In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

As shown in fig. 1 to 3, the present invention provides a quick change unpowered roller way, comprising: a roller 1 and a bracket body 2, wherein the roller 1 is used for conveying articles placed on the roller; the support body 2 is used for supporting and fixing the roller 1. With respect to the above components, detailed description is given below.

Roller drum

The roller 1 is used for enabling an article placed on the roller 1 to flow and transmit through rolling of a plurality of rollers 1. Roller 1 includes roller 11 and cover and establishes a plurality of cylinders 12 on the roller 11, wherein every two constant head tank (111) have been seted up to the both ends mirror image of roller (11) to and a plurality of cylinders 12 end to end are "one" word and arrange, and is a plurality of a cushion 13 has respectively been decided to the cover in the end to end department of cylinder 12, cushion 13 one end and cylinder 12 contact, the other end and vertical portion 21 contact, the effect that cushion 13 played is filled cylinder 12 with clearance between the vertical portion 21, it is a plurality of to play from both sides location the effect of cylinder 12.

In order to increase the operational stability of the roller 1, the rollers 12 are three and the rollers 12 on both sides are arranged symmetrically with respect to the roller 12 in the middle. Each independent roller 12 can roll independently under the effect of external force, and the rollers 12 in the same row can roll in sequence to transfer objects, so that the passing speed of the objects can be adjusted by the rollers 12, when a small and high-speed object passes through, the rollers 12 roll to absorb part of kinetic energy and transfer the object to the next roller 12 in the same row, the effect of dispersing the kinetic energy of the object is achieved, and the speed of the object can be reduced by the linkage of the rollers 12.

Support body

The support body 2 comprises two rows of vertical parts 21 and a plurality of U-shaped grooves 22 which are arranged in a mirror image mode, the vertical parts 21 are arranged at two ends of the roller 1 and used for axially positioning parts in the roller 1, and the plurality of rollers 1 are rotatably supported on the support body 2. Each of the vertical portions 21 is provided with a plurality of U-shaped grooves 22 along the length direction thereof. Both ends of the roller 1 are rotatably supported on one of the U-shaped grooves 22. Through the 2 cooperation rollers 1 of stake body, can realize bearing to single roller 1, through the setting of vertical portion 11 in the stake body, can realize bearing to the roller of a plurality of the same specifications, and set up U-shaped groove 22 in vertical portion, can realize and the roller 1 between the cooperation to play and carry out spacing effect to it, the groove of U-shaped groove 22 provides a good condition for the rotation of roller simultaneously.

The following describes the composition structure of the vertical portion 21 in detail, where the vertical portion 21 includes a vertical bracket 211 having an L-shaped cross section, the vertical bracket 211 includes a horizontal plate 2112 and a vertical plate 2111 which are perpendicular to each other, and the U-shaped grooves 22 are formed on the edge of the vertical plate 2111 in the length direction.

In order to further ensure the connection stability of the roller 1 and the bracket body 2, two fixing blocks 213 are arranged on the outer wall of the side surface of each U-shaped groove 22, the fixing blocks 213 are square, and a ring is arranged in the middle of each fixing block. Two positioning holes 111 are formed in the side walls of two end faces of each roller shaft 11, the positioning holes 111 penetrate through the side walls of the roller shafts 11, the size of each positioning hole 111 is the same as that of each circular ring, and threads in the same rotating direction are formed in the positioning holes 111 and the inner walls of the circular rings. After the roller shaft 11 is placed in the U-shaped groove 22, the roller shaft 11 is rotated to make the positioning hole 111 and the ring in the fixing block 213 keep the same horizontal height, and then bolts are inserted into the positioning hole 111 through the fixing block 213 from both sides by means of threads. The effect of this solution is to limit the axial movement and rotation of the roller shaft 11 in the U-shaped groove 22 by means of bolts. If roller 1 is when transporting article, roller 12 rolls and drives roller 11 rotates, can make roller 11 with U-shaped groove 22 produces friction and sound production abnormal sound, and this friction can be to roller 1 with prop up the frame body 2 coupling part and cause the damage to influence the stability of connecting. And meanwhile, the roll shaft 11 is prevented from sliding out of the roller way under the action of axial external force.

In order to prevent the vertical plate 2111 from being bent by the axial thrust generated by the roller 1, the joint of the horizontal plate 2112 and the vertical plate 2111 is rounded, the purpose of rounding the joint of the horizontal plate 2112 and the vertical plate 2111 is to enhance the bending stability of the joint, and the rounding plays a role similar to a support beam and can play a certain supporting role for the vertical plate 2111. The larger the diameter of the pilot circle is, the better the supporting effect is. However, too large a diameter will also result in waste of material, and during manufacturing, the diameter of the pilot circle should be determined according to the magnitude of the axial force specifically received by the vertical plate 2111. The free ends of the horizontal plates 2112 and the vertical plates 2111 are rounded.

In order to ensure the contact stability of the vertical portion 21 and the ground, the vertical portion 21 further includes a plurality of support legs 212, and the plurality of support legs 212 are respectively carried on the horizontal plate 2111. The supporting legs 212 can bear and fix the vertical part 21, further bear the roller 1, and further bear the whole roller bed, so the supporting legs 212 need to have enough strength to support the installation and working stability of each part.

In order to stably connect the supporting leg 212 with the horizontal plate 2111, the bottom of the supporting leg 212 is through, the supporting leg 212 is provided with a bearing plate 2121, and the area of the end surface of the bearing plate 2121 is larger than that of the supporting leg 212, which is intended to completely cover the bearing plate 2121 on the side wall of the supporting leg 212, so that the connecting stability between the supporting leg 212 and the bearing plate 2121 is stronger. The bearing plate 2121 and the horizontal plate 2111 are fixedly connected through bolts.

In the work, a plurality of rollers 1 pass through the U-shaped groove 22 cooperation on stake body 2, and the both ends face of roller 11 can pass through bolt and U-shaped groove 22 lateral wall fixed connection, and after the installation of roller 11 was accomplished, roller 12 can overlap and establish and roll on roller 11, and roller 11 can not rotate. The vertical portions 21 clamp the roll 1 from both sides of the roll 1 and fix its axial position. Thereby realizing the flowing of the objects under the rolling action of the rollers 1.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
