[0011] The conveyor roller pallet is equipped with a pallet positioning locking mechanism, which is located between the conveyor roller pallet and the lifting pallet. When the conveyor roller pallet moves into position on the lifting pallet, the first channel and the upper second channel are correspondingly matched. The lifting pallet is driven by a lifting drive component, which is mounted on the frame. The roller changing support pallet is also mounted on the frame. The lifting drive component uses a lifting drive cylinder. The shifting balls are mounted on a universal ball bearing seat and are located on the bottom surface of the conveyor roller pallet.

[0012] In addition, the conveyor roller pallet is provided with a mounting position for the magnetic roller. The two ends of the magnetic roller shaft are respectively connected to lifting guide sliders, which are supported and connected to the conveyor roller pallet. The die-cutting station is provided with a front vertical guide rail and a rear vertical guide rail. The front vertical guide rail includes a lifting vertical rail and a fixed vertical rail. The lifting vertical rail and the fixed vertical rail are arranged vertically and vertically respectively. When the lifting vertical rail and the fixed vertical rail are closed, they cooperate with the rear vertical guide rail to form a vertical groove for the lifting guide slider to move and guide.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Referring to the accompanying drawings, an embodiment of this invention provides a die-cutting device, such as a magnetic roller 8 die-cutting structure, which includes a die-cutting station 1, a lifting pallet 4, a roller changing support pallet 3, and a roller moving pallet 5. This structure can form a roller changing cooperation structure to allow for the replacement of rollers (such as the magnetic roller 8) so that the rollers can smoothly cooperate with the die-cutting work at the die-cutting station 1.

[0024] The roller changing support plate 3 is located on the front side of the die-cutting station 1, so as to form a support structure on the front side of the die-cutting station 1 for roller changing operation. The roller changing support plate 3 is provided with a longitudinal reference groove 31 and a transverse reference groove 32. The longitudinal reference groove 31 and the transverse reference groove 32 are connected to form a track line on the roller changing support plate 3, so that the roller moving plate 5 can move on it to switch between longitudinal and transverse directions.

[0025] The lifting pallet 4 is positioned at the die-cutting station 1, and has a first channel for upper and lower die-cutting. The lifting pallet 4 also has a longitudinal connecting groove 41. The lifting pallet 4 has a high position and a low position; that is, it can switch between these states by lifting and lowering, and corresponding structures on the lifting pallet 4 (such as the conveyor roller moving pallet 5 and rollers) will rise and fall together. In the high position, the longitudinal connecting groove 41 of the lifting pallet 4 connects with the longitudinal reference groove 31 on the front side (roller changing support pallet 3), forming a rail connection so that the conveyor roller moving pallet 5 can move and change position between the roller changing support pallet 3 and the lifting pallet 4. In the low position, the lifting pallet 4 is in the die-cutting placement position so that the structures on the lifting pallet 4 (such as the conveyor roller moving pallet 5 and rollers) can be die-cut and positioned.

[0026] The conveyor roller pallet 5 is equipped with displacement balls 50 for rolling and shifting within each concave rail. These displacement balls 50 can roll stably along each concave rail, guided by the rails, allowing the conveyor roller pallet 5 to move smoothly and stably between different positions. This enables the pallet to easily transport heavy rollers to different locations, facilitating roller replacement. The conveyor roller pallet 5 also has a second channel for upper and lower die-cutting. Typically, the first and second channels are designed as openwork holes for easy processing and better pallet support. During upper and lower die-cutting, the first and second channels allow rollers (such as magnetic rollers 8) on the conveyor roller pallet 5 to pass through with the lower die-cutting bottom roller for material die-cutting.

[0027] The roller changing mechanism in this die-cutting device operates as follows: A roller (such as a magnetic roller 8) is placed on the corresponding conveyor roller pallet 5. This pallet 5 carries the roller and moves it along the transverse reference groove 32 of the roller changing support pallet 3, then along the longitudinal reference groove 31. It then moves along the longitudinal docking groove 41 of the lifting pallet 4 (in its elevated position), transporting the roller onto the lifting pallet 4 (entering the die-cutting station 1). The lifting pallet 4 then descends from its elevated position to its lower position, causing the conveyor roller pallet 5 and the roller to descend and settle into position, ready for die-cutting. When another roller (such as a magnetic roller 8) needs to be replaced, the lifting pallet 4 rises to... In the high position, the roller moving pallet 5 moves along the longitudinal docking groove 41 toward the longitudinal reference groove 31. The roller moving pallet 5 carries the roller from the lifting pallet 4 at the die-cutting station 1 to the roller changing support pallet 3. Then the roller moving pallet 5 moves out of the roller changing support pallet 3 along the transverse reference groove 32. The roller to be replaced can be moved into the roller changing support pallet 3 along the transverse reference groove 32 of the roller changing support pallet 3 on the corresponding roller moving pallet 5. Then the roller moving pallet 5 carries the roller along the longitudinal reference groove 31 and the longitudinal docking groove 41 to the lifting pallet 4 in the high position (entering the die-cutting station 1) to complete the roller change. Then the lifting pallet 4 descends to the low position for die cutting.

[0028] This die-cutting device facilitates roller changing. Rollers (such as magnetic roller 8) are placed on the roller moving pallet 5 and moved together. Roller changing support pallet 3 and lifting pallet 4 are configured to participate in roller changing. During the transfer process, the roller moving pallet 5 is supported by the roller changing support pallet 3 and lifting pallet 4. The displacement balls 50 on the roller moving pallet 5 can roll stably along each concave rail. With the help of the displacement balls 50 rolling and guiding in each concave rail (including the relevant concave rails below), the roller moving pallet 5 maintains low damping and high stability during roller transfer, reducing labor intensity and making operation more convenient and easier.

[0029] In this invention, "horizontal" and "vertical" refer to being orthogonal in a plane.

[0030] Based on the above embodiments, the following optimizations or further explanations can be made.

[0031] The die-cutting device also includes a roller changing frame 6. The material support part of the roller changing frame 6 is provided with a transverse docking groove 62. The side of the roller changing support plate 3 has a placement position for the roller changing frame 6 to dock. The roller changing frame 6 can stay in the side position of the roller changing support plate 3. The roller changing frame 6 can pre-place spare rollers and roller moving plate 5. The roller changing frame 6 can also retract the replaced rollers and roller moving plate 5. The transverse docking groove 62 and the transverse reference groove 32 are in a track-connecting state. After the transverse docking groove 62 and the transverse reference groove 32 are track-connected, the displacement ball of the roller moving plate 5 can move laterally in the transverse docking groove 62 and the transverse reference groove 32 so that the roller moving plate 5 can move between the material support part of the roller changing support plate and the roller changing frame 6.

[0032] In addition, the material support section of the roller changing frame 6 is provided with a longitudinal changing plate concave rail 61, which is connected to the transverse docking concave rail 62 so that the roller moving plate 5 can move laterally and longitudinally on the roller changing frame 6 to perform corresponding transverse and longitudinal displacement. The longitudinal changing plate concave rail 61 can provide multiple (usually two or more) roller moving plates 5 to move and change plates, and switch the positions between the roller moving plates 5. Different roller moving plates 5 can move longitudinally on the roller changing frame 6 to switch positions, thereby switching different roller moving plates 5 to the transverse docking concave rail 62. The longitudinally switched roller moving plates 5 (with displacement balls) move laterally in and out along the transverse docking concave rail 62.

[0033] The roller changing frame 6 can even be configured as a movable type, for example, equipped with casters (such as directional wheels, swivel wheels, etc., selected according to requirements), forming a roller changing cart mode. The entire roller changing frame 6 can be moved to a position on the side of the die-cutting device to facilitate roller changing, and then it can be moved away, so the side position of the die-cutting device is not occupied, facilitating production operations. The die-cutting device can be installed on the main unit (such as a printing production line).

[0034] When the roller changing frame 6 is movable, the die-cutting device is equipped with a storage roller frame 7, which has several storage roller areas 70 for placing various rollers (such as various magnetic rollers 8). Each storage roller area 70 can hold a corresponding conveyor roller pallet 5 and rollers (such as magnetic rollers 8) as needed. Each storage roller area 70 is provided with a material storage groove 72. The transverse docking groove 62 of the roller changing frame 6 and the material storage groove 72 are in a track-fitting engagement state. So that when the roller changing frame 6 moves to the corresponding storage roller area 70 of the storage roller frame 7, the transverse docking groove 62 on the roller changing frame 6 can be aligned with the material storage groove 72 of the corresponding storage roller area 70, and the conveyor roller pallet 5 can carry the roller along the transverse docking groove 62 and the material storage groove 72. The conveyor roller pallet 5 can smoothly move and change positions between the roller changing frame 6 and the storage roller frame 7. The storage and retrieval roller areas 70 are arranged side by side, and the storage and retrieval material concave rails 72 are arranged in parallel relative to each other, resulting in a more compact structure.

[0035] The longitudinal reference concave rail 31 and the transverse reference concave rail 32 are intersected and connected, with at least two parallel longitudinal reference concave rails 31 and two parallel transverse reference concave rails 32 respectively; the longitudinal plate changing concave rail 61 and the transverse docking concave rail 62 are intersected and connected, with at least two parallel longitudinal plate changing concave rails 61 and two parallel transverse docking concave rails 62 respectively; and at least two parallel storage and retrieval concave rails 72 are provided in the storage and retrieval roller area 70. The displacement balls 50 on the conveyor roller moving pallet 5 can move stably in each concave rail. The displacement balls 50 are set on the universal ball bearing seat 51, which is a mature technology and easy to obtain. The universal ball bearing seat 51 can be set in the mounting hole of the conveyor roller moving pallet 5, and the displacement balls 50 are located on the bottom surface of the conveyor roller moving pallet 5. Typically, the displacement balls 50 are located at the four corners of the conveyor roller moving pallet 5.

[0036] In addition, to facilitate track alignment and optimize the structural layout, the roller changing frame 6 has a track alignment ramp 64 on its side. The transverse docking concave rail 62 extends onto the track alignment ramp 64. The track alignment ramp 64 prevents the main body of the roller changing frame 6 from directly contacting the roller changing support plate 3, facilitating the connection of the roller changing frame 6 and avoiding parts on the side of the frame 9. Furthermore, a track alignment positioning plug 641 is provided at the end of the track alignment ramp 64, and a track alignment positioning slot 642 is provided on the side of the roller changing support plate 3. Track alignment positioning slots 642 are provided on the inlet and outlet sides of each storage and retrieval roller area 70 of the storage and retrieval roller frame 7. The track alignment positioning plug 641 and the track alignment positioning slot 642 correspond and match. When the roller changing frame 6 moves to the roller changing support plate 3 or the storage and retrieval roller frame 7 for track alignment, the track alignment positioning plug 641 and the track alignment positioning slot 642 can be inserted into each other, making the transverse docking concave rail 62 more stable and accurate during track alignment.

[0037] Among them, one end of the transverse reference groove 32 is the first rail pairing port, one end of the transverse docking groove 62 is the second rail pairing port, and one end of the storage and retrieval groove is the third rail pairing port. The interdependent ports enable the displacement ball 50 to move more smoothly and stably when moving in and out of the connection between the transverse reference groove 32, the transverse docking groove 62, and the storage and retrieval groove, and avoid detaching from the groove.

[0038] The conveyor roller moving pallet 5 is equipped with a pallet moving-in-position locking mechanism 45, which is located between the conveyor roller moving pallet 5 and the lifting pallet 4. When the conveyor roller moving pallet 5 moves to its position on the lifting pallet 4 along the longitudinal reference groove 31 and the longitudinal docking groove 41, the pallet moving-in-position locking mechanism 45 can cooperate to lock it, so that the relative position of the moved-in conveyor roller moving pallet 5 on the lifting pallet 4 remains stable, avoiding relative displacement from affecting the subsequent die-cutting accuracy. The pallet moving-in-position locking mechanism 45 can adopt a pin structure (including pin shaft and pin hole), a bolt and nut structure, or other structures, with many options available.

[0039] When the conveyor roller pallet 5 moves into position on the lifting pallet 4, the first channel and the upper second channel are correspondingly matched to ensure that the rollers on the conveyor roller pallet 5 can smoothly cooperate with the structure below for die cutting. The lifting pallet 4 is driven by a lifting drive component 43, and a lifting transmission bracket 44 can be installed for connection. The lifting drive component 43 drives the lifting pallet 4 to perform lifting and lowering actions, forming corresponding high and low positions. The lifting drive component 43 is installed on the frame 9, and the roller changing support pallet 3 is also installed on the frame 9. For example, the lifting drive component 43 can be a lifting drive cylinder, which is more reasonable in structure. A lifting limit component can also be provided to cooperate with the lifting operation.

[0040] The conveyor roller pallet 5 is provided with a mounting position for the magnetic roller 8, which is placed on the conveyor roller pallet 5 so that the die-cutting device can replace the magnetic roller 8. The roller shaft 80 of the magnetic roller 8 is connected to two lifting guide sliders 81 at both ends. The lifting guide sliders 81 are supported and connected to the conveyor roller pallet 5. The lifting guide sliders 81 can be stably supported and held by the conveyor roller pallet 5, so that the magnetic roller 8 is not easy to shift during the transfer of the conveyor roller pallet 5. The position of the magnetic roller 8 on the conveyor roller pallet 5 is relatively stable during the movement (transfer). In addition, the lifting guide sliders 81 will stably guide the magnetic roller 8 in the vertical groove (see below), improving the stability of the lifting and lowering operation of the magnetic roller 8. The die-cutting station 1 is equipped with a front vertical guide rail and a rear vertical guide rail 93. The front vertical guide rail includes a lifting vertical rail 91 and a fixed vertical rail 92. The lifting vertical rail 91 and the fixed vertical rail 92 are arranged vertically and vertically respectively. When the lifting vertical rail 91 and the fixed vertical rail 92 are closed, they cooperate with the rear vertical guide rail 93 to form a vertical slide groove. The vertical slide groove provides a lifting guide slider 81 for lifting and guiding, so that the lifting guide slider 81 can slide vertically and lift within it. When the lifting vertical rail 91 and the fixed vertical rail 92 are separated, they form the front entrance and exit of the vertical slide groove. The front entrance and exit provides a conveyor roller moving plate 5 to carry the lifting guide slider 81 in and out, so that the conveyor roller moving plate 5 can carry the magnetic roller 8 smoothly forward and backward.

[0041] A rotary support bearing is provided between the roller shaft 80 and the lifting guide slider 81 to ensure smoother rotation of the magnetic roller 8. The conveying roller moving plate 5 has a side-protruding support part 52, which is located below the lifting guide slider 81. The side-protruding support part 52 of the conveying roller moving plate 5 supports the lifting guide slider 81. In addition, an auxiliary support pad 94 is provided between the side-protruding support part 52 and the lifting guide slider 81 for convenient and stable support, and easier to match magnetic rollers 8 and lifting guide sliders 81 of different sizes and heights. Different specifications of auxiliary support pads 94 can be configured for selection and replacement. Usually, the lifting guide slider 81 is a block with grooves on the front and rear sides to form a groove structure that matches the front vertical guide rail and the rear vertical guide rail 93 respectively for stable sliding position. The lower side of the lifting guide slider 81 is flat to facilitate support and connection on the lifting plate 4, and facilitates the setting of the auxiliary support pad 94. The front vertical slide rail 952 is connected to a lifting and shifting power component 95. The lifting and shifting power component 95 (such as a cylinder) drives the lifting vertical rail 91 to move up and down. In the figure, the lifting vertical rail 91 is located above the fixed vertical rail 92. The lifting and shifting power component 95 can be mounted on the outside of the frame 9, and a lifting transmission plate 951 can be mounted on the vertical slide rail 952 for stable movement. The lifting transmission plate 951 is connected to the lifting vertical rail 91 for transmission, driving the lifting vertical rail 91 to move up and down. In addition, the frame 9 is provided with a vertical groove 953 for the lifting vertical rail 91 to move up and down. The sliding movement is stable; the upper end of the fixed vertical rail 92 is not higher than the roller moving plate 5 on the lifting plate 4 in the high position, ensuring that the roller moving plate 5 is not interfered with during the movement of the longitudinal reference concave rail 31 and the longitudinal docking concave rail 41; in addition, a pin hole 96 is provided next to the fixed vertical rail 92 for the lifting vertical rail 91 (if downward) to be inserted when it is closed. In the figure, the lifting vertical rail 91 descends and is inserted into the pin hole 96 to form a pin structure, which makes the structure more stable in the closed state. The lifting vertical rail 91 rises and separates from the fixed vertical rail 92 to form the front entrance and exit of the vertical slide groove.

[0042] In addition, die-cutting station 1 is also equipped with a die-cutting bottom roller. The upper side of the die-cutting bottom roller is the magnetic roller mating position. When the magnetic roller 8 is in the magnetic roller mating position, it can cooperate with the die-cutting bottom roller to participate in the die-cutting work. Above the magnetic roller mating position is a lifting and adjusting plate 97, on which pressure rollers 98 are provided. The pressure rollers 98 can move up and down together with the lifting and adjusting plate 97. The number of pressure rollers 98 can be set according to needs; a pair can be set in front and behind for a compact structure and good and stable pressure application. The lifting and adjusting plate 97 has multiple lifting and adjusting methods. Pressure adjustment is achieved by driving the height of the lifting and adjusting plate 97. The lifting and adjusting technology is relatively mature; for example, a screw and nut seat can be used to rotate and adjust the pressure. A pressure gauge can also be added for easy observation. Roller pads 82 are respectively provided at both ends of the magnetic roller 8. The roller 98 corresponds to the lower roller 82. After the pressure roller 98 descends, it presses on the roller 82 to provide pressure for the magnetic roller 8 during die cutting. One end of the magnetic roller 8 is also provided with an input gear 83, which drives the magnetic roller 8 to rotate. The input gear 83 can be driven to the roller shaft 80 of the magnetic roller 8. One end of the die-cutting bottom roller is provided with an output gear, which can be driven to the spindle of the die-cutting bottom roller. The rotation of the die-cutting bottom roller drives the output gear to rotate together. The output gear is in corresponding transmission with the (upper) input gear 83. The output gear drives the input gear 83 to rotate, so that the die-cutting bottom roller drives the magnetic roller 8 to rotate.
