Description

Technical Field

[0001] This utility model relates to the field of ink production technology, specifically to an anti-clogging filling head for ink production. Background Technology

[0002] In the field of ink production, the filling head is a key component for accurately injecting ink into packaging containers. Its anti-clogging performance directly affects production efficiency and product quality. Ink has the characteristics of high viscosity and easy curing, and often contains particulate impurities.

[0003] Existing filling heads are prone to clogging due to ink residue coagulation and improper temperature control during long-term use. This can cause particulate impurities to block the discharge channel, resulting in a decrease in filling accuracy. The equipment needs to be shut down for cleaning, which is inconvenient for daily use. Utility Model Content

[0020] Please see Figure 1-4This utility model provides a technical solution: an anti-clogging filling head for ink production, including a guide cavity 1, with a feed pipe 2 connected to one side of the guide cavity 1. The guide cavity 1 is a cylindrical tube open at both ends. A feed hole is provided through one side of the guide cavity 1. One end of the feed pipe 2 is welded to the feed hole. A top plate 3 is threaded to the top of the guide cavity 1. A bracket 4 is fixedly connected to the outside of the top plate 3. A driver 5 is installed at the top of the top plate 3. A scraper 6 is provided at the bottom of the driver 5. An installation hole is provided through the middle of the top of the top of the top plate 3. A coupling is provided at the bottom of the driver 5. The lower part of the coupling is through... The mounting hole extends to the lower part of the top plate 3. The top plate 3 is connected to the scraper 6 via the driver 5. The scraper 6 consists of two "D"-shaped rods arranged in a cross shape. The scraper 6 is located inside the guide cavity 1, and the outer side of the scraper 6 abuts against the inner wall of the guide cavity 1. The driver 5 is a servo motor of model SM-J100, which drives the scraper 6 to rotate clockwise via a coupling to remove residual ink from the guide cavity 1 and the inner wall of the inner tube 703. An infusion tube assembly 7 is welded to the bottom of the guide cavity 1. The infusion tube assembly 7 includes a housing 701 and an inner tube 703. The outer casing 701 and the inner tube 703 are fitted onto the outer wall of the inner tube 703, forming a gap. The electric heating tape 702 is wound around the outer wall of the inner tube 703 and located within the gap. The infusion tube assembly 7 is cylindrical at both ends. A groove is formed on the inner wall of the outer casing 701. The outer casing 701 and the inner tube 703 are coaxially arranged. The electric heating tape 702 is fitted into the groove on the inner wall of the outer casing 701. The electric heating tape 702 is a constant power mineral-insulated heating cable, model MI-20. The groove on the inner wall of the outer casing 701 is interference-fitted with the electric heating tape 702, and... Thermally conductive silicone filler is used to ensure efficient heat transfer. An armored PT100 temperature sensor is built into one side of the groove in the outer shell 701 and connected to an external PID controller via wires to adjust the output power of the electric heating tape 702 in real time, so that the temperature of the inner wall of the inner tube 703 is maintained in the UV ink activation range of 35-45℃.
