Description

Technical Field

[0001] This utility model relates to the field of roll material processing technology, and in particular to a roll servo feeder. Background Technology

[0002] The coil servo feeder is an automated equipment that integrates uncoiling, leveling and feeding functions. It is mainly used for the precision conveying of metal coils (such as cold-rolled steel, galvanized sheet, stainless steel, etc.) and is widely used in hardware stamping, automotive parts, electronic appliances and other fields.

[0003] In existing technologies, the roll is usually mounted on a take-up shaft or drum. During unwinding, leveling, or feeding, it may shift or scatter due to tension changes. For example, in the published document CN220702699U, "the unwinding function of the roll is realized by driving the unwinding roller to rotate through a motor. Through the cooperation of the first pulley, the transmission belt, and the second pulley, the first pressure roller and the round rod rotate counterclockwise synchronously. The counterclockwise rotation of the first pressure roller realizes the feeding of the roll. Since the unwinding speed of the roll is equal to the feeding speed of the first pressure roller, the roll is unwound and fed immediately, avoiding the accumulation of the roll." In the above structure, the roll is prone to lateral shifting or loosening during unwinding and conveying. Without a material support plate at the bottom of the roll, the roll may sag due to gravity, causing problems with the feeding of the leveling roller. Utility Model Content

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-6 A tape servo feeder includes a body 1, a tape 2, and a feeding mechanism. A shaft 3 is provided on the body 1 and passes through the body 1. A first motor 101 is connected to one end of the shaft 3, and an expansion and contraction mechanism is provided at the other end, as shown in the figure. The expansion and contraction mechanism includes a drum 8, which is slidably disposed on the shaft 3. Several sets of connecting rods 9 are axially arranged on the drum 8, and a sector plate 10 is provided on the connecting rods 9. In this embodiment, the expansion and contraction mechanism is used to fix the tape 2.

[0023] Instead of enabling the drum 8 to extend and retract radially via the connecting rod and the sector plate 10, a second motor 102 is provided at the front end of the shaft 3. The second motor 102 includes an output shaft 17, with a limit block 18 at the end of the output shaft 17. A sleeve 19 is provided on the output shaft 17, with one end of the sleeve 19 slidably mounted on the output shaft 17 and the other end of the sleeve 19 located at the front end of the shaft 3, as shown in the figure. An external thread 20 is provided on the outer wall of the front end of the shaft 3, and an internal thread 21 adapted to the external thread 20 is provided on the inner wall of the other end of the sleeve 19. The output shaft 17 is threadedly connected to the sleeve 19. When the second motor 102 rotates, the threaded transmission converts the rotational motion into axial displacement, pushing the drum 8 to slide axially along the shaft 3, thereby driving the connecting rod 9 and the sector plate 10 to extend and retract radially, thus fixing or releasing the winding 2 and achieving quick clamping.

[0024] To prevent the conveyor belt 2 from slipping or shifting during feeding, a ratchet 5 is provided on one side of the expansion and contraction mechanism. One side of the ratchet 5 is fixed to the outer wall of the machine body 1. A connecting sleeve 6 is slidably mounted on the outer wall of the ratchet 5. A pressure plate 7 is provided on one side of the connecting sleeve 6, as shown in the figure. A plate 14 is provided below the pressure plate 7, and a spring 15 is provided on the plate 14. A pawl 16, which matches the ratchet 5, is provided at the front end of the spring 15. The pressure plate 7 receives downward pressure from the spring 15 on the plate 14. The pawl 16 and the... The ratchet 5 engages to achieve one-way locking and prevent rebound. When the pressure plate 7 is at the top of the ratchet 5, it is necessary to press down on the winding 2 on the expansion and contraction mechanism to fix it. The pressure plate 7 is pushed down to the top of the winding 2 for pressing limit. When it is necessary to press down on a new winding 2, the position of the pressure plate 7 on the ratchet 5 needs to be adjusted. The pawl 16 is moved to make the spring 15 contract and slide through the connecting sleeve 6 on the outer wall of the ratchet 5 to adjust it to the top of the ratchet 5.

[0025] Furthermore, a material support mechanism is provided below the expansion and contraction mechanism. The material support mechanism includes a cylinder 11, which includes a piston rod 12. A material support plate 13 is provided on the piston rod 12. The material support plate 13 is located directly below the expansion and contraction mechanism, as shown in the figure. After the expansion and contraction mechanism locks the inner diameter of the roll 2 and clamps the roll 2, the material support plate 13 is located directly below the roll 2. By extending and retracting the piston rod 12 of the cylinder 11, the weight of the roll 2 is supported to prevent sagging or deformation. The material support plate 13 is arc-shaped to accommodate rolls of different diameters.

[0026] In this embodiment, the feeding mechanism is located on one side of the machine body. The feeding mechanism is a frame 22. A leveling mechanism is provided on the frame 22. The leveling mechanism consists of several upper rollers 23 and several lower rollers 24. The upper rollers 23 and lower rollers 24 are arranged in an alternating manner. A servo motor 25 is provided on the outside of the frame 22. The lower rollers 24 are driven by the servo motor 25. The leveling mechanism applies mechanical force to the tape roll through the alternating rollers to eliminate the bending, wave deformation and internal stress generated by the material during transportation or processing, and ensure that the material meets the flatness requirements required for subsequent stamping.

[0027] A support 26 is provided between the upper rollers 23, and several buffer springs 27 are provided above the support 26. The buffer springs 27 are used in the leveling mechanism to absorb the impact force when the rollers move, reduce equipment vibration and noise, and maintain a slight pre-pressure between the rollers to ensure that the material is subjected to uniform force during the leveling process. A connecting frame 18 is provided on the buffer spring 17, and a hydraulic cylinder 29 is provided above the connecting frame 18. The hydraulic cylinder 29 is located on the frame 22. The hydraulic cylinder 29 drives the upper rollers 23 to move up and down in the leveling mechanism. By adjusting the pressure, the leveling force is controlled to ensure that the material obtains a stable pressure output during the leveling process.

[0028] The frame includes an inlet 30 and an outlet 31. A folding arm 32 is provided on one side of the inlet 30. The folding arm 32 is used to press the end of the tape 2 into the leveling mechanism. The folding arm 32 can be controlled by a PLC to realize the action of pressing the end of the tape 2.

[0029] Working principle: The roll 2 is fixed by the expansion and contraction mechanism, the material support mechanism supports the weight of the roll to prevent sagging, the leveling mechanism eliminates material deformation through the staggered arrangement of upper and lower rollers and the pressure adjustment of hydraulic cylinder 29, and the pressure plate is fixed and adjusted by the cooperation of spring 24 and ratchet 5 to ensure stability and accuracy in the feeding process.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
