Description

Technical Field

[0001] The utility model relates to the technical field of sponge production, in particular to a sound-absorbing and flame-retardant sponge production shaping device. Background Art

[0002] Sponge is a porous rubber material with a pore structure in which all or most of the pores are connected, and a small number of pores are not connected. During the production and processing of latex sponge, it needs to be cut and shaped.

[0003] The patent application number CN219255652U discloses a fully automatic sponge production and shaping device. The utility model avoids the traditional extrusion cutting method when cutting the sponge by setting the cutting knife in the cutting and shaping mechanism to cooperate with the motor and the driving rod. The cutting blade quickly reciprocates to cut the changing surface, thereby improving the flatness of the sponge shaping cutting surface and also improving the production quality of the sponge after shaping. Secondly, the first cylinder on the lower surface of the other end of the horizontal plate cooperates with the mounting box to adjust the inclination angle of the cutting knife in the sponge cutting and shaping mechanism, thereby expanding the scope of sponge shaping processing and also improving the practicality of the sponge shaping device.

[0004] However, the existing device lacks a device for making multiple groups of holes in the sponge during the production of the sponge to achieve the sound-absorbing and sound-isolating effect of the sponge, which may easily cause the sponge to be inconvenient to use due to the lack of sound insulation or cause nuisance to residents and excessive noise when used later. There is also a lack of a device for rebound detection after production, which may easily lead to defective products after the sponge is shaped, resulting in the sponge being deformed and unable to rebound during later use. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0014] Preferably, a return spring is inserted into the interior of the support leg, and an adjustment button is inserted into one end of the return spring.

[0015] The beneficial effects of the utility model are:

[0016] (1) The utility model achieves the effect of manually placing the sponge on the upper surface of the support plate after the sponge is shaped by the screw motor and the screw, and then the left clamping plate and the right clamping plate are engaged to clamp the sponge for sponge rebound detection, thereby avoiding the problem of the sponge being unable to rebound after deformation when it is inconvenient to use later due to the sponge's unqualified resilience. By placing the plate, the effect of conveniently supporting the sponge and completing the piercing operation is achieved, thereby avoiding the problem of the sponge being pierced and the bottom plate being damaged due to the misoperation when piercing the sponge. By using the air pump and the hydraulic rod, the extrusion plate and the piercing cylinder can be driven to rise or fall. The shaped sponge is pierced with holes to achieve the effect of sound absorption and sound insulation, avoiding the problem that the staff needs to drive the extrusion plate to rise or fall to pierce the shaped sponge. Through the piercing cylinder, the shaped sponge can be pierced with holes quickly to achieve the effect of sound absorption, avoiding the problem that the staff needs to use other tools to pierce holes in the shaped sponge multiple times. Through the fixing seat, the roller can be rotated inside the fixing seat to apply flame retardant to the sponge, avoiding the problem of the roller being offset when using the roller due to the inability to fix the roller.

[0017] (2) The utility model achieves the effect of evenly applying the flame retardant to the shaped sponge through the roller, thus avoiding the problem of the sponge failing to achieve flame retardancy and thus causing combustion and ignition in the later stage, and the problem of the flame retardant failing to be evenly applied to the surface of the sponge and thus causing ignition when it is used later due to the flame retardant not being applied and encountering a fire source through the flame retardant evenly applied to the surface of the sponge. The utility model achieves the effect of conveniently adding the flame retardant to the roller for use through the three-way pipe, thus avoiding the problem of needing to remove the roller before adding the flame retardant to the roller for use. By rotating the motor and the shaft, the sponge raw material before shaping can be added to the mold box and the mold cover can be automatically closed while the sponge raw material is shaped inside, thus avoiding the need for the staff to manually close the mold cover after adding the sponge raw material to the mold box and avoiding the problem of the sponge raw material not being added to the mold box and thus causing inconvenience in shaping.

[0018] (3) The utility model achieves the effect of more quickly shaping the sponge material when the heating plate starts to heat the inside of the mold box after the mold cover is closed by means of the heating plate, thereby avoiding the problem of having to wait for the sponge material to shape itself for a long time due to the inability to heat the inside of the mold box and the problem of workers getting burned when adding the sponge material to the inside of the mold box due to the heating plate being in a heating state for a long time. The utility model achieves the effect of conveniently adjusting the height of the legs inside the leg frame and adjusting the height of the entire device by means of the reset spring and the adjustment button, thereby avoiding the problem of other workers being unable to reach or having to bend over when using the device due to the overall device being too high or too low.

[0031] Embodiment 1

[0032] like Figures 1 to 5As shown, the present embodiment provides a sound-absorbing and flame-retardant sponge production and shaping device, including a bottom plate 1, the left side of the bottom plate 1 is in an arc shape to protect the staff from accidentally bumping into it, a support plate 2 is plugged into the upper surface of the bottom plate 1, a left clamping plate 3 is slidably connected to the upper surface of the support plate 2, a right clamping plate 4 is slidably connected to the upper surface of the support plate 2, a lead screw motor 5 is plugged into the interior of the support plate 2, a lead screw 6 is plugged into one end of the lead screw motor 5, two lead screws 6 are respectively located at both ends of the lead screw motor 5 and rotate in opposite directions to drive the left clamping plate 3 and the right clamping plate 4 to engage or separate, a placement plate 7 is plugged into the upper surface of the bottom plate 1, and the upper surface of the bottom plate 1 The surface is plugged with a baffle 8, and the upper surface of the baffle 8 is provided with a protruding groove into which the telescopic cylinder 9 can be inserted to store the telescopic cylinder 9. The interior of the baffle 8 is plugged with a telescopic cylinder 9, and the interior of the telescopic cylinder 9 is provided with a sliding groove and corresponds to the protruding block structure provided on one side of the telescopic rod 12. The protruding block provided on one side of the telescopic rod 12 can be translated in the sliding groove inside the telescopic cylinder 9 and limit the telescopic rod 12. The interior of the telescopic cylinder 9 is plugged with a hydraulic rod 10, and one side of the hydraulic rod 10 is plugged with an air pump 11. The interior of the telescopic cylinder 9 is slidably connected with the telescopic rod 12, and one end of the telescopic rod 12 is plugged with an extrusion plate 13, and the lower surface of the extrusion plate 13 is plugged with a piercing cylinder 1 4, a fixing seat 15 is inserted on the upper surface of the bottom plate 1, and a roller 16 is connected to the inner rotation of the fixing seat 15. A three-way pipe 17 is inserted on one side of the fixing seat 15, and a mold box 18 is inserted on the upper surface of the bottom plate 1. During use, the lead screw motor 5 and the lead screw 6 can drive the left clamping plate 3 and the right clamping plate 4 to translate on the upper surface of the support plate 2, so that the left clamping plate 3 and the right clamping plate 4 can be engaged to clamp the sponge for sponge rebound detection when the sponge is manually placed on the upper surface of the support plate 2 after the sponge is shaped, thereby avoiding the problem that the sponge cannot rebound after deformation when it is inconvenient to use in the later stage due to the unqualified sponge rebound elasticity. By placing the plate 7. The shaped sponge can be manually placed on the upper surface of the placement plate 7 for use, which can conveniently support the sponge and complete the piercing operation, avoiding the problem of damage to the bottom plate 1 caused by piercing the sponge due to incorrect operation when piercing the sponge. Through the air pump 11 and the hydraulic rod 10, the telescopic rod 12 can be driven to rise or fall inside the telescopic cylinder 9, so that the squeezing plate 13 and the piercing cylinder 14 can be driven to rise or fall to pierce the shaped sponge to achieve the effect of sound absorption and sound insulation, avoiding the problem that the staff needs to drive the squeezing plate 13 to rise or fall to pierce the shaped sponge.

[0033] The piercing cylinder 14 can be used to pierce holes in the shaped sponge, so that the shaped sponge can be pierced quickly to achieve the sound absorption effect, avoiding the problem that the staff needs to use other tools to pierce multiple holes in the shaped sponge. It is worth noting that the number of piercing cylinders 14 is multiple and they are respectively located on the lower surface of the extrusion plate 13, and multiple groups of holes can be pierced in the shaped sponge at the same time. The roller 16 can be supported by the fixing seat 15, so that the roller 16 can be rotated inside the fixing seat 15 to apply the flame retardant to the sponge, avoiding the problem of the roller 16 being offset when using the roller 16 due to the inability to fix the roller 16. The shaped sponge can be manually passed through the middle of the two rollers 16 through the roller 16, so that the flame retardant can be evenly applied to the shaped sponge, avoiding the late combustion due to the failure of the sponge to achieve flame retardancy. The problem of fire and the inability to evenly apply the flame retardant on the surface of the sponge causes the flame retardant to be not applied and encounter a fire source during later use, which causes fire. It is worth noting that there are two rollers 16, which are respectively located in two rotating holes opened inside the fixed seat 15. The interior of the roller 16 is hollow, and the surface of the roller 16 is made of a coating cloth. The flame retardant can be added to the roller 16 and then the flame retardant can penetrate the coating cloth to apply the flame retardant to the sponge. The flame retardant can be manually added to the interior through the three-way pipe 17 and flow into the roller 16, so that the flame retardant can be conveniently added to the roller 16 for use, avoiding the problem that the roller 16 needs to be removed before the flame retardant can be added to the roller 16 for use. It is worth noting that a docking hole is opened on the right side of the roller 16, which can be docked with the three-way pipe 17, and the flame retardant is added to the roller 16 through the docking hole.

[0034] like Figure 5 and Figure 6As shown, a motor seat 19 is plugged into the upper surface of the mold box 18, a rotating motor 20 is plugged into the motor seat 19, a rotating shaft 21 is plugged into one end of the rotating motor 20, a mold cover 22 is sleeved on the surface of the rotating shaft 21, a circular slot is provided on the lower surface of the mold cover 22 to insert the rotating shaft 21, a touch head 23 is plugged into one side of the mold cover 22, a limit block structure is provided on the lower surface of the touch head 23 to be inserted into the limit groove provided in the mold cover 22, a sensor 24 is plugged into the mold box 18, and a heating plate 25 is plugged into the mold box 18. The heating plate 25 can heat the inside of the mold box 18 so that the heat enters the mold box 18 through the heat conducting plate to heat and shape the sponge. A leg frame 26 is plugged into the lower surface of the bottom plate 1. A plurality of plug holes are provided on one side of the leg frame 26 to manually adjust the height of the leg 27. The leg frame 26 is slidably connected to the inside of the leg frame 26. A circular protrusion is provided on the lower surface of the leg 27. The protrusion can increase the supporting area to provide more stable support for the overall device. A reset spring 28 is plugged into the inside of the leg 27. An adjustment button 29 is plugged into one end of the reset spring 28. During use, by rotating the motor 20 and the rotating shaft 21, the mold cover 22 can be driven to fold on the upper surface of the mold box 18, so that the sponge raw material before shaping can be added to the mold box 18 and the mold cover 22 can be automatically covered to shape the sponge raw material inside. This avoids the need for the staff to manually cover the mold cover 22 after adding the sponge raw material to the mold box 18 and avoids the problem that the sponge raw material cannot be added to the mold box 18, resulting in inconvenience in shaping it. Through the heating plate 25, the heating plate 25 can be started to heat the inside of the mold box 18 after the mold cover 22 is covered, so that the sponge raw material can be shaped more quickly when the heating plate 25 starts to heat the inside of the mold box 18 after the mold cover 22 is covered, avoiding the problem that the sponge raw material needs to wait for a long time to shape itself due to the inability to heat the inside of the mold box 18 and the heating plate 25 is in a heating state for a long time, causing the staff to be scalded when adding the sponge raw material to the mold box 18. It is worth noting that after the mold cover 22 is opened, the heating plate 25 automatically turns off the heating function and the staff needs to manually trim the sponge after the sponge raw material is shaped.

[0035] By means of the reset spring 28 and the adjustment button 29, the adjustment button 29 can be manually pressed to adjust the height of the leg 27 inside the leg frame 26, thereby achieving the effect of conveniently adjusting the height of the leg 27 inside the leg frame 26 and adjusting the height of the entire equipment, thereby avoiding the problem that other staff members cannot reach the equipment or need to bend over when using it due to the entire equipment being too high or too low. The entire equipment can be supported by the leg 27, thereby achieving the effect of firmly supporting the entire equipment when the entire equipment is running, thereby avoiding the problem of the entire equipment being displaced due to vibration during operation.

[0036] Working steps

[0037] Step 1. During use, the screw motor 5 and the screw 6 can drive the left clamping plate 3 and the right clamping plate 4 to translate on the upper surface of the support plate 2, so that the sponge can be manually placed on the upper surface of the support plate 2 after the sponge is shaped, and the left clamping plate 3 and the right clamping plate 4 are engaged to clamp the sponge for sponge rebound detection, thereby avoiding the problem that the sponge cannot rebound after deformation when it is inconvenient to use later due to unqualified sponge resilience. The shaped sponge can be manually placed on the upper surface of the placement plate 7 for use through the placement plate 7, so that the sponge can be easily supported. The effect of supporting and completing the piercing operation is avoided, and the problem of damage to the bottom plate 1 caused by piercing the sponge due to misoperation when piercing the sponge is avoided. The telescopic rod 12 can be driven to rise or fall inside the telescopic cylinder 9 through the air pump 11 and the hydraulic rod 10, so that the squeezing plate 13 and the piercing cylinder 14 can be driven to rise or fall to pierce the shaped sponge to achieve the effect of sound absorption and sound insulation, avoiding the problem that the staff needs to drive the squeezing plate 13 to rise or fall to pierce the shaped sponge by themselves. Through the piercing cylinder 14, the shaped sponge can be The holes are punched, so that the shaped sponge can be quickly punched to achieve the sound absorption effect, avoiding the problem that the staff needs to use other tools to punch holes in the shaped sponge. The fixed seat 15 can support the roller 16, so that the roller 16 can be rotated inside the fixed seat 15 to apply the flame retardant to the sponge, avoiding the problem that the roller 16 is offset when the roller 16 is used due to the inability to fix the roller 16. The shaped sponge can be manually passed through the middle of the two rollers 16 through the roller 16 to achieve The flame retardant can be evenly applied to the shaped sponge, avoiding the problem of combustion and fire in the later stage due to the failure of the sponge to achieve flame retardancy and the failure to evenly apply the flame retardant on the surface of the sponge, resulting in the flame retardant not being applied and encountering a fire source during later use, thereby achieving the effect of conveniently adding the flame retardant to the roller 16 for use, avoiding the problem of removing the roller 16 before adding the flame retardant to the roller 16 for use when the flame retardant is needed.

[0038] Step 2: During use, the motor 20 and the rotating shaft 21 are rotated to drive the mold cover 22 to be folded on the upper surface of the mold box 18, so that the sponge raw material before shaping can be added to the mold box 18 and the mold cover 22 is automatically covered, and the sponge raw material is shaped and processed inside. This avoids the problem that the staff needs to manually cover the mold cover 22 after adding the sponge raw material to the mold box 18 and avoids the problem that the sponge raw material cannot be added to the mold box 18, resulting in inconvenience in shaping. Through the heating plate 25, the heating plate 25 can be started to heat the inside of the mold box 18 after the mold cover 22 is covered, so that the sponge raw material can be shaped more quickly when the heating plate 25 starts to heat the inside of the mold box 18 after the mold cover 22 is covered, and avoids the problem that the sponge raw material cannot be heated inside the mold box 18. The heating requires a long time to wait for the sponge raw material to be shaped by itself, and the heating plate 25 is in a heated state for a long time, which causes burns to the staff when adding the sponge raw material into the mold box 18. The reset spring 28 and the adjustment button 29 can be manually pressed to adjust the height of the leg 27 inside the leg frame 26, so that the height of the leg 27 inside the leg frame 26 can be easily adjusted and the height of the entire equipment can be adjusted. The problem that other staff cannot reach or need to bend over when using the equipment due to the entire equipment being too high or too low is avoided. The entire equipment can be supported by the legs 27, so that the entire equipment can be firmly supported when it is running, and the problem of the entire equipment being offset due to vibration during operation is avoided.
