Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to a pleating device. Background Art

[0002] When people sew fabrics, especially curtains, bedspreads or some fashionable clothes, they often need to pleat some parts. The existing pleating device usually includes a transmission mechanism, a swing rod and a feeding shovel. The swing rod converts the rotation of the transmission mechanism into the reciprocating motion of the feeding shovel. The feeding shovel feeds the fabric to the sewing machine by friction, so that the fabric is folded continuously.

[0003] For example, a Chinese patent application (application number: 201410505505.3) discloses a high-speed automatic pleating device for an industrial sewing machine, including a transmission shaft, a swing frame connecting rod and a feeding shovel; a small gear is fixedly arranged on the transmission shaft, a large gear meshing with the small gear is arranged above the small gear, and the large gear is fixedly arranged on a first shaft arranged parallel to the transmission shaft; a first adjusting eccentric wheel is fixedly arranged at the end of the first shaft, and a second adjusting eccentric wheel is fixedly arranged at the end of the transmission shaft, the first adjusting eccentric wheel is connected to one end of the first eccentric connecting rod through a fisheye joint, and the second adjusting eccentric wheel is connected to one end of the second eccentric connecting rod through a fisheye joint, and the first adjusting eccentric wheel is connected to one end of the second eccentric connecting rod through a fisheye joint. The other end of the second eccentric connecting rod is connected to the swing frame connecting rod through a fisheye joint; the top of the swing frame connecting rod is fixed on a second shaft arranged parallel to the transmission shaft, and a steering crank is rotatably mounted on the second shaft, and the other end of the first eccentric connecting rod is connected to the bottom end of the steering crank through a fisheye joint; the bottom of the swing frame connecting rod is rotatably mounted with a shovel blade mounting shaft connecting column; a shovel blade mounting shaft is fixed to one end of the shovel blade mounting shaft connecting column, and a feeding shovel blade is mounted on the shovel blade mounting shaft, and the other end of the shovel blade mounting shaft connecting column is connected to the bottom end of the connecting rod through a fisheye joint, and the top of the connecting rod is connected to the top end of the steering crank through a fisheye joint.

[0004] Although the existing pleating device as mentioned above can achieve stable pleating, it still has the following defects: because the running trajectory of the feeding shovel determines the visual effect of the final pleating after pleating, that is, the depth of pleating or the angle of pleating are different, resulting in different pleating. In the existing pleating device, the feeding shovel relies on the action of the swing frame connecting rod and the transmission mechanism to convert the rotation of the motor into the reciprocating swing of the feeding shovel to achieve pleating, that is, the reciprocating motion trajectory of the existing feeding shovel is along the swinging circular trajectory of its swing frame connecting rod, and the pleating trajectory is fixed, so the fabric can only be pleated with a fixed pleating effect, which cannot meet the pleating requirements of different fabrics for different pleating effects or the same fabric for different pleating effects.

[0005] In order to achieve the needs of fabrics for different pleating effects, the conventional practice is to replace or adjust the transmission mechanism to adjust the swing amplitude of the swing frame connecting rod, thereby adjusting the running trajectory of the feeding shovel. This is inconvenient to operate and requires the installation of multiple different transmission mechanisms, which is costly and still cannot achieve arbitrary changes in the pleating effect. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a pleating device. The technical problem to be solved by the present invention is: how to solve the problem that the existing pleating device cannot meet the pleating requirements of fabrics for different pleating effects.

[0007] The objective of the present invention can be achieved through the following technical solutions: a pleating device, comprising a frame, a motor and a shovel head, wherein the motor is fixed on the frame, and is characterized in that the pleating device also comprises a driving member capable of driving the shovel head to move linearly, a transmission mechanism is provided between the motor and the driving member, and the rotation of the motor can drive the driving member to swing relative to the frame through the transmission mechanism.

[0008] The pleating device redesigns the structure to connect the motor to the driving member, the shovel head is fixedly connected to the driving member, the motor is used to drive the driving member to swing relative to the frame, and then the driving member drives the shovel head to move linearly to achieve pleating. That is, when the shovel head achieves pleating, its running track is composed of the swinging circular track of the driving member driven by the motor plus the linear track of the shovel head driven by the driving member. When pleating, when the fabric has different pleating effects, the pleating track can be adjusted by controlling the time difference between the operation of the motor and the driving member. For example, the first pleating situation is: by controlling the motor to run for 10 seconds to form a swinging circular trajectory, and then controlling the driving member to drive the shovel head to move linearly and contact the fabric for pleating, the time difference is 10 seconds; the second pleating situation is: controlling the motor to run for 12 seconds to form a swinging circular trajectory, and then controlling the driving member to drive the shovel head to move linearly and contact the fabric for pleating, the time difference is 12 seconds; and due to the difference in these two time differences, the running trajectory of the shovel head is also different, that is, the amplitude of the swing of the motor driving the driving member is different, and the distance and angle formed between the shovel head on the driving member and the fabric after the swing are also different. After the driving member drives the shovel head to move linearly, the angle and depth of its pleating are also different, so that different pleating effects can be achieved. In other words, the pleating device changes the existing conventional pleating trajectory and pleating method through the synergistic effect of the motor and the driving member. It only needs to control the running time difference of the motor and the driving member to make the shovel head form different motion trajectories, thereby achieving the effect of adjusting the pleating angle and pleating depth, and can meet the pleating requirements of different fabrics for different pleating effects or the same fabric for different pleating effects.

[0009] In the above-mentioned pleating device, the pleating device also includes a connecting seat, the connecting seat is swingably connected to the frame, the driving member is fixed on the connecting seat, the connecting seat has two side plates and a guide channel is formed between the two side plates, the driving member has a piston rod and the piston rod is connected to the shovel head through a guide plate, and the guide plate is slidably connected in the above-mentioned guide channel. The driving member is a cylinder or a hydraulic cylinder, and the piston rod of the driving member can drive the shovel head to make a linear reciprocating motion by telescoping. Through the coordinated design of the guide channel and the guide plate, the left and right sides of the shovel head are limited, so that the shovel head has better stability in linear reciprocating motion. At the same time, with the action of the motor, the shovel head can form a stable swinging circular trajectory and a linear trajectory, and the pleating trajectory is adjusted by controlling the time difference between the operation of the motor and the driving member, so that different pleating effects can be achieved.

[0010] In the above-mentioned pleating device, guide grooves connected to the guide channel are provided on the opposite side walls of the two side plates, and the two side edges of the guide plates are respectively embedded in the corresponding guide grooves. The structural design of the guide groove further limits the upper and lower sides of the shovel head, so that the shovel head has better stability in linear reciprocating motion. At the same time, with the action of the motor, the shovel head can form a stable swinging circular trajectory and a linear trajectory, and the pleating trajectory can be adjusted by controlling the time difference between the operation of the motor and the driving member, so that different pleating effects can be achieved.

[0011] In the above-mentioned pleating device, the frame has a head for sewing, the motor is arranged above the head, the shovel head is located on one side of the head, the transmission mechanism includes a screw rod, a nut and a connecting rod assembly, the screw rod is fixedly connected to the rotating shaft of the motor, the nut is threadedly connected to the screw rod, and the nut is connected to the connecting seat through a connecting rod assembly. The rotation of the motor can drive the screw rod to rotate, the screw rod drives the nut to slide, and the nut drives the connecting rod assembly to link so that the driving member swings relative to the frame. The rotation of the motor is converted into the swing of the driving member by the screw rod and the nut in cooperation with the connecting rod mechanism, the transmission accuracy is high, and the screw rod and the nut have a self-locking function after the motor stops rotating, so that by controlling the time difference between the operation of the motor and the driving member, the pleating trajectory can be accurately and stably adjusted, so that different pleating effects can be achieved. As an alternative, the transmission mechanism can be a cam and a connecting rod assembly, the cam is connected to the rotating shaft of the motor, the rotation of the rotating shaft of the motor drives the cam to rotate, and the cam drives the connecting rod assembly to link to realize the swing of the driving member.

[0012] In the above-mentioned pleating device, the connecting rod assembly includes a swing rod and a connecting rod, the middle part of the swing rod is hinged on the machine head, one end of the swing rod is hinged to the nut, and the other end is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to the connecting seat, and the connecting seat is hinged on the machine head. The rotation of the motor can drive the screw rod to rotate, the screw rod drives the nut to slide, the nut pushes the swing rod to swing around the middle hinge, thereby driving the connecting rod to swing around the hinge point, and then pushes the connection to swing relative to the machine head, so that the shovel head forms a swinging circular trajectory, and the pleating trajectory is adjusted by controlling the time difference between the operation of the motor and the driving member, so that different pleating effects can be achieved.

[0013] In the above-mentioned pleating device, one end of the swing rod has two hinged arms, and a hinge groove is formed between the two hinged arms. The fixed sleeve on the nut is provided with a connecting sleeve, and the connecting sleeve is embedded in the hinge groove. Both sides of the connecting sleeve have protruding hinge lugs, and the two hinged lugs are hinged to the two hinged arms through hinge shafts. The hinged connection is achieved by the two hinged lugs and the two hinged arms, so that the movement of the nut can more smoothly push the swing rod to swing around the middle hinge. At the same time, it can also avoid the local reverse force on the nut, which causes the thread between the nut and the screw rod to get stuck, ensuring normal transmission, so that the pleating trajectory can be adjusted by controlling the time difference between the operation of the motor and the drive member, so that different pleating effects can be achieved.

[0014] In the above-mentioned pleating device, a swing arm is also fixed on the connecting seat, one end of the swing arm extends between the two side plates and is fixedly connected to the two side plates, a 7-shaped structure is formed between the swing arm and the two side plates, the other end of the swing arm is hinged on the top of the machine head, and the connecting rod is hinged to the end of the side plate away from the swing arm. The swing arm and the two side plates form a 7-shaped structure, the overall structure is more reasonable, the swing is more stable, and the swing amplitude is wider, so that the pleating trajectory can be better adjusted by controlling the time difference between the operation of the motor and the driving member, so that different pleating effects can be achieved.

[0015] In the above-mentioned pleating device, embedding grooves are also provided on both sides of the swing arm, and the two side plates are embedded in the corresponding embedding grooves. Through the above-mentioned arrangement, the structure between the swing arm and the two side plates is more stable and the installation is more convenient. At the same time, since the driving member is fixed on the two side plates, the gravity of the driving member is supported by the two side plates, and its gravity direction is inclined downward. The side plates are embedded in the corresponding embedding grooves. Due to the effect of the gravity of the driving member, the edges of the two side plates can be clamped on the two side groove walls of the embedding groove respectively, so that the swing arm and the two side plates can maintain a relatively stable structure without looseness, thereby ensuring the accuracy of pleating.

[0016] In the above-mentioned pleating device, a mounting seat is fixed above the machine head, the motor is fixed on the mounting seat, and the swing arm is hinged on the mounting seat and is located on one side of the motor. Through the above-mentioned arrangement, the overall structure is more compact.

[0017] In the above-mentioned pleating device, the guide plate includes a plate 1 connected to the piston rod and a plate 2 connected to the shovel head, and a Z-shape is formed between one side of the plate 1 and the plate 2. The guide plate forms a Z-shaped structure on one side, so that the main force of the shovel head when pleating is concentrated on the Z-shaped side of the guide plate, thereby shifting the reaction force to one side of the guide plate. Due to the unique Z-shaped structure, part of the reaction force can be transmitted to the side plate through the guide plate, thereby reducing the reaction force on the driving part during the pleating process, eliminating stress concentration, and extending the service life. At the same time, through the transmission of the above-mentioned force, during the pleating process, the guide plate occasionally transmits the reaction force to the side plate, which can cause slight vibrations in the side plate, and can prevent dust and thread hair generated by sewing from accumulating between the guide plate and the side plate, avoid jamming between the two, and ensure smooth operation.

[0018] In the above-mentioned pleating device, a dust cover is also provided on the mounting seat, and the screw rod, nut and swing arm are all located in the dust cover. The design of the dust cover can well prevent dust in the air and thread hair generated during the fabric sewing process from entering the screw rod, nut and swing arm and other components, thereby avoiding jamming of the entire structure transmission.

[0019] Compared with the prior art, the pleating device has the following advantages:

[0020] 1. Through the synergistic effect of the motor and the driver, the existing conventional pleating trajectory and pleating method are changed. By simply controlling the running time difference between the motor and the driver, the shovel head can form different motion trajectories, thereby adjusting the pleating angle and pleating depth, which can meet the pleating needs of different fabrics for different pleating effects or the same fabric for different pleating effects.

[0021] 2. The screw rod and nut cooperate with the connecting rod mechanism to convert the rotation of the motor into the swing of the driving part. The transmission accuracy is high. Moreover, the screw rod and the nut have a self-locking function after the motor stops rotating. It has good stability, high adjustment accuracy and good pleating effect.

[0022] 3. The overall structure is compact and the operation is relatively easy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] Embodiment 1

[0036] like Figure 1-8 As shown, the pleating device comprises a frame 1, a motor 2, a shovel head 3, a connecting seat 6 and a driving member 4 capable of driving the shovel head 3 to move linearly. The driving member 4 is a cylinder or a hydraulic cylinder. In this embodiment, the driving member 4 is a cylinder.

[0037] Specifically, the frame 1 has a machine head 1a for sewing, a mounting seat 9 is fixed above the machine head 1a, and the motor 2 is fixed on the mounting seat 9. The connecting seat 6 has two side plates 6a and a swing arm 6c, one end of the swing arm 6c extends between the two side plates 6a and two sides of the end are also provided with an embedding groove 6c1, the two side plates 6a are embedded in the corresponding embedding groove 6c1 and are fixedly connected to the swing arm 6c through fasteners, and a 7-shaped structure is formed between the swing arm 6c and the two side plates 6a, and the other end of the swing arm 6c is hinged on the mounting seat 9 and the hinge point is located on one side of the motor 2, and the overall structure is relatively compact.

[0038] The driving member 4 is located between the two side plates 6a and fixed to the two side plates 6a by fasteners. The driving member 4 has a piston rod and an L-shaped connecting plate is fixedly connected to the piston rod. A guide plate 7 is fixed to the bottom of the connecting plate, and the guide plate 7 is fixedly connected to the shovel head 3. The two sides of the connecting plate and the two sides of the guide plate 7 form a step-like structure, and a guide channel 6b is formed between the two side plates 6a. The opposite side walls of the two side plates 6a are provided with guide grooves 6a1 connected to the guide channel 6b. The two side edges of the connecting plate can be abutted against the two side walls of the guide channel 6b. The guide plate 7 is slidably connected in the guide channel 6b, and the two side edges of the guide plate 7 are respectively embedded in the corresponding guide grooves 6a1, and the two side edges of the guide plate 7 are respectively abutted against the groove walls of the two guide grooves 6a1, which is equivalent to forming a step groove structure on the two side plates 6a. At the same time, the two sides of the guide plate 7 and the two side edges of the connecting plate form a step-shaped slider structure, thereby limiting the left and right sides and the upper and lower sides of the shovel head 3, so that the shovel head 3 has better stability in linear reciprocating motion, and even if one side of the connecting plate or the guide plate 7 is worn, it can maintain good stability. The guide plate 7 includes a plate 1 connected to the connecting plate and a plate 2 connected to the shovel head 3. The plate 1 is a rectangular plate, and the plate 2 is a trapezoidal plate. The wide side of the plate 1 is connected to the lower bottom side of the plate 2 as a whole. The width of the wide side of the plate 1 is smaller than the length of the lower bottom side of the plate 2, and the connection between the two is an arc transition, so that the guide plate 7 forms a Z-shaped structure on one side. The shovel head 3 is in the form of a sheet, and the shovel head 3 is fixed to the plate 2 near the upper bottom edge. One side of the shovel head 3 extends out of the plate 2, so that the main force of the shovel head 3 when pleating is in operation is concentrated on the Z-shaped side of the guide plate 7, thereby shifting the reaction force to one side of the guide plate 7. Due to the unique Z-shaped structure at this point, a part of the reaction force can be transmitted to the side plate through the guide plate 7, thereby reducing the reaction force on the drive member 4 during the pleating process, eliminating stress concentration, and extending the service life. At the same time, through the transmission of the above-mentioned force, during the pleating process, the guide plate 7 occasionally transmits the reaction force to the side plate, which can cause slight vibrations in the side plate, thereby preventing dust and thread hair generated by sewing from accumulating between the guide plate 7 and the side plate, avoiding jamming between the two, and ensuring smooth operation.

[0039] A transmission mechanism 5 is provided between the motor 2 and the driving member 4 , and the rotation of the motor 2 can drive the driving member 4 to swing relative to the frame 1 through the transmission mechanism 5 .

[0040] Furthermore, the transmission mechanism 5 includes a screw rod 5a, a nut 5b and a connecting rod assembly. The screw rod 5a is fixedly connected to the rotating shaft of the motor 2 through a coupling, and the nut 5b is threadedly connected to the screw rod 5a. The transmission accuracy of the screw rod 5a and the nut 5b is high, and the screw rod 5a and the nut 5b have a self-locking function after the motor 2 stops rotating, which is convenient for precise control. A connecting sleeve 8 is sleeved on the nut 5b, and the nut 5b also has an annular flange formed by folding outwards, and one end of the connecting sleeve 8 is in contact with the annular flange and is fixed to the annular flange by a fastener. The connecting rod assembly includes a swing rod 5c and a connecting rod 5d. The middle part of the swing rod 5c is hinged on the machine head 1a. One end of the swing rod 5c has two hinged arms 5c1. A hinge groove 5c2 is formed between the two hinged arms 5c1. A connecting sleeve 8 is embedded in the hinge groove 5c2. Both sides of the connecting sleeve 8 have protruding hinge lugs 8a. The two hinge lugs 8a are respectively hinged with the two hinged arms 5c1 through hinge shafts, so that the movement of the nut 5b can more smoothly push the swing rod 5c to swing around the middle hinge. At the same time, it can also avoid the local reverse force of the nut 5b, which causes the thread between the nut 5b and the screw rod 5a to be stuck, ensuring normal transmission. The connecting rod 5d includes an articulated sleeve and two connecting arms spaced apart on the side wall of the articulated sleeve. The other end of the swing rod 5c extends between the two connecting arms and is hinged with the connecting arms through the articulated shaft. The articulated sleeve is also hinged with the connecting seat 6 through the articulated shaft.

[0041] In addition, a material blocking plate 12 is fixed to the connection seat 6. The material blocking plate 12 is located on the side of the shovel head 3 away from the machine head 1a and is fixed to the connection seat 6 through an L-shaped connecting plate. The width of the material blocking plate 12 is much larger than the width of the shovel head 3. In this embodiment, a control panel is also provided on the machine head 1a. The control panel is a PLC. The motor 2 and the driving member 4 are both connected to the control panel, and the control panel can control the operation of the motor 2 or the driving member 4.

[0042] A dust cover 10 is also provided on the mounting seat 9, and the screw rod 5a, the nut 5b and the swing arm 5c are all located below the dust cover 10, which can effectively prevent dust in the air and thread hair generated during the fabric sewing process from entering the screw rod 5a, the nut 5b and the swing arm 5c and other components to avoid jamming of the entire structure transmission.

[0043] The running track of the shovel head 3 of the pleating device when realizing pleating is composed of the swinging circular track driven by the motor 2 and the linear track driven by the driving member 4 to drive the shovel head 3 to move linearly. When it is working, when the fabric has different pleating effects, the time difference between the operation of the motor 2 and the driving member 4 can be controlled by the control panel to adjust the pleating track. For example, the first pleating situation is: by setting parameters on the control panel, the driving member 4 starts to run again after the motor 2 runs for 10 seconds, that is, the motor 2 rotates to drive the screw rod 5a to rotate, the screw rod 5a drives the nut 5b to slide, the nut 5b pushes the swing rod 5c to swing, the swing rod 5c drives the connecting rod 5d to swing, thereby driving the connecting seat 6 to swing around the hinge, after the motor 2 runs for 10 seconds to form a swinging circular track, the motor 2 stops running, and then the driving member 4 runs, driving the shovel head 3 to move linearly and contact the fabric to pleat, and the time difference is 10 seconds. The second pleating situation is: by setting parameters on the control panel, the driving member 4 starts to run after the motor 2 runs for 12 seconds, that is, the rotation of the motor 2 drives the screw rod 5a to rotate, the screw rod 5a drives the nut 5b to slide, the nut 5b pushes the swing rod 5c to swing, the swing rod 5c drives the connecting rod 5d to swing, thereby driving the connecting seat 6 to swing around the hinge, and after the motor 2 runs for 12 seconds to form a swinging circular trajectory, the motor 2 stops running, and then the driving member 4 runs to drive the shovel head 3 to move linearly and contact the fabric for pleating, and the time difference is 12 seconds; and due to the difference in these two time differences, the running trajectory of the shovel head 3 is also different, that is, the amplitude of the swing driven by the motor 2 to drive the driving member 4 is different, and the distance and angle formed between the shovel head 3 on the driving member 4 and the fabric after the swing are also different. After the driving member 4 drives the shovel head 3 to move linearly, the angle and depth of the pleating are also different. That is to say, the pleating device changes the existing conventional pleating trajectory and pleating method through the coordinated cooperation between the motor 2 and the driving member 4. Only by controlling the running time difference between the motor 2 and the driving member 4, the shovel head 3 can form different motion trajectories, thereby achieving the effect of adjusting the pleating angle and the pleating depth, and can meet the pleating requirements of different fabrics for different pleating effects or the pleating requirements of the same fabric for different pleating effects.

[0044] Embodiment 2

[0045] The structure of this embodiment is basically the same as that of the first embodiment, except that: Figure 9-10 A dust cover 11 capable of covering the guide channel 6b is also fixed to the end surface of one end of the two side plates 6a away from the shovel head 3, and a mounting rail 13 is also fixed to the bottom of the connecting seat 6, and a mounting slide block 14 is provided on the mounting slide rail 13. The baffle plate 12 is abutted against the back of the mounting slide rail 13 and is threadedly connected and clamped on the mounting slide rail 13 by bolts that pass through the baffle plate 12 and the mounting slide rail 13 in sequence, and the mounting slide block 14 is threaded and clamped, and the position of the baffle plate 12 is adjustable.
