Description

Technical fields:

[0001] This utility model relates to the technical field of carding machines, and more specifically to a pressure roller adjustment structure at the winding roller of a carding machine. Background technology:

[0002] The carding machine is a key piece of equipment in textile production, mainly used to open, comb, remove impurities, and form slivers from fiber raw materials (such as cotton and chemical fibers), providing high-quality slivers for subsequent spinning processes. The combed sliver is wound onto a cylindrical roller, and a weighted pressure roller is typically positioned above it. This pressure roller applies pressure based on its weight, compressing the loose fiber layer into a uniform and compact sliver, providing a stable raw material for subsequent drawing and spinning processes. Currently, the two ends of the pressure roller are inserted into Y-shaped supports, which limit its position. The pressure roller can also move upwards within the slots of the supports as the sliver is wound. While its structure is simple and effectively holds the sliver, a drawback is that the pressure roller needs to be removed when the roller restarts winding the sliver, and then placed back on after the sliver is wound on the roller. This requires moving the pressure roller, which is not easy due to its weight. Therefore, a structure is needed to facilitate the removal of the pressure roller from the roller. Utility Model Content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a pressure roller adjustment structure at the winding roller of a carding machine. Its structure is simple and compact, and it can move the pressure roller away from the winding roller with relatively little effort by using the lever principle. At the same time, it can effectively position the pressure roller after it is separated from the winding roller.

[0004] A pressure roller adjustment structure at the winding roller of a carding machine includes two sets of side supports at the outlet of the carding machine. A cylindrical transverse winding roller is connected between the side supports through a bearing seat. A transverse pressure roller is pressed against the outer wall of the upper side of the winding roller. Support shafts are formed at both ends of the pressure roller. Vertical limiting arms are provided on both sides of the pressure roller. Vertical limiting grooves are formed on the limiting arms. The support shafts at both ends of the pressure roller are respectively inserted into the limiting grooves of the limiting arms. A rotating shaft is formed on one side of the top of the limiting arm. The rotating shaft passes through a triangular support plate and is fitted with an inner limiting sleeve. The support plate is fixed to the side supports.

[0005] An arc-shaped guide groove is formed on the support plate on one side of the pressure roller. One end of the guide groove passes through the front end face of the support plate, and the other end is formed with a downward positioning socket. A horizontal lever is abutted on the front end face of the support plate at the entrance of the guide groove. One end of the lever is located in front of the limiting arm, and the other end is fixed to the inclined rocker arm. An inclined adjustment groove is formed on the upper end of the rocker arm. The rotating shaft passes through the adjustment groove of the rocker arm and is fixed to the outer limiting sleeve. A horizontal handle is fixed to the lower end of the rocker arm.

[0006] A connecting shaft is formed on the other side of the top of the limiting arm, and a transverse transmission shaft sleeve is inserted between the tops of the limiting arms. The two ends of the transmission shaft sleeve are respectively sleeved on the connecting shaft of the limiting arm.

[0007] Preferably, the central axis of the pressure roller is located behind the central axis of the winding roller, and the diameter of the support shafts at both ends of the pressure roller is equal to the groove width of the upper limit groove of the limiting arm.

[0008] Preferably, the support plate is fixed to the side wall of the side support away from the roller, and the limiting arm abuts against the side end face of the support plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] This structure is simple and compact. By using the lever principle, it can move the pressure roller away from the winding roller with relatively little effort. At the same time, after the pressure roller is separated from the winding roller, it can effectively position the pressure roller, making it convenient for the winding roller to start winding the cotton sliver again.

Detailed implementation method:

[0021] Example: See Figures 1 to 2 As shown, a pressure roller adjustment structure at the winding roller of a carding machine includes two sets of side supports 1 at the outlet of the carding machine. A cylindrical transverse winding roller 2 is connected between the side supports 1 through a bearing seat. A transverse pressure roller 3 is pressed against the outer wall of the upper side of the winding roller 2. Support shafts 31 are formed at both ends of the pressure roller 3. Vertical limiting arms 4 are provided on both sides of the pressure roller 3. Vertical limiting grooves 41 are formed on the limiting arms 4. The support shafts 31 at both ends of the pressure roller 3 are respectively inserted into the limiting grooves 41 of the limiting arms 4. A rotating shaft 42 is formed on one side of the top of the limiting arm 4. The rotating shaft 42 passes through a triangular support plate 5 and is fitted with an inner limiting sleeve 6. The support plate 5 is fixed to the side supports 1.

[0022] An arc-shaped guide groove 51 is formed on the support plate 5 on one side of the pressure roller 3. One end of the guide groove 51 passes through the front end face of the support plate 5, and the other end is formed with a downward positioning insertion port 52. A horizontal lever 9 is abutted on the front end face of the support plate 5 at the entrance of the guide groove 51. One end of the lever 9 is located in front of the limiting arm 4, and the other end is fixed to the inclined rocker arm 7. An inclined adjustment groove 71 is formed at the upper end of the rocker arm 7. The rotating shaft 42 passes through the adjustment groove 71 of the rocker arm 7 and is fixed to the outer limiting sleeve 8. A horizontal handle 10 is fixed to the lower end of the rocker arm 7.

[0023] A connecting shaft is formed on the other side of the top of the limiting arm 4, and a transverse transmission shaft sleeve 12 is inserted between the tops of the limiting arms 4. The two ends of the transmission shaft sleeve 12 are respectively sleeved on the connecting shaft of the limiting arm 4.

[0024] The central axis of the pressure roller 3 is located behind the central axis of the winding roller 2. The diameter of the support shaft 31 at both ends of the pressure roller 3 is equal to the groove width of the upper limit groove 41 of the limit arm 4. Only then can the lever 9 push the limit arm 4 to rotate backward and upward, so that the pressure roller 3 can be separated from the winding roller 2.

[0025] The bracket plate 5 is fixed to the side wall of the side bracket 1 on the side away from the roller 2, and the limiting arm 4 abuts against the side end face of the bracket plate 5.

[0026] The limiting arm 4 is made of magnetic material. A magnet 13 is attached to the front end of the limiting arm 4. The magnet 13 is fixed to the support plate 5. The magnet 13 can realize the stable vertical setting of the limiting arm 4, which is beneficial for the pressure roller 3 to always effectively press on the cotton roll when the roller 2 winds the cotton roll.

[0027] The lever 9 is a round rod. The width of the guide groove 51 and the width of the positioning socket 52 on the bracket plate 5 are not less than the diameter of the lever 9. The distance from the lever 9 to the entrance of the guide groove 51 is not greater than the length of the adjustment groove 71 on the rocker arm 7. When the pressure roller 3 is moved backward, the lever 9 needs to enter the guide groove 51. Therefore, the above-mentioned size limit is required.

[0028] The diameter of the rotating shaft 42 is equal to the width of the adjusting groove 71 on the rocker arm 7, and the rotating shaft 42 is located at the upper end of the adjusting groove 71.

[0029] A tubular handle sleeve 11 is pivotally connected to the handle 10 of the rocker arm 7. The handle sleeve 11 can be rotated to facilitate the pushing of the rocker arm 7.

[0030] A gap is provided between the drive shaft sleeve 12 and the limiting arm 4, and the distance between the drive shaft sleeve 12 and the limiting arm 4 is less than half the length of the connecting shaft; the inner diameter of the drive shaft sleeve 12 is equal to the diameter of the connecting shaft, so that although the drive shaft sleeve 12 can move, it will not detach from the limiting arm 4.

[0031] Working principle: This structure is a pressure roller adjustment structure at the winding roller of a carding machine. It connects and sets the pressure roller 3 on the limiting arm 4. Based on the gravity of the pressure roller 3, it can move and adjust within the limiting groove 41, enabling the pressure roller 3 to effectively press and hold the winding roller 2; Figure 1 , 2 As shown;

[0032] However, when the winding roller 2 starts winding the cotton sliver again, the pressure roller 3 needs to disengage from the winding roller 2. The handle 10 can be used to move the rocker arm 7 upward first, so that the lever 9 enters the entrance of the guide groove 51. Then, the rocker arm 7 is rotated backward by using the rotating shaft 42 as the fulcrum. The lever 9 will then move the limiting arm 4 to rotate, so that the pressure roller 3 disengages from the winding roller 2. Compared with directly picking up the pressure roller 3, using the rocker arm 7 as the lever arm and the rotating shaft 42 as the fulcrum, the force of driving the rocker arm 7 is much less than the force of picking up the pressure roller 3, which can save a lot of effort.

[0033] When the lever 9 moves to the end of the guide groove 51, pulling the rocker arm 7 downwards allows the lever 9 to enter the positioning socket 52. The positioning socket 52 then restricts the rotation of the rocker arm 7, thereby positioning the pressure roller 3 to disengage from the winding roller 2. Figure 3 , 4 As shown.

[0034] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
