Description

Technical Field

[0001] The invention relates to textile equipment, in particular to a mounting system for fixing a jacquard to a comb bar. Background Art

[0002] The existing jacquard is fixed to the comb bar by installing the jacquard needle plate with a jacquard fixing seat. The jacquard fixing seat is fixed to the rear end of the jacquard, and generally includes a fixing seat body, two screws, a slider and a spring sleeved on each screw. The fixing seat body is provided with two through holes for the screws to pass through and a slider groove. The slider is placed in the slider groove. The slider is provided with two threaded holes that cooperate with the two screws for the two screws to pass through. The slider is pressed against the spring sleeved on each screw. The jacquard can be fixed to the comb bar by tightening the two screws, and the jacquard can be removed from the comb bar by loosening the two screws. The disadvantage of this fixing method is that since the piezoelectric jacquard needs to be disassembled and assembled on the comb bar many times during the actual operation process, when the screws are loosened too little, the piezoelectric jacquard is not easy to be removed from the comb bar, and when the screws are loosened too much, the screws are easily separated from the slider, resulting in the loss of parts, especially during the operation of the machine, if the phenomenon of the screws loosening and falling occurs, it will cause serious potential accidents.

[0003] There is a need in the art for a mounting system that securely and reliably fixes the jacquard to a comb bar. Summary of the invention

[0004] The present invention aims to design a novel jacquard comb bar installation system, which can overcome the technical problems, especially the safety problems, existing in the prior art when the jacquard is installed on the comb bar and removed from the comb bar.

[0005] In one aspect, the present invention provides a jacquard comb bar installation system, including a jacquard, a jacquard fixing seat and a comb, the jacquard fixing seat is fixed on the jacquard, and the jacquard is fixed to the comb bar through the jacquard fixing seat, characterized in that the jacquard fixing seat includes a fixing seat body, a screw and a slider, the slider is provided with a threaded hole for the screw to pass through, the fixing seat body is provided with a slider groove and a through hole communicating with the slider groove, the screw passes through the through hole and the threaded hole and is connected to the slider, the tail of the screw abuts against the tail end of the needle plate of the jacquard, the slider groove is constructed to accommodate at least a portion of the slider and the slider cannot rotate around the central axis of the screw in the slider groove, but can only move axially along the central axis of the screw, the jacquard comb bar installation system also includes a screw blocking mechanism, the screw blocking mechanism can prevent the screw from making axial movement along its central axis, but does not affect the screw from making rotational movement around its central axis.

[0006] In one embodiment, the jacquard fixing seat is provided with two screws and two sliders, each slider is provided with a threaded hole for one screw to pass through, the fixing seat body is provided with two slider grooves separated from each other and through holes respectively communicating with the two slider grooves separated from each other, and the screw blocking mechanism is constructed as follows: the jacquard is provided with a cover shell, the rear end of the cover shell is provided with a clamping portion, the fixing seat body has a tail portion, the tail portion is provided with a clamping slot, and the clamping slot is constructed so that when the clamping portion is clamped into the clamping slot, the rear end of the cover shell can prevent the screw from making axial movement along its central axis, but does not affect the screw from making rotational movement around its central axis.

[0007] In a preferred embodiment, the rear end of the cover shell extends downward, and the rear end is also provided with a blocking portion for preventing the screw from making axial movement along its central axis.

[0008] Further preferably, a buckling portion is further provided on the cover shell, and a buckling groove cooperating with the buckling portion is provided on the needle plate.

[0009] In one embodiment, the screw blocking mechanism is a separate component fixedly connected to the tail of the jacquard mount.

[0010] In one embodiment, the jacquard mount is fixedly connected to the needle plate of the jacquard by means of additional screws.

[0011] The jacquard comb installation system of the present invention allows the operator to use an operating tool to rotate the head of the screw that cooperates with the slider, because the screw blocking mechanism prevents the screw from moving axially along its central axis, the slider groove prevents the slider from rotating around the central axis of the screw, but allows the slider to move axially along the central axis of the screw. Therefore, it is possible to achieve axial movement of the slider along the central axis of the screw without the screw moving axially, thereby locking the piezoelectric jacquard to the comb or loosening it from the comb through the slider. The technical solution of the present invention can omit the spring in the prior art, eliminate the interference of the spring, and ensure that the screw will not fall when the jacquard is disassembled, thereby avoiding safety hazards.

[0016] The present invention will be further described below in conjunction with the accompanying drawings. It should be clear that the specific embodiments of the present invention described in the accompanying drawings are only for illustrating the present invention, and are not strictly drawn according to actual sizes and proportions. Therefore, the drawings in the present invention should not be interpreted as any limitation to the present invention. The scope of protection of the present invention is defined by the claims.

[0017] For the sake of brevity, not all components or feature structures may be labeled in some drawings. Therefore, when reading the following description, all drawings should be referenced to each other for a clear and complete understanding of the present invention.

[0018] It should be understood that directional terms that may appear in the present invention, such as but not limited to "up", "down", "left", "right", "front", "back", "head", "tail", etc., are merely relative concepts and should not be interpreted as limiting the scope of the present invention.

[0019] See also Figure 1-Figure 4 The jacquard fixing seat, an important component of the jacquard comb bar installation system of the present invention, comprises a fixing seat body 90, two screws 951, 952 and two sliders 981, 982, the slider 981 is provided with a threaded hole 9811 for the screw 951 to pass through, and the slider 982 is provided with a threaded hole 9821 for the screw 952 to pass through (see Figure 3 The fixing seat body 90 is provided with two slider grooves 9061 and 9062 separated from each other and through holes 9021 and 9022 respectively communicating with the two slider grooves 9061 and 9062 separated from each other (see Figure 1 , Figure 2 ). The screw 951 passes through the through hole 9021 and the threaded hole 9811 to connect with the slider 981, and the screw 952 passes through the through hole 9022 and the threaded hole 9821 to connect with the slider 982. The tail 9511 of the screw 951 abuts against the tail end 101 of the jacquard needle plate 10, and the tail 9521 of the screw 952 also abuts against the tail end 101 of the jacquard needle plate 10 (see Figure 3 , Figure 4 ). The slider grooves 9061 and 9062 are respectively configured to accommodate a portion of the sliders 981 and 982, and the slider 981 cannot rotate around the central axis (not shown) of the screw 951 in the slider groove 9061, but can only move axially along the central axis of the screw 951. Similarly, the slider 982 cannot rotate around the central axis (not shown) of the screw 952 in the slider groove 9062, but can only move axially along the central axis of the screw 952.

[0020] like Figure 3 , Figure 4 As shown, the fixing seat body 90 is fixedly connected to the needle plate 10 by inserting two fixing screws (not shown) through the hole 9041 on the fixing seat body 90 and the threaded hole 1041 on the needle plate 10, and through the hole 9042 on the fixing seat body 90 and another threaded hole (not shown) on the needle plate 10. For a piezoelectric jacquard that uses a probe to transmit a driving signal to a driving circuit board, a plurality of probe holes 905 are also provided on the fixing seat body 90.

[0021] See also Figure 3 , Figure 4 , which also shows a screw blocking mechanism of the present invention. Specifically, the piezoelectric jacquard 100 also has a cover shell 80. The cover shell 80 is provided with a clamping portion 801 and screw blocking portions 8051, 8052 at its rear end. Correspondingly, a clamping slot 901 is provided at the rear of the fixing seat body 90, and the clamping slot 901 is configured so that when the clamping portion 801 is clamped into the clamping slot 901, the blocking portions 8051, 8052 at the rear end of the cover shell 80 can respectively prevent the screws 951, 952 from making axial movement along their central axes, but do not affect the screws 951, 952 from making rotational movement around their central axes. Figure 3 As shown, a buckling portion 802 may be further provided on the cover shell 80 , and a buckling groove 102 cooperating with the buckling portion 802 may be provided on the needle plate 10 , and the cooperation of the two realizes the connection between the cover shell 80 and the needle plate 10 .

[0022] Preferably, protrusions 9031 and 9032 are provided on the fixing seat body 90. The protrusions 9031 and 9032 can also pass through the hole 7031 and another hole (not shown) provided on the driving circuit board 70 respectively to support the circuit board.

[0023] Figure 4 9 is a schematic side view of the jacquard bar mounting system of the present invention after it has been installed. Although only the situation on the side of screw 951 is shown, the situation on the side of screw 952 is the same as the situation on the side of screw 951. Figure 4As shown, when the jacquard comb bar installation system of the present invention is installed, the screw 951 passes through the threaded hole (not shown) on the slider 981 partially located in the slide slot and abuts against the tail end 101 of the jacquard needle plate 10, while the other part of the slider 981 is snapped into the installation slot of the comb bar 200, so as to realize the reliable connection between the jacquard 100 and the comb bar 200. At the same time, the snap-in portion 801 of the cover 80 is snapped into the snap-in slot of the fixing seat body 90, and the blocking portion at the tail end of the cover 80 prevents the screw 951 from making axial movement along its central axis, but does not affect the screw 951 from making rotational movement around its central axis. In this way, when the operator needs to remove the jacquard from the comb bar 200, he only needs to use a tool (such as a hexagonal wrench) to rotate the screw 951. Since the screw 951 cannot move axially along its central axis, the slider 981 cannot rotate around the central axis (not shown) of the screw 951 in the slider groove, but can only move axially along the central axis of the screw 951. At this time, the slider 981 will move along the central axis of the screw 951 and release the cooperation with the comb bar 200, thereby removing the jacquard from the comb bar. When the jacquard needs to be installed on the comb bar, it is only necessary to rotate the screw 951 in the opposite direction. Therefore, the design of the present invention will not have the problem of the screw 951 falling off, so the potential safety hazard caused by the screw falling off can be eliminated. The present invention also does not need to use a spring, thereby eliminating the interference that may be caused by the existence of the spring.

[0024] Although the above embodiment describes the present invention with two screws, two sliders and two slider slots separated from each other, it is understood by those skilled in the art that the purpose of the present invention can be achieved by only using one screw, one slider and one slider slot having the features of the present invention. It is also understood by those skilled in the art that the screw blocking mechanism of the present invention is not limited to the combination of Figure 3 , Figure 4 In the described situation, for example, the screw blocking mechanism can also be separately provided on the jacquard mount, such as being a separate component fixedly connected to the tail of the jacquard mount, as long as its position and structure can block the axial movement of the screw along its central axis but not block the rotational movement of the screw along its central axis.

[0025] Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention defined by the appended claims is not limited to the specific details described in the above description, and many obvious changes to the present invention without departing from the spirit or scope of the present invention may also achieve the purpose of the present invention.
