Description

Technical Field

[0001] The utility model relates to the technical field of packaging printing, in particular to a printing device used for packaging printing. Background Art

[0002] Package printing is the printing process that uses various packaging materials as carriers, printing decorative patterns, designs or texts on the packaging to make the product more attractive or more descriptive, thereby conveying information and increasing sales.

[0003] In existing large-scale printing devices, for preparation before printing, the package needs to be accurately transported to the printing area. However, after reaching the bottom of the printing area, in order to ensure the accuracy of printing, the package must remain stationary for a short time. The traditional method relies on the transmission belt to complete this transportation process, that is, first placing the package on the transmission belt, and then driving the transmission belt to transport the package to the predetermined position; however, when the package needs to be stationary before printing, this method requires the transmission belt to be frequently stopped and restarted. This repeated start-up and shutdown operation not only increases the wear of the transmission belt and shortens its service life, but also increases the maintenance cost of the equipment, thereby affecting the overall production efficiency and economic benefits.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the rotating connecting rod drives the conveyor belt to rotate cyclically between the two connecting rods, driving the spring and the resistance block to move, and then pushing the support plate and the packaging bag to the printing position of the printing device. When the resistance block meets the blocking plate, it compresses the spring downward and continues to move. Then the spring resets the resistance block and pushes the support plate to continue to move forward, pushing the printed packaging bag out of the printing area. During the whole process, there is no need to stop the machine, and continuous operation can achieve continuous transportation and pause of the packaging bag, which is convenient for printing operation.

[0015] 2. In the present invention, when the friction block passes the connection between the conveyor belt and the pulley, the support plate and the packaging bag reach the end of the spacer plate, and then the device of the next process takes away the printed packaging bag, the spacer plate remains on the side of the mounting plate, and the friction block returns after passing the pulley, and pushes the L-shaped support rod to move. This drives the L-shaped slide bar and the mounting plate to slide along the slide groove, thereby pushing the support plate back to the initial position to provide support for the new packaging bag. When the friction block returns to the top of the conveyor belt again and pushes the support plate, the support plate will also push the mounting plate back to its original position to prepare for the next push.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 8 , the utility model provides a technical solution:

[0028] See also Figure 1-Figure 8As shown, a printing device for packaging printing includes a printing device 1 and a packaging bag 2, a partition plate 4 is arranged above the printing device 1, two support blocks 21 are arranged on the top of the partition plate 4, a support plate 5 is fixedly connected between the tops of the two support blocks 21, two connecting rods 11 are arranged below the partition plate 4, a plurality of pulleys 12 are fixedly installed on the outer wall of the connecting rod 11, a conveyor belt 13 is transmission-connected between the plurality of pulleys 12, a spring 15 is fixedly connected to the outer wall of the conveyor belt 13, a resistance block 16 is fixedly installed on the top of the spring 15, the packaging bag 2 is located on the top of the support plate 5, a plurality of through grooves 8 are opened in the partition plate 4, a blocking plate 7 is fixedly installed on the inner wall of the through groove 8, and the resistance block 16 is located inside the through groove 8.

[0029] One of the connecting rods 11 is rotated by hand to make it rotate, and the connecting rod 11 drives multiple pulleys 12 to rotate together, and the pulley 12 drives another connecting rod 11 and the pulley 12 to rotate through the conveyor belt 13, so that the conveyor belt 13 rotates around the two connecting rods 11, and when the conveyor belt 13 rotates, it drives the spring 15 and the resistance block 16 to move, and when the resistance block 16 moves, it pushes the support block 21 and the support plate 5 to move, so that the support plate 5 and the packaging bag 2 on the top of the support plate 5 are moved to the position responsible for printing on the printing device 1;

[0030] When the resistance block 16 moves to abut against the blocking plate 7, the resistance of the blocking plate 7 will cause the resistance block 16 to press the spring 15 downward, and then the resistance block 16 moves downward to the bottom of the blocking plate 7. At this time, the positions of the support plate 5 and the packaging bag 2 are just at the printing position on the printing device 1. After the resistance block 16 moves to the bottom of the blocking plate 7, it continues to move. When the resistance block 16 moves to the end of one end of the blocking plate 7, the blocking plate 7 will release the resistance to the resistance block 16, and then the spring 15 pushes the resistance block 16 back to its original position.

[0031] Since the length of the blocking plate 7 is smaller than that of the supporting plate 5, the resistance block 16 has pushed the supporting plate 5 to the top of the blocking plate 7 when it contacts the blocking plate 7, and one of the supporting blocks 21 far away from the resistance block 16 just passes over the blocking plate 7, so the blocking plate 7 releases the resistance to the resistance block 16, and then the spring 15 pushes the resistance block 16 back to its original position, and the resistance block 16 just bounces under the supporting plate 5 and is located on one side of one of the supporting blocks 21, and then the continuously moving resistance block 16 will push the supporting block 21 and the supporting plate 5 to move again, pushing the printed packaging bag 2 away from the printing position, and the through groove 8 provides space for the resistance block 16 to extend out of the spacer plate 4, and allows the resistance block 16 to move along the through groove 8, so that the packaging bag 2 can be stopped without stopping the machine, which is convenient for printing.

[0032] See also Figure 1-Figure 6 Two baffles 3 are installed on the top of the printing device 1, and both ends of the connecting rod 11 are rotatably connected to the outer walls of the two baffles 3 respectively.

[0033] The baffle 3 supports the connecting rod 11, making the connecting rod 11 more stable while maintaining the rotation function.

[0034] See also Figure 2 and Figure 6 One of the baffles 3 is provided with a slide groove 10, and the slide groove 10 is slidably connected with an L-shaped slide rod 19, and a mounting plate 18 is fixedly installed on the outer wall of the L-shaped slide rod 19, and the bottom end of the mounting plate 18 is against the top of the partition plate 4, and an L-shaped support rod 20 is fixedly installed on the outer wall of the L-shaped slide rod 19, and the L-shaped support rod 20 is located below the conveyor belt 13.

[0035] When the abutment block 16 moves to the connection between the conveyor belt 13 and the pulley 12, the support plate 5 and the packaging bag 2 have been pushed to the end of the partition plate 4, and then the device of the next process can take away the printed packaging bag 2, and the partition plate 4 will stay on one side of the mounting plate 18, and the abutment block 16 will move to the bottom after passing the pulley 12, and then the abutment block 16 will move back;

[0036] When the resistance block 16 contacts the L-shaped support rod 20, it will push the L-shaped support rod 20 to move, and the L-shaped support rod 20 will drive the L-shaped slide bar 19 and the mounting plate 18 to slide along the slide groove 10. When the mounting plate 18 moves, it will push the support plate 5 to move, so as to push the support plate 5 back to its original position, so that the support plate 5 can support the unprinted packaging bag 2 again. When the resistance block 16 moves back to the top of the conveyor belt 13 and pushes the support plate 5 again, since the mounting plate 18 is still located on the left side of the support plate 5, the support plate 5 will also push the mounting plate 18 back to its original position when it moves, so that the mounting plate 18 can push the support plate 5 back to the rightmost side again.

[0037] See also Figure 4-Figure 5 One side of the blocking plate 7 is set to be arc-shaped, the top of the abutment block 16 is set to be arc-shaped, and one end of the arc of the blocking plate 7 corresponds to the abutment block 16.

[0038] The arc shape of the blocking plate 7 is to facilitate the resistance block 16 to slide directly to the bottom of the blocking plate 7 after the resistance block 16 abuts against one side of the arc of the blocking plate 7. The arc shape of the resistance block 16 is also to facilitate sliding to the bottom of the blocking plate 7 to avoid the resistance block 16 being stuck on one side of the blocking plate 7.

[0039] See also Figure 3 The inner wall of the baffle 3 is rotatably connected to two support rollers 14 , and the support rollers 14 are located inside the conveyor belt 13 , and the inner wall of the conveyor belt 13 abuts against the outer wall of the support rollers 14 .

[0040] The support rollers 14 support the conveyor belt 13 to prevent the longer conveyor belt 13 from collapsing or becoming loose.

[0041] See also Figure 2-Figure 8 The partition plate 4 is provided with a plurality of slide rails 9 , and a plurality of balls 17 are rotatably connected to the bottom of the support block 21 . The balls 17 are located inside the slide rails 9 and are slidably connected to the slide rails 9 .

[0042] When the support block 21 moves along the top of the spacer plate 4 , the ball bearing 17 will slide along the slide rail 9 . The sliding of the ball bearing 17 and the slide rail 9 enables the support block 21 to move more smoothly and enables the support block 21 and the support plate 5 to be pushed more easily by the resistance block 16 .

[0043] See also Figure 6 A support rod 22 is fixedly mounted on the inner wall of the slide groove 10 , and the L-shaped slide rod 19 is slidably connected to the outer wall of the support rod 22 .

[0044] When the L-shaped slide bar 19 moves along the slide groove 10 , it will slide along the outer wall of the support rod 22 . The support rod 22 makes the L-shaped slide bar 19 more stable when moving.

[0045] See also Figure 2 One of the connecting rods 11 extends to the outside of the baffle 3 , and a servo motor 6 is provided on one side of the baffle 3 . The driving end of the servo motor 6 is connected to one end of one of the connecting rods 11 extending to the outside of the baffle 3 .

[0046] The servo motor 6 is responsible for driving one of the connecting rods 11 to rotate, and a stabilizing block for supporting the servo motor 6 is installed on the outer wall of the baffle 3 to prevent the servo motor 6 from falling or becoming loose.

[0047] Working principle:

[0048] One of the connecting rods 11 is rotated by hand to make it rotate, and the connecting rod 11 drives multiple pulleys 12 to rotate together, and the pulley 12 drives another connecting rod 11 and the pulley 12 to rotate through the conveyor belt 13, so that the conveyor belt 13 rotates around the two connecting rods 11, and when the conveyor belt 13 rotates, it drives the spring 15 and the resistance block 16 to move, and when the resistance block 16 moves, it pushes the support block 21 and the support plate 5 to move, so that the support plate 5 and the packaging bag 2 on the top of the support plate 5 are moved to the position responsible for printing on the printing device 1;

[0049] When the resistance block 16 moves to abut against the blocking plate 7, the resistance of the blocking plate 7 will cause the resistance block 16 to press the spring 15 downward, and then the resistance block 16 moves downward to the bottom of the blocking plate 7. At this time, the positions of the support plate 5 and the packaging bag 2 are just at the printing position on the printing device 1. After the resistance block 16 moves to the bottom of the blocking plate 7, it continues to move. When the resistance block 16 moves to the end of one end of the blocking plate 7, the blocking plate 7 will release the resistance to the resistance block 16, and then the spring 15 pushes the resistance block 16 back to its original position.

[0050] Since the length of the blocking plate 7 is smaller than that of the supporting plate 5, the resistance block 16 has pushed the supporting plate 5 to the top of the blocking plate 7 when it contacts the blocking plate 7, and one of the supporting blocks 21 far away from the resistance block 16 just passes over the blocking plate 7, so the blocking plate 7 releases the resistance to the resistance block 16, and then the spring 15 pushes the resistance block 16 back to its original position, and the resistance block 16 just bounces under the supporting plate 5 and is located on one side of one of the supporting blocks 21, and then the continuously moving resistance block 16 will push the supporting block 21 and the supporting plate 5 to move again, pushing the printed packaging bag 2 away from the printing position, and the through groove 8 provides space for the resistance block 16 to extend out of the spacer plate 4, and allows the resistance block 16 to move along the through groove 8, so that the packaging bag 2 can be stopped without stopping the machine, which is convenient for printing.

[0051] When the abutment block 16 moves to the connection between the conveyor belt 13 and the pulley 12, the support plate 5 and the packaging bag 2 have been pushed to the end of the partition plate 4, and then the device of the next process can take away the printed packaging bag 2, and the partition plate 4 will stay on one side of the mounting plate 18, and the abutment block 16 will move to the bottom after passing the pulley 12, and then the abutment block 16 will move back;

[0052] When the resistance block 16 contacts the L-shaped support rod 20, it will push the L-shaped support rod 20 to move, and the L-shaped support rod 20 will drive the L-shaped slide bar 19 and the mounting plate 18 to slide along the slide groove 10. When the mounting plate 18 moves, it will push the support plate 5 to move, so as to push the support plate 5 back to its original position, so that the support plate 5 can support the unprinted packaging bag 2 again. When the resistance block 16 moves back to the top of the conveyor belt 13 and pushes the support plate 5 again, since the mounting plate 18 is still located on the left side of the support plate 5, the support plate 5 will also push the mounting plate 18 back to its original position when it moves, so that the mounting plate 18 can push the support plate 5 back to the rightmost side again.
