Description

Technical Field

[0001] This utility model relates to the field of tape winding technology, and in particular to a tape winding device and winding system. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Strip winding involves connecting one end of the strip to a drum, rotating the drum and moving it axially to wind the strip around it, resulting in a spiral winding pattern. This spiral winding is characterized by its tight and compact nature, thus maximizing the use of the drum's space and allowing for the formation of thicker rolls.

[0004] Currently, during the material strip winding process, the direction of the axial movement of the barrel needs to be changed at the alternation point between the upper and lower layers of material strip. Since the contact surface between the material strip and the barrel is an arc, when the axial movement direction of the barrel changes, the material strip is prone to deformation and cannot completely overlap with the material strip of the upper layer. When the deformation is severe, the material strip will be twisted, resulting in defective products. When there are many layers, there is a risk of edge collapse, which will lead to the scrapping of the material roll. Utility Model Content

[0005] Based on the above analysis, this utility model aims to provide a strip winding device and winding system to solve the problem in the prior art where changing the direction of the material cylinder's axial movement during strip winding causes strip deformation, affecting product quality.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] In a first aspect, this utility model provides a strip winding device, including at least one material cylinder and a straight cylinder disposed inside the material cylinder. The material cylinder is used to wind the material strip, and the straight cylinder is connected to the material cylinder and is used to drive the material cylinder to rotate and move in the axial direction.

[0008] The material cylinder includes a flat portion and an arc-shaped portion, the flat portion and the arc-shaped portion are connected to form a closed structure, and multiple layers of material strips are wound on the material cylinder. The alternation points of the upper and lower layers of material strips are located on the flat portion, and the material cylinder can change the direction of axial movement at the alternation points.

[0009] Furthermore, the number of the planar portions is two, and the planar portions are parallel to each other and have the same projection in the vertical direction.

[0010] Furthermore, there are two arc-shaped portions, and the two arc-shaped portions connect the two planar portions to form a closed structure.

[0011] Furthermore, the two planar portions are symmetrical about the centerline of the arcuate portion.

[0012] Furthermore, the arc-shaped portion is semi-circular, and the inner diameter of the arc-shaped portion is equal to the distance between the planar portions.

[0013] Furthermore, the straight cylinder is a cylindrical shape with a cavity, and the straight cylinder is disposed between the two planar portions and is tangent to the planar portions.

[0014] Furthermore, the length of the planar portion is greater than or equal to the diameter of the straight cylinder.

[0015] Furthermore, it also includes a baffle that can be connected to the straight cylinder and is used to fix the material strip.

[0016] Furthermore, the baffle is circular, and the diameter of the baffle is greater than or equal to the height of the material strip after the material cylinder is wound.

[0017] Secondly, this utility model provides a material strip winding system, including the aforementioned material strip winding equipment.

[0018] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0019] (1) The material strip winding equipment and material strip winding system provided by this utility model wind the material strip by setting a material cylinder. The material cylinder includes a flat part and an arc-shaped part. By setting the flat part, the material strip can fit against the flat part and the flat part plays a supporting role for the material strip, thereby keeping the material strip in a straight state. Compared with the cylindrical material cylinder, the alternation of the upper and lower layers of material strip is set on the flat part, which can keep each layer of material strip in a straight state when the axial movement direction of the material cylinder changes, thereby reducing the deformation caused by the change of the axial movement direction of each layer of material strip, reducing the probability of the material strip twisting due to the incomplete overlap between the upper and lower layers of material strip, preventing the occurrence of defects such as edge collapse, and reducing the risk of scrapping the material roll. By setting the flat part, the winding path of the material strip can also be extended, so that a longer material strip can be wound in one rotation of the material cylinder, saving space and winding time of the material strip.

[0020] (2) The tape winding device and tape winding system provided by this utility model, by setting a straight cylinder, enable the tape winding device to be used in conjunction with existing winding machines. The rotating shaft of the winding machine drives the drum to rotate and move in the axial direction. Through the rotation and axial movement of the drum, the tape is spirally wound on the drum. It is convenient to operate and simple to use. The baffle provides a good fixing effect for the tape. After the tape is wound, the baffle is connected to the straight cylinder to prevent the tape from slipping off the sides of the drum and increase the stability of the tape roll.

[0021] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the embodiments described and the accompanying drawings, which are particularly pointed out.

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Example 1

[0029] This utility model provides a material strip winding device for winding material strips.

[0030] This invention does not limit the type of material strip, such as plastic film, metal strip, composite material strip, polymer film, etc.

[0031] like Figure 1 As shown, the material strip winding device of this utility model includes at least one material cylinder 1 and a straight cylinder 2 disposed inside the material cylinder 1. The material cylinder 1 is used to wind the material strip, and the straight cylinder 2 is used to drive the material cylinder 1 to rotate and move the material cylinder 1 in the axial direction.

[0032] In some embodiments, the straight drum 2 is connected to an existing winding machine. The winding machine controls the rotation of the straight drum 2 and moves it axially, thereby causing the material drum 1 to rotate and move axially with the straight drum 2 to wind the material strip. The existing winding machine controlling the rotation and axial movement of the straight drum 2 is prior art and will not be described in detail here.

[0033] In some implementations, such as Figure 1 As shown, the straight cylinder 2 is configured as a cylinder with a cavity, and the outer wall of the straight cylinder 2 is tangent to the outer wall of the material cylinder 1.

[0034] Furthermore, the material cylinder 1 includes a flat portion 11 and an arc-shaped portion 12. The flat portion 11 and the arc-shaped portion 12 are connected to form a closed profile. Multiple layers of material strip are wound on the material cylinder 1. The alternation point between the upper and lower layers of material strip is located on the flat portion 11. The material cylinder 1 changes the direction of axial movement at the alternation point, so that the material strip forms a spiral winding, thereby making each layer of material strip close and tight. The alternation point between the upper and lower layers of material strip is on the flat portion 11, so that each layer of material strip can maintain a straight state when the axial movement of the material cylinder 1 changes, reducing the deformation of each layer of material strip caused by the change of the axial movement direction of the material cylinder 1.

[0035] In some embodiments, the feed cylinder 1 may include two planar portions 11, which are parallel to each other and have the same projection in the vertical direction. The feed cylinder 1 also includes two arc-shaped portions 12, which are symmetrically arranged at both ends of the planar portions 11, and the arc-shaped portions 12 connect the two planar portions 11 to form a closed structure.

[0036] Preferably, the planar portion 11 is symmetrical about the centerline of the arc-shaped portion 12, so that the planar portion 11 and the arc-shaped portion 12 are smoothly connected, and the material strip can fit tightly against the material cylinder 1.

[0037] In some embodiments, the straight cylinder 2 may be disposed between two planar portions 11 and tangent to the planar portions 11.

[0038] For example, the arc-shaped portion 12 can be set as a semi-circle, in which case the diameter of the arc-shaped portion 12 is equal to the diameter of the straight cylinder 2.

[0039] Preferably, the length of the flat portion 11 is greater than or equal to the diameter of the straight cylinder 2, so that the material cylinder 1 can wind a longer strip of material as the straight cylinder 2 rotates once, saving space and time required for the strip winding operation; making the length of the flat portion 11 greater than or equal to the diameter of the straight cylinder 2 can also increase the guiding and bonding effect of the flat portion 11 on the strip of material, reduce the deformation of the strip of material during the winding process, thereby reducing the risk of the strip of material twisting and collapsing.

[0040] like Figure 2As shown, the material strip winding device also includes a baffle 3. After the material strip is wound up, the baffle 3 can be connected to the straight cylinder 2. The baffle 3 is used to fix the material strip and prevent the material strip from slipping off both sides of the cylinder 1.

[0041] For example, the baffle 3 and the straight cylinder 2 can be connected by means of interference fit, tapered connection, protruding line engagement, etc.

[0042] For example, the baffle 3 can be circular, and the diameter of the baffle 3 is greater than or equal to the height of the material cylinder 1 after the material strip is wound. Preferably, the diameter of the baffle 3 is equal to the height of the material cylinder 1 after the material strip is wound, thereby saving space and achieving a good fixing effect.

[0043] As can be seen from the above, compared with the prior art, the material strip winding device of this utility model winds the material strip by setting a material cylinder 1. The material cylinder 1 includes a flat part 11 and an arc-shaped part 12. By setting the flat part 11, the material strip can fit against the flat part 11, thereby keeping the material strip in a straight state. Compared with a cylindrical material cylinder, the alternation point of the upper and lower layers of material strip is set on the flat part 11, which can keep each layer of material strip in a straight state when the axial movement direction of the material cylinder 1 changes. This reduces the deformation caused by the change of the axial movement direction of each layer of material strip, reduces the probability of material strip twisting due to the incomplete overlap between the upper and lower layers of material strip, prevents defects such as edge collapse, and reduces the risk of material roll scrap. By setting the flat part 11, the winding path of the material strip can also be extended, so that a longer material strip can be wound in one rotation of the material cylinder 1, saving space and winding time. By incorporating a straight cylinder 2, the tape winding device can be used in conjunction with an existing winding machine. The existing winding machine controls the rotation and axial movement of the drum 1, causing the tape to spirally wind around it. This design is convenient and simple to use. A baffle 3 effectively secures the tape. After winding, the baffle 3 connects to the straight cylinder 2 to prevent the tape from slipping off the sides of the drum 1, increasing the stability of the roll.

[0045] An exemplary embodiment of this utility model also provides a material strip winding system, including the material strip winding device of Embodiment 1, and may further include an unwinding device, a winding machine, and a guide and correction device, etc.

[0046] The advantages of the material strip winding system over the prior art are the same as those of the material strip winding equipment over the prior art, and will not be repeated here.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
