Description

Technical Field

[0001] The utility model relates to a double-scale electronic bulk material scale. Background Art

[0002] The most common problem encountered by bulk material scales in actual production is material blockage. The main causes of material blockage are the following two factors: First, it is affected by the working environment of the bulk material scale, which is caused by the poor flow characteristics of the material itself, the light specific gravity, or the mismatch between the bulk material scale and the production line speed; second, it is caused by the structural problems of the bulk material scale itself. From a structural analysis, the material blockage generally occurs at the upper buffer bin and the lower buffer bin.

[0003] The main problem faced by the upper buffer bin is that the single barrel value of the scale is too small. When the speed cannot keep up with the incoming material speed, it will cause backlog and blockage. In order to solve the above problems, the single barrel value of the scale is generally set large, but it will cause the lower buffer bin to have a very high flow in a short period of time, making it difficult for the subsequent processes to keep up, or cause a large amount of material to be accumulated, causing blockage in the lower buffer bin. In addition, due to site limitations, the upper and lower buffer bins cannot be infinitely enlarged and raised. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0024] refer to Figures 1 to 5

[0025] A dual-scale electronic bulk material scale comprises a chassis 1, a buffer bin 11 is arranged at the lower part of the inner cavity of the chassis, two metering barrels 31 are installed above the buffer bin, and the discharge ports of the metering barrels are connected to the buffer bin; the lower ends of the metering barrels are provided with discharge gates 34, and the upper part of the chassis is provided with a feeding mechanism 2 with two feeding troughs 24, and the lower ends of the two feeding troughs extend into the upper part of the metering barrels and are provided with feeding gates.

[0026] In this embodiment, a level meter 12 is provided in the buffer bin, and a baffle 16 is provided on the upper side of the level meter to prevent the impact of falling materials. A first air disc 15 is fixed to the side wall of the buffer bin, and its working mode has two states. One is that after the metering barrel is discharged, the vibration is stopped after a period of time to prevent the material from remaining on the bin wall; the other is that when the level meter has a signal, that is, when the buffer bin is blocked, the vibration is turned on to let the material fall.

[0027] In this embodiment, the front and rear sides of the upper portion of the metering barrel are connected to the chassis via a fixing frame 35, and a weighing sensor 33 connected to the inner wall of the chassis is fixed to an outer wall of one side of the metering barrel.

[0028] In this embodiment, a vertical cylinder 32 is provided on the outer wall of the metering barrel for mounting the weighing sensor, and one end of the discharge gate is hinged to the metering barrel, and a handle 38 extending outward and hinged to the telescopic rod of the vertical cylinder is fixed to one end of the discharge gate. The two metering barrels are symmetrical, and the two discharge gates are opened to both sides respectively, and the opening and closing of the discharge gates are controlled by the corresponding vertical cylinders.

[0029] In this embodiment, a pair of hinged seats 36 are fixed to the lower outer wall of the metering barrel, and a shaft 37 is fixed to one end of the discharge gate, and the two ends of the shaft are respectively connected to the hinged seats for rotation. Thus, the discharge gate is driven to rotate around the shaft by the vertical cylinder to realize the opening and closing of the lower port of the metering barrel.

[0030] In this embodiment, a sealing strip installation groove is provided around the lower port of the metering barrel and a sealing strip is installed thereon to ensure the sealing performance when closed.

[0031] In this embodiment, the feeding mechanism includes a feeding bin 2 with a flange 21 at the upper end. The feeding bin is divided into two feeding troughs 24 stacked on the left and right by a diversion structure 26 so as to evenly distribute the falling materials to the left and right sides; the feeding gate is installed at the lower port of the feeding trough so as to open and close the lower port of the feeding trough.

[0032] In this embodiment, one side of the feed gate is fixedly connected to one end of the swing arm 22, the middle of the swing arm is hinged to the side wall of the chassis, and a horizontal cylinder 25 is hinged to the outer side of the chassis, and the telescopic rod of the horizontal cylinder is hinged to the other end of the swing arm. When the horizontal cylinder extends, it drives the swing arm to rotate, and the feed gate is opened; when the horizontal cylinder retracts, it drives the swing arm to rotate, and the feed gate is closed.

[0033] In this embodiment, a second air disc 23 is installed on the side wall of the feed trough so that compressed air can enter the second air disc to vibrate the silo wall, thereby maintaining material flow and preventing compaction or blockage.

[0034] In this embodiment, an electric control box 14 is installed on the upper end of one side outer wall of the chassis; a bag rack 17 extending into the feed box is installed on the upper end of the chassis to facilitate dust removal. A base 13 for connecting with a frame is provided at the lower part of the chassis, and the buffer bin is fixed to the base.

[0035] The double-scale bulk material scale is in a sealed state as a whole. The feeding mechanism is fixedly connected to the feeding box above it through a flange. The electric control box is isolated outside. The door panels on the outside of the chassis are connected with hinges and are surrounded by sealing strips to prevent dust leakage.

[0036] Double scale bulk material scale action process:

[0037] In the initial state, the horizontal cylinders 25 on both sides are in the extended state, and the feed gate is open; the vertical cylinders 32 on both sides are in the extended state, and the discharge gate is closed.

[0038] The material continues to fall until it reaches the target value set by the weighing sensor 33, at which time the horizontal cylinder 25 extends and the feed gate closes. If the weighing sensor 33 on the right first determines that the material has reached the target value, the vertical cylinder 32 on the right retracts, the discharge gate 34 on the right opens, and the material falls. When the weighing sensor 33 on the right detects that the material is empty, the vertical cylinder 32 on the right extends, the discharge gate 34 on the right closes, the horizontal cylinder 25 on the right retracts, the feed gate on the right opens, and the material falls into the metering barrel 31 on the right; at the same time, the vertical cylinder 32 on the left retracts, the discharge gate 34 on the left opens, and the material falls. After the weighing sensor 33 on the left determines that the material is empty, the vertical cylinder 32 on the left extends, the discharge gate 34 on the left closes, the horizontal cylinder 25 on the left retracts, the feed gate on the left opens, and the material falls into the metering bucket 31 on the left; at the same time, the vertical cylinder 32 on the right retracts, the discharge gate 34 on the right opens, and the material falls... The metering buckets on the left and right work alternately, that is, Figure 5 shown.

[0039] If the words "first", "second" and the like are used in the above-mentioned utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0040] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).
