Description

Technical Field

[0001] This application relates to the field of paper processing technology, and in particular to a paper card mounting device. Background Technology

[0002] Laminating equipment belongs to the field of paper processing technology, specifically a device used to fold paper cards in half and glue the two sides together. While existing paper card laminating equipment has improved production efficiency to some extent, several problems remain in actual operation. For example, when feeding paper cards, the conveyor belt carrying the paper to be loaded needs to be aligned and close to the feeding mechanism's conveyor belt, or the paper needs to be placed manually on the conveyor belt, resulting in low operational efficiency. Furthermore, individual sheets of paper are easily affected by external factors or their own movement during transport, leading to edge curling or unevenness, uneven glue application, or even failure to enter the rollers of the next process, resulting in a high scrap rate. To improve the processing efficiency and production quality of the laminating machine, the structure of the device needs further improvement to solve the aforementioned problems. Summary of the Invention

[0003] In order to achieve better and more even glue application on paper cards, reduce the scrap rate, and perform paper card mounting, this application provides a paper card mounting device.

[0004] This application provides a paper card mounting device, which adopts the following technical solution: A paper card mounting device includes a first conveyor belt, a feeding mechanism, and a first frame. The first conveyor belt is mounted on the first frame. The feeding mechanism includes a rotating rod rotatably connected to the first frame and located above the first conveyor belt. A support frame is fixed on the rotating rod, and a connecting rod is rotatably connected to the support frame. The rotating rod drives the connecting rod to revolve around its central axis. The connecting rod is located at the input end of the feeding mechanism, and several picking rods are connected to the connecting rod. When the connecting rod revolves, it drives the lower ends of the picking rods to move closer to or away from the first conveyor belt in the vertical direction. The lower ends of the picking rods are equipped with suction cups, and the upper ends of the picking rods are connected to a negative pressure device pipeline. The first frame also has a first drive assembly, which is driven by the connecting rods. The first drive assembly drives the connecting rods to rotate, and when the connecting rods rotate, they drive the lower ends of the picking rods to move closer to or away from the first conveyor belt in the horizontal direction.

[0005] By adopting the above technical solution, the rotating rod is rotatably connected to the first frame, and the rotating rod rotates around its own central axis. A support frame is fixed on the rotating rod, and a connecting rod is rotatably connected to the support frame. The connecting rod is arranged parallel to the rotating rod, and the rotating rod is driven by the support frame and the connecting rod, so that the connecting rod can revolve around the central axis of the rotating rod. Several picking rods are connected to the connecting rod. When the connecting rod revolves, it drives the lower end of the picking rod to move closer to or away from the first conveyor belt in the vertical direction. In addition, the first drive assembly drives the connecting rod to rotate around its own central axis. The rotation of the connecting rod drives the lower end of the picking rod to move closer to or away from the first conveyor belt in the horizontal direction. The rotation and revolution of the connecting rod cooperate with each other, causing the lower end of the picking rod to swing back and forth. Approaching or moving away from the input end of the first conveyor belt, when the picking rod swings away from the input end of the first conveyor belt, the suction cup at the lower end of the picking rod approaches the paper card to be picked up. The suction cup uses a negative pressure device to pick up the paper card. When the picking rod swings close to the input end of the first conveyor belt, the suction cup drives one end of the paper card close to the first conveyor belt and sends the paper card into the feeding mechanism to complete the picking up. This realizes single-sheet picking up of paper cards, which is convenient and fast, helps to reduce the labor intensity of workers and improve work efficiency. In addition, several picking rods are set along the extension direction of the rotating rod, and the linearly arranged suction cups grab one side edge of the paper card, so that the paper card enters the feeding mechanism relatively straight, ensuring the adsorption effect while also taking into account the balance of adsorption.

[0006] Optionally, the feeding mechanism further includes at least two bridges, both ends of which are fixed to the first frame. The bridges span across the top of the first conveyor belt, and several pressure plates are provided between the bridges and the first conveyor belt. The pressure plates extend along the conveying direction of the first conveyor belt, and the bridges and pressure plates are detachably connected.

[0007] By adopting the above technical solution, the cable tray and the pressure plate are detachably connected. The pressure plate is suspended above the first conveyor belt. The distance between the pressure plate and the first conveyor belt allows paper cards to enter. By adjusting the connecting parts of the cable tray and the pressure plate, the distance between the pressure plate and the first conveyor belt can be adjusted. After the paper card enters the feeding mechanism, at least one end of the pressure plate is close to the paper card, so that the paper card is limited between the pressure plate and the first conveyor belt, preventing the paper card from bending. No manual adjustment is required, which can prevent the paper from being bent, resulting in uneven gluing or even failing to enter the rollers of the next process, thus reducing the scrap rate.

[0008] Optionally, the pressure plate has a plurality of bead holes that penetrate the upper and lower sides of the pressure plate. A portion of the bead holes contain steel balls. The outer diameter of the steel balls is smaller than the inner diameter of the bead holes. The outer diameter of the steel balls is larger than the vertical distance between the bottom of the bridge frame and the top surface of the first conveyor belt. The lower side of the steel balls abuts against the top surface of the first conveyor belt.

[0009] By adopting the above technical solution, the steel ball is confined within the bead hole and can rotate within the bead hole due to friction. When the paper card enters the feeding mechanism, it is pressed between the steel ball and the first conveyor belt, increasing the friction between the paper card and the first conveyor belt and preventing the paper from curling at the edges as much as possible, so that the paper card can enter the roller of the next process more smoothly.

[0010] Optionally, the end of the pressure plate near the input end of the feeding mechanism is bent upward to form a bent portion. The bottom surface of the bent portion is an arc surface. The end of the pressure plate with the bent portion is provided with a roller support. The roller support is rotatably connected to a pre-compression roller. The pre-compression roller abuts against the top surface of the first conveyor belt.

[0011] By adopting the above technical solution, when the suction cup sends the paper card to the input end of the first conveyor belt, the paper card enters the feeding mechanism from the tangent point between the pre-pressing roller and the first conveyor belt, achieving the purpose of flat conveying and making the paper card smoothly transition to the feeding mechanism.

[0012] Optionally, a second frame is included, on which a glue extrusion roller mounting seat is provided. The glue extrusion roller mounting seat is close to the output end of the first conveyor belt. The glue extrusion roller mounting seat is slidably connected to the second frame. A glue extrusion roller is rotatably mounted on the glue extrusion roller mounting seat. The input end of the glue extrusion roller is connected to the output end of the first conveyor belt for transmission. A glue coating roller is rotatably connected to the second frame. The glue coating roller and the glue extrusion roller are close to each other and rotate towards each other.

[0013] By adopting the above technical solution, the extrusion roller mounting base is slidably connected to the second frame. By controlling the position of the extrusion roller mounting base, the distance between the extrusion roller and the coating roller is adjusted, thereby adjusting the amount of glue applied. The coating roller and the extrusion roller rotate in opposite directions. When the glue falls onto the coating roller or the extrusion roller, the rotation of the coating roller or the extrusion roller causes the glue to fall into the gap between the coating roller and the extrusion roller. The coating roller and the extrusion roller squeeze the glue, thereby defoaming the glue and preventing air bubbles from affecting the glue application quality. This would cause dents or raised wrinkles after the paper cards are laminated, affecting the quality of the paper card products. The mutual squeezing of the coating roller and the extrusion roller ensures that the glue is evenly applied to the coating roller, preventing uneven glue application, improving production quality, and reducing the scrap rate.

[0014] Optionally, a pressure slit is formed between the coating roller and the extrusion roller, and a glue outlet is also provided on the second frame, which is located above the pressure slit. A recycling bin is also provided below the coating roller and the extrusion roller for collecting dripping glue.

[0015] By adopting the above technical solution, excess glue can be collected, preventing glue drips from polluting the production environment, reducing the difficulty of subsequent cleaning, and the collected glue can be reused, reducing glue waste.

[0016] Optionally, it includes a third frame and a third conveyor belt. The third conveyor belt is mounted on the third frame. The input end of the third conveyor belt is connected to the output end of the coating roller. The third conveyor belt has several strips arranged at intervals. A flap is provided between two adjacent strips. The initial position of the flap forms a first angle with the third conveyor belt. The flap extends at least partially out of the upper surface of the third conveyor belt. A drive rod is rotatably connected to the third frame. One end of the flap is fixedly connected to the drive rod.

[0017] By adopting the above technical solution, after the paper card is coated with glue by the glue roller, it is conveyed to the third conveyor belt. The flip plate is set between the strips, and the strips and flip plates are alternately set to make the paper card evenly stressed and better adaptable to paper cards of different widths. The initial position of the flip plate forms a first angle with the third conveyor belt. The flip plate extends at least partially out of the upper surface of the third conveyor belt. The side projection of the flip plate and the third conveyor belt intersects, so that the paper card can be conveyed to the flip plate relatively smoothly. When the bending part of the paper card is transported to the intersection of the flip plate and the third conveyor belt, the drive rod drives the flip plate to flip towards the third conveyor belt to complete the mounting of the paper card.

[0018] Optionally, the drive rod is located above the third conveyor belt, and the extension direction of the drive rod is perpendicular to the conveying direction of the third conveyor belt. The third frame is also provided with a second drive assembly, which is connected to the drive rod in a transmission manner. The second drive assembly is used to drive the drive rod to reciprocate.

[0019] By adopting the above technical solution, the second drive component is connected to the drive rod for transmission. The second drive component drives the drive rod to rotate back and forth, and the drive rod drives the flip plate to flip at a certain frequency. When the flip plate flips to be parallel with the third conveyor belt, the paper card is completed and automatically transported with the third conveyor belt, realizing full automation. The structure is simple and easy to use.

[0020] Optionally, the second drive assembly includes a chain, a sprocket, a first drive member, and a second drive member. The sprocket is fixed to one end of a drive rod and rotates coaxially with the drive rod. The chain is wrapped around the sprocket and meshes with it. One end of the chain is fixed to the output end of the first drive member via one side of the sprocket, and the other end of the chain is fixed to the output end of the second drive member via the other side of the sprocket. The first drive member and the second drive member are alternately controlled in a cyclic manner.

[0021] By adopting the above technical solution, the first driving component and the second driving component alternately and cyclically control the two ends of the chain to push and pull alternately and cyclically, so that the sprocket rotates back and forth within a certain angle. The sprocket and the driving rod rotate coaxially, so that the driving rod also rotates back and forth within a certain angle, thereby realizing the flip plate flipping at a certain frequency and angle, and realizing automated paper card mounting.

[0022] Optionally, a second conveyor belt is included, which is located between the third conveyor belt and the coating roller. The input end of the second conveyor belt is connected to the output end of the coating roller, and the output end of the second conveyor belt is connected to the input end of the third conveyor belt.

[0023] By adopting the above technical solution, after the paper card is glued, it is conveyed by the second conveyor belt, which increases the transmission time of the paper card and allows the glue to pre-cur on the paper card. This improves the problem of air bubbles during the paper card mounting process, prevents the paper card from flowing downwards when one side is raised to a certain height, keeps the glue and its edges flat, and alleviates the overflow of glue under pressure.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Multiple suction cups arranged in a linear fashion use a negative pressure device to pick up the paper card from one side edge. When the picking rod swings to the input end near the first conveyor belt, the suction cups grab the paper card and bring one end of the paper card close to the first conveyor belt, thus feeding the paper card into the feeding mechanism to complete the picking. This is convenient and fast, and the paper card enters the feeding mechanism relatively straight. Multiple suction cups ensure the adsorption effect while also taking into account the balance of adsorption. 2. The rotation and revolution of the connecting rod work together to make the lower end of the reciprocating swing of the picking rod approach or move away from the input end of the first conveyor belt, so as to pick up paper cards on different height platforms and automatically feed the paper cards into the feeding mechanism. It is highly flexible, convenient for automatic feeding, and reduces manpower consumption. 3. The pre-pressing rollers, pressure plates, and steel balls work together to limit the paper card, preventing the edges of the paper card from curling up during transmission as much as possible. The steel balls press against the top surface of the paper card, increasing the friction between the paper card and the first conveyor belt, and making the paper card enter the rollers of the next process more smoothly.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] This application discloses a paper card mounting device.

[0033] Reference Figure 1 and Figure 2 A paper card mounting device includes a first conveyor belt 12, a feeding mechanism, and a first frame 11. The first conveyor belt 12 is mounted on the first frame 11. The feeding mechanism includes a rotating rod 21, which is rotatably connected to the first frame 11. The rotating rod 21 reciprocates within a certain angle around its central axis. The rotating rod 21 is located above the first conveyor belt 12 and close to the input end of the feeding mechanism. The extension direction of the rotating rod 21 is perpendicular to the conveying direction of the first conveyor belt 12. A support frame 22 is fixed on the rotating rod 21. One end of the support frame 22 is fixed to the rotating rod 21, and the other end of the support frame 22 is rotatably connected to a connecting rod 23. The rotating rod 21 is connected to the connecting rod 23 via the support frame 22, allowing the connecting rod 23 to revolve around the central axis of the rotating rod 21. The connecting rod 23 is arranged parallel to the rotating rod 21 and is located at the input end of the feeding mechanism. Several picking rods 24 are connected to the connecting rod 23. The outer side walls of the upper ends of the connecting rod 23 and the picking rods 24 are fixed to each other. The extension direction of the connecting rod 23 is perpendicular to the extension direction of the picking rods 24. When the connecting rod 23 revolves, it drives the lower end of the picking rods 24 to move closer to or further away from the first conveyor belt 12 in the vertical direction, thereby realizing the picking of paper cards placed at different heights. This method is highly flexible, facilitates automatic feeding, and reduces manpower consumption.

[0034] In this embodiment, four picking rods 24 are provided. The lower end of the picking rod 24 is provided with a suction cup 25, and the upper end of the picking rod 24 is connected to the pipeline of the negative pressure equipment. The paper is picked up by vacuum adsorption of one side of the paper card using the negative pressure equipment. By swinging the picking rod 24, one side of the paper card is sent to the input end of the feeding mechanism. The negative pressure equipment stops vacuuming, allowing the paper card to enter the feeding mechanism to complete the picking. This is convenient and quick, which helps to reduce the labor intensity of workers and improve work efficiency. In addition, the picking rods 24 are arranged along the extension direction of the rotating rod 21, and the linearly arranged suction cups 25 grab the edge of one side of the paper card, so that the paper card enters the feeding mechanism relatively straight, ensuring the adsorption effect while also taking into account the balance of adsorption.

[0035] The first frame 11 is also equipped with a first drive assembly 26, which drives the connecting rod 23 to rotate. The first drive assembly 26 includes a transmission arm 261, one end of which is fixedly connected to the connecting rod 23, and the other end of which has a rectangular sliding groove 262 with a rounded end. The inner wall of the first frame 11 is equipped with a drive cylinder 264, and the output end of the drive cylinder 264 is fixed with a transmission rod 263. One end of the transmission rod 263 is fixed to the drive cylinder 264, and the other end of the transmission rod 263 passes through the sliding groove 262. The transmission rod 263 is confined in the sliding groove 262, which allows for vertical movement of the connecting rod 23 during its revolution. The drive cylinder 264 drives the transmission rod 263 to translate horizontally. The connecting rod 23 reciprocates around its central axis within a certain angle. This rotation causes the lower end of the picking rod 24 to move horizontally towards or away from the first conveyor belt 12. The rotation and revolution of the connecting rod 23 work together to make the lower end of the picking rod 24 swing towards or away from the input end of the first conveyor belt 12. When the picking rod 24 swings away from the input end of the first conveyor belt 12, the suction cup 25 at the lower end of the picking rod 24 approaches the paper card to be picked up. The suction cup 25 uses a negative pressure device to pick up the paper card. When the picking rod 24 swings towards the input end of the first conveyor belt 12, the suction cup 25 drives one end of the paper card towards the first conveyor belt 12 and sends the paper card into the feeding mechanism to complete the automated picking up and effectively improve work efficiency.

[0036] Reference Figure 1 and Figure 3The feeding mechanism also includes at least two cable trays 31. In this embodiment, there are two cable trays 31. Both ends of the cable trays 31 are fixed to the first frame 11. The cable trays 31 span across the top of the first conveyor belt 12 and are arranged perpendicular to the conveying direction of the first conveyor belt 12. Several pressure plates 41 are provided between the cable trays 31 and the first conveyor belt 12. In this embodiment, there are four pressure plates 41. The pressure plates 41 are suspended above the first conveyor belt 12. The gap between the pressure plates 41 and the first conveyor belt 12 allows paper cards to enter. The pressure plates 41 extend along the conveying direction of the first conveyor belt 12. The cable trays 31 and the pressure plates 41 are detachably connected. Each cable tray 31 has four screws evenly spaced. Hole 32 and screw hole 32 are connected vertically. Pressure plate 41 is provided with through hole 47 corresponding to screw hole 32. Bolt passes through screw hole 32 and its corresponding through hole 47 to connect pressure plate 41 to the bottom of two bridge frames 31. By adjusting bolt 33, the distance between pressure plate 41 and first conveyor belt 12 can be adjusted. Pressure plate 41 gradually moves away from first conveyor belt 12 along the direction from input end to output end. After the paper card enters the feeding mechanism, at least one end of pressure plate 41 is close to the paper card, so that the paper card is limited between pressure plate 41 and first conveyor belt 12 to prevent the paper card from bending. No manual adjustment is required. This can prevent the paper from being glued unevenly due to bending or even failing to enter the roller of the next process, thus reducing the scrap rate.

[0037] Reference Figure 1 and Figure 3 The pressure plate 41 has a plurality of bead holes 42. In this embodiment, each pressure plate 41 has six bead holes 42. The bead holes 42 are evenly distributed along the extension direction of the pressure plate 41. The bead holes 42 penetrate the upper and lower sides of the pressure plate 41. A steel ball 43 is provided in the bead hole 42. The steel ball 43 is confined within the bead hole 42. The outer diameter of the steel ball 43 is smaller than the inner diameter of the bead hole 42. The outer diameter of the steel ball 43 is larger than the vertical distance between the bottom of the bridge frame 31 and the top surface of the first conveyor belt 12. The steel ball 43 can rotate in the bead hole 42 due to friction. The lower side of the steel ball 43 abuts against the top surface of the first conveyor belt 12. When the paper card enters the feeding mechanism, it is pressed between the steel ball 43 and the first conveyor belt 12, increasing the friction between the paper card and the first conveyor belt 12 and preventing the paper from curling as much as possible, so that the paper card can enter the roller of the next process more smoothly.

[0038] Reference Figure 1 and Figure 3The end of the pressure plate 41 near the input end of the feeding mechanism is bent upward to form a bent part 44. The bottom surface of the bent part 44 is arc-shaped to prevent the pressure plate 41 from scratching the paper card and forming indentations, which would affect the quality of the paper card. The end of the pressure plate 41 with the bent part 44 is provided with a roller support 45. The roller support 45 extends out of the outside of the pressure plate 41. The roller support 45 is rotatably connected to a pre-pressing roller 46. The pre-pressing roller 46 abuts against the top surface of the first conveyor belt 12. When the suction cup 25 sends the paper card to the input end of the first conveyor belt 12, the paper card enters the feeding mechanism from the tangent point between the pre-pressing roller 46 and the first conveyor belt 12, achieving the purpose of flat conveying and making the paper card smoothly transition to the feeding mechanism.

[0039] Reference Figure 1 The card mounting equipment also includes a second frame 51, on which a glue extrusion roller mounting seat 52 is provided. The glue extrusion roller mounting seat 52 is close to the output end of the first conveyor belt 12. The glue extrusion roller mounting seat 52 is slidably connected to the second frame 51. The glue extrusion roller mounting seat 52 and the second frame 51 are fixed together by an adjusting screw 56. The adjusting screw 56 is vertically set. By rotating the adjusting screw 56, the vertical position of the glue extrusion roller mounting seat 52 can be adjusted. A glue extrusion roller 53 is rotatably mounted on the glue extrusion roller mounting seat 52. The input end of the glue extrusion roller 53 is connected to the output end of the first conveyor belt 12 for transmission. A glue coating roller 54 is rotatably connected to the second frame 51. The glue coating roller 54 and the glue extrusion roller 53 are close to each other, and a pressure is formed between the glue coating roller 54 and the glue extrusion roller 53. The gap 55 is created by controlling the glue extrusion roller mounting base 52 to move closer to or further away from the glue coating roller 54, thereby adjusting the amount of glue applied. The glue coating roller 54 and the glue extrusion roller 53 rotate in opposite directions. When glue falls onto the glue coating roller 54 or the glue extrusion roller 53, the rotation of the glue coating roller 54 or the glue extrusion roller 53 causes the glue to fall into the gap 55. The glue coating roller 54 and the glue extrusion roller 53 squeeze the glue, thereby defoaming the glue and preventing air bubbles from affecting the glue application quality. This would cause dents or raised wrinkles after the paper cards are laminated, affecting the quality of the paper card products. The mutual squeezing of the glue coating roller 54 and the glue extrusion roller 53 ensures that the glue is evenly applied to the glue coating roller 54, preventing uneven glue application, improving production quality, and reducing the scrap rate.

[0040] The second frame 51 is also equipped with a glue outlet, which is located above the pressure seam 55. A recycling bin is also provided below the glue application roller 54 and the glue extrusion roller 53. The recycling bin collects excess glue to prevent glue from dripping and polluting the production environment as much as possible, reducing the difficulty of subsequent cleaning. The collected glue can be reused to reduce glue waste.

[0041] Reference Figure 1 and Figure 4The paper card mounting equipment also includes a second conveyor belt 60. The input end of the second conveyor belt 60 is connected to the output end of the glue roller 54. After the paper card is glued, it is conveyed by the second conveyor belt 60, which increases the transmission time of the paper card. The glue is pre-cured on the paper card, which improves the problem of air bubbles during the paper card mounting process and prevents the paper card from flowing downward when one side is raised to a certain height. This keeps the glue and its edges flat and alleviates the overflow of glue under pressure.

[0042] Reference Figure 4 and Figure 5 The paper card mounting equipment also includes a third frame 71 and a third conveyor belt 72. The third conveyor belt 72 is mounted on the third frame 71. The input end of the third conveyor belt 72 is connected to the output end of the second conveyor belt 60. After the paper cards are glued by the glue roller 54, they are conveyed onto the third conveyor belt 72. The third conveyor belt 72 has several spaced strips, and a flip plate 73 is provided between two adjacent strips. The strips and flip plates 73 are alternately arranged to ensure that the paper cards are evenly stressed and to better adapt to paper cards of different widths. The initial position of the flip plate 73 is connected to the third frame 71. When the conveyor belt 72 forms a first angle, an obtuse angle is formed between the A surface of the flip plate 73 and the top surface of the third conveyor belt 72. The flip plate 73 extends at least partially beyond the upper surface of the third conveyor belt 72. The side projection of the flip plate 73 intersects with that of the third conveyor belt 72, allowing the paper card to be conveyed to the flip plate 73 relatively smoothly. A drive rod 74 is rotatably connected to the third frame 71. When the side of the paper card to be folded is conveyed to the flip plate 73, the folded part of the paper card abuts against the intersection. The drive rod 74 drives the flip plate 73 to flip towards the third conveyor belt 72, completing the mounting of the paper card.

[0043] Reference Figure 4 and Figure 5 The drive rod 74 is located above the third conveyor belt 72, and the extension direction of the drive rod 74 is perpendicular to the conveying direction of the third conveyor belt 72. A mounting frame 76 is fixedly installed on the third frame 71, and a stop bar 77 is slidably connected to the mounting frame 76. The stop bar 77 is parallel to the drive rod 74 and is located above the third conveyor belt 72. In the initial state, the B side of the flip plate 73 abuts against the stop bar 77. By adjusting the height of the stop bar 77 on the mounting frame 76, the initial angle of the flip plate 73 can be limited and support can be provided for the flip plate 73. The third frame 71 is also provided with a second drive assembly 75, which is connected to the drive rod 74. The second drive assembly 75 drives the drive rod 74 to rotate back and forth, thereby driving the flip plate 73 to flip at a certain frequency. When the flip plate 73 flips to be parallel to the third conveyor belt 72 and the A side of the flip plate 73 is opposite to the top surface of the third conveyor belt 72, the paper card is completed and automatically conveyed with the third conveyor belt 72, realizing full automation. The structure is simple and easy to use.

[0044] Reference Figure 4 and Figure 5The second drive assembly 75 includes a chain 752, a sprocket 751, a first drive member 753, and a second drive member 754. The sprocket 751 is fixed to one end of the drive rod 74 and rotates coaxially with the drive rod 74. The chain 752 wraps around the sprocket 751 and meshes with it. The first drive member 753 and the second drive member 754 are fixed to the third frame 71. One end of the chain 752 is fixed to the output end of the first drive member 753 via the upper side of the sprocket 751.
