Description

Technical Field

[0001] This utility model relates to the technical field of waste material winding, specifically a vertical waste material winding device for a slitting machine. Background Technology

[0002] Before steel coils are formally processed into various profiles, they need to undergo a series of slitting processes according to the needs of the profiles. During the production process, waste material may be generated near the edges of both sides of the steel strip. As the production line continues to operate, the waste material needs to be collected in a timely manner using a coiler for subsequent recycling and transportation. When using a motor to drive the take-up roller for winding, as the waste material roll increases in size, the winding length is relatively large when the motor rotates once. If this is not matched with the speed of the slitting machine, it is easy to cause a pulling phenomenon on the steel coil in the slitting state, which can easily lead to cutting deviation. In order to facilitate material handling, the existing take-up shaft is suspended on one side. When the mass of the waste material roll is large, it is easy to cause deformation of the take-up shaft. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a vertical waste material winding device for slitting machines.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a vertical waste material coiling device for a slitting machine, comprising a frame, two parallel feeding rollers on the upper part of the frame, and a coiling roller on the lower part of the frame. A waste material tension adjusting mechanism is located between the coiling roller and the feeding roller on the frame, and the waste material tension adjusting mechanism is mounted on a horizontal frame. The horizontal frame has a through groove for transverse movement, and a sliding block that slides along the through groove is located within the through groove. A rotating roller is mounted on the sliding block, and limiting blocks are located on both sides of the sliding block at the through groove. A spring is mounted on one side of the sliding block and the through groove.

[0006] The frame is equipped with multiple support rollers at the front end of the feeding roller for supporting waste material;

[0007] The frame is provided with a support mechanism for supporting both ends of the take-up roller, and a drive shaft connected to the shaft end of the take-up roller is mounted on the frame via a bearing seat.

[0008] As a preferred embodiment of this utility model, the support mechanism includes a base frame disposed at the bottom of the frame, and two vertically upward support frames are provided on the base frame. The top of the support frame is provided with an inwardly recessed groove, and an anti-wear pad is installed in the groove. The anti-wear pad is provided with an installation groove for the two shaft ends of the take-up roller to be inserted. The bottom side of the installation groove is provided with a ball bearing. A pressure block is bolted to the top of the anti-wear pad, and the pressure block is provided with a mating groove for the two shaft ends of the take-up roller to mate. The pressure block is bolted to the top of the anti-wear pad.

[0009] As a preferred embodiment of this utility model, the winding roller is provided with a connecting flange at its shaft end, and the shaft end of the transmission shaft is connected to a mating flange that mates with the connecting flange via a universal coupling, and the connecting flange and the mating flange are fixed together by bolts.

[0010] As a preferred technical solution of this utility model, the frame is equipped with a variable frequency motor that drives the transmission shaft to rotate.

[0011] As a preferred embodiment of this invention, a tension sensor is provided at the bearing of the rotating roller.

[0012] As a preferred technical solution of this utility model, the frame is also provided with a frequency converter, and the tension sensor and the frequency converter motor are both connected to the frequency converter. The frequency converter is used to adjust the output power of the frequency converter motor according to the tension of the waste material detected by the tension sensor.

[0013] The beneficial effects of this utility model are:

[0014] 1. This vertical waste material coiling device for slitting machines features a waste material tension adjustment mechanism between the coiling roller and the feeding roller. This tension adjustment prevents excessive tension and deviation during winding. The sliding block can move along the chute to adjust the position of the rotating roller, thereby adjusting the effective length of the waste material within the waste material tension adjustment mechanism. This prevents the waste material roll from becoming too large, resulting in a larger winding length per motor revolution. If this length is not matched to the slitting machine speed, it can easily cause pulling on the slitting coil, thus achieving an automatic adjustment function. Furthermore, the frame is equipped with a support mechanism to support both ends of the coiling roller, preventing deformation of the coiling roller due to excessive waste material mass.

[0015] 2. This type of vertical waste material coiling device for slitting machines uses a special support mechanism to support both ends of the take-up roller. The use of ball bearings facilitates rotation and has the advantages of easy disassembly and installation.

[0016] 3. In this type of vertical waste material coiling device for slitting machines, a tension sensor is installed at the bearing of the rotating roller, and a frequency converter is also installed on the frame. The tension sensor and the frequency converter motor are both connected to the frequency converter controller. The frequency converter controller is used to adjust the output power of the frequency converter motor according to the tension of the waste material detected by the tension sensor. This dynamically adjusts the rotation speed of the coiling roller to avoid speed mismatch and pulling phenomenon on the steel coil in the slitting state. Attached Figure Description

[0026] Example: Figure 1-6 As shown, this utility model discloses a vertical waste material winding device for a slitting machine, comprising a frame 1, two parallel feeding rollers 2 on the upper part of the frame 1, and a winding roller 3 below the frame 1. A waste material tension adjusting mechanism 4 is provided between the winding roller 3 and the feeding rollers 2 on the frame 1, and the waste material tension adjusting mechanism 4 is provided on a horizontal frame 6 on the frame. The horizontal frame 6 is horizontally arranged and has a through groove 8 for transverse arrangement. A sliding block 9 is provided inside the through groove 8 and slides along the through groove 8. A rotating roller 10 is installed on the sliding block 9. Limiting blocks 11 are provided on both sides of the through groove of the sliding block 9. A spring 7 is installed on one side of the sliding block 9 and the through groove.

[0027] The frame 1 is provided with multiple support rollers 5 at the front end of the feeding roller 2 for supporting waste materials;

[0028] The frame 1 is equipped with a support mechanism 12 for supporting both ends of the take-up roller 3, and a drive shaft 13 connected to the shaft end of the take-up roller 3 is mounted on the frame 1 via a bearing seat 1. A waste material tension adjustment mechanism 4 is provided between the take-up roller 3 and the feed roller 2 to adjust the tension and prevent excessive tension during winding, thus avoiding deviation. The sliding block 9 can move along the chute to adjust the position of the rotating roller 10, thereby adjusting the effective length of the waste material within the waste material tension adjustment mechanism 4. This prevents the waste material roll from becoming too large, resulting in a larger winding length per motor revolution. If this length is not matched with the slitting machine speed, it can easily cause pulling on the steel coil in the slitting state, thus achieving an automatic adjustment function. Furthermore, the frame 1 is equipped with a support mechanism 12 for supporting both ends of the take-up roller 3 to prevent deformation of the take-up roller 3 due to excessive waste material mass.

[0029] The support mechanism 12 includes a base frame 14 at the bottom of the frame 1, with two vertically upward support frames 15 on the base frame 14. The top of each support frame 15 has an inwardly recessed groove 16, within which an anti-wear pad 17 is installed. The anti-wear pad 17 has mounting grooves 18 for inserting the two shaft ends of the take-up roller 3, and ball bearings 19 are located on the bottom side of the mounting grooves 18. A pressure block 20 is bolted to the top of the anti-wear pad 17, and the pressure block 20 has mating grooves 21 for engaging the two shaft ends of the take-up roller 3. The pressure block 20 is bolted to the top of the anti-wear pad 17. This specially designed support mechanism 12 supports both ends of the take-up roller, and the ball bearings 19 facilitate rotation and provide advantages for disassembly and assembly.

[0030] The winding roller 3 has a connecting flange 26 at its shaft end, and the drive shaft 13 has a connecting flange 22 that mates with the connecting flange 26 via a universal coupling 27. The connecting flange 26 and the connecting flange 22 are fixed together by bolts and rotated via the universal coupling 27, which provides good installation versatility.

[0031] The frame 1 is equipped with a variable frequency motor 23 that drives the drive shaft 13 to rotate. A tension sensor 24 is installed at the bearing of the rotating roller 10. The frame 1 is also equipped with a variable frequency controller 25. Both the tension sensor 24 and the variable frequency motor 23 are connected to the variable frequency controller 25. The variable frequency controller 25 adjusts the output power of the variable frequency motor 23 based on the tension of the waste material detected by the tension sensor 24. This dynamically adjusts the rotation speed of the winding roller, preventing speed mismatch and pulling phenomena on the steel coil in the slitting state.

[0032] During operation, this vertical waste material coiling device for a slitting machine has a waste material tension adjustment mechanism 4 between the coiling roller 3 and the feeding roller 2. This tension adjustment prevents excessive tension and deviation during winding. The sliding block 9 can move along the chute to adjust the position of the rotating roller 10, thereby adjusting the effective length of the waste material within the waste material tension adjustment mechanism 4. This prevents the waste material roll from becoming too large, resulting in a larger winding length per motor revolution. If this length is not matched with the slitting machine speed, it can easily cause pulling on the steel coil in the slitting process, thus achieving an automatic adjustment function. In addition, the frame 1 is equipped with a support mechanism 12 for supporting both ends of the coiling roller 3, preventing deformation of the coiling roller 3 due to the large mass of the waste material roll.
