[0041] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0042] Please refer to Figures 1 to 7 The present application provides a correction device 10 , which includes a conveying mechanism 11 and a correction mechanism 12 .

[0043] Specifically, the conveying mechanism 11 includes a first conveying unit 111 and a second conveying unit 112 which are used to convey curtains and are distributed side by side, and a splicing area is defined between the first conveying unit 111 and the second conveying unit 112; the correcting mechanism 12 includes a correcting piece 122, a steel rope 126, a power piece 124 and a clamping assembly 121 for clamping the curtains to be spliced, the clamping assembly 121 is fixed on the steel rope 126, the power piece 124 is configured to drive the steel rope 126 to operate in the splicing area to drive the clamping assembly 121 to move, so as to pull the clamped curtains to the specified position, the correcting piece 122 is arranged on the operating path of the steel rope 126, and is located at the entrance of the specified position, and the correcting piece 122 is configured to correct the curtains to be spliced.

[0044] Exemplarily, the first conveying unit 111 and the second conveying unit 112 are respectively used to convey two curtains to be spliced, and the area between the first conveying unit 111 and the second conveying unit 112 defines a splicing area. For ease of description, the first curtain and the second curtain to be spliced ​​are taken as an example for explanation, specifically: the first curtain and the second curtain are placed on the first conveying unit 111 and the second conveying unit 112 respectively, at which time the first curtain and the second curtain on the first conveying unit 111 and the second conveying unit 112 have a partial overlap (i.e., a splicing seam), and then under the action of the first conveying unit 111 and the second conveying unit 112, the first curtain and the second curtain are transported to the designated position for splicing and fixing, without manual pulling, which is conducive to reducing labor intensity and improving production efficiency. It should be noted that in order to ensure that the first curtain and the second curtain will not be misaligned front and back, resulting in poor splicing quality, the first conveying unit 111 and the second conveying unit 112 in this embodiment have the same operating speed.

[0045] In addition, it should be noted that the first conveying unit 111 and the second conveying unit 112 can adopt commonly used conveying components in the prior art, which will not be described in detail.

[0046] Exemplarily, the clamping assembly 121 is used to clamp the overlapping seam of the first curtain and the second curtain to ensure that the curtains are always in a straightened and adjusted state during the transportation of the first curtain and the second curtain, which can effectively prevent the curtains from deviating from the seam and causing misalignment or deviation, thereby reducing the splicing quality.

[0047] Exemplarily, the correction member 122 is used to automatically correct the seam before fixing it, to ensure that the seam can be adjusted to enter the splicing mechanism for splicing and fixing, to prevent the seam of the curtain from being misaligned or deviated, which may cause problems with the splicing quality components.

[0048] Here, it should be noted that the "designated position" mentioned above refers to the position where the seam of the curtain is fixed and glued by the seam device, which depends on the setting position of the seam device and is not specifically limited.

[0049] The correcting device 10 based on the above technical features uses the clamping assembly 121 to clamp the joints of the two curtains, and then uses the power member 124 to drive the steel rope 126 to operate, so as to drive the clamping assembly 121 to move, and then cooperates with the first conveying unit 111 and the second conveying unit 112 to pull the clamped curtain to the specified position, so that the curtain is always in a straightened and adjusted state, which can effectively prevent the curtain from deviating from the joints and prevent misalignment or deviation. At the same time, a correcting member 122 is set at the entrance of the specified position, so that a secondary correction is performed before the joints are fixed to ensure that the joint position is correct, which is conducive to improving the quality of curtain splicing.

[0050] In a possible embodiment, the correcting member 122 includes a base plate 1221 and a partition plate 1222, wherein the partition plate 1222 is vertically connected to the middle of the base plate 1221 to separate the base plate 1221 into a first area a and a second area b, and the height of the partition plate 1222 gradually increases along the moving trajectory of the curtain.

[0051] For example, since the height of the partition plate 1222 gradually increases along the moving trajectory of the curtains, when the two curtains are pulled, the splicing edges of the two curtains will slightly arch upward, and then smoothly enter the splicing device 20 for splicing, which can effectively avoid deformation of the splicing seams and ensure the quality of the splicing.

[0052] In a possible implementation, the top edge of the partition plate 1222 is arc-shaped, and the surfaces of the bottom plate 1221 and the partition plate 1222 are both smooth. In this way, the edges of the two spliced ​​pieces can be separated, which is conducive to the curtains being smoothly separated by the partition plate 1222.

[0053] In a possible embodiment, the correction mechanism 12 also includes a first winding wheel 125 and a second winding wheel 127, and the first winding wheel 125 and the second winding wheel 127 are respectively arranged at two ends of the splicing area, and the two ends of the steel rope 126 are connected to form a ring, and the steel rope 126 is respectively wound around the first winding wheel 125 and the second winding wheel 127, and the power output end of the power component 124 is connected to the first winding wheel 125.

[0054] Exemplarily, by respectively providing a first winding wheel 125 and a second winding wheel 127 at both ends of the splicing area, and connecting the two ends of the steel rope 126 to form a ring-shaped winding around the first winding wheel 125 and the second winding wheel 127, when the power member 124 drives the first winding wheel 125 to rotate, the steel rope 126 is pulled to run between the first winding wheel 125 and the second winding wheel 127, thereby pulling the clamping assembly 121 to move, ensuring that it can move synchronously with the first conveying unit 111 and the second conveying unit 112.

[0055] In a possible implementation manner, a connecting bar is further included, two ends of the connecting bar are connected to two ends of the steel rope 126, and the clamping assembly 121 is connected to the connecting bar.

[0056] In a possible embodiment, the clamping assembly 121 includes a base 1211 and a cloth-pinching arm 1212 hinged on the base 1211. A first mounting hole is provided on the base 1211, and a second mounting hole matching the first mounting hole is provided on the connecting strip. Thus, a fastener (such as a screw, etc.) is sequentially passed through the first mounting hole and the second mounting hole to fix the base 1211 on the connecting strip, thereby connecting the clamping assembly 121 to the steel rope 126, which has a simple structure and is easy to assemble and disassemble.

[0057] In a possible embodiment, it also includes a support plate 123, which is arranged in the splicing area, and the first winding wheel 125 and the second winding wheel 127 are installed below the two ends of the support plate 123, and a guide groove 123a is opened on the support plate 123 along its length direction; wherein, when the power member 124 drives the first winding wheel 125 to rotate, the steel rope 126 operates to pull the clamping assembly 121 to move along the opening direction of the guide groove 123a.

[0058] In the second aspect, the present application also provides a curtain splicing device, including the correction device 10 and the splicing device 20 of the above embodiment, the splicing device 20 is arranged behind the correction member 122, and is used to splice the curtain. The splicing device 20 includes a tape sticking mechanism and a tape cutting mechanism for cutting the tape.

[0059] Specifically, the tape sticking mechanism includes a lower belt 21, an upper belt 22, a guide belt assembly and a conduction assembly. The lower belt 21 is arranged between the first conveying unit 111 and the second conveying unit 112; the upper belt 22 is arranged directly above the lower belt 21 and can move up and down; the guide belt assembly includes a first guide wheel 271 and a second guide wheel 272, the first guide wheel 271 and the second guide wheel 272 are arranged obliquely above the upper belt 22, and a glue passage c is formed between the first guide wheel 271 and the second guide wheel 272; the transmission assembly 26 includes a conduction wheel 263, a wheel frame 261 and a driving power source 262, the driving power source 262 is arranged above the upper belt 22, and the output end of the driving power source 262 is inclined to point to the upper belt 22, the wheel frame 261 is connected to the output end of the power source, and the conduction wheel 263 is rotatably connected in the wheel frame 261. When the curtains to be spliced ​​are transferred between the lower belt 21 and the upper belt 22 , the driving power source 262 drives the wheel frame 261 to tilt close to the upper belt 22 , so as to drive the conductive wheel 263 to abut against the surface of the upper belt 22 and the first guide wheel 271 .

[0060] In a possible implementation, it further includes a clamping assembly 25. The clamping assembly 25 includes a pressing wheel 252 and a lifting power member 251. The lifting power member 251 is disposed above the lower belt 21 and in front of the upper belt 22. The output end of the lifting power member 251 is connected to a connecting frame, and the pressing wheel 252 is rotatably mounted on the connecting frame.

[0061] For example, before the spliced ​​curtain moves to the position between the upper belt 22 and the lower belt 21, the splicing seam of the curtain may be warped or bent, which may easily lead to poor quality of subsequent splicing. In this regard, the present application uses a lifting power member 251 to drive the connecting frame to continuously approach the lower belt 21, so that the pressure wheel 252 installed on the connecting frame moves toward the lower belt 21, until the pressure wheel 252 is pushed to a position where it can apply appropriate pressure to the splicing seam of the passing curtain, and then the lifting power member 251 stops working, so that the pressure wheel 252 can be used to press the splicing seam of the curtain, which can ensure that the splicing seam of the curtain is flat and straight before splicing, thereby ensuring the splicing quality of the curtain.

[0062] In addition, it should be noted that the lifting power member 251 can be a cylinder, or a power member in the prior art that can drive the connecting frame to lift, and there is no limitation on this.

[0063] In a possible implementation, a hot air blower 23 is further included. An outlet of the hot air blower 23 is connected to an air outlet pipe 24. The air outlet end of the air outlet pipe 24 is obliquely directed toward the upper belt 22 for blowing out hot air to heat the adhesive tape.

[0064] Exemplarily, the air outlet pipe 24 is connected to the air outlet of the hot air blower 23, and the air outlet end of the air outlet pipe 24 is tilted toward the upper belt 22, so that hot air can be blown toward the tape, thereby preheating the tape, thereby ensuring that the tape has better adhesion before being affixed to the joint of the curtain, and can be more firmly adhered to the joint of the curtain.

[0065] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
