Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of medicinal capsule automatic machine head device, belong to the field of medicinal packaging equipment. BACKGROUND

[0002] In the production process of hard hollow capsule of medicinal packaging material, stripping, cutting and fitting are key steps. However, the existing production technology has some problems, which affects the production efficiency and product quality.

[0003] Firstly, the device disclosed in CN106963649A adopts synchronous belt transmission. Although this transmission mode is simple in structure, the synchronous belt is prone to wear and tear during long-term operation, leading to the phenomenon of dropping slag. These dropped debris can contaminate the products produced, affecting the quality and safety of the capsules. In addition, the wear and tear of the synchronous belt can also cause unstable transmission, affecting the continuity and stability of the production process, and thus reducing the production efficiency.

[0004] Secondly, the jacket assembly and the ejector rod assembly are not easy to disassemble in the prior art, which brings great inconvenience to the maintenance and repair of the equipment. Due to the complex structure of these components, disassembly and assembly require a lot of time and labor, increasing the maintenance cost of the equipment. At the same time, the increase in repair difficulty also affects the normal operation time of the equipment, reducing the production efficiency.

[0005] In addition, the weight of the fixed plate and other components is relatively large, increasing the load of the lifting motor. This not only leads to waste of energy, but also increases the operating cost of the equipment. During the production process, the motor needs to consume more electric energy to drive the lifting mechanism, thereby increasing the production cost.

[0006] Finally, the clamp mechanism disclosed in CN109514785A is relatively large in size and cannot be applied to old capsule production lines. This limits the application and promotion of the technology, making it impossible to upgrade and transform some old production lines, affecting the technological progress and development of the entire industry.

[0007] In summary, the existing medicinal capsule automatic machine head device has many problems in the stripping, cutting and fitting process, such as wear and tear of the synchronous belt transmission, difficulty in disassembling the jacket assembly and ejector rod assembly, increase in weight of the fixed plate, and excessive size of the clamp mechanism. These problems not only affect the production efficiency and product quality, but also increase the production cost and maintenance difficulty, limiting the application and promotion of the technology.

[0067] In the production process of the medicinal capsule, the capsule needs to go through key processes such as demolding, cutting and sleeving. The device realizes the automatic completion of these processes through the cooperative work of various components, improves the production efficiency and product quality.

[0068] The working principle of the head device of the automatic medicinal capsule machine is as follows:

[0069] Firstly, the ejector rod servo motor 7 drives the ejector rod movement ball screw 32 to rotate, and the ball screw converts the rotary motion of the motor into the linear motion of the ejector rod assembly 4, so that the ejector rod base 46 drives the ejector rod 44 to reciprocate along the ejector rod movement guide rail 101. The reciprocating motion of the ejector rod 44 is used to eject the capsule from the mold, realizing the demolding process. The ejector rod fixing plate 41 is detachably installed on the ejector rod base 46, which facilitates the replacement of ejector rods of different specifications to adapt to the production of capsules of different sizes.

[0070] Then, the sleeve movement servo motor 8 drives the sleeve movement ball screw 33 to rotate, and the sleeve movement ball screw drives the sleeve support seat 50 to reciprocate along the sleeve movement guide rail 102, and then the sleeve 513 realizes reciprocating motion. The front half bracket 51 and the rear half bracket 54 of the sleeve assembly 5 are detachably installed on the sleeve support seat 50, which facilitates maintenance and replacement. The reciprocating motion of the sleeve 513 is used to sleeve the demolded capsule, so as to form a complete capsule shape.

[0071] At the same time, the output end of the sleeve rotation servo motor 9 is provided with a sleeve rotation planetary reducer, which drives the sleeve 513 to rotate through the speed reduction effect of the planetary reducer. The rotation and reciprocating motion of the sleeve can realize accurate sleeving of the capsule and ensure the sleeving quality. The gear 57, spline shaft 58 and double-sided rack 59 inside the sleeve assembly 5 work cooperatively to realize stable rotation and reciprocating motion of the sleeve.

[0072] In addition, the cutting knife servo motor 65 drives the cutting ball screw 68 through the cutting planetary reducer 66, so that the cutting knife 11 fixed on the knife holder 10 reciprocates along the linear guide rail 62. The reciprocating motion of the cutting knife 11 is used to cut the capsule to the required length and shape. The linear guide rail 62 and the guide rail slider 63 provide stable guidance for the movement of the cutting knife, ensuring the accuracy and consistency of the cutting.

[0073] Finally, the demolding assembly is driven by the driving motor to make the clamp mechanism reciprocate along the guide rail installed on the box. The clamp motor 16 is engaged with the transmission shaft 17 through the gear, drives the mechanical cam 15 to move, and the mechanical cam 15 drives the upper clamp bracket 13 and the lower clamp bracket 14 to reciprocate up and down, completes the opening and closing of the clamp, and is used for clamping and transferring the capsule.

[0074] In summary, the automatic machine head device of the medicinal capsule of the application realizes automation, precision and high efficiency of capsule demolding, cutting and sleeving processes through technical means such as servo motor driving, ball screw transmission and guide rail sliding block guiding, improves the quality and efficiency of medicinal capsule production, reduces production cost and labor intensity, and has good market application prospect.

[0075] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art should be covered within the protection scope of the present application according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, and equivalent replacement or change.
