Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene film processing, in particular to a polyethylene film slitting device. Background Art

[0002] The PE film, namely the polyethylene film, refers to the film produced with PE particles. The PE film has moisture-proof property and low moisture permeability. According to different manufacturing methods and control means, polyethylene films with different properties such as low density, medium density, high density polyethylene and cross-linked polyethylene can be manufactured. During the production and processing of polyethylene films, it is necessary to slit them according to requirements.

[0003] The utility model patent with the patent publication number CN212075879U discloses a slitting device for polyethylene film production, including a top plate and baffles arranged at both ends of the top plate. The outer side walls of the two baffles are connected to the top side walls of the piston rods of the cylinders through connecting rods. A sliding rod is arranged below the top plate, and both ends of the sliding rod are connected to the inner side walls of the two baffles. The sliding rod is provided with a plurality of threaded grooves in a penetrating manner, and a plurality of clamping mechanisms are sleeved on the outer side wall of the sliding rod. The clamping mechanism is provided with a first through hole perpendicular to the length direction of the sliding rod, and a bolt penetrates through the first through hole and the threaded groove to fix the clamping mechanism on the sliding rod. The clamping mechanism clamps a blade. The baffles and the clamping mechanism are both provided with a plurality of second through holes in the length direction of the sliding rod, and the fixing rod of the fixing mechanism penetrates through the second through holes. This utility model has strong versatility and is convenient to use.

[0004] However, when this structure is actually used, when adjusting the distance between the blades, it is necessary to make fixed cooperation according to the positions of the threaded grooves, and there are intervals between the threaded grooves. Therefore, when adjusting the distance or position between the blades, it cannot be adjusted arbitrarily, resulting in the inability to slit films with any required width. This will not only cause errors in the width of the slit film, but also make the adjustment less convenient because each blade needs to be fixed separately. Therefore, a polyethylene film slitting device that can facilitate the arbitrary adjustment of the distance between the blades and can be fixed synchronously is proposed. Summary of the Utility Model

[0005] The technical problem to be solved by this utility model is to overcome the deficiencies existing in the prior art and provide a polyethylene film slitting device.

[0006] The present utility model is realized through the following technical solutions: A polyethylene film slitting device, including a frame, a hydraulic pump is supported on the top end of the frame, a hydraulic rod is connected to the bottom end of the hydraulic pump, a lifting frame is connected to the bottom end of the hydraulic rod, two sliding cylinders are installed in parallel on the lifting frame, a tightening component is provided at the bottom end inside each sliding cylinder, a locking component coaxial with the sliding cylinder is arranged at the top end of the tightening component, a plurality of sliding components are sleeved on the two sliding cylinders, a cutter is installed at the bottom end of each sliding component, a cross bar is installed on the lifting frame, the cross bar is in sliding fit with the top ends of the respective sliding components, and a scale is provided on the cross bar.

[0007] It can be seen that in the above technical solution, by the operation of the hydraulic pump on the frame, the hydraulic rod contracts, enabling the synchronous lifting and lowering of each cutter, thus facilitating the cooperation between the cutter and the polyethylene film. With the cooperation of the scale on the cross bar, the distance between the sliding components can be read. When adjusting the distance between the cutters, any of the sliding components sleeved on the two sliding cylinders can be slid, and then the distance between the cutters can be adjusted by observing the scale of the scale. After the adjustment is completed, by rotating the locking component, the locking component presses down on the abutting component, causing the abutting component to protrude outside the sliding cylinder and abut against the sliding component, thereby being able to fix each sliding component, and thus realizing the synchronous fixing of the distance between each cutter and enabling the distance between the cutters to be adjusted arbitrarily, thereby improving the accuracy of tool distance adjustment and the accuracy of the slitting size of the polyethylene film.

[0008] Optionally, in a possible implementation manner, a shaft hole is opened inside the sliding cylinder, a first lifting groove is opened at the bottom end of the shaft hole, a second lifting groove is opened at the bottom end of the first lifting groove, the locking component is inserted into the shaft hole, and the tightening component is arranged in the first lifting groove and the second lifting groove.

[0009] It can be seen that in the above technical solution, the first lifting groove and the second lifting groove can guide the lifting of the tightening component and enable the top end of the tightening component to be connected and cooperate with the locking component.

[0010] Optionally, in a possible implementation manner, fixing rings are installed at both ends of the sliding cylinder, shaft sleeves are provided inside each fixing ring, the two shaft sleeves are respectively rotatably connected to both ends of the locking component, and a locking nail connected to the fixing ring is installed at one end of the locking component.

[0011] It can be seen that in the above technical solution, by connecting the shaft sleeves to both ends of the locking component, the locking component can rotate in the shaft hole, and through the installation of the locking nail, the connection between the locking component and the fixing ring can be realized, thereby fixing the locking component.

[0012] Optionally, in a possible implementation manner, the locking assembly includes a shaft rod, the shaft rod is inserted into the shaft hole, and a movable groove is formed on the shaft rod;

[0013] A turntable, the turntable being mounted at one end of the shaft;

[0014] A knob is welded on the turntable.

[0015] It can be seen that in the above technical solution, by rotating the knob, the turntable synchronous shaft is rotated, so that the position of the movable groove is deflected upward. Therefore, during the deflection of the movable groove, the shaft can produce a downward pressure effect on the top of the clamping assembly, thereby increasing the abutment force of the clamping assembly on the sliding assembly, thereby fixing the sliding assembly.

[0016] Optionally, in a possible implementation manner, the tightening assembly includes a connecting rod, and the connecting rod is disposed in the first lifting slot;

[0017] A tightening plate is arranged in the second lifting groove, the top end of the tightening plate is welded to the connecting rod, and the bottom end of the tightening plate is provided with teeth.

[0018] It can be seen that in the above technical solution, during the sliding process of the sliding assembly on the two slide cylinders, the clamping plate is placed in the second lifting groove, and the connecting rod rises from the first lifting groove to the movable groove, so that when the sliding assembly slides and the distance between the cutting tools is adjusted, arbitrary sliding can be achieved, and when the sliding assembly is locked, the connecting rod is pressed downward by rotating the shaft rod, so that the clamping plate is pressed against the sliding assembly, thereby fixing the sliding assembly.

[0019] Optionally, in a possible implementation, the sliding assembly includes a sliding block, the sliding block is sleeved on two sliding cylinders, and a tool is installed at the bottom end of the sliding block;

[0020] Two sliding holes, the two sliding holes are opened on the slider, and the bottom end of the hole wall of each sliding hole is provided with a tooth groove;

[0021] The groove is arranged in the middle of the top of the slider and is slidably connected with the cross bar.

[0022] It can be seen that in the above technical solution, through the tooth grooves opened in the sliding hole, when the clamping plate is pressed down, the teeth at the bottom end of the clamping plate can be inserted into the corresponding tooth grooves, thereby improving the fixation of the slider. At the same time, the opening of the grooves facilitates the sliding cooperation with the horizontal bar and facilitates the reading of the scale.

[0023] Optionally, in a possible implementation manner, the locking assembly includes a shaft rod rotatably connected to the two shaft sleeves, and a motor connected to a fixing ring is mounted on one end of the shaft rod.

[0024] It can be seen that in the above technical solution, by the operation of the motor, the shaft rod can be rotated, so that the fixing of the sliding component by the tightening component is controlled by the motor, and the automatic synchronous fixing of the tool position is realized.

[0025] The beneficial effects of the present utility model are as follows:

[0026] The present utility model can move the sliding components connected to the tops of the respective tools arbitrarily on the sliding cylinder, so that the distance between the tools can be adjusted arbitrarily, thereby improving the accuracy of the slitting size of the polyethylene film;

[0027] Meanwhile, by arranging a scale on the cross bar, it is convenient to assist in adjusting the distance between the tools, improving the convenience and accuracy of distance adjustment;

[0028] And through the cooperation of the tightening component and the locking component, the respective sliding components can be fixed simultaneously, so as to realize the synchronous fixing of the positions of the respective tools and improve the convenience of adjusting the tool distance.
