Description

Technical Field

[0001] This utility model relates to the field of material feeding and stacking technology, specifically to a material feeding and stacking device for an industrial packaging machine. Background Technology

[0002] Material stacking is mainly used to stack regular items together for better packaging. For example, stacking regular block-shaped items (such as soap) by quantity can simplify the process and adapt to standardized packaging scenarios. Material stacking is mainly completed by material stacking equipment.

[0003] For example, the prior art application number CN202420519814.5 discloses a receiving device for a fully automatic packaging machine, including a conveyor seat, a receiving box on the top of one side of the conveyor seat, a guide box fixedly installed inside the receiving box, a sealing cover at the bottom of the guide box, a swing arm rotatably installed on the outer wall of the receiving box, an adjustment frame rotatably installed at one end of the swing arm, a lead screw rotatably installed on the adjustment frame, a matching slider slidably installed on the outer wall of the lead screw, and the end of the swing arm away from the receiving box rotatably connected to the outer wall of the slider.

[0004] The aforementioned prior art, as demonstrated by practical use, involves materials being stacked in a receiving bin and then falling onto an electric conveyor belt by gravity after a valve is opened. However, this method is prone to tipping over: when the material falls too quickly under gravity, the impact force on the conveyor belt is significant, causing the stacked material to momentarily shift its center of gravity, making it prone to tipping over. Therefore, we have improved the aforementioned prior art based on actual usage. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, this utility model is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An industrial packaging machine unloading and stacking device includes a base. A receiving box and an electric conveyor belt are fixed to the upper end of the base. A valve-type electronic scale is fixed to the lower outlet of the receiving box. A U-shaped guide frame is welded to the upper end of the base opposite to the lower outlet of the receiving box, and a ball is rotatably arranged on the inner wall of the U-shaped guide frame. Adjusting components are provided on the front and rear outer sides of the U-shaped guide frame. The adjusting components are a retaining block and an electric telescopic rod for controlling the movement of the retaining block. The inner side of the retaining block abuts against the outer surface of the ball to provide resistance to the ball.

[0009] Furthermore, a controller is fixed to one side of the receiving box by bolts, and the front and rear sides of the receiving box are fixed to the base by connecting frames.

[0010] Furthermore, one end of the electric conveyor belt is located within the opening of the U-shaped guide frame and is surrounded by the U-shaped guide frame. The front and rear inner walls of the U-shaped guide frame are embedded with rotating spheres, and a portion of the spheres is located outside the U-shaped guide frame.

[0011] Furthermore, the front and rear sides of the U-shaped guide frame are fixed to the electric telescopic rod by bolts, and the output end of the electric telescopic rod is fixed with a connecting frame. A cylinder is welded to the inner side of the connecting frame, and a retaining block is elastically movable inside the cylinder.

[0012] Furthermore, one end of the abutting block is provided with an arc-shaped groove for abutting against the outer surface of the sphere, and a pressure sensor is fixed at the axis of the arc-shaped groove.

[0013] Furthermore, the abutting block is slidably disposed with respect to the inner wall of the cylinder via a slider, and a spring is welded between one end of the abutting block and the end wall of the cylinder.

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

[0015] 1. By using the physical limiting structure of the U-shaped guide frame to restrict the lateral displacement of the material, and by cooperating with the electric telescopic rod, pressure sensor and clamping block in the adjusting component, a suitable rotational resistance is obtained, which achieves adjustable damping effect to reduce the falling speed of the material and avoid the center of gravity shifting due to the excessive falling speed of the material caused by gravity, thus solving the problem of material tipping.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution: an industrial packaging machine unloading and stacking device, including a base 1, a receiving box 2 and an electric conveyor belt 3 fixed at the upper end of the base 1, and a valve-type electronic scale 8 fixed at the lower end of the receiving box 2 discharge port; a U-shaped guide frame 4 is welded to the upper end of the base 1 opposite to the lower end of the receiving box 2, and a ball 5 is rotatably arranged on the inner wall of the U-shaped guide frame 4; adjusting components 6 are arranged on the front and rear outer sides of the U-shaped guide frame 4; the adjusting component 6 is a pressing block 62 and an electric telescopic rod 63 that controls the movement of the pressing block 62, and the inner side of the pressing block 62 abuts against the outer surface of the ball 5 to provide resistance to the ball 5;

[0030] It should be noted that the recommended electrical models are as follows: For valve-type electronic scales, choose Teraoka DIGI-RX10K (0-10kg capacity, ±2g accuracy); for electric telescopic rods, choose UT-100 (100mm stroke, 500N thrust); and for electric conveyor belts, choose Interroll 300 series (400mm width, 0-1.5m / s speed). Compared to traditional equipment, this equipment has a material tipping rate ≤3%, stacking deviation ≤5mm, and increases production capacity to 120-150 pieces / minute.

[0031] refer to Figure 1 The receiver 2 is bolted to one side, and the receiver 2 is fixed to the base 1 via connecting brackets. The controller 7 is a Siemens S7-200SMART (12DI / 8DO, supports Modbus).

[0032] refer to Figure 1 One end of the electric conveyor belt 3 is located inside the opening of the U-shaped guide frame 4 and is surrounded by the U-shaped guide frame 4 to prevent materials from falling. The front and rear inner walls of the U-shaped guide frame 4 are embedded with rotating spheres 5, and a part of the spheres 5 is located outside the U-shaped guide frame 4 to facilitate the setting of its resistance.

[0033] refer to Figure 3 and Figure 4The front and rear sides of the U-shaped guide frame 4 are fixed to the electric telescopic rod 63 by bolts, and the output end of the electric telescopic rod 63 is fixed to the connecting frame 64. A cylinder 61 is welded to the inner side of the connecting frame 64, and a retaining block 62 is elastically and movable inside the cylinder 61. One end of the retaining block 62 is provided with an arc-shaped groove for abutting against the outer surface of the ball 5, and a pressure sensor 66 is fixed to the axis of the arc-shaped groove. The retaining block 62 is slidably set against the inner wall of the cylinder 61 by a slider, and a spring 65 is welded between one end of the retaining block 62 and the end wall of the cylinder 61. The pressure sensor 66 is selected as MEASFS200 (range 0-100N, output 4-20mA), and the spring 65 provides elastic buffer for the retaining block 62 to prevent the ball 5 from rigidly jamming; the retaining block 62 is made of aluminum alloy and has good heat dissipation.

[0034] It should be noted that the resistance and rotation speed of the ball 5 are as follows: The recommended resistance of the ball 5 is 5-15N, so that when materials weighing less than 10 catties (about 5 kg) fall, the rotation speed of the ball 5 is stabilized at 50-150 r / min, and the rolling friction is used to reduce the speed of the material to 0.2-0.5 m / s, which is suitable for electric conveyor belt 3.

[0035] The electric telescopic rod 63 works in conjunction with the pressure sensor 66 to control the pressure between 8-20N. Based on this pressure, the electric telescopic rod 63 dynamically adjusts the pressure of the clamping block 62 on the ball 5 to ensure stable resistance and allow the material to fall smoothly onto the conveyor belt. In practice, the precise value needs to be determined through testing (e.g., simulating materials with different weights and adjusting parameters to observe the stability of the material falling) before initial settings are applied to the controller 7.

[0036] Working principle: The base 1 supports the receiving box 2 and the electric conveyor belt 3. The valve-type electronic scale 8 weighs the material in the receiving box 2 in real time. When the set value is reached, the controller 7 opens the valve, and the material falls into the U-shaped guide frame 4 through the discharge port of the receiving box 2. During the fall, it contacts the inner wall ball 5. The ball 5 is pushed and rolled by the material. At this time, the electric telescopic rod 63 in the adjusting component 6 pushes the connecting frame 64 to drive the pressing block 62 in the cylinder 61 to press against the ball 5. The pressure sensor 66 in the arc groove of the pressing block 62 feeds back the pressure signal to the controller 7 to adjust the extension of the electric telescopic rod 63 to accurately control the pressing force, thereby changing the rotation resistance of the ball 5. The spring 65 provides elastic buffer for the pressing block 62 to avoid rigid jamming. Finally, the material falls into the electric conveyor belt 3 to transport the material and achieve stable stacking.

[0037] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
