Description

Technical Field

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

[0002] The bag support device of a cement packaging machine is one of the core components of an automated cement packaging system. It is mainly used to stably support cement bags during the filling process, ensuring filling accuracy, reducing bag breakage, and improving packaging efficiency. It typically works in conjunction with a weighing system, bag clamping mechanism, conveyor belt, etc., to achieve an automated packaging process.

[0003] Chinese Patent No. CN204776479U discloses a bag-supporting device for a cement packaging machine, including a packaging frame and a bag-supporting frame. The packaging frame is fixedly connected to the cement packaging machine frame next to the filling port and includes two vertical rods. The bag-supporting frame is a double-forked frame composed of two symmetrical horizontal rods. One end of each horizontal rod is fixed to the bottom end of the two vertical rods of the packaging frame, making the bag-supporting frame and the packaging frame form an L-shaped structure. A cement filling space is formed between the bag-supporting frame and the filling port of the cement packaging machine. A bag-supporting tray is welded onto the bag-supporting frame. The bag-supporting tray is an elliptical steel ring with an arc structure, so that the side of the bag-supporting tray near the filling port of the cement packaging machine has a bag-supporting recess. This utility model has the characteristics of simple structure and is not easy to accumulate dust. It can effectively ensure the force balance of the packaging bag and avoid the situation of tilting or falling of the packaging bag due to uneven force during the filling process.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing cement packaging machine's bag-holding device cannot quickly install cement bags during use, and the weighing during the cement filling process cannot guarantee that each bag of cement has the same quality. At the same time, it cannot drive the cement bags to automatically lift and lower to control the installation of cement bags and cement outlets, thus slowing down the cement bagging efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where cement bags cannot be quickly installed and weighed, and where cement bags cannot be automatically lifted and lowered. This invention proposes a cement packaging machine bag support device.

[0006] The technical solution of this utility model: a cement packaging machine pallet holder, including a base frame; and further including:

[0007] The lifting mechanism, located on the base frame, is used to lift the cement bag to the cement outlet after the cement bag is installed.

[0009] The bagging ring is located at the top of the receiving mechanism. A clamping ring is engaged on the inner side of the bagging ring. An annular groove is provided on the bagging ring. The mouth of the cement bag is placed on the annular groove, and then the receiving mechanism drives the clamping ring to clamp the bagging ring, thereby pressing the mouth of the cement bag into the annular groove, thus fixing the cement bag for receiving. The inner side of the bagging ring is used to fit with the cement outlet, so that the bagging ring and the cement outlet are in close contact.

[0010] Preferably, the lifting mechanism includes a slide rail, rollers, connecting shaft, connecting frame, and lifting assembly;

[0011] A slide groove is located inside the bottom frame, a roller is located inside the slide groove, a connecting shaft is located on the side of the roller and is used to connect the rollers on both sides, and a connecting frame is located outside the connecting shaft.

[0012] The lifting assembly is mounted on the base frame and is used to move the cement bag up and down.

[0013] Preferably, the lifting assembly includes a cylinder, a lifting rod, a connecting block, and a connecting frame.

[0014] A cylinder is located at the end of connecting frame one away from the connecting shaft. A lifting rod is located at the output end of the cylinder. A connecting block is located at the end of the lifting rod away from the cylinder. Connecting frame two is rotatably located on the outside of connecting block two. A connecting rod is located at the end of connecting frame two away from the connecting block. A rotating rod one is located at the end of the connecting rod. A fixing block one is rotatably located at the bottom of rotating rod one. A sliding block one is rotatably located at the top of rotating rod one. A sliding groove two is rotatably located at the top of sliding block one. A rotating rod two is rotatably located on the side of rotating rod one. The bottom of rotating rod two is rotatably connected to the outside of the connecting shaft. A fixing block two is rotatably located at the top of rotating rod two.

[0015] Preferably, the receiving mechanism includes a weighing component and a bag opening installation component;

[0016] The bag opening mounting assembly is located on the top of the lifting plate and is used to install and fix the cement bags.

[0017] The weighing component is located inside the bag opening mounting component and is used to weigh the received cement and trigger an alarm when the specified weight is reached.

[0018] Preferably, the bag opening mounting assembly includes a support plate, a fixing frame, a sliding rod, and a spring.

[0019] The support plate is located on top of the lifting plate, the fixing frame is located on the outside of the bagging ring, the sliding rod is slidably located on top of the fixing frame, and a spring is provided on the outside of the sliding rod.

[0020] Preferably, the weighing assembly includes a platform, a telescopic rod, and a spring.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] 1. Through the setting of the lifting mechanism, the cylinder drives the rotating rod one and rotating rod two to rotate upward through the lifting rod, thereby driving the cement bag to move upward through the lifting plate. This eliminates the need for frequent manual height adjustment of the cement bag during the packaging process, thereby reducing manual intervention, increasing packaging speed, and enabling continuous and stable lifting of the cement bag to achieve continuous operation, further improving packaging efficiency.

[0024] 2. The cement bag opening is installed via a receiving mechanism that connects the clamping ring and the filling ring. After installation, the filling ring rises to tightly seal against the cement conveyor opening, allowing cement to be filled. Once the bag reaches the appropriate weight, it is placed on a platform to contact the controller, triggering an alarm to remind staff to close the cement conveyor opening. This simple lifting action quickly and accurately secures the cement bag opening below the conveyor opening, reducing manual operation time and improving the continuity of the packaging process. The tight connection between the filling ring and the cement conveyor opening prevents cement dust from spilling during filling, reducing dust pollution to equipment and the environment, and lowering cleaning and maintenance costs. Real-time weighing and alarm functions prevent damage to the packaging bags or transportation risks caused by overloading. Attached Figure Description
