Abstract
Description
Technical Field
[0001] This utility model belongs to the field of screen printing machine technology, specifically relating to an ink injection mechanism for quick-drying ink used in screen printing. Background Technology
[0002] In the field of screen printing, quick-drying inks are widely used in various screen printing operations due to their fast drying speed and high production efficiency. After the ink in the screen printing machine is used up, it needs to be refilled through the ink filling mechanism to avoid affecting the normal operation of the screen printing machine.
[0003] Existing, common ink filling mechanisms for screen printing machines mainly consist of an ink tank, a delivery pipe, and an ink nozzle. Ink is dispensed from the screen printing machine's ink tank and the ink nozzle is inserted into it. While this mechanism meets the basic ink filling requirements of screen printing operations to a certain extent, delivering fast-drying ink from the storage device to the ink tank, a certain amount of ink remains in the delivery pipe after ink delivery. This is because the ink cannot be completely emptied from the pipe after the filling operation. Since fast-drying ink has a certain viscosity, it easily adheres to the inner wall of the pipe, resulting in some ink residue. This residual ink drips down the pipe into the ink filling area, affecting the overall cleanliness of the work area and causing waste. Utility Model Content
[0004] The purpose of this invention is to provide an ink injection mechanism for quick-drying ink used in screen printing, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an ink dispensing mechanism for quick-drying ink used in screen printing, comprising:
[0006] A frame, the top of which is connected to a chassis and the chassis contains an oil storage tank for oil filling;
[0007] The ink injection pipe is connected to the center of the bottom of the oil storage tank and is used to inject ink into the screen printing ink tank. The ink injection pipe is equipped with a sealing component for sealing the ink injection pipe after ink injection is completed. The sealing component includes a sealing block and a guide rod. The sealing block is located inside the ink injection pipe and is used to seal the oil outlet inside the ink injection pipe. Several sets of guide rods are provided and are respectively connected to the bottom of the sealing block. One end of the guide rod slides through a groove provided inside the ink injection pipe.
[0008] Preferably, a sealing ring is provided at the penetration point between the guide rod and the oil injection pipe, and a spring is fitted on the surface of the guide rod, with both ends of the spring connected to the oil injection pipe and the guide rod respectively.
[0009] Preferably, an annular inclined block is connected inside the oil outlet, and several push rods are connected to the bottom of the sealing block, with the other end of the push rods sliding through the annular inclined block.
[0010] Preferably, a sealing gasket is connected to the bottom of the sealing block.
[0011] Preferably, the top of the screen printing ink tank is connected to an oil inlet pipe, which is inserted into the oil outlet of the oil filling pipe for oil filling.
[0012] Preferably, the top of the casing is provided with a first cylinder and the piston rod of the first cylinder moves through the casing and is connected to the oil tank. Two sets of sliding rods are connected inside the casing, and the two ends of the oil tank are slidably sleeved on the surface of the sliding rods by sliders.
[0013] Preferably, the top of the oil storage tank is connected to an oil replenishment pipe.
[0014] Preferably, the top of the frame is connected to two sets of fixed seats and a second cylinder is provided in the fixed seats, and the piston rod of the second cylinder is connected to a clamping block.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) The oil injection pipe is equipped with a sealing component, including a sealing block, a guide rod and other components. After the oil injection is completed, the sealing block can effectively seal the oil outlet of the oil injection pipe to prevent the ink remaining in the pipe from dripping into the work area. This not only keeps the work area clean, but also reduces ink waste and lowers production costs.
[0017] (2) The fixed seat connected to the top of the frame is equipped with a second cylinder. The clamping block connected to its piston rod can accurately fix the screen printing ink tank during the ink filling process, ensuring that the screen printing ink tank will not shake or shift during ink filling, ensuring the smooth progress of the ink filling operation, improving the accuracy and stability of ink filling, and avoiding the situation of ink spillage or poor ink filling caused by the shaking of the ink tank.
[0018] (3) The annular inclined block connected inside the oil outlet guides the ink, allowing the ink flowing from the oil injection pipe to flow more smoothly into the oil inlet pipe of the screen printing ink tank. This optimizes the ink flow path, reduces ink accumulation and resistance at the oil outlet, improves the oil injection efficiency, and prevents ink from flowing out from the gap between the oil inlet pipe and the inner wall of the oil injection pipe.
[0019] (4) The sealing gasket connected to the bottom of the sealing block further enhances the sealing effect on the oil outlet. The sealing gasket has good flexibility and sealing performance, which can better fill the tiny gap between the sealing block and the oil outlet, prevent ink leakage, and effectively prevent ink dripping even when the equipment is vibrating or affected by external forces.

[0025] 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.
[0026] This utility model provides, for example Figure 1-4 The ink dispensing mechanism for quick-drying screen printing ink shown includes:
[0027] A frame 1, the top of which is connected to a housing 2 and the housing 2 is equipped with an oil storage tank 3 for oil filling;
[0028] The ink injection pipe 4 is connected to the center of the bottom of the oil storage tank 3 and is used to inject ink into the screen printing ink tank 21. The ink injection pipe 4 is provided with a sealing assembly for sealing the ink injection pipe 4 after the ink injection is completed. The sealing assembly includes a sealing block 5 and a guide rod 6. The sealing block 5 is located inside the ink injection pipe 4 and is used to seal the oil outlet 7 inside the ink injection pipe 4. Several sets of guide rods 6 are provided and are respectively connected to the bottom of the sealing block 5. One end of the guide rod 6 slides through the groove 8 provided inside the ink injection pipe 4.
[0029] A sealing ring 9 is provided at the penetration point between the guide rod 6 and the oil injection pipe 4. A spring 10 is fitted on the surface of the guide rod 6, and the two ends of the spring 10 are respectively connected to the oil injection pipe 4 and the guide rod 6.
[0030] An annular inclined block 11 is connected inside the oil outlet 7. Several push rods 12 are connected to the bottom of the sealing block 5, and the other end of the push rod 12 slides through the annular inclined block 11. The annular inclined block 11 facilitates the flow of ink into the oil inlet pipe 14.
[0031] The bottom of the sealing block 5 is connected to a sealing gasket 13, and the sealing block 5 can fit tightly against the oil outlet 7 to seal the oil outlet 7.
[0032] The top of the screen printing ink tank 21 is connected to an oil inlet pipe 14, which is inserted into the oil outlet 7 inside the oil filling pipe 4 for oil filling.
[0033] The top of the casing 2 is provided with a first cylinder 15, and the piston rod of the first cylinder 15 moves through the casing 2 and is connected to the oil tank 3. Two sets of sliding rods 16 are connected inside the casing 2. The two ends of the oil tank 3 are slidably sleeved on the surface of the sliding rods 16 by sliders. The sliding rods 16 guide the movement direction of the oil tank 3, which can enhance the stability of the movement of the oil tank 3.
[0034] The top of the oil storage tank 3 is connected to an oil replenishment pipe 17, through which ink that needs to be injected into the screen printing oil tank 21 can be replenished into the oil storage tank 3.
[0035] The top of the frame 1 is connected to two sets of fixed seats 18, and a second cylinder 19 is provided in the fixed seat 18. The piston rod of the second cylinder 19 is connected to a clamping block 20. When the piston rod of the second cylinder 19 extends, it can drive the clamping block 20 to move and accurately fix the screen printing ink tank 21 in a suitable position.
[0036] The ink filling mechanism for the quick-drying ink used in screen printing operates as follows: When the screen printing ink tank 21 is removed from the screen printing machine and placed between two sets of clamping blocks 20 on the transport frame 1, the intelligent control box on the frame 1 controls the second cylinder 19 to start. The piston rod of the second cylinder 19 extends, driving the clamping blocks 20 to move and precisely fix the screen printing ink tank 21 in a suitable position. At the same time, the intelligent control box controls the first cylinder 15 to start. The piston rod of the first cylinder 15 extends downward, pushing the ink reservoir 3 to move downward along the slide bar 16. During the movement, the proximity sensor (not shown in the attached figure) on the ink reservoir 3 monitors the relative position of the ink reservoir 3 and the screen printing ink tank 21. The intelligent control box adjusts the action of the first cylinder 15 in real time according to the feedback information, so that the oil outlet 7 of the ink filling pipe 4 is accurately aligned with the oil inlet pipe 14 on the top of the screen printing ink tank 21 and the oil inlet pipe 14 is inserted into the oil outlet 7.
[0037] After the oil inlet pipe 14 is inserted into the oil outlet 7, under the continuous action of the first cylinder 15, the oil inlet pipe 14 pushes the push rod 12 upward, the push rod 12 pushes the sealing block 5 upward and stretches the spring 10, thereby causing the sealing block 5 to disengage from the oil outlet 7. Then, the intelligent control box controls the first cylinder 15 to stop working, and the intelligent control box starts the oil injection process according to the preset oil injection parameters. The quick-drying ink in the oil storage tank 3 flows to the oil outlet 7 through the oil injection pipe 4 under its own gravity or pressure. Since the oil outlet 7 is connected to the annular inclined block 11, the ink is guided by the inclined block when passing through the annular inclined block 11 and flows into the oil inlet pipe 14 to inject oil into the screen printing oil tank 21.
[0038] Once the preset oil filling capacity is reached, the piston rod of the first cylinder 15 is retracted upwards by the intelligent control box, causing the oil tank 3 to move upwards. The oil filling pipe 4 separates from the oil inlet pipe 14 of the screen printing oil tank 21. During the upward movement of the oil tank 3, the oil inlet pipe 14 is pulled out from the oil outlet 7. During the process of pulling out the oil inlet pipe 14, the ink remaining in the oil outlet 7 can continue to flow into the oil inlet pipe 14 until the oil outlet 7 is sealed. As the oil inlet pipe 14 is pulled out, it is no longer pushed by the push rod 12. Then the spring 10 rebounds, which in turn causes the sealing block 5 to move downwards, making the sealing block 5 fit more tightly against the oil outlet 7 and seal the oil outlet 7. The sealing gasket 13 further enhances the sealing effect and prevents the ink remaining in the oil filling pipe 4 from dripping.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
