Description

Technical Field

[0001] This utility model relates to the field of textile accessories technology, and in particular to a manual pressure roller lifting mechanism. Background Technology

[0002] A pressure roller lifting mechanism is a mechanical device that enables the pressure roller to move up and down relative to a fixed reference surface. It uses a power source to drive the actuator, which in turn drives the connecting parts to change the position of the pressure roller.

[0003] Chinese Patent Publication No. CN218642090U, published on March 17, 2023, discloses a pressing mechanism for improving the stability of fabric conveying. The mechanism is mounted on a frame and includes a pressure roller body. The pressure roller body is disposed between a first conveying roller and a second conveying roller. The pressure roller body is fitted against the side walls of the first and second conveying rollers. The pressure roller body is movably engaged with the first conveying roller and the pressure roller is movably engaged with the second conveying roller.

[0004] The existing pressure roller lifting mechanism, as described above, achieves vertical position adjustment of the pressure roller through two sets of adjustment mechanisms. In actual implementation, the two sets of adjustment mechanisms are symmetrically distributed on the frame, and the power source for both sets of adjustment mechanisms is the rotation of the adjustment blocks. Often, two operators are required to rotate the two sets of adjustment blocks simultaneously, which is quite inconvenient. Therefore, there is an urgent need to propose a corresponding manual pressure roller lifting mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a manual pressure roller lifting mechanism to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A manual pressure roller lifting mechanism includes a frame, a top frame fixedly connected to the top of the frame, a support frame and a sliding component that limits the axial position of the support frame are integrated between the two sets of vertical ends of the top frame, a tensioning pressure roller is rotatably connected to the inner wall of the support frame, and a drive rod is screwed onto the inner wall of the horizontal end of the top frame, with the bottom of the drive rod rotatably connected to the top of the support frame.

[0008] Preferably, a fixed base is fixedly connected to the top of the top frame, a rotating sleeve is rotatably connected to the outer wall of the fixed base, a pressure frame and an elastic part for maintaining the position of the pressure frame are integrated on the outer side of the rotating sleeve, and the horizontal end of the pressure frame overlaps the top of the drive rod.

[0009] Preferably, the elastic part includes a spring, the pressure frame has a U-shaped structure, and the spring is fixedly connected between the inner wall of the rotating sleeve and the bottom of the vertical end of the pressure frame.

[0010] Preferably, a rubber pad is fixedly connected to the bottom of the horizontal end of the pressure frame.

[0011] Preferably, the sliding assembly includes a sliding sleeve fixedly connected to the outer wall of the support frame, and the inner wall of the sliding sleeve is slidably connected to the outer wall of the vertical end of the top frame.

[0012] Preferably, a connecting frame is fixedly connected to the bottom of the vertical end of the top frame, and the connecting frame is fixedly connected to the outer wall of the frame via a locking rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the drive rod is rotated to engage with the inner wall of the top frame, and the bottom of the drive rod is rotated to engage with the top of the support frame. As the drive rod rises and falls, it will tension the pressure roller through the support frame, thereby lifting the pressure roller. The sliding sleeve slides synchronously along the outer wall of the vertical end of the top frame, which can limit the axial deflection of the support frame and ensure the stability of the support frame lifting. The support frame ensures that the pressure roller is subjected to uniform force. Combined with the lifting of the drive rod, it replaces the traditional method of rotating two sets of adjusting blocks at the same time, ensuring the convenience of lifting the pressure roller.

[0015] 2. In this application, after the tensioning roller is lifted by the drive rod, the pressure frame located outside the fixed seat is pulled. The vertical end of the pressure frame slides with the rotating sleeve, and the spring is stretched. Then the pressure frame is deflected, and the rotating sleeve rotates with the fixed seat until the horizontal end of the pressure frame is located at the top of the drive rod. At this time, the pressure frame is released, the spring pulls the pressure frame, and the horizontal end of the pressure frame is stably pressed against the drive rod for positioning. The friction generated therefrom can limit the axial loosening of the drive rod, thereby further ensuring the stability of the manual pressure roller lifting mechanism. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A manual pressure roller lifting mechanism includes a frame 1, a top frame 3 fixedly connected to the top of the frame 1, a support frame 5 integrated between the two sets of vertical ends of the top frame 3 and a sliding component that limits the axial position of the support frame 5, a tensioning pressure roller 6 rotatably connected to the inner wall of the support frame 5, and a drive rod 7 screwed onto the inner wall of the horizontal end of the top frame 3, with the bottom of the drive rod 7 rotatably connected to the top of the support frame 5.

[0025] Rotate the drive rod 7 to engage with the inner wall of the top frame 3. The bottom of the drive rod 7 rotates and engages with the top of the support frame 5. As the drive rod 7 rises and falls, it will tension the pressure roller 6 through the support frame 5, thereby lifting the pressure roller 6. The sliding sleeve 4 slides synchronously along the outer wall of the vertical end of the top frame 3, which can limit the axial deflection of the support frame 5 and ensure the stability of the lifting of the support frame 5. The support frame 5 ensures that the pressure roller 6 is subjected to uniform force. Combined with the lifting of the drive rod 7, it replaces the traditional method of rotating two sets of adjusting blocks at the same time, ensuring the convenience of lifting the pressure roller.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a fixed base 8 is fixedly connected to the top of the top frame 3. A rotating sleeve 10 is rotatably connected to the outer wall of the fixed base 8. A pressure frame 9 and an elastic part for maintaining the position of the pressure frame 9 are integrated on the outer side of the rotating sleeve 10. The horizontal end of the pressure frame 9 overlaps the top of the drive rod 7. The elastic part includes a spring 11. The pressure frame 9 has a U-shaped structure. The spring 11 is fixedly connected between the inner wall of the rotating sleeve 10 and the bottom of the vertical end of the pressure frame 9. After the tensioning roller 6 is lifted by the drive rod 7, the pressure frame 9 that is overlapped on the outer side of the fixed base 8 is pulled. The vertical end of the pressure frame 9 and the rotating sleeve With the sliding engagement of 10, the spring 11 is stretched, and then the pressure frame 9 is deflected. The rotating sleeve 10 rotates with the fixed seat 8 until the horizontal end of the pressure frame 9 is located at the top of the drive rod 7. At this time, the pressure frame 9 is released, and the spring 11 pulls the pressure frame 9. The horizontal end of the pressure frame 9 is stably pressed against the drive rod 7 for positioning. The friction generated by this can limit the axial loosening of the drive rod 7, thereby further ensuring the stability of the manual pressure roller lifting mechanism. A rubber pad is fixedly connected to the bottom of the horizontal end of the pressure frame 9 to ensure the stability of the contact between the pressure frame 9 and the top of the drive rod 7.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the sliding assembly includes a sliding sleeve 4 fixedly connected to the outer wall of the support frame 5. The inner wall of the sliding sleeve 4 is slidably connected to the outer wall of the vertical end of the top frame 3. The sliding sleeve 4 slides synchronously along the outer wall of the vertical end of the top frame 3, thereby limiting the axial deflection of the support frame 5 and ensuring the stability of the lifting of the support frame 5. A connecting frame 2 is fixedly connected to the bottom of the vertical end of the top frame 3, and the connecting frame 2 is fixedly connected to the outer wall of the frame 1 through a locking rod 12, thereby ensuring the ease of assembly and disassembly of the top frame 3.

[0028] Working principle: Rotating the drive rod 7 causes it to screw into the inner wall of the top frame 3. The bottom of the drive rod 7 rotates and engages with the top of the support frame 5. As the drive rod 7 rises and falls, it links with the support frame 5 to tension the pressure roller 6, thereby lifting the pressure roller 6. Simultaneously, the sliding sleeve 4 slides along the outer wall of the vertical end of the top frame 3, thus limiting the axial deflection of the support frame 5 and ensuring the stability of the lifting of the support frame 5. The support frame 5 ensures that the pressure roller 6 is subjected to uniform force. Combined with the lifting of the drive rod 7, this replaces the traditional method of simultaneously rotating two sets of adjusting blocks, ensuring the lifting of the pressure roller. For ease of use, after the tensioning roller 6 is lifted by the drive rod 7, the pressure frame 9, which rests against the outside of the fixed seat 8, is pulled. The vertical end of the pressure frame 9 slides with the rotating sleeve 10, and the spring 11 is stretched. Then the pressure frame 9 is deflected, and the rotating sleeve 10 rotates with the fixed seat 8 until the horizontal end of the pressure frame 9 is at the top of the drive rod 7. At this time, the pressure frame 9 is released, and the spring 11 pulls the pressure frame 9. The horizontal end of the pressure frame 9 is stably pressed against the drive rod 7 for positioning. The friction generated by this can limit the axial loosening of the drive rod 7, thereby further ensuring the stability of the manual pressure roller lifting mechanism.
