Description

Technical Field

[0001] The utility model relates to the technical field of automation structures, and specifically relates to a strip feeding and cutting mechanism. Background Art

[0002] In the conventional design of integrated feeding and cutting, the shearing cylinder is directly connected to the cutting knife through a connector. The output force direction of the cylinder is the same as the shearing direction. By replacing the cylinder with a larger bore diameter, a greater shearing force can be obtained to achieve the purpose of cutting the strip. And the feeding mechanism of the strip can only be arranged in the direction perpendicular to the output force direction of the cylinder.

[0003] The patent document with the application publication number CN112510461A discloses a high-speed conveying system of a wireless charger, which specifically discloses that: a cutting cylinder 62 is fixed on the top surface of the top horizontal plate of the U-shaped frame body 61, and a cutting lifting plate and two guide column bodies 632 are arranged below the top horizontal plate. The two ends of the guide column body 632 are respectively fixedly connected to the top surface of the translation plate 64 and the bottom surface of the top horizontal plate of the U-shaped frame body 61. Two guide sleeves 631 corresponding to the positions of the two guide column bodies are fixed on the cutting lifting plate, and the guide sleeves are sleeved on the guide column bodies. The end of the piston rod of the cutting cylinder 62 penetrates through the top horizontal plate of the U-shaped frame body 61 and is fixedly connected to the top surface of the cutting lifting plate 63. An installation block 60 is fixed at one end of the bottom surface of the cutting lifting plate 63 facing the support plate 682, and a cutting knife 69 is fixed on the installation block 60.

[0004] The above patent document can use the cutting cylinder to move down the cutting knife to cut the front ends of multiple copper wires located above the second copper wire positioning through groove, but there are the following problems: the feeding mechanism of the strip can also only be arranged in the direction perpendicular to the output force direction of the cutting cylinder, and the strip feeding mechanism cannot be integrated on the shearing mechanism, and the whole structure will occupy more space. If there are other mechanisms blocking, then the strip feeding mechanism cannot be arranged. Especially in the case of a relatively compact space, even if it can be arranged, it is difficult to maintain, and there are certain limitations in use. Summary of the Utility Model

The second guide rail 113 is movably arranged in the fourth recess 654, the second slider 114 is arranged in the third recess 653, and the second slider 114 is fixedly connected to the second mounting plate 62.

[0058] The abutting member 12 is a roller structure, including a roller 121 and a rotating shaft 122. The rotating shaft 122 is inserted through the roller 121, and both ends of the rotating shaft 122 are respectively connected to the lower ends of the first guide rail 111 and the second guide rail 113.

A through hole (not marked in the figure) is opened on the end surface of one end of the cross beam 21, and a first step portion 211 protrudes inside the through hole. Cover the end surface of one end of the cross beam 21 on the top surface of the mounting seat 13, use a bolt to pass through both the cross beam 21 and the mounting seat 13 at the same time, and make the nut of the bolt abut against the first step portion 211, then the cross beam 21 and the mounting seat 13 can be connected. Of course, in addition to the bolt, other connecting parts such as screws and screw rods can also be used, which are not limited here. A convex block 212 is arranged at the other end of the cross beam 21, and the convex block 212 and the cross beam 21 are in an "L" shape. When the cross beam 21 and the mounting seat 13 are connected, the convex block 212 is arranged in the sixth recess 132. The cutter 22 is installed on the convex block 212.

[0061] Please refer to Figure 1 , Figure 3 , Figures 9 - 14 , in this embodiment, the feeding structure 3 includes a first conveying structure 31 and a second driving structure 32. The first conveying structure 31 is arranged on the top surface of the guiding block 65, a first conveying channel 311 is arranged inside the first conveying structure 31, and the second driving structure 32 drives the material 5 to move in the first conveying channel 311.

[0062] Specifically, the first conveying structure 31 includes a first conveying block 312 and a second conveying block 313. The bottom surface of the first conveying block 312 is connected to the top surface of the second conveying block 313, and the bottom surface of the second conveying block 313 is connected to the top surface of the guiding block 65. A first groove 3121 is recessed in the bottom surface of the first conveying block 312, and the size of the first groove 3121 is basically the same as that of the material 5. The top surface of the second conveying block 313 is a flat surface. When the bottom surface of the first conveying block 312 abuts against the top surface of the second conveying block 313, the above-mentioned first conveying channel 311 is defined. More specifically, the first end of the first conveying block 312 is arranged in a shape similar to a triangle, and the first end of the second conveying block 313 is also arranged in a shape similar to a triangle to adapt to the shape of the second driving structure 32 subsequently.

[0063] It further includes a first elastic member 7. One end of the first elastic member 7 is connected to the top surface of the first conveying block 312, and the other end of the first elastic member 7 is connected to the bottom surface of the mounting seat 13. When the mounting seat 13 moves in the direction of the first conveying block 312, it will always be subjected to the acting force of the first elastic member 7.

[0064] Preferably, in this embodiment, it further includes a second conveying structure 33. The second conveying structure 33 includes a third conveying block 331 and a fourth conveying block 332. The fourth conveying block 332 is spaced apart from the second conveying block 313 by a predetermined distance and is arranged on the top surface of the guiding block 65. The bottom surface of the third conveying block 331 is connected to the top surface of the fourth conveying block 332. A second groove 3311 is recessed in the bottom surface of the third conveying block 331. The top surface of the fourth conveying block 332 is a flat surface. When the bottom surface of the third conveying block 331 abuts against the top surface of the fourth conveying block 332, a second conveying channel 333 is formed.

[0065] The first conveying channel 311 and the second conveying channel 333 are located on the same horizontal plane, that is, the outlet of the second conveying channel 333 and the inlet of the first output channel are located on the same plane. The material 5 first moves in the second conveying channel 333 and then enters the first conveying channel 311 and moves to the shearing position (equivalent to the outlet of the first conveying channel 311). The advantages of this structure are as follows: First, the first conveying channel 311 and the second conveying channel 333 can provide a fixed conveying path for the material 5, enabling the material 5 to maintain a stable direction and position during the transmission process, which helps prevent the material 5 from shifting or twisting during transmission and ensures the smooth transmission of the material 5 along the established route. Second, by designing the groove in the conveying block, the integrated design of the conveying channel is realized, reducing the size and occupied space of the entire strip feeding and cutting mechanism, making the strip feeding and cutting mechanism more compact and efficient. Third, setting the material 5 to move in the first conveying channel 311 and the second conveying channel 333 can, to a certain extent, protect the material 5 from the influence of the external environment (such as dust and other sundries), reducing transmission problems caused by external interference. Fourth, since the first conveying channel 311 is formed by splicing the first conveying block 312 and the second conveying block 313, and the second conveying channel 333 is formed by splicing the third conveying block 331 and the fourth conveying block 332, this splicing design makes the assembly and disassembly of the first conveying channel 311 and the second conveying channel 333 very convenient. When maintenance or replacement of the material 5 is required, the first conveying block 312, the second conveying block 313, the third conveying block 331, and the fourth conveying block 332 can be quickly disassembled for replacement operations, greatly improving the maintenance efficiency.

[0066] Specifically, the second driving structure 32 includes a first driving wheel 321, a first driven wheel 322, a second driving wheel 323, a second driven wheel 324, and a motor 325. A driving structure mounting block 611 is fixedly installed on the outer side surface of the first mounting plate 61. The motor 325 is disposed on the driving structure mounting block 611, and the driving end of the motor 325 passes through the driving structure mounting block 611 and is connected to the first driving wheel 321. The first driving wheel 321 is in transmission connection with the first driven wheel 322 through a conveyor belt 326. The first driven wheel 322 is in transmission connection with the second driving wheel 323 through a first shaft body 327, and the second driven wheel 324 is disposed above the second driving wheel 323.

[0067] A third groove 655 is concavely formed on the top surface of the guiding block 65. The length of the third groove 655 is the interval distance between the aforementioned second conveying block 313 and the fourth conveying block 332. Please refer to Figure 2 , the inner wall of the third groove 655, the inner side surface of the first mounting plate 61, and the inner side surface of the second mounting plate 62 form an installation space 66, and the second driving wheel 323 is disposed in the installation space 66.

[0068] In this embodiment, a fourth groove 612 is concavely formed in the top surface of the first mounting plate 61, and a first fixing block 613 is further provided on the top surface of the first mounting plate 61. The first fixing block 613 is in a "C" shape and cooperates with the fourth groove 612 to form a first moving space 614. A second elastic member 6141 and a first moving block 6142 are disposed in the first moving space 614. One end of the second elastic member 6141 is connected to the first moving block 6142, and the other end of the second elastic member 6141 is connected to a first adjusting member 6143 penetrating through the top of the first fixing block 613.

[0069] Correspondingly, a fifth groove 621 is concavely formed in the top surface of the second mounting plate 62, and a second fixing block 622 is further provided on the top surface of the second mounting plate 62. The second fixing block 622 is in a "C" shape and cooperates with the fifth groove 621 to form a second moving space 623. A third elastic member 6231 and a second moving block 6232 are disposed in the second moving space 623. One end of the third elastic member 6231 is connected to the second moving block 6232, and the other end of the third elastic member 6231 is connected to a second adjusting member 6233 penetrating through the top of the second fixing block 622.

[0070] Specifically, the first adjusting member 6143 and the second adjusting member 6233 are bolts. The first adjusting member 6143 is threadedly connected to the top of the first fixing block 613, and the second adjusting member 6233 is threadedly connected to the top of the second fixing block 622. By the threaded cooperation between the first adjusting member 6143 and the first fixing block 613, and the threaded cooperation between the second adjusting member 6233 and the second fixing block 622, the elastic force of the second elastic member 6141 on the first moving block 6142 and the elastic force of the third elastic member 6231 on the second moving block 6232 can be adjusted.

[0071] The second driven wheel 324 is fixedly connected to the first moving block 6142 and the second moving block 6232 respectively through a second shaft body 328. The bottom surface of the material 5 contacts the second driving wheel 323, and the top surface of the material 5 contacts the second driven wheel 324. The second driving wheel 323 and the second driven wheel 324 cooperate to move the material 5 along the conveying channel to the shearing position. The advantages of this structure are as follows: First, the second driven wheel 324 applies a slight pressing force to the material 5 under the action of gravity to prevent the material 5 from swinging up and down or disengaging from the second driving wheel 323 during transportation. Second, the second driven wheel 324 can appropriately adjust the distance from the second driving wheel 323 under the action of the first moving block 6142 and the second moving block 6232, so as to adapt to materials 5 of different thicknesses.

[0072] Further, please refer to Figure 10, a first gear 3271 is sleeved on the first shaft body 327, and the side surface of the first gear 3271 is connected to the side surface of the second driving wheel 323. A second gear 3281 is sleeved on the second shaft body 328, and the side surface of the second gear 3281 is connected to the side surface of the second driven wheel 324. The first gear 3271 and the second gear 3281 are meshed, so when the second driving wheel 323 rotates, it will drive the second driven wheel 324 to rotate. This synchronous transmission structure can ensure that the material 5 maintains a stable speed and direction during the conveying process. This synchronism can also reduce slipping or deviation caused by uneven friction, and ensure the transmission efficiency.

[0073] Please refer to Figure 2 , in this embodiment, the first driving structure 4 includes a top block 41 and a cylinder 42. The first end of the top block 41 is connected to the cylinder 42, and the second end of the top block 41 is disposed between the mounting seat 13 and the abutting member 12 and contacts the abutting member 12. The top block 41 includes a top plane 411, a front side surface 412, a transition surface 413, an inclined abutting surface 414, and a bottom plane 415 that are connected in sequence. Specifically, please refer to Figure 15 , the second end of the top block 41 is provided with a reference line L1, a reference line L2, a reference line L3, and a reference line L4. The area from the reference line L1 to the reference line L2 defines the front side surface 412, the area from the reference line L2 to the reference line L3 defines the transition surface 413, and the area from the reference line L3 to the reference line L4 defines the inclined abutting surface 414. The top plane 411 and the front side surface 412 are perpendicular to each other. The front side surface 412 and the inclined abutting surface 414 are connected by the transition surface 413. The transition surface 413 is arc-shaped, and the bending degree of the transition surface 413 is basically the same as the bending degree of the abutting member 12, so as to be more smooth when the transition surface 413 and the abutting member 12 are in relative contact and movement. The inclined abutting surface 414 and the bottom plane 415 are arranged at an angle. In this embodiment, the angle between the inclined abutting surface 414 and the bottom plane 415 is 165.2°. This is only an example, and this embodiment is not limited thereto. The cylinder 42 drives the top block 41 to move back and forth in the direction of the abutting member 12. At this time, taking the top block 41 as a reference surface, the abutting member 12 moves on the inclined abutting surface 414.

[0074] Specifically, when the cylinder 42 drives the top block 41 to move in the direction close to the abutting member 12, the abutting member 12 moves from one end of the inclined abutting surface 414 close to the transition surface 413 to one end of the inclined abutting surface 414 close to the bottom plane 415. During this process, since the horizontal plane where the bottom plane 415 is located is below the horizontal plane where the transition surface 413 is located. Therefore, the height of the inclined abutting surface 414 gradually decreases from left to right, resulting in the gradual decrease of the height of the abutting member 12. At this time, the height of the mounting seat 13 will also decrease accordingly and squeeze the first elastic member 7.

[0075] Correspondingly, when the cylinder 42 drives the ejector block 41 to move away from the abutting member 12, the abutting member 12 moves from one end of the inclined abutting surface 414 close to the lower plane 415 to one end of the inclined abutting surface 414 close to the transition surface 413. During this process, since the horizontal plane where the transition surface 413 is located is above the horizontal plane where the lower plane 415 is located. Therefore, the height of the inclined abutting surface 414 gradually increases from right to left. At the same time, under the elastic force of the first elastic member 7, the mounting base 13 will move upward, resulting in a gradual increase in the height of the abutting member 12.

[0076] Therefore, the movement direction of the ejector block 41 is substantially perpendicular to the movement direction of the abutting member 12, and the movement direction of the ejector block 41 is parallel to the feeding direction of the feeding structure 3.

[0077] During the process of the abutting member 12 moving on the inclined abutting surface 414, the inclination angle of the inclined abutting surface 414 determines the stroke of the abutting member 12 moving from the highest position to the lowest position (or from the lowest position to the highest position). That is, the smaller the included angle between the inclined abutting surface 414 and the lower plane 415, the smaller the stroke of the abutting member 12 driving the cutter 22 to move. According to the law of conservation of energy, when the stroke of the cutter 22 decreases, the shearing force of the cutter 22 will be amplified.

[0078] Furthermore, since the abutting member 12 is connected to the mounting base 13 through the guiding member 11, and a cross beam 21 installed with the cutter 22 is further provided on the mounting base 13. When the height of the abutting member 12 changes, it will further drive the height of the cutter 22 to change (that is, the cutter 22 performs a shearing operation). Therefore, by changing the contact position between the abutting member 12 and the inclined abutting surface 414, the distance between one end of the shearing movement structure 1 (i.e., the cutter 22) and the shearing position can be changed.

[0079] Please refer to Figure 6, in this embodiment, the bottom surface of the guiding block 65 is recessed to form a guiding groove 656, and the size of the guiding groove 656 matches the size of the top block 41. Therefore, the top block 41 can move back and forth in the guiding groove 656. The advantages of this structure are as follows: First, it provides a fixed conveying path for the top block 41, enabling the top block 41 to maintain a stable direction and position during movement, which helps prevent the top block 41 from shifting or twisting during movement and ensures the smooth transmission of the top block 41 along the established route. Second, it can protect the top block 41 from the influence of the external environment (such as dust and other debris) to a certain extent and reduce the movement problems caused by external interference. Further, a relatively shallow oil storage groove 657 is recessed along the bottom surface of the guiding groove 656, and the width of the oil storage groove 657 is smaller than the width of the guiding groove 656. Lubricating oil is added to the oil storage groove 657, and its function is that when the top block 41 moves continuously, the lubricating oil will penetrate into the friction area between the top block 41 and the guiding groove 656, thereby reducing the friction and heat generated by the direct contact between the top block 41 and the guiding groove 656, and finally reducing the wear degree of the above two.

[0080] Please refer to Figure 16 , in this embodiment, it further includes a connecting block 8. One end of the connecting block 8 is fixedly connected to the first end of the top block 41, and a connecting space 81 is provided at the other end of the connecting block 8. Two opposite second stepped portions 811 are further protruded in the connecting space 81. The output end of the air cylinder 42 is arranged in the connecting space 81, and one side surface of the air cylinder 42 abuts against the second stepped portion 811. When the air cylinder 42 works, it will push the connecting block 8 to drive the top block 41 to move.

[0081] The working principle of the present utility model is introduced below for better understanding of the present utility model:

[0082] The second driving wheel 323 and the second driven wheel 324 cooperate to move the material 5 along the first conveying channel 311 until it reaches the shearing position (i.e., the outlet of the first conveying channel 311). At this time, the driving cylinder 42 is driven, and the driving end of the cylinder 42 pushes the connecting block 8 to drive the top block 41 to move in the direction of the abutting member 12. Subsequently, the abutting member 12 moves from one end of the inclined abutting surface 414 close to the transition surface 413 to one end of the inclined abutting surface 414 close to the lower plane 415. During this process, since the horizontal plane where the lower plane 415 is located is below the horizontal plane where the transition surface 413 is located, the abutting member 12 will gradually move downward, and drive the mounting seat 13 together with the cutter 22 to move downward (i.e., move the cutter 22 towards the shearing position) so as to perform a shearing operation on the material 5. And during this process, the mounting seat 13 will squeeze the first elastic member 7. When the top block 41 moves in the direction away from the abutting member 12, the abutting member 12 moves from one end of the inclined abutting surface 414 close to the lower plane 415 to one end of the inclined abutting surface 414 close to the transition surface 413. During this process, since the horizontal plane where the transition surface 413 is located is above the horizontal plane where the lower plane 415 is located, and the first elastic member 7 generates an elastic force on the mounting seat 13, the first elastic member 7 will move the mounting seat 13 together with the cutter 22 upward until it returns to the initial position.

[0083] Please refer to Figure 17 , the present utility model also has a second embodiment. The difference between the second embodiment and the first embodiment is that the structure and position of the first driving structure 4 have changed. Specifically:

[0084] In this embodiment, the cylinder 42 is arranged below the abutting member 12, the driving end of the cylinder 42 moves back and forth in the direction of the abutting member 12, and the top block 41 is fixedly connected to the abutting member 12.

[0085] When the top block 41 moves upward under the drive of the cylinder 42, it will drive the abutting member 12 together with the cutter 22 to move upward. Similarly, when the top block 41 moves downward under the drive of the cylinder 42, it will drive the abutting member 12 together with the cutter 22 to move downward. Therefore, in this embodiment, the movement direction of the top block 41 is basically the same as the movement direction of the abutting member 12.

[0086] The other technical features and technical effects of the second embodiment are the same as those of the first embodiment, and will not be elaborated here.
