Description

Technical Field

[0001] This utility model relates to the field of rewinding and slitting machine technology, specifically a rewinding and slitting machine with a self-locking function. Background Technology

[0002] A rewinding and slitting machine is a piece of equipment used for processing roll materials. It is mainly used for cutting, slitting, and rewinding roll materials such as paper, plastic film, and aluminum foil.

[0003] Some rewinding and slitting machines lack a self-locking function, which means that if the machine stops or the power is cut off during production, the roll will continue to rotate due to inertia, causing the material to loosen and fall off, which may injure operators or damage the equipment. Furthermore, the unlocked roll material may rebound quickly (such as elastic film), causing safety accidents. This poses certain operational risks and limits its applicability. Utility Model Content

[0004] The purpose of this invention is to provide a rewinding and slitting machine with a self-locking function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rewinding and slitting machine with a self-locking function, comprising a rewinding and slitting machine body, wherein a rewinding and slitting machine body is provided with a rewinding shaft at its inner end, and further comprising a self-locking mechanism provided at the top of the rewinding and slitting machine body;

[0006] The self-locking mechanism includes a drive motor, a movable cavity, a screw, a movable sleeve, a transmission arm, a rotating shaft, and a locking plate. A set of drive motors is provided on the top surface of the rewinding and slitting machine body corresponding to the position of the roll shaft. A set of movable cavities is provided on the top surface of the rewinding and slitting machine body corresponding to the position of the drive motors. A set of screws is connected to the middle of the movable cavity. A set of movable sleeves is connected to the outside of the screws. A set of transmission arms is provided at the front, rear, and bottom ends of the movable sleeves. A set of rotating shafts is provided on the top surface of the rewinding and slitting machine body corresponding to the position of the movable cavity. Two sets of locking plates are connected to the outside of the rotating shafts.

[0007] Preferably, both sets of locking plates have a sliding groove in the middle, and the bottom surfaces of both sets of locking plates are provided with a friction layer at the ends that are far apart from each other.

[0008] Preferably, the bottom ends of the left and right sets of transmission arms extend through into the slide groove and are connected to a set of extension rods.

[0009] Preferably, the ends of the locking plates that are far apart from each other are all bent downwards.

[0010] Preferably, the movable cavity is inverted "Y" shape.

[0011] Preferably, the movable sleeve is square, and its inner end is provided with an internal threaded hole corresponding to the screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The self-locking mechanism, located at the top of the rewinding and slitting machine, includes components such as a drive motor, a movable cavity, a screw, a movable sleeve, a transmission arm, a rotating shaft, and a locking plate. The drive motor rotates the screw within the movable cavity. The movable sleeve, located on the outside of the screw, moves up and down. The locking plate is linked to the transmission arms at the front and rear ends of the movable sleeve, allowing it to fit against the outside of the roll for locking. The two sets of locking plates improve the locking stability of the roll and are adaptable to rolls of different sizes, providing a good locking effect and strong practicality.

Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1 This utility model provides a rewinding and slitting machine with a self-locking function, including a rewinding and slitting machine body 1, a roll 2 provided at the inner end of the rewinding and slitting machine body 1, and a self-locking mechanism 3 provided at the top of the rewinding and slitting machine body 1.

[0020] Please see Figure 2-3This utility model provides a rewinding and slitting machine with a self-locking function. The self-locking mechanism 3 includes a drive motor 31, a movable cavity 32, a screw 33, a movable sleeve 34, a transmission arm 35, a rotating shaft 36, and a locking plate 37. A set of drive motors 31 is installed on the top surface of the rewinding and slitting machine body 1 corresponding to the position of the roll 2. A set of inverted "Y"-shaped movable cavities 32 is opened at the top of the rewinding and slitting machine body 1 corresponding to the position of the drive motors 31. A set of screws 33 is rotatably connected to the middle of the movable cavity 32. The bottom end of the drive shaft of the drive motor 31 is connected to the top of the screws 33. The screw 33 is fixedly connected to the end and can drive the screw 33 to rotate. A set of movable sleeves 34 are sleeved on the outside of the screw 33. The movable sleeves 34 are square and have internal thread holes corresponding to the screw 33 at their inner ends. The rotation of the screw 33 can drive the movable sleeves 34 to move up and down. A set of transmission arms 35 are hinged to the front, back and bottom ends of the movable sleeves 34. A set of rotating shafts 36 are fixedly connected to the top surface of the rewinding and slitting machine body 1 at the position corresponding to the movable cavity 32. Two sets of locking plates 37 are hinged to the outside of the rotating shafts 36. The two sets of locking plates 37 can rotate around the rotating shafts 36.

[0021] Please see Figure 2-3 This utility model provides a rewinding and slitting machine with a self-locking function. The middle of the front and rear locking plates 37 are provided with a sliding groove 371, and the bottom surfaces of the two locking plates 37 are provided with a friction layer 372 at the ends that are far apart from each other. The friction layer 372 is made of rubber, which can improve the friction and enhance the locking effect. The ends of the locking plates 37 that are far apart from each other are bent downward, which is more conducive to contacting the roll 2 and locking the roll 2.
