Description

Technical Field

[0001] This utility model relates to the field of porous and fluffy materials, and more particularly to a cutting bed device. Background Technology

[0002] The core reason for cutting fluffy materials using a cutting machine is that the cutting machine positively optimizes fluffy materials. Most fluffy materials have a porous structure and usually have a large compression space. For example, a common sponge pad falls onto a conveyor belt assembly with negative pressure holes. The sponge pad is covered with a plastic film. Under negative pressure, the plastic film contracts, and the constraint force generated keeps the sponge in a compressed state. The compressed sponge forms a tight fit with the conveyor belt assembly, thus generating sufficient friction, and finally moves with the conveyor belt assembly.

[0003] However, during the experimental production of the prototype, the moment the blade pierced the plastic film, the cut allowed air circulation between the sponge pad and the outside world to be re-established, and the entire sponge pad instantly returned to its original fluffy state, making the original problem unsolvable. Utility Model Content

[0004] To solve the above problems, this utility model provides a cutting bed device that, while performing the cutting action, covers the damaged plastic film and reconstructs a new sealed space.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cutting bed device, comprising a cutting bed body, the cutting bed body having a conveying bristle brick assembly with negative pressure and a cutting head for cutting fluffy material, the fluffy material being disposed on the conveying bristle brick assembly, such that the plastic film covering the fluffy material is compressed and fixed by the tightening effect of the negative pressure, characterized in that it further comprises a secondary film covering mechanism for providing a new positioning film to the punctured plastic film, the positioning film and the negative pressure on the conveying bristle brick assembly reconstructing a new compression and fixation of the fluffy material.

[0006] The beneficial effects of this utility model are:

[0007] This invention proposes a method of re-coating to solve the problem of air leakage at the incision site. The secondary coating mechanism provides a new positioning film for the fluffy material. The positioning film covers the incision and isolates the air flow between the incision and the outside world. Under the influence of negative pressure, the air between the positioning film and the incision is extracted, and the fluffy material is recompressed and fixed through the positioning film.

[0008] Generally, the positioning film is laid flat on the plastic film and applies pressure evenly to the fluffy material through the attraction of negative pressure. This prevents the fluffy material from gathering in one area due to uneven force, avoids local thinning, and improves cutting accuracy.

[0009] The secondary laminating mechanism includes a laminating roller with an elastic band inside that is twisted into a thread to provide the rotational force required to tighten the positioning film. The twisted thread reset method exhibits extremely low space occupancy. It stores elastic potential energy inside the twisted thread, eliminating the need for additional relatively large reset components. The automatic return of the laminating roller after rotation is achieved solely by the torsional deformation of the elastic band itself. This not only satisfies the reliability of the reset function but also fits the usage environment where the internal space of the laminating roller is narrow and there are strict requirements for size. Furthermore, this design significantly reduces the overall size of the laminating roller.

[0010] Regarding the change process of the elastic band state, the forward direction of the clockwise rotation of the coating roller is defined as the direction of covering the fluffy material. The above-mentioned twisting reset means that the elastic band is always in the twisting state. During the forward movement, the twisting amplitude of the elastic band continues to increase, as shown in the figure. One end of the elastic band is fixed. During the forward movement, the other end of the elastic band rotates in the clockwise direction. The twisting and cohesion state presents a transition from the initial loose spiral to a tight and dense spiral shape. The continuous increase in twisting density causes the lines to gradually become thinner due to cohesion. At the same time, the overall tension of the positioning film increases synchronously.

[0011] The coating roller also includes a roller, an anti-rotation mechanism, and an adjusting shaft, fasteners, and positioning seats located inside the roller. The open structure on the fasteners provides positioning nodes when the elastic band is in a twisting posture. The elastic band passes around the open structure and connects to the positioning seats to form a ring. The fasteners are kept in a posture where their rotation axis is parallel to the rotation axis of the adjusting shaft, so that the rotation of the fasteners after connecting with the adjusting shaft causes the elastic band to twist. The anti-rotation end of the anti-rotation mechanism is in close contact with the adjusting shaft to maintain the rotation amplitude of the adjusting shaft. This adjusting shaft, which rotates separately from the roller, allows the fasteners to adjust the initial twist amplitude of the elastic band, ensuring that the tension on the positioning film can be properly adjusted, and the anti-rotation mechanism maintains the adjusted twist amplitude.

[0012] The secondary laminating mechanism also includes a laminating support, which provides positioning points for the positioning film. In the laminating environment, the positioning film roll is wrapped around the laminating roller, and the film head of the positioning film is fixed on the laminating support.

[0013] Both the cutter head and the secondary coating mechanism are mounted on the same moving beam. The synchronous change of their positions eliminates motion deviation and avoids relative positional offset between them.

[0014] In this embodiment, the secondary coating mechanism also includes a rocker arm and a cylinder. The rocker arm has a hinge point and is distributed at both ends of the moving beam and is rotatably connected to the moving beam. The cylinder is also set at both ends of the moving beam. The piston rod of the cylinder is connected to the outer end of the rocker arm. The rocking motion unfolds along a preset arc trajectory. In particular, when the cylinder is extended, the coating roller suspended on the rocker arm moves toward the positioning film.

[0015] The anti-rotation mechanism includes a positioning screw and a screw hole pre-set on the rocker arm. The outer end of the rocker arm is a hook. The adjusting shaft rests on the inner surface of the arc-shaped contour. The rocker arm supports the adjusted position of the coating roller. The coating shaft on the other end of the coating roller rests on another rocker arm.

[0016] The specific secondary lamination process is as follows:

[0017] S1, first adjust the rotating shaft to rotate counterclockwise so that the elastic band inside the coating roller forms a preset spiral state;

[0018] S2, the moving beam drives the coating roller to move towards the sponge, which increases the twisting density and the overall tension of the positioning film rises synchronously, eventually forming a flat state.

[0019] During the cutting process, negative pressure holes on the conveyor bristle brick assembly provide negative pressure, and the positioning membrane compresses and fixes the plastic film on the fluffy material.

[0020] The aforementioned fluffy materials are of various kinds, such as sponges.

[0021] In addition, end plates are provided at both ends of the roller to close the openings at both ends of the roller. Positioning seats are set on the end plates, and the end plates rotate with the rotation of the roller. The adjusting shaft is fitted with bearings, and the end plates are fitted on the bearings.

[0034] Please see Figure 1-12 As shown, a cutting bed device includes a cutting bed body 1, which has a negative pressure conveying bristle brick assembly 1a and a cutting head 1b for cutting fluffy material 4. The fluffy material 4 is disposed on the conveying bristle brick assembly 1a, such that a plastic film 5 covering the fluffy material 4 is compressed and fixed by the tightening effect of the negative pressure. The device is characterized by further including a secondary film covering mechanism 2 for providing a new positioning film 3 to the punctured plastic film 5. The positioning film 3 and the negative pressure on the conveying bristle brick assembly 1a reconstruct a new compression and fixation of the fluffy material 4.

[0035] The beneficial effects of this utility model are:

[0036] This invention proposes a method of re-coating to solve the problem of air leakage at the incision. The secondary coating mechanism 2 provides a new positioning film 3 for the fluffy material 4. The positioning film 3 covers the incision and isolates the air flow between the incision and the outside. Under the influence of negative pressure, the air between the positioning film 3 and the incision is extracted, and the fluffy material 4 is re-compressed and fixed through the positioning film 3.

[0037] Generally, the positioning film 3 is laid flat on the plastic film 5, and the negative pressure attraction effect is used to apply pressure evenly to the fluffy material 4 to prevent the fluffy material 4 from gathering in a certain area due to uneven force, thus avoiding the situation of local excessive thinness.

[0038] The secondary laminating mechanism 2 includes a laminating roller 21, which has an elastic band 21a in a twisted state to provide the rotational force required to tighten the positioning film 3. The twisted reset method exhibits extremely low space occupancy. It stores elastic potential energy inside the twisted wire, eliminating the need for additional relatively large reset components. The automatic return of the laminating roller 21 after rotation can be achieved solely by the torsional deformation of the elastic band 21a. This not only satisfies the reliability of the reset function but also fits the usage environment where the internal space of the laminating roller 21 is narrow and the volume requirements are stringent. Furthermore, this design significantly reduces the overall size of the laminating roller 21.

[0039] Regarding the change process of the state of elastic band 21a, as follows: Figure 5 As shown, the forward direction of the clockwise rotation of the coating roller 21 is defined as the direction of covering the fluffy material 4. The above-mentioned twisting is that the elastic band 21a is always in the twisting state. During the forward movement, the twisting amplitude of the elastic band 21a continues to increase. One end of the elastic band 21a is fixed. During the forward movement, the other end of the elastic band 21a rotates in the clockwise direction. The twisting and cohesion state is transformed from the initial loose spiral to a tight and dense spiral shape. The continuous increase in twisting density causes the lines to gradually become thinner due to cohesion. At the same time, the overall tension of the positioning film 3 increases synchronously.

[0040] The coating roller 21 also includes a roller 21b, an anti-rotation mechanism, and an adjusting shaft 21c, a fastener 21d, and a positioning seat 21e located within the roller 21b. The open structure on the fastener 21d serves as a positioning node when the elastic band 21a is in a twisting posture. The elastic band 21a bypasses the open structure (which is an opening) and connects to the positioning seat 21e to form a ring. The fastener 21d is kept in a posture where its rotation axis is parallel to the rotation axis of the adjusting shaft 21c, so that the rotation of the fastener 21d after connecting with the adjusting shaft 21c causes the elastic band 21a to twist. The anti-rotation end of the anti-rotation mechanism is in close contact with the adjusting shaft 21c to maintain the rotation amplitude of the adjusting shaft 21c. The adjusting shaft 21c, which rotates independently of the roller 21b, allows the fastener 21d to adjust the initial twist amplitude of the elastic band 21a, ensuring that the tension on the positioning film 3 can be properly adjusted, and the anti-rotation mechanism maintains the adjusted twist amplitude.

[0041] The secondary laminating mechanism 2 also includes a laminating bracket 21f, which provides positioning points for the positioning film 3. In the laminating environment, the roll of positioning film 3 is wrapped on the laminating roller 21, and the film head of positioning film 3 is fixed on the laminating bracket 21f.

[0042] Both the cutter head 1b and the secondary coating mechanism 2 are mounted on the same moving beam 3. The synchronous change of their positions eliminates the action deviation and avoids the offset of their relative positions.

[0043] In the embodiment, the secondary coating mechanism 2 also includes a rocker arm 22 and a cylinder 23. The rocker arm 22 is distributed at both ends of the moving beam 3 and is rotatably connected to the moving beam 3. The cylinder 23 is also set at both ends of the moving beam 3. The piston rod of the cylinder 23 is connected to the outer end of the rocker arm 22. The rocking motion unfolds along a preset arc trajectory. In particular, when the cylinder 23 is extended, the coating roller 21 suspended on the rocker arm 22 moves toward the positioning film 3.

[0044] The anti-rotation mechanism includes a positioning screw and a screw hole 21g pre-set on the rocker arm 22. The outer end of the rocker arm 22 is a hook. The adjusting shaft 21c rests on the inner surface 22a of the arc-shaped contour. The rocker arm 22 supports the adjusted position of the coating roller 21. The coating shaft 21j on the other end of the coating roller 21 rests on another rocker arm 22. The positioning screw passes through the screw hole 21g and is in close contact with the shaft end of the adjusting shaft 21c.

[0045] The specific secondary lamination process is as follows:

[0046] S1, see reference Figure 3 First, by adjusting the counterclockwise rotation of the rotating shaft 21c, the elastic band 21a inside the coating roller 21 forms a preset spiral state.

[0047] S2, the moving beam 3 drives the coating roller 21 to move towards the sponge. While increasing the twisting density, the overall tension of the positioning film 3 increases synchronously, eventually forming a flat state.

[0048] During the cutting process, the negative pressure hole on the conveying bristle brick assembly 1a provides negative pressure, and the positioning membrane 3 compresses and fixes the plastic film 5 on the fluffy material 4.

[0049] The aforementioned fluffy material 4 can be of various types, such as sponge.

[0050] In addition, end plates 21h are provided at both ends of roller 21b to close the openings at both ends of roller 21b. Positioning seat 21e is set on end plate 21h. End plate 21h rotates with the rotation of roller 21b. Adjustment shaft 21c is fitted with bearing 21i. End plate 21h is fitted on bearing 21i.

[0051] In this specific implementation, the cutting bed has a dual-station structure. A first coating roller is provided on the first crossbeam corresponding to the first cutter head, and a second coating roller is provided on the second crossbeam corresponding to the second cutter head. The first coating roller and the first coating support use one positioning film, and the second coating roller and the second coating support use another positioning film.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
