Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper packaging machine technology, and in particular to a bottle-rolling mechanism with overload protection. Background Technology
[0002] A paper packaging machine is a type of packaging equipment, typically used for packaging bottles. Bottles are continuously conveyed along a conveyor line, and when they pass through a bottle-fed mechanism, they are grouped into sets for subsequent packaging. The bottle-fed mechanism usually includes two conveyor chains, several push rods positioned between the conveyor chains, and a motor that drives the chains. As the conveyor chains rotate, they move the push rods, which separate the continuous bottles into groups. During operation, if bottles tip over, the resistance of the conveyor chains can become excessive, potentially overloading and damaging the motor. Utility Model Content
[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a bottle-carrying mechanism with overload protection that can automatically control the motor to stop when the resistance of the conveyor chain is too large, thus avoiding motor overload damage.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A bottle-driving mechanism with overload protection includes a frame, two conveyor chains mounted on the frame, and a motor driving the conveyor chains. Several bottle-driving rods are arranged between the conveyor chains. The frame has a chain guide rail and a chain limiting member located on one side of the chain guide rail. The conveyor chain passes between the chain limiting member and the chain guide rail. One end of the chain limiting member is rotatably connected to the frame, and the chain limiting member presses against the conveyor chain. The frame has a pressure adjusting member that provides a preset pressure to the chain limiting member. A sensing component for detecting changes in the position of the chain limiting member is provided between the frame and the chain limiting member. When the resistance on the conveyor chain is too great, causing the motor to overload, the conveyor chain tightens, causing the chain limiting member to rotate. The sensing component detects the change in the position of the chain limiting member and controls the motor to stop rotating.
[0006] By adopting the above technical solution, when the chain is obstructed and the motor is overloaded, the sensing component controls the motor to stop rotating by changing the signal, thereby protecting the motor.
[0007] Preferably, the sensing component includes a sensor mounted on the frame and a sensor mounted on the chain limiter; when the motor is moving normally, the position of the sensor corresponds to the position of the sensor; when the motor is overloaded, the sensor separates from the sensor, causing the sensor signal to change.
[0008] Preferably, the chain limiting components are provided in two sets, with each set pressing against one of the two conveyor chains. A rotating shaft is provided on the frame, and one end of each set of chain limiting components is fixedly connected to the rotating shaft. A transmission arm is fixedly mounted on one end of the rotating shaft, and the pressure adjusting component is connected to the transmission arm. The two sets of chain limiting components provide better stability.
[0009] Preferably, the chain limiting member includes a connecting arm and a pressure bar fixed on the connecting arm, and the end of the connecting arm is fixedly connected to the rotating shaft.
[0010] Preferably, the frame is equipped with chain guides at both ends of the chain limiting member. The points of action between the two chain guides and the conveyor chain are designated as points A and B, and the point of action between the chain limiting member and the conveyor chain is designated as point C. Points A, B, and C are not collinear. The two chain guides limit the chain, and the chain limiting member presses against point C. When the chain is taut, it will push the chain limiting member to rotate.
[0011] Preferably, the pressure regulating component includes a cylinder and a pressure regulating valve for controlling the cylinder pressure. One end of the cylinder is rotatably connected to the frame, and the shaft end of the cylinder is rotatably connected to the transmission arm. The pressure of the chain guide on the chain is controlled by preset pressure regulating valve state. When the chain is taut, the chain guide will rotate when the reaction force on the chain guide is greater than the pressure value.
[0012] Preferably, the sensor is configured as either a proximity switch or a reflection sensor.
[0013] Preferably, the frame is equipped with a main shaft driven by a motor, and a drive wheel is fixedly mounted at the end of the main shaft. A transmission shaft is provided on the frame corresponding to the main shaft. Sprockets that mesh with the conveyor chain are fixed at both ends of the transmission shaft. A driven wheel that is poweredly connected to the drive wheel is provided at the end of the transmission shaft. A torque limiter is provided between the driven wheel and the transmission shaft. An inductive switch for detecting changes in the state of the torque limiter is provided on the frame. When the resistance of the conveyor chain is too great, causing the torque to exceed a preset value, the inductive switch detects the abnormal state of the torque limiter and controls the motor to stop rotating.
[0014] Therefore, this utility model has the beneficial effects of preventing motor overload damage and good overall stability. Attached Figure Description

[0018] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.
[0019] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.
[0020] like Figure 1 and Figure 2 The bottle-driving mechanism shown includes a frame 10, two conveyor chains 11 mounted on the frame 10, a motor 12 driving the conveyor chains 11, a plurality of bottle-driving rods 110 between the conveyor chains 11, a chain guide rail 13 mounted on the frame 10, and a chain limiting member 20 mounted on one side of the chain guide rail 13. The conveyor chain 11 passes between the chain limiting member 20 and the chain guide rail 13, and one end of the chain limiting member 20 is rotatably connected to the frame 10. The positioning member 20 presses against the conveyor chain 11. The frame 10 is provided with a pressure regulating member 30 that provides a preset pressure to the chain positioning member 20. A sensing component 4 for detecting changes in the position of the chain positioning member 20 is provided between the frame 10 and the chain positioning member 20. When the resistance of the conveyor chain 11 is too great, causing the motor to overload, the conveyor chain 11 tightens and drives the chain positioning member 20 to rotate. The sensing component 4 detects the change in the position of the chain positioning member 20 and controls the motor 12 to stop rotating.
[0021] The sensing component 4 includes a sensor 40 mounted on the frame and a sensor 21 mounted on the chain limiter 20. When the motor 12 is moving normally, the position of the sensor 21 corresponds to the position of the sensor 40. When the motor is overloaded, the sensor 21 separates from the sensor 40, causing a change in the signal of the sensor 40. In some embodiments, the positions of the sensor 40 and the sensor 21 can be interchanged to achieve the same or equivalent function. The sensor 40 is configured as either a proximity switch or a reflection sensor.
[0022] Two sets of chain limiting members 20 are provided, and the two sets of chain limiting members 20 press on the two conveyor chains 11 respectively. A rotating shaft 22 is provided on the frame 10. One end of each set of chain limiting members 20 is fixedly connected to the rotating shaft 22. A transmission arm 23 is fixedly provided at one end of the rotating shaft 22. The pressure adjusting member 30 is connected to the transmission arm 23. The chain limiting member 20 includes a connecting arm 200 and a pressure strip 201 fixed on the connecting arm 200. The end of the connecting arm 200 is fixedly connected to the rotating shaft 22.
[0023] The pressure regulating component 30 includes a cylinder 300 and a pressure regulating valve 301 for controlling the cylinder pressure. One end of the cylinder 300 is rotatably connected to the frame 10, and the shaft end of the cylinder 300 is rotatably connected to the transmission arm 23.
[0024] Chain guides 14 are provided at both ends of the chain limiter 20 on the frame 10. The points of action between the two chain guides 14 and the conveyor chain 11 are designated as points A and B, and the point of action between the chain limiter 20 and the conveyor chain 11 is designated as point C. Points A, B, and C are not collinear. Points A, B, and C are distributed in a triangle, with point C only subjected to the pressure of the chain guides. When the chain is obstructed, the section of the chain between points A and B is tightened, thereby generating a reaction force on the chain limiter 20. This reaction force overcomes the pressure of the cylinder, causing the chain limiter 20 to rotate around the shaft 22. At this time, the sensor separates from the sensor, the signal of the sensor changes, and thus controls the motor to stop moving.
[0025] like Figure 3 As shown, a main shaft 15 driven by a motor 12 is mounted on the frame 10. A drive wheel 150 is fixed to the end of the main shaft 15. A transmission shaft 16 is mounted on the frame 10 corresponding to the main shaft 15. Sprockets 160 that mesh with the conveyor chain 11 are fixed to both ends of the transmission shaft 16. A driven wheel 161 that is poweredly connected to the drive wheel 150 is mounted at the end of the transmission shaft 16. A torque limiter 17 is provided between the driven wheel 161 and the transmission shaft 16. An inductive switch 18 is provided on the frame 10 to detect changes in the state of the torque limiter 17. When the resistance experienced by the conveyor chain 11 is too great, causing the torque to exceed a preset value, the inductive switch 18 detects an abnormal state of the torque limiter 17 and controls the motor 12 to stop rotating. In this embodiment, the torque limiter 17 is a mechanical torque limiter. When the torque is overloaded, the position of the connecting piece on the mechanical torque limiter will be displaced along the axial direction. The working state of the torque limiter is detected by detecting the position change of the connecting piece through the inductive switch.
[0026] Referring to the accompanying drawings, the principle of this utility model is as follows: When the chain resistance increases, the section of chain between points A and B is tightened, causing the chain limiter 20 to rotate, thereby separating the sensor from the inductor. The inductor detects the signal change and controls the motor to stop; or, when the inductive switch 18 detects an overload of torque in the torque limiter 17, it controls the motor to stop. Either the inductor or the inductive switch will detect a signal and control the motor to stop, thus providing dual protection and better stability.

Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
