Description

Technical Field

[0001] The invention relates to the technical field of roller beds, in particular to a novel rotating roller bed. Background Art

[0002] The rotating roller bed rotates the workpiece to achieve horizontal steering and lane change of the conveyor line. The main structure consists of a turntable and a conveyor roller bed. Both ends of the rotating roller bed and the adjacent roller beds on both sides should have safety gravity stops. The turntable and roller bed use brake motors with manual release of the brake. The turntable adopts variable frequency speed control and should have a slow-fast-slow function during operation. The supplier needs to provide timing analysis. The turntable track is made of profile bending and the base is adjustable. For example, a rotating roller bed in "CN107697594A" includes: a base, a large arc track, a small arc track and a roller bed; the large arc track and the small arc track are fixed on the base, and the two ends of the roller bed are respectively connected to the large arc track and the small arc track, and the center of the large arc track coincides with the center of the small arc track. The large arc track includes a first arc track and a plurality of first fixing frames; the first fixing frames are respectively fixed with bolts to the first arc track and the base; the small arc track includes a second arc track and a plurality of second fixing frames, and the second fixing frames are respectively fixed with bolts to the second arc track and the base. The rotating roller bed described in the present invention has a simple structure, low cost, small space occupation, fast and stable product transfer, and convenient later maintenance. However, in existing technology, roller beds are typically mounted using fixed rollers on the bottom that mate with the track. Taking a circular track as an example, a pair of rollers are fixed on either side of the roller bed to support and guide the roller bed's rotation. While this design allows for adjustment of the roller bed's rotation angle, it doesn't allow for fine-tuning in the forward, backward, or left-right directions. When the production line needs to precisely align the rotating roller bed with the end face of the adjacent fixed roller bed, the operator can only fine-tune the overall position repeatedly based on experience. This is not only time-consuming but also prone to leaving gaps between the rollers due to inadequate adjustments. Once a large gap forms between the two ends, the conveyed material may fall through the gap, affecting production efficiency and potentially causing product loss or equipment wear. Summary of the Invention

[0003] In view of the above existing problems, the present invention is proposed.

[0004] The purpose of the present invention is to solve the problem in the prior art that it is difficult to fine-tune the roller bed after it is rotated and adjusted on the track to adapt to the position of the adjacent roller bed.

A first cylinder is symmetrically provided on both sides of the upper end of the rotating seat, and the upper end of the first cylinder is hinged to the lower side of the slide bar. By adjusting the length of the first cylinder, the rotation angle of the lifting seat and the upper end of the support can be adjusted, which is convenient for adjusting the inclination angle of the roller bed.

[0007] Furthermore, the lower end of the mobile frame is sleeved on the outside of the mobile wheel, and a first motor is provided at the lower end of the mobile frame.

[0027] like Figures 1-10 As shown, the telescopic member 9 includes an inner shaft 911 and an outer shaft 912, one end of the inner shaft 911 is slidably arranged inside the outer shaft 912, and the end faces of the inner shaft 911 and the outer shaft 912 are respectively assembled and connected with the fixed block 10 and the outer rail 151, one end of the adjusting ring 152 is rotatably arranged on the outside of the end face of the outer shaft 912, and the other end is rotatably connected with the outer thread of the inner shaft 911, and a plurality of pedals 913 are distributed in an annular shape on the outside of the adjusting ring 152. By rotating the adjusting ring 152, the inner shaft 911 can be driven to move back and forth relative to the outer shaft 912, and the inner shaft 911 and the outer shaft 912 are only slidably arranged, which can drive the inner shaft 911 to slide smoothly in the outer shaft 912, thereby achieving the effect of adjusting the length of the telescopic member 9. In addition, a pedal 913 is provided, and the staff can rotate the adjusting ring 152 by stepping on the pedal 913, which is more convenient to use.

[0028] like Figures 1-10 As shown, the fixing block 10 is a hollow structure. A limiting slot 161 is provided on the top of the fixing block 10 , and a limiting block 162 is provided at the lower end of the bracket 11 to fit in the limiting slot 161 .

[0030] like Figures 1-10As shown, the bracket 11 includes a fixed frame 221 and a second cylinder 222. The lower end of the second cylinder 222 is arranged above the limit block 162. The upper end of the second cylinder 222 is hinged with a slide 223 through the fixed frame 221. The upper part of the slide 223 is slidably arranged with the rail 131.

[0032] Working principle: When adjusting the rotation of the roller bed 3, in order to ensure that the end surface of the roller bed 3 and the adjacent equipment do not block each other during the rotation process, the height of the lifting seat 6 can be adjusted in advance until the roller bed 3 is higher than the surrounding equipment. When rotating, if the center of the roller bed 3 is rotated, the lifting seat 6 can be moved above the mobile frame 2 so that the mobile frame 2 is located in the middle position of the lifting seat 6, and then the first motor 5 is driven to drive the moving wheel 4 to move on the track 1. At this time, the roller bed 3 rotates about its own center point. If the end surface of the roller bed 3 is used as the rotation point, the lifting seat 6 can be moved on the mobile frame 2 until one end of the lifting seat 6 moves to the position above the mobile frame 2. At this time, the support of the bracket 11 and the fixed block 10 is used to support the longer end of the lifting seat 6. The moving wheel 4 is driven to move on the track 1. At this time, the roller bed 3 rotates with one end. Similarly, it can be adjusted to any position of the roller bed 3 as the rotation point for rotation, and the adjustable range is greatly increased. In addition, by adjusting the roller bed 3 and the slide rail 7, the left and right position adjustment of the roller bed 3 can be realized to adapt to the surrounding equipment as much as possible. At the same time, the inclination angle of the roller bed 3 can also be adjusted. Specifically, by driving the first cylinder 134 to extend or shorten, the lifting seat 6 and one end of the roller bed 3 are driven to tilt at a certain angle, and the angle between the bracket 11 and the lifting seat 6 is fixed, and the lower end of the bracket 11 is kept vertically to the ground. After the adjustment is completed, the lifting seat 6 is adjusted to a suitable height so that its two ends are adapted to the height of adjacent equipment. Through multi-angle and multi-range adjustments, the adjacent roller beds 3 are made to fit as closely as possible.
