Description

Technical Field

[0001] The invention relates to the technical field of wire winding, and in particular to an adjustable automatic winding machine. Background Art

[0002] The automatic winding machine is a kind of equipment used in the textile industry. It is mainly used to connect tubes of yarn with smaller capacity to make larger bobbins to improve subsequent production efficiency and production quality. When the winding amount on the bobbin reaches the requirement, it is necessary to replace the new bobbin and collect the old one. Manual disassembly and assembly of the bobbin is inefficient.

[0003] The patent application document with publication number CN116675059A discloses an automatic spinning winder, including a grooved drum installed at the upper ends of a left column and a right column, a bobbin is arranged at the upper end of the grooved drum, a left plugging column and a right plugging column are respectively arranged at the upper ends of the left column and the right column, the right plugging column is connected to the output shaft of the first motor, the left plugging column is connected to the driving mechanism through an inverted L-shaped support rod, the driving mechanism can drive the inverted L-shaped support rod to move to the left, a first pushing mechanism for pushing the bobbin to the left is arranged at the upper end of the right column, the first pushing mechanism is connected to the driving mechanism through a first linkage mechanism; a second pushing mechanism for pushing the bobbin forward is arranged at the upper end of the inverted L-shaped support rod, the second pushing mechanism is connected to the inverted L-shaped support rod through a guide mechanism, and a collecting device is arranged on the front side of the left column and the right column; the winder provided by the patent application document realizes the purpose of disassembling and collecting the bobbin by operating the driving mechanism, and there is no need to manually pick up the heavier bobbin, which saves manpower and improves the work efficiency of workers.

[0004] In order to adapt to the requirements of winding density and shape of yarns of different materials (such as cotton, wool, silk or various blended yarns), as well as the requirements of subsequent textile processes (such as dyeing, manufacturing or knitting), to ensure the uniformity of the yarn and the smoothness of subsequent processing, the self-winding machine often needs to wind the yarn on bobbins of different sizes and shapes according to processing needs; the winding machine provided by the above-mentioned patent document inserts the left and right plug-in columns into the two ends of the bobbin to clamp and fix the bobbin. During the production process, if different models of bobbins are replaced, in order to adapt to the shape and size of the bobbin, it is necessary to stop the machine and replace the corresponding accessories for fixing the bobbin. The patent document fixes the bobbin by means of the left and right plug-in columns being relatively close to the clamping bobbin. If the clamping force is too small, the bobbin will become loose, and if the clamping force is too large, the bobbin will be squeezed to a certain extent in its axial direction, resulting in deformation or damage. Too large or too small a clamping force can easily affect the winding quality and forming of the wire material. Summary of the invention

[0005] The present invention provides an adjustable automatic winding machine, aiming to solve the problems in the related art that the winding machine is inconvenient to clamp different types of wire bobbins, and when clamping the wire bobbins, the wire bobbins are easily loosened or deformed due to the clamping force, thus affecting the winding quality of the wire material.

[0006] An adjustable automatic winding machine of the present invention comprises a frame, the frame is provided with a grooved drum for guiding a wire material, the frame is also provided with a fixing mechanism for fixing a wire bobbin, the fixing mechanism comprises a connecting member, a driving member, a clamping assembly and an adjusting assembly;

[0007] The driving member drives the connecting member to rotate and cooperate with the frame, the rotation center of the connecting member is parallel to the rotation center of the groove drum, the connecting member is provided with two opposite connecting parts, the clamping assembly has two groups, and the two groups of clamping assemblies are respectively opposite to the axial ends of the wire drum, the clamping assembly includes a guide member, a movable member and a plurality of clamping members, with the side facing the wire drum as the inner side, the guide member is located on the inner side of the movable member, the guide member is rotationally cooperated with the connecting part, the movable member is slidingly cooperated with the connecting part, one end of the clamping member is hinged to the movable member, and the other end of the clamping member extends into the interior of the wire drum and abuts against the inner wall of the wire drum, the clamping member is slidingly cooperated with the guide member in its length direction, and the adjusting assembly is used to push the movable member to approach or move away from the guide member.

[0008] The beneficial effect is that it is convenient to clamp and fix the wire bobbins of different models. When the adjusting assembly pushes the movable part close to the guide part, the inner end of each clamping part moves away from the axial direction of the connecting part as the distance between the movable part and the guide part decreases. That is, when the adjusting assembly pushes the movable part close to the guide part, each clamping part moves inward and opens until the inner end of each clamping part abuts against the inner wall of the wire bobbin. When the fixing mechanism fixes the wire bobbin, each clamping part can automatically extend into the inside of the wire bobbin and abut against the inner wall of the wire bobbin to fix the wire bobbin.

[0009] In addition, compared with the method of clamping the wire bobbin by applying pressure from both ends of the wire bobbin in the related art, while ensuring the wire bobbin fixing effect, it also effectively avoids the squeezing effect on the wire bobbin in its axial direction, reduces the possibility of deformation during the wire bobbin fixing operation, and effectively improves the winding quality of the wire bobbin.

[0010] Preferably, the adjustment assembly includes a moving part, an adjusting part and an adjusting block, there are two moving parts, the two moving parts are "L" shaped, one end of the moving part slides with the adjusting part, the other end of the moving part slides with the connecting part and is elastically connected to the connecting part, the movable part rotates with the moving part, an adjustment groove is provided on the adjusting part, the adjustment block slides with the adjustment groove in a direction approaching or away from the wire drum, the width of the adjustment block increases in a direction away from the wire drum, and the adjustment block is also provided with a limiting structure for limiting its sliding relative to the adjustment groove.

[0011] Preferably, the limiting structure includes a limiting rod and a push rod, the limiting rod slidingly cooperates with the adjusting block at the wide end of the adjusting block, one end of the limiting rod is elastically connected to the adjusting block, a limiting groove is provided on the limiting rod, the push rod slidingly cooperates with the adjusting block in a direction approaching or moving away from the wire bobbin, the push rod is elastically connected to the adjusting block, the sliding direction of the limiting rod is perpendicular to the sliding direction of the limiting rod, one end of the push rod extends to the inner side of the adjusting block, and the other end of the push rod is movably connected to the limiting groove, and when the push rod is extended into the limiting groove, it pushes the limiting rod into the inner side of the adjusting block and releases the limiting of the adjusting block and the adjusting groove.

[0012] Preferably, a connecting rod is further provided at the wide end of the adjusting block, and elastic parts are respectively slidably connected at both ends of the connecting rod, and the two elastic parts are respectively slidably matched with the two moving parts, and when the connecting rod approaches the moving parts, the two elastic parts are squeezed to store force.

[0013] The beneficial effects are: simplifying the operation of fixing the wire bobbin. When fixing the wire bobbin, the staff holds the wire bobbin and places it between the two groups of clamping assemblies. The wire bobbin contacts the push rod and pushes the push rod to move in the direction away from the wire bobbin. When the push rod moves, it pushes the limit rod to be retracted into the adjusting block, and the limiting state between the adjusting block and the adjusting slot is released. Under the elastic force of the elastic member, the adjusting block slides quickly in the direction away from the wire bobbin, and at the same time, the two moving parts are relatively close to each other. When the two moving parts are close to each other, they push the clamping parts on the two groups of clamping assemblies to be relatively close and open. During the approaching and opening action, each clamping part extends into the two ends of the wire bobbin and abuts against the inner wall of the wire bobbin, thereby realizing rapid fixation of the wire bobbin and improving the fixing efficiency of the wire bobbin.

[0014] Preferably, a reset block is also provided on the frame, and the side of the reset block opposite to the wire drum is arc-shaped, and the arc-shaped side of the reset block is inclined from top to bottom in a direction close to the wire drum. When the driving member drives the connecting member to rotate in a direction close to the reset block, the reset block squeezes the adjusting block to move in a direction close to the wire drum.

[0015] The beneficial effects are: it is convenient to automatically unload the bobbin after the bobbin is wound; after the bobbin is wound, the driving member drives the fixing mechanism to rotate until the connecting rod abuts against the reset block; when the connecting rod slides relative to the reset block, the reset block squeezes the connecting rod and moves the adjusting block toward the bobbin; during this process, the adjusting block squeezes the two moving parts apart, drives the moving part away from the guide part, causes the clamping part to detach from the inside of the bobbin, and the bobbin falls onto the frame, saving manpower.

[0016] Preferably, the guide member is provided with a plurality of installation grooves corresponding to the clamping members one by one, a guide portion is provided in the installation groove, and the clamping member is provided with a guide groove in its length direction, and the guide groove is slidably matched with the guide portion.

[0017] Preferably, the guide portion slides with the mounting groove along the radial direction of the guide member, with the side facing the axial direction of the guide member as the front side, and the movable member is also connected with an adjustment portion, which is inserted into the mounting groove and abuts against the front side of the guide portion, and the width of the adjustment portion decreases in the direction away from the movable member, and the rear side of the guide portion is elastically connected to the mounting groove.

[0018] The beneficial effects are: the speed at which the clamping assembly fixes the wire bobbin is improved, the width of the adjusting portion decreases in the direction away from the movable part, and when the movable part approaches the guide part, the adjusting portion pushes the guide part to slide rearward at the same time. When the movable part moves a smaller distance, it can drive each clamping part to quickly open a larger angle, thereby realizing the rapid fixing operation of the wire bobbin.

[0019] Preferably, the inner end portion of each clamping member is rotatably connected to a guide wheel, and the guide wheel is in sliding contact with the inner wall of the wire barrel.

[0020] Preferably, the clamping members of the two groups of clamping assemblies have different lengths, and the clamping members of the same group of clamping assemblies have the same length.

[0021] The beneficial effect is that it is convenient to fix the conical wire bobbin, the clamping pieces of the two sets of clamping assemblies are set with different lengths, and the clamping piece with a longer length corresponds to the large end of the conical wire bobbin. When fixing the conical wire bobbin, it is convenient for the two sets of clamping assemblies to quickly fix the large end and the small end of the conical wire bobbin.

[0022] Preferably, the clamping members are evenly spaced around the circumference of the connecting portion.

[0023] The beneficial effects of the present invention are:

[0024] (1) It is convenient to clamp and fix bobbins of different models. When the adjusting assembly pushes the movable part to approach the guide part, the inner end of each clamping part moves away from the axial direction of the connecting part as the distance between the movable part and the guide part decreases. That is, when the adjusting assembly pushes the movable part to approach the guide part, each clamping part moves inward and opens until the inner end of each clamping part abuts against the inner wall of the bobbin. When the fixing mechanism fixes the bobbin, each clamping part can automatically extend into the inside of the bobbin and abut against the inner wall of the bobbin to fix the bobbin. Compared with the method of clamping the bobbin by applying pressure from both ends of the bobbin in the related art, while ensuring the fixing effect of the bobbin, it also effectively avoids the squeezing effect on the bobbin in its axial direction, reduces the possibility of deformation during the bobbin fixing operation, and effectively improves the winding quality of the bobbin.

[0025] (2) Simplify the operation of fixing the wire bobbin. When fixing the wire bobbin, the staff holds the wire bobbin and places it between the two groups of clamping assemblies. The wire bobbin contacts the push rod and pushes the push rod to move away from the wire bobbin. When the push rod moves, it pushes the limit rod back into the adjustment block, releasing the limit state between the adjustment block and the adjustment groove. Under the elastic force of the elastic member, the adjustment block slides quickly in the direction away from the wire bobbin. At the same time, the two moving parts are relatively close to each other. When the two moving parts are close to each other, they push the clamping parts on the two groups of clamping assemblies to be relatively close and open. During the action of approaching and opening, each clamping part extends into the two ends of the wire bobbin and abuts against the inner wall of the wire bobbin, thereby realizing rapid fixation of the wire bobbin and improving the fixing efficiency of the wire bobbin.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 3As shown, the adjustable automatic winding machine of the present invention comprises a frame 1, a groove drum 11 and a fixing mechanism are provided on the frame 1, the fixing mechanism is used to clamp and fix the bobbin 4, the groove drum 11 is provided with a wire groove 111, the frame 1 is also provided with a motor for driving the groove drum 11 to rotate, when the motor drives the groove drum 11 to rotate, the silk thread is guided to be wound around the bobbin 4, the fixing mechanism comprises a connecting member 2, a driving member, a clamping assembly and an adjusting assembly, the driving member comprises a driving shaft 121 and a driving source 12, the axial direction of the driving shaft 121 is parallel to the axial direction of the groove drum 11, the driving shaft 121 is rotatably matched with the frame 1, the driving end of the driving source 12 is fixed to one end of the driving shaft 121, the driving source 12 can be a motor, the connecting member 2 is fixed relative to the driving shaft 121, there are two groups of clamping assemblies, the two groups of clamping assemblies are arranged opposite to each other on the connecting member 2, and the adjusting assembly is used to adjust the two clamping assemblies to extend into the two ends of the bobbin 4 to fix the bobbin 4, or extend from the two ends of the bobbin 4 to detach from the bobbin 4.

[0036] The connecting member 2 is in a "U" shape, and the open end of the connecting member 2 is arranged away from the driving shaft 121. Two connecting parts 21 are oppositely provided at the open end of the connecting member 2. The connecting parts 21 can be rod-shaped. The two groups of clamping components are respectively installed on the two connecting parts 21, with the side facing the bobbin 4 as the inner side, and the adjusting component is slidably matched with the two connecting parts 21 on the outside of the two groups of clamping components at the same time.

[0037] like Figure 5 and Figure 6 As shown, the clamping assembly includes a guide member 23, a movable member 22 and a plurality of clamping members 24. The guide member 23 is located inside the movable member 22. The guide member 23 is rotatably matched with the connecting portion 21 at the inner end of the connecting portion 21. The movable member 22 is slidably matched with the connecting portion 21. Each clamping member 24 is evenly spaced around the circumference of the connecting portion 21. One end of the clamping member 24 is hinged to the movable member 22. The other end of the clamping member 24 is used to extend into the inside of the wire barrel 4 and abut against the inner wall of the wire barrel 4. The clamping member 24 is slidably matched with the guide member 23 in the length direction thereof.

[0038] A plurality of mounting grooves are provided on the guide member 23, and each mounting groove is arranged in a one-to-one correspondence with each clamping member 24. A guide portion 231 is provided in the mounting groove, and a guide groove 241 is provided in the length direction of the clamping member 24, and the guide groove 241 and the guide portion 231 are slidably matched. When the adjusting component pushes the movable member 22 to approach the guide member 23, the clamping member 24 slides relative to the guide portion 231, and the inner end portion of each clamping member 24 moves away from the axial direction of the connecting portion 21 as the distance between the movable member 22 and the guide member 23 decreases, that is, when the adjusting component pushes the movable member 22 to approach the guide member 23, each clamping member 24 moves inward and opens until the inner end portion of each clamping member 24 abuts against the inner wall of the wire reel 4.

[0039] In order to improve the speed of the clamping assembly to fix the wire barrel 4, so that each clamping member 24 can quickly abut against the inner wall of the wire barrel 4 and fix the wire barrel 4, the guide portion 231 can also slide with the installation groove. Specifically, the guide groove 241 slides with the installation groove along the radial direction of the guide member 23. The movable member 22 is also fixed with an adjusting portion 25, with the side facing the axial direction of the guide member 23 as its front side. The adjusting portion 25 is inserted into the installation groove and abuts against the front side of the guide portion 231. The width of the adjusting portion 25 decreases in the direction away from the movable member 22. When the movable member 22 approaches the guide member 23, the adjusting portion 25 pushes the guide member 23 at the same time. 1 slides to the rear side. Compared with the way that the guide part 231 is directly fixed on the installation groove, when the movable part 22 moves a smaller distance, it can drive each clamping part 24 to quickly open a larger angle, so as to realize the quick fixing operation of the wire barrel 4. A rod body and a spring are also provided in the installation groove. The rod body is arranged along the radial direction of the guide part 23 and slides with the guide part 23. The spring is sleeved on the rod body and abuts against the rear side end of the guide part 231. When the guide part 231 slides in the direction away from the axial direction of the guide part 23, the spring is squeezed and force is accumulated in the spring, so as to ensure that the guide part 231 is in a state of fitting the inclined surface side of the adjusting part 25.

[0040] like Figure 3 and Figure 4 As shown, the adjustment component includes a moving member 3, an adjustment member 31 and an adjustment block 32. There are two moving members 3, and the two moving members 3 are "L"-shaped. One end of the moving member 3 slides with the adjustment member 31, and the other end of the moving member 3 slides with the connecting portion 21 and is elastically connected to the connecting portion 21. The moving member 3 rotates with the movable member 22, and the movable member 22 slides synchronously with the moving member 3 on the connecting portion 21. The connecting portion 21 is provided with a spring on the outer side of the moving member 3, and the spring is in a compressed state. An adjustment groove is provided on the adjustment member 31, and the adjustment block 32 slides with the adjustment groove in a direction close to or away from the wire drum 4. The width of the adjustment block 32 increases in a direction away from the wire drum 4, and the two moving members 3 abut against the adjustment blocks 32. When the wide end of the adjusting block 32 is located in the adjusting groove, the distance between the two moving parts 3 is the largest. When the adjusting block 32 slides in the direction away from the bobbin 4, the width of the adjusting block 32 in the adjusting groove gradually becomes smaller, and the two moving parts 3 approach each other under the elastic force of the spring, and push the two movable parts 22 to move inward until the clamping assembly extends into the bobbin 4 to clamp and fix the bobbin 4. Similarly, when the adjusting block 32 slides in the direction close to the bobbin 4, the width of the adjusting block 32 in the adjusting groove increases, and the adjusting block 32 pushes the two moving parts 3 relatively away and squeezes the spring, and drives the clamping member 24 to withdraw and retract from the bobbin 4, releases the fixation of the bobbin 4, and makes the bobbin 4 that has been wound detached from the clamping assembly.

[0041] like Figure 1 and Figure 3As shown, the state where the wire bobbin 4 is not fixed on the fixing mechanism is its initial state. In order to keep the fixing mechanism in its initial state, it is convenient for the staff to place the wire bobbin 4 between the two clamping components, such as Figure 4 The cam 322 is provided with a limit structure for limiting its relative sliding movement in the adjustment slot, and the limit structure includes a limit rod 322 and a push rod 321. The limit rod 322 is slidably matched with the adjustment block 32 at the wide end of the adjustment block 32, and one end of the limit rod 322 is elastically connected to the adjustment block 32. A limit slot is provided on the limit rod 322. The push rod 321 is slidably matched with the adjustment block 32 in a direction close to or away from the bobbin 4. The push rod 321 is elastically connected to the adjustment block 32. The sliding direction of the limit rod 322 is perpendicular to the sliding direction of the limit rod 322. One end of the push rod 321 extends to the inner side of the adjustment block 32, and the other end of the push rod 321 is movably connected to the limit slot. When the push rod 321 extends into the limit slot, it pushes the limit The positioning rod 322 is retracted into the inner side of the adjusting block 32, and the limiting of the adjusting block 32 and the adjusting groove is released; a connecting rod 33 is also provided at the wide end of the adjusting block 32, and elastic members 34 are respectively slidably connected to the two ends of the connecting rod 33, and the two elastic members 34 are respectively slidably matched with the two moving members 3. When the connecting rod 33 approaches the moving member 3, the two elastic members 34 are squeezed to store force. The elastic member 34 includes a rod body and a spring sleeved on the rod body. One end of the rod body is slidably matched with the connecting rod 33 along the length direction of the connecting rod 33, and the other end of the rod body is slidably matched with the moving member 3 along its own length direction. The spring is located between the connecting rod 33 and the moving member 3. When the distance between the connecting rod 33 and the moving member 3 is reduced, the spring is squeezed and the spring is stored.

[0042] When the locking cam 32 is in the locked state, the locking cam 322 is in the locked state, and the locking cam 322 is in the locked state, so that the locking cam 322 is locked.

[0043] When fixing the wire reel 4, the operator only needs to hold the wire reel 4 and place it at a position opposite to the two clamping assemblies and touch the push rod 321. The operation is simple and convenient. Moreover, each clamping member 24 extends into the wire reel 4 and abuts against the inner wall of the wire reel 4 to fix the wire reel 4. Compared with the method of squeezing the wire reel 4 at both ends of the wire reel 4 adopted in the related art, the wire reel 4 is prevented from being squeezed in the axial direction, and the deformation of the wire reel 4 in the axial direction is effectively reduced. At the same time, the clamping assembly improves the fixing strength of the wire reel 4, reduces the loosening of the wire reel 4 during the winding operation, and ensures the winding quality.

[0044] like Figure 2 As shown, in order to facilitate automatic unloading of the bobbin 4 after the bobbin 4 is wound, a reset block 13 is further provided on the frame 1. The reset block 13 is arc-shaped on the side opposite to the bobbin 4. The arc-shaped side of the reset block 13 is inclined from top to bottom in the direction close to the bobbin 4. When the driving member drives the connecting member 2 to rotate in the direction close to the reset block 13, the connecting rod 33 contacts the reset block 13 and squeezes the adjusting block 32 to move in the direction close to the bobbin 4. After the bobbin 4 is wound, the driving member drives the fixing mechanism to rotate until the connecting rod 33 abuts against the reset block 13, and the connecting rod 33 is relative to the reset block 13. When the reset block 13 slides, the reset block 13 squeezes the connecting rod 33 and moves the adjusting block 32 toward the direction close to the bobbin 4. During this process, the adjusting block 32 squeezes the two moving parts 3 to separate, and the moving part 22 is rotatably connected to the moving part 3. When the two moving parts 3 move away from each other, the moving part 22 is driven away from the guide part 23, so that the clamping part 24 is detached from the inside of the bobbin 4, and the bobbin 4 falls onto the frame 1 and is further collected. The connecting rod 33 continues to slide in contact with the reset block 13 until the limit rod 322 limits the adjusting block 32 again, and the fixing mechanism returns to its initial state.

[0045] To facilitate the fixation of the conical wire reel 4, the lengths of the clamping members 24 of the same group of clamping assemblies can be set to be consistent, and the clamping members 24 of the two groups of clamping assemblies can be set to different lengths. The longer clamping member 24 corresponds to the large end of the conical wire reel 4, and the inner end of each clamping member 24 is rotatably provided with a guide wheel, which slides against the inner wall of the wire reel 4.

[0046] The adjustable automatic winding machine provided by the present invention is convenient for fixing and disassembling the wire bobbin, improves the fixing strength of the wire bobbin, reduces the loosening of the wire bobbin during the winding process, and avoids the wire bobbin from being squeezed and deformed during the fixing operation, thereby improving the winding quality and forming quality of the wire material.
