Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a printing device based on green printing technology. Background Art

[0002] Green printing technology utilizes environmentally friendly materials and processes to reduce pollution, conserve resources and energy, and ensure easy recycling of discarded printed products. Furthermore, these printing units are equipped with various auxiliary systems, such as ink matching systems, automatic blanket washers, and dust collection devices, to further enhance environmental performance and efficiency. By utilizing these advanced technologies and equipment, green printing technology can meet printing needs while minimizing environmental impact.

[0003] In the current field of green printing technology, magnesium powder is widely used as a key auxiliary material in specific process steps, accelerating ink drying, improving print quality, and acting as a catalyst for certain chemical reactions. Magnesium powder is typically packaged in plastic bags, which leads to inevitable errors and uncertainties during manual addition of magnesium powder to the printing press, leading to frequent leakage. Magnesium powder particles are light and easily dispersed. Once leaked, they not only cause serious pollution to the production environment and affect the normal operation of other equipment, but can also enter the human body through the respiratory tract, posing a direct threat to the health of operators and causing respiratory problems or other health damage. Utility Model Content

[0004] The purpose of the present utility model is to provide a printing device based on green printing technology to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A printing device based on green printing technology includes a printing device body, a shell fixedly connected to the printing device body, the shell being L-shaped, a cover plate provided above the shell, the cover plate being slidably connected to the box body, a placement plate symmetrically provided and fixedly connected inside the shell, guide grooves symmetrically provided inside the shell, a vertical groove provided inside the shell, both the vertical groove and the guide groove being located below the placement plate, and a first cavity provided inside the shell;

[0007] A clamping component is located inside the shell and is used in conjunction with the placement plate to clamp bagged magnesium powder;

[0008] A cutting component is located below the clamping component and is used in conjunction with the guide groove and the vertical groove to cut the packaging bag;

[0009] The auxiliary component is located outside the shell and is used to assist magnesium powder in entering the first cavity.

[0010] When magnesium powder needs to be added into the device, the sliding cover opens the cover, and then the bagged magnesium powder is placed on the placement plate between the clamping parts. The sliding cover makes the shell a closed space. At this time, the clamping parts have clamped the bagged magnesium powder, and then the cutting parts are started to cut the clamped cutting parts, so that the bagged magnesium powder breaks. At this time, the magnesium powder in the packaging bag will fall and then be transported to the inside of the first cavity through the auxiliary parts. The first cavity is connected to the silo in the printing device body, so that the magnesium powder can enter the silo through the first cavity after the auxiliary parts are closed, thereby achieving loading while avoiding leakage of magnesium powder.

[0011] A further improvement of the technical solution of the present utility model is that: the clamping component includes a rotating shaft and a clamping plate, the rotating shaft and the clamping plate are symmetrically arranged, the rotating shaft is rotatably connected to the shell, some areas on the rotating shaft are symmetrically provided with thread grooves, the clamping plate is threadedly connected to the rotating shaft through the thread grooves, one end of the rotating shaft is fixedly connected to a gear, and both ends of the cover plate are symmetrically arranged and fixedly connected to a rack, the gear and the rack are meshed, one side of the clamping plate is in contact with the placement plate and is slidably connected to the shell.

[0012] The above technical solution is adopted. In this solution, when it is necessary to clamp the bagged magnesium powder, the cover plate is slid, and the cover plate drives the rack fixedly connected to it to move. At this time, the rack drives the gear meshing with it to rotate, thereby driving the rotating shaft to rotate. The rotating shaft rotates and because one side of the clamping plate contacts the placement plate and is slidably connected to the shell, it drives the clamping plate threadedly connected to it to move toward or in the opposite direction of the axis of the rotating shaft. Then the bagged magnesium powder is placed in and the clamping action is achieved through cooperation with the placement plate. Therefore, the position of the clamping plate can be controlled by controlling the movement of the cover plate to achieve the action of clamping the packaging bag.

[0013] A further improvement of the technical solution of the present utility model is that the cutting part includes a bottom rod, which is slidably connected to the shell through a vertical groove, and a sliding block is symmetrically arranged on the bottom rod for sliding connection, a blade is fixedly connected above the sliding block, and guide rods are symmetrically arranged and fixedly connected on both sides of the sliding block, and the guide rods are slidably connected to the guide groove.

[0014] The above technical solution adopts this solution. In this solution, after the clamping component clamps the packaging bag, it can move the bottom rod upward. At this time, the bottom rod will drive the sliding block connected to it to move upward. Because the guide rods on both sides of the sliding block are slidably connected to the guide groove, the sliding block will first move upward to drive the blade to pierce the packaging bag. Then, under the action of the bottom rod and the guide groove, it will move to both sides, thereby cutting the packaging bag open. The magnesium powder in the packaging bag will float down through the first cavity into the silo, and the empty packaging bag will hang on the blade, thereby achieving the purpose of loading. This can prevent the magnesium powder from leaking. When it is necessary to remove the bag, open the cover, then take out the packaging bag, and reset the connecting rod to resume the cycle.

[0015] A further improvement of the technical solution of the present utility model is that: the cutting part also includes a connecting rod, the connecting rod is arranged in a C shape, the connecting rod is slidably connected to the shell, one end of the connecting rod is fixedly connected to the bottom rod, and the other end of the connecting rod is fixedly connected to the box body, and the two ends of the box body are symmetrically provided with a return spring and a card block, one end of the return spring is fixedly connected to the card block, and the other end of the return spring is fixedly connected to the box body, and a stop block is symmetrically arranged and fixedly connected on the shell, and the stop block and the card block are used in conjunction with each other.

[0016] The above technical solution is adopted. In this solution, after the clamping plate clamps the bagged magnesium powder, it pinches the block at one end of the connecting rod. At this time, the block is located inside the box body, and the return spring is in a compressed state. Then it moves upward until it moves above the block. At this time, the power is transmitted to the bottom rod through the connecting rod, and then the block is released. The block is reset under the action of the return spring, thereby fixing the block and providing support force for the bottom rod.

[0017] A further improvement of the technical solution of the present utility model is that the auxiliary components include an air pump and a storage tank, an air inlet is provided at one end of the shell, the air inlet is located above the placement plate, an exhaust port is provided on one side of the first cavity, a filter is provided at the exhaust port, the air inlet, the air pump exhaust port and the storage tank are respectively connected by pipes, and a one-way valve is fixedly connected to the air inlet and the exhaust port.

[0018] The above-mentioned technical solution is adopted. In this solution, when the blade cuts the packaging bag, the inert gas in the storage tank is input into the interior of the shell through the air inlet by the air pump. After flowing inside, the inert gas is discharged into the storage tank from the exhaust port at the bottom for circulation. At the same time, the input of the inert gas will drive the magnesium powder to move toward the first cavity, preventing the magnesium powder from floating to the cover and adhering to it, thereby preventing the magnesium powder from leaking when the cover is opened. When there is still a small amount of magnesium powder in the packaging bag, the airflow will cause the packaging bag to shake, thereby reducing the residual magnesium powder in the packaging bag.

[0019] A further improvement of the technical solution of the present utility model is that a plurality of hemispherical protrusions are evenly arranged and fixedly connected on the clamping plate.

[0020] The above technical solution is adopted, in which a plurality of hemispherical protrusions are provided, so that the contact area between the clamping plate and the packaging bag can be increased when the clamping plate clamps the packaging bag, thereby increasing the clamping friction.

[0021] A further improvement of the technical solution of the present utility model is that one end of the rack is fixedly connected to the limiting tooth.

[0022] The above technical solution is adopted. In this solution, when the rack and the gear are engaged with each other, the rack will be disengaged due to motion overload, which will not only affect the stability of the power transmission work, but also cause the device to malfunction. By setting a limit tooth at one end of the rack in a fixed connection, the rack and the gear can be prevented from being disengaged when they are engaged with each other.

[0023] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0024] 1. The utility model provides a printing device based on green printing technology. When magnesium powder needs to be added to the device, the sliding cover opens the cover, and then the bagged magnesium powder is placed on the partial placement plate between the clamping parts. The sliding cover makes the shell into a closed space. At this time, the clamping parts have clamped the bagged magnesium powder, and then the cutting parts are started to cut the clamped cutting parts, so that the bagged magnesium powder breaks. At this time, the magnesium powder in the packaging bag will fall and then be transported to the inside of the first cavity through the auxiliary parts. The first cavity is connected to the silo in the printing device body, so that the magnesium powder can enter the silo through the first cavity after the auxiliary parts are closed, thereby achieving loading while avoiding leakage of magnesium powder.

[0025] 2. The utility model provides a printing device based on green printing technology. When it is necessary to clamp bagged magnesium powder, the cover plate is slid, and the cover plate drives the rack fixedly connected to it to move. At this time, the rack drives the gear meshing with it to rotate, thereby driving the rotating shaft to rotate. The rotating shaft rotates and because one side of the clamping plate contacts the placement plate and is slidably connected to the shell, it drives the clamping plate threadedly connected to it to move toward or in the opposite direction of the axis of the rotating shaft. Then the bagged magnesium powder is placed in and the clamping action is achieved through cooperation with the placement plate. Therefore, the position of the clamping plate can be controlled by controlling the movement of the cover plate to achieve the action of clamping the packaging bag.

[0026] 3. The utility model provides a printing device based on green printing technology. After the clamping component clamps the packaging bag, the bottom rod can be moved upward. At this time, the bottom rod will drive the sliding block connected to it to move upward. Because the guide rods on both sides of the sliding block are slidably connected to the guide groove, the sliding block will first move upward to drive the blade to pierce the packaging bag. Then, under the action of the bottom rod and the guide groove, it will move to both sides, thereby cutting the packaging bag open. The magnesium powder in the packaging bag will float down through the first cavity to the inside of the silo, and the empty packaging bag will hang on the blade, thereby achieving the purpose of loading, which can prevent the magnesium powder from leaking. When it needs to be taken out, open the cover, then take out the packaging bag, reset the connecting rod to start the cycle operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention is further described in detail below with reference to the embodiments:

[0037] Example

[0038] like Figure 1 As shown, the utility model provides a printing device based on green printing technology, comprising:

[0039] The printing device body 1 has a housing 2 fixedly connected to the printing device body 1. The housing 2 is L-shaped. A cover plate 3 is provided above the housing 2. The cover plate 3 is slidably connected to the box body 18. A placement plate 4 is symmetrically provided and fixedly connected inside the housing 2. Guide grooves 5 are symmetrically provided inside the housing 2. A vertical groove 6 is provided inside the housing 2. Both the vertical groove 6 and the guide groove 5 are located below the placement plate 4. A first cavity 7 is provided inside the housing 2.

[0040] The clamping component is located inside the housing 2 and is used in conjunction with the placement plate 4 to clamp the bagged magnesium powder;

[0041] A cutting component is located below the clamping component and is used in conjunction with the guide groove 5 and the vertical groove 6 to cut the packaging bag;

[0042] Auxiliary component: The auxiliary component is located outside the shell 2 and is used to assist magnesium powder to enter the first cavity 7.

[0043] In this embodiment, when magnesium powder needs to be added to the device, the sliding cover 3 opens the cover 3, and then the bagged magnesium powder is placed on the partial placement plate 4 between the clamping parts. The sliding cover 3 makes the shell 2 in a closed space. At this time, the clamping part has clamped the bagged magnesium powder, and then the cutting part is started to cut the clamped cutting part, so that the bagged magnesium powder breaks. At this time, the magnesium powder in the packaging bag will fall and then be transported to the inside of the first cavity 7 through the auxiliary part. The first cavity 7 is connected to the silo in the printing device body 1, so that the magnesium powder can enter the silo through the first cavity 7 after the auxiliary part is closed, thereby achieving loading while avoiding leakage of magnesium powder.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, preferably, the clamping component includes a rotating shaft 8 and a clamping plate 9, the rotating shaft 8 and the clamping plate 9 are symmetrically arranged, the rotating shaft 8 is rotatably connected to the shell 2, and a partial area on the rotating shaft 8 is symmetrically opened with a thread groove 10, the clamping plate 9 is threadedly connected to the rotating shaft 8 through the thread groove 10, one end of the rotating shaft 8 is fixedly connected to a gear 11, and the two ends of the cover plate 3 are symmetrically arranged and fixedly connected with a rack 12, the gear 11 is engaged with the rack 12, and one side of the clamping plate 9 is in contact with the placement plate 4 and is slidably connected to the shell 2.

[0045] When it is necessary to clamp the bagged magnesium powder, the sliding cover plate 3 will drive the rack 12 fixed to it to move. At this time, the rack 12 will drive the gear 11 meshing with it to rotate, thereby driving the rotating shaft 8 to rotate. The rotating shaft 8 rotates and because one side of the clamping plate 9 is in contact with the placement plate 4 and is slidingly connected to the shell 2, it drives the clamping plate 9 threadedly connected to it to move toward or in the opposite direction of the axis of the rotating shaft 8, and then the bagged magnesium powder is placed in and the clamping action is achieved through cooperation with the placement plate 4. Therefore, the position of the clamping plate 9 can be controlled by controlling the movement of the cover plate 3 to achieve the action of clamping the packaging bag.

[0046] like Figure 4 and Figure 5 As shown, preferably, the cutting component includes a bottom rod 13, which is slidably connected to the shell 2 through a vertical groove 6, and a sliding block 14 is symmetrically arranged on the bottom rod 13 for sliding connection, and a blade 15 is fixedly connected above the sliding block 14, and guide rods 16 are symmetrically arranged and fixedly connected on both sides of the sliding block 14, and the guide rods 16 are slidably connected to the guide groove 5.

[0047] After the clamping member clamps the bag, the bottom rod 13 can be moved upward, which will drive the sliding block 14 slidably connected thereto to move upward. Because the guide rods 16 on both sides of the sliding block 14 are slidably connected to the guide groove 5, the sliding block 14 will first move upward to drive the blade 15 to pierce the bag. Then, under the action of the bottom rod 13 and the guide groove 5, it will move to both sides, thereby cutting the bag open. The magnesium powder in the bag will float downward through the first cavity 7 to the inside of the silo, and the empty bag will hang on the blade 15, thereby achieving the purpose of loading and preventing magnesium powder from leaking. When it is necessary to take out, the cover 3 is opened, the bag is taken out, and the connecting rod 17 is reset to resume the cycle.

[0048] like Figure 4 and Figure 7 As shown, preferably, the cutting component also includes a connecting rod 17, which is arranged in a C shape, and is slidingly connected to the shell body 2. One end of the connecting rod 17 is fixedly connected to the bottom rod 13, and the other end of the connecting rod 17 is fixedly connected to the box body 18. The two ends of the box body 18 are symmetrically provided with a return spring 19 and a block 20, one end of the return spring 19 is fixedly connected to the block 20, and the other end of the return spring 19 is fixedly connected to the box body 18. A block 21 is symmetrically arranged and fixedly connected on the shell body 2, and the block 21 is used in conjunction with the block 20.

[0049] After the clamping plate 9 clamps the bagged magnesium powder, it pinches the block 20 at one end of the connecting rod 17. At this time, the block 20 is located inside the box body 18, and the return spring 19 is in a compressed state. Then it moves upward until it moves above the stopper 21. At this time, the power is transmitted to the bottom rod 13 through the connecting rod 17, and then the block 20 is released. The block 20 is reset under the action of the return spring 19, thereby fixing the block 20 and providing support force for the bottom rod 13.

[0050] like Figure 3 and Figure 4 As shown, preferably, the auxiliary components include an air pump 22 and a storage tank 23, an air inlet is provided at one end of the shell 2, the air inlet is located above the placement plate 4, an exhaust port is provided on one side of the first cavity 7, a filter screen 26 is provided at the exhaust port, the air inlet, the exhaust port of the air pump 22 and the storage tank are respectively connected by pipes, and a one-way valve is fixedly connected to the air inlet and the exhaust port.

[0051] After the blade 15 cuts the packaging bag, the inert gas in the storage tank is input into the interior of the shell 2 through the air inlet through the air pump 22. After flowing inside, the inert gas is discharged into the storage tank from the exhaust port at the bottom for circulation. At the same time, the input of the inert gas will drive the magnesium powder to move toward the first cavity 7, preventing the magnesium powder from floating toward the cover 3 and adhering to it, thereby preventing the magnesium powder from leaking when the cover 3 is opened. When there is still a small amount of magnesium powder in the packaging bag, the airflow will cause the packaging bag to shake, thereby reducing the residual magnesium powder in the packaging bag.

[0052] like Figure 2 As shown, preferably, a plurality of hemispherical protrusions 24 are evenly arranged and fixedly connected to the clamping plate 9.

[0053] The provision of a plurality of hemispherical protrusions 24 can increase the contact area between the clamping plate 9 and the packaging bag when the clamping plate 9 clamps the packaging bag, thereby increasing the clamping friction.

[0054] like Figure 6 As shown, preferably, one end of the rack 12 is fixedly connected to the limiting tooth 25 .

[0055] Because when the rack 12 and the gear 11 are engaged with each other, the motion overload causes the rack 12 to be disengaged, which not only affects the stability of the power transmission work, but also causes the device to malfunction. By fixedly connecting a limit tooth 25 at one end of the rack 12, the rack 12 and the gear 11 can be prevented from being disengaged when they are engaged with each other.

[0056] The working principle of the printing device based on green printing technology is described in detail below.

[0057] like Figure 1-7As shown, when magnesium powder needs to be added into the device, the sliding cover 3 opens the cover 3, and then the bagged magnesium powder is placed on the partial placement plate 4 between the clamping parts. The sliding cover 3 makes the shell 2 in a closed space. At this time, the clamping part has clamped the bagged magnesium powder, and then the cutting part is started to cut the clamped cutting part, so that the bagged magnesium powder breaks. At this time, the magnesium powder in the packaging bag will fall and then be transported to the inside of the first cavity 7 through the auxiliary part. The first cavity 7 is connected to the silo in the printing device body 1, so that the magnesium powder can enter the silo through the first cavity 7 after the auxiliary part is closed, thereby achieving loading while avoiding leakage of magnesium powder. When it is necessary to clamp the bagged magnesium powder, the sliding cover plate 3 will drive the rack 12 fixed to it to move. At this time, the rack 12 will drive the gear 11 meshing with it to rotate, thereby driving the rotating shaft 8 to rotate. The rotating shaft 8 rotates and because one side of the clamping plate 9 is in contact with the placement plate 4 and is slidingly connected to the shell 2, it drives the clamping plate 9 threadedly connected to it to move toward or in the opposite direction of the axis of the rotating shaft 8, and then the bagged magnesium powder is placed in and the clamping action is achieved through cooperation with the placement plate 4. Therefore, the position of the clamping plate 9 can be controlled by controlling the movement of the cover plate 3 to achieve the action of clamping the packaging bag. After the clamping member clamps the bag, the bottom rod 13 can be moved upward, which will drive the sliding block 14 slidably connected thereto to move upward. Because the guide rods 16 on both sides of the sliding block 14 are slidably connected to the guide groove 5, the sliding block 14 will first move upward to drive the blade 15 to pierce the bag. Then, under the action of the bottom rod 13 and the guide groove 5, it will move to both sides, thereby cutting the bag open. The magnesium powder in the bag will float downward through the first cavity 7 to the inside of the silo, and the empty bag will hang on the blade 15, thereby achieving the purpose of loading and preventing magnesium powder from leaking. When it is necessary to take out, the cover 3 is opened, the bag is taken out, and the connecting rod 17 is reset to resume the cycle. After the clamping plate 9 clamps the bag of magnesium powder, it pinches the block 20 at one end of the connecting rod 17. At this time, the block 20 is located inside the box body 18, and the return spring 19 is in a compressed state. The block 20 then moves upward until it moves above the stopper 21. At this time, the force is transmitted to the bottom bar 13 through the connecting rod 17, and the block 20 is released. The block 20 is reset under the force of the return spring 19, thereby fixing the block 20 and providing support for the bottom bar 13. When the blade 15 cuts the bag, the inert gas in the storage tank is input into the housing 2 through the air inlet via the air pump 22. After flowing through the interior, it is discharged from the exhaust port at the bottom back into the storage tank, thus circulating. At the same time, the input of inert gas drives the magnesium powder to move toward the first cavity 7, preventing the magnesium powder from drifting to the cover plate 3 and adhering to it, thereby preventing the magnesium powder from leaking when the cover plate 3 is opened. If there is still a small amount of magnesium powder in the bag, the air flow will cause the bag to shake, thereby reducing the amount of magnesium powder remaining in the bag.The provision of several hemispherical protrusions 24 increases the contact area between the clamping plate 9 and the packaging bag when the clamping plate 9 is clamping the packaging bag, thereby increasing the clamping friction. Because when the rack 12 and the gear 11 are meshing, overload can cause the rack 12 to become dislocated, which not only affects the stability of power transmission but also causes the device to malfunction. The provision of a limit tooth 25 fixedly connected to one end of the rack 12 prevents this from occurring when the rack 12 and the gear 11 are meshing.

[0058] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
