Detailed Implementation

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 and Figure 2As shown, an internal pressure frame adjustment mechanism includes: an equipment frame 1, a first mounting bracket 2, and a second mounting bracket 4. A support platform 101 is mounted on the equipment frame 1. The first mounting bracket 2 is slidably mounted on the top surface of the support platform 101. A front pressure foot 3 is mounted on the first mounting bracket 2. By controlling and driving the first mounting bracket 2, the front pressure foot 3 can be driven to reciprocate along a first direction. The first direction is referenced to the attached diagram. Figure 1 The second mounting bracket 4 is slidably mounted on the top surface of the support platform 101. A rear pressure foot 5 is mounted on the second mounting bracket 4, which is located on one side of the front pressure foot 3. The second mounting bracket 4 can be driven to move the rear pressure foot 5 back and forth in the first direction, so that the front pressure foot 3 and the rear pressure foot 5 move relatively closer or further apart. By controlling the first mounting bracket 2 to move the front pressure foot 3 back and forth in the first direction, and simultaneously controlling the second mounting bracket 4 to move the rear pressure foot 5 back and forth in the first direction, the distance between the front pressure foot 3 and the rear pressure foot 5 is automatically controlled, eliminating the need for technicians to operate. The entire adjustment process is simpler, more efficient, and the adjustment accuracy of the distance between the front pressure foot 3 and the rear pressure foot 5 is higher.

[0030] In use, when it is necessary to reduce the distance between the front presser foot 3 and the rear presser foot 5, the first mounting bracket 2 is controlled to move the front presser foot 3 forward in the first direction, while the second mounting bracket 4 is controlled to move the rear presser foot 5 in the first direction in the opposite direction. At this time, the front presser foot 3 and the rear presser foot 5 gradually move closer until the distance meets the operational requirements. When it is necessary to increase the distance between the front presser foot 3 and the rear presser foot 5, the first mounting bracket 2 is controlled to move the front presser foot 3 in the first direction in the opposite direction, while the second mounting bracket 4 is controlled to move the rear presser foot 5 in the first direction forward. At this time, the front presser foot 3 and the rear presser foot 5 gradually move further apart until the distance meets the operational requirements.

[0031] like Figure 1 and Figure 7As shown, in one embodiment of this utility model, a first transmission rack 6 is provided on the first mounting frame 2, which can reciprocate synchronously with the first mounting frame 2 along a first direction. A second transmission rack 7 is provided on the second mounting frame 4, which can reciprocate synchronously with the second mounting frame 4 along a first direction. A drive device 8 is provided on the equipment frame 1, which is preferably a stepper motor. A drive gear 9 is provided at the output end of the drive device 8. The drive gear 9 is located between the first transmission rack 6 and the second transmission rack 7, and the drive gear 9 meshes with the first transmission rack 6 and the second transmission rack 7. By synchronously meshing the drive gear 9, the first transmission rack 6 and the second transmission rack 7 are driven, ensuring that the first mounting frame 2 and the second mounting frame 4 move synchronously along the first direction. This, in turn, drives the front pressure foot 3 and the rear pressure foot 5 to perform synchronous actions of moving closer or further apart. Compared to multiple drive devices 8 driving the first mounting frame 2 and the second mounting frame 4 separately, this effectively improves the consistency of the distance adjustment between the front pressure foot 3 and the rear pressure foot 5.

[0032] In some specific embodiments, a first rack adjusting plate 10 is provided on the first mounting bracket 2 and positioned on the side of the first transmission rack 6 opposite to the drive gear 9. The first rack adjusting plate 10 is connected to the first transmission rack 6 via a first adjusting screw. By turning the first adjusting screw, the first transmission rack 6 is pushed closer to the drive gear 9 to adjust the meshing clearance between the first transmission rack 6 and the drive gear 9. This avoids problems such as loose meshing or excessive clearance caused by long-term engagement, vibration, or assembly errors between the first transmission rack 6 and the drive gear 9, ensuring that the two always maintain a stable meshing state, thereby improving the motion accuracy of the first mounting bracket 2 and the front pressure foot 3. Similarly, a second rack adjusting plate 11 is provided on the second mounting bracket 4 and positioned on the side of the second transmission rack 7 opposite to the drive gear 9. The second rack adjusting plate 11 is connected to the second transmission rack 7 via a second adjusting screw.

[0033] like Figure 3 and Figure 4As shown, in one embodiment of this utility model, two first mounting brackets 2 are provided on the equipment frame 1, that is, both first mounting brackets 2 are slidably disposed on the top surface of the support platform 101, and both first mounting brackets 2 can reciprocate along the first direction. The two first mounting brackets 2 are fixedly connected by connectors 13, so that the two first mounting brackets 2 form a whole, and assembly brackets 14 are provided at the ends of the two first mounting brackets 2. The assembly brackets 14 are connected to the front pressure foot 3 by first fasteners 15 to ensure the structural rigidity of the assembly brackets 14, so as to distribute the force generated by the front pressure foot 3 during operation, avoid deformation or displacement caused by force concentration on a single mounting bracket, and effectively ensure the straightness and stability of the assembly brackets 14 when moving along the first direction. In addition, the arrangement of two first mounting brackets 2 makes the force on the assembly brackets 14 more even, ensuring the movement accuracy of the front pressure foot 3, thereby improving the reliability of the distance adjustment between the front pressure foot 3 and the rear pressure foot 5.

[0034] In some specific embodiments, the assembly frame 14 is C-shaped overall, and its two ends are respectively connected to the corresponding first mounting brackets 2. The C-shaped assembly frame 14 has better stress stability, enabling the assembly frame 14 and the two first mounting brackets 2 to form a stable connection structure, thereby dispersing the force generated by the front pressure foot 3 during operation. Moreover, the C-shaped assembly frame 14 can reserve a certain operating space for the installation of the rear pressure foot 5, avoiding interference between the installation of the front pressure foot 3 and the rear pressure foot 5, resulting in a more reasonable structural design.

[0035] In one embodiment of this utility model, a first limiting guide rail 16 is provided on the equipment frame 1. Specifically, the first limiting guide rail 16 is provided on the top surface of the support platform 101 and extends along a first direction. A first sliding seat 17 is provided on the bottom surface of the first mounting frame 2, and the first limiting guide rail 16 is slidably connected to the first sliding seat 17. The sliding cooperation between the first limiting guide rail 16 and the first sliding seat 17 limits and corrects the movement path of the first mounting frame 2, constraining the first mounting frame 2 to move linearly along a preset first direction, preventing the first mounting frame 2 from deviating or tilting during movement, and ensuring the trajectory accuracy of the first mounting frame 2 driving the front pressure foot 3. On the other hand, the sliding cooperation between the first limiting guide rail 16 and the first sliding seat 17 can improve the smoothness of the movement of the first mounting frame 2, improve the response speed of the distance adjustment between the front pressure foot 3 and the rear pressure foot 5, prevent wear between the first limiting guide rail 16 and the first mounting frame 2, and effectively extend the service life of the first mounting frame 2.

[0036] In one embodiment of this utility model, a second limiting guide rail 18 is provided on the equipment frame 1. Specifically, the second limiting guide rail 18 is provided on the top surface of the support platform 101 and extends along a first direction. A second sliding seat 19 is provided on the bottom surface of the second mounting bracket 4, and the second limiting guide rail 18 is slidably connected to the second sliding seat 19. Similarly, the movement path of the second mounting bracket 4 is limited and corrected by the sliding cooperation between the second limiting guide rail 18 and the second sliding seat 19, constraining the second mounting bracket 4 to move in a straight line along the preset first direction, avoiding deviation or tilting of the second mounting bracket 4 during movement, and ensuring the trajectory accuracy of the movement of the rear pressure foot 5 driven by the second mounting bracket 4. On the other hand, the sliding cooperation between the second limiting guide rail 18 and the second sliding seat 19 can improve the smoothness of the movement of the second mounting bracket 4, thereby improving the response speed of the distance adjustment between the front pressure foot 3 and the rear pressure foot 5, preventing wear between the second limiting guide rail 18 and the second mounting bracket 4, and effectively extending the service life of the second mounting bracket 4.

[0037] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, a connecting frame 22 is slidably disposed on the side of the second mounting frame 4. Specifically, the connecting frame 22 is capable of reciprocating relative to the second mounting frame 4 along a second direction, the second direction being referenced in the attached diagram. Figure 1 In the Y direction, the second direction is perpendicular to the first direction. The connecting frame 22 is connected to the rear pressure foot 5 through the second fastener 25. Through the sliding cooperation between the connecting frame 22 and the second mounting frame 4, the position of the connecting frame 22 relative to the second mounting frame 4 in the second direction can be further adjusted based on the movement of the rear pressure foot 5 along the first direction driven by the second mounting frame 4. This allows for flexible adjustment of the height difference between the front pressure foot 3 and the rear pressure foot 5. The height difference can be adjusted according to the thickness, shape, or different operating conditions of the workpiece, enabling the front and rear pressure feet 5 to adapt to more diverse operating conditions and improving the versatility and adaptability of the overall internal pressure frame adjustment mechanism. Furthermore, by adjusting the height difference between the front pressure foot 3 and the rear pressure foot 5, it can be ensured that both the front and rear pressure feet 3 and 5 can simultaneously and stably adhere to the workpiece surface, avoiding uneven force on the workpiece due to inconsistent heights and improving the stability and reliability of the pressing operation.

[0038] In one embodiment of this utility model, a third limiting guide rail 20 is provided on the side of the second mounting bracket 4, extending along a second direction. A third sliding seat 21 is provided on the connecting bracket 22, and the third limiting guide rail 20 is slidably connected to the third sliding seat 21. The sliding cooperation between the third limiting guide rail 20 and the third sliding seat 21 limits and corrects the movement path of the connecting bracket 22, constraining it to move linearly along a preset second direction. This prevents the connecting bracket 22 from deviating or tilting during movement, ensuring the accuracy of the trajectory of the connecting bracket 22 driving the rear pressure foot 5 to move up and down along the second direction. Furthermore, the sliding cooperation between the third limiting guide rail 20 and the third sliding seat 21 improves the smoothness of the connecting bracket 22's movement, thereby increasing the response speed of the distance adjustment between the front pressure foot 3 and the rear pressure foot 5, preventing wear between the third limiting guide rail 20 and the connecting bracket 22, and effectively extending the service life of the connecting bracket 22.

[0039] In one embodiment of this utility model, a fixing plate 23 is provided on the side of the second mounting bracket 4, and a driving component 24 is provided on the connecting bracket 22. Preferably, the driving component 24 is a driving cylinder. The driving component 24 is connected to the fixing plate 23 through a piston rod. The driving component 24 drives the piston rod to extend and retract. The reverse force of the fixing plate 23 drives the driving component 24 to move the connecting bracket 22 up and down in the second direction, thereby realizing the automatic adjustment of the position of the connecting bracket 22 in the second direction. Compared with manual operation, it reduces labor costs and has higher adjustment accuracy, ensuring precise control of the height difference between the front pressure foot 3 and the rear pressure foot 5, and effectively improving the pressing effect of the inner pressure frame adjustment mechanism.

[0040] In one embodiment of this utility model, a reinforcing member 12 is provided on the side of the third sliding seat 21. The reinforcing member 12 is generally L-shaped, and the bottom surface of the reinforcing member 12 is connected to the top surface of the connecting frame 22. By providing a reinforcing member 12 on the side of the third sliding seat 21 and making the bottom surface of the reinforcing member 12 firmly connected to the top surface of the connecting frame 22, an additional rigid support and a stable connection can be formed between the third sliding seat 21 and the connecting frame 22, thereby improving the structural strength of the third sliding seat 21 and the connecting frame 22, ensuring the synchronicity and coordination of the movement of the third sliding seat 21 and the connecting frame 22, and thus ensuring the positional accuracy of the rear pressure foot 5 during the adjustment process along the first direction or the second direction.

[0041] The working principle of this utility model is as follows: When it is necessary to reduce the distance between the front pressure foot 3 and the rear pressure foot 5, the output end of the drive device 8 drives the drive gear 9 to rotate in the forward direction. Simultaneously, the drive gear 9 drives the first transmission rack 6 and the second transmission rack 7 to move in opposite directions along the first direction. The first transmission rack 6 synchronously drives the two first mounting brackets 2 and the front pressure foot 3 to move in the forward direction along the first direction, while the second transmission rack 7 synchronously drives the second mounting bracket 4 and the rear pressure foot 5 to move in the reverse direction along the first direction. At this time, the front pressure foot 3 and the rear pressure foot 5 gradually approach each other until the distance meets the operational requirements. When it is necessary to increase the distance between the front pressure foot 3 and the rear pressure foot 5, the output end of the drive device 8 drives the drive gear 9 to rotate in the reverse direction. Simultaneously, the drive gear 9 meshes with the first transmission rack 6 and the second transmission rack 7. The first transmission rack 6 synchronously drives the two first mounting brackets 2 and the front pressure foot 3 to move in the reverse direction along the first direction, while the second transmission rack 7 synchronously drives the second mounting bracket 4 and the rear pressure foot 5 to move in the forward direction along the first direction. At this time, the front pressure foot 3 and the rear pressure foot 5 gradually approach each other until the distance meets the operational requirements.

[0042] In summary, by controlling the first mounting bracket 2 and the second mounting bracket 4 to drive the front pressure foot 3 and the rear pressure foot 5 to reciprocate along the first direction, the front pressure foot 3 and the rear pressure foot 5 move relatively closer or further apart, automatically controlling the distance between the front pressure foot 3 and the rear pressure foot 5. The whole adjustment process is simpler and more efficient, and the adjustment accuracy of the distance between the front pressure foot 3 and the rear pressure foot 5 is higher.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
