Description

Technical Field

[0001] This utility model relates to the field of bottle cap processing technology, specifically to an integrated equipment for rolling and embossing metal bottle caps. Background Technology

[0002] Metal bottle caps are commonly used in food sealing packaging. They typically use threads that match the bottle opening to seal or open the bottle. These caps facilitate repeated sealing and opening, improving the ease of use and sealing of the packaging. During the manufacturing process of metal bottle caps, a rolling process is usually used to roll up the edge of the cap opening to reduce its sharpness and prevent hand injuries. An embossing process is also used to create inward-curving threads or anti-slip textures on the cap surface. The threads are used to secure the cap to the bottle, while the anti-slip textures increase the surface roughness of the cap to make it easier to screw on.

[0003] Some existing metal bottle cap equipment still requires manual placement of the bottle cap blank into the designated processing position during the processing. Furthermore, the two processing steps of edge rolling and embossing are relatively independent, and bottle caps are usually not processed in a continuous manner. This is not conducive to improving the production efficiency of capping.

[0004] Based on the above, Chinese Patent Publication No. CN216324736U discloses a production equipment for internally threaded bottle caps, including a base, a first frame on one side of the base surface, a pre-rolling mechanism on one side of the first frame via a fixed bracket, a first gear set at the top of the first frame, a rolling and punching mechanism on the first frame inside the first gear set, a second frame on the base surface outside one side of the first frame, a rolling and opening mechanism on the second frame, a cam divider inside the bottom of the base, a turntable on the middle surface of the base, the vertical output end of the cam divider connected to the bottom end of the turntable, and a feeding mechanism on the base surface on one side of the second frame.

[0005] The bottle cap production equipment disclosed in the above patent uses independent drive mechanisms to process the rolled edges and side threads. This reduces the linkage and coordination between the processing mechanisms, making it easy for errors to occur in the dimensions of the rolled edges and side threads of the cap.

Detailed Implementation

[0033] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, an integrated edge-rolling and embossing device for metal bottle caps includes a machine base 1, an edge-rolling mechanism 2, an embossing mechanism 3, a drive mechanism 4, an edge-rolling transmission mechanism 5, and an embossing transmission mechanism 6. The edge-rolling mechanism 2 is located at the top of the machine base 1 and consists of an edge-rolling punch head 21 and an edge-rolling worktable 22 distributed vertically. The edge-rolling punch head 21 has an edge-rolling groove 23 at its bottom. The embossing mechanism 3 is located at the bottom of the machine base 1 and consists of a matching embossing roller 31 and a bottle cap fixing roller 32. The surfaces of the embossing roller 31 and the bottle cap fixing roller 32 are provided with matching embossing patterns. An embossing swing arm 33 is provided on one side of the embossing roller 31 and is movably connected to the machine base 1 by a shaft. An embossing swing arm 33 is provided on one side of the edge-rolling worktable 22. There is a transfer channel 11 extending to one side of the cap fixing roller 32; the drive end of the drive mechanism 4 is provided with a drive gear set, the edge rolling transmission mechanism 5 is provided with an edge rolling transmission shaft 51 that is movably connected to the drive gear set and extends to the top of the edge rolling punch head 21, the end of the edge rolling transmission shaft 51 is provided with a punching wheel 52, and one side of the punching wheel 52 is provided with a punching eccentric shaft 53 that is movably connected to the top of the edge rolling punch head 21; the embossing transmission mechanism 6 is movably connected to the drive gear set and makes the embossing roller 31 and the cap fixing roller 32 rotate synchronously, and an embossing cam 34 is movably connected to one side of the drive gear set, and the surface of the embossing cam 34 abuts against the side of the embossing swing arm 33 away from the embossing roller 31.

[0035] This utility model is mainly used for edge rolling, threading, and anti-slip texture processing of metal bottle caps. In this equipment, the machine base 1 serves as a fixed support structure, used to fix and connect the edge rolling mechanism 2, embossing mechanism 3, drive mechanism 4, edge rolling transmission mechanism 5, and embossing transmission mechanism 6, so that all mechanisms form a whole. The drive mechanism 4 is used to drive the stamping roller 52 in the edge rolling mechanism 2 and the embossing roller 31 and bottle cap fixing roller 32 in the embossing mechanism 3 to rotate simultaneously. The edge rolling transmission mechanism 5 and the embossing transmission mechanism 6... The driving mechanism 6 is used to transmit the motion of the driving mechanism 4 to the edge-rolling mechanism 2 and the embossing mechanism 3 respectively. When the edge-rolling mechanism 2 punches the bottle cap blank through the edge-rolling punch head 21, the edge of the bottle cap blank is rolled in the edge-rolling groove 23 to realize the edge-rolling process of the metal bottle cap. The embossing pattern on the surface of the embossing roller 31 and the bottle cap fixing roller 32 in the embossing mechanism 3 includes threads and anti-slip patterns. By rolling the bottle cap blank on the surface of the bottle cap fixing roller 32 through the embossing roller 31, the thread processing and anti-slip pattern processing of the metal bottle cap are realized.

[0036] The working principle of this utility model is as follows: The bottle cap blank to be processed is transported to the surface of the crimping worktable 22 via the bottle cap conveyor belt 12. When the drive mechanism 4 is working, it will cause the drive gear set to rotate, which will drive the stamping wheel 52 to rotate synchronously through the crimping transmission mechanism 5. The stamping eccentric shaft 53 is located off-center on the surface of the stamping wheel 52. The stamping eccentric shaft 53 will perform eccentric movement on the surface of the stamping wheel 52, thereby driving the crimping stamping head 21 to reciprocate in the vertical direction. When the crimping stamping head 21 moves downward, it stamps the bottle cap blank to curl the bottle cap opening and form a crimp. When the crimping stamping head 21 moves upward, the bottle cap blank is pushed into the transfer channel 11 by the feeding mechanism 7. The bottle cap blank is transferred towards the embossing mechanism 3 through the transfer channel 11. When the bottle cap blank is transferred to the embossing mechanism 3, the embossing mechanism 3 is moved towards the embossing mechanism 3. When the bottle cap blank is at the bottom of the transfer channel 11, it is caught by the bottle cap transfer mechanism 8 and pushed to one side of the bottle cap fixing roller 32. Then, the bottle cap blank is pushed by the pusher mechanism 9 and fits onto the surface of the bottle cap fixing roller 32. At this time, the embossing cam 34, driven by the drive mechanism 4, gradually rotates its raised side until it abuts against the surface of the embossing swing arm 33. The embossing swing arm 33 will swing along the shaft connected to the machine base 1 as the pivot, causing the embossing roller 31 to move downward, thereby rolling the bottle cap blank to form threads and anti-slip textures on its surface. As the embossing cam 34 rotates until its raised side no longer abuts against the surface of the embossing swing arm 33, the embossing roller 31 will move upward to complete the embossing process of the bottle cap. The bottle cap fixing roller 32 has ventilation holes that pass through both ends on its axis. The ventilation holes can generate a pushing force on the bottle cap after embossing through the external compressed air to achieve demolding.

[0037] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the drive gear set consists of a drive gear 41 and a transmission gear 42 that are matched with each other. The transmission gear 42 is movably connected to the hemming transmission mechanism 5 and the embossing transmission mechanism 6. The drive mechanism 4 includes the following structure: a drive motor 43, a first pulley 44 at the drive end of the drive motor 43, a second pulley 45 connected to the drive gear 41 by a shaft, and a drive belt 46 that is fitted on the surface of the second pulley 45 and the first pulley 44.

[0038] The driving force generated by the drive motor 43 of this invention is used to drive the edge-rolling mechanism 2, the embossing mechanism 3, the feeding mechanism 7, the bottle cap transfer mechanism 8, and the pushing mechanism 9. The drive motor 43 directly drives the first pulley 44 to rotate, and the second pulley 45 rotates synchronously through the drive belt 46. The second pulley 45 is connected to the drive gear 41 by a shaft, and the drive gear 41 rotates synchronously with the second pulley 45. The transmission gear 42 meshes with the drive gear 41 and is movably connected to the machine base 1 through a shaft, and the transmission gear 42 also rotates synchronously. This invention uses the drive belt 46 and other structures to drive the drive gear set to rotate, so that the drive motor 43 and the drive gear set can be distributed in the vertical direction, which is beneficial to optimizing the space occupied by the equipment. Furthermore, the outer diameter of the first pulley 44 is smaller than that of the second pulley 45, and the outer diameter of the drive gear 41 is smaller than that of the transmission gear 42. By adopting this structure and combining it with the above transmission method to optimize the transmission ratio of the driving force, it is beneficial to achieve a larger torque drive and make it easier for the drive motor to drive the operation of the equipment.

[0039] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the hemming drive shaft 51 is composed of a first hemming shaft 511, a second hemming shaft 512, and a third hemming shaft 513 connected end to end. Hemming drive wheels 514 are provided at the intersection of the first hemming shaft 511 and the second hemming shaft 512, and at the intersection of the second hemming shaft 512 and the third hemming shaft 513. The end of the third hemming shaft 513 is fixedly connected to the stamping wheel 52. A third pulley 54 is provided on one side of the drive gear set. The third pulley 54 and the drive gear 42 are located on the same shaft. A fourth pulley 55 is provided at the end of the first hemming shaft 511. Hemming belt 56 is wound around the surfaces of the third pulley 54 and the fourth pulley 55.

[0040] The first edge-rolling shaft 511, the second edge-rolling shaft 512, and the third edge-rolling shaft 513 of this utility model are all movably connected to the machine base 1 using bearings. Since the drive motor 43 is located at the bottom of the machine base 1 and the edge-rolling mechanism 2 is located at the top of the machine base 1, in order for the drive motor 43 to drive the edge-rolling mechanism 2, the edge-rolling transmission wheel 514 is preferably a helical gear. The driving force generated by the drive motor 43 is transmitted to the stamping wheel 52 in sequence through the horizontally extending first edge-rolling shaft 511, the vertically extending second edge-rolling shaft 512, and the horizontally extending third edge-rolling shaft 513, thereby causing the stamping wheel 52 to rotate and causing the edge-rolling stamping head 21 to reciprocate in the vertical direction to perform edge-rolling processing on the bottle cap blank. In addition, the transmission gear 42 transmits the driving force to the first edge-rolling shaft 511 in sequence through the third pulley 54, the edge-rolling belt 56, and the fourth pulley 55, causing it to rotate. This allows the edge-rolling transmission shaft 51 and the drive gear set to be distributed in the vertical direction, which is beneficial for optimizing the space occupied by the equipment.

[0041] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the embossing transmission mechanism 6 includes the following structure: a first embossing gear 61, which is movably connected to the drive gear set; the first embossing gear 61 meshes with the transmission gear 42; a second embossing gear 62 matching the first embossing gear 61 is provided on one side of the bottle cap fixing roller 32; a third embossing gear 63 matching the first embossing gear 61 is provided on one side of the embossing swing arm 33 via a shaft; and a fourth embossing gear 64 matching the third embossing gear 63 is provided on one side of the embossing roller 31.

[0042] The first embossing gear 61, the second embossing gear 62, and the third embossing gear 63 are all movably connected to the machine base 1 via shafts. The shaft passing through the third embossing gear 63 also passes through the embossing swing arm 33. The fourth embossing gear 64 is movably connected to the embossing swing arm 33 via a shaft. When embossing the bottle cap, the transmission gear 42 transmits driving force to the first embossing gear 61, causing it to rotate. The first embossing gear 61 and the second embossing gear 62 mesh to rotate the bottle cap fixing roller 32. Simultaneously, the first embossing gear 61, the third embossing gear 63, and the fourth embossing gear 64 mesh sequentially to rotate the embossing roller. The embossing roller 31 rotates, causing the bottle cap to rotate relative to the embossing roller 31 during the embossing process, thus fulfilling the necessary conditions for embossing. In addition, the first embossing gear 61 and the third embossing gear 63 are the same size, and the second embossing gear 62 and the fourth embossing gear 64 are the same size but have a smaller outer diameter than the first embossing gear 61. During the meshing transmission of the embossing transmission mechanism 6, the rotation speed of the bottle cap fixing roller 32 and the embossing roller 31 can be increased, so that when the transmission gear 42 rotates once, both the bottle cap fixing roller 32 and the embossing roller 31 can rotate several times, ensuring that the bottle cap surface is stably processed to form threads and anti-slip textures.

[0043] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a bottle cap conveyor belt 12 is provided on one side of the edge-rolling worktable 22. A feeding mechanism 7 is provided between the end of the bottle cap conveyor belt 12 and the edge-rolling worktable 22. The feeding mechanism 7 includes the following structure: a feeding plate 71, a feeding slider 72 at the bottom of the feeding plate 71, a feeding slide rail 73 matching the feeding slider 72 at the top of the edge-rolling worktable 22, a feeding wheel 74 at the top of the edge-rolling worktable 22, a connecting rod 75 movably connected to one side of the feeding wheel 74 by an eccentric shaft, the end of the connecting rod 75 being movably connected to the feeding plate 71, and a feeding drive wheel 76 matching the feeding wheel 74 on the surface of the second edge-rolling shaft 512.

[0044] In this invention, the bottle cap conveyor belt 12 is driven by a motor to rotate, so that the bottle cap blanks on the belt surface are conveyed to one side of the edge-rolling worktable 22. At this time, the second edge-rolling shaft 512 drives the feeding drive wheel 76 to rotate synchronously. The feeding drive wheel 76 and the feeding wheel 74 are preferably meshed gears. The rotating feeding drive wheel 76 causes the feeding wheel 74 to rotate through meshing transmission, so that one end of the connecting rod 75 connected to the feeding wheel 74 moves eccentrically along the feeding wheel 74. At the same time, the bottom of the feeding plate 71 connected to the other end of the connecting rod 75 is provided with a feeding slider 72 and a feeding slide rail. 73. The connecting rod 75 can drive the feeding plate 71 to reciprocate along the feeding slide rail 73. The surface of the feeding plate 71 matches the notch of the bottle cap blank. During the reciprocating motion of the feeding plate 71, the notch will reciprocate between the end of the bottle cap conveyor belt 12 and the bottom of the edge-rolling punch head 21, thereby continuously pushing the bottle cap blank conveyed by the bottle cap conveyor belt 12 to the bottom of the edge-rolling punch head 21 for stamping and edge-rolling processing. The bottle cap blank that has completed the edge-rolling processing will be pushed into the transfer channel by the next bottle cap blank and transferred to the embossing mechanism 3 for embossing processing through the transfer channel.

[0045] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the machine base 1 is equipped with a bottle cap transfer mechanism 8. One end of the bottle cap transfer mechanism 8 near the bottom of the transfer channel 11 is provided with a receiving groove 81, and the other end is provided with a vertically extending transfer groove 82. A transfer wheel 83 is provided on one side of the transfer groove 82, which is movably connected to the drive gear set. The transfer wheel 83 and the transmission gear 42 are located in the same shaft. A transfer eccentric shaft 84 extending into the transfer groove 82 is provided on one side of the transfer wheel 83. A transfer slider 85 is provided at the bottom of the bottle cap transfer mechanism 8. A matching transfer slide rail 86 is provided on one side of the transfer slider 85. The transfer slide rail 86 is fixedly connected to the machine base 1.

[0046] The receiving groove 81 has an upward opening facing the bottom of the transfer channel 11 and is arc-shaped. When the bottle cap blank that has completed the edge rolling process moves to the bottom of the transfer channel, it will be received by the receiving groove 81. At this time, the drive gear set drives the transfer wheel 83 to rotate and causes the transfer eccentric shaft 84 to move eccentrically along the surface of the transfer wheel 83. The receiving groove 81 is fixedly connected to the transfer eccentric shaft 84 by a fixed rod. The transfer eccentric shaft 84 pushes the bottle cap transfer mechanism by moving eccentrically and abutting against the receiving groove 82. 8. The transfer slider 85 moves back and forth along the transfer rail 86. During the reciprocating motion of the bottle cap transfer mechanism 8, the receiving groove 81 will make a circular motion between the bottom of the transfer channel 11 and one side of the bottle cap fixing roller 32. The receiving groove 81 transfers the bottle cap blank that has completed the edge rolling process to one side of the bottle cap fixing roller 32 through the upward semi-circular arc path, and then returns to the bottom of the transfer channel 11 through the downward semi-circular arc path. At the same time, the pusher mechanism 9 fixes the bottle cap blank to the bottle cap fixing roller 32, and then the embossing process can be performed.

[0047] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the embossing mechanism 3 is provided with a pushing mechanism 9 on one side. The pushing mechanism 9 includes the following structure: a pushing slide rail 91, which is fixedly connected to the machine base 1 and internally connected to a pushing slider 92. One end of the pushing slider 92 extends toward the embossing roller 31 and is provided with a pushing disc 93. A semi-circular pushing groove 94 is provided on one side of the pushing slider 92. A pushing wheel 95 is provided on one side of the pushing groove 94. A pushing eccentric shaft 96 extending into the pushing groove 94 is provided on one side of the pushing wheel 95, and a pushing transmission wheel 97 is provided on the other side. A pushing drive wheel 98 matching the pushing transmission wheel 97 is provided on the surface of the second edge-rolling shaft 512.

[0048] When the receiving trough 81 transfers the bottle cap blank to one side of the bottle cap fixing roller 32, the second edge-rolling shaft 512 drives the pusher drive wheel 98 to rotate synchronously. The pusher drive wheel 98 and the pusher transmission wheel 97 are preferably helical gears. The pusher drive wheel 98 and the pusher transmission wheel 97 mesh to drive the pusher wheel 95 to rotate. During the rotation of the pusher wheel 95, the pusher eccentric shaft 96 makes an eccentric movement along the pusher wheel 95. During the eccentric movement of the pusher eccentric shaft 96, it abuts against the pusher through groove 94 and pushes the pusher slider 92 to reciprocate along the pusher slide rail 91, thereby pushing the bottle cap blank in the receiving trough 81 forward through the pusher plate 93. When the pusher slide 92 is temporarily stopped in reciprocating motion, the pusher slide 94 is in semi-circular arc shape and the movement path of the pusher eccentric shaft 96 matches the shape of the pusher slide 94. At this time, the pusher plate 93 just puts the bottle cap blank on the end of the bottle cap fixing roller 32. The pusher slide 92 stops so that the pusher plate 93 presses the bottle cap blank tightly to prevent it from separating from the bottle cap fixing roller 32. After the bottle cap blank completes the embossing process, the pusher slide 92 also stops and moves backward. The bottle cap blank that has completed the embossing process forms a bottle cap with rolled edges, threads, and anti-slip texture. Finally, the bottle cap is demolded to complete the bottle cap processing process.

[0049] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the embossing swing arm 33 has an embossing push rod 35 extending toward the embossing cam 34 at the end away from the embossing roller 31. The end of the embossing push rod 35 is movably connected to an embossing roller 36 that rotates along the surface of the embossing cam 34. When the embossing cam 34 rotates, the embossing roller 36 will rotate at the same time. When the protruding side of the embossing cam 34 abuts against the embossing roller 36, the embossing swing arm 33 can be swung by the transmission through the embossing push rod 35, thereby reducing the friction during the transmission process.

[0050] It should be noted that when the drive mechanism 4 is working, it drives the various processing mechanisms in this equipment to perform the following operations: the feeding mechanism 7 pushes the bottle cap blank to the bottom of the edge-rolling punch head 21; the edge-rolling punch head 21 presses down to perform edge-rolling processing on the bottle cap blank; the bottle cap transfer mechanism 8 transfers the edge-rolled bottle cap blank to one side of the bottle cap fixing roller 32; the pushing mechanism 9 puts the bottle cap blank on one end of the bottle cap fixing roller 32; and the embossing mechanism 3 performs embossing processing on the bottle cap blank, etc. These operations are performed sequentially and continuously. Through the close and coordinated cooperation between the various processing mechanisms, the bottle cap blank is processed into a bottle cap with edge rolling, threads, and anti-slip texture. The above processing only has one drive source, the drive motor 43. The compact and efficient transmission structure enables the normal operation of each mechanism, which is conducive to improving the processing efficiency of bottle caps.

[0051] In summary, this utility model can sequentially perform edge rolling and embossing processes on bottle cap blanks to obtain metal bottle caps with rolled edges, threads, and anti-slip textures. During the processing, the bottle cap blank is fed into the edge rolling mechanism 2 for edge rolling and then transferred to the embossing mechanism 3 for embossing through the cooperation of the drive mechanism 4 and the corresponding transmission mechanism. The entire processing process uses the drive motor 43 as the sole drive source, and the corresponding transmission mechanism enables the processing mechanisms to work synchronously and collaboratively. This can reduce the space occupied by the bottle cap processing equipment and improve the processing efficiency of bottle caps.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
