[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1:

[0049] like Figures 1 to 4 As shown, the present invention provides a roller support assembly, including a guide rail 1, a sliding member 2, a support 3 and a transmission control component 6. The guide rail 1 is a straight profile with a "C"-shaped cross section. Figure 4 As shown in , the upper side of the guide rail 1 extends outward by a certain width compared to the lower side of the guide rail 1, so that the upper side of the guide rail 1 is wider than the lower side of the guide rail 1. A dovetail groove 11 is provided on the lower surface of the lower side of the guide rail 1.

[0050] Recombination Figure 5As shown, the sliding member 2 includes a left slider 21 and a right slider 22 that are symmetrically adapted to the shape of the dovetail slot 11. The left slider 21 is slidably mounted on the left side of the dovetail slot 11, and the right slider 22 is slidably mounted on the right side of the dovetail slot 11. The sliding member 2 adopts a split structure, and the left slider 21 and the right slider 22 can be installed separately, which is convenient for the installation and removal of the sliding member 2. A certain gap is left between the installed left slider 21 and the right slider 22 to facilitate the removal of the left slider 21 and the right slider 22. Connecting ear plates 23 are welded at both ends of the left slider 21 and the right slider 22, and mounting through holes are provided on the connecting ear plates 23.

[0051] The support 3 is clamped between the connecting ear plates 23 on both sides, and corresponding threaded holes are provided at both ends of the support 3, and the support 3 is fixedly connected to the connecting ear plates 23 by fixing bolts 33. The upper side of the support 3 has a raised hexagonal positioning block 31, and corresponding trapezoidal positioning grooves 24 are provided on the opposite sides of the left slider 21 and the right slider 22. When the support 3 is connected with the left slider 21 and the right slider 22, the positioning block 31 is inserted into the positioning groove 24, which plays a role in positioning the relative position of the left slider 21 and the right slider 22, improves the connection strength with the sliding member 2, and enables the sliding member 2 to form a stable sliding fit with the dovetail slide 11.

[0052] The support 3 is provided with a bearing hole, in which a bearing 42 is fixed. The roller 4 is inserted into the bearing 42, and a pulley 41 for transmission is fixed at the end of the roller 4. A transmission belt 5 is arranged above the pulley 41, and the transmission belt 5 is circulated and rotated under the action of the power device.

[0053] Combination Figure 1 , Figure 3 and Figure 4 As shown, the transmission control assembly 6 is fixed on the outside of the support 3 and is used to control the transmission between the pulley 41 and the transmission belt 5 .

[0054] The transmission control assembly 6 includes an L-shaped support plate 62, and the outer side surface of the support 3 has a connecting plate 32 extending upward. The vertical plate in the L-shaped support plate 62 is fixedly connected to the connecting plate 32 by connecting bolts 34, and the support 3 and the L-shaped support plate 62 form a "Z"-shaped structure. The horizontal plate in the L-shaped support plate 62 fits the upper side of the guide rail 1, and the horizontal plate is fixed with a fastening bolt 621 that abuts against the upper side of the guide rail 1. The L-shaped support plate 62 can slide on the guide rail 1 together with the support 3, and then adjust the position, and then the L-shaped support plate 62 and the support 3 can be locked on the guide rail 1 by the fastening bolt 621.

[0055] The guide assembly 63 includes a sliding column 631 and two auxiliary sliding rods 632 which are parallel to each other. The two auxiliary sliding rods 632 are symmetrical along the sliding column 631. The sliding column 631 is arranged vertically, and the axis extension line of the sliding column 631 intersects with the axis of the pulley 41. One end of the sliding column 631 and the two auxiliary sliding rods 632 is fixedly connected to the horizontal plate in the L-shaped support plate 62, and the other end is fixedly connected through the baffle 633.

[0056] The sliding seat 64 includes a pair of symmetrical arc plates 642, and a slide plate 641 is fixed between the two arc plates 642. Three sliding holes are provided on the slide plate 641, and the slide plate 641 is correspondingly slidably connected with the slide column 631 and the auxiliary slide rod 632 through the sliding holes. Two auxiliary pressure wheels 61 are rotatably installed between the two arc plates 642, and the two auxiliary pressure wheels 61 are symmetrical along the slide column 631. The elastic member 65 includes a spring sleeved on the slide column 631, and the two ends of the spring are against between the L-shaped support plate 62 and the slide plate 641. The spring provides a downward thrust to the slide plate 641, so that the auxiliary pressure wheels 61 at both ends of the arc plate 642 press the transmission belt 5 to the pulley 41, so that the transmission belt 5 and the pulley 41 are pressed tightly, and the transmission between the transmission belt 5 and the pulley 41 is realized.

[0057] like Figures 1 to 5 As shown, when in use, first fix the left slider 21 on the support 3 by the fixing bolts 33, and buckle the right slider 22 in the corresponding position on the support 3; lift the support 3 to the position of the dovetail slot 11, so that the left slider 21 is installed on the left side of the dovetail slot 11, and then move the right slider 22 to the right side of the dovetail slot 11, and fix the right slider 22 on the support 3 by the fixing bolts 33; finally, fix the L-shaped support plate 62 in the transmission control assembly 6 to one side of the support 3, and the installation is completed.

[0058] Embodiment 2:

[0059] Based on the above embodiment 1, Figures 1 to 4 As shown, an unlocking assembly 7 is installed in the transmission control assembly 6, and the unlocking assembly 7 can be used to control the auxiliary pressure wheel 61 to be in a high position or a low position, thereby controlling whether the transmission belt 5 is in contact with the pulley 41, thereby realizing the transmission and termination of power.

[0060] The unlocking assembly 7 includes a rotating shaft 71 rotatably mounted on the sliding column 631. A vertical avoidance hole is opened on the outer arc-shaped plate 642, and the rotating shaft 71 passes through the avoidance hole. A handle 72 for controlling the rotation of the rotating shaft 71 is fixed to the outer end of the rotating shaft 71, and a cam 73 is fixed to the middle of the rotating shaft 71. The cam 73 is located between the slide plate 641 and the baffle 633, and the far end of the cam 73 has a pair of legs.

[0061] Combination Figure 3 and Figure 4 As shown, when in use,

[0062] exist Figure 3 In the state shown, there is no force between the cam 73 and the slide plate 641. At this time, under the elastic force of the elastic member 65, the slide plate 641 moves downward, and the auxiliary pressure wheels 61 at both ends of the arc plate 642 press the transmission belt 5 toward the pulley 41, so that the transmission belt 5 and the pulley 41 are pressed tightly, thereby realizing the transmission between the transmission belt 5 and the pulley 41;

[0063] When the handle 72 is turned counterclockwise, the distal end of the cam 73 gradually contacts the slide plate 641, pushing the slide plate 641 upward; thus, the auxiliary pressure wheels 61 at both ends of the arc plate 642 move upward and leave the transmission belt 5. At this time, the transmission belt 5 no longer presses the pulley 41, thereby releasing the transmission between the transmission belt 5 and the pulley 41.

[0064] Embodiment three:

[0065] Based on the above embodiment 2, combined with Figure 6 As shown, the present invention provides a light plate conveyor. The guide rails 1 on both sides are arranged symmetrically, and the guide rails 1 are fixed on the foundation through a plurality of evenly distributed cantilever beams 8. A roller support assembly is installed at both ends of the roller 4.

[0066] When in use, first release the transmission between the transmission belt 5 and the pulley 41 through the unlocking assembly 7, and then loosen the fastening bolt 621. At this time, the support 3 can be pushed to move along the guide rail 1, and the spacing between the rollers 4 can be adjusted, thereby adjusting the conveying distance of the light plate conveyor to adapt to the conveying length required by different processes. Through this method, the entire conveyor can also be divided into multiple required transport sections, and the spacing between the rollers 4 of each transport section can also be adjusted to adapt to plates of different sizes, which greatly improves the use efficiency of the conveyor.

[0067] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
