Description

Technical Field

[0001] This utility model belongs to the field of sock machine technology, and specifically relates to a sock-raising assembly and a sock-raising device using the same. Background Technology

[0002] Sock knitting mainly involves two processes: knitting the sock body and sewing the toe. After knitting, the sock body is transferred from the sock transfer mechanism to the sewing mechanism. Before sewing the toe, a sock straightening device is needed to turn the sock inside out. Specifically, the sock straightening tube uses negative pressure to absorb the sock body and pushes it upwards to turn it inside out.

[0003] In the prior art, sock-flipping devices generally use a sock-flipping tube fixed on a lifting base to flip the socks. However, the connection between the sock-flipping tube and the lifting base in most devices is not flexible and detachable, making it impossible to quickly assemble and disassemble the sock-flipping tube. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a sock-pressing component.

[0005] To achieve the innovative objectives of this utility model, the following technical solutions can be used: A sock-cleaning assembly includes a lifting seat, a sock-cleaning tube that is radially limited to the lifting seat, at least one limiting groove on the sock-cleaning tube, and a locking body on the lifting seat that cooperates with the limiting groove. The locking body can extend into the limiting groove to prevent the sock-cleaning tube from moving axially. A locking body movable positioning mechanism is provided between the locking body and the lifting seat.

[0006] The sock-turning assembly of this utility model is used to turn the sock body inside out before sewing. The upper end of its sock-turning tube can suck in the hanging sock body and push it upward to turn it inside out. The lower end of the sock-turning tube is inserted into the lifting seat. The clamping body can move radially along the sock-turning tube. The front end of the clamping body is inserted into the limiting groove of the sock-turning tube to achieve axial limiting. The clamping body movable positioning mechanism is used to limit the movement path of the clamping body and at the same time make it tend to move towards the sock-turning tube to insert into the limiting groove. The connection between the sock-turning tube and the lifting seat of this application has flexible detachability.

[0007] In the above-mentioned sock-conditioning assembly, the card body movable positioning mechanism includes a guide structure disposed between the card body and the lifting seat, which restricts the card body to move only radially along the axis of the sock tube, and a locking structure is provided between the card body and the lifting seat.

[0008] The guide structure is used to limit the movement path of the card body to the radial direction of the stocking sleeve, while the locking structure is used to control the disengagement movement of the card body, so that the card body has the tendency to move towards the stocking sleeve so that the front end is inserted into the limiting groove and held.

[0009] In the above-mentioned sock assembly, the guide structure includes a guide groove, the card body is disposed in the guide groove, a limiting structure is provided between the guide groove and the card body to prevent the card body from moving radially along the axis of the guide groove, and a locking structure is provided between the card body and the lifting seat to prevent the card body from shifting.

[0010] The guide groove is located on the top of the lifting seat, and its length direction is adapted to the radial direction of the stocking tube. The card body slides in the guide groove, and the limiting structure is used to limit the card body in the guide groove.

[0011] In the above-mentioned sock assembly, the limiting structure includes a plurality of limiting pressure bodies respectively disposed on both sides of the card body; Alternatively, the limiting structure includes at least two strip-shaped guide holes respectively provided on the card body, and each strip-shaped guide hole is provided with a guide body fixed on the lifting seat; Alternatively, the limiting structure may include a dovetail guide structure disposed between the side of the guide groove and the side of the card body.

[0012] The limiting pressure body can be two bolts respectively set on both sides of the clamp body, with the vertical projection of the bolt heads coinciding with the clamp body portion. Ideally, the bolt heads and the clamp body should be in close contact or have a very small gap, pressing the clamp body into the guide groove. As a second option, the limiting structure can also be a guide body perpendicular to the length direction of the clamp body, which transversely penetrates a strip-shaped guide hole to limit the clamp body in the thickness direction. As a third option, a dovetail guide structure makes the guide groove a trapezoidal structure with a smaller top and larger bottom cross-section, with the clamp body located within this guide groove, achieving limiting in the thickness direction.

[0013] In the above-mentioned sock assembly, the locking structure includes an elastic element disposed between the locking body and the guide groove. The guide groove is provided with an elastic element mounting groove. The locking body is provided with a force-receiving body that can extend into the elastic element mounting groove and move along its axial direction. One end of the elastic element abuts against the force-receiving body, and the other end abuts against one end of the elastic element mounting groove.

[0014] The force-bearing body is vertically positioned at the bottom of the card body, and the elastic element is located on the side of the force-bearing body away from the stocking tube. It applies a thrust towards the stocking tube to the force-bearing body, causing the front end of the card body to tend to move towards the stocking tube.

[0015] In the above-mentioned sock assembly, both the clip body and the force-receiving body are sheet-shaped, and the clip body is provided with an unlocking force-applying hole located between the force-receiving body and the clip body.

[0016] The card body is rectangular and flat. The force-bearing body is formed by cutting a U-shaped trajectory on the card body and bending it downwards at 90 degrees. The position where the force-bearing body is cut off on the card body forms the unlocking force hole. This hole can be used to insert a tool such as a screwdriver to easily move the card body so that the front end of the card body is away from the limiting groove.

[0017] In the above-mentioned sock-conditioning assembly, the upper end of the sock-conditioning tube is provided with an oblique opening, the limiting groove is an annular groove, and an angle limiting structure is provided between the sock-conditioning tube and the lifting seat to perform circumferential positioning of the rotating sock-conditioning tube after the oblique opening is adjusted.

[0018] The upper end of the stocking tube is designed with an angled opening to facilitate the intake of the stocking body to be sewn. In order to make it easy to adjust the orientation of the angled opening, the limiting groove is set 360 degrees around the outer wall of the stocking tube, so that the clamping body will not restrict the circumferential rotation of the stocking tube. After the rotation is adjusted to the correct position, it is locked by the angle limiting structure.

[0019] In the above-mentioned sock-conditioning assembly, the angle limiting structure includes at least two U-shaped downward-opening angle limiting holes distributed circumferentially at the lower end of the sock-conditioning tube, and at least one angle limiting hole is provided with an angle limiting pin, which is fixed in the angle limiting pin hole of the lifting seat.

[0020] Angle limiting holes extend axially upward from the lower end of the stocking tube. Angle limiting pins are located in the angle limiting holes, allowing the stocking tube to move axially a certain distance, but restricting circumferential rotation. The angle limiting pins are similar to bolts and are detachably installed in the lifting base by threads. Preferably, the number of angle limiting holes is even to ensure symmetrical arrangement in pairs. In addition, the lifting base is also provided with screw-in through holes symmetrical to the angle limiting pin holes. Tools such as screwdrivers can be sequentially passed through the screw-in through holes, angle limiting holes and angle limiting pins to make contact.

[0021] In the above-mentioned sock-conditioning assembly, the lower end of the sock-conditioning tube is installed in the sock-conditioning tube mounting hole of the lifting seat. The sock-conditioning tube mounting hole is provided with a first annular inner step. The lower end of the sock-conditioning tube abuts against the first annular inner step. The sock-conditioning tube is connected to the negative pressure port through the sock-conditioning tube mounting hole.

[0022] The lifting base is provided with a vertical through-hole for mounting the stocking tube. The upper end of the mounting hole is connected to the stocking tube, and the lower end is provided with a negative pressure port for connecting the air extraction guide tube. In other words, the separate design of the stocking tube, the lifting base and the air extraction guide tube helps to reduce the difficulty of the process.

[0023] In the above-mentioned sock-cleaning assembly, the negative pressure port is connected to the air extraction guide tube, the negative pressure port is provided with a second annular inner step, one end of the air extraction guide tube is fixed on the second annular inner step, and a sealing ring groove is provided between the air extraction guide tube and the second annular inner step; the first annular inner step is provided with an annular boss located inside the sock-cleaning tube, and the annular boss is provided with a chamfer.

[0024] The air extraction guide tube is fixed inside the negative pressure extraction port. The sealing ring groove is preferably set on the outer wall of the air extraction guide tube. The sealing ring is set to achieve circumferential sealing between the air extraction guide tube and the negative pressure extraction port. The first annular inner step and the annular boss form an L-shaped structure. The lower end of the stocking tube is fixed inside the L-shaped structure. Its inner and outer sides and bottom side are all in contact with the L-shaped structure to ensure the sealing effect. In addition, a chamfer to prevent negative pressure tearing is also provided on the inner side of the annular boss.

[0025] Another objective of this invention is to address the aforementioned problems in the existing technology by proposing a sock-cleaning device.

[0026] To achieve this innovative objective of this utility model, the following technical solutions can be used: A sock-cleaning device includes a housing body, within which the aforementioned sock-cleaning assembly is disposed. A lifting seat is connected to a screw-nut lifting unit. A main guide rod and a secondary guide rod are disposed between the screw-nut lifting unit and the sock-cleaning cylinder. The lifting seat has an axially penetrating guide hole and a side-open guide groove. The main guide rod is slidably connected in the guide hole, and the secondary guide rod is slidably connected in the guide groove. The main guide rod, secondary guide rod, sock-cleaning cylinder, and the lifting screw of the screw-nut lifting unit are arranged in a rhomboid pattern.

[0027] This utility model's sock-cleaning device mainly consists of a main outer shell and an internal sock-cleaning assembly. The main outer shell has a corresponding mounting structure on its side, allowing it to be installed at the appropriate position on a sock machine. The main outer shell is hollow, with through holes at both ends allowing the sock-cleaning tube and the air extraction guide pipe to pass through. The lifting seat is guided by a main guide rod and a secondary guide rod, both ends of which are fixedly connected to the ends of the main outer shell. Guidance is provided by a main and a secondary double-axis guide rod. The main guide rod, secondary guide rod, sock-cleaning tube, and lifting screw are arranged in a diamond pattern, reducing manufacturing difficulty and improving stability while maintaining a compact space. Furthermore, the secondary guide rod is located in an open guide groove on the side, facilitating radial disassembly and assembly. Of course, the main outer shell also has a movable pressure plate that can support the sock with the seam allowance and suspend it at the bottom of the upper sock-cleaning device; this is existing technology and will not be elaborated upon further.

[0028] In the above-mentioned sock-lowering device, the screw nut lifting unit includes a rotary driver fixed to the bottom of the outer shell body via a motor base. The rotating shaft of the rotary driver is connected to the lifting screw. The lifting screw meshes with the screw thread hole of the lifting seat. The top of the outer shell body is provided with a positioning hole, and the upper end of the lifting screw is rotatably connected to the positioning hole.

[0029] The lifting screw engages with the screw hole on the lifting seat. The upper end of the lifting screw is rotatably connected to the positioning hole on the top of the main body. For optimization, a wear-resistant ring or bearing assembly is provided within this positioning hole. The upper end of the positioning hole has an annular flare, within which a top cover is detachably installed. This top cover can be easily removed for the installation and removal of the wear-resistant ring or bearing assembly. The lower end of the lifting screw is connected in the same direction to the output shaft of the rotary driver. The rotary driver drives the rotation of the lifting screw, thereby achieving the lifting and lowering of the lifting seat.

[0030] In the above-mentioned sock-feeling device, the outer diameter of the main guide rod is larger than the outer diameter of the auxiliary guide rod. The auxiliary guide rod has an axially extending cross-section on its side, which is flush with the opening of the guide side groove. A wear-resistant collar is provided between the guide hole and the main guide rod. A wear-resistant semi-ring with a U-shaped cross-section is provided in the guide side groove. An anti-slip protrusion is provided on the guide side groove to prevent the wear-resistant semi-ring from slipping upward. The auxiliary guide rod and the wear-resistant semi-ring are in sliding fit.

[0031] The cut surface is used to prevent the side of the secondary guide rod from contacting the inner wall of the housing body. The wear-resistant collar and wear-resistant half ring are used to increase wear resistance and extend service life. Both of them are detachable, which facilitates the replacement of vulnerable parts.

[0032] As an optimization, the upper end of the outer shell body is provided with an L-shaped sock-receiving baffle on the sock-receiving side, with the opening of the sock-receiving baffle facing away from the sock-sorting tube. The sock-receiving baffle is detachably fixed to the sock-receiving side of the outer shell body via an installation section, with its opening facing the sock body to be sewn, confining the sock body within the opening, which helps the sock-sorting tube to suck in the sock body under negative pressure.

[0033] As an optimization, an inspection port is provided on the side of the lower end of the main body of the outer shell. The inspection port is closed by a detachable switch door, which facilitates inspection and maintenance when the lifting seat is lowered to the lowest position.

[0034] As an optimization, the upper end of the outer shell body is detachably fixed with an annular circumferential seal, and the sock tube is fitted with the circumferential seal to improve the sealing degree of the circuit.

[0035] As an optimization, a sealing sleeve is connected to the lower end of the outer shell body. The sealing sleeve is coaxially connected to the vacuum port. The suction guide tube passes through the sealing sleeve. An upper sealing ring is provided at the upper end of the sealing sleeve and the bottom of the outer shell body. A lower sealing assembly can also be provided between the suction guide tube and the sealing sleeve. The sealing sleeve protects the suction sealing tube and ensures the seal between the suction guide tube and the vacuum port.

[0036] Compared with the prior art, the present invention has the following main advantages: 1. The lower end of the sock-cleaning tube is inserted into the lifting seat. The clamping body can move radially along the sock-cleaning tube. The front end of the clamping body is inserted into the limiting groove of the sock-cleaning tube to achieve axial limiting. The clamping body movable positioning mechanism is used to limit the movement path of the clamping body and make it tend to move towards the sock-cleaning tube to insert into the limiting groove. The connection between the sock-cleaning tube and the lifting seat in this application has flexible detachability.

[0037] 2. The card body is sheet-shaped. The force-bearing body is formed by cutting out a U-shaped trajectory on the card body and bending it downwards at 90 degrees. The position where the force-bearing body is cut off on the card body forms the unlocking force hole. This hole can easily move the card body to make the front end of the card body leave the limiting groove.

[0038] 3. To facilitate adjustment of the slanted opening orientation, the limiting groove is set 360 degrees circumferentially along the outer wall of the stocking tube, so that the locking body does not restrict the circumferential rotation of the stocking tube. After the rotation is adjusted to the correct position, it is locked by the angle limiting structure.

[0039] 4. Angle limiting holes extend axially upward from the lower end of the stocking tube. Angle limiting pins are located in the angle limiting holes, allowing the stocking tube to move axially a certain distance, but restricting circumferential rotation. The number of angle limiting holes is even, ensuring that they are arranged symmetrically in pairs. A screwdriver can be inserted into the angle limiting hole opposite to the angle limiting pin to turn the angle limiting pin.

[0040] 5. This utility model separates the sock tube, the lifting seat, and the air extraction guide tube into separate parts, which helps to reduce the difficulty of the manufacturing process.

[0041] 6. The two ends of the main guide rod and the auxiliary guide rod are fixedly connected to the two ends of the outer shell body. They are guided by a main and an auxiliary double optical axis guide rod. While maintaining a compact space, the process difficulty is reduced and the stability is improved. Moreover, the auxiliary guide rod is located in the open guide side groove, which facilitates radial disassembly and assembly.

[0042] 7. The cut surface is used to prevent the side of the auxiliary guide rod from contacting the inner wall of the housing body. The wear-resistant collar and wear-resistant half ring are used to increase wear resistance and extend service life. Both of them are detachable, which facilitates the replacement of vulnerable parts.

[0043] 8. The upper end of the outer shell body is provided with an L-shaped sock receiving baffle on the sock receiving side. The opening of the sock receiving baffle faces away from the sock straightening tube, which can confine the sock body within the opening and help the sock straightening tube to suck in the sock body under negative pressure.

[0044] 9. An inspection port is provided on the side of the lower end of the main body of the outer shell, which facilitates inspection and maintenance when the lifting seat is lowered to the lowest position. Attached Figure Description

Detailed Implementation

[0047] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0048] Specific implementation examples Figures 1-9As shown, this sock-cleaning device includes a main shell 28, within which a sock-cleaning assembly 29 is provided. The sock-cleaning assembly 29 includes a lifting seat 1, a sock-cleaning tube 2 radially limited and connected to the lifting seat 1, a limiting groove 3 on the sock-cleaning tube 2, and a locking body 4 on the lifting seat 1 that cooperates with the limiting groove 3. The locking body 4 can extend into the limiting groove 3 to prevent the sock-cleaning tube 2 from moving axially. A locking body movable positioning mechanism 5 is provided between the locking body 4 and the lifting seat 1. The lifting seat 1 is connected to a screw nut lifting unit 31. A main guide rod 44 and a secondary guide rod 45 are provided between the screw nut lifting unit 31 and the sock-cleaning tube 2. The lifting seat 1 has a guide hole 46 and a side-open guide groove 47 axially penetrating through it. The main guide rod 44 is slidably connected in the guide hole 46, and the secondary guide rod 45 is slidably connected in the guide groove 47. The main guide rod 44, the secondary guide rod 45, the sock-cleaning tube 2, and the lifting screw 33 of the screw nut lifting unit 31 are arranged in a rhomboid shape.

[0049] Specifically, the sock-cleaning device mainly consists of a main outer shell 28 and an internal sock-cleaning assembly 29. The main outer shell 28 has a corresponding mounting structure on its side, allowing it to be installed at the corresponding position on the sock machine. The main outer shell 28 is hollow inside, and both ends have through holes that allow the sock-cleaning tube 2 and the air extraction guide pipe 23 to pass through. The lifting seat 1 is guided by a main guide rod 44 and a secondary guide rod 45. The two ends of the main guide rod 44 and the secondary guide rod 45 are fixedly connected to the two ends of the main outer shell 28 and guided by a main and a secondary double optical axis guide rod. The main guide rod 44, the secondary guide rod 45, the sock-cleaning tube 2, and the lifting screw 33 are arranged in a diamond shape. While maintaining a compact space, the manufacturing difficulty is reduced and the stability is improved. Moreover, the secondary guide rod 45 is located in the open guide side groove 47, which facilitates radial disassembly and assembly. The screw nut lifting unit 31 is used to provide the specific lifting driving force, and its driving screw 33 is parallel to the main guide rod 44 and the secondary guide rod 45. The upper end of the sock-cleaning tube 2 of the sock-cleaning assembly 29 can suck in the hanging sock and push it upward to turn it over. The lower end of the sock-cleaning tube 2 is inserted into the lifting seat 1. The clamping body 4 can move radially along the sock-cleaning tube 2. The front end of the clamping body 4 is inserted into the limiting groove 3 of the sock-cleaning tube 2 to achieve axial limiting. The clamping body movable positioning mechanism 5 is used to limit the movement path of the clamping body 4, and at the same time make it tend to move towards the sock-cleaning tube 2 to insert into the limiting groove 3. The connection between the sock-cleaning tube 2 and the lifting seat 1 in this application has flexible detachability.

[0050] Furthermore, the outer diameter of the main guide rod 44 is larger than that of the secondary guide rod 45. The secondary guide rod 45 has an axially extending cross-section 36 on its side, which is flush with the opening of the guide side groove 47 to prevent contact with the inner wall of the housing body 28. A wear-resistant collar 48 is provided between the guide hole 46 and the main guide rod 44. A wear-resistant semi-ring 49 with a U-shaped cross-section is provided in the guide side groove 47. An anti-detachment protrusion 50 is provided on the guide side groove 47 to prevent the wear-resistant semi-ring 49 from detaching upward. The secondary guide rod 45 and the wear-resistant semi-ring 49 are in sliding fit. Moreover, both the wear-resistant collar 48 and the wear-resistant semi-ring 49 are detachable, which facilitates the replacement of vulnerable parts.

[0051] like Figure 5 , 6 As shown in Figures 7 and 8, the card body movable positioning mechanism 5 includes a guide structure 6 disposed between the card body 4 and the lifting seat 1, which restricts the card body 4 to move radially only along the axis of the stocking sleeve 2. A locking structure 7 is provided between the card body 4 and the lifting seat 1. The guide structure 6 includes a guide groove 8, in which the card body 4 is disposed. A limiting structure 9 is provided between the guide groove 8 and the card body 4 to prevent the card body 4 from moving radially along the axis of the guide groove 8. A locking structure 7 is provided between the card body 4 and the lifting seat 1 to prevent the card body 4 from shifting. The limiting structure 9 includes a plurality of limiting pressure bodies 10 respectively disposed on both sides of the card body 4.

[0052] Specifically, the guide structure 6 is used to limit the movement path of the card body 4 to the radial direction of the stocking sleeve 2, and the locking structure 7 is used to control the disengagement movement of the card body 4, so that the card body 4 tends to move towards the stocking sleeve 2, so that the front end is inserted into the limiting groove 3 and held therein. The guide groove 8 is opened at the top of the lifting seat 1, and its length direction is adapted to the radial direction of the stocking sleeve 2. The card body 4 slides in the guide groove 8, and the limiting structure 9 is used to limit the card body 4 within the guide groove 8. The limiting pressure body 10 consists of two sets of bolts respectively set on both sides of the card body 4, and the vertical projection of the bolt head coincides with part of the card body 4.

[0053] like Figure 2 , 3 As shown, the locking structure 7 includes an elastic element 11 disposed between the locking body 4 and the guide groove 8. The guide groove 8 has an elastic element mounting groove 12. The locking body 4 has a force-receiving body 13 that can extend into the elastic element mounting groove 12 and move along its axial direction. One end of the elastic element 11 abuts against the force-receiving body 13, and the other end abuts against one end of the elastic element mounting groove 12. Both the locking body 4 and the force-receiving body 13 are plate-shaped. The locking body 4 has an unlocking force-applying hole 14 located between the force-receiving body 13 and the locking body 4. The front end of the locking body 4 has an arc-shaped surface that adapts to the limiting groove 3.

[0054] Specifically, the force-receiving body 13 is vertically disposed at the bottom of the card body 4, and the elastic element 11 is located on the side of the force-receiving body 13 away from the stocking sleeve 2, applying a pushing force to the force-receiving body 13 towards the stocking sleeve 2, causing the front end of the card body 4 to tend to move towards the stocking sleeve 2. The card body 4 is sheet-shaped, and the force-receiving body 13 is formed by cutting a U-shaped trajectory on the card body 4 and bending it downwards at 90 degrees. The location where the force-receiving body 13 is cut on the card body 4 forms the unlocking force-applying hole 14, which can be used to insert a tool such as a screwdriver, so that the card body 4 can be moved to make the front end of the card body 4 leave the limiting groove 3.

[0055] like Figure 2 , 4 As shown in Figure 9, the upper end of the stocking tube 2 is provided with a slanted opening 15, and the limiting groove 3 is an annular groove. An angle limiting structure 16 is provided between the stocking tube 2 and the lifting seat 1 to perform circumferential positioning of the rotating stocking tube 2 after the slanted opening 15 is adjusted. The angle limiting structure 16 includes two symmetrically arranged angle limiting holes 17 with U-shaped openings facing downwards, distributed circumferentially at the lower end of the stocking tube 2. An angle limiting pin 18 is provided in the angle limiting hole 17 near the lead screw nut lifting unit 31, and the angle limiting pin 18 is fixed in the angle limiting pin hole 19 of the lifting seat 1.

[0056] Specifically, the upper end of the stocking tube 2 is designed with a slanted opening 15 to facilitate the intake of the stocking body to be sewn. To facilitate adjustment of the orientation of the slanted opening 15, the limiting groove 3 is set 360 degrees circumferentially along the outer wall of the stocking tube 2, so that the locking body 4 does not restrict the circumferential rotation of the stocking tube 2. After the rotation is adjusted to the correct position, it is locked by the angle limiting structure 16. The angle limiting hole 17 extends axially upward from the lower end of the stocking tube 2, and the angle limiting pin 18 is located in the angle limiting hole 17, allowing the stocking tube 2 to move axially a certain distance, but restricting circumferential rotation. The angle limiting pin 18 is similar to a bolt and is detachably installed in the lifting seat 1 by threads. The two angle limiting holes 17 are arranged symmetrically. In addition, the lifting seat 1 is also provided with a screw-in through hole 51 symmetrical to the angle limiting pin hole 19. A screwdriver can be sequentially passed through the screw-in through hole 51, the angle limiting hole 17 and the angle limiting pin 18 to make contact.

[0057] like Figure 2 , 7As shown, the lower end of the sock-cleaning tube 2 is installed in the sock-cleaning tube mounting hole 20 of the lifting seat 1. The sock-cleaning tube mounting hole 20 is provided with a first annular inner step 21. The lower end of the sock-cleaning tube 2 abuts against the first annular inner step 21. The sock-cleaning tube 2 is connected to the vacuum suction port 22 through the sock-cleaning tube mounting hole 20. The vacuum suction port 22 is connected to the suction guide pipe 23. The vacuum suction port 22 is provided with a second annular inner step 24. One end of the suction guide pipe 23 is fixed on the second annular inner step 24. A sealing ring groove 25 is provided between the suction guide pipe 23 and the second annular inner step 24. The first annular inner step 21 is provided with an annular boss 26 located inside the sock-cleaning tube 2. The annular boss 26 is provided with a chamfer 27.

[0058] Specifically, the lifting base 1 is provided with a vertical through-hole 20 for mounting the stocking tube. The upper end of the mounting hole is connected to the stocking tube 2, and the lower end is provided with a negative pressure port 22 for connecting the suction guide tube 23. In other words, the separate design of the stocking tube 2, the lifting base 1, and the suction guide tube 23 helps to reduce the difficulty of the process. The suction guide tube 23 is fixed in the negative pressure port 22, and the sealing ring groove 25 is provided on the outer wall of the suction guide tube 23. The sealing ring is provided to achieve circumferential sealing between the suction guide tube 23 and the negative pressure port 22. The first annular inner step 21 and the annular boss 26 form an L-shaped structure. The lower end of the stocking tube 2 is fixed in the L-shaped structure, and its inner and outer sides and bottom side are all in contact with the L-shaped structure to ensure the sealing effect. In addition, a chamfer 27 for preventing negative pressure tearing is provided on the inner side of the annular boss 26.

[0059] like Figure 1 , 2 As shown in 4, 5, 6, and 7, the lead screw nut lifting unit 31 includes a rotary driver 32 fixed to the bottom of the outer shell 28 via a motor base. The rotating shaft of the rotary driver 32 is connected to the lifting lead screw 33. The lifting lead screw 33 engages with the lead screw hole 34 of the lifting seat 1. The top of the outer shell 28 is provided with a positioning hole 35, and the upper end of the lifting lead screw 33 is rotatably connected to the positioning hole 35.

[0060] Specifically, the lifting screw 33 engages with the screw hole 34 on the lifting seat 1. The upper end of the lifting screw 33 is rotatably connected to the positioning hole 35 on the top of the outer casing 28. A wear-resistant ring 41 is provided in the positioning hole 35, and an annular flared opening 42 is provided at the upper end of the positioning hole 35. A top cover 43 is detachably installed in the annular flared opening 42, and the top cover 43 can be easily removed for the installation and removal of the wear-resistant ring 41. The lower end of the lifting screw 33 is connected in the same direction to the output shaft of the rotary driver 32. The rotary driver 32 drives the rotation of the lifting screw 33, thereby realizing the lifting and lowering of the lifting seat 1.

[0061] As an optimization of this embodiment, an L-shaped sock-receiving baffle 37 is provided on the upper end of the outer shell body 28 on the sock-receiving side, with the opening of the sock-receiving baffle 37 facing away from the sock-sorting tube 2. The sock-receiving baffle 37 is detachably fixed to the sock-receiving side of the outer shell body 28 via an installation section, with its opening facing the sock body to be sewn, confining the sock body within the opening, which helps the sock-sorting tube 2 to suck in the sock body under negative pressure.

[0062] As an optimization of this embodiment, an inspection port 38 is provided on the side of the lower end of the outer shell body 28. The inspection port 38 is closed by a detachable switch door 39, which facilitates inspection and maintenance when the lifting seat 1 is lowered to the lowest position. An annular circumferential seal 40 is detachably fixed to the upper end of the outer shell body 28, and the sock sleeve 2 passes through the circumferential seal 40 to improve the circuit sealing degree.

[0063] As an optimization of this embodiment, a sealing sleeve 52 is connected to the lower end of the outer shell 28. The sealing sleeve 52 is coaxially connected to the vacuum port 22. The suction guide tube 23 passes through the sealing sleeve 52. An upper sealing ring 53 is provided between the upper end of the sealing sleeve 52 and the bottom end of the outer shell 28. A lower sealing assembly can also be further provided between the suction guide tube 23 and the sealing sleeve 52. The sealing sleeve 52 can protect the suction guide tube 23 on the one hand, and ensure the sealing between the suction guide tube 23 and the vacuum port 22 on the other hand.

[0064] Specific working principle: When the stocking tube 2 needs to be raised or lowered, the rotary driver 32 is started, driving the lifting screw 33 to rotate forward or reverse. The lifting seat 1 moves up and down along the main guide rod 44 and the auxiliary guide rod 45, which in turn drives the stocking tube 2 on it to rise and fall.

[0065] When it is necessary to remove the stocking sleeve 2, insert the tool into the unlocking force hole 14, and move the locking body 4 away from the stocking sleeve 2. The front end of the locking body 4 leaves the limiting groove 3, thus releasing the axial limitation on the stocking sleeve 2.

[0066] When it is necessary to rotate and adjust the stocking tube 2, pass the screwdriver through the outer angle limiting hole 17, rotate the angle limiting pin 18 and remove it, which releases the circumferential rotation limit on the stocking tube 2. After rotating it to the correct position, reinstall the angle limiting pin 18.
