Description

Technical Field

[0001] This utility model relates to the field of wood flooring processing technology, specifically a wood flooring grooving machine. Background Technology

[0002] Wooden flooring is widely used in furniture manufacturing, decoration and other fields due to its good performance. In the processing of wooden flooring, in order to meet the splicing requirements during installation, the wooden flooring is usually grooved, which requires the use of a wooden flooring grooving machine.

[0003] When existing grooving machines are working, they usually drive the grooving cutter to rotate, and at the same time, the wooden flooring is fed to the rotating grooving cutter at a constant speed by a conveyor belt. The grooving cutter cuts the wooden flooring to create the required grooves.

[0004] Existing grooving machines have the following problems: when wooden floorboards are transported to the processing position via conveyor belt, the wooden floorboards may shift during transportation, which affects the grooving accuracy of the wooden floorboards and reduces the pass rate of finished products. To address this, we propose a wooden floorboard grooving machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a grooving machine for processing wooden flooring. The machine guides the wooden flooring during transportation through a guiding mechanism to prevent the wooden flooring from shifting, thus avoiding the situation where the grooving accuracy of the wooden flooring is affected by the shifting of the wooden flooring, improving the qualification rate of the finished product, and effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grooving machine for processing wooden flooring, including a grooving frame, an adjustable grooving tool on the upper surface of the grooving frame, and a guiding mechanism;

[0007] The guiding mechanism includes a connecting plate, a guide plate, a U-shaped seat, a limiting groove, a rubber pad, and a drive assembly. Adjustable connecting plates are provided on both the front and rear sides of the grooving frame via the drive assembly. A guide plate is rotatably connected to the right end of each connecting plate, and a U-shaped seat is rotatably connected to the right end of each guide plate. Limiting grooves are provided on both the front and rear walls of the grooving frame. The end of the U-shaped seat furthest from the center of the grooving frame is slidably connected to the interior of an adjacent limiting groove. A rubber pad is provided on the side of the connecting plate and the guide plate on the same side closest to the center of the grooving frame. This guiding mechanism guides the wooden flooring during transport, preventing it from shifting and avoiding any impact on the grooving accuracy of the wooden flooring due to shifting, thus improving the finished product's pass rate.

[0008] Furthermore, it also includes a microcontroller, which is located on the front side of the slotting frame. The input terminal of the microcontroller is electrically connected to an external power supply to facilitate the normal operation of the equipment.

[0009] Furthermore, the drive assembly includes a slide groove, a bidirectional lead screw, and a slider. A slide groove is provided on the left side of the upper surface of the grooving frame. A bidirectional lead screw is rotatably connected inside the slide groove. Sliders are threadedly connected to both the front and rear sides of the outer surface of the bidirectional lead screw. The sliders are slidably connected inside the slide groove. The lower surface of each slider is fixedly connected to the upper surface of the adjacent connecting plate, which facilitates the normal operation of the drive guide mechanism.

[0010] Furthermore, a motor is provided on the front side of the grooving frame. The rear end of the output shaft of the motor is fixedly connected to the front end of the bidirectional lead screw. The input end of the motor is electrically connected to the output end of the microcontroller to provide driving force.

[0011] Furthermore, both the left and right sides of the grooving frame are rotatably connected to conveyor rollers via rotating shafts, and the two conveyor rollers are connected by a conveyor belt. A second motor is provided on the front side of the grooving frame. The rear end of the output shaft of the second motor is fixedly connected to the front end of the rotating shaft on the right side. The input end of the second motor is electrically connected to the output end of the microcontroller, which facilitates the transportation of wooden flooring.

[0012] Furthermore, a lead screw is rotatably connected inside the slot on the upper surface of the grooving frame. A sliding seat is threaded onto the outer surface of the lead screw. The upper end of the sliding seat is slidably connected to the inside of the slot. A grooving tool is rotatably connected to the lower end of the sliding seat via a rotating shaft. Motor 3 and Motor 4 are respectively provided on the front side of the sliding seat and the grooving frame. The rear ends of the output shafts of Motor 3 and Motor 4 are fixedly connected to the rotating shaft and the front end of the lead screw, respectively. The input ends of Motor 3 and Motor 4 are electrically connected to the output end of a microcontroller, which facilitates the adjustment of the position of the grooving tool and the control of the grooving tool's operation.

[0013] Furthermore, the upper left side and rear wall of the grooving frame are equipped with distance measuring sensors, which are bidirectionally electrically connected to the microcontroller to facilitate distance measurement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This wood flooring grooving machine has the following advantages:

[0015] The rotation of the bidirectional lead screw drives the connecting plate to move along the groove via the slider. Since the lengths of the connecting plate and the guide plate are fixed, the movement of the connecting plate drives the guide plate to rotate under the constraint of the U-shaped seat and the limiting groove. Until the distance sensor measures the actual width of the wooden floor, the distance between the two connecting plates is adjusted to guide and limit the wooden floor of that width with a reasonable spacing between the two connecting plates. This avoids the situation where the grooving accuracy of the wooden floor is affected by the offset of the wooden floor, and improves the qualification rate of the finished product.

(A corrugated tube is fitted onto the exposed part of the outer surface of the lead screw 8. The ends of the corrugated tube are fixedly connected to the side of the slot and the side of the sliding seat 9, respectively. The corrugated tube has sufficient length so that when the sliding seat 9 moves, one side of the corrugated tube contracts and the other side extends, ensuring that the corrugated tube always covers and shields the lead screw 8 during operation, preventing dust from affecting its operation.) (Threaded drive between lead screw 8 and sliding seat 9). The upper end of sliding seat 9 is slidably connected to the inside of the slot. The lower end of sliding seat 9 is rotatably connected to grooving tool 10 via a rotating shaft. Motor 3 11 and motor 4 12 are respectively provided on the front side of sliding seat 9 and grooving frame 1. The rear ends of the output shafts of motor 3 11 and motor 4 12 are fixedly connected to the rotating shaft and the front end of lead screw 8, respectively. The input ends of motor 3 11 and motor 4 12 are electrically connected to the output end of microcontroller 2, respectively. Distance sensors 13 are provided on the left side and rear wall of the upper surface of grooving frame 1. (Distance sensor 13 is a laser sensor. When working, distance sensor 13 emits a short laser pulse and then measures the laser pulse from emission to reflection from the measured object and reception by distance sensor 13.) The distance between the ranging sensor 13 and the object being measured is calculated by taking into account the time elapsed and the speed of laser propagation in air, thus obtaining the required parameters. The left ranging sensor 13 is aligned with the rear side of the slider 363, and the right ranging sensor 13 is aligned with the rear side of the grooving tool 10. Both ranging sensors 13 are bidirectionally electrically connected to the microcontroller 2. The operator operates the microcontroller 2 to activate motor 4 12. The output shaft of motor 4 12 drives the lead screw 8 to rotate. The rotation of the lead screw 8 causes the threaded sliding seat 9 to slide along the groove. Under the action of the ranging sensor 13, the position of the grooving tool 10 is precisely adjusted. Then, motors 2 7 and 3 11 are activated. The output shaft of motor 2 7 drives the right-side conveyor roller 5 to rotate.Conveyor roller 5 transports the wooden floorboards from right to left via conveyor belt 6, and motor 3 11 drives the grooving cutter 10 to rotate via a rotating shaft to perform grooving work on the moving wooden floorboards;

[0024] Guide mechanism 3: It includes a connecting plate 31, a guide plate 32, a U-shaped seat 33, a limiting groove 34, a rubber pad 35, and a drive assembly 36. Adjustable connecting plates 31 are provided on both the front and rear sides of the grooving frame 1 via the drive assembly 36. A guide plate 32 is rotatably connected to the right end of each connecting plate 31, and a U-shaped seat 33 is rotatably connected to the right end of each guide plate 32. Limiting grooves 34 are provided on both the front and rear walls of the grooving frame 1. The end of the U-shaped seat 33 furthest from the center of the grooving frame 1 is slidably connected to the interior of an adjacent limiting groove 34. A rubber pad 35 is provided on the side of the connecting plate 31 and the guide plate 32 on the same side closest to the center of the grooving frame 1. The drive assembly 36 includes a sliding groove 361, a bidirectional lead screw 362, and a slider 363. A bellows is fitted onto the exposed portion of the outer surface of the rod 362. The ends of the bellows are fixedly connected to the side of the groove 361 and the side of the slider 363, respectively. The bellows has sufficient length so that when the slider 363 moves, one side of the bellows contracts and the other side extends, ensuring that the bellows always covers and shields the bidirectional lead screw 362 during operation, preventing dust from affecting the threaded transmission of the bidirectional lead screw 362 and the slider 363. A groove 361 is formed on the left side of the upper surface of the grooving frame 1. The bidirectional lead screw 362 is rotatably connected inside the groove 361. Slider 363 is threadedly connected to both the front and rear sides of the outer surface of the bidirectional lead screw 362. The slider 363 is slidably connected inside the groove 361. The lower surface of each part is fixedly connected to the upper surface of the adjacent connecting plate 31. The front side of the grooving frame 1 is equipped with motor 4. The rear end of the output shaft of motor 4 is fixedly connected to the front end of the bidirectional lead screw 362. The input end of motor 4 is electrically connected to the output end of microcontroller 2. The operator operates microcontroller 2 to turn on motor 4 12. The output shaft of motor 4 12 drives lead screw 8 to rotate. The rotation of lead screw 8 drives the threaded sliding seat 9 to slide along the groove. Under the action of distance sensor 13, the position of grooving tool 10 is precisely adjusted. Then, motor 2 7 and motor 3 11 are turned on. The output shaft of motor 2 7 drives the right-side conveyor roller 5 to rotate. The conveyor roller 5 transports the wooden floor from right to left through conveyor belt 6. Motor 3 11 drives the wooden floor through the rotating shaft. The grooving cutter 10 rotates to groove the moving wooden floorboards. Simultaneously, motor 4 is activated, and its output shaft drives the bidirectional lead screw 362 to rotate. The rotation of the lead screw 362 causes the threaded sliders 363 on both sides to move along the groove 361. The movement of the sliders 363 causes the connecting plate 31 to move accordingly. Since the lengths of the connecting plate 31 and the guide plate 32 are fixed, under the constraint of the U-shaped seat 33 and the limiting groove 34, the movement of the connecting plate 31 causes the guide plate 32 to rotate until, under the measurement of the distance sensor 13, the distance between the two connecting plates 31 is adjusted according to the actual width of the wooden floorboards to achieve a reasonable guide and limit for the width of the wooden floorboards. Then, motor 4 is turned off.At this point, the wooden floorboards are cut in the correct orientation by the grooving tool 10 under the combined action of the guide plate 32 and the connecting plate 31. The presence of the rubber pad 35 reduces damage to the wooden floorboards.

[0025] The working principle of the wood flooring grooving machine provided by this utility model is as follows: The operator operates the microcontroller 2 to turn on motor 4 12. The output shaft of motor 4 12 drives the lead screw 8 to rotate. The rotation of the lead screw 8 causes the threaded sliding seat 9 to slide along the groove. Under the action of the distance sensor 13 (located on the rear wall of the grooving frame 1, the distance sensor 13 is directly opposite the grooving cutter 10 and can measure the distance between the distance sensor 13 and the grooving cutter 10 in real time. The distance sensor 13 transmits the detected distance data to the microcontroller 2), the position of the grooving cutter 10 is precisely adjusted. Then, motors 2 7 and 3 11 are turned on. The output shaft drives the right-side conveyor roller 5 to rotate. The conveyor roller 5 transports the wooden floorboards from right to left via the conveyor belt 6. The motor 311 drives the grooving cutter 10 to rotate and grooves the moving wooden floorboards via its rotating shaft. At the same time, the motor 4 is turned on. The output shaft of the motor 4 drives the bidirectional lead screw 362 to rotate. The rotation of the bidirectional lead screw 362 causes the threaded sliders 363 on both sides to move along the slide groove 361. The movement of the sliders 363 causes the connecting plate 31 to move accordingly. Since the lengths of the connecting plate 31 and the guide plate 32 are fixed, under the constraint of the U-shaped seat 33 and the limiting groove 34, the movement of the connecting plate 31 drives the guide plate. 32. Rotate until, under the measurement of the distance sensor 13, (the distance sensor 13 located on the left side of the slotting frame 1 is directly opposite the rear connecting plate 31, and can measure the distance between the distance sensor 13 and the rear connecting plate 31 in real time. Because the two connecting plates 31 are symmetrically arranged, and the slider 363 and the connecting plate 31 form a guide swing arm structure, and the swing arm structure is threaded to the symmetrical thread of the bidirectional lead screw 362, the front and rear structures are symmetrical, so the position of the rear slider 363 is known, and the position of the front slider 363 is specific. For example, initially, the distance between the two sliders 363 is a, and at this time the distance between the distance sensor 13 and the rear slider 363 is b). When the distance between the distance sensor 13 and the rear slider 363 is measured as c, the distance between the two sliders 363 is a-2*(cb). The distance sensor 13 presents the detected distance data to the microcontroller 2 to determine the distance between the two sliders 363. Based on the actual width of the wooden floor, the distance between the two connecting plates 31 is adjusted so that the reasonable spacing between the two connecting plates 31 guides and limits the wooden floor of that width. Then, the motor 4 is turned off. At this time, the wooden floor is cut by the grooving tool 10 in the correct orientation under the combined action of the guide plate 32 and the connecting plate 31. Due to the presence of the rubber pad 35, the damage to the wooden floor is reduced.

[0026] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32F1, the motors 4, 7, 11, and 12 can be YP-100 series, and the ranging sensor 13 can be an LTF laser sensor. The microcontroller 2 controls the operation of the motors 4, 7, 11, 12, and 13 using methods commonly used in the prior art.
