Description

Technical Field

[0001] This utility model relates to the field of synthetic paper materials, and more specifically, it relates to a printing device for the adhesive surface of synthetic paper materials. Background Technology

[0002] Synthetic paper is a new type of material that combines some properties of plastics and paper, and it has wide applications in many fields. In terms of raw materials, synthetic paper mainly uses polyolefin plastics such as polyethylene and polypropylene as its main raw materials, and sometimes fillers such as calcium carbonate are added to improve material properties. Its production process is relatively complex. First, the raw materials are heated and melted, then extruded into thin sheets using an extruder. Afterwards, a stretching process is performed to align the molecular chains of the material in a certain direction, a process that significantly improves the material's strength and other properties. In subsequent processing, special methods, such as surface treatment technology, are used to give synthetic paper a paper-like appearance and feel. Synthetic paper possesses many excellent properties. In terms of physical properties, it has very high strength; both its tensile strength and tear strength are much better than ordinary paper, allowing it to withstand greater external forces without easily being damaged. Its dimensional stability is good; it does not exhibit significant expansion or contraction due to changes in ambient temperature and humidity, making it excellent in applications requiring high dimensional accuracy. Meanwhile, the relatively smooth surface of synthetic paper provides a good foundation for high-quality printing, which can clearly present the printed patterns and text. Synthetic paper materials are often used to produce self-adhesive labels.

[0003] When printing on the adhesive side of existing synthetic paper materials, the paper travels a long path. In order to ensure the continuity of the printing process, a certain amount of paper needs to be stored in a paper storage rack. In addition, anti-stick rollers are needed to prevent the adhesive side from sticking to other parts before it is dry or cured. If it is double-sided printing, the paper also needs to be flipped by a flipping rack. During this process, the synthetic paper material is very easy to be damaged by friction.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an adhesive printing apparatus for synthetic paper materials. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing device for adhesive surface of synthetic paper materials.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a printing device for adhesive surface of synthetic paper material, comprising a support platform, wherein a bidirectional printing base, a UV curing device and a laminating device are arranged horizontally in sequence at the top of the support platform, and a tension manual adjustment mechanism is installed between the UV curing device and the laminating device.

[0007] Preferably, the tension manual adjustment mechanism includes a manual lifting component that drives the tension roller assembly to move up and down, and a buffer component is installed between the manual lifting component and the tension roller assembly.

[0008] Preferably, the buffer assembly includes a grooved seat fixed to the head of the manual lifting assembly, the inner bottom end of the grooved seat is fixed to the lifting plate by a spring, and the top end of the lifting plate is fixed to the bottom of the tension roller assembly by a vertical rod.

[0009] Preferably, the two sides of the groove seat are fixedly connected to guide rails, and the two sides of the lifting plate are slidably connected to the guide rails by sliders to maintain the vertical linear movement of the lifting plate.

[0010] Preferably, the manual lifting assembly is provided with a handle that is easy for the operator to operate. A connecting plate is fixedly connected to the manual lifting assembly next to the handle, and a screw is connected to the internal thread of the connecting plate. When in use, the screw is rotated clockwise so that the end of the screw abuts against the handle rod to limit the rotation of the handle and prevent its state from being changed by the vibration of the device during normal use.

[0011] Preferably, a storage cabinet is fixedly connected to the bottom of the support platform, which can support the device at an appropriate height, making it convenient to use in conjunction with other devices.

[0012] Preferably, the bottom of the storage cabinet is fixedly connected to a cast iron counterweight base to stably support the device.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model changes the complex process of traditional adhesive printing, simplifying and eliminating the use of paper storage racks, anti-stick rollers, and flipping frames. At the same time, it reduces the physical damage to the adhesive surface caused by the anti-stick rollers. For special materials, it can avoid friction damage to the raw materials caused by the flipping frame. Moreover, the convenience and stability of this device are greatly improved compared to traditional adhesive printing methods. It also saves machine setup time, reduces raw material loss, and lowers production costs, thereby solving the problem of needing to use paper storage racks, anti-stick rollers, and flipping frames in the background technology.

[0015] 2. The buffer assembly 53 installed below the tension roller assembly 52 of this invention can automatically adjust according to changes in tension, compensating for tension fluctuations and keeping the paper tension relatively stable.

[0016] 3. After the manual lifting assembly of this utility model has been adjusted, rotate the screw 8 clockwise. The screw 8 moves along the connecting plate 7 toward the handle 7, so that the end of the screw 8 abuts against the rod of the handle 6 to limit the rotation of the handle 6. At the same time, the state of the manual lifting assembly 51 is fixed to prevent its state from being changed by the vibration of the device during normal use. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model provides a printing device for the adhesive surface of synthetic paper material, including a support platform 1. A bidirectional printing base 2, a UV curing device 3, and a laminating device 4 are arranged horizontally in sequence on the top of the support platform 1. A tension manual adjustment mechanism 5 is installed between the UV curing device 3 and the laminating device 4.

[0025] In use, the synthetic paper material is first printed normally on the front side and then on the back side using the bidirectional printing press 2. After printing, it is dried in the UV curing device 3, and then laminated by the laminating device 4. Practical operation shows that the synthetic paper material can be processed stably at a speed of 70 meters per second. There is no displacement when the machine stops, accelerates or decelerates. Moreover, the tension of the synthetic paper material can be adjusted before lamination by the tension manual adjustment mechanism 5 (to tighten it, avoid wrinkles, and ensure tight adhesion) to ensure the lamination effect. When using this device for the adhesive side printing operation, only the following materials need to be prepared: 1. Release paper to separate the raw materials, 2. UV curing printing ink, 3. Laminating base paper, and the process method of direct printing on the adhesive side in reverse.

[0026] In summary, this invention combines the bidirectional printing base 2, the UV curing device 3, and the laminating device 4 together, enabling the synthetic paper material to quickly complete a series of operations from entering the equipment to printing, curing, and laminating along its path. The entire process is efficient and smooth, eliminating the need for a large paper reserve to maintain production, thus eliminating the need for a paper storage rack. Because the UV curing device 3 rapidly transforms the ink from liquid to solid, the adhesive surface acquires non-stick properties in a very short time, eliminating the need for anti-stick rollers to prevent adhesion problems, thereby eliminating the application of anti-stick rollers. Moreover, this invention can directly perform bidirectional printing through the bidirectional printing base 2, thus eliminating the need for a flipping frame and avoiding the frictional damage that a flipping frame may cause to special raw materials.

[0027] By eliminating components such as the paper storage rack, anti-stick roller, and tilting frame, the complexity of the equipment is reduced, and potential malfunctions are eliminated, making operation simpler and more direct, and ensuring more stable equipment operation. In traditional adhesive-coated printing, the paper storage and supply processes of the paper storage rack, the constant monitoring of the anti-stick roller to prevent sticking, and the operation and maintenance of the tilting frame are all quite cumbersome. This device avoids these problems. Regarding saving setup time, traditional adhesive-coated printing, due to its multiple complex components, requires adjusting various parameters such as the paper feeding speed of the paper storage rack, the pressure of the anti-stick roller, and the tilting angle of the tilting frame every time the machine is started or product specifications are changed. This device, with its simplified structure, eliminates the need to adjust these eliminated components, significantly saving setup time. In terms of reducing raw material waste, the physical damage to the adhesive surface caused by the anti-stick roller and the frictional damage to special materials by the tilting frame in traditional printing can lead to defects or even scrap of the raw materials. This device avoids these damages, thereby reducing raw material waste. In terms of cost, the reduction in setup time means increased production efficiency, and the reduction in raw material loss directly lowers material costs. In addition, the elimination of some parts reduces the procurement and maintenance costs of the equipment itself, which together effectively reduces production costs.

[0028] Furthermore, a storage cabinet 9 is fixedly connected to the bottom of the support platform 1. The storage cabinet 9 can support the device at an appropriate height, making it easy to use in conjunction with other devices. The storage cabinet 9 can also be used to store the synthetic paper materials that have been produced. A cast iron counterweight base 10 is fixedly connected to the bottom of the storage cabinet 9. The cast iron counterweight base 10 is made of cast iron material, which has a high density and a greater mass for the same volume, thus providing stable support for the device.

[0029] The manual tension adjustment mechanism 5 includes a manual lifting component 51 that drives the tension roller assembly 52 to move up and down. A buffer component 53 is installed between the manual lifting component 51 and the tension roller assembly 52. ​​In use, by operating the lifting component, the tension roller assembly 52 is raised or lowered, so that it supports the synthetic paper material from below, thereby tensioning the synthetic paper material. In actual production, the tension of the synthetic paper may fluctuate due to various factors, such as changes in the paper roll diameter and uneven quality of the paper itself. The buffer component 53 installed below the tension roller assembly 52 can automatically adjust according to the changes in tension, compensating for tension fluctuations. For example, when the paper tension suddenly increases, the buffer structure is compressed to alleviate the sharp increase in tension; when the paper tension decreases, the buffer component 53 releases the stored energy to maintain a certain tension, keeping the paper tension relatively stable.

[0030] The following is the specific structure of the buffer assembly 53: The buffer assembly 53 includes a groove seat 531 fixed to the head of the manual lifting assembly 51. The inner bottom end of the groove seat 531 is fixed to the lifting plate 533 by a spring 532. The top end of the lifting plate 533 is fixed to the bottom of the tension roller assembly 52 by a vertical rod 534. The two sides of the groove seat 531 are fixedly connected to the guide rail 535. The two sides of the lifting plate 533 are slidably connected to the guide rail 535 by a slider 536.

[0031] Initially, the tension roller assembly 52 is moved to a lower position via the manual adjustment mechanism. After the synthetic paper material is arranged, the buffer assembly 53 is moved upward via the manual adjustment mechanism. The buffer assembly 53 then moves the tension roller assembly 52 upward. When the tension roller assembly 52 moves upward and contacts the bottom of the synthetic paper material, the tension roller assembly 52 is forced to move the vertical rod 534 downward. The vertical rod 534 moves the lifting plate 533 downward, which in turn moves the slider 536 downward. The slider 536 slides downward along the guide rail 535 to maintain the linear movement of the lifting plate 533. The lifting plate 533 compresses the spring 532 downward. Under compression, the spring 532 forms a rebound force, which promotes the tension roller assembly 52 to tighten the synthetic paper material. When the paper tension suddenly increases, the spring 532 is compressed to alleviate the rapid increase in tension. When the paper tension decreases, the spring 532 uses its elasticity to return to its original position, maintaining a certain tension and keeping the paper tension relatively stable.

[0032] The manual lifting assembly 51 is equipped with a handle 6 for easy operation by the operator. A connecting plate 7 is fixedly connected to the manual lifting assembly 51 next to the handle 6, and a screw 8 is threaded inside the connecting plate 7. The operator controls the lifting of the manual lifting assembly 51 by rotating the handle 6 in both directions. After the lifting adjustment is completed, the screw 8 is rotated clockwise. The screw 8 moves along the connecting plate 7 toward the handle 7, so that the end of the screw 8 abuts against the rod of the handle 6 (at this time, the head of the screw 8 abuts against the surface of the connecting plate 7), thereby restricting the rotation of the handle 6 and fixing the state of the manual lifting assembly 51 to prevent its state from being changed by the vibration of the device during normal use.
