Description

Technical Field

[0001] The invention relates to the technical field of film processing, in particular to a multi-material TPU film processing device for a breast patch. Background Art

[0002] Nipple covers are a kind of sticky object used on the nipple of the human chest to cover the areola, so as to achieve the effect of invisible underwear. It is the best way to replace bras. Nipple covers are made of high-grade silicone. The color and feel are close to human skin. They are directly adhered to the chest when used. They are natural and comfortable and integrated with the chest. Common shapes of nipple covers include heart-shaped, flower-shaped, U-shaped, round and apple-shaped, etc. Of course, there are many colors, such as red, skin color, black, yellow and white, etc. No matter what color or shape the nipple cover is, its surface must be equipped with TPU film during production.

[0003] In the existing technology, such as a multi-material breast patch TPU film processing device in Chinese patent application CN112606066A, it includes a support table, the upper surface of the support table is fixedly connected to a base, the inner wall of the base is fixedly connected to a top seat, the bottom of the base is fixedly connected to a collecting table, the inner wall of the base is provided with a processing mechanism, the inner wall of the base is fixedly connected to a support plate, and the inner wall of the base is rotatably connected to three transfer rollers. The multi-material TPU film processing device for breast implants can achieve the purpose of synchronously winding and cutting the TPU film through the processing mechanism, avoiding the problem of winding and die-cutting becoming two separate processes which increases the workload of the staff, thereby saving time and effort for the staff. The cut films can be collected uniformly through the collection table so that the staff can collect them, thereby improving work efficiency and greatly increasing the production speed. Although this patent can achieve simultaneous winding and film cutting, when the film cutter rises and moves back after cutting the TPU film, the rising and moving film may cause the cut circular TPU film to move upward and fall on the TPU film that has just been cut and is being wound, that is, the cut circular TPU film cannot be completely collected and stored.

[0004] Therefore, we proposed a multi-material TPU film processing device for breast patch to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a multi-material TPU film processing device for breast patch. When the TPU film needs to be cut, rolled and collected, the conveying and rolling mechanism is first used to drive the TPU film to be rolled and moved. When the TPU film moves to the film cutting position, the two hydraulic rods are directly started at the same time. At this time, the two hydraulic rods started will directly drive all the circular column cutters to move downward under the cooperation of two L-shaped limit blocks and the porous plate. Each circular column cutter that moves downward will cause the telescopic tube to extend under the cooperation of the corresponding circular block and the arc tube. When the circular column cutter contacts the TPU film and continues to move downward, the TPU film is directly cut stably under the action of a middle support plate, which is similar to the conventional method. At the same time, the two electromagnets are started at the same time. At this time, under the action of the sealed space formed by the rectangular sealing gasket, the first concave block, the sealing plate and the second concave block, the started electromagnet will move the corresponding slider toward it. At the same time, the moving slider will cause the air pressure inside the sealed space to change, and the cutting end of the circular ring column cutter of each opening will obtain suction. When the TPU film is cut, the circular TPU film remaining inside the circular ring column cutter will directly reach the first concave block for storage under the action of suction. When the circular ring column cutter moves back, the electromagnet is directly turned off. At this time, with the cooperation of the spring and the cylindrical block, the slider is automatically reset, and the TPU film is quickly collected and stored after cutting.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention is provided with a cutting and collecting mechanism. When the TPU film needs to be cut and collected, the conveying and winding mechanism is directly used to drive the TPU film to be wound and moved. When the TPU film moves to the film cutting position, the two hydraulic rods are directly started at the same time. The two hydraulic rods started at this time will drive all the circular column cutters on the porous plate to move vertically downward under the cooperation of the two L-shaped limit blocks. Each circular column cutter that moves vertically downward will make each telescopic tube extend under the cooperation of the circular block and arc tube corresponding to each circular column cutter. When the cutting end of the circular column cutter contacts the top of the TPU film and continues to move downward, under the action of a middle support plate, the TPU film is directly cut stably. At the same time, two electromagnets are started at the same time. The electromagnets started at this time will move the corresponding slider toward the corresponding rectangular hole under the cooperation of the corresponding rectangular hole. At the same time, the moving slider will also compress the spring. At the same time, the moving slider will change the air pressure inside the sealed space under the action of the sealed space formed by the rectangular sealing gasket, the first concave block, the sealing plate and the second concave block. The principle is the same as holding the syringe and pulling the rod to make the syringe port obtain strong suction. The cutting end of each opening of the circular cylindrical cutter also obtains suction. When the TPU film is cut, the circular TPU film remaining inside the circular cylindrical cutter will be directly transferred to the inside of the first concave block under the action of the suction of the cutting end of the circular cylindrical cutter, and stored on the top of the rectangular sealing gasket. When the circular cylindrical cutter moves back, the electromagnet is directly turned off. At this time, under the cooperation of the spring rebound force and the cylindrical block, the slider and the sealing gasket body are automatically reset. When the first concave block When a large amount of circular TPU film is collected on the top of the internal rectangular sealing gasket and needs to be released, the winding and die-cutting of the TPU film is stopped, the hand-tightening bolt is directly removed, and the L-shaped plate is used to drive the rectangular sealing gasket to move. When the rectangular sealing gasket moves, the circular TPU film rolled on the top of the rectangular sealing gasket will fall directly into the larger space near the bottom of the first concave block for collection. This method effectively improves the complete collection of the circular TPU film after the TPU film is die-cut, that is, effectively improves the utilization efficiency of the TPU film processing device.

[0019] 2. The present invention sets a conveying and winding mechanism. When the TPU film needs to be wound, one end of the TPU film is wound on one of the transmission rollers, and the film surface of the TPU film is placed on the other transmission roller. At the same time, the servo motor is turned on and the servo speed regulator is used to adjust the speed of the servo motor. Directly starting the servo motor will drive the two transmission rollers to rotate simultaneously under the cooperation of the two pulleys and a single belt to carry out the winding operation of the TPU film. When the TPU film with a narrow width needs to be wound and die-cut, the two hand screws are loosened first, and then the TPU film is wound according to the speed of the TPU film. The width of the TPU film is matched with the scale, and the connecting block is used to drive each corresponding set of slides to move inside the two hollow blocks respectively, and each set of moving slides will drive the corresponding limit plate to move. When the two limit plates are moved to the same distance relative to each other, the two hand screws can be tightened directly. Then the cutting end of the circular column cutter that is not inside the width of the TPU film is directly blocked with a sealing plug, and the cutting end of the circular column cutter inside the width of the TPU film can be kept open, which effectively ensures that the TPU film does not deviate at an angle during the moving rewinding and die-cutting.

[0033] according to Figure 2-4As shown, a discharge hole 223 is provided on the other side of the first concave block 201, and a baffle 224 is installed at the opening of the discharge hole 223. By setting the discharge hole 223, the circular TPU film for the nipple cover collected inside the first concave block 201 can be taken out.

[0034] according to Figure 2-4 and Figure 6 As shown, the rectangular sealing gasket 222 and the L-shaped plate 221 are both located between the bottom of the second concave block 211 and the top of the rectangular plate 220. By setting the rectangular plate 220, a supporting force can be provided for the L-shaped plate 221, that is, the top of the rectangular sealing gasket 222 can be in contact with the top of the second concave block 211 to form a seal.

[0035] according to Figure 1-4 and Figure 8 As shown, the conveying and winding mechanism 1 includes a workbench 101, the top of the workbench 101 and the bottom of the first concave block 201 are fixed, and two symmetrical transmission rollers 102 are rotatably connected between the two sides of the inner wall of the workbench 101. By setting the transmission rollers 102, the TPU film can be transmitted, and the TPU film can also be driven to perform a winding operation through the cooperation of the servo motor 103, the pulley 104, the workbench 101 and the belt.

[0036] according to Figure 8 As shown, a servo motor 103 is installed on the front surface of the workbench 101, one end of the servo motor 103 is fixed to the front surface of one of the drive rollers 102, and the outer surfaces of the two drive rollers 102 are fixedly sleeved with a pulley 104, and the two pulleys 104 are connected by a belt drive. By setting the servo motor 103, the pulley 104, the workbench 101 and the belt, the two drive rollers 102 can be driven to rotate synchronously.

[0037] according to Figure 8 As shown, a servo speed regulator 105 is installed on the front surface of the workbench 101 , and the servo speed regulator 105 is connected to the servo motor 103 via a wire. By setting the servo speed regulator 105 , the speed of the servo motor 103 can be set.

[0038] according to Figure 8 and Figure 9 As shown, three support plates 4 are fixed at equal distances between the two inner wall surfaces of the workbench 101, and the center line of the middle support plate 4 is on the same plane as the bottom center of multiple circular column cutters 205. By setting the support plates 4, the circular column cutters 205 can be ensured to perform stable and accurate die-cutting on the TPU film.

[0039] according to Figure 1 、 Figure 7 and Figure 8As shown, a limiting mechanism 3 is provided on the top of the conveying and winding mechanism 1. The limiting mechanism 3 includes eight support blocks 301, and the eight support blocks 301 are all installed on the top of the workbench 101 by bolts. The eight support blocks 301 are divided into four groups. A hollow block 302 is fixed between the opposite sides of each two groups of support blocks 301. By setting the support blocks 301, the hollow blocks 302 can be stably located in the middle position of the top of the workbench 101 without moving.

[0040] according to Figure 7 As shown, the top of each hollow block 302 is threaded with a hand screw 303, and the interior of each hollow block 302 is movably connected to a slide 304. The top of each slide 304 is embedded with a ruler 305, and the top of each slide 304 is fixed with a connecting block 306. The four connecting blocks 306 are divided into two groups. Through the digital ruler 305, the connecting block 306 can drive the slide 304 to move an accurate numerical distance.

[0041] according to Figure 7 and Figure 8 As shown, rectangular grooves 307 are provided on both sides of the inner wall of the workbench 101, and a limiting plate 308 is provided inside each rectangular groove 307. The four slides 304 are divided into two groups. The top of each group of slides 304 is fixed to the top of each limiting plate 308. By setting the limiting plates 308, the TPU film can be ensured to be more stable during winding and die-cutting without angular deviation.

[0042] The effect achieved by the entire mechanism is as follows: when it is necessary to make a TPU film for a breast mask, one end of the TPU film that needs to be rolled and die-cut is directly wound around one of the transmission rollers 102, and the film surface of the TPU film is placed on the other transmission roller 102, then the servo motor 103 is turned on, and the servo speed regulator 105 is used to set the speed adjustment program of the servo motor 103. When it is necessary to roll and die-cut a TPU film with a narrow width, the two hand screws 303 are loosened in sequence, and then one of the groups of connecting blocks 306 is directly moved according to the width of the TPU film and the matching of the ruler 305. At this time, the moving group of connecting blocks 306 will drive the corresponding group of slides 304 and the corresponding ruler 305 on each slide 304. When one set of slides 304 moves, the moving set of slides 304 will drive the corresponding limiting plate 308 to move out from the inside of the corresponding rectangular groove 307. When one side of the limiting plate 308 contacts one end of the TPU film, the movement of the limiting plate 308 is stopped, and the above steps are repeated to move the other limiting plate 308 to contact the other end of the TPU film. Then, the two hand screws 303 are directly tightened. At this time, the hand screws 303 can be used to tightly squeeze and fix the slide 304 inside the hollow block 302, and then the cutting end of the circular column cutter 205 that is not inside the width of the TPU film is directly blocked with the sealing plug 206. The cutting end of the annular column cutter 205 can be kept in an open state directly. When everything is ready, the servo motor 103 is started at this time. The started servo motor 103 will drive the two transmission rollers 102 to rotate at the same time under the cooperation of the two pulleys 104 and a single belt, and one of the rotating transmission rollers 102 will reel up the TPU film. At the same time, the two hydraulic rods 202 are directly started at the same time. The two hydraulic rods 202 started at this time will respectively drive the corresponding L-shaped limit blocks 203 to move downward, and the two L-shaped limit blocks 203 that move downward will drive the porous plate 204 to move vertically downward together. When the porous plate 204 moves vertically downward, all the annular column cutters 205 on the porous plate 204 will move vertically synchronously. The circular column cutters 205 that are not within the range of the TPU film will also drive the corresponding sealing plugs 206 to move. At this time, each circular column cutter 205 that moves vertically downward will make each telescopic tube 209 extend synchronously with the cooperation of the corresponding circular ring block 208 and the arc tube 207. When the cutting ends of all the circular column cutters 205 touch the top of the TPU film, the hydraulic rod 202 is used to drive the circular column cutters 205 to move downward. At this time, with the cooperation of a middle support plate 4, the TPU film is directly cut stably. At the same time, the two electromagnets 219 are started at the same time. At this time, the two electromagnets 219 that are started at the same time will cooperate with the corresponding rectangular holes 212.The corresponding slider 216 is driven to move toward the magnetic end of the electromagnet 219 inside the rectangular hole 212. At the same time, the moving slider 216 will also drive the cylindrical block 217 to move horizontally and stably under the cooperation of the limit groove 213 and the cylindrical groove 214. At the same time, each moving cylindrical block 217 will also cause the corresponding spring 218 to be compressed. When each annular column cutter 205 passes through the TPU film and the circular TPU film cut out is inside the annular column cutter 205, the moving slider 216 will be moved by the rectangular sealing gasket 222, the first concave block 2 01. The cooperation of the sealing space formed by the sealing plate 225 and the second concave block 211 directly changes the air pressure inside the sealed space. This principle is the same as the principle of holding a syringe and pulling the pull rod to make the syringe port obtain a strong suction. At this time, the cutting end of each opening of the circular column cutter 205 obtains suction. At this time, the circular column cutter 205 that obtains suction will directly transfer the circular TPU film inside it to the inside of the telescopic tube 209, then enter the inside of the arc tube 207, and finally directly enter the inside of the first concave block 201, and the rectangular sealing gasket 2 22 is stored at the top. When the annular column cutter 205 moves back under the action of the hydraulic rod 202, the two electromagnets 219 are directly closed at the same time. At this time, the two sliders 216 that have lost suction will automatically reset under the cooperation of the rebound force of the corresponding spring 218 and the cylindrical block 217. At the same time, the reset slider 216 will also drive the corresponding sealing pad body 215 to reset. When the circular TPU film collected on the top of the rectangular sealing pad 222 inside the first concave block 201 is too much and needs to be released, the winding and After die-cutting, directly remove the hand-tightening bolt 226 and use the L-shaped plate 221 to drive the rectangular sealing gasket 222 to move. When the rectangular sealing gasket 222 moves, the circular TPU film rolled up on the top of the rectangular sealing gasket 222 will directly fall into the larger space near the bottom of the first concave block 201 for collection. When the circular TPU film inside the first concave block 201 needs to be removed, the baffle 224 installed on the discharge hole 223 can be directly removed and it can be removed with tools. The processed circular TPU film can then be used on the nipple cover.

[0043] The servo motor 103 , the servo speed regulator 105 , the hydraulic rod 202 and the electromagnet 219 are all prior art and will not be further explained here.
