Description

Technical Field

[0001] This utility model relates to a filtration device, specifically a raw material filtration device for color printing. Background Technology

[0002] Ink is a homogeneous mixture composed of colored substances (such as pigments and dyes), binders, fillers, and additives. It can be printed and dries on the printed surface. There are many types of inks, and their physical properties vary. Some are very thick and viscous, while others are quite thin. Some use vegetable oil as a binder, while others use resin and solvents or water. Ink is prone to sedimentation when left to stand for a long time. To ensure printing quality, it needs to be filtered during use. Existing filtration devices have low filtration efficiency when filtering raw materials. They rely solely on the gravity of the raw materials for filtration, resulting in low efficiency. Therefore, a raw material filtration device for color printing needs to be designed to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a raw material filtering device for color printing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A raw material filtration device for color printing includes a housing, in which a first filter chamber and a second filter chamber are disposed. A filter plate is installed at the bottom of the first filter chamber. A sliding groove is formed on the side wall of the second filter chamber, in which a filter screen is slidably installed. A guide groove is formed on the side wall of the first filter chamber, in which a guide rod is slidably installed. A guide plate is connected to the end of the guide rod away from the guide groove. A connecting rod is installed at the bottom of the guide plate, and a pressure plate is connected to the end of the connecting rod away from the guide plate. The pressure plate is sealed and fitted against the side wall of the first filter chamber. A feed inlet is provided on the side wall of the filter chamber, and a valve is installed on the feed inlet. A drive assembly is installed on the housing, and a transmission assembly and a transmission mechanism are installed on the drive assembly. The end of the transmission assembly away from the drive assembly is connected to the guide plate, and the end of the transmission mechanism away from the drive assembly is connected to the second filter screen.

[0006] As a further embodiment of this utility model: the drive assembly includes a dual-axis motor, the dual-axis motor is mounted on the housing, and a first drive shaft and a second drive shaft are mounted on the output end of the dual-axis motor, with the end of the first drive shaft away from the dual-axis motor extending into the housing.

[0007] As a further embodiment of this utility model: the transmission assembly includes a driven shaft, one end of which is rotatably connected to the top wall of the first filter chamber, and the other end is connected to a threaded rod, which is threadedly connected to the guide plate. A connecting unit is installed on the first drive shaft, and the end of the connecting unit away from the first drive shaft is connected to the driven shaft.

[0008] As a further embodiment of this utility model: the transmission mechanism includes a rotating shaft, one end of which is rotatably connected to the side wall of the second filter chamber, a cam is mounted on the rotating shaft, the cam is disposed on one side of the filter screen, an elastic component is mounted at the bottom of the filter screen, the end of the elastic component away from the filter screen is connected to the bottom wall of the slide groove, and a connecting mechanism is mounted on the second drive shaft, the end of the connecting mechanism away from the second drive shaft is connected to the rotating shaft.

[0009] As a further embodiment of this invention, the elastic component is a spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The raw material to be filtered is fed into one side of the filter plate through the feed inlet. Under the action of gravity, the raw material will pass through the filter plate for filtration. After preliminary filtration, the raw material will drip onto the second filter screen at the bottom, where it will be further filtered. During this process, the dual-axis motor drives the first and second drive shafts connected to it to rotate. The rotation of the first drive shaft drives the driven shaft to rotate through the connecting unit. The rotation of the driven shaft drives the threaded rod to rotate. The rotation of the threaded rod, under the action of the thread, drives the guide plate connected to it to move downward. The downward movement of the guide plate can drive the pressure plate at one end of the connecting rod to move downward. The downward movement of the pressure plate reduces the volume between the pressure plate and the raw material, thereby increasing the pressure in the space between them. This increased pressure exerts force on the raw material, allowing the filter plate to filter it more quickly and improving filtration efficiency. The rotation of the second drive shaft, through a connecting mechanism, drives the connected rotating shaft to rotate. The rotating shaft, in turn, drives the connected cam to rotate. The cam's rotation, in conjunction with the elastic component, causes the filter screen on one side to vibrate continuously. This vibration of the filter screen accelerates the filtration efficiency of the raw material and prevents the filter screen from becoming clogged due to the raw material remaining still on one side, thus improving the practicality of the device.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 As an embodiment of this utility model, a raw material filtering device for color printing includes a housing 1, in which a first filtering chamber 2 and a second filtering chamber 3 are provided. A filter plate 6 is installed at the bottom of the first filtering chamber 2. A sliding groove is formed on the side wall of the second filtering chamber 3, and a filter screen 4 is slidably installed in the sliding groove. A guide groove is formed on the side wall of the first filtering chamber 2, and a guide rod 9 is slidably installed in the guide groove. A guide plate 8 is connected to the end of the guide rod 9 away from the guide groove. A connecting rod 10 is installed at the bottom of the guide plate 8, and a pressure plate 12 is connected to the end of the connecting rod 10 away from the guide plate 8. The pressure plate 12 is sealed and fitted to the side wall of the first filtering chamber 2. A feed inlet is provided on the side wall of the filtering chamber, and a valve is installed on the feed inlet. A drive assembly is installed on the housing 1. A transmission assembly and a transmission mechanism are installed on the drive assembly. The end of the transmission assembly away from the drive assembly is connected to the guide plate 8, and the end of the transmission mechanism away from the drive assembly is connected to the second filter screen 4.

[0017] In this embodiment, the raw material to be filtered is fed into one side of the filter plate 6 through the feed inlet. Under the action of gravity, the raw material will pass through the filter plate 6 for filtration. After preliminary filtration, the raw material will drip onto the second filter screen 4 at the bottom. The second filter screen 4 will further filter the raw material. During this process, the drive component drives the transmission component connected to it to operate. The transmission component drives the guide plate 8 connected to it to move. The guide plate 8 moves downward, which can drive the pressure plate 12 at one end of the connecting rod 10 to move downward. The downward movement of the pressure plate 12 reduces the volume between the pressure plate 12 and the raw material, thereby increasing the spatial pressure between the two. The increased pressure exerts pressure on the raw material. Under the action of pressure, the filter plate 6 can filter the raw material more quickly, improving the filtration efficiency. The second drive shaft 16 drives the transmission component to operate. The transmission mechanism drives the filter screen 4 connected to it to vibrate. The vibration of the filter screen 4 accelerates the filtration efficiency of the filter screen 4 on the raw material, and at the same time, it can prevent the raw material from sitting on one side of the filter screen 4 and causing the filter screen 4 to become clogged, thus improving the practicality of the device.

[0018] As an embodiment of the present invention, the drive assembly includes a dual-axis motor 15, which is mounted on the housing 1. A first drive shaft 14 and a second drive shaft 16 are mounted on the output end of the dual-axis motor 15. The end of the first drive shaft 14 away from the dual-axis motor 15 extends into the housing 1.

[0019] In this embodiment, the dual-axis motor 15 drives the first drive shaft 14 and the second drive shaft 16 connected to it to rotate. The rotation of the first drive shaft 14 drives the transmission component connected to it to operate. The transmission component drives the guide plate 8 connected to it to move. The guide plate 8 moves downward, which can drive the pressure plate 12 at one end of the connecting rod 10 to move downward. The downward movement of the pressure plate 12 reduces the volume between the pressure plate 12 and the raw material, thereby increasing the spatial pressure between the two. The increased pressure exerts pressure on the raw material. Under the action of pressure, the filter plate 6 can filter the raw material more quickly, improving the filtration efficiency. The second drive shaft 16 drives the transmission component to operate. The transmission mechanism drives the filter screen 4 connected to it to vibrate. The vibration of the filter screen 4 accelerates the filtration efficiency of the filter screen 4 on the raw material, and at the same time, it can prevent the raw material from sitting on one side of the filter screen 4 and causing the filter screen 4 to become blocked, thus improving the practicality of the device.

[0020] As an embodiment of the present invention, the transmission assembly includes a driven shaft 7, one end of which is rotatably connected to the top wall of the first filter chamber 2, and the other end is connected to a threaded rod 11. The threaded rod 11 is threadedly connected to the guide plate 8. A connecting unit 13 is installed on the first drive shaft 14, and the end of the connecting unit 13 away from the first drive shaft 14 is connected to the driven shaft 7.

[0021] In this embodiment, the rotation of the first drive shaft 14 drives the driven shaft 7 to rotate via the connecting unit 13. The rotation of the driven shaft 7 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11, under the action of the thread, drives the guide plate 8 connected to it to move downward. The downward movement of the guide plate 8 can drive the pressure plate 12 at one end of the connecting rod 10 to move downward. The downward movement of the pressure plate 12 reduces the volume between the pressure plate 12 and the raw material, thereby increasing the spatial pressure between the two. The increased pressure exerts pressure on the raw material. Under the action of pressure, the filter plate 6 can filter the raw material more quickly, improving the filtration efficiency.

[0022] Furthermore, the connecting unit 13 can be a gear set or a worm gear and worm wheel combination, which will not be described in detail here.

[0023] As an embodiment of this utility model, the transmission mechanism includes a rotating shaft 18, one end of which is rotatably connected to the side wall of the second filter chamber 3. A cam 19 is mounted on the rotating shaft 18, and the cam 19 is disposed on one side of the filter screen 4. An elastic member 5 is mounted on the bottom of the filter screen 4, and the end of the elastic member 5 away from the filter screen 4 is connected to the bottom wall of the slide groove. A connecting mechanism 17 is mounted on the second drive shaft 16, and the end of the connecting mechanism 17 away from the second drive shaft 16 is connected to the rotating shaft 18.

[0024] In this embodiment, the rotation of the second drive shaft 16 drives the rotating shaft 18 connected to it to rotate through the connecting mechanism 17. The rotation of the rotating shaft 18 drives the cam 19 connected to it to rotate. The rotation of the cam 19, through cooperation with the elastic component 5, causes the filter screen 4 on one side to shake continuously. The shaking of the filter screen 4 accelerates the efficiency of the filter screen 4 in filtering raw materials, and at the same time, it can prevent the raw materials from sitting on one side of the filter screen 4 and causing the filter screen 4 to become clogged, thus improving the practicality of the device.

[0025] Furthermore, the connecting mechanism 17 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0026] Furthermore, the elastic component 5 can be a spring or an elastic sheet, etc., which will not be described in detail here.

[0027] The working principle of this utility model is as follows: The raw material to be filtered is fed into one side of the filter plate 6 through the feed inlet. Under the action of gravity, the raw material will pass through the filter plate 6 for filtration. After preliminary filtration, the raw material will drip onto the second filter screen 4 at the bottom. The second filter screen 4 will further filter the raw material. During this process, the dual-axis motor 15 drives the first drive shaft 14 and the second drive shaft 16 connected to it to rotate. The rotation of the first drive shaft 14 drives the driven shaft 7 to rotate through the connecting unit 13. The rotation of the driven shaft 7 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11, under the action of the thread, drives the guide plate 8 connected to it to move downward. The downward movement of the guide plate 8 can drive the pressure plate 12 at one end of the connecting rod 10 to move downward. The downward movement of the pressure plate 12 reduces the volume between the pressure plate 12 and the raw material, thereby increasing the pressure in the space between them. This increased pressure exerts pressure on the raw material, allowing the filter plate 6 to filter the raw material more quickly, thus improving the filtration efficiency. The rotation of the second drive shaft 16 drives the rotating shaft 18 connected to it to rotate through the connecting mechanism 17. The rotation of the rotating shaft 18 drives the cam 19 connected to it to rotate. The rotation of the cam 19, in cooperation with the elastic component 5, causes the filter screen 4 on one side to shake continuously. The shaking of the filter screen 4 accelerates the filtration efficiency of the filter screen 4 on the raw material, while preventing the raw material from remaining still on one side of the filter screen 4 and causing the filter screen 4 to become clogged, thus improving the practicality of the device.
