Description

Technical Field

[0001] This utility model relates to the technical field of paper trimming machines, specifically to a composite paperboard trimming machine with anti-rollover function. Background Technology

[0002] Composite paperboard is widely used in various fields, including construction, packaging, and furniture manufacturing. It can also be used for the preservation packaging of fruits and vegetables. Composite paperboard is a board material made from two or more materials through a composite processing technology. This type of board is typically composed of paper, paperboard, and other materials laminated together to improve the appearance and strength of the paper and paperboard, while enhancing their waterproof, moisture-proof, oil-resistant, and airtight aroma-preserving properties. This material is resource-saving, environmentally friendly, low-cost, lightweight, high-strength, non-deformable, rigid, and has strong cushioning properties. It also provides good sound and heat insulation and is recyclable, meeting the environmental protection requirements of resource recycling. During the lamination process, an edge trimming machine is used to cut the edges of the base paper to align with the edges of the paperboard, improving the quality of the composite paperboard production.

[0003] During storage, the edges of the raw paper may become damp or squeezed, causing them to curl. During the cutting process, the curled edges affect the accuracy of the cutting. When the raw paper enters the trimming machine, the curled edges tend to stack with the raw paper, thus affecting the cutting effect. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a composite paperboard base paper trimming machine with anti-roll-up function, which solves the technical problems of the base paper's edge rolling affecting its edge cutting accuracy and the rolled edge stacking with the base paper affecting the cutting effect of the cutting blade on the base paper's edge.

[0005] According to one aspect, at least one embodiment of the present invention provides a composite paperboard trimming machine with anti-roll-up function, including an assembly frame, wherein slide rods are symmetrically fixedly connected inside the assembly frame, and an assembly shell is symmetrically slidably connected to the outer end of the slide rods, and an edge pressing component is provided at the outer end of the assembly shell;

[0006] The pressing assembly includes an upper pressing roller and a lower pressing roller that are symmetrically rotatably connected to the outer end of the assembly shell, and a cutting blade is fixedly connected to one side of the assembly shell.

[0007] The assembly shell is F-shaped, and the pressing assembly further includes an upper pulley and a lower pulley that are symmetrically rotatably connected inside the assembly shell. The upper pulley is fixedly connected to the upper pressure roller, and the lower pulley is fixedly connected to the lower pressure roller.

[0008] For example, the pressing assembly also includes an upper connecting belt sleeved between the two upper pulleys and a lower connecting belt sleeved between the two lower pulleys.

[0009] For example, the upper pulley and the lower pulley have the same radius, and the pressing assembly also includes a drive gear and a driven gear disposed inside the assembly housing. The drive gear and the driven gear mesh with each other and have the same radius. The driven gear is fixedly connected to one of the lower pulleys, and the drive gear is rotatably connected inside the assembly housing.

[0010] For example, the pressing assembly also includes a connecting pulley fixedly connected to the top of the transmission gear, a transmission belt is sleeved between the connecting pulley and one of the upper pulleys, and a first servo motor is fixedly connected to the outer end of the assembly housing, and the output end of the first servo motor is fixedly connected to the connecting pulley.

[0011] For example, the outer end of the assembly frame is symmetrically fixedly connected with an upper clamping plate, and an installation roller is rotatably connected between the two upper clamping plates. The outer end of the installation roller is clamped with a paper roll, and the paperboard of the paper roll is placed between the upper pressure roller and the lower pressure roller.

[0012] For example, a bidirectional lead screw is threaded between the two assembly shells, and a throttle is fixedly connected to one end of the bidirectional lead screw, which is rotatably connected to the outer end of the assembly frame.

[0013] For example, a base frame is fixedly connected to the bottom end of the assembly frame, and lower clamping plates are symmetrically fixedly connected to the bottom and top of the base frame, with a take-up roller rotatably connected between the two lower clamping plates.

[0014] For example, a second servo motor is fixedly connected to the outer end of one of the lower plates, and the output end of the second servo motor is fixedly connected to the take-up roller.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] In this invention, the upper and lower pressure rollers press down on both sides of the paper to make the edges of the paper flat, preventing the edges of the paper from curling up during the cutting process and affecting the cutting accuracy. At the same time, after the paper is cut, the upper and lower pressure rollers press and smooth it again from the cut edges to prevent the edges of the paper from curling up when it is recycled. Furthermore, the paper is smoothed before cutting to prevent the edges of the paper from curling up and affecting the cutting effect of the cutting blade. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0025] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0026] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] like Figures 1-4 As shown, it illustrates a composite paperboard trimming machine with anti-roll-up function in one embodiment of the present invention, including an assembly frame 1, with slide rods 2 symmetrically fixedly connected inside the assembly frame 1, and an assembly shell 3 symmetrically slidably connected to the outer end of the slide rods 2, and an edge pressing component 4 provided at the outer end of the assembly shell 3.

[0031] The pressing assembly 4 includes an upper pressing roller 401 and a lower pressing roller 402 that are symmetrically rotatably connected to the outer end of the assembly shell 3, and a cutting blade 403 is fixedly connected to one side of the assembly shell 3.

[0032] The assembly shell 3 is F-shaped, and the pressing assembly 4 also includes an upper pulley 404 and a lower pulley 406 that are symmetrically rotatably connected inside the assembly shell 3. The upper pulley 404 is fixedly connected to the upper pressure roller 401, and the lower pulley 406 is fixedly connected to the lower pressure roller 402.

[0033] In some examples, the paper roll 7 is first placed on the outer end of the mounting roller 6 between the two sets of upper clamping plates 5. One end of the paper roll 7 is pulled to pass it between the upper pressure roller 401 and the lower pressure roller 402. At this time, the upper pressure roller 401 and the lower pressure roller 402 squeeze the edge of the paper roll 7, so that the edge of the rolled paper roll 7 is smoothed. When the paper roll 7 passes between the upper pressure roller 401 and the lower pressure roller 402, the cutting blade 403 at the outer end of the assembly shell 3 cuts the edge of the paper roll 7 and presses the edge of the paper roll 7 to prevent the edge of the rolled paper roll 7 from affecting its cutting accuracy. At the same time, the upper pressure roller 401 and the lower pressure roller 402 are used to smooth the rolled edge of the paper roll 7 to prevent the rolled paper roll 7 from stacking and affecting the cutting effect of the cutting blade 403 on the edge of the paper roll 7.

[0034] For example, such as Figures 1-4 As shown, the pressing assembly 4 also includes an upper connecting belt 405 sleeved between two upper pulleys 404, and a lower connecting belt 407 sleeved between two lower pulleys 406.

[0035] The upper pulley 404 and the lower pulley 406 have the same radius. The pressing assembly 4 also includes a transmission gear 408 and a driven gear 409 disposed inside the assembly housing 3. The transmission gear 408 and the driven gear 409 mesh with each other and have the same radius. The driven gear 409 is fixedly connected to one of the lower pulleys 406. The transmission gear 408 is rotatably connected inside the assembly housing 3.

[0036] The pressing assembly 4 also includes a connecting pulley 4010 fixedly connected to the top of the transmission gear 408. A transmission belt 4011 is sleeved between the connecting pulley 4010 and one of the upper pulleys 404. A first servo motor 4012 is fixedly connected to the outer end of the assembly shell 3. The output end of the first servo motor 4012 is fixedly connected to the connecting pulley 4010.

[0037] In some examples, during the cutting of paper roll 7, the first servo motor 4012 rotates counterclockwise. At this time, the first servo motor 4012 drives the connecting pulley 4010 fixed at its output end to drive the transmission gear 408 to rotate. Since the transmission gear 408 meshes with the driven gear 409, the rotating transmission gear 408 drives the driven gear 409 to rotate. During the rotation of the transmission gear 408, the connecting pulley 4010 at its top drives the upper pulley 404 sleeved on the transmission belt 4011 to rotate inside the assembly shell 3. The lower pulley 406 fixed on the driven gear 409 drives the other lower connecting belt 407 sleeved on the lower connecting belt 407 to rotate. One lower pulley 406 rotates, while the upper connecting belt 405 drives two upper pulleys 404 to rotate simultaneously. This causes the upper pulleys 404 and lower pulleys 406 to drive the upper pressure rollers 401 and 402 to rotate in opposite directions, thereby moving the paper roll 7 towards the unloading position of the assembly frame 1. This allows the two edges of the paper roll 7 to pass through the cutting blade 403, thus cutting the two sides of the paper roll 7. The transmission gear 408 and driven gear 409 of the same radius, as well as the upper pulleys 404 and 406 of the same radius, cause the upper pressure rollers 401 and 402 to rotate at the same speed, making the paper roll 7 more stable during transport.

[0038] like Figure 2 and Figure 5 As shown, it illustrates a composite paperboard trimming machine with anti-roll-up function in another embodiment of the present invention. The outer end of the assembly frame 1 is symmetrically fixedly connected with upper clamping plates 5. An installation roller 6 is rotatably connected between the two upper clamping plates 5. The outer end of the installation roller 6 is clamped with a paper roll 7. The paperboard of the paper roll 7 is disposed between the upper pressure roller 401 and the lower pressure roller 402.

[0039] In some examples, the mounting rollers 6 between the two sets of upper clamping plates 5 facilitate the installation and removal of paper rolls 7, thereby facilitating feeding and unloading.

[0040] For example, such as Figure 1 As shown, a double-acting screw 8 is threaded between the two assembly shells 3. One end of the double-acting screw 8 is fixedly connected to a handle 9, which is rotatably connected to the outer end of the assembly frame 1.

[0041] In some examples, when trimming the edge of the paper roll 7, the distance between the two sets of cutting blades 403 needs to be adjusted according to the width of the cardboard. At this time, the handle 9 is turned, and the handle 9 drives the bidirectional lead screw 8 to rotate between the two sets of assembly shells 3. Since the outer end of the bidirectional lead screw 8 is provided with two sets of threads and is set in opposite directions, the two sets of assembly shells 3 move towards each other or in opposite directions at the same time, thereby moving the distance between the cutting blades 403 fixed at the outer ends of the two assembly shells 3, so as to facilitate the adjustment of the cutting width at the edge of the paper roll 7 according to the cutting requirements.

[0042] For example, such as Figure 5As shown, a base frame 10 is fixedly connected to the bottom end of the assembly frame 1, and a lower clamping plate 11 is symmetrically fixedly connected to the bottom side and top end of the base frame 10. A winding roller 12 is rotatably connected between the two lower clamping plates 11.

[0043] One of the lower clamping plates 11 has a second servo motor 13 fixedly connected to its outer end, and the output end of the second servo motor 13 is fixedly connected to the take-up roller 12.

[0044] In some examples, waste paper strips are generated after the edges of the paper roll 7 are cut. The waste paper strips are wrapped around the outer end of the take-up roller 12. At this time, the second servo motor 13 drives the take-up roller 12 to rotate, thereby winding up the waste paper strips, which facilitates the recycling of waste materials. The recycled waste materials can be reused. At the same time, the waste paper strips are wound up and recycled to prevent the waste paper strips from getting tangled with the paper roll 7 and affecting the cutting effect of the paper roll 7.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
