Description

Technical Field

[0001] The utility model relates to the technical field of loss-in-weight scales, in particular to a powder feeding device for a loss-in-weight scale. Background Art

[0002] The existing loss-in-weight weighing feeding device is as shown in the attached manual. Figure 3 , Figure 4 As shown, it includes an upper feeding pipe 90 and a lower feeding pipe 91, the lower feeding pipe 91 is connected to the measuring bucket of the loss-in-weight scale and is fixedly connected, the upper feeding pipe and the lower feeding pipe are of equal diameter and are separated from each other, the upper feeding pipe and the lower feeding pipe are connected by an elastic sleeve 92, and the ends of the elastic sleeve are relatively fixedly connected to the upper feeding pipe and the lower feeding pipe. Since the loss-in-weight scale needs to be cleaned when the material is replaced, the loss-in-weight scale is movable. Since the upper feeding pipe and the lower feeding pipe are of equal diameter, it is difficult to align the loss-in-weight scale after repositioning; and during the working process, the upper feeding pipe 90 and the lower feeding pipe 91 are prone to offset, and the elastic sleeve is also tilted and stretched, causing the elastic sleeve to pull the lower feeding pipe, resulting in inaccurate weighing; at the same time, the powder material entering from the upper feeding pipe is easy to accumulate on the elastic sleeve, and the powder material on the elastic sleeve will also randomly and indefinitely enter the loss-in-weight scale, further resulting in inaccurate subsequent feeding of the loss-in-weight scale. Utility Model Content

[0003] The utility model aims to provide a loss-in-weight weighing powder feeding device, which can avoid pulling the feed pipe and powder material accumulation by arranging a feed pipe and a supply pipe large and small pipe and inserting the supply pipe into the feed pipe, and can effectively improve the weighing accuracy of the powder material.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A powder feeding device for a loss-in-weight scale comprises a feeding pipe fixed to the upper end of the loss-in-weight scale, and a supply pipe is arranged above the feeding pipe;

[0006] The diameter of the feed pipe is larger than that of the supply pipe, and the lower end of the supply pipe is inserted into the feed pipe.

[0007] The powder material enters the feed pipe through the feed pipe, and then enters the weighing hopper of the loss-in-weight scale; by inserting the feed pipe into the feed pipe, even if the feed pipe and the feed pipe are relatively offset, the feed pipe is always in the feed pipe, and the powder material passing through the feed pipe can completely enter the feed pipe, thereby ensuring the stability of the feeding. At the same time, there will be no relative pulling between the feed pipe and the feed pipe, thereby avoiding the influence of the loss-in-weight scale on the accuracy of powder weighing.

[0008] The utility model is further configured as follows: the feed pipe and the feed pipe are arranged vertically, and the feed pipe and the feed pipe are not arranged obliquely to prevent the powder material from accumulating on the inner wall of the pipe, thereby ensuring smooth and accurate material replenishment.

[0009] The utility model is further configured as follows: a flexible protective sleeve is provided on the outside of the feed pipe, the lower end of the flexible protective sleeve is fixed to the outer wall of the upper end of the feed pipe by a first clamp, and the upper end of the flexible protective sleeve is fixed to the outer wall of the feed pipe by a second clamp, and the flexible protective sleeve can prevent internal dust from overflowing and external impurities from entering the loss-in-weight scale. The hole of the flexible protective sleeve can be a cylindrical plastic bag with openings at both ends, and the flexible protective sleeve is connected by a clamp, which can facilitate the installation and removal of the flexible protective sleeve, thereby facilitating the cleaning and maintenance of the loss-in-weight scale.

[0010] The utility model is further configured as follows: the middle part of the flexible protective sleeve is loosely configured, so that even if the feeding pipe and the feed pipe are relatively displaced, the flexible protective sleeve can also be adaptively deformed, thereby avoiding the flexible anti-slip sleeve from pulling the feed pipe and improving the accuracy of the loss-in-weight scale.

[0011] The outstanding effects of the utility model are:

[0012] Compared with the prior art, by setting the feed pipe and the supply pipe with large and small pipes and inserting the supply pipe into the feed pipe, pulling the feed pipe and the accumulation of powder materials can be avoided, and the weighing accuracy of the powder materials can be effectively improved;

[0013] The flexible protective cover can prevent powder material from overflowing or foreign impurities from entering the loss-in-weight scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The following references Figure 1 to Figure 2 The utility model is described as follows:

[0024] A powder feeding device for a loss-in-weight scale, comprising a feed pipe 101 fixed to the upper end of a loss-in-weight scale 10, wherein a feed pipe 20 is provided above the feed pipe 101;

[0025] The diameter of the feed pipe 101 is greater than the diameter of the supply pipe 20 , and the lower end of the supply pipe 20 is inserted into the feed pipe 101 .

[0026] The powder material enters the feed pipe through the feed pipe, and then enters the weighing hopper of the loss-in-weight scale; by inserting the feed pipe into the feed pipe, even if the feed pipe and the feed pipe are relatively offset, the feed pipe is always in the feed pipe, and the powder material passing through the feed pipe can completely enter the feed pipe, thereby ensuring the stability of the feeding. At the same time, there will be no relative pulling between the feed pipe and the feed pipe, thereby avoiding the influence of the loss-in-weight scale on the accuracy of powder weighing.

[0027] The feed pipe 20 and the feed pipe 101 are arranged vertically, and the feed pipe 20 and the feed pipe 101 are not arranged obliquely, which can prevent the powder material from accumulating on the inner wall of the pipe, thereby ensuring smooth and accurate feeding.

[0028] A flexible protective sleeve 30 is provided on the outside of the feed pipe 101. The lower end of the flexible protective sleeve 30 is fixed to the outer wall of the upper end of the feed pipe 101 through a first clamp 31, and the upper end of the flexible protective sleeve 30 is fixed to the outer wall of the feed pipe 20 through a second clamp 32. The flexible protective sleeve can prevent internal dust from overflowing and external impurities from entering the loss-in-weight scale. The hole of the flexible protective sleeve can be a cylindrical plastic bag with openings at both ends. The flexible protective sleeve is connected by a clamp, which can facilitate the installation and removal of the flexible protective sleeve, thereby facilitating the cleaning and maintenance of the loss-in-weight scale.

[0029] The middle part of the flexible protective sleeve 30 is loosely arranged, so that even if the feeding pipe 20 and the feeding pipe 101 are relatively displaced, the flexible protective sleeve can also be adaptively deformed, thereby avoiding the flexible anti-slip sleeve from pulling the feeding pipe and improving the accuracy of the loss-in-weight scale.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
