[0002] Gel pens originated in Japan and are a new type of writing tool that is popular in East Asia. Gel pens can be divided into different types according to the type of pen tip, ink color, structure, etc. You can choose according to your needs. Gel pens have the advantages of both fountain pens and oil-based ballpoint pens. They are comfortable to write with, have low ink viscosity, and add appropriate lubricants. The viscosity of the writing medium is between water-based and oil-based, so it is smoother than ordinary oil-based ballpoint pens. It is an upgraded product of oil-based ballpoint pens. The pen holder of the gel pen is an important component, and it is mass-produced by injection molding during the production process.

[0003] The related technology (publication number CN220261933U) discloses a gel pen barrel processing injection molding device, and the disclosed technical solution is as follows: after the pen barrel is extruded after injection molding, the second motor drives the bevel gear to make the bevel wheel ring drive the friction tube to rotate, and the first gear arranged at the rear end of the bevel gear drives the chain to rotate the second gear, and the second gear rotates the second roller. At the same time, the spring rod squeezes the pen barrel to fix it, allowing the pen barrel to enter the friction tube, and the friction tube grinds the pen barrel to make the surface of the pen barrel smooth, so that the pen barrel can be directly grinded at one time after the injection molding is completed, saving extra time in the grinding process and improving work efficiency.

[0004] In the above disclosed technical solution, it is found that the following problems exist in the related technology: in order to ensure the production efficiency of gel pens, pen holders are usually produced by injection molding in large quantities. After the pen holders are discharged, a large number of pen holders will fall randomly at the receiving area, requiring relevant personnel to sort out the materials one by one, thus affecting the production efficiency of the pen holders. In this regard, we propose a new type of gel pen holder processing injection molding device.

[0033] A gel pen barrel processing injection molding device comprises a processing table 1, an injection molding bin 2 is arranged on the top of the processing table 1, and the injection molding bin 2 is fixedly installed on the upper surface of the processing table 1. The pen barrel is injection-molded inside the injection molding bin 2, so that the molded pen barrel is discharged from the discharge port of the injection molding bin 2. A receiving bin 3 is arranged below the discharge port of the injection molding bin 2, and the receiving bin 3 is installed on the upper surface of the processing table 1. The receiving bin 3 is located below the discharge port of the injection molding bin 2, so that the pen barrel discharged from the injection molding bin 2 will fall on the receiving bin 3, and a vibration component for discharging one by one is arranged between the receiving bin 3 and the processing table 1. A discharge port 11 with an aperture corresponding to the pen barrel is opened on the side of the receiving bin 3. Through the vibration component between the upper surface of the processing table 1 and the bottom of the receiving bin 3, the pen barrels falling into the receiving bin 3 are discharged from the discharge port 11 in sequence, so that the pen barrels are prevented from stacking inside the receiving bin 3, thereby ensuring the smoothness of the discharge process of the pen barrels.

[0034] The top of the processing table 1 is provided with a material drop slope 29 that is connected to the material drop point of the receiving bin 3, and the end of the material drop slope 29 is provided with a collection bin 4. An arc-shaped material drop slope 29 is provided on one side surface of the processing table 1, and the high part of the material drop slope 29 is located below the material outlet of the receiving bin 3. The low part of the material drop slope 29 is connected to the collection bin 4, so that the pen rods discharged from the side outlet of the receiving bin 3 fall into the interior of the collection bin 4 through the arc-shaped material drop slope 29. A material guide assembly for sequentially conveying the pen rods is provided at the joint of the collection bin 4 and the material drop slope 29. The pen rods are sequentially entered into the interior of the collection bin 4 through the material guide assembly, so that the pen rods are automatically sorted, thereby ensuring the neatness of the pen rod collection.

The pen holders slide through the guide plate 16 to the discharge port 11, and are discharged from the discharge port 11 to the outside of the receiving silo 3. When collecting the pen holders discharged from the injection molding silo 2, the pen holders are made to fall inside the receiving silo 3, and then the vibration motor is connected to the power supply, and the receiving silo 3 is vibrated through the elastic member 25 at the bottom of the receiving silo 3. A discharge port 11 connected to the inner cavity is opened on the side of the receiving silo 3 opposite to the blanking slope 29, so that the pen holders are discharged one by one from the discharge port 11 through the vibrating receiving silo, thereby ensuring the smoothness of the pen holder discharge process.

[0041] In addition, the inner cavity of the material collection bin 4 is provided with limit plates 13 for arranging pen holders at an angle in sequence.
