[0022] This utility model provides, for example Figures 1 to 4 The cooling device shown includes a cooling tank 1. A slide rail 21, fixedly connected to the cooling tank 1, is horizontally placed inside the cooling tank 1. The slide rail 21 has an isosceles trapezoidal cross-section along the vertical direction. Two opposing sliding support plates 5 are installed on the slide rail 21. Each support plate 5 has a limiting groove that matches the slide rail 21; the limiting groove is a through groove. The slide rail 21 passes through the two limiting grooves, and the two support plates 5 are in a limiting sliding engagement with the slide rail 21.

[0023] A first drive assembly is installed inside the cooling pool 1, and the first drive assembly is connected to two support plates 5. The first drive assembly includes a bidirectional lead screw 3, which is rotatably connected to the cooling pool 1. Each of the two threaded sections of the bidirectional lead screw 3 is threaded to a connecting plate 4, and the two connecting plates 4 correspond one-to-one with the two support plates 5. Each connecting plate 4 is fixedly connected to the bottom end of its corresponding support plate 5. A first motor 2 is fixedly installed on the cooling pool 1, and the output shaft of the first motor 2 passes through the cooling pool 1 and is coaxially and fixedly connected to the bidirectional lead screw 3.

[0024] Each of the two support plates 5 has a circular through hole, and the two circular through holes are horizontally opposite each other. A turntable 7 is coaxially installed in each of the two circular through holes, and both turntables 7 are rotatably connected to their respective support plates 5. A circular insertion hole is formed in the center of each of the two turntables 7 along the axial direction. The two ends of the roller shaft correspond one-to-one with the two circular insertion holes, and each end of the roller shaft coaxially passes through the corresponding circular insertion hole.

[0025] A second drive assembly is installed on one of the support plates 5. The second drive assembly is connected to the turntable 7 on the support plate 5 to drive the turntable 7 to rotate.

[0026] The second drive assembly includes a second motor 16, which is fixedly mounted on one of the support plates 5. A turntable 7 on the support plate 5 is coaxially fixedly connected to an external gear ring 6. A gear 15 is fixedly sleeved on the output shaft of the second motor 16, and the gear 15 meshes with the external gear ring 6.

[0027] Two clamping plates 14 are installed on each of the two turntables 7 to clamp and fix the ends of the roll shafts. The two clamping plates 14 located on the same turntable 7 are symmetrically arranged about the circular insertion holes on the turntable 7 and are slidably connected to the turntable 7. Each clamping plate 14 slides radially along the turntable 7, and each clamping plate 14 includes an arc-shaped clamping block that matches the end of the roll shaft, an arc-shaped plate fixed to the outer curved surface of the arc-shaped clamping block, two sliding plates 12 that are radially parallel to the arc-shaped plate and fixed to the outer curved surface of the arc-shaped plate, and a U-shaped frame that is fixedly connected to the ends of the two sliding plates 12 away from the arc-shaped plate.

[0028] The two slide plates 12 are parallel to each other, and two guide grooves are formed on the turntable 7. The two guide grooves are connected to the circular insertion holes on the turntable 7. Both guide grooves pass through the turntable 7 along the axial direction. The two slide plates 12 correspond one-to-one with the two guide grooves, and each slide plate 12 is slidably installed into the corresponding guide groove.

[0029] The U-shaped frame is fitted onto the disc between the two guide grooves and simultaneously slides and limits the disc.

[0030] Both turntables 7 are equipped with linkage components, and the two clamping plates 14 on each turntable 7 are connected to the rollers via the linkage components. The two turntables 7 are located between the two linkage components.

[0031] We will now describe one linkage component as an example, and the other one is the same as this linkage component.

[0032] The linkage assembly includes a push plate 8 and connecting rods 11. The push plate 8 is hinged to the two clamping plates 14 via connecting rods 11, and the rollers abut against the push plate 8 for transmission. In this embodiment, the number of connecting rods 11 is preferably four, and the four connecting rods 11 are divided into two parallel groups of two, with the two connecting rods 11 in the same group being symmetrically distributed in a figure-eight shape.

[0033] The following is a detailed description of one set as an example; the other set is the same. Two connecting rods 11 correspond one-to-one with two clamping plates 14, and both connecting rods 11 are hinged to the corresponding sliding plate 12 of the clamping plate 14. The hinge configuration is as follows: two hinge seats are fixedly installed on the sliding plate 12, and a rotating shaft 13 is rotatably installed between the two hinge seats; the connecting rods 11 are fixedly connected to the rotating shaft 13.

[0034] The ends of the two connecting rods 11 away from the hinged slide plate 12 are both hinged to the push plate 8. Two horizontal and parallel guide rods 9 are fixedly installed on the turntable 7. The two guide rods 9 pass through the push plate 8, and the push plate 8 and the two guide rods 9 are in a limiting sliding fit.

[0035] A spring 10 is fitted on each of the two guide rods 9. One end of each spring 10 is fixedly connected to the turntable 7, and the other end of each spring 10 is fixedly connected to the push plate 8.

[0036] A water outlet pipe 19 is fixedly installed on the cooling pool 1, and multiple nozzles 20 are fixedly installed on the water outlet pipe 19, each nozzle 20 facing the roller. A water pump 17 is fixedly installed on the cooling pool 1, and the outlet of the water pump 17 is connected to the water outlet pipe 19 through a water pipe 18. The water pump 17's suction port is connected to a water tank.

[0037] Two filter tanks 22 are installed inside the cooling pool 1. The two filter tanks 22 are located below the slide rail 21 and are arranged along the direction of the slide rail 21. The two filter tanks 22 are symmetrically arranged and their opposite ends are fixedly connected to the cooling pool 1. The opening of each filter tank 22 faces upward, and the bottom of each filter tank 22 is a filter plate.

[0038] The bidirectional lead screw 3 is placed horizontally between the two filter tanks 22 and below the slide rail 21.

[0039] Working principle: When the roll needs to be cooled, the roll is first hoisted between the two support plates 5 so that the two shaft ends of the roll are coaxially aligned with the corresponding circular insertion holes.

[0040] Next, the first motor 2 is started. The output shaft of the first motor 2 drives the bidirectional lead screw 3 to rotate, and the bidirectional lead screw 3 pushes the two connecting plates 4 to move closer together. The two connecting plates 4 then drive the two support plates 5 to slide closer together along the slide rail 21.

[0041] During this process, the two support plates 5 move relative to the roll. The two shaft ends of the roll are inserted into the corresponding circular holes relative to the two support plates 5. As the two support plates 5 continue to slide, the two shaft ends of the roll contact and abut against the push plates 8 behind the corresponding circular holes. At this time, the two push plates 8 are stationary relative to the roll, but move relative to the support plates 5.

[0042] Then, the push plate 8 stretches the connected spring 10, and at the same time pulls the two connecting rods 11 in the same group to rotate closer. During this process, the connecting rods 11 in the two groups pull the two clamping plates 14 to slide closer until they clamp and press against the roll.

[0043] Afterwards, the first motor 2 is shut down, and the second motor 16 and water pump 17 are started. The output shaft of the second motor 16 drives the gear 15 to rotate, the gear 15 drives the external gear ring 6 to rotate, and the external gear ring 6 drives the connected turntable 7 to rotate. The turntable 7 drives the two clamping plates 14 to rotate, and the two clamping plates 14 drive the rollers to rotate. During this process, the turntable 7 drives the push plate 8 to rotate through the two guide rods 9, and the two push plates 8 drive the rollers to rotate.

[0044] At the same time, the water pump 17 draws coolant from the water tank, and the coolant enters the outlet pipe 19 through the water pipe 18. The coolant in the outlet pipe 19 is sprayed onto the rolls through the nozzle 20 to perform the cooling operation.

[0045] After cooling is complete, the first motor 2 is restarted, and the output shaft of the first motor 2 reverses. The two connecting plates 4 move away and drive the two support plates 5 to slide away. At the same time, the spring 10 contracts, and the turntable 7 pushes the two connecting rods 11 in the same group to rotate away from the connecting rods 11 in the two groups, pushing the two clamping plates 14 to slide away from the shaft end of the roll.

[0046] When spring 10 contracts to its natural length, turntable 7 pushes pusher plates 8 to move synchronously via spring 10. At this time, the two pusher plates 8 move away from the shaft ends of the rollers.

[0047] Once the two ends of the roll slide out of the corresponding circular perforations, the first motor 2 is turned off and the roll is lifted out of the cooling pool 1.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
