Description

Ice shaver structure

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ice water grate structure, and more particularly to a glacier having a worm gear having a rotational resistance for moving a worm shaft up and down.

1 and 3, the components of the patent are assigned the same reference numerals used in the specification of the present invention, and the ice shelf has a vertical worm shaft 11 And an ice pressure tray 14 coupled to the bottom of the worm shaft 11 to control the ice block. The worm shaft 11 is driven by the motor 20 and rotates. The casing 10 includes a concave portion having a lateral receiving groove 15, a shaft rod 16 passing through the concave portion, and a worm gear 18 disposed at an end portion of the shaft rod 16, The worm gear 18 is engaged with the worm shaft 11 and a spring S 1 is mounted on the shaft rod 16. For two parts to be screwed together, if one of the parts is in a relatively fixed state, the other can rotate to produce displacement. In the above-described apparatus, the spring S1 is compressed to generate an elastic pressing force acting on the worm gear 18, so that the worm gear 18 presses the worm shaft 11, The worm gear 18 can not be rotated by such a resistance acting on the worm gear 18. When the worm shaft 11 is driven and rotated by the motor 20, the worm gear 18 for controlling the ice block to be cut by the blade generates up-and-down displacement in the vertical direction to generate ice water .

However, the above-described apparatus uses the elastic force generated by the compression of the spring S1 to cause the worm gear 18 to press the worm shaft 11 to form the resistance, So that the friction generated between the worm shaft 11 and the worm gear 18 can cause wear or damage to the entire apparatus after a long period of use.

According to the above-described principle, the ice block is controlled so as to be scraped by the blade by rotating and lowering the worm shaft 11 to form the ice water, Depends on the remaining amount of the ice block directly related to the descent displacement after the shaft 11 rotates once. That is, the smaller the falling displacement of the worm shaft 11 after one rotation of the worm shaft 11, the smaller the amount of the ice block shaved by the blade and the greater the density of ice water. However, in the above-described apparatus, the worm gear 18 is placed in a fixed state and becomes unable to rotate due to the resistance by the spring S1, so that the downward displacement after the worm shaft 11 rotates once Is constant and equal to the pitch. Therefore, the ordinary ice-making period can not control the descending displacement after the worm shaft 11 rotates once, and the density level of the ice-water can not be changed, and such ice-making period is insufficient in diversity.

Another ice shelf, such as that disclosed in Chinese Utility Model No. M464631, includes a shift rod that is driven by a speed change motor to rotate an ice pressure dish, and when the ice block is placed on an ice clipper platform, And then rotated. The ice block blade located at the bottom of the ice block shaves the ice block to generate ice water, and the generated ice water falls down from the ice water season. However, there are still the following problems in the above-mentioned ice season.

1. The ice pressure platen of the ice water season and the speed change rod are mutually fixed by screws so as to fix the speed change rod without rotation when it is necessary to remove the ice pressure plate from the speed change rod, The ice pressurizing dish must be rotated until the dish is separated from the bottom of the shift rod. Obviously, this process can not be performed quickly, and it is inconvenient to mount and remove the ice pressure plate for the shift rod.

In the prior art, as shown in Fig. 7 and described in the Utility Model, a press block is used to press the ice block to replace the positioning pin for positioning the ice block. However, the positioning pin or the press block has a sharpened end so that when the positioning pin or the press block is used to position the ice block, the positioning pin or the press block pushes the ice pressure plate A certain thickness of ice is left in the final stage of cutting the ice block to prevent the ice block from being damaged by direct contact with the ice-cutting platform during the rotation, resulting in unnecessary waste.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will become more apparent from the following detailed description of an illustrative embodiment thereof, which is to be taken in conjunction with the drawings, in which: Fig.

1, the ice structure includes a base 10, a column 11 erected from the base 10, and a machine head 12 disposed on the column 11, And the machine head 12 further includes a speed change device as shown in Figs. The transmission includes a drive motor 2 provided with a drive gear 20, a worm shaft 3 disposed vertically in parallel to the drive motor 2, and a worm shaft 3 mounted on the bottom of the worm shaft 3 to control the ice block. And the worm shaft 3 has a driven gear 31 which is gear-engaged with the driving gear 20. As a result, the driving motor 2 is driven by the driving gear 20, The worm shaft 3 can be driven and rotated through the driven gear 20 and the driven gear 31. [ The shaft sleeve 32 is provided along the axis of the driven gear 31 and has a shaft hole 33 penetrating the shaft sleeve 32. The key groove 331 is formed in the Is formed on the side surface of the shaft hole (33), and the key portion (34) protrudes from the side surface of the worm shaft (3). When the worm shaft 3 passes through the shaft hole 33 of the driven gear 31, the key portion 34 is built in the key groove 331, and the driven gear 31 and the worm The shaft 3 is integrally coupled and the driven gear 31 drives the worm shaft 3 to rotate the worm shaft 3.

In addition, the threaded end 35 is located at the upper end of the worm shaft 3, and the worm gear 36 is in gear engagement with the threaded threaded end 35, wherein the shaft rod 361 is engaged with the threaded end 35 of the worm gear 36 The end of the shaft rod 361 is pivotally coupled to the support base 121 of the machine head 12 and the other end of the shaft rod 361 is connected to the rotation of the worm gear 36 And a resistance device 4 for providing resistance to resist. The resistive device 4 includes a stopper 40 and a resilient device 41. The end of the stopper 40 is externally mounted on the positioning column 122 of the support base 121, The other end of the worm gear 40 has a through hole 400 and is housed on the shaft rod 361 of the worm gear 36 and adjacent to the shaft surface of the worm gear 36. [ The resilient device 41 is compressed and generates an elastic restoring force acting on the stopper 40. The elastic force acts on the stopper 40 so that the stopper 40 presses the worm gear 36 Thereby increasing the friction between the two parts. Here, the resilient device 41 may be a compression spring enclosed on the shaft rod of the worm gear, and the resilient force drives the stopper so that the stopper is urged in a direction opposite to the worm gear. The resilient device 41 includes a shaft sleeve 411 and a compression spring 410. The shaft sleeve 411 has a shaft hole 361 which is externally mounted on the shaft rod 361, (412). The shaft rod 361 has a key portion 362. The shaft hole 412 of the shaft sleeve 411 has a key groove 413 and the key groove 413 of the shaft sleeve 411, The key portions 362 of the shaft rod 361 are mutually routed so that when the shaft rod 361 rotates, the shaft sleeve 411 is driven and rotated accordingly. The flange 414 also extends from the end of the shaft sleeve 411 and is adjacent the stopper 40. The compression string 410 is encased on the shaft sleeve 411 and the end of the compression spring 410 is pressed against the flange 414 and the other end of the compression spring 410 is connected to the shaft rod 411. [ (42) screwed to the nut (361). The resilient device 41 presses the flange 414 of the shaft sleeve 411 by an elastic force generated by pressing the compression spring 410 so that the shaft sleeve 411 presses the stopper 40, So as to transmit the elastic force to the worm gear 36. The stopper 40 is urged by the spring 410 to urge the worm gear 36 to increase the friction that must be overcome before the worm gear 36 can rotate. That is, the worm gear 36 can not rotate and defines a fixed end with respect to the worm shaft 3. When the worm shaft 3 is rotated by the drive motor 2, the drive gear 20 and the driven gear 31, the worm shaft 3 is moved up and down with respect to the worm gear 36 And the ice pressure tray 6 installed at the bottom of the worm shaft 3 controls the ice block to cut ice blocks into blades to produce ice water.

When the stopper 40 presses the worm gear 36 to provide friction and resistance after a predetermined period of time, the stopper 40 may be worn or damaged and its thickness may be reduced. The stopper 40 is continuously pressurized by the elastic force of the compression spring 410 so that the worm gear 36 is rotated in order to maintain friction and resistance between the stopper 40 and the worm gear 36. [ The stopper 40 can move along the positioning column 122 of the support base 121 so as to maintain the pressurization in the support base 121. [

Further, the present invention can change the density level of iced water. The factor of the ice water season affecting the density level of the iced water belongs to the dropping displacement generated after the warm axis is rotated one turn. The smaller the dropping displacement, the smaller the amount of ice cut from the ice block or the more the density of iced water increases. The present invention can change the density level of the ice water by adjusting the adjustment nut 42 of the elastic device 41. [ 5, to adjust the degree of compression of the compression spring 410 and to change the elastic force provided by the compression spring 410, the adjustment nut 42 is connected to the shaft rod 361 To adjust its position. Therefore, the resistance of the worm gear 36 against the rotation of the worm gear 36 is varied by varying the force of the stopper 40 for pressing the worm gear 36. The elastic force provided by the compression spring 410 becomes smaller and the stopper 40 pushing the worm gear 36 is pressed downwardly 40 is smaller. Accordingly, the worm gear 36 is moved and rotated together with the worm shaft 3, and an idle rotation is formed between the two. As the downward displacement of the worm shaft 3 per rotation decreases, the ice water becomes thicker or denser.

The present invention provides a resistance against rotation of the worm gear 36 to provide a relatively fixed end and act on the stopper 40 to press the worm gear 36 and form a relatively fixed end The worm shaft 3 is moved upward and downward to rotate the worm shaft 3 and the friction generated between the worm gear 36 and the worm shaft 3 To provide a resilient device (41) that acts on the worm gear to press the worm shaft and create friction / resistance, in order to achieve the effect of preventing wear and tear of the entire ice bath by the worm gear. Meanwhile, the above-described improved structure allows the worm gear 36 to be attached to the resilient device 41 so as to change the downward displacement of the worm shaft 3 and the density level of the ice water, Lt; / RTI > can also be adjusted.

When the connecting part 37 is inserted into the insertion hole 631, a positioning element is provided for positioning the connecting part 37 on the shaft base 63, and the connecting part 37 is inserted into the insertion hole 631. [ 631, the connecting portion 37 includes a stop pin 372 inserted into the pin slot 632. When the stop pin 372 is rotated on the worm shaft 3, the ice pressure tray 6 is driven and rotated. In the preferred embodiment, the positioning element is an elastic ring 371 that is extrapolated on the connecting portion 37 for interfering and positioning the shaft base 63 in the insertion hole 631. The first side 61 of the ice pressurizing tray 6 of the preferred embodiment is disposed around the outer edge of the shaft base 63 and is provided to receive an oil stain falling from the top of the shaft base 63 As shown in Fig.

Each cylinder 64 has a vertical post 641 and a conical end 642. The vertical post 641 is coupled into the ice pressurizing tray 6 and the conical end 642 is exposed from the second side 62.

The insertion hole 631 of the shaft base 63 of the ice pressure tray 6 is precisely aligned with the connection portion 37 disposed at the bottom of the worm shaft 3 before cutting the ice block . After the stop pin 372 is precisely aligned with the pin slot 632, the connecting portion 37 is received in the insertion hole 631 of the shaft base 63, The shaft base 63 is interfered and positioned in the insertion hole 631 so that the assembling process of the tray 6 and the connection portion 37 can be completed. On the other hand, if it is necessary to separate the ice pressurizing tray 6 from the connecting portion 37, the ice pressurizing tray 6 is pulled downward by the hand. The downward pulling force is applied to the elastic ring (62) for interfering and positioning the shaft base (63) in the insertion hole (631) to perform the separation process of the ice pressure tray (6) 371).

In an actual application for cutting the ice block, the ice block A is placed in the ice container 5, as shown in Figs. After the ice block A is precisely aligned with the ice pressure tray 6, the worm shaft 3 rotates in the opposite direction to the surface of the ice block A, And descends to press the plurality of columns (64) on the side (62).

The conical end portion 642 which is in contact with the ice block A and disposed at the end of the vertical column end portion 641 is formed in the worm shaft 3, The surface of the ice block A can be quickly rolled when it is pressed downward, and the column 64 is accommodated in the ice block A for a joining effect. Now, the ice block A is driven and rotated by the worm shaft 3, and a blade 51 installed on the bottom of the ice container 5 scoops the ice to generate iced water.
