Description

Technical Field

[0001] This invention belongs to the field of rubber molding, and more specifically, it relates to an intelligent and rapid loading and unloading processing system for rubber sealing rings. Background Technology

[0002] The rubber sealing ring processing system mainly undertakes key processes such as quantitative conveying of rubber materials, precise mold entry, finished product demolding and transfer. Its operational stability and work accuracy directly affect the molding efficiency, dimensional consistency and sealing performance of the sealing ring. The system connects the rubber material pretreatment and vulcanization molding stages through the linkage of mechanical structures, realizing the automated flow from raw material supply to finished product output.

[0003] Existing rubber sealing ring loading and unloading processing systems, for reinforced rubber compounds with added fibers, can only achieve basic material transfer. This can easily lead to localized accumulation and agglomeration of fibers within the rubber compound, resulting in problems such as localized hardening, uneven mechanical properties, and sealing surface defects in the molded sealing ring. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides an intelligent and rapid loading and unloading processing system for rubber sealing rings. The purpose and effectiveness of this system are achieved through the following specific technical means: Its structure includes a fixed frame, a support rod, a loading and unloading assembly, a nozzle, a control box, a motor, and a moving rail. The fixed frame is fixed to the support rod, the loading and unloading assembly is supported and fixed by the support rod, the moving rail is connected to the fixed frame, the support frame is supported between the moving rail and the control box, the control box is connected to the nozzle for control, and the motor controls the support frame to move along the moving rail. The loading and unloading assembly includes a control unit, a pusher pipe, a material bucket, a rotating ring, a connecting frame, a control shaft, a connecting body, a fixed plate, a movable channel, a feed inlet, a conveying channel, a mold plate, a rotating body, movable wheels, and a transmission machine. The control unit is connected to the rotating body via gears. The conveying channel is connected between the pusher pipe and the material bucket. The rotating ring is connected to the fixed plate and is rotatable. The control shaft is installed between the connecting frame and the connecting body. The movable wheel is connected to the movable channel via a toothed connection. The transmission machine is connected to the movable channel. The feed inlet is connected to the material bucket. The mold plate is located between two fixed plates. The connecting body is fastened to the mold plate with bolts and can withstand the radial load when the loading and unloading assembly rotates, ensuring the stability of the structure during operation.

[0005] As a further improvement of the present invention, the push tube includes a limiting channel, a spring, a connecting ring, a connecting channel, an extension rod, a push plate, and a limiting block. The limiting channel and the connecting channel are an integrated structure. The spring is connected between the inner surface of the limiting channel and the limiting block. The extension rod and the push plate are an integrated structure. The limiting block is connected to the push plate. The connecting ring is fixed to the connecting channel. There are two push tubes and they are distributed symmetrically.

[0006] As a further improvement of the present invention, the nozzle can be adjusted to the required angle, the loading and unloading assembly can rotate 180 degrees, the two workstations operate alternately, the support frame moves and adjusts when the loading and unloading assembly rotates to avoid obstructing the rotation path, and the nozzle can accurately spray the release agent as needed.

[0007] As a further improvement of the present invention, the control shaft controls the overall rotation of 180 degrees, the transmission mechanism controls the movable wheel to drive the fixed plate to move along the movable track, the rotating body drives the material bucket, conveying channel, push pipe and rotating ring to rotate at a uniform speed, the rotating ring can rotate along the fixed plate while avoiding the leakage of colloid, the movable wheel and the movable track have tight meshing of teeth, which can realize the smooth movement of the fixed plate without jamming.

[0008] As a further improvement of the present invention, the pusher plate, pushed by the colloid, will pull the limiting block and the spring. The limiting block moves through the opening of the limiting channel and keeps the colloid from flowing out. The upper part of the limiting block is a ring with four arc-shaped rods connected to the bottom of the ring and connected to the pusher plate through the opening of the limiting channel. The extension rod can loosen and align the fibers while rotating. The four arc-shaped rods of the limiting block are evenly distributed in a circle, which can make the limiting block bear the force evenly.

[0009] As a further improvement of the present invention, the mold plate includes a push plate, a compression spring, a partition plate, a mold groove, a through-hole, and a mold shell. The partition plate and the mold shell are an integral structure. The compression spring is installed between the push plate and the partition plate. The mold groove and the mold shell are an integral structure. The through-hole is a slot between the partition plate and the mold shell. The inner wall of the mold groove is polished to reduce the adhesion between the rubber and the groove wall, which facilitates the demolding of the finished product.

[0010] As a further improvement of the present invention, the push plate moves under force, and the gas will run through the port to the other side to assist in drying. The push plate is made of a heat-conducting material and does not heat itself. The compression spring is stored in the groove of the partition plate under pressure. The push plate is made of a heat-conducting material, which can quickly conduct the heat of the mold shell and make the colloid in the mold groove heat evenly.

[0011] As a further improvement of the present invention, the pusher plate moves along the mold shell and prevents the colloid from flowing out. The mold shell is heated and temperature controlled on both the upper and lower sides. When the pusher plate is pressed down, the gas in the space will be squeezed out through the opening and the edge of the pusher plate. The heating temperature of the upper and lower sides of the mold shell can be adjusted independently to adapt to the vulcanization requirements of different types of rubber raw materials.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Firstly, it can precisely limit the cavity space of the colloid extruded into the mold plate. Through the uniform downward movement of the push plate driven by the colloid, combined with the limiting effect of the mold shell and the push plate, a closed and fixed-size molding space is formed. This avoids the colloid from flowing turbulently due to excessive reserved space, effectively suppresses the generation and residue of air bubbles, and ensures that the colloid is filled into the mold groove at a uniform speed, ensuring that the cavity is filled densely and improving the density uniformity and dimensional accuracy of the rubber ring after molding.

[0013] Secondly, as the colloid is extruded into the cavity, the push tube rotates with the rotating body and drives the extension rod to move inside. The extension rod loosens and combs the fibers inside the colloid by rotating and stirring, breaking the tendency of fiber agglomeration and promoting the uniform distribution of fibers in the colloid. This avoids the formation of local weak areas due to fiber agglomeration after vulcanization and molding, significantly improving the mechanical strength, sealing performance and overall structural stability of the rubber ring, and ensuring the consistency of the finished product performance.

[0014] Thirdly, the dual-station alternating operation design can effectively avoid the impact of temperature difference and moisture on the quality of the colloid. By controlling the shaft to drive the loading and unloading groups to rotate and switch stations, when the colloid is being processed at the upper station, the lower station that has already completed processing can simultaneously achieve natural heat dissipation. Combined with the airflow pretreatment generated by the push plate movement and extrusion, residual moisture on the inner wall of the mold cavity is efficiently removed. When switching to the upper operation, the mold cavity is already in a low moisture state, eliminating problems such as poor vulcanization and surface defects caused by the mixing of moisture and colloid from the source, and ensuring the stability of molding quality.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings: Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This invention provides an intelligent and rapid loading and unloading processing system for rubber sealing rings. Its structure includes a fixed frame 1, a support rod 2, a loading and unloading assembly 3, a nozzle 4, a control box 5, a support frame 6, a motor 7, and a moving rail 8. The fixed frame 1 is fixed to the support rod 2. The loading and unloading assembly 3 is supported and fixed by the support rod 2. The moving rail 8 is connected to the fixed frame 1. The support frame 6 is supported between the moving rail 8 and the control box 5. The control box 5 is connected to the nozzle 4 for control. The motor 7 controls the support frame 6 to move along the moving rail 8. The loading and unloading assembly 3 includes a control unit 31, a pusher pipe 32, a material bin 33, a rotating ring 34, a connecting frame 35, a control shaft 36, a connecting body 37, a fixed plate 38, a movable channel 39, a feed inlet 310, a conveying channel 311, a mold plate 312, a rotating body 313, movable wheels 314, and a transmission machine 315. The control unit 31 is connected to the rotating body 313 via gears. The conveying channel 311 connects the pusher pipe 32 and the material bin 33. The rotating ring 34 is connected to the fixed plate 38 and is rotatable. The control shaft 36... Installed between the connecting frame 35 and the connecting body 37, the movable wheel 314 is connected to the movable track 39 by a toothed connection, the transmission machine 315 is connected to the movable track 39, the feed port 310 is connected to the material bucket 33, the mold plate 312 is located between two fixed plates 38, and the connecting body 37 and the mold plate 312 are fastened together by bolts. It can withstand the radial load when the loading and unloading group 3 rotates, ensuring the stability of the structure. The dual-station design of the loading and unloading group 3 can pre-treat the water vapor generated by the other station when the single station is running.

[0024] The push tube 32 includes a limiting channel 21, a spring 22, a connecting ring 23, a connecting channel 24, an extension rod 25, a push plate 26, and a limiting block 27. The limiting channel 21 and the connecting channel 24 are integrated. The spring 22 is connected between the inner surface of the limiting channel 21 and the limiting block 27. The extension rod 25 and the push plate 26 are integrated. The limiting block 27 is connected to the push plate 26. The connecting ring 23 is fixed to the connecting channel 24. There are two push tubes 32, which are symmetrically distributed. The elastic restoring force of the spring 22 can drive the push plate 26 to automatically reset.

[0025] The nozzle 4 can be adjusted to the required angle, the loading and unloading assembly 3 can rotate 180 degrees, and the two workstations operate alternately. The support frame 6 moves and adjusts when the loading and unloading assembly 3 rotates to avoid obstructing the rotation path. The nozzle 4 can accurately spray the release agent as needed. The 180-degree rotation of the loading and unloading assembly 3 is driven by the control shaft 36 to ensure the accuracy of the docking between the two workstations.

[0026] The control shaft 36 controls the overall 180-degree rotation, the transmission 315 controls the movable wheel 314 to drive the fixed disk 38 to move along the movable channel 39, and the rotating body 313 drives the material bucket 33, the conveying channel 311, the pushing pipe 32 and the rotating ring 34 to rotate at a uniform speed. The rotating ring 34 can rotate along the fixed disk 38 while preventing the colloid from flowing out. The teeth of the movable wheel 314 and the movable channel 39 are tightly engaged, which can realize the smooth movement of the fixed disk 38 without jamming. The uniform rotation of the rotating body 313 can effectively prevent the rubber raw material in the mold plate 312 from delamination or fiber agglomeration.

[0027] The pusher plate 26, pushed by the colloid, will pull the limiting block 27 and the spring 22. The limiting block 27 moves through the opening of the limiting channel 21 and keeps the colloid from flowing out. The upper part of the limiting block 27 is a ring with four arc-shaped rods connected to the bottom of the ring and the opening of the limiting channel 21 to the pusher plate 26. The extension rod 25 can loosen and align the fibers while rotating. The four arc-shaped rods of the limiting block 27 are evenly distributed in a circle, which can make the limiting block 27 bear the force evenly. The movement trajectory of the extension rod 25 can loosen the accumulated fibers.

[0028] The specific usage and function of this embodiment are as follows: In this invention, the colloid is placed into the material tank 33 through the inlet 310. After the material tank 33 quantitatively controls the colloid, it is smoothly conveyed to the push tube 32 through the conveying channel 311. After the colloid enters the push tube 32, it generates a continuous pushing force that acts on the push plate 26, causing the limit block 27 to move synchronously and pulling the spring 22 to extend, so that the colloid is smoothly squeezed into the mold plate 312. During the colloid squeezing process, the control machine 31 synchronously drives the rotating body 313 to rotate, causing the material tank 33, the conveying channel 311, the push tube 32 and the rotating ring 34 to rotate synchronously along the fixed plate 38. The push plate 26 continuously moves downward towards the mold plate 312 to push the colloid. Its integrated extension rod 25 stirs the colloid in the mold plate 312 with the rotation, effectively loosening the fibers inside the colloid and preventing the fibers from agglomerating. After the colloid is delivered to ensure uniform distribution, the pusher plate 26 loses the extrusion force of the colloid. The spring 22 pulls the limit block 27 back to its original position by its own elastic restoring force, which drives the pusher plate 26 to return to its original position and seals the groove at the bottom of the rotating ring 34. Then the mold plate 312 starts the temperature control function to vulcanize the internal colloid. After the molding is completed, the transmission machine 315 drives the movable track 39 to mesh with the movable wheel 314, which drives the fixed plate 38 to move up and disengage from the mold plate 312. After the sealing ring loses its limit constraint, the extrusion spring 52 pushes the push plate 51 to push the finished product out. Finally, the motor 7 controls the support frame 6 to move along the moving rail 8 to the corresponding station. The control box 5 controls the nozzle 4 to blow air to demold the molded sealing ring. At the same time, the airflow further cools the finished product, completing a single processing cycle.

[0029] Example 2: As shown in the attached document Figure 6 To be continued Figure 7 As shown: The mold plate 312 includes a push plate 51, a compression spring 52, a spacer plate 53, a mold groove 54, a through-hole 55, and a mold shell 56. The spacer plate 53 and the mold shell 56 are an integral structure. The compression spring 52 is installed between the push plate 51 and the spacer plate 53. The mold groove 54 and the mold shell 56 are an integral structure. The through-hole 55 is a slot between the spacer plate 53 and the mold shell 56. The inner wall of the mold groove 54 is polished to reduce the adhesion between the rubber and the groove wall, which facilitates the demolding of the finished product. The spacer plate 53 can limit the push plate 51.

[0030] When the push plate 51 is moved under force, the gas will run through the opening 55 to the other side to assist in drying. The push plate 51 is made of thermally conductive material and does not heat itself. The compression spring 52 is stored in the groove of the partition plate 53 under pressure. The push plate 51 is made of thermally conductive material, which can quickly conduct the heat of the mold shell 56, so that the colloid in the mold groove 54 is heated evenly. The opening 55 can not only ensure the flow of gas, but also compress the space of the gas, so that the gas generates an impact force.

[0031] The pusher plate 51 moves along the mold shell 56 and prevents the colloid from flowing out. The mold shell 56 is heated and temperature controlled on both the upper and lower sides. When the pusher plate 51 is pressed down, the gas in the space will be squeezed out through the opening 55 and the edge of the pusher plate 51. The heating temperature of the upper and lower sides of the mold shell 56 can be adjusted independently to adapt to the vulcanization requirements of different types of rubber raw materials. The pusher plate 51 has a circular structure.

[0032] The specific usage and function of this embodiment are as follows: In this invention, after the vulcanization and molding of the rubber ring is completed, the control box 5 adjusts the nozzle 4 to blow air onto the finished sealing ring for demolding, and at the same time, the airflow is used to complete the cooling process. At this time, heating stops on one side of the mold plate 312, and a temperature difference is formed between its surface and the outdoor environment, which still makes it easy for water vapor to condense. Then, the control shaft 36 drives the loading and unloading assembly 3 to rotate as a whole through the connecting body 37, rotating the completed workstation to the bottom and the new workstation to be processed to the top, realizing dual-workstation operation to ensure processing continuity. When the push plate 26 of the new workstation is continuously pressed down by the pushing force of the colloid, it will simultaneously push the push plate 51 in the mold plate 312 to move along the mold shell 56, thereby squeezing the compression spring between the push plate 51 and the spacer plate 53. During the movement of the push plate 51, the gas in the mold groove 54 is compressed and flows through the port 55 to the mold groove 54 on the other side. It is continuously transported through the gap between the port 55 and the push plate 51 on the other side. This airflow can specifically remove the water vapor formed by the temperature difference and complete the pretreatment of the mold cavity in advance. The mold shell 56 only heats one side of the upper working position. When the upper working position is completed and rotated to the lower position, the push plate 51 at the lower end has naturally dissipated heat to close to room temperature. The residual water vapor is also removed by the airflow pretreatment. When the colloid is extruded later, the push plate 51 can simultaneously scrape off the trace amount of water vapor remaining on the inner wall of the mold shell 56 during the movement of the push plate 51 along the mold shell 56, thus avoiding the mixing of water vapor and colloid from the source and affecting the molding quality.
