Description

Technical Field

[0001] This application belongs to the field of hat processing technology, specifically relating to a heat-resistant fixture for a hat top pre-pressing flattening machine and a hat top pre-pressing flattening machine. Background Technology

[0002] Cotton hats, especially fleece hats, are widely used in winter due to their high warmth retention. To ensure quality and warmth retention, the top of the hat is made of three layers of cotton fabric. The thickness of the three layers of cotton fabric is too great to be directly sewn with a sewing machine. It needs to be pre-processed and flattened with a pre-pressing machine to squeeze the cotton layers and facilitate processing.

[0003] The working principle of the hat top pre-pressing machine is to clamp the hat top with the upper and lower molds, and heat the hat top with the upper mold to pre-press the three layers of cotton fabric on the hat top. In the whole process, the employee needs to put the hat on the lower mold. However, when changing hats, the employee is likely to touch the upper mold. The upper mold is hot and can easily burn the employee, which is a safety hazard and can cause a serious accident. When changing hats, the employee needs to deliberately avoid the upper mold, resulting in a small operating space and great limitations on the employee's operation, which affects the efficiency of the change. Utility Model Content

[0004] This application provides an anti-scalding fixture and a hat top pre-pressing machine, which aims to solve the technical problems in the prior art where employees are prone to accidentally touching the high-temperature upper mold when changing hats, which poses a safety hazard, and where the employee's operating space is limited.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a heat-resistant fixture for a cap pre-compression flattening machine is provided, which is installed on the top support of the pre-compression flattening machine and includes:

[0007] The connecting frame connects to the top support of the pre-compression leveling machine;

[0008] A protective plate includes a horizontal unit and a vertical unit. The top of the vertical unit is connected to the connecting frame. One end of the horizontal unit is hinged to the bottom of the vertical unit, with the hinge axis perpendicular to the horizontal direction. The vertical unit and the horizontal unit together form an isolation space for accommodating the upper mold of a pre-compression leveling machine.

[0009] A connecting component connects the horizontal unit and the vertical unit respectively.

[0010] In conjunction with the first aspect, in one possible implementation, the horizontal unit includes a swing plate, one end of which is hinged to the bottom of the vertical unit, with the hinge axis parallel to the vertical direction.

[0011] In conjunction with the first aspect, in one possible implementation, the bottom of the swing plate is provided with a cushioning pad.

[0012] In conjunction with the first aspect, in one possible implementation, the vertical unit includes a first plate and several second plates, the top of the first plate and the top of the several second plates are respectively connected to the connecting frame, the first plate and the several second plates are sequentially connected around the upper mold axis of the pre-pressing machine, the bottom of the first plate is hinged to the horizontal unit, and the first plate, the several second plates and the horizontal unit enclose the isolation space.

[0013] In conjunction with the first aspect, in one possible implementation, the upper surface of the horizontal unit can abut against the first plate and a plurality of the second plates respectively;

[0014] The connecting assembly includes a limiting pin and a locking plate. The locking plate is located on the outside of the second plate and has a locking hole. The horizontal unit has a limiting hole along its own thickness direction corresponding to the locking hole. The limiting pin passes through the locking hole and the limiting hole sequentially from top to bottom to lock the horizontal unit and the second plate.

[0015] In conjunction with the first aspect, in one possible implementation, the connecting frame includes:

[0016] Multiple connecting rods are connected to the top support of the pre-compression leveling machine, respectively;

[0017] A circular guide rail, the bottom of which is connected to the top ends of a plurality of connecting rods, the guide rail having an upward-opening guide ring groove; and

[0018] Multiple pulleys are connected to the top of the vertical unit, and each of the multiple pulleys rolls into the guide ring groove.

[0019] In conjunction with the first aspect, in one possible implementation, the vertical unit is provided with a handle on its outer side.

[0020] The anti-scalding fixture for the hat pre-pressing machine provided in this application, compared with existing technologies, separates the upper mold of the pre-pressing machine from the employee's operating area by setting up a protective plate. The horizontal and vertical units of the protective plate create an isolation space, preventing employees from directly contacting the high-temperature upper mold during hat changing and other operations. This reduces the risk of burns, ensures employee safety, and prevents accidents. With the horizontal and vertical units separating the upper mold, employees can operate from any position below the horizontal unit, expanding the operating space. Touching the horizontal unit with their hands will not pose a safety hazard, reducing operational limitations and improving the efficiency of hat changing and other operations. After the employee changes the hat, rotating the horizontal unit to the outside of the vertical unit allows the lower and upper molds to close normally and clamp the hat. The horizontal and vertical units do not interfere with normal operation, increasing ease of use.

[0021] Secondly, a cap top pre-compression flattening machine is provided, comprising:

[0022] Workbench;

[0023] The lower mold is vertically and adjustablely connected to the upper surface of the worktable.

[0024] A support frame is mounted on the upper surface of the workbench, and a horizontal support rod is provided at the top of the support frame;

[0025] An upper mold, connected to the bottom of the horizontal support rod, is aligned vertically with the lower mold, and the upper mold is a heat-conducting component; and

[0026] As in any of the above possible implementations, the anti-scalding fixture for the hat top pre-pressing machine is such that the connecting frame in the anti-scalding fixture is connected to the horizontal support rod.

[0027] In conjunction with the second aspect, in one possible implementation, the cap pre-pressing flattening machine further includes a lifting device, which is disposed on the worktable, with the top of the lifting device forming a lifting end, and the lifting end being connected to the bottom of the lower mold.

[0028] In conjunction with the second aspect, in one possible implementation, the cap pre-pressing machine further includes an electric heating unit disposed on the upper mold and in contact with the upper mold.

[0029] Compared with existing technologies, the hat pre-pressing flattening machine provided in this application, by setting up a protective plate, uses the horizontal and vertical units of the protective plate to form an isolation space, separating the upper mold of the pre-pressing flattening machine from the employee's operating area. This prevents employees from directly contacting the high-temperature upper mold during hat changing and other operations, thereby reducing the risk of burns, ensuring employee safety, and preventing accidents. After the horizontal and vertical units separate the upper mold, employees can operate from any position below the horizontal unit, expanding the operating space. Touching the horizontal unit with their hands will not pose a safety hazard, reducing operational limitations and improving the efficiency of hat changing and other operations. After the employee changes the hat, rotating the horizontal unit to the outside of the vertical unit allows the lower and upper molds to close normally and clamp the hat. The horizontal and vertical units do not affect normal operation, increasing ease of use. The lower mold is vertically and adjustable to the upper surface of the worktable, allowing the pre-pressing machine to be adjusted according to different styles or thicknesses of cotton hat tops for better coordination with the upper mold for pre-pressing. The upper mold, acting as a heat-conducting component, heats the hat top after clamping it, achieving heat-setting and pre-pressing of the three layers of cotton fabric on the hat top, ensuring product quality and insulation performance. The connecting frame is connected to the horizontal support rod, ensuring the anti-scalding fixture is securely installed on the pre-pressing machine without shaking or shifting during machine operation, guaranteeing its continuous and effective function.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0053] It should be noted that the terms "length," "width," "height," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the application. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0054] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "linking," "fixing," and "setting" should be interpreted broadly.

[0057] Please refer to the following: Figures 1 to 9 The anti-scalding fixture for the pre-pressing machine provided in this application is described below. The anti-scalding fixture is installed on the top support of the pre-pressing machine and includes a connecting frame 1, a protective plate 2, and a connecting assembly 3. The connecting frame 1 is connected to the top support of the pre-pressing machine; the protective plate 2 includes a horizontal unit 22 and a vertical unit 21. The top of the vertical unit 21 is connected to the connecting frame 1, and one end of the horizontal unit 22 is hinged to the bottom of the vertical unit 21, with the hinge axis perpendicular to the horizontal direction. The vertical unit 21 and the horizontal unit 22 together form an isolation space for accommodating the upper mold 7 of the pre-pressing machine; the connecting assembly 3 connects the horizontal unit 22 and the vertical unit 21 respectively.

[0058] It should be noted that the horizontal unit 22 has a protective state that abuts against the bottom of the vertical unit 21 and remains horizontal, and also has a clearance state in which the horizontal unit 22 moves to the outside of the vertical unit 21. When the employee is changing hats, the horizontal unit 22 remains in the protective state; before the hat is flattened, the horizontal unit 22 rotates to the clearance state, and the lower mold 5 rises to dock with the upper mold 7 to process the hat.

[0059] It should be noted that after the pre-pressing operation, the thickness of the hat top is reduced, making it easier for employees to sew with a sewing machine, which in turn facilitates subsequent hat processing.

[0060] The anti-scalding fixture for the hat pre-pressing machine provided in this embodiment, compared with the prior art, uses a protective plate 2. The horizontal unit 22 and vertical unit 21 of the protective plate 2 enclose a space to isolate the upper mold 7 of the pre-pressing machine from the employee's operating area. This prevents employees from directly contacting the high-temperature upper mold 7 during hat changing and other operations, thus reducing the risk of burns, ensuring employee safety, and preventing accidents. After the horizontal unit 22 and vertical unit 21 separate the upper mold 7, employees can operate from any position below the horizontal unit 22, increasing operating space. Touching the horizontal unit 22 will not cause safety hazards, reducing operational limitations and improving the efficiency of hat changing and other operations. After the employee changes the hat, rotating the horizontal unit 22 to the outside of the vertical unit 21 allows the lower mold 5 and upper mold 7 to close and clamp the hat normally. The horizontal unit 22 and vertical unit 21 do not affect normal operation, increasing ease of use.

[0061] In some embodiments, see Figures 1 to 6 The horizontal unit 22 includes a swing plate, one end of which is hinged to the bottom of the vertical unit 21, with the hinge axis parallel to the vertical direction. The swing plate can swing flexibly around the hinge point, providing clearance space when the lower mold 5 and the upper mold 7 are closed. The design of the swing plate is relatively simple, and it is easy to manufacture and install.

[0062] In practice, the upper surface of the swing plate can abut against the bottom of the vertical unit 21 to avoid gaps between the swing plate and the vertical unit 21 on the horizontal plane.

[0063] In practice, the horizontal unit 22 can be made of a circular plate, a rectangular plate, or a polygonal plate, depending on the needs of the employees, which reduces the manufacturing difficulty.

[0064] It should be noted that the swing plate is made of iron plate, resulting in a small overall mass. When the swing plate is circular, its radius is between 10 and 15 cm. It can be stably connected to the bottom of the vertical unit 21 through the hinge point and connecting component 3, and will not bend due to its own weight during use.

[0065] In some embodiments, a cushioning pad is provided at the bottom of the swing plate. The cushioning pad prevents collision damage. When an employee accidentally bumps into the swing plate during operation, the cushioning pad can buffer the impact, reducing damage to the upper mold 7, the swing plate, and the entire anti-scalding workwear, and reducing the pain felt by the person from the impact. Furthermore, the cushioning pad can absorb some of the energy generated by the collision, reducing collision noise.

[0066] In some embodiments, see Figures 1 to 6The vertical unit 21 includes a first plate 211 and several second plates 212. The top of the first plate 211 and the top of the several second plates 212 are respectively connected to the connecting frame 1. The first plate 211 and the several second plates 212 are sequentially connected around the axis of the upper mold 7 of the pre-pressing machine. The bottom of the first plate 211 is hinged to the horizontal unit 22. The first plate 211, the several second plates 212 and the horizontal unit 22 enclose an isolation space.

[0067] As a hinged embodiment of the first plate 211 and the swing plate, a hinge rod is provided on the outer periphery of the swing plate, and a hinge seat is provided on the bottom outer side of the first plate 211. The hinge seat and the hinge rod are hinged together.

[0068] In practice, the protective components only need to be anti-scalding and limiting on the front and bottom plates of the pre-pressing machine. Preferably, there are two second plates 212, which are located on both sides of the first plate 211 respectively. The second plate 212 is inclined relative to the first plate 211, for example, forming a half hexagonal ring shape.

[0069] In practice, the first plate 211 and the second plate 212 may have the same shape or different shapes. They may both be rectangular plates or both be curved plates.

[0070] As another embodiment of the second plate 212, the second plate 212 is provided as one piece, and there is an included angle between the surfaces of the first plate 211 and the second plate 212. The first plate 211, the second plate 212 and the swing plate enclose and form an isolation space.

[0071] The vertical unit 21 provided in this embodiment is simple to manufacture. The first plate 211 and several second plates 212 are sequentially connected around the axis of the upper mold 7, and together with the horizontal unit 22, they form an isolation space, separating the high-temperature upper mold 7 from the operator, preventing the operator from accidentally coming into contact with the high-temperature upper mold 7 during operation, and ensuring the operator's safety. The first plate 211 and the second plate 212 are sequentially connected around the axis of the upper mold 7. According to the shape and position of the upper mold 7, the surrounding space is reasonably utilized to form an isolation space, providing a relatively safe operating space for the operator and improving the convenience of operation to a certain extent.

[0072] In some embodiments, see Figure 1 and Figure 3The upper surface of the horizontal unit 22 can abut against the first plate 211 and several second plates 212 respectively. The connecting component 3 includes a limiting pin 31 and a locking plate 32. The locking plate 32 is located on the outside of the second plate 212 and has a locking hole. The horizontal unit 22 has a limiting hole corresponding to the locking hole along its own thickness direction. The limiting pin 31 passes through the locking hole and the limiting hole sequentially from top to bottom to lock the horizontal unit 22 and the second plate 212. By opening a locking hole on the second plate 212 and setting a corresponding limiting hole and limiting pin 31 on the horizontal unit 22, the horizontal unit 22 and the second plate 212 can be locked. The limiting pin 31 enhances the stability of the entire anti-scalding fixture structure, ensuring that the components will not loosen due to vibration or other factors during the operation of the pre-pressing flattening machine, maintaining the integrity of the isolation space, and continuously and effectively preventing operators from contacting the high-temperature upper mold 7. When the anti-scalding fixture needs to be adjusted or maintained, the locking of the horizontal unit 22 and the second plate 212 can be released by loosening the limit pin 31, which increases the flexibility of use.

[0073] In some embodiments, see Figure 8 The connecting frame 1 includes multiple connecting rods 11, annular guide rails 12, and multiple pulleys 13. The connecting rods 11 are connected to the top support of the pre-pressing machine; the bottom of the guide rails 12 are connected to the tops of the connecting rods 11, and the guide rails 12 have upward-opening guide ring grooves; the multiple pulleys 13 are connected to the top of the vertical unit 21, and the multiple pulleys 13 are in rolling engagement with the guide ring grooves. The multiple connecting rods 11, connected to the top support of the pre-pressing machine, provide a stable support base for the guide rails 12. The first plate 211 and the second plate 212 are connected to the guide rails 12 via the pulleys 13, preventing them from easily shaking or shifting, maintaining the stability of their relative position with the pre-pressing machine, thus better fulfilling their isolation function and preventing operators from accidentally contacting the high-temperature upper mold 7. The vertical unit 21 can roll along the guide rails 12. During the operation of the pre-pressing machine, when it is necessary to adjust the position of the isolation space to adapt to different operational needs, the vertical unit 21 can be rolled to a suitable position in the guide ring groove by the pulley 13, so as to achieve relatively flexible positioning adjustment. The first plate 211 and the second plate 212 can be rotated before mold closing, so that workers can intuitively observe the mold closing accuracy and the flattening effect of the cap.

[0074] In some embodiments, see Figure 8 A handle 23 is provided on the outside of the vertical unit 21. The handle 23 facilitates manual operation of the vertical unit 21 by the operator. By holding the handle 23, the operator can better control the relative position of himself with the high-temperature upper mold 7 and other components, increasing the convenience of operation.

[0075] Based on the same inventive concept, see [reference] Figure 1 and Figure 2This application also provides a hat top pre-pressing and flattening machine, including a worktable 4, a lower mold 5, a support frame 6, an upper mold 7, and a hat top pre-pressing and flattening machine anti-scalding fixture as described in any of the above embodiments. The lower mold 5 is vertically and flexibly connected to the upper surface of the worktable 4; the support frame 6 is mounted on the upper surface of the worktable 4, and a horizontal support rod 61 is provided at the top of the support frame 6; the upper mold 7 is connected to the bottom of the horizontal support rod 61, and the upper mold 7 and the lower mold 5 are aligned vertically, with the upper mold 7 being a heat-conducting component; the connecting frame 1 in the hat top pre-pressing and flattening machine anti-scalding fixture is connected to the horizontal support rod 61.

[0076] In practice, the connecting rod 11 in the connecting frame 1 is vertically mounted on the horizontal support rod 61 to support the guide rail 12.

[0077] Compared with existing technologies, the hat pre-pressing flattening machine provided in this application, by setting up a protective plate 2, uses the horizontal unit 22 and vertical unit 21 of the protective plate 2 to form an isolation space, separating the upper mold 7 of the pre-pressing flattening machine from the employee's operating area. This prevents employees from directly contacting the high-temperature upper mold 7 during hat changing and other operations, thereby reducing the risk of burns, ensuring employee safety, and preventing accidents. After the horizontal unit 22 and vertical unit 21 separate the upper mold 7, employees can operate from any position below the horizontal unit 22, increasing the operating space. Touching the horizontal unit 22 will not cause a safety hazard, reducing operational limitations and improving the efficiency of hat changing and other operations. After the employee changes the hat, rotating the horizontal unit 22 to the outside of the vertical unit 21 allows the lower mold 5 and upper mold 7 to close and clamp the hat normally. The horizontal unit 22 and vertical unit 21 do not affect normal operation, increasing ease of use. The lower mold 5 is vertically and adjustable to the upper surface of the worktable 4, allowing the pre-pressing machine to be adjusted according to different styles or thicknesses of cotton hat tops to better cooperate with the upper mold 7 for pre-pressing the hat tops. The upper mold 7, as a heat-conducting component, can heat the hat top after clamping it, thus achieving the heat-setting and pre-pressing function of the three layers of cotton fabric on the hat top, ensuring product quality and heat insulation performance. The connecting frame 1 is connected to the horizontal support rod, ensuring that the anti-scalding fixture can be stably installed on the pre-pressing machine without shaking or shifting during machine operation, guaranteeing the continuous and effective function of the anti-scalding fixture.

[0078] In some embodiments, see Figure 1 and Figure 8The cap top pre-pressing machine also includes a lifting device 8, which is located on the worktable 4. The top of the lifting device 8 forms a lifting end, which is connected to the bottom of the lower mold 5. The lifting device 8 on the worktable 4 precisely controls the lifting and lowering of the lower mold 5. This allows the lower mold 5 to be accurately aligned vertically with the upper mold 7, ensuring the processing accuracy of the cap top during the pre-pressing process and improving the stability of product quality. The lifting device 8 provides a stable and reliable power source for the lifting and lowering operation of the lower mold 5, and also improves the convenience and smoothness of the entire pre-pressing machine operation.

[0079] In practice, the lifting device 8 can be a cylinder or a telescopic motor.

[0080] In some embodiments, see Figure 1 and Figure 2 The cap pre-compression flattening machine also includes an electric heating unit 9, which is located on and in contact with the upper mold 7. The electric heating unit 9 can provide a stable heat source for the upper mold 7, enabling the upper mold 7 to reach a suitable temperature, thereby meeting the thermal conditions required for the cap material during the pre-compression process.

[0081] In practice, the electric heating unit 9 can be a heating rod or an electric heating plate, both of which are electrically heated components. The electric heating unit 9 is attached to the upper mold 7 to conduct heat to the upper mold 7, which facilitates the hot pressing and flattening operation of the top of the cap.

[0082] 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.
