Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of testing devices, and more specifically to a device for testing the composite fastness of transfer paper. Background Art
[0002] The existing test scheme for the composite fastness of transfer paper is to manually operate with the tape pulling and peeling method, that is, to stick 3M tape with a width of 20mm for 1 minute, quickly pull and peel, and observe through light to see if there are small translucent spots on the transfer paper. However, since it is manually pasted, the width of the tape cannot be too large. This method can only randomly check the composite fastness of local areas, that is, the fastness of the tape coverage range. However, the gluing of transfer paper changes with the rubber roller as a cycle (600-700mm plate cycle). Obviously, this sampling method has defects. It cannot detect defects such as uneven gluing outside the tape coverage area, and the periodic peeling caused by dirty spots on the screen roller is also unlikely to be detected. In addition, the pulling and peeling speed and pressure cannot be standardized for manual operation, so it is urgently needed to improve this. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figures 1 to 5As shown, a device for testing the composite fastness of transfer paper includes a workbench 1, a driving roller 2, a pressure roller 3 and a tape roller 4, a conveying plate 11 is fixed above the workbench 1, the driving roller 2 is located at the lower part of the conveying plate 11 and the pressure roller 3 is located at the upper part of the conveying plate 11, the pressure roller 3 can abut the driving roller 2, the tape roller 4 is located above the pressure roller 3, the pressure roller 3 and the tape roller 4 are connected by a belt 6, a first transmission wheel 31 is fixed at one end of the pressure roller 3, a second transmission wheel 41 is fixed at one end of the tape roller 4, the first transmission wheel 31 and the second transmission wheel 41 are connected by the belt 6, and the pressure roller 3 can be rotated to The adhesive tape roller 4 can be driven to rotate, and the adhesive tape unwound by the adhesive tape roller 4 can be transmitted between the pressure roller 3 and the driving roller 2. A first support frame 12 is fixed on the upper part of the workbench 1, and the first support frame 12 is located on both sides of the transmission plate 11. The two ends of the driving roller 2 and the pressure roller 3 are respectively connected to the two first support frames 12, and a second support frame 13 is installed on the side of the first support frame 12. The two ends of the adhesive tape roller 4 are respectively connected to the second support frame 13. A motor 5 is installed on the upper part of the workbench 1, and the motor 5 is connected to the driving roller 2. The motor 5 can drive the driving roller 2 to rotate, and the driving roller 2 can drive the pressure roller 3 to rotate.
[0026] like Figure 1 As shown, the tape roller 4 is provided with a tape roll, and by rotating the tape roller 4, the tape roll can be driven to be wound or unwound. When a test is required, the tape roll needs to be unwound first, so that the tape on the tape roll passes from right to left between the pressure roller 3 and the driving roller 2, and then the transfer paper 9 is placed flat on the upper part of the conveying plate 11 on the right side of the pressure roller 3, and the end of the transfer paper 9 is embedded between the pressure roller 3 and the driving roller 2, so that the end of the transfer paper 9 contacts the lower surface of the tape. At this time, the driving roller 2 is driven counterclockwise by the motor 5, and the driving roller 2 can drive the pressing roller 3 and the tape roller 4 to rotate, so that the tape and the transfer paper 9 are transmitted from right to left, and the tape and the surface of the transfer paper 9 are bonded by the pressing roller 3; when most of the transfer paper 9 is located on the left side of the pressing roller 3, the motor 5 drives the driving roller 2 to rotate clockwise, and the transfer paper 9 can be transmitted from left to right. In the transmission process, the operator presses the transfer paper 9 to prevent the transfer paper 9 from warping, and the tape roller 4 rewinds the tape roll, so that the tape can be torn off the surface of the transfer paper 9, so as to realize the test of the composite fastness of the transfer paper 9.
[0027] In the utility model, through the coordinated transmission of the driving roller 2, the pressure roller 3 and the tape roller 4, the compounding, conveying and peeling of the transfer paper 9 and the tape can be realized, so that the composite fastness test of the transfer paper 9 can be realized. Through the drive of the motor 5, the consistency of the peeling speed can be effectively guaranteed. By setting the pressure roller 3 and the tape roller 4, the adhesion of a large width tape to the surface of the transfer paper 9 can be realized, which greatly improves the accuracy and consistency of the test results.
[0028] The two ends of the pressure roller 3 are connected to the limiting blocks 32, and the pressure roller 3 and the limiting blocks 32 are rotatably connected through bearings. The limiting blocks 32 are located in the first support frame 12, and a limiting slide groove 14 is provided inside the first support frame 12. The two ends of the limiting blocks 32 are inserted into the limiting slide groove 14. The limiting blocks 32 can move along the limiting slide groove 14 so that the pressure roller 3 can move up and down. By setting the pressure roller 3 that can move up and down, it is convenient to pass the tape between the pressure roller 3 and the driving roller 2 before testing, which can effectively ensure that the pressure roller 3 can abut the surface of the driving roller 2, meet the test of transfer papers 9 with different thicknesses, effectively ensure the standardization of the test pressure, and improve the accuracy of the test.
[0029] The outer side of the second support frame 13 is connected to the tensioning wheel 8, and the first transmission wheel 31, the second transmission wheel 41 and the tensioning wheel 8 are connected through the belt 6. Specifically, a guide sleeve 16 is provided on the outer side of the second support frame 13, and an adjusting block 81 is installed in the guide sleeve 16. The adjusting block 81 can move along the guide sleeve 16, and the adjusting block 81 is connected to the tensioning wheel 8. A convex plate 17 is provided on the side of the guide sleeve 16 away from the tensioning wheel 8, and a first handle bolt 18 is threadedly connected to the convex plate 17. The first handle bolt 18 passes through the convex plate 17 and the protruding end abuts against the side of the adjusting block 81. Since the pressure roller 3 can move up and down, it is necessary to adjust the tension of the belt 6 through the tensioning wheel 8. When the first handle bolt 18 is turned and the adjusting block 81 is pushed to move, the tension of the belt 6 can be increased.
[0030] Through the cooperation between the adjusting block 81 and the guide sleeve 16, the movement of the tensioning wheel 8 can be guided and limited. By setting the first handle bolt 18, not only the tensioning force of the belt 6 can be adjusted, but also the adjusting block 81 can be limited to prevent the adjusting block 81 from moving back during the test, thereby improving the reliability of the structure.
[0031] like Figure 3As shown, the pressure roller 3 can adjust the pressure on the driving roller 2 through the adjusting mechanism 7. The driving roller 2 is a rubber roller. A support block 15 is fixed to the upper part of the first support frame 12. The adjusting mechanism 7 includes a slider 71, a second handle bolt 72 and a spring 73. The slider 71 is located in the first support frame 12 and the two ends of the slider 71 are inserted into the limiting slide groove 14 for limiting. The second handle bolt 72 passes through the support block 15 and is connected to the support block 15 by a thread. The end of the second handle bolt 72 that passes through the lower part of the support block 15 abuts against the upper part of the slider 71. The lower end of the spring 73 abuts against the upper part of the limiting block 32 and the upper end abuts against the lower part of the slider 71. When it is necessary to increase the pressure of the pressure roller 3, the slider 71 is pushed down by twisting the second handle bolt 72, and the spring 73 is compressed. At this time, the pressure of the pressure roller 3 can be increased. By setting the adjusting mechanism 7, the pressure of the pressure roller 3 can be adjusted, so that the composite fastness of the transfer paper 9 can be tested under different pressures.
[0032] A first limiting sleeve 33 is provided on the upper portion of the limiting block 32, and a second limiting sleeve 74 is provided on the lower portion of the sliding block 71. Both ends of the spring 73 are respectively inserted into the first limiting sleeve 33 and the second limiting sleeve 74. By providing the first limiting sleeve 33 and the second limiting sleeve 74, the spring 73 can be installed and limited, thereby improving the reliability of the structure.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
