Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As Figures 1 - 10As shown in the figure, a PVC granule feeding conveyor for low-smoke and halogen-free sheath processing provided by an embodiment of the present invention includes a bottom plate 101. A bracket 102 is fixedly arranged on the upper surface of the bottom plate 101, and a mounting frame 103 is rotatably connected in the bracket 102. A driving motor 105 is fixedly arranged on the outer wall of the mounting frame 103, and a shaft roller 106 is rotatably arranged at the driving end of the driving motor 105. The shaft roller 106 is rotatably arranged in the mounting frame 103. A telescopic cylinder 120 is also fixedly arranged on the outer wall of the mounting frame 103, and a tensioning roller 121 is fixedly installed at the telescopic end of the telescopic cylinder 120. The tensioning roller 121 is rotatably arranged in the mounting frame 103. A conveyor belt 107 is sleeved outside the shaft roller 106 and the tensioning roller 121, and hoppers 108 are fixedly arranged on the outer wall of the conveyor belt 107 at equal intervals. A fixed frame 104 is also rotatably connected outside the mounting frame 103. A feeding box 109 is fixedly arranged on the upper surface of the bottom plate 101, and a return material port 110 is opened on one side of the feeding box 109, and the bottom end of the mounting frame 103 is located in the return material port 110. A guide pipe 111 is communicated with the outer wall of one side of the feeding box 109, and a round hopper 112 is communicated with the end of the guide pipe 111. A support rod 113 is also fixedly arranged on the upper surface of the bottom plate 101, and a support seat 114 is fixedly arranged at the top end of the support rod 113. A storage tank 115 is arranged above the support seat 114. A support leg 117 is fixedly arranged at the bottom end of the storage tank 115, and a moving wheel 119 is fixedly arranged at the bottom end of the support leg 117. The disk 118 and the support seat 114 cooperate with each other. It also includes: a conveying mechanism arranged in the feeding box 109 for conveying the materials in the feeding box 109 to the hoppers 108; a conducting mechanism arranged in the blanking cylinder 116 for automatically removing the blockage of the blanking cylinder 116 when the blanking cylinder 116 is docked with the round hopper 112, so that the materials in the storage tank 115 are introduced into the round hopper 112 through the blanking cylinder 116; a loading and unloading mechanism arranged above the bottom plate 101 for loading and unloading the storage tank 115.

[0031] The fixing bracket 104 can be fixed at the feeding port of the sheath processing equipment. Then, through the loading and unloading mechanism, the storage tank 115 can be loaded above the round hopper 112, so that the feeding tube 116 below the storage tank 115 is docked with the round hopper 112, and the supporting legs 117 at the bottom of the storage tank 115 are lifted by the supporting seat 114. And when the feeding tube 116 and the round hopper 112 are docked, the blockage of the feeding tube 116 can be automatically released under the action of the conduction mechanism, so that the materials in the storage tank 115 are introduced into the round hopper 112 through the feeding tube 116, and then enter the feeding box 109 along the material guiding pipe 111. At this time, through the conveying mechanism, the materials in the feeding box 109 can be introduced into the hopper 108. At the same time, the driving motor 105 can drive the shaft roller 106 to rotate, so that the conveyor belt 107 rotates together, and the hopper 108 can be conveyed to the feeding port of the sheath processing equipment. At the same time, the hopper 108 is turned over, so that the materials in the hopper 108 are poured into the feeding port of the sheath processing equipment to realize the feeding operation. And through the telescopic cylinder 120, the tensioning roller 121 can be driven to move, and the tension of the conveyor belt 107 can be adjusted, so that the conveyor belt 107 rotates more stably. During the process of the conveying mechanism introducing the materials into the hopper 108, the hopper 108 will be gradually filled with materials, and the excess materials will overflow from the hopper 108 and re-enter the feeding box 109 through the return port 110, effectively realizing the quantitative feeding of PVC particles, improving the uniformity and stability of feeding, and having better use effect. And when it is necessary to replace the storage tank 115 after all the materials in the storage tank 115 are introduced into the feeding box 109, the storage tank 115 can be quickly unloaded and replaced with a new storage tank 115 by means of the loading and unloading mechanism. At the same time, during the process of replacing the storage tank 115, the materials temporarily stored in the feeding box 109 can still ensure continuous feeding and will not affect the continuity of feeding, effectively ensuring the continuity of the production process and the stability of the product quality, and having better use effect.

[0032] As an embodiment of the present invention, please refer to Figure 2 , Figure 5 and Figure 6 , the conveying mechanism includes a lifting cylinder 201 obliquely fixed in the feeding box 109. The top end of the lifting cylinder 201 is fixedly provided with a servo motor 202, and the output end of the servo motor 202 is rotationally connected with a rotating shaft 203. The rotating shaft 203 is rotatably arranged in the lifting cylinder 201, and the outer wall of the rotating shaft 203 is fixedly connected with a screw blade 204. The side wall of the lifting cylinder 201 is also communicated with a discharge frame 205 aligned with the hopper 108. When it is necessary to introduce the materials in the feeding box 109 into the hopper 108, the servo motor 202 can be driven to drive the rotating shaft 203 to rotate, and the rotating shaft 203 drives the screw blade 204 to rotate, so that the materials at the bottom of the feeding box 109 can be lifted into the lifting cylinder 201 and discharged into the hopper 108 through the discharge frame 205, which is very convenient to use.

[0033] As an embodiment of the present invention, please refer to Figure 6 , a deflector 301 is fixedly arranged in the material feeding box 109 and is used for guiding the material falling back into the material feeding box 109 to the bottom end of the lifting cylinder 201. A partition plate 302 is also fixedly arranged in the material feeding box 109 and is used for promoting the material introduced into the material feeding box 109 to accumulate on one side of the partition plate 302 to block the material guiding pipe 111. When the material is introduced into the material feeding box 109 through the material guiding pipe 111, the material will accumulate on one side of the partition plate 302 until the height of the material exceeds the material guiding pipe 111, and then the material guiding pipe 111 will be automatically blocked, only allowing a certain amount of material to be introduced into the material feeding box 109, effectively avoiding the situation that too much introduced material overflows from the return material port 110. Moreover, part of the material falling back into the material feeding box 109 can also be quickly guided to the bottom end of the lifting cylinder 201 under the guiding action of the deflector 301 and be lifted again by the lifting cylinder 201, with better use effects.

[0035] As an embodiment of the present invention, please refer to Figure 5 , Figure 7 , Figure 8 and Figure 9The conducting mechanism includes a vertical rod 401 fixedly arranged on the upper surface of the bottom plate 101, and the vertical rod 401 passes through the guide tube 111, a top block 402 is fixedly arranged on the top of the vertical rod 401, and the top block 402 is located in the round bucket 112, and the inner wall of the lower barrel 116 is fixedly provided with fixed rods 403 distributed in an annular shape with equal distances, and a fixed ring 404 is fixedly arranged on the end of the fixed rod 403, a telescopic rod 405 is movably arranged in the fixed ring 404, and a sealing block 407 is fixedly arranged on the top of the telescopic rod 405, and a first spring 406 is sleeved on the outer side of the telescopic rod 405, one end of the first spring 406 is connected to the upper surface of the fixed ring 404, and the other end of the first spring 406 is connected to the sealing block 407. The lower surface of the support leg 117 is connected to the lower surface of the support leg 117, and when the lower barrel 116 below the storage tank 115 is docked with the round bucket 112, the lower barrel 116 will first enter the round bucket 112. At this time, the top block 402 in the round bucket 112 will lift the telescopic rod 405, so that the first spring 406 is stretched. At this time, the sealing block 407 will move up together to release the blockage of the lower barrel 116, so that the material in the storage tank 115 is introduced into the round bucket 112 along the lower barrel 116, and as the storage tank 115 moves further downward, the disc 118 at the bottom of the supporting leg 117 will be stuck in the supporting seat 114, which plays a role in lifting the storage tank 115, so that the material in the storage tank 115 is stably introduced into the round bucket 112, which is very convenient to use.

[0036] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 8, the loading and unloading mechanism includes a slide rail 501 fixedly arranged on the upper surface of the bottom plate 101, and a slider 502 is slidably arranged in the slide rail 501. A hydraulic cylinder 503 is fixedly arranged on the upper surface of the slider 502, and a support frame 504 is fixedly arranged at the telescopic end of the hydraulic cylinder 503. A side plate 507 is fixedly arranged on the side wall of the storage tank 115, and a clamping block 508 is fixedly arranged on the lower surface of the side plate 507. A clamping groove 505 matching with the clamping block 508 is formed on the upper surface of the support frame 504. A stop rod 506 is also fixedly arranged in the slide rail 501 for blocking the slider 502, and when blocking, the clamping block 508 just aligns with the clamping groove 505. A limiting port 509 is also formed on the side wall of the bottom plate 101, and the disc 118 and the limiting port 509 are matched with each other. When it is necessary to load the storage tank 115, the storage tank 115 can be directly pushed, so that the disc 118 at the bottom of the storage tank 115 enters the limiting port 509 on one side of the bottom plate 101, and the position of the storage tank 115 can be quickly limited. Then, the slider 502 in the slide rail 501 can be moved, so that the support frame 504 moves to the outside of the storage tank 115, and the clamping block 508 aligns with the clamping groove 505. Then, the support frame 504 can be lifted by the hydraulic cylinder 503, so that the clamping block 508 below the side plate 507 enters the clamping groove 505, and the storage tank 115 can be lifted by the support frame 504. Then, the slider 502 is moved again until the slider 502 is blocked by the stop rod 506. At this time, the blanking cylinder 116 just aligns with the round hopper 112. Then, the support frame 504 is driven to move downward by the hydraulic cylinder 503 again. At this time, the blanking cylinder 116 will be docked with the round hopper 112. At the same time, the disc 118 enters the support seat 114, so that the support seat 114 plays a role in supporting the storage tank 115, effectively realizing the rapid loading of the storage tank 115, and the use effect is better.

[0037] As an embodiment of the present invention, please refer to Figure 7 and Figure 8, a movable rod 601 is also movably arranged through the outer wall of the storage tank 115.

One side outer wall of the push plate 604 close to the limit frame 603 is also fixedly provided with a touch switch 606. When replenishing the material in the storage tank 115, the push plate 604 can be pushed first to stretch the second spring 605. When the material accumulates in the storage tank 115, the material can play a role in hindering the movement of the displacement piece 602. When the material in the storage tank 115 gradually drops below the displacement piece 602, the displacement piece 602 will move under the reset action of the second spring 605, so that the touch switch 606 on one side of the push plate 604 contacts the limit frame 603. The touch switch 606 is electrically connected to an alarm, which can timely remind the staff to prepare for replacing the storage tank 115, and the use effect is better.

[0038] When in use, the fixing frame 104 can be fixed to the feeding port of the sheath processing equipment, and then the storage tank 115 can be loaded onto the top of the round bucket 112 through the loading and unloading mechanism, so that the lower barrel 116 below the storage tank 115 is connected with the round bucket 112, and the support legs 117 at the bottom of the storage tank 115 are lifted by the support seat 114, and when the lower barrel 116 and the round bucket 112 are connected, the blocking of the lower barrel 116 can be automatically released under the action of the conduction mechanism, so that the storage tank The material in 115 is introduced into the round bucket 112 through the lower barrel 116, and then enters the feed box 109 along the guide pipe 111. At this time, the material in the feed box 109 can be introduced into the hopper 108 through the conveying mechanism. At the same time, the drive motor 105 can drive the shaft roller 106 to rotate, so that the conveyor belt 107 rotates together, and the hopper 108 can be transported to the feeding port of the sheath processing equipment. At the same time, the hopper 108 is turned over, so that the material in the hopper 108 is poured into the sheath processing equipment. The feeding operation is realized in the feeding port of the equipment, and the tensioning roller 121 can be driven to move by the telescopic cylinder 120, and the tension of the conveyor belt 107 can be adjusted, so that the conveyor belt 107 is more stable when rotating. In the process of the conveying mechanism introducing the material into the hopper 108, the material will gradually fill up the hopper 108, and the excess material will overflow from the hopper 108 and re-enter the feed box 109 through the return port 110, thereby effectively realizing the quantitative feeding of PVC particles, improving the uniformity and stability of the feeding, and having a better use effect. Moreover, when the material in the storage tank 115 is completely introduced into the feed box 109 and the storage tank 115 needs to be replaced, the storage tank 115 can be quickly unloaded and replaced with a new storage tank 115 with the help of the loading and unloading mechanism.
