Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic composite material processing, in particular to a modified thermoplastic composite material forming and slitting device. Background Art

[0002] Thermoplastic composites are a new type of high-performance composite material with thermoplastic resin as the matrix, which has many outstanding characteristics and application potential. Thermoplastic composites are mainly composed of two parts. One part is the thermoplastic resin matrix, such as polypropylene, polycarbonate, polyamide, etc.; the other part is the reinforcing material, which is usually various fibers, such as short glass fiber, carbon fiber, textile fiber, etc. Thermoplastic composites are valued for their low density, high strength, good impact resistance, fatigue resistance, recyclability and rapid processing and molding. The modified thermoplastic composite molding and slitting equipment mainly uses the injection molding process to add thermoplastic composite particles into the material pipe through a funnel, and use a screw to drive the thermoplastic composite particles to roll. After being heated and melted into liquid by a heating tube, it is injected into the mold for cooling and molding. The formed thermoplastic composite material is slit by the cutting blade on the slitting roller.

[0003] In the utility model patent with patent announcement number CN218538122U, the left mold 23 is driven to move to the right by starting the hydraulic rod 22, so that the left mold 23 and the right mold 19 are separated. When the left mold 23 moves to a certain position to the right, the trigger rod 27 contacts the corresponding ejector pin 25, so that the ejector pin 25 ejects the finished product in the mold cavity. After the finished product is ejected, it falls onto the conveyor belt 3 through the rectangular opening 24 and is transported to the right through the conveyor belt 3. The baffles 28 on both sides can effectively prevent the finished product from falling from the conveyor belt 3. The modified thermoplastic composite material finished product moves to the right, and the cylinder 10 drives the push block 11 to keep the finished product at the center of the conveyor belt 3, and then enters the two limit blocks. 12, it is slit by the cutting blade 14 on the slitting roller 13, and enters the collection box 30 after the slitting is completed. At this time, the modified thermoplastic composite material is formed and slit. Although the above operation method can complete the shaping and slitting work, it also has the following problems: the technical problem is to improve the processing efficiency, but it is still necessary to wait for complete cooling in the mold before blanking, and the actual working time is not reduced. At the same time, since the mold is set vertically, the molded body of the thermoplastic composite material is ejected and falls on the conveyor belt below. This material discharge method will damage the shape of the material, and the arrangement of the material after falling cannot be completely in a horizontal forward transmission state, which will reduce the uniformity of subsequent cutting.

[0004] Therefore, it is necessary to provide a modified thermoplastic composite material molding and slitting equipment to solve the above technical problems. Utility Model Content

The hot melt box 2 is manually fed with materials to melt the thermoplastic composite particles into a liquid state and discharge them quantitatively through the discharge head 21. Directly below the discharge head 21 is a forming box 4, and the lower sides of the two sides of the forming box 4 are connected to the first support rod 5. The left side of the forming box 4 is connected to the electric telescopic rod 3. The right side of the forming box 4 is a cooling box 6, and the left and right sides of the cooling box 6 are provided with channels, the height of the channels is greater than the height of the forming box 4, and the cooling box 6 is provided with channels. A rectangular opening 101 is provided on the workbench 1 below the cooling box 6, and a collecting box 7 is installed inside the rectangular opening 101.

The molding box 4 is pushed toward the cooling box 6 by the electric telescopic rod 3, so that the molding box 4 is moved from the first support rod 5 to the moving mechanism 8, and is cut into strips after cooling.

[0024] Preferably, in one embodiment, Figure 1-3 As shown, the top surfaces of both sides of the forming box 4 are installed with clamping plates 41, and the clamping plates 41 are semicircular in structure as a whole. A handle 42 is installed on the top of the clamping plates 41, and the side of the forming box 4 facing the electric telescopic rod 3 is provided with a positioning groove 43, and the positioning groove 43 is plug-inly connected to the push block 31 of the electric telescopic rod 3. The first support rod 5 is screwed to the top surface of the processing table 1 through the mounting rod 51. Two groups of the first support rods 5 are installed at intervals, and the first support rods 5 are horizontally placed cylindrical structures as a whole. When one group of placement boxes 4 enters the cooling box 6 for cooling, the staff puts another group of placement boxes 4 into the first support rods 5 for support, and simultaneously injects liquid material into the placement boxes 4, and uses the cooling time of the previous group of placement boxes 4 to carry out the liquid injection and pre-cooling work of the next group of placement boxes 4, which significantly improves the processing efficiency.

[0025] Preferably, in one embodiment, Figure 3As shown, the inner height of the placement box 4 is higher than the height of the injected liquid. The purpose is to ensure that after the liquid composite material is injected, there is still a distance from the box opening of the placement box 4 to prevent leakage during movement.
