[0041] Reference Figures 1-5 The utility model discloses an embodiment provides a kind of heavy roll line cold-rolled strip steel scratch-preventing guide plate table device, for conveying strip steel, including guide plate frame 1, guide plate frame 1 has conveying passage 101, conveying passage 101 has conveying inlet 102 and conveying outlet 103, define conveying inlet 102 to the direction of conveying outlet 103 as transverse, horizontal direction is perpendicular to the direction of transverse as longitudinal, guide plate frame 1 has curb portion 104, curb portion 104 is set up in pairs, respectively located the longitudinal both sides of conveying passage 101;Conveying roller 2 rotation is arranged in the bottom of conveying passage 101, and rotation axis is along longitudinal, conveying roller 2 is used for with the bottom of strip steel rolling abutment.

[0042] In the embodiment, the surface material of the conveying roller 2 is neoprene, which is relatively soft to avoid scratching the strip steel. During operation, the strip steel enters the conveying passage 101 from the conveying inlet 102 and rolls against the conveying roller 2 at the bottom. The conveying roller 2 rotates actively, driving the strip steel to move along the transverse direction from the conveying inlet 102 to the conveying outlet 103. The curb portions 104 on both sides prevent the strip steel from shifting longitudinally during movement. The rolling contact between the conveying roller 2 and the bottom of the strip steel converts sliding friction into rolling friction, significantly reducing friction and effectively reducing wear on the surface of the strip steel. The paired curb portions 104 ensure that the strip steel moves stably along the predetermined transverse path during conveying, avoiding damage caused by deviation. The actively rotating conveying roller 2 provides stable power, making the conveying of the strip steel more smooth and improving production efficiency. By reducing scratches and wear on the surface of the strip steel, the surface quality of the cold-rolled strip steel is guaranteed, and the product's pass rate and market competitiveness are improved.

[0043] Further, the conveying roller 2 is a plurality of, and the plurality of conveying rollers 2 are arranged in groups in the transverse direction, and the conveying rollers 2 are also arranged in groups in the longitudinal direction. The plurality of conveying rollers 2 adjacent in the longitudinal direction rotate coaxially, and the plurality of conveying rollers 2 adjacent in the longitudinal direction are drivingly connected.

[0044] In the embodiment, when the strip steel enters the conveying passage 101, a driving device such as a motor drives one group of conveying rollers 2 to rotate. The driving connection of the conveying rollers 2 enables all the conveying rollers 2 to rotate synchronously, supporting and conveying the strip steel together, so that it moves smoothly from the conveying inlet 102 to the conveying outlet 103. The arrangement of multiple conveying rollers 2 in the transverse and longitudinal directions can provide more uniform support for the strip steel, reducing deformation and damage caused by excessive local pressure. The driving connection of adjacent conveying rollers 2 ensures the synchronous rotation of all conveying rollers 2, keeping the strip steel stable during conveying and avoiding pulling and scratching caused by speed differences. Multiple groups of conveying rollers 2 arranged in the transverse direction can adapt to strip steels of different widths, improving the versatility of the guide plate table device. Uniform support and synchronous conveying action greatly improve the stability of the entire conveying process, which is beneficial to ensuring product quality and production continuity.

[0045] Further, the guiding side plates 3 are arranged in pairs, two guiding side plates 3 are located in the conveying channel 101 and between the two blocking edge portions 104, and a first guiding space 301 is formed between the two guiding side plates 3, the first guiding space 301 has a transverse flared section 302 and a straight conveying section 303, the transverse flared section 302 is located on the side close to the conveying inlet 102, and the straight conveying section 303 is located on the side close to the conveying outlet 103.

[0046] In this embodiment, when the strip steel enters the first guiding space 301 from the conveying inlet 102, it first passes through the transverse flared section 302, and the wider inlet facilitates smooth entry of the strip steel. As the strip steel continues to move, it enters the straight conveying section 303, where it is gradually adjusted to the correct conveying position and conveying posture, and then passes through the conveying outlet 103. The design of the first guiding space 301, especially the cooperation of the transverse flared section 302 and the straight conveying section 303, can effectively guide the strip steel to accurately enter the conveying channel 101 and maintain a stable conveying direction. The transverse flared section 302 facilitates the initial entry of the strip steel, and even if the strip steel enters with a slight deviation in position, it can still be smoothly guided in, improving the adaptability of the device to deviations in the entry position of the strip steel. Through the constraint of the guiding side plates 3, the possibility of deviation of the strip steel during conveying is significantly reduced, further reducing the friction and scratching of the strip steel with the guide plate table.

[0047] Further, the guiding top plate 4 is located in the conveying channel 101 and at the top of the first guiding space 301, and the conveying roller 2 is located at the bottom of the guiding top plate 4, the guiding top plate 4 and the guiding side plate 3 form a first guiding channel 401 by enclosing the first guiding space 301, and the first guiding channel 401 has a vertical flared section 402, both the vertical flared section 402 and the transverse flared section 302 lead to the straight conveying section 303.

[0048] In this embodiment, when the strip steel enters from the conveying inlet 102, it first passes through the transverse flared section 302 and the vertical flared section 402, these two flared sections provide a larger space for the entry of the strip steel, facilitating the smooth entry of the strip steel into the first guiding channel 401. Subsequently, the strip steel is stably conveyed in the straight conveying section 303 until it is sent out from the conveying outlet 103. The closed first guiding channel 401 formed by the guiding top plate 4 and the guiding side plate 3 realizes all-around guiding and constraint of the strip steel, further improving the accuracy and stability of the guiding. The arrangement of the transverse flared section 302 and the vertical flared section 402 greatly reduces the difficulty of strip steel feeding, even if there is a certain deviation in the feeding position and angle, the strip steel can still smoothly enter the guiding channel. The closed channel structure can effectively prevent the strip steel from vertically jumping during conveying, reducing the collision and friction of the strip steel with the conveying components and reducing the risk of scratching.

[0049] Further, the device further comprises a receiving roller 5, which is rotatably and vertically movably arranged relative to the guide frame 1, is located on the side of the plurality of conveying rollers 2 close to the conveying inlet 102, has a diameter larger than that of the plurality of conveying rollers 2, and has a rotation axis parallel to the rotation axes of the plurality of conveying rollers 2.

[0050] In the embodiment, when the strip steel enters from the conveying inlet 102, it first contacts the receiving roller 5 at a higher position. The receiving roller 5 is vertically movable to adapt to different thicknesses of the strip steel and guides the strip steel to enter the conveying passage 101 at a gentler angle during rotation with the higher position. The vertical movement of the receiving roller 5 enables it to adapt to different thicknesses of the strip steel, improving the versatility of the device. Before the strip steel enters the area of the conveying rollers 2, the guidance and transition by the receiving roller 5 make the conveying of the strip steel more stable, reducing impact and friction. The larger diameter provides stronger support, which helps to prevent the strip steel from sagging or deforming at the inlet. In addition, since the top of the receiving roller 5 is higher than the conveying rollers 2, the strip steel can enter the conveying passage 101 at a gentler angle, reducing the risk of bending or scratching due to an excessively large angle, and improving the stability and reliability of the conveying.

[0051] Further, the guide frame 1 has a vertical guide groove 105, and further comprises a sliding block 6, the receiving roller 5 is rotatably arranged on the sliding block 6, and the sliding block 6 is vertically movably arranged in the guide groove 105; a first elastic member 7 has one end acting on the bottom wall of the guide groove 105 and the other end acting on the sliding block 6, providing a force for upward sliding reset of the sliding block 6.

[0052] In the embodiment, when the strip steel of different thicknesses enters the conveying passage 101, the strip steel presses down the receiving roller 5, causing the sliding block 6 to slide downward along the guide groove 105 and compress the first elastic member 7. After the strip steel passes through, the elastic restoring force of the first elastic member 7 pushes the sliding block 6 to slide upward and reset, causing the receiving roller 5 to return to the initial position. The cooperation of the sliding block 6 and the first elastic member 7 enables the receiving roller 5 to automatically adjust the height according to the thickness of the strip steel, adapting to different specifications of the strip steel and improving the versatility of the device. The first elastic member 7 ensures that the sliding block 6 can be reset smoothly and quickly, preparing for the next entry of the strip steel and improving the work efficiency. During the process of the strip steel pressing down the receiving roller 5, the first elastic member 7 acts as a buffer, reducing the instantaneous impact force between the strip steel and the receiving roller 5 and protecting the strip steel and the equipment. The position stability of the receiving roller 5 during the working process is ensured, so that the conveying of the strip steel is more stable and reliable, reducing the possibility of failure.

[0053] Further, the first rotating rod 8 is swingingly arranged on the baffle part 104, and the rotating shaft of the first rotating rod 8 is parallel to the rotating shaft of the bearing roller 5; the pressing roller 9 is rotatably arranged at one end of the first rotating rod 8, and the first rotating rod 8 is used to drive the eccentric swing of the pressing roller 9, and the pressing roller 9 is configured to abut against the upper surface of the strip steel after being driven to swing by the first rotating rod 8.

[0054] In the embodiment, when the strip steel passes through the conveying channel 101, the first rotating rod 8 drives the eccentric swing of the pressing roller 9, so that the pressing roller 9 abuts against the upper surface of the strip steel, and a certain pressure is applied to the strip steel, thereby stabilizing the position of the strip steel. The abutment of the pressing roller 9 against the upper surface of the strip steel can effectively prevent the strip steel from jumping up and down or deviating during the conveying process, thereby ensuring the stability of the strip steel conveying. By applying pressure, the vibration of the strip steel during the conveying process is reduced, the collision and friction between the strip steel and the conveying components are reduced, and the possibility of scratching is further reduced. Due to the swing characteristics of the first rotating rod 8, the pressing roller 9 can adapt to strip steels of different widths, thereby improving the universality of the device. In cooperation with the baffle part 104 and the conveying roller 2, the guiding effect on the strip steel is further enhanced, thereby ensuring that the strip steel is conveyed along the correct path.

[0055] Further, the first crank 10 is hingedly connected to the rotating shaft of the first rotating rod 8 at one end; one end of the first connecting rod 11 is hingedly connected to the sliding block 6, and the other end of the first crank 10 and the first connecting rod 11 is hingedly connected, and the sliding block 6 is configured to drive the eccentric swing of the pressing roller 9 through the first connecting rod 11 and the first crank 10 after being lifted and slid downward.

[0056] In the embodiment, when strip steels of different thicknesses enter the conveying channel 101, the strip steels press the bearing roller 5 downward, so that the sliding block 6 slides downward along the guide groove 105. The downward movement of the sliding block 6 drives the first crank 10 to rotate through the first connecting rod 11, and then drives the eccentric swing of the pressing roller 9 through the first rotating rod 8. When the strip steel just enters the conveying channel, the initial swing of the pressing roller 9 can pull the just-entered strip steel forward by a certain distance, so that the strip steel more smoothly enters the conveying position. In the subsequent conveying process, the pressing roller 9 abuts against the upper surface of the strip steel, thereby applying a certain pressure to the strip steel, thereby stabilizing the position of the strip steel. When the strip steel passes through, the sliding block 6 is lifted and reset under the action of the first elastic member 7, and the pressing roller 9 returns to the initial position through the above-mentioned linkage structure. Through the linkage of the sliding block 6, the first connecting rod 11, the first crank 10 and the first rotating rod 8, the lifting of the bearing roller 5 and the swing of the pressing roller 9 are realized in a coordinated manner, so that the operation of the device is more coordinated and efficient. The thickness of the strip steel can automatically trigger the swing action of the pressing roller 9, without the need for additional control devices, thereby reducing the cost and operation complexity. The lifting of the sliding block 6 and the swing of the pressing roller 9 are matched with each other, thereby further enhancing the stability control of the strip steel conveying, and reducing the shaking and deviation of the strip steel during the conveying process.

[0057] Further, the one-way bearing is arranged on the rotating shaft of the pressing roller 9.

[0058] In the embodiment, when the strip steel just enters the conveying channel, the one-way bearing restricts the rotation of the compression roller 9, so that frictional abutment between the compression roller 9 and the strip steel is generated, thereby being capable of pulling the strip steel forward. In the subsequent normal conveying process, the one-way bearing no longer restricts the rotation of the compression roller 9, and the compression roller 9 can freely rotate with the movement of the strip steel. The rotation is restricted only at the initial feeding stage, unnecessary friction and wear of the compression roller 9 in the whole conveying process are reduced, and the service life of the compression roller 9 is prolonged.

[0059] Further, the first bending roller 13 and the second bending roller 14 are further included, the first bending roller 13 and the second bending roller 14 are both rotationally arranged on the guide plate frame 1 and located at one side of the conveying outlet 103, and the first bending roller 13 and the second bending roller 14 form a bending gap 1401 therebetween, and the strip steel is used to pass through the bending gap 1401 after leaving the conveying channel 101 from the conveying outlet 103.

[0060] In the embodiment, after the strip steel leaves the conveying channel 101 from the conveying outlet 103, the strip steel enters the bending gap 1401 between the first bending roller 13 and the second bending roller 14. With the continuous movement of the strip steel, the strip steel is deformed according to a predetermined bending angle and shape under the action of the bending gap 1401. The bending gap 1401 formed by the first bending roller 13 and the second bending roller 14 is capable of accurately controlling the bending angle and shape of the strip steel, and guaranteeing the consistency and accuracy of the bending quality. The continuous bending process does not need additional adjustment and stop, and the production efficiency is improved.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and all of them should be covered in the scope of the claims of the present application.
