[0002] Shoulder straps, as a key detail in fleece clothing, not only serve a decorative purpose but also play an important role in practical applications such as wearing and hanging. Turning the sewn shoulder straps right side out is a crucial step in the manufacturing process. The shoulder straps produced in our workshop are made of napped leather to give them a unique texture and appearance; however, this material significantly increases the difficulty of turning them right side out. For a long time, workers have used thimbles for manual turning, relying on them to assist in the process. However, this manual method is inconvenient and inefficient; furthermore, uneven force applied with the thimble affects the appearance quality of the shoulder straps. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a shoulder loop flipping device, comprising:
[0005] The support body has a mounting part on the upper side;
[0006] A linear actuator is fixedly mounted on the mounting portion; the linear actuator is arranged vertically, and its free end is used for downward movement;
[0007] A fixing block is installed below the mounting part and has an operating distance between it and the mounting part for the free end of the linear actuator to move;

[0009] A control switch is fixed on the fixed block and located on one side of the flip sleeve; the control switch is connected to the linear actuator and is used to drive the linear actuator to move; the shoulder loop is fitted on the flip sleeve and acts on the control switch.
[0010] In one possible implementation, the support is arranged vertically and is used for fixed installation on the upper side of the workbench; the mounting part, the linear driver, the fixing block, the flip sleeve and the control switch are all located outside the workbench.
[0011] In one possible implementation, the mounting part and the fixing block are vertically aligned, the lower end of the mounting part is provided with a horizontally arranged support plate, the support plate is provided with a connecting hole, and the flip sleeve is coaxially aligned with the connecting hole; the linear actuator is inverted and mounted on the support plate, and its free end slides through the connecting hole.
[0012] In one possible implementation, the linear actuator is a cylinder; the control switch includes a solenoid valve and a limit switch connected to the solenoid valve, the solenoid valve being connected to the cylinder, and the limit switch having a lever for opening.
[0013] In one possible implementation, the mounting portion has an inwardly extending mounting groove and a fastener mounted on the mounting portion on the side away from the support body, and the cylinder rod of the cylinder has a fixing plate that mates with the mounting groove, and the fastener is used to fix the fixing plate to the mounting portion.
[0014] In one possible implementation, the support body has support members on both sides, and the support members have vertical and horizontal surfaces that are installed to cooperate with the outer side of the support body and the table surface of the workbench.
[0015] In one possible implementation, the support member is an angle steel, and the support member is provided with two sets of fasteners for fixed connection with the support body and the workbench, respectively.
[0016] In one possible implementation, the shoulder loop flipping device further includes a storage body located directly below the flipping sleeve, the upper end of the storage body having a storage cavity for accommodating the flipped shoulder loop, and the depth of the storage cavity being less than the length of the shoulder loop.
[0017] In one possible implementation, the free end of the linear actuator is provided with a rubber cap, and the rubber cap has an arcuate surface.

The support body is fixedly installed on the upper support surface, and one side is flush with the side support surface. The fixing block and the control switch are fixedly installed on the side support surface. The linear drive and the flipping sleeve are both located outside the worktable.
[0019] The beneficial effects of the shoulder loop flipping device provided by this utility model are as follows: Compared with the prior art, the shoulder loop flipping device of this utility model first aligns the open end of the sewn shoulder loop semi-finished product with the flipping sleeve, so that the shoulder loop is evenly fitted on the outside of the flipping sleeve, ensuring that one end of the shoulder loop is aligned with the entrance of the through hole; at this time, the operator's hand naturally presses the control switch as it moves downward; when the control switch is triggered, the linear actuator receives the electrical signal and drives the free end to move downward in a linear motion. The free end acts downward on the shoulder loop, and combined with the friction between the outside of the flipping sleeve and the inside of the shoulder loop, it forces the shoulder loop to flip along the outer wall of the flipping sleeve towards the through hole. Under the guidance of the through hole, the shoulder loop gradually flips from the reverse side to the front side, and finally passes through the through hole and comes out completely from the bottom; finally, the operator takes out the flipped shoulder loop from the bottom of the flipping sleeve, and the linear actuator automatically resets to the initial position under the action of the control circuit, waiting for the next operation. The entire process eliminates the need for frequent manual adjustments to the ejector pin, replacing manual force with mechanical power and transforming the traditional "manual, tentative sleeve turning" into "precise mechanical pushing." This method, utilizing the high-speed reciprocating motion of the linear actuator and the instantaneous response of the control switch, significantly reduces the sleeve turning time compared to manual operation, improving work efficiency. Simultaneously, the coordinated operation of the sleeve turning sleeve and the free end of the linear actuator ensures uniform force distribution on the sleeve during the turning process, guaranteeing the processing quality of the sleeve.

[0033] Please see Figures 1 to 6The present invention provides a shoulder loop flipping device. A shoulder loop flipping device includes a support body 10, a linear actuator 20, a fixing block 30, a flipping sleeve 40, and a control switch 50. A mounting portion 11 is provided on the upper end of one side of the support body 10. The linear actuator 20 is fixedly mounted on the mounting portion 11. The linear actuator 20 is vertically arranged, and its free end is used for downward movement. The fixing block 30 is installed below the mounting portion 11, and there is an operating distance between the fixing block 30 and the mounting portion 11 for the free end of the linear actuator 20 to move. The flipping sleeve 40 is fixedly mounted on the fixing block 50. The fixed block 30 is positioned above and below the linear actuator 20; the flip sleeve 40 is provided with a through hole 41 for flipping the shoulder loop, the shoulder loop is fitted onto the outside of the flip sleeve 40, and the flipped shoulder loop passes through the through hole 41 and exits from the lower end of the flip sleeve 40; the control switch 50 is fixed on the fixed block 30 and located on one side of the flip sleeve 40; the control switch 50 is connected to the linear actuator 20 and is used to drive the linear actuator 20 to move; the shoulder loop is fitted onto the flip sleeve 40 and acts on the control switch 50.
[0034] Compared with the prior art, the shoulder loop flipping device provided by this utility model uses a support body 10 as its basic structure. The mounting part 11 on one upper side provides a fixed carrier for the linear actuator 20. The free end of the vertically arranged linear actuator 20 can move downwards, providing a power source for the flipping process. A fixing block 30 is installed below the mounting part 11 and forms an operating gap with the mounting part 11, reserving space for the movement of the linear actuator 20 and providing a mounting base for the flipping sleeve 40. The flipping sleeve 40 and the linear actuator... The actuator 20 is positioned vertically, and its internal through hole 41 is the key channel for the shoulder loop flipping. Before flipping, the shoulder loop is fitted onto the outside of the flipping sleeve 40. After flipping, the finished product needs to pass through the through hole 41 and exit from the bottom. The through hole 41 is precisely matched with the specifications of the shoulder loop and can play a guiding and shaping role during the flipping process. The control switch 50 is integrated on the fixing block 30 and electrically connected to the linear actuator 20. Its position is designed so that it will directly act on the control switch 50 when the shoulder loop is fitted, forming an automatic control mechanism of "touch trigger".
[0035] The operating steps are as follows: First, the worker aligns the open end of the sewn shoulder loop semi-finished product with the flipping sleeve 40, so that the shoulder loop is evenly fitted onto the outside of the flipping sleeve 40, ensuring that one end of the shoulder loop is aligned with the entrance of the through hole 41; at this time, the worker's hand naturally presses the control switch 50 as it moves downward; when the control switch 50 is triggered, the linear actuator 20 receives the electrical signal and drives the free end to move downward in a straight line. The free end acts downward on the shoulder loop, and combined with the friction between the outside of the flipping sleeve 40 and the inside of the shoulder loop, it forces the shoulder loop to flip along the outer wall of the flipping sleeve 40 toward the through hole 41. Under the guidance of the through hole 41, the shoulder loop gradually flips from the reverse side to the front side, and finally passes through the through hole 41 and comes out completely from the bottom; finally, the worker takes out the flipped shoulder loop from the bottom of the flipping sleeve 40, and the linear actuator 20 automatically resets to the initial position under the action of the control circuit, waiting for the next operation. The entire process eliminates the need for frequent manual adjustments to the ejector pin, replacing manual force with mechanical power and transforming the traditional "manual, tentative flipping" into "precise mechanical pushing." This method, utilizing the high-speed reciprocating motion of the linear actuator 20 in conjunction with the instantaneous response of the control switch 50, significantly shortens the flipping time of the shoulder loop compared to manual operation, thus improving work efficiency. Simultaneously, the coordinated operation of the flipping sleeve 40 and the free end of the linear actuator 20 ensures uniform force distribution on the shoulder loop during the flipping process, guaranteeing the processing quality of the shoulder loop.
[0036] Please see Figure 1 and Figure 2 , Figure 5 and Figure 6 In one specific embodiment of the shoulder loop flipping device provided by this utility model, the support body 10 is arranged vertically and is used for fixed installation on the upper side of the workbench 70; the mounting part 11, linear driver 20, fixing block 30, flipping sleeve 40, and control switch 50 are all located outside the workbench 70. By vertically fixing the support body 10 to the upper side of the workbench 70, the core components such as the mounting part 11 and linear driver 20 are all located outside the workbench 70. This layout utilizes the edge space of the workbench 70 to achieve stable installation of the device without occupying other areas of the workbench 70. The operator is located outside the workbench 70 and corresponding to the device, thus facilitating and quickly performing the shoulder loop flipping work.
[0037] Please see Figures 1 to 3 , Figure 5 and Figure 6In a specific embodiment of the shoulder loop flipping device provided by this utility model, the mounting part 11 and the fixing block 30 are vertically aligned. The lower end of the mounting part 11 is provided with a horizontally arranged support plate 12, which has a connecting hole. The flipping sleeve 40 is coaxially aligned with the connecting hole. The linear actuator 20 is inverted and mounted on the support plate 12, with its free end sliding through the connecting hole. The horizontal support plate 12 at the lower end of the mounting part 11 provides a stable mounting base for the linear actuator 20. Its connecting hole is coaxially aligned with the flipping sleeve 40, ensuring that the free end of the linear actuator 20 can slide precisely along the connecting hole after being inverted. This structure ensures that the driving force acts vertically on the shoulder loop through the coaxial design, avoiding flipping difficulties or fabric damage caused by skewness. The support plate 12 enhances the overall structural stability and prevents components from loosening. The inverted installation makes the layout compact, improves the utilization of operating space, and significantly improves the flipping accuracy.
[0038] Please see Figure 1 and Figure 2 , Figure 5 and Figure 6 In one specific embodiment of the shoulder loop flipping device provided by this utility model, the linear actuator 20 is a cylinder; the control switch 50 includes a solenoid valve 51 and a limit switch 52 connected to the solenoid valve 51. The solenoid valve 51 is connected to the cylinder, and the limit switch 52 is provided with a pressure rod 53 for opening. Using a cylinder as the linear actuator 20, combined with the control switch 50 composed of the solenoid valve 51 and the limit switch 52, the cylinder provides a stable linear driving force through air pressure. The pressure rod 53 of the limit switch 52 is triggered when the shoulder loop is fitted, thereby controlling the opening and closing of the air circuit of the solenoid valve 51, achieving precise start-stop and displacement of the free end of the cylinder. This method utilizes the fast response and uniform thrust characteristics of the pneumatic system to ensure stable force on the stiff shoulder loop during flipping, avoiding force deviations caused by manual operation; the triggering mechanism of the pressure rod 53 ensures that the device only starts when the shoulder loop is correctly installed, preventing malfunction; the pneumatic components have a simple structure and are easy to maintain.
[0039] Please see Figure 1 and Figure 3As a specific embodiment of the shoulder loop flipping device provided by this utility model, the mounting part 11 has an inwardly extending mounting groove 13 and a fastener 14 mounted on the side away from the support body 10. The cylinder rod has a fixing plate 15 that mates with the mounting groove 13. The fastener 14 is used to fix the fixing plate 15 to the mounting part 11. The mounting part 11 has an inwardly extending mounting groove 13. The fixing plate 15 on the cylinder rod is installed into the mounting groove 13, and then fixed to the mounting part 11 by the fastener 14. The mounting groove 13 enables precise positioning of the cylinder and avoids installation misalignment from affecting the flipping alignment; the fastener 14 provides a stable connection and prevents the cylinder from loosening during operation; this structure facilitates cylinder disassembly and assembly, and is convenient for maintenance or replacement, while improving the overall installation accuracy and stability, and ensuring the continuous and accurate application of driving force during the flipping process.
[0040] Please see Figure 1 and Figure 2 , Figure 5 and Figure 6 As a specific embodiment of the shoulder loop flipping device provided by this utility model, support members 16 are provided on both sides of the support body 10, and the support members 16 have a vertical surface and a horizontal surface that are installed in conjunction with the outer side of the support body 10 and the table surface of the worktable 70. The support members 16 on both sides of the support body 10 form a double-fitting installation structure by fitting the vertical surface with the outer side of the support body 10 and the horizontal surface with the worktable 70. The vertical surface enhances the connection strength between the support body 10 and the support member 16, and the horizontal surface increases the contact area with the worktable 70. The combination of the two can disperse the impact force and gravity when the equipment is working. This design significantly improves the installation stability of the support body 10, reduces the deviation caused by the shaking of the equipment during the flipping process, and enhances the overall load-bearing capacity.
[0041] Please see Figure 1 and Figure 2 , Figure 5 and Figure 6 In one specific embodiment of the shoulder loop flipping device provided by this utility model, the support member 16 is made of angle steel, with its two vertical surfaces respectively attached to the outer side of the support body 10 and the surface of the worktable 70. Two sets of fasteners 14 fix the angle steel to the support body 10 and the worktable 70 respectively. The angle steel has high rigidity, and with the double fixing, it can greatly improve the installation stability of the support body 10, prevent the equipment from shaking during operation, and is easy to disassemble and assemble. Preferably, holes are opened on the angle steel, the worktable 70, and the support body 10, and the fasteners 14 are bolts.
[0042] Please see Figure 1 , Figure 4 and Figure 5As a specific embodiment of the shoulder loop flipping device provided by this utility model, the shoulder loop flipping device also includes a storage body 60 located directly below the flipping sleeve 40. The upper end of the storage body 60 is provided with a storage cavity 61 for accommodating the flipped shoulder loop, and the depth of the storage cavity 61 is less than the length of the shoulder loop. The storage body 60 is located directly below the flipping sleeve 40, and the storage cavity 61 at its upper end is specifically used to receive the flipped shoulder loop, and the depth of the storage cavity 61 is designed to be less than the length of the shoulder loop. This structure, through the storage body 60 arranged in opposite directions, ensures that the shoulder loop can accurately fall into the storage cavity 61 after passing through the lower end of the flipping sleeve 40, avoiding stains or fabric wear caused by falling to the ground; and the depth of the storage cavity 61 is less than the length of the shoulder loop, so that the top of the shoulder loop naturally protrudes out of the cavity, and the staff can easily take the shoulder loop out of the storage cavity 61. An L-shaped plate 62 is pre-installed on the workbench 70. The upper end of the vertical plate of the L-shaped plate 62 is fixedly installed on the lower end surface of the workbench 70, so that the horizontal plate of the L-shaped plate 62 extends outward to correspond vertically with the flip sleeve 40; then the storage body 60 is fixedly installed on the horizontal plate.
[0043] Please see Figure 1 and Figure 3 As a specific embodiment of the shoulder loop flipping device provided by this utility model, a rubber cap 21 with an arc-shaped surface 22 is provided at the free end of the linear actuator 20. The rubber material is elastic, and the arc-shaped surface 22 can increase the contact area with the shoulder loop. When the linear actuator 20 drives the free end to press down, the rubber cap 21 makes flexible contact with the inner side of the shoulder loop through the arc-shaped surface 22, avoiding hard contact that could cause scratches or indentations to the napped leather fabric.
[0044] Please see Figure 5 and Figure 6 As a specific embodiment of the shoulder loop flipping device provided by this utility model, the shoulder loop flipping device also includes a worktable 70, which has an upper support surface 71 and a side support surface 72. The support body 10 is fixedly installed on the upper support surface 71, and one side is flush with the side support surface 72. The fixing block 30 and the control switch 50 are fixedly installed on the side support surface 72. The linear driver 20 and the flipping sleeve 40 are both located outside the worktable 70. The worktable 70 serves as the load-bearing structure of the entire device, forming a three-dimensional installation structure through the upper support surface 71 and the side support surface 72: the support body 10 is fixed to the upper support surface 71 and one side is flush with the side support surface 72, ensuring a tight fit between the device and the worktable 70; the fixing block 30 and the control switch 50 are installed on the side support surface 72, making it easy for operators to quickly access them during operation; the linear driver 20 and the flipping sleeve 40 are located outside the worktable 70, avoiding occupying space on the worktable 70.
[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
