Description

Technical Field

[0001] This application relates to the field of glass recycling equipment, and more particularly to a broken glass feeding device. Background Technology

[0002] In the existing glass bottle production process, the raw materials used to make glass bottles usually include three main categories: basic raw materials, auxiliary raw materials, and recycled glass. Among them, waste glass bottles recycled in daily life and waste glass bottles recycled in production are sorted, cleaned, crushed and then recycled in the furnace. The waste glass bottles are melted down and added to the glass raw material for making glass bottles, which can reduce the loss of raw materials in glass bottle production, thereby reducing production costs and meeting the environmental protection requirements and sustainable development concept of resource reuse.

[0003] After the waste glass bottles undergo sorting and crushing processes, the broken glass pile will contain a large amount of waste paper and metal bottle caps. Before entering the calcination furnace for reprocessing, the waste paper and bottle caps need to be removed to ensure the production quality of the glass bottles.

[0004] In existing technologies, waste paper is typically removed by air blowing, while bottle caps are typically removed by magnetic attraction. However, since broken glass may stack during transport on the conveyor line, if waste paper or bottle caps are pressed between the stacked broken glass, it is difficult to remove them using only air blowing and magnetic attraction. As a result, some waste paper or bottle caps still flow into the subsequent calcination process, which affects the forming quality of the glass bottles and needs to be improved. Utility Model Content

[0005] Based on this, this application provides a broken glass feeding device that can improve the rejection effect of waste paper and bottle caps and reduce the possibility of waste paper or bottle caps flowing to subsequent processes.

[0006] The broken glass feeding device provided in this application adopts the following technical solution: A broken glass feeding device includes a first conveying mechanism, a material transfer mechanism, a turnover screening mechanism, and a second conveying mechanism arranged sequentially along the broken glass conveying direction. The material transfer mechanism includes a mechanism box and a blowing assembly. The mechanism box has a material discharge channel inside, and the blowing assembly is arranged inside the material discharge channel to remove waste paper. The side of the mechanism box has an inlet chute and an outlet chute, both of which are connected to the material discharge channel. The end of the first conveying mechanism is directly opposite the inlet chute. The turnover screening mechanism includes a rotating screen cylinder and a drive assembly for driving the rotating screen cylinder to rotate. The rotating screen cylinder has a turnover cavity inside, which is directly opposite the discharge chute. A magnetic suction rod assembly is coaxially arranged inside the turnover cavity, which is used to remove bottle caps. The second conveying mechanism is located directly below the rotating screen cylinder and is used to receive broken glass that passes through the mesh structure on the surface of the rotating screen cylinder.

[0007] By adopting the above technical solution, waste glass bottles are crushed into shredded glass. The shredded glass is conveyed on the first conveying mechanism and enters the discharge channel of the mechanism box through the infeed chute when passing through the discharge transfer mechanism. Due to the different weights of glass of different sizes, the shredded glass falls downwards in the discharge channel and can separate from each other. At the same time, under the action of the air blowing component, the waste paper can be scattered upwards and separated from the shredded glass pile. This method can greatly reduce the occurrence of waste paper being pressed down by shredded glass and reduce the possibility of waste paper flowing into subsequent processes. Then, the shredded glass falls into the turnover chamber of the rotating screen cylinder through the discharge chute of the discharge channel. The rotating screen cylinder can rotate circumferentially around its own central axis under the drive component, so that the locally stacked shredded glass is flipped by force. The metal bottle caps contained in the shredded glass can be attracted by the magnetic suction rod group and separated from the shredded glass pile, thereby achieving effective removal of bottle caps and reducing the possibility of bottle caps flowing into subsequent processes.

[0008] Optionally, the material discharge channel runs through the upper and lower sides of the mechanism box, and a negative pressure pipe is connected to the top of the material discharge channel. A negative pressure generator is connected to the negative pressure pipe. A baffle is installed at the junction of the material discharge channel and the discharge chute, and the baffle has ventilation holes. The blowing assembly includes an axial flow fan fixed at the bottom of the material discharge channel.

[0009] By adopting the above technical solution, after the broken glass enters the discharge channel through the feed inlet, it can fall onto the baffle, slide down along the baffle, pass through the discharge chute, and fall into the rotating screen cylinder. As the axial flow fan continuously blows positive pressure air into the discharge channel, the positive pressure air blows upward and carries the waste paper, which can make the waste paper enter the negative pressure pipe and be collected, so as to achieve effective removal of waste paper.

[0010] Optionally, the material discharge channel is inclined downwards towards the discharge chute.

[0011] By adopting the above technical solution, and by setting the feeding pipe to be inclined downward, the speed at which the glass moves downward when it enters the feeding channel can be slowed down, so that the blowing assembly has enough time to blow the waste paper out of the glass and reduce the possibility of the waste paper flowing to the subsequent process.

[0012] Optionally, a structural support is fixedly mounted above the second conveying mechanism, and the rotating screen cylinder is rotatably mounted on the structural support; the driving component includes a gear ring plate fixed to the outer circumference of the rotating screen cylinder, a servo motor fixed to the structural support, and a drive gear connected to the output shaft of the servo motor, with the drive gear and the gear ring plate meshing and transmitting power to each other.

[0013] By adopting the above technical solution, the operation of the servo motor is controlled to drive the drive gear to rotate. The drive gear can force the meshing gear ring plate to rotate, thereby causing the rotating screen cylinder to rotate circumferentially around its own central axis. During the rotation of the screen cylinder, the broken glass that enters the turnover cavity can pass through the mesh structure on the outer circumference of the rotating screen cylinder and fall into the second conveying mechanism. The bottle caps inside the broken glass can be attracted to the magnetic suction rod group under the action of magnetic attraction, thereby achieving effective removal of bottle caps.

[0014] Optionally, the magnetic suction rod assembly includes a magnetic column fixedly mounted inside the turnover cavity and a plastic scraper rotatably mounted on the outer periphery of the magnetic column. The plastic scraper is spirally arranged, and a linkage structure is provided between the plastic scraper and the output shaft of the servo motor to force the plastic scraper to rotate.

[0015] By adopting the above technical solution, when the bottle cap is attracted to the magnetic column by magnetic attraction, the plastic scraper rotates with the drive component through the linkage structure. The plastic scraper can carry the bottle cap to one end of the magnetic column, reducing the occurrence of large accumulation of bottle caps in local positions.

[0016] Optionally, the axial length of the plastic scraper is greater than the axial length of the magnetic column, so that the magnetic suction rod assembly has a magnetic suction section and a non-magnetic section. The structural support is equipped with a collection box for receiving bottle caps, and a guide plate is mounted on the top of the collection box. The guide plate is located directly below the transition position between the magnetic suction section and the non-magnetic section.

[0017] By adopting the above technical solution, the bottle cap gradually moves from the magnetic section to the non-magnetic section under the action of the plastic scraper. After the bottle cap finally moves to the non-magnetic section, it can automatically fall into the collection box, thereby realizing the automatic collection of bottle caps and reducing the possibility of a large number of bottle caps accumulating on the surface of the magnetic rod assembly.

[0018] Optionally, the linkage structure includes a driven gear fixedly connected to one end of the plastic scraper and a linkage gear fixed to the output shaft of the servo motor. The outer periphery of the driven gear and the linkage gear are jointly fitted with a transmission belt.

[0019] By adopting the above technical solution, the driven gear and the linkage gear are driven by a transmission belt. When the servo motor operates and drives the rotating screen cylinder to rotate circumferentially, the plastic scraper can rotate together. There is no need to set up a separate drive source, which has the advantages of energy saving and consumption reduction.

[0020] Optionally, the broken glass feeding device also includes a circulating conveying mechanism located outside the second conveying mechanism. The rotating screen cylinder is inclined downwards away from the mechanism box, and a discharge port is provided on the side of the rotating screen cylinder away from the mechanism box. The circulating conveying mechanism is located directly below the discharge port.

[0021] By adopting the above technical solution, when the broken glass enters the rotating screen cylinder, the smaller broken glass can pass through the mesh structure on the outer circumference of the rotating screen cylinder and fall to the second conveying mechanism, while the larger broken glass that cannot pass through the mesh structure can fall from the discharge port of the rotating screen cylinder onto the circulating conveying mechanism. The circulating conveying mechanism can send the larger broken glass back to the crushing process for further crushing.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a material transfer mechanism, the broken glass can enter the material drop channel of the mechanism box from the feed chute when it passes through the material transfer mechanism. The broken glass falls downward in the material drop channel and can be separated from each other. At the same time, under the action of the air blowing component, the waste paper can be scattered upward and separated from the broken glass pile, which greatly reduces the occurrence of waste paper being pressed down by broken glass and reduces the possibility of waste paper flowing into the subsequent process. 2. By setting up a turnover screening mechanism, the broken glass enters the turnover cavity of the rotating screen cylinder. Under the drive of the drive component, the rotating screen cylinder can rotate around its own central axis, causing the locally stacked broken glass to be flipped by force. The metal bottle caps contained in the broken glass can be attracted and removed from the broken glass pile by the magnetic suction rod group, thereby achieving effective removal of bottle caps and reducing the possibility of bottle caps flowing into the subsequent process. 3. By setting up a plastic scraper, the plastic scraper rotates under the drive of the drive component, which can carry the bottle caps adsorbed on the surface of the magnetic column and move them from the magnetic section to the non-magnetic section. Finally, after the bottle caps move to the non-magnetic section, they can automatically fall into the collection box, realizing the automatic collection of bottle caps and reducing the possibility of a large number of bottle caps accumulating on the surface of the magnetic rod assembly.

Detailed Implementation

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0026] This application discloses a broken glass feeding device.

[0027] Reference Figure 1 A glass crushing device includes a first conveying mechanism 1, a material transfer mechanism 2, a turnover screening mechanism 3, a second conveying mechanism 4, and a circulating conveying mechanism 5. The first conveying mechanism 1, the second conveying mechanism 4, and the circulating conveying mechanism 5 are all configured with conveyor belts. The first conveying mechanism 1 is used to receive the glass crushing pile obtained after the previous crushing process and to transport the glass crushing pile to the material transfer mechanism 2.

[0028] Reference Figure 2 The material transfer mechanism 2 includes a mechanism box 21 and a blowing assembly 22. The mechanism box 21 is fixedly installed on the ground foundation. A material dropping channel 211 is opened inside the mechanism box 21, which runs through the upper and lower sides of the mechanism box 21. A material inlet trough 212 connected to the material dropping channel 211 is opened on the side of the mechanism box 21. The end of the first conveying mechanism 1 is directly opposite the material inlet trough 212 and is partially located inside the material inlet trough 212, which can convey broken glass into the material inlet trough 212.

[0029] The side of the mechanism box 21 is also provided with a discharge chute 213 that communicates with the discharge channel 211. The discharge chute 213 and the inlet chute 212 are respectively provided on two opposite sides of the mechanism box 21. In this embodiment, the discharge channel 211 is inclined downward towards the discharge chute 213 to slow down the speed at which broken glass falls downward in the discharge channel 211. A baffle 23 is installed at the junction of the discharge channel 211 and the discharge chute 213. The surface of the baffle 23 is provided with a breathable mesh 231. The baffle 23 can catch the broken glass falling downward and allow the broken glass to enter the discharge chute 213.

[0030] The blowing assembly 22 is an axial flow fan located at the bottom of the material discharge channel 211. When the axial flow fan is operating, it can continuously blow positive pressure air into the material discharge channel 211. A negative pressure pipe 24 is installed at the top of the mechanism box 21. The negative pressure pipe 24 is connected to the material discharge channel 211, and a negative pressure generator (not shown in the figure) is connected to the end of the negative pressure pipe 24 away from the mechanism box 21. This generator can continuously draw air into the material discharge channel 211, thus ensuring that there is always an upward airflow inside the material discharge channel 211. When the broken glass moves downward in the material discharge channel 211, the waste paper contained in the broken glass can float upward under the action of the wind and is eventually collected by the negative pressure generator, achieving effective removal of waste paper.

[0031] Reference Figure 3 The turnover screening mechanism 3 includes a structural support 33, a rotating screen cylinder 31, and a drive assembly 32. The structural support 33 is fixedly mounted above the second conveying mechanism 4. A freely rotatable support wheel 331 is fixed to the top of the structural support 33. A convex ring plate 311 is fixed to the outer circumferential surface of the rotating screen cylinder 31, and the convex ring plate 311 can abut against the support wheel 331 and limit its movement. (See also...) Figure 2 A turnover cavity 312 is provided in the middle of the rotating screen cylinder 31. The turnover cavity 312 extends through both end faces of the rotating screen cylinder 31, and one end of the turnover cavity 312 is directly opposite the discharge chute 213. The baffle 23 inside the discharge channel 211 extends partially into the turnover cavity 312, so that the broken glass can enter the inside of the turnover cavity 312 along the baffle 23 after leaving the discharge chute 213.

[0032] Reference Figure 4 The drive assembly 32 includes a gear ring plate 321, a drive gear 322, and a servo motor 323. The gear ring plate 321 is fixed to the outer circumferential surface of the rotating screen cylinder 31, and is located at the end of the rotating screen cylinder 31 away from the mechanism housing 21. The servo motor 323 is fixedly mounted on the structural support 33, and the drive gear 322 is coaxially fixed to the output shaft of the servo motor 323. The drive gear 322 and the convex teeth of the gear ring plate 321 mesh with each other for transmission. Based on this, when the servo motor 323 is controlled to operate, the drive gear 322 can drive the gear ring plate 321 to rotate, so that the rotating screen cylinder 31 can rotate circumferentially around its own central axis.

[0033] Back Figure 3It should be noted that in this embodiment, the rotating screen cylinder 31 is inclined downwards away from the mechanism box 21. The rotating screen cylinder 31 includes a screen part 313 and two solid parts 314 respectively disposed at both ends of the screen part 313. The second conveying mechanism 4 is disposed directly below the screen part 313 of the rotating screen cylinder 31. When the broken glass enters the turnover cavity 312, it will first be located inside the solid part 314. Then, as the rotating screen cylinder 31 rotates, the broken glass gradually moves towards the screen part 313. Smaller broken glass can fall onto the second conveying mechanism 4 through the mesh structure of the screen part 313, while larger broken glass can be intercepted inside the rotating screen cylinder 31.

[0034] In addition, return Figure 4 The side of the rotating screen cylinder 31 away from the mechanism box 21 serves as the discharge port 315, and the circulating conveying mechanism 5 is located directly below the discharge port 315. As the rotating screen cylinder 31 rotates, larger pieces of glass can gradually move towards the discharge port 315. Eventually, the pieces of glass leave the discharge port 315 and fall onto the circulating conveying mechanism 5. The circulating conveying mechanism 5 can then send the larger pieces of glass back to the crushing process for further crushing.

[0035] Inside the turnover cavity 312, a magnetic suction rod assembly 6 for removing bottle caps is coaxially arranged. Specifically, the magnetic suction rod assembly 6 includes a magnetic column 61 and a plastic scraper 62. The magnetic column 61 is coaxially arranged inside the rotating sieve cylinder 31, and a plastic rod 63 is fixedly connected to the end of the magnetic column 61. The plastic rod 63 is fixedly connected to the structural support 33, thereby fixing the magnetic column 61 inside the rotating sieve cylinder 31 and realizing the installation of the magnetic column 61.

[0036] The plastic scraper 62 is rotatably sleeved on the outer periphery of the magnet post 61. In this embodiment, the axial length of the plastic scraper 62 is greater than the axial length of the magnet post 61, specifically equal to the sum of the lengths of the magnet post 61 and the plastic rod 63. Based on this, the section of the plastic scraper 62 sleeved on the magnet post 61 can serve as a magnetic attraction section 64, while the section of the plastic scraper 62 sleeved on the plastic rod 63 can serve as a non-magnetic section 65. A linkage structure 7 is provided between the plastic scraper 62 and the output shaft of the servo motor 323, so that the servo motor 323 can drive the plastic scraper 62 to rotate when it operates.

[0037] Simultaneously refer to Figure 4 Specifically, the linkage structure 7 includes a driven gear 71, a linkage gear 72, and a transmission belt 73. The driven gear 71 is fixed to the outer peripheral surface of the plastic scraper 62, while the linkage gear 72 is fixed to the output shaft of the servo motor 323. The transmission belt 73 is sleeved on the outer peripheral side of the driven gear 71 and the linkage gear 72, thereby enabling the driven gear 71 and the linkage gear 72 to rotate in the same direction and at the same speed.

[0038] The structural support 33 is fixed with a collection box 8 for receiving bottle caps. A guide plate 81 is provided on the side of the collection box 8, with the end of the guide plate 81 away from the collection box 8 located directly below the non-magnetic section 65. When broken glass enters the rotating screen cylinder 31 and the rotating screen cylinder 31 continues to rotate, smaller broken glass pieces fall onto the second conveyor line through the mesh structure of the screen section 313, while bottle caps contained in the broken glass can be attracted by the magnetic rod to achieve effective removal of bottle caps. As the servo motor 323 operates to drive the plastic scraper 62 to rotate, the plastic scraper 62 can push the bottle caps from the magnetic section 64 to the non-magnetic section 65. The bottle caps lose their magnetic attraction in the non-magnetic section 65 and can fall naturally downward onto the guide plate 81, thereby automatically collecting the bottle caps in the collection box 8 for easy cleaning.

[0039] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
