Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printers, and particularly relates to an ink bottle fixing and monitoring mechanism. Background Art

[0002] Food inkjet printers can print personalized patterns or information on the surfaces of foods such as cakes, cookies, mooncakes, etc. by using edible ink. In current food inkjet printing technology, the fixing of the ink bottle and the monitoring of the remaining ink volume in the ink bottle are difficult problems to handle. Unstable fixing of the ink bottle easily leads to ink leakage, affecting the operation of the printer, and insufficient remaining ink volume will cause printing interruption.

[0003] Traditional inkjet printer position adjustment mechanisms, such as an ink bottle installation and fixing structure disclosed in Chinese Patent Publication No. CN218399898U, complete the installation of the ink bottle by inserting the ink bottle into the installation port and the clamping portion being clamped on the elastic lock block. However, it is difficult to monitor the remaining ink volume in the ink bottle, especially for opaque or semi-opaque ink bottles, and it is difficult to visually monitor the remaining ink volume in the ink bottle through external vision. Summary of the Utility Model

[0004] The purpose of the utility model is to propose an ink bottle fixing and monitoring mechanism to solve the problem that it is difficult to monitor the remaining ink volume in the ink bottle in the prior art.

[0029] In this embodiment, the liquid level sensor 5 is a capacitive liquid level sensor. The capacitive liquid level sensor can measure the height of the liquid level in the ink bottle outside the ink bottle and generate an alarm when the ink remaining in the ink bottle is low.

[0030] The pressing assembly 3 includes a first fixing seat 31, a second fixing seat 32, a wrench 33, a first connecting rod 34, a second connecting rod 35, and a pressing plate 36. The first fixing seat 31 and the second fixing seat 32 are fixedly installed on the support assembly 2. The first fixing seat 31 is connected to the wrench 33 through a damping rotating shaft. A through hole 37 is provided on the second fixing seat 32. The second connecting rod 35 is slidably connected in the through hole 37. One end of the first connecting rod 34 is rotatably connected to the wrench 33, and the other end of the first connecting rod 34 is rotatably connected to one end of the second connecting rod 35. The pressing plate 36 is arranged at one end of the second connecting rod 35. The combination of the first fixing seat 31, the wrench 33, the first connecting rod 34, the second connecting rod 35, and the second fixing seat 32 in the pressing assembly 3 forms a mechanical four-bar linkage mechanism. The dead point principle of the four-bar linkage mechanism is used to lock the second connecting rod 35, and the first connecting rod 34 cannot be pushed by using the second connecting rod 35 as a driving member, thereby ensuring the fixing stability of the ink bottle.

[0031] There are several fixing grooves 4, which are evenly distributed in the horizontal direction. There are several pressing assemblies 3 arranged on the support assembly 2, and the pressing assemblies 3 correspond to the fixing grooves 4 one by one.

[0037] Working principle: When fixing the ink bottle, place the ink bottle in the fixing groove 4, pull the wrench 33 to make the pressing plate 36 press and fix the ink bottle tightly. At the same time, the combination of the first fixing seat 31, the wrench 33, the first connecting rod 34, the second connecting rod 35, and the second fixing seat 32 in the pressing assembly 3 forms a mechanical four-bar linkage mechanism. The dead point principle of the four-bar linkage mechanism is used to lock the second connecting rod 35. Taking the second connecting rod 35 as the driving part, it is impossible to push the first connecting rod 34, so as to ensure the fixing stability of the ink bottle. When the ink bottle needs to be taken out, pull the wrench 33, and use the wrench 33 as the driving part to drive the first connecting rod 34 and the second connecting rod 35 to move, so that the ink bottle can be taken out.
