Two sliding frames 4 that slide forward and backward are arranged on the mounting plate 3. The bottom ends of the sliding frames 4 are bolted with electric push rods 5. The telescopic rods of the electric push rods 5 are connected with shaping push blocks 6. A sliding frame 2 7 that slides left and right and a fixed frame 8 are provided on the mounting plate 3. The sides of the sliding frame 2 7 and the fixed frame 8 are bolted with electric push rods 2 91. The telescopic rods of the electric push rods 2 91 are fixedly connected with lifting plates 9. The bottoms of the lifting plates 9 are bolted with electric push rods 3 10. The electric push rods 3 10 The telescopic rods are fixedly connected with shaping push blocks 11, and the sides where the two shaping push blocks 16 and the two shaping push blocks 11 are close to each other are both cambered surfaces, and the four sides of the paper box 110 are shaped by the two shaping push blocks 16 and the two shaping push blocks 11; the size fine-adjustment shaping machine for paper boxes also includes a fixed column 41, a lifting block 42, a hinged rod 43, a lifting block 71 and a hinged rod 72, a fixed column 41 is welded on the top of the mounting plate 3, and the lower and upper parts of the fixed column 41 are respectively slidably connected with the lifting block 42 and the lifting block 71, two screw motors are installed on the fixed column 41, and the two screw motors drive the lifting block 42 and the lifting block 71 to move up and down respectively, and the lifting block 42 and the top of the sliding frame 4 are rotatably connected with the hinged rod 43, and the lifting block 71 and the top of the sliding frame 7 are rotatably connected with the hinged rod 72.

[0033] refer to Figure 2-Figure 5 The paper box size fine-adjustment shaping machine also includes a blocking mechanism, which includes a fixed plate 111, a fourth electric push rod 112 and a block 113. The fixed plate 111 is bolted to the left side of the mounting plate 3, and the fourth electric push rod 112 is bolted to the bottom end of the fixed plate 111. The stopper 113 is fixedly connected to the telescopic rod of the fourth electric push rod 112; the paper box size fine-adjustment shaping machine also includes a connecting plate 114, a light transmitter 115 and a light receiver 116. The front and rear parts of the mounting plate 3 are fixedly connected with the connecting plate 114, and the light transmitter 115 and the light receiver 116 are respectively installed on the two connecting plates 114. A controller is arranged on the left part of the bracket 1. The controller is a prior art, and the fourth electric push rod 112 and the light receiver 116 are electrically connected to the controller.

[0034] Initially, the light receiver 116 receives the signal sent by the light transmitter 115, and can connect to the belt conveyor of other processing procedures through the conveyor belt 2. When the paper box 110 enters from the right end of the conveyor belt 2, the initial position of the shaping push block 112 is higher than the paper box 110, and the shaping push block 112 will not block the moving paper box 110. The belt conveyor is controlled, and the conveyor belt 2 transports the paper box 110 to the left. When the paper box 110 moves between the light receiver 116 and the light transmitter 115, the light receiver 116 no longer receives the signal sent by the light transmitter 115. With the cooperation of the light receiver 116 and the controller, the controller controls the electric push rod 112 to drive the block 113 to move forward. The block 113 blocks the left rear part of the paper box 110, and the block 113 is located behind the shaping push block 112, so as not to affect the subsequent movement of the shaping push block 112, so that the paper box 110 stays between the two shaping push blocks 16.

[0035] Control the electric push rod 2 91 to drive the lifting plate 9 to descend, and drive the electric push rod 3 10 and the shaping push block 2 11 to descend, so that the two shaping push blocks 2 11 are located on the left and right sides of the paper box 110. At this time, control the electric push rod 1 5 and the telescopic rod of the electric push rod 3 10 to extend, so that the shaping push block 1 6 and the shaping push block 2 11 are moved toward the side of the paper box 110, and the four sides of the paper box 110 are shaped by the two shaping push blocks 1 6 and the two shaping push blocks 2 11, so as to fine-tune the size of the paper box 110.

[0036] Then, the telescopic rods of the electric push rod 1 5 and the electric push rod 3 10 are controlled to retract, and the electric push rod 2 91 is controlled to drive the lifting plate 9 to rise and reset, thereby driving the electric push rod 3 10 and the shaping push block 2 11 to rise and reset, so that the positions of the two shaping push blocks 2 11 are higher than the paper box 110. The controller controls the electric push rod 4 112 to drive the block 113 to move backward and reset, and the block 113 no longer blocks the paper box 110, and the conveyor belt 2 continues to convey the paper box 110 to the left. Similarly, the size of the next paper box 110 is automatically fine-tuned and shaped. In this way, the shaping process of the paper box 110 can be connected with other processes, and the degree of automation and work efficiency are high.

[0037] When it is necessary to shape paper boxes 110 of different specifications, the screw motor on the lower side is controlled to drive the lifting block 42 to descend. Under the transmission action of the hinged rod 43, the two sliding frames 4 move away from each other in the front-to-back direction, and the electric push rod 5 and the shaping push block 6 move synchronously with the sliding frame 4, and the distance between the two electric push rods 5 increases. Similarly, the screw motor on the lower side is controlled to drive the lifting block 42 to rise, and the two sliding frames 4 move closer to each other in the front-to-back direction, and the distance between the two electric push rods 5 decreases, so that the distance between the two electric push rods 5 can adapt to the distance between the front and rear sides of the paper box 110. The two shaping push blocks 6 can shape paper boxes 110 of different widths; by controlling the screw motor on the upper side to drive the lifting block 42 The lowering block 271 descends, and the sliding frame 27 slides to the right under the transmission action of the hinged rod 272. The electric push rod 291 on the right, the lifting plate 9 on the right, the electric push rod 3 10 on the right and the shaping push block 21 on the right move synchronously with the sliding frame 27, and the distance between the two electric push rods 3 10 increases. Similarly, by controlling the upper screw motor to drive the lifting block 271 to rise, the sliding frame 27 slides to the left, and the distance between the two electric push rods 3 10 decreases, so that the distance between the two electric push rods 3 10 can adapt to the distance between the left and right sides of the paper box 110. The two shaping push blocks 21 can shape paper boxes 110 of different lengths. In this way, it can automatically adapt to paper boxes 110 of different specifications, with a wide range of adaptability and high practicality.

[0038] Example 2: Based on Example 1, refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 The paper box size micro-adjusting shaping machine also includes a guiding mechanism, which includes a fixed rod 121, a guide rod 122, a limit rod 123, a limit rod 124, a rotating rod 125 and a rotating shaft 126. The front and rear sides of the top of the bracket 1 are welded with fixed rods 121, and a pair of guide rods 122 that slide forward and backward are arranged on the fixed rod 121. A limit rod 123 is fixedly connected between each pair of guide rods 122, and a limit rod 124 that slides left and right is arranged on the right end of the limit rod 123. The right part of the bracket 1 is symmetrically rotated front and back and connected with a rotating shaft 126. The two rotating shafts 126 are respectively connected to the two limit rods 122. The right ends of the two rotating rods 125 are rotatably connected with an inclined rotating rod 125, and the paper box 110 is centered in the front-to-back direction through the two rotating rods 125; the guiding mechanism also includes a connecting rod 127, a screw rod 128 and a nut 129. The top of the sliding frame 4 is fixedly connected with a connecting rod 127, and the bottom end of the connecting rod 127 is provided with a through hole. The left end of the limiting rod 123 is connected with a screw rod 128, and the two screws 128 pass through the two through holes respectively. A pair of nuts 129 are threadedly connected to the screw rod 128, and the nuts 129 are in contact with the connecting rod 127 on the same side, so that the lower end of the connecting rod 127 is clamped by the pair of nuts 129.

[0039] The distance between the two rotating rods 125 in the front-to-back direction gradually decreases from right to left. When the paper box 110 is placed on the right end of the conveyor belt 2, the two rotating rods 125 are used to center the paper box 110 in the front-to-back direction, so that the paper box 110 enters between the two limiting rods 124, and then the paper box 110 enters between the two limiting rods 123. The paper box 110 on the conveyor belt 2 is guided by the rotating rod 125, the limiting rod 124 and the limiting rod 1 123, so that the paper box 110 is smoothly conveyed between the two shaping push blocks 6, thereby preventing the paper box 110 from deviating in the front-to-back direction.

[0040] When the two sliding frames 124 move away from each other in the front-to-back direction, the sliding frame 124 drives the connecting rod 127, the nut 129, the screw rod 128, the limiting rod 123, the guide rod 122 and the limiting rod 124 to move synchronously as a whole, the distance between the two limiting rods 123 in the front-to-back direction increases, the distance between the two limiting rods 124 in the front-to-back direction increases, the limiting rod 124 will slide leftward relative to the limiting rod 123, the front rotating rod 125 rotates counterclockwise around the front rotating shaft 126 as the axis, and the rear rotating rod 125 rotates clockwise around the rear rotating shaft 126 as the axis. At this time, the rotating rod 125, the limiting rod 124 and the limiting rod 123 can adjust the paper with a larger width. The paper box 110 is guided; similarly, when the two sliding frames 4 approach each other in the front-to-back direction, the distance between the two limit rods 123 in the front-to-back direction decreases, and the distance between the two limit rods 124 in the front-to-back direction decreases, and the limit rod 124 slides to the right relative to the limit rod 123, and the front rotating rod 125 rotates clockwise with the front rotating shaft 126 as the axis, and the rear rotating rod 125 rotates counterclockwise with the rear rotating shaft 126 as the axis, so that the paper box 110 with a smaller width can be guided. In this way, when the sliding frame 4 moves to adapt to the width of the paper box 110, the positions of the rotating rod 125, the limit rod 124 and the limit rod 1 123 can be automatically and synchronously adjusted, and the synchronization is high.

[0041] If there are raised decorations on the front and rear side surfaces of the paper box 110, the second nut 129 from the front to the back is manually rotated to move the nut 129 backward relative to the front screw 128, and then the nut 129 on the front side is rotated to move the nut 129 backward relative to the front screw 128. The front pair of nuts 129 continue to clamp the lower part of the front connecting rod 127 to move the front screw 128 forward relative to the front connecting rod 127. The front screw 128 drives the front limit rod 123 and the front limit rod 2 124 to move synchronously. Similarly, by rotating the rear pair of nuts 129, the relative positions of the rear limit rod 123 and the rear connecting rod 127 can be fine-tuned to prevent the limit rod 123 from crushing the raised decorations on the side of the paper box 110, which has higher adaptability.

[0042] Embodiment 3: Based on Embodiment 2, refer to Figure 1 , Fig. 9 and Fig.10 The paper box size fine-adjusting shaping machine also includes a pushing mechanism, which includes a fixed seat 131, an electric push rod 5 132, a moving rod 133, a square rod 134, a pushing column 135 and an extrusion plate 136. The bracket 1 is fixedly connected with the fixed seat 131, and the fixed seat 131 is located at the interval between the two conveyor belts 2. The electric push rod 5 132 is bolted to the left side of the top of the fixed seat 131, and the moving rod 133 is fixedly connected to the telescopic rod of the electric push rod 5 132. The right end of the moving rod 133 is fixedly connected to the square rod 134, and the square rod 134 is provided with a pushing column 135 that slides up and down. The right side of the top of the fixed seat 131 is fixedly connected to the extrusion plate 136, and the left end of the extrusion plate 136 has an inclined surface 137. The pushing column 135 moves to the right and contacts with the inclined surface 137, thereby causing the pushing column 135 to rise through the inclined surface 137.

[0043] The telescopic rod of the electric push rod 5 132 is controlled to extend and shorten according to the interval time of placing the paper box 110. The timing control technology is the existing technology. The initial position of the push column 135 is lower than the top surface of the conveyor belt 2. When the width of the paper box 110 is too large, the paper box 110 will stay between the two rotating rods 125. At this time, the telescopic rod of the electric push rod 5 132 is controlled to extend, so that the moving rod 133, the square rod 134 and the push column 135 move to the right, and the squeezing plate 136 squeezes the push column 135 through the inclined surface 137 to move upward. The push column 135 rises to a position higher than the top surface of the conveyor belt 2, and the push column 135 will stay between the two rotating rods. The paper box 110 between the rods 125 is pushed out, and then the telescopic rod of the electric push rod 5 132 is shortened, the moving rod 133, the square rod 134 and the pushing column 135 are moved to the left and reset, and the pushing column 135 is reset by gravity. While the telescopic rod of the electric push rod 5 132 is shortened, the next paper box 110 is placed on the conveyor belt 2. If the width of the paper box 110 is not too large, the paper box 110 is smoothly conveyed to the left. If the width of the paper box 110 is too large, the telescopic rod of the electric push rod 5 132 is extended again, and the pushing column 135 pushes out the paper box 110 with a large width. In this way, the paper box 110 with a large width can be automatically pushed out, and the degree of automation is high.

[0044] Embodiment 4: Based on Embodiment 3, refer to Figure 1 , Fig. 9 and Fig.11The paper box size fine-adjusting shaping machine also includes a correction mechanism, which includes a connecting block 141, a fixed block 142, a sliding rod 143, a hinged rod three 144, a moving frame 145 and a correction block 146. The left part of the moving rod 133 is welded with a connecting block 141, and the right part of the bracket 1 is fixedly connected with a fixed block 142 symmetrically front and back. The fixed block 142 is provided with a sliding rod 143 that slides forward and backward, and the sliding rod 143 and the connecting block 141 are rotatably connected with the hinged rod three 144. The ends of the two sliding rods 143 that are close to each other are fixedly connected with a moving frame 145. The moving frame 145 is provided with a correction block 146 that slides forward and backward, and a spring is fixedly connected between the correction block 146 and the moving frame 145. The sliding connection between the correction block 146 and the moving frame 145 is provided with a damper.

[0045] When the telescopic rod of the electric push rod 5 132 is extended, the moving rod 133 and the connecting block 141 move to the right, and under the transmission action of the hinged rod 3 144, the two sliding rods 143 move away from each other in the front and rear directions, driving the two moving frames 145 to move away from each other, and the two correction blocks 146 to move away from each other. When the telescopic rod of the electric push rod 5 132 is shortened, the next carton 110 is placed on the conveyor belt 2. Similarly, the moving rod 133 and the connecting block 141 move to the left, and the two sliding rods 143 move closer to each other in the front and rear directions, driving the two moving frames 145 to move closer to each other, and the two correction blocks 146 move closer to each other and push the front and rear sides of the carton 110 to straighten the direction of the carton 110 and prevent the carton 110 from being skewed. With the cooperation of the spring and the damper, the carton 110 is prevented from being damaged, thereby preventing the carton 110 of normal width from being stuck between the two rotating rods 125, so that the direction of the carton 110 can be automatically corrected.

[0046] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
