[0061] The present invention is further described in detail below in conjunction with the embodiments. It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like herein indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown in the coordinate system is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0062] like Figure 1 As shown, this embodiment proposes a fully automatic embossing and milling machine, which integrates a feeding part 1, an upper guide rail 2, an embossing part 4, a lower guide rail 5, a milling part 6 and a feeding part 7 in sequence according to the processing route of the bottle cap. At the same time, in this solution, the embossing part 4 and the milling part 6 are driven by the same integrated power unit 3. This can reduce the size of the equipment, reduce the floor space of the factory, and reduce costs.

[0063] like Figures 2 to 4As shown, the loading part 1 includes a frame, on which a hopper 101, a vibration plate 102 and a cap sorting part 103 are fixedly mounted, wherein the hopper 101 is located at the top, and workers can pour unprocessed bottle caps into the hopper 101, and the vibration plate 102 is installed directly below the hopper 101, for receiving the bottle caps output from the hopper 101. The cap sorting part 103 includes a cap sorting plate 1031, a cap sorting part housing 1032 and a cap sorting driving part 1033 (i.e., a motor) for driving the cap sorting plate 1031 to rotate, the cap sorting plate 1031 is disc-shaped, and a plurality of bottle cap receiving notches 501 are opened in the circumferential direction, the side of the cap sorting part housing 1032 is provided with an input port and an output port, and the bottom surface is provided with an air blowing port 1034 for blowing air into the bottle cap receiving notches 501. The output end of the vibration plate 102 is connected to the input port of the cover sorting part shell 1032 , and the output port of the cover sorting plate 1031 shell is connected to the upper guide track 2 .

[0064] In the feeding part 1, the operation process of the bottle caps is as follows: the bottle caps enter the vibration plate 102 from the hopper 101, and are output to the cap sorting plate 1031 through the vibration plate 102. Due to its unique structural design, the cap sorting plate 1031 can only allow the bottle caps with openings facing upward or downward to enter the bottle cap receiving gap 501. The cap sorting plate 1031 rotates, and under the action of centrifugal force, the bottle caps are sent out of the output port and into the upper guide track 2. The design of the blowing port 1034 can make the bottle caps with openings facing downward be blown out of the bottle cap receiving gap 501, thereby ensuring that the bottle caps output from the cap sorting part 103 are all neatly opened upward, thereby ensuring the accurate position of the embossed and milled characters on the bottle caps.

[0065] like Figure 1 As shown, the two ends of the upper guide track 2 are respectively connected to the cap discharging port and the convex part 4, and there is a section in the middle designed to be twisted by 90 degrees, which can twist the bottle caps from vertical to horizontal and output them.

[0066] Before describing the embossing part 4 and the milling part 6, the integrated power part 3 is described first. Figures 17 to 20 As shown, the integrated power unit 3 includes a base plate, on which a driving sprocket 301, an integrated power source (i.e., a motor) 302 for driving the driving sprocket 301, two power shafts 303 and two clutches 304 are provided. The power shafts 303 are connected with driven sprockets 305 via bearings, and one of the power shafts 303 is fixed with a convex character part power sprocket 306, which is used to input power to the convex character part 4, and the other power shaft 303 is fixed with a milling character part power sprocket 307, which is used to input power to the milling character part 6. The driving sprocket 301 and the driven sprocket 305 are driven by a chain, and the driven sprocket 305 and the power shaft 303 are connected by a clutch 304 to realize power transmission and separation.

[0067] Preferably, the clutch 304 comprises a lever 3041, a horizontal moving lever 3042, a shift fork 3043, a spring seat 3044, a tension spring 3045 and a sleeve 3046. The sleeve 3046 is slidably connected to the power shaft 303 through a spline and is arranged opposite to the driven sprocket 305. The sleeve 3046 is provided with a tooth 1 3047 on the surface facing the driven sprocket 305, and the driven sprocket 305 is provided with a tooth 2 3048 that can engage with the tooth 1 3047 on the surface facing the sleeve 3046. The horizontal moving lever 3042 is arranged parallel to the power shaft 303 (refer to Figure 1 The shifting rod 3041 is rotatably connected to the bottom plate and is used to control the horizontal moving rod 3042 to move forward or backward along the X direction. The two ends of the shifting fork 3043 are respectively fixed on the shaft sleeve 3046 and the horizontal moving rod 3042. When the shifting rod 3041 controls the horizontal moving rod 3042 to move forward or backward along the X direction, the shaft sleeve 3046 can slide axially on the power rotating shaft 303 through the shifting fork 3043, thereby realizing the engagement or separation of the tooth 1 3047 and the tooth 2 3048. When tooth one 3047 is engaged with tooth two 3048, the power output by the integrated power source 302 reaches the power shaft 303 via the driving sprocket 301, the driven sprocket 305 and the shaft sleeve 3046, and is then output via the power shaft 303 and the convex / milled power sprocket 306 / 307; when tooth one 3047 is separated from tooth two 3048, the power output by the integrated power source 302 reaches the driven sprocket 305 via the driving sprocket 301. Since the driven sprocket 305 and the power shaft 303 are connected by a bearing, the driven sprocket 305 is idling at this time.

[0068] like Fig.19 and Fig. 20 As shown, the two power shafts 303 correspond to the power output of the embossing part 4 and the milling part 6 respectively, and a clutch 304 is provided on each power shaft 303. The power input of the embossing part 4 and the milling part 6 can be controlled by adjusting the respective clutches 304. When the power shaft 303 does not input power, it is in a manual control state, that is, the embossing part 4 or the milling part 6 is manually driven.

[0069] In order to ensure that the first tooth 3047 and the second tooth 3048 can be tightly engaged during power transmission, a spring seat 3044 is installed on the power shaft 303. The spring seat 3044 is located on the side of the sleeve 3046 away from the driven sprocket 305, and the two ends of the tension spring 3045 are pressed between the spring seat 3044 and the sleeve 3046. The spring force presses the first tooth 3047 and the second tooth 3048. Preferably, a tensioning mechanism 308 is also provided between the driving sprocket 301 and the driven sprocket 305 to adjust the tension of the chain.

[0070] like Figures 5 to 7As shown, the embossing part 4 includes an embossing spindle 401, a mold unit 403, an embossing ejecting unit 404 and an embossing feeding unit 405 located between the mold unit 403 and the embossing ejecting unit 404; the embossing spindle 401 passes through the mold unit 403, the embossing feeding unit 405 and the embossing ejecting unit 404, and a embossing sprocket 402 is fixed on the embossing spindle 401, and the embossing sprocket 402 is connected to the embossing part power sprocket 306 through a chain, so as to transmit power to the embossing spindle 401, and transmit power to the mold unit 403, the embossing feeding unit 405 and the embossing ejecting unit 404 respectively through the embossing spindle 401.

[0071] The mold unit 403 includes a die shaft 4031 and a punch shaft 4032 which are parallel to the embossing main shaft 401; an embossing mold gear 4033 is fixed to the embossing main shaft 401; a die 4034 and a die gear 4035 meshing with the embossing mold gear 4033 are fixed to the die shaft 4031; a punch 4036 and a punch gear 4037 meshing with the die gear 4035 are fixed to the punch shaft 4032; the punch 4036 and the die 4034 can cooperate with each other to realize the embossing operation of the bottle cap.

A guide track groove 4045 is provided on the side wall of the embossed material ejection transmission shaft 4043. The embossed material ejection mechanism includes an embossed material ejection slider 4046 slidably connected to the side wall of the embossed material ejection box 4041, and an embossed character ejection rod 4048 and an embossed character follower wheel 4047 matched with the guide track groove 4045 are installed on the embossed character ejection slider 4046. The embossed character ejection rod 4048 is coaxially arranged with the punch 4036. The power reaches the convex character ejection drive shaft 4043 from the convex character main shaft 401, the convex character ejection driving gear 4042, and the convex character ejection transmission gear 4044, so that the guide rail groove 4045 rotates, and the convex character follower wheel 4047, under the guidance of the guide rail groove 4045, drives the end of the convex character ejection rod 4048 to approach or move away from the punch 4036 through the convex character ejection slider 4046. The convex mold 4036 is covered with a convex character stripping ring 4049, and the convex character stripping ring 4049 and the convex character ejection slider 4046 are fixed by a connecting rod.

When the embossed character feeding cam 4052 rotates, it contacts the embossed character feeding bearing 4053 on one side, causing the embossed character feeding slider 4051 to slide to the other side. The sliding direction of the embossed feeding slider 4051 is perpendicular to the sliding direction of the embossed ejecting slider 4046. The embossed feeding slider 4051 is provided with a embossed feeding tongue plate. The embossed feeding tongue plate is provided with adjacent embossed grooves 1 4054 and embossed grooves 2 4055. The embossed groove 1 4054 is located between the embossed feeding slider 4051 and the embossed grooves 2 4055. The embossed groove 1 4054 is used to receive the bottle caps dropped from the upper guide track 2, and the embossed grooves 2 4055 are used to receive the bottle caps withdrawn from the punch 4036.

[0074] refer to Figure 23a to Figure 23h , the operation process of the embossing part 4 is as follows (the three bottle caps involved in the process description are defined as the first bottle cap, the second bottle cap and the third bottle cap respectively):

[0075] S1. Fig.23a , the convex groove 4054 moves to below the output end of the upper guide track 2, and the upper guide track 2 outputs the first bottle cap to the convex groove 4054;

[0076] S2. Figure 23b and Fig.23c , the convex groove 4054 moves between the punch 4036 and the convex push rod 4048, the convex push slider 4046 pushes the convex push rod 4048 to push the first bottle cap on the convex groove 4054 into the punch 4036, and the convex stripping ring 4049 moves from the head of the punch 4036 to the root of the punch 4036;

[0077] S3. Fig.23d , the embossing feeding slider 4051 moves the embossing groove 2 4055 to between the punch 4036 and the embossing push rod 4048, and at the same time the punch 4036 cooperates with the concave mold 4034 to complete the embossing operation, at which time the embossing groove 1 4054 returns to the bottom of the upper guide track 2 to receive the second bottle cap output by the upper guide track;

[0078] S4. Fig.23e , the convex push slider 4046 pulls back the convex push rod 4048, and at this time the convex withdrawal ring 4049 is synchronously pulled back to the head of the punch 4036, so that the first bottle cap on the punch 4036 is withdrawn to the convex groove 4055;

[0079] S5. Figure 23f, the convex character feeding slider 4051 feeds the convex character groove 2 4055 carrying the first bottle cap into the lower guide track 5, and at the same time feeds the convex character groove 1 4054 carrying the second bottle cap to between the punch 4036 and the convex character ejector rod 4048;

[0080] S6. Figure 23g , the convex push rod 4048 pushes the second bottle cap into the punch 4036;

[0081] S7. Figure 23h The convex feeding slider 4051 drives the convex groove 2 4055 to return. During the return process, since the convex push rod 4048 has not returned to its position, the first bottle cap on the convex groove 2 4055 hits the convex push rod 4048, rolls out of the convex groove 2 4055 and enters the lower guide track 5. When the convex groove 1 4054 moves to the bottom of the upper guide track 2, the third bottle cap output by the upper guide track is output to the convex groove 1 4054.

[0082] Through the above cycle, the embossing process of the bottle cap and the input and output of the embossing part 4 are realized. In the above process, the mold unit 403, the embossing ejecting unit 404 and the embossing feeding unit 405 are all driven by an embossing spindle 401, and the transmission structure has a very high integration degree and a high degree of automation, which further reduces the size of the equipment, reduces the cost compared to the solution of multiple power sources, and also ensures production efficiency.

[0083] The two ends of the lower guide rail 5 are respectively connected to the convex part 4 and the milling part 6. Fig.10 As shown, a notch 501 with a width smaller than that of the bottle cap is provided on the bottom surface of the lower guide track 5. When the bottle cap passes through the notch 501, if the bottle cap is not positioned correctly, its lateral width is smaller than the width of the notch 501, and the bottle cap will fall from the notch 501. If the bottle cap is positioned correctly, its width is larger than the width of the notch 501, and the bottle cap will pass through the notch 501 and enter the milling portion 6.

When the lever driving cam 6047 does not apply thrust to the lever mechanism 6042, the petal block 60461 of the milling head 6046 is reset, so that the ejector pin 6044 retreats, and the ejector pin 6044 retreats through the expansion head push rod 6043 to reset the lever mechanism 6042.

[0086] like Fig.13 As shown, the milling cutter mechanism includes a milling cutter slider 6048 slidably connected to the side wall of the milling operation box 6041, a milling cutter 6049 is arranged on the milling cutter slider 6048, a milling cutter displacement cam 60410 is arranged on the milling spindle 601, and a milling cutter displacement bearing 60411 and a reset spring 60412 cooperating with the milling cutter displacement cam 60410 are arranged on the milling cutter slider 6048, and the two ends of the reset spring 60412 are respectively connected to the milling operation box 6041 and the milling cutter slider 6048; the milling cutter displacement cam 60410 rotates to push the milling cutter displacement bearing 60411, and drives the milling cutter 6049 to approach the milling head 6046 through the milling cutter slider 6048, and under the action of the reset spring 60412, drives the milling cutter 6049 away from the milling head 6046 through the milling cutter slider 6048.

[0087] like Figures 8 to 10As shown, the milling ejection unit 602 includes a milling ejection box 6021 and a milling ejection mechanism, wherein the milling ejection box 6021 is provided with a milling ejection driving gear 6022 fixed on the milling spindle 601, a milling ejection transmission shaft 6023, and a milling ejection transmission gear 6024 fixed on the milling ejection transmission shaft 6023 and meshing with the milling ejection driving gear 6022, and a guide rail groove 6025 is provided on the side wall of the milling ejection transmission shaft 6023.

The power is transmitted from the milling spindle 601, the milling ejection driving gear 6022, and the milling ejection transmission gear 6024 to the milling ejection transmission shaft 6023, so that the guide rail groove 3025 rotates, and the milling follower wheel 6028, under the guidance of the guide rail groove 6025, drives the end of the milling ejector rod 6027 to approach or move away from the milling head 6046 through the milling ejection slider 6026; the milling head 6046 is covered with a milling withdrawal ring 6029, and the milling withdrawal ring 6029 and the milling ejection slider 6026 are fixed by a connecting rod.

[0088] When the milling head 6046 contracts, the bottle cap can be pushed in, and when the milling head 6046 expands, the bottle cap can be fixed, so it will not shake due to the force of the milling cutter 6049, affecting the milling effect. Through the contraction and expansion of the milling head 6046, in conjunction with the actions of the milling push rod 6027 and the milling return ring 6029, the milling function of the milling part 6 and the input and output of materials are realized.

[0089] like Fig.11 and Fig.12 As shown, the milling feeding unit 603 includes a milling feeding slider 6031 slidably connected to the side wall of the milling feeding box 6021, a milling feeding cam 6032 is fixed on the milling spindle 601, and the milling feeding slider 6031 is fixed with milling feeding bearings 6033 located on both sides of the milling feeding cam 6032. When the milling feeding cam 6032 rotates, the milling feeding slider 6031 slides to the other side by contacting the milling feeding bearing 6033 on one side; the milling feeding slider 60 The sliding direction of 31 is perpendicular to the sliding direction of the milling feed slider 6026, and the milling feed slider 6031 is provided with a milling feed tongue plate, and the milling feed tongue plate is provided with adjacent milling grooves 1 6034 and 6035, and the milling groove 1 6034 is located between the milling feed slider 6031 and the milling groove 2 6035, the milling groove 1 6034 is used to receive the bottle caps falling from the guide track, and the milling groove 2 6035 is used to receive the bottle caps withdrawn from the milling head 6046.

[0090] refer to Figure 23a to Figure 23h The operation process of the milling unit 6 is as follows (the three bottle caps involved in the process description are defined as the first bottle cap, the second bottle cap and the third bottle cap respectively):

[0091] S1. Fig.23a , the milling groove 6034 moves to below the output end of the lower guide track 5, and the lower guide track 5 outputs the first bottle cap to the milling groove 6034;

[0092] S2. Figure 23b and Fig.23c , the milling groove 6034 moves to between the milling head 6046 and the milling push rod 6027, the milling push slider 6026 pushes the milling push rod 6027 to push the first bottle cap on the milling groove 6034 into the milling head 6046, and at this time, the milling withdrawal ring 6029 moves from the head of the milling head 6046 to the root of the milling head 6046;

[0093] S3. Fig.23d , the milling feeding slider 6031 moves the milling groove 2 6035 to between the milling head 6046 and the milling top rod 6027, and at the same time, the milling head 6046 cooperates with the milling cutter 6049 to complete the milling operation. At this time, the milling groove 1 6034 returns to the bottom of the lower guide track 5 to receive the second bottle cap output by the lower guide track;

[0094] S4. Fig.23e , the milling push slider 6026 pulls back the milling push rod 6027, and at this time the milling withdrawal ring 6029 is synchronously pulled back to the head of the milling expansion head 6046, so that the first bottle cap on the milling expansion head 6046 is withdrawn to the milling groove 2 6035;

[0095] S5. Figure 23f The milling feeding slider 6031 feeds the milling groove 2 6035 carrying the first bottle cap into the unloading part 7, and at the same time feeds the milling groove 1 6034 carrying the second bottle cap to between the milling head 6046 and the milling ejector rod 6027;

[0096] S6. Figure 23g , the milling push rod pushes the second bottle cap into the milling expansion head 6046;

[0097] S7. Figure 23h , the milling feeding slider 6031 drives the milling groove 2 6035 to return. During the returning process, since the milling push rod 6027 has not returned to its position, the first bottle cap on the milling groove 2 6035 hits the milling push rod 6027, rolls out of the milling groove 2 6035 and enters the unloading part 7. When the milling groove 1 6034 moves to the bottom of the lower guide track 5, the third bottle cap output by the lower guide track is output to the milling groove 1 6034.

[0098] like Fig.17 As shown, a correction bearing 60413 is installed on the milling operation box 6041, and the correction bearing 60413 is located on the side of the milling head 6046 away from the milling cutter 6049. When the bottle cap is pushed into the milling head 6046, if there is a tilt, when passing through the correction bearing 60413, the correction bearing 60413 will correct the position of the bottle cap to make it coaxial with the milling head 6046; on the other hand, since the correction bearing 60413 and the milling cutter 6049 are arranged relative to each other, the lateral force of the milling cutter 6049 on the milling head 6046 can be offset to ensure that the milling head 6046 is not deformed.

[0099] Further, such as Figure 8 and Fig. 20 As shown, the milling head 6046 is wrapped with a dust hood 606, and the bottom of the dust hood 606 is connected to a vacuum cleaner through a dust suction pipe 607, which is used to suck out the debris generated during the milling process, avoiding metal dust from falling on other transmission parts of the equipment, reducing the difficulty of equipment maintenance, and also ensuring the cleanliness of the factory area.

[0100] like Figure 8 As described, a connecting plate is provided on the milling ejector box 6021, and a steel brush mounting seat 608 is installed on the connecting plate. A steel brush (not shown in the figure) is fixed below the steel brush mounting seat 608. The steel brush is located above the intersection of the axis of the milling ejector rod 6027 and the axis of the moving direction of the milling feed slider 6031. When the bottle cap is ejected to the milling groove 2 6035 after milling (the bottle cap is still rotating at this time), it will contact the steel brush above, and the steel brush will brush away the debris existing in the milled part of the bottle cap.

[0101] like Fig.21 and Fig. 22 As shown, the feeding section 7 includes a feeding chute 701 which is tilted, the bottom surface of the feeding chute 701 is hollowed out and paved with a mesh plate 702, and a chip collecting bucket is fixed below the feeding chute 701, and the chip collecting bucket is used to receive the debris falling from the mesh plate 702. Preferably, the chip collecting bucket includes a connecting bucket 703 and a drawer box 704, the upper part of the connecting bucket 703 is fixed below the bottom surface of the feeding chute 701, and the lower part of the connecting bucket 703 forms a slideway structure of the drawer box 704, and the drawer box 704 is slidably connected to the lower part of the connecting bucket 703. The feeding chute 701 of the feeding section 7 adopts a double-layer design, and the upper and lower layers are separated by a mesh plate 702. The bottle caps with embossed characters slide down along the mesh plate 702, and the debris on the bottle caps passes through the mesh plate 702 and enters the chip collecting bucket at the lower part, which can prevent most of the debris from falling into the bottle cap recovery box, reducing the workload during subsequent packing.

[0102] The end face of the feeding chute 701 is provided with a box dividing shaft 705 and a box dividing driving part 706 for driving the box dividing shaft 705 to rotate. A box dividing plate 707 is fixed on the shaft. The box dividing plate 707 is connected to the end of the feeding chute 701. The box dividing shaft 705 is used to control the box dividing plate 707 to tilt to both sides in different directions. Preferably, a counting sensor 708 is installed at the side wall of the feeding chute 701. Through the cooperation of the box dividing plate 707 and the counting sensor 708, bottle cap recovery boxes can be placed on both sides of the box dividing plate 707. When a certain number of bottle caps are filled in the recovery box on one side, the box dividing cover rotates to the other side to cover the other recovery box. In this way, when the bottle cap recovery box is replaced, the feeding of the bottle caps will not be interrupted (and the embossing and milling operations will not be interrupted), thereby ensuring the continuity of the operation.

[0103] Furthermore, a lamp track is fixed on the frame, and a lamp 8 is installed on the lamp track. The lamp is located above the embossing part 4 and the milling part 6, which is convenient for workers to operate or repair the equipment.

[0104] In addition, due to the setting of the clutch 304, manual automatic control can be achieved, so a hand wheel 309 will be installed on the embossing spindle 401 and the milling spindle 601 for manually rotating the embossing spindle 401 and the milling spindle 601 to achieve manual power input.

[0105] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
