Description

Technical Field

[0001] This utility model relates to the field of plate-making machine technology, and more specifically, to a plate material protection device at the plate-making machine inlet. Background Technology

[0002] A plate processor is a tool used for developing images. Developing refers to the process of using a reducing agent to reveal the latent image formed on a film or printing plate after exposure. The development of PS plates is to obtain a printing plate surface and plate performance that meet the printing requirements while the image on the printing plate is revealed.

[0003] A search revealed that utility model patent CN213601040U discloses a protective device for the plate inlet of a plate-making machine. The device includes a plate-making machine body and an inlet table. The plate-making machine body has an inlet, and the inlet table is located at the front end of the inlet, connecting to the lower outer wall of the inlet of the plate-making machine body. The inlet table has a horizontal support plate, the inner end of which connects to the lower outer wall of the inlet, and the upper surface of the horizontal support plate is lower than the lower edge of the inlet. A smooth protective film is provided on the upper surface of the horizontal support plate, extending to the side wall of the outer end of the horizontal support plate. A guide frame is provided between the inlet table and the inlet, with the top of the guide slope of the guide frame higher than the lower surface inside the inlet. This patent has a simple structure and solves the problems of easy scratching of the plate material at the inlet and plate jamming at the inlet connection, thus improving production efficiency and product quality.

[0004] However, the aforementioned patents still have the following shortcomings: they are not convenient for automatically feeding the plate material into the plate-making machine; at the same time, when the plate material moves on the guide slope, there will be a certain amount of friction between the plate material and the guide slope, which will also cause damage to the plate material; and when the plate material is removed from the plate holder, sliding friction will also occur between the plate materials, which will also cause damage to the plate material. To address these issues, we propose a plate material protection device for the plate-making machine's inlet. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a plate material protection device at the plate inlet of a plate punching machine.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A plate material protection device for the inlet of a plate stamping machine includes a plate stamping machine body. An inlet is provided on the side of the plate stamping machine body. Two conveyor frames are fixedly connected to the side of the plate stamping machine body. The inner sides of the two conveyor frames are flush with the two sides of the inner cavity of the inlet. Two conveyor rollers are rotatably connected between the two conveyor frames. A conveyor belt is driven between the two conveyor rollers. A first motor is fixedly installed on the outer side of one of the conveyor frames. The output shaft of the first motor is connected to one end of the shaft of a conveyor roller. Multiple support rods are fixedly connected to the side of the plate stamping machine body. L-shaped support plates are fixedly connected to the ends of the multiple support rods. Multiple first electric push rods are fixedly installed on the bottom surface of the L-shaped support plates. Lifting platforms are fixedly connected to the top ends of the multiple first electric push rods. A feeding mechanism is provided on the top of the L-shaped support plate.

[0008] In a preferred embodiment of this utility model, the feeding mechanism includes two movable boxes fixedly connected to the top surface of an L-shaped support plate. The inner cavities of the two movable boxes are rotatably connected to lead screws, and movable seats are threaded onto the outer sides of the two lead screws. Movable plates are fixedly connected to the top ends of the two movable seats. Second motors are fixedly installed at the ends of the two movable boxes, and the output shafts of the two second motors are connected to the ends of the two lead screws. Multiple second electric push rods are fixedly installed on the top surface of the movable plate. The output ends of the multiple second electric push rods extend to the bottom of the movable plate and are fixedly connected to an adsorption box. Multiple adsorption holes are provided on the bottom surface of the adsorption box. A first contact sensor is fixedly installed on the top surface of the adsorption box. An air pump is fixedly installed on the side of the adsorption box, and the input end of the air pump extends into the inner cavity of the adsorption box. A second contact sensor is provided at one end of the inner cavity of one movable box, and a third contact sensor is provided at the other end of the inner cavity of the other movable box.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed on the outer side of one of the conveyor frames. The control panel is electrically connected to a first motor, a first electric push rod, a second motor, a second electric push rod, an air pump, a second contact sensor, a third contact sensor, and a first contact sensor.

[0010] In a preferred embodiment of this utility model, the side of the movable seat is fitted to the inner wall of the movable box.

[0011] As a preferred embodiment of this utility model, the two sides of the conveyor belt are respectively attached to the inner sides of the two conveyor frames.

[0012] In a preferred embodiment of this utility model, the top surface of the conveyor belt is flush with the bottom surface of the inlet cavity.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, the first motor drives the conveyor roller and the conveyor belt to rotate clockwise. The rotation of the conveyor belt feeds the plate material on the conveyor belt from the plate inlet into the plate punching machine body for processing. This realizes the function of automatically feeding the plate material into the plate punching machine body. The inner wall of the conveyor frame can block and limit the plate material conveyed on the conveyor belt, preventing the plate material from falling off the side of the conveyor belt and preventing the plate material from hitting the side of the plate punching machine body, ensuring that the conveyor belt can smoothly feed the plate material into the plate punching machine body.

[0015] (2) In this utility model, the lifting platform is used to stack the plates. The first electric push rod drives the lifting platform to move up step by step. In addition, the suction pump is used to generate suction in the suction hole below the suction box, thereby adsorbing the plates at the bottom of the suction box. The second electric push rod drives the suction box and the plates to move up a certain height. The screw thread between the lead screw and the moving seat is used to move the adsorbed plates to the top of the conveyor belt so that the plates can be placed on the conveyor belt for conveying. This realizes the function of placing the plates one by one on the conveyor belt, effectively avoiding the problem of friction between the plates, and has good practicality.

The side of the adsorption box 18 is fixedly installed with an air pump 21. The input end of the air pump 21 extends into the inner cavity of the adsorption box 18. A second contact sensor 22 is provided at one end of the inner cavity of a movable box 12, and a third contact sensor 23 is provided at the other end of the inner cavity of a movable box 12.

[0028] For details, please refer to Figures 1 to 3 A control panel 24 is fixedly installed on the outside of a conveyor frame 3. The control panel 24 is electrically connected to the first motor 6, the first electric push rod 9, the second motor 16, the second electric push rod 17, the air pump 21, the second contact sensor 22, the third contact sensor 23, and the first contact sensor 20.

[0030] For details, please refer to Figure 3 The side of the movable base 14 fits against the inner wall of the movable box 12.

[0031] In this embodiment, the inner wall of the movable box 12 is used to limit the movable seat 14, so that the movable seat 14 can only move along the axial direction of the lead screw 13.

[0032] For details, please refer to Figure 1 and Figure 2 The two sides of the conveyor belt 5 are respectively attached to the inner sides of the two conveyor frames 3.

[0033] In this embodiment, the inner side of the conveyor frame 3 is used to limit the conveyor belt 5, ensuring the stability of the conveyor belt 5 on the two conveyor rollers 4 and preventing the conveyor belt 5 from deviating.

[0034] For details, please refer to Figure 2 The top surface of the conveyor belt 5 is flush with the bottom surface of the inner cavity of the inlet 2.

[0035] In this embodiment, it is ensured that the plate material on the conveyor belt 5 can smoothly enter the plate-making machine body 1 from the plate inlet 2.

[0036] Working Principle: In operation, the plates to be processed are first stacked and placed on the lifting platform 10. Simultaneously, the second electric push rod 17 is activated to move the adsorption box 18 downwards a certain distance. The first electric push rod 9 is activated to move the lifting platform 10 and the plates upwards. When the top surface of the uppermost plate contacts the first contact sensor 20, the control panel 24 controls the first electric push rod 9 to close, and simultaneously activates the suction pump 21 to draw air from the inner cavity of the adsorption box 18, thereby generating suction through the adsorption holes 19 at the bottom of the adsorption box 18. This allows the adsorption box 18 to adsorb and fix the uppermost plate. Then, the second electric push rod 17 is activated to move the adsorption box 18 and the plates upwards. At this point, the bottom surface of the plates is higher than the top surface of the conveyor belt 5. Simultaneously, two second motors 16 are activated to rotate two lead screws 13. Through the threaded engagement between the lead screws 13 and the moving seat 14, the moving seat 14, the moving plate 15, the adsorption box 18, and the plates move. When the end of one moving seat 14 contacts the third contact sensor 23, the adsorption box 18 is activated. Control panel 24 shuts off the second motor 16. At this time, the plate material moves above the conveyor belt 5. The suction pump 21 is turned off, causing the suction force of the suction hole 19 to disappear, allowing the plate material to be placed on the conveyor belt 5. Finally, the first motor 6 is started to drive a conveyor roller 4 to rotate. The conveyor roller 4 drives the conveyor belt 5 to rotate clockwise. The conveyor belt 5 transports the plate material that falls onto it from the plate inlet 2 into the plate punching machine body 1 for processing. In addition, the second motor 16 is started to drive the lead screw 13 to reverse, thereby driving the moving seat 14, the moving plate 15 and the second electric push rod 17 to move in the opposite direction to reset. When the end of the moving seat 14 contacts the second contact sensor 22, the control panel 24 shuts off the second motor 16 again. At the same time, the second electric push rod 17 drives the suction box 18 to move down, and the first electric push rod 9 continues to drive the lifting platform 10 to move up. The lifting platform 10 continues to drive the stacked plate material to move up, so that the plate material can continue to be transported through the suction box 18, so as to realize the feeding of the plate material.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
