Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, and in particular to a testing device for rubber production. Background Technology

[0002] Sheet rubber serves as a fundamental raw material in numerous industrial sectors, including tire manufacturing, seal production, and pipeline corrosion protection. The uniformity of its thickness is a core quality indicator determining the performance of downstream products. For example, in tire production, excessive thickness deviations in the rubber sheet can lead to uneven stress on the tread, reducing tire lifespan. In seal processing, excessively thick rubber sheets can cause assembly jamming, while insufficient thickness can lead to seal failure. Therefore, real-time and accurate thickness detection during the production process after rubber sheet molding is crucial for intercepting substandard products and ensuring stable production quality.

[0003] Thickness inspection methods in the rubber production process are mainly divided into two categories: manual inspection and equipment inspection. Both methods have obvious technical defects. For example, manual inspection often uses tools such as calipers and micrometers for sampling measurement, which is inefficient. While automated inspection equipment relies on precision sensing technologies such as laser ranging and ultrasonic detection to achieve non-contact continuous inspection, the manufacturing and maintenance costs of such equipment are extremely high. The purchase cost of hundreds of thousands of yuan is difficult for small and medium-sized rubber production enterprises to bear. Utility Model Content

[0019] The outer surface of the mounting base 12 is provided with mounting holes 15. A pen 16 is movably connected to the inner surface of the mounting holes 15. A threaded rod 17 is threadedly connected to the inside of the mounting base 12. A rotating handle 18 is fixedly connected to the upper surface of the threaded rod 17. A rubber block 19 is fixedly connected to the lower surface of the threaded rod 17. A connecting plate 20 is fixedly connected to the upper surface of the connecting bracket 10. A writing paper 21 is fixedly connected to the left surface of the connecting plate 20 by double-sided tape. The first electrode plate 13 is electrically connected to the indicator light 23 through a wire. The second electrode plate 13 is electrically connected to the indicator light 23 through a wire.

[0020] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Working principle: During use, the produced sheet rubber is conveyed to the gap between the first pressure roller 3 and the limiting groove 4 through an external conveying device. When the thickness of the rubber sheet changes, it will squeeze the second pressure roller 6 to move upward. This will cause the square rod 7, the fixing plate 8, the fixing rod 11, and the mounting base 12 to move upward synchronously through the limiting block 5. This will cause the first electrode sheet 13 to separate from the second electrode sheet 14, thereby disconnecting the circuit connection with the indicator light 23 and turning off the indicator light 23. This will directly remind the staff that the thickness of the rubber sheet has changed. The range of thickness change of the rubber sheet can be determined by the length of the line drawn on the writing paper 21 by the pen 16 held by the mounting base 12. Finally, by measuring the height of the line, it can be quickly determined whether the thickness change of this batch of rubber sheets is within the quality range.
