Description

TECHNICAL FIELD

[0001] The present application relates to the paperboard processing technical field, specifically, relate to a paperboard opening laminating device. BACKGROUND

[0002] Paperboard is also called board paper. It is a thick paper sheet composed of fibers interwoven with each other, which is processed from various pulp. Paperboard is usually distinguished from paper by basis weight and thickness. Generally, paperboard with basis weight exceeding 250g / m2 and thickness greater than 0.5mm is called paperboard.

[0003] Paperboard is often used as a product such as a packaging box. Sometimes, a hole is opened on the paperboard to facilitate buckling. The paperboard cannot be directly used as a packaging box, and a layer of surface paper must be added to both end faces of the hard base paper. The surface paper cannot be in a complete state at the opening position, and a similar opening must also be provided. In order to avoid the edge from being raised, the surface paper must be folded and laminated to the other end of the paperboard at the edge during packaging. Therefore, the surface paper at the opening position of the paperboard is usually divided into several areas by several cuts, and then the surface paper of each area is folded and laminated to the state of the paperboard. The existing paperboard opening laminating process usually uses manual operation, which is time-consuming, labor-intensive and low in efficiency. SUMMARY

[0004] In summary, in order to overcome the shortcomings of the prior art, the present application provides a paperboard opening laminating device with higher efficiency.

[0005] To achieve the above object, the present application provides the following technical scheme: a paperboard opening laminating device, comprising a processing table, the processing table is provided with a folding edge boss, the processing table is provided with an air inlet groove communicating with the folding edge boss, and the outer wall of the folding edge boss is provided with an air outlet channel communicating with the air inlet groove.

[0006] In this way, when in use, the surface paper is first attached to the opening paperboard. Then, the paperboard is moved to the folding edge boss by a mechanical hand or manually, or the paperboard is conveyed to the processing table by a conveying mechanism such as a conveying belt, and then the folding edge boss is raised from the bottom of the opening. The folding edge boss will adapt to the shape of the opening, so that when the folding edge boss enters the opening, the surface paper at the opening position, which is divided into multiple areas, will be lifted by the folding edge boss to be laminated to the side surface of the folding edge boss. Then, the air pipe is connected to the air inlet groove, and air is blown into the air inlet groove. Then, the air flow in the air inlet groove is blown towards the surface paper that needs to be folded and laminated to the side surface of the folding edge boss through the air outlet channel. In this way, the surface paper at each side edge can be blown down at the same time, so as to be laminated to the other surface of the paperboard. The efficiency is higher. When the folding edge boss is raised, the paperboard can be pressed or manually limited in height by a tool for easy use.

[0007] Further, one end of the air outlet channel towards the outside of the folding edge boss is inclinedly arranged towards the end surface of the processing table.

[0008] In this way, the air flow sent by the air outlet channel will blow towards the paperboard, so that the paperboard can be bent and attached more tightly.

[0009] Further, the opening of the air inlet groove is located at the bottom of the processing table, and the top of the air inlet groove is conical.

[0010] In this way, when the air pipe sends the air flow into the air inlet groove, the air flow first hits the top of the air inlet groove and then hits the top surface, and since the top surface is conical, the air flow can more easily flow along the inclined surface to the air outlet channel on the side.

[0011] Further, the top of the edge folding boss is a cone.

[0012] In this way, the cone is more easily inserted into the paperboard, and only needs to be roughly positioned and pressed into the natural position along the inclined surface of the cone to guide it to the accurate position.

[0013] Further, the top of the edge folding boss is provided with a pressing surface.

[0014] In this way, the edge folding boss is prismatic, and the top is not sharp, so that when it is inserted, the pressing surface contacts the mounting film, and the mounting film is not damaged, and it is safer.

[0015] Further, the device further comprises a pressing mechanism, the pressing mechanism comprising a pressing frame, a first driving machine and a first pressing plate, the first driving machine being connected to the pressing frame, the first driving machine driving the first pressing plate to reciprocate towards the edge folding boss at the top of the edge folding boss, and the first pressing plate being provided with a first clearance hole adapted to the edge folding boss.

[0016] In this way, after the paperboard is blown down by the air flow of the air outlet channel, the first driving machine on the pressing frame drives the first pressing plate to press down, and since the first pressing plate is provided with the first clearance hole, the first pressing plate is in the shape of a ring around the paperboard opening, and after the pressing plate in this shape is pressed down, it can simultaneously press the bent paperboard, further pressing it to make it more tightly attached, the first driving machine can use an electric push rod or a gas cylinder hydraulic cylinder, and other driving machines in this application can also be selected.

[0017] Further, the pressing mechanism further comprises a second driving machine and a second pressing plate, the second driving machine being connected to the pressing frame, and the second driving machine driving the second pressing plate to reciprocate towards the processing table at the top of the edge folding boss.

[0018] In this way, before the device bends and attaches the paperboard, the second driving machine will control the second pressing plate to press down and press the paperboard tightly on the processing table, so that the paperboard can be stabilized and will not shake and swing during the attachment process.

[0019] Further, the second pressing plate is provided with a second accommodating hole matched with the first pressing plate, and the first pressing plate is located in the second accommodating hole.

[0020] In this way, the second pressing plate can press the paperboard around the opening, mainly stabilizing the opening part, and the stabilizing effect is more accurate.

[0021] Further, the bottom of the second pressing plate is provided with an exhaust groove communicated with the outer wall and the second accommodating hole.

[0022] In this way, the exhaust passage on the folding protrusion of the second pressing plate can blow air to the folding surface of the paper after pressing the paperboard, and the blown air can be sent out through the exhaust groove at the bottom of the second pressing plate, so as not to be blocked in the second accommodating hole and not to be backflushed to the surface paper.

[0023] Further, the folding protrusion is a polygonal protrusion.

[0024] In this way, the polygonal protrusion is matched with the polygonal opening, and the surface paper is cut at the opening part to form a cut opening matched with the shape of the opening, such as X-shaped for a quadrilateral, Y-shaped for a triangle, etc. Each area of the divided surface paper forms a triangle, and the bottom side of the triangle is parallel to the polygonal protrusion, so that the folding effect is better and the surface paper is more closely attached to the bottom paper.

DETAILED DESCRIPTION

[0034] The specific embodiments are only an explanation of the embodiments, which are not a limitation of the embodiments. Those skilled in the art can make modifications to the embodiments according to needs after reading the specification, but as long as the modifications are within the scope of the claims of the embodiments, they are protected by the patent law.

[0035] Referring to the drawings, the present application provides the following technical solutions: a paperboard 3 opening fitting device, comprising a processing table 1, the processing table 1 is provided with a flanging boss 101, the processing table 1 is provided with an air inlet groove 102 communicating with the flanging boss 101, and the outer wall of the flanging boss 101 is provided with an air outlet channel 103 communicating with the air inlet groove 102.

[0036] In this way, when in use, the face paper 4 is first attached to the opening paperboard 3, then the paperboard 3 is moved to the flanging boss 101 by a mechanical hand or manually, or the paperboard 3 is conveyed to the processing table 1 by a conveying mechanism such as a conveying belt, and then the flanging boss 101 is raised from the bottom of the opening, and the flanging boss 101 is adapted to the shape of the opening, so that when the flanging boss 101 enters the opening, the face paper 4 in each area of the opening is lifted by the flanging boss 101 to attach to the side of the flanging boss 101, then the air pipe is connected with the air inlet groove 102, air is blown into the air inlet groove 102, and then the airflow in the air inlet groove 102 is blown towards the face paper 4 on the side of the flanging boss 101 which needs to be bent and attached, so that the face paper 4 on each side is blown down at the same time, and the other side of the face paper 4 is attached to the paperboard 3, which is more efficient. When the flanging boss 101 is raised, the paperboard 3 can be manually pressed or limited in height for easy use.

[0037] Preferably in the embodiment, one end of the air outlet channel 103 towards the outside of the flanging boss 101 is inclinedly arranged towards the end face of the processing table 1.

[0038] In this way, the airflow sent by the air outlet channel 103 is blown towards the paperboard 3, so that the face paper 4 is bent and attached more tightly.

[0039] Preferably in the embodiment, the opening of the air inlet groove 102 is located at the bottom of the processing table 1, and the top of the air inlet groove 102 is conical.

[0040] In this way, when the air duct sends the airflow into the air inlet groove 102, the airflow first hits the top of the air inlet groove 102 and impacts the top surface. Since the top surface is conical, the airflow is more likely to flow along the inclined surface to the air outlet channel 103 on the side.

[0041] In this embodiment, the top of the flange boss 101 is preferably a cone.

[0042] In this way, the cone is more likely to be aligned with the insertion of the paperboard 3, and only needs to be roughly positioned and pressed into the natural return along the inclined surface of the cone to guide it to the correct position.

[0043] In this embodiment, the top of the flange boss 101 is provided with a pressing surface 1011.

[0044] In this way, the flange boss 101 will be a prism, and the top will not have sharp corners. In this way, when it is inserted, the pressing surface 1011 will come into contact with the installation film, and will not scratch the installation film, and is more secure.

[0045] In this embodiment, the top pressing mechanism 2 further includes a top pressing frame 201, a first driving machine 202, and a first pressing plate 203. The first driving machine 202 is connected to the top pressing frame 201, and drives the first pressing plate 203 to move reciprocally toward the flange boss 101 at the top of the flange boss 101. The first pressing plate 203 is provided with a first clearance hole 2031 that is adapted to the flange boss 101.

[0046] In this way, after the face paper 4 is blown down by the airflow of the air outlet channel 103, the first driving machine 202 on the top pressing frame 201 drives the first pressing plate 203 to press down. Since the first pressing plate 203 is provided with the first clearance hole 2031, the first pressing plate 203 is shaped like a ring that opens around the paperboard 3. This shape of the pressing plate can press down each bent face paper 4 at the same time, further pressing and fitting it tightly, so that it fits more tightly. The first driving machine 202 can use an electric push rod or a gas cylinder hydraulic cylinder, and other driving machines in this application can also be selected.

[0047] In this embodiment, the top pressing mechanism 2 further includes a second driving machine 204 and a second pressing plate 205. The second driving machine 204 is connected to the top pressing frame 201, and drives the second pressing plate 205 to move reciprocally toward the processing table 1 at the top of the flange boss 101. The above setting is not limited, and the second driving machine 204 and the second pressing plate 205 can also be replaced by a clamp plate to clamp and stabilize the paperboard 3 from the top or both sides, or can be replaced by a suction cup to stabilize the paperboard 3.

[0048] In this way, before the paperboard 3 and the paper 4 are folded and attached, the second driving machine 204 will control the second pressing plate 205 to press down, so as to press the paperboard 3 tightly on the processing table 1, thereby stabilizing the paperboard 3 and preventing the paperboard 3 from shaking during the folding and attaching process.

[0049] Preferably, the second pressing plate 205 is provided with a second accommodating hole 2051 matched with the first pressing plate 203, and the first pressing plate 203 is located in the second accommodating hole 2051.

[0050] In this way, the second pressing plate 205 will press the paperboard 3 around the opening, and the stability effect is more accurate.

[0051] Preferably, the bottom of the second pressing plate 205 is provided with an exhaust groove 2052 communicated with the outer wall and the second accommodating hole 2051.

[0052] In this way, after the second pressing plate 205 presses the paperboard 3, the air outlet channel 103 on the folding protrusion 101 will blow air to the folding paper 4 in the second accommodating hole 2051, and the air flow will be sent out through the exhaust groove 2052 at the bottom of the second pressing plate 205, so as not to be blocked in the second accommodating hole 2051 and not to be reflected to the paper 4.

[0053] Preferably, the folding protrusion 101 is a polygonal protrusion.

[0054] In this way, the polygonal protrusion is matched with the polygonal opening, and the paper 4 is cut to be matched with the shape of the opening, such as X-shaped for a quadrilateral or Y-shaped for a triangle, and so on. Each area of the divided paper 4 will form a triangle, and the bottom side of the triangle is parallel to the polygonal protrusion, so that the folding effect is better and the attachment to the base paper is more compact.

[0055] Preferably, the air outlet channel 103 on each side of the folding protrusion 101 is provided with a plurality of air outlet channels 103, and the above setting is not limited. The air outlet channel 103 can be arranged on each side or on some sides.

[0056] In this way, the paper 4 can be subjected to force from multiple positions at the same time, and the folding and attaching of the paper 4 is more uniform and compact.

[0057] The above setting is not limited. When the folding protrusion 101 and the processing table 1 are moved by a mechanical hand or manually, the folding protrusion 101 and the processing table 1 can be used in an integrated structure, and when the folding protrusion 101 is used to rise from the bottom of the opening, the folding protrusion 101 and the processing table 1 are used in a split structure, and the folding protrusion 101 is driven to rise and fall by a conventional mechanism such as a cylinder.

[0058] Although the present application has been described in detail with reference to the foregoing embodiments, the scope of the present application is not limited thereto, and any person skilled in the art, according to the technical range disclosed in the present application and the inventive concept thereof, can make equivalent substitutions or changes within the technical range disclosed in the present application, and such should be encompassed within the scope of the present application.
