Description

Technical Field

[0001] The invention belongs to the technical field of foam board cutting, and specifically refers to a reciprocating foam board layer-by-layer cutting device. Background Art

[0002] The foam boards used for packaging are mostly large-area thin plates, which are mainly used to prevent damage to the internal products caused by impact during transportation by comprehensive protection or filling gaps. When the foam is first produced, it is mostly a whole piece and needs to be cut into thin plates of uniform thickness. The mechanical blade cutting method is not suitable for cutting this soft but low-hardness material due to the high pressure. The blade and saw blade will also produce a lot of debris during cutting, and secondary edge sealing is required after cutting.

[0003] Therefore, high temperature wire cutting is a more ideal cutting method, which uses the high heat of the steel wire to melt the foam around it for cutting.

[0004] The higher the temperature of the cutting wire, the larger the range that can be melted. Therefore, in order to ensure the smoothness of the cutting surface, the temperature fluctuation range of the cutting wire needs to be controlled; if the temperature is too low, it may not be able to melt the surrounding foam and then turn to mechanical cutting, and the mechanical cutting method is difficult to ensure the flatness of the cut surface; if the temperature is too high, it may cause the surrounding foam to melt excessively, and at this time the cut surface will have pits relative to other positions. Summary of the invention

[0051] like Figure 1 to Figure 11 As shown, the present invention proposes a reciprocating foam board layer-by-layer cutting device, including a material clamping and translational mechanism 1, an adaptive temperature control mechanism 2, a material movement mechanism 3 and an electric heating wire cutting mechanism 4, the material movement mechanism 3 is arranged on the material clamping and translational mechanism 1, the electric heating wire cutting mechanism 4 is arranged on the material clamping and translational mechanism 1, and the adaptive temperature control mechanism 2 is arranged on the electric heating wire cutting mechanism 4.

[0053] Through the limiting and guiding of the material clamping and translating mechanism 1, the material can be automatically advanced step by step during the reciprocating sliding process, thereby achieving a cutting effect of a specific thickness.

[0054] The guide groove assembly 6 includes a fixed guide plate 11, a first detachable guide plate 12 and a second detachable guide plate 13. The fixed guide plate 11 is arranged on the cutting table 5. An array of fine slide grooves 19 is arranged on the fixed guide plate 11.

An array of transverse slide grooves 20 is arranged on the first detachable guide plate 12. The transverse slide grooves 20 are connected through an oblique slide groove 21. The second detachable guide plate 13 is provided with transverse slide grooves 22 in an array. The transverse slide grooves 22 are connected through an oblique slide groove 23.

[0055] The sliding guide assembly 7 includes a square frame clamp 14 and a special-shaped slider 15. The special-shaped slider 15 is clamped at the bottom of the square frame clamp 14. The special-shaped slider 15 is symmetrically arranged on the square frame clamp 14.

The cantilever slide rod portion 25 can slide in the horizontal slide groove 1 20 and the oblique slide groove 1 21, and the cantilever slide rod portion 25 can slide in the horizontal slide groove 2 22 and the oblique slide groove 2 23.

[0056] The slide bar portion 24 can slide in the thin slide groove 19, and the cantilever slide bar portion 25 can push the material to move horizontally as a whole under the guidance of the oblique slide groove 1 21 or the oblique slide groove 23; the cantilever slide bar portion 25 first enters the transverse slide groove 1 20 or the oblique slide groove 23, and the slide bar portion 24 will be separated from the thin slide groove 19, so that the movement of the frame clamp 14 is smooth, stable and controllable; when the cantilever slide bar portion 25 slides in the oblique slide groove 1 21 or the oblique slide groove 23, the slide bar portion 24 has been separated from the thin slide groove 19, so as to avoid jamming; when the cantilever slide bar portion 25 is separated from the transverse slide groove 1 20 or the transverse slide groove 22, the slide bar portion 24 has been combined with the thin slide groove 19 again, and cutting of a specific thickness can be achieved through a cyclic advance method.

[0057] The clamping assembly 8 includes a fixed clamp 16, a movable clamp 17 and a clamping spring 18. The fixed clamp 16 is fixedly connected to the inner wall of the square clamp 14. The movable clamp 17 is provided with a guide rod 26. The movable clamp 17 is slidably engaged with the square clamp 14 through the guide rod 26. The clamping spring 18 is arranged between the square clamp 14 and the movable clamp 17.

[0058] The object gradually slides toward the direction where the movable clamping plate 17 is located, so that the cutting coordinates can always remain accurate when based on the special-shaped slider 15, avoiding the coordinate changes caused by the change of the total thickness of the material when hot melt cutting will lose part of the material.

[0059] The electric heating wire cutting mechanism 4 includes a cantilever support assembly 43 and a cutting wire driving assembly 44 . The cantilever support assembly 43 is arranged on the side of the cutting table 5 , and the cutting wire driving assembly 44 is arranged on the cantilever support assembly 43 .

[0060] The cantilever support assembly 43 includes a support mounting seat 45 , a cantilever support 46 and an idler wheel 47 . The support mounting seat 45 is disposed on the cutting table 5 , the cantilever support 46 is disposed on the support mounting seat 45 , and the idler wheel 47 is rotatably disposed on the cantilever support 46 .

[0061] The cutting wire drive assembly 44 includes a driving wheel 48 and a clamping wheel 49 , and the metal cutting wire 32 is located between the driving wheel 48 and the clamping wheel 49 .

[0062] Through the clamping of the clamping wheel 49 and the driving wheel 48, a stable rolling contact relationship can be maintained between the cutting wire driving assembly 44 and the metal cutting wire 32 to avoid slipping. Through the active rotation of the driving wheel 48, the metal cutting wire 32 can be driven to circulate.

[0063] The adaptive temperature control mechanism 2 includes a power supply component 27 and a temperature sensing component 28 . The power supply component 27 is disposed on the cantilever support component 43 , and the temperature sensing component 28 is disposed on the cantilever support component 43 .

[0064] The power supply assembly 27 includes a power supply 29, a power supply wire 30, a conductive roller 31 and a metal cutting wire 32. The power supply 29 is arranged on a cantilever bracket 46, the conductive roller 31 is rotatably arranged on the cantilever bracket 46, and the metal cutting wire 32 is rollingly arranged on the conductive roller 31 and the idler wheel 47.

[0065] Through the power supply of the power supply 29 and the connection of the conductive roller 31, the metal cutting wire 32 can be divided into two loops, wherein the loop used for cutting is shorter, has a smaller resistance, and has a larger current, so the temperature is relatively high, while the loop used for heat preservation is longer, has a larger resistance, and has a smaller current, so the temperature is relatively low; this scheme can make the temperature of the cutting part high enough (to ensure the cutting effect) and the temperature of the non-cutting part moderate (too high will cause excessive melting, and too low will cause the heating time to be too long during cutting, affecting the cutting effect) by reasonably allocating energy.

[0066] The temperature sensing assembly 28 includes a resistor bracket 33 and a thermistor 34. The resistor bracket 33 is arranged on the cantilever bracket 46, and the thermistor 34 is arranged on the resistor bracket 33. The metal cutting wire 32 is located in the central through hole of the thermistor 34. The conductive roller 31, the power supply 29 and the thermistor 34 are electrically connected through the power supply wire 30. The resistance value of the thermistor 34 increases with the increase of temperature.

[0067] The resistance of the thermistor 34 can change with the temperature of the metal cutting wire 32 at the cutting part, and affect the heating power through its own resistance change, thereby achieving the technical purpose of automatically compensating the temperature and maintaining it in a relatively constant range.

[0068] The material moving mechanism 3 includes a spring assembly 35 and a sliding drive assembly 36 . The spring assembly 35 is arranged between the cutting table 5 and the sliding guide assembly 7 . The sliding drive assembly 36 is arranged on the side of the cutting table 5 . The sliding drive assembly 36 is connected to the sliding guide assembly 7 .

[0069] The spring assembly 35 includes a spring mounting seat 37 , an advance spring 38 and a downward pressure spring 39 . The spring mounting seat 37 is arranged on the cutting table 5 , the advance spring 38 is arranged between the spring mounting seat 37 and the square frame clamp 14 , and the downward pressure spring 39 is arranged between the square frame clamp 14 and the cutting table 5 .

[0070] The feed direction of the material can be controlled by the advance spring 38 to achieve the technical purpose of cutting layer by layer; the downward pressure spring 39 can press the square clamp 14 toward the cutting table 5 together with the advance spring 38, so that the special-shaped slider 15 can run under the guidance of the guide groove assembly 6, avoiding the sliding guide assembly 7 from slipping upward.

[0071] The sliding drive assembly 36 includes a driving motor 40, a cantilevered driving rod 41 and a sliding rocker 42. The driving motor 40 is arranged on the cutting table 5. The cantilevered driving rod 41 is clamped on the output shaft of the driving motor 40. One end of the sliding rocker 42 is hinged to the frame clamp 14, and the other end of the sliding rocker 42 is hinged to the end of the cantilevered driving rod 41.

[0072] like Fig.12 As shown, R1 represents the short metal cutting wire 32 between the two conductive rollers 31, which is used for cutting, and R2 represents the long metal cutting wire 32 between the two conductive rollers 31, which is not used for cutting; R3 represents the thermistor 34, the circuit length for cutting is short, the resistance value is small, the current is large, so the temperature is relatively high, while the circuit length for heat preservation is long, the resistance value is large, the current is small, so the temperature is relatively low; this scheme can make the temperature of the cutting part high enough (to ensure the cutting effect) and the temperature of the non-cutting part moderate (too high will cause excessive melting, too low will cause too long heating time when used for cutting, affecting the cutting effect) by reasonably allocating energy;

[0073] When R3 increases, the current in both branches decreases.

[0074] When in use, the user first starts the driving wheel 48, and the cutting wire driving assembly 44 causes the metal cutting wire 32 to continuously rotate; and the material is clamped between the fixed clamping plate 16 and the movable clamping plate 17, and the material can be clamped by the elastic force of the clamping spring 18; then the driving motor 40 is started, and the square frame clamp 14 is reciprocated and slid by the movement of the sliding driving assembly 36;

[0075] When the special-shaped slider 15 slides to the end where the first detachable guide plate 12 is located, before the slide bar portion 24 disengages from the fine slide groove 19, the cantilever slide bar portion 25 will first enter the horizontal slide groove 20, and when the special-shaped slider 15 slides to reset in the opposite direction, the cantilever slide bar portion 25 will enter the adjacent horizontal slide groove 20 through the oblique slide groove 21, and the square frame clamp 14 is continuously subjected to the pulling force from the advance spring 38 during the reciprocating sliding process. Therefore, during the process of the square frame clamp 14 sliding toward the direction where the cutting wire drive assembly 44 is located, the slide bar portion 24 and the fine slide groove 19 are not in contact. During the reverse sliding, before the cantilever slide bar portion 25 disengages from the horizontal slide groove 20, the slide bar portion 24 has been combined with the fine slide groove 19 again;

[0076] When the special-shaped slider 15 slides to the end where the second detachable guide plate 13 is located, its movement mode is the same as the above process;

[0077] On the first detachable guide plate 12 and the second detachable guide plate 13 of different specifications, the spacing between the transverse slide groove 1 20 and the transverse slide groove 2 22 is different. By replacing the first detachable guide plate 12 and the second detachable guide plate 13 of different specifications, the cutting thickness can be adjusted, and the spacing between the transverse slide groove 1 20 and the transverse slide groove 2 22 should be an integer multiple of the spacing between the fine slide groove 19.

[0078] During the movement of the material, the metal cutting wire 32 can be heated by the power supply 29. By the power supply of the power supply 29 and the connection of the conductive roller 31, the metal cutting wire 32 can be divided into two loops, wherein the loop for cutting is shorter, has a smaller resistance value, and has a larger current, so the temperature is relatively higher, while the loop for heat preservation is longer, has a larger resistance value, and has a smaller current, so the temperature is relatively lower. This solution can make the temperature of the cutting part high enough (to ensure the cutting effect) and the temperature of the non-cutting part moderate (too high will cause excessive melting, and too low will cause the heating time to be too long during cutting, affecting the cutting effect) by reasonably allocating energy.

[0079] If the temperature of the metal cutting wire 32 used for cutting deviates, it will cause the resistance value of the thermistor 34 to change; when the temperature of the metal cutting wire 32 used for cutting is high, the resistance value of the thermistor 34 increases, at this time the total resistance value in the circuit increases, the current passing through the metal cutting wire 32 decreases, thereby reducing the heating power, so that the temperature of the metal cutting wire 32 used for cutting is restored; when the temperature of the metal cutting wire 32 used for cutting is low, the resistance value of the thermistor 34 decreases, at this time the total resistance value in the circuit decreases, the current passing through the metal cutting wire 32 increases, thereby increasing the heating power, so that the temperature of the metal cutting wire 32 used for cutting is restored.

[0080] During the material cutting process, a certain thickness of the material will be lost, so the movable clamping plate 17 is actually in continuous motion. Therefore, the movement toward the movable clamping plate 17 and based on the fixed clamping plate 16 can avoid the error caused by the total thickness loss.

[0081] After the cutting is completed, the material is removed, and then the square frame clamp 14 is lifted up manually to overcome the elastic force of the spring mounting seat 37 and the downward pressure spring 39, and then the square frame clamp 14 can be reset.

[0082] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
