Description

Technical Field

[0001] This utility model relates to the field of particleboard processing technology, specifically to a particleboard screening machine for particleboard processing. Background Technology

[0002] In the particleboard processing, particle size classification of wood chips is one of the key steps in determining the quality of the board. Therefore, it is necessary to use a screening machine to accurately separate the wood chips into coarse and fine materials according to their particle size, so as to meet the laying requirements of the core layer, transition layer and surface layer respectively, in order to ensure the structural stability and performance of the final product. Among them, the linear vibrating screen is widely used in small and medium-sized to large-scale particleboard production lines due to its compact structure, convenient operation and high screening efficiency. Its working principle is mainly to drive the screen bucket to perform linear reciprocating vibration through the vibrator, so that the wood chips on the screen plate move under the action of inertial force and gravity. Wood chips with a particle size smaller than the screen hole pass through the screen and are classified, while larger wood chips are conveyed along the surface of the screen plate to the left side of the front end of the screen bucket for discharge.

[0003] However, existing linear vibrating screens still have significant shortcomings in processing wood shavings. Since wood shavings are mostly flaky structures with a certain degree of looseness, their movement within the screen hopper mainly depends on the overall vibration of the hopper. In the actual screening process, the upper layer of wood shavings tends to have poor mobility due to its loose accumulation and cushioning, making it difficult for them to be fully agitated by the screen plate. This results in the inability to effectively remove these wood shavings, thus affecting the screening effect. At the same time, the edges of the flaky wood shavings are easily stuck in the screen holes. In addition, the continuous compression of the screen holes by the wood shavings during vibration can easily cause screen blockage. This not only requires frequent shutdowns for cleaning but also reduces screening efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a shavings screening machine for particleboard processing. This machine enhances the movement of shavings, significantly reduces screen hole clogging, and improves screening efficiency and quality. It improves or solves, to a certain extent, the significant shortcomings of existing linear vibrating screens in processing shavings. Since shavings are mostly flake-like structures with a certain degree of looseness, their movement within the screen hopper mainly relies on the overall vibration of the hopper. In actual screening, the upper layer of shavings tends to have poor movement due to its loose accumulation and buffering effect, making it difficult to be fully agitated by the screen plate. This results in the ineffective screening of these shavings, thus affecting the screening effect. Furthermore, the edges of the flake-like shavings easily get stuck in the screen holes. Combined with the continuous compression of the screen holes by the shavings during vibration, this easily causes screen hole clogging, requiring frequent shutdowns for cleaning and reducing screening efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a particleboard screening machine, comprising a frame, springs, a screen bucket, a screen plate, screen holes, and a vibrator.

[0006] An anti-clogging device is provided below the sieve plate, and a turning component is provided above the sieve plate. There are three turning components, which are evenly arranged inside the upper part of the sieve hopper.

[0007] As a preferred embodiment of the present invention, the anti-blocking device includes a striking component and a linkage control component. The number of striking components is five, and they are evenly arranged at the lower end of the sieve plate. The linkage control component is located on the lower right side of the five striking components.

[0008] In a preferred embodiment of this invention, the striking assembly includes a rotating seat, a striking plate, and tension springs. The rotating seat is fixedly connected to the right side of the lower surface of the sieve plate. The right end of the striking plate is sleeved on the surface of the rotating seat and rotatably connected to the rotating seat. There are three tension springs, all of which are fixedly connected to the left end of the upper surface of the striking plate, and their upper ends are fixedly connected to the left side of the lower surface of the sieve plate.

[0009] As a preferred embodiment of this invention, a plurality of rubber protrusions are uniformly fixedly connected to the upper surface of the clapper plate, and the upper sides of the plurality of rubber protrusions are in contact with the lower surface of the sieve plate.

[0010] In a preferred embodiment of this invention, the linkage control assembly includes a rotating rod, a motor, support seats, extrusion wheels, and a transmission wheel. The rotating rod is positioned below the right end of the five clappers, with its rear end extending out of the sieve bucket and rotatably connected to it. The motor is fixedly connected to the rear end of the rotating rod and to the rear end of the sieve bucket. Several support seats are evenly fitted onto the surface of the rotating rod and rotatably connected to it. The upper ends of each support seat are fixedly connected to the upper surface of the sieve plate. Five extrusion wheels are evenly fitted onto the surface of the rotating rod and fixedly connected to it. The five extrusion wheels correspond to and are adapted to the right ends of the five clappers. The transmission wheel is fitted onto the rear end surface of the rotating rod and fixedly connected to it.

[0011] In a preferred embodiment of this utility model, the flipping assembly includes a flipping shaft, a fixed sleeve, rubber flaps, and a second transmission wheel. The flipping shaft is disposed on the upper end of the sieve bucket, and both its front and rear ends are rotatably connected to the sieve bucket, with its rear end extending out of the sieve bucket. The fixed sleeve is sleeved on the surface of the flipping shaft and is fixedly connected to the flipping shaft. The number of rubber flaps is several, and they are evenly fixedly connected to the circumference of the fixed sleeve. The second transmission wheel is fixedly connected to the rear end of the flipping shaft.

[0012] The three drive wheels are interconnected by two drive belts, and the drive wheel on the right side is connected to the drive wheel at the rear end of the rotating rod by a drive belt.

[0013] As a preferred embodiment of this utility model, the surfaces of the three transmission wheels 2 and 1 are fitted with protective shells, which are fixedly connected to the rear surface of the screen bucket and rotatably connected to the rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the coordinated use of a frame, spring, screen bucket, screen plate, screen holes, vibrator, anti-blocking device, striking assembly, rotating seat, striking plate, tension spring, linkage control assembly, rotating rod, motor, support seat, extrusion wheel, transmission wheel one, flipping assembly, flipping shaft, fixing sleeve, rubber flipping plate, transmission wheel two, rubber protrusion, transmission belt, and protective shell, improves or solves to a certain extent the significant shortcomings of existing linear vibrating screens in processing wood shavings. Since wood shavings are mostly flake-shaped structures with a certain degree of looseness, their movement in the screen bucket mainly depends on the overall vibration of the screen bucket. In the actual screening process, the upper layer of wood shavings is prone to poor mobility due to the loose accumulation and buffer, making it difficult to be fully agitated by the screen plate. This results in the inability to effectively screen out this part of the wood shavings, thus affecting the screening effect. At the same time, the edges of the flake-shaped wood shavings are easy to get stuck in the screen holes. In addition, the continuous extrusion of the screen holes by the wood shavings during vibration can easily cause screen hole blockage, which not only requires frequent shutdowns for cleaning but also reduces screening efficiency.

[0016] 2. This utility model, by setting an anti-clogging device, wherein the striking component and the linkage control component cooperate to use the rubber protrusions to strike the screen plate, can not only reduce the clogging of the screen holes by wood shavings, but also enhance the vibration intensity of the screen plate to improve the movement of wood shavings and reduce the frequency of downtime for cleaning.

[0017] 3. By setting three flipping components, this utility model can fully flip the wood shavings in different areas above the sieve plate, breaking their loose and piled state, so that the upper layer of wood shavings can also move fully, greatly improving the uniformity and thoroughness of screening.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0028] Example 1

[0029] Reference Figure 1-5 The first embodiment of this utility model provides a particleboard screening machine, including a frame 1, springs 2, a sieve bucket 3, a sieve plate 4, sieve holes 5, and a vibrator 6. There are four springs 2, which are fixedly connected to the four corners of the upper end of the frame 1. The sieve bucket 3 is fixedly connected to the upper ends of the four springs 2. The sieve plate 4 is located in the middle of the sieve bucket 3 and is fixedly connected to the sieve bucket 3. There are several sieve holes 5, which are evenly opened on the surface of the sieve plate 4. There are two vibrators 6, which are fixedly connected to the left and right sides of the sieve bucket 3.

[0030] An anti-blocking device 7 is provided below the sieve plate 4, and a turning component 8 is provided above the sieve plate 4. There are three turning components 8, which are evenly arranged inside the upper part of the sieve hopper 3.

[0031] Specifically, the wood shavings screening machine effectively improves the mobility of wood shavings in the sieve hopper 3 and reduces clogging of the sieve holes 5 through the synergistic effect of the anti-clogging device 7 and the turning component 8, thus significantly improving the efficiency and quality of wood shavings screening.

[0032] Furthermore, during operation, the vibrator 6 drives the screen bucket 3 to reciprocate linearly under the support of the spring 2, causing the wood shavings on the screen plate 4 to move along the screen surface. In the anti-clogging device 7, the motor 722 drives the rotating rod 721 to rotate, and the extrusion wheel 724 alternately extrudes the clapping plate 712. With the help of the tension spring 713, the clapping plate 712 strikes the screen plate 4 through the rubber protrusion 9 to prevent clogging. At the same time, the rotating rod 721 drives the second transmission wheel 84 of the flipping assembly 8 to rotate through the first transmission wheel 725, causing the rubber flipping plate 83 on the flipping shaft 81 to rotate and flip the upper layer of wood shavings, ensuring that they are in full contact with the screen plate 4 and achieving efficient screening.

[0033] Example 2

[0034] In the second embodiment of this utility model, the anti-blocking device 7 includes a striking component 71 and a linkage control component 72. The number of striking components 71 is five, and they are evenly arranged at the lower end of the sieve plate 4. The linkage control component 72 is arranged on the lower right side of the five striking components 71.

[0035] The striking assembly 71 includes a rotating seat 711, a striking plate 712, and a tension spring 713. The rotating seat 711 is fixedly connected to the right side of the lower surface of the sieve plate 4. The right end of the striking plate 712 is sleeved on the surface of the rotating seat 711 and is rotatably connected to the rotating seat 711. There are three tension springs 713, all of which are fixedly connected to the left end of the upper surface of the striking plate 712, and their upper ends are fixedly connected to the left side of the lower surface of the sieve plate 4.

[0036] Several rubber protrusions 9 are evenly fixedly connected to the upper surface of the clapper plate 712, and the upper side of the rubber protrusions 9 is in contact with the lower surface of the sieve plate 4.

[0037] Specifically, by setting up an anti-clogging device 7, in which the striking component 71 and the linkage control component 72 work together, the rubber protrusions 9 strike the screen plate 4, which can reduce the clogging of the screen holes 5 by wood shavings and enhance the vibration intensity of the screen plate 4 to improve the activity of wood shavings and reduce the frequency of downtime for cleaning.

[0038] Furthermore, the motor 722 starts and drives the rotating rod 721 to rotate. The five extrusion rollers 724 on the rotating rod 721 rotate synchronously. When the extrusion rollers 724 rotate to contact the right end of the clapper plate 712, they will squeeze the clapper plate 712, causing the clapper plate 712 to flip downward around the rotating seat 711 and stretch the tension spring 713. When the extrusion rollers 724 separate from the right end of the clapper plate 712, the reset tension of the tension spring 713 will cause the clapper plate 712 to flip upward quickly. The rubber protrusions 9 on the upper surface of the clapper plate 712 will strike the lower surface of the sieve plate 4. This striking action causes the sieve plate 4 to vibrate instantaneously, which can effectively shake off the flaky wood chips stuck in the sieve holes 5, avoid clogging of the sieve holes 5, and also adjust the mobility of the wood chips on the sieve plate 4.

[0039] Example 3

[0040] In the third embodiment of this utility model, the linkage control component 72 includes a rotating rod 721, a motor 722, a support base 723, an extrusion wheel 724, and a transmission wheel 725. The rotating rod 721 is located on the lower right side of the five clappers 712, and its rear end extends out of the sieve hopper 3 and is rotatably connected to the sieve hopper 3. The motor 722 is fixedly connected to the rear end of the rotating rod 721 and is also fixedly connected to the rear end of the sieve hopper 3. There are several support bases 723, which are evenly fitted on the surface of the rotating rod 721 and are rotatably connected to the rotating rod 721. The upper ends of the several support bases 723 are all fixedly connected to the upper surface of the sieve plate 4. There are five extrusion wheels 724, which are evenly fitted on the surface of the rotating rod 721 and are fixedly connected to the rotating rod 721. The five extrusion wheels 724 correspond to and are adapted to the right ends of the five clappers 712. The transmission wheel 725 is fitted on the rear end surface of the rotating rod 721 and is fixedly connected to the rotating rod 721.

[0041] The flipping assembly 8 includes a flipping shaft 81, a fixed sleeve 82, rubber flaps 83, and a second transmission wheel 84. The flipping shaft 81 is located at the upper end of the sieve hopper 3, and both its front and rear ends are rotatably connected to the sieve hopper 3, with its rear end extending out of the sieve hopper 3. The fixed sleeve 82 is fitted onto the surface of the flipping shaft 81 and is fixedly connected to the flipping shaft 81. There are several rubber flaps 83, which are evenly fixedly connected to the circumference of the fixed sleeve 82. The second transmission wheel 84 is fixedly connected to the rear end of the flipping shaft 81.

[0042] The three drive wheels 84 are interconnected by two drive belts 10. The drive wheel 84 on the right side is connected to the drive wheel 725 at the rear end of the rotating rod 721 by the drive belt 10.

[0043] The surfaces of the three drive wheels 84 and 725 are fitted with protective shells 11. The protective shells 11 are fixedly connected to the rear surface of the screen bucket 3 and rotatably connected to the rotating rod 721.

[0044] Specifically, by setting three turning components 8, the wood shavings in different areas above the sieve plate 4 can be fully turned over, breaking their loose and piled state, so that the upper layer of wood shavings can also move fully, greatly improving the uniformity and thoroughness of screening.

[0045] Furthermore, when the rotating rod 721 rotates, the first transmission wheel 725 at the rear end drives the second transmission wheel 84 of the right-side flipping assembly 8 to rotate via the transmission belt 10. The second transmission wheel 84 on the right side then drives the other two transmission wheels 84 to rotate via the transmission belt 10, thereby causing the three flipping shafts 81 to rotate. The fixed sleeve 82 and the rubber flap 83 on the flipping shaft 81 rotate together with the flipping shaft 81. During the rotation, the rubber flap 83 flips the wood shavings above the sieve plate 4. This process can break the loose accumulation of wood shavings, allowing the wood shavings that were originally on the upper layer to move downwards and fully contact the sieve plate 4, ensuring that the wood shavings that meet the size of the sieve hole 5 can pass through the sieve hole 5 smoothly and complete the screening.

[0046] Working principle:

[0047] When in use, the vibrator 6 is started and the vibrator 6 drives the screen bucket 3. The screen bucket 3 vibrates linearly under the elastic support of the four springs 2. At this time, the wood shavings to be screened are poured into the screen bucket 3 and move forward along the surface of the screen plate 4 under the vibration of the screen bucket 3.

[0048] Simultaneously, the motor 722 starts and drives the rotating rod 721 to rotate. The five extrusion rollers 724 on the rotating rod 721 rotate synchronously. When the extrusion rollers 724 rotate to contact the right end of the clapper plate 712, they will squeeze the clapper plate 712, causing the clapper plate 712 to flip downward around the rotating seat 711 and stretch the tension spring 713. When the extrusion rollers 724 separate from the right end of the clapper plate 712, the reset tension of the tension spring 713 will cause the clapper plate 712 to flip upward quickly. The rubber protrusions 9 on the upper surface of the clapper plate 712 will strike the lower surface of the sieve plate 4. This striking action causes the sieve plate 4 to vibrate instantaneously, which can effectively shake off the flaky shavings stuck in the sieve holes 5, avoid clogging the sieve holes 5, and also adjust the mobility of the shavings on the sieve plate 4.

[0049] When the rotating rod 721 rotates, the first transmission wheel 725 at the rear end drives the second transmission wheel 84 of the right-side flipping assembly 8 to rotate through the transmission belt 10. The second transmission wheel 84 on the right side then drives the other two transmission wheels 84 to rotate through the transmission belt 10, thereby causing the three flipping shafts 81 to rotate. The fixed sleeve 82 and the rubber flap 83 on the flipping shaft 81 rotate together with the flipping shaft 81. During the rotation, the rubber flap 83 flips the wood shavings above the sieve plate 4. This process can break the loose accumulation of wood shavings, allowing the wood shavings that were originally on the upper layer to move downwards and fully contact the sieve plate 4, ensuring that the wood shavings that meet the size of the sieve hole 5 can pass through the sieve hole 5 smoothly and complete the screening. The larger wood shavings that do not pass through continue to move along the sieve plate 4 to the left side of the front end of the sieve hopper 3 and are discharged.

[0050] In summary, by using the combined components of frame 1, spring 2, sieve bucket 3, sieve plate 4, sieve holes 5, vibrator 6, anti-clogging device 7, striking assembly 71, rotating seat 711, striking plate 712, tension spring 713, linkage control assembly 72, rotating rod 721, motor 722, support seat 723, extrusion wheel 724, transmission wheel one 725, flipping assembly 8, flipping shaft 81, fixing sleeve 82, rubber flipping plate 83, transmission wheel two 84, rubber protrusion 9, transmission belt 10, and protective shell 11, the effects of enhanced wood shaving activity, significantly reduced sieve hole clogging, and improved screening efficiency and quality are achieved.
