Description

Technical Field

[0001] This utility model relates to the field of spinning machinery structure technology, and in particular to a waste removal and conveying structure. Background Technology

[0002] Currently, in the market, there are two methods for separating and removing impurities in air-suction rotor spinning machines: one is to use negative pressure suction for impurity separation, and the other is to use the centrifugal force of impurities for free separation. Among them, negative pressure suction, also known as active impurity removal, can effectively separate impurities from various raw materials containing a large amount of impurities and has a wide range of applications.

[0003] Active impurity suction spinning machines include suction tubes for conveying impurities. Currently, these suction tubes have a large inlet diameter for easy impurity recovery and a small outlet diameter to balance the negative pressure within all suction tubes, ensuring consistent negative pressure across the entire machine and thus guaranteeing good yarn consistency. However, because the diameter of the suction tube gradually decreases from the inlet to the outlet, the tube diameter that impurities pass through gradually decreases as they move within the tube. In cases of high impurity levels, this can easily cause blockages at the smaller diameter points of the suction tube, affecting the suction effect. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a suction and conveying structure that can prevent impurities from clogging the suction pipe.

[0005] To solve the above-mentioned technical problems, this utility model provides a scavenging and conveying structure, including: a scavenging pipe; an air inlet connector, the air inlet connector being snapped into the air inlet end of the scavenging pipe, the air inlet connector including an air inlet channel communicating with the scavenging pipe, the air inlet channel including a first channel and a second channel, the second channel being located between the first channel and the scavenging pipe, the diameter of the first channel gradually decreasing towards the scavenging pipe, and the diameter of the second channel gradually increasing towards the scavenging pipe; a collecting component, the collecting component including a collecting cavity, the air inlet channel communicating with the collecting cavity, the collecting component also being connected to a first connector, the first connector being used to connect with an air blowing component, the first connector communicating with the collecting cavity.

[0006] In one embodiment of the present invention, a third channel is provided between the first channel and the second channel, wherein the ends of the first channel and the second channel with the smallest diameter are respectively located at the two ends of the third channel, and the minimum diameter of the first channel, the minimum diameter of the second channel, and the diameter of the third channel are the same.

[0007] In one embodiment of this utility model, the side wall of the air inlet connector is provided with a slot, the suction pipe includes a suction channel, the side wall of the suction channel is provided with a locking block, and the locking block engages with the slot.

[0008] In one embodiment of this utility model, the side wall of the air inlet connector is further provided with a boss, the end of which abuts against the end of the suction pipe.

[0009] In one embodiment of the present invention, the collecting component includes a second connector communicating with the collecting cavity, and the air inlet connector is snapped into the second connector.

[0010] In one embodiment of the present invention, the air intake connector further includes a fourth channel and a fifth channel that are interconnected. The fourth channel is located at the end of the air intake channel, and the fifth channel is connected to the first channel. The diameter of the fifth channel gradually decreases towards the first channel, and the sidewalls of the fourth channel and the fifth channel are both in contact with the sidewall of the second connector.

[0011] In one embodiment of this utility model, the connection position of the first connector and the collection component is opposite to that of the air intake channel.

[0012] In one embodiment of this utility model, the collecting component further includes a collecting space. The collecting component has an opening, and the collecting space communicates with the collecting cavity through the opening.

[0013] In one embodiment of the present invention, a housing is further included. The housing includes a first mounting hole. An air outlet is connected to one end of the suction pipe away from the air inlet connector. The air outlet connector includes a sealing part. The diameter of the sealing part gradually decreases in the direction away from the suction pipe. The sealing part abuts against the edge of the first mounting hole.

[0014] In one embodiment of this utility model, the housing is connected to a connecting plate, the connecting plate includes a second mounting hole, the vent connector passes through the second mounting hole, the vent connector also includes a blocking part, and the connecting plate is clamped between the blocking part and the sealing part.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The present invention discloses a waste-collecting and conveying structure. By setting the diameter of the first channel in the air inlet connector to gradually decrease towards the waste-collecting pipe and the diameter of the second channel to gradually increase towards the waste-collecting pipe, a portion of the air inlet channel of the air inlet connector is formed into a funnel shape. This causes the negative pressure in the first channel to gradually increase, while the air blower can introduce airflow towards the air inlet connector. Thus, under the combined effect of negative pressure and airflow, impurities can be evenly introduced into the waste-collecting pipe, avoiding blockage of the waste-collecting pipe and the air inlet connector by impurities, and solving the adverse consequences of reduced spinning quality caused by blockage of the waste-collecting pipe.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 5 As shown, a sample collection and conveying structure of this utility model includes: a sample collection pipe 1; an air inlet connector 2, which is snapped into the air inlet end of the sample collection pipe 1, the air inlet connector 2 including an air inlet channel 23 communicating with the sample collection pipe 1, the air inlet channel 23 including a first channel 24 and a second channel 25, the second channel 25 being located between the first channel 24 and the sample collection pipe 1, the diameter of the first channel 24 gradually decreasing towards the sample collection pipe 1, and the diameter of the second channel 25 gradually increasing towards the sample collection pipe 1; and a collection component 4, which includes a collection cavity, the air inlet channel 23 communicating with the collection cavity, and the collection component 4 also being connected to a first connector 41, the first connector 41 being used to connect with an air blower, and the first connector 41 communicating with the collection cavity.

[0029] In this embodiment, a waste-collecting and conveying structure is provided. The outlet end of the waste-collecting pipe 1 is connected to an external vacuum source. After the vacuum source is activated, a negative pressure is generated at the inlet end of the waste-collecting pipe 1, causing impurities to enter the collection chamber of the collector 4. Driven by the vacuum source and the blowing device, the impurities pass through the inlet connector 2 and the waste-collecting pipe 1 in sequence before entering the air duct of the vacuum source. By setting the diameter of the first channel 24 in the inlet connector 2 to gradually decrease towards the waste-collecting pipe 1 and the diameter of the second channel 25 to gradually increase towards the waste-collecting pipe 1, part of the inlet channel 23 of the inlet connector 2 is formed into a funnel shape, thereby gradually increasing the negative pressure in the first channel 24. At the same time, the blowing device can introduce airflow towards the inlet connector 2. Thus, under the cooperation of negative pressure and airflow, impurities can enter the waste-collecting pipe 1 evenly, avoiding the blockage of the waste-collecting pipe 1 and the inlet connector 2 by impurities, and solving the adverse consequences of reduced spinning quality caused by the blockage of the waste-collecting pipe 1.

[0030] Reference Figure 2 As shown, the suction pipe 1 is used to transport impurities. The suction pipe 1 includes a suction channel, and the diameter of each position of the suction channel is equal.

[0031] Reference Figures 2 to 6As shown, the air inlet connector 2 is snapped between the suction pipe 1 and the collecting component 4. The air inlet connector 2 is snapped into the air inlet end of the suction pipe 1. The air inlet connector 2 includes an air inlet channel 23 communicating with the suction pipe 1. The air inlet channel 23 includes a first channel 24 and a second channel 25. The second channel 25 is located at the end of the air inlet channel 23 and is located between the first channel 24 and the suction pipe 1. The diameter of the first channel 24 gradually decreases towards the air outlet end of the suction pipe 1, and the diameter of the second channel 25 gradually increases towards the air outlet end of the suction pipe 1. A third channel 26 is also provided between the first channel 24 and the second channel 25. The ends with the smallest diameters of the first channel 24 and the second channel 25 are located at the two ends of the third channel 26, respectively. The minimum diameters of the first channel 24, the second channel 25, and the third channel 26 are the same, thus forming a funnel shape. Specifically, the center of the third channel 26 is 4 cm away from the air inlet end of the air inlet connector 2, and the diameter of the third channel 26 is 0.9 cm. Depending on the magnitude of the negative pressure, the diameter of the third channel 26 can also be set to 0.7 cm, 0.75 cm, 0.8 cm, 0.85 cm, etc. During operation, as the diameter of the first channel 24 gradually decreases, the negative pressure in the first channel 24 gradually increases, and the negative pressure can be concentrated in the third channel 26, while simultaneously balancing the negative pressure in the suction pipe 1 and the vacuum source duct.

[0032] The air intake connector 2 is made of plastic. The outer sidewall of the air intake connector 2 has a circumferentially arranged arc-shaped groove 22, and the sidewall of the suction channel has a circumferentially arranged arc-shaped locking block 11. Part of the air intake connector 2 can be inserted into the suction channel from the air intake end of the suction pipe 1, thereby engaging the locking block 11 with the groove 22, thus fixing the air intake connector 2 and the suction pipe 1 relatively. The sidewall of the air intake connector 2 also has a boss 21, the end of which abuts against the end of the suction pipe 1. The boss 21 improves the sealing of the engagement position between the air intake connector 2 and the suction pipe 1.

[0033] Reference Figure 7As shown, the collector 4 is used to collect impurities. The collector 4 includes a collection chamber for collecting impurities, an air inlet channel 23 communicating with the collection chamber, and a first connector 41 communicating with the collection chamber. The first connector 41 is used to connect with an air blower, which can supply air into the collection chamber. The first connector 41 is also communicating with the collection chamber. The collector 4 also includes a second connector 43 communicating with the collection chamber, and the air inlet connector 2 is engaged with the second connector 43. Specifically, the diameter of the end of the second connector 43 gradually decreases. The air intake connector 2 includes a fourth channel 27 and a fifth channel 28 that are interconnected. The fourth channel 27 is located at the end of the air intake channel 23 away from the second channel 25. The fifth channel 28 is connected to the first channel 24. The diameter of the fifth channel 28 gradually decreases towards the first channel 24. The sidewalls of the fourth channel 27 and the fifth channel 28 are both in contact with the sidewall of the second connector 43. The sidewall of the fifth channel 28 is in contact with the end sidewall of the second connector 43, thereby engaging the second connector 43 with the air intake connector 2, thereby fixing and sealing the second connector 43 and the air intake connector 2.

[0034] The connection position of the first connector 41 and the collecting element 4 is opposite to that of the air inlet channel 23, that is, the first connector 41 and the second connector 43 are opposite to each other. This allows the airflow introduced by the blowing element through the first connector 41 to enter the air inlet connector 2 through the collecting chamber. In turn, the airflow can carry impurities into the air inlet connector 2. At the same time, the negative pressure and airflow work together to allow the impurities to enter the suction pipe 1 evenly after passing through the air inlet connector 2. The diameter of each position of the suction channel is equal, thereby avoiding the blockage of the suction pipe 1 and the air inlet connector 2 by impurities, and solving the adverse consequences of reduced spinning quality caused by the blockage of the suction pipe 1.

[0035] The collecting component 4 also includes a collecting space. The collecting component 4 has an opening 42, which is located at the bottom of the collecting space. The collecting space is connected to the collecting chamber through the opening 42, so that impurities can enter the collecting chamber through the collecting space and the opening 42 under the influence of negative pressure.

[0036] Reference Figure 1 and Figure 8 As shown, the getter conveying structure also includes a housing 5, which houses a vacuum source, which can be considered a vacuum pump. The side wall of the housing 5 has a first mounting hole. An outlet connector 3 is connected to the end of the getter pipe 1 away from the inlet connector 2. The outlet connector 3 is made of an elastically deformable material, such as rubber. The outlet connector 3 includes a sealing part 31 at its end. The diameter of the sealing part 31 gradually decreases towards the direction away from the getter pipe 1. The sealing part 31 abuts against the edge of the first mounting hole, thereby sealing the first mounting hole. The air duct of the vacuum source is connected to the outlet connector 3, thus connecting the vacuum source and the getter pipe 1.

[0037] The housing 5 is also connected to a connecting plate 51. The connecting plate 51 includes a second mounting hole, through which the air outlet connector 3 passes. The air outlet connector 3 also includes a blocking part 32. The second mounting hole corresponds to the position of the first mounting hole. The air outlet connector 3 passes through the second mounting hole. The air outlet connector 3 also includes a blocking part 32. There is a gap between the blocking part 32 and the sealing part 31. The connecting plate 51 is clamped between the blocking part 32 and the sealing part 31. That is, the edge of the second mounting hole is located between the blocking part 32 and the sealing part 31, thereby fixing the position of the air outlet connector 3.

[0038] When in use, after the vacuum source is started, the air inlet end of the suction pipe 1 generates negative pressure, so that the impurities can enter the collection chamber through the collection space and the opening 42 under the influence of negative pressure. Driven by the vacuum source and the blowing component, the impurities pass through the air inlet connector 2 and the suction pipe 1 in sequence and enter the air duct of the vacuum source.

[0039] This utility model discloses a waste-collecting and conveying structure. By setting the diameter of the first channel 24 in the air inlet connector 2 to gradually decrease towards the waste-collecting pipe 1, and the diameter of the second channel 25 to gradually increase towards the waste-collecting pipe 1, part of the air inlet channel 23 of the air inlet connector 2 is formed into a funnel shape. This causes the negative pressure in the first channel 24 to gradually increase, while the air blower can introduce airflow towards the air inlet connector 2. Thus, under the cooperation of negative pressure and airflow, impurities can be evenly entered into the waste-collecting pipe 1, avoiding the blockage of the waste-collecting pipe 1 and the air inlet connector 2 by impurities, and solving the adverse consequences of reduced spinning quality caused by the blockage of the waste-collecting pipe 1.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
