Description

An adjustable channel width guide platform device Technical Field

[0001] This invention relates to the field of slitting technology for slitting equipment, and more particularly to a guide table device with adjustable channel width. Background Technology

[0002] As a type of slitting and cutting equipment, the slitting unit adopts a fully digital AC variable frequency speed control system, a programmable logic controller (PLC), and full hydraulic control. After slitting the strip material, it is then wound into coils under a certain tension. The shearing speed, individual machine adjustment, and fully automatic operation control are all centralized on the control panel.

[0003] In a slitting mill, the guide table needs to be manually adjusted to guide the strip material into the slitting machine for shearing, depending on the material width. During the shearing process, different strip widths and materials need to be changed according to user requirements, requiring corresponding adjustments to the side guide plates or vertical guide rollers. Furthermore, improper operation and adjustments can sometimes lead to varying degrees of misalignment between the vertical guide rollers or side guide plates, making the strip prone to lateral bending during shearing. Additionally, the use of side guide plates or vertical guide rollers should be selected based on the strip thickness to avoid defects such as lateral bending and edge curling during shearing, thus preventing significant economic losses to the company due to decreased surface quality or disruption of subsequent processes.

[0004] The traditional way to adjust the width of the guide table of a slitting machine is for the operator to adjust the distance between the vertical guide rollers or side guide plates by using a handwheel and a screw. Although this method can roughly meet the required adjustment, it has many drawbacks, such as inconvenience in operation, low operating efficiency, small operating space, low degree of automation, and inability to quantify the adjustment distance. Sometimes, there are also situations where manual adjustment is not possible or the operating space is too small. Furthermore, the current guide structure of the guide table only uses vertical guide rollers or only side guide plates. Side guide plates are suitable for thick materials but are prone to curling when guiding thin materials. Vertical guide rollers can prevent curling of thin materials but are not suitable for thick materials. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide a guide platform device with adjustable channel width.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An adjustable channel width guide table device includes a base, on which a pair of supports are fixed. One end of a lead screw passes through a corresponding lead screw nut and a support in sequence, and is connected to the output shaft of a corresponding motor through a corresponding coupling. The other end of the lead screw passes through another corresponding lead screw nut and a support in sequence and is connected to the shaft of a handwheel. The lead screw nuts are all mounted on corresponding sliders.

[0008] Each slider is equipped with multiple vertical guide rollers, and the arrangement direction of the vertical guide rollers, the extension direction of the rotating shaft located at the center of the vertical guide rollers, and the extension direction of the lead screw in each slider are perpendicular to each other.

[0009] The side guide plate is detachably installed on the inner side of the slider, and when the side guide plate is installed on the slider, the side guide plate covers the cylindrical surface of the vertical guide roller outside the slider; multiple feed plates are also installed on the base through brackets, and the feed plates are parallel to the upper surface of the base.

[0010] As described above, the feed plates are multiple and their arrangement direction is parallel to that of the vertical guide rollers. A feed roller is provided between every two feed plates. The extension direction of the feed roller's shaft is parallel to the extension direction of the lead screw. The height of the top of the feed roller is equal to or higher than that of the feed plate, and the height of the top of the feed roller is lower than that of the top of the vertical guide roller.

[0011] As mentioned above, a guide rod is also provided between the supports. The guide rod is parallel to the lead screw, and both ends of the guide rod pass through the corresponding linear bearings and are fixed to the corresponding supports by bearing nuts. The linear bearings are fixed in the slider.

[0012] As mentioned above, the height of the guide rod and the lead screw are both lower than the height of the feed roller.

[0013] As mentioned above, there are two lead screws, each corresponding to a motor. There are also two guide rods, with each guide rod located outside the corresponding lead screw.

[0014] An encoder is installed on the motor shaft as described above.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention provides a guide table device with adjustable channel width. By setting up a motor, lead screw, lead screw nut, and left and right sliders, it can automatically adjust the distance between the vertical guide rollers or side guide plates to achieve precise adjustment. This invention has a high degree of automation, the adjustment distance can be accurately quantified, the working efficiency is high, and the blade gap adjustment effect is good. The guide structure of this invention integrates both vertical guide rollers and side guide plates, and can achieve the expected adjustment effect for different specifications of strip materials.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] An adjustable channel width guide table device, as shown in Figure 1, includes a base 11, on which a pair of supports 10 are fixed. One end of a lead screw 3 passes sequentially through a corresponding lead screw nut 4 and a support 10, and is connected to the output shaft of a corresponding motor 1 via a corresponding coupling 2. The other end of the lead screw 3 passes sequentially through another corresponding lead screw nut 4 and a support 10, and is connected to the shaft of a handwheel 8. The lead screw nuts 4 are all mounted on corresponding sliders 5, as shown in Figure 3. The area between the sliders 5 is the channel for conveying the conveyor belt in the guide table, and the sliders 5 are parallel to the supports 10. The lead screw 3 and the lead screw nut 4 pass sequentially through another corresponding lead screw nut 4 and a support 10, and are connected to the shaft of a handwheel 8. The screw 4 is a threaded drive that converts rotational motion into linear motion. Compared to the traditional method of manually adjusting the positions of the two sliders 5 separately, the threaded drive between the screw 3 and the screw nut 4 can drive both sliders 5 to move simultaneously along the extension direction of the screw 3. This makes adjusting the distance between the sliders 5 more efficient, and the high precision ensures that the centerline position of the different widths of the strip to be transmitted between the sliders 5 remains constant. This allows the strip to smoothly enter the subsequent equipment of the guide table after changing to different widths of strip. In this embodiment, a motor 1 is used at one end of the screw 3 to control the rotation of the screw 3, further improving the adjustment efficiency.

[0024] The slider 5 is equipped with a guiding structure, which includes a vertical guide roller 14 and a side guide plate 12. The slider 5 is driven by a lead screw 3 and a lead screw nut 4, causing the vertical guide roller 14 and the side guide plate 12 to move linearly along the extension direction of the lead screw 3. Depending on the thickness of the strip, either the vertical guide roller 14 or the side guide plate 12 is selected. The specific configuration of the vertical guide roller 14 and the side guide plate 12 is as follows:

[0025] Each slider 5 is equipped with multiple vertical guide rollers 14. The arrangement direction of the vertical guide rollers 14, the extension direction of the rotating shaft located at the center of the vertical guide roller 14, and the extension direction of the lead screw 3 are all perpendicular to each other. The center line of the material conveying channel is parallel to the arrangement direction of the vertical guide rollers 14. The left and right positions of the material are limited by the cylindrical surface of the vertical guide roller 14 abutting against the edge of the material. When the material is thin, the vertical guide rollers 14 are used to guide it to prevent the material from curling.

[0026] When the strip is thick, the contact area between the side edge of the strip and the corresponding guide structure is relatively large. In this case, the side guide plate 12 is used as the guide structure to improve the adaptability of the guide table. The side guide plate 12 is detachably installed on the inner side of the slider 5. The inner side of the slider 5 is the side of the two sliders 5 facing each other. When the side guide plate 12 is installed on the slider 5, the side guide plate 12 covers the cylindrical surface of the vertical guide roller 14 outside the slider 5, as shown in Figure 2, so that the strip only contacts the side guide plate 12.

[0027] The shaft of the vertical guide roller 14 is mounted on the slider 5 via a pressure cap, and the side guide plate 12 is mounted on the slider 5 via screws.

[0028] The base 11 is also equipped with a feed plate 9 via a bracket, and the feed plate 9 is parallel to the upper surface of the base 11. Furthermore, the feed plate 9 is multi-segmented and its arrangement direction is parallel to the arrangement direction of the vertical guide rollers 14. A feed roller 13 is provided between every two feed plates 9, as shown in Figure 4. The extension direction of the rotating shaft of the feed roller 13 is parallel to the extension direction of the lead screw 3. The height of the top of the feed roller 13 is equal to or higher than that of the feed plate 9, thereby reducing the resistance of the conveyor belt in the horizontal direction. Moreover, the height of the top of the feed roller 13 is lower than that of the top of the vertical guide roller 14, so that the conveyor belt is simultaneously conveyed under the rotation of the cylindrical surfaces of the feed roller 13 and the vertical guide roller 14. The feed plate 9 is used to assist the conveyor belt in passing through. The surface of the feed plate 9 is covered with a PE (polyethylene) plate to prevent scratches on the surface of the conveyor belt. In this embodiment, the PE plate used is white.

[0029] A guide rod 6 is also provided between the supports 10. The guide rod 6 is parallel to the lead screw 3, and the two ends of the guide rod 6 pass through the corresponding linear bearings 7 and are fixed to the corresponding supports 10 by bearing nuts. The linear bearings 7 are fixed in the sliders 5. The guide rod 6 is connected to the left and right sliders 5 through the linear bearings 7 to provide guidance. It is not connected to the drive device and will not rotate with the translation of the material.

[0030] For example, the height of the guide rod 6 and the height of the lead screw 3 are both lower than the height of the feed roller 13, so as to place the strip.

[0031] For example, in this utility model, there are two lead screws 3, each of which corresponds to a motor 1. There are also two guide rods 6, with the two guide rods 6 located on the outer side of the corresponding lead screw 3. The inner side of the lead screw 3 is the area between the two lead screws 3, so that the height of the slider 5 remains consistent throughout the sliding process.

[0032] When the guide table device is running, the strip material is guided from the feed side of the guide table device by the side guide plate 12 and the vertical guide roller 14. To accommodate different strip widths, the motor 1 drives the lead screw 3 to move the slider 5 left and right, thereby significantly adjusting the distance between the sliders 5. When fine adjustment is needed, the handwheel 8 is manually turned. The strip material is fed into the slitting machine for shearing through the material plate 9 and the feed roller 13.

[0033] Furthermore, in order to achieve precise positioning, a rotary encoder is installed on the shaft of the motor 1 in this invention. The encoder used in this embodiment is Pepperl+Fuchs TV150N-09BK0A6TN1024. Different parameters are set according to the width specifications of the strip material, which can more accurately quantify and adjust the distance between the relatively set vertical guide roller 14 and the side guide plate 12.

[0034] It will be apparent to those skilled in the art that the above specific examples are merely preferred embodiments of this utility model. Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
