Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all the directional indicators in the present invention (such as upper, lower, left, right, front, and rear …) are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly. In addition, the descriptions related to "preferred", "less preferred", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 3, the utility model provides a screw feeder of anti-sticking material, including feed cylinder 1, set up hopper 2 on feed cylinder 1, set up screw rod 3 in feed cylinder 1, and can drive screw rod 3 and rotate the drive arrangement who carries the material in feed cylinder 1 forward, be provided with the feed inlet 101 that switches on hopper 2 and feed cylinder 1 on the feed cylinder 1, be provided with the discharge gate 102 that is located before feed inlet 101 on the feed cylinder 1, screw rod 3 includes center pin 31, set up helical blade 32 that is located before feed inlet 101 on the center pin 31 lateral wall, and set up the ejector pad 33 at center pin 31 rear portion, the front portion of ejector pad 33 has the material convex part 331 that stirs that can stir the material of feed inlet 101 department. Specifically, the spiral blade 32 is located between the inlet 101 and the outlet 102, and a step is provided between the front end of the spiral surface 332 and the front end surface of the ejector block 33 so that the front end of the spiral surface 332 forms an apex angle 333. The top corner 333 is located where the throat 101 is located.

The utility model discloses a theory of operation as follows: the material in the hopper 2 can fall into the barrel 1 under the action of gravity, and is rotated by the screw 3 to push the material in the barrel 1 forward and fall out of the discharge port 102. The position on the central shaft 31 opposite to the feed port 101 is not provided with a helical blade, so that the material in the hopper 2 can fall into the charging barrel 1, and meanwhile, the screw rod 3 rotates and simultaneously stirs the material at the feed port 101 through the stirring convex part 331, so that the material can be effectively prevented from being clamped at the feed port 101.

Further, the front side of the stirring protrusion 331 has a spiral surface 332 capable of pushing the material to move forward. With such a structure, the forward thrust of the screw 3 on the material can be increased, and at the same time, the amount of the material output from the discharge port 102 per rotation of the screw 3 can be accurately controlled by controlling the pitch and width of the spiral surface 332.

By adopting the structure, the phenomenon that the material is blocked due to the occurrence of a connecting seam between the hopper 2 and the charging barrel 1 is avoided.

Preferably, the number of the stirring protrusions 331 is two or more, generally 2 to 3, and all the stirring protrusions 331 are uniformly distributed around the central shaft 31.

As a preferred embodiment of the present invention, the driving device includes a motor 41, and the motor 41 is connected to the screw rod 3 through a gear set. Specifically, the gear set includes a first bevel gear 42 connected to the rear end of the center shaft 31, and a second bevel gear 42 connected to the output end of the motor 41 and engaged with the first bevel gear 42. The central shaft 31 is in threaded connection with the first bevel gear 42 and the screw 3 rotates to cause a tendency of the first bevel gear 42 to wind.

The above is only the preferred embodiment of the present invention, not limiting the patent scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct or indirect application is included in other related technical fields in the patent protection scope of the present invention.
