Description

Technical Field

[0001] The utility model relates to a thickness detection device for the production of cream tissue paper, belonging to the technical field of tissue paper production equipment. Background Art

[0002] Existing tissue papers are generally constructed with a thickness of 3 - 5 layers. During the production process of tissue papers, the tissue papers are formed by single - layer lamination, and processing defects such as missing layers may occur during this period. For example, for a finished product that requires a three - layer tissue paper thickness, only two layers are made. To solve the above problems, the common detection method is to manually take out the made tissue papers for spot checks to make a judgment by humans, but this method has the situation of missed inspections.

[0003] Chinese Utility Model Patent No. 2020227815115 discloses a thickness detection device for tissue paper production, including a frame. A conveyor belt for conveying tissue paper is arranged on the frame. An upper frame body is arranged on the frame. The conveyor belt is placed below the upper frame body. A number of light sensors are arranged in a row on the upper frame body. A number of LED lights for irradiating the tissue paper are buried in the conveyor belt. The light sensors are connected to a computer. An alarm is also arranged on the upper frame body. In the utility model, the light passing through the tissue paper irradiated by the LED lights will be sensed by the light sensors, and the light sensors will transmit the information of the light intensity to the computer. The computer obtains the light data and concludes that the thickness of the tissue paper does not meet the standard, and issues an alarm through the alarm to remind the staff.

[0004] This device has deficiencies. That is, when a cream coating is applied to the surface of the tissue paper, it will affect the irradiation of light, resulting in detection failure. To solve this deficiency, our enterprise sets up a thickness detection device for the production of cream tissue paper on the existing processing production line. Content of the Utility Model

[0005] The purpose of the utility model is to provide a thickness detection device for the production of cream tissue paper to solve the above problems.

[0006] The technical solution adopted by the utility model is: a thickness detection device for the production of cream tissue paper, including a fixed profile connected to production equipment, a fixed block installed on the top of the fixed profile, and a fixed frame installed on the top of the fixed block;

[0007] An encoder is installed on the fixed frame. The rotating shaft of the encoder is connected to a rubber wheel. The rubber wheel is in contact with the upper part of a sliding shaft. The axis of the sliding shaft faces the tissue paper conveying direction;

[0008] The lower part of the sliding shaft is connected to a clamping block. The push rod of a cylinder penetrates through the clamping block and is connected to the top of the wheel frame of a pressure wheel. The push rod of the cylinder is arranged parallel to the sliding shaft;

[0009] The upper part of the sliding shaft is in sliding fit with the fixed block;

[0010] The cylinder block of the cylinder is installed on the front side of the fixed profile.

[0011] Beneficial effects:

[0012] This device can automatically detect the thickness of the tissue paper coated with a cream coating. When the tissue paper is transported below the detection device, the pressing wheel presses downwards. During the downward movement of the pressing wheel, it drives the rubber wheel fixed on the encoder to roll. During the rolling process, the encoder is linked to feedback data, thereby realizing on-line thickness monitoring. Description of the drawings
