DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The embodiment of the present application solves the problem that the auger connecting seat is prone to wear and tear during use, which causes local temperature rise, by providing a connecting seat suitable for the product line conveying auger, thereby improving product quality and work capacity.

[0037] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0038] By setting up external connecting pipes and diverter channels, the inner chamber of the base is ventilated by using the external connecting pipes. The auger connecting seat is prone to wear during use, causing local temperature rise. Excessive heat directly affects product quality and work capacity. In addition, on the basis of the external connecting pipes and diverter channels, combined with an air ring, the air source passes through the air holes on the air ring to achieve air source cooling of the bearings at the core part of the inner chamber of the base. A trace amount of air source is introduced from the outside of the base, flows through the inner chamber through the diverter channel of the base, and cools the inside of the chamber and the bearing, effectively and reliably reducing the local working temperature and avoiding product plasticization.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1-Figure 3 As shown, a connecting seat suitable for a product line conveying auger comprises a base 10, a connecting shaft 11 and a bearing 111;

[0041] The bearing 111 is embedded in the base 10, and the connecting shaft 11 is rotatably connected to the base 10 through the bearing 111;

[0042] Sealing frames 115 are provided on both sides of the base 10;

[0043] An inner chamber is formed between the connecting shaft 11 and the two sealing frames 115 and the base 10;

[0044] The base 10 is provided with a flow diversion channel 103 which is in communication with the inner chamber. An external pipe 104 is provided in the flow diversion channel 103, and the external pipe 104 is in communication with the flow diversion channel 103.

[0045] An air ring 112 is disposed inside the base 10 , and the flow diversion channel 103 is connected to the air ring 112 . A plurality of air holes are circumferentially formed on one side of the air ring 112 close to the bearing 111 .

[0046] It should be noted that after the external pipe 104 is installed with the base 10 through the diversion channel 103 , the sealing between the external pipe 104 and the base 10 is good, and the sealing frames 115 on both sides of the base 10 can achieve sealing between the connecting shaft 11 and the base 10 .

[0047] The external pipe 104 delivers a 0.2Mpa micro-pressure gas source to flow through the shunt channel 103 provided on the base 10. The gas source enters the left side of the inner chamber of the base 10, the radial outer ring of the bearing and the right side of the inner chamber through the shunt channel 103. After the gas source enters the right gas ring 112, it enters the core part of the inner chamber through the vent hole on the gas ring 112, completing the entire gas delivery path.

[0048] At the same time, a certain air pressure is applied to the sealing frames 115 on both sides to provide an additional auxiliary sealing effect.

[0049] By providing an external connecting pipe 104 and a bypass channel 103, the internal chamber of the base 10 is ventilated by using the external connecting pipe 104. The auger connecting seat is prone to wear during use, causing local heating. Excessive heat directly affects product quality and work capacity. In addition, on the basis of the external connecting pipe 104 and the bypass channel 103, combined with the air ring 112, the air source passes through the air holes on the air ring 112 to achieve air source cooling of the bearing 111 at the core part of the internal chamber of the base 10. A trace amount of air source is introduced from the outside of the base 10, flows through the internal chamber through the bypass channel 103 of the base 10, and cools the inside of the chamber and the bearing 111, thereby effectively and reliably reducing the local working temperature and avoiding product plasticization.

[0050] like Figure 1 As shown, a limiting hole 102 is provided on the base 10. Through the setting of the limiting hole 102, corresponding bolts are passed through the limiting hole 102 to achieve the connection and fixation between the base 10 and the equipment conveying trough.

[0051] like Figure 1-Figure 3 As shown, a threaded connection hole 101 is provided on the base 10 , the flow diversion channel 103 is located above the threaded connection hole 101 , and the external pipe 104 is threadedly connected to the base 10 through the threaded connection hole 101 .

[0052] By setting a threaded connection hole 101 on the base 10, the threaded connection hole 101 is used to realize the installation between the external pipe 104 and the base 10, thereby improving the stability of the external pipe 104 when inputting the gas source, and facilitating the gas source to realize the cooling of the connection seat.

[0053] like Figure 2 , Figure 5-Figure 7 As shown, two flange members 12 are installed on the base 10, and the two flange members 12 are respectively sleeved on the two ends of the connecting shaft 11 located on the outside of the base 10, and limiting grooves 1231 are provided on both sides of the connecting shaft 11. A through groove 1212 corresponding to the limiting groove 1231 is provided on the flange member 12, and the countersunk bolt 123 passes through the corresponding limiting groove 1231 and the through groove 1212 to be fixed to the connecting shaft 11.

[0054] The flange 12 is provided with a mounting groove 1211 , a backing plate 122 matching the mounting groove 1211 is provided inside the mounting groove 1211 , and the countersunk bolt 123 passes through the mounting groove 1211 and is fixed to the connecting shaft 11 .

[0055] By arranging a backing plate 122 inside the installation groove 1211 , the backing plate 122 is utilized to improve the stability of the installation of the countersunk bolt 123 and the connecting shaft 11 .

[0056] like Figure 1 As shown, at least two flange positioning holes 121 are formed on the flange member 12, and the flange positioning holes 121 are consistent with the flange holes of the auger shaft.

[0057] By providing the flange positioning hole 121 and making the flange positioning hole 121 consistent with the flange hole of the auger shaft, the flange member 12 can be conveniently fastened to the flange on the auger shaft, thereby realizing the connection between adjacent auger shafts.

[0058] like Figure 2-Figure 4 As shown, a slot 113 is provided inside the base 10, and the slot 113 is located at one end of the base 10, and the slot 113 is located between the adjacent sealing frame 115 and the flange 12. A retaining spring 114 is installed inside the base 10, and the retaining spring 114 is clamped with the base 10 through the slot 113, and the connecting shaft 11 is prevented from retreating by the retaining spring 114.

[0059] Furthermore, at least two mounting holes 1141 are provided on the retaining spring 114, and fixing holes corresponding to the mounting holes 1141 are provided on the base 10. When in use, fixing bolts are used to achieve stability between the retaining spring 114 and the base 10, thereby improving the retaining spring 114's anti-retraction effect.

[0060] When in use, the connecting shaft 11 together with the bearing 111 sleeved on the connecting shaft 11 is installed in the base 10, and the bearing 111 is used to realize the rotation between the connecting shaft 11 and the base 10. Then, the flange 12 is sleeved on both ends of the connecting shaft 11 located outside the base 10, and the countersunk bolts 123 are passed through the corresponding through grooves 1212 and the limiting grooves 1231 on the connecting shaft 11 to realize the fixation between the flange 12 and the connecting shaft 11;

[0061] Then, install the base 10 on the equipment conveying trough, use the corresponding bolts to pass through the limiting holes 102 to connect and fix the base 10 to the equipment conveying trough, and fasten the flanges 12 on both sides to the flanges on the adjacent auger shafts respectively to achieve the connection of adjacent auger shafts. In summary, the overall structure completes the design purpose of connection, rotation, sealing and cooling between the auger short shafts.

[0062] Compared with the sleeve-type connection seat in the traditional process, the utility model directly designs the rotor part to be a bearing 111 rotation form that can bear a certain radial load, has a small friction coefficient and a higher transmission efficiency. The connection principle between the auger short shafts is to fix the flanges 12 on both sides to the connecting shaft 11 and then tighten them with the auger flange at 90 degrees to each other, effectively ensuring the overall dynamic balance to achieve the design purpose of the auger transmission connection;

[0063] The utility model has the advantages of low production cost, simple structure, low requirements for operating and maintenance personnel, and easy installation. According to statistical records, this unit has been modified and used since January 2021. The average service life is about one and a half years, and the failure rate is much lower than the three-month service life of the traditional sleeve-type connecting seat, and maintenance only requires replacement of damaged parts, which eliminates and innovates the maintenance method of overall replacement of the sleeve-type damage, effectively reducing the company's production costs. In addition, the utility model can be applied to all packaging auger equipment with similar segmented short-shaft connection conditions.

[0064] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0065] 1. By setting an external pipe 104 and a shunt channel 103, the internal chamber of the base 10 is ventilated by using the external pipe 104. The auger connection seat is prone to wear during use, causing local temperature rise. Excessive heat directly affects product quality and work capacity. On the basis of the external pipe 104 and the shunt channel 103, combined with the air ring 112, the air source passes through the vent holes on the air ring 112 to achieve air source cooling of the bearing 111 at the core part of the internal chamber of the base 10. A trace amount of air source is introduced from the outside of the base 10, flows through the internal chamber through the shunt channel 103 of the base 10, and cools the inside of the chamber and the bearing 111, thereby effectively and reliably reducing the local working temperature and avoiding product plasticization.

[0066] 2. By setting a threaded connection hole 101 on the base 10, the threaded connection hole 101 is used to realize the installation between the external pipe 104 and the base 10, thereby improving the stability of the external pipe 104 when inputting the gas source, and facilitating the gas source to realize the cooling of the connection seat.

[0067] 3. Compared with the sleeve-type connection seat in traditional technology, the utility model directly designs the rotor part to be able to bear a certain radial load, with a small friction coefficient and a higher transmission efficiency. The connection principle between the auger short shafts is to fix the flanges 12 on both sides on the connecting shaft 11 and then tightly connect them with the auger flange at 90 degrees to each other, effectively ensuring the overall dynamic balance to achieve the design purpose of the auger transmission connection.
