[0003] The existing flipping structure, such as a mold flipping claw for a hollow capsule mold feeder (utility model announcement number: CN204980232U), includes a mounting plate, an auxiliary block and a flipping claw are installed on the upper surface of the mounting plate, the auxiliary block is in a rectangular shape, and the cross section of the flipping claw is conical. When the mounting plate moves upward, the flipping claw contacts the mold bottom plate and drives the capsule mold to move upward. During the upward movement of the capsule mold, the mold pin of the capsule mold rotates around the longitudinal guide plate of the hollow capsule mold feeder and slides and rubs relative to the longitudinal guide plate. As the flipping claw continues to move upward, that is, when the flipping claw is fully ejected, the capsule mold completes a 90-degree flip, that is, the mold pin is placed horizontally on the longitudinal guide plate, and then, it is pushed to the demoulding device of the hollow capsule by the pushing device of the hollow capsule mold feeder for demoulding.

Similarly, words such as "one" or "a" do not indicate a quantity limitation, but indicate the existence of at least one.

[0028] like Figure 1-6 As shown, as an embodiment of the utility model, a capsule mold flipping structure 100 is disclosed, which is used to flip a capsule mold 200, and the capsule mold 200 includes a strip 201 and a plurality of capsule core rods 202 arranged along the length direction of the strip 201. The capsule mold flipping structure 100 includes a flip shaft 1 connected to an external driving structure and at least one flip disk 2 arranged coaxially with the flip shaft 1. The flip shaft 1 is arranged parallel to the strip 201, and the flip disk 2 includes an intermediate body 21 fixed relative to the flip shaft 1 and a plurality of flip bodies 22 connected to the peripheral side of the intermediate body 21 in the circumferential direction, and the flip disk 2 can rotate with the rotation of the flip shaft 1. The two adjacent flip bodies 22 are arranged at intervals to form a positioning groove 23 that can accommodate the capsule mold 200 and allow the capsule mold 200 to move along the length direction of the flip axis 1. The capsule mold 200 in the positioning groove 23 can move relative to the positioning groove 23 along the length direction of the flip axis 1, so as to facilitate the external pushing structure to push the capsule mold 200 to the core rod oiling device, or to push the capsule mold 200 with the semi-finished product to the capsule semi-finished product demoulding device. The two flip bodies 22 on both sides of the positioning groove 23 are provided with a first limiting member 24 and a second limiting member 25 arranged oppositely. The second limiting member 25 is arranged at intervals on the outside of the first limiting member 24 and can telescopically move between a closed state extending into the positioning groove 23 and an open state retracted into the flip body 22. When the second limiting member 25 is in the closed state, the two sides of the strip 201 can be respectively limited in the limiting groove 26 formed by the side walls of the two flip bodies 22 and the first limiting member 24 and the second limiting member 25. Since the capsule mold flipping structure 100 of the present embodiment is provided with a flipping disk 2, the two sides of the strip 201 can be respectively limited in the limiting grooves 26 formed by the side walls of the two flipping bodies 22 and the first limiting member 24 and the second limiting member 25. That is to say, the two sides of the strip 201 are respectively stuck in the two limiting grooves 26 and cannot rotate. The flipping shaft 1 drives the flipping disk 2 to rotate under the drive of the external channel structure, thereby driving the capsule mold 200 to flip 90° as a whole. Compared with the flipping structure of the prior art, the capsule core rod 202 or the semi-finished capsule does not need to be worn during the flipping process of the utility model, so it is more conducive to the reuse of the capsule mold 200, and is also more conducive to ensuring the integrity of the semi-finished capsule, thereby improving the yield rate. In addition, a plurality of positioning grooves 23 are formed on the flipping disk 2. As the flipping disk 2 rotates, a plurality of capsule molds 200 can be continuously flipped, and the flipping efficiency is high. In addition, the second limiting member 25 can telescopically move between a closed state in which it extends into the positioning groove 23 and an open state in which it is retracted into the flip body 22 , which is beneficial for arranging the two sides of the strip 201 in the two limiting grooves 26 , respectively.

[0029] like Figure 2As shown, in some specific embodiments, the positioning groove 23 is arranged along the radial direction of the flip plate 2, so that the flip angle of the capsule mold 200 in the positioning groove 23 is the same as the rotation angle of the flip plate 2, which is convenient for controlling the flip angle of the flip plate 2. A slide groove 2210 arranged perpendicular to the positioning groove 23 is provided in the flip body 22, and the second stopper 25 is arranged in the slide groove 2210 and slidably connected to the slide groove 2210. One end of the slide groove 2210 is provided with a notch connected to the positioning groove 23, and one end of the second stopper 25 can pass through the notch and extend into the positioning groove 23.

[0030] like Figure 4 As shown, in some specific embodiments, the flip body 22 includes a flip main body 221 and a flip cover body 222 stacked on one side of the flip main body 221, and the slide groove 2210 is formed by being recessed inward from one side of the flip main body 221 close to the flip cover body 222. The flip cover body 222 is detachably connected to the flip main body 221 to facilitate the installation, disassembly or replacement maintenance of the second limit member 25 in the slide groove 2210. After connection, the flip cover body 222 covers the slide groove 2210 to prevent the second limit member 25 from detaching from the slide groove 2210.

[0031] like Figure 5 As shown, in some specific embodiments, the slide groove 2210 includes a first slide groove 2211 arranged perpendicular to the positioning groove 23 and a second slide groove 2212 arranged at an angle to and connected to the first slide groove 2211. The second stopper 25 includes a telescopic portion 251 and a stopper 252 connected to one end of the telescopic portion 251 at an angle, the telescopic portion 251 is arranged in the first slide groove 2211 and is slidably connected to the first slide groove 2211, and the stopper 252 is arranged in the second slide groove 2212 and is slidably connected to the second slide groove 2212. When the limiting portion 252 abuts against a side wall of the second sliding groove 2212 close to the positioning groove 23, one end of the telescopic portion 251 away from the limiting portion 252 extends into the positioning groove 23, so that the second limiting member 25 is in a closed state, thereby preventing the strip 201 in the limiting groove 26 from falling off the flip plate 2; when the limiting portion 252 abuts against a side wall of the second sliding groove 2212 away from the positioning groove 23, one end of the telescopic portion 251 away from the limiting portion 252 retracts into the first sliding groove 2211, so that the second limiting member 25 is in an open state, thereby allowing the strip 201 to extend into the limiting groove 26. In this embodiment, the first sliding groove 2211 is arranged vertically with the second sliding groove 2212, and correspondingly, the telescopic portion 251 is arranged vertically with the limiting portion 252, so that the second limiting member 25 is in stable contact and limiting with the sliding groove 2210.

[0032] In some specific embodiments, a reset member (not shown in the figure) is arranged between the side of the telescopic portion 252 away from the positioning groove 23 and the flip body 221. The reset member can be a structure with elastic reset ability such as a spring, elastic silicone, etc., which can provide a force to keep the limiting portion 252 in contact with a side wall of the second sliding groove 2212 close to the positioning groove 23, thereby keeping the second limiting member 25 in a closed state, and allowing the second limiting member 25 to switch to an open state under the pressure during the process of the strip 201 extending into the positioning groove 23, and automatically reset to a closed state after the strip 201 extends into the positioning groove 23. Of course, in other embodiments, the reset member can also be arranged between the side of the limiting portion 252 away from the positioning groove 23 and the flip body 221, or simultaneously arranged between the telescopic portion 251 and the side of the limiting portion 252 away from the positioning groove 23 and the flip body 221, which can also achieve a reset effect.

[0033] like Figure 5 As shown, in some specific embodiments, a first mounting groove 2511 is provided on the telescopic portion 251, which is recessed from one end surface away from the positioning groove 23 toward the direction close to the positioning groove 23; a second mounting groove 2214 is recessed from one side wall away from the positioning groove 23 toward the direction away from the positioning groove 23 on the first sliding groove 2211; the second mounting groove 2214 is arranged corresponding to the first mounting groove 2511; one end of the reset member is installed in the first mounting groove 2511, and the other end is installed in the second mounting groove 2214, so as to facilitate the assembly and positioning of the reset member.

[0034] like Figure 4 As shown, in some specific embodiments, a first connecting channel 2215 is provided on the flip body 221, and a second connecting channel 2221 arranged corresponding to the first connecting channel 2215 is penetrated through the flip cover body 222. The flip cover body 222 and the flip body 221 are detachably connected in the first connecting channel 2215 and the second connecting channel 2221 arranged correspondingly by fasteners. The fasteners may be structures such as screws, bolts, and pins.

[0035] like Figure 4 As shown, in some specific embodiments, the intermediate body 21 includes an intermediate main body 211 and an intermediate cover body 212 stacked on one side of the intermediate main body 211. The intermediate main body 211 is integrally formed with each flip main body 221, and the intermediate cover body 212 is integrally formed with each flip cover body 222. The structure is simple and stable, which facilitates the rapid assembly or disassembly of the flip plate 2.

[0036] like Figure 3As shown, in some specific embodiments, a first guide surface 223 arranged at an angle to the positioning groove 23 is provided at one end of the side wall of the flip body 22 away from the flip axis 1, and the distance between the two first guide surfaces 223 on two adjacent flip bodies 22 gradually increases from the end close to the flip axis 1 to the end away from the flip axis 1, so as to facilitate guiding the capsule mold 200 to extend into the positioning groove 23. An end surface of the second stopper 25 close to the positioning groove 23 is provided as a second guide surface 2512 arranged at an angle to the positioning groove 23, and the distance between the two second guide surfaces 2512 on two adjacent flip bodies 22 gradually increases from the end close to the flip axis 1 to the end away from the flip axis 1, so as to facilitate guiding the strip plate 201 to extend into the limit groove 26. When the second stopper 25 is in the closed state, the distance between the ends of the two second guide surfaces 2512 away from the turning axis 1 is equal to the distance between the ends of the two first guide surfaces 223 close to the turning axis 1, ensuring that the strip 201 can smoothly transition to the second guide surface 2512 after passing through the first guide surface 223. In other embodiments, the distance between the ends of the second guide surface 2512 away from the turning axis 1 can also be set to be greater than the distance between the ends of the two first guide surfaces 223 close to the turning axis 1, which also has the same effect. In this embodiment, when the second stopper 25 is in the closed state, the end of the second guide surface 2512 away from the turning axis 1 is combined with the end of the first guide surface 223 close to the turning axis 1, so that the second guide surface 2512 and the first guide surface 223 transition smoothly, which is conducive to guiding the strip 201 to the limiting groove 26 via the first guide surface 223 and the second guide surface 2512 in sequence.

[0037] like Figure 3 , 6 As shown, in some specific embodiments, a capsule semi-finished product is formed at the free end of the capsule core rod 202, and a first limiting member 24 protrudes from the side wall of the flip body 22 toward the positioning groove 23. A capsule channel 27 for accommodating the capsule semi-finished product and for the capsule semi-finished product to move along the length direction of the flip axis 1 is formed between one end of the positioning groove 23 close to the flip axis 1 and two first limiting members 24 on the flip body 22 on both sides of the positioning groove 23. A core rod channel 28 for accommodating the capsule core rod 202 and for the capsule core rod 202 to move along the length direction of the flip axis 1 is formed between the two first limiting members 24 on the flip body 22 on both sides of the positioning groove 23. The semi-finished capsule can pass through the core rod channel 28 and extend into the capsule channel 27, and the rubber plate 201 can move relative to the limiting groove 26 along the length direction of the flip axis 1, so that the capsule mold 200 or the capsule mold 200 with the capsule semi-finished product can move relative to the positioning groove 23 along the length direction of the flip axis 1.

[0038] like Figure 6As shown, in some specific embodiments, eight positioning grooves 23 are provided, and the eight positioning grooves 23 are evenly spaced along the circumferential direction of the flip plate 2, that is, the angle between two adjacent positioning grooves 23 is 45°, and the angle of the flip shaft 1 and the flip plate 2 rotating by one stroke is 45°. After the capsule mold 200 is installed in the positioning groove 23, it can be flipped 90° after the flip shaft 1 and the flip plate 2 rotate by two strokes, that is, the capsule mold 200 is flipped from a horizontal state to a vertical state. When flipping multiple capsule molds 200 continuously, the flip shaft 1 and the flip plate 2 can drive the previous capsule mold 200 to rotate by one stroke. The capsule mold 200 flips to 90°, and at the same time drives the subsequent capsule mold 200 to flip to 45°, and the angle of each rotation of the flip shaft 1 and the flip disk 2 is 45°. Compared with only four positioning grooves 23, when multiple capsule molds 200 are flipped continuously, the flip shaft 1 and the flip disk 2 only flip one capsule mold to 90° each time they rotate a stroke, and the angle of each rotation of the flip shaft 1 and the flip disk 2 is 90°. The flipping speed of this embodiment is faster and the continuous flipping efficiency is higher. Of course, in other embodiments, the positioning groove 23 can also be set to four or other numbers.

[0039] In some specific embodiments, two flipping disks 2 are provided, and the two flipping disks 2 are arranged at an interval. The same capsule mold 200 is flipped by the two flipping disks 2 at the same time, which improves the stability during the flipping process and is conducive to the smooth flipping of the capsule mold 200. In other embodiments, only one flipping disk 2 or another number of flipping disks 2 can be provided, all of which can be used to flip the capsule mold 200.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the utility model.

[0041] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
