Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tire patch production, in particular to an integrated production and processing technology for an American tire tire patch. Background Art
[0002] A tire patch is a small patch used to repair a tire, usually made of rubber or synthetic materials. The working principle of a tire patch is mainly to use the adhesive force between the film and the damaged part of the tire to seal the damaged part and prevent gas leakage. During the repair process, it is usually necessary to release the air inside the tire, find the damaged point, then clean the impurities and oil stains on the damaged part, then stick the tire patch on the damaged part, and finally inflate the tire to make the tire patch fit tightly on the tire. The tire patch is embedded with cords, which are used to enhance the strength and durability of the tire patch after production.
[0003] The production and processing technology of tire patch mainly includes the steps of raw material preparation, mixing, calendering, vulcanization, cutting and packaging. In the cord embedding stage of existing tire patch production and processing, a layer of adhesive is usually applied on a rubber sheet first, and then the cords are arranged and laid on the adhesive. After the cords are laid, another rubber sheet is covered, and finally the formed sheet is calendered as a whole to be compacted.
[0004] In the cord embedding process of the existing tire patch production, the cord itself has thickness. When the cord is arranged on the glue on the sheet, the bottom of the cord contacts the glue, but the top is difficult to contact the glue. This makes it difficult for the new sheet to adhere to the glue when it is covered on the cord, and finally the adhesion between the cord and the new sheet is not strong, and even a large range of cavities exists. In addition, this production method of first applying the adhesive will cause the sheet coated with a large area of adhesive to be exposed to the air. Impurities in the air are easy to adhere to the adhesive and mix into the whole sheet, which not only reduces the overall strength of the sheet after adhesion, but also makes the thickness of the tire patch produced uneven, resulting in a decrease in the quality of the tire patch produced. Moreover, simply using the calendering method to press the two sheets together will make the sheet have a large internal stress. After calendering, the overall shape of the sheet will change slightly, which makes the whole sheet easy to be misaligned. To this end, we propose an integrated molding production and processing technology for American tire patch. Summary of the invention
[0005] The purpose of the present invention is to provide an integrated production and processing technology for an American tire tire patch, which can effectively solve the problems raised in the background technology.

The linear speed of the positioning shaft is the same as the conveying speed of the conveyor.
[0008] Preferably, the glue coating assembly includes a glue coating roller, a rotating plate, a second motor, and a glue adding assembly. The glue coating roller and the rotating plate are movably arranged in the middle of two mounting seats, and there is a gap between the glue coating roller and the rotating plate for accommodating the adhesive. In step four, the glue adding assembly is first used to evenly add adhesive to the gap between the glue coating roller and the rotating plate, and the conveyor conveys the sheet with the cord to the glue coating assembly, and then the second motor is used to drive the glue coating roller to rotate, and the linear speed of the glue coating roller is greater than the moving speed of the sheet. Then, the rotating plate is adjusted to rotate so that a gap appears between the bottom of the rotating plate and the glue coating roller. During the glue coating process, the glue coating roller brings the adhesive out of the gap, and the glue coating roller applies the adhesive to the surface of the sheet to cover the cord on the surface of the sheet.
[0009] Preferably, the glue adding component includes a slide assembly fixedly installed above the calender and a glue nozzle fixedly arranged on a slide seat in the slide assembly; in step four, the slide assembly is used to adjust the glue nozzle to move back and forth in the gap between the glue coating roller and the rotating plate to evenly add adhesive into the gap.

[0012] Preferably, in step 4, a conveyor is used to continue conveying the compacted sheet as a whole to the pressing rollers of a calender, and the height of the sheet as a whole on the surface of the conveyor is the same as the height in the pressing rollers of the calender.
[0013] Preferably, the tidying component includes a rotating roller movably arranged at the discharge end of the calender, a conveyor belt wound around the outside of the two rotating rollers, a plurality of support plates arranged on the outer side of the conveyor belt, and a support seat arranged inside the calender, and a fourth motor for driving the rotating roller to rotate is arranged on the outside of the calender, and the support plate is made of a flexible material and has a triangular prism structure; in step four, the sheet output from the pressing roller of the calender as a whole enters between the conveyor belts in the two tidying components, and the support plate on the outer side of the conveyor belt supports the sheet as a whole.
[0014] Preferably, in step 4, the conveying speed of the conveyor belt is greater than the moving speed of the entire sheet.
[0015] The present invention has the following beneficial effects: 1. The present invention uses a feeding assembly to convey one of the sheets, arranges the cords in parallel on the sheet, and then uses a glue coating assembly to evenly apply adhesive on the sheet with the cords. The adhesive can adhere the cords to the surface of the sheet, so that the cords will not be misplaced during the subsequent conveying of the sheet.
[0016] 2. The present invention uses a clamping assembly to lay another sheet on top of the sheet coated with adhesive, and presses the two sheets together, so that the adhesive between the two sheets can be squeezed evenly, avoiding the problem of uneven thickness of the tire patch produced due to uneven distribution of the adhesive between the two sheets. By conveying the compressed sheet as a whole to the calender for compaction, the air between the two sheets can be discharged, so that the two sheets are more tightly bonded, and the cords are more closely combined between the two sheets.
[0017] 3. The present invention, by conveying the compacted sheet as a whole to two regular components for state maintenance, and conveying the two layers of sheet into two regular components for state maintenance after calendering, can prevent the two sheets from deforming and misaligning due to excessive change in external pressure causing internal stress to be released too quickly when the external pressure is suddenly removed after calendering. Regular components are used to shape the sheet as a whole, maintain the two sheets and the cords in a compressed state, increase the compression time of the sheet as a whole, and allow the adhesive to stably bond the sheet as a whole.
[0018] 4. The present invention can adjust the thickness of the glue on the surface of the glue roller by adjusting the gap size between the bottom of the rotating plate and the glue roller, thereby adjusting the thickness of the adhesive on the sheet. The linear speed of the glue roller is greater than the sheet conveying speed, so that the adhesive attached to the surface of the glue roller is in a pulling state on the cord when it contacts the cord, and because the positioning shaft presses the cord, the cord without adhesive attached will not be pulled by the adhesive on the surface of the glue roller, so that the cord without adhesive attached will not be separated from the sheet, and the cord attached with adhesive is adhered to the surface of the sheet by the adhesive, so it will not be pulled by the adhesive on the surface of the glue roller, so that the position of the cord will not shift during the adhesive coating process. The linear speed of the glue roller is greater than the sheet conveying speed, so that the surface of the glue roller can pass over the cord, so that the adhesive at different places on the surface of the glue roller is adhered to the cord, ensuring that the adhesive on the cord is fully coated, and avoiding the situation where the adhesive is insufficiently coated at the contact point between the cord and the sheet.
[0019] 5. The present invention adopts a production method of placing the cord, applying the glue, pressing the sheet, rolling the whole sheet, and finally performing the whole sheet state, so that the exposed surface of the adhesive is small, it is not easy to mix with impurities, the adhesion is strong, and the tire repair sheet produced is stronger. In addition, this production method can timely empty the air inside the stacked sheets, solving the problem of unclean air discharge in the production process of first bonding and then compacting to remove the air inside the sheets. The two sheets are bonded tightly, closely and neatly, and it is not easy for air to exist at the cord, it is not easy to be hollow, and the cord is not easy to be misplaced. There will be no problem of excessive local accumulation of adhesive due to uneven distribution of adhesive, and inconsistent thickness of the tire repair sheet produced.
[0020] 6. The present invention uses a support plate to support the entire sheet material, thereby avoiding contact between the conveyor belt and the entire sheet material, avoiding adhesive or impurities adhering to the conveyor belt that may cause excessive local pressure on the entire sheet material, causing changes in the position of glue or cords inside the entire sheet material, and avoiding uneven distribution of adhesive inside the entire sheet material that may cause changes in the overall thickness of the sheet material. While conveying the entire sheet material, the present invention can also reduce the clamping force on the entire sheet material, avoiding excessive stress in the upper and lower sheets, and preventing the entire sheet material from being significantly deformed after being discharged from the regular assembly, thereby achieving a better shaping effect on the entire sheet material.
[0021] 7. The present invention makes the conveying speed of the conveyor belt greater than the moving speed of the entire sheet. While the support plate is used to pull the entire sheet, it avoids prolonged contact between the support plate and the entire local part of the sheet, and avoids the support plate from pressing the entire local part of the sheet for a long time, which causes the corresponding internal position of the entire local position of the sheet to be subjected to excessive force for a long time, causing the adhesive to be squeezed out, resulting in insufficient adhesion of the entire sheet and uneven thickness of the entire sheet.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0026] See also Figure 1 - Figure 7 As shown, a one-piece production and processing technology for an American tire tire patch includes the following steps: Step 1: Weigh the required raw materials according to the formula ratio, and put the raw materials into an internal mixer for high-temperature mixing; Step 2: putting the rubber material after internal mixing into an open mixer for further mixing to reach the desired plastic state; Step 3, feeding the plastic rubber material into a calendering assembly to calender into a sheet of target thickness; Step 4: Use a stacking assembly to add adhesive and cords between two sheets of the same shape and size, and compact the two sheets; the adhesive is used to enhance the bonding between the two sheets and the cords, and the cords are used to enhance the strength and durability of the finished tire patch, which can effectively resist the air pressure inside the tire and the external impact force, ensuring that the tire patch can be firmly fixed in the repaired tire and is durable.
[0027] The stacking assembly includes a calender 1, a feeding assembly 4, a gluing assembly 5, a clamping assembly 6, and two regularization assemblies 7; first, the feeding assembly 4 is used to convey one of the sheets, and the cords are evenly laid on the sheet, and then the gluing assembly 5 is used to evenly apply adhesive on the sheet with the cords, and then the clamping assembly 6 is used to lay another sheet on the sheet coated with adhesive, and the two sheets are pressed together, and the pressed sheets are conveyed as a whole to the calender 1 for compaction, and finally the compacted sheets are conveyed as a whole to the two regularization assemblies 7 for state maintenance; Step 5: cutting the compacted sheet into preformed sheets of target size; Step 6: Put the preformed sheet into the vulcanizer for vulcanization. Vulcanization is carried out at a certain temperature and pressure to cross-link the rubber molecules and form a stable three-dimensional network structure. The vulcanization time and cooling time should be appropriate to ensure complete vulcanization and proper cooling of the tire patch.
[0028] Step 7: Cut and trim the vulcanized and cooled preformed sheet to obtain the desired final tire patch, and then package the tire patch.
[0029] Based on this design, during the mixing, calendering and vulcanization process, the temperature is strictly controlled to avoid excessively high or low temperatures affecting product quality. During the production process, the equipment and environment must be kept clean to avoid impurities from mixing into the rubber compound.
[0030] Based on this process, by first using the feeding component 4 to convey one of the sheets, arranging the cords parallel to the sheet, and then using the glue coating component 5 to evenly apply adhesive on the sheet with the cords, the cords can be adhered to the surface of the sheet through the adhesive, so that the cords will not be misplaced during the subsequent conveying of the sheet.
[0031] By using the clamping assembly 6 to lay another sheet on top of the sheet coated with adhesive, the two sheets are pressed together, so that the adhesive between the two sheets can be squeezed evenly, avoiding the problem of uneven thickness of the tire patch produced due to uneven distribution of adhesive between the two sheets. By conveying the compressed sheet as a whole to the calender 1 for compaction, the air between the two sheets can be discharged, so that the two sheets are more tightly bonded, and the cords are more closely combined between the two sheets.
[0032] By conveying the compacted sheet as a whole to two regularization components 7 for maintaining its state, and conveying the two layers of sheet material into two regularization components 7 for maintaining their state after calendering, it can be prevented that when the external pressure on the two sheets is suddenly removed after calendering, the external pressure changes too quickly, causing the internal stress to be released too quickly, resulting in the two sheets being deformed and misaligned. The regularization component 7 is used to shape the sheet as a whole, maintain the two sheets and the cords in a compressed state, increase the compression time of the sheet as a whole, and allow the adhesive to stably bond the sheet as a whole.
[0033] This process adopts a production method that places the cord, applies glue, presses the sheet, calenders the sheet as a whole, and finally performs the production of the sheet as a whole. This makes the exposed surface of the adhesive small, and it is not easy to mix impurities, so that the adhesion is strong, and the tire patch produced has higher strength. In addition, this production method can timely evacuate the air inside the stacked sheets, solving the problem of unclean air discharge in the production process of first bonding and then compacting the air inside the sheets. The two sheets are bonded tightly, closely and neatly, and it is not easy for air to exist at the cord, it is not easy to be hollow, and the cord is not easy to be misplaced. There will be no problem of uneven distribution of adhesive causing excessive local accumulation of adhesive, and inconsistent thickness of the tire patch produced.
[0034] Among them, the feed end of the calender 1 is fixedly provided with two mounting seats 2. In step four, the feeding assembly 4 includes a conveyor 41 fixedly provided at the feed end of the calender 1, a positioning shaft 42 movably provided between the two mounting seats 2, and a first motor 43 fixedly provided on the side of the calender 1 and used to drive the positioning shaft 42 to rotate. The positioning shaft 42 is located above the feeding end of the conveyor 41. A plurality of annular grooves 3 are provided on the circumference of the positioning shaft 42, and the cords are placed inside the annular grooves 3. A sheet of material is placed on the feeding end of the conveyor 41, and the sheet is covered with evenly spaced cords, and the cords and the annular grooves 3 correspond one to one. The positioning shaft 42 presses the cords on the surface of the sheet, and the first motor 43 drives the positioning shaft 42 to rotate. The linear speed of the positioning shaft 42 is the same as the conveying speed of the conveyor 41.
[0035] Based on this design, the conveyor 41 and the positioning shaft 42 keep the sheet in a constant speed conveying state, the cord is in the annular groove 3, and the positioning shaft 42 presses the cord on the surface of the sheet. As the positioning shaft 42 rotates, the cord is evenly distributed on the surface of the sheet. In the subsequent gluing stage of the glue coating roller 51, the positioning shaft 42 presses the cord during the rotation of the glue coating roller 51, so that the glue coating roller 51 with adhesive will not stick to the cord, thereby avoiding the situation where the cord is adhered and causes the cord position to shift.
[0036] Among them, the glue coating component 5 includes a glue coating roller 51, a rotating plate 52, a second motor 53, and a glue adding component 54. The glue coating roller 51 and the rotating plate 52 are movably arranged in the middle of the two mounting seats 2, and there is a gap between the glue coating roller 51 and the rotating plate 52 for accommodating the adhesive; in step four, firstly, the glue adding component 54 is used to evenly add adhesive to the gap between the glue coating roller 51 and the rotating plate 52, and the conveyor 41 conveys the sheet with the cord to the glue coating component 5, and then the second motor 53 is used to drive the glue coating roller 51 to rotate, and the linear speed of the glue coating roller 51 is greater than the moving speed of the sheet, and then the rotating plate 52 is adjusted to rotate, so that a gap appears between the bottom of the rotating plate 52 and the glue coating roller 51, and the glue coating roller 51 brings the adhesive out of the gap during the process, and the glue coating roller 51 applies the adhesive to the surface of the sheet to cover the cord on the surface of the sheet.
[0037] Based on this design, by adjusting the gap between the bottom of the rotating plate 52 and the glue roller 51, the thickness of the glue on the surface of the glue roller 51 can be adjusted, so that the thickness of the adhesive on the sheet can be adjusted. The linear speed of the glue roller 51 is greater than the sheet conveying speed, so that the adhesive attached to the surface of the glue roller 51 is in a pulling state on the cord when it contacts the cord, and because the positioning shaft 42 presses the cord, the cord without adhesive attached will not be pulled by the adhesive on the surface of the glue roller 51, so that the cord without adhesive attached will not be separated from the sheet, and the cord attached with adhesive is adhered to the surface of the sheet by the adhesive, so it will not be pulled by the adhesive on the surface of the glue roller 51, so that the position of the cord will not be offset during the adhesive coating process. The linear speed of the glue roller 51 is greater than the sheet conveying speed, so that the surface of the glue roller 51 can pass over the cord, thereby squeezing the adhesive at different places on the surface of the glue roller 51 onto the cord, ensuring that the adhesive on the cord is fully coated, and avoiding the situation where the adhesive is insufficiently coated at the contact point between the cord and the sheet.
[0038] Among them, the glue adding component 54 includes a slide assembly 541 fixedly installed above the calender 1, and a glue outlet nozzle 542 fixedly arranged on a slide seat in the slide assembly 541; in step four, the slide assembly 541 is used to adjust the glue outlet nozzle 542 to move back and forth in the gap between the glue coating roller 51 and the rotating plate 52, and the adhesive is evenly added to the gap.
[0039] Based on this design, the adhesive is evenly injected into the gap between the glue coating roller 51 and the rotating plate 52 .
[0040] Among them, a power component for driving the rotating plate 52 to rotate is arranged inside one of the mounting seats 2. The power component adjusts the gap size between the bottom of the rotating plate 52 and the glue coating roller 51 to adjust the glue thickness on the surface of the glue coating roller 51. The rotating plate 52 is an arc-shaped plate structure.
[0041] Based on this design, it is convenient to adjust the gap size between the bottom of the rotating plate 52 and the glue roller 51, so as to adjust the glue thickness on the surface of the glue roller 51. The rotating plate 52 is an arc plate structure, so that the gap between the rotating plate 52 and the glue roller 51 can accommodate more adhesive.
[0042] Among them, the clamping assembly 6 includes a clamping roller 61 and a guide roller 62 movably arranged between two mounting seats 2, and a third motor 63 fixedly arranged on the outside of the calender 1. The third motor 63 drives the guide roller 62 to rotate, and the linear speed of the guide roller 62 is the same as the conveying speed of the conveyor 41; in step four, another sheet is fed between the guide roller 62 and the clamping roller 61, and the clamping roller 61 presses the sheet above the sheet coated with adhesive, and the two sheets are pressed together, and the adhesive and the cord are clamped between the two sheets.
[0043] Based on the present design, the guide roller 62 facilitates the change of the deflection direction of the sheet during transport, and the clamping roller 61 is used to press a new sheet onto the sheet coated with adhesive.
[0044] In step 4, the compacted sheet is continuously conveyed to the pressing roller of the calender 1 by using the conveyor 41 , and the height of the sheet on the surface of the conveyor 41 is the same as the height in the pressing roller of the calender 1 .
[0045] Based on this design, the entire sheet is in a horizontal state during transportation and will not bend, thereby preventing the internal adhesive and cord from changing position due to bending of the two sheets.
[0046] Among them, the regularization component 7 includes a rotating roller 71 movably arranged at the discharge end of the calender 1, a conveyor belt 72 wound around the outside of the two rotating rollers 71, a plurality of support plates 73 arranged on the outer side of the conveyor belt 72, and a support seat 74 arranged inside the calender 1. The outer side of the calender 1 is provided with a fourth motor 8 for driving the rotating roller 71 to rotate. The support plate 73 is made of a flexible material and has a triangular prism structure. In step 4, the sheet material output from the rollers of the calender 1 enters between the two conveyor belts 72 in the regularization component 7 as a whole, and the support plate 73 on the outer side of the conveyor belt 72 supports the sheet material as a whole. The conveyor belt 72 slides on the surface of the support seat 74, and the support seat 74 supports the conveyor belt 72, so that during the conveying process of the sheet material as a whole on the support plate 73, the support force of the support plate 73 on the sheet material as a whole is relatively consistent.
[0047] Based on the present design, a support plate 73 is used to support the entire sheet material to avoid contact between the conveyor belt 72 and the entire sheet material, to avoid adhesive or impurities adhering to the conveyor belt 72 causing excessive local pressure on the entire sheet material, causing changes in the position of the glue or cord inside the entire sheet material, and to avoid uneven distribution of adhesive inside the entire sheet material causing changes in the overall thickness of the sheet material. While conveying the entire sheet material, the clamping force on the entire sheet material can also be reduced to avoid excessive stress in the upper and lower sheets. After the entire sheet material is discharged from the regularization component 7, the entire sheet material will not be significantly deformed, and the overall shaping effect on the sheet material is better.
[0048] Among them, in step 4, the conveying speed of the conveyor belt 72 is greater than the moving speed of the entire sheet.
[0049] Based on this design, while the support plate 73 is used to pull the entire sheet, prolonged contact between the support plate 73 and the entire local portion of the sheet is avoided, and prolonged compression of the entire local portion of the sheet by the support plate 73 is avoided, which may cause the corresponding internal position of the entire local position of the sheet to be subjected to excessive force for a long time, causing the adhesive to be squeezed out, resulting in insufficient bonding of the entire sheet and uneven thickness of the entire sheet.
