TECHNICAL FIELD

[0001] The utility model relates to the technical field of hessian weaving, in particular to a hessian weaving mechanism. BACKGROUND

[0002] Hessian, a kind of coarse cloth bag woven from jute, red hemp or similar plant fibers, is known for its toughness, durability and good air permeability. It is usually used for packaging and transporting various goods, such as grains, seeds, fertilizers, etc. Due to its low cost and reusability, it has a wide range of applications in agricultural and industrial fields.

[0003] On the hessian weaving production line, the horizontal winding method of jute cloth indeed brings many challenges to impurity cleaning. When jute cloth runs in a horizontal state, although the traditional up-and-down brush cleaning device can sweep away some jute dust, short fibers and dust attached to the surface of jute cloth, due to the effect of gravity and lack of effective closed system, these brushed-off impurities often drift around the equipment, not only polluting the workshop environment, but also possibly re-attaching to the surface of jute cloth, forming secondary pollution. This open cleaning method has obvious limitations: on the one hand, the flying impurities may enter the mechanical transmission part, accelerating equipment wear; on the other hand, the fine fibers suspended in the air may cause potential harm to the respiratory health of operators. SUMMARY

[0004] The utility model aims to provide a hessian weaving mechanism, which can keep jute cloth vertical during winding, facilitate impurity cleaning and collection, and prevent scattered impurities from flying. It solves the problem of horizontal winding of jute cloth, which may cause impurities to enter the mechanical transmission part, accelerating equipment wear, and fine fibers suspended in the air may cause potential harm to the respiratory health of operators.

[0024] Motor one 5 and motor two 22 select alternating current motor; alternating current motor is a kind of device that converts alternating current into mechanical energy, and its core structure includes stator and rotor two major parts. Stator is usually composed of iron core and winding, and iron core is stacked by silicon steel sheet to reduce eddy current loss, and winding is embedded in the slot of iron core according to certain law to generate rotating magnetic field. Rotor is located inside the stator, and rotor structure is different according to different types of motor, such as squirrel cage rotor and winding rotor. Squirrel cage rotor is composed of conductive strip and end ring, and winding rotor contains winding and slip ring.

[0025] The working principle of alternating current motor is based on electromagnetic induction and electromagnetic force. When the stator winding is connected with alternating current, a rotating magnetic field is generated inside the motor. The rotating magnetic field interacts with the induced current in the rotor conductor, and according to the law of electromagnetic force, the rotor will be subjected to a torque and start to rotate. The rotating speed of rotor is always slightly lower than the synchronous speed of rotating magnetic field, and the speed difference is called slip, which is the necessary condition for the normal operation of alternating current motor.

[0026] The inner wall of the through hole 14 is provided with a slot 13 at the front and rear ends, and the outer wall of the rotating roller 8 is fixed with an insertion plate 12 at the front and rear ends, which is inserted into the slot 13;

[0027] A threaded groove 15 is formed on the lower surface of the rotating roller 8, and a threaded column 16 is fixed on the upper surface of the positioning disc 3 and extends into the threaded groove 15 and is threadedly connected.

[0028] The handle 10 facilitates the rotation of the positioning disc 3, making it easy to install and disassemble the positioning disc 3, and also facilitating the installation and disassembly of the winding roller 11.

[0029] In this embodiment, when the sack needs to be woven, after various processing, the sack is woven into a hemp cloth 4, and then the hemp cloth 4 needs to be wound up. The rotating roller 8 is inserted into the through hole 14, the insertion plate 12 is inserted into the slot 13, and then the threaded column 16 is inserted into the threaded groove 15 and is threadedly connected. One side of the hemp cloth 4 is wound around the winding roller 11, the motor 5 is started, and the rotating roller 8 and the winding roller 11 rotate and wind up, so that the hemp cloth 4 can be wound vertically, and the short fibers, hemp dust or environmental dust on the hemp cloth 4 can be easily cleaned and collected.

[0030] Embodiment two:

[0031] A circular hole 24 is formed on the upper surface of the box 6, a motor 22 is fixed on the upper surface of the box 6, the bottom end of the transmission shaft of the motor 22 extends into the circular hole 24, and a rotating rod 25 is fixed at the bottom end of the transmission shaft of the motor 22.

[0032] A through groove 20 is formed on the inner wall of the groove 21 of the box 6, a groove 19 is formed on the upper surface of the box 2, and the outer wall of the dust removal pipe 18 extends into the groove 19 and is fixed. The through groove 20 is vertically aligned with the center of the groove 19.

[0033] The connecting pipe 17 is connected to the dust collection device at the bottom end.

[0034] The dust collection device is a high-efficiency cleaning equipment with delicate structure and powerful function, mainly composed of motor, fan, filter system and dust collection container. The motor as the heart drives the fan to rotate at high speed, generating strong negative pressure airflow. This airflow like invisible suction hand separates dust and debris from the ground or object surface. The fan blade is designed cleverly, which can maximize the suction and speed of the airflow to ensure the cleaning effect.

[0035] The filter system is the guardian of the dusting device, which is composed of multiple layers of filter screens, including the primary filter screen and the high-efficiency particulate air filter, which act like sieves, layer by layer intercepting dust and allergens, capturing them firmly and preventing them from escaping back into the air, ensuring that the discharged air is fresh and clean. The dust collection container or bag plays the role of collector, which is located at the end of the air flow path, used to store the dust and debris sucked in, facilitating user cleaning and replacement.

[0036] The working principle of the dusting device is similar to the cyclone in nature. The motor drives the fan to rotate, generating a high-speed airflow. The airflow speed increases when passing through the narrow channel, forming a low-pressure area, thereby generating strong suction at the suction port. Dust and debris are drawn by this force, entering the device along with the airflow, and are screened layer by layer by the filter system, finally being safely collected in the dust collection container.

[0037] In this embodiment, when the impurities on the linen 4 need to be cleaned, the other side of the linen 4 is threaded between the two box bodies 6, so that the front and rear brushes 26 are attached to the front and rear surfaces of the linen 4, respectively. Start motor 2, make the rotating rod 25 and the brush 26 rotate, the brush 26 can clean the short fibers, lint or environmental dust on the front and rear surfaces of the linen 4, at the same time, the connecting pipe 17 is connected to the dust collection device, the dust collection device can collect the short fibers, lint or environmental dust cleaned, preventing the short fibers, lint or environmental dust cleaned from flying.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.
