Description

Technical Field

[0001] This utility model relates to the field of thin film material molding, specifically an automatic lifting device for accordion-style edge-inserted film bubbles. Background Technology

[0002] Existing tubular packaging films require edge insertion, which is performed as follows: First, the tubular packaging film is threaded into an edge insertion machine. The edge insertion machine has a vertical structure with pressure rollers fixed at the top and bottom. Near the bottom pressure roller, there is an adjustable edge insertion mechanism. The tubular packaging film enters from the top pressure roller and exits from the bottom pressure roller, connecting to the winding mechanism. Before edge insertion begins, the winding mechanism is stationary. Then, an air gun is used to poke a hole in the tubular packaging film between the top and bottom pressure rollers, inflating the film between them. The winding mechanism is then activated, moving the tubular packaging film towards it. Due to the constraint of the top and bottom pressure rollers, the air bubbles inside the tubular packaging film remain between them. As the tubular packaging film passes through the edge insertion mechanism, both sides are pushed inward by the mechanism.

[0003] However, as the insertion continues, the air inside the tubular packaging film will gradually be lost, causing the air pressure inside the tubular packaging film to drop, thus affecting the insertion effect; therefore, an automatic lifting device for the accordion-style insertion film bubble is proposed to address the above problem. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an automatic lifting device for the accordion insert edge bubble.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The accordion-style edge-inserting membrane bubble automatic lifting device of this utility model includes a frame, an edge-inserting mechanism installed at the bottom of the frame, an upper roller frame installed at the top of the frame, and a lower roller frame installed at the bottom of the frame. A pair of upper pressure rollers are rotatably connected inside the upper roller frame, and a pair of lower pressure rollers are rotatably connected to the lower roller frame. A lifting assembly is installed at the top of the frame, and the upper roller frame is mounted on the lifting assembly. The lifting assembly can drive the upper roller frame to move up and down. A distance sensor is also installed on the upper roller frame, and the distance sensor can obtain the distance between itself and the tubular membrane.

[0006] Preferably, the frame is also equipped with a limit switch that is triggered when the upper roller frame moves down to its lowest position.

[0007] Preferably, the distance sensor is an ultrasonic distance sensor.

[0008] Preferably, the lifting assembly includes a lead screw, a vertical frame, a drive shaft, and a lifting frame. The lead screw is rotatably connected to the top of the frame, and the vertical frame is installed on the top of the frame. The top end of the lead screw is rotatably connected to the vertical frame. The assembly also includes a drive mechanism capable of driving the lead screw to rotate.

[0009] Preferably, a guide rod is fixedly connected to the top of the frame, the guide rod is fixedly connected to the upright frame, and the lifting frame is slidably connected to the guide rod.

[0010] Preferably, the lifting frame is slidably connected to the guide rod via a linear bearing.

[0011] Preferably, the drive mechanism includes a motor and a drive shaft. The motor is fixedly mounted on the upright frame, and the drive shaft is rotatably connected to the machine frame through a bearing seat. The lead screw and the lifting frame are connected by a ball screw and nut pair. The upper roller frame is mounted on the lifting frame. The drive shaft and the lead screw are connected by transmission, and the motor and the drive shaft are connected by transmission.

[0012] Preferably, the drive shaft and the lead screw are connected by a gear transmission.

[0013] Preferably, the motor and the drive shaft are connected by a gear transmission.

[0014] Preferably, the gear is a bevel gear.

[0015] The advantages of this utility model are:

[0016] 1. This utility model, by setting up a lifting assembly and a distance sensor, allows the upper pressure roller to be mounted on the lifting assembly via an upper roller frame during use. The lifting assembly can move up and down and is equipped with a distance sensor, preferably an ultrasonic distance sensor, which is also fixedly mounted on the upper roller frame below the lifting assembly. When the distance sensor continuously detects the distance between itself and the packaging film, when the air pressure inside the packaging film drops, the air bladder between the upper and lower pressure rollers of the packaging film will contract and deflate. The distance sensor will detect that the distance to the packaging film has increased. At this time, the lifting assembly drives the upper pressure roller to move downward, making the height of the air bladder lower, thereby restoring the air pressure inside the packaging film. When the distance sensor detects that the distance to the packaging film has returned to normal, the tubular film is kept in an expanded state, which facilitates the preservation of the edge insertion effect.

[0017] 2. This utility model features a limit switch along the path of the lifting assembly as it descends. When the lifting assembly lowers the upper pressure roller to its lowest point, the limit switch is triggered, causing a stop alarm. At this point, the upper pressure roller needs to be reset and the tubular membrane needs to be refilled with air, making it convenient to use. Attached Figure Description

[0024] 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 scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 2-4 As shown, an automatic lifting device for accordion-style insert membrane bubbles includes a frame 16. An insert mechanism is installed at the bottom of the frame 16. An upper roller frame 11 is provided at the top of the frame 16, and a lower roller frame 13 is installed at the bottom of the frame 16. A pair of upper pressure rollers 12 are rotatably connected inside the upper roller frame 11, and a pair of lower pressure rollers 14 are rotatably connected to the lower roller frame 13. A lifting assembly is installed at the top of the frame 16, and the upper roller frame 11 is mounted on the lifting assembly, which drives the upper roller frame 11 to move up and down. A distance sensor 15 is also installed on the upper roller frame 11, which can acquire the distance between itself and the tubular membrane 1. A limit switch 2, triggered when the upper roller frame 11 moves to its lowest position, is also installed on the frame 16. The distance sensor 15 is an ultrasonic distance sensor.

[0027] In use, the upper pressure roller 12 is mounted on the lifting assembly via the upper roller frame 11. The lifting assembly can move up and down and is equipped with a distance sensor 15, preferably an ultrasonic distance sensor 15. The distance sensor 15 is also fixedly mounted on the upper roller frame 11 below the lifting assembly. When the distance sensor 15 continuously detects the distance between itself and the packaging film, when the air pressure inside the packaging film drops, the air bladder between the upper pressure roller 12 and the lower pressure roller 14 will contract and deflate. The distance sensor 15 will detect that the distance to the packaging film has increased. At this time, the lifting assembly drives the upper pressure roller 12 to move downward, making the height of the air bladder lower, thereby restoring the air pressure inside the packaging film, thus keeping the tubular film in an expanded state for easy edge insertion. When the distance sensor 15 detects that the distance to the packaging film has returned to normal, the lifting assembly stops descending. A limit switch 2 is set on the descent path of the lifting assembly. When the lifting assembly drives the upper pressure roller 12 to the lowest point, the limit switch 2 is triggered, thereby stopping the machine and alarming. At this time, the upper pressure roller 12 needs to be reset and the tubular film 1 needs to be re-inflated.

[0028] Furthermore, such as Figure 2-4 As shown, the lifting assembly includes a lead screw 32, a vertical frame 31, a drive shaft 33, a motor 34, and a lifting frame 35. The lead screw 32 is rotatably connected to the top of the frame 16. The vertical frame 31 is mounted on the top of the frame 16. The top end of the lead screw 32 is rotatably connected to the vertical frame 31. The motor 34 is fixedly mounted on the vertical frame 31. The drive shaft 33 is rotatably connected to the frame 16 through a bearing seat. The lead screw 32 and the lifting frame 35 are connected by a ball screw 32 and nut pair. The upper roller frame 11 is mounted on the lifting frame 35. The drive shaft 33 and the lead screw 32 are connected by gear transmission. The motor 34 and the drive shaft 33 are also connected by gear transmission. A guide rod 4 is fixedly connected to the top of the frame 16. The guide rod 4 is fixedly connected to the vertical frame 31. The lifting frame 35 is slidably connected to the guide rod 4 through a linear bearing.

[0029] In use, the motor 34 and the drive shaft 33, and the drive shaft 33 and the lead screw 32 are all driven by two bevel gears meshing with each other. The rotation of the lead screw 32 will drive the lifting frame 35 to move up and down. The upper roller frame 11 is installed on the lifting frame 35 to drive the upper pressure roller 12 to move up and down. The motor 34 is preferably a servo motor 34. Furthermore, a guide rod 4 is also fixedly connected to the frame 16. The lifting frame 35 is slidably connected to the guide rod 4 through a linear bearing, which can improve the stability of the lifting frame 35 and the upper pressure roller 12 moving up and down.

[0030] Working principle: During use, the upper pressure roller 12 is mounted on the lifting assembly via the upper roller frame 11. The lifting assembly can move up and down and is equipped with a distance sensor 15, preferably an ultrasonic distance sensor 15. The distance sensor 15 is also fixedly mounted on the upper roller frame 11 below the lifting assembly. When the distance sensor 15 continuously detects the distance between itself and the packaging film, when the air pressure inside the packaging film drops, the air bladder between the upper pressure roller 12 and the lower pressure roller 14 will contract and deflate. The distance sensor 15 will detect that the distance to the packaging film has increased. At this time, the lifting assembly drives the upper pressure roller 12 to move downward, making the height of the air bladder lower, thereby restoring the air pressure inside the packaging film. When the distance sensor 15 detects that the distance to the packaging film has returned to normal, the lifting assembly stops descending. A limit switch 2 is set on the descent path of the lifting assembly. When the lifting assembly drives the upper pressure roller 12 to the lowest point, the limit switch 2 is triggered, thereby stopping the machine and alarming. At this time, it is necessary to reset the upper pressure roller 12 and re-inflate the tubular film 1.

[0031] In use, the motor 34 and the drive shaft 33, and the drive shaft 33 and the lead screw 32 are all driven by two bevel gears meshing with each other. The rotation of the lead screw 32 will drive the lifting frame 35 to move up and down. The upper roller frame 11 is installed on the lifting frame 35 to drive the upper pressure roller 12 to move up and down. The motor 34 is preferably a servo motor 34. Furthermore, a guide rod 4 is also fixedly connected to the frame 16. The lifting frame 35 is slidably connected to the guide rod 4 through a linear bearing, which can improve the stability of the lifting frame 35 and the upper pressure roller 12 moving up and down.
