Description

Technical Field

[0001] The present invention belongs to the technical field of log processing, and specifically relates to a device for processing, trimming and polishing log round timbers. Background Art

[0002] During the process of cutting wood, there are generally still a lot of burrs remaining around the wooden round blocks just after cutting. In order to facilitate the next-step processing, it is necessary to remove the burrs remaining around the wooden round blocks. Currently, generally, the burrs are removed by polishing and grinding the periphery of the wooden round blocks.

[0003] Most of the existing polishing devices use abrasive belts to polish the circumferences of wooden round blocks. For example, a grinding device for polishing wooden round blocks with the publication number of CN112223042A mainly polishes the periphery of wooden round blocks through the grinding of the abrasive belt. Through the cooperation of the linkage mechanism and the rotating mechanism, the wooden round block can be rotated, so that the periphery of the wooden round block can be polished all-round.

[0004] When the existing grinding device is in use, since the rotating mechanism is fixedly lifted and lowered, it is not easy for the rotating mechanism to locate the center of the wooden round block, which causes the rotating mechanism to drive the wooden round block to rotate at a non-center position, resulting in the wooden round block rotating irregularly along a non-center. When the abrasive belt polishes the wooden round block, there is an easy phenomenon that some local positions of the wooden round block cannot be polished. Summary of the Invention

[0013] Beneficial effects of the present invention:

[0014] (1) The present invention places a strong magnet on the top of the wooden block.

[0034] Specifically, the feeding component 5 includes a blanking bucket 501 and a fixing ring 502, the base 1 is fixedly connected to the blanking bucket 501 through the fixing ring 502, wooden round blocks to be polished are placed in the blanking bucket 501, and as the turntable 701 rotates, the wooden round blocks inside the blanking bucket 501 automatically fall into the feeding groove 703 on the turntable 701.

[0035] Specifically, the feeding assembly 7 includes a turntable 701 and a cam 702, the turntable 701 is coaxially connected with the cam 702 and driven by a power assembly, a feed trough 703 is provided on the turntable 701, and the pushing assembly 9 includes a push platform 901, an inclined push rod 902 is obliquely slidably installed in the push platform 901, and the inclined push rod 902 is connected to the inner wall of the push platform 901 through an inclined spring 903; the feeding assembly 5 feeds the wooden round block into the feed trough 703, the power assembly drives the turntable 701 and the cam 702 to rotate synchronously, the turntable 701 transports the wooden round block to the centering assembly 8, and the cam 702 lifts the inclined push rod 902, so that the inclined push rod 902 pushes the wooden round block toward the grinding assembly 2.

[0036] It should be noted that see Figure 5 The installation position of the isolation sleeve 609 is shown in the figure. The installation position of the isolation sleeve 609 does not interfere with the movement of the universal joint 606. The purpose of the screw lift 611 is to drive the lifting rod 610 to move up and down. The screw lift 611 is a prior art, and the working principle of the screw lift 611 is not described in detail in this application. The special-shaped magnets 810 are arranged in several groups. The reliability of centering can be improved by using multiple groups of special-shaped magnets 810. The power component drives the feeding component 7 to run intermittently.

[0037] It should be noted that when in use, the wooden round blocks to be polished are placed in the drop barrel 501, and the turntable 701 and the cam 702 are driven to rotate synchronously by the power assembly. As the turntable 701 rotates, the wooden round blocks inside the drop barrel 501 fall into the feed slot 703 on the turntable 701, and the wooden round blocks are transported to the top of the rotating disk 802 through the turntable 701; as the cam 702 rotates, the cam 702 pushes the inclined push rod 902 to move, so that the inclined push rod 902 pushes the wooden round blocks on the rotating disk 802 to abut against the polishing belt 202.

[0038] The vacuum suction cup 803 is started to absorb the wooden ball and fix the wooden ball on the rotating disk 802. Then the screw lifting platform 611 is started. The screw lifting platform 611 drives the lifting rod 610 to move down along the isolation sleeve 609 and stops when the strong magnet 612 on the lifting rod 610 is placed on the top of the wooden ball.

[0039] Start the motor 201, the motor 201 drives the grinding belt 202 to run through the transmission roller 203, see Figure 13 As the wooden block contacts the grinding belt 202, the grinding belt 202 drives the wooden block to rotate. Under the fixation of the vacuum suction cup 803, the wooden block and the rotating disk 802 rotate synchronously. As the strong magnet 612 is placed on the top of the wooden block, the strong magnet 612 will absorb the special-shaped magnet 810 in the rotating disk 802 through the wooden block. As the rotating disk 802 rotates, the wooden block rotates along the rotating disk 802. Figure 13The special-shaped magnet 810 of the dotted line track is attracted by the strong magnet 612, see Figure 12 , so that the special-shaped magnet 810 moves up along the slide groove 811, see Figure 11 As the shaped magnet 810 moves upward, the spring 1 809 is compressed, and the shaped magnet 810 pops out of the rotating disk 802. When the shaped magnet 810 moves upward, the slide bar 816 moves along the side wall of the shaped magnet 810. When the shaped magnet 810 pops out of the rotating disk 802, the slide bar 816 abuts against the connecting rod 807 at the bottom of the shaped magnet 810. Figure 13 The irregular magnet 810 emerges from the circular dotted line track; when the rotating disk 802 rotates, see Figure 9 Under the action of the bidirectional lead screw 804 and the transmission sleeve 806, the rotating disk 802 drives the lifting disk 805 to move downward, so that the lifting disk 805 drives other unemerged special-shaped magnets 810 to slide toward the bottom of the slide groove 811 through the connecting rod 807, so that the special-shaped magnet 810 extends into the slide groove 811. When the special-shaped magnet 810 moves to a fixed position, the sliding rod 816 blocks the top of the special-shaped magnet 810, and then the lifting rod 610 is collected into the isolation sleeve 609 through the lead screw lifting platform 611.

[0040] Start the cylinder 601, and drive the lifting plate 602 downward through the cylinder 601, and start the annular electromagnetic disk 607 at the same time, so that the annular electromagnetic disk 607 absorbs the special-shaped magnet 810 emerging from the slide groove 811, and the wooden block is clamped between the annular electromagnetic disk 607 and the special-shaped magnet 810. Then, the universal joint 606 is driven to rotate by the motor 2 603, so that the universal joint 606 drives the wooden block to rotate in the opposite direction, so that the grinding belt 202 grinds the side of the wooden block.

[0041] The present invention places a strong magnet 612 on the top of the wooden block. As the wooden block rotates synchronously with the rotating disk 802, the strong magnet 612 absorbs the special-shaped magnet 810 in the rotating disk 802 through the wooden block, so that the special-shaped magnet 810 emerges along the rotation center of the wooden block. Then, the center position of the wooden block is fixed by the annular electromagnetic disk 607 to absorb the special-shaped magnet 810, so that the grinding component 2 grinds the wooden block evenly, avoiding the phenomenon that a local position of the wooden block cannot be polished.

[0042] It should be noted that the electromagnetic suction cup 815 adsorbs the metal disk 817 so that the metal disk 817 releases the position restriction on the special-shaped magnet 810 and the special-shaped magnet 810 is reset.

[0043] It should be noted that if the polishing belt 202 polishes the side of the wooden round block while maintaining the same horizontal position, streaks will appear on the wooden round block, affecting the quality of the wooden round block. When the polishing belt 202 polishes the side of the wooden round block, only the part of the polishing belt 202 that contacts the side of the wooden round block can be utilized, and the part of the polishing belt 202 that does not contact the side of the wooden round block cannot be utilized, resulting in poor utilization rate of the polishing belt 202 and reduced service life.

[0044] Based on this, when the second motor 603 drives the wooden round block and the rotating disk 802 to reverse, under the transmission cooperation of the bidirectional lead screw 804 and the transmission sleeve 806, the bidirectional lead screw 804 drives the lifting disk 805 to move upward, closing the vacuum suction cup 803. When the lifting disk 805 moves upward, the lifting disk 805 drives the special-shaped magnet 810 to lift the wooden round block through the connecting rod 807. As the rotating disk 802 continues to rotate, the lifting disk 805 drives the special-shaped magnet 810 to reciprocate up and down through the connecting rod 807, so that the special-shaped magnet 810 drives the wooden round block to move synchronously, improving the utilization rate of the polishing belt 202 and avoiding streaks on the side of the wooden round block.

[0045] It should be noted that a fan can be installed on the baffle 3 to blow away the powder on the vacuum suction cup 803 to ensure the use efficiency of the vacuum suction cup 803.

[0046] See Figure 4 , the rotating assembly 6 further includes a cylinder 601. The cylinder 601 is installed on the baffle 3, and the output end of the cylinder 601 is connected to the lifting plate 602. An insulating sleeve 609 is installed on the connecting platform 608, and the lifting rod 610 moves up and down within the insulating sleeve 609.

[0047] Specifically, a connecting plate 808 is installed on the connecting rod 807. The connecting plate 808 slides within the lifting disk 805, and the connecting plate 808 is connected to the lifting disk 805 through a first spring 809. The moving frame 814 is connected to the inner wall of the second chute 812 through a third spring 819. An electromagnetic chuck 815 is installed within the moving frame 814. A metal disk 817 is installed on the sliding rod 816. The electromagnetic chuck 815 adsorbs the metal disk 817, and the metal disk 817 is connected to the moving frame 814 through a second spring 818.

[0048] It should be noted that when the special-shaped magnet 810 is blocked inside the first chute 811 by the sliding rod 816, when the lifting disk 805 moves upward through the connecting rod 807, the special-shaped magnet 810 can push the moving frame 814 to move along the second chute 812.

[0049] See Figures 1 - 3 , the polishing assembly 2 includes a first motor 201. The first motor 201 is installed on the base 1, and the first motor 201 drives the polishing belt 202 to run through a transmission roller 203.

[0050] It should be noted that the grinding belt 202 of the present invention is arranged horizontally, and the rotating component 6 drives the wooden round block to grind in a reverse manner along the tangent direction of the grinding belt 202. During this process, the side grinding of the wooden round block can be accelerated to improve the grinding efficiency.

[0051] See also Figures 1 - 2 A material box 4 is installed on the base 1, and a feeding assembly 7 transports the polished wooden round blocks to the material box 4.

[0052] It should be noted that the polished wooden round blocks are transported to the blanking box 4 by the feeding assembly 7, so that the entire polishing process can be carried out in an orderly manner.

[0053] Working principle of the present invention: When the present invention is in use, the wooden round block to be polished is placed in the drop barrel 501, and the turntable 701 and the cam 702 are driven to rotate synchronously by the power component. As the turntable 701 rotates, the wooden round block inside the drop barrel 501 falls into the feed slot 703 on the turntable 701, and the wooden round block is transported to the top of the rotating disk 802 through the turntable 701; as the cam 702 rotates, the cam 702 pushes the inclined push rod 902 to move, so that the inclined push rod 902 pushes the wooden round block on the rotating disk 802 to abut against the polishing belt 202.

[0054] The vacuum suction cup 803 is started to absorb the wooden ball and fix the wooden ball on the rotating disk 802. Then the screw lifting platform 611 is started. The screw lifting platform 611 drives the lifting rod 610 to move down along the isolation sleeve 609 and stops when the strong magnet 612 on the lifting rod 610 is placed on the top of the wooden ball.

[0055] Start the motor 201, the motor 201 drives the grinding belt 202 to run through the transmission roller 203, see Figure 13 As the wooden block contacts the grinding belt 202, the grinding belt 202 drives the wooden block to rotate. Under the fixation of the vacuum suction cup 803, the wooden block and the rotating disk 802 rotate synchronously. As the strong magnet 612 is placed on the top of the wooden block, the strong magnet 612 will absorb the special-shaped magnet 810 in the rotating disk 802 through the wooden block. As the rotating disk 802 rotates, the wooden block rotates along the rotating disk 802. Figure 13 The special-shaped magnet 810 of the circular dotted line track is attracted by the strong magnet 612, see Figure 12 , so that the special-shaped magnet 810 moves up along the slide groove 811, see Figure 11 As the shaped magnet 810 moves upward, the spring 1 809 is compressed, and the shaped magnet 810 emerges from the rotating disk 802. When the shaped magnet 810 moves upward, the slide bar 816 moves along the side wall of the shaped magnet 810. When the shaped magnet 810 emerges from the rotating disk 802, the slide bar 816 abuts against the connecting rod 807 at the bottom of the shaped magnet 810. Figure 13A circular dotted line trajectory emerges; when the rotating disk 802 rotates, refer to Figure 9 , under the action of the bidirectional lead screw 804 and the transmission sleeve 806, the rotating disk 802 drives the lifting disk 805 to move downward, so that the lifting disk 805 drives other non-emerged special-shaped magnets 810 to slide towards the bottom of the first chute 811 through the connecting rod 807, causing the special-shaped magnets 810 to extend into the first chute 811. When the special-shaped magnets 810 move to the fixed position, the slide rod 816 rebounds to block the special-shaped magnets 810 in the first chute 811, and then the lifting rod 610 is retracted into the isolation sleeve 609 through the screw jack 611.

[0056] Start the cylinder 601, drive the lifting plate 602 to move downward through the cylinder 601, and at the same time start the annular electromagnetic disk 607. The annular electromagnetic disk 607 adsorbs the special-shaped magnets 810 emerging from the first chute 811. At this time, the wooden round block is clamped between the annular electromagnetic disk 607 and the special-shaped magnets 810. Then drive the universal joint 606 to rotate through the second motor 603, so that the universal joint 606 drives the wooden round block to rotate in the reverse direction. At this time, the grinding belt 202 grinds the side of the wooden round block.

[0057] Specifically, when the second motor 603 drives the wooden round block and the rotating disk 802 to rotate in reverse, under the transmission cooperation of the bidirectional lead screw 804 and the transmission sleeve 806, the bidirectional lead screw 804 drives the lifting disk 805 to move upward, and the vacuum chuck 803 is closed. When the lifting disk 805 moves upward, the lifting disk 805 drives the special-shaped magnets 810 to lift the wooden round block through the connecting rod 807; as the rotating disk 802 continues to rotate, the lifting disk 805 drives the special-shaped magnets 810 to reciprocate up and down through the connecting rod 807, so that the special-shaped magnets 810 drive the wooden round block to move synchronously, improving the utilization rate of the grinding belt 202 and avoiding the grinding belt 202 grinding the wooden round block at the same position, resulting in streaks on the side of the wooden round block.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
