Description

Technical Field

[0001] This invention relates to the field of automated processing, and more particularly to a material receiving and turning feeding device and a fully automated straight conveyor belt processing equipment having the device. Background Technology

[0002] Inflatable products are among the most popular toys and household items, such as inflatable castles, inflatable pools, and inflatable tents. Some larger inflatable products are typically made of three layers of composite materials, with a middle layer called a strap layer that connects the upper and lower layers and creates tension between them. This tension in the straps greatly influences the shape of the product after inflation.

[0003] Traditional inflatable product manufacturing methods typically involve manually laying and layering materials, cutting them, and then feeding them into a pressing machine to compress the straps into shape. However, the manual layering method is not only inefficient but also suffers from poor alignment accuracy between upper and lower layers and between the straps; resulting in low production efficiency, high production costs, and poor product quality. Summary of the Invention

The first pulling clamp can move back and forth toward the cutting assembly. The first pulling clamp moves toward the cutting assembly and clamps the end of the intermediate fabric layer. Then it pulls the fabric layer backward a certain distance. The first cutter then cuts the intermediate fabric layer. Then the front and rear fixing clamps are released. The first pulling clamp then pulls the cut straight strap backward to below the feeding swing arm. The feeding swing arm rotates downward to above the straight strap, adsorbs and rotates the straight strap to a horizontal position, and then moves forward between the first low roller and the second high roller.

[0006] Furthermore, the flipping assembly also includes a lifting device, which is disposed between the cutting assembly and the first pulling clamp; the lifting device includes a lifting plate, the first pulling clamp places the straight conveyor belt on the lifting plate, the lifting plate drives the straight conveyor belt to rotate at a certain angle, and the feeding swing arm transfers the straight conveyor belt on the lifting plate.

The first cutter then cuts the middle fabric layer. The flipping assembly includes a first material pulling clamp and a feeding swing arm. The feeding swing arm is located above the first material pulling clamp, which can move back and forth toward the cutting assembly. The first material pulling clamp moves toward the cutting assembly and clamps the end of the middle fabric layer, then pulls the fabric layer backward a certain distance. The first cutter then cuts the middle fabric layer. Then the front and rear fixing clamps are released, and the first material pulling clamp pulls the cut straight strap backward to below the feeding swing arm. The feeding swing arm rotates downward to straighten the strap. Above the sling, the straight sling is attracted and rotated to a horizontal position, then moved forward to between the first low roller and the second high roller. The feeding device is equipped with multiple sets of feeding rollers, which feed the upper, middle and lower fabric layers respectively. The receiving and turning feeding device conveys the upper and lower fabric layers, cuts the middle fabric layer, and clamps the cut straight sling cover between the upper and lower fabric layers.

[0039] To make the objectives, technical solutions, and advantages of the invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0040] like Figures 1 to 18 As shown, this invention provides a fully automatic straight conveyor belt processing equipment 100 with a material receiving and flipping feeding device. It is used to automatically transport single-layer surface material, middle material, and bottom material, selectively using punching and pressing processes to form composite layer material, and finally cut it into finished straight conveyor belts. The fully automatic processing equipment includes, from front to back, a feeding device 20, a material receiving and flipping feeding device 10, a high-frequency pressing device 30, a cutting device 40, and a discharging device 50, and also includes a control system (not shown) that is signal-connected to each device.

[0041] The material receiving and flipping feeding device 10 includes a slide rail base 11, a first support frame 12, a punching assembly 13, a cutting assembly 14, and a flipping assembly 15. The first support frame 12 is movably mounted on the slide rail base 11, and the punching assembly 13, the cutting assembly 14, and the flipping assembly 15 are all mounted on the first support frame 12. Each component of the material receiving and flipping feeding device 10 can punch and cut the intermediate material and then feed it to subsequent processing sections via a flipping and gripping operation.

[0042] The blanking assembly 13 includes a first slide rail 131 mounted on a first support frame 12, a second slide rail 132 mounted on the first slide rail 131 that can slide back and forth, and two sets of blanking tables 133 mounted on the second slide rail 132 that can slide left and right and are arranged symmetrically. Each blanking table 133 includes a lower die 133a, an upper die 133b, and a first telescopic cylinder 133c that can extend and retract vertically. The upper die 133b and the first telescopic cylinder 133c are both located above the lower die 133a, with the first telescopic cylinder 133c mounted on the lower die 133a and the upper die 133b mounted at the bottom of the first telescopic cylinder 133c. When the two sides of the intermediate material are conveyed to the lower die 133a, the first telescopic cylinder 133c can drive the upper die 133b to press down and blank the intermediate material, blanking specific notches on both sides of the intermediate material. The punching table 133, located on the first slide rail 131 and the second slide rail 132, can adjust the punching interval by moving back and forth, and can also move left and right to handle punching middle sections of material of different widths.

[0043] The cutting assembly 14 includes a third slide rail 141, a first drive motor 142, a first cutter 143, a front fixing clamp 144, and a rear fixing clamp 145. The third slide rail 141 is mounted on the first support frame 12, and the first drive motor 142 is located on one side of the third slide rail 141. The first cutter 143 includes a first cutter holder 143a and a first cutter wheel 143b mounted on the first cutter holder 143a. The first cutter holder 143a is mounted on the third slide rail 141 and is poweredly connected to the first drive motor 142. The first cutter holder 143a can slide left and right along the third slide rail 141. Both the front clamp 144 and the rear clamp 145 include a lower clamp 144a, an upper clamp 144b, and a second telescopic cylinder 144c arranged sequentially from bottom to top. The upper clamp 144b is mounted on the bottom of the second telescopic cylinder 144c and can be moved up and down. The rear clamp 145 is located downstream of the front clamp 144, and the first cutter wheel 143b is located between the front clamp 144 and the rear clamp 145. When the middle section material is conveyed into the front clamp 144 and the rear clamp 145, the two clamps clamp and fix the two sides of the middle section material respectively. Then, the first cutter 143 moves from one end of the third slide rail 141 to the other end under the drive of the first drive motor 142. While the first cutter 143 moves, the cutter wheel on it cuts the middle section material between the front clamp 144 and the rear clamp 145, thereby cutting the middle section material into pieces.

[0044] The flipping assembly 15 includes a fourth slide rail 151, a first material pulling clamp 152, a second drive motor 153, a lifting device 154, a fifth slide rail 155, a third drive motor 156, and a feeding swing arm 157. The fourth slide rail 151, the second drive motor 153, the fifth slide rail 155, and the third drive motor 156 are all mounted on the first support frame 12. The first material pulling clamp 152 is mounted on the fourth slide rail 151 and is poweredly connected to the second drive motor 153. The first material pulling clamp 152 can slide back and forth along the fourth slide rail 151. The lifting device 154 is located between the cutting assembly 14 and the first pulling clamp 152. It includes a third telescopic cylinder 154a, a lifting bottom shaft 154b, two sets of lifting plates 154c, and a pneumatic hinge 154d. The third telescopic cylinder 154a is mounted on the first support frame 12. The lifting bottom shaft 154b is mounted on the top of the third telescopic cylinder 154a and can be moved up and down. The two ends of the two sets of pneumatic hinges 154d are respectively hinged to the front and rear sides of the lifting bottom shaft 154b and the two lifting plates 154c, and the pneumatic hinges 154d can drive the lifting plates 154c to flip up and down. The feeding swing arm 157 is located above the lifting device 154. It includes a swing arm frame 157a, a fourth drive motor 157b, a telescopic swing arm 157c, and a fourth telescopic cylinder 157d. The swing arm frame 157a is mounted on a fifth slide rail 155 and is powered by a third drive motor 156. The swing arm frame 157a can slide back and forth along the fifth slide rail 155. The fourth drive motor 157b is mounted on one side of the swing arm frame 157a. The telescopic swing arm 157c is mounted on the upper end of the swing arm frame 157a and is powered by the fourth drive motor 157b. The telescopic swing arm 157c can swing up and down along the axis in the left and right direction. The fourth telescopic cylinder 157d is mounted at the tail of the telescopic swing arm 157c and can drive the telescopic swing arm 157c to extend and retract.

[0045] The first material-pulling clamp 152 can work in conjunction with the feeding device 20 to pull the intermediate material from the front section to the rear section. While pulling, it also keeps the intermediate material taut and flat, ensuring the processing effect. The intermediate material, processed into sheet-like pieces by the cut component 14, is pulled by the first material-pulling clamp 152 onto the lifting device 154. The pneumatic hinge 154d drives the lifting plate 154c to lift the intermediate material on the plate at an angle. Simultaneously, the telescopic swing arm 157c rotates and swings downwards, using negative pressure to grip the intermediate material before rotating and swinging upwards to reset. Finally, the telescopic swing arm 157c, driven by the swing arm frame 157a and its own telescopic operation, delivers the intermediate material to the subsequent section for processing.

[0046] The receiving and turning feeding device 10 further includes a feeding assembly 16, which includes three sets of first driven rollers 161: upper, middle, and lower. The upper first driven roller 161 includes a first high-position roller 161a and a first low-position roller (not shown), and the lower first driven roller 161 includes a second low-position roller 161b and a second high-position roller (not shown). The first high-position roller 161a and the second low-position roller 161b are both located on the first support frame 12 and are arranged vertically opposite each other, with a large gap between them. The first low-position roller and the second high-position roller are both located at the entrance of the high-frequency pressing device 30 and are arranged vertically opposite each other, with a small gap between them. The surface of the first driven roller 161 is provided with a spiral thread from the end to the center. The receiving and turning feeding device 10 is also provided with several correction controllers 17, which are installed on one side of the first driven roller 161. The first driven roller 161 assists in conveying the top layer material and the bottom layer material. The threads on the driven roller provide an anti-slip effect, ensuring that the top layer material and the bottom layer material can be conveyed normally from the previous section to the next section. The deviation correction controller 17 can prevent the top layer material and the bottom layer material from becoming skewed during the conveying process, which could lead to insufficient product quality.

[0047] The punching table 133 also includes a material ejector clamp 133d, which is located on one side of the lower die 133a. A corresponding material ejector groove 133e is also provided on one side of the lower die 133a. After the punching assembly 13 punches the intermediate material, small pieces of scrap material will be left on the material ejector groove 133e. At this time, the material ejector clamp 133d can remove the scrap material from the lower die 133a through the notch in the groove, thus preventing excessive scrap material from accumulating on the die and affecting the punching process.

[0048] The feeding device 20 includes a second support frame 21, a bottom feeding assembly 22, a middle feeding assembly 23, a top feeding assembly 24, and several second driven rollers 25. The second support frame 21 has a stepped design, and the bottom feeding assembly 22, the middle feeding assembly 23, and the top feeding assembly 24 are sequentially mounted on the second support frame 21 in a stepped manner from bottom to top. The feeding device 20 can automatically convey the bottom material, middle material, and top material to the next processing section, and the stepped feeding assembly ensures that the conveying of each single layer of material does not interfere with each other.

[0049] The bottom feeding assembly 22, the middle feeding assembly 23, and the top feeding assembly 24 each include a mounting frame 231, a feeding roller 232, and a fifth drive motor 233. The mounting frame 231 is engaged with the second support frame 21. The feeding roller 232 is mounted on the mounting frame 231. The fifth drive motor 233 is mounted on one side of the mounting frame 231 and is poweredly connected to the feeding roller 232. Several second driven rollers 25 are mounted on the mounting frame 231 or the second support frame 21 and are all located downstream of the feeding roller 232. When the equipment starts running, the fifth drive motor 233 drives the feeding roller 232 to rotate, and the bottom, middle, and top materials on the feeding roller 232 are conveyed backward. The second driven rollers 25 make the conveying of each layer of material smoother.

[0050] The bottom feeding assembly 22, the middle feeding assembly 23, and the top feeding assembly 24 all include an automatic tension adjustment assembly 234. The automatic tension adjustment assembly 234 includes a counterweight roller 234a and two symmetrically arranged sliding rods 234b. The sliding rods 234b are vertically mounted on the second support frame 21. The counterweight roller 234a is located between the corresponding feeding roller 232 and the driven roller, with its two ends respectively sleeved on the sliding rods 234b on both sides and movable up and down along the sliding rods 234b. The surface of the second driven roller 25 is provided with a spiral thread from the end to the center. The fifth drive motor 233 is a variable frequency drive motor. The automatic tension adjustment assembly 234 uses the gravity of the counterweight roller 234a to press down on the single-layer material during the conveying process. Appropriate counterweights ensure that each single-layer material remains taut without tearing or damage, greatly improving the quality of the processed products.

[0051] The high-frequency pressing device 30 includes a third support frame 31, a lower electrode plate 32, an upper electrode plate 33, and a pressing cylinder 34. The lower electrode plate 32 is fixedly mounted on the third support frame 31. The pressing cylinder 34 is mounted on the top of the third support frame 31 and located above the lower electrode plate 32. The upper electrode plate 33 is mounted on the bottom of the pressing cylinder 34 and located above the lower electrode plate 32. A return spring 341 is also fitted on the pressing cylinder 34. The sheet-like middle section material processed from the receiving and turning feeding device 10 is sandwiched between the top layer material and the bottom layer material. Then, the pressing cylinder 34 drives the upper electrode plate 33 to press downward, causing the three single-layer materials to form a composite layer material. The return spring 341 on the pressing cylinder 34 can increase the pressing force, making the composite layer material formed by pressing more compact.

[0052] The bottom sides of the third support frame 31 are respectively provided with fifth telescopic cylinders 35, and one end of each of the two sets of fifth telescopic cylinders 35 is connected to the first support frame 12. The third support frame 31 is also provided with several third driven rollers 36, which are respectively located on the front and rear sides of the lower electrode plate 32 and the upper electrode plate 33. The surface of the third driven rollers 36 is provided with a spiral thread from the end to the center. The fifth telescopic cylinders 35 on the third support frame 31 can drive the first support frame 12 to slide on the slide rail base 11 by telescopic movement, thereby adjusting the distance between the material receiving and turning feeding device 10 and the high-frequency pressing device 30, so that the processing equipment can be adapted to produce and process straight conveyor belts of various specifications.

[0053] The material cutting device 40 includes a fourth support frame 41, a sixth slide rail 42, a conveying component 43, a fixed pressure component 44, a movable pressure component 45, and a cutting component 46. The sixth slide rail 42, the conveying component 43, and the fixed pressure component 44 are all mounted on the fourth support frame 41, while the movable pressure component 45 and the cutting component 46 are all mounted on the sixth slide rail 42. The conveying component 43 on the material cutting device 40 can continue to convey the composite layer material processed by the high-frequency pressing device 30 to the next processing stage. The fixed pressure component 44 and the movable pressure component 45 cooperate to make the conveyed composite layer material smoother, while the cutting component 46 is responsible for cutting the composite layer material into segments into finished products.

[0054] The conveying assembly 43 includes two drive rollers 431, a conveyor belt 432, and a sixth drive motor 433. The two drive rollers 431 are mounted opposite each other at both ends of the fourth support frame 41. The conveyor belt 432 is sleeved on the two drive rollers 431. The sixth drive motor 433 is mounted on the middle of one side of the fourth support frame 41 and is poweredly connected to the two drive rollers 431. The composite layer material after being stamped by the high-frequency pressing device 30 falls onto the conveyor belt 432. The sixth drive motor 433 drives the conveyor belt 432 to roll, thereby conveying the composite layer material backward.

[0055] The fixed pressure assembly 44 includes a fixed bracket 441, a fixed pressure plate 442, and several sixth telescopic cylinders 443. The fixed bracket 441 is installed at one end of the fourth support frame 41 and is located above the conveyor belt 432. The several sixth telescopic cylinders 443 are installed on the fixed bracket 441, and the fixed pressure plate 442 is installed at the bottom of the sixth telescopic cylinders 443 and is located between the fixed bracket 441 and the conveyor belt 432. When the composite layer material enters from one end of the conveyor assembly 43, it also passes through the fixed pressure assembly 44. At this time, due to the preset height difference between the conveyor belt 432 and the fixed pressure plate 442, it is just enough to accommodate the composite layer material of the current thickness to pass through, so the composite layer material will be flattened after passing through the fixed pressure assembly 44. The sixth telescopic cylinders 443 can drive the fixed pressure plate 442 to move up and down, thereby adjusting the height difference between the conveyor belt 432 and the fixed pressure plate 442 to accommodate the passage of composite layer materials of different thicknesses.

[0056] The movable pressure assembly 45 includes a movable support 451, a movable pressure plate 452, and several seventh telescopic cylinders 453. The movable support 451 is mounted on the sixth slide rail 42 and can slide back and forth. The movable support 451 is located above the conveyor belt 432. The several seventh telescopic cylinders 453 are mounted on the movable support 451. The movable pressure plate 452 is mounted at the bottom of the seventh telescopic cylinders 453 and is located between the movable support 451 and the conveyor belt 432. When the composite material stops on the conveyor belt 432, the movable pressure assembly 45 above it can further flatten the composite material by sliding back and forth. The seventh telescopic cylinders 453 can also adjust the height difference between the conveyor belt 432 and the movable pressure plate 452, thereby flattening composite materials of different thicknesses.

[0057] The cutting assembly 46 includes a cutting frame 461, a seventh slide rail 462, a movable handwheel 463, a seventh drive motor 464, a second cutter 465, and several fourth driven rollers 466. The cutting frame 461 is mounted on the sixth slide rail 42 and passes through a conveyor belt 432. The seventh slide rail 462 is located on the cutting frame 461. The seventh drive motor 464 and the movable handwheel 463 are respectively located at the left and right ends of the cutting frame 461, wherein the movable handwheel 463 can drive the cutting frame 461 to slide back and forth along the sixth slide rail 42. The second cutter 465 includes a second cutter holder 465a and a second cutter wheel 465b mounted on the second cutter holder 465a. The second cutter holder 465a is mounted on the seventh slide rail 462 and is poweredly connected to the seventh drive motor 464. The second cutter holder 465a can slide left and right along the seventh slide rail 462. Several fourth drive rollers 431 are mounted on the bottom of the cutting frame 461, and the conveyor belt 432 passes between the fourth drive rollers 431. After being flattened by the fixed pressure assembly 44 and the movable pressure assembly 45, the composite material can be divided into multiple finished products by the cutting assembly 46. The second cutter 465 of the seventh drive motor 464 slides left and right along the seventh slide rail 462, and the cutter wheel can cut the composite material. By adjusting the moving handwheel 463, the cutting frame 461 can be positioned at different positions on the conveyor belt 432, thereby cutting out finished products of different lengths of straight hanging belts. The several fourth driven rollers 466 can maintain a certain distance between the conveyor belt 432 and the composite material at the cutting point, avoiding accidental cutting of the conveyor belt 432 by the cutter wheel and causing damage to the equipment.

[0058] The feeding device 50 includes a fifth support frame 51, an eighth slide rail 52, a lifting platform 53, an eighth drive motor 54, a second material pulling clamp 55, and a ninth drive motor 56. The eighth slide rail 52, lifting platform 53, eighth drive motor 54, and ninth drive motor 56 are all mounted on the fifth support frame 51. The second material pulling clamp 55 is mounted on the eighth slide rail 52 and is poweredly connected to the ninth drive motor 56. The second material pulling clamp 55 can slide back and forth along the eighth slide rail 52. The lifting platform 53 includes a material placement plate 531, a plurality of lifting slide rods 234b, and drive shafts 533. The plurality of lifting slide rods 234b are respectively erected within the fifth support frame 51. The four corners of the material placement plate 531 are respectively inserted through the plurality of lifting slide rods 234b. The plurality of drive shafts 533 are respectively poweredly connected to the eighth drive motor 54 and the material placement plate 531. The second material pulling clamp 55 can pick up the cut straight strap products from the cutting device 40 and pull them onto the lifting platform 53 under the drive of the ninth drive motor 56. When there are too many straight strap products piled up on the lifting platform 53, the eighth drive motor 54 will drive the material placement plate 531 to descend a certain height, so that the second material pulling clamp 55 can continue to pile the straight strap products onto the lifting platform 53.

[0059] In this invention, both the receiving and turning feeding device 10 and the unloading device 50 are equipped with several detection sensors (not shown in the figure), each of which is connected to the control system signal. The detection sensors on the receiving and turning feeding device 10 can detect and determine the operating status of each component within the device, while the detection sensors on the unloading device 50 can detect and determine the stacking height of the straight-strip products on the lifting platform 53. The installation of these detection sensors makes the automated operation of the processing equipment more precise and efficient, and the quality of the processed straight-strip products is also higher.

[0060] In operation, the bottom layer, middle layer, and top layer are first placed on the corresponding feeding components of the feeding device 20. Driven by the fifth drive motor 233, the feeding roller 232 conveys the corresponding single-layer material to the receiving and turning feeding device 10. While conveying the single-layer material, the tension automatic adjustment component 234 on the feeding device 20 applies appropriate pressure to the corresponding single-layer material through the gravity roller, ensuring that each single-layer material remains taut throughout the conveying process.

[0061] Next, the top and bottom layers of material are conveyed to the receiving and turning feeding device 10 and move to the subsequent processing section under the auxiliary drive of the driven roller. During the auxiliary drive of the driven roller, the correction controller 17 also prevents the top and bottom layers of material from tilting or shifting. The middle section material is further processed by various components on the receiving and turning feeding device 10. The punching component 13 punches special notches on both sides of the middle section material, and the scrap left by punching is removed by the ejector clamp 133d. The long middle section material after punching is cut into narrow pieces by the cutting component 14. During cutting, the front fixed clamp 144 and the rear fixed clamp 145 fix both sides of the middle section material, and then the cutter wheel slides in the center along the left and right direction to cut the middle section material between the two fixed clamps. As for the flipping component 15, the lifting device 154 lifts the sheet-like middle section material obliquely so that the telescopic swing arm 157c can grab it. The telescopic swing arm 157c swings down to grab the middle section material, then swings back to reset and sends the middle section material into the high-frequency pressing device 30 through sliding and telescopic movement.

[0062] The middle section material fed into the high-frequency pressing device 30 is sandwiched between the top layer material and the bottom layer material, and the three single-layer materials are all located between the upper electrode plate 33 and the lower electrode plate 32. Under the downward pressing action of the upper electrode plate 33 driven by the pressing cylinder 34 and the high-frequency ultrasonic welding action between the upper electrode plate 33 and the lower electrode plate 32, the three single-layer materials are tightly bonded to form an integrated composite layer material.

[0063] Then, the composite material is conveyed backward through the cutting device 40 by the conveyor belt 432 assembly. When the composite material first enters the conveyor belt 432, the fixed pressure assembly 44 flattens it once, and then the movable pressure assembly 45 performs a second leveling by sliding back and forth. The two work together to ensure that the composite material on the conveyor belt 432 remains flat, avoiding irregularities in the final straight strap product. After being leveled by the movable pressure assembly 45, the composite material is divided into segments of straight strap products by the cutting assembly 46. During cutting, the position of the cutting frame 461 is adjusted by shaking the moving handwheel 463 so that it can cut the straight strap product of the desired length. Then, the second cutting wheel 465b slides in the left and right direction to complete the cutting.

[0064] Finally, the finished straight conveyor belts, after being cut, are pulled by the second material clamp 55 and stacked on the material placement plate 531 of the lifting platform 53. When the stacking height of the products on the material placement plate 531 is too high, the eighth drive motor 54 will automatically lower the material placement plate 531 to an appropriate height to allow for the stacking of subsequent products. When the material placement plate 531 is completely lowered to the bottom and the stacking height of the straight conveyor belt products on it reaches the upper limit, the equipment operation is paused and all products on the material placement plate 531 are transferred. When the material placement plate 531 is completely raised, the equipment is restarted for a new round of production processing.

[0065] In summary, the beneficial effects of the material receiving and turning feeding device and the fully automatic straight conveyor belt processing equipment with the device of the present invention are as follows: by designing the material receiving and turning feeding device 10, which is operated in full automatic control by the control system, in conjunction with the feeding device 20, the high-frequency pressing device 30, the cutting device 40 and the unloading device 50, the production of straight conveyor belts is replaced from low-efficiency manual processing to high-efficiency automatic processing by equipment. This not only greatly improves production efficiency, but also significantly enhances the quality of the processed products, while also saving a lot of labor costs. The present invention is highly practical and has strong promotional significance.

[0066] The embodiments described above illustrate only one implementation of the invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the invention. Therefore, the scope of protection of the invention patent should be determined by the appended claims.
