Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to a device for refilling ink and sealing agent into a pen core. Background Art

[0002] Gel pens have the advantages of simple structure, easy replacement, and smooth writing. They are a popular new type of writing tool. However, the service life of gel pens is very short. Unlike fountain pens, fountain pens can absorb ink repeatedly, while gel pens cannot be used after the ink in the refill is used up, and the refill can only be replaced. This will not only cause environmental pollution and waste of resources, but also increase the cost of using gel pens. According to data, as of 2023, there are currently 289 million students in my country, of which more than 90% of students use gel pens, and various enterprises, institutions and administrative units also have a certain demand for gel pens. Therefore, there is a great demand for gel pens in my country.

[0003] However, there are the following problems in the use of gel pens on the market:

[0004] 1. The materials used to make the refills on the market are polystyrene or modified polystyrene, which cannot degrade on their own. The refills also contain volatile excess grease and other pollutants. Therefore, the discarding of refills causes certain pollution to the environment, but the cost of recycling refills is higher than the cost of purchasing raw materials, which hinders the development of gel pen recycling.

[0005] 2. In addition to recycling gel pens, the refill can be refilled with ink using an ink filling mechanism to achieve the effect of reuse. However, the existing ink filling mechanisms have limited application scope and will cause some sealants to remain on the wall, which may cause subsequent writing to be unsmooth. In order to solve the above problems, we propose a new refill refilling and sealant filling device. Summary of the invention

[0006] In order to solve the above technical problems, the utility model provides a device for refilling ink and sealing agent of a pen core, comprising a pen holder clamping mechanism, a steering mechanism, a pen head disassembling mechanism, an ink filling mechanism and a sealing agent replenishing mechanism.

[0007] Preferably, the pen holder clamping mechanism includes a refill slot and a threaded ring, the threaded ring and the refill slot are connected by threads, the threaded ring is rotated clockwise to move the threaded ring upward, and the refill is placed in the refill slot. The threaded ring is rotated counterclockwise to fix the refill and the refill slot relatively.

[0008] Preferably: the steering mechanism includes a refill slot, a first connecting piece, a second clamping piece, and a pen clamp base. The refill slot, the first connecting piece, and the second clamping piece are fixed by bolts. The second clamping piece can be rotated 90° relative to the pen clamp base to achieve steering.

[0009] Preferably: the mechanism for disassembling and assembling the pen tip includes an upper clamp, a second connecting member, a linkage member, a nut, a rod, and a lower clamp. The linkage member is fixedly connected to the rod. The upper clamp and the linkage member, the upper clamp and the lower clamp, and the linkage member and the lower clamp are connected through a column to achieve clearance fit. When the rod moves upward or downward, the linkage member limits the movement range of the rod. The linkage member drives the upper clamp to move to achieve clamping and loosening of the pen tip, and the nut adjusts the tightness.

[0010] Preferably, the ink injection mechanism comprises a second pipe, a second spring, a second steel ball, an ink storage box, a second push rod, a second storage tube, and a second piston. The second electric push rod is fixedly connected to the second piston, the second piston is sleeved in the second storage tube, the second piston and the second storage tube are interference fit, and the second pipe is fixedly connected to the ink injection needle tube. The second electric push rod performs a reciprocating motion to complete one ink injection.

[0011] Preferably: the sealant replenishing mechanism includes a first pipe fitting, a first spring, a first steel ball, a sealant storage box, a first push rod, a first storage tube, and a first piston. The first electric push rod and the first piston are fixedly connected, the first piston is sleeved in the first storage tube, the first piston and the first storage tube are interference fit, the first pipe fitting and the sealant injection needle are fixedly connected, and the first electric push rod performs a reciprocating motion to complete a sealant injection.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model has a simple structure and is easy to operate. The design of the refill ink and sealant refilling device not only reduces the waste of the refill, but also ensures the smooth writing of the refill. The recycling of the refill is also beneficial to environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS
