Description

Technical Field

[0001] The utility model relates to the technical field of wooden gift box processing, in particular to a dust-proof wooden gift box grinding machine. Background Technique

[0002] A wooden gift box refers to a packaging box made of wood boards and wood materials, which can improve the grade of the commodity itself. Due to the selection of materials, workmanship and accessories, the price of the wooden box packaging is higher than other packaging forms. For wooden gift boxes, they need to be processed by cutting, grinding, riveting and other methods. During the grinding process, the falling of wood chips is likely to affect the production environment;

[0003] Publication No. CN210499648U discloses a wood grinding machine convenient for dust removal. The wood is first inserted through the feeding roller on one side, and then enters between the two grinding rollers to be ground. After the power is turned on, the suction fan works. The sawdust after grinding remains on the workbench. The suction fan causes the pressure in the box to decrease, so that the sawdust is sucked into the box through the dust suction holes and falls into the box and is filtered by the filter screen;

[0004] However, the following problems still exist in the above dust-proof mechanism for wood grinding during actual use: Although the suction fan is used to promote the sawdust to enter the box for collection, different specifications of wood cannot be limited during actual processing, and the overall grinding needs to be held manually, making the grinding operation prone to dislocation. At the same time, the overall dust-proof mechanism is in an open state for a long time, and it is easy to diverge outward due to the grinding operation, thus affecting the collection of sawdust.

[0005] Therefore, we propose a dust-proof wooden gift box grinding machine to solve the problems raised above. Content of the Utility Model

[0029] See also Figures 1-6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem that the existing grinding mechanism cannot effectively limit the position of the wooden gift box, this embodiment adopts the following technical scheme, wherein the rotation of the main bidirectional threaded rod 3 drives the locking frames 7 on the left and right sides to move, so as to adapt to the left and right lengths of wooden gift boxes of different specifications, and then the rotating transmission shaft 6 drives the secondary bidirectional threaded rod 8 inside the locking frame 7 to rotate, thereby driving the positioning brackets 12 threadedly connected on the front and rear sides to move, so that the positioning brackets 12 are limited to the corners of the wooden gift box to prevent it from being offset during the processing process;

[0031] A dustproof wooden gift box polishing machine comprises a positioning platform 1, and a positioning sliding groove 2 provided inside the positioning platform 1; main bidirectional threaded rods 3 are rotatably provided on both front and rear sides of the positioning sliding groove 2 inside the positioning platform 1 through bearings, and guide slide blocks 4 are slidably provided on the left and right outer walls of the main bidirectional threaded rods 3 on both front and rear sides; the left ends of the main bidirectional threaded rods 3 on both front and rear sides inside the positioning sliding groove 2 are connected to each other through a sprocket mechanism 20, and the right end of the front main bidirectional threaded rod 3 is fixedly connected to the output shaft end of a servo motor 11, and the middle parts of the main bidirectional threaded rods 3 on both front and rear sides are provided inside a dustproof platform 9 included in the dustproof mechanism;

[0032] A bearing plate 5 is fixedly arranged in the middle at the rear of the positioning platform 1, and a transmission rotating shaft 6 is rotatably arranged on the top surface of the bearing plate 5 through a bearing; wherein, locking mechanisms are arranged on both the left and right sides of the positioning sliding groove 2 inside the positioning platform 1, and each locking mechanism includes a locking frame 7 and a secondary bidirectional threaded rod 8; the locking frame 7 included in the locking mechanism is fixedly installed at the top of the front and rear guide sliders 4, and the secondary bidirectional threaded rod 8 included in the locking mechanism is rotatably arranged inside the left and right locking frames 7 through a bearing, and the front and rear outer walls of the left and right secondary bidirectional threaded rods 8 are threadedly connected to the outer ends of the positioning brackets 12;

[0033] The positioning brackets 12 included in the locking mechanism are all arranged in an "L" - shaped structure, and the bottom horizontal height of the symmetrically arranged positioning brackets 12 is higher than the top surface horizontal height of the positioning platform 1, and the symmetrically arranged positioning brackets 12 are installed in a way of two in a group and symmetrically distributed about the vertical central axis of the positioning platform 1, and the four corners of the gift box are locked and positioned through the symmetrically arranged positioning brackets 12; the right end of the transmission rotating shaft 6 is rotatably connected to the output shaft end of the driving motor 13 through a bearing, and the rear end of the transmission rotating shaft 6 and the secondary bidirectional threaded rod 8 included in the locking mechanism are meshed and connected through a bevel gear set 14, and the bevel gear sets 14 on the outer wall of the transmission rotating shaft 6 are connected in a slidable clamping manner, and the bevel gear sets 14 on the outer wall of the transmission rotating shaft 6 and the bevel gear sets 14 on the outer wall of the secondary bidirectional threaded rod 8 are connected through a locking buckle piece 15;

[0034] As Figure 2 , Figure 5 shown, first place the wooden gift box above the positioning platform 1, and then drive the servo - motor 11, so that it drives the main bidirectional threaded rod 3 on the front and rear sides inside the positioning sliding groove 2 to rotate through the sprocket mechanism 20. Then, the main bidirectional threaded rod 3 drives the guide sliders 4 threadedly connected to its left and right outer walls to move synchronously, so that the guide sliders 4 drive the locking frames 7 fixedly connected to their tops to be adapted to the left and right ends of the wooden gift box synchronously, so that the inner ends of the positioning brackets 12 in an "L" - shaped structure arranged on the top of the locking frame 7 first fit against the left and right sides of the wooden gift box;

[0035] Furthermore, during the movement of the locking frame 7, the bevel gear group 14 at the rear end of the internal secondary bidirectional threaded rod 8 is connected by a locking buckle 15, and the bevel gear group 14 on the outer wall of the transmission shaft 6 is connected in a sliding snap-fit manner, so that the locking buckle 15 can ensure that the bevel gear group 14 is in a state of mutual meshing to prevent mutual disengagement during the movement, and then the driving motor 13 works, which drives the transmission shaft 6 to rotate on the top of the supporting plate 5, and then the rotating transmission shaft 6 drives the bevel gear group 14 to rotate the meshing secondary bidirectional threaded rod 8, so that the secondary bidirectional threaded rod 8 drives the positioning bracket 12 threadedly connected to the front and rear outer walls to move synchronously toward the front and rear outer walls of the wooden gift box, so that the wooden gift box can be locked and positioned by the "L"-shaped positioning bracket 12.

[0036] Embodiment 2: In order to solve the problem that the dustproof component of the existing grinding mechanism cannot prevent the wood chips from leaking outward, this embodiment adopts the following technical scheme, through the grinding mechanism descending, the wooden gift box after positioning is polished, the grinding mechanism presses the resisting spring piece 19 on the outer wall of the guide slide bar 17 to descend, so that the traction steel cable 16 at its inner end does not pull the dust cover plate 10 in a relaxed state, and the dust cover plate 10 slides outward on the top surface of the dustproof platform 9 under the action of the elastic connection, and then the wood chips from grinding are collected through the opened dustproof platform 9;

[0037] Among them, a dustproof mechanism is fixedly arranged at the center position of the positioning sliding groove 2 inside the positioning platform 1, and the dustproof mechanism includes a dustproof platform 9 and a dustproof cover plate 10; the dustproof platform 9 included in the dustproof mechanism is arranged at the center position of the positioning sliding groove 2 inside the positioning platform 1, and the dustproof cover plate 10 included in the dustproof mechanism elastically slides on the front and rear sides of the top surface of the dustproof platform 9, and the top surfaces of the front and rear dustproof cover plates 10 are fixedly connected to the inner end of the traction cable 16;

[0038] The top surface of the dustproof platform 9 is fixedly provided with guide slide bars 17 on both the front and rear sides, and the upper outer walls of the guide slide bars 17 on both the front and rear sides are slidably provided with resisting springs 19 through return springs 18, and the resisting springs 19 on both the front and rear sides are fixedly connected to the outer ends of the traction cables 16 on the upper sides of the dustproof cover plates 10 on both the front and rear sides, and the resisting springs 19 slide as the grinder descends;

[0039] like Figures 2-4As shown, when the grinding mechanism grinds the wooden gift box, the grinding mechanism descends towards the positioning platform 1. When it descends to the top of the guiding slide rod 17, the grinding mechanism compresses the contact elastic sheet 19 on the outer wall of the guiding slide rod 17 to descend synchronously, and compresses the return spring 18. Then, the descending contact elastic sheet 19 relaxes the traction cable 16 fixedly connected to its inner end. Without traction, the traction cable 16 relaxes the dust-proof cover plate 10 fixedly connected to its inner end, causing the dust-proof cover plate 10 elastically connected to the top surface of the dust-proof platform 9 to slide outward synchronously without external traction. Then, the opened dust-proof platform 9 collects the sawdust generated during grinding;

[0040] Furthermore, after the grinding work is completed, the grinding mechanism slides upward. After the compressed contact elastic sheet 19 is no longer under pressure, it is driven by the return spring 18 to rise and reset, thereby tightening the traction cable 16 fixedly connected to its inner end. During the tightening process, the traction cable 16 drives the dust-proof cover plate 10 on the top surface of the dust-proof platform 9 to slide inward, thereby closing the dust-proof platform 9 to prevent the sawdust collected inside from leaking out and affecting the processing environment, etc.

[0041] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
