Description

Technical Field

[0001] This utility model relates to the field of biomass pellet technology, and in particular to a biomass pellet packaging machine. Background Technology

[0002] Biomass pellet fuel is primarily made from pure wood raw materials, containing no binders or additives. The wood chips are processed using specialized machinery and compressed into pellets to alter their density, strength, and combustion performance. This results in a high-density pellet, with the loose material becoming dense and seamless, thus limiting the rate of volatile organic compounds (VOCs) release and extending their combustion time. This ensures that most of the combustion reaction occurs only on the surface of the pellets. When the stove supply is sufficient, the loss of unburned VOC molecules is minimal, thereby reducing the production of black smoke.

[0003] When packaging existing biomass pellets, larger or irregularly shaped pellets need to be screened, which affects the bagging efficiency. At the same time, quantitative bagging is not possible during bagging, and subsequent weighing is required, which also affects the packaging efficiency. Therefore, this utility model provides a biomass pellet packaging machine. Utility Model Content

[0004] This utility model discloses a biomass pellet packaging machine, which aims to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A biomass pellet packaging machine includes a screening unit and a feeding unit: The screening unit includes a screening outer cylinder, with a first spring fixedly installed inside the outer cylinder. An L-shaped plate is fixedly installed at one end of the first spring, and a sieve disc is placed on top of the L-shaped plate. The detachable design of the L-shaped plate and the sieve disc facilitates the subsequent recycling of unqualified biomass pellets after screening. A slider is fixedly installed on top of the sieve disc. There are two L-shaped plates, with a rack fixedly installed on one side of the other L-shaped plate. A half-gear is meshed on the outer wall of the rack. The half-gear is a non-shaped gear with half teeth. A second spring is fixedly installed on one side of the rack. A limit plate is slidably fitted to the bottom of the L-shaped plate, providing a limiting effect and guiding the sliding of the L-shaped plate. A first motor output shaft is fixedly installed at the bottom of the half-gear, and the first motor provides power for the rotation of the half-gear. The feeding unit includes a feeding hopper, on which the bottom of the screening outer cylinder is fixedly installed. A conveying pipe is fixedly connected to the bottom of the feeding hopper, and a feeding pipe is fixedly connected to one end of the conveying pipe. A base is fixedly installed at the bottom of the feeding hopper. A threaded conveying rod is rotatably installed inside the conveying pipe. A second motor output shaft is fixedly installed at one end of the threaded conveying rod. The second motor provides rotational power to the threaded conveying rod, and the feeding amount can be controlled by limiting the number of rotations of the second motor.

[0006] In a preferred embodiment, according to the biomass pellet packaging machine of claim 1, a hook is fixedly installed at one end of the L-shaped plate, and the hook of the L-shaped plate is slidably inserted into the sieve disc, so that the sieve disc will not detach from the L-shaped plate under tension.

[0007] In a preferred embodiment, one end of the second spring is fixedly installed to the outer screening cylinder, and the limiting plate is fixedly installed on the inner circumference of the outer screening cylinder, thereby limiting and guiding the sliding of the L-shaped plate.

[0008] In a preferred embodiment, a ring is fixedly installed on the top of the slider. The slider is slidably installed on the top of the screening outer cylinder. The slider can be pulled upward by the ring to disengage from the screening outer cylinder, and the screen plate can be disengaged from the L-shaped plate, thus completing the disassembly of the screen plate. The slider guides the sliding of the screen plate and prevents the screen plate from falling downward under the action of gravity.

[0009] In a preferred embodiment, a mounting plate is fixedly installed on the bottom of the first motor. The mounting plate is fixedly installed on one side of the hopper to stabilize the position of the first motor and prevent the first motor from rotating during operation.

[0010] In a preferred embodiment, a rectangular through groove is provided inside the outer screening cylinder. The rack is slidably installed through the outer screening cylinder via the rectangular through groove. The rectangular through groove limits and guides the sliding of the rack. The teeth of the rack are thinner than the main body of the rack. The main body of the rack slides within the rectangular through groove, so the teeth of the rack do not contact the outer screening cylinder.

[0011] In a preferred embodiment, the second motor is fixedly installed at one end of the conveying pipe, and a support column is fixedly installed at the bottom of the conveying pipe. The support column is fixedly installed on the base, and the stability of the conveying pipe can be ensured by the support column.

[0012] As can be seen from the above, this utility model has the following technical effects: Firstly, the biomass pellets are placed into the sieve disc. Then, the first motor drives the half gear to rotate, which in turn drives the rack to move, thereby moving the sieve disc and stretching the first and second springs. When the half gear rotates to the gearless position, the second and first springs cause the sieve disc to rebound, thus realizing the back-and-forth movement of the sieve disc. Qualified biomass pellets are discharged from the through groove of the sieve disc. At this time, irregular or too coarse biomass pellets will be screened.

[0013] Secondly, the biomass pellets screened by the sieve disc enter the hopper. When the hopper is almost full, the second motor drives the threaded conveyor rod to rotate, thereby conveying the biomass pellets inside the conveyor pipe into the feeding pipe. The packaging bags are then manually placed at the bottom of the feeding pipe for bagging. The amount of biomass pellets conveyed can be controlled by adjusting the number of rotations of the second motor, allowing for preliminary quantitative measurement and ensuring that the amount of biomass pellets in the packaging bags is approximately consistent, thus improving packaging efficiency.

[0022] In this embodiment, biomass pellets are first placed into the sieve disc 104. Then, the first motor 110 drives the half gear 107 to rotate, and the half gear 107 drives the rack 106 to move, thereby moving the sieve disc 104 and stretching the first spring 102 and the second spring 108. When the half gear 107 rotates to the gearless position, the second spring 108 and the first spring 102 drive the sieve disc 104 to rebound, thereby realizing the back-and-forth movement of the sieve disc 104. Qualified biomass pellets are discharged from the through groove of the sieve disc 104. At this time, irregular or too coarse biomass pellets will be screened.

[0023] In a preferred embodiment, a hook is fixedly installed at one end of the L-shaped plate 103, and the hook of the L-shaped plate 103 is slidably inserted into the sieve plate 104; in this embodiment, the hook prevents the sieve plate 104 from detaching from the L-shaped plate 103 under tension.

[0024] In a preferred embodiment, one end of the second spring 108 is fixedly installed with the outer screening cylinder 101, and the limiting plate 109 is fixedly installed in the inner circumference of the outer screening cylinder 101; in this embodiment, the limiting plate 109 is used to limit and guide the sliding of the L-shaped plate 103.

In this embodiment, the rectangular through groove is used to limit and guide the sliding of the rack 106. The teeth of the rack 106 are thinner than the main body of the strip, and the main body of the strip slides in the rectangular through groove.

[0029] Working principle: When in use, biomass pellets are first placed into the sieve disc 104. Then, the first motor 110 drives the half gear 107 to rotate. The half gear 107 drives the rack 106 to move, thereby moving the sieve disc 104 and stretching the first spring 102 and the second spring 108. When the half gear 107 rotates to the gearless position, the second spring 108 and the first spring 102 drive the sieve disc 104 to rebound, thereby realizing the back-and-forth movement of the sieve disc 104. Under the back-and-forth movement, qualified biomass pellets are discharged from the through groove of the sieve disc 104. At this time, irregular or too coarse biomass pellets will be screened. During disassembly, the screen plate 104 is pulled upward by the pull ring at the top of the slider 105, so that the L-shaped plate 103 and the screen plate 104 are separated. During installation, the screen plate 104 is placed on top of the L-shaped plate 103, and the hook at one end of the L-shaped plate 103 is inserted into the screening groove of the screen plate 104 to complete the installation. This allows for the convenient recycling of biomass pellets screened inside the screen plate 104 and the convenient cleaning of biomass pellets stuck in the groove of the screen plate 104. Biomass sieved by screen 104 enters the hopper 201. When the hopper 201 is almost full, the second motor 205 drives the threaded conveyor rod 206 to rotate, thereby conveying the biomass pellets inside the conveyor pipe 202 into the feed pipe 203. The packaging bags are manually placed at the bottom of the feed pipe 203 for bagging. The amount of biomass pellets conveyed can be controlled by controlling the number of rotations of the second motor 205, which can initially measure the amount of biomass pellets in the packaging bags to ensure that the amount of biomass pellets in the packaging bags is approximately consistent.
