Description

Technical Field

[0001] This utility model relates to the field of packaging film slitting technology, specifically a packaging film slitting device using a rotating blade. Background Technology

[0002] The rotary blade cutting packaging film slitting device is a specialized piece of equipment that uses rotating blades to slit films. It is mainly used in the packaging industry and is suitable for the efficient cutting of materials such as polyester film, BOPP, and PE.

[0003] To ensure cutting accuracy, save labor costs, and improve production efficiency, a rotary film cutting device (see patent number: 202321655332.4) has been developed. This device includes a mounting base, a film cutting mechanism, and a drive mechanism. The film cutting mechanism includes a positioning component and a cutting blade assembly. The positioning component includes a rotating disk and a guide gear. The guide gear has a gear end and a guide rod end, with the guide rod end connected to the rotating disk to drive its rotation. The rotating disk has an annular positioning groove. The cutting blade assembly includes a positioning seat, a blade box, and a cutting blade. The other end of the cutting blade abuts against the annular positioning groove. The drive mechanism includes a drive unit and a transverse rack. The drive unit drives the transverse rack to move left and right, causing the transverse rack to transmit power to the gear end of the guide gear. This allows the guide gear and the rotating disk to move in tandem. Through the structural design and coordination between the film cutting mechanism and the drive mechanism, automatic cutting is achieved using the weight of the cutting blade and the rotation of the rotating disk, ensuring cutting accuracy, saving labor costs, and improving production efficiency.

[0004] However, in the process of using existing packaging film slitting devices that use rotary cutter discs, the rotating cutter discs will impact or continuously rub against the guide rollers supporting the packaging film when they move up and down. If the force is too large, it will damage the rotating cutter discs and deform their edges, which will easily reduce the flatness of the packaging film after subsequent slitting, causing the slitting packaging film to be scrapped directly after slitting, thus reducing the utilization rate to a certain extent.

[0005] Therefore, a packaging film slitting device using a rotating blade is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a packaging film slitting device that uses a rotating cutter disc to solve the problem of uneven slitting caused by damage to the rotating cutter disc and deformation of its edges.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a packaging film slitting device using a rotary blade, comprising a support frame, wherein a movable hole is provided at the middle position of the top of one end of the support frame, and electromagnetic slide rails are installed on both sides of one end of the support frame and on both sides of the movable hole, and a linkage frame is slidably connected to one end of the two sets of electromagnetic slide rails, and screws extending to the other end of the support frame are provided on both sides of one end of the support frame and on the side of the electromagnetic slide rail away from the movable hole, and a sleeve rod is provided at one end of the support frame and below the movable hole;

[0008] Among them, a motor is installed at one end of the linkage frame and at the end of the movable hole, an electric push rod is installed at the output end of the motor and at one end of the linkage frame, and a rotating cutter head is provided at the output end of the electric push rod;

[0009] The screws are in two sets, and each set of screws has a connecting frame fitted at both ends. A limiting rod that is fixedly connected to the support frame is inserted at the bottom of one end of each pair of connecting frames. A grinding roller is fixed on one side of each pair of connecting frames, and a pressure roller is rotatably connected to the side of the remaining two sets of connecting frames near the rotating cutter disc.

[0010] As a further improvement of this utility model: both sides of one end of the support frame are provided with docking holes, and the screws are rotatably connected to the support frame through the docking holes, and a motor is installed on the other end of the screws and the other end of the support frame.

[0011] As a further improvement of this utility model: the remaining two sets of connecting frames are each provided with a bearing on the side near the rotating cutter head, and the two sets of pressure rollers are rotatably connected to the connecting frame through the bearing.

[0012] As a further embodiment of this utility model: one end of the two sets of screws is provided with a front rotating external thread, and the other end of the two sets of screws is provided with a rear rotating external thread. The top of one end of each of the four sets of connecting brackets is provided with an internal thread hole that matches the front rotating external thread and the rear rotating external thread. The connecting brackets are all threadedly connected to the screws through the internal thread hole, the front rotating external thread, and the rear rotating external thread.

[0013] As a further improvement of this utility model: the bottom of one end of each of the four sets of connecting frames is provided with a movable hole that matches the limiting rod, and the four sets of connecting frames are movably connected to the limiting rod through the movable hole.

[0014] As a further improvement of this utility model: multiple sets of limiting rings are evenly arranged on the outer side of the screw near the support frame, and the number of limiting rings is four sets, with each pair of limiting rings located at both ends of the mating hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Because the front end of the screw is provided with a front rotating external thread and the rear end of the screw is provided with a rear rotating external thread, and the top of each pair of connecting frames is provided with internal thread holes that match the front rotating external thread and the rear rotating external thread, the two adjacent connecting frames can move in the same direction at the same time and directly squeeze the edge of the rotating cutter disc. This allows the grinding roller to grind the rotating cutter disc, making the edge cutting sharper, and the pressure roller to flatten the edge of the rotating cutter disc, ensuring the flatness of the subsequent cutting.

[0017] 2. The pressure roller is rotatably connected to the connecting frame via bearings, which enables it to rotate and flatten, making the flattening operation simpler. The grinding roller is fixedly connected to the connecting frame, making the grinding effect more stable and improving the grinding effect on the edge of the rotating cutter head, thereby increasing the utilization rate.

The embodiments of this utility model will be described below based on its overall structure.

[0026] Please see Figures 1-5 In this embodiment of the present invention, a packaging film slitting device using a rotary blade includes a support frame 1. A movable hole 101 is provided at the middle position of the top of one end of the support frame 1. Electromagnetic slide rails 102 are installed on both sides of one end of the support frame 1 and on both sides of the movable hole 101. A linkage frame 2 is slidably connected to one end of the two sets of electromagnetic slide rails 102. A screw 3 extending to the other end of the support frame 1 is provided on both sides of one end of the support frame 1 and on the side of the electromagnetic slide rails 102 away from the movable hole 101. A sleeve rod 103 is provided at one end of the support frame 1 and below the movable hole 101.

[0027] Among them, a motor 201 is installed at one end of the linkage frame 2 and at one end of the movable hole 101, an electric push rod 202 is installed at the output end of the motor 201 and at one end of the linkage frame 2, and a rotating cutter head 203 is provided at the output end of the electric push rod 202.

[0028] There are two sets of screws 3, and each set of screws 3 has a connecting frame 302 sleeved on both ends. A limiting rod 301 fixedly connected to the support frame 1 is inserted at the bottom of one end of each set of connecting frames 302. A grinding roller 303 is fixed on one side of the two sets of connecting frames 302, and a pressure roller 304 is rotatably connected to the side of the remaining two sets of connecting frames 302 near the rotating cutter head 203.

[0029] like Figures 1 to 5As shown, both sides of one end of the support frame 1 are provided with docking holes, and the screws 3 are rotatably connected to the support frame 1 through the docking holes. The other end of the screws 3 and the other end of the support frame 1 are each equipped with a motor.

[0030] like Figures 1 to 5 As shown, the remaining two sets of connecting frames 302 are each equipped with bearings on the side near the rotating cutter head 203, and the two sets of pressure rollers 304 are rotatably connected to the connecting frame 302 through the bearings.

[0031] like Figures 1 to 5 As shown, one end of each of the two sets of screws 3 is provided with a front rotating external thread, and the other end of each of the two sets of screws 3 is provided with a rear rotating external thread. The top of one end of each of the four sets of connecting brackets 302 is provided with an internal thread hole that matches the front rotating external thread and the rear rotating external thread. The connecting brackets 302 are all threadedly connected to the screws 3 through the internal thread hole, the front rotating external thread and the rear rotating external thread.

[0032] In this embodiment, since the front end of the screw 3 is provided with a front rotating external thread and the rear end of the screw 3 is provided with a rear rotating external thread, and the top of one end of each pair of connecting brackets 302 is provided with an internal thread hole that matches the front rotating external thread and the rear rotating external thread, the two adjacent connecting brackets 302 can move in the same direction at the same time.

[0033] like Figures 1 to 5 As shown, each of the four sets of connecting frames 302 has a movable hole at the bottom of one end that matches the limiting rod 301, and all four sets of connecting frames 302 are movably connected to the limiting rod 301 through the movable hole.

[0034] like Figures 1 to 5 As shown, multiple sets of limiting rings are evenly arranged on the outer side of the screw 3 near the support frame 1, and there are four sets of limiting rings. Each pair of limiting rings is located at both ends of the mating hole.

[0035] In this embodiment, the provided mating hole allows the screw 3 to rotate better along the position and support frame 1, while the provided limiting ring allows the screw 3 to move stably in this position, thereby ensuring the stability of its movement.

[0036] Operating principle: In use, the electromagnetic slide rail 102 generates a surrounding magnetic field under the action of electricity, which directly acts on the linkage frame 2, allowing the linkage frame 2 to move down along the electromagnetic slide rail 102 until it carries the rotating cutter disc 203 to move directly above the packaging film and contact the top of the packaging film. Then, the output end of the electric push rod 202 extends under the action of electricity, thereby pushing the rotating cutter disc 203 forward, moving the rotating cutter disc 203 to a suitable position for subsequent cutting operations. Then, the output end of the motor 201 rotates under the action of electricity, directly carrying the electric push rod 202 to rotate, thereby directly carrying the rotating cutter disc 203 at the output end of the electric push rod 202 to rotate and cut the packaging film sleeved on the outside of the sleeve rod 103. During the cutting process, the rotating cutter disc 203 can directly move the linkage frame 2 down along the electromagnetic slide rail 102 under the action of the electromagnetic slide rail 102, thereby realizing continuous cutting operations on the packaging film.

[0037] When the edge of the rotating cutter head 203 tilts or completely tilts during the cutting process, the motor output end located on the end face of the screw 3 is directly rotated under the action of electricity, directly driving the screw 3 to rotate. Simultaneously, since the front end of the screw 3 is provided with a front rotating external thread and the rear end of the screw 3 is provided with a rear rotating external thread, and each pair of connecting brackets 302 has internal threaded holes at one end that match the front and rear rotating external threads, adjacent connecting brackets 302 can move simultaneously in the same direction, and the corresponding two grinding rollers 303 and two pressure rollers 304 can move in opposite directions. The rotating blade 203 is pressed directly against the edge of the rotating blade 203 by the grinding roller 303, which grinds the rotating blade 203 and makes the edge cut sharper. The edge of the rotating blade 203 is flattened by the pressure roller 304 (and the pressure roller 304 is rotatably connected to the connecting frame 302 through the bearing, which makes the flattening operation simpler. The grinding roller 303 is fixedly connected to the connecting frame 302, which makes the grinding effect more stable and the grinding effect of the edge of the rotating blade 203 better, thereby improving the utilization rate).

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
