Description

Technical Field

[0001] This utility model relates to the technical field of knife-coated fabric winding machines, specifically an adjustment mechanism for a knife-coated fabric winding machine. Background Technology

[0002] The knife-coated fabric rewinding machine is a key piece of equipment used in the rewinding process of knife-coated fabric production. Its main function is to uniformly and flatly rewind the coated and dried knife-coated fabric substrate (such as PVC knife-coated fabric, PVDF knife-coated fabric, etc.) into a roller-shaped finished product according to the set length and roll diameter requirements, so as to facilitate storage, transportation and subsequent processing.

[0003] The main winding process involves the fabric being drawn from the unwinding unit, its tension and trajectory adjusted by the guide roller system to ensure it enters the winding station flat and without deviation. The winding shaft drives the paper tube core to rotate, and the fabric is evenly wound around the paper tube core, completing the winding process. However, due to size mismatches between the paper tube core and the winding shaft, or machining errors in the paper tube core, there may be a certain dimensional deviation between the winding shaft and the paper tube core, leading to the following structural issues: 1. If the inner diameter of the paper tube core is larger than the outer diameter of the winding shaft (excessive gap), the winding shaft will not... 1. The method effectively drives the core to rotate through friction, causing the core to slip and spin freely during the winding process, or even fall off the shaft due to vibration or tension fluctuations. When slipping, the fabric loosens instantly, which may cause large-area wrinkles or stacking. 2. If the winding shaft is designed with a fixed size (such as only suitable for Φ76mm cores), when Φ68mm or Φ70mm cores are needed, they cannot be installed or supported due to size deviations. This results in the equipment being able to produce only a single specification of product, losing flexibility. When customer needs are diversified, multiple winding machines of different specifications need to be purchased, increasing equipment investment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustment mechanism for a knife-coated fabric winding machine, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustment mechanism for a knife-coated fabric winding machine, comprising a base frame and a support plate fixed to the top of the base frame. A motor is fixedly installed at the end of the support plate, and the output end of the motor passes through the support plate and is fixedly connected to a drive rod. One end of the drive rod is fixedly connected to a turntable. The circumferential sidewall of the turntable has three circumferentially evenly distributed sliding grooves. A slider is slidably connected inside the sliding groove. One end of the slider is located outside the sliding groove and is fixedly connected to an arc-shaped inner support bar. The arc-shaped inner support bar is perpendicular to the slider. Multiple sliders can slide synchronously inside their respective sliding grooves.

[0008] Preferably, a drive disk is rotatably sleeved on the drive rod, and an arc-shaped opening is formed through the surface of the drive disk. A drive shaft is fixedly connected to the side of the slider near the support plate, and the drive shaft passes through the arc-shaped opening. A through-hole is formed on the surface of the drive disk, and the drive rod passes through the through-hole.

[0009] Preferably, the drive disk has a screw hole on its surface, and a bolt is movably inserted into the screw hole, with the threaded end of the bolt threaded into the screw hole.

[0013] (III) Beneficial Effects

[0014] This utility model provides an adjustment mechanism for a knife-coated fabric winding machine, which has the following beneficial effects:

[0015] 1. In this utility model, the rotating drive disk rotates, causing the arc-shaped opening to cooperate with the drive shaft, thereby driving the slider to move linearly. This causes the slider to drive the arc-shaped inner support strip to move, so that the arc-shaped surface of the arc-shaped inner support strip fully contacts the inner wall of the paper tube, increasing the contact area and improving the friction. This allows multiple arc-shaped inner support strips to effectively drive the paper tube to rotate through friction, preventing the paper tube from slipping and spinning during the knife-scraping and winding process, thus improving the winding efficiency.

[0016] 2. In this utility model, multiple arc-shaped inner support bars are adjustable within a small range to match the internal dimensions of the paper tube, thus avoiding the problem that the equipment can only produce a single specification of product and loses flexibility due to size deviations that prevent installation or support.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 , Figure 7 This utility model provides a technical solution: an adjustment mechanism for a knife-coated fabric winding machine, including a base frame 1 and a support plate 2 fixed to the top of the base frame 1. A motor 3 is fixedly installed at the end of the support plate 2. The output end of the motor 3 passes through the support plate 2 and is fixedly connected to a drive rod 4. One end of the drive rod 4 is fixedly connected to a turntable 5. The circumferential sidewall of the turntable 5 has three circumferentially evenly distributed sliding grooves 501. A slider 10 is slidably connected inside the sliding groove 501. One end of the slider 10 is located outside the sliding groove 501 and is fixedly connected to an arc-shaped inner support bar 9. The arc-shaped inner support bar 9 is perpendicular to the slider 10. Multiple sliders 10 can slide synchronously inside the corresponding sliding groove 501.

[0027] When performing the winding operation, the paper tube 13 is first placed on multiple arc-shaped inner support bars 9, and then adjusted so that the arc-shaped inner support bars 9 tighten the inner wall of the paper tube 13. After completion, the motor 3 is started, which drives the drive rod 4 and the turntable 5 to rotate. The turntable 5 drives the paper tube 13 to rotate through the arc-shaped inner support bars 9, so that the paper tube 13 winds up the knife-coated cloth.

[0028] See Figure 3 and Figure 5A drive disc 7 is rotatably mounted on the drive rod 4. An arc-shaped opening 701 is provided through the surface of the drive disc 7. A drive shaft 11 is fixedly connected to the side of the slider 10 near the support plate 2. The drive shaft 11 is provided through the arc-shaped opening 701. A through-hole 702 is provided on the surface of the drive disc 7. The drive rod 4 is provided through the through-hole 702.

[0029] Furthermore, before the winding blade scrapes the cloth, the paper tube 13 needs to be placed on multiple curved inner support strips 9. At this time, there may be gaps, which will affect the winding and need to be adjusted.

[0030] The position adjustment process of the arc-shaped inner support bar 9 is as follows: by rotating the drive disk 7, the arc-shaped opening 701 is engaged with the drive shaft 11, that is, the drive shaft 11 is squeezed, thereby driving the slider 10 to move linearly inside the slide groove 501, so that the slider 10 drives the arc-shaped inner support bar 9 to move, so that the arc-shaped surface of the inner support bar 9 is fully in contact with the inner wall of the paper tube 13, increasing the contact area and improving the friction. This allows multiple arc-shaped inner support bars 9 to effectively drive the paper tube 13 to rotate through friction, preventing the paper tube 13 from slipping and spinning during the knife-scraping and winding process, and improving the winding efficiency.

[0031] See Figure 3 and Figure 6 The drive disk 7 has a screw hole 703 on its surface, and a bolt 8 is movably inserted into the screw hole 703, with the threaded end of the bolt 8 threaded into the screw hole 703.

[0032] After adjusting the position of the arc-shaped inner support bar 9, it is necessary to lock its position. This is done by rotating the bolt 8 so that the threaded end of the bolt 8 abuts against the side wall of the turntable 5, thereby locking the angle of the drive disc 7 and ultimately locking the position of the multiple arc-shaped inner support bars 9.

[0033] See Figure 7 A stop bar 12 is fixedly connected to the end of the slider 10, and the stop bar 12 is located outside the arc-shaped inner support bar 9.

[0034] The purpose of setting the baffle 12 is to limit the edge of the paper tube 13, that is, to make the edge of the paper tube 13 contact the baffle 12 when the paper tube 13 is installed.

[0035] See Figure 3 A retaining ring 6 is coaxially fixedly connected to the drive rod 4, and the retaining ring 6 is located on one side of the drive disc 7.

[0036] The purpose of setting the retaining ring 6 is to limit the drive disk 7 between the retaining ring 6 and the turntable 5, so that the drive disk 7 will not fall off and can rotate smoothly.

[0037] See Figure 5The slide groove 501 is cross-shaped, and the cross section of the slider 10 is also cross-shaped, ensuring that the slider 10 can move linearly inside the slide groove 501 without detaching. The slide groove 501 plays a limiting role for the slider 10.

[0038] It should be noted that the knife-coated fabric winding machine is a specialized device used to evenly and smoothly wind knife-coated fabric onto a paper tube or mandrel. The following is an analysis of its main structure and function: unwinding and traction unit (supporting the unprocessed knife-coated fabric roll and releasing the fabric via a motor or passive roller), correction and guiding unit (detecting the fabric edge via infrared or visual sensors), and winding unit; this application focuses on improvements to the winding unit, and the other parts are not the focus of this application and therefore do not require detailed description.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
