[0001] The utility model patent relates to the technical field of composite material preparation equipment, specifically, to an eccentrically adjustable resin automatic replenishing device. Background Art

[0002] In the two-step preparation process of composite materials (prepreg), the first step is to use a coating machine to prepare a finished film (the surface of the substrate carries a uniform resin); during the use of the coating machine, it is necessary to continuously add and replenish resin raw materials.

[0003] The resin of the coating machine is solid at room temperature, and the coating machine has strict requirements on the temperature of the added resin (too large a temperature difference will affect the quality of the film); there are two methods for adding resin to the existing equipment: one is to heat the resin to the specified temperature in an external oven and then transfer it to the coating machine manually; the other is to have a grid-type heating plate above the coating machine, and the solid resin is placed on the grid heating plate. When the resin melts, it falls down along the grid gap into the coating machine. The above two methods have low working efficiency, and it is difficult to drip high-viscosity resins, and the resin replenishment speed cannot be effectively controlled. In the actual use of the coating machine, the viscosity of the resin used by different customers varies greatly, ranging from 1000cps to 500000cps, which are all within the actual use range of the coating machine. In order to meet the needs of different customers for the resin replenishment device, different viscosities are added. A resin replenishment device with an adjustable resin replenishment device applicable to the resin addition range is now needed; therefore, an eccentric adjustable resin automatic replenishment device is proposed to address the above problems.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The implementation of the utility model is described in detail below in combination with a specific embodiment, including a wall panel 1, a frame structure formed by two wall panels 1, a mounting hole is processed on the wall panel 1, an eccentric bearing sleeve 5 is installed in the mounting hole, a bearing body 6 is installed in the eccentric bearing sleeve 5, and a heating roller 2 is installed on the inner ring of the bearing body 6; when working, the heating roller 2 is driven to rotate by the bearing, and the resin is heated and melted by the heating roller 2.

[0021] A glue baffle assembly 3 is installed above the heating roller 2, and the glue baffle assembly 3 is fixedly installed on the inner side of the wall panel 1 to form a sol zone with the heating roller 2. A glue scraping assembly 4 is installed below the heating roller 2, and the glue scraping assembly 4 is fixedly installed on the inner side of the wall panel 1; when working, the melted resin can be scraped off the heating roller 2 through the glue scraping assembly 4.

[0022] A reduction motor 8 is fixedly installed on the outer side of the wall panel 1 on one side, and a transmission sprocket 9 is installed on the shaft end on the same side of the reduction motor 8 and the heating roller 2 respectively, and the two transmission sprockets 9 are connected by chain transmission.

[0023] A positioning pin hole 71 is provided on the wall panel 1 and at the edge of the mounting hole. The positioning pin hole 71 is arranged at a distance L from the center of the mounting hole.

[0024] The eccentric bearing sleeve 5 is provided with a second locating pin hole 72, which is adapted to the first locating pin hole 71. The second locating pin hole 72 is evenly distributed at a distance L from the center of the outer cylindrical surface, and is used to position the eccentric bearing sleeve 5; the flange end face of the eccentric bearing sleeve 5 is provided with a long slot hole to adjust the eccentricity value in a wide range. When in use, the marked clearance value of the processed locating pin hole can be used, or it can be arbitrarily adjusted to a non-calibrated value for use, so as to ensure that the adjustment amount on both sides is consistent.

[0025] The outer circumferential surface of the eccentric bearing sleeve 5 is not concentric with the inner bearing hole, and the eccentricity is Lp (the eccentricity is divided into positive and negative).

[0026] When working, the center distance of the mounting holes on the wall panel 1 - the roller diameter of the heating roller 2 = the reference gap value (t);

[0027] Glue amount adjustment method:

[0028] The eccentric bearing sleeves 5 at both ends of the heating roller 2 are rotated and adjusted to make the rotation directions of the eccentric bearing sleeves 5 at both ends of the heating roller 2 the same, and make the second positioning pin hole 72 and the first positioning pin hole 71 of the same adjustment amount at both ends coincide. At this time, the adjustment amount of the heating roller 2a is Lpa, and the adjustment amount of the heating roller 2b is Lpb. At this time, the gap value of the heating roller 2 is: T = t + Lpa + Lpb;

[0029] Glue supply scheme:

[0030] The heating roller 2 is heated, and resin is placed in the sol area surrounded by the heating roller 2 and the glue baffle assembly 3.

[0031] Start the reduction motor 8, and the heating roller 2 rotates downward from the center under the drive of the transmission sprocket 9 and the chain. At this time, the resin in the sol area moves to the gap of the heating roller 2 under the rotation of the heating roller 2, and part of the resin passes through the gap quantitatively under the limit of the gap. When the quantitative resin passing through the gap of the heating roller 2 continues to move downward under the drive of the heating roller 2, it is peeled off from the heating roller 2 by the scraping component 4 and falls to the use area below the dripping value; the method for adjusting the gap value of the heating roller 2 can be adjusted according to the viscosity of the resin. For high-viscosity resin, the gap value of the heating roller 2 can be increased to increase the resin passing amount per unit time, and prevent the resin from being retained in the gap of the heating roller 2 and unable to move downward.

[0032] When the glue supply speed of the resin replenishing device cannot meet the use requirements, the eccentricity value of the eccentric bearing sleeve 5 can be adjusted to select a larger gap value for glue supply.

[0033] The transmission sprocket 9 includes a mounting sleeve 91, a connecting sleeve 93 and a sprocket body 95. The mounting sleeve 91 is connected to the device shaft, and the sprocket body 95 is fixedly connected to the outer wall of the connecting sleeve 93. The connecting sleeve 93 is sleeved on the outer side of the mounting sleeve 91. The inner wall of the connecting sleeve 93 is symmetrically fixed with a limit block 94. A limit groove 92 is provided on the outer wall of the mounting sleeve 91, and the limit block 94 is inserted into the limit groove 92. A threaded hole 1 97 is provided on the side wall of the connecting sleeve 93, and a threaded hole 2 98 is provided at a corresponding position on the side wall of the mounting sleeve 91. A fixing screw is threadedly connected between the threaded hole 1 97 and the threaded hole 2 98. Bolt 96; when working, it is slidably installed in the limiting groove 92 through the limiting block 94, and then the connecting sleeve 93 is installed on the outside of the mounting sleeve 91, and is installed inside the threaded hole 1 97 and the threaded hole 2 98 through the fixing bolt 96, the connecting sleeve 93 and the mounting sleeve 91 are fixed together, and then the assembly of the transmission sprocket 9 is completed. The sprocket body 95 is provided with a pair of independent connecting sleeves 93 respectively connected together. The teeth on the sprocket body 95 may be damaged during long-term use. At this time, the fixing bolt 96 is removed, and then the damaged connecting sleeve 93 and the sprocket body 95 can be removed together, which is convenient for replacing the sprocket body 95, thereby reducing costs.
