Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a powder and particle packaging machine suitable for different particle sizes. Background Technology

[0002] A powder or granule packaging machine is a mechanical device that automatically packages powdered or granular materials into individual packages according to a set weight or quantity. It is widely used in the food, pharmaceutical, and chemical industries. Through processes such as metering, filling, and sealing, it achieves precise packaging of materials, ensuring packaging efficiency and quality. Most existing equipment is suitable for materials of different particle sizes, capable of handling everything from micron-sized ultrafine powders to millimeter-sized granules, meeting the production needs of various scenarios and product categories.

[0003] However, in actual subcontracting work, two significant problems were found in the existing powder and granule subcontracting machines: In terms of bag compatibility, most existing devices lack a flexible bottom support structure, and the material directly impacts the bottom of the bag during filling, which can easily lead to bag breakage. Even if some devices have a support structure, the fixed size cannot meet the needs of different specifications of bags, thus limiting the versatility of the equipment. In terms of material handling, existing devices have poor adaptability to environmental humidity. When processing small-diameter powders, such as traditional Chinese medicine powder and nano-sized particles, they are prone to absorbing moisture and clumping in high humidity environments, and they adhere to the inner wall of the storage hopper. This not only affects the flowability of the material, leading to measurement errors, but also increases the difficulty of cleaning the equipment and maintenance costs.

[0004] In response to this technical problem, this application proposes a powder particle packaging machine suitable for different particle sizes. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing packaging technologies, such as poor compatibility of packaging bags, lack of flexible lifting structures, fixed sizes, insufficient material processing capacity, and the tendency of small-diameter materials to clump and stick to the walls under high humidity, affecting measurement and cleaning. This invention proposes a powder and particle packaging machine suitable for different particle sizes. This equipment solves the problems of existing equipment being unable to adapt to multiple sizes of packaging bags and being prone to bag breakage. Simultaneously, it utilizes a removable electric heating film inside the outer cylinder of the storage hopper to heat the hopper, preventing small-diameter materials from absorbing moisture, clumping, and sticking to the inner wall under high humidity, thus improving packaging efficiency and stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A powder and particle packaging machine suitable for different particle sizes includes a base, a support column fixedly connected to the rear end of the top of the base, a storage hopper installed on the front side of the support column, a discharge pipe fixedly connected to the bottom end of the storage hopper, a fixed seat fixedly connected to the top axis of the storage hopper, a scraper connected to the fixed seat through a drive assembly, slots on both the left and right sides of the base, positioning plates detachably connected to the inner walls of the slots, multiple positioning grooves on the top of the adjacent side of the positioning plates, and support plates detachably connected to the inner walls of the positioning grooves on both the left and right sides, with adjacent ends of the support plates slidably connected, a slide block fixedly connected to the bottom side of the left support plate, and a limit rod fixedly connected to the bottom of the right support plate, with the outer side of the limit rod slidably connected to the inner wall of the slide block, and a spring sleeved on the middle of the outer side of the limit rod.

[0008] Furthermore, an outer cylinder is fixedly connected to the top of the outer wall of the storage hopper, and multiple mounting plates are detachably connected to the inner wall of the outer cylinder. The multiple mounting plates are connected by trapezoidal blocks, and an electric heating film is provided on the inner wall of the mounting plate. A positioning component is provided on the top of the outer cylinder.

[0009] Furthermore, a connecting plate is detachably connected to the top of the base, and both the left and right ends of the bottom of the connecting plate penetrate the top side of the base and are detachably connected to the bottom end of the positioning plate. The positioning plate is L-shaped.

[0010] Furthermore, the drive assembly includes a motor, which is mounted on the top side of the fixed base. The motor drive end passes through the fixed base and is fixedly connected to a sleeve rod. An auger is provided on the inner wall of the sleeve rod, and the top end of the auger is fixedly connected to the motor drive end. A scraper is fixedly connected to the top outer end of the sleeve rod.

[0011] Furthermore, the outer wall of the scraper is in contact with the inner wall of the storage hopper, and multiple diverting rods are fixedly connected to the top inner side of the scraper. The top of the storage hopper is provided with a feed inlet.

[0012] Furthermore, the positioning component includes a pressure plate, a positioning bolt is fixedly connected to the bottom of the pressure plate, the positioning bolt is detachably connected to the top of the outer cylinder, a bolt is fixedly connected to the outer end of the bottom of the pressure plate, the bolt is threadedly connected to the outer cylinder, and one end of the bottom of the pressure plate abuts against the top of the mounting plate.

[0013] Furthermore, the trapezoidal block is fixedly connected to one end of the mounting plate, and the other end of the mounting plate is provided with a slot that matches the trapezoidal block.

[0014] Furthermore, a fixing block is fixedly connected to the top of the outer wall of the discharge pipe, and a connecting arm 1 is rotatably connected to the front and rear ends of the left and right sides of the fixing block.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, the bottom end of the positioning plate is slid into the slot of the base and then fixed with the connecting plate, which allows for quick installation and positioning. The support plate can flexibly adjust its lateral size and height between the positioning slots of the left and right positioning plates according to the size of the packaging bag. With the spring's reset support, it effectively solves the problems of existing equipment being unable to adapt to various packaging bag sizes and lacking a bottom support structure that makes the bags easy to break.

[0017] In this invention, an electric heating film that can be detachably installed inside the outer cylinder of the storage hopper is fixed by a pressure plate, positioning bolts and bolts. This allows the storage hopper to be heated in a high humidity environment, preventing small-diameter materials from absorbing moisture, clumping and adhering to the inner wall, thus overcoming the shortcomings of existing devices in processing fine powder in humid environments.

[0027] Reference Figures 1-3 This utility model provides an embodiment of a powder granule packaging machine suitable for different particle sizes, including a base 1, a support column 2 fixedly connected to the rear end of the top of the base 1, a storage hopper 3 installed on the front side of the support column 2, a discharge pipe 4 fixedly connected to the bottom end of the storage hopper 3, a fixed seat 7 fixedly connected to the top axis of the storage hopper 3, a scraper 10 connected to the fixed seat 7 through a drive assembly, slots 18 are provided on both the left and right sides of the base 1, a positioning plate 19 is detachably connected to the inner wall of the slot 18, a plurality of positioning grooves 20 are provided on the top of the adjacent side of the positioning plate 19, a support plate 22 is detachably connected to the inner wall of the positioning grooves 20 on both the left and right sides, the adjacent ends of the two support plates 22 are slidably connected, a slide 24 is fixedly connected to the bottom side of the left support plate 22, a limit rod 25 is fixedly connected to the bottom of the right support plate 22, the outer side of the limit rod 25 is slidably connected to the inner wall of the slide 24, and a spring 26 is sleeved on the middle of the outer side of the limit rod 25;

[0028] Specifically, the support column 2 at the top rear end of the base 1 fixes the storage hopper 3. The discharge pipe 4 at the bottom of the storage hopper 3, together with the motor 6 in the drive assembly, drives the sleeve rod 8 and the auger 9 to rotate, which can stir and convey the material. At the same time, the scraper 10 on the outer side of the sleeve rod 8 rotates against the inner wall of the storage hopper 3, which can prevent the material from sticking to the hopper wall and also work with the diverting rod 11 to evenly disperse the material. The slots 18 on the left and right sides of the base 1 are detachably connected to the L-shaped positioning plate 19. The connecting plate 21 passes through the base 1 and is fixed to the bottom of the positioning plate 19, which can be quickly installed and positioned.

The left end support plate 22 is slidably connected to the bottom limit rod 25 of the right end support plate 22 through the slide seat 24. The spring 26 sleeved on the outside of the limit rod 25 can provide reset support when the support plate 22 slides relative to each other, so that the support plate 22 can be adjusted laterally according to the size of the packaging bag. Then, the height of the support plate 22 is fixed by the positioning groove 20, thereby realizing the support of the bottom of packaging bags of different sizes and avoiding the impact of falling materials causing the bag to break.

[0029] Reference Figures 4-6 The outer wall of the storage hopper 3 is fixedly connected to the top of an outer cylinder 27. Multiple mounting plates 28 are detachably connected to the inner wall of the outer cylinder 27. These mounting plates 28 are connected by trapezoidal blocks 29. Heating films 30 are installed on the inner walls of the mounting plates 28. A positioning assembly is installed at the top of the outer cylinder 27. A connecting plate 21 is detachably connected to the top of the base 1.

The drive assembly includes a motor 6, which is mounted on the top side of a fixed base 7. The drive end of the motor 6 penetrates the fixed base 7 and is fixedly connected to a sleeve rod 8. An auger 9 is installed on the inner wall of the sleeve rod 8. The top end of the auger 9 is fixedly connected to the drive end of the motor 6. A scraper 10 is fixedly connected to the top outer side of the sleeve rod 8. The outer wall of the scraper 10 fits against the inner wall of the storage hopper 3. Multiple diverting rods 11 are fixedly connected to the top inner side of the scraper 10. The storage hopper 3 has a feed inlet 5 at the top; the positioning assembly includes a pressure plate 31, a positioning bolt 23 is fixedly connected to the bottom of the pressure plate 31, the positioning bolt 23 is detachably connected to the top of the outer cylinder 27, a bolt 32 is fixedly connected to the outer bottom of the pressure plate 31, the bolt 32 is threadedly connected to the outer cylinder 27, and the bottom end of the pressure plate 31 abuts against the top of the mounting plate 28; a trapezoidal block 29 is fixedly connected to one end of the mounting plate 28, and the other end of the mounting plate 28 has a slot that matches the trapezoidal block 29; a fixing block 12 is fixedly connected to the top of the outer wall of the discharge pipe 4, and a connecting arm 13 is rotatably connected to the front and rear ends of the left and right sides of the fixing block 12, a connecting arm 24 is rotatably connected to the bottom end of the connecting arm 13, a clamping plate 17 is provided at the bottom end of the connecting arm 24, and the outer walls of the front and rear ends of the connecting arm 13 are connected by an electric push rod 15, and a connecting rod 16 is fixedly connected to the bottom end of the connecting arm 13 on the side closest to it;

[0030] Specifically, inside the outer cylinder 27 at the top of the outer wall of the storage hopper 3, multiple mounting plates 28 are spliced ​​with slots via trapezoidal blocks 29. The electric heating film 30 on the inner wall of the mounting plate 28 can heat the storage hopper 3. The mounting plate 28 is fixed by the bottom positioning bolt 23 and bolt 32 of the pressure plate 31. It can heat and dry the material in the storage hopper 3 when the air humidity is high, preventing small-diameter materials from absorbing moisture, clumping, and adhering to the hopper wall. The connecting arm 13 and connecting arm 24 connected to the fixing block 12 on the outer wall of the discharge pipe 4 are driven to open and close by the electric push rod 15. This can drive the clamping plate 17 to clamp the bag mouth. With the help of the pallet 22, the material is accurately filled and the bag is protected from breakage. This device solves the problem that the existing equipment cannot adapt to different bag sizes through the adjustable structure of the pallet 22 and the positioning slot 20. The electric heating film 30 is used to heat the inner wall of the storage hopper 3 to make up for the defect of clumping and adhesion of small-diameter materials under high humidity. The coordinated work of each component improves the efficiency and stability of the packaging.

[0031] Working principle: When this powder and granule packaging machine is working, the material enters from the top feed inlet 5 of the storage hopper 3. The motor 6 drives the sleeve rod 8 and the auger 9 to rotate. The auger 9 conveys the material downward to the discharge pipe 4. At the same time, the scraper 10 on the outer side of the sleeve rod 8 rotates against the inner wall of the storage hopper 3 to prevent the material from sticking and disperses the material through the diverting rod 11. During packaging, the bottom end of the positioning plate 19 is first slid into the slot 18 of the base 1 and fixed with the connecting plate 21. Then, the tray 22 is adjusted according to the size of the packaging bag so that it retracts laterally under the cooperation of the limiting rod 25 and the sliding seat 24. 26 provides a reset support, which, after being adjusted to a suitable width, is inserted into the positioning groove 20 on the top side of the positioning plate 19 to fix the height, thereby achieving bottom lifting of packaging bags of different sizes; the electric push rod 15 at the discharge pipe 4 drives the connecting arm 13 and the connecting arm 24 to open and close, thereby driving the clamping plate 17 to clamp the opening of the packaging bag; when the ambient humidity is high, the electric heating film 30 inside the outer cylinder 27 is fixed by the pressure plate 31, the positioning bolt 23 and the bolt 32 and heats the storage hopper 3 to prevent small-diameter materials from absorbing moisture and clumping and adhering to the inner wall. All structures work together to complete the stable packaging of materials.
