Description

Technical Field

[0001] The utility model relates to a cutter mechanism, in particular to a cutter mechanism capable of adjusting the cutting angle. Background Art

[0002] Automated cutting equipment for materials such as foam needs to be equipped with a corresponding cutting mechanism for automated cutting processing. The current automated foam cutting machine uses a flexible blade in its cutting mechanism. The general principle is to treat the flexible blade as a belt, and through the corresponding transmission wheel assembly, the flexible blade is made to circulate clockwise or counterclockwise to form a cutting effect. This traditional cutting mechanism has the following two main shortcomings: First, it is very troublesome to adjust the cutting angle of the blade, and even during the cutting process, the cutting angle cannot be adjusted and the machine must be stopped for adjustment. Second, because a flexible blade like a belt is used, the blade is not strong enough and is easy to break, the maintenance cost is high, and it is also dangerous. Utility Model Content

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0026] See also Figures 1 to 3 The cutter mechanism with adjustable cutting angle provided in this embodiment includes a left mounting base 1, a right mounting base 2, a left and right reciprocating drive assembly 3, a floating joint 4, a first blade clamping sliding shaft 5, a second blade clamping sliding shaft 6, a cutting blade 7, a first sliding sleeve 8, a second sliding sleeve 9, a left electrically controlled rotation angle motor 10 and a right electrically controlled rotation angle motor 11.

[0027] The left and right reciprocating drive assembly 3 includes a drive device 31, a swing wheel 32 and a swing connecting rod 33. The drive device 31 is arranged on the left mounting base 1, the swing wheel 32 is connected to the output end of the drive device 31, one end of the swing connecting rod 33 is pivotally arranged at an eccentric position of the swing wheel 32, and the other end is connected to the floating joint 4.

[0028] In this way, the output end of the driving device can be connected and transferred through the cooperation of the swing wheel and the swing connecting rod, and the floating joint can be used to drive the "first blade clamping sliding shaft, the second blade clamping sliding shaft, and the cutting blade" as a whole to achieve left and right reciprocating cutting motion. It should be noted here that the floating joint is a standard component in the mechanical field. As a transfer connection, it can achieve functions such as angle offset adaptation and rotation adaptation between two components. Here, the floating joint can adapt to the angle offset caused by the swing wheel (the swing wheel and the swing rod are pivotally eccentrically connected).

[0029] The first blade clamping sliding shaft 5 includes a polygonal sliding shaft 51 and a blade clamping portion 52, and the second blade clamping sliding shaft 6 also includes a polygonal sliding shaft and a blade clamping portion;

[0030] The first sliding sleeve 8 is provided with a polygonal through hole adapted to the polygonal sliding shaft 51 of the first blade clamping sliding shaft 5, and the second sliding sleeve 9 is provided with a polygonal through hole adapted to the polygonal sliding shaft of the second blade clamping sliding shaft;

[0031] The polygonal sliding shaft 51 of the first blade clamping sliding shaft 5 is inserted into the polygonal through hole of the first sliding sleeve 8, and the polygonal sliding shaft of the second blade clamping sliding shaft 6 is inserted into the polygonal through hole of the second sliding sleeve 9; the blade clamping portion of the first blade clamping sliding shaft 5 clamps the left end of the cutting blade 7, and the blade clamping portion of the second blade clamping sliding shaft 6 clamps the right end of the cutting blade 7;

[0032] The left electric-controlled rotation angle motor 10 is connected to the first sliding sleeve 8, driving the first sliding sleeve 10 to rotate a set angle, thereby driving the polygonal sliding shaft of the first blade clamping sliding shaft 5 to rotate a set angle; the right electric-controlled rotation angle motor 11 is connected to the second sliding sleeve 9, synchronously driving the second sliding sleeve to rotate a set angle, thereby synchronously driving the polygonal sliding shaft of the second blade clamping sliding shaft 6 to rotate a set angle;

[0033] One end of the floating joint 4 is connected to the swing link 33, and the other end is connected to the polygonal sliding shaft of the first blade clamping sliding shaft 5, so as to adapt to the angular deviation of the swing link and the angular rotation of the polygonal sliding shaft.

[0034] It should be noted that, based on the sleeve-type blade clamping sliding shaft, a floating joint can be used to adapt to rotation, and with the cooperation of the electrically controlled rotation angle motor and the sliding sleeve, the polygonal sliding shaft of the blade clamping sliding shaft can be controllably driven to rotate to a set angle, thereby instantly adjusting the cutting angle of the cutting blade. In other words, the floating joint in the present application is a floating joint that can adapt to angle offset and pivoting. In this way, the drive form of left and right reciprocating vibration cutting can be realized, and in conjunction with the blade angle electrically controlled adjustment structure, efficient cutting of materials such as foam can be achieved, and the cutting angle can be adjusted at any time during the cutting process.

[0035] Specifically, an adjusting screw hole is provided at the tail end portion of the polygonal sliding shaft of the second blade clamping sliding shaft 6, and an adjusting screw 12 and an adjusting spring 13 are provided corresponding to the adjusting screw hole. The adjusting spring is sleeved on the adjusting screw, and one end of the adjusting spring presses against the cap of the adjusting screw, and the other end presses against the second sliding sleeve, so that the adjusting screw forms a buffering and resetting effect on the second blade clamping sliding shaft.

[0036] The whole formed by the first blade clamping sliding shaft, the second blade clamping sliding shaft and the cutting blade has a resetting process during the left and right reciprocating motion. Therefore, the adjusting screw hole, the adjusting screw rod and the adjusting spring form a good buffering and resetting structure, which makes the cutting action and the cutting angle adjustment action run more scientifically and smoothly without any jamming.

[0037] Specifically, the cutting blade is a hard blade or a flexible blade. The cutting blade mechanism with adjustable cutting angle gets rid of the structural form of the annular flexible blade, which is more scientific, reasonable, safe and reliable.

[0038] Specifically, the driving device includes a driving motor and a reducer, which can better adjust and control the frequency speed of the reciprocating motion.

[0039] Specifically, the left mounting base and the right mounting base are connected to each other through a gantry frame to form an integrated structure. The gantry structure is more stable and reliable and eliminates vibration.

[0040] Specifically, the blade clamping part includes an upper clamping block and a lower clamping block, an elastically deformable clamping gap is formed between the upper clamping block and the lower clamping block, and a blade locking screw hole is provided between the upper clamping block and the lower clamping block, so as to facilitate clamping and replacing the blade.
