Description

Technical Field

[0001] This utility model relates to the field of cement packaging machine technology, specifically a packaging machine that can be re-inspected and weighed. Background Technology

[0002] A cement packaging machine is a specialized piece of equipment used for packaging bulk materials such as cement. It is typically automated, efficiently and accurately filling cement into bags. Cement packaging machines not only improve production efficiency and reduce labor costs, but also effectively prevent material waste and pollution, and are widely used in industries such as cement production, building materials, and chemicals.

[0003] However, some existing cement packaging machines use ordinary brackets to support cement bags. Although the output of cement packaging machines is usually fixed, some cement powder may spill onto the outside of the bags during the filling process. Therefore, the cement needs to be weighed after packaging. Usually, other equipment is used for weighing. This method is inconvenient for workers to quickly check and understand the packaging weight of the cement, which reduces the work efficiency of cement packaging. Therefore, the current packaging machines need to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a packaging machine that can re-inspect and weigh cement, in order to solve the problems mentioned in the background art that current cement packaging machines on the market are inconvenient to weigh cement in a timely manner and that cement bags are not placed stably.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging machine capable of re-inspection and weighing, comprising a machine body and a base plate, a protective cover connected to one side of the machine body, a feeding hopper installed above the machine body, a discharge nozzle provided on one side of the machine body, a support installed on the side of the machine body near the discharge nozzle, the base plate connected to one side of the support, upright plates connected to both sides of the base plate, an auxiliary mechanism installed on one side of the upright plates, a weight sensor connected above the base plate, and a support plate installed above the weight sensor.

[0006] Preferably, the auxiliary mechanism includes a rotating seat, a baffle, and an electric push rod, with the rotating seat installed on one side of the upright plate.

[0007] Preferably, a baffle is movably sleeved on one side of the rotating seat, and an electric push rod is connected to one end of the baffle and the upright plate via a movable shaft.

[0008] Preferably, an adsorption component is installed on the side of the bracket near the discharge nozzle, and a push plate is installed on the inner side of the bracket via a rotating shaft.

[0009] Preferably, a pushing component is connected to one side of the push plate, and one side of the pushing component is connected to the bracket.

[0010] Preferably, a support frame is connected to the lower part of the protective cover, and a clamping mechanism is connected to the lower part of the support frame.

[0011] Preferably, the clamping mechanism includes a cylinder, a gripper, a support plate, a first rotating shaft, and a second rotating shaft, with the first rotating shaft installed at both ends of the support frame.

[0012] Preferably, a gripper is movably sleeved on the outer side of the first rotating shaft, and a cylinder is fixed in the middle of the support frame.

[0013] Preferably, a support plate is connected below the cylinder, and a second rotating shaft is installed at both ends of the support plate. The second rotating shaft is movably connected to the gripper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Equipped with a weighing sensor and auxiliary mechanism, the cement bag is supported by a pallet below it after filling. Simultaneously, the weight sensor detects the weight of the cement bag, and a baffle prevents the bag from tipping over and sliding outside the pallet area during weighing. After inspection and weighing, the electric push rod retracts, causing it to rotate the baffle on the rotating seat. The baffle then rotates open, facilitating the removal of the cement bag from the pallet. This immediate inspection and weighing after cement filling improves the efficiency and practicality of the packaging machine.

[0016] 2. A clamping mechanism is provided. By placing one end of the cement bag opening onto the discharge nozzle and simultaneously activating the cylinder to pull the support plate upward, the support plate causes one end of the gripper to rotate on the second rotating shaft, while the middle of the gripper rotates on the first rotating shaft. This allows the tip of the gripper to clamp one end of the bag, restricting the bag's position and preventing it from falling off. This provides auxiliary support for the vacuum adsorption structure and improves the working stability of the packaging machine. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a packaging machine capable of re-inspection and weighing, comprising a body 1 and a base plate 11. A protective cover 2 is connected to one side of the body 1. A feeding hopper 3 is installed on the top of the body 1. A discharge nozzle 4 is provided on one side of the body 1. A bracket 10 is installed on the side of the body 1 near the discharge nozzle 4. The base plate 11 is connected to one side of the bracket 10. An adsorption component 5 is installed on the side of the bracket 10 near the discharge nozzle 4. A push plate 9 is installed on the inner side of the bracket 10 via a rotating shaft. A pushing component 7 is connected to one side of the push plate 9. One side of the pushing component 7 is connected to the bracket 10.

[0025] Please see Figures 1-4 The base plate 11 has upright plates 15 connected to both sides. An auxiliary mechanism 8 is installed on one side of the upright plate 15. A weight sensor 13 is connected to the top of the base plate 11. A support plate 12 is installed above the weight sensor 13. The auxiliary mechanism 8 includes a rotating seat 801, a baffle 802, and an electric push rod 803. The rotating seat 801 is installed on one side of the upright plate 15. The baffle 802 is movably sleeved on one side of the rotating seat 801. An electric push rod 803 is connected to one end of the baffle 802 and the upright plate 15 through a movable shaft. The baffle 802 is designed as an arc-shaped plate structure. The weight sensor 13 is a piezoelectric sensor.

[0026] In practice, some cement packaging machines use ordinary support brackets to hold cement bags. Although the output of the cement packaging machine is usually fixed, some cement powder may spill onto the outside of the bag during the filling process. Therefore, the cement needs to be weighed after packaging. Usually, other equipment is used for weighing. This method is inconvenient for workers to quickly check and understand the weight of the cement packaging, reducing the efficiency of cement packaging. After the cement is filled, the support plate 12 under the cement bag supports the cement bag. At the same time, the weight sensor 13 senses the weight of the cement bag, and the baffle 802 blocks the cement bag to prevent it from tipping over and sliding outside the range of the support plate 12 during weighing. After the cement bag is checked and weighed, the electric push rod 803 is activated to retract, causing the electric push rod 803 to pull the baffle 802 to rotate on the rotating seat 801. Then the baffle 802 rotates open, making it easy for the cement bag to fall off the support plate 12. By checking and weighing the cement immediately after filling, the working efficiency and practicality of the packaging machine are improved.

[0027] Please see Figures 1-3 and Figure 5 A support frame 14 is connected to the lower part of the protective cover 2, and a clamping mechanism 6 is connected to the lower part of the support frame 14. The clamping mechanism 6 includes a cylinder 601, a gripper 602, a support plate 603, a first rotating shaft 604, and a second rotating shaft 605. The first rotating shaft 604 is installed at both ends of the support frame 14, and the gripper 602 is movably sleeved on the outer side of the first rotating shaft 604. The cylinder 601 is fixed in the middle of the support frame 14, and the support plate 603 is connected to the lower part of the cylinder 601. The second rotating shaft 605 is installed at both ends of the support plate 603, and the second rotating shaft 605 is movably sleeved with the gripper 602.

[0028] In practice, when the packaging machine is filling cement, it usually covers the bag opening onto the outside of the discharge nozzle 4 and uses a vacuum adsorption structure to adsorb and limit the bag. However, relying solely on the vacuum adsorption structure is not stable enough, and the bag is prone to falling off. To address this, one end of the cement bag opening is covered onto the discharge nozzle 4, and the cylinder 601 is activated to pull the support plate 603 upward. This causes the support plate 603 to rotate one end of the gripper 602 on the second rotating shaft 605, while the middle of the gripper 602 rotates on the first rotating shaft 604. This allows the tip of the gripper 602 to clamp one end of the bag, limiting its position and preventing it from falling off. This provides auxiliary support for the vacuum adsorption structure and improves the working stability of the packaging machine.

[0029] Working principle: When using this re-inspection weighing packaging machine, firstly, one end of the cement bag is placed on the discharge nozzle 4. Then, the machine body 1 controls the discharge nozzle 4 to discharge cement into the cement bag. At the same time, the adsorption component 5 and the clamping mechanism 6 limit the two ends of the bag. After filling, the weight of the cement bag is sensed by the weight sensor 13 and the pallet 12, which makes it convenient for the staff to check and understand the weight of the cement in time. At the same time, the auxiliary mechanism 8 supports the cement bag to prevent it from tipping over and slipping. After weighing, the push component 7 drives the push plate 9 to tilt and push the cement bag off the pallet 12, completing the cement packaging work. This improves the working efficiency and stability of the packaging machine. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
