[0043] refer to Figure 1-Figure 12 One embodiment of the utility model provides an automatic tobacco feeding device, comprising:

[0044] The tobacco conveying device 100 includes a conveyor belt mechanism 110, a conveying detection component 120, a position detection component 170 and a roller conveying component 130. The conveyor belt mechanism 110 is provided with enclosures 140 on both sides along the conveying direction. The conveying detection component 120 includes a first material level detection unit 121 and a first feed detection unit 122. The first material level detection unit 121 is installed on the conveyor belt mechanism 110 and is close to the feed end of the conveyor belt mechanism 110. The roller conveying component 130 is installed on the conveyor belt mechanism 110. The first feed detection unit 122 is installed on the conveyor belt mechanism 110 and is arranged on the feed side of the roller conveying component 130. The position detection component 170 includes a first proximity switch 171, a second proximity switch 172, and a third proximity switch 173. The first proximity switch 171, the second proximity switch 172, and the third proximity switch 173 are evenly installed before the conveying roller 131 and below the inner surface of the enclosure 140. In the corresponding working circuit diagram, it also includes a material level detection terminal A, a material feed detection terminal B, a position detection terminal C, a position detection terminal D, a position detection terminal E, an enable terminal F of the first frequency converter 401, an enable terminal G of the second frequency converter 402, an enable terminal H of the third frequency converter 403, and a speed terminal I of the third frequency converter 403.

[0045] A tobacco feeding device 200, which is arranged at the discharge end of the conveyor belt mechanism 110;

[0046] A tobacco feeding device 300, which is arranged at the discharge end of the tobacco feeding device 200;

[0047] The control module is electrically connected to the tobacco loading device 200, the tobacco feeding device 300, the conveyor belt mechanism 110, the first material level detection unit 121, the first feed detection unit 122, the first proximity switch 171, the second proximity switch 172, the third proximity switch 173 and the roller conveying assembly 130. When the first material level detection unit 121 obtains that the tobacco stored on the conveyor belt mechanism 110 reaches a first preset value, the control module controls the upstream device to stop feeding to the conveyor belt mechanism 110 through the first frequency converter 401. When the first feed detection unit 122 obtains that the tobacco on the feeding side of the roller conveying assembly 130 is less than a second preset value, the control module controls the conveyor belt mechanism 110 to start feeding through the second frequency converter 402. When the tobacco reaches the first proximity switch 171, the second proximity switch 172 and the third proximity switch 173, the control module changes the speed of the conveying roller 131 through the third frequency converter 403.

[0048] Based on the above structure, the automatic tobacco feeding device in this embodiment can, on the one hand, sequentially receive tobacco from the upstream equipment through the tobacco conveying device 100, the tobacco loading device 200 and the tobacco feeding device 300, and orderly deliver the tobacco to the downstream processing equipment;

[0049] In the second aspect, the tobacco conveying device 100 is provided with a conveyor belt mechanism 110, a conveying detection component 120 and a roller conveying component 130, and the automatic tobacco feeding device further includes a control module, and the conveying detection component 120 further includes a first feeding detection unit 122 and a first material level detection unit 121, and the first feeding detection unit 122 is used to obtain whether the tobacco on the feeding side of the roller conveying component 130 is less than a second preset value. Fig.12 In the steps S101, S102, and S105 shown, when the first feed detection unit 122 obtains that the tobacco on the feed side of the roller conveying assembly 130 is less than the second preset value, the control module controls the conveyor belt mechanism 110 to start feeding through the second inverter 402 to avoid material shortage in subsequent processing. In addition, as in steps S103 and S104, a first material level detection unit 121 is set. When the tobacco storage amount at the feed end of the conveyor belt mechanism 110 reaches the first preset value, the first material level detection unit 121 can feed back information to the control module, and the control module controls the upstream equipment to stop feeding through the first inverter 401, thereby avoiding excessive tobacco accumulation in the storage cavity formed by the conveyor belt mechanism 110 and the enclosure 140 and overflowing, thereby realizing the automatic feeding of tobacco in the conveyor belt device and full-load shutdown;

[0050] Thirdly, a roller conveying assembly 130 is provided, and by cooperating with the conveyor belt mechanism 110, when the roller conveying assembly 130 rotates, the tobacco placed on the conveyor belt mechanism 110 can be gradually pushed toward the downstream direction, thereby realizing orderly feeding.

[0051] refer to Figure 3-Figure 5 Furthermore, the roller feeding assembly 130 in this embodiment includes a conveying roller 131 and a roller feeding motor 132. Both ends of the conveying roller 131 are rotatably installed on the enclosure 140, and the axial direction of the conveying roller 131 is perpendicular to the conveying direction of the conveyor belt mechanism 110. The roller feeding motor 132 is transmission-connected to the conveying roller 131. The control module is electrically connected to the roller feeding motor 132 through the third frequency converter 403. During the feeding process of the conveyor belt mechanism 110, the control module can be used to control the output power of the roller feeding motor 132 through the third frequency converter 403, thereby controlling the rotation speed of the conveying roller 131, and coordinating with the conveying speed of the conveyor belt mechanism 110 to realize the orderly feeding of the tobacco placed on the conveyor belt mechanism 110. At the same time, when no feeding is required, the conveying roller 131 can be used to block the continuous feeding of the tobacco moving on the conveyor belt mechanism 110.

[0052] In this embodiment, the first proximity switch 171, the second proximity switch 172, and the third proximity switch 173 are sequentially installed along the conveying direction of the conveyor belt mechanism 110 before the conveying roller 131 and below the inner surface of the enclosure 140, so that when the tobacco is stored in different positions, the control module controls the output power of the roller conveying motor 132 through the third inverter 403; for example, Fig.12 In the steps S107, S108, S109, S110, S111 and S112 shown, when the tobacco is stored at the position of the third proximity switch 173, the control module controls the roller feed motor 132 to have a higher output power through the third frequency converter 403, thereby increasing the rotation speed of the conveying roller 131 and increasing the feeding speed; when the tobacco is stored at the position of the first proximity switch 171, the control module controls the roller feed motor 132 to have a lower output power through the third frequency converter 403, thereby reducing the rotation speed of the conveying roller 131 and reducing the feeding speed, thereby preventing the conveying roller 131 from idling.

[0053] Specifically, in order to improve the uniformity of tobacco feeding and avoid uneven feeding caused by tobacco clumping together, the conveying roller 131 in this embodiment includes a roller body 131a and a number of rake rods 131b, one end of the rake rod 131b is connected to the roller body 131a, and the other end extends in the radial direction of the roller body 131a away from the roller body 131a, and a number of rake rods 131b are distributed on the outer circumferential surface of the roller body 131a at intervals. In this way, the roller body 131a can continuously rotate under the action of the roller feeding motor 132, and drive the rake rod 131b to rotate. During the rotation of the rake rod 131b, the tobacco clumped together can be dispersed, thereby evenly moving to the downstream tobacco feeding device 200, so that the feeding is more uniform.

[0054] Furthermore, there is a gap between one end of the rake rod 131b away from the roller body 131a and the conveying surface of the conveyor belt mechanism 110. On the one hand, it avoids scratching with the conveying surface of the conveyor belt mechanism 110, which may cause damage to the conveying surface of the conveyor belt mechanism 110 after long-term use, thereby improving the service life of the equipment. On the other hand, it can form a space for tobacco to pass through, so that the tobacco can pass through the gap between the two rake rods 131b and the gap between the rake rod 131b and the conveying surface of the conveyor belt mechanism 110, thereby improving the efficiency of tobacco feeding.

[0055] In this embodiment, the conveyor belt mechanism 110 includes a conveyor belt 111, a conveyor transmission assembly 112 and a conveyor motor 113. The conveyor transmission assembly 112 includes a conveyor belt 112a, a conveyor driving wheel 112b, a conveyor driven wheel 112c, a conveyor pressure wheel 112d and a conveyor support wheel 112e. The conveyor motor 113 is connected to the conveyor driving wheel 112b. The conveyor belt 112a is arranged around the conveyor driving wheel 112b and the conveyor driven wheel 112c, and cooperates with the conveyor support wheel 112e and the conveyor pressure wheel 112d to tension the conveyor belt 112a to achieve stable power output between the conveyor driven wheel 112c and the conveyor driving wheel 112b. The conveyor belt 111 is wound around the conveyor driven wheel 112c and the conveyor driving wheel 112b to achieve orderly circular rotation and convey tobacco.

[0056] Among them, the tobacco conveying device 100 also includes a conveying bracket 150, and the conveying belt mechanism 110 is installed on the conveying bracket 150. The bottom of the conveying bracket 150 is connected to a conveying wheel 160. In this way, the conveying belt mechanism 110 can be moved to the processing position through the conveying bracket 150 and the conveying wheel 160, which is more convenient to use.

[0057] refer to Figure 6-Figure 7 Furthermore, the tobacco feeding device 200 in this embodiment includes a first feeding belt mechanism 210, a second feeding belt mechanism 220 and a support assembly 230. The discharge end of the first feeding belt mechanism 210 is hinged to the feed end of the second feeding belt mechanism 220 so as to be relatively rotatable, so that under the conditions of transportation or different operating conditions, the inclination of the second feeding belt mechanism 220 can be adjusted for transportation and movement, or the height of the discharge end of the second feeding belt mechanism 220 from the ground can be adjusted to adapt to the height of different downstream equipment;

[0058] Specifically, the support assembly 230 includes a first support rod 231, a second support rod 232 and a support seat 233. One end of the first support rod 231 is hinged to the second feeding belt mechanism 220, and the other end is hinged to the second support rod 232. The end of the second support rod 232 away from the first support rod 231 is hinged to the support seat 233. By rotating the hinge position of the first support rod 231 and the second support rod 232, the height of the first support rod 231 and the second support rod 232 when connected is adjusted, thereby realizing the adjustment of the height of the discharge end of the second feeding belt mechanism 220. In addition, in order to lock the first feeding belt mechanism 210 and the second feeding belt mechanism 220 after adjustment, The relative positions of the two feeding belt mechanisms 220, the first support rod 231 and the second support rod 232 are both provided with locking holes 234 for locking. When the relative positions of the first feeding belt mechanism 210 and the second feeding belt mechanism 220 are determined, the positions of the first support rod 231 and the second support rod 232 can be fixed by inserting bolts between the two locking holes 234, thereby locking the positions of the first feeding belt mechanism 210 and the second feeding belt mechanism 220. It should be noted that the tobacco feeding device 300 is arranged at the discharge end of the second feeding belt mechanism 220, and the first feeding belt mechanism 210 and the second feeding belt mechanism 220 are electrically connected to the control module.

[0059] In the present embodiment, the first feeding belt mechanism 210 and the second feeding belt mechanism 220 both include a feeding conveyor belt 211, which has a conveying surface, and the conveying surface is provided with a plurality of guide blocks 212 arranged in sequence along the feeding direction. When the tobacco is conveyed from the tobacco conveying device 100 to the tobacco feeding device 200, the tobacco is conveyed on the feeding conveyor belt 211. The guide blocks 212 arranged on the conveying surface can stably push the tobacco to move upwards to prevent the tobacco from slipping during the movement.

[0060] Wherein, both sides of the first feeding belt mechanism 210 and the second feeding belt mechanism 220 are provided with guard plates 213 to prevent tobacco from falling from both sides.

[0061] Furthermore, the tobacco feeding device 200 also includes a hinged support 240, which includes a supporting side plate 241. The discharge end of the first feeding belt mechanism 210 is fixedly connected to the supporting side plate 241, and the feed end of the second feeding belt mechanism 220 is hinged to the supporting side plate 241 to form a hinge axis. The supporting side plate 241 is provided with at least one arc-shaped guide groove 242, and the arc-shaped guide groove 242 is arranged concentrically with the hinge axis. The arc-shaped guide groove 242 is penetrated by a locking piece 243 for locking the second feeding belt mechanism 220 and the supporting side plate 241, which can further improve the stability and rotation reliability of the first feeding belt mechanism 210 and the second feeding belt mechanism 220 when connected.

[0062] Specifically, the tobacco feeding device 200 also includes a feeding transmission assembly 250, which includes a feeding motor 251, a feeding driving wheel 252, a feeding driven wheel 253, a feeding guide wheel 254, a feeding pressure wheel 255 and a feeding belt. The feeding belt is arranged around the feeding driving wheel 252 and the feeding driven wheel, and the feeding belt is tensioned by the feeding guide wheel 254 and the feeding guide wheel 254, and the feeding conveyor belt 211 is arranged around the feeding driven wheel 253 and the feeding driving wheel 252, so as to realize feeding by driving the feeding driving wheel 252 to rotate in a circle through the feeding motor 251.

[0063] In addition, casters are installed at the bottom of the tobacco feeding device 200 for movement, making it more flexible to use.

[0064] refer to Figure 8-Figure 11 , Fig.13 The tobacco feeding device 300 in this embodiment includes a storage frame 310, a distribution funnel 320, a distribution assembly 330 and a support frame 340.

The distribution funnel 320 is provided at the discharge port. The distribution assembly 330 is provided in the storage frame 310 for feeding the distribution funnel 320. The storage frame 310 is provided with a first feeding detection unit arranged in sequence along its feeding direction. 350 and the second feeding detection unit 360, the first feeding detection unit 350 and the second feeding detection unit 360 are electrically connected to the control module, and in the corresponding circuit diagram, include a material level detection terminal J, a material level detection terminal K, a negative pressure detection terminal M and a frequency converter enable terminal L, a frequency converter enable terminal N, wherein the material level detection terminal J, the material level detection terminal K, and the negative pressure detection terminal M are digital input signals, and the frequency converter enable terminal L, the frequency converter enable terminal N are digital output signals. Fig.13 As shown in steps S302 and S303, when the first feeding detection unit 350 obtains that the tobacco in the storage frame 310 reaches the third preset value, the control module controls the tobacco feeding device 200 to stop feeding through the frequency converter 404. As shown in steps S301 and S303, when the second feeding detection unit obtains that the tobacco in the storage frame 310 is less than the fourth preset value, the control module controls the tobacco feeding device 200 to start feeding through the frequency converter 404, thereby realizing orderly feeding of tobacco in the tobacco feeding device 300.

[0065] Furthermore, in order to improve the stable feeding of tobacco in the tobacco feeding device 300, the material distribution assembly 330 includes a material distribution motor 331, a material distribution roller 332, a first guide plate 333 and a second guide plate 334.
