Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to wood processing equipment for producing fireproof doors. Background Art

[0002] With the continuous development of the construction industry and people's attention to fire safety, fire doors are one of the indispensable fire-fighting equipment in buildings. The production of fire doors is inseparable from efficient and precise wood processing equipment. In the production process of fire doors, electronic cutting saws are widely used for wood cutting and cutting operations. Electronic cutting saws have the advantages of high degree of automation, fast cutting speed and easy operation, making them one of the indispensable equipment in wood processing.

[0003] However, the existing electronic saws have some shortcomings during use:

[0004] 1. After the wood is cut according to the processing requirements, manual intervention is usually required to transfer the cut wood to the storage rack and stack it. This process is not only time-consuming and labor-intensive, but also increases the workload of the operators and affects the subsequent transportation efficiency;

[0005] 2. After the electronic saw has been running for a long time, the cutting quality will be reduced due to wear of the blade edge, which is manifested in large burrs on the edge of the wood and increased dimensional errors. When the dimensional error exceeds the allowable range, it will also cause subsequent assembly difficulties, increased scrap rate and cost.

[0006] Based on the above problems, this application document proposes a wood processing equipment for fire door production to improve the above problems. Summary of the invention

When the cut wood slides to the upper end of the stacking bottom plate, the pressure sensor will be triggered to monitor the pressure change of the stacking bottom plate, and the driving unit will be started to lower the stacking bottom plate to facilitate stacking of the cut wood, thereby reducing the need for manual handling. At the same time, the wood is tightly fitted to the limit plate, and the elastic element will drive the reference plate to move until it is tightly fitted to the wood.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] Please refer to the attached Figures 1 to 4 As shown, it is the first embodiment of the present invention, which provides a wood processing equipment for producing fire doors, including a main body 10, wherein a feeding module 11 and a material coding bottom plate 13 are respectively installed at both ends of the main body 10, and a material coding bottom plate 13 is provided at one end of the material coding bottom plate 13, and a cutting module 14 and an electrical control module 15 are installed on the main body 10, and the feeding module 11 and the electrical control module 15, the material coding bottom plate 13 and the electrical control module 15, and the cutting module 14 and the electrical control module 15 are all electrically connected through wires, and further comprising:

[0047] The scissor-type lifting mechanism 20 includes a lower bottom plate 21, an upper bottom plate 22, a driving unit 23 and a scissor-type connecting rod 24. The lower bottom plate 21 is arranged at one end of the air-floating workbench 12 and is located at the lower end of the material-coding bottom plate 13. The upper bottom plate 22 is arranged at the upper end of the lower bottom plate 21 and is located at the lower end of the material-coding bottom plate 13. A plurality of pressure sensors are evenly arranged between the upper bottom plate 22 and the material-coding bottom plate 13. The driving unit 23 is arranged inside the lower bottom plate 21, wherein a servo motor is arranged inside the driving unit 23, and the servo motor and the electrical control module 15 are electrically connected through a wire. The scissor-type connecting rod 24 is arranged between the lower bottom plate 21 and the upper bottom plate 22, and the driving unit 23 and the scissor-type connecting rod 24 are connected. The driving unit 23 can drive the scissor-type connecting rod 24 to extend or contract.

[0048] The limiting part 30 is assembled inside the scissor-type lifting mechanism 20, and the limiting part 30 can limit the cut wood;

[0049] A size detection unit 40, which is mounted at the lower end of one end of the material stacking bottom plate 13, and can detect the edge of the topmost wood at the upper end of the material stacking bottom plate 13;

[0050] Among them, the upper end of the material coding bottom plate 13 is higher than the upper end of the upper bottom plate 22 in the vertical direction. After the pressure sensor detects that the pressure at the upper end of the material coding bottom plate 13 changes, the scissor-type lifting mechanism 20 can drive the material coding bottom plate 13 to move in the vertical direction.

[0051] It should be noted that the feeding module 11 can clamp the wood raw materials and drive the wood raw materials to move, the cutting module 14 can cut the wood raw materials, and after the driving unit 23 is operated, the scissor-type connecting rod 24 can extend or contract, and then drive the upper base plate 22 to move in the vertical direction through the scissor-type connecting rod 24. Specifically, the feeding module 11, the cutting module 14, and the scissor-type lifting mechanism 20 composed of the lower base plate 21, the upper base plate 22, the driving unit 23 and the scissor-type connecting rod 24 are all existing mature technologies, and their detailed working process and working principle will not be further elaborated here.

[0052] In this embodiment, the wood raw material is clamped by the feeding module 11, and the wood raw material is driven to move in the direction close to the cutting module 14. According to production requirements, the wood raw material is cut by the cutting module 14. Under the guidance of the operator, the cut wood slides one by one to the surface of the material stacking bottom plate 13 through the air flotation workbench 12, and the wood is allowed to fit with the limiting portion 30. The limiting portion 30 forms a limit on the wood. The pressure change at the upper end of the material stacking bottom plate 13 is monitored by the pressure sensor, and the signal is transmitted to the electrical control module 15. The driving unit 23 is started by the electrical control module 15, so that the driving unit 23 drives the upper bottom plate 22 to move downward. In this process, each time the pressure on the surface of the material stacking bottom plate 13 increases, the driving unit 23 drives the upper bottom plate 22, the material stacking bottom plate 13 and the wood located at the upper end of the material stacking bottom plate 13 to move downward once. The edge of the wood that slides on the upper end of the material stacking bottom plate 13 is detected by the size detection unit 40, and then it is determined whether the size of the wood exceeds the allowable tolerance range.

[0053] Furthermore, the thickness of the wood is inputted through the electrical control module 15 , and the thickness of the wood after cutting is the same as the moving distance of the upper base plate 22 driven by the driving unit 23 in the vertical direction each time.

[0054] It should be noted that, among all the wood that has been cut and is located at the upper end of the stacking bottom plate 13 , the size detection unit 40 only monitors the edge of the wood located at the uppermost end.

[0055] In a specific embodiment, when the upper bottom plate 22 moves to the lowermost end and the wood on the upper end of the stacking bottom plate 13 is stacked to the maximum number, it can be transported in one go by transportation equipment such as a forklift.

[0056] Next, please refer to Figure 1 to Figure 2 As shown, a sliding surface 16 is integrally formed at one end of the air flotation workbench 12 close to the coding bottom plate 13, and the sliding surface 16 is in an inclined state. In the initial state, the sliding surface 16 is located at the upper end of the coding bottom plate 13, and the inclination angle of the sliding surface 16 in the horizontal direction ranges from 5° to 60°. Preferably, in this embodiment, the angle between the sliding surface 16 and the horizontal plane is preferably 20°.

[0057] In this embodiment, after the cut plate slides to the surface of the sliding surface 16, the plate can quickly slide to the surface of the stock base plate 13 under the action of gravity. Since the sliding surface 16 is inclined relative to the horizontal plane, the plate can fit with the limit portion 30 under the action of inertia during the sliding process. There is no need to manually move the plate to the surface of the stock base plate 13. The operator only needs to check whether the plate fits with the limit portion 30, which is convenient for the operator to operate.

[0058] Secondly, please also refer to Figure 4 and Figure 6 The limiting part 30 includes a threaded rod 31, a plurality of first guide rods 32, a crossbeam 33, a handwheel 34, a plurality of sliders 35, a plurality of second guide rods 36 and a plurality of limiting plates 37. The threaded rod 31 is rotatably connected to the interior of the upper base plate 22 through a ball bearing. The plurality of first guide rods 32 are respectively fixed to both sides of the interior of the upper base plate 22. The crossbeam 33 is slidably connected to the outer sides of the plurality of first guide rods 32, and the crossbeam 33 is threadedly connected to the threaded rod 31. The handwheel 34 is fixed to one end of the outer side of the threaded rod 31 and is located outside the main body 10. The plurality of sliders 35 are respectively slidably connected to the plurality of The outer side of the first guide rod 32, and the cross beam 33 and the slider 35 are fixedly connected, multiple second guide rods 36 are respectively fixed on both sides of the lower base plate 21, and the multiple first guide rods 32 and the multiple second guide rods 36 correspond one by one, and the multiple limit plates 37 are respectively slidably connected to the outer sides of the multiple second guide rods 36, and the multiple limit plates 37 and the multiple sliders 35 as well as the multiple limit plates 37 and the multiple clearance grooves 25 correspond one by one, and the corresponding sliders 35 and the limit plates 37 are slidably connected, wherein, in the initial state, the corresponding limit plates 37 penetrate the inside of the clearance groove 25.

[0059] Specifically, guide grooves are provided at both ends of the slider 35, a guide groove is provided inside the limiting plate 37, and guide bosses 38 are provided at both ends of the guide groove. The guide grooves and the guide bosses 38 are adapted to each other, and the slider 35 and the limiting plate 37 are slidably connected through the guide grooves and the guide bosses 38.

[0060] In this embodiment, the hand wheel 34 is rotated to drive the threaded rod 31 to rotate, and the threaded rod 31 and the cross beam 33 are threadedly connected, so that the threaded rod 31 drives the cross beam 33 to move along the extension direction of the threaded rod 31. Since the cross beam 33 and the slider 35 are fixedly connected, and the slider 35 and the limit plate 37 are slidably connected, the cross beam 33 drives the slider 35 and the limit plate 37 to move along the extension direction of the threaded rod 31, so that the limit plate 37 can limit the wood of different sizes. At the same time, when the wood is cut, The wood pieces slide down to the upper end of the material stacking bottom plate 13 one by one, and after the driving unit 23 drives the upper bottom plate 22 to move downward, the upper bottom plate 22 drives the first guide rod 32 and the slider 35 to move downward synchronously through the fixed connection between the upper bottom plate 22 and the first guide rod 32. During this process, the limit plate 37 is in a stationary state. Through this arrangement, the limit plate 37 can limit wood pieces of different sizes, and can also keep the wood in a limited state during the process in which the upper bottom plate 22 drives the material stacking bottom plate 13 to move downward.

[0061] Please refer again Figure 2 and Figure 4 A plurality of scale marks are evenly arranged on the upper end of the coding bottom plate 13 , and the scale marks are matched with the limit plate 37 .

[0062] In this embodiment, the setting of the scale mark facilitates the operator to accurately adjust the position of the limit plate 37 so that the horizontal distance between the limit plate 37 and the sliding surface 16 can be adapted to the size of the cut wood.

[0063] Please refer again Figures 7 to 9 As shown, the size detection part 40 includes a shell 41, a support plate 42, a linkage guide rod 43, a reference plate 44, a distance sensor 45 and an elastic element 46. The shell 41 is fixed to the lower end of the air floating workbench 12, close to the material coding bottom plate 13. The end of the shell 41 close to the material coding bottom plate 13 is provided with an avoidance groove 47. The support plate 42 is fixed to the inside of the shell 41. The linkage guide rod 43 is slidably connected to the inside of the support plate 42. The reference plate 44 is fixed to the end of the linkage guide rod 43 close to the material coding bottom plate 13, and the reference plate 44 and the avoidance groove 47 are matched. The distance sensor 45 is fixed to the end of the shell 41 away from the material coding bottom plate 13. The distance sensor 45 and the electrical control module 15 are electrically connected through a wire, and the distance sensor 45 and the linkage guide rod 43 are matched. The elastic element 46 is assembled between the linkage guide rod 43 and the shell 41 and is located on the outside of the distance sensor 45.

[0064] It should be noted that when the scissor-type connecting rod 24 is in the maximum extended state, the vertical distance between the upper base plate 22 and the lower base plate 21 is the largest. At this time, the upper end of the material coding base plate 13 is slightly lower than the lower end of the reference plate 44, avoiding the upper end of the material coding base plate 13 and the reference plate 44 from fitting closely, causing the reference plate 44 to be unable to move.

[0065] In this embodiment, when the cut plates slide down one by one to the upper end of the coding bottom plate 13 through the sliding surface 16, and one end of the wood is tightly fitted with the limit plate 37, the wood at the uppermost end pushes the reference plate 44 to move in the direction close to the distance sensor 45. At the same time, the elastic element 46 is squeezed. Since the elastic element 46 has a rebound characteristic, the reference plate 44 and the wood are pushed to fit tightly together by the elastic element 46. The distance sensor 45 measures the distance between the sensing end and the linkage guide rod 43, and then calculates whether the size of the cut wood exceeds the tolerance range. At the same time, it can also judge the degree of wear of the blade (the greater the degree of wear of the blade, the greater the size error of the cut wood). When the blade wear is large, the electrical control module 15 sends a reminder to the operator, so that the operator can maintain or replace the blade in time to improve product quality and avoid problems such as dimensional tolerance, edge burrs, and subsequent assembly difficulties.

[0066] In a specific embodiment, if the width of the wood after cutting is required to be 100 cm and the width dimension tolerance is ±1 cm, in the initial state, the hand wheel 34 is turned to adjust the position of the limit plate 37 according to the width requirement and the tolerance range, so that the distance between the limit plate 37 and the reference plate 44 is 99 cm. After the cut wood falls to the upper end of the coding bottom plate 13 and the limit plate 37 and the wood as well as the reference plate 44 and the wood are tightly fitted, if the moving distance of the linkage guide rod 43 is less than or equal to 0, it means that the wood width is less than or equal to 99 cm, the blade wear is large, and timely maintenance is required; if the moving distance of the linkage guide rod 43 is between 0 cm and 2 cm, it means that the wood width meets the standard and the blade wear is small; if the moving distance of the linkage guide rod 43 is greater than or equal to 2 cm, it means that the wood width is greater than or equal to 101 cm of the main body, the blade wear is large, and timely maintenance is required.

[0067] It should be noted that after the wood slides to the upper end of the stacking bottom plate 13 , if the wood fails to fit tightly against the limiting plate 37 , an operator needs to intervene to push the wood until the wood fits tightly against the limiting plate 37 .

[0068] Please refer again Figure 8 and Fig. 9A guide plate 48 is integrally formed at the upper end of the reference plate 44, and the guide plate 48 is in an inclined state. The inclination angle of the guide plate 48 in the vertical direction ranges from 10° to 50°, and the guide plate 48 and the avoidance groove 47 are adapted to each other. A supporting rib is arranged between the guide plate 48 and the linkage guide rod 43. In the initial state, the upper end of the guide plate 48 is located inside the shell 41. Preferably, in this embodiment, the angle between the guide plate 48 and the vertical plane is 25°.

[0069] In this embodiment, the guide plate 48 can guide the wood as it slides down, preventing the reference plate 44 from obstructing the sliding wood and preventing the wood from completely sliding down to the upper end of the stacking bottom plate 13 .

[0070] Please refer again Figure 8 The outer side of the linkage guide rod 43 is provided with a chamfered surface, and the inner side of the support plate 42 is provided with a rotation-stopping surface, and the chamfered surface and the rotation-stopping surface are matched.

[0071] In this embodiment, the provision of the anti-rotation surface and the chamfered edge surface can prevent the linkage guide rod 43 from rotating during the movement, thereby preventing the guide plate 48 from rotating.

[0072] The working principle of the present invention is:

[0073] According to the width size and width tolerance of the wood, the hand wheel 34 is turned to adjust the distance between the limit plate 37 and the reference plate 44, the wood raw material is clamped by the feeding module 11, and the wood raw material is driven to move in the direction close to the cutting module 14, and the wood raw material is cut by the cutting module 14. Under the guidance of the operator, the cut wood slides one by one to the surface of the material stacking bottom plate 13 through the air floating workbench 12, and the wood is limited by the limit plate 37, and the reference plate 44 and the limit plate 37 are both in contact with the two sides of the uppermost wood. The moving distance of the linkage guide rod 43 is monitored by the distance sensor 45, and the linkage guide rod 43 is adjusted according to the movement distance of the linkage guide rod 43. The amount of movement is used to calculate whether the width of the cut wood exceeds the tolerance range. At the same time, the degree of wear of the tool can also be judged. At the same time, the pressure sensor is used to monitor the pressure change on the upper end of the coding bottom plate 13, and the signal is transmitted to the electrical control module 15. The driving unit 23 is started by the electrical control module 15, so that the driving unit 23 drives the upper bottom plate 22 to move downward. During this process, each time the pressure on the surface of the coding bottom plate 13 increases, the driving unit 23 drives the upper bottom plate 22, the coding bottom plate 13 and the wood located at the upper end of the coding bottom plate 13 to move downward once, and then the width of each piece of cut wood is detected by the size detection unit 40.

[0074] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
