Description

TECHNICAL FIELD

[0001] The present application relates to a device for controlling the opening and closing of a transmission pipeline, in particular to a transmission pipeline blocking assembly. The present application also relates to a fat processing device having the above-mentioned transmission pipeline blocking assembly. BACKGROUND

[0002] In some application scenarios, it is necessary to transmit substances (such as liquid substances, gaseous substances) through a pipeline, and it is necessary to control the opening and closing of the pipeline from the outside without contacting the internal substances, so as to avoid contacting the internal transmission substances.

[0003] For example, in the process of fat processing, fat tissue needs to be washed, enzymatically digested and separated, the purpose of which is to extract adipose-derived regenerative cell groups (ADRCs) in the fat tissue for research in the field of regenerative medicine. Since the transmission of cleaning liquid, waste liquid and intermediate products is involved in the process of fat processing, the transmission of these substances needs to be avoided from the outside, so the opening and closing control of the transmission pipeline of these substances is usually achieved by repeatedly squeezing the transmission pipeline. In this process, the opening and closing accuracy of the opening and closing device, the response speed of the opening and closing control, and the wear of the transmission pipeline and the opening and closing device caused by repeatedly squeezing the transmission pipeline need to be considered.

[0004] At the same time, since there are many substances to be transmitted in the above-mentioned fat processing process, a complex pipeline transmission structure needs to be arranged for an integrated device, and a cleverly designed pipeline opening and closing control device can effectively reduce the complexity of the pipeline transmission structure. SUMMARY

[0005] In view of the above problems, the present application discloses a transmission pipeline blocking assembly, which can improve the accuracy of pipeline opening and closing, control the response speed of the opening and closing pipeline, and reduce the wear of the transmission pipeline and the opening and closing device caused by repeatedly squeezing the transmission pipeline during the pipeline opening and closing process, thereby ensuring the safety during the pipeline opening and closing process. Moreover, it can respond to the control of multiple transmission pipelines, effectively reducing the complexity of the pipeline transmission structure.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0007] The present application provides a transmission pipeline blocking assembly, which comprises a top rod and a rotating cam, wherein the top rod can move along a blocking direction, the top rod has a sliding end and a blocking end arranged oppositely along the blocking direction, and the top rod further comprises a roller arranged at the sliding end and a blocking contact arranged at the blocking end.

[0008] The rotating cam is capable of rotating around a rotating shaft, and a working surface capable of sliding contact with the roller is formed in the circumferential direction of the rotating cam to push the ejector rod to move in the blocking direction by the roller. The working surface arranged in the circumferential direction of the rotating cam includes: a locking contact area, which is a cylindrical surface, the axis of the cylindrical surface coincides with the rotating shaft; an opening and closing contact area, which is a plane parallel to the rotating shaft; and a transition contact area, which is a plane parallel to the rotating shaft and is connected between the locking contact area and the opening and closing contact area. When the roller is located at the connection position of the opening and closing contact area and the transition contact area, the roller is located at the position farthest from the rotating shaft on the opening and closing contact area, and the roller is located at the position closest to the rotating shaft on the transition contact area.

[0009] The rotating rotating cam can realize the turn-by-turn sliding contact of the roller with the locking contact area, the opening and closing contact area and the transition contact area of the working surface. Since the distances between the three areas and the rotating shaft are different, the sliding of the roller on different areas can push the ejector rod to reciprocate in the blocking direction, and the blocking contact connected to the blocking end of the ejector rod also reciprocates in the blocking direction to realize the blocking and opening of the transmission pipeline. By controlling the rotating speed and rotating angle of the rotating cam, the accuracy and response speed of the pipeline on-off can be improved. The setting of the transition contact area can slow down the impact of the blocking contact on the transmission pipeline during the blocking and opening of the transmission pipeline, reduce the wear of the transmission pipeline and the on-off device caused by repeated extrusion of the transmission pipeline during the pipeline on-off process, and ensure the safety during the pipeline on-off process. One rotating cam can also drive multiple ejector rods to cooperatively control multiple pipelines, effectively reducing the complexity of the pipeline transmission structure.

[0010] In one illustrative embodiment of the transmission pipeline blocking assembly, along the circumferential direction of the rotating cam, the working surface can be divided into four contact areas, which are: one opening and closing contact area, one locking contact area and two transition contact areas. This design can make the roller slide in the locking contact area for a longer time and in the opening and closing contact area for a shorter time.

[0011] In one illustrative embodiment of the transmission pipeline blocking assembly, along the circumferential direction of the rotating cam, the working surface is divided into eight contact areas, which are: two opening and closing contact areas, two locking contact areas and four transition contact areas. This design allows the roller to quickly alternate sliding on the opening and closing contact area and the locking contact area.

[0012] In an exemplary embodiment of the transmission pipeline blocking assembly, the transmission pipeline blocking assembly further comprises a fixing frame and a guide device, wherein the guide device is fixedly arranged on the fixing frame, and the top rod is slidably connected to the guide device. This design allows the top rod to reciprocate along the blocking direction during the operation of the transmission pipeline blocking assembly, thereby achieving the blocking and opening of the transmission pipeline by the blocking contact.

[0013] In an exemplary embodiment of the transmission pipeline blocking assembly, the guide device is a track structure, which allows the top rod to reciprocate along the blocking direction by sliding up and down the track.

[0014] In an exemplary embodiment of the transmission pipeline blocking assembly, the fixing frame comprises a fixing plate, the guide device is arranged on the fixing plate, the sliding direction of the top rod is perpendicular to the fixing plate, and the fixing plate is provided with a limiting hole for the top rod. This design prevents the top rod from tilting during reciprocation along the blocking direction, thereby ensuring the stability of the top rod during reciprocation.

[0015] In an exemplary embodiment of the transmission pipeline blocking assembly, the transmission pipeline blocking assembly further comprises a return spring, the return spring is sleeved on the top rod, one end of the return spring is capable of abutting against the fixing plate, and the other end of the return spring is capable of abutting against the sliding end of the top rod, thereby providing an elastic force to ensure that the roller arranged on the sliding end is always in sliding contact with the rotating cam. This design ensures that the elastic force provided by the return spring can always keep the roller in sliding contact with the rotating cam during the reciprocation of the top rod, thereby preventing the roller from being separated from the rotating cam during frequent reciprocation of the top rod.

[0016] In an exemplary embodiment of the transmission pipeline blocking assembly, the blocking contact of the top rod comprises a blocking cylinder, a blocking latch, and a buffer spring, wherein the blocking cylinder is formed with a sliding cavity along the extension direction of the top rod, and the sliding cavity is open towards the blocking direction; the blocking latch is arranged in the sliding cavity and is capable of extending out of the opening; one end of the buffer spring abuts against the blocking latch, and the other end of the buffer spring abuts against the bottom wall of the blocking cylinder. This design allows the buffer spring to reduce the impact of the blocking contact on the transmission pipeline during the blocking and opening of the pipeline by the blocking contact, thereby reducing the wear of the transmission pipeline and the on-off device caused by repeated extrusion of the blocking contact on the transmission pipeline.

[0017] In an exemplary embodiment of the transmission pipeline blocking assembly, along the axial direction of the rotating cam, the rotating cam is arranged with a plurality of working curves, and the transmission pipeline blocking assembly further comprises a top rod corresponding to each working curve. This design allows one rotating cam to drive multiple top rods to cooperatively control multiple pipelines, thereby effectively reducing the complexity of the pipeline transmission structure.

[0018] In one illustrative embodiment of the transmission pipeline blocking assembly, the work curves do not coincide in the radial section of the rotating cam. This design can achieve the control of different blocking or opening of different transmission pipelines at the same time by the rotation of one rotating cam, and simplify the complex design of the control pipeline transmission.

[0019] In one illustrative embodiment of the transmission pipeline blocking assembly, the transmission pipeline blocking assembly further comprises a positioning disc and a first photoelectric sensor. The positioning disc is arranged on the rotating shaft and can rotate with the rotating cam. A plurality of first positioning notches are arranged on the edge of the positioning disc in the circumferential direction. The first photoelectric sensor is arranged at a first detection position on the edge of the positioning disc and can output a corresponding feedback signal when each first positioning notch reaches the first detection position. This design can enable the operator to obtain the blocking or opening state of one transmission pipeline at this time according to the feedback signal of the photoelectric sensor during the working process of the transmission pipeline blocking assembly.

[0020] In one illustrative embodiment of the transmission pipeline blocking assembly, when the first positioning notch reaches the first detection position, the roller of one top rod is located at the position on the opening and closing contact area corresponding to the roller and the shortest distance from the rotating shaft, or the roller of one top rod is located at the connecting position of the opening and closing contact area and the transition contact area corresponding to the roller. This design enables the operator to determine that one transmission pipeline is in an opening state or one transmission pipeline is in a state of being about to open or being about to block at this time when the first positioning notch reaches the first detection position.

[0021] In one illustrative embodiment of the transmission pipeline blocking assembly, a second positioning notch is further arranged on the edge of the positioning disc in the circumferential direction. The transmission pipeline blocking assembly further comprises a second photoelectric sensor. The second photoelectric sensor is arranged at a second detection position on the edge of the positioning disc and can output a corresponding feedback signal when the second positioning notch reaches the second detection position. This design can enable the operator to obtain the blocking or opening state of a plurality of transmission pipelines at this time according to the feedback signal of the photoelectric sensor during the working process of the transmission pipeline blocking assembly.

[0022] In one illustrative embodiment of the transmission pipeline blocking assembly, when the second positioning notch reaches the second detection position, the rollers of the top rods are located at the opening and closing contact areas corresponding to the rollers at the same time, and are located at the positions on the opening and closing contact areas corresponding to the rollers and the shortest distance from the rotating shaft. This design enables the operator to determine that a plurality of transmission pipelines are in an opening state at the same time when the second positioning notch reaches the second detection position.

[0023] The application also provides a fat processing device, which comprises a transmission pipeline and the transmission pipeline blocking assembly.

[0066] In order to have a clearer understanding of the technical features, objects and effects of the present application, the specific embodiments of the present application will be described with reference to the accompanying drawings, in which the same reference numerals represent the same or similar components having the same function.

[0067] In the present document, "illustrative" means "serving as an example, instance, or illustration" and should not necessarily be construed as preferred or advantageous over other technologies.

[0068] The transmission pipe blocking assembly can be used to control the opening and closing of the liquid pipe, especially for the liquid pipe which needs to avoid contact with the internal substance. The transmission pipe blocking assembly can extrude the liquid pipe from the outside of the liquid pipe to achieve the opening and closing control of the liquid pipe. Of course, those skilled in the art can understand that the transmission pipe is not limited to the liquid pipe, for example, it can also be a gas pipe and the like.

[0069] Figure 1 An exploded structural schematic diagram illustrating an illustrative embodiment of the transmission pipe blocking assembly. Figure 2 is Figure 1 A combined state schematic diagram of the transmission pipe blocking assembly is shown. As shown in Figure 1 and Figure 2 The transmission pipe blocking assembly includes a top rod 10 and a rotating cam 22, wherein the top rod 10 can move along the blocking direction (up and down direction shown by the arrow in the middle) Figure 2 , the top rod 10 has a relatively arranged sliding end 11 and a blocking end 13 along the blocking direction, and the top rod 10 includes a roller 12 arranged at the sliding end 11 and a blocking contact 14 arranged at the blocking end 13, wherein the blocking contact 14 is a structure that can be used to block the transmission of the pipe.

[0070] As shown in Figure 1 and Figure 2As shown, the transmission pipeline blocking assembly further comprises a rotary cam 22, which is capable of rotating around a rotation axis 40 shown by a dashed line in the figure, and the rotary cam 22 can be rotated by a driving motor, for example. A working surface 24 capable of sliding contact with the roller 12 of the ejector rod 10 is formed in the circumferential direction of the rotary cam 22. In actual operation, when the rotary cam 22 rotates around the rotation axis 40, the roller 12 is in sliding contact with the working surface 24 of the rotary cam 22, and as the working surface 24 of the rotary cam 22 changes, the roller 12 and the ejector rod 10 are pushed to move in the above-mentioned blocking direction, and during the movement, the blocking contact 14 of the ejector rod 10 opens or blocks a transmission pipeline 60 (see Figures 3 to 7 ).

[0071] As shown in Figure 1 , the working surface 24 in sliding contact with the roller 12 in the circumferential direction of the rotary cam 22 includes a locking contact area 242, an opening and closing contact area 244, and a transition contact area 246, which can be simultaneously referred to Figures 3 to 7 , wherein the locking contact area 242 is a cylindrical surface, and the axis of the cylindrical surface coincides with the rotation axis 40. The cylindrical surface can be understood as a curved surface generated by a straight line (generatrix) parallel to a circle (directrix). The opening and closing contact area 244 is a plane parallel to the rotation axis 40. The transition contact area 246 is a plane parallel to the rotation axis 40, and the transition contact area 246 is connected between the locking contact area 242 and the opening and closing contact area 244. The above-mentioned three areas are connected to form the working surface 24 of the rotary cam.

[0072] Wherein, when the roller 12 is located at the connecting position of the opening and closing contact area 244 and the transition contact area 246, referring to Figure 4 , the roller 12 is located at the position on the opening and closing contact area 244 farthest away from the rotation axis 40, and the roller 12 is located at the position on the transition contact area 246 closest to the rotation axis 40. That is, the distance between the roller 12 at each position on the opening and closing contact area 244 and the rotation axis 40 is not the same, and when the roller is located at the connecting position of the opening and closing contact area 244 and the transition contact area 246, the distance between the roller and the rotation axis 40 is the position farthest away from the rotation axis 40. Similarly, the distance between the roller 12 at each position on the transition contact area 246 and the rotation axis 40 is not the same, and when the roller is located at the connecting position of the opening and closing contact area 244 and the transition contact area 246, the distance between the roller and the rotation axis 40 is the position closest to the rotation axis 40.

[0073] Figure 2 is Figure 1 the combined state diagram of the transmission pipeline blocking assembly as shown. As Figure 2As shown, in actual working process, the roller 12 slides in contact with the working surface 24 of the rotary cam 22, when the rotary cam 22 rotates around a rotating shaft 40, the roller 12 slides on the working surface 24 of the rotary cam 22, since the working surface 24 is provided with three different regions, and the three regions are different from the distance of the rotating shaft 40, so that the top rod 10 reciprocates along the blocking direction, so as to realize the blocking and opening process of the blocking contact 14 connected to the blocking end 13 of the top rod 10 to the transmission pipeline. The specific working form of the top rod 10 and the rotary cam 22 of the transmission pipeline blocking assembly to control the blocking and opening of the pipeline will be described in detail below.

[0074] Figure 3 A working schematic diagram is used to illustrate the cooperation of the top rod and the rotary cam of the transmission pipeline blocking assembly. As shown in Figure 3 , at this time, the roller 12 of the top rod 10 is located on the opening and closing contact region 244 of the working surface 24 of the rotary cam 22, and the distance from the roller 12 to the rotating shaft 40 is L1, which is the shortest position between the roller 12 and the rotating shaft 40 in the working surface 24, and can be called the opening position. At this time, the top rod 10 is just in contact or not in contact with the transmission pipeline 60, and the transmission pipeline 60 is in an open state, and the internal liquid can be transmitted (as shown by the dashed arrow in the transmission pipeline 60). When the rotary cam 22 rotates counterclockwise as shown in Figure 3 , the roller 12 slides along the working surface 24 of the rotary cam 22 to the position shown in Figure 4 .

[0075] Figure 4 Another working schematic diagram is used to illustrate the cooperation of the top rod and the rotary cam of the transmission pipeline blocking assembly. As shown in Figure 3 and Figure 4 , as the rotary cam 22 rotates counterclockwise, the roller 12 slides from the opening position of the opening and closing contact region 244 of the rotary cam 22 to the connecting position of the opening and closing contact region 244 and the transition contact region 246, at this time, the distance from the roller 12 to the rotating shaft 40 is L2, as shown in Figure 4 , it can be known that the length of L2 is longer than the length of L1, that is, as the rotary cam 22 rotates from the state shown in Figure 3 to the state shown in Figure 4 , the distance from the roller 12 to the rotating shaft 40 gradually increases from L1 to L2, then at this time, the top rod 10 rises in the blocking direction, then the blocking contact 14 connected to the blocking end 13 of the top rod 10 will gradually compress the transmission pipeline 60. At this time, the flow area of the transmission pipeline 60 compressed by the blocking contact 14 is reduced.

[0076] When the rotary cam 22 rotates counterclockwise as shown in Figure 4When rotated counterclockwise as shown, roller 12 continues to slide along the working surface 24 of the rotating cam 22. Figure 5 The working status shown. Figure 5 This is another schematic diagram illustrating the interaction between the push rod and the rotating cam of the transmission pipeline blocking assembly. For example... Figure 5 As shown, at this time, the roller 12 of the push rod 10 is located in the middle of the transition contact area 246 of the working surface 24 of the rotary cam 22. At this time, the distance from the roller 12 to the rotating shaft 40 is L3. As can be seen from the figure, the length of L3 is longer than L2, that is, as the rotary cam 22 moves from... Figure 4 The state shown rotates to Figure 5 When the state shown is such that the distance between the roller 12 and the rotating shaft 40 increases from the length of L2 to L3, the push rod 10 continues to rise in the blocking direction, and the blocking contact 14 connected to the blocking end 13 of the push rod 10 continues to rise, thereby continuing to compress the transmission pipeline 60. At this time, the flow area of ​​the transmission pipeline 60 at the compression point of the blocking contact 14 continues to decrease.

[0077] Combination Figure 4 and Figure 5 It can be observed that regardless of whether roller 12 is in the opening / closing contact area 244 or the transition contact area 246, the distance between roller 12 and the rotating shaft 40 continuously increases as the rotation angle of the rotating cam 22 changes. This drives the push rod 10 to continue rising in the blocking direction, thereby compressing the transmission pipe 60. It can also be observed that the rate of increase in distance between roller 12 and the rotating shaft 40 differs with the rotation angle of the rotating cam 22. The rate of increase in distance for roller 12 in the transition contact area 246 is significantly slower than that in the opening / closing contact area 244. In other words, during the contact between roller 12 and both the transition contact area 246 and the opening / closing contact area 244, the compression speed of the transmission pipe 60 by the blocking contact 14 decreases.

[0078] Combination Figure 4 and Figure 5 To explain the above situation, if the working surface 24 of the rotary cam 22 does not have a transition contact area 246, that is, as the rotary cam 22 rotates counterclockwise, the roller 12... Figure 4 The position shown will continue to slide along the extended surface A1 of the opening and closing contact area 244 (see also the reference). Figure 3 Then, the distance between roller 12 and rotating shaft 40 continues to increase. When roller 12 slides to the intersection of M3 (the extension of L3) and A1, the distance between roller 12 and rotating shaft 40 should be L3 + M3, that is, the height to which push rod 10 rises along the blocking direction should be higher than L3 + M3. Figure 5 The rising height of the top rod 10 shown.

[0079] Since the increase in distance from L2 to L3+M3 is greater than the increase in distance from L2 to L3, therefore compared to Figure 5 The rising speed of the push rod 10 when the roller 12 slides along the transition contact area is faster if the roller 12 continues to slide along the extended surface A1 of the opening and closing contact area 244. Therefore, the purpose of setting the transition contact area 246 is to block the transmission pipeline while reducing the impact of the blocking contact 14 on the transmission pipeline 60.

[0080] When rotating cam 22 is Figure 5 If the counterclockwise rotation continues as shown, the roller 12 will continue to slide along the working surface 24 of the rotating cam 22. Figure 6 The working status shown. Figure 6 Another schematic diagram illustrating the interaction between the push rod and the rotating cam of the transmission pipeline blocking assembly. (For example...) Figure 6 As shown, at this time, roller 12 is located at the connection position between the transition contact area 246 and the locking contact area 242 of the working surface 24 of the rotating cam 22, and the distance from roller 12 to the rotating shaft 40 is L4. As can be seen from the figure, the length of L4 is greater than the length of L3, that is, as the rotating cam 22 moves from... Figure 5 The state shown rotates to Figure 6 In the state shown, the distance between roller 12 and rotating shaft 40 increases from length L3 to L4. At this time, push rod 10 continues to rise in the blocking direction, and the blocking contact 14 connected to the blocking end 13 of push rod 10 continues to rise, thereby blocking transmission pipeline 60. At this point, transmission pipeline 60 stops conveying liquid. Figure 6 There is no liquid flow on the right side of the blocking contact 14 shown.

[0081] When rotating cam 22 is Figure 6 If the counterclockwise rotation continues as shown, the roller 12 will continue to slide along the working surface 24 of the rotating cam 22. Figure 7 The working status shown. Figure 7 This is another schematic diagram illustrating the interaction between the push rod and the rotating cam in the transmission pipeline blocking assembly. (See attached diagram.) Figure 7 As shown, at this time, the roller 12 is located on the locking contact area 242 of the working surface 24 of the rotary cam 22, and the distance from the roller 12 to the rotating shaft 40 is L5. As can be seen from the figure, the length of L5 is equal to the length of L4. When the roller 12 is located on the locking contact area 242, its distance from the rotating shaft 40 is equal everywhere. At this time, the distance between the roller 12 and the rotating shaft 40 is maintained. That is, as the roller 12 continues to slide on the locking contact area 242 of the rotary cam 22, the push rod 10 no longer rises in the blocking direction. At this time, the blocking contact 14 connected to the blocking end 13 of the push rod 10 remains in the state of blocking the transmission pipeline 60, and the liquid in the transmission pipeline 60 is continuously blocked.

[0082] Therefore, the purpose of setting the locking contact area 242 is to maintain the plunger 10 from rising further when the plunger 10 has risen to a certain height along the blocking direction, the transmission pipeline 60 has been blocked by the blocking contact 14, and the locking contact area 242 is set, the distance between the roller 12 and the rotating shaft 40 is equal everywhere when the roller 12 is located in the locking contact area 242, which can ensure that the plunger 10 does not continue to rise, and ensure that the blocking contact 14 and the transmission pipeline 60 are not damaged while the transmission pipeline 60 is safely blocked.

[0083] According to the above description of the working process of the plunger 10 and the rotating cam 22, in the actual fat pretreatment process, the operator can control the rotating cam 22 to continuously rotate around a rotating shaft 40, so that the roller 12 of the plunger 10 can continuously slide relative to the rotating cam 22, and when the roller 12 continuously slides through the opening and closing contact area 244, the transition contact area 246 and the locking contact area 242 in turn, the plunger 10 continuously rises along the blocking direction, thereby realizing the process of the transmission pipeline of the fat pretreatment device from opening to blocking.

[0084] In the embodiment shown in the figure, when the rotating cam 22 continues to rotate counterclockwise, the roller 12 slides through the symmetrically designed locking contact area 242, the transition contact area 246 and the opening and closing contact area 244 in turn, and at this time the plunger 10 continuously descends along the blocking direction, thereby realizing the process of the transmission pipeline from blocking to opening, and the operator can realize the control switching of the transmission pipeline blocking and opening by controlling the rotating cam 22 to continuously rotate around a rotating shaft 40, so that the control of the pipeline liquid transportation in the fat pretreatment process becomes more efficient and accurate.

[0085] Of course, in other embodiments, the rotating cam 22 can also be controlled to rotate reversely, so that the roller 12 slides through the locking contact area 242, the transition contact area 246 and the opening and closing contact area 244 in turn, and at this time the plunger 10 continuously descends along the blocking direction, thereby realizing the process of the transmission pipeline from blocking to opening, that is, the operator can also realize the control switching of the transmission pipeline blocking and opening by controlling the rotating cam 22 to rotate forward or reversely around a rotating shaft 40.

[0086] In the above structure design, the method of using the working surface 24 of the rotating cam 22 to drive the plunger 10 to open and close the transmission pipeline can accurately control the position between the plunger 10 and the transmission pipeline each time the plunger 10 is closed or opened by controlling the rotation angle of the rotating cam 22, and there will be no phenomenon of excessive extrusion or insufficient extrusion force. By controlling the rotating speed of the rotating cam 22, the response time of opening or closing the pipeline can be adjusted, especially when fast response is required to switch the pipeline state, the rotating speed of the rotating cam 22 can be controlled to quickly drive the plunger 10 to the response position.

[0087] Moreover, the setting of the transition contact area 246 makes the lifting speed of the ejector rod 10 slow down when it is lifted in the blocking direction, reducing the impact on the transmission pipeline. Especially after the transmission pipeline is pressed to a certain extent, the impact of the ejector rod 10 on the transmission pipeline 60 is reduced, which has a very significant protective effect on both the transmission pipeline 60 and the blocking contact 14 of the ejector rod 10.

[0088] In addition, the above structural matching relationship can realize the possibility of driving multiple ejector rods 10 by one rotating cam 22 to cooperatively control the on-off of multiple pipelines, which will be described in detail later.

[0089] In actual products, the number of three working surfaces 24 of the rotating cam 22, i.e., the locking contact area 242, the opening-closing contact area 244, and the transition contact area 246 arranged along the circumference of the rotating cam 22, can be set according to actual needs for different use scenarios.

[0090] In one of the illustrative embodiments, along the circumference of the rotating cam 22, the working surface 24 can be divided into four contact areas, which are one opening-closing contact area 244, one locking contact area 242, and two transition contact areas 246 (for reference to the setting mode of the working surface of the rotating cam in Figures 1 to 7 This setting mode makes the roller 12 slide in contact with the locking contact area 242 for a longer time and in contact with the opening-closing contact area 244 for a shorter time.

[0091] In another illustrative embodiment, as shown in Figure 8 along the circumference of the rotating cam 22, the working surface 24 can also be divided into eight contact areas, which are two opening-closing contact areas 244, two locking contact areas, and four transition contact areas 246. This setting mode makes the roller 12 able to quickly alternate sliding on the opening-closing contact area 244 and the locking contact area 242.

[0092] In order to make the ejector rod 10 do reciprocating motion in the radial direction, the transmission pipeline blocking assembly is also provided with a fixed frame 30 and a guide device 32, which can be referred to in Figures 3 to 7 The guide device 32 is fixedly arranged on the fixed frame 30, and the ejector rod 10 is slidably connected to the guide device 32. In the actual working process, since the ejector rod 10 is slidably connected to the guide device 32, the ejector rod 10 is in a state of being able to slide relative to the fixed frame 30. Therefore, when the roller 12 continuously slides in contact with the working surface 24 of the rotating cam 22, the ejector rod 10 can do reciprocating motion in the blocking direction without being constrained by the fixed frame 30, thereby ensuring the switching of the transmission pipeline between the blocking and opening states.

[0093] The guide device 32 can be configured as a track structure, allowing it to slide on the track structure. Of course, those skilled in the art will understand that, depending on actual needs, the guide device 32 can also take other forms. Any guide device 32 with a structural design that can ensure that the push rod 10 slidably connected to the guide device 32 can slide along the blocking direction and perform reciprocating motion is within the protection scope of this application. For example, the guide device 32 can also have a sliding rod in its middle part, and the part of the push rod 10 that slides in contact with the guide device 32 can be configured as a hollow structure, so that the hollow structure of the push rod 10 is connected to the sliding rod of the guide device 32 to realize the sliding of the push rod 10 in the blocking direction.

[0094] like Figures 1 to 7 As shown, the fixing frame 30 is also provided with a fixing plate 34, the guide device 32 is provided on the fixing plate 34, and the sliding direction of the push rod 10 is perpendicular to the fixing plate 34. The fixing plate 34 is provided with a limiting hole 36 for the push rod 10 to pass through (the limiting hole is in...). Figures 1 to 7 Not shown in the drawing, please refer to the following: Figure 1 As shown in the figure, in actual operation, the guide device 32 is fixed to the fixed plate 34, which ensures the stability of the guide device 32 during operation. The push rod 10 is also restricted within the limiting hole 36 of the fixed plate 34, which can also prevent the push rod 10 from tilting when it reciprocates in the blocking direction, thus ensuring the stability of the push rod 10 when it slides.

[0095] like Figure 9 As shown, the transmission pipeline blocking assembly also includes a return spring 16, which is sleeved on the push rod 10. One end of the return spring 16 can abut against the contact fixing plate 34, and the other end can abut against the sliding end 11 of the contact push rod 10. In actual operation, since the distances between the three contact areas on the working curved surface 24 and the rotating shaft 40 are different, the roller 12 will push the push rod 10 to move in the blocking direction when it continues to slide on the working curved surface 24. A return spring 16 is sleeved on the push rod 10 between the roller 12 and the fixing plate 34. The return spring 16 can provide an elastic force to ensure that the roller 12 can continue to slide in contact with the working curved surface 24.

[0096] like Figure 9 As shown, the blocking contact 14 of the transmission pipeline blocking assembly includes a blocking cylinder 144, which has a sliding cavity formed along the extending direction of the push rod 10, and the sliding cavity opens towards the blocking side; it also includes a blocking latch 146, which is disposed in the sliding cavity and can extend out of the opening of the sliding cavity. In actual operation, the blocking latch 146 can be configured as a wedge-shaped structure, such as... Figure 9As shown, one end of the blocking transmission line 60 is composed of two beveled faces connected together. This structure can block the transmission line. Of course, those skilled in the art will understand that, depending on actual needs, the blocking latch 146 can also be designed as other structures that can block the transmission line.

[0097] The blocking contact 14 also includes a buffer spring 142. One end of the buffer spring 142 abuts against the blocking latch 146, and the other end abuts against the bottom wall of the blocking cylinder 144 of the push rod 10. The buffer spring 142 can further reduce the impact of the blocking latch 146 on the transmission pipeline during the blocking process, avoiding damage to the transmission pipeline. Moreover, its arrangement ensures that the blocking latch 146 is in a relatively movable state relative to the blocking end 13 of the push rod 10, guaranteeing the safety of the blocking latch 146 during the blocking process. The internal working mode of the blocking contact 14 during the blocking process will be described in detail below.

[0098] like Figure 9 As shown, in actual operation, when the roller 12 slides to the transition contact area 246 of the working surface 24 of the rotary cam 22, the push rod 10 rises in the blocking direction, and the blocking end 13 of the push rod 10 presses the buffer spring 142 upward. The buffer spring 142 absorbs the instantaneous force from the push rod 10 and transforms it into a smooth, gradual force that presses the blocking latch 146 upward. This reduces the impact on the transmission pipeline 60 while the blocking latch 146 compresses the transmission pipeline 60, thus achieving both blocking of the transmission pipeline 60 and ensuring safety during the blocking process.

[0099] Figure 10 This is a cross-sectional view illustrating another working mode of the blocking contact. In this mode, roller 12 is located in the locking contact area 242, and the blocking tongue 146 is in a state of completely blocking the transmission pipeline 60. As shown in the figure, the blocking end 13 of the push rod 10 presses upward against the buffer spring 142 (as indicated by the arrow marked on the push rod 10 in the figure), while the blocking tongue 146 touches the pipe fixing plate 70. The pipe fixing plate 70 applies a downward reaction force (as indicated by the arrow marked on the pipe fixing plate 70 in the figure). The upward force of the push rod 10 and the downward reaction force of the pipe fixing plate 70 act simultaneously on the buffer spring 142, compressing it. This causes the blocking tongue 146 to move downward relative to the blocking end 13 of the push rod 10, thus protecting the blocking tongue 146 from damage when blocking the transmission pipeline 60.

[0100] According to actual work needs, the transmission pipeline blocking assembly can also be arranged with multiple working curves 24 in the axial direction of the rotating cam 22, and a corresponding top rod 10 is also provided for each working curve 24, so that one rotating cam can drive multiple top rods to cooperatively control multiple pipeline blocks, effectively reducing the complexity of the pipeline transmission structure. The arrangement of the multiple working curves 24 can coincide in the radial cross section of the rotating cam 22, or can not coincide in the radial interface of the rotating cam 22.

[0101] As shown in Figure 11 , the multiple working curves do not coincide in the radial cross section of the rotating cam 22 (only three top rod transmission pipeline blocking assemblies are shown in the figure, but the specific number of top rods in the transmission pipeline blocking assembly is not limited), during the rotation of the rotating cam 22 around the rotation axis 40, the rollers 12 of the multiple top rods 10 slide on the working curves 24 of their respective rotating cams 22, and at the same time, the sliding contact areas of the rollers 12 of the multiple top rods 10 are different.

[0102] As shown in Figure 11 , from left to right, the sliding contact areas of the rollers 12 of the three top rods 10 are the locking contact area 242, the opening and closing contact area 244, and the transition contact area 246, respectively, and the corresponding transmission pipeline states are blocked, opened, and half-blocked and half-opened, respectively. When the rotating cam 22 continues to rotate around the rotation axis 40, the corresponding transmission pipeline state will change again. This arrangement of arranging multiple working curves 24 in the axial direction of a rotating cam 22 and providing a corresponding multiple top rods 10 can control the blocking and opening states of different transmission pipelines at the same time, improve the efficiency of the transmission pipeline blocking process, and simplify the complex design of the transmission pipeline.

[0103] Figure 12 A schematic diagram illustrating one application mode of the transmission pipeline blocking assembly in the pipeline transmission. As shown in Figure 12 , in addition to the three top rod 10 combination transmission pipeline blocking assembly shown in Figure 11 , it also includes two top rod 10 groups, four top rod 10 groups, and five top rod 10 groups of transmission pipeline blocking assemblies shown in Figure 12 . Of course, according to actual needs, different numbers of top rods can be provided. As shown in the figure, multiple transmission pipelines 60 are fixed on the pipeline fixing plate 70, and each transmission pipeline 60 corresponds to a blocking lock tongue 146 of a top rod 10. The dashed line shown in the figure represents the flow path of the liquid. During the pipeline transmission process, the transmission pipeline 60 through which the liquid needs to flow is in an open state, and the pipeline through which the liquid is prohibited from flowing is blocked by the blocking lock tongue 146 of the blocking contact 14 to ensure the accuracy of the liquid transportation process and avoid unnecessary liquid flow.

[0104] like Figure 11 As shown, in actual operation, in order for operators to obtain the transmission status of each pipeline in real time, the transmission pipeline blocking component is also equipped with a positioning disk 50 and a first photoelectric sensor 54. The positioning disk 50 is set on the rotating shaft 40 and can rotate with the rotating cam 22. Several first positioning notches 52 are also provided along the circumferential edge of the positioning disk 50 (see also the reference). Figure 13 (The figure only schematically shows a portion of the first positioning notches 52, and is not intended to limit the number of first positioning notches 52.) The first photoelectric sensor 54 is located at the first detection position on the edge of the positioning disk 50. When several first positioning notches 52 of the positioning disk 50 rotate to the first detection position of the positioning disk 50, the first photoelectric sensor 54 can output a corresponding feedback signal. The operator can determine the status of the transmission pipeline at this time based on the feedback signal, ensuring the accuracy of pipeline blockage.

[0105] In one illustrative embodiment, several first positioning notches 52 can each correspond to a push rod 10 in the transmission pipeline blocking assembly. When one of the first positioning notches 52 rotates to the first detection position of the positioning disk 50, the operator can determine, based on the feedback signal output by the first photoelectric sensor 54, that the roller 12 of the push rod 10 corresponding to the first positioning notch 52 is located at the position closest to the rotation shaft 40 on the opening and closing contact area 244 corresponding to the push rod 10, that is, the pipeline corresponding to the push rod 10 is in the open state.

[0106] Alternatively, several first positioning notches 52 can be set such that when one of the positioning notches 52 rotates to the first detection position of the positioning disk 50, the operator can determine, based on the feedback signal output by the first photoelectric sensor 54, that the roller 12 of the push rod 10 corresponding to the first positioning notch 52 is located at the connection position between the corresponding opening / closing contact area 244 and the transition contact area 246. At this time, the pipeline corresponding to the push rod 10 is in a state of about to open or about to be blocked.

[0107] like Figure 11 , Figure 13 As shown, a second positioning notch 56 is also provided along the circumferential direction of the edge of the positioning disk 50. Figure 13 The diagram only schematically shows a portion of the second positioning notch 56 (but is not intended to limit the number of second positioning notches 56), and also includes a second photoelectric sensor 58. The second photoelectric sensor 58 is located at a second detection position on the edge of the positioning disk 50. When the second positioning notch 56 of the positioning disk 50 rotates to the second detection position of the positioning disk 50, the second photoelectric sensor 58 can also output a corresponding feedback signal.

[0108] In an exemplary embodiment, the second positioning gap 56 is arranged for the case that the plurality of ejector rods 10 in the transmission pipeline blocking assembly are in the same state, i.e. when the second positioning gap 56 is rotated to the second detection position of the positioning disc 50, the operator can determine that the plurality of rollers 12 of the plurality of ejector rods 10 are simultaneously located at the position with the closest distance to the rotating shaft 40 on the opening and closing contact area 244 of the corresponding working cam surface 24 according to the feedback signal output by the second photoelectric sensor 58, i.e. the plurality of pipelines corresponding to the plurality of ejector rods 10 in the transmission pipeline blocking assembly are simultaneously in the open state.

[0109] As shown in Figure 13 The plurality of first positioning gaps 52 of the positioning disc 50 are smaller than the plurality of second positioning gaps 56, so as to distinguish the plurality of first positioning gaps 52 from the plurality of second positioning gaps 56. Figure 13 Only one distinguishing manner of the plurality of first positioning gaps 52 from the plurality of second positioning gaps 56 is schematically shown, and of course, those skilled in the art can understand that other distinguishing manners can be adopted according to actual needs, for example, the plurality of first positioning gaps 52 and the plurality of second positioning gaps 56 can be different in shape, and can be respectively arranged in triangular shape and square shape, etc.

[0110] The application further provides a fat treatment device, which comprises the transmission pipeline 60 and the transmission pipeline blocking assembly. The transmission pipeline 60 can be used to transport cleaning liquid, waste liquid, intermediate product, etc., and the blocking contact 14 of the ejector rod 10 can open or close the transmission pipeline 60 after the ejector rod 10 is driven by the rotating cam 22 in the transmission pipeline blocking assembly.

[0111] For the sake of simplicity of the drawings, only the parts related to the application are schematically shown in each drawing, which do not represent the actual structure of the product. In addition, for the sake of simplicity of the drawings and easy understanding, only one of the parts with the same structure or function is schematically shown, or only one of them is marked in some drawings.

[0112] It should be understood that although the present specification is described in terms of various embodiments, each embodiment does not necessarily contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined to form other embodiments that can be understood by those skilled in the art.

[0113] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the application, and are not used to limit the protection scope of the application, and any equivalent embodiments or changes made without departing from the spirit of the technical art of the application, such as combination, division or repetition of features, should be included in the protection scope of the application.
