Description

Technical Field

[0001] This invention relates to the field of bearing plastic bottle packaging technology, specifically to an automatic packaging machine and packaging method for bearing plastic bottles. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding. Due to societal needs, bearing plastic bottles are gradually becoming more widely used; however, packaging is required after manufacturing and during transportation.

[0003] Existing automatic packaging machines for bearing plastic bottles have certain shortcomings when packaging bearing plastic bottles. Usually, during the sealing process, the position of the heat seal cannot be easily changed according to the size of the plastic bottle. Furthermore, shorter plastic bottles require manual adjustment during packaging, which leads to equipment defects. To address these issues, we propose an automatic packaging machine and packaging method for bearing plastic bottles. Summary of the Invention

[0007] As a further embodiment of the present invention, a conveyor roller is rotatably mounted on the conveyor, and a receiving trough and a heat sealing channel are provided on opposite sides of the two side sealing boxes, with the receiving trough communicating with the heat sealing channel. An installation groove is provided on the upper wall of the heat sealing channel, and a rotating shaft is rotatably mounted inside the installation groove. A heat sealing disc is rotatably mounted on the rotating shaft, and the heat sealing disc can extend into the heat sealing channel and cooperate with it. An L-shaped mounting plate is provided through one side of the main threaded column, and a power disc is fixedly mounted on one end of the main threaded column that passes through the L-shaped mounting plate.

[0008] As a further embodiment of the present invention, an extension plate is fixedly installed on the side of the L-shaped mounting plate near the packaging body, an auxiliary threaded post is rotatably installed on the extension plate, a guide plate is spirally installed on the auxiliary threaded post, the end of the auxiliary threaded post near the power plate passes through the extension plate, and a belt connection group is fixedly installed between the auxiliary threaded post and the main threaded post.

[0009] As a further embodiment of the present invention, a sensor and a packaging plastic bottle are fixedly installed on the feeding platform, and the packaging plastic bottle is located behind the sensor. A feeding telescopic column is fixedly installed on the side of the sensor close to the packaging plastic bottle, and the feeding telescopic column cooperates with the packaging plastic bottle.

[0010] As a further embodiment of the present invention, the heat sealing assembly includes two heat sealing shafts rotatably mounted on the packaging body, with a packaging column passing between the two heat sealing shafts. Connecting gears are fixedly mounted on the two heat sealing shafts and mesh with each other. Multiple fan blades are fixedly mounted on the two heat sealing shafts, with two fan blades forming a group. Heat sealing strips are fixedly mounted on each of the multiple fan blades.

[0011] As a further embodiment of the present invention, heat sealing protrusions are fixedly installed on each of the multiple heat sealing strips, and slitting blades are fixedly installed on each of the multiple heat sealing strips. A lower packaging feed port is provided on the packaging body, and a packaging paper roller is rotatably installed on the packaging body. Both the packaging paper roller and the lower packaging feed port are for providing packaging materials to the heat sealing components.

[0012] As a further embodiment of the present invention, each of the multiple packaging columns is provided with a movable groove, and each of the multiple movable grooves is slidably installed with an infeed or retractable plate. A trapezoidal unloading plate is fixedly installed on the side of the packaging body near the conveyor, and the trapezoidal unloading plate cooperates with the infeed or retractable plate.

[0013] A packaging method for an automatic packaging machine for bearing plastic bottles, the specific steps of which are as follows:

[0014] Step 1: First, the qualified plastic bottles are transported to the loading platform through the feeding table, with the bottle opening facing inward. The sensor detects that the packaging column and the plastic bottle are aligned. At this time, the control platform sends the alignment information and starts the feeding telescopic column to push the plastic bottle onto the packaging column. The plastic bottle then pushes the feed tray to move, and the packaging column then moves the plastic bottle.

[0015] Step 2: After passing through the heat sealing shaft, the rotation of the heat sealing shaft drives the fan blades and heat sealing strips to rotate. At this time, the packaging paper roller and the lower packaging feed port provide packaging material to the heat sealing shaft. The packaging material is heat sealed by the heat sealing strip. At the same time, the packaging material is cut by the cutting blade. The packaging material is cut and heat sealed before the plastic bottle passes through the heat sealing shaft. The plastic bottle enters between the two packaging materials.

[0016] Step 3: After passing through the heat sealing shaft, the packaging material is cut and heat-sealed again to seal the front and back of the packaging material. Then, the packaging column continues to move the plastic bottle. When it reaches the set position, the infeed plate will cooperate with the trapezoidal unloading plate to push the plastic bottle out of the packaging column and onto the conveyor. The conveyor will then transport the plastic bottle. At this time, the guide plate will guide the transported plastic bottle. The packaging material on both sides will enter the heat sealing channel through the receiving chute, and the rotating shaft will drive the heat sealing plate to rotate. When the packaging material passes through the heat sealing channel, the heat sealing plate will heat-seal the packaging material on both sides of the plastic bottle to complete the packaging. When the length of the plastic bottle is different, the power plate can be rotated to drive the main thread column to rotate, thereby moving the position of the side sealing box. At the same time, the belt connecting group drives the auxiliary thread column on the extension plate to rotate, causing the guide plate on the auxiliary thread column to move. This makes it easier to adjust the position of the guide plate and the side sealing box according to the length of the plastic bottle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The conveyor system transports the packaged plastic bottles, and the guide plate directs the flow. The packaging materials on both sides then enter the heat sealing channel through the receiving chute. The rotating shaft drives the heat sealing disc to rotate. As the packaging materials pass through the heat sealing channel, the heat sealing disc heat seals the packaging materials on both sides of the plastic bottle, thus completing the packaging. When the lengths of the plastic bottles are different, the power disc can be rotated, which drives the main threaded column to rotate, thereby moving the position of the side sealing box. At the same time, the belt connecting assembly drives the auxiliary threaded column on the extension plate to rotate, causing the guide plate on the auxiliary threaded column to move. This makes it easier to adjust the position of the guide plate and the side sealing box according to the length of the plastic bottle. This allows for adjustment of the distance between the two side sealing boxes according to the length of the packaged plastic bottle, and allows the position of the guide plate to be adjusted synchronously, so that shorter plastic bottles can pass through the side sealing box for better heat sealing.

[0019] 2. The plastic bottle is pushed onto the packaging column, which in turn moves the feed tray. The packaging column then moves the bottle, which passes through the heat sealing shaft. The heat sealing shaft rotates, causing the fan blades and heat sealing strips to rotate. At the same time, the packaging paper roller and the lower packaging feed port provide packaging material to the heat sealing shaft. The packaging material is heat-sealed by the heat sealing strips. Simultaneously, the packaging material is cut by the cutting blade. The packaging material is cut and heat-sealed before the plastic bottle passes through the heat sealing shaft. After the plastic bottle enters between two packaging materials and passes through the heat sealing shaft again, the packaging material is cut and heat-sealed again, thus sealing the front and back of the packaging material. This makes it easier to heat-seal the plastic bottle.

[0020] 3. Qualified packaging plastic bottles are conveyed from the feeding table to the loading platform, with the bottle opening facing inward. The sensor detects that the packaging column and the packaging plastic bottle are aligned. At this time, the control platform receives the alignment information and activates the feeding telescopic column to push the packaging plastic bottle onto the packaging column. The packaging plastic bottle then pushes the infeeding tray to move. After completing the first step of sealing, it continues to move. Once it reaches the set position, the infeeding tray will cooperate with the trapezoidal ejection plate to push the packaging plastic bottle out of the packaging column and onto the conveyor. This makes it easier for the packaging plastic bottle to enter and exit the packaging column and prevents the trapezoidal ejection plate from damaging the packaging plastic bottle and packaging material during pushing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Please see Figures 1-6This invention provides a technical solution: an automatic packaging machine and method for bearing plastic bottles, comprising a packaging body 1, a feeding table 2 placed on one side of the packaging body 1, a conveying track 3 provided on the packaging body 1, multiple packaging columns 4 installed inside the conveying track 3, a loading platform 35 fixedly installed on the packaging body 1, and the feeding table 2 and the loading platform 35 cooperating with each other, a heat sealing assembly fixedly installed on the packaging body 1, a conveyor 11 placed on the other side of the packaging body 1, and the conveyor 11 located below the packaging columns 4, L-shaped mounting plates 14 fixedly installed on both sides of the conveyor 11, movable packaging assemblies fixedly installed on the L-shaped mounting plates 14, the movable packaging assembly including a main threaded column 15 rotatably mounted on the L-shaped mounting plate 14, a guide column 16 fixedly mounted on the L-shaped mounting plate 14, two side sealing boxes 17 mounted on the main threaded column 15, and the side sealing boxes 17 and the guide column 16 being rotatably connected, a conveying roller 13 rotatably mounted on the conveyor 11, and two side sealing boxes 17 being rotatably connected to the guide column 16, and a conveying roller 13 rotatably mounted on the conveyor 11. The side assembly box 17 and the main threaded post 15 are respectively fixedly installed and screw-installed. Each of the two side assembly boxes 17 has a receiving trough 23 and a heat sealing channel 27 on opposite sides, with the receiving trough 23 communicating with the heat sealing channel 27. The upper wall of the heat sealing channel 27 has an installation groove 24, inside which a rotating shaft 25 is rotatably installed. A heat sealing disc 26 is rotatably installed on the rotating shaft 25, and the heat sealing disc 26 can extend into the heat sealing channel 27 and cooperate with it. The main threaded post 15 penetrates one side. An L-shaped mounting plate 14 is provided. A power plate 18 is fixedly installed at one end of the main threaded post 15 that passes through the L-shaped mounting plate 14. An extension plate 20 is fixedly installed on the side of the L-shaped mounting plate 14 near the packaging body 1. An auxiliary threaded post 21 is rotatably installed on the extension plate 20.

A belt connection group 19 is fixedly installed between the auxiliary threaded post 21 and the main threaded post 15.

[0031] Specifically, the conveyor 11 is used for conveying. The guide plate 22 guides the conveyed plastic bottles 6, allowing the packaging materials on both sides to enter the heat sealing channel 27 through the receiving chute 23. This causes the rotating shaft 25 to drive the heat sealing disc 26 to rotate. As the packaging materials pass through the heat sealing channel 27, the heat sealing disc 26 heat-seals the packaging materials on both sides of the plastic bottles 6, thus completing the packaging. When the lengths of the plastic bottles 6 are different, the power disc 18 can be rotated, driving the main threaded column 15 to rotate, thereby achieving side sealing. The position of box 17 is moved, and at the same time, the belt connecting group 19 drives the auxiliary threaded post 21 on the extension plate 20 to rotate, causing the guide plate 22 on the auxiliary threaded post 21 to move. This makes it easier to adjust the position of the guide plate 22 and the side box 17 according to the length of the packaged plastic bottle 6. This allows the distance between the two side boxes 17 to be adjusted according to the length of the packaged plastic bottle 6, and the position of the guide plate 22 to be adjusted synchronously, so that the shorter packaged plastic bottle 6 can pass through the side box 17 for better packaging and heat sealing.

The heat sealing assembly includes two heat sealing shafts 7 rotatably installed on the packaging body 1, and the two heat sealing shafts 7 pass through the packaging column 4. Connecting gears 8 are fixedly installed on the two heat sealing shafts 7, and the connecting gears 8 mesh with each other. Multiple fan blades 9 are fixedly installed on the two heat sealing shafts 7, and the two fan blades 9 form a group. Heat sealing strips 30 are fixedly installed on each of the multiple fan blades 9.

[0034] Specifically, the plastic bottle 6 is pushed onto the packaging column 4, which in turn pushes the infeed disc 29 to move. Then, the packaging column 4 moves the plastic bottle 6 and it passes through the heat sealing shaft 7. At this time, the heat sealing shaft 7 rotates, which drives the fan blade 9 and the heat sealing strip 30 to rotate. Meanwhile, the packaging paper roller 33 and the lower packaging feed port 34 provide packaging material to the heat sealing shaft 7. The packaging material is heat-sealed by the heat sealing strip 30. At the same time, the packaging material is cut by the cutting blade 31.

After the plastic bottle 6 enters between the two packaging materials and passes through the heat sealing shaft 7, the packaging material is cut and heat-sealed again, so that the packaging material is sealed from front to back. This makes it easier to heat-seal the plastic bottle 6.

[0035] Example 3:

[0036] Please see Figures 1-6 This invention provides a technical solution: an automatic packaging machine and method for bearing plastic bottles. A feeding table 2 is placed on one side of the packaging body 1. A conveying track 3 is provided on the packaging body 1. Multiple packaging columns 4 are installed inside the conveying track 3. A feeding platform 35 is fixedly installed on the packaging body 1, and the feeding table 2 and the feeding platform 35 cooperate with each other.

[0037] Specifically, qualified plastic bottles 6 are conveyed to the loading platform 35 via the feeding table 2, with the bottle openings facing inwards. Sensor 5 detects that the packaging column 4 and the plastic bottle 6 are aligned. At this time, the control platform transmits the alignment information and activates the feeding telescopic column 12 to push the plastic bottle 6 onto the packaging column 4. The plastic bottle 6 then pushes the infeeding tray 29 to move. After completing the first step of packaging, it continues to move. After moving to the set position, the infeeding tray 29 will cooperate with the trapezoidal ejection plate 10, and then push the plastic bottle 6 out of the packaging column 4 and fall onto the conveyor 11. This makes it easier for the plastic bottle 6 to enter and exit the packaging column 4 and prevents the trapezoidal ejection plate 10 from damaging the plastic bottle 6 and packaging material during pushing.

[0038] Working principle: First, qualified plastic bottles 6 are conveyed to the loading platform 35 via the feeding table 2, with the bottle openings facing inwards. Sensor 5 detects that the packaging column 4 and the plastic bottle 6 are aligned. At this time, the control platform transmits the alignment information, and the control platform activates the feeding telescopic column 12 to push the plastic bottle 6 onto the packaging column 4. The plastic bottle 6 then pushes the infeed / outfeed disc 29 to move. Then, the packaging column 4 drives the plastic bottle 6 to move, and then it passes through the heat sealing shaft 7. At this time, the heat sealing shaft 7 rotates, driving the fan blades 9 and... The heat sealing strip 30 rotates, and at this time, the packaging paper roller 33 and the lower packaging feed port 34 provide packaging material to the heat sealing shaft 7. The packaging material is heat-sealed by the heat sealing strip 30. At the same time, the slitting blade 31 cuts the packaging material. Before the plastic bottle 6 passes through the heat sealing shaft 7, the packaging material is cut and heat-sealed. After the plastic bottle 6 enters between the two packaging materials and passes through the heat sealing shaft 7, the packaging material is cut and heat-sealed again, sealing the front and back of the packaging material. Then the packaging column 4 continues to drive the packaging... The plastic bottle 6 moves, and when it reaches the set position, the forward and backward plate 29 will cooperate with the trapezoidal unloading plate 10 to push the packaged plastic bottle 6 out of the packaging column 4 and fall onto the conveyor 11. Then, the conveyor 11 will transport it. At this time, the guide plate 22 will guide the transported packaged plastic bottle 6. Then, the packaging materials on both sides will enter the heat sealing channel 27 through the receiving chute 23, and the rotating shaft 25 will drive the heat sealing plate 26 to rotate. When the packaging materials pass through the heat sealing channel 27, the heat sealing plate 26 will heat seal the packaging materials on both sides of the packaged plastic bottle 6, thereby completing the packaging. When the length of the packaged plastic bottle 6 is different, the power plate 18 can be rotated, which will drive the main thread column 15 to rotate, thereby moving the position of the side sealing box 17. At the same time, the belt connecting group 19 will drive the auxiliary thread column 21 on the extension plate 20 to rotate, causing the guide plate 22 on the auxiliary thread column 21 to move. This makes it easier to adjust the position of the guide plate 22 and the side sealing box 17 according to the length of the packaged plastic bottle 6.

When the packaging material passes through the heat sealing channel (27), the heat sealing plate (26) is used to heat seal the packaging material on both sides of the bearing plastic bottle (6) to complete the packaging. When the length of the bearing plastic bottle (6) is different, the power plate (18) can be rotated to drive the main thread column (15) to rotate, thereby moving the position of the side sealing box (17). At the same time, the belt connecting group (19) drives the auxiliary thread column (21) on the extension plate (20) to rotate, causing the guide plate (22) on the auxiliary thread column (21) to move, so as to more conveniently adjust the position of the guide plate (22) and the side sealing box (17) according to the length of the bearing plastic bottle (6).
