Description

Technical Field

[0001] This invention relates to the field of printing auxiliary equipment technology, and more specifically to an automatic loading and unloading device for flexographic printing. Background Technology

[0002] Flexographic printing is a type of letterpress printing that uses an anilox roller to transfer ink. Before printing, the paper tube needs to be manually installed onto the winding roller, and then the winding roller and the paper tube are placed together on the printing press. After processing, when collecting the paper, the winding roller needs to be manually removed. Because the paper tube is large, it often requires the cooperation of many people to remove it, which slows down the efficiency of loading and unloading. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use automatic loading and unloading device for flexographic printing. This solves the problem of manual loading and unloading, thus eliminating the need for multiple people to cooperate in loading and unloading, and improving the efficiency of loading and unloading.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: it comprises a base, a support plate, support feet, and a placement plate. A support plate is provided on one side of the upper surface of the base, and a placement plate is suspended above the other side of the base. Support feet are fixed to the four corners of the lower surface of the placement plate, and the lower ends of the support feet are fixed to the upper surface of the base. It further comprises:

[0005] The feeding box is located on the upper side of the placement plate, and the lower side wall of the feeding box is provided with a discharge port, which is connected to the strip hole on the placement plate.

[0006] The feeding pipe is fixed on the lower surface of the placement plate. The feeding pipe has an open structure on the side adjacent to the support plate and the upper side. The feeding pipe is located below the discharge port.

[0007] The material feeding box is located on the front side of the support leg, and a groove is provided on the side wall of the material feeding box adjacent to the support plate.

[0008] A pad is provided on the front side of the base, and a feeding box is provided on the pad. The rear side of the upper surface of the pad is screwed to the front side of the upper surface of the base by a hinge.

[0009] The loading and unloading mechanism is mounted on a support plate and is configured in conjunction with the loading pipe and the unloading box.

[0010] The moving mechanism consists of two mechanisms, which are respectively installed in the embedded grooves on both sides of the lower side wall of the base. The base is composed of two connecting plates, and the moving mechanisms are respectively installed on the opposite side of the two connecting plates.

[0011] A connecting mechanism is provided in a mounting groove on the opposite sidewall of the connecting plates on both sides;

[0012] The above technical solution involves placing an empty winding roller in the feeding box, allowing it to fall into the feeding tube via the discharge port and the slot on the placement plate. The roller is then fed through the loading / unloading mechanism, positioning it on the printing press. The printed flexographic material is then wound onto the empty winding roller. After winding, the roller is moved to the unloading box by the loading / unloading mechanism for unloading. When not in use, the distance between the two connecting plates is reduced via the connecting mechanism to minimize space usage. Finally, the device is moved to its designated storage location via the moving mechanism for easy storage.

[0013] As a further improvement of the present invention, guide blocks are fixed on both the front and rear inner walls of the feeding box. The lower side of the guide block is fixed on the inner bottom wall of the feeding box. The two guide blocks are located on the front and rear sides of the discharge port, respectively. The upper side wall of the guide block is inclined upward on the side away from the discharge port.

[0014] The above technical solution guides the empty winding rollers, thereby preventing the two winding rollers from getting stuck on both sides of the discharge port and facilitating material unloading.

[0015] As a further improvement of the present invention, the loading and unloading mechanism includes:

[0016] A fixed screw tube is provided inside the feeding tube. A fixed screw rod is screwed into the inside of the fixed screw tube by a thread. One end of the fixed screw rod passes through the fixed screw tube and is exposed on the outside of the feeding tube.

[0017] The fixing block is screwed onto the outer end of the fixing screw via a bearing. The fixing block has limit rods fixed on both the front and rear sides of the side wall adjacent to the fixing screw. The other end of the limit rod is movably inserted into the annular wall of the fixing screw tube.

[0018] A rotating motor is embedded and fixed inside a fixed block, and the output shaft of the rotating motor is fixedly connected to one end of a fixed screw located inside the fixed block.

[0019] A pushing mechanism is provided on one side of the support plate and is connected to the fixed block;

[0020] The feeding plate is set in the groove, and the lower side of the feeding plate is embedded in one side wall of the feeding box. The front and rear sides of the feeding plate are slidably set in the front and rear side walls of the groove, respectively. The upper side of the side wall away from the inside of the feeding box is inclined to the inside of the feeding box.

[0021] The reset springs are multiple in number and are fixed at equal intervals on the lower side wall of the feed plate, and the reset springs are fixed on the inner bottom wall of one side wall of the feed box.

[0022] With the above technical solution, during movement, the rotary motor is started, driving the fixed screw to rotate. The fixed screw moves the fixed screw tube out of the feeding tube, at which point the empty winding roller falls into the feeding tube. Then, the rotary motor is started in reverse, driving the fixed screw to rotate in the opposite direction. The fixed screw moves the fixed screw tube into the feeding tube, thus inserting the fixed screw tube into the empty winding roller. The rotary motor is then started again, driving the winding roller outward through the fixed screw and fixed screw tube, placing the winding roller on the printing press for printing. After printing, the pushing mechanism moves the fixed block, which in turn moves the fully wound winding roller to the unloading position via the fixed screw and fixed screw tube. The motor is turned on one side of the box, and then the rotation motor is started in reverse. The fixed screw drives the fixed screw tube to move, so that the winding roller abuts against the inclined surface of the feeding plate and continues to move to one side of the feeding box. The feeding plate moves to the side wall of the feeding box until the winding roller is suspended inside the feeding box. At this time, the return spring drives the feeding plate to move upward until it abuts against the fixed screw tube. Then the rotation motor is turned in reverse, so that the fixed screw tube moves outward. At this time, the winding roller abuts against the feeding plate. After the fixed screw tube moves out of the feeding box, the winding roller falls into the feeding box, completing the feeding operation. Then the pushing mechanism drives the fixed screw and fixed screw tube to one side of the feeding tube for feeding again.

[0023] As a further improvement of the present invention, the driving mechanism includes:

[0024] A movable plate abuts against one side wall of a support plate. The movable plate is connected to a fixed block. A sliding block is fixed on one side wall of the movable plate adjacent to the support plate. The sliding block is slidably disposed in a groove on the side wall of the support plate.

[0025] A push screw is embedded in a support plate. The rear end of the push screw is screwed to the rear inner wall of the support plate through a bearing. The front end of the push screw passes through a sliding block through a thread and is screwed to the front side wall of the support plate through a bearing.

[0026] A drive motor is fixed on the rear side wall of the support plate. The drive motor is connected to an external power source. The output shaft of the drive motor is inserted into the support plate and fixedly connected to the rear end of the drive screw.

[0027] The above technical solution involves starting a drive motor, which in turn drives a lead screw to rotate. As the lead screw rotates, it causes a sliding block to move back and forth. The sliding block then moves a moving plate, which in turn moves a fixed block.

[0028] As a further improvement of the present invention, two electric push rods are fixed to the front end of one side wall of the movable plate, and the output end of the electric push rods is fixedly connected to the fixed block;

[0029] With the above technical solution, when the fixed screw tube is moved into the feeding tube and the unloading box, the fixed block is pushed by the electric push rod, which makes it easier to insert the fixed screw tube into the feeding tube and the unloading box.

[0030] As a further improvement of the present invention, the moving mechanism includes:

[0031] A mobile motor is fixed to the front side wall of the base. The mobile motor has its own power supply, and the output shaft of the mobile motor is inserted into the base.

[0032] A rotating shaft, the front end of which is fixed to the output shaft of a mobile motor, and the rear end of which is screwed to the inner rear wall of the base via a bearing;

[0033] The cam, wherein there are several cams, which are equidistantly nested and fixed on the rotating shaft, and the lower side of the cam abuts against the lifting plate, and the outer peripheral wall of the lifting plate abuts against the inner peripheral wall of the embedded groove on the lower side wall of the base;

[0034] The casters are multiple in number and are screwed onto the lower surface of the lifting plate in a matrix manner, with the casters located in embedded grooves.

[0035] Using the above technical solution, the moving motor is started, which drives the rotating shaft to rotate. The rotating shaft drives the cam to rotate until the cam's protrusion abuts against the upper surface of the lifting plate, thereby causing the lifting plate to move downward. The lifting plate drives the casters to move downward until the casters move to the outside of the base, and the casters drive the device to move.

[0036] As a further improvement of the present invention, several guide rods are equidistantly inserted on the lifting plate. The upper end of the guide rod is fixed to the inner top wall of the embedding groove, and the lower end of the guide rod is fixedly connected to the inner wall of the embedding groove through a support plate.

[0037] The above technical solution uses guide rods to support and guide the lifting plate, preventing it from tilting.

[0038] As a further improvement of the present invention, the connecting mechanism includes:

[0039] The movable blocks are four in number, and they are slidably arranged in pairs on the inner wall of one side of the mounting groove.

[0040] A connecting screw is embedded in a connecting plate on one side. The threads at both ends of the connecting screw are arranged in opposite directions. The two ends of the connecting screw are respectively screwed to the front and rear inner walls of the connecting plate through bearings. The threads at both ends of the connecting screw are respectively screwed to two adjacent moving blocks.

[0041] A connecting motor is fixed on the front side wall of a connecting plate on one side. The connecting motor is connected to an external power source. The output shaft of the connecting motor is inserted into the connecting plate and is fixedly connected to the front end of a connecting screw.

[0042] The telescopic link has two sides respectively set in the mounting grooves on both sides, and the ends of the telescopic link on both sides are respectively screwed to the moving block through the hinge seat;

[0043] Using the above technical solution, the connecting motor is started, which drives the connecting screw to rotate. The connecting screw drives the moving blocks at both ends to move in opposite directions, thereby causing the telescopic connecting rod to extend and retract, which in turn causes the distance between the two connecting plates to change until the distance between the support plate and the feeding box reaches the required distance.

[0044] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0045] 1. It can automatically load and unload materials, thus achieving the desired loading and unloading effect without the need for multiple people to cooperate, thereby improving work efficiency;

[0046] 2. Movable mechanisms are provided on both sides inside the base, which can easily move the device after use, allowing it to be moved and stored without manual handling, thus improving portability.

[0047] 3. The base consists of two connecting plates connected by a connecting mechanism, which allows the distance between the support plate and the feeding box to be adjusted according to the width of the printing press. Attached Figure Description

[0087] In using this invention, an empty winding roller is placed in the feeding box 5. The winding roller falls into the feeding pipe 6 through the discharge port 5-1 and the strip groove on the placement plate 4, and is then fed by the loading and unloading mechanism 9, so that the empty winding roller is positioned on the printing machine, thereby winding the printed flexographic material onto the empty winding roller. After winding is completed, the loading and unloading mechanism 9 moves the winding roller to the unloading box 7 for unloading. When not in use, the connecting motor 11-3 is started, and the connecting motor 11-3 drives the connecting screw 11-2 to rotate. The connecting screw 11-2 drives the moving blocks 11-1 at both ends to move in opposite directions, thereby causing the telescopic connecting rod 11- 4. The telescopic effect occurs, which causes the distance between the two connecting plates 1-1 to change until the distance between the support plate 2 and the feeding box 5 reaches the required distance, thereby reducing the space occupied. The moving motor 10-1 is started, and the moving motor 10-1 drives the rotating shaft 10-2 to rotate. The rotating shaft 10-2 drives the cam 10-3 to rotate until the protrusion of the cam 10-3 abuts against the upper surface of the lifting plate 10-4, thereby causing the lifting plate 10-4 to move downward. The lifting plate 10-4 drives the caster 10-5 to move downward until the caster 10-5 moves to the outside of the base 1. The caster 10-5 drives the device to move, making it easy to store.

[0088] During movement, start the rotating motor 9-5. The rotating motor 9-5 drives the fixed screw 9-2 to rotate, and the fixed screw 9-2 drives the fixed screw tube 9-1 to move out of the feeding tube 6. At this time, the empty winding roller falls into the feeding tube 6. Then start the rotating motor 9-5 in the reverse direction. The rotating motor 9-5 drives the fixed screw 9-2 to rotate in the reverse direction. The fixed screw 9-2 drives the fixed screw tube 9-1 to move into the feeding tube 6, so that the fixed screw tube 9-1 is inserted into the empty winding roller. Then start the rotating motor 9-5 again. Machine 9-5, rotating motor 9-5 drives the winding roller outward through fixed screw 9-2 and fixed screw tube 9-1, so that the winding roller is positioned on the printing press for printing. After printing is completed, drive motor 9-6-4 is started, which drives drive screw 9-6-3 to rotate. When drive screw 9-6-3 rotates, it drives sliding block 9-6-2 to move back and forth. Sliding block 9-6-2 drives moving plate 9-6-1 to move. Moving plate 9-6-1 drives fixed screw 9-6-2 to move. Block 9-3 moves, and the fixed block 9-3 drives the fully wound winding roller to move to one side of the unloading box 7 via the fixed screw 9-2 and the fixed screw tube 9-1. Then, the rotating motor 9-5 is started in reverse, and the fixed screw 9-2 drives the fixed screw tube 9-1 to move, so that the winding roller abuts against the inclined surface of the unloading plate 9-7 and continues to move to one side inside the unloading box 7, so that the unloading plate 9-7 moves downward to the side wall of the unloading box 7 until the winding roller is suspended inside the unloading box 7. At this time, the return spring 9-8 drives the feed plate 9-7 to move upward until it abuts against the fixed screw tube 9-1. Then, the rotating motor 9-5 rotates in the opposite direction, causing the fixed screw tube 9-1 to move outward. At this time, the winding roller abuts against the feed plate 9-7. After the fixed screw tube 9-1 moves out of the feed box 7, the winding roller falls into the feed box 7, completing the feeding operation. Then, the pushing mechanism 9-6 drives the fixed screw 9-2 and the fixed screw tube 9-1 to move to one side of the feed tube for feeding again.
