[0001] This utility model belongs to the field of garment sewing processing technology, specifically a drag plate positioning mechanism for a bag opening sewing machine. Background Technology

[0002] Patent No. 202420397091.6 discloses a bag opening sewing machine, including a frame. The frame is equipped with a bag folding mechanism, a material feeding mechanism, a cloth dragging mechanism, a material feeding positioning mechanism, a laser device, and a sewing mechanism. The material feeding mechanism is located between the bag folding mechanism and the sewing mechanism. The material feeding positioning mechanism is located below the bag folding mechanism and includes a material feeding mounting seat fixed on the frame. The material feeding mounting seat is located below the bag folding mechanism of the bag opening sewing machine. The material feeding mounting seat is provided with a suction positioning plate that can slide back and forth. The suction positioning plate is provided with a positioning groove that is consistent with the cutting direction of the bag opening. A positioning piece that can be raised and lowered is provided in the positioning groove.

[0003] The bag sewing machine disclosed in this patent requires the bag lip and the secondary sewing base material to be placed sequentially into a template above the suction positioning plate according to the processing order. However, a defect exists in this placement process: the template may detach from its initially set position, preventing the dragging mechanism from moving the template and affecting the normal operation of subsequent processes. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a cloth plate positioning mechanism for a bag opening sewing machine. This mechanism can lock and fix the cloth plate located at the feeding positioning mechanism, preventing misalignment of the cloth plate and ensuring the normal operation of subsequent processes.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a positioning mechanism for a cloth plate of a bag sewing machine, including a positioning mounting base plate, a positioning mounting top plate that can be raised and lowered above the positioning mounting base plate, a first lifting cylinder for driving the positioning mounting top plate to move up and down; positioning clamps are respectively provided at both ends of the positioning mounting top plate, and a first driving cylinder for driving the positioning clamps to open or retract; the positioning clamps include a pressure block, a first movable block and a second movable block, and the driving rod of the first driving cylinder is connected to the pressure block.

[0006] To optimize the above technical solution, the present invention also includes the following improved technical solutions.

[0007] The aforementioned positioning clamp has a bidirectional wedge structure. The front and rear sides of the pressure block are respectively provided with a first mounting part and a second mounting part. The first movable block is provided with a first inclined groove for the first mounting part to be installed, and the second movable block is provided with a second inclined groove for the second mounting part to be installed.

[0008] The aforementioned positioning mounting top plate is equipped with a limiting plate, and each end of the limiting plate has a limiting groove for limiting the opening and closing degree of the positioning fixture.

[0009] The aforementioned positioning fixture has a first spring and a second spring built in. One end of the first spring abuts against the pressure block, and the other end of the first spring abuts against the first movable block; one end of the second spring abuts against the pressure block, and the other end of the second spring abuts against the second movable block.

[0010] The aforementioned first lifting cylinder is vertically installed on the lower surface of the positioning and mounting base plate. The drive rod of the first lifting cylinder is provided with a first lifting cylinder connector. The first lifting cylinder connector is connected to a first connecting plate, and the first connecting plate is connected to the positioning and mounting top plate.

[0011] The aforementioned positioning and mounting base plate has a first mounting plate and a second mounting plate at both ends, and a second connecting plate and a third connecting plate at both ends. The second connecting plate is slidably mounted on the first mounting plate via a first slide rail, and the third connecting plate is slidably mounted on the second mounting plate via a second slide rail.

[0012] Compared with the prior art, the mop plate positioning mechanism of this utility model allows the first lifting cylinder to drive the positioning clamp to move up and down when the mop plate moves to the feeding positioning mechanism. The positioning clamp is then inserted into the first locking part at the rear end of the mop plate. The first driving cylinder drives the positioning clamp to open, and the positioning clamp is locked and fixed to the first locking part at the rear end of the mop plate. If there is a deviation in the position of the mop plate at the feeding positioning mechanism, the positioning clamp in the retracted state can still pass upward through the first locking part, and the positioning clamp can appropriately correct the position of the mop plate to ensure the normal operation of subsequent processes.

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses a mop plate positioning mechanism for a bag sewing machine, comprising a positioning mounting base plate 1 and a lifting positioning mounting top plate 2 above the positioning mounting base plate 1. The positioning mounting base plate 1 is equipped with a first lifting cylinder 3 for driving the positioning mounting top plate 2 to move up and down. Positioning clamps 4 are respectively positioned at both ends of the positioning mounting top plate 2. The positioning mounting top plate 2 is also equipped with a first driving cylinder 5 for driving the positioning clamps 4 to open or retract. The mop plate positioning mechanism is located behind the feeding positioning mechanism. The positioning clamps 4 lock and fix the mop plate 15 located at the feeding positioning mechanism, preventing misalignment of the mop plate 15 and ensuring the normal operation of subsequent processes.

[0021] The cylinder body of the first lifting cylinder 3 is vertically mounted on the lower surface of the positioning mounting base plate 1. The drive rod of the first lifting cylinder 3 is connected to the first lifting cylinder connector 6. The first lifting cylinder connector 6 is connected to the first connecting plate 7, which is connected to the positioning mounting top plate 2. The first lifting cylinder 3 can drive the positioning mounting top plate 2 to move up and down.

[0022] The positioning and mounting base plate 1 has a first mounting plate 8 and a second mounting plate 9 at both ends, and the positioning and mounting top plate 2 has a second connecting plate 10 and a third connecting plate 11 at both ends. A first slide rail 12 is vertically mounted on the first mounting plate 8, and a first slider that can move up and down along the first slide rail 12 is mounted on the second connecting plate 10. A second slide rail 13 is vertically mounted on the second mounting plate 9, and a second slider that can move up and down along the second slide rail 13 is mounted on the third connecting plate 11. The positioning and mounting top plate 2 can move up and down along the first slide rail 12 and the second slide rail 13 at both ends.

[0023] The cylinder body of the first drive cylinder 5 is vertically mounted on the lower surface of the positioning mounting top plate 2, and the first drive cylinder 5 is connected to the positioning fixture 4. The positioning fixture 4 includes a pressure block 4a, a first movable block 4b, and a second movable block 4c. The drive rod of the first drive cylinder 5 is connected to the pressure block 4a. The positioning fixture 4 has a bidirectional wedge structure. The front and rear sides of the pressure block 4a are respectively provided with a first mounting part 4d and a second mounting part 4e. The first movable block 4b is provided with a first inclined groove for mounting the first mounting part 4d, and the second movable block 4c is provided with a second inclined groove 4f for mounting the second mounting part 4e. The first mounting part 4d is inserted into the first inclined groove, and the second mounting part 4e is inserted into the second inclined groove 4f. The pressure block 4a moves in coordination with the first movable block 4b and the second movable block 4c.

[0024] like Figure 3 As shown, when the first drive cylinder 5 drives the pressure block 4a to move downward, the pressure block 4a presses down on the first movable block 4b and the second movable block 4c. Since the lower surfaces of the first movable block 4b and the second movable block 4c abut against the upper surfaces of the positioning and mounting top plate 2, the pressure block 4a presses the first movable block 4b and the second movable block 4c and moves them outward in parallel, thereby achieving the purpose of clamping the workpiece.

[0025] The positioning fixture 4 contains a first spring and a second spring. One end of the first spring abuts against the pressure block 4a, and the other end abuts against the first movable block 4b. One end of the second spring abuts against the pressure block 4a, and the other end abuts against the second movable block 4c. When the pressure block 4a moves downward, the first and second springs are compressed. When the first drive cylinder 5 moves the pressure block 4a upward, the first and second springs return to their initial states, so the first and second movable blocks 4b and 4c do not move upward with the pressure block 4a. At this time, the first mounting part 4d of the pressure block 4a pulls the first movable block 4b inward, and the second mounting part 4e of the pressure block 4a pulls the second movable block 4c inward, thereby achieving the purpose of unlocking the workpiece.

[0026] A limiting plate 14 is provided on the positioning and mounting top plate 2. Limiting grooves 14a are respectively formed at both ends of the limiting plate 14. The limiting grooves 14a are used to limit the opening and closing degree of the positioning fixture 4. When the first driving cylinder 5 drives the pressure block 4a to move downward, the first movable block 4b and the second movable block 4c move outward in the limiting groove 14a at the same time.

[0027] like Figure 4 As shown, the rear end of the mop plate 15 is provided with a fixing seat 16. The fixing seat 16 has two rows of first locking parts 16a and second locking parts 16b for easy gripping. The first locking parts 16a are used to cooperate with the mop plate positioning mechanism and the mop mechanism for installation, and the second locking parts 16b are used to cooperate with the pressing and feeding mechanism for installation.

[0028] The clamping component of the mop mechanism grips the mop plate 15, enabling the mop plate 15 to move cyclically between the feeding position and the sewing position. When the mop mechanism moves the mop plate 15 to the feeding position, the first lifting cylinder 3 in the mop plate positioning mechanism drives the positioning mounting top plate 2 to move upward until it is flush with the worktable surface. The positioning clamp 4 on the positioning mounting top plate 2 passes upward through the first locking part 16a in the fixed seat 16. The first driving cylinder 5 drives the pressure block 4a of the positioning clamp 4 to move downward. The first movable block 4b and the second movable block 4c of the positioning clamp 4 lock with the first locking part 16a, realizing the origin positioning function of the mop plate 15.

[0029] If the position of the mop plate 15 at the feeding positioning mechanism is deviated, the positioning clamp 4 in the retracted state can still pass upward through the first locking part 16a in the fixed seat 16. The first driving cylinder 5 drives the pressure block 4a in the positioning clamp 4 to move downward, and the first movable block 4b and the second movable block 4c move outward. The first movable block 4b and the second movable block 4c clamp and fit tightly with the first locking part 16a, correcting the position deviation of the mop plate 15, so that the subsequent mop mechanism can grab the mop plate 15.

[0030] After the material feeding is completed, the first drive cylinder 5 in the mop plate positioning mechanism drives the positioning clamp 4 to unlock from the first locking part 16a, and the first lifting cylinder 3 drives the positioning mounting top plate 2 to move downward. The mop mechanism continues to drive the mop plate 15 to move cyclically between the material feeding position and the sewing position.

[0031] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
