[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1-5As shown, the utility model proposes a mixing equipment for resin processing, including a mixing drum 1, a drum cover 2 is arranged on the top of the mixing drum 1, a mixing motor 3 is fixedly installed on the upper surface of the drum cover 2, the output shaft of the mixing motor 3 is coaxially fixedly connected with the top end of the mixing shaft 4 through a coupling, and the mixing shaft 4 movably passes through the drum cover 2 and extends into the mixing drum 1. A discharge nozzle 6 and a support foot not shown in the figure are arranged at the bottom of the mixing drum 1. The top end of the feed pipe 7 passes through the drum cover 2 and extends into the mixing drum 1, and the bottom end thereof is connected to the feed port of the conveyor to input the material to be mixed into the mixing drum 1. The above is a common structure of existing mixing equipment, which will not be described here.

[0034] In this embodiment, the stirring device includes a stirring blade 5 which is fixedly connected to the stirring shaft 4 and is located in the stirring drum 1. Through the design of the stirring blade 5, not only can the wall of the stirring drum 1 be scraped to prevent adhesion when stirring viscous raw materials, but also the scraping and brushing wear of the wall of the stirring drum 1 can be avoided when stirring powdered raw materials. By selecting different stirring methods in different application scenarios, the wear on the wall of the stirring drum 1 can be reduced without affecting the stirring effect.

[0035] Specifically, Figure 2-5 As shown, the stirring blade 5 includes a connecting sleeve 51, a connecting arm 52 and a scraper blade assembly 53. The connecting sleeve 51 is sleeved with the stirring shaft 4 and fixed by a connecting member such as a pin. There are three connecting arms 52, one end of which is integrally connected to the outer wall of the connecting sleeve 51, and the other end is detachably connected to the scraper blade assembly 53. The detachable design facilitates the replacement of other scraper blade assemblies 53 different from the present embodiment.

[0036] In this embodiment, the scraper blade assembly 53 includes a petiole 531, a scraper blade 532 fixed to one end of the petiole 531 for contacting the inner wall of the mixing drum 1 to scrape off the adhered raw materials, a fixing bar 533 fixed to the other end of the petiole 531 and rotatably connected to the connecting arm 52, and a fixing ear block 534 fixedly connected to the petiole 531 by bolts and limitedly connected to the connecting arm 52 by a polygonal pin 535.

[0037] Specifically, the opposite surfaces of the upper and lower connecting arms 52 are fixedly connected with a rotating shaft 521, and the two rotating shafts 521 are rotatably connected to the upper and lower ends of the fixing bar 533 respectively;

[0038] The fixed ear block 534, the connecting arm 52 and the rotating shaft 521 are all provided with polygonal grooves, such as Figure 5 As shown, the polygonal pin 535 includes a polygonal portion 5351 matching the polygonal groove. The polygonal pin 535 also includes a pin cap 5352 integrally connected to the top of the polygonal portion 5351 and a threaded portion 5353 integrally connected to the bottom of the polygonal portion 5351. The threaded portion 5353 is screwed with the nut thread to limit the connection and rotation between the connecting arm 52 and the wiper blade assembly 53.

[0039] Furthermore, three connecting rods 5321 are fixedly connected to the side of the scraper 532 facing the petiole 531, and the free ends of the connecting rods 5321 are movably passed through the petiole 531 and the fixing strip 533 and are limited by connecting nuts. In addition, the two ends of the scraper 532 are fixedly connected to the two ends of the petiole 531 by screws installed on the strip. This part can realize the detachable connection between the scraper 532 and the petiole 531, which is convenient for the separate replacement of the connecting rods 5321.

[0040] The working principle of this embodiment is: through the design of the stirring blade 5, not only can the wall of the mixing drum 1 be scraped to prevent sticking when stirring viscous raw materials, but also the scraping and brushing wear of the wall of the mixing drum 1 can be avoided when stirring powdered raw materials. By selecting different stirring methods in different application scenarios, the wear on the wall of the mixing drum 1 can be reduced without affecting the stirring effect.

[0041] Specifically, when a viscous raw material is stirred, as shown in the figure, the scraper 532 can contact the inner wall of the stirring drum 1, so when the stirring motor 3 drives the stirring shaft 4 and the stirring blade 5 to rotate, the material that is constantly adhering to the inner wall can be scraped off by the scraper 532;

[0042] When mixing powdered raw materials, the polygonal pin 535 can be removed first, and the scraper blade assembly 53 can be rotated to a certain angle with the rotating shaft 521 as the center. The angle is determined according to the number of sides of the polygonal portion 5351. When the polygonal portion 5351 is a regular hexagon, the scraper blade assembly 53 is rotated and adjusted at an interval of 60°, and then the polygonal pin 535 is inserted and the nut is tightened to fix it. After the scraper blade assembly 53 is rotated, its connecting rod 5321 will no longer contact the inner wall of the mixing drum 1, so it will not be worn due to continuous scraping.

[0043] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
