Description

Technical Field

[0001] This application relates to the technical field of cap liner production equipment, specifically a welding punching device for cap liner production. Background Technology

[0002] A cap liner is an inner lining component used in hats, usually located on the inner circumference of the cap band. It is generally ring-shaped. Some cap liners are formed by welding the two ends of a long strip of plastic together to form a ring. Other cap liners include a plastic sheath and internal elastic strips. For welding the two ends of the long strip of cap liner, existing cap liner welding and punching equipment is mainly used to process the raw materials of the cap liner, welding the long strip of cap liner material into a ring structure, and punching holes in the ring cap liner to meet the needs of subsequent assembly of the cap liner (such as installing a cap badge).

[0003] However, existing equipment may require a lot of manual operation in processes such as feeding, cutting, pulling, welding and punching of cap wall lining materials. Especially in the welding and punching stages, manual positioning and transfer of cap wall lining are required. It is not possible to weld and punch the cap wall lining in one process. This not only requires multiple machines for processing, but also results in low production efficiency and increased labor costs. Utility Model Content

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0051] Please see Figure 1-11 The embodiments provided by this utility model are as follows: Example

[0052] like Figure 1-9 As shown, a welding punching device for producing cap wall linings includes a processing table 1 for processing cap wall linings, such as... Figure 4 and Figure 5 As shown, a feeding platform 11 is installed on one side of the processing table 1. A feeding assembly 2 is installed on the feeding platform 11. The feeding assembly 2 includes a first feeding roller 21, a second feeding roller 22, a support frame 23, a first servo motor 24, a synchronous belt drive mechanism 25, and gears 26. The support frame 23 is fixedly installed on one side of the feeding platform 11. The first feeding roller 21 and the second feeding roller 22 are both rotatably installed in the support frame 23. The processing table 1 is fixedly installed with the first servo motor 24. The output shaft of the first servo motor 24 is connected to the rotating shaft of the first feeding roller 21 through the synchronous belt drive mechanism 25. Gears 26 are keyed to the side walls of the rotating shafts of the first feeding roller 21 and the second feeding roller 22, and the two gears 26 are meshed together.

[0053] During operation, the first servo motor 24 starts, and its output shaft transmits power to the shaft of the first feeding roller 21 via the synchronous belt transmission mechanism 25, causing the first feeding roller 21 to rotate. Since the gears 26 keyed to one end of the shafts of the first feeding roller 21 and the second feeding roller 22 mesh with each other, the rotation of the first feeding roller 21 will drive the second feeding roller 22 to rotate synchronously. The uncut strip of cap liner is placed on the feeding platform 11, between the first feeding roller 21 and the second feeding roller 22. As the two rollers rotate, the friction between the rollers and the cap liner is used to smoothly feed the cap liner into the subsequent cutting assembly 3.

[0054] Among them, such as Figure 4 As shown, a guide assembly 13 for smoothing the cap wall liner is installed on the top surface of the feeding platform 11. The guide assembly 13 includes two limiting seats 131, a guide rod 132 and two guide plates 133. The two limiting seats 131 are symmetrically installed on the top surface of the feeding platform 11. The two ends of the guide rod 132 are fixedly installed in the two limiting seats 131. The two guide plates 133 are slidably installed on the side wall of the guide rod 132. The two sides of the cap wall liner pass through the gap between the top surface of the feeding platform 11 and the bottom surface of the two guide plates 133.

[0055] Two guide plates 133 are slidably mounted on the side wall of the guide rod 132. The position can be adjusted according to the width of the cap wall liner by means of the loosening and tightening knobs on the guide plates 133. When the long strip of cap wall liner passes through the gap between the top surface of the feeding platform 11 and the bottom surface of the two guide plates 133, the guide plates 133 apply a certain pressure to both sides of the cap wall liner. By using their own weight and the contact friction with the cap wall liner, the uneven cap wall liner is smoothed out. During the cap wall liner conveying process, the guide plates 133 always maintain the constraint and straightening of the cap wall liner, so that the cap wall liner enters the subsequent processing stage in a flat state, avoiding cutting errors or processing quality problems caused by uneven materials.

[0056] like Figure 1 and Figure 7 As shown, a first slide groove 101 is provided on the side wall of the processing table 1. A material pulling assembly 4 is slidably installed in the first slide groove 101. The material pulling assembly 4 includes a first limiting frame 41, a first lead screw linear module 42, a moving seat 43, and a gripper cylinder 44. The first limiting frame 41 is fixedly installed inside the processing table 1. The first lead screw linear module 42 is installed in the first limiting frame 41. The moving seat 43 is installed on the slide of the first lead screw linear module 42. The first lead screw linear module 42 drives the moving seat 43 to slide in the first slide groove 101. The gripper cylinder 44 is installed on the side wall of the moving seat 43.

[0057] The first limiting frame 41 is fixed inside the processing table 1, providing installation support for the first lead screw linear module 42. When the first lead screw linear module 42 is powered on, its slide table drives the moving seat 43 to perform linear reciprocating motion in the first slide groove 101. After the cap liner passes through the cutting assembly 3, the gripper cylinder 44 is activated, using the pneumatic principle of the cylinder to clamp the cap liner through the gripper. Subsequently, the first lead screw linear module 42 drives the moving seat 43 to move, which in turn moves the gripper cylinder 44 and the clamped cap liner, pulling the cap liner out to a certain length. By controlling the moving distance of the first lead screw linear module 42, the required length of cap liner for producing hat linings can be precisely pulled out, achieving precise control of the cap liner length and meeting the needs of producing hat linings of different specifications.

[0058] like Figure 8 and Figure 9 As shown, a second slide groove 102 is provided on the side wall of the processing table 1. A cap wall liner end alignment assembly 5 is slidably installed in the second slide groove 102. The cap wall liner end alignment assembly 5 includes a moving table 51, a support frame 52, two first slide rails 53, a second limiting frame 54, two second lead screw linear modules 55, and two rotary thumb cylinders 56. The bottom surfaces of the moving table 51 are slidably connected to the support frame 52 by the two first slide rails 53 respectively. The support frame 52 is fixedly installed inside the processing table 1. The second limiting frame 54 is fixedly installed on the top surface of the moving table 51. The two second lead screw linear modules 55 are respectively installed in the second limiting frame 54. The two rotary thumb cylinders 56 are respectively installed on the slide seats of the two second lead screw linear modules 55, and the two rotary thumb cylinders 56 are slidably connected in the second slide groove 102.

[0059] The moving table 51 slides on the support frame 52 via two first slide rails 53, achieving horizontal movement. The support frame 52 is fixed inside the processing table 1, providing stable support for the moving table 51. The second limit frame 54 is fixed on the top surface of the moving table 51 and is used to install two second lead screw linear modules 55. When it is necessary to align the ends of the cap wall liner, the two second lead screw linear modules 55 drive the rotary thumb cylinders 56 on their respective slides to move, so that the two rotary thumb cylinders 56 reach the two ends of the long strip of cap wall liner to be cut. The rotary thumb cylinders 56 pneumatically clamp the two ends of the cap wall liner, and then use their own rotation function to rotate the two ends of the cap wall liner to the aligned state, preparing for the subsequent welding process, ensuring that the two ends of the cap wall liner are accurately joined during welding, and improving the welding quality.

[0060] like Figure 4 and Figure 6As shown, a cutting assembly 3 is installed on one side of the feeding platform 11, located on the feeding guide assembly 13. The cutting assembly 3 includes a clamp 31, a first movable frame 32, a cutter 33, a fixed blade 35, a fixed plate 36, a drive frame 37, a third slide rail 38, a slider 39, an eccentric disc 310, a rotating rod 311, and a second servo motor 312. The side walls of the feeding platform 11 are fixedly installed on both sides of the fixed plate 36. The clamp 31 is fixedly installed on the side walls of the fixed plate 36. The two sides of the first movable frame 32 are slidably installed in the clamp 31. The top of the first movable frame 32 is fixedly installed... The first moving frame 32 is integrally formed with a drive frame 37 on its side wall. A third sliding groove 38 is formed around the inside of the drive frame 37. A slider 39 is slidably installed in the third sliding groove 38. A circular groove is formed in the slider 39. An eccentric disk 310 is rotatably connected in the circular groove. A rotating rod 311 is fixedly installed at the eccentric part of the eccentric disk 310. The end of the rotating rod 311 is fixedly installed with the output shaft of the second servo motor 312. The second servo motor 312 is fixedly installed on the inner side wall of the fixed plate 36.

[0061] The fixing plate 36 is fixed to the side wall of the feeding platform 11, providing an installation base for the entire cutting assembly 3. The clamps 31 are installed on both sides of the fixing plate 36 to guide the sliding of the first moving frame 32. After the second servo motor 312 is started, its output shaft drives the rotating rod 311 to rotate. The eccentric disk 310 fixed at the end of the rotating rod 311 rotates eccentrically. The eccentric disk 310 rotates in the circular groove of the slider 39. Due to the eccentric characteristics of the eccentric disk 310, the slider 39 reciprocates in the third sliding groove 38 inside the drive frame 37. The drive frame 37 and the first moving frame 32 are integrally formed, so the slider The sliding of 39 is transmitted to the first moving frame 32 through the drive frame 37, causing the first moving frame 32 to move up and down in the clamp 31. The cutter 33 at the top of the first moving frame 32 moves with the first moving frame 32 and is misaligned with the fixed cutter 35 fixed on the top surface of the fixed plate 36. When the long strip of cap wall liner is located between the cutter 33 and the fixed cutter 35, the cutter 33 moves downward to cooperate with the fixed cutter 35 to cut the cap wall liner to the required length and shape, achieving precise cutting of the cap wall liner. Then, the two rotating thumb cylinders 56 in the cap wall liner end alignment assembly 5 are used to rotate the two ends of the cap wall liner to the alignment state.

[0062] like Figure 2 As shown, a heat pressing assembly 7 is installed on the side wall of the processing table 1. The heat pressing assembly 7 includes a second movable frame 71, a linear guide slide 72, a vibration cylinder 73, and a welding head 74. The second movable frame 71 moves up and down on the side wall of the processing table 1 via the linear guide slide 72. The vibration cylinder 73 is fixedly installed on the top surface of the second movable frame 71, and the welding head 74 is fixedly installed on the bottom end of the vibration cylinder 73.

[0063] When the linear guide slide 72 is powered on, it can drive the second moving frame 71 to move up and down in the vertical direction. The vibration cylinder 73 is fixed on the top surface of the second moving frame 71 and can vibrate the welding head 74, so that the welding head 74 reaches a high-frequency vibration state.

[0064] like Figure 2 and Figure 8 As shown, a support assembly 6 is slidably installed directly below the welding head 74. The welding head 74 is driven by the linear guide slide 72 to contact the top surface of the support assembly 6 to weld the two ends of the cap wall liner. The support assembly 6 includes a pad 61, a mounting platform 62, an electric push rod 63, and a moving rod 64. The mounting platform 62 is fixedly installed inside the processing table 1. The electric push rod 63 is fixedly installed in the mounting platform 62. The telescopic shaft of the electric push rod 63 is fixedly installed with one end of the moving rod 64. The other end of the moving rod 64 is fixedly installed with the tail of the pad 61. The top surface of the pad 61 is correspondingly set with the welding head 74.

[0065] Mounting platform 62 is fixed inside processing platform 1. Electric push rod 63 is installed in mounting platform 62. The telescopic shaft of electric push rod 63 is connected to one end of moving rod 64. The other end of moving rod 64 is fixed to pad 61. After the cut cap wall liner is clamped and rotated by cap wall liner end alignment component 5 and aligned on pad 61, linear guide slide 72 drives welding head 74 to move downward until it contacts the top surface of pad 61, clamping the two ends of cap wall liner. At this time, high-frequency vibrating welding head 74 vibrates the two ends of cap wall liner at high frequency. The heat generated by friction accumulates to form local high temperature, making it difficult for the heat at the two ends of cap wall liner to dissipate in time, causing the contact surface to melt rapidly. When the vibration of the vibrating cylinder 73 stops, the ultrasonic waves of welding head 74 stop, thereby allowing the two ends of cap wall liner to cool and solidify, forming strong molecular chains, so as to realize the welding of strip cap wall liner into ring cap wall liner.

[0066] Among them, such as Figure 9 As shown, a connecting seat 57 is fixedly installed on the side wall of the moving rod 64 by a nut. The top surface of the connecting seat 57 is fixedly installed on the bottom surface of the moving table 51. The electric push rod 63 can control the position of the pad 61. During the process of the pulling assembly 4 pulling the cap wall liner, the electric push rod 63 retracts, so that the pad 61 and the rotating thumb cylinder 56 are put into the processing table 1 to avoid affecting the pulling operation. When the specified length is pulled out, the electric push rod 63 extends, so that the pad 61 and the rotating thumb cylinder 56 are extended from the inside of the processing table 1 for the alignment and welding of the cap wall liner. This realizes the automation and precise control of the welding process, ensuring the quality and efficiency of the cap wall liner welding.

[0067] The connecting seat 57 is fixed to the moving rod 64 by a nut, so that during the extension and retraction of the electric push rod 63, it can simultaneously drive the moving table 51, the cap wall liner end alignment component 5 installed on it, and the pad 61 to move. When the pulling component 4 pulls the cap wall liner, the electric push rod 63 retracts, driving the moving table 51, the pad 61, and the rotary thumb cylinder 56 into the processing table 1 to prevent them from interfering with the pulling process. When the pulling is completed and the cap wall liner needs to be aligned and welded at the end, the electric push rod 63 extends, pushing these components out of the processing table 1, so that the rotary thumb cylinder 56 can clamp and rotate the two ends of the cap wall liner for alignment, and the pad 61 can cooperate with the welding head 74 to complete the welding operation. Example

[0068] like Figure 10 and Figure 11 As shown, a mounting frame 10 is fixedly installed on the side wall of the processing table 1. A punching assembly 9 for punching holes in the cap wall lining is installed on the top side wall of the mounting frame 10. A transfer assembly 8 is installed on the bottom side wall of the mounting frame 10. The transfer assembly 8 includes a linear cylinder 81, a moving frame 82, and pneumatic fingers 84. The linear cylinder 81 is fixedly installed on the bottom outer side of the mounting frame 10. The telescopic shaft of the linear cylinder 81 is fixedly installed on the bottom of the moving frame 82. The top two sides of the moving frame 82 are fixedly installed with pneumatic fingers 84 respectively. Limiting rods 83 are fixedly connected to the bottom two sides of the moving frame 82 respectively. Limiting holes are correspondingly opened on the side wall of the mounting frame 10. The limiting rods 83 are slidably connected in the limiting holes. The top of the moving frame 82 is open.

[0069] The extension and retraction of the shaft of the linear cylinder 81 causes the moving frame 82 to slide along the limiting rod 83 in the limiting hole. When it is necessary to clamp the cap wall liner, the shaft of the linear cylinder 81 extends, causing the moving frame 82 to extend outward. The pneumatic fingers 84 on both sides of the top of the moving frame 82 reach the appropriate position. The pneumatic mechanism inside the pneumatic fingers 84 drives the gripper to close, clamping the cap wall liner. After the welding operation is completed, the shaft of the linear cylinder 81 retracts, causing the moving frame 82 to descend. The gripper of the pneumatic fingers 84 opens, releasing the cap wall liner, so that the cap wall liner can be transferred from the welding station to the punching station, thus completing the welding and punching of the cap wall liner in one operation.

[0070] The punching assembly 9 includes a third servo motor 91, a turntable 92, an eccentric shaft 93, a connecting rod 94, a second moving plate 95, a second slide rail 96, a punching block 97, a punch rod 98, and a pad block 99. The third servo motor 91 is fixedly mounted on the top side wall of the mounting bracket 10. The output shaft of the third servo motor 91 is keyed to the turntable 92. The eccentric shaft 93 is fixedly connected to the side wall of the turntable 92. One end of the connecting rod 94 is sleeved with the eccentric shaft 93, and the other end of the connecting rod 94 is sleeved with the shaft post on the side wall of the second moving plate 95. The side wall of the second moving plate 95 is slidably connected to the mounting bracket 10 through the second slide rail 96. The side wall of the second moving plate 95 is fixedly mounted to the punching block 97. The punch rod 98 is fixedly connected to the bottom surface of the punching block 97. The pad block 99 is fixedly mounted on the side wall of the mounting bracket 10. The punch rod 98 is slidably connected in the punch hole opened in the pad block 99.

[0071] The output shaft of the third servo motor 91 rotates, driving the turntable 92 to rotate synchronously via a key connection. The eccentric shaft 93 on the side wall of the turntable 92 rotates in a circular motion, which in turn drives the connecting rod 94, which is sleeved with the eccentric shaft 93, to move. The other end of the connecting rod 94 is sleeved with the shaft column on the side wall of the second moving plate 95. The movement of the connecting rod 94 converts the circular motion of the eccentric shaft 93 into the reciprocating linear motion of the second moving plate 95 on the slide rail. The second moving plate 95 drives the stamping block 97 and the punch 98 fixed on it to move synchronously. When the punch 98 moves downward, it slides in the punch hole opened on the pad 99. The impact force of the punch 98 is used to punch the cap wall liner located on the pad 99.

[0072] It is worth noting that the pneumatic fingers 84 on the moving frame 82 are located on both sides of the pad 99. The moving frame 82 slides on both sides of the pad 99 through the opening at the top driven by the linear cylinder 81, so that when the moving frame 82 retracts, the annular cap wall liner held by the pneumatic fingers 84 on both sides can be placed between the pad 99 and the stamping block 97 to perform punching.

[0073] Based on the technical solutions of Embodiments 1 and 2 above, the production process of the cap wall liner is as follows:

[0074] S1. Feeding and smoothing of the cap wall liner: The uncut strip of cap wall liner is placed on the feeding platform 11, between the first feeding roller 21 and the second feeding roller 22. The first servo motor 24 is started, and its output shaft transmits power to the rotating shaft of the first feeding roller 21 through the synchronous belt transmission mechanism 25, causing the first feeding roller 21 to rotate. Since the gear 26 connected by the key on one end of the rotating shaft of the first feeding roller 21 and the second feeding roller 22 meshes with each other, the rotation of the first feeding roller 21 will drive the second feeding roller 22 to rotate synchronously. Relying on the friction between the roller and the cap wall liner, the cap wall liner is smoothly fed into the subsequent stage. At the same time, the two sides of the cap wall liner pass through the gap between the top surface of the feeding platform 11 and the bottom surface of the two guide plates 133. The two guide plates 133 can be adjusted according to the width of the cap wall liner. Using their own weight and the contact friction with the cap wall liner, the uneven cap wall liner is smoothed, so that the cap wall liner enters the subsequent processing stage in a flat state.

[0075] S2. Pulling the cap liner: After the cap liner passes through the cutting assembly 3, the gripper cylinder 44 is activated. Using pneumatic principle, the gripper clamps the cap liner. The first lead screw linear module 42 is powered on, and its slide table drives the moving seat 43 to make linear reciprocating motion in the first slide groove 101. The moving seat 43 moves, which in turn drives the gripper cylinder 44 and the clamped cap liner to move. By controlling the moving distance of the first lead screw linear module 42, the required length of cap liner for the production of the cap liner is precisely pulled out.

[0076] S3. End alignment and clamping of cap wall liner: The electric push rod 63 retracts, allowing the pad 61 and the rotary thumb cylinder 56 to be stored in the processing table 1, avoiding interference with the material pulling operation. After the material pulling is completed, the electric push rod 63 extends, extending the pad 61 and the rotary thumb cylinder 56 from inside the processing table 1. The two second lead screw linear modules 55 drive the rotary thumb cylinders 56 on their respective slides to move, so that the two rotary thumb cylinders 56 reach the two ends of the long strip of cap wall liner to be cut. The rotary thumb cylinders 56 pneumatically clamp the two ends of the cap wall liner and use their own rotation function to rotate the two ends of the cap wall liner to an aligned state, preparing for the subsequent welding process.

[0077] S4. Cutting of the cap wall liner: The cap wall liner is fed into the cutting assembly 3. In the cutting assembly 3, the fixing plate 36 is fixed to the side wall of the feeding platform 11. After the second servo motor 312 is started, its output shaft drives the rotating rod 311 to rotate. The eccentric disk 310 fixed at the end of the rotating rod 311 rotates eccentrically. The eccentric disk 310 rotates in the circular groove of the slider 39, causing the slider 39 to slide back and forth in the third sliding groove 38 inside the drive frame 37. The drive frame 37 is integrally formed with the first moving frame 32. Therefore, the sliding of the slider 39 is transmitted to the first moving frame 32 through the drive frame 37, so that the first moving frame 32 moves up and down in the clamp 31. The cutter 33 at the top of the first moving frame 32 moves with the first moving frame 32 and is misaligned with the fixed blade 35 fixed on the top surface of the fixing plate 36, cutting the cap wall liner between the cutter 33 and the fixed blade 35 into the required length and shape.

[0078] S5. Welding of the joints at both ends of the cap wall liner: The linear guide slide 72 drives the welding head 74 to move downwards until it contacts the top surface of the pad 61, clamping both ends of the cap wall liner. The oscillating cylinder 73 vibrates the welding head 74, making the welding head 74 reach a high-frequency vibration state. The high-frequency vibrating welding head 74 vibrates the two ends of the cap wall liner at high frequency. The heat generated by friction accumulates to form a local high temperature, causing the contact surface at both ends of the cap wall liner to melt rapidly. When the oscillating cylinder 73 stops vibrating, the ultrasonic waves of the welding head 74 stop, and the two ends of the cap wall liner cool and solidify, forming a strong molecular chain, thus realizing the welding of the strip cap wall liner into a ring cap wall liner.

[0079] S6. Transfer and punching of cap wall lining:

[0080] Transfer: The linear cylinder 81 extends its shaft, driving the moving frame 82 to slide along the limiting rod 83 in the limiting hole. The pneumatic fingers 84 on both sides of the top of the moving frame 82 reach the appropriate position. The pneumatic mechanism inside the pneumatic fingers 84 drives the gripper to close, clamping the welded cap wall liner. The linear cylinder 81 retracts its shaft, driving the moving frame 82 to descend, transferring the cap wall liner from the welding station to the punching station. The gripper of the pneumatic fingers 84 opens, releasing the cap wall liner, so that the cap wall liner is placed between the pad block 99 and the stamping block 97.

[0081] Punching: The output shaft of the third servo motor 91 rotates, which drives the turntable 92 to rotate synchronously through a key connection. The eccentric shaft 93 on the side wall of the turntable 92 rotates in a circular motion with the turntable 92, which drives the connecting rod 94 to move. The circular motion of the eccentric shaft 93 is converted into the reciprocating linear motion of the second moving plate 95 on the slide rail. The second moving plate 95 drives the punching block 97 and punch rod 98 fixed on it to move synchronously. When the punch rod 98 moves downward, it slides in the punch hole opened on the pad 99 to punch the cap wall liner located on the pad 99, thus completing the production of the cap wall liner.
