A CNC machine tool for automatically feeding wood in wood processing

Abstract

This utility model relates to the field of wood processing technology, specifically to an automatic wood-pushing CNC machine tool for wood processing. It includes a pushing mechanism comprising a bed frame with an inner groove on its inner wall. An inner plate is provided on the inner surface of the inner groove, and the inner surface of the inner groove is slidably connected to the outer side of one end of the inner plate. A connecting rod is provided at the other end of the inner plate. In this automatic wood-pushing CNC machine tool, when the drive rod moves, the limiting rod no longer obstructs the bottom of the movable arm. Thus, when the movable arm is unobstructed, the spring sheet uses its own retraction ability to move the pressure plate downwards. At this time, the pressure plate restricts the board material. Simultaneously, during the downward movement of the pressure plate, an insert rod is designed on the bottom side of the pressure plate, which enters the drive rod, thereby enabling the board material to be moved and fixed simultaneously. This structural design allows the board material to move according to a predetermined path and speed during processing.

Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to a CNC machine tool for automatically pushing wood. Background Technology

[0002] Timber processing refers to the process of using timber as raw material and employing various mechanical, chemical, or biological methods to cut, dry, glue, and surface-decorate timber into products with specific shapes, properties, and uses. It encompasses a wide range of fields, from initial processing of logs after logging to the final production of various finished products such as furniture, building materials, pulp, and handicrafts.

[0003] In existing technologies, when wood is shaped into special shapes, CNC machine tools can accurately transform the designer's highly creative and complex designs into physical objects. Whether it is exquisite carvings, smooth curves, or unique irregular shapes, CNC machine tools can accurately process them according to preset programs, making special-shaped wood products more artistic and unique.

[0004] However, in the process of wood processing, manual external force is required to push the wood onto the machine tool. If the center of gravity is unstable during the pushing process, it will cause deviation. Since the position of the wood needs to be constantly adjusted by the human to correct the deviation, the wood is subjected to uneven external force during the correction, which will generate internal processing stress. This stress may cause problems such as deformation and cracking of the wood after processing. To address this, we propose a CNC machine tool for automatically pushing wood for wood processing. Utility Model Content

[0005] One of the technical problems this application aims to solve is: to avoid deviation in the movement path by automatically pushing and processing timber.

[0007] In some embodiments, the fixing mechanism includes a fixing arm, a locking block is provided on the inner wall of one end of the fixing arm, the inner wall of one end of the fixing arm is engaged with the outer side of the locking block, and the outer side of the locking block is engaged with the inner wall of the pressure plate.

[0008] In some embodiments, a side plate is provided on the top side of the pressure plate, the top side of the pressure plate is fixedly connected to the bottom end of the side plate, the inner wall of one end of the side plate is slidably connected through the outer side of the locking block, and one end of the fixing arm is rotatably connected to the inner wall of the pressure plate.

[0009] In some embodiments, the bottom end of the connecting rod is provided with a movable arm, the bottom end of the connecting rod is rotatably connected to the top end of the movable arm, the bottom end of the movable arm is slidably connected to the inner top surface of the bed frame, and the inner side of the bed frame is slidably connected to one side of the drive rod.

[0010] In some embodiments, a limiting rod is provided on the top side of the drive rod, and one end of the limiting rod is fixedly connected to the top side of the drive rod, while the other end of the limiting rod is slidably in contact with the bottom end of the movable arm.

[0011] In some embodiments, a motor is provided on the inner wall of the bed frame, and the inner wall of the bed frame is fixedly connected to the outer side of the motor. A fixed plate is provided at the output end of the motor, and the output end of the motor is fixedly connected to the center of the fixed plate. A lever is provided on one side of the fixed plate, and one side of the fixed plate is fixedly connected to one end of the lever. One end of the lever is rotatably engaged with a protrusion on one side of the drive rod.

[0012] In some embodiments, a spring is provided on the bottom side of the inner plate, the bottom side of the inner plate is fixedly connected to the top of the spring, and the bottom end of the spring is fixedly connected to the inner top surface of the bed frame.

[0013] In some embodiments, a baffle is provided on the inner side of the bed frame, and one end of the baffle is fixedly connected to the inner side of the bed frame. A processing device is provided on the top side of the baffle, and the top side of the baffle is fixedly connected to the bottom end of the processing device.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. Because the fixed plate rotates in stages, the lever contacts the protrusion on the side of the drive rod once for each rotation. This causes the drive rod to move short distances in stages within the bed frame. When the drive rod moves, the limit rod no longer blocks the bottom of the movable arm. Since there are spring pieces at both ends of the inner plate, when the movable arm is unobstructed, the spring pieces use their own retraction ability to move the pressure plate down. At this time, the pressure plate will restrict the plate. At the same time, during the downward movement of the pressure plate, since there is an insertion rod designed on the bottom side of the pressure plate, the insertion rod will enter the drive rod. This creates a structural connection between the drive rod and the pressure plate, which allows the plate to be moved and fixed at the same time. Through automated pushing and fixing, this structural design allows the plate to move according to a predetermined path and speed during processing.

[0016] 2. Extend the fixed arm from the pressure plate to change the overall shape from I to U. This increases the contact area with the board during the pressing process, enhances the fixing effect on the board, and prevents the board from shifting or shaking during processing. At the same time, the U-shaped structure can better adapt to boards of different sizes and shapes, improving the versatility of the equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 5 This utility model provides a technical solution: an automatic wood processing CNC machine tool for pushing wood, including a pushing mechanism 1, a fixing mechanism 2 provided on the inner wall of the pushing mechanism 1, the pushing mechanism 1 including a bed frame 11, an inner groove 112 formed on the inner wall of the bed frame 11, an inner plate 12 provided on the inner surface of the inner groove 112, the inner surface of the inner groove 112 being slidably connected to the outer side of one end of the inner plate 12, a connecting rod 14 provided on the other end of the inner plate 12, the other end of the inner plate 12 being slidably connected to a recessed part on one side of the connecting rod 14, and the top end of the connecting rod 14 being... A pressure plate 13 is provided, and the top end of the connecting rod 14 is fixedly connected to the bottom side of the pressure plate 13. An insertion rod 18 is provided on the bottom side of the pressure plate 13, and the bottom side of the pressure plate 13 is fixedly connected to the top end of the insertion rod 18. A drive rod 16 is provided on the outer side of the insertion rod 18, and the outer side of the insertion rod 18 is engaged with the inner side of one end of the drive rod 16. A movable arm 15 is provided at the bottom end of the connecting rod 14, and the bottom end of the connecting rod 14 is rotatably connected to the top end of the movable arm 15. The bottom end of the movable arm 15 is slidably connected to the inner top surface of the bed frame 11. The inner side of the bed frame 11 is connected to the drive rod 16. A sliding connection is provided on one side. A limit rod 17 is provided on the top side of the drive rod 16. The top side of the drive rod 16 is fixedly connected to one end of the limit rod 17. The other end of the limit rod 17 is slidably contacted with the bottom end of the movable arm 15. A motor 113 is provided on the inner wall of the bed frame 11. The inner wall of the bed frame 11 is fixedly connected to the outer side of the motor 113. A fixed plate 19 is provided at the output end of the motor 113. The output end of the motor 113 is fixedly connected to the center of the fixed plate 19. A lever 110 is provided on one side of the fixed plate 19. A lever 110 is provided on one side of the fixed plate 19. One end of block 110 is fixedly connected, and one end of push block 110 is rotatably engaged with a protrusion on one side of drive rod 16. A spring piece 115 is provided on the bottom side of inner plate 12, and the bottom side of inner plate 12 is fixedly connected to the top of spring piece 115. The bottom end of spring piece 115 is fixedly connected to the inner top surface of bed frame 11. A baffle 111 is provided on the inner side of bed frame 11, and one end of baffle 111 is fixedly connected to the inner side of bed frame 11. A processing device 114 is provided on the top side of baffle 111, and the top side of baffle 111 is fixedly connected to the bottom end of processing device 114.

[0026] When this type of automatic wood-pushing CNC wood processing machine tool is in use, a processing device 114 is installed at one end of the bed frame 11. The board is put into the processing device 114 from one end and pushed along the top side of the bed frame 11 until it is pushed to the side of the connecting rod 14. In order to push the board in an automated manner during the processing, when the board is close to the connecting rod 14, the motor 113 is started to make the fixed plate 19 rotate. The rotation is a staged rotation. Since a lever 110 is designed on one side of the fixed plate 19, the lever 110 will contact the protrusion on the side of the drive rod 16 once every time the fixed plate 19 rotates. When contacting, the lever 110 uses the external force of rotation to move the drive rod 16, thereby causing the drive rod 16 to move a short distance in stages within the bed frame 11.

[0027] Because a limit rod 17 is designed on the drive rod 16, the limit rod 17 no longer obstructs the bottom end of the movable arm 15 when the drive rod 16 moves. The top end of the movable arm 15 is rotatably connected to a connecting rod 14, and the top end of the connecting rod 14 is fixed to the pressure plate 13. In order for the pressure plate 13 to automatically move down and be positioned on the plate after the resistance disappears, an inner plate 12 is connected to the recessed part on the side of the connecting rod 14. Both ends of the inner plate 12 are provided with spring pieces 115. In this way, when the movable arm 15 is not obstructed, the spring pieces 115 use their own retraction ability to keep the connecting rod 14, the pressure plate 13 and the inner plate 12 together. As the plate moves downward, the pressure plate 13 restricts the plate material. During this downward movement, the pressure plate 13 has a rod 18 on its bottom side that enters the drive rod 16, creating a structural connection between the drive rod 16 and the pressure plate 13. This allows the plate material to be moved and fixed simultaneously, achieving precise positioning and stable pushing. The automated pushing and fixing method reduces manual intervention. This structural design enables the plate material to move along a predetermined path and speed during processing, ensuring the continuity and stability of the processing.

[0028] When resetting each component, simply ensure that the toggle block 110 is no longer in contact with the drive rod 16. Then, by using a rod-like object to push one end of the drive rod 16 back to its original position, the limit rod 17 will re-engage with the movable arm 15 and create resistance, thereby restoring each component to its original state. Finally, a baffle 111 is installed on the inner side of the bed frame 11. The baffle 111 effectively prevents the movable arm 15 from accidentally entering the fixed plate 19 area during movement.

[0029] Example 2: Please refer to Figure 1 - Figure 5The fixing mechanism 2 includes a fixing arm 21. A locking block 22 is provided on the inner wall of one end of the fixing arm 21. The inner wall of one end of the fixing arm 21 is engaged with the outer side of the locking block 22. The outer side of the locking block 22 is engaged with the inner wall of the pressure plate 13. A side plate 23 is provided on the top side of the pressure plate 13. The top side of the pressure plate 13 is fixedly connected to the bottom end of the side plate 23. The inner wall of one end of the side plate 23 is slidably connected with the outer side of the locking block 22. One end of the fixing arm 21 is rotatably connected to the inner wall of the pressure plate 13.

[0030] A fixing arm 21 is provided on the inner side of the pressure plate 13. By unfolding the fixing arm 21 from the pressure plate 13, the overall shape changes from I to U. This increases the contact area with the board during the pressing process, enhances the fixing effect on the board, and prevents the board from shifting or shaking during processing. At the same time, the U-shaped structure can better adapt to boards of different sizes and shapes, improving the versatility of the equipment. After the unfolding is completed, a side plate 23 is designed on the top side of the pressure plate 13, and a cross locking block 22 runs through the side plate 23. The locking block 22 is engaged between the fixing arm 21 and the pressure plate 13, so that the fixing arm 21 remains stationary in the unfolded position, thereby increasing the pressing effect on the board.

[0031] Please see Figure 1 - Figure 5 The fixed disk 19 is powered to rotate by starting the motor 113. The rotation is phased. A lever 110 is designed on one side of the fixed disk 19. During the rotation of the fixed disk 19, the lever 110 contacts the protrusion on the side of the drive rod 16 once per revolution. Upon contact, the lever 110 uses the external force of rotation to actuate the drive rod 16. A limit rod 17 is designed on the drive rod 16. When the drive rod 16 moves, the limit rod 17 no longer obstructs the bottom of the movable arm 15. A connecting rod 14 is rotatably connected to the top of the movable arm 15, and the top of the connecting rod 14 is fixed to the pressure plate 13. This is to ensure that the pressure plate 13 can... The connecting rod 14 is automatically lowered and positioned on the plate. Therefore, an inner plate 12 is connected to the recessed part on the side of the connecting rod 14. Both ends of the inner plate 12 are provided with spring pieces 115. When the movable arm 15 is not obstructed, the spring pieces 115 use their own retraction ability to move the connecting rod 14, the pressure plate 13 and the inner plate 12 down in sync. At this time, the pressure plate 13 will restrict the plate. At the same time, during the downward movement of the pressure plate 13, since there is an insertion rod 18 designed on the bottom side of the pressure plate 13, the insertion rod 18 will enter the drive rod 16. In this way, a structural connection will be formed between the drive rod 16 and the pressure plate 13, so that the plate can be moved and fixed at the same time, achieving the purpose of precise positioning and stable pushing of the plate.

[0032] By unfolding the fixed arm 21 from the pressure plate 13, the overall shape changes from I to U. This increases the contact area with the board during the pressing process, enhances the fixing effect on the board, and prevents the board from shifting or shaking during processing. After unfolding, a side plate 23 is designed on the top side of the pressure plate 13, and a cross locking block 22 runs through the side plate 23. The locking block 22 is engaged between the fixed arm 21 and the pressure plate 13, so that the fixed arm 21 remains stationary in the unfolded position.
