Description

Wood shavings flattening device

Technical Field

The invention relates to the technical field of wood shavings flattening devices, in particular to a wood shavings flattening device.

Background technique

During the deep processing of particleboard, customers often complain about large particles on the board surface, which affects subsequent processing such as veneering, becoming a major problem in the primary and deep processing of particleboard. In addition, large particles on the board surface are also an important factor causing product degradation.

In the prior art, the shavings are evenly spread on the paving belt after passing through the paving machine. Due to gravity, fine materials or small shavings fall to the bottom of the belt, and large shavings appear on the top of the belt. However, some shavings are upright after falling down. When passing through the flattening roller, the pressure of the flattening roller is too small, and the large shavings are not enough to press down. The pressure is too large, causing indentations on the slab, affecting the local density and other properties. Therefore, after the shavings pass through the flattening roller, they follow the paving belt into the hot pressing section and are pressed into finished products. When the finished board is sanded, the shavings that have not been flattened appear on the surface of the board, which has a great impact on the quality of the plain board, increases the difficulty of subsequent deep processing, causes a low rate of high-quality products, and wastes production costs. For this reason, we propose a shavings flattening device.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1-5. The present invention provides a technical solution: a wood shavings flattening device, including a frame 1, a slide plate 2, a slider 3, a support platform 4, a spring 5, a locking pin 6, a locking socket 7, a rack 8, a gear 9, a transverse connecting rod 10, a rotating motor 11, a leveling roller drive reduction mechanism 12, a leveling roller 13, a paving belt 14, a passive roller 15, a flattening roller drive reduction mechanism 16, a flattening belt 17, a driving roller 18, a side fixing plate 19, a telescopic rod 20, a first bolt 21, a right-angle connecting frame 22, a pressure roller linear guide 23, and a second bolt 24. Side baffle 25. A slide plate 2 is attached to one side of the outer wall of the frame 1, and a slider 3 is attached to the inner wall of the slide plate 2. The slide plate 2 and the frame 1 are welded to each other, and a sliding structure is formed between the slide plate 2 and the slider 3. The slide plate 2 is fixed by the frame 1 to ensure that the device can move stably in the vertical direction, and the inside of the slide plate 2 is a trapezoidal structure, which is consistent with the outer wall structure of the slider 3. The advantage of this is that it ensures that the leveling roller 13 will not shake left and right during the up and down movement or rotation operation, thereby improving the overall stability of the device;

The locking pin 6 is pressed against the locking hole 7 by the spring 5 when the user moves the leveling roller 13 upward or downward, and the locking pin 6 is squeezed from the upper and lower sides of the locking hole 7, thereby triggering the spring 5 to have a lateral elastic contraction, and finally the locking pin 6 will leave the locking hole 7 and continue to move along the outer wall of the frame 1. When the locking pin 6 encounters the next locking hole 7, the spring 5 will immediately perform a reset movement, thereby prompting the locking pin 6 to enter the locking hole 7. The locking pin 6 is in a "T"-shaped structure as a whole, so the spring 5 will not completely pop out the locking pin 6.

A rack 8 is attached to one side of the outer wall of the slide rail plate 2, and a gear 9 is meshed with the outer wall of the rack 8. The rack 8 and the slide rail plate 2 are welded into an integrated structure, and the overall length of the rack 8 is the same as the length of the slide rail plate 2;

A transverse connecting rod 10 runs through the middle of the inner wall of the gear 9, the rack 8 and the gear 9 are meshed with each other, and the rack 8 and the gear 9 are symmetrically distributed along the outer wall of the transverse connecting rod 10. The rack 8 and the slide plate 2 are at the same length to ensure that the slider 3 and the gear 9 are kept on the same horizontal line at any position, to ensure that the leveling roller 13 is in a relatively stable motion state when moving up and down, to prevent the speed from hitting the frame 1 or the bottom of the paving belt 14 too fast, causing damage to the device, and the relative movement between the rack 8 and the gear 9 and the slider 3 and the slide plate 2 is to enable the leveling roller 13 to be adjusted to different heights according to the thickness of the slab;

A rotating motor 11 is installed on one side of the outer wall of the support platform 4, and a leveling roller driving reduction mechanism 12 is connected to the other side of the outer wall of the support platform 4, a leveling roller 13 is connected to the end of the leveling roller driving reduction mechanism 12, and a paving belt 14 is distributed in parallel at the lower end of the outer wall of the leveling roller 13, the rotating motor 11 forms a transmission structure with the leveling roller 13 through the leveling roller driving reduction mechanism 12, and the leveling roller 13 and the transverse connecting rod 10 are parallel to each other;

A passive roller 15 is distributed parallel to one side of the outer wall of the leveling roller 13, and one end of the outer wall of the passive roller 15 is connected to a flattening roller driving reduction mechanism 16, a flattening belt 17 is attached to the outer wall of the passive roller 15, and a driving roller 18 is attached to one side of the inner wall of the flattening belt 17, the passive roller 15 is tangent to the inner wall of the flattening belt 17, and the flattening roller driving reduction mechanism 16 forms a transmission structure through the passive roller 15 and the flattening belt 17 and the driving roller 18, and the leveling roller driving reduction mechanism 12 mainly connects and transmits the kinetic energy generated by the rotating motor 11, and drives the leveling roller 13 to move. The leveling roller driving speed reduction mechanism 12 mainly adopts a chain for transmission. At the same time, the diameter of the rotating motor 11 and the leveling roller driving speed reduction mechanism 12 is larger than the diameter of the leveling roller 13 and the leveling roller driving speed reduction mechanism 12. This can achieve a deceleration effect to prevent the machine from working unstably due to the excessive speed of the rotating motor 11. The outer wall of the leveling roller 13 is a serrated structure. The leveling roller 13 needs to first level and break up the unevenly stacked slabs to prevent the accumulated slabs from entering the flattening device and damaging the flattening belt 17 and the paving belt 14.

The passive roller 15 is tangent to the inner wall of the flattening belt 17, and the flattening roller driving reduction mechanism 16 forms a transmission structure between the passive roller 15, the flattening belt 17 and the driving roller 18. The rotating motor 11 drives the passive roller 15 to rotate through the flattening roller driving reduction mechanism 16, and the passive roller 15 drives the driving roller 18 to move through the flattening belt 17. When the slab enters the flattening device, the flattened slab contacts the passive roller 15 for preliminary flattening, and then the flattening belt 17 and the passive roller 15 flatten the shavings on the surface of the slab, thereby solving the problem of large shavings on the board surface.

Side fixing plates 19 are installed on both sides of the outer wall of the driving roller 18, and a telescopic rod 20 is connected to one side of the outer wall of the side fixing plate 19. The side fixing plates 19 are respectively installed on both sides of the outer wall of the driving roller 18 and the passive roller 15, and the side fixing plates 19 are symmetrically distributed along both sides of the vertical center line of the telescopic rod 20;

The inner wall of the side fixing plate 19 is fitted with a first bolt 21, and the end of the first bolt 21 is connected to a right-angle connecting frame 22. The first bolt 21 penetrates through one side of the outer wall of the side fixing plate 19 and the right-angle connecting frame 22 respectively, and the transverse cross-section of the penetration point of the first bolt 21 on one side of the outer wall of the right-angle connecting frame 22 presents a strip-shaped structure. During the flattening process, the user can adjust the tightness of the flattening belt 17 by adjusting the first bolt 21 to avoid affecting the paving effect of the slab by being too tight or too loose;

The roller linear guide rails 23 are attached to both sides of the outer wall of the right-angle connecting frame 22, and the second bolts 24 are penetrated on both sides of the outer wall of the roller linear guide rail 23. The second bolts 24 penetrate the right-angle connecting frame 22 and one side of the outer wall of the roller linear guide rail 23 respectively, and the roller linear guide rail 23 and the frame 1 are welded into an integrated structure. The second bolts 24 mainly play a role in adjusting the height of the right-angle connecting frame 22 on the roller linear guide rail 23. At the same time, the side fixing plate 19 is connected to the right-angle connecting frame 22 through the second bolts 24, so that the position of the driving roller 18 and the passive roller 15 in the vertical direction can be adjusted;

Side baffles 25 are installed on both sides of the outer wall of the paving belt 14. The side baffles 25 are symmetrically distributed along both sides of the outer wall of the paving belt 14, and the side baffles 25 and the paving belt 14 are perpendicular to each other. The side baffles 25 limit the width of the slab. After flattening, the slab is transported to the next processing section along the paving belt 14.

Working principle: For this type of shavings flattening device, first, the slide plate 2 is fixed with the frame 1 to ensure that the device can move stably in the vertical direction, and the interior of the slide plate 2 is a trapezoidal structure, which is consistent with the outer wall structure of the slider 3. The advantage of this is that it ensures that the leveling roller 13 will not shake left and right during the up and down movement or rotation operation, thereby improving the overall stability of the device. A spring 5 and a locking pin 6 are installed inside the support table 4. When the user moves the leveling roller 13 up or down, the locking pin 6 will be squeezed from the upper and lower sides of the locking hole 7, thereby triggering the spring 5 to have a lateral elastic contraction, and finally the locking pin 6 will leave the locking hole 7 and continue to move along the outer wall of the frame 1. When the locking pin 6 encounters the next locking hole 7, The spring 5 will immediately perform a reset movement, thereby prompting the locking pin 6 to enter the interior of the locking socket 7. The locking pin 6 is in a "T"-shaped structure as a whole, so the spring 5 will not completely pop out the locking pin 6. The rack 8 and the slide plate 2 are of the same length to ensure that the slider 3 and the gear 9 are kept on the same horizontal line at any position, ensuring that the leveling roller 13 is in a relatively stable movement state during the up and down movement to prevent the speed from hitting the frame 1 or the bottom of the paving belt 14 too fast, causing damage to the device. The relative movement between the rack 8 and the gear 9 and the slider 3 and the slide plate 2 is to enable the leveling roller 13 to be adjusted to different heights according to the thickness of the slab. The leveling roller drive reduction mechanism 12 mainly connects and transmits the kinetic energy generated by the rotating motor 11 to drive the leveling roller 13. The flat roller 13 is used to rotate, and the flat roller drive reduction mechanism 12 is mainly driven by a chain. At the same time, the diameters of the rotating motor 11 and the flat roller drive reduction mechanism 12 are larger than the diameters of the flat roller 13 and the flat roller drive reduction mechanism 12. This can achieve a deceleration effect to prevent the machine from working unstably due to the excessive speed of the rotating motor 11. The outer wall of the flat roller 13 is a serrated structure. The flat roller 13 needs to first sweep and break up the unevenly stacked slabs to prevent the accumulated slabs from entering the flattening device and damaging the flattening belt 17 and the paving belt 14. The rotating motor 11 drives the passive roller 15 to rotate through the flattening roller drive reduction mechanism 16. The passive roller 15 drives the driving roller 18 to move through the flattening belt 17. When the slab enters the flattening device The broken and flattened slab contacts the passive roller 15 for preliminary flattening, and then the flattening belt 17 and the passive roller 15 flatten the shavings on the surface of the slab. During the flattening process, the user can adjust the tightness of the flattening belt 17 by adjusting the first bolt 21 to avoid affecting the paving effect of the slab by being too tight or too loose. The second bolt 24 mainly plays a role in adjusting the height of the right-angle connecting frame 22 on the roller linear guide 23. At the same time, the side fixing plate 19 is connected to the right-angle connecting frame 22 through the second bolt 24. In this way, the position of the driving roller 18 and the passive roller 15 in the vertical direction can be adjusted. The side baffle 25 limits the width of the slab. After flattening, the slab is transported to the next processing section along with the paving belt 14, thus completing the use process of the entire shavings flattening device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
