Description

Technical Field

[0001] The utility model relates to the technical field of spinning machines, in particular to a roller pressure device for a spinning machine. Background Art

[0002] Hemp fiber refers to fibers obtained from various hemp plants, including bast fibers from the cortex of annual or perennial herbaceous dicotyledonous plants and leaf fibers from monocotyledonous plants. The main bast fiber crops are ramie, jute, hemp, hemp, flax, ramie and kenaf. At present, hemp fiber products are increasingly recognized by people, so the market share of hemp fabrics is also increasing year by year. In the production process of hemp fabrics, the sisal leaves of sisal hemp need to be scraped to obtain hemp fibers, and then the hemp fibers need to be spun, and finally the hemp yarn spun into yarn can be woven. However, due to the relatively hard material of hemp fiber, the yarn twist is insufficient and sometimes the yarn is uneven when the rollers are used in the spinning production. Then research found that this is because the yarn is too hard to fully fit the roller rod for roller rotation; and once the pressure roller is added, the appropriate pressure cannot be controlled, which will cause the yarn to break frequently.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that the patent document with application number CN202120784480.0 disclosed a spinning machine roller pressure device. The above patent still has some problems in actual use. The most obvious one is that the method of adjusting the pressure between the pressure roller and the roller rod by rotating the threaded rod is time-consuming and labor-intensive, which is not conducive to adjusting the pressure between the pressure roller and the roller rod.

[0005] Therefore, we proposed a spinning machine roller pressure device to solve the above-mentioned drawbacks. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and provides a spinning machine roller pressure device.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a spinning machine roller pressure device, including a carrier frame, a servo motor is fixedly installed on the top surface of the carrier frame, and a screw is installed on the output end of the servo motor, and a moving block is used in conjunction with the surface of the screw, a guide rod is fixedly installed on one side of the inner wall of the carrier frame, and the surface of the guide rod is slidably connected to the guide block, a lifting seat is provided inside the carrier frame, and a through hole is provided on the surface of the lifting seat, the guide block and the moving block are both fixedly connected in the through hole, a roller rod is fixedly installed on the inner bottom surface of the carrier frame, a pressure roller is detachably installed on the lifting seat through a bracket, and a pressure sensor is installed on the pressure roller.

[0008] Preferably, the bracket is plugged into a socket reserved on the surface of the lifting seat, a positioning groove is provided on the surface of the bracket, and a positioning rod is inserted into the positioning groove, a storage groove is provided inside the lifting seat, and a spring is fixedly installed on the inner wall of the storage groove, one end of the spring is installed with a rack, and one end of the rack is fixedly connected to the positioning rod, a gear is rotatably connected to the lifting seat, and the gear is engaged with the rack, and a handle is installed at one end of the gear.

[0009] Preferably, a control panel is fixedly mounted on one side surface of the carrier, and the control panel is electrically connected to the servo motor and the pressure sensor via wires.

[0010] Preferably, the pressure roller is used in conjunction with a roller rod.

[0011] Preferably, the length of the receiving groove is greater than the total length of the positioning rack and the positioning rod.

[0012] Preferably, the length of the rack is greater than the length of the positioning rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the utility model, a servo motor is provided, which drives the lead screw to rotate forward and reverse. The forward and reverse rotation of the lead screw drives the movable block to move up and down under the limiting action of the guide rod and the guide block. The movable block moves up and down, driving the pressure roller on the bottom of the lifting seat to follow the lifting and lowering, thereby realizing an electric way to adjust the pressure between the pressure roller and the roller rod, which is conducive to adjusting the appropriate pressure and avoiding frequent wire breaks. The adjustment is more labor-saving and convenient, and the practicability is strong, and it is worthy of promotion.

[0015] 2. In the utility model, a detachable pressure roller is provided, and the gear is rotated by turning the handle. The rotation of the gear drives the rack engaged with it to translate and be stored in the storage groove. At this time, the spring is compressed and deformed to store energy. The translation of the rack drives the positioning rod to move out of the positioning groove on the surface of the bracket. At this time, the positioning rod no longer fixes the bracket. The pressure roller on the bracket can be removed by pulling the bracket downward, and vice versa, thereby realizing convenient disassembly and assembly of the pressure roller.
