Description

Technical Field

[0001] This utility model belongs to the technical field of foot bath powder pack sealing, and in particular relates to a foot bath powder pack sealing mechanism. Background Technology

[0002] Foot bath powder packets are medicinal packets for foot soaking. The foot bath packets contain materials such as mugwort that have been processed into powder. Foot bath powder packets usually contain an appropriate amount of materials packaged in small bags. They are convenient to use and widely applicable. After the packaging bag is finished, it needs to be sealed with a sealing device to prevent the materials from falling out of the packaging bag.

[0003] Currently, when powder is filled into powder bags, the packaging bags absorb powder particles, leaving some powder residue in the area to be sealed, which is not conducive to subsequent sealing operations.

[0004] To address the aforementioned issues, this application proposes a sealing mechanism for foot bath powder packets. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing mechanism for foot bath powder packets, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sealing mechanism for foot bath powder packets, including a packaging bag and a sealing mechanism;

[0008] The sealing mechanism has three working areas: an upper, middle, and lower area, which are a leveling area, a sealing area, and a cutting area, respectively.

[0009] The sealing area is equipped with a sealing part and a sealing strip on its inner side, and the slitting area is equipped with a slitting part and a slitting knife and a knife holder on its inner side;

[0010] The sealing mechanism is equipped with multiple sets of pressure rollers on its inner side, which have two working states: up and down movement and back and forth movement. Each set of pressure rollers is distributed on both sides of the packaging bag to be sealed area. The sealing mechanism is equipped with a loop-shaped circulation part on its inner side, and the pressure rollers are located on both sides of the circulation part.

[0011] Preferably, the upper and lower pressure rollers form a set, and a fixing block is fixed on the side of the circulation section, located in the middle area of ​​the adjacent pressure rollers.

[0012] Preferably, the side of the fixed block is provided with a slider that can move back and forth, and electric telescopic devices are fixedly installed between the fixed block and the slider, as well as at the upper and lower ends of the slider.

[0013] Preferably, the movable ends of the electric telescopic actuators at both ends of the slider are fixedly connected to the support blocks extending towards the circulation section at both ends of the pressure roller.

[0014] Preferably, the distance between adjacent pressure rollers when they separate vertically is greater than the vertical width of the sealing strip, the slitting knife, and the knife holder.

[0015] Preferably, the sealing strip, slitting knife, and knife holder move in and out of the area separated by adjacent pressure rollers via an electric telescopic device.

[0016] Preferably, the circulation section is used to control the pressure roller to enter the sealing area and the opening area after cutting of the packaging bag.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes the symmetrical and opposite movement of the pressure rollers to press against the packaging bag after powder filling. By moving in opposite directions, the residual powder particles in the area to be sealed are pushed out, thereby ensuring the flatness of the area to be sealed. This facilitates the sealing operation, and the sealing of the bag by flattening it also prevents leakage due to seal failure.

[0019] This invention uses the looping motion of the circulating part to drive a set of pressure rollers through the leveling area, sealing area and cutting area in sequence. The sealing and cutting operations are carried out by using the gap after the adjacent pressure rollers are separated, thus forming a cycle and continuously leveling the opening of the packaging bag during the sealing operation.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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.

[0031] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-5 As shown, this utility model is a foot bath powder pack sealing mechanism, including a packaging bag 1 and a sealing mechanism 2. The packaging bag moves from top to bottom, and the sealing mechanism 2 can be installed in the sealing operation area after the filling process of the filling equipment.

[0033] The sealing mechanism 2 has three working areas: a leveling area, a sealing area, and a cutting area.

[0034] The sealing area is equipped with a sealing part 21 and a sealing strip 211 on its inner side, and the slitting area is equipped with a slitting part 22 and a slitting knife 221 and a knife holder 222 on its inner side (the sealing part, sealing strip 21, slitting part, slitting knife and knife holder are all mature commercial products on the market and are existing equipment, so they will not be described in detail here).

[0035] The sealing mechanism 2 has multiple sets of pressure rollers 231 on its inner side. Two pressure rollers 231 form a group, with two working states: vertical movement and forward / backward movement. Each group of pressure rollers 231 is distributed on the front and back sides of the area to be sealed on the packaging bag 1. During operation, the pressure rollers 231 first move forward / backward, with the pressure rollers 231 on the front and back sides of the packaging bag 1 pressing against the sides of the bag opening. Then, they move vertically, creating a pushing force on the powder particles inside the bag opening, causing the powder particles to move upward and downward, thus achieving a leveling process. The sealing mechanism 2 has a loop-shaped circulation part 23 installed on its inner side, which can be a drive belt, a drive chain, or other means capable of achieving this. In the existing equipment with the current circular motion, the pressure rollers 231 are located on both sides of the circulation section 23. The circulation section 23 is used to control the pressure rollers 231 to enter the sealing area and the opening area after cutting of the packaging bag 1. After the lowermost pressure roller 231 moves out, the outermost pressure roller 231 moves to the side of the packaging bag 1. During this period, the filling operation is carried out. After the filling operation, the circulation section 23 moves, thereby driving the pressure rollers 231 to enter the sealing area of ​​the packaging bag 1 for leveling operation. The spacing between adjacent groups of pressure rollers 231 is equal and can be adjusted to be equal to the vertical length of each segment of the bag body by bolt installation according to actual production needs.

[0036] Furthermore, a fixing block 232 is fixed to the side of the circulation section 23, located in the middle area of ​​the adjacent pressure rollers 231. The side of the fixing block 232 is provided with a sliding block 233 that moves back and forth, used to drive the pressure rollers 231 to move back and forth. An electric telescopic device 234 is fixedly installed between the fixing block 232 and the sliding block 233, with its movable end fixedly connected to the sliding block 233. Electric telescopic devices 234 are fixedly installed at both the upper and lower ends of the sliding block 233. An integral support block 2311 extends from both ends of the pressure rollers 231 toward one side of the circulation section 23. The movable ends of the electric telescopic devices 234 at both the upper and lower ends of the sliding block 233 are fixedly connected to the support block 2311. The electric telescopic devices 234 at this location are used to drive the two pressure rollers 231 of a set to move up and down for leveling operations.

[0037] Furthermore, the distance between adjacent pressure rollers 231 when they separate vertically, that is, the distance between the two pressure rollers 231 after the leveling operation, is greater than the vertical width of the sealing strip 211, the slitting knife 221, and the knife holder 222. The sealing strip 211, the slitting knife 221, and the knife holder 222 enter and exit the area after the adjacent pressure rollers 231 are separated through an electric telescopic device to perform sealing and slitting operations.

[0038] It is understood that this utility model can level the area to be sealed in a timely manner after the foot bath powder bag is filled, so that the residual powder particles on the inside of the packaging bag 1 in this area will affect the sealing and cutting operations. At the same time, the circulating structure allows the leveling mechanism to continuously adapt to the filling, sealing and cutting operations.

[0039] A specific application of the operation process in this embodiment is as follows: During use, the packaging bag 1 first passes through the leveling area where the uppermost pressure roller 231 is located. The electric telescopic device 234 on the side of the fixed block 232 presses the slider 233 against the packaging bag 1. Then, the electric telescopic devices 234 at both ends of the slider 233 send the support block 2311 out in both upward and downward directions, thereby pushing the powder particles at the opening of the packaging bag 1 to move in both upward and downward directions, thus creating a leveling effect. Subsequently, driven by the circulation section 23, the pressure roller 231 continues to squeeze the packaging bag 1 and enters the sealing area together. The sealing strip 2 on the inner side of the sealing section 21... Driven by the electric telescopic device, the bag body is sealed after being leveled by passing through the upper and lower adjacent pressure rollers 231. Then the sealing strip 211 moves out, and the pressure rollers 231 move down together with the packaging bag 1 into the cutting area. The cutting blade 221 and the blade holder 222 are driven by the electric telescopic device to pass through the upper and lower adjacent pressure rollers 231 to cut the bag body. After cutting, they move out. Further, the lowermost pressure roller 231 is driven by the return motion of the circulation part 23 to enter the side away from the packaging bag 1, while the uppermost pressure roller 231 on that side enters the side adjacent to the packaging bag 1, forming a cycle.
