Description

Technical Field

[0001] The invention belongs to the technical field of baking production of EVA thin plates, and in particular relates to automatic feeding type baking production equipment and a production process of EVA thin plates. Background Art

[0002] The car's front panel refers to the partition between the engine compartment and the car body, which plays a role in heat insulation and sound insulation. The materials used for the car's front panel are usually EVA sheets and other materials.

[0003] Baking production is an important link in the process of using EVA sheets in the front of the car. It is of great significance to improve product quality, ensure product performance and meet production needs. At present, when baking EVA sheets, the EVA sheets are not preheated and re-baked in sequence, so that the temperature of the EVA sheets will rise or fall sharply during baking, making the EVA sheets easy to crack, and the quality of the EVA sheets baking is not well guaranteed;

[0004] When baking EVA sheets, multiple EVA sheets cannot be baked continuously, and the machine needs to be stopped when loading or unloading. In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and to provide an automatic loading type EVA thin sheet baking production equipment and a production process which can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: automatic loading type EVA thin sheet baking production equipment and production process, including a conveying mechanism; a conveying mechanism to realize automatic conveying of EVA thin sheets; an automation mechanism, the automation mechanism automatically collects the EVA thin sheets; a baking mechanism, the conveying mechanism conveys the EVA thin sheets into the baking mechanism for baking; a baking limiting mechanism, the conveying mechanism conveys the EVA thin sheets into the baking mechanism for preheating, baking and heat dissipation through the baking limiting mechanism.

[0007] Furthermore, the conveying mechanism includes: a conveying main motor, which provides power for the conveying mechanism; a transmission screw, which is divided into two groups and is arranged on the conveying main motor and is powered by the conveying main motor to work; a stabilizing slider, the inner circle of the stabilizing slider is provided with internal teeth that are meshed and connected with the transmission screw; and an auxiliary slide rod, which is provided with two groups on the stabilizing slider and is slidably connected to the stabilizing slider to provide stability for the stabilizing slider.

[0008] Furthermore, the automation mechanism includes: a small motor, which provides power output for the automation mechanism; a stretching slide rod, which is provided with two groups at both ends of the small motor and is symmetrically and evenly distributed; a stretching cross tooth block, which is provided on the end of the stretching slide rod away from the small motor; a rolling gear, which is meshed and connected to the top of the stretching cross tooth block; a fixed rod, which passes through the rolling gear and is fixedly connected to another group of rolling gears; a thin plate tray, which is made of stainless steel and high temperature resistant material and is fixedly connected to the top of the fixed rod; a thin plate groove, which is provided on the surface of the thin plate tray; a baking limit electromagnet, which is provided by the small motor to obtain magnetism and has a maximum high temperature resistance of ℃.

[0009] Furthermore, the baking mechanism includes: a baking motor, which provides power output for the baking mechanism; a heat preservation tank, which is arranged below the baking motor to insulate the heat source; a heating pipe, which is arranged inside the heat preservation tank and provides a heat source for the heat preservation tank under the power output of the baking motor; a heat preservation iron sheet, which is made of iron and surrounds the baking mechanism; a hot air tank, which is provided with openings of the same size and provides a heat source for the interior of the baking mechanism; an air inlet, which provides external cold air to enter the baking mechanism; an air intake hot air duct, which provides the heat source inside the heat preservation tank to the hot air tank; an air outlet, which dissipates the hot air inside the baking mechanism to the outside; a baking limiting tank, which is provided with three groups at the inner bottom of the baking mechanism; and high-temperature resistant heat preservation asbestos, which is provided between the hot air tank and the heat preservation iron sheet.

[0010] Furthermore, the baking limiting mechanism includes: a three-way slide groove, which is arranged inside the baking limiting mechanism; a three-way slider, which is slidably connected on the three-way slide groove; and two groups of limiting magnetic blocks are arranged inside the three-way slide groove.

[0011] Furthermore, two groups of baking limiting mechanisms are arranged inside the baking mechanism, and the magnetic temperature of the limiting magnetic block at the end closest to the conveying main motor is set at a maximum of 40°C, and the magnetic temperature of the limiting magnetic block at the end farther from the conveying main motor is set at a maximum of 180°C.

[0012] Furthermore, the automatic loading type EVA thin sheet baking production process comprises the following steps:

[0013] S1: conveying automation;

[0014] The main conveying motor is started, and the two sets of transmission screws begin to rotate, driving the stabilizing slider to move toward the inside of the baking mechanism on the auxiliary slider. At the same time, the thin plate groove arranged above the stabilizing slider drives the EVA thin plate to be conveyed into the baking mechanism.

[0015] Furthermore, the production process also includes the following steps:

[0016] S2: baking and heating;

[0017] When heating is needed, turn on the baking motor on the baking mechanism, and the heating tube inside the insulation tank obtains electricity and starts to heat up. Under the setting of the air intake hot air duct, the heat is transported to the hot air tank. At the same time, the high-temperature resistant insulation asbestos insulates the internal heat source to prevent the heat source from dissipating too quickly. The hot air tank is aligned with the EVA thin plate on the thin plate tank for heating effect.

[0018] Furthermore, the production process also includes the following steps:

[0019] S3: baking preheating, heating and heat dissipation;

[0020] After the EVA sheet reaches the inside of the baking mechanism, the baking limit electromagnet set on the automation mechanism will attract the upper limit magnetic block of the baking limit mechanism, and the limit magnetic block will move upward on the three-way slide. The limit magnetic block (the temperature rise causes the resistance value of the electromagnet wire circle to increase and the ampere value to decrease. When the temperature of the electromagnet coil changes, the resistance value of the electromagnet coil changes with the temperature coefficient) fits with the baking limit electromagnet to limit the continued rotation of the transmission screw. The EVA sheet inside the sheet slot on the sheet tray stays inside the baking mechanism. After reaching the highest temperature set by the limit magnetic block, the limit magnetic block begins to lose its magnetism, and the limit magnetic block breaks away from the attraction of the baking limit electromagnet and moves downward on the three-way slide, thereby achieving the effect of preheating the EVA sheet.

[0021] Subsequently, the EVA thin sheet inside the thin sheet groove on the transmission screw thin sheet tray continues to move inside the baking mechanism. When the baking limit electromagnet approaches the second group of limit magnetic blocks, the temperature inside the baking mechanism continues to rise at 40°C, and the second group of limit magnetic blocks fit under the attraction of the baking limit electromagnet. When the temperature continues to rise, the hot air groove continues to heat the EVA thin sheet inside the thin sheet groove on the thin sheet tray, thereby achieving the effect of preheating and then heating the EVA thin sheet.

[0022] Then the transmission screw continues to stop rotating. After the temperature reaches the set 180°C, the transmission screw starts to rotate, and the EVA thin sheet inside the thin sheet slot on the thin sheet tray continues to move inside the baking mechanism. At this time, the baking motor on the baking mechanism stops, and the air inlet starts to open, allowing cold air to enter the baking mechanism, and heat is dissipated from the air outlet. After the baking mechanism exits, the EVA thin sheet in the thin sheet slot on the thin sheet tray is slowly cooled to prevent preheating. After heating and rapid heat dissipation, the EVA thin sheet may crack.

[0023] Furthermore, the production process also includes the following steps:

[0024] S4: Automatic discharging;

[0025] After the transmission screw drives the EVA thin plate in the thin plate slot on the thin plate tray to leave the rear baking mechanism, the small motor starts to start, and the stretching slide rod starts to gain power, pulling the stretching cross tooth block to move in the direction of the small motor. At the same time, the rolling gear on the stretching cross tooth block moves in the opposite direction of the stretching cross tooth block. The fixed rod moves in the direction of the rolling gear, driving the thin plate tray above. After the movement, the thin plate tray and the thin plate slot are in a vertical state, and the EVA thin plate on the thin plate slot begins to automatically detach from the thin plate slot, thereby achieving the effect of automatic discharging.

[0026] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: the air inlet of the present invention starts to open, cold air enters into the interior of the baking mechanism, and heat is dissipated from the air outlet. After the baking mechanism exits, the EVA thin plate in the thin plate groove on the thin plate tray is slowly cooled to prevent preheating. After heating, the EVA thin plate is quickly cooled and cracked.

[0027] The fixed rod moves in the direction of the rolling gear, driving the thin plate tray above. After the movement, the thin plate tray and the thin plate slot are in a vertical state, and the EVA thin plate on the thin plate slot begins to automatically separate from the thin plate slot, thereby achieving the effect of automatic discharging.

[0028] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the sheet groove 27 set above the stabilizing slider 13 drives the EVA sheet to be conveyed to the inside of the baking mechanism 3.

[0046] Reference Figure 1-Figure 9 In one embodiment, the automatic feeding type EVA thin sheet baking production equipment includes an automation mechanism 2 including: a small motor 21, which provides power output for the automation mechanism 2; a stretching slide bar 22, which is provided with two groups at both ends of the small motor 21 and is symmetrically and evenly distributed; a stretching cross tooth block 23, which is provided on the stretching slide bar 22 at one end away from the small motor 21; a rolling gear 24, which is meshed and connected to the top of the stretching cross tooth block 23; a fixed rod 25, which passes through the rolling gear 24 and is fixedly connected to another group of rolling gears 24; a thin plate tray 26, which is made of stainless steel and high temperature resistant material and is fixedly connected to the top of the fixed rod 25; a thin plate groove 27, which is provided on the surface of the thin plate tray 26; a baking limit electromagnetic 28, which is provided by the small motor 21 to obtain magnetism and has a maximum high temperature resistance of 200°C.

[0047] Reference Figure 1-Figure 6In one embodiment, the automatic feeding type EVA thin sheet baking production equipment includes a baking mechanism 3 including: a baking motor 31, which provides power output for the baking mechanism 3; a heat preservation tank 32, which is arranged below the baking motor 31 to keep the heat source warm; a heating pipe 33, which is arranged inside the heat preservation tank 32, and provides a heat source for the heat preservation tank 32 under the power output of the baking motor 31; a heat preservation iron sheet 34, which is made of iron and surrounds the baking mechanism 3; a hot air tank 35, which is provided with openings of the same size, and provides a heat source for the inside of the baking mechanism 3; an air inlet 36, which provides the baking mechanism 3 with cold air from the outside; an air inlet hot air duct 37, which provides the heat source inside the heat preservation tank 32 to the hot air tank 35; an air outlet 38, which dissipates the hot air inside the baking mechanism 3 to the outside; a baking limiting tank 39, which is provided with three groups at the bottom of the inside of the baking mechanism 3; and high temperature resistant heat preservation asbestos 310, which is arranged between the hot air tank 35 and the heat preservation iron sheet 34.

[0048] When heating is needed, the baking motor 31 on the baking mechanism 3 is turned on, and the heating pipe 33 inside the insulation groove 32 obtains electricity and starts to generate heat. Under the setting of the air intake hot air duct 37, the hot air groove 35 that transports heat is used. At the same time, the high-temperature resistant insulation asbestos 310 insulates the internal heat source to prevent the heat source from dissipating too quickly. The hot air groove 35 is aligned with the EVA thin plate on the thin plate groove 27 to heat the EVA thin plate.

[0049] Reference Figure 4-Figure 5 In one embodiment, the automatic loading type EVA thin sheet baking production equipment includes a baking limiting mechanism 4 including: a three-way slide 41, which is arranged inside the baking limiting mechanism 4; a three-way slider 42, which is slidably connected on the three-way slide 41; and two groups of limiting magnetic blocks 43 are arranged inside the three-way slide 41.

[0050] Two groups of baking limiting mechanisms 4 are arranged inside the baking mechanism 3. The magnetic temperature of the limiting magnetic block 43 at the end closest to the conveying main motor 11 is set at a maximum of 40°C, and the magnetic temperature of the limiting magnetic block 43 at the end farther from the conveying main motor 11 is set at a maximum of 180°C.

[0051] After the EVA thin plate reaches the inside of the baking mechanism 3, the baking limit electromagnetic 28 set on the automation mechanism 2 will attract the upper limit magnetic block 43 on the baking limit mechanism 4, and the limit magnetic block 43 will move upward on the three-way slide 41. The limit magnetic block 43 (the temperature rise causes the resistance value of the electromagnet wire circle to increase and the ampere value to decrease. When the temperature of the electromagnet coil changes, the resistance value of the electromagnet coil changes with the change of the temperature coefficient) fits with the baking limit electromagnetic 28 to limit the continued rotation of the transmission screw 12. The EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 stays in the baking mechanism 3. After reaching the maximum 40°C set by the limit magnetic block 43, the limit magnetic block 43 begins to lose its magnetism, and the limit magnetic block 43 breaks away from the attraction of the baking limit electromagnetic 28 and moves downward on the three-way slide 41, thereby achieving the effect of preheating the EVA thin plate.

[0052] Subsequently, the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 of the transmission screw 12 continues to move inside the baking mechanism 3. When the baking limit electromagnetic 28 approaches the second group of limit magnetic blocks 43, the temperature inside the baking mechanism 3 continues to rise at 40°C, and the second group of limit magnetic blocks 43 are attached under the attraction of the baking limit electromagnetic 28. When the temperature continues to rise, the hot air groove 35 continues to heat the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26, thereby achieving the effect of preheating and then heating the EVA thin plate.

[0053] Then the transmission screw 12 continues to stop rotating. After the temperature reaches the set 180°C, the transmission screw 12 starts to rotate, and the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 continues to move inside the baking mechanism 3. At this time, the baking motor 31 on the baking mechanism 3 stops, and the air inlet 36 starts to open, and cold air enters the inside of the baking mechanism 3, and heat is dissipated from the air outlet 38. After the baking mechanism 3 exits, the EVA thin plate in the thin plate groove 27 on the thin plate tray 26 is slowly cooled to prevent preheating. After heating, the EVA thin plate is quickly cooled and cracked.

[0054] After the transmission screw 12 drives the EVA thin plate in the thin plate groove 27 on the thin plate tray 26 to leave the rear baking mechanism 3, the small motor 21 starts to start, and the stretching slide rod 22 starts to gain power, pulling the stretching cross tooth block 23 to move in the direction of the small motor 21. At the same time, the rolling gear 24 on the stretching cross tooth block 23 moves in the opposite direction of the stretching cross tooth block 23, and the fixed rod 25 moves in the direction of the rolling gear 24, driving the thin plate tray 26 above. After the movement, the thin plate tray 26 and the thin plate groove 27 are in a vertical state, and the EVA thin plate on the thin plate groove 27 begins to automatically detach from the thin plate groove 27, thereby achieving the effect of automatic discharging.

[0055] Embodiment 2:

[0056] Reference Figure 1-Figure 10 The automatic feeding type EVA thin sheet baking production process is basically the same as that of Example 1, and furthermore:

[0057] S1: conveying automation;

[0058] The main conveying motor 11 is started, and the two sets of transmission screws 12 begin to rotate, driving the stabilizing slider 13 to move toward the inside of the baking mechanism 3 on the auxiliary slider 14. At the same time, the thin plate groove 27 arranged above the stabilizing slider 13 drives the EVA thin plate to be conveyed into the baking mechanism 3.

[0059] S2: baking and heating;

[0060] When heating is needed, the baking motor 31 on the baking mechanism 3 is turned on, and the heating pipe 33 inside the insulation groove 32 obtains electricity and starts to generate heat. Under the setting of the air intake hot air duct 37, the hot air groove 35 that transports heat is used. At the same time, the high-temperature resistant insulation asbestos 310 insulates the internal heat source to prevent the heat source from dissipating too quickly. The hot air groove 35 is aligned with the EVA thin plate on the thin plate groove 27 to heat the EVA thin plate.

[0061] S3: baking preheating, heating and heat dissipation;

[0062] After the EVA thin plate reaches the inside of the baking mechanism 3, the baking limit electromagnetic 28 set on the automation mechanism 2 will attract the upper limit magnetic block 43 on the baking limit mechanism 4, and the limit magnetic block 43 will move upward on the three-way slide 41. The limit magnetic block 43 (the temperature rise causes the resistance value of the electromagnet wire circle to increase and the ampere value to decrease. When the temperature of the electromagnet coil changes, the resistance value of the electromagnet coil changes with the change of the temperature coefficient) fits with the baking limit electromagnetic 28 to limit the continued rotation of the transmission screw 12. The EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 stays in the baking mechanism 3. After reaching the maximum 40°C set by the limit magnetic block 43, the limit magnetic block 43 begins to lose its magnetism, and the limit magnetic block 43 breaks away from the attraction of the baking limit electromagnetic 28 and moves downward on the three-way slide 41, thereby achieving the effect of preheating the EVA thin plate.

[0063] Subsequently, the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 of the transmission screw 12 continues to move inside the baking mechanism 3. When the baking limit electromagnetic 28 approaches the second group of limit magnetic blocks 43, the temperature inside the baking mechanism 3 continues to rise at 40°C, and the second group of limit magnetic blocks 43 are attached under the attraction of the baking limit electromagnetic 28. When the temperature continues to rise, the hot air groove 35 continues to heat the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26, thereby achieving the effect of preheating and then heating the EVA thin plate.

[0064] Then the transmission screw 12 continues to stop rotating. After the temperature reaches the set 180°C, the transmission screw 12 starts to rotate, and the EVA thin plate inside the thin plate groove 27 on the thin plate tray 26 continues to move inside the baking mechanism 3. At this time, the baking motor 31 on the baking mechanism 3 stops, and the air inlet 36 starts to open, and cold air enters the inside of the baking mechanism 3, and heat is dissipated from the air outlet 38. After the baking mechanism 3 exits, the EVA thin plate in the thin plate groove 27 on the thin plate tray 26 is slowly cooled to prevent preheating. After heating, the EVA thin plate is quickly cooled and cracked.

[0065] S4: Automatic discharging;

[0066] After the transmission screw 12 drives the EVA thin plate in the thin plate groove 27 on the thin plate tray 26 to leave the rear baking mechanism 3, the small motor 21 starts to start, and the stretching slide rod 22 starts to gain power, pulling the stretching cross tooth block 23 to move in the direction of the small motor 21. At the same time, the rolling gear 24 on the stretching cross tooth block 23 moves in the opposite direction of the stretching cross tooth block 23, and the fixed rod 25 moves in the direction of the rolling gear 24, driving the thin plate tray 26 above. After the movement, the thin plate tray 26 and the thin plate groove 27 are in a vertical state, and the EVA thin plate on the thin plate groove 27 begins to automatically detach from the thin plate groove 27, thereby achieving the effect of automatic discharging.

[0067] The air inlet 36 of the present invention begins to open, and cold air enters into the interior of the baking mechanism 3, and heat is dissipated from the air outlet 38. After the baking mechanism 3 exits, the EVA thin plate in the thin plate groove 27 on the thin plate tray 26 is slowly cooled to prevent preheating. After heating, the EVA thin plate is quickly cooled and cracked.

[0068] The fixed rod 25 moves in the direction of the rolling gear 24, driving the thin plate tray 26 above. After the movement, the thin plate tray 26 and the thin plate slot 27 are in a vertical state, and the EVA thin plate on the thin plate slot 27 begins to automatically separate from the thin plate slot 27, thereby achieving the effect of automatic discharging.

Automatic feeding type EVA thin sheet baking production process, applied to the automatic feeding type EVA thin sheet baking production equipment according to any one of claims 1 to 6, characterized in that: The production process comprises the following steps: S1: conveying automation; The main conveying motor (11) is started, and the two sets of conveying screws (12) start to rotate, driving the stabilizing slider (13) to move on the auxiliary slider (14) toward the inside of the baking mechanism (3). At the same time, the thin plate groove 27 arranged above the stabilizing slider (13) drives the EVA thin plate to be conveyed into the inside of the baking mechanism (3).

8. The automatic loading type EVA thin sheet baking production process according to claim 7 is characterized in that: The production process also includes the following steps: S2: baking and heating; When heating is required, the baking motor (31) on the baking mechanism (3) is turned on, and the heating pipe (33) inside the heat preservation groove (32) obtains power and starts to generate heat. Under the setting of the air intake hot air pipeline (37), the hot air groove (35) that transports heat is transmitted. At the same time, the high temperature resistant heat preservation asbestos (310) insulates the internal heat source to prevent the heat source from dissipating too quickly. The hot air groove (35) is aligned with the EVA thin plate on the thin plate groove (27) to achieve a heating effect.

9. The automatic loading type EVA thin sheet baking production process according to claim 7 is characterized in that: The production process also includes the following steps: S3: baking preheating, heating and heat dissipation; After the EVA sheet reaches the inside of the baking mechanism (3), the baking limit electromagnetic (28) provided on the automation mechanism (2) will attract the upper limit magnetic block (43) of the baking limit mechanism (4), and the limit magnetic block (43) will move upward on the three-way slide groove (41). The limit magnetic block (43) (the temperature rise causes the resistance value of the electromagnet coil to increase and the ampere value to decrease; when the temperature of the electromagnet coil changes, the resistance value of the electromagnet coil changes with the change of the temperature coefficient) and the baking limit electromagnetic (28) are mutually attached to limit the further rotation of the transmission screw 12. The EVA sheet inside the thin plate groove (27) on the thin plate tray (26) stays inside the baking mechanism (3). After reaching the maximum temperature of 40°C set by the limit magnetic block (43), the limit magnetic block (43) begins to lose its magnetism, and the limit magnetic block (43) is separated from the attraction of the baking limit electromagnetic (28) and moves downward on the three-way slide groove (41), thereby achieving the effect of preheating the EVA sheet. Subsequently, the EVA thin sheet in the thin sheet groove (27) on the thin sheet tray (26) of the transmission screw (12) continues to move inside the baking mechanism (3). When the baking limit electromagnetic (28) approaches the second group of limit magnetic blocks (43), the temperature inside the baking mechanism (3) continues to rise at 40° C. The second group of limit magnetic blocks (43) adheres under the attraction of the baking limit electromagnetic (28). When the temperature continues to rise, the hot air groove (35) continues to heat the EVA thin sheet in the thin sheet groove (27) on the thin sheet tray (26), thereby achieving the effect of preheating and then heating the EVA thin sheet. Then the transmission screw (12) continues to stop rotating. After the temperature reaches the set 180° C., the transmission screw (12) starts to rotate, and the EVA thin plate in the thin plate groove (27) on the thin plate tray (26) continues to move inside the baking mechanism (3). At this time, the baking motor (31) on the baking mechanism (3) stops, and the air inlet (36) starts to open, and cold air enters the inside of the baking mechanism (3). Heat is dissipated from the air outlet (38). After the baking mechanism (3) exits, the EVA thin plate in the thin plate groove (27) on the thin plate tray (26) is slowly cooled to prevent preheating. After heating, the EVA thin plate is quickly cooled and cracked.

10. The automatic loading type EVA thin sheet baking production process according to claim 7 is characterized in that: The production process also includes the following steps: S4: Automatic discharging; After the transmission screw (12) drives the EVA thin plate in the thin plate groove (27) on the thin plate tray (26) to leave the rear baking mechanism (3), the small motor (21) starts to start, the stretching slide rod (22) starts to obtain power, and pulls the stretching cross tooth block (23) to move in the direction of the small motor (21). At the same time, the rolling gear (24) on the stretching cross tooth block (23) moves in the opposite direction of the stretching cross tooth block (23). The fixed rod (25) moves in the direction of the rolling gear (24) to drive the thin plate tray (26) above. After the movement, the thin plate tray (26) and the thin plate groove (27) are in a vertical state, and the EVA thin plate on the thin plate groove (27) starts to automatically detach from the thin plate groove (27), thereby achieving the effect of automatic material discharge.
