Description

Technical Field

[0001] The utility model relates to the technical field of recycled rubber processing, in particular to a rubber particle screening device. Background Art

[0002] Tires are circular elastic rubber products that are grounded and rolled on various vehicles or machines. Since waste tires are difficult to degrade, they cause soil fertility to decline and pollute soil and groundwater over a long period of time. Therefore, proper disposal of waste tires is very important for protecting the ecological environment. At present, the recycling of waste tires generally involves crushing the tires, and recycling the crushed rubber particles and rubber powder to make different rubber products. Since different rubber products have different requirements for the size of rubber, it is necessary to screen the crushed rubber particles to process them into different rubber products.

[0003] Current rubber particle screening devices usually operate with an inclined multi-stage screen frame. However, there are some problems in this process: since the discharge port is connected to the screen frame and the screen frame is inclined, the rubber particles tend to move toward the discharge port during the falling process. Sometimes, rubber particles that have not been fully screened are discharged from the discharge port. Especially on the lower screen frame, the rubber particles falling from the upper screen frame are unevenly distributed, causing them to scatter on the lower screen frame. This situation makes it easier for the rubber particles on the lower screen frame to be discharged directly through the discharge port, thus affecting the screening quality. Utility Model Content

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The rubber particle screening device according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the rubber particle screening device according to the embodiment of the utility model may include a box body 10 , a plurality of screen frames 20 , a cylinder body 30 , a plurality of dial plates 50 and a driving mechanism 70 .

[0024] A screening chamber 11 is provided inside the box body 10 , and an inlet 12 is opened at the top of the screening chamber 11 .

[0025] The screen frames 20 are arranged obliquely, and a plurality of screen frames 20 are arranged in the screening chamber 11 from top to bottom in sequence, and the diameters of the screen holes on the plurality of screen frames 20 decrease in sequence.

[0026] It is understandable that the rubber particles fall from the inlet 12 onto the upper screen frame 20 and are screened by the multiple screen frames 20 .

[0027] The cylinder 30 is arranged to penetrate the screening chamber 11 , and a rotating shaft 40 is vertically movably arranged inside the cylinder 30 . The driving mechanism 70 is arranged on the cylinder 30 , and one end of the rotating shaft 40 penetrates the box 10 and is connected to the driving mechanism 70 .

[0028] A plurality of discharge cavities 31 are arranged inside the cylinder 30 corresponding to the screen frame 20 , the rotating shaft 40 passes through the discharge cavity 31 , and a transfer port 311 and an outlet 312 are arranged on both symmetrical sides of the discharge cavity 31 , respectively, and the transfer port 311 is connected to the bottom end of the corresponding screen frame 20 .

[0029] A plurality of shift plates 50 are movably disposed in the corresponding screen frames 20 , and an arc-shaped baffle plate 60 for opening and closing the transfer port 311 is disposed on one side of the shift plate 50 . The arc-shaped baffle plate 60 is slidably disposed in the discharge chamber 31 , and one side of the arc-shaped baffle plate 60 is connected to the rotating shaft 40 through a connecting rod 61 , and one end of the shift plate 50 is slidably disposed on the other side of the arc-shaped baffle plate 60 .

[0030] It should be noted that the driving mechanism 70 described in this embodiment can drive the rotating shaft 40 to rotate, and can also manipulate the rotation direction and angle of the rotating shaft 40, so that the rotating shaft 40 drives the arc baffle 60 to rotate through the connecting rod 61, so that the arc baffle 60 slides in the transfer port 311. During the process, the paddle 50 can paddle the rubber particles in the screen frame 20 back and forth, thereby speeding up the screening rate and effectively avoiding the problem of blockage of the screen frame 20.

[0031] Specifically, in the actual process of screening the rubber particles, the relevant personnel first control the arc-shaped baffle 60 to block the transfer port 311 through the driving mechanism 70, and then drop the rubber particles from the inlet 12 onto the screen frame 20 above.

[0032] As the rubber particles move downward on the screen frame 20 , the rubber particles with small diameters fall through the screen holes of the screen frame 20 to continue to be screened on the lower screen frame 20 .

[0033] During the rubber particle screening process, relevant personnel can control the reciprocating rotation of the rotating shaft 40 through the driving mechanism 70 on the premise of blocking the transfer port 311, so that the paddle 50 can paddle the rubber particles in the screen frame 20 back and forth, thereby speeding up the screening rate and effectively avoiding the problem of blockage of the screen frame 20.

[0034] When the rubber particles are fully screened, relevant personnel can control the rotating shaft 40 through the driving mechanism 70 to drive the arc baffle 60 to rotate, so that the arc baffle 60 drives the paddle 50 to rotate to the side away from the outlet 312, and the transfer port 311 is opened. At this time, the remaining rubber particles in the screen frame 20 can enter the discharge chamber 31 through the transfer port 311, and finally be discharged from the corresponding outlet 312.

[0035] In one embodiment of the present invention, Figure 5 As shown, a groove 62 is provided on one side of the arc-shaped baffle 60, one end of the shift plate 50 is slidably disposed in the groove 62, and a spring 621 and a folding curtain 622 connected to the shift plate 50 are disposed in the groove 62, and the folding curtain 622 is disposed at the opening of the groove 62.

[0036] It is understandable that when the paddle 50 is driven by the rotating shaft 40 to slide in the groove 62, the folding curtain 622 can be folded along with the paddle 50, and the folding curtain 622 can cover the opening of the groove 62, thereby preventing rubber particles from entering the groove 62 and affecting the screening quality.

[0037] Specifically, during the process of the arc-shaped baffle 60 rotating and opening the transfer port 311, the paddle plate 50 is driven by the rotating shaft 40 to abut against one side of the screen plate, and then the rotating shaft 40 drives the arc-shaped baffle 60 to continue rotating. At this time, the spring 621 is compressed, and the folding curtain 622 is folded. The position of the paddle plate 50 on the arc-shaped baffle 60 moves relatively until the arc-shaped baffle 60 rotates and opens the transfer port 311.

[0038] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the driving mechanism 70 may include a driving component 72, a moving frame 73 and a gear 71, wherein the gear 71 is connected to the rotating shaft 40. The output end of the driving component 72 is horizontally connected to the moving frame 73. The moving frame 73 is movably arranged on the box body 10, and the first rack 731 and the second rack 732 are respectively arranged on the symmetrical inner side walls of the moving frame 73, and the first rack 731 and the second rack 732 are respectively arranged on the symmetrical sides of the gear 71, and the two can be meshed with the gear 71 in sequence.

[0039] It should be noted that the driving component 72 described in this embodiment can be a cylinder, a telescopic motor, etc. The driving component 72 can drive the moving frame 73 to move horizontally.

[0040] Under the premise that the arc-shaped baffle 60 blocks the transfer port 311, when the driving component 72 drives the moving frame 73 to move, the gear 71 engages with the first rack 731 and the second rack 732 in sequence. Since the first rack 731 and the second rack 732 are respectively arranged on the symmetrical sides of the gear 71, when the first rack 731 and the second rack 732 are respectively engaged with the gear 71, the rotation direction of the gear 71 changes, thereby enabling the rotating shaft 40 to drive the dial plate 50 to move back and forth.

[0041] When the transfer port 311 needs to be opened, the relevant personnel can control the movement of the moving frame 73 through the driving component 72, and make the gear 71 engage on the side of the first rack 731 away from the second rack 732. During the process, the rotating shaft 40 can drive the arc baffle 60 to rotate, and increase the rotation amplitude of the arc baffle 60 toward the side away from the outlet 312, thereby allowing the arc baffle 60 to open the transfer port 311.

[0042] In one embodiment of the present invention, Figure 1 As shown, a shock-absorbing base 13 is disposed at the bottom of the box 10 , and a vibration component 80 is disposed on the box 10 .

[0043] It should be noted that the vibration component 80 described in this embodiment may be a motor or a vibrator. The vibration force generated by the vibration component 80 can vibrate the box body 10, so that the multiple screen frames 20 can perform efficient vibration screening on the rubber particles.

[0044] In summary, the rubber particle screening device of the embodiment of the utility model drives the arc-shaped baffle plate to conveniently open and close the transfer port through the rotating shaft, thereby conveniently controlling the discharge of rubber particles and avoiding the discharge of unscreened rubber particles. In addition, the rotating shaft is set to toggle the rubber particles on the screen frame back and forth through the dial plate, thereby accelerating the screening rate and effectively avoiding the problem of blockage of the screen frame.
