Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology and relates to a guide rhombus on the upper shell of a double needle tube sock machine. Background Technology

[0002] In the traditional design of double-cylinder sock knitting machines, the guide bevel is usually located at the lower end of the inner wall of the upper cylinder. The beveled structure works in conjunction with the needle feet of the guide plate to guide the movement. However, this motion trajectory control suffers from a problem: the guide plate is supported only at the front end, lacking sufficient support at the rear. This leads to a large torque on the guide plate under stress, affecting its balance and movement stability. Furthermore, the traditional beveled guide causes the needle feet to slide in line contact. The collision between the needle feet and the bevel generates impact vibration, resulting in instantaneous stress concentration at the contact point. Uneven stress on the needle feet easily leads to fatigue cracks, severely impacting the accuracy and stability of the guide plate. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a guide rhombus for the upper housing of a double-needle sock machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A guide rhombus for the upper housing of a double-cylinder sock machine includes an upper cylinder seat. A guide rhombus is provided on the inner wall of the upper cylinder seat at the upper end of the inner wall. The guide rhombus is arranged circumferentially along the inner wall of the upper cylinder seat. A needle guide structure is provided at the end of the guide rhombus that can cooperate with the rear needle of the needle guide piece. The rear needle of the needle guide piece can enter the upper guide surface of the guide rhombus through the needle guide structure. A density rhombus is provided on the inner wall of the upper cylinder seat below the guide rhombus that can cooperate with the front needle of the needle guide piece.

[0005] The upper guide surface provides rear-end support for the guide pin sheet. Compared to the traditional front-end support, the rear-end support utilizes gravity-assisted guidance, enabling the rear pin of the guide pin sheet to obtain stable support in the initial stage of movement. The stability of the guide pin sheet displacement is better. The pin guiding structure can significantly improve the uniformity of force on the rear pin, eliminate local stress concentration in the rear pin, and ensure that there is no impact vibration in the rear pin during displacement, thus ensuring the stability and accuracy of the guide pin sheet.

[0006] In the aforementioned double-needle sock machine upper housing guide rhombus, the needle guide structure includes an arc-shaped guide surface provided from the end of the guide rhombus to the upper guide surface, and the rear needle of the guide needle piece can be moved along the arc-shaped guide surface from the end of the guide rhombus to the upper guide surface of the guide rhombus.

[0007] When the rear pin moves along the arc-shaped guide surface, it achieves surface contact guidance between the rear pin and the arc-shaped guide surface, which can significantly improve the uniformity of force. The contact points are evenly distributed along the tangent of the arc, which can eliminate local stress concentration and ensure that there is no impact vibration during the displacement of the rear pin, thus ensuring the stability and accuracy of the guide pin.

[0008] In the aforementioned guide rhombus of the upper housing of a double-needle sock machine, the upper guide surface of the guide rhombus is horizontally set, and the rear needle foot of the guide needle plate can be moved along the upper guide surface.

[0009] The upper guide surface is horizontal. After the rear pin is moved to the upper guide surface, it can move along the guide surface. The upper guide surface supports and guides the rear pin.

[0010] In the aforementioned guide rhombus of the upper housing of a double-needle sock machine, the arc-shaped guide surface forms a natural and continuous arc transition at the boundary of the upper guide surface, and this arc transition is the peak point of the arc-shaped guide surface.

[0011] The arc transition eliminates abrupt acceleration changes, ensuring that the rear pin of the guide pin can be smoothly moved onto the upper guide surface.

[0012] In the aforementioned guide rhombus of the upper housing of a double-needle sock machine, the guide rhombus and the upper needle cylinder seat are detachably connected by fixing bolts.

[0013] The guide rhombus and the upper syringe holder are detachably connected by fixing bolts, making disassembly and assembly convenient and easy to maintain.

[0014] In the aforementioned guide rhombus of the upper housing of a double-needle sock machine, a rhombus positioning structure is also provided between the guide rhombus and the inner wall of the upper needle cylinder seat.

[0015] The diamond-shaped positioning structure can quickly position the guide diamond, enabling rapid assembly and disassembly, reducing maintenance and calibration time, and controlling the radial installation position of the guide diamond.

[0016] In the aforementioned guide rhombus of the upper housing of a double-needle sock machine, the rhombus positioning structure includes positioning grooves distributed circumferentially along the inner wall, and the rear end of the guide rhombus is provided with an arc-shaped positioning block adapted to the positioning grooves.

[0017] The arc-shaped positioning block at the rear end of the guide rhombus can be inserted into the positioning groove to achieve quick positioning, which can effectively improve the efficiency of disassembly and assembly. The radial installation position of the guide rhombus can be controlled by the cooperation between the arc-shaped positioning block and the positioning groove.

[0018] In the aforementioned double-needle sock machine upper housing guide rhombus, the guide rhombus is provided with a plurality of rhombus bolt holes, the rhombus bolt holes are located above the arc-shaped positioning block and the rhombus bolt holes partially penetrate the arc-shaped positioning block, the inner wall is provided with inner wall bolt holes adapted to the rhombus bolt holes, and fixing bolts are inserted in the rhombus bolt holes and the inner wall bolt holes.

[0019] The guide rhombus is securely fixed to the inner wall by fixing bolts that pass through the bolt holes in the rhombus and the bolt holes in the inner wall.

[0020] In the aforementioned double-needle sock machine upper housing guide rhombus, a drainage gap is left below the guide rhombus between the density rhombus and the inner wall.

[0021] The guide rhombus is positioned between the density rhombus and the inner wall to leave a drainage gap, which facilitates the discharge of foreign objects and effectively improves the discharge efficiency of impurities.

[0022] In the aforementioned double-needle sock machine upper housing guide rhombus, the density rhombus is provided with a guide notch that can cooperate with the front needle of the guide needle plate.

[0023] The lead pin of the guide pin is guided by the guide notch on the density diamond.

[0024] Compared with existing technologies, the advantages of this invention are as follows: 1. The rear pin of the guide pin is guided by the arc-shaped guide surface and enters the upper guide surface of the guide rhombus. The upper guide surface provides rear-end support for the guide pin. Compared with the traditional front-end support, the rear-end support utilizes gravity-assisted guidance, enabling the rear pin of the guide pin to obtain stable support in the initial stage of movement, resulting in better stability of the guide pin's displacement. 2. When the rear pin moves along the arc-shaped guide surface, it achieves surface contact guidance with the arc-shaped guide surface, which can significantly improve the uniformity of force distribution. The contact points are evenly distributed along the tangent direction of the arc, which can eliminate local stress concentration and ensure that the rear pin has no impact vibration during displacement, thus ensuring the stability and accuracy of the guide pin.

[0028] In this invention, when the upper syringe holder 1 rotates around the rotation axis, the rear needle pin of the guide needle plate can be moved from the end of the guide rhombus 3 to the upper guide surface 5 of the guide rhombus 3 through the needle pin guide structure 4 at the end of the guide rhombus 3, and move along the guide surface 5.

[0031] The rear pin is guided by the arc-shaped guide surface 7 and enters the upper guide surface 5 of the guide rhombus 3. When the rear pin moves along the arc-shaped guide surface 7, it achieves surface contact guidance between the rear pin and the arc-shaped guide surface 7, which can significantly improve the uniformity of force. The contact points are evenly distributed along the tangent of the arc, which can eliminate local stress concentration and ensure that there is no impact vibration during the displacement of the rear pin, so as to ensure the stability and accuracy of the guide pin.

[0032] The upper guide surface 5 is horizontal. After the rear pin is moved to the upper guide surface 5, it can move along the guide of the upper guide surface 5. The upper guide surface 5 plays a supporting and guiding role for the rear pin.

[0033] Specifically, combining Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the arc-shaped guide surface 7 forms a natural and continuous arc transition 8 at the boundary of the upper guide surface 5, and the arc transition 8 is the peak point of the arc-shaped guide surface 7.

[0034] The arc-shaped guide surface 7 forms a natural and continuous arc transition 8 at the boundary of the upper guide surface 5. The arc transition 8 can eliminate acceleration abrupt changes to ensure that the rear pin of the guide pin can be smoothly moved onto the upper guide surface 5.

[0035] Specifically, combining Figures 2-6 As shown, the guide rhombus 3 and the upper syringe seat 1 are detachably connected by fixing bolts.

The radial installation position of the guide rhombus 3 can be controlled by the cooperation of the arc-shaped positioning block 12 and the positioning groove 11. The guide rhombus 3 and the upper syringe seat 1 are detachably connected by fixing bolts, which is convenient for disassembly and assembly and easy for maintenance.

[0037] Specifically, combining Figures 2-6 As shown, the guide rhombus 3 is provided with several rhombus bolt holes 13. The rhombus bolt holes 13 are located above the arc-shaped positioning block 12 and the rhombus bolt holes 13 are partially inserted through the arc-shaped positioning block 12.
