Description

Technical Field

[0001] The invention belongs to the field of plastic bottle processing, and particularly relates to an automatic feeding and storage bin for plastic bottle flakes. Background Art

[0002] Plastic bottles are widely made from polyester (PET), polyethylene (PE), and polypropylene (PP) with the addition of appropriate organic solvents. After being heated to high temperatures, they are blow-molded, extruded, or injection-molded through plastic molds. They are primarily used for disposable packaging of liquids or solids, such as beverages, food, pickles, honey, dried fruits, cooking oil, and pesticides. Plastic bottles are characterized by their resistance to breakage, low cost, high transparency, and food-grade raw materials. As is well known, used plastic bottles can be recycled and reused. The recycling industry reflects a society's overall performance in waste sorting, waste recycling, environmental protection laws and regulations, policy support, and public awareness. Before recycling, plastic bottles need to be shredded into plastic flakes. After shredding, the shredded plastic bottle flakes are fed into a storage silo for future storage.

[0003] The existing method of feeding and storing crushed plastic bottle flakes is to manually carry the plastic bottle flakes to the feeding port and feed them into the storage bin manually. This method has a low degree of automation, is time-consuming and labor-intensive, and the storage bin is relatively high. When workers climb back and forth on ladders to feed the flakes, dangerous accidents are prone to occur, and the safety is low. Summary of the Invention

[0004] The object of the present invention is to provide an automated feeding and storage bin for plastic bottle flakes to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an automated feeding and storage bin for plastic bottle flakes, comprising: a storage bin and a conveyor, the upper end of the storage bin being circular in cross section and having an arc-shaped feeding port on the left side, a side groove being provided on one side of the feeding port, a sleeve being rotatably installed in the side groove, an arc plate being fixedly installed on the outer side of the sleeve shaft for sealing the feeding port, a mounting hole being provided in the middle of the upper end of the storage bin, a moving rod being provided in the mounting hole, the sleeve shaft being sleeved on the outer side of the moving rod, the inner wall of the sleeve shaft being uniformly distributed in the circumferential direction with five rotating grooves, the circumferential side of the moving rod being uniformly distributed in the circumferential direction with five rotating protrusions, the sleeve shaft being meshed with the moving rod, the upper end of the moving rod extending above the storage bin, the middle part of which being provided with a square groove, the external fixed sleeve being provided with a fixed plate, a plurality of springs being provided between the fixed plate and the storage bin, a T-shaped pillar being provided at one end of the conveyor, and the square groove being used to fix the T-shaped pillar.

[0006] As a preferred technical solution of the present invention, the side groove and the feeding port form a circular notch.

[0007] As a preferred technical solution of the present invention, the lower end of the moving rod extends into the storage bin, and a motor is fixedly installed thereon. The motor output shaft is fixedly linked to a rotating column, and the rotating column is circumferentially provided with external gear teeth. A dispersion plate is rotatably installed in the storage bin, and a plurality of dispersion holes are provided on the dispersion plate. A rotating column is fixedly provided in the middle of the upper end of the dispersion plate, and an inner groove is provided in the middle of the upper end of the rotating column. The inner groove is circumferentially provided with inner gear teeth, and the inner gear teeth are engaged with the outer gear teeth.

[0008] As a preferred technical solution of the present invention, an annular groove is provided on the inner wall of the storage bin, an annular support plate is fixed to the outside of the dispersion plate, and the support plate rotates in the annular groove.

[0009] As a preferred technical solution of the present invention, a plurality of balls are arranged in the annular groove, and the balls are in rolling contact with the bottom of the support plate.

[0010] As a preferred technical solution of the present invention, the cross section of the dispersion plate is arc-shaped.

[0011] As a preferred technical solution of the present invention, the arc surface of the arc plate is provided with a rubber strip.

[0012] As a preferred technical solution of the present invention, a material taking port is provided on one side of the storage bin.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention uses an automated feeding and storage bin for plastic bottle chips. The lower end of the T-shaped pillar is aligned with the square groove. The T-shaped pillar enters the square groove under the action of gravity to complete the fixation of one end of the conveyor. The fixation is convenient and quick. As gravity acts, the T-shaped pillar moves downward with the moving rod, and the spring contracts. As the moving rod and the sleeve shaft engage, the sleeve shaft rotates, and the arc plate rotates into the side groove, exposing the feeding port. At this time, the plastic bottle chips crushed by the crusher can be automatically fed into the storage bin along with the conveyor. There is no need to manually carry the plastic bottle chips. The degree of automation is high, efficiency is improved, and manpower is saved. There is no need for workers to climb back and forth in the storage bin, which is safe. There is no need to manually open the feeding port, which saves manpower.

[0015] 2. The automatic feeding and storage bin for plastic bottle chips of the present invention can be disassembled when feeding is completed and used on other storage bins to avoid damage to the conveyor when not in use for a long time, thereby improving utilization efficiency. When dismantling, as the T-shaped pillar is removed from the square groove, the fixed plate moves upward with the moving rod under the action of the spring, causing the sleeve shaft to rotate, and the arc plate blocks the feeding port again, effectively preventing fallen leaves and other debris from entering the storage bin and mixing with the plastic bottle chips, reducing the later cleaning time and improving work efficiency. Moreover, the feeding port of the present invention can only be opened when it is necessary to feed and store plastic bottle chips, that is, when the conveyor is installed and the T-shaped pillar is inserted into the square groove. The feeding port is automatically closed at all other times, which has a good isolation effect on debris such as leaves, and the opening and closing of the feeding port throughout the entire process are all caused by the gravity of the conveyor, without the need for a separate driving source, thus saving energy.

[0016] 3. The automated feeding and storage bin for plastic bottle chips of the present invention, when the moving rod moves downward, the rotating column enters the inner groove, the inner gear teeth and the outer gear teeth engage, the motor is started, and the motor drives the rotating column and the dispersion plate to rotate. The plastic bottle chips falling from the feeding port onto the dispersion plate rotate with the dispersion plate and fall evenly into the storage bin from the dispersion holes, effectively avoiding the concentrated accumulation of plastic bottle chips in a certain part of the storage bin, thereby improving the space utilization rate of the storage bin; and when the feeding is completed and the conveyor is completely disassembled, as the T-shaped pillar is removed from the square groove, the fixed plate moves upward with the moving rod under the action of the spring, the rotating column disengages from the inner groove, and the inner gear teeth and the outer gear teeth are no longer engaged. Even if the staff accidentally touches the motor control switch and causes the motor to work, it will not drive the dispersion plate to work, thereby effectively reducing the non-working wear of the inner gear and the outer gear.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] See also Figure 1-6In this embodiment, an automated feeding and storage bin for plastic bottle chips comprises: a bin 1 and a conveyor 2. The cross-section of the upper end of the bin 1 is circular, and an arc-shaped feeding port 4 is opened on the left side. A side groove 6 is provided on one side of the feeding port 4. A sleeve shaft 7 is rotatably installed in the side groove 6. An arc plate 5 for blocking the feeding port 4 is fixedly installed on the outer side of the sleeve shaft 7. A mounting hole is provided in the middle of the upper end of the bin 1. A moving rod 8 is provided in the mounting hole. The sleeve shaft 7 is sleeved on the outer side of the moving rod 8. Five rotating grooves are evenly distributed on the inner wall of the sleeve shaft 7 in the circumferential direction. Five rotating protrusions are evenly distributed on the circumferential side of the moving rod 8. The sleeve shaft 7 is engaged with the moving rod 8. The upper end of the moving rod 8 extends above the bin 1 and is provided with a square groove 11 in the middle. A fixed plate 9 is provided on the outer fixed sleeve. Several springs 10 are provided between the fixed plate 9 and the bin 1. A T-shaped pillar 3 is provided at one end of the conveyor 2. The square groove 11 is used to fix the T-shaped pillar 3.

[0029] In order to enable the arc plate 5 to rotate, the side groove 6 and the feeding port 4 form a circular notch.

[0030] Specifically, when it is necessary to store the crushed plastic bottle pieces, one end of the conveyor 2 is installed at the discharge port of the crusher, and the other end (including one end of the T-shaped support 3) is installed on the storage bin 1. During installation, it is only necessary to align the lower end of the T-shaped support 3 with the square groove 11. The T-shaped support 3 enters the square groove 11 under the action of gravity to complete the fixation of one end of the conveyor 2. The fixation is convenient and quick, and with the action of gravity, the T-shaped support 3 moves downward with the moving rod 8, and the spring 10 contracts. Because the moving rod 8 and the sleeve shaft 7 are engaged, the sleeve shaft 7 rotates, and the arc plate 5 rotates into the side groove 6 to expose the feeding port 4. At this time, the plastic bottle pieces crushed by the crusher can be automatically entered into the storage bin 1 along with the conveyor 2. There is no need to manually carry the plastic bottle pieces. The degree of automation is high, the efficiency is improved, and manpower is saved. There is no need for staff to climb back and forth in the storage bin, and the safety is high. The feeding port 4 is blocked by the spring 10 and the movable rod 8 is moved upward, so that the sleeve shaft 7 rotates, and the arc plate 5 blocks the feeding port 4 again, effectively preventing debris such as fallen leaves from entering the storage bin 1 and mixing with the plastic bottle chips, reducing the later cleaning time and improving the work efficiency. In addition, the feeding port 4 can be opened only when the plastic bottle chips need to be fed and stored, that is, the conveyor 2 is installed and the T-shaped pillar 3 is inserted into the square groove 11. The rest of the time, it is in an automatically closed state, which has a good isolation effect on debris such as leaves, and the opening and closing of the feeding port throughout the whole process are all caused by the gravity of the conveyor 2, without the need for a separate driving source, thus saving energy.

[0031] The lower end of the moving rod 8 extends into the storage bin 1, and a motor 12 is fixedly installed on it. The output shaft of the motor 12 is fixedly linked to a rotating column 13, and the rotating column 13 is circumferentially provided with external gear teeth 14. A dispersion plate 18 is rotatably installed in the storage bin 1, and a plurality of dispersion holes 19 are opened on the dispersion plate 18. A rotating column 15 is fixedly set in the middle of the upper end of the dispersion plate 18, and an inner groove 16 is opened in the middle of the upper end of the rotating column 15. The inner groove 16 is circumferentially provided with inner gear teeth 17, and the inner gear teeth 17 are engaged with the outer gear teeth 14.

[0032] The bottle flakes that fall from the feeding port 4 onto the dispersion plate 18 rotate along with the dispersion plate 18 and fall evenly into the storage bin 1 through the dispersion holes 19, effectively avoiding the accumulation of the plastic bottle flakes in a certain part of the storage bin 1, thereby improving the space utilization rate of the storage bin 1; and when the feeding is completed and the conveyor 2 is completely disassembled, as the T-shaped support 8 is removed from the square groove 11, the fixed plate 9 moves upward with the moving rod 8 under the action of the spring 10, the rotating column 14 disengages from the inner groove 16, and the inner gear 17 is no longer engaged with the outer gear 14. Even if the staff accidentally touches the motor control switch, causing the motor 12 to work, it will not drive the dispersion plate 18 to work, thereby effectively reducing the non-working wear of the inner gear 17 and the outer gear 14.

[0033] In order to provide support and rotation conditions for the spreading plate 18 , an annular groove 21 is opened on the inner wall of the storage bin 1 , and an annular support plate 20 is fixed to the outside of the spreading plate 18 , and the support plate 20 rotates in the annular groove 21 .

[0034] In order to reduce the friction of the dispersion plate 18 during rotation, a plurality of balls 22 are provided in the annular groove 21 , and the balls 22 are in rolling contact with the bottom of the support plate 20 .

[0035] The cross-section of the dispersion plate 18 is curved. Due to gravity, plastic bottle flakes that fall onto the dispersion plate 18 tend to gather toward the center, which facilitates their entry into the bottom of the storage bin through the dispersion holes 19. Furthermore, as the dispersion plate 18 rotates, the curved design causes the plastic bottle flakes to be scattered outward along the inner surface of the dispersion plate 18, further facilitating their entry into the bottom of the storage bin 1 through the dispersion holes 19.

[0036] The arc surface of the arc plate 5 is provided with a rubber strip 23 to enhance the isolation effect.

[0037] In order to facilitate material removal, a material removal port 24 is provided on one side of the storage bin 1 .

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
