Description

Technical Field

[0001] This invention relates to a right-angle turning machine, and more particularly, to a speed-regulating roller type right-angle turning machine that is easy to clean and maintain. Background Technology

[0002] A roller-type right-angle turning machine is a device used for turning and guiding materials during transportation. While speed regulation is typically achieved by controlling the motor speed, which is convenient, the roller surface of current roller-type right-angle turning machines tends to accumulate excessive impurities over time. These impurities affect the friction of the roller surface, thus hindering material conveying. The roller needs to rotate through friction to effectively turn and convey materials; however, excessive impurities on the roller surface lead to insufficient friction, causing materials to slip on the roller. This not only affects the material's turning direction but also causes scratches on the material's surface due to slippage and friction. Current common cleaning methods include... While cleaning the turning machine by having operators use handheld water guns to directly clean it in the area where it is placed can remove impurities from the roller surface, the machine remains unusable after rinsing due to water stains. Furthermore, the area remains wet, and operators stepping on it before the ground is completely dry makes the work area even dirtier. The length of time spent cleaning also affects downtime, significantly impacting transport efficiency. Moreover, besides cleaning and maintenance, replacing parts also involves extended downtime.

[0003] Therefore, those skilled in the art are dedicated to providing a roller-type right-angle turning machine that can effectively solve the above-mentioned technical problems and is easy to adjust in speed. Summary of the Invention

The positioning frame and the lifting guide unit slide through the base plate and move out through the pull-out inlet. The first fixed frame has an opening.

[0007] Furthermore, the roller includes an outer cylinder and an inner cylinder. The outer cylinder and the inner cylinder are flush at both ends. The inner cylinder has positioning grooves at both ends. The outer wall of the inner cylinder is connected to the inner wall of the outer cylinder through a number of support seats. The two sides of each support seat are flush with the two sides of the inner cylinder. The support seats are arranged in a circular array around the center line of the inner cylinder, and the cross-section gradually decreases from the top and bottom ends to the middle.

[0008] Furthermore, each of the inner cylinders has a cavity inside, the cavity is connected to the positioning groove, a locking mechanism is provided in the cavity, the locking mechanism is connected to one end of the connecting shaft, and the connecting shaft is detachably connected to the positioning frame.

[0010] Furthermore, the positioning frame includes several positioning blocks, the inner side of each positioning block is connected to one end of the connecting shaft, the upper end of the positioning block on the same side is connected to a side plate, the lower half of the side plate is provided with several sprockets, each sprocket is connected by a chain, a motor is provided on the side plate through a motor mounting seat, the motor is used to drive the sprockets to rotate, and the rotation of the sprockets drives the roller to rotate, and the lower end of the positioning block is connected to the upper end of the lifting plate.

[0011] Furthermore, an extension seat is provided on the inner side of the first fixing frame, and a plurality of guide grooves are provided on the inner side of the extension seat and the inner side of the second fixing frame.

[0016] The beneficial effects of this invention are as follows: This invention can drive the lifting plate downwards using a lifting cylinder, allowing the positioning frame to be removed from the guide groove through the opening. Then, a new or cleaned roller can be installed for use. This invention not only effectively reduces the weight of the roller, but also allows for quick and tool-free disassembly for cleaning, maintenance, or replacement. Specifically, the hanging ring is pressed downwards, and the main hook moves downwards, thereby separating the main hook from the auxiliary hook and allowing the roller to be removed. This shortens downtime and effectively avoids long downtime for maintenance, which affects transmission efficiency. It also has the advantages of easy assembly, simple operation, durability, and low manufacturing cost. Attached Figure Description
