Description

Technical Field

[0001] The invention belongs to the technical field of deburring wooden furniture, in particular to an edge burr processing device for manufacturing wooden furniture. Background Art

[0002] In the modern furniture manufacturing industry, wood board is one of the most common raw materials in the production process of wooden furniture. For wooden furniture such as cabinets, boxes and tables, it is often necessary to remove the burrs on the surface and edges before assembly. At present, the common way is to convey the board to move by a conveyor belt, and set a pressure roller for pressing the board down above the conveyor belt to achieve the downward pressure of the board, and then set a motor above the board to drive a row of flower heads to rotate to achieve the removal of burrs on the board. At the same time, the operator will also drive the reciprocating movement of the motor and the flower head by setting a reciprocating component to improve the effect of the flower head on removing burrs on the board. However, for processing boards of different thicknesses, since the distance between the brush body on the flower head and the upper surface of the conveyor belt is fixed, when the flower head removes burrs on thicker boards, the degree of extrusion and deformation of the brush body on the flower head will increase, which will cause the surface of the board to be subjected to greater pressure. At this time, the brush body on the flower head may cause the surface of the board to be scratched. Therefore, in order to solve the above problems, an edge burr processing device for wooden furniture manufacturing is proposed. Summary of the invention

[0011] Preferably, the adjustment mechanism further comprises an elastic limiting component fixed to the pressure roller at equal distances;

[0012] The elastic limiting assembly is used to keep the plate conveyed on the conveyor belt mechanism pressed downward.

[0013] Preferably, the elastic limiting assembly comprises a cover body 1 and a cover body 2, both of which have diameters smaller than the diameter of the middle part of the pressure roller, and the two cooperate to form a circular plate cover;

[0014] The inner circumference array of the circular plate cover is elastically connected with an elastic rod, and one end of the elastic rod away from the center of the circle extends to the outside of the circular plate cover.

[0015] Preferably, the rod body portion of the elastic rod is arc-shaped.

[0016] Preferably, the bracket is also provided with a cleaning component for intermittently cleaning the flower head.

[0017] Preferably, the cleaning assembly comprises a fixed pipe fixedly connected between the two brackets, a sleeve sleeved on the outside of the fixed pipe is fixedly connected to the bottom of the frame at equal distances, a hose is fixedly connected to the middle of the sleeve, one end of the fixed pipe is connected to the air pump, and the other end is sealed;

[0018] The fixed pipe is provided with straight slots at equal intervals, and the fixed pipe can be connected with the hose through the straight slots;

[0024] The above scheme places the plate on the conveyor belt mechanism for transportation and passes under the pressure roller. At this time, the plate will squeeze the pressure roller upward and drive the ladder frame and the frame body, the connecting shaft and the flower head upward. Therefore, when the thickness of the plate becomes thicker, it is ensured that the flower head brush body will not scratch the surface of the plate when removing burrs on the surface and edge of the plate. At the same time, the bracket supports the driving mechanism as a whole, avoiding the weight of the driving mechanism from being transferred to the flower head, and further avoiding the situation that the flower head brush body scratches the surface of the plate.

[0025] The above scheme uses the conveyor belt mechanism to transport the plate, so that the elastic rod will first contact the top of the plate, and the plate will also cause the elastic rod to retract into the cover body 1 and the cover body 2 when moving. At the same time, the ends of the multiple elastic rods squeeze the plate to make the plate more stable during transportation, and the parts that are not in contact with the top of the plate will be on both sides of the plate, thereby stabilizing the two sides of the plate during transportation and ensuring the stability of the flower head when removing burrs from the plate;

[0026] The above scheme drives the sleeve to reciprocate outside the fixed pipe by the reciprocating movement of the frame body 1, so that the fixed pipe and the straight slot are intermittently connected to the hose. Since the air pump continuously injects gas into the fixed pipe, the gas will sequentially and intermittently enter the cavity through the hose, the frame body 2 and the through hole, and finally be discharged from the bottom of the cavity to clean the wood chips remaining between the brush bodies on the flower head.

DETAILED DESCRIPTION

[0038] 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.

[0039] like Figures 1 to 10 As shown, the present invention provides an edge burr processing device for wooden furniture manufacturing, comprising a support 1, a conveyor belt mechanism 11 and a bracket 12, wherein the conveyor belt mechanism 11 is arranged on the support 1, and the bracket 12 is symmetrically arranged on the edge of the support 1, and further comprising: an adjustment mechanism 2, which is arranged at the bottom of the bracket 12; a deburring mechanism 4, which is movably installed on the adjustment mechanism 2; a driving mechanism 3, which is arranged at the top of the bracket 12 and is used to drive the deburring mechanism 4;

[0040] The adjustment mechanism 2 includes a spring limiting rod 21 fixedly connected to the bottom of the bracket 12, and a ladder frame 22 is sleeved on the outside of the spring limiting rod 21. The ladder frame 22 is subjected to the downward elastic force of the spring on the spring limiting rod 21, and a pressure roller 23 is symmetrically and movably connected to the ladder frame 22;

[0041] The deburring mechanism 4 includes a second frame body 41 movably connected to the top of the ladder frame 22, and a connecting shaft 42 is movably installed in the second frame body 41 at a horizontal distance. A flower head 43 located between two pressure rollers 23 is fixedly connected to the bottom of the connecting shaft 42, and a spline shaft 44 is movably sleeved on the top of the flower head 43;

[0042] The minimum distance between the bottom of the flower head 43 and the conveyor belt mechanism 11 is smaller than the minimum distance between the pressure roller 23 and the conveyor belt mechanism 11;

[0043] The driving mechanism 3 includes a frame body 31 movably connected to the top of the bracket 12, a driving motor 32 is fixedly connected to the top of the frame body 31 at an equal distance, and the output shaft end of the driving motor 32 is fixedly connected to the top of the spline shaft 44;

[0044] The driving mechanism 3 also includes a crank-connecting rod motor assembly 33 fixedly mounted on the top of the frame 1 31, and one end of the connecting rod on the crank-connecting rod motor assembly 33 is hinged to the bracket 12;

[0045] The crank connecting rod motor assembly 33 is used to drive the frame 1 31 to reciprocate in the horizontal direction;

[0046] By adopting the above scheme, the plate is placed on the conveyor belt mechanism 11 for transportation and passes under the pressure roller 23. At this time, the plate will squeeze the pressure roller 23 upward and drive the ladder frame 22 and the frame body 2 41, the connecting shaft 42 and the flower head 43 upward, so that when the thickness of the plate becomes thicker, it can be ensured that the brush body of the flower head 43 will not scratch the surface of the plate when removing burrs on the surface and edge of the plate. At the same time, the bracket 12 supports the driving mechanism 3 as a whole, avoiding the weight of the driving mechanism 3 from being transferred to the flower head 43, and further avoiding the situation where the brush body of the flower head 43 will scratch the surface of the plate.

[0047] like Figure 1-4 , Figure 7 and Fig. 9 As shown, the adjustment mechanism 2 also includes an elastic limiting assembly 24 fixedly connected to the pressure roller 23 at equal distances; the elastic limiting assembly 24 is used to keep the plate conveyed on the conveyor belt mechanism 11 pressed down;

[0048] The elastic limiting assembly 24 includes a cover body 1 241 and a cover body 242, both of which have diameters smaller than the diameter of the middle portion of the pressing roller 23, and the two cooperate to form a circular plate cover;

[0049] The circular plate cover is elastically connected to an elastic rod 243 in an array on the inner circumference thereof, and one end of the elastic rod 243 away from the center of the circle extends to the outside of the circular plate cover;

[0050] The rod body portion of the elastic rod 243 is arc-shaped;

[0051] By adopting the above scheme, the plate is conveyed and moved by the conveyor belt mechanism 11, so that the elastic rod 243 will first contact the top of the plate, and the plate will also cause the elastic rod 243 to retract into the cover body 1 241 and the cover body 2 242 when the plate moves. At the same time, the ends of the multiple elastic rods 243 squeeze the plate to make the plate more stable during transportation, and the parts that are not in contact with the top of the plate will be on both sides of the plate, thereby stabilizing the two sides of the plate during transportation and ensuring the stability of the flower head 43 when removing burrs from the plate.

[0052] At the same time, the body of the elastic rod 243 is designed to be arc-shaped, which avoids the situation where the body of the elastic rod 243 abuts against the top of the plate and cannot rotate when the elastic limiting assembly 24 as a whole rotates with the pressure roller 23.

[0053] like Figure 1-2 , Figure 5 , Figure 7-8 and Fig.10 As shown, the bracket 12 is also provided with a cleaning assembly 5 for intermittently cleaning the flower head 43;

[0054] The cleaning assembly 5 includes a fixed pipe 51 fixedly connected between the two brackets 12, a sleeve 52 sleeved on the outside of the fixed pipe 51 is fixedly connected to the bottom of the frame 1 31 at equal distances, a hose 53 is fixedly connected to the middle of the sleeve 52, one end of the fixed pipe 51 is connected to the air pump, and the other end is sealed;

[0055] The fixed pipe 51 is provided with straight slots 511 at equal intervals, and the fixed pipe 51 can be connected to the hose 53 through the straight slots 511;

[0056] The bottom end of the hose 53 is fixedly connected to the inner cavity of the frame 2 41;

[0057] The connecting shaft 42 is also provided with a through hole 421, the flower head 43 is also provided with a cavity 431, and the frame body 41 is connected with the cavity 431 through the through hole 421;

[0058] By adopting the above scheme, the reciprocating movement of the frame 1 31 drives the sleeve 52 to reciprocate outside the fixed pipe 51, so that the fixed pipe 51 and the straight slot 511 are intermittently connected with the hose 53. Since the air pump continuously injects gas into the fixed pipe 51, the gas will sequentially and intermittently enter the cavity 431 through the hose 53, the frame 2 41 and the through hole 421, and finally be discharged from the bottom of the cavity 431 to clean the wood chips remaining between the brush bodies on the flower head 43.

[0059] like Figure 1-2 , Figure 5 , Figure 7-8 and Fig.10 As shown, the plurality of straight slots 511 on the fixed pipe 51 are symmetrically divided into two groups at the middle section of the fixed pipe 51;

[0060] The straight slots 511 and the hose 53 are staggered, and the two groups of straight slots 511 are initially sealed by the inner walls of the corresponding sleeves 52;

[0061] By adopting the above scheme, gas is injected into the fixed pipe 51 through the air pump. At this time, since the straight slots 511 are sealed by the sleeve 52, the pressure inside the fixed pipe 51 will increase. Combined with the design of symmetrical distribution of the two groups of straight slots 511, when the frame 31 drives the sleeve 52 to move, each group of straight slots 511 will intermittently connect the fixed pipe 51 and the corresponding hose 53, so as to quickly discharge the gas inside the fixed pipe 51, so as to improve the cleaning effect of the air pump on the brush body of the flower head 43.

[0062] The working principle and use process of the present invention:

[0063] First, the operator places the plate on the conveyor belt mechanism 11 for conveying. When the plate passes under the pressure roller 23, the plate will squeeze the pressure roller 23 upward. At this time, the pressure roller 23 will drive the ladder frame 22 and the frame body 2 41, the connecting shaft 42 and the flower head 43 upward. Therefore, when the thickness of the plate becomes thicker, it is ensured that the brush body of the flower head 43 will not scratch the surface of the plate when removing burrs on the surface and edge of the plate. At the same time, the bracket 12 supports the driving mechanism 3 as a whole, avoiding the weight of the driving mechanism 3 from being transferred to the flower head 43, and further avoiding the situation that the brush body of the flower head 43 scratches the surface of the plate.

[0064] The operation of the driving motor 32 drives the spline shaft 44 to rotate, and drives the flower head 43 to rotate through the spline shaft 44 to remove the burrs on the plate. When the crank connecting rod motor assembly 33 is running, it can push the frame 1 31 to move back and forth, and drive the frame 2 41 and the flower head 43 to move back and forth through the cooperation between the spline shaft 44 and the flower head 43, so that the brush body part of the flower head 43 reciprocates on the surface of the plate, thereby improving the burr removal effect of the device on the surface and edge of the plate;

[0065] When the conveyor belt mechanism 11 is moving while conveying the plate, the elastic rod 243 will first contact the top of the plate, and the plate will also cause the elastic rod 243 to retract into the cover body 1 241 and the cover body 242 when moving. At the same time, the ends of the multiple elastic rods 243 squeeze the plate to make the plate more stable during transportation, and the parts that are not in contact with the top of the plate will be on both sides of the plate, thereby stabilizing both sides of the plate during transportation and ensuring the stability of the flower head 43 when removing burrs from the plate.

[0066] When the frame 1 31 moves back and forth, it will also drive the sleeve 52 to reciprocate outside the fixed pipe 51, so that the fixed pipe 51 and the straight slot 511 are intermittently connected with the hose 53. Since the air pump continuously injects gas into the fixed pipe 51, the gas will sequentially and intermittently enter the cavity 431 through the hose 53, the frame 2 41 and the through hole 421, and finally be discharged from the bottom of the cavity 431 to clean the wood chips remaining between the brush bodies on the flower head 43.
