[0030] Embodiments

[0031] Reference Figures 1-6 The embodiment provides an adjustable rolling mill, which comprises a box body 110, two transmission shafts 120 movably arranged in the box body 110, the two transmission shafts 120 are movably arranged on the side wall of the box body 110 and connected with rolling mills 130, one of the rolling mills 130 movably sleeved with an eccentric mechanism 150, the eccentric mechanism 150 is connected with an adjusting mechanism 140, the adjusting mechanism 140 comprises an arc-shaped worm wheel plate 141 connected to the outer wall of the eccentric mechanism 150, the arc-shaped worm wheel plate 141 is meshed and connected with a worm 142, the worm 142 movably penetrates through the top of the box body 110 and is connected with a driven gear 160, the driven gear 160 is meshed and connected with a driving gear 170 movably arranged on the top of the box body 110, the top of the driving gear 170 is connected with a rotating handle 180, and the number of teeth of the driving gear 170 is less than that of the driven gear 160.

[0032] In the embodiment, when the roll gap is adjusted, the handle 180 is manually rotated to drive the driving gear 170 to rotate the driven gear 160, and then the worm 142 and the arc-shaped worm plate 141 are driven to rotate, and the eccentric mechanism 150 is also driven to rotate by a certain angle, so that the transmission shaft 120 in the interior is eccentrically displaced, and the corresponding transmission shaft 120 is driven to move close to the other transmission shaft 120, that is, the corresponding roller 130 is driven to move close to the other roller 130, so as to achieve the roll gap adjustment. During the adjustment process, the number of teeth of the driving gear 170 is less than the number of teeth of the driven gear 160, so that a force-saving lever structure is formed, and the handle 180 is more labor-saving when it is rotated. The handle 180 can be applied to manually adjust the heavy parts in the interior of the rolling mill, and the operation convenience is improved.

[0033] It should be noted that the handle 180 can be a hand wheel or a crank rocker, which is not limited here.

[0034] As an optional embodiment, the top of the worm 142 is connected with a first square column 190 located at the top of the box body 110, the driven gear 160 is provided with a first rectangular hole matched with the first square column 190, the top of the box body 110 is movably connected with a second square column 210, the driving gear 170 is provided with a second rectangular hole matched with the second square column 210, and the bottom of the handle 180 is provided with a rectangular blind hole 181 matched with the second square column 210.

[0035] In the embodiment, although the larger the difference between the number of teeth of the driven gear 160 and the driving gear 170 is, the more labor-saving it is, a speed reduction structure is also formed, which leads to a low adjustment efficiency. Therefore, the two factors need to be balanced. Therefore, the driven gear 160 of the embodiment can be sleeved on the first square column 190 through the first rectangular hole, and the driving gear 170 can be sleeved on the second square column 210 through the second rectangular hole. Therefore, different specifications of the driven gear 160 and the driving gear 170 can be selected according to the actual situation to meet the corresponding labor-saving requirements and adjustment efficiency requirements, and the universality is improved. Then, the rectangular blind hole 181 at the bottom of the handle 180 is aligned with the second square column 210 and inserted, so that the assembly is quickly completed. When the handle 180 is rotated, the second square column 210 is driven to rotate. Under the limiting cooperation of the square column and the rectangular hole, the driving gear 170 and the driven gear 160 are driven to rotate.

[0036] As an optional embodiment, the handle 180 is movably penetrated by a limiting pin 220, and the top of the box body 110 is provided with an arc-shaped clamping groove 111 matched with the limiting pin 220. The arc-shaped clamping groove 111 is concentric with the driving gear 170.

[0037] In the embodiment, when the adjustment is completed by rotating the rotating handle 180 by a corresponding angle, in order to prevent the rotating handle 180 from being deflected due to the influence of vibration, affecting the gap between the two rollers 130, the limiting pin 220 can be inserted into the arc-shaped clamping groove 111 after penetrating the rotating handle 180, and the rotating handle 180 can be prevented from being deflected by using the friction fit between the limiting pin 220 and the arc-shaped clamping groove 111, so as to ensure that the gap between the two rollers 130 does not change.

[0038] As an optional embodiment, the eccentric mechanism 150 includes a movable bearing 151 movably sleeved on the corresponding roller 130, and an eccentric sleeve 152 is sleeved on the movable bearing 151. The eccentric sleeve 152 is movably embedded in the side wall of the box body 110. The eccentric mechanism 150 is provided with two eccentric sleeves 152, and the two movable bearings 151 are sleeved on the same transmission shaft 120. The arc-shaped worm gear plate 141 is connected between the two eccentric sleeves 152.

[0039] In the embodiment, when the worm 142 drives the arc-shaped worm gear plate 141 to rotate, the eccentric sleeve 152 and the arc-shaped worm gear plate 141 can rotate as a whole. Due to the eccentric structure design of the eccentric sleeve 152, the movable bearing 151 inside the eccentric sleeve 152 can be eccentrically displaced, so as to drive the corresponding transmission shaft 120 to move close to the other transmission shaft 120, that is, to drive the roller 130 to move close to the other roller 130, so as to realize the adjustment of the roll gap. Meanwhile, two eccentric mechanisms 150 are provided, and the arc-shaped worm gear plate 141 is connected between the two eccentric mechanisms 150. When the arc-shaped worm gear plate 141 rotates, the two eccentric sleeves 152 can be driven to rotate at the same time, so that the movable bearing 151 and the transmission shaft 120 can be more stably displaced, the center of gravity is stable, and the stress is balanced.

[0040] It should be noted that the bottom of the worm 142 is movably connected to the inner bottom of the box body 110 through a bearing. Here, the two rollers 130 are arranged in an upper and lower manner, and the eccentric mechanism 150 is arranged on the lower roller 130. Since the two rollers 130 need to rotate synchronously, the upper roller 130 also needs to be sleeved with a movable bearing 151 to cooperate with the rotation thereof. When the rolling mill is running, the two transmission shafts 120 rotate, and under the cooperation of the corresponding movable bearings 151, the arc-shaped worm gear plate 141 will not rotate.

[0041] As an optional embodiment, the two eccentric sleeves 152 are movably embedded in the two inner side walls of the box body 110, and the outer walls of the two eccentric sleeves 152 are connected with connecting blocks 153. The arc-shaped worm gear plate 141 is detachably connected between the two connecting blocks 153.

[0042] In the embodiment, the two eccentric sleeves 152 are detachably connected with the arc-shaped worm wheel plate 141 through the connecting blocks 153, facilitating assembly and disassembly, reducing assembly difficulty and facilitating subsequent replacement of parts. Here, the connecting blocks 153 and the arc-shaped worm wheel plate 141 can be connected through bolts, or other detachable connection structures can be adopted.

[0043] As an optional embodiment, the gear set 230 is further included, the gear set 230 including a driving gear 231 and two transmission gears 232, the driving gear 231 being connected to one end of the transmission shaft 120 away from the roller 130, and the driving gear 231 being located outside the box body 110, and the two transmission gears 232 being located inside the box body 110 and being fixedly sleeved on the transmission shaft 120.

[0044] In the embodiment, the gear set 230 is used to drive the transmission shaft 120 to rotate. In operation, the driving gear 231 can be rotated from outside the box body 110, and the driving gear 231 needs to be matched with a power mechanism (for example, a combination of a motor and a driving gear) to drive the two transmission gears 232 to rotate, so as to drive the two transmission shafts 120 and the corresponding rollers 130 to rotate synchronously.

[0045] It should be noted that since the gap adjustment amount between the two rollers 130 is relatively small, the adjustment amount is within the tooth groove depth of the two transmission gears 232, so the two transmission gears 232 can still maintain the normal meshing relationship after adjustment. Therefore, during initial assembly, the two transmission gears 232 should be kept in meshing relationship, and the gap between the two transmission gears 232 should be as large as possible, so that the normal meshing of the two transmission gears 232 can still be adapted after the gap between the two transmission gears 232 is gradually reduced after subsequent multiple adjustments, to prevent jamming.

[0046] As an optional embodiment, the transmission gears 232 on the corresponding transmission shafts 120 are located between the two connecting blocks 153, which is compact in structure and reasonable in space utilization, and reduces the size of the rolling mill as much as possible.

[0047] As an optional embodiment, the end cover 240 can be detachably connected (through bolts) to one end of each of the two transmission shafts 120 extending out of the box body 110, and the end cover 240 is used to press the roller 130, facilitating replacement of the roller 130, and the roller 130 can be pressed after assembly to prevent deviation.

[0048] As an optional embodiment, a plurality of annular roller grooves 131 are formed on each of the two rollers 130, which can improve the use economy.

[0049] As an optional implementation, a bottom plate 250 is further included, one side of the bottom plate 250 is vertically connected with a back plate 260, a plurality of supporting base plates 270 are detachably connected on the bottom plate 250, the box body 110 is arranged on the top of the supporting base plates 270, and one side of the box body 110 away from the roller 130 is attached to the back plate 260.

[0050] In the embodiment, according to actual use, the supporting base plates 270 with corresponding height are selected to be installed on the bottom plate 250, that is, the installation height of the box body 110 is adjusted, so that the use scene of different height positions is adapted, and the versatility is improved. It should be noted that a plurality of screw holes can be formed in the back plate 260, the screw holes are connected with corresponding positioning holes on the box body 110 through bolts, so that the box body 110 with adjusted height is fixed at the corresponding height position of the back plate 260, and the bottom plate 250 is also fixedly arranged, so that the shaking during the operation of the rolling mill can be reduced.

[0051] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent flow transformation by using the content of the specification and the drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
