Description

Technical Field

[0001] The utility model relates to the technical field of winding and unwinding devices, in particular to an adjustable material-blocking winding and unwinding device. Background Art

[0002] In the field of high-speed printing machines, production preparation time is further compressed to improve printing production efficiency. The reeling and unwinding operations are mainly performed manually, and the preparation time is relatively long. Therefore, the higher the degree of automation of the reeling and unwinding device, the shorter the corresponding preparation time. With the development of automated production, more and more manual reeling and unwinding are being replaced by air-top reeling and unwinding, that is, the installation and positioning of the material roll is achieved by the cylinder cone top on one side and the manual cone top or cylinder cone top on the other side.

[0003] Air-cap rewinding and unwinding has greatly improved production efficiency. However, it was found during use that for some larger diameter rolls, slippage is prone to occur when the tension is low, resulting in uneven edges of the material and affecting the production and processing of subsequent processes. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and propose an adjustable material blocking and unwinding device, which can assist in limiting the edge positions on both sides of the material roll, thereby effectively alleviating the occurrence of the roll slip phenomenon and reducing secondary rework.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A material-blocking reeling and winding device with adjustable speed comprises a supporting shaft and a left swivel arm and a right swivel arm fixedly mounted at both ends of the supporting shaft, wherein first top cone mechanisms are symmetrically mounted at both ends of the left swivel arm, and second top cone mechanisms are symmetrically mounted at both ends of the right swivel arm on the same axis as the two first top cone mechanisms, a material-blocking space is formed between the first and second top cone mechanisms which are arranged opposite to each other, a material-blocking mechanism is symmetrically mounted on the center of the outer peripheral surface of the supporting shaft, and the material-blocking mechanism comprises a material-blocking assembly which is adjustably and symmetrically mounted on both sides of the material-blocking space.

[0007] Furthermore, a linear slide rail arranged along the length direction is symmetrically fixed on the outer circumferential surface of the support shaft, a slider is slidably provided on the linear slide rail, and the material blocking assembly is fixedly mounted on the slider and a locking mechanism is connected between the linear slide rail.

[0008] Furthermore, the material stopping assembly includes a material stopping shaft arranged perpendicular to the supporting shaft, a mounting seat is fixedly connected between one end of the material stopping shaft and the corresponding sliding block, the mounting seat is integrally formed with the material stopping shaft, and the other end extends at least to the side of the axis of the relatively arranged first top cone mechanism and the second top cone mechanism away from the supporting shaft.

[0009] Furthermore, a material stopping cylinder is coaxially sleeved outside the material stopping shaft, and rotating bearings are fixedly installed between the two ends of the inner wall of the material stopping cylinder and the material stopping shaft.

[0010] Furthermore, a spacer sleeve sleeved on the material stopping shaft is provided between the material stopping cylinder and the mounting seat.

[0011] Furthermore, the locking mechanism includes a slide plate fixedly mounted on the side of the slider away from the linear slide rail, one end of the slide plate extends to the outside of the slider and is provided with a screw hole, a locking screw is provided in the screw hole, and the lower end of the locking screw abuts against the slide rail.

[0012] Furthermore, the first cone ejection mechanism is a cylinder cone ejection mechanism, and the second cone ejection mechanism is a manual cone ejection mechanism.

[0015] (2) The utility model realizes the sliding connection between the material blocking assembly and the support shaft through the structure of a linear slide rail and a slider, and then locks and positions them through a locking mechanism, which is convenient for quick adjustment and easy to use.

[0016] (3) The utility model forms a shaft with a seat by providing an integrally formed material-blocking shaft and a mounting seat, which facilitates the assembly of the slider and the material-blocking shaft. At the same time, the other end of the material-blocking shaft extends to the outside of the material-pushing axis, ensuring that all materials are within the limited range of the material-blocking shaft, thereby improving the material-blocking effect.

[0033] (Example 1)

[0034] like Figures 1 to 4 The adjustable material blocking reeling and unwinding device shown comprises a support shaft 1, a left rotating arm 2, a right rotating arm 3, a first top cone mechanism 4, a second top cone mechanism 5 and a material blocking mechanism, wherein the left rotating arm 2 and the right rotating arm 3 are fixedly mounted on the left and right ends of the support shaft 1, respectively; the first top cone mechanism 4 is provided with two groups and is symmetrically mounted on the upper and lower ends of the left rotating arm 2; the first top cone mechanism 4 is also provided with two groups and is symmetrically mounted on the upper and lower ends of the right rotating arm 3; the first top cone mechanism 4 and the second top cone mechanism 5 located at the upper end and the first top cone mechanism 4 and the second top cone mechanism 5 located at the lower end are respectively coaxially arranged opposite to each other, thereby forming two material blocking spaces. The material blocking mechanism is provided with two groups and is symmetrically arranged on the front and rear sides of the outer peripheral surface of the support shaft along the center. Each material blocking mechanism comprises a material blocking assembly 6 which is adjustably and symmetrically mounted on both sides of the material blocking space, thereby assisting in limiting the edge positions on both sides of the material roll, thereby effectively alleviating the occurrence of the slipping phenomenon and reducing secondary rework. The material blocking component 6 can be adjusted to fit the side of the material roll according to the width of the material roll, thereby meeting the positioning requirements of material rolls of different widths and having a wide range of applications.

[0035] Since the cylinder cone top has high requirements for the swivel arm, in order to simplify the structure of the swivel arm, the first cone top mechanism 4 of this embodiment adopts a cylinder cone top, and the second cone top mechanism 5 is a manual cone top, which has lower manufacturing and installation costs and is easy to produce and maintain.

[0036] The outer peripheral surface of the support shaft 1 is symmetrically fixed with linear slide rails 7 arranged along the length direction, and each linear slide rail 7 is slidably provided with a slider 8. The material blocking assembly 6 is fixedly installed on the slider 8 and a locking mechanism 9 is connected between the linear slide rail 7, thereby realizing a sliding connection between the material blocking assembly 6 and the support shaft 1, and then locked and positioned through the locking mechanism 9, which is convenient for quick adjustment and easy to use.

[0037] Specifically, the material blocking assembly 6 includes a material blocking shaft 6-1 arranged perpendicular to the support shaft 1, a mounting seat 6-2 is fixedly connected between one end of the material blocking shaft 6-1 and the corresponding slider 8, and the mounting seat 6-2 is integrally formed with the material blocking shaft 6-1, thereby forming a seated shaft, which is convenient for assembling the slider 8 and the material blocking shaft 6-1. The other end of the material blocking shaft 6-1 extends to the side of the axis of the first top cone mechanism 4 and the second top cone mechanism 5 arranged oppositely away from the support shaft 1, ensuring that all materials are within the limited range of the material blocking shaft 6-1, thereby improving the material blocking effect. The material blocking shaft 6-1 is coaxially sleeved with a material blocking barrel 6-3, and a rotating bearing 6-4 is fixedly installed between the inner wall ends of the material blocking barrel 6-3 and the material blocking shaft 6-1, thereby realizing the rotational connection between the material blocking barrel 6-3 and the material blocking shaft 6-1. When the material roll is retracted and released, the rotating material blocking barrel 6-3 can not only play the role of blocking the material, but also effectively reduce friction and avoid wear on the side of the material roll. A spacer sleeve 6-5 is provided between the material blocking cylinder 6-3 and the mounting seat 6-2, which is sleeved on the material blocking shaft 6-1 to prevent the rotating bearing 6-4 from direct contact with the mounting seat 6-2, protect the rotating bearing 6-4 from damage, and reserve more installation space for fixing the rotating bearing 6-4.

[0038] The locking mechanism 9 includes a slide plate 9-1 fixedly mounted on the side of the slider 8 away from the linear slide rail 7. One end of the slide plate extends to the outside of the slider 8 and is provided with a screw hole. A locking screw 9-2 is provided in the screw hole. The lower end of the locking screw 9-2 abuts against the slide rail 7. By rotating the locking screw 9-2, when the lower end of the locking screw 9-2 abuts against the slide rail 7, the slider 8 is fixed. When the locking screw 9-2 is rotated in the opposite direction to separate its lower end from the slide rail 7, the slider 8 can be easily slid to adjust the position of the material blocking assembly 6 to meet the material blocking requirements of rolls of different widths.

[0039] In this embodiment, a material blocking assembly 6 is arranged on both sides of the top material space to assist in limiting the edge positions of both sides of the material roll, thereby effectively alleviating the occurrence of slippage and reducing secondary rework; the material blocking assembly 6 is adjustable and can be adjusted to fit the side of the material roll according to the width of the material roll, thereby meeting the limiting requirements of material rolls of different widths and having a wide range of applications.

[0040] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
