Description

Technical Field

[0001] The utility model relates to the technical field of carbon paper impregnation equipment, in particular to an impregnation device for carbon paper used in batteries. Background Art

[0002] During the production process of chopped carbon fiber impregnated with resin, since carbon fiber itself is an inert material with low molecular activity and poor bonding ability with resin, it is not easy to be fully infiltrated by the resin matrix. It is necessary to extend the infiltration time to achieve the purpose of fully infiltrating the carbon paper with resin. In addition, when the carbonized carbon paper is impregnated with PTFE emulsion, the emulsion cannot completely enter the interior of the material in a short time, which has a great impact on the performance of the material.

[0003] The existing technical solution needs to adjust the impregnation time by increasing or decreasing the production speed, which greatly restricts the production capacity of the equipment; this method has high requirements on material strength, and the metering method after impregnation has the defect of secondary surface pollution; it is difficult to meet the production requirements of full impregnation of carbonized carbon paper; it completely relies on the material to absorb the impregnation liquid independently, and cannot cause the liquid to quickly enter the material; as the production time increases, bubbles will accumulate on the top of the liquid, and the bubbles that have not burst will adhere to the surface of the carbon fiber and affect the distribution of the resin. For this reason, we propose an impregnation device for carbon paper for batteries.

[0004] The prior art has the following problems:

[0005] 1. The current carbon paper impregnation device needs to adjust the impregnation time by increasing or decreasing the production speed, which greatly restricts the production capacity of the equipment;

[0009] A hydraulic lifting mechanism is also provided inside the rear end of the equipment body, and a No. 1 roller is also provided on one side of the upper inner end of the equipment body, and an introduction end facing roller is provided below the No. 1 roller, and a No. 2 roller is provided obliquely below the introduction end facing roller, and a first driven combination roller is provided obliquely above the No. 2 roller, and a second driven combination roller is provided on the horizontal right side of the first driven combination roller, and a horizontal guide roller is provided on the oblique lower side of the second driven combination roller, and a horizontal driven roller is provided on the horizontal right side of the horizontal guide roller, and a first active combination roller is provided on the oblique upper side of the horizontal driven roller, and a second active combination roller is provided on the horizontal right side of the first active combination roller, and an output end driven roller is provided on the oblique lower side of the second active combination roller, and an output end guide roller is provided on the oblique upper side of the output end driven roller, and an output end facing roller is provided vertically above the output end guide roller;

[0010] The hydraulic lifting mechanism also includes a hydraulic column and a linkage block. The hydraulic column is movably connected to the hydraulic lifting mechanism through a sliding connection, and the linkage block is fixedly connected to the top of the hydraulic column through a fixed installation.

[0011] As a preferred technical solution of the present utility model, the device body also includes a height adjustment groove and a sealed back cover. The height adjustment grooves are provided in two groups and are opened on the internal end surface of the device body. The sealed back cover is fixedly connected to the rear end of the device body through fixed installation.

[0012] As a preferred technical solution of the utility model, the opposing rollers at the inlet end and the opposing rollers at the output end are composed of a dual-axis structure, the carbon paper moves from the internal gap, the first driven combination roller and the second driven combination roller and the first active combination roller and the second active combination roller are combination rollers, and their heights are kept uniform through linkage blocks respectively, and the rear ends of the opposing rollers at the output end and the opposing rollers at the inlet end need to be connected to an external driving structure for use.

[0013] As a preferred technical solution of the utility model, there is an auxiliary connecting concave groove at the side end of the baffle, and there is a movable connection relationship between the baffle and the upper inner wall of the equipment body.

[0014] As a preferred technical solution of the utility model, the main direction of transmission from the No. 1 roller to the output end opposing roller is from left to right.

[0015] As a preferred technical solution of the present invention, the right outer end of the device body is specifically made of tempered glass.

[0016] As a preferred technical solution of the utility model, two groups of hydraulic lifting mechanisms are provided, which are within the same range of movement and distributed in horizontal straight lines.

[0017] Compared with the prior art, the utility model provides an impregnation device for carbon paper for batteries, which has the following beneficial effects:

[0018] 1. The impregnation device of carbon paper for battery is provided with roller structures with different arrangements and combinations from No. 1 to No. 12 and a hydraulic lifting mechanism. When the carbon paper is conveyed and driven by different roller structures, it starts to be impregnated with resin emulsion and other materials at the same time through the inside of the equipment body. In this process, the operator can control the hydraulic lifting mechanism through the numerical control panel, and adjust the height of the first driven combination roller and the second driven combination roller and the first active combination roller and the second active combination roller. When the hydraulic lifting mechanism is lowered to the bottom, the carbon paper is linearly driven from the first active combination roller to the output end driven roller, so the impregnation time is short. When the hydraulic lifting mechanism is raised to the highest point, the transmission distance of the carbon paper from the first active combination roller to the output end driven roller changes from a straight line to a broken line, which increases the impregnation time. At the same time, the impregnation effect can be accelerated by squeezing through the gap between the two roller structures. The above-mentioned setting can flexibly change the impregnation time of the carbon paper.

[0019] 2. The impregnation device for carbon paper for batteries is provided with facing rollers at the inlet end and the output end, as well as an ultrasonic vibration plate and a baffle. The carbon paper entering the solution is squeezed by two rollers with adjustable gaps, so that the solution quickly enters the material. At the same time, the air entrained in the material can be removed by squeezing, and the bubbles will quickly float to the surface of the solution. Because of the baffle, the bubbles are forced to stay on one side of the baffle and will not contact the surface of the material. The ultrasonic vibration plate at the bottom keeps the slurry uniform through high-frequency vibration. The measured material is designed to be vertically upward and does not need to contact other materials. Therefore, the surface of the measured material will not be contaminated.

[0028] The hydraulic lifting mechanism 5 also includes a hydraulic column 501 and a linkage block 502. The hydraulic column 501 is movably connected to the hydraulic lifting mechanism 5 through a sliding connection, and the linkage block 502 is fixedly connected to the top of the hydraulic column 501 through a fixed installation.

[0029] In this embodiment, the device body 1 also includes a height adjustment groove 101 and a sealed rear cover 102. The height adjustment groove 101 is provided with two groups and is provided on the inner end surface of the device body 1. The sealed rear cover 102 is fixedly installed and has a fixed connection relationship with the rear end of the device body 1. The introduction end facing roller 7 and the output end facing roller 17 are formed by a double-axis structure facing each other. The carbon paper moves from the internal gap. The first driven combination roller 9 and the second driven combination roller 10 and the first active combination roller 13 and the second active combination roller 14 are combination rollers, and the height is kept uniform through the linkage block 502 respectively. The rear ends of the output end facing roller 17 and the introduction end facing roller 7 need to be connected with the external drive structure for use. By connecting the external drive structure, the carbon paper moves from the internal gap. The first driven combination roller 9 and the second driven combination roller 10 and the first active combination roller 13 and the second active combination roller 14 are combination rollers. The dynamic structure can make the roller body rotatable and driven; there is an auxiliary connected concave groove at the side end of the baffle 3, and there is a movable connection relationship between the baffle 3 and the inner wall of the upper end of the equipment body 1. The baffle 3 can be connected and fixed more easily by setting the concave groove; the general direction of transmission from the No. 1 roller 6 to the output end opposite roller 17 is from left to right; the right outer end of the equipment body 1 is specifically made of tempered glass. By setting the side end of tempered glass material at the right outer end of the equipment body 1, the inside of the equipment body 1 can be observed by naked eyes; two groups of hydraulic lifting mechanisms 5 are provided, and they are in the same range of movement and are distributed in a horizontal straight line. By providing two groups of hydraulic lifting mechanisms 5, the carbon paper impregnation time can be flexibly adjusted.

[0030] The working principle and use process of the utility model are as follows: when the carbon paper is conveyed and driven by different roller structures, it starts to be impregnated with materials such as resin emulsion while passing through the inside of the equipment body 1. In this process, the operator can control the hydraulic lifting mechanism 5 through the numerical control panel 2, and thereby adjust the height of the first driven combined roller 9 and the second driven combined roller 10 as well as the first active combined roller 13 and the second active combined roller 14. When the hydraulic lifting mechanism 5 is lowered to the bottom, the carbon paper is linearly driven from the first active combined roller 13 to the output end driven roller 15, so the impregnation time is short. When the hydraulic lifting mechanism 5 is raised to the highest point, the transmission distance of the carbon paper from the first active combined roller 13 to the output end driven roller 15 changes from a straight line to a broken line, which increases the impregnation time. At the same time, the impregnation effect can be accelerated by squeezing through the gap between the two roller structures. The carbon paper entering the solution uses two pairs of rollers with adjustable gaps to squeeze the solution quickly into the material. At the same time, the air entrained in the material can be removed due to the squeezing effect, and the bubbles will quickly float to the surface of the solution. Because of the baffle 3, the bubbles are forced to stay on one side of the baffle 3 and will not contact the surface of the material.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
