[0028] Wherein, driving mechanism includes swing table 51, motor 52 and speed reducer 53, pivot shaft 54 is rotatably connected to the right side of swing table 51, disc cutter 3 is fixed on pivot shaft 54, motor 52 is fixed on the left side of swing table 51, speed reducer 53 is fixed on swing table 51 and connected with motor 52, the output shaft of speed reducer 53 is connected with pivot shaft 54, and disc cutter 3 on pivot shaft 54 can rotate at appropriate speed by motor 52 through speed reducer 53, so as to facilitate the moving speed of workbench 2, realize continuous cutting on stretch film roll.
[0029] Further, the middle shaft 61 is rotatably connected in the middle of the swing table 51, both ends of the middle shaft 61 are fixed on the rack 1, in addition, the rack 1 is fixedly connected with the telescopic cylinder 62 on the lower side of the left end of the swing table 51, the piston rod of the telescopic cylinder 62 is hingedly connected with the hinge rod 63, the other end of the hinge rod 63 is hingedly connected on the left end of the swing table 51, the piston rod is driven to move up and down by the telescopic cylinder 62, so that the swing table 51 can be driven to swing up and down by the hinge rod 63 with the middle shaft 61 as the center, thereby achieving the height position adjusting function of controlling the up and down movement of the disc cutter 3. The swing table 51 and its height adjusting mechanism give the disc cutter 3 flexible adjustment capability, which can not only lift the cutter in the non-working state to facilitate the loading and unloading of the stretch film roll, but also accurately set the cutting depth during work, meeting the diversified processing requirements. This further improves the operation convenience and application range of the equipment.
[0030] The specific structure that the workbench 2 is slidably arranged on the left and right of the rack 1 is that the rack 1 is fixedly connected with the track 71 arranged from left to right on the lower side of the workbench 2, the track 71 is symmetrically provided with two tracks, the upper roller 72 is arranged on the upper side of the track 71, and the lower roller 73 is arranged on the lower side of the track 71, so that the workbench 2 can stably slide on the track 71.
[0031] In the utility model, the workbench 2 is fixedly connected with the hand lever 8, the hand lever 8 enables the operator to directly control the movement of the workbench 2, and the work progress can be adjusted according to the actual situation. Especially when cutting the stretch film in the roll shape, the hand lever 8 can help the operator to accurately control the moving speed of the workbench 2, and ensure that the pre-cutting tooth 31 on the disc cutter 3 can form an ideal pre-cutting on the stretch film roll. It should be noted that the workbench 2 can also be automatically controlled, a lead screw motor can be arranged on the rack 1, a lead screw is connected to the lead screw motor, and a nut seat is fixed on the lower side of the workbench 2 and is in threaded connection with the lead screw, so that the workbench 2 can be driven to move left and right by the lead screw motor. It should be noted that the speed of the workbench moving left and right driven by the lead screw motor and the rotating speed of the disc cutter should be kept synchronous. Since the lead screw motor, the lead screw and the nut seat are commonly used in the art, they are not particularly shown in the drawings.
[0032] The working principle of the utility model is as follows:
[0033] I. Preparation stage:
[0034] First, move the workbench 2 to the rightmost position, and install the completed stretch film roll 9 on the supporting rod 41, then use the limiting cover 43 to fix it, to ensure that the stretch film roll does not slip or rotate during cutting. Preferably, the disc cutter 3 is in the raised position to easily fit the stretch film roll into the supporting rod 41.
[0035] II. Pre-start setup:
[0036] According to the diameter of the stretch film roll and the desired location and depth of the pre-cut, adjust the height of the disc cutter 3 on the swing table 51 using the telescopic cylinder 62 to reach the appropriate cutting position. Then check and confirm that the drive mechanism (motor 52, reducer 53) and the movement system of the workbench 2 are in normal condition, ready for cutting operation.
[0037] III. Cutting operation:
[0038] Start the drive mechanism to begin the slow rotation of the disc cutter 3. Since the disc cutter 3 has multiple pre-cut teeth 31 on its edge, as it rotates, these teeth will sequentially contact the surface of the stretch film roll. The operator holds the hand lever 8 (or through the drive mode of the lead screw motor and lead screw) and smoothly pushes the workbench 2 from right to left according to the rotation speed of the disc cutter 3. The movement speed of the workbench 2 needs to match the rotation speed of the disc cutter 3 to ensure that each pre-cut tooth 31 can accurately cut into the surface of the stretch film roll, forming uniform pre-cuts.
[0039] As the workbench 2 moves, the pre-cut teeth 31 on the disc cutter 3 will cut a series of easily torn pre-cuts directly on the roll-shaped stretch film along the axial direction of the stretch film roll without the need to unroll the stretch film.
[0040] IV. Completion of cutting:
[0041] When the workbench 2 moves to the leftmost position, the entire stretch film roll has completed the pre-cutting. At this time, stop the drive mechanism to stop the rotation of the disc cutter 3. Then use the telescopic cylinder 62 to lift the disc cutter 3 for subsequent removal of the processed stretch film roll. Remove the stretch film roll with pre-cuts and prepare for the processing of the next stretch film roll.
[0042] Key technical points of the above operation:
[0043] 1. Synchronous control: The movement speed of the workbench 2 and the rotation speed of the disc cutter 3 must be kept in sync, which is one of the key factors to ensure the quality of pre-cuts. If they are not synchronized, it may result in uneven or insufficient / overcut pre-cuts.
[0044] 2. Cutting depth adjustment: By adjusting the height of the swing table 51, the depth of the pre-cut teeth 31 cutting into the stretch film roll can be accurately controlled, thereby adapting to stretch film rolls of different thicknesses while avoiding damage to the internal material.
[0045] 3. Safety and stability: The limiting device and the stable workbench 2 sliding structure ensure safety during cutting to prevent accidents and also ensure the straightness and consistency of the cutting path.
[0046] It should be pointed out that the terms such as "front", "back", "vertical", "horizontal", etc. indicated in the utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the protection scope of the utility model.
[0047] The above merely describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
