The auxiliary conveying mechanism 3 is movably arranged inside the sliding groove 14 and is adjusted according to the specific conditions of the installation. The auxiliary conveying mechanism 3 can clean the inner lining plate body 5 while conveying it, so as to reduce the debris on the inner lining plate body 5 falling into the inside of the luggage box during the processing;

[0042] A cleaning mechanism 4 is provided on the side wall of the positioning vertical rod 13 away from the sliding groove 14, and is used to clean foreign debris during the conveying process;

[0043] The inner lining plate body 5 has a metal support frame inside, and the inner lining plate body 5 can play a certain supporting role, thereby supporting and limiting the clothes and the like inside the suitcase, reducing internal chaos.

[0044] During the processing, in order to ensure the stability of the suitcase itself, the support mechanism 2 includes a slide plate 21 and a positioning plate 22. The slide plate 21 is movably clamped inside the transmission slot 11. A slot is provided on the top of the slide plate 21, and the positioning plate 22 is installed inside the slot. The cross-section of the positioning plate 22 is right-angled. The positioning plate 22 is used to rest against the outer wall of the suitcase during the limiting process. The positioning plate 22 can push one end of the suitcase against the welding plate 12, and can limit the suitcase to prevent movement during the processing.

[0045] In order to reduce the deformation of the luggage itself caused by the use of cushioning materials during the processing, a plurality of slots are installed on the top of the positioning plate 22, and a clamping plate 23 is movably clamped inside the slot. The top of the clamping plate 23 is "U"-shaped and elastic. The clamping plate 23 is used to clamp on the side of the luggage to play a supporting role. The clamping plate 23 can be clamped on the side wall of one end of the luggage to support and limit it, thereby reducing the deviation during the subsequent installation and sewing of the inner lining plate body 5.

[0046] A plurality of hollow grooves are provided on the surface of the clamping plate 23, and a buffer pressure plate 24 is clamped inside the hollow groove. The buffer pressure plate 24 is elastic, and one end of the buffer pressure plate 24 is against the inner wall of the suitcase. The buffer pressure plate 24 can be against the inner wall of the suitcase under the action of its own elasticity, and can adapt and adjust itself according to different subsequent suitcases.

[0047] During the installation of the lining plate body 5, due to the different sizes of luggage cases, the installation position and angle thereof are different. The auxiliary conveying mechanism 3 includes a transmission frame 31, a movable plug rod 32 and a support shaft 33. The transmission frame 31 is movably mounted inside the sliding groove 14. A pair of rectangular plates 35 are mounted on the inner wall of the transmission frame 31. A plug hole is provided at the bottom of the rectangular plate 35. The movable plug rod 32 is movably mounted inside the plug hole. The support shaft 33 is mounted at the bottom of the movable plug rod 32 at both ends. One end of the lining plate body 5 can be against the support shaft 33, which can provide auxiliary support during the sewing process, thereby reducing the tilting and offset of the position of the lining plate body 5 during the sewing process.

[0048] A plurality of straight grooves are provided on the side wall of the support shaft 33, and compression plates 34 are each mounted inside the straight grooves. A buffer groove is provided on the top of the compression plate 34, and a buffer ball is installed inside the buffer groove. The buffer ball can be arranged in contact with the inner lining plate body 5. During the supporting process, the friction force can be enhanced to prevent the inner lining plate body 5 from sliding during the sewing process.

[0049] In order to ensure the cleanliness of the lining plate body 5, it needs to be cleaned before sewing. A telescopic rod 351 is installed on the rectangular plate 35, and a rotating disk 36 is installed at one end of the telescopic rod 351. An annular groove is provided on the side wall of the rotating disk 36, and a plurality of arc grooves 361 are provided on the rotating disk 36. A rubber plate is inserted inside the arc groove 361, and the rubber plate is located inside the annular groove. The rubber plate can be rubbed and squeezed with the reset plate 37, so that the reset plate can be shaken in a small compound manner, which can make the lining plate body 5 swing during the transmission process, and can cooperate with the cleaning mechanism 4 to quickly shake off the debris and thread ends adhered to its surface;

[0050] A plurality of reset plates 37 are provided on the outer wall of the rotating disk 36. When the reset plates 37 are deformed, their bottoms are in contact with the rubber plates. A plurality of positioning shafts 371 are installed on the surfaces of the reset plates 37. The positioning shafts 371 are made of rubber. The positioning shafts 371 can rest against the edges on both sides of the inner lining plate body 5 during transmission, thereby playing the role of transmission limiter to prevent position deviation during transmission and affect subsequent processing.

[0051] In order to clean the inner lining plate body 5, the cleaning mechanism 4 includes a docking plate 41, an adjusting shaft 42 and a storage box 46. The docking plate 41 is installed on the positioning vertical rod 13. The docking plate 41 is provided with a slide groove. The adjusting shaft 42 is movably arranged inside the slide groove. The spacing can be adjusted according to the size and thickness of the inner lining plate body 5 to ensure the cleaning effect and reduce the accumulation of dust and debris. The docking plate 41 and the adjusting shaft 42 are vertically arranged. The bottom adjusting shaft 42 is clamped with a connecting shaft 44. A plurality of support arms are installed at the bottom of the connecting shaft 44. The storage box 46 is clamped on one side of the support arm. The storage box 46 is located directly below the adjusting shaft 42. The storage box 46 can recycle the debris and garbage generated by cleaning.

[0052] In order to make the debris accumulate inside the storage box 46 after collection, a swing plate 43 and a reset lever 45 are respectively provided on the adjusting shaft 42. The swing plate 43 is semicircular and is clamped on the top adjusting shaft 42. A pair of elastic sheets 431 are provided between the swing plates 43. The reset lever 45 is arranged on the bottom adjusting shaft 42. The reset lever 45 and the support arm are staggered. During the movement of the reset lever 45, there is contact and friction with the support arm. The reset lever 45 can drive the support arm to swing slightly, thereby causing the storage box 46 to move, which is convenient for compacting and stacking the internal debris. A pneumatic shaft 451 is installed at one end of the inner wall of the reset lever 45. A pair of fixed balls are fixedly connected to the surface of the pneumatic shaft 451, and a rubber shaft can be installed between the fixed balls. The rubber shaft can continuously slap the bottom of the inner lining plate body 5 during transportation, which can play a role in auxiliary cleaning and reduce the situation where thread ends and cloth debris are stuck in the gap of the inner lining plate body 5.

[0053] In order to prevent the collected debris from flying, a plurality of blocking shafts 47 are provided inside the storage box 46, and a plurality of compression rings 471 are fixedly connected to the blocking shaft 47. The compression rings 471 are staggered. The blocking shaft 47 can swing with the storage box 46, and can cause friction and compression between the compression rings 471. At the same time, the dust and debris that fall on the blocking shaft 47 can be rubbed, so that they accumulate into a ball and then fall into the storage box 46.

[0054] A storage bag 51 is installed on the top of the lining board body 5, and a plurality of buffer plates 52 are installed on the bottom of the lining board body 5. The buffer plates 52 are in a honeycomb grid shape, and a plurality of rubber sheets are provided at the bottom of the buffer plates 52. The buffer plates 52 can play a buffering role during transportation, and the rubber sheets can be pressed against one side of the stacked clothes to play an auxiliary limiting role.

[0055] Working principle: First, when the inner lining plate body 5 needs to be installed and sewn, it can be transported and cleaned with the help of the auxiliary conveying mechanism 3 and the cleaning mechanism 4 to reduce the debris and thread ends remaining on its surface, and the supporting mechanism 2 can support and limit the luggage box to ensure the stability in the subsequent processing process, and will not deviate during the sewing process. As the inner lining plate body 5 is transmitted inside the equipment, the swing plate 43 and the reset clamping rod 45 can rub against the two sides of the inner lining plate body 5, and the surface of the inner lining plate body 5 can be knocked and rubbed alternately, and the surface of the inner lining plate body 5 can be quickly cleaned to reduce the impact on subsequent processing, and as the bottom of the inner lining plate body 5 can be squeezed between the top of the reset clamping rod 45, the rubber shaft can continuously knock and clean the inner lining plate body 5 to reduce the cleaning of debris remaining in its gap or clamping space;

[0056] Then, during the activity of the reset card rod 45, it can cause friction between the support arm and the storage box 46, thereby pushing the storage box 46 to move slightly, and the debris and impurities stuck between the blocking shafts 47 can be shaken off into the storage box 46, reducing the residual debris. As the storage box 46 moves, the blocking shaft 47 can move under the action of inertia, and the interlaced compression rings 471 can be rubbed and squeezed to collect and rub the debris and impurities laid on the top of the blocking shaft 47, and condense into a ball and fall into the storage box 46. While playing a collection role, it can also play a certain dust reduction role, reducing the situation where the debris is flying in the air again. In the transmission process, the position of the telescopic rod 351 can be adjusted, so that the reset plate 37 can be pressed against the surface of the inner lining plate body 5, and can be against the top of the inner lining plate body 5. It can play an auxiliary support role in cooperation with the support shaft 33 to prevent it from deviating during the subsequent sewing process.

[0057] Finally, before sewing, the clamping plate 23 is inserted into the side wall of the suitcase to play a supporting role, which can reduce the tilting deformation of the soft-shell suitcase during the sewing process, reduce sewing deviation, etc., and ensure the processing quality of the equipment.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
