Waxing device and yarn rewinding machine

Abstract

The present invention discloses a waxing device and a yarn rewinding machine, which belong to the field of yarn equipment and are intended to solve the problem that the consumption of the upper wax block and the lower wax block causes the spring to gradually rebound from the compressed state, resulting in a decrease in the waxing effect. The key points of its technical solution are: it includes a connecting column, an upper abutment disk, a lower abutment disk and a lifting assembly. The present invention utilizes a pre-compressed spring to transmit the elastic force to the upper abutment disk through the connecting column, ensuring that the contact pressure of 10N-15N is maintained between the upper wax block and the yarn. When the yarn consumption causes the thickness of the upper wax block and the lower wax block to decrease, the spring pushes the upper abutment disk downward, and synchronously passes through the 30° inclined surface. The pressure transmission component drives the displacement conversion component to move horizontally, so that the displacement conversion component pushes the lower abutment disk upward, forming a dynamic compensation mechanism.

Description

Technical Field

[0001] The present invention relates to the field of yarn equipment, and more particularly to a waxing device and a yarn rewinding machine. Background Art

[0002] The yarn used in textiles needs to undergo a yarn rewinding operation before it is used for weaving. On the one hand, the oversized yarn bobbin is converted to a yarn bobbin suitable for weaving. On the other hand, during the yarn rewinding operation, a layer of wax is applied to the surface of the yarn by rubbing the wax block against the surface of the yarn. This makes the thread smoother during weaving, convenient for processing, and will not break.

[0003] The waxing device of the existing yarn rewinding machine generally includes an upper wax block and a lower wax block. The yarn passes between the upper wax block and the lower wax block to achieve the waxing effect on the yarn, and a spring is provided on one side of the upper wax block to push the upper wax block toward the lower wax block through the spring, thereby ensuring the pressure exerted by the upper and lower wax blocks on the yarn and ensuring the waxing effect.

[0004] However, there is a problem with the above method, that is, due to the consumption of the upper and lower wax blocks, the spring gradually rebounds from the compressed state, resulting in the pressure exerted by the upper and lower wax blocks on the yarn gradually decreasing, resulting in a decrease in the waxing effect and affecting product quality.

[0005] Therefore, new solutions need to be proposed to solve this problem. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a waxing device and a yarn rewinding machine in order to solve the above problems.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: a waxing device comprising:

[0008] The connecting column is fixed on the frame of the yarn rewinding machine through a nut;

[0009] An upper abutting plate, used for abutting against the upper wax block, is slidably arranged on the connecting column, and a spring is further abutted between the upper abutting plate and the connecting column;

[0010] A lower abutment plate, used for abutting against the lower wax block, and slidably arranged on the connecting column;

[0011] A lifting assembly is used to push the lower abutment plate to move toward the upper abutment plate, and a pressure transmission member is provided between the lifting assembly and the upper abutment plate;

[0012] When the upper abutment plate moves toward the direction approaching the lower abutment plate, the upper abutment plate provides driving force to the lifting assembly through the pressure transmission member, so that the lower abutment plate moves toward the direction approaching the upper abutment plate.

[0013] The present invention is further configured as follows: the lifting assembly includes a displacement conversion part, a sliding part is fixedly provided on the side of the lower abutment plate close to the displacement conversion part, the side wall where the displacement conversion part and the sliding part abut is inclined, and the abutment parts where the displacement conversion part and the pressure transmission part abut each other are both inclined.

[0014] The present invention is further configured as follows: the lifting assembly also includes a shell, the displacement conversion member is slidably arranged on the shell, and an extension portion is fixedly provided on the side of the lower abutment plate close to the shell, and the extension portion is embedded in the interior of the shell and is slidably connected to the inner wall of the shell.

[0015] The present invention is further configured such that: a through channel is provided on the connecting column, and the displacement conversion member can be embedded in the through channel.

[0016] The present invention is further configured as follows: the pressure transmission member is configured as a hollow cylindrical structure, an outer edge is formed at the connection between the pressure transmission member and the upper abutment plate, and the outer edge is fixedly connected to the upper abutment plate by bolts;

[0017] The inner side wall of the pressure transmission component abuts against the displacement conversion component, and the inner side wall is arranged obliquely.

[0018] The present invention is further configured such that: the sliding portion is configured as an annular structure, and the abutting surface between the sliding portion and the displacement conversion member is configured to be inclined.

[0019] The yarn rewinding machine comprises a frame and the waxing device mentioned above. The frame is provided with a through hole for the connecting column to pass through. The frame is provided with a wire hanging ring and a wire feeder on both sides of the waxing device.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, a pre-compressed spring is used to transmit elastic force to the upper abutment disk via a connecting column, ensuring a contact pressure of 10N-15N between the upper wax block and the yarn. When yarn consumption causes the thickness of the upper and lower wax blocks to decrease, the spring pushes the upper abutment disk downward, and simultaneously passes through a 30° inclined plane. The pressure transmission component drives the displacement conversion component to move horizontally, causing the displacement conversion component to push the lower abutment disk upward, forming a dynamic compensation mechanism to ensure the waxing effect. When the accumulated compensation reaches a preset value, the displacement conversion component triggers the rotating component, releasing the limit on the warning component, and the warning component pops up, prompting the operator to replace the upper and lower wax blocks.

[0022] Secondly, the present invention combines the waxing device with the existing wire clamping conductor frame, thereby giving the existing wire clamping conductor frame a good waxing effect, reducing the cost of equipment use, and simplifying the complexity of the overall structure.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0034] Waxing device, such as Figure 2-Figure 9 As shown, it includes a connecting column 1, an upper abutting plate 2 for abutting the upper wax block, and a lower abutting plate 3 for abutting the lower wax block, wherein the upper wax block and the lower wax block are placed between the upper abutting plate 2 and the lower abutting plate 3, and the upper abutting plate 2 is slidingly set on the connecting column 1, and a spring 4 is also abutted between the upper abutting plate 2 and the connecting column 1, and after the upper wax block and the lower wax block are placed, the spring 4 is in a compressed state, so that the elastic thrust formed by the spring 4 makes the upper abutting plate 2 form a good pressure effect on the upper wax block, thereby ensuring the waxing effect.

[0035] At the same time Figure 4-Figure 5 As shown, a blocking plate is provided at the place where the connecting column 1 abuts the spring 4, wherein a through hole is provided on the blocking plate, and an internal thread is provided on the inner wall of the through hole. An external thread is provided at one end of the connecting column 1 embedded in the through hole. The position of the blocking plate can be fixed and disassembled by connecting the external thread and the internal thread.

[0036] The detachable blocking plate design makes it convenient for the user to remove the blocking plate, take out the spring 4 and the upper abutment plate 2, and then replenish the upper wax block and the lower wax block.

[0037] like Figure 4-Figure 6 As shown, the waxing device also includes a lifting assembly 5, and the lower abutment disk 3 is slidably set on the connecting column 1, thereby providing implementation conditions for the lifting assembly 5 to push the lower abutment disk 3 to move toward the upper abutment disk 2. At the same time, a pressure transmission component 6 is provided between the lifting assembly 5 and the upper abutment disk 2, so that when the upper abutment disk 2 slides downward, the pressure transmission component 6 provides power to the lifting assembly 5, and then the lower abutment disk 3 can be pushed to move toward the upper abutment disk 2, thereby achieving the upper and lower clamping effect of the upper abutment disk 2 and the lower abutment disk 3, thereby offsetting the problem that the pressure on the yarn gradually decreases due to the gradual rebound of the spring 4 from the compressed state, thereby ensuring the waxing effect.

[0038] Among them Figure 4-Figure 5 As shown, an outer edge 11 is formed at the connection between the pressure transmission member 6 and the upper abutment plate 2. The outer edge 11 is fixedly connected to the upper abutment plate 2 by bolts not shown, so that when the upper abutment plate 2 moves downward, the pressure transmission member 6 will move accordingly, and the upper abutment plate 2 is provided with a sedimentation groove at the position of the outer edge 11, and the flatness of the surface of the upper abutment plate 2 is ensured by the sedimentation groove.

[0039] And as Figure 4-Figure 6As shown, the lifting assembly 5 includes a displacement conversion member 7 for pushing the lower abutment disk 3 to move and a shell 9 fixedly set on the connecting column 1. The displacement conversion member 7 abuts against the pressure transmission member 6, and the abutment parts are inclined. The pressure transmission member 6 and the displacement conversion member 7 adopt a double 30° bevel combination (the contact surface angle is 60°). When the upper abutment disk 2 moves downward, the pressure transmission member 6 converts the vertical movement into the horizontal displacement of the displacement conversion member 7 through the bevel, thereby realizing displacement amplification. At the same time, according to the different efficiency of wax blocks digested by different yarns, the pressure transmission member 6 and the displacement conversion member 7 with bevel designs of different angles can be replaced, so as to better adapt to the needs of the product.

[0040] Thus, Figure 4-Figure 6 As shown, when the pressure transmission member 6 slides downward, the displacement conversion member 7 is pushed to move along with it by the side walls arranged at an angle to each other. At the same time, the displacement conversion member 7 is slidably arranged on the shell 9, and a sliding groove corresponding to the sliding of the displacement conversion member 7 is opened on the shell 9, so that the sliding direction of the displacement conversion member 7 is guided by the sliding groove to ensure the stability of the transmission effect.

[0041] At the same time Figure 4 、 Figure 5 、 Figure 6 and Figure 9 As shown, an extension portion is fixedly provided on one side of the lower abutment disk 3 close to the shell 9, and the extension portion is embedded in the shell 9 and is slidably connected to the inner wall of the shell 9. The lower abutment disk 3 is now embedded in the extension portion to guide the upward sliding direction, thereby avoiding the position of the lower abutment disk 3 from being offset, affecting the clamping and waxing effect of the upper and lower wax blocks on the yarn, and the extension portion is used to block the gap formed between the lower abutment disk 3 and the shell 9 after it moves upward, thereby preventing external impurities from entering the interior of the shell 9.

[0042] And as Figure 4 、 Figure 5 and Figure 9 As shown, the housing 9 has an inner edge formed on the side close to the lower abutment plate 3, and the extension portion has an outer edge formed on the end away from the lower abutment plate 3. The cooperation between the inner and outer edges prevents the lower abutment plate 3 from falling off the housing 9. The extension portion has a certain elastic deformation capacity, thereby ensuring that the extension portion can be smoothly embedded in the housing 9 when the housing 9 and the lower abutment plate 3 are installed. In addition, the edge lines of the outer and inner edges are both rounded to reduce bumps and jams during the embedding process.

[0043] At the same time Figure 4 、 Figure 5 、 Figure 6 and Figure 9As shown, a sliding portion 8 is fixedly provided on one side of the lower abutment plate 3 close to the displacement conversion member 7, and the side wall where the displacement conversion member 7 and the sliding portion 8 abut is inclined, so that when the displacement conversion member 7 slides, the sliding portion 8 is synchronously driven to move accordingly, thereby driving the position of the lower abutment plate 3 to form a lifting effect.

[0044] Among them Figure 7 As shown, the pressure transmission component 6 is configured as a hollow cylindrical structure and is sleeved on the outside of the connecting column 1, thereby ensuring the sliding direction and stability of the pressure transmission component 6, and further ensuring the stability of the pressure transmission component 6 in providing power to the lifting component 5.

[0045] At the same time Figure 6 As shown, there are two displacement conversion members 7, and they are symmetrically arranged around the connecting column 1, so that the pressure transmission member 6 and the plurality of displacement conversion members 7 are in synchronous contact, ensuring uniform force between the pressure transmission member 6 and the displacement conversion member 7, and ensuring that when the lower abutment plate 3 is lifted, the lower abutment plate 3 can be stably stressed and form displacement.

[0046] At the same time Figure 5 As shown, the inner side wall of the pressure transmission member 6 is in contact with the displacement conversion member 7, and the inner side wall is inclined, so that the downward movement of the pressure transmission member 6 will push several displacement conversion members 7 to move closer to the connecting column 1, and a through channel 10 is provided on the connecting column 1, and the displacement conversion member 7 can be embedded in the through channel 10, thereby increasing the displacement space during the movement of the displacement conversion member 7 closer to the connecting column 1, making the overall structure more compact.

[0047] And as Figure 4 、 Figure 5 As shown, one end of the pressure transmission member 6 passes through the lower abutment plate 3 and is embedded in the shell 9, so that the transmission of the pressure transmission member 6 and the displacement conversion member 7 is hidden inside the structure, thereby effectively reducing external interference.

[0048] And as Figure 9 As shown, the sliding portion 8 is configured as an annular structure. Through the annular structure, when installing the lower abutment plate 3, there is no need to align the connection position between the sliding portion 8 and the displacement conversion member 7, which reduces the difficulty in use and enables it to stably abut against the displacement conversion member 7. In addition, the abutment surface between the sliding portion 8 and the displacement conversion member 7 is inclined, so that by cooperating with the inclined side wall of the displacement conversion member 7, the corresponding lifting height of the lower abutment plate 3 when the displacement conversion member 7 moves is controlled.

[0049] At the same time Figure 4 and Figure 6As shown, the lifting assembly 5 also includes a rotating member 16 rotatably arranged on the shell 9, a warning member 12 and a limiting member 14 slidably arranged on the shell 9, wherein one end of the warning member 12 can extend to the outside of the shell 9, and an elastic element 13 is provided between the warning member 12 and the shell 9 to push the warning member 12 to move toward the outside of the shell 9, and one end of the limiting member 14 is in contact with the warning member 12, and the other end is in contact with the shell 9 to form an elastic element 2 15, and the elastic thrust of the elastic element 2 15 is used to achieve the effect of the limiting member 14 abutting and limiting the displacement of the warning member 12.

[0050] At the same time Figure 6 As shown, the rotating member 16 is used for the transmission connection between the displacement conversion member 7 and the limit member 14, and during the normal use of the equipment, there is a gap between the rotating member 16 and the displacement conversion member 7, so that during the normal consumption of the upper wax block and the lower wax block, the position of the displacement conversion member 7 will move, but at this time the rotating member 16 and the displacement conversion member 7 will not dock, so that the position of the limit member 14 remains fixed. When the upper wax block and the lower wax block are consumed to a preset value, the displacement conversion member 7 abuts against the rotating member 16 and pushes the rotating member 16 to rotate, so that the rotating member 16 pushes the limit member 14 to move away from the warning member 12, so as to release the abutment against the warning member 12, thereby pushing the warning member 12 outward through the elastic element 13, so that the operator can observe the current situation and replace the upper wax block and the lower wax block in time.

[0051] Among them Figure 6 As shown, a groove is provided on the side wall where the warning member 12 abuts the limiting member 14, and the groove enhances the fixing effect formed after the limiting member 14 abuts. At the same time, there are two limiting members 14, and they are symmetrically arranged on both sides of the warning member 12. At the same time, the abutting end of the limiting member 14 is arranged in an arc structure, and the end of the warning member 12 away from the outside of the shell 9 is arranged in a pointed structure. The pointed structure makes it convenient for the user to push the warning member 12 to reset its position later. The warning member 12 is embedded between the two limiting members 14 and pushes the two limiting members 14 to move away from each other.

[0052] At the same time, a through groove is opened on the warning piece 12, and a limit block embedded in the through groove is fixedly provided on the shell 9. The limit block limits the outward movement distance of the warning piece 12 to prevent the warning piece 12 from falling off, and the elastic element 13 is also placed in the through groove. One end of the elastic element 13 abuts against the inner wall of the through groove, and the other end abuts against the limit block, thereby ensuring the effect of pushing the warning piece 12 to move outward and making the overall structure more compact.

[0053] The outer wall of the warning piece 12 is also coated with a paint coating, wherein the paint coating is located at the portion of the warning piece 12 extending to the outside of the shell 9. The paint coating portion improves recognition and reduces omissions during user inspection.

[0054] like Figure 1 As shown, the yarn rewinding machine includes a frame and the above-mentioned waxing device. A through hole is opened on the frame for the connecting column 1 to pass through, so that the connecting column 1 passes through the through hole, and after the shell 9 abuts against the upper surface of the frame, the position of the connecting column 1 is fixed by a nut.

[0055] Working principle: Start the yarn rewinding machine to rewind the yarn, and as the yarn passes through, the upper wax block and the lower wax block are consumed, causing the spring 4 to push the upper abutment disk 2 to move downward, and then the upper wax block fills the gap formed due to consumption to ensure that the upper wax block and the lower wax block are still in contact with the outer surface of the yarn, and when the upper abutment disk 2 moves downward, the pressure transmission member 6 abuts against the displacement conversion member 7, and drives the displacement conversion member 7 to slide accordingly. The displacement conversion member 7 pushes the sliding part 8 to move upward through the inclined side wall, and then the lower abutment disk 3 moves toward the direction close to the upper abutment disk 2, thereby cooperating with the upper abutment disk 2 to form a clamping and squeezing effect on the upper wax block and the lower wax block, increasing the squeezing and clamping effect on the yarn between the upper wax block and the lower wax block, ensuring that the upper wax block and the lower wax block form good pressure on the yarn, and ensuring the waxing effect.

[0056] As the upper wax block and the lower wax block are consumed, the sliding distance of the displacement conversion member 7 also increases, and then the displacement conversion member 7 abuts against the rotating member 16 and pushes the rotating member 16 to rotate, so that the rotating member 16 pushes the limiting member 14 to move away from the warning member 12, so as to release the abutment against the warning member 12, and thereby pushes the warning member 12 outward through the elastic element 13, so that the operator can observe the current situation and replace the upper wax block and the lower wax block in time.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0058] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
