Description

Technical Field

[0001] The present application relates to the technical field of baling machines, and in particular to a plastic bottle baling machine. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use PET, PE, and PP as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and blow-molded, extruded, or injection-molded plastic containers through plastic molds. Waste plastic bottles need to be recycled and transported, and often require plastic bottle balers.

[0003] A Chinese patent with application number CN202222152296.1 discloses a plastic bottle baler, including a base box, a mounting plate fixedly connected to the left side of the upper end of the base box, a mounting box fixedly connected to the left side of the upper end of the base box on one side of the mounting plate, and the mounting box and the mounting plate are both connected to the base box. The present application adopts the above structure, and the present application places the discarded plastic bottles inside the base box, and then compresses them by a material pressing mechanism to reduce the volume for better collection and utilization. During the compression process, the first compacting component will contact the second compacting component, and the feeding plate will be driven to slightly push the plastic bottle under the action of the second spring in the second compacting component, and then the second cylinder will be started to drive the second moving plate to move the feeding plate again, and then the blocking component will be operated, so that the compressed and packaged plastic bottles can be pushed out, avoiding the situation where the manual unloading operation is cumbersome and the work intensity is high, resulting in extended recycling time and reduced plastic bottle recycling efficiency.

[0004] When the plastic bottle baler in the above patent is in use, since there will be residual liquid in the waste plastic bottles, although the plastic bottles will be squeezed during the baler extrusion process, there will be residual liquid in a large number of plastic bottles, which will cause the plastic bottles to be less compact when compressed and packaged. If the compactness is low, it will result in a ton loss.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects.

Obviously, the described embodiments are partial embodiments of the present application, rather than all embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] like Figures 1 to 7 As shown, the present application provides a plastic bottle packaging machine, comprising: a machine body 1, a pre-treatment mechanism for processing plastic bottles before packaging, and a packaging mechanism for packaging the processed plastic bottles.

[0034] Since there will be residual liquid in the waste plastic bottles, although the plastic bottles will be squeezed during the extrusion process of the baler, there will be residual liquid in a large number of plastic bottles, which will cause the plastic bottles to have low compactness when compressed and packaged. If the compactness is low, it will lead to a loss of tons. Therefore, the plastic bottles need to be processed by a pre-treatment mechanism and then packaged by a packaging mechanism.

[0035] The pretreatment mechanism includes: a treatment box 11 fixedly installed on the body 1, a filter screen 28 fixedly installed in the treatment box 11, a material guiding component for guiding plastic bottles into the treatment box 11, and a piercing component for piercing the plastic bottles entering the treatment box 11; a feed opening is opened on the treatment box 11, and the feed opening is connected to the body 1.

[0036] The piercing assembly includes: a roller 12 rotatably installed in a processing box 11, the roller 12 is provided with two driving gears 15 coaxially connected to the roller 12, the two driving gears 15 are mutually meshingly arranged and fixedly installed on the roller 12, a conical piercing rod 13, a motor 14 driving the roller 12 to rotate, the motor 14 is fixedly installed on the processing box 11, and the output shaft of the motor 14 is coaxially connected to any one of the rollers 12, and a cleaning unit is used to clean the conical piercing rod 13.

[0037] When the material guide assembly guides the plastic bottle into the processing box 11, the motor 14 is started to drive the roller 12 coaxially connected to its output shaft to rotate, and synchronously drives the adjacent driving gear 15 to rotate. Since the two driving gears 15 are meshed with each other, the two rollers 12 are relatively rotated, and the conical piercing rod 13 is driven to rotate through the two rollers 12, so that the plastic bottle can be pierced and the pierced plastic bottle can fall downward between the two groups of rollers 12.

[0038] The punctured plastic bottle falls onto the filter screen 28. Since the plastic bottle has holes, the air or residual liquid in the plastic bottle is discharged through the holes when squeezed. Through the setting of the filter screen 28, the residual liquid in the plastic bottle can be filtered, and the residual liquid flows into the bottom of the inner cavity of the processing box 11.

[0039] Since the filter screen 28 is arranged at an angle, the filtered plastic bottles slide from the top of the filter screen 28 to the feed opening, and enter the machine body 1 through the feed opening, so as to be ready for subsequent packaging.

[0040] In the present application, a plastic bottle can be punctured by a puncturing assembly. Since the plastic bottle is punctured with holes, air or residual liquid in the plastic bottle is discharged through the holes when squeezed, thereby improving the compactness of the plastic bottle when it is compressed and packaged.

[0041] The cleaning unit comprises: a cleaning roller 17 rotatably mounted in the processing box 11, a steel brush 18 fixedly mounted on the cleaning roller 17, and a driven gear 16 coaxially connected to the cleaning roller 17; the driven gear 16 and the driving gear 15 are meshed with each other.

[0042] When the driving gear 15 rotates, the adjacent driven gear 16 can be driven to rotate, thereby driving the two cleaning rollers 17 to rotate, and the two cleaning rollers 17 drive the steel brush 18 to rotate. Through the rotation of the steel brush 18, on the one hand, the impurities attached to the surface of the conical piercing rod 13 can be cleaned to ensure the piercing effect of the conical piercing rod 13 on the plastic bottle, and on the other hand, the plastic bottle stuck on the conical piercing rod 13 can be pushed off, avoiding the plastic bottle stuck on the conical piercing rod 13 from rotating with the conical piercing rod 13 and affecting the normal use of the conical piercing rod 13, further ensuring the piercing effect of the conical piercing rod 13 on the plastic bottle.

[0043] The material guide assembly includes: a material guide plate 22 hingedly installed in the processing box 11, and a linkage unit for driving the material guide plate 22 to vibrate; the linkage unit includes: a cam 21 rotatably installed in the processing box 11, a driven pulley 20 coaxially connected to the cam 21, a driving pulley 19 coaxially connected to the cleaning roller 17, a linkage belt 30 installed between the driving pulley 19 and the driven pulley 20, and a reset member for driving the material guide plate 22 to reset; the reset member includes: a mounting shell 23 fixedly installed in the processing box 11, a slider 24 slidably installed in the mounting shell 23, a linkage rod 26 hingedly installed between the slider 24 and the material guide plate 22, a guide rod 27 for guiding the slider 24, and a reset spring 25 for driving the material guide plate 22 to reset; one end of the reset spring 25 is fixedly connected to the slider 24, and the other end of the reset spring 25 is fixedly connected to the inner wall of the mounting shell 23; the guide rod 27 passes through the side wall of the slider 24, and both ends of the guide rod 27 are fixedly installed in the mounting shell 23.

[0044] The plastic bottle is put into the processing box 11 from the top opening, and the motor 14 is started at this time, which drives the active pulley 19 to rotate. The active pulley 19 drives the driven pulley 20 to rotate through the linkage belt 30, and then drives the cam 21 to rotate. When the cam 21 rotates and squeezes the guide plate 22, the guide plate 22 is driven to rotate at its hinge with the processing box 11, and the guide plate 22 drives the linkage rod 26 to move. The linkage rod 26 drives the slider 24 to slide in the mounting shell 23 and drives the reset spring 25 to deform. When the cam 21 is separated from the guide plate 22, the slider 24 is reset by the elastic force of the reset spring 25, and the slider 24 drives the linkage rod 26 to reset, and then drives the guide plate 22 to reset. Through the mutual cooperation of the cam 21 and the reset unit, the guide plate 22 vibrates, thereby driving the plastic bottles to shake, and then it is convenient to guide the plastic bottles between the two rollers 12, avoiding the problem that too many plastic bottles are easily accumulated and stuck between the two guide plates 22, thereby improving the feeding efficiency.

[0045] The packaging mechanism includes: a pressing plate 3 movably installed in the machine body 1, a hydraulic rod 2 for driving the pressing plate 3 to move, a baffle 4 fixedly installed on the machine body 1 and movably installed on the machine body 1, a hydraulic rod 2 5 for driving the baffle 4 to move, a hydraulic rod 2 5 fixedly installed on the machine body 1 and a limiting component for limiting the baffle 4 when moving, a push plate 8 movably installed on the machine body 1, a hydraulic rod 3 9 for driving the push plate 8 to move, a hydraulic rod 3 9 fixedly installed on the machine body 1 and a fixed plate 10 fixedly installed in the machine body 1; a plurality of through holes are opened on the fixed plate 10.

[0046] The punctured plastic bottles enter the machine body 1 and fall on the top of the fixed plate 10. When a certain amount of plastic bottles gather on the top of the fixed plate 10, the pretreatment mechanism stops running, and the plastic bottles are stopped from being transported into the machine body 1.

[0047] At the same time, the hydraulic rod 2 is started to drive the pressing plate 3 to move downward, and cooperate with the fixed plate 10, the baffle 4, and the push plate 8 to realize the compression and packaging of the plastic bottles. Although the plastic bottles are filtered by the filter net 28, there may still be residual liquid in the plastic bottles. In the process of compressing the plastic bottles, the air or residual liquid in the plastic bottles is fully discharged through the holes, so that the compactness of the compression is further improved when the plastic bottles are compressed and packaged.

[0048] The residual liquid squeezed out of the plastic bottle flows into the bottom of the inner cavity of the body 1 through the through holes on the fixing plate 10 .

[0049] When the plastic bottles are packed, start the hydraulic rod 1 2 to drive the pressure plate 3 to reset upward, and start the hydraulic rod 2 5 to drive the baffle 4 to move upward. The limit assembly can limit the movement of the baffle 4. The limit assembly includes: a slide rail 7 fixedly installed on the machine body 1, and a sleeve 6 slidably installed on the slide rail 7; the sleeve 6 is fixedly connected to the baffle 4; that is, the baffle 4 drives the sleeve 6 to slide along the slide rail 7, thereby improving the stability of the baffle 4 during movement. In addition, during the compression process of the plastic bottles, the cooperation between the sleeve 6 and the slide rail 7 can limit the baffle 4 to prevent the plastic bottles from squeezing the baffle 4, causing the baffle 4 to move, and then causing the hydraulic rod 2 5 to be damaged.

[0050] When the baffle 4 moves to the required height, the baffle 4 no longer has a shielding effect on the packaged plastic bottles. At this time, the hydraulic rod three 9 is started to drive the push plate 8 to push the packaged plastic bottles out of the machine body 1, without manual removal, thereby improving work efficiency. After the packaged plastic bottles are moved out, the hydraulic rod two 5 and the hydraulic rod three 9 are started again to drive the baffle 4 and the push plate 8 to reset respectively, so as to prepare for subsequent use.

[0051] It also includes: a water pump 29; the water inlet end of the water pump 29 is connected to the body 1 and the processing box 11 through a water inlet pipe, and the water outlet end of the water pump 29 is connected to a water outlet pipe.

[0052] By starting the water pump 29, the residual liquid in the treatment box 11 and the residual liquid in the machine body 1 can be discharged to prepare for subsequent use.

The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art.
