Description

Technical Field

[0001] The present invention relates to a corrugated plate roller forming machine, and particularly to a roller gap automatic adjustment mechanism capable of adjusting the gap between rollers according to different products.

Background Art

[0002] A corrugated plate roller forming machine is equipment that applies pressure to sheet metal to form a corrugated plate with concavities and convexities. The corrugated plate roller forming machine mainly includes two side walls and a plurality of forming units. The two side walls are parallel, and the plurality of forming units are provided along the two side walls. Each forming unit includes a lower forming roller and an upper forming roller above the lower forming roller, and there is a gap through which the sheet metal passes between the upper forming roller and the lower forming roller. The flat sheet metal passes through the gap between the upper forming roller and the lower forming roller, and is pressed by the upper and lower forming rollers to be recessed, applying pressure to the flat sheet metal to form a corrugated plate with concavities and convexities.

[0003] However, the gap between the upper forming roller and the lower forming roller of the forming unit is set corresponding to the thickness of the sheet metal. The gap between the two forming rollers in the conventional forming unit cannot be automatically adjusted according to the thickness of the sheet metal. When the forming unit applies pressure to sheet metals of different thicknesses, the on-site operator needs to adjust and set it in advance according to the thickness of the sheet metal. Therefore, when using the conventional forming unit in the process of pasting a cotton material on the surface of a certain corrugated plate and the thickness of the product changes, manpower and time are required to manually adjust the gap between the forming rollers.

Summary of the Invention

[0004] In order to solve the problem that the conventional forming unit of the corrugated plate roller forming machine cannot automatically adjust the gap between the rollers, the present invention provides a roller gap automatic adjustment mechanism that achieves the purpose of automatically adjusting the gap between the rollers by providing a sensing unit to observe the product or determine the thickness of the product and transmitting a signal to the gap adjustment unit to adjust the gap between the forming rollers.

[0005] The automatic roller gap adjustment mechanism according to the present invention, which solves technical problems, A clearance adjustment unit comprising a drive unit, a transmission member, two adapter assemblies, and two screws, wherein the transmission member is connected to the drive unit and is rotatable under the drive of the drive unit, and the two adapter assemblies are each connected to two screws and the transmission member and are driveable to rotate the two screws, A limit unit comprising two limit switches and a touch assembly, wherein the two limit switches are electrically connected to the drive unit, the touch assembly is fixed to the transmission member, rotates with the transmission member, and is capable of selectively triggering one of the limit switches. A sensing unit including a sensing device electrically connected to the drive device, A mobile molding unit comprising a first molding roller, a second molding roller, and two bearing housings, wherein both ends of the second molding roller are movably provided to the two bearing housings, the two bearing housings are each coupled to the two screws, and each bearing housing is driveable to move the second molding roller relative to the first molding roller along the two screws.

[0006] The effect obtained by the technical means of this invention is that, after the automatic roller gap adjustment mechanism observes the product or determines the thickness of the product using the sensing device, the second molding roller moves along the screw relative to the first molding roller, controlling the gap adjustment unit to adjust the gap between the first molding roller and the second molding roller, and also stopping the operation of the gap adjustment unit using the limit unit, thereby making the gap between the first molding roller and the second molding roller a suitable size for the product to pass through. In this invention, by automatically adjusting the gap between the rollers according to the product, the manpower and time required of on-site workers can be reduced, and labor costs required for the process can be saved.

[0008] In order to better understand the technical features and practical effects of this invention and to enable its implementation according to the content of the invention, preferred embodiments as shown in the drawings will be described in detail below.

[0009] As shown in Figures 1 to 5, the automatic roller gap adjustment mechanism of the present invention includes a gap adjustment unit 10, a limit unit 20, a sensing unit 30, and a moving molding unit 40.

[0010] As shown in Figures 1 to 5, the gap adjustment unit 10 includes a drive unit 11, a bearing base 12, a transmission member 13, two adapter assemblies 14, and two screws 15. Specifically, the drive unit 11 includes a reduction gear 111 and a motor 112 connected to the reduction gear 111. The transmission member 13 is connected to the reduction gear 111 of the drive unit 11 and rotates by the reduction gear 111. The transmission member 13 is rod-shaped, with one end protruding from the reduction gear 111 and the other end protruding from the bearing base 12.

[0011] As shown in Figures 1 to 5, the two adapter assemblies 14 are each connected to two screws 15 and a transmission member 13. Specifically, each adapter assembly 14 includes a meshed output bevel gear 141 and an input bevel gear 142. The two output bevel gears 141 of the two adapter assemblies 14 are fixed to the transmission member 13 and rotatable with the transmission member 13, and the two input bevel gears 142 of the two adapter assemblies 14 are each fixed to two longitudinally mounted screws 15 and rotatable with the screws 15. In practice, each adapter assembly 14 can connect the transmission member 13 and the screws 15 with two meshed worm gears, and the present invention does not particularly limit the form of each adapter assembly 14.

[0012] As shown in Figures 1 to 5, the limit unit 20 includes two limit switches 21 and a touch assembly 22, the two limit switches 21 being electrically connected to the motor 112 of the drive unit 11, and the touch assembly 22 being fixed to the transmission member 13, rotating with the transmission member 13, and capable of selectively triggering one of the limit switches 21. Specifically, the touch assembly 22 includes a disk body 221 and two touch members 222, the disk body 221 being fixed to the transmission member 13 and having a circular contour, and the two touch members 222 being fixed to the disk body 221 and extending in opposite directions. More specifically, two connecting holes 223 are drilled in the disk body 221, each connecting hole 223 extending along the circular contour of the disk body 221 and becoming an arc-shaped elongated hole, and each touch member 222 is a bolt, with the two touch members 222 each passing through the two connecting holes 223 and being fixed to the disk body 221 by nuts.

[0013] As shown in Figures 1 to 5, the sensing unit 30 includes a sensing device 32, which is electrically connected to the motor 112 of the drive unit 11. In practice, the sensing device 32 may be a camera or surveillance camera that observes or determines the thickness of the product.

[0014] As shown in Figures 1 to 6, the automatic roller gap adjustment mechanism of the present invention can be mounted on a corrugated plate roller forming machine 60 which includes two parallel wheel walls 61 and two forming units 62. The drive unit 11 of the gap adjustment unit 10 of the present invention has a reduction gear 111 fixed to the top of one of the wheel walls 61, and a bearing base 12 fixed to the top of the other wheel wall 61. The transmission member 13 of the gap adjustment unit 10 is inserted into the reduction gear 111 and the bearing base 12 and spans the two wheel walls 61. In addition, the two limit switches 21 of the limit unit 20 of the present invention are each fixed to the same wheel wall 61 as the bearing base 12 by two assembly frames 24. The two forming units 62 are provided along the two wheel walls 61. Each molding unit 62 includes a power-transmitting lower molding roller 621 and a power-transmitting upper molding roller 622 located above it, wherein the lower molding roller 621 is parallel to the upper molding roller 622.

[0015] As shown in Figures 1 to 6, the movable molding unit 40 on the left side of the figure is located below the transmission member 13 of the gap adjustment unit 10 and includes a transmittable first molding roller 41, a second molding roller 42, and two bearing housings 43. The second molding roller 42 is located above the first molding roller 41 and is parallel to the first molding roller 41, and both ends of the second molding roller 42 are each provided to transmit power to the two bearing housings 43.

[0016] As shown in Figures 1 to 6, the two bearing housings 43 are each connected to the two screws 15, and each bearing housing 43 can move up and down along the corresponding screw 15. Specifically, each bearing housing 43 is screwed into the corresponding screw 15 by an insert and can further move up and down along the screw 15.

[0017] As shown in FIGS. 1 to 6, the sensing unit 30 includes a mounting frame 31. Both ends of the mounting frame 31 are coupled to two such vehicle walls 61, and the sensing device 32 is coupled to the mounting frame 31. The sensing unit 30 is located between the forming unit 62 adjacent to the moving forming unit 40. In the drawing, the sensing unit 30 is located on the right side of the moving forming unit 40.

[0018] As shown in FIGS. 1 to 6, when the sensing device 32 of the sensing unit 30 determines that the thickness of the product has changed, or the materials attached to the surface of the product are different. For example, when observing that a cotton material is attached to the surface of a corrugated plate and the thickness has changed, the sensing device 32 transmits a signal to the motor 112. The motor 112 operates to transmit power from the speed reducer 111 to the transmission member 13. The transmission member 13 drives the two screws 15 by two adapter assemblies 14. The two bearing boxes 43 drive the second forming roller 42 to move up and down along the screw 15 and move vertically with respect to the first forming roller 41, so that the gap between the first forming roller 41 and the second forming roller 42 can be adjusted.

[0019] As shown in FIGS. 4 to 8, for example, when the sensing device 32 senses that a cotton material is attached to the surface of a corrugated plate, the sensing device 32 controls the motor 112 to operate, so as to drive the two bearing boxes 43 so that the second forming roller 42 moves up along the screw 15, and the gap between the second forming roller 42 and the first forming roller 41 becomes larger. In addition, the transmission member 13 drives the touch assembly 22 to rotate clockwise. When one touch member 222 of the touch assembly 22 contacts one limit switch 21, the limit switch 21 transmits a signal to the motor 112 and controls the motor 112 to stop, so that the gap between the second forming roller 42 and the first forming roller 41 is suitable for the corrugated plate with the cotton material attached to pass through.

[0020] As shown in FIGS. 4 to 9, when the sensing device 32 senses that the cotton material is not attached to the surface of the corrugated plate, the sensing device 32 controls the motor 112 to operate, thereby driving the two bearing boxes 43 so that the second forming roller 42 descends along the screw 15, and the gap between the second forming roller 42 and the first forming roller 41 becomes smaller. The transmission member 13 drives the touch assembly 22 to rotate counterclockwise. When the other touch member 222 of the touch assembly 22 contacts the other limit switch 21, the limit switch 21 controls the operation of the motor 112 to stop, so that the gap between the second forming roller 42 and the first forming roller 41 is suitable for the corrugated plate to pass through without the cotton material being attached.

[0021] In the present invention, a sensing unit 30 is provided to observe and judge whether the thickness of the product or whether the cotton material is attached, transmit a signal, and control the gap adjustment unit 10 to operate. The gap adjustment unit 10 drives a second forming roller 42 that moves along the screw 15 with respect to the first forming roller 41, adjusts the gap between the two forming rollers 41 and 42, and after adjusting the gap between the two forming rollers 41 and 42 according to the product, controls the limit unit 20 to stop the operation of the gap adjustment unit 10, so that the gap between the first forming roller 41 and the second forming roller 42 is suitable for the product to pass through. Compared with the conventional forming unit that cannot automatically adjust the gap between the rollers, the present invention can adjust the gap between the rollers according to products of different thicknesses, eliminating the need for manual gap adjustment, saving the labor and time of on-site workers, and reducing the labor cost required for the process.

[0022] Furthermore, in a preferred embodiment of the present invention, since each screw 15 is provided in the vertical direction, each bearing housing 43 can move up and down along the corresponding screw 15, and the gap adjustment unit 10 drives the second molding roller 42 to move up and down in the vertical direction relative to the first molding roller 41, thereby creating a gap between the second molding roller 42 and the first molding roller 41 through which a product can pass, thus avoiding situations where, for example, a corrugated board product with cotton material attached comes into contact with the second molding roller 42 or the first molding roller 41 and damages the attached material.
