Description

Technical Field

[0001] The utility model belongs to the technical field of rounding machines, and in particular relates to a rounding machine. Background Art

[0002] In the traditional process of making pills, manual preparation is usually adopted, in which fine powders or extracts of various medicinal materials are mixed with suitable adhesive excipients, and then made into spherical or quasi-spherical preparations through kneading, rolling and other techniques. However, this manual preparation method has low efficiency.

[0003] According to relevant technologies, in order to solve the above problems, mechanical equipment is now used to form pills. Specifically, two forming rollers are quickly rotated facing each other to roll and cut the strip objects into pills, such as the patent with application number "202311774433.8".

[0004] However, when the two forming rollers of the above patent are forming the strip material, since they need to rotate quickly, the material is easily ejected by force, thereby leaving the forming position, resulting in failure of pill making.

[0005] Therefore, how to prevent the strip material from being forced to fly out during the pelletizing process is a technical problem that those skilled in the art need to solve urgently. Utility Model Content

[0006] In order to solve the technical problems mentioned in the background technology, the utility model provides a rounding machine, which includes: an extrusion mechanism for extruding strip materials; a turning roller, a groove is provided on the upper surface of which, and a receiving component for receiving the strip materials is provided in the groove; and a rounding mechanism, a rounding position on which is located directly below the turning roller; wherein the turning roller rotates one circle to cut off the strip material extruded by the extrusion mechanism and at the same time feeds the strip material into the rounding position; and the lower surface of the turning roller covers the rounding position to prevent the strip material from jumping out of the rounding position during the forming process.

[0007] Furthermore, the rounding mechanism includes: two forming rollers; the two forming rollers are arranged in parallel and located in the same horizontal plane, so that the rounding position is formed between the two forming rollers.

[0008] Furthermore, the forming roller is provided with a plurality of annular grooves; the two forming rollers are arranged adjacent to each other so that a rounded channel is formed between the annular groove on one forming roller and the corresponding annular groove on the other forming roller.

[0009] Furthermore, the groove is opened along the axial direction of the turning roller, and its cross section is fan-shaped.

[0010] Furthermore, the material receiving assembly includes: a plurality of conveying rollers, each of which is disposed in the groove and arranged along the length direction of the groove.

[0011] Furthermore, the extrusion mechanism comprises: a discharge nozzle, and the discharge nozzle is located in the area where the groove is located.

[0012] Furthermore, the side wall of the turning roller is close to the end surface of the discharge nozzle so as to cut off the strip material at the discharge nozzle during rotation.

[0013] Furthermore, the turning roller is arranged parallel to the forming roller.

[0014] Furthermore, adjacent annular grooves are arranged closely to form a cutting portion.

[0015] The beneficial effect of the utility model is that the turning roller of the rounding machine is located above the rounding mechanism, and its upper end surface is used to receive the strip material extruded by the extrusion mechanism, and drives the strip material to fall into the rounding position below by rotating; at the same time, the material extruded by the extrusion mechanism is cut off during the rotation; and each time the turning roller rotates one circle, when the strip material on the turning roller falls into the rounding position, the turning roller continues to rotate until it is reset. At this time, a "semi-sealed" area is formed between the turning roller and the rounding position, and the strip material is located in this area, thereby preventing the strip material from being forced to pop out of the rounding position during the forming process.

[0016] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the utility model. The purpose and other advantages of the utility model are realized and obtained by the structures particularly pointed out in the description and the drawings.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 , Figure 2 As shown, at least one embodiment provides a rounding machine, which includes: an extrusion mechanism 1 for extruding a strip material; a turning roller 2, a groove 21 is provided on the upper surface of which, and a receiving component 3 for receiving the strip material is provided in the groove 21; and a rounding mechanism 4, a rounding position 41 thereon is located directly below the turning roller 2; wherein the turning roller 2 rotates one circle to cut off the strip material extruded by the extrusion mechanism 1, and at the same time feeds the strip material into the rounding position 41; and the lower surface of the turning roller 2 covers the rounding position 41 to prevent the strip material from jumping out of the rounding position 41 during the forming process.

[0031] In some embodiments, the flip roller 2 is located above the rounding mechanism 4, and its upper end surface is used to receive the strip material extruded by the extrusion mechanism 1, and drive the strip material to fall into the rounding position 41 below by rotating; at the same time, the material extruded by the extrusion mechanism 1 is cut off during the rotation; and each time the flip roller 2 rotates one circle, when the strip material on the flip roller 2 falls into the rounding position 41, the flip roller 2 continues to rotate until it is reset. At this time, a "semi-sealed" area is formed between the flip roller 2 and the rounding position 41, and the strip material is located in this area, thereby preventing the strip material from being forced to pop out of the rounding position 41 during the forming process.

[0032] In some embodiments, the groove 21 is opened along the axial direction of the flip roller 2, and its cross-section is fan-shaped; the material receiving component 3 includes a plurality of conveying rollers 31 arranged along the length direction of the groove 21, and the first-level conveying roller 31 conveys the material backward after receiving the material, so that the material moves on the conveying surface formed by each conveying roller 31.

[0033] In some embodiments, the extrusion mechanism 1 includes a discharge nozzle 11, and the lower end face of the discharge nozzle 11 is flush with the conveying surface of the conveying roller 31, so as to facilitate the material to enter the conveying surface of the conveying roller 31; at the same time, the outer end face of the discharge nozzle 11 is close to the side wall of the flip roller 2 (the flip roller 2 faces the side wall of the discharge nozzle 11), so that a "scissors mouth" is formed between the two, that is, the flip roller 2 cuts off the material at the discharge nozzle 11 by rotating.

[0034] like Figure 3 , Figure 4 , Figure 5 As shown, in some embodiments, the rounding mechanism 4 includes: two forming rollers 42; the two forming rollers 42 are arranged in parallel and located in the same horizontal plane, so that the rounding position 41 is formed between the two forming rollers 42; at the same time, the turning roller 2 and the forming roller 42 are also arranged in parallel.

[0035] In some embodiments, a plurality of annular grooves 43 are provided on the forming roller 42; the two forming rollers 42 are arranged adjacent to each other so that a rounding channel 44 is formed between the annular groove 43 on one forming roller 42 and the corresponding annular groove 43 on the other forming roller 42; at the same time, the adjacent annular grooves 43 are arranged adjacent to each other to form a cutting portion 45; specifically, the two forming rollers 42 face each other and rotate to apply a downward force to the strip material, and during the rotation of the forming rollers 42, the strip material is gradually divided into a plurality of small materials through the cutting portions 45, and each small material is rotated in the rounding channel 44 by the force applied to it by the forming rollers 42 to gradually tend to a spherical shape; wherein, one forming roller 42 is movably arranged, and the initial state is as follows Figure 5 As shown, there is a gap between the two forming rollers 42. When the strip material enters the rounding position 41, the movable forming roller 42 will move toward the other forming roller 42 until the strip material enters the rounding position 41. Figure 3 As shown, after a period of time (i.e. the material is formed into a pellet), the movable forming roller 42 is reset, so that the pellet material falls into the collection position below.

[0036] In some embodiments, a guide plate is provided on the turning side of the turning roller 2 to guide the strip material into the rounding position 41 .

[0037] To summarize, the flip roller 2 of the rounding machine is located above the rounding mechanism 4, and its upper end surface is used to receive the strip material extruded by the extrusion mechanism 1, and drive the strip material to fall into the rounding position 41 below by rotating; at the same time, the material extruded by the extrusion mechanism 1 is cut off during the rotation; and each time the flip roller 2 rotates one circle, when the strip material on the flip roller 2 falls into the rounding position 41, the flip roller 2 continues to rotate until it is reset. At this time, a "semi-sealed" area is formed between the flip roller 2 and the rounding position 41, and the strip material is located in this area, thereby preventing the strip material from being forced to pop out of the rounding position 41 during the forming process.
