Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap processing, in particular to an integrated power unit for a full-automatic convex letter and milling letter machine. Background Art

[0002] For common aluminum bottle caps, the convex letters (patterns) 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 convex letter bright surface is milled by a special milling letter machine. Milling the bright surface of the convex letters is to increase the beauty of the bottle cap.

[0003] At present, the convex letter machines and milling letter machines used in the convex letter and milling letter 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 letter and milling letter machine, so that the convex letter and milling letter use the same set of power system. For this purpose, it is necessary to transform the existing power system to achieve single input and dual output.

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

[0005] The purpose of the utility model is to provide an integrated power unit for a full-automatic convex letter and milling letter 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] An integrated power unit for a full-automatic convex letter and milling letter machine includes a bottom plate, on which an active sprocket, an integrated power source for driving the active sprocket, two power rotating shafts and two clutches are provided. Driven sprockets are connected to the power rotating shafts through bearings, and a convex letter part power sprocket is fixed on one of the power rotating shafts for inputting power to the convex letter device, and a milling letter part power sprocket is fixed on the other power rotating shaft for inputting power to the milling letter device. The active sprocket and the driven sprockets are driven by a chain, and the power transmission and separation between the driven sprockets and the power rotating shafts are realized through clutches.

[0008] Further, the clutch includes a shift lever, a horizontal moving rod, a shift fork and a sleeve. The sleeve is slidably connected to the power rotating shaft through splines and is arranged opposite to the driven sprocket. A first set of teeth is provided on the surface of the sleeve facing the driven sprocket, and a second set of teeth that can engage with the first set of teeth is provided on the surface of the driven sprocket facing the sleeve. The horizontal moving rod is arranged parallel to the power rotating shaft and is slidably connected to the bottom plate. The shift lever is rotatably connected to the bottom plate for controlling the forward or backward movement of the horizontal moving rod. The two ends of the shift fork are respectively fixed on the sleeve and the horizontal moving rod.

[0009] Further, it includes a spring seat and a pressing spring. The spring seat is fixed on the power rotating shaft and is located on the side of the bushing away from the driven sprocket. Both ends of the pressing spring are pressed between the spring seat and the bushing.

[0010] Further, a tensioning mechanism is provided between the driving sprocket and the driven sprocket.

[0011] The advantages of the present utility model are as follows: Compared with the existing design in which the power systems for milling characters and embossing characters are separated, the milling character part and the embossing character part of this application can adopt the same set of power system, greatly reducing the floor area of the factory area and effectively reducing the cost.

[0051] The following further describes the present utility model in detail in combination with embodiments. It should be understood that the orientation or positional relationship indicated by terms such as "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 should not be construed as a limitation to the present utility model.

[0052] As Figure 1 shown, this embodiment proposes a fully automatic convex - character milling machine. According to the processing route of the bottle cap, it 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 blanking section 7 in sequence. 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 lower the cost.

[0053] As Figures 2 to 4As shown in the figure, the feeding section 1 includes a frame, on which a hopper 101, a vibrating bowl 102 and a cap aligning section 103 are fixedly installed. The hopper 101 is located at the uppermost position, and workers can pour unprocessed bottle caps into the hopper 101. The vibrating bowl 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 an aligning disc 1031, an aligning section housing 1032 and an aligning drive section 1033 (i.e., a motor) for driving the aligning disc 1031 to rotate. The aligning disc 1031 is disc-shaped, and a number of cap receiving notches 501 are circumferentially provided. An input port and an output port are provided on the side surface of the aligning section housing 1032, and a blowing port 1034 for blowing air into the cap receiving notches 501 is provided on the bottom surface. The output end of the vibrating bowl 102 is communicated with the input port of the aligning section housing 1032, and the output port of the aligning disc 1031 housing is connected to the upper guiding track 2.

[0054] In the feeding section 1, the operation process of the bottle caps is as follows: The bottle caps enter the vibrating bowl 102 from the hopper 101 and are output to the aligning disc 1031 through the vibrating bowl 102. Due to its unique structural design, only the bottle caps with the opening facing up or down can enter the cap receiving notches 501 of the aligning disc 1031. The aligning disc 1031 rotates, and under the action of centrifugal force, the bottle caps are sent out of the output port and enter the upper guiding track 2. The design of the blowing port 1034 can blow out the bottle caps with the opening facing down from the cap receiving notches 501, so as to ensure that the bottle caps output from the aligning section 103 are all neatly with the opening facing up, thus ensuring the accurate positions of the raised characters and milled characters on the bottle caps.

[0055] As Figure 1 shown in the figure, the two ends of the upper guiding track 2 are respectively connected to the aligning disc output port and the raised character section 4, and a section in the middle is designed as a 90°-twisted structure, which can twist the bottle caps from the vertical direction to the horizontal direction and output them.

[0056] 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 As shown in the figure, the integrated power section 3 includes a bottom plate, on which 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 are provided. Driven sprockets 305 are connected to the power rotating shafts 303 through bearings, and a raised character section power sprocket 306 is fixed on one of the power rotating shafts 303 for inputting power to the raised character section 4, and a milled character section power sprocket 307 is fixed on the other power rotating shaft 303 for inputting 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.

[0057] Preferably, the clutch 304 includes a lever 3041, a horizontal moving rod 3042, a fork 3043, a spring seat 3044, a pressing spring 3045, and a bushing 3046. The bushing 3046 is slidably connected to the power rotating shaft 303 through splines and is disposed 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 engageable 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 1 the coordinate system, in the X direction) and is slidably connected to the bottom plate. The lever 3041 is rotatably connected to the bottom plate and is used to control the horizontal moving rod 3042 to move forward or backward in the X direction. Both ends of the fork 3043 are respectively fixed to the bushing 3046 and the horizontal moving rod 3042. When the lever 3041 controls the horizontal moving rod 3042 to move forward or backward in the X direction, the axial sliding of the bushing 3046 on the power rotating shaft 303 can be realized through the fork 3043, so as to realize the engagement or separation of the first tooth 3047 and the second tooth 3048. When the first tooth 3047 engages with the second tooth 3048, the power output by the integrated power source 302 reaches the power rotating shaft 303 through the driving sprocket 301, the driven sprocket 305, and the bushing 3046, and then is output through the power rotating shaft 303 and the convex / milled character part power sprockets 306 / 307; when the first tooth 3047 is separated from the second tooth 3048, the power output by the integrated power source 302 reaches the driven sprocket 305 through the driving sprocket 301. Since the driven sprocket 305 is connected to the power rotating shaft 303 through a bearing, the driven sprocket 305 idles at this time.

[0058] As Figure 19 and Figure 20 shown, the two power rotating shafts 303 respectively correspond to the power output of the convex character part 4 and the milled character part 6. A clutch 304 is provided on each power rotating shaft 303. By adjusting their respective clutches 304, the power input to the convex character part 4 and the milled character part 6 can be controlled. When the power rotating shaft 303 does not input power, it is in the manual control state, that is, the convex character part 4 or the milled character part 6 is manually driven.

[0059] 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 rotating shaft 303. The spring seat 3044 is located on the side of the bushing 3046 away from the driven sprocket 305. Both ends of the pressing spring 3045 are pressed between the spring seat 3044 and the bushing 3046. The first tooth 3047 and the second tooth 3048 are pressed through the spring force. Preferably, a tensioning mechanism 308 is further provided between the driving sprocket 301 and the driven sprocket 305 for adjusting the tension of the chain.

[0060] As 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.

[0061] 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.

[0062] The embossed material ejection unit 404 includes an embossed material ejection box 4041 and an embossed material ejection mechanism. The embossed material ejection box 4041 is provided with an embossed material ejection driving gear 4042 fixed on the embossed main shaft 401, an embossed material ejection transmission shaft 4043, and an embossed material ejection transmission gear 4044 fixed on the embossed material ejection transmission shaft 4043 and meshing with the embossed material ejection driving gear 4042. 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.

[0063] The raised-character feeding unit 405 includes a raised-character feeding slider 4051 slidably connected to the side wall of the raised-character ejecting box body 4041. A raised-character feeding cam 4052 is fixed on the raised-character main shaft 401. Raised-character feeding bearings 4053 located on both sides of the raised-character feeding cam 4052 are fixed on the raised-character feeding slider 4051. When the raised-character feeding cam 4052 rotates, the raised-character feeding slider 4051 slides to the other side by contacting the raised-character feeding bearing 4053 on one side. The sliding direction of the raised-character feeding slider 4051 is perpendicular to the sliding direction of the raised-character ejecting slider 4046. A raised-character feeding tongue plate is provided on the raised-character feeding slider 4051. Adjacent raised-character grooves one 4054 and raised-character grooves two 4055 are formed on the raised-character feeding tongue plate, and the raised-character grooves one 4054 are located between the raised-character feeding slider 4051 and the raised-character grooves two 4055. The raised-character grooves one 4054 are used to receive the bottle caps falling from the upper guiding track 2, and the raised-character grooves two 4055 are used to receive the bottle caps withdrawn from the punch 4036.

[0064] 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):

[0065] S1. As Figure 23a , the raised-character grooves one 4054 move to the lower part of the output end of the upper guiding track 2, and the upper guiding track 2 outputs the first bottle cap to the raised-character grooves one 4054;

[0066] S2. As Figure 23b and Figure 23c , the raised-character grooves one 4054 move between the punch and the raised-character ejecting rod 4048, and the raised-character ejecting slider 4046 pushes the raised-character ejecting rod 4048 to push the first bottle cap on the raised-character grooves one 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;

[0067] S3. As Figure 23d , the raised-character feeding slider 4051 moves the raised-character grooves two 4055 between the punch 4036 and the raised-character ejecting 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 grooves one 4054 return to the lower part of the upper guiding track 2 and receive the second bottle cap output by the upper guiding track 2;

[0068] S4. As Figure 23e , the raised-character ejecting slider 4046 pulls back the raised-character ejecting 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 withdrawn into the raised-character grooves two 4055;

[0069] S5. As 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;

[0070] S6. Figure 23g , the convex push rod 4048 pushes the second bottle cap into the punch 4036;

[0071] S7. Figure 23h , the embossed feeding slider 4051 drives the embossed groove 2 4055 to return. During the return process, since the embossed push rod 4048 has not returned to its position, the first bottle cap on the embossed groove 2 4055 hits the embossed push rod 4048, rolls out of the embossed groove 2 4055 and enters the lower guide track 5. When the embossed groove 1 4054 moves to the bottom of the upper guide track 2, the third bottle cap output by the upper guide track 2 is output to the embossed groove 1 4054.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] The character milling operation unit 604 includes a character milling operation box body 6041, a lever mechanism 6042, a swelling head ejector rod 6043, a thimble 6044, a character milling rotating shaft 6045, a character milling rotating shaft driving part 609 (i.e., a motor) for driving the character milling rotating shaft 6045, a character milling swelling head 6046, and a milling cutter mechanism. The character milling rotating shaft 6045 is rotatably connected to the character milling operation box body 6041 through a bearing, and the lever mechanism 6042 is installed on the character milling operation box body 6041. As Figure 9 , Figure 15 and Figure 16 shown, both ends of the character milling rotating shaft 6045 are open and hollow, and one end is fixed with the character milling swelling head 6046. The character milling swelling head 6046 is hollowly arranged, and the end far from the character milling rotating shaft 6045 includes a plurality of petal blocks 60461 arranged in a ring and capable of radially expanding or contracting. The thimble 6044 is located inside the character milling swelling head 6046. One end of the thimble 6044 is a conical structure and is located on the side of the petal blocks 60461. The swelling head ejector rod 6043 is located inside the character milling rotating shaft 6045. One end of the swelling head ejector rod 6043 is fixed to the other end of the thimble 6044. The other end of the swelling head ejector rod 6043 exposes from the end of the character milling rotating shaft 6045 far from the character milling swelling 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 character milling main shaft 601. A lever driving cam 6047 is fixed to one end of the character milling main shaft 601. The lever driving cam 6047 is used to push the lever mechanism 6042 to rotate, so that the swelling head ejector rod 6043 slides toward the thimble 6044 side, thereby driving the thimble 6044 to expand the character milling swelling head 6046. When the lever driving cam 6047 does not apply a thrust to the lever mechanism 6042, the petal blocks 60461 of the character milling swelling head 6046 reset, so that the thimble 6044 retracts. The retraction of the thimble 6044 causes the lever mechanism 6042 to reset through the swelling head ejector rod 6043.

[0076] As Figure 13 shown, the milling cutter mechanism includes a milling cutter slider 6048 slidably connected to the side wall of the character milling operation box body 6041. A milling cutter 6049 is provided on the milling cutter slider 6048. A milling cutter displacement cam 60410 is provided on the character milling main shaft 601. A milling cutter displacement bearing 60411 and a return spring 60412 for cooperating with the milling cutter displacement cam 60410 are provided on the milling cutter slider 6048. Two ends of the return spring 60412 are respectively connected to the character milling operation box body 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 character milling swelling 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 character milling swelling head 6046 through the milling cutter slider 6048.

[0077] 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 and following 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 and expanding head 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 and following wheel 6028 drives the end of the character milling and blanking rod 6027 to approach or move away from the character milling and expanding head 6046 through the character milling and blanking slider 6026. A character milling and unloading ring 6029 is sleeved outside the character milling and expanding head 6046, and the character milling and unloading ring 6029 is fixed to the character milling and blanking slider 6026 through a connecting rod.

[0078] When the character milling and expanding head 6046 contracts, the bottle cap can be pushed in. When the character milling and expanding head 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 and expanding head 6046, cooperating with the actions of the character milling and blanking rod 6027 and the character milling and unloading ring 6029, the character milling function of the character milling part 6 and the input and output of materials are realized.

[0079] As Figure 11 and Figure 12 As 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 side in contact. 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 and expanding head 6046.

[0080] 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 defined as the first bottle cap, the second bottle cap, and the third bottle cap):

[0081] 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;

[0082] S2. As shown in Figure 23b and Figure 23c , the character milling groove 6034 moves between the character milling head and the character milling ejector rod 6027. 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 head 6046. At this time, the character milling ejector ring 6029 moves from the head of the character milling head 6046 to the root of the character milling head 6046;

[0083] S3. As shown in Figure 23d , the character milling feeding slider 6031 moves the character milling groove 6035 between the character milling head 6046 and the character milling ejector rod 6027. At the same time, the character milling head 6046 and the milling cutter 6049 cooperate 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;

[0084] 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 ejector ring 6029 is synchronously pulled back to the head of the character milling head 6046, so that the first bottle cap on the character milling head 6046 is ejected into the character milling groove 6035;

[0085] 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 head 6046 and the character milling ejector rod 6027;

[0086] S6. As shown in Figure 23g , the character milling ejector rod pushes the second bottle cap into the character milling head 6046;

[0087] 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.

[0088] As shown inFigure 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.

[0089] Further, as Figure 8 and Figure 20 shown, a dust suction hood 606 is wrapped outside the character milling chuck 6046. The bottom of the dust suction 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 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.

[0090] As Figure 8 described, a connecting plate is provided on the character milling blanking box body 6021, and 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.

[0091] As Figure 21 and Figure 22 shown, the blanking part 7 includes an inclined blanking groove 701. The bottom surface of the blanking groove 701 is hollowed out and provided with a perforated plate 702. A chip collecting hopper is fixed below the blanking groove 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 groove 701, and the lower part of the connecting hopper 703 forms a slideway structure for the drawer box 704. The drawer box 704 is slidably connected to the lower part of the connecting hopper 703. The blanking groove 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 with convex characters after 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 packing.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.
