Description

Technical Field

[0001] The invention relates to the technical field of PVC raw material conveying, in particular to a feeding device for conveying PVC processing raw materials with a feeding sequence. Background Art

[0002] Raw material mixing is one of the most important processes in PVC processing. The order of adding the components of PVC is an important indicator of whether the mixing is ideal. Often, the defects of the products produced are caused by the improper order of adding materials during mixing.

[0003] The order of adding raw materials generally follows: PVC stabilizer should be added to the hot mixer at the same time (or about the same time) as the resin so that it can be evenly mixed with the resin as soon as possible. Plasticizer should be added before modifier, filler and external lubricant. Modifier is generally added in the late stage of high mixing when the material temperature is high and the viscosity is large. Filler should be added before or together with external lubricant. External lubricants such as wax should be added last when the material temperature is close to the discharge temperature. It can be seen that the order of PVC raw materials is more complicated to control.

[0004] However, most material conveying structures cannot realize the control of the material order and can only be operated manually, which brings about a more complicated workflow and reduces work efficiency. Summary of the invention

[0005] The invention discloses a feeding device for conveying PVC processing raw materials with a feeding sequence, aiming to solve the technical problem that most raw material conveying structures cannot realize the control of raw material sequence and can only be operated manually, thereby causing a more complicated work process and reducing work efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A feeding device for conveying PVC processing raw materials with a feeding sequence, comprising a feeding mechanism, the bottom end of the feeding mechanism is sequentially connected with a transition mechanism and a spiral conveying mechanism from top to bottom, and the feeding mechanism is fixed on a main bracket, the transition mechanism comprises a plurality of transition hoses, and the tops of the plurality of transition hoses are fixedly connected to the main bracket at equal intervals through fixing members, and the tops of the plurality of transition hoses pass through the main bracket at the same time;

[0008] The feeding mechanism includes a turntable, and the bottom end of the turntable is fixedly connected to a motor 1, and the motor 1 is fixedly connected to the main bracket. The turntable is divided into a plurality of stations, one of which is fixedly connected to a suction machine 1, and the other stations are respectively fixedly connected to conical transition pipes through bracket 2. A double-headed gas rod is fixedly connected to the outer wall of one side of the suction machine 1, and two output ends of the double-headed gas rod are respectively fixedly connected to sealing sleeves, and a plurality of conical transition pipes are respectively installed with guide fans;

[0009] The top outer wall of the main bracket is fixedly connected with a plurality of connecting pipes 1 through a bracket 1, and the two sealing sleeves can be simultaneously sleeved on the input end of the suction machine 1 and the outside of the connecting pipe 1, and can be simultaneously sleeved on the output end of the suction machine 1 and the outside of the transition hose, and the conical transition pipe can be attached to the top of the transition hose;

[0010] The top end of one of the transition hoses is connected to the output end of the second suction machine, and the second suction machine is fixedly connected to the top end of the main bracket, and the output end of the second suction machine and one end of a plurality of connecting pipes are respectively connected to an external suction pipe one;

[0011] The bottom end of the suction machine 1 is fixedly connected with the induction head 1, and the top outer wall of the main bracket is fixedly connected with the induction head 2, and the induction head 1 and the induction head 2 can sense each other, and the induction head 2 is located at the adjacent workstation of the suction machine 2.

[0012] A feeding mechanism is provided, which is mainly used for orderly feeding. The positions of the conical transition pipe and the suction machine 1 can be switched by the rotation of the motor 1. When the suction machine 1 contacts the top of any transition hose, the two sealing sleeves can complete the connection between the connecting pipe 1 and the transition hose. Under the action of the suction machine 1, the material extending from the entrance of the corresponding external suction pipe 1 can be adsorbed, and enters the transition mechanism and the spiral conveying mechanism accordingly. Therefore, orderly feeding can be completed by adjusting the operation law of the motor 1 and the connection of the external suction pipe. The setting of the suction machine 2 can make the corresponding external suction pipe 1 extend into the PVC stabilizer or resin, and make the external suction pipe 1 of the corresponding station of the induction head 2 extend into the other raw material of the PVC stabilizer and the resin. When the induction head 1 and the induction head 2 are inductively coupled to each other, the two materials can be pre-mixed. Under this structure, the device can complete the orderly feeding of multiple materials, and can simultaneously realize the single transportation and pre-mixing of materials, reduce the difficulty of manual operation, improve work efficiency, and optimize the material mixing effect.

[0013] In a preferred embodiment, the transition mechanism further comprises a transition main pipe and a bracket three, and a plurality of transition hoses are simultaneously connected to the inner wall of the transition main pipe, a feed port is fixedly connected to the inner wall of the bottom end of the transition main pipe, and the feed port is connected to the top end of the spiral conveying mechanism;

[0014] The bracket three is fixedly connected to the outer wall of the main bracket, and a gas rod one is installed on the bracket three, and a side outer wall of the bracket three is fixedly connected to a limited sleeve frame;

[0015] The limit sleeve is movably sleeved on the output rod of the gas rod, and one end of the output rod of the gas rod is hinged with two connecting rods, and the two connecting rods are symmetrically arranged. The outer ends of the two connecting rods are respectively fixedly connected with elastic plates through the connecting frame, and multiple rubber strips are equidistantly connected to the outer sides of the elastic plates.

[0016] A slider is movably sleeved on the outside of each connecting rod 1, and connecting rods 2 are hinged on the opposite sides of the two sliders, and the two connecting rods 2 are hinged on the outside of the limiting sleeve frame.

[0017] By setting up a transition mechanism, the raw materials are mainly transported from the transition main pipe and the feed port to the spiral conveying mechanism through multiple transition hoses for transmission. Since the transition hose is located at the tail end of the suction machine, it is less affected by the suction force than the front end of the suction machine, and the transition hose also needs to be transported to the spiral conveying mechanism. In order to avoid blockage in the transition hose caused by blockage at the feed port, the multiple transition hoses can be flapped by the operation of the gas rod to make the material fall smoothly. At the same time, the setting of multiple rubber strips can slightly wrap around the outside of the transition hose during the flapping process of the elastic plate. When the connecting rod is withdrawn, the transition hose will bend in the withdrawal direction to a certain extent. Based on the resilience of the transition hose, it can play a greater shaking effect. Used in conjunction with flapping, it can better ensure that the raw materials will not accumulate in the transition hose, thereby ensuring smooth transition and transportation of materials.

[0018] In a preferred embodiment, the spiral conveying mechanism comprises a conveying tube body, and one end of the conveying tube body is connected to a support rod 2 through a bearing frame, a cavity is provided on one side of the support rod 2, and the outer wall of the side is fixedly connected to a support rod 1 through a plurality of connecting frames 3 at the same time, a plurality of through slots 3 are equidistantly arranged in the cavity of the support rod 2, and a motor 2 is fixedly connected to the end of the support rod 1;

[0019] The inner wall of the support rod 1 is equidistantly provided with a plurality of through grooves 1 and slide grooves, and the plurality of through grooves 1 and slide grooves are staggered, and the outer side of the support rod 1 is movably sleeved with a sleeve, and the outer diameter of the sleeve is the same as the outer diameter of the support rod 2;

[0022] The outer wall of the sleeve is fixedly connected with a spiral blade 1, and one end of the sleeve is fixedly connected with a circular push plate, and the circular push plate is fitted to the inner wall of the conveying pipe body, the outer wall of the support rod 2 is fixedly connected with a spiral blade 2, and the spiral blade 1 and the spiral blade 2 can be combined into a whole, and the outer wall of one side of the support rod 1 is fixedly connected with a multi-section rod, and the output end of the multi-section rod is connected to the circular push plate.

[0023] By providing a spiral conveying mechanism, in the spiral conveying mechanism, when conveying a single material, the conveying can be completed by driving the entire spiral blade to rotate through the second motor; when the PVC stabilizer and the resin are transported synchronously, the sleeve is driven to retreat along the support rod one through the retraction of the multi-throttle rod, which can drive the distance between the two ends of each metal strip to decrease, thereby bending and extending between the two connecting frames three; at the same time, the spiral blade one and the spiral blade two are separated, and the material just falls between the two; as the second motor continues to run, the bent metal strip can be used as a stirring blade to stir and mix the material; as the material increases and stacks, it can continue to be conveyed until it contacts the second spiral blade; under this structure, pre-mixing during the conveying process can be achieved, so that the PVC stabilizer and the resin enter the hot mixer as synchronously as possible and are mixed evenly.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The present invention discloses a feeding device for conveying PVC processing raw materials with a feeding sequence, which is mainly used in the scene of conveying PVC raw materials.

[0039] Reference Figure 1-Figure 4 A feeding device for conveying PVC processing raw materials with a feeding sequence, comprising a feeding mechanism 1, the bottom end of the feeding mechanism 1 is sequentially connected with a transition mechanism 3 and a spiral conveying mechanism 4 from top to bottom, and the feeding mechanism 1 is fixed on a main support 2, the transition mechanism 3 comprises a plurality of transition hoses 301, and the tops of the plurality of transition hoses 301 are fixedly connected to the main support 2 at equal intervals through fixing members, and the tops of the plurality of transition hoses 301 pass through the main support 2 at the same time;

[0040] The feeding mechanism 1 includes a turntable 111, and a motor 110 is fixedly connected to the bottom end of the turntable 111, and the motor 110 is fixedly connected to the main bracket 2. The turntable 111 is evenly divided into a plurality of stations, one of which is fixedly connected to a suction machine 105, and the other stations are respectively fixedly connected to a conical transition pipe 112 through a bracket 2 114, and a double-headed gas rod 104 is fixedly connected to the outer wall of one side of the suction machine 105, and the two output ends of the double-headed gas rod 104 are respectively fixedly connected to a sealing sleeve 109, and a plurality of conical transition pipes 112 are respectively installed with a guide fan 113;

[0041] The top outer wall of the main support 2 is fixedly connected with a plurality of connecting pipes 102 through a support 103. Two sealing sleeves 109 can be simultaneously sleeved on the input end of the suction machine 105 and the outside of the connecting pipe 102, and can be simultaneously sleeved on the output end of the suction machine 105 and the outside of the transition hose 301. The conical transition pipe 112 can be attached to the top of the transition hose 301.

[0042] The top end of one of the transition hoses 301 is connected to the output end of the second suction machine 108, and the second suction machine 108 is fixedly connected to the top end of the main support 2, and the output end of the second suction machine 108 and one end of the plurality of connecting pipes 1 102 are respectively connected to the external suction pipe 1 101;

[0043] The bottom end of the suction machine 105 is fixedly connected with an induction head 106, and the top outer wall of the main bracket 2 is fixedly connected with an induction head 2 107, and the induction head 106 and the induction head 2 107 can sense each other. The induction head 2 107 is located at the adjacent station of the suction machine 2 108. The feeding mechanism 1 is mainly used for orderly feeding. The positions of the conical transition pipe 112 and the suction machine 105 can be switched by rotating the motor 110. When the suction machine 105 contacts the top of any transition hose 301, the two sealing sleeves 109 can be driven forward by the extension of the double-headed gas rod 104 to complete the connection between the connecting pipe 102 and the transition hose 301. Under the action of the suction machine 105, the material extending from the entrance of the corresponding external suction pipe 101 can be adsorbed and enter the transition mechanism 3 and the spiral conveying mechanism 4. Therefore, the orderly feeding can be completed by adjusting the operating law of the motor 110 and the connection of the external suction pipe 101. In addition, The guide fan 113 can move to between the connecting pipe 102 and the transition hose 301 after the transmission is released. The inlet area is expanded by the conical transition pipe 112, and the residual material dropped in the connecting pipe 102 can be guided to enter the transition hose 301 without causing excessive suction to transport the material. The setting of the suction machine 108 can make the corresponding external suction pipe 101 extend into the PVC stabilizer or resin, and make the external suction pipe 101 of the corresponding station of the induction head 107 extend into the other raw material of the PVC stabilizer and the resin. When the induction head 106 and the induction head 107 sense each other, the suction machine 108 is started to synchronously suck the material with the suction machine 105 to achieve pre-mixing of the two materials during the conveying process. Under this structure, the device can complete the orderly feeding of multiple materials, and can simultaneously realize the single transportation and pre-mixing of materials, reduce the difficulty of manual operation, improve work efficiency, and optimize the material mixing effect.

[0044] Reference Figure 4-Figure 5 In a preferred embodiment, the transition mechanism 3 also includes a transition main pipe 306 and a bracket three 302, and multiple transition hoses 301 are simultaneously connected to the inner wall of the transition main pipe 306, the bottom inner wall of the transition main pipe 306 is fixedly connected with a feed port 305, and the feed port 305 is connected to the top of the spiral conveying mechanism 4.

[0045] Reference Figure 4-Figure 5 In a preferred embodiment, the bracket three 302 is fixedly connected to the outer wall of the main bracket 2, and a gas rod 1 309 is installed on the bracket three 302, and a limiting sleeve 312 is fixedly connected to the outer wall of one side of the bracket three 302.

[0046] Reference Figure 4-Figure 5In a preferred embodiment, the limiting sleeve 312 is movably sleeved on the output rod of the gas rod 309, and one end of the output rod of the gas rod 309 is hinged with two connecting rods 308 at the same time, and the two connecting rods 308 are symmetrically arranged, and the outer ends of the two connecting rods 308 are fixedly connected to the elastic plate 303 through the connecting frame 307, and multiple rubber strips 304 are equidistantly connected to the outer side of the elastic plate 303.

[0047] Reference Figure 4-Figure 5 In a preferred embodiment, each connecting rod 1 308 is movably sleeved with a slider 310, and the opposite sides of the two sliders 310 are hinged with connecting rods 2 311, and the two connecting rods 2 311 are hinged to the outside of the limiting sleeve 312. The transition mechanism 3 mainly transports the raw materials from the transition main pipe 306 and the feed port 305 to the spiral conveying mechanism 4 for transmission through multiple transition hoses 301. Since the transition hose 301 is located at the tail end of the suction machine, it is less affected by the suction force than the front end of the suction machine, and the transition hose 301 needs to be transported to the spiral conveying mechanism 4. In order to avoid blockage at the feed port 305 causing blockage in the transition hose 301, the multiple transition hoses 301 can be slapped by the operation of the gas rod 1 309 to allow the material to fall smoothly. Specifically, the limiting sleeve 312 is used to position one end of the two connecting rods 2 311 The reciprocating extension and retraction of the gas rod 1 309 can drive the movement of the slider 310 to change the angle of the connecting rod 2 311, so that the two connecting rods 1 308 can reciprocate and hit the outer surfaces of the multiple transition hoses 301. Furthermore, the elastic plate 303 can expand the hitting area and provide a certain buffering force. The setting of the multiple rubber strips 304 can slightly wrap around the outside of the transition hose 301 under the action of inertia when the elastic plate 303 hits the surface of the transition hose 301. When the connecting rod 1 308 withdraws, the rubber strip 304 withdraws synchronously, and the withdrawal process will involve the transition hose 301 to bend in the withdrawal direction to a certain extent. Based on the resilience of the transition hose 301, it can play a more significant shaking effect. Used in conjunction with the slapping, it can better ensure that the raw materials will not be accumulated in the transition hose 301, and ensure the smooth transition and transportation of materials.

[0048] Reference Figure 6-Figure 8 In a preferred embodiment, the spiral conveying mechanism 4 includes a conveying tube body 401, and one end of the conveying tube body 401 is connected to a support rod 418 through a bearing frame 408, a cavity is provided on one side of the support rod 418, and the outer wall of the side is fixedly connected to a support rod 404 through multiple connecting frames 419 at the same time, and multiple through grooves 420 are equidistantly arranged in the cavity of the support rod 418, and the end of the support rod 404 is fixedly connected to a motor 402.

[0049] Reference Figure 6-Figure 8In a preferred embodiment, the inner wall of the support rod 404 is equidistantly provided with a plurality of through grooves 410 and slide grooves 409, and the plurality of through grooves 410 and slide grooves 409 are staggered, and a sleeve 414 is movably sleeved on the outside of the support rod 404, and the outer diameter of the sleeve 414 is the same as the outer diameter of the support rod 2 418.

[0050] Reference Figure 6-Figure 8 In a preferred embodiment, a cavity is also provided in the sleeve 414, and a plurality of slides 413 are evenly distributed in the cavity, and the slides 413 are correspondingly movably connected in the slide groove 409, and the inner wall of the sleeve 414 is fixedly connected with the inner support rod 411 through a plurality of connecting frames 412, and the plurality of connecting frames 412 correspondingly pass through a plurality of through grooves 410, and the inner support rod 411 is located in the cavity of the sleeve 414.

[0051] Reference Figure 6-Figure 8 In a preferred embodiment, one end of the inner support rod 411 is fixedly connected with a plurality of metal strips 415 at equal intervals, and the other ends of the plurality of metal strips 415 are fixedly connected with one end of the support rod 1 404 at equal intervals, and each metal strip 415 can pass through between adjacent connecting frames 3 419, and a circular support plate 416 is fixedly connected to an outer wall of one side of the metal strip 415, and a plurality of through grooves 417 are equidistantly arranged on the outer wall of the circular support plate 416, and the outer periphery of the circular support plate 416 is attached to the inner walls of the plurality of connecting frames 3 419, and the plurality of connecting frames 3 419 and the metal strip 415 pass through the plurality of through grooves 417.

[0052] Reference Figure 6-Figure 8In a preferred embodiment, the outer wall of the sleeve 414 is fixedly connected with a spiral blade 1 406, and one end of the sleeve 414 is fixedly connected with a circular push plate 405, and the circular push plate 405 is attached to the inner wall of the conveying pipe body 401, and the outer wall of the support rod 2 418 is fixedly connected with a spiral blade 2 407, and the spiral blade 1 406 and the spiral blade 2 407 can be combined into a whole, and the outer wall of one side of the support rod 1 404 is fixedly connected with a multi-throttle rod 403, and the output end of the multi-throttle rod 403 is connected to the circular push plate 405, and the spiral In the conveying mechanism 4, when conveying a single material, the conveying can be completed by driving the whole spiral blade to rotate through the motor 2 402. When the PVC stabilizer and the resin are transported synchronously, the sleeve 414 is driven to retreat along the support rod 1 404 through the retraction of the multi-throttle rod 403, and the inner support rod 411 is driven to retreat synchronously. The movement of the inner support rod 411 drives the distance between the two ends of each metal strip 415 to decrease, thereby bending and extending between the two connecting frames 3 419, and at the same time the spiral blade 1 406 and the spiral blade 2 407 are separated. The material just falls between the two. With the continuous operation of the motor 2 402, the bent metal strip 415 can be used as a stirring blade to stir and mix the material. As the material increases and stacks, it can continue to be transported until it contacts the spiral blade 2 407. This structure can achieve pre-mixing during the transportation process, so that the PVC stabilizer and the resin enter the hot mixer as synchronously as possible and are mixed evenly, so that the PVC stabilizer can play a better role. Then, with the extension of the multi-section rod 403, the entire spiral blade can be driven During the merging process, the circular support plate 416 can push the material that enters between the support rod 2 418 and the support rod 1 404 during the mixing process, and discharge it from the through groove 3 420 under the action of centrifugal force, and simultaneously play a partitioning role, reducing the space that the material can enter, making it easier to throw the material out, and at the same time, it can also press on the middle section of the metal strip 415 to ensure that the metal strip 415 can be stably bent outward. Correspondingly, the circular push plate 405 can also play a partitioning role, effectively preventing powder materials from affecting the operation of the multi-throttle rod 403.

[0053] Working principle: The feeding mechanism 1 is mainly used for orderly feeding. The positions of the conical transition pipe 112 and the suction machine 105 can be switched by rotating the motor 110. When the suction machine 105 contacts the top of any transition hose 301, the two sealing sleeves 109 can be driven forward by the extension of the double-headed gas rod 104 to complete the connection between the connecting pipe 102 and the transition hose 301. Under the action of the suction machine 105, the material extending from the entrance of the corresponding external suction pipe 101 can be adsorbed and enter the transition mechanism 3 and the spiral conveying mechanism 4. Thus, orderly feeding can be completed by adjusting the operating law of the motor 110 and the connection of the external suction pipe 101. In addition, the guide fan 113 can move between the connecting pipe 102 and the transition hose 301 after releasing the transmission, and pass through the conical transition pipe 1 12 enlarges the inlet area and can guide the residual materials dropped in the connecting pipe 102 to enter the transition hose 301 without causing excessive suction to transport the materials. The setting of the suction machine 108 can make the corresponding external suction pipe 101 extend into the PVC stabilizer or resin, and make the external suction pipe 101 of the corresponding station of the induction head 107 extend into the other raw material of the PVC stabilizer and the resin. When the induction head 106 and the induction head 107 sense each other, the suction machine 108 is started to synchronously suck the material with the suction machine 105 to realize the pre-mixing of the two materials during the conveying process. Under this structure, the device can complete the orderly feeding of multiple materials, and can simultaneously realize the single transportation and pre-mixing of materials, reduce the difficulty of manual operation, improve work efficiency, and optimize the material mixing effect.
