Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a shock-resistant knitting machine heart. Background Art

[0002] The large circular knitting machine is a commonly used textile machinery. Its core component is the weaving mechanism, which mainly includes parts such as the needle cylinder, the fixed seat and the triangular saddle. During the use of the knitting machine, the triangular saddle of the knitting machine may become loose due to the high-speed operation of the knitting machine, thus affecting the working efficiency of the knitting machine.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN214529503U discloses a high-precision earthquake-resistant knitting machine heart, including a fixed seat, a pad is fixedly connected to the inner side of the top of the fixed seat, three brackets are fixedly connected to the outer side of the pad and located at the top of the fixed seat, a triangle seat group is fixedly installed on the top of the pad, the triangle seat group includes a plurality of saddles, a plurality of saddles are spliced ​​into a ring structure, and any two adjacent saddles are mutually clamped, the saddle includes a bottom plate, a clamping strip and a clamping groove are respectively fixedly connected on the two side walls of the bottom plate, a limiting groove is opened on the top of the bottom plate, and a mounting block is connected in the limiting groove and located at the top of the bottom plate, and the utility model relates to the technical field of knitting machines. The high-precision earthquake-resistant knitting machine heart replaces the traditional plurality of triangle seats with a rectangular bottom structure with a triangle seat group that can be spliced ​​into a ring structure, thereby avoiding the saddle displacement caused by the vibration of the knitting machine and improving the processing accuracy.

[0004] The above mechanism avoids the saddle displacement caused by the vibration of the knitting machine by replacing the traditional triangular seat with a triangular seat group with a ring structure. However, in actual use, after changing to a triangular seat group with ring-shaped splicing, once one of the triangular seats becomes loose, the entire triangular seat group will become loose and unable to achieve stable operation. At the same time, in the case of frequent vibrations, it is difficult to achieve its own seismic resistance by relying on the snap fit. Utility Model Content

[0005] The utility model aims to provide a shock-resistant knitting machine heart to solve the problem in the background art that loosening of one of the cam joints will cause the entire cam assembly to loosen and the shock-resistant performance to be weak.

[0006] To achieve the above object, the utility model provides the following technical solutions: a shock-resistant knitting machine core, comprising a fixed bottom plate and a saddle installed at equal intervals on the top of the fixed bottom plate, one side of the saddle is connected with a triangular seat group, and one end of the triangular seat group is provided with a thread hole;

[0007] The top end of the saddle is threadedly connected with a first bolt, and both ends of the first bolt are provided with a pressing and shockproof mechanism for limiting the first bolt, and the pressing and shockproof mechanism includes a fixing frame, and the fixing frame is fixedly connected to both ends of the top end of the saddle, and a pressing plate is slidably connected inside the fixing frame;

[0008] One side of the saddle is fixedly connected with a limiting block, and both ends of the triangular seat group are provided with limiting mechanisms for locking and connecting the saddle and the triangular seat group.

[0009] Furthermore, an airbag is fixedly connected to the top of the saddle at the bottom end of the first bolt, and an anti-skid plate is fixedly connected to the top of the airbag.

[0010] Furthermore, the top end of the anti-skid plate fits with the bottom end of the first bolt, and the anti-skid plate is arranged above the saddle.

[0011] Furthermore, both ends of the bottom end of the anti-slip plate are fixedly connected with air bags, and an elastic mechanism is formed between the air bags and the connecting springs.

[0012] Furthermore, one side of the fixing frame is connected to one side of the airbag via a hose, and the cross section of the fixing frame is in an inverted "L" shape.

[0013] Furthermore, the limiting mechanism includes a limiting groove, and a limiting groove matching the limiting block is opened on one side of the triangular seat group, both ends of the triangular seat group are threadedly connected with a second bolt, and one end of the triangular seat group is opened with a threaded groove matching the second bolt.

[0014] Furthermore, one end of the second bolt passes through the triangular seat assembly and the limiting groove and extends to the other end of the triangular seat assembly, and the thread grooves are evenly spaced and distributed at one end of the triangular seat assembly:

[0015] 1. The first bolt passes through the bottom of the saddle and is threadedly connected between the fixed bottom plate, so that the position of the saddle is fixed. When the first bolt is pressed downward, the two sides of the bottom end of the first bolt press the anti-slip plate, so that the air bag under the anti-slip plate discharges the internal gas and transports it to the inside of the fixing frame, so that the pressing plate inside the fixing frame is pushed out. The pressing plate limits the height of the first bolt, so that the seismic resistance of the first bolt is increased, and loosening is effectively avoided;

[0016] Furthermore, the fixing frame and the pressing plate are slidably connected by a piston, and the piston can ensure the airtightness inside the fixing frame, and at the same time, the bottom end of the pressing plate can contact the top end of the first bolt, so that the top end of the first bolt is limited, thereby effectively increasing the stability of the first bolt;

[0017] Furthermore, when the first bolt is pressed downward, the bottom end of the first bolt contacts the top end of the anti-slide plate. After the first bolt contacts the anti-slide plate, the friction force increases, thereby reducing the angle deflection and position displacement of the first bolt caused by the working vibration of the knitting machine.

[0018] 2. The position of the saddle is fixed by rotating the first bolt through the saddle, and then the triangle seat assembly is passed through the limit block, so that the limit block and the limit groove are engaged with each other, thereby basically fixing the position of the triangle seat assembly, and then the second bolt is passed through the triangle seat assembly and the limit block, so that the second bolt and the thread groove are threadedly connected, and the position of the saddle and the triangle seat assembly is fixed from different directions, thereby achieving a stable connection between the saddle and the triangle seat assembly, effectively avoiding the loosening of the saddle and the triangle seat assembly during high-speed vibration, and increasing the overall shock resistance during use;

[0019] Furthermore, the mutual engagement between the limit block and the limit groove can assist the saddle and the triangle seat assembly in performing basic position restrictions before locking using the second bolt and the threaded groove, making it convenient for the staff to replace or adjust the triangle seat assembly in time when the locking connection is not performed, thereby ensuring the overall stability during operation.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution shown is to solve the problem that the saddle 2 and the triangle seat group 3 are easily loosened and separated during the operation of the knitting machine: the anti-seismic knitting machine heart discloses a locking mechanism, including a fixed base plate 1 and a saddle 2 installed at equal intervals on the top of the fixed base plate 1, one side of the saddle 2 is snap-connected with the triangle seat group 3, and one end of the triangle seat group 3 is provided with a wire hole 5, one side of the saddle 2 is fixedly connected with a limiting block 6, and both ends of the triangle seat group 3 are provided with a limiting mechanism for locking the saddle 2 and the triangle seat group 3, the limiting mechanism includes a limiting groove 7, and one side of the triangle seat group 3 is provided with a limiting groove 7 matching the limiting block 6, both ends of the triangle seat group 3 are threadedly connected with a second bolt 8, and one end of the triangle seat group 3 is provided with a thread groove 9 matching the second bolt 8, one end of the second bolt 8 passes through the triangle seat group 3 and the limiting groove 7 and extends to the other end of the triangle seat group 3, and the thread grooves 9 are evenly distributed at one end of the triangle seat group 3.

[0031] In this example, the position of the saddle 2 is fixed by rotating the first bolt 4 through the saddle 2, and then the triangular seat group 3 is passed through the limit block 6, so that the limit block 6 and the limit groove 7 are engaged with each other, thereby basically fixing the position of the triangular seat group 3, and then the second bolt 8 is passed through the triangular seat group 3 and the limit block 6, so that the second bolt 8 and the thread groove 9 are threadedly connected, and the positions of the saddle 2 and the triangular seat group 3 are fixed from different directions, thereby achieving a stable connection between the saddle 2 and the triangular seat group 3, effectively avoiding the loosening of the saddle 2 and the triangular seat group 3 due to high-speed vibration, and increasing the overall shock resistance during use.

[0032] Embodiment 2:

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7The technical solution shown is to solve the problem of loose connection of the saddle 2 when the knitting machine is working: the anti-vibration heart of the knitting machine discloses a press-vibration-proof mechanism, the top end of the saddle 2 is threadedly connected with a first bolt 4, and both ends of the first bolt 4 are provided with a press-vibration-proof mechanism for limiting the first bolt 4, the press-vibration-proof mechanism includes a fixing frame 13, and the fixing frame 13 is fixedly connected to the two ends of the top end of the saddle 2, and the inside of the fixing frame 13 is slidably connected with a pressing plate 14, one side of the fixing frame 13 is connected to one side of the airbag 11 through a hose, and the cross-section of the fixing frame 13 is an inverted "L" shape.

[0034] In this example, the first bolt 4 passes through the bottom of the saddle 2 and is threadedly connected to the fixed base plate 1, so that the position of the saddle 2 is fixed. In the process of pressing the first bolt 4 downward, the two sides of the bottom end of the first bolt 4 press the anti-slip plate 10, so that the airbag 11 under the anti-slip plate 10 discharges the internal gas and transports it to the inside of the fixing frame 13, so that the pressing plate 14 inside the fixing frame 13 is pushed out. The fixing frame 13 and the pressing plate 14 are connected by a piston sliding connection. The piston can ensure the airtightness inside the fixing frame 13, and at the same time, the bottom end of the pressing plate 14 can contact with the top end of the first bolt 4, so that after the first bolt 4 moves downward to a certain depth, the height of the first bolt 4 is limited, thereby increasing the seismic resistance of the first bolt 4 and effectively avoiding loosening.

[0035] Embodiment three:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 The technical solution shown is based on the second embodiment, in order to solve the problem that the first bolt 4 may separate from the threads due to vibration during operation: the shock-resistant knitting machine heart discloses an anti-skid mechanism, and the top of the saddle 2 at the bottom end of the first bolt 4 is fixedly connected to an air bag 11, and the top of the air bag 11 is fixedly connected to an anti-skid plate 10, the top of the anti-skid plate 10 is fitted with the bottom end of the first bolt 4, and the anti-skid plate 10 is arranged above the saddle 2, both ends of the bottom end of the anti-skid plate 10 are fixedly connected to the air bag 11, and an elastic mechanism is formed between the air bag 11 and the connecting spring 12.

[0037] In this example, when the first bolt 4 is pressed downward, the bottom end of the first bolt 4 will contact the top end of the anti-slip plate 10. After the first bolt 4 and the anti-slip plate 10 come into contact, the friction force will increase, thereby reducing the angle deflection and position displacement of the first bolt 4 caused by the working vibration of the knitting machine.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
