Description

Technical Field

[0001] This utility model relates to the field of foam cutting technology, and in particular to a high-performance foam cutting machine with adjustable width. Background Technology

[0002] Foam products are frequently used in daily life, requiring them to be cut into various shapes. Currently, the most common method for foam cutting is using a foam cutter equipped with a heated wire. A foam cutter typically consists of left and right cutting frames, with the two ends of the heated wire fixed to wire holders on these frames. A worktable is located between the left and right cutting frames. When using a foam cutter, the foam material to be cut is first placed on the worktable, and then the heated wire on the cutting frame is moved to cut the foam.

[0003] Existing foam cutting machines typically have fixed left and right cutting frames, and the distance between them cannot be flexibly adjusted according to the width of the material to be cut. This means that when cutting foam materials of different widths, operators often need to change to different sizes of cutting equipment. This requires factories to equip themselves with various sizes of equipment, increasing fixed asset investment, or they can only cut smaller products on larger equipment, leading to increased energy consumption and production costs, while also severely impacting cutting efficiency. Furthermore, the width of the worktable is also fixed. When the width of the foam material to be cut exceeds the worktable, the material edges cannot be stably supported, easily causing material deviation and wobbling during cutting, resulting in decreased cutting accuracy and even producing defective products. Utility Model Content

[0004] The purpose of this invention is to provide a high-performance foam cutting machine with adjustable width to solve the technical problems existing in the prior art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A high-performance foam cutting machine with adjustable width includes two opposing cutting frames, a detachable tabletop positioned between the two cutting frames, and heating wires with their ends respectively attached to the two cutting frames.

[0018] like Figure 1-7As shown, this utility model provides a high-performance foam cutting machine with adjustable width, including two opposing cutting frames 10, which are mirror-symmetrically distributed, with the left cutting frame on the left and the right cutting frame on the right. A detachable table 20 is provided between the left and right cutting frames for placing the foam material to be cut. The two ends of an electric heating wire are respectively hung on the left and right cutting frames. By moving the electric heating wire, the foam material placed on the detachable table 20 can be cut. The bottom of the cutting frame 10 is provided with a slider 40 and a fixing device. The slider 40 can slide on the slide rail 30 to change the relative position between the left and right cutting frames to adjust the width and adapt to foam materials of different widths. After adjusting to a suitable width, the position of the cutting frame 10 can be fixed by the fixing device. The detachable tabletop 20 includes a main tabletop 21, a first side tabletop 22, and a second side tabletop 23. A slider 40 and a locking element 50 are provided at the bottom of the main tabletop 21, the first side tabletop 22, and the second side tabletop 23. The slider 40 can also slide on the slide rail 30 to realize the combination and separation of the three, so as to provide stable support for foam materials of different widths. After the positions of the three are adjusted, their positions can be locked by the locking element 50 to prevent the tabletop from shifting during the cutting process.

[0019] The cutting frame 10 includes a support frame 11, a movable frame 12, a lifting plate 13, and a rotatable wire hanging frame 14. The support frame 11 is a frame structure composed of aluminum alloy profiles, consisting of a base frame 111 and a vertical frame 112 fixedly connected. The base frame 111 is horizontally positioned, and the vertical frame 112 is vertically fixed to the base frame 111. A reinforcing plate 113 is connected to the vertical connection between the base frame 111 and the vertical frame 112 to improve structural stability. A support frame base plate 114 is provided at the bottom of the base frame 111, and the support frame base plate 114 is fixed to the bottom of the base frame 111 by bolts and fixedly connected to the slider 40. Two transverse guide rails are provided on the vertical frame 112, and the movable frame 12 is connected via... A sliding member fitted on the horizontal guide rail is slidably connected to the vertical frame 112. Driven by a motor and belt, the movable frame 12 can slide horizontally along the vertical frame 112, thereby adjusting the lateral position of the heating wire. A vertical guide rail is provided on the movable frame 12. The lifting plate 13 is connected to the vertical guide rail through the sliding member. Driven by a motor and belt, the lifting plate 13 can slide up and down along the vertical guide rail, thereby realizing the up and down movement of the heating wire. The rotatable wire hanging frame 14 is installed in the middle of the lifting plate 13 through a bearing and a rotating shaft. It can rotate around the rotating shaft, which facilitates the adjustment of the cutting direction of the heating wire. A wire hanging spring is provided on the rotatable wire hanging frame 14, and the heating wire is hung on the wire hanging spring. Furthermore, a fixing device is fixedly connected to the support base plate 114 of the left cutting frame. The fixing device is a locking member 50, which locks the position of the left cutting frame. The fixing device of the right cutting frame is a fastening cylinder 60, which fixes the position of the right cutting frame. The fastening cylinder 60 can also pull the right cutting frame slightly to tighten the heating wire.

[0020] The main tabletop 21 of the detachable tabletop 20 includes a table plate 211 and a table plate frame 212. The table plate 211 is made of fireproof plastic board and is fixed to the table plate frame 212 with countersunk bolts. The table plate frame 212 is a rectangular frame structure composed of aluminum alloy profiles. A table plate base plate 213 and a locking seat plate 214 are provided at the bottom of the table plate frame 212. The table plate base plate 213 is fixed to the bottom of the table plate frame 212 with bolts and is fixedly connected to the slider 40. The locking seat plate 214 is fixed to the bottom of the table plate frame 212 with a double-hole slider 40 nut and is fixedly connected to the locking member 50 with bolts. The first side tabletop 22 and the second side tabletop 23 have the same structure as the main tabletop 21. They are slidably arranged on the left and right sides of the main tabletop 21 by sliders 40 and locked in position by locking member 50.

[0021] The slide rail 30 consists of two parallel cylindrical linear guide rails. A slide rail base 31 is integrally formed and connected to the lower part of the slide rail 30. The slide rail base 31 fixes the slide rail 30 to the slide rail mounting beam 32 with bolts. Four connecting beams 33 are arranged laterally between the two slide rail mounting beams 32. Foot 34 is installed at the position corresponding to the connecting beams 33 below the slide rail mounting beam 32. The height of the foot 34 is adjustable, with an adjustment range of 0-50mm. The slide rail limiting block 35 is fixed to both ends of the slide rail 30 with hexagonal bolts, which can effectively avoid the risk of derailment when the cutting frame 10 moves to the limit position.

[0022] The slider 40 includes a slider body 41 and an internally embedded open-type linear bearing 42. The inner ring of the linear bearing 42 is provided with multiple sets of balls, and the outer ring is interference-fitted with the slider body 41. The linear bearing 42 adopts a "C"-shaped opening design, is sleeved on the slide rail 30 and can slide on it, and the opening is used to avoid the slide rail base 31. The top of the slider 40 is fixedly connected to the support frame base plate 114 of the cutting frame 10 and the table frame base plate 213 of the table by bolts.

[0023] The locking component 50 includes a locking block 51, a plumb bob 52, and a copper washer 53. The locking block 51 is a block structure, and its top is fixedly connected to the support frame base plate 114 of the left cutting frame and the locking seat plate 214 of the table by bolts. Its lower part has a "C"-shaped groove that matches the outer diameter of the slide rail 30. The locking block 51 is fitted onto the slide rail 30 through the "C"-shaped groove. A threaded hole is opened on one side of the locking block 51. The plumb bob 52 passes through the threaded hole of the locking block 51 and abuts against the copper washer 53. When the plumb bob 52 is tightened, the copper washer 53 is squeezed and tightly adheres to the surface of the slide rail 30. The locking block 51 and the slide rail 30 are fixed relative to each other by friction, thereby realizing the position locking of the cutting frame 10 or the table. When the position needs to be adjusted, the plumb bob 52 is loosened in the opposite direction. The copper washer 53 is separated from the surface of the slide rail 30, and the slider 40 can then drive the left cutting frame or the table to slide freely along the slide rail 30.

[0024] The cylinder body of the fastening cylinder 60 is fixed to the rightmost connecting beam 33 via a cylinder mounting seat. The end of its piston rod is hinged to a connector fixed to the lower part of the right cutting frame base 111 via a Y-type joint. When the piston rod extends or retracts, it can drive the right cutting frame to move along the slide rail 30. When the piston rod stops extending or retracting, it can fix the position of the right cutting frame to ensure its stability. If it is necessary to further tighten the heating wire, the piston rod can be slightly retracted through the cylinder control system, and the heating wire can be tightened by the slight displacement of the right cutting frame, ensuring that the heating wire is always taut during the cutting process and improving the cutting accuracy.

[0025] In use, the operator can first loosen the locking parts 50 of the left cutting frame and the detachable table 20 according to the width of the foam material to be cut. Then, push the left cutting frame along the slide rail 30 to the appropriate position and tighten the locking parts 50 again to lock it in place. The right cutting frame remains fixed under the pulling force of the cylinder. Next, slide the first side table 22 and the second side table 23 to combine with the main table 21 to form a support plane suitable for the width of the foam material to be cut. After adjustment, tighten their respective locking parts 50. Place the foam material to be cut on the detachable table 20. According to the cutting requirements, adjust the lateral position of the heating wire by sliding the moving frame 12 along the horizontal guide rail. Start the equipment to heat the heating wire. Move the heating wire along the vertical guide rail using the lifting plate 13 to contact the foam material and cut it. During the cutting process, since the spacing of the cutting frames 10 and the width of the table are adjusted according to the material size, and each component is fixed by the locking parts 50 or the fastening cylinder 60, material deviation and equipment shaking can be effectively avoided, ensuring cutting accuracy and stability. After cutting is complete, turn off the equipment.
