Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a printing device with an auxiliary positioning function, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A printing device with an auxiliary positioning function includes a support frame, a transportation device is arranged on the inner wall of the support frame, a motor is fixedly installed on one side of the support frame away from the transportation device, the transportation device is fixedly installed on the output end of the motor, a processing frame is fixedly installed on the top of the support frame, an ink storage tank is fixedly installed on the top of the processing frame, an ink outlet is fixedly installed on the top inner wall of the processing frame, and a clamping device is also provided on the top of the support frame; Among them, the clamping device includes a detector, an electric push rod, a pushing plate, a sliding plate, a rotating plate, an elastic telescopic rod, a pushing board, a rotating board, a clamping board and a push rod. The detector is fixedly installed at the top of the inner wall of the processing frame. The electric push rod is fixedly installed at the top of the inner wall of the processing frame. The pushing plate is fixedly installed at the output end of the electric push rod. The sliding plate is slidably installed on the inner wall of the processing frame. The elastic telescopic rod is fixedly installed on the inner wall of the processing frame. The pushing board is fixedly installed at the movable end of the elastic telescopic rod. The clamping board is fixedly installed on the side of the pushing board away from the elastic telescopic rod.

One end of the push rod is fixedly installed at the top of the clamping board, and the other end of the push rod is rotatably installed at the side of the rotating board close to the clamping board. When the pushing plate moves downward, it will push the sliding plate to move. The movement of the sliding plate will push the rotating plate to move. The movement of the rotating plate will push the pushing board to move towards the position of the plate, ensuring that the plate will not move randomly during inkjet printing on the plate, and avoiding deviation of the printed position caused by the movement of the plate.

[0007] According to the above technical solution, a first spring is provided between the sliding plate and the processing frame. The first spring is provided to drive the sliding plate back to its original position. A first torsion spring is provided between the rotating board and the pushing board. The first torsion spring is provided to drive the rotating board back to its original position. A second spring is provided between the pushing board and the clamping board. The second spring is provided to push the pushing board back to its original position. The control end of the detector is electrically connected to the electric push rod.

[0008] According to the above technical solution, a positioning device and a cleaning device are further provided on the top of the support frame. The positioning device includes a first hydraulic cylinder, a first hydraulic rod, a second hydraulic cylinder, a second hydraulic rod and a baffle. The first hydraulic cylinder is fixedly installed on the inner wall of the processing frame. One end of the first hydraulic rod is slidably installed inside the first hydraulic cylinder.

The second hydraulic cylinder is fixedly installed on the top of the support frame. The second hydraulic rod is slidably installed inside the second hydraulic cylinder. The baffle is fixedly installed at the movable end of the second hydraulic rod. When the baffle slides downward, it will block the transported plate, preventing the next plate from passing under the checker when the previous plate is being inkjet printed. Since the previous plate has not completed the printing operation, the detector may automatically pause or adjust the work through the conveyor belt control system, avoiding multiple plates entering the printing area simultaneously, resulting in equipment jamming or uneven printing.

[0009] According to the above technical solution, the alignment device further includes a guide plate and a push rod. The guide plate is fixedly installed on the inner wall of the support frame. One end of the push rod is rotatably installed on one side of the baffle close to the guide plate, and the other end of the push rod is rotatably installed on the top of the guide plate. When the baffle moves downward, it will drive the push rod to move. When the push rod moves, it will push the guide plate to move towards the direction close to the plate member, so that the plate member can be in the position between the clamping plates during transportation, which is convenient for clamping the plate member.

[0010] According to the above technical solution, the first hydraulic rod has the function of sealing the first hydraulic cylinder, the second hydraulic rod has the function of sealing the second hydraulic cylinder. The first hydraulic cylinder and the second hydraulic cylinder are connected by a hose. A third spring is provided between the guide plate and the support frame.

The inclined surface of the guide plate is provided to better guide the plate member.

[0011] According to the above technical solution, the cleaning device includes a rotating shaft, a large gear shaft, a small gear shaft, a rotating shaft, a cleaning roller and a fixing plate. The rotating shaft is fixedly installed at the output end of the transportation device. The large gear shaft is rotatably installed on one side of the support frame close to the rotating shaft. The fixing plate is rotatably installed on the top of the support frame. The small gear shaft penetrates through the fixing plate rotatably. The rotating shaft penetrates through the fixing plate rotatably. The cleaning roller is rotatably installed on one side of the rotating shaft close to the guide plate. When the small gear shaft rotates, it will drive the rotating shaft to rotate. When the rotating shaft rotates, it will drive the cleaning roller to rotate. When the cleaning roller rotates, it will clean the surface of the plate member. There may be dirt, dust, oil stains, fingerprints and other impurities on the surface of the plate member, which will affect the uniformity and adhesion of inkjet. Cleaning the surface can avoid these impurities from affecting the inkjet process.

[0012] According to the above technical solution, the cleaning device also includes a fixing plate, a rotating buckle and a T-shaped rod. The rotating buckle is rotatably installed on the top of the support frame. The T-shaped rod is fixedly installed on the top of the guide plate. A square groove is opened on one side of the fixing plate close to the rotating buckle. The shape of the square groove matches that of the rotating buckle. When the rotating buckle rotates, it will limit the fixing plate, so as to prevent the staff from rotating the fixing plate to replace the cleaning roller when cleaning the plate member, resulting in incomplete cleaning of the surface of the plate member.

[0013] According to the above technical solution, a second torsion spring is provided between the rotating buckle and the support frame. The second torsion spring is provided to drive the rotating buckle back to its original position. The T-shaped rod contacts the rotating buckle.

The rotating shaft and the small gear shaft are connected by a second belt in a transmission manner.

[0014] The present invention provides a printing device with an auxiliary positioning function. It has the following beneficial effects: (1) In this invention, when the pushing plate moves downward, it will push the sliding plate to move. The movement of the sliding plate will push the rotating plate to move, and the movement of the rotating plate will push the pushing plate towards the position of the plate member, ensuring that the plate member will not move randomly during inkjet printing on the plate member, and avoiding deviation in the printing position caused by the movement of the plate member. When the push rod moves, it will push the rotating plate to rotate, and the rotation of the rotating plate will block the surface of the plate member to a certain extent, preventing ink from splashing to other positions of the plate member when inkjet printing on the surface of the plate member, which may affect the printing accuracy of the plate member.

[0015] (2) In this invention, when the liquid in the second hydraulic cylinder decreases, it will pull the second hydraulic rod to slide into the second hydraulic cylinder. When the second hydraulic rod slides, it will pull the baffle to slide downward, and the downward sliding of the baffle will block the transported plate member. When inkjet printing is performed on the previous plate member, the next plate member passes under the bottom of the checker. Since the previous plate member has not completed the printing operation, the detector may automatically pause or adjust the work through the conveyor belt control system, avoiding multiple plate members entering the printing area simultaneously, which may cause the equipment to jam or the printing to be uneven. When the baffle moves downward, it will drive the push rod to move, and when the push rod moves, it will push the guide plate towards the direction close to the plate member, so that the plate member can be in the position between the clamping plates during transportation, facilitating the clamping of the plate member.

[0016] (3) In this invention, the rotation of the small gear shaft will drive the rotation of the rotating shaft, the rotation of the rotating shaft will drive the rotation of the cleaning roller, and the rotation of the cleaning roller will clean the surface of the plate member. There may be dirt, dust, oil stains, fingerprints and other impurities on the surface of the plate member, which will affect the uniformity and adhesion of inkjet. Cleaning the surface can avoid these impurities from affecting the inkjet process, ensuring the uniformity and detail performance of inkjet. The rotation of the rotating buckle will limit the fixing plate, preventing the operator from rotating the fixing plate to replace the cleaning roller when cleaning the plate member, resulting in incomplete cleaning of the surface of the plate member.

The pushing plate 9 is fixedly installed at the output end of the electric push rod 8. The sliding plate 10 is slidably installed on the inner wall of the processing frame 4. The elastic telescopic rod 12 is fixedly installed on the inner wall of the processing frame 4. The pushing plate 13 is fixedly installed at the movable end of the elastic telescopic rod 12. The clamping plate 15 is fixedly installed on the side of the pushing plate 13 away from the elastic telescopic rod 12. One end of the rotating plate 11 is rotatably installed at the bottom of the sliding plate 10, and the other end of the rotating plate 11 is rotatably installed at the top of the pushing plate 13. The rotating plate 14 is rotatably installed at the top of the pushing plate 13. One end of the push rod 16 is fixedly installed at the top of the clamping plate 15, and the other end of the push rod 16 is rotatably installed at the side of the rotating plate 14 close to the clamping plate 15. When the pushing plate 9 moves downward, it will push the sliding plate 10 to move. The movement of the sliding plate 10 will push the rotating plate 11 to move. The movement of the rotating plate 11 will push the pushing plate 13 to move towards the position of the plate member, ensuring that the plate member will not move randomly when inkjet printing is performed on the plate member, and avoiding deviation in the printing position caused by the movement of the plate member.

[0021] A first spring is provided between the sliding plate 10 and the processing frame 4. The first spring is provided to drive the sliding plate 10 back to its original position. A first torsion spring is provided between the rotating plate 14 and the pushing plate 13. The first torsion spring is provided to drive the rotating plate 14 back to its original position. A second spring is provided between the pushing plate 13 and the clamping plate 15. The second spring is provided to push the pushing plate 13 back to its original position. The control end of the detector 7 is electrically connected to the electric push rod 8.

[0022] When this embodiment works: When it is necessary to print on the surface of the metal plate member, the plate member will be placed on the surface of the transportation device 3 for transportation. When the detector 7 detects that the plate member is transported into the processing frame 4, the control end of the detector 7 will control the electric push rod 8 to start. The start of the electric push rod 8 will push the pushing plate 9 to move downward. The movement of the pushing plate 9 will push the ink outlet 6 to move. When the ink outlet 6 moves to an appropriate position from the surface of the plate member, inkjet printing will be performed on the surface of the plate member. When the pushing plate 9 moves downward, it will push the sliding plate 10 to move. The movement of the sliding plate 10 will push the rotating plate 11 to move. The movement of the rotating plate 11 will push the pushing plate 13 to move towards the position of the plate member. When the pushing plate 13 moves, it will push the clamping plate 15 to move to clamp the plate member. When the clamping plate 15 contacts the plate member, the clamping plate 15 will move towards the pushing plate 13 due to the reaction force of the plate member. When the clamping plate 15 moves towards the pushing plate 13, it will drive the push rod 16 to move. When the push rod 16 moves, it will push the rotating plate 14 to rotate. The rotation of the rotating plate 14 will block a certain degree of the surface of the plate member, preventing ink from splashing to other positions of the plate member when inkjet printing is performed on the surface of the plate member, which affects the printing accuracy of the plate member.

[0023] Please refer to Figures 1 - 7 , on the basis of the above embodiments, in another embodiment of the present invention, a positioning device and a cleaning device are further provided at the top of the support frame 1. The positioning device includes a first hydraulic cylinder 171, a first hydraulic rod 172, a second hydraulic cylinder 173, a second hydraulic rod 174 and a baffle 175. The first hydraulic cylinder 171 is fixedly installed on the inner wall of the processing frame 4. One end of the first hydraulic rod 172 is slidably installed in the inner wall of the first hydraulic cylinder 171, and the other end of the first hydraulic rod 172 is fixedly installed on the side of the push plate 13 close to the first hydraulic cylinder 171. The second hydraulic cylinder 173 is fixedly installed on the top of the support frame 1. The second hydraulic rod 174 is slidably installed in the inner wall of the second hydraulic cylinder 173. The baffle 175 is fixedly installed at the movable end of the second hydraulic rod 174. When the baffle 175 slides downwards, it will block the transported plate. When the previous plate is being inkjet printed, the next plate passes under the inspector. Since the previous plate has not completed the printing operation, the detector may automatically pause or adjust the work through the conveyor belt control system to prevent multiple plates from entering the printing area simultaneously, which may cause the equipment to jam or the printing to be uneven.

[0024] The positioning device further includes a guide plate 176 and a push rod 177. The guide plate 176 is fixedly installed on the inner wall of the support frame 1. One end of the push rod 177 is rotatably installed on the side of the baffle 175 close to the guide plate 176, and the other end of the push rod 177 is rotatably installed on the top of the guide plate 176. When the baffle 175 moves downwards, it will drive the push rod 177 to move. When the push rod 177 moves, it will push the guide plate 176 to move towards the plate, so that the plate can be in the position between the clamping plates 15 during transportation, which is convenient for clamping the plate.

[0025] The first hydraulic rod 172 has the function of sealing the first hydraulic cylinder 171, and the second hydraulic rod 174 has the function of sealing the second hydraulic cylinder 173. The first hydraulic cylinder 171 and the second hydraulic cylinder 173 are connected by a hose. A third spring is provided between the guide plate 176 and the support frame 1. The third spring is provided to drive the guide plate 176 back to its original position. The side of the guide plate 176 close to the baffle 175 is set as an inclined surface. The inclined surface of the guide plate 176 is provided to better guide the plate.

[0026] The cleaning device includes a rotating shaft 181, a large gear shaft 182, a small gear shaft 183, a rotating shaft 184, a cleaning roller 185 and a fixed plate 186. The rotating shaft 181 is fixedly installed at the output end of the transportation device 3, the large gear shaft 182 is rotatably installed on the side of the support frame 1 close to the rotating shaft 181, the fixed plate 186 is rotatably installed on the top of the support frame 1, the small gear shaft 183 rotates and passes through the fixed plate 186, the rotating shaft 184 rotates and passes through the fixed plate 186, and the cleaning roller 185 is rotatably installed on the side of the rotating shaft 184 close to the guide plate 176. The rotation of the small gear shaft 183 will drive the rotating shaft 184 to rotate, and the rotation of the rotating shaft 184 will drive the cleaning roller 185 to rotate. The rotation of the cleaning roller 185 will clean the surface of the plate. There may be impurities such as dirt, dust, oil stains, fingerprints, etc. on the surface of the plate that will affect the uniformity and adhesion of inkjet. Cleaning the surface can prevent these impurities from affecting the ink jetting process.

[0027] The cleaning device includes a fixed plate 186, a rotating buckle 187 and a T-shaped rod 188. The rotating buckle 187 is rotatably installed on the top of the support frame 1, and the T-shaped rod 188 is fixedly installed on the top of the guide plate 176. A square groove is opened on the side of the fixed plate 186 close to the rotating buckle 187. The shape of the square groove matches the rotating buckle 187. The rotation of the rotating buckle 187 will limit the fixed plate 186 to avoid the staff rotating the fixed plate 186 to replace the cleaning roller 185 when cleaning the plate, resulting in incomplete surface cleaning of the plate.

[0028] A No. 2 torsion spring is provided between the rotating buckle 187 and the support frame 1. The No. 2 torsion spring is provided to drive the rotating buckle 187 back to its original position. The T-shaped rod 188 is in contact with the rotating buckle 187. A No. 4 spring is provided between the pinion shaft 183 and the fixed plate 186. The No. 4 spring is provided to drive the pinion shaft 183 back to its original position. The rotating shaft 181 and the large gear shaft 182 are connected by a belt 1 transmission. The large gear shaft 182 matches the pinion shaft 183 in shape. The rotating shaft 184 and the pinion shaft 183 are connected by a belt 2 transmission.

[0029] During the operation of this embodiment: When the push plate 13 moves towards the plate member, it will pull the first hydraulic rod 172 to move away from the first hydraulic cylinder 171. Then, the movement of the first hydraulic rod 172 will pump the liquid inside the second hydraulic cylinder 173 into the first hydraulic cylinder 171. As a result, the liquid inside the second hydraulic cylinder 173 will decrease. The decrease in the liquid inside the second hydraulic cylinder 173 will pull the second hydraulic rod 174 to slide into the second hydraulic cylinder 173. When the second hydraulic rod 174 slides, it will pull the baffle 175 to slide downwards. The downward sliding of the baffle 175 will block the transported plate member, preventing the subsequent plate member from passing under the bottom of the checker 7 during the inkjet printing of the previous plate member, which may affect the detection of the detector 7. When the baffle 175 moves downwards, it will drive the push rod 177 to move. When the push rod 177 moves, it will push the guide plate 176 to move towards the plate member, enabling the plate member to be in a proper position during transportation for clamping.

[0030] When the guide plate 176 moves to guide the plate member, it will pull the T-shaped rod 188 to move. The movement of the T-shaped rod 188 will pull the pinion shaft 183 to slide towards the fixed plate 186. The movement of the pinion shaft 183 will engage with the large gear shaft 182. Then, when the transportation device 3 operates, it will drive the rotating shaft 181 to rotate. The rotation of the rotating shaft 181 will drive the large gear shaft 182 to rotate. When the large gear shaft 182 engages with the pinion shaft 183, the rotation of the large gear shaft 182 will drive the pinion shaft 183 to rotate. The rotation of the pinion shaft 183 will drive the rotating shaft 184 to rotate. The rotation of the rotating shaft 184 will drive the cleaning roller 185 to rotate. The rotation of the cleaning roller 185 will clean the surface of the plate member. When the T-shaped rod 188 moves and contacts the rotating buckle 187, the T-shaped rod 188 will push the rotating buckle 187 to rotate. The rotation of the rotating buckle 187 will limit the fixed plate 186, preventing the operator from rotating the fixed plate 186 to replace the cleaning roller 185 during the cleaning of the plate member, which may result in incomplete cleaning of the plate member's surface. When it is necessary to replace the cleaning roller 185, the operator will rotate the fixed plate 186. The rotation of the fixed plate 186 will drive the cleaning roller 185 to rotate towards the side away from the transportation device 3. After rotation, the operator can replace the cleaning roller 185.
