Description

Technical Field

[0001] This application relates to the field of textile processing technology, and in particular to a blanket machine. Background Technology

[0002] In today's home textile industry, with the continuous improvement of people's living standards, the demand for home textiles such as blankets is increasing, placing higher demands on blanket production efficiency and quality. At the same time, advanced textile equipment helps drive the home textile industry towards intelligent and automated development, improving the overall technological level of the industry. In the past, the production process of blankets and other home textile products typically involved: first, cutting the blanket blank to a set size, and then performing edge sewing to seal the edges. The cutting stage generally involved using cutting equipment to cut the blanket blank into blanket units of the required size, while the edge sewing stage used sewing machines or edge sewing heads to complete the edge sewing operation of the blanket units. During this process, the blanket blank or blanket units needed to be transported and loaded onto the machine multiple times, requiring manual handling or transport equipment for repeated handling and positioning to ensure that the blankets were accurately cut and sewn.

[0003] In the process of implementing this application, it was found that the technology has at least the following problems: each transportation process requires a certain amount of time and manpower, and multiple transportation operations increase production costs and reduce production efficiency. Summary of the Invention

[0004] In order to reduce the number of handling operations during blanket processing, reduce time and labor costs, reduce blanket production costs, and improve production efficiency, this application provides a blanket machine.

[0005] The blanket machine provided in this application adopts the following technical solution: A blanket making machine includes a horizontal frame and a vertical frame. The length direction of the horizontal frame is parallel to the X-axis, and the length direction of the vertical frame is parallel to the Y-axis. One end of the horizontal frame faces the side wall of the end of the vertical frame. The bottom of the other end of the horizontal frame is provided with a blanking platform for placing blanket blanks. Several guide rollers are rotatably arranged on the horizontal frame to guide the blanket blanks from the blanking platform towards the direction close to the vertical frame. A set of first sewing heads is symmetrically arranged on both sides of the horizontal frame for sewing the two sides of the blanket blanks. The vertical frame is provided with a positioning mechanism and a cutting mechanism at one end close to the horizontal frame. The positioning mechanism is used to position the end of the blanket blank, and the cutting mechanism is used to cut off the blanket blank positioned by the positioning mechanism, forming a blanket unit. A set of second sewing heads is symmetrically arranged on both sides of the vertical frame for sewing the two ends of the cut blanket unit.

[0006] By adopting the above technical solution, under the guidance of the guide rollers, the blanket blank is first hemmed on both sides in the Y-axis direction on the transverse frame, and then guided to the longitudinal frame. The positioning mechanism on the longitudinal frame precisely positions the ends of the blanket blank, and the cutting mechanism then cuts off the positioned parts of the blanket blank to form a blanket unit. Immediately afterwards, the second hemming heads located on both sides of the longitudinal frame hem the two ends of the blanket unit that were just cut (i.e., the two ends in the X-axis direction). In the entire process, the hemming of both sides, cutting, and hemming of both ends of the blanket are completed continuously and automatically on one machine, which significantly reduces the number of intermediate handling times of the blanket unit between the cutting and hemming processes, thereby effectively reducing time and labor costs, reducing production costs, and improving production efficiency.

[0007] Preferably, the longitudinal frame is divided into a cutting area, a waiting area, and a sewing area along its length. The positioning mechanism and the cutting mechanism are both located in the cutting area, and the second sewing head is located in the sewing area. A first conveyor is provided in the cutting area, a second conveyor is provided in the waiting area, and a third conveyor is provided in the sewing area. The first conveyor can convey blanket units to the second conveyor, and the second conveyor can convey blanket units to the third conveyor. The third conveyor conveys blanket units through the second sewing head. A detector is provided in the sewing area to detect whether there are blanket units in the sewing area. The detector is electrically connected to the second conveyor.

[0008] By adopting the above technical solution, the longitudinal frame is divided into a cutting area, a waiting area, and a sewing area. The first, second, and third conveyor rollers on the longitudinal frame enable the orderly flow of blanket units within the longitudinal frame. The detector can monitor the working status of the sewing area in real time: whether there are blanket units being sewn, and determine whether the sewing area is idle. If so, the second conveyor is controlled to send the blanket units from the waiting area into the sewing area, ensuring the continuity and efficiency of the sewing operation, avoiding congestion or idling, and further optimizing the production process.

[0009] Preferably, the detector is a through-beam photoelectric sensor.

[0010] By adopting the above technical solution, the through-beam photoelectric sensor has the advantages of high detection accuracy, fast response speed and strong anti-interference ability. It can reliably detect the presence status of the blanket unit in the seam area, ensuring the accuracy and timeliness of the conveying control.

[0011] Preferably, the positioning mechanism includes a head clamping assembly and an end clamping assembly, which are symmetrical on both sides of the longitudinal frame. The head clamping assembly is located on the side of the longitudinal frame away from the transverse frame. Both the head clamping assembly and the end clamping assembly include an upper mounting frame, a lower mounting frame, and a clamping drive. The upper mounting frame is located above the lower mounting frame. The first conveying component includes an upper conveying roller and a lower conveying roller. Several upper conveying rollers are rotatably arranged on the side wall of the upper mounting frame, and several lower conveying rollers are rotatably arranged on the side wall of the lower mounting frame. The axes of the upper and lower conveying rollers are parallel to the X-axis. The upper and lower conveying rollers can jointly clamp the blanket blank. The clamping drive drives the upper and lower mounting frames to move closer or further apart.

[0012] By adopting the above technical solution, the first end clamping component and the last end clamping component control the upper mounting frame and the lower mounting frame to move closer or further away through the clamping drive component, firmly clamping the first end (i.e., away from the transverse frame end) and the last end (closer to the transverse frame end) of the blanket blank, so that the blanket blank remains stable before cutting, providing a reliable positioning basis for precise cutting. The first conveying component set on the side wall of the upper mounting frame and the lower mounting frame can still rotate in coordination when the blanket unit is clamped, which facilitates the subsequent conveying of the blanket unit.

[0013] Preferably, the positioning mechanism further includes a pressing part and a pressing drive. The pressing part is higher than the upper mounting frame. The pressing part is located between the first end pressing assembly and the last end pressing assembly in the X-axis direction. The pressing drive is used to drive the pressing part to slide along the Z-axis direction. The pressing part can abut against the upper surface of the blanket blank between the first end pressing assembly and the last end pressing assembly and press down.

[0014] By adopting the above technical solution, under the action of the first end clamping component, the end of the blanket blank is first positioned, and the end clamping component does not move temporarily. Then, the downward driving component drives the downward pressing part to move down. The downward pressing part applies downward pressure to the blanket blank between the first end clamping component and the end clamping component. The blanket blank bends under the pressure of the downward pressing part. The blanket blank further enters the end clamping component between the ends of the blanket blank near the transverse frame. Finally, under the action of the end clamping component, the other end of the blanket blank to be cut is positioned, thereby determining the length of the blanket unit to be cut on the blanket blank.

[0015] Preferably, the pressing part includes a pressing frame and a roller. The pressing frame is fixed to the output end of the pressing drive. The roller is rotatably disposed at the bottom of the pressing frame and is used to abut against the blanket blank. The axis of the roller is parallel to the Y-axis.

[0016] By adopting the above technical solution, the abutment roller is rotatably set at the bottom of the lower pressure frame. When the abutment roller contacts the blanket blank and presses down, the abutment roller can rotate synchronously with the movement of the blanket blank, converting the sliding friction between the abutment roller and the blanket blank into rolling friction, which significantly reduces frictional damage to the surface of the blanket blank and protects the surface quality of the blanket blank.

[0017] Preferably, the longitudinal frame is also provided with a traction mechanism for guiding the blanket blank into the space between the upper and lower mounting frames. The traction mechanism includes a traction drive and a traction head. The traction head is located on the side of the first end pressing assembly away from the transverse frame. The traction drive is used to drive the traction head to slide along the X-axis. The traction head can pass between the upper and lower mounting frames and can grab the blanket blank.

[0018] By adopting the above technical solution, when the blanket blank is guided to the longitudinal frame, the traction drive drives the traction head to slide along the direction close to the transverse frame, so that the traction head passes between the two upper mounting frames and the two lower mounting frames and approaches the end of the blanket blank. After the traction head grabs the end of the blanket blank, the traction drive drives the traction head to slide along the direction away from the transverse frame, thereby smoothly pulling the blanket blank into the space between the upper mounting frames and the lower mounting frames. This solves the problem that the blanket blank itself may be difficult to enter the positioning mechanism on its own due to its softness and easy wrinkling, ensuring that the blanket blank accurately enters the positioning position and provides a reliable foundation for subsequent positioning and cutting.

[0019] Preferably, the cutting mechanism includes a cutter, a cutting table, and a cutting drive. The cutter and the cutting table are both located on the side of the end clamping assembly near the transverse frame. The cutter slides along the Z-axis on the longitudinal frame. The cutting table is fixed on the longitudinal frame and located below the cutter. The blanket blank can pass between the cutter and the cutting table. The cutting drive is used to drive the cutter to slide.

[0020] By adopting the above technical solution, the cutting table provides a supporting foundation for the blanket blank during cutting, preventing the blanket blank from sinking and deforming due to force during the cutting process; the cutting drive drives the cutter to slide down along the Z-axis, and works with the cutting table to cut the blanket blank that passes through, making the cutting method simple and efficient.

[0021] Preferably, the cutting table has a slit for the cutting blade to extend into.

[0022] By adopting the above technical solution, the cutter can extend into the slit during cutting. On the one hand, this ensures that the blanket blank is completely cut off, avoiding the presence of uncut fibers or edges due to contact between the cutter and the cutting table surface. On the other hand, the slit provides clearance for the cutter, reducing direct contact wear between the cutter and the cutting table, and extending the service life of both the cutter and the cutting table.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a transverse frame, a longitudinal frame, a blank table, guide rollers, a first sewing head, a positioning mechanism, a cutting mechanism, and a second sewing head, the sewing of both sides, cutting, and sewing of both ends of the blanket can be completed continuously and automatically on one machine. This significantly reduces the number of intermediate handling times of the blanket unit between the cutting and sewing processes, thereby effectively reducing time and manpower consumption, reducing production costs, and improving production efficiency. 2. By setting up a cutting area, waiting area, sewing area, first conveyor, second conveyor, third conveyor, and detector, the longitudinal frame is functionally divided and coordinated with the conveyor roller group to achieve orderly flow of the blanket unit. The detector can control the conveying rhythm according to the state of the sewing area, avoiding the lack of coordination between the blanket sewing process and the cutting process, which would cause process congestion or equipment idleness, and ensuring the continuity and efficiency of the sewing operation after cutting. 3. By setting up a head clamping assembly, an end clamping assembly, an upper mounting frame, a lower mounting frame, a clamping drive, a lower pressing drive, a lower pressing frame, a stop roller, a traction drive, and a traction head, the precise positioning and stable conveying of the blanket blank are achieved. The head clamping assembly and the end clamping assembly clamp and fix the blanket blank to ensure cutting accuracy. The lower pressing part and the stop roller determine the cutting length of the blanket blank. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a blanket-making machine. (Refer to...) Figure 1 The system includes a transverse frame 1 and a longitudinal frame 2. The length direction of the transverse frame 1 is parallel to the X-axis, and the length direction of the longitudinal frame 2 is parallel to the Y-axis. One end of the transverse frame 1 faces the side wall of the end of the longitudinal frame 2, and the bottom of the other end of the transverse frame 1 is provided with a blanking platform 11 for placing the blanket blank. Several guide rollers 12 are rotatably arranged on the transverse frame 1, and the guide rollers 12 guide the blanket blank from the blanking platform 11 towards the longitudinal frame 2. In this embodiment, the guide rollers 12 are driven by a motor. A set of first sewing heads 13 are symmetrically arranged on both sides of the transverse frame 1, and the first sewing heads 13 are used to sew the sides of the blanket blank.

[0031] Reference Figure 1 The longitudinal frame 2 is equipped with a positioning mechanism 3 and a cutting mechanism 4 at one end near the transverse frame 1. The positioning mechanism 3 is used to position the end of the blanket blank, and the cutting mechanism 4 is used to cut off the blanket blank positioned by the positioning mechanism 3. The cut-off blanket blank forms a blanket unit. A set of second sewing heads 231 are symmetrically arranged on both sides of the longitudinal frame 2. The second sewing heads 231 are used to sew the ends of the cut blanket unit.

[0032] Reference Figures 1 to 3 Specifically, the longitudinal frame 2 is divided into a cutting area 21, a waiting area 22, and a sewing area 23 along its length. The positioning mechanism 3 and the cutting mechanism 4 are both located in the cutting area 21, and the second sewing head 231 is located in the sewing area 23. The transverse frame 1 is located to the side of the longitudinal frame 2 beside the cutting area 21. A first conveyor 211 is installed in the cutting area 21, and a second conveyor 221 (using push rollers) is installed in the waiting area 22. A third conveyor 232 (also using push rollers) is installed in the sewing area 23. The first conveyor 211 conveys blanket units to the second conveyor 221, and the second conveyor 221 conveys blanket units to the third conveyor 232. The third conveyor 232 conveys the blanket units through the second sewing head 231 and finally delivers the finished blanket out of the longitudinal frame 2.

[0033] Reference Figure 3A detector 233 is installed in the seam edge area 23, and the detector 233 is electrically connected to the second conveyor 221 via a processor. The detector 233 monitors the working status of the seam edge area 23 in real time, that is, it monitors whether there are blanket units being sewn in the seam edge area 23. Based on this, the processor determines whether the seam edge area 23 is idle. If it is idle, it controls the second conveyor 221 to send the blanket units from the waiting area 22 into the seam edge area 23. In this embodiment, the detector 233 is a through-beam photoelectric sensor. The through-beam photoelectric sensor emits infrared light and detects whether the infrared light is blocked by the blanket units, thereby determining whether there are blanket units being sewn in the seam edge area 23.

[0034] To achieve reliable positioning of the blanket blank before cutting, refer to Figure 1 and Figure 2 The positioning mechanism 3 includes a front clamping assembly 31, a rear clamping assembly 32, a pressing part 36, and a pressing drive 37. The front clamping assembly 31 and the rear clamping assembly 32 are symmetrical on both sides of the longitudinal frame 2, with the front clamping assembly 31 located on the side of the longitudinal frame 2 away from the transverse frame 1. Both the front clamping assembly 31 and the rear clamping assembly 32 include an upper mounting bracket 33, a lower mounting bracket 34, and a clamping drive, with the upper mounting bracket 33 located above the lower mounting bracket 34.

[0035] Reference Figure 1 and Figure 2 The first conveying component 211 includes an upper conveying roller and a lower conveying roller. Several upper conveying rollers are rotatably mounted on the side wall of the upper mounting frame 33, and all upper conveying rollers are spaced apart along the Y-axis. Several lower conveying rollers are rotatably mounted on the side wall of the lower mounting frame 34, and all lower conveying rollers are spaced apart along the Y-axis. The axes of the upper and lower conveying rollers are parallel to the X-axis, and the upper and lower conveying rollers can jointly clamp the blanket blank. In this embodiment, all upper conveying rollers are driven by a single motor through the same chain drive structure, and all lower conveying rollers are driven by a single motor through the same chain drive structure. A clamping drive component moves the upper mounting frame 33 and the lower mounting frame 34 closer or further apart. In this embodiment, the lower mounting frame 34 is fixed to the longitudinal frame 2, and the upper mounting frame 33 is movably connected to the longitudinal frame 2 along the Z-axis. The clamping drive component uses an electric slide rail, and the upper mounting frame 33 is connected to the output end of the electric slide rail to move the upper mounting frame 33 closer or further away from the lower mounting frame 34.

[0036] Reference Figure 1 and Figure 2The pressing part 36 is higher than the upper mounting frame 33, and is located between the first end pressing assembly 31 and the last end pressing assembly 32 in the X-axis direction. The pressing drive 37 is used to drive the pressing part 36 to slide along the Z-axis direction. The pressing part 36 can abut against the upper surface of the blanket blank between the first end pressing assembly 31 and the last end pressing assembly 32 and press down. Specifically, the pressing part 36 adopts an electric push rod. The pressing part 36 includes a pressing frame 361 and an abutting roller 362. The pressing frame 361 is fixed to the output end of the pressing drive 37. The abutting roller 362 is rotatably disposed at the bottom of the pressing frame 361. The abutting roller 362 is used to abut against the blanket blank. The axis of the abutting roller 362 is parallel to the Y-axis, and the length of the abutting roller 362 is greater than the width of the blanket blank in the Y-axis direction.

[0037] To guide the end of the blanket blank smoothly into the space between the upper mounting bracket 33 and the lower mounting bracket 34 of the first end clamping assembly 31 and the end clamping assembly 32, refer to... Figure 1 and Figure 2 The longitudinal frame 2 is also provided with a traction mechanism 5 for guiding the blanket blank into the space between the upper mounting frame 33 and the lower mounting frame 34. The traction mechanism 5 includes a traction drive 51 and a traction head 52. The traction head 52 is located on the side of the first end clamping assembly 31 away from the transverse frame 1. The traction drive 51 is used to drive the traction head 52 to slide along the X-axis. The traction head 52 can pass between the upper mounting frame 33 and the lower mounting frame 34. The traction head 52 can grab the blanket blank. In this embodiment, the traction drive 51 is an electric push rod, and the traction head 52 can be an electric gripper installed at the output end of the electric push rod.

[0038] To achieve reliable cutting of the blanket blank, refer to Figure 1 and Figure 4 The cutting mechanism 4 includes a cutter 41, a cutting table 42, and a cutting drive. Both the cutter 41 and the cutting table 42 are located on the side of the end clamping assembly 32 near the transverse frame 1. The cutter 41 slides along the Z-axis on the longitudinal frame 2, and the cutting table 42 is fixed on the longitudinal frame 2 and located below the cutter 41. The cutting table 42 has a slit 421 for the cutter 41 to extend into, and the blanket blank can pass between the cutter 41 and the cutting table 42. The cutting drive is used to drive the cutter 41 to slide.

[0039] The implementation principle of a blanket machine according to an embodiment of this application is as follows: In use, the blanket blank is first placed on the blank table 11. Driven by the rotation of the guide roller 12, the blanket blank moves along the transverse frame 1 towards the longitudinal frame 2. During the movement, the first sewing heads 13 on both sides of the transverse frame 1 simultaneously sew the edges of the blanket blank on both sides in the Y-axis direction, completing the first edge sealing.

[0040] When the end of the blanket blank approaches the longitudinal frame 2, the traction drive 51 drives the traction head 52 to approach the transverse frame 1 along the X-axis. The traction head 52 passes between the upper mounting bracket 33 and the lower mounting bracket 34 of the first end clamping assembly 31, and between the upper mounting bracket 33 and the lower mounting bracket 34 of the end clamping assembly 32, and grips the end of the blanket blank. Subsequently, the traction head 52 slides in the opposite direction and returns to the side of the first end clamping assembly 31 away from the transverse frame 1. Afterward, the clamping drive of the first end clamping assembly 31 drives the upper mounting bracket 33 to move downward, and the upper and lower conveying rollers jointly clamp the first end of the blanket blank to complete the positioning. Next, the downward pressure drive 37 drives the abutment roller 362 of the downward pressure part 36 to move downward, pressing against the upper surface of the blanket blank between the first end clamping assembly 31 and the last end clamping assembly 32. Under the pressure, the blanket blank bends and further between the upper mounting bracket 33 and the lower mounting bracket 34 of the last end clamping assembly 32, increasing the length of the blanket blank between the first end clamping assembly 31 and the last end clamping assembly 32. Then, the clamping drive of the last end clamping assembly 32 drives the upper mounting bracket 33 to move downward, and the upper and lower conveying rollers together clamp the end of the blanket blank to be cut, completing the positioning of the required cutting length.

[0041] After positioning, the cutting mechanism 4 starts, and the cutting drive drives the cutter 41 to move downward along the Z-axis. The cutter 41 passes through the blanket blank and extends into the slit 421 of the cutting table 42, cutting off the positioned end of the blanket blank to form a blanket unit. After cutting, the cutter 41 resets, and the first conveyor 211 drives the blanket unit to move to the waiting area 22. The second conveyor 221 in the waiting area 22 temporarily stores the blanket unit, while the detector 233 in the sewing area 23 detects in real time whether a blanket unit is being sewn: if the sewing area 23 is empty, the second conveyor 221 drives the blanket unit into the sewing area 23. The third conveyor 232 drives the blanket unit to move, and the second sewing heads 231 on both sides of the longitudinal frame 2 simultaneously sew the two ends of the blanket unit in the X-axis direction. This reduces the number of handling operations during blanket processing, reduces time and labor costs, and reduces blanket production costs.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
