Description

Technical Field

[0001] This utility model relates to the field of container sealing strip technology, specifically to a cutting device for processing container sealing strips. Background Technology

[0002] Container sealing strips, also known as I-beam rubber strips, are products specifically designed for sealing the door frames of shipping containers. They are typically made of materials such as PVC or EPDM rubber. Based on their function, they can be classified into weatherproof sealing strips and airtight sealing strips. Under normal circumstances, they can be used for at least five years. Common sealing strips need to be cut to the required length after production.

[0003] According to Chinese Patent Publication No. CN212795073U, entitled "A Cutting Device for Processing Container Sealing Strips," the main description involves activating a first cylinder to move a movable plate downwards, causing a pressure plate and a cutting blade to move downwards together. The pressure plate first contacts and holds the sealing strip, then a spring is compressed, and the cutting blade cuts the sealing strip. The conveyor table maintains a constant conveying speed for the sealing strip. A photoelectric gate sensor monitors the moving speed of the sealing strip. By controlling the propulsion frequency of the first cylinder, the cutting blade cuts the sealing strip to ensure equal cut lengths. After the sealing strip is cut, a linear motor is activated to move the clamping mechanism to a dense position. The sealing strip is placed at the top. Then, the second cylinder is activated to move the clamping mechanism downwards. At the same time, the rotary motor is adjusted to rotate the threaded rod. The sliding block is connected to the slide rail, which restricts the movement of the movable block. The two movable blocks can move relative to each other through the threaded hole and the threaded rod, driving the clamping plate to move relative to each other, thereby clamping and fixing the sealing strip. Then, the linear motor is adjusted to move the clamped sealing strip to the right until the sealing strip moves to the top of the guide plate. Then, the rotary motor is adjusted to release the sealing strip from the clamping plate. The sealing strip is guided by the guide plate and falls into the receiving bin, realizing the unloading of the sealing strip. The whole device has a high degree of automation and is less labor-intensive than manual unloading.

[0004] When common I-beam rubber strips are cut into strips of equal length, the cutting structure can cause the strips to be squeezed by the cutting structure, resulting in the strips swaying during the cutting process and thus leading to poor cutting accuracy.

[0005] Therefore, a cutting device for processing container sealing strips is proposed to solve the problem that the I-beam rubber strip will swing due to the compression of the cutting structure during the cutting process, which affects the cutting accuracy. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the I-beam rubber strip is squeezed by the cutting structure during the cutting process, which causes the I-beam rubber strip to swing and affects the cutting accuracy. Therefore, a cutting device for processing container sealing strips is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a cutting device for processing container sealing strips, including a fixed plate and a limiting plate. A limiting groove is opened at the upper end of the fixed plate. A bidirectional screw is rotatably connected in the limiting groove. Clamping plates are threaded to both sides of the bidirectional screw that are far apart from each other. An electric push rod is fixedly connected to one side of each of the two limiting plates. A pressure plate is fixedly connected to the output end of the electric push rod. A vertical plate is fixedly connected to the upper side of the limiting plate. A first motor is fixedly connected to one side of the limiting plate. A first screw is fixedly connected to the output end of the first motor. A moving frame is threaded to the first screw. A cutting blade is rotatably connected in the moving frame. A limiting hole is opened on one side of the fixed plate. A moving plate is in contact with the limiting hole. An extension rod is fixedly connected to one end of the moving plate. A spring is sleeved on the extension rod and the spring is located in the limiting hole. A baffle is fixedly connected to one side of the extension rod. An adjusting ring is threadedly connected to the extension rod.

[0008] As a preferred technical solution of this utility model, a support plate is fixedly connected to one side of the baffle. The support plate is at the same height as the clamping plate. By setting the support plate, one end of the sealing strip can be supported.

[0009] As a preferred technical solution of this utility model, a support rod is rotatably connected to one of the clamping plates, and the support rod is movably inserted into another clamping plate. A connecting ring is threaded onto the support rod. By setting the support rod and the connecting ring, the two clamping plates can be made more stable.

[0010] As a preferred technical solution of this utility model, a support frame is fixedly connected to the upper end of the fixing plate, a second motor is fixedly connected to one side of the support frame, and a guide wheel is fixedly connected to the output end of the second motor. By setting the guide wheel, the cut sealing strip can be guided.

[0011] As a preferred technical solution of this utility model, a horizontal plate is provided on the upper side of the guide wheel, the horizontal plate is fixedly connected to the upper side of the limiting plate, and a pressure rod is threadedly connected to the horizontal plate. A pressure ball is rotatably embedded at the bottom end of the pressure rod. By setting the pressure rod and the pressure ball, it can cooperate with the guide wheel to facilitate the movement of the sealing strip.

[0012] This utility model has the following advantages: by setting four opposing clamping plates and pressure plates on the fixed plate, the sealing strip is limited, which can increase the stability of the sealing strip when the cutting wheel is cutting. At the same time, by setting a bidirectional screw to rotate, the relatively adjustable clamping plate spacing can be changed. And by using the support rod and connecting ring, it can adapt to sealing strips of different widths and improve the stability of the clamping plates. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3The cutting device for processing container sealing strips includes a fixed plate 1 and a limiting plate 2. A limiting groove 3 is formed on the upper end of the fixed plate 1, and a bidirectional lead screw 4 is rotatably connected within the limiting groove 3. Rotating the bidirectional lead screw 4 causes clamping plates 5 to move relative to each other, thereby adapting to different widths of container sealing strips. Clamping plates 5 are threaded to both opposite sides of the bidirectional lead screw 4, forming a cutting recess between the four clamping plates 5. Electric push rods 6 are fixedly connected to opposite sides of the two limiting plates 2. The electric push rods 6 can drive pressure plates 7 closer to the clamping plates 5, thereby limiting the container sealing strip and improving its stability during cutting. A pressure plate 7 is fixedly connected to the output end of the electric push rod 6. A vertical plate 8 is fixedly connected to the upper side of the limiting plate 2, and a second vertical plate 8 is fixedly connected to one side of the limiting plate 2. A motor drives a first screw 9 to rotate, causing the moving frame 10 to move relative to the two limiting plates 2. The output end of the first motor is fixedly connected to the first screw 9, and the moving frame 10 is threadedly connected to the first screw 9. A cutting blade is rotatably connected inside the moving frame 10. A limiting hole 11 is opened on one side of the fixed plate 1, and a moving plate 12 contacts the limiting hole 11. An extension rod 13 is fixedly connected to one end of the moving plate 12. A spring is sleeved on the extension rod 13 and the spring is located inside the limiting hole 11. A baffle 14 is fixedly connected to one side of the extension rod 13, and an adjusting ring 15 is threadedly connected to the extension rod 13. Rotating the adjusting ring 15 allows the baffle 14 to move, thereby matching the recess at the clamping plate 5 to form the required length of the rubber strip, thus improving the cutting accuracy.

[0019] Among them, a support plate 16 is fixedly connected to one side of the baffle 14. The support plate 16 is at the same height as the clamping plate 5. By setting the support plate 16, the rubber strip can be supported (for some rubber strips with hardness).

[0020] One of the clamping plates 5 is rotatably connected to a support rod 17, which is movably inserted into the other clamping plate 5. A connecting ring 18 is threaded onto the support rod 17. By setting the support rod 17 and the connecting ring 18, the stability between the two clamping plates 5 can be improved.

[0021] The upper end of the fixed plate 1 is fixedly connected to the support frame 19, and the support frame 19 is fixedly connected to one side of the second motor. The output end of the second motor is fixedly connected to the guide wheel 20. The second motor drives the guide wheel 20 to rotate, which can guide the container sealing strip.

[0022] The guide wheel 20 has a horizontal plate 21 on its upper side, which is fixedly connected to the upper side of the limiting plate 2. A pressure rod 22 is threaded onto the horizontal plate 21, and a pressure ball 23 is rotatably embedded at the bottom end of the pressure rod 22. By setting the pressure rod 22 and the pressure ball 23, the guide wheel 20 can guide the container sealing strip.

[0023] Working principle: Rotate the bidirectional screw 4 according to the width of the container sealing strip, and rotate the connecting ring 18 so that one side of the connecting ring 18 contacts another clamping plate 5, causing the two clamping plates 5 to move relative to each other. Then, the concave side of the container sealing strip is stuck on the upper side of the clamping plate 5. At this time, the baffle 14 is extended according to the required cutting length, and the adjusting ring 15 and spring provide limit. Then, the guide wheel 20 rotates and cooperates with the pressure ball 23 to provide guidance so that one side of the container sealing strip falls on the support plate 16. Then, the first motor drives the first screw 9 to rotate, thereby causing the moving frame 10 to move relative to the two limit plates 2, and cooperates with the cutting blade to cut the container sealing strip, which can increase the stability of the sealing strip when the cutting wheel cuts.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
