Description

Technical Field

[0001] This utility model relates to the field of bag opening machine equipment, and in particular to a material setting mechanism for a bag forming machine. Background Technology

[0002] There are various types of pockets on clothing, including slip pockets, patch pockets, double-stitched pockets, and single-stitched pockets. To reduce labor costs and improve the efficiency of opening pockets in clothing, pocket opening machines are essential auxiliary processing machinery in the garment manufacturing process. They are mainly used to create pockets in specific locations on clothing, making it convenient to carry small items such as mobile phones and wallets. The traditional method is to first open the pocket opening and the pocket lip or a pocket lip with a pocket lining separately, and then sew the pocket lip or the pocket lip with the pocket lining onto the pocket opening to complete the pocket opening process. The pocket lining consists of two pieces of pocket lining. When only the pocket lip is sewn on, it is a false pocket; when the pocket lip with the pocket lining is sewn on, it is a true pocket.

[0003] The processing technology of the existing bag opening machine is as follows: First, the inner pressure frame of the material setting mechanism closes to the outer pressure frame to position the bag opening of the garment. Then, the laser head of the laser cutting device cuts the bag opening. After the cutting is completed, the material setting mechanism moves to the upper part of the lower support plate on which the bag lip with the bag fabric piece is placed, and the bag folding mechanism performs the bag folding process. Then, the material setting mechanism presses down so that the bag opening of the garment is stacked on the bag lip. Finally, it moves to the sewing station for sewing.

[0004] I previously filed a Chinese invention patent application (patent number 202411492215.X) entitled "An Automated Garment Pocket Forming Machine." In this design, the material fixing mechanism and the folding mechanism cooperate to fix the folded edge of the pocket fabric piece, facilitating the subsequent sewing of the formed accessories onto the pocket fabric piece via a sewing machine head. Regarding the fixing of the pocket fabric piece by the material fixing mechanism, the above design uses three sets of pressing components working together. The two sets of pressing components above the material fixing plate fix the pocket fabric piece in the material fixing opening of the plate. The folding mechanism's folding blade has a bending head at its lower end, which completes the folding process by pressing down on the edge of the processing opening. The third pressing component then fixes the folded edge. However, in practical applications, this design has certain limitations and cannot be applied to the folding action of processing openings on all pocket fabric pieces. For example, many pocket fabric panels currently on the market have small triangles cut out at both ends of the processing opening. These triangles are folded inwards and sewn to the lining. This hides the seams at both ends of the processing opening, making it more aesthetically pleasing. Obviously, the original technology cannot automate this process well, requiring manual cutting and folding of the triangles, which is very cumbersome. Alternatively, the triangles are omitted altogether, and the seams are directly sewn at both ends of the processing opening (which is less aesthetically pleasing). In addition, with existing technology, adjusting the size of the pocket often requires changing the mold, which is also cumbersome. Utility Model Content

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0054] Furthermore, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0055] Detailed implementation plan: See below Figures 1-15 This utility model relates to a material setting mechanism for a pocket forming machine, which is mounted on a sliding frame. The sliding frame is equipped with a first driving device that works in conjunction with a driving mounting plate to lift and lower, comprising:

[0056] The material plate 1 is fixed to the mounting plate by a connecting block, and the material plate 1 is provided with a material opening for placing pocket fabric pieces;

[0057] Several pressing components are installed on the fixed material plate 1 or the mounting plate to cooperate in fixing the pocket fabric piece, which has a processing opening;

[0058] Several material pulling components are installed on the fixed material plate 1, and each includes a drive source and a material pulling plate linked to the drive source. The material pulling plate is arranged below the pocket fabric piece, and the material pulling plate is provided with a strip-shaped opening. The material pulling has a waiting-to-pull state and a pulling state. In the waiting-to-pull state, each strip-shaped opening is respectively arranged on each edge of the processing opening. The edge of the processing opening is pushed into the strip-shaped opening by the insert knife. In the pulling state, the several material pulling plates are all driven by their respective drive sources to move to the side away from the processing opening, and fold and fix the edge of the processing opening.

[0059] Note that the material-setting mechanism in this embodiment is intended to replace the material-setting mechanism installed in the automated garment pocket forming machine disclosed in Chinese Invention Patent No. 202411492215.X. Therefore, the sliding frame and the first driving device mentioned above are prior art and will not be discussed further in this document.

[0060] Please see Figure 4 In this embodiment, it can be seen that the front pull plate 62, the rear pull plate 72 and the side pull plate 82 are all located below the fixed plate 1.

[0061] In this embodiment, the insert of the bag folding mechanism needs to pass through the strip opening, so it needs to be designed as a sheet-shaped insert. That is, there is no need to set a bending head at the lower end of the insert. The sheet-shaped insert can be used to press the edge of the processing opening downward into the strip opening.

[0062] Then, please see Figures 1-4 As can be seen, in this embodiment, there are four material pulling components, namely the first material pulling component 6, the second material pulling component 7, and two third material pulling components 8. The driving source of the first material pulling component 6 is the fourth cylinder 61, the material pulling plate is the front pulling plate 62, and the strip opening is the first strip opening 621. The driving source of the second material pulling component 7 is the fifth cylinder 71, the material pulling plate is the rear pulling plate 72, and the strip opening is the second strip opening 721. The driving source of the third material pulling component 8 is the sixth cylinder 81, the material pulling plate is the side pulling plate 82, and the strip opening is the third strip opening 821.

[0063] Next, in this embodiment, the fourth cylinder 61 is used to drive the front pull plate 62 to translate in the front-back direction, and the first strip opening 621 extends in the left-right direction; the fifth cylinder 71 is used to drive the rear pull plate 72 to translate in the front-back direction, and the second strip opening 721 extends in the left-right direction, with the first strip opening 621 arranged in front of the second strip opening 721; the sixth cylinder 81 is used to drive the side pull plate 82 to translate in the left-right direction, and the third strip opening 821 extends in the front-back direction.

[0064] Note that in this embodiment, there are two fourth cylinders 61 located in the first material pulling assembly 6 and two fifth cylinders 71 located in the second positioning assembly 9. The two fourth cylinders 61 work together to drive the front pulling plate 62 to move back and forth more smoothly, and the two fifth cylinders 71 work together to drive the rear pulling plate 72 to move back and forth more smoothly.

[0065] Furthermore, when it is necessary to fold and fix the edge of the processing opening that is pushed into the strip opening by the insert cutter, the combined front-to-back pulling action of the first material pulling component 6 and the second material pulling component 7 constitutes one action, and the combined left-to-right pulling action of the two third material pulling components 8 constitutes one action. In order to better fold the small triangles located at the left and right ends of the processing opening, in this embodiment, the above two actions need to be performed separately, one after the other.

[0066] The working principle of the first material pulling assembly 6 is explained below:

[0067] When the front edge of the processing port is pushed downward into the first strip opening 621 by the inserter, the inserter retracts upward, and the fourth cylinder 61 drives the front pull plate 62 to move forward. Since part of the pocket fabric remains fixed in the fixed material opening, the rear inner wall of the first strip opening 621 will squeeze the front edge of the processing port and fold and fix the edge.

[0068] Similarly, the second material pulling component 7 is used to fold and fix the rear edge of the processing opening, and the third material pulling component 8 is used to fold and fix the left and right edges of the processing opening.

[0069] Please see Figure 6 , Figure 14 and Figure 15 The material-setting plate 1 is provided with two third guide grooves 13 extending in the left-right direction. The material-setting mechanism also includes an adjustment component 9, which includes:

[0070] The seventh cylinder 91 is fixed on the fixed plate 1;

[0071] The adjustment plate 92 is linked to the seventh cylinder 91, which is used to drive the adjustment plate 92 to move horizontally in the left and right directions.

[0072] The second side support plate 93 is connected to one side of the adjustment plate 92 and is slidably disposed on the third guide groove 13. The second side support plate 93 is provided with an adjustment port 931 extending in the left and right direction.

[0073] A first side support plate 83 is provided on one side of the side pull plate 82, and an upper connecting block 831 adapted to slide in the adjustment port 931 is provided at the upper end of the first side support plate 83.

[0074] In addition, in this embodiment, the material plate 1 is provided with a notch 131 for the upper receiving block 831 to pass through. The notch 131 extends in the left and right direction and corresponds to the upper and lower positions of the adjustment port 931.

[0075] The working principle of the adjustment component 9: When it is necessary to adjust the starting pull position of the side pull plate 82 in the left and right direction, the seventh cylinder 91 works and drives the adjustment plate 92 to move left and right. Since the second side support plate 93 is connected to one side of the adjustment plate 92, the second side support plate 93 can follow the adjustment plate 92 to move left and right. At this time, the position of the adjustment port 931 set on the second side support plate 93 will also move left and right. Since the first side support plate 83 is connected to one side of the side pull plate 82, and the upper end of the first side support plate 83 is provided with an upper connecting block 831 that is adapted to slide in the adjustment port 931, when the position of the adjustment port 931 is adjusted, the translation path of the upper connecting block 831 will also be adjusted, thereby completing the adjustment of the starting pull position of the side pull plate 82 in the left and right direction.

[0076] Note that in this embodiment, by setting an adjustment component on the fixed material plate 1, when it is necessary to adjust the size of the pocket, there is no need to change the mold. It is only necessary to adjust the starting pulling position of the side pull plate 82 by adjusting the adjustment component 9, which is very labor-saving and convenient.

[0077] Then, please see Figure 1 , Figure 2 , Figure 11 , Figure 12 and Figure 13 In this embodiment, there are two pressing components, namely a first pressing component 4 and a second pressing component 5, wherein the first pressing component 4 includes:

[0078] The lifting plate 41 is linked to a second drive device arranged on the mounting plate. The second drive device is used to drive the lifting plate 41 to rise and fall.

[0079] The large pressure frame 42 is located on one side of the lifting plate 41;

[0080] The front pressure strip 43 is fixed on the large pressure frame 42.

[0081] The working principle of the first pressing component 4: After the pocket fabric is placed in the fixed material opening, the second driving device drives the lifting plate 41 to descend, and causes the front pressing strip 43 fixed on the large pressing frame 42 to press down on the front end of the pocket fabric.

[0082] The second pressing assembly 5 includes:

[0083] Fixing plate 51 is fixed above the material fixing plate 1;

[0084] The third cylinder 52 is mounted on the fixed plate 51 and is used to drive the lifting block 53 to rise and fall.

[0085] The rear pressure bar 54 is fixed on the lifting block 53;

[0086] The front seam strip 43 is positioned in front of the rear seam strip 54 and works together with the rear seam strip 54 to secure the pocket fabric.

[0087] The working principle of the second pressing component 5: After the pocket fabric is placed in the fixed material opening, the third cylinder 52 drives the lifting block 53 to descend, and causes the rear pressure strip 54 fixed on the lifting block 53 to press down on the rear end of the pocket fabric.

[0088] Next, please refer to Figure 3 , Figures 7-10 As can be seen, the material setting mechanism also includes a front shaping component 2 and a rear shaping component 3 for adjusting the size of the material setting opening. The front shaping component 2 includes a first cylinder 21 and a first sliding plate 22. The first cylinder 21 is used to drive the first sliding plate 22 to move horizontally in the front-back direction. A front shaping plate 23 is fixed on the first sliding plate 22. The rear shaping component 3 includes a second cylinder 31 and a second sliding plate 32. The second cylinder 31 is used to drive the second sliding plate 32 to move horizontally in the front-back direction. A rear shaping plate 33 is fixed on the second sliding plate 32. The front shaping plate 23 is arranged in front of the rear shaping plate 33, and the material setting opening is formed between the front shaping plate 23 and the rear shaping plate 33.

[0089] Working principle of front shaping component 2 and rear shaping component 3:

[0090] When it is necessary to adjust the size of the feed inlet, the first cylinder 21 drives the first sliding plate 22 to move back and forth, and the second cylinder 31 drives the second sliding plate 32 to move back and forth. Since the front shaping plate 23 is fixed on the first sliding plate 22 and the rear shaping plate 33 is fixed on the second sliding plate 32, the front-to-back distance between the front shaping plate 23 and the rear shaping plate 33 can be adjusted.

[0091] For more details, please see Figure 3 , Figures 6-10 As can be seen, in this embodiment, the first sliding plate 22 is provided with two first sliding bars 221, one end of which is linked to the first cylinder 21; the second sliding plate 32 is provided with two second sliding bars 321, one end of which is linked to the second cylinder 31; the fixed plate 1 is provided with a first guide groove 11 for the first sliding bar 221 to be slidably installed, and a second guide groove 12 for the second sliding bar 321 to be slidably installed.

[0092] Here, the design of the first guide groove 11 and the second guide groove 12 allows the first sliding plate 22 and the second sliding plate 32 to move more smoothly in the front-back direction after being driven.

[0093] Furthermore, in this embodiment, a first protrusion 111 is provided on the extension path of the first guide groove 11, and a first guide opening 222 for placing the first protrusion 111 is provided on the first slide bar 221, with the first guide opening 222 extending in the front-back direction; a second protrusion 121 is provided on the extension path of the second guide groove 12, and a second guide opening for placing the second protrusion 121 is provided on the second slide bar 321, with the second guide opening extending in the front-back direction.

[0094] Here, the design of the first guide opening 222 and the first protrusion 111 limits the forward and backward sliding distance of the first sliding plate 22; the design of the second guide opening and the second protrusion 121 limits the forward and backward sliding distance of the second sliding plate 32. Furthermore, in this embodiment, both the first and second protrusions are column screws, which prevent the first sliding plate 22 and the second sliding plate 32 from tilting upwards during forward and backward translation, thus making the translation smoother.

[0095] In addition, please see Figure 8 As can be seen in this embodiment, the lower end surface of the front shaping plate 23 is provided with a plurality of first countersunk holes 231 for the installation of the first magnetic block. Since the front pull plate 62 is located below the first magnetic block and the front pull plate 62 is made of ferromagnetic material, the first magnetic block will attract the front pull plate 62 upward, thereby preventing the front pull plate 62 from bending downward and ensuring that the front pull plate 62 can move smoothly and steadily back and forth under the drive of the fourth cylinder 61.

[0096] Please see Figure 10As can be seen in this embodiment, the lower end surface of the rear shaping plate 33 is provided with a plurality of second countersunk holes 331 for mounting the second magnet. Since the rear pull plate 72 is located below the second magnet and the rear pull plate 72 is made of ferromagnetic material, the second magnet will attract the rear pull plate 72 upward, thereby preventing the rear pull plate 72 from bending downward and ensuring that the rear pull plate 72 can move smoothly back and forth under the drive of the fifth cylinder 71.

[0097] The material setting mechanism of the pocket forming machine of this utility model described above is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
