Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a vertical traction automatic packaging machine. Background Technology

[0002] In the fields of biomedicine and laboratory testing, glass slides serve as an important sample carrier medium, and their packaging process has strict requirements for cleanliness, sealing, and labeling accuracy. Traditional packaging machines generally suffer from the following technical defects:

[0003] Traditional packaging machines are typically horizontal traction packaging machines, which have problems such as large footprint and high risk of glass slide flipping. Especially when handling ultra-thin glass slides with a thickness of ≤1mm, horizontal conveying is prone to stacking misalignment due to vibration. Existing vertical traction packaging machines lack an effective visual correction system. Most existing equipment uses mechanical limit switches or infrared photoelectric sensors for position detection, which have low sensitivity to the recognition of printed marks on the packaging film surface (especially for low-contrast markings). When encountering dark packaging substrates or reflective materials, false triggering or missed detection often occurs, resulting in a packaging bag sealing and cutting position deviation of more than ±2mm (the industry standard requires ≤±0.5mm). To address these issues, we provide a vertical traction automatic packaging machine to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an automatic packaging machine with vertical traction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic packaging machine with vertical traction includes a frame, on which guide rollers and guide rods for guiding and conveying packaging film are rotatably mounted. Black marks are printed at equal intervals on the surface of the packaging film. Two drive rollers for vertical traction and conveying of the packaging film are rotatably mounted on the frame. A first fixed frame and a second fixed frame are fixedly mounted on the frame from top to bottom, and the drive rollers are located between the first fixed frame and the second fixed frame. A heat-sealing mechanism for heat-sealing the packaging film is provided on the first fixed frame, and a cutting mechanism for cutting the heat-sealed packaging film is provided on the second fixed frame.

[0007] A motor is fixed on the frame, one of the drive rollers is installed at the output end of the motor and is driven to rotate by the motor, and the two drive rollers are transmitted through a gear mechanism.

[0008] An industrial camera for identifying black marks is fixed to the bottom of the second mounting bracket. The industrial camera is connected to the motor electrical signal via a wire.

[0009] As described above, a vertical traction automatic packaging machine has guide rollers and guide rods symmetrically distributed on the frame, which are used to guide and convey two sets of packaging films.

[0010] As described above, an automatic packaging machine with vertical traction: the heat sealing mechanism includes two first cylinders fixed on a first fixed frame, the output end of the first cylinder is provided with a first piston rod, and a heat sealing plate is fixed on the first piston rod.

[0011] An automatic packaging machine with vertical traction as described above: the gear mechanism includes gears fixed on two drive rollers respectively, and the two gears mesh with each other.

[0012] An automatic packaging machine with vertical traction as described above: the cutting mechanism includes two second cylinders fixed on a second fixed frame, a second piston rod is provided at the output end of the second cylinder, a spring is fixed on the second piston rod, and a cutting blade is fixed at the end of the spring.

[0013] A vertically traction automatic packaging machine as described above: a material collection box is fixed on the frame and located below the second fixed frame.

[0014] The above describes a vertically traction automatic packaging machine: the industrial camera used is a high frame rate industrial camera of 200fps or higher.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, two sets of packaging films are respectively wrapped around the guide roller, guide rod, and drive roller. Starting the motor can drive the drive roller to rotate intermittently, thereby enabling the packaging film between the two drive rollers to be intermittently vertically conveyed through extrusion. When the packaging film is conveyed to the guide roller, a glass slide is placed between the two packaging films. When the packaging film continues to be conveyed downward to the side of the first fixed frame, the two sets of packaging films are heat-sealed by the heat-sealing mechanism, and the glass slide is packaged by the two sets of packaging films. The packaged glass slide is then conveyed downward by the drive roller. When it is conveyed to the side of the second fixed frame, the packaging film after packaging the glass slide is cut by the cutting mechanism. Thus, this utility model solves the problems of large footprint and high risk of glass slide overturning in traditional horizontal traction glass slide packaging machines by setting a vertical traction structure to package the glass slide.

[0016] In addition, this utility model installs an industrial camera at the bottom of the second fixed frame. The industrial camera uses a high frame rate of over 200fps. Black marks are printed at equal intervals on the surface of the packaging film. The industrial camera can capture images of the packaging film surface in real time and accurately identify the positioning marks of the black marks. When the industrial camera fails to identify the positioning marks of the black marks, it controls the motor to stop, the packaging film stops vertically conveying downwards, and the packaging operation is suspended. The industrial camera's identification of the black marks solves the problem that traditional methods of using mechanical limit switches or infrared photoelectric sensors for position detection have low sensitivity in identifying printed marks on the surface of the packaging film and cannot automatically identify printing defects in the packaging film. The industrial camera can better identify black contamination or printing defects in the marked area, helping the system to avoid incorrectly performing the packaging action and avoiding batch quality accidents.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5As an embodiment of this utility model, an automatic packaging machine with vertical traction includes a frame 1. A guide roller 2 and a guide rod 3 are rotatably arranged on the frame 1 for guiding and conveying the packaging film 4. Black marks 20 are printed at equal intervals on the surface of the packaging film 4. Two drive rollers 10 are rotatably arranged on the frame 1 for vertically traction and conveying the packaging film 4. A first fixed frame 5 and a second fixed frame 13 are fixed on the frame 1 from top to bottom, and the drive rollers 10 are located between the first fixed frame 5 and the second fixed frame 13. A heat sealing mechanism for heat sealing the packaging film 4 is provided on the first fixed frame 5, and a cutting mechanism for cutting the heat-sealed packaging film 4 is provided on the second fixed frame 13.

[0025] A motor 12 is fixed on the frame 1. A drive roller 10 is installed at the output end of the motor 12 and is driven to rotate by the motor 12. The two drive rollers 10 are transmitted through a gear mechanism.

[0026] An industrial camera 18 for identifying the black mark 20 is fixed at the bottom of the second mounting bracket 13. The industrial camera 18 is electrically connected to the motor 12 via wires.

[0027] In this embodiment, during use, two sets of packaging films 4 are respectively wound around the guide roller 2, guide rod 3, and drive roller 10. The motor 12 is electrically connected to an external power source via wires. Starting the motor 12 can drive one drive roller 10 to rotate intermittently. The gear mechanism between the two drive rollers 10 drives the other drive roller 10 to rotate synchronously and intermittently. This synchronous and intermittent rotation of the two drive rollers 10 allows the packaging film 4 between the two drive rollers 10 to be intermittently conveyed vertically downwards by compression. When the packaging film 4 is conveyed to the guide roller 2, the two packaging films... Glass slides are placed between the two sets of packaging films 4. When the packaging film 4 continues to be conveyed downward to one side of the first fixed frame 5, the two sets of packaging films 4 are heat-sealed by the heat-sealing mechanism. The glass slides are then heat-sealed by the two sets of packaging films 4. The packaged glass slides are then conveyed downward by the drive roller 10. When they are conveyed to one side of the second fixed frame 13, the packaging film 4 is cut by the cutting mechanism. Thus, this utility model solves the problems of large footprint and high risk of glass slide overturning in traditional horizontal traction glass slide packaging machines by setting a vertical traction structure to package the glass slides.

[0028] As a further embodiment of this utility model, guide rollers 2 and guide rods 3 are symmetrically distributed on the frame 1, and guide rollers 2 and guide rods 3 are used to guide and transport the two sets of packaging films 4.

[0029] In this embodiment, the glass slide is packaged by synchronously conveying two sets of packaging films 4 and by using the two sets of packaging films 4 to fit together.

[0030] As a further embodiment of this utility model, the heat sealing mechanism includes two first cylinders 6 fixed on the first fixed frame 5, the output end of the first cylinder 6 is provided with a first piston rod 7, and a heat sealing plate 8 is fixed on the first piston rod 7.

[0031] In this embodiment, the first cylinder 6 is electrically connected to an external power source via a wire. Activating the first cylinder 6 can drive the first piston rod 7 to extend and retract, thereby moving the heat sealing plate 8 horizontally. By having the two heat sealing plates 8 move horizontally synchronously, the packaging film 4 passing through the gap between them can be heat-sealed.

[0032] As a further embodiment of this utility model, the gear mechanism includes gears 11 respectively fixed on two drive rollers 10, and the two gears 11 mesh with each other.

[0033] In this embodiment, one drive roller 10 rotates, which drives the gear 11 on the drive roller 10 to rotate. The meshing between the two gears 11 drives the gear 11 on the other drive roller 10 to rotate, thereby causing the two drive rollers 10 to rotate relative to each other.

[0034] As a further embodiment of this utility model, the cutting mechanism includes two second cylinders 14 fixed on the second fixed frame 13. The output end of the second cylinder 14 is provided with a second piston rod 15. A spring 16 is fixed on the second piston rod 15, and a cutting blade 17 is fixed at the end of the spring 16.

[0035] In this embodiment, the second cylinder 14 is electrically connected to an external power source via a wire. Activating the second cylinder 14 can drive the second piston rod 15 to extend and retract, thereby driving the cutting blade 17 at the end of the spring 16 to move horizontally. The horizontal opposing movement of the two cutting blades 17 can cut the heat-sealed packaging film 4 between them. The flexible cutting mode of the spring 16 reduces collision damage to the cutting blades 17.

[0036] As a further embodiment of this utility model, a collection box 19 is fixed on the frame 1 and located below the second fixed frame 13.

[0037] In this embodiment, the cut finished product automatically falls into the collection box 19 for collection.

[0038] As a further embodiment of this invention, the industrial camera 18 adopts a high frame rate industrial camera of 200fps or higher.

[0039] In this embodiment, the industrial camera 18 is a high frame rate industrial camera of 200fps or higher. A camera of 200fps or higher refers to a camera that can capture images of more than 200 frames per second. It can capture dynamic scenes at extremely high speeds and obtain clear images in both bright and dark environments. The industrial camera 18 can better identify black contamination or printing defects in the marked area, helping the system to avoid incorrectly performing packaging actions and preventing batch quality accidents.

[0040] The working principle of this utility model is as follows: In use, two sets of packaging films 4 are unwound and wound onto guide roller 2, guide rod 3, and drive roller 10 respectively. Starting motor 12 drives one drive roller 10 to rotate intermittently. The gear mechanism between the two drive rollers 10 drives the other drive roller 10 to rotate synchronously and intermittently. This synchronous rotation of the two drive rollers 10 allows the packaging film 4 between the two drive rollers 10 to be intermittently conveyed vertically downwards through compression. When the packaging film 4 reaches guide roller 2, a glass slide is placed between the two packaging films 4. As the packaging film 4 continues to be conveyed downwards to one side of the first fixed frame 5, starting first cylinder 6 drives first piston rod 7 to extend and retract, thereby moving heat-sealing plates 8 horizontally. The synchronous horizontal movement of the two heat-sealing plates 8 allows for heat sealing of the packaging film 4 passing through their gaps. The glass slide is then heat-sealed by the two sets of packaging films 4. The packaged glass slide is then conveyed by the drive roller 10. The moving roller 10 drives the downward conveying. When the conveyed material reaches the side of the second fixed frame 13, the second cylinder 14 is activated to drive the second piston rod 15 to extend and retract, thereby driving the cutting blade 17 at the end of the spring 16 to move horizontally. The two cutting blades 17 move horizontally in opposite directions to cut the heat-sealed packaging film 4 that has passed between them. The industrial camera 18 can capture the surface image of the packaging film in real time and accurately identify the positioning mark 20 of the black mark. When the industrial camera 18 identifies the positioning mark 20 of the black mark, it means that the conveying position of the packaging film 4 has not deviated and the packaging operation can be carried out. When the industrial camera 18 does not identify the positioning mark 20 of the black mark, the motor 12 is controlled to stop, the packaging film 4 is no longer conveyed vertically downward, and the packaging operation is suspended. Thus, this utility model solves the problems of large footprint and high risk of glass slide overturning in traditional horizontal traction glass slide packaging machines by setting a vertical traction structure for packaging glass slides.

[0041] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
