Description

Technical Field

[0001] The invention belongs to the technical field of quilting machine feeding, in particular to a feeding device for a double-head quilting machine. Background Art

[0002] The double-head quilting machine is a mechanical equipment specially used for quilting processing. It is widely used in textile, clothing, household goods and other fields. The double-head quilting machine is equipped with two sewing needle assemblies, which can quilt two seams at the same time, and can move longitudinally, transversely and vertically. It can not only adapt to different fabric pattern requirements, but also improve production efficiency.

[0003] The patent with announcement number CN219908060U discloses a computer quilting machine feeding assembly, including a computer quilting machine tool and a quilting machine feeding assembly. The quilting machine feeding assembly consists of a feeding bed, multiple groups of clips, and four groups of corner fixing components. The feeding bed is movably plugged into the computer quilting machine tool, multiple groups of clips are symmetrically arranged on the feeding bed, and four groups of corner fixing components are respectively arranged on the four corners of the feeding bed. This scheme uses multiple groups of clips to fix and tension the corners of the textile so that the entire fabric of the textile is evenly stressed, preventing skewness during the quilting process. The raised teeth arranged on the splint make the textile more firmly fixed, which not only prevents the textile from falling off, but also has a better tensioning effect on the textile.

[0004] In the above scheme, when sewing textiles, only one group of textiles can be placed on the feeding bed at a time. Therefore, after the textiles are sewn, the sewn textiles must be taken down from the feeding bed before the next group of textiles can be placed on the feeding bed for sewing. In this process, a lot of time is wasted in taking and placing the textiles, and continuous sewing of the textiles cannot be achieved, resulting in low textile sewing efficiency. For this reason, the present invention provides a feeding device for a double-head quilting machine. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a feeding device of a double-head quilting machine described in the present invention comprises a machine tool and two groups of chains, two groups of transmission shafts are rotatably installed in the machine tool, two groups of sprockets are installed on the transmission shafts, each group of chains meshes with two groups of sprockets, and a plurality of groups of unloading plate assemblies are arranged around the two groups of chains, a sewing frame is movably installed on the machine tool, the unloading plate assembly comprises a plate body, the bottom of the plate body is fixedly connected to the chain, four groups of supporting shafts are respectively arranged on the four sides of the plate body, a plurality of groups of supporting seats are rotatably sleeved on the supporting shaft, the supporting seat is fixedly installed on the edge of the plate body, an articulated seat is arranged in the supporting seat, the articulated seat is rotatably connected to the supporting shaft, a clamping plate fixedly connected to the articulated seat, and torsion springs are arranged on both sides of the articulated seat, one end of the torsion spring is fixedly connected to the articulated seat, and the other end of the torsion spring is fixedly connected to the supporting seat;

[0007] Through the transmission shaft, sprocket and chain, several groups of feeding plate assemblies are made to move in a circular motion, so that several groups of feeding plate assemblies can pass under the sewing frame in turn, thereby realizing continuous sewing of textiles, and in the same time period, the taking, placing and sewing of textiles can be carried out simultaneously, thereby improving the sewing efficiency of textiles.

[0008] Preferably, two groups of limiting mechanisms are symmetrically arranged on the hinge seat, the limiting mechanism comprises a fixing sleeve, the fixing sleeve is fixedly mounted on the hinge seat, a bayonet of the fixing sleeve movably plugged into, a guide column fixedly connected to the bayonet pin, a spring sleeved on the guide column, the spring is located in the fixing sleeve, the guide column is plugged into the fixing sleeve, and two groups of positioning components are symmetrically arranged on the support seat, the positioning component comprises a fixing block for limiting the positioning bayonet pin, the fixing block is fixedly mounted on the support seat, the arc plate is movably mounted on the support seat, two groups of arc grooves are symmetrically opened on the support seat, the arc plate is slidably connected to the arc groove, an arc hole is opened on one side of the arc groove, four groups of rollers are rotatably installed on one side of the lower end of the arc plate, the rollers are rotatably connected to the arc hole, a first inverted inclined surface is arranged on the other end of the bayonet pin, and a second inverted inclined surface is arranged on one end of the arc plate;

[0009] Since one end of the clamping plate can be limited after being tilted, it is convenient for workers to smooth the edge of the textile, thereby improving the workers' efficiency in smoothing the textile.

[0010] Preferably, a ratchet mechanism is arranged in the hinge seat, the ratchet mechanism comprises a ratchet ring, the ratchet ring is fixedly installed in the hinge seat, a fixing ring is arranged in the ratchet ring, the fixing ring is fixedly sleeved on the support shaft, three groups of ratchet pawls are hinged around the outer ring of the fixing ring, a U-shaped spring bar is arranged on one side of the ratchet pawl, a plurality of groups of slots are opened on the inner ring of the ratchet ring, the end of the ratchet pawl is clamped in the slot, and a knob is arranged at one end of the support shaft;

[0011] Turning the knob rotates the support shaft, and the support shaft drives several groups of fixed rings to rotate together. Due to the rebound force of the U-shaped elastic bar, the pawl presses against the slot, and the rotating fixed ring drives the ratchet ring to rotate through the pawl, and the ratchet ring drives the corresponding hinged seat to rotate together with the splint. Similarly, the other three groups of knobs are turned according to the same operation, so as to realize the above-mentioned pressing up of all the splints. The operation is simple and fast, which improves the efficiency of sewing textiles.

[0012] Preferably, six groups of jacks are provided on the knob;

[0013] Specifically, when the knob is turned, a set of extension rods can be inserted into one of the six groups of sockets, and then the extension rods are turned, the extension rods will drive the knob to rotate, thereby achieving the above-mentioned pressing of the splint.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. Through the transmission shaft, sprocket and chain, several groups of feeding plate assemblies are made to move in a circular motion, so that several groups of feeding plate assemblies can pass under the sewing frame in turn, thereby realizing continuous sewing of textiles, and in the same time period, the taking, placing and sewing of textiles can be carried out simultaneously, thereby improving the sewing efficiency of textiles.

[0016] 2. Under the action of the rebound force of the spring, the end of the pin is stuck between the fixed block and the curved plate, so that the splint cannot rotate. Similarly, the same operation is performed on the remaining splints. After smoothing the four sets of edges of the textile, continue to press the splint, and the first inverted slope at the end of the pin will slide against the second inverted slope. At the same time, the pin and the guide column move back to the direction of the curved plate until the first inverted slope is offset from the second inverted slope. Under the action of the rebound force of the spring, the end of the pin is close to the curved plate. At this time, the splint is released, and the end of the pin drives the curved plate to slide back through the extrusion force until the curved plate is blocked by the end of the arc groove and cannot move. The end of the pin will automatically offset the curved plate, thereby releasing the limit on the pin and realizing that the splint presses the edge of the textile. Since one end of the splint can be limited after being tilted, it is convenient for the staff to smooth the edge of the textile, thereby improving the staff's smoothing efficiency.

[0017] 3. When the splint needs to be pressed down, the knob is turned to rotate the support shaft, and the support shaft drives several groups of fixed rings to rotate together. Due to the rebound force of the U-shaped elastic bar, the pawl is pressed against the slot, and the rotating fixed ring drives the ratchet ring to rotate through the pawl, and the ratchet ring drives the corresponding hinged seat to rotate together with the splint. Similarly, the remaining three groups of knobs are turned according to the same operation to achieve the above-mentioned pressing up of all splints. The operation is simple and fast, which improves the efficiency of sewing textiles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figures 1 to 4 As shown, a feeding device of a double-head quilting machine described in an embodiment of the present invention includes a machine tool 1 and two groups of chains 4. Two groups of transmission shafts 2 are rotatably installed in the machine tool 1, and two groups of sprocket wheels 3 are installed on the transmission shafts 2. Each group of chains 4 meshes with two groups of sprocket wheels 3. A plurality of groups of unloading plate assemblies 5 are arranged around the two groups of chains 4. A sewing frame 6 is movably installed on the machine tool 1. The unloading plate assembly 5 includes a plate body 501, the bottom of the plate body 501 is fixedly connected to the chain 4, and four sides of the plate body 501 are respectively provided with A support shaft 502 is formed, and the support shaft 502 is rotatably mounted with a plurality of support seats 503. The support seats 503 are fixedly mounted on the edge of the plate body 501. A hinge seat 504 is arranged inside the support seat 503. The hinge seat 504 is rotatably connected to the support shaft 502, and a clamping plate 505 is fixedly connected to the hinge seat 504. Torsion springs 506 are arranged on both sides of the hinge seat 504, and one end of the torsion spring 506 is fixedly connected to the hinge seat 504, and the other end of the torsion spring 506 is fixedly connected to the support seat 503.

[0032] Specifically, two sets of sewing needle assemblies can be installed on the sewing frame 6. When the textile needs to be sewn, the textile is placed on the unloading plate assembly 5 located at the feeding point. Figure 1 The middle arrow indicates the position, and then the textile placed on the plate body 501 is arranged and smoothed, and then the splint 505 is pressed, and the splint 505 rotates together with the hinge seat 504, so that the splint 505 is tilted toward one end of the textile, and the hinge seat 504 screws two sets of torsion springs 506, and then the edge of the textile is placed under one end of the splint 505, and the edge of the textile is smoothed, and then the pressure on the splint 505 is released, and under the action of the counter-torque force of the torsion spring 506, the splint 505 is rotated back, and one end of the splint 505 presses the edge of the textile, and similarly, the same operation is performed on the remaining splints 505, so that the four sides of the textile are pressed by the splint 505, thereby realizing the placement of the textile, and then a group of transmission shafts 2 are driven to rotate by a motor, and the group of transmission shafts 2 drives two groups of sprockets 3 to rotate, and the sprockets 3 drive the chains 4 together with several groups of discharge plate assemblies 5 to make circular motions, and the attached Figure 2The direction indicated by the middle arrow is the circular motion direction, until the feed plate assembly 5 with the textile placed thereon moves to the bottom of the sewing frame 6, and then the movement of the feed plate assembly 5 is paused. During the process of sewing the textiles by the two groups of sewing needle assemblies on the sewing frame 6, the staff can place the textiles to be sewn on the next group of feed plate assembly 5. When the textiles are sewn, the next group of textiles is moved to the bottom of the sewing frame 6. During the process of sewing the next group of textiles, the staff can not only place the textiles, but also remove the sewn textiles from the corresponding feed plate assembly 5, and repeat the above operation in a cycle. Compared with the prior art, several groups of feed plate assemblies 5 are made to move in a circular motion through the transmission shaft 2, the sprocket 3, and the chain 4, so that several groups of feed plate assemblies 5 can pass under the sewing frame 6 in turn, thereby realizing continuous sewing of the textiles, and in the same time period, the taking and placing of textiles and sewing can be carried out simultaneously, thereby improving the sewing efficiency of the textiles.

[0033] like Figures 5 to 7 As shown, two groups of limiting mechanisms 507 are symmetrically arranged on the hinge seat 504, and the limiting mechanism 507 includes a fixing sleeve 5071, the fixing sleeve 5071 is fixedly installed on the hinge seat 504, a bayonet 5072 that is movably plugged into the fixing sleeve 5071, a guide column 5073 that is fixedly connected to the bayonet 5072, a spring 5074 that is sleeved on the guide column 5073, the spring 5074 is located in the fixing sleeve 5071, and the guide column 5073 is plugged into the fixing sleeve 5071. Two groups of positioning components 508 are symmetrically arranged on the support seat 503, and the positioning component 508 includes a fixing member for limiting the positioning bayonet 5072. Block 5081, the fixed block 5081 is fixedly installed on the support seat 503, the arc plate 5082 is movably installed on the support seat 503, two groups of arc grooves 5031 are symmetrically opened on the support seat 503, the arc plate 5082 is slidably connected to the arc groove 5031, one side of the arc groove 5031 is opened with an arc hole 50321, four groups of rollers 5083 are rotatably installed on one side of the lower end of the arc plate 5082, the rollers 5083 are rotatably connected to the arc hole 50321, the other end of the pin 5072 is provided with a first inverted slope 721, and one end of the arc plate 5082 is provided with a second inverted slope 821.

[0034] Specifically, before one end of the clamping plate 505 presses the edge of the textile, the staff needs to tidy up the edge of the textile to ensure that the edge of the textile is smoothed. During this process, the staff needs to keep pressing the clamping plate 505, which not only makes the staff more laborious, but also makes the staff only have one hand to smooth the edge of the textile, which increases the difficulty of the staff to smooth the edge of the textile, resulting in a decrease in the efficiency of the staff to smooth the edge of the textile. In the initial state, one end of the arc-shaped plate 5082 with the second inverted bevel 821 is flush with one side of the fixed block 5081, so when pressing During the clamping process of the plate 505, the plate 505 drives the limiting mechanism 507 to rotate together. As the limiting mechanism 507 rotates, the first inverted slope 721 at the end of the latch 5072 on the limiting mechanism 507 will be squeezed by one side of the fixed block 5081, so that the latch 5072 and the guide column 5073 move away from the fixed block 5081, and the latch 5072 compresses the spring 5074. At the same time, the first inverted slope 721 pushes the second inverted slope 821, so that the arc plate 5082 retreats along the arc groove 5031, and the arc plate 5082 drives the four groups of rollers 5083 to move along the arc hole 5031. 21 until the end of the latch 5072 is stuck between the fixed block 5081 and the curved plate 5082 under the rebound force of the spring 5074, so that the clamping plate 505 cannot rotate. Similarly, the same operation is performed on the remaining clamping plates 505. After the four groups of edges of the textile are smoothed, the clamping plate 505 is pressed continuously, and the first inverted slope 721 at the end of the latch 5072 will slide against the second inverted slope 821. At the same time, the latch 5072 and the guide column 5073 move away from the curved plate 5082 until the first inverted slope 721 is offset from the second inverted slope 821. The end of the latch 5072 will automatically be offset from the arc plate 5082, thereby releasing the limit on the latch 5072 and enabling the splint 505 to press the edge of the textile. Since one end of the splint 505 can be limited after being tilted up, it is convenient for the staff to smooth the edge of the textile, thereby improving the staff's efficiency in smoothing the textile.

[0035] Embodiment 2

[0036] like Figure 8 and Fig. 9As shown, compared with Example 1, another embodiment of the present invention is: a ratchet mechanism 509 is arranged in the hinge seat 504, the ratchet mechanism 509 includes a ratchet ring 5091, the ratchet ring 5091 is fixedly installed in the hinge seat 504, a fixing ring 5092 is arranged in the ratchet ring 5091, the fixing ring 5092 is fixedly sleeved on the support shaft 502, three groups of pawls 5093 are hinged around the outer ring of the fixing ring 5092, a U-shaped elastic strip 5094 is arranged on one side of the pawl 5093, a plurality of groups of slots 5095 are opened on the inner ring of the ratchet ring 5091, the end of the pawl 5093 is engaged with the slot 5095, and a knob 5021 is arranged at one end of the support shaft 502.

[0037] Specifically, in the process of placing the textile on the feeding plate assembly 5, the staff needs to press up the clamping plates 505 one by one, and then put down the clamping plates 505. Similarly, in the process of removing the sewn textile from the feeding plate assembly 5, the above operation needs to be repeated. This operation is time-consuming and labor-intensive, thereby affecting the efficiency of sewing the textile. Therefore, when the clamping plates 505 need to be pressed down, the knob 5021 is screwed to rotate the support shaft 502, and the support shaft 502 drives the plurality of fixed rings 5 092 rotates together, due to the rebound force of the U-shaped spring bar 5094, the pawl 5093 presses against the card slot 5095, the rotating fixing ring 5092 drives the ratchet ring 5091 to rotate through the pawl 5093, and the ratchet ring 5091 drives the corresponding hinge seat 504 to rotate together with the clamping plate 505. Similarly, the remaining three sets of knobs 5021 are screwed in the same way, so as to realize the above-mentioned pressing up of all the clamping plates 505. The operation is simple and fast, which improves the efficiency of sewing textiles. When the textiles are laid flat on After the material discharging plate assembly 5 is put on, after confirming that the edge of the textile under a set of clamping plates 505 is flat, continue to press the clamping plates 505, and under the cooperation of the limiting mechanism 507 and the clamping assembly 508, the clamping plates 505 rotate back together with the hinge seat 504, so that one end of the clamping plates 505 presses the edge of the textile, and at the same time the hinge seat 504 drives the corresponding ratchet ring 5091 to rotate back, and the ratchet ring 5091 drives the fixing ring 5092 to rotate back together with the support shaft 502 through the ratchet pawl 5093, and the rotation The support shaft 502 drives the remaining fixed rings 5092 to rotate back together, but the remaining fixed rings 5092 drive the corresponding pawls 5093 to be unable to resist the corresponding slots 5095, so that the remaining ratchet rings 5091 together with the clamping plates 505 cannot rotate. Therefore, when operating one set of clamping plates 505 to press the edge of the textile, it will not affect the adjacent clamping plates 505, so that the staff can press down the edge of the textile with the clamping plates 505 after confirming that the edges of the textile are flat one by one.

[0038] Furthermore, six groups of jacks 5022 are provided on the knob 5021 .

[0039] Specifically, when the knob 5021 is turned, a set of extension rods can be inserted into one of the six sets of sockets 5022, and then the extension rods can be turned, which will drive the knob 5021 to rotate, thereby achieving the above-mentioned pressing of the splint 505. The cooperation between the extension rods and the sockets 5022 makes it easier and faster for the staff to press up the splint 505.

[0040] Working principle: Place the textile on the discharge plate assembly 5 located at the loading point, then arrange and smooth the textile placed on the plate body 501, and then press the splint 505, the splint 505 rotates together with the hinge seat 504, so that the splint 505 is tilted toward one end of the textile, and the hinge seat 504 screws two sets of torsion springs 506, then place the edge of the textile under one end of the splint 505, and smooth the edge of the textile, and then release the pressure on the splint 505, under the action of the counter-torque force of the torsion spring 506, the splint 505 rotates back, and one end of the splint 505 presses the edge of the textile, and similarly, perform the same operation on the remaining splints 505, so that the four sides of the textile are pressed by the splints 505, thereby achieving the textile Place, then drive a group of transmission shafts 2 to rotate through a motor, the group of transmission shafts 2 drives two groups of sprocket wheels 3 to rotate, the sprocket wheels 3 drive the chains 4 together with several groups of feeding plate assemblies 5 to make circular motion, until the feeding plate assembly 5 with the textile placed thereon moves to the bottom of the sewing frame 6, then stop the movement of the feeding plate assembly 5, while the two groups of sewing needle assemblies on the sewing frame 6 are sewing the textiles, the staff can place the textiles to be sewn on the next group of feeding plate assemblies 5, when the textiles are sewn, the next group of textiles is moved under the sewing frame 6, during the sewing process of the next group of textiles, the staff can not only place the textiles, but also remove the sewn textiles from the corresponding feeding plate assembly 5, and repeat the above operation in a cycle;

[0041] When the clamping plate 505 is pressed, the clamping plate 505 drives the limiting mechanism 507 to rotate together. As the limiting mechanism 507 rotates, the first inverted slope 721 at the end of the pin 5072 on the limiting mechanism 507 will be squeezed by one side of the fixed block 5081, so that the pin 5072 and the guide column 5073 move back to the fixed block 5081, and the pin 5072 compresses the spring 5074. At the same time, the first inverted slope 721 pushes the second inverted slope 821, so that the arc plate 5082 retreats along the arc groove 5031, and the arc plate 5082 drives the four groups of rollers 5083 to roll along the arc hole 50321 until the end of the pin 5072 is stuck between the fixed block 5081 and the arc plate 5082 under the rebound force of the spring 5074, so that the clamping plate 505 cannot rotate. Similarly, the rest of the clamping plates The same operation is performed on the plate 505. After the four groups of edges of the textile are smoothed, the clamping plate 505 is continuously pressed, and the first inverted slope 721 at the end of the latch 5072 will slide against the second inverted slope 821. At the same time, the latch 5072 and the guide column 5073 move away from the arc plate 5082 until the first inverted slope 721 is offset from the second inverted slope 821. Under the rebound force of the spring 5074, the end of the latch 5072 is in close contact with the arc plate 5082. At this time, the clamping plate 505 is released, and the end of the latch 5072 drives the arc plate 5082 to slide back through the extrusion force until the arc plate 5082 is blocked by the end of the arc groove 5031 and cannot move. The end of the latch 5072 will automatically offset the arc plate 5082, thereby releasing the limit on the latch 5072, so that the clamping plate 505 can press the edge of the textile.

[0042] When it is necessary to press down the splint 505, the knob 5021 is turned to rotate the support shaft 502, and the support shaft 502 drives several groups of fixing rings 5092 to rotate together. Due to the rebound force of the U-shaped elastic bar 5094, the pawl 5093 is pressed against the slot 5095, and the rotating fixing ring 5092 drives the ratchet ring 5091 to rotate through the pawl 5093, and the ratchet ring 5091 drives the corresponding hinge seat 504 to rotate together with the splint 505. Similarly, the remaining three groups of knobs 5021 are turned according to the same operation to achieve the above-mentioned pressing up of all the splints 505.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
