DETAILED DESCRIPTION

[0028] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with examples and drawings, and the content mentioned in the implementation manner is not the limitation of the utility model.

[0029] Please refer to Figures 1 to 9 The utility model discloses a top and bottom cover paperboard belt feeding mechanism, including bearing frame 3, rotation setting bearing frame 3 on pushing belt 5 and being used for driving pushing belt 5 to rotate the second driving device 6, pushing belt 5 is used for resisting paperboard, and pushing belt 5 realizes pushing action to paperboard through the drive of second driving device 6.

[0030] In actual use, the design of the pushing belt 5 can provide a relatively stable and continuous pushing force. Compared with some intermittent feeding methods, it can keep the paperboard moving at a relatively uniform speed during the feeding process, reducing problems such as paperboard accumulation, jamming or misalignment caused by fluctuations in feeding speed, thereby improving the stability and reliability of the feeding link on the entire top and bottom cover paperboard production line, ensuring that the subsequent processing procedures can be carried out in an orderly and efficient manner. Since the pushing belt 5 is rotatably arranged on the carrier frame 3 and driven by the second driving device 6, this structure is relatively simple and easy to control. The speed and other parameters of the second driving device 6 can be accurately adjusted according to actual production needs, thereby precisely controlling the pushing speed of the pushing belt 5, adapting to paperboard feeding tasks of different specifications and different production rhythms, ensuring that the feeding speed matches the processing speed of other links of the production line, and avoiding low production efficiency or product quality problems caused by too fast or too slow feeding. The pushing belt 5 directly contacts the paperboard and performs the pushing action, and compared with some rigid pushing structures (such as pushing plates, etc.), the pushing belt 5 has a certain flexibility. During the pushing process, it can better fit the surface of the paperboard, uniformly distribute the pushing force, and reduce the local pressure and friction on the surface of the paperboard, thereby effectively reducing the risk of scratching, indentation or damage to the paperboard during the feeding process, and being beneficial to ensuring the appearance quality of the paperboard and improving the yield of the product. The continuous and stable pushing of the pushing belt 5 also helps to reduce the shaking and vibration of the paperboard during the feeding process. Excessive shaking and vibration can damage the internal structure of the paperboard, affecting the strength and stability of the paperboard, and this belt feeding mechanism can to some extent avoid such problems, ensuring that the paperboard enters the subsequent processing procedures such as printing, molding, etc. in good condition. The structural design of the feeding mechanism has a certain universality. As long as the width, length of the pushing belt 5 and the parameters of the second driving device 6 are adjusted, it can be applied to feeding of different sizes and types of top and bottom cover paperboard, without the need for large-scale redesign and modification of the entire feeding system, reducing the equipment adjustment cost and time cost of enterprises in producing different products, improving the utilization rate of equipment and the flexibility of production.

[0031] Specifically, the top and bottom cover paperboard belt feeding mechanism further comprises a first driving device 4 for driving the carrier frame 3 to reciprocate, and the first driving device 4 drives the carrier frame 3 to move the pushing belt 5, so that the pushing belt 5 cooperates with the external paperboard to resist and touch.

[0032] In actual use, the first driving device 4 enables the carrier frame 3 to reciprocate, which greatly expands the range that the pushing belt 5 can reach. In the context of feeding the top and bottom cover paperboard, the paperboard may be distributed in a large area. Through the reciprocating movement of the carrier frame 3, the pushing belt 5 can flexibly cooperate with the paperboard at different positions and perform the pushing operation, instead of being limited to a small fixed area. This can more comprehensively and efficiently collect and supply the scattered paperboard, reduce the need for frequent manual intervention and adjustment due to slight differences in the placement position of the paperboard, and improve the degree of automation and feeding efficiency. This reciprocating carrier frame 3 design has strong adaptability to different production workshop layouts and paperboard storage methods. Whether the paperboard is arranged in a straight line, scattered in different areas, or placed in a specific group, the carrier frame 3 can adjust its position under the action of the first driving device 4, so that the pushing belt 5 accurately interfaces with the paperboard, thereby easily integrating into various existing or future possible adjusted production process flows and workshop layouts. This eliminates the need to make large-scale changes to the entire production layout to adapt to fixed feeding mechanisms, reduces the difficulty and cost of production system integration, and enhances the versatility and compatibility of the feeding mechanism in different production environments.

[0033] Specifically, the top and bottom cover paperboard belt feeding mechanism further comprises a rack 2, a load table 7 for carrying the paperboard to be fed is slidably arranged on the rack 2, and a third driving device 8 for driving the load table 7 to reciprocate on the rack 2. The third driving device 8 drives the load table 7 so that the paperboard on the load table 7 cooperates with the pushing belt 5.

[0034] In actual use, the loading table 7 provides a unified bearing platform for the paperboard to be fed, so that the paperboard that may be scattered and placed at different angles can be placed on the loading table 7. The third driving device 8 drives the loading table 7 to slide back and forth, and in this process, the paperboard can be arranged and aligned automatically by means of the movement of the loading table 7 and the cooperation with the surrounding limiting structure (if provided), so that the subsequent pushing belt 5 can accurately and neatly contact and push the paperboard, reducing the problems of skewing and jamming in the feeding process caused by the initial irregular placement of the paperboard, and improving the accuracy and orderliness of feeding. By controlling the position of the loading table 7 through the third driving device 8, the paperboard on the loading table 7 can be accurately positioned at the appropriate feeding starting position, so that the initial contact point of the pushing belt 5 reaches the best state. In this way, it can be ensured that each pushing operation starts from an accurate and ideal position, further ensuring the stability and standardization of the entire feeding process, which helps to improve the yield and production efficiency of the subsequent top and bottom cover paperboard processing process. The loading table 7 can carry a certain number of paperboard to be fed, and when the frontmost paperboard is pushed away by the pushing belt 5, the third driving device 8 can timely drive the loading table 7 to slide, quickly and smoothly supplementing the subsequent paperboard to the action area of the pushing belt 5, ensuring the continuity of feeding and avoiding the interruption and pause of feeding caused by frequent replenishment of individual paperboard. Especially on a high-speed production line, this continuous feeding capability can better match the pace of the production line, so that the entire top and bottom cover paperboard production process runs uninterruptedly, maximizing the output per unit of time. Regardless of the size and thickness of the paperboard, as long as the size of the loading table 7 is reasonably designed, the corresponding paperboard can be placed thereon. The movement mode of the third driving device 8 driving the loading table 7 is not affected by the specifications of the paperboard, and the paperboard can still accurately cooperate with the pushing belt 5. This makes the feeding mechanism have strong versatility.

[0035] Specifically, the bearing frame 3 and the first driving device 4 are arranged on the rack 2, and the bearing frame 3 is arranged above the loading table 7. The bearing frame 3 drives the pushing belt 5 and the loading table 7 to move closer to or away from each other through the driving of the first driving device 4 and the third driving device 8, so as to adjust the position between the pushing belt 5 and the paperboard carried on the loading table 7.

[0036] In actual use, the top and bottom cover paperboard can have different thickness specifications. By driving the carrier frame 3 and the loading table 7 to move closer to or away from each other through the first driving device 4 and the third driving device 8, the distance between the pushing belt 5 and the paperboard can be accurately adjusted. For thicker paperboard, the distance between the two can be appropriately increased to ensure that the pushing belt 5 can effectively push the paperboard without causing damage to the paperboard due to excessive pressure caused by too close a distance. For thin paperboard, the distance can be reduced to ensure that the pushing belt 5 is in good contact with the paperboard to achieve stable pushing, thereby well adapting to the feeding needs of paperboard of various thicknesses and improving the accuracy and effectiveness of feeding. Even if the top and bottom cover paperboard provided by different suppliers has approximately the same specifications, there can be some differences in actual size, flatness, and other details. By using the function of adjusting the position of the carrier frame 3 and the loading table 7 through relative movement, adaptive adjustments can be quickly made to the characteristics of paperboard from different suppliers, enabling the mechanism to smoothly accept and push these paperboard with slight differences for feeding, expanding the range of paperboard sources that the equipment can accommodate, reducing the likelihood of production being affected by different paperboard sources, and improving the versatility and compatibility of the equipment in the entire supply chain environment.

[0037] Specifically, the pushing belt 5 is provided with protrusions 51 that cooperate with the paperboard to increase the friction between the two. The number of protrusions 51 is multiple, and the protrusions 51 are arranged along the length direction of the pushing belt 5.

[0038] In actual use, the protrusions 51 can increase the friction between the pusher belt 5 and the paperboard during the pushing process. Compared to the smooth surface of the pusher belt 5, this design makes the pusher belt 5 less likely to slip when rotating to push the paperboard. Regardless of the material and roughness of the paperboard surface, the protrusions 51 can better "grasp" the paperboard, ensuring that the pusher belt 5 exerts a stable and continuous pushing force on the paperboard, causing the paperboard to move in the expected direction and speed. This ensures a smooth and orderly feeding process, effectively reducing problems such as paperboard accumulation and jamming caused by unstable pushing, and improves the reliability of the entire top and bottom cover paperboard feeding link. Due to the increased friction of the protrusions 51, the displacement of the paperboard can be more accurately controlled when pushing the paperboard. For top and bottom cover paperboards that need to be accurately fed into subsequent processing procedures, the accuracy of each pushing is crucial. The protrusions 51 can ensure that the paperboard moves strictly according to the set route and distance under the action of the pusher belt 5, reducing small displacement deviations caused by insufficient friction, and helping to accurately deliver the paperboard to the designated location, improving the processing precision and product quality of subsequent processes (such as printing, molding, etc.), and meeting the high requirements of top and bottom cover paperboards for size, position accuracy, etc. With the increased friction of the protrusions 51, the pusher belt 5 can appropriately increase the rotation speed to speed up the pushing rhythm without slipping and other problems. Under the premise of ensuring that the paperboard can be stably pushed, faster pushing speed means that more paperboards can be delivered per unit of time, thereby improving the feeding efficiency of the entire top and bottom cover paperboard production line.

[0039] Specifically, the carrier frame 3 is provided with a sensor 33 for detecting the position of the paperboard to be fed on the loading table 7. The number of pusher belts 5 is multiple, and the multiple pusher belts 5 are provided with gaps that expose the sensor 33 and the paperboard. The position information of the paperboard detected by the sensor 33 triggers the second driving device 6 to drive the pusher belt 5 to automatically replenish and push the paperboard after the pusher belt 5 completes a pushing action.

[0040] In actual use, the sensor 33 arranged on the bearing frame 3 can detect the position of the paperboard to be fed on the loading table 7 in real time, which makes the entire feeding process controllable. No matter how the paperboard is initially placed on the loading table 7, whether it is arranged in order or slightly offset, the sensor 33 can accurately position and provide accurate starting basis for subsequent pushing action, avoiding problems such as paperboard pushing not smooth and paper jam caused by blind pushing, ensuring that each time of pushing is based on clear knowledge of the position of the paperboard, greatly improving the accuracy and orderliness of feeding. The paperboard position information detected by the sensor 33 can directly trigger the second driving device 6 to drive the pushing belt 5 to push, realizing automatic and accurate matching of the pushing action and the position of the paperboard. When the paperboard on the loading table 7 is in the appropriate starting position for pushing, the pushing belt 5 can start pushing in time, without the situation of pushing too early or too late, ensuring that the entire feeding process is carried out according to the ideal rhythm, which helps to maintain a stable production rhythm, improves the production efficiency of the top and bottom cover paperboard, and can better coordinate with the rhythm of the subsequent processing procedures. After the pushing belt 5 completes a pushing action, automatic feeding and pushing again can be realized by the detection of the sensor 33 and the cooperation with the loading table 7. This automatic and cyclic feeding mechanism does not need to pay attention to the remaining amount of paperboard and the pushing situation at all times, reduces the frequency of manual intervention, greatly improves the automation degree of the feeding link, and makes the entire production process of the top and bottom cover paperboard more smooth and efficient.

[0041] Specifically, two second limiting plates 9 arranged in parallel on the rack 2 reciprocate, two fourth driving devices 10 are arranged for driving the two second limiting plates 9 to reciprocate, the two second limiting plates 9 limit the freedom of the plane where the paperboard is located perpendicular to the pushing direction, and the two fourth driving devices 10 drive the two second limiting plates 9 to reciprocate synchronously to cooperate with the pushing action of the pushing belt 5 and realize accurate feeding of paperboards of different sizes.

[0042] In actual use, by arranging two second limiting plates 9 on the rack 2 in parallel and using them to limit the freedom of the plane where the paperboard is located perpendicular to the pushing direction, combined with the previous limiting of the paperboard in the thickness direction by the pushing belt 5 and the loading table 7 and the limiting of the paperboard in the pushing direction by the pushing belt 5, precise limiting of the paperboard in multiple dimensions is achieved. This can ensure that the paperboard is always in an accurate and stable position during the entire feeding process, avoiding position deviation, skew and other situations, greatly improving the accuracy of the paperboard feeding position and providing a good material basis for subsequent processes such as lid production. Two fourth driving devices 10 are configured to drive the two second limiting plates 9 to move synchronously, so that the distance between the two limiting plates can be flexibly adjusted according to paperboards of different sizes. Whether the paperboard is large or small in size, it can be precisely fed by adjusting the position of the second limiting plate 9 to limit it appropriately, thereby cooperating with the pushing action of the pushing belt 5 to achieve precise feeding of paperboards of various sizes. This flexibility enhances the compatibility of the feeding mechanism for paperboards of multiple specifications, broadens its application range, and reduces the trouble and cost of replacing different feeding equipment due to different paperboard sizes. Precise limiting and good adaptation to paperboards of different sizes enable the paperboard to move in an orderly and neat manner during the pushing process by the pushing belt 5, avoiding problems such as paper jamming and paperboard stacking disorder caused by size mismatch or poor limiting, ensuring smooth feeding. Smooth feeding helps maintain efficient operation of the entire production process, reduces time waste caused by poor feeding, and improves overall production efficiency. Since precise feeding of paperboards of different sizes can be achieved, subsequent production processes such as lid production using these paperboards can ensure that the paperboard raw materials used by each product meet the requirements in terms of feeding position and state, which is conducive to maintaining product quality stability and avoiding product quality fluctuations caused by paperboard feeding problems.

[0043] Specifically, the rack 2 is provided with a feeding belt 11 rotating thereon, and a fifth driving device 12 for driving the feeding belt 11 to rotate. The feeding belt 11 is arranged at the end of the pushing belt 5. The fourth driving device 10 has a screw rod 101 rotatingly arranged on the rack 2, and a driver 102 for driving the screw rod 101 to rotate. A third limiting plate 103 is screwed on the screw rod 101. The third limiting plate 103 is connected with the second limiting plate 9 and is arranged along the feeding direction for limiting the paperboard pushed by the pushing belt 5 onto the feeding belt 11.

[0044] In actual use, a feeding belt 11 is arranged at the end of the pushing belt 5. When the pushing belt 5 finishes pushing the paperboard, the feeding belt 11 can continue to convey the paperboard, so that the feeding process of the paperboard is seamlessly connected, avoiding the situation that the paperboard stops and accumulates due to the lack of subsequent conveying power after the pushing is finished, ensuring the continuity and smoothness of the entire feeding process, and stably conveying the required paperboard raw material for the subsequent production of top and bottom covers and other related processes. The design of the pushing belt 5 cooperating with the feeding belt 11 meets the actual process requirements of the paperboard feeding of the top and bottom cover. The belt conveying at different stages can better adapt to the feeding requirements at different positions and under different working conditions, such as the pushing belt 5 focusing on pushing the paperboard out from the loading table 7, and the feeding belt 11 focusing on stably feeding the pushed paperboard to the designated position of the subsequent process. The two complement each other, optimizing the path and efficiency of the entire feeding. Through the design of the screw rod 101, the driver 102 and the third limiting plate 103 screwed with the screw rod 101 of the fourth driving device 10, the third limiting plate 103 is arranged along the feeding direction, which is combined with the limiting of the second limiting plate 9 perpendicular to the pushing direction of the paperboard, to further limit the paperboard in different directions in the plane. This can more comprehensively and accurately control the position of the paperboard on the feeding belt 11, prevent the paperboard from deviating or mispositioning during conveying, and ensure that the paperboard can be conveyed to the designated location in the correct direction, improving the accuracy of feeding. The screw rod 101 and the third limiting plate 103 are screwed, so that the position of the third limiting plate 103 can be flexibly adjusted according to paperboards of different sizes. When the driver 102 drives the screw rod 101 to rotate, the third limiting plate 103 will move along the screw rod 101 accordingly, thereby changing its limiting position in the feeding direction to adapt to paperboards of different lengths and specifications, enhancing the compatibility of the entire feeding mechanism for paperboards of various sizes and better meeting diversified production requirements. The fourth driving device 10 adopts the mechanical structure of the screw rod 101 rotating on the rack 2 and the corresponding driver 102, which has high stability and reliability. Its transmission process is relatively accurate and stable, and is not prone to slipping and other unstable situations. Moreover, this structure is convenient for accurate position adjustment and control. The operator can accurately adjust the position of the third limiting plate 103 by controlling the driver 102, which is relatively simple and easy to operate, and is conducive to improving the control performance and overall operation stability of the equipment in actual use.

[0045] Specifically, the rack 2 is provided with a rotating shaft 13, and a roller 14 for assisting the feeding belt 11 in feeding is arranged on the rotating shaft 13. The roller 14 is arranged on the feeding belt 11 near one end of the pushing belt 5 and above the feeding belt 11.

[0046] In actual use, a roller 14 is arranged above the end of the feeding belt 11 close to the pushing belt 5, which can exert a certain downward pressure on the paperboard passing through this position, so that the friction between the paperboard and the feeding belt 11 is increased. During the process of the feeding belt 11 conveying the paperboard, the additional pressure provided by the roller 14 can more effectively drive the paperboard to move forward, effectively avoiding the paperboard from slipping or stagnating at the joint or during the initial feeding stage, further ensuring the smoothness of feeding and ensuring that the paperboard can be continuously conveyed along the feeding belt 11. The roller 14 is located at the key position where the feeding belt 11 connects with the pushing belt 5, and its auxiliary feeding function can make the paperboard pushed from the pushing belt 5 transition better to the feeding belt 11. Especially for some paperboards with hard texture or relatively smooth surface, the roller 14 can help them quickly and smoothly enter the normal conveying state of the feeding belt 11, realize a more close and smooth connection between the pushing belt 5 and the feeding belt 11, and ensure that the entire feeding process will not be stalled at this position, maintaining the continuity of material supply. The roller 14 shares part of the friction and pressure between the paperboard and the feeding belt 11, which is originally only borne by the feeding belt 11, and when a large amount of paperboard continuously passes through this position, it can reduce the stress on the surface of the feeding belt 11 and reduce the probability of wear and aging of the feeding belt 11 due to long-term high pressure and friction. This helps to prolong the service life of the feeding belt 11, reduce the cost investment and impact on production continuity caused by frequent replacement of the feeding belt 11, and ensures the long-term stable operation of the entire feeding mechanism. In addition to assisting feeding, the appropriate pressure exerted by the roller 14 on the paperboard can also limit the vertical movement of the paperboard to some extent, making the conveying posture of the paperboard on the feeding belt 11 more stable. In the subsequent conveying process, the paperboard is less likely to come off the feeding belt 11 or collide with surrounding components due to unstable conditions such as jumping up and down, improving the stability of the paperboard position during the entire feeding process and helping to more accurately convey the paperboard to the designated position of the subsequent process.

[0047] Specifically, the frame 2 is slidably provided with a reciprocating transition frame 15 and a sixth driving device 16 for driving the transition frame 15 to slide reciprocally on the frame 2. The transition frame 15 is arranged between the end of the pushing belt 5 and the starting end of the feeding belt 11 to assist the transition of the paperboard from the pushing belt 5 to the feeding belt 11. The sixth driving device 16 adjusts the position of the transition frame 15 to adapt to paperboards of different sizes.

[0048] In actual use, a transition frame 15 is arranged between the end of the pushing belt 5 and the starting end of the feeding belt 11 to provide a transition area for the paperboard to transfer from the pushing belt 5 to the feeding belt 11. After the paperboard is pushed by the pushing belt 5, the transition frame 15 can receive and guide the paperboard to enter the feeding belt 11 more smoothly, avoiding the situation that the paperboard may be jammed or dropped due to direct conversion at the interface, making the entire feeding process more smooth at this key connection point, and ensuring the continuity of material conveying. The transition frame 15 plays a role in buffering and transition, which can effectively reduce the collision force between the paperboard and the edge of the feeding belt 11 or other components during the transfer, reduce the risk of damage or deformation of the paperboard due to collision, and ensure that the paperboard delivered to the subsequent process maintains good integrity, which helps to improve the quality of the subsequent products such as top and bottom covers. The position of the transition frame 15 is adjusted by the sixth driving device 16, so that the transition frame 15 can be flexibly changed according to paperboards of different sizes. Whether the paperboard is larger in size and needs a wider transition space, or smaller in size and requires more accurate positioning, the transition frame 15 can be adjusted in position to meet the corresponding requirements, enhancing the adaptability of the entire feeding mechanism to paperboards of various sizes and reducing the problem of poor feeding caused by differences in paperboard size. The transition frame 15 can also play a certain positioning role for the paperboard while assisting in the transition, ensuring that the paperboard is in the correct position when entering the feeding belt 11, so that the subsequent conveying path of the paperboard on the feeding belt 11 is more accurate. This can avoid the situation that the paperboard deviates or misplaces during feeding, improving the accuracy of feeding and providing positionally accurate paperboard raw materials for subsequent processes, which is conducive to ensuring the standardization and consistency of product manufacturing.

[0049] In the embodiment, the carrier frame 3 is provided with a vibration member 32 attached to the bottom surface of the pushing belt 5, and two first limiting plates 31 are arranged on both sides of the vibration member 32 to limit the freedom of the pushing belt 5 in the width direction.

[0050] In actual use, the vibration member 32 arranged on the bearing frame 3 is in close contact with the bottom surface of the pushing belt 5. This close contact design can ensure that the vibration generated by the first driving device 4 driving the bearing frame 3 is efficiently transmitted to the pushing belt 5. The energy loss in the vibration transmission process is small, so that the vibration on the pushing belt 5 is more sufficient and uniform, thereby more effectively solving the problem of paperboard sticking and ensuring that each paperboard can be smoothly separated and pushed. Two first limiting plates 31 are arranged on both sides of the vibration member 32 to limit the freedom of the pushing belt 5 in the width direction, which can prevent the pushing belt 5 from swinging left and right during rotation and vibration. This design ensures that the pushing belt 5 always runs along the predetermined width direction when pushing the paperboard, avoiding problems such as paperboard skewing, stacking disorder, etc. during the pushing process due to the position deviation of the pushing belt 5, further improving the accuracy and stability of the paperboard pushing, and ensuring the smooth and orderly of the feeding process. The vibration member 32, the first limiting plate 31 and the bearing frame 3 form an organic whole structure, and they cooperate with each other, which not only can realize effective vibration and accurate positioning of the pushing belt 5, but also can enhance the stability of the whole bearing frame 3 system. In the long-term and frequent feeding process, this stable structure helps to reduce the wear and failure probability of the components, improve the service life and reliability of the equipment, and thus ensure the continuous and efficient operation of the top and bottom cover paperboard feeding mechanism.

[0051] In this embodiment, the second limiting plate 9 has a planar portion 91 for limiting the paperboard and an arcuate portion 92 for guiding the paperboard into the planar portion 91, and the planar portion 91 is located above the arcuate portion 92.

[0052] In actual use, the arc surface part 92 of the second limiting plate 9 can play a good guiding role. When the paperboard begins to enter the limiting area, the arc surface part 92 can smoothly receive the paperboard and guide the paperboard to gradually enter the accurate limiting position of the plane part 91. Compared with directly using a plane for limiting, the arc surface part 92 effectively avoids the situation that the paperboard may be jammed or collided due to sudden contact with the plane, so that the paperboard can more naturally and smoothly enter the appropriate limiting state, ensuring that the feeding process can be smoothly started. The plane part 91 located above the arc surface part 92 bears the important function of accurately limiting the paperboard. After the arc surface part 92 guides the paperboard to smoothly reach the plane part 91, the plane part 91 can stably limit the paperboard from the vertical direction of the pushing direction, ensuring that the paperboard will not deviate in the left and right directions in the subsequent pushing process, so that the paperboard can accurately move according to the established pushing route, further improving the accuracy and stability of the position of the paperboard in the entire feeding process. The arc design of the arc surface part 92 plays a certain buffering role when the paperboard enters. Compared with a relatively sharp shape such as a right angle, the impact force on the edge of the paperboard when it contacts the limiting plate can be reduced, and the probability of damage or deformation of the paperboard due to collision can be reduced. In this way, the paperboard supplied to the subsequent process can maintain good integrity, which helps to improve the quality of the top and bottom cover and avoids affecting the appearance and use performance of the final product due to the poor initial state of the paperboard. Through the cooperation of the arc surface part 92 and the plane part 91, the process of the paperboard entering the limiting and being pushed subsequently is more smooth and efficient, reducing the situation of feeding interruption or repeated adjustment due to poor paperboard entry and inaccurate limiting, so that the feeding mechanism can continuously and stably provide paperboards meeting the requirements for subsequent production links, thereby improving the overall working efficiency of the top and bottom cover paperboard feeding link and even the entire production process.

[0053] In the embodiment, the frame 2 is rotatably provided with two parallel rotating rollers 17, and a seventh driving device 18 is configured to drive the two rotating rollers 17 to rotate. The two rotating rollers 17 are arranged at the end of the feeding belt 11 and are respectively arranged on the upper and lower sides of the paperboard conveyed by the feeding belt 11. The two rotating rollers 17 are configured to assist the feeding belt 11 to convey the paperboard to the next process.

[0054] In actual use, two parallel rotating rollers 17 are arranged at the end of the feeding belt 11, and are respectively located on the upper and lower sides of the conveyed paperboard. When the feeding belt 11 conveys the paperboard to this position, the rotation of the rotating rollers 17 can apply additional force to the paperboard. Through the cooperation with the feeding belt 11, the paperboard is further pushed forward to move, the power of the entire conveying system is enhanced, and the situation that the paperboard is insufficient in power, slow in conveying or even stagnant when entering the next process is effectively avoided, so that the paperboard can be smoothly and efficiently transferred to the next process. The two rotating rollers 17 are respectively located on the upper and lower sides of the paperboard, can limit the paperboard from the vertical direction, assist in conveying while ensuring that the paperboard moves along the accurate path in the horizontal direction, and prevent the paperboard from jumping up and down or deviating left and right at the end of the conveying. In this way, the paperboard can be accurately conveyed to the designated position of the next process, the accuracy of the feeding is improved, and the subsequent process can be smoothly carried out according to the standard process. The rotating rollers 17 share part of the friction and supporting pressure between the paperboard and the feeding belt 11, especially in the stage when the paperboard is about to leave the feeding belt 11, which can reduce the stress on the end of the feeding belt 11, reduce the probability of wear and damage of the feeding belt 11 due to long-term bearing of large pressure and friction, and prolong the service life of the feeding belt 11. At the same time, it can also reduce the damage to the paperboard caused by excessive pressure and other factors, and ensure that the appearance and quality of the paperboard conveyed to the next process are not affected. The auxiliary conveying function of the rotating rollers 17 makes the connection between the feeding belt 11 and the next process more closely and smoothly, avoiding the situation that manual intervention and adjustment are needed due to interruption of conveying or incoordination of connection. This seamless connection helps to maintain the continuity of the entire production process, reduces the production downtime caused by material conveying problems, and improves the overall production efficiency. Since the rotating rollers 17 can ensure that the paperboard is stable in position and in good condition during conveying, the paperboard can enter the next process in a required form and position, avoiding the quality defects of subsequent products caused by problems in the conveying link, and helping to ensure the quality stability of the top and bottom cover products and improve the overall quality of the products.

[0055] In the embodiment, the top and bottom cover paperboard belt feeding mechanism further comprises a base 1, an eighth driving device 19 arranged on the base 1, and a sliding seat 20 arranged on an external mechanism. The rack 2 is reciprocatingly arranged on the base 1 and is in sliding connection with the sliding seat 20. The eighth driving device 19 drives the rack 2 to reciprocate.

[0056] In actual use, the gantry 2 is driven to reciprocate on the base 1 by the eighth driving device 19, and the gantry 2 is slidably connected with the sliding seat 20 on the external mechanism, so that the position of the entire feeding mechanism in the plane can be flexibly adjusted. According to the specific layout of the subsequent different processes and actual production needs, the feeding position can be conveniently changed, so that the paperboard can be accurately conveyed to the corresponding processing position, whether it is to connect different top and bottom cover assembly equipment or to adapt to the layout requirements of different production lines, it can better meet the requirements and enhance the adaptability of the entire feeding system to different production scenes. In the production process, as the product process is improved or the production task is adjusted, the requirements of the subsequent processes for the paperboard feeding position may change. The design allows the gantry 2 to move flexibly, which can ensure that the feeding mechanism always connects well with the next process, avoids the situation that the material conveying route is unreasonable due to fixed position feeding, and needs to be additionally transported, etc., so that the entire top and bottom cover production process is more smooth and efficient, and reduces the problems of production stagnation or low efficiency caused by unreasonable feeding position. The feeding mechanism with the movable gantry 2 can be used in various top and bottom cover production workshop environments and different production line configurations, and does not need to be redesigned and customized for different space layouts and production processes, which reduces the cost investment of enterprises in equipment selection and layout, and improves the overall versatility and economy of the equipment.

[0057] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range can be changed, and the content of the specification should not be understood as limiting the present application.
