DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 6The device for continuously printing box surface labels shown in the figure comprises a base frame 1, a feeding trolley 2 and a laser marker 4. Two feeding trolleys 2 are movably installed on the base frame 1. One feeding trolley 2 is equivalent to an operation station. Therefore, the present invention is designed with double stations to meet the production operation requirements. The feeding trolley 2 is provided with a box slot 21. The size of the box slot 21 matches the size of the packaging box to be printed. The packaging box can be placed in the box slot 21. The base frame 1 is installed with a power mechanism 3. The power mechanism 3 is transmission-connected with the two feeding trolleys 2. The reciprocating motion of the two feeding trolleys 2 can be controlled simultaneously by the power mechanism 3. The base frame 1 is provided with a forward direction end 11 and a return direction end 12. The laser marker 4 is installed at the forward direction end 11. The driving of the power mechanism 3 can make the two feeding trolleys 2 alternately enter the laser marker 4 area to complete the box surface label printing operation. Two There are two symmetrically arranged trolley running rails 13, and two delivery trolleys 2 are movably installed on the two trolley running rails 13 respectively. When one delivery trolley 2 moves to the forward direction end 11, the other delivery trolley 2 moves to the return direction end 12. When the delivery trolley 2 moves to the forward direction end 11, it can cooperate with the laser marker 4 to complete the label printing operation. When the delivery trolley 2 moves to the return direction end 12, the packaging box can be replaced (the replacement can be done manually or by a robot). The present invention reasonably arranges the positions of the two delivery trolleys 2, one is just for label printing operation, and the other is just for packaging box replacement operation. With the alternating movement of the two delivery trolleys 2, continuous label printing operation can be realized, the operation waste time is greatly reduced, the operation efficiency is greatly improved, and the needs of enterprises for printing labels in large quantities can be well met.

[0024] like Figure 4 As shown, the power mechanism 3 includes a motor 31, a passive pulley 33 and a transmission belt 34. The motor 31 is installed at the return direction end 12, the output end of the motor 31 is connected to the active pulley 32, and the passive pulley 33 is rotatably installed at the forward direction end 11, as shown in FIG. Figure 6 As shown, the driving pulley 32 and the driven pulley 33 are driven by a transmission belt 34. When the motor 31 is started, the movement effect of the transmission belt 34 can be formed, such as Figure 3 and Figure 4 As shown, the transport trolley 2 is equipped with a belt link plate 222, which is fixedly connected to the belt surface of the transmission belt 34. As the transmission belt 34 moves, the transport trolley 2 will also be dragged in a straight line, such as Figure 2 As shown, two plate slots 14 are provided on the base frame 1, and the link plate 222 moves in the plate slots 14. The plate slots 14 are provided to facilitate the movement of the link plate 222. At the same time, the length of the plate slots 14 also determines the forward and return limit positions of the delivery trolley 2. When the delivery trolley 2 reaches the forward limit position, the box slot 21 falls just below the laser marker 4, which can accurately complete the box surface label printing operation.

[0025] like Figure 4 As shown, a base 41 is provided below the laser marker 4, the base 41 is mounted across the base 1, the laser marker 4 is fixedly mounted on the base 4, and the laser marker 4 is correspondingly arranged on the central axis of the width side of the base 1. As can be seen from the above content, the laser marker 4 adopts a fixed position installation mode, and the central axis of the width side of the base 1 is Figure 1 The dotted line in Figure 1 It can be seen that the laser marker 4 is exactly in the center. Since the present invention adopts double trolleys for feeding, the two delivery trolleys 2 will have motion interference during the movement. How to solve this problem is a difficult point in design.

[0026] In view of the above situation, if Figure 5 As shown, the delivery trolley 2 of the present invention is designed to include a bottom car 22 and a delivery platform 23. A slider 221 is connected to the bottom of the bottom car 22. The bottom car 22 is movably installed on the trolley running rail 13 through the slider 221. The bottom car 22 moves linearly along the length direction of the trolley running rail 13, that is, a linear reciprocating motion between the forward direction end 11 and the return direction end 12. The delivery platform 23 is installed on the bottom car 22. Since the delivery platform 23 has a large area, if it only moves linearly with the bottom car 22, the delivery platforms 23 of the two delivery trolleys 2 will collide during the reciprocating process. Therefore, the present invention is paved with a platform slide rail 223 on the top surface of the bottom car 22. The platform slide rail 223 is arranged perpendicular to the trolley running rail 13, and the delivery platform 23 is movably installed on the platform slide rail 223, so that the delivery platform 23 can do lateral borrowing motion relative to the bottom car 22, such as Figure 2 and Figure 3 As shown, the base frame 1 is provided with a platform driving groove 15 on the side of the trolley running rail 13, and the bottom surface of the delivery platform 23 is connected with a connecting rod 231. The bottom of the connecting rod 231 is rotatably installed with a driving wheel 232, and the driving wheel 232 is matched and installed in the platform driving groove 15. The driving wheel 232 can slide along the platform driving groove 15. With the change of the shape of the platform driving groove 15, the effect of driving the delivery platform 23 to move horizontally can be formed, such as Figure 2As shown, the platform driving groove 15 is provided with two first straight segments 151 and a second straight segment 152, the second straight segment 152 is located in the middle of the platform driving groove 15, the two first straight segments 151 are connected to the two ends of the second straight segment 152, the first straight segment 151 and the second straight segment 152 are parallel to the trolley running rail 13, the distance between the second straight segment 152 and the trolley running rail 13 is greater than the distance between the first straight segment 151 and the trolley running rail 13, that is, the second straight segment 152 is far away from the trolley running rail 13, and the first straight segment 151 is close to the trolley running rail 13. The structure designed in this way is that when the driving wheel 232 moves along the first straight segment 151, the delivery platform 23 is closer to the trolley running rail 13, and the delivery platform 23 is provided with a box groove 21, which is just on the central axis of the width side of the base frame 1, so that the box groove 21 can be smoothly and accurately Only when the two carriages 2 come to the right below the laser marker 4 can the label printing operation be successfully completed. During the alternating reciprocating motion of the two carriages 2, the two carriages 2 intersect. The present invention designs the intersection period when the driving wheel 232 moves along the second straight segment 152. At this time, the delivery platforms 23 on the two carriages 2 are just in a lateral borrowing movement state. Therefore, the two carriages 2 can just intersect and pass, which perfectly solves the problem of motion interference between the carriages 2. In the present invention, the two carriages 2 are installed in a mirror image, and the platform driving grooves 15 are symmetrically opened, so that the two carriages 2 can simultaneously form the effect of borrowing movement outward. The two carriages intersect in the second straight segment 152. After the intersection, the label printing operation is to be carried out. Therefore, the second straight segment 152 is immediately connected to the first straight segment 151, so that the box slot 21 returns to the central axis of the width side of the base frame 1.

[0027] like Figure 3 As shown, an avoidance groove 224 is provided on the bottom vehicle 22 to facilitate the movement of the connecting rod 231 along the avoidance groove 224 . This design can solve the problem of movement interference between the connecting rod 231 and the bottom vehicle 22 .

[0028] like Figure 4 As shown, the link plate 222 is fixedly connected to the bottom vehicle 22, the power mechanism 3 directly forms the movement effect of the bottom vehicle 22, and the lateral movement effect of the delivery platform 23 is the effect of the linked movement, such as Figure 6 As shown, the connecting plates 222 on the two delivery trolleys 2 are staggered, one is connected to the forward direction end 11, and the other is connected to the return direction end 12. In this way, with the movement of the transmission belt 34, the alternating reciprocating motion effect of the two delivery trolleys 2 can be achieved. The motor 31 in the present invention needs to be started alternately in forward and reverse directions, so as to drive the transmission belt 34 to move alternately in forward and reverse directions.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
