Description

Technical Field

[0001] This utility model relates to the field of tableware processing technology, and more specifically, to a compaction device for the production of melamine tableware. Background Technology

[0002] Melamine is a common material that is lightweight, hard, acid- and alkali-resistant, and is often used to make tableware. If the raw materials used to make melamine tableware are of poor quality, or if the pressure or temperature conditions during the manufacturing process are not ideal, the quality of the melamine tableware will be affected. During the production of melamine tableware, a compaction device is needed to apply uniform pressure to compact the raw materials into shape, thereby improving the density and strength of the product.

[0003] Among them, the pressing and molding device for melamine tableware processing disclosed in application number CN202210812826.2 is also an increasingly mature technology. After the concave mold seat and the convex mold seat are closed again and heated and shaped for a period of time, the air pump blows air in the opposite direction and blows air into the material collection tank through the telescopic hose to cool the concave mold seat, thereby cooling the shaped tableware, accelerating the cooling speed of the pressed tableware, reducing waiting time, and improving production efficiency.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist: Because the die holders of this type of molding device are all the same size, different equipment needs to be replaced when producing tableware of different shapes and sizes, which affects the overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a compaction device for the production of melamine tableware, so as to solve the problem of changing different equipment when producing tableware of different shapes and sizes as mentioned in the background art.

[0006] This utility model provides a compaction device for melamine tableware production, including a pressure application device and a replacement device; The pressure application device includes an electric telescopic rod, the telescopic end of which passes through the middle of the workbench and is connected to a movable plate via a convex ring. Support rods are provided at the four corners of the workbench and the top of each support rod is fitted with a fixed plate. The top of the movable plate is fixed to the four corners of a square plate using first hexagonal screws. A base plate is slidably mounted on the top of the square plate, and multiple lower molds are evenly distributed at the top of the base plate. A rectangular plate is mounted on the bottom of the fixed plate, and the four corners of the bottom of the rectangular plate are fixed using second hexagonal screws. A top plate is slidably mounted on the bottom of the rectangular plate, and multiple upper molds are evenly distributed at the bottom of the top plate.

[0007] In this embodiment, by placing the melamine raw material at the top of the lower mold, the electric telescopic rod is activated. The telescopic end of the electric telescopic rod has a self-locking property after moving to the appropriate length. The telescopic end of the electric telescopic rod drives the moving plate to move on the surface of the support rod through the convex ring, so that the moving plate moves smoothly up and down. The rising of the moving plate drives the square plate, the bottom plate, and the lower mold to move synchronously into the upper mold. The melamine raw material at the top of the lower mold is subjected to uniform pressure from the upper mold. This pressure is maintained for a set time to ensure that the raw material is fully compacted. Once the compaction time is reached, the electric telescopic rod retracts and drives the moving plate, the square plate, the bottom plate, the lower mold, and the raw material to move synchronously again, releasing the pressure on the raw material.

[0008] In one embodiment of this utility model, the replacement device includes multiple convex grooves on the opposite ends of a movable plate and a rectangular plate. Multiple convex strips are provided at the bottom end and the top end of the top end of the base plate. The convex strips slide along the inside of the convex grooves. L-shaped blocks are provided at both ends of the opposite ends of the movable plate and the rectangular plate. The L-shaped blocks are located at the top end of the movable plate and the bottom end of the rectangular plate. Screws are provided at the positions of the L-shaped blocks on the movable plate and the rectangular plate. The L-shaped blocks are threadedly connected to the screws with nuts.

[0009] In this solution, the L-shaped block is loosened by rotating the nut to position the moving plate and the rectangular plate, and the convex strips of the bottom plate and the top plate are slid out from the convex grooves of the moving plate and the rectangular plate. Then, the mold of the required size can be installed.

[0010] In one embodiment of this utility model, guide rods are symmetrically arranged at the top of each square plate, and pressure sensors are arranged at the top of each guide rod. Guide cylinders are symmetrically arranged at the bottom of each rectangular plate. The opening diameter of each guide cylinder is smaller than that of its inner wall. A pressure spring is arranged inside the guide cylinder, and a pressing ring is arranged at the bottom of each pressure spring. The guide rods are movably inserted into the interior of the guide cylinder.

[0011] In this solution, when the square plate rises, it drives the guide rod and pressure sensor into the interior of the guide cylinder. The pressing ring inside the guide cylinder is compressed by the pressure spring. The pressure sensor monitors the applied pressure in real time to avoid the problem of poor tableware quality caused by the misfitting of the upper and lower molds.

[0012] In one embodiment of this utility model, the electric telescopic rod is provided with a protective cover at the bottom of the workbench. The inside of the protective cover is fitted with a sleeve outside the electric telescopic rod. Heat dissipation grooves are provided around the protective cover. Connecting blocks are fixedly connected to both ends of the protective cover. The connecting blocks are fixedly installed at the bottom of the workbench by screw threads.

[0013] In this design, a protective cover supports and protects the electric telescopic rod, a sleeve positions the electric telescopic rod, and a heat dissipation groove is used to increase air circulation inside the protective cover.

[0014] In one embodiment of this utility model, the workbench is provided with legs at all four corners of its bottom and with reinforcing ribs in the middle, and each leg is provided with a caster wheel with a wheel brake at its bottom.

[0015] In this design, the support legs provide height and stability to the workbench, the reinforcing ribs increase the structural strength of the support legs, the casters allow for flexible movement of the equipment, and the wheel brakes lock the equipment to ensure its safety.

[0016] In one embodiment of this utility model, a switch panel is provided on the side of the workbench, and an electric telescopic rod switch and a pressure sensor switch are respectively provided on the top of the switch panel. The switch panel is electrically connected to an external power supply.

[0017] In this solution, power is supplied to the electrical equipment through a switch panel, and independent switches provide independent protection for the electrical equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are: (1) When it is necessary to change tableware of different shapes and sizes, rotate the nut to loosen the L-shaped block's positioning of the moving plate and rectangular plate, slide the convex strips of the bottom plate and top plate out from the convex grooves of the moving plate and rectangular plate, and then install the mold of the required size. (2) The telescopic end of the electric telescopic rod has a self-locking property after moving to a suitable length. The telescopic end of the electric telescopic rod drives the moving plate to move on the surface of the support rod through the convex ring, so that the moving plate can move up and down smoothly. The moving plate is fixed to the square plate by the first internal hex screw and the bottom plate is slidably installed. The lower mold at the top of the bottom plate moves synchronously to the upper mold through the rise of the moving plate. At the same time, the guide rod at the top of the square plate and the pressure sensor enter the interior of the guide cylinder. The pressing ring inside the guide cylinder is subjected to pressure to squeeze the pressure spring. The pressure sensor monitors the applied pressure in real time to avoid the problem of poor tableware quality caused by the mismatch between the upper and lower molds. The melamine raw material at the top of the lower mold is subjected to uniform pressure from the upper mold. This pressure is maintained for a set time to ensure that the raw material is fully compacted to achieve the required density and strength. Once the compaction time is reached, the electric telescopic rod retracts and drives the moving plate, square plate, bottom plate, lower mold and raw material to move down synchronously to release the pressure on the raw material.
