Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a screening mechanism of a knitted fabric scrap recycling machine. Background Art

[0002] Knitted fabrics are made by knitting needles by bending yarn into loops and then interlacing them. Knitted fabric production produces a lot of scraps, which would be a waste of resources if simply discarded. Therefore, recycling these scraps can save production costs.

[0003] Since the scraps generated during the processing of knitted fabrics are of different lengths, and the existing knitted fabric waste recycling machines are difficult to separate the scraps of different lengths, the longer scraps will easily get entangled on the crushing blades during the subsequent crushing process, affecting the crushing effect and causing the crushing equipment to malfunction. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a screening mechanism for a knitted fabric scrap recycling machine to solve the problem that it is difficult to screen knitted fabric scraps of different lengths, which affects the subsequent crushing effect.

[0005] Based on the above purpose, the utility model provides a screening mechanism of a knitted fabric scrap recycling machine, comprising a base and a separating and unloading portion provided on the base, wherein the separating and unloading portion is used to separate and unload waste materials of different lengths, and the separating and unloading portion comprises:

[0006] A separation ring is fixed to the top of the base.

[0007] A shell is fixed on the top of the separation ring, and a plurality of external feeding openings are circumferentially provided between the shell and the separation ring.

[0008] A support column is fixed to the bottom of the separation ring, and a plurality of inner feeding openings are circumferentially provided between the support column and the separation ring.

[0009] The screening mechanism of the knitted fabric scrap recycling machine also includes:

[0010] A main shaft disposed between the top of the support column and the top of the interior of the housing is rotated.

[0011] A driving member for driving the main shaft to rotate.

[0012] A separation disc is fixed on the main shaft.

[0013] A plurality of movable rods are circumferentially hinged to the outside of the separation disc.

[0014] The adjusting part is used to drive the free end of the movable rod to deflect up and down. When the separation disk rotates, the adjusting part lifts the free end of the movable rod to a certain deflection angle, so that several movable rods and the separation disk are combined to form a cage-shaped screening area.

[0015] Preferably, the cross section of the separation ring is in a herringbone shape, and the top of the separation ring is lower than the bottom of the separation disc.

[0016] Preferably, the top of the separation ring is located between the outer shell and the separation disc in the radial direction thereof, and the bottom of the separation ring is located between the outer shell and the support column.

[0017] Preferably, the outer feed opening is located at the intersection of the bottom edge of the shell and the bottom edge of the separation ring.

[0018] Preferably, the adjustment part includes a bottom tray vertically slidably mounted on the main shaft, a plurality of support bars are fixedly mounted on the outside of the bottom tray, one end of the support bar is slidably mounted on a guide groove provided at the bottom of the movable rod, and a first telescopic cylinder is provided on the outside of the main shaft for pushing the bottom tray to slide up and down.

[0019] Preferably, the adjustment portion further includes a plurality of guide bars arranged outside the main shaft, one end of the guide bar passes through a spline hole provided on the bottom tray, and the guide bar and the spline hole cooperate to limit the circumferential freedom of the bottom tray.

[0020] Preferably, the first telescopic cylinder is located between the bottom tray and the support column, and the bottom tray is located between the first telescopic cylinder and the separation plate.

[0021] Preferably, the screening mechanism of the knitted fabric scrap recycling machine further comprises:

[0022] A feed hopper is fixed to the top of the shell.

[0023] A feeding slide is hinged to one side of the feed hopper.

[0024] A lifting portion is used to drive the free end of the feeding slide to deflect.

[0025] The beneficial effects of the present invention are as follows: the present invention manipulates the adjusting part to make the free end of the movable rod tilt upward at a certain angle, and while the driving part drives the main shaft to rotate, the main shaft will drive several movable rods to rotate synchronously, so that a semi-closed screening area can be formed, and the knitted fabric waste falling on the separation disk moves radially along the separation disk under the action of centrifugal force. The knitted fabric waste with longer length will be suspended on the movable rod under the action of centrifugal force, and the knitted fabric waste with shorter length will fall to the inner oblique ring from the gap between the two adjacent movable rods. After the main shaft has been running for a certain time, the driving part is turned off, and the adjusting part is manipulated to make the free end of the movable rod deflect downward until its free end is a certain distance lower than the top of the separation disk, and the longer knitted fabric waste hanging on the movable rod will slide to the outer oblique ring, so that the knitted fabric waste of different lengths can be roughly screened out.

[0034] like Figures 1 to 3 As shown, a screening mechanism of a knitted fabric scrap recycling machine includes a base 1 and a separating and unloading portion 2 provided on the base 1. The separating and unloading portion 2 is used to separate and unload scraps of different lengths. The separating and unloading portion 2 includes:

[0035] A separation ring 22 is fixed to the top of the base 1 .

[0036] The outer shell 21 is fixed on the top of the separation ring 22 , and a plurality of outer discharge openings 23 are circumferentially provided between the outer shell 21 and the separation ring 22 .

[0037] A support column 25 is fixed to the bottom of the separation ring 22 , and a plurality of inner feed openings 24 are circumferentially provided between the support column 25 and the separation ring 22 .

[0038] The screening mechanism of the knitted fabric scrap recycling machine also includes:

[0039] The main shaft 4 disposed between the top of the support column 25 and the top of the interior of the housing 21 is rotated.

[0040] The driving member 5 is used to drive the main shaft 4 to rotate. The driving member 5 includes a helical gear fixed to the top of the main shaft 4 and a driving motor fixed to the top of the housing 21. The output end of the driving motor is also fixed with a helical gear, and the tooth surfaces of the two helical gears are meshed.

[0041] The separation disc 6 is fixed on the main shaft 4.

[0042] Several movable rods 7 are circumferentially hinged to the outside of the separation disc 6.

[0043] The adjusting portion 8 is used to drive the free end of the movable rod 7 to deflect up and down. When the separation disk 6 rotates, the adjusting portion 8 lifts the free end of the movable rod 7 to a certain deflection angle, so that several movable rods 7 and the separation disk 6 are surrounded to form a cage-shaped screening area.

[0044] like Figure 2 and Figure 3 As shown, the cross section of the separation ring 22 is in the shape of a herringbone, and the top of the separation ring 22 is lower than the bottom of the separation disc 6 .

[0045] The top of the separation ring 22 is located between the housing 21 and the separation disc 6 in the radial direction thereof, and the bottom of the separation ring 22 is located between the housing 21 and the support column 25 .

[0046] Such design enables the free end of the movable rod 7 to be deflected from a height below the bottom of the separation disc 6 to a height above the top of the separation disc 6. By manipulating the adjusting portion 8, the free ends of the movable rods 7 can be kept in a tilted state during the rotation of the separation disc 6. In this way, the waste entering the shell 21 can first fall on the top of the separation disc 6. Under the action of centrifugal force, waste of different lengths will move toward the boundary of the separation disc 6. Relatively long waste will be hung on the tilted movable rod 7, and short waste can fall from the interval area between two adjacent movable rods 7. In this way, knitted fabric waste within two specification ranges can be efficiently and roughly screened out. Before screening, collection boxes can be placed under the inner discharge port 24 and the outer discharge port 23 to facilitate the short knitted fabric waste to pass through the inner discharge port 24 and fall into the collection box. After the separation disk 6 has run for a period of time, the driving member 5 is turned off, and then the adjustment part 8 is manipulated to make the free end of the movable rod 7 deflect downward until its free end is a certain distance below the bottom of the separation disk 6. The longer waste hanging on the movable rod 7 slides toward the outer discharge port 23 and passes through the outer discharge port 23 and falls into the collection box. In this way, the knitted fabric waste can be roughly screened according to length and stored separately. This can prevent the longer waste from affecting the normal operation of the crusher in the subsequent crushing step.

[0047] like Figures 1 to 3 As shown, the outer discharge port 23 is located at the intersection of the bottom boundary of the outer shell 21 and the bottom boundary of the separation ring 22. With such a design, after the separation disc 6 is stopped, the adjustment part 8 can be manipulated to make the free end of the movable rod 7 deflect downward until its free end is in a downward tilted state, so that the longer waste hanging outside it can slide to the outer discharge port 23, so that the shorter waste and the longer waste can be separately contained, so that they can be crushed using different equipment later, thereby improving the overall crushing effect and efficiency.

[0048] like Figure 2 and Figure 3 As shown, the adjusting portion 8 includes a bottom tray 81 that is vertically slidably sleeved on the main shaft 4, and a plurality of support bars 85 are fixedly provided on the outside of the bottom tray 81. One end of the support bar 85 is slidably sleeved with a guide groove 86 provided at the bottom of the movable rod 7, and a first telescopic cylinder 84 is provided on the outside of the main shaft 4 for pushing the bottom tray 81 to slide up and down.

[0049] The adjustment portion 8 also includes a plurality of guide bars 83 provided outside the main shaft 4. One end of the guide bar 83 passes through a spline hole 82 provided on the bottom tray 81. The guide bar 83 and the spline hole 82 cooperate to limit the circumferential freedom of the bottom tray 81.

[0050] The first telescopic cylinder 84 is located between the bottom tray 81 and the support column 25 , and the bottom tray 81 is located between the first telescopic cylinder 84 and the separation tray 6 .

[0051] By controlling the extension of the first telescopic cylinder 84, its output end pushes up the bottom tray 81, and the bottom tray 81 drives the support bar 85 to rise synchronously. During this process, the support bar 85 slides in the guide groove 86 at the bottom of the movable rod 7 toward the free end of the movable rod 7, so that the free end of the movable rod 7 can be lifted up until its free end is higher than a certain height above the top of the separation disk 6. When the driving member 5 drives the main shaft 4 to rotate, the main shaft 4 can synchronously drive the separation disk 6, the movable rod 7 and the adjusting part 8 to rotate synchronously, and the free end of the movable rod 7 can be kept in a tilted state during the rotation of the separation disk 6, so that the movable rod 7 forms an annular interception surface, and the longer waste will be blocked under the action of centrifugal force. Hanging on the movable rod 7, the shorter waste will pass through between the two adjacent movable rods 7 under the action of centrifugal force, thereby realizing the length screening operation of the knitted fabric waste. After the separation disk 6 has run for a period of time, the driving part 5 is turned off, and then the adjustment part 8 is manipulated to make the free end of the movable rod 7 deflect downward until its free end is a certain distance lower than the bottom of the separation disk 6. The longer waste hanging on the movable rod 7 slides toward the external discharge port 23 and passes through the external discharge port 23 into the collection box. In this way, the waste can be divided into two specifications and contained separately, so that they can be crushed separately in the future. Different crushers are used for crushing operations to improve the effect and efficiency of subsequent waste crushing.

[0052] like Figures 1 to 3 As shown, the screening mechanism of the knitted fabric scrap recycling machine also includes:

[0053] The feed hopper 9 is fixed to the top of the shell 21.

[0054] A loading chute 10 is hinged to one side of the feed hopper 9.

[0055] The lifting part 3 is used to drive the deflection of the free end of the loading chute 10. The lifting part 3 includes a second telescopic cylinder vertically fixed to the outside of the shell 21 and a limiting cross bar laterally fixed to the output end of the second telescopic cylinder. The limiting cross bar is slidably connected to the slide groove provided at the bottom of the loading chute 10.

[0056] With such a design, since the separation disc 6 is used to separate several waste materials of different lengths, the feed hopper 9 is located at the top of the shell 21 near its top center, and the normal feeding operation is difficult and troublesome. By assuming a deflectable feeding chute 10, the waste to be screened can be put into the feeding chute 10 at the top boundary of the shell 21, and then the free end of the feeding chute 10 is lifted to a certain height by the lifting part 3, so that the waste in the feeding chute 10 automatically slides into the feed hopper 9 until it all falls into the shell 21 and can fall accurately on the separation disc 6. In this way, the screening operation can be carried out, reducing the difficulty of feeding.

[0057] Working principle: Before screening, collection boxes can be placed under the inner discharge port 24 and the outer discharge port 23. Before starting the driving member 5, the free ends of the movable rods 7 are made higher than a certain height from the top of the separation disc 6 by manipulating the adjusting portion 8, and the free ends of the movable rods 7 are kept in a tilted state during the rotation of the separation disc 6. Then, the knitted fabric waste of different lengths is put into the feeding chute 10, and then the lifting portion 3 is manipulated to lift the free end of the feeding chute 10, so that the waste in the feeding chute 10 slides into the feed hopper 9, and passes through the feed hoppers 9 and falls on the top of the separation disc 6. Under the action of centrifugal force, the waste of different lengths will move to the boundary of the separation disc 6, and the relatively long waste will hang on the tilted movable rods. On the rod 7, short waste can fall from the interval area between two adjacent movable rods 7, so that the knitted fabric waste within two specification ranges can be efficiently and roughly screened out, so that the short knitted fabric waste can pass through the inner discharge port 24 and fall into the collection box. After the separation disk 6 has run for a period of time, the driving member 5 is turned off, and then the adjustment part 8 is manipulated to make the free end of the movable rod 7 deflect downward until its free end is a certain distance below the bottom of the separation disk 6. The longer waste hanging on the movable rod 7 slides toward the outer discharge port 23 and passes through the outer discharge port 23 and falls into the collection box. In this way, the knitted fabric waste can be roughly screened out according to length and divided into containers, so that the longer waste can be prevented from affecting the normal operation of the crusher in the subsequent crushing step.
