Description

Technical Field

[0001] This utility model relates to the field of car seat cushion production technology, specifically a cutting device for car seat cushion production. Background Technology

[0002] A cutting device is a machine tool and cutting tool used to cut items into a specified shape. In the production of car seat cushions, the cushions need to be customized according to the actual size and shape of the seats in different car models. Through cutting, the raw materials can be cut into the size and shape that match the seats, ensuring that the cushions fit the seats closely and provide a comfortable riding experience. In the preparation of raw materials, there are usually large blocks of material. Through precise cutting, these materials can be used to maximize their utilization, reduce waste, and lower production costs. At the same time, the cut-off scraps can also be recycled and reused, further improving the utilization rate of materials.

[0003] When cutting the foam filling of car seat cushions, the foam is relatively soft and difficult to clamp and fix. Existing cutting devices tend to move the foam pieces to be processed during cutting, and the cutting pressure of the cutting head will make the cut uneven, affecting the cleanliness and aesthetics of the cut surface of the foam filling. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for the production of car seat cushions. The limiting plate directly presses the side of the material to prevent the material from sliding laterally during cutting and to ensure that the cut is straight. The elastic force of the second spring causes the card plate to automatically embed into the card slot, locking without additional operation, improving efficiency. At the same time, it absorbs cutting vibration and avoids loosening of the lock, while allowing easy reset when manually unlocked.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a cutting device for producing car seat cushions, comprising a cutting machine body with a cutting head, two limiting components on the top surface of the cutting machine body, and an auxiliary component on the cutting head. The limiting components include a rotating rod and two bases, which are mounted on the side walls of the cutting machine body. A limiting plate is movably arranged between the two bases, and a circular hole is opened on the limiting plate. The rotating rod is movably arranged inside the circular hole. An installation groove is opened on one side of the circular hole, and a second spring is installed inside the installation groove. A retaining plate is set at one end of the second spring. A spiral groove is opened on the rotating rod, and a retaining groove is opened inside the groove on one side of the rotating rod, with the retaining plate engaging inside the retaining groove.

[0007] Furthermore, a ring is installed on the top surface of the base, a bearing is installed inside the ring, and the inner ring of the bearing is installed on the rotating rod.

[0008] Furthermore, the auxiliary components include a top plate and a bottom plate, with the top plate threaded onto the cutting head, and a telescopic rod installed between the top plate and the bottom plate.

[0009] Furthermore, a first spring is installed on the outside of the telescopic rod, and mounting seats are installed at both ends of the telescopic rod and the first spring, respectively, on the top plate and the bottom plate.

[0010] Furthermore, the circular hole is connected to the mounting groove, and the retaining plate is movable inside the circular hole and the mounting groove to achieve telescopic movement.

[0011] This utility model has the following beneficial effects:

[0012] The base and ring of this utility model provide a stable support structure, ensuring the rigidity of the moving track of the limiting plate and avoiding deformation under force. The limiting plate directly presses against the side of the material to prevent the material from sliding laterally during cutting, ensuring a straight cut. The card plate automatically embeds into the card slot and locks without additional operation, improving efficiency.

[0013] The base plate of this utility model directly contacts the material surface, dispersing the cutting pressure, reducing local deformation or scratches on the material, and suppressing vibration and displacement. The first spring ensures that the cutter head is stably attached to the material during cutting, avoiding cutter jump or deviation. The telescopic rod and the first spring allow the base plate to float with the material thickness, protecting the material from overpressure damage.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for producing car seat cushions, including a cutting machine body 1 with a cutting head 2, two limiting components 3 on the top surface of the cutting machine body 1, and an auxiliary component 4 on the cutting head 2.

[0022] The limiting assembly 3 includes a rotating rod 304 and two bases 301. A ring 302 is mounted on the top surface of the base 301, and a bearing 303 is installed inside the ring 302. The inner ring of the bearing 303 is installed on the rotating rod 304. The bases 301 and the ring 302 provide a stable support structure to ensure the rigidity of the moving track of the limiting plate 305 and avoid deformation under force. The bearing 303 is embedded in the ring 302 to reduce the frictional resistance when the rotating rod 304 rotates, making the operation easier.

[0023] Two bases 301 are installed on the two side walls of the main body 1 of the cutting machine. A limiting plate 305 is movably set between the two bases 301. The limiting plate 305 directly presses the side of the material to prevent the material from sliding laterally during cutting and to ensure that the cut is straight.

[0024] The auxiliary component 4 includes a top plate 401 and a bottom plate 402. The bottom plate 402 directly contacts the material surface, disperses the cutting pressure, reduces local deformation or scratches of the material, and presses down to fix the material during cutting, further suppressing vibration and displacement.

[0025] The top plate 401 is threaded onto the cutting head 2. A telescopic rod 404 is provided between the top plate 401 and the bottom plate 402. A first spring 405 is provided on the outside of the telescopic rod 404. Mounting seats 403 are installed at both ends of the telescopic rod 404 and the first spring 405. The mounting seats 403 are respectively set on the top plate 401 and the bottom plate 402. The first spring 405 provides a constant downward pressure to ensure that the cutting head is stably attached to the material during cutting and to avoid cutting jumps or deviations. The telescopic rod 404 restricts the compression direction of the first spring 405 to prevent skewing, while allowing the bottom plate 402 to float with the material thickness to protect the material from overpressure damage.

[0026] A circular hole 6 is provided on the limiting plate 305, and the rotating rod 304 is movably set inside the circular hole 6. An installation groove 7 is provided on one side of the circular hole 6. A second spring 8 is installed inside the installation groove 7. A locking plate 9 is provided at one end of the second spring 8. The locking plate 9 is automatically inserted into the locking groove 5 by the elastic force of the second spring 8, locking without additional operation, improving efficiency, absorbing cutting vibration, preventing loosening of the locking, and allowing easy reset when manually unlocked.

[0027] The rotating rod 304 has a spiral groove. A slot 5 is formed inside the groove on one side of the rotating rod 304. The locking plate 9 is fitted inside the slot 5. The spiral groove of the rotating rod 304 converts the rotational motion into the linear movement of the limiting plate 305, realizing precise lateral adjustment. The slot 5 and the locking plate 9 cooperate to achieve automatic locking, preventing the limiting plate 305 from being accidentally displaced during processing and ensuring fixation reliability. The round hole 6 is connected to the mounting groove 7. The locking plate 9 is movable inside the round hole 6 and the mounting groove 7 to realize extension and retraction.

[0028] When using the cutting device to cut car seat cushions, the seat cushion material to be cut is laid flat on the top surface of the cutting machine body 1 and placed between two limiting components 3. By rotating the rotating rod 304 on the limiting plate 305, the limiting plate 305 moves axially along the ring 302 of the base 301, pushing the limiting plate 305 closer to or further away from the side of the seat cushion material to achieve precise fixation of the lateral position. When the rotating rod 304 rotates, its spiral groove slides and engages with the clamping plate 9. When the limiting plate 305 moves to the target position, the clamping plate 9 is inserted into the clamping groove 5 of the rotating rod 304 under the elastic force of the second spring 8, completing the automatic locking of the limiting plate 305. The top plate 401 and the bottom plate 402 are adjusted by the threaded engagement. The spacing between the compression telescopic rod 404 and the first spring 405 ensures that the base plate 402 is in close contact with the surface of the seat cushion material, thus ensuring the stability of the cutter head 2 during the cutting process. At the same time, it allows the base plate 402 to adjust its height slightly according to the material thickness, avoiding excessive pressure damage to the material. The main body of the cutting machine 1 is started, and the cutting cutter head 2 is driven to move downward in the vertical direction. After the cutting cutter head 2 penetrates the material, it returns to its original position. The first spring 405 pushes the base plate 402 back to its initial position, ready for the next cut. The rotating rod 304 is rotated in the opposite direction to disengage the clamping plate 9 from the clamping slot 5. The limiting plate 305 moves freely to adapt to materials of different sizes. The above steps are repeated. Through the synergistic effect of the limiting component 3 and the auxiliary component 4, efficient and precise cutting of batch seat cushion materials is achieved.
