Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing, and more specifically, to an automatic feeding device for plastic masterbatch. Background Art

[0002] Masterbatch is a plastic colorant formed by well-dispersing a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant and good compatibility with the material to be colored. The carrier of the special masterbatch is the same as the plastic variety of the product and has good matching. After heating and melting, the pigment particles can be well dispersed in the product plastic; in the actual application process, before transportation, masterbatch is usually stored in a temporarily stored storage cylinder, which can store the masterbatch after pelletizing. Therefore, during the feeding process, it is necessary to open the discharge port at the bottom of the storage cylinder to discharge the masterbatch onto the conveyor belt for feeding. However, during discharging, since the discharge port cannot be controlled, the masterbatch falls too fast, and it is very easy to accumulate on the conveyor belt, and the discharging is very uneven.

[0003] Regarding the above problems and the technical problem of uneven discharging existing in the existing feeding device, after a large number of searches, an automatic feeding device for plastic masterbatch with a patent application number of 202322953715.6 was found. It relates to the technical field of masterbatch processing and includes a storage cylinder for storing masterbatch. A discharge box body for discharging is provided at the bottom of the storage cylinder; a conveying mechanism for feeding is arranged below the discharge box body; specifically, after the masterbatch is discharged through the discharge box body, it falls onto the conveying mechanism, and then the falling masterbatch can be conveyed out through the conveying mechanism; a sealing channel is opened in the discharge box body, and a sealing plate is slidably arranged in the sealing channel. Among them, a blanking through groove communicating with the storage cylinder is opened between the sealing plates, and the sealing plate is connected to a pushing mechanism that drives it to reciprocate in the sealing channel; when the blanking through groove is in a misaligned state with the storage cylinder, the sealing of the discharge box body is realized, and the masterbatch cannot fall, thereby avoiding the phenomenon of masterbatch falling and accumulating in the prior art, and the blanking is more uniform. However, the technical solution provided by this patent has the following problems:

[0004] However, when using this device, the motor drives the push rod to move, thereby driving the sealing plate to translate, so as to discharge the masterbatch. However, when the through groove of the sealing plate is discharging, the masterbatch still accumulates due to gravity drop, which leads to the masterbatch not being uniform enough on the conveyor belt, thereby affecting the feeding of the masterbatch.

[0005] The utility model can play a role in making the masterbatch more uniform during transportation. Summary of the Utility Model

[0027] The following is a combination of the appended examples of the present invention Figures 1-5 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0028] See also Figures 1-5, in the embodiment of the present utility model, an automatic feeding device for plastic masterbatch includes: a conveyor belt 1, a plurality of shielding groups 2 are arranged inside the conveyor belt 1, a limiting group 3 is arranged at the outlet of the conveyor belt 1, a guide plate 4 is nested at the outlet of the conveyor belt 1, baffles 101 are arranged on both sides of the conveyor belt 1, and a diversion port 102 is arranged on one side of the baffle 101; a diversion plate 5 is arranged outside the diversion port 102, and a limiting plate 103 is arranged at the bottom outside the diversion port 102. The diversion plate 5 includes a rotating rod 501 and a connecting plate 502. The connecting plate 502 is nested on the outer surface of the rotating rod 501, and the connecting plate 502 is movably connected to the rotating rod 501; the shielding group 2 includes two positioning blocks 201 and a positioning plate 202. The positioning plate 202 is nested inside the two positioning blocks 201, and the two positioning blocks 201 are fixedly installed on the inner side of the baffle 101 by bolts; the limiting group 3 includes a positioning rod 301, an adjusting plate 302 and an adjusting block 303. The adjusting plate 302 is nested on the outer surface of the positioning rod 301, and the adjusting block 303 is nested at the upper end of the positioning rod 301; the conveyor belt 1 is the core conveying component of the entire feeding device, responsible for carrying and transporting plastic masterbatch.By continuously operating, the masterbatch is conveyed from one end to the other end. There are multiple shielding groups 2 arranged inside, which are used to sort and regulate the conveyance of the masterbatch during the transportation process, preventing the masterbatch from being randomly piled up or offset on the conveyor belt 1. The baffles 101 are located on both sides of the conveyor belt 1, which play a role in preventing the masterbatch from falling off both sides of the conveyor belt 1, ensuring that the masterbatch is always within the effective conveyance range of the conveyor belt 1. There is a diversion port 102 arranged on one side, which is the channel for the masterbatch to be diverted. The two positioning blocks 201 are fixedly installed inside the baffle 101 by bolts, providing a support and fixing basis for the positioning plate 202. The setting of its position can be adjusted according to actual needs to adapt to different feeding requirements. During the transportation process, the positioning plate 202 can play a certain role in blocking and guiding the masterbatch, enabling the masterbatch to move more orderly on the conveyor belt 1, preventing stacking or blockage phenomena, and effectively preventing the masterbatch from piling up on the conveyor belt 1, making the masterbatch more evenly distributed on the conveyor belt 1. The diversion port 102 is arranged on one side of the baffle 101 and is the outlet for the masterbatch to be diverted from the conveyor belt 1. When it is necessary to divert the masterbatch to different positions or processes, the masterbatch leaves the conveyor belt 1 through the diversion port 102. There is a limit plate 103 arranged at the outer bottom. The limit plate 103 can limit the falling position and angle of the masterbatch at the diversion port 102, ensuring that the masterbatch can accurately enter the diversion plate 5 or the subsequent conveying channel; The connecting plate 502 is nested on the outer surface of the rotating rod 501 and is movably connected to the rotating rod 501, enabling the connecting plate 502 to rotate around the rotating rod 501, thereby adjusting the angle and position of the diversion plate 5. By adjusting the angle of the diversion plate 5, the diversion direction and flow rate of the masterbatch can be changed to meet different production process requirements; During the feeding process, the adjusting plate 302 can play a certain role in limiting and sorting the passing masterbatch, preventing the masterbatch from being chaotic or piled up at the outlet of the conveyor belt 1. By adjusting the position of the adjusting block 303, the distance and angle between the adjusting plate 302 and the outlet of the conveyor belt 1 can be precisely controlled, thereby realizing the precise control of the outflow rate and outflow direction of the masterbatch. The plate can guide the masterbatch flowing out of the outlet of the conveyor belt 1, enabling it to enter the subsequent process or equipment more smoothly, reducing the blockage and scattering phenomena of the masterbatch at the outlet of the conveyor belt 1, and making the device more stable during use.

[0029] The two positioning blocks 201 are in the shape of a "concave" character, and the positioning blocks 201 and the positioning plates 202 are movably connected. The upper ends of the two positioning blocks 201 are provided with grooves 203, and the grooves 203 pass through the two ends of the positioning blocks 201. Among them, a number of through holes 204 are penetrated on both sides of the positioning plates 202. Limit rods 205 are provided inside the through holes 204, and the limit rods 205 can be embedded in the grooves 203. The limit rods 205 and the through holes 204 are movably connected, and anti-slip sleeves are nested on the outer surfaces of the two ends of the limit rods 205; the two positioning blocks 201 are in the shape of a "concave" character, which provides better nesting and support for the positioning plates 202. The inner space of the "concave" character can accommodate the positioning plates 202, so that the positioning plates 202 can be stably installed between the two positioning blocks 201. At the same time, the "concave" shape design positions and restricts the positioning plates 202 during installation and use to prevent it from unnecessary The displacement or shaking of the positioning plate 202 is prevented by the movable connection, so that the positioning plate 202 can be moved or adjusted relative to the positioning block 201 to a certain extent, which increases the flexibility and adjustability of the entire device. When the limit rod 205 is embedded in the groove 203, the connection and fixation between the positioning plate 202 and the positioning block 201 can be achieved. By inserting the limit rod 205 into the grooves 203 at different positions, the position of the positioning plate 202 between the positioning blocks 201 can be adjusted to meet different working requirements, so that the device can be adjusted according to the masterbatch. The main function of the anti-slip sleeve is to increase friction to prevent the limit rod 205 from accidentally sliding or loosening during operation. When the limit rod 205 is inserted into the groove 203 and contacts the outside through the anti-slip sleeve, the anti-slip sleeve can improve the stability and reliability of the connection, ensuring that the positioning plate 202 will not change position due to vibration or other external forces during operation, making the device more stable when in use.

[0030] In the embodiment of the present utility model, the positioning rod 301 is in an "L" shape. One end of the positioning rod 301 is fixedly installed on the outside of the baffle 101. Among them, one side of the adjusting plate 302 is fixedly installed with a sleeve 304. The sleeve 304 is nested at the other end of the positioning rod 301. The sleeve 304 is movably connected to the positioning rod 301, and the positioning rod 301 can penetrate through both ends of the sleeve 304. One end of the positioning rod 301 can be used for fixed installation on the outside of the baffle 101, while the other end can be connected and cooperated with other components to achieve the support and positioning of other components. The baffle 101, as a part of the device, provides a solid support foundation for the positioning rod 301, enabling the positioning rod 301 to bear the forces and pressures from other components and ensuring the normal operation of the entire limit group 3. The sleeve 304 is an important component connected to the adjusting plate 302. By being fixedly installed on one side of the adjusting plate 302, the adjusting plate 302 and the sleeve 304 can move and adjust as a whole. The sleeve 304 can move relative to the positioning rod 301 to adjust the position of the adjusting plate 302. The sleeve 304 can slide or rotate along the positioning rod 301 to meet different working requirements. The distance between the adjusting plate 302 and the outlet of the conveyor belt 1 can be changed by adjusting the position of the sleeve 304 on the positioning rod 301, thereby controlling the outflow rate and outflow direction of the masterbatch. The sleeve 304 can be adjusted to different positions on the positioning rod 301 according to actual needs, increasing the flexibility and adjustability of the device. At the same time, it is also convenient to operate and adjust the sleeve 304 and the positioning rod 301 during installation and maintenance, making the device more flexible during use.

[0031] In the embodiment of the present utility model, a rotating shaft 401 is disposed through the inside of the guide plate 4. Nuts 402 are nested at both ends of the rotating shaft 401, and the nuts 402 are located at both ends of the conveyor belt. The rotating shaft 401 and the nuts 402 are threadedly arranged. The rotating shaft 401 plays a key supporting and rotating role in the guide plate 4. The design of penetrating the guide plate 4 enables the rotating shaft 401 to be stably installed in the guide plate 4, providing an axis for the movement or adjustment of the guide plate 4. The nuts 402 are mainly used to fix and adjust the position of the rotating shaft 401 in the entire device. By rotating the nuts 402, the position of the rotating shaft 401 can be precisely adjusted within a certain range. According to the conveying requirements of the masterbatch and the angle requirements of the guide plate 4, the position of the rotating shaft 401 can be finely adjusted, thereby changing the inclination angle or height of the guide plate 4. The threaded connection can provide a large frictional force, making the nuts 402 not easily loosen during the working process, ensuring the stable position of the rotating shaft 401, and thus ensuring that the guide plate 4 can stably guide the flow of the masterbatch. When it is necessary to maintain or replace the guide plate 4 or the rotating shaft 401, the threaded connection makes the disassembly and installation of the nuts 402 relatively easy, improving the work efficiency.

[0032] Working principle: The conveyor belt 1, as the core conveying component, starts to operate and conveys the plastic masterbatch from one end to the other end. Multiple shielding groups 2 inside the conveyor belt 1 play a role. Under the support and restriction of two positioning blocks 201, the positioning plate 202 blocks and guides the masterbatch. Since the positioning block 201 is in the shape of a "concave" character and is movably connected to the positioning plate 202, the positioning plate 202 can be adjusted to a certain extent according to actual needs. When the masterbatch moves on the conveyor belt 1, the positioning plate 202 prevents the masterbatch from being randomly stacked or offset, enabling it to be transported orderly on the conveyor belt 1, making the masterbatch more evenly distributed on the conveyor belt 1. The groove 203 at the upper end of the positioning block 201 and the limiting rods 205 in the through holes 204 on both sides of the positioning plate 202 cooperate with each other. By inserting the limiting rods 205 into the grooves 203 at different positions, the position of the positioning plate 202 can be adjusted to meet different feeding requirements. The anti-slip sleeves at both ends of the limiting rods 205 increase the friction force to prevent the limiting rods 205 from accidentally sliding, ensuring the stable operation of the positioning plate 202. As the masterbatch is transported, when shunting is required, the masterbatch reaches the shunt opening 102 on one side of the conveyor belt 1. The limiting plate 103 at the bottom outside the shunt opening 102 restricts the falling position and angle of the masterbatch at the shunt opening 102, ensuring that the masterbatch can accurately enter the shunt plate 5 or the subsequent conveying channel. The connecting plate 502 of the shunt plate 5 is nested on the outer surface of the rotating rod 501 and is movably connected. By rotating the connecting plate 502, the angle and position of the shunt plate 5 can be adjusted, and according to different production process requirements, the shunting direction and flow rate of the masterbatch can be changed. When the masterbatch reaches the outlet of the conveyor belt 1, the limiting group 3 starts to play a role. The adjusting plate 302 is nested on the outer surface of the positioning rod 301. Through the movable connection between the sleeve 304 and the positioning rod 301, it can move along the positioning rod 301 and adjust its position, playing a certain role in limiting and sorting the passing masterbatch, preventing the masterbatch from being chaotic or stacked at the outlet of the conveyor belt 1. The adjusting block 303 is nested on the upper end of the positioning rod 301. By adjusting the position of the adjusting block 303, the distance and angle between the adjusting plate 302 and the outlet of the conveyor belt 1 can be accurately controlled, thereby realizing the precise control of the outflow rate and outflow direction of the masterbatch. The guide plate 4 nested at the outlet of the conveyor belt 1 works under the support of the rotating shaft 401. Nuts 402 are nested at both ends of the rotating shaft 401. The nuts 402 are located at both ends of the conveyor belt and are threadedly connected to the rotating shaft 401. By rotating the nuts 402, according to the conveying requirements of the masterbatch and the angle requirements of the guide plate 4, the position of the rotating shaft 401 can be finely adjusted, thereby changing the inclination angle or height of the guide plate 4. The guide plate 4 guides the masterbatch flowing out of the outlet of the conveyor belt 1, enabling it to enter the subsequent processes or equipment more smoothly, reducing the blockage and scattering of the masterbatch at the outlet of the conveyor belt 1, and ensuring the stable progress of the entire feeding process.
