Description

TECHNICAL FIELD

[0001] The utility model relates to orange squeezer technical field especially relates to a lifting type orange squeezer. BACKGROUND

[0002] In the design and manufacturing process of the conventional orange squeezer, the transmission shaft is often relied on to realize its lifting function. As an important component in mechanical transmission, the transmission shaft undertakes the key task of transmitting power from one component to another. However, in the working process of the orange squeezer, the transmission shaft needs to drive various components to work cooperatively. When the length of the transmission shaft is too long, the transmission shaft is prone to flexural deformation when receiving materials. In the rotation process, with the increase of the length, the offset of the center of mass will be further amplified, which not only affects the precision and stability of the transmission shaft, but also may cause friction and interference with other components, increasing the friction loss during rotation, and thus affecting the transmission efficiency of the whole machine. Secondly, the excessive length of the transmission shaft makes its mass distribution more complex, making it difficult to achieve the ideal balance state. This not only leads to the increase of equipment vibration and noise, but also may cause more serious mechanical failures, thereby increasing the difficulty of dynamic balance correction. In addition, the excessive length of the transmission shaft increases its moment of inertia, resulting in an increase in the power and time required for the equipment to start, stop or change speed, reducing the response speed and flexibility of the orange squeezer.

For the direction words appearing in the utility model, it is to better explain the characteristics of features and the relationship between features, it should be understood that when the display direction of the utility model changes, the direction of the characteristics of features and the relationship between features also changes accordingly, therefore, the direction word does not constitute the absolute limitation of the characteristics of features and the relationship between features in space, and only plays a relative limiting role.

[0026] The utility model provides a kind of lifting type orange squeezing machine, such as Figures 1 to 7As shown, it comprises a body 1, a juicing head 2, a motor 3, an output gear 4, an output shaft 5, a shaft coupling 6, a transmission shaft 7 and a sleeve 8 are arranged in the body 1; the output shaft 5 is fixedly connected at the center of the output gear 4, and it is easy to understand that the fixed connection means that the output shaft 5 can only rotate with the output gear 4, but cannot move up and down; the cross sections of the output shaft 5 and the transmission shaft 7 are both arranged as non-circular shapes, and the inner hole of the shaft coupling 6 is also arranged as a non-circular shape; one end of the shaft coupling 6 is sleeved on the output shaft 5 and can move up and down relative to the output shaft 5, and the other end of the shaft coupling 6 is fixedly connected to the transmission shaft 7; specifically, the transmission shaft 7 and the shaft coupling 6 can be fixedly connected by screws, rivets, bolts and the like, so that it is easier to disassemble and replace during maintenance, greatly reducing maintenance costs and time; the transmission shaft 7 is threadedly connected with the sleeve 8, and the end of the transmission shaft 7 away from the output shaft 5 passes through the sleeve 8 and is connected with the juicing head 2; the sleeve 8 is fixedly connected in the body 1, the motor 3 drives the output gear 4 to rotate, the output shaft 5 rotates with the output gear 4, and the transmission shaft 7 rotates with the output shaft 5 through the shaft coupling 6 while moving up and down through the threaded connection with the sleeve 8, so as to drive the juicing head 2 to move up and down and rotate at the same time.

[0027] Based on the above structure, the output shaft 5 and the transmission shaft 7 are connected by the shaft coupling 6, effectively achieving smooth transmission between the output shaft 5 and the transmission shaft 7 while shortening the length of the transmission shaft 7, which can significantly reduce the risk of flexural deformation of the parts, not only improving the transmission efficiency, but also prolonging the service life of the transmission components; at the same time, the vibration and noise generated during rotation are relatively small, more easily achieving dynamic balance, reducing the moment of inertia, thereby shortening the response time of the equipment and improving the juicing efficiency.

[0028] In the present embodiment, the end of the transmission shaft 7 away from the output shaft 5 is provided with a plurality of threaded segments, and the diameter of the threaded segments is greater than the diameter of the transmission shaft 7, and at least two threaded segments are threadedly connected with the sleeve 8 during the up and down movement of the transmission shaft 7. Through the above structural design, the stability of the transmission shaft 7 during transmission can be ensured, and the segmented design can reduce the friction generated during thread rotation, thereby improving the transmission efficiency. Of course, it is also possible to set the threaded segments as a continuous whole, which should also fall within the protection scope of the present application. In addition to setting the threaded segments as segmented, the threaded segments can also be set as intermittent, which can also achieve the purpose of reducing friction.

[0029] In the embodiment, the body 1 is provided with an upper limit switch 9 and a lower limit switch 10, and the coupling tube 6 is provided with a trigger block 61, and the upper limit switch 9 and the lower limit switch 10 can be triggered by the trigger block 61. When the trigger block 61 of the transmission shaft 7 triggers the lower limit switch 10 to rotate forward and rise, the trigger block 61 of the transmission shaft 7 triggers the upper limit switch 9 to rotate reversely and descend; conversely, when the trigger block 61 of the transmission shaft 7 triggers the lower limit switch 10 to rotate reversely and rise, the trigger block 61 of the transmission shaft 7 triggers the upper limit switch 9 to rotate forward and descend, so as to realize the continuous lifting of the transmission shaft 7.

[0030] In the embodiment, the transmission shaft 7 is provided with a first threaded section 71, a second threaded section 72 and a third threaded section 73 at one end away from the output shaft 5; when the upper limit switch 9 is triggered by the trigger block 61, the first threaded section 71 and the second threaded section 72 are still threadedly matched with the sleeve 8; when the lower limit switch 10 is triggered by the trigger block 61, the second threaded section 72 and the third threaded section 73 are still threadedly matched with the sleeve 8. Through the above structural design, the stability during transmission can be ensured.

[0031] In the embodiment, the transmission shaft 7 is sleeved with a jacking member 11 at one end close to the juicing head 2 and abuts against the jacking member 11, and the juicing head 2 is sleeved on the jacking member 11; the body 1 is provided with a residue separation disc 12, which can be supported by the jacking member 11 and is fixed circumferentially relative to the body 1. It is easy to understand that the residue separation disc 12 cannot rotate with the juicing head 2, but can lift and descend with the juicing head 2, so as to avoid that the residue separation disc 12 rotates and rubs the orange peel when the juicing head 2 rises to the highest position, which causes the orange juice to be bitter.

[0032] In the embodiment, the body 1 is further provided with a juice receiving disc 13, the juice receiving disc 13 is provided with a non-circular guide column 131, the residue separation disc 12 is provided with a non-circular guide pipe 121, the non-circular guide pipe 121 is sleeved on the non-circular guide column 131 and can move up and down relative to the non-circular guide column 131. The non-circular guide column 131 and the non-circular guide pipe 121 realize the function that the residue separation disc 12 can only lift and descend but not rotate, which is simple and convenient.

[0033] In the embodiment, the body 1 is further provided with an overflow disc 14, and the overflow passages 15 are formed between the residue separation disc 12 and the juice receiving disc 13, between the juice receiving disc 13 and the jacking member 11, and between the overflow disc 14 and the juice receiving disc 13. Specifically, the juice receiving disc 13 is hinged with a juice receiving nozzle, when the liquid in the juice receiving disc 13 rises to the maximum value and the juice receiving nozzle is not opened in time, the liquid will flow from the overflow passage 15 between the residue separation disc 12 and the juice receiving disc 13 to the overflow passage 15 between the juice receiving disc 13 and the jacking member 11, and finally flow out of the body 1 from the overflow passage 15 between the overflow disc 14 and the juice receiving disc 13, so as to avoid that the liquid flows back to the inside of the body 1, and ensure the safety of the orange juicer.

[0034] In the embodiment, the coupling pipe 6 is provided with a shear ring 62 between the output shaft 5 and the transmission shaft 7. When the juicer head 2 is stuck by food and the motor 3 continues to run, the shear ring 62 can be disconnected, effectively reducing the burning of the motor 3.

[0035] In the embodiment, the machine body 1 is also provided with a mounting seat 16, and the contact between the output gear 4 and the mounting seat 16 is made of POM plastic. The POM plastic has outstanding wear resistance, effectively improving the durability and service life of the equipment.

[0036] In summary, the lifting type orange squeezer can solve the problems of easy deformation of parts, increased difficulty of dynamic balance correction and increased rotational inertia caused by the long transmission shaft of the existing orange squeezer.

[0037] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited to the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
