Description

Technical Field

[0001] The invention relates to the technical field of roll forming equipment, and in particular to an automated roll forming production line. Background Art

[0002] Rolling forming is a commonly used pottery making process. This process has evolved from spin forming and can be divided into two types: internal rolling method and external rolling method. It mainly uses a rolling machine to extrude the clay in the rotating mold to obtain a dense and uniform green body. This process has the advantages of low cost, high precision and high production efficiency. It is widely used in the manufacture of daily necessities such as tableware, flower pots, and lamps. In the rolling forming production line, the green body needs to be dried after green body making. In order to ensure the drying effect, the process is usually carried out in multiple times. The interval between two dryings needs to be cooled and left to stand for a period of time to improve the strength and wear resistance of the product. The mold after taking the green body also needs to be dried again before it can be put into use next time. Although the traditional production line can automatically complete the rolling forming process of the green body, the subsequent drying, mold opening, and green body taking operations still require manual assistance, which consumes a lot of manpower costs and reduces production efficiency. In addition, due to the complexity of the above drying process, manual transfer and loading and unloading of molds are prone to errors and damage. A new production line is needed to solve the above problems. Summary of the invention

[0038] The present invention will be further described below in conjunction with the accompanying drawings:

[0039] like Figures 1 to 3 As shown, an automated rolling production line includes a drying room 1. Four double-layered parallel conveyor lines 10 pass through the drying room 1. A plurality of carrier plates 12 are transported on the conveyor lines 10. A mold 11 is placed on the carrier plate 12. A lifting mechanism 3 is provided at one end of the conveyor line 10, and the lifting mechanism 3 is used for changing the layer of the carrier 12 between the conveyor lines 10 in the same row. The other end of the conveyor line 10 is connected to the turntable 5 through the transfer mechanism 4, and the transfer mechanism 4 is used for loading and unloading operations of the mold 11 of the turntable 5. A column changing mechanism 6 is provided between the conveyor lines 10 on the same layer at the connecting end, and the column changing mechanism 6 is used for changing the column of the carrier 12 between the conveyor lines 10 on the same layer. The mold 11 circulates on the conveyor line 10 and the turntable 5 with the cooperation of various mechanisms. The mold 11 on the turntable 5 is loaded by the mud extruder 8, and then rolled by the rolling machine 9. A mold opening and blank taking machine 2 is provided on the conveyor line 10 on the mold loading side of the turntable 5. A correction robot 7 is provided at the inlet end of the mold opening and blank taking machine 2, and the correction robot 7 is installed on the top of the lifting mechanism 3.

[0040] like Figures 4 to 8 As shown, the mold opening and blank taking machine 2 includes a frame 201, which is located between the drying room 1 and the lifting mechanism 3. The conveyor line 10 passes through the die-entering station of the frame 201. A blocker 202 is arranged in the die-entering station. The blocking arm of the blocker 202 can resist the carrier plate 12 after being ejected, playing the role of limiting the position of the mold 11. After the mold 11 is limited, the fixed cylinder output end pressure plates on both sides of the conveyor line 10 can press the outer mold of the mold 11 against the carrier plate. A vertical moving device 203 is arranged above the die-entering station (see Figure 5), the device is used to clamp out the inner mold in the blocked mold 11 upward. The track seat of the vertical moving device 203 is vertically installed between the beam rods of the frame 201. The top plate of the track seat is provided with a lifting motor. The threaded output shaft of the lifting motor is rotatably connected to the bottom plate of the track seat. The threaded output shaft is threadedly connected to the slider on the back side of the carriage. The slider is slidably connected to the track seat. The bottom of the carriage is connected to the cylinder body of the double-push cylinder. The push rods on both sides of the double-push cylinder are connected to the clamping jaws. During operation, the lifting motor drives the carriage to move downward from the middle position to the low position. Subsequently, the double-push cylinder tightens the clamping jaws. After clamping the inner mold, the carriage resets to the middle position.

[0041] In this embodiment, after the inner mold is clamped out by the vertical moving device 203, it is taken over by the translation device 204 (see Figure 6 ), and is translated to the blank taking station. The track beam of the translation device 204 is horizontally arranged between the beam rods of the frame 201 and is located below the vertical moving device 203. One end of the track beam is provided with a translation motor. The sprocket at the output end of the translation motor is connected to the sprocket seat through a drag chain. The sprocket seat is installed at the other end of the track beam. One side of the drag chain is connected to the I-shaped frame. The I-shaped frame is slidably connected to the track beam. The bottom surface of the protruding part on the same side of the I-shaped frame is connected to a pair of opening and closing cylinders. The opening and closing cylinders are connected to the cylinder body of the clamping cylinder. The push rods on the upper and lower sides of the clamping cylinder are connected to the clamping jaws. During operation, the I-shaped frame is located at the mold feeding station. After the inner mold is clamped out by the vertical moving device 203, the clamping cylinder tightens the clamping jaws to clamp the inner mold (the clamping directions between the two devices are perpendicular and do not interfere with each other). Subsequently, the vertical moving device 203 releases the inner mold and moves upward to the high position. The translation motor drives the I-shaped frame to slide to the blank taking station.

[0042] In this embodiment, a blank taking device 205 is provided above the blank taking station (see Figure 7), when the inner mold is moved to the blank taking station by the translation device 204, the blank taking device 205 can take out the blank in the inner mold, and translate the blank to the blank unloading station, and unload it onto the output belt 206 with variable distance. The two track beams of the blank taking device 205 are horizontally erected between the beams of the frame 201 and are located above the vertical movement device 203. A translation motor is provided at one end of the track beam on one side. The sprocket at the output end of the translation motor is connected to the sprocket seat through a drag chain. The sprocket seat is installed at the other end of the track beam on this side. A chain on one side of the drag chain is connected to the translation seat. The translation seat is slidably connected to the two track beams. A vertical rail seat is installed on one side of the translation seat. A lifting motor is provided on the top plate of the vertical rail seat. The threaded output rod of the lifting motor is rotatably connected to the bottom plate of the vertical rail seat. The threaded output rod is threadedly connected to the slider of the vertical movement plate. The slider is slidably connected to the vertical rail seat. One end of two pairs of swing arms are symmetrically hinged above the vertical movement plate. The swing arm body is connected to the output end of the variable pitch cylinder. The variable pitch cylinder body is installed below the vertical movement plate. The other end of the swing arm is hinged to the mounting arm. The bottom of the mounting arm is connected to a blank suction tube. The body of the blank suction tube is provided with an anti-deflection sponge, which cooperates with the opening of the blank. During operation, the translation seat is located at the blank taking station. After the inner mold is translated to the bottom by the translation device 204, the lifting motor drives the vertical moving plate downward, and the blank suction tube extends into the opening of the inner mold to adsorb the blank. Then the opening and closing cylinder in the translation device 204 pries the inner mold to both sides, and the vertical moving plate moves upward to drive the blank to separate from the inner mold. Then the translation motor drives the translation seat to the blank unloading station, the vertical moving plate moves downward, and the variable pitch cylinder pulls the swing arms on both sides together, and then the blank is placed on the output belt 206.

[0043] In this embodiment, a mold brushing device 207 (see Figure 8 ), the mold brushing device 207 can extend into the inner mold that is broken apart by the translation device 204 for cleaning. The lifting cylinder body of the mold brushing device 207 is vertically installed between the beams of the frame 201, and the output end of the lifting cylinder is connected to the transmission plate upward. The top surface of the transmission plate is provided with two bearing seats, and the bearing seats are rotatably connected to the rod bodies of two brush rods. The bottom end of one of the brush rods is connected to the output end of the cleaning motor, and the cleaning motor is installed on the bottom surface of the transmission plate. The rod body of the brush rod is provided with a pulley, and the two brush rods are driven by a belt connected by the pulley. When working, the lifting cylinder pushes the transmission plate upward, the brush rod extends into the broken apart inner mold, and the cleaning motor drives the two brush rods to rotate to clean the inner mold.

[0044] like Figures 9 to 10As shown, the deviation correction robot 7 includes a cantilever 701, the tail end of the cantilever 701 is installed on the top of the lifting mechanism 3, the head end of the cantilever 701 is vertically connected to the base plate 702, the base plate 702 is installed with a carrier of a lifting device 703, the top surface of the carrier is connected to the cylinder body of the lifting cylinder, the output end of the lifting cylinder is threadedly connected to the push rod, the upper end of the push rod is in contact with the bottom surface of the top plate of the lifting seat 704, the carrier is located in the vertical hole in the middle of the back plate of the lifting seat 704, the sliders on both sides of the back plate are slidably connected to the vertical rails on the base plate 702, and the bottom plate of the lifting seat 704 is connected to the rotating seat An articulated seat 705 is arranged, and the articulated seat is rotatably connected to the turntable in the middle of the seat plate. A correction motor is arranged on one side of the articulated seat, and the gear at the output end of the correction motor is meshed with the turntable gear ring. The bottom surface of the seat plate is connected to the double-push cylinder body in the clamping device 706, and the push rods on both sides of the double-push cylinder are connected to the clamping claws. A positioning sensor 707 is arranged on one side of the seat plate, and the positioning sensor 707 probe can identify the color mark groove of the inner mold of the clamped mold 11 (the inner mold is composed of two half molds, and the outer side of the half mold ring body is provided with a color mark groove, and the connecting line of the color mark grooves on both sides is perpendicular to and centered with the mold seam line). During operation, the mold 11 is transported to the bottom of the clamping device 706 and stops. The lifting cylinder is retracted to make the push rod move downward, and the lifting seat 704 moves downward by its own weight until it contacts the push rod again. At this time, the mold 11 is located between the clamping claws on both sides, and the correcting motor is started to drive the seat plate to rotate. The probe of the positioning sensor 707 searches for the position of the color mark slot during the rotation process, and stops rotating immediately after finding it. The double-push cylinder retracts the clamping claws to clamp the outer mold, and the lifting seat 704 moves upward, driving the mold 11 to separate from the conveyor line 10 belt surface. The correcting motor is started to drive the mold 11 to rotate in the opposite direction to the target position (that is, it can cooperate with the translation device 204 to pry open the inner mold), and then the lifting seat 704 moves downward to release the corrected mold 11.

[0045] like Figure 11 As shown, the lifting mechanism 3 includes a parallel frame 301, which is divided into two parallel lifting stations and cooperates with two rows of conveyor lines 10. The lifting station has a built-in lifting device 302. The lifting motor of the lifting device 302 is installed on one side of the bottom of the lifting station. The lifting motor drives the transmission shaft, which is rotatably connected to the two sides of the lifting station. The sprocket of the transmission shaft is connected to the sprocket seat through a drag chain. The sprocket seat is installed on the top of the lifting station. The chain on one side of the drag chain is connected to the slider of the roller table 303, and the sliders on both sides are slidably connected to the vertical rails 304 on both sides of the lifting station. The electric roller of the roller table 303 can rotate in the opposite direction. When the roller table 303 is located at the upper and lower dead points, the top of the electric roller can be flush with the belt surface of the upper and lower conveyor lines 10.

[0046] like Figures 13 to 15As shown in the figure, the transfer mechanism 4 includes a frame body 401. An up-and-down device 402 is arranged inside the top frame of the frame body 401. The vertical plate of the up-and-down device 402 is installed on the top cross beam of the frame body 401. An elevating motor is installed at the upper end of the vertical plate. The output end of the elevating motor is a lead screw. The lead screw is rotationally connected to a bearing seat installed at the lower end of the vertical plate. The lead screw is threadedly connected to a slider on the back of the elevating plate. The elevating plate is slidably connected to vertical rails on both sides of the vertical plate. The front of the elevating plate is connected to a lifting seat 403. The bottom plate of the lifting seat 403 is rotationally connected to a hinge seat in the middle of a swing arm 404. A swing motor 405 is installed on one side of the bottom plate. The gear at the output end of the swing motor 405 meshes with the toothed ring of the hinge seat. Both ends of the swing arm 404 are connected to the cylinder bodies of double-push cylinders of a clamping plate device 406. Push rods on both sides of the double-push cylinders are connected to clamping plates. During operation (see Figure 15 ), the swing motor 405 drives the swing arm 404 to rotate around the hinge seat. At this time, one clamping plate device 406 is directly above the mold 11 on the mold-inlet side conveyor line 10, and the other clamping plate device 406 is directly above the mold 11 at the unloading station of the turntable 5. The elevating motor is started to lower the lifting seat 403. The double-push cylinders of the clamping plate devices 406 on both sides contract the clamping plates to clamp the corresponding molds. Subsequently, the lifting seat 403 moves upward, and the swing arm 404 rotates around the hinge seat in the reverse direction to a symmetrical position. At this time, one clamping plate device 406 is directly above the loading station of the turntable 5, and the other clamping plate device 406 is directly above the mold-unloading side conveyor line 10. The lifting seat 403 is lowered to release the mold 11, assisting the turntable 5 to complete the mold loading and unloading operations simultaneously.

[0047] As Figure 12 shown in the figure, the column-changing mechanism 6 includes a base 601. The base 601 is installed at the bottom of the conveying arms of two parallel conveyor lines 10. A jacking motor in a cam jacking device 602 is installed on the top surface of the base 601. The jacking motor is drivingly connected to a camshaft. The camshaft is rotationally connected to the base 601. A vertical rod on the top surface of the base 601 is slidably connected to a sleeve at the bottom of a lifting frame seat 603. The bottom surface of the lifting frame seat 603 is in contact with a cam on the body of the camshaft. Three roller belts 604 with a transmission direction perpendicular to the conveyor line 10 are arranged on the top surface of the lifting frame seat 603. The gaps between the roller belts 604 are matched with the conveying arms. When the lifting frame seat 603 descends to the lowest point along with the cam, the roller belts 604 are flush with the belt surface of the conveyor line 10. At this time, the carrier plate 12 is transferred from the conveyor line 10 to the roller belts 604. When the lifting frame seat 603 rises to the highest point along with the cam, the belt surface of the roller belts 604 is higher than the conveyor line 10. At this time, the carrier plate 12 can be conveyed to the parallel conveyor line 10 along with the roller belts 604.

[0048] As Figure 16As shown in the figure, the turntable of the turntable 5 rotates clockwise under the drive of the stepping motor. Six evenly distributed loading holes 501 are provided around the top surface of the turntable. The loading holes 501 can load the mold 11. When one of the loading holes 501 rotates to the mold loading station and cooperates with the side conveyor line 10, another loading hole 501 rotates to the mold unloading station and cooperates with the opposite side conveyor line 10; when the loading hole 501 rotates to the feeding station and the rolling station, the mold 11 in the loading hole cooperates with the mud extruder 8 and the rolling press 9 respectively.

[0049] As Figures 16 to 18 shown, the rolling press 9 includes a base 901. A box body 902 is slidably connected to the top surface slide rail of the base 901. A cam lifting device 903 is arranged inside the box body 902. The cam lifting device 903 includes a camshaft driven by a motor. The cam on the camshaft body contacts the bottom surface of the support block of the lifting table 904. The lifting table 904 is slidably connected to the side surface of the box body 902. A mold rotating motor 905 is arranged on one side of the lifting table 904. The mold rotating motor 905 is drivingly connected to the built-in rotating shaft of the lifting table 904. The top of the rotating shaft is connected to a sleeve 906. When the lifting table 904 rises, the sleeve 906 can be sleeved into the mold 11 located directly above, and the mold 11 is driven to rotate by the mold rotating motor 905. A flat pushing device 907 is arranged on the top of the box body 902. One end of the slide rail of the flat pushing device 907 is provided with a driving motor. The output screw rod of the driving motor is rotatably connected to the other end of the slide rail. The screw rod body is threadedly connected to the bottom slider of the lifting arm 908. Both sides of the slider are slidably connected to the slide rail. The end surface of the arm seat of the lifting arm 908 is provided with a vertical rail. A lifting motor is installed at the top of the vertical rail. The output screw rod of the lifting motor is rotatably connected to the bottom of the vertical rail. The screw rod body is threadedly connected to the slide seat of the rolling device 909. The back of the slide seat is slidably connected to the vertical rail. The front of the slide seat clamps a roller box (the clamping angle can be adjusted). A roller head motor is arranged on one side of the roller box. The roller head motor is drivingly connected to the roller shaft in the roller box. The bottom end of the roller shaft is provided with a roller head.

[0050] As Figures 19 to 20 shown, the mud extruder 8 includes a base frame 801. A mud strip conveyor belt 802 is arranged on one side of the base frame 801. The mud strip on the top of the mud strip conveyor belt 802 is pushed into the mud inlet of the mud extrusion device 804 by the push plate of the mud pushing cylinder 803. The mud extrusion device 804 is installed on the top of the base frame 801 and includes three parts: a spiral pusher, a vacuum chamber and a mud extrusion cylinder. After the mud strip is pushed in, it is kneaded and cut into pieces by the spiral blade and enters the vacuum chamber. After being evacuated by the vacuum chamber, it is extruded from the mud extrusion cylinder. A mud feeding device 805 is arranged at the outlet of the mud extrusion cylinder (see Figure 20 ).

[0051] In this embodiment, the bracket of the mud feeding device 805 is installed on the top surface of the base frame 801. A mud cutting cylinder is provided on the top cross beam of the bracket. The output end of the mud cutting cylinder is connected to a mud cutting knife, which is slidably connected to the vertical rails on the columns on both sides of the cross beam. The extending arms on both sides of the bracket are hinged with the mud strip sensor supports at the arm bodies. The two supports can be uniformly adjusted in angle through a connecting rod. The head end of the extending arm is hinged with the body of a swing shaft. A mud feeding cylinder is provided in the middle of the swing shaft. The output end of the mud feeding cylinder is connected to a suction cup. The two ends of the swing shaft are hinged with linkage arms, and the other end of the linkage arm is hinged with the piston rod of a swing cylinder. The cylinder body of the swing cylinder is hinged with the bracket. During operation, the empty mold 11 rotates with the turntable 5 to stop at the feeding station. The swing cylinder contracts, and the suction cup faces inward to adsorb the mud extruded from the mud extrusion barrel. The mud cutting cylinder pushes the mud cutting knife downward to cut off the mud. Then the swing cylinder extends, and the suction cup flips 90 degrees to face vertically downward. The mud feeding cylinder is started to press the mud adsorbed by the suction cup into the opening of the mold 11, completing the feeding.

[0052] The working principle of the present invention is as follows:

[0053] As Figure 2 shown, when the carrier plate 12 carrying the empty mold 11 is conveyed by the upper conveyor line 10 to the upper roller belt 604, the transfer mechanism 4 loads the empty mold 11 onto the mold loading station of the turntable 5. Subsequently, the mold 11 rotates clockwise with the turntable 5 to the feeding station. The mud extrusion machine 8 feeds mud into the opening of the mold 11. After feeding, the mold 11 continues to rotate to the rolling station. The lifting table 904 rises, and the sleeve 906 is sleeved into the mold 11 and drives it to rotate. The rotating roller head in the rolling device 909 descends into the mold 11 to roll the mud. After rolling and forming, the mold 11 rotates to the mold unloading station. At the same time, the roller belt 604 is lifted by the cam to convey the carrier plate 12 to the opposite conveyor line 10. Subsequently, the transfer mechanism 4 clamps the mold 11 at the mold unloading station and unloads it onto the carrier plate 12. During the mold unloading process, the transfer mechanism 4 simultaneously loads the next empty mold 11 onto the mold loading station (the principle is shown in Figure 15 ).

[0054] After the mold 11 is unloaded, it enters the drying oven 1 with the opposite conveyor line 10 to perform the first drying on the green body. Subsequently, the mold 11 continues to be conveyed to the front of the lifting mechanism 3. The roller table 303 in the lifting station on this side of the lifting mechanism 3 is at the upper dead center position. At this time, the rotating direction of the electric roller in the roller table 303 is the same as that of the upper conveyor line 10. The carrier plate 12 is conveyed onto the roller table 303, and the roller table 303 descends to the lower dead center position. The electric roller is reversed to make the carrier plate 12 enter the lower conveyor line 10 on this side. The conveying direction of the lower conveyor line 10 is opposite to that of the upper conveyor line (see Figure 3) The carrier plate 12 carries the mold 11 into the drying oven 1 for the second drying. Subsequently, the carrier plate 12 is conveyed onto the lower roller belt 604. The roller belt 604 is lifted by the cam, and the carrier plate 12 is conveyed onto the opposite roller belt 604. The roller belt 604 resets to the low point, and the carrier plate 12 enters the opposite lower conveying line 10 and enters the drying oven 1 again with the conveying line 10 to perform the third drying on the green body. Subsequently, the carrier plate 12 enters the upper conveying line 10 on this side through the lifting mechanism 3 and stops under the clamping device 706 under the obstruction of the elastic arm position resistance inside the conveying line 10. The alignment manipulator 7 rotates and aligns the mold 11 so that the orientation of the inner mold clamping line can cooperate with each device in the mold opening and blank taking machine 2. Two molds 11 after alignment take out the inner mold in the mold opening and blank taking machine 2 in a group. The green body in the inner mold is unloaded onto the output belt 206 and conveyed out of the production line. The inner mold after blank taking is cleaned by the mold brushing device 207 and then reinstalled into the outer mold. The mold 11 after unloading enters the drying oven 1 for the fourth drying with the conveying line 10. The dried empty mold 11 returns to the upper roller belt 604 to prepare for the next cycle.

[0055] This production line can fully automatically produce various ceramic products by the rolling forming method. It adopts a double-layer parallel circulation structure, can dry the mold 11 four times through one cycle, meets the intermittent drying requirement, improves the production efficiency, and has the characteristics of compact structure and small floor area.

[0056] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
