Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a screw feeding and conveying device for hot molding granules. Background Art

[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. It can convey horizontally, inclined or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. When the screw shaft rotates, due to the gravity of the material and the friction between the material and the trough wall, the material can only move forward along the bottom of the conveyor trough under the push of the blades, just like a non-rotating nut moving in translation along the rotating screw [3]. The main forward force of the material comes from the force of the spiral blades pushing the material upward and forward along the tangential direction of the blades when rotating axially.

[0003] The prior art has the following deficiencies: when the existing screw conveying device conveys materials, it is affected by the height of the subsequent conveying pipeline, and the inclination angle of the device needs to be adjusted. When the existing conveying device is installed and used, its installation direction is usually fixed, such as horizontal, vertical or inclined. It is impossible to conveniently adjust the inclination angle of the device according to the height of the subsequent conveying pipeline, so that the device cannot stably convey materials to subsequent conveying pipelines of different heights, which will affect the efficiency of material transportation.

[0027] The supporting mechanism 2 is arranged at the bottom of the device body 1 and is used to adjust the inclination angle of the device body 1 so that the device body 1 can feed and transport pipes at different heights.

[0028] In order to facilitate the transportation of materials, Figure 2 and Figure 3 As shown, the device body 1 includes a fixed shell 101, a feed pipe 102 is fixedly installed on the top of one end of the fixed shell 101, a discharge pipe 103 is fixedly installed on the bottom of one end of the fixed shell 101, a sealing plate 104 is provided at one end opening of the fixed shell 101, a rotating shaft 106 is rotatably installed inside the fixed shell 101, a first motor 107 is provided at one end of the rotating shaft 106, a spiral conveying piece 108 is fixedly sleeved on the outer side of the rotating shaft 106, and fixed shafts 109 are fixedly installed on the outer walls of both sides of the end of the fixed shell 101 away from the sealing plate 104, materials can be added to the inside of the fixed shell 101 through the feed pipe 102, and the first motor 107 works so that the rotating shaft 106 and the spiral conveying piece 108 can convey the materials, and then the materials can be conveyed to different pipelines through the discharge pipe 103.

[0029] In order to facilitate the adjustment of the inclination angle of the device body 1 so that it can adapt to pipeline transportation work at different heights, such as Figure 2 and Figure 4 As shown, the support mechanism 2 includes a fixed base plate 201, and fixed frames 202 are fixedly installed on both sides of the top end of the fixed base plate 201. The top inner walls of the two fixed frames 202 are rotatably connected to the outer walls of the two fixed shafts 109 respectively. A movable groove 203 is opened on the top of the fixed base plate 201, and an adjusting screw rod 204 is rotatably installed on the inner wall of one side of the movable groove 203. A second motor 205 is provided at one end of the adjusting screw rod 204. A movable seat 206 is threadedly sleeved on the outer side of the adjusting screw rod 204. Both sides of the top of the movable seat 206 are rotatably installed. A traction plate 207 is installed, and a support seat 208 is rotatably installed on the top of one end of the traction plate 207 away from the movable seat 206. The top of the support seat 208 is fixedly connected to the bottom outer wall of one end of the fixed shell 101. The second motor 205 works to rotate the adjusting screw rod 204, so that the movable seat 206 can move along the inner wall of the movable groove 203, and then under the traction of the traction plate 207, the inclination angle of the fixed shell 101 can be adjusted, so that the device body 1 can feed and transport pipes of different heights.

[0030] In order to facilitate the installation and replacement of the rotating shaft 106 and the spiral conveying sheet 108, as shown in FIG. Figure 2 and Figure 3 As shown, the device body 1 includes connecting bolts 105, and multiple connecting bolts 105 are inserted into the outer inner wall of the sealing plate 104 in the form of equidistant annular threads. The end of the connecting bolt 105 away from the sealing plate 104 is threadedly connected to the outer inner wall of one end of the fixed shell 101. The connecting bolts 105 penetrate the sealing plate 104 and are connected to the fixed shell 101, so that the staff can easily install and disassemble the device body 1.

[0031] In order to provide power for the rotation of the spiral conveyor sheet 108, as Figure 2 and Figure 3 As shown, the outer wall of one end of the fixed shell 101 is fixedly connected to the first motor 107, and the first motor 107 is connected to the rotating shaft 106 through the output shaft transmission. The fixed shell 101 can install and fix the first motor 107. When the first motor 107 works, the rotating shaft 106 and the spiral conveying piece 108 rotate, thereby transporting the material entering the fixed shell 101.

[0032] In order to keep the movable seat 206 stable during the movement, Figure 2 and Figure 4 As shown, the support mechanism 2 includes a limiting rod 210, which is fixedly installed on a side of the inner wall of the movable groove 203 away from the adjusting screw rod 204, and the outer side of the limiting rod 210 is movably connected to the inner wall of one side of the movable seat 206. The limiting rod 210 and the movable groove 203 can limit the movement of the movable seat 206, so that the movable seat 206 remains stable during the movement, and then the traction plate 207 can stably adjust the inclination angle of the device body 1.

[0033] In order to keep the device body 1 stable in a horizontal state, Figure 2 and Figure 4 As shown, the support mechanism 2 includes a support rod 209, which is fixedly mounted on the bottom of a support seat 208. The bottom of the support rod 209 is movably connected to the top of one end of the fixed base plate 201. The support rod 209 and the support seat 208 provide support and cushioning, so that the device body 1 can remain stable when adjusted to a horizontal state.

[0034] In order to provide power for the adjustment of the device body 1, as Figure 2 and Figure 4As shown, the outer wall of one end of the fixed base plate 201 is fixedly connected to the second motor 205, and the second motor 205 is connected to the adjusting screw rod 204 through an output shaft transmission connection. The fixed base plate 201 can install and fix the second motor 205. The operation of the second motor 205 causes the adjusting screw rod 204 to rotate, and then the inclination angle of the fixed shell 101 can be adjusted through the movable seat 206 and the traction plate 207.

[0035] The specific implementation method is as follows: when the device is installed and used, according to the different heights of the conveying pipeline, in order to make the device adapt to the conveying pipeline well, the second motor 205 is operated to rotate the adjusting screw rod 204, and the threaded connection between the outer wall of the adjusting screw rod 204 and the inner wall of the movable seat 206 is used to make the movable seat 206 move along the outer wall of the limiting rod 210 and the inner wall of the movable groove 203 on the outside of the adjusting screw rod 204. The limiting rod 210 and the movable groove 203 can limit the movement of the movable seat 206, so that the movable seat 206 remains stable during the movement. Through the traction and pushing action of the two traction plates 207, the support seat 208 can move upward, and then the fixed shell 101 can be pushed to rotate through the connection between the fixed shaft 109 and the fixed frame 202, so that the inclination of the fixed shell 101 can be adjusted. The bevel angle can be adjusted so that the discharge pipe 103 of the device body 1 can adapt to conveying pipelines of different heights, and then materials can be added to the fixed shell 101 through the feed pipe 102, and the rotating shaft 106 is rotated by the operation of the first motor 107, so that the spiral conveying piece 108 can convey the material during the rotation, so that the material can be conveyed to the inlet end of the discharge pipe 103 as the spiral conveying piece 108 rotates, and then the material can be conveyed to the subsequent pipeline through the discharge pipe 103, so that the device body 1 can adapt to subsequent conveying pipelines of different heights, which can improve the adaptability of the device. This embodiment specifically solves the problem that the screw feeding and conveying device in the prior art cannot adapt to the installation work of conveying pipelines of different heights during installation and use, making it impossible for the device to conveniently feed and convey subsequent pipelines of different heights.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
