Description

Technical Field

[0001] The utility model relates to an auxiliary device for producing polytetrafluoroethylene suspension resin, in particular to a polytetrafluoroethylene suspension resin feeding device. Background Art

[0002] During the production process of polytetrafluoroethylene suspension resin, the suspension resin powder needs to be fed into the production equipment from the feeding port of the equipment. Since the production equipment is very high and its feeding port is located at the top of the production equipment, the prior art usually involves manually standing at a height to carry the polytetrafluoroethylene suspension resin to the feeding location and then feeding it into the feeding port. This prior feeding method, on the one hand, requires workers to frequently feed materials (feeding once every 0.5 hours, 16 times per shift, and high-lifting operations are required) due to the continuous operation of the production equipment. This results in high labor intensity, high labor costs, and certain risks. At the same time, one worker can usually operate at most one production equipment, resulting in low production efficiency. On the other hand, manual observation of the material status is often required during the production process, and it is often difficult to observe in time during the busy work of the workers. As a result, the equipment may run idle due to the workers' negligence, resulting in production losses. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a polytetrafluoroethylene suspension resin feeding device which can effectively reduce labor intensity, improve production efficiency and reduce production cost.

[0004] In order to solve the above technical problems, the utility model discloses a polytetrafluoroethylene suspension resin feeding device, comprising a feeding box, a spiral conveying device connected between the feeding box and the feeding port of the production equipment, and a controller serving as a control unit. A stirring device for stirring the material in the feeding box is provided at the bottom of the feeding box, and a suction fan for sucking the powdered material into the spiral conveying device is provided between the feeding box and the spiral conveying device. The control part of the stirring device and the control part of the suction fan are both connected to the controller. A sensor connected to the controller is also installed at the feeding port. The feeding information sensed by the sensor can be transmitted to the controller, and the controller controls the working state of the stirring device and the suction fan according to the sensed feeding information.

[0005] An air pipe for air injection is also introduced into the feeding box.

[0006] The air pipe is provided with an air source by a pneumatic device, and the controller is connected to a control part of the pneumatic device and can spray air into the feeding box through the air pipe.

[0007] The air pipe is arranged with air injection holes located in the feeding box.

[0008] The stirring device comprises a stirring motor, a stirring connecting rod connected to the stirring motor, and a stirring blade installed on the stirring connecting rod and located in the feeding box.

[0009] The spiral conveying device comprises a conveying pipeline, a spiral blade arranged in the conveying pipeline, and a conveying motor for driving the spiral blade to rotate.

[0010] The height of the feeding box is lower than the height of the production equipment.

[0011] The conveying pipeline is obliquely arranged between one side of the bottom of the feeding box and the top of the feeding port.

[0012] The advantages of the utility model are:

[0013] The feeding information sensed by the sensor is transmitted to the controller, and then the controller controls the specific working states of the stirring device and the suction fan according to the sensed feeding information to achieve the purpose of automatic feeding. The raw materials can be fed into the production equipment in time by means of sensing and automatic control by the sensor, which not only reduces the losses caused by equipment idling due to workers' negligence, but also uses a special feeding box to reduce the frequent feeding times of workers, reduces labor intensity and labor costs and improves production efficiency. Furthermore, jetting while the powdered material is being stirred can effectively prevent the powder from arching and causing residue, thereby ensuring the feeding effect. In addition, the suction fan is used to increase the speed at which the powdered material enters the threaded blade tube, which reduces the equipment operation time and consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The utility model is a schematic structural diagram of a polytetrafluoroethylene suspension resin feeding device. Implementation

[0015] The polytetrafluoroethylene suspension resin feeding device of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] As shown in the figure, the polytetrafluoroethylene suspension resin feeding device of the utility model comprises a feeding box 1, a screw conveying device 4 connected between the feeding box 1 and the feeding port 3 of the production equipment 2, and a controller 5 as a control unit. The height of the feeding box 1 is lower than the height of the production equipment 2, which is convenient for workers to feed powdered materials (suspended resin powder) into the feeding box. A stirring device 6 for stirring the materials in the feeding box is provided at the bottom of the feeding box 1. As can be seen from the figure, the stirring device 6 comprises a stirring motor 10, a stirring connecting rod 11 connected to the stirring motor, and a stirring blade 12 installed on the stirring connecting rod and located in the feeding box, and the screw conveying device 4 comprises a conveying device 11, a stirring device 11 connected to the stirring motor, and a stirring blade 12 installed on the stirring connecting rod and located in the feeding box. A conveying pipe 13, a spiral blade 14 arranged in the conveying pipe and a conveying motor 15 for driving the spiral blade to rotate, wherein the conveying pipe 13 is obliquely arranged between the bottom side of the feeding box and the top of the feeding port, and a suction fan 7 for sucking powdered materials into the spiral conveying device is arranged between the feeding box 1 and the spiral conveying device 4, the control part of the stirring device 6 and the control part of the suction fan 7 are both connected to the controller 5, and a sensor 8 connected to the controller is also installed at the feeding port 3, and the feeding information sensed by the sensor 8 can be transmitted to the controller 5 and the controller controls the working state of the stirring device and the suction fan according to the sensed feeding information.

[0017] Furthermore, an air pipe 9 for jetting is introduced into the feeding box 1, and the air pipe 9 is provided with an air source by a pneumatic device. The controller 5 is connected to the control part of the pneumatic device and can jet into the feeding box through the air pipe. The air pipe 9 is provided with jet holes located in the feeding box 1.

[0018] Here’s how it works:

[0019] By tilting the conveying pipe 13 between the bottom side of the feeding box and the top of the feeding port, the feeding port of the production equipment is connected to ensure that the suspended resin powder can smoothly enter the feeding port of the equipment. During operation, through the sensor installed at the feeding port of the production equipment, when the height of the suspended resin powder is lower than the sensor, the sensor feedbacks a signal to the controller, and the controller controls the motor to operate for stirring and jetting an appropriate amount. At the same time, the suction fan sucks the suspended resin powder into the threaded blade pipe, and the suspended resin powder is sent to the feeding port of the production equipment through the spiral blades in the spiral conveying device to complete the feeding. When the height of the suspended resin powder is higher than the sensor, the controller controls all equipment to stop running.

[0020] This polytetrafluoroethylene suspension resin feeding device is made entirely of stainless steel materials to ensure that the raw materials are not contaminated. After using this polytetrafluoroethylene suspension resin feeding device, feeding 3 times per shift can meet the production needs of the shift, greatly improving efficiency and allowing more time to take care of other equipment and things. Through actual application, it can be seen that after using this polytetrafluoroethylene suspension resin feeding device, a worker can operate 6 devices at the same time, and the efficiency is increased by 2 times.
