Description

Technical Field

[0001] This invention relates to the field of laminator technology, specifically a roller conveyor laminator. Background Technology

[0002] As a mechanical device that presses multiple layers of material together, the quality of the laminator determines the overall lamination quality.

[0003] For example, the patent for a laminator and an alignment adjustment method for the laminator with publication number CN112313063B makes it easier to align and adjust a laminator performing vacuum lamination. The laminator includes: a vacuum chamber; a roller disposed within the vacuum chamber for vacuum lamination; an alignment adjustment mechanism for adjusting the alignment of the roller; and an actuator that generates a driving force to rotate the roller. The front end of the output-side rotating shaft that outputs the driving force of the actuator is disposed outside the vacuum region, and the front end of the input-side rotating shaft that inputs the driving force to rotate the roller is disposed inside the vacuum region. The front end of the output-side rotating shaft is electromagnetically connected to the front end of the input-side rotating shaft.

[0004] For example, the patented steel belt type polyurethane continuous laminator with publication number CN102285189B includes an upper laminator, a lower laminator, and a lifting cylinder. The upper and lower laminators are supported and fixed by the lifting cylinder. The upper laminator includes a front roller I, a rear roller I, and a steel belt I, with the steel belt I sleeved outside the front roller I and rear roller I. The lower laminator includes a front roller II, a rear roller II, and a steel belt II, with the steel belt II sleeved outside the front roller II and rear roller II. This improves upon existing tank chain / tank belt type production lines by using a continuous steel belt, allowing the laminator to operate continuously. Furthermore, the use of a multi-layer conveyor support reduces the friction coefficient between the steel belt and the support surface, thus lowering the operating load.

[0005] For example, patent CN202753545U discloses a laminating machine, belonging to the field of mechanical technology. It solves the problem of cumbersome installation and removal of adhesive sheets in existing laminating machines. This laminating machine includes a feeding platform, a laminating platform, a discharging platform, and a main unit. The feeding platform and discharging platform are located on the front and rear sides of the main unit. The laminating platform is installed directly above the main unit via a lifting device. The lower surface of the laminating platform is covered with adhesive sheets. The main unit is equipped with a heating system, a vacuum system, and a control system. The heating system, vacuum system, and lifting device are all connected to and controlled by the control system. The adhesive sheets are fixed to the laminating platform by a locking device. It has the advantage of making the installation and removal of adhesive sheets simple and convenient.

[0006] Most of the existing technologies mentioned above improve the overall structure. However, the main working machine of the existing laminator uses traditional PTFE cloth transmission for the internal transmission of the lamination chamber. This transmission method is not stable enough and is prone to transmission deviation. At the same time, it cannot achieve the working effect of lamination and heating at the same time during transmission, thus having certain limitations in use. Summary of the Invention

[0007] The purpose of this invention is to provide a roller conveyor laminator to solve the problems mentioned in the background art, where the main working machine of the laminator is driven by a traditional PTFE cloth drive, which is not stable enough and is prone to deviation. At the same time, it cannot achieve the working effect of conveying and laminating at the same time, and heating at the same time.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a roller conveyor laminator, comprising a laminator body, wherein a permanent magnet roller assembly is mounted on the end side of the laminator body; a driven roller assembly is rotatably connected to the inner side of the laminator body, and the shaft end of the driven roller assembly is engaged with a first synchronous chain, the end of the first synchronous chain being engaged with the output end of the permanent magnet roller assembly; the driven roller assemblies are evenly distributed about the center point of the laminator body, and the end sides of the driven roller assemblies are engaged with each other by a second synchronous chain; the permanent magnet roller assembly and the driven roller assembly are directly embedded in the lamination chamber of the laminator body to achieve the purpose of conveying the components; an auxiliary guiding structure is provided on the inner side of the driven roller assembly, which adaptively prevents skewness during conveying of the conveyed items.

[0009] More preferably, the auxiliary guiding structure is provided with a reserved synchronous belt, and the reserved synchronous belt is sleeved on the outside of the driven roller assembly. An abutment is nested on the inner side of the side end of the driven roller assembly, and a first spring is fixedly connected to the outside of the abutment, and the first spring is in contact with the inner wall of the driven roller assembly. An electric heating component is provided at the middle of the inner side of the driven roller assembly.

[0010] More preferably, a horizontal guide groove is provided at the middle of the inner side of the abutting docking member, and a docking connector is nested inside the horizontal guide groove. A second spring is fixedly connected to the outer side of the docking connector, and the second spring is connected to the middle of the inner side of the abutting docking member. A first reserved steel rope is connected to the outer side of the docking connector, and the first reserved steel rope passes through the interior of the abutting docking member, and the end of the first reserved steel rope is connected to the outer side of the abutting docking member.

[0011] More preferably, the outer wall of the abutting joint is rotatably connected with a built-in movable piece, and the built-in movable piece corresponds to the upper end position of the abutting joint, and the built-in movable piece is symmetrically distributed about the center point of the abutting joint.

[0012] More preferably, when the upper lamination chamber at the upper end of the laminator body moves down to contact the surface of the driven roller assembly, it will apply pressure inward to the contacting mating member, and the contacting mating member will move downward along the inner side of the driven roller assembly through the first spring. The contacting mating member will form a traction operation with the docking connector through the first reserved steel rope.

[0013] More preferably, the docking connector moves laterally along the inner side of the transverse guide groove via a second spring, and the upper end of the docking connector applies pressure to the bottom of the contacting built-in movable piece, so that it forms a rotational horizontal support along the inner side of the contacting docking connector, ensuring the flatness of the lamination.

[0014] More preferably, the inner side of the driven roller assembly is provided with an adaptive heat conduction structure, which adaptively guides and releases the heat stored inside the driven roller assembly; the adaptive heat conduction structure is provided with a sealing docking part, and the sealing docking part is nested and docked at the lower end of the abutting docking part; a third spring is fixedly connected to the outer side of the sealing docking part, and the upper end of the third spring is docked with the lower end of the abutting docking part.

[0015] More preferably, the lower outer side of the sealing docking member and the inner side of the contact docking member are both fixedly connected with magnetic docking members, and the magnetic docking members are opposite magnetic poles, while the positions of the two sets of magnetic docking members correspond to each other.

[0016] More preferably, as the abutting component moves downward along the inner side of the driven roller assembly under pressure, the sealing component at its lower end will move accordingly when it comes into contact with the magnetic attraction of the magnetic component inside the abutting component, causing the sealing component to stretch the third spring to move along the lower end of the abutting component, so that the abutting component is in the connected state.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This roller conveyor laminator changes the traditional PTFE cloth drive in the lamination chamber of the laminator body to a permanent magnet roller assembly drive. The permanent magnet roller assembly is installed at the end of the laminator body chamber, integrating the motor and drive shaft into one unit. Multiple driven roller assemblies are driven by a synchronous chain drive after the permanent magnet roller assembly. These driven roller assemblies are directly embedded in the lamination chamber, achieving efficient and stable component transfer, preventing deviation. Furthermore, the driven roller assemblies have a hollow structure, with intervals serving as vacuum lines or electric heating components. This integrates the functions of a traditional laminator, enabling fast and efficient operation, significantly improving work efficiency, shortening lamination time, and achieving simultaneous lamination and heating during transfer.

[0019] Furthermore, an auxiliary guiding structure is provided to adaptively prevent skewness during the conveying of objects. In normal conveying mode, the surface of the driven roller assembly forms a concave conveying structure through the built-in movable piece, allowing the objects conveyed on the surface to be stably conveyed inward, avoiding skewness. When the upper lamination chamber at the top of the laminator moves down to contact the surface of the driven roller assembly for lamination, it will apply pressure inward to the pre-stressed contact joint. The contact joint will then drive the connecting piece to move laterally along the inner side of the horizontal guide groove through the first reserved steel rope. This will allow the upper end of the connecting piece to apply pressure to the bottom of the contacting built-in movable piece, forming a rotating horizontal support along the inner side of the contact joint, ensuring the flatness of the lamination. In other words, the flatness is adaptively ensured during lamination. During normal conveying, the concave conveying structure prevents the conveyed objects from skewing.

[0020] Furthermore, an adaptive heat conduction structure is provided. This structure adaptively guides and releases the heat stored inside the driven roller assembly. When the contact mating parts are pressed and move downwards along the inner side of the driven roller assembly, the sealing mating parts at their lower ends will contact the magnetic mating parts inside the contact mating parts. Through the magnetic attraction, the sealing mating parts move, causing the third spring to stretch along the lower end of the contact mating parts, thus putting the contact mating parts in a connected state. This allows the heat stored inside the driven roller assembly to be collected and guided along the contact mating parts, thus carrying out heat conduction in an orderly manner. While ensuring the quality of heat transfer, this avoids the negative effects of excessively high internal temperatures in the driven roller assembly, improving the practicality of the device.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-9 The present invention provides the following technical solution: a roller conveyor laminator, which, in order to solve the defects of the traditional transmission method being unstable and unable to achieve the working effect of simultaneous transmission and lamination, and simultaneous heating during transmission, discloses: a permanent magnet roller assembly 2 is installed on the end side of the laminator body 1; a driven roller assembly 4 is rotatably connected to the inner side of the laminator body 1, and the shaft end of the driven roller assembly 4 is meshed with a first synchronous chain 3, and the end of the first synchronous chain 3 is connected to the output end of the permanent magnet roller assembly 2; the driven roller assemblies 4 are evenly distributed about the center point of the laminator body 1, and the end sides of the driven roller assemblies 4 are meshed with a second synchronous chain 5; the permanent magnet roller assembly 2 and the driven roller assembly 4 are directly embedded in the lamination chamber of the laminator body 1 to achieve the purpose of component transmission;

[0033] An auxiliary guiding structure is provided on the inner side of the driven roller assembly 4. This structure provides adaptive anti-skew conveying of the transported items. The auxiliary guiding structure includes a reserved synchronous belt 6, which is fitted onto the outer side of the driven roller assembly 4. An abutment member 7 is nested inside the inner side of the driven roller assembly 4, and a first spring 8 is fixedly connected to the outer side of the abutment member 7. The first spring 8 abuts against the inner wall of the driven roller assembly 4. An electric heating component 17 is provided at the middle inner side of the driven roller assembly 4. A horizontal guide groove 13 is formed at the middle inner side of the abutment member 7, and a component is nested inside the horizontal guide groove 13. A connecting member 10 is provided, and a second spring 11 is fixedly connected to the outer side of the connecting member 10. The second spring 11 is connected to the inner middle of the contacting member 7. A first reserved steel rope 9 is connected to the outer side of the connecting member 10, and the first reserved steel rope 9 passes through the interior of the contacting member 7. The end of the first reserved steel rope 9 is connected to the outer side of the contacting member 7. An internal movable piece 12 is rotatably connected to the outer wall of the contacting member 7. The internal movable piece 12 corresponds to the upper end position of the connecting member 10, and the internal movable pieces 12 are symmetrically distributed about the center point of the contacting member 7. The upper part of the laminator body 1... When the laminating chamber moves down to contact the surface of the driven roller assembly 4, it will apply inward pressure to the contacting mating member 7. The contacting mating member 7 moves downward along the inner side of the driven roller assembly 4 via the first spring 8. The contacting mating member 7 forms a traction operation with the docking connector 10 via the first reserved steel rope 9. The docking connector 10 moves laterally along the inner side of the transverse guide groove 13 via the second spring 11. The upper end of the docking connector 10 applies pressure to the bottom of the contacting built-in movable piece 12, causing it to form a rotational horizontal support along the inner side of the contacting mating member 7, ensuring the flatness of the lamination. The main working machine of the laminating chamber of the laminating machine body 1 transmits pressure. The motor is no longer driven by traditional PTFE cloth, but by permanent magnet roller assembly 2. Permanent magnet roller assembly 2 is installed at the end of the chamber of the laminator body 1, integrating the motor and drive shaft into one unit. Multiple driven roller assemblies 4 are driven by synchronous chain drive after permanent magnet roller assembly 2. The driven roller assemblies 4 are directly embedded in the lamination chamber to achieve the purpose of component transfer. It is efficient and stable, prevents motor deviation, and the driven roller assembly 4 has a hollow structure. The intervals are used as vacuum pipelines or electric heating component 17 units. It integrates the functions of traditional laminators and works quickly and efficiently, greatly improving work efficiency, shortening lamination time, and realizing lamination while transferring, and heating at the same time.The auxiliary guiding structure provides adaptive anti-skew conveying of transported items. In normal conveying mode, the surface of the driven roller assembly 4 forms a concave conveying structure through the built-in movable piece 12, ensuring stable inward conveying of items and preventing skew. When the upper lamination chamber at the top of the laminator body 1 moves down to contact the surface of the driven roller assembly 4 for lamination, it applies pressure inward to the pre-stressed contact joint 7. This causes the contact joint 7 to move laterally along the inner side of the transverse guide groove 13 via the first reserved steel rope 9. This pressure causes the upper end of the contact joint 10 to press against the bottom of the contacting built-in movable piece 12, creating a rotating horizontal support along the inner side of the contact joint 7, ensuring lamination flatness. In other words, the flatness is adaptively maintained during lamination, and the concave conveying structure prevents skewed movement of transported items during normal transport.

[0034] Example 2: Based on Example 1, in order to solve the problem of transmission deviation, an adaptive heat conduction structure is also disclosed. The specific structure is as follows: An adaptive heat conduction structure is provided on the inner side of the driven roller assembly 4. The heat stored inside the driven roller assembly 4 is adaptively guided and depressurized through the adaptive heat conduction structure.

[0035] The adaptive heat conduction structure is equipped with a sealing docking member 14, which is nested and docked at the lower end of the contact docking member 7. A third spring 16 is fixedly connected to the outer side of the sealing docking member 14, and the upper end of the third spring 16 is docked with the lower end of the contact docking member 7. Magnetic attraction docking members 15 are fixedly connected to both the outer side of the lower end of the sealing docking member 14 and the inner side of the contact docking member 7. The magnetic attraction docking members 15 have opposite magnetic poles and are positioned correspondingly. As the contact docking member 7 is pressed and moves downward along the inner side of the driven roller assembly 4, the sealing docking member 14 at its lower end will move accordingly when it contacts the magnetic attraction of the magnetic attraction docking member 15 on the inner side of the contact docking member 7, causing the sealing docking member 14 to stretch. The third spring 16 moves along the lower end of the contact joint 7, so that the contact joint 7 is in the connected state. When the contact joint 7 is pressed down along the inner side of the driven roller assembly 4 in the contact lamination state, the sealing joint 14 at its lower end will contact the magnetic attraction joint 15 on the inner side of the contact joint 7 and move accordingly through its magnetic attraction force, so that the sealing joint 14 stretches the third spring 16 to move along the lower end of the contact joint 7, so that the contact joint 7 is in the connected state. This allows the heat stored inside the driven roller assembly 4 to be collected and guided along the contact joint 7, so as to carry out heat conduction in an orderly manner. While ensuring the quality of heat transfer guidance, it avoids the negative effects of excessively high internal temperature of the driven roller assembly 4.
