Description
Technical Field
[0001] The utility model belongs to the technical field of laminating machines, and in particular relates to an energy-saving internal heating laminating machine. Background Art
[0002] Laminator is also called laminator, glue machine and laminating machine. It is mainly composed of drive system, heating temperature control system, operation control panel, front and rear rubber rollers and other components. It is a special equipment for laminating photos or documents. Laminating uses hot pressing to laminate thin sheets of paper and other thin items, and the plastic software is bonded by heated pressure rollers.
[0003] The existing laminator mainly includes a laminator shell and a heating pad arranged inside the laminator shell, two heating conveyor rollers and two conveyor rollers. The heating pad heats the heating conveyor rollers, and then the card is inserted between the two heating conveyor rollers to heat the cardboard, and then output to the outside through the two conveyor rollers.
[0004] However, there are several problems when the plastic shell is plasticized;
[0005] 1. When the cardboard is laminated, dust will stick to it. When the dust enters the heated conveyor roller and the conveyor roller, the dust will stick to the heated conveyor roller and the conveyor roller. When heated, the dust will cause uneven heating of the cardboard. At this time, wrinkles and bubbles will appear on the cardboard, causing damage to the cardboard.
[0006] 2. The rubber roller of the laminator will generate static electricity when laminating materials. Static electricity will also absorb dust, causing the rubber roller to stick to the dust. Similarly, dust will cause uneven heating of the cardboard, causing wrinkles and bubbles to appear on the cardboard.
[0007] 3. The existing heating system does not have a heat preservation effect. After the rubber roller is heated, the heat generated is directly dissipated in the air, resulting in heat waste.
[0008] To this end, we have proposed an energy-saving internal heating laminator, which can keep the rubber roller dust-free and heat it evenly during operation, and at the same time set up a heat-insulating shell to achieve energy-saving effects. Utility Model Content

[0029] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0030] like Figure 1-5 As shown, the technical solution adopted by the utility model is as follows: an energy-saving internal heat laminator comprises a laminator shell 1, inside which are arranged a heat preservation shell 2, a polygonal turning sheet 3 and two groups of first rubber rollers 4 from left to right, and outside the two groups of first rubber rollers 4 are arranged first impurity removal rollers 5 which are in contact with the first rubber rollers 4;
[0031] Two groups of heating tubes 6, two groups of second rubber rollers 7 and two groups of first impurity removal rollers 5 are rotatably arranged on the inner wall of the heat preservation shell 2. The two groups of heating tubes 6 are fitted with the two groups of second rubber rollers 7. The outer sides of the two groups of second rubber rollers 7 are provided with second impurity removal rollers 8 fitted therewith.
[0032] In order to better remove impurities from the first rubber roller 4 and the second rubber roller 7, the first impurity removing roller 5 and the second impurity removing roller 8 usually use highly elastic rubber or silicone, because these materials have good wear resistance and anti-aging properties and can maintain their cleaning effect for a long time.
[0033] The friction coefficient is an indicator of the resistance when one material surface slides against another material surface. In order to effectively remove dust, the surface materials of the first and second cleaning rollers 5 and 8 need to have a high friction coefficient, but at the same time, it is also necessary to ensure that the first and second rubber rollers 4 and 7 are not damaged. Usually, the friction coefficients of the first and second cleaning rollers 5 and 8 are between 0.35 and 0.45, which can take into account both the dust removal effect and the need to protect the rubber rollers.
[0034] Shape: The first and second cleaning rollers 5 and 8 are usually cylindrical in shape, and their surfaces may have some textures or raised designs, which can increase the contact area with the surfaces of the first and second rubber rollers 4 and 7 and improve the dust removal effect.
[0035] Operation principle: The first and second cleaning rollers 5 and 8 remove dust mainly by contacting with the first rubber roller 4 and the second rubber roller 7. When the first and second cleaning rollers 5 and 8 contact with the first and second rubber rollers 4 and 7, the dust is scraped off the surface of the first and second rubber rollers 4 and 7 due to the friction between the two, and is adsorbed on the surface materials of the first and second cleaning rollers 5 and 8. Then, during the rotation of the first and second cleaning rollers 5 and 8, the dust adsorbed on their surfaces will fall to the bottom of the plastic shell due to the friction and gravity.
[0036] First, when the first and second cleaning rollers 5 and 8 come into contact with the first and second rubber rollers 4 and 7, due to the friction force, dust is scraped off the surfaces of the first and second rubber rollers 4 and 7 and adsorbed on the surface materials of the first and second cleaning rollers 5 and 8. As the first and second cleaning rollers 5 and 8 rotate, the adsorbed dust moves with the movement of the surface materials of the first and second rubber rollers 4 and 7.
[0037] Secondly, since the surface materials of the first and second impurity-removing rollers 5 and 8 have a certain degree of roughness, the adhesion of dust on the surfaces of the first and second impurity-removing rollers 5 and 8 is weakened, and it is easier to be pulled off the surfaces of the first and second impurity-removing rollers 5 and 8 by gravity. At the same time, if the surface materials of the first and second impurity-removing rollers 5 and 8 have a certain degree of adsorption, such as fluff, etc., this will also enhance the adhesion of dust on the surfaces of the first and second impurity-removing rollers 5 and 8, making it easier to remove.
[0038] Finally, when the dust reaches the bottom of the overmolding shell as the first and second impurity removing rollers 5 and 8 rotate, the dust will slide off the surfaces of the first and second impurity removing rollers 5 and 8 and fall to the bottom of the overmolding shell 1 due to gravity.
[0039] A fixing frame is arranged on the outer side of the plastic shell 1, and a motor 10 is arranged on the fixing frame. A first gear 11 is installed on the output end of the motor 10. A second gear 12 is sleeved on the rotating shafts of the two groups of first rubber rollers 4, a third gear 13 is sleeved on the rotating shafts of the two groups of second impurity removing rollers 8, a fourth gear 14 is sleeved on the rotating shafts of the two groups of heating tubes 6, a fifth gear 15 is sleeved on the rotating shafts of the two groups of second rubber rollers 7, and a sixth gear 16 is sleeved on the rotating shafts of the two groups of first impurity removing rollers 5. The outer side of the first gear 11 is meshed with one of the second gears 12 and one of the fifth gears 15, the two second gears 12 are meshed with the two sixth gears 16, the two fifth gears 15 are meshed with the two third gears 13, and the two fifth gears 15 are meshed with the fourth gear 14.
[0040] With such an arrangement, the first gear 11 drives one of the second gears 12 and one of the fifth gears 15 to rotate, the fifth gear 15 drives the third gear 13 to rotate, and at the same time drives the fourth gear 14 to rotate, so that the second impurity-removing roller 8 removes impurities on the second rubber roller 7, thereby preventing uneven heat transfer due to the action of impurities, causing wrinkles and bubbles in the jammed paper, and at the same time, the second gear 12 drives the sixth gear 16 to rotate, so that the first impurity-removing roller 5 removes impurities on the first rubber roller 4, thereby preventing wrinkles and bubbles in the jammed paper due to the action of impurities.
[0041] It should be noted that the first and second impurity removing rollers 5 and 8 can be disassembled from the plastic shell 1. This connection can be achieved by snap-fitting. The advantage of this is that the first and second impurity removing rollers 5 and 8 can be disassembled for cleaning.
[0042] Furthermore, the two groups of first rubber rollers 4, the second impurity removing rollers 8, the two groups of heating tubes 6, the two groups of second rubber rollers 7 and the two groups of first impurity removing rollers 5 are all sleeved on the rotating shaft, and both ends of the rotating shaft pass through the plastic shell. This arrangement can make the two groups of first rubber rollers 4, the second impurity removing rollers 8, the two groups of heating tubes 6, the two groups of second rubber rollers 7 and the two groups of first impurity removing rollers 5 rotate on the plastic shell 1, and rotate by driving.
[0043] Furthermore, the plastic shell 1 is made of plastic that can be disassembled and spliced, and it can also be made of iron sheet.
[0044] Furthermore, both the overmolded housing 1 and the polygonal flipping sheet 3 are provided with through slots 9 for allowing jammed paper to enter. Jammed paper can enter through the through slots 9 and can be connected at the same time to prevent paper jams.
[0045] Furthermore, a heat-insulating layer is provided on the inner wall of the heat-insulating shell 2, which can prevent heat from dissipating quickly, eliminating the need for frequent heating and achieving energy-saving effects.
[0046] Furthermore, a temperature sensor (not shown in the figure) is provided inside the plastic shell 1, and the temperature sensor is fitted with the insulation shell 2. The temperature inside the insulation shell 2 can be sensed by the temperature sensor. In this way, the heating tube 6 can be controlled to work or stop working, thereby eliminating the need for frequent heating and achieving energy-saving effects.
[0047] It should be noted that the temperature sensor is a necessary component inside the laminator, which is not marked here. Its installation method and operation method are all existing technologies and will not be described in detail here.
[0048] Furthermore, heating plates are arranged inside the two groups of heating tubes 6, and the heating tubes 6 are heated by the heating plates.
[0049] It should be noted that the heating tube 6 of the utility model can rotate, and its heat can be evenly distributed on the second rubber roller 7 to improve its heating effect on the cardboard. At the same time, a small collector ring can be installed on the heating tube 6. The collector ring can prevent the wire of the heating plate from being damaged when rotating. The collector ring is also called a conductive ring, slip ring, collector ring, and collector ring. It is a conductive metal ring that contacts the brush and allows the current to flow from one part of the circuit to another part through sliding contact. This can ensure that the heating tube 6 can rotate and prevent the wire from being damaged.
[0050] Furthermore, the first rubber roller 4 and the second rubber roller 7 are hollow structures with a vacuum chamber inside. This not only reduces the weight, but also slows down the flow rate of heat when it enters the vacuum chamber, thereby achieving a heat preservation effect. There is no need for frequent heating, thereby achieving an energy-saving effect.
[0051] Furthermore, a heat dissipation hole is provided on the top of the laminating shell 1, through which the heat inside the laminating machine can be quickly dissipated.
[0052] Optionally, a cooling fan may be added to improve the cooling performance.
[0053] It should be noted that the cooling fan is a prior art, and its installation method and operating principle are both prior art, and will not be described in detail here.
[0054] Furthermore, the distance between the two heating tubes 6 is greater than the thickness of the card joint, which means that they do not come into contact with the card paper, thus preventing the card paper from being damaged due to high temperature.
[0055] Furthermore, the distance between the two first rubber rollers 4 and the second rubber roller 7 needs to match the thickness of the clamping, so that the first rubber roller 4 and the second rubber roller 7 can be transported smoothly, thus preventing the paper from getting stuck.
[0056] The working principle of the utility model is as follows: firstly, the motor 10 drives the first gear 11 to rotate, and the first gear 11 drives the second gear 12, the third gear 13, the fourth gear 14 and the fifth gear 15 to rotate, and the second impurity removing roller 8 removes the impurities on the second rubber roller 7, and the first impurity removing roller 5 removes the impurities on the first rubber roller 4, so that the first rubber roller 4 and the second rubber roller 7 can maintain a state without impurities when working, and will not cause uneven heat transfer during laminating, resulting in bubbles and paper jams, and then the paper jams enter the laminating shell 1 through the through groove 9. At this time, the state of the paper jam is between the two second rubber rollers 7, and the paper jams enter the through groove 9 on the polygonal turning plate through the transportation of the second rubber roller 7 for connection, which will not cause paper jams, and then the paper jams are transported to the outside through the first rubber roller 4. At the same time, the cleaned impurities fall on the bottom of the laminating shell 1. When cleaning is needed, it is only necessary to open the laminating shell 1 to clean the dust, and there is no need to disassemble the first rubber roller 4 and the second rubber roller 7.
[0057] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
