Description

Technical Field

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

[0002] Vulcanization is also called cross-linking or aging. It is a process of adding cross-linking agents such as vulcanizers and accelerators to rubber to transform linear macromolecules into three-dimensional network structures under certain temperature and pressure conditions. Since sulfur was first used to achieve cross-linking of natural rubber, it is called vulcanization. When producing sealing rings, sealing strips are generally cut, and then the cut sealing strips are connected end to end to form a sealing ring, and then vulcanization is used to further increase the overall elasticity of the sealing ring and the connection strength of the connection position, thereby improving the quality of the sealing ring. The cutting and docking of sealing strips is used as a preliminary preparation for the vulcanization treatment of the sealing ring.

[0003] The utility model patent with application number CN202022533490.5 discloses a rubber sealing strip butt fusion device, which relates to the field of sealing strip technology, including a supporting device, a lifting device, a welding device, a sliding device and a clamping device, and the supporting device includes a supporting plate, a supporting platform, a T-block and a working plate. The device fixes the base and the support rod to prevent the device from shaking during operation, thereby increasing the stability of the device. The active turbine and the second limit block facilitate the transmission of torque between the first motor and the first screw rod. The controller and the sensor facilitate the operator to control and adjust the machine. The hydraulic rod, the clamping plate and the second rod sleeve facilitate the compression of the rubber sealing strip.

[0004] During the production process, the production of sealing rings is also generally carried out in this way, that is, the sealing strip is cut, and the two ends of the sealing strip are connected end to end and bonded after cutting. This production method can clamp and weld one sealing strip at a time. The processing steps are cumbersome and the production efficiency is low. In addition, when cutting, the end face is cut vertically for the convenience of docking, resulting in a smaller contact area during docking and poor welding connection strength.

[0016] (III) Beneficial effects The present invention provides a sealing strip vulcanization treatment device and method, which has the following beneficial effects: 1. Wrap the sealing strip in a spiral shape on the outside of the winding roller, and then cut the sealing strip into strips of equal length at one time through the slitting device. The slitting work of multiple sealing strips can be completed at one time, which improves the processing efficiency.

[0017] 2. By controlling the docking electric push rod to push the first inner clamp seat and the first outer clamp seat to move in an offset manner, the upper end of the cut sealing strip is moved, so that each independent cut sealing strip is connected to the end. Compared with the separate cutting and docking method, multiple cut sealing strips are docked at one time, which greatly improves the processing efficiency.

[0018] 3. When processing sealing rings of different lengths, the diameter of the processed sealing ring can be controlled by replacing the rear guide positioning groove and the front fixed pressing groove mold with matching pitch. At the same time, the transmission gear ratio is adjusted by controlling the speed transmission box to adjust the speed of the driving threaded shaft driven by the speed transmission box when the winding roller rotates, so that the speed of the driving threaded shaft driving the synchronous support seat and the guide barrel to move through the thread when the driving threaded shaft rotates is compatible with the pitch of the replaced rear guide positioning groove and the front fixed pressing groove.

The winding roller and the driving threaded shaft are driven by the same power source and a variable speed transmission box, which has high transmission stability.

[0020] 5. The method of cutting and aligning first and then welding and vulcanization is adopted. Compared with the method of first vulcanization and then cutting and welding, the strength of the welding position is improved, and the cutting position is a beveled surface. The bevel can increase the contact surface area during welding, further improving the strength of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Specifically, as attached Figure 2-7 As shown, the wound sealing strip is fixed by the positioning device, and the tail of the cut sealing strip can be aligned after slitting, so as to facilitate the subsequent welding and vulcanization processing, and when the sealing strip is offset and aligned, the sealing strip changes from a slanted state to a state of alignment of the tail ends, 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.

[0026] In this embodiment, the guiding device includes a positioning bracket 31, a driving threaded shaft 32, a speed transmission box 33, a synchronous support seat 34 and a material guide cylinder 35. The positioning bracket 31 is installed on the top of the base 1, and the driving threaded shaft 32 is rotatably installed with the right side wall of the positioning bracket 31 through a bearing. The speed transmission box 33 for transmitting 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 seat 34 is sleeved on the outside of the driving threaded shaft 32. A limiting slide groove is provided on the top of the base 1, and the bottom of the synchronous support seat 34 is clamped in the limiting slide groove. The material guide cylinder 35 for guiding the rubber strip is installed on the top of the synchronous support seat 34.

[0027] Specifically, as attached Figure 1 As shown, the sealing strip is moved rightward at a uniform speed along the outer side of the winding roller 2 by the guiding device during winding, thereby controlling the pitch of the spiral coil formed during winding, so that the sealing strip can be stably clamped inside the rear guide positioning groove 54.

[0028] In this embodiment, the slitting device includes a rear support frame 61, a cutting hydraulic column 62, a mounting clamp 63 and a thin cutting blade 64.

[0029] Specifically, as attached Figure 1 As shown, the slitting device is arranged above the winding roller 2, and the thin cutting blade 64 is driven downward by the cutting hydraulic cylinder 62 to perform the slitting work.

[0030] In this embodiment, the speed change transmission box 33 is driven by gears, and a control electric telescopic rod for adjusting the transmission gear ratio is installed on the left side wall of the speed change transmission box 33.

[0031] Specifically, as attached Figure 1 As shown, the transmission stability is improved by gear transmission, and the internal gear transmission ratio is adjusted by the electric telescopic rod on the left surface of the speed change transmission box 33. The principle is simply to use the gear transmission principle as a transmission component.

[0032] In this embodiment, the inner surface of the rear guide positioning groove 54 and the outer wall of the winding roller 2 are located in the same arc surface.

[0033] Specifically, as attached Figure 2 As shown, when the sealing strip is wound around the outer surface of the rear end fixing groove 52 and is stuck inside the rear guide positioning groove 54, the regularity of the spiral shape is maintained.

[0035] Specifically, as attached Figure 5 and attached Figure 7 As shown, the sealing strip is wound around the rear guide positioning groove 54 and the front fixed pressing groove 57, so that the rubber strip can form a stable spiral shape, thereby improving the accuracy of subsequent cutting.

[0036] In this embodiment, the thickness of the thin cutting blade 64 is smaller than the thickness of the cutting groove 58 .

[0037] Specifically, as attached Figure 1 , Attachment Figure 5 and attached Figure 7 As shown, the thin cutting blade 64 is inserted into the cutting groove 58 to cut the sealing strip inside the cutting 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 cooperation and clamping of the rear guide positioning groove 54 and the front fixed pressing groove 57.

[0038] In this embodiment, when the winding roller 2 rotates and drives the driving threaded shaft 32 to rotate through the speed change transmission box 33, the driving threaded shaft 32 drives the synchronous support seat 34 to move a distance equal to the pitch of the rear guide positioning groove 54 and the front fixed pressure groove 57 through the thread.

When the winding roller 2 rotates, the driving threaded shaft 32 is driven to rotate through the speed transmission box 33. The driving threaded shaft 32 drives the synchronous support seat 34 and the guide cylinder 35 to move through the thread. The guide 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 around the surface of the winding roller 2. The sealing strip is spirally wound around the outer side of the winding roller 2 through the guide cylinder 35 and is stuck in the rear guide positioning groove 54. Step 3: After winding is completed, remove the second transverse fixing bolt 51, clamp the first outer clamp seat 45 and the second outer clamp seat 46 on the outer side 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 transverse fixing bolt 50 and the second transverse fixing bolt 51; Step 4: Control the winding roller 2 to drive the cutting knife groove 58 to point to the position just above, control the cutting hydraulic column 62 to drive the installation clamp seat 63 and the thin cutting blade 64 to move downward, and extend the thin cutting blade 64 into the cutting knife groove 58 to cut the sealing strip, remove the longitudinal fixing bolt 49, and then control the docking electric push rod 59 to extend, and the docking electric push rod 59 pushes the first inner clamp seat 43, the first outer clamp seat 45 and the upper extension clamp seat 47 to offset laterally, and the ends of the cut sealing strip are shifted and aligned, so that the cut sealing strip forms a circle, and the displaced upper extension clamp seat 47 and the lower extension clamp seat 48 are fixed by the longitudinal fixing bolt 49 to keep the sealing strip in a circular state; Step 5: Turn the second transverse fixing bolt 51 to release the fixation between the second inner clamp seat 44 and the mounting groove 41, and then the frame consisting 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 and vulcanization processing.

[0041] The working principle and use process of the present invention are as follows: the first inner clamp seat 43 and the second inner clamp seat 44 are installed in the installation groove 41 by the second transverse fixing bolt 51, and after the sealing strip passes through the guide barrel 35, the end of the sealing strip is inserted into the rear end fixing groove 52, and the end of the sealing strip is fixed by the rear end fixing groove 52. After completing the preliminary installation work, the power motor 21 is controlled to start, and the power motor 21 drives the winding roller 2 to rotate. When the winding roller 2 rotates, the gear inside the speed change transmission box 33 drives the driving threaded shaft 32 to rotate. When the driving threaded shaft 32 rotates, the thread drives the synchronous support seat 34 and the guide barrel 35 to move, and the guide barrel 35 is driven by the thread. The material barrel 35 drives the sealing strip to move horizontally to the right, and at the same time, the winding roller 2 rotates to wind the sealing strip on the surface of the winding roller 2, and the sealing strip is spirally wound around the outside of the winding roller 2 through the guide barrel 35, and is stuck in the inside of the rear guide positioning groove 54.

At this time, the sealing strip is stuck on the inner side of the front fixed pressure groove 57, and the rear guide positioning groove 54 and the front fixed pressure groove 57 are matched.

The extended clamping seat 48 is fixed to keep the sealing strip in a circular state, and the second transverse fixing bolt 51 is turned to release the fixation between the second inner clamping seat 44 and the mounting groove 41, and the control support and regulation telescopic rod 12 drives the sliding support 13 to move to the right, so that a gap is retained 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, and then the frame 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 and vulcanization processing, and the contact section is elliptical, which increases the contact area and improves the connection strength. Cutting first and then vulcanization further improves the strength of the welding position.
