Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bag opening machine structure, especially a bag opening machine with lifting type material placing table. BACKGROUND

[0002] In the garment processing process, the bag opening machine is an essential auxiliary processing machine, mainly used for forming a pocket at a specific position of the garment to facilitate carrying small items such as mobile phones and wallets. The traditional method is to separately process the bag mouth and the bag zipper, and then sew the bag lip or the zipper to the bag mouth to complete the bag opening.

[0003] Patent No. ZL202110846662.0, a bag opening machine for secondary sewing of a pocket, overcomes and breaks through the defects and technical bottlenecks of manual sewing of another pocket piece by using the bag opening machine to perform primary sewing and secondary sewing on two pocket pieces. The implementation of the bag opening machine relies on a lower supporting plate located below the pocket folding device.

[0004] Among them, patent No. ZL202022514163.5 discloses a continuous production garment bag opening machine, which uses an upper plate mechanism to position the lower supporting plate below the pocket folding device and to support the bag lip or the zipper. After the bag lip or the zipper is moved with the material positioning device and processed in the sewing device, the lower supporting plate is transferred to the lower side of the pocket folding device by the lower supporting plate resetting device, achieving timely resetting to facilitate the repositioning of the bag lip or the zipper for processing, realizing continuous processing and improving processing efficiency.

[0005] The specific structure of the lower supporting plate resetting device is described in patent No. ZL202022514165.4, which includes a pair of y-direction driving mechanisms and a set of x-direction driving mechanisms. The clamping mechanism is connected to the x-direction driving mechanism, which is connected to the workbench surface through a pair of y-direction driving mechanisms that can move synchronously. The material positioning device, also known as the pressure material shifting device, is guided by independent guide rails on the x-axis beam.

[0006] The workbench surface of the above-mentioned bag opening machine is in the same horizontal plane, and the large pressure frame of the material positioning device moves up and down on the workbench surface to take the material, which takes a long time to move. The lower supporting plate resetting device uses multiple linear rails or multiple modules to realize the resetting function through x-direction and y-direction movements, which is a great waste in terms of cost, structure, and movement mode.

[0032] The directional terms mentioned in this embodiment, such as "up," "down," "left," and "right," are merely used to help those skilled in the art understand the relationships between various features or parts in conjunction with the accompanying drawings.

[0033] like Figures 1 to 8 As shown, the worktable 17 of the bag opening machine is fixed on the frame 23 and is equipped with a sewing device a and a cutting device (not shown). The cutting device is a laser cutting device. The specific structure of the sewing device a and the cutting device is existing technology and will not be described in detail in this embodiment.

[0034] The bag folding device b includes several folding blades and is fixed on the crossbeam 21 of the bag opening machine. The number of folding blades can be two or four to handle the processing of the bag ends with loops or without loops. The processing without loops refers to the fact that the bag ends have triangles that need to be folded after cutting.

[0035] The material setting device c is slidingly arranged on the workbench 17, and comprises a large pressing frame c1 and a small pressing frame c2, and an upper plate mechanism c3 is arranged on the material setting device c; the large pressing frame c1 and the small pressing frame c2 are slidingly arranged on the workbench 17, and can be connected with the cross beam 21 of the bag opening machine, or the driving mechanism can be arranged at the bottom of the workbench 17 without being fixed to the upper cross beam; the upper plate mechanism c3 comprises a cylinder and a clamping block, and the clamping block is driven to fold to be clamped, or the clamping block is driven to swing up and down to be clamped;

[0036] The workbench 17 is provided with a lifting platform 1 which is arranged on the left side of the workbench 17 and below the bag folding device b, and is a position for placing the bag cloth to be sewn, and is located below the front part of the bag folding device b; in order to provide a lifting space for the lifting platform 1, an opening is formed in the corresponding position of the workbench 17, and the lifting platform 1 is installed in the opening and can be lifted and lowered;

[0037] The lifting platform 1 is provided with a supporting plate for placing the bag cloth and being clamped by the upper plate mechanism c3 of the material setting device c; the bag opening machine has two supporting plates during operation and work, which are a supporting plate A 18 and a supporting plate B 20, and the supporting plate A 18 and the supporting plate B 20 are cyclically clamped by the upper plate mechanism c3, so that the bag opening machine can be continuously operated or twice sewn.

[0038] The workbench 17 is provided with a circulating supporting plate driving device d for moving the supporting plate back and forth below the bag folding device b, and the circulating supporting plate driving device d comprises a clamping assembly d1 for clamping the supporting plate and a linear driving assembly 19 for driving the clamping assembly d1 to move back and forth; the clamping assembly d1 comprises a cylinder and a clamping block, and the clamping block is driven to fold to be clamped, or the clamping block is driven to swing up and down to clamp the supporting plate; the circulating supporting plate driving device d is used to remove the supporting plate participating in sewing from the material setting device c and timely release the supporting plate to the lifting platform 1. In the circulating process of the supporting plate, compared with the prior art, the horizontal movement of the supporting plate is omitted, and the structure of the bag opening machine is simplified.

[0039] In order to ensure the lifting flexibility and stability of the lifting platform, the lifting platform 1 is fixed on the rack 23 through the lifting guide rail assembly 6 and connected with the lifting cylinder 8; the specific fixing mode of the lifting platform 1 is that the left and right reinforcing plates 2 of the lifting platform and the reinforcing plate 3 of the lifting platform are fixed on the lifting platform surface 1, the reinforcing plate 3 of the lifting platform is fixed on the lifting platform connecting plate 7, the lifting platform connecting plate 7 is fixed on the lifting platform cylinder fixing plate 5 through the lifting guide rail assembly 6, the lifting platform cylinder fixing plate 5 is fixed on the rack 23 through the rear lifting plate support block 4, the front lifting platform cylinder fixing plate 11 is fixed on the rack 23, one end of the platform lifting driving block 10 is fixed on the reinforcing plate 3 of the lifting platform, and the other end is fixed on the head of the lifting cylinder 8, and the lifting cylinder 8 is fixed on the front lifting platform cylinder fixing plate 11 through the lifting cylinder fixing plate 9.

[0040] When the existing bag opening machine is in secondary sewing and forming of the pocket, the bottom bag cloth is under the large pressing frame of the material fixing device. When the large pressing frame of the material fixing device is lifted and the material is taken, two difficulties appear. One is that the bottom bag cloth will be lifted and wrinkled when it is pressed down. When the large pressing frame moves along the X or Y axis, the bottom bag cloth will be wrinkled, and the frequent wrinkling will cause the bottom bag cloth at the non-cuff position to be sewn on the cutting piece when the cuff line is sewn. The second is that when the large pressing frame moves to take the material, the bottom bag cloth fixed on the cutting piece will affect the position of the other placed bag cloth.

[0041] In view of the above problems, the utility model is provided with a small panel e above the lifting platform 1 on the workbench 17, the small panel e is connected with the small panel front and rear driving cylinder 12, after one-time sewing, the small panel e can support the bottom bag cloth which has been one-time sewn, so that it remains flat, when the bag cloth II for secondary sewing is lifted on the supporting plate and taken by the material fixing device c, the small panel front and rear driving cylinder 12 is used to drive and remove. In order to avoid the interference of the lifting action of the small panel e and the lifting platform 1, the small panel e can be relatively higher than the workbench 17, or the front and rear moving stroke of the small panel e can be increased, so that it is removed outside the lifting range of the lifting platform 1.

[0042] The specific fixing structure of the small panel e is that the small panel front and rear driving cylinder 12 is fixed on the rack 23 through the small panel cylinder fixing plate 13, and the small panel e is fixed on the head of the small panel front and rear driving cylinder 12 through the small panel driving plate 14.

[0043] In order to improve the moving stability of the small panel e, the reinforcing slide 15 is fixed on the workbench 17 in the front and rear directions, the small panel e is in sliding cooperation with the reinforcing slide 15, and the reinforcing slide 15 can also be replaced by a guide rail or a sliding rail.

[0044] Specifically, the clamping assembly d1 is arranged on the linear driving assembly 19 in a lifting mode by using a cylinder.

[0045] When the utility model works

[0046] Initial state: the material positioning device c is located on the right side of the garment processing station, the supporting plate B20 is located below the material positioning device c, the lifting cylinder 8 is in the retracted state, the small panel front and rear driving cylinder 12 is in the retracted state, and the supporting plate A18 is located on the lifting platform 1.

[0047] Motion state: when the material positioning device c moves to the position above the lifting platform 1 with the supporting plate B20 and the cutting piece (i.e. the once-sewn bag piece), the linear driving assembly 19 drives the clamping assembly d1 to move along the Y-axis to the front of the machine, and after clamping the supporting plate B20, it returns to the rear of the bag folding device b along the original path; the small panel front and rear driving cylinder 12 extends through the small panel driving plate 14 to drive the small panel e to move along the Y-axis direction, supporting the once-sewn bag piece to avoid wrinkles; the lifting cylinder 8 extends through the platform lifting driving block 10 and the lifting platform reinforcing plate 3 to drive the lifting platform 1 to move upward along the Z-axis to the horizontal plane of the workbench 17 or higher than the workbench 17, cooperating with the material positioning device c to take away the supporting plate A18 for sewing;

[0048] The lifting cylinder 8 retracts through the platform lifting driving block 10 and the lifting platform reinforcing plate 3 to drive the lifting platform 1 to move downward along the Z-axis, so that the lifting platform 1 is lower than the workbench 17, the linear driving assembly 19 drives to move along the Y-axis to the front of the machine, and the lifting of the clamping assembly d1 is combined to send the supporting plate B20 to the position of the lifting platform 1 for fixation.

[0049] The above embodiments are illustrative of the present application, but not limiting of the present application, and any simple transformation of the present application belongs to the protection scope of the present application.
