Description

Technical Field

[0001] This invention relates to the field of square conveyor belt processing, specifically to a rapid prototyping device and method for square conveyor belts. Background Technology

[0002] Conveyor belts, as the name suggests, are belt-shaped devices used to transport objects. They can move objects from one place to another, and their applications in daily life are numerous. Examples include escalators in shopping malls, moving walkways in airports, automated loading and unloading conveyor belts at docks, factory production lines, and agricultural machinery such as combine harvesters and rice transplanters. Most conveyor belts are used for material transportation and belong to the rubber conveyor belt series. Their main function is to support and transport materials. Square conveyor belts are one type of conveyor belt.

[0003] Square conveyor belts are typically composed of one or more layers of materials. Depending on the material and the transportation environment, different thicknesses and patterns of square conveyor belts are selected. The tension of the conveyor belt in the pushing direction is usually provided by industrial polyester fabric, which has lateral stability. The coating is composed of materials such as PVC, PU, ​​PE, and SIR, which ensures the stability and mechanical properties of the square conveyor belt, making it suitable for more application scenarios.

[0004] The manufacturing process of a square conveyor belt requires the use of a square conveyor belt mold, i.e., molding equipment. People put the rubber material used to make the square conveyor belt into the mold, and after curing, it is molded. The molded square conveyor belt is then removed from the mold, thus completing the manufacturing of the square conveyor belt.

[0005] However, the molding equipment has the following defects during use: Referring to the currently published document "CN201921384543.2", although the problem of material adhesion after the square conveyor belt is prepared by "the first ejector plate drives the second ejector plate on the connecting rod to rise, so that the second ejector plate ejects the injection molded product, and at the same time as the second ejector plate ejects, the pressure spring applies pressure upward, so that the product stuck in the mold is ejected, avoiding the phenomenon of product sticking", the traditional molding equipment is exposed to the external environment at the beginning of the preparation of the square conveyor belt. Dust floating in the external environment adheres to the molding equipment, which leads to impurities adhering to the inner side of the square conveyor belt after curing, resulting in a low pass rate of tensile force test of the finished product. Summary of the Invention

[0006] The purpose of this invention is to provide a rapid prototyping device and method for square conveyor belts, in order to solve the problem mentioned in the background art that in the initial stage of the preparation of square conveyor belts, the forming equipment is exposed to the external environment, and dust floating in the external environment adheres to the forming equipment. This results in impurities adhering to the inner side of the solidified square conveyor belt, leading to a low pass rate in tensile strength testing of the finished product.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a square conveyor belt rapid prototyping device, comprising a fixed base, four uprights fixedly installed on one side of the top of the fixed base, and an injection mechanism fixedly installed on the other side of the top of the fixed base. The tops of the four uprights are respectively fixedly connected to the four corners of the bottom of the top plate. Lifting rings are slidably connected to the middle of each of the four uprights. The opposite sides of the four lifting rings are respectively fixedly connected to the two ends of both sides of a connecting platform. A molding upper mold is fixedly installed at the bottom of the connecting platform. A perforated insulation board is fixedly installed at the bottom of the molding upper mold. Fixed rings located below the lifting rings are fixedly installed on each of the four uprights. The opposite sides of the four fixed rings are respectively fixedly connected to the two ends of both sides of a molding lower mold. When the perforated insulation board is energized, the heating wire inside the perforated insulation board heats up, heating and curing the adhesive from the top.

[0008] As a preferred embodiment of the present invention, the injection mechanism includes a raw material tank, an extraction pipe, a pump body, a purification pipe, and an injection hose. The pump body's inlet is fixedly connected to the extraction pipe, and the end of the extraction pipe away from the pump body is fixedly connected to the raw material tank. The pump body's outlet is fixedly connected to the purification pipe and the injection hose. When the pump body is powered on and started, it extracts raw material from the raw material tank through the extraction pipe. The extracted raw material is then injected into the lower molding die through the purification pipe to clean the lower molding die with adhesive. The pump body extracts raw material from the raw material tank through the extraction pipe, and the extracted raw material is then injected into the molding equipment through the injection hose.

[0009] As a preferred embodiment of the present invention, the bottom end of the raw material tank and the bottom end of the pump body are both fixedly connected to the fixed base. The end of the injection hose away from the pump body is fixedly connected to the side adjacent to the upper molding die. The end of the impurity removal pipe away from the pump body is fixedly connected to the side adjacent to the lower molding die.

The demolding mechanism includes two movable blocks, a demolding template, and a demolding cylinder. Movable grooves are provided on both sides of the inner wall of the lower molding die. Movable blocks are slidably connected inside the two movable grooves. A demolding template is fixedly installed between the two movable blocks. The middle of the bottom end of the demolding template is fixedly connected to the movable end of the demolding cylinder. The middle of the demolding cylinder is fixedly connected to the support frame. When the solenoid valve on the demolding cylinder is opened, compressed air is input into the demolding cylinder, pushing the piston to reciprocate within the demolding cylinder. The demolding cylinder performs telescopic movement, pushing the demolding template from the bottom to move up and down. The demolding template slides along the movable grooves with the movable blocks and is pushed upward from the bottom of the formed square conveyor belt for demolding.

[0012] As a preferred embodiment of the present invention, a lifting cylinder is fixedly installed in the middle of the top plate. The movable end of the lifting cylinder is fixedly connected to the middle of the top of the connecting platform. When the solenoid valve on the lifting cylinder is opened, compressed air is input into the lifting cylinder, pushing the piston to reciprocate in the cylinder. The lifting cylinder performs telescopic movement, and the lifting cylinder pushes the connecting platform from the top. The connecting platform drives the lifting ring to slide along the upright, and the connecting platform drives the upper forming mold to move synchronously, so that the upper forming mold is inserted into the lower forming mold.

[0013] This invention discloses a method for using a rapid prototyping device for square conveyor belts, comprising the following steps:

[0014] Step 1: Cleaning the lower mold: The pump is powered on and started. The pump draws raw material from the raw material tank through the extraction pipe. The extracted raw material is then injected into the lower mold through the impurity removal pipe to clean the lower mold with adhesive.

[0015] Step 2: Adjust the height of the upper forming mold: The lifting cylinder is pushed downward from the top of the connecting platform, so that the upper forming mold is engaged in the lower forming mold;

[0016] Step 3: Adjust the temperature of the molding equipment: After the perforated insulation board and heating plate are powered on, they generate heat to heat and keep the molding equipment warm. The temperature sensor monitors the temperature in real time.

[0017] Step 4: Material injection by the injection mechanism: The pump body draws raw materials from the raw material tank through the extraction pipe, and injects the extracted raw materials into the molding equipment through the injection hose;

[0018] Step 5, Heating and Curing: The perforated insulation board and heating plate are used to heat and cure the raw materials;

[0019] Step 6, Demolding: The demolding cylinder pushes the demolding plate from the bottom, and the demolding plate pushes out the solidified square conveyor belt;

[0020] Step 7: Finished Product Placement: After forming, the square conveyor belt needs to be laid flat and neat, and should not be placed or squeezed randomly.

[0021] The raw materials for producing square conveyor belts, by weight percentage, are: hydrogenated nitrile rubber 100%, zinc oxide 6%-8%, stearic acid 1%-2%, metal soap base mixture 1.5%-2%, N-isopropyl-N'-phenyl-p-phenylenediamine 1.5%-2.5%, antioxidant RD 1%-2%, 2-thiol-benzoimidazole 1%-2%, microcrystalline wax 1.5%-2.5%, high abrasion-resistant carbon black 32%-38%, and silica 10%- 14%, acetylacetic acid tributyl ester 10%-14%, sulfur 0.4%-0.6% (80% content), bis(pentamethylene)thiuram tetrasulfide 1.5%-2% (80% content), 4-4'-dimorpholine disulfide 1.8%-2.2% (80% content), tetraethylthiuram disulfide 1.3%-1.5% (80% content), and N-cyclohexyl-2-benzothiazole sulfenamide 1.7%-2% (80% content).

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. By setting up an injection mechanism, before the square conveyor belt is formed, the pump body extracts the rubber material from the raw material tank through the extraction pipe. The extracted rubber material is then transported to the lower mold through the impurity removal pipe to clean the impurities adhering to the lower mold, so as to avoid impurities in the mold from mixing into the rubber material and reducing the pass rate of the stretched square conveyor belt.

[0024] 2. By setting up a demolding mechanism, the demolding cylinder pushes the demolding plate from the bottom. The demolding plate moves up and down in the lower mold through the movable block. The demolding plate pushes the formed square conveyor belt from the bottom to demold it, thus shortening the forming time of the square conveyor belt.

[0025] 3. By setting a perforated insulation board and a heating plate, the perforated insulation board insulates the rubber material from the top, and the heating plate heats up the internal heating wires after being powered on, which heats and cures the rubber material in the lower mold.
