Description

Technical Field

[0001] This utility model relates to a device for quantitative injection of differentiated fiber masterbatch. Background Technology

[0002] In the fields of fiber masterbatch production and differentiated fiber preparation, the weighing accuracy of the quantitative injection device directly affects product quality and process stability. Existing quantitative injection devices generally use a weighing sensor installed on the hopper for weighing.

[0003] However, traditional quantitative injection devices mostly adopt a fixed weighing sensor layout, with the hopper rigidly installed on a preset base. In actual production, due to the general level deviation of the equipment installation base in the workshop, and the difference in foundation settlement between different production line conditions, multiple sets of weighing sensors are subjected to uneven loads. Some sensors are in an over-range or low-sensitivity working state for a long time, which will affect the service life of the weighing sensors. In view of this, this utility model proposes a differentiated fiber masterbatch quantitative injection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a differentiated fiber masterbatch quantitative injection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A differential fiber masterbatch quantitative injection device includes a hopper body, the hopper body is provided with a feed inlet, and two sets of connecting plates are provided at the feed inlet;

[0007] The connecting plate is provided with two sets of movable plates, and a weighing sensor is provided at the bottom of the movable plate. The connecting plate is provided with two sets of driving components, which cooperate with the two sets of movable plates respectively, so that the movable plates can be adjusted along the long side of the connecting plate.

[0008] As an improvement to the above technical solution, the hopper body is provided with a discharge port, and a slidingly connected sealing plate is provided at the discharge port.

[0009] As an improvement to the above technical solution, the hopper body is provided with an observation glass window;

[0010] The hopper body is provided with a disturbance pipe, which is matched with the outlet and is connected to the inner cavity of the hopper body.

[0011] As an improvement to the above technical solution, two sets of drive slots are symmetrically provided on the connecting plate;

[0012] The driving assembly includes a driving screw, which is rotatably disposed in a driving groove. A moving block is provided on the moving plate, which is slidably disposed in the driving groove. A threaded hole is provided on the moving block, and the driving screw is threadedly disposed in the threaded hole.

[0013] As an improvement to the above technical solution, a limiting block is also provided in the drive groove, and the limiting block is slidably disposed in the drive groove;

[0014] The limiting block is provided with a limiting hole, and the driving screw is rotatably disposed in the limiting hole.

[0015] As an improvement to the above technical solution, the cross-sections of the drive groove, the moving block, and the limiting block are all T-shaped;

[0016] The end face of the drive screw has an internal hexagonal hole.

[0017] As an improvement to the above technical solution, the connecting plate is provided with two sets of connecting and fixing holes, and the limiting block is provided with limiting and fixing holes. The limiting and fixing holes are connected to one set of connecting and fixing holes by bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By driving the moving plate to make linear displacement adjustment along the long side of the connecting plate through the drive component, the weighing sensor can achieve multi-degree-of-freedom precise positioning on the mounting plane. This structure breaks through the limitations of the traditional fixed weighing layout and effectively solves the problem of uneven force on the weighing sensor caused by uneven mounting base of the hopper body or differences in on-site working conditions, significantly improving the adaptability and measurement accuracy of the weighing system.

[0020] By independently adjusting the positions of the two sets of moving plates through two symmetrically arranged drive components, the spatial distribution of the four sets of weighing sensors can be adjusted in a coordinated manner. This design enables the weighing sensor group to adaptively form the optimal support posture according to the actual center of gravity distribution of the hopper, ensuring that the weighing load is evenly transmitted to each sensor, fundamentally eliminating off-center loading errors, and improving the consistency and reliability of quantitative measurement.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] like Figure 1-3 As shown, this embodiment proposes a differential fiber masterbatch quantitative injection device, including a hopper body (10), the hopper body (10) is provided with a feed inlet 11, and two sets of connecting plates 20 are provided at the feed inlet 11;

[0031] The connecting plate 20 is provided with two sets of movable plates 40. The bottom end of the movable plate 40 is provided with a weighing sensor 50. The connecting plate 20 is provided with two sets of driving components 60. The two sets of driving components 60 cooperate with the two sets of movable plates 40 respectively, so that the movable plates 40 can be adjusted along the long side of the connecting plate 20.

[0032] In this case, the specific structure of the weighing sensor 50 can be found in a silo weighing sensor disclosed in announcement number CN217424526U, and will not be described in detail here.

[0033] In this embodiment, when injecting the differentiated fiber masterbatch, the hopper body 10 is installed according to the actual situation. The driving component 60 drives the moving plate 40 to move along the long side of the connecting plate 20, which in turn drives the weighing sensor 50 to move until the four sets of weighing sensors 50 are adjusted to the actual installation position.

[0034] By driving the moving plate 40 to linearly adjust the displacement along the long side of the connecting plate 20 through the drive component 60, the weighing sensor 50 can achieve multi-degree-of-freedom precise positioning on the mounting plane. This structure breaks through the limitations of the traditional fixed weighing layout and effectively solves the problem of uneven force on the weighing sensor 50 caused by uneven mounting base of the hopper body 10 or differences in on-site working conditions, significantly improving the adaptability and measurement accuracy of the weighing system.

[0035] By independently adjusting the positions of the two sets of moving plates 40 through two symmetrically arranged drive components 60, the spatial distribution of the four sets of weighing sensors 50 can be adjusted in a coordinated manner. This design enables the weighing sensors 50 to adaptively form the optimal support posture according to the actual center of gravity distribution of the hopper, ensuring that the weighing load is evenly transmitted to each sensor, fundamentally eliminating off-center loading errors, and improving the consistency and reliability of quantitative measurement.

[0036] Specifically, the hopper body 10 is provided with a discharge port 12, and a slidably connected sealing plate 13 is provided at the discharge port 12.

[0037] In this embodiment, the sealing plate 13 is slidably disposed at the discharge port 12, which can effectively control whether material flows out of the discharge port 12.

[0038] Specifically, the hopper body 10 is provided with an observation glass window 14;

[0039] The hopper body 10 is provided with a disturbance pipe 15, which is matched with the outlet 12 and is connected to the inner cavity of the feed hopper body 10.

[0040] In this embodiment, the observation glass window 14 is integrated into the side wall of the hopper body 10 to form a non-intrusive material status monitoring channel. This structure breaks through the visual blind spot limitation of traditional closed hoppers, enabling operators to observe the material accumulation height, flow status and arching phenomenon inside the hopper in real time.

[0041] Of course, the disturbance pipe 15 is connected to an external air supply device, such as an air compressor, to form a self-excited airflow disturbance system. This system creates a dynamic airflow circulation in the discharge port 12 area, generating high-frequency micro-amplitude vibrations that act on the material accumulation, thus avoiding bridging and rat hole phenomena that are prone to occur at the discharge port 12, and ensuring continuous and stable discharge.

[0042] Specifically, two sets of drive slots 21 are symmetrically provided on the connecting plate 20;

[0043] The drive assembly 60 includes a drive screw 61, which is rotatably disposed in the drive groove 21. The movable plate 40 is provided with a movable block 41, which is slidably disposed in the drive groove 21. The movable block 41 is provided with a threaded hole 42, and the drive screw 61 is threadedly disposed in the threaded hole 42.

[0044] In this embodiment, when the movable plate 40 is displaced, the drive screw 61 is rotated. With the cooperation of the drive screw 61 and the threaded hole 42, the movable plate 40 can be displaced, thereby adjusting the position of the weighing sensor 50.

[0045] Specifically, a limiting block 30 is also provided in the drive groove 21, and the limiting block 30 is slidably disposed in the drive groove 21;

[0046] The limiting block 30 is provided with a limiting hole 31, and the driving screw 61 is rotatably disposed in the limiting hole 31.

[0047] In this embodiment, the limiting block 30 can support the drive screw 61 while preserving the circumferential rotational freedom of the screw, so as to avoid deformation due to excessive length of the drive screw 61.

[0048] Specifically, the cross-sections of the drive groove 21, the moving block 41, and the limiting block 30 are all T-shaped;

[0049] The end face of the drive screw 61 is provided with an internal hexagonal hole 62.

[0050] In this embodiment, the T-shaped cross-section of the drive groove 21, the moving block 41, and the limiting block 30 can generate a mechanical self-locking effect through geometric configuration, thereby improving the stability of the moving plate 40 and the limiting block 30.

[0051] Of course, the internal hexagonal hole 62 facilitates the rotation of the drive screw 61.

[0052] Specifically, the connecting plate 20 has two sets of connecting and fixing holes 22, and the limiting block 30 has a limiting and fixing hole 32. The limiting and fixing hole 32 and the set of connecting and fixing holes 22 are connected by bolts.

[0053] In this embodiment, the bolt connection between the connecting fixing hole 22 and the limiting fixing hole 32 can prevent the limiting block 30 from detaching from the drive groove 21.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
