Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of carat tube production molds, and in particular, to a mold mounting table for carat tube processing. Background Art

[0002] In the production of carat tubes, the mold mounting table is a critical component used to shape and determine the structure and size of the tube. Its structure affects product processing efficiency and quality. The typical steps in carat tube processing include winding, cutting, demolding, trimming, and pre-embedding of thermal fuses. During winding, the molten flat material strip and circular reinforcing ribs are wound around the heated mold in tandem and simultaneously. During cutting, the pipe socket and insert are cut to size. During demolding, the mold is deformed to reduce the outer contour to allow the tube to release from the mold. After trimming to a smooth and standardized appearance, a thermal fuse is pre-embedded in the socket, completing the product. After winding, the molding is typically cooled and molded with water spray; otherwise, subsequent demolding is impossible. However, pre-embedding the thermal fuse after cooling can be difficult to install because the carat tube has already been cooled and formed. Therefore, the existing technology suffers from low efficiency and inconvenience in pre-embedding the thermal fuse. Summary of the Invention

[0003] To overcome the above-mentioned defects, the embodiments of the present disclosure provide a mold installation table for carat tube processing, which solves the technical problems of low efficiency and inconvenience in pre-buried installation of electric thermal fuses during carat tube processing in the prior art.

[0004] According to one aspect, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, comprising:

[0005] Support rollers, wherein two support rollers form a group and are arranged in two groups;

[0006] A mold roller, both ends of which are placed in contact with the support roller and can be driven to rotate by the support roller to form a carat tube. One end of the mold roller has a first annular groove for accommodating an electric thermal fuse.

[0007] For example, in at least one embodiment of the present disclosure, a mold mounting table for processing carat tubes is provided, wherein the depth of the first annular groove is one-half to one-third of the width of the thermal fuse.

[0008] For example, at least one embodiment of the present disclosure provides a mold mounting station for carat tube processing, wherein the mold roller is hollow inside and has a straightening guide channel on the roller wall. The straightening guide channel is arc-shaped and communicates with the first annular groove at one end and with the mold roller at the other end, further comprising:

[0009] A feeding shaft is used to feed the electric thermal fuse, and is configured so that the fed electric thermal fuse first passes through the straightening guide channel and then circles around the first annular groove.

[0010] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, wherein one side of the first annular groove has a first annular accommodating space communicating with the first annular groove, and further includes:

[0011] An annular clamping member is slidably arranged in the first annular accommodating space and is configured to slide to the first annular accommodating space or to the first annular groove after sliding, and can clamp the electric thermal fuse when sliding to the first annular groove.

[0012] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, wherein the electric thermal fuse is wavy and has a plurality of wavy grooves arranged in sequence, and the annular clamp has a plurality of circumferentially arranged protrusions, which are used to be clamped in the wavy grooves.

[0013] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, wherein the annular clamp has an operating portion that penetrates the inner wall of the mold roller and extends into the hollow interior of the mold roller, and further includes:

[0014] A first elastic member, wherein one end of the first elastic member acts on the annular clamping member and the other end acts on the mold roller, providing a force for the annular clamping member to slide closer and for the protrusion to slide into the first annular groove.

[0015] For example, in at least one embodiment of the present disclosure, a mold mounting table for carat tube processing is provided, wherein the mold roller further has a second annular groove, the second annular groove being located on a side of the first annular groove away from the first annular accommodating space, and a connecting opening being provided between the second annular groove and the first annular groove, and the second annular groove and the first annular groove being connected through the connecting opening, so that the thermal fuse can be wound around the first annular groove once and then around the second annular groove once.

[0016] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, wherein the second annular groove has a second annular accommodating space on a side away from the first annular groove, and the annular clamp is also slidably disposed in the second annular accommodating space for clamping the electric thermal fuse wound in the second annular groove, and further includes:

[0017] A second elastic member, one end of the second elastic member acts on the annular clamping member in the second annular accommodating space, and the other end acts on the mold roller, providing a force for the annular clamping member in the second annular accommodating space to slide closer and cause the protrusion to slide into the second annular groove.

[0018] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, wherein the mold roller includes:

[0019] a first roller petal and a second roller petal, wherein one end of the first roller petal is hinged to one end of the second roller petal, and a gap is formed between the other end of the first roller petal and the other end of the second roller petal;

[0020] The third roller petal is relatively slidably arranged on the first roller petal, and can block the gap after sliding, so that the first roller petal, the second roller petal and the third roller petal form a cylindrical shape.

[0021] For example, at least one embodiment of the present disclosure provides a mold mounting table for carat tube processing, further comprising:

[0022] A nut, the nut being arranged on the inner wall of the third roller petal;

[0023] a screw rod rotatably disposed on the first roller petal and threadably connected to the nut;

[0024] An operating rod is rotatably arranged on the first roller petal, the length direction of the operating rod is parallel to the axial direction of the mold roller, and the operating rod is transmission-connected to the screw rod through a bevel gear.

[0025] The beneficial effects of the embodiments of the present disclosure are:

[0026] In this disclosure, by pre-setting a first annular groove on the mold roller to accommodate the thermal fuse, the thermal fuse is naturally embedded during the carat tube winding process. This avoids the cumbersome step of installing the thermal fuse after cooling and forming in traditional methods, significantly improving the efficiency of pre-embedding the thermal fuse. This eliminates the need to install the thermal fuse on the carat tube after cooling, reducing installation difficulty, making the entire installation process more convenient and efficient, and reducing operator labor intensity.

DETAILED DESCRIPTION

[0038] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0039] To simplify the drawings, only the parts relevant to the disclosure are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0040] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0041] In the present disclosure, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

Therefore, they should not be understood as limitations on the present disclosure.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] like Figures 1 to 9 , which shows a mold mounting table for carat tube processing in one embodiment of the present disclosure, including support rollers 100, with two support rollers 100 arranged in a group. The two ends of the mold roller 200 are placed in abutment with the support rollers 100 and can be driven to rotate by the support rollers 100 to form the carat tube. One end of the mold roller 200 has a first annular groove 201 for accommodating an electric thermal fuse.

[0045] For example, the support rollers 100 are cylindrical, and the two rollers in each set of support rollers 100 are arranged in parallel, and the spacing between them can be adjusted according to the diameter of the mold roller 200. The two sets of support rollers 100 are arranged in sequence on the mounting table to form a straight line to ensure that the mold roller 200 can be placed stably and driven to rotate.

[0046] Among them, the support roller 100 supports the mold roller 200. In order to realize the rotation of the mold roller 200, a driving roller can be added to abut against the mold roller 200 and drive the mold roller 200 to rotate. Alternatively, a support roller 100 with driving force can be selected and connected to the motor to make it an active roller. The motor is used to drive the mold roller 200, thereby driving the mold roller 200 to rotate thereon, thereby realizing the rotation drive of the mold roller 200.

[0047] In order to improve the support effect and support stability, the number of support drive rollers 100 can be increased, and the position of the support drive roller 100 can be ensured to be able to always abut the end of the mold roller 200. For example, three or four support drive rollers 100 can be set at one end of the mold roller 200 for support.

[0048] The mold roller 200 is also cylindrical, its surface ensuring a close fit between the flat material strip and the circular reinforcement ribs wound around it, resulting in a smooth inner surface for the carat tube. The ends of the mold roller 200, where they contact the support roller 100, have a certain degree of roughness to increase friction, ensuring stable rotation of the mold roller 200 as the support roller 100 rotates.

[0049] The first annular groove 201 is located at one end of the mold roller 200 and is annular in shape. The depth and width are designed according to the specifications of the thermal fuse to ensure that the thermal fuse can be tightly placed in the groove and will not be displaced during subsequent processing.

[0050] Two sets of support rollers 100 support both ends of the mold roller 200, ensuring stability during rotation and preventing it from shaking or tilting. This ensures that the carat tubes wound around the mold rollers 200 have uniform wall thickness and good roundness. The support rollers 100 are driven by a drive motor, and their speed can be flexibly adjusted according to different stages of the production process to meet the varying speed requirements during the carat tube winding process.

[0051] A first annular groove 201 is provided at one end of the mold roller 200. The thermal fuse is placed within this groove before the carat tube is wound and formed. This allows the thermal fuse to be naturally embedded in the tube's socket during subsequent processing as the tube is wound around the mold roller 200. Furthermore, the newly wound tube material is heated, ensuring a more effective and convenient embedding process. This avoids the installation difficulties and inefficiencies associated with traditional methods that embed the thermal fuse after the tube has cooled and formed.

[0052] Before the carat tube winding process, the thermal fuse is placed in the first annular groove 201 at one end of the mold roller 200 according to the specified length and shape to ensure that the thermal fuse is fixed in the groove.

[0053] During winding, the drive motor is activated, causing multiple sets of support rollers 100 to rotate synchronously, thereby driving the mold roller 200. The flat strip and circular reinforcing ribs, heated to a predetermined temperature, are sequentially and synchronously wound around the rotating mold roller 200. During the winding process, the speed of the drive motor is adjusted to control the winding speed according to process requirements, ensuring a close fit between the flat strip and the circular reinforcing ribs, forming a uniform winding layer. Furthermore, the mold roller 200 can be sprayed with water for cooling during the winding process as needed to promote the initial formation of the carat tube.

[0054] After winding is complete, the mold roller 200 continues to rotate, driving the wound carat tube into the cutting process. During this process, the tube's socket and insert ports are cut according to the required dimensions. After cutting, the demolding process begins. By deforming the mold roller 200, for example, by using an internal hydraulic device to reduce its outer profile, the carat tube is released from the mold roller 200. The demolded carat tube undergoes a finishing process to achieve a smooth and standardized appearance. Because the thermal fuse is pre-embedded in the first annular groove 201 of the mold roller 200 before winding, it is naturally embedded in the tube's socket as the carat tube is wound and formed. This eliminates the need for additional installation after cooling and forming, significantly improving the efficiency and convenience of pre-embedding the thermal fuse.

[0055] By pre-arranging the first annular groove 201 on the mold roller 200 to place the thermal fuse, the thermal fuse is naturally pre-buried during the winding process of the carat tube, avoiding the tedious steps of installing the thermal fuse after cooling and forming in the traditional method, and significantly improving the efficiency of pre-buried thermal fuse.

[0056] There is no need to install the electric thermal fuse on the cooled carat tube, which reduces the installation difficulty, makes the entire installation process more convenient and quick, and reduces the labor intensity of the operator.

[0057] Due to the improvement of the pre-buried efficiency of the electric thermal fuse and the smooth progress of the entire processing process, the stagnation time in the production process is reduced, the overall production efficiency of the carat tube is improved, and the production cost is reduced.

[0058] In some examples, the thermal fuse can be long and narrow and bends back and forth into a wavy shape. The depth of the first annular groove 201 is between one-half and one-third the width of the thermal fuse. The depth of the first annular groove 201 is precisely determined based on the actual thermal fuse specifications. Assuming a common thermal fuse width range of 3-6 mm, and based on the requirement of a depth between one-half and one-third the width, for a 6 mm thermal fuse, the depth is designed to be 3 mm. In actual production, the depth value will be fine-tuned within the above range for thermal fuses of different widths, taking into account potential tolerances and installation convenience.

[0059] For example, Figure 2 As shown, after the electric thermal fuse is placed in the first annular groove 201, it can be ensured that it will not easily jump out of the groove during the rotation of the mold roller 200, and will not be difficult to install and remove due to being too deep.

[0060] During the carat tube winding process, as the flat material strip and circular reinforcing ribs are continuously wound around the mold roller 200, the thermal fuse is gradually wrapped around the carat tube's socket. The portion of the thermal fuse located within the first annular groove 201 is not inserted into the winding layer; this portion remains exposed outside the carat tube, preventing the entire thermal fuse from being inserted into the winding layer. The appropriate annular groove depth ensures a good bond between the thermal fuse and the winding material, preventing excessive protrusion of the thermal fuse from affecting the smoothness of the winding layer, nor does excessive depth result in a loose bond with the winding material.

[0061] The depth of the first annular groove 201 is set between half and one-third of the width of the thermal fuse to strike a balance between ensuring stable installation of the thermal fuse and tight integration with the carat tube. The shallower depth facilitates the fusion of the thermal fuse with the winding material during the winding process, ensuring that the thermal fuse is firmly embedded in the carat tube after it is formed. This depth range also facilitates placing the thermal fuse into the groove before processing and cleaning and reinstalling the thermal fuse after processing.

[0062] This depth range is versatile enough to accommodate a variety of thermal fuse widths. Whether using narrow or wide thermal fuses, the annular groove depth can be adjusted within a range of one-half to one-third the width to achieve optimal fit, thereby improving the mold mounting platform's adaptability to varying carat tube production requirements.

[0063] In some examples, the mold roller 200 is hollow inside, and the roller wall has a straightening guide channel 202. The straightening guide channel 202 is arc-shaped and one end is connected to the first annular groove 201, and the other end is connected to the mold roller 200. It also includes a feeding shaft 300. The feeding shaft 300 is used to feed the thermal fuse, and is configured so that the fed thermal fuse first passes through the straightening guide channel 202 and then circles around the first annular groove 201.

[0064] For example, Figure 2 、 Figure 7 As shown, the mold roller 200 is designed with a hollow interior. The centering guide channel 202 on the roller wall is arc-shaped, its curvature matching the outer contour of the mold roller 200. The radius is determined by the size of the mold roller 200. The width of the channel is slightly larger than the diameter of the thermal fuse, ensuring smooth movement of the thermal fuse within the channel without excessive shaking. One end of the centering guide channel 202 connects to the first annular groove 201, and the other end connects to the hollow interior of the mold roller 200. A smooth transition design is used at the connection to prevent obstruction of the thermal fuse during passage.

[0065] The feed shaft 300 is mounted on the inner wall of the mold roller 200 and is mounted via bearings and brackets to ensure that it can rotate flexibly. The feed shaft 300 is wound with an electric fuse coil, and the electric fuse coil can be fed out, for example, by manually pulling the electric fuse coil out by an operator.

[0066] In order to ensure that the thermal fuse can accurately enter the straightening guide channel 202 , a guide rod or a guide wheel can be provided near the feeding shaft 300 to ensure that the thermal fuse can smoothly enter the straightening guide channel 202 .

[0067] The arc-shaped design of the centering guide channel 202 matches the outer contour of the mold roller 200, guiding the thermal fuse wire along the circumference of the mold roller 200. This ensures that the fuse wire has the correct orientation before entering the first annular groove 201, thereby ensuring that the fuse wire wraps evenly around the first annular groove 201. This design avoids potential twisting and tangling of the fuse wire when entering the annular groove, thereby improving the quality of the pre-embedded thermal fuse wire.

[0068] The speed-regulating motor on the feed shaft 300 precisely controls the feed speed of the thermal fuse, matching it to the rotational speed of the mold roller 200. During the carat tube winding process, the speed of the feed shaft 300 is adjusted by the speed-regulating motor based on the rotational speed of the mold roller 200 and the required speed for pre-embedding the thermal fuse, ensuring accurate and uniform pre-embedding of the thermal fuse within the first annular groove 201. The provision of a guide sleeve further ensures that the thermal fuse accurately enters the straightening guide channel 202, preventing the thermal fuse from being unable to enter the channel smoothly or becoming stuck at the channel entrance due to feed direction deviation.

[0069] The coordinated work of the straightening guide channel 202 and the feed shaft 300 ensures that the electric thermal fuse can be accurately and evenly embedded in the first annular groove 201, thereby improving the accuracy of the pre-embedding of the electric thermal fuse and ensuring the quality of the electric thermal fuse at the socket of the carat tube, thereby improving the reliability of the carat tube during connection.

[0070] The pre-embedded electric thermal fuse avoids the problems of twisting, knotting, overlapping and other problems that may occur in the pre-embedded electric thermal fuse, ensuring the consistency and stability of the electric thermal fuse at the socket of each carat tube, thereby improving the quality stability of the entire product batch and reducing product quality problems caused by poor pre-embedded electric thermal fuse.

[0071] In some examples, one side of the first annular groove 201 has a first annular accommodating space 203 connected to the first annular groove 201, and also includes an annular clamp 400, which is slidably arranged in the first annular accommodating space 203 and is configured to slide to the first annular accommodating space 203 or slide to the first annular groove 201 after sliding, and can clamp the electric thermal fuse when sliding to the first annular groove 201.

[0072] For example, Figure 9 As shown, the first annular accommodating space 203 is located on one side of the first annular groove 201 and is directly connected to the first annular groove 201. The first annular accommodating space 203 is also annular in shape, and its inner diameter is the same as that of the first annular groove 201, so as to form a space for the annular clamp 400 to slide.

[0073] The first annular accommodating space 203 and the first annular groove 201 are connected by an annular communication opening. The width of the communication opening is adapted to the width of the annular clamping member 400, allowing the annular clamping member 400 to slide smoothly between the two. The edges of the communication opening are smoothly chamfered to prevent scratches on the annular clamping member 400 during sliding or affecting its smooth sliding.

[0074] The annular clamping member 400 is annular in shape as a whole, and will not cause excessive shaking when sliding between the first annular accommodating space 203 and the first annular groove 201 .

[0075] The thermal fuse is secured by sliding the annular clamp 400 between the first annular accommodating space 203 and the first annular groove 201. After the thermal fuse passes through the feed shaft 300 and the straightening guide channel 202 and enters the first annular groove 201 and circles around it, the annular clamp 400 is slid from the first annular accommodating space 203 to the first annular groove 201. At this point, the teeth on the inner sidewall of the annular clamp 400 come into close contact with the thermal fuse. The friction between the teeth and the thermal fuse, as well as the retaining action of the teeth, securely secure the thermal fuse within the first annular groove 201. This ensures that the thermal fuse will not shift due to factors such as the rotation of the mold roller 200 or external forces during the subsequent winding and processing of the carat tube, thereby ensuring the stability of the pre-embedded thermal fuse.

[0076] The annular clamp 400 is designed to be slidable and disposed within the first annular accommodating space 203. When not in use, the annular clamp 400 can be stored within the first annular accommodating space 203, without affecting the feeding of the thermal fuse or the normal operation of the first annular groove 201. When the thermal fuse needs to be secured, the annular clamp 400 can be easily slid into the first annular groove 201 using the operating handle, making operation simple and convenient. This design ensures reliable thermal fuse securement while improving operational flexibility and convenience, adapting to the needs of different production stages.

[0077] In some examples, the electric thermal fuse is wavy and has a plurality of wavy grooves arranged in sequence. The annular clamp 400 has a plurality of circumferentially arranged protrusions 401 , and the protrusions 401 are used to be clamped in the wavy grooves.

[0078] For example, Figure 4 As shown, the thermal fuse adopts a wavy structure. This design not only increases the contact area with the socket of the carat tube, improving the effect of the thermal fusion connection, but also facilitates the connection with the annular clamp 400. The height difference between the crest and trough of the wavy thermal fuse is designed according to actual needs, ensuring sufficient connection area while preventing excessive height difference from affecting placement in the first annular groove 201.

[0079] A plurality of wave grooves are arranged in sequence on the wave-shaped thermal fuse, which are matched with the protrusion 401 of the annular clamp 400 to ensure that the protrusion 401 can be tightly clamped in the wave grooves, thereby firmly fixing the thermal fuse.

[0080] The protrusions 401 on the annular clamp 400 are evenly arranged along the circumference. The number of protrusions 401 is determined by the circumference of the annular clamp 400 and the spacing of the wave grooves on the thermal fuse. This even arrangement ensures uniform distribution of the fixing force on the thermal fuse, preventing displacement of the thermal fuse due to uneven force in a certain area. The protrusions 401 fit neatly into the wave grooves, forming a tight engagement structure.

[0081] The protrusion 401 of the annular clamp 400 cooperates with the wave groove of the thermal fuse to position the thermal fuse. When the annular clamp 400 slides into the first annular groove 201, the protrusion 401 accurately engages the corresponding wave groove, limiting the circumferential and axial movement of the thermal fuse. This effectively prevents the thermal fuse from shifting during the rotation of the mold roller 200 and during the carat tube processing, ensuring the accuracy of the pre-embedded position of the thermal fuse.

[0082] The wavy thermal fuse increases the number of contact points with the annular clamp 400, making the fixing force more evenly distributed. Multiple protrusions 401 simultaneously act on different locations of the thermal fuse, dispersing external forces generated by the rotation and vibration of the mold roller 200, further enhancing the fixing effect and ensuring that the thermal fuse remains stable even in complex processing environments.

[0083] In some examples, the annular clamp 400 has an operating portion 402, which penetrates the inner wall of the mold roller 200 and extends into the hollow interior of the mold roller 200. It also includes a first elastic member 500, one end of the first elastic member 500 acts on the annular clamp 400, and the other end acts on the mold roller 200, providing force for the annular clamp 400 to slide closer and cause the protrusion 401 to slide into the first annular groove 201.

[0084] For example, Figure 2 、 Figure 5 As shown, the operating portion 402 extends from the outer wall of the annular clamp 400 and is in the shape of an elongated plate. The operating portion 402 penetrates the inner wall of the mold roller 200 and extends into the hollow interior of the mold roller 200. The length of the operating portion 402 is designed to allow an operator to easily operate the annular clamp 400 from outside the mold roller 200. The operator can easily grasp and push the operating portion 402 with their fingers or a tool to control the sliding of the annular clamp 400 between the first annular accommodating space 203 and the first annular groove 201.

[0085] The first elastic member 500 can be a spring bar, which allows the annular clamp 400 to stably clamp the thermal fuse while facilitating the operator's ability to overcome the spring force and perform reverse operation. One end of the first elastic member 500 presses against the side of the annular clamp 400 near the operating portion 402, while the other end presses against the inner wall of the first annular accommodating space 203 of the mold roller 200 corresponding to the annular clamp 400, locking the end of the spring bar in place and ensuring that the spring bar does not shift during operation.

[0086] The first elastic member 500 is always in a compressed state, providing a continuous elastic force to the annular clamp 400, causing the annular clamp 400 to slide closer to the first annular groove 201. This allows the protrusion 401 to stably slide into the first annular groove 201 and clamp the thermal fuse. To slide the annular clamp 400 from the first annular groove 201 back into the first annular accommodation space 203, the operator must overcome the elastic force of the first elastic member 500 and pull the annular clamp 400 through the operating portion 402 to achieve reverse sliding of the annular clamp 400.

[0087] The provision of the first elastic member 500 enables the annular clamp 400 to automatically slide toward the first annular groove 201 and engage the thermal fuse, eliminating the need for an operator to manually apply continuous pressure to maintain the position of the annular clamp 400. After the thermal fuse passes through the feed shaft 300 and the straightening guide channel 202 and enters the first annular groove 201 and circles once, the external force on the operating portion 402 is released. The elastic force of the first elastic member 500 pushes the annular clamp 400, causing the protrusion 401 to quickly and stably engage the wave groove of the thermal fuse, achieving automatic fixation of the thermal fuse and improving fixation efficiency and stability.

[0088] The operating portion 402 extends through the inner wall of the mold roller 200 and into the hollow interior, providing a convenient interface for the operator. The operator can use the operating portion 402 to easily overcome the elastic force of the first elastic member 500 and slide the annular clamp 400 from the first annular groove 201 back into the first annular accommodating space 203. This allows for flexible control of the position of the annular clamp 400 when necessary, such as cleaning the mold roller 200 or replacing the thermal fuse. This ensures both automatic securing and operational flexibility and controllability.

[0089] In some examples, the mold roller 200 also has a second annular groove 204, which is located on the side of the first annular groove 201 away from the first annular accommodating space 203. There is a connecting port 205 between the second annular groove 204 and the first annular groove 201, and they are connected through the connecting port 205, so that the thermal fuse can wrap around the first annular groove 201 once and then wrap around the second annular groove 204 once.

[0090] For example, Figure 4 As shown, the second annular groove 204 is also located at the end of the mold roller 200, on the side of the first annular groove 201 away from the first annular accommodating space 203. Its shape is the same as the first annular groove 201, an annular structure, with the same inner diameter as the first annular groove 201. The depth and width of the second annular groove 204 are consistent with those of the first annular groove 201, ensuring the same placement and fixation of the thermal fuse in the two grooves.

[0091] The communication opening 205 is a passage connecting the first annular groove 201 and the second annular groove 204 . The width of the communication opening 205 is slightly larger than the diameter of the thermal fuse to ensure that the thermal fuse can pass through smoothly.

[0092] To ensure that the thermal fuse can smoothly pass from the first annular groove 201 through the communication opening 205 into the second annular groove 204, a guide block can be provided on the side of the communication opening 205 near the first annular groove 201 to guide the thermal fuse accurately into the communication opening 205. The guide block is triangular in shape, with its hypotenuse tangent to the inner wall of the first annular groove 201 and its right-angled side aligned with one side of the communication opening 205, guiding the thermal fuse to smoothly transition into the communication opening 205.

[0093] By providing the second annular groove 204 and connecting it to the first annular groove 201, the thermal fuse can continue around the second annular groove 204 after completing one loop around the first annular groove 201, increasing the amount of thermal fuse embedded in the socket of the carat tube. More thermal fuses mean stronger connection strength during the subsequent electrofusion process, improving the stability and reliability of the carat tube connection. Furthermore, the double-groove winding method ensures a more even distribution of the thermal fuses on the mold roller 200, reducing the potential for local overheating or poor connection problems caused by the concentration of thermal fuses in one place.

[0094] The design of the communication port 205 and the guide block provides a smooth passage and precise guidance for the thermal fuse from the first annular groove 201 into the second annular groove 204. The guide block guides the thermal fuse precisely into the communication port 205, preventing it from twisting or jamming during entry. The smooth chamfering of the communication port 205 further reduces resistance to the passage of the thermal fuse, ensuring smooth winding between the two annular grooves and improving the smoothness and stability of the production process.

[0095] One end of the mold roller 200 may have an annular ridge 250. The annular ridge 250 is used to increase the diameter of one end of the molded carat tube to facilitate insertion of the other end of another carat tube into the same end. The first annular groove 201 and the second annular groove 204 are also formed on the annular ridge 250, so that the thermal fuse is located on the inner wall of the carat tube end with the larger diameter.

[0096] In some examples, the second annular groove 204 has a second annular accommodating space 206 on the side away from the first annular groove 201, and an annular clamp 400 is also slidably arranged in the second annular accommodating space 206 for clamping the thermal fuse wound in the second annular groove 204. It also includes a second elastic member 600, and one end of the second elastic member 600 acts on the annular clamp 400 in the second annular accommodating space 206, and the other end acts on the mold roller 200, providing a force for the annular clamp 400 in the second annular accommodating space 206 to slide closer and cause the protrusion 401 to slide to the second annular groove 204.

[0097] For example, Figure 2 As shown, the second annular accommodating space 206 is located on the side of the second annular groove 204 away from the first annular groove 201. Its shape is similar to the first annular accommodating space 203 and is an annular structure. The inner diameter of the second annular accommodating space 206 is consistent with the inner diameter of the second annular groove 204, and provides sufficient sliding space for the annular clamp 400.

[0098] The annular clamp 400 slidably disposed in the second annular accommodating space 206 has the same structure as the annular clamp 400 in the first annular accommodating space 203. The protrusion 401 has the same size and shape as the protrusion 401 of the annular clamp in the first annular accommodating space 203 and is used to be clamped in the wave groove of the wave-shaped thermal fuse.

[0099] The second elastic member 600 is a spring bar of the same type as the first elastic member 500. One end of the second elastic member 600 is pressed against the side of the annular clamp 400 in the second annular accommodating space 206 close to the second annular groove 204, and the other end is pressed against the inner wall of the mold roller 200 at the corresponding position of the second annular accommodating space 206.

[0100] A second annular accommodating space 206, equipped with an annular clamp 400 and a second elastic member 600, is provided on one side of the second annular groove 204, further strengthening the fixation of the thermal fuse wound within the second annular groove 204. Similar to the fixing structure in the first annular groove 201, the second elastic member 600 provides a continuous elastic force to the annular clamp 400, allowing the protrusion 401 of the annular clamp 400 to tightly engage the corrugated groove of the thermal fuse. This dual fixing structure ensures that the thermal fuse remains stable and prevents displacement within the second annular groove 204 during all stages of the carat tube processing, especially when the mold roller 200 rotates or is subjected to vibration, thereby ensuring the accuracy and reliability of the pre-embedded thermal fuse.

[0101] The design of the annular clamping member 400 and second elastic member 600 within the second annular accommodating space 206 is consistent with the structure within the first annular accommodating space 203, ensuring consistency during operation. Whether securing the thermal fuse within the first annular groove 201 or the second annular groove 204, the operation is identical, reducing operator learning costs and the risk of operational errors. This design also facilitates equipment maintenance and management. If a problem with the annular clamping member 400 or elastic member occurs, the same spare part can be used for replacement, improving maintenance efficiency.

[0102] In some examples, the mold roller 200 includes a first roller flap 210 and a second roller flap 220, one end of the first roller flap 210 is hinged to one end of the second roller flap 220, and there is a gap between the other end of the first roller flap 210 and the other end of the second roller flap 220. The third roller flap 230 is relatively slidably arranged on the first roller flap 210, and can block the gap after sliding, so that the first roller flap 210, the second roller flap 220 and the third roller flap 230 are surrounded by a cylindrical shape.

[0103] For example, Figure 2 、 Figure 5 and Figure 7 As shown, one end of the first roller flap 210 and the second roller flap 220 are hinged by a pin shaft, and connecting ear plates with through holes are respectively provided at the hinged ends of the first roller flap 210 and the second roller flap 220, and the pin shaft passes through these through holes to connect the two together.

[0104] Two parallel guide rails are provided on the first roller petal 210 to ensure that the third roller petal 230 can slide smoothly on the first roller petal 210 .

[0105] When the third roller petal 230 slides to block the gap between the first roller petal 210 and the second roller petal 220, the first roller petal 210, the second roller petal 220 and the third roller petal 230 form a cylindrical structure, the outer diameter of which is the formed inner diameter of the carat tube.

[0106] The hinged structure of the first and second roller lobes 210, 220, and the sliding structure of the third roller lobes 230 facilitate demolding of the mold roller 200 after the carat tube is wound and formed. By opening the third roller lobes 230, the first and second roller lobes 210, 220 are spread apart around the hinge point, reducing the outer profile of the mold roller 200 and making it easier to remove the carat tube from the mold roller 200. This design avoids damage to the carat tube during the demolding process, potentially resulting from traditional molds, thereby improving demolding efficiency and product quality.

[0107] Among them, considering that the mold roller 200 is divided into the first roller lobe 210, the second roller lobe 220 and the third roller lobe 230 as a whole, the corresponding annular clamp 400 is also divided into three disconnected parts, and each part can be installed with its own operating part 402. Of course, the operating part 402 is not a necessary structure. The annular clamp 400 itself is an exposed structure and can be pushed directly by hand. It can be pushed without the operating part 402, but connecting the operating part 402 will be more convenient for hand pushing.

[0108] The attached figure shows that the first elastic member 500 is an elastic bar. When the mold roller 200 is divided into three parts: the first roller petal 210, the second roller petal 220 and the third roller petal 230, the corresponding annular clamp 400 is also divided into three disconnected parts. The elastic bar should also be divided into multiple, independent elastic bars to avoid affecting the division of the mold roller 200 into three parts.

[0109] In some examples, a nut 700 is further included, which is disposed on the inner wall of the third roller lobe 230, a screw rod 800 is rotatably disposed on the first roller lobe 210 and is threadedly connected to the nut 700, an operating rod 900 is rotatably disposed on the first roller lobe 210, and a length direction of the operating rod 900 is parallel to the axial direction of the mold roller 200, and the operating rod 900 is transmission-connected to the screw rod 800 through a bevel gear.

[0110] For example, Figure 5 、 Figure 7 As shown, the nut 700 is processed into an internal thread structure adapted to the screw rod 800 , and the nut 700 is fixed on the inner wall of the third roller petal 230 .

[0111] One or both ends of the screw rod 800 are mounted via bearings on an oblique support rod 211 extending from the inner wall of the first roller 210. The length of the screw rod 800 is designed according to the structure of the mold roller 200 to ensure that one end can effectively engage with the nut 700 and the other end is connected to the operating rod 900 via a bevel gear transmission.

[0112] The operating rod 900 is rotatably mounted on the first roller 210 via a seat bearing. The seat of the seat bearing is fixed to the first roller 210, ensuring that the operating rod 900 can flexibly rotate around its own axis. The length direction of the operating rod 900 is parallel to the axial direction of the mold roller 200. One end is the operating end, which can be Figure 9 As shown, it is located inside the mold roller 200, and the operating end can also extend out of the mold roller 200 to facilitate the operator to hold and operate.

[0113] Bevel gears meshing with each other are mounted on the operating rod 900 and on the end of the screw rod 800 near the operating rod 900. This allows the operator to rotate the operating rod 900 with relatively little force to achieve a relatively large torque output from the screw rod 800, thereby easily driving the third roller 230 to slide.

[0114] The threaded connection between the nut 700 and the screw 800 converts the rotation of the operating lever 900 into linear motion of the third roller 230, enabling precise control of the position of the third roller 230. By properly designing the thread pitch, the movement distance of the third roller 230 can be precisely adjusted according to actual needs, thereby achieving a cylindrical structure formed by the mold rollers 200 for the carat tube winding production process.

[0115] When the mold roller 200 completes the processing of the carat tube and needs to be demolded, considering that the third roller petal 230 and the adjacent first roller petal 210 and second roller petal 220 are in a tight state and have a certain abutting force, it will affect the movement of the third roller petal 230 and move it away from the first roller petal 210 and second roller petal 220, so that the rotation operation of the operating rod 900 requires a large initial operating force. For this reason, it can be designed that the abutting surface 240 of the third roller petal 230 and the first roller petal 210 and second roller petal 220 is oblique to the radial direction of the mold roller 200, thereby greatly reducing the separation resistance of the first roller petal 210 and second roller petal 220 on the third roller petal 230, making demolding more convenient.

[0116] The operating lever 900 is connected to the screw 800 via a bevel gear. The bevel gear's transmission ratio amplifies force. The operator simply applies a small amount of force to rotate the operating lever 900, which, through the bevel gear transmission, generates a large torque on the screw 800, easily driving the third roller 230 to slide on the first roller 210. This design reduces operator workload and improves operational convenience.

[0117] The nut 700 is set on the inner wall of the third roller lobe 230, the screw rod 800 is rotatably set on the first roller lobe 210, and the operating rod 900 is rotatably set on the first roller lobe 210 parallel to the axial direction of the mold roller 200. This layout makes the entire driving structure compact and occupies little space without affecting other functions of the mold roller 200.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all of these should be included in the scope of the claims of the present disclosure.
