Description

TECHNICAL FIELD

[0001] The present application relates to the field of garment processing equipment, in particular to a bagging machine concave die device and a bagging machine. BACKGROUND

[0002] The bagging machine is a commonly used machine in current garment production, which is used for folding and sewing garment pockets. When the bagging machine folds the pocket, the pocket-shaped plate and the concave die are usually used to clamp the pocket-shaped cloth, and then the folding knives, i.e. the cloth folding pieces, perform folding actions, so as to finally realize the folding and forming of the pocket.

[0003] In order to achieve the best folding effect, the distance from the inner frame of the concave die to the periphery of the pocket-shaped plate needs to be designed and processed according to the thickness of the pocket-shaped cloth. When the pocket pattern does not change and the thickness of the pocket-shaped cloth changes, the concave die needs to be attached to different thicknesses of sponge pads to adapt to the changes in the thickness of the pocket-shaped cloth. When the thickness of the pocket-shaped cloth changes greatly, the entire concave die needs to be replaced. Furthermore, for pockets of the same pattern and different sizes, the entire set of pocket-shaped plates, concave dies and cloth folding pieces need to be replaced, so a long time is required for debugging to achieve a better folding and forming effect, which affects the production efficiency and requires a high level of operation.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways without being limited to the embodiments described herein below, and it is therefore clear that the present application is not limited by the embodiments disclosed below.

[0066] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there can be a middle component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there can be a middle component.

[0067] In addition, the terms "first", "second", etc. are used only for the purpose of description and should not be understood as indicating or implying relative importance or an implied indication of the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0068] In the present application, unless otherwise explicitly specified and limited, a first feature is "on", "under", "above" or "over" a second feature can be that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, the first feature is "above", "over" or "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature is higher than the second feature in horizontal height (or in a use state, or in a certain drawing perspective).

[0069] Unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. The use of the terms "and / or" in the present application includes any and all combinations of one or more of the associated listed items.

[0070] Referring to Figures 1 to 6 In an embodiment of the present application, a concave mold device of a bag pasting machine is provided, which includes a concave mold 200 for defining a bag-shaped area 600. The concave mold 200 has a concave mold wall cooperating with the edge of the bag-shaped plate. The bag-shaped area 600 can refer to the area enclosed by the concave mold wall. Although the bag-shaped area 600 can be adaptively scaled when the bag shape changes, it has a relatively bag mouth side 610 and a bag bottom side 620 as a whole. The bag mouth side 610 and the bag bottom side 620 can be understood as specific parts of the bag-shaped area 600 itself, and can be understood as the general orientation and area when referring to other components. A center line 630 extends between the bag mouth side 610 and the bag bottom side 620, and is generally the axis of symmetry of the bag-shaped area 600.

[0071] The concave mold 200 of the present application adopts a split structure, i.e. includes a plurality of unit molds, which can be adjusted in position respectively to scale the concave mold 200, i.e. to change the bag-shaped area 600. In terms of the whole concave mold wall, it can be understood that each unit mold provides one part of the unit wall. In the embodiment, the plurality of position-adjustable unit molds specifically include:

[0072] Two first unit molds 210 are located at the bag mouth side 610 and arranged on both sides of the center line 630 respectively. The position adjustment direction of each first unit mold 210 is perpendicular to the center line 630;

[0073] A plurality of second unit molds 220 are arranged around the bag-shaped area 600 from the bag mouth side 610 to the bag bottom side 620. The position adjustment direction of each second unit mold 220 is parallel or obliquely arranged to the center line 630.

[0074] Unless otherwise specified, the overall layout of each unit module and each set of folding knife components 300 in this application is symmetrical about the center line 630, but the symmetry of the specific structure is not strictly limited based on this, especially the mirror synchronization is not strictly limited when they move or adjust their positions.

[0075] by Figure 4a Taking the orientation in the middle as an example, the left side of the center line 630 shows the state of each unit module before the position adjustment, and the right side of the center line 630 shows the state of each unit module after the position adjustment.

[0076] When the bag shape changes and the overall size of the die 200 needs to be adjusted, if each unit die moves diagonally downward (one of which is taken as an example in the direction of arrow L) and moves away from each other, the die 200 will expand and move downward as a whole, deviating from the previous reference position. Especially when the bag opening folding knife assembly 330 is configured, since the bag opening folding knife assembly 330 generally does not move along the center line 630, the die 200 will move away from the bag opening folding knife assembly 330 as a whole, affecting the cooperation effect and potentially resulting in poor folding effect of the bag fabric.

[0077] This application divides the unit molds into a first unit mold 210 that moves perpendicular to the center line 630 and a second unit mold 220 that moves parallel or obliquely relative to the center line 630, based on the position adjustment trend. When adjusting the position of the first unit mold 210, it moves laterally in the direction of arrow W in the figure, and its projection position on the center line 630 remains unchanged. It can be used as the position reference for the entire die 200. That is, the overall scaling of the die 200 is relative to the movement path of the first unit mold 210. This also provides an initial reference for the assembly and motion control of the equipment, simplifies the design and processing, and ensures the coordination between the die 200 and the surrounding mating parts before and after adjustment.

[0078] In terms of providing the positional reference for the entire die 200, there are two first unit dies 210 arranged on both sides of the centerline 630. However, in terms of the positional adjustment trend of the unit dies, it is not strictly limited to only two first unit dies 210. Although two are used as examples in each figure, more can be set as needed.

[0079] Multiple second unit molds 220 move closer to each other during position adjustment to reduce the size of the die cavity 200 and the gap between the die cavity wall and the edge of the bag-shaped plate, or move further apart during position adjustment to expand the die cavity 200 and increase the gap between the die cavity wall and the edge of the bag-shaped plate. Since the positions of the two first unit molds 210 serve as a reference, the multiple second unit molds 220 move closer to or further away from the first unit molds 210 along the centerline 630.

[0080] The number of the second unit dies 220 can be set according to the overall size of the concave die 200 and the edge shape of the bag-shaped area 600, for example, 2-6, etc. In an embodiment of the present application, a preferred mode is provided, i.e. two second unit dies 220 are symmetrically arranged on both sides of the center line 630, and the unit wall of each second unit die 220 is in the shape of a fold line, which matches the preset bag-shaped area 600. In combination with Figure 4a As shown by the arrow L, the position adjustment path of each second unit die 220 gradually moves away from the center line 630 from the bag opening side 610 to the bag bottom side 620. The position adjustment path of the second unit die 220 is arranged obliquely to the center line 630, for example, with an included angle of 30-60 degrees. Of course, in other embodiments, the second unit die 220 located on the bag bottom side 620 is also allowed to be adjusted along the direction of the center line 630.

[0081] During the position adjustment, each unit die can be automatically (configured with a power source such as a motor) and / or manually adjusted, and each unit die can be independently adjusted or multiple unit dies can be jointly adjusted, for example, all the first unit dies 210 are synchronously and reversely adjusted, or all the second unit dies 220 are jointly adjusted, or even all the unit dies are jointly adjusted. The joint position adjustment does not require that each participant has the same movement time and path trend.

[0082] In the direction of the center line 630, the first unit die 210 has a span H1, and the second unit die 220 has a total span H2. When multiple second unit dies 220 are arranged in the direction of the center line 630, the total span includes the interval between the second unit dies 220 in addition to the second unit dies 220 themselves. The span of each unit die is not the boundary of the structure and shape of the unit die, but should be referred to the position of the concave die wall matched with the bag-shaped plate.

[0083] The ratio of H1 to H2 is less than or equal to 30%, for example, the ratio of H1 to H2 is 10%-25%. According to the approximate proportional relationship, the second unit die 220 has a larger span ratio, which is more easily adapted to the adjustment of a larger range of the bag-shaped area 600, and can more reasonably distribute the interval of each unit die in the direction of the center line 630.

[0084] Referring to Figure 4b The edge of the bag-shaped area 600 includes the side edge 601 and the bottom edge 602 arranged in sequence from the bag opening side 610 to the bag bottom side 620. The division of the side edge 601 and the bottom edge 602 is mainly based on the included angle between the overall extension trend and the center line 630. The included angle between the side edge 601 and the center line 630 is smaller or even parallel, while the included angle between the bottom edge 602 and the center line 630 is larger, for example, greater than or equal to 45 degrees, or even perpendicular. The side edge 601 and the bottom edge 602 themselves can be straight lines, curved lines or fold lines without strict limitation.

[0085] Since the first unit die 210 plays a reference role of the bag mouth side 610, it is preferred that the span H1 of the first unit die 210 is less than or equal to 50% of the span of the side edge 601, for example, 10% to 30%, only at the end of the side edge 601 away from the bottom edge 602, for example, in the direction of the center line 630.

[0086] Since the position of the unit die is adjustable, that is, the shape of the bag-shaped area 600 is not unique, the above ratio can be understood as the ratio when the position of the unit die is adjusted to the minimum of the bag-shaped area 600.

[0087] The above ratio can also be applied to the folding knife assembly in other embodiments, wherein the span of the first unit die 210 corresponds to the span of the folding knife in the first folding knife assembly, and the total span of the second unit die 220 corresponds to the total span of the folding knife in the second folding knife assembly. Similarly, the span of the folding knife is understood as the span of the side of the folding knife that acts on the bag-shaped cloth, which is roughly parallel to the edge of the corresponding part of the bag-shaped area 600.

[0088] Based on the bag attaching machine concave die device of the present application, one embodiment further provides a bag attaching machine, which comprises a base plate 100 and a concave die device and a plurality of folding knife assemblies 300 mounted on the base plate 100, the concave die device and the plurality of folding knife assemblies 300 cooperate to fold the edges of the bag-shaped cloth, wherein each unit die and each folding knife assembly 300 is adjustable relative to the position of the base plate 100. The base plate 100, as the mounting platform of other components, has a relatively top side and a bottom side, the concave die 200 is at the bottom side of the base plate 100, and each unit die in the concave die 200 is slidably and positionally mounted on the base plate 100.

[0089] In order to adjust each second unit die 220, different transmission forms such as cams, connecting rods, and gears can be used. As preferred, in one embodiment of the present application, the bag attaching machine concave die device is further provided with a first lead screw mechanism 400, which is mounted on the top side of the base plate 100 and drives each second unit die 220 to adjust the position in a corresponding transmission manner, which can improve the adjustment efficiency and synchronicity.

[0090] The first lead screw mechanism 400 comprises a first motor 410 (a speed reducer can be configured according to needs), a shaft coupling 420, a first lead screw 430, and a nut seat 440 threadedly matched with the first lead screw 430, which are sequentially transmitted. The top side of the base plate 100 is fixed with a first support 110, which can include a plurality of support components to support the two ends of the first motor 410 and the first lead screw 430, respectively. The bottom of the nut seat 440 is fixed with a driving plate 450 that slides on the top side of the base plate 100, and is linked with each second unit die 220 through the driving plate 450. A guiding structure can be provided between the top side of the base plate 100 and the driving plate 450, for example, one has a guide rail and the other has a guiding seat matched with the guide rail, to guide the smooth movement of the driving plate 450.

[0091] To assist automatic control, the first detector 460 can be arranged to sense the position of the nut seat 440, and the corresponding feedback can control the second unit mold 220 to adjust the position. The extension direction of the first screw rod 430 is consistent with the center line 630, which can save height space. In the preferred embodiment, the vertical projection position of the first screw rod 430 corresponds to the position of the center line 630, which is more convenient for the symmetrical arrangement of the transmission mechanism.

[0092] Figure 6 As can be seen, the bottom side of the substrate 100 is slidingly mounted with the first adjusting seat 221 linked with the driving plate 450, and the second unit mold 220 is directly or indirectly fixed to the bottom of the first adjusting seat 221 through the connecting block 225. According to the expected position adjustment direction, the first adjusting seat 221 and the driving plate 450 can adopt a corresponding transmission mode. Since the driving plate 450 moves along the center line 630 with the nut seat 440, and the position adjustment direction of the second unit mold 220 is arranged obliquely to the center line 630, the transmission mode adopted in this embodiment is that a first hole 101 is arranged on the substrate 100, and a second hole 451 is arranged on the driving plate 450. The first hole 101 and the second hole 451 are arranged obliquely and have an overlapping area, the second hole 451 extends substantially along the direction perpendicular to the center line 630, and the extension direction of the first hole 101 corresponds to the position adjustment direction of the second unit mold 220. The first adjusting seat 221 is fixed with a first transmission member 224, which can be in the form of a transmission pin, for example, and sequentially passes through the first hole 101 and the second hole 451 upward. The first adjusting seat 221 and the second unit mold 220 are driven by the first transmission member 224 under the cooperation of the first hole 101 and the second hole 451.

[0093] To guide smoothly, the substrate 100 is provided with a guide rail 222 at the bottom, and the first adjusting seat 221 is provided with a sliding block 223 matched with the guide rail 222. Of course, the guide rail 222 and the sliding block 223 can also be interchanged in position.

[0094] The position-adjustable folding knife assembly 300 can adapt to the scaling of the die 200, and can be configured according to the position adjustment trend of the unit mold, for example, the folding knife assembly 300 comprises:

[0095] Two sets of first folding knife assemblies 310 are arranged on the bag opening side 610 and on both sides of the center line 630, respectively, and the position adjustment direction of each first folding knife assembly 310 is perpendicular to the center line 630.

[0096] A plurality of second folding knife assemblies 320 are arranged around the bag-shaped area 600 from the bag opening side 610 to the bag bottom side 620, and the position adjustment direction of each second folding knife assembly 320 is parallel or obliquely arranged to the center line 630.

[0097] The first folding knife assembly 310 includes a first folding knife cylinder 312 and a first folding knife 313 driven by the first folding knife cylinder 312. For example, the first folding knife 313 can be connected to the piston rod of the first folding knife cylinder 312 through a first connecting seat 314 and perform linear reciprocating motion.

[0098] Similarly, the second folding knife assembly 320 includes a second folding knife cylinder 321 and a second folding knife 326 driven by the second folding knife cylinder 321. For example, the second folding knife 326 can be connected to the piston rod of the second folding knife cylinder 321 through a second connecting seat 325 and perform linear reciprocating motion.

[0099] Referring to Figure 2 , the plurality of second folding knife assemblies 320 include a side edge folding knife assembly 3201 and a bag bottom folding knife assembly 3203 arranged in sequence from the bag opening side 610 to the bag bottom side 620. The side edge folding knife assembly 3201 has the same position adjustment direction as the second unit mold 220, and the position adjustment direction of the bag bottom folding knife assembly 3203 is parallel to the center line 630.

[0100] The second folding knife cylinder in the side edge folding knife assembly 3201 is mounted on the first adjustment seat 221 and moves synchronously with the second unit mold 220 during position adjustment.

[0101] The second folding knife cylinder 321 in the bag bottom folding knife assembly 3203 is located on the top side of the base plate 100 and mounted on the driving plate 450, Figure 5 As can be seen, the piston rod 322 of the second folding knife cylinder 321 is connected with a combination seat 323 extending to the bottom side of the base plate 100, the combination seat 323 is provided with a locking cylinder 324, and the second folding knife 326 is detachably inserted and fixed to the combination seat 323 through the second connecting seat 325 and is locked and positioned by the locking cylinder 324. The second connecting seat 325 can also be fixed to the combination seat 323 by other means such as screws.

[0102] Referring to Figure 7 , in order to more flexibly adjust the relative position of the second folding knife 326 and the combination seat 323, the combination seat 323 is provided with a sliding groove with an open bottom, the sliding groove is limited by a plug-in part 3231 locked by the locking cylinder 324, the plug-in part 3231 is provided with a plurality of gear holes, the second connecting seat 325 is provided with a slot and a fastener is arranged between each gear hole, when the fastener is loosened, the second connecting seat 325 is allowed to slide or adjust the gear relative to the combination seat 323.

[0103] In the bagging machine of the present application, in order to better adapt to the thickness or size changes of the bag-shaped cloth, simplify the structure of the equipment, the position adjustment of each knife assembly is linked with the position adjustment of each unit mold through mechanical structure or circuit control. For example, in one embodiment, the first knife assembly 310 and the first unit mold 210 have the same movement trend, so they are linked for position adjustment. When the second knife assembly 320 and the second unit mold 220 are adjusted, they are close to or away from each other, so they are also linked for position adjustment. The linkage position adjustment mode is mechanical transmission or action according to the coordinated control signal.

[0104] In order to meet the special folding requirements of the bag opening part, the knife assembly 300 can also include a bag opening knife assembly 330. The bag opening knife assembly 330 as a whole can be adjusted in position relative to the base plate 100 to adapt to the size changes of the bag-shaped cloth. The bag opening knife assembly 330 uses a rotary air cylinder, i.e., a bag opening knife air cylinder 331, and drives a reciprocating swing bag opening knife 332. For example, the top side of the base plate 100 is provided with a second support 120 and is correspondingly configured with a second screw rod mechanism 500. The second screw rod mechanism 500 includes a second motor 510 mounted on the second support 120, a second screw rod 520 linked with the second motor 510, and a pair of mounting seats 540 respectively threadedly fitted to the second screw rod 520. The bag opening knife assembly 330 is provided with two sets of mounting seats 540 respectively arranged in the corresponding mounting seats 540. The second support 120 is also fixed with a guide rod 530, and each mounting seat 540 is slidably sleeved on the guide rod 530 to limit the movement direction. In order to assist automatic control, a second detector 550 can be provided to sense the position of the mounting seat 540, and the position adjustment of the bag opening knife assembly 330 is correspondingly fed back and controlled. Since the second screw rod 520 is used for driving, the two sets of bag opening knife assemblies 330 move in opposite directions when they are adjusted in position, and have high adjustment accuracy.

[0105] Since the bag opening knife assembly 330, the first knife assembly 310, and the first unit mold 210 are adjacent in position and have the same position adjustment trend, any two or all of them can be independently adjusted in position or linked for position adjustment.

[0106] For example, when the bag opening knife assembly 330 and the first unit mold 210 are linked for position adjustment, it can also be understood that the second screw rod mechanism 500 also drives the two first unit molds 210 to be linked for position adjustment.

[0107] In order to hold the bag-shaped cloth with the bag-shaped plate, the side bottom of the base plate 100 is provided with a liftable abutment 700 (electromagnet) that can attract or release the bag-shaped plate through electromagnetic force.

[0108] In an embodiment of the present application, the top side of the base plate 100 is provided with a right-angle motor 710 to drive the bolster 700 to lift, wherein the extension direction of the right-angle motor 710 as a whole is consistent with the center line 630 and is below the first lead screw 430, which can optimize the spatial arrangement and reduce the interference with each other. The output shaft of the right-angle motor 710 is arranged vertically and points to the bottom side of the base plate 100 and is correspondingly linked with the bolster 700, for example, the threaded transmission can be used to convert the rotary motion of the output shaft into the lifting of the bolster 700. In order to guide the stable lifting of the bolster 700, the base plate 100 is provided with a guide hole, and the bolster 700 is fixed with a guide column 720 extending upward and slidingly fitted in the guide hole. In order to assist automatic control, a third detector 730 can be provided to sense the position of the guide column 720, and the corresponding feedback and control the lifting height of the bolster 700.
