Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, in particular to automatic metering and filling equipment for asphalt cold patch material. Background Art

[0002] Cold patch material is widely used as a key material in road repair. This material possesses unique physical properties, such as a certain degree of viscosity, susceptibility to agglomeration, and sensitivity to temperature fluctuations, which present numerous challenges during the packaging process. Prior art packaging of asphalt cold patch material typically involves manual operation or simple mechanical equipment. However, these traditional methods present several challenges that require urgent resolution. First, due to the viscosity of asphalt cold patch material, a "wake flow" phenomenon often occurs during the unloading process—where the material continues to flow even after being cut, resulting in a deviation between the actual loading amount and the preset value, seriously affecting product quality consistency. Second, the easy agglomeration of asphalt cold patch material makes the hopper, conveying system, and unloading device of traditional equipment prone to blockage, which not only reduces production efficiency but also increases the frequency and difficulty of equipment maintenance. Furthermore, existing packaging methods often rely on manual operation, which is labor-intensive and inefficient, making them difficult to meet the needs of large-scale production.

[0003] In response to the above problems, there is an urgent need for an automated equipment that can accurately measure and efficiently package asphalt cold patch materials. Summary of the Invention

[0004] The purpose of the present utility model is to provide an automatic metering and packaging equipment for asphalt cold patch material to solve the problems existing in the above-mentioned prior art. The equipment should be able to effectively solve the tail flow problem caused by the viscosity of the material, improve the metering accuracy, and have the characteristics of anti-clogging and easy cleaning, so as to meet the needs of the modern road maintenance industry for high-quality and high-efficiency asphalt cold patch material packaging.

[0005] To achieve the above purpose, the present invention provides the following solutions:

[0006] The utility model provides an automatic metering and packaging equipment for asphalt cold patch material, comprising a hopper, a support frame, a conveyor belt, a discharge gate, an electronic scale and a control electrical box; the hopper is arranged on the support frame; the feed end of the conveyor belt is located below the hopper, the discharge gate is provided below the discharge end of the conveyor belt, the electronic scale is located directly below the discharge gate, the electronic scale is used to hold a sealed barrel, and the sealed barrel is used to receive the asphalt cold patch material; the control electrical box is provided on the support frame, and the control module in the control electrical box is electrically connected to the conveyor belt, the discharge gate and the electronic scale respectively.

[0007] Optionally, a funnel is provided between the discharge end of the conveyor belt and the discharge gate.

[0009] Optionally, the percussion hammer is electrically connected to the control module.

[0010] Optionally, the unloading gate includes a pneumatic rod and a gate knife; the piston rod of the pneumatic rod is connected to one end of the gate knife.

[0011] Optionally, the unloading gate further includes a material blocking plate, which is arranged on a side of the upper surface of the gate knife close to the pneumatic rod.

[0012] Optionally, a probe is provided below the discharge end of the conveyor belt on one side of the sealing barrel, the probe is electrically connected to the control module, and the probe is used to detect whether a sealing barrel is placed on the electronic scale.

[0032] like Figures 1 to 4 As shown, this embodiment provides an automatic metering and packaging equipment for asphalt cold patch material, including a hopper 1, a support frame 2, a conveyor belt 4, a discharge gate 6, an electronic scale 8 and a control electrical box 11; the hopper 1 is arranged on the support frame 2; the feed end of the conveyor belt 4 is located below the hopper 1, and a discharge gate 6 is provided below the discharge end of the conveyor belt 4, and the electronic scale 8 is located directly below the discharge gate 6, and the electronic scale 8 is used to hold a sealed barrel 7, and the sealed barrel 7 is used to receive the asphalt cold patch material; a control electrical box 11 is provided on the support frame 2, and the control module in the control electrical box 11 is electrically connected to the conveyor belt 4, the discharge gate 6 and the electronic scale 8 respectively.

[0033] In this embodiment, a funnel 5 is provided between the discharge end of the conveyor belt 4 and the discharge gate 6 .

[0034] A jar 12 is mounted on the support frame 2 and located on the side of the hopper 1. This jar 12 is used to strike the hopper 1, dispersing any agglomerated material within. The jar 12 is electronically connected to the control module. If agglomerated material forms, the jar 12 is activated to disperse the material, ensuring continued normal operation of the equipment.

[0035] The unloading gate 6 includes a pneumatic rod 61, a material blocking plate 62, and a gate knife 63. The piston rod of the pneumatic rod 61 is connected to one end of the gate knife 63, and the material blocking plate 62 is arranged on the upper surface of the gate knife 63 near the side of the pneumatic rod 61. The material blocking plate 62 can prevent the asphalt cold patch material on the gate knife 63 from falling between the pneumatic rod 61 and the gate knife 63, thereby preventing the waste of asphalt cold patch material and ensuring the cleanliness of the equipment and the surrounding environment.

[0036] A probe is provided below the discharge end of the conveyor belt 4, on one side of the sealed barrel 7. The probe is electrically connected to the control module and is used to detect whether the sealed barrel 7 is placed on the electronic scale 8. In this embodiment, the probe is an infrared sensor probe 9. In other embodiments, other types of probes may also be used.

[0037] The conveyor belt 4 includes a conveyor motor 10 , which is electrically connected to the control module.

[0039] The specific operation process of the automatic metering and packaging equipment for asphalt cold patch material in this embodiment is as follows:

[0040] (1) Load the asphalt cold patch material into the hopper 1.

[0041] (2) The specified barrel filling mass is set by controlling the electrical box 11.

[0042] (3) When the infrared sensor probe 9 detects that the sealing barrel 7 is in place, the conveying motor 10 automatically starts to drive the conveyor belt 4 to rotate.

[0043] (4) At the same time, the air pressure rod 61 in the discharge gate 6 opens the gate knife 63, and the asphalt cold patch material falls into the sealed barrel 7 through the funnel 5.

[0044] (5) When the electronic scale 8 senses that the filling mass has reached the set value, the pneumatic rod 61 quickly closes the knife 63, accurately cutting off the material flow to prevent excessive material discharge.

[0045] (6) The conveying motor 10 stops automatically, completing one packing.

[0046] (7) Replace the new sealed barrel 7 and repeat the above process to achieve continuous automatic packaging.
