[0003] However, the existing technology still has the following shortcomings: conventional soft capsule feeders mostly use vibration or mechanical pushing to feed, which are effective for materials with regular shapes and not easy to stick together. However, for soft capsules with oval shapes and easy to stick together, these traditional methods easily cause the capsules to break and stick together, affecting the feeding efficiency and product quality. Summary of the invention

[0006] Preferably, the capsule arranger is fitted to the bottom of the capsule arranger and rotates below the capsule arranger to receive capsules for unloading, and the fitting and docking method ensures that the capsules can fall into the groove smoothly and orderly.

[0007] Preferably, the capsule arranger is provided with a rotatable roller brush and an arrangement groove inside, wherein the surface of the roller brush is provided with five scrapers made of soft silicone material, and the scrapers are attached to the surface of the arrangement groove, wherein an arrangement discharge port is provided at the bottom of the capsule arranger, wherein the discharge port and the arrangement groove correspond to each other, and are used to guide the soft capsules out of the silo and perform preliminary arrangement, ensuring that the capsules are arranged one by one to avoid overlapping and adhesion, and preparing for subsequent negative pressure suction.

[0008] Preferably, a discharge port is provided at the bottom of the silo, wherein the discharge port is connected to the interior of the capsule arranger, and a discharge regulating device is provided inside the discharge port for adjusting the outflow speed and quantity of the capsules to meet the needs of subsequent processes. The design of the silo ensures that the soft capsules will not be subjected to excessive mechanical pressure during the discharge process to avoid breakage.

[0009] Preferably, the surface of the negative pressure roller is provided with distributed cavities, and the cavities correspond to the feeding openings, so that the soft capsules are adsorbed on the inner wall of the cavities when feeding.

[0010] Preferably, a driving assembly is provided inside the control box, and the driving assembly is provided with two sets of output shafts, wherein the roller brush and the negative pressure roller are respectively fixed on the surface of the output shaft for driving the negative pressure roller and the roller brush to rotate.

[0025] See also Figure 1-4The present invention provides a technical solution: a negative pressure soft capsule feeder, comprising an equipment base 1, a control box 2, a touch screen 3, a silo 4, a capsule arranger 5 and a negative pressure roller 6, wherein the control box 2 is fixedly connected to the top of the equipment base 1, a driving assembly is arranged inside the control box 2, and the driving assembly is provided with two sets of output shafts, wherein a roller brush 51 and a negative pressure roller 6 are respectively fixed on the surface of the output shaft, and are used to drive the negative pressure roller 6 and the roller brush 51 to rotate, the touch screen 3 is fixedly connected to the side of the control box 2, the silo 4 is fixedly connected to the top of the equipment base 1 and the top of the capsule arranger 5, and the bottom of the silo 4 A discharge port is provided, wherein the discharge port is connected to the interior of the capsule arranger 5, and a discharge regulating device is provided inside the discharge port for adjusting the outflow speed and quantity of the capsules to meet the needs of subsequent processes. The design of the silo 4 ensures that the soft capsules will not be subjected to excessive mechanical pressure during the unloading process to avoid damage. The capsule arranger 5 is fixedly connected to the side of the control box 2, and the capsule arranger 5 is fitted to the bottom of the capsule arranger 5 and is located below the capsule arranger 5 for rotation, and is used to receive capsules for unloading. The fitting and docking method ensures that the capsules can fall into the groove smoothly and orderly. The capsule arranger 5 is provided with a rotatable The roller brush 51 and the arrangement groove 52 are provided with five scrapers made of soft silicone material on the surface of the roller brush 51, and the scrapers are attached to the surface of the arrangement groove 52. The capsule arranger 5 is provided with an arranged discharge port below, and the discharge port corresponds to the arrangement groove 52, which is used to guide the soft capsules out of the silo 4 and arrange them preliminarily, ensuring that the capsules are arranged one by one to avoid overlapping and adhesion, so as to prepare for the subsequent negative pressure absorption. The negative pressure roller 6 is rotatably connected to the side of the control box 2, and the surface of the negative pressure roller 6 is provided with distributed and arranged cavities 61, and the cavities 61 correspond to the discharge port. When unloading, the soft capsule is adsorbed on the inner wall of the cavity 61. A negative pressure structure is arranged inside the negative pressure roller 6, wherein the cavity 61 is provided with air holes. The air holes and the negative pressure structure are connected through negative pressure airways. The soft capsule is gently sucked and transported through negative pressure adsorption. When the soft capsule falls into the cavity 61 of the negative pressure roller 6, the negative pressure system is started to form a negative pressure area in the cavity 61. The soft capsule is adsorbed on the inner wall of the cavity 61. As the negative pressure roller 6 rotates, the soft capsule is conveyed to the bottom, and then the soft capsule is blown off by positive pressure, so that the soft capsule can accurately fall into the blister, thereby entering the next step of the process.

[0026] In actual operation, when this device is used, first, the soft capsules stored in the silo 4 move to the bottom discharge port under the action of gravity, and the discharge regulating device accurately adjusts the outflow speed and quantity of the capsules according to the requirements of the subsequent process to ensure a stable supply and avoid damage to the capsules due to excessive outflow or excessive outflow. Then, the capsules enter the capsule arranger 5, and the rotatable roller brush 51 inside the arranger starts to work. The five scrapers on its surface are made of soft silicone material. During the rotation of the roller brush, they gently contact the surface of the arrangement groove 52, gradually combing the capsules and orderly guiding them to the discharge port corresponding to the arrangement groove 52, so as to achieve the preliminary arrangement of the capsules and ensure that the capsules are neatly arranged one by one, effectively preventing overlapping and adhesion. Subsequently, the negative pressure roller 6 continues to rotate, and when the cavity 61 on the surface of the roller rotates to a position corresponding to the discharge port, the negative pressure structure inside the negative pressure roller 6 starts. The negative pressure roller 61 is moved, and a negative pressure area is quickly formed in the cavity 61 through the connection between the negative pressure airway and the air holes inside the cavity 61. At this time, the soft capsule dropped from the discharge port is gently and firmly adsorbed on the inner wall of the cavity 61 under the action of the negative pressure suction force. With the stable rotation of the negative pressure roller 6, the cavity 61 adsorbing the soft capsule is gradually transferred to a specific position. Finally, when it reaches the specified position, the positive pressure system works to blow gas into the cavity 61, so that the soft capsule is separated from the adsorption of the cavity 61 under the action of the positive pressure and falls accurately into the blister, thereby smoothly entering the next step of the production process. During the whole process, the driving component inside the control box 2 provides power for the rotation of the roller brush 51 and the negative pressure roller 6, and the touch screen 3 can facilitate the operator to accurately adjust various parameters of the equipment according to the actual production situation, such as the discharge speed, the roller speed, etc., so as to realize efficient and accurate soft capsule feeding operation.
