Description

Technical Field

[0001] The present invention belongs to the technical field of PVC board production and processing, and particularly relates to an extrusion molding and conveying device for PVC boards. Background Art

[0002] When the existing PVC boards are produced and processed, raw material particles are melted and extruded through an extruder, then passed through a molding machine for extrusion molding, and then conveyed to a cutting device for cutting and forming. At present, when the existing molding machine is performing extrusion molding, the cooling effect of the molding plate in the molding machine on the PVC board is low, the utilization rate of the coolant is low, which affects the forming of the board. Moreover, after the coolant is cooled, it cannot be recycled, resulting in an increase in the overall cost and also prone to waste of the coolant.

[0003] In order to solve the above technical problem, in the currently publicly available literature, CN205297127U - an extrusion molding and conveying system for PVC boards used in rail transit trains, is disclosed to be provided with an extruder, a molding machine, a conveyor and a tractor. The molding machine includes multiple groups of molding plates, and the distance between the molding plates gradually decreases along the conveying direction of the PVC board. Cooling grooves for storing coolant are provided in each molding plate, and a plurality of partition plates are provided in the cooling grooves. The partition plates form a diversion cavity in an S-shaped winding and rugged shape in the cooling groove, and it also includes a circulation tank for coolant circulation.

[0004] Although through the design of the cooling groove and the coolant, the molding plate can cool and lower the temperature of the PVC board to a certain extent during extrusion. However, for the existing PVC board extrusion molding and conveying device, when using the S-shaped winding and rugged diversion cavity to circulate water, during molding and cooling, since the temperature of the PVC board is relatively high, the cold water exchanges heat with the temperature of the PVC board continuously during the process of passing through the diversion cavity. This will cause the temperature of the cold water to gradually increase when passing through the diversion cavity, resulting in different water temperatures at various parts in the diversion cavity. Usually, only the part near the water inlet can maintain the cold water temperature, greatly reducing the cooling effect on the PVC board during extrusion molding. In addition, when the cooling water is recycled, it is only recovered by the way of rotary spraying, and it is difficult to cool down quickly, which will also affect the cooling effect on the PVC board during extrusion molding. In addition, the existing device is usually only suitable for the extrusion molding and conveying of a single type of PVC board, and its functionality is not strong. Therefore, we provide an extrusion molding and conveying device for PVC boards to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a PVC board extrusion molding and conveying device. Through the specific settings of the molding mechanism and the water circulation barrel, it solves the problems of the existing PVC board extrusion molding and conveying device. The existing device uses an S-shaped winding and rugged diversion cavity for circulating water, resulting in poor cooling effect on the PVC board during molding and cooling. In addition, when the cooling water is recycled, it is only recovered by the way of rotary spraying, which is difficult to quickly cool down and will also affect the cooling effect of the PVC board during extrusion molding. Moreover, the existing devices are often only suitable for the extrusion molding and conveying of a single type of PVC board, with poor functionality.

[0019] 2. Through the specific arrangement of the water circulation barrel, the recycled water will first be sprayed into the inner barrel through the shower head for preliminary heat dissipation, and then rotated and sprayed onto the inner wall of the outer barrel. During the spraying process, secondary heat dissipation is completed. The water after spraying will collide with the inner wall of the outer barrel, and during the rebounding process, tertiary heat dissipation is completed. At the same time, a rising air flow is formed by the rotating spray pipe, and the heat of the cooling water is carried away in a timely manner by the rising air flow to complete quaternary heat dissipation. Finally, through the action of the first stirring rod and the action of the rotating bent rods and the second stirring rods, the water at the inner bottom of the outer barrel can be stirred at a high speed for heat dissipation to complete quinary heat dissipation. The water circulation barrel adopts a layered and step-by-step heat dissipation method, which can quickly cool the water flowing back into the water circulation barrel to a cooled state.

[0020] 3. In the forming mechanism of the present invention, the upper forming plate and the lower forming plate can be horizontally moved as a whole. When it is necessary to use a set of forming mechanisms in superposition, by replacing the plates with different heights in a set of forming mechanisms, the plate with the required thickness can be formed by extrusion in multiple steps. When it is necessary to use a set of forming mechanisms separately, by replacing the plates with different textures on the contact surfaces in a set of forming mechanisms, different textures can be formed on the three parts of the plate body through the separate extrusion of each forming mechanism. Then, it is conveyed to the next processing step by a conveyor, and after cutting in the next processing step, plates with different textures are formed, and plates with different textures can be obtained at one time, improving functionality.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all of the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The operation process of this embodiment is as follows: When a set of forming mechanisms 200 need to be used in a superposed manner, first replace the plate surface 2002 of a set of forming mechanisms 200 with different heights. By changing the height of the plate surface 2002 of the forming mechanism 200, the distance between the upper forming plate 240 and the lower forming plate 250 on the forming mechanism 200 is adjusted, that is, the distance through which the raw material passes is changed. After adjustment, ensure that the distance through which the raw material passes in the middle of a set of forming mechanisms 200 gradually decreases in the conveying direction. At this time, when the raw material passes through a set of forming mechanisms 200, it is extruded in multiple times by each forming mechanism 200 to form a plate with the required thickness;

[0066] When a set of forming mechanisms 200 need to be used separately, first replace the plate surface 2002 of a set of forming mechanisms 200 with different textures on the contact surface, and then through the action of a set of first motors 2031 in the forming mechanism 200, drive the upper and lower sliding seats 230 to move horizontally synchronously, so as to move the upper forming plate 240 and the lower forming plate 250 as a whole horizontally synchronously. During use, according to the use requirements, move a set of forming mechanisms 200 to appropriate positions respectively to ensure that each forming mechanism 200 is used horizontally and separately. At this time, when the raw material passes through a set of forming mechanisms 200, different textures can be formed on the three parts of the plate body 2001 through the separate extrusion of each forming mechanism 200, and then it is conveyed to the next processing procedure by the conveyor 500. After cutting in the next processing procedure, plates with different textures are formed;

[0067] When replacing the board surface 2002 of the upper molding plate 240 or replacing the board surface 2002 of the lower molding plate 250, unscrew the screws between the board body 2001 and the board surface 2002 to remove the lower board surface 2002; when installing the board surface 2002, screw the screws into the overlapping connection holes 2005 of the board body 2001 and the board surface 2002 to fix the board body 2001 and the board surface 2002.
