Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to a large plate folding device for patch pocket processing. Background Technology

[0002] Pocket sewing is a common process in garment manufacturing, mainly used to sew pockets onto various garments. This process is usually completed using a dedicated patching machine or a template machine. However, dedicated patching machines are expensive, limiting their widespread use; on the other hand, in template machine processes, the garment and pre-folded pocket pieces need to be manually placed into the template and pressed and fixed. The template is then driven by an XY-axis drive mechanism, and the sewing machine head sews the pockets along a preset track.

[0003] In addition, the large plates in existing template machines are mostly flipped and pressed manually. This method not only has a low degree of automation and affects processing efficiency, but also easily causes wrinkles on the surface of the garment due to uneven pressing force or inaccurate positioning, which in turn has an adverse effect on the subsequent sewing quality. Summary of the Invention

[0004] The purpose of this utility model is to provide a large plate folding device for bag-making, which overcomes the problems of low mechanization and reduced processing efficiency caused by manually rotating the large plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A large plate folding device for bag-making includes a base plate, a large plate hinged to the base plate on one side, and a drive component disposed on a processing table and driving the rotating plate to swing. The rotating plate and the large plate can be connected and engaged by a connecting mechanism to drive the large plate to swing open and close relative to the base plate.

[0006] Preferably, the connecting mechanism includes a suitable insertable pin and pin hole, and the rotating plate and the large plate are connected and fitted through the pin and pin hole.

[0007] Preferably, the rotating plate is rotatably connected to the mounting plate of the processing table, and the driving component is mounted on the mounting plate and drives the rotating plate to swing.

[0008] Preferably, the pin hole is formed on the pin hole buckle, and the pin hole buckle is set on the rotating plate or the large plate.

[0009] Preferably, the turntable is located on one side of the processing table.

[0010] Preferably, the diameter of the pin hole is larger than that of the pin rod.

[0011] The beneficial effects of this utility model are: The rotating plate and the large plate are connected by a connecting mechanism. The rotating plate drives the large plate to swing, which effectively improves the mechanization level and overall production efficiency of pocket sewing. At the same time, it makes the pressing action of the large plate smoother and avoids uneven pressure or positional deviation of the large plate caused by manual operation, so that the large plate can be pressed more stably and flatly onto the garment, thereby improving the quality of subsequent pocket sewing processing.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0015] like Figures 2-5 As shown, this embodiment discloses a large plate folding device for bag patching processing, including a base plate 12, a large plate 2 hinged to the base plate 12 on one side, and a driving member disposed on the processing table 1 and driving the rotating plate 23 to swing. The large plate 2 is rotatably disposed on the base plate 12, and the large plate 2 can open and close relative to the base plate 12.

[0016] Specifically, the large plate 2 is provided with a hinge 21 connected to the base plate 12, the large plate 2 can rotate along the hinge 21, and a side plate 211 fixed to the hinge 21 is provided on one side of the large plate 2.

[0017] The rotating plate 23 is rotatably connected to the mounting plate 231 of the processing table 1. The mounting plate 231 is fixedly installed on one side of the processing table 1, and the rotating plate 23 is located on one side of the processing table 1. The driving component is installed on the mounting plate 231 and drives the rotating plate 23 to swing. The driving component can be a cylinder, for example, the rotating plate 23 can be driven to swing by a driving cylinder 25.

[0018] The rotating plate 23 and the large plate 2 can be connected and engaged through a connecting mechanism. The connecting mechanism can be any one or more of the following: a pin hole insertion structure, a pin groove insertion structure, a magnetic attraction structure, a clamping structure, etc., to drive the large plate 2 to swing open and close relative to the base plate 12. In this embodiment, a pin rod 24 and a pin hole structure are used. That is, the connecting mechanism in this embodiment includes a suitable pin rod 24 and a pin hole, and the rotating plate 23 and the large plate 2 are connected and engaged through the pin rod 24 and the pin hole.

[0019] Furthermore, the pin hole is opened on the pin hole buckle 22, the diameter of the pin hole is larger than the pin rod 24, and the pin hole buckle 22 is provided on the rotating plate 23 or the large plate 2.

[0020] In this embodiment, a pin 24 is fixed on the rotating plate 23, and a pin hole buckle 22 is provided on the large plate 2 for the pin 24 to be inserted and fixed. The pin 24 is inserted into the pin hole buckle 22 and drives the large plate 2 to swing open and close.

[0021] In this embodiment, the pin 24 is directly fixed to the rotating plate 23, and the driving source for driving it to engage with the pin hole buckle 22 is omitted. Since the template composed of the base plate 12 and the large plate 2 participates in the movement of the pocket during the sewing process on the processing table, the pin hole buckle 22 and the pin 24 can be engaged when moving towards the rotating plate 23.

[0022] By rotating the large plate 2, the pocket is pressed against the garment on the bottom plate 12. That is, the large plate 2 is driven by the rotating plate 23 to swing, which effectively improves the mechanization level and overall production efficiency of pocket sewing. At the same time, it makes the pressing action of the large plate 2 smoother and avoids uneven pressure or positional deviation of the large plate 2 caused by manual operation, so that the large plate 2 can be pressed more stably and flatly against the garment, thereby improving the quality of subsequent pocket sewing processing.

[0023] like Figures 1 to 11 As shown, this embodiment also discloses a bag-applying processing device, including the aforementioned large plate folding device and a sewing machine head 11, which is fixedly placed on the processing table 1. The sewing machine head 11 is located on the processing table 1 and is vertically spaced from the processing table 1. A template has a base plate 12 and a large plate 2 that are hinged to each other and openable. The large plate 2 has a bag-shaped notch. The base plate 12 is used to place the garment to be sewn. The sewing machine head 11 is used to sew the garment. A template moving device 5 is fixedly set on the processing table 1 and is used to drive the template to move. The template moving device 5 drives the template to move laterally on the processing table 1, that is, drives the template to move relative to the sewing machine head 11 in the XY direction. The template moving device 5 can be fixedly connected to the template. For example, a clamping cylinder for clamping the template can be set on the template moving device 5, or a pin for inserting and connecting to the template can be set on the template moving device 5, or an electromagnet for magnetically connecting the template can be set on the template moving device 5, thereby driving the template to move laterally.

[0024] A large plate 2 is rotatably mounted on the base plate 12. One side of the large plate 2 is rotatably mounted on the base plate 12 so that the large plate 2 can open and close relative to the base plate 12. Specifically, the large plate 2 is provided with a hinge 21 connected to the base plate 12. The large plate 2 can rotate along the hinge 21. One side of the large plate 2 is provided with a side plate 211 fixed to the hinge 21.

[0025] A bag-shaped tongue plate 3 is slidably disposed on the large plate 2. The tongue plate 3 is pocket-shaped and is slidably mounted on the large plate 2. A pocket cloth to be folded is placed on the tongue plate 3. A cylinder is provided on the large plate 2 to drive the tongue plate 3 to slide back and forth, thereby realizing the back and forth sliding displacement action of the tongue plate 3.

[0026] A pressure frame 4 is rotatably mounted on the large plate 2 above the tongue plate 3. That is, the pressure frame 4 is positioned above the large plate 2, and the tongue plate 3 is positioned between the large plate 2 and the pressure frame 4. The tongue plate 3 is slidably mounted along the opening and closing rotation axis of the large plate 2. Sliding the tongue plate 3 allows it to be pulled out (removed) from under the pressure frame 4. The pressure frame 4 can rotate relative to the large plate 2. Specifically, a rotating shaft 42 is fixedly connected to the pressure frame 4. The large plate 2 is provided with a driving component connected to the rotating shaft 42 and driving the pressure frame 4 to swing open and close. The driving component drives the rotating shaft 42 to rotate, and the pressure frame 4 can rotate relative to the large plate 2 under the drive of the driving component, thereby causing the pressure frame 4 to swing open or close.

[0027] Specifically, in this embodiment, the driving component of the pressure frame 4 includes a second driving cylinder 44 rotatably mounted on the large plate 2. A rotating seat 43 is fixed on the large plate 2, and the second driving cylinder 44 is rotatably connected to the rotating seat 43. The rotating shaft 42 is fixed to one side of the pressure frame 4. The pressure frame 4 swings and presses against the pocket cloth on the large plate 2. The large plate 2 has a bag-shaped notch that matches the outline of the pocket cloth. The pressure frame 4 rotates along the rotating shaft 42 and presses against the pocket cloth on the tongue plate 3 to press the pocket cloth tightly against the tongue plate 3.

[0028] Specifically, a drive rod 46 is rotatably connected to the piston rod 441 of the second drive cylinder 44. One end of the drive rod 46 is connected to the rotating shaft 42. The second drive cylinder 44 drives the drive rod 46 to rotate the rotating shaft 42, so as to further realize the rotational opening or pressing action of the pressure frame 4.

[0029] The driving component of the pressure frame 4 in this embodiment can also be a gear and rack structure. By connecting the rack to the piston rod of the cylinder, the rack is driven to move linearly, and the gear is fixed on the rotating shaft 42. The gear and rack mesh with each other, and the cylinder drives the rack to move linearly to drive the gear and rotating shaft 42 to rotate, so as to realize the swing opening or pressing action of the pressure frame 4. In this embodiment, the driving component of the pressure frame 4 can also be a slider-crank structure. The crank is fixed to the rotating shaft 42, and one end of the connecting rod of the slider-crank structure is hinged to the crank, while the other end of the connecting rod is hinged to the slider. At the same time, the slider is connected to the piston rod of the cylinder so that the cylinder drives the slider to move linearly, and drives the rotating shaft 42 to rotate through the connecting rod and crank, thereby realizing the swing opening or pressing action of the pressure frame 4.

[0030] Furthermore, compared with the existing direct-drive lifting pressure frame 4, this embodiment achieves the flipping and opening of the pressure frame 4 by rotating the pivot 42, which can effectively avoid the operation area, that is, avoid obstructing the view when placing the pocket cloth, so that the operator can place the pocket cloth more conveniently and flatly, significantly improving the convenience of operation.

[0031] A support rod 45 is rotatably mounted on the large plate 2. The upper end of the support rod 45 is rotatably connected to the drive rod 46. The support rod 45 provides stable support and rotation guidance for the drive rod 46 to drive the rotating shaft 42 to rotate. A connecting rod is provided between the drive rod 46 and the rotating shaft 42, which cooperates with the support rod 45 for transmission. Through the cooperation of the connecting rod and the support rod 35, stable support and rotation guidance are provided for the rotation of the drive shaft 42, so that the rotation of the pressing frame 4 is smoother and more stable. At the same time, it also ensures the positional accuracy and reliability of the pressing frame 4 when pressing the pocket fabric, which is more conducive to improving the quality of subsequent sewing.

[0032] The large plate 2 is provided with folding plates 26 distributed along the edge of the tongue plate 3 and driven by folding cylinders 261. The folding plates 26 can be inserted into the bottom surface of the tongue plate 3 to fold the pocket fabric along the edge of the tongue plate 3. Specifically, the large plate 2 is equipped with folding cylinders 261 that drive the folding plates 26 to extend and retract. The folding cylinders 261 and folding plates 26 are distributed on the outer side of the tongue plate 3. The folding plates 26 slide out to fold the pocket fabric on the tongue plate 3 to fold the pocket fabric to form a pocket.

[0033] To improve the folding effect of the pocket fabric, the bottom surface of the pressure frame 4 is provided with a pressing part corresponding to the tongue plate 3. The pressing part can be a pressure frame sponge 41. Specifically, the pressure frame 4 is provided with a pressure frame sponge 41 that can press against the tongue plate 3. The pressure frame sponge 41 is set on the lower edge of the pressure frame 4 so that the pressure frame sponge 41 that can press against the pocket fabric is provided on the pressure frame 4. The pressure frame sponge 41 presses down on the part of the pocket fabric that exceeds the edge of the tongue plate 3. That is, under the action of the pressure frame sponge 41, the pocket fabric is folded down along the edge of the tongue plate 3, and the pocket fabric is folded inward by the folding plate 26 to form a pocket. In the process of moving and folding the pocket fabric, the folding plate 26 can deform inward and squeeze the pressure frame sponge 41 so that the folding plate 26 can fit more closely to the lower end of the tongue plate 3 to fold the pocket fabric, thereby improving the folding effect of the pocket edge and improving the quality of subsequent pocket sewing.

[0034] Furthermore, when the pocket needs to be sewn later and the plate 26 and the tongue plate 3 are moved away from the pocket, the frame-pressing sponge 41 presses against the edge of the pocket so that the pocket will not deform or move as the plate 26 and the tongue plate 3 move back. In other words, the pressing setting of the frame-pressing sponge 41 ensures the quality of the pocket sewing process.

[0035] The pressure frame 4 has a needle feed notch 411 corresponding to the shape of the pocket-shaped notch in the large plate 2. The needle feed notch 411 is opened on the pressure frame 4 and located inside the pressure frame sponge 41. The large plate 2 has a notch corresponding to the shape of the tongue plate 3. That is, the large plate 2 has a notch corresponding to the pocket position and used for the needle and thread to pass through and sew the sewing machine head 11. The bottom plate 12 also has a notch corresponding to the position and outline of the needle feed notch 411 and used for the needle and thread to pass through and sew the sewing machine head 11 (see reference). Figure 1 , Figure 6 As shown), the large plate 2 can drive the pocket on the tongue plate 3 to flip onto the garment surface of the base plate 12, and clamp the base plate 12 and the large plate 2 with external clamps so that the pocket can fit and press firmly onto the garment. Subsequently, the pocket is sewn onto the garment through the stitch notch 411 and the notch on the base plate 12.

[0036] A toggle plate 33 is fixed on the tongue plate 3. A cylinder on the large plate 2 for driving the tongue plate 3 to slide back and forth can be connected to the toggle plate 33 to drive the tongue plate 3 to slide back and forth.

[0037] Specifically, a connecting plate 31 is provided on the tongue plate 3, and the tongue plate 3 slides laterally along the length direction of the connecting plate 31. The actuating plate 33 is fixed on the connecting plate 31, and a guide block 36 located in the slide groove 321 is fixed on the large plate 2. The connecting plate 31 is slidably installed on the large plate 2 through the cooperation of the guide block 36 and the slide groove 321. The sliding back and forth sliding of the tongue plate 3 is guided by the cooperation of the slide groove 321 and the guide block 36.

[0038] The guide block 36 is fixed on the large plate 2 and attached to the inner wall of the slide groove 321. The guide block 36 fits tightly against the inner wall of the slide groove 321, providing effective displacement guidance when the connecting plate 31 and the tongue plate 3 slide laterally. This significantly enhances the stability of the tongue plate 3 during the lateral sliding process and avoids phenomena such as offset or jamming. This provides a reliable guarantee for the accurate folding and shaping of the pocket fabric, thereby improving the overall quality and consistency of pocket sewing.

[0039] A pressure plate 38 is fixed on the large plate 2 and attached to the upper end of the connecting plate 31. A reinforcing plate 32 is fixed at the lower end of the connecting plate 31. The sliding groove 321 is opened in the reinforcing plate 32. A pressure piece 37 that presses against the reinforcing plate 32 is connected to the guide block 36. The pressure plate 38 and the pressure piece 37 cooperate to abut and limit the sliding of the tongue plate 3, so as to further improve the stability of the connecting plate 31 when sliding laterally on the tongue plate 3.

[0040] When the large plate 2 rotates and presses the pocket against the garment surface of the base plate 12, the tongue plate 3 slides backward to move away from the pocket, thereby pressing the garment and the pocket together between the base plate 12 and the pressure frame 4. The base plate 12 drives the garment and the pocket to move laterally to below the sewing machine head 11, realizing automated sewing of the pocket. This improves sewing efficiency and quality. In this embodiment, by setting a detachable tongue plate 3 and pressure frame 4 on the large plate 2, it can adapt to the sewing processing of pockets of different sizes and shapes, thereby improving the convenience and practicality of pocket sewing processing.

[0041] This embodiment integrates the tongue plate 3, pressure frame 4, and folding plate 26 onto the large plate 2, and coordinates with the base plate 12 to form an integrated modular template. This template is compatible with existing template machines to achieve automated sewing, significantly improving pocket sewing efficiency and quality while effectively reducing equipment investment and production costs. Furthermore, the template has good adaptability and scalability, suitable for processing pockets of different sizes and shapes, thus greatly improving the versatility, convenience, and practicality of pocket sewing. Example

[0042] This embodiment also discloses a bag-applying processing device. The difference between this embodiment and embodiment 1 is that this embodiment does not provide a cylinder for driving the tongue plate 3 to slide back and forth. Specifically, the front and rear sides of the actuating plate 33 are provided with a top plate 1 34 and a top plate 2 35 that are relatively distributed. The top plate 1 34 and the top plate 2 35 are respectively fixed to the sewing machine head 11 and the large plate 2. The top plate 1 34 and the top plate 2 35 abut against the actuating plate 33 and drive the tongue plate 3 to slide back and forth, so as to be able to move in and out under the pressure frame 4. That is, the tongue plate 3 can slide to move under the pressure frame 4 or slide away from the pressure frame 4.

[0043] A top plate 34 and a top plate 35 are provided along the transverse direction of the template to abut against the actuating plate 33. That is, by distributing the top plate 34 and the top plate 35 opposite to each other on the front and rear sides of the actuating plate 33 on the tongue plate 3, as the tongue plate 3 moves forward with the large plate 2 and approaches the sewing machine head 11, the actuating plate 33 abuts against the top plate 34 and drives the tongue plate 3 and the abutting plate 33 to slide backward, so that the tongue plate 3 automatically pulls back away from the pocket, so as to avoid the tongue plate 3 interfering with the subsequent sewing of the pocket.

[0044] After the pocket is sewn, the tongue plate 3 moves backward with the large plate 2 to reset. At this time, the actuating plate 33 abuts against the top plate 35 and drives the tongue plate 3 to move forward automatically so that the pocket fabric can be quickly placed on the tongue plate 3 during the next processing.

[0045] By adjusting the forward and backward displacement of the tongue plate 3, the existing cylinder that drives the tongue plate 3 to move is eliminated. This reduces the installation load on the large plate 2 while ensuring the reliable and stable operation of the tongue plate 3, thereby improving the smoothness of the rotation of the large plate 2 and thus enhancing the quality of pocket sewing.

[0046] Meanwhile, the template in this embodiment can be adapted to existing template machines, thereby achieving a processing effect similar to that of existing patching machines. In addition, the template, by setting a pocket-shaped tongue 3, can accurately position and shape the pocket fabric, effectively avoiding problems such as displacement or detachment that are easy to occur when manually placed. During the processing, the template can be moved laterally to the sewing machine head 11 to sew the pocket, which not only ensures the consistency of the stitches and the sewing accuracy, but also significantly improves the automation level and production efficiency of the patching process, thereby reducing equipment investment costs and dependence on operator skills to a certain extent. Example

[0047] This embodiment also discloses a bag-applying processing device. The difference between this embodiment and embodiment 2 is that the top plate 25 is fixed on the rotating plate 23, and the top plate 1 34 and the top plate 2 35 are respectively fixed relative to each other on the sewing machine head 11 and the rotating plate 23.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
