[0002] Packaging film mainly refers to the film used for packaging items, usually including polyethylene film, biaxially oriented polyester, BOPP film and CPP film, etc., which are mainly used for packaging food, medicine and textiles.

[0003] Patent document CN213918572U discloses a packaging material film cutting stand, comprising a fixed plate, a support frame, a cutting plate, a chute, and a fixing groove. The support frame is movably connected to the upper surface of the fixed plate, the cutting plate is fixedly connected to the middle of the upper surface of the fixed plate by screws, the chute is located inside the fixed plate, and the fixing grooves are symmetrically arranged on the left and right sides of the chute.

This utility model allows the spacing between the support frame and the cutting plate to be adjusted, preventing the cut film from being too short and unable to be reeled onto the support frame, thereby improving the flexibility of the cutting stand during use.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned solutions lack a mechanism for quickly disassembling and assembling the packaging film roll during actual use, which brings inconvenience to the subsequent loading and unloading of the packaging film. Utility Model Content

[0005] The utility model discloses a cutting device for packaging film production, aiming to solve the technical problem of lack of a mechanism for quickly disassembling and assembling a packaging film roll, which causes inconvenience in subsequent loading and unloading of the packaging film.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A cutting device for packaging film production comprises a base, wherein a cutting unit and a packaging film conveying unit are respectively provided on the upper surface of the base, and a feeding mechanism and a tension adjustment mechanism are respectively provided on the upper surface of the base;

[0008] The loading mechanism includes two support frames fixedly mounted symmetrically on the upper surface of the base, and a card slot is provided on the left surface of the two support frames. The two support frames are provided with winding rollers through the card slots, and the packaging film body is wound on the surface of the winding rollers. The inner top wall of the card slot is provided with a mounting groove, and the interior of the mounting groove is provided with a card block extending to the interior of the card slot. The upper surface of the support frame is provided with a sliding opening that penetrates into the interior of the mounting groove, and the inner wall of the sliding opening is slidably connected to an operating rod fixedly connected to the upper end of the card block. The surface of the operating rod located inside the mounting groove is provided with a spring, and the two ends of the spring are respectively fixedly connected to the inner top wall of the mounting groove and the upper end of the card block.

[0009] In a preferred solution, the inner wall of the slot is provided with two symmetrical slot bodies, the inner front wall and the inner rear wall of the slot body are fixedly connected with a connecting rod, and the surface of the connecting rod is rotatably connected with a sliding sleeve.

[0010] The provision of the sliding-assisting sleeve can assist in sliding when the winding roller rotates in the card slot, thereby ensuring smooth discharge of the packaging film body on the subsequent winding roller surface.

[0011] In a preferred embodiment, the tension adjustment mechanism includes a mounting column fixedly mounted on the upper surface of the base, an adjustment groove is provided on the front of the mounting column, a threaded rod is vertically arranged inside the adjustment groove, a threaded block is threadedly connected to the surface of the threaded rod, a support rod is fixedly mounted on the front of the threaded block, and a rotating sleeve is provided on the surface of the support rod.

[0012] In a preferred solution, guide sliders are provided on both side surfaces of the threaded block, and guide sliding grooves for the guide sliders to slide are provided on both side inner walls of the adjustment groove.

[0013] Under the guidance of the guide slider, the threaded block can drive the support rod and the rotating sleeve to move up and down through the rotation of the threaded rod, and the upward movement of the rotating sleeve can support the packaging film body to strengthen its opening and avoid wrinkles due to loosening of the packaging film body.

[0014] In a preferred solution, a transmission opening penetrating into the adjustment slot is formed at the upper end of the mounting post, and an inner wall of the transmission opening is rotatably connected to a rotating rod fixedly connected to the upper end of the threaded rod.

[0015] By setting the rotating rod, the rotating rod can be rotated to drive the threaded rod to rotate, thereby achieving a transmission effect.

[0016] In a preferred solution, two symmetrical guide rods are fixedly mounted on the upper surface of the base, two symmetrical mounting rods are fixedly mounted on opposite surfaces of the two guide rods, and guide sleeves are sleeved on the surfaces of the mounting rods.

[0017] The setting of the guide sleeve can play a role of limiting and guiding the packaging film body, so that it can smoothly enter the interior of the cutting unit.

[0018] As can be seen from the above, the cutting device for packaging film production provided by the present invention has the following technical effects.

[0019] First: Place the winding roller with the packaging film body wound on it on the support frame through the card slot frame, and push the card block into the card slot under the action of the spring to restrict the winding roller. When the winding roller needs to be replaced or disassembled, pull the operating lever to drive the card block to retract into the installation slot. The winding roller can be removed without the restriction of the card block, thereby providing convenience for the loading and unloading work of the device.

[0020] Second: When the tension of the packaging film body needs to be increased, the rotating rod is rotated to drive the threaded rod to rotate. Under the rotation of the threaded rod, the threaded block drives the support rod and the rotating sleeve to move upward, so that the support rod and the rotating sleeve support the packaging film body to achieve the purpose of increasing its tension and avoiding the packaging film body from loosening or wrinkling due to too little tension.
