Description

Technical Field

[0001] The utility model relates to the technical field of a paper bag feeding overheating fire prevention detection structure, in particular to a paper sheet overheating fire prevention control device of an iron wire machine. Background Art

[0002] At present, there is a kind of takeaway paper bag that has a built-in iron wire about 3cm below the bag opening. Taking advantage of the deformation and relative hardness of the iron wire, after the paper bag is opened, the bag opening can be folded down several layers to the iron wire position and the folded ends are clamped with the two ends of the iron wire to form a seal at the bag opening, so as to achieve the purpose of recycling the sealed bag opening twice or multiple times. When producing takeaway paper bags with iron wire, the production is basically completed by an iron wire machine; when the iron wire machine is in operation, the paper sheet needs to be transported to the heating position, the glue position in the paper sheet needs to be heated and softened, and then transported to the paper bag forming position to achieve the pasting of the paper sheet and the pasting of the built-in iron wire, etc., to complete the production of the iron wire takeaway paper bag. If the iron wire machine runs at an abnormal speed or feeds abnormally, paper jams (i.e., paper jams the heating position, causing paper jams, paper jams, etc.) or paper breaks may occur when the paper is fed to the heating position. This will easily cause the paper to be heated for a long time at the heating position, and then catch fire, which poses a great safety hazard. Therefore, it is very important to solve the safety hazard of paper heating. However, in the prior art, the structure of the iron wire machine does not have functions and components for detecting whether paper jams, paper breaks, etc. occur when the paper is fed and heated, and fails to effectively avoid the safety hazard of fire caused by paper jams.

[0020] Example 1

[0021] The paper sheet overheating fire prevention control device of the wire machine described in this embodiment 1 is as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a conveyor belt support 3 installed on the iron wire machine frame 1 for conveying paper pieces 2, a conveyor guide wheel 4 installed on the iron wire machine frame and in contact with the inner side of the conveyed paper piece to convey the paper piece in the opposite direction, a heating gun support 5 installed on the iron wire machine frame and located below the conveyor guide wheel and arranged corresponding to the glue position in the paper piece, and a heating gun 6 installed on the top of the heating gun support and arranged close to the glue position in the paper piece. The paper pieces used to produce takeaway paper bags are first conveyed into the heating component through the conveyor belt support. When the paper pieces enter the heating position, they are rolled and transported along the outer edge of the conveyor guide wheel. When the paper pieces pass through the conveyor guide wheel, the hot air outlet of the heating gun is aimed at the glue in the paper piece to heat and soften it, so as to realize the subsequent bag making, pasting and pasting of the paper pieces, etc.

[0022] The iron wire machine frame is also provided with a paper jam sensor 7 located at the paper feeding end of the conveying guide wheel and above the paper sheet for detecting whether the paper sheet is blocking the paper. When the paper sheet enters the paper feeding position of the conveying guide wheel and is blocked, the blocked paper sheets will overlap and clamp in the gap between the paper sheet and the paper feeding of the conveying guide wheel, resulting in increased thickness and blockage at this position. After the blocking sensor senses, a signal of abnormal paper jam can be sent to control the emergency stop of the entire iron wire machine equipment.

[0023] The iron wire machine frame is also provided with a temperature sensor 8 located between the conveying guide wheel and the heating gun and used to detect the surface temperature of the paper sheet. The temperature sensor arranged between the heating gun and the heating position of the conveying guide wheel can sense the heating temperature. If the heating temperature is abnormally overheated, the temperature sensor will send an abnormal overheating signal to control the emergency stop of the heating power supply and stop heating.

[0024] The iron wire machine frame is also provided with a color mark sensor 9 located just above the conveying guide wheel and used to detect the color mark on the top surface of the conveying guide wheel. When the paper sheet breaks due to abnormal feeding, the iron wire machine is in an empty running state, and no corresponding paper sheet enters the heating position and is output from the top of the conveying guide wheel. A color mark sensor is provided (because the paper sheet is the color of commonly used kraft paper, etc., the color mark sensor can easily identify whether there is a paper sheet) to sense whether there is a paper sheet output from the conveying guide wheel, judge whether there is a paper break and an empty running situation, and send an empty running signal to control the iron wire machine to stop when a paper break is found.

[0025] The paper jam sensor, temperature sensor and color mark sensor are separately connected to the controller 10 set on the iron wire machine frame. The signals sent by the three sensors are sent to the controller as input signals, and then the controller sends output signals to control the emergency stop of the iron wire machine and the emergency stop of the heating power supply.

[0026] In the first embodiment, the paper jam sensor is a photoelectric eye, but other sensors such as a distance sensor may also be used.

[0027] In this embodiment 1, the color mark sensor is a photoelectric sensor.

[0028] In this embodiment 1, the heating gun is a heating gun with a fan. The hot air generated when the heating gun is heated can be blown out by the built-in fan to the position where the glue is softened; in addition, the built-in fan can be controlled by the output signal of the controller to provide normal temperature wind to quickly cool down the heating gun to avoid overheating of the heating gun.

[0029] In this embodiment 1, the heating end of the heating gun is provided with an air outlet seat 11 with an air outlet, and the air outlet seat is an arc-shaped air outlet seat arranged corresponding to the arc surface line of the conveying guide wheel. The glue is softened by arranging the air outlet seat at the air outlet end of the heating gun and using the air outlet to blow hot air to the glue position of the paper sheet.

[0030] In this embodiment 1, the heating gun is located below the conveying guide wheel and the air outlet seat is tilted upward and faces the conveying guide wheel.

[0031] In this embodiment 1, the paper overheating fire prevention control device of the iron wire machine avoids the hidden danger of paper fire caused by abnormal operation of the iron wire machine; by setting a temperature sensor at the heating part of the iron wire machine to sense the heating temperature, and setting a paper jam sensor before entering the heating to sense whether there is paper jam and setting a color mark sensor at the paper output position after heating to sense and judge whether the paper is broken and cause the iron paper machine to run empty, these sensors can provide signals to the control part, and can automatically stop and cool down in the case of overheating, thereby avoiding overheating and causing paper fire and then causing fire.

[0032] The above is only a preferred embodiment of the utility model, and does not limit the structure of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
