[0048] The pearl cotton grooving machine of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0049] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0050] This embodiment discloses a grooving machine for EPE foam. By adopting a multi-directionally adjustable, purely mechanical grooving structure suitable for various specifications of EPE foam, it solves the problems of existing technologies such as the generation of dioxin harmful gases when cutting EPE foam with a hot knife, the hot knife being prone to sticking, unsuitability for processing large batches of high-precision products, and the limitation of electric heating energy by electricity. See the following for details.

[0051] To achieve the above objectives, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3It mainly includes a main frame 1, on which a feeding part 2 is provided. The upper part of the feeding part 2 is provided with a grooving part 3. Grooving is achieved by feeding material from the feeding part 2 to the grooving part 3. The feeding part 2 is slidably disposed on the main frame 1. The grooving part 3 is mounted above the feeding part 2. The grooving part 3 can be slidably adjusted relative to the main frame 1 along the X-axis and Y-axis. The grooving position of the grooving part 3 can be adjusted relative to the feeding part 2.

[0052] In this embodiment, the feeding section 2 is used to carry and push the pearl cotton 4 material to be processed. A grooving section 3 is provided above the feeding section 2. The material is fed from the feeding section 2 to the grooving section 3 to complete the continuous grooving operation of the pearl cotton 4. The feeding section 2 is slidably mounted on the main frame 1 and can reciprocate along a set direction to achieve stable feeding. The grooving section 3 is mounted above the feeding section 2 and can slide and adjust relative to the main frame 1 in the X and Y axes, thereby enabling grooving of pearl cotton of different specifications.

[0053] Furthermore, the grooving part 3 can be adjusted relative to the feeding part 2, so that the grooving point can be flexibly set according to the actual processing requirements, making it more practical and applicable.

[0054] See Figure 1 , Figure 3 The feeding part 2 includes a feeding slide rail 201 and a feeding push plate 202. The feeding slide rail 201 is located on the top of the main frame 1. A slider 211 is provided on the feeding slide rail 201. The feeding push plate 202 is located on the slider 211. The feeding push plate 202 is slidably located on the feeding slide rail 201 via the slider 211.

[0055] In this embodiment, the feeding slide rail 201 is disposed on the top of the main frame 1 to provide a straight sliding path for the feeding pusher plate. The slider 211 is mounted on the feeding slide rail 201 and can move on the slide rail. The feeding pusher plate 202 is fixedly mounted above the slider 211 to carry and push the pearl cotton 4 material to be processed.

[0056] By pushing the feeding push plate 202, it slides along the feeding slide rail 201. The slider 211 cooperates with the slide rail 201 to send the pearl cotton 4 placed on the feeding push plate 202 to the bottom of the grooving section 3 for the next grooving operation.

[0057] After completing one grooving cycle, remove the grooved pearl cotton and pull the sliding feed pusher 202 back to the starting position to prepare for the next round of feeding.

[0058] To achieve grooving of the pearl cotton 4 fed into the grooving section 3, see [reference needed]. Figure 2 , Figure 3 , Figure 6The slotted part 3 includes an adjustment support unit 301, a truss 302 and a slotting unit 303. The truss 302 is mounted on the main frame 1 via the adjustment support unit 301, and the slotting unit 303 is mounted on the truss 302.

[0059] In this embodiment, the grooving section 3 is located entirely above the feeding section 2 and is used to groove the pearl cotton. Adjustable support units 301 are installed on both sides of the upper part of the main frame 1, at both ends of the trellis 302, to support and adjust the height and horizontal position of the trellis, achieving multi-directional adjustment. The trellis 302 is mounted on top of the adjustable support units 301, and the grooving unit is installed on it, providing a sliding adjustment and mounting platform for the grooving unit. The grooving unit 303 is slidably and positionably mounted on the trellis 302, and its position can be adjusted as needed.

[0060] See Figure 3 , Figure 6 The adjusting support unit 301 is symmetrically arranged at both ends of the truss 302. The adjusting support unit 301 includes a support frame 311 and a threaded screw 312. The threaded screw 312 is longitudinally rotatably disposed inside the support frame 311. A threaded sleeve 313 is provided on the threaded screw 312, and a displacement frame 314 is provided outside the threaded sleeve 313. The displacement frame 314 is fixedly connected to the end of the truss 302. After the top of the threaded screw 312 rotates and passes through the top of the support frame 311, an adjusting handwheel 315 is provided at its top.

[0061] In this embodiment, by rotating the adjustment handwheel 315, the threaded screw 312 is driven to rotate. The rotation of the threaded screw 312 drives the threaded sleeve 313 to move up and down linearly. The threaded sleeve 313 drives the displacement frame 314 to move up and down together. Since the displacement frame 314 is fixedly connected to the end of the truss 302, the entire truss 302 rises and falls accordingly, thereby realizing the height adjustment of the truss 302. At the same time, the height of the grooving unit 303 from the feeding push plate 202 is adjusted, thereby precisely controlling the grooving depth.

[0062] See Figure 1 , Figure 3 The support frame 311 has a horizontal sliding plate 317 at its bottom, and the main frame 1 has a horizontal slide rail 318 corresponding to the horizontal sliding plate 317. The horizontal sliding plate 317 is slidably mounted on the horizontal slide rail 318.

[0063] In this embodiment, the support frame 311 is slidably mounted on the transverse slide rail 318 on the main frame 1 via the transverse sliding plate 317 at the bottom. When it is necessary to adjust the position of the slotted part 3 relative to the main frame in the X-axis direction, the operator can manually adjust the support unit 301 to drive the entire slotted part 3 to move laterally along the transverse slide rail 318. Through the above structure, the landing point of the tool in the material width direction can be flexibly adjusted according to the required slotting position, thereby meeting the processing requirements of products of different sizes.

[0064] Additionally, it should be noted that in actual use, a stop bolt can be installed on the transverse slide plate 317. By tightening the stop bolt, the transverse slide rail 318 is pressed against it, thereby achieving the positioning of the transverse slide plate 317.

[0065] See Figure 2 , Figure 4 , Figure 5 The trellis 302 is a trellis 302 with a sliding groove, and multiple sets of slotting units 303 are provided, all of which are slidable and can be positioned on the trellis 302.

[0066] Specifically, the grooving unit 303 includes a sliding member 331, a fixing block 332, and a tool holder 333. The sliding member 331 is slidably disposed at the groove of the frame 302. The fixing block 332 is fixedly disposed on the outside of the sliding member 331. The tool holder 333 is detachably disposed on both sides of the fixing block 332. Each tool holder 333 is provided with a blade 334.

[0067] In this embodiment, the truss 302 is provided with a sliding groove, allowing multiple sets of grooving units 303 to slide freely on it. In actual use, each grooving unit 303 can be adjusted and locked in any position according to the required number of grooves, spacing, and other requirements. With the above structure, this device can complete grooving operations at multiple different positions at once, significantly improving processing efficiency.

[0068] Each slotting unit consists of three parts: a sliding component 331, a fixing block 332, and a tool holder 333. It is easy to assemble, replace, or maintain. The tool holder 333 is a detachable structure, which supports quick replacement of blades 334 with different shapes or angles.

[0069] Furthermore, in the multiple sets of grooving units 303, the fixing block 332 of the middle grooving unit 303 has beveled surfaces at its two bottom corners. The tool holder 333 is symmetrically mounted against the beveled surfaces, and the blade 334 mounted on the tool holder 333 cuts a 90° angled groove. The tool holder 333 is mounted on the outer beveled surface of the fixing block 332 at the bottom of the left-end grooving unit 303, and the fixing block 332 of the right-end grooving unit 303 has a beveled surface at one corner and a right angle at the other corner. The tool holder 333 is mounted against its beveled surface and right angled longitudinal edge, respectively. The multiple sets of grooving units 303 can be detached from the frame 302, thereby adjusting the position of the multiple sets of grooving units 303.

[0070] In this embodiment, the bottom two corners of the fixing block of the grooving unit located in the middle are beveled, and the tool holders are symmetrically fitted together. After the blades are installed, a 90° included-angle groove (V-shaped groove) is formed, which is suitable for processing structures such as butt joints, folds, or embeddings. The tool holder 333 is installed on the outer bevel of the bottom of the fixing block 332 of the grooving unit 303 located at the left end. The bottom corner of the fixing block of the grooving unit located at the right end is beveled, and the other corner is a right angle. The tool holders are fitted together with the beveled surface and the right angle longitudinal edge, respectively, which can realize the processing of irregular grooves such as single-sided bevel cutting, V-shaped groove opening, or L-shaped groove opening, and is used for edge transition cutting or irregular splicing.

[0071] The entire slotted unit 303 can be removed from the truss 302, allowing for reconfiguration and installation according to different product requirements, thus enhancing the versatility and expandability of the equipment. Example

[0072] The similarities to the above embodiments will not be repeated, the differences are as follows:

[0073] See Figure 1 , Figure 2 The slider 211 is mounted on the bottom of the feeding push plate 202 via a channel steel 212, and a push-pull handle 213 is mounted on the channel steel 212. A baffle 221 surrounds the edge of the feeding push plate 202, and a stop plate 222 is mounted on the edge of the feeding push plate 202 near the push-pull handle 213. The upper surface of the stop plate 222 is higher than the upper surface of the feeding push plate 202. The baffle 221 has through holes corresponding to the channel steel 212 and the feeding slide rail 201 for the channel steel 212 and the feeding slide rail 201 to pass through.

[0074] In this embodiment, the channel steel 212 is fixedly installed at the bottom of the feeding push plate 202, serving to support and connect the slider 211 and the feeding push plate 202. The push-pull handle 213 is installed on the channel steel 212, facilitating pushing or pulling back the feeding push plate 202.

[0075] A baffle 221 is provided at the edge of the feeding push plate 202 to ensure that the edge of the pearl cotton 4 is precisely aligned when it is fed into the slotted section 3, thereby ensuring the accuracy and efficiency of the operation. At the same time, the baffle 221 can also prevent the pearl cotton 4 from falling under the feeding push plate 202 after the slotting is completed, thereby ensuring the smooth operation of the feeding push plate 202. Through holes are provided at the positions of the baffle 221 corresponding to the channel steel 212 and the feeding slide rail 201, so that the slider 211, channel steel 212 and other structures can slide freely without being blocked by the baffle 221.

[0076] In this embodiment, the stop plate 222 is located on the edge near the push-pull handle 213. A spacer plate 223 is also provided on the feeding push plate 202 in front of the stop plate. The spacer plate 223 is made of cardboard. The stop plate 222 and the spacer plate 223 press against the rear edge of the pearl cotton 4 to ensure that the pearl cotton 4 is smoothly fed into the slotted part 3. When the pearl cotton 4 is completely fed into the slotted part 3, the presence of the spacer plate 223 can ensure the distance between the hand and the slotted part 3, reducing the safety hazards during use. Example

[0077] The similarities with the above embodiments and their combinations will not be repeated, the differences being:

[0078] See Figure 6 The support frames 311 on both sides of the threaded screw 312 are symmetrically provided with slide rods 316. The displacement frame 314 has a sliding hole corresponding to the slide rod 316. The displacement frame 314 is fixedly connected to the threaded sleeve 313 and slidably connected to the slide rod 316.

[0079] In this embodiment, two slide rods 316 are provided on both sides of the threaded screw 312 and cooperate with the slide holes on the displacement frame 314. This can effectively avoid the swaying, tilting or jamming caused by single-point transmission and ensure the stability and guiding accuracy of the entire adjustment process. Example

[0080] The similarities with the above embodiments and their combinations will not be repeated, the differences being:

[0081] See Figure 5 The tool holder 333 has a groove adapted to the shape of the blade 334. The blade 334 is disposed in the groove of the tool holder 333 and is fixedly installed by a fixing handwheel 335. The sliding member 331 is also provided with a positioning handle 336. The positioning handle 336 is connected to a cam. By rotating the positioning handle 336, the cam is rotated to press against the slide groove of the frame 302, thereby fixing the position of the sliding member 331.

[0082] In this embodiment, the tool holder 333 has a groove that matches the shape of the blade 334. The blade 334 is embedded in the groove and is manually tightened by the fixing handwheel 335. This structure not only ensures the stability and consistency of the blade installation but also supports quick replacement of blades of different shapes or angles to meet different grooving requirements. At the same time, rotating the positioning handle 336 drives the cam to move. After the cam rotates, it presses against the inner wall of the slide groove, thereby locking the position of the sliding member 331. The mechanical locking structure is simple and reliable, requiring no additional power drive.

[0083] In addition, a pointer 337 is also provided on the slider 331. In actual production, the pointer is used in conjunction with a scale or ruler engraved on the frame 302 to indicate the precise position of the current grooving unit, improving adjustment accuracy and ease of operation. This is suitable for occasions where multiple sets of tools need to be adjusted synchronously or where products of the same size need to be repeatedly processed. Example

[0084] The similarities with the above embodiments and their combinations will not be repeated, the differences being:

[0085] See Figure 1 , Figure 3 , Figure 6 The support frame 311 has an oblique slot, and a discharge guide plate 304 is inserted into the oblique slot. A discharge elastic guide plate 341 is provided on the side of the discharge guide plate 304. The discharge elastic guide plate 341 is made of PET sheet material. There is a gap between the discharge elastic guide plate 341 and the feeding part 2. The height of the gap is less than the thickness of the pearl cotton 4 to be grooved.

[0086] In this embodiment, the discharge smoothing plate 304 is fixed by inserting into an oblique slot, making installation simple. Its position is close to the discharge end after grooving, guiding, straightening, and flattening the grooved pearl cotton. This prevents the material from warping, shifting, or deforming due to its own elasticity or external vibration, thus affecting subsequent processing or the quality of the finished product.

[0087] Its material is PET (polyethylene terephthalate) sheet, which has good elasticity, wear resistance and anti-aging properties; the discharge elastic plate 341 is attached to one side of the discharge path and slightly presses the surface of the pearl cotton, which can stabilize the material running trajectory and reduce shaking and deviation without damaging the material.

[0088] A small gap, slightly smaller than the thickness of the pearl cotton 4, is left between the discharge elastic plate 341 and the feeding section 2. This design ensures that the pearl cotton 4 experiences moderate pressure as it passes through, further improving its conveying stability and positioning accuracy. It also avoids problems such as excessive friction, increased resistance, or even material jamming caused by an excessively small gap.

[0089] Meanwhile, since the gap between the discharge elastic plate 341 and the feeding push plate 202 is smaller than the thickness of the pearl cotton 4, when the pearl cotton 4 completely passes through the discharge elastic plate 341 under the action of the feeding push plate 202, the grooved pearl cotton 4 will be blocked by the discharge elastic plate 341 when the feeding push plate 202 is pulled back, and then fall off the feeding push plate 202. When the feeding push plate 202 returns to its initial position, the grooved pearl cotton 4 on it has been completely cleaned, thus ensuring the cleanliness of the feeding push plate 202 and its readiness for the next operation. The above structure not only improves work efficiency but also ensures the accuracy and continuity of operation.

[0090] In addition, it should be noted that in actual production, the discharge elastic plate 341 of this device can be fixed or detachably fixed to the side of the discharge plate 304 in various ways, including but not limited to screw fixing, bolt fixing, rivet fixing, bonding, snap-fit ​​and other structures. As long as the structure can fix or detachably fix the discharge elastic plate 341 to the discharge plate 304, it is within the protection scope of this embodiment. Example

[0091] The similarities with the above embodiments and their combinations will not be repeated, the differences being:

[0092] See Figure 2 , Figure 5 A feeding guide plate 305 is provided on the back side of the trellis 302 behind the sliding member 331. The feeding guide plate 305 is mounted on the back side of the trellis 302 by positioning bolts 351. A feeding elastic guide plate 352 is provided between the feeding guide plate 305 and the back side of the trellis 302. The feeding elastic guide plate 352 is also a thin PET sheet. The gap height between the feeding elastic guide plate 352 and the discharge elastic guide plate 341 and the feeding part 2 is the same. Both the feeding elastic guide plate 352 and the feeding guide plate 305 have oblong holes. The positioning bolts 351 are used to install the feeding elastic guide plate 352 and the feeding guide plate 305 on the back side of the trellis 302 through the oblong holes.

[0093] In this embodiment, the feeding guide plate 305 is disposed at the material input end of the grooving section 3 to pre-compress and level the pearl cotton that is about to enter the grooving area. This prevents the material from warping, shifting, or misaligning due to its own elasticity or external vibration, thereby affecting the subsequent grooving accuracy. The feeding guide plate 305 is fixedly installed on the back side of the truss by positioning bolts 351, which makes the structure stable and easy to disassemble and maintain.

[0094] The feed elastic plate 352 is also made of PET sheet, which has good elasticity, wear resistance and anti-aging properties. The feed elastic plate 352 is located at the front end of the feeding path. When the pearl cotton 4 is fed into the slotted part 3, it slightly presses the surface of the pearl cotton. Under the premise of ensuring that the material is not damaged, it plays a role in stabilizing the material running trajectory and reducing deviation.

[0095] Meanwhile, in this embodiment, the feed elastic plate 352 and the feed material plate 305 are installed on the back side of the truss 302 through the waist-shaped hole, allowing the feed elastic plate 352 and the feed material plate 305 to be adjusted up and down to accommodate pearl cotton materials of different thicknesses.

[0096] Furthermore, in this embodiment, the feeding guide plate 305 is an angled folded plate. The folded edge of the feeding guide plate 305 guides the feeding elastic guide plate 352, ensuring that its bottom has a certain angle after passing through the folded edge, facilitating the feeding of the pearl cotton 4. While adjusting the feeding elastic guide plate 352 up and down, the distance between the feeding elastic guide plate 352 and the blade 334 can be adjusted under the guiding action of the feeding guide plate 305, ensuring the accuracy and efficiency of the cutting process.

[0097] By adjusting the position of the positioning bolt 351 in the oblong hole, the gap height between the elastic guide plate and the feeding section can be precisely controlled. This gap design is consistent with the gap between the discharge elastic guide plate 341 and the feeding section, ensuring that the material is subjected to uniform force and runs smoothly throughout the entire conveying process.

[0098] The working principle of this pearl cotton grooving machine:

[0099] When using this utility model, the pearl cotton material to be processed is first placed on the feeding push plate 202, and its rear edge is pressed tightly against the partition plate 223 to ensure accurate material positioning. Then, the operator pushes the feeding push plate 202 by holding the push-pull handle 213, so that it slides forward along the feeding slide rail 201, and drives the pearl cotton material into the processing area below the slotted part 3.

[0100] During this process, the feeding elastic plate 352 and the discharging elastic plate 341 are located at the front and rear ends of the material, respectively, applying appropriate pressure to the surface of the pearl cotton 4. When the pearl cotton material is completely fed into the grooved section 3, the blade 334 of the grooving unit 303 cuts and grooves the pearl cotton 4. The grooving is completed when the pearl cotton 4 has completely passed through the grooving unit 303 and been pushed past the position of the discharging elastic plate 341.

[0101] After completing one grooving operation, the operator pulls the feeding push plate 202 back to the initial position. During this process, the grooved pearl cotton automatically falls off the feeding push plate 202 due to the blocking effect of the discharge elastic plate 341, ensuring that the feeding push plate 202 is in a clean state when it is reset, which is convenient for the next round of feeding operation.
