Description

Technical Field

[0001] This utility model relates to the field of paper hot stamping production technology, and in particular to a cutting device for hot stamping paper. Background Technology

[0002] In the process of hot stamping production of paper products, hot stamping paper is usually designed in multiple rolls of different widths according to the positions on the paper to be hot stamped, thereby improving the utilization rate of the hot stamping paper. However, the hot stamping paper rolls that are currently purchased from outside are usually quite wide. During the packaging and printing process, they need to be cut into the width required for actual use. With existing cutting devices, it is inconvenient to load and fix the hot stamping paper rolls on the frame. Moreover, each time the hot stamping paper roll is cut, the length of the hot stamping paper roll needs to be measured with a tape measure, then fixed on the rotating frame, and cut with a cutter. Cutting hot stamping paper is time-consuming, labor-intensive, and results in inaccurate cutting widths. Summary of the Invention

[0003] The purpose of this utility model is to provide a cutting device for hot stamping foil, so as to solve the problem of cutting hot stamping foil rolls of different lengths and widths into hot stamping foil rolls of the required width, and to provide a convenient and accurate cutting device for hot stamping foil rolls.

[0004] To achieve the above objectives, this utility model is implemented as follows: A hot stamping foil slitting device includes a frame and a hot stamping foil holder. A pair of opposing side plates extend from the upper ends of both ends of the frame. Each side plate has a rotating shaft cylinder, and the two rotating shaft cylinders are concentrically arranged. One of the rotating shaft cylinders has a connector, which includes a sleeve shaft and a rod rotatably connected inside the sleeve shaft. One end of the rod extending outside the sleeve shaft has a tapered head. The other rotating shaft cylinder has a rotatable rotating shaft. The rotating shaft has a dividing post on its shaft body. One side of the dividing post is connected to a power device. The front end of the rotating shaft has a pair of locking posts. The hot stamping foil holder is connected between the tapered head of the connector and the rotating shaft. The hot stamping foil holder includes a tubular shaft and a sleeve. One end of the tubular shaft has a positioning plate for positioning one side of the hot stamping foil roll. The sleeve… The device includes a pressure plate with a sleeve at its center. The inner wall of the sleeve is circumferentially arrayed with multiple layers of elastic retaining beads. A tube shaft is fitted inside the sleeve and engaged with the tube shaft by the elastic retaining beads to fix the other end of the hot stamping foil roll on the tube shaft. At the end of the tube shaft furthest from the positioning plate, a pair of slots corresponding to the retaining posts are provided. The slots engage with the retaining posts to connect the rotating shaft to the hot stamping foil holder. A connector is movably fitted onto the rotating shaft sleeve. The conical head presses or releases the hot stamping foil holder by the expansion and contraction of the connector on the rotating shaft sleeve. A side plate has a sliding rod with a movable cutting device. The cutting device includes a cutting rod with a cutting blade facing the hot stamping foil roll. Rotating and pressing down the cutting rod cuts the rotating hot stamping foil roll into a suitable width by the cutting blade.

[0005] Furthermore, the power unit includes a motor, a small pulley connected to the motor's output shaft, and a large pulley coaxially connected to the rotating shaft. The large pulley and the small pulley are connected via belt drive. The rotation of the rotating shaft, driven by the motor of the power unit, rotates the hot stamping foil holder, thereby rotating the hot stamping foil roll.

[0006] Furthermore, the large pulley is provided with a connecting end, and the connecting end has a screw hole. One side of the partition post is sleeved on the connecting end, and the rotating shaft is fixed by a fixing screw through the screw hole.

[0007] Furthermore, a first bearing is fitted on the other side of the partition column, and the first bearing is installed on the rotating shaft cylinder, so that the rotating shaft and the frame are rotatably connected.

[0008] Furthermore, the locking post is provided with locking holes, and the tube shaft is connected and fixed after being inserted into the locking holes by an elastic clamp.

[0009] Furthermore, a groove is provided axially at one end of the sleeve shaft, and a second bearing is installed inside the groove. The second bearing is connected to the sleeve rod, so that a rotatable connection is formed between the sleeve shaft and the sleeve rod.

[0010] Furthermore, the frame also includes a positioning ring for fixing the length of the cutter. The positioning ring has multiple circumferentially arranged sliding plates, which are movably fitted onto the pressure plate. One of the sliding plates is also equipped with a scale. The scale allows for sliding extension to a pre-selected position at the front end of the pressure plate, ensuring the sliding width of the hot stamping paper roll. During cutting, the cutter only needs to adhere to the surface of the positioning ring to achieve a fixed-length cut.

[0011] Furthermore, the other end of the sleeve shaft is provided with a swing hole perpendicular to the axial direction. A tensioning handle is installed on the swing hole. One end of the tensioning handle is rotatably connected to a support rod extending from the side plate. A rotating part is provided in the middle of the tensioning handle near the support rod. The rotating part is rotatably connected to the swing hole via a swing shaft. The side plate is provided with a first spring connecting end. A second spring connecting end is provided on the tensioning handle away from the support rod. A spring is connected between the first spring connecting end and the second spring connecting end. By means of the tension of the spring, the tensioning handle swings the connector toward the hot stamping foil holder, so that the connector presses the hot stamping foil holder.

[0012] Furthermore, one end of the cutter rod is provided with a sleeve hole for it to rotate on the slide rod. A pressure plate is provided on the cutter rod, and the cutter is connected between the pressure plate and the cutter rod via a rotating shaft. A clamping screw is provided on the pressure plate, and the clamping screw is threadedly connected to the cutter rod, clamping and fixing the cutter. During installation, the cutter is rotatably connected between the pressure plate and the cutter rod via the rotating shaft. The cutting angle of the cutter blade on the hot stamping paper roll can be adjusted precisely via the rotating shaft, and finally, it is fixed by the clamping screw.

[0013] Furthermore, the cutter bar has a fixing rod on the same side as its cutter and a fixing groove on the opposite side of its cutter. A support rod is provided between the side plates for engaging and fixing the fixing groove. The fixing rod allows the cutter bar to be supported on the frame when the slitting device is not in use, thus ensuring the sharp part of the cutter faces inwards, better preventing injury to personnel. The support rod provides support when the cutter bar is rotated to the rear end of the slitting device, and stable support is achieved through the cooperation of the fixing groove and the support rod.

[0014] In this invention, when cutting hot foil rolls, the hot foil rolls are first placed on the tube shaft of the hot foil holder. One end of the hot foil roll is positioned by the positioning on the tube shaft, and then the holder is placed on the other end of the tube shaft. The hot foil roll is fixed at the other end by the pressure plate of the holder. Since the pressure plate is provided with a sleeve with elastic retaining beads, the pressure plate can be well connected to the tube shaft through the elastic retaining beads. The pressure plate is convenient to remove and convenient to fix the hot foil roll. After the hot foil roll is fixed on the hot foil holder, first connect the slot of one end of the tube shaft to the pin of the rotating shaft, and then fix the tube shaft by inserting the elastic clamp into the hole. Then, by loosening the tension handle, the sleeve of the connector head moves towards the side plate, aligning the conical head of the sleeve with the tube opening of the tube shaft. After loosening the tension handle, the connector head swings under the action of the spring and presses against the tube opening of the tube shaft, thus realizing the rotational connection of the two ends of the hot foil roll on the holder. After the hot foil roll is connected, according to the requirements of cutting the hot foil roll, the movable positioning ring can be used to extend the hot foil roll to the required length. Then, the blade of the cutting device is attached to the surface of the positioning ring, the power device is started, and the hot foil roll rotates and presses down the cutting rod. The rotating hot foil roll is cut into the appropriate width by the cutting blade.

[0015] This invention utilizes the rotational connection of the sleeve rod on the sleeve shaft to ensure that the connector can still rotate well after being pressed and connected to the hot stamping foil roll holder.

[0016] This invention utilizes a retractable positioning ring with a scale to effectively position and control the width of the hot stamping paper rolls, making it convenient and quick.

[0017] This invention utilizes the elastic retaining beads of the pressure plate to effectively fix the hot stamping foil roll, and facilitates its movement, removal, and placement.

[0018] This invention utilizes the tensioning effect of a spring to connect the connector to the hot stamping foil roll holder, thus making the loading and unloading of the hot stamping foil roll holder convenient and quick. Attached Figure Description

Detailed Implementation

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] Reference Figure 1 A hot stamping foil cutting device includes a frame 1 and a hot stamping foil holder 5. A pair of opposing side plates 11 extend from the upper ends of both ends of the frame 1. Each side plate 11 is provided with a rotating cylinder 12. The pair of rotating cylinders 12 are concentrically arranged. One rotating cylinder 12 is provided with a connector 2, and the other rotating cylinder 12 is provided with a rotatable rotating shaft 3. (Refer to...) Figure 5 , Figure 6A partition column 31 is provided on the shaft of the rotating shaft 3. One side of the partition column 31 is connected to the power device 9 for transmission. The other side of the partition column 31 is fitted with a first bearing 18. The first bearing 18 is installed on the rotating shaft cylinder 12, so that the rotating shaft 3 and the frame 1 form a rotating connection. The hot stamping paper holder 5 is connected between the connector 2 and the rotating shaft 3.

[0032] The power unit 9 includes a motor 91, a small pulley 92 connected to the power output shaft of the motor 91, and a large pulley 93 coaxially connected to the rotating shaft 3. More specifically, the large pulley 93 has a connecting end 931 with a screw hole 932. A partition post 31 is sleeved on the connecting end 931 and fixed to the rotating shaft 3 by a fixing screw 933 through the screw hole 932. The large pulley 93 and the small pulley 92 are connected by a belt 94. The rotating shaft 3 rotates through the motor 91 of the power unit 9 to rotate the hot stamping paper holder 5, thereby rotating the hot stamping paper roll 4. The transmission connection between the large pulley 93 and the small pulley 92 can better control the rotation speed of the hot stamping paper holder 5 and ensure the safety of the slitting process.

[0033] Reference Figure 2 , Figure 3 , Figure 4 The connector 2 includes a sleeve shaft 21 and a sleeve rod 22 rotatably connected inside the sleeve shaft 21. One end of the sleeve rod 22 extending outside the sleeve shaft 21 has a tapered head 221. One end of the sleeve shaft 21 has an axially upwardly formed groove 212. A second bearing 23 is installed inside the groove 212 and is connected to the sleeve rod 22, forming a rotatable connection between the sleeve shaft 21 and the sleeve rod 22. The connector 2 is telescopically connected within the rotating shaft cylinder 12. (Refer to...) Figure 1 The other end of the sleeve 21 is provided with a swing hole 211 perpendicular to the axial direction. A tensioning handle 7 is installed on the swing hole 211. One end of the tensioning handle 7 is rotatably connected to the support rod 14 extending from the side plate 11. A rotating part 71 is provided on the middle part of the tensioning handle 7 near the support rod 14. The rotating part 71 is rotatably connected to the swing hole 211 through a swing shaft 73, so that the tensioning handle 7 rotates around the support rod 14 as the rotation center. During the rotation, the sleeve 21 connected to the rotating part 71 therefore... The arc-shaped oscillation and extension state formed inside the rotating cylinder 12 realizes the relative movement of the conical head 221 of the sleeve 22 towards or away from the hot stamping paper holder 5. When the conical head 221 approaches the hot stamping paper holder 5, the conical head 221 presses the hot stamping paper holder 5 tightly. When the conical head 221 moves away from the hot stamping paper holder 5, the conical head 221 releases the hot stamping paper holder 5. A gap of 10~20mm is provided between the rotating cylinder 12 and the connector 2, so that the connector 2 can realize the arc-shaped oscillation process in the rotating cylinder 12.

[0034] In this embodiment, to ensure that the tensioning handle 7 can press the connector 2, a first spring connecting end 13 is provided on the side plate 11, and a second spring connecting end 72 is provided on the tensioning handle 7 in the direction away from the support rod 14. A spring 8 is connected between the first spring connecting end 13 and the second spring connecting end 72. By means of the tensioning action of the spring 8, the tensioning handle 7 swings the connector 2 toward the hot stamping foil holder 5, so that the connector 2 presses the hot stamping foil holder 5.

[0035] Reference Figure 7 , Figure 8 The hot stamping foil holder 5 includes a tube shaft 51 and a sleeve 52. One end of the tube shaft 51 is provided with a positioning plate 511 for positioning one side of the hot stamping foil roll 4. A pair of slots 512 are provided at the end of the tube shaft 51 away from the positioning plate 511. The slots 512 are used to connect with the rotating shaft 3. When connected, the slots 512 engage with a pair of pins 32 at the front end of the rotating shaft 3 to connect the rotating shaft 3 with the hot stamping foil holder 5. The pins 32 are provided with holes 33. The tube shaft 51 is connected and fixed after being inserted into the holes 33 by an elastic clamp 17.

[0036] Reference Figure 9 The sleeve 52 includes a pressure plate 521. The center of the pressure plate 521 is provided with a sleeve 525. The inner wall surface of the sleeve 525 is circumferentially arrayed with multiple layers of elastic retaining beads 526. When the sleeve 52 is connected, the tube shaft 51 is sleeved in the sleeve 525 of the pressure plate 521, and is movablely engaged with the tube shaft 51 by the elastic retaining beads 526 to achieve the fixed positioning of the other end of the hot stamping paper roll 4 on the tube shaft 51 by the pressure plate 521.

[0037] In this embodiment, the sleeve 52 also includes a positioning ring 522 for the cutter 62 to be cut to a fixed length. The positioning ring 522 is provided with multiple circumferentially arrayed sliding plates 523, and the sliding plates 523 are movably sleeved on the pressure plate 521. One of the sliding plates 523 is also equipped with a scale 524.
