Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane foam slitting, in particular to a polyurethane foam slitting machine. Background Art

[0002] The polyurethane foam obtained by foaming is mainly a rectangular parallelepiped. In order to meet different production needs, the semi-finished product must be die-cut to obtain multiple smaller finished products. The existing slitting machine mainly includes a frame and a conveyor belt, and the conveyor belt is connected to the frame through a conveyor roller. A support seat is slidably connected to the frame, and a cutter is provided on the support seat, and the cutter is placed horizontally above the conveyor belt. However, during the reciprocating movement of the cutter, due to the large friction between the cutter and the polyurethane foam, the polyurethane foam is easily offset along the width direction of the conveyor belt, thereby affecting the slitting quality. If the existing slitting machine wants to solve the above problem, the user needs to press the upper end surface of the polyurethane foam by hand, and then cut the polyurethane foam by pressing the cutter. In the actual operation process, it is often easy for the cutter to cut the palm. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model provides a polyurethane foam slitting machine, which solves the problem that the prior slitting machine has poor control effect on the state of the polyurethane foam during cutting.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a polyurethane foam slitting machine, comprising a support frame, a slitting plate mounted on the support frame, a cutting head for cutting polyurethane foam mounted on an extension track of the slitting plate, a pushing device mounted on a plate extending toward the cutting head from a feed end of the slitting plate, and an alignment assembly disposed on the slitting plate after output from the cutting head for pushing the polyurethane foam toward a single position;

[0006] The pushing device extends from the side fence on one side of the cutting head to the other side fence, and includes an arc-shaped guide plate installed on the side wall of the side fence. The arc-shaped guide plate is installed with several rollers along its own structural extension direction to assist the movement of the polyurethane foam.

[0007] In one embodiment, the spacing between the two side rails 1 is smaller than the spacing between the two side rails 2, and the alignment assembly is provided on the side rail 2, which is provided with a compensation plate installed on the front end of the side rail 2 to compensate for the position difference between the side rail 1 and the side rail 2, and the front end of the compensation plate is installed with a compression spring connected to the side wall of the side rail 2, and the push plate acting on the compensation plate is installed on the side rail 2 located at the rear end;

[0008] The compensation plate is connected to the arc-shaped material guide plate.

[0009] In one embodiment, one side of the arc-shaped material guide plate is installed on sidebar one and ends on sidebar two. The material guide channel surrounded by the arc-shaped material guide plate and sidebar one or sidebar two reaches a minimum value at the lower end of the cutting head, and a cutting groove adapted to the cutting head is provided on the arc-shaped material guide plate.

[0014] Beneficial effects:

[0015] In the technical solution disclosed by the present invention, first, during the transportation to the cutting head, the width of the transportation channel is gradually reduced, friction is generated on its side walls, and then the friction between it and the cutting knife is balanced, so that it can move smoothly on the conveyor belt. On the other hand, after the cutting is completed, the width of the transportation channel is expanded, so that the polyurethane foam that has been cut can be quickly separated from the operating range of the cutting head under the action of the roller, thereby effectively increasing the output efficiency of the polyurethane foam after cutting.

[0016] By arranging an alignment component on the second sidebar of the utility model, the polyurethane foam cut by the cutting head is aligned so that it is located at the same output port when it leaves the slitting plate, which is convenient for subsequent external machinery to take over.

[0023] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Figure 1-Figure 4 This is one embodiment of the present invention, addressing the specific problem that the polyurethane foam obtained by foaming is primarily rectangular. To meet different production needs, the semi-finished product must be die-cut to obtain multiple smaller finished products. Existing slitting machines, due to the high friction between the cutter and the polyurethane foam, easily cause the polyurethane foam to shift along the width of the conveyor belt, thereby affecting the slitting quality. To address this problem, existing slitting machines require the user to manually press the upper end surface of the polyurethane foam before cutting the polyurethane foam with the cutter. During actual operation, the cutter often cuts the palm. To address the aforementioned problems caused by the polyurethane foam cutting process, this solution describes a polyurethane foam slitting machine. First, during the process of transporting the polyurethane foam to the cutting head 3, the width of the transport channel is gradually reduced, generating friction on the sidewalls, thereby balancing the friction between the sidewalls and the cutter, thereby enabling smooth movement on the conveyor belt. Second, after cutting, the width of the transport channel is expanded, thereby increasing the ability of the cut polyurethane foam to quickly escape the operating range of the cutting head 3 under the action of the roller 42, effectively increasing the output efficiency of the cut polyurethane foam.

[0026] The polyurethane foam slitting machine described herein specifically comprises a support frame 1, on which a slitting plate 2 is installed, and a conveyor belt is provided on the slitting plate 2. The polyurethane foam moves from one end to the other end of the slitting plate 2 driven by the conveyor belt, and a cutting head 3 for cutting the polyurethane foam is installed on the extension track of the slitting plate 2. A pushing device 4 is installed on the plate body extending toward the cutting head 3 at the feeding end of the slitting plate 2. The pushing device 4 controls the width of the material feeding channel to limit the displacement of the polyurethane foam during the cutting process. After being output along the cutting head 3, an alignment component 5 is provided on the slitting plate 2 for pushing the polyurethane foam to a single position, so that the polyurethane foam is located at the same output port when it is driven by the conveyor belt to be taken over by subsequent external machinery.

[0027] Sidebars 1 6 and 2 7 are provided on the left and right ends of the slitting plate 2 with the cutting head 3 as the center line. The cutting head 3 is specifically installed on sidebar 1 6. The cutting head 3 includes a tool holder 31 installed on sidebar 1 6. The tool holder 31 is equipped with a retractable blade 32 for cutting polyurethane foam. The retractable blade 32 can be driven by a cylinder to achieve the purpose of up and down movement. Sidebars 1 6 and 2 7 are symmetrically arranged at the edges of the slitting plate 2. The spacing between the two sidebars 1 6 is smaller than the spacing between the two sidebars 2 7. The spacing between the two sidebars 1 6 and the two sidebars 2 7 facilitates the installation of the alignment component 5. When there is no force, the sidebar 2 7 can be level with the sidebar 1 6 under the compensation of the alignment component 5. This increases the stability of the polyurethane foam under the drive belt, ensuring that it is always stable without scratching the structure, thereby increasing the stability of the transmission.

[0028] The ejection device 4 extends from one side of the cutting head 3 to the other side. It includes an arcuate guide plate 41 mounted on the sidewall of the sidebar. Along its extension, the arcuate guide plate 41 is equipped with several rollers 42 to assist in the movement of the polyurethane foam. One side of the arcuate guide plate 41 is attached to sidebar 1 6 and terminates at sidebar 2 7. The material guide channel enclosed by the arcuate guide plate 41 and either sidebar 1 6 or sidebar 2 7 reaches its minimum at the lower end of the cutting head 3. The arcuate guide plate 41 is provided with a cutting slot 43 adapted for the cutting head 3.

[0029] The alignment component 5 is arranged on the siderail 2 7, and is provided with a compensation plate 51 installed on the front end fence 2 to compensate for the position difference between the siderail 1 6 and the siderail 2 7. Half of the difference between the distance between the two siderails 1 6 and the distance between the two siderails 2 7 is equal to the length of the compensation plate 51 and the compression spring 52. When the compression spring 52 is not under force, the side plate of the compensation plate 51 is horizontal with the side plate of the siderail 1 6. The compensation plate 51 is connected to the arc-shaped guide plate 41. The front end of the compensation plate 51 is equipped with a compression spring 52 connected to the side wall of the side fence 2 7. The compensation plate 51 is provided with a pressure sensor at the position where the compression spring 52 is installed. The push plate 53 acting on the compensation plate 51 is installed on the side fence 2 at the rear end. The width of the push plate 53 is equal to the sum of the lengths of the compression spring 52 and the compensation plate 51. A load-bearing rod is installed on the support frame 1. A driving bin 54 for driving the push plate 53 to move toward the compensation plate 51 is installed between the load-bearing rod and the side fence 2 7. A cylinder connected to the push plate 53 is installed in the drive bin 54. Under the action of the cylinder, the push plate 53 is pushed toward the compensation plate The compensation plate 51 moves closer to the direction of the compensation plate 51. When in use, the push plate 53 is acted upon by the cylinder to move toward the compensation plate 51, and pushes the polyurethane foam compensation plate 51 that does not fit the compensation plate 51 on the conveyor belt. When the pressure sensor of the compensation plate 51 is pushed by the compression spring 52, the cylinder retracts. At this time, the compensation plate 51 will return to its original shape under the action of the compression exploration lane and push the polyurethane foam toward the push plate 53. As a result, the polyurethane foam produces a follow-up motion and has the same movement distance as the compensation plate 51. After the compensation plate 51 returns to its original shape, the purpose of fitting the polyurethane foam is achieved, that is, the purpose of discharging the material at the same position is achieved.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
