Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular relates to a feeding device for a watermarking machine. Background Technology

[0002] In the paper production industry, watermarking machines are key equipment for printing patterns and text on the surface of paperboard. They consist of a conveying mechanism and a movable watermarking roller. The feeding device is the starting point of the watermarking machine production process. When watermarking paperboard, the paperboard needs to be placed at the feeding point of the watermarking machine.

[0003] Currently, cardboard is mostly fed using mechanical grippers in conjunction with a rotating mechanism. However, mechanical grippers are not easy to control the clamping force, and clamping can easily damage the carton. In addition, this feeding method makes it difficult to control the number of cards clamped, and clamping too many cards will cause some cardboard to stack up and not be able to be watermarked. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a watermarking machine feeding device. By setting a base, a first electric hydraulic push rod, and a support plate, cardboard can be placed. By setting a feeding and discharging mechanism and a cooperating moving mechanism, the cardboard can be sucked up and discharged. The suction cup feeding method can feed one cardboard at a time, avoiding the situation where some cardboards cannot be watermarked due to stacking. It can also effectively avoid damage to the cardboard and ensure the processing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A watermarking machine feeding device includes a watermarking machine frame, a base, a moving mechanism, and a feeding / receiving mechanism. The base is located below the feeding port of the watermarking machine frame. Support legs are fixed around the bottom of the base, and casters are movably connected to the bottom ends of the support legs. First electro-hydraulic push rods are fixed around the top of the base, and a support plate is fixed to the telescopic end of each push rod. A fixed frame with an "L"-shaped structure is fixed to the upper side of the watermarking machine frame. The moving mechanism includes a fixed plate, a screw, a servo motor, and a moving block. A fixed plate is fixed to the bottom left end of the fixed frame. A screw is rotatably connected to the inner vertical end of the fixed plate and the fixed frame. A moving block is screwed onto the screw and slidably connected to the bottom horizontal end of the fixed frame. A servo motor connected to the screw is installed on the right side of the fixed frame. The feeding / receiving mechanism includes a second electro-hydraulic push rod, an air box, an air inlet pipe, an air pump, an air delivery pipe, and a suction cup. The moving block... A second electro-hydraulic push rod is installed on the bottom side of the machine. An air box is fixed to the telescopic end of the second electro-hydraulic push rod. An air inlet pipe is installed at the air inlet on the left side of the air box, and an air pump is installed at the air outlet on the upper side of the air box. Air supply pipes are installed at the air inlets at the four corners of the bottom side of the air box. Electric valves are installed on both the air inlet pipe and the air supply pipe. Suction cups are installed at the air inlets on the bottom side of the air supply pipe. The suction cups are rubber suction cups. The cardboard can be placed by setting up a base, a first electro-hydraulic push rod, and a support plate. The cardboard can be sucked and unloaded by setting up a feeding and unloading mechanism and a moving mechanism. The suction cup feeding method can feed one cardboard at a time, avoiding the situation where some cardboards cannot be printed due to stacking. It can also effectively avoid damage to the cardboard and ensure processing quality. By setting support legs around the bottom side of the base and installing universal wheels at the bottom of the support legs, it is easier to move the cardboard to the watermarking machine frame, improving the flexibility of use.

[0007] Furthermore, a limiting plate is fixed to the upper end of each support plate. By setting the limiting plate, the neatness of the cardboard is ensured and the cardboard is prevented from falling off the support plate.

[0008] Furthermore, a position sensor is installed on the left side of the watermarking machine frame. The position sensor monitors the position of the top of the limiting plate in real time. When a piece of cardboard is loaded, the first electric hydraulic push rod drives the support plate to move upward until the top of the limiting plate is at the same level as the position sensor, ensuring that the suction cup can adsorb subsequent cardboard.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The cardboard can be placed by setting a base, a first electric hydraulic push rod, and a support plate. The cardboard can be sucked and unloaded by setting a feeding and unloading mechanism and a moving mechanism.

It can also effectively avoid damage to the cardboard and ensure processing quality. By setting support legs around the bottom of the base and installing universal wheels at the bottom of the support legs, it is easier to move the cardboard to the watermarking machine frame, improving the flexibility of use.

[0011] 2. By setting a limiting plate, the neatness of the cardboard is ensured and the cardboard is prevented from falling off the support plate. The position sensor monitors the position of the top of the limiting plate in real time. When a cardboard is loaded, the first electric hydraulic push rod drives the support plate to move upward until the top of the limiting plate is at the same level as the position sensor, ensuring that the suction cup can adsorb the subsequent cardboard.

[0017] See appendix Figure 1-2 As shown, a watermarking machine feeding device includes a watermarking machine frame 1, a base 2, a moving mechanism 8, and a feeding / receiving mechanism 9. The base 2 is located below the feeding port of the watermarking machine frame 1. Support legs 3 are fixed around the bottom of the base 2, and casters 4 are movably connected to the bottom ends of the support legs 3. First electro-hydraulic push rods 5 are fixed around the top of the base 2. Support plates 6 are fixed to the telescopic ends of the first electro-hydraulic push rods 5. A fixing frame 7 is fixed on the upper side of the watermarking machine frame 1. The fixing frame 7 has an "L" shaped structure. The moving mechanism 8 includes a fixing plate 8. 1. A screw 82, a servo motor 83, and a moving block 84 are included. A fixing plate 81 is fixed to the bottom left side of the fixing frame 7. A screw 82 is rotatably connected to the inner side of the vertical end of the fixing plate 81 and the fixing frame 7. A moving block 84 is screwed onto the screw 82. The moving block 84 is slidably connected to the bottom horizontal end of the fixing frame 7. A servo motor 83 connected to the screw 82 is installed on the right side of the fixing frame 7. The feeding and receiving mechanism 9 includes a second electric hydraulic push rod 91, an air box 92, an air inlet pipe 93, an air pump 94, an air delivery pipe 95, and a suction cup 96. A second electro-hydraulic push rod 91 is installed on the bottom side of the movable block 84. An air box 92 is fixed to the telescopic end of the second electro-hydraulic push rod 91. An air inlet pipe 93 is installed at the air inlet on the left side of the air box 92. An air pump 94 is installed at the air outlet on the upper side of the air box 92. Air supply pipes 95 are installed at the air inlets at the four corners of the bottom side of the air box 92. Electric valves are installed on both the air inlet pipe 93 and the air supply pipe 95. Suction cups 96, which are rubber suction cups, are installed at the air inlets on the bottom side of the air supply pipes 95. This is achieved by setting a base 2 and a first electric... The hydraulic push rod 5 and the support plate 6 can place the cardboard. By setting up the feeding and receiving mechanism 9 and cooperating with the moving mechanism 8, the cardboard can be sucked and released. The suction cup feeding method can feed one cardboard at a time, avoiding the situation where some cardboards cannot be printed due to stacking. It can also effectively avoid damage to the cardboard and ensure the processing quality. By setting the support legs 3 around the bottom of the base 2 and setting the universal wheels 4 at the bottom of the support legs 3, it is easier to move the cardboard to the watermarking machine frame 1, improving the flexibility of use.

[0018] Limiting plates 10 are fixed to the upper end of the support plate 6. By setting the limiting plates 10, the neatness of the cardboard is ensured and the cardboard is prevented from falling off the support plate 6.

[0019] A position sensor 11 is installed on the left side of the watermark machine frame 1. The position sensor 11 monitors the position of the top of the limit plate 10 in real time. When a piece of cardboard is loaded, the first electric hydraulic push rod 5 drives the support plate 6 to move upward until the top of the limit plate 10 is on the same horizontal plane as the position sensor 11, so as to ensure that the suction cup 96 can adsorb the subsequent cardboard.

[0020] Working principle: Cardboard is stacked on support plate 6. The second electro-hydraulic push rod 91 extends, thereby moving the air box 92 downward until the suction cup 96 contacts the cardboard to be loaded. Then, the air pump 94 extracts the air from the air box 92, reducing the pressure inside. The electric valve on the air supply pipe 95 is opened. Due to the reduced pressure at the suction cup 96, the cardboard is adsorbed onto the suction cup 96. The second electro-hydraulic push rod 91 moves the air box 92 and the cardboard upward. The servo motor 92 drives the moving block 84 through the screw 82, thereby moving the second electro-hydraulic push rod 91, the air box 92, and the cardboard until the cardboard is above the left end of the watermark machine frame 1. Then, the electric valve on the air inlet pipe 93 is opened, and external air enters the air box 92, causing the adhesion between the suction cup 95 and the cardboard to decrease. Due to the weight of the cardboard, it falls. The paperboard is fed to the feeding port at the left end of the watermarking machine frame 1, and the above steps are repeated. A suction cup feeding method is used, which can feed one paperboard at a time, avoiding the situation where some paperboards cannot be watermarked due to stacking. It can also effectively avoid damage to the paperboard and ensure processing quality. By setting support legs 3 around the bottom of the base 2 and setting universal wheels 4 at the bottom of the support legs 3, it is easier to move the paperboard to the watermarking machine frame 1, improving the flexibility of use. By setting a limit plate 10, the neatness of the paperboard is ensured and the paperboard is prevented from falling off the support plate 6. The position sensor 11 monitors the position of the top of the limit plate 10 in real time. After feeding one paperboard, the first electric hydraulic push rod 5 drives the support plate 6 to move upward until the top of the limit plate 10 is at the same level as the position sensor 11, ensuring that the suction cup 96 can adsorb the subsequent paperboard.
