Description

Technical Field

[0001] This utility model relates to the field of soft capsule production, specifically a rolling soft capsule forming device. Background Technology

[0002] When producing soft capsules using a roller mold soft capsule forming device, gelatin and other capsule materials are first made into a liquid. The liquid is then transported to a cartridge above the roller mold. At the same time, the drug or contents are prepared into a uniform liquid or semi-solid state. During the production process, the roller mold begins to rotate, and the liquid in the cartridge forms a uniform film covering the surface of the roller mold through small holes in the nozzle. Then, the contents are precisely injected into the film between the two roller molds using a metering pump. The continuous rolling of the roller mold causes the film to encapsulate the contents and complete the formation of the soft capsule.

[0003] Chinese patent CN205108412U discloses a roller-type soft capsule pelleting machine, belonging to the field of soft capsule pelleting equipment. It includes a machine head, a machine body, a feeding system, and a forming system. The machine head and machine body are located on the lower layer. The machine head is connected to the material tank on the upper layer through a feeding pipe. The forming system includes a spray body and a first mold and a second mold located below the spray body. The spray body is composed of a front cover, a spray body body, and a rear cover. The front cover is provided with a first water inlet and a second water inlet. The lower part of the spray body body has a first main channel on one side and a second main channel on the other side. The rear cover is provided with a first auxiliary channel, a second auxiliary channel, a first water outlet, and a second water outlet. The two water channels are respectively connected to an external constant temperature water tank to form two circulating water channels.

[0004] The aforementioned patents eliminate the need for manual material handling, saving labor and ensuring uniform heating of the sprayed material, thus improving product yield. However, they cannot quickly separate the soft capsules from the waste rubber, nor can they effectively solve the problem of soft capsules sticking to the internal grooves of the roller mold. Therefore, this utility model proposes a roller mold soft capsule forming device. Utility Model Content

[0005] The purpose of this invention is to provide a roller-type soft capsule forming device, which can effectively separate waste rubber from soft capsules by setting two material separating rods, thereby improving the material sorting efficiency in the production process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roller-type soft capsule forming device, comprising two pairs of supports, with forming rollers rotatably connected between each pair of supports; gears are rotatably connected to the sides and tops of the two supports on one side; several circular grooves are formed on the outer surfaces of the two forming rollers; a material box is provided between the tops of the two forming rollers; connecting plates are fixedly connected between the two supports on one side and between the two supports on the other side; and two material distribution rods are rotatably connected between the two connecting plates located between the bottoms of the two forming rollers.

[0007] Preferably, a waste bin is placed between the two connecting plates and between the two distributing rods, and storage bins are placed between the two pairs of supports and at the front and rear of the waste bin. A guide plate is inclinedly and fixedly connected between the two pairs of supports and between the storage bin and the distributing rod.

[0008] Preferably, one end of each of the two material distribution rods is fixedly connected to a gear 2 through the side of a connecting plate on one side, and the two gears 2 mesh with each other. A motor 2 is fixedly connected to the side of the connecting plate on the other side, and the output shaft of the motor 2 passes through the side of the connecting plate on the other side and is fixedly connected to the other end of one of the material distribution rods.

[0009] Preferably, a motor is fixedly connected to the side of the bracket at the rear of the other side, and the output shaft of the motor passes through the side of the bracket and is fixedly connected to the side of the forming mold at the rear.

[0010] Preferably, a rotating rod is rotatably connected between the two pairs of brackets and at the bottom of the two forming dies, and bristles are fixedly connected to the outer surface of the rotating rod, with the bristles in contact with the circular groove.

[0011] Preferably, one end of each of the two rotating rods passes through the side of the two supports on one side, and one end of each of the two rotating rods is fixedly connected to a pulley one, and the side of each of the two gears two is fixedly connected to a pulley two, with a belt sleeved between the pulley one and the pulley two.

[0012] Preferably, a pair of fixing blocks are fixedly connected to the front and rear of each pair of brackets, and a baffle is rotatably connected between the pair of fixing blocks. Two springs are fixedly connected between the rear of the baffle and the front of the bracket, and the bottom of the rear of the baffle contacts the front of the storage box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) By setting two separating rods, not only can waste rubber and soft capsules be effectively separated, improving the material sorting efficiency in the production process, but it also provides convenience for the subsequent collection of soft capsules and the treatment of waste rubber. This separation method is simple and efficient, greatly reducing the workload of manual screening and lowering production costs.

[0015] 2) Since the two dispensing rods are not stationary, they can interact dynamically with the soft capsules through their own rotation during the descent. This dynamic interaction can not only quickly push the soft capsules to the direction of the guide plate to achieve efficient dispensing, but also prevent the soft capsules from being damaged by excessive impact during the impact.

[0016] 3) By setting up a rotating rod in conjunction with brush bristles, the problem of soft capsules potentially sticking to the circular groove of the molding die during the molding process is cleverly solved. The rotation of the rotating rod drives the brush bristles to clean the circular groove. This mechanical cleaning method is simple and effective, and can remove the sticky soft capsules in a timely and thorough manner, reducing production losses caused by sticking.

[0017] 4) By setting up baffles, a safety barrier is provided for the entire production process. The baffles can effectively prevent the soft capsules swept off by the brushes from flying out of the device, ensuring the cleanliness and safety of the production environment. At the same time, the presence of the baffles ensures that the soft capsules can only fall to the top of the guide plate, thus smoothly entering the storage box, further standardizing the movement trajectory of the soft capsules and improving the orderliness and controllability of the production process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Combination Figure 1 - Figure 5 A soft capsule forming device with a roller pattern includes two pairs of supports 1, with forming rollers 2 rotatably connected between each pair of supports 1. Gears 3 are rotatably connected to the sides and tops of the two supports 1 on one side. Several circular grooves 5 are formed on the outer surfaces of the two forming rollers 2. A material box 4 is provided between the tops of the two forming rollers 2. Connecting plates 7 are fixedly connected between the two supports 1 on one side and between the two supports 1 on the other side. Two material distribution rods 8 are rotatably connected between the two connecting plates 7 and the bottoms of the two forming rollers 2. The distance between the two material distribution rods 8 is less than the width of the soft capsule.

[0027] In actual operation, the material box 4 is fixedly connected to the frame of the overall soft capsule forming device. Two gelatin sheets 21, formed by the cooling of gelatin liquid, pass over the outer surfaces of the two forming molds 2. The starting motor 6 drives one of the forming molds 2 to rotate counterclockwise, which in turn, through the meshing of two gears 3, drives the other forming mold 2 to rotate clockwise. This causes the two gelatin sheets 21 to mesh and compress each other. Then, the material required for the soft capsule is injected between the two gelatin sheets 21 through the material box 4. Finally, the two rotating forming molds 2... The process involves using several circular grooves 5 to combine two rubber sheets 21 containing material into one rubber sheet 21, which is then cut into several soft capsules. After the soft capsules are formed, they fall down, and the cut rubber sheets 21, which are considered waste rubber sheets, also fall down. During their fall, the soft capsules collide with two separating rods 8. Since the distance between the two separating rods 8 is less than the width of the soft capsule, it cannot pass between the two separating rods 8 and fall down. Instead, the waste rubber sheets fall down between the two separating rods 8, thus achieving the purpose of quickly separating the waste rubber sheets from the soft capsules.

[0028] See Figure 3 A waste bin 10 is placed between the two connecting plates 7 and between the two material distribution rods 8. A storage bin 11 is placed between the two pairs of supports 1 and at the front and rear of the waste bin 10. A guide plate is inclinedly and fixedly connected between the two pairs of supports 1 and between the storage bin 11 and the material distribution rod 8.

[0029] Specifically, the soft capsules blocked by the two dispensing rods 8 will enter the interior of the two storage bins 11 along the two guide plates, while the waste rubber will descend between the two dispensing rods 8 and enter the interior of the waste bin 10.

[0030] See Figure 3 and Figure 4 One end of each of the two material distribution rods 8 passes through the side of the connecting plate 7 on one side and is fixedly connected to a gear 9. The two gears 9 mesh with each other. A motor 20 is fixedly connected to the side of the connecting plate 7 on the other side. The output shaft of the motor 20 passes through the side of the connecting plate 7 on the other side and is fixedly connected to the other end of one of the material distribution rods 8.

[0031] Specifically, starting motor 20 drives one of the distributing rods 8 to rotate clockwise, and then through the meshing of two gears 2 9, drives the other distributing rod 8 to rotate counterclockwise, thus making the distributing rods 8 rotate synchronously. When the soft capsule descends and collides with the two distributing rods 8, the rotation of the two distributing rods 8 will quickly bounce the soft capsule to the front and rear, and then make contact with the two guide plates. Therefore, the distributing rods 8 can rotate when the soft capsule falls, which greatly improves the distributing efficiency.

[0032] See Figure 2 and Figure 3 A motor 6 is fixedly connected to the side of the bracket 1 at the rear of the other side. The output shaft of the motor 6 passes through the side of the bracket 1 and is fixedly connected to the side of the forming mold 2 at the rear.

[0033] See Figure 3 A rotating rod 12 is rotatably connected between the two pairs of brackets 1 and at the bottom of the two forming rollers 2. Brush bristles 13 are fixedly connected to the outer surface of the rotating rod 12, and the brush bristles 13 are in contact with the circular groove 5.

[0034] Specifically, when the molding roller 2 cuts the rubber 21 into soft capsules, a small number of soft capsules will adhere to the inside of the round groove 5. At this time, the rotating rod 12 is rotated, causing the brush bristles 13 to rotate as well. Since the brush bristles 13 are in contact with the round groove 5, when the rotating rod 12 rotates and drives the brush bristles 13 to rotate as well, the soft capsules adhering to the inside of the round groove 5 will be swept off, thereby preventing the soft capsules from adhering to the inside of the round groove 5.

[0035] See Figure 3 and Figure 4 One end of each of the two rotating rods 12 passes through the side of the two brackets 1 on one side, and one end of each of the two rotating rods 12 is fixedly connected to a pulley 14. The sides of the two gears 9 are fixedly connected to pulleys 15. A belt 16 is sleeved between pulley 14 and pulley 15.

[0036] Specifically, the rotation of the two gears 9 drives the two pulleys 15 to rotate together, which in turn drives the two pulleys 14 to rotate together via the two belts 16, and in turn drives the two rotating rods 12 to rotate together.

[0037] See Figure 4 Each pair of brackets 1 has a pair of fixing blocks 17 fixedly connected to its front and rear. A baffle 18 is rotatably connected between the pair of fixing blocks 17. Two springs 19 are fixedly connected between the rear of the baffle 18 and the front of the bracket 1. The bottom of the rear of the baffle 18 is in contact with the front of the storage box 11.

[0038] Specifically, when the brush bristles 13 sweep the soft capsules inside the circular groove 5, the baffle 18 prevents the soft capsules from flying out of the device and they can only fall to the top of the guide plate.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
