Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling and processing, in particular to a waste plastic recycling and processing device. Background Art

[0002] Plastic refers to a material that has resin (or direct polymerization of monomers during processing) as the main component and additives such as plasticizers, fillers, lubricants and colorants as auxiliary components. It can flow and form during the processing process. Plastic is a synthetic polymer compound that can change its shape freely.

[0003] Polyethylene terephthalate (PET) is a commonly used plastic material for mineral water bottles and beverage bottles. This material is made of TPA (terephthalic acid) and EG (ethylene glycol) and is a pure polymer material. After the mineral water or beverage in the mineral water bottle and beverage bottle is consumed, the mineral water bottle and beverage bottle become waste plastic.

[0004] Specifically, waste plastics are a general term for plastics that have been used in civil, industrial and other purposes and eventually eliminated or replaced. They can be divided into recycled plastics, reprocessed plastics, recycled plastics, reusable plastics, recyclable plastics, and non-recyclable plastics according to different ways of reuse.

[0005] As is known, in order to protect the bottle body and prevent the bottle body from being scratched or worn during transportation and storage, a wrapping paper is usually provided on the plastic bottle body, and detailed information of the mineral water can be printed on the wrapping paper. The wrapping paper can also play a certain decorative role, increasing the aesthetics of the product.

[0006] There are many plastic bottle recycling devices in the prior art, such as the Chinese patent with application number 202211402895.2, authorization publication (announcement) number: CN115447023B, and the name of a waste plastic bottle recycling and processing equipment. The listed patent discloses a waste plastic bottle recycling and processing equipment, including a processing box, a cutting and cleaning mechanism, a drying barrel and a drying mechanism. The processing box is fixed by a fixed frame, and a feed port and a discharge port are provided on the processing box; the cutting and cleaning mechanism includes two rotating shafts rotatably connected in the processing box, and the rotating shafts are symmetrically arranged along the length direction of the processing box. Two guide rollers located between the two rotating shafts are rotatably connected in the processing box, and the two guide rollers are arranged obliquely downward along the length direction of the processing box. The two guide rollers and the rotating shaft close to the discharge port are arranged in a triangle. In the above patent, the recycled plastic bottles are cut by the cutting and cleaning mechanism, so that the air and liquid in the plastic bottles are discharged, avoiding the problem that the gas in the plastic bottles is difficult to discharge and the inconvenience caused to the compression of the plastic bottles occurs.

[0007] Another example is the Chinese patent with application number 202223472553.6, authorization publication (announcement) number: CN219788936U, and the name is a plastic bottle recycling pretreatment device. The above patent discloses a plastic bottle recycling pretreatment device, which belongs to the field of environmental protection equipment manufacturing technology, including: a base body, which is provided with a recycling box and a feeding port; a pushing mechanism, which includes a pushing seat, a pushing head, a pushing rod and a pushing handle; a main cutting mechanism. In the above patent, after the plastic bottle is put into the feeding port, the pushing handle is pushed to drive the pushing head to push the bottom of the plastic bottle so that the bottle mouth of the plastic bottle is stuck in the bottle mouth positioning column, and the cutting knife pressure rod is rotated to push the main cutting knife to cut the bottle body of the plastic bottle. The rotating disk can be driven to make the bottle mouth positioning column drive the bottle mouth of the plastic bottle to make a spiral motion and move away from the bottle body, thereby realizing the wire drawing pretreatment of the plastic bottle body.

[0008] In the prior art such as the above-mentioned patent, the recycling efficiency of waste plastic recycling equipment can be improved to a certain extent. It is known that although plastic bottles and wrapping paper are both made of plastic materials, they belong to different types of plastic materials if broken down. Therefore, when recycling specific waste plastics, plastic bottles and wrapping paper cannot be shared. For this reason, when recycling waste plastic bottles, it is necessary to separate the wrapping paper from the plastic bottles and recycle them separately to avoid affecting the subsequent recycling of waste plastics. However, in the prior art such as the above-mentioned patent, it is difficult to separate the plastic bottles from the wrapping paper during the waste plastic recycling operation, which affects the subsequent recycling and reuse of waste plastics; and when the equipment is running, in the prior art such as the above-mentioned patent, a separate transmission mechanism is usually used to transmit the waste plastics, and the waste plastics are unloaded after being transmitted to the predetermined station, which will lead to an increase in production costs.

[0009] It can be seen that how to separate the packaging paper from the plastic bottles on a single device and then passively transfer the discarded plastic bottles is an urgent problem that needs to be solved. Summary of the invention

[0010] The purpose of the present invention is to provide a waste plastic recycling and processing device to solve the problems raised in the above background technology.

[0014] Furthermore, the bearing part includes a bearing plate fixedly connected to the mounting frame, and a sliding plate is slidably connected to the mounting frame, a positioning spring is arranged between the sliding plate and the bearing plate, and the elastic force of the positioning spring drives the sliding plate and the bearing plate to approach each other to fix the bottle body.

[0015] Furthermore, the passive driving part includes an annular plate rotatably connected to the carrying plate, and the bottle body abuts against the annular plate; and a spur gear is installed on the annular plate, and a long rack is slidably connected to the mounting frame through a reset member, and the spur gear is meshed with the long rack; a trigger part is provided between the separation rod and the long rack; when the separation rod slides and the packaging paper is clamped through the winding groove, the long rack is driven to slide through the trigger part during the separation rod's continued sliding stroke, and the bottle body is driven to rotate through the cooperation between the spur gear and the annular plate, so that the bottle body is separated from the packaging paper.

[0016] Furthermore, the power component includes a power rod rotatably connected to the frame, multiple sets of driving gears are installed on the power rod, and a driving rack adapted to the driving gear is fixedly connected to the bottom of the mounting frame, and each driving gear is respectively engaged with the corresponding driving rack; the intermittent linkage mechanism is arranged between the driving shaft of the servo motor and the power rod.

[0017] Furthermore, the intermittent linkage mechanism includes a linkage plate and a connecting rod, and the connecting rod is coaxially connected to the servo motor through a synchronizer; a plurality of groups of ratchets are rotatably connected to the connecting rod, and a torsion spring is provided on each of the ratchets and the connecting rod; the linkage plate is fixedly connected to the power rod, and a plurality of groups of tooth grooves are provided on the linkage plate, and the elastic force of the torsion spring drives the ratchets to engage in the tooth grooves.

[0018] Furthermore, a recycling box connected to the support frame is arranged on the frame, and a passive material discharge part is arranged on the frame; during the sliding stroke of the mounting frame, the bearing part abuts against the passive material discharge part so that the bearing part unlocks the bottle body, so that the bottle body falls into the recycling box.

[0020] Furthermore, a discharge port is provided on the recycling box, and a squeezing mechanism for squeezing the bottle body into the recycling box is slidably connected inside the recycling box; the squeezing mechanism is connected to the driving block, and when the driving block drives the separation rod to slide, the bottle body inside the recycling box is squeezed by the squeezing mechanism; the squeezing mechanism includes an squeezing block slidably connected inside the recycling box, and the squeezing block is connected to the driving block through a power frame.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the waste plastic recycling and processing device, through the cooperation among the frame, the mounting frame, the bearing part, the separation structure, the power parts, the servo motor and the intermittent linkage mechanism, during use, when the servo motor drive shaft rotates forward, the separation mechanism drives the packaging paper to be separated from the bottle body. Therefore, during the stroke when the separation mechanism separates the packaging paper from the bottle body, the mounting frame at this moment will not slide on the support frame. Therefore, the separation mechanism can easily tear off the packaging paper on the bottle body without causing motion interference, thus meeting the working needs.

[0022] When the servo motor drive shaft reverses, the separation mechanism is driven to reset so that the packaging paper is separated from the separation mechanism. The intermittent linkage mechanism drives the power member to drive the mounting frame to slide on the frame to achieve the transmission operation of the peeled bottle body. That is, after the packaging paper on a bottle body is torn off, the servo motor starts to reverse. At this moment, the separation mechanism starts to slide in the opposite direction with the packaging paper on the bottle body. During the separation mechanism reset stroke, the servo motor drive shaft at this moment also passively drives the power member to move through the intermittent linkage mechanism. The power member drives the mounting frame to slide on the frame to achieve the transmission operation of the peeled bottle body, so that the bottle body with the packaging paper torn off can be transported to the next station, greatly improving the practicality of the entire recycling and processing device.

[0023] It can be seen that during the use of the waste plastic recycling and processing device, there is no need to set up a separate power source to drive the bottle body for conveying operations. Instead, the forward and reverse rotation of the motor can be fully utilized to separate the packaging paper from the bottle body and then convey the separated bottle body to the next workstation. The kinetic energy of the servo motor can be fully utilized while improving work efficiency. There is no need to set up a complex program to control the power source, which is convenient for later inspection and maintenance and can also save costs. It is suitable for wide promotion and use.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-18The present invention provides a technical solution: a waste plastic recycling and processing device, comprising a frame 1 and a support frame 2 installed on the frame 1, a mounting frame 3 is slidably connected to the support frame 2 through a power piece 7, and a plurality of bearing parts 4 for fixing a bottle body 5 are arranged on the mounting frame 3, wherein a packaging paper 6 is sleeved on the bottle body 5; a separation mechanism for driving the packaging paper 6 to separate from the bottle body 5 is arranged on the frame 1, a servo motor 8 for driving the separation mechanism to move is arranged on the frame 1, and the servo motor 8 and the power piece 7 are connected by an intermittent linkage mechanism 12 for transmission; during the working process, in the first station: when the driving shaft of the servo motor 8 rotates forward, the packaging paper 6 is driven to separate from the bottle body 5 through the separation mechanism; in the second station: when the driving shaft of the servo motor 8 is reversed, the separation mechanism is driven to reset so that the packaging paper 6 is separated from the separation mechanism, and the power piece 7 is driven by the intermittent linkage mechanism 12 to drive the mounting frame 3 to slide on the frame 1, so as to realize the transmission operation of the peeled bottle body 5.

[0046] Specifically, the waste plastic recycling and processing device includes a frame 1 and a support frame 2 installed on the frame 1. Multiple groups of support members are arranged on the frame 1, and anti-skid pads are also arranged on the bottom of the support members, so as to improve the stability of the processing device during operation. At the same time, multiple groups of heat sinks are also arranged on the frame 1 to perform heat dissipation operations. Specifically, a mounting frame 3 is slidably connected to the support frame 2 through a power member 7. A transverse groove is provided on the frame 1, and convex strips are provided on both sides of the mounting frame 3, and the convex strips are slidably connected in the transverse groove. Therefore, during use, when the power member 7 mounting frame 3 slides on the support frame 2, the convex strips at this moment will slide on the support frame 2 to improve the stability of the mounting frame 3 when it slides.

[0047] The mounting frame 3 is provided with multiple groups of bearing parts 4 for fixing the bottle body 5, wherein the number of bearing parts 4 is multiple and can be set according to work needs. The bottle body 5 is covered with a wrapping paper 6, and in order to improve the stability of the wrapping paper 6 when connected to the bottle body 5, adhesive is applied to the contact position between the inside of the wrapping paper 6 and the bottle body 5, so as to further improve the stability of the wrapping paper 6 when it is covered on the bottle body 5, and avoid the separation of the wrapping paper 6 and the bottle body 5 when the bottle body 5 is transported under normal circumstances.

[0048] The frame 1 is provided with a separation mechanism for driving the packaging paper 6 to separate from the bottle body 5. Therefore, when in use, the packaging paper 6 is separated from the bottle body 5 by the separation mechanism so that the bottle body 5 and the packaging paper 6 can be recycled separately. Therefore, there is no need to tear the packaging paper 6 off the bottle body 5 manually, which will not affect the recycling of plastics in the future, greatly improving the practicality of the plastic recycling and processing device and meeting work needs. The frame 1 is provided with a servo motor 8 for driving the separation mechanism to move, providing power for the operation of the separation mechanism.

[0049] The servo motor 8 is connected to the power piece 7 through an intermittent linkage mechanism 12, that is, when the servo motor 8 rotates forward, it will not drive the power piece 7 to move, and therefore will not drive the mounting frame 3 to slide on the support frame 2, thereby facilitating the tearing off of the wrapping paper 6 on the bottle body 5. When the driving shaft of the servo motor 8 is reversed, it will be connected to the power piece 7 at this moment, and the mounting frame 3 will be driven by the power piece 7 to slide on the support frame 2, so that the bottle body 5 with the wrapping paper 6 torn off can be transported to the next station, thereby greatly improving the practicality of the entire recycling and processing device.

[0050] To this end, two workstations are generated by the forward and reverse rotation of the servo motor 8:

[0051] First station: When the driving shaft of the servo motor 8 rotates forward, the separation mechanism drives the wrapping paper 6 to separate from the bottle body 5. Therefore, during the process of the separation mechanism separating the wrapping paper 6 from the bottle body 5, the mounting frame 3 at this moment will not slide on the supporting frame 2. Therefore, the separation mechanism can easily tear off the wrapping paper 6 from the bottle body 5 without causing motion interference, thus meeting the working requirements.

[0052] Second station: When the servo motor 8 driving shaft reverses, the separation mechanism is driven to reset so that the packaging paper 6 is separated from the separation mechanism. The power member 7 is driven by the intermittent linkage mechanism 12 to drive the mounting frame 3 to slide on the frame 1 to realize the transmission operation of the peeled bottle body 5. That is, after the packaging paper 6 on a bottle body 5 is torn off, the servo motor 8 starts to reverse, and at this moment, the separation mechanism starts to slide in the opposite direction with the packaging paper 6 on the bottle body 5. During the separation mechanism reset stroke, the servo motor 8 driving shaft at this moment also passively drives the power member 7 to move through the intermittent linkage mechanism 12, and the power member 7 drives the mounting frame 3 to slide on the frame 1 to realize the transmission operation of the peeled bottle body 5, so that the bottle body 5 with the packaging paper 6 torn off can be transported to the next station, which greatly improves the practicality of the entire recycling and processing device. To this end, during the use of the waste plastic recycling and processing device, there is no need to set up a separate power source to drive the bottle body 5 to perform the conveying operation. Instead, the forward and reverse rotation of the motor can be fully utilized to separate the packaging paper 6 from the bottle body 5 and then convey the separated bottle body 5 to the next workstation. The kinetic energy of the servo motor 8 can be fully utilized while improving work efficiency. There is no need to set up a complex program to control the power source, which is convenient for later inspection and maintenance and can also save costs. The device is suitable for wide promotion and use.

[0053] In the embodiment provided by the present invention, the separation mechanism includes a separation part 9, and the separation part 9 includes a separation rod 9.1 slidably connected to the frame 1, wherein a through slot is provided on the frame 1, and the separation rod 9.1 is slidably connected to the frame 1 through the through slot. A separation blade 9.2 is fixedly connected to the separation rod 9.1 through a connecting frame 9.3, and a winding slot 9.4 is also provided on the separation rod 9.1, and the servo motor 8 drives the separation rod 9.1 to slide through the driving unit 10. Specifically, during use, when the servo motor 8 drives the separation rod 9.1 to slide through the drive unit 10, the separation rod 9.1 will drive the separation blade 9.2 to contact the packaging paper 6 on the bottle body 5 during the sliding stroke. As the separation rod 9.1 continues to slide, the separation blade 9.2 will cut a notch in the packaging paper 6. At this moment, the packaging paper 6 with the notch cut will be in an unfolded state after there is no tension. At this time, when the separation rod 9.1 continues to slide, the winding groove 9.4 on the separation rod 9.1 will be clamped on the packaging paper 6 to meet the working needs.

[0054] In the embodiment provided by the present invention, specifically, the driving unit 10 includes a screw rod 10.1 rotatably connected to the frame 1, and a driving block 10.2 is slidably connected to the frame 1, wherein a plurality of sets of limiting telescopic rods are arranged between the driving block 10.2 and the frame 1, so as to improve the stability of the driving block 10.2 when sliding. The separation rod 9.1 is fixedly connected to the driving block 10.2, the screw rod 10.1 is threadedly connected to the driving block 10.2, and the servo motor 8 drives the screw rod 10.1 to rotate through the synchronous member 11. Specifically, the synchronous member 11 includes a first synchronous wheel 11.2 installed on the screw rod 10.1, and a second synchronous wheel 11.3 is arranged on the power member 7, and the first synchronous wheel 11.2 and the second synchronous wheel 11.3 are meshed through the synchronous belt 11.1. Therefore, during use, when the servo motor 8 is started, the screw rod 10.1 is driven to rotate through the cooperation of the synchronous member 11. When the screw rod 10.1 rotates, it drives the driving block 10.2 to slide horizontally, and the driving block 10.2 drives the separation rod 9.1 to slide. A passive driving part 13 is also arranged between the bearing part 4 and the mounting frame 3. During the travel when the driving block 10.2 drives the winding groove 9.4 on the separation rod 9.1 to clamp the packaging paper 6, the bottle body 5 is driven to rotate through the passive driving part 13, so that the packaging paper 6 is separated from the bottle body 5. Therefore, when the separation rod 9.1 drives the separation blade 9.2 to completely cut the wrapping paper 6 during its sliding stroke, the winding groove 9.4 at this moment will clamp the wrapping paper 6. Since the wrapping paper 6 is bonded to the bottle body 5 by glue, the screw rod 10.1 continues to drive the separation rod 9.1 to slide through the driving block 10.2. When the separation rod 9.1 continues to slide, it will drive the passive driving part 13 to move, and the bottle body 5 will be driven to rotate through the passive driving part 13. When the bottle body 5 rotates, the wrapping paper 6 is passively driven to wrap around the separation rod 9.1, so that the bottle body 5 can be separated from the wrapping paper 6. A recycling frame 19 is provided on the frame 1, so when the separation rod 9.1 is reset, the separation rod 9.1 slides inside the through slot. When the separation rod 9.1 passes through the through slot, the tension of the wrapping paper 6 itself is in an "expanded" state, so the wrapping paper 6 cannot pass through the through slot smoothly. Instead, when the separation rod 9.1 slides inside the through slot, the wrapping paper 6 is blocked and stops moving until it is completely separated from the separation rod 9.1, and the wrapping paper 6 falls on the recycling frame 19 to achieve the recycling of the wrapping paper 6. To put it another way, even if the wrapping paper 6 does not fall accurately into the recycling frame 19 due to factors such as gravity, it does not matter, as long as the wrapping paper 6 is separated from the bottle body 5.

[0055] In the embodiment provided by the present invention, the bearing part 4 includes a bearing plate 4.1 fixedly connected to the mounting frame 3, and a sliding plate 4.2 is slidably connected to the mounting frame 3, and a positioning spring 4.4 is provided between the sliding plate 4.2 and the bearing plate 4.1, and the elastic force of the positioning spring 4.4 drives the sliding plate 4.2 and the bearing plate 4.1 to approach and fix the bottle body 5. Specifically, a limiting groove 4.5 is provided on the mounting frame 3, and guide blocks 4.3 are fixedly connected on both sides of the sliding plate 4.2, wherein the guide blocks 4.3 are slidably connected in the limiting groove 4.5, thereby improving the stability of the sliding plate 4.2 when sliding. In the original state, the elastic force of the positioning spring 4.4 drives the sliding plate 4.2 to approach the bearing plate 4.1, fixes the bottle body 5, and meets the working needs.

[0056] In the embodiment provided by the present invention, the passive driving part 13 includes an annular plate rotatably connected to the bearing plate 4.1. Similarly, an annular plate is also rotatably connected to the sliding plate 4.2 to reduce friction. Therefore, after the bottle body 5 abuts against the annular plate, when the annular plate rotates, the bottle body 5 can be driven to rotate. A spur gear 13.2 is installed on the annular plate, and a long rack 13.3 is slidably connected to the mounting frame 3 through a reset member 13.5. The spur gear 13.2 is meshed with the long rack 13.3. Therefore, when the long rack 13.3 slides, it drives the spur gear 13.2 to rotate, and the rotating rod 13.1 is driven to rotate through the spur gear 13.2 to meet the working needs. The reset member 13.5 includes a reset groove provided on the mounting frame 3, a reset block 13.51 is fixedly connected to the bottom of the long rack 13.3, the reset block 13.51 is slidably connected in the reset groove, and a reset spring 13.52 is installed between the reset groove and the reset block 13.51, and the long rack 13.3 maintains a predetermined position under the elastic action of the reset spring 13.52. A trigger part 13.4 is provided between the separation rod 9.1 and the long rack 13.3, that is, after the separation rod 9.1 slides to a predetermined position, the long rack 13.3 is passively slid by the trigger part 13.4, so there is no need to separately set a driving source to drive the long rack 13.3 to slide, further improving the practicality of the recycling and processing device. When the separation rod 9.1 slides and clamps the packaging paper 6 through the winding groove 9.4, the separation rod 9.1 continues to slide and drives the long rack 13.3 to slide through the trigger part 13.4, and drives the bottle body 5 to rotate through the cooperation between the spur gear 13.2 and the annular plate, so that the bottle body 5 is separated from the packaging paper 6. Specifically, the trigger part 13.4 includes a trigger groove 13.41 provided on the side wall of the long rack 13.3, and the separation rod 9.1 is fixedly connected to the trigger rod 13.42 through a connecting plate. In actual use, when the separation rod 9.1 slides to a predetermined position (i.e., the separation blade 9.2 cuts the packaging paper 6 axially and the winding groove 9.4 clamps the packaging paper 6), the trigger rod 13.42 abuts against the trigger groove 13.41. When the trigger rod 13.42 continues to slide, it drives the long rack 13.3 to slide, passively drives the spur gear 13.2 to rotate, and the packaging paper 6 is torn off the bottle body 5. Preferably, the transmission ratio between the long rack 13.3 and the spur gear 13.2 is set according to the working needs to ensure that the packaging paper 6 can be smoothly torn off the bottle body 5.

[0057] In the embodiment provided by the present invention, the power member 7 includes a power rod 7.3 rotatably connected to the frame 1, a plurality of drive gears 7.2 are installed on the power rod 7.3, and a drive rack 7.1 adapted to the drive gear 7.2 is fixedly connected to the bottom of the mounting frame 3, and each drive gear 7.2 is respectively meshed with the corresponding drive rack 7.1; the intermittent linkage mechanism 12 is arranged between the drive shaft of the servo motor 8 and the power rod 7.3, specifically, the second synchronous wheel 11.3 is installed on the drive shaft of the servo motor 8, and the intermittent linkage mechanism 12 is installed between the second synchronous wheel 11.3 and the power rod 7.3, so that the servo motor 8 intermittently drives the power rod 7.3 to rotate, thereby meeting the working needs. The intermittent linkage mechanism 12 includes a linkage plate 12.2 and a connecting rod 12.1, and the connecting rod 12.1 is coaxially connected to the servo motor 8 through the synchronous member 11, and specifically, the connecting rod 12.1 is fixedly connected to the second synchronous wheel 11.3. The connecting rod 12.1 is rotatably connected to multiple groups of ratchets 12.4, each ratchets 12.4 and the connecting rod 12.1 are provided with a torsion spring, the linkage plate 12.2 is fixedly connected to the power rod 7.3, and the linkage plate 12.2 is provided with multiple groups of tooth grooves 12.5, and the elastic force of the torsion spring drives the ratchets 12.4 to be clamped in the tooth grooves 12.5. Specifically, the back of the ratchets 12.4 is in an arc shape to meet the working requirements. The connecting rod 12.1 is fixedly connected to multiple groups of bases 12.3, and each ratchets 12.4 is rotatably connected to the connecting rod 12.1 through the bases 12.3.

[0058] Therefore, during use, when the servo motor 8 rotates forward, the cooperation between the second synchronous wheel 11.3 and the synchronous belt 11.1 drives the first synchronous wheel 11.2 to rotate, and then drives the driving screw 10.1 to rotate. When the screw 10.1 rotates, it drives the driving block 10.2 to slide horizontally, and drives the separation rod 9.1 to slide through the driving block 10.2. During the sliding stroke, the separation rod 9.1 drives the separation blade 9.2 to contact the packaging paper 6 on the bottle body 5. As the separation rod 9.1 continues to slide, the separation blade 9.2 cuts a notch in the packaging paper 6. At this moment, the packaging paper 6 with the notch cut has no tension and will be in an unfolded state. At this time, when the separation rod 9.1 continues to slide, the winding groove 9.4 on the separation rod 9.1 will be clamped on the packaging paper 6. When the separation rod 9.1 slides to a predetermined position (that is, after the separation blade 9.2 cuts the packaging paper 6 axially and the winding groove 9.4 clamps the packaging paper 6), the trigger rod 13.42 abuts against the trigger groove 13.41. When the trigger rod 13.42 continues to slide, it will drive the long rack 13.3 to slide, passively drive the spur gear 13.2 to rotate, and tear the packaging paper 6 from the bottle body 5. During the above operation, when the driving shaft of the servo motor 8 drives the second synchronous wheel 11.3 to rotate, the second synchronous wheel 11.3 drives the connecting rod 12.1 to rotate. When the connecting rod 12.1 rotates, the ratchet 12.4 is driven to rotate through the base 12.3. The arc-shaped back side of the ratchet 12.4 abuts against the tooth groove 12.5, so it cannot drive the linkage plate 12.2 to rotate, and further cannot drive the power rod 7.3 to rotate, so that the mounting frame 3 is in a stationary state.

[0059] When the servo motor 8 is reversed, the drive screw 10.1 is driven to rotate through the synchronous member 11, and the separation rod 9.1 is driven to reset, meeting the working needs. At this time, when the second synchronous wheel 11.3 drives the connecting rod 12.1 to rotate, the latching teeth on the connecting rod 12.1 will be engaged with the tooth groove 12.5. When the latching teeth rotate, the linkage plate 12.2 will inevitably be driven to rotate, thereby driving the power rod 7.3 to rotate. When the power rod 7.3 rotates, the driving gear 7.2 and the driving rack 7.1 cooperate to drive the mounting frame 3 to slide on the support frame 2, meeting the working needs, so as to realize the transmission operation of the peeled bottle body 5, so that the bottle body 5 with the packaging paper 6 torn off can be transported to the next station, greatly improving the practicality of the entire recycling and processing device.

[0060] In the embodiment provided by the present invention, a recycling box 14 connected to the support frame 2 is provided on the frame 1, and a passive unloading member 17 is provided on the frame 1, so that the unloading operation of the bottle body 5 can be realized passively, and there is no need to separately set up an unlocking mechanism to unlock the bottle body 5, which can further achieve the effect of saving costs. In the sliding stroke of the mounting frame 3, the bearing part 4 is in contact with the passive unloading member 17 so that the bearing part 4 unlocks the bottle body 5, so that the bottle body 5 falls into the recycling box 14, which is convenient for recycling the bottle body 5 separated from the packaging paper 6, meeting the work needs.

[0061] In the embodiment provided by the present invention, specifically, the passive unloading member 17 includes a contact block 17.1 fixedly connected to the support frame 2, and an adapting groove 17.2 adapted to the contact block 17.1 is provided on the sliding plate 4.2, wherein the contact block 17.1 and the adapting groove 17.2 are both wedge-shaped, which facilitates driving the sliding plate 4.2 to slide, and the use effect is better. When the adapting groove 17.2 abuts against the contact block 17.1, the sliding plate 4.2 overcomes the elastic force of the positioning spring 4.4 and slides away from the bearing plate 4.1, unlocking the bottle body 5 so that the bottle body 5 enters the inside of the recycling box 14, so as to realize the collection operation of the bottle body 5, further improving the practicality of the recycling and processing device and meeting the work needs.

[0062] As is known, after the bottle body 5 is recovered, it is usually necessary to flatten it to avoid occupying a large space.

[0063] In another embodiment provided by the present invention, a discharge port 18 is provided on the recycling box 14. Specifically, the discharge port 18 is small, and only the flattened bottles 5 can fall out through the discharge port 18. More specifically, the interior of the recycling box 14 is tilted, and the bottom of the recycling box 14 is relatively smooth. In the absence of external force factors, the bottles 5 placed in the recycling box 14 will slide obliquely downward due to factors such as gravity.

[0064] In this embodiment, a squeezing mechanism 15 for squeezing a body into the recycling box 14 is slidably connected inside the recycling box 14. The squeezing mechanism 15 is connected to the driving block 10.2. When the driving block 10.2 drives the separation rod 9.1 to slide, the bottle body 5 inside the recycling box 14 is squeezed by the squeezing mechanism 15. Specifically, the squeezing mechanism 15 includes a squeezing block 15.2 slidably connected inside the recycling box 14, and the squeezing block 15.2 is connected to the driving block 10.2 through a power frame 15.5. A connecting block 15.1 is also slidably connected inside the recycling box 14, wherein the power frame 15.5 is fixedly connected to the connecting block 15.1, and the connecting block 15.1 is slidably connected to the squeezing block 15.2 through a vertical rod 15.3, wherein the number of the vertical rods 15.3 can be multiple to improve the stability of the power block and the connecting block 15.1 when sliding. A guide component is provided between the extrusion block 15.2 and the recycling box 14, wherein the guide component comprises a guide rod 16.1 fixedly connected to the extrusion block 15.2, a guide groove 16 with an inclined output end is provided on the side wall of the recycling box 14, and the guide rod 16.1 slides inside the guide groove 16. An installation groove is provided on the inner wall of the recycling box 14, wherein the extrusion block 15.2 and the connection block 15.1 are both slidably connected inside the installation groove. At the same time, when the driving block 10.2 drives the separation rod 9.1 to slide into the stroke of separating the packaging paper 6, the power frame 15.5 drives the connection block 15.1 to slide, and the vertical rod 15.3 drives the extrusion block 15.2 to slide during the sliding stroke of the connection block 15.1. The extrusion block 15.2 begins to slide from top to bottom under the cooperation of the guide rod 16.1 and the guide groove 16, so as to better contact with the bottle body 5, thereby gradually squeezing the bottle body 5 and flattening the bottle body 5 so that it can slide out from the discharge port 18, which is convenient for the subsequent recycling of the bottle body 5 and has a better use effect. In this process, no driving source is set to squeeze the bottle body 5, but the bottle body 5 entering the recycling box 14 is squeezed by driving the separation of the packaging paper 6 and the bottle body 5, which greatly improves the practicality of the recycling device and has a better use effect.

[0065] The present invention also provides another embodiment, in which an adhesive layer 15.4 is provided at the bottom of the extrusion block 15.2. After the extrusion block 15.2 extrudes the bottle body 5, the friction between the bottle body 5 and the bottom of the recycling box 14 increases due to the large pressure, so that the bottle body 5 cannot be discharged smoothly through the discharge port 18. By providing the adhesive layer 15.4, when the extrusion block 15.2 starts to reset after extruding the bottle body 5, the adhesive layer 15.4 will slide the bottle body 5 upward together, so that the flattened bottle body 5 is away from the bottom of the recycling box 14. When the power frame 15.5 drives the connecting block 15.1 to slide inside the installation groove, the flattened bottle body 5 will be blocked by the recycling box 14 and separated from the adhesive layer 15.4, so that it will fall to the bottom of the recycling box 14 again. At this time, because the bottom of the recycling box 14 is inclined, the flattened bottle body 5 can be discharged smoothly through the discharge port 18. Specifically, the material of the extrusion block 15.2 is set according to the work needs, which can ensure that the bottle body 5 can be flattened once.
