Description
Technical Field
[0001] This utility model relates to the field of label material conveying technology, specifically a label printing and feeding machine. Background Technology
[0002] In the label printing industry, the loading machine, as a core piece of equipment at the front end of the printing production line, undertakes the crucial task of accurately transferring label materials (such as paper labels and plastic label substrates) from the storage area to subsequent processes such as printing presses and die-cutting machines. However, existing label printing loading machines have many technical limitations in practical applications, making it difficult to meet the "high efficiency, flexibility, and automation" requirements of modern printing production lines. Specific problems are as follows:
[0003] On the one hand, the conveying direction is singular, resulting in poor production flexibility. Traditional feeding machines mostly adopt a structure of "single conveyor belt + fixed guide plate," which can only realize the unidirectional linear conveying of label materials. It is impossible to adjust the conveying direction according to the layout of different printing processes (such as printing machines and die-cutting machines being distributed at 90°, or multiple printing machines being arranged in parallel). If it is necessary to change the material flow direction, manual handling of materials or additional turning conveying equipment are required. This not only increases labor costs (1-2 people are required to handle turning and handling on a single production line), but also causes material misalignment and damage due to human operation errors, reducing the printing pass rate (the pass rate is usually only 85%-90%). At the same time, the addition of extra equipment will also occupy workshop space and increase production costs.
[0004] On the other hand, the feeding accuracy is low and the degree of automation is insufficient. Existing feeding machines lack precise material positioning and sensing control. During the conveying process, the material is prone to deviation due to conveyor belt vibration and speed fluctuations, resulting in positional deviation when entering the printing press. This requires real-time manual adjustment, affecting printing efficiency (the hourly processing capacity is only 1000-1500 pieces). In addition, the start-up, shutdown, and steering of traditional feeding machines mostly rely on manual control, which cannot be linked with the operating rhythm of subsequent printing equipment. When the temporary storage station of the printing press is full, the feeding machine continues to feed, which can easily cause material accumulation and blockage, requiring machine shutdown for cleaning, further reducing production continuity.
[0005] Furthermore, the conveying stability is poor, and materials are easily damaged. Traditional feeders often use rigid friction guides (such as metal guide plates directly contacting the material). Label materials (especially thin paper labels) are easily scratched by the guide plates during the turning process, resulting in edge damage, or the material may be stretched and deformed due to excessive frictional resistance. At the same time, the conveyor belt lacks limiting support, and is prone to slack and deviation during high-speed conveying, resulting in unstable material conveying trajectory and further affecting the feeding accuracy. These defects result in existing feeders having significant deficiencies in the coordination of "multi-directional conveying - precise positioning - automated linkage," making it difficult to adapt to the multi-process, high-paced production needs of modern label printing production lines. Therefore, there is an urgent need for a label printing feeder that combines multi-directional conveying function, high-precision positioning, and automated control. Utility Model Content
[0006] The purpose of this utility model is to provide a label printing feeding machine that solves the technical problems of low feeding efficiency, single conveying direction, and inability to achieve continuous multi-directional automated conveying in the traditional label material printing process, thereby enhancing production flexibility and achieving effective and continuous multi-directional conveying of label materials.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a label printing and feeding machine, comprising a conveying and feeding frame, a rotation direction adjustment unit, and a sensing cylinder pushing unit, wherein a support pad is fixedly installed on the bottom outer wall of the conveying and feeding frame; the rotation direction adjustment unit is disposed inside the conveying and feeding frame; and the sensing cylinder pushing unit is disposed on the outer walls of both sides of the conveying and feeding frame.
[0008] Preferably, the rotation direction adjustment unit specifically includes: a first conveyor belt, disposed inside the conveyor feeding rack; a second conveyor belt, disposed inside the conveyor feeding rack; a third conveyor belt, disposed inside the conveyor feeding rack; a fourth conveyor belt, disposed inside the conveyor feeding rack; a fifth conveyor belt, disposed inside the conveyor feeding rack; and a motor fixing bracket, fixedly installed on the bottom outer wall of the conveyor feeding rack.
[0009] Preferably, conveyor belt two and conveyor belt three are respectively arranged on both sides of conveyor belt one, conveyor belt four is arranged on one side of conveyor belt three, and conveyor belt five is arranged between conveyor belt four and conveyor belt two. A drive motor is fixedly installed inside the motor fixing frame. A connecting rod is fixedly connected to the output end of the drive motor. The other end of the connecting rod movably passes through the bottom outer wall of the conveyor feeding frame and extends into the interior of the conveyor feeding frame.
[0010] Preferably, a rotating circular plate is fixedly connected to the other end of the connecting rod, and a steering limit frame is fixedly installed on the top of the rotating circular plate. The inner circumference of the steering limit frame is provided with a circular groove.
[0011] Preferably, a shaft is fixedly installed on the inner wall of the circular groove, and a rotating roller is movably sleeved on the outer wall of the shaft. A fixed top plate is provided on the top of the steering limit frame, and shaft holes are equidistantly opened on the fixed top plate. The shaft is adapted to the shaft holes, and the fixed top plate is fixedly installed on the top outer wall of the steering limit frame through the shaft holes.
[0012] A steering limit frame is installed, with a fixed top plate design on the top of the steering limit frame to provide rigid support for the conveyor belt, preventing it from twisting or loosening during high-speed transmission or turning. At the same time, the rolling friction characteristics of the rotating roller in the circular groove significantly reduce the friction between the conveyor belt and the limit frame, reducing wear and extending the equipment life. The rotation design of the steering limit frame is in sync with conveyor belt one, enabling continuous feeding of parts and steering adjustment to conveyor belt two or three.
[0013] Preferably, the induction cylinder pushing part specifically includes: a rectangular fixing frame one, which is connected to one side of the outer wall of the conveying and feeding frame; a rectangular fixing frame two, which is connected to the other side of the outer wall of the conveying and feeding frame; and a sensor positioning sleeve, which is fixedly installed on both sides of the outer wall of the conveying and feeding frame.
[0014] Preferably, a cylinder mounting bracket is fixedly installed on one outer wall of both the first rectangular mounting bracket and the second rectangular mounting bracket. A rectangular sliding groove is opened inside both the first rectangular mounting bracket and the second rectangular mounting bracket. Telescopic cylinder one and telescopic cylinder two are fixedly installed on the inner wall of the cylinder mounting bracket respectively. The telescopic ends of telescopic cylinder one and telescopic cylinder two respectively movably penetrate through the outer wall of the first rectangular mounting bracket and the second rectangular mounting bracket and extend into the interior of the rectangular sliding groove.
[0015] The system is equipped with telescopic cylinder one and telescopic cylinder two. When the label material moves on the conveyor rack, telescopic cylinder one and telescopic cylinder two will extend and retract as needed, pushing the rectangular push block to slide in the rectangular chute. This design allows the mechanism to flexibly adjust the position of the label material, ensuring that it can be accurately conveyed to the next process.
[0016] Preferably, the telescopic ends of telescopic cylinder one and telescopic cylinder two are fixedly connected to rectangular push blocks. The rectangular push blocks are slidably installed inside the rectangular slide groove. Sensor one and sensor two are fixedly installed inside the sensor positioning sleeve. The sensing ends of sensor one and sensor two pass through the outer wall of the conveyor feeding rack through the sensor positioning sleeve and extend into the interior of the conveyor feeding rack.
[0017] Sensor 1 and Sensor 2 are installed, each fixedly mounted inside a sensor positioning sleeve. Their sensing ends can move through the outer wall of the conveyor rack and extend into its interior. These sensors can monitor the position and status of the label materials in real time, ensuring the mechanism can accurately respond and adjust the conveying direction or speed.
[0018] This utility model provides a label printing and feeding machine. It has the following beneficial effects:
[0019] 1. This label printing and feeding machine, through its "rotation direction adjustment unit + multiple conveyor belts working together" design, achieves flexible multi-directional conveying of label materials, adapting to different workshop layouts and significantly improving production flexibility. In terms of conveying path design, the rotation direction adjustment unit adopts a matrix layout of "one main conveyor belt + one branch conveyor belt": Conveyor belt one serves as the main conveying channel, responsible for receiving initial materials; conveyor belts two and three are symmetrically distributed on both sides of conveyor belt one, enabling 90° turning conveying; conveyor belt four connects to conveyor belt three for longitudinal conveying; conveyor belt five connects conveyor belt two and conveyor belt four, forming a closed-loop conveying path, allowing for flexible switching of material flow direction according to printing process requirements (such as different arrangements of "printing-die-cutting-quality inspection").
[0020] 2. In terms of steering control, the drive motor drives the rotating disc and steering limit frame to rotate via a connecting rod. The rotating rollers on the inner wall of the steering limit frame are movably sleeved through a shaft, which converts the sliding friction between the material and the limit frame into rolling friction, reducing frictional resistance by more than 50% and preventing damage to thin labels. At the same time, the fixed top plate is fixed to the shaft through the shaft hole, providing rigid support for the steering limit frame and preventing deformation of the frame during high-speed steering, ensuring a stable material conveying trajectory. This design allows the feeder to adapt to various process layouts such as "L-shaped" and "U-shaped" without the need for additional steering equipment, reducing labor costs per production line by 50% and material loss rate to below 3%.
[0021] 3. This feeding machine, through its "induction cylinder push unit + dual sensor linkage" design, achieves precise positioning and automated conveying of labeled materials, significantly improving feeding accuracy and production efficiency. In terms of positioning and pushing, the induction cylinder push unit adopts a "dual cylinder + rectangular chute" structure: rectangular fixing frame one and rectangular fixing frame two correspond to the discharge ends of conveyor belt two and conveyor belt three, respectively. The internal rectangular chute provides guidance for the rectangular push block, ensuring the linearity of the push block's movement trajectory; the telescopic ends of telescopic cylinder one and telescopic cylinder two are fixed to the rectangular push block, allowing for precise material pushing according to the material's position (push block positioning error ≤ 0.5mm), preventing material deviation after turning.
[0022] 4. In terms of automation control, Sensor 1 and Sensor 2 within the sensor positioning sleeve monitor the material position on Conveyor 2 and Conveyor 3 in real time. When the sensors detect that the material has reached the designated position, they immediately trigger the corresponding telescopic cylinder to achieve "material arrival - automatic push" linkage control. Simultaneously, the sensor signals can be linked with the control system of subsequent printing equipment. When the printing press's temporary storage station is full, the sensor feeds back a signal to the drive motor, pausing the corresponding conveyor belt to prevent material accumulation. This design improves feeding accuracy to over 99%, increases hourly throughput to 3000-3500 pieces, and doubles production efficiency compared to traditional equipment. Furthermore, it eliminates the need for real-time manual monitoring, achieving full automation of the feeding process. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0030] Example 1:
[0031] A preferred embodiment of the label printing feeder provided by this utility model is, for example... Figures 1-4 As shown: A label printing and feeding machine includes a conveyor feeding frame 1, a rotation direction adjustment unit 3, and a sensor cylinder pushing unit 4. A support pad 2 is fixedly installed on the bottom outer wall of the conveyor feeding frame 1; the rotation direction adjustment unit 3 is located inside the conveyor feeding frame 1; and the sensor cylinder pushing unit 4 is located on both outer walls of the conveyor feeding frame 1.
[0032] The rotation direction adjustment unit 3 specifically includes: conveyor belt one 311, which is installed inside the conveyor loading rack 1; conveyor belt two 312, which is installed inside the conveyor loading rack 1; conveyor belt three 313, which is installed inside the conveyor loading rack 1; conveyor belt four 314, which is installed inside the conveyor loading rack 1; conveyor belt five 315, which is installed inside the conveyor loading rack 1; and motor fixing bracket 316, which is fixedly installed on the bottom outer wall of the conveyor loading rack 1.
[0033] Conveyor belt 2 312 and conveyor belt 313 are respectively located on both sides of conveyor belt 1 311, conveyor belt 4 314 is located on one side of conveyor belt 313, and conveyor belt 5 315 is located between conveyor belt 4 314 and conveyor belt 2 312. A drive motor 317 is fixedly installed inside the motor mounting bracket 316. A connecting rod is fixedly connected to the output end of the drive motor 317. The other end of the connecting rod movably passes through the bottom outer wall of the conveyor loading rack 1 and extends into the interior of the conveyor loading rack 1.
[0034] The other end of the connecting rod is fixedly connected to a rotating circular plate 318. A steering limit frame 319 is fixedly installed on the top of the rotating circular plate 318. A circular groove 3113 is opened on the inner circumference of the steering limit frame 319.
[0035] A shaft 3112 is fixedly installed on the inner wall of the circular groove 3113, and a rotating roller 3111 is movably sleeved on the outer wall of the shaft 3112. A fixed top plate 3114 is provided on the top of the steering limit frame 319. Shaft holes are opened at equal intervals on the fixed top plate 3114. The shaft 3112 is adapted to the shaft holes. The fixed top plate 3114 is fixedly installed on the top outer wall of the steering limit frame 319 through the shaft holes.
[0036] In this embodiment, the label material is placed at the starting position of the conveyor loading rack 1, i.e., on conveyor belt 1 311. The drive motor 317 is started, and the steering limit frame 319 is rotated through the connecting rod and the rotating circular plate 318. According to the printing requirements of the label material, the label material can be conveyed to conveyor belt 2 312 or conveyor belt 313 by adjusting the angle of the steering limit frame 319. This allows the label material to be flexibly conveyed in multiple directions on the conveyor loading rack. This design meets the requirements for fast and accurate conveying of label material between different processes.
[0037] Example 2:
[0038] Please see Figures 1-4 Furthermore, based on Embodiment 1, the following is obtained: the sensing cylinder pushing part 4 specifically includes: a rectangular fixing frame 1 413, which is connected to one side of the outer wall of the conveying and feeding frame 1; a rectangular fixing frame 2 418, which is connected to the other side of the outer wall of the conveying and feeding frame 1; and a sensor positioning sleeve 415, which is fixedly installed on both sides of the outer wall of the conveying and feeding frame 1.
[0039] A cylinder mounting bracket 411 is fixedly installed on one outer wall of both rectangular mounting bracket 1 413 and rectangular mounting bracket 2 418. A rectangular sliding groove 414 is opened inside both rectangular mounting bracket 1 413 and rectangular mounting bracket 2 418. Telescopic cylinder 1 412 and telescopic cylinder 2 419 are fixedly installed on the inner wall of the cylinder mounting bracket 411 respectively. The telescopic ends of telescopic cylinder 1 412 and telescopic cylinder 2 419 respectively move through the outer wall of rectangular mounting bracket 1 413 and rectangular mounting bracket 2 418 and extend into the interior of the rectangular sliding groove 414.
[0040] Both telescopic cylinder 412 and telescopic cylinder 419 are fixedly connected to rectangular push blocks 416 at their telescopic ends. The rectangular push blocks 416 are slidably installed inside the rectangular slide groove 414. Sensor 417 and sensor 4111 are fixedly installed inside the sensor positioning sleeve 415 respectively. The sensing ends of sensor 417 and sensor 4111 move through the outer wall of the conveyor rack 1 through the sensor positioning sleeve 415 and extend into the interior of the conveyor rack 1.
[0041] In this embodiment, when the label material arrives on conveyor belt 2 312: sensor 1 417 detects the label material and triggers the extension / retraction of telescopic cylinder 1 412. Telescopic cylinder 1 412 pushes the label material from conveyor belt 2 312 onto conveyor belt 5 315 via rectangular pusher 416. The label material is then conveyed to conveyor belt 4 314 via conveyor belt 5 315, ready for the next printing step. When the label material arrives on conveyor belt 3 313: sensor 2 4111 detects the label material and triggers the extension / retraction of telescopic cylinder 2 419. Telescopic cylinder 2 419 pushes the label material from conveyor belt 3 313 onto conveyor belt 4 314 via rectangular pusher 416. This can push the label material to move on the conveyor rack according to a predetermined route and speed. This control helps improve the accuracy of the conveying and ensures that the label material can accurately reach the designated position. At the same time, the rapid response and efficient operation of the cylinder also improves the efficiency of the conveying.
[0042] Working principle: First, perform an initialization check on the equipment: confirm that the support pad 2 firmly supports the conveyor feeding rack 1 to avoid vibration during equipment operation; check that the power supply and air pressure connection of the drive motor 317, telescopic cylinder 1 412, and telescopic cylinder 2 419 are normal, and that the sensing ends of sensor 1 417 and sensor 2 4111 are not obstructed (the sensor positioning sleeve 415 ensures that the sensing end extends into the inside of the conveyor feeding rack 1 for accurate material monitoring).
[0043] After initialization, the label materials are neatly placed on the starting conveyor channel of the conveyor loading rack 1—conveyor belt 1 311. The drive motor 317 is started (the motor fixing frame 316 ensures stable operation of the motor and avoids vibration affecting the conveying). The output end of the drive motor 317 drives the rotating disc 318 to rotate through the connecting rod. The steering limit frame 319 on the top of the rotating disc 318 rotates synchronously with it. According to the needs of the subsequent printing process (if the material needs to be conveyed to the left printing machine, it turns 0°; if it needs to be conveyed to the right die-cutting machine, it turns 180°), the angle of the steering limit frame 319 is adjusted so that the material on conveyor belt 1 311 can be accurately guided to the target branch conveyor belt (conveyor belt 2 312 or conveyor belt 3 313).
[0044] Once the steering limit frame 319 is adjusted to the target angle, the conveyor belt 311 starts, driving the label material towards the steering limit frame 319. When the material contacts the rotating roller 3111 on the inner wall of the steering limit frame 319, the rotating roller 3111 rolls around the shaft 3112 (fixed in the circular groove 3113 of the steering limit frame 319), converting the sliding friction between the material and the limit frame into rolling friction, reducing material wear. At the same time, the fixed top plate 3114 at the top of the steering limit frame 319 is fixed to the shaft 3112 through the shaft hole, providing rigid support for the steering limit frame 319, preventing it from deforming due to material impact, and ensuring that the material turns along the preset trajectory.
[0045] If the material needs to be transferred to the left-side process (such as a printing machine), the steering limit frame 319 guides the material into conveyor belt two 312; if it needs to be transferred to the right-side process (such as a die-cutting machine), the material is guided into conveyor belt three 313; conveyor belt two 312 and conveyor belt three 313 start synchronously, and convey the material in the direction of the induction cylinder push unit 4. At this time, the fixed top plate 3114 still plays a limiting role on the edge of the conveyor belt to prevent the material from deviating.
[0046] When the material is conveyed to the end of conveyor belt 2 312, sensor 1 417 in sensor positioning sleeve 415 senses the material and immediately sends a signal to the control system, triggering the telescopic cylinder 1 412 on rectangular fixed frame 1 413 to move: the telescopic end of telescopic cylinder 1 412 pushes the rectangular push block 416 to slide along the rectangular slide groove 414 (the rectangular slide groove ensures that the push block moves in a straight line), avoiding pushing deviation, and accurately pushing the material from conveyor belt 2 312 into conveyor belt 5 315; conveyor belt 5 315 starts and conveys the material to conveyor belt 4 314, and conveyor belt 4 314 then conveys the material to the subsequent printing process (such as the printing machine feed port).
[0047] If the material is conveyed on conveyor belt 313, sensor 2 4111 in sensor positioning sleeve 415 will sense the material and trigger telescopic cylinder 2 419 on rectangular fixed frame 2 418 to move. Telescopic cylinder 2 419 will push the material directly into conveyor belt 414 through rectangular push block 416 to realize the convergence and conveying of materials from different paths.
[0048] Throughout the process, sensor 1 (417) and sensor 2 (4111) will also provide real-time feedback of material position signals to the control system of the subsequent printing equipment: if the temporary storage station of the printing machine is full, the control system will pause the operation of the corresponding conveyor belt (such as conveyor belt 2 or 3) and stop the telescopic cylinder action, and restart it after the printing machine station is idle to avoid material accumulation; if the sensor does not detect material (such as when the material is exhausted), it will send a warning signal to remind the operator to replenish the material to ensure continuous production.
[0049] After a batch of label materials has been loaded, turn off the power and air pressure of the drive motor 317, telescopic cylinder 1 412, and telescopic cylinder 2 419; clean the dust and residual materials on the surface of the conveyor loading rack 1 and each conveyor belt; check whether the rotating roller 3111 of the steering limit frame 319 is stuck (if stuck, add lubricant); check whether the sensing ends of sensor 1 417 and sensor 2 4111 are clean (if there are stains, wipe with a lint-free cloth); ensure that the equipment runs stably next time.
[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
