Description

Technical Field

[0001] This utility model relates to the field of film winding equipment, and in particular to a reusable winding cylinder. Background Technology

[0002] With the continuous development of society and economy and the continuous improvement of people's living standards, more and more tools are being manufactured and widely used in agriculture, industry and service industries. Tools come in a wide variety of types, and have been further innovated according to different needs, playing an indispensable role in people's work and life, and providing convenience for their work and life.

[0003] In the production process of a product, packaging operations are usually involved. In the fields of packaging, cable winding, and material winding, the winding drum is the core component that carries and releases the medium. Its structural rationality directly affects the ease of use, material cost, and environmental performance.

[0004] Currently, most spiral wound cylinders on the market are made of paper or plaster, which are difficult to recycle after use, resulting in resource waste and environmental pollution. They are also prone to water absorption and damage, and are easily deformed under pressure during transportation, seriously affecting the normal operation of factories and causing inconvenience to production, which does not meet the needs of the public. Secondly, in order to ensure structural strength, traditional spiral wound cylinders often adopt a solid or thick-walled design, resulting in a large amount of material consumption, which not only increases production costs, but also affects the flexibility of handling and use due to their heavy weight. The excessively heavy structure limits the scope of use.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a reusable winding cylinder. Through the material setting of the winding cylinder body, it can be reused multiple times. Secondly, the design of the weight reduction groove effectively reduces the amount of material used and lowers the production cost while ensuring structural strength.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A recyclable winding cylinder includes a winding cylinder body made of plastic; the winding cylinder body has a through hole that runs vertically through it; at least one first weight-reducing groove is provided on the upper end face of the winding cylinder body along the axial direction; at least one second weight-reducing groove is provided on the lower end face of the winding cylinder body along the axial direction; the first weight-reducing groove and the second weight-reducing groove are arranged alternately along the circumference of the through hole.

[0009] As a preferred option, the main body of the winding cylinder is made of PE material, which has good weather resistance and recyclability, and can be reused multiple times, reducing the consumption of disposable materials and the generation of waste.

[0010] As a preferred embodiment, multiple first weight-reducing grooves are provided, arranged around the periphery of the through hole at intervals, and dispersed circumferentially. Compared to single or few weight-reducing grooves, more redundant material (especially for plastic materials) can be removed within the same structural space, significantly reducing the overall weight of the winding cylinder. Simultaneously, the circumferential distribution avoids material loss due to excessive local grooving, achieving a balance between weight reduction and strength. The uniform spacing of multiple weight-reducing grooves around the periphery of the through hole ensures symmetrical distribution of material allowance in the winding cylinder body along the circumferential direction, avoiding stress concentration caused by excessive or insufficient material in certain areas. When the winding cylinder is subjected to radial loads (such as the tension of the winding medium) or axial forces (such as the pressure of stacked placement), the force can be transmitted through the uniformly distributed material structure, reducing the risk of deformation or breakage.

[0011] As a preferred embodiment, multiple second weight-reducing grooves are provided, arranged around the periphery of the through hole at intervals, and dispersed circumferentially. Compared to single or few weight-reducing grooves, more redundant material (especially for plastic materials) can be removed within the same structural space, significantly reducing the overall weight of the winding cylinder. Simultaneously, the circumferential distribution avoids material loss due to excessive local grooving, achieving a balance between weight reduction and strength. The uniform spacing of multiple weight-reducing grooves around the periphery of the through hole ensures symmetrical distribution of material allowance in the winding cylinder body along the circumferential direction, avoiding stress concentration caused by excessive or insufficient material in certain areas. When the winding cylinder is subjected to radial loads (such as the tension of the winding medium) or axial forces (such as the pressure of stacked placement), the force can be transmitted through the uniformly distributed material structure, reducing the risk of deformation or breakage.

[0012] As a preferred embodiment, both the upper and lower edges of the winding cylinder body are provided with annular chamfers to prevent scratches on the hands.

[0013] As a preferred embodiment, the axial length of the winding cylinder body is 4-6 mm.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the main feature is that the main body of the winding cylinder is made of plastic, which gives it good weather resistance and recyclability, allowing it to be used multiple times, reducing the consumption of disposable materials and the generation of waste.

[0015] Secondly, by setting the first and second weight-reduction grooves on the upper and lower ends of the winding cylinder body respectively, the amount of material used (especially for plastic materials) is effectively reduced while ensuring structural strength, thus reducing production costs.

[0016] Furthermore, the first and second weight-reducing grooves are alternately distributed along the circumference of the through hole, which avoids local weakness in the weight-reducing grooves, makes the stress distribution more uniform, and improves the structural stability of the winding cylinder during the winding or load-bearing process.

[0028] A reusable winding cylinder includes a winding cylinder body 10.

[0029] The main body 10 of the winding drum is made of plastic; preferably, the main body 10 of the winding drum is made of PE material, which has good weather resistance and recyclability, and can be reused multiple times, reducing the consumption of disposable materials and the generation of waste. Preferably, the axial length of the main body 10 of the winding drum is 4-6mm.

[0030] The winding cylinder body 10 has a through hole 11 that runs vertically through it. The upper end face of the winding cylinder body 10 is provided with at least one first weight reduction groove 12 that extends axially in a recessed manner. The lower end face of the winding cylinder body 10 is provided with at least one second weight reduction groove 13 that extends axially in a recessed manner. The first weight reduction groove 12 and the second weight reduction groove 13 are arranged alternately along the circumference of the through hole 11.

[0031] Preferably, multiple first weight-reducing grooves 12 are provided, arranged around the periphery of the through hole 11 at intervals, and dispersed in the circumferential direction. Compared with a single or a small number of weight-reducing grooves, more redundant material (especially for plastic materials) can be removed within the same structural space, significantly reducing the overall weight of the winding cylinder. At the same time, the circumferential distribution avoids material loss caused by excessive local grooving, achieving a balance between weight reduction and strength. The uniform spacing of multiple weight-reducing grooves around the periphery of the through hole 11 ensures that the material allowance of the winding cylinder body 10 is symmetrically distributed in the circumferential direction, avoiding stress concentration caused by excessive or insufficient local material thickness. When the winding cylinder is subjected to radial loads (such as the tension of the winding medium) or axial forces (such as the pressure of stacked placement), the force can be transmitted through the uniformly distributed material structure, reducing the risk of deformation or breakage.

[0032] Preferably, multiple second weight-reducing grooves 13 are provided, arranged around the periphery of the through hole 11 at intervals, and dispersed circumferentially. Compared to single or few weight-reducing grooves, more redundant material (especially for plastic materials) can be removed within the same structural space, significantly reducing the overall weight of the winding cylinder. Simultaneously, the circumferential distribution avoids material loss due to excessive local grooving, achieving a balance between weight reduction and strength. The uniform spacing of multiple weight-reducing grooves around the periphery of the through hole 11 ensures symmetrical distribution of material allowance in the winding cylinder body 10 circumferentially, preventing stress concentration caused by excessively thick or thin local materials. When the winding cylinder is subjected to radial loads (such as the tension of the winding medium) or axial forces (such as the pressure of stacked materials), the force can be transmitted through the uniformly distributed material structure, reducing the risk of deformation or breakage.

[0033] Preferably, the upper and lower edges of the winding cylinder body 10 are provided with annular chamfers 14 to prevent scratches on the hands.

[0034] In practical use, if the film size is large, multiple winding cylinder bodies 10 can be stacked one on top of the other during winding, so that the upper and lower end faces of adjacent winding cylinder bodies 10 abut each other, so that it can meet the winding requirements of films of different sizes. Different numbers of winding cylinder bodies 10 can be stacked according to actual needs, which will not be elaborated here.

[0035] The key design feature of this utility model is that the main body of the winding cylinder is made of plastic, which gives it good weather resistance and recyclability, allowing it to be used multiple times, reducing the consumption of disposable materials and the generation of waste.

[0036] Secondly, by setting the first and second weight-reduction grooves on the upper and lower ends of the winding cylinder body respectively, the amount of material used (especially for plastic materials) is effectively reduced while ensuring structural strength, thus reducing production costs.

[0037] Furthermore, the first and second weight-reducing grooves are alternately distributed along the circumference of the through hole, which avoids local weakness in the weight-reducing grooves, makes the stress distribution more uniform, and improves the structural stability of the winding cylinder during the winding or load-bearing process.

[0038] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
