Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin adhesive rolling equipment, in particular to an epoxy resin adhesive automatic rolling equipment for carbon fiber tubes. Background Art

[0002] In the new energy vehicle industry, some drive devices have the demand to reduce unit energy consumption, so composite materials are used for some transmission components.

[0003] Due to the advantages of composite materials such as high strength, good corrosion resistance and fast molding speed, the demand for composite materials products in the new energy industry has been growing in recent years. As one of the most important molding methods for composite materials, winding and curing molding has become the darling of the composite material industry. The research and development of related winding, gluing and curing equipment is an important part of its production. The winding molding process is to wind the continuous fiber (or cloth tape, pre-impregnated yarn) soaked in resin glue onto the core mold according to a certain rule, and then apply a certain ratio of epoxy resin on the surface, and then cure and demold to obtain the product.

[0004] After the winding process of the carbon fiber tube is completed, a certain proportion of epoxy resin needs to be evenly coated on the surface. However, this process is currently performed manually. The existing manual gluing method relies on manual mixing of the resin glue and then manual brushing. The production efficiency of pure manual work is low. Considering comprehensive factors such as labor costs, production hours, safety, and environment, the average unit manufacturing cost is relatively high. Due to the manual mixing of the resin glue ratio and the subsequent surface brushing, the uniformity is difficult to control, which is also closely related to the operator's proficiency. Either it is too thin and needs to be compensated, or it is too thick and needs to be polished. The uniformity of the product surface quality is very unstable. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to solve the problems of low production efficiency, high manufacturing cost and unstable product quality of the existing manual gluing method, an automatic epoxy resin glue rolling device for carbon fiber tubes is provided.

[0006] The utility model solves the technical problem by adopting the following technical solution: an automatic epoxy resin glue rolling device for carbon fiber tubes, comprising a base and a clamping mechanism arranged on the base, the clamping mechanism is used to fix the carbon fiber tube and can drive it to rotate, a displacement mechanism is arranged on the base, a gluing mechanism and a feeding mechanism are arranged on the displacement mechanism, the displacement mechanism is used to drive the gluing mechanism and the feeding mechanism to move on the base, the feeding mechanism is used to mix a variety of materials and supply them to the gluing mechanism, and the gluing mechanism is used to coat the surface of the carbon fiber tube with resin glue;

[0007] The feeding mechanism includes a mixing and conveying mechanism and a plurality of plunger pumps. The displacement mechanism is correspondingly provided with a control mechanism for driving the plunger pump to rise and fall. The input ends of the plurality of plunger pumps are arranged in corresponding barrels, and the output ends of the plunger pumps are connected to the mixing and conveying mechanism. The mixing and conveying mechanism is used to mix the materials conveyed by the plurality of plunger pumps and convey them to the gluing mechanism. Compared with the prior art, the present solution drives the gluing mechanism and the feeding mechanism to move axially along the base through the displacement mechanism, so that the feeding mechanism mixes a plurality of materials and conveys them to the coating mechanism, and then the coating mechanism coats the mixed materials along the axial direction of the carbon fiber tube to the outer peripheral surface thereof, thereby realizing automatic mixing and blending, and fully automatic gluing, thereby improving production efficiency, reducing labor intensity and labor costs, and ensuring stable and reliable product quality.

[0008] In order to realize the mixed conveying mechanism, some embodiments are preferred, wherein the mixed conveying mechanism includes a static mixer and a screw conveyor arranged in the static mixer, and the screw conveyor is used to convey the mixed materials to the gluing mechanism. The static mixer is used to mix and blend the various materials, and the screw conveyor conveys the blended materials to the gluing mechanism.

[0009] Since the input end of the plunger pump can only extract the material in the barrel, but cannot completely extract the material in the barrel, a lot of material remains in the barrel, resulting in a waste of resources. Manual scraping is required, which increases the production process, reduces production efficiency, and increases production costs. Preferably, in some embodiments, the control mechanism includes a cylinder arranged on a displacement mechanism, the plunger pump is installed on the protruding end of the cylinder, the input end of the plunger pump is located above the barrel, and a scraper disk is fixedly installed on the input end of the plunger pump. The scraper disk matches the inner wall of the barrel and is arranged in the barrel. By arranging a scraper disk on the input end of the plunger pump, the scraper disk can automatically drop with the reduction of the material in the barrel, and scrape the material on the inner periphery of the barrel. The structure is simple, the feeding efficiency of the plunger pump is improved, and manual scraping is not required.

[0010] In order to realize the gluing mechanism, some embodiments are preferred, wherein the gluing mechanism includes an outer shell, a silo for storing mixed materials is provided in the outer shell, a gluing roller is rotatably mounted on one end of the outer shell, and a discharge port is provided on one end of the outer shell close to the gluing roller, and the discharge port is used to supply materials to the gluing roller. The outer shell outputs the materials in the silo to the gluing roller through the discharge port, and the gluing roller rotates with the carbon fiber tube and applies the materials to the carbon fiber tube.

[0011] In order to ensure uniform glue on the glue roller, in some preferred embodiments, a scraper is provided on the outer shell, and the scraper is used to provide uniform glue on the glue roller. By providing the scraper on the outer shell, an outlet for uniform glue is formed between the scraper and the glue roller, so that excess glue can be scraped off to ensure uniform coating on the glue roller.

[0012] In order to better achieve the scraping of glue by the scraper, some preferred embodiments are that the scraper has a connecting portion and a scraping portion connected in sequence, the connecting portion is arranged on the outer shell, and the end of the scraper close to the glue roller is an arc surface. The connecting portion on the scraper is connected to the outer shell, and the arc-shaped scraping portion ensures that the glue is continuously and evenly output.

[0013] In order to improve production efficiency, in some preferred embodiments, a heating device is installed on one of the feeding mechanism and the gluing mechanism, and the heating device is located above the carbon fiber tube and is used to heat and cure the coating material on the carbon fiber tube. By arranging the heating device on the feeding mechanism or the gluing mechanism, the heating device accelerates the curing of the glue and improves the production efficiency of the carbon fiber tube.

[0014] In some preferred embodiments, the displacement mechanism includes a transverse displacement mechanism and a longitudinal displacement mechanism arranged on the transverse displacement mechanism, the transverse displacement mechanism is used to drive the longitudinal displacement mechanism to displace axially along the carbon fiber tube, and the longitudinal displacement mechanism is used to drive the gluing mechanism and the feeding mechanism to approach or move away from the carbon fiber tube.

[0015] In some preferred embodiments, the lateral displacement mechanism includes a lateral displacement platform, which is slidably arranged on a base along the axial direction of the carbon fiber tube, a first motor is fixedly mounted on the lateral displacement platform, a first rack is mounted on the base along the axial direction of the carbon fiber tube, a first gear is mounted on the output end of the first motor, and the first gear and the first rack are meshed with each other.

[0016] In some preferred embodiments, the longitudinal displacement mechanism includes a longitudinal displacement platform, which is arranged on a transverse displacement platform for radial sliding along the carbon fiber tube, a second motor is fixed to the transverse displacement platform, a second rack is installed on the transverse displacement platform along the radial direction of the carbon fiber tube, a second gear is installed on the output end of the second motor, and the second gear is meshed with the second rack.

[0017] The beneficial effects of the utility model are as follows: when the utility model is used, the automatic rolling epoxy resin glue coating equipment for carbon fiber tubes drives the glue coating mechanism and the feeding mechanism to move axially along the base through the displacement mechanism, so that the feeding mechanism mixes multiple materials and conveys them to the coating mechanism, and then the coating mechanism coats the mixed materials along the axial direction of the carbon fiber tube to its outer peripheral surface, thereby realizing automatic mixing and blending, and fully automatic glue coating, which improves production efficiency, reduces labor intensity and labor costs, and ensures stable and reliable product quality. The equipment is integrally welded with profiles, which is not only convenient to obtain materials, but also light in overall weight and small in size, so the manufacturing cost is low, the structure is simple, and the tension control is convenient. The system is simple and has a low failure rate. The modular design makes disassembly easy. The equipment is small in size and weight and is suitable for mass production. Therefore, the production efficiency is high, avoiding the existing manual gluing method, which requires manual mixing of resin glue and manual brushing. The pure manual production efficiency is low. Considering comprehensive factors such as labor costs, production hours, safety, and environment, the average unit manufacturing cost is relatively high. Due to the manual proportion of resin glue, the uniformity of surface brushing is difficult to control, which is also closely related to the operator's proficiency. Either it is too thin and needs to be compensated, or it is too thick and needs to be polished. The uniformity of product surface quality is very unstable. BRIEF DESCRIPTION OF THE DRAWINGS
