Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a rolling wheel device. Background Technology

[0002] During the production process, adhesive tapes require accurate testing of various properties to ensure product quality meets standards and user requirements. For example, peel strength and tack are important indicators for evaluating tape performance. Before conducting these performance tests, the tape must be adhered to a test substrate at standard pressure and speed to prepare test specimens that meet the testing requirements.

[0003] Early tape testing used manual roller devices, where operators manually rolled the tape with the rollers. This method was not only inefficient but also highly susceptible to human error, making it difficult to guarantee the stability and accuracy of test results. With technological advancements, electric roller devices gradually emerged and became widely used. Electric roller devices are electrically driven, automatically controlling the speed and pressure of the rolling rollers. This not only improves testing efficiency but also ensures the stability and consistency of the rolling process, reducing human interference and improving the reliability of test results. As tape technology continues to develop, various types and applications of tapes have emerged, such as pressure-sensitive tapes, hot-melt tapes, and double-sided tapes. Different types of tapes have different performance characteristics and testing requirements. Current electric roller devices often only test a single type of tape, failing to meet the testing needs of multiple tape types, directly impacting the degree of automation and work efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Please see Figure 1 This application provides a rolling wheel device, including: a housing 10 and a rolling mechanism 20 disposed inside the housing 10; the rolling mechanism 20 includes a power component 21, a rolling component 23 and a connecting member 22. The power component 21 is provided with a linear motion module 212. One end of the connecting member 22 is fixedly connected to the output end of the linear motion module 212 and the other end is fixedly connected to the rolling component 23. The linear motion module 212 drives the connecting member 22, thereby pushing the rolling component 23 to move.

[0035] Please see Figure 1-3 Furthermore, the rolling assembly 23 is provided with a roller group 231, which includes a rolling roller 2311 for direct rolling and pressing, and counterweights 2312 detachably connected to both ends of the rolling roller 2311 along its axial direction. By providing detachable counterweights 2312, the rolling pressure can be easily increased or decreased. The rolling roller 2311 is movably positioned above the test specimen plate, and the tape is directly rolled by the rolling roller 2311 to evenly adhere the tape to the test specimen plate, thus obtaining the test specimen.

[0036] Specifically, in this embodiment, the rolling wheel 2311 has rollers protruding at both ends along its axial direction, and the rollers have threaded holes along their axial direction; the counterweight 2312 has a screw that engages with the threaded holes to be fixed to both ends of the rolling wheel 2311, and can move synchronously with the rolling wheel 2311. In other embodiments, the rolling wheel 2311 and the counterweight 2312 can be fixed in other ways, and are not limited thereto.

[0037] Furthermore, in some embodiments, the rolling assembly 23 is further provided with a roller frame 232; the roller frame 232 is fixedly connected to the connector 22, and the roller frame 232 is provided with a slot, in which the roller is movably embedded, so that the roller frame 232 supports the roller assembly 231 and drives the roller assembly 231 to move synchronously. Specifically, the roller is provided with a bearing 2313, which is embedded in the slot, so that the rolling wheel 2311 can rotate relative to the roller frame 232, so as to further realize the rolling of the conveyor belt by the rolling wheel 2311.

[0038] Please see Figure 1-5 Furthermore, in some embodiments, the housing 10 is provided with a base 11, an outer shell 12, and a movable cover plate 13. The outer shell 12 and the base 11 enclose a first chamber 15, and the power component 21 is disposed in the first chamber 15. The outer shell 12 and the movable cover plate 13 enclose a second chamber 16, and the rolling component 23 is disposed in the second chamber 16. By separating the power component 21 and the rolling component 23 in two chambers, it is possible to avoid the dust caused by the operation of the power component 21 adhering to the tape, affecting the adhesion effect of the tape, and causing instability of the test specimen.

[0039] Specifically, the outer casing 12 is provided with a partition 121, which is disposed between the first chamber 15 and the second chamber 16. The partition 121 has a sliding hole 1211. One end of the connector 22 is connected to the linear motion module 212, and the other end passes through the sliding hole 1211 and is fixed to the roller frame 232 to drive the roller assembly 231 to move. This arrangement can effectively prevent the airflow in the first chamber 15 from interfering with the air in the second chamber 16 and affecting the quality of the specimen.

[0040] Furthermore, in some embodiments, the housing 12 also includes a dust curtain covering the sliding hole 1211 to further prevent dust in the first chamber 15 from entering the second chamber 16 and affecting the specimen, thereby further improving the cleanliness of the second chamber 16 and preventing dust from adhering to the specimen plate or tape, affecting the adhesion performance between the tape and the specimen plate, and affecting the results of subsequent tape performance tests.

[0041] Furthermore, in some embodiments, one end of the movable cover 13 is rotatably connected to the outer casing 12, and the other end is movably abutted against the outer casing 12. The movable cover 13 is used to seal the second chamber 16, preventing dust from outside the device from entering the second chamber 16 during the operation of the rolling assembly 23. As an example, the movable cover 13 is rotatably connected to the outer casing 12 via a hinge, allowing the movable cover 13 to rotate and open relative to the outer casing 12. In addition, the movable cover 13 is also equipped with a cylinder 131, one end of which is rotatably connected to the movable cover 13, and the other end of which is rotatably connected to the outer casing 12. This cylinder supports the movable cover 13 when it is open, and simultaneously closes the movable cover 13 to the outer casing 12 through the action of the cylinder 131.

[0042] Furthermore, a first proximity switch 122 is provided at the contact point between the outer casing 12 and the movable cover plate 13 to sense whether the movable cover plate 13 is closed with the outer casing 12. Only when the movable cover plate 13 is closed with the outer casing 12 can the rolling assembly 23 perform the rolling operation, thereby preventing external people or objects from affecting the rolling operation and improving the safety of the operation.

[0043] Furthermore, in some embodiments, the rolling mechanism 20 further includes a support assembly 24 disposed within the second chamber 16 for supporting the specimen plate.

[0044] Specifically, the support assembly 24 includes a track plate 242, a variable speed steel plate 243, and a clamping plate 244. The track plate 242 is parallel to the linear motion module 212 and horizontally fixed below the rolling roller 2311, so that the rolling roller 2311 can be driven by the linear motion module 212 to roll the specimen plate along the length of the track plate 242. The clamping plate 244 is movably disposed in the middle of the track plate 242, and a recessed sample groove is provided in the middle, in which the specimen plate is placed. Finger positions are provided on both sides of the sample groove to facilitate the placement or removal of the specimen by the operator.

[0045] Specifically, the variable-speed steel plate 243 is fixed at both ends of the track slab 242 along its length. At the beginning of a single pass, the rolling wheel 2311 passes through the variable-speed steel plate 243 and can reach a stable rolling speed in a short time. This ensures that the tape adheres to the specimen material under relatively stable pressure and speed, avoiding insufficient or uneven adhesion between the tape and the specimen material due to unstable initial speed, which would affect the accuracy of subsequent peel force or holding force test results. At the end of a single pass, the variable-speed steel plate 243 allows the rolling wheel 2311 to decelerate smoothly until it stops, preventing the rolling wheel 2311 from continuing to roll due to inertia and causing additional stretching or friction on the tape and specimen material. This ensures that the rolling operation is completed under the specified stroke and conditions, improving the repeatability and reliability of the test results. In this way, during multiple round trips of rolling the tape, the rolling wheel 2311 can be guaranteed to roll the tape and specimen material at a uniform speed and smoothly, thereby improving the accuracy of sample preparation.

[0046] Furthermore, in some embodiments, the support assembly 24 is also provided with a support plate 241, which is fixed to the outer shell 12, and the runway plate 242 is fixed on the support plate 241.

[0047] Furthermore, a perforation is provided below the support plate 241, and the support plate 241 has a through hole 2411. In conjunction with this, the housing 10 is also provided with a movable, pull-out tray 14, located below the support plate 241. The tray 14 is used to collect and support test specimens and waste, while providing a stable support platform for test specimen preparation, ensuring that the test specimens do not shake or shift when the rolling wheel 2311 is used for rolling, thus guaranteeing the accuracy of the test results.

[0048] Furthermore, in some embodiments, the linear motion module 212 is a lead screw with a linear guide rail, and the power assembly 21 is also equipped with a motor 211. The rotation of the motor 211 drives the lead screw to rotate, thereby driving the connecting member 22 and the roller assembly 231 to move synchronously. It is understood that the connection between the motor 211 and the lead screw can be through a synchronous belt or a coupling, or other transmission methods can be used to control the operation of the lead screw through the motor 211, and is not limited thereto. In other embodiments, the linear motion module 212 can also be a pneumatic linear motion module or other components that can drive the roller assembly 231 to reciprocate, which will not be described in detail here.

[0049] Furthermore, in some embodiments, the power assembly 21 further includes a second proximity switch 213, which is disposed near the end of the linear motion module 212 to sense the operating state of the linear motion module 212 and record the reciprocating stroke of the linear motion module 212.

[0050] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0051] (1) Removable counterweights are installed at both ends of the roller axial direction to accommodate different types of conveyor belts, ensuring the stability of the device operation and improving the automation level and work efficiency of the test;

[0052] (2) By separating the power assembly and the rolling assembly into two chambers, the environment for making the test specimen is guaranteed, and dust and other factors are avoided from affecting the test specimen, thereby affecting the stability of the test specimen and the accuracy of the test.

[0053] (3) By setting a proximity switch at the contact point between the outer shell and the movable cover, the safety and stability of the specimen fabrication can be improved by sensing whether the movable cover is closed.

[0054] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
