Description

Technical Field

[0001] This utility model belongs to the field of material storage and conveying technology, and particularly relates to the storage and conveying of powder and granular materials, specifically to an adjustable volume hopper for powder and granular materials. Background Technology

[0002] In the injection molding auxiliary equipment industry, various powder and granular materials are involved. Conveying hoppers are essential components for material handling and are frequently used in dryers, metering machines, feeders, and centralized feeding systems.

[0003] Existing powder and granular material hoppers come in various forms and are available in many types based on their volume. However, existing hoppers have several shortcomings. For example, the volume of the hopper is fixed, resulting in a wide variety of sizes; and because of the numerous specifications, multiple molds are required, leading to high manufacturing costs.

[0004] Therefore, a hopper with variable volume is needed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an adjustable volume hopper for powder and granular materials with a simple structure and reduced types of hoppers.

[0006] To solve the above-mentioned technical problems, this utility model provides an adjustable volume hopper for powdery and granular materials. Its main features are that the hopper has a hopper body, a hopper cover, and a feed pipe. The hopper cover is installed on the top of the hopper body. The outer wall of the feed pipe is marked with volume scale. The feed pipe is movably mounted on the hopper cover. The outer opening of the feed pipe serves as the feed inlet, and the inner opening of the feed pipe extends into the interior of the hopper body. By moving the feed pipe to adjust the height of the inner opening, the volume of powdery and granular materials entering the interior of the hopper body from the outer opening of the feed pipe can be controlled.

[0007] Preferably, a fixing seat is fixed on the hopper cover, the fixing seat having a central hole for fitting the feed pipe, and the feed pipe is adjustablely locked onto the fixing seat by a locking screw.

[0008] Preferably, the fixing seat is provided with a horizontal threaded hole and a vertical mounting hole. The fixing seat is fixed to the hopper cover through the vertical mounting hole, and the feed pipe is locked to the fixing seat through the horizontal threaded hole.

[0009] Preferably, a first sealing element is provided between the fixed base and the hopper cover, and a second sealing element is provided between the fixed base and the feed pipe.

[0010] Preferably, a discharge port is provided at the bottom of the hopper body, and a suction plate is installed at the discharge port.

[0011] Preferably, the hopper cover is provided with an air intake.

[0012] Preferably, a filter screen is provided inside the hopper body, and the feed pipe extends downward through the filter screen.

[0013] Preferably, the outer opening of the feed pipe extends from the main body of the feed pipe by bending.

[0014] This utility model discloses an adjustable volume hopper for powdery and granular materials. By adjusting the feed pipe up and down, the effective volume of the hopper can be flexibly adjusted directly within a preset range, reducing the types of hoppers and saving costs during manufacturing.

[0020] To make the technical problem solved by this utility model clearer, the present utility model is further described below with reference to embodiments and accompanying drawings. The specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1 to 5 The image shows an embodiment of the adjustable volume hopper for powdery and granular materials according to this utility model, suitable for conveying powdery and granular materials. The hopper comprises a hopper body 1, a hopper cover 2, and a feed pipe 5. The hopper cover 2 is installed on the top of the hopper body 1. The outer wall of the feed pipe 5 is provided with volume markings. In this embodiment, as shown... Figure 2As shown, the volume scale markings range from 2L to 8L. The feed pipe 5 is vertically movably mounted on the hopper cover 2. The outer opening of the feed pipe 5 serves as the feed inlet, and the inner opening of the feed pipe 5 extends into the interior of the hopper body 1. By moving the feed pipe 5 and adjusting the height of the inner opening, the volume of powder or granular material entering the hopper body 1 from the outer opening of the feed pipe 5 is controlled. The outer opening of the feed pipe 5 extends from the main body of the feed pipe 5 in a bend.

[0022] like Figure 1 As shown, a fixing seat 4 is fixed on the hopper cover 2. The fixing seat 4 has a central hole for mounting the feed pipe 5. The feed pipe 5 is adjustablely locked onto the fixing seat 4 by a locking screw. The direction of the feed inlet can be any position within 360° by tightening the locking screw, facilitating actual on-site operations.

[0023] Specifically, the fixing seat 4 is provided with a horizontal threaded hole 10 and a vertical mounting hole 11. The fixing seat 4 is fixed to the hopper cover 2 through the vertical mounting hole 11, and the feed pipe 5 is locked to the fixing seat 4 through the horizontal threaded hole 10.

[0024] like Figure 1 As shown, O-rings 3 are provided between the fixed base 4 and the hopper cover 2, and between the fixed base 4 and the feed pipe 5.

[0025] like Figure 1 As shown, the bottom of the hopper body 1 is provided with a discharge port 8, and a suction plate 9 is installed on the discharge port 8 for opening and closing the discharge port 8. The hopper cover 2 is provided with an air intake 6. A filter screen 7 is provided inside the hopper body 1, and the feed pipe 5 extends downward through the filter screen 7.

[0026] Figure 5The diagram shows the dynamic changes in the position of the feed pipe as it moves up and down. By fixing the relevant volume markings on the feed pipe to the mounting base using locking screws, the hopper volume can be adjusted to the corresponding size. Therefore, the hopper volume can change with the movement of the feed pipe, ranging from 2L to 8L, matching the markings on the feed pipe. For example, if the required hopper volume is 2L, the feed pipe can be moved until the "2L" mark on it is flush with the upper surface of the mounting base. This way, the effective volume inside the hopper after material is fed in is 2L. If the required effective volume is 8L, the feed pipe can be moved upwards until the "8L" mark on it is flush with the upper surface of the mounting base. This way, the effective volume of material inside the hopper is 8L. This allows the effective volume of the hopper to be adjusted directly from 2L to 8L, replacing the original conventional hopper specifications such as 2L, 3L, 5L, and 7L, reducing the types of hoppers, saving costs during manufacturing, and the effective volume range can be flexibly set according to actual needs.

[0027] This utility model discloses an adjustable volume hopper for powdery and granular materials. By adjusting the feed pipe up and down, the effective volume of the hopper can be flexibly adjusted directly within a preset range, reducing the types of hoppers and saving costs during manufacturing.

[0028] The above descriptions are specific embodiments of this utility model and do not constitute a limitation on the scope of protection of this utility model. Any modifications and variations made to the technical concept of this utility model should be included within the scope of protection of this utility model.
