Description

Technical Field

[0001] The utility model belongs to the field of packaging machinery, in particular to a strip packaging machine. Background Art

[0002] The strip packaging machine is generally used for conveying, sealing, punching and outputting materials into back-sealed packaging bags. Its equipment includes a frame mechanism, a packaging film transmission mechanism, a film guide mechanism, a liquid material conveying mechanism, a horizontal sealing mechanism, and a punching device.

[0003] The above-mentioned packaging film transmission mechanism has the following problems: 1. When the packaging film is transported by a series of guide mold shafts of the unwinding mechanism, the material is prone to deviation, affecting production. 2. During the use and consumption of the packaging film, the material roll gradually becomes smaller and lighter, and the driving motor pulls the packaging film unstably. 3. When the material is changed, the traction pressure roller needs to be adjusted manually to create a gap between the traction pressure roller and the active rubber wheel so that the material can be taken out and the packaging film can be changed. However, manually adjusting the position of the traction pressure roller delays the production rhythm. 4. When the packaging film is changed, the packaging film needs to be cut. The packaging film has no unlimited position device, which makes the operator cut the packaging film unevenly, resulting in waste in subsequent use.

[0004] The above-mentioned liquid material conveying mechanism has the following problems: the liquid injection into the material bag cannot be carried out at the same time as the sealing and pulling of the material bag by the external transverse sealing mechanism, and needs to be completed at an independent time. Otherwise, during the pulling of the material bag, the liquid material will remain in the next material bag and the sealing part, affecting the sealing of the material bag. However, such independent operation will affect the beat of the entire equipment.

[0005] The above-mentioned longitudinal sealing mechanism has the following problems: the longitudinal sealing mechanism is mainly driven by an air cylinder, which consumes a large amount of gas and has a low operating frequency. The overall sealing effect is affected by the fluctuation of compressed air, and the sealing center of the strip bag is not pressed firmly, resulting in a lower qualified rate of finished bags.

[0006] The above-mentioned transverse sealing mechanism has the following problems: 1. When the bag mouth is sealed in a mesh shape, the sealing head needs a long heating time to complete the bag sealing, which affects the equipment cycle. 2. This form of sealing is prone to liquid and bubbles inside the adjacent sealing parts of two bags, affecting product quality. Summary of the invention

[0016] In the packaging film transmission mechanism of this device: 1. The deviation of the packaging film is prevented by using a deviation correction group. The side of the packaging film passes through the inside of the U-shaped sensor. When the packaging film deflects to the trigger sensor, the electric cylinder of the deviation correction group pushes the unwinding mechanism to move and align.

The side of the film roll shaft in the unwinding mechanism is connected to the magnetic powder brake through a gear, and the magnetic powder brake can adjust the torque as required. When the packaging film on the unwinding roller is consumed, the torque of the unwinding roller is consistent, so that the driving motor can pull the packaging film stably. 3.

The operator can use a tool to complete the straight-line cutting of the packaging film according to the limit of the cutting groove. Make the packaging film regular after the change of shape.

[0017] In the liquid material following conveying mechanism of this device: the injection needle is driven by a servo motor and moves up and down synchronously with the external transverse sealing mechanism. The injection can be carried out simultaneously with the sealing and pulling bag action of the external transverse sealing mechanism, and does not require independent time to complete. At the same time, it avoids the liquid material remaining in the next bag and the sealing part during the pulling bag process; improves the operation rhythm of the equipment.

[0018] In the longitudinal sealing mechanism of this device: 1. During maintenance or shutdown, the cylinder drive group can be activated to push the front sealing group forward, so that the front sealing group is away from the packaging film to prevent the packaging film from being heated and deformed for a long time. At the same time, the servo motor is used to drive the front sealing mechanism to achieve stable action, small amplitude, uniform sealing pressure, and good longitudinal sealing.

[0019] In the combined sealing transverse sealing mechanism of the device: there are two sets of upper and lower transverse sealing mechanisms, the vertical grain sealing head in the upper transverse sealing mechanism is pressed and heated to form the vertical grains in the material bag mesh, and the horizontal grain sealing head in the lower transverse sealing mechanism is pressed and heated to form the horizontal grains in the material bag mesh. The heating time of this sealing method is shorter than that of the method of forming the mesh once, thereby providing an improvement in the equipment beat. The mesh is heated and sealed separately by the vertical grains and the horizontal grains, and the material liquid at the sealing connection can be driven into the material bag cavity when the vertical grains are sealed, avoiding the situation of liquid inclusion and bubbles, and improving product quality.

[0069] When in use, the packaging film is installed on the film roll shaft 21011 in the unwinding mechanism 21, and is wound onto each roller in the required order, passing through the film connection plate 21017 on the way. The film connection plate 21017 is provided with air holes and cutting grooves. The film connection plate 21017 is externally connected to a negative pressure air source, and the packaging film is adsorbed by the air holes of the film connection plate 21017. During the winding process of the packaging film, it passes through the width adjustment sensor 2302. When the packaging film deflects to trigger the width adjustment sensor 2302, the electric cylinder of the deviation correction group pushes the unwinding mechanism to move and align. The packaging film enters between the traction pressure roller 2202 and the active rubber roller 2201 by turning to the third film guide shaft 2203. The traction pressure roller 2202 can move with the first cylinder 2206 to complete the compression or gap with the active rubber roller 2201. When the two rollers are pressed tightly, the active rubber roller 2201 is driven by the servo motor 2204 to complete the output of the packaging film.

[0070] The packaging film passes through a plurality of mold guide shafts 32 in the film guiding mechanism 3 and is transmitted to the slitting group 4 .

[0071] The servo motor 41 runs, driving the driving shaft 44 and the lower cutter 45 on it to rotate, and the passive shaft 44 engages with the driving shaft 43 and moves with it. The spring between the fixed block 48 and the upper cutter 46 makes the upper and lower cutters fit together. After the packaging film contacts the rotating cutter, it becomes equally divided strips.

[0072] The liquid material follows the conveying mechanism 5 to receive the liquid raw material, and the injection needle 52 passes through the funnel 6101 and is inserted into the material bag. After the combined sealed transverse sealing mechanism 7 seals the bag mouth, the material bag is pulled downward. During the pulling process of the material bag, the injection needle 52 begins to inject liquid into the material bag, and at the same time, the servo motor 5301 is activated to drive the first ball screw 5302 to rotate. The first ball screw nut 5303 drives the fourth support frame 5306 and the injection needle 52 to move downward with the material bag, ensuring that the relative position of the injection needle 52 and the combined sealed transverse sealing mechanism 7 remains unchanged. After the combined sealed transverse sealing mechanism 7 is pulled and the injection needle 52 is injected, the liquid stops being transported, and the servo motor 5301 drives the injection needle 52 to follow the combined sealed transverse sealing mechanism 7 back to the initial position to prepare for the injection of the next material bag.

[0073] The packaging film enters the longitudinal sealing mechanism 6, moves downward along the gap between the funnel 6101 and the limiting clamp block 6103, forms a barrel shape, and extends and limits the edge of the packaging film at the gap of the limiting block 6103. The second servo motor 6501 is activated, and through the detection of the limiting block 6508 and the sensor 6509, a small reciprocating rotation of the shaft 6506 is completed, thereby pushing the second connecting rod 6507 forward and retracting. The eccentric shaft 6304 is driven to rotate through the fisheye joint 6302 and the sealing rocker 6303, and the connecting block 6305 is pushed to rotate. The front sealing group 62 is driven to move along a specific curve to complete the opening and closing of the front sealing group 62 and the rear sealing group 61. The sealing of the packaging film is achieved by pressurized heating. At the same time, during maintenance or shutdown, the cylinder drive group 64 can be activated to push the front sealing group 62 forward, so that the front sealing group 62 is away from the packaging film to prevent the packaging film from being heated and deformed for a long time.

[0074] In the combined sealed transverse sealing mechanism 7, the material bag passes through the two transverse sealing mechanism groups 71 from the top of the mechanism. The first servo motor 71046 is running, and the transmission shaft 71041 drives the connecting rod 710412 and the driving connecting rod 710417 to move, pushing the transverse sealing rear sealing group 7101 and the transverse sealing front sealing group 7102 to clamp the material bag to open and close. When the first transverse sealing mechanism group 71 at the upper end is closed, the heating rod inside the mechanism conducts heat to the sealing head 71017 and the sealing block 71024, heating the edge of the material bag, so that the material bag is sealed and vertical lines are formed at the mouth of the material bag. This process can drive the liquid material in the material bag to the two ends of the sealing to avoid the appearance of liquid bubbles after complete sealing. After the mechanism completes clamping the bag, the fourth servo motor 7205 of the stepping transmission group 72 drives the second ball screw 7201 to rotate, and the ball screw nut 7202 drives the transverse sealing mechanism group 71 and the bag to move downward along the linear guide rail 7402 by a distance X, where X is less than the length of the bag. Then the transverse sealing mechanism group 71 clamps and releases, and the fourth servo motor 7205 drives the transverse sealing mechanism group 71 to move upward along the linear guide rail 7402. The first transverse sealing mechanism group 71 on the upper layer clamps and releases, while the second transverse sealing mechanism group 71 closes and clamps the bag to heat it, and performs the second sealing of the other end of the bag. The surface of the sealing head of the second transverse sealing mechanism group 71 is in the form of horizontal lines, forming horizontal lines at the mouth of the bag. In this way, it is combined with the vertical lines formed by the first transverse sealing mechanism group 71 to form a mesh pattern. Then the second stepping transmission group 72 drives the second transverse sealing mechanism group 71 to move down along the linear guide rail 7402 for a distance Y, and then releases after the bag width length. The sum of X and Y is the length of one bag. That is, the upper and lower transverse sealing mechanism groups 71 are close to or away from each other. The clamping and release states of the two transverse sealing mechanism groups 71 cannot be the same, that is, one transverse sealing mechanism group 71 is clamped, and the other transverse sealing mechanism group 71 is released. The balance tension spring group 73 is combined with the support plate 7401 and the upper and lower two transverse sealing mechanism groups 71 to reduce the load of the fourth servo motor 7205 pushing the transverse sealing mechanism group 71.

[0075] After passing through the transverse sealing mechanism, the material bag enters the pre-tear forming mechanism 82 and the punching mechanism 83 of the punching device 8, and is punched and cut at the pre-tear and the two material bags are separated by punching, and finally the finished product is output.
