Description

Technical Field

[0001] This utility model relates to the field of wood board drilling technology, and in particular to a wood board drilling machine. Background Technology

[0002] A drilling machine is a device that can drill holes in various materials such as wood panels. It is widely used in various fields. For example, in furniture manufacturing companies, drilling machines are often used to make holes in wood.

[0003] Currently, drilling holes in wood can be divided into blind holes and through holes (also called through holes). When drilling blind holes, since the drilling machine does not need to drill through the wood, some wood chips produced during drilling will remain in the blind hole. Therefore, after drilling blind holes in this type of wood, it is necessary to clean the blind holes of the wood. At present, the cleaning work is mainly done by workers. Existing drilling machines cannot take care of cleaning the blind holes of the wood boards, which increases the workload of workers and affects production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drilling machine for wood boards, which aims to solve the problems mentioned in the background technology.

[0005] The technical solution of this utility model is as follows: a drilling machine for wood boards includes a base, a drilling device and a conveying device for conveying wood boards are installed on the base, and this utility model also includes a dust collection device located at the output end of the conveying device. The dust collection device includes a dust collection cylinder rotatably mounted on a base and a dust collection source. The dust collection cylinder has a dust collection chamber through which a wooden board can pass. When the vacuum cleaner rotates, it can flip the wooden board inside the vacuum chamber.

[0006] The dust collection device of this utility model includes: The support rollers are rotatably mounted on the machine base; A vacuum cleaner, placed on a support roller, and having the aforementioned vacuum chamber; The gear ring is coaxially fixed to the vacuum cleaner. The drive rack is slidably connected to the base and meshes with the gear ring; The driver is mounted on the base and is used to control the reciprocating movement of the drive rack; The dust source is connected to the dust collection chamber via a dust collection pipe.

[0007] Preferably, the cross-sectional shape of the dust collection chamber is a regular polygon.

[0008] Preferably, a suction groove is recessed on the inner wall of the suction cylinder, one end of the suction pipe is connected to the suction groove, and both ends of the suction cylinder are provided with air inlets connected to the suction groove.

[0009] Preferably, the opening of the dust collection tank is flared.

[0010] By adopting the above technical solution: After drilling a hole in the wood, the drilling machine of this invention can drive the wood board to flip over, so that the side of the wood board with the blind hole faces down. Therefore, it is easy for the wood chips in the blind hole to fall off and be sucked away by the vacuum, thus completing the cleaning. Therefore, there is no need for workers to clean the wood board after drilling.

[0011] Preferably, the dust source includes a filter box and a dust pump, and the dust collection chamber, the filter box and the dust pump are connected in sequence through a dust collection pipe.

[0012] Preferably, the filter box comprises: The enclosure consists of a first enclosure, a second enclosure, and a third enclosure, which are integrally formed longitudinally. The dust inlet and exhaust outlet are located on the first housing. The mounting plate is fixed inside the first box and has several mounting ports; Columnar filter screens are fixed at each installation port; The cross-sectional cavity diameter of the second chamber gradually decreases longitudinally.

[0013] Preferably, a partition cover is fixedly connected inside the first housing, dividing the first housing into an air inlet area and an air outlet area. The dust inlet is connected to the air inlet area, and the exhaust outlet is connected to the exhaust area. A filter screen is fixedly connected to the bottom of the partition cover.

[0014] By adopting the above technical solution: The filter box of this utility model is equipped with two-stage filtration. When wood chips enter from the dust inlet, they are first filtered by the filter screen, then filtered by the columnar filter screen, and finally discharged through the exhaust port. The reduced cavity diameter of the second chamber in this invention facilitates the falling of sawdust entering the chamber through the dust inlet into the third chamber. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-7 As shown, this embodiment discloses a drilling machine for wood boards, including a base 1, on which a drilling device 2, a conveying device 3 for conveying wood boards, and a dust collection device 4 are mounted. Figure 1 For example, the conveying device and the dust collection device are distributed from right to left. That is to say, the conveying device is used to convey the wooden boards to move from right to left, and the drilling device 2 is located above the conveying device 3.

[0019] refer to Figures 2-3 In this embodiment, the drilling device 2 includes: The drilling rig support consists of a support rod 20 mounted on the base 1 and a top plate 21 fixed to the support rod; The limiting slide bar 22 is fixedly connected between the top plate 21 and the base 1; The drilling rig housing 23 is slidably connected to the limiting slide rod 22 via the limiting slide plate 24; In this embodiment, two pulleys 230 are rotatably connected inside the drill housing 23, and a belt 231 is connected between the pulleys 230. One of the pulleys 230 is controlled and driven by the drill motor 232, which is mounted on the drill housing 23. The other pulley 230 is connected to the drill bit 234 through a drive shaft 233. The drill motor 232 can control the pulley to rotate clockwise or counterclockwise.

[0020] In this embodiment, the drill housing 23 is provided with a longitudinally penetrating chamber 235. A lead screw 236 is rotatably connected between the base 1 and the top plate 21. A lead screw seat 237 is fitted on the lead screw 236. The drill housing 33 is fixed to the lead screw seat 237. The lead screw 236 passes through the chamber 235 and can be controlled by a motor (not shown in the figure, which can be installed at the bottom of the base 1) to rotate clockwise or counterclockwise. Therefore, when the lead screw 236 is driven to rotate, the drill housing 23 is controlled to rise and fall. With the help of the drill motor 232 to control the rotation of the drill bit, drilling holes in the wooden board can be completed.

[0021] refer to Figures 4-5 The conveying device 3 in this embodiment includes: The conveyor support 30 has a conveyor channel 300 for the movement of the wooden planks; The conveyor roller 31 is rotatably connected within the conveyor channel 300; The conveyor belt 32 is located within the conveying channel 300 and below the conveyor roller 31; Conveyor belt roller 33 is used to support and control the movement of conveyor belt 32.

[0022] In this embodiment, the conveyor belt roller 33 is controlled and driven by the conveyor belt motor 34, and a support plate 35 is fixed in the conveying channel 300. A chip discharge groove 30a is provided on the side of the conveying bracket 30 away from the dust collection device. Some of the wood chips generated by drilling will fall onto the conveyor belt 32 and can be discharged from the chip discharge groove 30a under the conveying of the conveyor belt 32.

[0023] In this embodiment, drive conveying rollers 37 driven by drive motor 36 are rotatably connected to both ends of the conveying channel 300. There are two drive conveying rollers 37 on the side of the conveying channel 300 near the dust collection device (and one drive conveying roller on the other side). The drive motor 36 drives the drive conveying rollers 37 below to rotate. In this embodiment, the distance between the drive conveying rollers is greater than the thickness of the wooden board. When conveying the wooden board, the wooden board is placed on the drive conveying roller and the wooden board is controlled to move forward when the drive conveying roller rotates. When the wooden board reaches the drilling area, it stops and then the drilling device drills holes in the wooden board. After the drilling is completed, a new wooden board can be put in to continue conveying. The new wooden board will push the wooden board that has finished drilling forward and enter the dust collection device.

[0024] In this embodiment, the purpose of the distance between the drive conveyor rollers being greater than the thickness of the wooden board is that when the wooden board is drilled, wood chips will temporarily remain on the previous board. Therefore, the drive conveyor rollers are used to prevent the edges of the wooden board from warping during transport (so they generally do not contact the wooden board, as contact would easily squeeze the wood chips and damage the wooden board), thereby allowing the wooden board to smoothly enter the dust collection device.

[0025] In this embodiment, a clamping structure is also hinged on the conveying bracket 30. The clamping structure includes a hinge seat 390 and a clamping frame 391 rotatably connected to the hinge seat 390 via a shaft. The base 1 is also provided with a clamping cylinder 392. The output end of the clamping cylinder 392 is fixedly connected to a drive shaft 393. The clamping frame 391 is provided with a drive groove 394 for the drive shaft 393 to slide. During drilling, the clamping cylinder 392 controls one end of the hinge frame to rise, and the drive shaft slides in the drive groove. Then, the wooden board is clamped by one end of the clamping frame 391, thereby ensuring the stability of the drilling.

[0026] refer to Figures 6-7 The vacuum cleaner 4 in this embodiment includes: The support roller 40 is rotatably mounted on the base 1. The base 1 is equipped with a support roller frame 41.

The vacuum cleaner 41 is placed on the support roller 40 and has the vacuum chamber 410. The outer wall of the vacuum cleaner 41 is also provided with a limiting ring 411, which is placed in the recess of the support roller (referring to the recessed position of the circumferential side wall of the support roller). The gear ring 42 is coaxially fixed to the dust collection cylinder 41; Drive rack 43, which is slidably connected to base 1 and meshes with gear ring 42; The driver 44 is mounted on the base 1 and is used to control the reciprocating movement of the drive rack 43. The driver 44 is a cylinder. The dust source is connected to the dust chamber via the dust suction pipe 45.

[0027] In this embodiment, the cross-sectional shape of the suction chamber 410 is a regular polygon, and the cross-sectional shape of the suction chamber 410 in this embodiment is a square.

[0028] In this embodiment, a lifting seat 10a is provided on the base 1, and a support roller 40 is provided on the lifting seat 10a.

[0029] In this embodiment: a suction groove 46 is recessed on the inner side wall of the suction cylinder 41, one end of the suction pipe 45 is connected to the suction groove 46, and air inlets 47 connected to the suction groove 46 are provided at both ends of the suction cylinder 41.

[0030] In this embodiment, the opening of the dust collection groove 46 is flared, that is, trumpet-shaped, and the width of the opening is greater than the width of the bottom of the groove.

[0031] In this embodiment, the dust source includes a filter box and a dust pump 50 (or a high-pressure blower, which is a mature existing technology, and the specific structure will not be described in detail in this embodiment). The dust suction chamber 410, the filter box, and the dust pump 50 are connected in sequence through a dust suction pipe.

[0032] In this embodiment, the suction pipe 45 is composed of a first pipe body 451, a second pipe body 452, a third pipe body 453, and a fourth pipe body 454. The first pipe body 451, the second pipe body 452, and the third pipe body 453 are connected end to end. The fourth pipe body 454 connects the dust pump 50 and the filter box. In this embodiment, the second pipe body 452 can be bent (such as a flexible hose). When selecting a flexible hose, a flexible hose that can be fully bent but will not close due to internal bending can be selected to ensure the continuity of suction.

[0033] In this embodiment: the filter box includes: The box body is composed of a first box body 61, a second box body 62, and a third box body 63, which are integrally formed longitudinally; Dust inlet 64 and exhaust outlet 65 are located on the first housing 61; Mounting plate 66 is fixed inside the first housing 61 and has several mounting ports; Columnar filter screen 67 is fixed at each installation port; Among them, the cross-sectional cavity diameter of the second box 62 gradually decreases longitudinally.

[0034] In this embodiment: a partition cover 68 is fixedly connected inside the first housing 61. The partition cover 68 divides the first housing 61 into an air intake area and an exhaust area. The dust inlet 64 is connected to the air intake area, and the exhaust outlet 65 is connected to the exhaust area. A filter screen 69 is fixedly connected to the bottom of the partition cover 68.

[0035] In this embodiment, the mesh size of filter 69 is larger than that of columnar filter 67. When the airflow passes through the filter and columnar filter once, secondary filtration is completed.

[0036] In this embodiment, the mounting plate is fixed to the partition cover 68.

[0037] In this embodiment, the box body is detachable by bolts, with a first sealing plate 71 and a second sealing plate 72. The partition cover can be removed for cleaning by opening the first sealing plate, and impurities inside the box can be discharged by opening the second sealing plate.

[0038] In this embodiment, the width of the wooden board 100a is slightly smaller than the width of the dust collection chamber.

[0039] refer to Figure 6-7 The principle of this embodiment is: After the wooden board is drilled, it is fed into the vacuum chamber (with the blind holes facing upwards). The vacuum trough is located on one side of the wooden board. The vacuum cylinder is driven to rotate counterclockwise by the cylinder, rack, and gear ring (it stops after rotating 90 degrees). During the rotation, the vacuum trough moves from one side to the bottom, while the wooden board moves from the bottom to one side. Its supporting surface is a relatively narrow side, so the center of gravity changes (plus the inertia generated by the movement of the vacuum cylinder). The wooden board will flip over, with the blind holes facing downwards and aligned with the vacuum trough. Then, the vacuum pump is started to remove the impurities in the blind holes, completing the cleaning.

[0040] After cleaning is complete, the cylinder controls the vacuum tube to rotate clockwise, causing the vacuum tube to return to its original position. When the next wooden board enters the vacuum chamber, it will push the cleaned wooden board out of the vacuum chamber from one end of the vacuum tube.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
