Description

Technical Field

[0001] The invention relates to quilt production equipment, in particular to thin quilt production equipment. Background Art

[0002] In daily life, quilt is a common household item, among which thin quilt (such as air-conditioning quilt) is one of many types of quilts. Thin quilt is mainly made of a layer of cotton material and two layers of cloth sewn together on four sides.

[0003] In the early days, thin quilts were mostly processed by manually controlling the corresponding equipment for separate step-by-step processing. This processing method not only employed a large number of workers, resulting in high labor costs, but also had low overall production efficiency.

[0004] With the advancement of science and technology, mechanical equipment is used to produce thin quilts. The specific production process is that the first sewing equipment is used to fix the cloth and cotton material, that is, the upper cloth, cotton material and lower cloth are transported to the first sewing equipment, and the middle parts of the upper cloth, cotton material and lower cloth are sewn by the first sewing equipment, so that the three layers of raw materials are fixed and form a semi-finished product. The semi-finished product is sewn separately by the horizontal sewing mechanism and the vertical sewing mechanism and then cut to obtain the finished thin quilt.

[0005] The fully automatic quilt sewing production line disclosed in CN112144179B discloses that: after the fabric grabbing assembly grabs the fabric from between two rollers, the fabric is placed on the lower pressing plate. Then, the downward pressure cylinder presses the upper pressing plate downward, pressing one end of the fabric between the upper and lower pressing plates. The two rollers continue to transport the fabric, so that the middle portion of the fabric accumulates between the rollers and the pressure standard transmission assembly. When the fabric length is determined, the fabric cutting mechanism cuts the fabric, and then the upper and lower pressing plates are released. The disadvantage of the above-mentioned fabric cutting mechanism is that since the fabric is cut by the motor-driven cold knife rotation, this method easily causes the fabric to have burrs during cutting, resulting in reduced product quality. Summary of the Invention

[0006] The invention provides a thin quilt production device, which can avoid burrs when cutting thin quilts.

[0007] The technical solutions to the above problems are as follows:

[0008] Thin quilt production equipment, including:

[0009] A horizontal edge sewing device for sewing the horizontal edges of a thin quilt;

[0010] For the longitudinal sewing device for sewing the longitudinal edges of the thin quilt, the longitudinal sewing device is located downstream of the transverse sewing device;

[0011] A cutting device for cutting the thin quilt after the horizontal and vertical edges are sewn together, the cutting device is located downstream of the vertical edge sewing device, and the cutting device includes a second frame and further includes:

[0012] a first clamping and conveying mechanism, the first clamping and conveying mechanism being fixed to the second frame;

[0013] a second clamping and conveying mechanism, the second clamping and conveying mechanism being fixed to the second frame and being located below the first clamping and conveying mechanism;

[0014] a hot cutting and trimming and sewing unit, the hot cutting and trimming and sewing unit being in sliding cooperation with the second frame;

[0015] A second driving mechanism drives the heat cutting and trimming and sewing unit to move laterally along the second frame, and the second driving mechanism is connected to the heat cutting and trimming and sewing unit.

[0016] When the present invention cuts the raw material by the hot cutting and trimming and sewing unit, the raw material is heated so that the trimming is sewn, thereby avoiding the occurrence of factors affecting product quality such as burrs on the trimming. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] After the raw material (for example, two layers of fabric and the middle cotton material between the two layers of fabric) passes through the cloth opening roller 2, it passes through the welding and sewing unit and the raw material traction unit, and the drive component 8 is started. Since the raw material is clamped by the upper pinch roller 6 and the lower pinch roller 7, the drive component 8 drives the lower pinch roller 7 to rotate to move the raw material. According to the program setting of the PLC, for example, when the raw material moves 2 meters, the first lifting and lowering driver 13 and the second lifting and lowering driver 19 work, the first lifting and lowering driver 13 drives the first punch head 14 to press down, and the second lifting and lowering driver 19 works. The second punch 20 is driven to press downward, and the raw material is pressed between the first punch 14 and the first ultrasonic welder 15, and the raw material is pressed between the second punch 20 and the second ultrasonic welder 21. The first ultrasonic welder 15 welds the raw material, and the second ultrasonic welder 21 welds the raw material. Therefore, the raw material between the first punch 14 and the first ultrasonic welder 15 is welded, and the raw material between the second punch 20 and the second ultrasonic welder 21 is welded, thereby forming two transverse suture lines.

[0056] Rotating the handwheel 24 drives the first connecting rod 23 to rotate, the first connecting rod 23 drives the first bevel gear 25 to rotate, the first bevel gear 25 drives the second bevel gear 26 to rotate, and the second bevel gear 26 drives the screw 27 to rotate. Since the screw 27 is threadedly connected to the first lower beam 10, and the first lower beam 10 is slidingly matched with the first frame 1, when the screw 27 rotates, it drives the first lower beam 10 to translate, thereby changing the distance between the first lower beam 10 and the second lower beam 16, and then changing the distance between the two suture lines.

[0068] The working process of the longitudinal edge sewing device B is as follows: after the raw material is sewn and output by the transverse edge sewing device A, the raw material passes through the first cloth roller 51, the second cloth roller 54, the first intermediate roller 53a, and the first cloth opening roller 32 in turn. When the raw material then passes between the wheel-shaped pressing die 37 and the ultrasonic welding component 38, the raw material is pressed between the wheel-shaped pressing die 37 and the ultrasonic welding component 38, so that under the action of the wheel-shaped pressing die 37 and the ultrasonic welding component, the raw material is sewn. The sewn raw material then passes between the middle upper pinching roller 47 and the middle lower pinching roller 48, and then the raw material passes through the third cloth roller 60, the fourth cloth roller 61, the second intermediate roller 64, the fifth cloth roller 64a, the third intermediate roller 65, and the sixth cloth roller 64b in turn, and is finally output from the sixth cloth roller 64b. During this process, the raw material is respectively caught by the first intermediate roller 53a, the second intermediate roller 64, and the third intermediate roller 65.

[0069] The horizontal edge sewing device of the thin quilt has a first clamping speed for the thin quilt, and the longitudinal edge sewing device of the thin quilt in the present invention has a second clamping speed for the thin quilt. At the beginning, under the control of the PLC controller (the PLC controller is a well-known electrical control unit, not shown in the figure), the first clamping speed is greater than the second clamping speed, so that more raw materials are left on the feed side of the longitudinal sewing device. Since the raw materials are wrapped around the first intermediate roller 53a, under the action of the gravity of the first intermediate roller 53a, the first intermediate roller 53a carries the first slide 53 downward along the first guide rod 52, so that more raw materials are stored. When the first photoelectric sensor 57c detects the first intermediate roller 53a, it means that the set storage limit has been reached at this time. The first photoelectric sensor 57c feeds back the detected signal to the PLC controller The device controls the first pinching speed to be less than the second pinching speed, and the PLC controller controls the first pinching speed to be less than the second pinching speed. With the continuous conveying of the raw material in the longitudinal sewing device, the raw material stored in the first cloth storage unit is reduced. The upper middle pinching roller 47 and the lower middle pinching roller 48 exert forces on the raw material, and the raw material exerts a pulling force on the first intermediate roller 53a, so that the first intermediate roller 53a and the first slide 53 move upward along the first guide rod 52. When the first photoelectric sensor 57b detects the first intermediate roller 53a, it indicates that the first pinching speed for controlling the feeding can no longer meet the requirement of the second pinching speed. The PLC controller controls the first pinching speed to be greater than the second pinching speed. Through the above process, the first intermediate roller 53a switches between the first photoelectric sensor 57b and the first photoelectric sensor 57c.

[0070] Since a thin quilt cutting device C is provided downstream of the thin quilt longitudinal edge sewing device, and the thin quilt cutting device C has a raw material clamping unit for the thin quilt, and the raw material clamping unit temporarily transports the raw material when the thin quilt cutting device cuts the thin quilt, therefore, for the raw material output from the longitudinal sewing device, since the raw material is clamped by the second intermediate roller 64 and the third intermediate roller 65, the raw material is stored by the same principle as above.

[0071] like Figure 1 、 Figures 15 to 19 The cutting device C cuts the thin quilt after the horizontal and vertical edges are sewn together. The cutting device C is located downstream of the longitudinal edge sewing device B.

[0074] The hot cutting and trimming and sewing unit C4 includes a first support 76, a first ultrasonic assembly 77, a second support 78, a linear actuator 79, and a cutter assembly.

The cutter assembly cooperates with the first ultrasonic assembly 77 to heat-cut the thin quilt and sew the cut edges.

[0078] The cutter assembly includes a cutter bracket 80, a cutter die 81, a first bevel gear 82, a second bevel gear 83, a first transmission shaft 84, a first transmission gear 85, and a first rack (not shown in the figure). The cutter bracket 80 is U-shaped, and the cutter bracket 80 is connected to the output end of the linear drive 79. The cutter die 81 is movably connected to the cutter bracket 80.

The fixed shaft 81b is movably connected to the cutter bracket 80 through a bearing. The first bevel gear 82 is fixed to the fixed shaft 81b. The first cutter 81c and the pressure tooth 81d are both arranged on the circumferential surface of the wheel-shaped component 81a, and pressure teeth 81d are arranged on both sides of the first cutter 81c.

[0079] The second bevel gear 83 is meshed with the first bevel gear 82, the second bevel gear 83 is fixed to one end of the first transmission shaft 84, the other end of the first transmission shaft 84 is fixed to the first transmission gear 85, the second support 78 is provided with a clearance hole 78a, the first transmission gear 85 cooperates with the clearance hole 78a, the first rack is fixed to the second frame C1, the first rack is located between the two second sliders 78b, and the first rack is meshed with the first transmission gear 85.

[0080] The hot cutting and trimming and sewing unit C4 also includes a cold cutting component, which includes a first driver 86, a knife holder 87, a central axis 88, a first drive motor 89, a third transmission mechanism 90, a second cutter 91, and a third cutter 92.

[0081] The working process of the cutting device C is as follows:

[0082] The raw material output from the longitudinal edge sewing device B passes through the cloth guide roller 70 and passes through the first clamping mechanism C2, the cutter assembly, and the second clamping mechanism C3 from top to bottom. At this time, the cutter assembly separates the quilt and is in a separated state, while the first clamping mechanism C2 and the second clamping mechanism C3 clamp the quilt. The force generated by the first clamping mechanism C2 and the second clamping mechanism C3 when working causes the quilt to move from bottom to bottom. When it moves between the two transverse sewing lines, the middle part between the two transverse sewing lines corresponds to the cutter assembly. The first clamping mechanism C2 and the second clamping mechanism C3 stop working, and then the linear drive 79 works. The linear drive 79 drives the cutter bracket 80 to move linearly with the cutting die 81, pushing the cutting die 81 to press the quilt onto the first ultrasonic assembly 77. Since the part of the quilt between the first clamping mechanism C2 and the second clamping mechanism C3 is in a tensioned state,

[0083] At this time, the second driving mechanism C5 is working, and the second driving mechanism C5 drives the first shaft 95 to rotate. The first shaft 95 drives the third transmission mechanism 97 and the fourth transmission mechanism 98 to work, so that the belts in the third transmission mechanism 97 and the fourth transmission mechanism 98 move, and the belt in the third transmission mechanism 97 moves the first support 76, and the belt in the fourth transmission mechanism 98 moves the second support 78. When the second support 78 moves, the first transmission gear 85 rotates through the meshing action of the first transmission gear 85 and the first rack. The power generated by the first transmission gear 85 is transmitted to the cutting die 81 through the first transmission shaft 84, the second bevel gear 83, and the first bevel gear 82, so that the cutting die 81 rotates. The cutting die 81 cuts the thin quilt, and the cut edges are welded under the action of the heat generated by the pressing teeth 81d and the first ultrasonic component 77, so that the cut edges are sewed. Since the cutting die 81 does not cut the thin quilt, the cold cutting assembly moves with the first support 76 when the first support 76 moves, and the knife holder 87 is driven by the first driver 86, so that the second cutter 91 or the third cutter 92 acts on the thin quilt, cutting the thin quilt that has been hot-cut.
