Description

Technical Field

[0001] The utility model relates to the technical field of decorative panel processing, in particular to a dust removal device for decorative panel processing. Background Technique

[0002] During the processing of decorative panels, a large amount of dust and harmful substances will be generated. These dusts and particles directly harm the respiratory system and skin of workers. Long-term exposure may lead to occupational diseases such as pneumoconiosis. Installing and using a dust collector can effectively filter and reduce these harmful substances. As people pay more and more attention to health, the types of dust removal devices for decorative panel processing are also increasing.

[0003] For example, a Chinese patent (publication number: CN211762208U) discloses a dust removal device for decorative panel processing, which relates to the field of dust removal devices for decorative panel processing. It includes a dust collection box, which is arranged on one side of the processing table. On the other side of the processing table, a blowing box is fixedly welded. One side of the blowing box away from the processing table is communicated with a blower. On the side of the blowing box close to the processing table, there are several groups of equally spaced blowing holes. The bottom of the dust collection box is supported on a support plate, and support legs are fixedly welded at the four corners of the bottom surface of the processing table. In this utility model, a blowing box is arranged on one side of the processing table, and a dust collection box is arranged on the other side. The blowing box can blow the dust and debris generated during the processing on the surface of the processing table into the dust collection box for collection. The collection is convenient and has a good dust removal effect.

[0004] When this utility model removes dust, a blowing box is arranged on one side of the processing table, and a dust collection box is arranged on the other side. When the blower is started, the blowing box can blow out air through several groups of blowing holes to blow the dust and debris generated during the processing on the surface of the processing table into the dust collection box for collection. However, if the dust is near the blowing box, the dust needs to pass through the entire processing table to be collected. If a person is located between the blowing box and the integrated box, they will accidentally inhale the dust, thus endangering their physical health. Moreover, the dust is adsorbed by a cotton dust reduction plate. If the dust is blown up and floats relatively high, it needs to wait for the dust to slowly fall before it can be adsorbed to avoid the dust being raised again. However, dust removal and processing are carried out simultaneously. Therefore, it is inevitable that people will be on the processing table, and the dust blown up relatively high will inevitably endanger the staff. Therefore, a dust removal device for decorative panel processing is proposed to solve the above problems. Summary of the Utility Model

Detailed Embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 2 , a dust removal device for veneer processing in this embodiment, includes a processing table 1. Table legs 2 are fixedly arranged at the bottom of the processing table 1 and located at the four corners. A dust suction assembly 3 for sucking away processing dust is arranged at the bottom of the processing table 1. A telescopic control mechanism 4 for controlling the dust suction distance is arranged inside the four table legs 2.

[0024] In addition, the dust suction assembly 3 includes two suction heads 301 in contact with the top of the processing table 1. Dust suction pipes 302 are fixedly communicated with the opposite sides of the two suction heads 301 respectively. Bellows 303 penetrating into the four table legs 2 are fixedly communicated with the bottoms of the two dust suction pipes 302 respectively. A funnel 304 is fixedly arranged at the bottom of the processing table 1. The opposite sides of the two bellows 303 are fixedly communicated with the funnel 304. An air inlet pipe 305 is fixedly communicated with the bottom of the bellows 303 on the left side. A self - suction structure 306 is arranged at the bottom of the air inlet pipe 305. An air outlet pipe 307 is fixedly communicated with the bottom of the self - suction structure 306. A dust collection bucket 308 is clamped at the bottom of the air outlet pipe 307. Moving plates 309 are fixedly arranged at the bottoms of the two dust suction pipes 302.

[0025] It can be known that the two suction heads 301 are respectively located on the left and right sides of the top surface of the processing table 1. The dust suction pipe 302 is L - shaped, and the air outlet pipe 307 is Z - shaped. The Z - shaped air outlet pipe 307 can make the dust collection bucket 308 located behind the telescopic control mechanism 4, so as to vacate a position for the telescopic control mechanism 4 and enable the dust removal device to operate smoothly.

[0026] In addition, the self - suction structure 306 includes a rotating rod, and eight fan blades are fixedly arranged on the outer surface of the rotating rod. The self - suction structure 306 further includes a housing. The right side of the rotating rod penetrates through the housing and is rotatably connected with the housing. The top and bottom of the housing are fixedly communicated with the air inlet pipe 305 and the air outlet pipe 307 respectively. By the rotation of the eight fan blades, a pressure difference appears between the air inlet pipe 305 and the air outlet pipe 307, so as to promote the air in the air inlet pipe 305 to continuously flow into the air outlet pipe 307 to realize air suction.

[0027] It should be further noted that a plurality of dust suction holes are provided on the processing table 1 above the funnel 304. The plurality of dust suction holes are arranged in a multi-layered circular pattern. The diameter of the ring at the top of the funnel 304 is equal to the diameter of the outermost circular layer of the dust suction holes. The bottom of the moving plate 309 is rotatably connected with rollers. Threaded holes with opposite helix directions are provided inside both moving plates 309. Setting them to be equal can make the funnel 304 fully adapted to the dust suction holes and prevent dust from overflowing.

[0028] In this embodiment, through the cooperation of the two suction heads 301 and the dust suction holes, dust can be sucked simultaneously in three directions, removing dust in the shortest time and preventing dust from floating randomly, thereby protecting the health of the staff.

[0029] Please refer to Figures 3 to 4 , in order to ensure both the dust removal efficiency and the dust removal effect at the same time, the telescopic control mechanism 4 in this embodiment includes a servo motor 401 fixed to the four table legs 2 and a driven rod 403 passing through both moving plates 309 and threadedly connected to them. Threaded strips are fixed to the left and right ends of the outer surface of the driven rod 403. The threaded strips are adapted to the threaded holes. The output shaft of the servo motor 401 is fixed with a driving rod 402. The driving rod 402 is fixed to the rotating rod. Driving wheels 404 and driven wheels 405 are respectively fixed to the outer surfaces of the driving rod 402 and the driven rod 403. The outer surfaces of the driving wheel 404 and the driven wheel 405 are both drivingly connected with a conveyor belt 406. A control part 407 is provided on the front surface of the conveyor belt 406.

[0030] It should be particularly noted that the control part 407 includes a base 4071 and a stop block 4076 fixed between the two front table legs 2. A spring 4072 is fixed to the top of the base 4071. A pedal 4073 is fixed to the top of the spring 4072. The rear end of the pedal 4073 is hinged with a connecting rod 4074 located in front of the stop block 4076. The top of the connecting rod 4074 is hinged with a swing rod 4075 located behind the stop block 4076. The connecting rod 4074 and the swing rod 4075 are suspended by the stop block 4076. A pulley 4077 is movably connected to the end of the swing rod 4075 away from the connecting rod 4074. Through the cooperation of the stop block 4076 and the pedal 4073, the swing rod 4075 can be prompted to tilt up, thereby controlling the transmission of power.

[0031] In addition, the front end of the pedal 4073 is hinged to the base 4071. A pressing block is fixed to the top of the base 4071. Fixed frames are fixed to all four table legs 2. The servo motor 401 is fixed to the four table legs 2 through the fixed frames. When the pedal 4073 is stepped on, due to the action of the pressing block, a force feedback will be given to inform the staff that the pedal 4073 has been stepped on to the appropriate position.

[0032] In this embodiment, when adjustment is needed, step on the pedal 4073. Under the action of the stop block 4076, the swing rod 4075 is urged to tilt up, so that the swing rod 4075 tilts up smoothly, and then the pulley 4077 jacks up the conveyor belt 406, causing the conveyor belt 406 to be tensioned to achieve power transmission.

[0033] It should be noted that after the servo motor 401 is started, the dust collection component 3 starts continuous dust collection. Continuous dust collection in three directions can ensure the dust collection efficiency and effect. When the suction head 301 needs to be adjusted during the processing, the pedal 4073 can be stepped on at any time, so as to transmit the power of the servo motor 401 to the driven rod 403, thereby adjusting the relative position of the suction head 301.

[0034] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect the mechanical device, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0035] The working principle of the above embodiment is as follows:

[0036] (1) After the staff puts the decorative panel to be processed on the processing table 1, start the servo motor 401. The power of the servo motor 401 is transmitted to the fan blade on the self-suction structure 306 through the driving rod 402, so that the dust is sucked into the self-suction structure 306 from the suction head 301 through the dust suction pipe 302, the corrugated pipe 303 and the air inlet pipe 305. Then the self-suction structure 306 sends the dust to the dust collection bucket 308 through the air outlet pipe 307 for collection. At the same time, the dust suction holes will also suck in the dust that may float out, and the dust is sucked into the self-suction structure 306 through the funnel 304, the corrugated pipe 303 and the air inlet pipe 305, and the self-suction structure 306 sends the dust to the dust collection bucket 308 through the air outlet pipe 307.

[0037] (2) During the processing, the pedal 4073 can be stepped on at any time. The pedal 4073 will pull down the connecting rod 4074. Since the connecting rod 4074 is hinged to the swing rod 4075 and is simultaneously suspended on the stop block 4076, at this time, the end of the swing rod 4075 far from the connecting rod 4074 will be lifted, so that the pulley 4077 will tension the conveyor belt 406. Further, the power of the servo motor 401 is transmitted from the driving wheel 404 to the driven rod 403 through the conveyor belt 406. Since the driven rod 403 is threadedly connected to the two moving plates 309, and the bottoms of the two moving plates 309 are rotatably connected with rollers, the rotation of the driven wheel 405 is converted into the translation of the two moving plates 309, thus realizing the function of adjustable distance between the two suction heads 301. This structure has good dust removal effect. At the same time, due to dust suction in three directions, the dust can be sucked away in the shortest time, avoiding the harm of dust floating around to human health. At the same time, the suction head 301 can be adjusted at any time during the processing, which can not only ensure the processing efficiency and dust removal efficiency, but also take into account the dust removal quality.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
