Description

Technical Field

[0001] The present invention relates to the technical field of laminating machine equipment, and specifically relates to a fully automatic vertical laminating machine. Background Art

[0002] A fully automatic vertical laminating machine is a device specifically used for surface treatment of printed materials. By covering a plastic film on the surface of the printed materials, the glossiness, waterproofness, abrasion resistance and other properties of the printed materials can be improved. This device is widely used in products such as books, picture albums, calendars, magazines, advertising leaflets, etc. The degree of automation of this device is high. From paper feeding to laminating and then to cutting and discharging, the whole process can achieve high automation, reduce manual intervention and improve work efficiency; In order to accurately convey materials from the stacking position to the working area of the laminating machine, the pneumatic feeding mechanism is an important part to realize the automatic feeding function of the fully automatic vertical laminating machine. The vacuum suction cup cooperates with the air source system and uses the vacuum adsorption principle to suck materials. It is often used to suck sheet-shaped or thin materials. At the same time, it is used in cooperation with the material limiting component to limit and adjust the position of the laminating material, ensuring that the laminating material is in the correct position and posture when entering the laminating area, so as to ensure the accuracy and quality of laminating.

[0003] However, it is found in actual applications that when the laminating material moves under the restriction of the limiting component, friction will be generated between the two, and this friction will hinder the smooth conveyance of the laminating material. Therefore, the pneumatic feeding mechanism must overcome this friction to ensure the conveyance of materials. Since the materials of different laminating materials are different, their friction coefficients with the limiting component are also different, resulting in different frictions. If the air pressure of the pneumatic feeding mechanism cannot be accurately adjusted according to the change of materials, when the air pressure is insufficient, it cannot overcome the large friction, and the situation of unstable material grasping will occur, resulting in the material falling or shifting in position during the conveyance process; In addition, the surface of the laminating material is flat, which enables the vacuum suction cup of the pneumatic feeding mechanism to better fit the material surface and form a more effective seal. When the vacuum suction cup adsorbs the upper layer of materials, a certain vacuum area will be formed between the suction cup and the materials. Due to the existence of atmospheric pressure, especially when the gap between the materials is small, when adsorbing the upper layer of materials, the excessive adsorption force may be transmitted to the lower layer of materials through the contact between the materials, resulting in the lower layer of materials being adsorbed as well.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original fully automatic vertical laminating machine. Summary of the Invention

[0005] The technical solution of the present invention aims at the technical problem that the prior art solution is too single, and provides a solution significantly different from the prior art. Specifically, the purpose of the present invention is to provide a fully automatic vertical laminating machine to solve the problems that when feeding materials, the limiting component generates friction with the laminating material, and the pneumatic mechanism cannot accurately adjust the air pressure, resulting in the dropping of materials or the problem of continuous feeding during the feeding process of materials as mentioned in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A fully automatic vertical laminating machine includes a laminating machine body and a loading platform installed on the surface of the laminating machine body. It also includes four symmetrically distributed inductive limit plates arranged on the loading platform that can self-release the laminating material, a deviation correction component arranged on the surface of the loading platform for adjusting the distance between the limit plates and capable of repeatedly straightening the laminating material, and a number of negative pressure channels evenly spaced on the top of the limit plates; A vacuum feeding suction cup is installed directly above the loading platform, and a long magnetic strip is installed on one side of the vacuum feeding suction cup.

[0007] Preferably, two magnetic plates are respectively fixedly connected to the outer sides of the limit plates at both sides of the loading platform, and the polarities of the two magnetic plates are opposite. The magnetic plates sense the magnetic force signal of the long magnetic strip and displace, so that the limit plates at both sides of the loading platform displace along the surface of the loading platform.

[0008] Preferably, one end of a connecting rod is rotatably connected to the bottom of each limit plate, and the other end of the connecting rod is rotatably connected to a rotating frame. The rotating frame and the connecting rod are embedded inside the loading platform. When the rotating frame rotates, the four limit plates perform relative movement through the transmission of the connecting rod.

[0009] Preferably, the deviation correction component includes two main rods slidably connected to both sides of the loading platform, a spring arranged at the top inner wall of the main rod, and a vertical rod sleeved inside the spring. A gravity ball is fixedly connected to the bottom of the vertical rod; One side of the main rod is threadedly connected with a lead screw, and by rotating the lead screw, the main rod is driven to slide along the surface of the loading platform.

[0010] Preferably, a rocker is rotatably connected to one side of each main rod. One end of the rocker is in contact with the gravity ball, and the other end of the rocker is in contact with the surface of the limit plate; When the limit plate expands outwards to squeeze the rocker to swing, the spring is compressed to generate a resilience force. The resilience force after the spring is compressed is transmitted to the rocker through the gravity ball, causing the rocker to perform a periodic reciprocating swinging motion, and further driving the limit plate to reciprocally slide along the surface of the loading platform.

[0011] Preferably, an arc-shaped sliding groove is provided on the surface of the main rod, and one end of the rocker near the gravity ball slides along the arc-shaped sliding groove. A clamping strip for blocking the rocker is provided on the outer side of the limiting plate. Expansion rods movably connected to the limiting plates are installed at both ends of each main rod.

[0012] Preferably, the negative pressure channel is divided into a main channel and a side channel. The middle part of the main channel is narrower than both ends. The side channel is installed at the middle position of the main channel and is inclined towards the position of the vacuum feeding suction cup.

[0013] Preferably, the main channel penetrates through the top of the limiting plate. When the limiting plates approach each other, external air enters the main channel. When the air flows through the side channel, the flow rate increases, causing a negative pressure to form in the side channel.

[0014] Preferably, the laminating machine body includes a frame, a film rack installed on the top of the frame, a film guiding roller provided below the film rack. A film pressing roller for pressing the laminating material is installed on one side of the film guiding roller. The laminating machine body further includes a main controller installed on one side of the vacuum feeding suction cup.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The laminating material is clamped and limited by four symmetrically distributed inductive limiting plates. According to the principle of like poles repelling each other, when the limiting plates on both sides sense the magnetic force signal of the long magnetic strip, they will automatically unfold slightly outward, thereby automatically releasing the laminating material. The certain gap formed between the limiting plate and the laminating material can prevent mutual friction between them, ensuring that the laminating material can be smoothly and steadily adsorbed by the vacuum feeding suction cup.

[0016] In addition, after the feeding of the laminating material is completed, the repulsive magnetic force of the magnetic plates decreases. At this time, the spring is compressed to the maximum extent, and the spring presses the gravity ball, causing the gravity ball to repeatedly impact the rocker, resulting in a periodic reciprocating swinging motion of the rocker. The other end of the rocker continuously presses the limiting plate, causing it to slide reciprocally along the surface of the loading platform, thereby repeatedly correcting and straightening the material, repeatedly patting the laminating material, imitating the effect of manual sorting, and ensuring continuous deviation correction and calibration of the laminating material.

[0017] Meanwhile, when the limiting plates move inward to reset, external air flows into the main channel along with the trend. When the air flows through the installation position of the side channel, the flow cross-sectional area suddenly decreases. According to the principle of fluid mechanics, the gas flow rate increases, and the increase in flow rate causes the air pressure in the side channel to rapidly decrease, thereby forming a negative pressure environment, breaking the balance of the atmospheric pressure, and adsorbing the associated materials, avoiding associated feeding.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a fully automatic vertical laminating machine, including a laminating machine body 1 and a loading platform 2 installed on the surface of the laminating machine body 1, and further including four symmetrically distributed inductive limit plates 3 arranged on the loading platform 2 and capable of self-releasing the laminating material, a deviation rectifying assembly 4 arranged on the surface of the loading platform 2 for adjusting the distance between the limit plates 3 and capable of repeatedly straightening the laminating material, and a plurality of negative pressure channels 5 equally spaced and distributed on the top of the limit plates 3; A vacuum feeding suction cup 6 is installed directly above the loading platform 2, and a long magnetic strip 7 is installed on one side of the vacuum feeding suction cup 6.

[0027] The material to be coated is clamped and fixed by four symmetrically distributed limit plates 3. When the vacuum loading suction cup 6 descends and approaches, the limit plates 3 sense the magnetic signal of the long magnetic strip 7 of the vacuum loading suction cup 6, and the spacing between the limit plates 3 slightly expands outward, thereby automatically releasing the coating material. A certain gap formed between the limit plates 3 and the coating material can prevent mutual friction between them, ensuring that the coating material can be stably and smoothly adsorbed by the vacuum loading suction cup 6.

[0028] In addition, after the coating material is loaded, the limit plate 3 will automatically move together. The correction component 4 will repeatedly squeeze the limit plate 3, so that the limit plate 3 will repeatedly beat the coating material, imitating the effect of manual sorting, ensuring that the coating material is continuously corrected and calibrated. At the same time, the negative pressure channel 5 will absorb excess coating material to avoid loading.

[0029] In this embodiment, if Figure 2 and Figure 3 As shown, the outer side surfaces of the limit plates 3 located on both sides of the loading platform 2 are fixedly connected to two magnetic plates 8, and the polarities of the two magnetic plates 8 are opposite. The magnetic plates 8 sense the magnetic signals of the long magnetic strips 7 and move, so that the limit plates 3 on both sides of the loading platform 2 move along the surface of the loading platform 2.

[0030] At the bottom of each limit plate 3, one end of a connecting rod 9 is rotatably connected, and the other end of the connecting rod 9 is rotatably connected to a rotating frame 10. The rotating frame 10 and the connecting rod 9 are embedded in the interior of the loading platform 2. When the rotating frame 10 rotates, the four limit plates 3 move relative to each other through the transmission of the connecting rod 9.

[0031] It should be noted that the magnetic plates 8 on the limit plates 3 on both sides of the loading platform 2 have opposite magnetic poles. When the vacuum loading suction cup 6 descends, the two ends of the long magnetic strip 7 will correspond to the two magnetic plates 8 respectively. The magnetic poles at both ends of the long magnetic strip 7 are consistent with the magnetic poles of the corresponding magnetic plates 8. According to the principle of like poles repel each other, the limit plates 3 on both sides will automatically expand slightly outward after sensing the magnetic signal of the long magnetic strip 7.

[0032] Similarly, the four limit plates 3 are connected to the rotating frame 10 through the connecting rod 9 to form a linkage mechanism. When the limit plates 3 on both sides are driven to expand outward by the magnetic force, the connecting rod 9 will be pulled to swing, and then the rotating frame 10 will be driven to rotate, so that the other two limit plates 3 can move synchronously, so that the four limit plates 3 can expand outward or move inward at the same time, and the coating material can be loosened or clamped at the same time. At this time, during the feeding process, a certain gap is formed between the limit plates 3 and the coating material to avoid mutual friction, and the feeding process is more stable.

[0033] In this embodiment, if Figure 4 and Figure 5As shown, the deviation correction component 4 includes two main rods 401 slidably connected to the two sides of the loading platform 2, a spring 402 arranged on the top of the inner wall of the main rod 401 and a vertical rod 403 sleeved inside the spring 402, and a gravity ball 404 is fixedly connected to the bottom of the vertical rod 403.

[0034] A screw rod 405 is threadedly connected to one side of the main rod 401 , and the main rod 401 is driven to slide along the surface of the loading platform 2 by rotating the screw rod 405 .

[0035] It should be noted that by rotating the screw rod 405, its rotational action will be transmitted to the main rod 401, causing the main rod 401 to slide along the surface of the loading platform 2. When the main rod 401 slides, it will push the corresponding limit plate 3 to move synchronously, and the two limit plates 3 begin to move synchronously toward the center. The connecting rod 9 begins to drive the rotating frame 10 to rotate, further driving the other two limit plates 3 to move synchronously. The main rod 401 is limited by the screw rods 405 on both sides. The screw rods 405 have a self-locking function to control the maximum displacement range of the four limit plates 3.

[0036] Specifically, when the screw rod 405 rotates forward, it will drive the main rod 401 at the corresponding position to slide toward the inside of the loading platform 2, causing the main rod 401 to move inward synchronously, prompting the four limit plates 3 to move toward the center at the same time, thereby clamping and fixing the material to be coated. The double-sided clamping has a better limiting effect, and when the screw rod 405 is reversed, the four limit plates 3 will expand outward synchronously.

[0037] In this embodiment, if Figure 5 As shown, one side of each main rod 401 is rotatably connected to a rocker 406 , one end of the rocker 406 is in contact with the gravity ball 404 , and the other end of the rocker 406 is in contact with the surface of the limiting plate 3 .

[0038] The limit plate 3 is expanded outward to squeeze the rocker 406 to swing, so that the spring 402 is compressed to generate a rebound force. The rebound force of the compressed spring 402 is transmitted to the rocker 406 through the gravity ball 404, causing the rocker 406 to perform a periodic reciprocating swing motion, further driving the limit plate 3 to slide back and forth along the surface of the loading platform 2.

[0039] In this embodiment, the two ends of the rocker arm 406 are in contact with the inner wall of the main rod 401 and the surface of the limit plate 3 respectively. The gravity ball 404, under the combined action of the elastic force of the spring 402 and its own gravity, presses against one end of the rocker arm 406, thereby controlling the angle between the rocker arm 406 and the main rod 401. When the limiter equipped with the magnetic plate 8 senses the magnetic signal of the long magnetic strip 7, the limit plates 3 on both sides begin to expand to both sides. As the limit plates 3 on both sides move, the other two limit plates 3 also begin to move synchronously.

[0040] Meanwhile, during the outward movement of the limit plate 3, they will squeeze the rocker 406 again, causing the end of the rocker 406 close to the limit plate 3 to start deflecting downward, while the other end of the rocker 406 deflects upward, squeezing the gravity ball 404 to move upward, and accompanied by the compression of the spring 402. After the vacuum feeding suction cup 6 adsorbs the material and moves away from the limit plate 3, the repulsive magnetic force of the magnetic plate 8 decreases. At this time, the spring 402 is compressed to the maximum extent, and the elastic force of the spring 402 squeezes the gravity ball 404, causing the gravity ball 404 to repeatedly impact the rocker 406, resulting in a periodic reciprocating swinging motion of the rocker 406. The other end of the rocker 406 continuously squeezes the limit plate 3, causing it to slide reciprocally along the surface of the loading platform 2, thereby repeatedly correcting and straightening the material.

[0041] In addition, it should be noted that a vertical rod 403 is sleeved inside the spring 402. The vertical rod 403 is used to limit the compression and rebound path of the spring 402. The bottom of the vertical rod 403 is connected to the gravity ball 404. Under the repeated rebounding action of the spring 402, the gravity ball 404 drives the spring 402 to reciprocally rebound along the length direction of the vertical rod 403 to prevent the spring 402 from bending during the compression process.

[0042] In this embodiment, as Figure 4 shown, an arc-shaped chute is provided on the surface of the main rod 401. One end of the rocker 406 close to the gravity ball 404 slides along the arc-shaped chute. A card strip 408 for blocking the rocker 406 is provided on the outer side surface of the limit plate 3.

[0043] Both ends of each main rod 401 are equipped with telescopic rods 407 that are movably connected to the limit plate 3.

[0044] It should be noted that in this embodiment, one end of the rocker 406 is close to the gravity ball 404 and is embedded in the arc-shaped chute. The arc-shaped chute is used to control the swinging path of the rocker 406 during its swinging process.

[0045] The main rod 401 is connected to the limit plate 3 through the telescopic rod 407. When the limit plate 3 undergoes displacement, the telescopic rod 407 will be correspondingly compressed, thereby assisting the limit plate 3 to move vertically backward along the main rod 401. At the same time, the rocker 406 is blocked by the card strip 408, causing the rocker 406 to always tilt towards the limit plate 3 side to prevent the spring 402 from being stretched reversely.

[0046] In this embodiment, as Figure 6 shown, the negative pressure channel 5 is divided into a main channel 501 and a side channel 502. The middle part of the main channel 501 is narrower than both ends. The side channel 502 is installed at the middle position of the main channel 501, and the side channel 502 is inclined towards the position of the vacuum feeding suction cup 6.

[0047] The main channel 501 passes through the top of the limiting plates 3 . When the limiting plates 3 are brought close to each other, external airflow enters the main channel 501 . When the airflow flows through the side channel 502 , the flow velocity is accelerated, so that negative pressure is formed in the side channel 502 .

[0048] It should be noted that a row of negative pressure channels 5 are evenly spaced at the top of the limiting plate 3, and the negative pressure channels 5 are composed of a main channel 501 and a side channel 502, wherein the middle part of the main channel 501 is narrower, and the side channel 502 is installed at the narrower position in the middle of the main channel 501, and the side channel 502 faces the vacuum feeding suction cup 6 at a certain inclination angle; When the limit plate 3 moves inward, the external air flows into the main channel 501. Due to the special structure of the main channel 501 which is narrow in the middle and wide at both ends, the flow cross-sectional area decreases sharply when the airflow flows through the installation position of the side channel 502. According to the principles of fluid mechanics, the gas flow rate is accelerated. The increased flow rate causes the air pressure in the side channel 502 to decrease rapidly, thereby forming a negative pressure environment. Negative pressure is formed on the top of multiple side channels 502, generating a certain downward adsorption force. Once the vacuum loading suction cup 6 entrains the lower layer material when adsorbing the upper layer material, the negative pressure formed by the negative pressure channel 5 breaks the balance of the atmospheric pressure and adsorbs the associated material.

[0049] In addition, it should be pointed out that the side channels 502 of the negative pressure channels 5 on the top of the four limiting plates 3 are all inclined toward the direction of the vacuum loading suction cup 6, so that the suction force is more concentrated, thereby improving the adsorption effect, and the adsorbed coating material can be returned to its original position.

[0050] In this embodiment, if Figure 1 As shown, the laminating machine body 1 includes a frame 101, a film frame 102 installed on the top of the frame 101, and a film guide roller 103 arranged below the film frame 102. A film pressing roller 104 for applying pressure to the laminating material is installed on one side of the film guide roller 103. The laminating machine body 1 also includes a main controller 105 installed on one side of the vacuum loading suction cup 6.

[0051] It should be noted that the film rack 102 is used to store the coating layer, and the coating layer is transported by guiding the film guide roller 103. When the vacuum loading suction cup 6 delivers the material to be coated into place under the control of the main controller 105, the film pressing roller 104 applies pressure to the coating material and the coating layer released by the film rack 102 under the control of the main controller 105, so that the two are tightly fitted to complete the coating process. The whole process is coordinated by the main controller 105 to ensure the orderly operation of various components, and its structure and principle are well known technologies in the art.

[0052] Working principle: When using the fully automatic vertical laminating machine: first, stack the materials to be coated in batches on the loading platform 2, rotate the screw rods 405 on both sides, so that the main rods 401 on both sides slide toward the center, and as the main rods 401 on both sides slide toward the center, the extrusion limit plates 3 move toward the center synchronously, and under the linkage of the connecting rod 9 and the rotating frame 10, the four limit plates 3 clamp and fix the coating materials; Then, the main controller 105 controls the vacuum feeding suction cup 6 to start moving, absorbs the material to be coated, and transmits it to the front film pressing roller 104 to start coating. During the descent of the vacuum feeding suction cup 6, the long magnetic strip 7 descends with it. As the long magnetic strip 7 descends, the magnetic plates 8 on the back of the limit plates 3 on both sides sense the magnetic signal of the long magnetic strip 7, and the same level repels each other. The limit plates 3 on both sides expand slightly outward due to the influence of the magnetic force. Through the transmission of the connecting rod 9, the rotating frame 10 starts to rotate, driving the other two limit plates 3 to expand outward synchronously. Next, as the limit plate 3 expands outward, since the position of the main rod 401 is limited, when the limit plate 3 expands outward, the squeezing rocker 406 starts to swing, and the end of the rocker 406 close to one end of the limit plate 3 moves down, while the other end rises, squeezing the gravity ball 404 and the vertical rod 403 to slide up along the main rod 401, accompanied by the compression of the spring 402; When the vacuum feeding suction cup 6 absorbs the coating material and moves upward, the long magnetic strip 7 moves upward synchronously with it. At this time, the long magnetic strip 7 and the magnetic plate 8 are staggered and not in the same horizontal plane. The magnetic influence is reduced. Under the elastic force of the spring 402 and the gravity of the gravity ball 404, the gravity ball 404 begins to reset. During the resetting process of the gravity ball 404, due to the elastic force of the spring 402, the rocker 406 is repeatedly struck, causing the rocker 406 to swing back and forth periodically, further driving the limit plate 3 to slide back and forth synchronously, and repeatedly sorting the materials on the loading platform 2; At the same time, in the process of the limit plates 3 quickly moving toward the center and resetting, an airflow is formed between the limit plates 3, and the airflow enters the negative pressure channel 5. When the airflow flows through the side channel 502, the main channel 501 becomes narrower, the airflow speed increases, and the air pressure in the side channel 502 decreases rapidly, thereby forming a negative pressure environment, which can absorb the associated materials.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
