In the drawings, the X axis is horizontal, also the left-right direction; the Y axis is longitudinal, also the front-back direction, the arrow direction of the Y axis is the coil conveying direction, also the front; the Z axis is vertical, also the up-down direction.

[0038] This potting machine includes a material reel 44, a traction mechanism, a molding mechanism 45, a potting mechanism 46, and a driving mechanism for driving the molding mechanism and the potting mechanism to move forward and backward synchronously; the traction mechanism includes a front traction component 1 and a rear traction component 2, the front traction component and the rear traction component synchronously and continuously convey the coil, and the molding mechanism 45 and the potting mechanism 46 are sequentially arranged between the rear traction mechanism 2 and the front traction mechanism 1 to move. When the molding mechanism and the potting mechanism are in operation, the driving mechanism drives the molding mechanism and the potting mechanism to move forward synchronously with the coil, that is, the coil is formed and potted during the traction process; after the operation is completed, the driving mechanism drives the molding mechanism and the potting mechanism to quickly retreat and reset, so that there is no need to provide additional time for the molding and potting operations, which greatly improves the production efficiency. The sheet material coil is formed and potted to become a finished product coil. The sheet material coil and the finished product coil are the same continuous coil. The sheet material coil is placed on the material reel 44. The rear traction component pulls the sheet material coil, and the front traction component pulls the finished product coil. The two are pulled synchronously to increase the traction force and reduce the stretching problem of the coil.

[0039] The molding mechanism 45 is connected to the potting mechanism 46, and the two are slidably arranged on the first guide rail 50, and the first guide rail is longitudinally arranged on the frame 30; the driving mechanism includes a screw 47, a nut 48 and a first motor 51 that drives the screw to rotate, the first motor is connected to the controller, the nut 48 is threadedly connected to the screw 47, the screw is rotatably arranged on the frame and arranged parallel to the first guide rail, and the nut is connected to the molding mechanism or / and the potting mechanism. The first motor drives the screw to rotate, driving the nut to move longitudinally, so that the molding mechanism and the potting mechanism move forward or backward along the first guide rail, and the moving speed of the molding mechanism and the potting mechanism is achieved by controlling the rotation speed of the first motor by the controller.

[0040] The front traction component 1 includes a vertically arranged rotating roller 6, an upper pressing wheel 7 and a lower pressing wheel 8. The rotating roller 6 is connected to the second motor 10. The circumferential side surface of the rotating roller includes an upper pressing surface 3, a lower pressing surface 5 and a yield groove 4 arranged between the upper pressing surface and the lower pressing surface. The upper pressing wheel 7 and the lower pressing wheel 8 are rotated and pressed with the upper pressing surface 3 and the lower pressing surface 5 of the rotating roller respectively to bite the upper and lower ends of the coiled material therebetween. When the second motor drives the rotating roller 6 to rotate, the rotating roller and the upper and lower pressing wheels rotate in opposite directions to transport the coiled material forward. The second motor 10 drives the rotating roller 6 to rotate at a constant speed, and the finished coiled material moves forward at a constant speed, thereby realizing continuous transportation of the coiled material. The sealing edge 41 of the finished coil is gripped by the upper pressing wheel 7 and the upper pressing surface 3, the bottom sealing edge 43 of the finished coil is gripped by the lower pressing wheel 8 and the lower pressing surface 5, the protruding forming part 42 of the finished coil corresponds to the clearance groove 5, and the clearance groove accommodates the protruding forming part to prevent the forming part from being rubbed and squeezed, and maintain a complete forming state. The rear traction component 2 can also adopt the structure of the above-mentioned front traction component 1. Since the rear traction component pulls the sheet coil, the rear traction component 2 preferably adopts two traction rollers 22 that are pressed together, and one of the traction rollers is connected to the third motor 23. The two traction rollers rotate in opposite directions to achieve traction of the sheet coil, and the contact area between the traction roller 22 and the sheet coil is large, and the traction is more stable; in addition, the positions of the front traction component and the rear traction component on the frame are far apart, and two motors are used to drive, which is not only easy to install, but also has a more streamlined structure.

[0041] The upper pressing wheel 7 is rotatably arranged on the bracket, and there are several upper pressing wheels, which are arranged in an arc shape along the upper pressing surface, so that the coil is in contact with the upper pressing surface 3, increasing the contact area; in the figure, there are three upper pressing wheels 7 and three lower pressing wheels 8, which are evenly installed on the bracket, and the contact area between the coil and the rotating roller is increased by the several upper pressing wheels and the lower pressing wheels, and the traction force on the coil is increased, so that the coil moves forward more stably and avoids slipping during traction. In order to facilitate the adjustment of the height position of the upper pressing wheel 7 and the lower pressing wheel 8, the bracket includes a column 9, an upper mounting plate 15 and a lower mounting plate 16. The upper mounting plate and the lower mounting plate are installed on the column, and there is a gap between the upper mounting plate, the lower mounting plate and the rotating roller 6, so that the coil will not contact the mounting plate. The side of the upper mounting plate 15 facing the rotating roller is provided with a first arc segment 21 matching the upper pressing surface, and the side of the lower mounting plate facing the rotating roller is provided with a second arc segment 24 matching the lower pressing surface. The first arc segment and the second arc segment correspond to each other up and down. The upper pressing wheel 7 is rotatably mounted on the first arc segment 21, and the lower pressing wheel 8 is rotatably mounted on the second arc segment 24. The first arc segment and the second arc segment allow a plurality of upper pressing wheels and a plurality of lower pressing wheels to be arranged in an arc shape and pressed with the upper pressing surface and the lower pressing surface of the rotating roller 6. The upper pressing wheel 7 is rotatably connected to a central shaft 18, which is mounted on the upper mounting plate and does not rotate. The upper pressing wheel is coaxially connected to the central shaft through a bearing, and the upper pressing wheel rotates relative to the central shaft. The first arc segment is horizontally provided with a receiving cavity 19 for receiving the upper pressing wheel, and vertically provided with a mounting hole 20 for inserting the central shaft, the mounting hole passes through the receiving cavity from top to bottom, the upper pressing wheel 7 is placed in the receiving cavity 19, and the upper and lower ends of the central shaft 18 are placed in the mounting hole 20. Both upper and lower ends of the central shaft are equipped with a pressing rod 17 for adjusting the pressure between the upper pressing wheel and the upper pressing surface, the pressing rod is horizontally arranged and threadedly connected to the upper mounting plate 15, the pressing rod extends into the mounting hole to press the central shaft 18, so that the upper pressing wheel is pressed against the upper pressing surface of the rotating roller, and the pressure between the upper pressing wheel and the rotating roller is adjusted by adjusting the depth of the pressing rod. When the coil is thin or the pressure on the coil is insufficient, the push rod 17 is rotated to make it penetrate into the mounting hole 20, press the central axis 18, and increase the pressure between the upper pressing wheel and the upper pressing surface; when the coil is thick or the pressure on the coil is too large, the push rod is rotated in the opposite direction to make it retreat, reducing the pressure between the upper pressing wheel and the upper pressing surface, so as to adjust the pressure on the coil to achieve the best traction effect. The lower pressing wheel can also adopt the above-mentioned installation structure.

[0042] The specifications of the coil and the height of the coil on the frame will vary, in order to adapt to the traction of different coils. The rotating roller 6 includes an outer cylinder 11 and an inner shaft 12, the outer cylinder is sleeved outside the inner shaft, the inner shaft is equivalent to the rotating shaft of the rotating roller, the outer cylinder 11 and the inner shaft 12 are circumferentially linked, that is, the rotation of the inner shaft drives the outer cylinder to rotate, and the inner shaft is connected to the second motor 10. The outer cylinder 11 is axially movable relative to the inner shaft 12, that is, the outer cylinder can be raised and lowered relative to the inner shaft. The second motor 10 drives the inner shaft 12 to rotate, so that the rotating roller 6 rotates; if the height position of the coil changes, the outer cylinder 11 moves axially relative to the inner shaft 12, so that the upper and lower pressing surfaces and the clearance groove on the outer cylinder correspond to the height of the coil. See the attached figure, specifically, the circumferential side of the inner shaft is provided with a limiting groove, the inner wall of the outer cylinder 11 is provided with a convex block 14, the convex block is placed in the limiting groove, and the outer cylinder 11 is linked with the inner shaft 12 through the convex block 14. The outer cylinder is connected with a screw 13, which is vertically arranged and threadedly connected to the inner shaft 12. When the screw is rotated, the inner shaft cannot move axially, that is, cannot be lifted or lowered, so that the screw is lifted or lowered relative to the inner shaft. When the screw 13 is lifted or lowered, the outer cylinder 12 connected to the screw is lifted or lowered relative to the inner shaft. The upper mounting plate 15 and the lower mounting plate 16 are movably mounted on the column 9, and the upper mounting plate and the lower mounting plate are locked on the column by locking bolts. When the height position of the coil changes, the height of the upper pressing wheel and the lower pressing wheel is changed accordingly by moving the upper mounting plate and the lower mounting plate to meet the needs of the coil.

[0043] The filling machine also includes a cutting mechanism, and a continuous finished coil material storage mechanism is provided between the cutting mechanism and the front traction component. The finished coil material storage mechanism includes a storage station for storing finished coil materials and a feeding component 27 for conveying finished coil materials to the cutting mechanism, and the feeding component intermittently conveys finished coil materials; the front traction mechanism 1 continuously conveys finished coil materials, and the finished coil materials are stored in the storage station, and the feeding component 27 conveys the stored finished coil materials to the cutting mechanism 26, so that the length of the finished coil materials conveyed by the feeding component to the cutting mechanism will not be affected by the operation of the filling mechanism and the conveying of the traction mechanism, so that the feeding component 27 can accurately convey the fixed length, and accurate fixed-length conveying means accurate cutting by the cutting mechanism.

[0044] If the finished coils at the storage station are in a relaxed state, it will affect the accuracy of the fixed-length conveying of the feeding component. In order to keep the finished coils at the storage station taut, the storage station is provided with a storage component, which includes a tensioning roller 29 and an external force member 36. The tensioning roller is vertically arranged and rotatably arranged on a slide 37. The slide is slidably arranged on a guide rail 38, and the guide rail is horizontally arranged on a frame 30. The external force member 36 is connected to the tensioning roller 29. The finished coils are wound around the tensioning roller. The tensioning roller 29 is simultaneously acted upon by the finished coils and the external force member 36. The force of the finished coils on the tensioning roller comes from the feeding component 27. The external force member can be a tension spring, which has low cost and is easy to install. The feeding component pulls the finished coils, and the tension of the finished coils on the tensioning roller is opposite to the tension of the tension spring on the tensioning roller. See attached. Figure 3 The tension of the finished coil on the tension roller is in direction A, and the tension of the tension spring on the tension roller is in direction B. When the feeding component 27 delivers the finished coil to the cutting mechanism and the finished coil at the storage station decreases, the tension of the finished coil causes the tension roller to move along the guide rail 38 in the traction direction, and the tension spring 36 is stretched; when the amount of finished coil at the storage station increases, the tension spring pulls the tension roller to move in the opposite direction along the guide rail, so that the finished coil wound on the tension roller remains tensioned to avoid relaxation. In order to keep the finished coil stable during the traction process and prevent it from moving up and down, the storage component also includes a limiter, which includes an upper baffle 31 and a lower baffle 32, which are installed on two columns 33. The distance between the upper baffle and the lower baffle matches the height of the finished coil, and the upper baffle, the lower baffle and the two columns form a cavity 39 for the finished coil to pass through. The finished coil passes through the cavity and bypasses the tensioning roller 29 and then passes out of the cavity into the feeding component 27. The limiter limits the upper and lower positions of the finished coil during transportation to prevent it from shifting, further improving the accuracy of fixed-length feeding. See attached Figure 8 The finished coil has a protruding forming part 42, and using an ordinary roller with a flat surface will cause the forming part to be squeezed. The circumferential side of the tensioning roller 29 is provided with a clearance groove 35 corresponding to the forming part of the finished coil, and the top sealing edge 41 and the bottom sealing edge 43 of the finished coil are respectively in contact with the side 34 above and below the clearance groove, so that the finished coil is wrapped outside the tensioning roller 29 and the top sealing edge and the bottom sealing edge are both in contact with the side 34 of the tensioning roller, while preventing the forming part from being squeezed.

[0045] The feeding component 27 pulls the finished coil material, and the feeding component can also adopt the structure of the above-mentioned front traction component 1. The intermittent conveying speed of the feeding component 27 is not slower than the conveying speed of the traction mechanism 1, that is, the finished coil material conveyed by the traction mechanism to the storage station can be consumed by the cutting mechanism 26, so that the traction mechanism can maintain continuous conveying, and the storage of the storage station will not exceed the storage capacity, thereby improving the processing speed of the potting machine; if the finished coil material in the storage station is insufficient, the cutting mechanism 26 can stop working and wait for the coil material. In order to make the potting machine run at high speed and stably, the finished coil material storage mechanism 25 also includes a detection component for detecting the storage amount of the finished coil material in the storage station, which is not drawn in the figure. The detection component, the feeding component and the cutting mechanism are all connected to the controller; when the detection component detects that the finished coil material in the storage station is insufficient, the controller sends a command to the feeding component 27 and the cutting mechanism 26, and the feeding component and the cutting mechanism stop working until the finished coil material in the storage station is sufficient, and the feeding component and the cutting mechanism resume working. The utility model coordinates cutting and finished product storage through the information collected by the detection component, so that there is a sufficient amount of finished coil material when the feeding component feeds the material, so that the coil material will not be loose due to too much finished coil material, nor will the coil material be stretched due to too little coil material and insufficient feeding, thereby eliminating the problem of unstable and inaccurate feeding, and making the filling machine run at high speed and stability. The detection component includes a first position sensor and a second position sensor for detecting the position of the tensioning roller. The two sensors are used to respectively collect the critical position of the tensioning roller on the guide rail. The feeding component pulls the finished coil material, and the finished coil material pulls the tensioning roller to move along the guide rail. If the first position sensor detects the slide or the tension roller, it means that the storage amount of the finished coil material at the storage station is less than the critical value, and the feeding and cutting operations need to be stopped. When the finished coil material at the waiting storage station increases, the tension spring causes the tension roller to move in the opposite direction along the guide rail, and the instruction to stop the operation is eliminated, and the feeding and cutting operations are resumed; if the amount of finished coil material at the waiting storage station is large, when the second position sensor detects the slide or the tension roller, it means that the storage amount of the finished coil material at the storage station is more than the critical value, then the feeding speed and the cutting frequency are increased, and the consumption of the finished coil material at the storage station is accelerated. In order to further improve the cutting accuracy, the finished coil material storage mechanism also includes a third position sensor for detecting the position of the finished coil material, and the third position sensor is connected to the controller; in the cutting condition, the feeding component pulls the finished coil material and collects the information of the finished coil material according to the third position sensor, and the controller sends an instruction to the cutting mechanism.The third position sensor detects a specific position of the finished coil, such as a protruding forming part after the coil is formed. The specific position can be set to one end or one side edge of the forming part. It is best to set the third position sensor close to the feeding component. After the feeding component delivers the fixed-length finished coil and the third position sensor detects the specific position, the controller sends a cutting instruction to the cutting mechanism to perform the cutting operation. If the third position sensor does not detect the specific position, it means that the position of the finished coil at the cutting station is not accurate. The controller sends an instruction to the cutting mechanism not to cut, thereby ensuring the accuracy of the cutting position.
