Description

Technical Field

[0001] The utility model relates to the technical field of non-woven bag making machines, in particular to a non-woven drawstring bag making machine, and in particular to a double-layer threading and closing device of the non-woven drawstring bag making machine. Background Art

[0002] The non-woven drawstring bag making machine produces non-woven drawstring bags by automatically folding, threading, breaking and cutting non-woven fabrics. The non-woven drawstring bags have the advantages of being reusable, non-absorbent and mold-proof, breathable and easy to clean, and the drawstring design of the non-woven bags makes it difficult for items in the bag to fall out. They are widely used in life for marinade, tea, etc.

[0003] Some non-woven drawstring bag making machines, such as the patent with application number CN202311755908.9, provide a non-woven bag making machine with automatic rope threading, including a frame, a loading device, a folding device, a compacting mechanism, a folding device, a punching device, an automatic rope threading device, a rope cutting device, and a bag dividing device installed on the frame in sequence. The automatic rope threading device includes a spreading mechanism, a traction cylinder assembly and an edge sealing mechanism. In order to facilitate the adjustment of the positional relationship between the traction cylinder in the traction cylinder assembly and the welding seat and the rotating welding head in the edge sealing mechanism, the traction cylinder is slidably installed and can be limited by screws, and the welding seat and the rotating welding head are independently connected with slide rails and screw rods.

[0004] However, the expansion mechanism, traction cylinder assembly and edge sealing mechanism are directly installed on the frame, so that the bag making machine is assembled based on the frame, and the space for installing the automatic rope threading device on the bag making machine is limited, resulting in a limit on the number of assemblers who can participate in the assembly of the automatic rope threading device on the frame, and the assembly efficiency cannot be improved.

[0005] At the same time, the traction tube, welding seat and rotating welding head can all be slid and adjusted on the frame. When the drawstring in the folding position of the non-woven fabric and the position of the non-woven fabric change, the positions of the traction tube, welding seat and rotating welding head need to be adjusted and corrected. The adjustment of variable correction can easily increase the difficulty of correction and the correction operation is more troublesome. Utility Model Content

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0031] This embodiment mainly describes a double-layer threading and fastening device for a non-woven drawstring bag making machine that can effectively improve assembly efficiency and reduce the difficulty of position calibration. The details are as follows:

[0032] like Figure 1-7 As shown, the double-layer threading and closing device of the non-woven drawstring bag making machine includes a frame 1 and a mounting frame 2 slidably mounted on the frame 1. The mounting frame 2 is detachable and divided into a bottom plate 2a, a layer plate 2b, a top plate 2c and a side plate 2d. The bottom plate 2a, the layer plate 2b and the top plate 2c are distributed in sequence from bottom to top. The side plate 2d is arranged on both sides of the layer plate 2b and is fixedly connected to the bottom plate 2a, the layer plate 2b and the top plate 2c. Preferably, the fixed connection between the bottom plate 2a, the layer plate 2b, the top plate 2c and the side plate 2d can be achieved by screw thread connection or welding.

[0033] A cylinder 3 is fixed on each of the bottom plate 2a and the top plate 2c, and the driving rod of the cylinder 3 is connected to the welding seat 4. The welding seat 4 is located above the bottom plate 2a or below the top plate 2c, and the welding seat 4 is located on the outside of the layer plate 2b. In this embodiment, a group of two mounting seats 5 are fixed on the layer plate 2b, and a rotating shaft 6 is rotatably installed on a group of mounting seats 5. A welding head 7 is installed at one end of the rotating shaft 6, and the welding head 7 corresponds to the welding seat 4 one-to-one, and the cylinder 3 can adjust the distance between the welding seat 4 and the welding head 7. A driven wheel 8 is installed at the other end, and a rear plate 2e is installed on each of the two side plates 2d, and a motor 9 is fixed on the rear plate 2e. A driving wheel 10 is installed on the motor 9 shaft of the motor 9, and a belt 11 that links the two is installed on the driving wheel 10 and the driven wheel 8, and a guide block 12 is installed on each of the side plates 2d and the layer plate 2b, and a wire barrel 13 is plugged and installed on the guide block 12.

[0034] Preferably, the driven wheel 8 and the driving wheel 10 can be meshed with each other, or the motor 9 shaft of the motor 9 can directly drive the rotating shaft 6 to rotate.

[0035] In this application, through the setting of the mounting frame 2, the welding seat 4, welding head 7, motor 9 and wire tube 13 on the mounting frame 2 can be installed in an independent modular assembly. The number of assemblers is not limited by the size of the mounting frame 2, which can effectively improve the assembly efficiency.

[0036] In order to facilitate the adjustment of the tightness of the belt 11, the rear plate 2e is slidably installed on the side plate 2d, that is, a slide groove is provided on the side plate 2d, and the rear plate 2e is slidably connected to the slide groove by a bolt (the bolt is not shown in the drawings of the specification), and the rear plate 2e is limited by the nut of the bolt and the side plate 2d.

[0037] like Figure 1-7 As shown, a guide rail 14 is installed above the frame 1, and a slider 15 is installed below the bottom plate 2a. The slider 15 is slidably connected to the guide rail 14, that is, the sliding setting of the mounting frame 2 on the frame 1 is realized, and a screw block 16 is fixed on each of the side plates 2d of the frame 1 and the mounting frame 2, and a screw rod 17 is provided to threadably connect the two screw blocks 16, which can limit the sliding of the mounting frame 2 on the frame 1.

[0038] In order to facilitate the rotation of the screw rod 17 around the axis of the thread, that is, to adjust the sliding position of the mounting bracket 2 on the frame 1, an operating hand wheel 18 is provided at one end of the screw rod 17.

[0039] The wire barrel 13 inserted into the guide block 12 is slidably inserted, and a screw is threadedly connected to the guide block 12 (the screw is not shown in the drawings of the specification). The screw can resist the wire barrel 13 and limit the sliding of the wire barrel 13 on the guide block 12.

[0040] In this application, by only adjusting the position of the mounting frame 2 and the wire tube 13, the adjustment variables of the welding seat 4, welding head 7 and wire tube 13 corresponding to threading and welding inside the folded edge of the non-woven fabric are reduced, effectively reducing the difficulty of proofreading during position adjustment and simplifying the proofreading operation.

[0041] In this embodiment, the cylinder 3 is connected to a mounting plate 19, on which are provided four guide rods 20 that are slidably plugged into the top plate 2c or the bottom plate 2a. The mounting plate 19 is located between the layer plate 2b and the top plate 2c or the bottom plate 2a. The welding seat 4 is fixed on the mounting plate 19, and the cylinder 3 drives the welding seat 4 to rise or fall through the mounting plate 19.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use.
