Description
Technical Field
[0001] This utility model relates to the field of seamless winding machine technology, specifically to a centering positioning device for a seamless winding machine. Background Technology
[0002] A seamless winding machine is a mechanical device used for continuously winding roll materials. It is widely used in the production and processing of roll materials such as metal sheets, plastic films, non-woven fabrics, and paper. Its core function is to evenly and tightly wind continuously produced roll materials into rolls, which facilitates subsequent storage, transportation, and processing. Currently, a centering positioning device for a seamless winding machine is needed.
[0003] However, existing technologies still have the following problems:
[0004] First, the existing seamless winding machine with centering positioning device is not convenient for winding materials of different sizes, and the baffles that block the winding material are not easy to add or remove as needed, so its applicability is generally limited.
[0005] Secondly, existing seamless winding machines using centering positioning devices generally only rely on guide rollers for auxiliary support during winding. However, it is difficult to center and position the material before it passes the guide rollers, which can easily lead to uneven winding and hinders its widespread use.
[0006] To address the aforementioned problems, the inventors propose a centering positioning device for a seamless winding machine. Utility Model Content
[0007] To address the challenges of existing seamless winding machines in conveniently winding materials of different sizes and in providing convenient auxiliary centering and positioning for the wound materials, this invention aims to provide a centering and positioning device for a seamless winding machine.
[0008] To solve the above technical problems, the present invention adopts the following technical solution: a centering positioning device for a seamless winding machine, comprising a base plate, a support plate fixedly connected to the top surface of the base plate, an electric push rod provided on one side surface of the support plate, a winding arc plate provided at one end of the electric push rod, a positioning mechanism provided on the outer side of the winding arc plate, an auxiliary box provided above the base plate, a driving mechanism provided on one side of the auxiliary box, a guide plate provided on one side of the auxiliary box, and a guiding mechanism provided above the guide plate.
[0009] Preferably, the positioning mechanism includes a positioning sleeve that is slidably connected to the outer surface of the winding arc plate, the outer surface of the positioning sleeve is threaded to a top screw, a first positioning baffle is fixedly connected to the outer surface of the positioning sleeve, and a second positioning baffle is provided at the end of the first positioning baffle away from the positioning sleeve.
[0010] Preferably, the guiding mechanism includes a moving plate that is slidably connected to the top surface of the guide plate, an inclined plate that is fixedly connected to one end of the moving plate, and a sleeve block that is fixedly connected to the top surface of the moving plate. The sleeve block is threadedly connected to the outer surface of the threaded rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. By providing a winding arc plate at one end of the electric push rod, the position of the winding arc plate can be adjusted by extending and retracting the electric push rod, thereby adapting to winding materials of different sizes, increasing the versatility and flexibility of the device, and meeting diverse production needs. Furthermore, a positioning mechanism is provided on the outside of the winding arc plate. Adjusting the position of the positioning mechanism allows for winding materials of different widths. The overall length of the positioning baffle can be increased or decreased according to the thickness of the winding material, improving applicability and ensuring the neatness of the winding material.
[0013] 2. By setting up a drive mechanism and a guide mechanism, the material being wound can be assisted in centering and positioning, avoiding uneven winding during the winding process. The material is fed into the auxiliary box through the inclined plate and the moving plate, and then wound. The inclined plate can guide the material to accurately enter the winding position, ensuring the centering and neatness of the winding. Attached Figure Description

[0022] A positioning mechanism 5 is provided on the outer side of the winding arc plate 4. There are four positioning mechanisms 5, with two opposing positioning mechanisms 5 forming a group. The two groups of positioning mechanisms 5 are located at the outer and inner ends of the winding arc plate 4, respectively, thereby blocking the winding material. The positioning mechanism 5 includes a positioning sleeve 51 that is snapped and slidably connected to the outer surface of the winding arc plate 4.

The insert plate 55 at one end of the second positioning baffle 54 is inserted into the insertion groove 56 on the surface of the first positioning baffle 53. The position is limited by the insertion bolts 57, thereby extending the overall length of the positioning baffle assembly. It is suitable for winding materials of different thicknesses.
[0023] An auxiliary box 6 is located above the base plate 1. A guide roller 12 is movably connected to the inner surface of the auxiliary box 6 via bearings. The outer surface of the guide roller 12 is a smooth, polished surface. The guide roller 12 provides support for the hand-rolled material. A drive mechanism 7 is located on one side of the auxiliary box 6. The drive mechanism 7 includes a guide rail box 71. A servo motor 72 is fixedly connected to one end of the guide rail box 71. A threaded rod 73 is located inside the guide rail box 71. One end of the threaded rod 73 is fixedly connected to the output end of the servo motor 72.

A locking block 94 is fixedly connected to the bottom surface of the moving plate 91. A slot matching the structural size of the locking block 94 is opened on the top surface of the guide plate 8. When the threaded rod 73 rotates, the two sets of sleeve blocks 93 and the moving plate 91 move relative to each other or away from each other. The locking block 94 slides in the slot, improving the stability of the movement of the moving plate 91 and the inclined plate 92 combination.
[0024] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as the electric actuator 3, the servo motor 72, and the winding motor 10, should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or a microcontroller, should be selected based on the actual situation to meet the control requirements. The specific connections and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.
[0025] Working principle: When in use, first take out the take-up drum of the material, remove the positioning mechanism 5 at the outer end of the take-up arc plate 4, then put the take-up drum on the outer surface of the take-up arc plate 4, and one end of the take-up drum is attached to the inner end of the positioning mechanism 5. At this time, control the extension of the electric push rod 3 to limit the position of the take-up drum, and then install the removed positioning mechanism 5.
[0026] When installing the positioning mechanism 5, the positioning sleeve 51 is fitted onto the surface of the winding arc plate 4, and the position is limited by the set screw 52. If the thickness of the winding material is greater than that of the first positioning baffle 53, multiple second positioning baffles 54 are combined with the first positioning baffle 53 as needed. The insertion plate 55 at one end of the second positioning baffle 54 is inserted into the insertion groove 56 on the surface of the first positioning baffle 53, and the position is limited by the insertion bolt 57. In this way, multiple second positioning baffles 54 are combined and installed to extend the overall length of the positioning baffle assembly.
[0027] Furthermore, the distance between the two moving plates 91 is adjusted according to the width of the winding drum, and the servo motor 72 is controlled to drive the rotation of the threaded rod 73. At this time, the two sets of insert blocks 93 and the moving plate 91 assembly move relative to or away from each other, and the locking block 94 slides in the slot to improve the stability of the movement of the moving plate 91 and the inclined plate 92 assembly.
[0028] Furthermore, after the adjustment is completed, the winding motor 10 is started, which drives the rotating column 11, electric push rod 3, winding arc plate 4 and winding drum assembly to rotate. The winding material is guided between the two moving plates 91 through the inclined plate 92, and after being supported by the guide clamping roller 12, it is wound on the outer surface of the winding drum. At this time, the winding material can be centered and neatly wound.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
