DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 5 As shown, this specific embodiment adopts the following technical solution: it includes a casing 1, a feeding assembly 2 and a discharge hopper 3, the feeding assembly 2 is penetrated through the inner side of the casing 1, and the discharge hopper 3 is provided at the left opening of the casing 1;

[0026] It also contains:

[0027] Rotating shafts 4, there are two rotating shafts 4, both of which are screwed through the housing 1 through bearings. A motor 5 is fixed to the front wall of the housing 1 by bolts. The output shaft of the motor 5 is connected to the rotating shaft 4 on the upper side. An eccentric cylinder 6 is fixedly sleeved on the rotating shaft 4;

[0028] The rotating sleeve 7 is divided into two parts and is respectively screwed on the two eccentric cylinders 6 through bearings. The left and right sides of the side wall of the rotating sleeve 7 are respectively fixed with a connecting frame 8 and a guide frame 9 by bolts. Two reinforcing ribs 20 are fixed on the side wall of the rotating sleeve 7, and the reinforcing ribs 20 are fixedly connected to the guide frame 9. The reinforcing ribs 20 can improve the structural strength of the connection between the guide frame 9 and the rotating cylinder. The blade 10 is connected to the connecting frame 8 through an assembly mechanism 15;

[0029] There are two fixing plates 11, each of which is fixed in the housing 1 by bolts. Sliders 12 are slidably arranged in the two slide grooves provided on the guide frame 9. Guide rods 13 are fixedly arranged on the slides 12. The guide rods 13 are screwed and passed through the fixing plates 11 by linear bearings.

[0030] Gears 14, there are two gears 14, which are fixedly sleeved on the two rotating shafts 4 respectively, and the gears 14 are located at the rear side of the housing 1. The two gears 14 are meshed with each other. A protective cover 19 is fixedly provided on the rear side wall of the housing 1 by bolts, and the protective cover 19 is provided on the two gears 14. The protective cover 19 can provide protection for the gears 14 and prevent debris from contacting the gears 14 and causing damage or jamming.

[0031] The assembly mechanism 15 comprises:

[0032] The mounting strip 15-1 is fixedly provided on the blade 10 and is movably inserted into a strip groove 16 provided on the connecting frame 8. The two movable grooves 15-4 provided on the mounting strip 15-1 are both movably provided with a movable rod 15-2, and the left end of the movable rod 15-2 is movably provided in a mounting groove 17 provided on the left side wall of the connecting frame 8. The mounting groove 17 is an "L"-shaped structure.

[0033] There are two threaded rods 15-3, which are respectively threaded and inserted into the two movable rods 15-2 through threaded connection. After one end of the threaded rod 15-3 passes through the movable rod 15-2 and the mounting strip 15-1, it is threaded and inserted into the threaded groove opened on the inner wall of the strip groove 16. A rubber pad 18 is fixed on the threaded rod 15-3, and the rubber pad 18 is set to conflict with the side wall of the connecting frame 8. After the threaded rod 15-3 is tightened, the rubber pad 18 will be squeezed and conflict with the connecting frame 8 to generate a large friction force, thereby preventing the threaded rod 15-3 from loosening.

[0034] When the present invention is used, the feeding assembly 2 conveys the masterbatch into the casing 1, and then the motor 5 is started. The motor 5 drives the rotating shaft 4 on one side to rotate, and the rotating shaft 4 drives the eccentric cylinder 6 to rotate eccentrically. Affected by the limiting influence of the slider 12, the guide rod 13 and the fixed plate 11, the rotating sleeve 7 can drive the guide frame 9 and the connecting frame 8 to always maintain a horizontal state and make a cyclic circular movement. During this process, the slider 12 will slide back and forth left and right in the slide groove, and the guide rod 13 will also move up and down reciprocatingly, and the engagement of the two gears 14 will make the two rotating shafts 4 rotate synchronously in opposite directions, so that the two rotating sleeves 7 can be in a relative moving state. When the two connecting frames 8 move to the closest point, the blades 10 on both sides can respectively cut the upper and lower sides of the masterbatch synchronously, and each blade 10 only needs to cut into half the diameter of the masterbatch. By shortening the stroke, the blade 10 can be quickly cut in and out during the masterbatch cutting process.

[0035] When the blade 10 needs to be disassembled, the threaded rod 15-3 can be twisted to move the threaded rod 15-3 to the left and disengage from the thread groove. Then, the threaded rod 15-3 can be held and moved, so that the threaded rod 15-3 drives the movable rod 15-2 to move toward the opening direction of the installation groove 17, and the installation bar 15-1 is disengaged from the strip groove 16, thereby realizing the disassembly of the blade 10. After that, the movable rod 15-2 can be moved toward the opening of the movable groove 15-4 by the threaded rod 15-3, and the movable rod 15-2 is removed from the movable groove 15-4. In the process of disassembling the blade 10, the disassembly of the blade 10 is completed by holding the threaded rod 15-3 and moving it. Therefore, there is no need for the staff to contact the blade 10, reducing the occurrence of safety accidents. At the same time, when disassembling the upper blade 10, because the threaded rod 15-3 can be held, the blade 10 can be supported at all times, which can prevent the upper blade 10 from falling due to the disappearance of the installation limit during the disassembly process.

[0036] After adopting the above structure, the beneficial effects of this specific embodiment are as follows:

[0037] 1. Through the cooperation of the rotating shaft 4, motor 5, eccentric cylinder 6, rotating sleeve 7, connecting frame 8, guide frame 9, fixed plate 11, slider 12, guide rod 13 and gear 14, the two blades 10 can cut the two sides of the masterbatch synchronously, reducing the stroke of the blades 10 cutting into the masterbatch, thereby achieving rapid cutting in and out of the blades 10 and improving the efficiency of cutting the masterbatch;

[0038] 2. The cooperation of the assembly mechanism 15 can improve the safety during the installation or removal of the blade 10.

[0039] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
