Background
The recycling value of the waste plastic bottles lies in that plastic materials (such as PET, PE and the like) can be recycled, the physical performance can reach more than 90%, the plastic bottles generally need to be classified firstly aiming at recycling of the plastic bottles, and the plastic bottles are classified to be cleaned, subjected to label removal, crushed, sorted and other processing procedures to be recycled, and for plastic bottle slitting equipment, the plastic bottles are cut randomly to increase the stacking density, so that the subsequent packaging and transportation are facilitated.
Although the plastic bottles generally can be classified by simple specifications, the bottle body state of each type of plastic bottles is complex when the plastic bottles are supplied, bending and folding phenomena can exist, the plastic bottles are folded and extruded easily in the flattening process, the plastic bottles are not completely flattened after being flattened, the cutting effect of the plastic bottles which are folded and flattened in the subsequent slitting process is poor, so that a lot of cut crushed materials and fragments exist when the plastic bottles are cut under the folding state, the shapes of the cut plastic strips are irregular and the like, complete bottle caps, bottle neck rings and the like are also arranged in the slitting process, the irregular slit plastic crushed materials are mixed with the bottle caps, the bottle neck rings and other crushed material bodies together too much, and the slit materials are not beneficial to subsequent further screening, cleaning and collecting.
Disclosure of Invention
The invention aims to solve the problems of poor slitting effect, such as serious folding of plastic strips, more plastic fragments, irregular strip shapes and the like, in slitting of the conventional plastic bottles, and provides a plastic bottle directional regular slitting device. The waste plastic bottles are fully flattened and flattened, and are subjected to longitudinal directional and regular slitting, the plastic strips are regular in shape and free of irregular fragments, subsequent impurities can be conveniently screened and removed from the regular plastic strips, and the overall recovery efficiency is improved.
In order to solve the technical problems, the invention adopts the technical scheme that:
a directional regular slitting equipment for plastic bottles comprises a differential shaping roller assembly, an extrusion feeding roller assembly and a cutting roller assembly which are sequentially arranged in the advancing direction of the plastic bottles:
the differential shaping roller assembly comprises a first driving roller, a first driven roller, a second driving roller and a second driven roller, wherein the axes of the first driving roller, the first driven roller, the second driven roller and the second driven roller are mutually parallel and are distributed in a rectangular array, the first driving roller and the first driven roller are arranged up and down, the shaft ends of the first driving roller and the first driven roller are in differential transmission through a first belt, the second driving roller and the second driven roller are arranged up and down, the shaft ends of the second driving roller and the second driven roller are in differential transmission through a second belt, the rotating directions of the first belt and the second belt are opposite, the transmission ratio is the same, a gap between the first driven roller and the second driving roller is a first passing gap, a gap between the first driving roller and the second driven roller is a second passing gap, the gap between the first passing gap and the second passing gap are the same, and the feeding end of a plastic bottle is arranged above the first passing gap;
the extrusion feeding roller assembly comprises a third driving roller and a third driven roller, the axes of the third driving roller and the third driven roller are parallel to each other and are arranged on the left and the right, the shaft ends of the third driving roller and the third driven roller are driven by gears and rotate oppositely, and a gap between the third driving roller and the third driven roller is a third through gap; the distance between the third through gaps is smaller than that of the second through gaps;
the cutting roller assembly comprises a fixed cutter plate and a movable cutter roller, the fixed cutter plate is vertically arranged, the movable cutter roller is arranged on one side of the fixed cutter plate, a cutting channel for the engagement of the cutting edge of the movable cutter roller and the cutting of the fixed cutter plate is realized, and the discharge end of the plastic bottle is arranged below the fixed cutter plate and the movable cutter roller;
the discharge hopper is arranged between the third through gap and the cutting roller assembly, the opening of the discharge hopper is large, the outlet is small, and the maximum width of the outlet of the discharge hopper is smaller than the length of the bottle body of the plastic bottle;
the device also comprises a first driving device, a second driving device, a third driving device and a fourth driving device which are respectively connected with the first driving roller, the second driving roller, the third driving roller and the movable knife roller.
It should be noted that most of the existing recycled plastic bottles deform and fold during transportation, and the invention realizes the flattening and further flattening of the shape of the folded and deformed plastic bottles through different differential shaping roller assemblies and extrusion roller assemblies passing through gaps, and the specific implementation mode is as follows: the plastic bottles can be taken into and pass through the second passing clearance in the same way under the action of different traction friction forces due to the fact that the positions of the first driving roller and the second driven roller are opposite, if folding deformation exists, the plastic bottles can be gradually unfolded in the differential traction process and are flattened to a certain degree; the plastic bottle after being unfolded enters a third passing gap which is smaller than the second passing gap, because the plastic bottle is unfolded and flattened to a certain degree in the previous step, when the plastic bottle enters the third passing gap with smaller gap, the plastic bottle is more easily rolled into the third passing gap by the opposite rotation of a third driving roller and a third driven roller, and after passing through the third passing gap, the plastic bottle is fully flattened, so that better cutting conditions are provided for the next step of strip cutting; the crushed plastic bottles fall into the discharging hopper under the forced feeding action of the extrusion feeding roller assembly, and the plastic bottles in the discharging hopper are kept under certain pressure by the movement of the feeding roller assembly so as to realize continuous and uniform feeding. The maximum width of the blanking hopper is smaller than the length of the bottle body of the plastic bottle, so that the longitudinal plastic bottle can still keep longitudinal feeding when falling into the cutting roller assembly, the cutting direction is the length direction of the plastic bottle, the cutting on the fixed cutter plate is meshed with the cutting edge of the movable cutter roller to realize cutting, the plastic bottle is cut into plastic strips with almost the width, and the plastic strips fall out from the discharge end and can be transferred to the next procedure.
The plastic bottle flattening machine disclosed by the invention is used for flattening and flattening the plastic bottle in the whole process, and then fully flattening the plastic bottle, compared with the traditional one-step flattening process, the plastic bottle can be fully flattened and flattened, fully flattened, uniformly distributed under pressure and longitudinally descended at a constant speed, so that a good regular cutting condition is created for a cutting process. The cutting unit is used for longitudinally and regularly cutting the waste plastic bottles into strips, the plastic strips are kept at a certain width, the bottle caps and the bottleneck rings are all cut, and the cut plastic bottle strips are not folded and are not irregularly cut into strips and crushed materials; meanwhile, other non-bottle type domestic waste plastic products are fragile due to size difference, materials and the like, the difference between the cut longitudinal geometric dimension and the cut strip of the waste plastic bottle is too large, and non-bottle type impurities can be completely separated by simple screening. The invention improves the slitting quality of the plastic bottles and is suitable for flattening and flattening operation of more complicated plastic bottles.
Furthermore, the first driving roller and the second driving roller are circular rollers, the first driven roller and the second driven roller are quincunx roller shafts with notches on the surfaces, the rotating speed of the first driving roller is higher than that of the first driven roller, the rotating speed of the second driving roller is higher than that of the second driven roller, and the notches on the surfaces of the first driven roller and the second driven roller are larger than the bottle cap size of a plastic bottle.
Furthermore, the surfaces of the first driving roller and the second driving roller are rough, and the surfaces of the first driven roller and the second driven roller are smooth.
It should be noted that, the rough surface effect of first drive roll and second drive roll is to rubbing the surface of plastic bottle, get rid of the label, not hard up the surface dirt, simultaneously to the waste plastic bottle that the surface that the minority caused because of the packing process curls, form friction draft roller set differential motion with first driven voller and second driven voller respectively, circular roller surface is rough, the functioning speed is fast, frictional force is big, plum blossom type roller surface is level and smooth, frictional force is little, bottleneck position can be with the accurate traction of plastic bottle and move to the direction of rotation under the effect of the surperficial notch joint of plum blossom type roller, the protruding cambered surface of plum blossom type roller carries out preliminary flattening and tensile to the plastic bottle body, two sets of roller set up opposite direction, can make the two-sided friction that receives of plastic bottle, reach better friction and traction effect.
Furthermore, the third driving roller and the third driven roller are both plum blossom-shaped roller shafts with notches on the surfaces, and the notches of the third driving roller and the third driven roller are opposite when the third driving roller and the third driven roller rotate oppositely to a third passing gap.
Furthermore, the clearance between two notches when the surface notches of the third driving roller and the third driven roller face each other is larger than the size of the bottle cap of the plastic bottle, and the arc surface length between two adjacent notches of the third driving roller and the third driven roller is matched with the length of the bottle body of the plastic bottle.
It should be noted that since the cap can be much harder than the body, extruding the cap and body to the same thickness can be problematic for the extrusion feed roller assembly: if the bottle cap is to be flattened, the distance between the third through gaps can only be increased, and the distance between the third through gaps is too large, the flattening effect on the bottle body is not ideal, the subsequent slitting effect on the bottle body is influenced, if the flattening effect of the bottle body is to be ensured, the distance between the third through gaps needs to be controlled within a smaller range, and the bottle cap is possibly clamped between rollers due to the fact that the bottle cap is hard and the rollers lose conveying capacity, so that the equipment is clamped; therefore, the surface notches of the quincunx roller shafts can meet the requirement for passing of the bottle caps, the roll surface intervals outside the surface notches can also guarantee the extrusion effect of the bottle bodies, the clamping failure is not easy to occur, and the flattening effect is excellent. Therefore, the waste plastic bottles which are vertically arranged fall into the concave hole of the feeding roller in a mode that the bottle openings are downward or the bottle bottoms are downward, the length of the cambered surface between every two adjacent notches is approximately equal to the length of the plastic bottles, if the bottle openings are downward, the roller set feeds in a pulling mode, and if the bottle openings are upward, the roller set feeds in a friction and pushing mode.
Furthermore, the device also comprises a flow dividing mechanism arranged between the second passing gap and the third passing gap.
Furthermore, the shunting mechanism is a shunting cavity which is hollow inside and has two ends in a herringbone symmetrical structure, the side walls of the two sides of the herringbone symmetrical structure are in smooth transition, and the top ends of the herringbone symmetrical structure at the two ends of the shunting cavity respectively face to the middle parts of the second passing gap and the third passing gap. The herringbone symmetrical structure of the scheme also has the function of randomly distributing the plastic bottles to the left side and the right side of the extrusion feeding roller assembly, and the herringbone symmetrical structure is also arranged at the lower end, so that the plastic bottles can be more accurately ensured to longitudinally enter the cutting roller assembly in the posture of a bottle mouth or a bottle bottom in the advancing process.
Further, the movable cutter roller comprises a plurality of groups of tooth-shaped cutting cutter wheels which are coaxially arranged at equal intervals, and the width between every two adjacent tooth-shaped cutting cutter wheels is larger than 1/4 of the longitudinal unfolding bottle width of the plastic bottle to be cut and smaller than 1/3 of the longitudinal unfolding bottle width of the plastic bottle to be cut.
It should be noted that the distance between two adjacent toothed cutting knife wheels is reasonably set, so that the width between two adjacent toothed cutting knife wheels is greater than 1/4 of the longitudinal unfolded bottle width of the plastic bottle to be cut and less than 1/3 of the longitudinal unfolded bottle width of the plastic bottle to be cut, and thus the plastic bottle can be cut by at least four knives by the toothed cutting knife wheels within the unfolding width when being cut, the width of the cut plastic strips is within a certain range and has small difference, the shapes and the widths of the cut plastic strips are regular and uniform, for example, the most common plastic bottles with the medium and small sizes from 250ml to 550ml on the market at present are about 13cm-23cm in length of the bottle body, the width of the unfolded bottle is about 6cm-9cm, after being cut, the width range is about 2cm-3cm, the width size is proper, and the subsequent screening of other impurities is facilitated, and the subsequent cleaning, packaging and collection are facilitated.
Furthermore, one side of the fixed cutter plate, which is back to the movable cutter roller, is also provided with an elastic force maintaining wheel set with the axis parallel to the axis of the movable cutter roller and a fifth driving device connected with the elastic force maintaining wheel set, and the elastic force maintaining wheel set and the movable cutter roller rotate oppositely at the same rotating speed;
the elastic force maintaining wheel set comprises a plurality of elastic force wheels which are coaxially arranged at equal intervals, the elastic force wheels and the tooth-shaped cutting knife wheels are alternately arranged, a through channel for the plurality of elastic force wheels to penetrate is arranged on the fixed knife plate, each elastic force wheel comprises a flexible wheel face and a rigid wheel shaft, and elastic supporting pieces are uniformly arranged between the rigid wheel shaft and the flexible wheel face.
It should be noted that, the elastic force maintaining wheel set is driven by the fifth driving device, the flexible wheel surface can simultaneously have a certain pressure on the bottle body and the bottle neck under the elastic force support of the elastic supporting member, the bottle does not shake left and right during cutting under the pressure, meanwhile, the pressure acts on the bottle body to generate friction force, under the friction force, the plurality of elastic wheels also drive the bottle body to slide downwards at a constant speed when rotating, the plurality of elastic wheels are alternately arranged between the tooth-shaped cutting knife wheels, and the contact surface is multipoint (for example, one side of the flattened bottle body can be cut by two cutting blades, namely, the contact point has two points, and the contact point of the plurality of elastic wheels 402 also has two points on one side of the flattened bottle body), so as to ensure that the bottle body does not shake left and right, and simultaneously, the flexible wheel surface can also stably act and move downwards.
It should be noted that, there are two kinds of crisscross grids on the fixed knife board, one kind is the cutting channel for the blade of the moving knife roller to engage and realize cutting, the opening of the cutting channel can be set to the hard alloy sharp right angle with higher intensity, it and the blade of several groups of tooth-type cutting knife wheels form the strong shearing stress in the slit, this stress is far greater than the physical property of the PET/PE bottle body/bottleneck of shearing-resistant cutting deformation, make the bottle body/bottleneck be easily mechanically cut and cracked, the cutting channel can be set as the through hole shape or can be set as the trough shape that can't pass through; the other type is a channel for the flexible wheel surfaces of a plurality of elastic wheels to pass through and contact with the plastic bottle, and the opening of the channel does not need alloy treatment and only needs to ensure that the flexible wheel surfaces normally pass through and do not influence rotation; in the mechanical cutting process, the speed of the elastic wheels is basically consistent with that of the tooth-shaped cutting knife wheels, so that the gap distance between the cutting teeth of the tooth-shaped cutting knife wheels is basically consistent with the vertical downward moving distance of the bottle body, namely, the cutting length of each knife tooth is uniform and orderly, and the phenomena of multiple cutting, chopping, beveling, missing cutting and the like are prevented.
Further, an arc-shaped support bottom is arranged below the fixed cutter plate, and one end of the arc-shaped support bottom is tangent to the periphery of the movable cutter roller. The arc-shaped support bottom can prevent the waste plastic bottle which is not completely cut from dropping off, and the plastic bottle is ensured to be fully cut off.
Compared with the prior art, the invention has the beneficial effects that:
the plastic bottle flattening and flattening device disclosed by the invention is used for flattening and flattening the plastic bottle in the whole process, and then fully flattening the plastic bottle. The cutting unit is used for longitudinally and regularly cutting the waste plastic bottles into strips, the plastic strips are kept at a certain width, the bottle caps and the bottleneck rings are all cut, and the cut plastic bottle strips are not folded and are not irregularly cut into strips and crushed materials; meanwhile, other non-bottle type domestic waste plastic products are fragile due to size difference, materials and the like, the difference between the cut longitudinal geometric dimension and the cut strip of the waste plastic bottle is too large, and non-bottle type impurities can be completely separated by simple screening. The invention improves the slitting quality of the plastic bottles and is suitable for flattening and flattening operation of more complicated plastic bottles.

The cutting unit is used for longitudinally and regularly cutting the waste plastic bottles into strips, the plastic strips are kept at a certain width, the bottle caps and the bottleneck rings are all cut, and the cut plastic bottle strips are not folded and are not irregularly cut into strips and crushed materials; meanwhile, due to the reasons of size difference, fragile material and the like, the longitudinal geometric size of other non-bottle type domestic waste plastic products after cutting is too large different from the cutting strip of the waste plastic bottle, and non-bottle type impurities can be completely separated by simple screening.
In this embodiment, the first driving roller 11 and the second driving roller 13 are circular rollers, the first driven roller 12 and the second driven roller 14 are quincunx roller shafts with notches on surfaces, the rotation speed of the first driving roller 11 is greater than that of the first driven roller 12, the rotation speed of the second driving roller 13 is greater than that of the second driven roller 14, and the notches on the surfaces of the first driven roller 12 and the second driven roller 14 are greater than the size of the bottle cap of the plastic bottle.
In the present embodiment, the surfaces of the first drive roller 11 and the second drive roller 13 are rough, and the surfaces of the first driven roller 12 and the second driven roller 14 are smooth.
It should be noted that the rough surfaces of the first driving roller 11 and the second driving roller 13 are used for rubbing the surface of the plastic bottle to remove labels and loosen surface dirt, and meanwhile, the waste plastic bottle with a curled surface caused by the packaging process is subjected to drafting shaping, and the waste plastic bottle and the first driven roller 12 and the second driven roller 14 form differential motion of a friction drafting type roller set respectively.
In this embodiment, the third driving roller 21 and the third driven roller 22 are both plum-blossom-shaped roller shafts with notches on the surfaces, and the notches of the third driving roller 21 and the third driven roller 22 are opposite when the third driving roller and the third driven roller rotate in opposite directions to pass through the gap 23.

It should be noted that since the cap can be much stiffer to the body, extruding the cap and body to the same thickness can be problematic for the extrusion feed roller assembly: if the bottle cap is to be flattened, the distance between the third through gaps 23 can only be increased, and the distance between the third through gaps 23 is too large, the flattening effect on the bottle body is not ideal, the subsequent slitting effect on the bottle body is influenced, if the flattening effect of the bottle body is to be ensured, the distance between the third through gaps 23 needs to be controlled within a smaller range, and the bottle cap is hard and can be clamped between the rollers due to smaller passing gaps, so that the rollers lose conveying capacity, and the equipment is blocked; therefore, the surface notches of the quincunx roller shafts can meet the requirement of passing of the bottle caps, the extrusion effect of the bottle body can be guaranteed by the distance between the roller surfaces outside the surface notches, the clamping failure is not easy to occur, and the flattening effect is excellent. Like this, the waste plastic bottle of vertical arrangement falls into the shrinkage pool of feed roller with bottleneck downwards or bottle end downward mode, and the cambered surface length between two adjacent notches equals approximately to the length of plastic bottle, if the bottleneck is downward, then the feed is carried out with the pulling mode to the roller set, if the bottleneck is upwards, then the feed is carried out with friction and promotion mode to the roller set.
