Description

Technical Field

[0001] The utility model relates to a pressing roller device, in particular to a pressing roller device for testing the peeling strength of an adhesive tape, and belongs to the technical field of adhesive tape testing. Background Art

[0002] Adhesive tape is composed of two parts: a base material and an adhesive. It connects two or more unconnected objects together by bonding, and a layer of adhesive is coated on its surface.

[0003] During the production process of tape, the peel strength of the tape needs to be tested. The peel strength testing method in the existing technology usually requires the staff to stick the test tape sample on different boards, and then use the staff to press the tape stuck on the board with a handheld pressure roller. Finally, the pressed sample is installed on the peel strength tester for testing.

[0004] During the sample lamination process, various test standards (such as DIN1939-1996 and GB2792-2014) must be referenced, requiring one or more reciprocating press cycles at a fixed pressure and speed. Currently, the lamination process involves a handheld roller, assisted by a timer. However, the speed and pressure generated by manual operation of the roller cannot be guaranteed to be consistent, leading to significant operational errors in the measurement results and hindering accurate assessment of the tape's peel strength.

[0005] Therefore, it is necessary to provide a pressure roller device for testing the peeling strength of an adhesive tape. Summary of the Invention

DETAILED DESCRIPTION

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] A pressure roller 2 device for testing the peeling strength of an adhesive tape consists of a placement platform 1, a driving component, a rolling component and a pressing component.

[0037] The sample groove is located on the top surface of the placement table 1 and extends along the length of the placement table 1. The sample groove is used to place the sample plate with the tape applied to it to be rolled. Preferably, the sample groove can be configured in a T-shape, with a T-shaped slot die 11 embedded therein. The roller groove is located on the top surface of the slot die 11 and extends along the length of the placement table 1. That is, the sample plate is placed in the roller groove. By replacing different slot dies 11, the roller groove of different depths and widths can be achieved, thereby accommodating tape-applied samples of different thicknesses and widths, or samples with tape applied to them of different thicknesses and widths.

[0038] The driving assembly consists of a pair of brackets 8, a crossbeam 9, a first screw rod 6 and a slider 5.

[0039] A pair of brackets 8 are vertically mounted at either end of the top surface of the platform 1 and are parallel to each other. A crossbeam 9 is positioned between the brackets 8, with both ends fixedly connected to the brackets 8. A first screw rod 6 is positioned parallel to the bottom of the crossbeam 9, with one end axially connected to the bracket 8 and the other end rotated by the motor 7 through the bracket 8. A slider 5 is threaded onto the first screw rod 6, and a slide rail 10 is provided on the top surface of the slider 5. The bottom surface of the crossbeam 9 is provided with a slide groove that matches the slide rail 10. In other words, the motor 7 shaft rotates the first screw rod 6, causing the slider 5 to slide along the length of the platform 1 within the slide groove via the slide rail 10.

[0040] The rolling assembly consists of a pressure roller 2, a roller seat 3 and a cylinder 4.

[0041] Preferably, the cylinder 4 is a pair, fixed on both sides of the slider 5 and arranged longitudinally. The driving end of the cylinder 4 is fixed to the ear blocks 12 on both sides of the roller seat 3. The roller seat 3 is an inverted U-shape, and the pressure roller 2 is arranged in the roller seat 3 through the roller shaft.

[0042] That is, the cylinder 4 pushes the roller seat 3 up and down, so that the pressure roller 2 rolls the tape on the sample. Then, the slider 5 moves horizontally, and the pressure roller 2 rolls along the length direction on the sample to achieve the purpose of rolling the tape.

[0043] The pressing assembly is used to fix the sample that has been rolled over the tape. The pressing assembly consists of several pairs of pressure strips 17, a crossbar 14 with pressure blocks 15 at both ends, and a second screw rod 13.

[0044] Several pairs of pressure strips 17 are symmetrically positioned along the length of the sample slot. These strips 17 are L-shaped and comprise a transverse rod and a longitudinal rod. The bottom end of the longitudinal rod is secured to the platform 1 via a rotating shaft secured with a compression spring. When the compression spring releases its elastic force, the transverse rod rotates away from the sample slot along the rotating shaft. The inner side of the longitudinal rod is provided with a first pressure surface inclined at 45°. On either side of the first pressure surface are chamfered surfaces that meet the end face of the pressure strip 17. These chamfered surfaces serve as first guide surfaces 18.

[0045] The outer side of the pressure block 15 is provided with a second pressure surface inclined at 45 degrees, which matches the first pressure surface; that is, when the second pressure surface is in contact with the first pressure surface, the transverse rod of the pressure strip 17 is horizontal and presses the sample placed in the sample groove and rolled over by the tape. Beveled surfaces are provided on both sides of the second pressure surface, which are beveled to the end surface of the pressure block 15. These beveled surfaces serve as second guide surfaces 16. The second guide surfaces 16 are used to contact and press the first guide surface 18. As the pressure block 15 moves, the second guide surfaces 16 gradually contact and press the first guide surface 18, causing the pressure block 15 to rotate about the rotating shaft, the compression spring is in a compressed state, and the transverse rod rotates toward the sample groove.

[0046] A crossbar 14 is positioned horizontally within a transverse groove at the bottom of the platform 1 and is threaded onto the second screw 13. The second screw 13 is parallel to the first screw 6, and the ends of the second screw 13 and the first screw 6 are linked via a linkage with helical gears at both ends. The rotation of the first screw 6, through the linkage, drives the second screw 13, causing the crossbar 14 to translate within the transverse groove along the length of the platform 1. This in turn drives the pressure blocks 15 at its ends to sequentially press each pair of pressure strips 17 together.

[0047] Preferably, the cross bar 14 is placed at the rear end of the pressure roller 2, that is, as the pressure roller 2 rolls forward, the cross bar 14 moves forward synchronously, and in the process of moving forward, each pair of pressure strips 17 is pressed in turn, so that the pressure strips 17 press the sample that is rolled by the pressure roller 2 over the tape in turn, thereby fixing the tape and the sample while preventing the tape and the sample from being driven forward by the pressure roller 2.

[0048] When using,

[0049] Place the sample with tape on it in the sample slot.

[0050] Start the motor 7 to make the pressing roller 2 repeatedly roll on the surface of the sample, so that the tape is evenly attached to the surface of the sample, thereby completing the pressing process of the sample and the tape, so as to facilitate the subsequent glass strength test.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the scope of protection of the present invention.
