Abstract
Description
Technical Field
[0001] This utility model relates to the field of polystyrene board technology, and in particular to a molding and testing device for polystyrene board production. Background Technology
[0002] Polystyrene foam boards with closed-cell structures are made by heating expandable polystyrene beads to pre-foam and then molding them in a mold. Due to the special nature of the material, large air bubbles may appear inside the board during the foaming process, and large pores may appear inside the board after cooling. In order to reduce the defect rate, operators will randomly inspect the finished boards, but this operation is random and the defect rate cannot be completely avoided. Utility Model Content
[0003] The purpose of this application is to provide a molding and testing device for polystyrene board production to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this application provides the following technical solution:
[0005] A molding and testing device for polystyrene board production includes a conveyor table and a testing component mounted on the conveyor table. The conveyor table consists of a conveyor belt and two side plates, which are installed on both sides of the conveyor belt. The testing component includes multiple support rods, rollers, and connecting rods. The multiple support rods are fixedly connected to form a mounting frame that is laid flat above the conveyor table. The outer wall of the mounting frame is fixedly connected to the side plates of the conveyor table. Multiple rollers are provided below each support rod. Connecting rods are installed on both sides of each roller. One end of each connecting rod is rotatably mounted on the outer wall of the support rod, and the other end is rotatably connected to the outer wall of the roller.
[0006] Preferably, a contact rod is fixedly installed on the outer wall of the connecting rod. The contact rod is a regular arc-shaped bent rod, and a sleeve is fitted onto the outer wall of the end of the contact rod. The sleeve is fixedly connected to the outer wall of the frame rod. A spring is fitted onto the outer wall of the connecting rod, with one end fixedly connected to the outer wall of the contact rod and the other end fixedly connected to the outer wall of the sleeve. A mounting plate is fixedly installed on the upper outer wall of the frame rod. A hole is opened at the end of the mounting plate, and a sensor is embedded in the hole. The sensor uses magnetic attraction. The sensor is installed along the movement path of the contact rod, and a baffle made of magnet is fixedly installed at the end of the contact rod.
[0007] The beneficial effects of this utility model are: by setting up a detection component, the thickness of the plate can be detected by observing the contact between the contact rod and the sensor, and at the same time, the roller applies pressure to the surface of the plate to detect the overall strength of the plate.

[0011] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0012] like Figure 1-2 The invention shown is a molding and testing device for polystyrene board production, including a conveyor table 1 and a testing component installed on the conveyor table 1. The conveyor table 1 consists of a conveyor belt and side plates. Two side plates are provided and installed on both sides of the conveyor belt. The testing component includes multiple support rods 2, rollers 3 and connecting rods 4. Multiple support rods 2 are fixedly connected to form a mounting frame and are laid flat above the conveyor table 1. The outer wall of the mounting frame is fixedly connected to the side plates of the conveyor table 1. Multiple rollers 3 are provided below each support rod 2. Connecting rods 4 are installed on both sides of each roller 3. One end of the connecting rod 4 is rotatably installed on the outer wall of the support rod 2, and the other end is rotatably connected to the outer wall of the roller 3.
[0013] A contact rod 5 is fixedly installed on the outer wall of the connecting rod 4. The contact rod 5 is a regular arc-shaped bent rod. A sleeve 7 is fitted onto the outer wall of the end of the contact rod 5, and the sleeve 7 is fixedly connected to the outer wall of the frame rod 2. A spring 6 is fitted onto the outer wall of the connecting rod 4. One end of the spring 6 is fixedly connected to the outer wall of the contact rod 5, and the other end is fixedly connected to the outer wall of the sleeve 7. A mounting plate 8 is fixedly installed on the upper outer wall of the frame rod 2. A hole is opened at the end of the mounting plate 8, and a sensor 9 is embedded in the hole. The sensor 9 uses magnetic attraction induction. The sensor 9 is installed on the movement path of the contact rod 5, and a baffle 10 is fixedly installed at the end of the contact rod 5. The baffle 10 is made of magnet.
[0014] Example: The cut polystyrene board is transferred from the cutting station to the conveyor table 1. The board is pushed by the conveyor belt, and the board pushes the roller 3 on the support rod 2. The roller 3 rolls on the board, and at the same time, the roller 3 drives the connecting rod 4 to rotate upward at a certain angle. When the connecting rod 4 rotates, the contact rod 5 is driven to rotate upward at a certain angle. The contact rod 5 slides in the sleeve 7, and the spring 6 is compressed and deformed. The sleeve 7 provides a moving guide for the contact rod 5. The baffle 10 at the end of the contact rod 5 is attracted to the sensor 9 at the end of the mounting plate 8. Since the thickness of the board is fixed, the upward rotation angle of the connecting rod 4 is fixed, and the baffle 10 is attracted to the sensor 9.
[0015] If the thickness of the board meets the standard, multiple sensors 9 on the support rod 2 will emit electrical signals. As the board passes through the conveyor table 1, the production line control terminal receives all the electrical signals and determines that the board thickness and surface strength meet the standards. Because multiple springs 6 provide a reaction force to the connecting rod 4, the roller 3 applies downward pressure to the board surface. If there are internal defects in the board or the surface is not strong enough, the reaction force of the springs 6 will cause the roller 3 to leave marks or even dents on the board surface. If the roller 3 presses too hard on the board surface, it means that the rotation angle of the connecting rod 4 is insufficient, and the baffle 10 at the end of the contact rod 5 does not contact the sensor 9, so no electrical signal is emitted. Since the production line control terminal does not receive sufficient electrical signals, it will stop the operation of the conveyor table 1, and the operator will inspect the defective board.
[0016] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.
[0017] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
