DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a core-inserting device for producing wood-plastic environmental protection pencils includes a fixed platform 1 fixedly connected with fixed feet 3 at the bottom. A placement box 7 is horizontally slidably installed on the top of the fixed platform 1. A lead core groove 2 is opened at the top of the fixed platform 1. The cross-section of the lead core groove 2 is in a "U" shape, and the top of the lead core groove 2 is an open structure. The distance between the lowest point and the highest point of the lead core groove 2 is equal to the diameter of the lead core. A shaking mechanism is installed at the back end of the placement box 7, and a pushing mechanism is installed at the back end of the fixed platform 1. The shaking mechanism is used to drive the placement box 7 to shake left and right at a constant speed, and the pushing mechanism is used to push the lead core located in the inner cavity of the lead core groove 2 into the wood-plastic board.
[0019] In this embodiment: First, the lead core is placed into the interior of the placement box 7 along the length direction of the lead core groove 2. Then, the shaking mechanism is started. The shaking mechanism drives the placement box 7 to shake back and forth. During the process of the placement box 7 shaking back and forth, the lead core in the placement box 7 shakes accordingly. During the shaking of the lead core, the lowermost lead core enters the lead core groove 2 during the shaking process, and the subsequent lead cores cannot enter the lead core groove 2. When the wood-plastic board with a lead groove moves to the front end of the fixed platform 1 by the conveying device, at this time, the pushing mechanism is started to push the lead core located in the lead core groove 2 into the lead groove of the wood-plastic board, completing the core-inserting operation.
[0020] Please refer specifically to Figure 2 , the shaking mechanism includes a vertical rail 8 fixedly connected to the back end of the placement box 7. Brackets are installed on both sides of the back end of the fixed platform 1. A rotary motor 9 is installed on the brackets. The output end of the rotary motor 9 is connected with a cam 10. One end of the cam 10 is installed with a rotating wheel 19 through a rotating shaft, and the rotating wheel 19 is movably connected to the inner wall of the vertical rail 8.
[0021] In this embodiment: By starting the rotary motor 9, the rotary motor 9 drives the cam 10 at its output end to rotate. Since the rotating shaft is installed at an eccentric position of the cam 10, there are the leftmost point and the rightmost point during the rotation of the rotating shaft along with the cam 10. Therefore, during the rotation of the rotating wheel 19, the vertical rail 8 drives the placement box 7 to slide left and right reciprocally. At the same time, during the left and right movement of the rotating wheel 19 along the vertical rail 8, the rotating wheel 19 slides up and down along the inner wall of the vertical rail 8.
[0022] Please refer specifically to Figure 2 AndFigure 3 The pushing mechanism includes two limiting shafts 11 symmetrically and fixedly connected to the back end of the fixed platform 1. The outer wall of the limiting shaft 11 is axially slidably connected with a cross plate 13. One end of the cross plate 13 located between the two limiting shafts 11 is fixedly connected with a plurality of push rods 15. The plurality of push rods 15 are aligned with the plurality of lead core grooves 2 one by one. An electric push cylinder 18 is installed at the bottom end of the fixed platform 1. The output end of the electric push cylinder 18 is fixedly connected with a fixed ear 17. The top end of the fixed ear 17 is fixedly connected with the bottom end of the cross plate 13.
[0023] In this embodiment: When pushing the lead core into the lead groove of the wood-plastic board, start the electric push cylinder 18. The electric push cylinder 18 drives the cross plate 13 to move through the fixed ear 17. The cross plate 13 drives the plurality of push rods 15 to move synchronously. During the movement, the push rods 15 are inserted into the lead core grooves 2, so as to push out the lead core on the inner wall of the lead core grooves 2. During this process, the cross plate 13 slides along the outer walls of the two limiting shafts 11. The limiting shafts 11 limit the moving direction of the cross plate 13, avoiding the situation that the cross plate 13 moves offset when the connection between the fixed ear 17 and the electric push cylinder 18 becomes loose.
[0024] Please refer specifically to Figure 1 and Figure 2 , both sides of the top end of the fixed platform 1 are fixedly connected with connecting plates 4. Both sides of the placement box 7 are integrally formed with sliding shafts 5 that are slidably connected to the connecting plates 4. A return spring 6 is fixedly connected between the connecting plates 4 and the placement box 7. The return spring 6 is sleeved on the sliding shaft 5.
[0025] In this embodiment: During the process of the placement box 7 shaking left and right, the placement box 7 drives the two sliding shafts 5 to act synchronously. The two sliding shafts 5 slide with the connecting plates 4 respectively. During this process, one return spring 6 is compressed and the other return spring 6 is stretched. The setting of the two return springs 6 can assist the reset of the placement box 7.
[0026] Please refer specifically to Figure 2 and Figure 3 , a connecting spring 12 is fixedly connected between the back end of the fixed platform 1 and the cross plate 13. The connecting spring 12 is sleeved on the limiting shaft 11.
[0027] In this embodiment: When the cross plate 13 performs a pushing action, the connecting spring 12 is compressed. After the pushing is completed, the connecting spring 12 can assist the cross plate 13 to reset.
[0028] Please refer specifically to Figure 2 and Figure 3 , a bracket 16 for supporting the push rod 15 is fixedly connected between the back ends of the fixed platform 1 and located between the two limiting shafts 11. A receiving groove 14 that matches the outer wall of the bracket 16 is opened inside the limiting shaft 11.
[0029] In this embodiment: The fully reset push rod 15 has its end resting in the groove of the bracket 16, which can ensure that the push rod 15 is always aligned with the lead core groove 2.
[0030] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
