Description

Technical Field

[0001] The invention relates to the field of furniture processing and cutting equipment, in particular to a furniture processing positioning and cutting device. Background Art

[0002] As the furniture manufacturing industry is booming, consumers' expectations for furniture quality are rising, making furniture processing technology in urgent need of innovation.

[0003] In the past, manual handheld cutting tools were the mainstream operation method. Workers only relied on experience and simple measuring tools such as tape measures and squares to manually cut. The efficiency was extremely low, and the amount of cutting a skilled worker could do in a day was also quite limited. In addition, the cutting accuracy was not guaranteed, dimensional deviations occurred frequently, and subsequent assembly was difficult, and a large amount of raw materials and labor costs were wasted.

[0004] In the early days of mechanization, simple mechanical cutting equipment appeared, but most of them only had a single rotary cutting function. The cutting blade was fixed on the rotating shaft and driven by a motor to rotate at high speed. Faced with plates of various materials, due to their different hardness and texture, the fixed cutting mode had high resistance, the blade wore quickly, and the replacement of the blade caused frequent downtime; at the same time, the plate cuts were prone to roughness and edge collapse, affecting the appearance, and subsequent grinding and finishing consumed manpower.

[0005] Moreover, traditional equipment is not accurate in positioning, and workers need to repeatedly measure and adjust the plate during operation, which is a cumbersome process and prone to errors. A large amount of debris generated by cutting splashes everywhere, polluting the environment and endangering the health of workers, and cleaning is time-consuming and laborious.

[0006] There are even more hidden dangers in terms of safety. Early equipment lacked protection and emergency braking measures. If workers were not careful and got close to the high-speed rotating blades, it would easily cause serious work-related accidents, threatening their lives and causing a double blow to the company's economy and reputation.

Specific embodiments

[0023] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides a furniture processing positioning and cutting device, as Figure 1As shown in the figure, it includes a processing table 1. The processing table 1 serves as the basic bearing component of the entire device, providing a stable platform for the installation of subsequent components. There is a first opening 2 on its upper surface. The setting of the first opening 2 reserves space for the operation of the cutting component below, enabling the cutting operation to proceed smoothly. At the position near the first opening 2 at the bottom end of the processing table 1, a housing 3 is movably installed. Inside the housing 3, there are many key transmission and drive components. Its material is strong and durable, effectively protecting the internal parts. There is a second opening 4 on the upper surface of the housing 3. The second opening 4 cooperates with the first opening 2 of the processing table 1 to ensure that the cutting blade 6 can smoothly cut the plate during operation without being hindered. A first rotating shaft 5 is movably installed inside the housing 3. The first rotating shaft 5 is the direct carrier of the cutting blade 6, and the stability of its rotation is directly related to the cutting effect. A cutting blade 6 is fixedly installed on its outer diameter. The cutting blade 6 is made of high-quality alloy steel, which is sharp and wear-resistant, and can efficiently perform cutting operations on various furniture plates.

[0025] In this embodiment, a horizontally arranged second rotating shaft 7 is movably installed at the inner bottom of the housing 3. The second rotating shaft 7 not only shoulders the important task of transmitting power, but also the driving bevel gear 9 fixedly installed on one side of it is a key link to start a series of complex transmissions. The third rotating shaft 8 is vertically arranged on one side of the inner bottom of the housing 3. A driven bevel gear 10 is fixedly installed on the outer diameter of one side of the third rotating shaft 8, and the inner ends of the driven bevel gear 10 and the driving bevel gear 9 are meshed and connected. This precise meshing design ensures the stable and efficient transmission of power from the second rotating shaft 7 to the third rotating shaft 8, providing a solid power foundation for the subsequent high-speed rotation of the cutting blade 6.

[0026] Furthermore, the end of the third rotating shaft 8 extends to the outside of the housing 3 and is fixedly connected to a driving wheel 11. The driving wheel 11 is an important node for power output. It is connected to a driven wheel 12 fixedly connected to the end of the first rotating shaft 5 extending to the outside of the housing 3 through a synchronous belt 13. The synchronous belt 13 has good flexibility and transmission efficiency, and can reduce the vibration and wear caused by rigid connection while ensuring stable power transmission, thereby ensuring that the first rotating shaft 5 drives the cutting blade 6 to rotate at high speed and smoothly.

[0027] Furthermore, a three-phase asynchronous motor 14 is fixedly installed on one side of the bottom of the shell 3. The three-phase asynchronous motor 14 is the core power source of the entire device. It has strong power and stable operation, providing a continuous source of power for the continuous operation of the device. The driving end of the three-phase asynchronous motor 14 extends to the interior of the shell 3 and is fixedly installed with a driving gear 15. The driving gear 15 cooperates with a driven gear 17 movably installed on the outer diameter of one side of the second rotating shaft 7. The driven gear 17 is closely linked with the second rotating shaft 7 under the ingenious design of the card slot 19 and the card block 20. Specifically, a compression spring 16 is fixedly connected to the outer diameter of the second rotating shaft 7 at a position close to the compression spring 16. The compression spring 16 is selected It is made of high-strength elastic material, and its end abuts against one end of the driven gear 17, providing a moderate clamping force for the driven gear 17 to ensure the stability of the transmission. A fixed plate 18 is fixedly connected to the other side of the outer diameter of the second rotating shaft 7 close to the driven gear 17. A plurality of slots 19 are provided on the side of the fixed plate 18 close to the driven gear 17. A plurality of blocks 20 are fixedly connected to the side of the driven gear 17 close to the fixed plate 18, and the ends of the blocks 20 are precisely arranged inside the corresponding side slots 19. The limiting structure of the slots 19 and the blocks 20 enables the driven gear 17 to accurately drive the second rotating shaft 7 to rotate synchronously when rotating, avoiding the problem of poor power transmission such as slipping.

[0028] Furthermore, a short shaft 22 is movably installed on one side of the inner part of the shell 3, and the inner end of the short shaft 22 extends to the inside of the shell 3 and is fixedly connected to a worm wheel 23. The bottom of the worm wheel 23 is meshed and connected to the middle of the worm 21, and the worm 21 is fixedly connected to the middle outer diameter of the third rotating shaft 8. When the third rotating shaft 8 rotates, the meshing transmission of the worm 21 and the worm wheel 23 drives the short shaft 22 to rotate, thereby realizing diversified power transmission. The outer end of the short shaft 22 extends to the outside of the shell 3 and is fixedly connected to a first chuck 24. The bottom end of the processing table 1 is fixedly connected to a fixing frame 25 near the two sides of the shell 3, and the bottom of the fixing frame 25 on one side is fixedly connected to a second chuck 26 The inner ends of the second chuck 26 and the first chuck 24 are fixedly connected with a plurality of hemispherical protrusions 27, and the positions of the hemispherical protrusions 27 are staggered to form a unique tooth structure. The bottom end of the fixing frame 25 on the other side is fixedly connected with a reset spring 28. The reset spring 28 is made of a highly elastic alloy material, and its end is fixedly connected to one end of the shell 3. When the short shaft 22 drives the first chuck 24 to rotate, the tooth structure formed by the hemispherical protrusions 27 staggered with the second chuck 26, in conjunction with the elastic expansion and contraction effect of the reset spring 28, drives the shell 3 to vibrate rapidly back and forth, thereby driving the cutting blade 6 to vibrate back and forth, greatly improving the cutting effect.

[0029] Further, a backrest 35 is movably installed on one side of the upper surface of the processing table 1. The backrest 35 provides a reliable positioning reference for the plate to be cut, ensuring that the plate always remains vertical during the cutting process, guaranteeing the cutting accuracy. A telescopic cylinder 36 is fixedly installed on the upper surface of the processing table 1 near the backrest 35. The driving end of the telescopic cylinder 36 is fixedly connected to the middle of the backrest 35. Through the precise telescopic control of the telescopic cylinder 36, the backrest 35 can be accurately driven to move, thereby driving the plate to move, so that the cutting position of the plate coincides precisely with the laser line, providing an accurate reference for cutting and effectively improving the cutting accuracy.

[0030] Further, a collection chamber 38 is fixedly installed at the rear side of the upper surface of the processing table 1. The collection chamber 38 serves as a storage place for cutting debris. Its internal space is reasonably designed and can accommodate a large amount of debris. A conveying pipe 39 is fixedly installed on one side of the collection chamber 38. The end of the conveying pipe 39 extends above the telescopic cylinder 36 and precisely aligns with the cutting area to ensure that the debris generated during cutting can be promptly sucked in. A negative pressure fan 40 is fixedly installed above the collection chamber 38. After the negative pressure fan 40 is started, the collection chamber 38 can be quickly evacuated to a vacuum state. The strong pressure generates a strong suction force in the conveying pipe 39, efficiently sucking the debris generated during cutting into the collection chamber 38, facilitating later cleaning and keeping the working environment clean.

[0031] Furthermore, the protective cover 37 is disposed above the upper surface of the processing table 1 near the first opening 2. The protective cover 37 is made of high-strength transparent plastic material, which can effectively block the flying debris generated during cutting, protect the personal safety of the operator, and does not prevent the operator from observing the cutting process. A laser pen 41 is fixedly installed at the top of the protective cover 37 and is inclined. The high-brightness light emitted by the laser pen 41 can form a straight light ray that precisely falls on the surface of the plate through the refraction of the cylindrical lens 42 fixedly installed on one side of the top of the protective cover 37 near the laser pen 41, providing a clear indication for the cutting position. A thermal infrared instrument 43 is fixedly installed on one side of the bottom end of the protective cover 37. The thermal infrared instrument 43 has a high-sensitivity thermal imaging sensing ability and can monitor the temperature change around the cutting area in real time. When the hand of the operator approaches the cutting blade 6, the thermal infrared instrument 43 will quickly sense the thermal imaging of the human body, and then quickly start the igniter 34 through the action of the sensor. The igniter 34 is installed on one side of the top of the braking chamber 29. The braking chamber 29 is fixedly connected to the middle part inside the housing 3. The inside of the braking chamber 29 is filled with a mixed gas 33, which is carefully proportioned by atomized gasoline and air. At the moment when the igniter 34 ignites the mixed gas 33 in the braking chamber 29, a strong pressure will be generated inside the braking chamber 29, and the piston 30 and the piston rod braking rod 31 will be pushed to move, so that the braking disc 32 at the end of the braking rod 31 quickly and precisely abuts against one side of the cutting blade 6, achieving an emergency braking effect on the cutting blade 6, avoiding personal injury caused by misoperation, and greatly improving the safety of the device during use. Support legs 44 are fixedly connected to the four corners of the bottom end of the processing table 1. The support legs 44 are made of strong metal material and have good load-bearing capacity and stability, ensuring that the entire device is stable and reliable during operation and will not have problems such as shaking and displacement.

[0032] Working principle: Place the furniture board to be cut on the processing table 1, with one end of the board abutted against one end of the backing board 35 to keep the board in a vertical state. Then turn on the laser pen 41. The light emitted by the laser pen 41 forms a straight light ray on the surface of the board through the refraction of the cylindrical lens 42. Then start the telescopic cylinder 36. Drive the backing board 35 to move through the telescopic cylinder 36, drive the board to move, and make the cutting position of the board coincide with the laser line, providing a reference for subsequent cutting and improving cutting accuracy. Then turn on the three-phase asynchronous motor 14. Drive the driving gear 15 to rotate through the three-phase asynchronous motor 14. The driving gear 15 drives the driven gear 17 to rotate through meshing transmission. Utilize the limiting effect of the card slot 19 and the block 20 to drive the second rotating shaft 7 to rotate. The rotating second rotating shaft 7 drives the driving bevel gear 9 at the end to rotate. When the driving bevel gear 9 rotates, it will drive the driven bevel gear 10 and the third rotating shaft 8 to rotate. When the third rotating shaft 8 rotates, it will drive the driving wheel 11 at the end to rotate. Utilize the transmission of the synchronous belt 13 to drive the driven wheel 12 and the first rotating shaft 5 to rotate, thereby driving the cutting blade 6 to rotate at high speed. Then the staff pushes the board forward slowly, and uses the cutting blade 6 rotating at high speed to realize the cutting work of the board. In addition, when the third rotating shaft 8 rotates, it will also drive the worm 21 in the middle to rotate. The rotating worm 21 drives the worm gear 23 and the short shaft 22 to rotate through meshing transmission, thereby driving the first chuck 24 to rotate. Utilize the toothed structure formed by the hemispherical protrusions 27 staggered between the first chuck 24 and the second chuck 26, and cooperate with the action of the return spring 28 to drive the housing 3 to vibrate back and forth rapidly, thereby driving the cutting blade 6 to vibrate back and forth. The cutting blade 6 rotating at high speed combined with the reciprocating vibration effect can not only reduce the cutting resistance and reduce the influence of debris generated during cutting, but also polish the cut, improving the quality of the board after cutting. The debris generated during the cutting of the board will be blocked and intercepted by the protective cover 37. At this time, turn on the negative pressure fan 40. The negative pressure fan 40 instantly evacuates the collection chamber 38 to a vacuum state. The strong pressure generates a strong suction force in the conveying pipeline 39, sucking the debris generated by cutting into the collection chamber 38 for convenient later cleaning. When the staff's hand approaches the cutting blade 6, the thermal infrared detector 43 will sense the thermal imaging of the human body, and then quickly start the igniter 34 through the sensor. The igniter 34 ignites the mixed gas 33 in the braking chamber 29. The mixed gas is composed of atomized gasoline and air. At the moment of ignition, a strong pressure will be generated inside the braking chamber 29, and push the piston 30 and the piston rod braking rod 31 to move, so that the braking disc 32 at the end of the braking rod 31 abuts against one side of the cutting blade 6, realizing the emergency braking effect on the cutting blade 6 and improving the use safety. At the same time, when the cutting blade 6 stops rotating, it will drive the first rotating shaft 5, the driving wheel 11, the driven wheel 12 and the second rotating shaft 7 to stop rotating together. At this time, the main shaft of the three-phase asynchronous motor 14 and the driving gear 15 are still rotating, so that the rotating driven gear 17 will compress the compression spring 16,Moreover, the latch 20 and the slot 19 will continuously disengage and engage, and at this time, the driven gear 17 will no longer apply a rotational force to the second rotating shaft 7, which can play a role in protecting the three-phase asynchronous motor 14.
