Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machines, in particular to a warp beam bearing locking device for warp knitting machines. Background Art

[0002] A warp knitting machine is a machine used to produce woven items. The yarn is transported to the loop forming system for weaving through the rotation of the warp beam disc head. During the weaving process, one end of the warp beam is driven by a motor, and the other end cooperates with the bearing. The rotation of the ball inside the bearing makes the warp beam transmission smooth.

[0003] Since the warp axis assembly needs to be replaced frequently, a semicircular groove assembly structure is usually used to mount the warp axis bearing in the groove, and the warp axis bearing is prevented from falling out of the groove by the deadweight of the warp axis assembly. In order to prevent the warp axis bearing from falling out of the groove due to excessive rotation of the warp axis disk, a locking device is usually used in the related technology to limit the bearing, and the upper part of the safety clip is used to form a limiting effect on the upper end surface of the bearing, and the degree of tightening between the upper part of the safety clip and the bearing is controlled by adjusting the waist-shaped hole at the bottom of the safety clip. During the rotation of the handle, a preload is formed between the screw in the control handle and the bearing seat.

[0004] Although the above-mentioned locking device can ensure that the bearing will not jump out of the groove, in actual use, since the safety clip is fixed to the base through the waist-shaped hole, as the warp shaft disc head rotates and forms an interaction force with the safety clip, after long-term use, the connection between the safety clip, the base and the handle becomes unstable, and the safety clip has a tendency to rotate and deviate toward both sides under the action of its own gravity, so that the safety clip releases the restrictive effect on the upper end face of the bearing, and it is difficult to ensure the safety and stability of use during work.

[0005] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes the prior art known to those skilled in the art.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figures 1 to 6 The warp beam bearing locking device for a warp knitting machine shown in the figure comprises: a base 10, a safety clip 20 and an adjusting handle 30. The top of the base 10 has a semicircular groove 11, the bearing 1 is assembled in the semicircular groove 11, and the outer shaft surface is protruding from the top surface of the base 10. Both ends of the safety clip 20 are bent, and one end of the safety clip 20 forms a contact and extrusion effect with the outer shaft surface of the bearing 1, and the other end is connected to the base 10 through the adjusting handle 30.

[0031] Among them, an auxiliary block 21 and a guide groove 12 are respectively provided on the safety clip 20 and the base 10. The auxiliary block 21 is arranged at the end of the safety clip 20 away from the bearing 1, and is located on the side of the safety clip 20 facing the base 10. The guide groove 12 is arranged along the vertical direction of the base 10. The auxiliary block 21 is slidably connected to the guide groove 12, and the two sides of the guide groove 12 are fitted with the two sides of the auxiliary block 21.

[0032] The utility model respectively arranges an auxiliary block 21 and a guide groove 12 on the safety clip 20 and the base 10. After assembly, the two sides of the guide groove 12 form a restriction effect on the two sides of the auxiliary block 21, thereby ensuring that when the safety clip 20 is loose, it can only move in the vertical direction along the guide groove 12 under the action of its own gravity, avoiding rotation and deviation toward both sides, ensuring that the end of the safety clip 20 always forms a restriction effect on the bearing 1, thereby greatly improving the connection stability between the safety clip 20 and the base 10 and the bearing 1 and the safety of use.

[0033] It should be noted that the depth of the guide groove 12 may be greater than the thickness of the auxiliary block 21 , which is not specifically limited here, as long as it can ensure the limiting effect on the auxiliary block 21 and the supporting performance of the base 10 .

[0034] On the basis of the above embodiment, the safety clip 20 includes a limiting section 22, an intermediate section 23 and a connecting section 24. The intermediate section 23 is located between the limiting section 22 and the connecting section 24, and the limiting section 22 and the intermediate section 23 are arranged perpendicular to each other, and a space for a built-in warp shaft head is formed between the limiting section 22 and the intermediate section 23, thereby preventing the safety clip 20 from interfering with the shaft head during the rotation of the warp shaft, thereby ensuring the stability of the work; the connecting section 24 and the intermediate section 23 are arranged parallel to each other, and the auxiliary block 21 is arranged at one end of the connecting section 24 away from the intermediate section 23, and is located on the side facing the limiting section 22, thereby ensuring that the side of the connecting section 24 is in a completely fitted state when the connecting section 24 is connected to the base 10, thereby ensuring the stability of the connection.

[0035] On the basis of the above-mentioned embodiment, a transition section 25 is arranged between the limiting section 22, the middle section 23 and the connecting section 24, and the transition section 25 is an arc-shaped structure; the arc-shaped transition section 25 design can provide a more uniform stress distribution and reduce stress concentration, thereby improving the overall structural strength of the safety clip 20, reducing the risk of breakage or deformation due to long-term use or external force, and the overall lines are smoother, thereby improving the visual effect of the entire locking device.

[0036] On the basis of the above embodiment, a through waist-shaped hole 241 is provided at one end of the connecting section 24 close to the transition section 25. The waist-shaped hole 241 is arranged along the vertical direction. The adjusting handle 30 passes through the waist-shaped hole 241 and is connected to the base 10. By changing the relative position of the adjusting handle 30 and the waist-shaped hole 241, the degree of tightening between the safety clip 20 and the bearing 1 can be precisely controlled. The operation is simple and convenient, the flexibility is high, and it can adapt to different working conditions and requirements.

[0037] On the basis of the above embodiment, an assembly hole 13 is provided on the base 10, the assembly hole 13 is arranged opposite to the waist-shaped hole 241, and a threaded structure is provided on the inner axial surface; through the connection relationship of the threaded structure, the stability of the assembly of the safety clip 20 is ensured, and the resistance of the adjustment handle 30 to the force of the connection of the safety clip 20 during operation is further improved, and the adjustment handle 30 is effectively prevented from loosening during operation.

[0038] On the basis of the above embodiment, the adjustment handle 30 includes a handle 31 and a screw 32. The handle 31 includes a first section 311 and a second section 312. The first section 311 is threadedly connected to the outer axial surface of the screw 32. The second section 312 is hollow inside to form a receiving cavity 312a. One end of the screw 32 is arranged in the receiving cavity 312a, and the other end passes through the safety clip 20 and is threadedly connected to the base 10. The second section 312 forms a stopper 312b at one end facing the first section 311, and the outer side surface of the stopper 312b is abutted against the end surface of the first section 311. The screw 32 is provided with a plurality of holes 314a and a plurality of holes 314b. An elastic member 313 is sleeved on the outer axial surface of the nail 32, and the elastic member 313 is pressed and arranged in the accommodating cavity 312a, and its two ends are respectively abutted against the inner side surfaces of the screw 32 and the stopper 312b; through the threaded connection between the second section 312 and the screw 32 and the limiting effect of the first section 311 on the end of the screw 32 in the accommodating cavity 312a, the stability of the connection between the two is guaranteed. At the same time, the setting of the stopper 312b prevents the screw 32 from slipping out of the accommodating cavity 312a, thereby improving the safety of the structure. The tightening state of the screw 32 can be controlled by turning the handle 31, which is simple and convenient.

[0039] Based on the above embodiment, a gripping portion 314 is fixedly connected to one side of the outer axial surface of the second section 312, and the gripping portion 314 is in the shape of an elongated strip. The design of the gripping portion 314 enables the operator to rotate the adjustment handle 30 more easily, thereby reducing hand discomfort and improving the convenience of operation.

[0040] On the basis of the above embodiment, a lead-out hole 312c is provided on the end surface of the second section 312 facing away from the first section 311, and a pressing portion 321 is provided on the end surface of the screw 32 facing away from the base 10, and the pressing portion 321 protrudes through the lead-out hole 312c and is provided on the end surface of the second section 312; an inner tooth ring and an outer tooth ring are respectively provided on the inner side surface of the accommodating cavity 312a and the outer axial surface of the end of the screw 32, and the inner tooth ring and the outer tooth ring are in a separated state or a meshed state.

[0041] When in use, by pressing the pressing portion 321, under the restriction of the threaded connection between the first sub-portion 311 and the outer side of the screw 32, the elastic member 313 is further compressed by the force, and the second sub-portion 312 is forced to move outward, so that the inner tooth ring on the inner side of the accommodating cavity 312a and the outer tooth ring on the outer axial surface of the end of the screw 32 are in a meshing state, and then when the second sub-portion 312 is rotated by the gripping portion 314, the screw 32 can be controlled to rotate synchronously, thereby controlling the screw 32 to be fixed to the assembly hole 10 on the base 10. 3. When loosened, the safety clip 20 is in a free state, and the relative position between the safety clip 20 and the base 10 can be changed, so as to realize the replacement of the bearing 1. When tightened, it can ensure that the safety clip 20 and the base 10 are in a stable connection state, thereby ensuring the safety of the use process. At the same time, the way in which the second section 312 is moved out and then rotated also avoids the interference between the gripping portion 314 and the middle section 23 of the upper safety clip 20 during the rotation process, thereby ensuring that the rotation of the screw 32 can be smoothly realized.

[0042] On the basis of the above embodiment, a pair of reinforcing ribs 14 are fixedly arranged on the base 10. The two reinforcing ribs 14 are symmetrically arranged along the vertical direction and are located on the side where the safety clip 20 is located, thereby increasing the overall rigidity and strength of the base 10, making it less likely to be deformed or damaged when subjected to external force, and making it have a stronger load-bearing capacity, thereby ensuring that a stable and reliable locking effect can be provided under various working conditions.

[0043] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
