Description

Technical Field

[0001] The utility model relates to the technical field of polyester fiberboard processing, in particular to a hot pressing device for polyester fiberboard. Background Art

[0002] As we all know, polyester fiber sound-absorbing board is fully called polyester fiber decorative sound-absorbing board, which is a decorative material with sound-absorbing function made of polyester fiber as raw material through hot pressing. During processing, polyester fiber board generally needs to be hot pressed.

[0003] In real life, workers need to shape polyester fiber boards into different shapes according to needs. However, the common hot pressing device for polyester fiber boards does not have a device for cutting the burrs of the polyester fiber boards after shaping when heating and shaping the polyester fiber boards. Therefore, workers need to manually cut the burrs of the polyester fiber boards one by one, which is time-consuming and labor-intensive. Moreover, the thickness of polyester fiber boards is different. For some polyester fiber boards less than 1 cm, their thickness will decrease during hot pressing and shaping. At this time, workers need to lift the polyester fiber boards with their fingers. The contact area between the sides of the polyester fiber boards with small thickness and the fingers is small, which is not convenient for workers to lift. The device does not have a device for quickly lifting the polyester fiber boards, so its practicality is not very good and there is room for improvement. Utility Model Content

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the present invention provides a hot pressing device for polyester fiberboard, which has the following beneficial effects:

[0014] The hot pressing device for the polyester fiber board heats the shaping plate. During the shaping of the polyester fiber board, the first cutting knife and the second cutting knife will directly cut the rough edges of the polyester fiber board, thereby eliminating the need for manual cutting by staff later. When taking the cut polyester fiber board, the staff can directly grasp the extension plate and move it upward, thereby driving the pry plate to move upward and lift the polyester fiber board. At this time, the staff can directly grasp the edge of the polyester fiber board and take it out of the shaping groove. Therefore, the staff does not need to use their fingers to squeeze the side of the polyester fiber board to lift it, and the difficulty of taking out does not increase due to the small thickness of the polyester fiber board, thereby improving practicality to a certain extent.

A support plate 6 is provided in the middle of the workbench 1, and a liquid is installed in the middle of the support plate 6. The pressure cylinder 7 is provided with a heating molding plate 8 at the lower part of the hydraulic cylinder 7. When the hydraulic cylinder 7 is started, the hydraulic cylinder 7 extends, driving the heating molding plate 8 to move downward, and the lower part enters the molding groove 3 to shape the polyester fiber board. Several threaded holes are provided around the heating molding plate 8, and are all threadedly connected with bolts 9. Several bolts 9 on the left and right sides are threadedly connected with the first cutting knife 10, and several bolts 9 on the front and back sides are threadedly connected with the second cutting knife 11. The first cutting knife 10 and the second cutting knife are connected by the threaded connection between the bolts 9 and the threaded holes. The cutting knife 11 is installed on the heated molding plate 8, and then moves downward with the heated molding plate 8, enters the cutting groove 4, and cuts the burrs of the polyester fiber board after molding. When the lower parts of the first cutting knife 10 and the second cutting knife 11 are about to touch the bottom of the cutting groove 4, the heated molding plate 8 no longer believes in moving. At this time, the first cutting knife 10 and the second cutting knife 11 stop moving downward. The lower end faces of several first cutting knives 10 and second cutting knives 11 are all inclined to facilitate cutting the burrs of the polyester fiber board. Several limit stops are set around the molding block 2. Grooves 12, and all intersect with the cutting grooves 4.

An extension plate 13 is provided on the left side of the pry plate 5. Grasping the extension plate 13 and lifting it upward can drive the pry plate 5 to move upward and lift the shaped polyester fiber board. The extension plate 13 is made of a material with a high friction coefficient, which improves the stability of the staff in grasping the extension plate 13. The cross-section of the pry plate 5 is rectangular, and the pry plate 5 is prevented from rotating in the slide groove.

[0025] To sum up, when using the hot pressing device for polyester fiber board, the staff puts the polyester fiber board on the upper part of the molding groove 3 of the molding block 2, and then starts the hydraulic cylinder 7. The hydraulic cylinder 7 extends, driving the heated molding plate 8, the first cutting knife 10 and the second cutting knife 11 to move downward, and the lower part of the heated molding plate 8 enters the molding groove 3, pressing the polyester fiber board downward for molding, and at the same time, the lower parts of the first cutting knife 10 and the second cutting knife 11 cut the burrs of the polyester fiber board. When the polyester fiber board is processed, the hydraulic cylinder 7 is started, and the hydraulic cylinder 7 contracts, driving the heated molding plate 8, the first cutting knife 10 and the second cutting knife 11 to move upward, so that the lower part of the heated molding plate 8 is away from the molding block 2, and then the extension plate 13 is grasped and lifted upward, driving the pry plate 5 to move upward, and the polyester fiber board above is tilted up. Then the staff grabs the tilted polyester fiber board and takes it away from the molding block 2.
