Description

Spring conveying roller, combined conveying roller, groove roller and conveying assembly

Technical Field

The invention relates to the field of mechanical conveying rollers, in particular to a spring conveying roller, a combined conveying roller, a groove roller and a conveying assembly formed by the spring conveying roller and the combined conveying roller.

Background

The roller is a cylindrical part, is divided into a driving roller and a driven roller, and is widely applied to various transmission and conveying systems such as a circular screen printer, a digital printer, mine conveying equipment, papermaking and packaging machinery and the like. The rubber roller is one of the rubber rollers, which is a roller-shaped product prepared by taking metal or other materials as a core and coating rubber outside the rubber roller through vulcanization.

In the field of conveying of packaging machines such as woven bags and plastic bags and machines such as paper cutters and the like with material conveying stations, because the conveyed materials are thin in thickness (such as printing paper with the thickness of less than 1mm, packaging bags, woven bag inner films, woven bag bodies and the like) and high in flexibility, in the conveying process, because the conveying assembly is usually conveyed by two conveying rollers which are in clearance fit and oppositely arranged, the materials between the front conveying position and the rear conveying position often sag; especially, on the outlet side of the material, the material is also easy to be attached to the outer circle of the roller and falls, which is not convenient for further processing of the subsequent procedure and is also not convenient for collecting the material.

Based on the above, the application of the scheme is provided.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a spring conveying roller and a spring conveying roller assembly, which can improve the clamping condition of two conveying rollers which are in relative clearance fit to thin and soft materials so as to ensure the tensioning state of the materials during conveying and be more convenient for conveying and connection with a subsequent processing station.

In order to achieve the purpose, the invention provides a spring conveying roller which comprises a columnar roller body and transmission shafts arranged on two end faces of the roller body.

Above-mentioned bulge structure forms the fold when making the material by two conveying roller centre gripping, and the folding broken line that forms of fold department can strengthen the rigidity power of material to make it be difficult to flagging, also more be favorable to the tensioning of material. The folds are easy to expand outwards, and the rigidity of other parts of the material except the connecting points is enhanced, so that the integral rigidity of the material is improved.

In addition, in the structure, the spring strip protrudes out of the surface of the roller body, so that the material can be pressed to one side of the surface of the other conveying roller in clearance fit with the spring conveying roller, the material can be clamped between the two conveying rollers through the protruding structure, and the material can be in a tensioning state when being positioned between the front conveying station and the rear conveying station, so that the material can be conveyed and processed conveniently.

Besides the function of the convex structure, the invention adopts the spring strip, and can also improve the transportation efficiency of materials or enhance the rigidity force of conveying materials from the following aspects: the spring strip is a strip spring and is formed by coiling a plurality of coil bodies, when the spring strip is used, the axis of the spring strip is superposed with a groove path, in the spring strip, the contact point of a material and the coil bodies of the spring strip is point contact or line contact with a short length (less than 5 mm), when the point contact and the line contact with the short length are in contact with the material, the pressure intensity of the material on the contact point is far greater than that of the material in direct contact with the surface of a roller body, and the clamping force can be effectively improved.

Secondly, the spring strip is in multi-point contact with the material: firstly, unless the thickness of the spring strip is very large, the spring strip and the material are in contact with each other by at least 2 adjacent ring bodies, and the 2 adjacent ring bodies can cooperate to grab the material; secondly, the spring strips are elastic, wherein any coil body is connected with the adjacent coil body in an end mode, and the middle part of the coil body can swing, so that when the coil body of the spring strip is in contact with the material, the coil body of the spring strip can incline towards the conveying direction due to friction force between the coil body of the spring strip and the material, the part of the coil body of the spring strip can be separated from the material later, the contact time between the material and the part of the coil body of the spring strip is longer, and the number of the coil bodies of the spring strip in contact with the material is larger.

Compared with single-point contact, the multi-point contact can form more fold lines and folds with wider radiation range, so that the integral rigidity of the material is improved. Compared with single-point contact, the multi-point contact has more contact points and more clamping points with materials, and can help to improve the clamping force.

And thirdly, when the coil body of the spring strip inclines towards the conveying direction, the coil body of the spring strip has resilience force, and the resilience force can apply an opposite acting force to the applied materials, so that tension is provided for the tensioned state of the spring strip. That is, the resilience of the coil of the spring strip further increases the stiffness of the material.

And the coil body of the inclined spring strip can make the formed folds have longer duration due to the delayed separation characteristic, thereby being beneficial to the stability of material conveying.

And fifthly, under the combination of the second point and the third point, the multipoint contact is equivalent to multi-grabbing, compared with the single-point contact, the flexible material cooperation enables the spring strip with superior grabbing force to effectively grab the material in a multipoint and fold shape, and the formed fold state is more stable. And the multi-point grasping mode is more beneficial to the stability of material conveying during conveying.

Sixth, because the roll body is the pivoted, and the circle body of spring bar is the vertically for the direction of delivery of material, consequently under the roll body is rolling state, the circle body of spring bar also is equivalent to the plectrum, promotes the material to direction of delivery for whole transportation process is more nimble, efficiency is higher.

It should be noted that, because the spring strip is used in the invention, the radian of the fold formed on the material is small, and the force when the fold is gripped is also smaller than the force when a person grips the fold formed on the material, the situation that the fold of the material is difficult to recover due to the pleating of the spring strip when the material is conveyed does not occur basically. According to the invention, through the folds formed on the material, on one hand, the structural strength and the rigidity force of the material are enhanced by utilizing the local uneven concave-convex surface of the material after the folds are formed, on the other hand, the stress acted on the material from the outside is transmitted to all parts of the material through the structural characteristics of the material by utilizing the mutual acting force between the spring strip and the material, so that the rigidity force of the material is enhanced.

The invention further provides the following: the groove is a spiral groove or an annular groove, the spiral groove and the annular groove are distributed around the roller body, the groove and the spring strip which is located in the groove and protrudes out of the outer surface of the roller body can be guaranteed to be arranged on each side surface of the roller body, and therefore when the roller body rotates to work, the spring strip can exert the function of the spring strip to improve the rigidity of materials and the clamping force of the roller body.

In order to make the material conveying process stable and everywhere balanced, the invention is further provided with the following components: the spring strip is the equidistance spring, so, when the material was through the roll body, its power that receives was unanimous, the material can not appear because of the atress circumstances such as the skew takes place to carry that the inequality takes place.

The invention further provides the following: the spiral groove or the annular are two at least, and it can form two at least action points with the material between, and the more the action point, the better effect and the availability factor of spring strip are theoretically.

In order to improve the overall stability of material conveying, the invention is further provided with the following components: at least two of the ring grooves or the spiral grooves have the same structure and are distributed in parallel. Under parallel distribution, when the material passes through the spring conveying roller, the position of each action point is the same, and the material is easy to stabilize; in addition, even distribution is easy to realize under parallel distribution, so that the stress of each part of the material is balanced.

In order to facilitate the processing and adapt to the actual use requirement, the invention is further provided with the following components: the ring groove is arranged in parallel with the radial plane of the roller body or inclined to the radial plane of the roller body.

The invention is further arranged as follows for convenient use: in the ring groove, two ends of the spring strip are fixed by welding or sleeving.

The invention further provides the following: the spring conveying roller can enhance the rigidity of materials through the spring strip in the rubber roller conveying process, so that the spring conveying roller is more suitable for the rubber roller conveying process, and has a more excellent use effect.

In order to ensure the strength and rigidity of the spring strip, the invention further comprises the following steps: the spring is made of steel alloy or steel material, and the service life is longer.

The groove roller 200 is provided with a second groove 211 on the outer surface thereof corresponding to the position of the first groove 111 in the spring conveying roller 100.

Embodiment 1 referring to fig. 1, a structure of a spring feed roller 100 includes a cylindrical roller body 110 and a transmission shaft provided on both end surfaces of the roller body 110, the roller body 110 is provided with a plurality of first grooves 111 on an outer surface thereof, the first grooves 111 are annular grooves, are provided around the roller body 110 in parallel with a radial plane of the roller body 110, spring strips 300 are provided in the first grooves 111 in a path overlapping with the first grooves 111, fig. 1 is limited to a drawing level, the spring bar 300 is indicated by a hollow tube, which is best understood herein in connection with the spring bar 300 of fig. 2-4, and, in addition, is limited to the level of the drawing and for purposes of clarity, the spring strips 300 in fig. 2-4 are simplified-shown in single line form-in practice the spring strips presented in the figures are of a certain thickness, in the case of a wire pitch of less than 1mm, the spring bar 300 will be close to the tubular object shown in fig. 1 and 5.

The spring bars 300 are fixed in a welding mode after being connected end to end, and the spring bars 300 are prevented from falling off in the using process. As can be seen from fig. 4, the surface of the spring bar 300 protrudes from the surface of the roller body 110, in this embodiment, in order to make the whole stable and balanced, the spring bar 300 preferably adopts equidistant springs with inconvenient diameters, wherein the elastic force of the spring bar 300 is preferably 20N-50N, and the wire distance is preferably less than 5 mm. In addition, the spring bar 300 may be made of steel alloy or steel material for welding and fixing, and its service life can be prolonged. In one embodiment of the present invention, the spring strip 300 has a diameter of 2-14 mm, a length of 6-50 cm, and a linear distance of 1-3 mm (or stated as, two adjacent rings are tightly attached and are in clearance fit with each other).

Moreover, in this embodiment, the number of the spring strips 300 preferably corresponds to the number of the ring grooves, and may be more or less, and at least two spring strips should be included and preferably uniformly distributed on two sides of the roller body 110, so as to achieve an optimal action effect, and at most 12 to 13 spring strips or more as shown in fig. 2 may be included, and it is only necessary to pay attention to the design of the distance according to the actual situation, and the overlapping range of the radiation areas of two adjacent folds 410 formed when the spring strips 300 act on the material 400 is as small as 1/2 of the width of the radiation area in the transverse direction (i.e. the axial direction of the conveying roller), so as to ensure the radiation area of the folds 410 and save the material usage at the same time of.

Except for the above welding and fixing manner, the diameter of one end of the spring bar 300 can be slightly smaller than the other end so as to wrap the other end, and when the spring bar 300 is used, the connection can be completed only by rotating one end of the spring bar 300 in advance or reversely rotating the two ends of the spring bar 300 in advance and then sleeving the head and the tail of the spring bar 300. The fixing mode is realized by utilizing the elasticity of the spring strip 300 and the clearance between the ring bodies, other connecting pieces or other means are not needed, but the connection can be broken when the conveying roller runs at high speed, but the normal operation of the equipment cannot be influenced when the number of the ring grooves is large, and the core spring strip 300 is installed again for use only after the machine is stopped.

Alternatively, glue or the like may be used to secure the ends of the spring strip 300.

Example 2 this example differs from example 1 in that: the ring grooves are or are inclined to the radial plane of the roller body 110, i.e. in this embodiment, the first grooves 111 are inclined grooves, and correspondingly, the first grooves 111 in embodiment 1 are straight grooves.

Embodiment 3 this embodiment differs from the above embodiments in that: the first grooves 111 are spiral grooves, and are protruding out of the spring strip 300, and the number of the spiral grooves is preferably more than two and the spiral grooves are distributed in parallel. However, in order to keep the force applied to the material 400 passing each time to be the same when the material 400 is conveyed by the roller 110 in a parallel distribution, the number of the spiral grooves used in the staggered distribution and the proper distance need to be controlled according to actual conditions, so that the spiral grooves are uniformly distributed as much as possible.

Embodiment 4 this embodiment differs from the above embodiments in that: in the present embodiment, the first groove 111 is provided as an intermittent ring groove, which includes two parts of an interruption and a slot, and the spring strip 300 is only provided in the slot. In one embodiment of the continuous material 400 transportation process, the length of the discontinuous portion of the discontinuous ring groove is preferably smaller than the length of the groove, which requires at least two adjacent first grooves 111 to be staggered, so that the spring bar 300 can always act during the material 400 transportation process, and the best action effect can be achieved. Therefore, in actual use, two adjacent and staggered first grooves 111 need to be matched for use, and if two stable action points need to be provided, two first grooves 111 need to be matched in pairs for a total of four first grooves 111.

In one embodiment of the intermittent feeding process of the material 400, the length ratio of the discontinuous portion and the grooved portion of the discontinuous ring groove is designed according to the interval time of the intermittent feeding. In this case, it is not required that two adjacent discontinuous ring grooves are staggered and complementary, and it is only required that the length of the discontinuous part is not more than the time between the discontinuous parts when the discontinuous part is actually rotated in work.

In this example, the spring bar 300 is difficult to form a loop, and both ends of the spring bar 300 can be fixed to both ends of the groove only by using an adhesive such as glue.

In the above embodiments 1 to 4, the thickness of the spring bar 300 is preferably 3 to 14mm, and the length thereof can be adjusted according to practical use, and one range of the spring bar used more often is 6 to 30 cm.

Embodiment 5 referring to fig. 1, this embodiment provides a grooved roller 200, which includes a cylindrical roller body 210 and transmission shafts disposed on both end surfaces of the roller body 210, and a second groove 211 is opened on the surface of the roller body 210, and the position of the second groove 211 corresponds to the position of the first groove 111 in the spring conveying roller 100 provided in the above embodiment.

Embodiment 6 as shown in fig. 10, this embodiment provides a combined conveying roller, which includes the spring conveying roller 100 and a brace 500 parallel and adjacent to the spring conveying roller 100, where the groove is a circular groove, the spring strip 300 is in an annular shape in an end-to-end connection, and the annular spring strip 300 is sleeved on the roller body 110 and the brace 500 together. Through the cooperation of the stay bar 500, the distance between two adjacent rings in the spring bar 300 can be adjusted by adjusting the distance between the stay bar 500 and the roller body 110, so as to adapt to different use requirements, and the spring can be prevented from being hung on the ring groove in a loose manner, so that the spring is convenient to mount and is in a tight state, and the action effect is improved.

Embodiment 7 this embodiment provides a conveying assembly comprising any one of the spring conveying rollers 100 provided in the above embodiments or a combination conveying roller and the grooved roller 200 provided in embodiment 5. As shown in fig. 1 to 5, the spring conveying roller 100 is disposed opposite to the groove roller 200, and the first groove 111 on the outer surface of the spring conveying roller 100 is located corresponding to the second groove 211 on the outer surface of the groove roller 200, so that the spring bar 300 located in the first groove 111 is inserted into the second groove 211 protruding from the outer surface of the spring conveying roller 100. With reference to fig. 3 and 5, it can be seen that there is a concave-convex fit relationship between the spring strip 300 and the second groove 211, on one hand, it enables the material 400 to form a fold 410 when being clamped by two conveying rollers, and the fold line formed by folding the fold 410 can enhance the rigidity of the material 400. On the other hand, the spring strip 300 presses the material 400 into the second groove 211 to clamp the material 400 between two conveying rollers, so that the clamping force of the matched spring conveying roller 100 and groove roller 200 on the material 400 is improved.

The action effect is shown in fig. 8, and a plurality of action trace lines 420 are formed on the contact of the material 400, but the action effect is only illustrated as an illustration of one action effect, and the actual action trace line 420 has a certain deviation from the figure.

In the above embodiment, in order to keep the force applied to the material 400 during the conveying process consistent and keep the material 400 stressed or pleated in a more balanced manner in the axial direction of the conveying roller, the structures of the first grooves 111 are kept the same, the spring strips 300 arranged therein are also kept the same, and the spring strips 300 themselves are preferably equidistant springs with the same diameter (except for the head and the tail ends connected, the head and the tail ends and the rest parts can also keep the same diameter and spacing when glue is used for bonding). Therefore, in individual cases, for example, when the thickness of the material 400 is not uniform and the conveying roller is vertically arranged, the groove depth and the size of part of the first grooves 111 can be adaptively adjusted, that is, the groove depth and the size of two adjacent first grooves 111 can be different, and correspondingly, the sizes, the thicknesses and the line distances of the corresponding spring strips 300 can also be different when the groove depths and the sizes of two adjacent first grooves 111 are different; even in special cases, such as intermittent feeding of the material 400, the spring bars 300 on the side of the portion of the roller body 110 directly contacting the material 400 may be arranged at a specific pitch, thickness, the rest may be arranged at another pitch and thickness, or the rest may be replaced by another part (e.g., tube, connecting wire).

In summary, the present invention provides a spring conveying roller 100, a grooved roller 200 used in cooperation with the spring conveying roller 100, and a conveying assembly composed of the spring roller and the grooved roller 200 and used in cooperation with conveying, wherein a first groove 111 and a second groove 211 are disposed on the surfaces of the spring conveying roller 100 and the grooved roller 200, the first groove 111 is provided with a spring bar 300, the spring bar 300 can be embedded into the second groove 211 when the spring bar 300 and the second groove 211 are used in cooperation, and the rigidity of a material 400 and the clamping force of the conveying assembly on the material 400 are improved by using the concave-convex relationship between the spring bar 300 and the second groove 211.
