Description

Technical Field

[0001] The utility model relates to the technical field of hosiery knitting machines, in particular to a double-needle hosiery knitting machine. Background Art

[0002] A double-needle simple hosiery machine is a type of equipment used for sock production. It utilizes two needle cylinders operating simultaneously, improving weaving efficiency and quality. It primarily consists of a frame, needle cylinders, yarn guides, a fabric delivery device, and an electrical control system. It enables efficient and stable sock production and is suitable for small and medium-sized manufacturers.

[0003] Double-needle simple hosiery machines usually have a wire feeding mechanism, which transports the yarn to the knitting mechanism. Since the wire feeding mechanism on traditional double-needle simple hosiery machines lacks constraints on the yarn on the bobbin, when the yarn breaks during the feeding process, the yarn wrapped on the wire feeding bobbin will jump due to elasticity or even become loose, affecting subsequent textile operations. Utility Model Content

[0004] The purpose of the utility model is to provide a double-needle simple hosiery machine which can provide binding for the yarn on the bobbin when feeding the yarn, thereby effectively solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.

[0006] A double-needle simple hosiery machine includes a base, a frame, a bobbin and a pressure roller. The base is fixed to the side of the frame. Two upright frames are vertically fixed to the upper surface of the base. The bobbin is rotatably installed on the top of the two upright frames. Two upright posts are vertically fixed to the upper surface of the base. Sliding seats are slidably sleeved on the two upright posts. A cantilever is fixed between the two sliding seats. A pressure roller is rotatably installed below the cantilever through a U-shaped frame. The pressure roller is arranged directly above the bobbin and contacts the outer edge wall of the bobbin.

[0007] It can be seen that during the yarn conveying process, the pressure roller is pressed tightly against the bobbin, and both the bobbin and the pressure roller have the ability to rotate to ensure the smoothness of yarn conveying. When the yarn breaks, the downward pressure of the pressure roller can effectively prevent the yarn from jumping and loosening.

[0008] Furthermore, mounting seats are fixed on the top of the two upright frames, and both mounting seats are provided with open semicircular grooves. The two ends of the shaft rod on the bobbin are matched and placed in the semicircular grooves on both sides, and the two end faces of the shaft rod slide and fit with the inner end faces of the two semicircular grooves respectively.

[0009] Furthermore, bearings are fixedly mounted on the outer wall of the shaft near its two ends, and the outer edge walls of the bearings correspond to the inner edge walls of the semicircular groove.

[0010] Furthermore, a rack is vertically fixed under one of the sliding seats, and a vertical frame is vertically fixed on the upper surface of the base near the rack. A horizontally extending rotating shaft is rotatably installed at the top of the vertical frame. A gear is fixed at one end of the rotating shaft and a rocker is installed at the other end. The gear is meshed with the rack.

[0011] Furthermore, a mounting block is fixed on the side surface of the vertical frame and below the gear. The mounting block is provided with a horizontally penetrating sliding hole. A clamping rod is slidably inserted into the sliding hole, and the clamping rod is in contact with the bottom end of the rack.

[0012] Furthermore, anti-drop caps are fixed to the top ends of the two columns, and the diameter of the anti-drop caps is larger than the diameter of the hole in the sliding seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] 1. In the process of conveying yarn, the pressure roller of the utility model is pressed tightly on the bobbin. Both the bobbin and the pressure roller have the ability to rotate to ensure the smoothness of yarn conveying. When the yarn breaks, the downward pressure of the pressure roller can effectively prevent the yarn from jumping and loosening.

[0015] 2. In the utility model, the sliding seat is slidably mounted on the column to realize the lifting and lowering adjustment capability of the pressure roller, and the pressure roller is arranged directly above the bobbin, and the column is arranged vertically, so that gravity can automatically cause the pressure roller to be pressed tightly against the bobbin. As the yarn is continuously supplied, the overall diameter of the bobbin decreases, and the pressure roller automatically descends under the action of gravity and always maintains a state of resistance with the bobbin, realizing adaptive descending adjustment of the pressure roller. There is no need to provide an additional driving source to drive the pressure roller to descend to adapt to the change in the overall diameter of the bobbin, saving equipment cost investment, and the overall structural layout is simple and reasonable, with high practicality.

[0016] 3. The utility model completes the installation of the bobbin by matching and inserting the two ends of the shaft rod into the semicircular groove. The two ends of the bobbin are pulled upward to make the two ends of the shaft rod disengage from the semicircular groove, and the bobbin can be removed, thereby making the disassembly, assembly and replacement of the bobbin more convenient. Under the pressing action of the pressure roller, the bobbin is guaranteed not to jump up and down, ensuring the stability of the thread supply. The pressure roller serves as a binding member to prevent the yarn from jumping loose, and also as a pressure member to limit the bobbin from jumping up and down, killing two birds with one stone.

[0017] 4. The utility model drives the rotating shaft and the gear to rotate by shaking the shaking plate, and the rotating gear engages to drive the rack to move upward, thereby driving the sliding seat on that side to move upward along the column. Under the connection between the cantilever and the U-shaped frame, the pressure roller is driven to move upward, making space above the bobbin, making it convenient to replace the bobbin, and the adjustment process is easy and labor-saving. In addition, when the pressure roller is adjusted upward until the bottom end of the rack is higher than the clamping rod, the clamping rod is pushed to the side of the rack, and the clamping rod is used to provide a blocking effect on the rack to prevent the pressure roller from moving downward due to its own weight. No manpower is required to maintain the height of the pressure roller, freeing the staff's hands and facilitating the bobbin replacement operation by one person. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-Figure 4 The utility model provides a double-needle simple hosiery machine, including a base 1, a frame 2, a bobbin 3 and a pressure roller 5. The base 1 is fixed to the side of the frame 2, and two upright frames 11 are vertically fixed to the upper surface of the base 1. The bobbin 3 is rotatably installed on the top of the two upright frames 11. Two columns 12 are vertically fixed to the upper surface of the base 1, and a sliding seat 4 is slidably sleeved on the two columns 12. A cantilever 41 is fixed between the two sliding seats 4, and a pressure roller 5 is rotatably installed below the cantilever 41 through a U-shaped frame 42. The pressure roller 5 is arranged directly above the bobbin 3, and the pressure roller 5 is in contact with the outer edge wall of the bobbin 3. In addition, the other components of the double-needle simple hosiery machine provided by the utility model are consistent with those in the prior art, and the specific shapes, structures and working principles of other components are not repeated in this application.

[0027] When the double-needle simple hosiery machine is working, the yarn on the bobbin 3 is transported to the knitting mechanism for hosiery processing. During the yarn transportation process, the pressure roller 5 is pressed tightly on the bobbin 3. The bobbin 3 and the pressure roller 5 both have the ability to rotate to ensure the smoothness of yarn transportation. When the yarn breaks, the downward pressure of the pressure roller 5 can effectively prevent the yarn from jumping and loosening.

[0028] In addition, the sliding seat 4 is slidably mounted on the column 12 to realize the lifting and lowering adjustment capability of the pressure roller 5, and the pressure roller 5 is arranged directly above the bobbin 3, and the column 12 is arranged vertically, so that gravity can automatically cause the pressure roller 5 to be pressed tightly against the bobbin 3. As the yarn is continuously supplied, the overall diameter of the bobbin 3 decreases, and the pressure roller 5 automatically descends under the action of gravity, and always maintains a state of resistance with the bobbin 3, realizing the adaptive descending adjustment of the pressure roller 5. There is no need to provide an additional driving source to drive the pressure roller 5 to descend to adapt to the change in the overall diameter of the bobbin 3, saving equipment cost investment, and the overall structural layout is simple and reasonable, and highly practical.

[0029] When the bobbin 3 needs to be replaced, the pressing roller 5 is pushed upward to make room above the bobbin 3.

[0030] Specifically, a mounting seat 111 is fixed to the top of the two upright frames 11, and an open semicircular groove 112 is provided on the two mounting seats 111. The two ends of the shaft rod 31 on the bobbin 3 are matched and placed in the semicircular grooves 112 on both sides. The top of the semicircular groove 112 is an opening for the shaft rod 31 to pass through. The two end faces of the shaft rod 31 slide and fit with the inner end faces of the two semicircular grooves 112 respectively to limit the bobbin 3 and prevent the bobbin 3 from shifting left and right.

[0031] The installation of the bobbin 3 can be completed by matching the two ends of the shaft rod 31 and inserting them into the semicircular groove 112. The installation of the bobbin 3 can be completed by pulling the two ends of the bobbin 3 upward to make the two ends of the shaft rod 31 disengage from the semicircular groove 112, and the bobbin 3 can be removed, thereby making the disassembly, assembly and replacement of the bobbin 3 more convenient. Under the pressing action of the pressure roller 5, the bobbin 3 is guaranteed not to jump up and down, thereby ensuring the stability of the thread supply. The pressure roller 5 serves as a binding member to prevent the yarn from jumping loose, and also as a pressure member to limit the bobbin 3 from jumping up and down, killing two birds with one stone.

[0032] Specifically, bearings 311 are fixedly mounted on the outer wall of the shaft 31 near its two ends. The outer edge wall of the bearing 311 corresponds to the inner edge wall of the semicircular groove 112. The bearing 311 can ensure that the rotation process of the bobbin 3 is smooth enough.

[0033] Specifically, a rack 62 is vertically fixed under one of the sliding seats 4, and a vertical frame 13 is vertically fixed on the upper surface of the base 1 near the rack 62. A horizontally extending rotating shaft 6 is rotatably installed at the top of the vertical frame 13. A gear 61 is fixed to one end of the rotating shaft 6, and a rocker 63 is installed at the other end. The gear 61 is meshed with the rack 62. When the bobbin 3 needs to be replaced, the rotating shaft 6 and the gear 61 are rotated by shaking the rocker 63. The rotating gear 61 meshes and drives the rack 62 to move upward, thereby driving the sliding seat 4 on that side to move up along the column 12. Under the connection between the cantilever 41 and the U-shaped frame 42, the pressure roller 5 is driven to move up, making room above the bobbin 3, making it convenient to replace the bobbin 3, and the adjustment process is easy and labor-saving.

[0034] Specifically, a mounting block 7 is fixed on the side surface of the vertical frame 13 and below the gear 61. The mounting block 7 is provided with a horizontally penetrating sliding hole 71. A card rod 72 is slidably inserted into the sliding hole 71. The card rod 72 is in contact with the bottom end of the rack 62. When the pressure roller 5 is adjusted upward until the bottom end of the rack 62 is higher than the card rod 72, the card rod 72 is pushed to the side of the rack 62. The card rod 72 provides a blocking effect on the rack 62 to prevent the pressure roller 5 from moving downward due to its own weight. No manpower is required to maintain the height of the pressure roller 5, freeing the staff's hands and facilitating the replacement operation of the bobbin 3 by one person.

[0035] Specifically, anti-drop caps 121 are fixed to the tops of the two columns 12. The diameter of the anti-drop caps 121 is larger than the diameter of the hole in the sliding seat 4. The anti-drop caps 121 are used to block the sliding seat 4 and prevent it from falling off due to excessive upward movement along the columns 12.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
