Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of packing machines, and relates to an automatic packing machine. BACKGROUND

[0002] In order to realize environmental protection and improve resource utilization efficiency, waste paper and plastic waste and the like are usually recycled. In this process, in order to optimize transportation and reduce logistics costs, the recycled materials usually need to be compressed and packed to reduce the volume and increase the effective load of each transportation.

[0003] For example, a utility model with an application number CN201420859970.2 provides an automatic packing machine, which comprises a rack main body, a pressing mechanism, a line hooking mechanism and a wire twisting device. The rack main body is penetrated by a pressing cavity at both ends, the pressing mechanism is arranged in the pressing cavity, the line hooking mechanism is fixed on one side of the rack main body, the line hooking mechanism is provided with a threading fork capable of vertically penetrating the pressing cavity, and the rack main body is provided with a threading hole on both sides. The wire twisting device is fixed on the other side of the rack main body and covers the threading hole. The wire twisting device comprises a wire cutting mechanism and a wire twisting mechanism. The wire cutting mechanism comprises a wire cutting knife and a wire cutting oil cylinder. The wire twisting mechanism comprises a rotatingly installed wire twisting hook and a wire twisting motor. The wire cutting knife and the wire twisting hook are located on the movement path of the threading fork.

[0004] In summary, although some existing technical solutions solve the problem of waste packing, the threading fork is still in the pressing trolley for a long time during the packing process, which may cause the pressing trolley to retreat due to pressure relief of the pressing cylinder and other reasons, resulting in deviation and jamming of the line hooking rod. Therefore, there is still a large room for improvement. SUMMARY

[0009] A line twisting mechanism is arranged on the same side of the frame as the line hooking mechanism, and comprises a line twisting hook, a line twisting driving element, a plurality of line cutting knife sets, and a line cutting driving element. The line twisting driving element and the line cutting driving element are connected to the mounting frame, the line twisting hook is rotatably connected to the mounting frame, the number of the line twisting hooks is twice the number of the line hooking rods and is located on both sides of the line hooking rods, the line twisting driving element can drive the line twisting hook to rotate relative to the mounting frame, the line cutting knife sets are liftably connected to the mounting frame, the number of the line cutting knife sets is the same as the number of the line hooking rods, and the line cutting driving element can drive the line cutting knife sets to lift relative to the mounting frame.

[0010] In the automatic packing machine, the line hooking rod is provided with an inclined surface and a first pulley. The inclined surface is arranged at one end of the line hooking rod away from the line hooking driving element, and the first pulley is rotatably connected to one end of the line hooking rod away from the line hooking driving element.

[0011] In the automatic packing machine, a limiting clamp is further arranged. The limiting clamp is swingably connected to the mounting frame, the number of the limiting clamps is the same as the number of the line twisting hooks, and the limiting clamps are located on the same horizontal line as the line hooking rods and are respectively located on both sides of the line hooking rods.

[0012] In the automatic packing machine, a limiting clamp is further arranged on the other side of the mounting frame connected to the frame body, and the limiting clamps on the side of the frame body and the side of the mounting frame are aligned.

[0013] In the automatic packing machine, an adjusting nut is further arranged. The frame body and the mounting frame are both provided with adjusting holes, and the adjusting nut is liftably connected to the limiting clamps through the adjusting holes.

[0014] In the automatic packing machine, the line cutting knife set comprises a first knife and a second knife. The first knife is connected to the line cutting driving element, the second knife is connected to the mounting frame, and the line cutting driving element can drive the first knife to move relative to the second knife.

[0015] In the automatic packing machine, the number of the second blades is the same as the number of the wire hook rods, and the number of the first blade is one.

[0016] In the automatic packing machine, the limiting clamp is further provided with a second pulley, which is rotatably connected with the middle part of the limiting clamp.

[0017] In the automatic packing machine, a pushing block is further included, which is slidably connected with the mounting frame, one end of each wire hook rod is connected with the pushing block, and the wire hook driving element can drive the pushing block to slide relative to the mounting frame.

[0018] In the automatic packing machine, a transmission chain is further included, the mounting frame is further provided with a rotating part, two sides of the transmission chain are respectively engaged with the rotating part and the output shaft of the wire hook driving element, and the pushing block is connected with one section of the transmission chain.

[0019] Compared with the prior art, the automatic packing machine has the following beneficial effects:

[0020] 1. Compared with the conventional packing machine, the packing machine is significantly optimized in design, especially the layout of the wire hook mechanism and the wire twisting mechanism.

[0021] 2. The design of the inclined surface not only allows the iron wire to move along the set trajectory through the inclined surface, but also reduces the friction and impact force between the two, ensuring smooth operation throughout the process.

[0022] 3. The limiting clamp can ensure that the iron wire is fixed within a specific height range, ensuring that the iron wire can contact the inclined surface and be taken to the mounting frame side by the wire hook rod, providing a guarantee for subsequent wire twisting operations and increasing the reliability of the packing machine.

[0023] 4. By rotating the adjusting nut, the height of the clamp relative to the limit clamp is changed. Since one end of the limit clamp is in contact with the adjusting nut, the rotation range of the limit clamp can be adjusted, thus accommodating wires of different specifications. This allows the wires to be guided and fixed by the limit clamp and the hook rod, improving the flexibility of the baling machine.

[0024] 5. The first blade adopts an integrated design. Compared with multiple first blades, the movement path and cutting action of a single blade are easier to predict and control, thereby improving the accuracy and consistency of cutting. The integrated design of the first blade can respond to the action command of the tangent drive element more quickly, shortening the time cycle from start to completion of cutting. This not only improves work efficiency, but also saves more time for subsequent operations, improving the smoothness of the entire packaging process. Attached Figure Description

If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0037] The specific embodiments described herein are merely illustrative examples of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the present invention or exceeding the scope defined by the appended claims.

[0038] like Figures 1-5 As shown, an automatic packaging machine includes: a frame body 1, a pressing mechanism 2, a hooking mechanism 3, and a twisting mechanism 4.

[0039] The main body 1 of the frame is provided with a pressing chamber (not shown in the figure), and the top of the main body 1 of the frame is provided with a feed port 11 communicating with the pressing chamber. The main body 1 of the frame is also provided with a wire hole (not shown in the figure).

[0040] The pressing mechanism 2 comprises a pressing trolley 21 and a pressing cylinder 22, the pressing trolley 21 is contained in the pressing cavity, the pressing cylinder 22 is arranged on the rack body 1, and the pressing cylinder 22 can drive the pressing trolley 21 to move in the pressing cavity.

[0041] The hooking mechanism 3 is arranged on the side of the rack body 1, and comprises a mounting frame 31, hooking rods 32 and a hooking driving element 33, the number of the hooking rods 32 is at least two, the mounting frame 31 is connected with the rack body 1, the hooking driving element 33 is connected with the mounting frame 31, the hooking rods 32 are slidably connected with the mounting frame 31, the hooking rods 32 are slidably connected with the rack body 1 through the threading holes, one end of the hooking rods 32 is connected with the hooking driving element 33, and the hooking driving element 33 can drive the hooking rods 32 to move back and forth in the pressing cavity.

[0042] The twisting mechanism 4 is arranged on the same side of the rack as the hooking mechanism, and comprises twisting hooks 41, a twisting driving element 42, a wire cutting knife set 43 and a wire cutting driving element 44, the twisting driving element 42 and the wire cutting driving element 44 are connected with the mounting frame 31, the twisting hooks 41 are rotatably connected with the mounting frame 31, the number of the twisting hooks 41 is twice the number of the hooking rods 32 and is located on both sides of the hooking rods 32, the twisting driving element 42 can drive the twisting hooks 41 to rotate relative to the mounting frame 31, the wire cutting knife set 43 is liftably connected with the mounting frame 31, the number of the wire cutting knife set 43 is the same as the number of the hooking rods 32, and the wire cutting driving element 44 can drive the wire cutting knife set 43 to lift relative to the mounting frame 31.

[0043] Specifically, the waste paper or plastic and the like which need to be packed is put into the feeding port 11, and then slides into the pressing cavity, the pressing trolley 21 is driven by the pressing cylinder 22 to move, the waste in the pressing cavity is compressed to reduce the volume, then the hooking rods 32 are driven by the threading driving element to enter the threading holes until the tips can touch the iron wires which are previously arranged on one side of the mounting frame 31 and the other side of the rack body 1, after the action is completed, the hooking rods 32 continue to return to the initial position along the original path, and at the same time, the iron wires on both ends are successfully taken back to the side of the mounting frame 31 to form a closed loop around the compressed waste, at this time, the twisting hooks 41 on both sides of the hooking rods 32 are driven by the twisting driving element 42 to rotate to twist the iron wires on both sides of the hooking rods 32, after the twisting is completed, the wire cutting knife set 43 is driven by the wire cutting driving element 44 to cut the iron wires, finally, the iron wires after cutting are twisted by the rotation of the twisting hooks 41, at this time, the compression and packing of the waste are completed.

[0044] In the embodiment, compared with the conventional packing machine, the packing machine is significantly optimized in design, especially the layout of the whole hooking mechanism 3 and the twisting mechanism 4. In the conventional packing machine, the hooking rod 32 in the form of a push wire needs to be in the pressurized trolley 21 for a long time, which may cause the pressurized trolley 21 to retreat due to pressure relief of the pressurizing cylinder 22 and other reasons, thereby causing the hooking rod 32 to deviate and jam. The twisting mechanism 4 and the hooking mechanism 3 of the packing machine are arranged on the same side of the rack main body 1. When the wire is twisted, the hooking rod 32 has been retracted to one side of the mounting frame 31, thereby reducing the time of the hooking rod 32 in the pressurized trolley 21, and greatly avoiding damage to the hooking rod 32 caused by pressure relief of the pressurizing cylinder 22. Therefore, the maintenance cost caused by mechanical failure is reduced, and the overall safety and reliability are improved.

[0045] As shown in Figures 1-5 , on the basis of the above embodiment, the hooking rod 32 is provided with an inclined surface 321 and a first pulley 322. The inclined surface 321 is arranged at one end of the hooking rod 32 away from the hooking driving element 33. The first pulley 322 is rotatably connected to one end of the hooking rod 32 away from the hooking driving element 33.

[0046] Specifically, when the hooking rod 32 approaches the wire previously arranged on the rack main body 1, the inclined surface 321 first contacts the wire to offset the wire upward or downward along the inclined surface 321. When the hooking rod 32 returns along the original path, the first pulley 322 contacts the wire to drive the wire back to the side of the mounting frame 31.

[0047] In the embodiment, the design of the inclined surface 321 can not only make the wire move along the set trajectory through the inclined surface 321, but also reduce the friction and impact force that may be generated between the two, thereby ensuring smooth operation of the whole process. The wire offset by the first pulley 322 can be pulled back to adjust the position of the wire while reducing the wear of the wire, thereby prolonging the service life of the wire.

[0048] As shown in Figures 1-5 , on the basis of the above embodiment, a limiting clamp 34 is further included. The limiting clamp 34 is swingably connected to the mounting frame 31. The number of the limiting clamps 34 is the same as that of the wire hooks 41. The limiting clamps 34 are on the same horizontal line as the hooking rods 32 and are respectively located on both sides of the hooking rods 32.

[0049] Specifically, the limiting clamps 34 are arranged on both sides of each hooking rod 32. When the wire is previously arranged on the rack main body 1, the limiting clamps 34 limit the height of the wire, so that the inclined surface 321 can contact the wire when the hooking rod 32 moves.

[0050] In the embodiment, the limiting clip 34 can ensure that the wire is fixed in a specific height range, ensure that the wire can contact the inclined surface 321 and be taken to the mounting rack 31 side by the wire hooking rod 32, provide guarantee for subsequent wire twisting operation, and increase the reliability of the packing machine.

[0051] As shown in the above embodiment, the other side of the rack body 1 connected with the mounting rack 31 is also provided with a limiting clip 34, and the limiting clip 34 on the side of the rack body 1 is aligned with the limiting clip 34 on the side of the mounting rack 31. Figures 1-5

[0052] In the embodiment, the limiting clip 34 is also arranged on the other side of the rack body 1, and the limiting clip 34 on the side of the rack body 1 is aligned with the limiting clip 34 on the side of the mounting rack 31. While ensuring that the height of the wire on the side of the rack body 1 can be contacted by the wire hooking rod 32, the limiting clip 34 on the side of the rack body 1 can also serve as a support point for the wire, ensuring that only the wire in contact with the wire hooking rod 32 is taken to the side of the mounting rack 31.

[0053] As shown in the above embodiment, the other side of the rack body 1 connected with the mounting rack 31 is also provided with a limiting clip 34, and the limiting clip 34 on the side of the rack body 1 is aligned with the limiting clip 34 on the side of the mounting rack 31. Figures 1-5

[0054] Specifically, the adjusting hole 311 is a threaded hole. When the adjusting nut is rotated, the adjusting nut can be raised or lowered relative to the limiting clip 34. When the wire contacts the inclined surface 321, the height of the wire changes, and the limiting clip 34 can swing accordingly. One end of the limiting clip 34 can contact the adjusting nut during the swinging process.

[0055] In the embodiment, the height of the adjusting nut relative to the limiting clip 34 is changed by rotating the adjusting nut. Since one end of the limiting clip 34 contacts the adjusting nut, the rotation amplitude of the limiting clip 34 can be adjusted, and different specifications of wires can be adapted, so that the wires can be guided and fixed by the limiting clip 34 and the wire hooking rod 32, and the flexibility of the packing machine is improved.

[0056] As shown in the above embodiment, the wire cutting knife set 43 includes a first blade 431 and a second blade 432. The first blade 431 is connected with the wire cutting driving element 44, the second blade 432 is connected with the mounting rack 31, and the wire cutting driving element 44 can drive the first blade 431 to move relative to the second blade 432. Figures 1-5

[0057] ​​​In this embodiment, the portion of the wire after stranding is cut using a first blade 431 and a second blade 432. The second blade 432 is fixed to the mounting bracket 31. The wire cutting drive element 44 pushes the first blade 431 towards the second blade 432, thereby cutting the wire between the first blade 431 and the second blade 432. Each set of hook rods 32 corresponds to a set of first blades 431 and second blades 432, thus enabling precise cutting of the wire after stranding.

[0058] like Figures 1-5 As shown, based on the above embodiment, the number of the second blades 432 is the same as the number of the hook rods 32, and the number of the first blades 431 is one.

[0059] In this embodiment, the first blade 431 adopts an integrated design. Compared with multiple first blades 431, the movement path and cutting action of a single blade are easier to predict and control, thereby improving the accuracy and consistency of cutting. The integrated first blade 431 can respond to the action command of the tangent drive element 44 more quickly, shortening the time cycle from start to completion of cutting, which not only improves work efficiency, but also saves more time for subsequent operations and improves the smoothness of the entire packaging process.

[0060] like Figures 1-5 As shown, based on the above embodiment, the limiting clamp 34 is further provided with a second pulley 341, which is rotatably connected to the middle part of the limiting clamp 34.

[0061] In this embodiment, the wire is always in contact with the second pulley 341. As the main support point of the wire, the second pulley 341 plays a guiding role when the hook rod 32 pulls the wire, ensuring that the wire can move smoothly along the surface of the second pulley 341 without causing surface damage due to direct friction. At the same time, the second pulley 341 cooperates with the first pulley 322 to keep the wire in a suitable tension state.

[0062] like Figures 1-5 As shown, based on the above embodiment, it also includes a push block 5, which is slidably connected to the mounting frame 31. One end of each hook rod 32 is connected to the push block 5, and the hook driving element 33 can drive the push block 5 to slide relative to the mounting frame 31.

[0063] In this embodiment, one end of each hook rod 32 is connected to the push block 5. The push block 5 can simultaneously drive multiple hook rods 32 to move synchronously, reducing the error caused by individual hook rods 32 deviating from the predetermined track. At the same time, compared with controlling multiple hook rods 32 separately, this method not only reduces the complexity of control, but also improves the reliability and maintenance convenience of the system.

[0064] As Figures 1-5 shown in the above embodiment, a transmission chain (not shown in the figure) is further included, the mounting frame 31 is further provided with a rotating part 312, two sides of the transmission chain are respectively engaged with the rotating part 312 and the output shaft of the line hook driving element 33, and one segment of the transmission chain is connected with the pushing block 5.

[0065] Specifically, since the two sides of the transmission chain are respectively engaged with the rotating part 312 and the output shaft of the line hook driving element 33, when the output shaft rotates, the transmission chain will rotate along with the rotation of the output shaft, and the rotating part 312 of the mounting frame 31 can rotate accordingly, thereby supporting the position of the transmission chain.

[0066] In the present embodiment, since the transmission chain is connected with the output shaft of the line hook driving element 33 in the form of engagement, the transmission chain can respond to the movement signal of the line hook driving element 33 in time and transmit it to the pushing block 5 connected therewith, thereby driving the pushing block 5 to move reciprocally, ensuring smooth and efficient operation of the whole system.
