[0026] This utility model discloses a ribbon sewing machine, comprising a frame 1, a sewing machine head mounted on the frame 1, and a feeding device. The feeding device includes a feeding mechanism for inputting multiple ribbon segments, a bevel cutting mechanism for cutting the ribbon segments at an angle, and a feeding conveyor mechanism for gripping and conveying the output ribbon segments to the sewing area. A feeding correction mechanism for adjusting the position of the output ribbon segments is provided between the bevel cutting mechanism and the feeding conveyor mechanism. The sewing machine head includes a presser foot mechanism for secondary correction of the ribbon segments placed on a template.

[0027] The material feeding and conveying mechanism includes a feeding mounting base 3 mounted on the linear module 2, which is movable between the material feeding position and the sewing position. A first mounting base 4 is slidably mounted on the feeding mounting base 3, and a first motor 4a is mounted on the feeding mounting base 3 to drive the first mounting base 4 to slide back and forth. A material feeding mounting base 5 is slidably mounted on the first mounting base 4, and a first drive cylinder 6 is mounted on the first mounting base 4 to drive the material feeding mounting base 5 to slide back and forth. Three sets of material feeding devices are spaced apart on the material feeding mounting base 5.

[0028] A first mounting base 4 is slidably connected to a second mounting base 7. The second mounting base 7 is equipped with a first lifting cylinder 8 that drives the first mounting base 4 to move up and down. A first motor 4a is connected to the second mounting base 7 via a linear transmission assembly, which includes a first gear 9, a second gear 10, and a lead screw 11. The lead screw 11 is rotatably mounted on a feeding mounting base 3. The drive shaft of the first motor 4a has the first gear 9, and one end of the lead screw 11 has a second gear 10 that meshes with the first gear 9.

Compared to cylinder drive, motor drive offers more stable speed and allows for more flexible movement control. It can start and stop at any position, facilitating adjustment of the movement distance.

[0029] The material gripping device includes a first clamping plate 12 and a second clamping plate 13. Each set of material gripping devices is equipped with an independently driven material gripping cylinder 14. The material gripping cylinder 14 drives the first clamping plate 12 to move in coordination with the second clamping plate 13 to grip the material. The material gripping mounting base 5 is equipped with multiple sets of secondary drive cylinders 15 for driving the corresponding material gripping devices to move back and forth twice.

[0030] Two connection schemes are provided based on the desired shape of the decorative strip: The first scheme is for multiple strip segments whose length decreases sequentially from left to right. The middle gripping device is connected to one or more sets of secondary drive cylinders 15, the right-side gripping device is connected to one or more sets of secondary drive cylinders 15, and the left side does not require a secondary drive cylinder 15 connection. The second scheme is for multiple strip segments whose length increases sequentially from left to right. The middle gripping device is connected to one or more sets of secondary drive cylinders 15, the left-side gripping device is connected to one or more sets of secondary drive cylinders 15, and the right side does not require a secondary drive cylinder 15 connection.

[0031] Three sets of gripping devices clamp one end of the corresponding output strip segment. The three sets of gripping devices are arranged into the required shape by the corresponding secondary drive cylinders 15, and then the other end of the strip segment is cut off by a bevel cutter. Subsequently, the gripping devices move the strip segment above the feeding correction mechanism, the gripping devices release the corresponding strip segment, and the feeding correction mechanism corrects the position of the strip segment.

[0032] A material support plate 16 is slidably provided below the material gripping mounting base 5, and a material support drive cylinder 17 is provided on one side of the material gripping mounting base 5 to drive the material support plate 16 to slide back and forth. After the calibration is completed, the material gripping device clamps the corresponding decorative strip segment, and the linear module 2 moves the decorative strip segment to the sewing position.

[0033] A feeding correction mechanism is located between the oblique cutting mechanism and the material gripping and conveying mechanism. The feeding correction mechanism includes a first correction plate 18 and a second correction plate 19.

The first connecting plate 21 is slidably mounted on a second lifting cylinder mounting plate 22, and the end of the second lifting cylinder mounting plate 22 is fixed to the frame 1.

[0034] Each first stop bar 18a forms a channel between itself and the corresponding second stop bar 19a for the decorative strip to pass through. The right end of the first correction plate 18 has a first abutting part 18b that cooperates with the inner side of the rightmost second stop bar 19a, and the left end of the second correction plate 19 has a second abutting part 19b that cooperates with the inner side of the leftmost first stop bar 18a.

[0035] In the initial state, the first correction plate 18 and the second correction plate 19 are located at opposite ends of the first mounting base plate 20. There is a gap between the first abutment part 18b and the rightmost second stop bar 19a, and a gap between the second abutment part 19b and the leftmost first stop bar 18a, allowing the trim section to be inserted into the channel. Subsequently, the first correction plate 18 and the second correction plate 19 move towards the center until the first abutment part 18b abuts against the rightmost second stop bar 19a and the second abutment part 19b abuts against the leftmost first stop bar 18a, after which they stop moving. The first stop bar 18a and the corresponding second stop bar 19a cooperate to correct the position of the trim section in the channel.

The second calibration cylinder 28 can drive the second calibration base plate 24 to move horizontally, thereby driving the second stop bar 19a on the second calibration plate 19 to move horizontally.

[0038] The second lifting cylinder mounting plate 22 is equipped with a second lifting cylinder 29. The drive rod of the second lifting cylinder 29 is connected to the first mounting base plate 20.

The drive rods of the first positioning cylinder 38 and the second positioning cylinder 39 are respectively connected to the positioning plate 36.

[0043] All three methods described above can adjust the width of the first movable groove 37 by sliding the first positioning plate 36 relative to the rightmost side of the first pressure frame 35 through the first positioning cylinder 38 and the second positioning cylinder 39. The positioning plate 36 moves the decorative ribbon segment to achieve the correction function and improve the sewing quality.
