Description

Technical Field

[0001] This invention belongs to the technical field of fiber cotton production equipment, and in particular relates to an automatic fiber cotton feeding device. Background Technology

[0002] Fiber rods, commonly known as perfume cores, oil-storage cotton, or filter cotton cores, are fiber bundles formed by combining multiple fine, porous fiber threads. Fiber rods are mainly used for air purification with natural, slow release and in products requiring water absorption and filtration functions. They are suitable for daily consumer products (air fresheners, car perfume holders, etc.), electronic products (USB mini humidifiers, electronic atomizers, miniature robot vacuums, etc.), and medical products (laboratory pipettes, oxygen concentrators, humidification bottles, etc.).

[0003] Currently, fiber rod cutting mainly employs mechanical cutting, such as the shearing device for humidifier cotton rods described in application number 202020432886.8. This device addresses the shortcomings of existing technologies where cotton rod blanks are prone to shifting. It includes a worktable, a pusher block, and a blade holder. A top frame is fixed to the worktable, and a motor guide rail is fixed to the lower side of the top frame. A traveling motor is fitted to the lower side of the motor guide rail, and a vertically downward first linear motor is fixed to the lower side of the traveling motor. The pusher block is fixed to the lower end of the output shaft of the first linear motor. A platform is fixed to the worktable, and a vertically downward second linear motor is fixed to the lower side of the top frame. A connecting frame is fixed to the lower end of the output shaft of the second linear motor, and a blade holder is fixed to the lower side of the connecting frame. A cutting blade perpendicular to the motor guide rail is detachably fixed to the lower side of the blade holder. By pushing the cotton rod blank forward quantitatively with the pusher block, the cutting length is accurate. During cutting, a pressure strip applies pressure to fix the cut, ensuring a vertical and flat cut end.

[0004] Based on the aforementioned existing technology, the applicant, after research, found that the existing technology only made significant improvements to the fiber cotton cutting process to ensure cutting effect and efficiency, but did not make corresponding improvements to the fiber cotton feeding process. This resulted in poor continuity of the fiber cotton processing process and could not further improve cutting efficiency. Furthermore, after conducting a relevant search on the feeding process, it was found that an adjustable automatic feeding bar cutting machine with application number 201620670497.2 discloses that "the cutting machine body is equipped with a splash guard and a cutting groove, a lifting switch and a cooling fan are installed on the side, and a cutting blade, a lifting cylinder, a shaft core and a motor are installed inside the machine body. The shaft core is connected to the motor, and the upper end of the lifting cylinder is connected to the shaft core through a bearing." The automatic bar cutting machine features a feeding bracket located on one side of the machine body. A feeding clamp is mounted on the feeding bracket, and a tube slot is located on the feeding clamp. The tube slot leads to the upper end of the cutting blade slot of the cutting machine. A push rod is located at the end of the tube slot, and a cylinder is located at the end of the feeding bracket. This automatic feeding bar cutting machine allows for more stable bar cutting by pushing the feeding mechanism, making operation convenient and saving feeding time. However, the automatic feeding function of this automatic feeding bar cutting machine only continuously feeds a single piece of material once. After the single piece of material is fed, subsequent materials cannot be fed using the feeding mechanism; instead, materials must be manually placed on the feeding mechanism, and the continuous feeding of single pieces of material must be repeated. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing an automatic fiber cotton feeding device that achieves continuous feeding based on automatic feeding technology.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides an automatic fiber cotton feeding device, including a feeding base, a feeding baffle, and a feeding reciprocating drive mechanism. The feeding base has a feeding slide with a U-shaped structure. A feeding channel for the feeding baffle to slide along the feeding direction is provided on the support arm side of the U-shaped structure. The feeding channel is connected to the feeding slide, and the height of the feeding channel is less than the diameter of a single fiber cotton. The height of the support arm of the U-shaped structure is not less than the diameter of a single fiber cotton. The movable end of the feeding reciprocating drive mechanism is connected to one end of the feeding baffle, and the other end of the feeding baffle is perpendicular to the feeding direction. At least one storage cavity is provided above the feeding base, and the outlet of each storage cavity is connected to the corresponding feeding slide.

[0007] Preferably, several fiber cottons are arranged vertically in the storage cavity, and the initial position of the feeding plate does not overlap with the falling area of ​​the fiber cotton to be conveyed; the ending position overlaps with the falling area of ​​the fiber cotton to be conveyed, and the receiving surface of the feeding plate protrudes from this overlapping area.

[0008] Preferably, radial limiting portions are provided at intervals on both radial sides of each row of fiber cotton.

[0009] Preferably, the radial limiting part at the middle position of each row of fiber cotton is a rotatable rod-shaped structure, the rod-shaped structure is connected to a rotary motor, and each row of fiber cotton is provided with an axial limiting part at both axial ends.

[0010] Preferably, a retractable pressing structure is provided at the middle position of each row of fiber cotton, the retractable end of the pressing structure is connected to the pressing plate, and the pressing plate is placed on top of the fiber cotton located between the radial limiting parts.

[0011] Preferably, the storage chamber is detachably connected to the feeding slide, and the storage chamber and the feeding slide are respectively provided with a plug-in part and a slot, and the discharge port of the storage chamber is connected to the opening of the U-shaped structure.

[0012] Preferably, a limit switch is provided on the sliding path of the feeding plate, and the limit switch is close to the discharge end of the feeding slide.

[0013] Preferably, a pressure sensor is provided on the feeding surface of the feeding plate. When the pressure value detected by the pressure sensor is lower than or higher than the pressure range threshold, the alarm will sound an alarm indicating that there is a feeding risk to the fiber cotton.

[0014] Preferably, the feeding reciprocating drive mechanism includes a reciprocating motor and a transmission belt connected together, the transmission belt is fixedly connected to one end of the feeding baffle, and the middle part of the feeding baffle is slidably connected to the slide rail.

[0015] Preferably, the feeding base, the feeding baffle, and the feeding reciprocating drive mechanism are all mounted on the same frame, and the frame is provided with rollers and adjustable feet arranged in parallel.

[0016] The present invention achieves the following beneficial effects compared to the prior art:

[0017] First, in this invention, the outlet of each storage chamber is connected to the corresponding feeding slide, so that the fiber cotton in the storage chamber can fall into the feeding slide, achieving the technical purpose of automatic feeding; at the same time, a feeding channel is opened on the side of the feeding slide, and the height of the feeding channel is smaller than the diameter of a single fiber cotton, so that the feeding plate can only push one automatically falling fiber cotton at a time, avoiding the problem of low feeding smoothness of the feeding plate.

[0018] Secondly, in this invention, the method of ensuring that the termination position of the feeding plate overlaps with the falling area of ​​the fiber cotton to be conveyed is adopted. This allows the feeding plate to prevent other fiber cotton, except for the currently pushed fiber cotton, from falling when the vertically arranged fiber cotton continues to fall automatically. This avoids the problem that the feeding plate cannot return along the feeding route because the fiber cotton falls to the pushing position in advance, thus ensuring the reciprocating feeding efficiency of the feeding plate.

[0019] Third, the present invention employs a pressure sensor on the feeding surface of the feeding plate, so that when the pressure value detected by the pressure sensor is lower or higher than the pressure range threshold, the alarm will sound an alarm indicating that there is a risk of feeding fiber cotton. On the one hand, this avoids the problem of no material to push at the feeding position, and on the other hand, it avoids the problem of fiber cotton getting stuck at the feeding position.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-7As shown, this invention provides an automatic feeding device for fiber cotton. This feeding device 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 feeding of the corresponding material. The feeding device includes a feeding base 2, a feeding baffle 3, and a feeding reciprocating drive mechanism. The feeding base 2 is the main structure, and its main function is to provide space for placing the material to be pushed and to cooperate with the cutting station of the cutting device to form a feeding and cutting operation. Among them, a feeding slide 4 is provided on the feeding base 2. The feeding slide 4 has a U-shaped structure, and the opening of the U-shaped structure faces upward to receive the material. The automatically falling fiber cotton 19 has a feeding channel 5 on the side of the U-shaped structure, i.e., on the side of the support arm, along the feeding direction, for the feeding baffle 3 to slide. The feeding channel 5 is connected to the feeding slide 4. The feeding end of the blade-shaped feeding baffle 3 passes radially through the feeding channel 5 and enters the interior of the feeding slide 4. That is, the feeding end (the other end) of the feeding baffle 3 is perpendicular to the feeding direction. Of course, the specific way of entering the feeding slide 4 needs to be modified according to the specific structure of the feeding baffle 3. For example, if the feeding baffle 3 is a cylindrical rod, the cylindrical rod will be directly inserted along the axis of the feeding slide 4, rather than passing through radially. In this case, the cylindrical rod structure... Although it achieves the technical objective of feeding, it excessively increases the axial length of the device, resulting in an overly large device size, and therefore is not considered a preferred technical solution. Furthermore, to prevent the feeding deflector 3 from dislodging other fiber cotton 19s, the height of the feeding channel 5 is set to be less than the diameter of a single fiber cotton 19, and the height of the U-shaped support arm is not less than the diameter of a single fiber cotton 19. That is, the thickness of the feeding end of the feeding deflector 3 will not exceed the diameter of a single fiber cotton 19. Of course, to completely eliminate this risk, the feeding channel 5 can also be positioned near the bottom wall of the U-shaped structure. The moving end of the feeding reciprocating drive mechanism and the feeding deflector 3... One end is connected, wherein the feeding reciprocating drive mechanism is 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 slide 4. The material in the storage cavity 6 automatically falls from top to bottom into the feeding slide 4. The material in the storage cavity 6 can store multiple materials, such as the implementation scheme in the following embodiment, or it can store a single material, that is, the storage cavity 6 is used as a falling slide. The material conveyed by the outside through the conveyor or other mechanism enters the storage cavity 6 and then falls from the storage cavity 6 into the feeding slide 4. As long as the functions of automatic material dropping and automatic material feeding can be realized, it is acceptable.

[0032] In summary, this invention connects the outlet of each storage chamber 6 to the corresponding feeding slide 4, allowing the fiber cotton 19 in the storage chamber 6 to fall into the feeding slide 4, thus achieving the technical objective of automatic material feeding. At the same time, by providing a feeding channel 5 on the side of the feeding slide 4, and by setting the height of the feeding channel 5 to be less than the diameter of a single fiber cotton 19, the feeding deflector 3 can only push one automatically feeding fiber cotton 19 at a time, avoiding the problem of low feeding smoothness of the feeding deflector 3.

[0033] As a specific embodiment of the feed baffle 3 with a blade-like structure, considering the lightweight nature of the fiber cotton 19, in this invention, several fiber cotton 19s are placed vertically in the storage cavity 6. The initial position of the feed baffle 3 does not overlap with the falling area of ​​the fiber cotton 19 to be conveyed, ensuring the smooth falling of the fiber cotton 19. The termination position overlaps with the falling area of ​​the fiber cotton 19 to be conveyed, so that when the vertically arranged fiber cotton 19 continues to fall automatically, the feed baffle 3 can prevent the fiber cotton 19 from falling except for the current falling area. Other lightweight fiber cotton 19s besides the pushed fiber cotton 19 do not fall, thus avoiding the problem that the fiber cotton 19 falls to the pushing position in advance, causing the feeding plate 3 to be unable to return along the feeding route, and ensuring the reciprocating feeding efficiency of the feeding plate 3. At the same time, it is also necessary to ensure that the receiving surface of the feeding plate 3 protrudes from this overlapping area, so that the feeding plate 3 separates the end of the fiber cotton 19 from the falling area of ​​the fiber cotton 19 to be conveyed, avoiding the problem of interference between the fiber cotton 19 to be conveyed and the previously falling fiber cotton 19 after it falls.

[0034] As a specific embodiment of the vertically arranged arrangement, each row of fiber cotton 19 in this invention is provided with radial limiting parts 7 at intervals on both radial sides. That is, the radial limiting parts 7 on both sides form a vertically downward falling channel. The length direction of the radial limiting parts 7 extends along the arrangement direction of the row structure to limit the radial direction of each fiber cotton 19 in the row arrangement, so as to avoid the problem that the fiber cotton 19 cannot fall smoothly and automatically due to misalignment.

[0035] As an optimized solution for the vertically arranged arrangement, the radial limiting part 7 at the middle position of each row of fiber cotton 19 in this invention is a rotatable rod-shaped structure. The rod-shaped structure is connected to the rotary motor 8. That is, by rotating the radial limiting part 7 in the middle, the rotating radial limiting part 7 drives each row of fiber cotton 19 to move downward. It should be noted that at least the radial limiting part 7 at 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 towards its axial end, axial limiting parts are also provided at both axial ends of each row of fiber cotton 19. The axial limiting parts are vertically shaped baffles.

[0036] As an optimized solution for the vertically arranged arrangement, this invention provides a retractable pressing structure 9 at the middle of each row of fiber cotton 19. The retractable end 10 of the pressing structure 9 is connected to a pressing plate 11, which rests on top of the fiber cotton 19 located between the radial limiting portions 7. As the fiber cotton 19 falls automatically, the retractable end 10 of the pressing structure 9 continuously descends, maintaining contact between the pressing plate 11 and the uppermost fiber cotton 19. It is important to note that the retractable movement of the pressing structure 9 can be controlled by installing a pressure sensor on the surface of the pressing plate 11 in contact with the fiber cotton 19. When the pressure is less than a preset threshold, the pressing structure 9... The extension and retraction amount is not less than the diameter of a single fiber 19, preferably 1 to 1.2 times the diameter of the fiber 19. When the pressure value is zero, the extension and retraction end 10 of the pressing structure 9 returns to the contracted position. Of course, the technical purpose of real-time contact between the pressing plate 11 and the fiber 19 can also be achieved in other ways, such as setting a sensing mark area on the uppermost fiber 19 and setting a mark area capturing device on the pressing plate 11. The sensing mark area is captured by the mark area capturing device, and then the extension and retraction end 10 of the pressing structure 9 is adjusted to ensure the relative position of the pressing plate 11 and the fiber 19. This control method is existing technology and will not be described in detail.

[0037] As a specific implementation scheme, the storage chamber 6 and the feeding slide 4 are detachably connected in this invention. That is, the storage chamber 6 can be installed on the feeding slide 4 later. On the one hand, this can reduce the height of the device and facilitate transportation and installation. On the other hand, multiple storage chambers 6 can be equipped. Each storage chamber 6 is pre-installed with row-shaped fiber cotton 19. When one 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 plug-in parts and slots 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 material feeding.

[0038] As a specific implementation scheme, in order to avoid the feeding plate 3 moving out of its proper place and causing the feeding plate 3 to fail to prevent other fiber cotton 19s besides the currently pushed fiber cotton 19 from falling, a limit switch 12 is provided on the sliding path of the feeding plate 3 in this invention, and the limit switch 12 is close to the discharge end of the feeding slide 4.

[0039] As a specific implementation scheme, in order to improve the anti-jamming performance of the device, a pressure sensor 13 is provided on the material receiving surface of the feeding deflector 3 in this invention. When the detection pressure value detected by the pressure sensor 13 is lower than or higher than the pressure range threshold, the alarm will issue a feeding risk alarm for the fiber cotton 19. That is, by providing a pressure sensor 13 on the material receiving surface of the feeding deflector 3, when the detection pressure value detected by the pressure sensor 13 is lower than or higher than the pressure range threshold, the alarm will issue a feeding risk alarm for the fiber cotton 19. On the one hand, this avoids the problem of no material to push at the feeding push position, and on the other hand, it avoids the problem of the fiber cotton 19 getting stuck at the feeding push position.

[0040] As a specific implementation scheme, the feeding reciprocating drive mechanism of the present invention includes a reciprocating motor 14 and a transmission belt 15 connected together. The transmission belt 15 is fixedly connected to one end of the feeding plate 3. The above-mentioned transmission connection method is only one of the prior art. Other transmission structures can also be used, as long as the technical purpose of reciprocating motion can be achieved. Furthermore, in order to ensure the sliding stability of the feeding plate 3 and reduce the vibration phenomenon during the movement of the feeding plate 3, the middle part of the feeding plate 3 is slidably connected to the slide rail 16. That is, by guiding the middle guide rail, the suspended length of the feeding plate 3 is shortened, eliminating the vibration phenomenon during movement.

[0041] As a specific implementation scheme, in this invention, the feeding base 2, the feeding baffle 3, and the feeding reciprocating drive mechanism are all mounted on the same frame 1. Rollers 17 and adjustable support legs 18 are arranged side by side on the frame 1 to realize the functions of movable, lockable, and adjustable balance height of the equipment.

[0042] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand this invention and its core ideas. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
