plate 903 away from the movable plate 902 passes through the outer surface of the rotating box 8. The part of the scale plate 903 protruding from the rotating box 8 assists the operator in controlling the preload of the pressure spring 906.

[0041] Furthermore, by using a tool to rotate the bolt 904, the rotation of the bolt 904 causes the threaded sleeve 905 to move the movable disc 902 on the surface of the bolt 904, thereby adjusting the preload of the pressure spring 906. This adjusts the lateral compressive force generated when the friction head 701 compresses the pressure spring 906, and further adjusts the lateral compressive force experienced when the bottle cap is inserted into the rotating box 8. The adjustment component 9 is only set between the two lateral friction components 7 and the inner wall of the rotating box 8. The adjustment component 9 is not set above the top friction component 7. Vertical pressure adjustment is mainly achieved by the counterweight inserted into the fixed disc 6.

[0042] Working principle: During the friction test of the coating adhesion of the bottle cap, the bottle cap is inserted into the contour base, and then the bottle cap and the contour base are installed on the clamping component 11 for fixed installation. Then, the friction component 7 is replaced according to the type of bottle cap. By pushing the insertion block 702 on the outer surface of the friction head 701, the insertion block 702 is inserted into the connecting plate 705, so that the insertion block 702 engages with the slot inside the locking block 704, thereby causing the two locking blocks 704 to open outward, thus unlocking the locking block 703 and unlocking the friction head 701. Then, the new friction head 701 is inserted into the rotating box 8. The inserted locking block 703 engages with the inclined surface of the outer surface of the locking block 704, thereby causing the locking block 704 to open outward, thus causing the locking block 703 to be inserted. After the locking block 703 is inserted, the locking block 704 is reset under the action of the compression spring 706, thereby locking the locking block. 703. Finally, the friction head 701 is replaced. The replacement is quick and easy. After the friction head 701 is replaced, the adjustment component 9 is adjusted. The bolt 904 is turned with a tool. The rotation of the bolt 904 causes the threaded sleeve 905 to move the movable plate 902 on the surface of the bolt 904, thereby adjusting the preload of the pressure spring 906. This adjusts the lateral compressive force generated when the friction head 701 compresses the pressure spring 906, and thus adjusts the lateral compressive force when the bottle cap is inserted into the rotating box 8, ensuring the accuracy of the friction test results. The vertical pressure is achieved by the counterweight block inserted into the fixed plate 6. Then, the motor 10 drives the rotating shaft 5 to rotate, thereby driving the friction head 701 to rub the top and sides of the bottle cap, achieving multi-angle friction and avoiding friction from only the top, thus improving the test accuracy. Finally, the friction test of the coating adhesion of the bottle cap is completed.
