Description

Technical Field

[0001] This utility model relates to the technical field of paper box printing, and in particular to an auxiliary flattening mechanism for cold foil stamping transfer of pharmaceutical packaging boxes. Background Technology

[0002] Cold foil stamping transfer technology transfers patterns from a transfer film to the surface of a substrate by pressing at room temperature and curing with an adhesive. It is a process that can transfer decorative effects such as patterns and text without high temperature. Compared with traditional hot foil stamping technology, it has the characteristics of low energy consumption and wide adaptability, and is widely used in packaging printing, electronic components, handicrafts and other fields.

[0003] In existing technologies, when printing pharmaceutical packaging boxes, the boxes need to be flattened to improve printing quality. Various auxiliary flattening mechanisms for cold foil stamping transfer of pharmaceutical packaging boxes are disclosed in the prior art. For example, Chinese utility model patent CN219294995U discloses an auxiliary flattening mechanism for cold foil stamping transfer of pharmaceutical packaging boxes. This flattening mechanism includes a support frame, a conveyor belt inside the support frame, and a fixed frame fixedly connected to the top of the support frame. Two pressing plates are located on the top of the conveyor belt. A moving component for moving the pressing plates is connected inside the fixed frame. The moving component includes two screws rotating inside the fixed frame, with two connecting pipes threaded to the outer surfaces of the two screws. The conveyor belt moves the box, and the moving component adjusts the position of the pressing plates, facilitating the flattening of boxes of different sizes. A correction component ensures the box is centered. After the box reaches the bottom of the printing press, printing begins. The conveyor belt then drives a rotating component to rotate, which in turn drives a blowing component to blow air onto the box, facilitating rapid cooling and forming of the pattern.

[0004] However, the aforementioned flattening mechanism only uses two pressure plates to flatten the paper boxes on the conveyor belt vertically, without a rolling and flattening effect on the paper boxes, which results in wrinkles on the surface of the paper boxes that reduce the printing effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an auxiliary flattening mechanism for cold foil stamping transfer of pharmaceutical packaging boxes, which can roll and flatten paper boxes, eliminate wrinkles on the surface of paper boxes, and improve printing effect.

[0006] This utility model discloses an auxiliary flattening mechanism for cold foil stamping transfer printing on pharmaceutical packaging boxes. It includes a frame and a conveyor belt, with the conveyor belt mounted on the frame. It also includes a gantry, a push cylinder, a cross plate, support rods, pressure rollers, and an elastic component. The gantry is mounted on the frame, and the fixed end of the push cylinder is mounted on the gantry. The lower end of the piston rod of the push cylinder is mounted on the cross plate. Two sets of support rods are provided, with their upper ends rotatably connected to both ends of the cross plate. Two pressure rollers are provided, each rotatably mounted on the lower end of one of the two sets of support rods. The two pressure rollers are arranged opposite each other, and the two sets of support rods are arranged in an A-shape. Both ends of the elastic component are connected to the two sets of support rods. During operation, the conveyor belt pushes the cardboard box backward. During conveying, when the cardboard box is conveyed to the bottom of the gantry, the conveyor belt pauses, the piston rod of the push cylinder extends downward, pushing the horizontal plate down, so that the horizontal plate presses the two pressure rollers tightly against the middle of the cardboard box through two sets of support rods. The piston rod of the push cylinder continues to extend downward, causing the horizontal plate to continue to descend, thereby causing the two sets of support rods to open to both sides, driving the two pressure rollers to roll and flatten the cardboard box from the middle to both sides, eliminating wrinkles on the surface of the cardboard box. The elastic force of the elastic component causes the two sets of support rods to move inward, so that the two pressure rollers maintain the rolling force on the cardboard box. Due to the relative movement of the two pressure rollers, the cardboard box is subjected to balanced forces, making the cardboard box more stable, which is conducive to improving the printing quality of the cardboard box.

[0007] Preferably, the elastic component is a shock-absorbing spring assembly.

[0008] Preferably, it also includes a vertical rod, a second elastic component, and a pressure plate. The upper end of the vertical rod is slidably inserted into the horizontal plate. The two ends of the second elastic component are respectively connected to the horizontal plate and the vertical rod. The pressure plate is installed at the lower end of the vertical rod and is located between the two pressure rollers. When the two pressure rollers roll the paper box, the pressure plate presses against the middle of the paper box. When the horizontal plate descends, the second elastic component is stretched and stores force, thereby maintaining the pressure of the pressure plate on the paper box and further improving the stability of the paper box when the two pressure rollers roll and push the paper box.

[0009] Preferably, it also includes two guide plates, which are installed opposite each other on the conveyor belt. The two guide plates are located in front of the gantry and are used to organize the paper boxes. The conveyor belt transports the paper boxes backward, and the two guide plates guide and organize the paper boxes so that the paper boxes are aligned with the two pressure rollers and the paper boxes are neatly arranged.

[0010] Preferably, the assembly also includes two upright plates, a horizontal rail, two slides, two mounting rods, a double-threaded screw, a motor, and two slide blocks. The two upright plates are mounted opposite each other on the frame. The two ends of the horizontal rail are connected to the two upright plates respectively. The two slides are slidably mounted on the horizontal rail. The lower ends of the two mounting rods are connected to the two guide plates respectively, and the upper ends of the two mounting rods are connected to the two slides respectively. The double-threaded screw is rotatably mounted on the two upright plates. The motor is mounted on the upright plates, and the output shaft of the motor is driven by the double-threaded screw. The two slide blocks are driven by the double-threaded screw through screw nuts. The two slide blocks are symmetrically arranged and are connected to the two slides respectively. The motor drives the double-threaded screw to rotate, and the positive and negative threads of the double-threaded screw drive the two slide blocks to move relative to each other, so that the two slide blocks drive the two slides to move closer or further apart. This allows the two slides to drive the two guide plates to move closer or further apart through the two mounting rods, adapting to different sizes and specifications of cardboard boxes and providing good versatility.

[0011] Preferably, the device also includes two limit blocks, two contact switches, and two electromagnetic blocks. The two limit blocks are mounted on the horizontal rail, and the two contact switches are respectively mounted on the two limit blocks, each facing one of the two slides. The two electromagnetic blocks are respectively mounted on the two slide bases and are used to magnetically connect the two slides. The two slide bases are magnetically connected to the two slides via the two electromagnetic blocks, allowing the two slide bases to drive the two slides to move along the horizontal rail. The positions of the two limit blocks are adjusted according to the edge position of the cardboard box. The two contact switches are electrically connected to the controllers of the two electromagnetic blocks. When a slide contacts a contact switch, the contact switch sends an electrical signal to the controller of the corresponding electromagnetic block, causing the corresponding electromagnetic block to be de-energized and disengaged from the slide. At this time, the slide base will not drive the slide to move, while the slide base on the other side can drive the slide on the other side to continue moving, adapting to asymmetrical cardboard box placement and providing good versatility.

[0012] Preferably, it also includes two locking blocks and two bolts. The two locking blocks are respectively installed on the upper ends of the two mounting rods. Each of the two slides is provided with a locking groove. The two locking blocks are respectively locked into the locking grooves of the two slides. The two bolts are respectively rotated and screwed onto the two slides and lock the two locking blocks. The locking blocks and bolts facilitate the installation and disassembly of the two mounting rods and the two slides.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the conveyor belt transports the cardboard box backward. When the cardboard box is transported to the bottom of the gantry, the conveyor belt stops, the piston rod of the push cylinder extends downward, and pushes the horizontal plate down, so that the horizontal plate presses the two pressure rollers tightly against the middle of the cardboard box through the two sets of support rods. The piston rod of the push cylinder continues to extend downward, so that the horizontal plate continues to descend, thereby opening the two sets of support rods to both sides, driving the two pressure rollers to roll and flatten from the middle of the cardboard box to both sides, eliminating wrinkles on the surface of the cardboard box. The elastic force of the elastic component causes the two sets of support rods to move inward, so that the two pressure rollers maintain the rolling force on the cardboard box. Due to the relative movement of the two pressure rollers, the cardboard box is subjected to balanced force, making the cardboard box more stable, which is conducive to improving the printing quality of the cardboard box.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Example 1

[0023] like Figures 1 to 4 As shown, the auxiliary flattening mechanism for cold foil stamping transfer on pharmaceutical packaging boxes includes a frame 1 and a conveyor belt 2, with the conveyor belt 2 mounted on the frame 1. It also includes a gantry 3, a push cylinder 4, a horizontal plate 5, support rods 6, pressure rollers 7, and elastic components 8. The gantry 3 is mounted on the frame 1, the fixed end of the push cylinder 4 is mounted on the gantry 3, and the lower end of the piston rod of the push cylinder 4 is mounted on the horizontal plate 5. Two sets of support rods 6 are provided, with the upper ends of the two sets of support rods 6 rotatably connected to both ends of the horizontal plate 5. Two pressure rollers 7 are provided. The two pressure rollers 7 are rotatably installed at the lower ends of the two sets of support rods 6, and the two sets of support rods 6 are arranged in an A-shape. The two ends of the elastic component 8 are respectively connected to the two sets of support rods 6. The elastic component 8 is a shock-absorbing spring assembly. It also includes a vertical rod 9, an elastic component 10, and a pressure plate 11. The upper end of the vertical rod 9 is slidably inserted into the horizontal plate 5. The two ends of the elastic component 10 are respectively connected to the horizontal plate 5 and the vertical rod 9. The pressure plate 11 is installed at the lower end of the vertical rod 9 and is located between the two pressure rollers 7.

[0024] During operation, conveyor belt 2 transports the cardboard box backward. When the cardboard box reaches below the gantry 3, conveyor belt 2 pauses, and the piston rod of push cylinder 4 extends downward, pushing the horizontal plate 5 down. This causes the horizontal plate 5 to press the two pressure rollers 7 against the center of the cardboard box via two sets of support rods 6. The piston rod of push cylinder 4 continues to extend downward, causing the horizontal plate 5 to continue to descend. This causes the two sets of support rods 6 to open to both sides, driving the two pressure rollers 7 to roll and flatten the cardboard box from the center to both sides, eliminating wrinkles on the surface of the cardboard box. Elastic component 8... The elastic force causes the two sets of support rods 6 to move inward, thereby allowing the two pressure rollers 7 to maintain the rolling force on the paper box. Due to the relative movement of the two pressure rollers 7, the paper box is subjected to balanced forces, making the paper box more stable. When the two pressure rollers 7 roll the paper box, the pressure plate 11 presses against the middle of the paper box. When the horizontal plate 5 descends, the elastic component 10 is stretched and stores force, thereby allowing the pressure plate 11 to maintain pressure on the paper box, further improving the stability of the paper box when the two pressure rollers 7 roll and push the paper box, which is beneficial to improving the printing quality of the paper box.

[0025] Example 2

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, based on Embodiment 1, it also includes two guide plates 12, which are mounted opposite each other on the conveyor belt 2. The two guide plates 12 are located in front of the gantry 3 and are used to organize the cardboard boxes. It also includes two upright plates 13, a horizontal rail 14, two slides 15, two mounting rods 16, a double-threaded screw 17, a motor 18, and two slide blocks 19. The two upright plates 13 are mounted opposite each other on the frame 1. The two ends of the horizontal rail 14 are respectively connected to the two upright plates 13. The two slides 15 are slidably mounted on the horizontal rail 14. The lower ends of the two mounting rods 16 are respectively connected to the two guide plates 12, and the upper ends of the two mounting rods 16 are respectively connected to the two slides 15. A bidirectional threaded screw 17 is rotatably mounted on two vertical plates 13. A motor 18 is mounted on the vertical plate 13, and the output shaft of the motor 18 is connected to the bidirectional threaded screw 17 via a transmission connection. Two slide blocks 19 are connected to the bidirectional threaded screw 17 via screw nuts. The two slide blocks 19 are symmetrically arranged and are connected to two slide tables 15 respectively. The system also includes two locking blocks 23 and two bolts 24. The two locking blocks 23 are respectively mounted on the upper ends of two mounting rods 16. Each slide table 15 has a locking groove, and the two locking blocks 23 are respectively locked into the locking grooves of the two slide tables 15. The two bolts 24 are respectively rotatably screwed onto the two slide tables 15 and lock the two locking blocks 23.

[0027] The installation and removal of the two mounting rods 16 and the two slides 15 are facilitated by setting the locking block 23 and the bolt 24. The motor 18 drives the bidirectional threaded screw 17 to rotate. The forward and reverse threads of the bidirectional threaded screw 17 drive the two slides 19 to move relative to each other, so that the two slides 19 drive the two slides 15 to move closer or further away from each other. The two slides 15 drive the two guide plates 12 to move closer or further away from each other through the two mounting rods 16, which can accommodate paper boxes of different sizes and specifications. The conveyor belt 2 transports the paper boxes backward. The two guide plates 12 guide and sort the paper boxes, aligning the paper boxes with the two pressure rollers 7 and arranging the paper boxes neatly.

[0028] Example 3

[0029] like Figure 5 and Figure 6 As shown, based on Embodiment 2, it also includes two limiting blocks 20, two contact switches 21 and two electromagnetic suction blocks 22. The two limiting blocks 20 are installed on the horizontal rail 14, the two contact switches 21 are respectively installed on the two limiting blocks 20, and the two contact switches 21 are respectively facing the two slides 15. The two electromagnetic suction blocks 22 are respectively installed on the two slides 19, and the two electromagnetic suction blocks 22 are used to attract and connect the two slides 15.

[0030] Two slide blocks 19 are magnetically connected to two slide tables 15 via two electromagnetic suction blocks 22, allowing the two slide blocks 19 to drive the two slide tables 15 to move along the horizontal rail 14. The positions of the two limit blocks 20 are adjusted according to the edge position of the cardboard box. Two contact switches 21 are electrically connected to the controllers of the two electromagnetic suction blocks 22. When the slide table 15 contacts the contact switch 21, the contact switch 21 sends an electrical signal to the controller of the corresponding electromagnetic suction block 22, causing the corresponding electromagnetic suction block 22 to be de-energized and disengaged from the slide table 15. At this time, the slide block 19 will not drive the slide table 15 to move, while the slide block 19 on the other side can drive the slide table 15 on the other side to continue moving. This adapts to the situation of asymmetrical cardboard box placement and has good versatility.

[0031] like Figures 1 to 6 As shown, the auxiliary pressing mechanism for cold foil stamping transfer of pharmaceutical packaging boxes of this utility model, during operation, firstly, the conveyor belt 2 transports the cardboard box backward, and two guide plates 12 guide and arrange the cardboard box, aligning it with the two pressure rollers 7 and ensuring the cardboard box is neatly arranged. Then, when the cardboard box is transported to the bottom of the gantry 3, the conveyor belt 2 pauses, and the piston rod of the push cylinder 4 extends downward, pushing the horizontal plate 5 down. This causes the horizontal plate 5 to press the two pressure rollers 7 tightly against the middle of the cardboard box through two sets of support rods 6. The piston rod of the push cylinder 4 continues to extend downward, causing the horizontal plate 5 to continue to descend, thereby... The two sets of support rods 6 are opened to the sides, driving the two pressure rollers 7 to roll and flatten the paper box from the middle to the sides, eliminating wrinkles on the surface of the paper box. Then, the elastic force of the elastic component 8 causes the two sets of support rods 6 to move inward, so that the two pressure rollers 7 maintain the rolling force on the paper box. Finally, when the two pressure rollers 7 roll the paper box, the pressure plate 11 presses firmly on the middle of the paper box. When the horizontal plate 5 descends, the elastic component 10 is stretched and stores force, so that the pressure plate 11 maintains the pressure on the paper box, so that the paper box maintains stability when the two pressure rollers 7 roll and push the paper box, thereby improving the subsequent printing quality of the paper box.

[0032] The main functions achieved by this utility model are:

[0033] 1. It can roll and flatten paper boxes, eliminating wrinkles on the surface of the paper boxes and improving printing results;

[0034] 2. When the rollers push the paper box, the pressure plate 11 flattens and tightens the paper box, improving its stability;

[0035] 3. It can organize cardboard boxes of different sizes and specifications, so that the cardboard boxes are arranged neatly.

[0036] The auxiliary pressing mechanism for cold foil stamping of pharmaceutical packaging boxes of this utility model has common mechanical installation, connection and setting methods. As long as it can achieve the beneficial effect, it can be implemented. The frame 1, conveyor belt 2, push cylinder 4, pressure roller 7, elastic component 8, vertical rod 9, elastic component 2 10, pressure plate 11, guide plate 12, horizontal rail 14, slide table 15, mounting rod 16, bidirectional threaded screw 17, motor 18, slide base 19, limit block 20, contact switch 21, electromagnetic suction block 22, and bolt 24 of the auxiliary pressing mechanism for cold foil stamping of pharmaceutical packaging boxes of this utility model are purchased from the market.
