Description

Technical Field

[0001] This invention relates to the field of pressure molding technology for plastic materials, and in particular to a continuous inlay strip manufacturing apparatus and a continuous inlay strip manufacturing method. Background Technology

[0002] Continuous inlay strips are typically used to form continuous decorative / functional embedded structures on a substrate surface. The typical processing requires applying a stable pressing force to the strip blank and reliably imprinting the predetermined pattern onto the surface to obtain a continuous, clear, and consistent flow channel texture. In actual production, to improve efficiency, the industry tends to use a roller-press continuous forming method, where the strip blank passes continuously between the pressure roller and the forming roller to complete the imprinting process.

[0003] However, existing continuous forming solutions still have several prominent problems: First, the forming gap between the pressure roller and the forming roller is difficult to adjust conveniently and stably, leading to fluctuations in the pressing pressure, which in turn causes inconsistent imprint depth, unclear patterns, or local distortion; Second, the strip blank is prone to lateral displacement or deviation during the pressing process, resulting in misalignment of the pattern imprint position and uneven edge forming, affecting the consistency and yield of the finished product; Third, the forming roller mold plate is prone to heat accumulation during continuous imprinting. If there is a lack of effective circulating cooling and a reliable dynamic-static connection structure, the temperature of the mold plate is difficult to control, which can easily lead to decreased imprinting stability, increased risk of adhesion / deformation, and may cause problems such as entanglement of cooling pipes and unreliable connections, resulting in frequent downtime for maintenance.

[0004] Therefore, a continuous inlay strip manufacturing device is needed that can achieve adjustable and stable control of the wheel gap during continuous roller pressing, effectively guide and limit the strip blank to suppress lateral deviation, and reliably circulate and cool the forming wheel mold plate while maintaining stable connection with the external cooling pipeline when the forming wheel rotates, thereby improving the clarity of the embossed pattern and the consistency of the finished product, and reducing downtime maintenance costs. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a continuous inlay strip manufacturing apparatus and method. A pressure roller and a forming roller are positioned opposite each other to form a gap for pressure extrusion molding. A pressure regulating device allows the pressure roller to be moved to adjust the gap, achieving controllable and stable pressure on the strip blank. A groove is provided on the pressure roller disc to accommodate and position the strip blank, and guide and limiting parts are provided on both sides of the groove to constrain the lateral deviation of the strip blank during the pressure extrusion process, reducing pattern position deviation and uneven edge forming caused by misalignment. A circulating cooling path is provided on the forming roller, and a rotary joint is used to maintain communication with the external cooling medium pipeline during rotation, ensuring a stable temperature of the mold disc during continuous imprinting. This suppresses imprint quality fluctuations and adhesion / deformation risks caused by heat accumulation, while also reducing cooling pipe entanglement and downtime maintenance, improving continuous production stability and efficiency.

[0006] To achieve the above objectives, the present invention provides a continuous inlay strip manufacturing apparatus, comprising a pressure roller and a forming roller; The pressure roller is arranged opposite to the forming roller, and a roller gap is formed for pressing and extruding the strip blank. The pressure roller is mounted on a pressure regulating device to adjust the roller gap; The pressure roller includes a pressure roller disc and a pressure roller shaft. The pressure roller disc is provided with a groove for accommodating and positioning the strip blank in the gap between the rollers, and guide and limiting portions are provided on both sides of the groove to limit the lateral displacement of the strip blank during the pressing and extrusion process. The forming wheel includes a mold plate, and the outer peripheral surface of the mold plate is engraved with a labyrinth flow pattern to imprint the labyrinth flow pattern onto the strip blank when the strip blank is in the gap of the wheel and is subjected to pressure to form a continuous inlaid strip. The forming wheel also includes a circulating cooling passage for circulating cooling of the mold plate and a rotary joint connected to the circulating cooling passage. The circulating cooling passage includes a cooling medium inlet and a cooling medium outlet. The rotary joint is used to maintain communication with an external cooling medium pipeline when the forming wheel rotates.

[0007] In the above technical solution, preferably, the pressure regulating device is used to make the position of the pressure roller movable to change the wheel gap between the pressure roller and the forming roller, wherein the position movable means driving the pressure roller to move in a direction closer to or away from the forming roller to adjust the pressure applied to the strip blank within the wheel gap.

[0008] In the above technical solution, preferably, the pressure roller shaft is connected to a power device so that it rotates around the axis under the drive of the power device.

[0009] In the above technical solution, preferably, the guide limiting part protrudes radially relative to the bottom of the groove, and the groove is located in the radial center of the pressure roller disc.

[0010] In the above technical solution, preferably, the forming wheel further includes a front sealing disc, a rear sealing disc, an intermediate flange, a connecting flange, and a forming wheel shaft; The mold plate is located between the front sealing plate and the rear sealing plate; The intermediate flange is fixed to the rear sealing plate and is provided with an inlet interface and a loop interface that are connected to the circulating cooling passage. The connecting flange is fixed to the intermediate flange and connected to the forming wheel shaft, so that when the forming wheel shaft rotates, it drives the front sealing plate, the mold plate, the rear sealing plate and the intermediate flange to rotate synchronously.

[0011] In the above technical solution, preferably, the mold plate is provided with an inlet and a loop that are connected to the inlet interface and the loop interface, and a water baffle is provided inside the mold plate to form a cooling medium flow channel; The front and rear sides of the mold plate are provided with connecting holes, which are used to connect the inlet, the outlet and the cooling medium flow channel.

[0012] In the above technical solution, preferably, the intermediate flange is provided with a sealing groove, and a sealing ring is installed in the sealing groove. The sealing ring cooperates with the mold plate to form a sealed space so that the cooling medium circulates between the inlet and the outlet.

[0013] In the above technical solution, preferably, the forming wheel shaft is mounted on the machine base by bearings and connected to a power device so that it rotates around the axis under the drive of the power device.

[0014] In the above technical solution, preferably, the mold plate is detachably installed between the front sealing plate and the rear sealing plate.

[0015] The present invention also proposes a method for manufacturing a continuous inlay strip, applicable to the continuous inlay strip manufacturing apparatus disclosed in any of the above technical solutions, comprising: The strip blank is fed into the gap between the pressure roller and the forming roller in the continuous inlay strip making device; The wheel gap is adjusted by a pressure regulating device so that the strip blank is subjected to counter-pressure when passing through the wheel gap; The forming wheel is driven to rotate, so that the labyrinth flow pattern on the outer periphery of the mold plate is continuously imprinted onto the strip blank during the movement of the strip blank, so as to form a continuous inlaid strip. During the imprinting process, the cooling medium circulates through the cooling circulation channel and is connected to the external cooling medium pipeline through the rotary joint to circulate and cool the mold plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The gap between the pressure roller and the forming roller is formed by the relative arrangement of the pressure roller and the forming roller. The pressure adjustment device allows the pressure roller to be moved to adjust the gap, thereby achieving controllable and stable output of the pressure, so that the strip blank can obtain consistent forming conditions during continuous passage, thereby improving the consistency and clarity of the labyrinth flow pattern imprint and reducing the risk of uneven imprint depth and local distortion.

[0017] (2) By setting a groove for accommodating and positioning the strip blank on the pressure roller disc, and setting guide limiting parts on both sides of the groove, the lateral offset of the strip blank during the pressing and extrusion process is constrained, reducing defects such as pattern position offset and uneven edge forming caused by deviation, improving the dimensional consistency and yield of the finished product, and reducing rework and scrap costs.

[0018] (3) By setting up a circulating cooling path on the forming wheel and cooperating with a rotary joint, the forming wheel is kept connected to the external cooling medium pipeline while rotating, so that the mold plate maintains a stable temperature during continuous imprinting, suppressing the imprinting quality fluctuation and adhesion / deformation risk caused by heat accumulation. At the same time, it avoids problems such as cooling pipe entanglement and unreliable connection, reduces the frequency of downtime maintenance and improves the stability and efficiency of continuous production.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings: like Figures 1 to 4 As shown, a continuous inlay strip manufacturing apparatus according to the present invention is used to continuously press and extrude the strip blank, and form a continuous labyrinth flow channel imprint structure on the surface of the strip blank.

[0023] The device includes a pressure roller 1 and a forming roller 2, which are arranged opposite to each other and form a gap between the rollers for pressing and extruding the strip blank. The strip blank enters the gap between the rollers during continuous conveying and is pressed and formed under the action of pressing and extrusion.

[0024] The pressure roller 1 is mounted on the pressure regulating device 3. The pressure regulating device 3 adjusts the gap between the pressure roller 1 and the forming roller 2, which can adjust the extrusion pressure on the strip blank, so that the strip blank can obtain a stable forming pressure range within the gap, thereby supporting the clarity and consistency of the labyrinth flow channel imprint.

[0025] The pressure roller 1 includes a pressure roller disc 11 and a pressure roller shaft 12. In order to suppress the lateral displacement of the strip blank during the pressing and extrusion process, the pressure roller disc 11 is provided with a groove for accommodating and positioning the strip blank in the gap between the rollers, and guide limiting parts are provided on both sides of the groove so that the strip blank passes through the groove and is constrained by the limiting parts on both sides, thereby reducing the imprint position displacement and uneven edge forming caused by lateral displacement.

[0026] The forming wheel 2 includes a mold disk 22. The outer peripheral surface of the mold disk 22 is engraved with a labyrinth flow pattern 226 so that when the strip blank is in the wheel gap and is subjected to pressure, the labyrinth flow pattern 226 is pressed onto the strip blank to form a continuous inlaid strip, realizing continuous processing of the strip while moving and printing the labyrinth flow.

[0027] Considering the high temperature requirements of the sticker and the fact that temperature fluctuations can easily affect the imprinting quality, the forming wheel 2 also includes a circulating cooling passage for circulating cooling of the mold plate 22 and a rotary joint 27 connected to the circulating cooling passage. The circulating cooling passage includes a cooling medium inlet 29 and a cooling medium loop 28. The rotary joint 27 is used to maintain communication with the external cooling medium pipeline when the forming wheel 2 rotates, so that the forming wheel 2 remains connected to the external cooling medium pipeline while rotating, thereby circulating and cooling the mold plate 22 and maintaining its temperature stability, while preventing the external pipeline from getting tangled during rotation.

[0028] During implementation, water cooling can be used to control the temperature of the mold plate 22. A rotary joint 27 is installed at the tail of the forming wheel shaft 26, and a cooling medium circuit 28 and a cooling medium inlet 29 are installed on the rotary joint 27. This ensures that the water inlet pipe and the water return pipe do not rotate with the forming wheel shaft 26 when it rotates.

[0029] In this embodiment, a clear labyrinth flow channel imprint structure is stably obtained under continuous processing conditions, while taking into account both operational stability and ease of maintenance.

[0030] In the above embodiment, preferably, the pressure regulating device 3 is used to make the position of the pressure roller 1 movable, so as to change the wheel gap between the pressure roller 1 and the forming roller 2, wherein the position is movable to drive the pressure roller 1 to move in a direction closer to or farther from the forming roller 2. Through this directional displacement adjustment, the wheel gap can be set to a target range under different strip blank states and different forming conditions, so that the pressure exerted on the strip blank within the wheel gap remains controllable, supporting the labyrinth flow channel imprint to achieve a clearer state and reducing imprint fluctuations.

[0031] In this embodiment, the wheel gap adjustment path is clear, the pressure conditions are controllable, and the clarity and consistency of the imprint are improved.

[0032] In the above embodiment, preferably, the pressure roller shaft 12 is connected to a power device so that it rotates around the axis under the drive of the power device. The rotation of the pressure roller 1 cooperates with the continuous conveying of the strip blank, so that the strip blank is subjected to more stable force when it enters the wheel gap, avoiding the fluctuation of the forming state caused by contact dragging, and helping the strip blank to maintain a stable posture as it passes through the wheel gap under the constraint of the groove and the guide limiting part.

[0033] In this embodiment, the strip blank passes through the wheel gap more continuously and smoothly, resulting in better consistency in the molding process.

[0034] In the above embodiment, preferably, the guide limiting part protrudes radially relative to the bottom of the groove, and the groove is located in the radial center of the pressure roller disk 11.

[0035] This structure corresponds to the wheel surface shape with a concave center and convex sides. The strip blank is preferentially accommodated and positioned by the central groove at the wheel gap, and the convex guide limiting parts on both sides provide lateral restraint for the strip blank, thereby suppressing deviation. At the same time, when the wheel gap setting is too small and the pressure increases, this convex structure provides a certain force protection for the contact state between the strip blank and the forming wheel 2, which helps to reduce the risk of wear on the pattern of the forming wheel 2 caused by overpressure.

[0036] In this embodiment, the probability of deviation is reduced, the imprint position is more stable, and the adaptability to overpressure conditions is stronger.

[0037] In the above embodiment, preferably, the forming wheel 2, in addition to the mold plate 22, also includes a front sealing plate 21, a rear sealing plate 23, an intermediate flange 24, a connecting flange 25, and a forming wheel shaft 26. Specifically, the mold plate 22 is located between the front sealing plate 21 and the rear sealing plate 23. The front sealing plate 21 and the rear sealing plate 23 fix and seal the two sides of the mold plate 22 to prevent water leakage. The intermediate flange 24 is fixed to the rear sealing plate 23 and is provided with an inlet interface 241 and a return interface 242 that communicate with the circulating cooling passage. This is used to establish the inlet and return water connection relationship with the external cooling medium pipeline, ensuring that the cooling water can only circulate between the inlet interface 241 and the return interface 242. The connecting flange 25 is fixed to the intermediate flange 24 and keyed to the forming wheel shaft 26 so that when the forming wheel shaft 26 rotates, it drives the front sealing disc 21, the mold disc 22, the rear sealing disc 23 and the intermediate flange 24 to rotate synchronously. Thus, during the rotation of the mold disc 22, the labyrinth flow channel pattern 226 on its outer circumference is continuously pressed onto the strip blank passing through the wheel gap, while ensuring that the circulating cooling passage maintains a stable medium circulation during rotation.

[0038] In this embodiment, the rotating structure of the forming wheel 2 works in conjunction with the cooling connection structure to support continuous pressing and stable temperature control.

[0039] like Figure 5 As shown, in the above embodiment, preferably, the mold plate 22 is provided with an inlet 221 and a loop 222 that are connected to the inlet interface 241 and the loop interface 242, and a water baffle 223 is provided inside the mold plate 22 to form a cooling medium flow channel 224.

[0040] The front and rear sides of the mold plate 22 are provided with connecting holes 225. The connecting holes 225 are used to connect the inlet 221, the outlet 222 and the cooling medium flow channel 224, so that the cooling medium enters the mold plate 22 and flows in a controlled manner in the flow channel formed by the water baffle 223. The internal space of the mold plate 22 is fully covered by the front and rear connecting holes 225, thereby achieving effective heat exchange and temperature stability of the mold plate 22.

[0041] In this embodiment, the cooling medium provides more comprehensive coverage and more uniform heat exchange, resulting in reduced temperature fluctuations in the mold plate 22 and more stable imprinting quality.

[0042] like Figure 6 As shown, in the above embodiment, preferably, the intermediate flange 24 is provided with a sealing groove 243, and a sealing ring is installed in the sealing groove 243. The sealing ring and the mold plate 22 cooperate to form a sealed space so that the cooling medium circulates between the inlet 221 and the outlet 222.

[0043] In this embodiment, the sealing structure is used to limit the leakage path of the cooling medium, ensure that the cooling medium completes the circulation between the inlet and the outlet according to the predetermined circulation path, maintain the effectiveness and stability of the circulating cooling, reduce the risk of water leakage, and improve the stability of the circulating cooling, thereby supporting the constant temperature requirement of the mold plate 22 and reducing downtime maintenance due to cooling failure.

[0044] In the above embodiment, preferably, the forming wheel shaft 26 is mounted on the machine base by bearings and connected to a power unit so that it can rotate around the axis under the drive of the power unit.

[0045] In this embodiment, the bearing support is used to ensure the stability and coaxiality of the rotation of the forming wheel shaft 26, reduce the influence of rotational runout on the stability of the wheel gap, thereby helping to maintain the stability of the pressing conditions of the strip blank in the wheel gap, and keep the labyrinth flow channel imprinting process continuous and consistent, improve rotational stability, reduce wheel gap disturbance, and improve imprinting consistency.

[0046] In the above embodiments, preferably, the mold plate 22 is detachably installed between the front sealing plate 21 and the rear sealing plate 23.

[0047] In this embodiment, after long-term operation of the equipment, the clarity of the labyrinth channel imprint may decrease as the pattern of the mold plate 22 wears down. The mold plate 22 can be quickly disassembled and replaced by a detachable installation method, thereby restoring the imprint clarity without replacing the entire set of forming wheel 2 structure and reducing maintenance costs, shortening maintenance time, and reducing production line downtime losses.

[0048] The present invention also proposes a method for manufacturing a continuous inlay strip, applicable to the continuous inlay strip manufacturing apparatus disclosed in any of the above embodiments, comprising: The strip blank is fed into the gap between the pressure roller 1 and the forming roller 2 in the continuous inlay strip making device; The wheel gap is adjusted by the pressure regulating device 3 so that the strip blank is subjected to pressure and compression when passing through the wheel gap; The driving forming wheel 2 rotates, causing the labyrinth flow pattern 226 on the outer periphery of the mold plate 22 to be continuously imprinted onto the strip blank during the movement of the strip blank, so as to form a continuous inlaid strip. During the imprinting process, the cooling medium circulates through the circulating cooling channel and is connected to the external cooling medium pipeline through the rotary joint 27 to circulate and cool the mold plate 22.

[0049] In this embodiment, the method achieves continuous embossing, the labyrinth channel embossing is clear and stable, and the cooling medium pipeline remains connected under rotation conditions, thus improving operational stability and continuous production efficiency.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
