Description

Technical Field

[0001] This utility model relates to the field of foam board processing technology, and in particular to a biodegradable foam packaging board cutting mechanism. Background Technology

[0002] With increasingly stringent environmental protection requirements, biodegradable materials are finding wider application in the packaging industry. Biodegradable foam packaging boards, as a green packaging material, possess excellent cushioning properties and environmental friendliness, and are widely used for the transportation and protection of electronic products, precision instruments, and other products. In actual production processes, large pieces of foam boards often need to be precisely cut according to product dimensions to meet different packaging requirements.

[0003] Currently, traditional foam board cutting equipment mostly uses mechanical blades or fixed thermal cutting methods. Mechanical blade cutting easily causes compression deformation and burrs on the edges of the foam material, and is not suitable for soft, highly elastic materials such as biodegradable foam. Conventional thermal cutting equipment has difficulty effectively controlling the rebound and adhesion of the material after cutting, especially when making continuous horizontal cuts. The cut section is prone to closure of the cut due to elastic recoil or gravity, and the heating wire adheres to the foam melt, thus affecting the cutting quality and causing defects such as stringing and uneven cut surfaces. Utility Model Content

[0004] To overcome the shortcomings of continuous horizontal cutting, such as the cut section easily closing due to elastic retraction or gravity, and the heating wire sticking to the foam melt, thus affecting the cutting quality, the technical problem is to provide a biodegradable foam packaging board cutting mechanism.

[0005] The technical solution of this utility model is: a biodegradable foam packaging board cutting mechanism, including a cutting table, rodless cylinders, electric slide rails, a sliding frame, heating wires, a rotating drum, an adjustment mechanism, and a baffle. Rodless cylinders are installed on both sides of the top of the cutting table. Electric slide rails are installed on the moving parts of the two rodless cylinders. The sliding frame is connected between the sliding blocks of the two electric slide rails. The lower part of the sliding frame is connected to the heating wire. The lower part of the sliding blocks of the two electric slide rails is rotatably connected to the rotating drum. The rotating drum is located outside the heating wire. A baffle is connected between the outer walls of the two rotating drums. An adjustment mechanism for driving the rotating drum to rotate is installed on the sliding frame.

[0006] Furthermore, the central axis of the rotating drum is coaxial with the axis of the heating wire.

[0007] Furthermore, the thickness of the baffle is the same as the diameter of the heating wire.

[0008] Furthermore, the adjustment mechanism includes a large gear, a servo motor, and a small gear. The large gear is connected to the outside of one of the rotating drums, and the servo motor is installed on the side of the sliding frame near the large gear. The small gear is connected to the output shaft of the servo motor, and the small gear meshes with the large gear.

[0009] Furthermore, it also includes a frame and electric rollers. Two frames are connected to the top of the cutting table, with a gap between the two frames for the passage of heating wires and baffles. Electric rollers are installed at intervals on the frames.

[0010] Furthermore, it also includes guide seats, limit frames and fastening bolts. Guide seats are slidably connected to both ends of the cylinder barrel of the rodless cylinder on both sides. Fastening bolts are provided on the guide seats. The two guide seats on the same end are respectively provided with slots on opposite sides. A limit frame is detachably provided between the two slots.

[0011] The beneficial effects are as follows: 1. This utility model uses an electric heating wire for thermal cutting, which is suitable for soft materials such as biodegradable foam. It avoids the crushing and burr problems caused by mechanical cutting. During the horizontal cutting process, a rotatable baffle is set on one side of the electric heating wire to effectively prevent the cut part from re-contacting the high-temperature electric heating wire due to gravity or elastic rebound, thus preventing melting and adhesion, wire pulling and cut deformation, and ensuring that the cut surface is flat and smooth.

[0012] 2. By setting up frames with electric rollers on both sides of the cutting table, the foam board can be automatically conveyed and precisely positioned. At the same time, the adjustable limiting mechanism composed of guide seats, limit frames and fastening bolts can quickly adjust the limiting position according to the foam board of different widths, and can be firmly fixed by tightening the fastening bolts, effectively preventing the board from shifting during the cutting process and ensuring neat cut edges and accurate dimensions.

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] A biodegradable foam packaging board cutting mechanism, such as Figures 1-6 As shown, the device includes a cutting table 1, rodless cylinders 2, electric slide rails 3, a sliding frame 4, heating wires 5, a rotating drum 6, an adjustment mechanism, and a baffle 7. Rodless cylinders 2 are installed on both the front and rear sides of the top of the cutting table 1. Electric slide rails 3 are installed on the moving parts of both rodless cylinders 2, and the electric slide rails 3 are perpendicular to the rodless cylinders 2. The sliding frame 4 is connected between the sliding blocks of the two electric slide rails 3, and the electric slide rails 3 are used to drive the sliding frame 4 to move up and down. Heating wires 5 are connected to the lower part of the sliding frame 4, and the heating wires 5 are parallel to the cutting table 1. A rotating drum 6 is rotatably connected to the lower part of the sliding blocks of both electric slide rails 3, and the rotating drum 6 is located outside the heating wires 5. A baffle 7 is connected between the outer walls of the two rotating drums 6. An adjustment mechanism for driving the rotating drum 6 to rotate is installed at the lower part of the sliding frame 4.

[0022] The central axis of the rotating drum 6 is coaxial with the axis of the heating wire 5. The thickness of the baffle 7 is the same as the diameter of the heating wire 5 so that the gap formed by the baffle matches the slit. The adjustment mechanism includes a large gear 8, a servo motor 9 and a small gear 10. The large gear 8 is connected to the outside of one of the rotating drums 6. The servo motor 9 is installed on the side of the sliding frame 4 near the large gear 8. The output shaft of the servo motor 9 passes through the sliding frame 4. The small gear 10 is connected to the output shaft of the servo motor 9 and meshes with the large gear 8.

[0023] Furthermore, it also includes a frame 11 and an electric roller 12. Two frames 11 are connected to the top of the cutting table 1. A gap is left between the two frames 11 for the heating wire 5 and the baffle 7 to pass through. Electric rollers 12 are installed on the frames 11 at intervals. The roller surface of the electric roller 12 is in contact with the lower surface of the foam board 100.

[0024] In the initial state, the electric slide rail 3 is located at the middle of the stroke of the rodless cylinder 2, and the heating wire 5 is directly above the gap between the two frames 11, in standby mode. For vertical cutting, the heating wire 5 is first activated and heated to the preset working temperature. Then, the foam board 100 to be cut is placed on top of the two side frames 11, with its bottom surface in contact with the electric roller 12. The electric roller 12 is activated, driving the foam board 100 longitudinally. When it reaches the set cutting position, the electric roller 12 is stopped to achieve precise positioning. Next, the electric slide rail 3 is controlled to drive the sliding frame 4 and the heating wire 5 vertically downwards, allowing the high-temperature heating wire 5 to cut into the foam board 100, completing the transverse cut. During the cutting process, the baffle 7 descends synchronously with the heating wire 5 and passes through the newly formed slit, slightly opening the two cut sections of foam board 100 to prevent them from closing due to elastic rebound. After cutting, the electric slide rail 3 drives the sliding frame 4, heating wire 5, and baffle 7 to return to their initial height, ready for the next cut. When horizontal cutting of the foam board 100 is required, the rodless cylinder 2 is activated to move the electric slide rail 3 to the left, positioning the heating wire 5 above and to the left of the foam board 100. Then, the electric slide rail 3 is controlled to move the sliding frame 4 down to the cutting position. The servo motor 9 is activated to rotate the pinion 10, which in turn rotates the gear 8, positioning the baffle 7 to the left of the heating wire 5. Finally, the rodless cylinder 2 is activated to move the electric slide rail 3, sliding frame 4, and heating wire... 5 and baffle 7 move to the right. During the cutting process, the foam board 100 cut above tends to sag due to gravity. Baffle 7 can effectively block the cut part, preventing it from rebounding or re-contacting the high-temperature heating wire 5, preventing adhesion, wire pulling or cut deformation, thus ensuring a smooth and flat cutting surface. After the heating wire 5 has finished cutting from left to right, the servo motor 9 is started again to rotate, so that the baffle 7 rotates to the right side of the heating wire 5. Then the electric slide rail 3 is started to move down to the cutting position, and the rodless cylinder 2 is started to move from right to left. This process is repeated to horizontally cut the foam board 100.

[0025] Furthermore, it also includes guide seats 13, limit frames 14 and fastening bolts 15. Guide seats 13 are slidably connected to both ends of the outer cylinder barrel of the rodless cylinders 2 on both sides. Fastening bolts 15 are provided on the side of the guide seats 13. The two guide seats 13 at the same end are respectively provided with slots 16 on opposite sides. The upper part of the slots 16 is open. The limit frame 14 is detachably provided between the two slots 16.

[0026] When horizontally cutting the foam board 100, after placing the foam board 100 on the frame 11, loosen the fastening bolts 15, moving the fastening bolts 15 away from the cylinder of the rodless cylinder 2, pushing the guide seat 13 towards the foam board 100. After the limiting frame 14 contacts the side of the foam board, stop moving the guide seat 13, tighten the fastening bolts 15, and press the end of the fastening bolts 15 against the outer surface of the cylinder of the rodless cylinder 2 to fix the limiting frame 14. Through the synergistic action of the limiting frames 14 on both sides, the foam board 100 is accurately positioned and constrained laterally, effectively preventing the foam board 100 from shifting due to the pushing of the heating wire 5 during horizontal cutting, ensuring a stable cutting process and neat cut edges. If the foam board 100 is to be vertically cut, the limiting frame 14 can be pulled upward to remove it from the slot 16 of the guide seat 13, thereby releasing the lateral limitation on the foam board, and loosening the fastening bolts 15, pushing the guide seat 13 to move to the end of the rodless cylinder 2.

[0027] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
