[0002] Milling processing on a milling machine will generate a large amount of waste chips. Recycling and smelting these waste chips is not only economical, but also can prevent the accumulation of waste chips from affecting the milling efficiency. Since the sizes of the waste chips are not the same and they are entangled and piled up, the size of the waste chip pile is much larger than the mass density ratio of the raw materials. Traditional collection devices need to prepare excess space for recycling, which is not only time-consuming and labor-intensive but also leads to low efficiency of re-smelting. Therefore, a screening mechanism is needed to classify and recycle the waste chips.

This solution collects the chips and large pieces of scraps in the chip waste while collecting the chip waste, eliminating the trouble of subsequent classification and improving the overall collection efficiency of the waste.

[0004] There are still several points for improvement in the above scheme: only a single screening can be performed, and the fine division of the scraps cannot be performed; the screening speed is slow, which is not conducive to improving work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 to Figure 6 As shown, a multi-volume chip screening mechanism includes a frame 1 and a screen 7 for filtering and classifying chips, a frame 2 for adjusting the inclination angle of the screen 7 and a vibrator 8 for vibrating the screen 7 to drop materials, the frame 2 includes a mosaic frame 3 for fixing the screen 7, a load-bearing plate 4 for supporting the screen 7, a rotating shaft 5 as the rotation center of the frame 2 and a knob 6 for adjusting the inclination angle of the frame 2, the number of frames 2 is at least two and one side of each frame 2 is connected to the frame 1 in sequence, the mosaic frame 3 is slidably connected to the other side of the frame 2, the screen 7 is arranged in the frame 2 and connected to one side of the mosaic frame 3, the vibrator 8 is connected to the other side of the mosaic frame 3, the load-bearing plate 4 is installed on the side of the frame 2 and is slidably connected to the screen 7, the rotating shaft 5 is arranged at the center of the side of the frame 2 and passes through the frame 1, and the knob 6 is installed on the shaft end of the rotating shaft 5.

[0026] The frame 2 and the interlocking frame 3 are used to limit the moving range of the screen 7, and the load-bearing plate 4 is used to prevent the screen 7 from falling off the frame 2. The screening mechanism selects a corresponding number of screens 7 according to the degree of screening of chips, and installs them on the frame 1 from top to bottom. The mesh diameter of the screen 7 decreases from top to bottom to facilitate the classification of chips. In order to facilitate the rapid classification of chips, the frame 2 is controlled to rotate around the rotating shaft 5 by the knob 6, so that the screen 7 on the frame 2 forms a horizontal angle with the ground. The chips on the screen 7 roll along the screen 7 under the action of gravity, and the chips smaller than the mesh size fall from the mesh into the next layer of screen 7 for repeated screening. The larger the horizontal angle, the faster the screening speed. The vibrator 8 pushes and pulls the interlocking frame 3 to make the screen 7 reciprocate in the frame 2, avoiding the accumulation of chips and clogging the mesh while further accelerating the classification of chips.

[0027] See also Figure 1 and Figure 2 As shown, the chimeric frame 3 includes a positioning hole 31, a guide rod 32 and a connecting hole 33. The positioning hole 31 is arranged on both sides of the frame 2, the guide rod 32 is installed on one side of the chimeric frame 3 and is slidably connected to the positioning hole 31, and the connecting hole 33 is arranged at the center of the chimeric frame 3 and is connected to the vibrator 8.

[0028] The positioning hole 31 is used to install the guide rod 32. The guide rods 32 on both sides slide in the positioning hole 31 to ensure that the mosaic frame 3 and the frame 2 will not separate, thereby limiting the movement space of the screen 7 and preventing the screen 7 from falling during vibration. The connecting hole 33 is used to transmit the power of the vibrator 8. Each connecting hole 33 of the mosaic frame 3 is also connected to the vibrator 8 to facilitate synchronous vibration and reduce energy consumption.

[0029] See also Figure 1 to Figure 4 As shown, the load-bearing plate 4 includes a groove 41 and rollers 42 . The groove 41 is arranged on the upper surface of the load-bearing plate 4 , and the rollers 42 are arranged in an array in the groove 41 .

[0030] The groove 41 is used to install the roller 42. Since most of the weight of the screen 7 is concentrated on the load-bearing plate 4 and the screen 7 reciprocates between the embedded frame 3 and the frame 2, the severe friction will accelerate the wear of the load-bearing plate 4 and the screen 7. The roller 42 is used to reduce the friction to increase the service life of both.

[0031] See also Figure 1 to Figure 3 As shown, the screen 7 includes a mounting frame 71, a support rod 72, a telescopic rod 73 and a spring 74. The mounting frame 71 is arranged on the outside of the screen 7, the support rod 72 is arranged in the mounting frame 71, one end of the telescopic rod 73 is connected to the mounting frame 71, and the other end is connected to the frame 2, and the spring 74 is surrounded on the outside of the telescopic rod 73.

[0032] The mounting frame 71 is used for initially fixing the screen 7 and facilitating the quick replacement and maintenance of the screen 7. The support rod 72 is used to prevent the mounting frame 71 from being deformed during rapid vibration and to provide a fulcrum for the connection between the load-bearing plate 4 and the screen 7. The spring 74 provides the mounting frame 71 with a reset capability and cooperates with the vibrator 8 to achieve the purpose of rapid oscillation and blanking. The telescopic rod 73 acts as a damper to prevent the mounting frame 71 from being damaged due to the rapid expansion and contraction of the spring 74.

[0033] See also Figure 1 to Figure 5 As shown, the vibrator 8 includes a push rod 81, a gear set 82, a connecting rod 83 and a motor 84. The push rod 81 is connected to one side of the interlocking frame 3 and is slidably set on the top of the vibrator 8. One end of the connecting rod 83 is rotatably connected to the bottom of the push rod 81, and the other end is rotatably connected to the gear set 82. The motor 84 is coaxially connected to the gear set 82.

[0034] The push rod 81 is simultaneously connected to the connection holes 33 on all the interlocking frames 3 to facilitate synchronous vibration. The motor 84 serves as a power source to drive the transmission of the gear set 82. The gear set 82, the push rod 81 and the connecting rod 83 form a crank-connecting rod device, so that the push rod 81 continuously squeezes the interlocking frame 3 to drive the screen 7 to vibrate.

[0035] See also Figure 1 to Figure 6 As shown, a chip waste collection device for a milling machine includes a collecting trough 9, a recovery box 10, a column 11 and the multi-volume chip screening mechanism mentioned above. The collecting trough 9 is arranged directly below the frame 2, the columns 11 are arranged at the notches on both sides of the collecting trough 9, and the recovery box 10 is slidably arranged on the columns 11 and close to the end face of the frame 2.

[0036] The column 11 is used to install the recovery box 10 and adjust the height of the recovery box 10 so that the recovery box 10 is always aligned with the inclined bottom end of the screen 7. The collection trough 9 is used to recover the chips with the smallest particle size. The chips that do not pass through the screen 7 fall into the recovery box 10 under the action of gravity and are centrally processed.

[0037] See also Figure 6 As shown, the recovery box 10 includes an inclined plate 101, an inlet 102 and a through hole 103. The inlet 102 is arranged on one side of the top of the recovery box 10, the inclined plate 101 is arranged in the inlet 102, and the through hole 103 is arranged on both sides of the recovery box 10.

[0038] The feed port 102 is used to load the chips on the screen 7. The inclined plate 101 is used to prevent the side wall of the recovery box 10 from hindering the chips from falling. The size of the through hole 103 is the same as the size of the column 11. Since the inclination of the screen 7 will change with the frame 2, the height of the recovery box 10 on the column 11 is adjusted to ensure that the chips on the screen 7 can completely enter the recovery box 10.

[0039] See also Figure 6As shown, the column 11 includes a slot 111 , a latch 112 and a pull ring 113 . The slot 111 is arranged in an array on the column 11 . The latch 112 passes through the slot 111 to lift the recycling box 10 . The pull ring 113 is arranged at one end of the latch 112 .

[0040] The engagement of the card slot 111 and the latch 112 lifts the entire recycling box 10 , and the fast adjustment of the height of the recycling box 10 can be facilitated by installing and removing the latch 112 through the pull ring 113 .

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
