Description

Technical Field

[0001] The present application relates to the technical field of extrusion spheronization, and in particular to a material conveying device for a drug extrusion spheronization machine. Background Art

[0002] Extrusion spheronization is currently the most widely used method for preparing small pellets. The extrusion spheronization method requires at least two machines, an extruder and a spheronization machine, to complete the pelleting process. With the advancement of technology, the extruder and the spheronization machine are connected through automation to become a fully automatic extrusion spheronization machine, which greatly improves production efficiency and product quality stability.

[0003] The patent document with patent publication number CN219252520U discloses a micro-pellet extrusion spheronization machine, which includes a barrel, a discharge pipe is provided at the bottom of the barrel, and a spheronization machine is provided below the entire barrel. The material is discharged through the barrel, and the discharged pellets fall into the spheronization machine below, thereby realizing the spheronization process, which has certain positive significance. However, there are also shortcomings. For example, the material extruded from the barrel automatically falls under the action of gravity, so it is easy to cause the weight of each pellet to be different, especially when the viscosity of the material inside the barrel is not sufficiently uniform, the weight of the extruded material is different, so the timing of breaking is also different, which leads to differences in specifications between the pellets, affecting the quality of the product.

[0021] The present application will now be described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0022] like Figure 1-4 As shown, a material conveying device of a drug extrusion spheronization machine includes a conveying pipe, an extrusion barrel 3, a conveying plate 4 and a cutting roller 6; a feed port 1 is provided on the conveying pipe, the extrusion barrel 3 is arranged at the end of the conveying pipe away from the feed port 1, and an extrusion port 30 is provided on the extrusion barrel 3; the conveying plate 4 is inclined, and a relatively higher end is connected to the extrusion port 30, a relatively lower section of the conveying plate 4 is internally rotatably embedded with a rotating roller 7, and a cutting knife 60 is circumferentially arranged on the cutting roller 6, when the side of the cutting knife 60 away from the cutting roller 6 points to the rotation axis of the rotating roller 7, the side of the cutting knife 60 away from the cutting roller 6 abuts against the outer peripheral wall of the rotating roller 7; an end of the conveying plate 4 located on the side of the cutting roller 6 away from the extrusion barrel 3 is provided with a discharge port.

[0023] An auger blade conveying mechanism 20 is provided inside the conveying pipeline. When the material enters from the feed inlet 1 of the conveying pipeline, it gradually moves toward one end of the extrusion barrel 3 under the action of the auger conveying blades.

[0024] The extrusion barrel 3 is conical, and the relatively larger end is connected to the conveying pipe, and the center of the end of the extrusion barrel 3 away from the conveying pipe is relatively lower than the center of the entire conveying pipe, so that the friction between the material and the lower half of the side wall of the extrusion barrel 3 is smaller when the material moves toward the extrusion port 30, thereby reducing the friction generated by the material's own gravity to a certain extent, so as to ensure that it has a more uniform aggregation when it finally comes out of the extrusion port 30 at the end of the extrusion barrel 3 away from the conveying pipe 2, and avoid the columnar material extruded from the extrusion port 30 from being partially loose and affecting the quality of subsequent pellets.

[0025] The supporting plate 4 is arranged at an angle, and after the material is extruded from the extrusion port 30 , the columnar material will move downward along the supporting plate 4 .

[0026] The support plate 4 has a certain thickness. A rotating roller 7 is rotatably embedded inside the support plate 4 . A portion of the outer peripheral wall of the rotating roller 7 is located on the surface of the support plate 4 .

[0027] When the cutter 60 on the cutting roller 6 is rotating, when the side of the cutter 60 away from the cutting material is just facing the rotation axis of the rotating roller 7, the side of the cutter 60 away from the cutting roller 6 just abuts against the outer peripheral wall of the rotating roller 7 and drives the rotating roller 7 to rotate at the same time.

[0028] As the columnar material moves downward along the conveying plate 4, the material will be cut by the rotating cutter 60 and the outer peripheral wall of the rotating roller 7. As the cutting roller 6 rotates and the material continues to move downward, the columnar material flow will be gradually cut into a block structure and then enter the rounding machine for rounding.

[0029] In some other embodiments, there may be a plurality of extrusion ports 30 , such as three.

[0030] In some other embodiments, a plurality of cutters 60 may be provided, such as six.

[0031] Under the action of the supporting plate 4, the cutting roller 6 and the rotating roller 7, the material will be gradually cut into block structures of the same size, and the movement of the material and the cutting process can occur synchronously without affecting each other, thereby improving production efficiency; in addition, the rotation of the cutter 60 is controlled by the servo motor, and the movement of the material is controlled by the auger blade conveying structure, thereby ensuring that the specifications of each cut material block are the same. Compared with the traditional material blocks broken by gravity, the material blocks cut out by the structure adopted in this application are of better quality; in addition, the rolling cutter 60 is safer than the cutter 60 that "straight up and down" in the incision direction.

[0032] It should be noted that the cutting roller 6 and the auger blade conveying mechanism 20 are controlled by the corresponding PLC program, and the automatic operation of the PLC program combined with the servo motor control structure is already common in the field of automation and is a prior art, and will not be repeated in this embodiment.

[0033] In some further embodiments, a limiting groove 40 is provided on the supporting plate 4 along the material conveying direction, and one end of the limiting groove 40 facing the extrusion cylinder 3 is connected to the extrusion port 30 .

[0034] In order to ensure that the columnar material can be transported in a straight line along the supporting plate 4 , a limiting groove 40 is correspondingly provided on the conveying plate. The limiting groove 40 has a certain length and is butted against the extrusion port 30 at one end facing the extrusion cylinder 3 .

[0035] The number of the limiting grooves 40 is the same as the number of the extrusion ports 30 .

[0036] In some further embodiments, a rotatable rolling column 41 is provided at the bottom of the limiting groove 40, and the number of the rolling columns 41 is multiple, and the multiple rolling columns 41 are arranged at intervals along the material conveying direction.

[0037] In order to further reduce the friction between the columnar material and the supporting plate 4 during the conveying process, a plurality of rolling columns 41 are rotatably arranged at the bottom of the limiting groove 40, and the rolling columns 41 are arranged along the length direction of the limiting groove 40, that is, the conveying direction of the columnar material, so as to optimize the sliding friction to rolling friction.

[0038] In some further embodiments, a working chamber 5 is provided at one end of the supporting plate 4 away from the extrusion cylinder 3 , and a cutting roller 6 is located in the working chamber 5 .

[0039] Exemplarily, the working chamber 5 is a chamber enclosed on the supporting plate 4, and both ends of the working chamber 5 along the material conveying direction are open for the entry and exit of materials.

[0040] Among them, the cutting roller 6 is located in the working chamber 5, and correspondingly, the rotating roller 7 is located on a section of the conveying plate 4 in the working chamber 5. Firstly, it can prevent harm to the operating personnel, and secondly, it can prevent debris from affecting the normal operation of the cutting roller 6 and the rotating roller 7.

[0041] In some further embodiments, a rotating frame 8 is provided in the working chamber 5, and the rotating frame 8 is arranged on the side of the cutting roller 6 away from the extrusion cylinder 3; the tangent direction of the rotating frame 8 close to the supporting plate 4 is opposite to the material flow direction.

[0042] The rotating frame 8 is located downstream of the cutting roller 6 and is mainly used to break up the cut material blocks to prevent the "brand new" cut surfaces produced by cutting in the material blocks from sticking to each other.

[0043] The tangent direction of a portion of the rotating frame 8 close to the supporting plate 4 is just opposite to the flow direction of the material block, so as to fully break up the material.

[0044] In some further embodiments, the rotating frame 8 includes a rotating disk 80 and a paddle 81, the number of the rotating disks 80 is two, and the two rotating disks 80 are arranged at intervals; the two ends of the paddle 81 are respectively rotatably arranged on opposite sides of the two rotating disks 80, the number of the paddles 81 is multiple, and the multiple paddles 81 are arranged at intervals along the circumference of the rotating disk 80.

[0045] Exemplarily, two rotating disks 80 are rotatably set on the two side walls of the working chamber 5, and one of them is rotated by a servo motor. A plurality of paddles 81 are rotatably set between the two rotating disks 80. The rotation setting of the paddles 81 can prevent the rotating frame 8 from generating mechanical impact on the material block during rotation, which may cause excessive deformation of the material block and affect the subsequent rounding process.

[0046] When the rotatable paddle 81 contacts a material block, it can adaptively rotate, thereby reducing the impact on the material block, but can also break up the material block.

[0047] In some further embodiments, the discharge port is disposed at an end of the working chamber 5 away from the extrusion cylinder 3 .

[0048] Specifically, the discharge port is arranged on the working chamber 5 , that is, the end of the working chamber 5 away from the extrusion cylinder 3 .

[0049] In some further embodiments, a feeding pipe 50 is provided on the working chamber 5 .

[0050] It is conceivable that in order to further avoid adhesion between the newly cut material pieces, a certain amount of powdered material can be introduced into the working chamber 5 to adaptively wrap the new cut surface produced by the cutting to avoid adhesion and aggregation.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
