Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a synchronous feeding and unloading device. Background Technology

[0002] In modern intelligent manufacturing and industrial automation, the efficient and continuous operation of printing equipment is crucial for ensuring production efficiency and product quality. Traditional printing equipment typically relies on manual operation or independent mechanical devices for raw material supply and finished product removal, leading to uncoordinated production cycles, low efficiency, and susceptibility to human error or idle equipment. Therefore, achieving automated raw material supply and precise material loading on the printing platform has become a key issue in improving the overall automation level and operational efficiency of printing systems. With the development of industrial robots, precision transmission systems, and intelligent control technologies, automated loading and unloading systems are gradually being applied to various manufacturing equipment. However, in existing technologies, the loading and unloading processes are often performed step-by-step, resulting in time redundancy; or poor synchronization, affecting the continuous operation capability of the printing equipment. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a synchronous feeding and unloading device that enables simultaneous feeding and unloading after processing, thereby enhancing the continuous operation capability of the printing equipment and improving production efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: Design a synchronous feeding and unloading device, including a printing platform, a raw material platform disposed upstream of the printing platform, and a finished product platform disposed downstream of the printing platform, and further including a translation component disposed above the raw material platform and the printing platform. The translation component can reciprocate between the raw material platform and the printing platform. The translation component includes a feeding unit and a unloading unit. When the translation component moves from the raw material platform to the printing platform, the feeding unit picks up raw material from the raw material platform and transfers it to the printing platform, and the unloading unit synchronously pushes the finished product on the printing platform to the finished product platform.

[0005] In this solution, the device integrates a raw material platform, a printing platform, and a finished product platform. Cross-platform linkage is achieved through the upper translation component, avoiding the dispersed arrangement of independent feeding and unloading mechanisms. The translation component simultaneously completes the dual tasks of feeding and unloading during a single movement. While picking up new materials from the raw material platform and transferring them to the printing platform, it pushes the printed finished products to the finished product platform, reducing the idle travel and waiting time of the equipment, lowering the production cycle time, and significantly improving continuous operation capability and production efficiency.

[0006] Furthermore, the device also includes a frame, the printing platform is disposed on the frame, the translation component also includes a slide plate slidably disposed on the frame, the slide plate spans over the printing platform, and the loading unit and unloading unit are disposed on the bottom side of the slide plate facing the printing platform.

[0007] In this solution, the frame provides rigid support for the printing platform, and the slide plate is connected to the frame through a sliding structure to form a stable motion structure that spans the printing platform. The loading and unloading units are integrated on the bottom side of the slide plate, forming an upper-mounted structural layout, which avoids occupying the platform surface and does not interfere with the printing area of ​​the equipment.

[0008] Furthermore, the feeding unit includes a first driving member disposed on the slide plate, a first fixed plate connected to the output end of the first driving member, and a plurality of suction nozzles arrayed on the first fixed plate. The first driving member can drive the first fixed plate to rise and fall so as to drive the suction nozzles to pick up raw materials.

[0009] In this solution, the first driving component can be a cylinder, which drives the first fixed plate to raise and lower the suction nozzles. Several suction nozzles are arranged in an array, and the coordinated action of multiple nozzles provides a stable suction force, avoiding deformation or detachment of raw materials caused by single-point suction. The suction nozzles are integrated through the first fixed plate, and a single damaged nozzle can be replaced independently without disassembling the entire feeding unit, thus reducing maintenance time and costs.

[0010] Furthermore, the nozzle includes a suction portion that can contact the raw material, a fixing portion connected to the first fixing plate, and an elastic portion connecting the suction portion and the fixing portion.

[0011] In this design, the elastic part deforms when the suction part contacts the raw material, buffering the impact force during the suction process and effectively reducing the risk of raw material damage caused by excessive contact pressure. The elastic part's extensibility allows the suction part to adapt to deviations in the placement height of the raw material within a certain range, eliminating the need for frequent adjustments to the lifting stroke of the first drive component. For example, when there are slight fluctuations in the stacking height of the raw material on the platform, the elastic part can automatically compensate for the height difference, ensuring stable adsorption and improving the equipment's tolerance to non-ideal working conditions.

[0012] Furthermore, the feeding unit includes a second driving member disposed on the slide plate, a second fixed plate connected to the output end of the second driving member, and a scraper disposed on the second fixed plate. The second driving member can drive the second fixed plate to rise and fall so that the scraper moves closer to or away from the printing platform.

[0013] In this solution, the second driving component can be a cylinder, which drives the second fixed plate to lift the scraper. The scraper is an integrated plate structure made of rigid material such as metal or high-strength plastic, which can fit tightly with the surface of the printing platform. It can stably push the finished product from the printing platform to the finished product platform through planar thrust.

[0014] Furthermore, the scraper is inclined relative to the surface of the printing platform.

[0015] In this design, the tilted setting makes the scraper contact the printing platform surface with a line rather than a surface, which reduces the friction area and contact pressure, reduces the pushing resistance, and also reduces wear on the printing platform surface.

[0016] Furthermore, support plates are provided at both ends of the slide plate, and the support plates are slidably connected to the frame via linear guide rails.

[0017] In this design, the two ends of the slide plate are connected to the linear guide rail via support plates, forming a fixed support structure at both ends. This design of double-end support plates + linear guide rails has comprehensively improved the translation component in terms of motion accuracy, stability, load-bearing capacity and maintainability, providing core transmission guarantee for the efficient and long-life operation of the synchronous feeding and unloading device.

[0018] Furthermore, the frame is provided with a drive unit for driving the slide plate to move. Two sets of drive units are provided, and the two sets of drive units are respectively connected to the two support plates.

[0019] In this solution, two sets of drive units are independently installed on both sides of the frame. The structure is symmetrical and does not interfere with each other. The two sets of drive units drive the support plates at both ends of the slide plate respectively, forming a "dual-end synchronous drive" structure. This can effectively avoid the torsion or deflection of the slide plate caused by unilateral force. Especially during high-speed start-stop and long-stroke movement, it can significantly reduce the swaying and attitude error of the translation components, ensure the consistency of the movement trajectory of the loading unit and the unloading unit, and improve the positioning accuracy of synchronous operation.

[0020] Furthermore, the drive unit includes two drive wheels rotatably mounted on the frame, a third drive component drivenly connected to one of the drive wheels, and a drive belt wrapped around the two drive wheels. The support plate is located between the two drive wheels, and the two ends of the drive belt are respectively connected to the support plate.

[0021] In this design, the drive belt is meshed with the drive pulleys, and the belt is tensioned by two pulleys, allowing for a large span of travel. Unlike screw drives, it eliminates the need for intermediate supports or anti-sagging structures. Installation only requires adjusting the parallelism and tension of the pulleys, simplifying the debugging process. It also reduces the precision requirements for the frame, lowering assembly difficulty and cost. Support plates are connected to both ends of the drive belt, forming a closed-loop traction structure. When the pulleys rotate clockwise, one end of the belt provides traction; when the pulleys rotate counterclockwise, the other end provides traction.

[0022] Compared with the prior art, the beneficial effects of this utility model are: In this solution, the device integrates a raw material platform, a printing platform, and a finished product platform. Cross-platform linkage is achieved through the upper translation component, avoiding the dispersed arrangement of independent feeding and unloading mechanisms. The translation component simultaneously completes the dual tasks of feeding and unloading during a single movement. While picking up new materials from the raw material platform and transferring them to the printing platform, it pushes the printed finished products to the finished product platform, reducing the idle travel and waiting time of the equipment, lowering the production cycle time, and significantly improving continuous operation capability and production efficiency.

[0030] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0031] like Figure 1 As shown, this embodiment provides a synchronous feeding and unloading device, including a printing platform 2, a raw material platform 1 disposed upstream of the printing platform 2, and a finished product platform 3 disposed downstream of the printing platform 2. The raw material platform 1 and the finished product platform 3 are respectively adjacent to the printing platform 2 and are separately disposed from the printing platform 2. The device also includes a translation component 4 disposed above the raw material platform 1 and the printing platform 2. The translation component 4 can move back and forth between the raw material platform 1 and the printing platform 2. The translation component 4 includes a loading unit 41 and a unloading unit 42. When the translation component 4 moves from the raw material platform 1 to the printing platform 2, the loading unit 41 picks up the raw material from the raw material platform 1 and transfers it to the printing platform 2, and the unloading unit 42 synchronously pushes the finished product on the printing platform 2 to the finished product platform 3. It should be noted that the raw material is a planar sheet material with a certain thickness, and the type of material is not limited, and can be paper, plastic, or wood, etc.

[0032] like Figure 1 and 2As shown, the device also includes a frame 5, with the printing platform 2 mounted on the frame 5. The translation component 4 also includes a sliding plate 43 slidably mounted on the frame 5, spanning across the printing platform 2. A loading unit 41 and a unloading unit 42 are located on the bottom side of the sliding plate 43 facing the printing platform 2. The frame 5 provides rigid support for the printing platform 2. The sliding plate 43 is connected to the frame 5 via a sliding structure, forming a stable motion structure spanning the printing platform 2. The loading unit 41 and the unloading unit 42 are integrated into the bottom side of the sliding plate 43, forming an upper-mounted structural layout, avoiding occupation of the platform surface and not interfering with the printing area of ​​the device. Support plates 44 are respectively provided at both ends of the sliding plate 43, and the support plates 44 are slidably connected to the frame 5 via linear guide rails 45. The two ends of the slide plate 43 are connected to the linear guide rail 45 through the support plate 44 to form a fixed support structure at both ends. This design of double-end support plate 44 + linear guide rail 45 has enabled the translation component 4 to achieve a comprehensive improvement in motion accuracy, stability, load-bearing capacity and maintainability, and provides core transmission guarantee for the efficient and long-life operation of the synchronous feeding and loading device.

[0033] Other, such as Figure 2 As shown, the frame 5 is equipped with a drive unit 6 for moving the slide plate 43. Two sets of drive units 6 are provided, each connected to a support plate 44. The two sets of drive units 6 are independently installed on both sides of the frame 5, with a symmetrical structure and no interference between them. The two sets of drive units 6 drive the support plates 44 at both ends of the slide plate 43, forming a "dual-end synchronous drive" structure. This effectively avoids twisting or deflection of the slide plate 43 due to unilateral force. Especially during high-speed start-stop and long-stroke movement, it significantly reduces the swaying and attitude error of the translation component 4, ensuring the consistency of the movement trajectory between the loading unit 41 and the unloading unit 42, and improving the positioning accuracy of synchronous operation. Specifically, the drive unit 6 includes two drive wheels 61 rotatably mounted on the frame 5, a third drive component 62 driven by one of the drive wheels 61, and a drive belt 63 wrapped around the two drive wheels 61. The third drive component 62 is a drive motor. The support plate 44 is located between the two drive wheels 61, and both ends of the drive belt 63 are connected to the support plate 44. The transmission belt 63 is meshed with the transmission pulleys 61. The transmission belt 63 is tensioned by the two transmission pulleys 61, allowing it to cover a large span of travel. Unlike screw drives, it does not require intermediate supports or anti-sagging structures. During installation, only the parallelism and tension of the transmission pulleys need to be adjusted, simplifying the debugging process. It also reduces the machining accuracy requirements of the frame 5, lowering the difficulty and cost of equipment assembly. Both ends of the transmission belt 63 are connected to support plates 44, forming a closed-loop traction structure. When the transmission pulleys 61 rotate clockwise, one end of the transmission belt 63 provides traction; when the transmission pulleys 61 rotate counterclockwise, the other end of the transmission belt 63 provides traction.

[0034] like Figures 4 to 6As shown, the feeding unit 41 includes a first driving member 411 mounted on a slide plate 43, a first fixed plate 412 mounted at the output end of the first driving member 411, and a plurality of suction nozzles 413 arrayed on the first fixed plate 412. The first driving member 411 can drive the first fixed plate 412 to rise and fall, thereby driving the suction nozzles 413 to pick up raw materials. The first driving member 411 can be a cylinder, which drives the first fixed plate 412 to rise and fall the suction nozzles 413. It should be noted that the number of first driving members 411 is set according to the length of the first fixed plate 412. When the length of the first fixed plate 412 is short, two first driving members 411 can be provided, with the two first driving members 411 respectively located at both ends of the first fixed plate 412. When the length of the first fixed plate 412 is long, multiple first driving members 411 can be provided, and the multiple first driving members 411 are arrayed along the length direction of the first fixed plate 412. Several suction nozzles 413 are arranged in an array and connected to a vacuum generator. The coordinated action of multiple nozzles 413 provides a stable suction force, preventing deformation or detachment of raw materials caused by single-point suction. The nozzles 413 are integrated via a first fixing plate 412, allowing for independent replacement of a damaged nozzle 413 without disassembling the entire feeding unit 41, thus reducing maintenance time and costs. Furthermore, each nozzle 413 includes a suction portion 4131 that contacts the raw material, a fixing portion 4133 connected to the first fixing plate 412, and an elastic portion 4132 connecting the suction portion 4131 and the fixing portion 4133. The elastic portion 4132 deforms when the suction portion 4131 contacts the raw material, buffering the impact during suction and effectively reducing the risk of raw material damage due to excessive contact pressure. The elasticity of the elastic part 4132 allows the suction part 4131 to adapt to the height deviation of the raw material placement within a certain range, without the need to frequently adjust the lifting stroke of the first drive member 411. For example, when there are slight fluctuations in the stacking height of the raw materials on the raw material platform, the elastic part 4132 can automatically compensate for the height difference, ensuring stable adsorption and improving the equipment's tolerance to non-ideal working conditions.

[0035] like Figure 3 and Figure 5As shown, the unloading unit 42 includes a second driving member 421 mounted on a sliding plate 43, a second fixing plate 422 mounted at the output end of the second driving member 421, and a scraper 423 mounted on the second fixing plate 422. The second driving member 421 can drive the second fixing plate 422 to rise and fall, causing the scraper 423 to move closer to or further away from the printing platform 2. The second driving member 421 can be a cylinder, which drives the second fixing plate 422 to move the scraper 423 up and down. It should be noted that the number of second driving members 421 is set according to the length of the second fixing plate 422. When the length of the second fixing plate 422 is short, two second driving members 421 can be provided, with the two second driving members 421 respectively located at both ends of the second fixing plate 422. When the length of the second fixing plate 422 is long, multiple second driving members 421 can be provided, and the multiple second driving members 421 are arranged in an array along the length direction of the second fixing plate 422. The scraper 423 is an integrated plate structure, fixed to the second fixing plate 422 by bolts. The scraper 423 is made of rigid sheet material, such as metal or high-strength plastic, allowing it to fit tightly against the surface of the printing platform 2. It can stably push the finished product from the printing platform 2 to the finished product platform 3 through planar thrust. Furthermore, the scraper 423 is inclined relative to the surface of the printing platform 2, and the bottom cross-section of the scraper 423 is V-shaped. This inclined arrangement ensures that the scraper 423 makes line contact with the surface of the printing platform 2 rather than surface contact. Combined with the V-shaped bottom, this reduces the friction area and contact pressure, lowers pushing resistance, and minimizes wear on the surface of the printing platform 2.

[0036] It should be noted that this device also includes a control system. The operation of all mechanisms is controlled by the control system, which can use existing technology and will not be elaborated on here.

[0037] The operating principle of this device is as follows: The raw material to be printed is stored on the raw material platform 1. After the printing operation on the printing platform 2 is completed, the control system controls the slide plate 43 to move to a preset position above the raw material platform 1. At this time, the suction nozzle 413 is aligned with the preset position of the raw material, and the scraper 423 is located at the edge of the printing platform 2. Then, the first driving component 411 drives the first fixing plate 412 to lower the suction nozzle 413 to contact the raw material. After adsorption is completed, the first driving component 411 drives the first fixing plate 412 to raise the suction nozzle 413 to pick up the raw material. The second driving component 421 drives the second fixing plate 422 to lower the scraper 423 to contact the printing platform 2. Then, the control system controls the slide plate 43 to move towards the preset position of the printing platform 2. During the movement, the scraper 423 pushes the edge of the printed finished product, causing it to move towards the finished product platform 3. When the slide plate 43 moves to the preset position of the printing platform 2, the printed finished product enters the finished product platform 3, and the raw material also arrives at the designated position of the printing platform 2. At this time, the first driving component 411 drives the first fixed plate 412 to lower the suction nozzle 413 to put the raw material into the printing platform 2; the second driving component 421 drives the second fixed plate 422 to raise the scraper 423 to detach from the printing platform 2.

[0038] It should be noted that when the scraper 423 descends, it does not necessarily have to contact the printing platform 2. The distance between the scraper 423 and the printing platform 2 only needs to be less than the height of the raw material.

[0039] In this embodiment, the device integrates a raw material platform 1, a printing platform 2, and a finished product platform 3. Cross-platform linkage is achieved through the upper translation component 4, avoiding the dispersed arrangement of independent feeding and unloading mechanisms. The translation component 4 simultaneously completes the dual tasks of feeding and unloading during a single movement. While picking up new materials from the raw material platform 1 and transferring them to the printing platform 2, it pushes the printed finished products to the finished product platform 3, reducing the idle travel and waiting time of the equipment, lowering the production cycle time, and significantly improving continuous operation capability and production efficiency.
