[0043] During the bonding process, the base film passes through the second limiting roller 36 and the foam passes through the first limiting roller 35. The first limiting roller 35 and the second limiting roller 36 move synchronously to limit the foam and the base film to prevent the base film or foam from running off the track, resulting in bonding misalignment or wrinkles.

[0044] Furthermore, if Figure 4As shown, a bidirectional ball screw 37 is rotatably connected between the two second fixing plates 3 via a bearing, and the connecting plate 33 is symmetrically threadedly connected to the bidirectional ball screw 37; a driving motor 39 is fixedly connected to the outer wall of the second fixing plate 3, and the output shaft of the driving motor 39 is fixedly connected to one end of the bidirectional ball screw 37; two guide rods 38 are fixedly connected between the two second fixing plates 3, and the connecting plates 33 are both slidably connected to the guide rods 38.

[0045] The bidirectional ball screw 37 provided by the present invention is used to adjust the positions of the first limiting roller 35 and the second limiting roller 36 when in use. By turning on the first driving motor 39, the bidirectional ball screw 37 is driven to rotate by the output shaft of the driving motor 39, and the connecting plate 33 is driven to move toward the center at the same time by the bidirectional ball screw 37. The first fixed seat 32 and the second fixed seat 34 are driven to move toward the center at the same time by the connecting plate 33. The first limiting roller 35 and the second limiting roller 36 are driven to move toward the center at the same time by the first fixed seat 32 and the second fixed seat 34. The foam and the bottom film are limited by the first limiting roller 35 and the second limiting roller 36 to prevent the foam or the bottom film from deviating.

[0046] Furthermore, if Figure 1 As shown, two first fixed plates 2 are fixedly connected to the top of the frame 1, and a bottom film unloading roller 21 is rotatably connected between the two first fixed plates 2 via a bearing; one end of the bottom film unloading roller 21 is extended and fixedly connected with a first rotating wheel 22, one end of the composite roller 12 close to the bottom film unloading roller 21 is extended and fixedly connected with a second rotating wheel 24, and a belt 23 is sleeved between the second rotating wheel 24 and the first rotating wheel 22; the other end of the bottom film unloading roller 21 is provided with a driving mechanism.

[0047] When the first rotating wheel 22 and the second rotating wheel 24 provided by the present invention are in use and loading, the driving mechanism is turned on, and the driving mechanism drives the bottom film feeding roller 21 to rotate, and the bottom film feeding roller 21 drives the first rotating wheel 22 to rotate, and the first rotating wheel 22 drives the belt 23 to rotate, and the belt 23 drives the second rotating wheel 24 to rotate, and the second rotating wheel 24 drives the connected composite roller 12 to rotate, thereby realizing the linkage between the bottom film feeding roller 21 and the composite roller 12, and a chain is provided between the composite rollers 12, so that the composite rollers 12 rotate synchronously, which is convenient for rapid loading.

[0048] Furthermore, if Figure 1 and Figure 6As shown, a pressure roller 91 is provided above the composite roller 12 away from the bottom film discharge roller 21, and two mounting seats 9 are fixedly connected to the top of the frame 1. A reciprocating screw 93 is rotatably connected to the mounting seat 9 through a bearing, and a moving block 92 is threadedly connected to the reciprocating screw 93. Both ends of the pressure roller 91 are rotatably connected to the moving block 92 through bearings, and a rotating block 94 is fixedly connected to the top of the reciprocating screw 93; a first pressure sensor 121 is provided at the bearing of the composite roller 12.

[0049] The pressure roller 91 provided by the present invention is used to adjust the pressure of the foam when in use. When the release film is adhered to the surface of the foam, it is necessary to rotate the rotary block 94, and the reciprocating screw 93 is driven to rotate by the rotary block 94, and the moving block 92 is driven to move up and down by the reciprocating screw 93, and the pressure roller 91 is driven to move by the moving block 92, and the release film and foam are pressed by the pressure roller 91, and the composite roller 12 is pressed by the release film and foam. At this time, the first pressure sensor 121 on the composite roller 12 monitors the pressure state, and when the first pressure sensor 121 reaches the set value, it stops rotating to realize the function of quickly adjusting the foam pressure.

[0050] Furthermore, if Figure 2 and Figure 7 As shown, a second vertical plate 17 is fixedly connected to the bottom of one end of the frame 1, and a winding roller 171 is rotatably connected to the second vertical plate 17 through a bearing, and a movable plate 183 is sleeved on the other end of the winding roller 171; an electric push rod 18 is fixedly connected to the side wall of the frame 1, and a movable seat 181 is fixedly connected to the output end of the electric push rod 18, and two limit openings 182 are provided on the movable seat 181, and two limit blocks 184 are fixedly connected to the top of the movable plate 183, and the limit blocks 184 are matched with the limit openings 182; two grooves are provided on the side wall of the frame 1, and two fixing rods 185 are fixedly connected in the grooves, and the limit blocks 184 are inserted on the fixing rods 185; a second pressure sensor 186 is provided on the movable plate 183, and the second pressure sensor 186 is arranged on the inner side of the bearing of the winding roller 171.

[0051] The second pressure sensor 186 provided by the present invention is used to control the weight of the foam rolled on the winding roller 171 when in use. After the foam is bonded, it needs to be rolled up. When the second pressure sensor 186 reaches the set value, the driving mechanism stops working and the electric push rod 18 is turned on. The electric push rod 18 moves the limit opening 182 on the movable seat 181 through the output end to align with the limit block 184, and then moves the limit block 184 into the limit opening 182 through the movable plate 183. Finally, the movable plate 183 is moved to one side through the electric push rod 18, and the foam on the winding roller 171 can be removed; during installation, it is necessary to move the limit opening 182 on the movable seat 181 through the electric push rod 18 to align with the groove, move the movable plate 183 to the fixed rod 185, and finally move the limit opening 182 on the movable seat 181 through the electric push rod 18 to be misaligned with the limit block 184.

[0052] Furthermore, if Figure 1 and Figure 5 As shown, two fourth fixed plates 5 are fixedly connected to the top of the frame 1, and an adhesive roller 54 is provided between the fourth fixed plates 5. The adhesive roller 54 is arranged between the second dust removal roller 41 and the protective film receiving roller 61. The fourth fixed plates 5 are fixedly connected with sliding columns 52, and the sliding columns 52 are slidably connected with sliders 51. The two ends of the adhesive roller 54 are respectively rotatably connected to the sliders 51 through bearings, and the outer sides of the sliding columns 52 are respectively sleeved with springs 53, and the two ends of the springs 53 are respectively fixed to the sliders 51 and the fourth fixed plates 5.

[0053] The spring 53 provided by the present invention is convenient for adjusting the height of the bonding roller 54 when in use. When the foam is bonded to the base film, it passes through the bonding roller 54. Under the action of the spring 53 and its own gravity, the bonding roller 54 can be adjusted up and down, so as to facilitate the bonding of foams of different thicknesses.

[0054] Furthermore, if Figure 3 As shown, two sixth fixed plates 7 are fixedly connected to the top of the frame 1, and the top of the sixth fixed plate 7 is rotatably connected to a transparent film unloading roller 71 through a bearing. Two side plates 72 are fixedly connected to the top of the frame 1, and the top of the side plate 72 is rotatably connected to a transparent film paper receiving roller 73 through a bearing. The sixth fixed plate 7 and the side plate 72 are sequentially arranged on one side of the fifth fixed plate 6.

[0055] When the transparent film unloading roller 71 and the transparent film paper collecting roller 73 provided by the present invention are in use, a layer of transparent film needs to be adhered to the surface of the foam to facilitate the bonding of the release film and the foam. There is transparent film paper on the surface of the transparent film, which needs to be automatically collected by the transparent film paper collecting roller 73 to facilitate the continuity of bonding.

[0056] Furthermore, if Figure 3As shown, a first support rod 13 and two second support rods 14 are rotatably connected between the inner side walls of the frame 1, the first support rod 13 is arranged between the second dust removal roller 41 and the bonding roller 54, and is arranged above the foam; the second support rods 14 are respectively arranged on both sides of the transparent film discharge roller 71.

[0057] The present invention provides a first support rod 13 and a second support rod 14. When in use, the first support rod 13 is used to guide and support the foam to prevent the foam from being directly attached to the base film without being limited; the second support rod 14 is used to guide and support the transparent film to facilitate the peeling of the paper on the transparent film and the attachment of the transparent film to the foam.

[0058] Furthermore, if Figure 2 As shown, two seventh fixed plates 8 are fixedly connected to the top of the frame 1, and the seventh fixed plates 8 are arranged on one side of the side plate 72. A release film discharge roller 81 is rotatably connected between the two seventh fixed plates 8 through a bearing, and a release film limiting mechanism is provided under the two first fixed plates 2, and the release film limiting mechanism has the same structure as the limiting mechanism.

[0059] The release film discharge roller 81 provided by the present invention is used for discharging the release film when in use. A release film limiting mechanism is set, wherein the first limiting roller 35 is used to limit the release film, and the second limiting roller 36 is used to limit the semi-finished product after the base film, foam and transparent film are bonded together, so as to facilitate the alignment and limiting of the release film and the semi-finished product.

[0060] Furthermore, if Figure 1 As shown, two first vertical plates 16 are fixedly connected to the bottom of the frame 1, and a waste material receiving roller 161 is rotatably connected between the two first vertical plates 16. The waste material receiving roller 161 is arranged between the winding roller 171 and the pressure roller 91.

[0061] When the waste material receiving roller 161 provided by the present invention is in use, a protective film is provided on the surface of the base film, which needs to be peeled off before winding up, so that when winding up, the base film can be wound on the inside and the release film can be wound on the outside, which is convenient for storage and transportation.

[0062] Working principle: first fix the foam on the foam discharge roller 31, place the bottom film on the bottom film discharge roller 21, place the transparent film on the transparent film discharge roller 71, and place the release film on the release film discharge roller 81; then the base passes through five composite rollers 12 in turn, and the foam passes through the second dust removal roller 41 in turn to remove dust from the bottom, and the protective film collection roller 61 collects the protective film on the surface of the outer layer, passes through the first dust removal roller 15 to remove dust from the top, and then passes through the composite film in turn, first laminating with the bottom film, then laminating with the transparent film, and finally laminating with the release film, thereby completing the lamination of the foam, wherein the first dust removal roller 15 and the second dust removal roller 41 are used to clean the dust on the surface of the foam to prevent the presence of dust It may hinder the close contact between the foam and the surface to be bonded, resulting in loose bonding; it may form defects such as white spots and foreign matter, affecting the appearance quality of the product; in the bonding process, by turning on the first drive motor 39, the output shaft of the drive motor 39 drives the bidirectional ball screw 37 to rotate, and the bidirectional ball screw 37 drives the connecting plate 33 to move toward the center at the same time, and the connecting plate 33 drives the first fixed seat 32 and the second fixed seat 34 to move toward the center at the same time, and the first fixed seat 32 and the second fixed seat 34 drive the first limiting roller 35 and the second limiting roller 36 to move toward the center at the same time, and the foam and the bottom film are limited by the first limiting roller 35 and the second limiting roller 36 to prevent the foam or the bottom film from running off, resulting in misalignment or wrinkles in the bonding;

[0063] When the release film is attached to the surface of the foam, it is necessary to rotate the rotary block 94, and the reciprocating screw 93 is driven to rotate by the rotary block 94, and the moving block 92 is driven to move up and down by the reciprocating screw 93, and the pressure roller 91 is driven to move by the moving block 92, and the release film and foam are pressed by the pressure roller 91, and the composite roller 12 is pressed by the release film and foam. At this time, the first pressure sensor 121 on the composite roller 12 monitors the pressure state, and when the first pressure sensor 121 reaches the set value, the rotation is stopped to realize the function of quickly adjusting the foam pressure; after the foam is pasted, it needs to be rolled up, and when the second pressure sensor 186 reaches the set value, the driving mechanism stops working. The operation is to turn on the electric push rod 18, and the electric push rod 18 moves the limit opening 182 on the movable seat 181 through the output end to align with the limit block 184, and then moves the limit block 184 into the limit opening 182 through the movable plate 183, and finally moves the movable plate 183 to one side through the electric push rod 18, so that the foam on the winding roller 171 can be removed; during installation, it is necessary to move the limit opening 182 on the movable seat 181 through the electric push rod 18 to align with the groove, move the movable plate 183 to the fixed rod 185, and finally move the limit opening 182 on the movable seat 181 through the electric push rod 18 to be misaligned with the limit block 184.
