Description

TECHNICAL FIELD

[0001] The utility model relates to bagging machine equipment technical field, especially a kind of clamp lifting device for bagging machine. BACKGROUND

[0002] In material packaging industry, the link that pocket receives material and falls off from bag clamp is crucial. After pocket falls off from bag clamp, it needs to fall smoothly on the conveying belt below, which requires clamp to clamp pocket in time. However, the size of pocket used in actual production is various, in order to ensure that clamp can accurately clamp pocket of different sizes, clamp must have the function of lifting. At present, the lifting device used in prior art is to realize the overall lifting of clamp by four lifting cylinders. In ideal state, four cylinders work cooperatively to realize the stable lifting of clamp, and meet the clamping demand of pocket of different sizes.

[0003] However, in actual operation process, this lifting mechanism based on four lifting cylinders exposes many serious problems. First, the synchronous movement of four cylinders is difficult to ensure completely consistent. Due to the influence of factors such as manufacturing accuracy, internal friction and air source pressure fluctuation, different synchronization conditions are prone to occur in lifting process, which leads to the inclination of clamp in lifting, so that pocket cannot be accurately clamped, and even pocket may fall off, which seriously affects production efficiency and product quality. Second, the cost of this lifting mechanism is high. Not only the procurement cost of four cylinders is not low, but also the air source equipment, control system and other supporting equipment increase the overall cost investment. At the same time, the energy consumption is large. Four cylinders work simultaneously to consume a large amount of compressed air, which increases the energy cost of enterprise. In addition, jamming phenomenon often occurs, which may be caused by reasons such as wear of internal parts of cylinder, poor lubrication or entry of external impurities into cylinder. Once jamming phenomenon occurs, production is forced to stop, and maintenance is needed, which greatly affects the continuity and stability of production, and brings economic loss to enterprise. Based on the defects of prior art, the utility model is committed to providing a new clamp lifting device for bagging machine to realize reliable and stable lifting operation without stop, and reduce energy consumption.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Figure 1 A perspective view of a clamp lifting device for a bag-loading machine provided in an exemplary embodiment of the present invention is shown. Figure 2 This invention provides a front view of a clamp lifting device for a bag-loading machine according to an exemplary embodiment of the present invention. Figure 3 The illustration shows a side view of a clamp lifting device for a bag-feeding machine according to an exemplary embodiment of the present invention. The clamp lifting device 1 for the bag-feeding machine is used to drive the clamp 2 to move up and down. The clamp lifting device 1 for the bag-feeding machine includes: a mounting base 11, a lifting cylinder 12, a transmission assembly 13, and a guide assembly 14. The mounting base 11 is mounted on the frame of the bag-feeding machine; the lifting cylinder 12 is mounted on the mounting base 11; the transmission assembly 13 is connected to the piston rod of the lifting cylinder 12 and the clamp 2 respectively, and is used to drive the clamp 2 to move up and down; the guide assembly 14 is connected to the frame of the bag-feeding machine and the clamp 2 respectively, and is used to provide guidance when the clamp 2 moves up and down.

[0038] In this embodiment, the clamp lifting device 1 for the bag-feeding machine plays a crucial role in the entire bag-feeding machine, specifically designed to drive the clamp 2 in efficient and stable lifting movements. The mounting base 11 serves as the foundation support for the entire device, firmly installed on the frame of the bag-feeding machine, providing a stable mounting platform for subsequent components and ensuring a tight fit between the lifting device and the frame, thus guaranteeing stability during operation. The lifting cylinder 12 is the power source for driving the clamp 2 to lift and lower. Mounted on the mounting base 11, it uses internal air pressure to drive the piston rod in linear motion, providing power for the lifting and lowering of the clamp 2.

[0039] Furthermore, the transmission assembly 13 includes: a rotating shaft 131, a first rotating arm 132, and a second rotating arm 133. Both ends of the rotating shaft 131 are rotatably mounted on the mounting base 11. The first end of the first rotating arm 132 is hinged to the piston rod of the lifting cylinder 12, and the second end of the first rotating arm 132 is fixedly sleeved on the middle of the rotating shaft 131. The first end of the second rotating arm 133 is fixedly sleeved on the rotating shaft 131, and the second end of the second rotating arm 133 is hinged to the first end of the lifting rod 134. The second end of the lifting rod 134 is hinged to the connecting seat 135 mounted on the clamp 2.

[0040] In one example, the two ends of the shaft 131 are rotatably mounted on the mounting base 11 via bearing seats.

[0041] In one example, there are two second rotating arms 133, located on either side of the first rotating arm 132.

[0042] In one example, the first end of the first rotating arm 132 is hinged to the piston rod of the lifting cylinder 12 via a bearing and a pin. The second end of the second rotating arm 133 is hinged to the first end of the lifting rod 134 via a bearing and a pin. The second end of the lifting rod 134 is hinged to the connecting seat 135 via a bearing and a pin.

[0043] In this embodiment, the transmission assembly 13 plays a crucial role in converting the linear motion of the lifting cylinder 12 into the lifting motion of the clamp 2. It consists of a rotating shaft 131, a first rotating arm 132, and a second rotating arm 133. Both ends of the rotating shaft 131 are rotatably mounted on the mounting base 11 via bearing seats. This not only ensures the flexibility of the rotating shaft 131's rotation but also effectively reduces friction during rotation, improving transmission efficiency and the device's service life. The first end of the first rotating arm 132 is hinged to the piston rod of the lifting cylinder 12 via a bearing and a pin. This connection method ensures both flexible rotation between the two and reliable power transmission. When the piston rod of the lifting cylinder 12 extends or retracts, it drives the first rotating arm 132 to rotate around the rotating shaft 131. The second end of the first rotating arm 132 is fixedly sleeved on the middle of the rotating shaft 131, thereby transmitting its own rotation to the rotating shaft 131. Two second rotating arms 133 are located on either side of the first rotating arm 132. Their first ends are also fixedly sleeved on the rotating shaft 131. When the rotating shaft 131 rotates, the second rotating arms 133 rotate accordingly. The second end of the second rotating arm 133 is hinged to the first end of the lifting rod 134 via a bearing and a pin. The second end of the lifting rod 134 is also hinged to the connecting seat 135 mounted on the clamp 2 via the same connection method. This converts the rotation of the second rotating arm 133 into the up-and-down movement of the lifting rod 134, thereby driving the clamp 2 to lift and lower. This transmission structure is rationally designed. Through the coordinated action of multiple components, the power of the lifting cylinder 12 is effectively and accurately transmitted to the clamp 2, achieving smooth and reliable lifting and lowering of the clamp 2.

[0044] Furthermore, the guide assembly 14 includes a guide rod 141 and a guide block 142. The first end of the guide rod 141 is connected to the clamp 2, and the second end of the guide rod 141 has a limiting ring 143. The guide block 142 is slidably connected to the guide rod 141 and is connected to the frame of the bag-loading machine.

[0045] In one example, there are four guide components 14, located at the top four corners of the clamp 2.

[0046] In this embodiment, the guide assembly 14 precisely guides the lifting and lowering movement of the clamp 2, ensuring that the clamp 2 maintains a linear motion during lifting and lowering, and avoiding swaying or deviation. It consists of a guide rod 141 and a guide block 142. The first end of the guide rod 141 is connected to the clamp 2, and the second end of the guide rod 141 is provided with a limit ring 143. The limit ring 143 prevents the guide rod 141 from dislodging from the guide block 142, ensuring the stability of the guidance. The guide block 142 is slidably connected to the guide rod 141 and connected to the frame of the bag-feeding machine, allowing the clamp 2 to move linearly along the direction of the guide rod 141 during lifting and lowering. Furthermore, there are four guide assemblies 14, located at the four top corners of the clamp 2. This layout further enhances the stability and accuracy of the guidance, ensuring that the clamp 2 remains horizontal during lifting and lowering, and accurately completes the clamping action on the pocket.

[0047] Next, the working principle of a clamp lifting device for a bag-loading machine involved in the embodiments of this utility model will be explained.

[0048] When the lifting cylinder 12 starts working, the internal air pressure drives the piston rod to perform linear extension and retraction motion;

[0049] When the piston rod performs linear extension and retraction, it will drive the first rotating arm 132, which is hinged to it, to rotate around the rotating shaft 131.

[0050] When the first rotating arm 132 rotates around the rotating shaft 131, it will drive the rotating shaft 131 to rotate together;

[0051] When the rotating shaft 131 rotates, it will drive the second rotating arm 133 to rotate as well;

[0052] When the second rotating arm 133 rotates, it will drive the lifting rod 134, which is hinged to it, to move up and down in a straight line.

[0053] Finally, the vertical linear motion of the lifting rod 134 is transmitted to the clamp 2, thereby driving the clamp 2 to achieve lifting and lowering motion. When the clamp 2 is lifting and lowering, the guide rod 141 will slide in the guide block 142 to provide precise guidance for the clamp 2, ensuring that the clamp 2 lifts and lowers smoothly along a straight line and avoids shaking or deviation. The limiting ring 143 prevents the guide rod 141 from coming out of the guide block 142, further ensuring the stability of the guide.

[0054] In summary, this technical solution includes a mounting base, a lifting cylinder, a transmission assembly, and a guide assembly. The mounting base is installed on the frame of the bag-feeding machine; the lifting cylinder is installed on the mounting base; the transmission assembly is connected to the piston rod of the lifting cylinder and the clamp, respectively, to drive the clamp to lift and lower; the guide assembly is connected to the frame of the bag-feeding machine and the clamp, respectively, to provide guidance during the lifting and lowering of the clamp. In this configuration, the clamp lifting device for the bag-feeding machine achieves reliable, stable, and continuous lifting operations while reducing energy consumption.
