[0067] Please refer to Figures 1 - 3 , this embodiment provides a cutter assembly of a laminator, including:

[0068] A tool holder 110, the tool holder 110 includes a tool groove 111 and a guide hole 112 for a laminated part to pass through, the guide hole 112 is perpendicular to the tool groove 111, and the guide hole 112 penetrates through the tool groove 111;

[0069] Longitudinal cutters 120, there are two longitudinal cutters 120, which are respectively arranged on both sides of the opening of the guide hole 112;

[0070] A transverse cutter 130, the transverse cutter 130 is slidably arranged in the tool groove 111, both sides of the cutter body of the transverse cutter 130 are provided with transverse cutting surfaces 131 and rounded corner cutting surfaces 132 are arranged on both sides of the transverse cutting surface 131;

[0071] A driving mechanism, the driving mechanism is connected to the transverse cutter 130, and the driving mechanism is used to drive the transverse cutter 130 to slide back and forth in the tool groove 111, so as to cut the plastic film between two consecutive adjacent laminated parts in the guide hole 112.

[0072] When cutting the plastic film of the laminated part, the laminated part passes through the guide hole 112 on the tool holder 110, and the longitudinal cutters 120 on both sides of the opening of the guide hole 112 cut the plastic film on both longitudinal sides of the laminated part. At the same time, the transverse cutter 130 reciprocates in the tool groove 111 of the tool holder 110 under the drive of the driving mechanism to cut the plastic film between two laminated parts passing through the guide hole 112 horizontally. And transverse cutting surfaces 131 are arranged on both sides of the bottom of the cutter, and rounded corner cutting surfaces 132 are arranged on both sides of the transverse cutting surface 131. When horizontally cutting the plastic film between two laminated parts, the plastic film at the four corners of the laminated part is cut into rounded corners at the same time. Through this cutter assembly, longitudinal cutting, horizontal cutting, and rounded corner cutting of the plastic film on the laminated part can be achieved simultaneously, making the cutting steps of the laminated part more concise, and at the same time making the volume of the laminator more compact.

[0073] Among them, before laminating, the plastic film is in the form of a roll film.

[0074] As Figure 3 shown, both sides of the transverse cutter 130 have transverse cutting surfaces 131, and both ends of the transverse cutting surfaces 131 have rounded cutting surfaces 132. When cutting the plastic film 200 of two laminated parts, the transverse cutting surfaces 131 on both sides perform transverse cutting, and at the same time, the rounded cutting surfaces 132 perform rounded cutting on the two transverse cut corners of the plastic film 200 between two adjacent laminated parts in succession to obtain rounded corners 210. Finally, the laminated parts that have been longitudinally cut, transversely cut, and rounded cut can be obtained. The effect of the laminated parts after cutting is as Figure 4 shown.

[0075] In some embodiments, the tool holder 110 is provided with mounting portions 113 on both sides of the opening of the guide hole 112;

[0076] The longitudinal cutter 120 is detachably mounted on the mounting portion 113.

[0077] By providing the mounting portions 113 on both sides of the opening of the guide hole 112 of the tool holder 110, and the longitudinal cutter 120 is detachably mounted on the mounting portion 113, when the longitudinal cutter 120 is damaged, the replacement of the longitudinal cutter 120 can be realized. Among them, the longitudinal cutter 120 is detachably mounted on the mounting portion 113 by bolts. In other embodiments, the longitudinal cutter 120 can also be detachably mounted on both sides of the guide hole 112 of the tool holder 110 through a clamping structure.

[0078] Please refer to Figure 1 , in some embodiments, the driving mechanism includes:

[0079] A first driving motor 141,

[0080] An eccentric shaft 142, the eccentric shaft 142 is drivingly connected to the first driving motor 141;

[0081] A connecting member 143, one end of the connecting member 143 is disposed on the eccentric shaft 142, and the other end of the connecting member 143 is connected to the transverse cutter 130. The connecting member 143 makes a reciprocating motion as the eccentric shaft 142 rotates.

[0082] The driving mechanism drives the eccentric shaft 142 to rotate by using the first driving motor 141. During the rotation of the eccentric shaft 142, the connecting member 143 can be driven to perform reciprocating motion. During the reciprocating motion of the connecting member 143, the transverse cutter 130 can be driven to reciprocate in the cutter groove 111 of the tool rest 110, thereby realizing the cutting of the plastic film between two over-molded parts by the transverse cutter 130. Wherein, there are two connecting members 143, which are respectively arranged at both ends of the transverse cutter 130. By arranging two connecting members 143 at both ends of the transverse cutter 130 to drive the transverse cutter 130 to cut, the transverse cutter 130 cuts the plastic film between two adjacent over-molded parts more evenly. Wherein, the eccentric shaft 142 has a convex part. During the rotation of the eccentric shaft 142, the convex part on the eccentric shaft 142 drives the connecting member 143 to perform eccentric circular motion, thereby realizing the reciprocating motion of the connecting member 143, and further driving the transverse cutter 130 to reciprocate in the cutter groove 111, so that the transverse cutter 130 cuts the plastic film of the passing over-molded parts.

[0083] In other embodiments, the driving mechanism can also adopt a device that can realize reciprocating motion, such as an electric push rod, a hydraulic cylinder or a pneumatic cylinder, etc.

[0084] In some embodiments, the eccentric shaft 142 is in transmission connection with the first driving motor 141 through a belt 144. Through the belt 144, the first driving motor 141 can drive the eccentric shaft 142 to rotate. In other embodiments, the first driving motor 141 can also be in transmission connection with the eccentric shaft 142 through a gear.

[0085] In some embodiments, the groove shape of the cutter groove 111 is adapted to the tool body shape of the transverse cutter 130. Matching the tool body shape of the transverse cutter 130 with the groove shape of the cutter groove 111 enables the cutter groove 111 to guide and limit the transverse cutter 130, so that the transverse cutter 130 cuts the plastic film between two over-molded parts more accurately.

[0086] In some embodiments, the distance between the two transverse cutting surfaces 131 of the transverse cutter 130 is 2.5 - 4 mm. By setting the distance between the two transverse cutting surfaces 131 of the transverse cutter 130 to 2 - 4 mm, the waste film generated during the cutting of the plastic film between two over-molded parts can be reduced. Preferably, the distance between the two transverse cutting surfaces 131 is 2.5 mm, which can ensure the strength of the tool and its service life while avoiding reducing the waste film.

[0087] Please refer to Figure 5 In another embodiment, a plastic laminating machine includes:

[0088] A heating roller group, the heating roller group includes an upper heating rubber roller 151 and a lower heating rubber roller 152 that are in contact with each other, and a heating device is provided inside the upper heating rubber roller 151 and the lower heating rubber roller 152;

[0089] A conveying roller group, the conveying roller group is used to convey the plastic parts, and the conveying roller group includes a first roller group and a second roller group which are arranged in sequence;

[0090] A second driving motor 180, wherein the second driving motor 180 is transmission-connected to the conveying roller group;

[0091] A cutter assembly, wherein the cutter assembly is disposed between the first roller group and the second roller group, and the cutter assembly is the cutter assembly described above.

[0092] When laminating a document, the folder is sent into the heating roller group between two plastic films, and the air between the plastic film and the document is squeezed by the upper heating rubber roller 151 and the lower heating rubber roller 152. At the same time, the heating device heats the upper heating rubber roller 151 and the lower heating rubber roller 152, so that the plastic film is wrapped around the document to be laminarized, and then sent into the conveying roller group. During the conveying process in the conveying roller group, the cutting knife group between the first roller group and the second roller group cuts the plastic film on the longitudinal sides of the laminating piece and the plastic film between two adjacent laminating pieces to obtain the required laminating piece. When the overmolded piece is cut by the cutter assembly, the overmolded piece passes through the guide hole 112 on the knife holder 110, and the plastic film on the longitudinal sides of the overmolded piece is longitudinally cut by the longitudinal cutters 120 on both sides of the opening of the guide hole 112. At the same time, the transverse cutter 130 reciprocates in the knife groove 111 of the knife holder 110 under the drive of the driving mechanism to transversely cut the plastic film between the two overmolded pieces passing through the guide hole 112, and transverse cutting surfaces 131 are provided on both sides of the bottom of the cutter and rounded cutting surfaces 132 are provided on both sides of the transverse cutting surface 131. When the plastic film between the two overmolded pieces is transversely cut, the plastic film at the four corners of the overmolded piece is rounded at the same time. The cutter assembly can simultaneously realize longitudinal cutting, transverse cutting and rounded cutting of the plastic film on the overmolded piece, making the cutting steps of the overmolded piece simpler and making the volume of the overmolding machine more compact.

[0093] like Figures 3 - 4 As shown, the transverse cutter 130 has transverse sections 131 on both sides, and the two ends of the transverse sections 131 have rounded sections 132. When cutting the plastic film 200 of two overmolded parts, the transverse sections 131 on both sides are cut transversely, and at the same time, the rounded sections 132 at both ends round the two corners of the cross-section of the plastic film 200 between two consecutive adjacent overmolded parts to obtain rounded corners 210. Finally, overmolded parts that have been cut longitudinally, transversely and rounded can be obtained.

[0094] In some embodiments, the heating device is a heating lamp 153. The upper heating rubber roller 151 and the lower heating rubber roller 152 are heated by the heating lamp 153, so that the plastic film is wrapped around the document. In other embodiments, the heating device can also be a heating wire, a heating rod, etc.

[0095] In some embodiments, the second roller group includes a first rubber roller 162 and a second rubber roller 161 that are in contact with each other, and the first rubber roller 162 is drivingly connected to a second driving motor 180;

[0096] The third roller group includes a third rubber roller 171 and a fourth rubber roller 172 that are in contact with each other, and the third rubber roller 171 is drivingly connected to the second rubber roller 161.

[0097] The second driving motor 180 drives the first rubber roller 162 in the second roller group to rotate. As the first rubber roller 162 rotates, it drives the second rubber roller 161 to rotate. The rotation of the first rubber roller 162 and the second rubber roller 161 pulls and conveys the workpieces passing through the second roller group. Since the second rubber roller 161 is drivingly connected to the third rubber roller in the third roller group, the rotation of the second rubber roller 161 also drives the third rubber roller 171 to rotate, enabling the third roller group to also convey the workpieces passing through, thus realizing the conveyance of the workpieces passing through.

[0098] In some embodiments, the first driving motor 141 and the second driving motor 180 are electric motors. The first driving motor 141 and the second driving motor 180 can be electric motors to drive the transverse cutter 130 assembly and the conveying roller group. In other embodiments, the first driving motor 141 and the second driving motor 180 can also be pneumatic motors or hydraulic motors.

[0099] Different from the prior art, in the above technical solution, when cutting the plastic film of the workpiece passing through, the workpiece passing through passes through the guide hole 112 on the tool rest 110, and the longitudinal cutters 120 on both sides of the opening of the guide hole 112 cut the plastic film on both longitudinal sides of the workpiece passing through. At the same time, the transverse cutter 130 reciprocates in the cutter groove 111 of the tool rest 110 under the drive of the drive mechanism to transversely cut the plastic film between two workpieces passing through the guide hole 112. A transverse cutting surface 131 is provided on both sides of the bottom of the cutter, and rounded cutting surfaces 132 are provided on both sides of the transverse cutting surface 131. The cutter assembly can simultaneously perform longitudinal cutting, transverse cutting, and rounded cutting on the plastic film on the workpiece passing through, making the cutting steps of the workpiece passing through more concise, and at the same time making the volume of the laminator more compact.

[0100] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structural or equivalent process substitutions or modifications made based on the substantial concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as those directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included within the patent protection scope of this application.
