Technical Field
[0001] This utility model relates to the field of slitting device technology, and more specifically, to a slitting device for producing self-adhesive labels. Background Technology
[0002] Self-adhesive labels, widely used in product identification and packaging, consist of a face stock, adhesive, and substrate, offering ease of use and high adaptability. There are many common types of self-adhesive labels, such as film labels, which are flexible, and multi-layered labels, which offer diverse functions. Among these, foil labels are characterized by their rigidity, excellent electrical and thermal conductivity, and are often used for packaging and labeling high-end products, offering both aesthetic appeal and durability.
[0003] Currently, self-adhesive labels made of metal foil typically require slitting during production. Existing slitting machines generate heat as the large sheets of labels pass through the circular cutter. If this heat accumulates on the cutter and the labels, it can potentially melt the adhesive, thus affecting label quality. Therefore, we propose a slitting device for self-adhesive label production. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a slitting device for the production of self-adhesive labels, so as to solve the technical problem that the heat generated by the existing slitting machine when slitting metal foil self-adhesive labels is easily accumulated on the blade and the label, causing the adhesive to melt and affecting the label quality to a certain extent.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a slitting device for producing self-adhesive labels, including a base, a frame arranged on the upper surface of the base, a tensioning mechanism arranged on the inner wall of the frame, a feeding mechanism arranged at one end of the frame, a receiving mechanism arranged at the other end of the frame, a slitting mechanism arranged in the middle of the frame, and a heat dissipation mechanism arranged inside the base.
[0006] The slitting mechanism includes a rotating rod rotatably installed in the middle of the frame. A cutter is fixed on the rotating rod. Cavities A and B are respectively opened in the rotating rod and the cutter. Cavities A and B are connected. A bracket is fixed in cavity A. A baffle is provided on the bracket and the baffle is placed in cavity B.
[0007] Preferably, the tensioning mechanism includes slide rail A and slide rail B on the frame. A pulley A slides in slide rail A, and a folding roller A is arranged in pulley A. One end of folding roller A is connected to a cylinder A, and the cylinder A is fixed to the top of the outer side of the frame. A pulley B slides in slide rail B, and a folding roller B is arranged in pulley B. One end of folding roller B is connected to a cylinder B, and the cylinder B is fixed to the bottom of the outer side of the frame.
[0008] Preferably, a guide roller A is arranged on one side of the folding roller A, and a guide roller B is arranged on one side of the folding roller B.
[0009] Preferably, the feeding mechanism includes a turntable A arranged on the frame, and a coil rod A is arranged in the middle of the surface of the turntable A.
[0010] Preferably, the receiving mechanism includes a turntable B arranged on a frame, with a winding rod B arranged at both ends of the surface of the turntable B. One end of the winding rod B has a hexagonal socket, into which a hexagonal insert is inserted. The hexagonal insert is fixed to a drive motor A. The drive motor A is movably mounted on a column via an electric slide, and the column is fixed to a base.
[0011] Preferably, the heat dissipation mechanism includes a circulation pump, the input end of which is connected to the output end of the radiator via pipe A, the input end of the radiator is connected to a rotary joint A via pipe B, and the rotary joint A is fixed to one end of the rotating rod, the output end of which is connected to the rotary joint B via pipe C, and the rotary joint B is fixed to the other end of the rotating rod.
[0012] Preferably, the slitting mechanism further includes a housing fixed to the frame and a drive motor B. The drive motor B is fixed inside the housing, and a bevel gear A is fixed to the output end of the drive motor B. The bevel gear B meshes with the surface of the bevel gear A, and the bevel gear B is fixed to one end surface of the rotating rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The hollow structure design of the rotating rod and cutter in this utility model allows the cooling liquid transmitted by the circulating pump to be delivered inside. This way, the heat generated by the cutter when cutting large sheets of self-adhesive labels made of metal foil can be absorbed and carried away, preventing the heat from melting the adhesive on the large sheets of labels and causing deformation of the metal foil. Furthermore, a baffle is installed inside cavity B, which can disperse the cooling liquid entering cavity A to the side of the cutter. This external position is the part that directly contacts the large sheets of labels and is most prone to generating heat, and the cooling liquid flowing from this position can efficiently carry away the heat.
[0015] 2. This utility model, through the design of pulley A and slide rail A, allows folding roller A to move smoothly laterally at the top of the frame, while through the design of pulley B and slide rail B, allows folding roller B to move smoothly laterally at the bottom of the frame. The movement of folding rollers A and B allows the large labels passing over their surfaces to be tensioned. The tensioned labels are more likely to adhere tightly to the cutter, facilitating the cutter's rotation for slitting. This utility model, through the design of guide roller A and guide roller B, allows the large labels rolled on the winding rod A to be guided by guide roller A to folding rollers A and B, and then the slit labels are guided by guide roller B to the winding rod B, achieving the effect of guiding and conveying.
[0016] 3. This utility model has two rollers B. After one roller B is fully wound with the cut label sheets, it can be immediately rotated and repositioned via turntable B. The other roller B can then be used to continue winding the cut label sheets, saving loading and unloading time. By designing a hexagonal socket and hexagonal rod structure, when the hexagonal rod is inserted into the hexagonal socket, the power output from the drive motor A can be transmitted to the roller B. When the hexagonal rod is disengaged from the hexagonal socket, the power transmission is disconnected. This allows the two rollers B to be rotated for repositioning and unloading. The installation of the electric slide allows the drive motor A to move, thus controlling the insertion and disengagement of the hexagonal rod and the hexagonal socket. Attached Figure Description

[0028] like Figures 1 to 9 As shown, the present invention relates to a slitting device for producing self-adhesive labels, comprising a base 1, a frame 2 arranged on the upper surface of the base 1, a tensioning mechanism 3 arranged on the inner wall of the frame 2, a feeding mechanism 4 arranged at one end of the frame 2, a receiving mechanism 5 arranged at the other end of the frame 2, a slitting mechanism 6 arranged in the middle of the frame 2, and a heat dissipation mechanism 7 arranged inside the base 1.
[0029] The slitting mechanism 6 includes a rotating rod 601 rotatably mounted in the middle of the frame 2. A cutter 602 is fixed on the rotating rod 601. Cavities A603 and B604 are respectively opened in the rotating rod 601 and the cutter 602. Cavities A603 and B604 are connected. A bracket 605 is fixed in cavity A603. A baffle 606 is provided on the bracket 605 and is placed in cavity B604. The hollow structure design of the rotating rod 601 and the cutter 602 in this invention allows the cooling liquid transmitted by the circulating pump 701 to be delivered inside. This way, the heat generated by the cutter 602 when cutting large sheets of self-adhesive labels 8 made of metal foil can be absorbed and carried away, preventing the heat from melting the adhesive on the large sheet of labels 8 and causing deformation of the metal foil. Furthermore, a baffle 606 is installed in the cavity B604. The baffle 606 can disperse the cooling liquid entering the cavity A603 to the inner side of the cutter 602. This outer part is the part that directly contacts the large sheet of labels 8 and is most likely to generate heat. The cooling liquid flowing from this part can efficiently carry away the heat.
[0030] In an embodiment of this utility model, the tensioning mechanism 3 includes a slide rail A301 and a slide rail B302 opened on the frame 2. A pulley A303 slides in the slide rail A301, and a folding roller A304 is arranged in the pulley A303. One end of the folding roller A304 is connected to a cylinder A305, and the cylinder A305 is fixed to the top of the outer side of the frame 2. A pulley B306 slides in the slide rail B302, and a folding roller B307 is arranged in the pulley B306. One end of the folding roller B307 is connected to a cylinder B308, and the cylinder B308 is fixed to the bottom of the outer side of the frame 2. This invention, through the design of pulley A303 and slide rail A301, enables folding roller A304 to move smoothly laterally at the top of the frame 2. Furthermore, through the design of pulley B306 and slide rail B302, folding roller B307 can move smoothly laterally at the bottom of the frame 2. The movement of folding rollers A304 and B307 allows the large label sheet 8 passing over their surface to be tensioned. The tensioned label sheet 8 is more likely to adhere tightly to the cutter 602, facilitating the rotation of the cutter 602 for slitting and processing.
[0031] In an embodiment of this invention, a guide roller A309 is arranged on one side of the folding roller A304, and a guide roller B3010 is arranged on one side of the folding roller B307. By designing the structures of guide rollers A309 and B3010, this invention allows the large label sheets 8 rolled on the winding rod A402 to be guided by guide roller A309 to the folding rollers A304 and B307, and then guided by guide roller B3010 to the winding rod B502, thus achieving the effect of guided transport.
[0032] In an embodiment of this utility model, the feeding mechanism 4 includes a turntable A401 arranged on the frame 2, and a winding rod A402 is arranged in the middle of the surface of the turntable A401. By designing the structure of the turntable A401 and the winding rod A402, this utility model allows the rolled label sheets 8 to be placed on its surface, which facilitates rotation and feeding.
[0033] In an embodiment of this utility model, the receiving mechanism 5 includes a turntable B501 arranged on the frame 2. A winding rod B502 is arranged at both ends of the surface of the turntable B501. A hexagonal socket 503 is opened at one end of the winding rod B502. A hexagonal insert 504 is inserted into the hexagonal socket 503. The hexagonal insert 504 is fixed to the drive motor A505. The drive motor A505 is movably mounted on the column 507 through the electric slide table 506. The column 507 is fixed on the base 1. This utility model has two winding rods B502. After one winding rod B502 is fully wound with the pre-cut label sheets 8, it can be immediately rotated and repositioned via turntable B501. The other winding rod B502 can then be used to continue winding the pre-cut label sheets 8, thus saving loading and unloading time. Through the design of the hexagonal socket 503 and hexagonal rod 504, when the hexagonal rod 504 is inserted into the hexagonal socket 503, the power output of the drive motor A505 can be transmitted to the winding rod B502. When the hexagonal rod 504 is disengaged from the hexagonal socket 503, the power transmission is disconnected. This allows the two winding rods B502 to be rotated for repositioning and unloading. The installation of the electric slide table 506 allows the drive motor A505 to move, thus controlling the insertion and disengagement of the hexagonal rod 504 and the hexagonal socket 503.
[0034] In an embodiment of this invention, the heat dissipation mechanism 7 includes a circulation pump 701. The input end of the circulation pump 701 is connected to the output end of the radiator 703 via pipe A702. The input end of the radiator 703 is connected to a rotary joint A705 via pipe B704, and the rotary joint A705 is fixed to one end of the rotating rod 601. The output end of the circulation pump 701 is connected to a rotary joint B707 via pipe C706, and the rotary joint B707 is fixed to the other end of the rotating rod 601. This invention, through the design of the circulation pump 701, pipe A702, pipe B704, and pipe C706, allows the cooling liquid to circulate into cavities A603 and B604, achieving the effect of active circulation of the cooling liquid. Furthermore, the installation of rotary joints A705 and B707 ensures that the rotating rod 601 does not rotate with pipes B704 and C706, achieving the effect of separation of rotational force.
[0035] In this embodiment of the invention, the slitting mechanism 6 further includes a housing 607 fixed to the frame 2 and a drive motor B608. The drive motor B608 is fixed inside the housing 607, and a bevel gear A609 is fixed to the output end of the drive motor B608. A bevel gear B6010 meshes with the surface of the bevel gear A609, and the bevel gear B6010 is fixed to one end surface of the rotating rod 601. By designing the structure of the drive motor B608, bevel gear A609, and bevel gear B6010, this invention enables the rotational force output by the drive motor B608 to be transmitted to the rotating rod 601, thus achieving the effect of power output.
[0036] Working Principle: This embodiment provides a slitting device for self-adhesive label production. During use, the operator needs to first connect an external power supply to the device and control its operation via the control panel. The operator places the roll of self-adhesive labels (such as metal foil labels) to be slit onto the roll rod A402. After placement, the label roll 8 is pulled across the guide roller A309, then around the surface of the folding roller A304, then over the surface of the folding roller B307, and finally around the guide roller B3010 and connected to the roll rod B502. At this time, the operator controls the operation of cylinders A305 and B308 within the tensioning mechanism 3. Cylinder A305... Pulling folding roller A304 and sliding it within slide rail A301 via pulley A303, while cylinder B308 pulls folding roller B307 and slides it within slide rail B302 via pulley B306. This causes folding rollers A304 and B307 to move away from each other, tensioning the large label sheet 8 passing between them. The tensioned label sheet 8 will then adhere to the cutter 602. At this point, the operator starts drive motors A505 and B608. Drive motor A505 rotates the hexagonal insert 504 connected to its output end, causing the winding rod B502 to rotate as well. This pulls and rewinds the large label sheet 8 wound on the winding rod A402. The motor B608 rotates the bevel gear A609 fixed at its output end. Bevel gear A609 then meshes with and rotates bevel gear B6010, which in turn rotates the internally fixed rotating rod 601. As the rotating rod 601 rotates, the cutter 602 fixed on its surface rotates accordingly, cutting the label sheet 8. The cut label sheet 8 is then wound up by the rotating winding rod B502. Once one winding rod B502 is full of label sheet 8, the worker can manually cut the label sheet 8. Then, by changing the position of the two winding rods B502 via the turntable B501, the winding process can continue until the label sheet 8 is fully wound up. The roll of labels 8 is removed from the surface of the roller B502 by the worker. During the slitting process, the worker also needs to start the circulation pump 701. The circulation pump 701 circulates the cooling liquid in pipes B704, A702 and C706. After circulating into cavities A603 and B604, the cooling liquid is affected by the baffle 606 and passes through the inside side of the cutter 602, absorbing the heat generated by the cutter 602 in slitting the labels 8. The cooling liquid after absorbing the heat is transferred to the radiator 703 for heat dissipation and removal, and finally circulates back into cavities A603 and B604 for use.
