Description

Technical Field

[0001] This utility model relates to the technical field of material extrusion mechanisms, specifically an epoxy resin extrusion mechanism. Background Technology

[0002] Epoxy resins are widely used in composite material manufacturing, electronic packaging, and building waterproofing due to their excellent adhesion, chemical resistance, and mechanical strength. Traditional epoxy resin coating processes typically involve applying bagged or drummed epoxy resin adhesive to the substrate surface manually or through simple mechanical extrusion.

[0003] When adding existing bagged epoxy resin, the packaging bag is opened and the material is poured out manually. Because epoxy resin is sticky, it is difficult to squeeze out the material from the packaging bag all at once. This not only increases the amount of manual labor, but also results in the material not being completely squeezed out, causing waste and increasing costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an epoxy resin extrusion mechanism that solves the problem of bagged epoxy resin during discharge. The extrusion mechanism enables better extrusion effect and higher extrusion efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an epoxy resin extrusion mechanism, comprising a coating conveyor belt and support plates disposed on both sides of the coating conveyor belt, wherein an extrusion mechanism is disposed on the support plates, the extrusion mechanism comprising a drive roller and a driven roller, a low-speed drive motor is fixed to the outside of the support plates, the drive roller and the driven roller are close together to clamp the bagged epoxy resin material, and the low-speed drive motor drives the drive roller to rotate, thereby driving the driven roller to rotate and extruding the bagged epoxy resin material.

[0006] Furthermore: a groove is provided on the support plate, the groove is horizontally arranged with the drive roller, a slider is slidably connected in the groove, the driven roller is rotatably arranged between the two sliders, a first cylinder is fixed at the outer end of the support plate, the output end of the first cylinder passes through the groove and is fixedly connected to the slider, so that the driven roller can move closer to or away from the drive roller to clamp and squeeze the bagged epoxy resin.

[0007] Furthermore: the low-speed drive includes a motor and a reducer, the output end of which is connected to the drive roller, driving the drive roller to rotate at a low speed, thereby causing the driven roller to rotate synchronously to squeeze the epoxy resin inside the packaging bag.

[0008] Furthermore: a second cylinder is fixed to the upper end of the support plate. The second cylinder is located between the driving roller and the driven roller, and a receiving hopper is fixed to the output end for adjusting the height of the receiving hopper to receive the epoxy resin extruded from the driving roller and the driven roller.

[0009] Furthermore: a fixing rod is provided between the support plates, and a connecting seat is rotatably connected to both ends of the fixing rod. The connecting seat is fixedly connected to the inner side wall of the support plate. A scraper is fixed on the fixing rod and is tangent to the drive roller, used to scrape off the epoxy resin remaining on the surface of the drive roller.

[0010] Furthermore, the connecting seat is fixed by screws to adjust the angle of the fixing rod, ensuring that the scraper always remains in contact with the drive roller.

[0011] This invention provides an epoxy resin extrusion mechanism. Compared with the prior art, it has the following advantages:

[0012] This epoxy resin extrusion mechanism achieves efficient extrusion and reduces waste by using a combination of active and driven rollers to extrude bagged epoxy resin; a low-speed drive ensures stable conveying; a first cylinder precisely controls the clamping force; the receiving hopper has an adjustable height to optimize coating effect; a scraper cleans residual resin from the active roller to maintain uniform coating; the overall structure is compact, easy to operate, and improves production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: an epoxy resin extrusion mechanism; specifically, it consists of a coating conveyor belt 2, which applies epoxy resin adhesive to the surface. Epoxy resin coating is achieved by mixing liquid epoxy resin (main agent) with a curing agent, coating it onto the substrate surface, and then curing it (at room temperature or with heating) to form a cross-linked network structure, ultimately forming a robust coating. This is existing technology and will not be described in detail here. By setting an extrusion mechanism at the upper end of the coating conveyor belt 2, the epoxy resin adhesive in the bag is completely extruded, avoiding… To avoid waste, support plates 1 are fixed on both sides of the coating conveyor belt 2. The extrusion mechanism is located at the upper end of the support plates 1. The extrusion mechanism includes a drive roller 3 and a driven roller 8. The bagged epoxy resin adhesive is placed from top to bottom between the drive roller 3 and the driven roller 8. Then, the driven roller 8 pushes the drive roller 3 to clamp the upper end of the bagged epoxy resin adhesive. The rotation of the drive roller 3 drives the driven roller 8 to rotate. At the same time, the bagged epoxy resin adhesive pulls the packaging bag upward. The two work together to squeeze out the epoxy resin adhesive in the bag, thereby achieving the effect of fast and effective material feeding.

[0020] The extrusion mechanism also includes a low-speed drive motor 4, which is composed of a motor and a reducer. The output end of the low-speed drive motor 4 is fixedly connected to the drive roller 3. The low-speed drive motor 4 drives the drive roller 3 to rotate at a low speed. A through groove 5 is provided on the support plate 1. The height of the groove 5 is matched with the height of the drive roller 3. A first cylinder 7 is fixed on the outer end face of the support plate 1. The output end of the first cylinder 7 passes through the support plate 1 into the groove 5. A slider 6 slides in the groove 5. The driven roller 8 is located between the two sliders 6 and rotates. The first cylinders 7 on both sides control the driven roller 8 to push it to the drive roller 3 to clamp the packaging bag. Since the packaging bag contains epoxy resin, which has a certain viscosity, the driven roller 8 can be driven to rotate by the drive roller 3. The drive roller 3 then drives the driven roller 8 to squeeze the packaging bag, squeezing out the epoxy resin inside the packaging bag, thereby maximizing the utilization of the epoxy resin inside the packaging bag.

[0021] A second cylinder 9 is fixed at the upper end of the support plate 1. The output end of the second cylinder 9 is located between the driving roller 3 and the driven roller 8. A receiving hopper 10 is fixed at the output end of the second cylinder 9. The receiving hopper 10 evenly drips epoxy resin onto the coating conveyor belt 2. The coating mechanism at the lower end of the receiving hopper 10 scrapes the epoxy resin on the coating conveyor belt 2 for use. The coating mechanism is a known technology and will not be described in detail here. The second cylinder 9 can drive the receiving hopper 10 to move up and down for adjustment, which facilitates the receiving of epoxy resin.

[0022] A fixing rod 11 is provided between the support plates 1. A connecting seat 12 is rotatably provided at both ends of the fixing rod 11. The connecting seat 12 is fixed to the inner side wall of the support plate 1. The rotation direction of the fixing rod 11 is fixed on the connecting seat 12 by screws. A scraper 13 is fixedly connected to the fixing rod 11. The scraper 13 is tangential to the drive roller 3. In this way, the residual epoxy resin on the drive roller 3 can be scraped off by the scraper 13 and put into the receiving hopper 10 to avoid material waste.
