Description

Technical Field

[0001] This invention relates to the field of overhead conveying systems, and more specifically, to an intelligent overhead conveying device and method for plastic bag processing. Background Technology

[0002] The production process of plastic bags mainly includes three steps: mixing, film blowing, and bag making. First, plastic granules are thoroughly mixed with color masterbatch and other performance-enhancing raw materials in a mixing mixer to ensure uniformity of color and performance. Next, the mixed granules are sucked into a film blowing machine, heated and melted, and blown into cylindrical film tubes. After cooling, the film tubes are rolled into rolls, also known as film rolls. Finally, the film rolls are fed into a bag making machine, cut into specific shapes by mechanical blades, and sealed at the bottom with hot blades. The rolls are then output to a conveyor belt in preset quantities.

[0003] Currently, the mixing process is mostly done manually. Since the plastic granules are all purchased, the weight and volume of each bag are fixed. Manual feeding allows for precise control of the amount of plastic granules, color masterbatch, and other performance-enhancing materials fed into the mixing mixer. However, manual feeding is costly and inefficient, resulting in low production efficiency and low economic returns. Summary of the Invention

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 3 As shown, an intelligent suspended conveyor device for plastic bag processing includes: The suspended circulating conveyor mechanism 1 includes a ring-shaped circulating moving component, a drive component 1 mounted on the ring-shaped circulating moving component, and a plurality of suspension connectors 112 equidistantly connected to the ring-shaped circulating moving component. The drive component 1 is used to drive the ring-shaped circulating moving component to move cyclically along a set path. Adjustable clamping mechanism 2 includes a spacing adjustment component detachably connected to the corresponding suspension connector 112 and two sets of clamping components mounted on the spacing adjustment component. The spacing adjustment component is used to adjust the spacing between the two sets of clamping components. Rotation mechanism 3 includes a rotation component movably connected to the spacing adjustment component and a drive component 2 fixedly installed on the spacing adjustment component. The drive component 2 is used to drive the rotation component to rotate around its own central axis by a set angle. The telescopic buffer mechanism 4 includes a buffer component fixedly connected to the rotating component, a telescopic expansion component connected to the buffer component, and a cutter 406 connected to the upper opening of the telescopic expansion component. The cutter 406 is used to cut the raw material packaging bag, the expansion component is used to adjust the raw material storage capacity of the buffer component, and the buffer component is used to buffer the raw material and discharge the buffered raw material in a quantitative manner.

[0020] It should be noted that the process of automating and precisely controlling the feeding amount using the intelligent overhead conveyor device for plastic bag processing, as described above, includes the following steps: Step 1: Based on the mixing parameters, design a corresponding number of adjustable clamping mechanisms 2, rotating mechanisms 3 and telescopic buffer mechanisms 4 and install them onto the corresponding suspension connector 112. Step 2: Drive the ring-type circulating moving component along the set path until the corresponding suspension connector 112 moves to the loading position, and lift the raw material packaging bag to the corresponding adjustable clamping mechanism 2 through the lifting device. Step 3: Adjust the distance between the two sets of clamping components using the spacing adjustment component to fit the size of the corresponding raw material packaging bag, and then clamp the raw material packaging bag using the clamping components; Step 4: Drive the rotating component to rotate at a set angle using the second drive component, so that the telescopic buffer mechanism 4 connected to the rotating component moves to directly below the raw material packaging bag; Step 5: Based on the parameters of the raw material packaging bag, drive the telescopic expansion component to move a set distance toward the raw material packaging bag. During this process, the raw material packaging bag is cut by the cutter 406, so that the raw material is buffered in the buffer space formed between the buffer component and the telescopic expansion component. Step 6: When the buffer component containing the raw materials moves to the feeding position along with the ring-shaped circulating moving component, the set amount of raw materials is fed into the mixing mixer through the buffer component. This enables automated suspended conveying of raw materials and allows for precise control of the amount of raw materials fed in, making it suitable for raw material packaging bags of different specifications.

[0021] In an optional embodiment of the invention, such as Figure 1 and Figure 2As shown, the ring-type circulating moving assembly includes several equidistantly distributed support beams 101, crossbeams 102 connected to the support beams 101, several fixed connectors 103 connected to the crossbeams 102, an annular track 104 surrounding the several support beams 101, and an annular sliding chain slidably connected to the annular track 104. Several suspension connectors 112 are equidistantly connected to the annular sliding chain. The annular track 104 and several fixed connectors 103 are all fixedly connected. A drive assembly is fixedly installed on the annular track 104, and the annular track 104 is provided with a through groove that cooperates with the drive assembly.

[0022] The drive assembly includes a mounting bracket 105 fixedly connected to the annular track 104, an integrated motor 106 fixedly mounted on the mounting bracket 105, a timing pulley 108 and a timing pulley 109 movably connected to the mounting bracket 105, a transmission assembly 107 connected between the output shaft end of the integrated motor 106 and the timing pulley 108, a timing belt 110 connected between the timing pulley 108 and the timing pulley 109, several balance frames 111 fixedly connected to the mounting bracket 105, an adjusting screw 113 threadedly connected to the balance frame 111, and a pressure applying member 114 connected to the adjusting screw 113. The pressure applying member 114 is used to apply a set pressure to the timing belt 110, which passes through a groove and contacts the annular sliding chain.

[0023] It should be noted that, as mentioned above, when the drive component drives several suspension connectors 112 to move cyclically along a set path, the integrated motor 106 drives the synchronous pulley 108 to rotate. When the synchronous pulley 108 rotates, it works with the synchronous pulley 109 to drive the synchronous belt 110 to rotate cyclically. The area where the synchronous belt 110 contacts the pressure component 114 is subjected to the pressure applied by the pressure component 114, thereby generating a set value of friction between the synchronous belt 110 and the annular sliding chain. As a result, during the cyclic rotation, the synchronous belt 110 continuously pushes the annular sliding chain to move along the fixed moving track path of the annular track 104, and drives the multiple suspension connectors 112 connected to it to move synchronously. This allows the adjustable clamping mechanism 2 connected to the suspension connectors 112 to move synchronously with the suspension connectors 112. The number and spacing of the suspension connectors 112 can be adaptively adjusted according to actual production needs, such as the type of raw materials, the amount of raw materials input, and the specifications of the raw material packaging bags, thereby optimizing the conveying efficiency.

[0024] In an optional embodiment of the invention, such as Figure 3As shown, the spacing adjustment assembly includes a second suspension connector 201, a mounting plate 202 fixedly connected to the second suspension connector 201, two limiting slide grooves 203 symmetrically arranged on the mounting plate 202, a bidirectional screw 204 movably mounted on the mounting plate 202, a limiting slider 205 slidably connected to the inner wall of the limiting slide groove 203, an integrated motor 206 fixedly connected to the mounting plate 202, and a transmission assembly 207 connecting the integrated motor 206 and the bidirectional screw 204. The other end of the bidirectional screw 204 passes through the two limiting slide grooves 203 in sequence, and both limiting sliders 205 are threadedly connected to the bidirectional screw 204. The bidirectional screw 204 is provided with threads of opposite directions.

[0025] The clamping assembly includes a mounting plate 208 fixedly connected to a limiting slider 205, a limiting groove 2 located at the bottom of the mounting plate 208, two limiting sliders 2 symmetrically slidably connected to the inner walls of the limiting grooves 2, a clamping plate 209 fixedly connected to the limiting sliders 2, a bidirectional screw 2 movably connected to the inner wall of the limiting grooves 2, and an integrated motor 3 211 fixedly connected to the mounting plate 208. The output end of the integrated motor 3 211 is fixedly connected to one end of the bidirectional screw 2. Both limiting sliders 2 are threadedly connected to the bidirectional screw 2. The bidirectional screw 2 has threads with opposite directions of rotation. One clamping plate 209 has several nail bodies 210 fixedly connected to it, and the other clamping plate 209 has several nail holes that mate with the nail bodies 210.

[0026] It should be noted that, as mentioned above, due to different manufacturers of raw materials, there may be different packaging specifications for the same or different raw materials. Therefore, it is necessary to adjust the distance between the clamping components according to the different specifications of the packaging bags to ensure stable clamping of the packaging bags. Specifically, after the integrated motor 206 is started, it drives the bidirectional screw 204 to rotate through the transmission component 207. When the bidirectional screw 204 rotates, the threads on the rod body located in the two limit slide grooves 203 areas are in opposite directions. Therefore, during rotation, the two limit sliders 205 can be driven to move closer or further apart, thereby adjusting the distance between the two sets of clamping components. When the distance between the two sets of clamping components is adjusted to the corresponding distance, the integrated motor 3 211 drives the bidirectional screw 2 to rotate. When the bidirectional screw 2 rotates, it drives the two limit sliders 2 to move closer together, thereby driving the two clamping plates 209 to move closer together, thus clamping the packaging bag. The setting of the nail body 210 and nail hole can make the clamping of the packaging bag more stable.

[0027] In an optional embodiment of the invention, such as Figure 3As shown, the rotating assembly includes a limiting shaft 301 movably connected to the mounting plate 202, a driven wheel 302 fixedly connected to the upper end of the limiting shaft 301, and a buffer assembly fixedly connected to the lower end of the limiting shaft 301.

[0028] The second drive assembly includes a second mounting bracket 303 fixedly mounted on a first mounting plate 202, an integrated motor 304 fixedly mounted on the second mounting bracket 303, and a drive wheel 305 connected to the output shaft end of the integrated motor 304. The drive wheel 305 is in contact with the driven wheel 302.

[0029] It should be noted that, as mentioned above, when the packaging bag is clamped and limited, the integrated motor 304 drives the drive wheel 305 to rotate. When the drive wheel 305 rotates, it drives the driven wheel 302 to rotate. When the driven wheel 302 rotates, it drives the limiting shaft 301 to rotate by a set angle, so that the telescopic buffer mechanism 4 can move away from directly under the clamping component. This allows the raw material packaging bag to be lifted to the clamping area of ​​the clamping component, and the empty raw material packaging bag can also be detached. Then, the integrated motor 304 drives the drive wheel 305 to reverse, thereby driving the limiting shaft 301 to reset, so that the telescopic buffer mechanism 4 can move back to directly under the raw material packaging bag.

[0030] In an optional embodiment of the invention, such as Figure 3 As shown, the buffer assembly includes a fixed support plate 401, a funnel 402 fixedly connected to the fixed support plate 401, and an electrically controlled valve 407 installed on the output end of the funnel 402. The fixed support plate 401 is fixedly connected to the lower end of the limiting shaft 301.

[0031] The telescopic expansion assembly includes a bellows 403 connected to the upper opening of the funnel 402, a sliding plate 404 fixedly connected to the upper end of the bellows 403, and an electric telescopic rod 405 connected between the sliding plate 404 and the fixed support plate 401. The sliding plate 404 is provided with a through hole that cooperates with the limiting shaft 301. The cutter 406 is fixedly connected to the upper opening of the bellows 403.

[0032] It should be noted that, as mentioned above, due to the different specifications and input quantities of raw material packaging bags, a telescopic buffer mechanism 4 is set up to achieve precise control of the input quantity of raw materials. When the raw material packaging bag is clamped, the upper opening of the corrugated pipe 403 is moved towards the raw material packaging bag by the electric telescopic rod 405, so that the cutter 406 can cut the raw material packaging bag from the bottom. The raw material can slide from the cut into the buffer area formed between the corrugated pipe 403 and the funnel 402. Due to the different specifications of the packaging table and the different amounts of raw materials, when the packaging bag is long and a lot of raw material slides out, if the height of the corrugated pipe 403 is still maintained at the cutting height, it may cause excessive accumulation of raw material and spillage from the corrugated pipe 403 and the packaging bag. The material overflows from the gaps between the funnel 402 and the corrugated pipe 403 and falls from the opening edge, affecting the accuracy of the feeding amount. At this time, the height of the opening at the upper end of the corrugated pipe 403 can be further adjusted by the electric telescopic rod 405, so that the volume between the funnel 402 and the corrugated pipe 403 can be adapted to the raw material packaging bags of different specifications, making the release of raw materials more stable. When the amount of raw material in the packaging bag gradually decreases, the electric telescopic rod 405 can be used to continuously drive the opening end of the corrugated pipe 403 to move up and down quickly back and forth, thereby driving the cutter 406 to continuously shake the bottom of the packaging bag, which can effectively shake off the raw material that may remain at the corners of the packaging bag, thereby improving the raw material utilization rate and improving the high-precision control of automation.

[0033] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
