Description

Technical Field

[0001] The invention relates to the technical field of cellulose production lines, and in particular to automatic cotton bale opening and feeding equipment. Background Art

[0002] Refined cotton is non-toxic, odorless, and easy to absorb water. It is the main material for manufacturing ether cellulose (such as CMC, HEC, HPMC, MC, etc.), nitrocellulose (nitrocellulose) and cellulose acetate. It is widely used in many fields such as food, medicine, daily chemicals, plastics, electronics, papermaking, metallurgy, aerospace, etc., and is known as "special industrial monosodium glutamate". When traditional refined cotton bales are used in downstream applications, they are first cut and packaged manually, and then combed, crushed and other raw material pretreatments are carried out.

It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] like Figures 1 to 11As shown, this embodiment provides an automatic cotton bale opening and feeding device for automatically separating the outer garment 101 of the cotton bale and the cotton material 102 in the outer garment 101. The automatic cotton bale opening and feeding device comprises a conveyor line 1 and a belt cutting mechanism 2. The conveyor line 1 is used to convey the cotton bale 100 to be opened along a first direction, and the first direction is the conveying direction of the conveyor line 1; the belt cutting mechanism 2 is arranged above the conveyor line 1, and the belt cutting mechanism 2 is used to cut the packing rope 103 of the cotton bale 100 to be opened on the conveyor line 1. When the cotton bale 100 to be opened is conveyed to the place directly below the belt cutting mechanism 2, it stops in place, and the belt cutting mechanism 2 cuts the packing rope to facilitate the subsequent separation of the outer garment 101 and the fabric.

[0050] Specifically, the conveyor line 1 includes a conveyor support and a plurality of conveyor rollers rotatably arranged on the conveyor support, the plurality of conveyor rollers are arranged in parallel and spaced apart along a first direction, and the cotton bales 100 to be opened move on the conveyor rollers. More specifically, the conveyor line 1 also includes a conveyor drive source and a transmission assembly, the conveyor drive source drives the transmission assembly, and the transmission assembly is connected to the conveyor rollers to drive the conveyor rollers to rotate. More specifically, the conveyor drive source includes a drive motor, and the transmission assembly includes a plurality of transmission gears, one end of each conveyor roller is coaxially connected to a gear shaft, and a transmission dimension is meshed between each two adjacent gear shafts, and a transmission gear is driven to rotate by the drive motor, which drives the gear shaft to rotate, thereby driving the conveyor rollers to rotate synchronously, so as to realize the conveyance of the cotton bales 100 to be opened on the conveyor rollers.

[0051] Preferably, the spacing between two adjacent conveying rollers is greater than the cross-sectional size of the baling rope 103. For example, the spacing between two adjacent conveying rollers is 270 mm. After the baling rope 103 is cut off by the belt cutting mechanism 2, the baling rope 103 slides downward and falls from the gap between the conveying rollers, thereby preventing the baling rope 103 from staying on the conveying rollers and affecting the conveying movement of the cotton bale 100 to be opened.

[0052] More preferably, if Figure 2 As shown, a packing rope collecting frame 11 is also provided below the conveying rollers, and the packing rope 103 dropped from the gap between the conveying rollers falls into the packing rope collecting frame 11, which is convenient for centralized processing and saves cleaning time.

[0053] Specifically, Figure 2 and Figure 3As shown, the tape cutting mechanism 2 includes a tape cutting bracket 21, a tape cutting displacement module 22 and a tape cutting tool 23. The tape cutting bracket 21 is arranged on one side of the conveyor line 1, the tape cutting displacement module 22 is arranged on the tape cutting bracket 21 and is located above the conveyor line 1, and the tape cutting tool 23 is arranged at the output end of the tape cutting displacement module 22. The tape cutting displacement module 22 is used to drive the tape cutting tool 23 to move in the horizontal direction and the height direction to drive the tape cutting tool 23 to approach or move away from the packing rope 103. The tape cutting tool 23 is used to cut the packing rope 103. When the cotton bale 100 to be opened is transported to the bottom of the tape cutting mechanism 2 and stops, the tape cutting displacement module 22 drives the tape cutting tool 23 to adjust its position in the horizontal direction so that the tape cutting tool 23 is aligned with the starting cutting position, for example, aligned with the rope segment at the edge of the baling rope 103; then the tape cutting tool 23 is driven to move downward to approach the cotton bale 100 to be opened until it contacts the baling rope 103; the tape cutting displacement module 22 drives the tape cutting tool 23 to move, so that the tape cutting tool 23 can cut the baling rope 103.

[0054] The tape cutter is a dust collecting type cutting knife, and it cuts at a single point. Of course, in other embodiments, the tape cutter 23 can be other types of cutting knives, for example, including a first drive motor and a first blade driven by the first drive motor, and the first drive motor drives the first blade to rotate, so as to quickly and accurately cut the baling rope 103 it contacts. The dust collecting type cutting knife, equipped with a vacuum cleaner component, cuts at a single point, and does not continuously cut.

[0055] Exemplarily, when the cotton bale 100 to be opened is placed on the conveyor line 1, the length direction of each circle of packing rope 103 thereon is consistent with the axial direction of the conveying roller, the belt cutting displacement module 22 includes a first linear moving module and a second linear moving module arranged at the driving end of the first linear moving module, the belt cutting tool 23 is arranged at the driving end of the second linear moving module, the driving direction of the first linear moving module is the first direction, and the driving direction of the second linear moving module is the height direction. The belt cutting tool 23 is driven to move along the first direction by the first linear moving module, so that the belt cutting tool 23 cuts off each circle of packing rope 103 in sequence along the first direction. Among them, the first linear moving module and the second linear moving module can be selected as a screw type linear module or a synchronous belt type linear module.

[0056] In this embodiment, a visual system is provided on the conveyor line 1, and the visual system is used to take pictures and record the position parameters of the packing rope 103. The conveyor line 1 transports the cotton bale 100 to be opened to the bottom of the belt cutting mechanism 2 according to the record of the visual system, so that the rope segment of the packing rope 103 at the edge is directly opposite to the cutting starting point of the belt cutting mechanism 2. It should be noted that the automatic cotton bale opening and feeding equipment also includes a control module, and the visual system and the conveying drive source are electrically connected to the control module. The control module receives the recorded information of the visual system and controls the start and stop of the conveying drive source accordingly.

[0057] like Figure 2 As shown, in order to improve the cutting smoothness and reliability of the packing rope 103, the automatic cotton bale opening and feeding equipment also includes a centering mechanism 9, which includes two centering members arranged at intervals on both sides of the conveying line 1, each centering member includes a centering drive member 91 and a centering plate 92 connected to the output end of the centering drive member 91, and the centering drive member 91 can drive the centering plate 92 to move in a direction perpendicular to the conveying direction of the conveying line 1. When the cotton bale 100 to be opened moves between the two centering members, the centering drive member 91 drives the centering plate 92 to move, that is, the two centering plates 92 approach until the cotton bale 100 to be opened is clamped, which can not only fix the cotton bale 100 to be opened, but also adjust the position of the cotton bale 100 to be opened in the second direction to a preset fixed position. The second direction is perpendicular to the conveying direction of the conveying line 1, so that the cotton bale 100 to be opened can be directly below the belt cutting mechanism 2, that is, the belt cutting mechanism 2 can smoothly cut the packing rope 103 when it moves according to the preset trajectory. The centering drive member 91 may be, but is not limited to, a cylinder.

[0058] After the packing rope 103 is cut, the conveyor line 1 continues to convey the cotton bale 100 to be opened. The outlet end of the conveyor line 1 is provided with a clamping mechanism 3, which receives the cotton bale 100 to be opened. The side of the clamping mechanism 3 away from the outlet end of the conveyor line 1 is also provided with a cotton bale receiving mechanism 5, and an unpacking mechanism 4 is provided above the clamping mechanism 3. The cotton bale 100 to be opened is clamped by the clamping mechanism 3, and the outer coat 101 of the cotton bale 100 to be opened is cut by the unpacking mechanism 4, and then the clamping mechanism 3 is turned over to pour the cotton bale in the broken outer coat 101 into the cotton bale receiving mechanism 5, so as to separate the outer coat 101 from the cotton bale.

[0059] Specifically, the clamping mechanism 3 is located between the output end of the conveyor line 1 and the receiving end of the cotton bale receiving mechanism 5. The clamping mechanism 3 includes a mounting frame 31, an outer garment fixing component 32 and a clamping component 33 rotatably arranged on the mounting frame 31. The rotation axis of the clamping component 33 is perpendicular to the conveying direction of the conveyor line 1. The clamping component 33 has a material receiving position and a material releasing position relative to the mounting frame 31. When the clamping component 33 is located at the material receiving position, it is opposite to the output end of the conveyor line 1 and is used to receive the cotton bale 100 to be opened output from the output end of the conveyor line 1. The clamping component 33 can clamp or loosen the cotton bale 100 to be opened. The outer garment fixing component 32 is arranged on the clamping component 33 and is used to fix or loosen the outer garment 101 of the cotton bale 100 to be opened located on the clamping component 33. Under the transportation of the conveyor line 1, the cotton bale 100 to be opened automatically enters the clamping mechanism 3, the clamping component 33 clamps the cotton bale to be opened, and at the same time fixes the outer garment 101 through the outer garment fixing component 32, so that the unpacking mechanism 4 can cut the outer garment 101 of the cotton bale 100 to be opened, thereby improving the cutting and separation stability and efficiency; then the clamping mechanism 3 is turned over, and the cotton bale automatically falls under the action of gravity, and the outer garment 101 is still fixed in the clamping mechanism 3 under the fixing action of the outer garment fixing component 32, so that the cotton bale and the outer garment 101 are separated smoothly.

[0060] More specifically, if Figures 5 to 10 As shown, the clamping assembly 33 includes two hinged clamping back plates 331, and each clamping back plate 331 is slidably connected to a clamping side plate 332 perpendicular to the clamping back plate 331 along the width direction of the clamping back plate 331. The two clamping side plates 332 are respectively located on the opposite sides of the two clamping back plates 331 and can approach or move away from each other; a clamping space is formed between the two clamping back plates 331 and the two clamping side plates 332. When the clamping assembly 33 is located at the material receiving position, the clamping space is directly opposite to the output end of the conveyor line 1, and is used to receive the cotton bale 100 to be opened. Among them, each clamping side plate 332 is vertically connected to the corresponding clamping back plate 331, which conforms to the shape of the cotton bale 100 to be opened. Of course, in other embodiments, each clamping side plate 332 and the corresponding clamping back plate 331 can also be at other angles, such as an acute angle or an obtuse angle. Since the two clamping back plates 331 are hinged, when the two clamping back plates 331 rotate relative to each other, the opening between the two clamping side plates 332 is driven to become larger or smaller, that is, the opening of the clamping space becomes larger or smaller. When it becomes larger, it is convenient to receive the cotton bale 100 to be opened, and after receiving it, it becomes smaller to facilitate clamping the cotton bale 100 to be opened. In addition, the two clamping side plates 332 can slide relative to their corresponding clamping back plates 331, respectively, so that the size of the clamping space can be adjusted to accommodate cotton bales 100 to be opened of different sizes, and sufficient clamping force can be provided to clamp the cotton bale 100 to be opened, thereby ensuring the stability of the cotton bale 100 to be opened in the clamping mechanism 3.

[0061] In the present embodiment, an opening and closing driving member 333 is also provided on the mounting frame 31, and the opening and closing driving member 333 drives the two clamping back plates 331 to rotate relative to each other, thereby realizing the automatic opening and closing of the clamping space and the adjustable opening and closing angle. Specifically, the opening and closing driving member 333 includes two telescopic oil cylinders, one end of which is hinged to the mounting frame 31, and the other end is hinged to a clamping back plate 331. Through the extension and retraction of the telescopic oil cylinder, the two clamping back plates 331 are driven to rotate, thereby realizing the opening and closing of the clamping space. The telescopic oil cylinder has a simple structure, is easy to assemble, and has a low cost. Of course, in other embodiments, the opening and closing driving member 333 can also be other structures, such as a driving motor, which drives the clamping back plate 331 to rotate through gear transmission, etc., which is specifically set according to actual needs.

[0062] It is understandable that at least one adjusting drive member 334 is provided on the side of each clamping back plate 331 away from the clamping space, and the adjusting drive member 334 is driven and connected to the clamping side plate 332 to drive the clamping side plate 332 to move relative to the clamping back plate 331, thereby realizing the size adjustment of the clamping space. For example, the adjusting drive member 334 is a cylinder. Preferably, the clamping back plate 331 and the clamping side plate 332 are slidably connected through a slider and a slide rail, for example, the slide rail is laid on the clamping back plate 331 and connected with the slide rail, and the clamping side plate 332 is fixed to the slider through an adapter plate, and when the adjusting drive member 334 drives the clamping side plate 332 to move, the clamping side plate 332 slides relative to the clamping back plate 331, so that the connection stability between the clamping side plate 332 and the clamping back plate 331 is better, and the movement is smoother.

[0063] It should be noted that one slide rail or multiple slide rails may be provided on each clamping back plate 331 , depending on actual needs.

[0064] Preferably, a guide plate 337 and a baffle 339 are respectively provided at the opposite ends of each clamping back plate 331. When the clamping mechanism 3 is located at the material receiving position, the guide plate 337 is opposite to the exit end of the conveyor line 1. The guide plate 337 is preferably an inclined plate, that is, the guide plate 337 and the clamping back plate 331 are arranged at an angle. When the clamping mechanism 3 is located at the material receiving position, the end of the guide plate 337 away from the clamping back plate 331 is tilted downward so as to smoothly receive the cotton bale 100 to be opened output by the conveyor line 1; the cotton bale 100 to be opened enters the clamping space from the guide plate 337 under the conveyance of the conveyor line 1 until it abuts against the baffle 339. The baffle 339 can prevent the cotton bale 100 to be opened from falling from the clamping space, thereby ensuring the position stability and accuracy of the cotton bale 100 to be opened in the clamping space.

[0065] More preferably, a guide roller 338 is rotatably provided in each guide plate 337, so that the cotton bale 100 to be opened rolls on the guide roller 338 after reaching the guide plate 337, and can smoothly enter the clamping space to avoid jamming, etc. For example, a through hole is provided in each guide plate 337, and a guide roller 338 is rotatably installed in the through hole, and the guide roller 338 protrudes from the upper surface of the guide plate 337 to contact the cotton bale 100 to be opened.

[0066] The retaining hook 336 is used to hold the cotton bale 100 to be opened, so that the retaining hook 336 can be used to hold the cotton bale 100 to be opened.

[0067] Further, after the cotton bale 100 to be opened enters the clamping space, the clamping back plate 331 and the clamping side plate 332 movably clamp the cotton bale 100 to be opened, and then the outer garment fixing component 32 fixes the outer garment 101. Specifically, Figures 5 to 11 As shown, the outer garment fixing assembly 32 includes a plurality of cotton-wrapped needle members, at least one cotton-wrapped needle member is arranged on each clamping back plate 331 and / or each clamping side plate 332, and the cotton-wrapped needle member includes a mounting block 321, a driving plate 322, a needle driving member 323 and a plurality of needles 324. The mounting block 321 is arranged on the clamping back plate 331 or the clamping side plate 332, and a plurality of guide holes are opened on the mounting block 321. The plurality of needles 324 are arranged in parallel on the driving plate 322 at intervals, and one by one movably penetrates a guide hole. The needle driving member 323 is fixed on the mounting block 321 and drives the connected driving plate 322. The needle driving member 323 can drive the driving plate 322 to move back and forth, so as to drive the needles 324 to move back and forth along the guide holes, so that the needles 324 extend into the clamping space to pierce the outer garment 101 or withdraw from the outer garment 101. The needle driving member 323 drives the needle 324 to extend and retract in the guide hole, and the needle 324 can be inserted into the outer garment 101 or pulled out from the outer garment 101 as required. Since the outer garment 101 is generally made of a plastic mesh, which has strong air permeability and good extensibility, the outer garment 101 can be locked poorly by using a common clamping structure or a vacuum suction cup structure. The outer garment 101 can be better pulled by the needle 324 inserted into the outer garment 101, and the structure is simple.

[0068] Preferably, each needle 324 is at an angle to the length or width of the cotton bale 100 to be opened, that is, the needle 324 is inserted obliquely into the outer garment 101, which has a better locking effect on the outer garment 101, for example, inserted at an angle of 30 degrees. The needle 324 is, for example, a 4 mm stainless steel needle.

[0069] Exemplarily, each clamping back plate 331 and each clamping side plate 332 are provided with a plurality of mounting holes, for example, two or three, and each mounting hole corresponds to a mounting block 321, so that three sides of the outer garment 101 can be locked at the same time.

[0070] In this embodiment, a material sensor is provided on the conveyor line 1 or the clamping mechanism 3. The material sensor is used to detect whether the cotton bale 100 to be opened enters the clamping space. The material sensor, the opening and closing drive 333, the adjusting drive 334 and the needle drive 323 are all electrically connected to the control module. By setting the material sensor detection signal to be fed back to the control module, the control module controls the start and stop of the opening and closing drive 333, the adjusting drive 334 and the needle drive 323 according to the detection signal. The automation degree is high, which is conducive to improving work efficiency. After the material sensor detects that the cotton bale 100 to be opened enters the clamping space, the opening and closing drive 333 and the adjusting drive 334 are started, driving the clamping back plate 331 and the clamping side plate 332 to clamp the cotton bale 100 to be opened, and then the needle drive 323 is started to drive the needle 324 to pierce the outer garment 101.

[0071] After the cotton bale 100 to be opened is fixed by the clamping assembly 33 and the outer garment fixing assembly 32, the unpacking mechanism 4 is started to cut the outer garment 101. Specifically, the unpacking mechanism 4 includes an unpacking bracket 41, an unpacking movable module 42 and an unpacking tool 43. The unpacking movable module 42 is arranged on the unpacking bracket 41 and is located above the clamping mechanism 3. The unpacking tool 43 is arranged at the driving end of the unpacking movable module 42. The unpacking movable module 42 can drive the unpacking tool 43 to move in the X, Y and Z directions to drive the unpacking tool 43 to contact or move away from the outer garment 101 of the cotton bale 100 to be opened in the clamping assembly 33. The unpacking tool 43 can cut off the outer garment 101 of the cotton bale 100 to be opened. In the actual working process, the clamping assembly 33 also has an unpacking position relative to the mounting frame 31. After the clamping assembly 33 and the outer garment fixing assembly 32 fix the cotton bale 100 to be opened, the clamping assembly 33 flips a certain angle to the unpacking position, so that the cotton bale 100 to be opened is in an inclined state relative to the horizontal plane, so that the unpacking mechanism 4 can cut the two end surfaces of the cotton bale 100 to be opened. After the clamping mechanism 3 flips to a certain angle, the unpacking moving module 42 drives the unpacking tool 43 to move along the Z direction to approach the cotton bale 100 to be opened, until the unpacking tool 43 contacts the cotton bale 100 to be opened, and then the unpacking moving module 42 drives the unpacking tool 43 to move along the X and Y directions, so that the unpacking tool 43 cuts the outer garment 101 along the X and Y directions.

[0072] like Figure 5 As shown, in this embodiment, the unpacking moving module 42 includes a third linear moving module, a fourth linear moving module and a fifth linear moving module. The third linear moving module is arranged on the unpacking bracket 41, and is driven to connect with the fourth linear moving module to drive the fourth linear moving module to move along the X direction. The fourth linear moving module is driven to connect with the fifth linear moving module to drive the fifth linear moving module to move along the Z direction. The fifth linear moving module is driven to connect with the unpacking tool 43 to drive the unpacking tool 43 to move along the Y direction, wherein the X direction is the length direction of the cotton bale 100 to be opened, for example, when the cotton bale 100 to be opened is located on the conveying line 1, its length direction is consistent with the conveying direction, the Y direction is the width direction of the cotton bale 100 to be opened, and the Z direction is the thickness direction of the cotton bale 100 to be opened. After the clamping mechanism 3 is flipped to a certain angle, the fifth linear moving module drives the unpacking tool 43 to move down close to the cotton bale 100 to be opened, until the unpacking tool 43 contacts the outer garment 101, and the third linear moving module and the fourth linear moving module work successively to drive the unpacking tool 43 to slide on the outer garment 101 to cut the outer garment 101. Through the driving of the unpacking moving module 42, for example, the outer garment 101 is cut at the two end surfaces and the upper surface of the cotton bale 100 to be opened, where the upper surface refers to the side away from the clamping back plate 331. Among them, the third linear moving module, the fourth linear moving module and the fifth linear moving module can be selected but not limited to a screw type moving module or a synchronous belt type moving module.

[0073] Preferably, two fourth linear motion modules and two fifth linear motion modules are respectively provided, and two unpacking cutters 43 are provided, so as to simultaneously split the two end surfaces of the cotton bale 100 to be unpacked, thereby improving work efficiency.

[0074] Among them, the unpacking tool 43 is a dust-free mini saw. Of course, in other embodiments, the unpacking tool 43 can also be other types of tools, for example, including a second drive motor and a second blade driven by the second drive motor. The second drive motor drives the second blade to rotate, so as to quickly cut off the outerwear 101 it contacts.

[0075] After the outer garment 101 is cut, the clamping mechanism 3 is continuously rotated so that the clamping assembly 33 is located at the discharge position relative to the mounting frame 31 to dump the cotton bale, for example, the clamping assembly 33 is flipped 140 degrees from the material receiving position to the material discharging position. Specifically, the clamping mechanism 3 also includes a rotating drive member 34, and the clamping assembly 33 also includes a support frame 335. The support frame 335 is rotatably mounted on the mounting frame 31 through a rotating shaft and a rotating bearing, and the clamping back plate 331 is mounted on the support frame 335. The rotating drive member 34 drives the connecting shaft to drive the rotating shaft to rotate, that is, drives the support frame 335 to rotate, thereby driving the entire clamping assembly 33 to rotate, and realizing the switching between the material receiving position, the unpacking position and the material discharging position of the clamping assembly 33. Among them, the rotating drive member 34 can be selected but not limited to a rotating motor.

[0076] After the clamping assembly 33 is turned over to the discharge position, the two clamping back plates 331 are opened and / or the two clamping side plates 332 move in opposite directions to loosen the cotton bale 100 to be opened, and the cotton material 102 in the outer garment 101 can fall to the receiving end of the cotton bale receiving mechanism 5 under the action of gravity. Exemplarily, the cotton bale receiving mechanism 5 includes a cotton bale conveyor belt, and the receiving end of the cotton bale conveyor belt is located directly below the discharge position. After the cotton material 102 falls on the cotton bale conveyor belt, the cotton bale conveyor belt conveys the cotton material 102 to the cotton bale collection frame or the next process, so as to realize automatic feeding of the cotton bale. The cotton bale conveyor belt is, for example, an electric transmission belt.

[0077] Preferably, the cotton bale conveyor belt uses 8mm bent stainless steel as a support plate, which is sufficient to withstand the impact of the cotton bale falling process.

[0078] The material is connected by the clamping mechanism 3, and the outer garment 101 is opened on the clamping mechanism 3. The cotton material 102 and the outer garment 101 are also separated by the clamping mechanism 3, so that the working process of the automatic cotton bale opening and feeding equipment is smooth and efficient, and the structure is compact and the space utilization rate is high.

[0079] Furthermore, if Figure 1 As shown, the automatic cotton bale opening and feeding equipment also includes a clamping mechanism displacement module 10, which is arranged between the conveying line 1 and the cotton bale receiving mechanism 5, and a mounting frame 31 is arranged at the driving end of the clamping mechanism displacement module 10. The clamping mechanism displacement module 10 is used to drive the clamping mechanism 3 to move in a direction perpendicular to the conveying direction of the conveying line 1. When the cotton bale falls into the cotton bale receiving mechanism 5, the clamping mechanism displacement module 10 drives the clamping mechanism 3 to move to enter the next process, such as the subsequent recycling of outerwear 101. Specifically, the clamping mechanism displacement module 10 includes a slide and a driving source. The mounting frame 31 is slidably connected to the slide through a slide seat to improve the smoothness of movement. The driving source drives the mounting frame 31 to drive the mounting frame 31 to slide on the slide. For example, the driving source is a screw drive structure, a cylinder or a linear moving module.

[0080] After the cotton bale falls from the outer garment 101, some loose cotton will remain in the outer garment 101. In order to automatically collect the loose cotton, the cotton bale automatic opening and feeding device further includes a loose cotton recovery mechanism 7, which is arranged on one side of the clamping mechanism displacement module 10 and is located on the same side as the cotton bale receiving mechanism 5. When the clamping assembly 33 is located at the discharge position, with the driving of the clamping mechanism displacement module 10, the clamping assembly 33 can face the receiving end of the cotton bale receiving mechanism 5 or the receiving end of the loose cotton recovery mechanism 7, and the receiving end of the loose cotton recovery mechanism 7 is used to receive the loose cotton scattered in the outer garment 101. With the movement of the clamping mechanism 3, the clamping space can face the receiving end of the loose cotton recovery mechanism 7, and then through the movement of the clamping back plate 331 and the clamping side plate 332, the loose cotton in the outer garment 101 is shaken off and falls into the loose cotton recovery mechanism 7, thereby realizing the automatic recovery of the loose cotton.

[0081] Exemplarily, the loose cotton recovery mechanism 7 includes a loose cotton conveyor belt 71 and a loose cotton collecting frame 72. The loose cotton conveyor belt 71 is arranged side by side with the cotton bale conveyor belt. The loose cotton collecting frame 72 is located at the output end of the loose cotton conveyor belt 71. The loose cotton falls on the loose cotton conveyor belt 71 and is transported to the loose cotton collecting frame 72 by the loose cotton conveyor belt 71.

[0082] Specifically, the automatic cotton bale opening and feeding device further includes a coat recovery mechanism 8, which is arranged on one side of the clamping mechanism displacement module 10 and is located on the same side as the cotton bale receiving mechanism 5. When the clamping assembly 33 is located at the discharge position, with the driving of the clamping mechanism displacement module 10, the clamping assembly 33 can face the receiving end of the cotton bale receiving mechanism 5 or the receiving end of the coat recovery mechanism 8, and the receiving end of the coat recovery mechanism 8 is used to receive the coat 101. With the movement of the clamping mechanism 3, the clamping space can face the receiving end of the coat recovery mechanism 8, and then the coat 101 is released by the retraction of the needle 324, so that the coat 101 falls freely into the coat recovery mechanism 8, and the automatic recovery of the coat 101 is realized.

[0083] Exemplarily, the outer garment recovery mechanism 8 includes an outer garment conveyor belt 81 and an outer garment collection frame 82. The outer garment conveyor belt 81 is arranged side by side with the cotton bale conveyor belt. The outer garment collection frame 82 is located at the output end of the outer garment conveyor belt 81. The outer garment 101 falls on the outer garment conveyor belt 81 and is transported to the outer garment collection frame 82 by the outer garment conveyor belt 81.

[0084] The automatic cotton bale opening and feeding equipment provided in this embodiment realizes automatic feeding and conveying of the cotton bale 100 to be opened, automatic belt cutting, automatic separation of the cotton bale and the outer garment 101, and automatic recovery, which can significantly improve the work efficiency and product quality of the pretreatment of refined cotton raw materials, reduce the labor intensity of workers, and improve the on-site working environment to realize unmanned production. The entire feeding process is unmanned, efficient and smooth, which is conducive to promoting the pretreatment of raw materials to a high-level intelligent production line, that is, it is conducive to promoting industrial upgrading.
