Description

Technical Field

[0001] The present application relates to the technical field of paint quality detection, and in particular to a device for detecting paint friction with a paper tape. Background Art

[0002] After the paint is produced, it is usually necessary to test the wear resistance of the paint. After the paint with good wear resistance is sprayed, it is not easy to form scratches on the paint surface. After the paint with poor wear resistance is sprayed on the surface of the car body, the paint layer is often damaged by slight scratches. Therefore, a device is needed to test the wear resistance of the produced paint.

[0003] In the existing device, a clamp is usually used to fix the sample coated with paint between two rollers with the same paper tape wound around them. The two rollers are used to reel in and unreel the paper tape respectively. The paper tape can pass over the paint surface and rub the paint to detect the wear resistance of the paint. However, the clamp is easy to be lost after the sample is removed after the test is completed. Utility Model Content

[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose a device for detecting paper tape friction paint.

[0005] The present application can be implemented through the following technical scheme: a device for detecting the friction of paper tape with paint, comprising a paper winding drum, a placing table and a pressing assembly. The two paper winding drums are provided with two paper winding drums, which are driven to rotate by a motor, and the two paper winding drums are wound with the same paper tape, and the two paper winding drums are used to roll up and unroll the paper tape respectively; the placing table is fixed between the two paper winding drums, and a clip is provided on the placing table, and the clip includes a fixing part and a clamping part, and the fixing part is installed on the placing table by screws, and the clamping part is used to clamp the sample coated with paint on the placing table; the pressing assembly can force the paper tape to contact the paint.

[0006] In the above technical solution, the paper winding drum is driven to rotate by a motor so that the two paper winding drums can unwind and rewind the paper tape respectively. The clamp is installed on the placement table by screws to prevent the clip from being lost. The clamp can clamp the sample on the placement table so that the position of the sample can be fixed relative to the two paper winding drums. The clamping assembly can force the paper tape to contact the paint on the sample so that the paper tape can rub against the paint when the paper winding drum is winding the paper tape, thereby detecting the wear resistance of the paint.

[0007] Furthermore, the pressing assembly includes a pressing member capable of contacting the paper tape and a driving assembly, wherein the driving assembly is used to drive the pressing member to move vertically so that the paper tape can contact the paint.

[0008] In the above technical solution, when the paper tape is used up, the driving assembly can drive the clamping member to move vertically away from the template so that a new paper tape can be placed under the clamping member, and then the driving assembly drives the clamping member to move linearly close to the template so that the paper tape contacts the template.

[0009] Furthermore, the driving assembly includes a mounting frame and a screw rod threadedly connected to the mounting frame, the screw rod is vertically arranged and rotatably connected to the clamping member, and scale lines are drawn on the vertical side wall of the mounting frame.

[0010] In the above technical solution, a screw is set and the pressing part can be moved vertically closer to or farther away from the sample by rotating the screw. During the rotation of the screw, the position of the pressing part relative to the scale line can be observed so that the pressure of the paper tape relative to the paint remains unchanged after the paper tape is replaced, thereby ensuring the accuracy of the test results.

[0011] Furthermore, it also includes a frame, on which a mounting block is rotatably connected, the mounting block and the paper winding drum are penetrated by a same bolt, and the bolt is threadedly connected to a nut.

[0012] In the above technical solution, the paper winding drum is connected to the mounting block by bolts and nuts, so that it is convenient for workers to replace the paper winding drum.

[0013] Furthermore, a torsion bar is provided at one end of the screw rod in the length direction away from the placement table.

[0014] In the above technical solution, the torsion rod makes it easy for workers to twist the screw rod, and the torsion rod can prevent the screw rod from being separated from the mounting frame.

[0015] Furthermore, the pressing member can fit with the vertical side wall of the mounting frame.

[0016] In the above technical solution, the pressing piece is in contact with the vertical side wall of the mounting frame, so that people can observe the position of the pressing piece relative to the scale line.

[0017] Furthermore, the two paper winding drums are each provided with two baffles capable of limiting the position of the paper tape.

[0018] In the above technical solution, the baffle can guide the moving path of the paper tape so that the paper tape can be accurately wound on the paper winding drum.

[0019] Furthermore, the pressing member includes a fixed block and a rotating roller rotatably mounted on the fixed block, the fixed block is rotatably connected to the screw rod, and the rotating roller can contact the paper tape.

[0020] In the above technical solution, by arranging a rotating roller to roll in contact with the paper tape, the paper tape can pass more smoothly between the pressing member and the template.

[0021] In summary, the present application has the following technical effects: the paper winding drum is driven to rotate by a motor so that the two paper winding drums can respectively unwind and reel in the paper tape; the clamp is installed on the placement table by screws to prevent the clip from being lost; the clamp can clamp the sample on the placement table so that the position of the sample can be fixed relative to the two paper winding drums; the clamping assembly can force the paper tape to contact the paint on the sample so that the paper tape can rub against the paint when the paper winding drum is winding the paper tape, thereby detecting the wear resistance of the paint.

The mounting block 10 at the rear end of the frame 9 is driven to rotate by the motor 2, so that the paper winding drum 1 at the rear end of the frame 9 can reel in the paper tape 3, and the paper winding drum 1 at the head end of the frame 9 can unwind the paper tape 3. The sample 7 coated with paint is fixed between the two paper winding drums 1, and the paper tape 3 is pressed against the paint surface by a pressing assembly 8, so that the paper tape 3 can rub the paint, thereby testing the wear resistance of the paint.

[0028] Please refer to the attached drawings in the instruction manual. Figure 3 A placing table 4 is installed on the frame 9, and the placing table 4 is located between the two paper winding drums 1. Two clamps 5 are installed on the placing table 4. The clamp 5 has a clamping portion 52 and a fixing portion 51. The fixing portion 51 of the clamp 5 is installed on the placing table 4 by screws 6. The clamping portion 52 can clamp the sample 7 so that the position of the sample 7 is fixed relative to the frame 9. The clamping assembly 8 includes a clamping member 81, and the clamping member 81 includes a fixing block 811. Four rotating rollers 812 are rotatably installed on the fixing block 811. The rotating rollers 812 are horizontally arranged and the axial outer wall can contact the paper tape 3. The fixing block 811 is driven by a driving assembly 82 to move vertically downward linearly so that the rotating rollers 812 can drive the paper tape 3 to contact the paint. The driving assembly 82 includes a mounting frame 821 mounted on the frame 9, the mounting frame 821 is threadedly connected with a screw rod 822, the screw rod 822 is placed vertically, the fixing block 811 is rotatably mounted on the bottom end of the screw rod 822, and a torsion bar 13 is mounted on the top end of the screw rod 822, the torsion bar 13 is horizontally arranged and always located above the mounting frame 821, and the torsion bar 13 can be held by hand to facilitate the screw rod 822.
