Description

Technical Field

[0001] This utility model belongs to the field of die-cutting technology, specifically a paper receiving mechanism for a die-cutting machine. Background Technology

[0002] Die cutting is a processing technology that uses molds or cutting tools to cut materials into specific shapes. It is widely used in many industries such as packaging, electronics, printing, medical, and automotive.

[0003] When a paper product of a certain shape needs to be obtained through a die-cutting device, the paper strip is fed into the die-cutting device at a uniform speed. After the paper strip is die-cut, a take-up mechanism is needed to wind up the remaining paper strip. The take-up mechanism is usually driven by a motor to rotate the shaft and the winding drum mounted on the shaft to wind up the paper strip. However, after working for a period of time, the existing take-up mechanism needs to remove the finished paper roll and the intermediate winding drum, and then install a new winding drum on the shaft. The operation is repeated many times, resulting in a long winding interval and affecting work efficiency.

[0004] Therefore, this utility model provides a paper receiving mechanism for a die-cutting machine. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 3 As shown, a die-cutting machine paper receiving mechanism according to an embodiment of the present invention includes a fixed plate 1; a rotating plate 12 is rotatably connected to the side wall of the fixed plate 1; a pair of motors 13 are fixedly connected to the side wall of the rotating plate 12; a shaft 14 is fixedly connected to the output end of the motor 13; a winding drum 15 is slidably installed in the middle of the shaft 14; a support mechanism is installed on the side wall of the rotating plate 12; a limit mechanism is installed on the side wall of the fixed plate 1; and a cutting mechanism is installed on the side wall of the rotating plate 12. During operation, the end of the paper tape to be wound is first connected to the upper winding drum 15, and then the motor 13 corresponding to this winding drum 15 is started to drive the winding drum 15 to rotate, winding the paper tape. After winding is completed, the limit mechanism is opened to release the rotation restriction on the rotating plate 12, and then the rotating plate 12 is rotated to rotate the wound paper tape to the lower position. As the rotation continues, the middle part of the unwound paper tape will be in another winding drum 15. A turning point occurs at the middle, and after the rotation is completed, the positions of the two take-up drums 15 are reversed. Then, the rotation of the rotating plate 12 is restricted by a limiting mechanism. Subsequently, the unwound paper tape between the two take-up drums 15 is cut by a slitting mechanism. Then, the cut end of the unwound paper tape is connected to the take-up drum 15 located above. After the connection is completed, the corresponding motor 13 is started to rewind. Then, the rewound take-up drum 15 can be removed from the shaft 14, and a new take-up drum 15 can be installed on the shaft 14. Through the above structure, the mechanism for winding is divided into two groups. After one roll of paper tape is finished being wound, the unwound paper tape can be quickly connected to another take-up drum 15. Then, the paper tape can be wound and the finished paper tape can be removed at the same time. The two can be carried out simultaneously without affecting each other, thereby improving work efficiency.

[0025] like Figures 1 to 4As shown, the support mechanism includes a fixed rod 2, a connecting rod 21, a locking block 22, a pull rope 23, a pull rod 24, a connecting plate 25, a plug rod 26, and a first spring 27. The fixed rod 2 is provided in pairs and fixedly connected to the side wall of the rotating plate 12. The connecting rod 21 is detachably installed in the middle of the fixed rod 2. The locking block 22 is slidably connected to the inside of the connecting rod 21. The first spring 27 is disposed inside the connecting rod 21, and one end of the first spring 27 abuts against the side wall of the locking block 22. The pull rod 24 is fixedly connected to the side wall of the locking block 22. On the wall; connecting plate 25 is fixed to the other end of pull rod 24; insert rod 26 is fixed to the top of connecting rod 21; insert rod 26 is rotatably connected to the middle of connecting plate 25; during operation, after the new take-up drum 15 is inserted into the middle of shaft 14, connecting rod 21 is inserted into fixed rod 2, and at the same time, the end of insert rod 26 is inserted into the hole at the end of shaft 14. As connecting rod 21 is fully inserted into fixed rod 2, locking block 22 will be inserted into the hole in the middle of fixed rod 2 under the elastic force of first spring 27. This makes it difficult for the connecting rod 21 to move. At this point, the fixed rod 2, connecting rod 21, connecting plate 25, and insert rod 26 can support the end of the shaft 14, making the rotation of the shaft 14 more stable. When it is necessary to remove the winding drum 15 (which has completed its winding operation) from the middle of the shaft 14, pull the pull rod 24 to pull the locking block 22 via the pull rope 23, causing the locking block 22 to disengage from the hole in the middle of the fixed rod 2. Then, pull the connecting rod 21 to remove it from inside the fixed rod 2. The connecting plate 25 and the insert rod 26 no longer obstruct the removal of the winding drum 15, thereby allowing the winding drum 15 and the completed paper roll to be removed. Through the above structure, the end of the shaft 14 can be supported during the winding process, making the rotation of the shaft 14 more stable and reducing the occurrence of errors in the paper tape winding operation. When it is necessary to remove the completed paper tape, the connecting plate 25 and the insert rod 26 can be easily and quickly removed, reducing the impact on the removal operation.

[0026] like Figures 1 to 2 As shown, a pair of slots 3 are provided in the middle of the rotating plate 12; the limiting mechanism includes a fixed seat 31, a second spring 32, and a limiting block 33; the fixed seat 31 is fixed to the side wall of the fixed plate 1; the second spring 32 is fixed to the inside of the fixed seat 31; the limiting block 33 is slidably connected to the middle of the fixed seat 31; during operation, when it is necessary to rotate the rotating plate 12 to change the position of a pair of winding drums 15, the limiting block 33 is pulled to disengage from one slot 3, thereby releasing the rotation restriction on the rotating plate 12. After the rotating plate 12 has completed rotation, the limiting block 33 is released so that the limiting block 33 is inserted into the other slot 3 under the elastic force of the second spring 32, thereby continuing to restrict the rotation of the rotating plate 12. Through the above structure, the rotation state of the rotating plate 12 can be easily restricted and the restriction can be released, making it difficult for the rotating plate 12 to rotate during the winding operation.

[0027] like Figures 1 to 5 As shown, the cutting mechanism includes a movable seat 4 and blades 41. The movable seat 4 is slidably connected to the side wall of the rotating plate 12 and located between a pair of fixed rods 2. A pair of blades 41 are provided and fixed to both sides of the movable seat 4 respectively. During operation, when a section of winding is completed, the rotating plate 12 is rotated to move the winding drum 15 carrying the paper roll to the lower position. At this time, the unwound paper strip will be placed on another winding drum 15. Then, the movable seat 4 is slid to drive the blades 41 to move, and the blades 41 cut the paper strip between the paper roll and the other winding drum 15. With the above structure, the paper strip can be easily cut after a section of paper strip is completed, which improves the ease of use of the device and makes it unnecessary to place the blades randomly in the workplace, thus improving workplace safety.

[0028] like Figures 1 to 3 As shown, a guide rod 51 is slidably connected to the middle of the connecting plate 25; a stop rod 5 is fixedly connected to the end of the guide rod 51; an adjusting bolt 52 is rotatably connected to the side wall of the stop rod 5; the adjusting bolt 52 is threadedly connected to the middle of the connecting plate 25; during operation, when winding paper tapes of different widths, a winding drum 15 of corresponding length can be selected and installed on the shaft 14, and when the connecting rod 21 is installed, the stop rod 5 is fitted into the middle of the shaft 14. After the connecting rod 21 is installed, the adjusting bolt 52 is rotated to adjust the position of the stop rod 5, so that the stop rod 5 abuts against the end of the winding drum 15. Thus, when winding the paper tape, the stop rod 5 and the rotating plate 12 limit the two sides of the paper tape, so that the paper tape can be wound more evenly in the middle of the winding drum 15. Through the above structure, obstacles can be set at the edges of paper tapes of different widths, so that when the paper tape is wound into a paper roll, the paper roll deviation is reduced, which may cause the paper roll to detach from the winding drum 15.

[0029] like Figures 1 to 5 As shown, a first magnet 6 is fixedly connected to the middle of the movable seat 4; a pair of fixed rods 2 are fixedly connected to a second magnet 61 on the side facing the movable seat 4. During operation, after the sliding movable seat 4 drives the blade 41 to cut the paper tape, the movable seat 4 is slid between the pair of fixed rods 2. Then, the movable seat 4 will be difficult to continue moving due to the mutual attraction between the first magnet 6 and the second magnet 61, so that the blade 41 will not easily move when the rotating plate 12 rotates. With the above structure, the blade 41 is difficult to slide when the rotating plate 12 is rotated, thereby improving the safety of the device.

[0030] like Figure 5As shown, the edge of the blade 41 is serrated. When cutting the paper tape with the blade 41, compared with the flat-edge blade 41, which requires gradually applying pressure to the contact point during cutting to cut the paper tape, the serrated blade 41 only needs to slide the moving seat 4 towards the paper tape. The multiple sharp teeth on the edge of the blade 41 will easily pierce the middle of the paper tape and then cut the paper tape, making the cutting operation more convenient.

[0031] During operation, the end of the paper tape to be wound is first connected to the upper winding drum 15. Then, the motor 13 corresponding to the winding drum 15 is started to drive the winding drum 15 to rotate and wind the paper tape. After winding is completed, the limiting mechanism is opened to release the rotation restriction on the rotating plate 12. Then, the rotating plate 12 is rotated to rotate the wound paper tape to the lower position. As the rotation continues, the middle of the unwound paper tape will turn at the middle of the other winding drum 15. After the rotation is completed, the positions of the two winding drums 15 are reversed. The limiting mechanism is then used to restrict the rotation of the rotating plate 12. Then, the cutting mechanism is used to cut the unwound paper tape between the two winding drums 15. Finally, the cut end of the unwound paper tape is connected to the upper winding drum 15. Connect the drum 15, and then start the corresponding motor 13 to wind it up. Afterward, remove the wound drum 15 from the shaft 14 and install a new wound drum 15 on the shaft 14. After inserting the new wound drum 15 into the middle of the shaft 14, insert the connecting rod 21 into the fixed rod 2, and simultaneously insert the end of the insert rod 26 into the hole at the end of the shaft 14. As the connecting rod 21 is fully inserted into the fixed rod 2, the locking block 22 will be inserted into the hole in the middle of the fixed rod 2 under the elastic force of the first spring 27, making it difficult for the connecting rod 21 to move. At this time, the fixed rod 2, connecting rod 21, connecting plate 25, and insert rod 26 can support the end of the shaft 14, making the rotation of the shaft 14 more stable. When it is necessary to complete the winding... When the winding drum 15, which is in the winding operation, is removed from the middle of the shaft 14, the pull rod 24 is pulled to pull the locking block 22 through the pull rope 23, causing the locking block 22 to disengage from the hole in the middle of the fixing rod 2. Then, the connecting rod 21 is pulled to remove the connecting rod 21 from inside the fixing rod 2, so that the connecting plate 25 and the insert rod 26 no longer obstruct the removal of the winding drum 15, thereby removing the winding drum 15 and the completed paper roll. When it is necessary to rotate the rotating plate 12 to change the position of a pair of winding drums 15, the limiting block 33 is pulled to disengage from one of the slots 3, thereby releasing the rotation restriction on the rotating plate 12. After the rotating plate 12 has completed its rotation, the limiting block 33 is released, allowing the limiting block 33 to insert into the other slot 3 under the elastic force of the second spring 32. The rotating plate 12 continues to be restricted from rotation. When a section of winding is completed, rotating the rotating plate 12 moves the winding drum 15 carrying the paper roll to the lower position. At this time, the unwound paper strip will be placed on another winding drum 15. Then, the sliding moving seat 4 drives the blade 41 to move, and the blade 41 cuts the paper strip between the paper roll and the other winding drum 15. When winding paper strips of different widths, a winding drum 15 of the corresponding length can be selected and installed on the shaft 14. When the connecting rod 21 is installed, the stop rod 5 is fitted into the middle of the shaft 14. After the connecting rod 21 is installed, the adjusting bolt 52 is rotated to adjust the position of the stop rod 5 so that the stop rod 5 abuts against the end of the winding drum 15. Thus, when winding the paper strip,The paper tape is limited on both sides by the stop bar 5 and the rotating plate 12, allowing the paper tape to be wound more evenly in the middle of the winding drum 15. After the sliding seat 4 drives the blade 41 to cut the paper tape, the sliding seat 4 is then slid between a pair of fixed rods 2. The sliding seat 4 then becomes difficult to move further due to the mutual attraction between the first magnet 6 and the second magnet 61, thus preventing the blade 41 from easily moving when the rotating plate 12 rotates.
