[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Powder packaging machines are a general term for equipment used to package powder products. They are widely used in metal ores, pharmaceutical and chemical raw materials, dyes, kaolin, plastics, and food processing. They transform traditional manual packaging operations into automatic or semi-automatic filling machines. Phenolic resin powder is a powdered polymer produced by the polycondensation reaction of phenolic compounds and aldehydes. Depending on the synthesis conditions and molecular structure, phenolic resin powders can be divided into thermoplastic and thermosetting types.

[0004] At present, due to the special properties of phenolic resin powder, powder will leak from the connection between the filling port and the filling bag during the filling process. If inhaled into the body, it will cause harm to the operator. Some powder packaging machines will press the bag opening. If the bag opening is large, wrinkles will appear when pressed, and the bag opening cannot be completely fitted with the outer wall of the filling port. It cannot be completely compressed, and a certain amount of powder leakage is inevitable. In addition, different filling bags have different lengths during filling. If the filling bag is short and cannot be placed on the placement board, the operator needs to carry the filling bag by hand for filling. The operation is too frequent, time-consuming and labor-intensive. Utility Model Content

[0038] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0039] At present, due to the special properties of phenolic resin powder, powder will leak from the connection between the filling port and the filling bag during the filling process. If inhaled into the body, it will cause harm to the operator. Some powder packaging machines will press the bag opening. If the bag opening is large, wrinkles will appear when pressed, and the bag opening cannot be completely fitted with the outer wall of the filling port. It cannot be completely compressed, and a certain amount of powder leakage is inevitable. In addition, different filling bags have different lengths during filling. If the filling bag is short and cannot be placed on the placement board, the operator needs to carry the filling bag by hand for filling. The operation is too frequent, time-consuming and labor-intensive.

[0040] The present invention will be described in detail below with reference to the accompanying drawings. The present embodiment discloses a phenolic resin powder packaging device, such as Figure 1 As shown, it includes a filling device 3 and a hopper 2 connected to the filling device 3, and also includes a bag tightening device 1, which is connected to the hopper 2 through a discharge pipe 10;

[0041] During filling, the phenolic resin powder is transported to the hopper 2 through the filling device 3, enters the discharge pipe 10 through the hopper 2, enters the tube body position of the bag opening tightening device 1, and then the bag opening of the filling bag 12 is tightened by the bag opening tightening device 1, thereby preventing the phenolic resin powder from leaking from the gap between the bag opening and the pipe during filling; the placement device 9 is used to place the filling bag 12 and adjust the position of the placement plate 904 according to the size of the filling bag 12, so that the operator does not need to carry the filling bag 12 for filling, thereby improving the filling efficiency.

[0042] like Figure 2 、 Figure 4 as well as Figure 5 As shown, the bag tightening device 1 includes an outer shell 101, a second tube body 112 is provided on the inner side of the outer shell 101, and the second tube body 112 is connected to the outer shell 101; a first tube body 110 is provided at the lower end of the second tube body 112, and an annular groove is provided on the outer surface of the first tube body 110; hydraulic cylinders 102 are provided at both ends of the upper surface of the outer shell 101, and the output end of the hydraulic cylinder 102 passes through the outer shell 101 and is connected to the connecting plate 103.

[0043] A first connecting rod 104 is provided at one end of the lower part of the connecting plate 103, and the lower surface of the first connecting rod 104 is a slope. A moving block 106 is provided at one end of the first connecting rod 104, and a first semicircular ring 107 is provided at one end of the moving block 106; a second connecting rod 108 is provided at the other end of the lower part of the connecting plate 103, and the second connecting rod 108 passes through the upper surface of the first tube body 110 and is connected to the second semicircular ring 109.

[0044] The outer shell 101 is used to protect the internal structure and install the hydraulic cylinder 102 and the mounting plate 105; when in use, the hydraulic cylinder 102 drives the connecting plate 103 to rise and fall, and then the connecting plate 103 drives the first connecting rod 104 and the second connecting rod 108 to rise and fall.

[0045] Because the lower surface of the first connecting rod 104 is an inclined surface, the first connecting rod 104 is in close contact with the moving block 106. As the first connecting rod 104 descends, the moving block 106 is gradually pushed, thereby driving the first semi-circular ring 107 to be pushed into the annular groove of the first tube body 110. The inner surface of the first semi-circular ring 107 is in close contact with the inner wall surface of the annular groove, and the return spring 113 is stretched at the same time; when the first connecting rod 104 rises, the moving block 106 is gradually pulled back under the action of the elastic force of the return spring 113, that is, it moves in the direction away from the annular groove, thereby causing the first semi-circular ring 107 to gradually move out of the annular groove.

[0046] The second connecting rod 108 descends synchronously with the first connecting rod 104. The descent of the second connecting rod 108 drives the second semicircular ring 109 to move downward, thereby causing the lower surface of the second semicircular ring 109 to move toward the upper surface of the first semicircular ring 107; when the second connecting rod 108 rises, the second semicircular ring 109 rises with the second connecting rod 108 until the upper surface of the second semicircular ring 109 is in close contact with the surface of the first tube body 110. At this time, the moving block 106 has also been reset, and the filling bag 12 can be put on again for filling.

[0047] like Figure 6 As shown, the first connecting rod 104 and the second connecting rod 108 are both in a descending state. It can be seen that the lower end of the first connecting rod 104 is an inclined surface. The first connecting rod 104 continues to descend to push the moving block 106, so that the inner surface of the first semicircular ring 107 is in close contact with the inner surface of the annular groove, thereby pressing the side of the bag opening of the filling bag 12; and after the operator puts on the filling bag 12, the upper end of the bag opening exceeds the part of the top surface of the first semicircular ring 107, and the second semicircular ring 109 is driven by the second connecting rod 108 to press this part, thereby ensuring the complete closure of the bag opening, avoiding leakage caused by wrinkles due to the bag opening being too large or leakage caused by loose compression, and realizing double-layer protection. Even if the operator puts the bag opening of the filling bag 12 below the top surface of the first semicircular ring 107, the second semicircular ring 109 can be pressed down to form a closed space to prevent leakage.

[0048] like Figure 7 As shown in the figure, the bag opening of the canned bag has been pressed by the first semicircular ring 107 and the second semicircular ring 109. It can be seen that the inner wall surface of the first semicircular ring 107 presses the bag opening position into the annular groove, and the second semicircular ring 109 presses the bag opening against the first semicircular ring 107, completely pressing the bag opening position, effectively preventing powder leakage.

[0049] like Figure 3 As shown, a mounting plate 105 is provided at the lower end of the moving block 106, one end of which is connected to the inner wall of the outer shell 101. Guide plates 114 are provided on both sides of the moving block 106, and the guide plates 114 are connected to the mounting plate 105. The guide plates 114 provide guidance for the movement of the moving block 106, ensuring that the moving direction of the moving block 106 is accurate.

[0050] A return spring 113 is provided at the upper end of the mounting plate 105. One end of the return spring 113 is connected to the moving block 106, and the other end of the return spring 113 is connected to the inner wall surface of the outer shell 101. The return spring 113 is used to reset the moving block 106. After the moving block 106 is pushed out by the first connecting rod 104, the first connecting rod 104 is retracted, and the return spring 113 pulls the moving block 106 back to its initial position.

[0051] like Figure 4 As shown, the first connecting rod 104 is fixedly connected to the connecting plate 103, and the second connecting rod 108 is fixedly connected to the connecting plate 103. The first tube 110 and the second tube 112 are fixedly connected. The lower end of the first tube 110 is provided with a guide tube 111, which is fixedly connected to the first tube 110.

[0052] When the filling bag 12 needs to be put on, it is difficult to put it on quickly if the position is not aligned. Therefore, a guide tube body 111 is provided. When in use, the filling bag 12 is put on along the guide tube body 111, and the filling bag 12 can be put on quickly, thereby improving the filling efficiency.

[0053] A first support plate 4 is provided at one end of the filling device 3, and a second support plate 5 is provided at one end of the first support plate 4. A control device 6 is provided on the second support plate 5. The control device 6 is electrically connected to the filling device 3, the hydraulic cylinder 102, and the drive motor 901. The control device 6 includes a control box, which is provided with a display screen, buttons, and a controller. The controller can be a PLC controller. The button operation activates the filling device 3 for filling. After the filling bag 12 is placed, the hydraulic cylinder 102 is activated to drive the first connecting rod 104 and the second connecting rod 108, and ultimately the first semicircular ring 107 and the second semicircular ring 109 to tighten the bag opening.

[0054] like Figure 8As shown, a support column 7 is disposed at the lower end of the first support plate 4. The support column 7 defines a cavity within which a placement device 9 is disposed. The placement device 9 includes a drive motor 901, the output end of which is connected to a threaded rod 902, which is sleeved with a lifting block 903. A notch 11 is provided on the support column 7, and one end of the lifting block 903 extends out of the notch 11 on the support column 7; one end of the lifting block 903 is connected to a placement plate 904. A base plate 8 is disposed at the lower end of the support column 7 and is fixedly connected to the support column 7.

[0055] The threaded rod 902 is driven to rotate by the driving motor 901, thereby moving the lifting block 903 up and down, and the placement plate 904 is driven to rise and fall by the lifting block 903, and the position of the placement plate 904 is adjusted according to the size of the filling bag 12, thereby eliminating the need for the operator to carry the filling bag 12 by hand for filling, thereby improving the filling efficiency.

[0056] Guide rods 905 are set at both ends of the threaded rod 902. The guide rods 905 pass through the lifting block 903. The guide rods 905 and the lifting block 903 are movably connected. The guide rods 905 provide guidance for the lifting block to ensure that the lifting block 903 moves in an accurate direction and limit the lifting block 903 to prevent it from rotating with the threaded rod 902.

[0057] like Figure 9 and Figure 10 As shown, it also includes an exhaust device 13, which is arranged at the upper end of the outer shell 101. The exhaust device 13 includes an exhaust pump 1301, the inlet end of the exhaust pump 1301 is connected to the air inlet pipe 1302, and one end of the air inlet pipe 1302 is connected to the discharge pipe 10; the outlet end of the exhaust pump 1301 is connected to the air outlet pipe 1303, and one end of the air outlet pipe 1303 is connected to the air storage box 1304; a plurality of air outlets 1305 are provided on the air storage box 1304.

[0058] After the filling bag 12 is compressed, the air pump 1301 is started, and the gas in the filling bag 12 is pumped into the air inlet pipe 1302, then into the air outlet pipe 1303, and then into the air storage box 1304 through the air outlet pipe 1303, and then discharged through the air outlet 1305 on the air storage box 1304. After the gas in the filling bag 12 is exhausted, the filling can be carried out, thereby ensuring that the powder can smoothly enter the filling bag 12. Specifically, the air pump 1301 is connected to a corresponding power supply, and the air pump 1301 uses the periodic change of the pump chamber volume to complete the suction and exhaust, thereby achieving the purpose of suction.

[0059] How to use the phenolic resin powder packaging device:

[0060] During use, the bag opening of the filling bag 12 is put into the corresponding position along the guide tube body 111, so that the upper end of the bag opening is higher than the height of the top of the first semicircular ring 107. Then, the placement device 9 is controlled by the control system, so that the driving motor 901 drives the threaded rod 902 to rotate, and then the lifting block 903 moves up and down, and the lifting block 903 drives the placement plate 904 to rise and fall, so that the bottom of the filling bag 12 contacts the placement plate 904.

[0061] Then start the hydraulic cylinder 102, so that the hydraulic cylinder 102 drives the first connecting rod 104 and the second connecting rod 108 to descend, and the first connecting rod 104 pushes the moving block 106 so that the first semicircular ring 107 pushes the side of the bag opening into the annular groove, and the second connecting rod 108 drives the second semicircular ring 109 to press the upper end of the bag opening on the top of the first semicircular ring 107, thereby achieving compression; then start the exhaust device 13 to extract the gas in the filling bag 12, and then start the filling device 3 to carry out filling.

[0062] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
