Description

Technical Field

[0001] This utility model relates to the field of textile processing technology, and in particular to a quick edge rolling device for curtains. Background Technology

[0002] The curtain quick edge curler is an automated auxiliary device used in the curtain processing field. Its main function is to quickly curl and press the edges of curtains, forming a neat curled structure, preventing edge unraveling and wear, and improving the appearance and lifespan of the curtain. This equipment, used in conjunction with a curtain cutting production line, significantly reduces the time and cost of curtain edge processing.

[0003] Traditional curtain quick hemming machines consist of a main frame for guiding the fabric, simple size limiting components, and basic fabric folding components. In use, the operator inserts the curtain fabric into the guide channel of the hemming machine, and the folding components form a folded edge on the fabric. Then, a sewing machine is used to sew along the folded edge. However, due to the simple structural design, it lacks stable limiting and precise guidance for the fabric, resulting in fabric deviation during sewing, inconsistent hemming width, difficulty in guaranteeing sewing quality, and low efficiency.

[0004] The existing technology has been improved by adding a graduated adjustment dial to accurately measure the distance between the lines and the edge, and by adopting an export belt edge design to make the seam straighter, thus improving the hemming accuracy. However, in actual use, when the operator is operating the sewing machine or adjusting the fabric, the hemming device may be accidentally touched by the hand or other parts, causing the hemming device to shift position due to the accidental touch. This causes the folding trajectory of the curtain fabric to deviate from the preset position, ultimately resulting in uneven hemming and fabric damage after the curtain is sewn, making it difficult to meet the requirements of high-quality curtain production.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides a quick curtain hemming device, including a base plate 1, which provides an installation support base for all components of the device. A connecting block 2 is fixedly threaded to the rear top of the base plate 1. A connecting block 3 is provided on the front top of the base plate 1. A hemming device 4 is provided on the left end of the connecting block 3. A fixing mechanism 5 is provided on the rear top of the base plate 1, which limits and fixes the connecting block 3 during the hemming process to prevent the connecting block 3 from shifting. An adjustment mechanism 6 is provided on the top of the connecting block 3, which is used to adjust the position of the hemming device 4. A rotating component 7 is provided at the rear end of the connecting block 3. The rotation of the connecting block 3 around the connecting block 2 facilitates the adjustment of the hemming angle.

[0036] The fixing mechanism 5 includes a mounting plate 501 for mounting and fixing a first round shaft 503 to the base plate 1 via screws 502. The bottom end of the mounting plate 501 is fixedly connected to the rear top end of the base plate 1 to ensure the stability of the mounting plate 501 on the base plate 1. Two screws 502 are threadedly connected to the top end of the mounting plate 501 to detachably fix the mounting plate 501 to the top end of the base plate 1 for easy subsequent maintenance and disassembly. The bottom ends of the two screws 502 penetrate the top end of the mounting plate 501 and are threadedly connected to the top end of the base plate 1 to enhance the firmness of the connection between the mounting plate 501 and the base plate 1. A first round shaft 503 is fixedly connected to the bottom end of the mounting plate 501. A second round shaft 504 is rotatably connected to the left and right ends of the first round shaft 503. The first round shaft 503 and the second round shaft 504 cooperate to achieve a rotatable connection. 3. Fixed shafts 505 are rotatably connected to the inner walls of the two round shafts 504, which provide axial support for the rotation of the round shafts 503 and 504. Limiting plates 506 are fixedly connected to the front ends of the two round shafts 504. The round shafts 504 are used to drive the limiting plates 506 to rotate, thereby opening and closing the limiting plates 506. The limiting plates 506 are used to directly contact the connecting block 3 and limit the connecting block 3 to prevent the hemming machine 4 from moving during operation. An outer groove 507 is provided on the front side of the top of the bottom plate 1 to accommodate the bottom end of the limiting plate 506. Magnets 508 are fixedly connected to the inner wall of the outer groove 507 and the front bottom end of the limiting plate 506. The magnets 508 fix the bottom end of the limiting plate 506 in the outer groove 507 through magnetic adsorption, thereby enhancing the fixing effect of the limiting plate 506 on the curtain.

[0037] Specifically, the mounting plate 501 is fixed to the base plate 1 by screws 502. The screws 502 pass through the mounting plate 501 and are threadedly connected to the base plate 1, achieving detachable fixing and stable support of the mounting plate 501 on the base plate 1. A first round shaft 503 is fixed to the bottom end of the mounting plate 501, and its left and right ends are rotatably connected to a second round shaft 504. A fixed shaft 505 passes through the inner walls of the first round shaft 503 and the second round shaft 504, providing axial support for their relative rotation, allowing the second round shaft 504 to rotate around the first round shaft 503. The front end is fixed to the limiting plate 506. As the second round shaft 504 rotates, it drives the limiting plate 506 to open and close. The outer groove 507 of the base plate 1 accommodates the bottom end of the limiting plate 506. The inner wall of the outer groove 507 and the magnet 508 at the bottom end of the limiting plate 506 are magnetically attracted to fix the bottom end of the limiting plate 506 in the outer groove 507. The limiting plate 506 contacts the second connecting block 3. Through the above cooperation, the second connecting block 3 is limited, preventing the edge curler 4 from moving when it is working. The attraction of the magnet 508 enhances the fixing effect of the limiting plate 506.

[0038] Reference Figure 3 , Figure 4 and Figure 6The adjusting mechanism 6 includes a housing 601 for housing and protecting the moving block 602 and providing guidance for the sliding of the moving block 602. The housing 601 is rotatably fixedly connected to the right end of the hemming tool 4 to ensure that the housing 601 moves synchronously with the hemming tool 4. The inner wall of the housing 601 is slidably connected to the front and rear ends of the connecting block 3 to realize the movement of the housing 601 along the front and rear ends of the connecting block 3. The top end of the connecting block 3 is slidably connected to the moving block 602, which is used to drive the housing 601 and the hemming tool 4 to move, thereby realizing the adjustment of the hemming position. The top end of the moving block 602 is fixedly connected to the top end of the inner wall of the housing 601. The top of the movable block 602 is threadedly connected to a threaded block 603, which drives the movable block 602 to move up and down through the threaded connection, thereby fixing the position of the movable block 602. The top of the threaded block 603 is fixedly connected to a limiting block 604, which is used to limit the downward movement distance of the threaded block 603 and prevent the threaded block 603 from moving too far downward. The bottom end of the limiting block 604 is slidably connected to the top of the outer wall of the housing 601 to ensure the stability when the limiting block 604 drives the threaded block 603 to rotate. The top of the limiting block 604 is fixedly connected to a handle 605, which is used to facilitate the operator to rotate the limiting block 604 and the threaded block 603, thereby improving the ease of operation.

[0039] Specifically, the outer shell 601 moves synchronously by rotating and fixing the right end of the hemming device 4. Its inner wall is slidably connected to the front and rear ends of the connecting block 3, providing a basis for its own forward and backward movement. At the same time, the outer shell 601 accommodates and guides the sliding block 602. The sliding block 602 is slidably connected to the top of the connecting block 3, and its top is fixed to the top of the inner wall of the outer shell 601. This allows the sliding block 602 to drive the outer shell 601 and the hemming device 4 to move synchronously, thereby adjusting the hemming position. The top of the sliding block 602 is threadedly connected to the threaded block 603. When 603 rotates, it drives the moving block 602 to move up and down through the threaded engagement, thereby fixing the position of the moving block 602 to lock the adjusted rolled edge position. The limiting block 604 fixed at the top of the threaded block 603 has its bottom end slidably connected to the top of the outer wall of the outer shell 601, which not only ensures the stability when the limiting block 604 drives the threaded block 603 to rotate, but also limits the downward movement distance of the threaded block 603 to prevent excessive downward movement. The handle 605 fixed at the top of the limiting block 604 provides a force point for the operator to easily rotate the limiting block 604 and the threaded block 603.

[0040] Reference Figure 2 , Figure 3 and Figure 4The rotating assembly 7 includes a first ring 701, which is used to cooperate with a second ring 702 to achieve a rotatable connection. The left end of the first ring 701 is fixedly connected to the right end of the first connecting block 2, fixing the first ring 701 and the first connecting block 2 into one piece. The top end of the first ring 701 is rotatably connected to the second ring 702, which is used to drive the second connecting block 3 to rotate around the first ring 701. The top end of the second ring 702 is fixedly connected to the rear end of the second connecting block 3 to ensure that the second ring 702 and the second connecting block 3 rotate synchronously. The inner wall of the second ring 702 is rotatably connected to a bolt 703, which is used to fix the second connecting block 3 after it rotates to a suitable angle to prevent the second connecting block 3 from rotating arbitrarily. The bottom end of the bolt 703 is threadedly connected to the top end of the base plate 1. Multiple scale lines 8 are fixedly connected to the top of connecting block 2 3. The scale lines 8 provide position references for the movement of moving block 602, facilitating precise adjustment of the rolled edge position. An indicator needle 9 is fixedly connected to the left end of moving block 602. The indicator needle 9 points to the scale lines 8, allowing the operator to clearly read the movement position of moving block 602 and improve adjustment accuracy. A baffle 10 is fixedly connected to the front end of connecting block 1 2. The baffle 10 limits the rear end of housing 601, preventing housing 601 from moving excessively backward. The top end of baffle 10 engages with the rear end of housing 601, enhancing the limiting effect of baffle 10 on housing 601.

[0041] Specifically, the first ring 701 is fixed to the first connecting block 2 as a whole, and the second ring 702 is rotatably connected to the first ring 701 and fixed to the second connecting block 3, so that the second connecting block 3 can rotate around the first ring 701. The bolt 703 connects the second ring 702 to the base plate 1, and fixes its position after the second connecting block 3 rotates to a suitable angle to prevent random rotation. The scale line 8 on the second connecting block 3 cooperates with the indicator needle 9 of the moving block 602. The indicator needle 9 points to the scale line 8, providing a position reference for the movement of the moving block 602, making it easy for the operator to read the movement position and achieve precise adjustment of the rolled edge position. The baffle 10 of the first connecting block 2 engages with the rear end of the outer shell 601 to limit the outer shell 601 and prevent it from moving too far backward, thus enhancing the limiting effect.

[0042] Reference Figure 1 , Figure 3 and Figure 7A side plate 11 is fixedly connected to the left end of connecting block 2 3 to limit the finished curtain. The left end of side plate 11 is fixedly connected to the right end of the hemming device 4 to enhance the firmness of the connection between connecting block 2 3 and hemming device 4. Two slots 12 are opened on the rear side of the top of the base plate 1. Slots 12 are used to accommodate and limit the nut 13 to prevent the nut 13 from moving at will. At the same time, the position of the base plate 1 can be adjusted. Nuts 13 are slidably connected to the inner walls of the two slots 12. Nuts 13 are used to cooperate with the external structure to fix the base plate 1 and improve the installation stability of the entire device. A limiting post 14 is fixedly connected to the top right side of the base plate 1. The limiting post 14 is used to cooperate with the second slot 15 to guide and limit the movement of the second connecting block 3. The bottom end of the second connecting block 3 is provided with the second slot 15, which is used to accommodate the limiting post 14 and provide a guide track for the movement of the second connecting block 3. The top end of the limiting post 14 is slidably connected to the inner wall of the second slot 15 to ensure that the second connecting block 3 moves stably along the limiting post 14 and to prevent the second connecting block 3 from deviating when it moves.

[0043] Specifically, the left end of the side plate 11 is fixedly connected to the right end of the edge roller 4, and the right end is fixedly connected to the left end of the connecting block 2 3. This connection not only limits the position of the finished curtain, but also enhances the connection between the connecting block 2 3 and the edge roller 4. The two slots 12 on the rear side of the top of the bottom plate 1 are slidably engaged with the nuts 13. The slots 12 accommodate and limit the nuts 13 to prevent them from moving arbitrarily. At the same time, the position of the bottom plate 1 is adjusted by the sliding of the nuts 13 in the slots 12. The nuts 13 cooperate with the external structure to fix the bottom plate 1, improving the overall installation stability of the device. The limiting post 14 on the right side of the top of the bottom plate 1 is slidably engaged with the slot 2 15 at the bottom of the connecting block 2 3. The slot 2 15 accommodates the limiting post 14 to form a moving guide track for the connecting block 2 3. The limiting post 14 guides and limits the movement of the connecting block 2 3 through this engagement, ensuring that the connecting block 2 3 moves stably along the limiting post 14 and preventing it from deviating during movement.

[0044] Working principle: The base plate 1 is installed on the needle plate of the sewing machine by the nut 13. The curtain is edged by the edge roller 4. At this time, the mounting plate 501 is fixed to the base plate 1 by two screws 502. The first round shaft 503 and the second round shaft 504 form a rotating pair through the fixed shaft 505. The limiting plate 506 at the front end of the second round shaft 504 can rotate flexibly around the fixed shaft 505 and is in a ready-to-close state. When the operator rotates the limiting plate 506, the second round shaft 504 rotates around the fixed shaft 505 of the first round shaft 503, so that the front end of the limiting plate 506 rotates downward until its bottom end is embedded in the outer groove 507 on the front side of the top of the base plate 1. At this time, the inner wall of the outer groove 507 and the magnet 508 at the bottom front end of the limiting plate 506 attract each other. The limiting plate 506 is held in place by magnetic force. 6. The limit plate 506 is firmly fixed in the outer groove 507, forming a closed state. The limit plate 506 directly contacts the connecting block 3, which restricts the movement of the connecting block 3 by physical blocking, thereby fixing the position of the hem roller 4 and forming a protective barrier. When the hem roller 4 needs to be maintained or adjusted, the operator can apply external force to overcome the attraction force of the magnet 508 and rotate the limit plate 506 upward. The second round shaft 504 rotates in the opposite direction around the fixed shaft 505, so that the limit plate 506 is removed from the outer groove 507 and the limitation on the connecting block 3 is released. When the staff operates around the equipment, even if there is an accidental touch, the limit plate 506 will bear the external force first, avoiding the external force from acting directly on the hem roller 4, preventing the hem roller 4 from being displaced or abnormally moved due to accidental touch, thereby protecting the curtain from damage.

[0045] Furthermore, when the hemming device 4 is not in the same position as the sewing machine needle plate, the operator holds the handle 605 and rotates the handle 605 to drive the limiting block 604 fixed at its bottom to rotate synchronously. The limiting block 604 ensures no deviation during rotation by sliding with the top of the outer wall of the housing 601, and directly limits the downward stroke of the threaded block 603 to prevent excessive downward movement of the threaded block 603 from damaging the parts. Since the threaded block 603 and the top of the moving block 602 are threadedly connected, and the moving block 602 is doubly limited by the receiving guide structure of the housing 601 and the sliding constraint of the connecting block 2 3, the rotation of the threaded block 603 is converted into the up and down movement of the moving block 602. When it is necessary to adjust the position of the hemming device 4, the handle 605 is rotated in the opposite direction to move the threaded block 603 upward and release the tension. The moving block 602 is pressed and fixed. At this time, the hemming device 4 is pulled, and the hemming device 4 will drive the outer shell 601 to move synchronously. At this time, the inner wall of the outer shell 601 and the front and rear ends of the connecting block 2 3 slide together, providing precise guidance for the movement of the outer shell 601 and preventing shaking. At the same time, the outer shell 601 will drive the internal moving block 602 to slide synchronously along the top of the connecting block 2 3 until the hemming device 4 is fully matched with the position of the sewing machine needle plate. After the position is calibrated, the handle 605 is rotated forward to drive the threaded block 603 to move down until the bottom end of the threaded block 603 tightly abuts against the connecting block 2 3. At this time, the threaded block 603 firmly presses the moving block 602 onto the connecting block 2 3, restricting any displacement of the moving block 602, thereby completely locking the position of the hemming device 4 and preventing displacement due to vibration during sewing.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
