Ice machine structure

This creation is related to the structure of the ice machine, especially a ice machine that drives the worm up and down with a worm gear with rotational resistance.

As shown in Figures 6 and 7, the conventional ice planer is provided with a worm 6 standing in a casing 5, and a claw disk 60 is attached to the bottom end of the worm 6 for controlling the ice block, and the worm 6 can be subjected to The motor 7 is driven to rotate; on the other hand, a lateral groove 50 is recessed on one side of the housing 5, and a shaft 51 is disposed therein, and a worm wheel 52 is disposed at the end of the shaft 51, wherein the worm wheel 52 is engaged The worm 6 is disposed on the shaft 51 with a spring 53. In the above-mentioned mechanism, the spring 53 is compressed to generate an elastic thrust, if one of the two mutually screwed elements is in a relatively fixed state, the other can be displaced by rotation. The thrust acts on the worm wheel 52 to cause the worm wheel 52 to abut against the worm 6. The worm wheel 52 is in a state of being unable to rotate by the resistance, so that the worm 6 can be generated relative to the worm wheel 52 when the motor 6 is driven to rotate. The lifting displacement in the upper and lower directions can be used to control the ice block to be shaved by the planer.

However, in the above mechanism, the worm wheel 52 forms a resistance against the worm 6 by the elastic force generated by the compression of the spring 53, so that the worm wheel 52 assumes a relatively fixed state, but the worm will be caused. The friction loss between the 6 and the worm wheel 52 will cause damage to the entire mechanism over time.

In addition, the shaved ice is manufactured by using the above principle to rotate the worm 6 rotatively to control the ice block to be shaved by the planer to form shaved ice; and the degree of formation of the shaved ice depends on the ice cube after the worm 6 rotates one turn. The amount of shaving is positively correlated with the amount of downward displacement after the worm 6 is rotated one turn; in other words, the smaller the amount of descending displacement after the worm 6 is rotated one turn, the less the amount of ice is removed by the planer, the manufactured The shaved ice is denser. However, in the above mechanism, the worm wheel 52 is in a fixed state in which it cannot be rotated by the resistance against which the spring 53 is pushed. Therefore, the amount of downward displacement after the worm 6 is rotated one turn is fixed to a pitch distance. According to the above, the conventional ice planer cannot adjust the amount of downward displacement of the worm 6 after one rotation, and cannot change the density of the shaved ice, so that the manufactured shaved ice product lacks various variability.

In view of this, how to improve the above problems is the primary issue that the creative office wants to solve.

Referring to FIG. 1 , the ice machine structure provided by the present invention comprises a base 10 , the base 10 is erected with a pillar 11 , a top 12 is arranged on the top of the pillar 11 , and a transmission is arranged in the nose 12 . The mechanism, and with reference to Figures 2 to 4, the transmission mechanism includes a drive motor 2, which is provided with a driving gear 20, and a worm 3 is disposed upright next to the drive motor 2, and a bottom end is provided with a The claw plate 30 of the ice block is controlled, and the worm gear 3 is provided with a driven gear 31 that meshes with the driving gear 20 for driving the driving motor 2 through the driving gear 20 and the driven gear 31. The worm 3 rotates. In the embodiment, the shaft of the driven gear 31 has a sleeve 32. The sleeve 32 has a shaft hole 33. The shaft hole 33 has a key groove 331 on one side, and one side of the worm 3 is convex. A key portion 34 is provided, and when the worm 3 is inserted through the shaft hole 33 of the driven gear 31, the key portion 34 is correspondingly embedded in the key groove 331, so that the driven gear 31 and the worm 3 are integrated into one body. The driven gear 31 drives the worm 3 to rotate.

The worm 3 is provided with a threaded section 35, and a worm wheel 36 is engaged with the threaded section 35. The shaft of the worm wheel 36 is provided with a shaft 361, and the shaft 361 is pivoted at one end. One of the heads 12 is supported on the seat 121, and the other end is provided with a resistance mechanism 4 for providing the resistance of the worm wheel 36 to rotate. The resistance mechanism 4 includes a stopper 40 and an elastic device 41. The end of the stopper 40 is sleeved on the positioning post 122 of the support base 121, and the other end is provided with a through hole 400 and sleeved on the shaft of the worm wheel 36. The elastic member 41 is compressed to generate an elastic restoring force against the stopper 40 to apply the elastic force to the stopper 40. The stopper 40 is pushed against the worm wheel 36 to increase the friction between the two. Wherein the elastic device, in short, may be a compression spring, which is sleeved outside the shaft of the worm wheel, and which elastically presses the stopper against the worm wheel; and in the structure of the embodiment, The elastic device 41 includes a shaft 411 and a compression spring 410. The shaft 411 has a shaft hole 412 and is sleeved outside the shaft 361. The shaft 361 is provided with a key portion 362 and the shaft of the shaft 411. The hole 412 is provided with a key groove 413. The shaft 411 is engaged with the key portion 362 of the shaft 361 by the key groove 413, so that the shaft 361 can rotate when the shaft 361 rotates, and the shaft 411 is rotated. One end is extended with a flange 414 and abuts against the stopper 40; the compression spring 410 is sleeved outside the shaft cylinder 411 and has one end thereof abutting the flange 414, and the other end is screwed to the shaft Adjusting nut 42 on 361. The elastic device 41 is pressed against the flange 414 of the shaft 411 by the elastic force of the compression spring 410, so that the shaft 411 is pressed against the stopper 40 and transmitted to the worm wheel 36, according to which The stopper 40 is pressed against the worm wheel 36 by the spring 410, so that the frictional force required to rotate the worm wheel 36 is increased. In other words, the worm wheel 36 cannot be rotated to form a fixed relative to the worm 3. When the worm 3 is driven by the driving motor 2 and the driving gear 20 and the driven gear 31, the worm 3 can be displaced in the up and down direction relative to the worm wheel 36 while rotating, and the worm 3 is bottomed. The claw plate 30 of the end controls the ice cubes, and is scraped by a planer to produce shaved ice.

After a period of use, since the stopper 40 abuts against the worm wheel 36 to provide frictional resistance, the stopper 40 is worn to make its thickness thin. However, the stopper 40 is continuously pushed by the elastic force of the compression spring 410, so that the stopper 40 can be moved along the positioning post 122 of the support base 121, thereby continuously abutting the worm wheel 36 for continuous maintenance. Frictional resistance between the moving member 40 and the worm wheel 36.

Further, the creation can vary the degree of the shaved ice produced. The factor of the ice machine affecting the tightness of the manufactured ice is the amount of downward displacement caused by the rotation of the worm. If the amount of the displacement is smaller, the amount of ice scraped by the scraper is less, and the shaved ice is denser. The creation can change the position of the adjustment nut 42 of the elastic device 41 to change the density of the shaved ice. In detail, as shown in FIG. 5, the adjusting nut 42 can be rotated on the shaft 361 to adjust its position, thereby adjusting the degree of compression of the compression spring 410, and the compression spring 410 can be changed. The magnitude of the elastic force; accordingly, the force that the stopper 40 pushes against the worm wheel 36 also changes, and the resistance that the worm wheel 36 needs to overcome is changed. If the adjusting nut 42 is adjusted away from the stopper 40, the elastic force provided by the compression spring 410 becomes smaller, thereby reducing the force of the stopper 40 against the worm wheel 36, so that the worm wheel 36 can be formed with The state in which the worm 3 is moved and rotated causes the relative movement between the two to form a partial idling phenomenon, and reduces the amount of downward displacement generated by the worm 3 per revolution, thereby producing a denser shaved ice.

The present invention uses the elastic structure to act on the worm wheel to push the worm to generate frictional resistance to form a relatively fixed end. The modification is such that the elastic device 41 acts on the stopper 40 to push against the worm wheel 36, thereby generating the resistance of the worm wheel 36 to form a resistance. Relative to the fixed end, the worm 3 can be moved up and down with the rotation, thereby avoiding the friction loss between the worm wheel 36 and the worm 3 and being damaged; on the other hand, by the improvement of the above structure, the elasticity is further adjusted. The resistance provided by the device 41 to the worm gear 36 changes the amount of downward displacement of the worm 3 to change the density of the shaved ice, which makes the shaved ice product manufactured by the present invention more diverse.

However, the disclosure of the above embodiments is intended to illustrate the present invention and is not intended to limit the present invention, so the replacement of equivalent elements should still be within the scope of this creation.

In summary, it can be made clear to the skilled person that the creation can achieve the aforementioned objectives, and it has already met the requirements of the Patent Law and submitted an application according to law.
