[0028] In addition, the terms "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0029] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "splicing", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] The utility model will be described below in combination with Figures 1 to 5 , a dust leakage prevention sol cylinder, comprising a sol cylinder body 1 and a sol screw rod 2, the sol screw rod 2 is installed at the rear end of the sol cylinder body 1, and the sol screw rod 2 partially extends into the screw rod containing cavity 12 of the sol cylinder body 1, characterized in that:

[0031] Further, a leakage pipe 3 is installed at the rear end of the solenoid barrel 1, and the leakage pipe 3 is in communication with the screw accommodating cavity 12.

[0032] The sealing mechanism 4 is installed between the solenoid screw 2 and the rear end face of the solenoid barrel 1, and is used to seal the gap between the solenoid screw 2 and the rear end face of the solenoid barrel 1.

[0033] The dust-proof solenoid barrel is provided with the leakage pipe 3 and the sealing mechanism 4 at the rear end of the solenoid barrel 1. When the solenoid screw 2 rotates counterclockwise in the screw accommodating cavity 12 of the solenoid barrel 1, the plastic particles enter the thread groove of the solenoid screw 2, and the plastic particles are extruded and rubbed between the screw accommodating cavity 12 and the solenoid screw 2, thereby causing the plastic dust to seep out of the rear end of the solenoid barrel 1. Since the sealing mechanism 4 is installed at the rear end of the solenoid barrel 1, the plastic dust cannot seep out of the rear end of the solenoid barrel 1, but can only be discharged from the leakage pipe 3, thereby achieving centralized recovery of the plastic dust and realizing renewable plastic, which is environmentally friendly and economical.

[0034] Further, as shown in Figure 3 The sealing mechanism 4 includes a sealing ring 41, which is installed between the solenoid screw 2 and the rear end face of the solenoid barrel 1. The sealing ring 41 is installed between the solenoid screw 2 and the rear end face of the solenoid barrel 1, which effectively prevents the plastic dust from seeping out of the rear end of the solenoid barrel 1.

[0035] Further, as shown in Figure 3 The sealing mechanism 4 further includes a wear-resistant ring 42, the inner ring surface of the sealing ring 41 is provided with a wear-resistant ring installation groove 411, the wear-resistant ring 42 is arranged in the wear-resistant ring installation groove 411, and the inner ring surface of the wear-resistant ring 42 is flush with the inner ring surface of the sealing ring 41. The inner ring surface of the sealing ring 41 is provided with the wear-resistant ring 42, which can greatly reduce the wear of the sealing ring 41 by the rotating solenoid screw 2, prolong the service life of the sealing mechanism 4, and improve the reliability of the sealing.

[0036] It should be noted that the wear-resistant ring 42 includes a metal ring body and a high-temperature-resistant layer, and the high-temperature-resistant layer covers the metal ring body. The material of the metal ring body can be a copper body or a stainless steel body, which has the characteristics of wear resistance and firmness. Since the plastic particles are heated and extruded in the screw accommodating cavity 12, the surface temperature of the solenoid screw 2 is high, so the metal ring body needs to be coated with a high-temperature-resistant layer to protect it. The high-temperature-resistant layer can be polytetrafluoroethylene, which has the characteristics of high temperature resistance and low friction coefficient.

[0037] Preferably, as shown in Figure 5As shown, the wear-resistant ring 42 is provided with a notch 421, which is arranged obliquely. Because the plastic particles are heated and extruded in the screw accommodating cavity 12, the surface temperature of the solenoid screw 2 is high, and the wear-resistant ring 42 in contact with it is prone to thermal expansion, thereby affecting the sealing performance. Therefore, the notch 421 is arranged on the wear-resistant ring 42 to offset the deformation of the wear-resistant ring 42 caused by thermal expansion, thereby ensuring that the sealing ring 41 and the wear-resistant ring 42 also have good sealing performance at high temperatures. The oblique arrangement of the notch 421 can better disperse stress and heat.

[0038] Specifically, as shown in the drawings, Figure 4 The side surface of the sealing ring 41 is provided with a mounting screw hole 412, and the sealing ring 41 is connected with the rear end of the solenoid cylinder 1 through the mounting screw hole 412 and the rear end screw thread. The sealing ring 41 is installed on the rear end of the solenoid cylinder 1 through the mounting screw hole 412 and the rear end screw thread. The installation is firm, and the sealing ring 41 can be easily removed for cleaning during daily maintenance.

[0039] In some embodiments, as shown in the drawings, Figure 2 The screw accommodating cavity 12 is provided with a discharge port 13 near the rear end of the solenoid cylinder 1, and one end of the discharge pipe 3 communicates with the discharge port 13. The discharge pipe 3 and the solenoid cylinder 1 are detachably connected by screws, which is firm and can be easily removed for cleaning during daily maintenance. In addition, different diameters of discharge pipes 3 can be configured according to different diameters of solenoid cylinders 1.

[0040] More specifically, as shown in the drawings, Figure 2 The solenoid cylinder 1 is also provided with a discharge port 11, and the front end of the solenoid cylinder 1 is provided with a nozzle. The discharge port 11 and the nozzle both communicate with the screw accommodating cavity 12, and the discharge port 11 is located in front of the discharge port 13.

[0041] During operation, the plastic particles enter the thread groove of the solenoid screw 2, and the plastic particles are heated, extruded and rubbed between the screw accommodating cavity 12 and the solenoid screw 2, and finally sprayed out of the nozzle at the front end of the solenoid cylinder 1. However, during operation, the solenoid screw 2 rotates counterclockwise in the screw accommodating cavity 12 of the solenoid cylinder 1, and part of the plastic dust will seep out of the rear end of the solenoid cylinder 1. Therefore, the discharge port 13 is arranged behind the discharge port 11.

[0042] Further, as shown in the drawings, Figure 1 and 2 It also includes a glue injection head seat 5 and a solvent cylinder nut 6, and the solenoid cylinder 1 is installed on the glue injection head seat 5 through the solvent cylinder nut 6. The glue injection head seat 5 is provided with a discharge pipe 51, and the discharge pipe 51 communicates with the discharge port 11 of the solenoid cylinder 1. The glue injection head seat 5 is used to fix the solenoid cylinder 1, and is provided with a discharge pipe 51 to facilitate discharging.

[0043] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted as limiting the protection scope of the present application in any way. Based on the explanations herein, other specific embodiments of the present application can be conceived by those skilled in the art without creative efforts, and these embodiments will all fall within the protection scope of the present application.
