Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco manufacturing, and in particular relates to a leaf shred loosening device for a leaf shred electronic scale blanking box. Background Art

[0002] At present, in the production of cigarettes, the cut leaves are conveyed to the metering tube by the belt conveyor and then fall onto the electronic scale belt. Then, the leaves fall from the belt conveyor to the vibrating conveyor trough below. The vibrating conveyor, through its reciprocating motion, sends the leaves into the tunnel-type rehumidification machine, where they exchange heat with steam to achieve expansion treatment.

[0003] Since the electronic scale adopts the constant flow control mode, it needs to maintain a certain height of leaf shreds reserve in the limiting tube to ensure the continuity and stability of the flow. However, affected by the flow control, the operation speed of the electronic scale is relatively slow. When the leaf shreds are piled up to a height of 300mm on the electronic scale belt, due to the thickness of the accumulation and the limitation of the belt speed, the leaf shreds are easy to form a pile during the falling process and fall into the trough of the vibrating conveyor.

[0004] It is worth noting that there is a height difference of 1000mm between the electronic scale belt and the vibrating conveyor trough, which limits the falling speed of the blades to a certain extent, making the supply of blades on the conveyor discontinuous and intermittent. This intermittent supply will cause the blades entering the rehumidifier to absorb uneven steam, which in turn affects their full expansion.

[0005] Ultimately, this uneven expansion will cause a large fluctuation in the moisture content at the outlet of the shredded tofu drying machine in the next process, reducing the filling value of the shredded tofu and seriously affecting the standard deviation and deviation pass rate of the outlet moisture content. This not only affects the overall quality of the product, but also makes it difficult to meet the requirements of homogeneous production. Utility Model Content

[0006] In order to solve the above-mentioned problems, the utility model designs a blade wire loosening device for a blade wire electronic weighing blanking box.

[0007] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0008] A blade wire loosening device for a blade wire electronic weighing blanking box comprises a blanking box, a shell is arranged on the side wall of the blanking box, a connecting cylinder is rotatably connected to the front and rear inner walls of the shell through a bearing, a connecting plate is arranged on the outer wall of the connecting cylinder, top plates are arranged on the front and rear outer walls of the connecting plate, and the right end of the connecting plate extends into the blanking box and is provided with a combing plate;

[0009] A rebound mechanism is provided between the front and rear sides of the inner bottom wall of the shell and the top plate, and a lifting mechanism is provided between the inner bottom wall of the shell and the connecting plate.

[0010] Furthermore, the rebound mechanism includes a cylinder, the bottom end of which is rotatably connected to the inner bottom wall of the shell through a pin shaft, a spring is provided on the inner bottom wall of the cylinder, a spring seat is provided at the top end of the spring, a round rod is provided on the top wall of the spring seat, the top end of the round rod extends out of the cylinder and is rotatably connected to the bottom of the top plate through a pin shaft.

[0011] Furthermore, the lifting mechanism includes a motor, the output end of the motor is locked with a rotating drum through a coupling, the rear end of the rotating drum is rotatably connected to a baffle through bearing 2, and the baffle is fixedly connected to the inner bottom wall of the shell, and a plurality of protrusions are interference fit connected to the outer wall of the rotating drum, and the protrusion at the top is in contact with the lower end surface of the top plate.

[0012] Furthermore, the outer ring of the second bearing is fixedly connected to the outer wall of the baffle through a bearing seat, and the inner ring of the second bearing is connected to the outer wall of the drum by interference fit.

[0013] Furthermore, the protrusions are arranged with gaps from front to back on the outer wall of the drum.

[0014] Furthermore, the combing plate is arranged at an angle, and the outer wall thereof is in a comb structure.

[0015] The beneficial effects of the utility model are:

[0016] Through the action of the loosening device, the clumped leaf filaments can be effectively loosened to make the leaf filaments more evenly distributed, which helps to improve the processing effect and quality stability of the leaf filaments in subsequent processes.

[0017] The loosening device is designed to ensure that the shreds are loosened with minimal breakage or damage, which helps maintain the integrity of the shreds, reduces unnecessary waste, and improves the final quality of the product.

[0018] The loosening device can improve the process of the blade from the electronic scale belt to the vibrating conveyor, making the blade fall more smoothly and reducing the pile phenomenon, which helps to ensure the continuous and uniform supply of blade on the vibrating conveyor, thereby improving the operating efficiency of the entire production line.

[0019] Since the loosening device can improve the distribution of the blade shreds on the vibrating conveyor, the blade shreds entering the rehumidifier can better exchange heat with the steam and absorb steam more evenly, which helps to achieve full expansion of the blade shreds and improve the stability of the moisture content at the outlet of the dryer in subsequent processes.

[0020] By installing a leaf shred loosening device, the entire shred-making process can be optimized, and the unevenness and fluctuations in the leaf shred processing process can be reduced, thereby improving the overall quality and consistency of cigarette products. This helps to meet the market demand for high-quality cigarettes and improve the market competitiveness of products. BRIEF DESCRIPTION OF THE DRAWINGS
