Description

Technical Field

[0001] The invention relates to the technical field of polystyrene processing, in particular to equipment and a method for producing a foamed polystyrene board. Background Art

[0002] Polystyrene resin is used as raw material, also known as extruded polystyrene board, which is a rigid foam insulation board formed by continuous extrusion and foaming through a special process. Polystyrene foam plastics are divided into molded polystyrene boards (EPS) and extruded polystyrene boards (XPS). Compared with EPS boards, XPS boards are the third generation of rigid foam insulation materials. From a technical point of view, it overcomes the complicated production process of EPS boards and has superior performance that EPS boards cannot replace. XPS boards are commonly used in the construction industry. Insulating and moisture-proof materials, they have been widely used in wall insulation, insulation of flat concrete roofs and steel structure roofs, low-temperature storage, moisture-proof insulation and control of ground expansion in the fields of ground, parking platforms, airport runways, highways, etc.

[0003] Publication (Announcement) No.: CN114850974A, discloses a cutting and grinding process for polystyrene insulation materials used for exterior walls, which solves the problem that the edges and corners of the insulation board are cut manually and automatically, resulting in angle errors, and repeated cutting is required to achieve the required cutting angle, which makes the cutting process more cumbersome. In addition, after cutting, the incision may be rough, resulting in gaps when the edges and corners come into contact with protrusions;

[0004] A certain amount of foaming agent is added during the production process of existing polystyrene boards. Under the action of the foaming agent, foaming will occur inside to form bubbles, thereby having a certain sound insulation effect. However, while generating bubbles, the edges of the polystyrene boards will become uneven, and after cutting, the incisions may be rough, resulting in gap problems during installation. In addition, the existing technology uses one-way grinding, which has a poor effect. Summary of the invention

[0019] Beneficial Effects

[0020] The present invention provides a device for producing a foamed polystyrene board and a method for using the same. Compared with the prior art, the device has the following beneficial effects:

[0021] (1) The equipment and method for producing expanded polystyrene boards, in which the raised portion of the special-shaped wheel and the adjusting block provided on one side of the third gear contact and slide with each other during the continuous rotation of the special-shaped wheel, thereby lifting the third gear upward and moving the second gear downward, so that the third gear and the first rack are meshed and transmitted with each other, and the second gear is no longer meshed and transmitted with the first rack, and the second meshing teeth of the second special-shaped gear begin to mesh with the third gear, driving the third gear to rotate, and the third gear drives the first rack, the first L-shaped sliding block and the sliding block to move to one side, so that the sliding block slides into the first sliding groove and the clamping plate clamps the polystyrene board, and the first meshing teeth of the first special-shaped gear begin to mesh and transmit with the second rack, thereby driving the second L-shaped sliding block and the mounting table to move, and the polystyrene board and the edge grinding assembly do not move synchronously, so that the grinding wheel grinds the polystyrene board flat.

[0022] (2) The equipment and production method for producing expanded polystyrene boards, wherein the second meshing teeth on the second rotating disk mesh with the first gear and drive it to rotate. At this time, the first meshing teeth of the first special-shaped gear do not mesh with the second rack, so that the edge grinding assembly does not move. The first gear drives the second gear on the other side to rotate. At this time, the second gear and the first rack mesh with each other. When the second gear rotates, it drives the first rack to move, thereby driving the first L-shaped sliding block and the sliding block located in the first sliding groove to slide, thereby driving the two sides of the polystyrene board to move to the other side on the edge grinding assembly for secondary grinding. As the first L-shaped sliding block and the sliding block move, the sliding block moves. , the sliding block slides out of the first sliding groove, the polystyrene plate is taken out and replaced with a new polystyrene plate for grinding. After the second edge grinding is completed, the clamping assembly and the edge grinding assembly can return to their original positions.

[0042] S2: When the rotating shaft 5 rotates, the two first special-shaped gears 501, the second special-shaped gear 701 and the special-shaped wheel 805 can be driven to rotate simultaneously. During the continuous rotation of the special-shaped wheel 805, the protrusion of the special-shaped wheel 805 and the adjustment block 803 provided on one side of the third gear 704 contact and slide with each other, thereby lifting the third gear 704 upwards and moving the second gear 703 downwards, so that the third gear 704 and the first rack 404 are meshed and transmitted with each other, and the second gear 703 is no longer meshed and transmitted with the first rack 404, and the second meshing tooth 7014 of the second special-shaped gear 701 starts to mesh with the third gear 704.

6. A method for producing a foamed polystyrene board, characterized in that: The method is carried out using the device as claimed in claim 5, which specifically comprises the following steps: S1: When the first L-shaped sliding block (401) slides out of the first sliding groove (2), the polystyrene plate is placed on the clamping assembly (4), and the two edges of the polystyrene plate are exposed outside the clamping assembly (4), and then the driving mechanism (6) is started to drive the rotating shaft (5) to rotate; S2: When the rotating shaft (5) rotates, the two first special-shaped gears (501), the second special-shaped gear (701) and the special-shaped wheel (805) can be driven to rotate simultaneously. During the continuous rotation of the special-shaped wheel (805), the protrusion of the special-shaped wheel (805) and the adjustment block (803) provided on one side of the third gear (704) contact and slide with each other, thereby lifting the third gear (704) upward and moving the second gear (703) downward, so that the third gear (704) and the first rack (404) are meshed and transmitted with each other, and the second gear (703) is no longer meshed and transmitted with the first rack (404), and the second meshing tooth (7014) of the second special-shaped gear (701) begins to mesh with the third gear (704). The three gears (704) are meshed, driving the third gear (704) to rotate, and the third gear (704) drives the first rack (404), the first L-shaped sliding block (401) and the sliding block (402) to move to one side, so that the sliding block (402) slides into the first sliding groove (2) and the clamping plate (403) clamps the polystyrene board, and the first meshing tooth (5014) of the first special-shaped gear (501) and the second rack (904) start to mesh and transmit, thereby driving the second L-shaped sliding block (901) and the mounting platform (902) to move, and making the polystyrene board and the edge grinding assembly (9) not move synchronously, so that the grinding wheel (903) grinds the polystyrene board flat; S3: As the rotating shaft (5) rotates, the second meshing teeth (7014) on the second rotating disk (7011) mesh with the first gear (702) and drive it to rotate. At this time, the first meshing teeth (5014) of the first special-shaped gear (501) do not mesh with the second rack (904), so that the edge grinding assembly (9) does not move. The first gear (702) drives the second gear (703) on the other side to rotate. At this time, the second gear (703) and the first rack (404) mesh with each other. When (703) rotates, it drives the first rack (404) to move, thereby driving the first L-shaped sliding block (401) and the sliding block (402) located in the first sliding groove (2) to slide, thereby driving the two sides of the polystyrene plate to move to the other side on the edge grinding assembly (9) for secondary grinding. As the first L-shaped sliding block (401) and the sliding block (402) move, the sliding block (402) slides out of the first sliding groove (2), and the polystyrene plate is taken out and replaced with a new polystyrene plate for grinding.
