DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments is not a limitation of the utility model.

[0024] Please refer to Figs. 1 to 4As shown, the paper holder ring cutting machine comprises a rack 1, a cutter assembly 2 rotatably arranged on the rack 1, a power component for driving the cutter assembly 2 to rotate, a pickup component 3 reciprocally arranged on the rack 1 and rotatably arranged relative to the rack 1, a driving unit for driving the pickup component 3 to rotate, and a driving assembly 4 for driving the pickup component 3 to reciprocate, the pickup component 3 is used for picking up the external paper holder, and the driving assembly 4 drives the pickup component 3 to approach or move away from the cutter assembly 2 to realize the cutting of the edge of the paper holder.

[0025] In actual use, the pickup component 3 can rotate and reciprocate relative to the rack 1. This design enables the pickup component 3 to accurately control its approach or movement away from the cutter assembly 2 after picking up the paper holder through the driving assembly 4. For paper holder edge cutting, accurate positioning can ensure that the cutter cuts the edge of the paper holder along the predetermined trajectory, reducing problems such as irregular edge cutting or excessive or insufficient cutting, effectively improving product quality and consistency. The cutter assembly 2 is driven to rotate for cutting by the power component. Stable power supply ensures the uniformity of the cutter rotation speed, and when it contacts the accurately positioned paper holder, it can work at a stable cutting speed. This helps to avoid defects such as paper holder edge tearing and burr caused by uneven cutting speed, making the paper holder edge cutting surface smoother and flatter.

[0026] The pickup component 3 can automatically pick up the external paper holder, and under the synergistic action of the driving assembly 4 and the driving unit, it can automatically complete the action of approaching the cutter assembly 2 for cutting and subsequent actions. This automated operation process greatly reduces the manual intervention link and reduces labor costs.

[0027] Since the power component can continuously and stably provide power to the cutter assembly 2, the pickup component 3 can also continuously pick up and transport the paper holder for cutting. As long as the equipment is running normally and there is enough supply of paper holders, the ring cutting machine can continuously perform paper holder edge cutting operations. This helps to improve the coherence of the entire production process, reduce idle time, and further improve production efficiency. The reciprocating and rotating design of the pickup component 3 and the flexible control of its position by the driving assembly 4 enable the ring cutting machine to adapt to paper holders of different sizes. Whether it is a small paper holder for delicate small product packaging or a large paper holder for large mechanical component packaging, as long as the movement parameters of the pickup component 3 and the cutting range of the cutter assembly 2 are adjusted, paper holders of various specifications and sizes can be edge cut.

[0028] Specifically, the cutter assembly 2 has a cutting tool 21 rotatably arranged on the rack 1 and a cutting motor 22 for driving the cutting tool 21 to rotate.

[0029] In actual use, the cutting motor 22 serves as a power source for driving the cutting tool 21 to rotate, and can provide stable and continuous power output for the cutting tool 21. During the cutting process of the paper holder, stable power can ensure that the cutting tool 21 maintains a uniform rotational speed, so that the cutting action is smooth and continuous, avoiding the situation that the cutting speed is fast or slow due to unstable power. In this way, when cutting the edge of the paper holder, the cutting can be more accurately performed according to the set trajectory, effectively reducing the quality problems such as uneven cutting, notching or rough cutting of the edge of the paper holder, and improving the overall quality and yield of the paper holder cutting.

[0030] The cutting motor 22 has relatively high power output capability, and can drive the cutting tool 21 to rotate at a suitable high speed, thereby speeding up the cutting speed of the cutting tool 21 on the edge of the paper holder. Compared with manual or other cutting methods with insufficient power, this design of relying on motor to drive the tool to rotate at high speed greatly improves the working efficiency of the paper holder cutting, and more paper holders can be processed in unit time, meeting the needs of large-scale production.

[0031] Specifically, the support plate 11 for carrying the cutting tool assembly 2 is slidably arranged on the frame 1, and the push tool assembly 5 is arranged for driving the support plate 11 to slide. The power member is arranged on the support plate 11, and the push tool assembly 5 drives the cutting tool assembly 2 to slide to the preset cutting position through the support plate 11, and then the driving assembly 4 drives the pickup member 3 to cooperate with the fixed cutting tool assembly 2 to cut the edge of the paper holder mounted on the pickup member 3.

[0032] In actual use, before work, the push tool assembly 5 is specially responsible for sliding the cutting tool assembly 2 to the preset cutting position accurately, which provides an accurate starting position for the subsequent cutting work. Once the preset position is reached, the cutting tool assembly 2 is fixed and does not move, avoiding errors caused by the change of the position of the cutting tool assembly 2 during the cutting process, greatly improving the accuracy of the cutting of the edge of the paper holder, and helping to produce high-quality and uniform-size paper holder products.

[0033] The fixed characteristic of the cutting tool assembly 2 during work makes the entire cutting process more stable during cutting. When the driving assembly 4 drives the pickup member 3 to cut the paper holder, the fixed cutting tool assembly 2 will not be disturbed by additional shaking or displacement, ensuring stable application of cutting force, so that the cutting effect of the edge of the paper holder is more neat and smooth, reducing the phenomenon of rough edges, sawteeth and other adverse phenomena caused by shaking of the cutting tool, and improving the yield of the product.

[0034] The pusher assembly 5 only adjusts the position of the cutter assembly 2 before work, and then the cutter assembly 2 is fixed. This working mode simplifies the control logic of the equipment. Compared with the case where the cutter assembly 2 needs to be continuously adjusted during cutting, this design only needs to accurately control the action of the pusher assembly 5 at the starting stage, and then only needs to focus on the driving control of the pickup 3 by the driving assembly 4, which reduces the complexity of the control system, improves the stability and reliability of the equipment operation, and is also convenient for the operator to debug and maintain the equipment.

[0035] Specifically, the cutting tool 21 is a disc cutter, and the outer edge blade of the disc cutter is used to cut the paper tray.

[0036] In actual use, the outer edge blade of the disc cutter is continuous and annular in structure. When it rotates at high speed under the drive of the cutting motor 22 to cut the paper tray, it can cut into the paper tray and continuously act along the cutting track in a relatively uniform stress state. This uniform cutting force makes the cut edge of the paper tray smooth and prevents unevenness and obvious fluctuations. It can effectively reduce the burrs and burrs on the cutting surface, make the cut edge of the paper tray smooth, and improve the appearance quality of the paper tray, which meets the requirements of packaging and other application scenarios for the appearance of the paper tray.

[0037] The outer edge blade of the disc cutter has a clear cutting line, and its cutting track is easier to control accurately than some irregularly shaped or irregularly shaped blades. When cutting the edge of the paper tray in cooperation with the pickup 3 and the pusher assembly 5, the operator can more accurately control the rotation, translation and other actions of the disc cutter to make the blade cut along the predetermined edge of the paper tray, thereby ensuring the cutting accuracy, reducing the cutting error, and ensuring that the shape and size of the cut paper tray meet the design requirements.

[0038] The structural characteristics of the disc cutter enable it to maintain good stability when rotating and withstand high speed. Under the power provided by the cutting motor 22, the disc cutter can rotate at high speed and quickly cut the edge of the paper tray. Compared with some traditional cutters with blade shapes that are not conducive to high-speed motion, the disc cutter can greatly improve the cutting speed, shorten the cutting time of a single paper tray, and thus process more paper trays in a unit of time, improve the working efficiency of the entire paper tray cutting machine, and meet the needs of large-scale production. Since the outer edge blade of the disc cutter is annular and there is no obvious start and end point of cutting (cutting can be performed during continuous rotation), it is not necessary to frequently adjust the initial cutting position when cutting the continuous edge of the paper tray as some cutters with obvious blade heads and blade tails do. As long as the rotation of the disc cutter and the relative position movement between the disc cutter and the paper tray are controlled, the cutting can be continuously completed along the edge of the paper tray, reducing the stopping and repositioning time during cutting, further improving the cutting efficiency, and making the entire cutting process smoother and more efficient.

[0039] Specifically, the rack 1 is provided with a bearing frame 12 for mounting the driving assembly 4, the bearing frame 12 is slidably provided with a bearing plate 13, the bearing plate 13 is rotatably provided with a transmission assembly 6, the output end of the transmission assembly 6 is connected with the pickup 3, and the driving unit drives the transmission assembly 6 to drive the pickup 3 to rotate.

[0040] In actual use, the driving assembly 4 is installed by setting the bearing frame 12 on the rack 1, which provides a stable and reliable installation foundation for the entire transmission and pickup-related structure. As a component fixed on the rack 1, the bearing frame 12 can withstand the weight of subsequent components and various forces generated during operation, ensuring that the entire structure will not be affected by unstable factors such as shaking and displacement during work, thereby improving the precision and quality of the paper tray ring cutting process.

[0041] The bearing plate 13 is slidably arranged on the bearing frame 12, and this sliding connection mode makes the bearing plate 13 be guided and constrained by the bearing frame 12 during movement, and can smoothly slide along the predetermined direction. When the driving assembly 4 drives the bearing plate 13 to move, the smoothness of sliding can avoid abnormal situations such as deflection and jamming of the bearing plate 13, thereby ensuring that the transmission assembly 6 rotatably arranged on the bearing plate 13 and the pickup 3 connected therewith can also work in a stable state. For example, when picking up the paper tray and moving it to the vicinity of the cutter assembly 2, it can ensure that the paper tray accurately and smoothly reaches the cutting position, reducing the positioning error of the paper tray caused by unstable movement.

[0042] The transmission assembly 6 is rotatably arranged on the bearing plate 13, and the output end thereof is connected with the pickup 3. This design enables the driving unit to accurately transmit power to the pickup 3 when driving the transmission assembly 6, thereby achieving precise control of the rotation angle and rotation speed of the pickup 3. During the paper tray ring cutting process, accurate control of the rotation of the pickup 3 is crucial to ensure the uniformity and integrity of the paper tray edge cutting. For example, the paper tray can be rotated at a uniform speed according to the set angle, allowing the cutter assembly 2 to accurately cut each part of the paper tray edge, avoiding problems such as incomplete cutting or excessive cutting in some areas.

[0043] Since this structural system composed of the bearing plate 13, the transmission assembly 6, and the pickup 3 has good flexibility and adjustability, the equipment can easily adapt to different specifications of paper trays. Whether it is a small paper tray that requires small amplitude rotation and precise positioning, or a large paper tray that requires higher stability in bearing and rotation, the equipment can effectively pick up, rotate, and cut different paper trays by appropriately adjusting the sliding range of the bearing plate 13, the transmission parameters of the transmission assembly 6, etc., thereby improving the versatility of the equipment and enabling it to be widely used in various paper tray production scenarios.

[0044] Specifically, the driving assembly 4 has a driving motor 41 arranged on the rack 1, two transmission wheels 42 arranged in parallel on the rack 1, an output shaft of the driving motor 41 connected with one of the transmission wheels 42, and a transmission belt 43 arranged around the outer periphery of the two transmission wheels 42 and connected with the pickup 3. The driving motor 41 drives the transmission wheels 42 to rotate the transmission belt 43, and the pickup 3 reciprocates on the rack 1 by the positive and negative rotation of the transmission belt 43.

[0045] In actual use, the pickup 3 reciprocates by the connection of the output shaft of the driving motor 41 with the transmission wheel 42 and the transmission of the transmission belt 43. This transmission mode can realize relatively accurate motion control. The rotation speed and direction of the driving motor 41 can be accurately adjusted by an electrical control system, so as to accurately control the rotation of the transmission wheel 42 and the motion state of the transmission belt 43. Since the transmission belt 43 is connected with the pickup 3, the pickup 3 can accurately reciprocate on the rack 1 at a set speed and stroke, ensuring that the pickup 3 can accurately approach or move away from the cutter assembly 2, thereby ensuring the accuracy of the edge cutting of the paper tray and avoiding problems such as cutting the paper tray in the wrong part or incomplete edge cutting due to deviation of the motion position.

[0046] The two transmission wheels 42 arranged in parallel on the rack 1 and the transmission belt 43 arranged around the outer periphery thereof provide stable motion guidance for the pickup 3. The rotation of the transmission belt 43 on the transmission wheel 42 is along a fixed track, which makes the pickup 3 connected therewith reciprocate on the rack 1 along a preset and stable straight track, without unstable motion states such as random deviation and shaking. In the process of picking up the paper tray and conveying it to the cutter assembly 2 for cutting, the stable motion track helps to maintain the correct position of the paper tray, facilitating the cutter assembly 2 to perform high-quality cutting operation on the edge of the paper tray and ensuring the flatness and consistency of the cutting surface.

[0047] Specifically, the driving unit is a rotary motor 61 arranged on the carrier plate 13, and the transmission assembly 6 has a rotating shaft 62 rotatably arranged on the carrier plate 13. The rotary motor 61 acts on one end of the rotating shaft 62 via wheel transmission, belt transmission or chain transmission to drive the rotating shaft 62 to rotate, and the other end of the rotating shaft 62 is connected with the pickup 3.

[0048] In actual use, the rotary motor 61 acts on the rotating shaft 62 through wheel transmission, belt transmission or chain transmission, and then drives the pickup 3 to rotate. This transmission link can realize more accurate control of the rotating angle of the pickup 3. The rotary motor 61 itself can accurately adjust the rotating speed and direction, and the wheel, belt or chain transmission mode can accurately transmit the power of the motor to the rotating shaft 62 under reasonable design, so that the rotating shaft 62 rotates according to the set angle, and then drives the pickup 3 to accurately rotate by the corresponding angle. When the paper tray is ring-cut, accurate angle control can ensure that each part of the paper tray edge can be uniformly cut, avoiding problems such as part of the edge not being cut or repeated cutting due to deviation of the rotating angle, and ensuring the quality and precision of the paper tray cutting.

[0049] Gear transmission, belt transmission or chain transmission can provide relatively stable power transmission effect after reasonable tensioning, installation and other treatments. In the whole transmission process, the continuity of power transmission can be maintained, so that the rotating shaft 62 rotates smoothly and uniformly, and unstable conditions such as fast and slow or jamming do not occur. This is very important for the pickup 3 to drive the paper tray to rotate stably, which ensures that the paper tray can cooperate with the cutter assembly 2 in a stable state during the ring cutting of the paper tray, so that the cutter can cut along the edge of the paper tray smoothly, reducing quality defects such as uneven cutting and burr caused by unstable rotation of the paper tray.

[0050] Specifically, the output shaft of the rotary motor 61 is provided with a first wheel body 63, and the rotating shaft 62 is provided with a second wheel body 64, and the first wheel body 63 and the second wheel body 64 are in belt transmission cooperation.

[0051] In actual use, the belt transmission has good elasticity and flexibility, and can effectively buffer and absorb the vibration and impact that may occur during the operation of the rotary motor 61 in the process of transmitting power to the rotating shaft 62 through the first wheel body 63, the transmission belt 43 and the second wheel body 64. For example, when the motor starts or stops instantaneously, or when slight speed fluctuations occur during operation, the transmission belt 43 can rely on its elastic properties to avoid these vibrations and impacts being directly transmitted to the rotating shaft 62 and the pickup 3 connected thereto, thereby ensuring that the process of rotating the paper tray by the pickup 3 is more stable, reducing quality problems such as uneven cutting edge and jagged edge of the paper tray caused by vibration, and ensuring the quality of the ring cutting of the paper tray.

[0052] By reasonably selecting the diameter sizes of the first wheel body 63 and the second wheel body 64, the transmission ratio can be accurately set. This means that the rotation speed output by the rotary motor 61 can be accurately transmitted to the rotating shaft 62 according to a predetermined ratio, realizing accurate control of the rotation speed of the rotating shaft 62, and further accurately controlling the rotation speed of the pickup piece 3. In the paper holder ring cutting operation, different materials, thicknesses and sizes of the paper holder may require different rotation speeds to cooperate with the cutting knife assembly 2 to achieve the best cutting effect. By utilizing the characteristic of flexible adjustment of the transmission ratio of the belt transmission, the rotation speed of the pickup piece 3 can be accurately adjusted according to the actual requirements, ensuring that the paper holder edge is cut to the right place, neither too fast to cause rough cutting surface, nor too slow to affect production efficiency.

[0053] Specifically, the push knife assembly 5 has a guide shaft 51 slidingly matched with the support plate 11 arranged on the rack 1, and a screw rod 52 threadedly matched with the support plate 11. One end of the screw rod 52 is threadedly connected with the support plate 11, and the other end of the screw rod 52 is provided with a driver 53 for driving the screw rod 52 to rotate.

[0054] In actual use, the guide shaft 51 slidingly matches with the support plate 11 to provide accurate linear guidance for the sliding of the support plate 11. It ensures that the support plate 11 can only move linearly along the direction defined by the guide shaft 51 during movement, avoiding unstable conditions such as lateral deviation and shaking. When the cutting knife assembly 2 cuts the edge of the paper holder, this accurate guidance allows the cutting knife assembly 2 to approach or move away from the paper holder along the predetermined linear trajectory, ensuring the accuracy of the cutting position, making the paper holder edge cut neat and standard, and effectively preventing cutting errors caused by deviation of the tool movement trajectory, such as cutting deviation and cutting to the part of the paper holder that should not be cut.

[0055] The screw rod 52 is threadedly matched with the support plate 11 and is driven by the driver 53 to rotate, which realizes high-precision adjustment of the displacement of the support plate 11. The pitch of the screw rod 52 is fixed. When the driver 53 drives the screw rod 52 to rotate by a certain angle, the screw rod 52 will accurately move the support plate 11 by a corresponding distance along the guide shaft 51 according to its pitch characteristics. This accurate displacement adjustment capability enables the cutting knife assembly 2 to accurately adjust to the appropriate position according to the size, shape and specific cutting requirements of different paper holders, whether it is equidistantly segmented cutting of the edge of the paper holder or asymmetric position adjustment for a specific shape of the paper holder, it can be accurately realized, greatly improving the flexibility and accuracy of cutting.

[0056] In this embodiment, the driver 53 is a hand wheel connected with the screw rod 52.

[0057] In actual use, before work, the pusher assembly 5 is specially responsible for sliding the cutter assembly 2 to the preset cutting position accurately, which provides an accurate starting position for the subsequent cutting work. Once reaching the preset position, the cutter assembly 2 is fixed, avoiding errors caused by the change of the position of the cutter assembly 2 during cutting, greatly improving the accuracy of the edge cutting of the paper holder, and helping to produce high-quality, size-uniform paper holder products. When the driver 53 is a hand wheel connected with the lead screw 52, the operator can slowly and finely rotate the hand wheel manually to fine-tune the position of the cutter assembly 2, further ensuring the accuracy of its reaching the preset position. Compared with some automatic driving methods, the hand wheel is more controllable in fine-tuning. Since the hand wheel itself has a certain mechanical self-locking property, it can better maintain the fixed state of the cutter assembly 2 and prevent accidental displacement during cutting.

[0058] Specifically, the rack 1 is provided with a bearing plate 7, the pickup piece 3 is located above the bearing plate 7, and the cutter assembly 2 is located below the bearing plate 7. The bearing plate 7 is provided with a through hole, and the cutting part of the cutter assembly 2 protrudes above the bearing plate 7 through the through hole to cut the paper holder.

[0059] In actual use, the bearing plate 7 serves as a relatively fixed and flat structure to provide a stable reference plane for the cutting work of the cutter assembly 2. The cutting part of the cutter assembly 2 protrudes up through the through hole, and is positioned in height with reference to the bearing plate 7 when cutting the paper holder. This helps to ensure that the relative position of the cutter and the paper holder remains consistent during each cutting, avoiding problems such as uneven cutting of the paper holder edge and varying depth of the cut due to unstable cutting height, thereby improving the accuracy of the cutting and making the cut paper holder edge more uniform and standardized, meeting the quality requirements.

[0060] The presence of the through hole on the bearing plate 7 allows the cutting part of the cutter assembly 2 to flexibly adjust its protruding height within a reasonable range according to the different thicknesses of the paper holder, to adapt to the cutting needs of paper holders of different thicknesses. By adjusting the up-and-down position of the cutter assembly 2 relative to the bearing plate 7, the cutting part can accurately contact and cut the edge of the paper holder, without the need for large-scale modification of the structure of the entire equipment, improving the versatility of the equipment for different specifications of paper holders, and making it widely applicable to various paper holder production scenarios to meet diverse market demands.

[0061] The pickup piece 3 is arranged above the bearing flat plate 7, and the cutter assembly 2 is arranged below the bearing flat plate 7, so that the three-dimensional space of the rack 1 is fully utilized, and the overall structure of the equipment is more compact and reasonable. Compared with the design of placing the two in a disorderly manner or simply laying them on the same plane, the layered space layout can clearly divide the areas of different functional components in the limited range of the rack 1, avoid unnecessary space interference between the components, provide convenience for the assembly, debugging and subsequent maintenance of the equipment, and facilitate the operator to better observe and control the paper tray picking and cutting processes.

[0062] In the embodiment, the rack 1 is provided with a controller 8 for controlling the operation of the paper tray ring cutter, and the controller 8 is provided with a plurality of buttons 81.

[0063] In actual use, the controller 8 is provided with a plurality of buttons 81, which provides an intuitive and convenient operation interface for the operator. Different buttons 81 correspond to different functional operations of the paper tray ring cutter, such as starting, stopping, cutting speed adjustment, pickup piece 3 movement control, etc. The operator does not need complex professional knowledge or remember complicated operation instructions, but only needs to press the corresponding button 81 according to the mark or simple operation instruction on the button 81, so as to quickly realize the control of the corresponding function of the equipment, greatly simplify the operation process, reduce the operation threshold, and make the use of the equipment more convenient and fast. Even new employees with relatively insufficient experience can quickly operate.

[0064] The existence of the plurality of buttons 81 enables the operator to quickly switch between different functions. For example, when the paper tray needs to be picked and positioned first, the corresponding pickup piece 3 control button 81 can be pressed; after the paper tray is positioned, the cutter assembly 2 start button 81 can be quickly pressed to perform cutting work; if the cutting speed is not suitable, the speed adjustment button 81 can be immediately pressed to adjust the cutting speed. Such quick function switching capability helps to optimize the entire paper tray ring cutting work process, improve work efficiency, reduce time waste caused by inconvenient operation, and makes the equipment more flexible to cope with different production demands and working condition changes.

[0065] The above is only a preferred embodiment of the present application, and for ordinary skilled in the art, according to the idea of the present application, the specific implementation mode and application range can be changed, and the content of the specification should not be understood as limiting the present application.
