Description

Technical Field

[0001] This application belongs to the technical field of hat production equipment, specifically relating to a hat printing and fixing fixture. Background Technology

[0002] Hats, especially certain military caps (such as berets and peaked caps), require the brim to be sewn or glued to a fixed location after the hat is finished. Military uniforms have high quality requirements, so lines need to be drawn on the outer perimeter of the hat before sewing the brim to facilitate the sewing of the brim.

[0003] However, the hat has a flexible structure and is easily deformed during printing, which greatly affects the printing process. Employees need to fix the hat in place before printing. The inner circumference of the hat is curved, making it difficult for employees to fix, resulting in a long overall printing time and reduced printing efficiency. Special fixing blocks can be used to fix the hat from the inside, but these blocks can only be used for one type or size of hat. Producing multiple types or sizes of hats requires multiple special fixing blocks, increasing the cost of use. If a new type of hat is required, the special fixing blocks need to be customized, resulting in high operating costs. Utility Model Content

[0004] This application provides a hat printing and fixing fixture, which aims to solve the technical problems of difficulty in fixing hats before printing and high cost of using special fixing blocks in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a hat printing fixing fixture, comprising:

[0006] Base;

[0007] The lower mold is fixed on the base;

[0008] A lifting assembly includes a lifting device disposed on the base, the lifting device having a telescopic end at its top for vertical lifting; and

[0009] An upper mold is located at the telescopic end, above the lower mold, and aligned vertically with the lower mold. The outer periphery of the upper mold and the outer periphery of the lower mold cooperate to form an elliptical cylindrical structure. The generatrix of the elliptical cylindrical structure is parallel to the horizontal direction. One end of the elliptical cylindrical structure away from the telescopic end extends into the inner cavity of the hat and fits against the inner circumferential surface of the hat.

[0010] In one possible implementation, the lifting device is a vertically mounted telescopic motor, which is located on a base. The telescopic rod of the telescopic motor extends and retracts in the vertical direction, and a lifting plate is connected to the end of the telescopic rod away from the telescopic motor. The lifting plate forms the telescopic end.

[0011] In one possible implementation, the upper mold includes an integrally formed upper connecting mold and an upper forming mold, the upper connecting mold being connected to the telescopic end, and the upper forming mold having a semi-elliptical structure with a top surface being a semi-elliptical arc surface.

[0012] In one possible implementation, the lower mold includes an integrally formed lower connecting mold and a lower forming mold. The lower connecting mold is disposed on the base, and the lower forming mold has a semi-elliptical structure with a semi-elliptical arc surface at its bottom. The upper forming mold and the lower forming mold are fitted together to form an elliptical cylindrical structure.

[0013] In one possible implementation, a first snap-fit ​​protrusion is formed at the bottom of the end face of the upper forming mold away from the upper connecting mold, and a first snap-fit ​​groove is formed at the top of the end face of the lower forming mold away from the lower connecting mold corresponding to the first snap-fit ​​protrusion. The first snap-fit ​​protrusion and the first snap-fit ​​groove engage vertically to limit the displacement of the upper forming mold in the minor axis direction of the elliptical cross-section.

[0014] In one possible implementation, the bottom surface of the upper connecting mold is provided with a second snap-fit ​​protrusion along its own long axis, and the top surface of the lower connecting mold is provided with a second snap-fit ​​groove corresponding to the second snap-fit ​​protrusion. The second snap-fit ​​protrusion and the second snap-fit ​​groove are inserted and engaged to limit the displacement of the upper connecting mold in its own busbar extension direction.

[0015] In one possible implementation, the base is provided with a connecting block, which is aligned vertically with the lifting plate. The connecting block has an internal receiving channel with openings at the top and bottom. The lifting device is located in the receiving channel, and the lower mold is connected to the side of the connecting block.

[0016] In one possible implementation, the lifting assembly further includes a height limiting plate and a support frame. The support frame is mounted on the base, and the height limiting plate is located on top of the support frame. The surface of the height limiting plate is perpendicular to the vertical direction, and the height limiting plate is positioned above the lifting plate to limit the vertical displacement of the lifting plate.

[0017] In one possible implementation, the support frame includes two vertical plates and a support plate. The surface of the support plate is perpendicular to the surfaces of the two vertical plates. The two vertical plates are symmetrically arranged on both sides of the support plate and enclose the support plate to form a concave structure. The height limiting plate is located at the top of the support plate, and the height limiting plate and the two vertical plates are located on opposite sides of the support plate.

[0018] In one possible implementation, the upper connecting mold has a fixing hole, the hat printing fixing fixture also includes a fastener, the fastener includes a bolt with a nut, the telescopic end has a threaded hole, the bolt passes through the fixing hole and is threaded into the threaded hole, and the nut cooperates with the telescopic end to clamp and fix the upper connecting mold.

[0019] The hat printing fixture provided in this application, compared with existing technologies, features an upper mold that can move up and down via the telescopic end of a lifting component. The upper and lower molds are aligned vertically, and their outer circumferences form an elliptical cylindrical structure that fits snugly against the inner surface of the hat. When this elliptical cylindrical structure extends into the hat's cavity, it stably secures the hat, solving the problem of difficulty in securing the hat due to its curved inner surface. This automatic hat fixing significantly reduces the difficulty of operation for employees and improves work efficiency. The precise alignment of the upper and lower molds and the elliptical cylindrical structure they form ensure that the hat maintains a stable shape during the printing process. During printing, the hat is firmly fixed to the fixture and will not deform due to external forces or its own flexible structure, ensuring the accuracy and quality of the printing.

[0041] Please refer to the following: Figures 1 to 5 The hat printing fixture provided in this application is described below. The hat printing fixture includes a base 1, a lower mold 2, a lifting assembly 3, and an upper mold 4. The lower mold 2 is fixed on the base 1; the lifting assembly 3 includes a lifter 32, which is located on the base 1, and the top of the lifter 32 forms a telescopic end for vertical lifting; the upper mold 4 is located at the telescopic end, above the lower mold 2, and the upper mold 4 and the lower mold 2 are aligned vertically. The outer periphery of the upper mold 4 and the outer periphery of the lower mold 2 cooperate to form an elliptical cylindrical structure. The generatrix of the elliptical cylindrical structure is parallel to the horizontal direction. The end of the elliptical cylindrical structure away from the telescopic end extends into the inner cavity of the hat and fits against the inner circumferential surface of the hat.

[0042] It should be noted that the generatrix of an elliptical cylinder structure refers to the perpendicular connecting line between the two end faces of the elliptical cylinder structure.

[0043] It should be noted that after the upper mold 4 and the lower mold 2 of this application are attached together, they can be inserted into the inside of the hat. At this time, the upper mold 4 is lifted by the lifting device 32, and the upper mold 4 and the lower mold 2 support the hat in the vertical direction to achieve the shaping and fixing of the hat, which makes it convenient for employees to draw lines.

[0044] The hat printing and fixing fixture provided in this embodiment, compared with the prior art, allows the upper mold 4 to move up and down via the telescopic end of the lifting component 3. The upper mold 4 and lower mold 2 are aligned vertically, and their outer circumferences form an elliptical cylindrical structure that fits well against the inner circumference of the hat. When this elliptical cylindrical structure extends into the hat's cavity, it stably fixes the hat, solving the problem of difficulty in fixing the hat due to its curved inner circumference. It automatically fixes the hat, greatly reducing the difficulty of operation for employees and improving work efficiency. The precise alignment of the upper mold 4 and lower mold 2, and the elliptical cylindrical structure they form, ensure that the hat maintains a stable shape during the printing process. During the printing operation, the hat is firmly fixed to the fixture and will not deform due to external forces or its own flexible structure, ensuring the accuracy and quality of the printing.

[0045] In some embodiments, see Figure 1 The lifting device 32 is a vertically mounted telescopic motor located on the base 1. The telescopic rod of the motor extends and retracts vertically, with a lifting plate 33 connected to the end of the rod furthest from the motor, forming the telescopic end. The telescopic motor can precisely control the lifting height of the upper mold 4 according to preset parameters, ensuring that the elliptical cylindrical structure formed by the upper mold 4 and the lower mold 2 can accurately extend into the inner cavity of the hat and fit snugly against the inner circumference of the hat. This improves the accuracy of the tooling in fixing the hat and further prevents deformation of the hat during printing due to inaccurate fixing. It reduces labor costs and also minimizes the impact of human factors on printing quality, making the hat printing process more stable and reliable.

[0046] It should be noted that the bottom of the telescopic motor body is connected to the base 1, and the telescopic rod of the telescopic motor passes through the top of the telescopic motor body and extends and retracts vertically.

[0047] Optionally, the telescopic motor can be a DC telescopic motor, a stepper telescopic motor, or a cylinder. The cylinder body is connected to the base 1, and the piston rod of the cylinder extends from the top of the cylinder body and is connected to the lifting plate 33, as long as it can stably drive the upper mold 4 to rise and fall.

[0048] As one embodiment of the connection between the lifting plate 33 and the telescopic end of the lifting device 32, an L-shaped connecting plate is connected to the plate surface of the lifting plate 33 facing the telescopic end. The connecting plate includes an integrally cast vertical plate and a horizontal plate. The vertical plate of the connecting plate is connected to the lifting plate 33, and the horizontal plate of the connecting plate is connected to the top of the telescopic end of the lifting device 32.

[0049] In some embodiments, see Figure 1The upper mold 4 includes an integrally formed upper connecting mold 41 and an upper forming mold 42. The upper connecting mold 41 is connected to the telescopic end, and the upper forming mold 42 has a semi-elliptical structure with a semi-elliptical arc surface on its top surface. The integral molding design ensures the integrity and stability of the structure, making the upper mold 4 more secure during lifting and lowering, and less prone to loosening or deformation. The connection between the upper connecting mold 41 and the telescopic end can accurately transmit the power of the lifting component 3 to the upper mold 4, ensuring that the upper mold 4 can move up and down as required. The semi-elliptical structure of the upper forming mold 42 can better adapt to the arc shape of the inner circumference of the hat. It provides good support and fixation for the hat, preventing the hat from deforming due to its own flexible structure during the printing process and improving the accuracy of the printing.

[0050] In some embodiments, see Figure 1 The lower mold 2 includes an integrally formed lower connecting mold 21 and a lower forming mold 22. The lower connecting mold 21 is located on the base 1, and the lower forming mold 22 has a semi-elliptical structure with a semi-elliptical arc surface at its bottom. The upper forming mold 42 and the lower forming mold 22 are fitted together to form an elliptical cylindrical structure. The connection between the lower connecting mold 21 and the base 1 allows the lower mold 2 to be stably fixed on the base 1, providing a reliable foundation for the entire fixture and preventing it from shaking during operation. The lower forming mold 22 corresponds to the upper forming mold 42, and when the upper and lower molds 2 are fitted together, they form an elliptical cylindrical structure. This elliptical cylindrical structure can fit tightly against the inner circumference of the hat, further enhancing the fixing effect on the hat, reducing deformation of the hat during the printing process, and improving the printing quality. This precise fit allows for a tighter fit against the inner circumference of the hat; it can be applied to hats of different specifications but similar shapes, improving the versatility of the fixture, enabling it to play a role in various hat printing operations, reducing production costs, and improving production efficiency.

[0051] In some embodiments, see Figure 1 and Figure 3 A first engaging protrusion 421 is formed at the bottom of the end face of the upper forming mold 42 away from the upper connecting mold 41. A first engaging groove 221 is formed at the top of the end face of the lower forming mold 22 away from the lower connecting mold 21, corresponding to the first engaging protrusion 421. The first engaging protrusion 421 and the first engaging groove 221 engage with each other to limit the displacement of the upper forming mold 42 in the minor axis direction of the elliptical cross-section. When the upper mold 42 descends and fits against the lower mold 22, the engaging structure ensures that they are accurately aligned in the minor axis direction, making the size and shape of the elliptical cylindrical structure formed by the upper and lower forming molds 22 more precise. This allows for better fit against the inner circumference of the hat, improving the fixing effect of the tooling on the hat and enhancing the accuracy and quality of the printing.

[0052] In some embodiments, see Figure 1 and Figure 3The bottom surface of the upper connecting mold 41 has a second locking protrusion 422 along its long axis, and the top surface of the lower connecting mold 21 has a second locking groove 222 corresponding to the second locking protrusion 422. The second locking protrusion 422 and the second locking groove 222 are inserted and engaged to limit the displacement of the upper connecting mold 41 in its own generatrix extension direction. The upper mold 4 and the lower mold 2 can also achieve precise docking in the long axis direction, ensuring the fitting accuracy of the upper mold 4 and the lower mold 2 in all directions. This improves the fixing accuracy of the tooling for the cap; enhances the stability of the entire tooling structure, and prevents the upper mold 4 from shaking or shifting in the long axis direction.

[0053] In some embodiments, see Figure 1 Multiple weight-reducing holes 5 are provided on the upper mold 4 and the lower mold 2 respectively. The presence of weight-reducing holes 5 increases the surface area of ​​the upper mold 4 and the lower mold 2, which is conducive to heat dissipation and prevents the tooling from deforming or being damaged due to excessive temperature, thus ensuring the accuracy and service life of the tooling.

[0054] In some embodiments, see Figure 1 The base 1 is equipped with a connecting block 11, which is aligned vertically with the lifting plate 33. The connecting block 11 has an internal accommodating channel with openings at the top and bottom. The lifting device 32 is located within this channel, and the lower mold 2 is connected to the side of the connecting block 11. The connecting block 11 increases the contact area between the base 1 and the lower mold 2, improving connection strength and stability. Connecting the lower mold 2 to the connecting block 11 facilitates its removal for maintenance or replacement, reducing maintenance time and costs and improving the tooling's efficiency. When the tooling is in operation, the pressure applied by the upper mold 4 to the lower mold 2 can be evenly transmitted to the base 1 through the connecting block 11, preventing structural damage caused by excessive localized stress and extending the tooling's service life. The accommodating channel formed inside the connecting block 11 allows for the installation of the lifting device 32, preventing the connecting block 11 from interfering with the installation position of the lifting device 32 and saving space.

[0055] It should be noted that the side of the connecting block 11 connected to the lower mold 2 and the side of the lifting plate 33 connected to the upper mold 4 are located in the same vertical plane.

[0056] In some embodiments, see Figure 1 , Figure 4 and Figure 5The lifting assembly 3 also includes a height limiting plate 34 and a support frame 31. The support frame 31 is mounted on the base 1, and the height limiting plate 34 is located on top of the support frame 31. The surface of the height limiting plate 34 is perpendicular to the vertical direction and is positioned above the lifting plate 33 to limit the vertical displacement of the lifting plate 33. The height limiting plate 34 is fixed in position and always positioned above the lifting plate 33. When the lifting plate 33 rises with the telescopic end of the lifting device 32, the height limiting plate 34 can limit the rise of the lifting plate 33, preventing the upper mold 4 from rising too far and causing the hat to break, thus increasing safety and preventing damage to the hat from additional factors. The support frame 31 can support the height limiting plate 34, ensuring the positional stability of the height limiting plate 34.

[0057] In some embodiments, see Figure 1 and Figure 5 The lifting assembly 3 also includes a limiting rod 35, which is vertically set and screwed to the height limiting plate 34. The bottom end of the limiting rod 35 passes through the height limiting plate 34 and can abut against the top of the lifting plate 33. The limiting rod 35 can control the maximum lifting height of the lifting plate 33 by adjusting its own position. The lifting height of the upper mold 4 can be flexibly adjusted without the need for employees to adjust the position of the height limiting plate 34, thus increasing the convenience of operation.

[0058] In some embodiments, see Figure 1 and Figure 4 The support frame 31 includes two vertical plates 312 and a support plate 311. The surface of the support plate 311 is perpendicular to the surfaces of the two vertical plates 312. The two vertical plates 312 are symmetrically arranged on both sides of the support plate 311, forming a concave structure. A height limiting plate 34 is located on the top of the support plate 311, and the height limiting plate 34 and the two vertical plates 312 are located on opposite sides of the support plate 311. The concave structure can evenly distribute the pressure and external forces from various parts of the tooling, thereby ensuring the overall stability and reliability of the support frame 31. The vertical arrangement of the vertical plates 312 and the support plate 311 increases the load-bearing capacity of the support frame 31. The height limiting plate 34 and the two vertical plates 312 being located on opposite sides of the support plate 311 provides operators with more space to move around when placing hats, printing, etc., reducing obstacles and interference during operation, and improving work efficiency and ease of operation.

[0059] In some embodiments, see Figure 1 and Figure 2The upper connecting mold 41 has a fixing hole. The cap-printing fixing fixture also includes a fastener 6, which includes a bolt with a nut. The telescopic end has a threaded hole. The bolt passes through the fixing hole and engages with the threaded hole. The nut engages with the telescopic end to clamp and fix the upper connecting mold 41. By having the bolt pass through the fixing hole and engage with the threaded hole of the telescopic end, and then using the nut to clamp and fix the upper connecting mold 41, a stable mechanical connection structure is formed, increasing connection stability and overall structural strength. The operator only needs to pass the bolt through the fixing hole, then thread it into the threaded hole of the telescopic end, and finally tighten the nut to complete the installation of the upper connecting mold 41. The installation is simple, reducing installation difficulty and time costs, improving the assembly efficiency of the fixture, and facilitating maintenance and replacement.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
