DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0030] The following is combined with Figure 1 To Attachment Figure 4 And specific embodiments describe the present invention in detail.

[0031] like Figure 1-4 As shown, the utility model provides a hot plate bonding machine for bonding two upper and lower materials to be processed. The materials to be processed include but are not limited to pearl cotton, foam cotton, etc. The specific embodiment of this application is described by taking the bonding of two pieces of pearl cotton as an example.

[0032] The hot plate bonding machine of the present application comprises a frame 1, on which a feeding mechanism 2, a feeding mechanism 3 and a heating mechanism 4 are arranged. The feeding mechanism 2 moves horizontally below the feeding mechanism 3 and the heating mechanism 4, and is used to convey the pearl cotton thereon to the bottom of the feeding mechanism 3. The feeding mechanism 3 moves up and down above the feeding mechanism 2. The feeding mechanism 2, the feeding mechanism 3 and the heating mechanism 4 are all designed to be movable mechanisms, which is convenient for taking, heating and bonding the pearl cotton on the feeding mechanism 2; the feeding mechanism 3 comprises a feeding plate which can be moved horizontally, and the pearl cotton stacked up and down is placed on the feeding plate, and moves with the feeding plate to the bottom of the feeding mechanism 3; the heating mechanism comprises a horizontal conveying component 41, a lifting component 4 2 and a hot plate 43, the horizontal conveying assembly 41 is arranged on the frame 1, the lifting assembly 42 is arranged on the horizontal conveying assembly 41, and the hot plate 43 is arranged on the lifting assembly 42; or the lifting assembly 42 is arranged on the frame 1, the horizontal conveying assembly 41 is arranged on the lifting assembly 42, and the hot plate 43 is arranged on the horizontal conveying assembly 41; it can be understood that all structures of the hot plate 43 on the heating mechanism that can realize lifting and horizontal movements belong to the protection scope of the present application. In the specific embodiment of the present application, the horizontal conveying assembly 41 is arranged on the frame 1, the lifting assembly 42 is arranged on the horizontal conveying assembly 41, and the hot plate 43 is arranged on the lifting assembly 42 as an example for description.

[0033] It should also be noted that the present application does not limit the specific structure of the discharge mechanism 2, which may include a horizontally movable discharge plate or a circularly moving conveyor belt, on which the pearl cotton is placed and moves with the conveyor belt.

[0034] Specifically, the heating mechanism 4 includes a horizontal conveying component 41, a lifting component 42 arranged on the horizontal conveying component 41, and a heating plate 43 arranged at the lower end of the lifting component 42. The lifting component 42 moves up and down to drive the heating plate 43 to contact the lower piece of pearl cotton on the discharge plate to heat and melt the lower piece of pearl cotton, or change the vertical distance between the heating plate 43 and the discharge plate so that the heating plate 43 can preheat the lower piece of pearl cotton.

[0035] When the upper piece of pearl cotton needs to be heated and melted, the material taking mechanism 3 first descends to take away the upper piece of pearl cotton on the discharge plate, and then places the upper piece of pearl cotton on the upper surface of the hot plate 43 for heating and melting. At the same time, the distance between the hot plate 43 and the discharge plate is adjusted to a preset distance, so that the hot plate 43 can preheat the upper surface of the lower piece of pearl cotton. After the lower piece of pearl cotton is preheated, the time for the hot plate 43 to heat and melt the upper piece of pearl cotton can be appropriately reduced, so that the melting depth of the upper piece of pearl cotton is reduced, thereby improving the bonding quality of the pearl cotton; When it is necessary to heat and melt the lower piece of pearl cotton, after the material taking mechanism 3 takes the upper piece of pearl cotton, the hot plate 43 is controlled to move to the top of the lower piece of pearl cotton, and the hot plate 43 is moved downward to contact the lower piece of pearl cotton through the lifting component 42. At the same time, the material taking mechanism 3 moves downward to maintain a certain preset distance from the hot plate 43, so that the hot plate 43 can preheat the upper piece of pearl cotton. In this way, the heating and melting time of the lower piece of pearl cotton can be appropriately reduced, and the melting depth of the lower piece of pearl cotton can be reduced, thereby improving the bonding quality of the pearl cotton.

[0036] It should be noted that the present application does not limit the number of the feeding mechanism 2, the feeding mechanism 3 and the heating mechanism 4.

[0037] Specifically, the horizontal transmission assembly 41 of the embodiment of the present application is a belt transmission assembly, and two of them are arranged in parallel and spaced apart. The two belt transmission assemblies are driven to reciprocate by the first driving assembly; there are two corresponding lifting assemblies 42, which are arranged on the two belt transmission assemblies respectively, and the hot plate 43 is fixed at the lower end of the two lifting assemblies 42. The belt transmission assembly drives the two lifting assemblies 42 to move horizontally synchronously, and the two lifting assemblies 42 drive the two ends of the hot plate 43 to move up and down synchronously, thereby realizing the horizontal and lifting movement of the hot plate 43. The material picking mechanism 3 moves up and down between the two belt transmission assemblies, and the size of the material picking plate on the material picking mechanism 3 is smaller than the size of the hot plate 43, so that the material picking plate can move up and down directly above the hot plate 43. It can be understood that the belt transmission assembly is only one of the embodiments of the present application and is not limited thereto. All horizontal transmission assemblies 41 that can realize the horizontal movement of the hot plate 43 and do not interfere with the material picking mechanism 3 belong to the protection scope of the present utility model.

The first driving assembly includes a first motor 416 fixed on the frame 1, a reducer 417 drivingly connected to the motor shaft of the first motor 416, and a driving shaft 418 drivingly connected to the reducer 417.
