[0002] A saw is a machine tool used for sawing various metal materials. It is classified by structure into horizontal and vertical types; and by function into semi-automatic, fully automatic, and CNC types. Horizontal saws can be further divided into double-column and scissor types. With the continuous improvement of people's living standards, wooden furniture is becoming increasingly popular. However, when saws are in operation, the cutting of wood generates a large amount of dust and sawdust, which affects the health of workers and is inconvenient to collect and clean. Utility Model Content

[0003] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a saw for furniture processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A saw for furniture processing includes a workbench with a through hole. A saw blade and a drive mechanism for rotating the saw blade are respectively provided on the lower side of the workbench. The saw blade protrudes outward from the upper surface of the workbench through the through hole. A collection pipe is respectively provided on the lower side of the workbench and on both sides of the saw blade. A movable tube with an upper opening is rotatably connected to the upper end of the collection pipe. A discharge hole communicating with the inner cavity of the collection pipe is passed through the lower end of the movable tube.

[0006] The collection pipe has a first air inlet pipe and a first air outlet pipe on each side, which are connected to the inner cavity of the pipe. The first air inlet pipe and the first air outlet pipe are arranged on the same central axis. The first air inlet pipe is connected to an external exhaust device through a pipe, and the first air outlet pipe is connected to an external blower through a pipe. The movable tube has a second air inlet pipe and a second air outlet pipe on each side, which are connected to the inner cavity of the pipe. The second air inlet pipe is rotatably arranged inside the first air inlet pipe on the same central axis, and the second air outlet pipe is rotatably arranged inside the first air outlet pipe on the same central axis.

[0007] In one embodiment, the first air intake pipe has a first air inlet, the second air intake pipe has a second air inlet corresponding to the first air inlet, the first air outlet pipe has a first air outlet, and the second air outlet pipe has a second air outlet corresponding to the first air outlet. When the first air inlet and the second air inlet are connected, the first air outlet and the second air outlet are not connected to each other. Conversely, when the first air outlet and the second air outlet are connected, the first air inlet and the second air inlet are not connected to each other.

[0008] In one embodiment, the lower side of the workbench is provided with a lifting frame that can move up and down relative to it and a cylinder that can drive the lifting frame to move up and down. The saw blade and the driving mechanism are respectively disposed on the lifting frame.

[0009] In one embodiment, the workbench is provided with a transmission mechanism that drives the movable tube to swing up and down as the lifting frame moves up and down.

[0010] In one embodiment, the transmission mechanism includes a guide groove located at an angle to the horizontal plane on the lower side of the worktable, and a guide shaft protruding from one side of the movable tube, the guide shaft being movably disposed within the guide groove.

The drive wheel and the transmission wheel are connected by a sprocket and chain drive.

[0012] In one embodiment, a collection box is connected to the lower ends of the two collection pipes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model, through the cooperation of the collection pipe and the movable tube, allows the sawdust cut by the saw blade to fall directly into the collection pipe through the movable sleeve when the upper opening of the movable tube faces the through hole of the workbench. At this time, the external exhaust device can be started and the external blower is in the closed state. The dust is drawn and collected through the first air inlet pipe and the second air inlet pipe, thereby achieving the purpose of easy collection and cleaning.

[0015] Furthermore, when not in use, the movable tube can rotate relative to the collecting pipe so that the open end of the movable tube rotates toward the side of the workbench. At this time, the external blowing device can be started and the external exhaust device is in the closed state. Then, through the first air outlet pipe and the second air outlet pipe, air can be blown through the open end of the movable tube, which facilitates heat dissipation for equipment or personnel located around the workbench and improves comfort.

[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0023] like Figures 1-6 A furniture saw, as shown, includes a worktable 1 with a through hole 2. A saw blade 3 and a drive mechanism 4 for rotating the saw blade 3 are respectively provided on the lower side of the worktable 1. The saw blade 3 protrudes outward from the upper surface of the worktable 1 through the through hole 2. Collection pipes 5 are respectively provided on the lower side of the worktable 1 and on both sides of the saw blade 3. A movable tube 6 with an upper opening is rotatably connected to the upper end of the collection pipe 5. A discharge hole 7 communicating with the inner cavity of the collection pipe 5 is passed through the lower end of the movable tube 6. The collection pipe 5 has a first discharge hole 7 on each side communicating with its inner cavity. An air inlet pipe 51 and a first air outlet pipe 52 are arranged on the same central axis. The first air inlet pipe 51 is connected to an external exhaust device (not shown in the figure) through a pipe, and the first air outlet pipe 52 is connected to an external blower device (not shown in the figure) through a pipe. The movable tube 6 has a second air inlet pipe 61 and a second air outlet pipe 62 on both sides that are connected to their inner cavities. The second air inlet pipe 61 is rotatably arranged on the same central axis inside the first air inlet pipe 51, and the second air outlet pipe 62 is rotatably arranged on the same central axis inside the first air outlet pipe 52.

[0024] Specifically, by cooperating the collection pipe and the movable tube, when the upper opening of the movable tube faces the through hole of the workbench, the wood chips cut by the saw can fall directly into the collection pipe through the movable sleeve for collection. At this time, the external exhaust device can be started and the external blower is in the closed state. The dust is drawn from the opening end of the movable tube through the first air inlet pipe and the second air inlet pipe for collection, thereby achieving the purpose of easy collection and cleaning.

[0025] Furthermore, when not in use, the movable tube can rotate relative to the collecting pipe so that the open end of the movable tube rotates toward the side of the workbench. At this time, the external blowing device can be started and the external exhaust device is in the closed state. Then, through the first air outlet pipe and the second air outlet pipe, air can be blown through the open end of the movable tube, which facilitates heat dissipation for equipment or personnel located around the workbench and improves comfort.

[0026] External exhaust devices can be constructed by combining a bag filter with an exhaust fan.

[0027] An external blowing device can be a blower.

[0028] Furthermore, the first air intake pipe 51 has a first air intake port 53, the second air intake pipe 61 has a second air intake port 54 corresponding to the first air intake port 53, the first air outlet pipe 52 has a first air outlet 55, and the second air outlet pipe 62 has a second air outlet 56 corresponding to the first air outlet 55. When the first air intake port 53 and the second air intake port 54 are connected, the first air outlet 55 and the second air outlet 56 are not connected to each other. Conversely, when the first air outlet 55 and the second air outlet 56 are connected, the first air intake port 53 and the second air intake port 54 are not connected to each other.

[0029] Specifically, by rotating the movable tube relative to the collection pipe to make the air inlet and outlet closed in a staggered manner, that is, when the open end of the movable sleeve is in the upward state, the exhaust device works and the movable tube is in the dust suction state. At this time, the first air outlet and the second air outlet are not connected to each other, thereby preventing the dust after suction from entering the first air outlet and the second air outlet, and keeping the first air outlet and the second air outlet clean.

[0030] When the movable sleeve rotates relative to the collection pipe so that the open end of the movable pipe faces the side of the workbench, the first air inlet pipe and the first air outlet pipe rotate relative to the second air inlet pipe and the second air outlet pipe, respectively. As a result, the first air inlet and the second air inlet are deflected and misaligned and no longer connected to each other, while the first air outlet and the second air outlet are aligned and connected. At this time, when the blowing device is working and the movable tube is in the blowing state, the first air inlet pipe and the second air inlet pipe are in a state of no connection.

[0031] Furthermore, the lower side of the workbench 1 is provided with a lifting frame 8 that can move up and down relative to it, and a cylinder 9 that can drive the lifting frame 8 to move up and down. The saw blade 3 and the drive mechanism 4 are respectively mounted on the lifting frame 8. Thus, by driving the lifting frame up and down with the cylinder, the saw blade can be stored under the workbench when not in use, preventing accidental damage by the operator.

[0032] Furthermore, the workbench 1 is equipped with a transmission mechanism 10 that drives the movable tube 6 to swing up and down with the lifting frame 8. Further, the transmission mechanism 10 includes a guide groove 11 located at an angle to the horizontal plane on the lower side of the workbench 1, and a guide shaft 12 protruding from one side of the movable tube 6, the guide shaft 12 being movably disposed within the guide groove 11. Thus, when the cylinder drives the lifting frame to move up and down, the guide shaft of the movable tube can move along the length of the guide groove, thereby achieving relative up-and-down rotation of the movable tube relative to the collection pipe.

[0033] Furthermore, the drive mechanism 4 includes a motor 41 and a drive wheel 42 disposed on the drive shaft of the motor 41. A transmission shaft 43 is disposed at the center of one side of the saw blade 3, and a transmission wheel 44 is disposed on the transmission shaft 43. The drive wheel 42 and the transmission wheel 44 are connected by a sprocket and chain drive.

[0034] Furthermore, a collection box 45 is connected to the lower end of the two collection pipes 5, thereby achieving centralized collection of wood chips.

[0035] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
