Description

Technical Field

[0001] The present invention relates to the technical field of baling machine conveying, and in particular to a cloth bag conveying device and a baling machine. Background Art

[0002] The cloth of a chemical fiber baler usually has two sides, one side is coated with a waterproof film, and the other side is coated with a UV protection film. The upper cloth needs to be laid with the waterproof side facing down, and the lower cloth needs to be laid with the waterproof side facing down. The previous structural design of the cloth conveying device lacked uniformity and standardization. Different parts use a variety of different structural combinations, which requires a variety of processes and parts during the manufacturing process of the device, increasing the difficulty and cost of manufacturing. Moreover, during subsequent maintenance, due to the complexity and diversity of the structure, maintenance personnel need to be familiar with a variety of structural principles, and spend a lot of time and energy to troubleshoot the fault points, resulting in high maintenance costs.

[0003] There is also a cloth conveying device in the prior art that uses a cloth conveying mechanism. The cloth conveying mechanism makes the device structure design extremely complex. Moreover, the low efficiency and complex structure of the cloth conveying device are increasingly difficult to meet the needs. High-volume balers require efficient, stable and easy-to-operate cloth conveying devices. However, due to structural limitations, the current device is time-consuming and labor-intensive when handling the flipping and laying of the cloth, and cannot achieve fast and accurate cloth laying operations. It is difficult to adapt to the packaging needs in the large-scale chemical fiber production process, and has become one of the bottleneck factors restricting the improvement of production efficiency and large-scale development of the chemical fiber industry.

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] Example 1

[0054] Reference Figure 1 to Figure 9 , which is the first embodiment of the present invention, proposes a cloth wrapping conveying device, including a conveying device 200, which has two conveying devices 200, which are arranged on a bracket 100 at intervals along the height direction, and the two conveying devices 200 are respectively a first conveying device 210 and a second conveying device 220 with the same structure. The first conveying device 210 is arranged on the bracket 100, and the first conveying device 210 is used to convey the upper cloth wrapping; the second conveying device 220 is arranged on the bracket 100, and the second conveying device 220 is located below the first conveying device 210, and the second conveying device 220 is used to convey For the lower wrapping cloth, the first conveying device 210 and the second conveying device 220 have the same structure, and both the first conveying device 210 and the second conveying device 220 include: a support frame 110 is set on the bracket 100, and a first clamp 230 is slidably set on the bracket 100, and the first clamp 230 slides close to or away from the wrapping cloth roll 300; the second clamp 240 is slidably set on the bracket 100, and the second clamp 240 slides close to or away from the baler, and a conveying space 250 is provided between the second clamp 240 and the first clamp 230, and the conveying space 250 is used for the wrapping cloth to pass through.

[0055] In the above solution, the bracket 100 provides stable support for the first conveying device 210 and the second conveying device 220. The first clamp 230 can accurately control the length of the cloth pulled out, thereby ensuring the dimensional accuracy of the cloth each time and improving the consistency and quality of the product. The first conveying device 210 and the second conveying device 220 have the same structure, which simplifies the structure of the overall device and reduces the manufacturing and maintenance costs. At the same time, the same structure is also convenient for operators to learn and master, and improves the convenience and versatility of operation.

[0056] The first conveying device 210 and the second conveying device 220 both have a support frame 110, a first clamp 230 and a second clamp 240. The support frame 110 provides stable support for the clamp, ensures the stability of the first clamp 230 and the second clamp 240 during sliding and working, and reduces the size error and conveying failure caused by shaking or instability. The first clamp 230 and the second clamp 240 are both slidably set on the support frame 110. The first clamp 230 is used to clamp the front end of the wrapping cloth, and the wrapping cloth is pulled out of the wrapping cloth roll 300 by sliding to a fixed length, so that part of the wrapping cloth is located in the conveying space 250. The sliding amount of the first clamp 230 can accurately control the length of the wrapping cloth pulled out, thereby ensuring the dimensional accuracy of the wrapping cloth each time, and improving the consistency and quality of the product. The first clamp 230 and the second clamp 240 have clear division of labor, and are responsible for controlling the size and conveying respectively, making the processing flow of the wrapping cloth clearer and more orderly, and reducing the complexity and error rate of the operation.

[0057] In actual use, the first clamp 230 first clamps the front end of the wrapping cloth on the wrapping cloth roll 300, and the first clamp 230 pulls out a fixed length of wrapping cloth from the wrapping cloth roll 300 by sliding, the second clamp 240 clamps the wrapping cloth, and the wrapping cloth is cut by the cutting device, the first clamp 230 releases the wrapping cloth, and the second clamp 240 slides to transport the wrapping cloth. The first clamp 230 and the second clamp 240 are respectively used to control the size and transport of the wrapping cloth, which not only improves the size accuracy of the wrapping cloth each time, but also simplifies the overall structure.

[0058] It should be further explained that the front end of the wrapping cloth refers to the end of the wrapping cloth extending from the wrapping cloth roll 300 away from the wrapping cloth roll.

[0059] Furthermore, the sliding directions of the first clamp 230 and the second clamp 240 are perpendicular.

[0060] In the above solution, the vertical sliding direction of the first clamp 230 and the second clamp 240 can more effectively utilize the space on the support frame 110, making the structure of the device more compact and reducing the floor space. In addition, the vertical sliding direction makes it easier to transport the wrapping cloth and facilitates the arrangement of the first clamp 230 and the second clamp 240.

[0061] A conveying space 250 is provided between the first clamp 230 and the second clamp 240 , which ensures that the first clamp 230 and the second clamp 240 move independently and do not interfere with each other, thereby improving the flexibility and accuracy of the operation.

[0062] Furthermore, the height of the cloth roll 300 is lower than the first clamp 230, and the first conveying device 210 and the second conveying device 220 both include a guide roller 260 rotatably set on the bracket 100, and the guide roller 260 is located on one side of the conveying space 250, and the guide roller 260 is used to guide the cloth on the cloth roll 300 to the conveying space 250; there are two limiting plates 270, both of which are set on the bracket 100, and the two limiting plates 270 are both located on the side of the guide roller 260 close to the conveying space 250, and a limiting space 280 is formed between the two limiting plates 270, and the cloth enters the conveying space 250 after passing through the limiting space 280.

[0063] In the above scheme, the cloth roll 300 is designed to be lower than the first clamp 230, so that the cloth between the cloth roll 300 and the first clamp 230 can be kept in a tensioned state under the action of gravity, ensuring that the cloth in the conveying space 250 is of a fixed length under the pulling of the first clamp 230.

[0064] The guide roller 260 can accurately guide the wrapping cloth on the wrapping cloth roll 300 to the conveying space 250, thereby preventing the wrapping cloth from deviating or folding during the conveying process, thereby ensuring the accuracy and continuity of the wrapping cloth conveying.

[0065] The limiting space 280 formed by the two limiting plates 270 has the function of limiting and arranging the cloth entering the conveying space 250, so that the cloth can enter the conveying space 250 neatly. Moreover, the two limiting plates 270 can play a supporting role after the cloth is cut, preventing the cloth from sagging under the action of gravity after being cut, which affects the clamping of the front end of the cloth by the first clamp 230 on the lower side. The two limiting plates 270 help to improve the accuracy and quality of subsequent processing. Moreover, the setting of the limiting space 280 effectively limits the swing and deviation of the cloth, and reduces the dimensional error and conveying failure caused by the unstable position of the cloth.

[0066] Furthermore, the cutting knife 400 is lifted and lowered on the bracket 100. After being lifted and lowered, the cutting knife 400 approaches or moves away from the conveying space 250. The cutting knife 400 is located between the limiting space 280 and the conveying space 250. The cutting knife 400 is used to cut the wrapping cloth.

[0067] In the above solution, the cutting knife 400 can accurately cut the cloth at the designated position, ensuring the consistency and accuracy of the cutting position, which is conducive to improving the cutting quality of the cloth. The lifting action mode is easy to integrate with the control system of the entire production process, realizes automatic and precise control, and reduces the difficulty and error rate of manual operation. The cutting knife 400 can be raised and lowered on the bracket 100 in a pneumatic manner, which is not only fast in action but also easy to control.

[0068] The cutting knife 400 is heated by a thermocouple, so that the cutting knife 400 performs thermal cutting on the wrapping cloth, which is beneficial to improving the cutting efficiency of the wrapping cloth.

[0069] Example 2

[0070] Reference Figure 4~Figure 5 , which is the second embodiment of the present invention, and which is based on the first embodiment:

[0071] Compared with Example 1, further, the second clamp 240 includes a sliding frame 241 slidably set on the support frame 110, and the sliding frame 241 is located above the first clamp 230; there are four second clamps 242, all of which are set on the sliding frame 241, and the four second clamps 242 are respectively used to clamp the four corners of the cloth in the conveying space 250.

[0072] In this embodiment, the four second clamping jaws 242 respectively clamp the four corners of the wrapping cloth, which can grasp the wrapping cloth more firmly. This not only prevents the wrapping cloth from shifting or falling off during transportation, thereby ensuring the stability of transportation, but also ensures that the wrapping cloth is in a tensioned state when cutting the cloth, thereby ensuring the quality of cutting.

[0073] In actual use, the first clamp 230 pulls out a part of the front end of the wrapping cloth from the wrapping cloth roll 300, so that the wrapping cloth part is located in the conveying space 250, and the four second clamps 242 clamp the four corners of the wrapping cloth in the conveying space 250. The cutting knife 400 rises to cut off the wrapping cloth, and the first clamp 230 releases the cut wrapping cloth in the conveying space 250. The four second clamps 242 drive the wrapping cloth in the conveying space 250 to move toward the baler through the sliding frame 241. After the second clamps 242 bring the wrapping cloth to the specified position of the baler, the second clamps 242 release the wrapping cloth, and the sliding frame 241 slides to move the second clamps 242 to the bottom of the first clamp 230 again, waiting for the first clamp 230 to re-clamp the wrapping cloth to the conveying space 250.

[0074] Example 3

[0075] Reference Figure 6~Figure 7 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

[0076] Compared with Example 1, further, the fixed clamp 290 has two pieces and is arranged on the support frame 110. The second clamp 240 slides close to or away from the fixed clamp 290, and the fixed clamp 290 is used to clamp the two ends of one side of the cloth in the conveying space 250; the second clamp 240 includes a sliding frame 241 that is slidably arranged on the support frame 110, and the sliding frame 241 is located above the first clamp 230; the second clamp 242 has two pieces, both of which are arranged on the sliding frame 241. The second clamp 242 slides close to or away from the fixed clamp 290, and the two second clamps 242 and the two fixed clamps 290 are respectively used to clamp the four corners of the cloth in the conveying space 250.

[0077] In this embodiment, the four corners are clamped by two fixed jaws 290 and two second jaws 242, respectively, providing a more stable and balanced clamping force, ensuring that the cloth will not loosen or shift during transportation and processing, and improving processing accuracy and stability. Because the two fixed jaws 290 and the two second jaws 242 clamp the four corners of the cloth in the conveying space 250, respectively, after the cloth is cut, the first clamp 230 and the fixed jaws 290 release the cloth in the conveying space 250. The sliding frame 241 slides, so that the second jaw 242 clamps the cloth and moves it to the specified position of the baler. During the movement of the second jaw 242 clamping the cloth, the first clamp 230 can pull the front end of the cloth on the cloth roll 300 from the limiting plate 270 again. After the second jaw 242 returns, it can immediately clamp the cloth in the conveying space 250, and clamp it with the two fixed jaws 290 at the four corners of the cloth, waiting for the cutting knife 400 to cut.

[0078] The design of the fixed clamping jaw 290, the second clamping jaw 242 and the sliding frame 241 improves the overall cloth conveying efficiency, which is beneficial to mass production applications.

[0079] It should be further explained that the fixed clamping jaw 290 is located at a side of the second clamping jaw 242 away from the cloth wrapping machine, and the fixed clamping jaw 290 also clamps the end of the cloth in the conveying space 250 away from the baling machine.

[0080] Example 4

[0081] Reference Figure 4~Figure 5 , Figure 9~Figure 10 , which is the fourth embodiment of the present invention, is based on the second embodiment or the third embodiment:

[0082] Compared with Example 2 or Example 3, further, the guide roller 260, the limiting plate 270 of the first conveying device 210 and the guide roller 260, the limiting plate 270 of the second conveying device 220 are respectively located on both sides of the conveying space 250, and the upper wrapping cloth roll 300 and the lower wrapping cloth roll 300 are respectively located on the side of the limiting plate 270 away from the conveying space 250.

[0083] In the above scheme, the layout on both sides makes the conveying process of the upper and lower wrapping cloths independent of each other, avoiding interference or entanglement between the two during the conveying process, ensuring the smoothness and accuracy of the conveying. In addition, the positions on both sides of the conveying space 250 are fully utilized, making the structure of the entire device more compact and saving installation space.

[0084] In actual use, the wrapping cloth rolls 300 are respectively located on both sides of the bracket 100. The two wrapping cloth rolls 300 are rotated 180 degrees so that when the wrapping cloth is torn off the wrapping cloth rolls 300, the wrapping cloth can be in two states, one facing upward or downward as required for packaging.

[0085] Furthermore, a notch 271 is formed on one side of the limiting plate 270 close to the conveying space 250 , and the notches 271 of the two limiting plates 270 are connected, so that the first clamp 230 can slide into or leave the notch 271 .

[0086] In the above scheme, the side of the limiting plate 270 close to the conveying space 250 has a notch 271, and the notches 271 of the two limiting plates 270 are connected. After the cutting knife 400 rises and cuts the cloth from between the limiting space 280 and the conveying space 250, the front end of the cloth connected to the cloth roll 300 may sag under the action of gravity. When the first clamp 230 slides close to the front end of the cloth to clamp, the clamping position may be unfixed due to the unfixed position of the front end of the cloth, thereby affecting the size of the cloth. The first clamp 230 enters the notch 271 and clamps the cloth. Combined with the supporting function of the limiting plate 270 for the cloth, the first clamp 230 can clamp the cloth of the same size each time to ensure the utilization rate of the cloth.

[0087] Example 5

[0088] Reference Figure 9~Figure 10 , which is the fifth embodiment of the present invention, is based on the fourth embodiment:

[0089] Compared with Example 4, it further includes a lifting card plate 500, which is lifted and arranged on the bracket 100. After being lifted and lowered, the lifting card plate 500 is close to or away from the conveying space 250, and the lifting card plate 500 is located between the guide roller 260 and the limit plate 270; a fixed plate 600 is arranged on the bracket 100, and the fixed plate 600 is located above the lifting card plate 500. After being lifted and lowered, the lifting card plate 500 abuts against the fixed plate 600, and the lifting card plate 500 and the fixed plate 600 are used to clamp or loosen the wrapping cloth.

[0090] In this embodiment, the lifting clamping plate 500 cooperates with the fixing plate 600 to firmly clamp the wrapping cloth when needed, thereby preventing the wrapping cloth connected to the wrapping cloth roll 300 from sliding toward the wrapping cloth roll 300 under the action of gravity after being cut by the cutting knife 400.

[0091] During use, before the cutting knife 400 rises to cut the wrapping cloth, the lifting clamp 500 rises first and clamps the wrapping cloth with the fixing plate 600. After the wrapping cloth is cut off, the wrapping cloth in the limiting space 280 will not slip. When the first clamp 230 clamps the front end of the wrapping cloth connected to the wrapping cloth roll 300, the lifting clamp 500 descends to release the wrapping cloth, so that the wrapping cloth can be pulled by the first clamp 230.

[0092] The lifting card plate 500 is lifted and lowered on the bracket 100 by using a cylinder, and a rubber pad can be added to a section of the lifting card plate 500 close to the fixed plate 600 to prevent the lifting card plate 500 from damaging the wrapping cloth.

[0093] Example 6

[0094] Reference Figure 1 , Figure 8 , which is the sixth embodiment of the present invention, and this embodiment is different from the fifth embodiment in that:

[0095] Compared with Example 4, it also includes a plurality of groups of one-way valve plates 700, and the plurality of groups of one-way valve plates 700 are all arranged on the limiting plates 270. The plurality of groups of one-way valve plates 700 are linearly distributed along the sliding direction of the second clamp 240. The one-way valve plates 700 are used to prevent the front end of the wrapping cloth from moving away from the conveying space 250. Each group of one-way valve plates 700 has two elastic plates 710, and the two elastic plates 710 have a first end 711 and a second end 712. The first ends 711 of the two elastic plates 710 are respectively arranged on the two limiting plates 270, and the second ends 712 of the two elastic plates 710 abut against each other, and the second end 712 is closer to the conveying space 250 than the first end 711.

[0096] In this embodiment, compared with the method of clamping the cloth by relying on the lifting clamp 500 in Example 5, the one-way valve plate 700 does not need to utilize an additional driving device. When the first clamp 230 clamps the front end of the cloth connected to the cloth roll 300, the first clamp 230 can clamp the cloth so that the front end of the cloth moves from the first end 711 to the second end 712. After the cutting knife 400 cuts off the cloth, the one-way valve plate 700 can give the cloth a certain friction force to prevent the cloth from sliding away from the conveying space 250.

[0097] It should be further explained that the one-way valve plate 700 and the notch 271 on the limit plate 270 are arranged alternately to prevent the first clamp 230 from interfering with the one-way valve plate. The second end 712 of each one-way valve plate 700 has a flexible friction layer, which can generate friction with the wrapping cloth on the one hand and prevent the wrapping cloth from being damaged on the other hand.

[0098] A baling machine, characterized in that it includes a cloth conveying device, and also includes a baling device arranged on one side of a bracket, the cloth conveying device is used to convey the cloth to the baling device, and the second clamp 240 slides close to or away from the baling device.

[0099] In this embodiment, the wrapping cloth conveying device is used to convey the wrapping cloth to the baler. The second clamp 240 slides closer to or away from the baler. The baler is provided with a slide groove so that the second clamp 240 can pass through the slide groove, making it convenient for the second clamp 240 to place the upper wrapping cloth or the lower wrapping cloth directly above or below the extrusion chamber of the baler.

[0100] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
