Description

Technical Field

[0001] The invention relates to the field of polishing equipment, in particular to a device for polishing the rounded cutting surface of a knitting needle. Background Art

[0002] Knitting needles are the main parts of knitting machines, mainly used to weave yarns and make the yarns intertwined to form knitted fabrics. The structure and shape of knitting needles will directly affect the quality and production efficiency of knitted fabrics. Knitting needles are slender rod-shaped structures, and most of them are flat. When producing knitting needles, they will be separated from the raw materials by punching, so burrs are easily generated at the edges and corners. In order to prevent the knitting needles from hooking or cutting the threads when working, the surface of the knitting needles needs to be polished during production to remove the burrs and flash at the edges and corners of the knitting needles to improve the surface smoothness of the knitting needles.

[0003] Related technologies can refer to the Chinese patent with announcement number CN117921527B, which discloses a polishing device for grinding knitting needles, including a polishing outer barrel, which is composed of a barrel body and a cover plate, and the polishing outer barrel is injected with polishing liquid for grinding and polishing; and also includes: a supporting roller, which is arranged at the lower end of the cover plate constituting the polishing outer barrel, and the supporting roller is mutually fitted with a fixed track. The polishing device for grinding knitting needles, through the meshing between gears, drives the knitting needles to rotate alternately forward and reverse, and stirs the polishing liquid at the same time, thereby increasing the impact force between the polishing liquid and the knitting needles, and while driving the knitting needles to rotate and the polishing liquid to stir, it can also drive the brush plate to rotate, which can not only prevent the filter holes opened on the filter plate from being blocked by impurities in the polishing liquid, but also brush the impurities to the right side of the filter plate for collection, so as to achieve the purpose of filtering the polishing liquid and reuse it, thereby increasing the effect of the polishing liquid.

[0004] In view of the above-mentioned related technologies, in order to improve the polishing efficiency of knitting needles, knitting needles are placed in batches in the first limiting plate. During the polishing process, the knitting needles and the polishing liquid are moved relative to each other by moving the permeable barrel and the stirring rod, and then the knitting needles are polished. However, due to the weight of the knitting needles themselves, the knitting needles in the first limiting plate will settle on the corresponding partition plate. Although the space in the first limiting plate is separated by setting the second limiting plate, the probability of knitting needles gathering can be reduced to a certain extent, for the knitting needles between adjacent first limiting plates, during the rotation of the permeable barrel, the knitting needles will still gather at the position close to the first limiting plate and the partition plate under the action of the resistance and inertia of the polishing liquid. For the accumulated knitting needles, the impact strength of the polishing liquid on the knitting needles in different accumulation positions is different. For example, the impact strength of the polishing liquid on the knitting needles on the outside of the accumulation is greater, and the impact strength of the polishing liquid on the knitting needles on the inside of the accumulation is lower. The impact strength of the polishing liquid is different, and the polishing degree of the knitting needles will be different, which will eventually affect the overall polishing quality of a single batch of knitting needles and the polishing quality. Summary of the invention

[0005] In order to improve the polishing quality of knitting needles, the present application provides a device for polishing the rounded cutting surface of knitting needles.

[0006] The present application provides a device for polishing the rounded cutting surface of a knitting needle, which adopts the following technical solution:

[0007] A device for polishing the rounded surface of a knitting needle punching includes a polishing cylinder, a polishing cavity for placing a polishing liquid, a driving mechanism for driving the polishing liquid to flow in the polishing cavity, and a mounting frame, which is located inside the polishing cylinder and performs vertical reciprocating motion inside the polishing cylinder. A plugging cover adapted to the polishing cavity is fixedly provided at the upper end of the mounting frame, and a plurality of supporting plates are provided along the circumferential direction of the mounting frame. When the supporting plates are located in the polishing cavity, the polishing cavity is divided into a plurality of independent chambers. The supporting plates have through-flow openings. Hole, the flow hole is used to connect two adjacent chambers, all independent chambers are provided with two clamping plates, the clamping plates correspond to the support plates one by one, when polishing the knitting needle, the knitting needle is placed between the two clamping plates, all support plates are provided with elastic parts, the elastic parts are used to push the two clamping plates closer to each other, the end surface of the clamping plate in contact with the knitting needle is the abutment surface, when the abutment surface is in contact with the knitting needle, all corners of the knitting needle are exposed in the polishing chamber, the polishing cylinder is also provided with a positioning piece, after the clamping plate clamps the knitting needle, the positioning piece is used to fix the clamping plate.

[0008] By adopting the above technical solution, in the initial state, the mounting frame and the plug cover are both located at the upper end of the polishing cylinder. Before polishing, the knitting needle is placed between the two clamping plates between any two adjacent support plates. Under the action of the elastic member, the two clamping plates cooperate with each other to clamp the knitting needle, and the abutment surface is in the middle position of the largest end surface of the knitting needle. The mounting frame is placed in the polishing cylinder. At this time, the support plate and the corresponding knitting needle are both in the polishing cavity. The clamping plate is positioned by the positioning member to improve the clamping stability of the knitting needle. After the support plate enters the polishing cavity, the polishing cavity is divided into multiple independent chambers. Each knitting needle is in an independent chamber without interfering with each other. At this time, the flow holes connect the various chambers to each other. When the driving mechanism drives the polishing liquid to flow along the polishing cavity, the polishing liquid flows through all the chambers along the flow holes in turn, so that the edges and corners of the knitting needle are polished when the polishing liquid flows. At the same time, since the contact area between the clamping plate and the knitting needle is smaller than the maximum end face of the knitting needle, all the edges and corners of the knitting needle that need to be polished can be exposed in the polishing liquid and fully contact with the polishing liquid, and finally the purpose of polishing each corner of the knitting needle with the polishing liquid is achieved. During the polishing process, the knitting needle is in a stationary state, and each knitting needle is independent of each other, which is conducive to improving the polishing effect of the knitting needle and improving the polishing quality.

[0009] Optionally, a support portion is provided in the flow hole, the support portion is vertically arranged and fixedly connected to the support plate, sleeves are fixedly provided on both sides of the support portion along the circumference of the polishing chamber, a clamping plate is provided at one end of the sleeve away from the support portion, the clamping plate is slidably connected to the sleeve along a direction approaching or away from the support plate, the elastic member is a thrust spring, the thrust spring is located in the sleeve, one end of the thrust spring is fixedly connected to the support portion, and the other end is fixedly connected to the clamping plate.

[0010] By adopting the above technical solution, the mounting frame supports the supporting part through the supporting plate, and the supporting part supports and guides the clamping plate through the sleeve, so that the thrust spring pushes the two clamping plates closer to each other in a natural state to achieve the clamping of the knitting needles. The supporting part is located in the middle position of the flow hole, so that the polishing liquid flows evenly from both sides of the knitting needles, thereby further improving the polishing uniformity of the knitting needles.

[0011] Optionally, the clamping plate includes a clamping portion and a connecting portion, the connecting portion is inserted into the sleeve and is slidably connected to the sleeve in a direction approaching or away from the support plate, the clamping portion is located on a side of the connecting portion away from the support plate and is detachably connected to the connecting portion, and the abutment surface is located on a side of the clamping portion away from the connecting portion.

[0012] By adopting the above technical solution, the clamping part and the connecting part can be detachably connected, which makes it easy to replace the clamping part after it is worn. At the same time, by replacing clamping parts of different sizes, it can be suitable for processing knitting needles of different sizes, thereby improving the applicability of the clamping part.

[0013] Optionally, the positioning piece corresponds to the clamping plate one by one, and the positioning piece includes a support rod and a stop block. One end of the support rod is rotatably connected to the connecting part along the vertical direction, and the other end is vertically hinged with a slider. The supporting part is vertically provided with a sliding groove adapted to the slider. The slider is located in the sliding groove and is slidably connected to the supporting part along the length direction of the sliding groove. A positioning port connected to the sliding groove is opened at the lower end of the supporting part, and the positioning port is located directly below the slider. The stop block is arranged in the polishing cavity and directly opposite to the positioning port.

[0014] By adopting the above technical solution, under the cooperation of the slider and the slide groove, the connection part moves to drive the support rod to move. When the support plate enters the polishing cavity, the positioning block passes through the positioning port and enters the slide groove. When the positioning block contacts the slider, the slider is limited, and then the movement of the connection part is limited by the slider to realize the positioning of the clamping plate.

[0015] Optionally, the polishing cylinder is provided with a movable groove connected to the polishing chamber, the lower end of the stop block is located in the movable groove and is vertically slidably connected to the inner wall of the movable groove, the lower end of the polishing cylinder is rotatably connected to an adjusting screw, the adjusting screw passes through the polishing cylinder and is threadedly connected to the stop block.

[0016] By adopting the above technical solution, the polishing cylinder limits and guides the stop block through the movable groove. When the adjusting screw is rotated, the adjusting screw drives the stop block to move vertically, thereby facilitating the adjustment of the height of the stop block and the position of the clamping block.

[0017] Optionally, a support shaft is fixedly provided at the lower end of the blocking cover, the support shaft passes through the mounting frame, and the mounting frame is rotatably connected to the support shaft with the support shaft as the center.

The mounting shaft is provided with a rotating member for driving the mounting frame to rotate. A loading member is provided at the upper end of the blocking cover, and the loading member is used to place knitting needles between two adjacent support plates.

[0018] By adopting the above technical solution, the polishing cylinder drives the support shaft to move through the lifting member, and the support shaft drives the blocking cover and the mounting frame to move when it moves, so that it is convenient to move the mounting frame out of the polishing cylinder, and then it is convenient to place or take the knitting needles between two adjacent clamping plates. At the same time, when the rotating member drives the mounting frame to rotate, the mounting frame drives all the knitting needles to move at the same time, which is conducive to further improving the convenience of placing or removing the knitting needles.

[0019] Optionally, the feeding part includes a feeding box, a pushing plate and an extrusion block. The feeding box is located at the upper end of the blocking cover, and a storage cavity is opened in the feeding box in the transverse direction. The pushing plate is located in the storage cavity and is slidably connected to the feeding box along the length direction of the storage cavity. A feeding port adapted to the knitting needle is opened at the lower end of the feeding box, and the feeding port is connected with the storage cavity. A pushing spring is provided between the pushing plate and the feeding box, and the pushing spring is used to drive the pushing plate to move toward the feeding port. The extrusion block is located directly above the feeding port and is slidably connected with the feeding box along the vertical direction. A pushing plate is fixedly provided at the lower end of the extrusion block, and the thickness of the pushing plate is less than the thickness of the knitting needle. A feeding port adapted to the feeding port is opened at the upper end of the blocking cover. When the feeding port is connected with the feeding port, the pushing plate is directly opposite to the gap between any adjacent clamping plates.

[0020] By adopting the above technical scheme, in the initial state, the feeding port of the loading box is opposite to the feeding port of the blocking cover. At this time, the feeding port is opposite to the gap between any two adjacent clamping plates, multiple knitting needles are placed in the storage cavity, and the knitting needles are placed on the side of the pushing plate close to the feeding port. Under the action of the pushing spring, the pushing plate cooperates with the inner wall of the storage cavity to clamp all the knitting needles, and the storage cavity limits and guides the knitting needles. Initially, the extrusion block and the push plate are both above the knitting needles, and the pushing plate is driven by the extrusion block to move toward the feeding port. When the push plate moves, the knitting needle farthest from the pushing plate is pushed out from the feeding port, and the knitting needle passes through the feeding port and the feeding port in turn, and enters between the two adjacent clamping plates, thereby completing the loading of the knitting needle. When the loading of one knitting needle is completed, the rotating member drives the mounting frame to rotate, so as to facilitate the loading of another knitting needle between the two adjacent support plates, which is conducive to improving the convenience of placing the knitting needle.

[0021] Optionally, the mounting frame is vertically slidably connected with a pushing tube, a butt ring is fixedly provided at the lower end of the pushing tube, a reset piece is provided between the pushing tube and the mounting frame, when the pushing tube and the mounting frame produce relative displacement, the reset piece drives the pushing tube to reset, the butt ring is located below the polishing cylinder, the pushing tube is circumferentially provided with a plurality of moving rods corresponding to the support plate one by one, and all the moving rods are vertically hinged to the pushing tube, and one end of the moving rod away from the pushing tube is vertically hinged to a limit plate, the limit plate passes through the mounting frame horizontally and is slidably connected to the mounting frame, and when the two clamping plates clamp the knitting needles, the limit plate is directly below the knitting needles.

[0022] By adopting the above technical solution, in the initial state, the mounting frame is located in the polishing cylinder. Under the action of the reset member, the abutment ring is in a position away from the polishing cylinder, and all the limit plates are in a position close to the pushing tube. The moving rod is inclined from top to bottom along the direction of the pushing tube to the limit plate. When the knitting needle needs to be placed, the mounting frame is driven up by the lifting member, so that the mounting frame drives the pushing tube to move. After the pushing tube drives the abutment ring to contact the polishing cylinder, the mounting frame continues to rise. At this time, the pushing tube and the mounting frame produce a relative displacement in the vertical direction. When the pushing tube moves, the limit plate is driven to move by the moving rod, so that the limit plate is away from the supporting shaft. When the limit plate moves to below the clamping part, the mounting frame stops rising. The limit plate is used to limit the knitting needle, which is beneficial to reduce the probability of the knitting needle being placed at an angle.

[0023] Optionally, the polishing cylinder is provided with a plurality of positioning blocks along the circumference, the positioning blocks are spaced apart from the support plate, and are slidably connected to the polishing cylinder along the diameter direction of the polishing cylinder. When the support plate is located in the polishing cavity, the positioning blocks are located on the side of the clamping plate away from the axis of the mounting frame. A return spring is provided between the positioning block and the polishing cylinder, and the return spring is used to drive the positioning block away from the clamping plate. The blocking cover is provided with a moving part, and the moving part is used to drive the positioning block to approach the axis center of the mounting frame.

[0024] By adopting the above technical scheme, in the initial state, the positioning block is away from the clamping plate under the action of the return spring. After the knitting needle is clamped by the clamping plate, the mounting frame is driven to drive the knitting needle to move toward the polishing chamber. When the mounting frame drives the knitting needle into the polishing chamber, the knitting needle is in a position where the positioning block is away from the axis of the mounting frame. The blocking cover drives the positioning block close to the knitting needle through the moving part. After the positioning block contacts the knitting needle, the position of the knitting needle is corrected. When the knitting needle completely enters the polishing chamber, the positioning block is reset under the action of the return spring. The positioning block corrects the knitting needle, which is beneficial to reduce the probability of the knitting needle shifting laterally.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. In the initial state, the mounting frame and the plug cover are both located at the upper end of the polishing cylinder. Before polishing, the knitting needle is placed between the two clamping plates between any two adjacent support plates. Under the action of the elastic member, the two clamping plates cooperate with each other to clamp the knitting needle, and the abutment surface is in the middle position of the largest end surface of the knitting needle. The mounting frame is placed in the polishing cylinder. At this time, the support plate and the corresponding knitting needle are both in the polishing cavity. The clamping plate is positioned by the positioning member to improve the clamping stability of the knitting needle. After the support plate enters the polishing cavity, it divides the polishing cavity into multiple independent chambers. Each knitting needle is in an independent chamber without interfering with each other. At this time, the flow holes connect the various chambers to each other. When the driving mechanism drives the polishing liquid to flow along the polishing cavity, the polishing liquid flows through all the chambers along the flow holes in turn, so that the edges and corners of the knitting needle are polished when the polishing liquid flows. At the same time, since the contact surface area between the clamping plate and the knitting needle is smaller than the maximum end surface of the knitting needle, all the corners of the knitting needle that need to be polished can be exposed in the polishing liquid and fully contact with the polishing liquid, and finally the purpose of polishing each corner of the knitting needle with the polishing liquid is achieved. During the polishing process, the knitting needle is in a stationary state, and each knitting needle is independent of each other, which is conducive to improving the polishing effect of the knitting needle and improving the polishing quality;

[0027] 2. In the initial state, the positioning block is away from the clamping plate under the action of the return spring. After the knitting needle is clamped by the clamping plate, the mounting frame is driven to drive the knitting needle to move toward the polishing chamber. When the mounting frame drives the knitting needle into the polishing chamber, the knitting needle is in a position where the positioning block is away from the axis of the mounting frame. The blocking cover drives the positioning block close to the knitting needle through the moving part. After the positioning block contacts the knitting needle, the position of the knitting needle is corrected. When the knitting needle completely enters the polishing chamber, the positioning block is reset under the action of the return spring. The positioning block corrects the knitting needle, which is beneficial to reduce the probability of the knitting needle shifting laterally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0036] The embodiment of the present application discloses a device for polishing the rounded and cut surface of a knitting needle. Example

[0037] Reference Figure 1 and Figure 2 A device for polishing the rounded surface of a knitting needle punching includes a polishing cylinder 1 and a mounting frame 3. The polishing cylinder 1 is cylindrical and has a polishing cavity 11 formed in the circumferential direction. The mounting frame 3 is located inside the polishing cylinder 1 and is coaxially arranged with the polishing cylinder 1. A plug cover 4 is coaxially arranged on the upper end of the mounting frame 3, and a support shaft 41 is coaxially fixed on the lower end of the plug cover 4. The support shaft 41 passes through the mounting frame 3 and is coaxially rotatably connected with the mounting frame 3.

[0038] Reference Figure 2 and Figure 3 The mounting frame 3 includes an inner ring 31, an outer ring 32 and a plurality of connecting plates 33. The inner ring 31 is sleeved on the outside of the support shaft 41 and is rotatably connected to the support shaft 41 with the support shaft 41 as the center. The outer ring 32 is sleeved on the outside of the inner ring 31 and is coaxial with the inner ring 31. A plurality of connecting plates 33 are fixed between the inner ring 31 and the outer ring 32. The inner ring 31 is connected to the outer ring 32 through the connecting plates 33, so that when the inner ring 31 moves, the outer ring 32 is driven to move, and when the support shaft 41 moves along the axial direction, the mounting frame 3 is driven to move synchronously.

[0039] Reference Figure 1 and Figure 4The outer ring 32 is fixedly connected to a plurality of uniformly arranged support plates 5 along the circumferential direction. When the outer ring 32 moves, the support plates 5 are driven to move. A lifting member 14 is installed at the lower end of the polishing cylinder 1. The lifting member 14 is used to drive the support shaft 41 to move along the axial direction. The lifting member 14 uses a common mechanism in the technical field, such as a cylinder, a hydraulic cylinder, a motor screw, etc. In this embodiment, an electric push rod is used. When the lower end of the inner ring 31 contacts the inner wall of the polishing cavity 11, the lower end of the plugging cover 4 fits with the upper end of the polishing cylinder 1. At this time, the plugging cover 4, the polishing cylinder 1 and the outer ring 32 cooperate to form an annular cavity.

[0040] Reference Figure 1 The support shaft 41 is provided with a rotating member 42, which includes a rotating motor and an intermittent wheel set. The rotating motor is fixedly connected to the support shaft 41. When the support shaft 41 moves, the rotating motor is driven to move. The intermittent wheel set is located between the rotating motor and the inner ring 31. When the rotating motor is working, the intermittent wheel set drives the mounting frame 3 to rotate intermittently. The intermittent wheel set is a prior art, so it is not described in detail here. When the mounting frame 3 rotates intermittently, the moving angle of each rotation corresponds to the angle between the two adjacent support plates 5.

[0041] Reference Figure 1 and Figure 2 The mounting frame 3 is also connected with a push tube 7 in a vertical sliding manner. The push tube 7 is sleeved on the outside of the inner ring 31 and is coaxially arranged with the inner ring 31. An abutment ring 71 is fixedly arranged at the lower end of the push tube 7. When the push tube 7 moves, the abutment ring 71 is driven to move. A reset member 72 is arranged between the inner ring 31 and the push tube 7. The reset member 72 is a spring. One end of the spring is fixedly connected to the push tube 7, and the other end is fixedly connected to the mounting frame 3. When the reset member 72 is in a natural state, the abutment ring 71 is located close to the plugging cover 4. The push tube 7 is provided with a plurality of moving rods 73 corresponding to the support plates 5 in a one-to-one manner along the circumferential direction. The moving rods 73 are arranged at intervals with the support plates 5, and all the moving rods 73 are hinged to the push tube 7 in the vertical direction. When the push tube 7 moves, the moving rods 73 are driven to move.

[0042] Reference Figure 1 and Figure 2A limit plate 74 is provided between two adjacent support plates 5. The limit plate 74 is slidably connected with the outer ring 32 along the diameter direction of the outer ring 32. The outer ring 32 is provided with a through slot for the limit plate 74 to pass through. The limit plate 74 passes through the through slot and fits with the inner wall of the through slot. The moving rod 73 corresponds to the limit plate 74 one by one, and the moving rod 73 is hinged with the limit plate 74 along the vertical direction. The moving rod 73 is tilted from top to bottom along the direction of the support shaft 41 pointing to the limit plate 74. When the push tube 7 moves away from the mounting frame 3 vertically, the moving rod 73 pushes the limit plate 74 to move in the direction away from the support shaft 41. Under the action of the reset member 72, the push tube 7 is located near the blocking cover 4 in the initial state. At this time, the limit plate 74 is located in the through slot, and the end of the limit plate 74 away from the support shaft 41 is flush with the outer edge of the outer ring 32.

[0043] Reference Figure 4 and Figure 5 , all the support plates 5 are provided with flow holes 51 along the circumference of the outer ring 32, and a support portion 52 is vertically arranged in the flow hole 51, the support portion 52 is fixedly connected to the support plate 5, and the support portion 52 is driven to move when the support plate 5 moves. Both sides of the support portion 52 are fixedly provided with a sleeve pipe 53, and the sleeve pipe 53 is vertically arranged with the support plate 5. A clamping plate 54 is provided at one end of the sleeve pipe 53 away from the support portion 52, and the clamping plate 54 includes a clamping portion 541 and a connecting portion 542, and the connecting portion 542 is inserted into the sleeve pipe 53 and slidably connected with the sleeve pipe 53 in the direction of approaching or moving away from the support plate 5. A card slot is vertically opened at one end of the connecting portion 542 away from the sleeve pipe 53, and a card block adapted to the card slot is fixedly provided on the clamping portion 541, and the card block is located in the card slot and is clamped with the connecting portion 542. The clamping portion 541 and the connecting portion 542 are detachably connected, which is conducive to improving the convenience of replacing the clamping portion 541.

[0044] Reference Figure 4 and Figure 5 The support plate 5 is provided with an elastic member corresponding to the clamping plate 54. The elastic member is a thrust spring 55. The thrust spring 55 is located in the sleeve tube 53, and one end of the thrust spring 55 is fixedly connected to the support portion 52, and the other end is fixedly connected to the connecting portion 542. The thrust spring 55 is in a compressed state, and then pushes the connecting portion 542 in a direction away from the support portion 52. The end surface of the clamping plate 54 away from the connecting portion 542 is set as a contact surface. In this embodiment, the contact surface of the clamping portion 541 is set according to the end surface of the processed knitting needle, and the width and length of the contact surface are both less than the length and width of the maximum end surface of the knitting needle. The two clamping plates 54 between two adjacent support plates 5 are set as the same clamping group. Under the action of the thrust spring 55, the two clamping plates 54 in the same clamping group are close to each other, and the contact surfaces of the two clamping portions 541 are in contact with each other.

[0045] Reference Figure 1 and Figure 2When the knitting needles need to be placed, the mounting frame 3 and the blocking cover 4 are moved upward by the lifting member 14. When the abutting ring 71 contacts the lower end of the polishing cylinder 1, the abutting tube and the mounting frame 3 are relatively displaced when the mounting frame 3 continues to move, so that the reset member 72 is gradually deformed. At this time, the abutting tube drives the limit plate 74 away from the support shaft 41 through the moving rod 73, so that the limit plate 74 moves out of the through slot. At this time, the limit plate 74 moves out of the through slot and is located below the clamping plate 54.

[0046] Reference Figure 2 and Figure 6 The plugging cover 4 is provided with a feed port 44 in the vertical direction. When the mounting frame 3 and the plugging cover 4 are in a relatively static state, the feed port 44 always corresponds to any clamping group. A feeding member 43 is provided at the upper end of the plugging cover 4. The feeding member 43 includes a feeding box 431, a pushing plate 432 and an extrusion block 433. The feeding box 431 is provided with a storage cavity 434 in the horizontal direction. The width of the storage cavity 434 is adapted to the width of the knitting needle. The pushing plate 432 is located in the storage cavity 434 and is slidably connected with the pushing plate 432 in the horizontal direction. When the feeding box 431 moves, the pushing plate 432 is driven to move synchronously.

[0047] Reference Figure 2 and Figure 6 A push spring 436 is provided at one end of the material storage chamber 434 along the length direction, one end of the push spring 436 is fixedly connected to the material loading box 431, and the other end is fixedly connected to the material pushing plate 432. A material discharge port 435 is opened at one end of the material loading box 431 away from the push spring 436, and the material discharge port 435 is connected to the material storage chamber 434, and the side of the material discharge port 435 away from the push spring 436 is flush with the inner wall of the material storage chamber 434. The push spring 436 is in a compressed state, and applies a thrust to the material pushing plate 432 to approach the material discharge port 435.

[0048] Reference Figure 2 and Figure 6 , multiple knitting needles are placed in the material storage chamber 434, and the knitting needles are located at one end of the push plate 432 close to the discharge port 435. Under the action of the push spring 436, the push plate 432 cooperates with the inner wall of the material storage chamber 434 to clamp all the knitting needles. During this process, the inner wall of the material storage chamber 434 limits the knitting needles, so that all the knitting needles in the material storage chamber 434 are in the same straight line. The extrusion block 433 is located at the upper end of the discharge port 435, and is vertically slidably connected to the loading box 431. When the knitting needles are placed in the material storage chamber 434, the extrusion block 433 is initially located on the side of the knitting needles away from the blocking cover 4. A push plate 437 is fixed at the lower end of the extrusion block 433. When the knitting needles are located in the material storage chamber 434, the push plate 437 is parallel to the knitting needles, and the thickness of the push plate 437 is lower than the thickness of the knitting needles.

[0049] Reference Figure 2 and Figure 6, a clamping block is fixedly arranged at the lower end of the loading box 431, and a docking groove corresponding to the clamping block is opened at the upper end of the blocking cover 4. When the clamping block is inserted into the docking groove, the unloading port 435 is directly opposite to the feeding port 44, and the width of the unloading port 435 is greater than the thickness of a single knitting needle and less than the thickness of two knitting needles stacked together. When the knitting needle needs to be placed, the extrusion block 433 is pressed toward the blocking cover 4, and the extrusion block 433 drives the knitting needle farthest from the pushing plate 432 through the pushing plate 437 in turn through the unloading port 435 and the feeding port 44, and enters the two clamping parts 541 in the same clamping group (refer to Figure 4 ) between the two clamping parts 541 (reference Figure 4 ) cooperates to clamp the knitting needles. During this process, the limiting plate 74 limits the vertical height of the knitting needles to improve the placement stability of the knitting needles.

[0050] Reference Figure 2 and Figure 6 After one knitting needle is loaded, the extrusion block 433 is reset, and under the action of the push spring 436, the push plate 432 drives the remaining knitting needles to continue to move above the lower feed port 435. Figure 1 ) drives the mounting frame 3 to rotate, so that another clamping group moves to the bottom of the feeding port 435, repeats the above operation, and then completes the placement of all the knitting needles, which is conducive to improving the convenience of placing the knitting needles. When placing the knitting needles, the limiting plate 74 limits the height of the knitting needles in the vertical direction, which is conducive to improving the placement stability of the knitting needles.

[0051] Reference Figure 2 and Figure 4 When all the knitting needles are placed in the clamping groups between the adjacent support plates 5, the lifting member 14 is operated to drive the mounting frame 3 and the plug cover 4 to move toward the polishing cylinder 1. At this time, the push tube 7 is relatively displaced with the inner ring 31 again under the action of the reset member 72, so that the moving rod 73 drives the limit plate 74 to reset. The polishing cylinder 1 is provided with a positioning member, which corresponds to the clamping plate 54 one by one. The positioning member includes a support rod 61 and a stop block 62. The support rod 61 is located in the support sleeve and is located on the side of the connecting portion 542 away from the clamping portion 541. The support rod 61 is hinged with the connecting portion 542 in the vertical direction. When the connecting portion 542 moves, the support rod 61 is driven to move.

[0052] Reference Figure 3 and Figure 5The end of the support rod 61 away from the connection part 542 is vertically hinged with a slider 611, and the support part 52 is vertically provided with a slide groove 521. The slider 611 is located in the slide groove 521 and is slidably connected with the support part 52 along the length direction of the slide groove 521. The support part 52 limits the slider 611 through the slide groove 521, so that when the support rod 61 moves, the slider 611 is driven to move along the slide groove 521. The support rod 61 is tilted from top to bottom along the direction from the connection part 542 to the support part 52. When the connection block approaches the support part 52, the support rod 61 pushes the slider 611 to move in the direction away from the blocking cover 4.

[0053] Reference Figure 3 and Figure 5 All the stop blocks 62 are located in the polishing cavity 11. The polishing cylinder 1 is provided with a moving groove 12 connected to the polishing cylinder 1. The lower end of the stop block 62 is located in the moving groove 12 and is vertically slidably connected to the polishing cylinder 1. The polishing cylinder 1 limits the lateral displacement of the stop block 62 through the moving groove 12. The lower end of the support portion 52 is provided with a positioning port 522 connected to the slide slot 521. The positioning port 522 corresponds to the stop block 62 one by one. When the mounting frame 3 and the plug cover 4 are in a relatively static state, all the positioning ports 522 are directly above the stop block 62.

[0054] Reference Figure 3 and Figure 5 , when mounting bracket 3 (reference Figure 2 ) After the support plate 5 is driven to completely enter the polishing chamber 11, the stop block 62 enters the corresponding positioning port 522 and contacts the lower end of the slider 611. When the stop block 62 contacts the slider 611, the displacement of the slider 611 away from the blocking cover 4 is limited. Under the support of the support rod 61, the displacement of the connecting portion 542 close to the support portion 52 is limited, which is beneficial to reduce the probability of the clamping portion 541 being separated from the knitting needles and improve the clamping effect of the clamping plate 54 on the knitting needles. The lower end of the polishing cylinder 1 is rotatably connected with an adjusting screw 13, and the upper end of the adjusting screw 13 is located in the stop block 62 and is threadedly connected to the stop block 62. Under the limiting effect of the movable groove 12, the adjusting screw 13 drives the stop block 62 to move vertically when it rotates, thereby facilitating the adjustment of the height of the stop block 62, so that the clamping plate 54 is suitable for clamping knitting needles of different thicknesses, thereby improving the applicability of the clamping plate 54.

[0055] Reference Figure 2 and Figure 3A sealing ring 16 is coaxially fixed on the side of the polishing cylinder 1 close to the support shaft 41. When the plugging cover 4 seals the polishing cavity 11, the lower end of the outer ring 32 contacts and fits with the upper end of the sealing ring 16. The polishing cylinder 1 is also fixed with a support ring 17, which is located on the side of the sealing ring 16 away from the support shaft 41, and the support ring 17 is coaxially arranged with the sealing ring 16. A sealing ring 321 is fixed on the lower end of the outer ring 32, and the sealing ring 321 is located between the sealing ring 16 and the support ring 17, and fits with the sealing ring 16 and the support ring 17 to improve the airtightness between the inner ring 31 and the inner wall of the polishing cavity 11.

[0056] Reference Figure 2 and Figure 3 The polishing cylinder 1 is provided with a plurality of positioning blocks 8 along the circumferential direction. The positioning blocks 8 correspond to the support plates 5 one by one. All the positioning blocks 8 are located in the polishing cavity 11. A straight rod 81 is fixedly provided on the upper end of the positioning block 8. The straight rod 81 is slidably connected to the polishing cylinder 1 along the diameter direction of the polishing cylinder 1. A driving block 82 is fixedly provided at one end of the straight rod 81 away from the positioning block 8. The driving block 82 is arranged along an arc from top to bottom. The polishing cylinder 1 is provided with a receiving groove for placing the driving block 82. A return spring 15 is provided between the driving block 82 and the polishing cylinder 1. One end of the return spring 15 is fixedly connected to the driving block 82, and the other end is fixedly connected to the polishing cylinder 1. The return spring 15 is in a compressed state and has a tendency to push the positioning block 8 away from the support shaft 41.

[0057] Reference Figure 2 and Figure 3 The lower end of the blocking cover 4 is fixed with a moving member 9, which includes a circular ring block 91 and a pushing block 92. The circular ring block 91 is coaxially fixed to the lower end of the blocking cover 4 and is arranged along the circumference of the blocking cover 4. The pushing block 92 is fixed to one side of the circular ring block 91 close to the support shaft 41. When the outer ring 32 is close to the blocking ring 16, the circular ring block 91 drives the pushing block 92 to approach the driving block 82. When the pushing block 92 contacts the driving block 82, the driving block 82 is pushed to approach the support shaft 41. When the driving block 82 moves, it drives the positioning block 8 to approach the knitting needle through the straight rod 81.

[0058] Reference Figure 1 and Figure 2 In the initial state, when the knitting needle is placed between the two clamping plates 54 of the same clamping group, the knitting needle is at a position away from the support shaft 41. When the positioning block 8 contacts the knitting needle and pushes the knitting needle to approach the support shaft 41, when the driving block 82 moves to the closest point to the support shaft 41, the positioning block 8 and the knitting needle push the knitting needle to move to a predetermined position, and the clamping portion 541 (reference Figure 4 ) is located at the middle of the largest end face of the knitting needle, so that the corners of the knitting needle are exposed to the clamping portion 541 (reference Figure 4 )outside.

[0059] Reference Figure 1 and Figure 2 The polishing cylinder 1 is provided with a driving mechanism, which includes a liquid tank 21, a liquid infusion tube 22, a recovery tube 23 and a driving pump 24. Polishing liquid is stored in the liquid tank 21. The liquid infusion tube 22 and the recovery tube 23 are both connected to the liquid tank 21, and the ends of the liquid infusion tube 22 and the recovery tube 23 away from the liquid tank 21 are both connected to the polishing cylinder 1. Among all the support plates 5, any one of the support plates 5 is set as a baffle plate, and the baffle plate does not have a flow hole 51. When the support plate 5 is located in the polishing cavity 11, the liquid infusion tube 22 and the recovery tube 23 are respectively located on both sides of the baffle plate, thereby making the polishing cavity 11 unidirectionally connected. The driving pump 24 is connected to the infusion tube 22. When the driving pump 24 is working, the polishing liquid is input into the polishing chamber 11 through the infusion tube 22. Under the action of the polishing cylinder 1, the support ring 17, the outer ring 32 and the plugging cover 4, the polishing liquid passes through all the flow holes 51 in turn and flows back to the liquid tank 21 through the recovery tube 23. When the polishing liquid flows, the knitting needles between the adjacent support plates 5 are polished.

[0060] The implementation principle of the device for polishing the rounded blanking surface of a knitting needle in the embodiment of the present application is as follows: under the action of the thrust spring 55, the two clamping plates 54 in the same clamping group cooperate to clamp and position the knitting needles, and in the process of clamping the knitting needles, the vertical height of the knitting needles is limited by the limit plate 74, so that all the knitting needles are in the same plane. After the knitting needles enter the polishing cavity 11, the position of the knitting needles is adjusted by the positioning block 8, so that the contact surface of the clamping part 541 is in the middle position of the largest end face of the knitting needles. Under the guiding action of the support plate 5, when the polishing liquid flows along the polishing cavity 11, the edges and corners of the knitting needles are exposed to the polishing liquid and fully contact the polishing liquid. All the knitting needles are placed independently, and the knitting needles are in a positioned state during polishing, which is conducive to improving the polishing effect of the knitting needles and improving the polishing quality.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
