Description

Technical Field

[0001] This application relates to the field of mechanical adjustment mechanism technology, and in particular to a slitting guide plate lifting device. Background Technology

[0002] In order to improve stability, a guide structure is usually set up when conveying strip materials from the take-up drum to the user end. The guide structure can change the tension of the strip material by changing its own height. However, as the material on the take-up drum decreases, the angle at which the strip material enters the guide structure will also change, and this process will also change the tension. Summary of the Invention

[0003] The purpose of this application is to provide a slitting guide plate lifting device with higher adjustment flexibility.

[0004] To achieve the above objectives, this application provides a slitting guide plate lifting device: including a mounting plate, on which a movable lifter is rotatably connected and a fixed lifter is fixedly connected. A guide plate body is rotatably connected to the upper ends of the movable lifter and the fixed lifter. The guide plate body has a guide groove that runs through the front and rear sides. Both ends of the guide plate body have a first traction shaft and a second traction shaft. The two first traction shafts are coaxial, and the two second traction shafts are coaxial. There are two sets of movable and fixed lifters. The movable end of the movable lifter is rotatably connected to the first traction shaft, and the movable end of the fixed lifter is rotatably connected to the second traction shaft, so that the guide plate body can be flexibly adjusted in angle.

[0005] As a preferred embodiment, there are several guide grooves, which are equidistantly arranged along the length of the guide plate body, allowing multiple strip materials to pass through.

[0006] As a preferred embodiment, the upper and lower edges of both ends of the guide groove are chamfered to reduce scratches and indentations caused by the passage of strip materials.

[0007] As a preferred embodiment, the upper surface of the guide plate body is provided with convection holes communicating with each of the guide grooves, and the lower surface of the guide plate body is also provided with convection holes communicating with each of the guide grooves, so that the strip material can adhere to the inner top wall and inner bottom wall of the guide groove more quickly.

[0008] As a preferred embodiment, both the movable lifter and the fixed lifter are electric telescopic rods. The upper end of the movable lifter is fixedly connected to a first bushing, which is suitable for cooperating with the first traction shaft to form a rotating pair. The upper end of the fixed lifter is fixedly connected to a second bushing, which is suitable for cooperating with the second traction shaft to form a rotating pair, thereby constraining the guide plate body and ensuring stability.

[0009] As a preferred embodiment, a hinge frame is fixedly connected to the upper surface of the mounting plate, and a hinge plate is fixedly connected to the lower end of the movable lifter. The hinge frame is rotatably connected to the hinge plate via a hinge shaft, and the lower end of the fixed lifter is fixedly connected to the upper surface of the mounting plate to ensure the stability of the lifter's position.

[0010] As a preferred embodiment, the distance between the lower ends of the movable lifter and the fixed lifter is greater than the distance between their upper ends. There are two mounting plates, which are symmetrical to each other and are respectively connected to the two types of lifters.

[0011] As a preferred embodiment, each of the mounting plates begins with a positioning groove and a connecting hole, the positioning groove being located in the center of the mounting plate and the connecting hole being located at a corner of the mounting plate, through which bolts pass to secure the mounting plate to the frame.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a fixed and a movable lifting device and rotating it with the two ends of the guide plate body through the bushing, not only is the lifting function taken into account, but the guide plate body also has the angle adjustment function, which can more flexibly adapt to the direction of the introduction and discharge of the strip material and better maintain the tension of the strip material.

[0014] (2) The triangular structure formed by the movable lifter, the guide plate and the mounting plate can maintain the stability of the guide plate itself, so it has good reliability after high-precision adjustment. Attached Figure Description

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and 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. They should not be construed as limiting the specific protection scope of this application.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5 The slitting guide plate lifting device shown includes a mounting plate 1 fixedly connected to the frame. There are two mounting plates 1, which are symmetrical to each other. Each mounting plate 1 has a positioning groove 101 and a connecting hole 102. The positioning groove 101 is located in the center of the mounting plate 1 and is used to provide pre-positioning during installation. The connecting hole 102 is located at the corner of the mounting plate 1 and allows bolts and other connecting parts to pass through to achieve constraint and fixation.

[0026] A movable lifter 3 is rotatably connected to the mounting plate 1, and a fixed lifter 4 is fixedly connected to it. Both the movable lifter 3 and the fixed lifter 4 are electric telescopic rods with good control precision. A hinge frame 103 is fixedly connected to the upper surface of the mounting plate 1. A hinge plate 301 is fixedly connected to the lower end of the sleeve of the movable lifter 3. The hinge frame 103 is rotatably connected to the hinge plate 301 through the hinge shaft 104. Under the premise of restricting the degree of freedom of the lower end of the movable lifter 3, it is ensured that the movable lifter 3 can swing adaptively within a certain range. The lower end of the sleeve of the fixed lifter 4 is directly fixedly connected to the upper surface of the mounting plate 1. The distance between the lower ends of the movable lifter 3 and the fixed lifter 4 is greater than the distance between the upper ends. Since the fixed lifter 4 is vertical, the movable lifter 3 is always tilted, which facilitates the angle adjustment of the guide plate body 2.

[0027] The upper ends of the movable lifting device 3 and the fixed lifting device 4 are rotatably connected to the guide plate body 2, which is the main body that provides guidance for the strip material. Both ends of the guide plate body 2 have a first traction shaft 203 and a second traction shaft 204. The two first traction shafts 203 are coaxial, and the two second traction shafts 204 are coaxial. There are two sets of movable lifting devices 3 and fixed lifting devices 4, which are aligned with the direction of the two mounting plates 1 and are symmetrical about the guide plate body 2. The movable end of the movable lifting device 3 is rotatably connected to the first traction shaft 203. The upper end of the movable lifting device 3 is fixedly connected to the first bushing 302, which cooperates with the first traction shaft 203 to form a rotating pair. The movable end of the fixed lifting device 4 is rotatably connected to the second traction shaft 204. The upper end of the fixed lifting device 4 is fixedly connected to the second bushing 401, which cooperates with the second traction shaft 204 to form a rotating pair. In this way, the guide plate body 2 can not only be adjusted in height but also in angle to adapt to different material feeding needs.

[0028] The guide plate body 2 has guide grooves 201 that run through the front and rear sides for strip materials to pass through. There are several guide grooves 201, which are isolated from each other. These guide grooves 201 are arranged at equal intervals along the length of the guide plate body 2, allowing multiple strip materials to pass through at equal intervals. The upper and lower edges of the front and rear ends of the guide grooves 201 are chamfered, which allows the strip materials to be smoothly introduced or exported, effectively reducing scratches and indentations on the surface of the strip materials. The upper surface of the guide plate body 2 has convection holes 202 that communicate with each guide groove 201, and the lower surface of the guide plate body 2 also has convection holes 202 that communicate with each guide groove 201. Air can quickly flow into or out of the guide grooves 201 through the convection holes 202, so that the strip materials can quickly adhere to the inner top and bottom walls of the guide grooves 201.

[0029] Working principle: When in use, the strip material is pulled out from the feeding cylinder, passes through the guide groove 201 and enters the feeding end. The movable lifter 3 and the fixed lifter 4 lift synchronously to change the height of the guide plate body 2. Only the movable lifter 3 or the fixed lifter 4 lifts to change the tilt angle of the guide plate body 2. Therefore, the lifting device can be flexibly adjusted according to the actual feeding needs, so that the supply of strip material is smoother and more stable.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
