Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to an automatic lifting device for the slitting machine separation frame. Background Technology

[0002] Slitting machines (also known as slitting machines) are key pieces of equipment in metal sheet processing. They are mainly used to cut wide coils (such as steel plates, aluminum plates, stainless steel plates, etc.) into several narrow coils along their length. They are widely used in automobile manufacturing, home appliance production, building materials, and other fields. Their core function is to achieve high-precision slitting of metal materials to meet the specific width requirements of subsequent processing.

[0003] During the operation of a slitting machine, located at the end of the production line, the narrow strips of material cut into rolls are wound together by take-up rollers. At the same time, in order to ensure the tightness and uniformity of the winding, pressure rollers are used to press the rolls to be wound. As the rolls are continuously wound, the roll diameter increases. In the existing technology, the pressure rollers are manually lifted. However, manual lifting of the pressure rollers is not only difficult to ensure the uniformity of the lifting, but also prone to fatigue and slackness, which can easily lead to uneven winding and operator fatigue. This not only affects the quality of the rolled material winding, but also seriously affects the health of the operators.

[0004] Therefore, an automatic lifting device for the slitting machine's separating frame is urgently needed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic lifting device for the separating frame of a slitting machine, comprising a frame and a take-up roller rotatably connected to the frame, and further comprising a pressing component disposed on the frame for automatically pressing the roll material wound on the take-up roller, and a lifting component for lifting the pressing component.

[0006] The clamping assembly includes a clamping frame disposed on the side of the frame near the take-up roller. The clamping frame is connected to a clamping roller via a rotating shaft. The side wall of the clamping roller is provided with multiple guide plates. The clamping roller is provided with an adjustment assembly for adjusting each guide plate.

[0007] The lifting assembly includes a fixed plate fixedly connected to the top of the frame. Two lifting rods are slidably connected to the fixed plate. One end of each lifting rod is connected to a clamping frame. A lead screw is rotatably connected between the two lifting rods. One end of the lead screw is connected to the clamping frame. A motor is fixedly connected to the side of the fixed plate away from the frame. The output end of the motor is connected to the lead screw through a bevel gear set and a threaded sleeve.

[0008] The adjustment assembly includes an adjustment cavity formed in the pressure roller. The adjustment cavity has a plurality of strip holes arranged in a ring array on the side near each guide plate. An adjustment rod is fixedly connected between the two inner walls of each strip hole. An adjustment plate is slidably connected to each adjustment rod. The end of each adjustment plate away from the rotation axis is connected to the guide plate. The adjustment cavity is provided with a limiting assembly for limiting the position of each adjusted guide plate.

[0009] The limiting assembly includes four fixed rods that are symmetrically arranged in pairs and fixedly connected to the inner wall of the adjustment cavity. The four fixed rods are slidably connected to an arc-shaped plate. Each of the axially arranged adjustment plates has a limiting plate fixedly connected to one end away from the guide plate. Each limiting plate is arranged opposite to the arc-shaped plate.

[0010] The limiting components are arranged in a ring array in the adjustment cavity, and the adjustment cavity is provided with a driving component for driving each set of limiting components. The driving component includes two mutually symmetrically arranged driving plates that are slidably connected to the inner wall of the adjustment cavity. Multiple rotating plates are respectively hinged to the opposite side of the two driving plates. The end of each rotating plate away from the driving plate is hinged to each arc plate. The adjustment cavity is provided with a moving component for moving the two driving plates.

[0011] The movable component includes a movable rod rotatably connected between two opposing inner walls of the adjustment cavity. The movable rod has two threaded strips with oppositely oriented threads on its side wall. The two threaded strips are respectively threaded to movable plates. One end of each movable plate is connected to a rotating plate. One end of the movable rod passes through a pressure roller and is fixedly connected to a turntable.

[0012] A connecting rod is fixedly connected between the two inner walls of the adjustment cavity. The connecting rod and the moving rod are symmetrically arranged. A connecting plate is slidably connected to the side wall of the connecting rod. One end of each of the two connecting plates is connected to two rotating plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model's automatic lifting device for the slitting machine's separating frame, through the setting of the clamping component, ensures the tightness and neatness of the roll winding. Simultaneously, by utilizing the lifting component, it can automatically calculate the lifting interval based on the original roll diameter, winding speed, and roll thickness, thereby strictly controlling the lifting distance of the clamping roller. This ensures proper contact between the clamping roller and the roll, ultimately guaranteeing neat winding. This reduces the risk of uneven winding or damage to the roll edges due to human error, thus improving the winding quality of the roll while reducing workload.

[0015] The automatic lifting device for the slitting machine separation frame of this utility model, through the setting of the adjustment components and the cooperation of the limiting components, realizes the adjustment of the spacing between each guide plate, so as to adapt to the winding and guiding of rolls of different widths, thereby improving the flexibility of the pressing components during use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1-4 The automatic lifting device for the slitting machine separating frame shown in the figure includes a frame 101 and a take-up roller 102 rotatably connected to the frame 101. It also includes a pressing component disposed on the frame 101 for automatically pressing the roll material wound on the take-up roller 102 and a lifting component for lifting the pressing component.

[0023] The clamping assembly includes a clamping frame 201 disposed on the side of the frame 101 near the take-up roller 102. The clamping frame 201 is connected to a clamping roller 203 via a rotating shaft 202. The side wall of the clamping roller 203 is provided with multiple guide plates 204. The clamping roller 203 is provided with an adjustment assembly for adjusting each guide plate 204.

[0024] It should be noted here that the clamping components facilitate the clamping of the wound material, ensuring the tightness and neatness of the wound material.

[0025] Please see Figure 1 The lifting assembly shown in the figure includes a fixed plate 301 fixedly connected to the top of the frame 101. Two lifting rods 302 are slidably connected to the fixed plate 301. One end of the two lifting rods 302 is connected to the clamping frame 201. A lead screw 303 is rotatably connected between the two lifting rods 302. One end of the lead screw 303 is connected to the clamping frame 201. A motor 304 is fixedly connected to the side of the fixed plate 301 away from the frame 101. The output end of the motor 304 is connected to the lead screw 303 through a bevel gear set and a threaded sleeve.

[0026] It should be noted that by setting the lifting component, the lifting interval can be automatically calculated based on the original roll diameter, winding speed and roll thickness, thereby strictly controlling the lifting distance of the pressure roller 203, ensuring proper contact between the pressure roller 203 and the roll, and ultimately ensuring neat winding. This reduces the risk of uneven winding or damage to the roll edge due to human error, thus improving the winding quality of the roll while reducing the workload.

[0027] It is worth noting that the connection between the motor 304 and the lead screw 303 is as follows: a bevel gear is fixedly connected to the output end of the motor 304, a threaded sleeve is threadedly connected to the side wall of the lead screw 303, and one end of the threaded sleeve is rotatably connected to the fixed plate 301. A bevel gear is also fixedly connected to the side wall of the threaded sleeve, and the two bevel gears are meshed with each other.

[0028] Working principle: When winding up the cut roll material, firstly, one end of multiple parallel roll materials is fixedly connected to the winding roller 102. Then, the rotation of the winding roller 102 is used to wind up the roll material. During the winding process, the lifting component moves the pressing frame 201, causing the pressing roller 203 to move closer to the winding roller 102. (In the early stage of winding, since the winding diameter of the roll material is small, no pressing is required. However, as the winding diameter of the roll material gradually increases, the guiding and dividing action of each guide plate 204 will separate the winding of multiple roll materials. At the same time, the pressing roller 203 will abut against the side wall of the roll material, thereby achieving winding and pressing of the roll material.)

[0029] During the continuous winding process of the roll material, the motor 304, under the control of the controller, will automatically calculate the lifting interval based on the original roll diameter, winding speed and roll thickness, thereby strictly controlling the lifting distance of the pressure roller 203, ensuring proper contact between the pressure roller 203 and the roll material, and ultimately ensuring neat winding. This reduces the risk of uneven winding or damage to the roll material edges caused by human error, thereby reducing the workload while improving the winding quality of the roll material. Example 2

[0030] Please see Figure 2 and Figure 3 This embodiment further illustrates Example 1. The adjustment assembly shown in the figure includes an adjustment cavity 404 opened in the pressure roller 203. The adjustment cavity 404 has a plurality of strip holes 401 arranged in a ring array on the side near each guide plate 204. An adjustment rod 402 is fixedly connected between the two inner walls of each strip hole 401. An adjustment plate 403 is slidably connected to each adjustment rod 402. One end of each adjustment plate 403 away from the rotation shaft 202 is connected to the guide plate 204. The adjustment cavity 404 is provided with a limiting assembly for limiting the guide plate 204 after each adjustment is completed.

[0031] It should be noted here that by adjusting the settings of the components, and with the cooperation of the limiting components, the spacing between each guide plate 204 can be adjusted, making it adaptable to the winding and guiding of rolls of different widths, thereby improving the flexibility of the clamping components during use.

[0032] Please see Figure 3 and Figure 4 The limiting component shown in the figure includes four fixed rods 501 that are fixedly connected to the inner wall of the adjusting cavity 404 and arranged symmetrically in pairs. The four fixed rods 501 are slidably connected to an arc plate 502. Each adjusting plate 403 arranged axially is fixedly connected to a limiting plate 503 at one end away from the guide plate 204. Each limiting plate 503 is arranged opposite to the arc plate 502.

[0033] It should be noted here that the limiting component is used to tighten and limit the guide plate 204 after adjustment, thereby ensuring the stability of the guide plate 204 during use.

[0034] Please see Figure 3 and Figure 4The limiting components shown in the figure are arranged in a ring array in the adjustment cavity 404. The adjustment cavity 404 is provided with a driving component for driving each set of limiting components. The driving component includes two driving plates 601 that are slidably connected to the inner wall of the adjustment cavity 404. Multiple rotating plates 602 are respectively hinged to the opposite side of the two driving plates 601. The end of each rotating plate 602 away from the driving plate 601 is hinged to each arc plate 502. The adjustment cavity 404 is provided with a moving component for moving the two driving plates 601.

[0035] It should be noted here that the drive components are configured to move the various curved plates 502 closer to or further apart from each other.

[0036] Please see Figure 3 and Figure 4 The movable component shown in the figure includes a movable rod 701 rotatably connected between two inner walls of the adjustment cavity 404. The movable rod 701 has two threaded strips with opposite directions of thread on its side wall. The two threaded strips are threaded to movable plates 702 respectively. One end of the two movable plates 702 is connected to two rotating plates 602 respectively. One end of the movable rod 701 passes through the pressure roller 203 and is fixedly connected to a turntable. A connecting rod 703 is fixedly connected between the two inner walls of the adjustment cavity 404. The connecting rod 703 is symmetrically arranged with the movable rod 701. The side wall of the connecting rod 703 is slidably connected to a connecting plate 704. One end of the two connecting plates 704 is connected to the two rotating plates 602 respectively.

[0037] It should be noted here that the movable component allows the two drive boards 601 to move closer to or further apart from each other.

[0038] Working principle: When adjusting the spacing between adjacent guide plates 204, first rotate the turntable to drive the moving rod 701 to rotate. During the rotation of the moving rod 701, the two driving plates 601 are driven to move away from each other by the threaded strips with opposite directions on the side wall of the moving rod 701 and the threaded transmission of the two driving plates 601, as well as the guiding action of the connecting rod 703 and the connecting plate 704. Then, by the mutual approaching rotation of each rotating plate 602, each arc plate 502 is driven to separate from the limiting plate 503.

[0039] After the arc plate 502 separates from the limiting plate 503, the guide plates 204 can be adjusted and moved. After the spacing between the guide plates 204 is adjusted and moved, the turntable rotates in the opposite direction. Then, under the transmission action of the threaded strips with opposite directions on the side wall of the moving rod 701 and the threads of the two drive plates 601, as well as the guiding action of the connecting rod 703 and the connecting plate 704, the two opposing drive plates 601 are driven to move closer to each other. Then, by using the mutual rotation of the rotating plates 602, the arc plates 502 are pushed to abut against the limiting plate 503. Under the pressing action of the arc plates 502, the limiting and pressing of the guide plates 204 is achieved. This realizes the adjustment of the spacing between the guide plates 204, making it adaptable to the winding and guiding of rolls of different widths, thereby improving the flexibility of the pressing assembly in use.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
