Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a split-flow particle screening device of a bamboo powder biodegradable material granulator. Background Art

[0002] The particle screening device is an important component of the bamboo powder biodegradable material granulator. Its main function is to screen the granular materials produced by the granulator to meet the needs of different fields for granular materials.

[0003] Chinese patent CN222270896U discloses a particle screening device for a masterbatch granulator, which relates to the technical field of screening devices. The utility model includes a screening box, a screen plate is arranged in the screening box, an arc-shaped recess is arranged at one end of the screen plate, a transmission shaft is rotated in the arc-shaped recess, a plurality of crushing blades are symmetrically arranged on the side of the transmission shaft, a first servo motor for driving the transmission shaft to rotate is arranged on one side of the screening box, and a vibration motor is arranged on the upper side of the screening box. The masterbatch particles are screened through the screen plate and heated by a hot air mechanism to dry the masterbatch particles, the first servo motor is turned on to drive the crushing blade to rotate through the transmission shaft, and the crushing blade rotates to crush the masterbatch particles in the arc-shaped recess until the masterbatch particles are screened out through the arc-shaped recess, so as to improve the qualified rate of the screened masterbatch particles.

[0004] The above technology uses a sieve plate to screen the particulate material. Although it can effectively achieve separation, its working principle relies on the particulate material passing through the holes on the sieve plate. In this process, some particulate materials are close in size to the diameter of the sieve holes, which can easily cause the material to be blocked in the sieve holes, thereby reducing the screening efficiency. In addition, for larger-sized particulate materials, existing devices are usually equipped with crushing blades for cutting and crushing. Although the crushing blade can effectively reduce the particle size, dust is generated during the crushing process. The dust is mixed with the incompletely separated particulate materials, which not only pollutes the material, but also significantly reduces the accuracy and efficiency of screening.

[0028] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0029] See also Figures 1 to 10 As shown, a diversion type particle screening device of a bamboo powder biodegradable material granulator comprises a diversion screening mechanism installed inside a screening box 1, the diversion screening mechanism comprises an anti-blocking screening plate 3, a material receiving guide rail 4, a vibration knocking mechanism 5 and a synchronous transmission assembly 2; the anti-blocking screening plate 3 is installed inside the screening box 1, a material receiving bottom plate 37 is installed below the anti-blocking screening plate 3, and a movable diversion screen plate 36 is installed between the material receiving bottom plate 37 and the anti-blocking screening plate 3; a plurality of material receiving guide rails 4 are provided, and the material receiving guide rails 4 are installed at the discharge end of the material receiving bottom plate 37; the vibration knocking mechanism 5 is installed in the material receiving guide rail 4, and the working end of the vibration knocking mechanism 5 is in contact with the inner wall of the material receiving guide rail 4; the synchronous transmission assembly 2 is provided with a plurality of transmission ends, and the transmission ends of the synchronous transmission assembly 2 are respectively connected to the vibration knocking mechanism 5 and the movable diversion screen plate 36, and the input end of the synchronous transmission assembly 2 is connected to the driving source.

[0030] A hot air mechanism 11, a diverter rod 12, a transmission shaft 13 and a crushing blade 14 are also installed inside the screening box 1. The hot air mechanism 11, the diverter rod 12, the transmission shaft 13 and the crushing blade 14 are all arranged above the anti-blocking screening plate 3. The input end of the synchronous transmission assembly 2 is connected to the transmission shaft 13. The hot air mechanism 11 is used to dry the particulate material, the diverter rod 12 is used to divert the particulate material, and the transmission shaft 13 is used to connect the driver. When the transmission shaft 13 rotates, it will drive the crushing blade 14 and the synchronous transmission assembly 2 to rotate. The crushing blade 14 is used to crush larger particulate materials. When the synchronous transmission assembly 2 rotates, it will drive the vibration knocking mechanism 5 and the movable diverter screen plate 36 to operate synchronously.

[0031] The granular material is introduced into the screening box 1. First, the granular material contacts and falls on the anti-blocking screening plate 3. At the same time, the hot air mechanism 11 is started to dry the granular material to reduce the moisture in the granular material, which is helpful for the subsequent screening and crushing process. The diverter rod 12 performs preliminary diversion on the falling granular material to ensure uniform distribution of the granular material and improve the screening efficiency.

[0032] Subsequently, the particulate material continues to fall and contacts the crushing blade 14. The transmission shaft 13 is connected to the driver to rotate, driving the crushing blade 14 to rotate, and cutting and crushing the larger particulate material. However, dust will be generated in this process. Dust and particles can penetrate the anti-blocking screening plate 3. The synchronous transmission assembly 2 is connected to the transmission shaft 13. When the synchronous transmission assembly 2 rotates, it drives the vibration and percussion mechanism 5 and the movable diverter screen plate 36 to operate synchronously. The vibration and percussion mechanism 5 vibrates the material receiving guide rail 4, which helps to improve the movement efficiency of dust and small particle materials in the material receiving guide rail 4, prevents blockage, and facilitates subsequent recycling and processing. The movable diverter screen plate 36 reciprocates between the anti-blocking screening plate 3 and the material receiving bottom plate 37. This dynamic screening process effectively prevents the anti-blocking screening plate 3 from being blocked, thereby ensuring the continuity and efficiency of screening.

[0033] After passing through the anti-blocking screening plate 3, the granular material falls on the movable diverter screen plate 36. The movable diverter screen plate 36 evenly transports the granular material to the bottom outlet of the screening box 1 through reciprocating motion. In this process, due to the screening effect of the movable diverter screen plate 36, the dust is further separated, so that the dust passes through the movable diverter screen plate 36 and falls onto the material receiving bottom plate 37, and the material receiving bottom plate 37 guides the dust to the material receiving guide rail 4.

[0034] Finally, the screened granular material is transported to the processing area through the outlet at the bottom of the screening box 1, while the dust and small particles are guided to another processing area through the material receiving guide rail 4 for subsequent recovery or processing. During the entire screening process, the synergistic effect of the hot air mechanism 11, the diverter rod 12, the crushing blade 14, the vibrating knocking mechanism 5 and the movable diverter screen plate 36 achieves efficient and continuous screening of the bamboo powder biodegradable material granular material, while reducing the problems of blockage and dust pollution.

[0035] The hot air mechanism 11, the diverter rod 12, the transmission shaft 13, the crushing blade 14 and the synchronous transmission assembly 2 are all prior arts and will not be described in detail here.

[0036] See also Figures 2 to 5 As shown, the anti-blocking screening plate 3 is provided with a first inclined screening surface 31 and a first arc-shaped screening groove 32, and a plurality of screening holes 34 are provided on the first inclined screening surface 31 and the first arc-shaped screening groove 32. A plurality of dredging strips 33 are provided at the bottom of the anti-blocking screening plate 3, and sliding rails 35 are provided at both ends of the anti-blocking screening plate 3.

[0037] The sliding rail 35 of the anti-blocking screening plate 3 is used for clamping and installing the material receiving bottom plate 37, so as to facilitate the later disassembly and maintenance.

[0038] The first inclined screening surface 31 and the first arc-shaped screening slot 32 are both provided with a plurality of screening holes 34 to achieve the screening function of the particulate material.

[0039] During the screening process, the particulate material first contacts and falls on the first inclined screening surface 31. The first inclined screening surface 31 cooperates with the hot air mechanism 11 and the diverter rod 12 for preliminary screening. The hot air mechanism 11 provides a drying effect to reduce the moisture content of the material, while the diverter rod 12 ensures that the material is evenly distributed on the screening surface, thereby improving the screening efficiency. The sieve holes 34 on the first inclined screening surface 31 allow particulate materials and dust of appropriate sizes to penetrate and fall on the movable diverter screen plate 36.

[0040] Then, the material continues to fall and contacts the first arc-shaped screen slot 32. The first arc-shaped screen slot 32 is located below the crushing blade 14 and is used to cooperate with the crushing blade 14 to cut and crush larger particles. In this process, the generated dust and particulate materials can penetrate the screen hole 34 and fall on the movable diversion screen plate 36.

[0041] A plurality of dredging slats 33 are provided at the bottom of the anti-blocking screening plate 3, and the dredging slats 33 are plugged into the movable diverting screen plate 36. When the movable diverting screen plate 36 moves back and forth under the drive of the synchronous transmission assembly 2, the dredging slats 33 will dredge the movable diverting screen plate 36, ensuring that the filtering effect of the movable diverting screen plate 36 is not affected by blockage. At the same time, the reciprocating motion of the movable diverting screen plate 36 will also dredge the screen holes 34 of the anti-blocking screening plate 3, realizing a two-way dredging mechanism that effectively prevents the screen holes 34 and the movable diverting screen plate 36 from being blocked, ensuring the continuity and efficiency of screening.

[0042] See also Figures 2 to 7 As shown, the movable diverter screen plate 36 is arranged between the anti-blocking screening plate 3 and the material receiving bottom plate 37, and a second inclined screening surface 361 and a second arc-shaped screening groove 362 are provided on the movable diverter screen plate 36, and a plurality of strip screening holes 364 are provided on the second inclined screening surface 361 and the second arc-shaped screening groove 362, and anti-blocking convex strips 365 are also provided on the strip screening holes 364, and the anti-blocking convex strips 365 correspond to the screen holes 34 one by one, and a first particle discharge port 363 is provided at the bottom of the second arc-shaped screening groove 362, and the side of the movable diverter screen plate 36 also includes a reciprocating operation component 366, and the reciprocating operation component 366 is used to push the movable diverter screen plate 36 to move.

[0043] The second inclined screening surface 361 and the second arc-shaped screening slot 362 mainly function to receive the particles and dust that have passed through the anti-blocking screening plate 3. The strip-shaped screening holes 364 filter the dust and provide a falling channel for the dust, thereby achieving effective separation of the particles and the dust.

[0044] When the synchronous transmission assembly 2 is started, the reciprocating assembly 366 moves accordingly, thereby pushing the movable diversion screen plate 36 to reciprocate between the anti-blocking screening plate 3 and the material receiving bottom plate 37. During the movement, the top of the anti-blocking convex strip 365 will reciprocate with the screen hole 34 of the anti-blocking screening plate 3. The contact between the anti-blocking convex strip 365 and the screen hole 34 not only helps to push the granular material that may be stuck in the screen hole 34 to prevent the screen hole 34 from being blocked, but also further ensures that the screen hole 34 is unobstructed through continuous pushing action.

[0045] At the same time, the strip screening holes 364 on the movable diverter screen plate 36 will move along the dredging strips 33 during the reciprocating motion. The setting of the dredging strips 33 effectively prevents the strip screening holes 364 from being blocked, ensuring that dust and fine particles can smoothly pass through the strip screening holes 364, fall onto the material receiving bottom plate 37, and finally be guided to the material receiving guide rail 4.

[0046] See also Figures 3 to 10 As shown, the reciprocating operation component 366 includes a pushing and abutting column 368 installed on the side of the movable diverter screen plate 36, and a abutting ball 3681 is provided at one end of the pushing and abutting column 368 away from the movable diverter screen plate 36. A pushing driving disk 367 is provided on the side of the pushing and abutting column 368, and the abutting surface of the pushing driving disk 367 is in contact with the abutting ball 3681. A pushing plane 3671 and a pushing concave surface 3672 are provided on the abutting surface of the pushing driving disk 367. The reciprocating operation component 366 also includes a plurality of elastic pushing members 369 installed on the material receiving bottom plate 37, and the pushing ends of the elastic pushing members 369 abut against the movable diverter screen plate 36.

[0047] The push-and-contact column 368 is installed on the side of the movable diverter screen plate 36. The end of the push-and-contact column 368 away from the movable diverter screen plate 36 is provided with a contact ball 3681, and the contact ball 3681 is used for contact transmission with the push drive disk 367. The push drive disk 367 is located beside the push-and-contact column 368, and a push plane 3671 and a push concave surface 3672 are provided on the contact surface thereof. The alternating appearance of the push plane 3671 and the push concave surface 3672 provides different contact positions for the contact ball 3681, thereby driving the movable diverter screen plate 36 to reciprocate.

[0048] The elastic push piece 369 is mounted on the material receiving bottom plate 37, and the pushing end of the elastic push piece 369 contacts the movable diverter screen plate 36, and is used to always push the movable diverter screen plate 36 to move to one side. It is ensured that the contact ball 3681 on the push contact column 368 always keeps in contact with the push drive disk 367, providing a stable initial condition for the reciprocating motion.

[0049] When the synchronous transmission assembly 2 is started, the push driving disk 367 is driven to rotate. During the rotation process, the push plane 3671 and the push concave surface 3672 contact the abutting ball 3681 in sequence. Due to the drop between the push plane 3671 and the push concave surface 3672, the abutting ball 3681 is subjected to different thrusts when contacting the push plane 3671 and the push concave surface 3672, thereby pushing the push abutting column 368 to telescopically move. The telescopic movement of the push abutting column 368 further pushes the movable diversion screen plate 36 to move toward the elastic push piece 369.

[0050] See also Figures 3 to 6 As shown, the elastic pushing member 369 includes a mounting bracket 3691 mounted on the material receiving bottom plate 37, a pushing and resisting rod 3692 is slidably mounted on the mounting bracket 3691, and a first spring 3693 is installed between the pushing and resisting rod 3692 and the mounting bracket 3691.

[0051] The main function of the elastic push member 369 is to provide continuous elastic thrust for the movable diversion screen plate 36, ensuring that the resistance ball 3681 can stably maintain contact with the push drive disk 367 during the reciprocating motion of the movable diversion screen plate 36, thereby achieving effective particle screening.

[0052] The mounting bracket 3691 is firmly mounted on the material receiving bottom plate 37, providing a stable supporting platform for the pushing and resisting rod 3692. The pushing and resisting rod 3692 is slidably mounted on the mounting bracket 3691 and can perform linear motion within a certain range. The first spring 3693 is installed between the pushing and resisting rod 3692 and the mounting bracket 3691, and generates thrust through its elastic deformation.

[0053] In the working state, when the synchronous transmission assembly 2 is started and drives the pushing driving disk 367 to rotate, the pushing plane 3671 and the pushing concave surface 3672 on the pushing driving disk 367 will contact the abutting ball 3681 in sequence. Due to the height difference between the pushing plane 3671 and the pushing concave surface 3672, the abutting ball 3681 will be subjected to different thrusts when contacting the pushing plane 3671 and the pushing concave surface 3672, thereby pushing the pushing abutting column 368 to telescopically move. The telescopic movement of the pushing abutting column 368 will further push the movable diversion screen plate 36 to reciprocate.

[0054] In this process, the elastic push piece 369 always plays a key role. When the movable diverter screen plate 36 is pushed to one side by the push-and-resistance column 368, the push-and-resistance rod 3692 will also move and compress the first spring 3693. After being compressed, the first spring 3693 will generate an elastic restoring force, which will act on the push-and-resistance rod 3692, causing it to tend to move in the opposite direction. Therefore, when the push concave surface 3672 on the push drive disk 367 contacts the resistance ball 3681, the elastic restoring force of the elastic push piece 369 will push the push-and-resistance rod 3692 and the movable diverter screen plate 36 to move in the opposite direction, thereby achieving reciprocating motion.

[0055] See also Figure 5 and Figure 7 As shown, the anti-blocking convex strip 365 is in the shape of an elastic bow.

[0056] The anti-blocking convex strips 365 are designed to correspond to the strip-shaped screening holes 364 one by one and are in an elastic bow shape, so that the anti-blocking convex strips 365 can produce a certain deformation when subjected to external force, thereby adapting to different working environments and screening requirements.

[0057] When the movable diverting screen plate 36 reciprocates under the impetus of the reciprocating operating assembly 366, the top of the anti-blocking convex strip 365 will reciprocately contact the screen hole 34 of the anti-blocking screen plate 3. This contact not only helps to push the granular materials that may be stuck in the screen hole 34 to prevent the screen hole 34 from being blocked, but also further ensures that the screen hole 34 is unobstructed through continuous pushing action.

[0058] Specifically, when the granular material passes through the anti-blocking screening plate 3 and falls on the movable diversion screen plate 36, part of the granular material may be stuck in the screen hole 34, resulting in a decrease in screening efficiency. At this time, the anti-blocking convex strip 365 will continuously contact the screen hole 34 and produce a pushing action under the action of reciprocating motion. Since the anti-blocking convex strip 365 is in the shape of an elastic bow, it can produce a certain deformation when contacting the screen hole 34, thereby more effectively pushing the granular material stuck in the screen hole 34. At the same time, the reciprocating motion of the anti-blocking convex strip 365 can also continuously dredge the screen hole 34 to prevent the screen hole 34 from being blocked due to long-term use.

[0059] See also Figure 5 As shown, a second particle discharge port 371 is provided at the bottom of the material receiving bottom plate 37 , dust discharge ports 372 are symmetrically provided on both sides of the second particle discharge port 371 , and assembly blocks 373 are provided at both ends of the material receiving bottom plate 37 .

[0060] The receiving bottom plate 37 is used to support the dust that penetrates from the movable diverter screen plate 36. A second particle discharge port 371 is provided at the bottom of the receiving bottom plate 37. The second particle discharge port 371 is connected to the first particle discharge port 363 on the movable diverter screen plate 36, and together constitutes a downward passage for the particle material from the movable diverter screen plate 36 to the bottom of the screening box 1. It ensures that the screened particle material can enter the next processing stage smoothly and orderly. Dust discharge ports 372 are symmetrically provided on both sides of the second particle discharge port 371. The dust discharge port 372 guides the dust accumulated on the receiving bottom plate 37 to the receiving guide rail 4 for subsequent recovery or processing. In addition, both ends of the material receiving bottom plate 37 are provided with assembly blocks 373, which match the sliding rails 35 of the anti-blocking screening plate 3, thereby realizing the fast and stable clamping installation of the material receiving bottom plate 37 and the anti-blocking screening plate 3. This design simplifies the assembly and disassembly process of the equipment.

The vibration and knocking mechanism 5 also includes a fixed sleeve 55 installed inside the material receiving guide rail 4, the inner wall of the fixed sleeve 55 is covered with convex strips 551, the fixed sleeve 55 is sleeved on the outer side of the rotating bracket 52, and the inner wall of the resistance roller 531 is in contact with the resistance roller 531.

[0062] The rotary drive shaft 51 is rotatably mounted inside the material receiving guide rail 4 , and the rotary bracket 52 is fixedly mounted on the rotary drive shaft 51 and rotates synchronously with the rotation of the rotary drive shaft 51 .

[0063] The telescopic guide rod 53 is slidably connected to the rotating bracket 52, and a second spring 54 is installed between the two. The second spring 54 applies a pushing force to the telescopic guide rod 53, so that the abutting roller 531 at the end of the telescopic guide rod 53 always keeps close contact with the inner wall of the fixed sleeve 55. The fixed sleeve 55 is installed inside the material receiving guide rail 4, and the inner wall of the fixed sleeve 55 is covered with convex strips 551 for interacting with the abutting roller 531.

[0064] When the synchronous transmission assembly 2 drives the rotating drive shaft 51 to rotate, the rotating bracket 52 rotates synchronously therewith. The rotating motion of the rotating bracket 52 drives the telescopic guide rod 53 to rotate synchronously. During the rotation process, the abutting roller 531 rolls along the inner wall of the fixed sleeve 55. Since the inner wall of the fixed sleeve 55 is covered with convex strips 551, the abutting roller 531 is hindered by the convex strips 551 during the rolling process, thereby generating vibration.

[0065] The vibration is transmitted to the entire material receiving guide rail 4. The vibration helps to improve the moving efficiency of dust and small particles in the material receiving guide rail 4, prevents the occurrence of blockage, and facilitates the subsequent recycling process.

[0066] Specific working principle: the granular material is introduced into the screening box 1. First, the granular material contacts and falls on the anti-blocking screening plate 3. At the same time, the hot air mechanism 11 is started to dry the granular material to reduce the moisture in the granular material, which is helpful for the subsequent screening and crushing process. The diverter rod 12 performs preliminary diversion on the falling granular material to ensure that the granular material is evenly distributed and improve the screening efficiency. Subsequently, the granular material continues to fall and contacts the crushing blade 14. The transmission shaft 13 is connected to the driver to rotate, driving the crushing blade 14 to rotate, and cutting and crushing the larger granular material. However, dust is generated in this process. Dust and particles can penetrate the anti-blocking screening plate 3. The synchronous transmission component 2 is connected to the transmission shaft 13, and when the synchronous transmission component 2 rotates, it drives the vibration knocking mechanism 5 and the movable diverter screen plate 36 to operate synchronously. The vibration knocking mechanism 5 generates vibration on the receiving guide rail 4, which helps to improve the movement efficiency of dust and small granular materials in the receiving guide rail 4, prevents blockage, and facilitates subsequent recycling. The movable diversion screen plate 36 reciprocates between the anti-blocking screening plate 3 and the material receiving bottom plate 37. This dynamic screening process effectively prevents the anti-blocking screening plate 3 from being blocked, thereby ensuring the continuity and high efficiency of screening.

[0067] After passing through the anti-blocking screening plate 3, the granular material falls on the movable diverter screen plate 36. The movable diverter screen plate 36 evenly transports the granular material to the bottom outlet of the screening box 1 through reciprocating motion. In this process, due to the screening effect of the movable diverter screen plate 36, the dust is further separated, so that the dust passes through the movable diverter screen plate 36 and falls onto the material receiving bottom plate 37, and the material receiving bottom plate 37 guides the dust to the material receiving guide rail 4.

[0068] Finally, the screened granular material is transported to the processing area through the outlet at the bottom of the screening box 1, while the dust and small particles are guided to another processing area through the material receiving guide rail 4 for subsequent recovery or processing. During the entire screening process, the synergistic effect of the hot air mechanism 11, the diverter rod 12, the crushing blade 14, the vibrating knocking mechanism 5 and the movable diverter screen plate 36 achieves efficient and continuous screening of the bamboo powder biodegradable material granular material, while reducing the problems of blockage and dust pollution.

[0069] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
