Description

Technical Field

[0001] The invention relates to the technical field of insole processing, and more specifically to a four-layer film-wrapped gas forming machine for shoemaking and a production process thereof. Background Art

[0002] The air insoles in our daily life are generally single-layer air insoles. In daily use, single-layer air insoles are relatively simple in structure and consist of only a layer of film. Therefore, they are prone to breakage when worn or impacted by external forces, causing damage to the air insoles, which in turn affects their use effect and lifespan.

[0003] In order to enhance the wear resistance and durability of the insole, an additional layer of film is generally adhered to the surface of the insole to make a double-layer insole. This double-layer structure can improve the wear resistance of the insole. Even if the outer film is damaged or damaged by foreign objects during use, as long as the inner air cushion remains intact, the normal use function of the air insole can still be guaranteed. However, in actual application, this double-layer insole also has some problems. Since the bonding strength of the glue is affected by many factors, such as ambient temperature, humidity changes, and usage time, the double-layer insole is prone to degumming during use. Degumming not only affects the appearance of the insole, but also has a serious impact on its performance, such as reducing the comfort, support and stability of the insole. In severe cases, the insole will be damaged. In severe cases, degumming may even cause the insole to be unusable. This is because in the production process of existing air insoles, a tubular film sleeve is generally extruded through an extruder, and the tubular film sleeve is conveyed to a pre-designed mold, and the mold is pressed. Subsequently, the blow molding machine blows a certain amount of hot gas into the mold through a specific device. Under the action of the gas pressure, the film material will gradually expand and fit tightly to the inner wall shape of the mold, thereby forming an air insole. Because the existing extruder can generally only extrude a single tubular film sleeve, and cannot extrude a double tubular film sleeve, this makes it impossible for the existing air insole production process to be processed into a double-layer air insole. It can be seen that the existing equipment for processing air insoles has certain limitations.

[0004] In addition, the existing air insole processing equipment has some other shortcomings. For example, it is impossible to conduct a comprehensive quality inspection on the processed air insoles. Specifically, it is impossible to accurately determine whether the processed air insoles have air leakage problems. Air leakage is a common quality problem of air insoles. It will cause the insoles to lose their proper cushioning and support effects, seriously affecting the user's comfort and sports performance. These equipment cannot accurately measure and evaluate the hardness of the air insoles. Hardness is one of the important indicators for evaluating the performance of air insoles. It is directly related to the comfort and adaptability of the insoles. If the hardness of the processed air insoles does not meet the design requirements or industry standards, then these insoles will hardly meet the needs of consumers. Summary of the invention

[0082] The control assembly includes a support frame 8, which is arranged at the right end of the control box 1; a first cylinder 9, which is installed on the support frame 8; a connecting block 10, which is installed at the output end of the first cylinder 9; a moving seat 11, which is designed in a U-shape, and the moving seat 11 is fixedly connected to the upper end of the connecting block 10, and a male template 13 and a female template 14 are arranged in the moving seat 11; a second cylinder 12, which is divided into two groups, and the two groups of second cylinders 12 are respectively fixedly installed on the left and right inner walls of the moving seat 11, and the output ends of the two groups of second cylinders 12 are respectively fixedly connected to the corresponding male template 13 and female template 14;

[0083] A cutter 36 , the cutter 36 is arranged at the lower end of the extruder 2 , and the cutter 36 is arranged at a position close to the discharge die 3 ; a frame 35 , the frame 35 is installed at the left end of the cutter 36 ; a fifth cylinder 34 , the output end of the fifth cylinder 34 is connected to the left end of the frame 35 , and the fifth cylinder 34 is installed on the extruder 2 .

[0084] By adopting the above technical scheme, when making air insoles, first, the flowing film material is squeezed into the discharge die 3 through the extruder 2, and the film material enters the film discharge cavity 5 through the feed port 4, and will first come to the outer film of the film separation cylinder 6, and then enter the interior of the film separation cylinder 6 through the feed hole 7, and finally be discharged from the lower end of the film discharge cavity 5, so as to achieve the effect of discharging two films at one time. As the extruded film moves downward, it will finally come between the male template 13 and the female template 14. When the extruded film comes to the appropriate position between the male template 13 and the female template 14, the second cylinder 12 is controlled to extend, so that the male template 13 and the female template 14 are close to each other, and finally they are combined to realize the mold closing operation. At this time, the fifth cylinder 3 4 extends out, pushing the frame 35 and the cutting knife 36 to move forward, the cutting knife 36 will cut the film connected above the male template 13 and the female template 14, and cut off the connected film, and then control the fifth cylinder 34 to retract in preparation for the next cutting operation. After the cutting is completed, the first cylinder 9 will extend and push the connecting block 10 to move. The connecting block 10 is fixedly connected to the moving seat 11, so the moving seat 11 will move synchronously with the connecting block 10. Because the male template 13 and the female template 14 are installed on the moving seat 11, the moving seat 11 will also drive the male template 13 and the female template 14 to move when it moves. Finally, the male template 13 and the female template 14 after the mold is closed are moved to the bottom of the blowing assembly to perform the blowing operation.

[0085] In some embodiments of the present invention, the blowing assembly includes an air inlet groove 15, which is provided at the upper ends of the male template 13 and the female template 14; a connecting groove 16, which is provided on the male template 13, the connecting groove 16 is provided below the air inlet groove 15, and the connecting groove 16 and the air inlet groove 15 are interconnected; a sealing block 17, which is arranged in the connecting groove 16, and one end of the sealing block 17 passes through the male template 13 and extends to the outside; a third cylinder 18, the output end of the third cylinder 18 is connected to the end of the sealing block 17 away from the connecting groove 16, and the third cylinder 18 is away from the sealing block 1 7 is mounted on the movable seat 11; an air injection pipe 28, which is arranged at the rear end of the discharge die 3; a support plate 29, which is mounted on the upper end of the air injection pipe 28; a fourth cylinder 30, the output end of the fourth cylinder 30 is fixedly connected to the support plate 29; a support rod 33, which is mounted on the upper end of the control box 1, and the fourth cylinder 30 is mounted on the support rod 33; an air pump 32, which is mounted on the upper end of the control box 1; an air guide pipe 31, one end of the air guide pipe 31 is connected to the exhaust port of the air pump 32, and the end of the air guide pipe 31 away from the air pump 32 is connected to the air injection pipe 28;

[0086] The first clamping plate 19, the first clamping plate 19 is fixedly connected to the rear end of the female template 14; the demarcation groove 22, the demarcation groove 22 is opened on the first clamping plate 19; the second clamping plate 20, the second clamping plate 20 is fixedly connected to the rear end of the male template 13; the demarcation knife 21, the demarcation knife 21 is installed on the side surface of the second clamping plate 20, the demarcation knife 21 will be inserted into the demarcation groove 22 when the male template 13 and the female template 14 are closed, and the demarcation knife 21 will be disengaged from the demarcation groove 22 when the male template 13 and the female template 14 are opened.

[0087] By adopting the above technical solution, after the first cylinder 9 stops moving, the air intake groove 15 will stay directly below the air injection pipe 28, and then the blowing operation will be performed to control the fourth cylinder 30 to extend, and the fourth cylinder 30 will push the support plate 29 to move downward, and the air injection pipe 28 will also move downward. Finally, the air injection pipe 28 will be inserted into the air intake groove 15. At this time, the air pump 32 performs an air supply operation to input air into the air guide pipe 31, and finally the air will enter the air intake groove 15 through the air injection pipe 28. It should be noted that in the prior art, an air heating device is generally installed in the air delivery path of the air guide pipe 31 to heat the air to form hot air. Because this technology is a prior art, the present invention is not shown in the figure, and the detailed description of heating the air is not made here. The air guide pipe 31 of the present invention is made of flexible material. The air in the air inlet groove 15 will enter the connecting groove 16, and finally enter the extruded film to perform the blowing operation. The film expands and finally fits the inner wall of the male template 13 and the female template 14. At this time, the third cylinder 18 extends to push the sealing block 17 to move. Finally, the sealing block 17 will fill the connecting groove 16 and squeeze the film in the connecting groove 16. Because the temperature of the film is hot at this time, it has good thermoplasticity. After the sealing block 17 is squeezed, the multi-layer film will be bonded together to achieve the air inlet channel of the sealed insole to prevent the air in the insole from escaping through the air inlet channel when the mold is opened. After the multi-layer film is bonded, the third cylinder 18 retracts to the initial position, and the second cylinder 12 also retracts to the initial position, and pulls the male template 13 and the female template 14 to separate, and finally realizes the mold separation. After the mold separation is completed, the first cylinder 9 also retracts to the initial position at the same time, and the mold closing operation is performed again. When the air injection tube 28 is injecting air, the film will wrap the outside of the air injection tube 28. After demolding, because the film has been cooled and shaped, and because there is friction between the shaped film and the outer wall of the air injection tube 28, the processed insole can be prevented from falling off. When the male template 13 and the female template 14 are molded again, the first clamping plate 19 and the second clamping plate 20 will be driven synchronously, and finally the deburring knife 21 will enter the deburring groove 22 to cut the edge of the air insole to remove the excess film at the edge of the air insole, so that the insole is separated from the excess film at the edge. At this time, the fourth cylinder 30 is retracted and controls the air injection tube 28 to move upward. Because the first clamping plate 19 and the second clamping plate 20 clamp the excess film at the edge of the insole, the excess film at the edge will not move upward with the air injection tube 28.When the male template 13 and the female template 14 move to the bottom of the air injection assembly after the mold is closed, the first splint 19 and the second splint 20 will also be pushed to move to the rear end and leave the bottom of the air injection assembly. After the air injection assembly is finished working, the male template 13 and the female template 14 are separated when the mold is opened, and the first splint 19 and the second splint 20 are also separated. The previously cut insole and excess film on the edge will fall off from the first splint 19 and the second splint 20. In this way, it is achieved that the operation of automatically cutting the excess film on the edge of the insole can be realized when processing the insole.

[0088] In some embodiments of the present invention, the detection assembly includes a telescopic block 24, which is movably embedded in the first clamping plate 19, one end of the telescopic block 24 extends outside the first clamping plate 19, and the end of the telescopic block 24 located inside the first clamping plate 19 is fixedly connected to the pressure sensor 25, the temperature sensor 23 is installed on the first clamping plate 19, and the temperature sensor 23 and the telescopic block 24 are installed on the same side of the first clamping plate 19; a mounting plate 26, which is installed on the end of the pressure sensor 25 away from the telescopic block 24; a spring 27, which is installed on the end of the mounting plate 26 away from the pressure sensor 25, and the end of the spring 27 away from the mounting plate 26 is fixedly connected to the first clamping plate 19;

[0089] The detection assembly also includes a storage unit for storing the values ​​detected by the corresponding pressure sensor 25 when the first clamping plate 19 and the second clamping plate 20 clamp the air insole at different temperatures. ;

[0090] The processing unit is used to obtain the current temperature of the air insole through the temperature sensor 23, and based on the current temperature, obtain the value that the pressure sensor 25 should detect at the current temperature of the air insole through the storage unit. ; Obtain the actual detected pressure value through the pressure sensor 25 , and calculate to get ,like , indicating that the tested air insole is qualified; if , it means that the tested air insole is unqualified.

[0091] By adopting the above technical solution, when the mold is closed, the first clamping plate 19 and the second clamping plate 20 will clamp the air insole, the temperature sensor 23 will be close to the surface of the air insole, and collect the temperature of the surface of the air insole. When the first clamping plate 19 and the second clamping plate 20 are clamped, the telescopic block 24 will be squeezed by the air insole, and the telescopic block 24 will enter the interior of the first clamping plate 19, while driving the pressure sensor 25 and the mounting plate 26 to move together, the mounting plate 26 will squeeze the spring 27, and the pressure sensor 25 will detect the squeezing force of the air insole on the telescopic block 24. In this way, a qualified air insole is used in advance, the air insole is clamped at different temperatures, and the values ​​obtained by the pressure sensor 25 at different temperatures of the air insole are obtained, and then the different temperatures and corresponding values ​​are stored in the storage unit.

[0092] If the air sole is less inflated or leaking, the air sole is softer, and the deformation of the part of the air sole that acts on the telescopic block 24 is larger under the same squeezing force. In this case, the value detected by the actual pressure sensor 25 is smaller than the value detected under a qualified air insole. If the air sole is more inflated, the air insole is harder, and the deformation of the part of the air sole that acts on the telescopic block 24 is smaller under the same squeezing force. In this case, the value detected by the actual pressure sensor 25 is larger than the value detected under a qualified air insole. Because the material of the air insole has different hardness at different temperatures, and the expansion coefficient of air at different temperatures is different, when testing the sole, the temperature data of the insole is first obtained, and then the pressure that a qualified insole should measure at this temperature is obtained. , the actual pressure With pressure For comparison, if , indicating that the actual measured pressure is lower than the specified pressure, indicating that the air insole tested is too soft, indicating that it is insufficiently inflated or the insole is leaking; if , indicating that the actual measured pressure is greater than the specified pressure, indicating that the tested air insole is too hard, which means that the tested air insole is unqualified. In this way, different unqualified insoles can be screened out, and qualified air soles can be selected at the same time.

[0093] In some embodiments of the present invention, based on the stored pressure value and the actual measured pressure value Calculate the gas delivery volume that needs to be adjusted by the air pump 32. The specific calculation formula is: ,in Expressed as weight coefficient, It represents the gas delivery volume that the air pump 32 needs to adjust.

[0094] By adopting the above technical solution, a soft insole indicates insufficient inflation during inflation, and a hard insole indicates excessive inflation during inflation. The result is a positive number, which means the insole is too soft and the air volume needs to be increased. The result is a negative number, which means the insole is too hard and the air volume needs to be reduced. The positive or negative result tells us whether to adjust the air pump 32 to increase or decrease the air supply. The calculation formula is: , The larger the difference is, the larger the air supply needs to be adjusted. By setting the weight coefficient and multiplying the difference by the weight coefficient, the air supply that needs to be adjusted by the air pump 32 can be obtained. By adjusting the air supply of the air pump 32, it can be ensured as much as possible that the next group of air insoles processed meet the standards, thereby improving the product qualification rate.

[0095] In some embodiments of the present invention, the detection component further includes when detecting the previous set of air soles, and the calculated After the air pump 32 adjusts the air delivery volume, if the current air insole is detected, it is calculated , it means that the previous set of air insoles processed has leakage.

[0096] By adopting the above technical solution, if the insole leaks, the hardness of the insole measured again increases significantly after the air supply of the air pump 32 is increased. Here, the range in which the insole hardness can be increased after the air supply is increased can be set. If the test result is significantly greater than the range in which the insole hardness increases, it means that the insoles of the previous group tested are caused by leakage, not by insufficient air supply, that is, the air pump 32 is adjusted to increase the original air supply, and at the same time, it is determined that the previous group of air soles are leaking.

After the connected film is cut, the first cylinder 9 pushes the male mold plate 13 and the female mold plate 14 after closing the mold to move to the bottom of the blowing assembly to perform the blowing operation;

[0100] Step 3, the fourth air cylinder 30 controls the air injection pipe 28 to be inserted into the air inlet groove 15, and the air pump 32 operates to blow air into the male template 13 and the female template 14;

[0101] Step 4, after the mold closing operation again, the first clamping plate 19 and the second clamping plate 20 will clamp the air insole formed by the previous set, and the edge removal knife 21 will enter the edge removal groove 22 to cut the edge film of the air insole;

[0102] Step 5, when the edge film of the air insole is cut off, the detection component detects whether the processed air insole is qualified through the temperature sensor 23 and the pressure sensor 25.
