Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging machine technology, specifically an adaptive bag-feeding machine cutting mechanism. Background Technology
[0002] In the packaging process of food, pharmaceuticals, and other fields, oxygen absorbers are often placed inside the packaging to extend the product's shelf life. The delivery of oxygen absorbers is usually accomplished by an oxygen absorber dispensing machine. The cutting mechanism of the dispensing machine is a key component, its function being to cut the continuous oxygen absorber packaging strip into individual oxygen absorber bags of a preset length. Therefore, the stability of the cutting mechanism directly affects product quality and production efficiency.
[0003] In existing deoxidizer bagging machines, the cutter, as a core component, needs to undergo high-speed shearing motion over extended periods and at high frequencies during machine operation. To reduce motion inertia and adapt to high-speed operation requirements, existing cutters are typically designed with a thinner structure. However, this thin cutter has significant drawbacks in practical use: Firstly, the structural strength of the thin cutter is limited, making it prone to bending and deflection deformation under high-frequency shearing stress. This leads to a decrease in the fit accuracy between the moving and stationary blades, resulting in uneven cutting surfaces and even incomplete cutting, affecting the sealing of the deoxidizer bag. Secondly, the stress concentration caused by deformation accelerates the wear and fatigue of the cutter edge, significantly shortening the cutter's service life.
[0004] Due to the short lifespan of the cutter, frequent machine shutdowns are required to replace the cutter during production. This not only increases the workload of maintenance personnel and the cost of cutter consumables, but also leads to production interruptions and reduces the overall operating efficiency of the equipment. In addition, insufficient cutter stability may cause a chain reaction of problems such as increased equipment vibration and noise, further affecting the overall operating status of the bagging machine. Utility Model Content
[0005] This utility model discloses an adaptive baggage handling machine cutting mechanism, which increases the thickness of the cutter and adds an adaptive support to ensure the stability of the cutter during the cutting motion and extend the service life of the cutter.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] This utility model discloses an adaptive baggage handling machine cutting mechanism, including a fixed blade and a movable blade. The fixed blade is installed at the lower end of a fixed blade mounting plate, which is installed at the lower end of an upper cover plate. A left side plate and a right side plate are installed at the lower end of the upper cover plate. One side of the fixed blade mounting plate is connected to the left side plate. The movable blade is installed on a movable blade holder. A linear bearing is installed on the right side plate. A guide rod is installed at one end of the movable blade holder, and the guide rod passes through the linear bearing and the right side plate. Guide strips are provided on both sides of the movable blade, and the guide strips are located between the fixed blade and the bearing. The bearing is installed on an adaptive bracket, and the top of the adaptive bracket is installed on one side of the fixed blade mounting plate.
[0008] Furthermore, the adaptive bracket includes a mounting plate 1, a bearing mounting plate, and a compression spring mounting plate. The top of the mounting plate 1 is connected to one side of the fixed blade mounting plate via a movable pin. The bearing mounting plate is connected to the bottom of the mounting plate 1. The compression spring mounting plate is installed at the end of the bearing mounting plate. The bearing mounting plate is perpendicular to the mounting plate 1, and the bearing is installed at one end of the bearing mounting plate.
[0009] Furthermore, the compression spring connects the compression spring mounting plate and the fixed blade mounting plate.
[0010] Furthermore, the blades of the fixed blade and the moving blade are set opposite each other.
[0011] Furthermore, there are two adaptive brackets, two compression springs, and two bearings.
[0012] Furthermore, the moving tool holder includes a moving tool mounting block, with two moving tool connecting plates at the rear end of the moving tool mounting block, and a moving tool connecting and fixing plate at the rear end of the moving tool connecting and fixing plate. A guide rod is installed at the middle of the rear end of the moving tool connecting and fixing plate, and the moving tool is mounted on the moving tool mounting block.
[0013] Furthermore, a cam is installed at the output end of the motor, a cam pin is installed at the end of the cam, and the end of the cam pin is connected to the moving blade connecting plate.
[0014] The beneficial effects of this utility model are:
[0015] This invention increases the thickness of the cutter and adds an adaptive bracket. The guide bar of the moving cutter is pressed against the lower end of the fixed cutter by the bearing. The compression spring continuously applies downward pressure to one end of the bearing mounting plate. Through the lever principle, the other end of the bearing mounting plate continuously applies upward force to the bearing. The bearing then continuously applies upward force to the guide bar, ensuring the stability of the moving cutter during the shearing motion and extending the service life of the cutter.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] As shown in the figure, this utility model discloses an adaptive baggage handling machine cutting mechanism, including a fixed blade 1 and a movable blade 2. The fixed blade 1 is installed at the lower end of a fixed blade mounting plate 3, which is installed at the lower end of an upper cover plate 4. A left side plate 5 and a right side plate 6 are installed at the lower end of the upper cover plate 4. One side of the fixed blade mounting plate 3 is connected to the left side plate 5. The movable blade 2 is installed on a movable blade holder 7. A linear bearing 8 is installed on the right side plate 6. A guide rod 9 is installed at one end of the movable blade holder 7. The guide rod 9 passes through the linear bearing 8 and the right side plate 6. Guide strips 10 are provided on both sides of the movable blade 2. The guide strips 10 are located between the fixed blade 1 and the bearing 13. The bearing 8 is installed on an adaptive bracket 11, and the top of the adaptive bracket 11 is installed on one side of the fixed blade mounting plate 3.
[0024] During operation, the moving blade holder 7 drives the moving blade 2 to move horizontally. Since the guide bar 10 is always pressed against the lower end of the bearing 13 and the fixed blade 1, the moving blade 2 also moves smoothly, ensuring the stability of the moving blade in the shearing motion and extending the service life of the cutter.
[0025] In one embodiment of this utility model, the adaptive bracket 11 includes a mounting plate 111, a bearing mounting plate 112, and a compression spring mounting plate 113. The top of the mounting plate 111 is connected to one side of the fixed blade mounting plate 3 via a movable pin 12. The bearing mounting plate 112 is connected to the bottom of the mounting plate 111. The compression spring mounting plate 113 is installed at the end of the bearing mounting plate 112. The bearing mounting plate 112 is perpendicular to the mounting plate 111. The bearing 13 is installed at one end of the bearing mounting plate 112.
[0026] In one embodiment of this utility model, a compression spring 14 connects a compression spring mounting plate 112 and a fixed blade mounting plate 3. The compression spring 14 applies downward pressure to the compression spring mounting plate 112. The compression spring mounting plate 112 applies downward pressure to the mounting plate 111. Since the upper end of the mounting plate 111 is connected by a movable pin 12, the compression spring mounting plate 112 can only rotate, and the other end of the compression spring mounting plate 112 moves upward, thereby driving the bearing 13 to move upward. This achieves pressure on the guide bar, ensuring stable movement of the guide bar, and thus ensuring stability of the movement of the moving blade.
[0027] In one embodiment of this utility model, the blades of the fixed blade 1 and the moving blade 2 are arranged opposite to each other, the cutting edge of the fixed blade is in contact with the cutting edge of the moving blade, and the two cutting edges slide alternately to apply shearing force to the material.
[0028] In one embodiment of this utility model, there are two adaptive brackets 11, two compression springs 14, and two bearings 13.
[0029] In one embodiment of this utility model, the movable tool holder 7 includes a movable tool mounting block 71. Two movable tool connecting plates 72 are provided at the rear end of the movable tool mounting block 71. A movable tool connecting and fixing plate 73 is provided at the rear end of the movable tool connecting and fixing plate 72. A guide rod 15 is installed at the middle of the rear end of the movable tool connecting and fixing plate 73. The movable tool 2 is mounted at the movable tool mounting block 71. Here, the movable tool holder 7 is not a fixed block; this is to facilitate the installation of the guide rod 15. One end of the guide rod 15 is located between the two movable tool connecting plates 72.
[0030] In one embodiment of this utility model, a cam 17 is mounted on the output end of the motor 16, and a cam pin 18 is mounted on the end of the cam 17. The end of the cam pin 18 is connected to the moving tool connecting plate 72. The motor 16 drives the cam 17 to rotate, and the guide rod 15 constrains the movement direction of the moving tool holder. The cam 17 drives the cam pin 18 to achieve horizontal movement. The cam pin 18 drives the moving tool holder 7 to move horizontally.
[0031] The moving and fixed blades of this invention can have a certain thickness, making them less prone to deformation during the shearing process. If the blades are too thin, they may bend or deflect under force, leading to a decrease in shearing efficiency or even failure. Therefore, appropriately increasing the thickness can maintain the effective transmission of shearing force.
[0032] like Figure 5 As shown, the motor 16 and the upper cover plate 4 are both mounted on the frame support plate 19, which is used to mount the entire cutting mechanism.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
