Description

Technical Field

[0001] The invention relates to the technical field of gold foil beating equipment, in particular to a full-automatic gold foil beating machine. Background Art

[0002] The gold foil production process generally includes twelve steps: gold mixing, melting gold bars, beating leaves, making twists, dropping gold into the foil, dipping the twists, beating the foil, installing the foil, heating the pit, beating the foil, producing, and cutting the gold foil. During the beating and beating steps, workers must repeatedly beat the gold foil paper package left and right, front and back, in a specific beating sequence. Through this repetitive, mechanical action, the thickness of the gold foil in the package gradually decreases, facilitating the subsequent normal production of gold foil.

[0003] During the gold-cutting and gold-making processes, whether it is mechanical hammering or manual hammering, workers are required to manually adjust the position of the black gold paper package so that the black gold paper package can be hammered along the correct hammering route, making the gold foil produced of better quality.

[0004] Taking Da Le Xi as an example, in the traditional Da Le Xi process, referring to the existing article "Comparative Study on the Protection and Revitalization of Gold Foil Crafts in China and Japan" published by Nanjing University of Information Science and Technology in 2020, it can be seen that the order of beating the black gold paper bag is to gradually beat from the two outer paths to the two inner paths, and then gradually beat from the two inner paths to the center, and then beat to the head. After turning the black gold paper bag over, beat it from the two outer paths to the two inner paths again, and then follow the above-mentioned beating method and order. After the beating of both sides of the black gold paper bag is completed, turn the black gold paper bag 90 degrees and continue the above operation until the beating of the entire black gold paper bag is completed.

[0005] However, during the pounding process of the black gold paper bag, it is easy for the inexperienced master to move the black gold paper bag to the wrong position, which in turn leads to the wrong position of beating the black gold paper bag, causing the gold foil to be torn or broken in the end. Summary of the Invention

[0006] The invention provides a fully automatic gold foil hammering machine to solve the problem of easy occurrence of wrong hammering position when hammering black gold paper packages in the existing gold foil production process, thereby preventing the produced gold foil from being torn or broken.

[0007] A fully automatic gold foil hammering machine of the present invention adopts the following technical solutions: A fully automatic gold foil hammering machine comprises a frame, a support plate, a support block, a matching plate, a clamping frame, a moving mechanism and a turning mechanism, wherein a striking device is provided on the frame; the support plate is rotatably arranged on the frame and is located below a hammering rod of the striking device; the support block is arranged on the support plate; two matching plates are provided, both of which are arranged on the support plate and are symmetrical about the support block; the clamping frame is arranged between the two matching plates and between the support block and the hammering rod of the striking device, and is used for clamping a black gold paper bag; the moving mechanism is used for controlling the clamping frame to move in a length direction parallel to the matching plates and to control the clamping frame to move in a width direction parallel to the matching plates, and the turning mechanism is used for flipping the clamping frame.

[0008] Furthermore, the moving mechanism includes a mating block, a driving cylinder and a fixed shaft, the mating block is slidably arranged on the mating plate, the driving cylinder is installed at one end of the mating plate, and its output shaft is fixedly connected to the mating block, the fixed shaft is arranged on the side opposite to the clamping frame and the mating plate, and the end of the fixed shaft away from the clamping frame passes through the mating plate on the corresponding side and is passed through the mating block on the mating plate; the moving mechanism also includes a transmission control component, which is used to control the fixed shaft to move along its axial direction.

[0009] Furthermore, the flipping mechanism includes a flip wheel and a matching column. The flip wheel is located on one side of the matching plate. The flip wheel is rotatably arranged on the matching block and sleeved on the fixed shaft. The flip wheel is slidably connected with the fixed shaft and rotates synchronously. The matching column is fixed on the matching plate. There are two matching columns. The two matching columns are located on the diagonal line of one side of the matching plate and are centrally symmetrically distributed about the center of the matching plate. A flip angle is provided on the flip wheel, which has a flat bottom surface and a side curved surface. The flat bottom surface and the side curved surface form an end angle. When the end angle moves along the length direction of the mating plate, the flat bottom surface is located on the outside of the mating column, and the notch of the side curved surface faces the mating column on the side of its moving direction.

[0010] Furthermore, the mating plate is provided with two limiting rods, which are respectively located outside the two mating columns. The two limiting rods are located on the diagonal line on the other side of the mating plate and are centrally symmetrically distributed about the center of the mating plate. The limiting rods are parallel to the length direction of the mating plate. When the flip wheel translates along the length direction of the matching plate, the flat bottom surface of the flip angle abuts against the limiting rod.

[0011] Furthermore, there is a gap between the matching column and the limiting rod.

[0012] Furthermore, a straight groove is provided on the flat bottom surface of the flip angle, and one end of the straight groove away from the end angle of the flip angle passes through the flip wheel. A limit strip is slidingly arranged in the straight groove, and the bottom side surface of the limit strip is flush with the flat bottom surface. One end of the limit strip away from the end angle of the flip angle extends out of the straight groove, and the other end is fixedly connected to a groove wall on one side of the straight groove close to the end angle of the flip angle by a spring.

[0014] Furthermore, a cavity is provided on the matching block through which the reciprocating screw passes, a positioning shaft is rotatably provided on the cavity wall, and the shuttle is arranged on the positioning shaft.

[0015] Furthermore, a reversing assembly is provided in the intersection area of ​​the two spiral grooves of the reciprocating screw, and the reversing assembly is configured to change the moving path of the shuttle in the spiral groove.

[0016] Furthermore, the reversing assembly includes a stopper, a limiting assembly, and a tension spring. The stopper is configured to extend and retract within the spiral groove of the reciprocating screw. The tension spring is configured to return the stopper extending from the bottom of the spiral groove to the bottom of the spiral groove. The limiting assembly is used to make the upper portion of the stopper protrude from the bottom of the spiral groove. The shuttle comprises an upper end piece and a lower end piece, the upper end piece is hinged on the positioning shaft through a torsion spring, and the lower end piece is fixed to the bottom end of the positioning shaft, and the upper end piece and the lower end piece are in opposite directions; When the shuttle moves relatively to the stopper in the spiral groove of the reciprocating screw, the upper end piece is configured to change the moving path of the shuttle, and the lower end piece is configured to release the restriction of the stopper on the spiral groove by the limit assembly.

[0017] The beneficial effects of the present invention are: The invention relates to a fully automatic gold foil beating machine. The black gold foil paper bag is fastened in a clamping frame, and then a moving mechanism drives the clamping frame to move between matching plates toward one end of the matching plates. When the clamping frame moves, a beating rod of a beating device can repeatedly beat the black gold foil paper bag in the clamping frame, and as the clamping frame moves, the beating rod of the beating device can repeatedly beat different positions of the black gold foil paper bag. When the clamping frame moves outside the beating area of ​​the beating device, a turning mechanism drives the clamping frame and the black gold foil paper bag to turn over. The turned-over clamping frame and the black gold foil paper bag are driven by the moving mechanism to move toward the other side of the matching plate. During the movement, the beating rod of the beating device beats the newly turned-over side of the black gold foil paper bag, thereby beating both the front and back sides of the black gold foil paper bag, so that the gold twist in the black gold foil paper bag is beaten more evenly. In addition, the support plate in the present invention is rotatably arranged on the frame. After beating the front and back sides of the black gold paper bag, the support plate is rotated 90 degrees, so that the positions of the black gold paper bag and the beating rod can be changed. Then, the rotated black gold paper bag is beaten again, so that the black gold paper bag is beaten in different directions, and the black gold paper bag can be beaten more thoroughly. After the black gold paper bag is rotated twice or more and the beating is completed, the black gold paper bag is beaten in at least four directions, so that the thickness of the gold twist in the black gold paper bag can be beaten thinner and more uniformly. The present invention is a moving mechanism that drives the clamping frame to move, a turning mechanism that drives the clamping frame to flip, and a motor that drives the support disk to rotate. All of the moving mechanism drives the clamping frame to move, the turning mechanism drives the clamping frame to flip, and the motor drives the support disk to rotate. When beating a black gold paper bag, it is only necessary to fasten the black gold paper bag in the clamping frame and adjust the position of the black gold paper bag corresponding to the hammer rod of the beating device. Then, the moving mechanism can automatically drive the clamping frame to move, the turning mechanism can automatically flip the clamping frame that has moved beyond the range of the hammer rod, and the support disk can automatically rotate the black gold paper bag. When the black gold paper bag passes under the hammer rod of the beating device, the beating device can automatically beat the black gold paper bag. During the whole process, there is no need to manually move and flip the black gold paper bag, which greatly reduces the possibility of the black gold paper bag being placed incorrectly, greatly improves the safety during gold foil production, and reduces the workload of workers.

[0018] Furthermore, the flipping wheel is mounted on the fixed shaft. When the flipping wheel rotates, it can drive the fixed shaft to rotate. At the same time, the fixed shaft can be slidably arranged on the flipping wheel. After the clamping frame is flipped, the fixed shaft can be pushed to move in its axial direction through a pushing structure such as an electric cylinder, so that the corresponding positions of the black gold paper bag and the hammering rod of the striking device are changed, which facilitates more comprehensive hammering of the black gold paper bag.

[0019] Furthermore, when the flip wheel moves, it can drive the reciprocating screw to move synchronously. When the flip wheel rotates, the flip wheel can drive the fixed axis away from the reciprocating screw to rotate, and then drive the reciprocating screw to rotate through the clamping frame. When the reciprocating screw rotates, since the position of the shuttle on the matching block remains unchanged, the reciprocating screw can only move along its axial direction when rotating, so that the striking device can not only hammer the black gold paper bag in the direction parallel to the movement of the flip wheel, but also hammer the black gold paper bag in the direction parallel to the axial direction of the reciprocating screw, so that the area where the striking device hammers the black gold paper bag is more comprehensive, and the quality of the gold foil produced is better.

[0020] Furthermore, during the rotation of the reciprocating screw, when the shuttle moves to the stopper in the reversing assembly, the stopper can push the shuttle to rotate into another spiral groove of the opposite rotation direction, so that the movement direction of the reciprocating screw is changed, and the beating device can again beat the area of ​​the black gold paper bag that has not been directly beaten, so that the black gold paper bag is beaten more evenly and the quality of the gold foil produced is better. In addition, the reversing component provided can realize the automatic hammering of the black gold paper bag of the present invention. It is only necessary to fasten the black gold paper bag in the clamping frame, and the subsequent hammering, turning and movement of the black gold paper bag can be completed independently by the present invention, which can realize the automatic hammering of the black gold paper bag, not only avoiding the need for manual movement and turning of the black gold paper bag in the beating process, but also greatly reducing the workload of workers in making gold foil, and can improve the production efficiency of gold foil.

[0027] like Figures 1 to 16 As shown, a fully automatic gold leaf hammering machine comprises a frame 100, a support plate 101, a support block 200, a matching plate 300, a clamping frame 400, a moving mechanism 500 and a tilting mechanism 600. The frame 100 is provided with a striking device 110, which can include a hammer rod 111 vertically arranged on the frame 100, a crank connecting rod mechanism connected to the hammer rod 111 and capable of driving the hammer rod 111 to move up and down repeatedly in its axial direction, and a belt driving mechanism that drives the crank connecting rod mechanism. Driven by the belt driving mechanism, the hammer rod 111 can do reciprocating motion in the vertical direction through the crank connecting rod mechanism.

[0028] The support disc 101 is mounted horizontally on the frame 100 and is located below the hammer rod 111 of the striking device 110. The support disc 101 is rotated by a motor mounted on the frame 100. The motor may be a servo motor to facilitate control of the speed and number of revolutions. The support disc 101 may be a geared disc, with a gear meshing with the geared disc mounted on the output shaft of the motor. When the motor is running, the rotation of the support disc 101 can be controlled.

[0029] The support block 200 can be a square block. The support block 200 is mounted on the support plate 101 and is also located below the hammer rod 111 of the striking device 110. Two matching plates 300 are provided. Both matching plates 300 are fixed on the support plate 101. Both matching plates 300 are rectangular plates. The two matching plates 300 are symmetrically arranged on the support plate 101 about the support block 200. The clamping frame 400 is arranged between the two matching plates 300 and is located between the hammer rod 111 of the striking device 110 and the support block 200. The clamping frame 400 can be a rectangular frame formed by four rods and capable of varying the area of ​​the frame opening. The clamping frame 400 is used to clamp the black gold paper bag with the gold twister built in. The thickness of the black gold paper bag is greater than the height of the clamping frame 400. When the black gold paper bag is tightened by the clamping frame 400, the bottom surface of the black gold paper bag conflicts with the top surface of the support block 200. When the size of the black gold paper bag is determined, the positions of the various rods on the clamping frame 400 can be changed. When the four rods form a frame opening whose area is adapted to the size of the black gold paper bag, the black gold paper bag is placed in the frame opening and the clamping frame 400 is fastened by fasteners such as bolts, so that the clamping frame 400 can fasten the black gold paper bag.

[0030] The moving mechanism 500 and the turning mechanism 600 are both arranged on the frame 100 and are both automatic mechanisms. The moving mechanism 500 can automatically drive the clamping frame 400 to move in a length direction parallel to the matching plate 300 and in a width direction parallel to the matching plate 300, thereby changing the position of the black gold paper bag relative to the hammer rod 111 of the striking device 110, so that the striking device 110 can hammer different positions of the black gold paper bag. The turning mechanism 600 can automatically flip the clamping frame 400, thereby turning the black gold paper bag over, so that the hammer rod 111 of the striking device 110 can hammer both sides of the black gold paper bag when hammering the black gold paper bag. In conjunction with the moving mechanism 500 that can move the black gold paper bag (clamping frame 400) on the frame 100, the upper and lower sides of the black gold paper bag can be hammered more evenly.

[0031] After the front and back sides of the black gold paper bag are hammered, the motor can automatically drive the support plate 101 to rotate 90 degrees, so that the orientation of the black gold paper bag changes. Repeating the above hammering process can complete the hammering of the black gold paper bag in another orientation. Then, the support plate 101 is rotated twice, which completes the comprehensive hammering of the black gold paper bag in four orientations, so that the thickness of the final gold foil produced can be more uniform and thinner.

[0032] The operating principle of the present invention is: First, the black gold paper bag is fastened in the clamping frame 400, and then the clamping frame 400 is driven by the moving mechanism 500 to move between the two matching plates 300 toward one end of the matching plate 300. During the movement of the clamping frame 400, the hammer rod 111 of the striking device 110 can repeatedly hammer the black gold paper bag in the clamping frame 400. Since the clamping frame 400 moves toward one end of the matching plate 300, the hammer rod 111 of the striking device 110 can hammer the black gold paper bag in a direction parallel to the length of the matching plate 300. Afterwards, the clamping frame 400 is driven by the moving mechanism 500 to move between the two matching plates 300 along the width direction of the matching plates 300, and the hammering rod of the hammering device 110 can hammer the black gold paper bag parallel to the width direction of the matching plates 300, thereby achieving comprehensive hammering of the black gold paper bag; When the hammering rod 111 of the striking device 110 hammers the outside of the black gold paper bag, the clamping frame 400 and the black gold paper bag are turned over by the turning mechanism 600, and then the clamping frame 400 is driven to continue to move in two directions by the moving mechanism 500. During the movement of the clamping frame 400, the hammering rod 111 hammers the turned-over black gold paper bag again, so that both the front and back sides of the black gold paper bag are hammered.

[0033] After beating the front and back sides of the black gold paper bag, the black gold paper bag can be driven by the support plate 101 to rotate 90 degrees so that the black gold paper bag is in a new orientation, and then the beating process is repeated to complete the beating of the new orientation of the black gold paper bag; After the support plate 101 rotates repeatedly several times, the black gold paper bag can be hammered in at least four directions, thereby achieving comprehensive hammering of the black gold paper bag in multiple directions, so that the final hammered gold foil can be thinner and more uniform in thickness.

[0034] In the present invention, the moving mechanism 500 that drives the clamping frame 400 to move, the turning mechanism 600 that drives the clamping frame 400 to flip, and the motor that drives the support plate 101 to rotate are all automatic mechanisms. When beating the black gold paper bag, it is only necessary to fasten the black gold paper bag in the clamping frame 400 and adjust the position of the black gold paper bag corresponding to the hammer rod 111 of the beating device 110. Then the moving mechanism 500 can automatically drive the clamping frame 400 to move, and the turning mechanism 600 can automatically move to the range of the hammer rod 111. The clamping frame 400 outside the punching device 110 is turned over, and when the black gold paper bag passes below the punching rod 111 of the punching device 110, the punching rod 111 of the punching device 110 can automatically punch the black gold paper bag. After the above operation is completed, the support plate 101 can automatically rotate 90 degrees under the drive of the motor, so that the punching rod 111 of the punching device 110 can punch the black gold paper bag again. After repeatedly rotating the support plate 101 for many times, the punching device 110 can punch the black gold paper bag in all directions. The whole process does not require manual movement, flipping and rotation of the black gold paper bag, which greatly reduces the possibility of the black gold paper bag being placed incorrectly, greatly improves the safety of the gold foil production, and reduces the workload of the workers.

[0035] In some embodiments, the moving mechanism 500 includes a mating block 510, a drive cylinder 520, and a fixed shaft 530. The mating plate 300 is provided with a sliding hole 301 parallel to its length. The mating block 510 is inserted into the sliding hole 301 and can be slidably mounted on the mating plate 300 along the length of the sliding hole 301. The mating block 510 can be a rectangular block with a square cross-section, and a through-hole is formed at the end of the mating block 510. When the mating block 510 is inserted into the sliding hole 301, its upper and lower surfaces respectively contact the upper and lower walls of the sliding hole 301. The axial direction of the fixed shaft 530 is perpendicular to the length of the mating plate 300. Two fixed shafts 530 are provided, and the two fixed shafts 530 are fixed to the two corresponding side surfaces of the clamping frame 400 and the two mating plates 300. The end of the fixed shaft 530 facing away from the clamping frame 400 is inserted into the through-hole of the mating block 510 on the corresponding mating plate 300.

[0036] A restraining mechanism is provided between the mating block 510 and the corresponding mating plate 300 to limit the sliding movement of the mating block 510. This restraining mechanism may be a combination of restraining shafts fixed to the upper and lower walls of the sliding hole 301 and sliding grooves formed on the upper and lower surfaces of the mating block 510. The restraining mechanism constrains the mating block 510 to move within the sliding hole 301 and only along the length of the sliding hole 301.

[0037] When the mating block 510 moves in the sliding hole 301, the clamping frame 400 can move between the support block 200 and the hammer rod 111 of the striking device 110 along the length direction parallel to the sliding hole 301, and the hammer rod 111 of the striking device can hammer the black gold paper bag passing below it and clamped by the clamping frame 400.

[0038] A drive cylinder 520 is mounted on one end of the mating plate 300, and its output shaft is fixedly connected to the mating block 510. The drive cylinder 520 can be a hydraulic cylinder or an electric cylinder, and its output shaft can propel the mating block 510 to move. When the drive cylinder 520 propels the mating block 510 to move, it can gradually propel the mating block 510 at a fixed speed or at equal time intervals. This, in turn, can propel the clamping frame 400 via the fixed shaft 530, allowing the hammer rod 111 of the striking device 110 to more evenly strike different locations of the black gold paper bag, resulting in a more effective hammering effect on the black gold paper bag and further facilitating the production of gold foil.

[0039] The moving mechanism 500 further includes a transmission control assembly, which is used to control the fixed shaft 530 to move along its axial direction, that is, to control the fixed shaft 530 to move along a width direction parallel to the mating plate 300 .

[0040] The transmission control assembly can be a driving member capable of pushing the fixed shaft 530 in its axial direction. The driving member can be an electric cylinder mounted on the mating block 510, parallel to the axis of the fixed shaft 530. A bearing is mounted on the portion of the fixed shaft 530 extending from the mating block 510. A bearing holder is fixed to the output end of the electric cylinder, and the bearing is mounted on the bearing holder. Specifically, a bearing holder is fixed to the end of the output shaft of the electric cylinder, and a bearing is fixed to the bearing holder. The portion of the fixed shaft 530 extending from the mating block 510 passes through the inner hole of the bearing and is fixedly connected to the inner hole wall. When the output shaft of the electric cylinder is extended or retracted, it can drive the fixed shaft 530 to move synchronously through the bearing, and when the fixed shaft 530 rotates, the fixed shaft 530 can rotate within the bearing.

[0041] When the present invention is provided with a pusher, the clamping frame 400 can be moved in a direction parallel to the width of the mating plate 300, and any position on the black gold paper bag can be moved below the hammer rod 111 of the striking device 110, which means that the striking device 110 can hammer the black gold paper bag in all directions. In this case, the striking device 110 is no longer limited to hammering the black gold paper bag in a straight line, but can also hammer the black gold paper bag in a staggered manner.

[0042] When the hammering rod 111 of the hammering device 110 is aimed at the second area of ​​the black gold paper bag, the hammering device 110 can gradually hammer the second area of ​​the black gold paper bag, and when the second area of ​​the black gold paper bag is hammered to the center, the clamping frame 400 is turned over by the turning mechanism 600, and then the fixed shaft 530 is pushed in the opposite direction by the pushing member to hammer the black gold paper bag again, so that the hammered area of ​​the black gold paper bag is hammered from the center to the top, thereby completing the hammering of the black gold paper bag by the hammering device 110.

[0043] Furthermore, the flipping mechanism 600 includes a flipping wheel 610 and a mating post 620. The flipping wheel 610 is located on the side of the mating plate 300 facing the clamping frame 400. The flipping wheel 610 is rotatably connected to the end of the mating block 510 facing the clamping frame 400 via a bearing. The flipping wheel 610 is sleeved on the fixed shaft 530 so that the fixed shaft 530 can be slidably connected to the flipping wheel 610 along its axial direction.

[0044] A limiting groove is provided on the inner hole wall of the flip wheel 610, and a limiting slide bar adapted to the limiting groove is fixed on the side of the fixed shaft 530. When the fixed shaft 530 is passed through the flip wheel 610, the limiting slide bar passes through the limiting groove adapted to it, so that when the flip wheel 610 rotates, it can drive the fixed shaft 530 to rotate synchronously.

[0045] Two mating posts 620 are provided, both fixed to the mating plate 300 and axially perpendicular to the mating plate 300. Both mating posts 620 are located on a diagonal line on one side of the mating plate 300, one on either side of the center of the mating plate 300, and are symmetrically distributed about the center of the mating plate 300.

[0046] The flip wheel 610 is provided with a flip angle having a flat bottom surface 631 and a side curved surface 632. The flat bottom surface 631 and the side curved surface 632 form an end angle. The side curved surface 632 is a smooth, concave surface. When the end angle moves along the length of the mating plate, the flat bottom surface 631 is located outside the mating column 620, and the notch of the side curved surface 632 faces the mating column 620 on the side of its movement direction.

[0047] As the flip wheel 610 moves along the sliding hole 301 with the fixed shaft 530, the flip angle moves synchronously with the flip wheel 610. When the side curved surface 632 of the flip angle hits the matching column 620, the flip wheel 610 can rotate around the matching column 620 with the contact point between the side curved surface 632 and the matching column 620 as the starting point.

[0048] Rotating the flip wheel 610 drives the fixed shaft 530, which in turn drives the clamping frame 400. When the flip wheel 610 rotates 180 degrees, the black gold paper bag is flipped. After the black gold paper bag is flipped, the striking device 110 strikes the back of the black gold paper bag, facilitating even striking of the black gold paper bag and facilitating the production of gold foil.

[0049] Furthermore, two limiting rods 310 are provided on the mating plate 300. The length of the limiting rods 310 is parallel to the length of the mating plate 300. The two limiting rods 310 are respectively located near the upper and lower sides of the mating plate 300 and are located outside the two mating columns 620 on the mating plate 300. The two limiting rods 310 are located on the diagonal line on the other side of the mating plate 300 and are distributed symmetrically about the center of the mating plate 300.

[0050] The flip wheel 610 is located between the two limiting rods 310. When the flip wheel 610 translates on the mating plate 300, the flat bottom surface 631 of the flip angle abuts against one of the limiting rods 310. When the limiting rods 310 and the flat bottom surface 631 of the flip wheel 610 abut against each other, the flip wheel 610 can only translate along the limiting rods 310, preventing the flip wheel 610 from rotating during translation along the limiting rods 310.

[0051] In this embodiment, the limiting rod 310 limits the translation of the flip wheel 610, preventing the flip wheel 610 from rotating at will, making it difficult for the black gold paper bag clamped by the clamping frame 400 to rotate at will, so that the hammer rod 111 of the striking device 110 can hammer the black gold paper bag in a direction parallel to the limiting rod 310 without deflection.

[0052] Furthermore, a gap is left between the engagement post 620 and the limiting rod 310. As the flip wheel 610 moves along the limiting rod 310, its flip angle can enter the gap between the engagement post 620 and the limiting rod 310. When the side curved surface 632 of the flip angle abuts the engagement post 620, the engagement post 620 exerts a certain counter-thrust force on the flip wheel 610, thereby causing the flip wheel 610 to rotate. As the flip wheel 610 rotates, its flip angle can rotate within the gap between the limiting rod 310 and the engagement post 620, allowing the flip wheel 610 to complete its flipping on the engagement plate 300.

[0053] During the flipping process of the flipping wheel 610, the flat bottom surface 631 of the flipping angle, which is away from the end angle, is the first to break away from the limiting rod 310 on which it is located and to contact the other limiting rod 310. As the flipping wheel 610 continues to flip, the flat bottom surface 631 of the flipping angle can completely contact the other limiting rod 310, thereby completing the flipping of the flipping wheel 610. When the flipping wheel 610 flips, it drives the fixed shaft 530 to rotate synchronously, thereby driving the clamping frame 400 and the black gold paper bag within the clamping frame 400 to rotate synchronously, thereby turning the black gold paper bag. This allows the striking device 110 to strike both sides of the black gold paper bag, making the black gold paper bag more evenly struck and reducing the possibility of gold foil breaking due to uneven striking.

[0054] Furthermore, a straight groove 611 is provided on the flat bottom surface 631 of the flip angle, and the end of the straight groove 611 away from the flip angle extends through the flip wheel 610. A limiting bar 612 is slidably provided in the straight groove 611 and is parallel to its length direction, and the bottom side surface of the limiting bar 612 is flush with the flat bottom surface 631. A spring is connected to the end of the limiting bar 612 near the flip angle, and the spring is fixedly connected between the limiting bar 612 and the groove wall of the straight groove 611 near the flip angle. The end of the limiting bar 612 away from the flip angle extends out of the straight groove 611, and the limiting bar 612 is configured to prevent the flip wheel 610 from rotating arbitrarily on the mating plate 300.

[0055] When the flip wheel 610 slides between the limit rods 310, the length direction of the limit bar 612 is parallel to the length direction of the limit rod 310 and can fit with the limit rod 310; when the flip angle of the flip wheel 610 is against the matching column 620 and rotates around the matching column 620, the limit bar 612 first separates from the limit rod 310 and first contacts the other limit rod 310; when the limit bar 612 contacts the other limit rod 310, the flip wheel 610 is still rotating around the matching column 620, so the other limit rod 310 can apply a certain pressure on the limit bar 612, which can cause the limit bar 612 to compress the spring and gradually retract into the straight slot 611; when the flip wheel 610 completes flipping, the limit bar 612 can fit with the other limit rod 310 and will re-extend into the straight slot 611 under the action of the restoring force of the spring.

[0056] Since the end of the limit bar 612 away from the flip angle extends out of the straight groove 611 and is flush with the flat bottom surface 631 of the flip angle, when the flip wheel 610 slides between the limit rods 310, the limit bar 612 can fit with the limit rods 310, thereby preventing the flip wheel 610 from rotating during movement. Only when the flip angle of the flip wheel 610 enters the gap between the limit rod 310 and the matching column 620 and rotates around the matching column 620, can the limit bar 612 rotate.

[0057] The limit strip 612 further restricts the flipping of the flip wheel 610, so that the flip wheel 610 can be flipped only under specific circumstances, thereby preventing the black gold paper bag from being unevenly hammered due to the random flipping of the flip wheel 610, and preventing the gold foil in the black gold paper bag from being torn or broken due to uneven hammering.

[0058] Of course, in some embodiments, the flip wheel 610 is also provided with a plurality of mating teeth evenly distributed along its outer wheel surface. Two groups of limiting columns are provided on the mating plate 300, and the number of limiting columns in each group is equal to the number of mating teeth. The two groups of limiting columns are respectively provided on the side away from each other of the two mating columns 620, and each group of limiting columns is evenly spaced on one side of the corresponding mating column 620. When the flip wheel 610 rotates 180 degrees, the flat bottom surface 631 of the flip wheel 610 fits with the limiting rod 310, and the plurality of mating teeth can just enter the gap between the plurality of limiting columns and the corresponding mating columns 620. The provision of the mating teeth, limiting columns and limiting rod 310 can prevent the flip wheel 610 from reversing or turning too far, which helps to improve the operational stability of the present invention.

[0059] In some embodiments, the transmission control assembly includes a reciprocating screw 532 and a shuttle 700. In the above-described embodiment, one of the fixed shafts 530 on either side of the clamping frame 400 is a reciprocating screw 532. The reciprocating screw 532 is provided with two helical grooves of equal pitch and opposite rotation, connected end to end by a transition curve. The shuttle 700 is mounted on a mating block 510 through which the reciprocating screw 532 passes. The shuttle 700 is positioned within and mates with the helical grooves of the reciprocating screw 532. When the reciprocating screw 532 rotates, the shuttle 700 can move within its helical groove along the axis of the reciprocating screw 532, similar to how an auger propels material. In this embodiment, when the flipping wheel 610 flips, it can drive the reciprocating screw 532 and the clamping frame 400 to flip. When the reciprocating screw 532 rotates, since the shuttle 700 is positioned on the matching block 510, and the matching block 510 cannot move, the reciprocating screw 532 can move in its axial direction, thereby causing the clamping frame 400 to move in the axial direction of the reciprocating screw 532. The position on the clamping frame 400 corresponding to the hammer rod 111 of the striking device 110 can be misaligned, thereby changing the position of the striking device 110 striking the black gold paper bag.

[0060] When the drive cylinder 520 that pushes the mating block 510 is activated, the clamping frame 400 of the present invention can automatically flip and dislocate, eliminating the need for workers to flip and dislocate the gold foil paper bag. This not only greatly reduces the workload of gold foil production, but also allows for safer hammering of the gold foil paper bag. Furthermore, the mechanical hammering method is more efficient than manual hammering, and the problem of misplacement of the gold foil paper bag can be avoided. This can prevent the gold foil from breaking or shattering due to misplacement of the gold foil paper bag during production.

[0061] Furthermore, the mating block 510, through which the reciprocating screw 532 passes, is provided with a cavity adapted for the reciprocating screw 532. The reciprocating screw 532 is disposed within the cavity and is capable of rotating about and sliding along its axial direction within the cavity. A positioning shaft 511 is rotatably connected to the cavity wall. The end of the positioning shaft 511, which is distal to the cavity wall, faces the bottom of the spiral groove of the reciprocating screw 532. The end of the positioning shaft 511, which is distal to the cavity wall, extends into the spiral groove of the reciprocating screw 532. The shuttle 700 is mounted on the positioning shaft 511.

[0062] When the flip wheel 610 rotates, the shuttle 700 remains stationary, while the clamping frame 400 drives the reciprocating screw 532 to rotate. This allows the shuttle 700 to move relative to the spiral groove of the reciprocating screw 532. The shuttle 700's movement within the spiral groove is aligned with the orientation of the shuttle 700. The reciprocating screw 532 rotates along the shuttle 700 and, as it does so, drives the clamping frame 400 to move axially, causing the hammer rod 111 of the striking device 110 to change position relative to the black gold paper bag, thereby achieving flipping and misalignment of the black gold paper bag. After the flip wheel 610 flips multiple times, when the shuttle 700 moves to the end of the spiral groove in the reciprocating screw 532, since the moving direction of the shuttle 700 relative to the spiral groove is consistent with the orientation of the shuttle 700, one end of the shuttle 700 will first rest against the end groove wall of the spiral groove, and then twist along the extension direction of the spiral groove, and then enter another reverse spiral groove.

[0063] Assuming that the shuttle 700 has not moved relative to the end of the spiral groove, the black gold paper bag can move in the first direction after each flip. When the shuttle 700 moves relative to the end of the spiral groove, at this time, when the black gold paper bag flips again, the shuttle 700 will move to another reverse spiral groove, and the black gold paper bag will also move in a second direction opposite to the first direction.

[0064] The dislocated movement of the black gold paper bag in the second direction enables the striking device 110 to strike the unstruck area of ​​the black gold paper bag, so that the striking device 110 strikes the black gold paper bag more evenly, and the final gold foil produced has a more uniform thickness and better quality.

[0065] Furthermore, a reversing assembly 800 is provided in the intersection area of ​​the two spiral grooves of the reciprocating screw 532 , and the reversing assembly 800 is configured to change the moving path of the shuttle 700 in the spiral groove.

[0066] The reversing assembly 800 can be a fixed block that can be detachably mounted in the intersection area of ​​the two spiral grooves of the reciprocating screw 532. The fixed block can serve as the end groove wall of the spiral groove in the intersection area of ​​the spiral groove. When the shuttle 700 moves into the intersection area, its upper end piece 710 can abut against the fixed block and reverse, so that the shuttle 700 slides relatively to the other reverse spiral groove.

[0067] The arrangement of the reversing assembly 800 enables the hammer rod 111 of the striking device 110 to strike only a certain area of ​​the black gold paper bag, facilitating the striking of a specific area of ​​the black gold paper bag. For example, it is possible to strike areas with a large number of protrusions or a thicker thickness, thereby making the gold foil more evenly struck. Alternatively, the black gold paper bag can be struck in sections, for example, the outer two sections, the inner two sections, the center, and the top of the black gold paper bag can be struck in sequence. During the striking process, only the position of the fixed block needs to be changed.

[0068] When the reversing assembly 800 is not provided, two or more groups of the present invention may be provided. Some of the present inventions may be used to specifically hit the outer two paths and the inner two paths, and some of the present inventions may be used to specifically hit from the center to the head. By using a plurality of groups of the present inventions to divide the work and cooperate with each other, the efficiency of gold foil production can be improved.

[0069] In some embodiments, the reversing assembly 800 includes a stopper 810, a limiting assembly 820, and a tension spring 830. The stopper 810 is configured to extend and retract within the spiral groove of the reciprocating screw 532. The tension spring 830 is configured to return the stopper 810, which has extended beyond the bottom of the spiral groove, to its lower portion. The limiting assembly 820 is configured to cause the upper portion of the stopper 810 to protrude beyond the bottom of the spiral groove. The shuttle 700 includes an upper end piece 710 and a lower end piece 720. The upper end piece 710 is hinged to the positioning shaft 511 via a torsion spring, while the lower end piece 720 is fixed to the bottom of the positioning shaft 511. The upper end piece 710 and the lower end piece 720 face in opposite directions.

[0070] When the shuttle 700 moves relative to the stop block 810 in the spiral groove of the reciprocating screw 532, the upper end piece 710 is configured to change the movement path of the shuttle 700, and the lower end piece 720 is configured to release the restriction of the stop block 810 on the spiral groove by the limit assembly 820.

[0071] Specifically, one end of the reciprocating screw 532 is provided with a reset groove 5321 and a clamping groove 5322 axially parallel to the reciprocating screw 532. The clamping groove 5322 is located between the reset groove 5321 and the outer side of the reciprocating screw 532. A pressing groove is provided at the intersection of the two spiral grooves of the reciprocating screw 532. The bottom of the pressing groove passes through the clamping groove 5322 and communicates with the reset groove 5321. The reversing assembly 800 is disposed in the pressing groove. The stopper 810 is inserted into the pressure groove, with one end of the stopper 810 extending deep into the pressure groove and into the reset groove 5321. The stopper assembly includes a spring slot 821 and an elastic clip 822. The spring slot 821 is located on the side of the stopper 810 facing the shuttle 700. The elastic clip 822 is tilted and disposed within the spring slot 821. The spring slot 821 communicates with the spiral groove of the reciprocating screw 532. One end of the elastic clip 822 extends out of the spring slot 821 and engages with the bottom of the spiral groove of the reciprocating screw 532. A tension spring 830 is located within the clamping groove 5322 and is connected between the stopper 810 and the wall of the clamping groove 5322.

[0072] The elastic clip 822 is fixed to the side wall of the spring slot 821 near the reset slot 5321. The end of the elastic clip 822 away from the reset slot 5321 can be a wedge-shaped block, which extends out of the notch of the spring slot 821 and hooks onto the bottom of the spiral groove. The spring slot 821 can also be provided with a spring to maintain the elastic clip 822's tilt. Under the action of the spring force, the elastic clip 822 can more tightly contact the bottom of the spiral groove.

[0073] The thickness of the upper end piece 710 is smaller than that of the lower end piece 720, and the upper end piece 710 is located above the lower end piece 720. Both the upper end piece 710 and the lower end piece 720 can be angular structural members, with the end angles of the upper end piece 710 and the lower end piece 720 facing opposite directions. When the shuttle 700 is located in the spiral groove of the reciprocating screw 532, the directions of the upper end piece 710 and the lower end piece 720 are adapted to the extension direction of the spiral groove on the corresponding side.

[0074] In the direction in which the shuttle 700 moves relative to the spiral groove, the upper end piece 710 of the shuttle 700 faces the stopper 810 on its front side. When the shuttle 700 moves to the intersection area of ​​the spiral groove where the stopper 810 is located, the upper end piece 710 of the shuttle 700 can abut against the stopper 810 and, under the pressure of the stopper 810, can twist and turn to the other opposite spiral groove, while the lower end piece 720 of the shuttle 700 gradually moves along the stopper 810 to the other opposite spiral groove.

[0075] As the lower end piece 720 of the shuttle 700 moves along the stopper 810, it pushes the wedge-shaped block at the end of the elastic card 822 into the shrapnel groove 821, causing the stopper 810 to disengage from the spiral groove. The stopper 810, now disconnected from the spiral groove, slides toward the reset groove 5321 under the tension of the tension spring 830, thereby completely disengaging from the spiral groove. After another reversal, when the shuttle 700 reaches this area again, the stopper 810 in this area no longer blocks the relative movement of the shuttle 700, allowing the shuttle 700 to move further relative to the reciprocating screw 532. This also means that the black gold paper bag can move further in the axial direction of the reciprocating screw 532, and the black gold paper bag can be struck by the striking device 110 over a wider range.

[0076] Two stoppers 810 can be provided in the spiral groove, and the two stoppers 810 are respectively arranged in different intersection areas on the spiral groove. When the striking device 110 is beating the black gold paper bag, the hammering rod 111 of the striking device 110 can be aligned with the outer two-way area of ​​the black gold paper bag, and the position of the shuttle 700 on the reciprocating screw 532 is defined to be located at the O point of the reciprocating screw 532. Two stoppers 810 are provided at the appropriate positions of the spiral groove of the reciprocating screw 532, and the two stoppers 810 are respectively located on both sides of the O point, wherein the point closer to the O point is defined as the P point, which corresponds to the head on the black gold paper bag, and the point farther from the O point is defined as the Q point, which corresponds to the heart on the black gold paper bag. When the present invention starts to operate, the shuttle 700 in the spiral groove moves toward point Q. When the shuttle 700 moves to point Q, the striking device 110 completes the beating of the outer two routes and the inner two routes of the black gold paper bag, and beats it to the center of the black gold paper bag; thereafter, the shuttle 700 changes its moving direction under the action of the stop block 810 at point Q, so that the shuttle 700 moves toward point P. When the shuttle 700 moves to point P, the striking device 110 beats the area between the center position and the top position (including the center and the top) of the black gold paper bag, thereby completing the beating process of the black gold paper bag.

[0077] The reversing assembly 800 provided by the present invention can realize automatic hammering of the black gold paper bag. The black gold paper bag only needs to be fastened in the clamping frame 400. The subsequent hammering, turning and movement of the black gold paper bag are all completed independently by the present invention, which can realize automatic hammering of the black gold paper bag. It not only avoids the need for manual movement and turning of the black gold paper bag during the beating process, but also greatly reduces the workload of workers in making gold foil, and can improve the production efficiency of gold foil.

[0078] After the hammering of the black gold paper bag is complete, the reciprocating screw 532 can be removed from the mating block 510. A long rod with an inclined surface at its end can then be inserted into the reset groove 5321, with the inclined surface of the long rod facing the pressure groove. As the long rod moves within the reset groove 5321, the inclined surface at its end can push the stopper 810, which had been retracted into the pressure groove, back out of the pressure groove opening. As the stopper 810 extends out of the pressure groove opening, the elastic clip 822 within the shrapnel groove 821 also extends out of the shrapnel groove 821. One end of the elastic clip 822 can then reattach to the bottom of the spiral groove, thereby resetting the stopper 810 on the reciprocating screw 532 and facilitating the next use of the present invention.

[0079] The reciprocating screw 532 may be provided with multiple stoppers 810. When hammering gold foil bags of different sizes or other methods, the stoppers 810 on the reciprocating screw 532 can be adjusted manually or by tools, for example, by using a screwdriver to push the elastic clip 822 back into the shrapnel slot 821, so that the stoppers 810 on the reciprocating screw 532 meet the hammering requirements of the gold foil. When the stoppers 810 are located within the mating block 510, the reciprocating screw 532 can be unscrewed from the mating block 510 to readjust its position before adjusting the stoppers 810 again.

[0080] It should be noted that in the above embodiments, when the clamping frame 400 drives the black gold paper bag to rotate, the clamping frame 400 is located outside the support block 200. When the clamping frame 400 rotates, it is in a suspended state and cannot touch the support block 200.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
