Description

Technical Field

[0001] The utility model relates to the field of dripping pill production, in particular to a forming column and a dripping pill machine. Background Art

[0002] With the development of the production process of dripping pills and the growth of demand, more and more fields are involved in it, especially the fields of medicine, food, and health care products are growing rapidly. In the process of dripping pills, the glue liquid wraps the core liquid and drips out from the dripper. Its molding must be cooled into a solid state by circulating cooling grease in the molding column before it can be molded. In order to observe the molding state of the dripping pills, the material of the molding column must be transparent for easy observation. Currently, the commonly used materials are transparent materials such as acrylic, plexiglass, high-peng silicon, and glass. When making the molding column, due to the particularity of the process equipment, the molding column needs to be lifted up and down during use, which makes it very easy to break at the connection between the bottom support of the molding column and the entire column, and it is easier to break when disassembling the molding column. The broken molding column not only affects the production efficiency of the dripping pills, but also increases the production cost. Utility Model Content

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0034] like Figures 1 to 6As shown, this embodiment provides a forming column, including a central tube 1 and an outer tube structure which are vertically arranged and sleeved with inner and outer intervals. The outer tube structure is provided with a cooling medium inlet for allowing the cooling medium to flow into the central tube 1 through the outer tube structure; the central tube 1 includes a transparent tube 11, an upper metal tube 12 and a lower metal tube 13 which are arranged in sequence from top to bottom, the lower end of the transparent tube 11 passes through the outer tube structure, and the transparent tube 11 and the upper metal tube 12 are connected at their joints by an annular forming column base 3, and the upper metal tube 12 and the lower metal tube 13 are detachably connected at their joints by a connecting clamp 4; a metal protective cover 5 is also sleeved outside the transparent tube 11 and below the outer tube structure, the upper end of the metal protective cover 5 is connected to the outer tube structure, and the lower end thereof is connected to the forming column base 3.

[0035] Among them, the entire forming column is used to be installed on the pill machine so that it can move up and down, and the dripper 81 of the pill machine is directly opposite to the top opening of the central tube 1; the cooling medium inlet can be used to allow the cooling medium (generally cooling circulating grease, such as paraffin) to flow into the central tube 1 through the outer cylinder structure. When the pill machine processes the pills, the glue-wrapped core liquid drips out from the dripper 81 and drips into the central tube 1, and is cooled by the cooling medium to become solid and formed. In order to observe the forming state of the pills, the upper part of the central tube 1 must be made of transparent material. In order to facilitate connection with other structures and subsequent disassembly and assembly, the lower part of the central tube 1 needs to be made of metal material, and the transparent material and the metal material are connected by a forming column base 3; due to the long length of the entire central tube 1, the forming column base 3 is arranged close to the bottom of the entire central tube 1 in the prior art, which is not only inconvenient for the subsequent disassembly and assembly of the forming column, but also very easy to break at the position of the forming column base 3 (i.e. the position where the glass material is connected to the metal material) during lifting, moving and disassembly.

[0036] In this embodiment, the metal material part is divided into two parts, an upper metal tube 12 and a lower metal tube 13. The upper metal tube 12 and the lower metal tube 13 are fixed by a connecting clamp 4, and can be easily disassembled. The length of the upper metal tube 12 is relatively short, and the sum of the length of the upper metal tube 12 and the length of the transparent tube 11 is less than the length of the lower metal tube 13. The position of the connecting clamp 4 is roughly located in the middle of the central tube 1. After disassembly at this position, the length of the central tube 1 above this position is relatively shortened, which can reduce the breakage at the bottom bracket 3 of the molding column; in addition, the setting of the metal protective cover 5 can make the bottom bracket 3 of the molding column become one with the entire molding column, effectively preventing the breakage at the connection of the bottom bracket 3 of the molding column.

[0037] Therefore, the forming column in this embodiment can realize the disassembly and assembly of the forming column conveniently and quickly by dividing the metal material part of the central tube 1 into two sections and connecting them through the connecting clamp 4, thereby solving the problem of inconvenient disassembly of the forming column of the existing pill machine. At the same time, the position of the connecting clamp 4 is roughly located in the middle of the central tube 1. After disassembly at this position, the length of the upper central tube 1 to be disassembled is shortened, which can reduce the possibility of the central tube 1 breaking at the bottom support 3 of the forming column during the removal process; at the same time, the setting of the metal protective cover 5 can make the central tube 1, the bottom support 3 of the forming column and the outer cylinder structure become one. During the lifting, moving or disassembly of the forming column, the connection between the central tube 1 and the bottom support 3 of the forming column is not subject to external force, which more effectively avoids its breakage, solves the problem of easy breakage of the forming column of the existing pill machine, and greatly improves the service life of the forming column.

[0038] In a specific implementation, the cross-sectional shape of the portion of the metal protective cover 5 that is disposed outside the central tube 1 is arc-shaped, that is, the metal protective cover 5 only surrounds a portion of the central tube 1, which does not affect the observation of the pill forming condition.

[0039] For example, refer to Figure 1 and Figure 2 The metal protective cover 5 includes a support plate 51 and an arc tube 52 connected up and down. The support plate 51 can be clamped and fixed with the bottom of the outer tube structure. The cross-sectional shape of the arc tube 52 is an arc. The bottom of the arc tube 52 can be fixed with the molded column base 3 (for example, welded).

[0040] Generally, the outer cylinder structure is a cylindrical structure, and the support plate 51 can be a semicircular plate body, which is folded upward on the outer circumference of the support plate 51 to form a folded edge 511. The size of the support plate 51 matches the outer diameter of the outer cylinder structure, and the support plate 51 can be against the bottom of the outer cylinder structure. The folded edge 511 is clamped on the outer edge of the outer cylinder structure, and the metal protective cover 5 can be clamped and fixed to the outer cylinder structure after being clamped. The arc length of the arc cylinder 52 along the circumferential direction is preferably 1 / 5-1 / 3 of the circumference of the central tube 1, so as to facilitate the observation of the formation of the drop pills.

[0041] The molding column base support 3 is a tubular structure. When connected, the lower end of the transparent tube 11 and the upper end of the upper metal tube 12 are bonded by a glue layer, and the molding column base support 3 is threadedly connected to the upper metal tube 12 .

[0042] Further, see Figure 1The outer cylinder structure includes an inner cylinder body 21 and an outer cylinder body 22 which are spaced apart from each other. A gap is left between the bottom of the inner cylinder body 21 and the bottom of the outer cylinder body 22. The lower part of the transparent tube 11 passes through the inner cylinder body 21 and the outer cylinder body 22 in sequence and passes out from the bottom of the outer cylinder body 22. The top opening position of the inner cylinder body 21 is higher than the top opening position of the outer cylinder body 22 and the top opening position of the center tube 1. The bottom side wall of the inner cylinder body 21 is connected with a liquid inlet pipe 211, and the bottom side wall of the outer cylinder body 22 is connected with an overflow return liquid pipe 221. The liquid inlet pipe 211 can pass through the outer cylinder body 22, and the port of the liquid inlet pipe 211 constitutes the cooling medium inlet.

[0043] The outer cylinder 22 and the inner cylinder 21 are both cylindrical structures with an open top and a closed bottom. The liquid inlet pipe 211 is the cooling medium inlet, and the overflow return pipe 221 is the cooling medium overflow outlet. An overflow cavity is formed between the outer cylinder 22 and the inner cylinder 21, and an inlet cavity is formed between the inner cylinder 21 and the central tube 1. When in use, the cooling grease enters the inlet cavity through the liquid inlet pipe 211, and overflows from the upper end of the central tube 1 into the central tube 1. The excess cooling grease entering the central tube 1 overflows into the overflow cavity through the inlet cavity, and then enters the overflow return pipe 221. The inner cylinder 21 and the outer cylinder 22 cooperate to allow the cooling medium to overflow into the central tube 1, and the excess cooling medium entering the central tube 1 overflows into the overflow cavity, which can ensure that the flow rate of the cooling medium flowing into the central tube 1 is more stable, so as to ensure the molding quality of the droplets.

[0044] Generally, the liquid inlet pipe 211 and the overflow return pipe 221 are arranged vertically opposite each other, and the installation position of the metal protective cover 5 is directly below the liquid inlet pipe 211 and the overflow return pipe 221. The above-mentioned folded edge 511 is flush with the bottom of the overflow return pipe 221, which makes it easier to observe the formation of the drop pills during normal production.

[0045] The main body of the entire forming column is made of transparent material to facilitate observation of the pill forming process. Specifically, the outer cylinder 22, the inner cylinder 21, the liquid inlet pipe 211, the overflow return pipe 221 and the transparent tube 11 in the central tube 1 are made of transparent materials, such as acrylic, organic glass, high-carbon silicon, glass, etc. The metal protective cover 5, the upper metal tube 12 and the lower metal tube 13 of the central tube 1, the forming column base 3 and the connecting clamp 4 can be made of stainless steel, such as 304 stainless steel or 316 stainless steel.

[0046] Further, see Figure 3 and Figure 4 An annular fixed disk 61 is also sleeved on the outer cylinder structure, and a plurality of radially movable clamping strips 62 are circumferentially spaced on the fixed disk 61. The clamping strips 62 can abut against the outer wall of the outer cylinder structure, and the clamping strips 62 can be connected to the fixed disk 61 through corresponding fasteners 63.

[0047] The fixed disk 61, the clamping strip 62 and the fastener 63 constitute the forming column fixture 6, and the shape of the fixed disk 61 can adopt a plate structure with an inner circle and an outer square. When in use, the fixed disk 61 is fixed on the operating platform 8 of the pill machine and is fixed when in use. When the forming column needs to be lifted or moved, the clamping strip 62 moves radially outward without clamping the forming column. After moving to a suitable height, each clamping strip 62 moves radially inward and presses against the outer wall of the outer cylinder structure, and then the clamping strip 62 is fixed by a corresponding fastener 63 (such as a locking screw). The upper part of the forming column can be prevented from shaking during the production of the pills, and plays a fixing role. When the forming column needs to be disassembled, first loosen the screws on the clamping strip 62, move each clamping strip 62 radially outward, and then loosen the connecting clamp 4, and the upper half of the forming column can be removed.

[0048] Further, see Figure 3 , Figure 5 and Figure 6 An inner protective ring 71 is also sleeved on the lower metal tube 13 . The inner protective ring 71 can be inserted into the outer protective ring 72 and axially limited by the outer protective ring 72 .

[0049] The inner protective ring 71 and the outer protective ring 72 constitute the molding column protector 7, and the two are concentrically arranged. When in use, the outer protective ring 72 is fixed on the operating platform 8 of the pill machine. The shape of the outer protective ring 72 is generally a circular ring structure, and the inner protective ring 71 can be a circular ring structure, or it can be a Figure 5 and Figure 6 The mushroom head shaped structure shown in the figure can abut against the upper end surface of the outer protective ring 72 to form an axial limit. The molding column protector 7 is located at the upper part of the lower metal tube 13 and is arranged near the connecting clamp 4, which can add a force point, increase the contact area between the molding column and the operating platform 8, effectively prevent the shaking of the molding column, provide support and protection for the molding column, and improve the stability of the structure.

[0050] Further, see Figure 3 The present embodiment also provides a pill dropping machine, which includes an operating platform 8, a dripper 81 and the above-mentioned forming column; the dripper 81 and the forming column are arranged on the operating platform 8 with an upper and lower interval, and the dripper 81 is located above the forming column and arranged opposite to the central tube 1.

[0051] The forming column and the pill machine can be applied to the fields of food, medicine, health care products, cigarette popping beads production, etc. The dripper 81 is the outlet of the pills, and the finished product enters the central column from the dripper 81. The pill machine includes the above-mentioned forming column, which has the same effect, not only facilitates the observation of the pill forming, but also solves the problem that the current forming column is easy to break and inconvenient to disassemble.

[0052] Furthermore, a lifting drive device 9 is provided on the operating platform 8 and below the forming column. The lifting drive device 9 is connected to the lower metal pipe 13 and can drive the forming column to rise and fall.

[0053] The lifting drive device 9 can adopt a lifting motor, for example, as a power source for lifting the molding column, so that the molding column can be freely lifted and lowered according to the process requirements.

[0054] The above is only an illustrative embodiment of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model.
