Abstract

The invention relates to automatic label receiving equipment and a labeling system. The automatic label receiving equipment comprises an unwinding mechanism and a pressing mechanism. The unwinding mechanisms are used for installing label rolls, and the number of the unwinding mechanisms is at least two. Materials unwound by the label rolls arranged on the unwinding mechanisms pass through the pressing mechanism, and the pressing mechanism is used for connecting the tail end of the material of the label roll arranged on one unwinding mechanism with the head end of the material of the label roll arranged on the other unwinding mechanism in a pressing mode. According to the automatic label receiving equipment and the labeling system, when the material of the label roll on one unwinding mechanism is used up and the tail end of the material of the label roll moves to the pressing mechanism, the pressing mechanism performs pressing action, so that the tail end of the material is quickly connected with the head end of the material of the label roll on the other unwinding mechanism in a pressing manner; in other words, the label roll on the other unwinding mechanism can be quickly put into use, so that replacement operation of the label roll can be realized without shutdown, and the working efficiency is improved.

Description

Technical Field

[0001] This application relates to the field of material feeding technology, and in particular to an automatic label receiving device and labeling system. Background Technology

[0002] To reflect product brand attributes or to display essential information such as production date, ingredients, and manufacturer on the product exterior, products undergo labeling before leaving the factory. Specifically, labels with printed images or text are affixed to designated locations on the product surface; this labeling process is typically completed using a labeling system.

[0003] In related technologies, the label roll is placed at the feeding station and gradually unwound under the drive of the drive roller, and then enters the inkjet or printing station. After being processed at the inkjet or printing station, the label paper carries key information such as production date, ingredients, and manufacturer. The processed material can be rewound or sent to the labeling station, where each label paper is peeled off and affixed to the corresponding product. The backing paper after peeling off the label paper is then rewound.

[0004] However, in this technology, the labeling system shuts down when the label rolls at the loading station are used up. It restarts after a new label roll is installed at the loading station. Because the loading speed is slow, this requires a period of downtime to resume normal operation, reducing work efficiency. Summary of the Invention

[0005] Therefore, it is necessary to address the shortcomings of existing technologies, such as downtime caused by changing label rolls, which reduces work efficiency, by providing an automatic label receiving device and labeling system that can improve work efficiency.

[0006] On one hand, this application provides an automatic label receiving device, the automatic label receiving device comprising:

[0007] An unwinding mechanism for mounting label rolls, wherein at least two unwinding mechanisms are provided; and

[0008] The pressing mechanism is used to press and connect the end of the label roll unwound by the unwinding mechanism to the beginning of the label roll on the other unwinding mechanism.

[0009] In one embodiment, the pressing mechanism includes:

[0010] Two carriers are arranged at a distance from each other, and each carrier has a supporting part on its side closest to the other. Each supporting part supports the material of one of the two label rolls.

[0011] A pressing member is disposed on any one of the carrier members, and the pressing member enables the material end on one of the carrier members to be pressed and connected to the material head on the other carrier member.

[0012] In one embodiment, at least one of the carrier members is provided with a first position and a second position, and can be switched and adjusted between the first position and the second position; when the carrier member is in the first position, the two carrier parts are arranged opposite to each other; when the carrier member is in the second position, the two carrier parts are arranged at an angle, and the distance between the two carrier members is greater than the distance between the two carrier parts when they are in the first position.

[0013] In one embodiment, the automatic labeling device further includes a workbench, one of the carriers is fixed to the workbench, and the other carrier is rotatably disposed on the workbench; the bearing portion of the other carrier includes a first bearing portion and a second bearing portion that are sequentially connected and arranged at an angle along the movement direction of the material, the distance between the first bearing portion and the bearing portion of one of the carriers decreases along the movement direction, and the second bearing portion is arranged parallel to the bearing portion of one of the carriers.

[0014] In one embodiment, the workbench is provided with a spare position and a working position. The spare position is correspondingly arranged with a support member fixed to the workbench along the direction of movement, and the working position is correspondingly arranged with a support member rotatably disposed on the workbench along the direction of movement. There are two unwinding mechanisms, one of which is detachably disposed in the spare position and the other is detachably disposed in the working position.

[0015] The workbench is also provided with a guide part that connects the spare position and the working position. When the unwinding mechanism of the working position is detached, the unwinding mechanism located in the spare position is guided to the working position via the guide part.

[0016] In one embodiment, the support portion is provided with an adsorption hole for communicating with a negative pressure device.

[0017] In one embodiment, the automatic labeling device further includes:

[0018] A driving mechanism is provided to drive the material movement of the label roll, thereby driving the unwinding mechanism to unwind the material; the unwinding mechanism, the pressing mechanism, and the driving mechanism are arranged sequentially along the material movement direction of the label roll; and

[0019] A first buffer mechanism is disposed downstream of the drive mechanism and is used to buffer the material.

[0020] In one embodiment, the automatic labeling device further includes a first sensor and a controller; the first sensor and the drive mechanism are both electrically connected to the controller; the first sensor is used to sense whether there is material upstream of the pressing member of the pressing mechanism, and the controller is used to control the pressing member to perform a pressing action when the first sensor does not sense the material.

[0021] In one embodiment, the automatic labeling device further includes a second sensor located upstream of the first sensor and electrically connected to the controller, which controls the drive mechanism to reduce its speed when the second sensor fails to detect the material.

[0022] On the other hand, this application also provides a labeling system, which further includes the aforementioned automatic label receiving device.

[0023] In the aforementioned automatic labeling equipment and labeling system, when the material of the label roll on one of the unwinding mechanisms is used up, and the material end of the label roll moves to the pressing mechanism, the pressing mechanism presses down, so that the material end is quickly pressed and connected to the material beginning of the label roll on the other unwinding mechanism. This means that the label roll on the other unwinding mechanism can be put into use quickly, and the label roll can be changed without stopping the machine, thereby improving work efficiency.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] As described in the background section, the label rolls at the loading station in the related technologies require machine downtime for replacement, resulting in slow loading speed and reduced work efficiency.

[0034] For the reasons mentioned above, this application provides an automatic labeling device and labeling system, which can improve the feeding speed and thus improve work efficiency.

[0035] Please see Figures 1 to 6 The following will Figures 1 to 6 The automatic labeling device and labeling system according to an embodiment of this application will be described in detail.

[0036] See Figure 1 This application provides an automatic label-receiving device, which includes an unwinding mechanism 10. The unwinding mechanism 10 is used to mount label rolls, serving to carry and support them, and can adaptively unwind when the label rolls are subjected to external forces. At least two unwinding mechanisms 10 are provided, for example, two, three, four, or more. This application specifically uses two unwinding mechanisms 10 as an example. When the label rolls of one unwinding mechanism 10 are in use, the label rolls on the other unwinding mechanism 10 are either reserved or fitted with brand-new, unused label rolls as reserves. When the label rolls of one unwinding mechanism 10 are used up, the label rolls of the other unwinding mechanism 10 are immediately put into use, and brand-new, unused label rolls are fitted to one unwinding mechanism 10 as reserves, and this process is repeated.

[0037] For example, the automatic labeling device also includes a drive mechanism 20. The drive mechanism 20 is used to drive the material movement of the label roll to drive the unwinding mechanism 10 to unwind. During the unwinding process of the unwinding mechanism 10, the material of the label roll will be gradually unwound and conveyed downstream.

[0038] In one embodiment, the label roll in this application comprises a base paper and multiple label sheets. The multiple label sheets are sequentially adhered to the base paper along the length of the base. The label sheets can be blank labels without any printed information, or labels printed with patterns or text information; there are no restrictions, and the settings can be flexibly adjusted and configured according to actual needs.

[0039] For example, the automatic label applicator also includes a pressing mechanism 30. The material unwound from the label roll mounted on the unwinding mechanism 10 travels through the pressing mechanism 30. In other words, the pressing mechanism 30 is arranged in the direction of material movement of the label roll. The direction of material movement refers to... Figure 6 The direction in which the red line extends.

[0040] Specifically, along the direction of material movement of the label roll, the pressing mechanism 30 is located between the unwinding mechanism 10 and the drive mechanism 20. When the label roll is unwound and the material is not used up, the pressing mechanism 30 is in a normally open state. Under the power of the drive mechanism 20, the material of the label roll is gradually unwound and normally conveyed downstream through the pressing mechanism 30 and the drive mechanism 20. Conversely, when the material of the label roll is used up, the end of the material moves to the pressing mechanism 30. The pressing mechanism 30 is used to press and connect the end of the material of the label roll mounted on one of the unwinding mechanisms 10 with the beginning of the material of the label roll mounted on the other unwinding mechanism 10. Specifically, there is an adhesive connection between the end of the material and the beginning of the material.

[0041] In the aforementioned automatic label receiving equipment, when the material of the label roll on one of the unwinding mechanisms 10 is used up, and the end of the material of the label roll moves to the pressing mechanism 30, the pressing mechanism 30 presses down, so that the end of the material is quickly pressed and connected to the beginning of the material of the label roll on the other unwinding mechanism 10. In other words, the label roll on the other unwinding mechanism 10 is quickly put into use, and the label roll can be changed without stopping the machine, thereby improving work efficiency.

[0042] For example, the pressing mechanism 30 includes two support members 31. The two support members 31 are arranged at a distance from each other, and a support portion 313 is provided on the side of the two support members 31 that is close to each other. The two support portions 313 correspond one-to-one to carry the material of the two label rolls. Under the support of the support portions 313, the material unwinding the label roll can run stably along the support portions 313. Furthermore, when the label roll on one of the unwinding mechanisms 10 is completely unwound, when the end of the material moves to one of the support members 31, the end of the material can be stably supported by the support member 31 to facilitate the pressing action and improve the accuracy of the material end and the material head joining together.

[0043] For example, the pressing mechanism 30 also includes a pressing member 32. The pressing member 32 can be a cylinder, a hydraulic cylinder, a motor screw, a cam mechanism, etc., and is not limited thereto. The pressing member 32 is provided on any one of the carrier members 31. The pressing member 32 can provide power so that the end of the material on one carrier part 313 is pressed and connected to the beginning of the material on another carrier part 313.

[0044] The pressing component 32 can be a single component, or two components respectively set on two carrier components 31, or more components. There is no restriction here, and it can be flexibly adjusted and set according to actual needs.

[0045] In this embodiment, to simplify the structure and reduce costs, the description will focus on a specific example where only one pressing component 32 and two unwinding mechanisms 10 are used. However, it is understood that the pressing component 32 and the unwinding mechanism 10 can each be configured in other quantities and combinations according to actual needs, as long as they can achieve the pressing and connection of the material head end and the material tail end together. All of these are within the protection scope of this application, and will not be elaborated upon in this embodiment.

[0046] Reducing the distance between the two support parts 313 also reduces the distance between the materials supported by the two support parts 313, resulting in a more stable and precise bonding between the material end and the material beginning. However, when the distance between the two support parts 313 is small, it is inconvenient to change the label roll, thus reducing production efficiency. Specifically, during the label roll change process, after the new label roll is installed into the unwinding mechanism 10, the material beginning needs to be inserted between the two support parts 31 to be installed on the support parts 31. During the insertion process, the small distance between the two support parts 31 can easily cause it to stick to the material in another unwinding process, leading to malfunctions and requiring machine shutdown for maintenance.

[0047] Based on this, at least one carrier 31 can be adjusted in position by various means including but not limited to rotation and translation, which can increase the distance between the two carrier parts 313, thereby facilitating the replacement of label rolls; and can also reduce the distance between the two carrier parts 313, thereby making the material end and the material beginning more stably and precisely pressed together.

[0048] In one specific embodiment, at least one support member 31 is provided with a first position and a second position, and can be switched and adjusted between the first position and the second position. Optionally, one support member 31 has a fixed position, while the other support member 31 is adjusted between the first position and the second position by rotating counterclockwise or clockwise. The rotation center point of the support member 31 is as follows: Figure 4 or Figure 5 As shown in O. Furthermore, the rotation angle of the support member 31 can be, for example, 60°, 90°, 120°, or 180°, etc., and is not limited here. Please refer to... Figure 4 When the support member 31 is in the first position, the two support parts 313 are arranged opposite each other; please refer to Figure 5 When the carrier 31 is in the second position, the two carrier portions 313 are arranged at an angle, and the distance S2 between the two carriers 31 is greater than the distance S1 between the two carrier portions 313 when they are in the first position. Thus, when the label roll needs to be replaced, the carrier 31 is switched to the second position, providing ample space to mount the beginning of the label roll onto the carrier portion 313; when the label roll is replaced, the carrier 31 is switched to the first position, resulting in a smaller distance between the two carrier portions 313, which facilitates subsequent pressing and connection operations.

[0049] In another specific embodiment, at least one support member 31 is provided with a first position and a second position, and can be switched and adjusted between the first position and the second position. Optionally, the position of one support member 31 is fixed, and the other support member 31 can be translated in a direction closer to or farther from the first support member 31 to adjust the distance between the two. When the support member 31 is in the first position, the distance between the two support parts 313 is a first distance; when the support member 31 is in the second position, the distance between the two support parts 313 is a second distance; the first distance is smaller than the second distance.

[0050] Of course, it is understandable that in some alternative solutions, the positions of each load-bearing component 31 can be adjusted according to actual needs, and this application does not impose any restrictions on this.

[0051] Please see Figure 4 and Figure 5For example, the automatic labeling device also includes a worktable 40. One support member 31 is fixed to the worktable 40, and the other support member 31 is rotatably disposed on the worktable 40. Specifically, the support member 31 fixed to the worktable 40 is designated as the first support member 311, and the support member 31 rotatably disposed on the worktable 40 is designated as the second support member 312. The supporting portion 313 of the first support member 311 is, for example, a plane, which can stably support and guide the material. The label rolls that are in normal operation correspond to the first support member 311, and the spare label rolls correspond to the second support member 312, such that the first support member 311 is preferably arranged below the second support member 312. Of course, the first support member 311 and the second support member 312 can also be arranged in other ways, which are not limited here.

[0052] Please see Figure 4 For example, the support portion 313 of the second support member 312 includes a first support portion 3131 and a second support portion 3132 connected sequentially along the material movement direction and arranged at an angle. The distance between the first support portion 3131 and the support portion 313 of the first support member 311 decreases along the movement direction, and the second support portion 3132 is arranged parallel to the support portion 313 of the first support member 311. In this way, interference with the first support member 311 can be avoided during the rotation adjustment of the second support member 312. Furthermore, the small distance between the second support portion 3132 and the support portion 313 of the first support member 311 is beneficial for realizing the pressing connection operation between the beginning and end of the material.

[0053] For example, the workbench 40 is provided with a spare position and a working position. The spare position is arranged in the direction of movement corresponding to the support member 31 fixed to the workbench 40, and the working position is arranged in the direction of movement corresponding to the support member 31 rotatably mounted on the workbench 40. There are two unwinding mechanisms 10, one of which is detachably mounted in the spare position and the other is detachably mounted in the working position. That is, the label rolls on the unwinding mechanism 10 mounted in the spare position are used as spares, and the material head end of the label roll is supported by the second support member 312. The label rolls on the unwinding mechanism 10 mounted in the working position are in a loose-wound working state, and the material of the label roll passes through the first support member 311 and is supported and guided by the first support member 311. When the label rolls on the unwinding mechanism 10 in the working position are used up, the unwinding mechanism 10 in the working position is detached, the unwinding mechanism 10 in the spare position is adjusted to the working position, and the label rolls on the unwinding mechanism 10 in the spare position are put into use. Furthermore, after the label roll is installed on the disassembled or new unwinding mechanism 10, it is moved to the spare position for backup. By repeating this cycle, continuous operation can be achieved, with fast material feeding and high production efficiency.

[0054] In order to quickly adjust the unwinding mechanism 10 in the standby position to the working position, based on the aforementioned embodiment, the worktable 40 is also provided with a guide portion 41 connecting the standby position and the working position. The guide portion 41 includes, but is not limited to, guide rails, slides, etc., and is not limited here. When the unwinding mechanism 10 in the working position is detached, the unwinding mechanism 10 in the standby position is guided to the working position via the guide portion 41.

[0055] The spare position is located above the working position.

[0056] When the label rolls on the unwinding mechanism 10 at the working station are used up, the unwinding mechanism 10 at the working station is manually detached. The automatic label receiving equipment also includes a sensor 90. The sensor 90 is, for example, a photoelectric sensor, and is used to sense when the unwinding mechanism 10 at the working station is detached, and to adjust the unwinding mechanism 10 located in the standby position to the working position.

[0057] Of course, as an optional solution, each unwinding mechanism 10 can also be fixedly set on the worktable 40. When the label rolls on one of the unwinding mechanisms 10 run out, they are replaced promptly. Furthermore, during the label roll replacement process, label rolls from the other unwinding mechanism 10 are put into use. In this way, non-stop operation, fast feeding speed, and high production efficiency can be achieved.

[0058] It should be noted that the carrier 313 can carry materials in various ways, including but not limited to vacuum adsorption and magnetic attraction, and no limitation is made here. In this embodiment, vacuum adsorption will be used as an example for detailed description.

[0059] Based on the aforementioned embodiment, the support portion 313 is provided with adsorption holes for communication with a negative pressure device. The adsorption holes can generate negative pressure to adsorb materials, effectively preventing the materials carried on the two support portions 313 from getting close to each other and sticking together before pressing the material head end and material tail end together.

[0060] The number of adsorption holes is not limited to one, but can be, for example, multiple. When there are multiple adsorption holes on the support part, the adsorption effect can be improved, allowing the material to adhere smoothly to the support part 313. Specifically, for the first support member 311, the adsorption part of the first support member 311 can stably adsorb the material, preventing the material from tilting upwards and affecting subsequent connection operations. For the second support member 312, the adsorption part of the second support member 312 can stably adsorb the beginning of the material, preventing the beginning of the material from falling off and prematurely connecting with the material carried by the first support member 311.

[0061] Please see Figure 4 and Figure 5For example, the drive mechanism 20 includes a drive roller 21 and a pressure roller 22. The drive roller 21 and the pressure roller 22 are in contact with each other, and when the drive roller 21 rotates, it drives the pressure roller 22 to rotate synchronously. The drive roller 21 abuts against one side of the material, and the pressure roller 22 abuts against the other side of the material. When the drive roller 21 rotates, it can drive the material to move.

[0062] During the pressing operation of the pressing mechanism 30 on the material end and the material front end, the drive mechanism 20 stops or moves at a low speed to ensure pressing quality. When the speed of the drive mechanism 20 decreases, to ensure a continuous supply of material and allow it to enter the subsequent processing station without stopping the machine, the automatic labeling equipment, for example, also includes a first buffer mechanism 50. The first buffer mechanism 50 is located downstream of the drive mechanism 20 and can be used to buffer material. Thus, when the speed of the drive mechanism 20 decreases, the material stored in the first buffer mechanism 50 can continue to be supplied to the subsequent processing station. When the speed of the drive mechanism 20 increases, the material will be stored in the first buffer mechanism 50.

[0063] Optionally, a first buffer mechanism 50 is mounted on a worktable 40. The worktable 40 has a first buffer slide 42, which extends, for example, in the vertical direction Z. The first buffer mechanism 50 includes a first sliding wheel 51. The first sliding wheel 51 is slidably disposed on the first buffer slide 42. Material is arranged around the first sliding wheel 51. When the speed of the drive mechanism 20 decreases, the tension of the material increases, causing the first sliding wheel 51 to move upward along the first buffer slide 42, thus supplying material to subsequent workstations. When the speed of the drive mechanism 20 increases, the first sliding wheel 51 moves downward along the first buffer slide 42, thus storing the material. By adjusting the speed of the drive mechanism 20, the height position of the first sliding wheel 51 on the first buffer slide 42 can be adaptively adjusted.

[0064] It should be noted that subsequent workstations have been omitted in the attached diagram, including but not limited to inkjet printing workstations, labeling workstations, etc. There are no restrictions here, and the specific workstations can be flexibly adjusted and set according to actual needs.

[0065] Based on the foregoing embodiments, the first buffer mechanism 50 further includes a first guide wheel 52. The first guide wheel 52 is rotatably disposed on the worktable 40. Both the drive mechanism 20 and the first guide wheel 52 are located above the first buffer slide 42.

[0066] For example, the automatic label-attaching device also includes a first sensor and a controller. The first sensor includes, but is not limited to, a photoelectric sensor. Both the first sensor and the drive mechanism 20 are electrically connected to the controller. The first sensor is used to sense whether there is material upstream of the pressing member 32. During the unwinding of the label roll, the material passes through the pressing mechanism 30. If there is material upstream of the pressing member 32, the first sensor can continuously generate a sensing signal, indicating that the material of the label roll has not been completely unwound, and there is no need to control the pressing action of the pressing member 32. Conversely, when there is no material upstream of the pressing member 32, the first sensor will not generate a sensing signal, which means that the material of the label roll has been completely unwound and the end of the material has entered the position corresponding to the pressing member 32. The controller controls the pressing member 32 to perform the pressing action, so that the end of the material and the beginning of the material are accurately pressed and connected together.

[0067] It should be noted that in this embodiment, "upstream" refers to the position along the unwinding path of the material, closer to the unwinding mechanism 10; conversely, "downstream" refers to the position along the unwinding path of the material, further away from the unwinding mechanism 10.

[0068] Based on the aforementioned embodiments, the automatic label-attaching device further includes a second sensor. The second sensor includes, but is not limited to, a photoelectric sensor. The second sensor is located upstream of the first sensor and is electrically connected to the controller. During the unwinding process of the label roll, the material sequentially passes through the second sensor. The second sensor continuously generates a sensing signal, indicating that the material in the label roll is not completely unwound, thus eliminating the need to control the drive mechanism 20 to reduce its speed. Conversely, when there is no material upstream of the first sensor, the second sensor will not generate a sensing signal, meaning that the material in the label roll is completely unwound and about to enter the position corresponding to the pressing member 32. In this case, the controller controls the drive mechanism 20 to reduce its speed. This improves the pressing accuracy between the end and beginning of the material.

[0069] In one specific embodiment, the second sensor, the first sensor, and the pressing member 32 are arranged sequentially along the direction of material movement. Specifically, both the second sensor and the first sensor are disposed on the first support member 311. The pressing member 32 is disposed on the second support member 312. During the pressing action, the pressing member 32 provides power to cause the material head end of the spare label roll to move downward and press and adhere together with the material tail end carried on the first support member 311.

[0070] In some embodiments, the automatic labeling equipment further includes at least two recycling mechanisms 60. After the material from the unwinding mechanism 10 is unwound, it undergoes various processing steps at subsequent stations and then enters the recycling mechanism 60, where it is wound and recycled. Specifically, when one recycling mechanism 60 is full, the backing paper is manually cut, pulled, and wound into the other recycling mechanism 60, where it is wound and recycled, thus improving the recycling efficiency of the backing paper.

[0071] By placing both the recycling mechanism 60 and the unwinding mechanism 10 on the same workbench 40, the overall structure can be simplified and the cost reduced.

[0072] Based on the aforementioned embodiments, the automatic labeling device further includes a second buffer mechanism 70. The second buffer mechanism 70 is installed on the workbench 40 and is located upstream of the recycling mechanism 60. After being buffered by the second buffer mechanism 70, the material is then output to the recycling mechanism 60. Thus, when one recycling mechanism 60 has finished collecting the material, the buffering effect of the second buffer mechanism 70 allows the processed material to be transferred to the other recycling mechanism 60 without shutting down the machine, where the other recycling mechanism 60 will perform the recycling operation.

[0073] Based on the aforementioned embodiment, the worktable 40 is provided with a second buffer slide 43, which extends, for example, in the vertical direction Z. The second buffer mechanism 70 includes a second sliding wheel 71. The second sliding wheel 71 is slidably disposed on the second buffer slide 43. The material is arranged around the second sliding wheel 71. In this way, the second sliding wheel 71 can move along the second buffer slide 43, thereby providing buffer space for the processed material.

[0074] When the recycling mechanism 60 has finished collecting the material, during the process of changing the material to another recycling mechanism 60, the second sliding wheel 71 moves downward along the second buffer slide 43 to achieve gradual buffering of the material; after the material is changed to another recycling mechanism 60, by increasing the recycling speed of the recycling mechanism 60, the second sliding wheel 71 moves upward along the second buffer slide 43, thereby increasing the buffer space.

[0075] Specifically, the automatic tag receiving device also includes a third sensor 80. The third sensor 80 is electrically connected to the controller. The third sensor 80 is used to sense whether the second sliding wheel 71 is located at the top of the second buffer slide 43. When the second sliding wheel 71 descends, the third sensor 80 will no longer detect it, and the controller will correspondingly control the recovery mechanism 60 to increase its rotation speed, causing the second sliding wheel 71 to move upwards along the second buffer slide 43. When the third sensor 80 can detect the second sliding wheel 71, the speed of the recovery mechanism 60 remains constant. Therefore, the second sliding wheel 71, located at the top of the second buffer slide 43, has a large buffer space.

[0076] To increase stability, the second buffer mechanism 70 also includes a mounting base 72. The mounting base 72 is slidably disposed on the second buffer slide 43. Multiple second sliding wheels 71 are provided and mounted on the mounting base 72. Material passes through each of the second sliding wheels 71.

[0077] Based on the aforementioned embodiments, the second buffer mechanism 70 further includes a second guide wheel 73. The second guide wheel 73 is arranged adjacent to the top of the second buffer slide 43. The material after post-processing is arranged around the second guide wheel 73 and guided by the second guide wheel 73 to the second sliding wheel 71.

[0078] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0079] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0080] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0081] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0082] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
