[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figures 1 to 4 As shown, it is a first embodiment of a thick foam die-cutting processing device 100 of the utility model, which includes a processing table 10, a loading and unloading assembly 20, a fixing assembly 30, a flattening assembly 40 and a cutting mold 50.

[0024] The processing table 10 is provided with a mounting frame 11 and a punching cylinder 12, the mounting frame 11 stands in the middle of the upper end of the processing table 10, and the punching cylinder 12 is installed on the mounting frame 11. The loading and unloading assembly 20, the fixing assembly 30 and the flattening assembly 40 are all installed on the processing table 10, wherein the loading and unloading assembly 20 is located on both sides of the upper end of the processing table 10, the fixing assembly 30 is located below the mounting frame 11, the flattening assembly 40 is located between the loading and unloading assembly 20 and the fixing assembly 30, and the cutting die 50 is installed at the bottom end of the punching cylinder 12 and above the fixing assembly 30. The loading and unloading assembly 20 includes two groups of hoisting rollers 21, and the two groups of hoisting rollers 21 are installed on both sides of the upper end of the processing table 10 in a left-right symmetrical manner. The automatic unwinding and rewinding hoisting rollers 21 are provided for automatic loading and unloading, which is not only safe and reliable, but also more efficient in loading and unloading.

[0025] The fixing assembly 30 includes a lower fixing seat 31, an upper fixing plate 32 and a plurality of lifting gas rods 33. The lower fixing seat 31 is mounted on the processing table 10, and the upper fixing plate 32 is arranged above the lower fixing seat 31. The upper fixing plate 32 is provided with an outer frame knife hole 321 and a plurality of auxiliary knife holes 322, wherein the outer frame knife hole 321 corresponds to the outer frame knife 52 up and down, and the plurality of auxiliary knife holes 322 correspond to the plurality of auxiliary cutting knives 53 up and down, respectively. The plurality of lifting gas rods 33 are all mounted on the processing table 10 and their upper ends are all connected to the bottom of the upper fixing plate 32, and the plurality of lifting gas rods 33 can drive the upper fixing plate 32 to move up and down. Specifically, in the present embodiment, the bottom of the upper fixing plate 32 is also provided with a plurality of interlaced and connected grooves (not shown).

[0026] When the foam needs to be fixed, the upper fixing plate 32 can be driven down by the lifting gas rod 33 until it clamps and fixes the foam with the lower fixing seat 31. Then, during punching, the outer frame knife 52 and the auxiliary knife 53 can pass through the outer frame knife hole 321 and the auxiliary knife hole 322 to cut the foam. When the cutting is completed, the lifting gas rod 33 can drive the upper fixing plate 32 to rise again, thereby releasing the clamping fixation of the foam. The groove at the bottom of the upper fixing plate 32 can reduce the occurrence of problems such as the foam sticking back to the upper fixing plate 32 and affecting the demoulding and unloading.

[0027] The flattening assembly 40 includes two groups of transmission flattening rollers 41 that are symmetrical on both sides. The transmission flattening rollers 41 include a roller frame 411, a lower flattening roller 412, and an upper flattening roller 413. The roller frame 411 is mounted on the processing table 10 and is located between the loading and unloading assembly 20 and the fixing assembly 30. The lower flattening roller 412 and the upper flattening roller 413 are both mounted on the roller frame 411 in a clamping manner, and the two are arranged in an upper and lower direction. The flattening assembly 40 can smooth the foam passing through it through the flattening rollers, thereby avoiding the problem of poor die-cutting quality or even scrapping due to curling and wrinkling of the foam material.

[0028] The roller frame 411 includes a frame body 411a, an adjustment block 411b and an adjustment screw 411c. The frame body 411a is provided with a lifting slide hole 411d, the adjustment block 411b is mounted in the lifting slide hole 411d and can be moved up and down, the adjustment screw 411c is passed through the lifting slide hole 411d from top to bottom, and its lower end is movably connected to the adjustment block 411b. The flattening component 40 with adjustable roller spacing can pass through foam materials of different thicknesses, so that the processing device is suitable for foam die-cutting processing of more specifications.

[0029] The cutting mold 50 includes a template 51, an outer frame knife 52 and a plurality of auxiliary cutters 53. The outer frame knife 52 is designed with an annular blade structure and is installed at the bottom of the template 51. The plurality of auxiliary cutters 53 are designed with a sheet blade structure, which is installed at the bottom of the template 51 and distributed around the outer frame knife 52. The bottom height of the plurality of auxiliary cutters 53 is also greater than the bottom height of the outer frame knife 52.

[0030] When cutting the foam, the template 51 and the outer frame knife 52 and the auxiliary cutter 53 installed at the bottom of the template 51 are pressed downwards under the drive of the punching cylinder 12. First, the blade of the outer frame knife 52 contacts the upper surface of the foam. When the outer frame knife 52 cuts into a quarter of the thickness of the foam, the blade of the auxiliary cutter 53 also begins to contact the upper surface of the foam, and then the two blades synchronously cut the foam downwards. Due to the auxiliary positioning of the peripheral auxiliary cutter 53, the outer frame knife 52 can greatly reduce the risk of beveling or denting when cutting the foam.

[0031] like Figures 5 to 7 As shown, it is a second embodiment of a thick foam die-cutting processing device 100 of the utility model, which is basically the same as the first embodiment, and the difference is that:

[0032] The template 51 includes a lower template 511, an upper template 512 and a plurality of adjustment bolts 513. The lower template 511 is provided with a plurality of long holes 511a, and the outer frame knife 52 is installed at the bottom of the lower template 511. The upper template 512 is arranged above the lower template 511. The upper template 512 is also provided with a plurality of adjustment screw holes 512a that penetrate upward and downward. A plurality of auxiliary cutters 53 are all installed at the bottom of the upper template 512 and penetrate the long holes 511a from top to bottom. A plurality of adjustment bolts 513 are all penetrated through the adjustment screw holes 512a from top to bottom, and their bottom ends are movably connected to the lower template 511.

[0033] The upper and lower templates 511 with movable adjustable spacing can simultaneously adjust the height difference between the outer frame knife 52 and the auxiliary cutter 53, so that when the cutting mold 50 punches foams of different thicknesses, the height difference between the outer frame knife 52 and the auxiliary cutter 53 is always kept at one-fourth of the foam thickness to achieve the best die-cutting effect.

[0034] The thick foam die-cutting processing device 100 further includes an intelligent control system (not shown), and a plurality of detectors 34 are further provided at the upper end of the upper fixing plate 32. The detectors 34 include an elastic telescopic rod 341 and a pressure detection sensor 342, wherein the elastic telescopic rod 341 is installed at the upper end of the upper fixing plate 32, and the pressure detection sensor 342 is installed at the top of the elastic telescopic rod 341 and is connected to the intelligent control system signal.

[0035] When the template 51 is driven downward by the punching cylinder 12, its bottom will abut against the pressure detection sensor 342, and the dispersed multiple groups of pressure detection sensors 342 will send a signal to the intelligent control system when receiving the pressure of the knife abutting. If the time when each pressure detection sensor 342 sends a signal is inconsistent, it means that the punching stroke of the cutting mold 50 is skewed, and the intelligent control system will automatically control the processing device to stop running and readjust the horizontal state of the device, ultimately ensuring that the cutting process of the foam is more straight and neat.

[0036] In summary, the beneficial effects of the thick foam die-cutting processing device 100 of the utility model are: by additionally providing an auxiliary cutter 53 outside the outer frame knife 52 of the cutting mold 50, the auxiliary cutter 53 is used to position the foam when the blade of the outer frame knife 52 cuts into the foam, which can effectively avoid problems such as slanting or sinking of the foam; the cutting mold 50 is designed with an adjustable blade height difference, so that it can be suitable for die-cutting of foams of different thicknesses; the fixing component 30 can effectively fix the foam to avoid the problem of sliding and offsetting of the foam during the punching process; and the flattening component 40 can flatten the fixed foam to avoid affecting the die-cutting quality due to foam wrinkles; the utility model is highly practical and has a strong promotional significance.

[0037] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
