In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0033] The utility model proposes a rolling structure. In order to facilitate understanding of the implementation principle of the rolling structure proposed by the utility model, the juice extraction process of the juice extractor is first introduced. Figure 6 As shown, the juicer is provided with a frame 400, on which a pressure plate 430 for receiving fruits and vegetables is provided, a crushing structure is provided above the pressure plate 430, the pressure plate 430 is provided with filter holes, and a juice storage box 420 is provided below the rolling plate 300, the filter holes are used to drain the juice squeezed by the crushing structure to the juice storage box 420, the juicer also includes a first power device 410 for driving the pressure plate 430 to move toward the crushing structure, or, includes the first power device 410 for driving the crushing structure to move toward the pressure plate 430, and in addition, the juicer is further provided with a driving member 100 on the frame 400 for driving the rolling plate 300 to move. During the juicing process of the present embodiment, the user places the fruits and vegetables on the pressure plate 430. First, the first power device 410 pushes the pressure plate 430 to move toward the crushing structure. The position of the crushing structure relative to the frame 400 remains stable. When the fruits and vegetables are close to the crushing structure, the driving member 100 drives the rolling plate 300 to move. After the opposite sides of the fruits and vegetables are clamped by the rolling plate 300 and the pressure plate 430, the first power device 410 continues to push the pressure plate 430 toward the rolling plate 300 to flatten the fruits and vegetables, extract the juice and drain the juice into the juice storage box 420 through the filter holes. At the same time, the driving member 100 continues to drive the rolling plate 300 to move to crush the material 500 to be squeezed in the circumferential direction, so that the juice is more comprehensive and the juice yield of the juicer is improved. After the juice extraction is completed, the first power device 410 drives the pressure plate 430 to move away from the rolling plate 300. At the same time, the driving member 100 stops driving the rolling plate 300 to move, and then removes the squeezed fruit and vegetable residues on the pressure plate 430 to facilitate the next juice extraction process.
[0034] In the embodiment of the present utility model, please refer to Figures 1 to 3The rolling structure is applied to a juicer, the juicer includes a frame 400, and the rolling structure includes:
[0035] A driving member 100, wherein the driving member 100 is provided with an output shaft 110, and the driving member 100 is arranged on the frame 400;
[0036] The transmission member 200 includes a connecting shaft 210, the connecting shaft 210 and the output shaft 110 are mutually nested, one of the connecting shaft 210 and the output shaft 110 includes a slot 212 extending in the axial direction, and the other includes a fixing portion, which is circumferentially fixed to the slot 212; and
[0037] The rolling plate 300 is relatively fixedly mounted on the frame 400 in the axial direction. The transmission member 200 is drivingly connected to the rolling plate 300. The rolling plate 300 is used to crush the material 500 to be squeezed.
[0038] In the process of assembling the rolling structure of the utility model, the driving member 100 is first fixed to the frame 400, and then the connecting shaft 210 of the transmission member 200 and the output shaft 110 are nested and assembled in an axially aligned posture, and the clamping part and the clamping groove 212 are clamped to ensure that the output shaft 110 and the connecting shaft 210 can rotate synchronously in the circumferential direction, so that the power is transmitted to the rolling plate 300 through the transmission member 200, and the rolling plate 300 is driven to squeeze the juice material 500 to be squeezed, wherein the clamping groove 212 is on the connecting shaft 210 or the output shaft 110 is axially extended, and after the slot 212 is engaged with the fixing portion, there is a gap at both ends of the axial direction relative to the fixing portion. In this way, after the slot 212 is engaged with the fixing portion in the circumferential direction to complete the installation of the transmission member 200, there is an axial gap between the transmission member 200 and the output shaft 110. The gap can provide an axial buffer space for the rolling plate 300 to be installed at a predetermined position, thereby avoiding the installation position of the rolling plate 300 being interfered with by the transmission member 200 due to process errors and being unable to be installed at the predetermined position, thereby improving the assembly convenience of the rolling plate 300.
[0039] It should be noted that the output shaft 110 can be directly extended from the body of the driver 100, or a transmission structure can be set at the port of the driver 100 to change the relative posture of the output shaft 110 and the body of the driver 100, so as to ensure that the output shaft 110 and the connecting shaft 210 can be mutually nested in the axial direction, and the body of the driver 100 can be flexibly placed, thereby reducing the volume of the juice extractor. In addition, the axial directions of the output shaft 110, the connecting shaft 210, the rolling disc, etc. described in this solution are all consistent with the direction in which the rolling disc 300 is installed on the frame 400, that is, the installation direction of the rolling disc 300 is parallel to the extension direction of the output shaft 110 and the connecting shaft 210, and the buffer gap between the output shaft 110 and the connecting shaft 210 in the axial direction can align the installation position of the rolling disc 300 in its installation direction, and during the use of the juice extractor, the gap between the clamping groove 212 and the clamping portion in the axial direction can also provide a buffer gap for the rolling disc 300 to prevent the rolling disc 300 from being damaged by hard collision.
[0040] Without loss of generality, the rolling plate 300 can roll the material to be squeezed 500 by oscillating motion, or the rolling plate 300 can also roll the material to be squeezed 500 by rotating, wherein the rolling plate 300 is not flat against the material to be squeezed, so that the rotation process can continuously squeeze the material to be squeezed 500, or the rolling plate 300 rolls the material to be squeezed 500 by oscillating and rotating, wherein the above motion modes all move around the axial center of the rolling plate 300. Specifically, the driving member 100 can be configured as a motor, a cylinder or an oil cylinder. For how the rolling plate 300 performs oscillating motion, in one embodiment, please refer to Figure 6 The rolling plate 300 has a rolling surface that abuts against the material 500 to be squeezed, and the rolling plate 300 is relatively fixedly installed on the frame 400 in the circumferential direction. The rolling plate 300 is arranged above the pressure plate 430 at intervals. The rolling plate 300 has a first axis, and the rolling surface is distributed circumferentially around the first axis. The rolling surface protrudes in the direction close to the pressure plate 430 and intersects with the reference point at the intersection of the first axis. The distance between the reference point and the pressure plate 430 is adjustable; at the same time, the driving member 100 drives the rolling plate 300 to deflect around the second axis, and the second axis and the first axis are set at an acute angle, so that the first axis can revolve around the second axis, and the rolling surface can contact the material 500 to be squeezed in sequence around the second axis in the circumferential direction. Among them, the second axis extends in a vertical direction and is parallel to the assembly direction of the rolling plate 300. In this way, the rolling plate 300 performs a pendulum motion, constantly changing the position where the rolling plate 300 abuts against the fruits and vegetables, so as to avoid excessive damage to the skin of the fruits and vegetables by the rolling plate 300, thereby reducing the content of poor-tasting ingredients in the juice and improving the taste of the juice.
[0041] In one embodiment, please refer to Figures 1 to 3, the card slot 212 is provided on the connecting shaft 210, the clamping part is provided on the output shaft 110, the end of the connecting shaft 210 is provided with a slot 211, the output shaft 110 is inserted in the slot 211, the card slot 212 is provided on the side slot wall of the slot 211, and is provided through the slot 211. It can be understood that in the process of assembling the rolling structure, the end of the output shaft 110 is inserted in the slot 211, and the clamping part needs to be aligned with the opening of the card slot 212 in the axial direction, thereby providing a positioning reference for the installation of the transmission member 200, and realizing the clamping of the output shaft 110 and the connecting shaft 210, wherein the clamping part can move axially on the card slot 212, thereby adjusting the position of the transmission member 200 in the axial direction, and then adjusting the position of the rolling plate 300, and improving the installation convenience of the rolling plate 300. Specifically, the clamping portion can be a clamping protrusion protruding from the outer side of the connecting shaft 210, or can be configured as a pin; in addition, the clamping groove 212 can also penetrate the groove wall of the slot 211 in the radial direction, and form a notch in the groove wall at the notch of the slot 211, or the clamping groove 212 is recessed from the side groove wall of the slot 211 and axially penetrates the notch of the slot 211. Of course, in other embodiments, a groove can also be provided at the end of the output shaft 110, and the connecting shaft 210 is inserted into the groove of the output shaft 110, or the clamping portion is provided on the connecting shaft 210, and the clamping groove 212 is provided on the output shaft 110.
[0042] Further, in this embodiment, please refer to Figures 1 to 3 , the end of the output shaft 110 is provided with a plug hole 111 along its radial direction, and the clamping part is configured as a plug rod, and the plug rod (not shown) is inserted into the plug hole 111 and clamped in the clamping slot 212. It can be understood that in the process of inserting the output shaft 110 into the slot 211, it is not necessary to adjust the relative posture of the output shaft 110 and the connecting shaft 210, thereby improving the connection convenience of the transmission member 200 and the driving member 100. After the output shaft 110 is inserted into the slot 211, the output shaft 110 or the connecting shaft 210 is rotated in the circumferential direction so that the plug hole 111 on the output shaft 110 is opposite to the clamping slot 212, and then the plug rod is inserted into the plug hole 111, so that the connecting shaft 210 and the output shaft 110 are clamped in the circumferential upper limit position, ensuring that the two can rotate synchronously, thereby driving the rolling disc 300 to squeeze the juice material 500 to be squeezed. Of course, in other embodiments, the slot 212 may not be a slot that passes through the slot 211 axially, and the fixing portion can elastically expand and contract in the radial direction of the connecting shaft 210. During the connection process, the fixing portion is first retracted into the connecting shaft 210. When the output shaft 110 is inserted to the predetermined position, the fixing portion is radially opposite to the slot 212, thereby elastically resetting to be fixed in the slot 212.
[0043] In one embodiment, please refer to Figures 1 to 3The rolling structure also includes a mounting member 220, which is rotatably sleeved on the outer circumference of the connecting shaft 210 and relatively fixed to the connecting shaft 210 in the axial direction. The mounting member 220 is used to be installed on the frame 400. It can be understood that the transmission member 200 is installed on the frame 400 through the mounting member 220, so that the transmission member 200 and the frame 400 remain stable. Specifically, the mounting member 220 is sleeved on the outer circumference of the connecting shaft 210 to limit the movement of the connecting shaft 210 relative to the frame 400 in the horizontal direction, and when the connecting shaft 210 rotates, the mounting member 220 and the connecting shaft 210 are circumferentially slidably abutted. For example, a bearing is provided between the mounting member 220 and the connecting shaft. Furthermore, the mounting member 220 can also be relatively fixed to the connecting shaft 210 in the axial direction to ensure that the transmission member 200 is axially fixed to the connecting shaft 210. It is relatively stable upward with the rolling disc 300 and the driving member 100. It should be noted that during the assembly process, the transmission member 200 is first connected to the driving member 100, and then the rolling disc 300 is installed to the predetermined position through the buffer gap between the clamping groove 212 and the clamping part, and then the rolling disc 300 is fixed relative to the frame 400 in the axial direction. Finally, the mounting member 220 is locked to the frame 400, thereby ensuring that the transmission member 200 can remain stable, thereby stably transmitting the power output by the driving member 100 to the rolling disc 300, and ensuring the effect of the rolling disc 300 squeezing the juice material 500. Of course, in other embodiments, the lower end of the transmission member 200 is fixedly connected to the rolling disc 300, and the upper end is circumferentially limited with the output shaft 110, so that the transmission member 200 can stably transmit the power output by the driving member 100 to the rolling disc 300.
[0044] Further, in this embodiment, please refer to Figures 1 to 3 The connecting shaft 210 is fixedly provided with two stop rings 213 along its axial direction, and the two stop rings 213 are slidably abutted against the axial ends of the mounting member 220. It can be understood that the stop rings 213 are radially protruding relative to the outer periphery of the connecting shaft 210, and can be kept stable at a specific position of the connecting shaft 210, so as to limit the mounting member 220 between the two stop rings 213, thereby ensuring that the transmission member 200 and the frame 400 remain stable. Specifically, the position of the stop ring 213 on the connecting shaft 210 can be adjusted to adapt to rolling structures of different specifications.
[0045] Specifically, in this embodiment, please refer to Figures 1 to 3 The outer circumference of the mounting member 220 is bent to form a mounting flange 221, which is used to be mounted on the frame 400. It should be noted that the mounting flange 221 is continuous in the circumferential direction, so that the forces acting on the mounting member 220 and the frame 400 in the circumferential direction tend to be balanced, thereby improving the stability of the mounting member 220 on the frame 400, thereby ensuring that the transmission member 200 stably transmits the power output by the driving member 100 to the rolling plate 300.
[0046] In one embodiment, please refer to Figures 1 to 3 The transmission member 200 further includes a swing arm 230, which is connected to the connecting shaft 210 at an angle and rotates synchronously with the connecting shaft 210. The swing arm 230 slides and presses against the rolling plate 300, so that the rolling plate 300 performs an eccentric motion around its axis. Without loss of generality, a guide ring is provided on the side of the rolling plate 300 facing the transmission member 200, and the guide ring abuts against the end of the swing arm 230 away from the connecting shaft 210. During the rotation of the output shaft 110, the connecting shaft 210 rotates synchronously, thereby driving the swing arm 230 to perform a circular motion around the axis of the connecting shaft 210, thereby driving the rolling plate 300 to perform an eccentric motion around the center of the guide ring, thereby extracting juice from the material 500 to be squeezed. The center of the guide ring is the axis of the rolling disc 300, so that the rolling disc 300, the connecting shaft 210 and the output shaft 110 are coaxially arranged to ensure the uniformity of the rolling disc 300 in squeezing the material 500 to be squeezed and the juice yield of the material 500 to be squeezed. Specifically, the swing arm 230 and the connecting shaft 210 can be integrally formed or detachably connected. A plug hole 111 is provided at the end of the swing arm 230, and a flat position is arranged in the plug hole 111. A flat position is provided at the end of the connecting shaft 210 away from the output shaft 110. The connecting shaft 210 is inserted into the plug hole 111 of the swing arm 230, and the flat position of the connecting shaft 210 abuts against the flat position of the plug hole 111, so that the rotation of the connecting shaft 210 can drive the swing arm 230 to rotate synchronously. In addition, the swing arm 230 extends obliquely between the rolling plate 300 and the connecting shaft 210, and the abutment between the swing arm 230 and the rolling plate 300 is arranged closer to the rolling plate 300 than the connection between the swing arm 230 and the connecting shaft 210, and the angle between the swing arm 230 and the connecting shaft 210 can be a right angle or an obtuse angle. Of course, in other embodiments, the two ends of the swing arm 230 can be fixedly connected to the connecting shaft 210 and the rolling plate 300 respectively, so that the transmission member 200 and the rolling plate 300 form a whole.
[0047] In one embodiment, please refer to Figure 4 and Figure 5The rolling plate 300 is also provided with a support channel 310 which is at an angle to the connecting shaft 210, and a limited position cavity 311 is formed in the support channel 310. The rolling structure also includes a support rod 320, and the support rod 320 is provided with a support bearing 321. The support rod 320 passes through the support channel 310, and the support bearing 321 is limitedly installed in the limited position cavity 311. The rolling plate 300 can swing around the support bearing 321, and the end of the support rod 320 is used to connect to the frame 400. It should be noted that the rolling plate 300 has a rolling surface that abuts against the material 500 to be squeezed, and the extension direction of the support channel 310 is arranged in parallel with the rolling surface, that is, the support channel 310 and the rolling surface do not have an intersecting part on the rolling plate 300 to avoid interfering with the rolling surface in squeezing the juice of the material 500 to be squeezed. At the same time, the support bearing 321 of the support rod 320 is limitedly installed in the limit cavity 311, and the rest of the support rod 320 retains a certain gap with the support channel 310. In this way, during the juicing process, the rolling plate 300 can With the support bearing 321 as the fulcrum, the rolling plate 300 performs an eccentric motion around the support bearing 321. Compared with the rolling plate 300 that rotates to crush the material 500 to be squeezed, the rolling plate 300 of this scheme does not rotate, but only eccentrically crushes different areas of the material 500 to be squeezed in the circumferential direction in turn. That is, the rolling plate 300 will not have relative rotation and dynamic friction with the material 500 to be squeezed in the circumferential direction, which can reduce the damage to the skin of the material 500 to be squeezed by rolling, thereby reducing the portion of the squeezed juice coming from the skin of the material 500 to be squeezed, so as to improve the taste of the juice.
[0048] Further, in this embodiment, please refer to Figure 4 and Figure 5 , a vibration-damping ring 313 is provided around the side wall of the support channel 310, and the vibration-damping ring 313 is used to abut against the support rod 320. It can be understood that when the rolling plate 300 performs a swaying motion to squeeze juice, the vibration-damping ring 313 on the support channel 310 abuts against the support rod 320, thereby improving the supporting and limiting effect of the support rod 320 on the rolling plate 300, so that the rolling plate 300 can better press the material 500 to be squeezed, and also prevent the rolling plate 300 from being over-pressed to damage the juicer or squeezing out too much juice with poor taste, and the vibration-damping ring 313 can prevent the support rod 320 from having a hard contact with the side wall of the support channel 310, avoid damage to the rolling plate 300, and improve the stability of the rolling plate 300 in squeezing the material 500 to be squeezed. Specifically, the vibration-damping ring 313 can be arranged near the outlet of the support channel 310, or near the limiting cavity 311, or the vibration-damping ring 313 completely covers the side wall of the support channel 310. Of course, in other embodiments, the vibration-damping ring 313 can also be sleeved on the support rod 320.
[0049] Further, in this embodiment, please refer to Figure 4 and Figure 5 , a limiting groove 312 is recessed at the opening of the support channel 310, and the vibration-damping ring 313 is adapted to be installed in the limiting groove 312, and has a convex portion that is larger than the notch of the limiting groove 312. It can be understood that since the vibration-damping ring 313 has a convex portion that is larger than the surface of the side wall of the support channel 310, the support rod 320 is preferentially pressed against the vibration-damping ring 313, thereby ensuring the vibration-damping effect between the support rod 320 and the rolling plate 300. In this way, the vibration-damping ring 313 is fixed in the limiting groove 312 to prevent the vibration-damping ring 313 from being dislocated, thereby ensuring the stability of the vibration-damping contact between the support rod 320 and the rolling plate 300. Of course, in other embodiments, the vibration-damping ring 313 can also be bonded to the side wall of the support channel 310, and the side wall of the support channel 310 is not provided with an annular groove.
