Technical Field

[0001] The utility model belongs to the technical field of non-woven fabric production, and particularly relates to a feeding device for non-woven fabric raw materials. Background Technique

[0002] Non-woven fabric refers to a fabric made of fibers arranged in a directional or random manner through friction, entanglement, adhesion, or a combination of these methods; the production raw materials of non-woven fabric include polypropylene, polyester, polyamide fiber, polyacrylonitrile fiber, and viscose fiber, etc.

[0003] During the production process of non-woven fabric, it is necessary to operate the feeding device for raw materials to perform the feeding operation. The structure of the feeding device for raw materials includes: a material barrel, a barrel cover, a feeding hopper, a support leg, a base plate, a discharge pipe, and a valve, etc. The non-woven fabric raw materials are introduced into the interior of the material barrel through the feeding hopper, and the valve is opened to enable the non-woven fabric inside the material barrel to be discharged through the discharge pipe, so as to achieve the purpose of feeding non-woven fabric raw materials.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. For the existing feeding device for non-woven fabric raw materials, during the use process, due to the changes in factors such as the viscosity and fluidity of the raw materials, the pressure difference during the feeding process is prone to fluctuate, which is not convenient for ensuring the stable flow and uniform distribution of the raw materials, and will reduce the output and quality of non-woven fabric.

[0006] 2. For the existing feeding device for non-woven fabric raw materials, during the assembly process, especially when connecting adjacent pipes, flange plates are connected to the ends of two adjacent pipes, and bolts are rotated to lock and connect the two flange plates to complete the connection between two adjacent pipes. However, due to the large number of bolts, the operation steps will be increased, and the workload of the staff will be increased.

[0007] Therefore, we provide a feeding device for non-woven fabric raw materials to solve the above problems. Content of the Utility Model

[0008] The purpose of the utility model is to provide a feeding device for non-woven fabric raw materials, which solves the problems that the existing feeding device for non-woven fabric raw materials is not convenient to adjust the pressure difference according to the actual situation and has a large assembly workload by setting a pressure difference detection component and a locking component.

A lower communicating pipe is communicated with the lower end of a fixed cylinder arranged at the lower end of the movable cylinder. An electromagnetic valve is connected to the peripheral side wall of the lower communicating pipe. An upper placement groove formed in the fixed cylinder sleeves the movable cylinder. A wire hole is formed in the lower surface of the fixed cylinder. A pressure sensor is connected to the inner bottom of the upper placement groove. A spring connected to the pressure sensor has an upper end connected to a contact rod. The upper end of the contact rod is connected to the inner top of a lower placement groove formed in the lower end of the movable cylinder. A locking component is arranged at the lower end of the lower communicating pipe. A discharge pipe is communicated with the lower end of a movable sleeve in the locking component.

A screw rod is rotatably connected to the interior of a bearing connected to the annular seat by interference fit. A screw barrel threadedly connected to the peripheral side of the screw rod has an upper end connected to the lower surface of the material barrel.

[0011] The utility model is further arranged such that an electrical connection is established between the output end of the pressure sensor and the input end of the controller, and an electrical connection is established between the output end of the controller and the input end of the electromagnetic valve.

[0012] The utility model is further arranged such that a guide rod is connected to the inner bottom of the upper placement groove, and a spring sleeved on the peripheral side wall of the guide rod has an upper end connected to the lower surface of the movable cylinder.

[0013] The utility model is further arranged such that a sleeve is sleeved on the peripheral side wall of a movable rod connected to the annular seat, and the upper end of the sleeve is connected to the lower surface of the material barrel.

[0014] The utility model is further arranged such that bolts are threadedly connected to a base plate arranged below the material barrel, and hydraulic rods connected to the lower ends of hydraulic cylinders symmetrically connected to the lower surface of the material barrel are connected to the base plate at their lower ends.
