The adding roller is rotatable and has multiple circumferentially arranged suction ports on its outer circumferential surface. Multiple circumferentially arranged negative pressure channels, each connected to a corresponding suction port, are arranged within the adding roller. The input ports of the multiple negative pressure channels are arranged circumferentially around the axis of the adding roller. The negative pressure assembly includes a distribution block and a negative pressure source. The distribution block is fixedly arranged and forms an arc-shaped air groove opposite to the input port of the negative pressure channel. The negative pressure source is connected to the arc-shaped air groove to provide negative pressure to the arc-shaped air groove. The hopper stores and provides popping beads to the suction ports on the outer circumferential surface of the adding roller. When the adding roller rotates, the negative pressure in the negative pressure channel opposite the input port and the arc-shaped air groove creates negative pressure, causing the corresponding suction port to absorb the popping beads. The negative pressure in the negative pressure channel offset from the input port and the arc-shaped air groove disappears, causing the popping beads from the corresponding suction port to fall onto the sanitary product.

Description

Technical Field

[0001] This utility model relates to a bursting bead adding device for adding bursting beads to hygiene products. Background Technology

[0002] As is widely known, flavor capsules, also called pods, are pop-able beads that release a bursting sensation when squeezed. Primarily used in cigarette filters, they are small liquid beads embedded within the tobacco filter, encapsulating different types of flavoring liquids. Smokers can squeeze the bead during smoking to release the liquid, enriching the flavor and providing a more comfortable experience. Of course, the bead must be popped manually with fingers, teeth, or pod-popping pliers, and the timing of the popping is up to personal preference. To incorporate flavor capsules into sanitary products, disinfectants, fragrances, and other suitable liquids can be added as needed, giving the products antibacterial and fragrance properties. For example, adding flavor capsules to sanitary napkins prevents the disinfectants and fragrances from dissipating before use. Currently, equipment for adding flavor capsules to sanitary products is complex and expensive. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a simple device for adding popping beads.

[0004] A device for adding popping beads to sanitary products is characterized by comprising an adding roller, a hopper, and a negative pressure assembly. The adding roller is rotatable and has multiple circumferentially arranged suction ports on its outer circumferential surface. Multiple circumferentially arranged negative pressure channels, each connected to a corresponding suction port, are arranged within the adding roller. The input ports of the multiple negative pressure channels are arranged circumferentially around the axis of the adding roller. The negative pressure assembly includes a distribution block and a negative pressure source. The distribution block is fixedly arranged and forms an arc-shaped air groove opposite to the input port of the negative pressure channel. The negative pressure source is connected to the arc-shaped air groove to provide negative pressure to the arc-shaped air groove. The hopper stores and provides popping beads to the suction ports on the outer circumferential surface of the adding roller. When the adding roller rotates, the negative pressure in the negative pressure channel opposite to the arc-shaped air groove creates negative pressure, causing the corresponding suction port to absorb the popping beads. The negative pressure in the negative pressure channel offset from the input port and the arc-shaped air groove disappears, causing the popping beads from the corresponding suction port to fall onto the sanitary product.

[0005] In the above solution, when the roller rotates, the negative pressure channel opposite the inlet and the arc-shaped air groove forms a negative pressure, which causes the corresponding suction port to adsorb the popping beads. When the negative pressure of the negative pressure channel that is offset from the inlet and the arc-shaped air groove disappears, the popping beads of the corresponding suction port fall onto the sanitary products. The above solution has a simple structure and can efficiently add popping beads to sanitary products.

[0006] The negative pressure channel extends along the axial direction of the adding roller and the inlet is located on the end face of the adding roller. The distribution block is arranged opposite to the end face of the adding roller. The negative pressure channel is connected to the suction port through a branch channel extending radially along the adding roller. In this way, the fixedly arranged distribution block will not affect the normal operation of the adding roller and can ensure reliable communication between the inlet and the arc-shaped air groove.

[0007] The side of the hopper is closed by the outer peripheral surface of the adding roller, so that the popping beads in the hopper come into contact with the outer peripheral surface of the adding roller and are adsorbed by the suction port. This structure ensures that the suction port and the popping beads are in full contact, and that each suction port can effectively pick up the popping beads.

[0008] The hopper is at least partially made of transparent material to allow observation of the material level.

[0009] The hopper includes a hopper wall that is in contact with the outer peripheral surface of the adding roller. The hopper wall is made of an elastic material, such as silicone or rubber. Since the hopper is fixedly installed, the use of an elastic material for the hopper wall can ensure a reliable closed connection between the rotating adding roller and the hopper, preventing the bursting beads from leaking.

[0010] The dispensing block is circular and has a clearance notch extending radially therein to avoid the shaft of the adding roller.

[0011] The negative pressure assembly also includes an air suction hood. The negative pressure source is connected to the arc-shaped air groove through the air suction hood. The air suction hood has a funnel-shaped air intake. The air suction hood is disposed on the outer peripheral surface of the distribution block and is connected to the arc-shaped air groove. The outer peripheral surface of the distribution block has a connecting hole that communicates with the arc-shaped air groove. The connecting hole extends along the circumference of the distribution block and its length is adapted to the size of the air intake. This structure can improve the negative pressure intensity of the arc-shaped air groove.

[0012] The suction port is a hemispherical shape adapted to the popping beads. This structure can ensure the adsorption strength of the popping beads and prevent them from falling off during the adsorption process.

[0013] It also includes a conveying mechanism for conveying sanitary products, which is positioned below the adding roller so that the sanitary products can receive the popping beads falling from the suction port.

[0014] The distribution block is also provided with an air blowing hole connected to a positive pressure source. The air blowing hole can be arranged opposite to the input port. When the popping beads cannot fall freely from the suction port, the air blowing hole can help the popping beads get out of the suction port. Attached Figure Description

[0020] Reference Figures 1 to 4 As shown, a bursting bead adding device is used to add bursting beads to hygiene products. It includes an adding roller 1, a hopper 2, a negative pressure assembly 3, and a conveying mechanism 4. The adding roller 1 is rotatably mounted on the frame of a hygiene product production line via a rotating shaft 14. Multiple suction ports 13 are arranged circumferentially on the outer circumferential surface of the adding roller 1. Multiple negative pressure channels 11 are arranged circumferentially and connected to the corresponding suction ports 13 within the adding roller 1. Specifically, each negative pressure channel 11 extends axially along the adding roller 1, with its input port located on the end face of the adding roller 1. The negative pressure channels 11 are connected to the suction ports 13 via branch channels 12 extending radially along the adding roller 1. The input ports of the multiple negative pressure channels 11 are arranged circumferentially around the axis of the adding roller 1. The negative pressure assembly 3 includes a distribution block 31, a negative pressure source, and a suction hood 32. The distribution block 31 is circular and has radially extending sections to avoid the adding roller. The rotating shaft 14 has a clearance notch 33, and the distribution block 31 is fixedly installed. The end face of the distribution block 31 is arranged close to the end face of the adding roller 1. The end face of the distribution block 31 forms an arc-shaped air groove 311 that is arranged opposite to the input port of the negative pressure channel 11. The negative pressure source is connected to the arc-shaped air groove 311 through the suction hood 32. The suction hood 32 has a trumpet-shaped suction port. The suction port is fixedly covered on the outer peripheral surface of the distribution block 31 and is connected to the arc-shaped air groove 311. The outer peripheral surface of the distribution block 31 forms a connecting hole 312 that is connected to the arc-shaped air groove 311. The connecting hole 312 extends along the circumference of the distribution block 31, and the length of the connecting hole is adapted to the suction port. This structure can improve the negative pressure strength of the arc-shaped air groove 311. The suction port 13 is a hemispherical shape adapted to the popping beads. This structure can ensure the adsorption strength of the popping beads and prevent the popping beads from falling off during the adsorption process. The negative pressure source is connected to the arc-shaped air groove 311 to provide negative pressure to the arc-shaped air groove 311. The hopper 2 is used to store and provide popping beads to the suction port 13 on the outer periphery of the adding roller 1. When the adding roller 1 rotates, the negative pressure channel 11 opposite to the arc-shaped air groove 311 forms a negative pressure, causing the corresponding suction port 13 to adsorb the popping beads. The negative pressure of the negative pressure channel 11 that is offset from the arc-shaped air groove 311 disappears, causing the popping beads of the corresponding suction port 13 to fall onto the sanitary products.

[0021] The distribution block 31 is also provided with an air blowing hole 34 connected to the positive pressure source. The air blowing hole 34 can be arranged opposite to the input port. When the popping bead cannot fall freely from the suction port 13, the air blowing hole 34 can help the popping bead get out of the suction port 13.

[0022] The side of the hopper 2 is closed by the outer peripheral surface of the adding roller 1, so that the popping beads in the hopper 2 come into contact with the outer peripheral surface of the adding roller 1 and are adsorbed by the suction port 13. This structure ensures that the suction port 13 and the popping beads are in full contact, ensuring that each suction port 13 can effectively pick up the popping beads. The hopper 2 is at least partially made of transparent material to allow observation of the material level. The hopper 2 includes a hopper wall 22 that is in contact with the outer peripheral surface of the adding roller. The hopper wall 22 is made of elastic material, such as silicone or rubber. Since the hopper 2 is fixedly set, the use of elastic material for the hopper wall 22 can ensure a reliable closed connection between the rotating adding roller 1 and the hopper 2, preventing the popping beads from leaking.

[0023] The conveying mechanism 4 is located directly below the adding roller 1 for conveying sanitary products, so that the sanitary products can receive the popping beads falling from the suction port 13. The structure of the conveying mechanism 4 is known prior art and will not be described in detail here.

[0024] In the above scheme, when the adding roller 1 rotates, the negative pressure channel 11 opposite to the inlet and the arc-shaped air groove 311 forms a negative pressure, causing the corresponding suction port 13 to adsorb the popping beads. When the negative pressure of the negative pressure channel 11 that is offset from the inlet and the arc-shaped air groove 311 disappears, the popping beads of the corresponding suction port 13 fall onto the sanitary products. The above scheme has a simple structure and can efficiently add popping beads to sanitary products.

[0025] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model shall still fall within the scope of the patent of the present utility model.
