Description

Technical Field

[0001] The invention relates to the field of pressure equipment, in particular to a heat-insulating cotton insole and a production and finishing process thereof. Background Art

[0002] In the process of insole production, square sheets are usually used for heat pressing and cutting. The square sheets are made of multiple layers of rubber or polymer materials stacked and bonded together. They are then heated and pressurized by hot pressing and shaping equipment to form a concave and convex shape that fits the foot structure. Finally, they are sent to the cutting process to cut out the required shape of the insole to obtain the insole.

[0003] Since rubber sheets have high surface friction and are soft in texture, they are difficult to separate automatically due to adsorption or adhesion after being stacked. The use of traditional automated equipment is prone to problems such as material jamming and multiple sheets sticking together. Therefore, manual loading and unloading operations are usually performed in the prior art.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Examples, such as Figure 1-Figure 9 As shown: The present invention provides a thermal insulation cotton insole and a production and finishing process thereof, wherein the thermal insulation cotton insole is prepared by finishing a sheet material A to obtain a sheet material A in the shape of an insole, and the sheet material A in the shape of an insole is cut to obtain an insole body B; The sheet material A used is composed of a plurality of layered materials, including cloth, thermal insulation cotton, foam and aluminum foil. The two sides of the sheet material A are cloth and aluminum foil respectively. The sheet material A having the shape of an insole after finishing has no change in material. The thermal insulation cotton insole of this embodiment is obtained by cutting a sheet A in the shape of an insole along the contour of the insole, including an insole body B, in which the thickness of the foam accounts for 40%-60% of the total thickness; the cloth is terry cloth, the foam is Conbo foam, and the thermal insulation cotton can be made of rubber and plastic thermal insulation cotton, polyurethane foam, plush cotton, etc. according to the needs of technical personnel in this field. It is known that the cutting equipment can be a pressure cutting machine with a cutting knife mold, or manual trimming can be performed, which will not be elaborated here.

[0029] The production and finishing process of the thermal insulation cotton insole of this embodiment adopts a hot press body 1 to finish the sheet A so that the sheet A is formed into the shape of an insole. The hot press body 1 includes a pressing head 12 and a workbench 11. The pressing head 12 is provided with an upper mold and the workbench 11 is provided with a lower mold 13. At a certain temperature, the pressing head 12 drives the upper mold to squeeze the sheet A on the lower mold 13, so that the insole is heated and shaped into the shape of an insole. A cloth mechanism 3 is provided around the lower mold 13 and a feeding mechanism 2 and a unloading mechanism 4 are respectively provided on both sides of the workbench 11, thereby including three parts: a feeding mechanism 2, a cloth mechanism 3, and an unloading mechanism 4.

[0030] As for the feeding mechanism 2, the feeding mechanism 2 includes a material rack 21 for placing the sheet A and a discharging assembly for driving a single sheet A to be separately discharged from the stacked sheet A. In this embodiment, the single sheet A driven by the feeding mechanism 2 is separately discharged from the bottom of the stacked sheet A, so that when the sheet A is placed from the top of the material rack 21, the discharge of the sheet A below will not be interrupted, and the sheet A can be moved to the discharging assembly below by its own weight; To this end, a base 22 is provided below the material rack 21 and a discharging assembly of the loading mechanism 2 is mounted on the base 22. The discharging assembly includes a middle rack 24 located in the middle of the base 22 and a side rack 26 on the side of the base 22. The middle rack 24 and the side rack 26 form at least three supporting positions for the sheet A at the front, middle and rear sides. When the material is not discharged, the middle rack 24 and the side rack 26 support the sheet A above. The top of the middle rack 24 and the side rack 26 are both provided with contact wheels 23 for contacting the sheet A. The middle rack 24 and the side rack 26 drive the contact wheels 23 at the top to support the sheet A in the material rack 21. The side frame 26 is swingably mounted on the base 22, and a cylinder-type second push-pull actuator 27 is connected between the side frame 26 and the base 22 to drive the side frame 26 to swing. The swing axis of the side frame 26 is perpendicular to the movement direction of the fabric mechanism 3, so that the swing of the side frame 26 is outwardly expanded and inwardly clamped. It should be noted that the length of the side frame 26 is greater than the length of the sheet A. Moreover, the sliding seat 31 of the middle frame 24 is installed on the base 22, and a first cylinder-type push-pull actuator 25 is connected between the middle frame 24 and the base 22 to drive the middle frame 24 to slide. The sliding direction of the middle frame 24 is parallel to the movement direction of the cloth mechanism 3. In this embodiment, the middle frame 24 is divided into two at the bottom end of the sheet A and forms two supporting parts in the middle of the sheet A. The first push-pull actuator 25 drives the two middle frames 24 to move closer to or away from each other, so as to adjust the support position and support range of the sheet A. In addition, the discharging assembly also includes a guide assembly 28 for guiding the side frame 26 to rise so as to lift the penultimate layer and the sheet A above it. The guide assembly 28 includes a base plate 281, and an inclined rise groove 281a is provided on the base plate 281. Side rotating shafts 26a are provided on both sides of the side frame 26 and are nested in the inclined rise groove 281a. A first return spring 283 is provided between the side rotating shaft 26a and the top of the inclined rise groove 281a to drive the side rotating shafts 26a on both sides of the side frame 26 to stabilize at the bottom of the inclined rise groove 281a. A person skilled in the art may optionally embed a bearing 282 on the side rotating shaft 26a to make the movement of the rotating shaft in the inclined rise groove 281a smoother, and a top seat 284 is also provided between the bearing 282 and the first return spring 283 to prevent the first return spring 283 from being offset due to force. In addition, the discharging assembly also includes a guide lifting frame 29, which is installed on the base 22. The front end surface of the guide lifting frame 29 is inclined and is used to contact the side frame 26. The distance between the top end of the front end surface of the guide lifting frame 29 and the middle frame 24 is smaller than the distance between the bottom end and the middle frame 24, thereby determining the inclination direction of the front end surface of the guide lifting frame 29. It should be noted that the inclination amplitude of the inclined lifting groove 281a is the same as the inclination amplitude of the front end surface of the guide lifting frame 29, and the angle between the side frame 26 resting on the guide lifting frame 29 and the second push-pull actuator 27 is greater than 90°, so that the force applied by the second push-pull actuator 27 and the combined force of the side frame 26 on the guide lifting frame 29 will not be reversely offset; Therefore, the discharging assembly conveys sheet A separately through three steps: First, the second push-pull actuator 27 drives the side frame 26 to swing outward of the sheet A so that the edge of the sheet A loses the support of the side frame 26 and droops. At the same time, the first push-pull actuator 25 drives the two middle frames 24 to move closer to each other, controlling the distance that the sheet A extends from the middle frame 24. The extension distance increases, thereby increasing the drooping amplitude of the sheet A. Then, the second push-pull actuator 27 drives the side frame 26 to swing toward the inner side of the sheet A, so that the top end of the side frame 26 is inserted between the sheet A of the first to last layer and the sheet A of the second to last layer, and the contact wheel 23 on the side frame 26 enters between the sheet A of the first to last layer and the sheet A of the second to last layer, and the sheet A passes through the side frame 26; Finally, the second push-pull actuator 27 continues to drive, and the side frame 26 is pushed against the guide frame 29 and slides up on the guide frame 29, so that the penultimate layer and the sheet A above are lifted up, and the sheet A of the penultimate layer and the sheet A of the penultimate layer that are in contact with each other are separated, thereby avoiding the sheets A from contacting and rubbing against each other. At this time, the fabric assembly can be used to remove the sheet A of the penultimate layer, that is, the sheet A located between the side frame 26 and the middle frame 24.

[0031] It should be noted that, those skilled in the art know that whether the sagging amplitude of the sheet A is in place can be obtained through actual testing to obtain a stable sagging amplitude and position range, or can be detected by a sensor to determine the working range, stop position and time node of the first push-pull actuator 25.

[0032] As for the material dispensing mechanism 3, the material dispensing mechanism 3 is movably mounted on the workbench 11 through the moving assembly 5. The material dispensing mechanism 3 includes a clamping mechanism that moves on the moving assembly 5 and is used to drive the sheet A of the feeding mechanism 2 to move to the lower mold 13. Specifically, the moving assembly 5 includes a guide rail 51 mounted on the workbench 11 and a slider 53 slidably mounted on the guide rail 51, as well as a transmission belt 52 for driving the slider 53 to move and a motor for driving the transmission belt 52 to operate. The cross frame 32 of the material dispensing mechanism 3 is mounted on the slider 53 so as to move on the workbench 11, and the clamping mechanism includes a clamping mechanism that moves on the moving assembly 5 and is used to drive the sheet A of the feeding mechanism 2 to move to the lower mold 13. Specifically, the moving assembly 5 includes a guide rail 51 mounted on the workbench 11 and a slider 53 slidably mounted on the guide rail 51, as well as a transmission belt 52 for driving the slider 53 to move and a motor for driving the transmission belt 52 to operate. The claw cylinder 33, also known as the finger cylinder, has a pair of claws at the front end of the cylinder, and the claws are driven to expand or clamp by the cylinder. Correspondingly, a limit block 13b is provided on the side of the lower mold 13 away from the feeding mechanism 2 to limit the position of the sheet A brought by the clamping mechanism. A clearance groove 13a is provided on the side of the limit block 13b to make way for the clamping mechanism so that the clamping mechanism can move the sheet A to the top surface of the lower mold 13, and a guide seat 6 is provided on the workbench 11 to drive the horizontal height of the cross frame 32 to drop so that the clamping mechanism drives the sheet A to drop to the top surface of the lower mold 13 for placement; To this end, the cross frame 32 is connected to the slider 53 through the sliding seat 31, and a vertical guide rail 321 is provided on the sliding seat 31. The cross frame 32 and the guide rail 321 are nested and connected, and a second return spring 322 is provided between the cross frame 32 and the sliding seat 31; a driven wheel 31a is provided on the side of the cross frame 32, and an inclined guide groove 6a is provided on the guide seat 6, and the opening of the guide groove 6a at one end close to the feeding mechanism 2 is located on the moving path of the driven wheel 31a, and the guide groove 6a is close to the feeding mechanism 2. The horizontal height of one end is higher than the horizontal height of the end of the guide groove 6a away from the feeding mechanism 2. Therefore, when the clamping mechanism on the horizontal frame 32 drives the sheet A to move to the lower mold 13, the driven wheel 31a enters the guide groove 6a. As the horizontal frame 32 continues to move, the driven wheel 31a is affected by the guide groove 6a and descends along the guide groove 6a, causing the horizontal height of the horizontal frame 32 to drop. Then the clamping cylinder 33 is deployed at the make way groove 13a, so that the sheet A is placed on the lower mold 13.

[0033] It should be noted that the sheet A clamped by the clamping claw cylinder 33 will sag, so that the aluminum film of the sheet A can be located at the bottom for stacking, so that when the bottom surface of the sheet A sags and contacts the lower mold 13, there will not be too much friction; However, in this embodiment, in addition to this, an auxiliary support mechanism 34 is also provided on the horizontal frame 32 of the cloth mechanism 3, which is used to support the bottom of the sheet A when the clamping mechanism drives the sheet A to move. The auxiliary support mechanism 34 includes a movable seat 343 and a horizontal support rod 341 movably installed in the movable seat 343. A rotary actuator 342 is provided on the horizontal frame 32 to drive the horizontal support rod 341 to perform telescopic movement; Specifically, the auxiliary support mechanism 34 also includes a chain mounting seat 344 and a chain 345 installed in the chain mounting seat 344, the chain 345 is connected to the cross brace rod 341, and a driving sprocket 346 is also provided in the chain mounting seat 344. The rotary actuator 342 is connected to the driving sprocket 346 to drive the chain 345 to move, and the chain 345 includes a plurality of chain links 3451 hingedly connected to each other, and a mutual limiting section 3452 is provided on one side of the chain link 3451, and the mutual limiting section 3452 is in the form of a sheet and the flat sheet structure The surface is parallel to the hinge swing axis of the chain link 3451, and the length of the mutual limiting section 3452 is equal to the spacing between the hinge connection points at both ends of a single chain link 3451, so that the chain links 3451 of the chain 345 extended by the driven sprocket 346 are offset against each other through the mutual limiting section 3452, so that the chain 345 is extended in a straight shape, thereby driving the cross support rod 341 to extend to support the bottom of the sheet A, and the use of the chain 345 can drive the cross support rod 341 to extend and retract with a large stroke in a short time, making the movement faster.

[0034] As for the unloading mechanism 4, the unloading mechanism 4 is installed through the moving component 5, including the clamping cylinder 33 and the mounting frame connecting the clamping cylinder 33 with the slider 53. The slider 53 drives the clamping cylinder 33 to extend into the hot press body 1 to clamp the sheet A on the lower mold 13 and drive it, so that the feeding mechanism 3 can continue to feed the material. It can be known that the clamping cylinder 33 of the unloading mechanism 4 on the lower mold 13 is also provided with a make way groove 13a.

[0035] The production and finishing process of the thermal insulation cotton insole of this embodiment is carried out by the following steps: S1, prepare sheet A, and stack several sheets A and place them on the feeding mechanism 2; S1-1, the second push-pull actuator 27 drives the side frame 26 to swing outward of the sheet A so that the edge of the sheet A loses the support of the side frame 26 and droops. At the same time, the first push-pull actuator 25 drives the two middle frames 24 to move closer to each other, controlling the distance that the sheet A extends from the middle frame 24. The extension distance increases, thereby increasing the drooping amplitude of the sheet A. S1-2, the second push-pull actuator 27 drives the side frame 26 to swing toward the inner side of the sheet A, so that the top end of the side frame 26 is inserted between the sheet A of the first to last layer and the sheet A of the second to last layer, and the contact wheel 23 on the side frame 26 enters between the sheet A of the first to last layer and the sheet A of the second to last layer, and the sheet A passes through the side frame 26; S1-3, the second push-pull actuator 27 continues to drive, the side frame 26 is pressed against the guide frame 29 and slides upward on the guide frame 29, so that the penultimate layer and the upper sheet A are lifted up, and the penultimate layer of sheet A and the penultimate layer of sheet A that are attached to each other are separated; S2, feeding and distributing materials. The feeding mechanism 2 is ready to output a single sheet A from the stacked sheets A. The distributing mechanism 3 drives the single sheet A output by the feeding mechanism 2 to move onto the lower mold 13 of the hot press body 1; S2-1, when the clamping mechanism clamps the sheet A and pulls it out, the auxiliary support mechanism 34 works to drive the cross support rod 341 to extend, and the support length of the cross support rod 341 for the sheet A is not less than half of the width of the sheet A; S2-2, the auxiliary support mechanism 34 gradually drives the cross support rod 341 to retract during the process of the clamping mechanism descending, until the sheet A is placed on the lower mold 13; S3, hot pressing finishing, the pressure head 12 of the hot press machine body 1 descends to drive the upper mold to press the sheet A of the lower mold 13, and the sheet A is formed into a shape that conforms to the insole body B under the hot pressing of the upper mold and the lower mold 13; S4, the material is cooled. After the hot pressing and finishing step is completed, the pressure head 12 drives the upper mold to rise, and the material unloading mechanism 4 takes the sheet A on the lower mold 13 away from the lower mold 13 for subsequent cutting; The trimmed sheet A is subsequently cut according to the contour of the insole on the sheet A by a pressure cutting device, thereby obtaining the insole body B.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
