Description

Technical Field

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

[0002] For common aluminum caps, convex letters (patterns) are extruded on the side surface (cylindrical surface) of the aluminum 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 machine. Milling the bright surface of the convex letter is to increase the beauty of the cap.

[0003] When milling the letters of the cap, it is usually necessary to fix the cap on a device that can accurately control the position. Common fixing methods include fixture fixing, vacuum adsorption, magnetic fixing, mechanical chucks, etc. Fixture fixing may apply uneven pressure to the cap, resulting in deformation or damage to the cap; the fixing force of vacuum adsorption and magnetic fixing is often insufficient, which is not conducive to the operation of the milling cutter; mechanical chucks may leave indentations or scratches on the edge of the cap.

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

[0005] The purpose of the utility model is to provide a milling operation unit for a milling station of a full-automatic convex letter and milling machine, which adopts the method of fixing the cap with an expanding head to improve the processing accuracy, stability and efficiency.

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

[0007] A milling operation unit for a milling station of a full-automatic convex letter and milling machine includes a milling spindle, a milling operation box body, a lever mechanism, an expanding head ejector rod, a thimble, a milling rotating shaft, a driving part for driving the milling rotating shaft, a milling expanding head and a milling cutter mechanism;

[0008] The milling spindle is installed on the milling operation box body through bearings, one end of which is used to input external power, and the other end is fixed with a lever driving cam;

[0009] The lever mechanism is installed on the milling operation box body;

[0010] The milling spindle is installed on the milling operation box body through bearings. Both ends of the milling spindle are open and hollow, and a milling expansion head is fixed at one end. The milling expansion head is hollow, and the end far from the milling spindle includes several petal blocks arranged in a ring and capable of radially expanding or contracting. The thimble is located inside the milling expansion head. One end of the thimble is a conical structure and is located on the side of the petal blocks. The expansion head push rod is located inside the milling spindle. One end of the expansion head push rod is fixed to the other end of the thimble. The other end of the expansion head push rod protrudes from the end of the milling spindle far from the milling expansion head and is connected to one end of the lever mechanism through a bearing. The other end of the lever mechanism is adjacent to the lever drive cam.

[0011] Furthermore, the milling cutter mechanism includes a milling cutter slider slidably connected to the side wall of the milling operation box body. A milling cutter is provided on the milling cutter slider. A milling cutter displacement cam is provided on the milling spindle. A milling cutter displacement bearing and a return spring are provided on the milling cutter slider and are in cooperation with the milling cutter displacement cam. Two ends of the return spring are respectively connected to the milling operation box body and the milling cutter slider; when the milling cutter displacement cam rotates, it pushes the milling cutter displacement bearing, and the milling cutter is driven by the milling cutter slider to approach the milling expansion head. Under the action of the return spring, the milling cutter is driven by the milling cutter slider to move away from the milling expansion head.

[0012] Furthermore, a correction bearing is installed on the milling operation box body and is located on the side of the milling expansion head far from the milling cutter.

[0013] Furthermore, a dust suction cover is wrapped outside the milling expansion head, and the bottom of the dust suction cover is connected to a dust collector through a dust suction pipe.

[0014] Furthermore, a handwheel is installed at one end of the milling spindle.

[0015] Furthermore, it includes a lamp for providing illumination to the operation unit.

[0016] The advantages of the present utility model are as follows:

[0017] 1. Using an expansion head to fix the bottle cap can provide very precise concentricity and positioning accuracy. By expanding to clamp the inner diameter of the workpiece, the clamping force can be evenly applied, thus ensuring the stability of the bottle cap during the processing and preventing rotation. Compared with the traditional fixing method, it has the advantages of less surface damage to the workpiece and high fixing strength;

[0018] 2. Using the lever method to achieve the contraction and expansion of the expansion head, a single power spindle input method can be adopted to achieve the coordination with the action of the milling cutter mechanism, and the integration degree of the power transmission structure is high;

[0019] 3. A dust-proof cover and a dust suction pipeline are added, which avoids metal dust from falling on other transmission parts of the equipment, reduces the difficulty of equipment maintenance, and also ensures the cleanliness of the factory area. Description of the Drawings

[0059] The present invention is further described in detail below with reference to 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 drawings. 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. Therefore, it should not be understood as a limitation on the present invention.

[0060] like Figure 1 As shown, this embodiment provides a fully automatic embossing and milling machine. Based on the bottle cap processing route, it integrates a loading unit 1, an upper guide rail 2, an embossing unit 4, a lower guide rail 5, a milling unit 6, and a discharge unit 7. Furthermore, in this solution, the embossing unit 4 and the milling unit 6 are driven by a single integrated power unit 3. This reduces the size of the equipment, reduces factory floor space, and lowers costs.

[0061] like Figures 2 to 4As shown in the figure, 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 position, and workers can pour unprocessed caps into the hopper 101. The vibrating disk 102 is installed directly below the hopper 101 and is used to receive the caps output from the hopper 101. The cap aligning section 103 includes an aligning disk 1031, an aligning section housing 1032 and an aligning drive section 1033 (i.e., a motor) for driving the aligning disk 1031 to rotate. The aligning disk 1031 is disc-shaped, and a number of cap accommodating slots 501 are circumferentially provided thereon. 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 accommodating slots 501 is provided on the bottom surface. The output end of the vibrating disk 102 is connected to the input port of the aligning section housing 1032, and the output port of the aligning disk 1031 housing is connected to the upper guiding track 2.

[0062] In the feeding section 1, the operation process of the caps is as follows: The caps enter the vibrating disk 102 from the hopper 101 and are output to the aligning disk 1031 through the vibrating disk 102. Due to its unique structural design, only the caps with the opening facing upwards or downwards can enter the cap accommodating slots 501 of the aligning disk 1031. The aligning disk 1031 rotates, and under the action of centrifugal force, the 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 caps with the opening facing downwards from the cap accommodating slots 501, so as to ensure that the caps output from the aligning section 103 are all neatly with the opening facing upwards, thereby ensuring the accurate positions of the raised characters and milled characters on the caps.

[0063] As Figure 1 shown in the figure, the two ends of the upper guiding track 2 are respectively connected to the output port of the aligning disk and the raised character section 4, and a section in the middle is designed as a structure with a 90° twist, which can twist the caps from the vertical direction to the horizontal direction and output them.

[0064] 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 in the figure, the integrated power section 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, which 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, which is used to input power to the milled character section 6. A chain drive is provided between the driving sprocket 301 and the driven sprockets 305, and the power transmission and separation between the driven sprockets 305 and the power rotating shafts 303 are realized through the clutches 304.

[0065] Preferably, the clutch 304 includes a shift lever 3041, a horizontal moving lever 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 by a spline 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 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 lever 3042 is disposed 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 shift lever 3041 is rotatably connected to the bottom plate and is used to control the horizontal moving lever 3042 to move forward or backward in the X direction. Both ends of the shift fork 3043 are fixed to the bushing 3046 and the horizontal moving lever 3042 respectively. When the shift lever 3041 controls the horizontal moving lever 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 shift 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.

[0066] As Figure 19 and Figure 20 shown, the two power rotating shafts 303 respectively correspond to the power outputs of the convex character part 4 and the milled character part 6. A clutch 304 is provided on each power rotating shaft 303. Whether the power of the convex character part 4 and the milled character part 6 is input can be controlled by adjusting their respective clutches 304. 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.

[0067] 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 top spring 3045 are tightly abutted between the spring seat 3044 and the bushing 3046. The first tooth 3047 and the second tooth 3048 are tightly abutted by 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.

[0068] As Figures 5 to 7As shown, the embossing part 4 includes an embossing spindle 401, a grinding tool unit 403, an embossing ejecting unit 404, and an embossing feeding unit 405 located between the grinding tool unit 403 and the embossing ejecting unit 404; the embossing spindle 401 passes through the grinding tool 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, transmits power to the embossing spindle 401, and transmits power to the grinding tool unit 403, the embossing feeding unit 405 and the embossing ejecting unit 404 respectively through the embossing spindle 401.

[0069] The mold unit 403 includes a die shaft 4031 and a punch shaft 4032 parallel to the embossing main shaft 401. An embossing mold gear 4033 is fixed on the embossing main shaft 401. A die 4034 and a die gear 4035 engaged with the embossing mold gear 4033 are fixed on the die shaft 4031. A punch 4036 and a punch gear 4037 engaged with the die gear 4035 are fixed on 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.

[0070] The embossing unit 404 includes a embossing housing 4041 and a embossing mechanism. Within the embossing housing 4041 are located an embossing driving gear 4042 fixed to the embossing spindle 401, an embossing transmission shaft 4043, and an embossing transmission gear 4044 fixed to the embossing transmission shaft 4043 and meshing with the embossing driving gear 4042. A guide groove 4045 is defined on the sidewall of the embossing transmission shaft 4043. The embossing mechanism includes an embossing slider 4046 slidably connected to the sidewall of the embossing housing 4041. Mounted on the embossing slider 4046 are a embossing rod 4048 and a embossing follower wheel 4047 that engages with the guide groove 4045. The embossing rod 4048 is coaxially arranged with the punch 4036. Power is transmitted from the embossing main shaft 401, the embossing ejection driving gear 4042, and the embossing ejection transmission gear 4044 to the embossing ejection transmission shaft 4043, causing the guide rail 4045 to rotate. The embossing follower wheel 4047, guided by the guide rail 4045, drives the end of the embossing ejector rod 4048 toward or away from the punch 4036 via the embossing ejection slider 4046. The punch 4036 is covered with a embossing ejection ring 4049, which is fixed to the embossing ejection slider 4046 by a connecting rod.

[0071] The raised-character feeding unit 405 includes a raised-character feeding slider 4051 slidably connected to the side wall of the raised-character ejector 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, by contacting the raised-character feeding bearing 4053 on one side, the raised-character feeding slider 4051 slides towards the other side. The sliding direction of the raised-character feeding slider 4051 is perpendicular to the sliding direction of the raised-character ejector 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. The raised-character groove one 4054 is located between the raised-character feeding slider 4051 and the raised-character groove two 4055. The raised-character groove one 4054 is used to receive the caps dropped from the upper guiding track 2, and the raised-character groove two 4055 is used to receive the caps withdrawn from the punch 4036.

[0072] Reference Figures 23a to 23h , the operation process of the raised-character part 4 is as follows (the three caps involved in the process description are respectively defined as the first cap, the second cap, and the third cap):

[0073] S1. As Figure 23a , the raised-character groove one 4054 moves to the lower part of the output end of the upper guiding track 2, and the upper guiding track 2 outputs the first cap to the raised-character groove one 4054;

[0074] S2. As Figure 23b and Figure 23c , the raised-character groove one 4054 moves between the punch and the raised-character ejector rod 4048. The raised-character ejector slider 4046 pushes the raised-character ejector rod 4048 to push the first cap on the raised-character groove one 4054 into the punch 4036. At this time, the raised-character stripper ring 4049 moves from the head of the punch 4036 to the root of the punch 4036;

[0075] S3. As Figure 23d , the raised-character feeding slider 4051 moves the raised-character groove two 4055 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 one 4054 returns to the lower part of the upper guiding track 2 and receives the second cap output by the upper guiding track 2;

[0076] S4. As Figure 23e , the raised-character ejector slider 4046 pulls back the raised-character ejector rod 4048. At this time, the raised-character stripper ring 4049 is synchronously pulled back to the head of the punch 4036, so that the first cap on the punch 4036 is withdrawn to the raised-character groove two 4055;

[0077] S5. As Figure 23fThe embossed feeding slider 4051 feeds the embossed groove 2 4055 carrying the first bottle cap into the lower guide track 5, and at the same time feeds the embossed groove 1 4054 carrying the second bottle cap to between the punch 4036 and the embossed ejector rod 4048;

[0078] S6. Figure 23g , the convex push rod 4048 pushes the second bottle cap into the punch 4036;

[0079] S7. Figure 23h The embossed feeding slider 4051 drives the embossed groove 2 4055 to return to its original position. During the return process, since the embossed push rod 4048 has not returned to its original 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.

[0080] Through the above cycle, the bottle cap embossing process and the input and output of the embossing unit 4 are achieved. During the above process, the mold unit 403, the embossing ejection unit 404, and the embossing feeder unit 405 are all driven by a single embossing spindle 401. The transmission structure is highly integrated and automated, further reducing the size of the equipment and reducing costs compared to solutions with multiple power sources, while also ensuring production efficiency.

[0081] The two ends of the lower guide rail 5 are connected to the convex part 4 and the milling part 6 respectively. Figure 10 As shown, a notch 501 having 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. However, 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.

[0082] 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 connected to the milling part power sprocket 307 through a chain, transmits power to the milling spindle 601, and transmits power to the milling spindle 601 and transmits power to the milling top material unit 602, the milling feeding unit 603 and the milling operation unit 604 through the milling spindle 601.

[0083] The milling character operation unit 604 includes a milling character operation box body 6041, a lever mechanism 6042, a swelling head ejector rod 6043, a thimble 6044, a milling character rotating shaft 6045, a milling character rotating shaft driving part 609 (i.e., a motor) for driving the milling character rotating shaft 6045, a milling character swelling head 6046 and a milling cutter mechanism. The milling character rotating shaft 6045 is rotationally connected to the milling character operation box body 6041 through a bearing, and the lever mechanism 6042 is installed on the milling character operation box body 6041. As Figure 9 , Figure 15 and Figure 16 shown, both ends of the milling character rotating shaft 6045 are open and hollow, and one end is fixed with the milling character swelling head 6046. The milling character swelling head 6046 is hollowly arranged, and the end far from the milling character rotating shaft 6045 includes a plurality of petal blocks 60461 arranged in a ring shape and capable of radially expanding or contracting. The thimble 6044 is located inside the milling character 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 milling character 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 milling character rotating shaft 6045 far from the milling character 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 milling character main shaft 601. A lever driving cam 6047 is fixed to 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 swelling head ejector rod 6043 slides toward the thimble 6044 side, thereby driving the thimble 6044 to expand the milling character 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 milling character swelling head 6046 reset, causing the thimble 6044 to retract. The retraction of the thimble 6044 causes the lever mechanism 6042 to reset through the swelling head ejector rod 6043.

[0084] 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 body 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 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 milling character 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 through the milling cutter slider 6048, the milling cutter 6049 is driven to approach the milling character swelling head 6046. Under the action of the return spring 60412, through the milling cutter slider 6048, the milling cutter 6049 is driven to move away from the milling character swelling head 6046.

[0085] 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 provided 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 expansion 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 follower wheel 6028 drives the end of the character milling and blanking rod 6027 to approach or move away from the character milling expansion head 6046 through the character milling and blanking slider 6026. A character milling and blanking withdrawal ring 6029 is sleeved outside the character milling expansion head 6046, and the character milling and blanking withdrawal ring 6029 is fixed to the character milling and blanking slider 6026 through a connecting rod.

[0086] When the character milling expansion head 6046 contracts, the bottle cap can be pushed in. When the character milling expansion head 6046 expands, the bottle cap can be fixed, so that it will not shake due to the action of the milling cutter 6049, affecting the character milling effect. Through the contraction and expansion of the character milling expansion head 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.

[0087] 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 by contacting the character milling and feeding bearing 6033 on one 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 character milling grooves two 6035 are provided on the character milling and feeding tongue plate. The character milling grooves one 6034 are located between the character milling and feeding slider 6031 and the character milling grooves two 6035. The character milling grooves one 6034 are used to receive the bottle caps falling from the guide track, and the character milling grooves two 6035 are used to receive the bottle caps withdrawn from the character milling expansion head 6046.

[0088] Reference Figures 23a to 23h , the operation process of the milling character 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):

[0089] S1. As Figure 23a , the milling character 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 milling character groove 6034;

[0090] S2. As Figure 23b and Figure 23c , the milling character groove 6034 moves between the milling character expanding head and the milling character ejector rod 6027, and the milling character ejecting slider 6026 pushes the milling character ejector rod 6027 to push the first bottle cap on the milling character groove 6034 into the milling character expanding head 6046. At this time, the milling character ejecting ring 6029 moves from the head of the milling character expanding head 6046 to the root of the milling character expanding head 6046;

[0091] S3. As Figure 23d , the milling character feeding slider 6031 moves the milling character groove 6035 between the milling character expanding head 6046 and the milling character ejector rod 6027. At the same time, the milling character expanding head 6046 and the milling cutter 6049 cooperate to complete the milling character operation. At this time, the milling character 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;

[0092] S4. As Figure 23e , the milling character ejecting slider 6026 pulls back the milling character ejector rod 6027. At this time, the milling character ejecting ring 6029 is synchronously pulled back to the head of the milling character expanding head 6046, so that the first bottle cap on the milling character expanding head 6046 is ejected to the milling character groove 6035;

[0093] S5. As Figure 23f , the milling character feeding slider 6031 sends the milling character groove 6035 carrying the first bottle cap into the blanking part 7, and at the same time sends the milling character groove 6034 carrying the second bottle cap between the milling character expanding head 6046 and the milling character ejector rod 6027;

[0094] S6. As [[ID=7*]]Figure 23g , the milling character ejector rod pushes the second bottle cap into the milling character expanding head 6046;

[0095] S7. As Figure 23h , the milling character feeding slider 6031 drives the milling character groove 6035 to return. During the return process, since the milling character ejector rod 6027 is not in place, the first bottle cap on the milling character groove 6035 hits the milling character ejector rod 6027 and rolls out of the milling character groove 6035 into the blanking part 7. When the milling character 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 milling character groove 6034.

[0096] AsFigure 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.

[0097] 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.

[0098] As Figure 8 described, 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, and 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.

[0099] As Figure 21 and Figure 22As shown, the feeding section 7 includes an inclined feeding chute 701. The bottom surface of the feeding chute 701 is hollowed out and covered with a mesh plate 702. A chip collection hopper is fixed below the feeding chute 701 to receive debris falling from the mesh plate 702. Preferably, the chip collection hopper includes a connecting hopper 703 and a drawer box 704. The upper portion of the connecting hopper 703 is fixed below the bottom surface of the feeding chute 701, and the lower portion of the connecting hopper 703 forms a slide structure for the drawer box 704. The drawer box 704 is slidably connected to the lower portion of the connecting hopper 703. The feeding chute 701 of the feeding section 7 adopts a double-layer design, with the mesh plate 702 separating the upper and lower layers. The bottle caps with embossed characters slide along the mesh plate 702, and the debris on the bottle caps passes through the mesh plate 702 and enters the chip collection hopper below. This prevents most of the debris from falling into the bottle cap recovery box, reducing the workload during subsequent packaging. The end face of the feeding chute 701 is equipped with a binning shaft 705 and a binning drive unit 706 for driving the binning shaft 705 to rotate. A binning plate 707 is fixed on the shaft. The binning plate 707 is connected to the end of the feeding chute 701. The binning shaft 705 is used to control the binning plate 707 to tilt in different directions. Preferably, a counting sensor 708 is installed on the side wall of the feeding chute 701. Through the cooperation of the binning plate 707 and the counting sensor 708, bottle cap recovery boxes can be placed on both sides of the binning plate 707. When a certain number of bottle caps are filled in one recovery box, the bin lid rotates to the other side to load the other recovery box. In this way, when the bottle cap recovery box is replaced, the unloading of bottle caps will not be interrupted (and the embossing and milling operations will not be interrupted), thereby ensuring the continuity of the operation.

[0100] Furthermore, a lamp track is fixed on the rack, 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.

[0101] In addition, due to the setting of the clutch 304, manual automatic control can be achieved, so a handwheel 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.

[0102] The above embodiments are only used to illustrate the concept of the present invention, and are not intended to limit the protection of the present invention. Any non-substantial changes to the present invention using this concept should fall within the scope of protection of the present invention.
