[0027] In the present application, the technical features described in an open manner include closed technical solutions composed of the listed features, and also include open technical solutions containing the listed features.

[0028] In one embodiment, a laminator is provided, comprising a housing, a cover plate and a cutting assembly, wherein the housing is provided with a receiving groove, the cutting assembly is arranged on one side of the cover plate, and the side of the cover plate close to the cutting assembly is used to cover the receiving groove, and the cutting assembly is accommodated in the receiving groove. When the cover plate is covered in the receiving groove, the cutting assembly is accommodated in the receiving groove, thereby accommodating the cutting assembly, and at the same time, the receiving groove is covered by the cover plate, and the accommodating process is simple and quick. When the cutting assembly needs to be used, the cover plate can be opened to remove the cutting assembly from the receiving groove, and the cover plate can provide a firm working surface for the cutting assembly and the paper, thereby facilitating the cutting assembly to process the paper.

[0029] Specifically, Figure 1 and Figure 2 As shown, a laminator 10 is provided, comprising a housing 100, a cover plate 200 and a cutting assembly 300. The housing 100 is provided with a receiving groove 101, and the cutting assembly 300 is arranged on one side of the cover plate 200. The side 201 of the cover plate 200 close to the cutting assembly is used to cover the receiving groove 101, and the cutting assembly 300 is accommodated in the receiving groove 101. Specifically, the side 201 of the cover plate 200 close to the cutting assembly is covered at the notch of the receiving groove 101, so as to cover the receiving groove 101 and accommodate the cutting assembly 300. For example, the cover 200 is covered on the housing 100 near the receiving groove 101. Specifically, the cover 200 is covered on the edge of the receiving groove 101 to achieve that the cover 200 is covered on the receiving groove 101. For another example, the wall of the receiving groove 101 is protruded with a boss 101, and the cover 200 is covered on the boss 101, thereby covering the receiving groove 101.

[0030] Specifically, the cover plate can be covered on the outer edge of the receiving groove, or on the wall surface of the receiving groove, so as to cover the cover plate on the receiving groove.

[0031] like Figure 3 As shown, the cover plate 200 matches the notch of the receiving groove 101 to close the receiving groove 101, so that the cutting assembly 300 can be completely hidden, making the outer surface of the plastic packaging machine 10 more concise and protecting the cutting assembly 300. Figure 4In this embodiment, the cutting assembly 300 is completely received in the receiving groove 101, and a boss 120 is provided on the wall of the receiving groove 101. A side 201 of the cover plate 200 close to the cutting assembly is used to cover the boss 120, and the other side of the cover plate 200 is used to smoothly transition with the outer side of the housing 100. The boss 120 is protruding from the wall of the receiving groove 101 and is stepped with the outer side of the housing 100. The height from the boss 120 to the bottom of the receiving groove 101 is lower than the height from the outer side of the housing 100 to the bottom of the receiving groove 101. Specifically, the thickness of the cover plate 200 is between one side 201 of the cover plate 200 close to the cutting assembly and the other side 202. The thickness of the cover plate 200 is equal to the distance from the boss 120 to the housing 100. When the cover plate 200 is covered on the boss 120, the side 201 of the cover plate 200 away from the cutting assembly is flush with the cover plate 200, thereby achieving a smooth transition. In another embodiment, the outer side of the housing has a streamlined structure, and the side of the cover plate away from the cutting assembly is set to a structure corresponding to the outer side of the housing, thereby achieving a smooth transition. The smooth transition structure between the cover plate and the housing can be set according to actual conditions. The smooth transition is to avoid the height difference between the cover plate and the outer side of the housing as much as possible, so that from the appearance, the cover plate and the outer side of the housing are connected as one.

[0032] It is worth mentioning that the laminating machine 10 in the present application has both laminating and cutting functions. For example, a laminating assembly is provided in the laminating machine, and the laminating assembly is used to laminat e papers and photos. The structure of the laminating assembly will be described in detail in the following embodiments, and will not be described in detail in this embodiment. The cutting assembly is used to cut and trim papers and photos. In this embodiment, the cutting assembly 300 provided on the cover plate 200 can be disassembled from the housing 100, so that the laminating machine can be disassembled into two separate parts for use. For example, the laminating assembly on the housing can be used as a laminating machine alone, and the cutting assembly on the cover plate can be used as a cutting machine alone after being disassembled from the housing. In other words, the cutting assembly disassembled from the housing can cut papers and photos alone without the need to cooperate with the laminating assembly of the housing. In this way, the convenience of use can be greatly improved, and the volume is small after disassembly, which is easy to carry.

[0033] In addition, in this embodiment, when the cutting assembly is installed on the casing, there are two ways to install the cutting assembly: one is the use state, and the other is the hidden state. Among them, the use state refers to that the cutting assembly is placed upright, the cover plate is installed on the casing, and the receiving groove is closed so that the cutting assembly is located at the top of the casing, so that the cutting assembly can be used in conjunction with the plastic packaging assembly. The hidden state refers to that the cutting assembly is placed inverted, the cover plate is installed on the casing, and the receiving groove is closed so that the cutting assembly is located in the receiving groove, so that the cutting assembly is hidden, and the top surface of the plastic packaging machine is kept flat, which can be beneficial to the packaging and transportation of the plastic packaging machine. Packaging the plastic packaging machine in this way can effectively save 40% of packaging materials.

[0034] like Figure 5 and Figure 6 As shown, in this embodiment, the side 202 of the cover plate 200 facing away from the cutting assembly is also used to cover the receiving groove 101, so that the cutting assembly 300 protrudes from the receiving groove 101. In this way, the cover plate 200 covers the receiving groove 101 and obtains the support of the housing 100, and the cutting paper is protruded from the receiving groove 101, which saves space for arranging the cutting assembly 300 and facilitates the cutting assembly 300 to be closer to the user, facilitating the operation of cutting paper. Specifically, the side 202 of the cover plate 200 facing away from the cutting assembly is also used to cover the boss 120, so that the cutting assembly 300 protrudes from the housing 100.

[0035] In the above embodiment, the cover is installed on the casing by placing the cover on the boss, and because the shape of the cover matches the shape of the receiving groove, the cover can be firmly placed on the casing, and the cutting assembly can be firmly installed regardless of whether it is upright or inverted. In some other embodiments, the cover plate can also be installed on the casing in other ways: in one embodiment, a sliding structure is provided on the surface of the casing, and the cover plate is slidably provided on the sliding structure. The cover plate is clamped on the sliding structure so that the cover plate slides on the sliding structure to achieve connection between the cover plate and the casing. For example, a sliding groove is provided on the top of the casing, and limiting grooves are provided on the side walls on both sides of the sliding groove so that the cross-sectional shape of the sliding groove and the limiting groove is a "convex" shape. The cover plate is provided with a sliding protrusion, and the shape of the sliding protrusion matches the shape of the sliding groove and the limiting groove, which is a "convex" shape. During installation, the sliding protrusion is inserted into one end of the sliding groove so that the sliding protrusion slides along the sliding groove, thereby installing the cover plate in an appropriate position. The limiting groove can effectively limit the sliding protrusion to prevent the sliding protrusion from falling off the sliding groove. Similarly, the installation by sliding can also be suitable for installing the cutting assembly in an upright or inverted manner. When the cutting assembly is inverted, the cutting assembly can also slide into the receiving groove as the cover plate slides. In this embodiment, an entrance connected to the receiving groove can be opened on one side of the casing, and the edge of the entrance is rotatably connected to a sealing plate, so that the cutting assembly can slide along the entrance into the receiving groove. After the cutting assembly slides into the receiving groove, the sealing plate is rotated to close the entrance, so that the cutting assembly can be closed and hidden.

[0036] It is worth mentioning that the cover plate can also be connected to the shell by other sliding methods. In addition, a snap or locking structure can be provided to lock or snap the cover plate that has been slid to the appropriate position.

[0037] In one embodiment, the cover is hinged to the housing, and during the hinged connection of the cover, the cutting assembly can be accommodated in the cutting assembly or arranged outside the housing. In this embodiment, the cover adopts a hidden structure similar to that of a traditional sewing machine, and the cutting assembly can be rotated into the receiving groove or to the top surface of the housing as the cover rotates.

[0038] In one of the embodiments, one side of the cover is hinged to the casing via a hinge structure, the cutting assembly is disposed in the middle of the cover and the distance from the cutting assembly to the hinge axis is smaller than the distance from the cover to the hinge axis, thus avoiding interference between the cutting assembly and the casing.

[0039] In one embodiment, the cutting assembly includes a paper cutter, and the receiving groove is also used to receive a corner rounder and / or a paper hole punch. In this embodiment, the receiving groove is also used to receive a corner rounder and a paper hole punch. The paper cutter is used to cut objects such as paper and plastic, for example, to cut the edge of a paper, or to cut the corner of a paper. The corner rounder is used to round the corners of a paper to trim the corners of the paper. The paper hole punch can punch holes in objects such as paper and plastic to facilitate binding. After receiving the corner rounder and the paper hole punch, the laminator's ability to process paper is further enriched. In one embodiment, the receiving groove is deeper on both sides of the casing, and one of the deeper sides of the receiving groove is used to receive the paper cutter, and the other deeper side is used to receive the stacked corner rounder and paper hole punch. The middle part of the receiving groove is shallower and is used to accommodate the guide rail for the cutter to slide. The casing includes a plastic overpass channel, which is symmetrical with the receiving groove about the bottom of the receiving groove. The shallow middle part of the receiving groove is also conducive to avoiding the plastic overpass channel, giving the plastic overpass channel enough opening space.

[0040] like Figure 6 and Figure 7 As shown, in one embodiment, the cutting assembly 300 includes a guide rail 310 and a movable member 320, at least one end of the guide rail 310 is connected to the cover plate 200, and a paper feeding channel 203 is formed between the guide rail 310 and the cover plate 200, and the movable member 320 is slidably disposed at a position of the guide rail 310 away from the paper feeding channel 203, and one of the cover plate 200 and the movable member 320 is provided with a blade 323, and the blade 323 extends into the paper feeding channel 203 and abuts against the other of the cover plate 200 and the movable member 320. In one embodiment, the movable member 320 is provided with a blade 323, and the blade 323 is movably abutted with the cover plate 200. After the paper is placed on the cover plate 200, the blade 323 slides on the guide rail 310 and passes over the surface of the cover plate 200, thereby cutting the paper on the cover plate 200. In another embodiment, the cover plate is provided with a long strip blade, and when the movable member slides on the guide rail, the paper is pressed against the blade, and the blade cuts the paper. In this way, the paper can be cut.

[0041] like Figure 8As shown, in one embodiment, the laminating machine 10 further includes a laminating assembly 500, and a laminating passage 501 separated from the receiving groove 101 is provided in the housing 100, and the laminating assembly 500 is arranged in the laminating passage 501. Specifically, the laminating assembly 500 includes at least two correspondingly arranged heating rollers 520. The laminating can be completed by sandwiching the paper between two plastic sheets and placing it between the two heating rollers of the plastic assembly. Among them, the receiving groove 101 and the laminating passage are separated from each other, so as to avoid mutual interference between the laminating assembly and the cutting assembly 300, and also to avoid impurities that may exist in the cutting assembly 300 from falling into the laminating assembly.

[0042] In one embodiment, a ruler portion is provided on a side of the cover plate close to the cutting assembly and / or the housing. For example, a ruler portion is provided on a side of the cover plate close to the cutting assembly. Figure 6 As shown, in this embodiment, the housing 100 is provided with a ruler portion 400. Specifically, the housing 100 is provided with a ruler portion 400 near the receiving slot 101. The ruler portion is used to measure the paper, which is helpful for the user to perform cutting processing according to the specific size of the paper.

[0043] like Fig. 9 As shown, in this embodiment, the movable member 320 includes a housing 324, a rotating disk 321 and a plurality of circular knives 322, wherein the rotating disk 321 is rotatably disposed on the housing 324, the circular knives 322 are arranged at intervals along the circumference of the rotating disk 321, and each of the circular knives 322 is rotatably connected to the rotating disk 321, wherein each of the circular knives 322 includes a blade 323, and the shapes of the blades 323 are arranged differently. As the circular knives 322 rotate, the blades 323 of the circular knives 322 can roll along the paper, and different blades 323 can cut patterns of different shapes on the paper, and the rotating disk 321 can selectively drive each of the circular knives 322 toward the cover plate 200. For example, a smoothly disposed blade can cut the paper along a straight line. For another example, a blade with a wavy pattern can cut the edge of the paper into a wavy shape. For another example, a sawtooth blade can draw a dotted line along the paper, and the paper can be easily torn apart along the dotted line when it needs to be torn apart.

[0044] When the paper is sandwiched between two plastic sealing sheets and then sent into the plastic passage 501, the two heating rollers 520 of the plastic sealing assembly 500 can heat-press the plastic sealing sheets and make the two plastic sealing sheets clamp the paper. The cover plate 200 is taken out of the receiving groove 101 and turned over to cover the boss 120, so that the cutting assembly 300 can stand on the outside of the housing 100, and the paper to be cut is sent into the paper feeding passage 203. The paper is measured and the position of the paper on the cover plate 200 is adjusted according to the marking part 400, and then the movable part 320 is slid along the guide rail 310, so that the circular knife 322 of the movable part 320 can roll on the cover plate 200 and cut the paper. After cutting, the cover plate 200 can be turned over again and covered in the receiving groove 101, so as to accommodate the cutting assembly 300 and prevent the cutting assembly 300 from being exposed, thereby making the outer surface of the plastic sealing machine 10 simple and protecting the cutting assembly 300.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
