[0036] Foam is a material made of foamed plastic particles, referred to as foam. Foam has a series of characteristics such as elasticity, light weight, rapid pressure-sensitive fixation, easy use, easy bending, ultra-thin volume, and reliable performance. The thickness of foam is relatively thin. In order to obtain a foam product with thicker thickness and better performance, it is often necessary to laminate two foams together.

[0037] The existing foam composite device rolls the foam through a pressure roller. When the composite material is softer than the foam material, the foam will be squeezed by the pressure roller, so that the foam material will become thinner and lose the foam thickness. The foam after rolling cannot meet the thickness size requirements.

[0038] The following is combined with Figures 1 to 7 The utility model is described in further detail.

[0039] Reference Figures 1 to 3As shown, the composite rolling device includes a first side plate 100, a driving assembly 200, a first roller 300, a second roller 310 and a composite roller 320. There are two first side plates 100, which are symmetrically arranged. A pin hole is opened at the bottom of the first side plate 100. The pin hole cooperates with the pin to position the first side plate 100 on the workbench. A driving assembly 200 is arranged on one side of the first side plate 100. The driving assembly 200 includes a motor 210 and a reducer 220. The motor 210 is connected to the reducer 220. The first roller 300 is located between the two first side plates 100. The first roller 300 is arranged horizontally. The motor 210 The first roller 300 is connected to the second roller 310 through the reducer 220. The reducer 220 matches the rotational speeds of the motor 210 and the first roller 300 and transmits the torque of the motor 210 to the first roller 300. The second roller 310 is also located between the two first side plates 100 and above the first roller 300. The second roller 310 is meshed with the first roller 300 for transmission, that is, the second roller 310 can rotate synchronously with the first roller 300 under the drive of the driving assembly 200. The composite roller 320 is rotatably disposed between the two first side plates 100. The composite roller 320 is located above the second roller 310. It can also be understood that the first roller 300, the second roller 310 and the composite roller 320 are parallel to each other and are arranged in sequence from bottom to top. The composite roller 320 and the second roller 310 are horizontal to each other and leave a certain gap. The outer surface of the composite roller 320 is provided with a milling groove 321. The foam is completely located in the gap between the milling groove 321 and the second roller 310. The foam abuts against the bottom surface of the milling groove 321 of the composite roller 320 and the outer surface of the second roller 310, and is compounded under the extrusion of the composite roller 320 and the second roller 310.

[0040] It should be noted that, by opening a milling groove 321 on the composite roller 320, a second roller 310 and a first roller 300 are provided below the composite roller 320, and the driving component 200 arranged on the first side plate 100 drives the first roller 300 to rotate, thereby driving the second roller 310 to rotate. Since the foam abuts against the bottom surface of the milling groove 321 of the composite roller 320 and the outer surface of the second roller 310 during the composite process, there is a certain gap between the bottom surface of the milling groove 321 and the outer surface of the second roller 310, and the foam is located in the gap. The foam is compounded under the extrusion of the composite roller 320 and the second roller 310. The foam with a relatively soft material can reduce the thickness loss of the foam during composite, so that the foam after rolling can meet the thickness size requirements.

[0041] It is understandable that in some embodiments of the present invention, reference Figure 3As shown, the material of the outer layer of the composite roller 320 is ethylene-vinyl acetate copolymer (EVA). Ethylene-vinyl acetate copolymer is a general polymer composed of monomers such as ethylene and vinyl acetate. It has good elasticity, plasticity and chemical corrosion resistance, and is a material widely used in product manufacturing and engineering construction. Ethylene-vinyl acetate copolymer is sleeved on the steel core 322 of the composite roller 320 to form the outer layer of the composite roller 320. The hardness of ethylene-vinyl acetate copolymer is 25 degrees. The milling groove 321 is opened in the ethylene-vinyl acetate copolymer layer of the composite roller 320. The hardness of ethylene-vinyl acetate copolymer is 25 degrees. Ethylene-vinyl acetate copolymer is relatively soft, similar to the softness of rubber, and can provide good shock absorption and comfort. Ethylene-vinyl acetate copolymer is used as the outer layer of the composite roller 320, and a processing groove is milled in the outer layer using a CNC machine tool for extruding composite foam. The soft outer layer of the composite roller 320 extrudes the foam, which can reduce the loss of foam thickness during the composite process.

[0042] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 3 As shown, the depth of the milling groove 321 of the composite roller 320 is 0.1 mm to 2 mm. The composite roller 320 with the milling groove 321 of 0.1 mm depth cooperates with the second roller 310 to process thinner foam. The composite roller 320 with the milling groove 321 of 2 mm depth cooperates with the second roller 310 to process thicker foam. Composite foams with different thickness requirements can be processed by composite rollers 320 with different milling groove 321 depths, so that the processed foam meets the thickness size requirements.

[0043] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 3 As shown, the width of the milling groove 321 is larger than the width of the foam to be composited. This arrangement allows the foam to be completely located in the milling groove 321, so that the foam can be completely squeezed by the composite roller 320 and the second roller 310 during the composite processing, thereby processing a composite foam that meets the processing requirements.

[0044] It is understandable that in some embodiments of the present invention, reference Figure 1 , Figure 4 and Figure 7As shown, it also includes a slider 500, which is provided with bearings. Both ends of the second roller 310 and the compound roller 320 are connected to the slider 500 and can rotate freely through the bearings of the slider 500. The first side plate 100 is provided with a slide groove 111. The size of the slider 500 matches the size of the slide groove 111. The slider 500 can slide along the length direction of the slide groove 111, that is, the second roller 310 and the compound roller 320 can slide in the vertical direction.

[0045] It is understandable that in some embodiments of the present invention, reference Figure 1 , Figure 4 and Figure 7 As shown, an abutment portion 510 is provided on one side of the slider 500. The abutment portion 510 is a rib extending from the slider 500 in a direction away from the slider 500. The abutment portion 510 can abut against the opposite side of the two first side plates 100. The abutment portion 510 can prevent the slider 500 from slipping out of the slide groove 111 of the first side plate 100 during sliding, and at the same time, the second roller 310 and the composite roller 320 are confined between the two first side plates 100, thereby preventing the workpiece from shifting during composite processing and improving the processing accuracy.

[0046] It should be noted that, in other embodiments, referring to Figure 1 , Figure 5 and Figure 7 As shown, abutment portions 510 are provided on both sides of the slider 500, and the abutment portions 510 on both sides of the slider 500 abut against the first side plate 100, which can completely prevent the slider 500 from slipping out of the slide groove 111, and provide support force for the slider 500 during the sliding process, thereby improving the stability of the slider 500 when sliding.

[0047] It is understandable that in some embodiments of the present invention, reference Figure 1As shown, a pressure block 600 is provided above the slider 500, and the bottom of the pressure block 600 can be abutted against the top of the slider 500. The pressure block 600 is connected to a pressure rod 610, and the pressure rod 610 is a screw. A fixing block 700 is provided on the top of the first side plate 100, and a screw hole is opened in the fixing block 700, and the pressure rod 610 is rotatably set in the screw hole. When the pressure rod 610 rotates, since the fixed block 700 is fixed to the first side plate 100, the pressure rod 610 will move in the vertical direction. Because the pressure block 600 is connected to the pressure rod 610, the pressure block 600 and the pressure rod 610 move synchronously in the vertical direction. When the pressure block 600 moves downward to a certain height along with the pressure rod 610, the bottom of the pressure block 600 abuts against the top of the slider 500, thereby limiting the height of the slider 500. The composite roller 320 and the second roller 310 process the foam, and the composite roller 320 will be subjected to the upward reaction force of the foam on the composite roller 320. The pressure block 600 can limit the upward movement distance of the composite roller 320, thereby improving the stability during foam processing.

[0048] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 7 As shown, the slider 500 is provided with a protrusion 400, which is fixed to the side of the slider 500 by screws. The protrusion 400 extends in the direction away from the first side plate 100, and the protrusion 400 can serve as a handle. When it is necessary to disassemble or replace the composite roller 320 or the second roller 310, the fixing block 700 and the pressing block 600 are first removed, and then the protrusion 400 is held with both hands, and the composite roller 320 or the second roller 310 is slid upward and pulled out from the slide groove 111 in the first side plate 100, so as to perform maintenance or replace parts, and the operation is simple and quick.

[0049] It is understandable that in some embodiments of the present invention, reference Figure 1 As shown, a second side plate 110 is connected between the two first side plates 100. The second side plate 110 is provided with a countersunk hole. The composite rolling device can be fixed on the workbench through the second side plate 110, and the second side plate 110 can strengthen the strength between the two first side plates 100, prevent the composite rolling device from being deformed during processing, and enhance the processing stability of the composite rolling device.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
