Description

Technical Field

[0001] This utility model relates to the field of dust collection technology, and in particular to a saw dust collection bin. Background Technology

[0002] The process of making wooden combs involves slicing and cutting the wood into pieces, then processing the toothed surfaces of the wood blocks, and finally aligning and sanding the surfaces. Both the wood cutting and sanding processes generate a lot of saw dust, which flies around and affects the workshop environment.

[0003] Currently, most sawdust collection is done using vacuum equipment, which collects the sawdust into a collection chamber through a vacuum pipe. However, after continuous vacuuming, the filter screen in the existing collection chamber becomes clogged with sawdust, requiring manual cleaning by stopping the machine, which is quite troublesome. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a saw dust collection bin. This collection bin adopts a pair of collection chambers that intermittently switch between collection. The switching process can automatically clean the filter screen without requiring manual cleaning during machine shutdown. Furthermore, it can compress the collected saw dust into dust blocks, which is beneficial for centralized processing.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A sawdust collection chamber includes a chamber body. From top to bottom, the chamber body comprises an installation chamber, a negative pressure chamber, and a collection chamber. The installation chamber and the negative pressure chamber are separated by a horizontal partition. A filter screen is installed between the negative pressure chamber and the collection chamber. A vertical partition is fixedly installed inside the collection chamber. A rotating shaft passing through the filter screen is rotatably connected to the top center of the vertical partition. A pair of scrapers are fixed to a section of the side wall of the rotating shaft inside the collection chamber. The pair of scrapers and the vertical partition divide the collection chamber into two separate collection chambers. A pair of sealing plates are fixed to a section of the side wall of the rotating shaft inside the negative pressure chamber. The pair of sealing plates divide the negative pressure chamber into two separate negative pressure chambers. An air suction mechanism, individually controllable to suction air from the corresponding side collection chamber and negative pressure chamber, is installed inside the installation chamber. Suction pipes are connected to the side walls of both separate collection chambers.

[0007] Preferably, a motor is installed at the bottom of the chamber, and the output end of the motor is fixedly connected to the lower end of the rotating shaft.

[0008] Preferably, the edges of the scraper and the sealing plate are fitted with sealing gaskets, the edges of the scraper and the sealing plate respectively abut against the inner walls of the collection chamber and the negative pressure chamber, and the top of the scraper abuts against the bottom of the filter screen.

[0009] Preferably, the suction mechanism includes an air pump installed on the top of the chamber, the suction end of the air pump extends into the installation chamber and is connected to a distribution pipe, the two ends of the distribution pipe are respectively connected to the negative pressure chambers on both sides, a plunger is installed at the connection between the distribution pipe and the suction end, the plunger is provided with an L-shaped channel connecting the suction end and the distribution pipe on one side, and the upper end of the rotating shaft is fixedly connected to the bottom of the plunger.

[0010] Preferably, cylinders are installed on both sides of the bottom of the chamber, and the telescopic ends of the cylinders extend into the corresponding collection chambers and are fixed with vertical extrusion plates. The extrusion plates are arranged parallel to and cooperate with the vertical partitions.

[0011] Preferably, the bottom of the collecting chamber is provided with a discharge port, and an opening and closing plate is elastically installed inside the discharge port by a spring.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By installing a pair of negative pressure chambers, a pair of collection chambers, a pair of scrapers, a pair of sealing plates, and an air suction mechanism, and starting the air pump, the L-shaped channel inside the plunger connects the suction end to the right air distribution end. The pair of sealing plates, the pair of scrapers, and the vertical partition achieve a sealed separation between the negative pressure chamber and the collection chamber. The negative pressure chamber on the right generates negative pressure, which allows sawdust to be sucked into the right collection chamber through the right suction pipe. Some sawdust is adsorbed on the right half of the filter screen. When cleaning is required, simply start the motor to drive the rotating shaft to rotate, which in turn rotates the pair of sealing plates and the pair of scrapers 180°. The scrapers pass through the filter screen and scrape off the sawdust adsorbed on the right half of the filter screen, which falls into the right collection chamber for collection. At the same time, the rotating shaft drives the plunger to rotate, connecting the L-shaped channel to the left air distribution end and the suction end, allowing for continuous dust collection without stopping the machine for cleaning.

[0014] 2. By installing an extrusion plate, discharge port, and opening / closing plate, when the collection chamber is full of sawdust, simply start the cylinder on the corresponding side to drive the extrusion plate to squeeze the sawdust into dust blocks. Then, open the opening / closing plate on the corresponding side to remove the dust blocks, which is convenient for centralized processing and will not scatter again. Attached Figure Description

[0021] Reference Figure 1-3 A sawdust collection chamber includes a chamber body 1. From top to bottom, the chamber body 1 contains an installation chamber 13, a negative pressure chamber 12, and a collection chamber 11. The installation chamber 13 and the negative pressure chamber 12 are separated by a horizontal partition 15. A filter screen 16 is installed between the negative pressure chamber 12 and the collection chamber 11. A vertical partition 6 is fixedly installed inside the collection chamber 11. A rotating shaft 17, passing through the filter screen 16, is rotatably connected to the top center of the vertical partition 6. A pair of scrapers 18 are fixed to a section of the side wall of the rotating shaft 17 inside the collection chamber 11. The pair of scrapers 18 and the vertical partition 6 divide the collection chamber 11 into two separate collection chambers. A pair of sealing plates 19 are fixed to a section of the side wall of the rotating shaft 17 inside the negative pressure chamber 12. The pair of sealing plates 19 divide the negative pressure chamber 12 into two separate negative pressure chambers. An air suction mechanism, which can be individually controlled to suction air from the corresponding side collection chamber and negative pressure chamber, is installed inside the installation chamber 13. Suction pipes 3 are connected to the side walls of both separate collection chambers 11.

[0022] Furthermore, a motor 9 is installed at the bottom of the chamber 1. The output end of the motor 9 is fixedly connected to the lower end of the rotating shaft 17. When the motor 9 is started, it drives the rotating shaft 17 to rotate, which in turn drives a pair of sealing plates 19 and a pair of scrapers 18 to rotate 180°. The scrapers 18 pass through the filter screen 16, which can scrape off the saw dust adsorbed by the filter screen 16 on the right side and collect it in the right collection chamber. At the same time, the rotating shaft 17 drives the plunger 20 to rotate, so that the L-shaped channel 21 connects the left air distribution end and the air extraction end, which can perform continuous dust collection without stopping the machine for cleaning.

[0023] Furthermore, sealing gaskets are embedded on the edges of the scraper 18 and the sealing plate 19 to achieve sealing. The edges of the scraper 18 and the sealing plate 19 respectively abut against the inner walls of the collection chamber 11 and the negative pressure chamber 12, and the top of the scraper 18 abuts against the bottom of the filter screen 16, which can scrape off the saw dust adsorbed by the filter screen 16.

[0024] Specifically, the suction mechanism includes a suction pump 2 installed on the top of the chamber 1. The suction end of the suction pump 2 extends into the installation chamber 13 and is connected to a distribution pipe 14. Both ends of the distribution pipe 14 are connected to the negative pressure chambers on both sides. A plunger 20 is installed at the connection between the distribution pipe 14 and the suction end. The plunger 20 is provided with an L-shaped channel 21 that connects the suction end and the distribution pipe 14 on one side. The upper end of the rotating shaft 17 is fixedly connected to the bottom of the plunger 20. The rotating shaft 17 drives the plunger 20 to rotate, so that the L-shaped channel 21 connects the left or right distribution end and the suction end.

[0025] Furthermore, cylinders 4 are installed on both sides of the bottom of the hopper 1. The telescopic ends of the cylinders 4 extend into the corresponding collection chambers and are fixed with vertical extrusion plates 5. The extrusion plates 5 are arranged parallel to the vertical partitions 6 and cooperate with them. When the cylinders 4 on the corresponding side are activated, the extrusion plates 5 are driven to extrude saw dust and compress it into dust blocks.

[0026] Furthermore, the bottom of the collection chamber is provided with a discharge port 7, and an opening and closing plate 8 is elastically installed inside the discharge port 7 by a spring 10. By opening the opening and closing plate 8 on the corresponding side, the dust block can be taken out, which is convenient for centralized processing and will not be scattered again.

[0027] When in operation, the vacuum pump 2 is started. At this time, the L-shaped channel 21 in the plunger 20 connects the suction end to the right air distribution end. A pair of sealing plates 19, a pair of scrapers 18, and the vertical partition 6 seal and separate the negative pressure chamber 12 and the collection chamber 11. The negative pressure chamber on the right generates negative pressure, which can suck the saw dust into the right collection chamber through the right suction pipe 3. Some of the saw dust is adsorbed on the right half of the filter screen 16. When cleaning is required, simply start the motor 9 to drive the rotating shaft 17 to rotate, which will drive the pair of sealing plates 19 and the pair of scrapers 18 to rotate 180°. The scraper 18 rotates through the filter screen 16 and can scrape off the saw dust adsorbed on the right half of the filter screen 16, which will fall into the right collection chamber for collection. At the same time, the rotating shaft 17 drives the plunger 20 to rotate, so that the L-shaped channel 21 connects the left air distribution end and the suction end, allowing for continuous vacuuming without stopping the machine for cleaning.

[0028] When the collection chamber is full of saw dust, simply activate the cylinder 4 on the corresponding side to drive the extrusion plate 5 to squeeze the saw dust into dust blocks. Then, open the opening and closing plate 8 on the corresponding side to remove the dust blocks for centralized processing and to prevent secondary scattering.

[0029] 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.
