DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 10 As shown, the present invention provides an automatic fiber cotton cutting machine, comprising an automatic fiber cotton feeding device 20 and an automatic fiber cotton cutting device 21 which are sequentially arranged on a machine frame 1 and used in conjunction with each other, respectively completing automatic continuous feeding and automatic continuous cutting operations, and in the form of driving the fiber cotton 19 to be cut by feeding, ensuring the continuity of the movement of the fiber cotton 19 during the feeding and cutting processes, thereby avoiding the problem that insufficient continuity leads to the inability to achieve the technical purpose of continuous cutting based on continuous feeding;

[0037] Among them, the fiber cotton automatic cutting device 21 is mainly used in the cutting process of fiber cotton 19. Of course, its working principle can also be applied to other similar fields, as long as the automatic blanking and feeding of the corresponding materials can be completed. The fiber cotton automatic cutting device 21 includes a cutting base 22, a cutting knife 30 and a cutting reciprocating drive mechanism 24. The cutting base 22 is the main structure, and its main function is to provide a space for placing the material to be cut and to form a feeding and cutting work with the feeding station of the feeding device. Among them, a cutting slide 25 with a cross-sectional shape identical to that of the fiber cotton 19 is provided on the cutting base 22. For example, the cutting slide 25 is set as a circumferential closed structure, and the cutting base 22 is also provided with a number of cutting gaps 23 for the cutting knife 30 to cut back and forth. The cutting gaps 23 are perpendicular to the cutting slide 25, and the cutting gaps 23 are smaller than the diameter of a single fiber cotton 19. The movable end of the cutting reciprocating drive mechanism 24 is connected to the cutting knife 30. The cutting reciprocating drive mechanism 24 is a prior art, as long as it can realize reciprocating motion, for example, the cutting reciprocating drive mechanism 24 includes a connected lifting part and a tool holder, a sliding rod is provided on the tool holder, and a scale is provided on the sliding rod, and the cutting knife 30 is slidably and locked on the sliding rod. Furthermore, in the present invention, a support plate is provided on the cutting base 22, a guide hole is provided on the support plate, and a guide column matching the guide hole is provided on the tool holder. Furthermore, in the present invention, the lifting part includes a connected rotating motor 8, an eccentric wheel and an eccentric rod, and the eccentric rod is hinged to the tool holder;

[0038] The automatic blanking and feeding device 20 for fiber cotton is mainly used in the cutting process of fiber cotton 19. Of course, its working principle can also be applied to other similar fields, as long as it can complete the automatic blanking and feeding of corresponding materials. The blanking and feeding device includes a feeding base 2, a feeding plate 3 and a feeding reciprocating drive mechanism. The feeding base 2 is the main structure, and its main function is to provide a space for placing the material to be pushed, and to form a feeding and cutting work coordination with the cutting station of the cutting device; wherein, a feeding slide 4 is provided on the feeding base 2, and the feeding slide 4 is a U-shaped structure, and the opening of the U-shaped structure faces upward to receive the automatically falling fiber cotton 19. The side of the U-shaped structure, that is, the arm side, is provided with a feeding channel 5 for the sliding of the feeding plate 3 along the feeding direction. The feeding channel 5 is connected to the feeding slide 4. The feeding end of the feeding plate 3 with a blade-shaped structure passes through the feeding channel 5 radially into the feeding slide 4, that is, the feeding end (the other end) of the feeding plate 3 is perpendicular to the feeding direction. Of course, the specific way of entering the feeding slide 4 needs to be improved accordingly according to the specific structure of the feeding plate 3. For example, if the feeding plate 3 is a cylindrical rod, the cylindrical rod will be directly inserted along the axis of the feeding slide 4, and cannot be inserted radially. At that time, this kind of cylindrical rod structure, although it can achieve feeding The technical purpose of the material is to feed the material, but because it excessively increases the axial length of the device, making the volume of the device too large, it is not a preferred technical solution; at the same time, in order to prevent the feeding plate 3 from shifting other fiber cottons 19, the height of the material channel 5 is set to be smaller than the diameter of a single fiber cotton 19, and the height of the support arm of the U-shaped structure is not less than the diameter of a single fiber cotton 19, that is, the thickness of the material-dipping end of the feeding plate 3 will not be greater than the diameter of a single fiber cotton 19. Of course, in order to completely eliminate this risk, the opening position of the material channel 5 can also be arranged near the bottom wall of the U-shaped structure; the movable end of the feeding reciprocating drive mechanism is connected to one end of the feeding plate 3 Then, the feeding reciprocating drive mechanism is an existing technology, as long as it can realize reciprocating motion; at least one storage cavity 6 is provided above the feeding base 2, and the discharge port of each storage cavity 6 is connected to the corresponding feeding chute 4, and the material in the storage cavity 6 automatically falls from top to bottom into the feeding chute 4. The material in the storage cavity 6 can be stored in multiple ways, such as the implementation scheme in the following embodiment, or it can be stored in a single way, that is, the storage cavity 6 is used as a falling chute, and the material transported from the outside through a conveyor or other mechanism enters the storage cavity 6, and then falls from the storage cavity 6 to the feeding chute 4, as long as the functions of automatic dropping and automatic feeding can be realized;

[0039] The present invention adopts a method of providing a cutting gap 23 smaller than the diameter of the fiber cotton 19 on a cutting base 22 having a cutting slide 25 with the same cross-sectional shape as the fiber cotton 19, so that the cut fiber cotton 19 will not move upward with the cutting knife 30, avoiding the problem that the cross section of the fiber cotton 19 is warped and the edge of the cross section of the fiber cotton 19 is stuck in the cutting gap 23, thereby ensuring that the fiber cotton 19 can still maintain its original movement trajectory after being cut, thereby ensuring the smooth movement of the fiber cotton 19 in the cutting slide 25; at the same time, the discharge port of each storage cavity 6 is connected to the corresponding feeding slide 4, so that the fiber cotton 19 in the storage cavity 6 can It falls into the feeding chute 4 to achieve the technical purpose of automatic blanking; and a material selection channel 5 is opened on the side of the feeding chute 4, and the height of the material selection channel 5 is less than the diameter of a single fiber cotton 19, so that the feeding plate 3 can only push one automatically blanked fiber cotton 19 at a time, avoiding the problem of low feeding smoothness of the feeding plate 3; in summary, the present invention achieves the technical purpose of high automatic cutting efficiency of the fiber cotton 19 by ensuring the smooth movement of the fiber cotton 19 in the cutting chute 25 and the feeding chute 4 whose axes coincide and pass through, avoiding the problem in the prior art that only the cutting process has high fluency and the cutting process and the feeding process cannot achieve synchronous fluency.

[0040] As a specific implementation scheme, since a channel that is too long will cause excessive resistance to the movement of the fiber cotton 19, the feed end of the cutting chute 25 and the discharge end of the feeding chute 4 are arranged at intervals in the present invention to facilitate the smooth movement of the fiber cotton 19; at the same time, in order to avoid the fiber cotton 19 in the feeding process from being unable to enter the cutting process in a timely and accurate manner, the spacing between the feed end of the cutting chute 25 and the discharge end of the feeding chute 4 is set to no more than 1 cm in the present invention, so as to reduce the problem of easy misalignment of the axis of the end of the fiber cotton 19 due to excessive suspension length, thereby ensuring the accuracy of the transportation of the fiber cotton 19.

[0041] As a specific implementation scheme, when the front end surface of the fiber cotton 19 in the feeding process cannot abut against the rear end surface of the fiber cotton 19 in the cutting process, that is, the rear end surface of the fiber cotton 19 is deformed, in order to ensure that the fiber cotton 19 in the feeding process can smoothly enter the cutting process, a pushing mechanism (not shown) is provided on the side of the connecting area between the feeding end of the cutting slide 25 and the discharging end of the feeding slide 4 in the present invention. The pushing mechanism includes a connected pushing cylinder and a pushing plate. The moving direction of the pushing plate is perpendicular to the radial side of the fiber cotton 19. The pushing plate is in a C-shaped structure. The opening size of the C-shaped structure is slightly larger than that of the fiber cotton 19. The diameter of the fiber cotton 19, preferably, the C-shaped structure can also use a manipulator with a clamping function in the existing technology to complete the active clamping of the fiber cotton 19, which is the existing technology and will not be described in detail; the push plate pushes the fiber cotton 19 located in the cutting process to the side, so that it is separated from the cutting slide 25 or broken, completing the work of making way for the fiber cotton 19 in the feeding process, wherein the pushing cylinder can be determined by monitoring whether the falling of the fiber cotton 19 in the cutting process is continuous and whether the moving speed of the fiber cotton 19 is zero. When it is discontinuous or the moving speed is zero, and the feeding process works normally, the pushing cylinder starts.

[0042] As a specific embodiment, the cutting knife 30 of the present invention includes a knife base 26 and a cutting edge 27. The knife base 26 is slidably and locked on the slide rod. An inverted U-shaped mounting groove 28 is provided in the middle of the knife base 26. At this time, a radially locked fastening screw is provided on the knife base 26 for locking the cutting edge 27. The width of the mounting groove 28 is greater than the width of the cutting base 22. The cutting edge 27 is installed in the mounting groove 28. The depth of the mounting groove 28 is greater than the cutting depth of the cutting edge 27. Negative pressure suction ports 29 are relatively provided on the two side walls of the mounting groove 28. The negative pressure suction port 29 is located below the cutting edge 27. , the negative pressure dust suction port 29 is connected to the negative pressure source; the cutting gap 23 is in an inverted U shape, and the negative pressure dust suction port 29 is a vertical rectangle. The negative pressure dust suction port 29 covers the cutting gap 23 located on the two side walls of the cutting base 22; that is, the negative pressure dust suction port 29 is provided on the knife base 26, so that the debris generated during the cutting process can be cleaned up in time. On the one hand, it avoids the debris from gathering in the cutting gap 23, affecting the cutting depth and destroying the cutting effect. On the other hand, it avoids the debris from gathering in the cutting chute 25, affecting the coincidence of the axis of the fiber cotton 19 and the cutting chute 25, thereby ensuring the effective progress of the cutting work.

[0043] The negative pressure source in the present invention is a pulsed negative pressure source, that is, the negative pressure source is set to a pulsed negative pressure source, so that the negative pressure start-up time can match the cutting speed of the cutting knife 30, completing the work of quickly absorbing debris during cutting, and avoiding the problem of high energy consumption of the negative pressure source.

[0044] The following is an introduction to the automatic feeding device 20 for fiber cotton: as a specific implementation scheme of the feeding plate 3 with a blade-like structure, in view of the light weight of the fiber cotton 19, a plurality of fiber cottons 19 are placed in a vertical row in the storage chamber 6 of the present invention, and the initial position of the feeding plate 3 does not overlap with the falling area of ​​the fiber cotton 19 to be transported, thereby ensuring the smooth falling of the fiber cotton 19 to be transported; the ending position overlaps with the falling area of ​​the fiber cotton 19 to be transported, so that when the vertically arranged fiber cotton 19 continues to fall automatically, the fiber cotton 19 is fed. The material dial plate 3 can prevent other lightweight fiber cottons 19 except the currently pushed fiber cotton 19 from falling, avoiding the problem that the fiber cotton 19 falls to the pushing position in advance and the feeding dial plate 3 cannot return according to the feeding route, thereby ensuring the reciprocating feeding efficiency of the feeding dial plate 3; at the same time, it is also necessary to ensure that the material-facing surface of the feeding dial plate 3 protrudes from this overlapping area, so that the feeding dial plate 3 can separate the end of the fiber cotton 19 from the falling area of ​​the fiber cotton 19 to be transported, avoiding the problem that the fiber cotton 19 to be transported interferes with the previously fallen fiber cotton 19 after falling.

[0045] As a specific implementation scheme for placing the fiber cottons 19 in a vertical row, radial limiting portions 7 are arranged at intervals on both radial sides of each row of fiber cottons 19 in the present invention, that is, the radial limiting portions 7 on both sides form a vertical falling channel, and the length direction of the radial limiting portion 7 extends along the arrangement direction of the row structure to complete the radial limitation of each fiber cotton 19 arranged in the row, thereby avoiding the problem that the fiber cottons 19 cannot fall smoothly and automatically due to misalignment.

[0046] As an optimization scheme for the vertical row placement scheme, the radial limiting portion 7 at the middle position of each row of fiber cotton 19 in the present invention is a rotatable rod-shaped structure, and the rod-shaped structure is connected to the rotating motor 8, that is, by rotating the radial limiting portion 7 in the middle, the rotating radial limiting portion 7 drives each row of fiber cotton 19 to move downward. It should be noted here that: at least the radial limiting portion 7 in the middle position is in contact with the fiber cotton 19. At the same time, in order to prevent the fiber cotton 19 from moving toward its axial end, axial limiting portions are provided at both axial ends of each row of fiber cotton 19, and the axial limiting portions are vertical blocking plates.

[0047] As another optimization scheme for the vertical row placement scheme, a retractable pressing structure 9 is provided at the middle position of each row of fiber cotton 19 in the present invention, and the retractable end 10 of the pressing structure 9 is connected to the pressing plate 11, and the pressing plate 11 is set on the top of the fiber cotton 19 between the radial limiting parts 7, that is, as the fiber cotton 19 automatically falls, the retractable end 10 of the pressing structure 9 continues to fall, keeping the pressing plate 11 in contact with the topmost fiber cotton 19. It should be noted here that the retractable movement of the pressing structure 9 can be controlled by setting a pressure sensor on the surface in contact with the pressing plate 11 and the fiber cotton 19. When the pressure is less than a preset threshold, the pressing structure 9 It follows the movement, and the expansion and contraction amount each time is not less than the diameter of a single fiber cotton 19, preferably 10 to 20 times the diameter of the fiber cotton 19. When the pressure value is zero, the expansion and contraction end 10 of the pressing structure 9 returns to the contracted position. Of course, the technical purpose of the pressing plate 11 contacting the fiber cotton 19 in real time can also be achieved in other ways. For example, a sensing identification area is set on the uppermost fiber cotton 19, and an identification area capture device is set on the pressing plate 11. The sensing identification area is captured by the identification area capture device, and then the expansion and contraction end 10 of the pressing structure 9 is adjusted to ensure the relative position of the pressing plate 11 and the fiber cotton 19. This control method is an existing technology and will not be described in detail.

[0048] As a specific implementation scheme, the storage chamber 6 in the present invention is detachably connected to the feeding slide 4, that is, the storage chamber 6 can be installed on the feeding slide 4 later. On the one hand, the height of the device can be reduced to facilitate transportation and installation. On the other hand, multiple storage chambers 6 can be equipped, and each storage chamber 6 is pre-installed with row-shaped fiber cotton 19. When a storage chamber 6 is empty, it can be quickly disassembled and replaced with another storage chamber 6 through the quick-release connection structure in the prior art. As an implementation scheme of the quick-release connection structure, the storage chamber 6 and the feeding slide 4 are respectively provided with a plug-in part and a slot to form a quick-release connection structure. The discharge port of the storage chamber 6 is connected to the opening of the U-shaped structure to complete continuous blanking.

[0049] As a specific implementation scheme, in order to avoid the problem that the feeding plate 3 moves out of position, resulting in the feeding plate 3 being unable to prevent other fiber cottons 19 from falling except for the currently pushed fiber cotton 19, a limit switch 12 is provided on the sliding path of the feeding plate 3 in the present invention, and the limit switch 12 is close to the discharge end of the feeding slide 4.

[0050] As a specific implementation scheme, in order to improve the anti-stuck performance of the device, a pressure sensor 13 is provided on the material-facing surface of the feed plate 3 in the present invention. When the detection pressure value detected by the pressure sensor 13 is lower than or greater than the pressure range threshold, the alarm issues an alarm that there is a feeding risk for the fiber cotton 19. That is, a pressure sensor 13 is provided on the material-facing surface of the feed plate 3, so that when the detection pressure value detected by the pressure sensor 13 is lower than or greater than the pressure range threshold, the alarm issues an alarm that there is a feeding risk for the fiber cotton 19. On the one hand, the problem of no material to push at the feeding push position is avoided, and on the other hand, the problem of the fiber cotton 19 being stuck at the feeding push position is avoided.

[0051] As a specific implementation scheme, the feeding reciprocating drive mechanism in the present invention includes a reciprocating motor 14 and a transmission belt 15 connected to each other, and the transmission belt 15 is fixedly connected to one end of the feeding paddle 3. The above-mentioned transmission connection method is only one of the existing technologies. Other transmission structures can also be used as long as the technical purpose of reciprocating motion can be achieved; further, in order to ensure the sliding stability of the feeding paddle 3 and reduce the vibration phenomenon during the movement of the feeding paddle 3, the middle part of the feeding paddle 3 is slidably connected to the slide rail 16, that is, through the guidance of the middle guide rail, the suspended length of the feeding paddle 3 is shortened, eliminating the vibration phenomenon during movement.

[0052] As a specific implementation scheme, in the present invention, the feeding base 2, the feeding plate 3 and the feeding reciprocating drive mechanism are all arranged on the same frame 1, and the frame 1 is provided with rollers 17 and adjustable feet 18 in parallel to realize the movable, lockable and adjustable balance height functions of the equipment.

The above examples are only intended to help understand the present invention and its core concept. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention.
