Description

Technical Field

[0001] This utility model relates to a weighing and packaging device for low-shrinkage cable insulation material. Background Technology

[0002] Weighing and packaging cable insulation materials is a crucial step in cable manufacturing, and its efficiency and accuracy directly affect production pace and product quality. Due to its unique material formulation and particle characteristics (such as high electrostatic adsorption and poor flowability), low-shrinkage cable insulation materials tend to have particles that easily adhere and accumulate in the discharge pipe during packaging due to static electricity or humidity, affecting packaging efficiency. Therefore, this invention proposes a weighing and packaging device for low-shrinkage cable insulation materials to solve the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a weighing and packaging device for low-shrinkage cable insulation material to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A weighing and packaging device for low-shrinkage cable insulation material includes a support frame, and a weighing hopper and a storage hopper are arranged sequentially from top to bottom within the support frame, with the weighing hopper disposed in the storage hopper;

[0006] The storage hopper is equipped with a discharge pipe, and a baffle plate is installed at the outlet of the discharge pipe. A disturbance spring is installed on the baffle plate, and the disturbance spring is connected to the inner wall of the discharge pipe and the baffle plate. A drive assembly is installed on the storage hopper, and the drive assembly is connected to the baffle plate, so that the baffle plate rises and falls at the outlet of the discharge pipe to block the flow, and drives the disturbance spring to shake inside the discharge pipe to accelerate the discharge.

[0007] As an improvement to the above technical solution, a guide hopper is provided on the support frame, and support columns are provided at both ends of the guide hopper, with the two sets of support columns connected to the support frame.

[0008] The guide hopper is located at the outlet of the discharge pipe.

[0009] As an improvement to the above technical solution, two sets of limiting plates are symmetrically arranged at the outlet of the discharge pipe;

[0010] The limiting plate is provided with a sliding groove, and the barrier plate is slidably disposed in two sets of sliding grooves.

[0011] As an improvement to the above technical solution, an elastic rod is provided between the two sets of limiting plates;

[0012] The surface of the barrier plate is uniformly provided with multiple sets of protrusions. The barrier plate moves up and down in the sliding groove, so that the multiple sets of protrusions contact the elastic rod respectively.

[0013] As an improvement to the above technical solution, the drive assembly includes a mounting plate, which is connected to the outer wall of the storage hopper;

[0014] A lifting cylinder is provided on the mounting plate, and a piston rod is provided on the lifting cylinder. The piston rod is connected to the baffle plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By controlling the baffle plate to rise and fall at the outlet of the discharge pipe through the drive component, combined with the linkage design of the disturbance spring, the disturbance spring is triggered to shake synchronously during the movement of the baffle plate, which creates continuous disturbance to the material in the pipe. This structure effectively solves the blockage problem caused by electrostatic adsorption or accumulation of low shrinkage insulating granules, and significantly improves the smoothness of discharge and packaging speed.

[0019] Through the coordinated action of the weighing hopper and storage hopper set at the top and bottom within the support frame, continuous weighing and automatic transfer of cable insulation material are achieved, ensuring weighing accuracy and material flow efficiency. After the weighing hopper completes quantitative weighing, the material is directly introduced into the storage hopper below, avoiding material loss or error accumulation in the intermediate links.

[0027] 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.

[0028] Example:

[0029] like Figure 1-6 As shown, this embodiment proposes a weighing and packaging device for low shrinkage cable insulation material, including a support frame 10. The support frame 10 is provided with a weighing hopper 30 and a storage hopper 20 arranged sequentially from top to bottom. The weighing hopper 30 is disposed in the storage hopper 20.

[0030] The storage hopper 20 is provided with a discharge pipe 21. A baffle plate 50 is provided at the outlet of the discharge pipe 21. A disturbance spring 70 is provided on the baffle plate 50. The disturbance spring 70 is connected to the inner wall of the discharge pipe 21 and the baffle plate 50. A drive assembly 60 is provided on the storage hopper 20. The drive assembly 60 is connected to the baffle plate 50, so that the baffle plate 50 rises and falls at the outlet of the discharge pipe 21 to block the flow, and drives the disturbance spring 70 to shake inside the discharge pipe 21 to accelerate the discharge.

[0031] In this embodiment, when packaging low-shrinkage cable insulation granules, a quantitative weighing is performed using a weighing hopper 30. The weighed granules are then introduced into a storage hopper 20, and the drive assembly 60 drives the baffle plate 50 to lift, opening the outlet of the discharge pipe 21. The granules are then packaged using storage containers such as ton bags. During the lifting and lowering of the baffle plate 50, the disturbance spring 70 is driven to sway in the discharge pipe 21, thereby agitating the granules and accelerating the discharge efficiency of the discharge pipe 21.

[0032] The baffle plate 50 is controlled to rise and fall at the outlet of the discharge pipe 21 by the drive component 60. Combined with the linkage design of the disturbance spring 70, the disturbance spring 70 is triggered to shake during the movement of the baffle plate 50, which creates a continuous disturbance to the material in the pipe. This structure effectively solves the blockage problem caused by electrostatic adsorption or accumulation of low shrinkage insulating granules, and significantly improves the smoothness of discharge and packaging speed.

[0033] Through the coordinated action of the weighing hopper 30 and the storage hopper 20 set at the top and bottom within the support frame 10, continuous weighing and automatic transfer of cable insulation material are achieved, ensuring weighing accuracy and material flow efficiency. After the weighing hopper 30 completes quantitative weighing, the material is directly introduced into the storage hopper 20 below, avoiding material loss or error accumulation in the intermediate links.

[0034] Specifically, the support frame 10 is provided with a guide hopper 40, and the two ends of the guide hopper 40 are provided with support columns 41, and the two sets of support columns 41 are connected to the support frame 10.

[0035] The guide hopper 40 is located at the outlet of the discharge pipe 21.

[0036] In this embodiment, a stable material guiding channel is formed by the guide hopper 40 and symmetrically distributed support columns 41 on the support frame 10, ensuring that the material at the outlet of the discharge pipe 21 falls into the ton bag or packaging container in a concentrated and orderly manner, effectively preventing the granular material from scattering or deviating from the target area, and reducing the risk of material waste and environmental pollution.

[0037] Specifically, two sets of limiting plates 23 are symmetrically arranged at the outlet of the discharge pipe 21;

[0038] The limiting plate 23 is provided with a sliding groove 22, and the barrier plate 50 is slidably disposed in two sets of sliding grooves 22.

[0039] In this embodiment, the symmetrically arranged limiting plate 23 and sliding groove 22 provide a two-point linear guiding constraint for the barrier plate 50, ensuring that the barrier plate 50 always maintains a vertical trajectory during the lifting process, avoiding skewness or jamming, thereby improving the accuracy and reliability of the barrier plate 50's movement. Moreover, the closed guiding structure formed by the limiting plate 23 and sliding groove 22 forms a tight contact surface with the outlet of the discharge pipe 21 when the barrier plate 50 descends, effectively preventing the granular material from leaking from the side gap and enhancing the sealing performance.

[0040] Specifically, an elastic rod 24 is provided between the two sets of limiting plates 23;

[0041] The surface of the barrier plate 50 is uniformly provided with multiple sets of protrusions 51. The barrier plate 50 moves up and down in the sliding groove 22, so that the multiple sets of protrusions 51 contact the elastic rod 24 respectively.

[0042] In this embodiment, the protrusions 51 evenly distributed on the surface of the barrier plate 50 periodically squeeze the elastic rod 24 during the lifting and lowering process, triggering the reciprocating deformation of the elastic rod 24. The high-frequency micro-vibration generated by this action is transmitted to the surface of the barrier plate 50, effectively shaking off the residual particles attached to the barrier plate 50 and the inner wall of the discharge pipe 21, realizing dynamic self-cleaning, avoiding sealing failure or jamming problems caused by material caking, and at the same time, the discharge efficiency of the discharge pipe 21 can also be improved through high-frequency micro-vibration.

[0043] Specifically, the drive assembly 60 includes a mounting plate 61, which is connected to the outer wall of the storage hopper 20;

[0044] A lifting cylinder 62 is provided on the mounting plate 61, and a piston rod 63 is provided on the lifting cylinder 62. The piston rod 63 is connected to the baffle plate 50.

[0045] Specifically, a connecting plate 52 is provided on the barrier plate 50, and the piston rod 63 is connected to the connecting plate 52 by bolts.

[0046] In this embodiment, the lifting cylinder 62 can effectively drive the connecting plate 52 to rise and fall, thereby effectively driving the barrier plate 50 to rise and fall.

[0047] Specifically, two sets of disturbance springs 70 are provided, and the two sets of disturbance springs 70 are symmetrically arranged between the baffle plate 50 and the inner wall of the discharge pipe 21.

[0048] 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.
