Description

Technical Field

[0001] This utility model relates to the technical field of foam processing, and in particular to a raw material cutting device for foam processing. Background Technology

[0002] Foam is a material made by foaming plastic particles. Foam is categorized into various types, including PU foam, antistatic foam, conductive foam, EPE, antistatic EPE, CR, EVA, cross-linked PE, SBR, and EPDM. It possesses a range of characteristics such as elasticity, lightweight, rapid pressure-sensitive fixing, ease of use, flexibility, ultra-thinness, and reliable performance, making it widely used in packaging, furniture, automotive interiors, and sporting goods. To adapt foam to different application needs, it requires various processing and manufacturing methods, including but not limited to cutting, stamping, bonding, and thermoforming. Cutting devices, in particular, require manual removal of the cut foam from the equipment, resulting in low automation, significantly impacting the overall cutting speed, and posing safety hazards due to prolonged proximity to the machine. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a raw material cutting device for foam processing that improves production efficiency and safety through a stable material transport mechanism.

[0004] This utility model discloses a raw material cutting device for foam processing, comprising:

[0005] The body is independently fixed and includes a vertical plate, a base plate connected to it, and an end plate set at one end of it. The end plate has a channel for foam to pass through.

[0006] The cutting blade is movably installed in the channel and is driven to move up and down by a telescopic mechanism set in the end plate to cut the foam.

[0007] The feeding rod is rotatably installed between the vertical plates, with foam wrapped around its outer side;

[0008] The traction mechanism, installed on the side of the end plate near the feed bar, is used to pull the foam through the channel;

[0009] The guiding mechanism, installed between the feeding rod and the traction mechanism, is used to guide the foam.

[0010] The material collection mechanism is installed on the side of the end plate away from the traction mechanism to collect the finished products after cutting.

[0011] Furthermore, the traction mechanism includes a first traction roller and a second traction roller arranged parallel to each other at intervals. The first traction roller is driven to rotate by a first drive motor. The first drive motor is fixedly mounted on the upright plate by a first bracket. The upright plate is also provided with a first adjusting member for adjusting the distance between the first traction roller and the second traction roller.

[0012] Furthermore, the first adjusting component includes a first screw rod screwed to the upright plate, a first screw block screwed onto the first screw rod, the first screw block being rotatably connected to one end of the second traction roller, and a connecting block and a handle being respectively provided at both ends of the first screw rod, the connecting block being rotatably connected to the first screw rod and fixedly connected to the upright plate.

[0013] Furthermore, the guiding mechanism includes two symmetrically spaced guide plates, each with a groove on its facing surface that contacts the edge of the foam. The two guide plates are driven by a second adjusting member to move toward each other or toward each other.

[0014] Furthermore, the second adjusting component includes a second screw rod rotatably mounted between the vertical plates. The second screw rod is driven to rotate by a second drive motor.

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 5 As shown, the present invention provides a raw material cutting device for foam processing, comprising:

[0029] The body 1 is independently fixed and includes a vertical plate 11, a base plate 12 connected to it, and an end plate 13 set at one end of it. The end plate 13 has a channel 14 for the foam 2 to pass through.

[0030] The cutting blade 3 is movably installed in the channel 14 and is driven to move up and down by the telescopic mechanism 4 set in the end plate 13 to cut the foam 2.

[0031] The feeding rod 5 is rotatably installed between the vertical plates 11, and the foam 2 is wrapped around its outer side;

[0032] The traction mechanism 6 is installed on the side of the end plate 13 near the feeding rod 5 and is used to pull the foam 2 through the channel 14.

[0033] The guiding mechanism 7 is installed between the feeding rod 5 and the traction mechanism 6 and is used to guide the foam 2.

[0034] The material collection mechanism 8 is installed on the side of the end plate 13 away from the traction mechanism 6 to collect the finished products after cutting.

[0035] In this device, the main body 1 provides a stable structure to support other components, and the channel 14 on the end plate 13 provides space for the foam to pass through. The feeding rod 5 supports the foam material, and the traction mechanism 6 pulls the foam. The foam is wrapped around the feeding rod 5, and as the rod rotates, the foam gradually unfolds and is fed into the cutting area. The guiding mechanism 7 ensures that the foam maintains the correct path during transportation, preventing deviation or wrinkles that would affect the cutting quality. As the foam passes through the channel 14, the cutting blade 3 cuts the foam. The cutting action of the cutting blade 3 is driven by the telescopic mechanism 4, which may be a hydraulic, pneumatic, or electric system responsible for providing the force and motion required for cutting. The finished foam product is collected by the receiving mechanism 8 for subsequent processing or packaging. The design of this device takes automation and efficiency into account. The various components work together to allow the foam material to be continuously cut into the required size. By reducing manual intervention, the safety risks for operators are also reduced.

[0036] The traction mechanism 6 includes a first traction roller 61 and a second traction roller 62 arranged parallel to each other. The first traction roller 61 is driven to rotate by a first drive motor 63. The first drive motor 63 is fixedly mounted on the upright plate 11 by a first bracket 64. The upright plate 11 is also provided with a first adjusting member 65 for adjusting the distance between the first traction roller 61 and the second traction roller 62.

[0037] The traction mechanism 6 provides a stable clamping force through two traction rollers. The first traction roller 61 is driven to rotate by the first drive motor 63, which can precisely control the feeding speed of the foam material, thereby improving the cutting accuracy. The distance between the first traction roller 61 and the second traction roller 62 can be adjusted by the first adjusting member 65, which allows the equipment to handle foam materials of different thicknesses. This adjustability increases the flexibility of the equipment and makes it suitable for a wider range of application scenarios.

[0038] Preferably, the first adjusting member 65 includes a first screw 651 screwed to the upright plate 11, a first screw block 652 screwed onto the first screw 651, and the first screw block 652 rotatably connected to one end of the second traction roller 62. A connecting block 653 and a handle 654 are respectively provided at both ends of the first screw 651. The connecting block 653 is rotatably connected to the first screw 651 and fixedly connected to the upright plate 11. The connecting block 653 ensures that the first screw 651 will not shift during rotation, while allowing the screw to rotate freely for adjustment. When the first screw 651 is rotated, the first screw block 652 moves along the screw axis due to the thread. As the first screw block 652 moves, it drives the second traction roller 62 to move together, thereby changing the distance between the first traction roller 61 and the second traction roller 62. By rotating the handle 654, the operator can adjust the distance between the two traction rollers. This design is intuitive and easy to operate.

[0039] The guiding mechanism 7 includes two symmetrically spaced guide plates 71. Each guide plate 71 has a groove 72 on its facing surface that contacts the edge of the foam 2. The two guide plates 71 are driven by the second adjusting member 73 to move towards each other or away from each other. When the foam material passes between the two guide plates 71, the groove 72 can fit tightly against the edge of the foam, ensuring that the foam is smoothly transported along the predetermined path. The second adjusting member 73 drives the two guide plates 71 to move, which allows the operator to flexibly adjust the distance between the two guide plates 71 according to the actual width of the foam to accommodate foam materials of different sizes.

[0040] The preferred second adjusting component 73 includes a second screw 731 rotatably mounted between the vertical plates 11. The second screw 731 is driven to rotate by a second drive motor. The second screw 731 is provided with two sections of threads in opposite directions, which are symmetrically arranged about the center line of the second screw 731. Each section of thread is screwed with a second screw block 732, which is connected to the guide plate 71. When the second screw 731 is driven to rotate by the second drive motor, the two sections of threads will push the corresponding second screw blocks 732 to move simultaneously in two directions. This ensures that the distance between the two guide plates 71 can be adjusted synchronously, maintaining the symmetry and consistency of both sides, avoiding deviation problems that may be caused by unilateral movement, and improving the accuracy and reliability of adjustment.

[0041] Preferably, the second screw 731 is provided with guide rails 733 parallel to it on both sides, and each guide plate 71 is equipped with a slider 734 at the bottom. The slider 734 is slidably mounted on the guide rail 733. The guide rail 733 provides a stable linear motion path for the slider 734. Since the slider 734 is fixed on the guide plate 71 and slides with the guide rail 733, this ensures that the guide plate 71 slides smoothly under the screw drive, avoiding any unnecessary shaking or offset caused by the rotation of the screw, and ensuring the accurate transmission of foam material.

[0042] Preferably, each guide plate 71 is provided with a limiting plate 74 extending towards the feeding rod 5; when the foam material rotates and unfolds from the feeding rod 5, it ensures that the material always moves along the correct path during the transmission process, which helps to reduce cutting errors caused by material deviation.

[0043] The receiving mechanism 8 includes an inclined receiving plate 81 and a support bracket 82 supporting the receiving plate 81. Several casters 83 are installed at the bottom of the support bracket 82. Through the inclined design of the receiving plate 81, gravity is utilized to smoothly transfer the cut foam products from the cutting area to the receiving area. The support bracket 82 ensures that the receiving plate 81 maintains a stable tilt angle during operation. The casters 83 give the receiving mechanism 8 the flexibility to move. Operators can easily move the receiving mechanism 8 to different positions by pushing the support bracket 82, which is convenient for centralized collection or transfer of finished products.

[0044] This utility model discloses a raw material cutting device for foam processing. During operation, the foam material to be processed is first wound onto the feeding rod 5. The distance between the two guide plates 71 is adjusted using the second adjusting member 73 according to the width of the foam material to be processed, ensuring it meets the current processing requirements. The second drive motor is then started, driving the second screw 731 to rotate. Since the second screw 731 has two sections of threads in opposite directions, this causes the two second screw blocks 732 to move in opposite directions, thereby causing the two guide plates 71 to move closer or further apart, so that the groove 72 contacts the edge of the foam material. One end of the foam material is fed between the first traction roller 61 and the second traction roller 62. The distance between the first traction roller 61 and the second traction roller 62 is adjusted using the first adjusting member 65 according to the thickness of the foam material. The handle 654 is rotated to make the first screw 6... Rotating handle 654 determines whether the two traction rollers move closer or further apart based on the screw pitch and rotation direction. After adjustment, ensure handle 654 is locked in the current position. Start the first drive motor 63, which rotates the first traction roller 61 to smoothly drive the foam material into the equipment. When the foam material passes through channel 14, the telescopic mechanism 4 drives the cutting blade 3 to move up and down to precisely cut the foam. During the cutting process, the movement of the cutting blade is precisely controlled by the control system to ensure the quality and consistency of each cut. After cutting, the finished foam product slides naturally to the designated position through the inclined receiving plate 81. The angle of the receiving plate 81 can be adjusted as needed to optimize the collection efficiency of the finished product. If it is necessary to collect or transfer the finished product, the entire receiving mechanism 8 can be moved to the required position through the casters 83.

[0045] The present invention relates to a raw material cutting device for foam processing. Its installation method, connection method, or setting method are all common mechanical methods. As long as they can achieve their beneficial effects, they can be implemented.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
