[0024] The following will be described according to Figure 1 Figure 17 The embodiment of the present application provides a casing production mechanical punching device.

[0025] As Figure 1 Figure 2 ​​As shown, a casing production machine punching device, comprising a conveying belt 2, the conveying belt 2 is supported by a support table 1 in the air, at the same time, a punching roller 4 is arranged on the conveying track of the conveying belt 2, the punching roller 4 is radially arranged with punching needles 25 along its circumference, each row of punching needles 25 is arranged at equal intervals, two groups of tensioning rollers 6 are further arranged on both sides of the punching roller 4, the tensioning rollers 6 and the punching roller 4 are in contact with the belt surface of the conveying belt 2, and further comprising a punching driving assembly arranged on one side of the conveying track of the conveying belt 2, by arranging a hopper 18 at one end of the conveying belt 2, the casing to be punched is put into the hopper 18, and the casing is pulled out through the hopper 18, so that it is pulled to the belt surface of the conveying belt 2, then the punching driving group is used as a driving source, on the one hand, the punching roller 4 and the tensioning roller 6 are driven to rotate relative to the conveying belt 2, the relative roller pressure between the punching roller 4 and the conveying belt 2 and the relative roller pressure between the tensioning roller 6 and the conveying belt 2 are used to make the casing transmit at a constant speed along the belt surface of the conveying belt 2 in a roller pressure conveying mode to carry out the punching process, on the other hand, when the punching roller 4 is driven to rotate, the punching needles 25 rotating to the belt surface of the conveying belt 2 are also driven to intermittently protrude (for example, when the punching needles 25 rotate to the belt surface of the conveying belt 2 in sequence, they can protrude row by row, or in the mode of protruding intermittently by spacing one row or more rows, and then the adjacent two rows of the casing are adjusted by controlling the protruding frequency), and the casing in conveying is punched synchronously.

[0026] In the embodiment, the roller surface of the tensioning roller 6 is provided with two groups of threads 23 divided by a center line, the two groups of threads 23 are arranged in forward and reverse directions, by arranging two groups of threads 23 in forward and reverse directions in the middle part of the roller body of the tensioning roller 6, when the casing passes through the middle part of the tensioning roller 6, the forward and reverse spiral roller conveying of the two groups of threads 23 is used to apply a forward and reverse flattening thrust to the casing, so that the casing can be completely flattened and conveyed for punching, and the punching arrangement uniformity is improved.

[0027] As Figure 1 - Figure 5As shown, the gravity tensioning assembly for exerting displacement on the tensioning roller 6 by the punching roller 4 also includes the telescopic table 3 arranged on both sides of the punching roller 4, and the punching roller 4 is arranged on the lifting end of the telescopic table 3. Meanwhile, the tensioning frame 5 is arranged on both sides of the tensioning roller 6 and is installed on the conveying frame of the transmission belt 2. The tensioning slide table 7 is slidably installed in the tensioning frame 5 and is used for the rotating support of the tensioning roller 6. The first spring seat 8 is arranged on one side of the tensioning slide table 7 and is installed on the tensioning frame 5. The supporting slide table 9 is arranged on the other side of the first spring seat 8. At least one set of traction ropes 20 is arranged between the lifting end of the telescopic table 3 and the supporting slide table 9. The traction ropes 20 are pulled by the first traction wheel set 21 arranged on one side of the supporting slide table 9 and the second traction wheel set 22 arranged on both sides of the telescopic table 3, so that the gravity of the punching roller 4 is converted into the pulling force for the displacement of the tensioning roller 6. The gravity of the punching roller 4 is transmitted to the supporting slide table 9 through the traction ropes 20, so as to exert the compression force on the first spring seat 8. The first spring seat 8 drives the tensioning roller 6 to move away from the punching roller 4, so as to exert the tensioning force on the casing between the tensioning roller 6 and the punching roller 4. Figure 5 As shown, the tensioning roller 6 is kept in the displacement force state in real time by the elastic compression force of the first spring seat 8 acted by the gravity of the punching roller 4, so as to exert the tensioning force on the casing in real time. The tensioning roller 6 drives the casing to be conveyed at a uniform speed along the surface of the transmission belt 2, and at the same time, the tensioning force is exerted on the casing. The casing is conveyed in the tensioning conveying state, so that the casing on the path of the punching roller 4 is kept in the tensioning force state and is punched in the punching process, thereby improving the arrangement accuracy of the punching gap.

[0028] As shown, Figure 1 , Figure 6 - Figure 9To achieve uniform speed of the casing delivery, the punching drive assembly further comprises a first driving pulley 11 arranged at one end of the transmission belt 2 output shaft, a second driving pulley 14 arranged at one end of the punching roller 4 output shaft, a third driving pulley 16 arranged at one end of the tensioning roller 6 output shaft, the first driving pulley 11, the second driving pulley 14, and the third driving pulley 16 have a transmission belt 12 therebetween, and a second traction pulley 17 is further arranged on the support sliding table 9 to provide the wrap angle transmission characteristics between the third driving pulley 16 and the transmission belt 12 (the second traction pulley 17 mounted on the support sliding table 9 moves synchronously with the third driving pulley 16 mounted on the tensioning sliding table 7, the synchronous movement between the two can eliminate the slack of the transmission belt 12 caused during the movement, and under the elastic reset potential of the first spring seat 8, the third driving pulley 16 can also apply static pressure tension to the transmission belt 12 to maintain the transmission stability of the transmission belt 12), and a first traction pulley 15 is further arranged on both sides of the second driving pulley 14 to provide the wrap angle transmission characteristics between the second driving pulley 14 and the transmission belt 12. A driving motor 10 is arranged on one of the roller shafts of the transmission belt 2, and the driving motor 10 is used as a driving source to drive the transmission belt 2 to operate, and the driving source of the transmission belt 2 is then transmitted to the transmission belt 12 to drive the punching roller 4 and the tensioning roller 6 to operate opposite to the transmission belt 2 to achieve the roller pressing uniform speed delivery of the casing along the transmission belt 2.

[0029] It should be noted that the first driving pulley 11 and the roller shaft of the transmission belt 2 have a first spur gear pair 210, the second driving pulley 14 and the punching roller 4 have a second spur gear pair 13 (both ends of the punching roller 4 are provided with a first driving shaft 32 rotatably mounted on the extension end of the extension table 3, and the first driving shaft 32 is connected in transmission with the second driving pulley 14 through the second spur gear pair 13), and the third driving pulley 16 and the tensioning roller 6 have a third spur gear pair 19. By using the spur gear pair, the transmission combination of the transmission belt 2, the punching roller 4, and the tensioning roller 6 can be kept in a synchronous and uniform speed operation state, and the spur gear pair can also realize the opposite operation of the punching roller 4 and the tensioning roller 6 relative to the transmission belt 2. As shown in the arrangement of the feeding bin 18 on the transmission belt 2, when the casing is discharged from the feeding bin 18, the transmission belt 2 rotates counterclockwise to deliver the casing along the belt surface of the transmission belt 2. At this time, the counterclockwise rotation of the transmission belt 2 is converted into the clockwise rotation of the first driving pulley 11 through the first spur gear pair 210, the first driving pulley 11 drives the transmission belt 12 to rotate clockwise, and because the second driving pulley 14 and the third driving pulley 16 are located on the outer side of the transmission belt 12, they generate opposite driving to form a counterclockwise rotation state. At this time, by using the second spur gear pair 13 and the third spur gear pair 19, the combination of the punching roller 4 and the tensioning roller 6 can be kept in a clockwise rotation driving state to operate opposite to the transmission belt 2 to achieve the roller pressing uniform speed delivery of the casing along the belt surface of the transmission belt 2.

Meanwhile, a fixed shaft sleeve 33 is arranged at the middle part of the inner side of the punching roller 4, the fixed shaft sleeve 33 penetrates the first driving shaft 32, and is fixed to the telescopic end of the telescopic table 3 through the fixed table 34. The axial direction of the fixed shaft sleeve 33 is provided with at least one set of second spring seats 39, one end of the second spring seat 39 is provided with a second sliding buckle 3910, and the other end of the second spring seat 39 is provided with a blocking rod 35 which is vertically opposite to the belt surface of the conveying belt 2. Furthermore, the second driving shaft 37 is rotatably arranged in the fixed shaft sleeve 33, the axial direction of the second driving shaft 37 is provided with at least one set of second track grooves 3720 (the second track grooves 3720 are arranged in a spiral structure along the radial direction of the second driving shaft 37), the second sliding buckle 3910 can slide along the second track grooves 3720, and the first track grooves 3710 are arranged at one end of the second driving shaft 37 (the first track grooves 3710 are arranged in a spiral structure along the axial direction of the second driving shaft 37), the telescopic sleeve ring 36 is arranged outside the first track grooves 3710, and the first sliding buckle 3610 which can slide along the first track grooves 3710 is arranged inside the telescopic sleeve ring 36. By controlling the linear movement of the telescopic sleeve ring 36, the linear movement of the telescopic sleeve ring 36 is converted into the rotary movement of the second driving shaft 37 under the cooperation of the first sliding buckle 3610 and the first track grooves 3710, the second driving shaft 37 drives the synchronous rotation of the second track grooves 3720. At this time, the rotary movement of the second driving shaft 37 is converted into the linear movement of the second spring seat 39 under the cooperation of the second track grooves 3720 and the second sliding buckle 3910, the blocking rod 35 is pushed to move to the rotary track of the lifting guide rod 4210, the lifting guide rod 4210 passes through the blocking rod 35 and is blocked to move aside during the rotation process of the punching roller 4 driving the punching needle 25, the punching needle 25 is pushed out to punch the casing, and then when the lifting guide rod 4210 is dislocated from the blocking rod 35, the punched punching needle 25 is reset under the elastic stretching of the third spring seat 42.

[0031] In the embodiment, the punching driving assembly further comprises a rotating disc 26 arranged axially on the first driving shaft 32, and at least one set of tooth rows 27 is arranged circumferentially on the rotating disc 26, the number of each set of tooth rows 27 is different, and a sliding shaft 30 is arranged on one side of the rotating track of the tooth rows 27, wherein one end of the sliding shaft 30 is provided with a tooth buckle 29, the tooth buckle 29 can slide along the tooth rows 27, the sliding shaft 30 is driven to move, the other end of the sliding shaft 30 is provided with an extension shaft 31, the extension shaft 31 is fixedly connected with an extension sleeve ring 36, when the first driving shaft 32 drives the punching roller 4 to rotate, the rotating disc 26 is also driven to rotate, so that the tooth rows 27 on one side of the rotating disc 26 are sequentially dislocated and engaged with the tooth buckle 29, a driving force for driving the sliding shaft 30 to move is generated, then the sliding shaft 30 moves, the extension shaft 31 drives the extension sleeve ring 36 to move, a rotating driving force acting on the second driving shaft 37 is generated, so that the punching needle 25 is sequentially extended in response to the rotation of the punching roller 4, and a synchronous punching process in the casing conveying process is performed.

[0032] It should be noted that, since the number of each set of tooth rows 27 is different, the dislocation and engagement frequency of the tooth buckle 29 is different, so that the punching needle 25 can be extended row by row, or intermittently extended by intervals of one row or more rows, so as to adjust the punching interval between two adjacent rows of casings.

[0033] Further, the second driving shaft 37 is further provided with a spring 38 in the axial direction, after the tooth buckle 29 is completely dislocated from the tooth rows 27 and is not subjected to force, the spring 38 is used for resetting, driving the second driving shaft 37 to rotate and then resetting, on the one hand, the second track groove 3720 is separated from the second slide buckle 3910, the second spring seat 39 drives the stop lever 35 to reset, and on the other hand, the first track groove 3710 acts on the first slide buckle 3610, driving the sliding shaft 30 to drive the tooth buckle 29 to reset, so as to prepare for the next action of pushing out the punching needle 25.

[0034] As Figure 11 Figure 13 ​As shown, in order to realize the extension punching of the punching needle 25 at different frequencies, a lead screw lifting structure 28 is further arranged on the fixed table 34, wherein the lead screw lifting structure 28 comprises a shell 2810 arranged on one side of the sliding shaft 30, and the shell 2810 is located on the fixed table 34. Inside the shell 2810, a lead screw module 2820 is arranged, and a guide sliding sleeve 2830 is arranged on the sleeve sliding table of the lead screw module 2820. The guide sliding sleeve 2830 is slidably connected with the sliding shaft 30. By rotating the lead screw module 2820, the combined lifting movement of the guide sliding sleeve 2830 and the sliding shaft 30 is driven. The height and orientation of the tooth buckle 29 are adjusted, so that the tooth buckle 29 can be aligned with the corresponding tooth row 27 to occur different frequency dislocation state (when the punching roller 4 rotates one round, the tooth row 27 is driven to rotate one round synchronously, and the tooth buckle 29 on the corresponding tooth row 27 occurs dislocation engagement, and then the tooth buckle 29 is moved to the corresponding tooth row 27 to generate driving state at different frequencies, so as to realize the extension punching frequency control of the punching needle 25 when the punching roller 4 rotates one round). Then, the dislocation engagement state of the tooth buckle 29 and the tooth row 27 is utilized to realize the extension punching frequency of the punching needle 25, and the adjustment of the axial spacing of the casing is realized.

[0035] It should be noted that while the sliding shaft 30 is driven to move up and down, the telescopic shaft 31 is arranged in a telescopic manner, so that the sliding shaft 30 before and after adjustment always acts on the telescopic sleeve ring 36.

[0036] As shown in Figure 10 , Figure 16 - Figure 17 In order to realize the adjustment and adaptation of the spacing of the punching needle 25 itself, the punching roller 4 is circumferentially arranged with a punching groove 24 corresponding to the punching needle 25 one by one. The punching groove 24 is arranged with a track frame 40. Inside the track frame 40, track sliding tables 41 are slidably installed in an equal interval split type. The track sliding tables 41 are respectively connected with third spring seats 42 below corresponding to the punching needle 2. At the same time, a third driving shaft 43 is rotatably installed on one side of the track frame 40. Two rows of third track grooves 4310 are oppositely arranged on the third driving shaft 43. The number of the two rows of third track grooves 4310 is the same as that of the track sliding tables 41. Furthermore, an adjustment sleeve ring 44 is arranged on the third driving shaft 43 in an equal interval split type. The adjustment sleeve ring 44 is fixedly connected with the track sliding tables 41. A third sliding buckle 4410 is further arranged inside the adjustment sleeve ring 44. The third sliding buckle 4410 can slide along the third track groove 4310. The third track groove 4310 is an equal interval spiral groove structure. By rotating the third driving shaft 43, the third track groove 4310 on the shaft body of the third driving shaft 43 is rotated. By utilizing the cooperation of the third track groove 4310 and the third sliding buckle 4410, equal interval adjustment of the adjustment sleeve ring 44 is generated. By utilizing the equal interval adjustment characteristics, the punching needle 25 is driven to displace in an equal interval at the center position to adapt to the casing punching work of different diameters.
