[0032] Example 1

[0033] Reference Figure 1-8 , which is the first embodiment of the present invention, provides a screening and gathering device for chip loading, including a screening component 100, a gathering component 200 and an adjustment component 300.

[0034] In this embodiment, the screening assembly 100 includes a bracket 101, a driving motor 102 arranged on the bracket 101, a rotating rod 103 connected to the driving motor 102, a rotating block 104 sleeved on the rotating rod 103, an embedded disk 105 connected to the rotating block 104, and a threaded rod 106 connected to the embedded disk 105.

[0035] Furthermore, the present invention also includes a folding assembly 200, which is arranged on the bracket 101, including support rods 201 symmetrically arranged at the upper and lower ends of the rotating block 104, rollers 202 arranged at the ends of the support rods 201, elastic members 203 arranged between the support rods 201, and a tightening block 204 arranged on the end of the support rod 201 away from the roller 202.

[0036] Furthermore, the present invention also includes an adjustment component 300, which is symmetrically arranged on both sides of the tightening block 204, including a mounting seat 301, a driving rod 302 rotatably arranged in the mounting seat 301, a through hole 303 opened on the driving rod 302, a cross bar 304 passing through the driving rod 302, a rotating frame 305 fixedly connected to the cross bar 304, a sliding rod 306 slidably connected to the mounting seat 301, a return spring 307 sleeved on the outside of the sliding rod 306, and a limiting rod 308 fixedly connected to the sliding rod 306.

[0037] Furthermore, the output shaft of the driving motor 102 is fixedly connected to the rotating rod 103, and the rotating rod 103 is also rotatably connected to the bracket 101. The side wall of the rotating rod 103 is symmetrically provided with strip grooves 103a, and the inner wall of the rotating block 104 is symmetrically provided with strip grooves 104a. The strip grooves 103a are embedded in the strip grooves 104a. The rotating block 104 is also provided with an embedding groove 104b, and the rotating block 104 is generally in the shape of a conical boss.

[0038] Furthermore, the embedded disk 105 is disposed in the embedded groove 104 b , and the threaded rod 106 is also connected to the bracket 101 through threads, and a rotating disk 106 a is disposed at the end of the threaded rod 106 .

[0039] Furthermore, a feeding auxiliary component 107 is provided between the screening component 100 and the gathering component 200.

[0040] In this embodiment, the feeding auxiliary component 107 includes two symmetrically arranged feeding barrels 107a, a feeding tube 107b arranged in the feeding barrel 107a, and a bendable clamp 107c detachably arranged at the end of the feeding barrel 107a, and a feeding channel 107d is provided on the bendable clamp 107c.

[0041] Furthermore, the support rod 201 is rotatably connected to the bracket 101, and a protrusion 201a is also provided on the support rod 201. The roller 202 is rotatably provided on the support rod 201, and the roller 202 is in contact with the surface of the rotating block 104. The elastic member 203 connects the two support rods through the protrusion 201a, and the protrusion 201a is provided on the same side as the roller 202. The tightening block 204 is provided with an arc-shaped notch 204a.

[0042] Furthermore, the driving rod 302 is cylindrical, and through holes 303 are evenly opened on the side wall of the driving rod 302 in a circumferential manner. The cross bar 304 is arranged on the rod portion of the driving rod 302. The rotating frame 305 includes a rotating shaft 305a and a supporting frame 305b. The rotating shaft 305a is sleeved on the outside of the driving rod 302, and the rotating shaft 305a is arranged between the mounting seats 301. The rotating shaft 305a is fixed to the cross bar 304.

[0043] Preferably, the feed pipe 107b is carried on the support frame 305b, and two support frames 305b are arranged, one long and one short.

[0044] Preferably, the roller 202 can be set at the smaller end of the rotating block 104 each time the crimping is performed, and the rotating block 104 is gradually moved to slowly reduce the extrusion opening of the tightening block 204 .

[0045] Operation process: pass the ends of the two feeding tubes 107b through the bendable clamp 107c, and the bendable clamp 107c is hung between the tightening blocks 204. In order to drive the tightening blocks 204 to tighten, start the driving motor 102. The driving motor 102 can drive the rotating rod 103 to rotate. Since the strip groove 103a on the rotating rod 103 is embedded in the strip groove 104a on the rotating block 104, the rotation of the rotating rod 103 can drive the rotating block 104 to rotate synchronously. Since the side wall of the rotating block 104 is approximately the same as the side wall of the cuboid, during the rotation of the rotating block 104, the roller 202 will not rotate due to the different thicknesses on the vertical section of the rotating block 104. In order to make the roller 202 fit tightly against the side wall of the rotating block 104, a protrusion 201a is set on the support rod 201, and an elastic member 203 is connected between the protrusions 201a. Through the contraction force of the elastic member 203, one side of the roller 202 of the two support rods 201 is tightened, so that the roller 202 is always in contact with the rotating block 104. The support rod 201 is rotatably connected to the bracket 101. When one side of the roller 202 is expanded and contracted due to the rotation of the rotating block 104, the tightening block 204 on the other side will contract and expand due to the lever principle, that is, the end of the feeding tube 107b in the bendable clamp 107c between the tightening blocks 204 is brought closer.

[0046] In order to prevent the arc-shaped notch 204a on the tightening block 204 from excessively squeezing the bendable clamp 107c and causing damage to the feed pipe, the staff can rotate the turntable 106a. Since the threaded rod 106 connected to the turntable 106a and the bracket 101 are threadedly connected, turning the turntable 106a can make the threaded rod 106 extend toward the drive motor 102. An embedded disk 105 is also fixed on the threaded rod 106, that is, the embedded disk 105 extends in this direction. The embedded disk 105 is in the embedded groove 104b, and the threaded rod 106 can push the rotating block 104 through the embedded disk 105.

[0047] Since the rotating block 104 has a linear strip groove 104a, the rotating block 104 will move along the rotating rod 103 when it is pushed, but it will not affect its own rotation due to the driving motor 102, that is, the threaded rod 106 can push the rotating block 104 when the rotating block 104 rotates, so that it moves on the rotating rod 103. Since the rotating block 104 is in the shape of a conical boss, when the rotating block 104 moves, the thickness of the rotating block 104 on the vertical plane where the roller 202 is located continues to increase, and the direct result is that the roller 202 is expanded to a greater extent due to the rotation of the rotating block 104, that is, the maximum distance between the rollers 202 is increased. According to the principle of leverage, the space squeezed by the tightening block 204 at the other end is smaller. The above scheme can control the squeezing degree of the arc-shaped notch 204a, and the docking degree of the two feeding pipes 107b can be timely controlled to prevent excessive squeezing of the bendable clamp 107c.

[0048] When the ends of the two feed tubes 107b are close to each other, the chip material in the feed tube 107b will be concentrated at the end position of the feed tube 107b, and a discharge port is opened at the end position of the feed tube 107b, and the discharge port is also opened on the bendable clamp 107c, so that the chips will overflow from the discharge port one by one when feeding.

[0049] Through this device, two feed tubes 107b are placed on the rotating frame 305, and the top height of the rotating frame 305 is adjusted so that the front end of the feed tube 107b can be pre-inserted into the bendable clamp 107c. The bendable clamp 107c is retracted by driving the motor 102. The rotating disk 106a can control the distance of the tightening block during extrusion to adapt to different degrees of retraction.

[0050] Example 2

[0051] Reference Figure 1-11 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0052] Furthermore, two vertical rods 306a are provided on the slide rod 306. The vertical rod 306a passes through the mounting seat 301 and is symmetrically arranged on both sides of the driving rod 302. The vertical rod 306a is slidably connected to the mounting seat 301, and a pressure plate 306b is fixedly connected to the end of the vertical rod 306a.

[0053] Preferably, the return spring 307 is sleeved outside the vertical rod 306a, one end of the return spring 307 is connected to the top of the mounting seat 301, and the other end is connected to the bottom of the pressing plate 306b.

[0054] Furthermore, the limiting rod 308 is fixedly disposed at the center of the bottom pressure plate 306 b , the limiting rod 308 passes through the mounting seat 301 and is slidably connected to the mounting seat 301 , and the limiting rod 308 can be embedded in the through hole 303 .

[0055] The rest of the structure is the same as that of Example 1.

[0056] Operation process: In order to set up two feed pipes, adjustment components 300 are set on both sides of the tightening block 204. When the end of the feed pipe 107b is set on the support frame 305b, the two support frames 105b are preferably set as one high and one low, so that one end of the feed pipe 107b can extend under the bendable clamp 107c, and the other feed pipe 107b can extend above the bendable clamp 107c. When the height needs to be adjusted, the height of the support frame 305b needs to be lowered or raised.

[0057] Taking the adjustment assembly 300 on one side as an example, the adjustment assembly 300 on the other side has the same principle, and the only difference is the height of the support frame 305b, which will not be repeated here; the pressure plate 306b at the top of the vertical rod 306a is pressed down, and the return spring 307 is squeezed at the same time, and the pressure plate 306b at the top of the vertical rod 306a sinks, driving the limit rod 308 to move downward and exit the through hole 303. At this time, the rotating shaft 305a can be rotated. Since the rotating shaft 305a is connected to the driving rod 302 through the cross bar 304, the rotating shaft 305a can rotate synchronously with the driving rod 302 to support When the frame 305b is rotated to an appropriate vertical height, since a number of through holes 303 are opened in the driving rod 302, the more through holes 303 there are, the more adjustable height levels there are; at this time, the pressure plate 306b is released, and the reset spring 307 pops up, so that the bottom limit rod 308 is reinserted into the through hole 303, and the limit rod 308 fixes the driving rod 302 so that it cannot rotate, and the rotating frame 305 completes the positioning and remains unchanged, and the feed pipe 107b is rotated and connected to the top of the support frame 305b to complete the placement of the feed pipe 107b, and the subsequent process is the same as that in Example 1.

[0058] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
