Description

Technical Field

[0001] The invention relates to the field of textile machinery flat knitting machines, and in particular to a smart running machine. Background Art

[0002] In the flat knitting machine, the Zhipao machine is set above the needle bed. The Zhipao machine completes the task of feeding various yarns into the lower needle bed, and the needle bed is used for yarn weaving.

[0003] The intelligent running machine includes several groups of yarn mouth transmission components. Each group of yarn mouth components includes a guide rail, a yarn mouth seat, and a yarn mouth. The yarn mouth is installed on the yarn mouth seat, and the yarn mouth seat is installed on the guide rail; the yarn mouth seat is driven to move by a belt, and the belt is driven by a motor to complete the yarn feeding function.

[0004] In the existing flat knitting machine technology, the belt tension is adjusted by adjusting the distance between the two pulleys. One pulley is mounted on the motor output shaft, and the other pulley is mounted on the pulley fixing adjustment device. The position of the pulley fixing adjustment device is adjustable. For example, in the patent with patent number CN2019200399486, the pulley fixing adjustment device includes a base and a pulley seat. The pulley is installed in the pulley seat. By adjusting the position of the pulley seat, the pulley tension is adjusted. Therefore, the belt mounting frame needs to realize the above functions, and its structure is relatively complex and the volume is relatively large.

[0005] In the existing flat knitting machine technology, the yarn mouth seat moves on the guide rail, and excessive friction will affect the operation of the yarn mouth seat. Therefore, relevant technical personnel have improved the assembly method of the yarn mouth seat and the guide rail, such as the yarn mouth transmission system of a computer flat knitting machine with patent number CN2021205528866, in which the yarn mouth seat is assembled with the guide rail by means of rollers, thereby reducing friction. In the connection structure between this yarn mouth seat and the roller, the positions of the upper and lower rows of roller groups are fixed, and the distance between the two is fixed. Therefore, guide rails of corresponding sizes must be selected for assembly, and in order to ensure the smooth operation of the rollers, the dimensional accuracy and assembly accuracy of the rollers, the dimensional accuracy of the guide rails, and the assembly accuracy of the guide rails and rollers must be highly guaranteed, and the overall production cost is high. Moreover, after long-term use, the surface of the roller or the guide rail will wear and the size will change. The roller may not run smoothly and may even slide out of the guide rail and fail to complete the production function. At this time, the corresponding accessories need to be replaced, increasing the subsequent maintenance cost.

[0006] In view of the above problems, the present invention designs a smart running device, and this case is thus generated. Summary of the invention

[0007] The present invention provides a smart running device, which has the characteristics of simple structure, quick assembly and low cost; specifically, the present invention is implemented through the following technical solutions:

[0020] The plurality of second belt pulleys in the same group of yarn mouth transmission components are sleeved together on the same shaft from top to bottom, thus saving the installation space of the second belt pulleys, and utilizing the retaining ring to separate two adjacent second belt pulleys to avoid affecting the operation of the two belt pulleys.

[0021] Furthermore, grooves are respectively provided on the upper and lower end surfaces of the guide rail, the side walls on both sides of the groove form an obtuse angle with the groove bottom, and the spacing between the two side walls of the groove bottom is smaller than the spacing between the two side walls of the notch; the yarn mouth seat is assembled on the side of the guide rail.

[0022] Furthermore, the yarn mouth seat comprises a yarn mouth seat body, and on the A side of the yarn mouth seat body, two rows of roller groups are installed in sequence from top to bottom, and a plurality of rollers are horizontally arranged in each row of roller groups.

[0023] The upper and lower rows of roller assemblies can clamp the guide rail.

[0024] Furthermore, a groove is arranged on the roller, the groove surrounds the circumference of the roller, the groove is a V-shaped groove, and a groove wall on one side of the V-shaped groove is parallel to the end face of the roller.

[0025] Furthermore, a base is derived outward from the side of the yarn mouth seat body, a groove is arranged on the lower end face of the base, a through hole is opened on the top end face of the base, and the through hole is connected to the bottom of the groove; a top block is assembled in the groove of the base, and a screw hole is opened on the top end of the top block; the screw is assembled in the through hole of the base, and the lower end of the screw is threadedly assembled with the screw hole of the top block; a transverse through hole is arranged in the top block, and a leaf spring is passed through the through hole, and both ends of the leaf spring extend out of the top block, and the end of the leaf spring is connected to the roller bracket; the middle part of the roller bracket is hinged to the yarn mouth seat body, one end of the roller bracket is assembled and connected with the roller in one row of roller groups, and the other end of the roller bracket is connected to the end of the leaf spring.

DETAILED DESCRIPTION

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0053] like Figure 1 , Figure 2 As shown, a smart treadmill comprises a bracket and a plurality of yarn mouth transmission components arranged on the bracket; the bracket comprises two bracket seats 1 arranged on both sides; a group of yarn mouth transmission components comprises a linear guide rail 2, a yarn mouth seat 3, a belt 4, a motor 5 and a pulley 6; the linear guide rail 2 is erected between the two bracket seats 1; a plurality of yarn mouth seats 3 are mounted on the linear guide rail 2, and the yarn mouth seats 3 are fixedly assembled with the yarn mouths; each yarn mouth seat 3 is respectively connected with a belt 4; each belt 4 is mounted on two pulleys 6, and the two pulleys 6 are respectively arranged on the bracket seats 1 on both sides, and one of the pulleys 6 is linked to a motor 5; each yarn mouth seat 3 is controlled by its own motor 5 and operates independently, the motor 5 outputs torque, drives the pulley 6 to rotate, drives the belt 4 to transport and operate, and the belt 4 drives the yarn mouth seat 3 to operate on the linear guide rail 2.

[0054] The assembled belt 4 is in a closed loop, and the endless belt 4 is arranged around the guide rail 2. If the diameter of the pulley 6 is too small, the distance between the two sides of the endless belt 4 is too small, and there will be a phenomenon that one side of the belt 4 is close to the guide rail 2, which will cause the belt 4 to run poorly; Figure 3 As shown, a belt expander 8 is also provided on the bracket seat 1 of the motor 5. The belt expander 8 is assembled in the loop of the endless belt 4. The belt expander 8 is used to increase the spacing between the belts 4 on both sides of the guide rail 2, thereby increasing the distance between the single-sided belt 4 and the guide rail 2, so that the single-sided belt 4 is away from the guide rail 2, avoiding friction between the moving belt 4 and the guide rail 2.

[0055] 1. Band expander 8.

[0056] like Figure 4As shown, the belt expander 8 includes a belt expander wheel 81, which is assembled on a shaft 82, and the shaft 82 is connected to a base 83. When in use, the belt expander wheel 81 is installed between the belts 4 on both sides of the guide rail 2, and the position of the belt expander wheel 81 is adjusted so that the belt expander wheel 81 is close to the single-sided belt 4. The original running trajectory of the single-sided belt 4 is a straight line. After the belt expander wheel 81 is installed, the running trajectory of the single-sided belt 4 is a broken line.

[0057] The number of the expansion pulleys 81 installed between the belts 4 on both sides of the guide rail 2 can be one or two.

[0058] like Figure 4 , Figure 5 As shown, when there are two expansion pulleys 81, the belts 4 on both sides of the guide rail 2 are spread apart by the two expansion pulleys 81, and the single-side belt 4 is fitted with one expansion pulley 81. The two expansion pulleys 81 are respectively mounted on two shafts 82, the distance between the two shafts 82 is L1, the outer diameter of the expansion pulley 81 is D1, and the outer diameter of the pulley 6 with the smallest outer diameter among the two pulleys 6 is D2, then L1+D1>D2. The two expansion pulleys 81 move independently and do not interfere with each other.

[0059] The base 83 includes an upper and lower bottom plate 831, which are connected by a connecting column 832. The connecting column 832 and the bottom plate 831 are an integral structure or a split structure. An axial hole is provided on the bottom plate 831 for assembling the shaft 82. The bottom plate 831 is a quadrilateral, and the connecting column 832 is arranged at two diagonal points, and the axial hole is provided at the other two diagonal points.

[0060] like Figure 6 , Figure 7 , Figure 8 As shown, when there is only one expanding pulley 81, the belts 4 on both sides of the guide rail 2 are stretched by the same expanding pulley 81, and the outer diameter of the expanding pulley 81 is larger than the outer diameter of the pulley 6 with the smallest outer diameter among the two pulleys 6. The single expanding pulley 81 can fit the belts 4 on both sides respectively.

[0061] like Figure 5 , Figure 7 As shown, since a plurality of yarn mouth seats 3 are arranged on a guide rail 2 and driven by a plurality of belts 4, a plurality of belt expansion pulleys 81 are required accordingly. The plurality of belt expansion pulleys 81 are sleeved on the same shaft 82, and a gasket 84 is arranged between two adjacent pulleys 6 on the same shaft 82. The gasket 84 is used to separate the belt expansion pulleys 81 to maintain the spacing between the belt expansion pulleys 81.

[0062] like Figure 1As shown, in each group of yarn mouth transmission components, a plurality of yarn mouth seats 3 are arranged on a track, and a plurality of belts 4 and motors 5 are arranged correspondingly, and a plurality of pulleys 6 are arranged on the bracket seats 1 on both sides. In order not to affect the operation of each belt 4, the height position of the belt 4 connected to each yarn mouth seat 3 is different, so that the plurality of belts 4 are arranged in sequence from top to bottom, and the corresponding plurality of pulleys 6 arranged on the same bracket seat 1 are also at different heights, and the plurality of pulleys 6 are arranged in sequence from top to bottom.

[0063] 2. Motor base 51, pulley 6.

[0064] The specific belt 4 height setting method is as follows:

[0065] like Fig. 9 , Fig.10 As shown, the motor 5 is installed on the motor seat 51, and the motor seat 51 is arranged on the bracket seat 1; the motor seat 51 is a stepped type, and multiple layers of platforms with different heights are arranged in the motor seat 51, and a motor 5 is placed on each platform; a pulley 6 is mounted on the output shaft of the motor 5, and since the motors 5 are at different heights, the pulleys 6 connected to the motors 5 are at different heights; as shown in FIG. Fig.11 , Fig.12 As shown, a plurality of pulleys 6 arranged on another support seat 1 are assembled on the pulley frame in layers from top to bottom; the pulley frame is composed of a base 63 and a shaft 61 vertically arranged on the base 63, the base 63 is fixed to the support seat 1, and a plurality of pulleys 6 are assembled on the shaft 61 in sequence from top to bottom, and a bearing is assembled between the pulley 6 and the shaft 61, and the bearing is fixed on the shaft by a retaining ring 62, so as to ensure the spacing between adjacent pulleys 6. Each belt 4 is assembled on the pulleys 6 at different heights, so that each belt 4 is at a different height.

[0066] 3. Linear guide 2.

[0067] like Fig.13 As shown, grooves 21 are respectively provided on the upper and lower end surfaces of the guide rail 2, and the side walls on both sides of the groove 21 form an obtuse angle with the groove bottom of the groove 21, and the spacing between the two side walls of the groove bottom is smaller than the spacing between the two side walls of the notch, so that the groove 21 presents an outward expansion shape. The obtuse angles between the side walls on both sides of the groove 21 and the groove bottom of the groove 21 range from 110 degrees to 170 degrees.

[0068] The yarn mouth seat 3 is mounted on the side of the guide rail 2 and is clamped on the groove wall of the groove 21 of the guide rail 2, so the yarn mouth seat 3 can be mounted on both sides of the guide rail 2.

[0071] A groove 321 is provided on the roller 32, and the groove 321 surrounds the circumference of the roller 32. The groove 321 is a V-shaped groove, and one side wall of the V-shaped groove is parallel to the end face of the roller 32; when the roller 32 is assembled on the guide rail 2, the groove 321 of the roller 32 is stuck on the side wall of the groove 21 of the guide rail 2.

[0072] By means of the roller 32, the contact mode between the yarn mouth seat 3 and the guide rail 2 is changed from the previous sliding friction to rolling friction, thereby reducing the friction force and making the yarn mouth seat 3 move more smoothly.

[0073] The spacing between the upward roller group and the downward roller group can be adjusted according to the actual height of the guide rail 2, so as to ensure that the pressure exerted by the roller 32 on the guide rail 2 is within an appropriate range, and the roller 32 will not fall off the guide rail 2 while ensuring smooth operation; the specific adjustment method is as follows:

[0074] like Fig.14 As shown, the position of the roller 32 in the downstream roller group installed on the yarn mouth seat body 31 is fixed: a hole for assembling the roller 32 is opened at the lower part of the side of the yarn mouth seat body 31, and the roller 32 is assembled in the roller 32 hole of the yarn mouth seat body 31 through the transmission shaft, and the roller 32 can rotate around the axis.

[0075] like Fig.14 , 15As shown, the roller 32 in the upward roller group can move up and down relative to the yarn mouth seat body 31: a base 311 is derived outward from the side of the yarn mouth seat body 31, and a groove 3112 is set on the lower end surface of the base 311.

[0083] like Fig.18 As shown, a U-shaped groove is provided on the end of the clamping member 91 for mortise and tenon connection, and an inclined convex strip 915 is provided on the top of the U-shaped groove, or an inclined dovetail groove is provided on the end of the clamping member 91 for mortise and tenon connection; an inclined slide groove 921 is provided on the end of the fixing member 92 for mortise and tenon connection, and an angle H is formed between the inclined slide groove 921 and the G straight line, and the angle of the angle H is between 20 and 70 degrees; when the clamping member 91 and the fixing member 92 are connected, the inclined convex strip 915 is gradually inserted into the inclined slide groove 921 along the inclined slide groove 921, and as the inclined convex strip 915 is gradually inserted into the inclined slide groove 921, the depth of the clamping member 91 inserted into the fixing member 92 in the direction perpendicular to the G straight line gradually increases, and the overlapping connection length of the clamping member 91 and the fixing member 92 in the G straight line direction gradually increases, and the overall length of the belt connecting device 9 gradually decreases.

[0084] like Fig. 22 As shown, the inclined slide groove 921 forms an angle H with the straight line G, the length of the clamping member 91 is L1, the length of the fixing member 92 is L2, the depth of the fixing member 92 inserted into the clamping member 91 is S, and the overall length of the belt connecting device 9 is L, the following formula can be obtained:

[0085] L=2*L1+L2-S / tan(H).

[0086] The fixing member 92 is fixed to the yarn mouth seat 3 by a third screw 922. Fig.19 As shown; if the tightness of the belt 4 needs to be adjusted during use, first loosen the second screw 916 to make the clamping member 91 active, and then turn the third screw 922 on the fixing member 92 forwards and backwards to move the fixing member 92 in a direction perpendicular to the G straight line, thereby changing the insertion depth S of the clamping member 91 and the fixing member 92. The clamping member 91 moves on the G straight line, further changing the overlapping connection length (S / tan(H)) between the clamping member 91 and the fixing member 92 in the G straight line direction, thereby finally achieving the tightening or loosening of the belt 4. After the adjustment is completed, tighten the second screw 916.

[0087] In the unadjusted state, the belt connecting device 9 is as follows Fig.19 shown.

[0088] When the third screw 922 is tightened, the clamping member 91 can be moved on the straight line G, so that the overlapping connection length (S / tan(H)) of the clamping member 91 and the fixing member 92 increases, and the overall length of the belt connecting device 9 gradually decreases. Fig. 20 As shown, the belt 4 is tightened at this time;

[0089] When the third screw 922 is loosened, the clamping member 91 can be moved on the straight line G, so that the overlapping connection length (S / tan(H)) of the clamping member 91 and the fixing member 92 is reduced, and the overall length L of the belt connecting device 9 is gradually increased. Fig.21 As shown, the belt 4 is loosened at this time.

[0090] During the tension adjustment process, on the G straight line, the clamping member 91 will be displaced relative to the yarn mouth seat 3, and the second screw 916 is fixed to the horizontal position of the yarn mouth seat, so the second screw hole in the clamping member 91 where the second screw 916 is assembled is a strip hole, such as Fig.18 As shown, it is convenient for the second screw 916 to move in the clamping member 91 .

[0091] The above are preferred implementations of the present invention. Several other simple substitutions and modifications made under the premise of the concept of the present invention should be regarded as belonging to the protection scope of the present invention.
