Description

Technical Field

[0001] This utility model relates to the field of blister packaging machine technology, and in particular to a feeding device for a blister packaging machine. Background Technology

[0002] Currently, blister packaging machines are crucial pieces of machinery in the pharmaceutical process, primarily used to package various sizes of capsules and other medicines to achieve mass production. Specifically, the blister packaging machine uses a punching device to cut the packaged PVC into multiple finished blister packs, which are then conveyed to a cartoning machine via a conveyor belt to complete the drug production. Simultaneously, during the punching process, the remaining portion of the PVC after removing the blister packs is considered waste. This waste needs further recycling to avoid adverse effects on the blister pack cutting process. Existing blister packaging machines typically handle waste by automatically cutting it. The waste is transported to a waste cutting device where a waste blade cuts it into smaller pieces, facilitating subsequent recycling through a waste bin and completing waste disposal.

[0003] However, during the process of conveying the aforementioned waste material to the waste cutting device, since the waste material is large PVC, it will sag under its own weight when it comes out of the punching device in sequence. This causes the waste material to be unable to be smoothly conveyed to the conveyor belt of the waste cutting device, affecting the subsequent waste cutting and thus affecting the normal operation of the entire equipment.

[0004] Therefore, this application proposes a feeding device for a blister packaging machine to solve the problems in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for a blister packaging machine, which can adjust the pressure plate appropriately according to the actual situation, and can also prevent blister waste from accumulating at the pressure plate. It also solves the problem that blister waste will sag under its own weight, causing the waste to be unable to be smoothly transported to the conveyor belt of the waste cutting device, thus affecting the subsequent waste cutting.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a blister packaging machine, including a squeezing mechanism for squeezing blister waste, a support, and a control panel;

[0007] Two drive rollers are rotatably connected to the bracket, and the two drive rollers are connected to the same conveyor belt for conveying blister waste. The bracket is equipped with a pressing mechanism for pressing the blister waste, and a control panel is installed on one side of the bracket. The pressing mechanism is connected to the control panel.

[0008] The extrusion mechanism includes a hydraulic cylinder, a frame, a rotating shaft, a pressure plate, pressure rollers, a first motor, a second motor, and a cam. The frame is slidably connected within the support, and the pressure plate is rotatably connected within the frame. Two pressure rollers are rotatably connected to the bottom of the pressure plate. A first motor is fixedly installed on one side of the pressure plate, and the output end of the first motor is fixedly connected to one end of one of the two pressure rollers. Through the coordinated design of the support, extrusion mechanism, transmission rollers, conveyor belt, third motor, and control panel, the pressure plate can be appropriately adjusted according to actual conditions, improving flexibility and preventing the accumulation of blister waste at the pressure plate. This improves the extrusion efficiency of blister waste and solves the problem of blister waste sagging under its own weight, preventing it from being smoothly conveyed to the conveyor belt of the waste cutting device and affecting subsequent waste cutting. This improves processing efficiency and convenience.

[0009] A further feature of this invention is that a hydraulic cylinder is fixedly installed on the top of the bracket, and one end of the hydraulic cylinder is fixedly connected to the frame. The frame can be moved up and down a certain distance by the drive of the hydraulic cylinder. At the same time, the frame drives the pressure plate to move synchronously through the cooperation of the rotating shaft and the cam, thereby achieving the effect of adjusting the distance between the pressure plate and the conveyor belt.

[0010] A further feature of this invention is that a rotating shaft is rotatably connected to the frame, and the rotating shaft is fixedly connected to the pressure plate, so that the pressure plate can reciprocate around the rotating shaft as the center.

[0011] A further feature of this invention is that: a mounting groove is provided on one side of the pressure plate, and a motor is fixedly installed in the mounting groove. The motor is connected to the control panel. A second mounting groove is provided on one side of the pressure plate, and the second mounting groove corresponds to one end of the two pressure rollers. The pressure plate and the two pressure rollers are both corresponding to the conveyor belt. Driven by the motor, the corresponding pressure rollers rotate on the pressure plate in the opposite direction to the rotation of the conveyor belt. Simultaneously, through the cooperation between the two drive wheels and the drive belt, the two pressure rollers rotate synchronously on the pressure plate and act on the blister waste, thereby avoiding the accumulation of blister waste at the pressure plate and improving the squeezing efficiency of the pressure plate on the blister waste.

[0012] A further feature of this invention is that: one end of each of the two pressure rollers is fixedly connected to a transmission wheel, and the two transmission wheels are connected to the same transmission belt. The transmission belt and the two transmission wheels are both adapted to the mounting groove for transmission, so that the two pressure rollers rotate synchronously.

[0013] A further feature of this invention is that a second electric motor is fixedly installed within the frame, and a cam is fixedly installed at the output end of the second electric motor. One end of the cam is in contact with the pressure plate. Both the second electric motor and the hydraulic cylinder are connected to the control panel. Driven by the second electric motor, the cam rotates and acts on the pressure plate. Under the action of the torsion spring, the pressure plate reciprocates around the rotating shaft. During this process, the interaction between the pressure plate and the conveyor belt achieves the purpose of squeezing the blister waste, thus compacting the blister waste.

[0014] A further feature of this invention is that a torsion spring is fixedly sleeved on one end of the rotating shaft, and one end of the torsion spring is fixedly connected to the frame. The pressure plate can be restored to its original shape by the elastic potential energy of the torsion spring. A third motor is fixedly installed on the bracket. The output end of the third motor is fixedly connected to one end of one of the two transmission rollers. The third motor is connected to the control panel, and the third motor is driven and controlled by a preset program in the control panel.

[0015] The beneficial effects of this utility model are as follows: Through the coordinated design of the bracket, extrusion mechanism, transmission roller, conveyor belt, motor, and control panel, the pressure plate can be appropriately adjusted according to the actual situation, which improves flexibility and avoids the accumulation of blister waste at the pressure plate, thereby improving the extrusion efficiency of blister waste. It also solves the problem that blister waste will sag under its own weight, causing the waste to be unable to be smoothly transported to the conveyor belt of the waste cutting device, thus affecting the subsequent waste cutting, thereby improving processing efficiency and convenience.

[0026] Two drive rollers 2 are rotatably connected to the support 1. The two drive rollers 2 are connected to the same conveyor belt 3 for conveying blister waste.

The first motor 9 is fixedly installed on one side of the pressure plate 7, and the output end of the first motor 9 is fixedly connected to one end of one of the two pressure rollers 8. Through the coordinated design between the support 1, the extrusion mechanism, the transmission roller 2, the conveyor belt 3, the third motor 14, and the control panel 15, the pressure plate 7 can be appropriately adjusted according to the actual situation, which improves flexibility and avoids the accumulation of blister waste at the pressure plate 7, thus improving the extrusion efficiency of blister waste. It also solves the problem that blister waste will sag under its own weight, causing the waste to be unable to be smoothly transported to the conveyor belt of the waste cutting device, affecting the subsequent waste cutting, thereby improving processing efficiency and convenience.

[0028] In this embodiment, a hydraulic cylinder 4 is fixedly installed on the top of the bracket 1. One end of the hydraulic cylinder 4 is fixedly connected to the frame 5. The frame 5 can be moved up and down a certain distance by the drive of the hydraulic cylinder 4. At the same time, the frame 5 drives the pressure plate 7 to move synchronously through the cooperation of the rotating shaft 6 and the cam 13, thereby achieving the effect of adjusting the distance between the pressure plate 7 and the conveyor belt 3.

[0029] In this embodiment, a rotating shaft 6 is rotatably connected to the frame 5, and the rotating shaft 6 is fixedly connected to the pressure plate 7, so that the pressure plate 7 can swing back and forth with the rotating shaft 6 as the center. An auxiliary pressure roller is rotatably installed at the bottom of the pressure plate 7 and corresponds to the two pressure rollers 8.

[0030] In this embodiment, a mounting groove 1 is provided on one side of the pressure plate 7, and a motor 9 is fixedly installed in the mounting groove 1. The motor 9 is connected to the control panel 15. A mounting groove 2 is provided on one side of the pressure plate 7, and the mounting groove 2 corresponds to one end of the two pressure rollers 8. The pressure plate 7 and the two pressure rollers 8 are both corresponding to the conveyor belt 3. The corresponding pressure rollers 8 are driven by the motor 9 to rotate on the pressure plate 7, and the pressure rollers 8 rotate in the opposite direction to the conveyor belt 3. At the same time, through the cooperation between the two transmission wheels 10 and the transmission belt 11, the two pressure rollers 8 rotate synchronously on the pressure plate 7 and act on the blister waste, thereby avoiding the accumulation of blister waste at the pressure plate 7 and improving the squeezing efficiency of the pressure plate 7 on the blister waste.

[0031] In this embodiment, a transmission wheel 10 is fixedly connected to one end of each of the two pressure rollers 8. The same transmission belt 11 is connected to the two transmission wheels 10. The transmission belt 11 and the two transmission wheels 10 are both adapted to the mounting groove for transmission, so that the two pressure rollers 8 rotate synchronously.

[0032] In this embodiment, a second motor 12 is fixedly installed inside the frame 5. A cam 13 is fixedly installed at the output end of the second motor 12. One end of the cam 13 is in contact with the pressure plate 7. The second motor 12 and the hydraulic cylinder 4 are both connected to the control panel 15. Driven by the second motor 12, the cam 13 rotates and acts on the pressure plate 7. Under the action of the torsion spring 16, the pressure plate 7 moves back and forth around the rotating shaft 6. During this process, through the interaction between the pressure plate 7 and the conveyor belt 3, the purpose of squeezing the blister waste can be achieved, so that the blister waste is compacted.

[0033] In this embodiment, a torsion spring 16 is fixedly sleeved on one end of the rotating shaft 6. One end of the torsion spring 16 is fixedly connected to the frame 5. The pressure plate 7 can be restored to its original shape by the elastic potential energy of the torsion spring 16. A motor 3 14 is fixedly installed on the bracket 1. The output end of the motor 3 14 is fixedly connected to one end of one of the two transmission rollers 2. The motor 3 14 is connected to the control panel 15. The motor 3 14 is driven and controlled by the preset program in the control panel 15.

[0034] Working principle: When in use, first connect the power supply and drive the electric hydraulic cylinder 4, electric motor 9, electric motor 12 and electric motor 14 through the preset program in the control panel 15.

[0035] First, the corresponding transmission roller 2 rotates on the support 1 and drives the conveyor belt 3, which in turn transports the blister waste to the pressure plate 7. Simultaneously, the cam 13 rotates and acts on the pressure plate 7, driven by the motor 12. With the assistance of the torsion spring 16, the pressure plate 7 reciprocates around the rotating shaft 6. During this process, the interaction between the pressure plate 7 and the conveyor belt 3 compresses the blister waste, making it compacted. This facilitates the transport of the blister waste to the waste cutting device and its processing, thus improving processing efficiency.

[0036] Meanwhile, the corresponding pressure roller 8 is driven by the motor 9 to rotate on the pressure plate 7, and the pressure roller 8 rotates in the opposite direction to the conveyor belt 3. At the same time, through the cooperation between the two drive wheels 10 and the drive belt 11, the two pressure rollers 8 rotate synchronously on the pressure plate 7 and act on the blister waste, thereby avoiding the accumulation of blister waste at the pressure plate 7 and improving the squeezing efficiency of the pressure plate 7 on the blister waste.

[0037] Driven by the hydraulic cylinder 4, the frame 5 can move up and down a certain distance. At the same time, the frame 5 drives the pressure plate 7 to move synchronously through the cooperation of the rotating shaft 6 and the cam 13, thereby achieving the effect of adjusting the distance between the pressure plate 7 and the conveyor belt 3. This facilitates the adjustment of the thickness of the blister waste compression according to the user's needs. Moreover, it facilitates the compression of blister waste of different thicknesses on the conveyor belt 3, improving convenience and flexibility.

[0038] The technological advancements of this invention compared to existing technologies are as follows: the pressure plate 7 can be appropriately adjusted according to actual conditions through the cooperation of various components, improving flexibility and preventing the accumulation of blister waste at the pressure plate 7, thus improving the extrusion efficiency of blister waste. It also solves the problem that blister waste will sag under its own weight, causing the waste to be unable to be smoothly transported to the conveyor belt of the waste cutting device, affecting subsequent waste cutting. This improves processing efficiency and convenience, making it more practical.
