Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0043] Combine the following Figure 1-Figure 6 , describing the unloading mechanism provided in the embodiments of the present application.

[0044] Reference Figure 1 , Figure 2As shown, the unloading mechanism provided in the embodiment of the present application includes a base rod 100, a first connecting rod 200, a second connecting rod 300 and a unloading tube 400, one end of the first connecting rod 200 is rotatably connected to the base rod 100; one end of the second connecting rod 300 is rotatably connected to the base rod 100; the outer wall of the unloading tube 400 is rotatably connected to the other end of the first connecting rod 200 and the other end of the second connecting rod 300 respectively, at least part of the base rod 100, the first connecting rod 200, and the second connecting rod 300 together form a triangle; the first connecting rod 200 and the second connecting rod 300 can respectively extend and retract along their own axes to move the unloading tube 400 to adjust the position of the unloading tube 400. In some of the specific embodiments, the base rod 100 can be fixed on the frame of the mixer, and two hinge seats are provided on the base rod 100. The first connecting rod 200 and the second connecting rod 300 are respectively hinged to the corresponding hinge seats through a pin shaft, so that the upper end of the first connecting rod 200 and the upper end of the second connecting rod 300 can rotate around the corresponding pin shaft respectively; a hinge seat is provided on the outer wall of the discharge pipe 400, and the lower end of the first connecting rod 200 and the lower end of the second connecting rod 300 are respectively connected to the hinge seat through a pin shaft, so that the lower end of the first connecting rod 200 and the lower end of the second connecting rod 300 can rotate around the pin shaft respectively; in some of the specific embodiments, the first connecting rod 200 and the second connecting rod 300 are telescopic rods, and the discharge pipe 400 can be driven to move by changing the length of the first connecting rod 200 and the second connecting rod 300. In some specific embodiments, the feed pipe 400 includes a connecting section 410 and a discharging section 420. The starting end of the connecting section 410 is used to be connected to the discharging port of the mixer, and the end of the connecting section 410 is connected to the starting end of the discharging section 420. The connecting section 410 adopts a telescopic hose, and the discharging section 420 is conveniently connected to the discharging port of the mixer through the telescopic hose. The discharging section 420 is respectively connected to the first connecting rod 200 and the second connecting rod 300.

[0045] By utilizing the technical solution of the above-mentioned embodiment, the feed pipe 400 is connected to the first connecting rod 200 and the second connecting rod 300 respectively, so that the base rod 100, the first connecting rod 200 and the second connecting rod 300 form a triangle together, and the stability of the triangle is used to fix the position of the feed pipe 400, thereby avoiding displacement of the feed pipe 400 due to vibration during the feeding process, effectively reducing the frequency of adjustment and maintenance of the position of the feed pipe 400, and reducing the number of equipment shutdowns; the feed pipe 400 is moved accordingly by making the first connecting rod 200 and the second connecting rod 300 respectively extend and retract along their own axes to adjust the position of the feed pipe 400, thereby achieving precise adjustment of the position of the feed pipe 400.

[0046] Reference Figure 4As shown, in some embodiments of the present application, the first connecting rod 200 and the second connecting rod 300 respectively include a sleeve 210, an adjusting rod 220 and an anti-slipping member 230, wherein the outer bottom wall of the sleeve 210 is rotatably connected to the base rod 100; one end of the adjusting rod 220 is arranged in the sleeve 210, and the outer wall of the adjusting rod 220 is threadedly connected to the inner wall of the sleeve 210; the anti-slipping member 230 is arranged at the other end of the adjusting rod 220, and is used to be connected to the outer wall of the feeding tube 400. In this way, by making the adjusting rod 220 and the sleeve 210 rotate relative to each other, the length of the adjusting rod 220 in the sleeve 210 is changed, thereby changing the overall length of the adjusting rod 220 and the sleeve 210, that is, the length of the first connecting rod 200 and the second connecting rod 300 is adjusted. In some specific embodiments, the first connecting rod 200 and the second connecting rod 300 further include a pressure spring 250, one end of which abuts against the inner bottom wall of the sleeve 210, and the other end of which abuts against the end of the adjusting rod 220 close to the sleeve 210. In this way, by utilizing the compression elastic force of the pressure spring 250, the pressure spring 250 can exert an axial force on the adjusting rod 220, which is conducive to increasing the friction between the external thread of the adjusting rod 220 and the internal thread of the sleeve 210 under the pressure of the axial force, so that the external thread of the adjusting rod 220 and the internal thread of the sleeve 210 are more tightly engaged, thereby effectively preventing the adjusting rod 220 and the sleeve 210 from loosening during the blanking process.

[0047] Reference Figure 2 As shown, in some embodiments of the present application, the anti-slip component 230 includes a snap ring 231 and an anti-slip hook 232. The snap ring 231 is sleeved on the outer wall of the discharge pipe 400, and the snap ring 231 has a connecting portion 240; the anti-slip hook 232 is arranged at one end of the adjusting rod 220 close to the discharge pipe 400, and is used for detachable connection with the connecting portion 240. In some specific embodiments, an annular groove is provided on the outer wall of the feed tube 400, and the snap ring 231 is sleeved in the annular groove, and the inner wall of the snap ring 231 is matched with the groove bottom of the annular groove. Since the feed tube 400 is a silicone product, based on the soft nature and anti-slip properties of the silicone product, the snap ring 231 can be quickly sleeved on the outer wall of the feed tube 400 to fix the snap ring 231, and the snap ring 231 can be prevented from moving on the feed tube 400; in some specific embodiments, the connecting portion 240 can be a connecting hook or a connecting hole, for example, a connecting hole is provided on the snap ring 231, and the anti-detachment hook 232 is hooked at the connecting hole to realize a detachable connection between the anti-detachment hook 232 and the snap ring 231. In this way, it is convenient to replace the feed tube 400 or disassemble and replace the anti-detachment hook 232 and the snap ring 231.

[0048] Reference Figure 3As shown, in some embodiments of the present application, there are at least two connecting parts 240, at least one connecting part 240 is arranged on a side of the snap ring 231 close to the first connecting rod 200, and at least one connecting part 240 is arranged on a side of the snap ring 231 close to the second connecting rod 300; Figure 3 As shown, there are two connecting parts 240, one of which is disposed on one side of the snap ring 231 close to the first connecting rod 200 ( Figure 3 The other connecting portion 240 is disposed on one side of the snap ring 231 close to the second connecting rod 300 ( Figure 3 In this way, by providing two connecting parts 240, the first connecting rod 200 and the second connecting rod 300 are respectively connected to the feeding tube 400 on the left and right sides thereof, thereby realizing double-point fixation. Compared with single-point fixation, the feeding tube 400 is more stable. In some specific embodiments, the connecting portion 240 includes a connecting ear 241 and an extrusion block 242, the connecting ear 241 is arranged on the outer side of the retaining ring 231, and the connecting ear 241 is formed with a middle hole; the extrusion block 242 is arranged in the middle hole of the connecting ear 241, and a gap is formed on the extrusion block 242, and the gap is used to allow the anti-detachment hook 232 to pass through; specifically, the extrusion block 242 is fan-shaped, and multiple extrusion blocks 242 are arranged on the inner wall of the middle hole, and there is a gap between two adjacent extrusion blocks 242, wherein the extrusion block 242 is made of elastic material, such as silicone, so that when the anti-detachment hook 232 enters, due to the elastic texture of the extrusion block 242, the anti-detachment hook 232 can slide into the gap between the two adjacent extrusion blocks 242 and be stuck between the two adjacent extrusion blocks 242, so that the anti-detachment hook 232 can basically not shake on the connecting ear 241, thereby having a better stabilizing effect on the feeding tube 400.

[0049] Refer to 4. Figure 5As shown, in some embodiments of the present application, the first connecting rod 200 and the second connecting rod 300 also include a shock absorbing assembly 260, respectively. The shock absorbing assembly 260 is arranged at one end of the adjusting rod 220 close to the discharge pipe 400. The shock absorbing assembly 260 includes a shock absorbing cylinder 261, a retaining ring 262 and an axial buffer spring 263. One end of the shock absorbing cylinder 261 is used to install the anti-slip component 230, and the other end of the shock absorbing cylinder 261 is provided with a guide hole 2611. The adjusting rod 220 is inserted into the guide hole 2611, so that at least part of the adjusting rod 220 is arranged in the shock absorbing cylinder 261; the retaining ring 262 is protrudingly arranged on the side wall of the adjusting rod 220 outside the shock absorbing cylinder 261; one end of the axial buffer spring 263 abuts against the retaining ring 262, and the other end abuts against one end of the shock absorbing cylinder 261 having the guide hole 2611. It should be noted that due to the vibration of the feed tube 400, the first connecting rod 200, the second connecting rod 300 and the base rod 100 will be subjected to axial or radial stress. By respectively arranging the shock absorbing assembly 260 on the first connecting rod 200 and the second connecting rod 300, the stress caused by the vibration of the feed tube 400 can be reduced, and the loss to the first connecting rod 200, the second connecting rod 300 and the base rod 100 can be reduced. Specifically, the lower end of the adjusting rod 220 has an end cover, and the diameter of the end cover is larger than the diameter of the guide hole 2611; in this way, under the axial elastic force of the axial buffer spring 263, the end cover maintains contact with the inner upper wall of the shock-absorbing cylinder 261, and due to the pressing force of the axial buffer spring 263, it can prevent the discharge pipe 400 from vibrating; when the vibration of the discharge pipe 400 is large, the shock-absorbing cylinder 261 squeezes the axial buffer spring 263, and the axial buffer spring 263 is compressed, thereby offsetting the axial vibration of the discharge pipe 400, and reducing the stress loss caused by the vibration of the discharge pipe 400 to the first connecting rod 200, the second connecting rod 300 and the base rod 100.

[0050] Reference Figure 6As shown, in some embodiments of the present application, the shock absorbing assembly 260 also includes a radial buffer spring 264, which is evenly distributed in a ring shape on the inner wall of the guide hole 2611, and one end of the radial buffer spring 264 abuts against the inner wall of the guide hole 2611, and the other end abuts against the outer wall of the adjusting rod 220. In some specific embodiments, the number of radial buffer springs 264 is three, and the length direction of each radial buffer spring 264 is arranged along the radial direction of the guide hole 2611. Correspondingly, a third groove is opened on the inner wall of the guide hole 2611, and one end of the radial buffer spring 264 is respectively arranged in the corresponding groove, and the other end of the radial buffer spring 264 is respectively connected with an arc piece 265. In this way, under the radial elastic force of the radial buffer spring 264, the three arc pieces 265 can surround the outer wall of the adjusting rod 220, so as to limit the adjusting rod 220. At the same time, when the vibration of the lower feeding tube 400 is large, the adjusting rod 220 squeezes one or two radial buffer springs 264 to compress the corresponding radial buffer spring 264, thereby offsetting the radial vibration of the lower feeding tube 400 and reducing the stress loss caused by the vibration of the lower feeding tube 400 to the first connecting rod 200, the second connecting rod 300 and the base rod 100.

[0051] The workflow of the unloading mechanism of this application:

[0052] Fix the base rod 100 on the frame of the mixer, and roughly adjust the length of the first connecting rod 200 and the second connecting rod 300;

[0053] One end of the feed pipe 400 is connected to the discharge port of the mixer, and the other end is connected to the first connecting rod 200 and the second connecting rod 300 respectively;

[0054] The lengths of the first connecting rod 200 and the second connecting rod 300 are precisely adjusted to move the feeding pipe 400 to the target position and wait for the mixer to discharge the material.

[0055] Beneficial effects of the feeding mechanism of this application:

[0056] 1. By making the base rod 100, the first connecting rod 200 and the second connecting rod 300 form a triangle together, the position of the feeding tube 400 is fixed by utilizing the stability of the triangle, so as to avoid displacement of the feeding tube 400 due to vibration during the feeding process, so that the feeding tube 400 can maintain a high stability, reduce the vibration of the feeding tube 400, and effectively avoid the slurry in the feeding tube 400 from splashing out, thereby preventing the splashed slurry from falling back into the feeding tube 400 and damaging the face paper, effectively reducing the downtime frequency and improving the production efficiency;

[0057] 2. The first connecting rod 200 and the second connecting rod 300 are respectively extended and retracted along their own axes so that the feeding tube 400 moves accordingly to adjust the position of the feeding tube 400, thereby realizing accurate adjustment of the position of the feeding tube 400;

[0058] 3. By providing the axial buffer spring 263 and the radial buffer spring 264, the axial vibration and radial vibration of the discharge pipe 400 can be offset, and the stress loss caused by the vibration of the discharge pipe 400 to the first connecting rod 200, the second connecting rod 300 and the base rod 100 can be reduced.
