Abstract

The present invention provides a guiding method for the synchronous lifting of pressure rollers, the core of which is to first arrange a first lifting member and a second lifting member at intervals on a frame, so that the first lifting member is fixed relative to the frame, and the second lifting member can be hinged and rotated relative to the frame; and the pressure rollers are horizontally arranged at intervals on the pressure roller frame, and then the two ends of the pressure roller frame are hinged to the first lifting member and the second lifting member respectively. When the pressure roller frame drives the pressure roller to rise and fall, the pressure roller frame and the second lifting member are hinged and rotated to prevent the first lifting member and the second lifting member from being stuck, thereby realizing the synchronous lifting and lowering of the pressure rollers, and when descending, the pressure rollers and the supporting rollers clamp the plate strip for transmission, thereby realizing rapid adaptation and clamping of different plate thicknesses, saving the time of manually adjusting the position of the pressure rollers due to changes in plate thickness, and improving the clamping efficiency of the plate strip.

Description

Technical Field

[0001] The invention relates to the field of metal surface treatment, and in particular to a guiding method for a pressure roller. Background Art

[0002] During the grinding process, in order to ensure that the plates can move horizontally, rollers and pressure rollers are often used to clamp the plates up and down. However, there are different batches of plates, that is, different plate thicknesses. In order to ensure that they can adapt to various thicknesses, the initial idea is to arrange the rollers uniformly under the plates, and raise and lower the pressure rollers uniformly. The pressure rollers are arranged on the roller frame for rotation, and the two ends of the roller frame are suspended and raised and lowered uniformly. In order to ensure efficiency, the two ends of the roller frame are respectively driven by cylinders for extension and retraction. However, during the test, it was found that the movements of the two sides could not be synchronized, and the lifting and lowering often occurred unsmoothly during work.

[0003] The main reason for the asynchronous lifting action is due to objective factors such as processing errors and assembly errors, which make the lifting cylinders on both sides always produce a small and irresistible lifting height difference when lifting, which easily leads to the asynchronous movement of the piston rods of the two lifting cylinders. In severe cases, the lifting cylinder piston rods may be twisted and the piston cylinder may crack, which not only affects the service life of the synchronous lifting mechanism, but also easily poses a threat to personal safety.

[0004] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research. The technical solution to be introduced below is produced in this context. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a guiding method for a pressure roller: first, a first lifting member and a second lifting member are arranged at intervals on the frame, so that the first lifting member is fixed relative to the frame, and the second lifting member can be hinged and rotated relative to the frame; and the pressure roller is arranged horizontally at intervals on the pressure roller frame, and then the two ends of the pressure roller frame are hinged to the first lifting member and the second lifting member respectively. When the pressure roller frame drives the pressure roller to rise and fall, the pressure roller frame and the second lifting member are hinged and rotated to prevent the first lifting member and the second lifting member from getting stuck, thereby realizing synchronous lifting and lowering of the pressure roller.

[0006] The technical solution of the present invention is achieved as follows:

[0007] A method for guiding a pressure roller comprises the following steps:

[0008] S1: Pre-installed rack; the rack is configured as a supporting member;

[0009] S2: Pre-installed pressure roller; the pressure roller is a rotating part;

[0010] S3: Pre-installed lifting module; the first lifting module includes a first beam fixedly mounted on the frame, a first lifting member fixedly connected below the first beam, and the first lifting member is configured to be lifted and lowered in an upward and downward direction by its own telescopic manner;

[0011] S4: pre-installed pressure roller frame; the pressure roller frame is configured as a mounting support for the pressure roller, and at least two pressure rollers are horizontally spaced and mounted on the pressure roller frame;

[0012] S5: Pre-installing a lifting guide module; the lifting guide module includes a second crossbeam fixedly mounted on the frame, a second lifting member hingedly connected below the second crossbeam, such that the second lifting member can rotate left and right relative to the second crossbeam; the second lifting member is configured to be lifted and lowered in the vertical direction by self-extension;

[0013] S6: Install the pressure roller frame; hinge the lower ends of the first lifting member and the second lifting member to the left and right ends of the pressure roller frame respectively, so that the pressure rollers on the pressure roller frame are on the same horizontal line;

[0014] S7: The pressure roller is raised and lowered and guided; the lifting and lowering of the pressure roller frame is controlled by the first lifting member and the second lifting member. During the lifting process, the hinged structure of the second lifting member and the second crossbeam causes the right end of the pressure roller frame to swing slightly in the left and right directions when it is lifted and lowered, thereby preventing the left and right ends of the first lifting member and the second lifting member from getting stuck during the lifting process, thereby realizing the synchronous lifting and lowering of the left and right ends of the pressure roller frame.

[0015] Preferably, a lower crossbeam is fixedly connected below the first lifting member, and the left end of the pressure roller frame is hinged to the front and rear sides of the lower crossbeam, so that the first lifting member can control the lifting of the left end of the pressure roller frame.

[0016] Preferably, the first crossbeam is further provided with a guide rod which is symmetrical along the front-to-back direction and fixedly connected to the lower crossbeam. In step S7, when the first lifting member is lifted or lowered, the guide rod only slides up and down relative to the first crossbeam, and after the first lifting member and the second lifting member are lifted or lowered into place, the pressure roller frame is restricted from swinging significantly in the left and right directions, thereby playing a guiding and limiting role for the lifting module.

[0017] Preferably, the first crossbeam is also provided with a first adjusting member which is symmetrical along the front-to-back direction and fixedly connected to the lower crossbeam. The first adjusting member includes a first screw and a first adjusting nut screwed together at both ends of the first screw. The upper end of the first screw passes through the interior of the first crossbeam. When the first lifting member is lifted or lowered, the first screw and the lower crossbeam are lifted or lowered synchronously; the first adjusting nut at the upper end of the first screw limits it from falling off the first crossbeam when sliding downward; after the first lifting member and the second lifting member are lifted or lowered into place, the first screw limits the pressure roller frame from swinging in the left and right directions, thereby playing an auxiliary guiding and limiting role for the lifting module.

[0018] Preferably, the front and rear sides of the lower crossbeam are provided with horizontal plates fixedly connected to the lower crossbeam, and the horizontal plates are provided with avoidance holes, the width of the avoidance holes is greater than the diameter of the first screw, and the lower end of the first screw passes through the avoidance holes and is locked to the lower crossbeam by the first adjusting nut; after the first lifting member and the second lifting member are lifted into place, the horizontality and the lowering distance of the left end of the pressure roller frame can be adjusted by rotating the position of the first adjusting nut on the first screw to adjust the horizontality of the pressure roller.

[0019] Preferably, a second adjusting member symmetrically arranged along the front-to-back direction is hingedly provided under the second crossbeam. In step S7, when the pressure roller frame is raised or lowered, the second adjusting member can be rotated in the left-right direction relative to the second crossbeam, thereby achieving auxiliary guiding effect on the pressure roller frame.

[0020] Preferably, a horizontal ear plate is provided at the right end of the pressure roller frame, and a slot hole is provided on the horizontal ear plate; the second adjusting member includes a second screw and a second adjusting nut; the width of the slot hole is greater than the diameter of the second screw, and the lower end of the second screw passes through the slot hole on the pressure roller frame and is locked to the pressure roller frame by the second adjusting nut. After the first lifting member and the second lifting member are lifted into place, the horizontality and the lowering distance of the right end of the pressure roller frame can be adjusted by rotating the second adjusting nut at the position of the lower end of the second screw to adjust the horizontality of the pressure roller.

[0021] Preferably, the pressure rollers are arranged on the pressure roller frame in the left-right direction, and the axes of the pressure rollers extend in the front-back direction.

[0022] Preferably, a right hinge is fixedly connected to the right end of the pressure roller frame, and the right hinge is located in the middle position of the front and rear directions of the pressure roller frame. The right hinge and the front and rear sides of the lower cross beam form three hinge points on the pressure roller frame, thereby forming an isosceles triangle suspension structure on the pressure roller frame, so that the pressure roller frame can be stably suspended and thus smoothly lifted and lowered.

[0023] Preferably, the hinge positions between the left end of the roller frame and the front and rear sides of the lower cross beam are located outside the roller frame, providing sufficient space for the installation of the hinged part at the left end of the roller frame.

[0024] The principles and beneficial effects of the present invention using the above technical solution are:

[0025] The present invention provides a guiding method for pressure rollers, which first arranges a plurality of horizontally spaced roller groups on a frame and places the plate strip on the rollers; then arranges the pressure rollers horizontally at intervals on the roller frame to align the pressure rollers with the rollers; then hinges the lifting unit to both ends of the roller frame, and controls the distance between the pressure rollers and the rollers by controlling the lifting of the roller frame; when the thickness of the plate strip changes, the pressure rollers are driven to rise and fall by the lifting of the roller frame, and the pressure rollers and the rollers clamp the plate strip for transmission, thereby realizing rapid adaptation and clamping of different plate thicknesses, saving time for manually adjusting the position of the pressure rollers due to changes in plate thickness, and improving the clamping efficiency of the plate strip.

DETAILED DESCRIPTION

[0039] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] In the description of the present invention, the term "at least one" refers to one or more than one, unless otherwise clearly defined. The terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] The specific implementation of the present invention is as follows: Figure 1-11 As shown, this embodiment provides a method for guiding a pressure roller, comprising:

[0043] S1: Pre-installing a rack 1; the rack 1 is configured as a support member; the rack 1 includes a set of bottom cross beams 101 spaced apart in the front-to-back direction, and at least one set of longitudinal beams 102 spaced apart in the left-to-right direction are provided on the bottom cross beams 101; the cross beams 101 and the longitudinal beams 102 are connected together by screws or welding to ensure the structural strength of the rack 1 as a support member;

[0044] S2: Pre-setting a pressure roller 8; the pressure roller 8 is a rotating part, for example, the pressure roller 8 can be a cylinder;

[0045] S3: Pre-installed lifting module; the first lifting module includes a first crossbeam 2 fixedly mounted on the frame 1, and a first lifting member 3 is fixedly connected below the first crossbeam 2. Specifically, the first crossbeam 2 is fixedly mounted between each group of longitudinal beams 102 along the left and right directions; a first lifting member 3 is fixedly connected below the first crossbeam 2, and the first lifting member 3 is configured to be lifted and lowered in the up and down directions by its own telescopic manner. For example, the first lifting member 3 can be configured as a cylinder to provide power for lifting and lowering the left end of the pressure roller frame 6.

[0046] like Figure 1-5 As shown, a lower cross beam 7 is fixedly connected to the bottom of the first lifting member 3, and the lower cross beam 7 is the carrier for the hinged connection between the pressure roller frame 6 and the first lifting member 3, and the connection between the two is specifically achieved in the following way: the first lifting member 3 includes a retractable first lifting rod 301, and the first lifting rod 301 is locked and connected to the pull rod 22 through a hexagonal nut 302 below the first lifting rod 301; a fixing pin 21 perpendicular to the length direction of the pull rod 22 is fixedly connected to the outer wall of the lower end of the pull rod 22, and an avoidance notch is provided on the lower cross beam 7. The fixing pin 21 passes through the avoidance notch on the pull rod 22 and the lower cross beam 7 to connect the pull rod 22 and the lower cross beam 7 together. In order to prevent the fixing pin 21 from moving in the axial direction, a cover plate 14 is threadedly connected to the avoidance notch on the lower cross beam 7 to prevent the fixing pin 21 from axially escaping from the lower cross beam 7.

[0047] like Figure 3-5 As shown, the first crossbeam 2 is provided with a guide rod 23 symmetrically fixed to the lower crossbeam 7 along the front-to-back direction. A fixing pin 21 perpendicular to the length direction of the guide rod 23 is fixedly connected to the outer wall of the lower end of the guide rod 23. The fixing pin 21 passes through the guide rod 23 and the interior of the lower crossbeam 7 to connect the guide rod 23 and the lower crossbeam 7 together. Similarly, in order to prevent the fixing pin 21 from moving in the axial direction, a cover plate 14 is threadedly connected to the avoidance notch on the lower crossbeam 7 to prevent the fixing pin 21 from axially falling out of the lower crossbeam 7.

[0048] The guide rod 23 passes through the first crossbeam 2; when the first lifting member 3 drives the lower crossbeam 7 to rise and fall, the guide rod 23 only slides up and down relative to the first crossbeam 2. Through the extrusion limit between the guide rod 23 and the first crossbeam 2, the pressure roller frame 6 is limited from swinging in the front and rear directions, thereby playing a guiding and limiting role for the first lifting unit.

[0049] like Figure 3-5As shown, the first crossbeam 2 is further provided with a first adjustment device symmetrically along the front-to-back direction and fixed to the lower crossbeam 7. Specifically, the first adjustment member includes a first screw 5 and a first adjustment nut 16 screwed on both ends of the first screw 5. The front and rear sides of the lower crossbeam 7 are fixedly connected to a horizontal plate 31 with an avoidance hole. The width of the avoidance hole is greater than the diameter of the first adjustment screw 5 to ensure that the first adjustment screw 5 has sufficient installation space in the slot; the lower end of the first adjustment screw 5 passes through the avoidance hole and passes through the two first adjustment nuts 16 located above and below the horizontal plate 31. Locked on the lower crossbeam 7; when the first lifting member 3 stops lifting, by rotating the first adjusting nut 16 at the position of the lower end of the first adjusting screw 5, the first adjusting nut 16 squeezes the lower crossbeam 7, and transmits the squeezing force to the pressure roller frame 6, so that the pressure roller frame 6 remains horizontal after being in place, and the horizontality of the left end of the pressure roller frame 6 can be adjusted; thus, the pressure roller 8 remains horizontal, and after adjustment, the first adjusting screw 5 is locked on the lower crossbeam 7 again by the two first adjusting nuts 16, so that the first adjusting screw 5 and the left end of the pressure roller frame 6 remain relatively fixed in the vertical direction;

[0050] The upper end of the first screw 5 passes through the inside of the first crossbeam 2. When the first lifting member 3 is lifted or lowered, the first screw 5 and the lower crossbeam 7 are lifted or lowered synchronously. In order to prevent the first screw 5 from falling off the lower crossbeam 7 when moving downward, a first adjusting nut 16 is also screwed on the upper end of the first screw 5. After the first lifting member 3 and the second lifting member 17 are lifted or lowered into place, the extrusion limit between the first screw 5 and the first crossbeam 2 is used to limit the pressure roller frame 6 from swinging in the left and right directions, thereby playing an auxiliary guiding and limiting role for the lifting module.

[0051] S4: Pre-installing a pressure roller frame 6; the pressure roller frame 6 is configured as a mounting support for the pressure rollers 8, with at least two pressure rollers 8 horizontally spaced apart and mounted on the pressure roller frame 6; specifically, the pressure roller frame 6 includes two vertical plates 605 arranged in the front-to-back direction, each of the vertical plates 605 having mounting holes 608 for mounting the pressure rollers 8; a receiving area 612 is formed between the vertical plates 605 in the front-to-back direction, and the pressure rollers 8 are arranged in the receiving area 612 in the left-to-right direction; each of the arranged pressure rollers 8 is mounted in the mounting hole 608, with its axis extending in the front-to-back direction, integrally connected to the pressure roller frame 6, and perpendicular to the vertical plates 605;

[0052] The left end of the pressure roller frame 6 is provided with a left hinged member hinged to the first lifting member 3; the left hinged member includes a suspension plate 601 symmetrical along the front-to-back direction, and a connecting shaft 602 is provided between the suspension plates 601, and the connecting shaft 602 is inserted between the vertical plate 605 and the suspension plate 601, so that the suspension plate 601 and the vertical plate 605 are kept fixed; the connecting shaft 602 not only fixes the suspension plate 601 and the vertical plate 605, but also increases the structural strength between the vertical plates 605. Since the left hinge hole 609 is a connecting hole and is subjected to a large tensile force, the connecting shaft 602 and the left hinge hole 609 are spaced apart, which can also improve the tensile strength of the left hinge hole 609 and avoid deformation or breakage of the outer side of the left hinge hole 609 due to excessive tension;

[0053] The hinged connection between the left end of the roller frame 6 and the front and rear sides of the lower crossbeam 7 is located outside the roller frame 6. That is, there is a distance of approximately 12-22 cm between the suspension plate 601 and the adjacent vertical plate 605. This ensures that while the roller 8 is mounted on the vertical plate 605, the diameter of the left hinge hole 609 at the left end of the roller frame 6 has sufficient space for connection with the control mechanism, thus preventing component layout congestion and interference. The suspension plate 601 is provided with a left hinge hole 609 that is hinged to the lower end of the first lifting member 3.

[0054] The right end of the roller frame 6 is provided with a right hinge member hinged to the second lifting member 17. The right hinge member of the roller frame 6 includes a reinforcing beam 604 fixedly connected between the vertical plates 605. The reinforcing beam 604 provides a hinge position for the right end of the roller frame 6 and also increases the structural strength between the vertical plates 605 at the right end of the roller frame 6.

[0055] A hinged vertical plate 11 is provided at the middle position of the upper end of the reinforcing beam 604. The fixing method between the hinged vertical plate 11 and the reinforcing beam is achieved as follows: a flat plate 614 is provided at the upper end of the reinforcing beam 604 to be fixed to the reinforcing beam 604. The flat plate 614 is directly welded to the reinforcing beam 604 and is provided with mounting screw holes 613. The hinged vertical plate 11 is welded to a transverse plate. A rib plate is welded to the flat plate to maintain the stability of the transverse plate and the hinged vertical plate 11. The transverse plate is screwed to the mounting screw holes 613 of the flat plate 614, so that the hinged vertical plate 11 and the reinforcing beam 604 are kept fixed.

[0056] The hinged vertical plate 11 is provided with a right hinge hole 1101 hinged to the lower end of the second lifting member 17, and the central axis of the right hinge hole 1101 extends in the front-to-back direction. That is to say, after the right end of the pressure roller frame 6 is hinged, it forms a stable triangular suspension with the two symmetrical left hinge holes 609. At the same time, since the central axis of the right hinge hole 1101 extends in the front-to-back direction, the pressure roller frame 6 can only swing in the left and right directions, and the movement trend in the front-to-back direction will be blocked, thereby preventing the pressure roller frame 6 from swinging arbitrarily in all directions.

[0057] like Figure 11 As shown, a pressure roller 8 is also installed in the mounting hole 608 at the middle position of each group of vertical plates 605. If the structural strength between each group of vertical plates is increased only by relying on the reinforcing beam 604 and the connecting shaft 602, the middle part of the vertical plate 605 will be easily deformed or even cracked due to the excessive tension at both ends of the pressure roller frame 6. In severe cases, the pressure roller 8 may fall off from the mounting hole 608. Therefore, a reinforcing shaft 606 is provided in the accommodating area 612 formed by each group of vertical plates 605, which is spaced from the mounting hole 608 in the left and right directions. The reinforcing shaft 606 is fixedly connected between each group of vertical plates 605. While improving the structural strength of the installation location of the pressure roller 8, it also reinforces and stabilizes the entire pressure roller frame 6.

[0058] like Figure 11 As shown, the pressure roller 8 is fixed in the mounting hole 608 of the vertical plate 605 in this way: the two ends of the pressure roller 8 are connected with flange covers 801 fixed axially relative to the pressure roller 8, and the center of the flange cover 801 extends along the axial direction to form a cylindrical support portion, and the pressure roller 8 and the cylindrical support portion are interlaced together and can rotate circumferentially around the cylindrical support portion; the flange cover 801 not only supports the pressure roller 8 in rotation, but also serves as a transition piece to keep the pressure roller 8 and the vertical plate 605 fixed. That is, the flange cover 801 is installed on the vertical plate 605, that is, by Through holes 802 are arranged at intervals along the circumferential direction, and a flange base 610 is fixedly mounted on the vertical plate 605 outside the mounting hole 608 of the vertical plate 605 and is concentric with the mounting hole 608. The flange base 610 is the mounting seat of the flange cover 801, and the flange base 610 is usually welded to the mounting hole 608; the flange base 610 is provided with flange screw holes 611 arranged at intervals along the circumferential direction, and threaded fasteners are passed through the through holes 802 and screwed into the flange screw holes 611 to connect the flange cover 801 and the vertical plate 605 together.

[0059] S5: Pre-installed lifting guide module; the lifting guide module includes a second crossbeam 24 fixedly mounted on the frame 1, and a second lifting member 17 is hingedly mounted below the second crossbeam 24. Specifically, a suspension hinge seat 20 is fixedly mounted below the second crossbeam 24, and a second lifting member 17 is mounted below the suspension hinge seat 20. The second lifting member 17 and the suspension hinge seat 20 are hinged together by a short pin 18, so that the second lifting member 17 can rotate relative to the suspension hinge seat 20 in the left and right directions; the second lifting member 17 is configured to lift and lower in the up and down directions by its own telescopic method. The second lifting member 17 can be a cylinder, thereby providing power for lifting and lowering the right end of the pressure roller frame 6.

[0060] like Figure 3-5As shown, the second lifting member 17 includes a retractable second lifting rod 1701, and the second lifting rod 1701 is fixedly connected to an inverted U-shaped plate 12 through a locking nut 27 at the bottom. The inverted U-shaped plate 12 forms an inverted U-shaped groove, which can accommodate the hinged vertical plate 11. That is to say, the inverted U-shaped plate 12 provides an articulated carrier for the second lifting rod 1701 to be hinged to the hinged vertical plate 11 at the right end of the pressure roller frame 6. When the second lifting member 17 is lifted and lowered by the extension and retraction of the second lifting rod 1701, the second lifting rod 1701 also drives the right end of the pressure roller frame 6 to be lifted and lowered synchronously through the inverted U-shaped plate 12.

[0061] like Figure 3-5 As shown, the right end of the pressure roller frame 6 is provided with a horizontal ear plate 603 symmetrical along the front-to-back direction, and a slot 607 is provided on the horizontal ear plate 603; the slot 607 is a waist-shaped hole; a support 19 symmetrical along the front-to-back direction is fixedly connected under the second crossbeam 24, and a second adjustment device hinged by a short pin 18 is provided under the support 19, so that the second adjustment device can rotate in the left and right directions relative to the second crossbeam 24; the second adjustment device includes a second adjusting screw 9 and a second adjusting nut 10, and the lower end of the second adjusting screw 9 passes through the slot 607 on the pressure roller frame 6. By rotating the second adjusting nut 10 to adjust the position of the lower end of the second adjusting screw 9, that is, by squeezing the horizontal ear plate 603 through the second adjusting nut 10, the horizontal degree of the right end of the pressure roller frame 6 is changed, so that the pressure roller 8 remains horizontal, and after adjustment, the second adjusting screw 9 and the right end of the pressure roller frame 6 are kept relatively fixed in the up and down directions through the contact between the second adjusting nut 10 and the horizontal ear plate 603.

[0062] S6: Install the pressure roller frame 6; hinge the lower ends of the first lifting member 3 and the second lifting member 17 to the left and right ends of the pressure roller frame 6, respectively, so that the pressure rollers 8 on the pressure roller frame are on the same horizontal line; specifically, the lower end of the first lifting member 3 is hinged to the left end of the pressure roller frame 6 as follows: a hinge shaft 29 is provided within the suspension plate 601 at the left end of the pressure roller frame 6, and an integrally formed end cap 30 is provided at the outer end of the hinge shaft 29. The end cap 30 is fixed to the vertical plate 605 of the pressure roller frame 6, and the hinge shaft 29 is hinged to the front and rear sides of the lower crossbeam 7;

[0063] Furthermore, if the right end of the pressure roller frame 6 is set like the left end, a crossbeam is installed under the second lifting member 17, and the hinged vertical plate 11 is set symmetrically on the left and right and hinged to the crossbeam, but this arrangement will make the structure of the right end of the pressure roller frame 6 complicated and crowded, the production cost will also increase, and the weight lifted by the second lifting member 17 will also become larger; therefore, only one right hinged member is fixedly connected to the right end of the pressure roller frame 6, and the right hinged member is the hinged vertical plate 11. The hinged vertical plate 11 is in the middle position in the front-to-back direction of the pressure roller frame 6, and the lower end of the second lifting member 17 is connected to the hinged vertical plate 11. 1 is hinged together as follows: at the right end of the roller frame 6, a pin 13 is installed in the right hinge hole 1101 on the hinged vertical plate 11. The pin 13 passes through the right hinge hole 1101 and hinges the inverted U-shaped plate 12 connected to the second lifting rod 1701 together. The hinged vertical plate 11 and the front and rear sides of the lower crossbeam 7 form three hinge points on the roller frame 6, thereby forming an isosceles triangle suspension structure on the roller frame 6. When these three hinge points are simultaneously subjected to upward force, the roller frame 6 can be stably suspended. The structure is simple and effective, and also saves space.

[0064] S7: The pressure roller 8 is raised and lowered and guided; the lifting and lowering of the pressure roller frame 6 is controlled by the first lifting member 3 and the second lifting member 17. During the lifting process, the hinged structure of the second lifting member 17 and the second crossbeam 24 causes the right end of the pressure roller frame 6 to swing slightly in the left and right directions when it is lifted and lowered, thereby preventing the left and right ends of the first lifting member 3 and the second lifting member 17 from getting stuck during the lifting process, thereby realizing the synchronous lifting and lowering of the left and right ends of the pressure roller frame 6.

[0065] like Figure 9-10 As shown, in an ideal state, the lifting speeds of the first lifting member 3 and the second lifting member 17 are the same, and the positions after lifting are also the same. That is to say, in an ideal state, the first lifting member 3 and the second lifting member 17 can be lifted and lowered at the same time. However, in actual situations, due to installation errors and processing errors, the first lifting member 3 and the second lifting member 17 cannot be lifted and lowered absolutely synchronously. That is to say, there are always different heights between the first lifting member 3 and the second lifting member 17 due to different lifting speeds, and when the first lifting member 3 and the second lifting member 17 are both cylinders, the different heights will cause the first lifting rod 301 and the second lifting rod 1701 to generate a deflection angle, so that the two generate an extrusion force with the inner wall of the cylinder body, which will cause the first lifting member 3 and the second lifting member 17 to easily get stuck when they are lifted and lowered synchronously. Therefore, in this embodiment, the second lifting member 17 and the second crossbeam 24 are set to be hinged and rotated. The specific implementation method is as follows:

[0066] like Figure 1-2As shown, when the first lifting member 3 and the second lifting member 17 rise or fall synchronously, due to the asynchronous lifting between the first lifting member 3 and the second lifting member 17, the left end of the pressure roller frame 6 rotates relative to the first lifting member 3 during lifting, and at the same time, the second lifting member 17 connected to the middle position in the front-to-back direction of the right end of the pressure roller frame 6 rotates in the left-right direction relative to the second crossbeam 24; the second adjusting screw 9 in the second adjusting device located on both sides of the right end of the pressure roller frame 6 in the front-to-back direction is hinged at the lower end of the second crossbeam 24, and when the second lifting member 17 starts to deflect, since the slot 607 is a waist-shaped hole, it provides sufficient swinging space for the second adjusting screw 9, so the second adjusting screw 9 will deflect in the slot 607; thereby preventing the first lifting member 3 and the second lifting member 17 from getting stuck during the lifting process;

[0067] like Figure 3-5 As shown, the right end of the roller frame 6 is provided with a horizontal ear plate 603 symmetrical along the front-to-back direction, and the horizontal ear plate 603 is welded to the vertical plate 605 through a rib plate, and a slot hole 607 is provided on the horizontal ear plate 603; the slot hole 607 is a waist-shaped hole, and its width is greater than the diameter of the second screw 9; a support 19 symmetrical along the front-to-back direction is fixedly connected below the second upper crossbeam 24, and a second adjustment device is provided below the support 19 hinged by a short pin 18, so that the second adjustment device can rotate in the left-right direction relative to the second upper crossbeam 24; the second adjustment device includes a second screw 9 The second adjusting nut 10 is located at the lower end of the second screw 9; the lower end of the second screw 9 passes through the slot 607 on the pressure roller frame 6. After the pressure roller frame 6 stops rising and falling, the second adjusting nut 10 is rotated to adjust the position of the lower end of the second screw 9, that is, the horizontal ear plate 603 is squeezed by the second adjusting nut 10 to change the horizontality of the right end of the pressure roller frame 6, so that the pressure roller 8 remains horizontal, and after adjustment, the second screw 9 and the right end of the pressure roller frame 6 are kept relatively fixed in the up and down directions through the contact between the second adjusting nut 10 and the horizontal ear plate 603.

[0068] like Figure 7-8As shown, for example, when the guiding method is applied to metal plate grinding equipment, an idler roller 28 is further provided below the pressure roller 8, and the idler rollers 28 are installed on the frame 1 at intervals; the idler rollers 28 are fixedly installed on the frame 1 through the supporting beams 103, and the supporting beams 103 are installed between each group of longitudinal beams 102 in the left and right directions; and the bearing seats 104 are fixedly installed above the supporting beams 103, and the idler rollers 28 are installed between the bearing seats 104, and the idler rollers 28 are fixed axially relative to the bearing seats 104 and can rotate freely in the circumferential direction; and the idler rollers 28 are aligned with the pressure roller 8 up and down; a rotatable brush roller 26 is provided below the middle position of the roller frame 6, and a pressure roller 8 is also installed on the roller frame 6 above the brush roller 26 to prevent the plate strip s from jumping upward when the brush roller 26 is brushing; a separate control is provided on the right side of the roller frame 6. The mechanism for raising and lowering the pressure roller 8, the only difference between this separate lifting mechanism and the lifting module is that the separate lifting mechanism installs the pressure roller 8 on the roller seat 25, and then fixes the roller seat 25 under the lower crossbeam 7, and aligns the pressure roller 8 with the roller 28 below, so that the conveying process of the plate strip s is smoother; a rotatable brush roller 26 is also provided between the roller frame 6 and the separate lifting mechanism, and an idler roller 28 is provided below to prevent the plate strip s from jumping downward when the brush roller 26 is brushing; two diagonally arranged brush rollers 26 constitute an upper and lower grinding device, and the brush rollers 26 are used to brush the two sides of the plate strip s respectively. Through the guiding method in this embodiment, the pressure roller frame 6 can be raised and lowered efficiently and quickly, thereby clamping the plate strip s so that it can be conveyed smoothly, so that the grinding treatment effect on both sides of the plate strip s meets the use requirements.

[0069] like Figure 1-8 As shown, the pull rod 22 fixedly connected below the first lifting member 3 and the guide rod 23 spaced apart from the first lifting member 3 have exposed portions between the first crossbeam 2 and the lower crossbeam 7. The guide rod 23 also has exposed portions above the first crossbeam 2. To prevent dust and debris from entering, a protective sleeve 15 is provided on the exposed portions between the pull rod 22, the guide rod 23 and the lower crossbeam 7. The protective sleeve 15 is in the shape of a retractable bellows. When the pull rod 22 and the guide rod 23 are lifted or lowered, the protective sleeve 15 is in close contact with the surfaces of the pull rod 22 and the guide rod 23, thereby ensuring the normal operation of the pull rod 22 and the guide rod 23.

[0070] The part of the guide rod 23 exposed above the first crossbeam 2 is provided with an inverted hollow shield 4. The shield 4 is a hollow cylinder that covers the exposed part. The lower end of the shield 4 has a radially extending ring, which is threadedly connected to the first crossbeam 2 through the ring, so that the shield 4 is fixedly connected to the first crossbeam 2. It is worth noting that the length of the shield 4 is greater than the maximum length of the guide rod 23 exposed. This prevents dust while also preventing the guide rod 23 from colliding or interfering with the shield 4 when moving up and down.

[0071] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
