Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment, and in particular to a cold foil transfer printing device for pharmaceutical packaging. Background Technology

[0002] Cold foil stamping uses UV light to irradiate UV adhesive, causing the object to be transferred to cure on the transfer carrier, thus achieving the transfer. Cold foil stamping uses UV adhesive to cure the object, can be performed at room temperature, and does not require heating, making it more convenient and safer.

[0003] Chinese utility model patent with publication number CN219338921U discloses a top-mounting device and its cold foil transfer equipment. The transfer equipment includes a mounting frame, a top-mounting drive, and a top-mounting component. The top-mounting drive is mounted on the mounting frame, and the top-mounting component is positioned above the mounting frame and connected to the top-mounting component. The top-mounting drive drives the top-mounting component to rise or fall. The top-mounting component is used to rise from below the conveyor belt frame of the cold foil transfer equipment and lift the cold foil transfer carrier during UV irradiation. By setting up the top-mounting drive and the top-mounting component, under the drive of the top-mounting drive, the top-mounting component can rise from below the conveyor belt frame of the cold foil transfer equipment and lift the cold foil transfer carrier, giving the transfer carrier further upward pressure, making it closely adhere to the transfer object, and ensuring full adhesion between the transfer object and the transfer carrier, thereby improving the cold foil curing effect.

[0004] However, the top pressure roller of the above-mentioned transfer device is fixed and cannot make timely adaptive adjustments when the cold foil is subjected to large tension, which will cause the cold foil to deform and the transfer quality to decline. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cold foil transfer device for pharmaceutical packaging that improves the transfer quality by setting an adaptively movable roller that can lift and lower, thus avoiding excessive stretching and deformation of the transfer film.

[0006] This utility model discloses a cold foil stamping transfer device for pharmaceutical packaging, comprising a base plate and a fixed roller, the fixed roller being rotatably mounted on the left end of the base plate; it also includes a slide table, a movable roller frame, two vertical sliding grooves, a roller shaft, a movable roller, and a reciprocating mechanism. The slide table is slidably mounted on a slide rail on the base plate via a slider. The movable roller frame is vertically mounted on the slide table, with vertical sliding grooves at both ends. The roller shaft is slidably mounted in the two vertical sliding grooves at both ends, and the movable roller is rotatably mounted on the roller shaft. The reciprocating mechanism is mounted on the base plate and drives the slide table to rotate on the base plate. The plate moves back and forth; during operation, the end of the transfer film passes over the top of the fixed roller and then through the bottom of the movable roller before being conveyed backward. The reciprocating mechanism drives the slide to move back and forth on the base plate. The slide drives the movable roller frame, roller shaft, and movable roller to move back and forth, causing the movable roller to pull the transfer film back and forth. When the transfer film is subjected to a large tension, the transfer film will tighten and push the movable roller upward. The movable roller drives the roller shaft to slide up and down along the two vertical grooves, avoiding excessive stretching and deformation of the transfer film and improving the transfer quality.

[0007] Preferably, it also includes two counterweights, which are installed at both ends of the roller shaft; the two counterweights balance the roller shaft and the movable roller, and by adjusting the specifications of the two counterweights, different tension effects can be achieved on the transfer film.

[0008] Preferably, it also includes two pins, and each of the ends of the two rollers is provided with a insertion hole. The two counterweights are detachably installed on both ends of the rollers, and the two pins are respectively inserted into the two insertion holes of the rollers. After replacing the two counterweights with different specifications, the two pins are inserted into the two insertion holes of the rollers to block and limit the two counterweights, thereby improving the stability of the two counterweights.

[0009] Preferably, it also includes a push cylinder, two slide rods, and two sliding sleeves. The fixed end of the push cylinder is mounted on the slide table, the piston rod of the push cylinder is connected to the moving roller frame, the upper ends of the two slide rods are connected to the lower end face of the moving roller frame, the two sliding sleeves are mounted on the slide table, and the lower parts of the two slide rods are slidably inserted into the two sliding sleeves. The piston rod of the push cylinder extends and retracts to push the moving roller frame up and down, and the two slide rods and two sliding sleeves cooperate to slide and limit the moving roller frame, thereby improving stability.

[0010] Preferably, the reciprocating mechanism includes two lead screws, two double-sided bevel gears, a drive shaft, bevel gear one, bevel gear two, a drive motor, two limit blocks, and two locking bolts. The two lead screws are rotatably mounted on the base plate and are connected to the slide table via lead screw nuts. The two double-sided bevel gears are concentrically mounted on the ends of the two lead screws, and multiple bevel teeth are provided on the front and rear sides of the two double-sided bevel gears. The drive shaft is rotatably and axially slidingly mounted on the base plate, located between the two lead screws. Bevel gear one and bevel teeth are concentrically mounted on the end of the drive shaft. Wheel 2, bevel gear 1 and bevel gear 2 are located on the front and rear sides of the two double-sided bevel gears respectively. Bevel gear 1 and bevel gear 2 face the front and rear bevel teeth of the two double-sided bevel gears respectively. The drive motor is mounted on the base plate. The output shaft of the drive motor is concentrically mounted with the driving bevel gear, which is located between the two double-sided bevel gears. The driving bevel gear meshes with either bevel gear 1 or bevel gear 2. Two limit blocks are slidably mounted on the drive shaft. The two limit blocks are located on both sides of the slide table. Two locking bolts are rotatably screwed onto the two limit blocks respectively. The inner ends contact the drive shaft respectively; adjust the position of the drive shaft so that bevel gear one meshes with multiple bevel teeth on the rear side of the two double-sided bevel gears and the driving bevel gear of the drive motor. The output shaft of the drive motor drives the driving bevel gear to rotate, and the driving bevel gear meshes with and drives bevel gear one to rotate. Bevel gear one simultaneously meshes with the two double-sided bevel gears and rotates in the forward direction, so that the two double-sided bevel gears drive the two lead screws to rotate synchronously, thereby causing the two lead screws to drive the slide table to move forward. When the slide table moves to the limit block located on the front side and impacts and pushes the limit block forward, the slide table drives the drive shaft to move forward. The movement causes the drive shaft to disengage bevel gear one from the two double-sided bevel gears and engage bevel gear two with the multiple bevel teeth on the rear side of the two double-sided bevel gears and the drive motor's active bevel gear. At this time, the drive motor's active bevel gear engages and drives bevel gear two to reverse. Bevel gear two engages with the two double-sided bevel gears and the two lead screws to reverse, causing the two lead screws to drive the slide table to move backward. Repeating the above actions causes the slide table to move back and forth. By adjusting the position of the two limit blocks and tightening them with two locking bolts, the travel of the slide table can be limited, which is practical.

[0011] Preferably, it also includes two buffer pads, which are respectively installed on the end faces of the two limit blocks facing the slide table; by installing the two buffer pads, the limit blocks and the slide table are buffered to avoid collision damage.

[0012] Preferably, it also includes connecting columns, with connecting columns installed on the ends of both lead screws and the end of the drive shaft; by installing multiple connecting columns, the operator can manually drive the lead screws and drive shaft to rotate, improving practicality.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the end of the transfer film passes over the top of the fixed roller and then through the bottom of the movable roller before being conveyed backward. The reciprocating mechanism drives the slide table to move back and forth on the base plate. The slide table drives the movable roller frame, roller shaft and movable roller to move back and forth, so that the movable roller pulls the transfer film back and forth. When the transfer film is subjected to a large tension, the transfer film will be taut and thus push the movable roller upward. The movable roller drives the roller shaft to slide up and down along the two vertical grooves, which avoids the transfer film being excessively stretched and deformed, and improves the transfer quality.

[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. Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the cold foil stamping transfer device for pharmaceutical packaging includes a base plate 1 and a fixed roller 2, which is rotatably mounted on the left end of the base plate 1. It also includes a slide table 3, a movable roller frame 4, two vertical grooves 5, a roller shaft 6, a movable roller 7, and a reciprocating mechanism. The slide table 3 is slidably mounted on a slide rail on the base plate 1 via a slider. The movable roller frame 4 is vertically mounted on the slide table 3, with vertical grooves 5 at both ends. The roller shaft 6 is slidably mounted in the two vertical grooves 5 at both ends. The movable roller 7 rotates... The moving roller frame 4 is mounted on the roller shaft 6, and the reciprocating mechanism is mounted on the base plate 1. The reciprocating mechanism drives the slide table 3 to move back and forth on the base plate 1. It also includes a push cylinder 10, two slide rods 11 and two slide sleeves 12. The fixed end of the push cylinder 10 is mounted on the slide table 3. The piston rod of the push cylinder 10 is connected to the moving roller frame 4. The upper ends of the two slide rods 11 are connected to the lower end face of the moving roller frame 4. The two slide sleeves 12 are mounted on the slide table 3. The lower parts of the two slide rods 11 are slidably inserted into the two slide sleeves 12.

[0023] The piston rod of the push cylinder 10 extends and retracts to push the moving roller frame 4 up and down. The two slide rods 11 and the two slide sleeves 12 cooperate to slide and limit the moving roller frame 4, adjusting the initial height of the movable roller 7.

[0024] During operation, the end of the transfer film passes over the top of the fixed roller 2 and then through the bottom of the movable roller 7 before being conveyed backward. The reciprocating mechanism drives the slide table 3 to move back and forth on the base plate 1. The slide table 3 drives the movable roller frame 4, roller shaft 6 and movable roller 7 to move back and forth, so that the movable roller 7 reciprocates and pulls the transfer film. When the transfer film is subjected to a large tension, the transfer film will tighten and thus push the movable roller 7 upward. The movable roller 7 drives the roller shaft 6 to slide up and down along the two vertical slide grooves 5, which avoids the transfer film being excessively stretched and deformed, and improves the transfer quality.

[0025] It also includes two counterweights 8, which are installed on both ends of the roller shaft 6; it also includes two pins 9, each with a insertion hole on its end. The two counterweights 8 are detachably installed on both ends of the roller shaft 6, and the two pins 9 are inserted into the two insertion holes of the roller shaft 6 respectively.

[0026] After replacing the two counterweights 8 with two different specifications, insert the two pins 9 into the two holes of the roller 6 to block and limit the two counterweights 8, thereby improving the stability of the two counterweights 8. The two counterweights 8 provide weight to the roller 6 and the movable roller 7. By adjusting the specifications of the two counterweights 8, different tension effects can be achieved on the transfer film. Example 2

[0027] like Figure 4 and Figure 5As shown, based on Embodiment 1, the reciprocating mechanism includes two lead screws 15, two double-sided bevel gears 16, a drive shaft 17, a first bevel gear 18, a second bevel gear 19, a drive motor 20, two limit blocks 21, and two locking bolts 22. The two lead screws 15 are rotatably mounted on the base plate 1, and are connected to the slide table 3 via lead screw nuts. The two double-sided bevel gears 16 are concentrically mounted on the ends of the two lead screws 15, and multiple bevel teeth are provided on the front and rear sides of each double-sided bevel gear 16. The drive shaft 17 is rotatably and axially slidingly mounted on the base plate 1, located between the two lead screws 15. A first bevel gear 18 and a second bevel gear 19 are concentrically mounted on the end of the drive shaft 17, located on the front and rear sides of the two double-sided bevel gears 16, respectively. Bevel gear 18 and bevel gear 19 face the front and rear bevel teeth of the two double-sided bevel gears 16, respectively. The drive motor 20 is mounted on the base plate 1. The output shaft of the drive motor 20 is concentrically mounted with the driving bevel gear, which is located between the two double-sided bevel gears 16. The driving bevel gear meshes with bevel gear 18 or bevel gear 19. Two limit blocks 21 are slidably mounted on the drive shaft 17. The two limit blocks 21 are located on both sides of the slide table 3. Two locking bolts 22 are rotatably screwed onto the two limit blocks 21, and the inner ends of the two locking bolts 22 are in contact with the drive shaft 17. The system also includes two buffer pads 23, which are mounted on the end faces of the two limit blocks 21 facing the slide table 3. The system also includes connecting columns 24, which are mounted on the ends of the two lead screws 15 and the end of the drive shaft 17.

[0028] Adjusting the position of drive shaft 17 causes bevel gear 18 to mesh with multiple bevel teeth on the rear side of two double-sided bevel gears 16 and the driving bevel gear of drive motor 20. The output shaft of drive motor 20 drives the driving bevel gear to rotate, and the driving bevel gear meshes with and drives bevel gear 18 to rotate. Bevel gear 18 simultaneously meshes with the two double-sided bevel gears 16 to rotate in the forward direction, causing the two double-sided bevel gears 16 to drive the two lead screws 15 to rotate synchronously. This causes the two lead screws 15 to drive slide 3 to move forward. When slide 3 moves to the front limit block 21 and impacts and pushes the limit block 21 forward, two buffer pads 23 are installed to buffer the limit block 21 and slide 3 to avoid collision damage. Slide 3 drives drive shaft 17 to move forward, causing the drive shaft 17 to rotate. The drive shaft 17 drives the first bevel gear 18 to disengage from the two double-sided bevel gears 16 and causes the second bevel gear 19 to mesh with the multiple bevel teeth on the rear side of the two double-sided bevel gears 16 and the driving bevel gear of the drive motor 20. At this time, the driving bevel gear of the drive motor 20 meshes and drives the second bevel gear 19 to reverse. The second bevel gear 19 meshes with the two double-sided bevel gears 16 and the two lead screws 15 to reverse, causing the two lead screws 15 to drive the slide table 3 to move backward. The above actions are repeated to make the slide table 3 move back and forth. By adjusting the position of the two limit blocks 21 and tightening them with the two locking bolts 22, the travel of the slide table 3 is limited. By installing multiple connecting columns 24, the operator can manually drive the lead screws 15 and the drive shaft 17 to rotate.

[0029] like Figures 1 to 6 As shown, in operation, the cold foil transfer device for pharmaceutical packaging of this utility model first passes the end of the transfer film around the top of the fixed roller 2, then through the bottom of the movable roller 7, and is conveyed backward. After replacing the two counterweights 8 of the specified specifications, two pins 9 are inserted into the two holes of the roller shaft 6 to block and limit the two counterweights 8. Then, the piston rod of the push cylinder 10 extends and retracts to push the movable roller frame 4 up and down. The two sliding rods 11 and two sliding sleeves 12 cooperate to slide and limit the movable roller frame 4, adjusting the height of the movable roller 7. Then, by adjusting the two... The position of the limit block 21 is locked by tightening two locking bolts 22, which limits the travel of the slide table 3. The reciprocating mechanism drives the slide table 3 to move back and forth on the base plate 1. The slide table 3 drives the moving roller frame 4, roller shaft 6 and movable roller 7 to move back and forth, so that the movable roller 7 pulls the transfer film back and forth. Finally, when the transfer film is subjected to a large tension, the transfer film will be taut and thus push the movable roller 7 upward. The movable roller 7 drives the roller shaft 6 to slide up and down along the two vertical sliding grooves 5, so as to avoid the transfer film being excessively stretched and deformed.

[0030] The main functions achieved by this utility model are:

[0031] 1. By setting an adaptive movable roller 7, the transfer film is prevented from being excessively stretched and deformed, thus improving the transfer quality;

[0032] 2. The height of the movable roller 7 can be adjusted;
