Description

Technical Field

[0001] This invention relates to the field of roll material slitting technology, and in particular to a coreless roll material slitting and nailing machine. Background Technology

[0002] A roll slitting machine (non-sticky strip) is a device that cuts and rolls large-diameter rolls of material into multiple smaller-diameter rolls, involving slitting, cutting, and packaging.

[0003] Existing technology involves using an automatic slitting device to slit rolls to a fixed length, then driving an integrated turret via a turret driver to approach the winding station. This allows the cutting device, tape pasting device, and tail roller device mounted on the integrated turret to complete the sealing of small-diameter rolls, eliminating the need for manual operation and improving sealing efficiency while removing safety hazards. However, this existing technology suffers from overly simple structure, poor reliability, and instability. For example, the tape pasting device may not achieve good tape pasting results, may not stabilize the tape pasting position, and may easily lead to pasting errors. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a coreless roll-to-nail machine for roll materials that is structurally reliable and has strong stability, in order to overcome the shortcomings of the prior art.

[0005] This invention provides a coreless roll rewinding and nailing machine, comprising: a thread-organizing device for flattening the roll; a buffer device coupled to the thread-organizing device for receiving the roll; a traction device coupled to the buffer device for advancing and unwinding the roll by clamping and traction; a winding device coupled to the traction device for receiving the roll advanced by the limiting traction device and winding the roll by rotation; a cutting device coupled to the winding device and the traction device for cutting the roll between the winding device and the traction device; and a nailing device coupled to the winding device for fixing nails at the end of the rolled roll to secure the winding effect. The beneficial effects of the above technical solution are that by integrating the wire sorting device, buffer device, traction device, winding device, cutting device, and nailing device, it can realize the function of dividing large rolls into small rolls. The buffer device can pre-unwind the roll material, effectively avoiding the defect of poor unwinding and flattening effect caused by the asynchronous operation of the traction device and the wire sorting device. The traction device can cooperate with the winding device to achieve stable and reliable feeding and cutting, effectively solving the problems of coreless winding and the inability to flatten during cutting. The winding device provides the function of coreless winding by limiting the roll material, thereby realizing a coreless winding and nailing machine with reliable structure and strong stability.

[0006] In some embodiments, the winding device includes a rotary driver, a telescopic driver, and a winding chuck. The telescopic driver drives the winding chuck to limit the winding material, and the rotary driver drives the winding chuck to rotate to achieve winding of the winding material. The beneficial effect of the above technical solution is that by using a telescopic winding chuck to achieve advance and retraction, the winding material is placed in the winding chuck, thereby realizing the coreless winding function.

[0007] In some embodiments, the nailing device includes a nailing driver, a vibratory feeder, a feeder, a pressure driver, a pressure rod, and a nailing head. The nailing driver controls the nailing head to move into the winding device. The feeder supplies nails from the vibratory feeder to the nailing head. The pressure driver drives the pressure rod to press against the surface of the roll material in the winding device to pre-fix the winding effect. The beneficial effect of the above technical solution is that by using the nailing head to attach nails to the end of the small roll of material to achieve sealing, the reliability and stability of adhesive application are greatly improved.

[0008] In some embodiments, the support platform is raised and lowered by a support actuator to support the suspended roll material as the adhesive applicator head descends to apply adhesive. The beneficial effect of this technical solution is that by actively raising the support platform to cooperate with the adhesive applicator head, it provides support for the roll material during adhesive application, greatly improving the reliability and stability of the adhesive application process.

[0009] In some embodiments, a pressure roller device coupled to the winding device is also included to limit the winding width. The pressure roller device includes a pressure roller driver and a pressure plate, the pressure plate being adjusted by the extension and retraction process controlled by the pressure roller driver to adjust the winding width. The beneficial effect of the above technical solution is that by limiting the winding width in advance through the pressure roller device, the problem of winding errors can be effectively avoided.

[0010] In some embodiments, the buffer device includes a buffer support, a fixed roller disposed on the upper part of the buffer support, and a movable roller disposed on the lower part of the buffer support. The movable roller is slidably mounted on a slide bar longitudinally disposed between the upper and lower parts of the buffer support via a slider. The beneficial effect of the above technical solution is that the buffer device uses the cooperation of the movable roller and the fixed roller to buffer a certain length of roll material.

[0011] In some embodiments, a receiving tray, coupled to the winding device, is also included to receive the slitting rolls that fall from the winding device. The beneficial effect of the above technical solution is that the receiving tray enables the collection of slitting rolls, achieving automated unloading.

[0012] In some embodiments, the traction device includes a traction driver, a slide rail, a sliding table, a chuck driver, and a traction chuck. The chuck driver is mounted on the sliding table, which is slidably mounted on the slide rail. The traction driver drives the sliding table to slide along the slide rail, while the chuck driver drives the traction chuck to clamp and release. The beneficial effect of the above technical solution is that the retraction of the coiled material after feeding is achieved by moving the traction chuck through the traction driver, thereby improving the reliability and stability of the structure.

[0027] like Figure 1 As shown, this embodiment of the invention provides a coreless roll slitting and nailing machine, which includes a wire sorting device 1, a buffer device 2, a traction device 3, a roll device 4, a cutting device 6, a nailing device 7, a pressure roller device 8, and a receiving tray 9, which respectively realize the flattening of the roll, the buffering of the roll, the traction of the roll, the slitting and rewinding of the roll, the cutting of the roll after slitting and rewinding, the nailing and sealing of the roll after slitting and rewinding, the pressure roller during slitting and rewinding, and the unloading of the roll after slitting and rewinding. This embodiment integrates a wire sorting device 1, a buffer device 2, a traction device 3, a winding device 4, a cutting device 6, and a nailing device 7 to achieve the function of dividing large rolls into smaller rolls. The buffer device 2 can pre-unwind the roll material, effectively avoiding the defect of poor unwinding and flattening effect caused by the asynchronous operation of the traction device 3 and the wire sorting device 1. The traction device 3 can work with the winding device 4 to achieve stable and reliable feeding and cutting, effectively solving the problems of coreless winding and the inability to flatten during cutting. The winding device 4 provides the function of coreless winding by limiting the roll material. Replacing the adhesive device with the nailing device 7 can solve the problem of adhesive stability, thereby realizing a coreless winding and nailing machine with reliable structure and strong stability.

[0028] like Figure 1-2As shown, the cable management device 1 of this embodiment is used for flattening the roll material. The cable management device 1 includes a cable management driver 10, a rotating shaft 11, a central mounting member 12, and several support plates 13. The several support plates 13 are radially assembled on the central mounting member 12 to form an unwinding frame. The central mounting member 12 is locked on the rotating shaft 11, and the rotating shaft 11 is controlled by the cable management driver 10 to rotate. Specifically, the central mounting member 12 is hexagonal in shape, with an inner mounting hole on each face, and each support plate 13 has an outer mounting hole. Through the assembly of the inner and outer mounting holes, a support plate 13 is mounted on each face of the central mounting member 12. The six support plates 13 are radially assembled as a whole, and the roll material is unwound by passing through the holes in the support plates 13.

[0029] like Figure 1 , 3 As shown, the buffer device 2 in this embodiment is coupled to the cable management device 1 and is used to receive the roll material. The buffer device 2 includes a buffer support 14, three sets of fixed rollers 15 disposed on the upper part of the support, and a movable roller 16 disposed on the lower part of the buffer support 14. The movable roller 16 is slidably mounted on a slide rod 18 longitudinally disposed between the upper and lower parts of the buffer support 14 via a slider 17. In this embodiment, the buffer device 2 uses the cooperation of the movable roller 16 and the fixed rollers 15 to buffer a certain length of roll material. After the roll material is released from the winding device 1, it first winds around one of the fixed rollers 15, then around the movable roller 16, and finally around the other two fixed rollers 15. During the process of the traction device 3 pulling the roll material forward, the roll material is subjected to traction force. After reaching a certain level, the movable roller 16 is lifted along the slide bar 18, so that the roll material behind the movable roller 16 can be pulled forward by the traction device 3, while the roll material in front of the movable roller 16 can be temporarily not unwound. After the movable roller 16 is lifted to a certain height, the traction device 3 stops pulling and loses the tension of the roll material on the movable roller 16. Then, the movable roller 16 descends and resets along the slide bar 18 under the action of gravity. At this time, since the roll material behind the movable roller 16 is no longer pushed forward, the movable roller 16 stretches the roll material in front of the movable roller 16 during the descent. At the same time, the winding device 1 rotates and unwinds. During the descent of the movable roller 16, the position sensor senses the height of the lifting and lowering, thereby triggering the winding device 1 to start unwinding.

[0030] like Figure 1 , 4As shown, the traction device 3 of this embodiment is coupled to the buffer device 2 and is used to advance the unwinding by clamping and traction of the roll material. The traction device 3 includes a traction driver 19, a slide rail 20, a sliding table 21, a chuck driver 22, and a traction chuck 23. The chuck driver 22 is mounted on the sliding table 21, and the sliding table 21 is slidably mounted on the slide rail 20. The traction driver 19 is used to drive the sliding table 21 to slide along the slide rail 20, while the chuck driver 22 is used to drive the traction chuck 23 to clamp and release. The chuck driver 22 includes an upper chuck driver 22 and a lower chuck driver 22, and the traction chuck 23 includes an upper chuck and a lower chuck. The upper chuck driver 22 controls the upper chuck, and the lower chuck driver 22 controls the lower chuck. The clamping and releasing of the roll material is achieved by controlling the opening and closing of the upper and lower chucks, and the upper and lower chucks are configured with an elongated shape.

[0031] At the start of traction, the traction chuck 23 is driven by the chuck driver 22 to clamp the roll material. After clamping, the traction driver 19 drives the traction chuck 23 to slide horizontally along the slide rail 20 to the rear of the roll material chuck 26 (at this time, the roll material chuck 26 has not yet extended). The roll material is in a straight state at this time. After the roll material chuck 26 extends and limits the roll material, the chuck driver 22 drives the traction chuck 23 to release the clamping of the roll material. Since the distance between the upper and lower chucks after release is greater than the outer diameter of the roll material chuck 26, the traction driver 19 resets the traction chuck 23 by passing over the roll material chuck 26 along the slide rail 20. After reset, the traction chuck 23 remains released. The next clamping time of the traction chuck 23 is after the winding is completed.

[0032] like Figure 1 , 5As shown, the winding device 4 in this embodiment is coupled to the traction device 3 and is used to receive the winding material pushed by the limiting traction device 3 and wind the winding material by rotation. The winding device 4 includes a rotary driver 24, a telescopic driver 25, and a winding chuck 26. The telescopic driver 25 is used to drive the winding chuck 26 to extend to limit the winding material and to retract it for unloading and loading. The rotary driver 24 is used to drive the winding chuck 26 to rotate to achieve winding of the winding material. In this embodiment, the advance and retraction are achieved through the telescopic winding chuck 26, and the winding material is placed in the winding chuck 26, thereby realizing the coreless winding function. The coil chuck 26 consists of two semi-circular rollers with a gap between them. This gap accommodates the coil material being fed. The direction of the gap aligns with the direction of the coil material, allowing it to smoothly enter and thus limiting its position. This limiting can be achieved in two ways: First, the semi-circular rollers rotate and wind up while maintaining the gap. Since the portion of the coil material gripped by the traction device 3 during feeding is located behind the coil chuck 26, a certain length of coil material remains between this gap and the traction end. During the rapid rotation of the coil chuck 26, the coil material can be quickly positioned. Second, to enhance the positioning of the coil material, an inclined guide seat can be used. As the two semi-circular rollers extend, the inclined guide seat causes them to move closer together, reducing the gap until the coil material is clamped and positioned.

[0033] like Figure 1 , 6 As shown, the cutting device 6 in this embodiment is coupled to the winding device 4 and the traction device 3, and is used to cut the rolled material located between the winding device 4 and the traction device 3. The cutting device 6 includes a cutting driver 33, scissors 34, and a scissors 34 driver. The cutting driver 33 drives the scissors 34 to extend during cutting and retract after cutting. During cutting, the traction device 3 clamps and positions the rolled material, and the nailing device 7 also clamps and positions the rolled material.

[0034] like Figure 1 , 7As shown, this embodiment includes a nail driver 27, a vibratory feeder 32, a feeder 31, a pressure driver 28, a pressure rod 30, and a nail head 29. The nail driver 27 controls the movement of the nail head 29 into the winding device. The feeder 31 supplies nails from the vibratory feeder 32 to the nail head 29. The pressure driver 28 drives the pressure rod 30 to press against the surface of the roll material in the winding device to pre-fix the winding effect. In this embodiment, the nail head 29 is used to attach nails to the end of the small roll of material to achieve sealing, greatly improving the reliability and stability of adhesive application. After the winding device has wound up to a certain extent, winding stops, the pressure roller device 8 is released, the pressure drive 28 drives the pressure rod 30 to move and press against the surface of the roll material, and then the shearing device cuts the material. The feeder 31 picks up the material from the vibrating plate 32 and sends the nail to the nail head 29. After receiving the nail, the nail head 29 is driven by the nail driver 27 to move to the surface of the roll material and nail it onto the roll material. Subsequently, the nail head 29, the pressure rod 30, and the roll clamp are reset, and the nailed roll material falls into the receiving tray.

[0035] like Figure 1 , 8 As shown, the pressure roller device 8 in this embodiment is coupled to the winding device 4 and is used to limit the winding width. The pressure roller device 8 includes a pressure roller driver 43 and a pressure plate 44. The pressure plate 44 is controlled by the pressure roller driver 43 to adjust the winding width by controlling the extension and retraction process. After winding is completed, the pressure plate 44 opens to allow space for the nailing device 7 to advance. This embodiment effectively avoids winding errors by limiting the winding width in advance through the pressure roller device 8.

[0036] like Figure 1 As shown, the receiving tray 9 in this embodiment is coupled to the winding device 4 and is used to receive the slitting rolls that fall from the winding device 4. This embodiment uses the receiving tray 9 to collect the slitting rolls, thus achieving automated unloading.

[0037] The working principle of this invention embodiment: The roll material is flattened in the winding device 1, and manually stretched through the buffer device 2 to the forward traction device 3. The traction device 3 is activated to clamp the roll material and pull it forward to the rear of the roll material clamp 26. The roll material clamp 26 extends to limit the roll material. After limiting, the traction clamp 23 releases the clamp on the roll material and resets. The pressure head 30 extends to contact the surface of the roll material clamp 26, and the roll material clamp 26 starts to rotate to wind up. After winding to the preset length, the roll material clamp 26 stops rotating. The guiding device 3 is activated to clamp the roll material, the pressure roller device is activated to open the pressure plate, and then the nailing device 7 is activated to first control the movement of the pressure rod 30 and press against the roll material to pre-fix it. After pre-fixing, the roll material clamp rotates a certain distance and then stops to shorten the length of the roll material at the rear end of the nailing position. Then, the feeder 31 sends the nails from the vibrating plate 32 to the nailing head 29. The nailing head 29 moves forward to fix the nails on the surface of the roll material. Then, the nailing head 29 and the pressure rod 30 are reset, the roll material clamp 26 is retracted, and the slit rolls fall onto the receiving tray 9. Generally speaking, the first roll is not considered a finished product, and the second roll and the next rolls are considered finished products after slitting.

[0038] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
