Description

Technical Field

[0001] The present invention relates to the technical field of vulcanization treatment of sealing strips, and specifically to a sealing strip vulcanization treatment device and method. Background Art

[0002] Vulcanization is also known as crosslinking and curing. The process of adding crosslinking aids such as vulcanizing agents and accelerators to rubber and transforming linear macromolecules into a three-dimensional network structure under certain temperature and pressure conditions. Since sulfur was originally used to crosslink natural rubber, it is called vulcanization. When producing sealing rings, generally, sealing strips are cut, and then the cut sealing strips are connected end to end to form a sealing ring, and then the elasticity of the whole sealing ring and the connection strength of the connection position are further increased by vulcanization, so as to improve the quality of the sealing ring. The cutting and butt-joint work of the sealing strip is the preparatory work for the vulcanization treatment of the sealing ring.

[0003] The utility model patent with the application number CN202022533490.5 discloses a rubber sealing strip butt-fusion device, which relates to the technical field of sealing strips, and includes a support device, a lifting device, a welding device, a sliding device and a pressing device. The support device includes a support plate, a support table, a T-shaped block and a working plate. This device is not easy to shake during operation through the fixed base and the support rod, increasing the stability of the device. The first motor and the first lead screw torque transmission are facilitated through the driving turbine and the second limit block. The controller and the inductor facilitate the operator to control and adjust the machine. The hydraulic rod, the pressing plate and the second rod sleeve facilitate the pressing of the rubber sealing strip.

[0004] During the production and processing process, the production of sealing rings is also generally carried out in this way, that is, the sealing strips are cut, and the two ends of the cut sealing strips are connected end to end for bonding. This production method can only clamp and weld one sealing strip at a time, with cumbersome processing steps and low production efficiency. And when cutting, in order to facilitate butt-joint cutting, the cutting end face is vertically cut, resulting in a small contact area at the connection during butt-joint and poor connection strength of the fusion welding.

[0017] A usage method of a sealing strip vulcanization treatment device includes the following steps:

[0018] The first step: Install the first inner clamp seat and the second inner clamp seat in the installation groove through the second transverse fixing bolt. After passing the sealing strip through the material guiding cylinder, clamp the end of the sealing strip into the rear end fixing groove, and fix the end of the sealing strip through the rear end fixing groove to complete the preliminary installation work;

[0019] Step 2: Start the power motor to drive the winding roller to rotate. When the winding roller rotates, it drives the driving threaded shaft to rotate through the speed-changing transmission box. The driving threaded shaft drives the synchronous support seat and the material guiding cylinder to move through the thread. The material guiding cylinder drives the sealing strip to move horizontally to the right. At the same time, the winding roller rotates to wind the sealing strip on the surface of the winding roller, and through the material guiding cylinder, the sealing strip is spirally wound on the outside of the winding roller and will be stuck inside the rear guiding positioning groove;

The docking electric push rod pushes the first inner clamp seat, the first outer clamp seat and the upper extension clamp seat to move horizontally, shift and align the end of the cut sealing strip, so that the cut sealing strip forms a circle, and fix the misaligned upper extension clamp seat and the lower extension clamp seat through the longitudinal fixing bolt to keep the sealing strip in a circular state;

[0022] Step 5: Rotate the second horizontal fixing bolt to release the fixation between the second inner clamp seat and the mounting groove, and then the frame body composed of the first inner clamp seat, the second inner clamp seat, the first outer clamp seat and the second outer clamp seat can be removed for subsequent high-temperature welding work and vulcanization processing.

[0023] (III) Beneficial effects

[0024] The present invention provides a sealing strip vulcanization treatment device and method. It has the following beneficial effects:

[0025] 1. The sealing strip is spirally wound on the outside of the winding roller, and then the sealing strip is cut into equal-length strips at one time by the slitting device. The slitting work of multiple sealing strips can be completed at one time, improving the processing efficiency.

[0026] 2. By controlling the docking electric push rod to push the first inner clamp seat and the first outer clamp seat to move in a misaligned manner, the upper end of the cut sealing strip is moved, so that each independent cut sealing strip is connected end to end. Compared with the way of separate slitting and docking, the docking work of multiple cut sealing strips is carried out at one time, greatly improving the processing efficiency.

[0027] 3. When processing sealing rings of different lengths, by replacing the rear guiding positioning groove and the front fixing pressing groove molds with adapted pitches, the diameter of the processed sealing ring can be controlled. At the same time, by controlling the variable-speed transmission box to adjust the transmission gear ratio, the speed at which the driving threaded shaft rotates driven by the variable-speed transmission box when the winding roller rotates is adjusted, so that the speed at which the driving threaded shaft drives the synchronous support seat and the material guiding cylinder to move through the thread is adapted to the pitches of the replaced rear guiding positioning groove and the front fixing pressing groove.

[0028] 4. By replacing the adapted molds, sealing rings of different diameters and different thicknesses can be processed, with a wide range of applications. Without using sensors, the winding roller and the driving threaded shaft are driven by the same power source and transmitted by a variable-speed transmission box, resulting in high transmission stability.

[0029] 5. First, cut and align, and then perform welding and vulcanization processing. Compared with the method of first performing vulcanization processing and then cutting and welding, the strength of the welding position is improved. And the cutting position is an inclined plane, and the inclined cutting can increase the contact surface area during welding, further improving the connection strength.

[0041] Specifically, as shown in the attached Figures 2-7 figure, the wound sealing strip is fixed by the positioning device, and after slitting, the slitted sealing strip can be aligned at the end, so as to facilitate subsequent welding and vulcanization processing. And when the sealing strip is misaligned and aligned, the sealing strip changes from an inclined pulling state to a state where the end parts are aligned, so that the sealing strip becomes looser, reducing the friction between the sealing strip and the surface of the winding roller 2, and facilitating the subsequent removal of the sealing strip from the outside of the winding roller 2.

[0042] In this embodiment, the guiding device includes a positioning bracket 31, a driving threaded shaft 32, a speed-changing transmission box 33, a synchronous support base 34, and a material guiding cylinder 35. The positioning bracket 31 is installed on the top of the base 1. The driving threaded shaft 32 is rotatably installed on the right side wall of the positioning bracket 31 through a bearing. The speed-changing transmission box 33 for driving the transmission between the winding roller 2 and the driving threaded shaft 32 is installed on the right side wall of the support frame 11 and the right side wall of the positioning bracket 31. The synchronous support base 34 is sleeved outside the driving threaded shaft 32. A limiting chute is provided on the top of the base 1, and the bottom of the synchronous support base 34 is clamped inside the limiting chute. The material guiding cylinder 35 for guiding the rubber strip is installed on the top of the synchronous support base 34.

[0043] Specifically, as shown in the attached Figure 1 figure, when winding, the sealing strip is uniformly moved to the right along the outside of the winding roller 2 through the guiding device, so as to control the pitch of the spiral coil formed during winding, and enable the sealing strip to be stably clamped inside the rear guiding positioning groove 54.

[0044] In this embodiment, the slitting device includes a rear support frame 61, a cutting hydraulic column 62, a mounting clamp seat 63, and a thin cutting blade 64. The rear support frame 61 is installed at the rear side of the top of the base 1. The cutting hydraulic column 62 is installed on the top of the rear support frame 61. The mounting clamp seat 63 is installed at the bottom of the output end of the cutting hydraulic column 62. The thin cutting blade 64 for slitting is installed below the mounting clamp seat 63.

[0045] Specifically, as shown in the attached Figure 1 figure, the slitting device is arranged above the winding roller 2, and the thin cutting blade 64 is driven by the cutting hydraulic column 62 to move downward for slitting work.

[0046] In this embodiment, the inside of the speed-changing transmission box 33 is driven by gears, and a regulating electric telescopic rod for adjusting the transmission gear ratio is installed on the left side wall of the speed-changing transmission box 33.

[0047] Specifically, as shown in the attached Figure 1 figure, the stability of the transmission is improved through gear transmission, and the gear transmission ratio inside is adjusted by the electric telescopic rod on the left surface of the speed-changing transmission box 33. Its principle is merely using the gear transmission principle as a transmission component.

[0048] In this embodiment, the inner surface of the rear guiding positioning groove 54 is in the same arc surface as the outer wall of the winding roller 2.

[0049] Specifically, as shown in the attached Figure 2 figure, when the sealing strip is wound around the outer surface of the rear end fixing groove 52 and clamped inside the rear guiding positioning groove 54, the regularity of the spiral shape is maintained.

[0050] In this embodiment, there are several rear guiding positioning grooves 54 and front fixing pressing grooves 57, and the rear guiding positioning grooves 54 and the front fixing pressing grooves 57 are distributed in a spiral track as a whole.

[0051] Specifically, as shown in the attached Figure 5 and the attached Figure 7 figure, the sealing strip is wound inside the rear guiding positioning grooves 54 and the front fixing pressing grooves 57, so that the rubber strip can form a stable spiral shape, thereby improving the accuracy after subsequent cutting.

[0052] In this embodiment, the thickness of the thin cutting blade 64 is less than the thickness of the cutting knife groove 58.

[0053] Specifically, as shown in the attached Figure 1 and the attached Figure 5 and the attached Figure 7 figure, the thin cutting blade 64 is inserted into the cutting knife groove 58 to cut the sealing strip located inside the cutting knife groove 58. And the thickness of the thin cutting blade 64 is relatively thin. When cutting, the rubber strip will not be displaced under the combined clamping of the rear guiding positioning grooves 54 and the front fixing pressing grooves 57. When the thin cutting blade 64 is removed from the inside of the cutting knife groove 58, the rubber strip at the cut position will remain in contact.

[0054] In this embodiment, when the winding roller 2 rotates to drive the driving threaded shaft 32 to rotate through the variable speed transmission box 33, the distance that the driving threaded shaft 32 drives the synchronous support seat 34 to move through the thread is equal to the pitch of the rear guiding positioning grooves 54 and the front fixing pressing grooves 57.

[0055] Specifically, as shown in the attached Figure 1 and the attached Figure 5 figure, when the rubber strip is wound on the surface of the winding roller 2 under the restriction of the material guiding cylinder 35, it can be stably clamped into the rear guiding positioning grooves 54.

[0056] A method for using a sealing strip vulcanization treatment device includes the following steps:

[0057] The first step: Install the first inner clamping seat 43 and the second inner clamping seat 44 in the installation groove 41 through the second transverse fixing bolt 51. After passing the sealing strip through the material guiding cylinder 35, clamp the end of the sealing strip into the rear end fixing groove 52, and fix the end of the sealing strip through the rear end fixing groove 52 to complete the preliminary installation work;

[0058] Step 2: Start the power motor 21 to drive the winding roller 2 to rotate. When the winding roller 2 rotates, it drives the driving threaded shaft 32 to rotate through the speed-changing transmission box 33. The driving threaded shaft 32 drives the synchronous support seat 34 and the material guiding cylinder 35 to move through the thread, drives the sealing strip to move horizontally to the right through the material guiding cylinder 35. At the same time, the winding roller 2 rotates to wind the sealing strip on the surface of the winding roller 2, and through the material guiding cylinder 35, the sealing strip is spirally wound on the outside of the winding roller 2 and will be stuck inside the rear guiding positioning groove 54.

[0059] Step 3: After winding is completed, remove the second horizontal fixing bolt 51, clamp the first outer clamp seat 45 and the second outer clamp seat 46 on the outside of the sealing strip through the front fixing groove 57, and then fix the first outer clamp seat 45 and the second outer clamp seat 46 through the first horizontal fixing bolt 50 and the second horizontal fixing bolt 51.

[0060] Step 4: Control the winding roller 2 to drive the cutting knife groove 58 to point to the position directly above, control the cutting hydraulic column 62 to drive the mounting clamp seat 63 and the thin cutting blade 64 to move downward, cut the sealing strip by inserting the thin cutting blade 64 into the cutting knife groove 58, remove the longitudinal fixing bolt 49, and then control the docking electric push rod 59 to extend. The docking electric push rod 59 pushes the first inner clamp seat 43, the first outer clamp seat 45 and the upper extension card seat 47 to move horizontally, shift and align the end of the cut sealing strip, so that the cut sealing strip forms a circle. Fix the misaligned upper extension card seat 47 and the lower extension card seat 48 through the longitudinal fixing bolt 49 to keep the sealing strip in a circular state.

[0061] Step 5: Rotate the second horizontal fixing bolt 51 to release the fixation between the second inner clamp seat 44 and the mounting groove 41, and then the frame body composed of the first inner clamp seat 43, the second inner clamp seat 44, the first outer clamp seat 45 and the second outer clamp seat 46 can be removed for subsequent high-temperature welding work and vulcanization processing.

[0062] Working principle and usage process of the present invention: The first inner clamping seat 43 and the second inner clamping seat 44 are installed inside the installation groove 41 through the second horizontal fixing bolt 51. After passing the sealing strip through the material guiding cylinder 35, the end of the sealing strip is clamped into the rear end fixing groove 52. The end of the sealing strip is fixed through the rear end fixing groove 52 to complete the preliminary installation work. Then, control the power motor 21 to start. The power motor 21 drives the winding roller 2 to rotate. When the winding roller 2 rotates, the driving threaded shaft 32 is driven to rotate by the gears inside the speed change transmission box 33. When the driving threaded shaft 32 rotates, the thread drives the synchronous support seat 34 and the material guiding cylinder 35 to move. The material guiding cylinder 35 drives the sealing strip to move horizontally to the right. At the same time, the winding roller 2 rotates to wind the sealing strip on the surface of the winding roller 2. And through the material guiding cylinder 35, the sealing strip is spirally wound on the outside of the winding roller 2 and will be stuck inside the rear guiding positioning groove 54. After the winding is completed, control the winding roller 2 to drive the cutting knife groove 58 to rotate to the position at the top and then stop rotating. Then rotate the second horizontal fixing bolt 51 to remove the second horizontal fixing bolt 51. The first outer clamping seat 45 and the second outer clamping seat 46 are clamped outside the sealing strip through the front fixing groove 57. At this time, the sealing strip is clamped inside the front fixing groove 57. The sealing strip is positioned through the cooperation of the rear guiding positioning groove 54 and the front fixing groove 57. Then control the cutting hydraulic cylinder 62 to drive the installation clamping seat 63 and the thin cutting blade 64 to move downward. The thin cutting blade 64 extends into the cutting knife groove 58 to cut the sealing strip. Remove the longitudinal fixing bolt 49. Then control the docking electric push rod 59 to extend. The docking electric push rod 59 pushes the first inner clamping seat 43, the first outer clamping seat 45 and the upper extension clamping seat 47 to move horizontally. The end of the cut sealing strip is shifted and aligned. The moving distance is the length of the pitch of the spiral formed during winding, so that the cut sealing strip forms a circle. The upper extension clamping seat 47 and the lower extension clamping seat 48 after dislocation are fixed through the longitudinal fixing bolt 49 to keep the sealing strip in a circular state. Rotate the second horizontal fixing bolt 51 to release the fixation between the second inner clamping seat 44 and the installation groove 41. Control the support regulating telescopic rod 12 to drive the sliding support 13 to move to the right, so that there is a gap between the sliding support 13 and the winding roller 2 for the sealing strip to move out of the outside of the winding roller 2. Then the frame body composed of the first inner clamping seat 43, the second inner clamping seat 44, the first outer clamping seat 45 and the second outer clamping seat 46 can be removed for subsequent high-temperature welding work and vulcanization processing. And the contact section is oval, increasing the contact area and improving the connection strength. First cut and then vulcanize, further improving the strength of the welding position.

[0063] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
