Description

Technical Field

[0001] The invention relates to the technical field of initial adhesion testing, and more particularly to a device for testing the initial adhesion of a plaster or a patch. Background Art

[0002] The initial adhesion test device is a professional equipment specially used to evaluate the initial adhesion of materials such as tapes and adhesives. It is mainly suitable for the initial adhesion test of products such as pressure-sensitive tapes, medical patches, self-adhesive labels, and protective films.

[0003] The initial adhesion test device usually adopts the inclined ball rolling method, which tests the initial adhesion of the sample by the adhesion of the adhesive tape to the steel ball when the steel ball and the sticky surface of the sample are in short contact with a small pressure. During the test, the steel ball is rolled over the sticky surface of the adhesive tape placed flat on the inclined plate, and the initial adhesion is evaluated based on the maximum steel ball size that can be adhered to the sticky surface of the specified length.

[0004] When using the existing initial adhesion test device, the test sample (ointment, patch) is generally first adhered to the test bench with double-sided tape, and then steel balls of different sizes are released manually. The initial adhesion test result can be obtained based on the largest steel ball that the test sample (ointment, patch) can adhere to. However, after the test is completed, the double-sided tape remaining on the test bench needs to be cleaned with a tool, which is not only cumbersome to operate, but may also cause damage to the table during the cleaning process. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a device for testing the initial adhesion of plasters and patches, which can fix the test sample (ointment, patch) without tape, is easy to disassemble without damaging the table surface, and automatically controls the ball release speed to avoid affecting the initial kinetic energy of the steel ball and the initial adhesion result error.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A device for testing the initial adhesion of plasters and patches, comprising a base, an inclined plate rotatably mounted on the base, a steel ball release mechanism mounted on the inclined plate, an adjustment component and a fixing fixture, wherein the fixing fixture comprises two sets of symmetrically arranged sliding guide rails, each set of the sliding guide rails having two sets of limit sliders slidably mounted thereon, each set of the limit sliders having a set of clamping members mounted thereon, each set of the clamping members comprising a limit sleeve, a lifting rod arranged inside the limit sleeve and a lifting block arranged on the top of the limit sleeve.

[0008] The present invention is further configured as follows: each group of the sliding guide rails includes two groups of mounting members arranged along the length direction of the inclined plate, a sliding rod and a pulley are arranged between the two groups of the mounting members, and one end of the pulley is connected to a motor.

[0009] The present invention is further configured as follows: each group of the limit sliding blocks is sleeved on the slide rod, each group of the limit sliding blocks is provided with a slide groove adapted to the shape of the slide rod, and each group of the limit sliding blocks is provided with a mounting through hole on one side close to the center of the inclined plate.

[0010] By adopting the above technical solution, the four groups of limiting sliders move along the sliding guide rails, synchronously driving the four groups of clamping members to adjust their positions, so that the four groups of clamping members can limit the test samples (ointments, patches) at the four corners.

[0011] The present invention is further configured as follows: each group of the limiting sleeves is inserted into the inside of the installation through hole, an upper through groove is opened inside the limiting sleeve, and a lower through groove is opened at the bottom, a spring is sleeved on the outer wall of the lifting rod, and an abutment portion is set at the bottom, and a limiting ring is set on the side of the lifting rod close to the lower through groove.

[0012] The present invention is further configured as follows: the diameter of the limiting ring is larger than the diameter of the lower through groove, and the diameter of the abutting portion is matched with the diameter of the lower through groove.

[0013] By adopting the above technical solution, when it is necessary to relax the limiting effect of the lifting rod on the test sample (patch, patch), the lifting block can be lifted to drive the lifting rod to move upward relative to the limiting sleeve, so that the abutment portion relaxes the limiting effect; when it is necessary to limit the test sample (patch, patch), the lifting of the lifting block is relaxed, the lifting rod is reset under the action of the spring, and the abutment portion remains in abutment with the test sample (patch, patch).

[0014] The present invention is further configured as follows: a group of release levers are arranged on the inclined plate along its width direction, and the steel ball release mechanism includes a rotating part rotatably installed on the release lever, a fastening bolt arranged on the rotating part, and an annular ball supporting plate arranged on a side away from the fastening bolt.

[0015] The present invention is further configured as follows: the adjustment component includes a fixing frame installed on the inclined plate, an adjustment motor is installed inside the fixing frame, an output end of the adjustment motor is connected to a rotating swing rod, and an end of the rotating swing rod is connected to a rotating member.

[0016] By adopting the above technical solution, when the test steel ball needs to be released, the motor is adjusted to drive the rotating pendulum arm to rotate in the direction away from the inclined plate, and the rotating part and the annular ball holding plate are simultaneously driven to rotate away from the inclined plate; after the test steel ball is released, the motor is adjusted to drive the rotating pendulum arm to rotate in the direction close to the inclined plate, and the rotating part and the annular ball holding plate are simultaneously driven to re-fit with the direction of the inclined plate to complete the reset.

[0017] The present invention is further configured as follows: two groups of mounting frames are symmetrically arranged at the center position of the top of the base, a rotating rod is arranged between the two groups of mounting frames, and the inclined plate is rotatably mounted on the rotating rod.

[0019] The present invention is further configured as follows: an adjustment frame is arranged on the top of the base away from the collecting tank, a lifting slot is opened on the adjustment frame, and a limiting bolt that can pass through the lifting slot to fix the inclined plate is arranged on one side of the inclined plate.

[0020] The beneficial effects of the present invention are:

[0021] 1. Set up a fixed fixture instead of tape to limit the test sample (plaque, patch), and use a clamp instead of tape to limit the test sample (plaque, patch). This can not only avoid the test sample (plaque, patch) shifting during the test and causing errors in the test results, but also is simple and convenient to operate and can avoid damage to the device caused by cleaning tape residues.

[0022] 2. By setting up an adjustment component connected to the steel ball release mechanism, the adjusting motor and the rotating rocker arm are used to drive the rotating part and the annular ball holding plate to rotate around the release rotating rod, thereby replacing manual operation to complete the release of the test steel ball and the resetting of the annular ball holding plate, ensuring that the release speed and initial kinetic energy of the test steel ball are always consistent during each test, avoiding errors in the initial adhesion test results of the test sample (ointment, patch) due to inconsistent initial kinetic energy of the test steel ball.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the present invention in an illustrative manner, so it only shows the composition related to the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example 1, please refer to Figure 1-3 and Figure 6-9, a device for testing the initial adhesion of plasters and patches, comprising a base 1, an inclined plate 2 rotatably mounted on the base 1, a steel ball release mechanism 3 mounted on the inclined plate 2, and a fixing fixture 5. A test steel ball 6 can be placed inside the steel ball release mechanism 3. Before the test, the test sample (plaque, patch) is first fixed on the inclined plate 2 by the fixing fixture 5, and then the test steel ball 6 is released by the steel ball release mechanism 3. The initial adhesion test result of the test sample (plaque, patch) can be obtained according to the maximum ball size of the test steel ball 6 that the test sample (plaque, patch) can adhere to.

[0041] Please refer to Figure 1-2 and Fig. 9 The base 1 is arranged horizontally, and feet are arranged at the four corners of the base 1 to ensure the stability and reliability of the initial adhesion test device during use. A level bead is arranged on the top of the base 1. When in use, the level bead can be observed to determine whether the base 1 is in a horizontal state. If it is not horizontal, the height of the base 1 can be changed by adjusting the feet to keep it horizontal before use to avoid affecting the subsequent test results. Two sets of mounting frames 11 are symmetrically arranged at the center of the top of the base 1. The two sets of mounting frames 11 are arranged vertically on the top of the base 1 and are symmetrical about the longitudinal axis of the base 1. A rotating rod 12 is arranged between the two sets of mounting frames 11, and the inclined plate 2 is rotatably mounted on the rotating rod 12 and can rotate relative to the base 1.

[0042] Please refer to Figure 1-2 and Fig. 9 A collecting tank 13 is installed on one side of the top of the base 1. The collecting tank 13 is set as a rectangular structure with an open top. The collecting tank 13 is located on one side of the bottom of the inclined plate 2. After the test steel ball 6 slides down along the inclined plate 2, it can enter the collecting tank 13 for collection. A soft cushion made of a flexible material is arranged inside the collecting tank 13 to provide a buffer for the test steel ball 6 to avoid damage to the steel ball due to collisions that affects the initial adhesion test results. An adjustment frame 14 is arranged on the top of the base 1 away from the collecting tank 13. The adjustment frame 14 is arranged vertically on the top of the base 1. A lifting slot 15 is provided on the adjustment frame 14 to facilitate the adjustment of the height of the inclined plate 2.

[0043] Please refer to Figure 1-3, the inclined plate 2 is set to a rectangular structure, and a rotating hole 21 is opened on both sides of its bottom. The shape of the rotating hole 21 is adapted to the shape of the rotating rod 12. The inclined plate 2 is rotatably installed on the rotating rod 12 through the rotating hole 21, so that it can be rotated relative to the base 1 to adjust the inclination angle and height of the inclined plate 2. A reading grid that is convenient for reading can be set on the inclined plate 2, which is convenient for reading and judging the initial adhesion test results. A limiting bolt 22 is set on the side of the inclined plate 2 close to the adjustment frame 14, and the limiting bolt 22 passes through the lifting groove 15 to fix the inclined plate 2. After the angle adjustment of the inclined plate 2 is completed, the limiting bolt 22 can be passed through the corresponding position on the lifting groove 15 to limit the inclined plate 2 to ensure that the inclined plate 2 will not shift during the test. A group of release rotating rods 23 are set on the inclined plate 2 along its width direction, and the release rotating rods 23 are set on the top of the inclined plate 2 away from the collecting groove 13. A reading scale is provided on the inclined plate 2 , and the reading scale is located below the steel ball release mechanism 3 , so as to facilitate reading the run-up distance of the test steel ball 6 and the test result.

[0044] Please refer to Figure 2-4 The steel ball release mechanism 3 includes a rotating member 31 rotatably mounted on the release rotating rod 23, a fastening bolt 33 arranged on the rotating member 31, and an annular ball holding plate 34 arranged on a side away from the fastening bolt 33. A rotating groove 32 whose shape is adapted to the shape of the release rotating rod 23 is provided on the rotating member 31, and the rotating member 31 is rotatably mounted on the release rotating rod 23 through the rotating groove 32. The fastening bolt 33 is rotatably set on the rotating member 31, and the degree of loosening or tightening of the connection between the rotating member 31 and the release rotating rod 23 can be adjusted by the fastening bolt 33. A circular cavity is arranged inside the annular ball holding plate 34 for placing the test steel ball 6. Before the test, the side wall of the annular ball holding plate 34 is kept in contact with the side wall of the inclined plate 2, and the test steel ball 6 can be placed inside the annular ball holding plate 34 at this time. When conducting the test, the operator can rotate the fastening bolt 33 to release the rotating rod 23 to rotate the rotating part 31, thereby creating a gap between the inclined plate 2. The test steel ball 6 falls under the action of gravity and contacts the test sample (patch, patch), completing the initial adhesion test.

[0045] Please refer to Figure 3 and Figure 6-8 The fixing fixture 5 includes two sets of sliding guide rails 51 which are symmetrically arranged, and two sets of limiting sliders 52 are slidably installed on each set of sliding guide rails 51, and a set of clamping members 53 are installed on each set of limiting sliders 52. The limiting sliders 52 slide along the sliding guide rails 51, and the positions of the four sets of clamping members 53 can be adjusted, so that the four sets of clamping members 53 can be limited and fixed at the four corners of the test sample (ointment, patch).

[0046] Please refer to Figure 6The two sets of sliding guide rails 51 are symmetrically arranged about the longitudinal axis of the inclined plate 2, and each set of sliding guide rails 51 includes two sets of mounting members 513 arranged along the longitudinal direction of the inclined plate 2. The mounting members 513 are installed on the top of the inclined plate 2, and a sliding rod 515 is arranged between the two sets of mounting members 513, and the sliding rod 515 is arranged along the longitudinal direction of the inclined plate 2. The two sets of upper mounting members 513 are both provided with guide wheels 514, and a pulley 512 is sleeved between the two sets of guide wheels 514, and the pulley 512 is connected to the limit slider 52. One end of the pulley 512 is connected to a motor 511, and the motor 511 is installed on the bottom side wall of the inclined plate 2, and the output end is connected to the pulley 512. The motor 511 can drive the pulley 512 to rotate around the guide wheel 514. During the rotation of the pulley 512, it can synchronously drive the limit slider 52 to move along the length direction of the inclined plate 2, thereby adjusting the position of the limit slider 52 and the clamping member 53, so that the clamping member 53 can limit the test sample (ointment, patch) at the four corners.

[0047] Please refer to Figure 6 Each set of limit sliders 52 is provided with a slide groove 521 that matches the shape of the slide bar 515, and each set of limit sliders 52 is sleeved on the slide bar 515 through the slide groove 521, so that the limit sliders 52 can slide along the direction of the slide bar 515. Each set of limit sliders 52 is provided with a mounting through hole 522 on one side close to the center of the inclined plate 2.

[0048] Please refer to Figure 6-7Each set of clamping members 53 includes a limiting sleeve 536, a lifting rod 532 disposed inside the limiting sleeve 536, and a lifting block 531 disposed on the top of the limiting sleeve 536. Each set of limiting sleeves 536 is configured as a cylindrical structure whose diameter matches the shape of the mounting through hole 522, and each set of limiting sleeves 536 is plugged into the mounting through hole 522, thereby realizing the connection between the clamping member 53 and the limiting slider 52, so that the clamping member 53 can move synchronously with the limiting slider 52 to complete the position adjustment. An upper through groove 537 is provided inside the limiting sleeve 536, and a lower through groove 538 is provided at the bottom. The diameter of the upper through groove 537 is larger than the diameter of the lower through groove 538, and the upper through groove 537 and the lower through groove 538 are connected to each other. The lifting rod 532 passes through the upper through slot 537 and the lower through slot 538, and the top of the lifting rod 532 is inserted into the lifting block 531. By pressing or lifting the lifting block 531, the lifting rod 532 can be synchronously driven to move relative to the limiting sleeve 536. A limiting ring 533 is provided on the side of the lifting rod 532 close to the lower through slot 538, and an abutment portion 534 is provided at the bottom of the lifting rod 532. The diameter of the limiting ring 533 is larger than the diameter of the lower through slot 538, and the diameter of the abutment portion 534 is adapted to the diameter of the lower through slot 538. When the lifting rod 532 is inserted into the limiting sleeve 536, the limiting ring 533 abuts against the top of the lower through slot 538, and the abutment portion 534 can abut against the test sample (plaque, patch) placed on the inclined plate 2, thereby limiting the test sample (plaque, patch). A spring 535 is provided on the outer wall of the lifting rod 532. When it is necessary to relax the limiting effect of the lifting rod 532 on the sample (patch, patch), the lifting block 531 can be lifted to drive the lifting rod 532 to move upward relative to the limiting sleeve 536, so that the abutment 534 relaxes the limiting effect; when it is necessary to limit the sample (patch, patch), the lifting of the lifting block 531 is released, and the lifting rod 532 is reset under the action of the spring 535, and the abutment 534 maintains the state of abutting against the sample (patch, patch).

[0049] By moving the four groups of limit sliders 52 along the sliding guide rails 51, the four groups of clamping members 53 are synchronously driven to adjust the positions, so that the four groups of clamping members 53 can be limited from the four corners of the test sample (plaque, patch). Further, by pulling the lifting block 531, the lifting rod 532 is driven to move relative to the limiting sleeve 536, so that the abutment portion 534 and the test sample (plaque, patch) can be abutted or relaxed. After releasing the lifting block 531, under the action of the spring 535, the abutment portion 534 always maintains an abutment state with the test sample (plaque, patch), thereby limiting the test sample (plaque, patch). Using the clamping member 53 to replace the adhesive tape to limit the test sample (plaque, patch) can not only avoid the test sample (plaque, patch) displacement during the test process to cause errors in the test results, but also avoid the damage caused to the device by the cleaning adhesive tape residue.

[0050] Example 2, please refer to Figure 4-5 , although the problem of residues not being easy to clean caused by tape sticking the test sample (plaque, patch) can be effectively avoided by setting the fixing fixture 5, the initial adhesion test device is in use, and the steel ball release mechanism 3 is manually operated to complete the release of the test steel ball 6. During the manual control of the steel ball release mechanism 3, the release speed of the different test steel balls 6 will change due to manual errors, and the speed of the test steel ball 6 will further affect the initial kinetic energy of the test steel ball 6, which will eventually lead to errors in the initial adhesion test results of the test sample (plaque, patch). Therefore, it is necessary to set the adjustment component 4 to drive the steel ball release mechanism 3 to rotate and complete the release of the test steel ball 6, so as to ensure that the release speed and initial kinetic energy of the test steel ball 6 are always consistent.

[0051] Please refer to Figure 4-5 The adjustment component 4 includes a fixed frame 41 installed on the inclined plate 2. The fixed frame 41 is set as a rectangular frame structure and is installed on the bottom of the inclined plate 2 away from the fixed clamp 5. The fixed frame 41 is installed on the side of the inclined plate 2 close to the steel ball release mechanism 3, and an adjustment motor 42 is installed inside the fixed frame 41. The output end of the adjustment motor 42 is connected to a rotating pendulum 43, and the rotating pendulum 43 is rotatably installed on the fixed frame 41. The adjustment motor 42 can drive the rotating pendulum 43 to rotate. The end of the rotating pendulum 43 is connected to the rotating member 31. During the rotation of the rotating pendulum 43, the rotating member 31 can be synchronously driven to rotate relative to the release rotating rod 23. During the rotation of the rotating member 31 relative to the release rotating rod 23, the annular ball holding plate 34 can be separated from the inclined plate 2, thereby completing the release of the test steel ball 6.

[0052] Specifically, when the test steel ball 6 needs to be released, the rotating rocker arm 43 is driven by the adjusting motor 42 to rotate in the direction away from the inclined plate 2, and the rotating member 31 and the annular ball supporting plate 34 are simultaneously driven to rotate in the direction away from the inclined plate 2; after the test steel ball 6 is released, the adjusting motor 42 drives the rotating rocker arm 43 to rotate in the direction close to the inclined plate 2, and the rotating member 31 and the annular ball supporting plate 34 are simultaneously driven to re-fit with the direction of the inclined plate 2 to complete the reset.

[0053] By setting up the adjustment component 4, the adjustment motor 42 and the rotating rocker arm 43 are used to drive the rotating part 31 and the annular ball holding plate 34 to rotate around the release rotating rod 23, thereby replacing manual operation to complete the release of the test steel ball 6 and the resetting of the annular ball holding plate 34, ensuring that the release speed and initial kinetic energy of the test steel ball 6 remain consistent during each test, thereby avoiding errors in the initial adhesion test results of the test sample (patch, patch) due to inconsistent initial kinetic energy of the test steel ball 6.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front and back", "left and right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
