Description

Technical Field

[0001] The utility model relates to the technical field of product packaging devices, in particular to a product packaging device that safely prevents material accumulation. Background Art

[0002] In the modern packaging industry, with the advancement of automation technology, packaging equipment has become an indispensable component in the production of various products. Especially in industries such as food, chemicals, and pharmaceuticals, the performance of packaging equipment directly impacts product quality, production efficiency, and overall production costs. Traditional packaging systems typically consist of multiple mechanical components, among which the bag gripper, a key component in the packaging process, is responsible for accurately guiding materials into the bag. However, a common technical issue with existing product packaging system designs is that materials tend to accumulate inside the bag gripper housing during the packaging process, impacting the normal operation of the equipment.

[0003] A Chinese patent discloses: a filling device and rice quantitative packaging equipment, patent announcement number: CN220199644U, the patent "comprises: an outer shell, an inner cylinder is installed in the middle of the outer shell, an inlet hopper is installed on the upper part of the inner cylinder, a discharge hopper is installed on the lower part of the inner cylinder, slide grooves are provided on both sides of the inner cylinder, fixed plates are installed on the upper and lower parts of both sides of the inner cylinder, sliding rods are fixed on the sides of the fixed plates on the same side close to each other, sliders are sliding on the outer periphery of the sliding rods, and blocks are fixed on the sides of the sliders close to each other; and fixed rods are provided on both sides of the lower part of the block, and support plates are installed on the lower part of the fixed rods."

[0004] Although this device uses the weight of the rice itself and the elastic force of the spring to move the block in the inner barrel up and down, thereby achieving intermittent opening and closing of the upper and lower hoppers, thereby achieving the purpose of quantitative filling and facilitating the quantitative filling of rice by staff, the device does not have a knocking mechanism, which can easily lead to material blockage in the pipeline. Due to the different physical properties of the materials, such as when the rice is slightly damp or has strong static electricity, the particles may stick together, reducing fluidity and easily clogging the bag holder housing. At the same time, during the packaging process, especially for some easily adhered powdery or granular materials, the materials can easily adhere to the inside of the bag holder housing. As the packaging process proceeds, these attached materials will gradually accumulate and may eventually fall into the packaging bag due to gravity or vibration, resulting in excessive packaging materials, seriously affecting the packaging accuracy and quality of the product, and being more inconvenient to use.

[0025] like Figures 1 to 5 As shown, a product packaging device that safely prevents material accumulation includes a support frame 1, the top of the support frame 1 is fixedly connected to a storage bin 2, the bottom of the storage bin 2 is fixedly connected to a bag clamp cover 3, the outer wall of the bag clamp cover 3 is fixedly connected to a bag clamp 4, the bottom of the support frame 1 is fixedly connected to a weight scale 5, the four corners of the top of the weight scale 5 are fixedly connected to spring telescopic rods 6, the tops of the spring telescopic rods 6 are fixedly connected to weighing plates 7, and a knocking mechanism for preventing material accumulation is provided between the weighing plate 7 and the side wall of the bag clamp cover 3.

[0026] For further information, see the attached Figures 1 to 5As shown, the knocking mechanism includes a rotating rod 8 rotatably connected to the side wall of the weight scale 5 through a support plate, the outer wall of the rotating rod 8 is fixedly connected to a gear 9, the side wall of the weighing plate 7 is fixedly connected to a rack 10, the outer wall of the gear 9 is meshed with the side wall of the rack 10, one end of the rotating rod 8 is fixedly connected to a rotating plate 11, the side wall of the rotating plate 11 is rotatably connected to a ratchet 12, both sides of the rotating plate 11 close to the ratchet 12 are rotatably connected to a ratchet limit block 13, the outer wall shape of the ratchet limit block 13 is arc-shaped and one end of the ratchet limit block 13 is in contact with the outer wall of the ratchet 12, the side walls of the ratchet limit block 13 are fixedly connected to a tension spring 14, one end of the tension spring 14 is fixedly connected to the side wall of the rotating plate 11, the knocking mechanism also includes a fixed connection to the support frame 1 The mounting plate 15 of the side wall is provided with a through slot 16 on the top of the mounting plate 15. The top of the mounting plate 15 is rotatably connected to a rotating column 17 through a fixed plate. A belt 18 is provided between the outside of one end of the rotating column 17 and the outer wall of one end of the rotating rod 8 through a pulley sleeve. The middle part of the rotating column 17 is fixedly connected to an eccentric block 19. The top of the mounting plate 15 is rotatably connected to a knocking rod 20. The bottom of the knocking rod 20 contacts the outer wall of the eccentric block 19. A side of the knocking rod 20 close to the mounting plate 15 is fixedly connected to a reciprocating spring 21. One end of the reciprocating spring 21 is fixedly connected to the top of the mounting plate 15. The end of the knocking rod 20 close to the bag clamp cover 3 is fixedly connected to a knocking hammer 22. The side wall of the knocking hammer 22 fits into the outer wall of the bag clamp cover 3.

[0027] When the knocking mechanism is in use, the packaging bag is first clamped at the bottom end of the bag clamp cover 3 through the bag clamp 4 for packaging operation. After the material in the storage bin 2 is poured into the packaging bag, the weight of the packaging bag increases and squeezes the weighing plate 7. After being squeezed, the weighing plate 7 squeezes the spring telescopic rod 6. Then the height of the weighing plate 7 is lowered and drives the rack 10 to move downward. When the rack 10 moves downward, it drives the gear 9 to rotate. When the gear 9 rotates, it drives the rotating rod 8 to rotate. Then the rotating rod 8 drives the rotating plate 11 to rotate. When the rotating plate 11 rotates, it drives the ratchet limit block 13 to rotate. By pulling one end of the ratchet limit block 13 by the tension spring 14, the other end of the ratchet limit block 13 is engaged with the outer wall of the ratchet 12 and drives the ratchet 12 to rotate. When the ratchet 12 rotates, the rotating column 17 is driven to rotate through the belt 18, and then the rotating column 17 drives the eccentric block 19 to rotate. Because the eccentric block 19 is eccentrically installed, the outer wall of the eccentric block 19 will push up the knocking rod 20. At this time, one end of the knocking rod 20 will drive the knocking hammer 22 to lift up and pull The reciprocating spring 21 is activated, and the gravity of the knocking hammer 22 and the contraction of the reciprocating spring 21 pull the knocking rod 20 to rotate in the direction of the bag clamp cover 3, so that the knocking hammer 22 knocks on the outer wall of the bag clamp cover 3, thereby knocking down the logistics accumulated in the bag clamp cover 3. Through the knocking function of the knocking mechanism, the equipment can automatically knock when the material begins to accumulate, effectively shaking the material attached to the inside of the bag clamp cover 3 back into the packaging bag in time. This active cleaning design can be performed during each filling process to ensure that the material can smoothly enter the packaging bag, avoiding packaging weight deviation caused by material accumulation or sudden overweight during the packaging process. This function significantly improves the accuracy of each packaging operation, so that the weight of the material in the packaging bag is always kept within the predetermined range, which not only effectively prevents overweight packaging, but also ensures the consistency and quality stability of the product. Especially in industries with strict requirements on packaging weight, this improvement ensures high accuracy and reliability of packaging operations and is easy to use.
