Description

Technical Field

[0001] This utility model relates to the technical field of tape viscosity testing equipment, and in particular to a tape viscosity testing device for tape production. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding. The adhesive can stick things together because its molecules form bonds with the molecules of the objects to be connected. These bonds can firmly bind the molecules together.

[0003] Utility model CN215574564U discloses a tape viscosity testing device for tape production, including a base and a mounting base. The mounting base has a motor slot and two fixing slots. A first connecting block is provided on the lower side wall of the mounting base. The motor slot and the two fixing slots are fixedly connected. A dual-axis motor is fixedly connected to the inner wall of the motor slot. Rotating rods are fixedly connected to the two output shafts of the dual-axis motor. Both rotating rods penetrate the side walls of the motor slot and the fixing slots. The connection between the two rotating rods and the side walls of the motor slot and the fixing slots is sealed and rotatably connected. A first helical gear is fixedly connected to the end of each rotating rod away from the dual-axis motor. This utility model can perform more accurate viscosity testing of tapes. The viscosity testing structure can be directly displayed digitally via a pointer, reducing the workload of operators, improving testing efficiency, and ensuring the accuracy of the testing structure.

[0004] The device disclosed in the above utility model drives the connecting rope to rotate the second rotating rod by moving the second connecting block, thereby achieving the purpose of detecting the viscosity of the tape. However, after the first round of detection, the connecting rope is in an unfolded state and cannot automatically wrap around the second rotating rod, making it difficult to return to the initial state. This makes it inconvenient to perform multiple tests on the tape and has low practicality. Utility Model Content

[0005] The purpose of this invention is to provide a tape viscosity testing device for tape production, so as to solve the problems mentioned in the background art, such as the inconvenience of multiple tape tests and low practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tape viscosity testing device for tape production, comprising a base, a U-shaped support frame mounted on the base, a servo motor mounted on one side of the U-shaped support frame, a bidirectional lead screw connected to the output shaft of the servo motor, the bidirectional lead screw being rotatably connected to the U-shaped support frame, and two moving blocks threadedly connected to the bidirectional lead screw respectively, each of the two moving blocks being rotatably connected to a connecting rod, the ends of the two connecting rods away from the moving blocks being rotatably connected to the same first detection block, a second detection block being disposed below the first detection block, and an S-shaped force sensor being disposed on the same side of the first and second detection blocks.

[0007] Preferably, the upper part of the U-shaped support frame has a limiting groove, and the tops of the two moving blocks are slidably fitted into the limiting groove.

[0008] Preferably, the base is provided with a support platform, and the second detection block is located on the support platform.

[0009] Preferably, the bottom of the second detection block is provided with an L-shaped hook, and the base is provided with a plug rod. The height of the plug rod after it is connected to the L-shaped hook is the same as the height of the support platform.

[0010] Preferably, the base is provided with a connector, and the plug rod is rotatably connected to the base in the horizontal direction through the connector.

[0011] Preferably, the support platform is provided with a connecting groove, which is adapted to the L-shaped hook.

[0012] Preferably, a photoelectric sensor is provided on the U-shaped support frame, and the height of the photoelectric sensor is the same as the height of the top of the second detection block.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the mechanical bonding of the first and second detection blocks can be achieved by controlling the movement of the first detection block, ensuring that the first and second detection blocks are always under the same conditions during each test, thus avoiding errors caused by manual operation. The device uses an S-shaped sensor on the same side of the first and second detection blocks, with both ends of the S-shaped sensor connected to the first and second detection blocks respectively. When the first detection block detaches from the second detection block, the S-shaped force sensor can directly detect the viscosity of the tape. The entire detection process is simple and fast, and it can achieve multiple cyclic tests on the tape, making it highly practical. Attached Figure Description

[0020] 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.

[0021] Reference Figure 1-4 A tape viscosity testing device for tape production includes a base 1, a U-shaped support frame 2 mounted on the base 1, a servo motor 3 mounted on one side of the U-shaped support frame 2, a bidirectional lead screw 4 connected to the output shaft of the servo motor 3, the bidirectional lead screw 4 being rotatably connected to the U-shaped support frame 2, and two moving blocks 5 threadedly connected to the bidirectional lead screw 4 respectively, each of the two moving blocks 5 being rotatably connected to a connecting rod 6, the ends of the two connecting rods 6 away from the moving blocks 5 being rotatably connected to the same first detection block 7, a second detection block 8 being provided below the first detection block 7, and an S-shaped force sensor 9 being provided on the same side of the first detection block 7 and the second detection block 8.

[0022] In use, the device involves applying adhesive to the second detection block 8, then controlling the servo motor 3 to rotate. The servo motor 3 drives the bidirectional lead screw 4 to rotate synchronously, causing the two moving blocks 5 to approach each other. This moves the first detection block 7 downwards until it fully contacts the second detection block 8, thus achieving complete adhesion between them. This method ensures consistent adhesion strength between the first and second detection blocks 7 and 8 during each test, avoiding inconsistencies and errors associated with manual adhesion. Next, an S-shaped force sensor 9 is connected to the same side of the first and second detection blocks 7 and 8. After placing the S-shaped force sensor 9 between the two blocks, the servo motor 3 is controlled to rotate in the opposite direction, driving the bidirectional lead screw 4 to rotate in the opposite direction. This moves the two moving blocks 5 away from each other, causing the first detection block 7 to move upwards and peel off from the second detection block 8. Simultaneously, the S-shaped force sensor 9 detects the peeling force of the first detection block 7 from the second detection block 8, thus achieving the purpose of detecting the tape viscosity.

[0023] Specifically, in this embodiment, a limiting groove 10 is provided on the upper part of the U-shaped support frame 2, and the tops of the two moving blocks 5 are slidably adapted in the limiting groove 10, so that the two moving blocks 5 can be slidably connected to the U-shaped support frame 2 through the limiting groove 10, thereby restricting the moving direction of the moving blocks 5, so that the two moving blocks 5 can only move in the horizontal direction, thereby achieving the purpose of adjusting the height of the first detection block 7.

[0024] Specifically, in this embodiment, a support platform 11 is provided on the base 1, and the second detection block 8 is located on the support platform 11, so that when the first detection block 7 moves downward to contact the second detection block 8, the support platform 11 can provide support for the second detection block 8, thereby assisting the first detection block 7 and the second detection block 8 to stick together.

[0025] Specifically, in this embodiment, the bottom of the second detection block 8 is provided with an L-shaped hook 12, and the base 1 is provided with a connecting rod 13. The height of the connecting rod 13 after it is connected to the L-shaped hook 12 is the same as the height of the support platform 11, so that when the connecting rod 13 is connected to the L-shaped hook 12, the bottom of the second detection block 8 can be kept in contact with the support platform 11, thereby facilitating the control of the first detection block 7 to apply pressure to the second detection block 8. At the same time, the connection state of the connecting rod 13 and the L-shaped hook 12 can restrict the second detection block 8, preventing the first detection block 7 from driving the second detection block 8 to move upward, so as to facilitate the peeling of the first detection block 7 from the second detection block 8.

[0026] Specifically, in this embodiment, a connector 14 is provided on the base 1, and the plug rod 13 is rotatably connected to the base 1 in the horizontal direction through the connector 14, so as to facilitate the control of the distance between the plug rod 13 and the L-shaped hook 12 by rotating the plug rod 13, thereby facilitating the connection between the plug rod 13 and the L-shaped hook 12.

[0027] Specifically, in this embodiment, a connecting groove 15 is provided on the support platform 11. The connecting groove 15 is adapted to the L-shaped hook 12, so that the L-shaped hook 12 connected to the bottom of the second detection block 8 can pass through the connecting groove 15 through the support platform 11 and connect to the plug rod 13, thereby ensuring the normal connection between the plug rod 13 and the L-shaped hook 12.

[0028] Specifically, in this embodiment, a photoelectric sensor 16 is provided on the U-shaped support frame 2. The height of the photoelectric sensor 16 is the same as the height of the top of the second detection block 8, so that during the detection process, the photoelectric sensor 16 can determine the moment of separation between the first detection block 7 and the second detection block 8, thereby improving the automation and accuracy of the measurement.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
