Description

Technical Field

[0001] This utility model relates to the technical field of accessories for crushers, and in particular to an adjustable blade used in a crusher for raw materials of packaging barrels. Background Technology

[0002] The main raw material of packaging barrels is plastic. During the processing and production process, a crusher is needed to mix and crush the raw materials and their additives to provide high-quality raw materials for subsequent processes.

[0003] The working principle of a shredder is to tear the material into pieces within a high-shear force zone by utilizing the speed difference generated by the rotor's rotation. However, currently available shredders have fixed blade positions, which results in fixed power consumption during operation and thus low energy efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that the blade position is fixed in current market products, which results in fixed power consumption during operation and low energy efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable blade for a raw material crusher for packaging barrels, including a longitudinal drive shaft installed inside the crusher, a plurality of longitudinal flipping grooves symmetrically opened on the outer side of the longitudinal drive shaft, flipping blades being movably connected inside the longitudinal flipping grooves, and an internal control chamber being opened at the connection end of the longitudinal drive shaft corresponding to the flipping blades, and a separate magnetic control drive mechanism being longitudinally arranged inside the internal control chamber.

[0006] The connecting shaft end of the flipping blade is axially fixed in the internal control chamber with an internal worm gear that cooperates with the separate magnetic drive mechanism.

[0007] The split magnetic drive mechanism includes a longitudinal electric drive shaft fixed inside the longitudinal drive shaft, a lateral control gear slidably sleeved on the outside of the longitudinal electric drive shaft, an adjusting ring movably sleeved on the outside of the lateral control gear, an annular electromagnet fixed on the inner side of the inner control chamber, an iron spring connected between the adjusting ring and the annular electromagnet, and a hollow worm gear meshing with the inner worm gear.

[0008] The hollow worm gear is sleeved on the outside of the longitudinal electric drive shaft, and a gap is left between the inner wall of the hollow worm gear and the outer wall of the longitudinal electric drive shaft.

[0009] The upper surface of the hollow worm gear has an annular toothed surface that mates with the lateral control gear.

[0010] A pressure sensor controller for monitoring external pressure is installed on the inner side of the vertically placed flip-top groove.

[0011] The beneficial effects of this utility model are:

[0012] (1) The adjustable blade of the present invention can control the flipping and storage of the blade, and can quickly adjust the external resistance under different working conditions, thereby reducing power consumption and improving energy efficiency ratio.

[0013] (2) The entire control device is integrated inside the longitudinal drive shaft, with high integration and durability;

[0014] (3) The level of intelligence of the entire device is greatly improved by automatic control of external pressure. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Figure 1 This is a schematic diagram of the structure of this utility model.

[0017] Figure 2 This is a partial internal schematic diagram of the present invention. Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Figure 1 and Figure 2 The adjustable blade shown is used in a raw material crusher for packaging barrels. It includes a longitudinal drive shaft 1 installed inside the crusher. A plurality of longitudinal tilting grooves 2 are symmetrically opened on the outer side of the longitudinal drive shaft 1. Tilting blades 3 are movably connected inside the longitudinal tilting grooves 2. An internal control chamber 4 is opened inside the longitudinal drive shaft 1 corresponding to the connecting end of the tilting blades 3. A separate magnetic control drive mechanism 5 is longitudinally arranged inside the internal control chamber 4.

[0021] The longitudinally placed flip-over grooves 2 at the same height are symmetrically opened on both sides of the longitudinally placed drive shaft 1, and the angles of the longitudinally placed flip-over grooves 2 at different heights are different.

[0022] To facilitate adjustment, the end of the connecting shaft of the flipping blade 3 is axially fixed in the internal control chamber 4 with an internal worm gear 6 that cooperates with the separate magnetic drive mechanism 5.

[0023] To facilitate control, the split magnetic drive mechanism 5 includes a longitudinal electric drive shaft 51 fixed inside the longitudinal drive shaft 1, a lateral control gear 52 slidably sleeved on the outside of the longitudinal electric drive shaft 51, an adjusting ring 53 movably sleeved on the outside of the lateral control gear 52, an annular electromagnet 54 fixed on the inner side of the internal control chamber 4, an iron spring 55 connecting the adjusting ring 53 and the annular electromagnet 54, and a hollow worm 56 meshing with the internal worm gear 6.

[0024] When idle, the lateral control gear 52 is separated from the hollow worm gear 56 by the compression of the iron spring 55. Only when it is necessary to control the flipping blade 3, the ring electromagnet 54 is activated, which drives the iron spring 55 to contract. Then, the iron spring 55 drives the lateral control gear 52 to descend and mesh with the upper surface of the central control worm gear 56 through the adjusting ring 53. At this time, the longitudinal electric drive shaft 51 can drive the central control worm gear 56 to rotate.

[0025] To prevent interference, the hollow worm gear 56 is sleeved on the outside of the longitudinal electric drive shaft 51, with a gap between the inner wall of the hollow worm gear 56 and the outer wall of the longitudinal electric drive shaft 51.

[0026] The longitudinal electric drive shaft 51 cannot directly drive the hollow worm gear 56 to rotate; it must be controlled by the lateral control gear 52.

[0027] To facilitate meshing and locking, the upper surface of the hollow worm gear 56 has an annular toothed surface that mates with the lateral control gear 52.

[0028] In order to monitor the external pressure in real time and thus facilitate the control of the magnetic drive mechanism 5 during separation, a pressure sensor controller 7 for monitoring the external pressure is installed on the inner side of the longitudinally placed flipping groove 2.

[0029] When the pressure sensor controller 7 at different heights detects pressure values ​​at different levels, and using the maximum and minimum pressures as calibration, when the pressure is greater than the minimum pressure, the pressure sensor controller 7 will activate the annular electromagnet 54. This electromagnet drives the lateral control gear 52 to mesh with the upper surface of the hollow worm gear 56, thereby controlling the longitudinal electric drive shaft 51 to rotate the hollow worm gear 56 via the lateral control gear 52. Then, the hollow worm gear 56 drives the internal worm wheel 6 to rotate, thereby controlling the tilting blade 3 to tilt outwards and break up the outer droplets. Conversely, when the pressure is less than or equal to the minimum pressure, the reverse rotation is used to control the tilting blade 3 to tilt inwards and retract, reducing energy consumption.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
