Description

Technical Field

[0001] This utility model relates to the technical field of ink production equipment, specifically to a storage tank for ink production. Background Technology

[0002] In the ink manufacturing industry, storage tanks are crucial equipment for storing ink, and their performance and design directly affect ink quality and production efficiency. Gravure inks, as a commonly used printing ink, require specialized storage tanks for storage and subsequent processing during production. With the continuous development of ink production technology, the functional and performance requirements for storage tanks are also increasing. Currently, while ink production storage tanks on the market meet the basic needs of ink storage and dispensing to a certain extent, some problems still urgently need to be addressed in actual use.

[0003] In the prior art, such as the Chinese patent (publication number: CN202223413512.X) that discloses a storage tank for gravure ink production, the storage tank is equipped with a discharge mechanism. An electric push rod pushes a push plate and a sealing gasket to move to avoid ink residue. The output shaft of the electric push rod needs to penetrate through the storage tank wall. Under the influence of frequent use of the storage tank, vibration, and ink corrosion, the sealing performance of the sealing gasket may gradually decrease, causing ink to leak from the gap between the output end and the storage tank body, resulting in ink waste and increased production costs. Utility Model Content

[0004] The purpose of this invention is to provide a storage tank for ink production, which solves the problem of ink leakage by scraping the ink off the inner wall of the storage chamber using a scraper and a counterweight.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a storage tank for ink production, including a storage tank body, a scraper and a support. The storage tank body has a storage cavity, the scraper contacts the inner wall of the storage cavity, a counterweight is installed on the outer surface of the scraper, a guide rail is provided in the storage tank body, the guide rail is connected to the storage cavity, and the counterweight slides in the guide rail.

[0007] Furthermore, there are four guide rails, which are located around the storage cavity, and each of the four guide rails has a wedge-shaped block installed on its top.

[0008] Furthermore, a guide strip is installed at the bottom of the scraper. Both the scraper and the guide strip are circular, and the bottom of the guide strip has a chamfer.

[0009] Furthermore, the scraper is provided with guide holes, and the guide strip is provided with through holes at the corresponding positions of the guide holes. A vertical pipe is provided inside the guide holes, and a one-way valve is provided on the vertical pipe.

[0010] Furthermore, the support has a perforation, and a rotating shaft fits inside the perforation. The end of the rotating shaft is connected to the middle of the storage tank body.

[0011] Furthermore, a drive source is mounted on the top of the bracket, and the output end of the drive source is connected to the rotating shaft.

[0012] This utility model has the following beneficial effects:

[0013] This invention uses a scraper and a counterweight to scrape away ink from the inner wall of the storage chamber. When the storage tank is tilted at a certain angle to pour out the ink, the counterweight slides down the guide rail, driving the annular scraper to scrape away the residual ink on the inner wall of the storage tank. When the storage tank returns to its upright position, the counterweight drives the scraper back to its original position. This avoids the sealing problems and increased costs associated with using an electric push rod. The gravity-driven method has a simple structure, reliable operation, and reduces the failure rate and maintenance costs of the equipment.

[0014] This invention uses guide strips and vertical pipes to guide ink out from behind the scraper. Guide holes and vertical pipes are installed inside the scraper. When ink accumulates behind the guide strips, it can be discharged through the vertical pipes using its own weight and the pressure generated by the tilt of the storage tank. This allows the ink to flow out more smoothly, avoiding the problem of poor flow caused by ink accumulation behind the scraper. This greatly improves the ink discharge efficiency, reduces the residual time of ink in the storage tank, ensures that the ink can only flow out in the pouring direction, prevents backflow or leakage, and improves pouring efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a storage tank for ink production, including a storage tank body 1, a scraper 4, and a support 2. The support 2 has a through hole, and a rotating shaft 202 is fitted inside the through hole. The end of the rotating shaft 202 is connected to the middle of the storage tank body 1. A drive source 201 is installed on the top of the support 2, and the output end of the drive source 201 is connected to the rotating shaft 202. By starting the drive source 201, the rotating shaft 202 is rotated, thereby causing the storage tank body 1 to tilt at a certain angle to discharge ink. A storage cavity 101 is formed inside the storage tank body 1. The scraper 4 contacts the inner wall of the storage cavity 101. A counterweight 3 is installed on the outer surface of the scraper 4. A guide rail 102 is formed inside the storage tank body 1, and the guide rail 102 is connected to the storage cavity 101. The counterweight 3 is slidably fitted inside the guide rail 102. There are four guide rails 102. Around the storage chamber 101, wedge blocks 6 are installed on the top of the four guide rails 102. The wedge blocks 6 facilitate the discharge of ink pushed by the counterweights 3 in the guide rails 102, preventing it from accumulating in the guide rails 102. When the ink in the storage tank body 1 is poured out from the outlet, the drive source 201 is activated to drive the rotating shaft 202 to rotate, causing the storage tank body 1 to tilt at a certain angle to discharge the ink. At this time, due to gravity, the four counterweights 3 slide along the corresponding guide rails 102 toward the outlet of the storage tank body 1, thereby driving the scraper 4 to scrape out the residual ink on the inner wall of the storage chamber 101. Since the storage tank body 1 is tilted, the four counterweights 3 scrape the ink in the guide rails 102 until the counterweights 3 touch the bottom of the wedge blocks 6. At this time, the ink in the guide rails 102 is discharged from the storage chamber 101 to the outlet through the guidance of the wedge blocks 6.

[0024] A guide strip 5 is installed at the bottom of the scraper 4. Both the scraper 4 and the guide strip 5 are circular. The bottom of the guide strip 5 is chamfered, which can cause the ink to flow back to the side near the storage chamber 101, making it easier to be discharged from the through hole 501. A guide hole 401 is provided on the scraper 4. A through hole 501 is provided at the corresponding position of the guide strip 5 and the guide hole 401. A vertical pipe 7 is provided in the guide hole 401. A one-way valve 8 is provided on the vertical pipe 7. Since the storage tank body 1 is in an inclined state, after the scraper 4 scrapes the ink in the storage chamber 101, the ink behind the scraper 4 continues to flow towards the outlet. At this time, the ink gathers towards the inner wall of the storage chamber 101 through the chamfer of the guide strip 5, and then flows through the through hole 501 and the vertical pipe 7 to be discharged from the outlet of the storage tank body 1. The one-way valve 8 can prevent the ink from flowing back into the rear of the scraper 4 when the scraper 4 scrapes the inner wall of the storage chamber 101.
