Description

Technical Field

[0001] The utility model relates to the technical field of drop bins, in particular to an anti-adhesion drop bin. Background Art

[0002] The drop bin is generally set at the bottom of the silo and is used for discharging materials from the silo.

[0003] The cross-section of the feeding bin is smaller than the cross-sectional area of ​​the silo. The feeding bin is arranged with a large opening on the upper side and a small opening on the lower side. When feeding, the material enters from the upper side and goes out from the lower side. However, for powder materials, such as powder for making pharmaceutical tablets, the powder itself has a certain cohesiveness. When the powder reaches the feeding bin from the silo, the material will shrink inward due to the structure of the feeding bin itself, which is larger on the upper side and smaller on the lower side. This will intensify the mutual squeezing and dependence between the powders. Under the action of gravity, the powder will clump at the bottom of the feeding bin, which will lead to an increase in the amount of powder gathered in the feeding bin or even overflow, seriously affecting the normal discharge of the material in the silo.

[0004] Therefore, there is an urgent need for an anti-sticking feeding bin to prevent powder from sticking at the bottom of the feeding bin and ensure normal material discharge. Utility Model Content

[0005] In view of the above technical problems, the utility model provides an anti-sticking feeding bin, which is used to solve the problem that the existing feeding bin has no anti-sticking mechanism, resulting in the powder material sticking at the bottom of the feeding bin and the problem of poor discharge.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A material bin with anti-sticking comprises a main body, one end of the main body is provided with a feed port, and the other end is provided with a discharge port, the opening cross-section of the feed port is larger than the opening cross-section of the discharge port, the end of the main body close to the discharge port is provided with an anti-sticking mechanism, the anti-sticking mechanism comprises a driving motor, the output end of the driving motor is provided with a lead screw, the lead screw is located in the main body and is threaded with a cutting plate, a plurality of cutting knives are equidistantly provided on the cutting plate, the cutting knives are symmetrically arranged on both sides of the cutting plate, guide grooves are provided at both ends of the cutting plate, guide rails are provided at positions of the main body corresponding to the guide grooves, the cutting plate reciprocates along the guide rails, and an overflow hole is provided on the cutting plate between two adjacent cutting knives.

[0008] Furthermore, the cross section of the cutter is an isosceles triangle structure.

[0009] Furthermore, the cutting plate is provided with a nut sleeve at the position of the lead screw, and the nut sleeve cooperates with the thread of the lead screw.

[0010] Furthermore, air inlet nozzles are symmetrically provided on both sides of the body, and the air inlet nozzles are connected to an external air source pipeline.

[0011] Furthermore, the air inlet nozzles are arranged on both sides of the body in an upward tilted manner.

[0012] Furthermore, the air inlet nozzle is located below the cutting plate.

[0013] In summary, the beneficial technical effects of the utility model are:

[0014] (1) The driving motor drives the lead screw to rotate forward and backward, and the lead screw further drives the cutting plate to reciprocate along the guide rail, and then the cutter is used to cut the bonded material, ensuring that the material can pass through the discharge port of the drop bin normally. At the same time, the mechanical anti-bonding mechanism is used instead of manual crushing, which not only reduces the labor intensity of manpower, but also avoids regular observation of the drop material.

[0015] (2) The overflow hole can ensure that the material chopped by the cutter can flow out in the opposite direction along the overflow hole when the cutter is shredding, thus avoiding the problem of the cutting plate squeezing the material into blocks.

[0016] (3) By using the upwardly inclined air inlet nozzle, air can be blown upward when crushing the material, causing the powder material to tumble, further preventing the material from sticking. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be described clearly and completely below in conjunction with the embodiments.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] See attached Figure 1-4 , shown is an anti-adhesion drop bin, comprising a main body 1, the main body 1 is a right-angled trapezoidal structure, a feed port 2 is provided at one end of the main body 1, and a discharge port 3 is provided at the other end, the feed port 2 is connected to the silo, and an auger is provided below the discharge port 3, through which the material is transported, wherein the cross section of the feed port 2 is larger than the cross section of the discharge port 3, so that the material in the silo can be accelerated to fall into the main body 1;

[0026] The end of the body 1 close to the discharge port 3 is provided with an anti-sticking mechanism, wherein the anti-sticking mechanism includes a driving motor 4 arranged on the side wall of the body 1, a lead screw 5 is provided at the output end of the driving motor 4, and the other end of the lead screw 5 is rotatably connected to the other side wall of the body 1, and a cutting plate 6 is provided on the lead screw 5. A nut sleeve 7 is provided at the position of the cutting plate 6 corresponding to the lead screw 5, and the nut sleeve 7 cooperates with the lead screw 5. When in use, the lead screw 5 is driven by the driving motor 4 to rotate forward and backward, and the lead screw 5 further acts on the cutting plate 6 to reciprocate. At the same time, cutters 8 with isosceles triangle cross-sections are symmetrically provided on both sides of the cutting plate 6. When crushing, the cutter 8 is used to quickly cut the bonded material, ensuring that the material can pass through the discharge port normally. At the same time, an overflow hole 9 is provided between two adjacent cutters 8. When the cutting plate 6 is moved, the shredded material will flow to the other side of the cutting plate 6 through the overflow hole 9, so as to avoid the cutting plate 6 and the side wall of the body 1 squeezing the material between the two into blocks;

[0027] In addition, in order to prevent the cutting plate 6 from rotating when the lead screw 5 rotates, guide grooves 10 are provided at both ends of the cutting plate 6, and guide rails 11 are provided at the positions of the side walls of the body 1 corresponding to the guide grooves 10, so that the cutting plate 6 can slide horizontally along the guide rails 11 when the cutting plate 6 reciprocates;

[0028] Furthermore, the main body 1 is symmetrically provided with air inlet nozzles 12 below the anti-sticking mechanism. The air inlet nozzles 12 are arranged on both sides of the main body 1 at an upward tilt. The air inlet nozzles 12 are connected to the external air source pipeline. When in use, the external air source is introduced into the main body 1 through the air inlet nozzles 12, and then the material is tumbled in the main body 1 by the action of the air source, thereby further achieving the purpose of crushing and preventing adhesion.

[0029] When in use, the material enters the main body 1 from the silo through the feed port 2 of the main body 1, and then the drive motor 4 is started to drive the screw 5 to rotate forward and reversely. The screw 5 further acts on the cutting plate 6 to reciprocate horizontally along the guide rail 11. The cutting plate 6 further uses the cutting knife 8 to cut the material into pieces. At the same time, the reciprocating motion of the cutting plate 6 provides space and conditions for the material to flow, thereby avoiding mutual extrusion and dependence, eliminating the conditions for adhesion, and ensuring that the material can pass smoothly from the discharge port 3.
