Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, specifically to a bagged straw cutting and conveying mechanism. Background Technology

[0002] In the packaging process of pharmaceutical packaging equipment, after oral liquid medicine bottles are placed in trays, individual bagged straws need to be placed inside. However, commercially available straw rolls are in a continuous winding form, with only easy-tear marks between each individual bag. Traditionally, manual tearing along the tear marks and placing them into the tray is required, which has problems such as low efficiency, high labor intensity, and poor consistency. In addition, the existing straw slitting and dispensing machine (CN206748500U) does not sort the straws in the individual packaging bags before slitting, which affects the slitting accuracy and the consistency of the straws. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an automated mechanism for cutting and conveying bagged straws, thereby solving the problem of inefficiency in manual operation. Furthermore, by sorting the straws within the individual packaging bags before cutting, the arrangement and position of the straws within the individual packaging bags are kept consistent, improving the consistency of the straws' condition and the cutting accuracy.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bagged straw slitting and conveying mechanism, comprising a frame, a rotatable unwinding drum on one side of the frame for mounting straw rolls; a sorting tray is provided on the frame near the unwinding drum, the sorting tray is provided with an elastic combing rod and a pressure roller, the lower end of the combing rod is provided with a material-pulling section with an inclination angle of less than 30°; a first feeding belt, a second feeding belt, an output belt and an output tray are arranged around the frame, the first feeding belt is located above the second feeding belt and the interval between the two is adjustable, the output belt is located above the output tray and the interval between the two is adjustable, and the interval between the first feeding belt and the second feeding belt is... The gap between the discharge belt and the discharge tray forms a downward-sloping straight channel. A slitting gap is provided between the first feed belt and the discharge belt, and a retractable slitting blade is provided in the slitting gap. The slitting blade is driven by a cylinder. The outlet of the discharge tray faces the upper part of the conveyor belt, and a grid is provided on the conveyor belt. A pressure sensor is provided between the first feed belt and the second feed belt. The pressure sensor is connected to the control processor. The cylinder is connected to the air pump through a solenoid valve. The control processor controls the opening and closing of the solenoid valve and drives the slitting blade through the cylinder to cut the tear lines of the suction tube roll. In this way, the control processor, through the solenoid valve and the cylinder, realizes that the slitting blade accurately cuts according to the tear lines.

[0005] The first feeding belt and the discharge belt are respectively adjusted in height by their respective lifting components. The lifting components include lifting seats that are guided and movable on the frame. The first feeding belt and the discharge belt are respectively installed on their respective lifting seats. A horizontal plate is mounted above the frame, and a rotatable screw is installed on the horizontal plate. A handwheel is configured at the upper end of the screw, and the lower end of the screw is threadedly connected to the lifting seat. The second feeding belt is installed on a pulley set on a fixed base. The first feeding belt and the discharge belt are respectively installed on their respective pulley sets and driven by a motor. A guide post is welded below the discharge tray, and a spring is provided on the guide post.

[0008] The downward tilt angle at both ends of the discharge tray is designed to facilitate the sliding of the straw packaging bag into the inlet between the first feed belt and the discharge tray.

[0009] The compartments on the conveyor belt are used to receive the individually packaged straws after they have been cut.

[0010] The beneficial effects of this utility model are: automation replaces manual labor, resulting in high cutting accuracy and efficiency; the cutting timing is controlled by pressure sensor feedback, and the adjustable spacing channel adapts to different specifications of straw rolls, making it highly versatile; the spring-buffered discharge tray ensures a smooth transition to the conveyor compartment, avoiding damage; at the same time, the straws are combed by the combing rod, ensuring that the straws in the individual packaging bags are placed in the same order and position before cutting, thus improving the consistency of the straws' condition and the cutting accuracy.

[0017] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] like Figure 1 — Figure 4 As shown, this embodiment discloses a bagged straw cutting and conveying mechanism, including a frame 1. A rotatable unwinding drum 3 is provided on one side of the frame 1 for mounting straw rolls. A sorting tray 4 is provided near the unwinding drum 3 on the frame 1. The sorting tray 4 is provided with an elastic combing rod 41 and a pressure roller 42. The lower end of the combing rod 41 is provided with a material-pushing section 411 with an inclination angle of less than 30°. A first feeding belt 5, a second feeding belt 6, an output belt 7, and an output tray 8 are arranged around the frame 1. The first feeding belt 5 is located above the second feeding belt 6, and the interval between them is adjustable. The output belt 7 is located above the output tray 8, and the interval between them is adjustable. The first feeding belt 5 and the second feeding belt... The intervals between the first feed belt 5 and the second feed belt 6, as well as the intervals between the discharge belt 7 and the discharge tray 8, form a downsloping straight channel. A slitting gap 9 is provided between the first feed belt 5 and the discharge belt 7, and a retractable slitting blade 11 is provided in the slitting gap 9. The slitting blade 11 is driven by a cylinder 10. The outlet of the discharge tray 8 faces the upper position of the conveyor belt 16, and a grid 161 is provided on the conveyor belt 16. A pressure sensor 17 is provided between the first feed belt 5 and the second feed belt 6. The pressure sensor 17 is connected to a control processor. The cylinder 10 is connected to an air pump through a solenoid valve. The control processor controls the opening and closing of the solenoid valve and drives the slitting blade 11 through the cylinder 10 to cut the tear marks on the suction tube roll.

[0019] The first feed belt 5 and the discharge belt 7 are respectively adjusted in height by their respective lifting components 12. The lifting component 12 includes a lifting seat 121 that is guided and movable on the frame 1. A pulley set is provided on the lifting seat 121. The first feed belt 5 and the discharge belt 7 are respectively mounted on their respective lifting seats 12. A horizontal plate 2 is mounted above the frame 1. A rotatable screw 122 is mounted on the horizontal plate 2. A handwheel 123 is provided at the upper end of the screw 122. The lower end of the screw 122 is threadedly connected to the lifting seat 121. The second feed belt 6 is mounted on a pulley set on a fixed base. The pulley set includes a large belt. The first feed belt 5 and the discharge belt 7 are respectively mounted on their respective pulley sets and driven by a motor, which is a servo motor. One of the pulleys on the pulley set is connected to the output shaft of the servo motor. A guide post 13 is welded below the discharge tray 8. A spring 14 is provided on the guide post 13. A guide seat 15 is installed on the frame 1. The guide seat 15 is provided with a guide hole for the guide post 13 to conduct. A nut is provided after the end of the guide post 13 passes through the guide hole. A spring step is provided on the inner wall of the guide hole. The spring 14 is located between the spring step and the lower end face of the discharge tray 8. The two ends of the discharge tray 8 are respectively inclined downward.

[0020] The combing rod 41 is made of elastic material and is used to help comb the straws in the individual packaging bags in the straw roll, so that the straws in the individual packaging bags are placed in the same order and position before cutting, which makes it easier for the pressure sensor 17 to monitor the accurate position of the straws in real time and improve the cutting accuracy.

[0021] The lifting assembly 12 adjusts the screw 122 by rotating the handwheel 123, thereby driving the lifting seat 121 to rise and fall, thereby adjusting the interval between the first feeding belt 5 and the second feeding belt 6, as well as the interval between the discharge belt 7 and the discharge tray 8.

[0022] The downward tilt angle at both ends of the discharge tray 8 is designed to facilitate the sliding of the straw packaging bag into the inlet between the first feed belt 5 and the discharge tray 8.

[0023] The compartments 161 on the conveyor belt 16 are used to receive the individually packaged straws after they have been cut.

[0024] The straw roll is fitted onto the unwinding drum 3 and initially straightened by the sorting tray 4 (guided by the inclined guide section 411 of the combing rod 411 and compacted by the pressure roller 42). It then enters the clamping channel between the first feeding belt 5 and the second feeding belt 6 (the spacing is adjusted by rotating the handwheel 123 and raising the screw 122 to lift the lifting seat 121), and is guided down the slope to the slitting gap 9. The pressure sensor 17 monitors the straw position in real time. When a tear is detected in the corresponding area, the control processor triggers the solenoid valve to drive the cylinder 10 to extend the slitting blade 11, cutting the individual packaging bag along the tear. The slitting single-pack straws are smoothly output to the grid 161 of the conveyor belt 16 via the discharge belt 7 and the discharge tray 8 (with spring 14 for shock absorption), completing the automatic slitting and conveying. The remaining individual packaging bag straws slide down the inclined downhill straight channel to the discharge belt 7 and the discharge tray 8.

[0025] The above solution achieves the following technical effects: automation replaces manual labor, resulting in high cutting accuracy and efficiency; the cutting timing is controlled by pressure sensor feedback, and the adjustable spacing channel adapts to different specifications of straw rolls, making it highly versatile; the spring-buffered discharge tray ensures a smooth transition to the conveyor compartment, preventing damage; at the same time, the straws are combed by the combing rod, ensuring that the straws in the individual packaging bags are placed in the same order and position before cutting, thus improving the consistency of straw condition and cutting accuracy.
