[0043] The core of the utility model is to provide a rocker arm type pinch roll device, which can effectively avoid the adverse effects of cooling water on the strip product coil and improve the product quality of the coiler; the utility model also provides a coiler applying the rocker arm type pinch roll device.

[0044] In order to make the personnel in the technical field better understand the utility model scheme, the utility model is further described in detail below in combination with the drawings and specific embodiments.

[0045] In the specific embodiments, as shown in Figure 1 , Figure 2 and Figure 4 , the rocker arm type pinch roll device provided by the utility model comprises a rack 10, a controller and a pinch roll assembly 101 arranged on the rack 10, and in combination with reference to Figure 5 , the pinch roll assembly 101 comprises a compression roller 102 and a support roller 103 arranged in alignment from top to bottom, the compression roller 102 and the support roller 103 are gap-fitted to allow the steel plate to pass through, the rack 10 is hingedly connected with a compression support 104, and the compression roller 102 is linked and arranged on the compression support 104.

[0046] The compression support 104 is also linked and arranged with a back spray assembly, the back spray assembly comprises a gas pump, a pneumatic circuit and a plurality of nozzles 105 arranged in sequence along the airflow direction and communicated in sequence, the nozzles 105 are arrayed on the compression support 104, and when the compression support 104 is located at the bottommost working position, the jet direction of the nozzles 105 is opposite to the conveying direction of the steel plate.

[0047] In the specific device working operation process, in the non-working state, the pressing support 104 is in the topmost working position, after the device starts to run and the rocker type pinch roll device enters the working state, the pressing support 104 moves downward, until each nozzle 105 moves synchronously to the adaptive position above the pinch roll assembly 101. During the operation of the device, when the steel plate moves through the nozzle 105 below after passing through the pinch roll assembly 101, the high-pressure airflow output by the air pump is delivered to the nozzle 105 through the pneumatic circuit, and the high-pressure airflow is sprayed out of each nozzle 105 and blown to the surface of the steel plate, so as to blow away the cooling water or other process water attached to the surface of the steel plate, thereby forming a water removal treatment on the surface of the steel plate, thereby effectively avoiding the adverse effects of the cooling water splashed or attached to the surface of the steel plate during the operation of the device due to the movement of the parts or the process residues, avoiding the problems of uneven temperature of the finished coil and poor surface quality of the strip caused by the residual cooling water, thereby effectively ensuring the product quality of the finished coil, and greatly improving the overall operation performance of the coiler and the product processing quality.

[0048] It is not difficult to understand that the design scheme of the rocker type pinch roll device mentioned in the scheme is improved and adjusted on the basis of the existing coiler and its supporting rocker type pinch roll device basic component structure, and the parts and working modes of the coiler and the rocker type pinch roll device not mentioned in the scheme can be understood by referring to the conventional technical application mode in the art, and will not be described in detail.

[0049] Generally, each structural component of the counter-spraying assembly can be arranged integrally on the pressing support 104, or can be installed separately on other parts of the rack 10. Strictly speaking, only the linkage arrangement of each nozzle 105 on the pressing support 104 is required. Generally, each nozzle 105 is arranged in a horizontal direction in a single row or double rows or multiple rows array on the pressing support 104 to ensure the blowing treatment effect of the cooling water on the steel plate. The pressing support 104 can be assembled on the rack 10 through a bearing seat, or can be assembled between the rack 10 through other hinge mechanisms that can realize smooth turning.

[0050] In addition, the jet direction of the nozzle 105 can be generally along the horizontal direction, or can be arranged at a significant angle with the horizontal direction, but no matter how it is arranged, it should be ensured that the main flow direction of the airflow sprayed out of the nozzle 105 is opposite to the conveying direction of the steel plate at the pinch roll assembly 101, so as to ensure the efficient and thorough blowing treatment of the cooling water attached to the surface of the steel plate.

[0051] Specifically, the pneumatic circuit includes the communicatingly matched flow guide pipe set 106, the pneumatic stop valve and the manual stop valve. During the operation of the device, the high-pressure gas output by the air pump is delivered to the nozzle 105 through the flow guide pipe set 106, and when the high-pressure gas output through the nozzle 105 blows the cooling water adhered to the surface of the steel plate, the air flow path of the flow guide pipe set 106 can be cut off or re-conducted by operating the closing or opening of the pneumatic stop valve or the manual stop valve, so as to meet the operation requirements of the device under different working conditions or to ensure the process operation needs under different processes. Generally, only one of the pneumatic stop valve and the manual stop valve needs to be operated to complete the overall on-off control of the pneumatic circuit, of course, both of them can be operated at the same time to ensure the on-off operation effect of the air flow path, and the pneumatic stop valve can also be flexibly controlled by the PLC controller or other control devices matched with the coiler. In actual application, the on-off control component composition and operation mode of the pneumatic circuit can be flexibly selected and adjusted according to different working conditions and process requirements.

[0052] More specifically, please refer to Figure 10 The downstream water collecting assembly 11 is fixedly arranged on the rack 10, and includes a water collecting box 111 arranged below the pinch roll assembly 101, and a water collecting pipe 112 in communication between the bottom of the water collecting box 111 and the circulating water pipeline 21 of the coiler. The top of the water collecting box 111 is provided with a water blocking cover 113, which is arranged downstream of the reverse blowing assembly along the air flow direction, and the bottom of the water blocking cover 113 is in communication with the water collecting box 111 through a water collecting hole 114.

[0053] With the continuous operation of the device, the cooling water involved in the whole roll system working process of the rocker type pinch roll device can be effectively blocked within a reasonable range by the water blocking cover 113, so as to prevent these cooling water from splashing to the outside of the device or to the devices such as the coiling cylinder which need to ensure a water-proof working environment, thereby ensuring the stability and safety of the corresponding device operation. The cooling water blocked by the water blocking cover 113 will move downward along the outer wall of the water blocking cover 113 and flow into the water collecting box 111 through the water collecting hole 114, and the cooling water collected in the water collecting box 111 will finally flow into the circulating water pipeline 21 of the coiler through the water collecting pipe 112, realizing the recycling of the cooling water.

[0054] Correspondingly, the water blocking cover 113 can be arranged on the top of the water collecting box 111, and the water blocking plate 115 can be arranged between the bottom of the water blocking cover 113 and the top of the water collecting box 111, so as to prevent the cooling water flowing between the water blocking cover 113 and the water collecting box 111 from overflowing to other positions of the device, and the water collecting hole 114 can be arranged at the edge of the water blocking plate 115, and it is appropriate to be arranged at the edge of the side of the water blocking cover 113.

[0055] On the other hand, please refer to Figure 6As shown, a splash-proof guide assembly 12 is provided on the top of the frame 10, and the splash-proof guide assembly 12 is positioned above the pinch roller assembly 101. The splash-proof guide assembly 12 includes a guide shroud 121 positioned downstream of the tangential direction of the roller of the pinch roller assembly 101. The interior of the guide shroud 121 has a guide cavity 122 with its open end facing the pinch roller assembly 101. A drain pipe 123 is provided on the side of the guide shroud 121, which connects the guide cavity 122 and the circulating water pipe 21 of the winding machine.

[0056] When the pinch roll assembly 101 rotates at high speed, the cooling water adhering to the rollers of the pinch roll assembly 101 will fly out along the tangential direction of the outer peripheral surface of the rollers. The arrangement of the guide shroud 121 is just right so that the cooling water flying out from the rollers of the pinch roll assembly 101 is blocked on the main structure of the guide shroud 121. The blocked cooling water flows down along the guide shroud 121 and collects, and is finally transported to the circulating water pipeline 21 of the winding machine through the diversion pipe 123, thus completing the anti-splash treatment and recycling of the cooling water.

[0057] It is easy to understand that the tangential direction of the rollers in the pinch roller assembly 101 mentioned above refers to the tangential direction of the outer circumferential surface of the rollers in the pinch roller assembly 101. In practical applications, considering that the two rollers of the pinch roller assembly 101 rotate in opposite directions, for the upper pressing roller 102 in the pinch roller assembly 101, the guide shroud 121 is positioned downstream of the tangential direction of the top outer wall of the pressing roller 102, that is, downstream of the steel plate conveying direction at the pinch roller assembly 101; and for the lower support roller 103 in the pinch roller assembly 101, the guide shroud 121 is positioned downstream of the tangential direction of the bottom outer wall of the support roller 103, which is also downstream of the steel plate conveying direction at the pinch roller assembly 101. This arrangement ensures that the guide shield 121 is positioned on the path of the cooling water spraying out from the rollers of the pinch roller assembly 101. This effectively blocks and guides the cooling water spraying out from the pinch roller assembly 101, preventing it from splashing onto the outside of the equipment or onto functional devices such as oil cylinders that require water isolation, thus affecting the operation of the corresponding devices. This ensures the overall stability and efficiency of the winding machine.

[0058] Correspondingly, the height of the top inner wall of the flow guide cavity 122 linearly decreases along the conveying direction of the steel plate, and the open end edge of the flow guide cavity 122 is fixedly connected with the rack 10. Since the arrangement position of the flow guide cover 121 is higher than that of the pinch roll assembly 101, the top inner wall of the flow guide cavity 122, that is, the contact surface against which the cooling water splashes, is arranged. The linearly changing height of the top inner wall of the flow guide cover 121 can make the top structure of the flow guide cavity 122 more conducive to the gradual downward movement and collection of the cooling water splashed and attached to the top inner wall of the flow guide cavity 122, and the drain pipe 123 is correspondingly arranged close to the bottom of the flow guide cavity 122. Therefore, such a structural layout can facilitate the more smooth and efficient discharge of the cooling water through the drain pipe 123.

[0059] On this basis, the top wall of the flow guide cover 121 has an observation hole 124 in communication with the flow guide cavity 122, and a transparent cover plate 125 is packaged on the observation hole 124. During the operation of the equipment, the workers can observe and understand the cooling water collection state and flow drainage condition in the flow guide cavity 122 in real time through the observation hole 124, so as to maintain or assist in adjusting the device when necessary. The transparent cover plate 125 can provide reliable shielding for the observation hole 124, avoid the cooling water in the flow guide cavity 122 from overflowing or splashing out through the observation hole 124, and at the same time, will not cause shielding to the observation of the workers through the observation hole 124, ensuring the normal work of the workers.

[0060] In addition, as shown in FIG. 1, Figure 7 As shown in FIG. 1, the rack 10 is provided with an upstream drainage assembly 13 arranged in position at the inlet end of the pinch roll assembly 101 along the conveying direction of the steel plate. The upstream drainage assembly 13 includes two upstream drainage bearing seats 131 symmetrically arranged on both sides of the pinch roll assembly 101 and an upstream drainage seat 132 connected between the two upstream drainage bearing seats 131.

[0061] The upstream drainage seat 132 includes a water guide plate 133 arranged in position below the pinch roll assembly 101 and a water collecting tank 134. The top end of the water guide plate 133 is closely fitted with the bottom of the pinch roll assembly 101, and the bottom end of the water guide plate 133 is connected with the water collecting tank 134. The bottom end of the water guide plate 133 is arranged in the same direction as the top end along the conveying direction of the steel plate. The water collecting tank 134 is arranged in the horizontal direction, and the two ends of the water collecting tank 134 are respectively connected with the circulating water pipe 21 of the coiler through upstream return water pipes 135. Generally, the upstream return water pipes 135 are selected as 45° hoses to meet the equipment arrangement requirements under most working conditions.

[0062] During the operation of the pinch roller assembly 101, the residual cooling water discharged from the rollers of the pinch roller assembly 101 will fall onto the guide plate 133. This residual water will gradually move down along the outer wall of the guide plate 133 and collect in the water collection tank 134. Then it will be transported to the circulating water pipeline 21 of the coiler through the upstream return water pipe 135 to complete the recovery and recycling of the cooling water.

[0063] Typically, multiple vertically extending water-blocking ribs 136 can be protruding from the water guide plate 133. Adjacent water-blocking ribs 136 are spaced apart to form a channel for water flow, allowing residual cooling water to flow and collect more smoothly downwards on the water guide plate 133. The number of water-blocking ribs 136 can be flexibly selected according to actual requirements. The ribs 136 can be evenly spaced or unequally spaced, as long as the arrangement meets the practical application needs of the rocker arm type pinch roller device.

[0064] Furthermore, please combine with, for example Figure 8 and Figure 9 As shown, an upstream water-blocking assembly 14 is provided upstream of the pinch roller assembly 101. The upstream water-blocking assembly 14 includes a water-blocking bearing seat 141 fixed on the frame 10 and an upper gate guide plate 142 hinged to the water-blocking bearing seat 141. A water-cutting plate 143 extending axially along the roller of the pinch roller assembly 101 is provided at the free end edge of the upper gate guide plate 142. When the upper gate guide plate 142 is in the top working position, the water-cutting plate 143 is in contact with and slides against the outer peripheral wall of the pressure roller 102 in the pinch roller assembly 101.

[0065] During the operation of the pinch roller assembly 101, when the steel plate passes between the two rollers of the pinch roller assembly 101, the upper gate guide plate 142 will swing around its hinge axis until the free end edge of the water-cutting plate 143 is in contact with the outer peripheral wall of the clamping roller 102 of the pinch roller assembly 101. After that, the working position of the water-cutting plate 143 is kept constant. By utilizing the sliding cooperation between the water-cutting plate 143 and the outer peripheral wall of the clamping roller 102 of the pinch roller assembly 101, the clamping roller 102 rotates along its fixed axis. The incoming cooling water can be blocked and scraped off the outer wall of the pressure roller 102 by the water cutting plate 143. The cooling water scraped off the pressure roller 102 will flow down gradually along the water cutting plate 143 and the inclined upper gate guide plate 142, so as to be transferred to the downstream coiler circulating water tank or other work stations, so as to avoid the cooling water adhering to the main structure and steel plate of the pinch roller assembly 101, thereby avoiding the adverse effects of cooling water residue on the moving parts and steel plate of the pinch roller assembly 101.

[0066] In addition, please refer to the following: Figure 9As shown, the upstream water-blocking assembly 14 also includes a lower valve guide plate 144 positioned below the upper valve guide plate 142. The lower valve guide plate 144 is hinged to the frame 10 via trunnions 145 at both ends. When the upper valve guide plate 142 is in the bottom working position, the water-cutting plate 143 contacts the lower valve guide plate 144 so that the top wall of the lower valve guide plate 144 is in contact with the top wall of the water-cutting plate 143. A water guide hole 146 communicating with the circulating water pipeline 21 of the winding machine is passed through the middle of the lower valve guide plate 144. After the water-cutting plate 143 completes the scraping treatment of the outer peripheral wall of the pinch roller assembly 101, the upper gate guide plate 142 rotates in the opposite direction around its hinge axis, so as to drive the water-cutting plate 143 to disengage from the contact with the outer wall of the pinch roller assembly 101 and swing synchronously until the outer edge of the water-cutting plate 143 reliably contacts the free end edge of the lower gate guide plate 144. Then, the upper gate guide plate 142, the water-cutting plate 143, and the lower gate guide plate 144 can be connected in sequence to form a water flow guiding structure, thereby guiding the water flow... The residual cooling water falling from the pinch roll assembly 101 is smoothly guided to the lower gate guide plate 144, and then discharged into the circulating water pipeline 21 of the coiler through the water guide hole 146. This realizes the recovery and recycling of cooling water, and effectively avoids the residual cooling water in the main structure of the pinch roll assembly 101 and its related auxiliary devices. This eliminates the adverse effects of residual cooling water on the overall operational stability of the rocker arm pinch roll device and even the coiler and the quality of the steel plate products.

[0067] In actual assembly applications, the water guide holes 146 can be arranged in a regular array as shown in the figure, or they can be arranged in an irregular or unequal interval. However, it is necessary to ensure that each water guide hole 146 can be smoothly connected to prevent the cooling water from accumulating on the lower valve guide plate 144 or even overflowing abnormally. This overflowing cooling water would seriously have an adverse effect on the stable operation of the pinch roll assembly 101 and the product quality of the steel plate.

[0068] In a specific embodiment, the coiling machine provided by this utility model includes a machine body 20 and a rocker arm type pinch roller device disposed on the machine body 20, wherein the rocker arm type pinch roller device is as described above. The rocker arm type pinch roller device of this coiling machine can effectively avoid the adverse effects of cooling water on the finished strip coil and improve the quality of the finished strip coil product of the coiling machine.

[0069] It should be noted that, in specific applications, in addition to the rocker arm type pinch roller device and circulating water pipeline 21, the winding machine provided in this solution will also be equipped with other functional devices or components to match the equipment operation requirements under actual working conditions. The specific structure and working performance of these functional devices and components can be directly understood by referring to the conventional technology in this field, and will not be elaborated here.

[0070] Additionally, please refer to the following: Figure 3As shown, the body 20 is provided with a recycling flow guide assembly 15, which includes a water blocking panel 151 vertically arranged and positioned at the inlet side of the pinch roll assembly 101, and a water return flow guide groove 152 positioned below the water blocking panel 151, and the end of the water return flow guide groove 152 is connected with the circulating water pipeline 21 through a water return flow guide pipe 153.

[0071] During the operation of the coiler device, the water blocking panel 151 can block the cooling water matched with the operation of all the roll systems in the coiler device within a reasonable range, so as to prevent the cooling water from splashing to other working components or devices to cause corrosion and wear of the components by the cooling water, or cause the adverse effects such as water scale adhesion and failure of the water sealing structure, thereby effectively improving the operation stability of the device and the overall service life of the related components. The cooling water blocked on the water blocking panel 151 flows downward along the water blocking panel 151 and gradually collects in the water return flow guide groove 152, and then the cooling water in the water return flow guide groove 152 can be discharged into the circulating water pipeline 21 through the water return flow guide pipe 153, so as to realize the recycling and utilization of the cooling water.

[0072] As can be seen from the above, in the rocker arm type pinch roll device provided in the utility model, in the non-working state during the working operation process, the pressing support is in the topmost working position, after the device starts to operate and the rocker arm type pinch roll device enters the working state, the pressing support moves downward until the pressing roll reaches the upper and lower position matching position with the supporting roll, and at this time, each nozzle moves synchronously to the matching position above the pinch roll assembly. During the operation of the device, when the steel plate moves through the nozzle below after passing through the pinch roll assembly, the high-pressure airflow output by the air pump is delivered to the nozzle through the pneumatic circuit, the high-pressure airflow is sprayed out through each nozzle and blown to the surface of the steel plate, so as to blow away the cooling water or other process water attached to the surface of the steel plate, thereby forming a blowing and water removal treatment on the surface of the steel plate, thereby effectively avoiding the adverse effects of the cooling water splashing or attached to the surface of the steel plate due to the movement of the components or the process residues during the operation of the device, avoiding the problems such as uneven temperature of the finished coil of the strip and poor surface quality caused by the residual cooling water, thereby effectively ensuring the product quality of the finished coil of the strip, and greatly improving the overall operation performance of the coiler and the product processing quality.

[0073] The utility model also provides a coiler, and the rocker arm type pinch roll device thereof can effectively avoid the adverse effects of the cooling water on the finished coil of the strip and improve the product quality of the finished coil of the strip of the coiler.
