[0022] The bag feeding mechanism of the stringing machine comprises a transmission belt 37 and bag clamping components 38 arranged on the transmission belt. The transmission belt is arranged longitudinally on the frame. In order to improve the stability of clamping, one bag body is clamped by two bag clamping components, i.e. one bag body is clamped by a group of bag clamping components. The bag clamping components 38 are arranged in groups, and each group of bag clamping components is uniformly distributed on the transmission belt 37. The transmission belt sends the bag clamping components 38 to various work stations, such as punching work stations and stringing work stations. The bag clamping components 38 comprise a mounting seat 49, left and right moving plates moving leftward and rightward on the mounting seat, and a driving member for clamping the left and right moving plates. The mounting seat 49 is transversely arranged on the transmission belt 37. The left and right moving plates each comprise a bottom plate and a clamping plate. The clamping plate is arranged vertically. The clamping plates of the left and right moving plates are respectively left and right clamping plates 46 and 45. The bottom plates of the left and right moving plates are respectively left and right bottom plates 48 and 50. The left clamping plate 46 is arranged at the right end of the left bottom plate 48. The right clamping plate 45 is arranged at the left end of the right bottom plate 50. The driving member moves the left and right moving plates toward each other and makes the left and right clamping plates 46 and 45 press and close to clamp the bag body 2. If there is no external force, the driving member keeps the left and right clamping plates 46 and 45 in the clamping state. If the external force overcomes the force of the driving member on the left and right moving plates and makes the left and right clamping plates separate, the bag clamping component is opened, and the bag body 2 can be put in or taken out at this time. Left and right guide blocks 52 are arranged on the mounting seat 49. Left and right sliding grooves 54 are arranged on the left and right bottom plates 48 and 50 respectively and slide with the left and right guide blocks 52. When the left and right moving plates move toward each other or in the opposite direction on the mounting seat, the left and right guide blocks 52 move in the left and right sliding grooves 54 respectively, so that the left and right moving plates move stably along a straight line. In this way, the bag clamping component is switched between opening and clamping stably.

[0023] The driving member for driving the left and right moving plates to clamp can be driven by a spring or an air cylinder. Two embodiments are described below.

[0024] Embodiment one is shown in the accompanying drawings. Figures 3-5The driving member is a spring 44, the left guide block passes through the left sliding slot and is connected with the left limiting block 43 above the left bottom plate 48, the right guide block 52 passes through the right sliding slot 54 and is connected with the right limiting block 47 above the right bottom plate, the left clamping plate 46 is arranged on the right side of the right clamping plate 45, the spring 44 is arranged between the left limiting block 43 and the right clamping plate 45 and between the right limiting block 47 and the left clamping plate 46, the left limiting block and the right limiting block are mounted on the mounting seat 49 and are fixed, the force of the spring 44 makes the left clamping plate 46 and the right clamping plate 45 adhere and clamp, when external force drives the left bottom plate 48 and the right bottom plate 50 to move towards each other, the left clamping plate and the right clamping plate are separated, after the external force is removed, the elastic force of the spring makes the left clamping plate 46 and the right clamping plate 45 adhere again. In order to make the bag clamping part compact, the left clamping plate and the right clamping plate have sufficient clamping area and firm clamping, the right end of the left bottom plate 48 is provided with a reverse L-shaped notch one, the left end of the right bottom plate 49 is provided with an L-shaped notch two 53, the notch one and the notch two are arranged in a staggered manner, that is, the notch one is on the front side and the notch two is on the rear side, the left clamping plate 46 passes around the right clamping plate 45 and is arranged on the right side of the right clamping plate, so that the right end of the left bottom plate and the left end of the right bottom plate are spliced, the right end of the left bottom plate moves left and right in the notch two 53, and the left end of the right bottom plate moves left and right in the notch one; if the notch one and the notch two occupy half of the width of the left bottom plate and the right bottom plate respectively, the width of the right end of the left bottom plate and the left end of the right bottom plate after splicing is consistent with the width of the left end of the left bottom plate and the right end of the right bottom plate, so that the overall structure is more compact and exquisite.

[0025] The lower ends of the left guide block and the right guide block 52 are provided with limiting grooves, the mounting seat 49 is provided with a left limiting protrusion 51 and a right limiting protrusion 55 matched with the two limiting grooves respectively, so that the bag clamping part is convenient to disassemble and achieves the limiting effect.

The power assembly two can adopt the structure of power assembly one, or can adopt mechanical structure, the power assembly two includes left limiting plate 41 and right limiting plate 40, the left limiting plate and right limiting plate are respectively installed longitudinally on left wall plate 56 and right wall plate 57 of rack, the interval between left limiting plate and right limiting plate is less than the distance from left bottom plate to right bottom plate when left clamp plate and right clamp plate close. The left and right wall plates form bag feeding channel 58, the setting of left and right limiting plates makes the bag feeding channel of discharge work station smaller, the width of bag feeding channel of other work stations is not less than the maximum width from left bottom plate to right bottom plate, when left clamp plate and right clamp plate close, the width from left bottom plate to right bottom plate is maximum, the width of mounting seat is less than the maximum width, also less than the interval of left and right limiting plates, the width of bag feeding channel of other work stations is not less than the maximum width, so that it does not affect the clamping operation of bag clamping component, when in discharge work station, the bag feeding channel becomes narrow, the interval between left limiting plate and right limiting plate is less than the maximum width, so that left limiting plate and right limiting plate force left bottom plate and right bottom plate to move towards each other on mounting seat, so that left and right clamp plates open automatically. In order to make bag clamping component enter discharge work station stably, the bag feeding channel 58 of the inlet end of left limiting plate and right limiting plate gradually becomes smaller, the inlet end of left limiting plate 41 and right limiting plate 40 is inclined surface or arc surface, the left end of left bottom plate and the right end of right bottom plate are provided with rotatable wheels or bearings 42, the wheels or bearings are slidingly matched with left limiting plate and right limiting plate, so that bag clamping component enters discharge work station smoothly. When left clamp plate and right clamp plate open, bag body enters between them, the bottom of bag body contacts with mounting seat, the dust and oil stains on mounting seat will adhere to the bottom of bag body, affecting the quality of bag body, the lower end of right clamp plate is provided with transversely arranged supporting rod 76, the left clamp plate is provided with through hole 77 for supporting rod to pass through, when left and right clamp plates open, bag body enters between the two clamp plates, supporting rod supports bag body, and then left and right clamp plates clamp bag body, so as to avoid the contact between bag body and mounting seat, so that the bottom of bag body also remains clean.

[0026] In the second embodiment, the driving member is a cylinder which is mounted on the mounting base. The left moving plate and the right moving plate are respectively connected with a cylinder. The left clamping plate is arranged on the left side of the right clamping plate. The cylinder drives the left moving plate and the right moving plate to move towards or reversely, so as to realize the clamping or opening of the left clamping plate and the right clamping plate. The arrangement of the guide groove and the guide block ensures the stable movement of the left moving plate and the right moving plate.

[0027] The transmission belt 37 can adopt a transmission chain which facilitates the installation of the bag clamping member. The discharge end of the transmission belt is further provided with an upper conveying member 36. After the bag body 2 is threaded, it enters the discharge station. The bag clamping member 38 is opened at the discharge station, and then is sent out by the upper conveying member 36. The upper conveying member includes a left transmission assembly and a right transmission assembly which are pressed together. The transmission speed of the upper conveying member 36 is consistent with that of the transmission belt 37. The left transmission assembly includes a transmission belt two 58 which is arranged vertically. The right transmission assembly can also adopt a vertically arranged transmission belt. The two transmission belts are pressed together to convey the bag body. In this embodiment, the right transmission assembly includes a pressure roller group which includes pressure rollers 59. The pressure roller group is arranged in several groups. When the pressure rollers 59 are pressed together with the transmission belt two 58, the bag body 2 is conveyed. In order to improve the pressing effect, the transmission belt two 58 is provided with pressure rollers two 61. The pressure roller group further includes a longitudinally arranged mounting plate 64. The pressure rollers 59 are mounted on one end of a swing arm 60. The swing arm is hinged to the mounting plate 64. The swing arm has two stations on the mounting plate, i.e. a pressing station and a stopping station. When the swing arm 60 is at the pressing station, the pressure rollers 59 are pressed together with the transmission belt two 58. When the swing arm 60 is at the stopping station, the pressure rollers 59 are lowered to be separated from the transmission belt two 58. The swing of the swing arm 60 can be driven by a power source such as a cylinder. See the attached drawings. Figure 5The installation plate 64 is provided with a spring 67 arranged transversely, one end of the spring 67 acts on the swing arm 60, and the other end of the spring 67 acts on the limiting plate 62. In order to facilitate the installation of the spring and ensure the stability of the spring force, the installation plate is provided with a transverse channel 75. The swing arm is provided with a spring installation slot 65, that is, the spring 67 is arranged in the transverse channel, and the end of the swing arm on which the spring acts is arranged in the installation slot 65. The limiting plate 62 is installed on the installation plate 64, the top rod 63 is hinged to the installation plate 64, the front limiting block 70 and the rear limiting block 71 are respectively arranged on the front side and the rear side of the top rod, the spring force pushes the swing arm 60 to swing upward, so that the pressing wheel 59 is pressed toward the transmission belt two, and the top rod 63 and the swing arm 60 adopt the lever principle, so that the pressing wheel is pressed to the transmission belt or separated from the transmission belt. The hinged part 66 of the top rod and the installation plate is arranged on the right side of the front limiting block and the rear limiting block, the force of the spring 67 acting on the swing arm makes the right end of the swing arm swing backward, in the pressing state, the leg part 69 of the swing arm is clamped in the neck part 73 of the top rod, and the rear limiting block 71 blocks the rear side of the top rod 63. The upward spring force of the spring acts on the swing arm, the swing arm swings clockwise, the leg part 69 of the swing arm is pressed toward the neck part 73 of the top rod, the top rod 63 swings counterclockwise, the rear limiting block blocks the top rod, and the swing arm and the top rod are kept in the pressing state, at this time, the pressing wheel 59 is pressed toward the transmission belt two. In the shutdown state, the top rod 63 is swung by external force, the top part 68 of the top rod swings backward, that is, the top rod swings clockwise, the top part 68 of the top rod pushes the swing arm to swing forward, that is, the top rod overcomes the spring force to make the swing arm swing counterclockwise, the pressing wheel 59 is separated from the transmission belt two, and has a gap, the top part 68 of the top rod abuts against the leg part 69 of the swing arm, at this time, the front limiting block 70 blocks the front side of the top rod, so that the swing arm and the top rod are kept in the shutdown state. The positions of the hinged part 66 of the swing arm and the installation plate, the hinged part of the top rod and the installation plate, the left and right limiting blocks and the position of the spring acting on the swing arm will affect the swinging directions of the swing arm and the top rod, so the positional relationship of them needs to be coordinated with each other. If the hinged part of the top rod and the installation plate is arranged on the left side of the front limiting block and the rear limiting block, the force of the spring acting on the swing arm makes the right end of the swing arm swing backward, in the pressing state, the leg part of the swing arm is clamped in the neck part of the top rod, the front limiting block blocks the front side of the top rod, and limits the top rod from continuing to swing. In the shutdown state, the top rod swings backward, the top part of the top rod pushes the swing arm to swing forward, the top part of the top rod abuts against the leg part of the swing arm, and the rear limiting block blocks the rear side of the top rod. The positions of the hinged part 66 of the swing arm and the installation plate, the hinged part of the top rod and the installation plate, the left and right limiting blocks and the position of the spring acting on the swing arm are not limited to the above two cases.

[0028] The bag body is sent from the unloading station to different stations by the bag clamping component. After the bag body is completed with the string, the bag clamping component sends the bag body to the discharging station, and the upper conveying component takes over. In the process of transferring, the upper end of the bag body enters the upper conveying component, and the lower end is still conveyed by the bag clamping component. The bag body can be conveyed stably only when the upper conveying component and the bag clamping component are synchronous. If there is a difference in the transmission of the upper conveying component and the bag clamping, the compression wheel will produce friction marks on the surface. In order to reduce the pressure marks, the use of the compression wheel group can be reduced, that is, the swing rod is swung to the stop station.
