Description

Technical Field

[0001] This utility model relates to the field of paper feeding device technology, and more specifically to a paper feeding device for a glue applicator. Background Technology

[0002] In the papermaking industry, the main function of a sizing machine is to prevent liquid penetration, achieve better surface properties, and improve the physical properties of the paper, such as increasing surface strength, internal bonding strength, transverse ring crush index, and longitudinal breaking length. Simultaneously, the adhesive also enhances the bonding strength between fibers and the paper's density. In other industries, such as textiles, liquid adhesives can be applied to textile surfaces; in the electronics industry, electronic adhesives can be applied, potted, or dripped, enabling products to perform bonding, insulation, and fixing functions. The paper feeding device of the sizing machine smoothly guides the paper from the unwinding device or the previous process to the sizing section of the sizing machine, ensuring the paper accurately enters the machine for the sizing operation, preventing paper deviation, skewing, or folding, and guaranteeing the uniformity and quality of the sizing.

[0003] For example, a paper feeding device for a sizing machine, disclosed in prior art (CN214938795U), is equipped with a buffer assembly. The paper is sequentially and alternately wound onto multiple guide rollers. A motor is started to drive the guide rollers to rotate. During the paper feeding process, when the pressure is too high, the slider can drive the guide rollers to slide along the slide bar through the connecting frame and exert a force on the spring. The spring can buffer the impact force, giving the guide rollers a certain buffer space. This can prevent the paper from breaking due to excessive tension or high paper feeding speed during the paper feeding process, making it highly practical.

[0004] However, the existing technology described above still has the following problems in use: dust, lint, and other impurities from the environment will adhere to the paper surface. If not treated in time, these impurities will cause the sizing surface of the paper to be uneven, affecting the sizing quality. Based on this, the present invention provides a paper feeding device for a sizing machine with a cleaning function. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a paper feeding device for a sizing machine. By integrating cleaning and correction functions within the paper feeding box, it can automatically clean impurities from the upper and lower surfaces of the paper, preventing impurities from adhering to the paper and affecting the subsequent sizing quality. By adjusting the paper direction with the help of the first and second paper feeding rollers, the paper can be smoothly, accurately, and cleanly fed between the upper and lower sizing rollers, ensuring production continuity, improving sizing quality and production efficiency, and thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper feeding device for a sizing machine, comprising a paper feeding box, wherein the paper feeding box has a cleaning chamber and a correction chamber connected front and back, the top and bottom walls of the cleaning chamber are provided with brush rollers, the top and bottom walls of the correction chamber are provided with two first paper feeding rollers, and the two sides of the correction chamber are provided with second paper feeding rollers, each brush roller, each first paper feeding roller and each second paper feeding roller is movably provided with a first support, each first support is connected to the paper feeding box through an adjustment mechanism, and the top and bottom walls of the cleaning chamber are fixedly provided with dust suction heads, and the two dust suction heads are connected to a dust suction device.

[0007] In a preferred embodiment, each adjustment mechanism includes a first electric push rod that passes through the paper feed box and is fixed to a first bracket.

[0008] In a preferred embodiment, the vacuuming device includes an industrial vacuum cleaner, which is located on one side of the paper feed box. The suction port of the industrial vacuum cleaner is connected to two suction heads through a three-way pipe. A shock-absorbing base is fixedly provided at the bottom of the industrial vacuum cleaner. By setting the shock-absorbing base, vibration and noise can be reduced, and it can also play a buffering and isolation role between the industrial vacuum cleaner and the ground, reducing the hard impact and friction between the vacuum cleaner and the ground, thereby reducing the impact of vibration on paper conveying.

[0009] In a preferred embodiment, a motor is fixed to one end of each of the two brush rollers. The motor is fixed on the first support of the brush roller, and the brush roller is automatically rotated by the motor, thereby improving the cleaning effect.

[0010] In a preferred embodiment, the paper feed box includes an upper box body and a lower box body, and a rubber sealing strip is provided between the upper box body and the lower box body to fill the gap between them. The rubber sealing strip can improve the firmness between the upper box body and the lower box body.

[0011] In a preferred embodiment, the correction cavity is provided with an upper glue roller and a lower glue roller. A second bracket is movably mounted on both the upper and lower glue rollers. Both second brackets are connected to the paper guide box via a second electric push rod. The second electric push rod drives the second brackets to move, thereby facilitating the adjustment of the distance between the upper and lower glue rollers and the paper.

[0012] In a preferred embodiment, a support frame is fixedly provided at the bottom of the lower box, and shock-absorbing pads are fixedly provided at the four corners of the bottom of the support frame.
