Description

Technical Field

[0001] This utility model relates to the field of sponge processing, and in particular to a sewing device for a sponge inner sleeve bagging machine. Background Technology

[0002] In the existing sponge production process, during the storage, packaging, and transportation of finished sponges, the sponge itself inevitably has a certain degree of stickiness due to the limitations of its material. Therefore, multiple sponges cannot be directly stacked for storage, otherwise, prolonged contact will easily cause adjacent sponges to stick together. Separating the sponges in subsequent operations is troublesome and can easily damage them. To address this, a gauze bag is placed on the outside of the sponge as an inner sleeve to prevent this phenomenon. However, the traditional bagging method is done manually, and the size of the existing gauze bags is not matched one-to-one with the size of the sponge. Instead, yarn tubes, which are several tens of meters long, are cut and sewn to match the sponge's size. All of these processes are done manually, requiring a large amount of manual labor, resulting in high labor intensity and low work efficiency.

[0003] Patent CN212922204U proposes an overlock sewing system for a sponge inner bagging machine, comprising a first cutting and overlock sewing assembly and a second cutting and overlock sewing assembly arranged in parallel along the sponge conveying direction; the first cutting and overlock sewing assembly includes a first cutting and overlock sewing bracket, a yarn tube combing mechanism, a first overlock sewing machine, a first cutting machine, and a third horizontal moving mechanism; the second cutting and overlock sewing assembly includes a second cutting and overlock sewing bracket, a second overlock sewing machine, a second cutting machine, and a fourth horizontal moving mechanism.

[0004] In the aforementioned patent, the stitching and cutting of the inner sleeve is achieved through the combined action of a first and a second cutting and stitching assembly. This structure is complex, and the coordination between the two sets of cutting and stitching assemblies is also a significant hurdle. Furthermore, because it uses two sets of cutting and stitching assemblies, a gap is left between them to prevent interference during operation. This inevitably leads to waste material being generated during the cutting of the inner sleeve, increasing the cost of the inner sleeve. Moreover, due to the waste material, a waste collection mechanism is required to collect and process it uniformly, preventing waste accumulation and ensuring a clean production environment for the entire sponge bag. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple and convenient overlock sewing device for a sponge inner sleeve bagging machine that is easy to overlock and cut.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sewing device for a sponge inner sleeve bagging machine, the innovation of which is: including A sewing cutter support, comprising a fixed support and a movable support, the movable support being able to move horizontally along the fixed support; A sewing and cutting unit mounted on a movable support, the sewing and cutting unit comprising a sewing component and a cutting component; The overlock assembly includes an overlock machine and an overlock pad. The overlock pad is mounted on a movable support. The overlock machine has two sets of synchronously operating needle groups. The two sets of needle groups are arranged side by side along the conveying direction of the sponge inner sleeve. Each set of needle groups consists of several needles arranged side by side along the conveying direction of the sponge inner sleeve. The overlock pad also has sewing holes that correspond one-to-one with each needle. The cutting assembly includes a cutting blade and a cutting pad. The cutting pad is fixed to a sewing pad. The cutting blade is located above the cutting pad and is driven to rotate by a cutting motor mounted on a movable bracket. A cutting slit is also opened on the cutting pad to avoid the cutting blade. Two sets of sewing needles are located on both sides of the cutting blade.

[0007] Furthermore, an arc-shaped protective cover is provided on the upper side of the cutting blade.

[0008] Furthermore, the fixed support includes a pair of uprights and several crossbars connected between the two uprights. A horizontal guide rail is also installed on the fixed support, and the horizontal guide rail extends along the horizontal movement direction of the movable support. A horizontal slider that cooperates with the horizontal guide rail is also installed on the side end of the movable support. The movable support moves horizontally along the horizontal guide rail by the cooperation of a synchronous belt and a synchronous pulley.

[0009] Furthermore, a lower limiting plate is provided at the bottom of the movable support, and a pair of limiting crossbars are provided between the two uprights of the fixed support, with a gap between the two limiting crossbars. The lower limiting plate is located below the limiting crossbars.

[0010] Furthermore, the cutting pad is provided with an inclined guide section on the side away from the overlock pad, and the inclination direction of the guide section is gradually downward from the side where the guide section is connected to the cutting pad.

[0011] The advantages of this utility model are as follows: The overlock sewing device of this utility model uses two sets of sewing needles and a cutting blade located between the two sets of sewing needles to achieve the overlock sewing and cutting of the inner sleeve. Only one set of overlock sewing and cutting unit is needed, which simplifies the structure. Moreover, this cutting method avoids the generation of intermediate waste, so there is no need to equip a waste collection mechanism, thus reducing costs.

[0012] By using the lower limit plate at the bottom of the movable support and the limit crossbar on the fixed support, the relative position of the movable support and the fixed support is restricted when the movable support moves horizontally, thus preventing the movable support from moving upward or running.

[0013] The guide section on one side of the cutting mat and overlock mat is used to guide the inner sleeve, ensuring that the inner sleeve can be smoothly laid on the cutting mat and overlock mat during overlocking and cutting.

[0014] The protective cover is designed to protect the cutting blade and prevent solid impurities from falling onto it and damaging it. Attached Figure Description

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] like Figures 1-6The illustrated overlock sewing device for a sponge inner sleeve bagging machine includes... A sewing cutting support includes a fixed support 1 and a movable support 2, which moves horizontally along the fixed support 1.

[0023] The fixed support 1 includes a pair of uprights 11 and several horizontal supports 12 connected between the two uprights 11. Horizontal guide rails 13 are also installed on the fixed support 1. There are four horizontal guide rails 13 in total, which are distributed vertically on the fixed support 1 and extend along the horizontal movement direction of the movable support 2. Horizontal sliders that cooperate with the horizontal guide rails 13 are also installed on the side of the movable support 2. The movable support 2 moves horizontally along the horizontal guide rails 13 by the cooperation of the synchronous belt 14 and the synchronous pulley. The synchronous pulley is driven to rotate by the drive motor 15 installed on the fixed support 1. The synchronous belt 14 is connected to the movable support 2, so that when the synchronous pulley drives the synchronous belt 14 to move, it drives the movable support 2 to move horizontally.

[0024] A lower limiting plate 22 is also provided at the bottom of the movable support 2. The lower limiting plate 22 is a horizontal plate. At the same time, a pair of limiting crossbars 16 are provided between the two uprights 11 of the fixed support 1. The two sides of the limiting crossbars 16 are welded to the two uprights 11 respectively, and a gap is left between the two limiting crossbars 16. The lower limiting plate 22 is located below the limiting crossbars 16. The movable support 2 and the lower limiting plate 22 are connected by a pair of vertical connecting plates 21, and the two connecting plates 21 pass through the gap between the two limiting crossbars 16. Through the cooperation of the lower limiting plate at the bottom of the movable support 2 and the limiting crossbars 16 on the fixed support 1, the relative position of the movable support 2 and the fixed support 1 is limited when the movable support 2 moves horizontally, so as to prevent the movable support 2 from moving upward or running.

[0025] The overlock cutting unit is mounted on the movable support 2. The overlock cutting unit includes an overlock component and a cutting component.

[0026] The overlock assembly includes an overlock machine 23 and an overlock pad 24. The overlock pad is mounted on the movable bracket 2. The overlock machine 23 has two sets of synchronously operating needle groups. The two sets of needle groups are arranged side by side along the conveying direction of the sponge inner sleeve. Each set of needle groups consists of several needles 25 arranged side by side along the conveying direction of the sponge inner sleeve. There is a gap between the two sets of needle groups. The overlock pad 24 also has sewing holes that correspond one-to-one with each needle 25.

[0027] The cutting assembly includes a cutting blade 26 and a cutting pad 27. The cutting pad 27 is fixed to the overlock pad 24. The cutting blade 26 is vertically positioned above the cutting pad 27 and is driven to rotate by a cutting motor 262 mounted on the movable bracket 2. A cutting slit 28 is provided on the cutting pad 27 to allow the cutting blade 26 sufficient downward space to cut the inner sleeve. Two sets of sewing needles are located on either side of the cutting blade 26. Figure 6 As shown.

[0028] An inclined guide section 271 is provided on both the side of the cutting pad 27 away from the overlock pad 24 and the side of the overlock pad 24 away from the cutting pad 27. The guide section 271 connected to the cutting pad 27 is inclined downwards from the side where it is connected to the cutting pad 27, and the guide section 271 connected to the overlock pad 24 is inclined downwards from the side where it is connected to the overlock pad 24. The guide section 271 on the side of the cutting pad 27 and the overlock pad 24 is used to guide the inner sleeve, ensuring that the inner sleeve can be smoothly laid on the cutting pad 27 and the overlock pad 24 during overlocking and cutting.

[0029] An arc-shaped protective cover 261 is also provided on the upper side of the cutting blade 26. The protective cover 261 is designed to protect the cutting blade 26 and prevent solid impurities from falling onto the cutting blade 26 and causing damage.

[0030] When using the overlock sewing device of this utility model to overlock and cut the sponge inner sleeve, the movable support 2 first moves horizontally along the fixed support 1. After the overlocked and cut sponge inner sleeve is guided by the guide section 271, it is laid flat on the cutting pad 27 and the overlock pad 24. As the movable support 2 moves, two sets of sewing needles are used to overlock the tail of the previous sponge inner sleeve and the front of the next sponge inner sleeve respectively. After overlocking, the cutting blade 26 between the two sets of sewing needles is used to cut the entire inner sleeve, separating the tail of the previous sponge inner sleeve from the front of the next sponge inner sleeve. This process is repeated to insert the sponge into the inner sleeve, which is sealed on both the front and back sides.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
