Description

Technical Field

[0001] The utility model relates to a bubble eliminating device for epoxy resin processing, belonging to the field of epoxy resin processing. Background Art

[0002] Epoxy resin is a high molecular polymer, which refers to a class of polymers containing two or more epoxy groups in the molecule. It is the condensation product of epichlorohydrin and bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be opened with a variety of compounds containing active hydrogen, and cured and cross-linked to form a network structure. Therefore, it is a thermosetting resin. During the processing of epoxy resin, due to the flow of epoxy resin, it is easy to cause bubbles to remain inside the epoxy resin. The produced epoxy resin needs to be defoamed.

[0003] In the prior art, stirring is often used to eliminate bubbles in the epoxy resin during the debubbling process. The stirring blades break the air bubbles in the raw materials, thereby achieving a defoaming effect. However, due to the characteristics of the epoxy resin itself, the epoxy resin has a certain viscosity. After processing, the epoxy resin is easy to adhere to the stirring blades or other defoaming structure surfaces after debubbling processing, and secondary cleaning is required. After unloading, there is a large amount of residual raw material on the stirring blades or internal contact parts. It is necessary to design a bubble elimination device for epoxy resin processing that is convenient for reducing the residual raw material during the unloading process. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a bubble elimination device for epoxy resin processing to solve the problems raised in the above-mentioned background technology. The utility model automatically performs cleaning and unloading through negative pressure.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a bubble elimination device for epoxy resin processing, including a bracket, the top of the bracket is fixedly connected with a fixing seat, one side of the fixing seat is installed with a buffer connecting seat, the outer wall of the buffer connecting seat is snap-connected with a vibration cylinder, one side of the vibration cylinder is fixedly connected with a discharge chute, the top of the vibration cylinder is installed with a driving cylinder, and the output end of the driving cylinder is fixedly connected with a sealing door.

[0006] A driving motor is installed on one side of the bracket, and the output shaft of the driving motor is fixedly connected to a pulley through a coupling. An impact assembly is installed on the inner side of the bracket, and an exhaust assembly is installed on the outer wall of the fixing seat.

[0007] Furthermore, a feeding pipe opening is installed on the top of the vibration cylinder, a sealing plate is installed on the inner wall of the vibration cylinder, and the sealing door slides upward along the sealing plate.

[0008] Furthermore, the inner wall of the impact assembly includes an impact roller, a connecting shaft, a first gear and a linkage gear, one end of the pulley is fixedly connected to the connecting shaft, one end of the connecting shaft is fixedly connected to the impact roller, one end of the impact roller is fixedly connected to the first gear, and a side bearing of the bracket is connected to the linkage gear.

[0009] Furthermore, a steel ball is rollingly connected to the outer wall of the impact roller, the impact roller is arranged in two groups, and the vibration cylinder is located between the impact rollers.

[0010] Furthermore, the first gear and the linkage gear are meshed with each other, and the first gear is meshed with another first gear through the linkage gear for transmission.

[0011] Furthermore, a belt is arranged outside the pulley, and the pulley and another pulley are driven by the belt.

[0012] Furthermore, the interior of the vacuum pump assembly includes a vacuum pump, a connecting pipe, a vacuum end and a discharge plate. The vacuum pump is installed on the outer wall of the fixed seat. The output end of the vacuum pump is fixedly connected to the connecting pipe. One side of the vibration cylinder is provided with a vacuum end. The interior of the vibration cylinder is snap-connected with a discharge plate, and the other end of the connecting pipe is butt-jointed with the vacuum end, and the outer ring of the discharge plate is set as a rubber ring.

[0013] The beneficial effects of the utility model are as follows: after the bubbles are eliminated by the device, the bubble elimination device uses a vacuum pump to draw the inside of the vibrating cylinder into a vacuum state, creating a negative pressure environment, so that during vibration, the discharge plate is located on the inner side of the cylinder, and after the sealing door is opened, leakage occurs on the right side inside, causing the discharge plate to move under the influence of air pressure, so that the discharge plate discharges the epoxy resin after the internal defoaming process, thereby unloading. During the unloading process, the adhesion and residue of the epoxy resin on the inner wall are reduced, so that the wall hanging phenomenon of the cylinder is reduced, and there is no need for secondary cleaning.

[0014] The pulley is driven to rotate by a driving motor, and the impact component is driven by the belt to perform high-frequency impact on the vibration cylinder, thereby generating vibration, so as to vibrate and defoam the epoxy resin raw material inside, reduce the residual gaps between the epoxy resins, and increase the impact frequency by setting up two sets of impact rollers. At the same time, the buffer connection seat above is connected to maintain the balance during the impact process, making the defoaming effect more significant. Due to the internal vacuum environment, bubble regeneration is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The above structure drives the impact roller 1001 to rotate and impact through the first gear 1003.

[0027] Preferably, the outer wall of the impact roller 1001 is rollingly connected with a steel ball, the impact roller 1001 is arranged in two groups, and the vibration cylinder 4 is located between the impact rollers 1001 .

[0028] The above structure uses the steel ball to impact the cylinder wall of the vibration cylinder 4, so that the vibration cylinder 4 vibrates at a high frequency.

[0029] Furthermore, the first gear 1003 and the linkage gear 1004 are meshed with each other, and the first gear 1003 is meshed with another first gear 1003 through the linkage gear 1004 for transmission.

[0030] The first gear 1003 is driven by the linkage gear 1004, thereby driving the vibration cylinders 4 on both sides to collide.

[0031] Furthermore, a belt is provided outside the pulley 9, and the pulley 9 and another pulley 9 are driven by the belt.
