Description

Technical Field

[0001] The utility model relates to the technical field of internal mixing film drying equipment, in particular to a device for detecting and adjusting the drying degree of internal mixing film. Background Art

Before storage, it needs to pass through a release agent pool to prevent the rubber from sticking to each other and being unable to be processed, and then the mixed film is blown dry by a blowing device. However, the drying equipment in the prior art lacks a detection and adjustment device, and it is impossible to judge the degree of drying of the mixed film, which will cause the following problems: the release agent is not blown dry, and the mixed film with moisture is used in the subsequent process, resulting in bubbles in the finished product after vulcanization; the blowing device continues to work after the release agent is dried, resulting in energy waste. Utility Model Content

[0003] The utility model aims to provide a detection and adjustment device for the drying degree of a mixed film, aiming to solve the technical problem that the prior art lacks a detection and adjustment device and cannot judge the drying degree of the mixed film.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

The detection roller and the support roller are rotatably mounted on a machine body. A plurality of moisture detection elements are mounted on the detection roller. The moisture detection elements are connected to controller signals. The controller can control the conveying speed of a film conveying device.

[0006] With the above structure, the detection roller is pressed on the surface of the mixed film and rolls synchronously with the sealing film. The moisture detection element on the detection roller detects whether there is moisture on the mixed film, thereby testing whether the mixed film is dried by the blowing device. The conveying speed of the film conveying device can be adjusted according to the detected dryness, thereby improving efficiency and avoiding energy waste.

[0007] Preferably, the moisture detection element is a humidity-sensitive resistor installed on the detection roller, and the dryness of the mixed film is detected by the humidity-sensitive resistor.

When the moisture detection element on the detection roller rotates to the front with the detection roller, the nozzle sprays hot air to the moisture detection element to dry the moisture detection element, thereby preventing the moisture on the moisture detection element from interfering with subsequent detection results.

[0010] Preferably, the nozzles are arranged in one-to-one correspondence with the mounting openings, which can improve the drying efficiency.

[0011] Preferably, a conical portion is provided on the mounting opening, the outer diameter of the conical portion is gradually expanded toward the mounting opening, a cavity is provided on the conical portion, and an inlet connected to the cavity is provided at the conical portion at the conical end. The conical portion can pierce the mixed film to detect the moisture in the middle of the mixed film.

[0012] Preferably, a pressing roller located in front of the detection roller is rotatably mounted on the machine body. The arrangement of the pressing roller can prevent the mixed film from being lifted up by the conical portion, thereby affecting the conveyance of the mixed film.

[0013] Preferably, the probe of the moisture detection element extends into the inlet. The probe of the moisture detection element extends into the inlet, which can improve the accuracy of the detection result.

[0014] Preferably, the side wall of the conical portion is provided with a plurality of air inlets connected to the cavity, and the detection roller is provided with a plurality of air outlets. The provision of the air inlets can facilitate the outside wind or the hot air blown out by the nozzle to enter the cavity to dry the moisture detection element, and the provision of the air outlets allows the gas in the detection roller to circulate, which is convenient for the moisture detection element to be naturally dried or blown dry.
