A conveyor belt is provided on the surface of the frame, a module is provided on the gantry, and the spraying assembly is installed on the module; the spraying assembly performs reciprocating motion driven by the linear module, thereby achieving uniform spraying of the foaming agent on the conveyor belt.
[0004] A baffle is provided on one side of the gantry, and the spray port of the spray assembly is aligned with one side of the baffle; the foam is accumulated on one side of the baffle, and the accumulated foam is transported by a conveyor belt and passes through a channel between the baffle and the conveyor belt. The vertical distance between the baffle and the conveyor belt is the molding thickness of the foam sheet, and the lower end surface of the baffle serves to smooth the surface of the foam accumulation, so that the foam is initially in sheet shape.
[0005] When the foam is accumulated on the front side of the baffle, a portion of the foam will remain on one side of the baffle, so that the residue will be mixed with the new foam during the next production, resulting in impure sponge sheets. Utility Model Content
[0006] In order to facilitate the cleaning of residues on one side of the baffle, the present application provides a sponge foaming machine.
[0007] The sponge foaming machine provided in this application adopts the following technical solution:
[0008] A sponge foaming machine includes a frame, a baffle and a cleaning component.

[0016] Optionally, a pressing plate is provided in the movable groove, and the pressing plate is used to abut against one side of the film; a first spring is provided between the pressing plate and the inner wall of the movable groove, and the elastic force of the first spring is used to drive the pressing plate to move toward one side of the film.
[0017] By adopting the above-mentioned technical solution, the pressing plate maintains a tight contact with the film under the elastic force of the first spring, so that when the film is connected to the baffle, it effectively prevents the film from loosening, ensuring that the film always maintains a certain tension; and after the cutting knife cuts the film, it reduces the situation of the film detaching from the movable groove, so that the new film can be re-covered on one side of the baffle.
[0018] Optionally, the cutting board is slidably mounted with a mounting seat, and the sliding direction of the mounting seat is staggered with the extension direction of the cutting board; the mounting seat is provided with a movable hole, the cutting knife is movably mounted in the movable hole, and the support plate is provided with a positioning groove for the cutting knife to be inserted.
[0019] By adopting the above technical solution, the cutting knife is inserted into the positioning groove, which reduces the situation where the cutting knife cuts the film during the process of making the sponge sheet, and increases the stability of the cutting knife on the cutting board.
[0020] Optionally, a second spring is provided between the cutting knife and the mounting seat, and the elastic force of the second spring drives the cutting knife to be inserted into the positioning groove under normal conditions.
[0021] By adopting the above technical solution, the elastic force of the second spring can drive the cutting knife to be inserted into the positioning groove under normal conditions, further reducing the possibility of the cutting knife being detached from the positioning groove during the operation of the device.

The linear module is installed on the gantry, and the spray head is installed on the slide of the linear module; one end of the spray tube is connected to the spray head, and the other end of the spray tube is connected to an external feeding device.
[0023] By adopting the above technical solution, the linear module can drive the spray head to move back and forth, so that the spray head sprays the foam in the feeding device evenly above the frame, so that the foam forms a sheet.
[0024] In summary, this application includes at least one of the following beneficial technical effects:
[0025] 1. By providing a cleaning component, when making sponge sheets, the spray device accumulates on the side of the baffle with the film, that is, the residue is attached to the surface of the film. Therefore, when cleaning the residue on the baffle surface, it is only necessary to disconnect the film from the baffle and tear off the film with the residue. This improves the convenience of cleaning the residue on the baffle surface, reduces the need to remove the baffle from the gantry for cleaning, and improves work efficiency.
[0026] 2. By setting a pressing plate, the pressing plate maintains a tight contact with the film under the elastic force of the first spring, so that when the film is connected to the baffle, it can effectively prevent the film from loosening, ensuring that the film always maintains a certain tension; and after the cutting knife cuts the film, it reduces the situation where the film escapes from the movable groove, so that a new film can be re-covered on one side of the baffle.
