Description

Technical Field

[0001] This utility model relates to the technical field of tower tray winding machine. Background Technology

[0002] After the wide roll film is produced, it is usually cut according to specific size requirements, and then the cut film is rolled up. Specifically, the roll can be fitted onto the film bearing in the winding device, and the power structure of the winding device drives the roll to rotate through the film bearing to complete the winding operation.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0031] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0032] like Figure 1-5 As shown, the tray winding machine of this embodiment includes: a frame 100; winding units 200 connected to the frame 100 for winding and coiling slit materials, wherein a plurality of units are provided, and the number of units is not less than the number of slit materials; and guide units 300 disposed between the frame 100 and the winding units 200, corresponding one-to-one with the winding units 200, for guiding the slit materials into the winding units 200; the winding unit 200 includes a drive shaft 210 rotatably connected to the frame 100, wherein the axis of the drive shaft 210 is perpendicular to the material transport direction, and the frame 100 is provided with a drive assembly 110 for driving the drive shaft 210 to rotate.

[0033] With this design, the number of winding units is no less than the amount of material after slitting, and each unit is driven independently by a drive shaft. When a winding error occurs in one unit (such as material breakage or winding misalignment), it will not affect the normal operation of other units. Compared with the traditional design where multiple stations on the same winding shaft interfere with each other, this structure can avoid the situation of "one failure leading to all failures," significantly improving the fault tolerance of the equipment in the production process and reducing overall downtime losses caused by local failures.

[0034] The guide units are configured one-to-one with the number of winding units, and each guide unit is only responsible for the material input of the corresponding winding unit. This "one-to-one" design can avoid path intersection or interference when multiple materials are transported, and ensure that each slit material can accurately enter the corresponding winding unit along an independent guide path, avoiding winding chaos caused by material misalignment, and improving the stability of the winding process and the finished product qualification rate.

[0035] According to one embodiment of the present invention, the guiding unit 300 includes a feed roller 310 and a discharge roller 320 rotatably disposed. The axis directions of the feed roller 310 and the discharge roller 320 are parallel to the axis direction of the drive shaft 210. The feed roller 310 is disposed adjacent to the surface of the frame 100, and the discharge roller 320 is disposed adjacent to the middle section of the drive shaft 210.

[0036] With this design, the material can be wound and rolled up in the middle of the roll.

[0037] According to one embodiment of the present invention, the guide unit 300 further includes a plurality of transition rollers, which are disposed between the feed roller 310 and the discharge roller 320. The transition rollers are used to displace the material in the axial direction of the drive shaft 210.

[0038] This design enables the transfer of materials.

[0039] According to one embodiment of the present invention, the transition roller includes a first transition roller 330, a second transition roller 340, and a third transition roller 350 arranged sequentially along the material conveying direction. The axis of the first transition roller 330 is parallel to the axis of the drive shaft 210, and the axes of the second transition roller 340 and the third transition roller 350 are perpendicular to the axis of the drive shaft 210. The projections of the first transition roller 330 and the second transition roller 340 on the horizontal plane have overlapping portions, and the projections of the third transition roller 350 and the discharge roller 320 on the horizontal plane have overlapping portions.

[0040] This design enables the reversible transport of materials.

[0041] According to one embodiment of the present invention, the frame 100 is fixedly provided with an extension column 120, and the extension column 120 is provided with a mounting frame 130. The third transition roller 350 and the discharge roller 320 are rotatably connected to the mounting frame 130.

[0042] This design enables the installation of the third transition roller and the discharge roller.

[0043] According to one embodiment of the present invention, a first adjusting component 400 for adjusting the height of the feed roller 310 is provided between the feed roller 310 and the frame 100.

[0044] With this design, the contact angle of the material as it enters the transition roller changes accordingly after the height of the feed roller is adjusted. A reasonable contact angle can reduce frictional loss of the material during the transition process, avoid wrinkling or stretching deformation of the material due to angle deviation, and thus improve the surface quality of the wound product.

[0045] Different production processes have different requirements for the initial tension of the material (e.g., high-speed winding requires increased tension to ensure compactness). Adjusting the height of the feed rollers can indirectly adjust the initial tension of the material in the guiding unit. This flexibility allows the equipment to adapt to diverse production processes and improves its versatility.

[0046] According to one embodiment of the present invention, the first adjustment component 400 includes an adjustment rod 410 that rotates with damping relative to the frame 100. The rotation axis of the adjustment rod 410 is parallel to the axis of the drive shaft 210. The feed roller 310 is rotatably connected to the adjustment rod 410.

[0047] With this design, the height of the feed roller can be adjusted by rotating the adjusting rod to the optimal angle.

[0048] According to one embodiment of the present invention, the frame 100 is provided with two sets of limiting members 140, and the adjusting rod 410 is rotatably disposed between the two sets of limiting members 140.

[0049] This design avoids excessive adjustment force or material tension, which could cause the adjustment rod to rotate excessively and affect the normal transmission of the production line.

[0050] According to one embodiment of the present invention, the drive shaft 210 is fitted with a reel, and the winding unit 200 further includes a pressing component 500 for pressing the slit material against the reel.

[0051] This design ensures the proper winding and rewinding of the slit material.

[0052] According to one embodiment of the present invention, the pressing assembly 500 includes an extension rod 510 and a pressing roller 520 rotatably connected to the extension rod 510. The material is clamped between the pressing roller 520 and the roll. The extension rod 510 is rotatably connected to the mounting frame 130. The axial directions of the pressing roller 520 and the extension rod 510 are parallel to the axial direction of the drive shaft 210.

[0053] According to one embodiment of the present invention, a second adjustment component for adjusting the downward pressure of the pressure roller 520 is provided between the extension rod 510 and the mounting frame 130.

[0054] This design addresses the varying requirements for winding performance in different production scenarios (e.g., packaging films require loose winding, while industrial materials require tight winding). The second adjustment component allows for flexible adjustment of the downward pressure of the pressure roller: increasing the pressure results in tighter winding, while decreasing the pressure leads to looser winding. This adjustability enables the equipment to adapt to diverse materials and process requirements, avoiding production limitations caused by a single function and improving the equipment's versatility and production flexibility.

[0055] According to one embodiment of the present invention, the second adjustment component includes a torsion spring 530, a pressing rod 511 fixedly disposed on the extension rod 510, and an adjustment plate 131 fixedly disposed on the mounting bracket 130. The adjustment plate 131 is provided with a plurality of pressing posts 132. The first torsion arm 531 of the torsion spring 530 abuts against the pressing rod 511, and the second torsion arm 532 of the torsion spring 530 abuts against the pressing posts 132.

[0056] With this design, the pressure roller can be used to achieve the purpose of pressing by utilizing the elastic force of the torsion spring, resulting in a simple structure and low cost.

[0057] According to one embodiment of the present invention, the pressing rod 511 is provided with a groove 512 that limits and cooperates with the first torsion arm 531.

[0058] With this design, the groove and the first torsion arm of the torsion spring form a locking and limiting structure. When the downward pressure of the pressure roller is adjusted by the second adjusting component, the first torsion arm will be embedded in the groove, and the geometry of the groove will limit the axial displacement of the torsion spring. This design can prevent the first torsion arm from shifting due to vibration or material tension fluctuations during equipment operation, avoid the downward pressure from shifting, ensure that the pressure of the pressure roller on the material remains stable, and thus ensure the consistency of the winding tension.

[0059] According to one embodiment of the present invention, the second torsion arm 532 is provided with an operating protrusion 533 for easy operation.

[0060] This design provides the operator with a direct point of force application, allowing them to manually rotate the second torsion arm of the torsion spring without the need for additional tools (such as wrenches or screwdrivers). When adjusting the downward pressure of the pressure roller, the operator can quickly adjust the angle of the second torsion arm by holding or moving the operating rod, shortening operation time and improving production efficiency.

[0061] According to one embodiment of the present invention, a plurality of the pressure columns 132 are evenly distributed in an arc shape.

[0062] This design allows for standardized adjustment scales by evenly distributed pressure columns. Operators can quickly find the appropriate pressure position by matching the preset adjustment range to the material specifications, without complex calculations. This "scaled" design lowers the operational threshold, making it particularly suitable for simultaneous debugging of multiple devices in mass production or for novice operators to quickly get started.

[0063] According to one embodiment of the present invention, the mounting bracket 130 is provided with a clearance groove 133, which is used to avoid interference with the rotation of the extension rod 510.

[0064] According to one embodiment of the present invention, the mounting bracket 130 is provided with a pressing protrusion 134, which abuts against the extension rod 510. The pressing protrusion 134 is used to prevent the pressing roller 520 from applying excessive force to the drive roller.

[0065] This design allows the pressure-blocking protrusions to limit sudden changes in pressure on the pressure rollers caused by operator misadjustment (such as excessive rotation of the torsion spring) or equipment vibration, thus preventing sudden mechanical failures or material damage during production. This structural design provides physical safety protection for the equipment, reduces downtime caused by uncontrolled pressure, ensures a stable and controllable winding process, and lowers production risks.

[0066] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
