[0043] The electric trolley 12 contains a first working position at the pushing end position of the pushing cylinder 3 through the sliding of the sliding rail 11, and a second working position 17 away from the first working position.

[0044] Above the second working position 17 on the workbench 2, a laser cutting head 18 is arranged through a laser support. The number of elastic guide structures is two.

The way of the hot module assembly 10 to heat and press the cloth, and the technical means of the laser cutting head 18 to cut the cloth are both common implementation manners in the prior art. Specifically, the hot module assembly combines the cloth and the hot melt glue bag strip through heating and pressing to achieve the effect of hot-pressing forming. This process usually relies on temperature control and pressure adjustment of the hot module to ensure the best combination effect within a proper time. The laser cutting head uses high energy density of laser beam to accurately cut the cloth. By adjusting the power and moving speed of the laser, high-precision cutting contour can be achieved. These technical methods have been widely applied in the related field and have mature technical foundation and good operation stability, which all belong to the extension implementation manners known by the ordinary skilled in the art.

[0047] The cloth positioning clamp plate 16 comprises a first plate body 28 and a second plate body 29, and a space for clamping the cloth is formed between the first plate body 28 and the second plate body 29. The cloth positioning clamp plate 16 is provided with a cloth processing avoidance notch 30. The front ends of the first plate body 28 and the second plate body 29 are hingedly connected. The cloth positioning clamp plate 16 is made of transparent material.

[0048] In addition, the electric trolley 12 mentioned in the embodiment realizes the electric sliding mode, the pneumatic control of each cylinder, the negative pressure adsorption of the negative pressure suction cup 7, and the automatic starting mode of each component, which all belong to the extended embodiments known to those skilled in the art. Specifically, the electric trolley can be driven by a motor to move smoothly, and the control of the cylinder can be adjusted by a standard pneumatic system to ensure smooth cooperation between each process. In addition, the adsorption mechanism of the negative pressure suction cup adopts conventional negative pressure control technology, which can effectively ensure the stable grabbing and releasing of the hot melt adhesive bag strip. The automation of each component can be programmed using a control system such as a PLC (Programmable Logic Controller) to achieve efficient production processes and operational convenience. Since these technical means are conventional in the art, they will not be described here.

[0049] Embodiment 1:

[0050] In the production process of seamless pockets, traditional equipment often needs to rely on multiple independent devices to complete the processes of cloth clamping, hot melt adhesive bag strip positioning, hot pressing and forming, lasing and cutting, etc. This way is not only cumbersome, but also leads to low production efficiency and resource waste. In view of the problems in the background technology, the utility model provides a multi-process laser bag opening device for seamless bag opening, which can realize the high integration of multiple processes on a single device.

[0051] In actual application, the operator first places the cloth to be processed in the cloth positioning clamp plate 16 made of transparent material. This design allows the operator to clearly observe the state of the cloth and make timely adjustments. Then, the cloth is clamped by the clamp cylinder 13 to ensure its stability during the processing. In this process, the design of the clamp can flexibly adapt to different cloth thicknesses, ensuring the convenience and accuracy of the operation.

[0052] Next, the pushing cylinder 3 of the device starts to work, and the negative pressure suction cup 7 is lowered to the hot melt adhesive bag strip positioning seat 8 to accurately adsorb the hot melt adhesive bag strip placed thereon. In this process, since the hot melt adhesive bag strip positioning seat 8 is provided with two grooves, the device can quickly slide to the next groove position after completing a processing cycle without stopping production. This design greatly improves the continuity and smoothness of production, reducing downtime.

[0053] Subsequently, the negative pressure suction disc 7 sends the hot melt glue bag strip to the hot die workbench 9, and the hot die assembly 10 performs hot press forming and bonding here. At this time, the cylinder rod of the hot die cylinder 25 is pressed down, the hot die head 27 is applied to the cloth and the hot melt glue bag strip, and firm bonding is realized. After the hot press forming and bonding is completed, the hot die assembly 10 is quickly reset, and the cloth positioning clamp plate 16 is moved to the lower side of the laser cutting head 18 by the electric trolley 12, and accurate cutting is performed. The rapid connection of the whole set of processes makes the whole production process efficient and smooth.

[0054] Through this integrated operation mode, the multiple processes required in the traditional equipment can be completed on a single device, greatly reducing the frequency of manual intervention and equipment switching. At the same time, due to the double-groove storage design of the hot melt glue bag strip positioning seat 8, the operator can conveniently supplement the hot melt glue bag strip without affecting normal production, avoiding production delay caused by frequent shutdown.

[0055] In addition, the design of the device also effectively reduces the burden of the elastic guide structure. Because the double-groove storage design reduces the elastic distance requirement of the elastic guide structure when supplementing the hot melt glue bag strip, it avoids the possible structural fatigue caused by frequent supplement of the hot melt glue bag strip, and improves the overall stability and service life of the device.

[0056] Embodiment 2:

[0057] In the production process of seamless pockets, efficiency and flexibility are the key to improving competitiveness. In order to solve the problems of multiple process dispersion, poor material adaptability and frequent production shutdown of traditional equipment, the utility model provides an integrated seamless pocket multi-process laser bag opening device, which aims to improve production efficiency and material utilization.

[0058] In this embodiment, the operation process starts from placing the mold plate. The operator first places the cloth to be processed between the hingedly connected first plate body 28 and the second plate body 29, ensuring accurate positioning of the cloth. When the clamp cylinder 13 does not reach the push end position, the structure of the clamp plate allows the front end combination to stably fix the cloth. At this time, the clamp cylinder 13 moves to the push end position, completing the clamping and positioning of the cloth, and preparing for the subsequent process.

[0059] Next, the lifting cylinder 25 is lowered, and the negative pressure suction disc 7 adsorbs the hot melt glue bag strip on the hot melt glue bag strip positioning seat 8. After the negative pressure suction disc 7 adsorbs the hot melt glue bag strip, it is lifted by the lifting cylinder 25, and then the hot melt glue bag strip is accurately pushed to the hot die workbench 9 by the push cylinder 3. After the hot melt glue bag strip is placed, the lifting cylinder 25 is lowered again to ensure good contact between the hot melt glue bag strip and the cloth, and then the adsorption is cancelled.

[0060] The hot die assembly 10 starts to descend at this time, and hot-presses and forms the fabric and the hot melt adhesive bag strip. By controlling the temperature and pressure, the hot die assembly 10 can effectively combine the hot melt adhesive bag strip with the fabric to form a stable connection. After the hot-pressing and forming is completed, the hot die assembly 10 rises to the original position, and the electric trolley 12 drives the combined structure to move to the second working position 17.

[0061] At this position, the laser cutting head 18 is started immediately to accurately cut the fabric that has been hot-pressed and formed. The laser cutting not only ensures high precision of cutting, but also significantly improves the flexibility of production due to its fast response characteristics. When the laser cutting is completed, the cutting head is reset, the clamp cylinder 13 is reset from the pushing end position and released, and the operator can take away the processed fabric.

[0062] The device is also specially designed in a combination mode of the first plate body 28 and the second plate body 29, allowing the operator to process multiple fabrics to be processed on one device at the same time. When one combination is completed, the operator can quickly change to the next combination for processing, which effectively reduces downtime, thereby maintaining production continuity during production peaks and meeting the demand for rapid delivery.

[0063] In addition, the double-groove storage design of the hot melt adhesive bag strip positioning seat 8 allows the next groove position to be easily slid after a processing cycle is completed, further improving work efficiency. During normal processing, the operator can conveniently supplement the hot melt adhesive bag strip in the other groove, ensuring the smoothness of production. At the same time, this design effectively reduces the burden on the elastic guide structure, avoiding fatigue caused by frequent replenishment of hot melt adhesive bag strips, thereby improving the stability and service life of the device.

Therefore, the embodiments should be considered as exemplary only, and are non-limiting, the scope of the present application being defined by the appended claims rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
