Description

Technical Field

[0001] This utility model relates to the field of pressure plate adjustment technology for circular knitting machines, and in particular to a circular knitting machine with an adjustable pressure plate. Background Technology

[0002] A circular knitting machine, also known as a circular weft knitting machine or a circular weft knitting machine, comes in two types: single-sided and double-sided. In the double-sided circular knitting machine, the pressure plate is mounted on a cam seat to press the needles at the required positions, thereby improving the knitting quality.

[0003] A search revealed that CN217677995U discloses a double-sided circular knitting machine with adjustable pressure plates, comprising a triangular base and a first horizontal plate. The upper part of the triangular base has a groove, and the first horizontal plate is fixed to the inner wall of the groove. The aforementioned patent states that "although the pressure plates on the circular knitting machine can be used, it is not conducive to quickly adjusting the lateral and longitudinal positions of the pressure plates, thus reducing the effectiveness of use." To better address the above problems, promote the development of industry technology, and enhance core competitiveness, this application proposes a new structural design that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a circular knitting machine with an adjustable pressure plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable pressure plate circular knitting machine includes a triangular base mounted on the machine. The top of the triangular base has a groove, and the bottom of the groove is rotatably connected to a threaded sleeve via a bearing. A lead screw is threaded into the threaded sleeve, and a worm gear is fixedly connected to the top of the threaded sleeve, with the lead screw passing through a through hole in the worm gear. A worm gear meshing with the worm gear is rotatably connected to the groove via a bearing. A connecting assembly for manually rotating the worm gear is provided on one side of the triangular base. A lifting plate is fixedly connected to the top of the lead screw. Two limiting strips are fixedly connected to the upper surface of the lifting plate, and a pressure plate is provided between the two limiting strips. A sliding groove is provided on one side of each of the two limiting strips. Slider blocks that move along the groove direction are fixedly connected to both sides of the pressure plate. A locking assembly for fixing the sliders is provided within the sliding groove.

[0007] As a further embodiment of this utility model, the connecting component includes a mounting hole, which is opened on one side of the triangular seat and is connected to the groove. A semi-threaded screw fixed to the worm gear is provided in the mounting hole.

[0008] As a further embodiment of this utility model, an annular groove is provided in the mounting hole, and a key ring is rotatably connected in the annular groove. The semi-threaded screw passes through the key ring and is fixed to the key ring.

[0009] As a further embodiment of this invention, a locking nut is threaded onto the outer side of the semi-threaded screw, located outside the mounting hole.

[0010] As a further embodiment of this utility model, the locking assembly includes a locking screw, which is disposed in the slide groove. A threaded hole is provided on one side of the slider, and the locking screw is threadedly connected to the threaded hole.

[0011] As a further embodiment of this utility model, the bottom of the lifting plate is fixedly connected to two symmetrically distributed support plates, and guide blocks are fixedly connected to one side of each of the two support plates in opposite directions.

[0012] As a further embodiment of this utility model, guide grooves are provided on both sides of the groove, and the guide block is slidably connected to the guide groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using the worm gear, worm, slider, and groove in combination, rotating the worm gear and meshing with the worm will cause the lead screw to move upward. The lead screw will push the lifting plate upward, thereby moving the pressure plate upward. At the same time, the pressure plate can move within the groove via the slider, thus allowing for rapid adjustment of the lateral and longitudinal positions of the pressure plate. Furthermore, through the transmission of the threaded sleeve and the lead screw, the longitudinal position of the pressure plate can be adjusted more precisely, improving the performance.

[0015] 2. By using a locking assembly, the lateral position of the pressure plate is locked and fixed by screws, allowing for arbitrary adjustment of the lateral position of the pressure plate without restriction, thus further improving the performance. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-4A circular knitting machine with an adjustable pressure plate includes a triangular base 1 mounted on the machine. The top of the triangular base 1 has a groove 18. A threaded sleeve 5 is rotatably connected to the bottom of the groove 18 via a bearing. A lead screw 15 is threaded into the threaded sleeve 5. A worm gear 16 is bolted to the top of the threaded sleeve 5, and the lead screw 15 passes through a through hole in the worm gear 16. A worm 17, meshing with the worm gear 16, is rotatably connected to the groove 18 via a bearing. A connecting assembly for manually rotating the worm 17 is provided on one side of the triangular base 1. The connecting assembly includes a mounting hole 7, located on one side of the triangular base 1 and communicating with the groove 18. A semi-threaded screw 9, fixed to the worm 17, is located within the mounting hole 7. An annular groove 10 is formed within the mounting hole 7, and a key ring 8 is rotatably connected within the annular groove 10. The semi-threaded screw 9 passes through and is fixed to the key ring 8. The outer side of the semi-threaded screw 9 is threaded outside the mounting hole 7. The device includes a locking nut 2 and a lifting plate 3 welded to the top of the lead screw 15. Two limit strips 13 are bolted to the upper surface of the lifting plate 3, and a pressure plate 4 is positioned between the two limit strips 13. When the longitudinal position needs adjustment, the semi-threaded screw 9 is rotated, causing the worm gear 17 to rotate. The worm gear 17 meshes with the worm wheel 16, causing the worm wheel 16 to rotate. The worm wheel 16 then rotates the threaded sleeve 5. During rotation, the threaded sleeve 5 meshes with the lead screw 15, causing the lead screw 15 to move upwards. The lead screw 15 pushes the lifting plate 3 upwards, which in turn moves the pressure plate 4 upwards, thus changing the longitudinal position of the pressure plate 4. The locking nut 2 is then tightened to lock the semi-threaded screw 9, ensuring the stability of the longitudinal position adjustment of the pressure plate 4. Furthermore, through the transmission of the threaded sleeve 5 and the lead screw 15, the longitudinal position of the pressure plate 4 can be adjusted more precisely, improving the performance.

[0023] In this invention, each of the two limiting strips 13 has a sliding groove 14 on one side. Both sides of the pressure plate 4 are fixed with bolts to sliders 19 that move along the groove of the sliding groove 14. A locking assembly for fixing the sliders 19 is provided within the sliding groove 14. The locking assembly includes a locking screw 20, which is located within the sliding groove 14. A threaded hole 21 is provided on one side of the slider 19. The locking screw 20 is threaded into the threaded hole 21, and the flat surface of the locking screw 20 contacts the limiting strip 13. When the lateral position needs to be adjusted, the locking screw 20 is loosened, allowing the pressure plate 4 to move along the sliding groove 14 via the slider 19, thus changing the lateral position of the pressure plate 4. Then, the locking screw 20 is tightened to lock the pressure plate 4, thereby fixing its lateral position and enabling adjustment of the lateral position of the pressure plate 4. Furthermore, the lateral position of the pressure plate 4 can be adjusted arbitrarily, ensuring that the adjustment is not restricted and further improving the usability.

[0024] In particular, the bottom of the lifting plate 3 is fixed with two symmetrically distributed support plates 12 by bolts. Guide blocks 6 are welded to one side of the two support plates 12 in opposite directions. Guide grooves 11 are opened on both sides of the groove 18. The guide blocks 6 are slidably connected to the guide grooves 11. The lifting plate 3 will drive the support plates 12 to move upward along the guide grooves 11 through the guide blocks 6, thereby ensuring that the lifting plate 3 moves vertically upward.

[0025] Working principle: When the longitudinal position needs to be adjusted, rotate the semi-threaded screw 9. The semi-threaded screw 9 will drive the worm 17 to rotate. The worm 17 meshes with the worm wheel 16, causing the worm wheel 16 to rotate. The worm wheel 16 will drive the threaded sleeve 5 to rotate. During the rotation of the threaded sleeve 5, it meshes with the lead screw 15, causing the lead screw 15 to move upward. The lead screw 15 will push the lifting plate 3 to move upward. The lifting plate 3 will drive the support plate 12 to move upward along the guide groove 11 through the guide block 6, thus ensuring that the lifting plate 3 moves vertically upward. The lifting plate 3 will then drive the pressure plate 4 to move upward, thereby changing the longitudinal position of the pressure plate 4. Then, tighten the locking nut 2 to adjust the semi-threaded screw 9. The locking mechanism ensures the stability of the longitudinal position adjustment of the pressure plate 4. Furthermore, the longitudinal position of the pressure plate 4 can be precisely adjusted via the threaded sleeve 5 and the lead screw 15, improving its usability. When the lateral position needs adjustment, the locking screw 20 is loosened, allowing the pressure plate 4 to move along the slide groove 14 via the slider 19, thus changing its lateral position. The locking screw 20 is then tightened to lock the pressure plate 4, fixing its lateral position and enabling adjustment of the pressure plate 4's lateral position. This allows for arbitrary adjustment of the pressure plate 4's lateral position without restriction, further improving its usability.

[0026] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
