Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping equipment, in particular to a metal bottle cap automatic stamping machine. BACKGROUND

[0002] The bottle cap of a beer bottle or the like is formed by stamping a metal plate through a stamping device. One side of the metal plate is printed with information such as a trademark and promotional text in advance.

[0003] At present, a common stamping device includes a stamping device and a feeding device. A conveying belt is arranged between the feeding device and the stamping device. The feeding device transports the metal plate to the conveying belt, and the conveying belt transports the metal plate to the stamping device. The feeding device includes a feeding table for stacking the metal plates and a mechanical arm capable of moving up and down and horizontally. An electromagnet is arranged at the bottom of the mechanical arm. During feeding, the mechanical arm first moves to a position above the metal plates and close to the conveying belt, then moves downward until the electromagnet contacts the metal plates, at which time the uppermost metal plate is attracted by the electromagnet. Then the mechanical arm moves upward to drive the metal plate to above the conveying belt, then moves horizontally to lower the metal plate to the conveying belt, and finally turns off the electromagnet to separate the metal plate from the electromagnet. At this time, the metal plate completely falls on the conveying belt under the action of gravity, and then the conveying belt starts to transport the metal plate to the stamping part to stamp the metal plate into a bottle cap.

[0004] The metal plate may pass through other processes before stamping, which may cause some impurities on the metal plate. During movement to the conveying belt, the metal plate may bend and deform due to its thin thickness and gravity, and the impurities at the bottom of the metal plate may fall off under the shaking action of the metal plate during movement. However, the impurities at the top of the metal plate can only slide along the bending direction of the metal plate, and the separation effect is poor, which may cause residues. The residues may be stamped together with the metal plate during stamping, which may cause the produced bottle cap to have a bulge or protrusion, affecting the quality of the bottle cap. SUMMARY

[0005] In order to reduce the number of impurities on the metal plate during stamping, the present application provides a metal bottle cap automatic stamping machine.

[0006] The present application provides a metal bottle cap automatic stamping machine, which adopts the following technical scheme:

[0054] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0055] This application discloses an automatic metal bottle cap stamping machine. See also... Figure 1, the automatic punch press comprises a punch press body 1 and a conveying part 2. The conveying part 2 is fixedly arranged on the feeding side of the punch press body 1, and comprises a mounting seat 21, a conveying belt 22 connected end to end and rotating in a loop, and a power motor 23 for driving the conveying belt 22 to move. The mounting seat 21 is fixed on the feeding side of the punch press body 1, the conveying belt 22 is arranged on the mounting seat 21, and the power motor 23 is fixed on the mounting seat 21. In operation, the metal plates are conveyed by the conveying belt 22 to the punch press body 1 on the top of the conveying belt 22, and finally punched by the punch press body 1 to form metal bottle caps.

[0056] The automatic punch press further comprises a feeding device arranged on the conveying part 2 away from the punch press body 1, and the metal plates to be punched are first stacked on the feeding device and then transmitted one by one to the conveying part 2 by the feeding device.

[0057] The feeding device comprises a bearing table 3, a mounting frame 4, a mechanical feeding arm 5, a cleaning roller 6 and a driving assembly. The bearing table 3 is fixed on the side of the mounting seat 21 away from the punch press body 1, and the top of the bearing table 3 is provided with a standby area 321. The metal plates to be punched are first stacked neatly and then hoisted by a hoisting device and stacked on the standby area 321. In other embodiments, the top of the bearing table 3 can also be fixed with a plurality of abutting columns by fixing bolts. The abutting columns are arranged around the standby area 321, and the top end surface of the abutting columns is in the same plane as the top end surface of the uppermost metal plate, so as to limit the position of the metal plates.

[0058] The mounting frame 4 is composed of a plurality of mounting columns, and the mounting frame 4 is fixed on the top corners of the bearing table 3. The mounting frame 4 is fixedly connected with a control part, the mechanical feeding arm 5 is arranged on the control part, the mechanical feeding arm 5 can move up and down and in the horizontal direction, and the bottom of the mechanical feeding arm 5 is fixedly connected with an electromagnet. In use, the control part controls the mechanical feeding arm 5 to move to the side close to the conveying part 2 of the metal plates to be punched, and then the control part controls the mechanical feeding arm 5 to extend downward, so that the electromagnet can attract the metal plates to be punched. Then the mechanical feeding arm 5 is retracted upward to drive the metal plates to move upward above the conveying part 2, and finally the control part controls the mechanical feeding arm 5 to move above the conveying part 2, and then the electromagnet is turned off to drop the metal plates, so that the metal plates can fall on the conveying belt 22 and be conveyed to the punch press body 1 by the conveying belt 22. Since the specific structure of the mechanical feeding arm 5 is prior art, it will not be described here.

[0059] Referring to Figure 2 and Figure 3 The cleaning roller 6 slides above the standby area 321, and the central axis direction of the cleaning roller 6 is parallel to the conveying part 2 (the conveying part 2 is arranged on the feeding side of the punch press body 1). Figure 1The direction of the metal plate conveyed is perpendicular to the direction of the cleaning roller 6. The outer periphery of the cleaning roller 6 is uniformly fixed with a plurality of cleaning bristles 61. When the cleaning roller 6 moves close to or away from the conveying part 2 in the horizontal plane, the cleaning bristles 61 are in contact with the uppermost metal plate, and at this time, the cleaning bristles 61 drive the impurities adhered to the surface of the metal plate into a movable state, which is beneficial to the separation of the impurities from the metal plate.

[0060] Referring to Figure 1 With Figure 3 , the driving assembly is arranged on the mounting frame 4. When the mechanical feeding arm 5 moves downward to adsorb the metal plate, the driving assembly drives the cleaning roller 6 to move away from the stamping machine body 1 until the cleaning roller 6 is separated from the metal plate. At this time, the cleaning bristles 61 clean the surface of the metal plate, so that the impurities on the surface of the metal plate are driven into a movable state and separated from the metal plate, thereby reducing the number of impurities on the metal plate. When the mechanical feeding arm 5 adsorbs and drives the metal plate to move upward, the driving assembly drives the cleaning roller 6 to move close to the stamping machine body 1, so that the cleaning bristles 61 clean the surface of the next adjacent metal plate. Therefore, the adjacent metal plate after the first metal plate can be cleaned twice by the cleaning bristles 61, which greatly reduces the possibility of impurities on the metal plate.

[0061] Referring to Figure 2 With Figure 4 , the driving assembly includes a driving plate 7, a driving column 71, a transmission column 72, a return spring 73, a return torsion spring 74, a guide column 75, and a connecting column 76.

[0062] Referring to Figure 1 With Figure 3 , the guide column 75 has two groups and is symmetrically arranged. Each group of guide columns 75 has two guide columns 75 arranged symmetrically above and below. The guide column 75 is perpendicular to and fixedly connected to the mounting column and located above the stacked metal plates. The length direction of the guide column 75 is perpendicular to the central axis of the cleaning roller 6, and the two guide columns 75 in the same group have a gap therebetween. The connecting column 76 has two connecting columns 76 fixedly arranged at the two ends of the cleaning roller 6, and the connecting column 76 is coaxially arranged between the cleaning rollers 6. Each connecting column 76 corresponds to a group of guide columns 75, and each connecting column 76 slides between the two guide columns 75 in the same group. The connecting column 76 slides along the length direction of the guide column 75 to guide the sliding direction of the cleaning roller 6, so that the cleaning roller 6 can move close to or away from the conveying part 2 in the horizontal plane.

[0063] Referring to Figure 1 With Figure 2, drive column 71 has two and symmetrically arranged, two drive column 71 is located adjacent to the two mounting column of the transmission part 2, drive column 71 with the mounting column parallel. Drive column 71 side wall fixedly connected with the slider of "T" shape structure, the mounting column is provided with "T" shape structure of the sliding groove extending along the vertical direction, the slider slides up and down in the sliding groove, so that the drive column 71 slides up and down along the vertical direction. Reset spring 73 is installed in the sliding groove, the top of reset spring 73 abuts the bottom of the slider, the bottom of reset spring 73 abuts the bottom groove wall of the sliding groove. In the initial state, the mechanical feeding arm 5 is located above the conveying belt 22, at this time, the reset spring 73 is elastically released, the slider is pushed to slide up to abut the top groove wall of the sliding groove, so that the drive column 71 is located adjacent to the top end surface of the conveying belt 22.

[0064] Referring to Figure 4 , drive plate 7 and drive column 71 one to one correspondence and fixed on the two sides of the mechanical feeding arm 5, the mechanical feeding arm 5 is located on the side away from the transmission part 2 (the transmission part 2 is marked in Figure 1 ), the drive plate 7 is rectangular plate structure, the drive plate 7 extends to the direction of the transmission part 2. When the mechanical feeding arm 5 moves to between the two mechanical feeding arms 5, the drive plate 7 is located directly above the drive column 71, at this time, the mechanical feeding arm 5 moves downward, then the drive plate 7 abuts the top of the drive column 71, and then drives the drive column 71 to move downward.

[0065] Referring to Figure 4 and Figure 5 , the two drive columns 71 are respectively fixedly connected with the rotating shafts, the transmission column 72 is connected to the rotating shafts, the reset torsional spring 74 is sleeved on the outer circumferential side of the rotating shaft, one end of the reset torsional spring 74 abuts the transmission column 72, and the other end abuts the drive column 71. The transmission column 72 is rotatably connected with the connecting column 76 on the side away from the drive column 71. In the initial state, the reset torsional spring 74 is elastically released, the drive transmission column 72 is turned over to the direction of the drive column 71, drives the cleaning roller 6 to move to the direction of the transmission part 2, and the cleaning roller 6 is away from the top of the metal plate, at this time, the transmission column 72 and the drive column 71 have a certain angle.

[0066] When the drive column 71 moves downward, the drive column 71 drives the transmission column 72 to turn over to the direction away from the drive column 71, at this time, the cleaning roller 6 moves away from the transmission part 2, the angle between the transmission column 72 and the drive column 71 gradually increases, and the reset torsional spring 74 is in the elastic compression state; until the transmission column 72 is turned over to be parallel to the metal plate, the cleaning roller 6 moves away from the metal plate in the direction away from the transmission part 2.

[0067] Referring to Figure 3In order to further improve the effect of the cleaning roller 6 on cleaning the impurities on the top of the metal plate, the opposite sides of the two guide columns 75 in the same group are respectively provided with accommodating grooves 752, the upper guide column 75 is fixedly connected with a driving rack 751, and the driving rack 751 is located in the accommodating groove 752. The outer circumferential side of the connecting column 76 is fixedly connected with a driving gear 761, the driving gear 761 protrudes into the accommodating groove 752, and the driving gear 761 is engaged with the driving rack 751.

[0068] Referring to Figure 1 With Figure 3 When the cleaning roller 6 moves away from the stamping machine body 1, the driving rack 751 drives the cleaning roller 6 to rotate through the driving gear 761, so that the cleaning brush 61 sweeps the impurities on the top of the metal plate away from the stamping machine body 1. When the upper adjacent metal plate is driven by the mechanical feeding arm 5 to be conveyed to the conveying belt 22, the metal plate is in a moving state, and the residual impurities slide downward along the bending direction of the metal plate to the top of the lower adjacent metal plate; when the cleaning roller 6 moves towards the stamping machine body 1, the cleaning roller 6 rotates, so that the cleaning brush 61 drives the impurities on the top of the metal plate to be in a moving state at the same time, and the impurities are cleaned towards the stamping machine body 1, so that the top of the metal plate is in a moving state and the residual impurities of the previous adjacent metal plate are separated from the metal plate.

[0069] Referring to Figure 2 With Figure 4 The driving column 71 comprises an inner column 711, an outer column 712 and a connecting spring 713; the transmission column 72 is connected to the bottom of the outer column 712, the top of the outer column 712 is provided with a connecting groove extending in the vertical direction, the inner column 711 slides up and down in the connecting groove, and the connecting spring 713 is installed in the connecting groove, the top of the connecting spring 713 abuts against the inner column 711, and the top of the connecting spring 713 abuts against the groove wall at the bottom of the connecting groove. In use, the connecting spring 713 is elastically released to push the inner column 711 to protrude out of the connecting groove. When the driving plate 7 moves downward, it first abuts against the top of the inner column 711, and then the driving plate 7 drives the inner column 711 to slide downward at the same time, and transmits power through the connecting spring 713 to push the outer column 712 to slide downward, so that the transmission column 72 flips away from the outer column 712. When the mechanical feeding arm 5 drives the metal plate to move upward, the connecting spring 713 first releases part of the elastic force, so that the inner column 711 slides upward, at this time the transmission column 72 temporarily flips to be close to the outer column 712, so that there is a certain time difference between the movement of the cleaning roller 6 and the metal plate driven by the mechanical feeding arm 5, which is beneficial to the cleaning brush 61 to clean the impurities of the previous adjacent metal plate remaining on the next adjacent metal plate.

[0070] Referring to Figure 1 With Figure 3, with the mechanical feeding arm 5 constantly moving the metal plates to the conveying part 2, the thickness of the stacked metal plates is constantly reduced, in order to enable the cleaning brush 61 to clean the uppermost metal plate, the carrying table 3 comprises a table body 31, a carrying plate 32 and a control assembly 33; the table body 31 is fixed on the side of the mounting seat 21 away from the stamping machine body 1, the top end face of the table body 31 is in a rectangular structure, and the length direction of the table body 31 extends away from the conveying part 2. The carrying plate 32 slides up and down on the top of the table body 31, and the carrying plate 32 is in a rectangular plate structure, the end face area of the carrying plate 32 is smaller than that of the top end face of the table body 31, and the length direction of the carrying plate 32 is parallel to that of the table body 31.

[0071] Referring to Figure 5 With Figure 6 The control assembly 33 comprises control columns 331 and control springs 332, the control columns 331 are arranged on the bottom of the carrying plate 32, and a plurality of control columns 331 are symmetrically arranged on the bottom of the carrying plate 32. The top of the table body 31 is provided with control grooves 311 corresponding to the control columns 331, the control columns 331 slide up and down in the control grooves 311, and the diameter of the control grooves 311 is greater than that of the control columns 331. The control springs 332 correspond to the control columns 331 and are sleeved on the outer circumferential side of the control columns 331, the top of the control spring 332 abuts against the bottom of the carrying plate 32, and the bottom of the control spring 332 abuts against the top of the table body 31. The top of the carrying plate 32 is provided with a material area 321, and the metal plates to be stamped are stacked in the carrying area, at this time, the control spring 332 is elastically released, and the carrying plate 32 is supported. When the number of metal plates to be stamped in the material area 321 decreases, the downward force generated by the carrying plate 32 decreases, at this time, the control spring 332 pushes the carrying plate 32 upward to move upward, so that the upper and lower heights of the uppermost metal plate to be stamped are substantially the same.

[0072] In order to reduce the case that the pressure between the metal plate and the cleaning brush 61 is too large, the control column 331 is rotationally connected with the bearing plate 32, and two groups of support teeth 312 are symmetrically fixed on the side wall of the control groove 311, and each group of support teeth 312 has a plurality of support teeth 312 and is uniformly arranged up and down. The outer periphery of the control column 331 is symmetrically provided with two sliding teeth 3311 which are engaged with the support teeth 312. When the control column 331 moves upward, the sliding teeth 3311 slide on the support teeth 312, and when the control column 331 slides downward, the support teeth 312 unidirectionally support the sliding teeth 3311. When the number of metal plates is continuously reduced, the control spring 332 exerts an upward force on the bearing plate 32, and the sliding teeth 3311 first abut against the support teeth 312, until the number of metal plates is reduced to a certain extent, the control spring 332 drives the bearing plate 32 to move upward, at this time the sliding teeth 3311 slide to the next adjacent support teeth 312, so that the uppermost metal plate is close to the cleaning roller 6, and the distance between the metal plate and the cleaning roller 6 is kept, and the cleaning brush 61 cleans the metal plate while reducing the pressure of the metal plate pressing the cleaning brush 61 too large to cause the cleaning brush 61 to break.

[0074] During processing, the mechanical feeding arm 5 moves to a position above the metal plate and close to the conveying part 2, and then the mechanical feeding arm 5 moves downward to adsorb the metal plate. During the downward movement of the mechanical feeding arm 5, the driving column 71 moves downward, at this time the transmission column 72 turns away from the driving column 71, drives the cleaning roller 6 away from the punching machine body 1, so that the cleaning brush 61 cleans the top of the metal plate. Then the mechanical feeding arm 5 drives the metal plate to the conveying part 2, at this time the driving column 71 moves upward, the cleaning roller 6 moves toward the punching machine body 1, the cleaning brush 61 cleans the next adjacent metal plate, finally the mechanical feeding arm 5 drives the metal plate to move to the conveying part 2, the transmission part drives the metal plate to move to the punching machine body 1, so that the punching machine body 1 punches the metal plate to generate a bottle cap.
