Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap processing, in particular to a convex character station for a full-automatic convex character milling machine. Background Technique

[0002] For common aluminum bottle caps to form convex characters (patterns), the convex characters are extruded on the side surface (cylindrical surface) of the aluminum bottle cap by means of rolling with a concave die and a convex die, and then the bright surface of the convex characters is milled by a special milling machine. Milling the bright surface of the convex characters is to increase the aesthetic degree of the bottle cap.

[0003] At present, the convex character machine and the milling machine used in the convex character milling process are generally two independent devices, with two independent power systems. The integration degree of power transmission is low, the floor area of the equipment is large, and the processing is not continuous, resulting in difficult reduction of production costs and limited improvement of efficiency. To solve the above defects, the applicant intends to develop a full-automatic convex character milling machine, so that the convex character and milling use the same set of power system. Therefore, it is necessary to transform the power transmission system of the existing convex character machine to achieve the effect of single power input and multi-mechanism linkage.

[0004] Based on this, this case is proposed. Summary of the Invention

[0005] The purpose of the utility model is to provide a convex character station for a full-automatic convex character milling machine to solve the above problems.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A convex character station for a full-automatic convex character milling machine includes a convex character main shaft, a mold unit, a convex character ejector unit, and a convex character feeding unit located between the mold unit and the convex character ejector unit; the convex character main shaft penetrates through the mold unit, the convex character feeding unit, and the convex character ejector unit, and a convex character sprocket is fixed on the convex character main shaft. The convex character sprocket is used to input external power, transmit the power to the convex character main shaft, and then transmit the power to the mold unit, the convex character feeding unit, and the convex character ejector unit respectively through the convex character main shaft.

[0008] Further, the mold unit includes a concave die shaft and a convex die shaft. A convex character grinding gear is fixed on the convex character main shaft, a concave die and a concave die gear meshing with the convex character grinding gear are fixed on the concave die shaft, a convex die and a convex die gear meshing with the concave die gear are fixed on the convex die shaft, and the convex die and the concave die can cooperate with each other to realize the convex character operation of the bottle cap.

[0009] Further, the raised-character ejecting unit includes a raised-character ejecting box body and a raised-character ejecting mechanism. Inside the raised-character ejecting box body, there are a raised-character ejecting driving gear fixed on the raised-character main shaft, a raised-character ejecting transmission shaft, and a raised-character ejecting transmission gear fixed on the raised-character ejecting transmission shaft and meshing with the raised-character ejecting driving gear. A guiding rail groove is formed on the side wall of the raised-character ejecting transmission shaft. The raised-character ejecting mechanism includes a raised-character ejecting slider slidably connected to the side wall of the raised-character ejecting box body. A raised-character ejecting rod and a raised-character follower wheel cooperating with the guiding rail groove are installed on the raised-character ejecting slider. The raised-character ejecting rod is coaxially arranged with the convex die. Under the guidance of the guiding rail groove, the raised-character follower wheel drives the end of the raised-character ejecting rod to approach or move away from the convex die through the raised-character ejecting slider. A raised-character stripping ring is sleeved outside the convex die, and the raised-character stripping ring is fixed to the raised-character ejecting slider through a connecting rod.

[0010] Further, the raised-character feeding unit includes a raised-character feeding slider slidably connected to the side wall of the raised-character ejecting box body. A raised-character feeding cam is fixed on the raised-character main shaft. Raised-character feeding bearings located on both sides of the raised-character feeding cam are fixed on the raised-character feeding slider. When the raised-character feeding cam rotates, it makes the raised-character feeding slider slide to the other side by contacting the raised-character feeding bearing on one side. The sliding direction of the raised-character feeding slider is perpendicular to the sliding direction of the raised-character ejecting slider. A raised-character feeding tongue plate is provided on the raised-character feeding slider. Adjacent raised-character grooves I and II are formed on the raised-character feeding tongue plate, and the raised-character groove I is located between the raised-character feeding slider and the raised-character groove II. The raised-character groove I is used to receive the bottle caps input from the outside, and the raised-character groove II is used to receive the bottle caps ejected from the convex die.

[0011] Further, a hand wheel is installed at one end of the raised-character main shaft.

[0012] Further, it includes a lamp for providing illumination to the working station.

[0013] The advantages of the present utility model are as follows: Inside the raised-character part, a cam and a transmission shaft are used to realize one power input source to drive multiple working mechanisms to operate. The transmission part has a high integration degree and a high degree of automation, reducing the volume of the equipment. Compared with the multi-power-source solution, the cost is reduced, and at the same time, the production efficiency is ensured. Description of the Drawings

[0053] The following further describes the present utility model in detail in conjunction with embodiments. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. in the text is based on the orientation or positional relationship shown in the attached Figure 1 coordinate system, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0054] As Figure 1 shown, this embodiment proposes a fully automatic convex character milling machine, which successively integrates a feeding section 1, an upper guiding track 2, a convex character section 4, a lower guiding track 5, a milling character section 6 and a feeding section 7 according to the processing route of the bottle cap. At the same time, in this solution, the convex character section 4 and the milling character section 6 are driven by the same integrated power section 3. This can reduce the volume of the equipment, reduce the floor area of the factory area, and reduce costs.

[0055] As Figures 2 to 4 shown, the feeding section 1 includes a frame, on which a hopper 101, a vibrating disk 102 and a cap aligning section 103 are fixedly installed. Among them, the hopper 101 is located at the topmost, and workers can pour the unprocessed bottle caps into the hopper 101. The vibrating disk 102 is installed directly below the hopper 101 and is used to receive the bottle caps output from the hopper 101. The cap aligning section 103 includes a cap aligning disk 1031, a cap aligning section housing 1032 and a cap aligning driving section 1033 (i.e., a motor) for driving the cap aligning disk 1031 to rotate. The cap aligning disk 1031 is disk-shaped and is circumferentially provided with a plurality of bottle cap receiving notches 501. The side surface of the cap aligning section housing 1032 is provided with an input port and an output port, and the bottom surface is provided with a blowing port 1034 for blowing air into the bottle cap receiving notches 501. The output end of the vibrating disk 102 is communicated with the input port of the cap aligning section housing 1032, and the output port of the cap aligning disk 1031 housing is connected to the upper guiding track 2.

[0056] In the feeding section 1, the operation process of the bottle caps is as follows: The bottle caps enter the vibrating disk 102 from the hopper 101 and are output to the cap arranging disk 1031 through the vibrating disk 102. Due to its unique structural design, only the bottle caps with the opening facing upward or downward can enter the cap accommodating notch 501 of the cap arranging disk 1031. The cap arranging disk 1031 rotates and sends the bottle caps out of the output port into the upper guiding track 2 under the action of centrifugal force. The design of the air blowing port 1034 can blow out the bottle caps with the opening facing downward from the cap accommodating notch 501, so as to ensure that the bottle caps output from the cap arranging section 103 all have the opening facing upward neatly, thus ensuring the accurate positions of the raised characters and milled characters on the bottle caps.

[0057] As Figure 1 shown, the two ends of the upper guiding track 2 are respectively connected to the output port of the cap arranging disk and the raised character section 4, and a section in the middle is designed with a 90° torsion structure, which can twist the bottle caps from the vertical direction to the horizontal direction and output them.

[0058] Before describing the raised character section 4 and the milled character section 6, the integrated power section 3 will be described first. Refer to Figures 17 to 20 shown, the integrated power section 3 includes a bottom plate, on which there are a driving sprocket 301, an integrated power source (i.e., a motor) 302 for driving the driving sprocket 301, two power rotating shafts 303 and two clutches 304. The power rotating shafts 303 are connected with driven sprockets 305 through bearings, and a raised character section power sprocket 306 is fixed on one of the power rotating shafts 303, and the raised character section power sprocket 306 is used to input power to the raised character section 4. A milled character section power sprocket 307 is fixed on the other power rotating shaft 303, and the milled character section power sprocket 307 is used to input power to the milled character section 6. The driving sprocket 301 and the driven sprockets 305 are driven by a chain, and the power transmission and separation between the driven sprockets 305 and the power rotating shafts 303 are realized through the clutches 304.

[0059] Preferably, the clutch 304 includes a shift lever 3041, a horizontal moving rod 3042, a shift fork 3043, a spring seat 3044, a top spring 3045 and a bushing 3046. The bushing 3046 is slidably connected to the power rotating shaft 303 through a spline and is arranged opposite to the driven sprocket 305. A first tooth 3047 is provided on the surface of the bushing 3046 facing the driven sprocket 305, and a second tooth 3048 that can engage with the first tooth 3047 is provided on the surface of the driven sprocket 305 facing the bushing 3046. The horizontal moving rod 3042 is arranged parallel to the power rotating shaft 303 (refer to Figure 1The 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.

[0060] like Figure 19 and Figure 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.

[0061] 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.

[0062] like Figures 5 to 7 As 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.

[0063] The grinding tool unit 403 includes a female die shaft 4031 and a male die shaft 4032 parallel to the embossing main shaft 401. A male die grinding tool gear 4033 is fixed on the embossing main shaft 401, a female die 4034 and a female die gear 4035 meshing with the male die grinding tool gear 4033 are fixed on the female die shaft 4031, a male die 4036 and a male die gear 4037 meshing with the female die gear 4035 are fixed on the male die shaft 4032. The male die 4036 and the female die 4034 can cooperate with each other to realize the embossing operation of the bottle cap.

[0064] The embossing ejector unit 404 includes an embossing ejector box body 4041 and an embossing ejector mechanism. An embossing ejector driving gear 4042 fixed on the embossing main shaft 401, an embossing ejector transmission shaft 4043, and an embossing ejector transmission gear 4044 fixed on the embossing ejector transmission shaft 4043 and meshing with the embossing ejector driving gear 4042 are arranged in the embossing ejector box body 4041. A guide rail groove 4045 is formed on the side wall of the embossing ejector transmission shaft 4043. The embossing ejector mechanism includes an embossing ejector slider 4046 slidably connected to the side wall of the embossing ejector box body 4041. An embossing ejector rod 4048 and an embossing follower wheel 4047 cooperating with the guide rail groove 4045 are installed on the embossing ejector slider 4046. The embossing ejector rod 4048 is coaxially arranged with the male die 4036. Power reaches the embossing ejector transmission shaft 4043 from the embossing main shaft 401, the embossing ejector driving gear 4042, and the embossing ejector transmission gear 4044, causing the guide rail groove 4045 to rotate. Under the guidance of the guide rail groove 4045, the embossing follower wheel 4047 drives the end of the embossing ejector rod 4048 to approach or move away from the male die 4036 through the embossing ejector slider 4046. A male die stripping ring 4049 is sleeved outside the male die 4036, and the male die stripping ring 4049 is fixed to the embossing ejector slider 4046 through a connecting rod.

[0065] The embossing feeding unit 405 includes an embossing feeding slider 4051 slidably connected to the side wall of the embossing ejector box body 4041. An embossing feeding cam 4052 is fixed on the embossing main shaft 401. Embossing feeding bearings 4053 located on both sides of the embossing feeding cam 4052 are fixed on the embossing feeding slider 4051. When the embossing feeding cam 4052 rotates, the embossing feeding slider 4051 slides towards the other side by contacting the embossing feeding bearing 4053 on one side. The sliding direction of the embossing feeding slider 4051 is perpendicular to the sliding direction of the embossing ejector slider 4046. An embossing feeding tongue plate is arranged on the embossing feeding slider 4051. Adjacent embossing grooves one 4054 and embossing grooves two 4055 are formed on the embossing feeding tongue plate. The embossing grooves one 4054 are located between the embossing feeding slider 4051 and the embossing grooves two 4055. The embossing grooves one 4054 are used to receive the bottle caps falling from the upper guide track 2, and the embossing grooves two 4055 are used to receive the bottle caps ejected from the male die 4036.

[0066] Reference Figures 23a to 23h The operation process of the raised character part 4 is as follows (the three bottle caps involved in the process description are respectively defined as the first bottle cap, the second bottle cap, and the third bottle cap):

[0067] S1. As shown in Figure 23a , the raised character groove 4054 moves to the lower part of the output end of the upper guiding rail 2, and the upper guiding rail 2 outputs the first bottle cap to the raised character groove 4054;

[0068] S2. As shown in Figure 23b and Figure 23c , the raised character groove 4054 moves between the punch and the raised character ejector rod 4048, and the raised character ejector slider 4046 pushes the raised character ejector rod 4048 to push the first bottle cap on the raised character groove 4054 into the punch 4036. At this time, the raised character stripping ring 4049 moves from the head of the punch 4036 to the root of the punch 4036;

[0069] S3. As shown in Figure 23d , the raised character feeding slider 4051 moves the raised character groove 4055 to between the punch 4036 and the raised character ejector rod 4048. At the same time, the punch 4036 and the die 4034 cooperate to complete the raised character operation. At this time, the raised character groove 4054 returns to the lower part of the upper guiding rail 2 and receives the second bottle cap output by the upper guiding rail;

[0070] S4. As shown in Figure 23e , the raised character ejector slider 4046 pulls back the raised character ejector rod 4048. At this time, the raised character stripping ring 4049 is synchronously pulled back to the head of the punch 4036, so that the first bottle cap on the punch 4036 is ejected to the raised character groove 4055;

[0071] S5. As shown in Figure 23f , the raised character feeding slider 4051 sends the raised character groove 4055 carrying the first bottle cap into the lower guiding rail 5, and at the same time sends the raised character groove 4054 carrying the second bottle cap between the punch 4036 and the raised character ejector rod 4048;

[0072] S6. As shown in Figure 23g , the raised character ejector rod 4048 pushes the second bottle cap into the punch 4036;

[0073] S7. As shown in Figure 23h , the raised character feeding slider 4051 drives the raised character groove 4055 to return. During the return process, since the raised character ejector rod 4048 is not in place, the first bottle cap on the raised character groove 4055 hits the raised character ejector rod 4048 and rolls out of the raised character groove 4055 into the lower guiding rail 5. When the raised character groove 4054 moves to the lower part of the upper guiding rail 2, the third bottle cap output by the upper guiding rail is output to the raised character groove 4054.

[0074] 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.

[0075] The two ends of the lower guide rail 5 are respectively connected to the convex part 4 and the milling part 6. Figure 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.

[0076] like Figures 8 to 16 As shown, the milling part 6 includes a milling spindle 601, a milling top material unit 602, a milling feeding unit 603 and a milling operation unit 604, and the milling feeding unit 603 is located between the milling top material unit 602 and the milling operation unit 604; the milling spindle 601 passes through the milling top material unit 602, the milling feeding unit 603, and the milling operation unit 604, and a milling sprocket 605 is fixed on the milling spindle 601, and the milling sprocket 605 is transmission-connected with the milling part power sprocket 307 through a chain, so as to transmit power to the milling spindle 601, and transmit power to the milling top material unit 602, the milling feeding unit 603 and the milling operation unit 604 respectively through the milling spindle 601.

[0077] The milling unit 604 includes a milling operation box 6041, a lever mechanism 6042, a head push rod 6043, a pin 6044, a milling shaft 6045, a milling shaft driving unit 609 (i.e., a motor) for driving the milling shaft 6045, a milling head 6046, and a milling cutter mechanism. The milling shaft 6045 is rotatably connected to the milling operation box 6041 through a bearing, and the lever mechanism 6042 is installed on the milling operation box 6041. Figure 9 , Figure 15 and Figure 16As shown, the milling character rotating shaft 6045 has openings and is hollow at both ends, and a milling character expanding head 6046 is fixed at one end. The milling character expanding head 6046 is hollow inside, and the end away from the milling character rotating shaft 6045 includes several petal blocks 60461 arranged in a ring and capable of radially expanding or contracting. The ejector pin 6044 is located inside the milling character expanding head 6046. One end of the ejector pin 6044 is a conical structure and is located on the side of the petal blocks 60461. The expanding head push rod 6043 is located inside the milling character rotating shaft 6045. One end of the expanding head push rod 6043 is fixed to the other end of the ejector pin 6044. The other end of the expanding head push rod 6043 protrudes from the end of the milling character rotating shaft 6045 away from the milling character expanding head 6046 and is connected to one end of the lever mechanism 6042 through a bearing. The other end of the lever mechanism 6042 is adjacent to one end of the milling character main shaft 601. A lever driving cam 6047 is fixed at one end of the milling character main shaft 601. The lever driving cam 6047 is used to push the lever mechanism 6042 to rotate, so that the expanding head push rod 6043 slides toward the ejector pin 6044 side, thereby driving the ejector pin 6044 to expand the milling character expanding head 6046. When the lever driving cam 6047 does not apply a thrust to the lever mechanism 6042, the petal blocks 60461 of the milling character expanding head 6046 are reset, so that the ejector pin 6044 retracts. The retraction of the ejector pin 6044 causes the lever mechanism 6042 to be reset through the expanding head push rod 6043.

[0078] As Figure 13 shown, the milling cutter mechanism includes a milling cutter slider 6048 slidably connected to the side wall of the milling character operation box 6041. A milling cutter 6049 is provided on the milling cutter slider 6048. A milling cutter displacement cam 60410 is provided on the milling character main shaft 601. A milling cutter displacement bearing 60411 and a return spring 60412 that cooperate with the milling cutter displacement cam 60410 are provided on the milling cutter slider 6048. Both ends of the return spring 60412 are respectively connected to the milling character operation box 6041 and the milling cutter slider 6048. The rotation of the milling cutter displacement cam 60410 pushes the milling cutter displacement bearing 60411, and drives the milling cutter 6049 to approach the milling character expanding head 6046 through the milling cutter slider 6048. Under the action of the return spring 60412, the milling cutter 6049 is driven to move away from the milling character expanding head 6046 through the milling cutter slider 6048.

[0079] As Figures 8 to 10As shown in the figure, the character milling and blanking unit 602 includes a character milling and blanking box body 6021 and a character milling and blanking mechanism. Inside the character milling and blanking box body 6021, there are a character milling and blanking driving gear 6022 fixed on the character milling main shaft 601, a character milling and blanking transmission shaft 6023, and a character milling and blanking driven gear 6024 fixed on the character milling and blanking transmission shaft 6023 and meshing with the character milling and blanking driving gear 6022. A guide rail groove 6025 is formed on the side wall of the character milling and blanking transmission shaft 6023. The character milling and blanking mechanism includes a character milling and blanking slider 6026 slidably connected to the side wall of the character milling and blanking box body 6021. A character milling and blanking rod 6027 and a character milling follower wheel 6028 cooperating with the guide rail groove 6025 are installed on the character milling and blanking slider 6026. The character milling and blanking rod 6027 is coaxially arranged with the character milling expander 6046. Power is transmitted from the character milling main shaft 601, the character milling and blanking driving gear 6022, and the character milling and blanking driven gear 6024 to the character milling and blanking transmission shaft 6023, causing the guide rail groove 3025 to rotate. Under the guidance of the guide rail groove 6025, the character milling follower wheel 6028 drives the end of the character milling and blanking rod 6027 to approach or move away from the character milling expander 6046 through the character milling and blanking slider 6026. A character milling and blanking withdrawal ring 6029 is sleeved outside the character milling expander 6046, and the character milling and blanking withdrawal ring 6029 is fixed to the character milling and blanking slider 6026 through a connecting rod.

[0080] When the character milling expander 6046 contracts, the bottle cap can be pushed in. When the character milling expander 6046 expands, the bottle cap can be fixed, so that it will not shake due to the acting force of the milling cutter 6049, affecting the character milling effect. Through the contraction and expansion of the character milling expander 6046, cooperating with the actions of the character milling and blanking rod 6027 and the character milling and blanking withdrawal ring 6029, the character milling function of the character milling part 6 and the input and output of materials are realized.

[0081] As Figure 11 and Figure 12 shown in the figure, the character milling and feeding unit 603 includes a character milling and feeding slider 6031 slidably connected to the side wall of the character milling and blanking box body 6021. A character milling and feeding cam 6032 is fixed on the character milling main shaft 601. Character milling and feeding bearings 6033 located on both sides of the character milling and feeding cam 6032 are fixed on the character milling and feeding slider 6031. When the character milling and feeding cam 6032 rotates, the character milling and feeding slider 6031 slides to the other side through the character milling and feeding bearing 6033 on one contact side. The sliding direction of the character milling and feeding slider 6031 is perpendicular to the sliding direction of the character milling and blanking slider 6026. A character milling and feeding tongue plate is provided on the character milling and feeding slider 6031. Adjacent character milling grooves one 6034 and two 6035 are formed on the character milling and feeding tongue plate. The character milling groove one 6034 is located between the character milling and feeding slider 6031 and the character milling groove two 6035. The character milling groove one 6034 is used to receive the bottle caps falling from the guide rail, and the character milling groove two 6035 is used to receive the bottle caps withdrawn from the character milling expander 6046.

[0082] Reference Figures 23a to 23h The operation process of the character milling part 6 is as follows (the three bottle caps involved in the process description are respectively defined as the first bottle cap, the second bottle cap, and the third bottle cap):

[0083] S1. As shown in Figure 23a , the character milling groove 6034 moves to the lower part of the output end of the lower guiding track 5, and the lower guiding track 5 outputs the first bottle cap to the character milling groove 6034;

[0084] S2. As shown in Figure 23b and Figure 23c , the character milling groove 6034 moves between the character milling expansion head 6046 and the character milling ejector rod 6027, and the character milling ejector slider 6026 pushes the character milling ejector rod 6027 to push the first bottle cap on the character milling groove 6034 into the character milling expansion head 6046. At this time, the character milling unloading ring 6029 moves from the head of the character milling expansion head 6046 to the root of the character milling expansion head 6046;

[0085] S3. As shown in Figure 23d , the character milling feeding slider 6031 moves the character milling groove 6035 between the character milling expansion head 6046 and the character milling ejector rod 6027. At the same time, the character milling expansion head 6046 cooperates with the milling cutter 6049 to complete the character milling operation. At this time, the character milling groove 6034 returns to the lower part of the lower guiding track 5 and receives the second bottle cap output by the lower guiding track;

[0086] S4. As shown in Figure 23e , the character milling ejector slider 6026 pulls back the character milling ejector rod 6027. At this time, the character milling unloading ring 6029 is synchronously pulled back to the head of the character milling expansion head 6046, so that the first bottle cap on the character milling expansion head 6046 is ejected into the character milling groove 6035;

[0087] S5. As shown in Figure 23f , the character milling feeding slider 6031 sends the character milling groove 6035 carrying the first bottle cap into the blanking part 7, and at the same time sends the character milling groove 6034 carrying the second bottle cap between the character milling expansion head 6046 and the character milling ejector rod 6027;

[0088] S6. As shown in Figure 23g , the character milling ejector rod pushes the second bottle cap into the character milling expansion head 6046;

[0089] S7. As shown in Figure 23h , the character milling feeding slider 6031 drives the character milling groove 6035 to return. During the return process, since the character milling ejector rod 6027 is not in place, the first bottle cap on the character milling groove 6035 hits the character milling ejector rod 6027 and rolls out of the character milling groove 6035 into the blanking part 7. When the character milling groove 6034 moves to the lower part of the lower guiding track 5, the third bottle cap output by the lower guiding track is output to the character milling groove 6034.

[0090] As shown Figure 17 As shown, a correction bearing 60413 is installed on the character milling operation box body 6041. The correction bearing 60413 is located on the side of the character milling chuck 6046 away from the milling cutter 6049. When the bottle cap is pushed into the character milling chuck 6046, if there is an inclination, 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 character milling chuck 6046. On the other hand, since the correction bearing 60413 is arranged opposite to the milling cutter 6049, the lateral force of the milling cutter 6049 on the character milling chuck 6046 can be offset, ensuring that the character milling chuck 6046 does not deform.

[0091] Furthermore, as shown Figure 8 and Figure 20 As shown, a dust suction cover 606 is wrapped outside the character milling chuck 6046. The bottom of the dust suction cover 606 is connected to a vacuum cleaner through a dust suction pipe 607, which is used to suck out the debris generated during the character milling process, avoiding metal dust from falling on other transmission parts of the equipment, reducing the difficulty of equipment maintenance, and at the same time ensuring the cleanliness of the factory area.

[0092] As shown Figure 8 As described above, a connecting plate is provided on the character milling blanking box body 6021. A steel brush mounting seat 608 is installed at 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 point of the axis of the character milling ejector rod 6027 and the axis of the moving direction of the character milling feeding slider 6031. When the bottle cap is withdrawn to the second character milling groove 6035 after character milling (at this time the bottle cap is still rotating), it will contact the steel brush above, and the steel brush will brush off the debris existing on the milled part of the bottle cap.

[0093] As shown Figure 21 and Figure 22 As shown, the blanking part 7 includes an inclined blanking chute 701. The bottom surface of the blanking chute 701 is hollowed out and provided with a perforated plate 702. A chip collecting hopper is fixed below the blanking chute 701, and the chip collecting hopper is used to receive the debris falling from the perforated plate 702. Preferably, the chip collecting hopper includes a connecting hopper 703 and a drawer box 704. The upper part of the connecting hopper 703 is fixed below the bottom surface of the blanking chute 701. The lower part of the connecting hopper 703 forms a slideway structure for the drawer box 704, and the drawer box 704 is slidably connected to the lower part of the connecting hopper 703. The blanking chute 701 of the blanking part 7 adopts a double-layer design, and the upper and lower layers are separated by a perforated plate 702. The bottle caps after convex character milling slide along the upper side of the perforated plate 702, and the debris on the bottle caps passes through the perforated plate 702 and enters the lower chip collecting hopper, which can avoid most of the debris from falling into the bottle cap recycling box, reducing the workload during subsequent boxing.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection 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.
