Problems solved by technology

[0004] The existing feeder has the following defects: due to the large fluctuations in the amount of material in the storage box, the discharge speed fluctuates greatly, resulting in the material pressure sensed by the extruder connected to the discharge port of the feeder. Unstable, resulting in large fluctuations in the uniformity and thickness of the product during the production process, which is difficult to control and the pass rate of the product is low

Embodiment Construction

[0017] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the present invention or go beyond the definition of the appended claims range.

[0018] Such as figure 1 As shown, the two-stage feeder of this embodiment includes a first-stage feeder 1 and a second-stage feeder. The first stage feeder includes twin-screws and a motor that drives the twin-screws. A gearbox I7 is arranged between the twin-screws and the motor. The discharge port of the first stage feeder is connected with the feed port of the second stage feeder through the feed pipe 5 . The second-stage feeder includes a material storage box 3 and a twin-screw rod 2. The lower part of the material storage box is horizontally provided wit...

Abstract

The invention provides a two-level discharging device, which comprises a first-level discharging device and a second-level discharging device, wherein a discharge hole of the first-level discharging device is connected with a feeding hole of the second-level discharging device through a discharging pipeline. By the two-level discharging device, the problem of large discharging speed fluctuation of the conventional discharging device is solved; and the two-level discharging device is reasonably designed, has a simple structure and makes materials uniformly discharged.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a feeder. Background technique [0002] With the progress and development of manufacturing technology, the food industry, packaging industry, pharmaceutical industry and electrical industry have continuously put forward new requirements for the feeder. The feeder is usually used in conjunction with the extruder to prepare materials with a certain uniformity and thickness. [0003] The existing feeder can be divided into single-screw feeder and twin-screw feeder according to the screw form, both of which are driven by a motor to rotate the screw. When the screw rotates, the material is pushed out from the discharge port and enters the subsequent production process. Chinese patent ZL200420019433.3 discloses a feeder, including a base, a material storage box, a motor, and a screw. The screw is connected to the motor, and the rotation of the motor drives the worm to push out the m...
