Description

Technical Field

[0001] The utility model provides a quantitative feeding structure for PE material processing, belonging to the technical field of PE material processing. Background Art

[0002] When processing PE materials, hot melt equipment is first used to melt plastic particles into a processable flow state, and then the product is processed by extrusion, injection molding, etc. Although the molten PE material is already in a processable state, further processing steps are often required according to specific production processes and requirements, such as adding color, additives or other auxiliary ingredients to the molten PE material to meet specific product requirements or improve material performance.

[0003] When adding auxiliary materials to molten PE materials for mixing, PE materials are often added to the mixing barrel through a feed pipe. To ensure the mixing effect, PE materials are often added to the mixing barrel slowly and quantitatively. The feed amount of PE materials per unit time is often related to the diameter of the feed pipe. The larger the diameter, the more materials can be fed at the same time, and the smaller the diameter, the less materials can be fed per unit time. When adding auxiliary materials to PE materials for mixing, the diameter of the feed pipe is often fixed, so the feed amount per unit time is also fixed. In actual work, different feed speeds are often required, and the fixed structure of the pipe diameter is not convenient for adjusting the feed amount per unit time, so it needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the utility model is that it is inconvenient to adjust the feed amount per unit time during the mixed processing of PE materials due to the influence of the feed pipe diameter.

[0006] As an improvement, a fixed plate is fixedly connected to one side of the feed pipe, and a rotating motor is arranged on the fixed plate; a rotating shaft is fixedly connected to the output shaft of the rotating motor, and the rotating shaft is fixedly connected to the rotating plate.

[0007] As an improvement, a mounting box is fixedly connected to one side of the feed pipe, and a lifting motor is arranged on the mounting box; a screw rod rotatably arranged in the mounting box is fixedly connected to the output shaft of the lifting motor; a lifting plate is threadedly connected to the screw rod.

[0008] As an improvement, a guide groove connected to the feed pipe is provided on the side wall of the installation box, and a connecting rod fixedly connected to the lifting plate is provided in the guide groove; the connecting rod is fixedly connected to the plug-in cylinder.

[0009] As an improvement, a stirring motor is provided at the bottom of the mixing drum, and a stirring shaft located in the mixing drum is fixedly connected to the output shaft of the stirring motor, and a stirring blade is fixedly connected to the stirring shaft.

[0010] Beneficial effects of the utility model:

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] according to Figure 1-4 As shown: the utility model provides a quantitative feeding structure for PE material processing: it includes a support leg 1, the support leg 1 is fixedly connected to a mixing barrel 2 upward, and a feeding pipe 3 is connected above the mixing barrel 2; an entry hole 11 is provided at the upper end of the feeding pipe 3; a groove 4 is provided in the feeding pipe 3, and a rotating plate 6 is rotatably arranged in the groove 4; four circumferentially evenly distributed feeding holes 5 of different sizes are provided on the rotating plate 6, and the center of one of the feeding holes 5 is aligned with the center of the feeding pipe 3; a plug-in groove 14 is provided around each feeding hole 5, and a plug-in barrel 10 inserted into the plug-in groove 14 is slidably arranged in the feeding pipe 3 up and down.

[0019] By providing a rotating rotating plate 6 and opening feed holes 5 of different sizes on the rotating plate 6, the size of the feed hole 5 can be changed by rotating the rotating plate 6, thereby changing the feed amount of PE material per unit time.

[0020] A fixed plate 13 is fixedly connected to one side of the feed pipe 3 , and a rotating motor 12 is arranged on the fixed plate 13 ; a rotating shaft 15 is fixedly connected to the output shaft of the rotating motor 12 , and the rotating shaft 15 is fixedly connected to the rotating plate 6 .

[0021] A mounting box 9 is fixedly connected to one side of the feed pipe 3, and a lifting motor 17 is arranged on the mounting box 9; a screw rod 16 rotatably arranged in the mounting box 9 is fixedly connected to the output shaft of the lifting motor 17; a lifting plate 18 is threadedly connected to the screw rod 16. A guide groove 19 communicating with the feed pipe 3 is opened on the side wall of the mounting box 9, and a connecting rod 20 fixedly connected to the lifting plate 18 is arranged in the guide groove 19; the connecting rod 20 is fixedly connected to the plug-in cylinder 10.

[0022] The arrangement of the guide groove 19 and the connecting rod 20 can limit the rotation of the lifting plate 18 , thereby converting the rotation of the screw rod 16 into the movement of the moving plate, and transmitting the movement to the plug-in cylinder 10 through the connecting rod 20 .

[0023] A stirring motor 8 is disposed at the bottom of the mixing drum 2 , and a stirring shaft 7 located in the mixing drum 2 is fixedly connected to the output shaft of the stirring motor 8 , and a stirring blade is fixedly connected to the stirring shaft 7 .

[0024] The provision of the stirring motor 8 can increase the mixing uniformity of the PE material and the auxiliary material.

[0025] Principle of the utility model

[0026] When the utility model is used, auxiliary materials are added to the mixing barrel 2, and the melted PE material enters the plug-in barrel 10 in the feed pipe 3 through the entry hole 11, and enters the mixing barrel 2 through the feed hole 5, so as to be mixed and stirred with the auxiliary materials such as additives in the mixing barrel 2. The stirring motor 8 is started to drive the stirring shaft 7 to rotate, thereby increasing the mixing efficiency of the PE material and the auxiliary materials.

[0027] When the feed rate per unit time of PE material needs to be changed, when there is no material in the feed pipe 3, start the lifting motor 17, so that the lifting plate 18 drives the plug-in cylinder 10 to move upward, and the plug-in cylinder 10 is separated from the plug-in slot 14; start the rotating motor 12, so that another feed hole 5 rotates into the feed pipe 3; reverse the lifting motor 17, and the plug-in cylinder 10 is inserted into the plug-in slot 14. At this time, PE material can continue to be added to the mixing cylinder 2. Due to the change of the feed hole 5, the feed rate per unit time of the molten PE material will also change. Therefore, the present application can use the rotation of the rotating plate 6 to change the size of the feed hole 5, so as to facilitate the change of the feed rate per unit time of PE material to meet different work requirements.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
