Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production technology, and in particular to a high-efficiency impregnation equipment for impregnated paper. Background Technology

[0002] Impregnation is a process in which base paper is immersed in an impregnation solution. During its movement within the solution, the paper is saturated with the impregnation liquid, improving its protective properties such as oil resistance, water resistance, moisture resistance, abrasion resistance, and insulation. Existing impregnation processes mainly consist of three stages: pre-impregnation, impregnation, and pressing. Pre-impregnation removes air from the base paper, accelerating impregnation efficiency. Impregnation saturates the paper. Pressing removes excess impregnation liquid. These three processes complete the impregnation of the paper.

[0003] Existing impregnation equipment mainly includes a pre-impregnation tank, an impregnation tank, and a pressing device; however, it has the following shortcomings:

[0004] 1. Existing pre-impregnation methods mainly use floating and scraper methods. In the floating pre-impregnation method, the paper is floated on the paper and impregnated on one side. During impregnation, due to the consumption of impregnation liquid, the level of impregnation liquid may be lower than that of the paper, resulting in uneven pre-impregnation or lack of pre-impregnation process, which leads to reduced impregnation efficiency.

[0005] 2. The existing impregnation tank is a single tank, and impregnation is achieved by injecting impregnation liquid into the tank. However, it should be noted that the invasiveness of the impregnation liquid is related to the thickness of the base paper. For thicker paper, impregnation is easier, but the impregnation process takes longer and the resistance is greater. For impregnated paper of different thicknesses, the impregnation time should be adjusted. For thicker paper, multiple entries into the impregnation tank are required, resulting in low impregnation efficiency.

[0006] 3. The impregnation liquid in the existing impregnation tank does not flow, and the impregnation liquid density in the impregnation tank is relatively high and the settling velocity is relatively large, which makes it easy to deposit at the bottom, resulting in turbidity of the impregnation liquid and reduced impregnation efficiency.

[0007] Therefore, how to design a high-efficiency impregnation equipment for impregnated paper that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0008] To address the aforementioned problems, the present invention aims to provide a high-efficiency impregnation device for impregnated paper, which solves the problems of existing impregnation devices being unable to flexibly adjust according to the impregnation time required for the impregnated paper, and the impregnation solution being relatively turbid due to the lack of liquid flow in the tank, thus reducing impregnation efficiency.

The bottom end of the pull rope passes through the top wall of the immersion machine body and is fixedly connected to the connecting rod.

[0018] Furthermore, a water outlet is provided on the side wall of the impregnation machine corresponding to the liquid recovery tank. The water circulation assembly includes a liquid supply device located outside the impregnation machine and connected to the pre-impregnation chamber via a water inlet pipe, a water pump located outside the impregnation machine, a filter located outside the impregnation machine and connected to the water pump, and a first water pipe, a second water pipe, and a third water pipe connected to the filter.

[0024] This utility model has the following beneficial effects:

[0025] 1-This utility model is equipped with an impregnation device. According to the thickness of the impregnated paper and the required impregnation time, the height of each impregnation component can be adjusted by the drive device. This increases the vertical gap between the third guide rollers of the impregnation components, increases the time for the impregnated paper to pass through the impregnation tank, thereby reducing the number of impregnation cycles and increasing impregnation efficiency. At the same time, the immersion height of the impregnated paper in the impregnation tank can be flexibly adjusted (because the water pressure of the impregnation liquid at the bottom of the impregnation tank is greater than that at the top of the impregnation tank). This allows thinner and easier-to-impregnate impregnated paper to be impregnated at the top of the impregnation tank, while thicker and more difficult-to-impregnate impregnated paper is impregnated at the bottom of the impregnation tank. This design offers high flexibility and strong practicality.

[0026] 2- This utility model is equipped with a pre-impregnation device and a liquid level sensor. The position of the first guide roller on the moving plate is controlled by the upward or downward movement of the cylinder, so that the impregnated paper sheet passing under the first guide tube is kept floating on the liquid surface as much as possible, which meets the requirements of impregnated paper pre-impregnation, completes the pre-impregnation, and improves the impregnation efficiency.

[0027] 3- This utility model is equipped with a water circulation component. By setting the height of the first water platform, the second water platform and the third water platform to gradually decrease, the pre-impregnation chamber, the impregnation tank and the liquid recovery tank are in a stepped shape. This allows the impregnation liquid in the pre-impregnation chamber to flow naturally into the impregnation tank from the first drain outlet under the action of gravity. The impregnation liquid in the impregnation tank flows naturally into the liquid recovery tank from the second drain outlet under the action of gravity. The impregnation liquid is circulated as much as possible by a water pump and a filter, so as to maintain the water circulation of the impregnation liquid as much as possible and save impregnation liquid.

[0028] 4- This utility model is equipped with a water circulation component, including a first water pipe, a second water pipe, and a third water pipe, and a first water outlet nozzle connected to the second water pipe and a second water outlet nozzle connected to the third water pipe; on the one hand, it is used to spray impregnation liquid onto the impregnated paper so that the impregnation liquid water molecules adhere to the surface of the impregnated paper before it is impregnated, and on the other hand, it increases or decreases the humidity of the liquid in the pre-impregnation chamber to accelerate the impregnation efficiency of the impregnated paper.

[0049] Furthermore, a water outlet 19 is provided on the side wall of the impregnation machine body 1 at the position corresponding to the liquid recovery tank 18. The water circulation assembly 2 includes a liquid supply device 21 laid outside the impregnation machine body 1 and connected to the pre-impregnation chamber through a water inlet pipe, a water pump 22 fixed outside the impregnation machine body 1, a filter 23 fixed outside the impregnation machine body 1 and connected to the pre-pump 22, and a first water pipe 24, a second water pipe 25, and a third water pipe 26 connected to the filter 23. The first water pipe 24 is laid on the impregnation machine body 1 and its outlet extends through the side wall of the impregnation machine body 1 to the bottom of the pre-impregnation chamber 16. The second water pipe 25 is laid on the side wall of the impregnation machine body 1 at the position corresponding to the pre-impregnation chamber 16. The third water pipe 26 is laid on the top position of the impregnation machine body 1 at the position corresponding to the pre-impregnation chamber 16. The filter 23 is connected to the main water pipe and four-way connector (not shown in the figure) between the first water pipe 24, the second water pipe 25 and the third water pipe 26. Water is supplied to the pre-impregnation chamber through the external liquid supply device 21. Since the height between the first water platform 11, the second water platform 12 and the third water platform 13 gradually decreases, the pre-impregnation chamber and the impregnation tank 17 and the liquid recovery tank 18 are in a stepped shape. The impregnation liquid is discharged through the first drain outlet 142 and overflows at the first impregnation paper through hole 141. The liquid flows into the impregnation tank 17, then overflows from the second drain outlet 152 and the second impregnation paper through-hole 151 into the liquid recovery tank 18 (the liquid recovery tank 18 also contains the impregnation liquid discharged when the impregnation paper passes through the pressing device 5). The impregnation liquid in the liquid recovery tank 18 is drawn out by the water pump 22 at the bottom of the liquid recovery tank 18, filtered by the filter 23 under the action of the water pump 22, and then sent into the first water pipe 24, the second water pipe 25, and the third water pipe 26 respectively. The first water pipe 24 is placed at the bottom of the pre-impregnation chamber to replenish the impregnation liquid in the pre-impregnation chamber.

The first water nozzles 251 pass through the side wall of the impregnation machine body 1 and are located in the pre-impregnation chamber 16. The third water pipe 26 is connected to a plurality of second water nozzles 261 on its side wall. The second water nozzles 261 pass through the top of the impregnation machine and are located in the pre-impregnation chamber 16. On the one hand, they are used to spray impregnation liquid onto the impregnated paper so that the surface of the impregnated paper is covered with impregnation liquid water molecules before impregnation. On the other hand, they increase or decrease the humidity of the liquid in the pre-impregnation chamber and accelerate the impregnation efficiency of the impregnated paper.

[0051] Furthermore, a liquid level sensor 161 for detecting the water level is fixed inside the pre-impregnation chamber 16. The liquid level sensor 161 detects the height of the impregnation liquid level in the pre-impregnation chamber 16. The liquid level sensor 161 outputs a corresponding control signal through the control module to control the cylinder 322. The cylinder 322 moves up or down to control the position of the first guide roller 313 on the moving plate 312, so that the impregnated paper sheets passing below the first guide tube are kept floating on the liquid surface as much as possible, which meets the requirements for impregnation of impregnated paper.

The second drive motor 51 causes the lead screw 52 to rotate. When the lead screw 52 rotates, it drives the first connecting sleeve 53 and the second understanding sleeve at both ends to move towards or away from each other, so that the first extrusion roller 55 and the second extrusion roller 56 are close to or far apart according to the thickness of the impregnated paper and the impregnation requirements.

[0053] Furthermore, an impregnation paper inlet 101 is provided on the impregnation machine body 1 at the position corresponding to the pre-impregnation chamber 16, and an impregnation paper outlet 102 is provided on the impregnation machine body 1 at the position corresponding to the liquid recovery tank 18.

[0054] The working principle is roughly as follows:

[0055] like Figure 3 As shown, the impregnated paper enters the pre-impregnation chamber 16 through the impregnated paper inlet 101, passes under the two first guide rollers 313 in sequence to complete the pre-impregnation process, enters the impregnation tank 17 through the second guide roller 1411, passes between the third guide rollers 413 to complete the impregnation process, enters the liquid recovery tank 18 through the fourth guide roller 171, moves upward through the fifth guide roller 181, passes between the first squeeze roller 55 and the second squeeze roller 56, the distance between the first squeeze roller 55 and the second squeeze roller 56 is adjusted by the pressing device 5 so that the impregnated paper is pressed between the first squeeze roller 55 and the second squeeze roller 56 to squeeze out excess impregnation liquid, and finally moves out from the impregnated paper outlet 102.
