DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0022] See also Figure 1-7 , the present invention provides a technical solution: An automatic feeding device for a PVC film calendering machine comprises a storage tank 1, four support columns 13 are fixedly connected to the lower end of the storage tank 1, a mounting seat 12 is fixedly connected to the lower end of the four support columns 13, a mounting hole 14 is arranged at the upper end of the mounting seat 12, and the mounting seat 12 is connected to the melting port of the calendering machine, a discharge port 40 is arranged at the lower end of the storage tank 1, and a collecting cylinder 21 is fixedly connected to the lower end of the storage tank 1, and a quantitative discharge adjustment component is arranged at the bottom of the collecting cylinder 21; The quantitative discharge adjustment component includes U-shaped fixed blocks 20 symmetrically fixed on both sides of the lower end of the collecting cylinder 21, and the inner cavity of each U-shaped fixed block 20 is rotatably connected to a rotating rod 19, one end of one rotating rod 19 is fixedly connected to a first sealing cover 17, and one end of the other rotating rod 19 is fixedly connected to a second sealing cover 18, and the first sealing cover 17 and the second sealing cover 18 cooperate to seal the bottom end of the collecting cylinder 21; the other end of each rotating rod 19 is fixedly connected to a traction rope 31, and each of the traction ropes 31 is fixedly connected to a plug column 30 at one end away from the rotating rod 19.

[0023] Specifically, in the prior art, before the production of PVC film, a feeding device is used to feed the raw materials for PVC film production into a calender, and the raw materials are heated and melted to form a soft material, and then the soft material is discharged into the roller of the calender, and at the same time, the roller of the calender is subjected to multiple rolling to form a film of a desired thickness, and the film is quickly cooled by a cooling device, and then rolled and packaged by a winding device. However, when the raw materials for PVC film production are discharged into the calender, it is inconvenient to discharge the raw materials quantitatively, resulting in excessive raw materials entering the calender, which easily causes uneven melting of the raw materials, resulting in quality problems of the film formed by rolling the roller of the calender; When the present invention processes and produces PVC film, the storage tank 1 is installed above the melting port of the calender by using the mounting seat 12, and is fixed to the calender by penetrating the mounting hole 14 with an external bolt, and then the raw material in the inner cavity of the storage tank 1 falls into the inner cavity of the collecting cylinder 21 through the discharge port 40. After storing a certain amount of raw material, the first sealing cover 17 and the second sealing cover 18 cannot withstand the weight of the raw material and drive the rotating rod 19 to flip in the inner cavity of the U-shaped fixing block 20. At the same time, during the flipping process, the rotating rod 19 pulls the traction rope 31 to move, and the traction rope 31 drives the plug 30 to rotate, thereby opening the collecting cylinder 21 to discharge the raw material in the inner cavity, and then the raw material falls into the melting port of the calender for melting treatment, thereby solving the problem that when the existing PVC film calender automatic feeding device discharges the PVC film production raw material into the calender, it is inconvenient to discharge the raw material quantitatively, resulting in excessive raw material entering the interior of the calender, which easily causes uneven melting of the raw material.

[0024] like Figures 1 to 4As shown, U-shaped fixing frames 15 are fixedly connected to both sides of the upper end of the mounting seat 12, and the inner cavities of the two U-shaped fixing frames 15 are fixedly connected to the adjusting cylinders 16. The plug 30 is rotatably connected in the inner cavities of the adjusting cylinders 16, and the first sealing cover 17 and the second sealing cover 18 are provided with rubber pads near one end of the collecting cylinder 21.

[0025] Specifically, when the PVC film is processed and produced, the storage tank 1 discharges the raw materials into the collecting cylinder 21 through the discharge port 40 for storage. After a certain amount of raw materials are stored in the inner cavity of the collecting cylinder 21, the first sealing cover 17 and the second sealing cover 18 cannot withstand the weight of the raw materials and drive the rotating rod 19 to flip in the inner cavity of the U-shaped fixed block 20, thereby opening the collecting cylinder 21 to discharge the raw materials in the inner cavity. After the raw materials in the inner cavity of the collecting cylinder 21 are discharged, the plug column 30 is driven to rotate, and the plug column 30 drives the traction rope 31 to be reeled up, and then the traction rope 31 pulls the rotating rod 19 to reset. At the same time, during the resetting process, the rotating rod 19 drives the first sealing cover 17 and the second sealing cover 18 to flip and reset, and then the collecting cylinder 21 is sealed again, and then the raw materials are collected and stored again, thereby ensuring the efficiency of the calender in melting the raw materials and avoiding the situation where the raw materials are not completely melted.

[0026] like Figures 2 to 4 As shown, threaded rods 24 are rotatably connected to the inside of the U-shaped fixing frame 15 at both ends, a knob 23 is fixedly connected to the end of the threaded rod 24 away from the U-shaped fixing frame 15, and a threaded sleeve 25 is externally threadedly connected to one end of the threaded rod 24 located in the inner cavity of the adjusting cylinder 16. The inner cavity of the adjusting cylinder 16 is provided with a first fixed plate 26 and a second fixed plate 27, and the first fixed plate 26 and the second fixed plate 27 are fixedly connected to the threaded sleeve 25 at one end away from each other.

[0027] Specifically, when the discharge amount of the raw material needs to be adjusted, the driving knob 23 is rotated, and the knob 23 drives the threaded rod 24 to rotate, and then the threaded rod 24 is threadedly driven to disengage the threaded sleeve 25. When the threaded sleeve 25 is threadedly disengaged from the threaded rod 24, the first fixed disk 26 and the second fixed disk 27 are pushed to slide in the inner cavity of the adjustment cylinder 16 and approach each other, thereby increasing the bearing capacity of the first sealing cover 17 and the second sealing cover 18. When the raw material falls on the first sealing cover 17 and the second sealing cover 18 to a certain extent, the first sealing cover 17 and the second sealing cover 18 cannot withstand the weight of the raw material and drive the rotating rod 19 to flip, thereby opening the collecting cylinder 21 to discharge the raw material into the calender, thereby improving the discharge accuracy of the raw material, ensuring that the raw material discharged into the calender can be completely melted, and improving the quality of the PVC film.

[0028] like Figures 2 to 4As shown, the first fixed disk 26 is fixedly connected to the second fixed column 29 at one end away from the threaded sleeve 25, and the second fixed disk 27 is fixedly connected to the first fixed column 28 at one end away from the threaded sleeve 25. There are two first fixed columns 28 and two second fixed columns 29, which are symmetrically arranged. Insert columns 30 are inserted into the inner cavities of the first fixed columns 28 and the second fixed columns 29, and torsion springs 32 are fixedly connected to both walls of the inner cavity of the adjusting cylinder 16. The first fixed disk 26 is fixedly connected to the torsion spring 32 at one end away from the second fixed column 29, and the second fixed disk 27 is fixedly connected to the torsion spring 32 at one end away from the first fixed column 28.

[0029] Specifically, when the discharge amount of the raw material needs to be adjusted, the knob 23 is driven to rotate, and the knob 23 drives the threaded rod 24 to rotate, and then the threaded rod 24 is threaded to drive the threaded sleeve 25 to move, and when the threaded sleeve 25 moves away from each other in the inner cavity of the adjusting cylinder 16, the first fixed disk 26 and the second fixed disk 27 are pulled to slide and move away from each other in the inner cavity of the adjusting cylinder 16, and at the same time, the first fixed disk 26 and the second fixed disk 27 squeeze the torsion spring 32 on the two walls of the inner cavity of the adjusting cylinder 16 to increase the torsion of the torsion spring 32, and the first fixed disk 26 and the second fixed disk 27 will also drive the first fixed column 28 and the second fixed column 29 to move away from each other, and at the same time, the plug column 30 slides on the first fixed column 28 and the second fixed column 29, so that during the flipping process of the rotating rod 19, the traction rope 31 can be pulled to drive the plug column 30 to rotate, and the plug column 30 can drive the first fixed column 28 and the second fixed column 29 to rotate, and at the same time, the first fixed column 28 and the second fixed column 29 drive the first fixed plate 26 and the second fixed plate 27 to rotate, and the first fixed plate 26 and the second fixed plate 27 will drive the threaded sleeve 25 to rotate, and then drive the threaded rod 24 to rotate inside the U-shaped fixing frame 15, and at the same time, the first fixed plate 26 and the second fixed plate 27 twist the torsion spring 32, so that the rotating rod 19 opens the first sealing cover 17 and the second sealing cover 18 to discharge the raw material during the flipping process, thereby realizing the adjustment of the quantitative discharge of the raw material.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a wire arrangement hole 22 is provided at one end of the adjusting cylinder 16 close to the rotating rod 19 , and a traction rope 31 passes through the wire arrangement hole 22 and is fixedly connected to the plug column 30 , and an ear hanger 2 is fixedly connected to the outside of the storage tank 1 .

[0031] Specifically, when the PVC film is processed and produced, the storage tank 1 is lifted by the ear hanger 2 through an external crane, and the storage tank 1 is installed above the melting port of the calender using the mounting seat 12, and is fixed to the calender by passing through the mounting hole 14 with an external bolt. When discharging the raw material, the rotating rod 19 pulls the traction rope 31 out of the inner cavity of the wire arrangement hole 22 during the flipping process, and the first sealing cover 17 and the second sealing cover 18 are opened to discharge the raw material, thereby realizing the adjustment of the quantitative discharge of the raw material. Embodiment 2

[0032] like Figures 1 to 7 As shown in Comparative Example 1, another embodiment of the present invention is: like Figure 1 , Figure 2 and Figure 7 As shown, a connecting pipe 4 is fixedly connected to the outside of the storage tank 1, and the connecting pipe 4 is arranged in an inclined shape. The connecting pipe 4 is fixedly connected to the loading barrel 3 at one end away from the storage tank 1, and a fixed pipe 10 is fixedly connected to the outside of the loading barrel 3. The fixed pipe 10 is fixedly connected to a funnel 11 at one end away from the loading barrel 3.

[0033] Specifically, after the storage tank 1 and the calender are installed and fixed, the raw materials for PVC film production are poured into the inner cavity of the funnel 11, and the funnel 11 is used to guide the raw materials into the fixed tube 10 and fall into the inner cavity of the loading barrel 3, and then the raw materials in the inner cavity of the loading barrel 3 are driven to be transported upward. When transported to the top, the raw materials will fall into the inner cavity of the connecting pipe 4, and at the same time, the raw materials will be discharged into the storage tank 1 through the connecting pipe 4 for storage, avoiding the trouble of transporting the raw materials to the calender when the PVC film needs to be processed, and using the feeding device to feed the calender.

[0034] like Figure 1 , Figure 3 and Figure 7 As shown, the inner cavity of the loading barrel 3 is rotatably connected to a conveying auger 41, the upper end of the conveying auger 41 passes through the loading barrel 3 and is fixedly connected to a first pulley 5, the external side of the first pulley 5 is connected to a toothed belt 9, and the end of the toothed belt 9 away from the first pulley 5 is connected to a second pulley 8.

[0035] Specifically, after the storage tank 1 and the calender are installed and fixed, the raw materials for PVC film production are poured into the inner cavity of the funnel 11, and the funnel 11 is used to guide the raw materials into the fixed tube 10 and fall into the inner cavity of the loading barrel 3, and then the second pulley 8 is driven to rotate, and at the same time, the second pulley 8 drives the toothed belt 9 to rotate, and then drives the first pulley 5 to rotate, and then the first pulley 5 drives the conveying auger 41 to rotate, and then during the rotation of the conveying auger 41, the raw materials in the inner cavity of the loading barrel 3 can be twisted and transported upward, and when the raw materials are transported to the top of the inner cavity of the loading barrel 3, they will be introduced into the inner cavity of the storage tank 1 through the inclined connecting pipe 4 for storage, and when the PVC film needs to be manufactured and processed, the raw materials are directly discharged into the calender for processing by opening the storage tank 1, thereby solving the trouble that the automatic feeding device of the PVC film calender cannot collect and store the raw materials for PVC film production when the calender is not working.

[0036] like Figure 1 , Figure 3 and Figure 5As shown, a fixing frame 6 is fixedly connected to the upper end of the storage tank 1, a driving motor 7 is installed on the upper end of the fixing frame 6, the driving motor 7 is fixedly connected to the second pulley 8 through an output shaft, a transmission shaft 33 is fixedly connected to the lower end of the second pulley 8, and an anti-blocking unloading component is arranged outside the transmission shaft 33.

[0037] Specifically, during the raw material discharge process, the second pulley 8 is driven to rotate by the output shaft of the driving motor 7, and at the same time, the second pulley 8 drives the transmission shaft 33 to rotate, and then the transmission shaft 33 drives the anti-blocking discharge component to work, thereby preventing the raw materials from being blocked at the discharge port 40 of the storage tank 1 when the storage tank 1 discharges the raw materials into the calender.

[0038] like Figure 1 , Figure 3 and Figure 5 As shown, the anti-blocking unloading component includes a V-shaped stirring frame 34 fixedly connected to the outside of the transmission shaft 33, a slide groove 35 is arranged inside the V-shaped stirring frame 34, a spring 36 is fixedly connected to the bottom of the inner cavity of the slide groove 35, a T-shaped stirring rod 37 is fixedly connected to one end of the spring 36 away from the bottom of the inner cavity of the slide groove 35, and a flip rod 38 is fixedly connected to the end of the T-shaped stirring rod 37 away from the spring 36.

[0039] Specifically, in the process of discharging raw materials, the second pulley 8 is driven to rotate by the output shaft of the driving motor 7, and the second pulley 8 drives the transmission shaft 33 to rotate, and then the transmission shaft 33 drives the V-shaped stirring frame 34 to rotate. During the rotation of the V-shaped stirring frame 34, the spring 36 in the inner cavity of the slide groove 35 bounces the T-shaped stirring rod 37 to move, and the T-shaped stirring rod 37 pushes the flipping rod 38 to move and fits with the inner cavity wall of the storage tank 1, so that during the rotation of the V-shaped stirring frame 34, the raw materials in the inner cavity of the storage tank 1 can be flipped to avoid the accumulation of raw materials at the bottom of the inner cavity of the storage tank 1, causing blockage when the raw materials are discharged. In addition, the raw materials for PVC film production have several different auxiliary materials, so that during the rotation of the V-shaped stirring frame 34, the raw materials can also be stirred and mixed, thereby solving the problem that the automatic feeding device of the existing PVC film calender cannot stir and flip the raw materials when discharging raw materials into the calender in a quantitative manner, resulting in blockage of the raw materials at the discharge port of the calender.

[0040] like Figure 1 , Figure 5 and Figure 7 As shown, a rotating block 39 is fixedly connected to the lower end of the transmission shaft 33, and the rotating block 39 intermittently opens the discharge port 40 during the rotation process. A stirring mechanism is arranged outside the transmission shaft 33, and the stirring mechanism is an existing mixing stirring mechanism.

[0041] Specifically, during the discharge of raw materials, the transmission shaft 33 is driven to rotate, and then the transmission shaft 33 drives the rotating block 39 to rotate. During the rotation of the rotating block 39, the discharge port 40 can be opened intermittently, and at the same time, the raw materials in the inner cavity of the storage tank 1 fall into the inner cavity of the collecting cylinder 21 through the discharge port 40 for storage. In addition, during the rotation of the rotating block 39, the raw materials at the bottom of the inner cavity of the storage tank 1 can be stirred to avoid the blockage of the discharge port 40 by the raw materials, thereby achieving quantitative discharge of the raw materials, avoiding the blockage of the calender discharge port by too fast discharge of the raw materials, and ensuring the efficiency of the raw materials entering the calender for melting.

[0042] Working principle: when processing and producing PVC film, the storage tank 1 is installed above the melting port of the calender by using the mounting seat 12, and is fixed to the calender by penetrating the mounting hole 14 with an external bolt, and then the raw material in the inner cavity of the storage tank 1 falls into the inner cavity of the collecting cylinder 21 through the discharge port 40, and the lower end of the inner cavity of the collecting cylinder 21 is provided with a first sealing cover 17 and a second sealing cover 18, so that the raw material is stored in the inner cavity of the collecting cylinder 21. After storing a certain amount of raw material, the first sealing cover 17 and the second sealing cover 18 cannot withstand the weight of the raw material, driving the rotating rod 19 to flip in the inner cavity of the U-shaped fixing block 20, thereby opening the collecting cylinder 21 to discharge the raw material in the inner cavity, and then the raw material falls into the melting port of the calender for melting. When the discharge amount of the raw material needs to be adjusted, the driving knob 23 is rotated, and the knob 23 drives the threaded rod 24 to rotate, and then the threaded rod 24 threadedly drives the threaded sleeve 25 to move, and when the threaded sleeve 25 moves away from each other in the inner cavity of the adjusting cylinder 16, the first fixed disk 26 and the second fixed disk 27 are pulled to slide and move away from each other in the inner cavity of the adjusting cylinder 16, and at the same time, the first fixed disk 26 and the second fixed disk 27 squeeze the torsion spring 32 on the two walls of the inner cavity of the adjusting cylinder 16 to increase the torsion of the torsion spring 32, and the first fixed disk 26 and the second fixed disk 27 will also drive the first fixed column 28 and the second fixed column 29 to move away from each other, and at the same time, the plug column 30 slides on the first fixed column 28 and the second fixed column 29, so that during the turning process of the rotating rod 19, the traction rope 31 can be pulled to drive the plug column 30 to rotate, and the plug column 30 can drive the first fixed column 28 and the second fixed column 29 to rotate, and at the same time, the first fixed column 28 and the second fixed column 29 can drive the first fixed plate 26 and the second fixed plate 27 to rotate, and the first fixed plate 26 and the second fixed plate 27 can drive the threaded sleeve 25 to rotate, and then drive the threaded rod 24 to rotate inside the U-shaped fixing frame 15, and at the same time, the first fixed plate 26 and the second fixed plate 27 twist the torsion spring 32, so that the rotating rod 19 opens the first sealing cover 17 and the second sealing cover 18 to discharge the raw material during the turning process, thereby realizing the adjustment of the quantitative discharge of the raw material; In the process of discharging raw materials, the second pulley 8 is driven to rotate by the output shaft of the driving motor 7, and the second pulley 8 drives the transmission shaft 33 to rotate, and then the transmission shaft 33 drives the V-shaped stirring frame 34 to rotate. During the rotation of the V-shaped stirring frame 34, the spring 36 in the inner cavity of the slide groove 35 bounces the T-shaped stirring rod 37 to move, and the T-shaped stirring rod 37 pushes the flipping rod 38 to move and fits with the inner cavity wall of the storage tank 1. Therefore, during the rotation of the V-shaped stirring frame 34, the raw materials in the inner cavity of the storage tank 1 can be flipped to avoid the accumulation of raw materials at the bottom of the inner cavity of the storage tank 1, which causes blockage when the raw materials are discharged. In addition, the raw materials for producing PVC film have several different auxiliary materials, so during the rotation of the V-shaped stirring frame 34, the raw materials can also be stirred and mixed.
