[0002] The knock material machine is a device for processing granular and blocky materials in industrial production, which mainly realizes the crushing, screening or conveying of materials through impact and grinding. The knock material machine counting device is a key auxiliary equipment matched with the knock material machine, which is used for real-time statistics of the number of materials processed (or conveyed) by the knock material machine, and is a core tool for production measurement, quality control and capacity management. The existing knock material machine counting device generally sets a sensor module to sense the passing signal of the material, and converts the "material existence" into an electrical signal (such as a light shielding or weight change trigger signal), so as to accurately measure and provide data support for production efficiency improvement and cost control. However, when the knock material machine processes rod-shaped, strip-shaped or tubular materials with strict length requirements, it is often difficult to separate long and short materials synchronously during the counting process. Such materials usually have length deviation due to production process (such as cutting and molding), and the downstream application has a clear standard for the consistency of the material length.

[0023] As Figures 1-7As shown, it shows a kind of knock material machine counting device in an embodiment of the present disclosure, applied to knock material machine, knock material machine is used to cut tubular material 3 into different lengths, including installation frame 1, further including material guide channel 2, conveying mechanism, counting mechanism and material distribution assembly; As Figure 1 Shown, one end of material guide channel 2 is fixedly connected on installation frame 1, for guiding material 3 after being cut by knock material machine into installation frame 1, in order to guide material 3 to transfer to conveying belt 6 and between rubber roller 15 on two clamping frames 13, one end of material guide channel 2 is communicated with the discharge end of knock material machine, the inner side wall of one end of material guide channel 2 is set as arc, it needs to be added that material 3 is cut through the discharge end of knock material machine into material guide channel 2, and after transferring from one end to the other end of material guide channel 2, it is on conveying belt 6; As Figure 1 And Figure 5 Shown, conveying mechanism is arranged in installation frame 1, for receiving material 3 and conveying material 3, in order to can convey material 3, conveying mechanism includes driving shaft 4, driving roller 5, conveying belt 6 and driving motor 7, two driving shafts 4 are rotatably arranged in installation frame 1, driving roller 5 is sleeved on driving shaft 4 and is coaxially fixedly connected with driving roller 5, conveying belt 6 is packed in two driving rollers 5, driving motor 7 is installed on installation frame 1, the output end of driving motor 7 is coaxially fixedly connected with one end of one driving shaft 4, by starting driving motor 7, the output end of driving motor 7 rotates and drives one driving shaft 4 to rotate, the driving shaft 4 rotates and drives the driving roller 5 connected with it to rotate, driving roller 5 drives conveying belt 6 to move on two driving rollers 5, so that another driving roller 5 and another driving shaft 4 rotate, when material 3 transfers to conveying belt 6, material 3 is conveyed from one end of conveying belt 6 to the other end by the driving of driving motor 7; As Figure 2 、 Figure 3 、 Figure 6 And Figure 7As shown, the counting mechanism is arranged on the mounting frame 1 and used for counting the number of materials 3. In order to count the materials 3 passing through the conveying mechanism, the counting mechanism comprises a limiting mechanism, a fixing frame 8, a connecting plate 9, a mounting plate 10 and a photoelectric sensor 11. The limiting mechanism is arranged in the mounting frame 1 and used for clamping the materials 3. In order to abut and clamp the materials 3, the materials 3 are kept at the center of the conveying belt 6 and kept in a horizontal state, so as to avoid the materials 3 being conveyed in an inclined state on the conveying belt 6. The limiting mechanism comprises a first electric cylinder 12, a clamping frame 13, a rotating shaft 14 and a rubber roller 15. The first electric cylinder 12 is arranged at two ends of the mounting frame 1. The output end of the first electric cylinder 12 penetrates through the side wall of the mounting frame 1 and extends. The two first electric cylinders 12 are of the same type. The output end of the first electric cylinder 12 is fixedly connected with the clamping frame 13. The clamping frame 13 is in sliding fit with the conveying belt 6. A plurality of rotating shafts 14 are rotatably arranged in the clamping frame 13. The rubber roller 15 is coaxially and fixedly connected with the rotating shaft 14 and is sleeved on the rotating shaft 14. In order to stably clamp the materials 3 and convey the materials 3 in cooperation with the conveying mechanism, the rubber roller 15 is provided with a recess 23 matched with the materials 3. The midpoint of the axis of the rubber roller 15 is on the same horizontal line as the axis of the materials 3. The plurality of rubber rollers 15 are uniformly arranged in the clamping frame 13. By simultaneously starting the two first electric cylinders 12, the output ends of the two first electric cylinders 12 respectively push the two clamping frames 13 to move towards each other. The clamping part drives the rotating shaft 14 and the rubber roller 15 to move. The plurality of rubber rollers 15 on the two clamping frames 13 abut and clamp the materials 3 and adjust the orientation of the materials 3, so that the materials 3 keep parallel to the conveying belt 6 and are conveyed on the conveying belt 6 in cooperation with the driving of the conveying mechanism. The plurality of rubber rollers 15 rotate under the support of the rotating shaft 14, so that the materials 3 are conveyed in the center of the conveying belt 6, thereby avoiding affecting the conveying of the materials 3. The fixing frame 8 is fixedly connected with the mounting frame 1 and is above the limiting mechanism. One end of the connecting plate 9 is fixedly connected with one end of the fixing frame 8. One end of the mounting plate 10 is fixedly connected with the other end of the connecting plate 9. The other end of the mounting plate 10 is symmetrically provided with two photoelectric sensors 11. In order to measure the length of the materials 3 in cooperation with the control panel 16, the two photoelectric sensors 11 are on the same straight line and are at the center position below the fixing frame 8. When the materials 3 are conveyed directly below the two photoelectric sensors 11 in cooperation with the conveying mechanism and the limiting mechanism, the two photoelectric sensors 11 sequentially sense the passing of the materials 3. As Figure 3 and Figure 4As shown, the material separating component is mounted on the mounting frame 1 and is used in conjunction with the counting mechanism to separate materials 3 that do not meet the requirements. In order to distinguish materials 3 whose cutting length does not meet the requirements, the material separating component includes a control panel 16, a second electric cylinder 17, a pusher plate 18, and a discharge component. The control panel 16 is mounted on the mounting frame 1, and both photoelectric sensors 11 are electrically connected to the control panel 16. When material 3 passes through, the photoelectric sensors 11 receive a signal and transmit it to the control panel 16 to record the quantity of material 3. By recording the time difference between the two photoelectric sensors 11 when one end of material 3 passes through, and in conjunction with the constant speed of the conveyor belt 6 driven by the drive motor 7, the quantity of material 3 can be calculated. The length of the material 3 is determined by the length of the material 3. The second electric cylinder 17 is installed on the mounting frame 1. The output end of the second electric cylinder 17 extends through the side wall of the mounting frame 1. The second electric cylinder 17 is electrically connected to the control panel 16. When the length of the material 3 calculated by the control panel 16 does not meet the requirements (the error with the required length is too large), the control panel 16 sends a signal to control the second electric cylinder 17 to start. The output end of the second electric cylinder 17 pushes the pusher plate 18 toward the material 3 and pushes the material 3 to the discharge port 20. The material 3 is transferred out of the mounting frame 1 through the discharge port 20 under the drive of the conveying mechanism and the push of the second electric cylinder 17. One end of the pusher plate 18 is fixedly connected to the output end of the second electric cylinder 17. It should be added that after material 3 passes through the two photoelectric sensors 11, material 3 "detaches" from the clamping of the rubber roller 15 and is located on one side of the pusher plate 18. like Figure 3 As shown, the discharge component is installed on the mounting frame 1 to transfer the sorted material 3 out of the mounting frame 1. To transfer the material 3 out of the mounting frame 1, the discharge component includes a first discharge rack 19, a discharge port 20, a first discharge plate 21, and a second discharge plate 22. The first discharge rack 19 is fixedly connected to one end of the mounting frame 1. The mounting frame 1 has a discharge port 20. To transfer the material 3 into the first discharge rack 19 and prevent the material 3 from being difficult to transfer out of the mounting frame 1 under the conveyor belt 6, the discharge port 20... The length of the material is greater than the length of the material 3 and is located on one side of the clamping frame 13. The first discharge frame 19 is inclinedly provided with a first discharge plate 21 and a second discharge plate 22 is inclinedly provided in the mounting frame 1. One end of the second discharge plate 22 is slidably engaged with the conveyor belt 6. When the material 3 that does not meet the requirements is pushed out of the mounting frame 1 by the second electric cylinder 17, the material 3 is transferred to the corresponding discharge position along the first discharge plate 21, while the material 3 that meets the requirements will be directly transferred to the corresponding discharge position along the second discharge plate 22 by the conveyor belt 6. Working principle: after the material 3 is cut, it enters the guide channel 2 through the discharge end of the material knocking machine, and is transferred to the conveying belt 6 through the guide channel 2. By starting the driving motor 7, the output end of the driving motor 7 drives a driving shaft 4 to rotate, which drives the driving roller 5 connected thereto to rotate, and the driving roller 5 drives the conveying belt 6 to move on the two driving rollers 5, so that the other driving roller 5 and the other driving shaft 4 rotate. When the material 3 is transferred to the conveying belt 6, the material 3 is conveyed from one end of the conveying belt 6 to the other end by the driving of the driving motor 7; By simultaneously starting the two first electric cylinders 12, the output ends of the two first electric cylinders 12 respectively push the two clamping frames 13 to move towards each other, the clamping pieces drive the shaft 14 and the rubber rollers 15 to move, the multiple rubber rollers 15 on the two clamping frames 13 abut and clamp the material 3, and the orientation of the material 3 is adjusted, so that the material 3 remains parallel to the conveying belt 6 and cooperates with the driving of the conveying mechanism. The material 3 is horizontally conveyed by the multiple rubber rollers 15 rotating under the support of the shaft 14, so that the material 3 is horizontally conveyed at the center position of the conveying belt 6, avoiding affecting the conveying of the material 3. When the material 3 is conveyed directly below the two photoelectric sensors 11 under the cooperation of the conveying mechanism and the limiting mechanism, the two photoelectric sensors 11 sequentially sense the passing of the material 3. The photoelectric sensor 11 receives the signal and transmits it to the control panel 16, records the number of the material 3, and calculates the length of the material 3 by recording the time difference of one end of the material 3 passing through the two photoelectric sensors 11, and cooperating with the constant speed of the driving motor 7 driving the conveying belt 6. When the length of the material 3 calculated by the control panel 16 does not meet the requirements (the error with the required length is too large), the control panel 16 sends a signal to control the second electric cylinder 17 to start, and the output end of the second electric cylinder 17 pushes the material pushing plate 18 to move towards the material 3, and pushes the material 3 to the discharge port 20. After the material 3 is transferred out of the installation frame 1 by the driving of the conveying mechanism and the pushing of the second electric cylinder 17, it is transferred along the first discharge plate 21 to the corresponding discharging position, while the material 3 meeting the requirements is directly conveyed along the second discharge plate 22 to the corresponding discharging position.
