Technical Field

[0001] This utility model relates to the field of leather bag interior lining technology, specifically an automatic leather bag interior lining bonding machine. Background Technology

[0002] The inner lining of a handbag is the inner layer material that fits the bag's outer fabric. Common materials include cotton, nylon, and polyester. It is wear-resistant, scratch-resistant, and easy to clean. Its color and texture often match the style of the bag and is an important part of the handbag's functionality and aesthetics.

[0003] The automatic lining bonding machine for leather bags is a piece of equipment used in leather bag production to automatically bond the lining to the bag body. It can quickly complete the compaction and bonding of the outer shell and the inner lining of the leather bag, adapt to leather bags of various sizes, solve the problems of low efficiency and inconsistent positioning of manual bonding, improve bonding accuracy and finished product quality, and help the large-scale production of leather bags.

[0004] Existing automatic bonding machines for leather bag linings still have the following problems: it is inconvenient to quickly install the welding head. Usually, the welding head needs to be installed and fixed with bolts. However, the frequent use of bolt fixing can easily damage or wear down the threads at the threaded hole, making it difficult to install effectively later. In order to address the above problems, an automatic bonding machine for leather bag linings is proposed. Utility Model Content

The middle of the left side of the vertical plate 6 is provided with a third sliding groove 23, and the inner wall of the third sliding groove 23 is connected to the handle 24. Handle 24 is slidably connected and allows it to slide stably via third groove 23. A second chamber 20 is provided in the middle of the left side of the bottom of the tabletop 9. A top block 22 is slidably connected to the inner wall of the second chamber 20. A third spring 28 is fixedly connected between the top of the top block 22 and the second chamber 20. The spring force of the third spring 28 presses the top block 22 tightly, making it firmly inserted into the left upright plate 6. A second groove 21 is provided on both the left and right sides of the inner wall of the second chamber 20. The inner wall of the second groove 21 is slidably connected to the top block 22. The movement range of the top block 22 is determined by the second groove 21. The bottom of the outer ring of the top block 22 passes through and is slidably connected to the middle of the top of the left upright plate 6. The top of the ejector 26 contacts the top block 22. The ejector 26 pushes the top block 22 out, making it detach from the upright plate 6.

[0031] Working principle: When convenient installation of the ultrasonic welding head 12 is required, the snap-fit ​​strip 16 is inserted into the bottom of the connecting block 14. Due to the special structure of the snap-fit ​​strip 16 and the snap-fit ​​connector 15, the snap-fit ​​strip 16 pushes open the snap-fit ​​connector 15 and inserts it all the way in. The snap-fit ​​connector 15 is inserted into the hole on the surface of the snap-fit ​​strip 16. When disassembly is required, the snap-fit ​​connector 15 is pulled by the handle 11 to press the first spring 18 and move along the inner wall of the first chamber 17 and disengage from the snap-fit ​​strip 16, thus easily removing the ultrasonic welding head 12. Then, the outer shell 7 and the inner lining fabric 8 of the bag are precisely placed according to the alignment line 4. After opening the cylinder 10 and the ultrasonic welding head 12, the outer shell 7 and the inner lining fabric 8 of the leather bag can be bonded together. After long-term use, the top of the tabletop 9 will turn black. If it is not removed for maintenance or cleaning, it is easy to cause charring. By pushing the top block 22 upward with the handle 24, the top block 22 presses the third spring 28 and moves along the inner wall of the second chamber 20. The movement range of the top block 22 is limited by the second slide groove 21, so that the top block 22 just detaches from the upright plate 6. Then the tabletop 9 is pulled out along the mounting groove 29, so that the tabletop 9 can be easily removed for maintenance or cleaning.
