Description

Technical Field

[0001] The embodiments of this utility model relate to the field of wire processing machinery technology, specifically, to a multi-station wire processing armoring machine. Background Technology

[0002] In wire manufacturing, the armoring process is a crucial step in enhancing wire strength and durability. The armoring machine's stranding mechanism tightly wraps steel wire around the outer wall of the copper layer inside the wire, significantly improving its tensile and abrasion resistance without affecting signal or power transmission. This process is widely used in power transmission, communication engineering, and other fields. The roller assembly at the output end of the armoring machine plays a key role as the final guiding structure for wire output. Firstly, the symmetrically arranged rollers flexibly hold the armored wire, preventing it from shifting due to gravity or transmission inertia, and preventing scratches caused by friction between the wire surface and the output edge. Secondly, the rollers' rotational characteristics reduce output resistance, ensuring continuous feeding efficiency during multi-station processing. The existing roller connection structure of the multi-station wire-mounting armoring machine, taking the Chinese utility model patent "A Multi-station Wire-mounting Armoring Machine" with publication number CN216250188U as an example, in its disclosed technical solution, the roller is mounted on a fixed base by a rotatable connection, and the fixed base is fixedly connected to a connecting rod. The connecting rod is slidably set in the mounting groove of the transmission cabinet, and its vertical position is adjusted by means of a first lifting rod and a second lifting rod in the mounting groove to adapt to the clamping requirements of wires of different diameters. Although this structure can meet the basic guiding and clamping functions, it has significant defects in the roller maintenance and replacement process: Because the outer layer of the roller needs to be made of rubber to achieve flexible clamping and avoid damage to the surface of the wire, the rubber material is prone to wear, aging or surface cracking under long-term friction with the wire and the action of dust and impurities in the processing environment. It needs to be replaced regularly to ensure clamping stability. However, the roller connection structure used in patent CN216250188U does not have a targeted quick-release mechanism. The roller and the fixed seat, and the fixed seat and the connecting rod are all rigidly fixed connections. When the rubber roller is worn, the operator needs to replace it according to the following steps: First, the limiting structure of the first lifting rod and the second lifting rod on the connecting rod needs to be removed, and the connecting rod needs to be pulled out of the mounting groove as a whole; then, the fastening parts between the fixed seat and the connecting rod need to be removed to separate the fixed seat from the connecting rod; finally, the worn roller can be removed from the fixed seat by removing the bearing end cover or shaft retaining ring of the roller. The aforementioned roller replacement process involves the disassembly and assembly of at least three to four related components, requiring the use of various tools such as wrenches, screwdrivers, and pins. Each replacement takes a long time. Since armoring machines are mostly continuous production equipment, the replacement of rollers at a single station requires machine shutdown. Especially for multi-station equipment, even maintenance at just one station may force the entire machine or adjacent stations to stop, affecting production efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a multi-station armoring machine for wire processing, which solves the technical problem that the existing technology requires tools to change rollers, and the time spent on each change is long, which affects production efficiency.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0017] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0021] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] like Figure 1 and Figure 4 As shown, it illustrates a multi-station wire processing armoring machine according to an embodiment of the present invention, including a base 1, a transmission cabinet 101, a protective cover 102, and rollers 103. The transmission cabinet 101 has multiple grooves 2 on one side. The inner cavity of each groove 2 is slidably connected to a connecting ear plate 201 via a guide rod. The inner cavity of the connecting ear plate 201 is detachably connected to a fixing pin 202 via a locking assembly. The locking assembly includes a support plate 3 fixedly connected to one side of the connecting ear plate 201. A snap-fit ​​post 301 is slidably connected to the inner cavity of the support plate 3. A pressing block 302 is fixedly connected to one end of the snap-fit ​​post 301. An elastic element a303 is provided between the snap-fit ​​post 301 and the connecting ear plate 201. A snap-fit ​​hole 304 adapted to the snap-fit ​​post 301 is opened on the surface of the fixing pin 202. An installation sleeve 305 is fixedly connected to the top of the connecting ear plate 201 outside the pressing block 302. The inner cavity of the mounting sleeve 305 is provided with a limiting structure for restricting the position of the snap-fit ​​post 301. In some examples, the roller 103 to be installed can be placed into the inner cavity of the connecting ear plate 201. The inner cavity of the connecting ear plate 201 is reserved with space to accommodate the roller 103 so that the roller 103 can rotate flexibly. At the same time, it is ensured that the center hole of the roller 103 is coaxial with the through holes on both sides of the connecting ear plate 201 to prepare for the insertion of the fixing pin 202. This process matches the detachable connection relationship between the connecting ear plate 201 and the fixing pin 202.

[0023] For example, such as Figure 3 As shown, the overall supporting function of the base 1, the assembly reference function of the transmission cabinet 101, and the relative assembly positions of the connecting ear plate 201 and the roller 103 can be clearly demonstrated, intuitively reflecting the connection logic of the core components in the document 1.

[0024] like Figure 3 As shown, the limiting structure includes two flip plates 4 rotatably connected to the inner cavity of the mounting sleeve 305 via pins. The two flip plates 4 are symmetrically designed. Each flip plate 4 has an elastic element b401 fitted on the pin surface. Each flip plate 4 has a limiting block 402 fixedly connected to one end facing the pressing block 302. Both ends of the pressing block 302 have multiple limiting grooves 403 that are adapted to the limiting block 402.

[0025] In some examples, when the pressing block 302 is pressed, the locking post 301 can slide along the inner cavity of the support plate 3. After the locking post 301 passes through the side wall of the connecting ear plate 201, it moves closer to the locking hole 304. At the same time, the pressing block 302 moves down and squeezes the limiting block 402 of the flip plate 4, causing the two symmetrical flip plates 4 to rotate around the pin shaft and the elastic element b401 to generate a torsional force. This process corresponds to the limiting structure's function of limiting the position of the locking post 301.

[0026] For example, such as Figure 4 As shown, the symmetrical distribution of the inner cavity flip plate 4 of the mounting sleeve 305, the cooperation relationship between the elastic element b401 and the pin shaft, and the relative positions of the limiting block 402 and the pressing block 302 can be clearly presented.

[0027] like Figure 4 As shown, both the limiting groove 403 and the limiting block 402 are triangular structures, and the elastic element b401 is a torsion spring.

[0028] In some examples, when the snap-fit ​​post 301 is fully engaged in the snap-fit ​​hole 304 of the fixing pin 202, the elastic element b401 releases the torsional force to drive the flip plate 4 to reset, and the triangular limiting block 402 will be precisely engaged in the triangular limiting groove 403, thereby achieving position locking of the snap-fit ​​post 301 through structural adaptation.

[0029] For example, such as Figure 4 As shown, the triangular outlines of the limiting groove 403 and the limiting block 402, as well as the installation status of the elastic element b401 (torsion spring), can be clearly displayed through partial cross-section.

[0030] like Figure 2 As shown, each connecting ear plate 201 has a slidably connected positioning block 5 in its inner cavity. An elastic element c501 is provided between the positioning block 5 and the connecting ear plate 201. The surface of the fixing pin 202 is provided with a positioning hole 502 that matches the positioning block 5.

[0031] In some examples, when the fixing pin 202 is pushed axially through the connecting ear plate 201 and the roller 103, the surface of the fixing pin 202 will press the positioning block 5 in the inner cavity of the connecting ear plate 201. The positioning block 5 slides and contracts along the inner cavity of the connecting ear plate 201, and the elastic element c501 is compressed, so the fixing pin 202 can be continuously pushed forward without rotating it.

[0032] For example, such as Figure 3 As shown, the installation position of the inner cavity positioning block 5 of the connecting ear plate 201, the connection relationship of the elastic element c501, and the correspondence between the fixing pin 202 and the positioning hole 502 can be clearly shown.

[0033] like Figure 3 As shown, both the positioning block 5 and the positioning hole 502 are hemispherical structures, and the outer diameter of the positioning block 5 is adapted to the inner diameter of the positioning hole 502.

[0034] In some examples, after the fixing pin 202 is inserted into place, it rotates. When the positioning hole 502 of the hemispherical structure rotates to the position corresponding to the hemispherical positioning block 5, the positioning block 5 automatically engages with the positioning hole 502 under the reset force of the elastic element c501. The axial positioning of the fixing pin 202 is achieved through the adaptation of the hemispherical structure, and at the same time, the snap-fit ​​hole 304 is coaxially aligned with the snap-fit ​​post 301.

[0035] For example, such as Figure 3 As shown, the hemispherical outlines of the positioning block 5 and the positioning hole 502, as well as their fitting gap, can be clearly displayed.

[0036] like Figure 2 As shown, the surface of the guide rod is fitted with two sets of elastic elements d6. One end of each set of elastic elements d6 is fixedly connected to the inner wall of the groove 2, and the other end abuts against one end of the connecting ear plate 201.

[0037] In some examples, when the armored wire is output from the transmission cabinet 101 to the roller 103, if the wire diameter fluctuates or is subjected to inertial impact, the connecting ear plate 201 will slide along the guide rod in the inner cavity of the groove 2. At this time, the two sets of elastic elements d6 will generate elastic deformation by abutting against the inner wall of the groove 2 and the end of the connecting ear plate 201, respectively, to buffer the sliding impact force of the connecting ear plate 201. This process corresponds to the buffering function of the guide rod and the elastic element d6.

[0038] For example, such as Figure 2 As shown, the distribution of the two sets of elastic elements d6 on the surface of the guide rod, as well as the connection relationship between the elastic elements d6 and the groove 2 and the connecting ear plate 201, can be clearly displayed.

[0039] like Figure 3As shown, the roller 103 is sleeved on the surface of the fixing pin 202 through the bearing. The surface of the roller 103 is provided with an annular groove 7 adapted to the wire. The surface of the annular groove 7 is provided with anti-slip texture, which is a diamond-shaped anti-slip texture.

[0040] In some examples, the roller 103 rotates flexibly through the cooperation of the bearing and the fixing pin 202. When the wire is conveyed, it is embedded in the annular groove 7 on the surface of the roller 103. The annular groove 7 radially limits the wire, while the diamond-shaped anti-slip pattern increases the friction with the surface of the wire to prevent the wire from slipping.

[0041] For example, such as Figure 3 As shown, the bearing connection structure between the roller 103 and the fixing pin 202, and the outline of the annular groove 7 can be clearly displayed.

[0042] like Figures 1-4 As shown, elastic element a303 is a tension spring, elastic element c501 and elastic element d6 are both compression springs, and the inner cavity of the protective cover 102 is provided with an observation window 8.

[0043] In some examples, when the snap-fit ​​post 301 moves down to snap-fit, it stretches the elastic element a303 (tension spring); when the positioning block 5 retracts, it compresses the elastic element c501 (compression spring); and when the connecting ear plate 201 slides, it compresses the elastic element d6 (compression spring). Each elastic element achieves its function through different deformation methods. At the same time, during the processing, the operator can monitor the wire conveying and roller 103 working status in real time through the observation window 8 inside the protective cover 102.

[0044] For example, such as Figures 1-4 As shown, the assembly position of the observation window 8 inside the protective cover 102 and the role of each elastic component in the overall structure can be clearly displayed.

[0045] Working principle With the base 1 as the whole support, the transmission cabinet 101 provides the assembly reference. First, put the roller 103 to be installed into the inner cavity of the connecting ear plate 201 (the inner cavity of the connecting ear plate 201 is reserved with space to match the roller 103, so that the roller 103 can rotate flexibly). At the same time, ensure that the center hole of the roller 103 is coaxial with the through holes on both sides of the connecting ear plate 201, so as to prepare for the installation of the fixing pin.

[0046] Take the fixing pin 202 and align one end with the through hole on one side of the connecting ear plate 201. Push the fixing pin 202 axially. At this time, the positioning block 5 in the inner cavity of the connecting ear plate 201 remains extended under the elastic force of the elastic element c501. When the surface of the fixing pin 202 contacts the positioning block 5, it will squeeze the positioning block 5 to slide and retract along the inner cavity of the connecting ear plate 201 (the elastic element c501 is compressed). The fixing pin 202 can be continuously pushed forward without rotating it. Until the fixing pin 202 completely passes through the through hole on one side of the connecting ear plate 201, the center hole of the roller 103, and the through hole on the other side of the connecting ear plate 201, the "through-hole" state is achieved. After the pin is inserted into place, rotate the fixing pin 202: when the positioning hole 502 on the surface of the fixing pin 202 rotates to the position corresponding to the positioning block 5, the positioning block 5 automatically engages into the inner cavity of the positioning hole 502 under the reset elastic force of the elastic element c501, thereby achieving axial positioning of the fixing pin 202; at the same time, as the fixing pin 202 rotates, the snap-fit ​​hole 304 on its surface rotates synchronously to be coaxially aligned with the snap-fit ​​post 301 in the inner cavity of the support plate 3 on one side of the connecting ear plate 201, thus completing the pre-positioning; Pressing the pressing block 302 causes the locking pin 301 to slide along the inner cavity of the support plate 3. After the locking pin 301 passes through the side wall of the connecting ear plate 201, it is precisely locked into the locking hole 304 of the fixing pin 202 (during this process, the elastic element a303 is stretched). At the same time, when the pressing block 302 moves down, it squeezes the limiting block 402 of the flip plate 4 in the inner cavity of the mounting sleeve 305, causing the two symmetrical flip plates 4 to rotate around the pin shaft (the elastic element b401 is subjected to torsional force). When the locking pin 301 is fully locked into the locking hole 304, the elastic element b401 releases the torsional force and drives the flip plate 4 to reset. The limiting block 402 is locked into the limiting groove 403 of the pressing block 302, locking the position of the locking pin 301, and finally achieving a stable fixation between the roller 103 and the connecting ear plate 201. After the armored wire is processed, it is output from the inside of the transmission cabinet 101 and enters the roller 103 area. The roller 103 has an annular groove 7 that is adapted to the wire, which can radially limit the wire and prevent it from deviating during the conveying process. The diamond-shaped anti-slip texture on the surface of the annular groove 7 can increase the friction with the surface of the wire, prevent the wire from slipping, and ensure that the conveying speed matches the processing rhythm. If there are slight fluctuations in the diameter of the wire or if it is impacted by the inertia of the conveying process, the connecting ear plate 201 will slide along the guide rod inside the groove 2 to adjust its position. The two sets of elastic elements d6 sleeved on the surface of the guide rod abut against the inner wall of the groove 2 and the end of the connecting ear plate 201, respectively. The elastic deformation can buffer the sliding impact force of the connecting ear plate 201, so that the roller 103 always fits against the surface of the wire, maintains a stable clamping force, and avoids damage to the surface of the wire due to excessive or insufficient clamping.

[0047] During the processing, the operator can directly observe the internal wire processing process through the observation window 8 embedded in the inner cavity of the protective cover 102. Abnormalities can be detected in time without disassembling the protective cover 102, ensuring the continuity of processing. When roller 103 needs to be replaced due to wear of the rubber layer caused by long-term friction, follow these steps: Manually press the two flip plates 4 inside the mounting sleeve 305 to make the flip plates 4 rotate around the pin shaft. The limiting block 402 at its end disengages from the limiting groove 403 of the pressing block 302, releasing the position restriction on the pressing block 302. At this time, the locking pin 301 slides automatically upward along the inner cavity of the support plate 3 under the pulling force of the elastic element a303, completely disengaging from the locking hole 304 of the fixing pin 202, releasing the radial lock of the fixing pin 202. Rotate the fixing pin 202 to make the positioning hole 502 on the surface of the fixing pin 202 misalign with the positioning block 5; the surface of the fixing pin 202 presses against the positioning block 5, and the positioning block 5 slides and contracts along the inner cavity of the connecting ear plate 201 (the elastic element c501 is compressed), completely disengaging from the positioning hole 502, thus releasing the axial positioning of the fixing pin 202. Pull the fixing pin 202 outward so that it passes through the through hole on the other side of the connecting ear plate 201, the center hole of the roller 103 and the through hole on one side of the connecting ear plate 201 in sequence, and completely detaches from the connecting ear plate 201; finally, remove the worn roller 103 from the inner cavity of the connecting ear plate 201 to complete the disassembly. Then, install the new roller 103 according to the installation steps to resume processing. In the overall wire armoring process of this multi-station wire processing armoring machine, the core processing principle involving the winding of steel wire onto the surface of the wire (including key technical aspects such as the power transmission path of the stranding mechanism, the tension control method of steel wire release, and the adaptation and adjustment mechanism of steel wire winding pitch) has been fully and detailedly disclosed in the prior art document "A Multi-station Wire Processing Armoring Machine" with publication number CN216250188U. The innovative improvements of this utility model focus on optimizing the detachable connection structure between the discharge end roller and the connecting ear plate, improving the efficiency of roller disassembly and maintenance, and the clamping stability during wire conveying. It does not improve the basic processing principle of the winding of steel wire onto the surface of the wire. Therefore, the specific working principle of the winding of steel wire onto the surface of the wire will not be repeated in this utility model. The relevant technical details can be directly referred to the corresponding technical content of the above-mentioned prior art document.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
