Description

Technical Field

[0001] This utility model relates to the technical field of fully automatic hard capsule filling machines, specifically to a capsule dispensing device for a fully automatic hard capsule filling machine. Background Technology

[0002] The fully automatic hard capsule filling machine is a device used to fill powdered, granular, or liquid materials into empty capsules. It is widely used in the pharmaceutical, health product, and food industries. It can automatically complete the processes of capsule arrangement, separation, filling, locking, and rejection, and features high precision, high efficiency, and high stability.

[0003] Chinese patent CN 214969186 U discloses a "capsule dispensing device for a fully automatic hard capsule filling machine". The device describes "pouring capsules from the feeding port into the storage bin, and the capsules falling into the capsule slots on the circular track through the feeding pipe. The feeding valve controls the number of capsules dispensed to prevent waste caused by blockage". However, in actual capsule dispensing, it is often necessary to dispense multiple capsules into each capsule slot at the same time. The feeding pipe is prone to congestion with a large number of capsules at once, which not only easily causes jamming, but also makes it difficult to accurately control the capsules falling one by one through the feeding valve, resulting in poor capsule dispensing effect. Utility Model Content

[0004] The purpose of this invention is to provide a capsule dispensing device for a fully automatic hard capsule filling machine. Through a material distribution mechanism composed of multiple sets of partition plates, arc-shaped baffles, and cover plates, multiple channels adapted to the size of the capsules can be formed. Combined with a conveyor belt, the capsules can be sequentially arranged and moved into each channel, thereby further vertically guiding the capsules from each channel into the corresponding capsule cylinder below. This effectively sorts and arranges the capsules, ensuring they are sequentially placed into each capsule cylinder, avoiding material jamming and greatly guaranteeing the dispensing effect, thus solving the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a capsule dispensing device for a fully automatic hard capsule filling machine, comprising:

[0006] A fixed frame, on the inner side of which a conveyor belt is rotatably mounted;

[0007] The material distribution mechanism includes support frames symmetrically arranged at both ends of the top side of the fixed frame near the top of the conveyor belt. Multiple partition plates are fixed in an array on the inner side of the two support frames, and the partition plates are located at the top of the conveyor belt. Arc-shaped baffles are connected to the ends of the multiple partition plates near the conveyor belt.

[0008] The material guiding mechanism includes a capsule tube disposed between the bottom ends of two adjacent arc-shaped baffles. Each of the multiple capsule tubes has a sliding cavity inside, and a switch assembly is disposed at the bottom end of the capsule tube. A positioning assembly is disposed above the bottom end of the capsule tube near the switch assembly.

[0009] Preferably, the two outermost partition plates are symmetrically provided with guide plates at one end relative to the arc-shaped baffle, and the two guide plates are distributed at an outward tilt.

[0010] Preferably, a cover plate is provided between two adjacent arc-shaped baffles.

[0011] Preferably, the switch assembly includes a U-shaped support seat disposed on one side of the bottom end of the capsule, a cylinder is fixedly connected to the bottom side of the U-shaped support seat by a bracket, an L-shaped sealing plate is slidably connected between the bottom sides of the plurality of capsules, and the output end of the cylinder is connected to the L-shaped sealing plate.

[0012] Preferably, both ends of the L-shaped sealing plate are connected through limit rods, one end of the limit rod is fixedly connected to the capsule, and the other end of the limit rod is provided with a limit block.

[0013] Preferably, the positioning component includes a negative pressure pump fixedly connected to the top side of the U-shaped support seat via a bracket. The suction end of the negative pressure pump is connected to a connecting pipe via a pipeline. An air suction pipe is connected between the connecting pipe and the capsule near the top of the L-shaped sealing plate. One end of the air suction pipe is connected to the sliding cavity, and a solenoid valve is provided on the air suction pipe.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The material distribution mechanism, composed of multiple sets of partition plates, arc-shaped baffles, and cover plates, can form multiple channels adapted to the size of the capsules. In conjunction with the conveyor belt, the capsules can be arranged and moved into each channel in sequence. This allows the capsules in each channel to be vertically introduced into the corresponding capsule cylinder below, thus effectively sorting and arranging the capsules. This ensures that the capsules can be arranged and placed into each capsule cylinder in sequence, avoiding material jamming and greatly guaranteeing the capsule dispensing effect.

[0016] By setting up a guiding mechanism, which consists of multiple capsule cylinders, a switching assembly, and a positioning assembly, the positioning assembly generates suction to adsorb the capsules facing the suction tube port, thus fixing and limiting the capsules. At the same time, it can restrict the capsules arranged above. Meanwhile, the switching assembly controls the movement of the L-shaped sealing plate to switch the bottom end of the capsule cylinder. With the cooperation of both, the capsules arranged inside the capsule cylinder can be controlled to fall one by one, thereby accurately and efficiently controlling the number of capsules dispensed, greatly ensuring the accuracy of capsule dispensing and achieving good results.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-4 The capsule dispensing device of a fully automatic hard capsule filling machine shown includes:

[0026] A fixed frame 1 is provided, and a conveyor belt 2 is rotatably mounted on the inner side of the fixed frame 1.

[0027] The material distribution mechanism includes support frames 3 symmetrically arranged at both ends of the top side of the fixed frame 1 near the conveyor belt 2. Multiple partition plates 4 are fixed in an array on the inner side of the two support frames 3, and the partition plates 4 are located at the top of the conveyor belt 2. The ends of the multiple partition plates 4 are connected to arc-shaped baffles 6 on the side near the conveyor belt 2.

[0028] The two outermost partition plates 4 are symmetrically positioned with guide plates 5 at one end relative to the arc-shaped baffle 6, and the two guide plates 5 are inclined outwards. Based on this, the capsule can be guided by the guide plates 5, so that the capsule can smoothly enter between the partition plates 4.

[0029] A cover plate 8 is provided between two adjacent arc-shaped baffles 6. Based on this, the cover plate 8 can prevent the capsule from flying out between the two arc-shaped baffles 6.

[0030] By arranging multiple partition plates 4 in an array, multiple channels adapted to the size of the capsules can be formed. During use, the capsules can fall onto the conveyor belt 2, and with the cooperation of two guide plates 5, the capsules can be arranged sequentially into the channels formed by the partition plates 4. The capsules can move in the channels with the conveyor belt 2. When they reach the end, with the cooperation of multiple sets of arc-shaped baffles 6, the capsules in each channel can be further vertically introduced into the corresponding capsule cylinders 7 below, thereby effectively sorting and arranging the capsules so that they can be arranged sequentially into each capsule cylinder 7, avoiding material jamming and greatly ensuring the capsule dispensing effect.

[0031] The material guiding mechanism includes a capsule 7 located between the bottom ends of two adjacent arc-shaped baffles 6. Each capsule 7 has a sliding cavity 9 inside, and a switch assembly is located at the bottom end of the capsule 7. A positioning assembly is located above the bottom end of the capsule 7 near the switch assembly.

[0032] The switch assembly includes a U-shaped support 10 located on one side of the bottom of the capsule 7. A cylinder 11 is fixedly connected to the bottom of the U-shaped support 10 via a bracket. An L-shaped sealing plate 12 is slidably connected between the bottom sides of multiple capsules 7. The output end of the cylinder 11 is connected to the L-shaped sealing plate 12.

[0033] Both ends of the L-shaped sealing plate 12 are connected to limiting rods 13. One end of the limiting rod 13 is fixedly connected to the capsule 7, and the other end of the limiting rod 13 is provided with a limiting block 14. Based on this, by setting the limiting rod 13 and the limiting block 14, the L-shaped sealing plate 12 can move stably along a straight line.

[0034] The positioning assembly includes a negative pressure pump 18 fixedly connected to the top side of the U-shaped support base 10 via a bracket. The suction end of the negative pressure pump 18 is connected to a connecting pipe 17 via a pipe. An air suction pipe 15 is connected between the connecting pipe 17 and the capsule 7 near the top of the L-shaped sealing plate 12. One end of the air suction pipe 15 is connected to the sliding cavity 9, and a solenoid valve 16 is provided on the air suction pipe 15.

[0035] By activating the negative pressure pump 18 and connecting the pipes 17, suction is generated in each suction pipe 15. The suction pipe 15 is opened by the solenoid valve 16, which adsorbs the capsules facing the port of the suction pipe 15, thus fixing and limiting the capsules. At the same time, it can restrict the capsules arranged above. Then, the cylinder 11 drives the L-shaped sealing plate 12 to move, so that the L-shaped sealing plate 12 opens the bottom of the capsule cylinder 7. At this time, the capsule at the bottom of the capsule cylinder 7 can fall into the capsule plate groove set in advance below, while the capsules above it remain stationary due to adsorption and limitation. Then, the L-shaped sealing plate 12 can be controlled to reset and close the capsule cylinder 7. Then, the solenoid valve 16 closes the contact adsorption, allowing the arranged capsules to fall in sequence. When the capsules slide to the bottom, they are blocked by the L-shaped sealing plate 12, and the solenoid valve 16 can be opened again to adsorb the capsules above. By repeating the above steps, the number of capsules can be accurately and efficiently controlled, greatly ensuring the accuracy of capsule dispensing and achieving good results.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
