Description

Technical Field

[0001] The utility model relates to the technical field of polyester cloth winding, in particular to a pressing device for polyester cloth rolls. Background Technique

[0002] The production process of polyester includes two parts: polycondensation and melt spinning. The raw materials are mainly obtained from petroleum cracking, and can also be obtained from coal and natural gas. At the same time, polyester can be woven into cloth. After weaving, the polyester cloth needs to be wound. When the pressing device for polyester cloth rolls is in use, the polyester cloth is relatively fluffy. After most of the polyester cloth is wound, the polyester cloth is prone to expand after winding, resulting in a large storage area occupied when storing the polyester cloth.

[0003] To improve the above-mentioned disadvantages, the patent with the application number 202321869910.4 in the public technology can be applied, including a connection structure and a clamping structure; a control mechanism and a driving structure are movably connected to the connection structure, and the driving structure is also movably connected to the rotating mechanism at the same time; the clamping structure is fixedly connected to the connection structure. Although when winding the polyester cloth, the overlapping plate 501 can be controlled to automatically slide towards one end through the elastic member 504, and the wound polyester cloth can be extruded through the overlapping plate 501, which can effectively bundle the polyester cloth and perform the pressing operation on the polyester cloth roll.

[0004] However, there are certain disadvantages in the actual use of the clamping structure for pressing the polyester cloth roll. For example: 1. The pressing force between the pressing plate for extruding the polyester cloth and the polyester cloth will increase with the increase of the outer diameter of the polyester cloth roll, which will lead to the situation of loose inside and tight outside of the polyester cloth roll, and it is easy to cause extrusion wrinkles in the polyester cloth deep in the polyester cloth roll, which is not conducive to the high-quality forming of the polyester cloth roll; 2. In addition, during the winding of the polyester cloth, friction will occur between the polyester cloth and the surface of the pressing plate. During this process, static electricity may be generated on the surface of the polyester cloth, and the probability of adsorbing dust particles is relatively high, and the practical performance needs to be strengthened. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressing device for polyester cloth rolls to solve the problem that the pressing force between the pressing plate for extruding the polyester cloth and the polyester cloth increases with the increase of the outer diameter of the polyester cloth roll, which will lead to the situation of loose inside and tight outside of the polyester cloth roll, and it is easy to cause extrusion wrinkles in the polyester cloth deep in the polyester cloth roll, which is not conducive to the high-quality forming of the polyester cloth roll as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A pressing device for a polyester cloth roll, comprising a winding roller, with a polyester cloth wound around the outer side of the winding roller, a pressing plate is pressed against the upper side of the polyester cloth, multiple connecting rods are arranged above the pressing plate, and the connecting rods are connected to the pressing plate through a force application assembly. The force application assembly includes a vertical rod, a vertical cylinder, a first compression spring, a gasket, a cavity bladder, compressed air, a horizontal pipe, a pressure gauge, a safety valve, a bent pipe, a solenoid valve, and a supply pipe. Multiple vertical rods are evenly fixedly connected to the upper surface of the pressing plate. The upper outer wall of the vertical rod is sleeved with a vertical cylinder. A first compression spring is arranged above the vertical rod. Gaskets are fixedly connected to both the upper and lower ends of the first compression spring. The lower gasket is fixedly connected to the top end of the vertical rod. The upper surface of the upper gasket is pressed against the cavity bladder. Compressed air is arranged inside the cavity bladder. Horizontal pipes are fixedly connected to both top ends on both sides of the cavity bladder. The horizontal pipes are fixedly connected to the contact surface of the vertical cylinder. A pressure gauge is fixedly connected to the outer end of one side of the horizontal pipe, and a safety valve is fixedly connected to the outer end of the other side of the horizontal pipe. A bent pipe is fixedly connected to the front top end of the vertical cylinder. The bent pipe penetrates the vertical cylinder and is fixedly connected to the cavity bladder. The bottom end of the bent pipe is fixedly connected to a solenoid valve, and a supply pipe is arranged at the bottom end of the solenoid valve.

[0007] Preferably, sliders are fixedly connected to both the front and rear surfaces of the gasket, and the sliders are slidably clamped to the vertical cylinder through sliding grooves.

[0008] Preferably, a clamp is fixedly connected to the front side of the outer wall of the vertical cylinder.

[0009] Preferably, an auxiliary assembly is arranged on the front side of the outer wall of the vertical rod. The auxiliary assembly includes a through groove, a vertical cylinder, a pin rod, a vertical rod, a clamping block, a dry battery, and a second compression spring. The through groove is opened on the front side of the outer wall of the vertical rod. A vertical cylinder is arranged inside the through groove. A pin rod is inserted into one side of the bottom end of the outer wall of the vertical cylinder. The pin rod penetrates the vertical cylinder, and the end of the pin rod is fixedly connected to the contact surface of the vertical rod. A vertical rod is inserted into the top end inside the vertical cylinder. A clamping block is fixedly connected to the top end of the vertical rod. A dry battery is clamped inside the clamping block, and the dry battery is pressed against the contact surface of the vertical rod. A second compression spring is fixedly connected to the bottom end of the vertical rod, and the bottom end of the second compression spring is fixedly connected to the contact surface of the vertical cylinder.

[0010] Preferably, a square rod is vertically arranged inside the vertical rod, and the bottom end of the square rod is fixedly connected to the contact surface of the vertical cylinder.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: This pressing device for a polyester cloth roll has the following advantages compared with the traditional technology:

[0012] Through the cooperation among the winding roller, the polyester cloth, the pressing plate, the connecting rod and the force-applying assembly, during the winding operation of the polyester cloth by the rotation of the winding roller, the lower surface of the pressing plate will press the polyester cloth, so that the polyester cloth can be tightly wound around the outer side of the winding roller. As the outer diameter of the polyester cloth roll above the outer wall of the winding roller increases, the internal pressure of the cavity capsule increases. After the internal air pressure of the cavity capsule increases, the internal compressed air 506 will be discharged through the safety valve, that is, the volume of the cavity capsule will decrease as the polyester cloth roll outside the winding roller increases. The force exerted by the cavity capsule on the gasket, the first compression spring and the top of the vertical rod can be kept constant, and further, the pressure intensity exerted by the lower surface of the pressing plate on the polyester cloth can be kept constant. In this way, the situation of loose inside and tight outside will not occur during the formation of the polyester cloth roll, and then the polyester cloth deep in the polyester cloth roll will not be squeezed and wrinkled, which is convenient for the high-quality formation of the polyester cloth roll.

[0013] Through the cooperation among the winding roller, the polyester cloth, the pressing plate, the connecting rod, the force-applying assembly and the auxiliary assembly, the operator can clamp the dry battery inside the clamping block, and then apply a downward force to the vertical rod to cause the second compression spring to undergo compressive deformation. While keeping the force applied to the vertical rod, the vertical rod is erected inside the normal. After releasing the force on the vertical rod, the second compression spring rebounds, and the dry battery at the top of the clamping block will be in close contact with the contact surface of the vertical rod. In this way, the static electricity generated by the friction between the pressing plate and the polyester cloth will be absorbed by the dry battery through the conduction of the pressing plate and the vertical rod, achieving the effect of eliminating static electricity, so as to avoid the situation that the polyester cloth adsorbs dust particles due to the generation of static electricity, and the practical performance is enhanced.

A pressure gauge 508 is fixedly connected to the outer end of one side of the horizontal pipe 507. A safety valve 509 is fixedly connected to the outer end of the other side of the horizontal pipe 507. The safety valve 509 is a special valve in which the closing member is in a normally closed state under the action of an external force.

[0023] An auxiliary component 6 is provided on the front side of the outer wall of the vertical rod 501. The auxiliary component 6 includes a through groove 601, a vertical cylinder 602, a pin rod 603, a vertical rod 604, a clamping block 605, a dry battery 606, and a second compression spring 607. The through groove 601 is opened on the front side of the outer wall of the vertical rod 501. A vertical cylinder 602 is provided inside the through groove 601. One side of the bottom end of the outer wall of the vertical cylinder 602 is inserted with a pin rod 603.

The top end of the vertical rod 604 is fixedly connected with a clamping block 605. A dry battery 606 is clamped inside the clamping block 605. The dry battery 606 is a button-type dry battery. Its principle of adsorbing and eliminating static electricity is as follows: Static electricity is a natural phenomenon and can be generated in many ways, such as contact, friction, flow, etc. The basic process of its generation can be summarized as: contact → charge → transfer → formation of an electric double layer → charge separation. The best way to eliminate static electricity is to find a third party to transfer the charge. The principle of using a battery to adsorb static electricity is equivalent to the electrolytic cell principle from a chemical perspective, transferring the static charge to the battery conductor, so as to achieve the purpose of eliminating static electricity. The dry battery 606 abuts against the contact surface of the vertical rod 501. The bottom end of the vertical rod 604 is fixedly connected with a second compression spring 607. The coefficient of the second compression spring 607 is 1 - 3 N / cm. The bottom end of the second compression spring 607 is fixedly connected to the contact surface of the vertical cylinder 602. A square rod 10 is vertically provided inside the vertical rod 604. The outer wall of the square rod 10 is in clearance fit with the inner wall of the vertical rod 604. The bottom end of the square rod 10 is fixedly connected to the contact surface of the vertical cylinder 602, which can improve the stability of the vertical rod 604 when sliding up and down.

[0024] During the use of the pressing device for the polyester cloth roll, during the operation, the operator first fixedly connects the connecting rod 4 to a suitable position outside, so that the pressing plate 3 is located above the winding roller 1. During the winding operation of the polyester cloth 2 by the winding roller 1, the lower surface of the pressing plate 3 presses the polyester cloth 2. During this process, the static electricity generated by the friction between the pressing plate 3 and the polyester cloth 2 will be absorbed by the dry battery 606 through the conduction of the pressing plate 3 and the vertical rod 501 to achieve the effect of eliminating static electricity, so as to avoid the situation that the polyester cloth 2 adsorbs dust particles due to the generation of static electricity. The polyester cloth 2 is tightly wound around the outside of the winding roller 1. During this process, as the outer diameter of the polyester cloth roll above the outer wall of the winding roller 1 cannot increase, the reaction force received by the lower surface of the pressing plate 3 from the formed polyester cloth 2 will also increase accordingly. Through the transmission of the vertical rod 501, the first compression spring 503 and the gasket 504, the pressure intensity received by the cavity bladder 505 increases, and the internal pressure of the cavity bladder 505 increases accordingly. After the internal air pressure of the cavity bladder 505 increases to the maximum critical point of the safety valve 509, the internal air pressure of the cavity bladder 505 will be discharged through the safety valve 509, that is, the volume of the cavity bladder 505 will shrink as the polyester cloth roll outside the winding roller 1 increases, so that the acting force of the cavity bladder 505 on the gasket 504, the first compression spring 503 and the top of the vertical rod 501 can be kept constant, and further the pressure intensity applied by the lower surface of the pressing plate 3 to the polyester cloth 2 can be kept constant, so that the situation of loose inside and tight outside will not occur during the formation of the polyester cloth roll, and then the situation of extrusion wrinkles of the polyester cloth 2 deep in the polyester cloth roll can be avoided, which is convenient for the high-quality formation of the polyester cloth roll.
