Description

Technical Field

[0001] This application relates to the field of cotton processing equipment technology, and more specifically to a sub-packing system adapted to a round cotton mold opening machine and a round cotton mold processing production line. Background Technology

[0002] With the increasing demands for production efficiency and automation in cotton processing technology, traditional manual bale opening can no longer meet the needs of modern production. In existing round cotton mold bale opening technology, the flipping and positioning of the round cotton mold often requires manual operation, or only rough mechanical positioning can be performed. This leads to inaccurate positioning of the round cotton mold before opening and seriously affects the bale opening efficiency. Utility Model Content

[0003] This application addresses the shortcomings of existing technologies by providing a sub-packing system and a round cotton mold processing line adapted to a round cotton mold opening machine. Through precise sensor identification and automatic positioning, this application can accurately flip the round cotton mold to a specific posture before supplying it to the opening machine, thereby effectively improving cutting accuracy and work efficiency, and significantly enhancing positioning precision and efficiency during the round cotton mold opening process. The specific technical solution adopted in this application is as follows.

[0014] Optionally, this application also provides a round cotton mold processing line, which includes a sub-packing system adapted to the round cotton mold opening machine as described above, and a round cotton mold opening and cutting device connected to the end of the conveyor line.

[0015] Beneficial effects

[0016] The sub-packing system and round cotton mold processing line adapted to a round cotton mold opening machine provided in this application utilize a sub-packing mechanism to receive and carry the round cotton molds supplied to the conveyor line. The round cotton molds are held in a preset position by their own weight. Simultaneously, a frictional torque is output along the outer circumference of the round cotton mold to drive it to rotate in place and position the positioning marks on the round cotton mold. When the round cotton mold is rotated to a preset angle, a flipping bracket is driven to push the round cotton mold to the conveyor line at a preset circumferential angle for subsequent equipment to cut and open the round cotton mold at a specific angle.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless defined as herein.

[0028] The meaning of "and / or" as used in this application includes situations where each exists alone or both exist simultaneously.

[0029] In this application, "inner" and "outer" refer to directions relative to the subcontracting support itself, with the direction pointing towards the center of the rotating roller inside the subcontracting support being "inner" and vice versa; rather than being a specific limitation on the device mechanism of this application.

[0030] The terms "left" and "right" as used in this application refer to the user's left side as the left and the user's right side as the right when the user is facing the forward direction of the round cotton mold in the subcontracting bracket, and are not a specific limitation on the device mechanism of this application.

[0031] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.

[0032] In this application, "up" and "down" refer to the direction from the support base of the subcontractor towards the top of the round cotton mold it supports when the user is facing the subcontractor, and vice versa, and are not a specific limitation on the device mechanism of this application.

[0033] Figure 1 According to this application, a sub-packing system adapted to a round cotton mold opening machine is provided, which is connected to the conveyor line 4 of the round cotton mold opening machine for conveying round cotton molds adjusted to a specific opening angle and posture to the round cotton mold opening and cutting equipment located at the end of the conveyor line 4 in the round cotton mold processing production line. The sub-packing system may specifically be configured to include:

[0034] The subcontracting mechanism 2 has several flipping units at its bottom that are parallel to the axis of the round cotton mold. These units are used to receive and carry the round cotton molds supplied to the conveyor line 4. The round cotton molds are held in a preset position at the bottom of the subcontracting mechanism 2 by their own weight. At the same time, the flipping units of the subcontracting mechanism 2 can also output frictional torque along the outer periphery of the round cotton mold to drive the round cotton mold to rotate in place at the preset position within the subcontracting mechanism 2. During this process, the positioning marks on the round cotton mold are detected and positioned.

[0035] A flipping support 26 is mounted on the sub-packing mechanism 2. A rotating shaft is located at the bottom of the sub-packing mechanism 2 near the conveyor line. This rotating shaft is rotatably connected to a positioning and flipping mechanism. Thus, when the round cotton mold is rotated to a preset, suitable angle for cutting and unpacking by the subsequent cutting equipment, the positioning and flipping mechanism supports the round cotton mold at that preset angle. Using the rotating shaft as the center, the rotating support pushes the round cotton mold, flipped to the preset angle, onto the conveyor line 4. This allows the round cotton mold to reach the cutting equipment in this special posture via the conveyor line connected to the sub-packing mechanism 2, where it is directly cut and unpacked at the preset angle.

[0036] In the aforementioned subcontracting system, this application, through the design of the support structure, enables the vertical components of the frictional torque acting on the outer periphery of the round cotton mold to cancel each other out during the in-situ rotation of the mold. This ensures that the horizontal component of the frictional torque acts on the outer periphery of the mold is in the same or opposite direction to the pushing direction of the positioning and flipping mechanism, allowing the round cotton mold to flip stably to a suitable angle for opening and cutting. This ensures that the round cotton molds can be stored and managed in an orderly manner before opening, effectively improving the automation level and processing efficiency of the round cotton mold opening process.

[0037] Specific reference Figure 2 Figure 3 as well as Figure 4As shown, the subcontracting system of this application mainly includes a storage section, a subcontracting section, and a conveying section arranged sequentially. The subcontracting section, formed by the subcontracting mechanism 2 and the mold-turning bracket 26, can specifically include:

[0038] The sub-packing bracket 24 has a downwardly concave arc at its top, which allows 20%-30% of the volume of the round cotton mold to be embedded in the concave arc of the sub-packing bracket 24 when the round cotton mold is stationary.

[0039] The flipping unit includes a plurality of rotating rollers 22 arranged parallel to each other on the top of the recessed area of ​​the turntable bracket 24, and the rotation axis of each rotating roller 22 is perpendicular to the pushing direction of the positioning flipping mechanism.

[0040] The sub-packaging mechanism 2 is also equipped with a detection unit, which is fixedly installed on the sub-packaging bracket 24 between two adjacent sets of rotating rollers 22. It is used to detect: the position of the round cotton mold, the position of the mold-flipping bracket 26, and the positioning marks attached to the round cotton mold package, so as to perform the following actions:

[0041] Based on the arrival status of the round cotton mold monitored by the device, the rotating roller 22 is triggered to rotate when the round cotton mold is received by the transfer bracket 24.

[0042] Based on the detection of the positioning marks on the round cotton mold, when the positioning marks are detected, the calculation of the flip angle corresponding to the cutting area of ​​the round cotton mold is triggered, and the sub-packing bracket 24 is triggered to push the round cotton mold onto the conveyor line 4 when the cutting area of ​​the round cotton mold is flipped to the preset posture angle.

[0043] After the subcontracting bracket 24 pushes the round cotton mold currently received by the subcontracting bracket onto the conveyor line, the entire subcontracting unit can be restored to its initial position to receive the next round cotton mold and trigger the repetition of the above steps. Thus, this application can achieve automated control of the entire round cotton mold subcontracting and positioning process through the cooperation of its various parts.

[0044] To further understand the features, technical means, objectives, and functions of this application, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0045] Example 1:

[0046] This embodiment provides a transfer mechanism and positioning method for a circular cotton mold opening machine, such as... Figure 1 As shown, the device includes a storage section 1, a sub-packaging mechanism 2, a support base 3, and a conveying section 4 arranged sequentially. The storage section 1 is used to hold the round cotton mold 7, the sub-packaging mechanism is mainly used to change the conveying direction of the round cotton mold 7, and the conveying section 4 is used to push the round cotton mold 7 forward to complete subsequent cutting, unpacking, and other operations.

[0047] The storage section 1 can use a chain drive mechanism, belt drive mechanism, or other types of transmission to receive round cotton molds and transfer them to the sub-packaging mechanism 2. The storage section 1 adopts a frame structure, which is simple in structure and easy to disassemble and transport. The storage section 1 can accommodate multiple round cotton molds 7, ensuring that a sufficient number of round cotton molds 7 are available for use, thereby reducing the working time of the round cotton mold handling vehicle and reducing production costs.

[0048] The subcontracting mechanism 2 is located at the output end of the storage section 1 and mainly includes a subcontracting bracket 24, a rectangular frame mold-flipping bracket 26, a rotating roller 22, etc. The subcontracting bracket 24 is used to support the rotating roller 22. The rotating roller 22 is driven by a hydraulic motor 23 and rotates through a chain drive, thereby driving the round cotton mold 7 that is above it to rotate.

[0049] To accommodate the shape of the round cotton mold, the tops of the support plates on both sides of the transfer bracket 24 can be set as downward-concave arcs. Multiple rotating rollers 22 are distributed across the support plates on both sides of the transfer bracket 24, forming an arc-shaped support surface. Each rotating roller 22 is driven by a gear through a hydraulic motor 23. The gears mesh with the corresponding chain drive structure, thereby driving the rollers to rotate. The rotating rollers 22 rub against the bottom of the round cotton mold 7, causing the round cotton mold to rotate accordingly.

[0050] The flipping support 26 is a rectangular frame structure. One end of the sub-packing support 24 is rotatably connected to the flipping support 26, and the other end has a pair of flipping templates 29, which are set on the upper side of the sub-packing support 24. An additional pair of flipping templates 29 can be optionally added in the middle of the flipping support 26 to prevent the round cotton mold 7 from getting stuck during the flipping process. A hydraulic cylinder, driven by a hydraulic motor, supports the bottom of the flipping support 26. The hydraulic cylinder pushes the flipping support upwards to support the round cotton mold and push it to the next level of the conveyor line. In the above structure, the hydraulic motor and hydraulic cylinder are powered by a hydraulic pump. During the flipping process, the flipping templates can support and push the round cotton mold upwards, causing the flipping templates to lift upwards. During this flipping process, the space between the flipping templates better adapts to the shape of the round cotton mold, allowing the round cotton mold to be stuck between the flipping templates by gravity. The pressure on the flipping templates increases the friction between them, thereby causing the round cotton mold to rotate at a fixed angle. The pointed structure of the flipping template can mimic the upward lifting motion of a human hand, providing stability for the flipping process of the round cotton mold.

[0051] An RFID reader 27 is installed on the side of the mold-flipping bracket 26 opposite to the flipping end. A pair of photoelectric through-beam switches 28 are installed on both sides of the sub-packing bracket 24. The photoelectric through-beam switches 28 are used to sense the position of the round cotton mold. The RFID reader 27 is used to identify the RFID tag 6 of the round cotton mold, thereby determining the appropriate cutting range of the round cotton mold 7. The identification by the RFID reader 27 can prevent the short material head from occurring during film cutting.

[0052] In this embodiment, four sets of rotating rollers 22 are provided. The first set of rotating rollers is located at the top of the end of the transfer bracket 24 away from the conveyor line. It is used to receive the round cotton mold pushed from the storage section into the transfer bracket 24, provide cushioning, and help the round cotton mold smoothly reach the bottom of the concave arc receiving surface of the transfer bracket 24. The second and third sets of rotating rollers are sequentially located at the bottom of the concave area in the transfer bracket 24. They are used to stably support the round cotton mold and drive it to flip until it reaches a suitable angle for opening and cutting. The fourth set of rotating rollers is located at the top of the other end of the transfer bracket 24 near the conveyor line. It is used to provide support and transmission for the flipping and output process of the round cotton mold.

[0053] To detect the position of the circular cotton mold and the attitude angle during the flipping process in the above process, this application preferably sets the detection unit to include:

[0054] Photoelectric photoelectric switches 28 are positioned opposite each other between the second and third sets of rotating rollers, and can be located on both sides of the transfer bracket 24. They are used to detect whether the round cotton mold has reached the bottom position of the recessed area of ​​the transfer bracket 24. When the photoelectric photoelectric switch detects the round cotton mold 7, the detection signal of the photoelectric photoelectric switch 28 is blocked by the round cotton mold. Thus, the change in the detection signal can trigger the hydraulic motor to start, thereby driving the rotating roller 22 to rotate to adjust the posture angle of the round cotton mold loaded on it.

[0055] An RFID reader 27 is positioned between the second set of rotating rollers and the first set of rotating rollers, and can be respectively installed at both ends of the connecting rod 21. The radiation direction of each RFID reader 27 is set towards the center of the recessed area of ​​the transfer bracket 24, and is used to detect the RFID tag 6 on the round cotton mold package as a positioning mark. When the RFID reader 27 senses the RFID tag 6 on the round cotton mold 7, the control system will stop the rotation of the hydraulic motor 23 within a preset interval. Since the total length of the packaging film is fixed and the position of the RFID tag 6 attached to the round cotton mold 7 is fixed, the diameter range of the round cotton mold 7 varies little. Therefore, the relative position of the material head inside the round cotton mold can be calculated according to the RFID detection position, so that the rotation time of the round cotton mold 7 to rotate the material head corresponding to the opening of the package to the top can be accurately calculated.

[0056] In the above structure, the sub-packing bracket 24 is disposed on one side of the conveyor line, and the output end of the sub-packing mechanism 2 is connected to the conveying section 4. The conveying section 4 is used to push the round cotton mold 7 forward onto the transmission roller of the conveying section, so as to transport the round cotton mold flipped to a specific angle to the subsequent cutting equipment to complete subsequent operations such as unpacking. In order to transport the round cotton mold flipped to a specific angle onto the conveyor line 4 in a smooth manner, the sub-packing bracket 24 of this application is also provided with a fixed inclined surface 5 connecting the outer side of its first set of rotating rollers and the conveyor line 4. The fixed inclined surface 5 is disposed in the frame structure of the conveying section 4 by the conveying bracket 31. The fixed inclined surface 5 provides a buffer for the round cotton mold, so that it can be transferred onto the conveyor line by the inclined surface near the side of the sub-packing section 7. In the conveying unit 4, the conveying rollers and rotating rollers 22 on the conveying line are set perpendicular to each other. This allows the flipped round cotton mold to be conveyed along its axial direction to the cutting equipment. This conveying direction is perpendicular to the conveying direction of the storage unit 1, effectively preventing the round cotton mold from further flipping circumferentially during the conveying process, which would make it impossible to accurately determine the cutting angle of the cutting equipment and affect the efficiency of cotton collection and subsequent processing after cutting. The conveying unit 1 specifically includes a conveying support 31, on which multiple conveying rollers 32 are sequentially installed. The axial direction of the conveying rollers 32 is perpendicular to the axis of the rotating rollers 22. During the rotation of the sub-packing mechanism, the cutting range of the round cotton mold is determined by identification and positioning. After rotating a certain angle, it is flipped to ensure that the cutting range of the flipped round cotton mold falls exactly on the corresponding cutting position. Each conveying roller 32 is driven by a conveying motor, which is connected to each conveying roller 32 through a chain drive mechanism.

[0057] In this embodiment, the conveying bracket 31 serves to support the conveying roller 32 and is configured as a frame structure. On the side of the conveying bracket 31 away from the sub-packing mechanism 2, opposite the sub-packing bracket 24, a concave baffle 33 is provided. The inner surface of the baffle 33 is arc-shaped to prevent the round cotton mold 7 from getting stuck when it flips over under the action of the flipping bracket 26. A conveying part photoelectric switch 34 is installed inside the baffle 33. The conveying part photoelectric switch 34 is used to detect the position of the round cotton mold 7. The detection signal of the round cotton mold arriving on the conveying line ensures its smooth passage through the conveying part 4, while simultaneously driving the sub-packing bracket 24 to return to its original position, continuing to wait for the detection signal of the photoelectric through-beam switch 28 for the next round cotton mold carried on the sub-packing mechanism 2. Thus, in response to the detection signal of the round cotton mold arriving on the conveying line by the photoelectric switch 34, the sub-packing bracket 24 is triggered to lower, restoring the flipping plate 29 to its initial position in the gap between the rotating rollers 22.

[0058] Example 2:

[0059] This embodiment provides a transfer positioning method for a circular cotton mold opening machine, which adopts the transfer mechanism described in Embodiment 1, and drives the transfer system to perform the in-situ flipping and transfer process of the circular cotton mold according to the following steps:

[0060] The round cotton mold is transported to the storage section 1 by a transport vehicle. A chain conveyor belt at the bottom of the storage section causes the round cotton mold to roll forward to the transfer mechanism 2. In the transfer mechanism 2, the round cotton mold is supported by a support surface composed of multiple arc-shaped rotating rollers. Due to gravity, the round cotton mold 7 is blocked between the photoelectric photoelectric switches 28 located on both sides of the transfer bracket. This allows the entire device to respond to the detection signals from the photoelectric photoelectric switches 28 regarding the round cotton mold carried on the transfer mechanism 2. When the round cotton mold reaches the bottom position of the recessed area of ​​the transfer bracket 24, it triggers the synchronous operation of each rotating roller 22. The surface of the rotating rollers is usually covered with rubber or polyurethane material to increase friction and prevent the cotton mold from slipping. When the RFID reader 27 reads the detection signal of the RFID tag 6 on the cotton mold during the rotation of the round cotton mold, it can trigger the calculation of the cutting area of ​​the round cotton mold, thereby continuing to drive each rotating roller 22 to rotate at the corresponding angle, rotating the cutting area to the top of the round cotton mold, and making the round cotton mold maintain the preset posture and transfer it to the conveyor belt through the flipping of the mold support, and finally transport it to the cutting equipment to directly cut the cutable area 72 on its top.

[0061] Therefore, this application can take advantage of the fixed length of the packaging film of the round cotton mold, the relatively fixed position of the label attached to it, and the small variation in the diameter range of the round cotton mold. By detecting the position of the positioning label angle, a relative position between the label and the internal material head can be calculated, thereby determining the rotation angle of the rotating roller relative to the round cotton mold. Based on the rotation speed of the rotating roller, the approximate time when it stops rotating can be determined, ensuring the posture angle of the material reaching the conveyor line and being sent to the cutting and unpacking equipment.

[0062] In the implementation process, considering that the RFID tag 6 of the round cotton mold 7 is stuck to one end, in order to ensure that each round cotton mold 7 can be detected, this application preferably installs a set of RFID readers 27 on the connecting rod 21 of the subcontracting mechanism 2. When the RFID reader 27 senses the RFID tag 6 of the round cotton mold 7, the rotation of the hydraulic motor 23 stops accordingly.

[0063] Since the total length of the packaging film is fixed and the RFID tag 6 of the round cotton mold 7 is attached at a fixed position, the diameter of the round cotton mold 7 varies within a small range. Therefore, the rotation time of the hydraulic motor 23 can be calculated based on the relative position of the RFID tag 6 and the internal material head. By controlling the stopping time of the roller rotation, the round cotton mold can be accurately adjusted to a position where the cutable position of the package head is at the top and transferred to the conveyor line, so that it can directly enter the cutting mechanism for opening and cutting.

[0064] After the hydraulic motor 23 stops rotating, the flipping bracket 26 is pushed by the hydraulic cylinder 25 to flip the round cotton mold 7 to the conveying section 4. At this time, the material head inside the packaging film will... Figure 6 The method maintains the material head of the round cotton mold in the upper part of the mold area. After transferring it to the conveyor line, the material head of the round cotton mold can be maintained near the above position, so that the round cotton mold can be conveyed to the subsequent cutting equipment in this posture for direct cutting.

[0065] During the flipping process, the flipping plate can automatically adjust the contact angle according to the shape of the round cotton mold. The contact material on the surface of the flipping plate has a buffer pad, which can match the outer contour of the round cotton mold and increase the friction.

[0066] In practice, the support base 3 of the aforementioned subcontracting mechanism 2 is horizontally positioned on the ground and fixed to the plane of the support base 3 with bolts. The subcontracting bracket 24 forms an arc-shaped support surface with multiple rotating rollers 22 via connecting rods 21. The rotating rollers 22 support the round cotton mold, with their surfaces in contact with the mold and driven to rotate by hydraulic motors. The four rotating rollers are arranged in an arc shape to better adapt to the shape of the round cotton mold and prevent it from rolling out directly from the storage section to the subcontracting section due to its large size and weight. A connecting rod 21 can be installed behind the label sensor facing the bottom roller. The connecting rod serves two purposes: first, to install and fix the label sensor; and second, to provide support by being placed horizontally between the flipping brackets. A large drop can generally be provided between the rollers before and after the connecting rod, and the connecting rod can be moved a certain distance from the circumference of the round cotton mold towards the conveyor line. This is because the connecting rod and the label sensor are fixed structures and do not participate in rotation. The position of the connecting rod can be set slightly lower than the contact surface between the rotating roller and the round cotton mold to avoid hindering the normal operation of the rotating roller.

[0067] Since the diameter of the round cotton mold is not fixed, this application generally does not specify the curvature and depth of the downward indentation of the sub-packing bracket in order to fix and hold the round cotton mold in place. However, it is generally required that the round cotton mold can be embedded in the sub-packing bracket in a static state where it is completely maintained by gravity, accounting for 20%-30% of its volume. At this point, the round cotton mold can be kept fixed and there should be no jamming or other issues during the flipping process.

[0068] The mold-flipping bracket 26 can be specifically configured to include: Figure 4 , Figure 5 The rectangular frame structure shown includes:

[0069] The main body of the support is symmetrically arranged on both sides of the sub-package support 24;

[0070] Hydraulic cylinders 25 are respectively supported under the support body on both sides of the sub-packing bracket 24, and are used to drive the support body to lift according to the detection signal that the round cotton mold is rotated to a preset posture angle;

[0071] The flip template 29 is set in pairs between the support body. During the rotation of the round cotton mold, the support body is lowered and accommodated in the gap between the first two sets of rotating rollers 22 and the last two sets of rotating rollers 22. When the support body is lifted, the common bearing end is supported under the round cotton mold that has reached the preset posture angle.

[0072] After the photoelectric switch 33 of the conveying unit senses the round cotton mold 7, the mold flipping bracket 26 is pushed back to its initial position by the hydraulic cylinder 25. At the same time, the motor of the conveying unit 4 starts, and the round cotton mold 4 begins to be conveyed forward to the cutting area (the specific cutter position is not shown in the figure). The conveying unit can transport the flipped and positioned round cotton mold to the subsequent processing stage, ensuring the smoothness and efficiency of the entire system operation.

[0073] The limit switch 210 located below the flip template 29 can reset each mechanism of the equipment after sensing the flip template 29, so that the storage section 1 is ready to enter the next stage of preparation work, in order to enter the next cycle.

[0074] To avoid interference from the mold-flipping bracket 26 during the in-situ rotation of the bottom circular cotton mold of the sub-packing mechanism 2, this application may also refer to... Figure 5 Preferably, the subcontractor 24 has the following features on its side wall:

[0075] The template mounting groove has a groove depth that is not less than the template thickness and does not exceed the radius of the rotating roller 22. It is used to accommodate the template 29 that extends inward in the template support 26 to support the round cotton mold.

[0076] The support rod, located at the bottom of the recessed area between the fourth set of rotating rollers and the third set of rotating rollers, is used to connect the two side walls of the transfer bracket 24 to provide support and prevent the bracket structure from deforming when bearing the round cotton mold.

[0077] An RFID mounting rod is positioned between the first set of rotating rollers and the second set of rotating rollers, and is positioned at a height higher than the top of the second set of rotating rollers, for fixing the detection angle of the RFID reader 27.

[0078] A rotating shaft mounting groove is provided below the first set of rotating rollers for mounting the rotating shaft of the mold-flipping bracket 26;

[0079] The fixed end of the flipping template 29 is connected to the inner side of the transfer bracket 24, and the movable end of the flipping template 29 extends towards the center of the transfer bracket 24. Furthermore, the supporting surface of the flipping template 29 gradually shrinks from a rectangular structure at the fixed end to a triangular structure at the movable end to increase friction and prevent the round cotton mold from slipping, utilizing the tip structure design of the flipping template 29. Simultaneously, to avoid the tip damaging the covering material of the round cotton mold, it is generally preferable to further round the tips of the flipping template and cover them with a layer of rubber material.

[0080] Through the above steps, this method can accurately identify the RFID tag information of the round cotton mold and effectively control the movement of the subcontracting mechanism. By triggering the subcontracting bracket 24, the round cotton mold is pushed onto the conveyor line 4 while its cutting area is flipped to a preset angle, achieving automated positioning and conveying of the round cotton mold. This method not only improves the accuracy of the round cotton mold cutting and transportation process but also reduces manual intervention and increases production efficiency. The subcontracting mechanism of this application has a high level of automation, strong motion continuity, accurate positioning, and ensures the safety performance of the production process.

[0081] In summary, this application, through its sequentially arranged storage, subcontracting, and conveying sections, enables automated processing of round cotton molds through the coordinated structure of these sections, thereby significantly improving work efficiency. Furthermore, the subcontracting mechanism utilizes RFID readers and various switching systems to accurately identify the tag information of the round cotton molds, pinpoint the cutting range, and ensure accuracy during the cutting process and smooth operation of subsequent tasks.

[0082] This application incorporates multiple photoelectric switches to enable automatic control of the entire process, ensuring smooth and precise operation, greatly improving work efficiency, effectively reducing manual intervention in the round cotton mold processing process, and meeting the automation needs of modern industrial production.

[0083] The above are merely embodiments of this application, and their descriptions are quite specific and detailed, but they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
