Description

Technical Field

[0001] The present disclosure relates to the technical field of knitting needle detector installation, and in particular to an installation auxiliary device for a knitting needle detector. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine, has many loop forming systems, high speed, high output, fast pattern change, good fabric quality and other excellent effects. The knitting needle is a main loop forming part on the knitting machine, which is used to weave the yarn into coils and connect the coils into knitted fabrics. The structure and shape of the knitting needle affect the knitting process, the productivity of the knitting machine and the quality of the product, and is an important basis for the design of the knitting machine. Therefore, on the existing knitting machines, a knitting needle detector is set to monitor in real time whether the knitting needle is bent or damaged.

[0003] Since the detector requires a certain height and angle to align with the knitting needles, in the prior art, the knitting needle detector is first fixedly installed using a specific knitting needle detector mounting bracket, and then a door-like bracket is used to fix the knitting needle detector mounting bracket, and then the door-type bracket is installed to the corresponding predetermined screw hole position of the knitting machine plate by bolts, so as to finally fix the knitting needle detector so that the knitting needle detector can be aligned with the knitting needle for continuous monitoring.

[0004] At present, the door-type bracket is generally fixed directly on the knitting machine plate by bolts. Due to the various types of knitting machines on the market, when installing the door-type bracket to fix the needle detector, the door-type bracket may be installed at a relatively biased position, so that the needle detector cannot effectively align with the needle for monitoring. If the installation position of the door-type bracket is changed, it may be necessary to re-drill threaded holes on the knitting machine for installation, which will cause certain damage to the knitting machine. At the same time, if the generated powder enters the interior of the knitting machine, it is very likely to cause the knitting machine to work abnormally. In addition, the structure of the current door-type bracket is relatively fixed and cannot be adjusted, making it difficult to adjust the position of the needle detector to monitor the needle. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary installation device for a knitting needle detector, which solves the problem that the installation position of a gate-type bracket for installing a knitting needle detector on some knitting machines cannot be adjusted, resulting in the knitting needle detector being unable to effectively align with the knitting needle for monitoring.

[0006] To achieve the above-mentioned purpose, the first aspect of the present disclosure provides an auxiliary installation device for a knitting needle detector, comprising: A door frame, used for connecting with a knitting needle detector mounting bracket; an auxiliary mounting plate, on which a connection and locking assembly is provided, so as to fix the auxiliary mounting plate to the knitting machine through the connection and locking assembly; An adjusting and fixing structure is arranged on the auxiliary mounting plate and connected to the portal frame so as to fix the portal frame to the auxiliary mounting plate and enable the portal frame to be offset relative to the auxiliary mounting plate through the adjusting and fixing structure.

[0007] In some embodiments, adjusting the fixing structure includes: Two fixing plates are provided, the two fixing plates are respectively connected to two sides of the portal frame, and the two fixing plates are symmetrically arranged relative to the center plane of the portal frame; Wherein, the two fixing plates are respectively provided with strip holes, and the two strip holes are symmetrically arranged relative to the center plane of the portal frame; The auxiliary mounting plate is provided with openings at positions corresponding to the two strip-shaped holes, and a fixing piece is provided between the opening and the strip-shaped holes to fix the fixing plate to the auxiliary mounting plate.

[0008] In some embodiments, the fixing member is a fixing bolt, the opening is a threaded hole, and the fixing bolt passes through the strip hole and is threadedly connected to the threaded hole.

[0009] In some embodiments, the strip-shaped holes on the fixing plate are arranged at an angle.

[0010] In some embodiments, the two threaded holes located on the auxiliary mounting plate are respectively arranged opposite to the center positions of the strip-shaped holes.

[0011] In some embodiments, along the first direction, the auxiliary mounting plate is provided with a plurality of first threaded holes at equal intervals, and the interval between two adjacent first threaded holes is the same as the interval between two openings; The first direction is a direction from the center of one of the fixing plates toward the center of the other fixing plate.

[0012] In some embodiments, along the second direction, a plurality of second threaded holes are provided on the auxiliary mounting plate, and the spacing between two adjacent second threaded holes is the same as the spacing between the two openings; The second direction is a direction perpendicular to the first direction.

[0013] In some embodiments, the portal frame includes two oppositely disposed vertical plates and a connecting plate connected between the two vertical plates; The two fixing plates are respectively connected to the two vertical plates.

[0014] By adopting the above technical solution, through the setting of structures such as the door frame and the adjustment fixing structure, when the knitting needle detector cannot effectively align with the knitting needle, the adjustment fixing structure can be used to adjust the position of the door frame so that the knitting needle detector can accurately align with the knitting needle for monitoring. In this way, it is more convenient to adjust the position of the detector, increase its adjustable space, and better ensure that the detector is aligned with the knitting needle. Even if the device is set on different types of knitting machines, the position of the knitting needle detector can be effectively adjusted to align with the knitting needle for monitoring. In addition, the adjustment process is also more convenient, which is convenient for staff to operate and improves work efficiency.

[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] The present invention provides an auxiliary installation device for a knitting needle detector, such as Figure 1 , Figure 2 and Figure 3 As shown, the installation auxiliary device for the knitting needle detector comprises a door frame 1, an auxiliary mounting plate 2 and an adjustment fixing structure 3, wherein the door frame 1 is used to connect with the knitting needle detector mounting bracket, and a connection locking component 4 is arranged on the auxiliary mounting plate 2 to fix the auxiliary mounting plate 2 to the knitting machine through the connection locking component 4. The adjustment fixing structure 3 is arranged on the auxiliary mounting plate 2 and connected to the door frame 1 to fix the door frame 1 to the auxiliary mounting plate 2, and the door frame 1 can be offset relative to the auxiliary plate through the adjustment fixing structure 3.

[0028] Through the setting of this structure, after the knitting needle detector is fixed by using the knitting needle detector mounting bracket, the knitting needle detector mounting bracket can be directly connected to the door frame 1, and the door frame 1 can be installed on the auxiliary mounting plate 2, and then the auxiliary mounting plate 2 can be directly installed on the knitting machine through the connection locking component 4. In this way, when the knitting needle detector cannot effectively align with the knitting needle, the position of the door frame 1 can be adjusted by using the adjustment fixing structure 3, thereby driving the adjustment of the knitting needle detector mounting bracket, so that the knitting needle detector can accurately align with the knitting needle for monitoring, and then the door frame 1 can be fixed to the auxiliary mounting plate 2 by using the adjustment fixing structure 3. In this way, when installing the knitting needle detector, it is more convenient to adjust the position of the detector, increase its adjustable space, and better ensure that the detector is aligned with the knitting needle. Even if it is difficult for the knitting needle detector to align with the knitting needle for different types of knitting machines, after setting this knitting needle detector installation auxiliary device, the position of the knitting needle detector can be effectively adjusted to align it with the knitting needle for monitoring. In addition, during the adjustment process, the knitting needle detector can be adjusted by simply adjusting the door frame 1 and the fixing structure 3, making it more convenient to adjust it, thereby facilitating the operation of the staff and improving work efficiency.

[0029] In some embodiments, Figure 2 and Figure 3 As shown, the adjustment and fixing structure 3 includes two fixing plates 31, and the two fixing plates 31 are respectively connected to the two sides of the portal frame 1, and the two fixing plates 31 are symmetrically arranged relative to the center line of the portal frame 1, wherein the two fixing plates 31 are respectively provided with strip holes 311, and the two strip holes 311 are also symmetrically arranged relative to the center line of the portal frame 1. In addition, openings 21 are respectively arranged at the positions of the auxiliary mounting plate 2 corresponding to the strip holes 311 on the two fixing plates 31, and fixing members are arranged between the openings 21 and the strip holes 311 to fix the fixing plates 31 to the auxiliary mounting plate 2.

[0030] In this way, after the fixing plate 31 is fixed to the auxiliary mounting plate 2 by the fixing piece, the door frame 1 can be fixed to the auxiliary mounting plate 2 relatively stably to ensure that the needle detector monitors the pointer. When the position of the needle detector needs to be adjusted, the fixing piece only needs to be relatively opened to ensure that the fixing plate 31 is offset along the position track of the strip hole 311, thereby adjusting the position of the needle detector. This method is also more convenient to adjust and is easy for the staff to operate.

[0031] like Figure 2 and Figure 3 As shown, the fixing member is a fixing bolt 32 , the opening 21 is a threaded hole, and the fixing bolt 32 passes through the strip hole 311 and is threadedly connected to the threaded hole.

[0032] By utilizing the setting of the fixing bolt 32, when fixing the portal frame 1, it is only necessary to make the fixing bolt 32 pass through the strip hole 311 and connect to the threaded hole, and then the nut of the fixing bolt 32 is pressed onto the fixing plate 31 to fix the portal frame 1. When the position of the portal frame 1 needs to be adjusted later, it is only necessary to loosen the fixing bolt 32 relatively, so that the strip groove on the fixing plate 31 can be offset relative to the fixing bolt 32, so that the portal frame 1 is offset. After moving, the fixing bolt 32 can be tightened again to fix the portal frame 1.

[0033] Further, such as Figure 2 As shown, the strip-shaped holes 311 on the fixing plate 31 are arranged at an angle.

[0034] By setting the strip holes 311 at an angle, since the strip holes 311 on the two fixing plates 31 are symmetrically arranged, after the fixing parts are relatively loosened, the portal frame 1 can be rotated relative to the auxiliary mounting plate 2, thereby ensuring the adjustment space of the portal frame 1 to a great extent, making the needle detector offset at a larger angle, so as to more effectively align the needles on the knitting machine.

[0035] In a further embodiment, Figure 3 As shown, the two threaded holes on the auxiliary mounting plate 2 are respectively arranged opposite to the center of the strip hole 311. That is, after the door frame 1 is mounted on the auxiliary mounting plate 2 by the fixing bolts 32, the two fixing bolts 32 are respectively located at the center of each strip hole 311.

[0036] In this way, when adjusting the portal frame 1 subsequently, the rotation adjustment space of the portal frame 1 can be maximized, which greatly improves the adjustment space of the portal frame 1, that is, increases the adjustment space of the needle detector, and better ensures that this device can effectively match various different models.

[0037] In some embodiments, Figure 2 and Figure 3 As shown, the direction from the center of one fixing plate 31 toward the center of the other fixing plate 31 is defined as a first direction. Along the first direction, a plurality of first threaded holes 22 are evenly spaced on the auxiliary mounting plate 2, and the spacing between two adjacent first threaded holes 22 is the same as the spacing between the two openings 21.

[0038] By setting a plurality of first threaded holes 22, when the door frame 1 still cannot align the knitting needle detector with the knitting needle even after adjusting the fixing structure 3, the door frame 1 can be disassembled from the original position and replaced to be installed at the position of other first threaded holes 22, so as to further adjust the position of the knitting needle detector. Due to the setting of a plurality of first threaded holes 22, more space is given to the door frame, thereby giving the knitting needle detector a larger adjustment space.

[0039] In other embodiments, in combination Figure 4 As shown, a direction perpendicular to the first direction is defined as a second direction. Along the second direction, a plurality of second threaded holes 23 are provided on the auxiliary mounting plate 2 , and a distance between two adjacent second threaded holes 23 is the same as a distance between two openings 21 .

[0040] By setting up multiple second threaded holes 23, the portal frame 1 can be given more installation and replacement space in the second direction, thereby giving the needle detector a larger adjustment space along the second direction, making the installation position of the needle detector more diversified, so that this device can better match various types of knitting machines.

[0041] In some embodiments, Figure 2 As shown, the portal frame 1 comprises two oppositely disposed vertical plates 11 and a connecting plate 12 fixedly connected between the two vertical plates 11 , and the two fixing plates 31 are fixedly connected to the two vertical plates 11 , respectively.

[0042] When the portal frame 1 is set on the auxiliary mounting plate 2 , the two fixing plates 31 are attached to the auxiliary mounting plate 2 , so that the fixing plates 31 can be better fixed to the auxiliary mounting plate 2 .

[0043] It should be noted that the center plane of the portal frame 1 disclosed above is a plane parallel to the vertical plates 11 and located at the center line of the connecting plate 12 relative to the two vertical plates 11 .

[0044] It should also be noted that the above-mentioned door frame 1 and the knitting needle detector mounting bracket can be directly fixedly connected, or connected by a bolt locking structure. For example, the knitting needle detector mounting bracket can be directly set at the door frame 1, that is, the knitting needle detector mounting bracket is extended between the two vertical plates 11, and then the bolts are directly passed through the knitting needle detector mounting bracket and the door frame 1 to connect and fix them. Of course, the door frame 1 and the knitting needle detector mounting bracket can also be connected by other structures, as long as the door frame 1 and the knitting needle detector mounting bracket can be relatively fixed.

[0045] In some embodiments, Figure 1 and Figure 5 As shown, the above-mentioned connecting and locking assembly 4 includes a base plate 41, a rotating fixing structure 42 and a movable locking structure 43, wherein the rotating fixing structure 42 is arranged at one end of the base plate 41 and is connected to the auxiliary mounting plate 2 so that the auxiliary mounting plate 2 can rotate and be fixed relative to the base plate 41; the movable locking structure 43 is arranged at the other end of the base plate 41 to fix the base plate 41 to the knitting machine and enable the base plate 41 to move relative to the knitting machine.

[0046] Through the above structure, after the base plate 41 is fixed by the movable locking structure 43, when the knitting needle detector set on the door frame 1 still cannot be aligned with the knitting needle, the movable locking structure 43 can be used to control the relative movement of the base plate 41 to move the auxiliary mounting plate 2, thereby further adjusting the position of the knitting needle detector. In addition, the position of the knitting needle detector can also be adjusted by controlling the rotation of the auxiliary mounting plate 2 by rotating the fixing structure 42 to give the knitting needle detector a larger adjustment space. Furthermore, using this device, after the base plate 41 is installed to the predetermined position, the knitting needle detector can still be adjusted to the corresponding position for detection, so that there is no need to perform operations such as punching holes on the knitting machine.

[0047] In some embodiments, in combination Figure 6 and Figure 7 As shown, the movable locking structure 43 includes a locking column 431 and a locking bolt 432, wherein a through hole 4311 is provided at the center of the locking column 431, and a movable bar hole 411 is provided on the bottom plate 41. One end of the locking column 431 is arranged close to the bottom plate 41, and the locking bolt 432 passes through the movable bar hole 411 and the through hole 4311 on the locking column 431.

[0048] Thus, during installation, the locking column 431 can be placed at the predetermined screw hole on the knitting machine plate, so that the through hole 4311 on the locking column 431 is facing the predetermined screw hole, and then the locking bolt 432 is passed through the through hole 4311 and connected to the predetermined screw hole, and the nut of the locking bolt 432 is pressed against the bottom plate 41, so that the bottom plate 41 can be stably fixed to the knitting machine, and there is no need to drill holes on the knitting machine plate due to installation problems. When the position needs to be adjusted later, only the locking bolt 432 needs to be loosened to control the bottom plate 41 to move along the track of the moving strip hole 411.

[0049] Furthermore, the above-mentioned movable locking structure 43 also includes a limit block 433, which is connected to one end of the locking column 431 attached to the bottom plate 41, and the limit block 433 extends into the movable bar hole 411, wherein the width of the limit block 433 is the same as the width of the movable bar hole 411.

[0050] In this way, when the locking bolt 432 is loosened to adjust the position of the base plate 41, the limit block 433 can provide a limit to the base plate 41 so that it can only move in one direction, thereby preventing the base plate 41 from suddenly rotating arbitrarily when the locking bolt 432 is loosened, causing structures such as the needle detector to collide with other structures and cause damage.

[0051] like Figure 7 As shown, the moving bar hole 411 is arc-shaped, and the limiting block 433 is also arc-shaped.

[0052] By setting the movable bar hole 411 and the fiber block to be in an arc shape, the bottom plate 41 can be adjusted to give the knitting needle detector a certain offset in a direction perpendicular to the bottom plate 41, so that the knitting needle detector can be adjusted in different directions.

[0053] In some embodiments, Figure 5 , Figure 6 and Figure 8 As shown, the above-mentioned rotating fixed structure 42 includes a fixed column 421, a sliding bar hole 422, a slider 423 and a positioning bolt 424, wherein one end of the fixed column 421 is arranged in contact with the bottom plate 41, and the other end is arranged in contact with the auxiliary mounting plate 2, the sliding bar hole 422 is arranged on the bottom plate 41, and the above-mentioned slider 423 is T-shaped, the slider 423 is slidably arranged in the sliding bar hole 422, and is arranged corresponding to the fixed column 421, and a fixing screw hole is arranged on the slider 423. One end of the positioning bolt 424 passes through the auxiliary mounting plate 2 and the fixed column 421, and is connected to the fixing screw hole, the nut of the positioning bolt 424 is pressed against the auxiliary mounting plate 2, and the positioning bolt 424 locks the slider 423 to the bottom plate 41.

[0054] By using this structure, the bottom plate 41 and the auxiliary mounting plate 2 can be relatively fixed. When the auxiliary mounting plate 2 needs to be rotated to adjust the needle detector, the positioning bolt 424 can be loosened to rotate the auxiliary mounting plate 2. After the rotation is completed, the positioning bolt 424 can be tightened again to fix it. At the same time, when the positioning bolt 424 is loosened, the T-shaped slider 423 is loosened relative to the bottom plate 41, and the slider 423 can move along the sliding bar hole 422 to achieve lateral movement. After that, the positioning bolt 424 is tightened to lock the slider 423 to the bottom plate 41 to achieve the effect of mutual fixation.

[0055] In some embodiments, Figure 5 and Figure 8 As shown, a transverse bar hole 5 is provided at a position of the auxiliary mounting plate 2 corresponding to the fixing column 421 , and the positioning bolt 424 passes through the transverse bar hole 5 , and the diameter of the positioning bolt 424 is the same as the width of the transverse bar hole 5 .

[0056] By utilizing the arrangement of the transverse strip holes 5, when the positioning bolts 424 are loosened, the auxiliary mounting plate 2 can be rotated and can also be moved along the track of the transverse strip holes 5, thereby increasing the adjustable space of the needle detector.

[0057] Furthermore, the rotation and fixing structure further includes a gasket 425 , which is sleeved onto the positioning bolt 424 and is located between the nut of the positioning bolt 424 and the auxiliary mounting plate 2 .

[0058] By setting the gasket 425, the contact area of ​​the nut of the positioning bolt 424 on the auxiliary mounting plate 2 can be increased, so that the positioning bolt 424 can more stably fix the auxiliary mounting plate 2 and ensure the connection stability.

[0059] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0061] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
