Description

Technical Field

[0001] This application relates to the field of loom technology, and in particular to a needle plate structure and insert plate installation tool for a computerized flat knitting machine. Background Technology

[0002] The needle plate of a computerized flat knitting machine is a structure used to hold crochet needles. It typically includes a needle plate body and a baffle. The baffle is installed on the needle plate by slotting the needle plate body, so as to form a needle groove in the needle plate structure to accommodate the crochet needle.

[0003] The drawback of this type of computerized flat knitting machine needle plate is that the number of channels on the surface of the needle plate body is the same as the number of baffles, which leads to a decrease in the overall rigidity of the needle plate. When the drive component drives the hook needle to work, the needle plate body is prone to deformation, which can easily cause the knitting machine to stop, affecting the production efficiency of the knitting machine, and even damaging the hook needle, the needle plate body and the drive components of the knitting machine, thus affecting the service life of the equipment. Summary of the Invention

[0004] This application provides a needle plate structure and a needle plate installation tool for a computerized flat knitting machine, which improves the rigidity of the needle plate structure, thereby improving the working continuity and service life of the computerized flat knitting machine.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a needle plate structure for a computerized flat knitting machine, including a needle plate body, a main insert plate, an insert plate mounting bracket, and auxiliary insert plates. A preset straight line is defined. Multiple first slots are formed on the needle plate body, and the multiple first slots are arranged along the preset straight line. Multiple main insert plates are arranged along the preset straight line, and the main insert plates are parallel to the extension direction of the first slots. At least a portion of the main insert plates are inserted into the first slots. The insert plate mounting bracket is placed along the preset straight line and connected to the main insert plates. The insert plate mounting bracket forms second slots, which are located between adjacent main insert plates. Multiple auxiliary insert plates are arranged along the preset straight line, and at least a portion of the auxiliary insert plates are inserted into the second slots to form needle grooves between the auxiliary insert plates and the main insert plates. The preset straight line, the thickness direction of the needle plate body, and the extension direction of the first slots are all perpendicular to each other.

[0007] Furthermore, the main insert plate has a connecting groove that penetrates the main insert plate along a predetermined straight line; the connecting groove is located in the middle of the main insert plate along the thickness direction of the needle plate body; the insert plate mounting bracket is at least partially inserted into the connecting groove.

[0008] Furthermore, the end of the auxiliary insert plate facing the main body of the needle plate has a plug-in portion, which is at least partially inserted into the second slot.

[0009] Furthermore, the end of the sub-insertion plate facing the needle plate body has an abutment surface, which at least partially abuts against the end of the insertion plate mounting bracket facing the sub-insertion plate.

[0010] Furthermore, a limiting groove is formed at the end of the needle plate body facing the main insertion plate, and the limiting groove extends along a preset straight line direction; the insertion plate mounting bracket is at least partially installed in the limiting groove.

[0011] Furthermore, the needle plate structure also includes a positioning rod, which is installed on the needle plate body and extends along a predetermined straight line; a first positioning opening is formed at the end of the main insert plate facing the needle plate body; at least a portion of the positioning rod abuts against the first positioning opening.

[0012] Furthermore, a first slot is formed at the end of the main insert plate away from the main body of the needle plate; a second slot is formed at the end of the auxiliary insert plate away from the main body of the needle plate; the needle plate structure also includes a spacer, which is connected to the first slot and the second slot respectively, and the spacer extends at least partially into the needle slot to maintain the distance between the main insert plate and the auxiliary insert plate.

[0013] Furthermore, along the extension direction of the first slot, a mounting portion is formed at one end of the main insert plate; the pin plate structure also includes a settling plate, which is located between adjacent main insert plates and is connected to the mounting portion via a connecting shaft.

[0014] Furthermore, the settling plate includes at least two arc-shaped grooves with overlapping trajectories; the connecting shaft is installed inside the arc-shaped grooves.

[0015] Furthermore, the needle plate structure includes a partition plate, which is installed at the end of the mounting portion away from the needle plate body; a groove is formed on the partition plate, and a settling plate extends through the groove to both ends of the partition plate along the thickness direction of the needle plate body, and the settling plate has a degree of freedom of movement relative to the groove.

[0016] Secondly, embodiments of this application also provide a plate mounting tool for mounting the above-mentioned needle plate structure; the plate mounting tool includes a mounting bracket and a guide plate assembly, the mounting bracket being at least partially inserted into the second slot; the guide plate assembly is located between adjacent main plates, and a guide groove is formed in the guide plate assembly, and the second slot is located in the guide groove when viewed along the thickness direction of the needle plate body.

[0017] By mounting the main insert plate on the needle plate body and then mounting the auxiliary insert plate on the main insert plate, the number of slots for mounting insert plates on the needle plate body is reduced, thereby increasing the strength of the needle plate body and improving the working continuity and service life of the computerized flat knitting machine.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, in one implementation, this application provides a needle plate structure for a computerized flat knitting machine, including a needle plate body 1, a main insert plate 2, an insert plate mounting bracket 3, a secondary insert plate 4, and a hook needle 20. The needle plate body 1 is used to provide a mounting base for the main insert plate 2 and the insert plate mounting bracket 3. The main insert plate 2 and the secondary insert plate 4 are used to form a needle groove for accommodating the hook needle 20 so that the hook needle can slide on the needle plate body 1. The insert plate mounting bracket 3 is used to provide a mounting position for the secondary insert plate 4.

[0048] Specifically, a preset straight line 10 is defined, and the needle plate body 1 extends along the direction of the preset straight line 10.

[0049] Along the thickness direction of the needle plate body 1, a plurality of first slots 101 are formed on the upper end surface of the needle plate body 1, and the plurality of first slots 101 are evenly arranged along a preset straight line 10.

[0050] The first slot 101 is perpendicular to the upper surface of the needle plate body 1, ensuring that the main insert plate 2 is perpendicular to the upper surface of the needle plate body 1, so as to place the auxiliary insert plate 4 in a position parallel to the main insert plate 2, thereby improving the ease of installation of the auxiliary insert plate 4.

[0051] Multiple main insert plates 2 are arranged along a preset straight line 10. The main insert plates 2 are at least partially inserted into the first slot 101, and the main insert plates 2 are parallel to the extension direction of the first slot 101, thereby increasing the contact area between the main insert plates 2 and the first slot 101 and improving the connection stability between the main insert plates 2 and the needle plate body 1.

[0052] The insert plate mounting bracket 3 is placed along the preset straight line 10 and is connected to the adjacent main insert plate 2. By setting the insert plate mounting bracket 3, the spacing between the adjacent main insert plates 2 can be guaranteed, thereby further improving the connection stability between the main insert plate 2 and the needle plate body 1.

[0053] The insert mounting bracket 3 has a second slot 301, which is located between adjacent main insert plates 2.

[0054] Multiple auxiliary insert plates 4 are arranged along a preset straight line 10. The auxiliary insert plates 4 are at least partially inserted into the second slot 301, thereby connecting the auxiliary insert plates 4 with the main insert plate 2, reducing the number of slots in the needle plate body 1 and increasing the strength of the needle plate body 1.

[0055] The auxiliary insert plate 4 and the main insert plate 2 are arranged parallel to each other, thereby forming a needle groove between the auxiliary insert plate 4 and the main insert plate 2. The hook 20 is placed on the needle plate body 1 through the needle groove.

[0056] By installing the main insert plate 2 on the needle plate body 1 and then installing the auxiliary insert plate 4 on the main insert plate 2, the number of slots for installing insert plates in the needle plate body 1 is reduced, thereby increasing the strength of the needle plate body 1 and improving the working continuity and service life of the computerized flat knitting machine.

[0057] The thickness direction of the preset straight line 10 and the extension direction of the needle plate body 1 are perpendicular to each other.

[0058] It should be noted that the main insert plate 2 and the auxiliary insert plate 4 are perpendicular to the preset straight line 10, that is, the main insert plate 2 and the auxiliary insert plate 4 are parallel to the plane containing the thickness direction of the needle plate body 1 and the extension direction of the first slot 101, respectively.

[0059] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are front, back, left, right, up, and down. The extension direction of the first slot 101 is... Figure 1 The forward and backward directions are shown. The extension direction of the preset straight line 10 is... Figure 1 The left and right directions are shown. The thickness direction of the needle plate body 1 is... Figure 1 The up and down directions are shown.

[0060] like Figure 5 As shown, in one implementation, the first slot 101 extends through the needle plate body 1 in the front-to-back direction to facilitate the installation of the main insert plate 2 onto the needle plate body 1.

[0061] Meanwhile, the first slot 101 does not penetrate the needle plate body 1 in the vertical direction, that is, the first slot 101 has a recessed structure in the vertical direction, which further facilitates the installation of the main insert plate 2 onto the needle plate body 1.

[0062] As another implementation, the first slot 101 does not penetrate the main body of the pin plate 1 in the front-back direction, which facilitates the positioning of the main insert plate 2 in the front-back direction.

[0063] As another implementation, the first slot 101 extends through the needle plate body 1 in the front-to-back direction and in the up-down direction, which facilitates the processing of the needle plate body 1.

[0064] It should be noted that this application describes the first slot 101 as penetrating the needle plate body 1 in the front-to-back direction, while the first slot 101 does not penetrate the needle plate body 1 in the up-down direction.

[0065] As one implementation, the depth of the first slot 101 in the vertical direction is less than or equal to one-third of the height of the main insert plate 2 in the vertical direction. This ensures that the main insert plate 2 can be stably inserted into the needle plate body 1. On the other hand, it prevents the insertion depth of the main insert plate 2 from being too large, which would make the depth of the needle groove formed by the main insert plate 2 and the auxiliary insert plate 4 too shallow, thereby improving the stability of the movement of the hook 20.

[0066] like Figure 3As shown, in one implementation, the main insert plate 2 has a connecting groove 201, which penetrates the main insert plate 2 along a preset straight line 10. The insert plate mounting bracket 3 is at least partially inserted into the connecting groove 201, and the main insert plate 2 and the insert plate mounting bracket 3 are connected through the connecting groove 201, thereby improving the installation convenience of the insert plate mounting bracket 3.

[0067] As another implementation method, the insert mounting bracket 3 can be fixed between adjacent main insert plates 2 by means of welding or other methods.

[0068] As a third implementation method, the insert plate mounting bracket 3 is a partition structure. The insert plate mounting bracket 3 is placed between the main insert plate 2 and the auxiliary insert plate 4. The insert plate mounting bracket 3 separates the main insert plate 2 and the auxiliary insert plate 4, thereby forming a pin groove between the main insert plate 2 and the auxiliary insert plate 4.

[0069] In this implementation, the auxiliary insert plate 4 is placed directly above the needle plate body 1.

[0070] It should be noted that this application describes the connection between the insert plate mounting bracket 3 and the main insert plate 2 via the connecting groove 201.

[0071] As one implementation, along the thickness direction of the needle plate body 1, the connecting groove 201 is located in the middle of the main insert plate 2, that is, the connecting groove 201 is located in the middle of the height direction of the main insert plate 2, so as to allow the insert plate mounting bracket 3 to at least partially abut against the upper end face of the needle plate body 1, thereby improving the installation stability of the insert plate mounting bracket 3, and further improving the installation stability of the auxiliary insert plate 4.

[0072] In one implementation, the connecting slot 201 can be located at the bottom or top of the main insert plate 2 in the height direction.

[0073] It should be noted that this application describes the connection groove 201 as being located at the center of the height direction of the main insert plate 2.

[0074] As one implementation method, the insert plate mounting bracket 3 is inserted into the connecting groove 201 by means of interference fit or transition fit, so that at least part of the side wall of the insert plate mounting bracket 3 abuts against at least part of the inner wall of the connecting groove 201, ensuring that the position of the insert plate mounting bracket 3 and the main insert plate 2 is fixed, preventing the change of the needle groove width caused by the movement of the main insert plate 2 during the use of the needle plate structure, and improving the consistency of the needle groove width.

[0075] like Figure 4 As shown, as another implementation, a positioning post 2011 extending downward is formed on the top end face of the connecting groove 201 in the vertical direction.

[0076] Correspondingly, a positioning groove 302 is formed on the upper end surface of the insert mounting bracket 3.

[0077] During installation, the main body 1 of the needle plate supports the mounting bracket 3. Under the gravity of the main plate 2, the positioning post 2011 on the main plate 2 moves into the positioning groove 302, thereby locking the main plate 2 and the mounting bracket 3. During the use of the needle plate structure, this prevents the needle groove width from changing due to the movement of the main plate 2, thus improving the consistency of the needle groove width.

[0078] In this implementation, when viewed from the top and bottom, the shape of the positioning groove 302 is different from the shape of the second slot 301, so as to distinguish the installation positions of the main insert plate 2 and the auxiliary insert plate 4 and improve the installation convenience of the main insert plate 2 and the auxiliary insert plate 4.

[0079] It should be noted that this application describes the insert mounting bracket 3 being inserted into the connecting slot 201 by means of interference fit or transition fit.

[0080] like Figure 3 As shown, as one implementation method, the insert mounting bracket 3 is a single-section structure, which allows the insert mounting bracket 3 to pass through all the main inserts 2. That is, all the sub-inserts 4 can be installed through a single insert mounting bracket 3, thereby improving the installation convenience and installation accuracy of the sub-inserts 4.

[0081] As another implementation, the insert mounting bracket 3 can be multi-segmented, connecting two or more main insert plates 2. The multi-segmented insert mounting bracket 3 facilitates the assembly of the insert mounting bracket 3 with the main insert plates 2.

[0082] It should be noted that this application describes the insert mounting bracket 3 as a single-section structure.

[0083] like Figure 3 and Figure 5 As shown, in one implementation, a limiting groove 102 is formed at the end of the needle plate body 1 facing the main insert plate 2. The limiting groove 102 extends along the direction of the preset straight line 10. The insert plate mounting bracket 3 is at least partially installed in the limiting groove 102, that is, the lower end face of the insert plate mounting bracket 3 at least partially abuts in the limiting groove 102, thereby improving the stability of the insert plate mounting bracket 3 and thus improving the installation stability of the auxiliary insert plate 4. At the same time, the main insert plate 2 and the auxiliary insert plate 4 can be positioned in the up, down and back and forth directions by the insert plate mounting bracket 3, further improving the installation accuracy of the main insert plate 2 and the auxiliary insert plate 4.

[0084] It should be noted that the needle plate structure of this application includes multiple insert plate mounting brackets 3, which are arranged in the front-to-back direction, and the auxiliary insert plate 4 is installed through the multiple insert plate mounting brackets 3. At the same time, multiple limiting grooves 102 are formed on the needle plate body 1 to facilitate the limiting of each insert plate mounting bracket 3.

[0085] like Figure 3As shown, in one implementation, the end of the sub-insertion plate 4 facing the needle plate body 1 has a plug-in portion 401. The plug-in portion 401 is at least partially plugged into the second slot 301. The sub-insertion plate 4 and the insertion plate mounting bracket 3 are assembled by the cooperation of the plug-in portion 401 and the second slot 301, thereby improving the installation stability of the sub-insertion plate 4.

[0086] The cross-section of the insertion part 401 is consistent with the cross-sectional shape of the second slot 301, which can ensure the installation stability of the auxiliary insertion plate 4 and the insertion plate mounting bracket 3.

[0087] As one implementation, the insert plate mounting bracket 3 forms at least one second slot 301 between adjacent main insert plates 2 to facilitate the installation of at least one auxiliary insert plate 4 between adjacent main insert plates 2, further reducing the number of first slots 101 on the needle plate body 1 and improving the strength of the needle plate body 1.

[0088] When the insert mounting bracket 3 forms two or more second slots 301 between adjacent main insert plates 2, two or more auxiliary insert plates 4 are installed between adjacent main insert plates 2, and pin grooves are formed between adjacent main insert plates 2, auxiliary insert plates 4 and adjacent auxiliary insert plates 4.

[0089] As one implementation, the end of the sub-insertion plate 4 facing the needle plate body 1 has an abutment surface 402. The abutment surface 402 at least partially abuts against the end of the insertion plate mounting bracket 3 facing the sub-insertion plate 4. The abutment surface 402 increases the contact area between the sub-insertion plate 4 and the insertion plate mounting bracket 3, thereby improving the installation stability of the sub-insertion plate 4.

[0090] It should be noted that the contact surface 402 can be located on the same plane as the bottom end face of the sub-insertion plate 4, or it can be a plane that protrudes from the bottom end face of the sub-insertion plate 4.

[0091] like Figure 3 and Figure 6 As shown, as one implementation method, the needle plate structure also includes a positioning rod 5, which is installed on the needle plate body 1 and extends along the preset straight line 10. The positioning rod 5 is used to position the main insert plate 2 and the auxiliary insert plate 4 in the front and rear directions.

[0092] Specifically, the end of the main insert plate 2 facing the needle plate body 1 has a first positioning port 202, and at least a portion of the positioning rod 5 abuts against the first positioning port 202. The main insert plate 2 is positioned in the front-back direction through the first positioning port 202 and the positioning rod 5.

[0093] It should be noted that the end of the auxiliary insert plate 4 facing the needle plate body 1 may have a second positioning port, and the structure of the second positioning port is the same as that of the first positioning port 202.

[0094] like Figure 3 and Figure 5 As shown, in one implementation, a mounting groove 103 is formed on the needle plate body 1. The mounting groove 103 extends along a preset straight line 10, and the positioning rod 5 is mounted on the needle plate body 1 through the mounting groove 103.

[0095] Specifically, the upper end of the mounting groove 103 is an open structure to facilitate the installation of the positioning rod 5 into the mounting groove 103.

[0096] The mounting groove 103 includes a first slope 1031, which is inclined relative to the vertical plane.

[0097] The first positioning port 202 includes a second slope 2021, which is inclined relative to the vertical plane.

[0098] The positioning and installation process of the main insert plate 2 and the auxiliary insert plate 4 using the positioning rod 5 is as follows.

[0099] (1) Install the main insert 2 into the first slot 101;

[0100] (2) Install the insert plate mounting bracket 3 on the adjacent main insert plate 2;

[0101] (3) Install the auxiliary insert plate 4 on the second slot 301;

[0102] (4) Install the positioning rod 5 in the mounting groove 103 and apply a forward force to the main insert plate 2 and the auxiliary insert plate 4 so that the first slope 1031 abuts against the front end of the positioning rod 5 and the second slope 2021 abuts against the rear end of the positioning rod 5.

[0103] The positioning rod 5 positions the main insert plate 2 and the auxiliary insert plate 4 in the front-back direction. At the same time, since the tilt direction of the first slope 1031 is opposite to that of the second slope 2021, the positioning rod 5 can limit the main insert plate 2 and the auxiliary insert plate 4 in the up-down direction, preventing the main insert plate 2 and the auxiliary insert plate 4 from separating from the needle plate body 1, and improving the assembly stability of the main insert plate 2, the auxiliary insert plate 4 and the needle plate body 1.

[0104] As one implementation, the end of the main insert plate 2 away from the needle plate body 1 has a first slot 203, and the end of the auxiliary insert plate 4 away from the needle plate body 1 has a second slot 403. The line connecting the first slot 203 and the second slot 403 is parallel to the preset straight line 10.

[0105] like Figure 3 and Figure 7 As shown, the needle plate structure also includes a spacer 6, which is connected to the first slot 203 and the second slot 403 respectively, and the spacer 6 extends at least partially into the needle groove to maintain the distance between the main insert plate 2 and the auxiliary insert plate 4, improve the positional accuracy of the main insert plate 2 and the auxiliary insert plate 4, and improve the accuracy of the needle groove.

[0106] Specifically, along the preset straight line 10, a partition groove 601 is uniformly formed on the partition 6. At least a portion of the main insert plate 2 or at least a portion of the auxiliary insert plate 4 is inserted into the partition groove 601. The distance between the main insert plate 2 and the auxiliary insert plate 4 is maintained by the portion of the partition 6 located in the adjacent partition groove 601.

[0107] It should be noted that the rear ends of the main insert plate 2 and the auxiliary insert plate 4 are also equipped with partition plates 6.

[0108] As one implementation method, a pressure plate 9 is installed at the end of the spacer 6 away from the main insert plate 2. The pressure plate 9 fixes the spacer 6 in the first slot 203 and the second slot 403, thereby improving the installation stability of the spacer 6.

[0109] like Figure 3 and Figure 6 As shown, as one implementation, the needle plate structure also includes a sinker plate 7, which is used to press the weaving thread down into the hook needle 20.

[0110] Along the extension direction of the first slot 101, the front end of the main insert plate 2 is formed with a mounting part 204, the settling plate 7 is connected to the mounting part 204 through the connecting shaft 12, and the settling plate 7 is located between adjacent main insert plates 2.

[0111] By shortening the length of the auxiliary insert plate 4 in the front-to-back direction, it is easier for the auxiliary insert plate 4 to avoid the settling plate 7, so that the settling plate 7 can be installed. At the same time, by installing the settling plate 7 on the main insert plate 2, the number of parts used to install the settling plate 7 can be reduced, simplifying the structure of the computerized flat knitting machine and thus reducing the production cost of the computerized flat knitting machine.

[0112] The settling plate 7 can swing relative to the connecting shaft 12, thereby changing the bottom height of the settling plate 7 so that the settling plate 7 can press down the weaving line.

[0113] As one implementation, the settling plate 7 includes at least two arc-shaped grooves 701, and two connecting shafts 12 are respectively installed in the two arc-shaped grooves 701, and the trajectory centers of the arc-shaped grooves 701 overlap to ensure that the settling plate 7 swings around the center of the trajectory circle.

[0114] like Figure 6 As shown, in one implementation, the needle plate structure includes a partition 8, which is installed on the end of the mounting portion 204 away from the needle plate body 1. The partition 8 is used to maintain the spacing between adjacent mounting portions 204.

[0115] Specifically, a partition groove 802 is formed on the partition 8, and the mounting part 204 is at least partially inserted into the partition groove 802, so that the part of the partition 8 located between adjacent partition grooves 802 extends into the adjacent mounting parts 204, thereby maintaining the distance between adjacent mounting parts 204.

[0116] A groove 801 is formed on the partition 8. Along the thickness direction of the needle plate body 1, the settling plate 7 extends to both ends of the partition 8 through the groove 801, and the settling plate 7 has the degree of freedom of movement relative to the groove 801.

[0117] The upper end of the settling plate 7 extends above the partition plate 8 and is connected to the settling plate 7 via an external drive device, thereby facilitating the swinging of the settling plate 7.

[0118] like Figure 3 , Figure 8 and Figure 9 As shown, in one implementation, the crochet hook 20 includes a main body 2001, a first connecting part 2002, a second connecting part 2003 and a third connecting part 2004 connected in sequence. The main body 2001 is used to hook the woven thread, and the first connecting part 2002 and the second connecting part 2003 are used to connect to an external drive block 21, which drives the crochet hook 20 to move back and forth.

[0119] Specifically, the second connection part 2003 includes a drive part 20031, which extends above the main insert plate 2 so as to connect the second connection part 2003 with the drive block 21.

[0120] The drive block 21 has an upper and lower guide surface 2101 and a front and rear guide surface 2102 at the end facing the hook 20. The front and rear guide surface 2102 is located below the upper and lower guide surface 2101. The upper and lower guide surface 2101 drives the hook 20 to move up and down, and the front and rear guide surface 2102 drives the hook 20 to move back and forth.

[0121] As one implementation method, the needle plate structure also includes a connecting post 11, which is placed along a preset straight line 10 and penetrates through the entire main insert plate 2 and the auxiliary insert plate 4. The connecting post 11 further improves the installation stability of the main insert plate 2 and the auxiliary insert plate 4.

[0122] The second connecting part 2003 includes a retaining part 20032, which is located behind the driving part 20031. The retaining part 20032 is adapted to the connecting post 11. By setting the retaining part 20032, the hook 20 can be kept in the pressed state by the connecting post 11, without the need for external parts to keep the hook 20 in the pressed state, thereby further simplifying the structure of the computerized flat knitting machine.

[0123] When the hook 20 moves backward, the retaining part 20032 abuts against the lower part of the connecting post 11, thereby keeping the hook 20 in a pressed state. When the hook 20 moves forward, the retaining part 20032 separates from the connecting post 11, causing the hook 20 to return to its upward position.

[0124] like Figure 10 , Figure 11 and Figure 12 As shown, in one implementation, in another aspect, this application also provides a plug-in board installation tool for installing the above-mentioned pin plate structure, thereby improving the installation efficiency of the main plug-in board 2 and the auxiliary plug-in board 4, and thus improving the installation efficiency of the pin plate structure.

[0125] Specifically, the insert plate installation tool 30 includes an installation bracket 3001 and a guide plate assembly 3002. The installation bracket 3001 is at least partially inserted into the second slot 301. The installation bracket 3001 is positioned by cooperating with the second slot 301 to ensure the installation accuracy of the main insert plate 2 and the auxiliary insert plate 4.

[0126] Furthermore, the mounting bracket 3001 includes a positioning plate 30011, a positioning block 30012, and a connecting block 30013. The positioning plate 30011 is arranged along the front-back direction and parallel to the main insert plate 2. The positioning block 30012 is arranged along the left-right direction and perpendicular to the main insert plate 2. The positioning plate 30011 is connected to one end of the positioning block 30012 along the left-right direction. The positioning block 30012 is fixed to the end face of the positioning plate 30011 facing away from the main insert plate 2.

[0127] When the insert plate installation tool is used, the positioning block 30012 is inserted into the second slot 301, thereby positioning and installing the mounting bracket 3001 on the insert plate mounting bracket 3.

[0128] Along the front-to-back direction, one end of the guide plate assembly 3002 is fixed to the connecting block 30013. A guide groove 3003 is formed in the guide plate assembly 3002. When viewed along the thickness direction of the needle plate body 1, the second slot 301 is located in the guide groove 3003. The auxiliary insert plate 4 is aligned with the second slot 301 through the guide groove 3003, so that the auxiliary insert plate 4 can be easily inserted into the second slot 301.

[0129] Specifically, the guide plate assembly 3002 includes two guide plates 30021, both of which are parallel to the auxiliary insert plate 4, and the two guide plates 30021 are respectively connected to the connecting block 30013, forming a guide groove 3003 between the two guide plates 30021.

[0130] The tops of both guide plates 30021 are sloped, which makes the width of the guide groove 3003 decrease from top to bottom in the left and right directions, thus making it easier to insert the auxiliary insert plate 4 into the guide groove 3003.

[0131] As one implementation, the insert plate installation tool 30 also includes a retaining plate 3004. The retaining plate 3004 is installed on the end of the guide plate assembly 3002 away from the connecting block 30013. A plurality of retaining posts 30041 are formed on the retaining plate 3004. The retaining posts 30041 are inserted into the guide groove 3003 from front to back, so that the dimensions of the guide groove 3003 in the left and right directions are consistent, which facilitates the insertion of the auxiliary insert plate 4 into the guide groove 3003.

[0132] Furthermore, the spacing between the retaining plate 3004 and the connecting block 30013 is consistent with the maximum length of the sub-insertion plate 4 in the front-back direction. The retaining plate 3004 and the connecting block 30013 are used to position the sub-insertion plate 4 in the front-back direction, thereby making it easier to insert the insertion part 401 into the second slot 301.

[0133] The steps for using the plug-in installation tool are as follows.

[0134] (1) Insert the main insert plate 2 into the needle plate body 1, and insert the insert plate mounting bracket 3 into the connecting groove 201 of the main insert plate 2;

[0135] (2) Connect the insert plate installation tool to the insert plate mounting bracket 3. When connecting, insert the positioning block 30012 into the second slot 301 at the leftmost or rightmost position of the insert plate mounting bracket 3, and ensure that the guide plate group 3002 is located between adjacent main insert plates 2.

[0136] (3) Insert the sub-insertion plate 4 into the guide groove 3003 to insert the insertion part 401 into the second slot 301 and complete the installation of the sub-insertion plate 4;

[0137] (4) Remove the retaining plate 3004 and then remove the mounting bracket 3001 from the needle plate body 1.

[0138] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
