Description

Technical Field

[0001] This invention relates to the field of printing technology for filter cartridge processing, specifically to a printing device for filter cartridge processing and its usage method. Background Technology

[0002] With urbanization, high-rise buildings require secondary water supply. Since water tanks are cleaned periodically, the water in high-rise residents' homes contains impurities. Some residents choose to use water purification devices, and the most important component of these devices is the filter cartridge. During the manufacturing process, the filter cartridge requires a printing process on its upper part. However, some existing printing devices for filter cartridges still have some shortcomings in use, such as:

[0003] In some existing filter core processing printing devices, the printing block and the dyeing block need to be pushed by different automatic telescopic rods during the printing operation, so that the printing block can be dyed by the dyeing block. However, when pushing with different sets of automatic telescopic rods, the filter core needs to be clamped first, which increases the total printing stroke of the entire device. Furthermore, when clamping the filter core, since the conveyor belt is in the conveying state, the filter core is easily tilted during clamping, which causes the printing operation of the entire device to deviate. Therefore, the present invention proposes a printing device for filter core processing to solve the above problems. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and the title of the invention. Such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problems existing in the printing equipment for processing filter cartridges, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a printing device for processing filter cores, comprising a fixed frame, a support platform bolted to the upper surface of the fixed frame, an automatic telescopic rod bolted to the lower surface of the support platform, a printing table bolted to the inner surface of the support platform, a support rod bolted to the upper surface of the fixed frame, and a connecting rod provided on the outer surface of the support rod.

[0007] In a preferred embodiment of the printing device for processing filter elements according to the present invention, a rotating block is rotatably connected to the inner surface of the fixed frame, a transmission belt is provided on the outer surface of the rotating block, a filter element body is provided on the upper surface of the transmission belt, a driving wheel is rotatably connected to the inner side of the fixed frame, and a driven wheel is rotatably connected to the inner side of the fixed frame.

[0008] Furthermore, the rotation of the rotating wheel drives the transmission belt to rotate continuously, thereby continuously conveying the filter element body. This enables the entire device to operate in an assembly line manner. Moreover, the rotation of the drive wheel and the driven wheel eliminates the need for multiple sets of drive equipment, which not only reduces the manufacturing cost of the entire device but also reduces the stroke of the entire device when printing on the filter element body, thereby improving the printing efficiency of the entire device on the filter element body.

[0009] In a preferred embodiment of the printing device for filter core processing according to the present invention, the outer surface of the automatic telescopic rod is engaged with a locking block, the outer surface of the locking block is fixedly connected with a connecting line, the outer surface of the connecting line is in contact with the passive wheel, the outer surface of the connecting line is in contact with the outer surface of the active wheel, and the lower end of the automatic telescopic rod is bolted to a printing block.

[0010] Furthermore, by extending the automatic telescopic rod, the locking block moves downward, and the connecting line is pulled, which in turn moves the support block upward. This allows the support block to lift the filter element, preventing vibration during the printing process and ensuring the printing completion of the entire device, thus reducing the occurrence of defective products.

[0011] As a preferred embodiment of the printing device for filter core processing according to the present invention, wherein: a limiting groove is formed on the inner surface of the printing table, the limiting groove is centrally symmetrical about the central axis of the printing table, and a sliding block is slidably connected inside the limiting groove;

[0012] Furthermore, by setting the limiting groove, the sliding block can slide, which in turn can drive the dyeing table to move, so that the dyeing table will not affect the printing of the printing block, thus enabling the entire device to work stably.

[0013] As a preferred embodiment of the printing device for filter core processing according to the present invention, wherein: an adjusting block is rotatably connected to the outer surface of the sliding block, a toggle block is torsionally rotatably connected to the right outer surface of the sliding block, the toggle block is in contact with the lower surface of the dyeing table, the dyeing table forms a sliding structure with the printing table through a limiting groove, and a connecting rope is fixedly connected to the lower surface of the dyeing table.

[0014] Furthermore, by adjusting the direction of the connecting rope using the adjusting block, the connecting rope drives the dyeing table to move downwards and horizontally, thus allowing the dyeing table to move without affecting the printing operation of the entire device. At the same time, by deforming the adjusting block itself, the adjusting block can lift the dyeing table, thereby ensuring that the dyeing table can continuously supply dye, making the dyeing operation of the entire device more stable and preventing unclear printing.

[0015] As a preferred embodiment of the printing device for filter core processing according to the present invention, the connecting rope is in contact with the outer surface of the adjusting block, the sliding block forms a sliding structure with the printing table through the limiting groove, a return spring is fixedly connected to the left side surface of the sliding block by bolts, the end of the return spring is fixedly connected to the limiting groove by bolts, and the sliding block forms an elastic structure with the printing table through the return spring.

[0016] Furthermore, by pulling the connecting rope, the sliding block slides inside the limiting groove, thereby squeezing the return spring. This allows the dyeing table to return to its initial position under the deformation of the return spring, ensuring that the dyeing table can continuously supply dye and guaranteeing that the entire device can effectively perform printing operations.

[0017] As a preferred embodiment of the printing device for processing filter cores according to the present invention, a cleaning block is bolted to the upper part of the outer surface of the connecting rod, a connecting groove is provided on the outer surface of the connecting rod, the connecting groove and the support block form a sliding structure, a clamping block is bolted to the outer surface of the support block, the connecting rod and the support rod form a rotating structure, and a torsion spring is bolted to the inside of the connecting rod.

[0018] Furthermore, by rotating the connecting rod, the cleaning block cleans the upper surface of the filter element, thereby reducing the amount of debris on the upper part of the filter element and ensuring the printing efficiency of the entire device. Moreover, by deforming the torsion spring, the connecting rod can return to its initial position after disengaging from the filter element, so that the entire device can continuously process the filter element.

[0019] In a preferred embodiment of the printing device for filter core processing according to the present invention, the connection between the end of the torsion spring and the support rod is a bolt-fixed connection, and the support rod is centrally symmetrical about the central axis of the fixing frame.

[0020] Furthermore, the deformation of the torsion spring allows the connecting rod to forcefully clamp the filter element while returning to its initial position, enabling the entire device to operate on an assembly line and thus improving the printing capacity of the entire device.

[0021] A method of using the above-described printing apparatus for processing filter cartridges, the method comprising the following steps:

[0022] S1: When it is necessary to print on the filter element body, place the filter element body on the transmission belt. The servo motor on the back of the fixed frame drives the rotating block to rotate, and the rotating block drives the transmission belt to transport the filter element body.

[0023] S2: When the filter element body touches the clamping block, the cleaning block cleans the upper surface of the filter element body. The clamping block drives the connecting rod to rotate on the support rod. At this time, the connecting rod winds up the connecting line. The connecting line drives the drive wheel to rotate. The shaft end of the drive wheel winds up the connecting rope. The connecting rope pulls the dyeing table. The dyeing table slides inside the limiting groove. At the same time, the dyeing table squeezes the agitator block. The agitator block rotates on the sliding block to a horizontal state.

[0024] S3: When the filter element body is rotating by pushing the connecting rod, the connecting rope pulls the dyeing table down and then slides horizontally inside the limiting groove, so that the dyeing table is disengaged from the printing block. Then the automatic telescopic rod is activated, and the automatic telescopic rod pushes the printing block to contact the upper surface of the filter element body for printing.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This printing device for filter core processing uses a drive wheel and a driven wheel. When the filter core body contacts the clamping block, the cleaning block cleans the upper surface of the filter core body, thereby reducing the interference of debris during printing and ensuring that the filter core body can be printed smoothly. The clamping block drives the connecting rod to rotate on the support rod. At this time, the connecting rod winds up the connecting line, which drives the drive wheel to rotate. The shaft end of the drive wheel winds up the connecting rope, thereby pulling the connecting rope onto the dyeing table and causing the dyeing table to slide inside the limiting groove. At the same time, the dyeing table squeezes the actuating block, which rotates on the sliding block to a horizontal state. Thus, when the entire device clamps the filter core body, it can separate the dyeing table from the printing block, thereby shortening the processing stroke of the entire device and improving the processing efficiency of the entire device.

[0027] 2. This printing device for filter core processing, through the setting of a connecting line and a support block, and the downward extension of the automatic telescopic rod, causes the automatic telescopic rod to pull the connecting line, thereby moving the connecting line upward. This, in turn, causes the connecting line to drive the support block upward, which in turn drives the clamping block upward. This allows the clamping block to clamp the filter core body upward, thus preventing vibration of the filter core body during printing during continuous operation of the transmission belt. This ensures that the entire device can effectively print on the filter core body, improves the printing accuracy of the entire device, and reduces the defect rate of the printed filter core body.

[0028] 3. The printing device for filter core processing uses a reset spring and a toggle block. The deformation of the reset spring allows the sliding block to push the dyeing table to the vertical position of the limiting groove. At the same time, the toggle block pushes the dyeing table upward inside the limiting groove under the action of the torsion spring inside the toggle block to restore its deformation. This allows the dyeing table to contact the dyeing block and provide dye to the dyeing block, thus ensuring the printing quality of the filter core body of the entire device.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0039] Example

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] like Figure 1-6 As shown, a printing device for processing filter cartridges includes a fixed frame 1. A support platform 2 is bolted to the upper surface of the fixed frame 1, and an automatic telescopic rod 3 is bolted to the lower surface of the support platform 2. A printing table 4 is bolted to the inner surface of the support platform 2. A support rod 6 is bolted to the upper surface of the fixed frame 1, and a connecting rod 5 is provided on the outer surface of the support rod 6. By moving the filter cartridge on the fixed frame 1, the connecting rod 5 rotates on the support rod 6. This rotation of the connecting rod 5 clamps the filter cartridge and cleans its upper surface, thus ensuring that the upper surface of the filter cartridge remains clean. This reduces the occurrence of defects in filter core printing. At the same time, the rotation of the connecting rod 5 can drive the printing table 4 to move up and down and translate, so that the printing table 4 will not affect the movement of the automatic telescopic rod 3. This eliminates the need for multiple sets of automatic telescopic rods 3 to work together, thereby reducing the total printing stroke of the entire device and improving the printing efficiency of the entire device. Furthermore, by extending the automatic telescopic rod 3, the connecting rod 5 can lift the filter core when clamping it, so that the filter core will not vibrate during the printing operation, thus ensuring the stability of the filter core printing.

[0042] In this embodiment, a rotating block 101 is rotatably connected to the inner surface of the fixed frame 1, and a transmission belt 102 is provided on the outer surface of the rotating block. A filter element body 104 is provided on the upper surface of the transmission belt 102. A drive wheel 103 is rotatably connected to the inner side of the fixed frame 1, and a driven wheel 105 is rotatably connected to the inner side of the fixed frame 1. By rotating the rotating wheel 101, the transmission belt 102 can be driven to rotate continuously, so that the filter element body 104 can be continuously conveyed. This allows the entire device to perform assembly line operations. Furthermore, by rotating the drive wheel 103 and the driven wheel 105, the entire device does not require multiple sets of drive equipment, which not only reduces the manufacturing cost of the entire device but also reduces the stroke of the entire device when printing on the filter element body 104, thereby improving the printing efficiency of the entire device on the filter element body 104.

[0043] In this embodiment, a locking block 301 is engaged with the outer surface of the automatic telescopic rod 3, and a connecting line 302 is fixedly connected to the outer surface of the locking block 301. The outer surface of the connecting line 302 is in contact with the passive wheel 105 and the outer surface of the active wheel 103. A printing block 303 is bolted to the lower end of the automatic telescopic rod 3. The connection between the end of the connecting line 302 and the support block 504 is fixed. By extending the automatic telescopic rod 3, the locking block 301 moves downward, and the connecting line 302 is pulled, which in turn causes the support block 504 to move upward. This allows the support block 504 to lift the filter element, thus preventing vibration of the filter element during printing. This ensures the printing completion of the entire device and reduces the occurrence of defective products.

[0044] In this embodiment, a limiting groove 401 is provided on the inner surface of the printing table 4. The limiting groove 401 is centrally symmetrical about the central axis of the printing table 4. A sliding block 404 is slidably connected inside the limiting groove 401. By setting the limiting groove 401, the sliding block 404 can slide, thereby driving the dyeing table 402 to move. This ensures that the dyeing table 402 will not affect the printing of the printing block 303, and thus the entire device can work stably.

[0045] In this embodiment, an adjusting block 407 is rotatably connected to the outer surface of the sliding block 404, and a toggle block 403 is torsionally rotatably connected to the right outer surface of the sliding block 404. The toggle block 403 contacts the lower surface of the dyeing table 402. The dyeing table 402 forms a sliding structure with the printing table 4 through the limiting groove 401. A connecting rope 406 is fixedly connected to the lower surface of the dyeing table 402. By adjusting the direction of the connecting rope 406 through the adjusting block 407, the connecting rope 406 drives the dyeing table 402 to move downward and horizontally, so that the dyeing table 402 can move without affecting the printing operation of the entire device. At the same time, by the deformation of the toggle block 403 itself, the toggle block 403 can lift the dyeing table 402, thereby ensuring that the dyeing table 402 can continuously provide dye, thus making the dyeing operation of the entire device more stable and preventing the printing from being unclear.

[0046] In this embodiment, the connecting rope 406 is attached to the outer surface of the adjusting block 407. The sliding block 404 forms a sliding structure with the printing table 4 through the limiting groove 401. A return spring 405 is bolted to the left side surface of the sliding block 404. The end of the return spring 405 is connected to the limiting groove 401 by bolts. The sliding block 404 forms an elastic structure with the printing table 4 through the return spring 405. By pulling the connecting rope 406, the sliding block 404 slides inside the limiting groove 401, thereby squeezing the return spring 405. This allows the dyeing table 402 to return to its initial position under the deformation of the return spring 405, thus enabling the dyeing table 402 to continuously provide dye and ensuring that the entire device can effectively perform printing operations.

[0047] In this embodiment, a cleaning block 501 is bolted to the upper part of the outer surface of the connecting rod 5. A connecting groove 505 is formed on the outer surface of the connecting rod 5. The connecting groove 505 and the support block 504 form a sliding structure. A clamping block 502 is bolted to the outer surface of the support block 504. The connecting rod 5 and the support rod 6 form a rotating structure. A torsion spring 503 is bolted to the inside of the connecting rod 5. By rotating the connecting rod 5, the cleaning block 501 cleans the upper surface of the filter element, thereby reducing the amount of debris on the upper part of the filter element and ensuring the printing efficiency of the entire device. Furthermore, by deforming the torsion spring 503, the connecting rod 5 can return to its initial position after disengaging from the filter element, so that the entire device can continuously process the filter element.

[0048] In this embodiment, the connection between the end of the torsion spring 503 and the support rod 6 is a bolt-fixed connection. The support rod 6 is centrally symmetrical about the central axis of the fixing frame 1. Through the deformation of the torsion spring 503, the connecting rod 5 can forcefully clamp the filter core and return to the initial position, thereby enabling the entire device to achieve assembly line operation and improving the printing capacity of the entire device.

[0049] It should be noted that the present invention is a printing device for processing filter cores. When it is necessary to perform printing operation on the filter core body 104, the filter core body 104 is placed on the transmission belt 102. The servo motor on the rear side of the fixed frame 1 drives the rotating block 101 to rotate, and the rotating block 101 drives the transmission belt 102 to transport the filter core body 104.

[0050] When the filter element body 104 touches the clamping block 502, the cleaning block 501 cleans the upper surface of the filter element body 104. The clamping block 502 drives the connecting rod 5 to rotate on the support rod 6. At this time, the connecting rod 5 winds up the connecting line 302. The connecting line 302 drives the drive wheel 103 to rotate. The shaft end of the drive wheel 103 winds up the connecting rope 406. The connecting rope 406 pulls the dyeing table 402. The dyeing table 402 slides inside the limiting groove 401. At the same time, the dyeing table 402 squeezes the agitator 403. The agitator 403 rotates on the sliding block 404 to a horizontal state, so that the dyeing table 402 will not block the automatic telescopic rod 3 from driving the dyeing block 303 to move downward.

[0051] When the filter core body 104 pushes the connecting rod 5 to rotate, the connecting rope 406 pulls the dyeing table 402 down, and then slides horizontally inside the limiting groove 401, so that the dyeing table 402 disengages from the printing block 303. Then, the automatic telescopic rod 3 is activated, and the automatic telescopic rod 3 pushes the printing block 303 to contact the upper surface of the filter core body 104 for printing. When the automatic telescopic rod 3 pushes the printing block 303 downward, it drives the locking block 301 downward, thereby pulling the connecting line 302, which in turn pulls the support block 504 to slide inside the connecting groove 505, so that the clamping block 502 lifts the filter core body 104, reducing the impact of the transmission belt 102 on the printing.

[0052] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
