Description

Technical Field

[0001] The utility model relates to the technical field of tape testing equipment, in particular to a rolling testing machine. Background Art

[0002] Tapes are widely used in daily life and have a large usage volume. Therefore, when tapes are produced, a series of quality monitoring tests must be carried out on the tapes to ensure the production of high-quality tapes and improve the quality qualification rate of the tapes.

[0003] Regarding the testing of tapes, one of the tests is to test the adhesion of the tape. Before testing the adhesion of the tape, it is first necessary to attach the tape to the surface of a test plate for later adhesion testing. In order to evenly attach the tape to the test plate, an existing general electric rolling testing machine is used, and a roller is driven by an electric motor to roll the tape.

[0004] However, the test plate of the existing rolling testing machine is generally installed on the test bench of the rolling testing machine through four screws distributed at its four corners, which is rather troublesome when the test plate needs to be replaced. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is: to provide a rolling testing machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0006] The solution of the utility model to solve its technical problem is:

[0007] A rolling testing machine, comprising:

[0008] A test platform, the test platform is provided with an installation groove extending along the left and right, one end of the installation groove is set as an installation opening, and the installation opening is communicated with the side wall of the test platform;

[0009] A limiting block, the limiting block is arranged at the installation opening, the limiting block can slide relative to the test platform in the up and down direction, a reset elastic member is arranged between the limiting block and the test platform, and the reset elastic member makes the limiting block have a tendency to move upward relative to the test platform;

[0010] A test plate, the test plate is inserted and installed in the installation groove, a guiding component is arranged between the test plate and the installation groove, the guiding component includes a guiding groove and a guiding strip extending along the left and right, the guiding groove is slidably connected with the guiding strip, the guiding groove and the guiding strip are respectively arranged on the installation groove and the test plate, and one end of the test plate abuts against the limiting block;

[0011] A roller assembly, the roller assembly can move relative to the test platform in the left and right directions.

[0012] With the above technical solution, when installing the test board in this solution, first place the tape on the test board, and then insert and install the test board into the installation slot. The test board is restricted by the guiding component and the limiting block, which can prevent the test board from shifting during the test, thereby ensuring the test accuracy. Subsequently, control the roller assembly to roll over the tape to complete the rolling test. After the rolling test is completed, when disassembling, the staff presses the limiting block, and then the test board can be taken out. The installation and disassembly of the test board are simple and convenient.

[0013] As a further improvement of the above technical solution, one end of the limiting block away from the inner side of the installation slot is provided with a first chamfer, and the chamfer surface of the first chamfer is inclined upward.

[0014] With the above technical solution, during the process of inserting and installing the test board into the installation slot, the first chamfer will contact the test board, thereby guiding the limiting block, and the limiting block will move downward automatically, which can reduce the step of the staff pressing the limiting block first when inserting the test board, thus making the insertion of the test board more convenient.

[0015] As a further improvement of the above technical solution, the end of the test board is provided with a second chamfer, and the chamfer surface of the second chamfer is inclined downward.

[0016] With the above technical solution, during the process of inserting the test board into the installation slot, the second chamfer contacts the limiting block, causing the limiting block to move downward automatically, thereby preventing the limiting block from hindering the insertion of the test board. By setting it like this, the staff does not need to press the limiting block first and then install the test board, which can reduce the operation steps of the staff and is beneficial to improving the test efficiency.

[0017] As a further improvement of the above technical solution, the number of the second chamfers is two, and the two second chamfers are respectively arranged at both ends of the test board.

[0018] With the above technical solution, both ends of the test board can automatically press down the limiting block during the insertion process, reducing the trouble of distinguishing the two ends of the test board for insertion into the installation slot.

[0019] As a further improvement of the above technical solution, an elastic ejecting member is provided on the side wall of the installation slot away from the installation opening, and the elastic ejecting member makes the test board tend to move towards the installation opening.

[0020] Through the above technical solution, when the test board is completely inserted into the installation groove, the elastic ejection member is in a compressed state and stores elastic potential energy. When the limit block is pressed down, the test board is not restricted, and the elastic ejection member releases the elastic potential energy, causing the test board to move in the direction of the installation opening, so that the test board automatically pops out. After the test board automatically pops out, the upper end of the limit block abuts against the lower end of the test board, and the limit block cannot be reset. At this time, the staff can easily take out the test board. By setting like this, the steps for the staff to take out the test board can be reduced, which is beneficial to the rapid progress of the test work.

[0021] As a further improvement of the above technical solution, the cross-sectional shape of the guide strip is trapezoidal, and the guide groove matches the guide strip.

[0022] Through the above technical solution, the strength of the guide strip can be increased.

[0023] As a further improvement of the above technical solution, a plurality of height-adjustable foot cups are evenly arranged at the bottom of the test platform.

[0024] As a further improvement of the above technical solution, a pressing indication groove is provided at one end of the limit block away from the test board.

[0025] Through the above technical solution, the pressing indication groove is used to indicate the best pressing position for the staff, indicating that the staff's finger is placed at a place relatively far from the test board, so as to avoid the test board being automatically ejected by the elastic ejection member when pressing the limit block, resulting in a large impact between the test board and the staff's finger.

[0026] As a further improvement of the above technical solution, the pressing indication groove is in the shape of an ellipsoidal groove.

[0027] Through the above technical solution, it can better fit the staff's finger to improve comfort.

[0028] As a further improvement of the above technical solution, the guide groove is arranged on the side wall of the test board, and the guide strip is arranged on the side wall of the installation groove.

[0029] The beneficial effect of the present utility model is that the installation and disassembly of the test board are simple and convenient.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the present invention can be combined interactively without conflicting with each other.

[0038] Refer to Figures 1 to 4 , the rolling test machine includes: a test platform 100, a limiting block 200, a test plate 300 and a roller assembly 400.

[0039] An installation groove 110 for installing the test plate 300 is opened at the upper end of the test platform 100. The installation groove 110 is in a rectangular groove structure, and one end of the installation groove 110 is provided with an installation opening 111. The installation opening 111 is communicated with the side wall of the test platform 100, so that the test plate 300 can be inserted into the installation groove 110 from the installation opening 111.

[0040] Specifically, in this embodiment, four feet 120 are installed at the lower end of the test platform 100, and the four feet 120 are arranged in a rectangle. The height of the feet 120 is adjustable.

[0041] The limiting block 200 is a rectangular block structure. The limiting block 200 is installed on the test platform 100, and the limiting block 200 can be slidably connected to the test platform 100 in the up and down direction. The limiting block 200 is arranged at the installation opening 111, and the side walls at both ends of the limiting block 200 are in contact with the side walls of the installation groove 110. In other embodiments, the limiting block 200 can also be only arranged in the middle of the installation opening 111, and the side wall of the limiting block 200 is not in contact with the side wall of the installation groove 110. Those skilled in the art can select the installation position of the limiting block 200 and whether it is in contact with the side wall of the installation groove 110 according to actual needs.

[0042] Specifically, in this embodiment, a first chamfer 210 is arranged at one end of the limiting block 200 away from the installation groove 110, and the chamfer surface of the first chamfer 210 is inclined upward.

[0043] The test platform 100 is provided with a connection groove 130 for the limiting block 200 to enter. The limiting block 200 is slidably connected to the connection groove 130, and the limiting block 200 and the connection groove 130 slide in the up and down direction. When the limiting block 200 is pressed down until the upper end surface of the limiting block 200 is flush with or lower than the bottom of the installation groove 110, the test plate 300 can freely enter or exit the installation groove 110.

[0044] A reset elastic member 131 is arranged between the test platform 100 and the limiting block 200. The reset elastic member 131 is arranged in a stainless steel spiral spring structure. In other embodiments, the reset elastic member 131 can also be arranged as a spring piece or other structures. Those skilled in the art can select the reset elastic member 131 according to actual needs. When the limiting block 200 is pressed down, the reset elastic member 131 stores elastic potential energy. After the downward force on the limiting block 200 disappears, the reset elastic member 131 releases the elastic potential energy, and the reset elastic member 131 drives the limiting block 200 to move upward so that the limiting block 200 automatically resets. The reset of the limiting block 200 does not require additional operation by the staff, thereby avoiding the situation that the staff forgets to drive the limiting block 200 to reset and affecting the normal progress of the test.

[0045] The test plate 300 is inserted and installed in the installation groove 110. One end of the test plate 300 is in contact with the limiting block 200, and the limiting block 200 limits the test plate 300, thereby ensuring the smooth progress of the rolling test.

[0046] Specifically, in this embodiment, a second chamfer 310 is provided at the end of the test plate 300. The chamfer surface of the second chamfer 310 is inclined downward. During the process of inserting the test plate 300 into the installation groove 110, the first chamfer 210 and the second chamfer 310 cooperate to enable the limiting block 200 to move downward automatically, thereby preventing the limiting block 200 from hindering the insertion of the test plate 300. With this setting, the staff does not need to press down the limiting block 200 first and then install the test plate 300, which can reduce the operation steps of the staff and is beneficial to improving the test efficiency.

[0047] Specifically, in this embodiment, the number of the second chamfers 310 is set to two, and the two second chamfers 310 are respectively arranged at the left and right ends of the test plate 300. With this setting, both ends of the test plate 300 can automatically press down the limiting block 200 during the insertion process, reducing the trouble of distinguishing the insertion of the two ends of the test plate 300 into the installation groove 110.

[0048] A guiding component 500 is arranged between the installation groove 110 and the test plate 300.

[0049] Specifically, the guiding component 500 includes a guiding strip 510 and a guiding groove 520. Both the guiding strip 510 and the guiding groove 520 extend along the left-right direction. The guiding strip 510 and the guiding groove 520 are slidably connected along the left-right direction. The guiding strip 510 and the guiding groove 520 are respectively arranged on the test plate 300 and the installation groove 110. Specifically, in this embodiment, the guiding strip 510 is arranged on the side wall of the installation groove 110, and the guiding groove 520 is formed on the side wall of the test plate 300. In other embodiments, the guiding strip 510 can also be arranged on the side wall of the test plate 300, and the guiding groove 520 can be formed on the side wall of the installation groove 110. Those skilled in the art can select the installation positions of the guiding strip 510 and the guiding groove 520 according to actual needs.

[0050] Specifically, in this embodiment, the guiding strip 510 has a trapezoidal structure, and the wide side of the guiding strip 510 is arranged on the side away from the test plate 300 of the narrow side of the guiding strip 510. This setting can increase the strength of the guiding strip 510. The shape of the guiding groove 520 matches the shape of the guiding strip 510.

[0051] Specifically, in this embodiment, an elastic ejecting member 140 is provided on the side wall of the installation groove 110 away from the installation opening 111. The elastic ejecting member 140 is arranged as a stainless steel spiral spring structure. One end of the elastic ejecting member 140 is fixed to the test platform 100. When the test plate 300 is completely inserted into the installation groove 110, the elastic ejecting member 140 is in a compressed state and stores elastic potential energy. When the limiting block 200 is pressed down, the test plate 300 is not restricted. The elastic ejecting member 140 releases the elastic potential energy, causing the test plate 300 to move in the direction of the installation opening 111, so that the test plate 300 automatically pops out. After the test plate 300 automatically pops out, the upper end of the limiting block 200 abuts against the lower end of the test plate 300, and the limiting block 200 cannot be reset. At this time, the staff can easily take out the test plate 300. By setting it like this, the steps for the staff to take out the test plate 300 can be reduced, which is beneficial to the rapid progress of the test work.

[0052] Specifically, in this embodiment, a pressing indication groove 220 is formed at one end of the limiting block 200 away from the test plate 300. The pressing indication groove 220 is used to indicate the best pressing position for the staff, indicating that the staff's finger is placed at a place relatively far from the test plate 300, so as to avoid the test plate 300 being automatically ejected by the elastic ejecting member 140 when the limiting block 200 is pressed, resulting in a large impact between the test plate 300 and the staff's finger.

[0053] Specifically, in this embodiment, the pressing indication groove 220 is an ellipsoidal groove-like structure. Setting the pressing indication groove 220 as an ellipsoidal groove-like structure can better fit the staff's finger to improve comfort.

[0054] The roller assembly 400 includes a driving device 410, a moving frame 420, and a roller body 430.

[0055] The driving device 410 is fixedly installed on the test platform 100. Specifically, in this embodiment, the driving device 410 is arranged as a structure including a rotary motor, a synchronous pulley, and a synchronous belt. In other embodiments, the driving device 410 can also be arranged as a conventional linear driving device 410 or linear driving mechanism such as a linear motor or a linear cylinder. Those skilled in the art can select the specific structure of the driving device 410 according to actual needs.

[0056] The moving frame 420 is fixedly connected to the output end of the driving device 410. The driving device 410 drives the moving frame 420, so that the moving frame 420 moves relative to the test platform 100 in the left-right direction.

[0057] The roller body 430 moves in the left-right direction along with the moving frame 420. The roller body 430 is rotatably connected to the moving frame 420.

[0058] During the test, the staff first place the tape on the test plate 300, and then control the driving device 410 to drive the moving frame 420 and the roller body 430 to move in the left-right direction. When the roller body 430 moves in the left-right direction, due to the friction between the roller body 430 and the tape and the test plate 300, the roller body 430 rolls relative to the moving frame 420, thereby rolling the tape to complete the rolling test.

[0059] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
