Description

Technical Field

[0001] The present invention relates to the technical field of embossing die equipment, in particular to a thermoforming die with embossing function and a use method thereof. Background Art

[0002] After the production of the electric blanket is completed, the outside of the electric blanket needs to be embossed. Embossing of electric blankets is a common process in electric blanket production. Specific textures or patterns are formed on the surface or internal structural layer of the blanket through physical stamping, which has both functional value and aesthetic needs.

[0003] However, the existing electric blanket embossing mold is not convenient for simultaneously flattening the electric blanket to be embossed while embossing the electric blanket, which may cause wrinkles to appear on the embossed electric blanket, thereby affecting the efficiency and accuracy of the embossing mold in embossing the electric blanket. Therefore, a thermoforming mold with embossing function and a method of using it are needed to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide a thermoforming die with embossing function and a method of using the same, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a thermoforming mold with an embossing function, comprising a positioning base for support, a material guide chute is provided at the middle of the upper end surface of the positioning base, and two groups of support guide shafts are symmetrically arranged on the upper end surface of the positioning base, and a support clamp is fixedly provided on the top of the two groups of support guide shafts.

[0007] An embossing device, the embossing device is fixedly arranged at the output end of the thin cylinder, and slot-type photoelectric switches are arranged on both sides of the embossing device, and the embossing device is used for embossing and shaping;

[0008] The guide device is provided with two groups, and both groups of the guide devices are slidably arranged on the side of the embossing device, and the guide device is used to flatten the side of the embossed electric blanket.

[0009] Preferably, the embossing device includes a mold slide, two groups of guide slides are symmetrically arranged on the side end surface of the mold slide, and positioning guide grooves are opened at the four corners of the inner end surface of the mold slide, an imprinting mold is arranged at the center of the lower end surface of the mold slide, and a heating module is arranged on the upper end surface of the imprinting mold.

[0010] Preferably, the guide device includes a supporting device for supporting, the inner end surface of the supporting device is rotatably connected with two groups of limiting guide rollers, and driven bevel gears are provided at the middle of the inner end surfaces of the two groups of limiting guide rollers, and two groups of synchronous pulleys are rotatably connected at the upper part of the inner end surface of the supporting device, and the two groups of synchronous pulleys are meshed with each other through synchronous belts, and a stepper motor is provided at the upper end surface of the supporting device facing the synchronous pulley at the rear, and an active bevel gear is provided at the center of the lower end surface of the two groups of synchronous pulleys.

[0011] Preferably, the supporting device includes a pressing base for support, a positioning guide seat is provided at the center of the upper end surface of the pressing base, and a baffle is provided at the rear part of the upper end surface of the positioning guide seat, guide slide shafts are symmetrically provided on both sides of the upper end surface of the pressing base, and a support spring is provided at the upper end surface of the pressing base opposite to the guide slide shaft.

[0012] Preferably, the mold slide is adapted to the support guide shaft through the positioning guide groove and then slidably engaged with the upper end surface of the positioning base, which can effectively improve the stability of the subsequent mold slide's up and down displacement embossing pattern on the upper part of the positioning base.

[0013] Preferably, the embossing mold and the pressing base are both slidably connected to the inner end surface of the material guide chute, which can effectively improve the accuracy of the embossing mold on the electric blanket inside the material guide chute. At the same time, the sliding limit of the pressing base and the material guide chute can also improve the efficiency of the limiting guide roller in leveling the electric blanket inside the material guide chute.

[0014] Preferably, the driven bevel gear is meshed with the active bevel gear, and the pressing base is adapted to the guide slide through the guide slide shaft and then elastically slidably engaged with the lower end surface of the mold slide. The sliding limit of the two sets of guide slide shafts and the guide slide can effectively improve the stability of the pressing base displacement under the mold slide. At the same time, the support spring is fixedly connected to the bottom of the mold slide, which can provide sufficient elastic force for the limiting guide roller for leveling.

[0015] Preferably, when the baffle is displaced to the top, it coincides with the middle of the slot-type photoelectric switch, and the two sets of synchronous pulleys are rotated and clamped on the inner end surface of the alignment guide seat. Before the electric blanket is leveled, the two sets of limiting guide rollers are driven by the mold slide to continuously press down. When the baffle coincides with the slot-type photoelectric switch, the pressure just reaches the preset value, so that the stepper motor can reversely roll the electric blanket through the two sets of limiting guide rollers, so that the middle part of the electric blanket is leveled, thereby improving the stability of the embossed pattern.

[0016] A method for using a thermoforming mold with an embossing function comprises the following steps:

[0018] S2: Embossing and leveling: The thin cylinder can drive the mold slide and two sets of guide devices to move downward synchronously. The two sets of limit guide rollers can press and limit the electric blanket. At the same time, the mold slide and the pressing base continue to move downward. The support spring is in an elastic contraction state. The baffle can be lifted into the inside of the slotted photoelectric switch. The stepper motor is started. The stepper motor can synchronously drive the two sets of active bevel gears at the bottom to rotate through the synchronous pulley and synchronous belt. The active bevel gear can mesh with the driven bevel gear, thereby driving the front and rear sets of limit guide rollers to rotate. The front and rear sets of limit guide rollers can rotate synchronously in opposite directions, thereby performing a full range of leveling operations on the elastically pressed electric blanket.

[0019] S3: Embossing reset. After leveling is completed, the thin cylinder can drive the mold slide to continue to move downward, so that the mold slide can drive the stamping mold to emboss the outside of the electric blanket. Then the thin cylinder drives the mold slide to reset, and the mold slide drives the guide device to reset.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets a guide device. When embossing the electric blanket, the thin cylinder can synchronously drive the mold slide and the pressing base to move downward. The pressing base can pre-elastically press the electric blanket through the limiting guide roller. Then, after the slot-type photoelectric switch senses the baffle, it can synchronously drive the front and rear two groups of limiting guide rollers to rotate synchronously in opposite directions through two groups of stepper motors, so that the front and rear two groups of stepper motors can synchronously move the electric blanket outward, so that the middle part of the electric blanket to be embossed is flattened and straightened, effectively improving the efficiency and stability of the flattening of the electric blanket, and also improving the accuracy and stability of the subsequent embossing mold on the upper part of the electric blanket.

[0022] 2. The present invention provides a supporting device. When the electric blanket is embossed, the two sets of supporting springs can be continuously compressed when the mold slide moves downward, so that the two sets of limiting guide rollers have sufficient elastic pressure to limit the upper part of the electric blanket, thereby improving the stability of the subsequent two sets of limiting guide rollers in leveling the electric blanket. At the same time, the supporting springs can also provide elastic protection for the electric blanket to prevent damage to the electric blanket due to excessive pressure, thereby improving the protective performance of the equipment for electric blanket processing.

[0041] The embossing device 2 includes a mold slide 21, two groups of guide slides 22 are symmetrically arranged on the side end surface of the mold slide 21, and positioning guide grooves 25 are opened at the four corners of the inner end surface of the mold slide 21. An imprinting mold 23 is arranged at the center of the lower end surface of the mold slide 21, and a heating module 24 is arranged on the upper end surface of the imprinting mold 23.

A driven bevel gear 35 is provided at the middle part of the inner end surface of the two groups of limiting guide rollers 31, and two groups of synchronous pulleys 33 are rotatably connected to the upper part of the inner end surface of the support device 32. The two groups of synchronous pulleys 33 are meshed and connected by a synchronous belt 37. A stepping motor 34 is provided at the upper end surface of the support device 32 opposite to the rear synchronous pulley 33, and a driving bevel gear 36 is provided at the center of the lower end surface of the two groups of synchronous pulleys 33.

[0043] The supporting device 32 includes a pressing base 322 for support, a positioning guide seat 321 is provided at the center of the upper end surface of the pressing base 322, and a blocking piece 325 is provided at the rear part of the upper end surface of the positioning guide seat 321, guide slide shafts 324 are symmetrically provided on both sides of the upper end surface of the pressing base 322, and a support spring 323 is provided at the upper end surface of the pressing base 322 opposite to the guide slide shaft 324.

[0044] The mold slide 21 is adapted to the support guide shaft 5 through the positioning guide groove 25 and then slidably engaged with the upper end surface of the positioning base 4, which can effectively improve the stability of the subsequent mold slide 21 moving up and down on the upper part of the positioning base 4 to emboss the pattern.

[0045] The embossing mold 23 and the pressing base 322 are both slidably connected to the inner end surface of the material guide chute 6, which can effectively improve the accuracy of the embossing of the electric blanket inside the material guide chute 6 by the embossing mold 23. At the same time, the sliding limit of the pressing base 322 and the material guide chute 6 can also improve the efficiency of the limiting guide roller 31 in leveling the electric blanket inside the material guide chute 6.

[0046] The driven bevel gear 35 is meshed with the active bevel gear 36, and the pressing base 322 is adapted to the guide slide 22 through the guide slide shaft 324 and then elastically slides and is clamped on the lower end surface of the mold slide 21. The sliding limit of the two sets of guide slide shafts 324 and the guide slide 22 can effectively improve the stability of the pressing base 322 in the displacement of the lower part of the mold slide 21. At the same time, the support spring 323 is fixedly connected to the bottom of the mold slide 21, which can provide sufficient elastic force for the subsequent limiting guide roller 31 for leveling.

[0047] When the baffle 325 moves to the top, it coincides with the middle of the slot-type photoelectric switch 7. Both sets of synchronous pulleys 33 rotate and engage with the inner end surface of the alignment guide seat 321. Before leveling the electric blanket, the two sets of limiting guide rollers 31 continue to press down under the drive of the mold slide 21. When the baffle 325 coincides with the slot-type photoelectric switch 7, the pressure just reaches the preset value, so that the stepper motor 34 can reversely roll the electric blanket through the two sets of limiting guide rollers 31, so that the middle part of the electric blanket is leveled, thereby improving the stability of the embossed pattern.

[0048] A method for using a thermoforming mold with an embossing function comprises the following steps:

[0049] S1: Pre-installation: The staff can position the electric blanket feeding module to the front of the positioning base 4, and then position the electric blanket unloading module to the rear of the positioning base 4, thereby continuously supplying raw materials to the inside of the material guide chute 6;

[0050] S2: Embossing and leveling, the thin cylinder 8 can drive the mold slide 21 and the two sets of guide devices 3 to move downward synchronously, and the two sets of limiting guide rollers 31 can press and limit the electric blanket. At the same time, the mold slide 21 and the pressing base 322 continue to move downward, the support spring 323 is in an elastic contraction state, and the baffle 325 can be lifted to the inside of the slot-type photoelectric switch 7, and the stepper motor 34 is started. The stepper motor 34 can synchronously drive the two sets of active bevel gears 36 at the bottom to rotate through the synchronous pulley 33 and the synchronous belt 37. The active bevel gear 36 can mesh with the driven bevel gear 35, thereby driving the front and rear two sets of limiting guide rollers 31 to rotate. The front and rear two sets of limiting guide rollers 31 can rotate synchronously in opposite directions, thereby performing a full-scale leveling operation on the elastically pressed electric blanket;

[0051] S3: Embossing reset. After leveling is completed, the thin cylinder 8 can drive the mold slide 21 to continue to move downward, so that the mold slide 21 can drive the stamping mold 23 to emboss the outside of the electric blanket. Then the thin cylinder 8 drives the mold slide 21 to reset, and the mold slide 21 drives the guide device 3 to reset.

[0052] Working principle: Before use, the staff can position the electric blanket feeding module to the front of the positioning base 4, and then position the electric blanket unloading module to the rear of the positioning base 4, which can facilitate the subsequent continuous supply of raw materials to the inside of the material guide chute 6. When embossing the upper part of the electric blanket, the staff can start the thin cylinder 8. At this time, the thin cylinder 8 can drive the mold slide 21 to move downward. When the mold slide 21 moves downward, the mold slide 21 can synchronously drive the two sets of guide devices 3 to move downward synchronously. The two sets of guide devices 3 can fit the electric blanket before the mold slide 21. When the front and rear two sets of limiting guide rollers 31 move down to the upper part of the electric blanket, the two sets of limiting guide rollers 31 can press and limit the electric blanket. At the same time, as the mold slide 21 and the pressing base 322 continue to move downward, the support spring 323 is in an elastic contraction state, and the baffle 32 5 can be lifted to the inside of the slot-type photoelectric switch 7. At this time, the slot-type photoelectric switch 7 can synchronously start the two sets of stepper motors 34 to rotate in the opposite direction. At this time, the stepper motors 34 can synchronously drive the two sets of active bevel gears 36 at the bottom to rotate through the synchronous pulley 33 and the synchronous belt 37. At the same time, the active bevel gear 36 can mesh with the driven bevel gear 35, thereby driving the front and rear two sets of limiting guide rollers 31 to rotate. The front and rear two sets of stepper motors 34 rotate in opposite directions, so that the front and rear two sets of limiting guide rollers 31 can rotate synchronously in opposite directions, thereby performing a full-scale leveling operation on the elastically pressed electric blanket to prevent wrinkles in the electric blanket during embossing. After the leveling is completed, the mold slide 21 can drive the stamping mold 23 to emboss the outer surface of the electric blanket. Then the thin cylinder 8 drives the mold slide 21 to reset, and the mold slide 21 drives the guide device 3 to reset.
