Description

Light-duty short distance Belt Conveying equipment

Technical field

This programme is related to a kind of conveying equipment more particularly to a kind of light-duty short distance Belt Conveying equipment.

Background technology

Belt Conveying equipment can according to material by belt move apart from length and the size of transportable weight of material into Row classification.The tensioning increment of belt is after drive roll and driven roller set upper belt, and belt is tightened up when mechanism tenses actively Roller is compared with the spacing of driven roller by the incrementss of drive roll when installation personnel manual tension to driven roller spacing.

Known, belt is longer, and belt dead weight and weight of material will make belt generate very large deformation, to keep belt flat as possible It is smooth, large-sized tensioning increment is needed, large-sized tensioning increment is generally by the special belt tensioning drum except two rollers To realize；Belt is longer, and to ensure that belt is non-slip, tensioning increment is bigger.

This programme is related to the Belt Conveying equipment that a kind of mobile material distance is shorter, conveying weight of material is lighter, that is, a kind of Light-duty short distance Belt Conveying equipment.The belt of conveying equipment is shorter, when installation, it is only necessary to which smaller tensioning increment can be opened Tight belt keeps its non-slip, when operation, upper layer belt it is sagging less, lower layer's belt will not be encountered.It is conveyed on conveying equipment Material is lighter, when operation, upper layer belt it is sagging less, lower layer's belt will not be encountered, need only the tensile force of very little ensure that Less sagging of belt, tensile force can also be smaller, while the expendable set deformation volume subsequently generated by tensile force It is smaller, i.e., subsequently need the tensioning increment adjusted again also smaller.

The upper layer belt of light-duty short distance Belt Conveying equipment is all approximately plane in unloaded and load operating, mostly defeated Lump material is sent, bulk cargo is also can transport, is suitable for the production such as food, medicine, chemical product, electronics, military project precision machinery and packaging Link.Lump material can be original naked material, can be the package of bulk cargo or lump material.Package can be hard material Material, can also be elastic soft material.

The structure of light-duty short distance Belt Conveying equipment is mostly by motorless drive roll, driven roller, around two The belt of roller limits roller frame, the company of two roller relative distances and position by restricting two fixing ends of each roller The rack of roller frame is connect, the driving motor of driving drive roll in roller frame or rack is fixed on, is fixed in drive motor shaft Belt wheel, connection belt wheel and drive roll drive belt composition.

Roller can be divided into two kinds by its fixing end：One, the fixed roller of axis, that is, roller by axis, be sleeved on axis and connect The bearing of nearly axis end positions, the cylinder rolling drum surface composition being sleeved on bearing, axis, which is stretched out from bearing to both ends, to be gone, and is used for It is fixed；Axis and bearing inner race are fixed, roller and bearing outer ring rotation, that is, the fixing end of this roller is axis；For needing outside The fixed roller of axis of driving mechanism driving, roller rotating part have annular groove or ring with drive belt or drive chain cooperation Tooth, at this moment, the side towards machine frame inside of drive belt or groove or teeth all at rack upper fixing end mounting groove.Two, The fixed roller of bearing outer ring, that is, roller is fixed as one with axis, and axis passes through bearing, and rolling drum surface, axis and bearing inner race revolve together Turn, bearing outer ring and fixed bearing block are fixed, that is, the fixing end of this roller is bearing outer ring or bearing block；Outside bearing Circle or bearing block be fixing end roller be required for greatly external drive motor structure drive, roller rotating part have with drive belt or The groove or teeth of drive chain cooperation, at this moment, drive belt or annular groove or ring tooth roller fixing end can both pacify in rack The side towards machine frame inside at tankage, can also be in the side towards Shelf External at roller fixing end mounting groove.

No-power drum refers to not having rotational power source in itself, by the roller of external world's driving.Driven roller is unpowered rolling Cylinder, is passively driven by belt.The end surface of motorless drive roll has groove or teeth, generally by driving motor, drive Dynamic belt, band wheel drive, or driven by driving motor, shaft coupling and retarder.

Technology at present, first, being directly parallel to the outside of belt direction of travel what two rollers first put roller frame both ends into In the sulculus of opening, then belt was integrally covered roller frame and two rollers, then belt operation side is parallel to by strainer To outside tightening belt, in last integral installation to rack；Second is that two rollers are first covered upper belt, it is inserted into and is located at belt on one side A roller frame mounting hole in, then another movable roller frame passes through the roller fixing end of lace another side Strainer is tensioned and micro-regulating leather belt, is finally installed into rack.It is specific as follows：

The roller frame of most of light-duty short distance Belt Conveying equipment all passes through belt, that is, when installation, belt needs It is first parallel to the major part that roller central axis direction passes completely through the major part and two rollers of roller frame from the side of roller frame, so Back roll frame is connected by right, left side and rack again, and roller frame is driven equipped with being adjusted on being parallel to belt direction of travel The mechanism of tightening belt is come in the position of roller；Mostly use the fixed roller of axis greatly, that is, the fixing end of roller is axis.Roller frame Both ends are designed with the outwardly open small bar-shaped trough for being parallel to belt direction of travel, and the small bar-shaped trough of driven roller one end is for opening Tight belt prevents belt slippage and belt deviation；When installation, first the fixing end of two rollers is put into the small item at roller frame both ends In shape slot, then belt entangled two rollers and roller frame, so the sequencing being packed into drive roll and driven roller does not have It requires, the relative position of the slot bottom of the small bar-shaped trough in a left side right to roller frame does not also require, but requires small bar-shaped trough long enough, protects The fixing end of driven roller is also in small bar-shaped trough when demonstrate,proving tightening belt, that is, due to needing belt tension space so that roller frame Along belt direction of travel longer dimension.Since the small bar-shaped trough on roller frame will at least grow the rolling of mechanism tensioning in place that is tensioned Cylinder fixing end, that is to say, that the axle center for the roller in place that is tensioned is must be over, so, when dismantling belt, although roller can Sufficient space is conceded with movement inwards, mechanism tensioning, retraction raw footage, the perimeter under no-station pole canopy are more but belt is not tensioned The surplus for going out roller frame profile perimeter is still very little, so, it need to manually pull and increase its perimeter to remove roller frame profile；Instead It need to manually pull when installing belt and increase strap circumference to be inserted in roller frame profile.Due to belt inner surface and roller table Face contacts and moves synchronously, and needs frictional force, therefore very puckery, so, belt is very tight, gruelling when belt being allowed to pass through roller frame. If easily through belt, it is tensioned space and just may not be enough to, belt will skids.So roller frame and rack are not only tied Structure is complicated, of high cost, installation with dismantle it is also extremely difficult, machinery hinder and manually pull all be easy to allow belt local deformation or Whole damage.

The tensioning of drive belt is the position by the opposite drive roll of pan drive motor adjustment driving motor in rack It sets to realize.The tensioning needs of drive belt control, and drive belt can fluff after long-play, and drive belt is too tight Driving motor power can be wasted and reduce the drive belt service life；It is too loose drive belt to be caused to skid, driving drum and driving electricity Machine cannot synchronize, and can not control belt speed by controlling driving motor.This structure driving motor can be only installed in rack.

The difficulties such as the laborious, damage not being avoided that when allowing belt to pass through roller frame for solution, the light-duty short distance belt having Conveying equipment roller frame be split as it is right it is left separation, it is two movable, mutual distance is adjustable, one pass through two rollers one side Fixing end, another pass through two rollers another side fixing end, each roller frame, which has, is being parallel to belt operation side Carry out the strainer of tightening belt to the position by adjusting driven roller, left and right roller frame is finally separately fixed at a left side for rack Right both sides, driving motor are fixed on the roller frame of certain side or in rack；The big roller for mostly using axis rotation, that is, roller Fixing end is bearing outer ring or bearing block.Bearing block or bearing can also be on rollers on the roller frame of left and right.This knot Structure is since the mutually matched required precision such as bylinder of rolling left of axis, bearing outer ring or bearing block and the right side is high, and roll left bylinder on the right side when installation It must relatively move again, bad accurate fixed relative position, finally, the right, bylinder that rolls left must also be according to the axial limiting position of roller It sets and keeps relative distance in rigid rack to be fixed at random and absolutely fix.Left and right roller frame relative position is fixed not It is good, belt operation will be influenced, it is big that belt is easy sideslip, noise.Also it must be driven by integral translation to be tensioned the position of driving motor Dynamic belt.This structure, set belt are easy, but are manufactured and installation is very troublesome, one people's bad operation when installation, of high cost, Also highly difficult when dismounting, people's operation is likely to that roller is made to slide ground.

An articulated shaft is arranged in also scheme in the middle part of roller frame, and articulated shaft is parallel with roller, first passes through an articulated shaft both sides Divide roller frame formed an obtuse angle, after on belt sleeve, then the roller frame at articulated shaft both ends is allowed to be unfolded and fix, in 180 ° Plane, with this tightening belt, then the roller frame after grip upper belt is installed in rack；Program manufacture complexity, cost It is high.

Belt is looped around on two rollers, is known as upper layer belt in the part belt of two drum overheads operation, at two The part belt of roller lower part operation is known as lower layer's belt.Since even belt both sides are equipped with striker plate, but striker plate and skin The distance that band must still reserve belt deviation is come, so, often there is impurity to enter upper layer belt and lower layer's belt in belt operational process And the inner space that both sides roller frame is surrounded, these impurity effects sanitary condition of belt, also can be clipped in repeatedly belt with Among roller, belt running stability is influenced, wears belt and cylinder surface.Since the roller frame of the prior art is blocked in belt Both sides, the inner space surrounded to upper layer belt, lower layer's belt and roller frame carries out daily cleaning and cleaning is highly difficult, to food The high user of the hygienic requirements such as product, medicine increases many use costs, also affects runnability and the service life of belt.

As it can be seen that the shortcomings that current technical light-duty short distance Belt Conveying equipment, is as follows：Roller frame and rack are separation Structure, complicated integral structure, installation, adjustment and dismounting are difficult, and manufacture is difficult, of high cost；Not easy cleaning and cleaning, it is unhygienic, Service life is low.

It is heavy that recessed structure can integrally be made with rack, bending forms.

The advantageous effect of this programme：

One, the installation and removal of belt are very easy to：

The right of this programme is using the light-duty end of L-shaped tin roller mounting groove apart from Belt Conveying structure, either drive roll Or driven roller, any one is installed to right tin roller mounting groove, and the installation of belt and roller, dismounting can all be made to become to hold very much Easily.

If driven roller is mounted on right tin roller mounting groove, using in for unclamping the upper right end of front vertical plate and back vertical plate Tight mechanism removes tensile force, and strap circumference retraction becomes smaller, to drive the driven roller of rack right end from rack right end to machine Mobile feature in the middle part of frame, from the right end on the top of front vertical plate and back vertical plate by the position of proximal edge accordingly to central rack Direction is slotted and upward opening, recycles hollow trough body structure to ensure that belt can be moved unhinderedly, can make driven rolling easily Cylinder and the belt on the right take out from rack right end top together.Then, if 1, drive roll uses the electronic rolling of electric motor built-in Cylinder, since it does not have the restriction of drive belt, can directly take out together with the belt on the left side；If 2, left tin roller mounting groove Slot bottom need only unclamp the attachment screw of driving motor and front vertical plate, driving electricity slightly backwards to the strainer of not drive belt Around the circular hole center of circle, tin roller mounting groove direction rotates some machine to the left, you can takes drive from the belt wheel that driving motor axis axis is stretched Dynamic belt, together takes out drive roll and the belt on the left side；If 3, left tin roller mounting groove slot bottom is backwards to equipped with drive belt Strainer, strainer need only be unclamped slightly, you can take drive belt from the belt wheel that driving motor axis axis is stretched, Drive roll and the belt on the left side are taken out together.When installing belt, overall process in turn, locks right tin roller mounting groove Strainer can tightening belt, and pass through the two side walls of belt, strainer and groove body fix driven roller.

If drive roll is mounted on right tin roller mounting groove, using in for unclamping the upper right end of front vertical plate and back vertical plate Tight mechanism removes tensile force, and strap circumference retraction becomes smaller, to drive the drive roll of rack right end from rack right end to machine Mobile feature in the middle part of frame, from the right end on the top of front vertical plate and back vertical plate by the position of proximal edge accordingly to central rack Direction is slotted and upward opening, and hollow trough body structure is recycled to ensure that belt can be moved unhinderedly, can make actively to roll easily Cylinder and the belt on the right take out from rack left upper part together.Then, no matter drive roll uses electric motor built-in motorized pulleys, Or when drive roll is driven using driving mechanism and left tin roller mounting groove slot bottom has strainer backwards, positioned at cylinder installation of rolling left Driven roller in slot can the freely notch movement of tin roller mounting groove to the left, taken out together with the belt of left end.Installation When belt, in turn, only left tin roller mounting groove slot bottom has strainer to overall process backwards, needs to answer strainer Position is retracted can first be tensioned drive belt so as to the strainer of rack right end；Lock the strainer of right tin roller mounting groove Tightening belt, and fix drive roll by the two side walls of belt, strainer and groove body.

This programme no longer needs to dismantle any roller frame or rack, can easily pass remove and be put into from rack roller and Belt uses L-shaped mounting groove to realize the dismounting of belt because of rack right end, then dismantles belt and will not interfere on production line Other equipment on the right of this equipment.

If α=90 °, handling belt will not interfere with the other equipment of this equipment all around on production line.

If α=0 °, the upper and lower cell wall in horizontally disposed straight U slot structures of left tin roller mounting groove can be rolled with effective restraint The up-down vibration of cylinder fixing end reduces the shake up and down in belt operational process, larger suitable for being vibrated because of unbalance mass, Roller；When left tin roller mounting groove has strainer behind, the adjustment of the strainer does not influence the levelness of belt surface.

0 ° of 90 ° of ﹤ α ﹤ can reduce other equipment when dismounting belt and roller to this equipment on production line all around Interference, and adapt to more vibrate larger roller because of unbalance mass,；There is strainer behind in left tin roller mounting groove When, tensioning adjustment influences the levelness of belt smaller.

Belt both need not difficulty be passed through hard roller by roller frame compared with prior art and body, this programme Frame also difficulty need not first install movable roller frame on two sides, it is fixed on the rack again, more need not be rolling Bylinder expansion, bending, fixation, enormously simplify installation and removal, will not injure belt because of handling.

Two, belt is stable, be not easy sideslip, noise is small：

The integration cutting of rack, groove profile bending structure make the position each other of mounting groove become fixed consistent, and roller is fixed After holding on the mounting groove for the fixed band opening in position each other for snapping into hollow groove body top or so end, before two roller fixing ends The positioning precision on a rear right left side is much higher compared with prior art.

Three, overall structure is simpler, manufacture is easier, cost is lower：

Bending knot is also used using the fixed support ear of integration cutting, groove profile bending structure, especially belt tensioning mechanism When structure, rolling left bylinder and rack across the roller frame of belt and the relatively-movable right side compared with prior art, simple in structure, system It makes easy, at low cost.

Four, belt easy cleaning and cleaning, much cleaner, performance is more stable, longer life expectancy, use scope is wider

Because the structure of this programme does not have a roller frame on belt both sides, upper layer belt and lower layer's belt enclosed space it is unobstructed, Open, good operation, it is easy to carry out daily cleaning and cleaning, compared with prior art, be more broadly applicable to various food, defend The industries such as life, pharmacy, electronics, chemical product.

Five, drive belt tensioning adjustment is easier：

The pan drive motor of this programme compared with prior art is tensioned the structure of drive belt, need only belt tensioning drum installation The strainer of trough rim, easy to operate, a people can.And the translation mode of the prior art, neither one mounting hole can To rely on, a people is completed at the same time tensioning and fixed operations difficult.

Six, protection belt and cylinder surface are easy：

Distributing damper is fixedly installed between front vertical plate and back vertical plate, distributing damper is in herringbone, and distributing damper is horizontal It is arranged between upper layer belt and lower layer's belt and close to the upper surface of lower layer's belt, can be easy in a belt operational process Impurity between on into upper layer belt and lower layer's belt is extruded.And the prior art is not easy that distributing damper is arranged, once have Impurity enters the centre of belt and roller frame, it repeated multiple times may be clipped between belt and the surface of roller, damages skin Band and cylinder surface.

Seven, structure is more simplified, professional integrated level higher, more reliable performance：

Drive roll such as uses the dynamic roller of electric motor built-in motorized pulleys that can save tensioning compared with prior art Drive belt and belt wheel and its installation and debugging and Breakdown Maintenance, especially drive belt fatigue fracture.

Eight, the size of roller fixing end is more adaptable：It, can by adjusting the relative position of 7 font workpiece and front vertical plate With the left vertical slot for being combined into various sizes and right translot, it is suitable for different-diameter or the roller of end size.
