Description

Technical Field

[0001] The utility model relates to capsule production equipment, and more specifically to an automatic capsule mold milling machine. Background Art

[0002] Capsules are produced by a capsule machine. The mold is one of the core components of the capsule machine and is usually composed of multiple needle molds (for example, a mold is composed of 30 needle molds), and each needle mold is used to form a part of the capsule. During the production of the capsule, the capsule liquid adheres to the needle mold to form a part of the capsule. The needle mold is usually divided into a needle mold body and a needle mold cap. The length of the needle mold body is 37.9 mm, and the lower half of the capsule, that is, the capsule body, is formed through the needle mold body. The length of the needle mold cap is 31.27 mm, and the upper half of the capsule, that is, the capsule cap, is formed through the needle mold cap. The capsule cap has multiple convex points as locking points (for example, 6 locking points evenly distributed in the circumferential direction). The diameter of the capsule body is smaller than that of the capsule cap, and the capsule cap is sleeved on the capsule body and connected through the locking points to form a complete capsule.

[0002]

[0003] In the prior art, the capsule cap and the capsule body are formed by extrusion. For the capsule cap, 6 evenly distributed locking points are formed on the circular surface through the extrusion process, and the angle between each locking point is 60 degrees. During the extrusion process, the material flows around the stress point, which may cause the material on both sides of the locking point to bulge, thereby increasing the diameter of the circle and causing the circular surface to be uneven. For the capsule body, it is formed by extrusion on two sides at an angle of 90 degrees to form two symmetrical planes. Similar to the point extrusion on the circular surface, the outer diameter of the capsule body may also increase beyond the dimensional requirements due to material flow during the extrusion process. Obviously, the capsule cap and the capsule body formed according to the prior art will have bulges at the extrusion edges and the outer diameter will become larger during the extrusion process, and the dimensions cannot be accurately controlled.

[0017] Figure 2 is Figure 1 the rear view of DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.

[0019] As Figure 1 - Figure 2 shown, an automatic capsule die milling machine according to a preferred embodiment of the present invention includes a working platform 1, a rotating chuck 2, a rotating spindle 3, and a slide table assembly 4. Among them, the rotating chuck 2 is installed at the middle position of the working platform 1 to clamp and position the needle die, and two rotating spindles 3 are respectively installed on both sides of the rotating chuck 2 opposite to each other through the slide table assembly 4 to mill the capsules on the needle die. In this way, the present invention solves the problem of raised edges caused by extrusion through milling, and solves the labor cost and work efficiency through automation.

[0020] The rotary chuck 2 is a pneumatic chuck, which can clamp and fix the needle die and rotate the needle die to adjust its angle.

[0021] A milling cutter is installed at the head of each rotary spindle 3. The milling cutter is driven by the high-speed rotation of the spindle to perform machining, and is responsible for milling the circular surface of the capsule on the needle die.

[0022] Each slide table assembly 4 includes a first slide table 41 and a second slide table 42, which are used to accurately move the rotary spindle 3. In this embodiment, the first slide table 41 is an X-axis slide table, which is used to move the rotary spindle 3 left and right; the second slide table 42 is a Z-axis slide table, which is used to move the rotary spindle 3 up and down. In this embodiment, the slide tables 41 and 42 are screw slide table assemblies, which are respectively composed of screws, motors and slide rails, so that the rotary spindle 3 slides in the X-axis and Z-axis directions to achieve precise positioning.

[0023] As Figure 1 shown, the automatic capsule mold milling machine further includes a sorting machine 5 installed on the workbench 1, which is used to screen and arrange the molds to ensure that the directions of each needle are consistent. The sorting machine 5 is an automatic device, which is used to arrange the needle die body or the needle die cap in a certain direction and order, usually in ascending order, so as to facilitate the forming and production of capsules.

[0024] As Figure 1 shown, the automatic capsule mold milling machine further includes a feeding mechanism 6 installed on the workbench 1, which is used to feed the arranged molds into the processing area.

[0025] The working process of the automatic capsule mold milling machine according to the present invention includes: the sorting machine 5 first screens and arranges the disordered needle dies, and then the feeding mechanism 6 feeds the arranged needle dies into the processing area. The needle die is fixed by the rotary chuck 2 and positioned according to the angle preset by the program. The milling cutter of the rotary spindle 3 mills the circular surface of the capsule on the needle die, and the milling is controlled by a computer numerical control (CNC) system. For the capsule cap, the milling cutters of the two rotary spindles 3 process the capsules on the needle die cap at the same time, and two locking points are processed at a time. After the milling cutter withdraws, the rotary chuck 2 rotates 60°, and then two locking points are processed by the two milling cutters again. Repeat until six locking points are processed to ensure that the locking points are evenly distributed. For the capsule body, the needle die body is a two-sided symmetric plane, and only needs to be moved up and down for cutting.

[0026] The automatic capsule mold milling machine of the present invention has a simple structure, convenient operation and high processing efficiency. It is suitable for the automatic production of various capsule molds and has broad market application prospects.
