[0026] like Figure 2 The figure shows a packaging machine for takeout food boxes, comprising a feeding module 1, a box folding module 2, a transfer module 3, a box sealing module 4, and a frame 5. The aforementioned components are mounted on the frame 5. The frame 5 is embedded under or on the side of the stove, depending on the site conditions, leaving only the discharge port (for ejecting the box body) and the discharge port (for inserting the blank) exposed.

[0027] like Figure 3 and Figure 4As shown, the feeding module 1 includes a blank magazine, a paper rubbing belt 112, a paper separating wheel 113, a paper feeding belt 116, a guide plate 115 and a driving device; the blank magazine includes a rear top supporting plate 101, a front baffle 105 and left and right baffles 104; the rear top supporting plate 101 is provided with an adjusting device including guide rails 120, a cross beam 102, a vertical rod 121 and a hinge 103; the guide rails 120 are symmetrically installed on the left and right sides in the blank magazine, the cross beam 102 is connected with the guide rails 120 through a sliding block so that the position of the cross beam 102 can be adjusted in the front and back directions; one end of the vertical rod 121 is installed in a U-shaped groove on the cross beam 102 and the other end is connected with the rear top supporting plate 101 through the hinge 103, the vertical rod 121 can be adjusted in the left and right directions and in the up and down directions in the U-shaped groove; the hinge 103 connects the vertical rod 121 with the rear top supporting plate 101 and allows the angle of the rear top supporting plate 101 to be adjusted; the front ends of the front baffle 105 and the left and right baffles 104 are provided with L-shaped connecting pieces 119 and are installed on a first supporting beam. In the production process, the size of the blank magazine of different specifications of paper boxes can be changed by adjusting the positions of the rear top supporting plate 101 and the left and right baffles 104. The paper rubbing belt 112 is installed at the bottom of the blank magazine and directly contacts the blank in the blank magazine; the paper separating wheel 113 is installed at the rear lower end of the front baffle 105; the paper feeding belt 116 is installed in front of the paper rubbing belt 112; the power sources of the paper rubbing belt 112, the paper separating wheel 113 and the paper feeding belt 116 come from the motor 106, power distribution is realized through a transmission system, the output end of the motor 106 is connected with a worm and gear reducer 108 through a shaft coupling 107, an electromagnetic clutch 111 is installed between the worm shaft and the paper rubbing belt shaft for controlling the start and stop of the paper rubbing belt in work; a gear pair 109 is installed on the worm shaft for transmitting power to the paper feeding belt 116; a synchronous belt transmission piece 110 is installed on the worm shaft for transmitting power to the paper separating wheel 113; the guide plate includes an upper guide plate 114 and side guide plates 115, the upper guide plate 114 is installed directly above the paper feeding belt 116 and directly contacts the blank in work and provides pressure; the side guide plates 115 are symmetrically installed on the two sides of the paper feeding belt 116 for limiting the lateral deviation of the blank in the movement process; the end of the side guide plate 115 is provided with a blocking plate 117, when the front end of the blank contacts the blocking plate 117, the blocking plate 117 will stop the movement of the blank. The paper feeding belt 116 and the paper rubbing belt 112 here are conveying belts, the belt bodies have the characteristics of large friction.

[0028] In operation, the box blanks are stored in the box blank magazine, the front end of the box blank is against the front stop plate 105, the rear end is against the rear top plate 101, and the left and right ends are respectively in contact with the left and right stop plates 104. The rear top plate 101 slightly lifts the end of the box blank, so that the laminated box blank is placed obliquely in the box blank magazine. When the paper feeding starts, the paper feeding belt 112 moves the lowermost box blank in the box blank stack, and cooperates with the paper separating wheel 113 and the front stop plate 105 to block the movement of the box blanks other than the lowermost one, so as to realize the separation of the single box blank. After the separation of the box blank is completed, the electromagnetic clutch 111 is disconnected, and the paper feeding belt 112 stops running, and the paper feeding belt 116 continues to drive the box blank to move to the box folding station. In the movement process, the upper guide plate 114 can provide pressure for the paper box blank, so as to ensure the friction between the box blank and the paper feeding belt 116, and the guide rail 120 can prevent the lateral deviation of the box blank during the movement. When the box blank reaches the box folding station, the front end of the box blank is blocked by the stop plate 117, and the rear end of the box blank has been out of the pressure range of the upper guide plate 114, and the friction between the box blank and the paper feeding belt 116 is greatly reduced, so that the box blank can be temporarily stopped at the box folding station, and waits for the next process of the box folding module 2.

[0029] As Figure 5 and Figure 6As shown, the folding box module 2 comprises a punch head 210, a flange mechanism 220, and a first heat sealing mechanism 230 and a second electric push rod 240; the bottom of the punch head 210 is provided with a suction cup group 211; the flange mechanism 220 comprises a first base 224, and front and rear limiting plates 221, left and right limiting plates 222, and a bisector angle limiting rod 223 mounted on the first base 224; the first heat sealing mechanism 230 comprises a heat sealer, a first compact electric cylinder 231, and a first linkage mechanism; the mounting mode of each component is that the front and rear limiting plates 221 and the bisector angle limiting rod 223 are directly fixed and mounted above the first base 224, the left and right limiting plates 222 are movably mounted above the first base 224, and the left and right limiting plates 222 are hingedly connected with the first linkage mechanism below, and can move with the driving of the first linkage mechanism; when mounted, the height of the top of the bisector angle limiting rod 223 relative to the first base 224 is higher than that of the front and rear limiting plates 221, and is higher than that of the left and right limiting plates 222; the first compact electric cylinder 231 is mounted at the lower part of the first base 224, and the first linkage mechanism is arranged inside the first base 224, and comprises a first center rod 232, a first swing rod 234, and a first guide rod 235; the upper end of the first center rod 232 is symmetrically hingedly connected with two first swing rods 234, the other end of the first swing rod 234 is hingedly connected with the left and right limiting plates 222, the lower end of the first center rod 232 penetrates through the first base 224, is connected with the first compact electric cylinder 231 through a first connecting piece 233, and can realize the opposite movement and the back movement of the left and right limiting plates 222 through the extension and contraction of the first compact electric cylinder 231 and the driving and limitation of the first linkage mechanism. The heat sealer is also integrated on the left and right limiting plates 222, and starts to work when the left and right limiting plates 222 are clamped, so that the bisector angle structure of the box body can be immediately heat sealed and shaped. The second electric push rod 240 is mounted in the vertical direction inside the rack 5; the bottom of the second electric push rod 240 is connected with the rack 5, and the head is connected with the first base 224.

[0030] In actual production, the box blank is initially located at the end of the guide rail 120; when starting work, the first electric push rod 312 is controlled to drive the stamping head 210 to move downward until the bottom of the stamping head 210 contacts the surface of the box blank; then the suction cup group 211 adsorbs and fixes the box blank; the second electric push rod 240 is controlled to drive the baffle mechanism 220 to move upward until the bottom of the baffle mechanism 220 contacts the bottom of the box blank; in the process of upward movement of the baffle mechanism 220, the box blank bisector structure first contacts the bisector limiting rod 223, and is forced to be pre-folded by about 30° in the direction of the box; then the front and rear sides of the box blank contact the front and rear limiting plates 221, and are rotated to the vertical direction under the limiting action of the front and rear limiting plates 221; then the left and right sides of the box blank contact the left and right limiting plates 222, and are forced to be folded, thereby completing the folding of the box blank. The purpose of designing the folding sequence of the front and rear side plates and the left and right side plates of the box blank is to make the webbed feet folded inwardly close to the left and right inner walls of the paper box; then the first compact electric cylinder 231 is controlled to push out, and the left and right limiting plates 222 are driven by the first connecting rod mechanism to center and clamp the paper box until the clamping force reaches the heat sealing pressure requirement. Then the first heat sealing mechanism 230 integrated on the left and right limiting plates 222 is started to perform pulse heat sealing operation on the bisector structure of the paper box; after heat sealing, the first compact electric cylinder 231 is controlled to retract, and the left and right limiting plates 222 are released.
