Description

Technical Field

[0001] This invention relates to the field of automated tarpaulin processing equipment, and more specifically, to an integrated device and processing method for automatic buckling and folding of double wings after transverse heat sealing of tarpaulin. Background Technology

[0002] The current mainstream process for processing finished tarpaulins is as follows: longitudinal heat sealing and splicing of a single narrow tarpaulin → longitudinal buckling → longitudinal folding → transverse cutting → transverse heat sealing and edge binding of the two wings → buckling of the two wings → transverse folding of the two wings → transverse square folding and forming. The processes that existing equipment can complete include: longitudinal heat sealing and splicing of a single narrow tarpaulin → longitudinal buckling → longitudinal folding → transverse cutting → transverse heat sealing and edge binding of the two wings.

[0003] Regarding the processing steps after heat sealing the transverse wings of the tarpaulin, existing technologies have the following significant drawbacks: (1) After the heat-sealed edges are wrapped, the two wings of the tarpaulin are unfolded. Manual operation is required to complete the transfer, positioning, buckling, folding and other operations. This not only results in high labor costs, low processing efficiency and poor product consistency, but also insufficient folding precision, which can easily lead to problems such as offset and wrinkling, affecting the quality of the finished product. (2) Under the manual operation mode, each processing step is independent of each other and lacks a linkage mechanism for the entire process of transfer, correction, buckling and folding, which makes it impossible to achieve automated continuous production and difficult to adapt to the needs of large-scale production.

[0004] To address the shortcomings of the existing technologies, this invention proposes an integrated device and processing method for automatic buckling and folding of double wings after transverse heat sealing of tarpaulin, which realizes fully automated operation, significantly improves production efficiency and finished product quality, and fills a technological gap in the industry.

The folding platform located below the third fabric clamping assembly is a discrete structure. The folding mechanism includes a fabric limiting unit for fixing the rear wing of the tarpaulin, a front folding unit for folding the front wing of the tarpaulin, and a rear folding unit for folding the rear wing of the tarpaulin.

[0010] Preferably, the distribution limiting unit includes: The distribution cylinder is mounted on the upright of the frame; The cloth-limiting roller is rotatably connected between the two columns of the frame; The fabric limiting bracket is set on the fabric limiting roller.

[0011] Preferably, the front folding unit includes: The front folding fabric support is connected to the frame via a support guide rail.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0022] like Figure 1 As shown, the present invention provides an integrated device for automatic buckling and folding of double wings after transverse heat sealing of tarpaulin, comprising: a frame 1, wherein a buckling module 2, a temporary storage module 3 and a folding module 4 are sequentially arranged on the frame 1 along the tarpaulin conveying direction; The buckling module 2 is used to clamp the tarpaulin after it has been heat-sealed on both sides laterally, to correct the tarpaulin's deviation and to buckle it on both sides laterally. The buckled tarpaulin is then sent to the temporary storage module 3. The temporary storage module 3 is used to temporarily store the tarpaulin after the buckles have been fastened; The folding module 4 is used to fold the front and rear wings of the tarpaulin to form a long, multi-layered structure.

[0023] After the tarpaulin is heat-sealed on both sides laterally, it enters the device. First, the fastening module 2 clamps the tarpaulin and moves it horizontally, and performs edge position correction. After the correction is completed, the tarpaulin's two lateral wings are automatically fastened. After the fastening is completed, the fastening module 2 returns to the initial position. The tarpaulin with the buckles fastened is held horizontally by the temporary storage module 3 and temporarily stored in the temporary storage module 3. The setting of the temporary storage module 3 enables the buckling module 2 and the preceding horizontal heat sealing and folding devices to work continuously without waiting for the completion of the subsequent horizontal double-wing folding process, thus ensuring the continuity and efficiency of the overall operation. When the folding module 4 needs to perform folding operations, it clamps the tarpaulin temporarily stored in the temporary storage module 3 and moves it horizontally to the folding station. Then, it folds the front wing and the rear wing of the tarpaulin in sequence, and finally folds the tarpaulin into a long strip of multi-layered tarpaulin.

[0024] The beneficial effects of the above technical solution are as follows: (1) Significantly improved production efficiency: This invention extends the intermediate temporary storage logic (temporary storage module 3) to the longitudinal folding process and the transverse edge binding process, realizing the synchronous parallel operation of the preceding and following processes. The preceding equipment does not need to stop and wait for the following process to complete. Comparing the continuous serial operation system designed in the preceding process with the separate parallel operation system of this invention, taking a tarpaulin with a longitudinal length of 4 meters as an example: The preceding continuous series operation system ("→" indicates the process direction): longitudinal folding (14 seconds) → transverse heat sealing and edge wrapping (13 seconds) → transverse buckling (13 seconds) → transverse double wing folding (19 seconds); The total time for horizontal heat sealing, horizontal buckling, and horizontal double wing folding is 45 seconds. The vertical folding process can only be started after the above processes have been running for 30 seconds. The total processing time for a single tarpaulin is determined by the total time of the above three processes, which is 45 seconds. The present invention separates the parallel operation system ("→" indicates the process direction): longitudinal folding (14 seconds) → temporary storage platform for fabric (5 seconds) → transverse heat sealing and binding (13 seconds) → temporary storage platform for fabric (6 seconds) → transverse buckling (13 seconds) → temporary storage platform for fabric (6 seconds) → transverse double-wing folding (19 seconds); To match the 19-second time required for lateral double-wing folding, a temporary storage platform was added for 5 seconds after the longitudinal folding process (14 seconds), a temporary storage platform was added for 6 seconds after the lateral heat sealing and edge wrapping process (13 seconds), and a temporary storage platform was added for 6 seconds after the lateral buttoning process (13 seconds). This enabled the synchronous parallel operation of each process, with the total processing time for a single tarpaulin being only 19 seconds, improving efficiency by approximately 58% compared to the previous continuous series system. Fully automated process: It realizes integrated operation of tarpaulin clamping and transfer, correction, fastening, temporary storage and double wing folding, without human intervention, filling the technological gap in the industry; High folding precision: The folding module 4 can be precisely positioned, and with the coordinated action of the front wing folding and the rear wing folding, the tarpaulin is folded neatly, without offset or wrinkles, which significantly improves the quality of the finished product. Simple structure and controllable cost: The main power of the equipment is cylinder drive, which has a low failure rate, is easy to maintain and runs stably. Compared with complex hydraulic drive or servo drive structures, the manufacturing cost is greatly reduced, which facilitates large-scale promotion and application. Strong production line connectivity: It can be seamlessly connected with the preceding longitudinal folding, transverse cutting, and double-sided heat sealing edge wrapping equipment to form a complete automated tarpaulin production line without the need for major modifications to the existing preceding equipment, making it highly adaptable.

[0025] like Figure 2 As shown, in one embodiment, the buckle module 2 includes: The first fabric clamping assembly 21 is connected to the top of the frame 1 via the first synchronous belt guide rail 22 and is used to transport tarpaulin; The first synchronous belt guide rail 22 is driven by the first servo motor to drive the first fabric clamping assembly 21 to move horizontally. The first fabric clamping assembly 21 includes a first cylinder 211 connected to the first synchronous belt guide rail 22. The output end of the first cylinder 211 is provided with a first fabric clamping unit 212. The first cylinder 211 and the first fabric clamping unit 212 are linked together to drive the first fabric clamping unit 212 to move up and down, thereby realizing the clamping and placement of the tarpaulin. The first crossbeam platform 23, located below the first fabric clamping assembly 21, is a discrete structure that provides space for the movement of the first fabric clamping assembly 21. The primary correction unit 24 and the secondary correction unit 25 are arranged sequentially along the tarpaulin conveying direction and are located on both sides of the first crossbeam platform 23 for correcting the edge position of the tarpaulin. The horizontal fastening components 26, which are set on both sides of the first crossbeam platform 23, are equipped with photoelectric detectors on their upper parts. The horizontal fastening components 26 are used to automatically fasten the two horizontal wings of the tarpaulin.

[0026] The first fabric clamping unit 212 is a discrete cylinder-driven clamp.

[0027] After the tarpaulin is heat-sealed on both sides laterally, it enters the work area of ​​the buckle module 2. The first servo motor drives the first synchronous belt guide rail 22 to rotate, which drives the first cloth clamping assembly 21 connected to it to move horizontally along the tarpaulin conveying direction to the cloth receiving position. At this time, the first cylinder 211 drives the first cloth clamping unit 212 to move downward, and the first cloth clamping unit 212 clamps the tarpaulin. Then, the first synchronous belt guide rail 22 continues to drive the first cloth clamping assembly 21 to move horizontally. The tarpaulin passes sequentially through the primary correction unit 24 and the secondary correction unit 25 located on both sides of the first crossbeam platform 23. The primary correction unit 24 performs preliminary edge position correction on the tarpaulin, and the secondary correction unit 25 performs fine correction on the basis of the primary correction, accurately correcting the edge position of the tarpaulin to ensure the accuracy of subsequent buckling and folding. The first crossbeam platform 23 adopts a discrete structure design, and sufficient clearance is reserved in the gaps to allow the lifting and clamping actions of the first cloth clamping unit 212, ensuring that the cloth clamping action is carried out smoothly without interference. After the correction is completed, the first fabric clamping assembly 21 transports the tarpaulin to the working area of ​​the horizontal edge fastening assembly 26. The photoelectric detector set on the upper part of the horizontal edge fastening assembly 26 positions the two horizontal wings of the tarpaulin and accurately identifies the edge position and fastening point position of the two wings of the tarpaulin. According to the signal feedback of the photoelectric detector, the horizontal edge fastening assembly 26 automatically fastens the two horizontal wings of the tarpaulin. After the tarpaulin is fastened, the first tarpaulin clamping unit 212 releases the tarpaulin, and the fastened tarpaulin falls onto the first crossbeam platform 23 or is received by the subsequent temporary storage module 3. Then the first tarpaulin clamping assembly 21 returns to the initial receiving position along the first synchronous belt guide rail 22, ready to receive the next tarpaulin, thus realizing continuous cycle operation.

[0028] like Figure 3 As shown, in one embodiment, the temporary storage module 3 includes: The second fabric clamping assembly 31 is connected to the top of the frame 1 via the second synchronous belt guide rail 32 and is used to transport the tarpaulin. The second synchronous belt guide rail 32 is driven by the second servo motor to drive the second fabric clamping assembly 31 to move horizontally. The second fabric clamping assembly 31 includes a second cylinder 311 connected to the second synchronous belt guide rail 32. The output end of the second cylinder 311 is provided with a second fabric clamping unit 312. The second cylinder 311 and the second fabric clamping unit 312 are linked together to drive the second fabric clamping unit 312 to move up and down, thereby realizing the clamping and placement of the tarpaulin. The storage platform 33, located below the second fabric clamping assembly 31, is used to temporarily store the tarpaulin after the buckles have been fastened. The second crossbeam platform 34, which is a discrete structure, is located on the side of the fabric storage platform 33 near the fabric folding module 4, and is used to provide space for subsequent fabric clamping operations.

[0029] The second fabric clamping unit 312 is a discrete cylinder-driven clamp.

[0030] After the fastening module 2 completes the fastening operation of the tarpaulin, the fastened tarpaulin is transported to the work area of ​​the temporary storage module 3. The second servo motor drives the second synchronous belt guide rail 32 to move, causing the second cloth clamping assembly 31 connected to it to move horizontally along the tarpaulin conveying direction to the cloth receiving position (close to the fastening module 2). At this time, the second cylinder 311 drives the second cloth clamping unit 312 to move downward, and the second cloth clamping unit 312 clamps the fastened tarpaulin. Then, the tarpaulin is transported to the storage platform 33. The second clamping unit 312 releases the tarpaulin, and the tarpaulin is temporarily stored on the storage platform 33. Then the second clamping assembly 31 returns to the initial position, ready to receive the next tarpaulin with the buckles fastened. The temporary storage module 3 continuously receives and temporarily stores the tarpaulin after the buckle has been completed, enabling the buckle module 2 and the preceding transverse heat sealing and edge wrapping device and longitudinal folding device to work continuously without waiting for the folding module 4 to complete the folding operation; the second crossbeam platform 34 is a discrete structure and is located on the side of the storage platform 33 close to the folding module 4, providing operating space for the clamping action of the folding module 4. The folding module 4 can clamp the temporarily stored tarpaulin at the second crossbeam platform 34 and transport it to the folding station for folding. One or more tarpaulins can be temporarily stored on the storage platform 33. By reasonably designing the capacity of the storage platform 33, the speed difference between the preceding and following processes can be effectively balanced.

[0031] like Figure 4 As shown, in one embodiment, the fabric folding module 4 includes: The third fabric clamping assembly 41 is connected to the top of the frame 1 via the third synchronous belt guide rail 42 and is used to transport the tarpaulin. The third synchronous belt guide rail 42 is driven by a third servo motor to drive the third fabric clamping assembly 41 to move horizontally. The third fabric clamping assembly 41 includes a third cylinder 411 connected to the third synchronous belt guide rail 42. The output end of the third cylinder 411 is provided with a third fabric clamping unit 412. The third cylinder 411 and the third fabric clamping unit 412 are linked together to drive the third fabric clamping unit 412 to move up and down, thereby realizing the clamping and placement of the tarpaulin. The folding platform 43, located below the third fabric clamping assembly 41, is a discrete structure. The folding mechanism includes a fabric limiting unit 5 for fixing the rear wing of the tarpaulin, a front folding unit 6 for folding the front wing of the tarpaulin, and a rear folding unit 7 for folding the rear wing of the tarpaulin.

[0032] When the folding module 4 is working, the third servo motor drives the third synchronous belt guide rail 42 to rotate, which drives the third clamping assembly 41 to move to the second crossbeam platform 34 of the temporary storage module 3. The third cylinder 411 drives the third clamping unit 412 to move downward to clamp the temporarily stored tarpaulin. The third synchronous belt guide rail 42 drives the third clamping assembly 41 to move the tarpaulin horizontally to the top of the folding platform 43 and place the tarpaulin on the folding platform 43. The folding platform 43 adopts a discrete structure at the corresponding positions of the front folding unit 6 and the rear folding unit 7, which provides operating space for the operation of each unit in the subsequent folding mechanism. After the tarpaulin is placed on the folding platform 43, the folding mechanism starts to work. The limiting unit 5 first acts to press and fix the rear wing of the tarpaulin on the folding platform 43 to prevent the rear wing from shifting during the folding of the front wing. Then, the front folding unit 6 acts to fold the front wing of the tarpaulin, folding the front wing of the tarpaulin towards the top of the tarpaulin body. After the front wing is folded, the limiting unit 5 removes the pressing on the rear wing of the tarpaulin. The rear folding unit 7 acts to fold the rear wing of the tarpaulin, folding the rear wing of the tarpaulin towards the top of the tarpaulin body. After the front wing is folded and the rear wing is folded, the tarpaulin is folded into a regular long strip multi-layer structure. The folding module 4, through the orderly coordination of the limiting unit 5, the front folding unit 6, and the rear folding unit 7, realizes the step-by-step and orderly folding of the front and rear wings of the tarpaulin, ensuring the regularity and consistency of the folding effect.

[0033] like Figure 5 and Figure 7 As shown, in one embodiment, the distribution limiting unit 5 includes: The distribution limiting cylinder 51 is mounted on the column 11 of the frame 1; The limiting roller 52 is rotatably connected between the two columns 11 of the frame 1; Among them, the cloth limiting roller 52 is mounted on two columns 11 via bearings; The fabric limiting bracket 53 is set on the fabric limiting roller 52. The fabric limiting roller 52 and the fabric limiting bracket 53 are driven to rotate synchronously by the fabric limiting cylinder 51. It is used to fix the rear wing of the tarpaulin on the folding platform 43.

[0034] One end of the fabric limiting cylinder 51 is hinged to the column 11, and the other end is hinged to the fabric limiting roller 52. The extension and retraction of the fabric limiting cylinder 51 drives the fabric limiting roller 52 to rotate.

[0035] After the tarpaulin is placed on the folding platform 43 by the third fabric clamping assembly 41, the folding process begins. The fabric limiting unit 5 is activated first, and the fabric limiting cylinder 51 drives the fabric limiting roller 52 to rotate around its axis. The fabric limiting bracket 53 on the fabric limiting roller 52 rotates synchronously with the fabric limiting roller 52. The fabric limiting roller 52 is rotatably connected between the two columns 11 of the frame 1, and its rotation center line is set along the transverse direction of the tarpaulin. As the fabric limiting roller 52 rotates, the fabric limiting bracket 53 rotates from the initial position to the working position, applying a pressing force to the rear wing of the tarpaulin on the folding platform 43, pressing and fixing the rear wing of the tarpaulin on the folding platform 43, preventing the rear wing of the tarpaulin from shifting during the subsequent folding of the front wing, ensuring neat folding, and providing assurance for folding accuracy. After the front wing is folded, when the rear wing needs to be folded, the fabric limiting cylinder 51 drives the fabric limiting roller 52 to rotate in the opposite direction. The fabric limiting bracket 53 rotates back to the initial position synchronously with the fabric limiting roller 52, removing the pressure on the rear wing of the tarpaulin and releasing the rear wing of the tarpaulin, so that the rear folding unit 7 can perform the folding operation on the rear wing of the tarpaulin.

[0036] like Figure 5 and Figure 7 As shown, in one embodiment, the front folding unit 6 includes: The front folding support 61 is connected to the frame 1 via the support guide rail 62. The frame 1 is equipped with a longitudinal drive cylinder 63, the extension end of which is connected to the front folding support 61. The longitudinal drive cylinder 63 can drive the front folding support 61 to move along the support guide rail 62. The front folding panel 64 is connected to the front folding support 61 via a front folding drive assembly, which can drive the front folding panel 64 to complete the folding of the front wings of the tarpaulin.

[0037] The front folding support 61 is connected to the frame 1 via the support guide rail 62. The front folding support 61 can move longitudinally (perpendicular to the tarpaulin conveying direction) along the support guide rail 62 under the drive of the longitudinal drive cylinder 63. In the initial state, the front folding support 61 is located at one end of the support guide rail 62 (away from the tarpaulin); after the limiting unit 5 completes the pressing and fixing of the rear wing of the tarpaulin, the front folding unit 6 starts to work. The telescopic end of the longitudinal drive cylinder 63 is connected to the front folding support 61, driving the front folding support 61 to move along the support guide rail 62 towards the tarpaulin. After the front folding support 61 moves into place, the front folding drive component starts to operate, driving the front folding plate 64 to rotate, folding the front wing of the tarpaulin from the unfolded position to the top of the tarpaulin body, completing the folding of the front wing of the tarpaulin; the front folding plate 64 is located below the folding platform 43, completing the folding of the front wing from bottom to top. The front folding plate 64 is also a discrete structure, corresponding to the discrete structure of the folding platform 43, to avoid interference during folding.

[0038] like Figure 8 and Figure 9As shown, the front folding drive assembly further includes: The front folding drive roller 65 and the front folding roller 66 are mounted on the same two front support columns via bearings. The front support columns are connected to the front folding bracket 61. The front folding drive roller 65 and the front folding roller 66 are connected by a first drive chain 67. The front folding plate 64 is mounted on the front folding roller 66. The front folding cylinder 68 is connected at one end to the front folding bracket 61 and at the other end to the front folding drive roller 65. It is used to provide rotational power to the front folding drive roller 65, and drive the front folding roller 66 to rotate through the first drive chain 67, thereby driving the front folding plate 64 to complete the folding of the tarpaulin front wing.

[0039] The front folding cylinder 68 is hinged at both ends to the front folding bracket 61 and the front folding drive roller 65, respectively. The front folding cylinder 68 drives the front folding drive roller 65 to rotate through its extension and retraction.

[0040] After the folding support 61 moves longitudinally into place, the front folding cylinder 68 applies a driving force to the front folding drive roller 65, causing the front folding drive roller 65 to rotate. The front folding drive roller 65 transmits the rotational motion to the front folding roller 66 through the first drive chain 67. The front folding roller 66 drives the front folding plate 64 fixed on it to rotate synchronously. During the rotation, the front folding plate 64 applies a force to the front wing of the tarpaulin, folding the front wing of the tarpaulin from the unfolded position to the top of the tarpaulin body, thus completing the folding of the front wing.

[0041] After the front wing is folded, the front folding panel 64 remains in the folded position. When the rear wing of the tarpaulin is folded, the longitudinal drive cylinder 63 is activated, which drives the front folding support 61 to move slowly longitudinally away from the tarpaulin along the support guide rail 62. This smoothly pulls the front folding panel 64 out of the folded front wing of the tarpaulin. The pulling process is carried out at a constant speed to avoid pulling the tarpaulin and causing folding deformation. After pulling out, the front folding unit 6 is reset as a whole, ready for the next folding operation.

[0042] like Figures 6-8 As shown, in one embodiment, the back folding unit 7 includes: The rear folding drive roller 71 and the rear folding roller 72 are mounted on two identical rear support columns via bearings. The rear support columns are connected to the frame 1. The rear folding drive roller 71 and the rear folding roller 72 are connected by a second drive chain 73. The rear folding plate 74 is mounted on the rear folding roller 72; The rear folding cylinder 75 is connected at one end to the frame 1 and at the other end to the rear folding drive roller 71. It is used to provide rotational power to the rear folding drive roller 71, and drive the rear folding roller 72 to rotate through the second drive chain 73, thereby driving the rear folding plate 74 to complete the folding of the tarpaulin rear wings.

[0043] The two ends of the back folding cylinder 75 are hinged to the frame 1 and the back folding drive roller 71, respectively. The back folding cylinder 75 drives the back folding drive roller 71 to rotate through its extension and retraction.

[0044] After the front wing is folded and the fabric limiting unit 5 removes the pressure on the rear wing of the tarpaulin, the rear folding unit 7 starts to work. The rear folding cylinder 75 applies driving force to the rear folding drive roller 71, driving the rear folding drive roller 71 to rotate. The rear folding drive roller 71 transmits the rotational motion to the rear folding roller 72 through the second drive chain 73. The rear folding roller 72 drives the rear folding plate 74 fixed on it to rotate synchronously. During the rotation, the rear folding plate 74 applies force to the rear wing of the tarpaulin, folding the rear wing of the tarpaulin from the unfolded position to above the folded front wing of the tarpaulin, folding the rear wing of the tarpaulin symmetrically to ensure that the folded size of the rear wing is consistent with that of the front wing and fits tightly, thus completing the rear wing folding. After the rear wing is folded, the rear folding cylinder 75 of the rear folding unit 7 drives the rear folding drive roller 71 to rotate in the opposite direction, and drives the rear folding roller 72 and the rear folding plate 74 to rotate back to the initial position through the second drive chain 73.

[0045] like Figures 1-6 As shown, in one embodiment, the frame 1 includes: a plurality of columns 11, the upper part of which is connected by a plurality of upper crossbeams 12 and a plurality of upper longitudinal beams 13, and the lower part of which is connected by a plurality of lower crossbeams 14 and a plurality of lower longitudinal beams 15. The first fabric clamping assembly 21, the second fabric clamping assembly 31 and the third fabric clamping assembly 41 are respectively disposed on the corresponding upper longitudinal beam 13; Platform support columns 16 are provided between the first crossbeam platform 23, the cloth storage platform 33, and the folding platform 43 and the lower longitudinal beam 15; The two lower longitudinal beams 15 corresponding to the folding module 4 are provided with guide rail beams 17, and the support guide rail 62 is arranged between the two guide rail beams 17; the rear support column is arranged on the two lower longitudinal beams 15 corresponding to the folding module 4.

[0046] The frame 1 serves as the basic load-bearing structure of the entire device. It consists of multiple columns 11 as vertical support components. The upper part of the columns 11 is connected by multiple upper horizontal beams 12 and multiple upper vertical beams 13 to form a top frame structure. The lower part of the columns 11 is connected by multiple lower horizontal beams 14 and multiple lower vertical beams 15 to form a bottom frame structure. The top frame and the bottom frame are connected by the columns 11 to form an overall spatial frame, providing a stable installation foundation and load-bearing support for each functional module. The first fabric clamping component 21 of the snap-on module 2 is installed on the upper longitudinal beam 13 corresponding to the snap-on module 2 via the first synchronous belt guide rail 22. The second fabric clamping component 31 of the temporary storage module 3 is installed on the upper longitudinal beam 13 corresponding to the temporary storage module 3 via the second synchronous belt guide rail 32. The third fabric clamping component 41 of the folding module 4 is installed on the upper longitudinal beam 13 corresponding to the folding module 4 via the third synchronous belt guide rail 42. Each fabric clamping component is set on the upper longitudinal beam 13, utilizing the upper space for clamping and horizontal conveying of the tarpaulin, effectively utilizing the space of the frame 1. The first crossbeam platform 23, the cloth storage platform 33, and the folding platform 43 are respectively connected to the corresponding lower longitudinal beam 15 through the platform support column 16. The platform support column 16 provides vertical support for each platform, so that each platform is set at a suitable height above the lower longitudinal beam 15, which is convenient for the placement and temporary storage of the tarpaulin, and also provides reasonable travel space for the up and down movement of each cloth clamping component. The two lower longitudinal beams 15 corresponding to the folding module 4 are provided with guide rail beams 17, and the support guide rail 62 is set between the two guide rail beams 17, providing longitudinal guidance and support for the front folding support 61 of the front folding unit 6. The rear support columns are set on the two lower longitudinal beams 15 corresponding to the folding module 4, providing installation support for the rear folding drive roller 71 and the rear folding roller 72 of the rear folding unit 7.

[0047] This invention provides a processing method for automatically fastening and folding the double wings of a tarpaulin after transverse heat sealing. The method utilizes the integrated device described in this invention for automatically fastening and folding the double wings of the tarpaulin after transverse heat sealing, and includes: The first fabric clamping component 21 of the buckle module 2 clamps the tarpaulin after it has been heat-sealed on both sides laterally and moves it horizontally. It then passes through the first correction unit 24 and the second correction unit 25 in sequence to complete the edge position correction. After calibration, the tarpaulin is conveyed to the horizontal edge fastening unit 26 by the first clamping assembly 21. The two horizontal wings of the tarpaulin are positioned by the photoelectric detector, and the horizontal edge fastening unit 26 completes the automatic fastening of the horizontal edge of the tarpaulin. After the fastening is completed, the first clamping assembly 21 releases the tarpaulin and returns to the initial position along the first synchronous belt guide rail 22, ready to receive the next tarpaulin. The tarpaulin with the buckles fastened is held by the second clamping component 31 of the temporary storage module 3 and moved horizontally to the storage platform 33 of the temporary storage module 3 for temporary storage. The temporary storage module 3 continuously stores the tarpaulin, so that the buckling module 2 and the preceding horizontal heat sealing edge device and vertical folding device can work continuously without waiting for the subsequent horizontal double wing folding process, thus ensuring the overall work efficiency. The third fabric clamping assembly 41 of the fabric folding module 4 moves to the second crossbeam platform 34 of the temporary storage module 3 to clamp the temporarily stored tarpaulin and transport it to the folding platform 43 of the fabric folding module 4. The tarpaulin rear wing on the folding platform 43 is pressed by the fabric limiting unit 5, and then the front wing of the tarpaulin is folded by the front folding unit 6. After the front wing is folded, the fabric limiting unit 5 removes the pressure on the rear wing of the tarpaulin, and the rear wing of the tarpaulin is folded by the rear folding unit 7.

[0048] Furthermore, the above processing method also includes: After the rear wing is folded, the rear folding unit 7 remains in the folded position, and then the front folding plate 64 of the front folding unit 6 moves horizontally and longitudinally to be removed from the tarpaulin. After the front folding panel 64 is removed from the tarpaulin, the rear folding unit 7 returns to its initial position.

[0049] The above processing method is as follows: the tarpaulin after being heat-sealed on both sides is held by the first clamping assembly 21 of the buckle module 2, the first cylinder 211 drives the first clamping unit 212 to move downward to clamp the tarpaulin, and the first servo motor drives the first synchronous belt guide rail 22 to move the first clamping assembly 21 to clamp the tarpaulin horizontally along the tarpaulin conveying direction; during the movement, the tarpaulin first passes through the first correction unit 24, which performs preliminary edge position correction on the tarpaulin, and then the tarpaulin passes through the second correction unit 25, which performs fine correction on the basis of the first correction, so that the edge positions of the two lateral wings of the tarpaulin are precisely aligned. After calibration, the first fabric clamping assembly 21 continues to transport the tarpaulin to the horizontal edge fastening unit 26. The photoelectric detector on the upper part of the horizontal edge fastening unit 26 positions the two horizontal wings of the tarpaulin, accurately locating the edge position and fastening position of the two wings. According to the signal feedback from the photoelectric detector, the horizontal edge fastening unit 26 automatically fastens the two horizontal wings of the tarpaulin. After fastening, the first fabric clamping unit 212 releases the tarpaulin and places it on the left side of the first crossbeam platform 23. Then, the first fabric clamping assembly 21 returns to the initial position along the first synchronous belt guide rail 22, ready to receive the next tarpaulin. The tarpaulin with the buckles fastened is held by the second clamping assembly 31 of the temporary storage module 3. The second cylinder 311 drives the second clamping unit 312 to clamp the tarpaulin. The second servo motor drives the second synchronous belt guide rail 32 to move the second clamping assembly 31 horizontally, transporting the tarpaulin to the storage platform 33 of the temporary storage module 3 for temporary storage. The temporary storage module 3 continuously stores the tarpaulin, enabling the buckling module 2 and the preceding transverse heat sealing and folding device and longitudinal folding device to work continuously without waiting for the completion of the subsequent transverse double-wing folding process, thus improving the overall work efficiency. The third clamping assembly 41 of the folding module 4 moves to the second crossbeam platform 34 of the temporary storage module 3 under the drive of the third servo motor. The third cylinder 411 drives the third clamping unit 412 to clamp the temporarily stored tarpaulin. The third synchronous belt guide rail 42 drives the third clamping assembly 41 to move the tarpaulin horizontally to the folding platform 43 of the folding module 4, and then places the tarpaulin on the folding platform 43. The fabric limiting unit 5 presses and fixes the rear wing of the tarpaulin on the folding platform 43. The fabric limiting cylinder 51 drives the fabric limiting roller 52 to rotate. The fabric limiting bracket 53 rotates synchronously with the fabric limiting roller 52 to the working position, pressing the rear wing of the tarpaulin onto the folding platform 43. Then, the front folding unit 6 is activated. The longitudinal drive cylinder 63 drives the front folding bracket 61 to move longitudinally along the bracket guide rail 62 into place. The front folding drive assembly drives the front folding plate 64 to rotate, folding the front wing of the tarpaulin to the top of the tarpaulin body, completing the front wing folding. After the front wing is folded, the front folding plate 64 remains in the folded position. The cloth limiting unit 5 removes the pressure on the rear wing of the tarpaulin. The cloth limiting cylinder 51 drives the cloth limiting roller 52 to rotate in the opposite direction. The cloth limiting bracket 53 returns to the initial position and releases the rear wing of the tarpaulin. Then, the rear folding unit 7 is activated. The rear folding cylinder 75 drives the rear folding drive roller 71 to rotate. The second drive chain 73 drives the rear folding roller 72 and the rear folding plate 74 to rotate, folding the rear wing of the tarpaulin over the folded front wing of the tarpaulin. After the rear wing is folded, the tarpaulin is folded into a long strip of multi-layer structure. After the rear wing is folded, the rear folding plate 74 of the rear folding unit 7 remains in the folded position. At the same time, the front folding plate 64 of the front folding unit 6 begins to perform the withdrawal action. The longitudinal drive cylinder 63 is started first, driving the front folding bracket 61 to move horizontally longitudinally along the bracket guide rail 62. The front folding plate 64 is pulled out horizontally from the front wing of the tarpaulin, avoiding disturbance to the folded tarpaulin during the withdrawal process. Then, the front folding drive assembly drives the front folding plate 64 to rotate in the opposite direction and return it to the initial position. After the front folding plate 64 is completely retracted, the rear folding unit 7 returns to its initial position. That is, the rear folding cylinder 75 is activated, driving the rear folding drive roller 71 to rotate in the opposite direction. This drives the rear folding roller 72 and the rear folding plate 74 back to their initial positions via the second drive chain 73. At the same time, the third cylinder 411 drives the third clamping unit 412 back to its initial height, and the third synchronous belt guide rail 42 drives the third clamping assembly 41 back to its initial position. The longitudinal drive cylinder 63 and the front folding cylinder 68 of the front folding unit 6 both return to their initial positions, and the front folding bracket 61 and the front folding plate 64 both return to their respective initial positions. The fabric limiting cylinder 51 of the fabric limiting unit 5 returns to its initial position, and the fabric limiting bracket 53 is in its initial position in the released state. After all units are reset, the folding module 4 enters the preparation state for the next work cycle, waiting to receive the next tarpaulin from the temporary storage module 3 for folding.
