Safety guard planer based on furniture production

Abstract

This invention discloses a safety-protected planer for furniture production, relating to the field of wood processing technology. This safety-protected planer for furniture production, through the cooperation of a drive belt and a side drive frame, can limit the movement of the wood plank during operation and simultaneously drive the plank into the machine body until surface finishing is completed. Compared to traditional processing methods, it eliminates the need for manual adjustment of the plank's orientation. Furthermore, the cooperation of a baffle plate and an elastic end plate increases the friction between the drive belt and the plank, ensuring effective pushing of the plank. Additionally, the extension of the baffle plate and the deformation of the elastic end plate during operation achieve material blocking and pushing effects, further enhancing the operational safety of the equipment.

Description

Technical Field

[0001] This invention relates to the field of wood processing technology, specifically a safety-protected planer for furniture production. Background Technology

[0002] When processing wood or similar materials, the planer is the core finishing equipment. The planer relies on the high-speed rotating planer blade to cut the wood, which can quickly repair the surface of the board, correct flatness and thickness errors, remove burrs and hard knots, improve the regularity of the workpiece, and facilitate subsequent processes such as cutting, splicing, and painting. Referring to the Chinese patent, "A dust-free wood planer for woodworking and its method of use" with publication number "CN111531648B", this patent points out that existing wood planers are all designed for processing functions. During actual use, wood chips will be discharged from the chip discharge groove, which can easily affect the surrounding environment. When the above-mentioned equipment processes wood boards, although it pushes the wood boards through auxiliary transmission rollers, the direction of the wood boards still needs to be manually adjusted during processing, which affects the safety of operation. Secondly, although the equipment uses a vacuum pump to extract and collect wood chips, the high-speed planer still causes some wood chips to fly out during operation, which reduces the safety of operation. In response, we propose a safety protection planer based on furniture production to solve the above problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a safety-protected planer for furniture production, solving the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a safety protective planer based on furniture production, comprising a machine body, a protective cover fixedly installed on the top of the machine body, a drive belt rotatably connected inside the protective cover, a wooden board body being conveyed below the drive belt, and a cutting tool assembly assembled in the middle of the machine body; Both sides of the drive belt are rotatably mounted with drive shafts. The ends of the two drive shafts are fitted with telescopic plates between the ends of the two drive shafts and the top of the inner side of the protective cover. The protective cover is fixedly installed with a drive cylinder. The piston end of the drive cylinder is fixedly mounted with a lower pressure frame. The lower pressure frame is fixedly connected to the ends of multiple telescopic plates, which is used to drive the two drive shafts and the drive belt to move downward as a whole. Two drive chains are rotatably mounted between two drive shafts. The two drive chains are located on both sides of the drive belt, and multiple baffles are assembled between the two drive chains. A rotating shaft is fixedly mounted on one end of the baffle, and the rotating shaft is rotatably connected to the drive chain. A torsion spring is sleeved on the end of the rotating shaft. Multiple elastic end plates are fixedly mounted on the end of the baffle away from the rotating shaft. Multiple rectangular slots are opened on the outer surface of the drive belt for storing the baffles.

[0006] Preferably, a drive motor is fixedly installed on the top of the lower pressure frame, and a transmission chain connects the drive motor to the corresponding drive shaft.

[0007] Preferably, side drive frames are slidably mounted on both sides of the inner side of the machine body. The side drive frames on both sides are used to simultaneously move inward to contact the bottom side of the wooden board body, pushing the wooden board body to the center position inside the machine body.

[0008] Preferably, the interior of the machine body is symmetrically provided with multiple limiting slide grooves, the bottom of the side drive frame is fixedly installed with multiple slide rods, the slide rods are slidably connected in the corresponding limiting slide grooves, the ends of the slide rods are fixedly installed with drive gear plates, and the bottom of the machine body is rotatably connected with multiple drive gears, the drive gears and the drive gear plates on both sides are always engaged.

[0009] Preferably, the inner sides of the side drive frames on both sides are rotatably connected to multiple cylindrical members.

[0010] Preferably, the tool assembly is slidably mounted on the inner middle of the machine body, and a tool holder is rotatably connected to the top of the tool assembly. Multiple blade bodies are fixedly mounted on the outer side of the tool holder.

[0011] Preferably, a limit frame is fixedly installed on the side of the tool assembly, and an arc-shaped slide is slidably connected inside the limit frame. The arc-shaped slide is located on the outside of multiple blade bodies, and a return spring is fixedly installed between the arc-shaped slide and the limit frame.

[0012] Preferably, the ends of the arc-shaped carriage are rotatably connected to multiple end rollers.

[0013] Preferably, a feed rack is fixedly mounted on the outside of the tool assembly.

[0014] This invention provides a safety-protected planer for furniture production. Compared with existing technologies, it has the following advantages: (1) This safety protection planer based on furniture production can limit the position of the wooden board body during operation by cooperating with the drive belt and the side drive frame, and at the same time drive the wooden board body to be transported into the machine body in the center until the surface is finished. Compared with the traditional processing method, there is no need to manually assist the wooden board to adjust the direction. At the same time, through the cooperation of the baffle plate and the elastic end plate, on the one hand, the friction between the drive belt and the wooden board body can be increased to ensure the pushing effect of the wooden board body. On the other hand, during operation, the extension of the baffle plate and the deformation of the elastic end plate can achieve the effect of blocking and pushing the material, further improving the operation safety of the equipment.

[0015] (2) The safety protection planer based on furniture production, through the cooperation of the arc-shaped slide and the limit frame, when the moving wooden board body comes into contact with the arc-shaped slide, it can drive the arc-shaped slide to slide along the limit frame, so that it retracts into the limit frame until the wooden board body separates from the arc-shaped slide. The arc-shaped slide is reset again through the cooperation of the return spring, which improves the protection effect and safety of the blade body, while avoiding damage caused by the contact between the elastic end plate and the running blade body.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments: Example

[0020] In this embodiment of the invention, a safety protective planer based on furniture production includes a machine body 1, a protective cover 2 fixedly installed on the top of the machine body 1, a viewing window 201 installed on one side of the protective cover 2, the viewing window 201 being made of tempered glass to facilitate observation of the processing of the wooden board body 7, a drive belt 8 being rotatably connected inside the protective cover 2, the wooden board body 7 being conveyed below the drive belt 8, and a tool assembly 3 being assembled in the middle of the machine body 1. During operation, the wooden board body 7 is placed on the machine body 1 and positioned below the drive belt 8. At this time, the drive belt 8 moves down to contact the wooden board body 7 and runs, pressing the wooden board body 7 and conveying it towards the tool assembly 3. The running tool assembly 3 completes the processing operation on the wooden board body 7. In this embodiment of the invention, drive shafts 9 are rotatably mounted on both sides of the inner side of the drive belt 8. Telescopic plates 10 are assembled between the ends of the two drive shafts 9 and the top inner side of the protective cover 2. A drive cylinder 11 is fixedly installed inside the protective cover 2. A lower pressure frame 12 is fixedly installed on the piston end of the drive cylinder 11. The lower pressure frame 12 is fixedly connected to the ends of the multiple telescopic plates 10, and is used to drive the two drive shafts 9 and the drive belt 8 to move downward as a whole. Specifically, the lower pressure frame 12 is I-shaped, with its four ends fixed to the ends of the telescopic plate frames 10 around it. As the drive cylinder 11 extends, the lower pressure frame 12 can drive multiple telescopic plate frames 10 to extend simultaneously, so that the drive shafts 9 on both sides can move downward as the telescopic plate frames 10 extend, thereby driving the drive belt 8 to move downward as a whole through the drive shafts 9, so that the drive belt 8 contacts the top of the wooden board body 7. Specifically, both ends of the drive shaft 9 pass through the corresponding ends of the telescopic frame 10 and maintain a rotatable connection with the ends of the telescopic frame 10. In this embodiment of the invention, two drive chains 901 are rotatably installed between two drive shafts 9. The drive chains 901 cooperate with existing sprockets, which are fixedly sleeved on the ends of the drive shafts 9. The two drive chains 901 are located on both sides of the drive belt 8, and the drive chains 901 on both sides are connected to the two sides of the drive belt 8 by steel wire ropes to ensure the driving effect of the drive belt 8 on the wooden board body 7 and to prevent slippage due to excessive force when the drive belt 8 contacts the wooden board body 7. Multiple baffle plates 14 are assembled between the two drive chains 901. A rotating shaft is fixedly installed at one end of the baffle plate 14. The rotating shaft is rotatably connected to the drive chain 901, and a torsion spring is sleeved at the end of the rotating shaft. Multiple elastic end plates 1401 are fixedly installed at the end of the baffle plate 14 away from the rotating shaft. Multiple rectangular slots 801 are opened on the outer surface of the drive belt 8 for storing the baffle plates 14.

[0021] Specifically, the rotating shaft and torsion spring are existing devices and are not shown in the figure. (Refer to...) Figure 4 The initial position of the baffle plate 14 is at an angle of 45° with the drive belt 8. When the baffle plate 14 moves to below the drive belt 8 along with the drive chain 901, the elastic end plate 1401 at the end of the baffle plate 14 contacts the top of the wooden board body 7. The elastic end plate 1401 deforms under force and drives the baffle plate 14 to rotate along the axis until the baffle plate 14 and the elastic end plate 1401 retract into the corresponding rectangular slot 801. When the elastic end plate 1401 above the wooden board body 7 contacts its top surface, it can deform under force. The elastic end plates 1401 on both sides of the wooden board body 7 can always remain extended until the baffle plate 14 approaches the top surface of the drive belt 801. After the end near the rotating shaft enters between the wooden board body 7 and the drive belt 8, the baffle plate 14 and the elastic end plate 1401 are completely retracted into the rectangular slot 801. By setting the baffle plate 14 and the elastic end plate 1401, the splashed wood chips can be blocked during operation, achieving the effect of material blocking and further improving the operation safety of the equipment. At the same time, by setting the baffle plate 14 and the elastic end plate 1401, the wood chips on the top of the machine body 1 can be pushed from the feed port to the middle of the machine body 1 as the two extend until they fall through the knife slot. The wood chips near the discharge port can be pushed to the discharge port side to avoid wood chips remaining inside the machine body 1, achieving the effect of pushing materials. Specifically, when the baffle plate 14 and the elastic end plate 1401 are retracted into the corresponding rectangular slot 801, their outer sides will still slightly extend beyond the surface of the drive belt 8 to increase the friction between the drive belt 8 and the wooden board body 7, ensuring the pushing effect on the wooden board body 7. Specifically, the elastic end plate 1401 is made of rubber, which will not be described in detail here; Specifically, during the above operation, when the thickness of the wooden board body 7 exceeds the length of the elastic end plate 1401, the elastic end plate 1401 will have a certain gap with the top surface of the machine body 1 during the translation process. Although it can still achieve a certain effect of blocking wood chips, when pushing out wood chips, the height of the drive belt 8 needs to be readjusted after the wooden board body 7 is output. This will not be elaborated here. For details, please refer to Figure 1 , Figure 2 The side of the machine body 1 closest to the side drive frame 15 is the feed port, and the side of the machine body 1 away from the side drive frame 15 is the discharge port. The assembly position of the tool assembly 3 in the middle of the machine body 1 is the tool groove. Specifically, through the cooperation of the drive belt 8 and the side drive frame 15, the wooden board body 7 can be limited during operation, and at the same time, the wooden board body 7 is driven to be conveyed into the machine body 1 in the center until the surface is finished. Compared with the traditional processing method, there is no need to manually assist the wooden board body 7 in adjusting its direction. At the same time, through the cooperation of the baffle plate 14 and the elastic end plate 1401, on the one hand, the friction between the drive belt 8 and the wooden board body 7 can be increased to ensure the pushing effect of the wooden board body 7. On the other hand, during operation, the extension of the baffle plate 14 and the deformation of the elastic end plate 1401 can achieve the effect of blocking and pushing materials, further improving the operational safety of the equipment. In this embodiment of the invention, multiple auxiliary pressure frames 13 are fixedly installed on both sides of the lower pressure frame 12, and an auxiliary roller shaft 1301 is rotatably connected between two corresponding auxiliary pressure frames 13. The multiple auxiliary roller shafts 1301 are all located inside the drive belt 8.

[0022] Specifically, the auxiliary pressure frame 13 and the auxiliary roller 1301 are assembled directly above the tool assembly 3 to ensure the driving force of the drive belt 8 on the wooden board body 7. Specifically, a drive motor 1201 is fixedly installed on the top of the lower pressure frame 12. A transmission chain connects the drive motor 1201 to the corresponding drive shaft 9. The drive motor 1201 is an existing device, and the drive shaft 9 is driven by the cooperation of the transmission chain and the sprocket.

[0023] In this embodiment of the invention, side drive frames 15 are slidably mounted on both sides of the interior of the machine body 1. The side drive frames 15 on both sides are used to simultaneously move inward to contact the bottom side of the wooden board body 7, pushing the wooden board body 7 to the center position inside the machine body 1. After the wooden board body 7 is placed on top of the machine body 1, it first moves closer to the wooden board body 7 through the side drive frames 15 on both sides, pushing the wooden board body 7 to the center of the top surface of the machine body 1, while ensuring that the wooden board body 7 remains centered during processing.

[0024] In this embodiment of the invention, the body 1 has multiple symmetrically arranged limiting grooves 1502 inside, and multiple sliding rods 1501 are fixedly installed at the bottom of the side drive frame 15. The sliding rods 1501 are slidably connected inside the corresponding limiting grooves 1502, and drive gear plates 16 are fixedly installed at the ends of the sliding rods 1501. Multiple drive gears 17 are rotatably connected to the bottom of the body 1, and the drive gears 17 are always meshed with the drive gear plates 16 on both sides. (Reference) Figure 6 Both sides of the drive gear 17 are driven by independent forward and reverse motors. The forward and reverse motors are mounted on the lower part of the machine body 1 and are not shown in the figure. As the drive source drives the drive gear 17 on both sides to rotate simultaneously, the side drive frames 15 on both sides can be driven to move inward or outward simultaneously through the cooperation of the drive tooth plate 16 and the slide rod 1501, so as to push the wooden board body 7 of different sizes, thereby realizing the side limit operation of the wooden board body 7.

[0025] In this embodiment of the invention, multiple columnar members 1503 are rotatably connected to the inner sides of the side drive frames 15 on both sides. When the side drive frames 15 approach the wooden board body 7, the columnar members 1503 will first contact the side of the wooden board body 7. During the translation of the wooden board body 7, the columnar members 1503 can be driven to rotate inside the side drive frames 15, ensuring the guiding effect on the wooden board body 7 while reducing the friction on the side of the wooden board body 7. In this embodiment of the invention, the side drive frame 15 moves horizontally close to the top surface of the machine body 1. Therefore, when it comes into contact with the wooden board body 7, it will come into contact with the bottom side of the wooden board body 7. This avoids the drive belt 8 coming into contact with the top of the side drive frame 15 when it moves down, which would reduce the driving force. Therefore, the thickness of the wooden board body 7 needs to exceed the height of the side drive frame 15 during operation.

[0026] Specifically, the tool assembly 3 is slidably mounted on the inner middle of the machine body 1. The top of the tool assembly 3 is rotatably connected to the tool holder 301. Multiple blade bodies 302 are fixedly mounted on the outer side of the tool holder 301. The tool assembly 3 is an existing device, and the mounting height can be adjusted by a hydraulic cylinder, thereby adjusting the processing depth through the blade bodies 302. The blade bodies 302 can also be replaced according to the processing type of the wooden board body 7. The blade bodies 302 and the tool holder 301 are assembled using the existing tool assembly method. The tool holder 301 is driven by an independent motor, which will not be described in detail here.

[0027] Example 2: Based on Example 1, a limit frame 4 is fixedly installed on the side of the tool assembly 3. An arc-shaped slide 5 is slidably connected inside the limit frame 4. The arc-shaped slide 5 is located on the outside of multiple blade bodies 302. A return spring 401 is fixedly installed between the arc-shaped slide 5 and the limit frame 4. Multiple end rollers 501 are rotatably connected to the end of the arc-shaped slide 5.

[0028] Specifically, through the cooperation of the limiting bracket 4 and the arc-shaped slide 5, refer to Figure 7 The initial position of the arc-shaped slide 5 is located above the side of multiple blade bodies 302, which can protect the blade bodies 302. When the moving wooden board body 7 comes into contact with the arc-shaped slide 5, it can drive the arc-shaped slide 5 to slide along the limit frame 4 and retract it into the limit frame 4. At this time, the moving wooden board body 7 can come into contact with the blade body 302 of the cloud core to realize the processing operation. Until the wooden board body 7 separates from the arc-shaped slide 5, the arc-shaped slide 5 can be reset again by the cooperation of the return spring 401, which improves the protection effect and safety of the blade body 302, while avoiding the elastic end plate 1401 from contacting the running blade body 302 and causing damage.

[0029] Specifically, a feed rack 6 is fixedly installed on the outside of the tool assembly 3. The feed rack 6 is used to discharge the wood chips generated during the processing of the wood board body 7.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the present invention should still fall within the scope of the present invention.
