Description

Technical Field

[0001] This invention relates to the field of bathtub production equipment technology, specifically to an edge rounding forming and pressing device for bathtub production. Background Technology

[0002] During the manufacturing process of bathtubs, resin and fiberglass layers are typically sprayed onto their exterior to improve the overall structural strength and load-bearing capacity. Especially in the corner areas of the bathtub's edge, where curvature varies significantly, the fiberglass is prone to accumulating, lifting, or unevenly adhering after spraying. Therefore, it is usually necessary to manually apply and press the fiberglass at the edges repeatedly using rollers or scrapers to ensure the fiberglass fully adheres to the bathtub's corners and forms a rounded corner structure.

[0003] In existing technologies, the glass fiber lamination process for the rounded corners of bathtub edges is mostly done manually. Operators need to continuously adjust the lamination angle and pressure according to the bathtub's edge contour to gradually adhere the glass fiber to the curved surface. However, this processing method still has several shortcomings in actual production: Firstly, due to the continuous curved surface and corner structure of the edge area, it is difficult to maintain uniform force during manual lamination, which can easily lead to localized glass fiber accumulation, air bubbles, or inconsistent thickness, thus affecting the edge forming quality. Secondly, before the glass fiber and resin are fully cured, the edge area is prone to springback, warping, or wrinkling due to unstable lamination, affecting the subsequent structural strength and appearance flatness. Furthermore, manual operation relies heavily on worker experience, resulting in poor consistency between different operators and making it difficult to guarantee the edge rounding effect of batch products. At the same time, prolonged manual lamination is labor-intensive, has low processing efficiency, and is not conducive to continuous production. Summary of the Invention

[0004] To address the aforementioned problems, an edge rounding forming and pressing device for bathtub production is provided. By proposing a device capable of performing comprehensive, continuous, and uniform pressure pressing on the rounded corners of bathtubs, the technical problems of uneven fiberglass bonding, poor edge forming consistency, and low efficiency of manual pressing in the prior art are solved.

[0009] Preferably, the drive unit further includes a pressure sensor capable of real-time detection of the spring's supporting pressure; the pressure sensor is coaxially disposed at one end of the guide cylinder near the guide roller and abuts against the spring.

[0010] Preferably, the adjustment unit is provided with a fixing frame and an electric push rod capable of dynamically adjusting the driving pressure of the drive unit; the electric push rod is fixedly mounted on the drive unit by the fixing frame.

[0011] Preferably, the pressing unit includes a mounting frame and pressing brushes disposed opposite to each other at both ends of the mounting frame and capable of longitudinal sliding adjustment, as well as locking members capable of limiting and locking the pressing brushes; there are two pressing brushes, which are slidably disposed opposite to each other at both ends of the mounting frame; there are two locking members, which are respectively locked onto the two pressing brushes to lock the pressing brushes onto the mounting frame.

[0013] The advantages of this invention compared to the prior art are: 1.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] See Figures 1 to 8 As shown: A rounded corner forming and pressing device for bathtub production, used to press the rounded corners of bathtubs, includes: a frame 1; a drive module 2, the drive module 2 being vertically fixed on the frame 1, the drive module 2 having a drive part 21 capable of rotating around the rounded corners of the bathtub; a pressing module 3, the pressing module 3 being fixed on the drive part 21; the pressing module 3 having a pressing unit 31 capable of dynamically pressing along the rounded corners of the bathtub and a drive unit 32 capable of driving the pressing unit 31 to dynamically fit against the outer wall of the rounded corners of the bathtub; when the pressing unit 31 is driven to press the rounded corners of the bathtub, the pressing unit 31 can be driven by the drive unit 32 to uniformly press against the outer wall of the bathtub in real time.

[0027] After the bathtub moves to the corresponding station of the drive module 2 under the conveying action of the external transmission device, the position of the rounded corner area of ​​the bathtub edge is first calibrated so that the area to be pressed corresponds to the rolling trajectory of the pressing unit 31. Then, the pressing unit 31 is driven to move. By adjusting the installation angle and rolling end posture of the pressing unit 31, the rolling end can form a preset fitting angle with the outer wall of the rounded corner of the bathtub edge, avoiding local force deviation during the pressing process. After the pressing unit 31 is adjusted, the rolling end is driven to slowly approach and form a pre-pressed contact with the outer wall of the bathtub. Then, the drive unit 32 and drive module 2 are started simultaneously, so that the pressing unit 31 moves continuously along the contour of the bathtub edge. During the movement, the glass fiber layer sprayed on the rounded corner area is continuously rolled and compacted, so that the glass fiber and the curved surface of the bathtub edge gradually fit together and form a stable rounded corner structure until the continuous pressing and shaping of the entire edge area is completed.

[0028] See Figure 2 As shown: The pressing module 3 further includes an adjustment unit 33 that can dynamically adjust the pressing pressure of the pressing unit 31 in real time; the driving unit 32 and the pressing unit 31 are coaxially fixedly arranged on the driving end of the adjustment unit 33.

[0029] When the pressing unit 31 and the driving unit 32 move along the outer wall of the bathtub under the drive of the driving module 2, the pressing unit 31 first forms a stable contact with the outer wall of the bathtub under the thrust output by the driving unit 32. Since the rounded corner area of ​​the bathtub edge usually has curvature and height changes, the reaction force received by the pressing unit 31 at different pressing positions will change dynamically, which will cause the output load of the driving unit 32 to fluctuate. In order to avoid inconsistent pressing pressure due to local curvature changes, the adjustment unit 33 will collect the output driving force of the driving unit 32 at different stages in real time, and dynamically compensate and adjust the driving force difference according to the detection results, so that the pressing unit 31 always maintains a relatively constant pressing pressure at different trajectory positions, thereby avoiding the problem of insufficient pressing or excessive compression in local areas.

[0030] See Figures 5 to 8 As shown: The drive unit 32 is provided with a guide roller 321 that can continuously limit the pressing stroke of the pressing unit 31, a telescopic rod 322 that can drive the guide roller 321 to abut against the outer wall of the bathtub, a spring 323 that can drive the telescopic rod 322 to extend elastically, and a guide cylinder 324 that can guide the telescopic rod 322 to slide axially; the telescopic rod 322 is coaxially slidably disposed in the guide cylinder 324; the guide roller 321 is disposed at the front end of the telescopic rod 322; the spring 323 is coaxially sleeved and installed on the outside of the telescopic rod 322 and its two ends abut against the guide roller 321 and the guide cylinder 324 respectively.

[0031] When the outer wall of the bathtub is rolled and pressed by the pressing unit 31, the guide roller 321 will first form a flexible contact with the outer wall of the bathtub under the continuous elastic force of the spring 323, so that the guide roller 321 can fit the edge contour of the bathtub in advance. Then, driven by the drive module 2, the guide roller 321 will continue to roll along the preset rounded corner trajectory, and in the rolling process, it will pre-guide and initially compact the glass fiber sprayed on the edge area. Since the pressing unit 31 is located on one side of the front end of the drive unit 32, in the process of the guide roller 321 rolling along the outer wall, its contact trajectory and displacement change will synchronously drive the pressing stroke of the pressing unit 31 to adaptively adjust, so that the subsequent pressing structure can always fit the curvature change of the bathtub edge, thereby ensuring that the pressing unit 31 always presses the rounded corner area evenly with a stable stroke throughout the rolling process.

[0032] See Figures 5 to 8 As shown: The drive unit 32 further includes an adjusting ring 325 capable of self-adjusting the moving direction of the guide roller 321, a locking pin 326 capable of locking the adjusting ring 325 and the guide cylinder 324, and a limiting ring 327 capable of preventing the telescopic rod 322 from disengaging from the guide cylinder 324; the adjusting ring 325 is coaxially rotatably disposed outside the guide cylinder 324; the locking pin 326 is radially inserted and pulled out of the side wall of the adjusting ring 325; the limiting ring 327 is slidably sleeved and installed outside the telescopic rod 322 and disposed near the end of the telescopic rod 322.

[0033] The drive unit 32 further includes a connecting frame 328 that can connect the adjusting ring 325 and the adjusting unit 33; the adjusting ring 325 is connected to the adjusting unit 33 through the connecting frame 328; the outer wall of the guide cylinder 324 is also radially provided with locking holes for the locking pin 326 to be inserted, and a plurality of locking holes are arranged circumferentially along the axis of the guide cylinder 324.

[0034] When the rolling direction of the guide roller 321 needs to be adjusted, the operator only needs to pull out the locking pin 326 to release the telescopic rod 322 from its limiting state; then rotate the telescopic rod 322 to drive the front guide roller 321 to change its orientation angle synchronously until the guide roller 321 is adjusted to the position corresponding to the target pressing trajectory and then stops rotating; then reinsert the locking pin 326 to lock the telescopic rod 322 again, thereby realizing the rapid adjustment of the guiding direction of the guide roller 321. The locking pin 326 and the limiting ring 327 are preferably connected by magnetic attraction, so that the locking pin 326 can be quickly attracted and positioned during disassembly and assembly, improving the adjustment efficiency; at the same time, the limiting ring 327, which is slidably set at the end of the telescopic rod 322, is used to limit the maximum extension stroke of the telescopic rod 322 in real time, preventing the telescopic rod 322 from detaching from the guide cylinder 324 under the continuous pushing action of the spring 323, thereby ensuring the stability of the adjustment process and the structural safety.

[0035] See Figure 7 and Figure 8 As shown: The drive unit 32 further includes a pressure sensor 329 capable of real-time detection of the supporting pressure of the spring 323; the pressure sensor 329 is coaxially disposed at one end of the guide cylinder 324 near the guide roller 321 and abuts against the spring 323.

[0036] By setting a pressure sensor 329, the contact pressure between the guide roller 321 and the outer wall of the bathtub can be detected in real time during the dynamic support and rolling process of the guide roller 321, and the detection data is fed back to the adjustment unit 33. This ensures that the guide roller 321 maintains a low and stable contact pressure while meeting the trajectory guidance requirements, avoiding local accumulation, wrinkles or warping of the glass fiber layer during the rolling process due to excessive support pressure. At the same time, the adjustment unit 33 dynamically corrects the initial position of the limiting ring 327, so that the compression of the spring 323 can change synchronously with the real-time displacement of the guide roller 321, thereby realizing dynamic limit control of the support elasticity of the spring 323.

[0037] See Figure 2 and Figure 3 As shown: The adjustment unit 33 is provided with a fixing frame 331 and an electric push rod 332 that can dynamically adjust the driving pressure of the drive unit 32; the electric push rod 332 is fixedly mounted on the drive part 21 through the fixing frame 331.

[0038] The pressure sensor 329 is electrically connected to the electric push rod 332. When the pressing unit 31 presses the edge of the bathtub, the supporting pressure applied by the spring 323 to the guide roller 321 is collected in real time by the pressure sensor 329 and transmitted to the electric push rod 332. The electric push rod 332 automatically adjusts the initial position of the guide cylinder 324 according to the received pressure change information, thereby changing the pre-compression of the spring 323, so that the spring 323 can apply a relatively constant supporting pressure to the guide roller 321 in different pressing trajectory stages. This ensures that the guide roller 321 can stably fit against the outer wall of the bathtub in different curvature areas and avoid pressure fluctuations during the pressing process.

[0039] See Figure 4 and Figure 8 As shown: The pressing unit 31 is provided with a mounting bracket 311 and pressing brushes 312 that are disposed opposite to each other at both ends of the mounting bracket 311 and can be adjusted longitudinally, and locking members 313 that can limit and lock the pressing brushes 312; there are two pressing brushes 312, which are slidably disposed opposite to each other at both ends of the mounting bracket 311; there are two locking members 313, which are respectively locked onto the two pressing brushes 312 to lock the pressing brushes 312 onto the mounting bracket 311.

[0040] Each of the pressing brushes 312 is also fixedly provided with a liquid supply chamber 314 on one side, which is capable of supplying liquid to the pressing brush 312.

[0041] By adjusting the longitudinal travel of the pressing brush 312 on the mounting bracket 311, the contact pressure between the pressing brush 312 and the outer wall of the bathtub can be adjusted according to different thicknesses of glass fiber layers and different pressing requirements, so that the pressing brush 312 can form different degrees of compaction effect during operation. When it is necessary to adjust the position of the pressing brush 312, it is only necessary to release the locking member 313 to adjust the pressing brush 312 in the free state to the preset height position and then lock it again to adapt to the pressing requirements of different edge areas. At the same time, the liquid supply chamber 314 can continuously provide auxiliary liquid to the inside or surface of the pressing brush 312, so that the pressing brush 312 remains moist during the pressing process, thereby reducing the adhesion and pulling of glass fibers during the pressing process.

[0042] See Figure 1 and Figure 2As shown: The drive module 2 includes a first linear actuator 22 capable of driving the pressing module 3 to rotate circumferentially along the rounded corner of the bathtub and a second linear actuator 23 capable of driving the pressing module 3 to slide longitudinally; the second linear actuator 23 is fixedly disposed vertically at the drive end of the first linear actuator 22; the drive part 21 is fixedly disposed at the drive end of the second linear actuator 23.

[0043] By setting a first linear actuator 22 and a second linear actuator 23 that can drive the pressing module 3 to move horizontally and vertically respectively, the pressing module 3 can be adjusted in multiple directions. The first linear actuator 22 is used to drive the pressing module 3 to move along the edge of the bathtub, and the second linear actuator 23 is used to adjust the bonding depth and height between the pressing module 3 and the outer wall of the bathtub, so that the pressing unit 31 can continuously bond to rounded corner areas with different curvatures during the movement. Under the coordinated drive of the two sets of linear actuators, the pressing module 3 can adjust its posture in real time according to the changes in the contour of the bathtub edge, so as to achieve continuous pressing in multiple angles and directions.

[0044] This invention not only enables dynamic and comprehensive pressing according to the edge shape of the bathtub, but also keeps the pressing pressure within a preset threshold range in different curvature areas of the bathtub, avoiding uneven local stress that could lead to fiberglass layer buildup or warping.

[0045] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
