[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] In one specific implementation, such as Figures 1-2 As shown, the headrest cover folding fixture provided by this utility model includes a support structure, a top rod assembly, and a pneumatic assembly; wherein, the support structure is placed on the ground or a workbench, the top rod assembly is installed on the support structure, the top rod assembly has an air passage, and an air outlet is provided at the top of the air passage; the pneumatic assembly is connected to the air passage and injects gas into the air passage.

[0029] During use, place the cover on the top rod assembly, pull the cover with both hands, and activate the pneumatic component to blow air into the cover cavity while flipping it over. By incorporating a top rod assembly with air channels and outlets, and a connected pneumatic component, air can be blown out from the outlets during the folding process of the headrest cover, effectively reducing creases formed when flipping the cover. The blowing air also provides support and cushioning to the cover, resulting in more even force distribution during folding and preventing creases caused by excessive localized force. This improves the appearance quality of the headrest cover and enhances the overall product quality.

[0030] The aforementioned support structure can be a base plate 1, on which the top rod assembly is mounted. Concretizing the support structure as a base plate 1 makes the entire headrest cover folding fixture more stable and facilitates the installation and placement of the top rod assembly. As a supporting foundation, the base plate 1 can bear the weight of the top rod assembly and other components such as the headrest cover, ensuring the stability of the fixture during use and preventing wobbling or tilting during folding due to an unstable support structure, which could affect the folding effect and the quality of the cover.

[0031] Theoretically speaking, the support structure is not limited to the form of a base plate 1. It can be a frame structure, which can be composed of multiple metal or plastic rods to form a stable support space. The top rod assembly is installed at a specific position in the frame.

[0032] To achieve height adjustment of the push rod assembly, the push rod can adopt a telescopic structure. Specifically, the push rod assembly includes a first pipe 2 and a second pipe 4. The first pipe 2 has a first through hole, and an air nozzle 3 is provided on the pipe wall of the first pipe 2. The air nozzle 3 is connected to the first through hole and to the pneumatic assembly. The second pipe 4 has a second through hole, and the first pipe 2 and the second pipe 4 are movably connected in the vertical direction. The first through hole and the second through hole are connected to form the air passage, and the top of the second through hole forms the air outlet.

[0033] In practical use, the relative positions of the first pipe 2 and the second pipe 4 can be flexibly adjusted according to the size and shape of different headrest covers and the height of the staff, so that the air outlet can be accurately aligned with the folded part of the headrest cover, thereby better exerting the function of blowing air to reduce creases and improving the versatility and adaptability of the tooling. The height of the push rod assembly can be adjusted, for example, in the range of 0.8m to 1.2m, to accommodate employees of different heights.

[0034] Furthermore, at least a portion of the second pipe 4 is provided with external threads. The second pipe 4 is inserted into the first through hole and fixedly connected to the first pipe 2 by a nut 5 that engages with the external threads. This connection method makes the connection between the first pipe 2 and the second pipe 4 more robust and reliable, capable of withstanding certain tensile and compressive forces, ensuring that the push rod assembly will not loosen or fall off when the pneumatic assembly injects gas into the air passage. Simultaneously, the threaded connection facilitates fine-tuning of the relative positions of the first pipe 2 and the second pipe 4. By tightening or loosening the nut 5, the tightness of the connection and the relative position between the two pipes can be precisely adjusted, thereby better meeting the requirements of different headrest cover folding times for the air passage and air outlet positions, further improving the stability and adjustability of the tooling. Moreover, the threaded connection allows the second pipe 4 to be quickly switched to adapt to the folding of different sized covers.

[0035] In some embodiments, the push rod assembly further includes a push ball, which is a hollow structure connected to the air passage, the air outlet is opened at the push ball, and the push ball is threadedly connected to the second pipe.

[0036] The aforementioned pneumatic components include an air source and an air pipe 8. The air source refers to a compressed air source, which enters through the air inlet pipe 8. The compressed air source is controlled to open and close by a foot switch. One end of the air pipe 8 is connected to the air source, and the other end is connected to the air nozzle 3. During the folding process of the headrest cover, the operator can operate the headrest cover with both hands while controlling the foot switch with their foot to achieve timely gas injection, improving operational convenience and work efficiency. The air pipe 8, as a gas transmission channel, can stably deliver the gas generated by the air source to the air passage of the push rod assembly, ensuring that the gas can be smoothly blown out from the air outlet, thereby effectively reducing creases and ensuring the normal operation and functional realization of the entire headrest cover folding fixture.

[0037] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solution of this utility model should be included within the scope of protection of this utility model.
