Description

Technical Field

[0001] This utility model relates to the field of pearl cotton composite production technology, specifically to a foam pearl cotton board composite device. Background Technology

[0002] Pearl cotton, also known as EPE (expanded polyethylene) foam, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance.

[0003] Existing patent CN201821286490.6 discloses a bubble wrap laminating machine, including a laminating machine body. The laminating machine body includes a frame, a feeding mechanism, a pressing mechanism, a discharging mechanism, and a driving mechanism, all mounted on the frame. The feeding mechanism includes a bubble wrap fixing shaft, a bubble wrap tension roller, a bubble wrap fixing shaft, and a bubble wrap tension roller, all rotatably connected to the frame. The pressing mechanism includes a bubble wrap heating roller, a bubble wrap heating roller, and two pressing rollers, all rotatably connected to the frame. The discharging mechanism includes a composite film roll rod rotatably connected to the frame. The driving mechanism includes two pressing motors and one discharging motor. The pressing motors are drive-connected to the pressing rollers, and the discharging motor is drive-connected to the composite film roll rod. This utility model has a reasonable structural design, good laminating effect, and can effectively avoid adhesion during the laminating process.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment implementation, it is discovered that when applying such equipment to composite connections of pearl cotton sheets of different thicknesses, the distance between the composite pressure rollers cannot be adjusted according to the thickness of the sheet. Therefore, it is not suitable for composite production of pearl cotton sheets of different thicknesses, resulting in low overall structural applicability and certain limitations in use. To address the shortcomings of the existing technology, this utility model proposes a composite device that is applicable to composite production of pearl cotton sheets of different thicknesses. Utility Model Content

[0005] The purpose of this invention is to provide a foam pearl cotton board composite device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam pearl cotton board composite device, comprising a primary frame and a secondary frame, the primary frame and the secondary frame being mirror images of each other. Linear guide grooves are provided inside the bottom ends of both the primary and secondary frames. A ball screw is rotatably mounted in the linear guide groove of the primary frame via bearings. The ball screw is a reversible threaded screw, with threaded blocks threaded onto both its reversible threads. A guide rod is fixedly installed in the linear guide groove of the secondary frame. Two sliding blocks adapted to the threaded blocks are slidably sleeved on the guide rod. A composite roller is rotatably mounted between the two opposing threaded blocks and sliding blocks. A servo motor is fixedly mounted on the outer wall of the bottom end of the primary frame, and the output shaft of the servo motor is connected to the ball screw via a coupling.

[0007] Preferably, two symmetrically distributed primary guide rollers are rotatably installed between the primary frame and the secondary frame, and a secondary guide roller is rotatably installed below the two primary guide rollers and located between the primary frame and the secondary frame.

[0008] Preferably, the distance between the two primary guide rollers is greater than the distance between the two secondary guide rollers.

[0009] Preferably, a hot air hood is fixedly installed between the top of the primary frame and the secondary frame, and two hot air blowers are installed on the hot air hood.

[0010] Preferably, an air outlet cover is fixedly installed on the outside of the air outlet of both hot air blowers.

[0011] Preferably, a lower support is fixedly installed between the lower surfaces of the primary frame and the secondary frame.

[0012] Preferably, a reinforcing rod is connected to the lower support, and anti-slip pads are fixedly installed at the four corners of the bottom of the lower support.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model can change the distance between two composite rollers through the driving effect of positive and negative threads, and has the practical application characteristics of dynamic adjustment of composite distance. The distance size can be dynamically adjusted according to the thickness of different pearl cotton boards, so it can be used for composite processing of pearl cotton boards of different thicknesses. It has good composite size adjustability, more flexible structure, and convenient adjustment. It effectively reduces the limitation of single size use, has a good composite size application range, stronger structural applicability, and simple overall structure, low manufacturing difficulty, and is suitable for use.

[0015] Simultaneously, by dynamically adjusting the spacing between the composite rollers, the composite pressure between the two rollers can be changed. When the two rollers are continuously close together, the composite extrusion pressure on the pearl cotton board continuously increases, while when the rollers are far apart, the composite extrusion pressure on the pearl cotton board continuously decreases until it disappears. Through the use of the above structure, the practical effect of dynamically adjusting the composite extrusion pressure of the rollers can be achieved. The composite pressure on the pearl cotton board can be dynamically adjusted according to different production processes. In actual use, it can effectively improve the composite processing effect, has good structural practicality, meets the composite processing requirements of different process production pressures, and effectively reduces the limitations of use.

[0026] Please see Figure 1-6 The present invention provides an embodiment of a foam pearl cotton board composite device, which includes a primary frame 1 and a secondary frame 2, wherein the primary frame 1 and the secondary frame 2 are arranged in a mirror image opposite each other.

[0027] For details, please refer to the appendix of the instruction manual. Figure 3-5 As shown, linear guide grooves 3 are provided inside the bottom of both the primary frame 1 and the secondary frame 2. A ball screw 4 is rotatably installed in the linear guide groove 3 of the primary frame 1 through a bearing. The ball screw 4 is a forward and reverse threaded screw. Threaded blocks 5 are threadedly connected to both the forward and reverse threads of the ball screw 4. With this structural design, when the ball screw 4 rotates clockwise or counterclockwise, the two threaded blocks 5 threadedly connected to it will move relative to each other, that is, move away from each other or move closer to each other.

[0028] Furthermore, in order to improve the sliding guiding effect, a guide rod 6 is fixedly installed in the linear guide groove 3 of the secondary frame 2. Two sliding blocks 7 that are adapted to the threaded blocks 5 are slidably sleeved on the guide rod 6. A composite roller 8 is rotatably installed between the two opposing threaded blocks 5 and the sliding blocks 7.

[0029] Based on the above structure, when the two threaded blocks 5 move relative to each other under the rotation of the positive and negative ball screws 4, the threaded blocks 5 can drive the composite rollers 8 between them and the sliding block 7 to move, so that the two composite rollers 8 can move relative to each other. At this time, the two composite rollers 8 will move away from each other or move closer to each other. In this way, the distance between the two composite rollers 8 can be changed through the driving effect of the positive and negative threads, which has the practical application characteristics of dynamic adjustment of composite distance.

[0030] In this embodiment, in order to drive the ball screw 4 to perform automated control rotation, a servo motor 9 is fixedly installed on the bottom outer wall of the primary frame 1. The output shaft of the servo motor 9 is connected to the ball screw 4 through a coupling. Thus, the servo motor 9 can drive the ball screw 4 to rotate through its output shaft and the coupling, thereby providing rotational power for the rotation of the ball screw 4.

[0031] In this embodiment, the guiding and feeding process for the two pearl cotton boards before lamination is detailed in the appendix to the instruction manual. Figure 6 As shown, two symmetrically distributed primary guide rollers 10 are rotatably installed between the primary frame 1 and the secondary frame 2, and a secondary guide roller 11 is rotatably installed below the two primary guide rollers 10 and between the primary frame 1 and the secondary frame 2.

[0032] The distance between the two primary guide rollers 10 is greater than the distance between the two secondary guide rollers 11;

[0033] In this structural design, two pearl cotton boards that need to be joined together can enter the device from the left and right sides. Upon entry, the two pearl cotton boards sequentially pass through the primary guide rollers 10 and the secondary guide rollers 11 on both sides, and finally pass between the two composite rollers 8. For a diagram showing the specific feeding direction and path of the pearl cotton boards, please refer to the appendix to the instruction manual. Figure 6 As shown.

[0034] In this embodiment, in order to perform high-temperature hot air melting treatment on the composite bonding surface of the pearl cotton board to facilitate subsequent composite bonding work, a hot air hood 12 is fixedly installed between the top of the primary frame 1 and the secondary frame 2. Two hot air blowers 13 are installed on the hot air hood 12, and air outlet hoods 14 are fixedly installed on the outside of the air outlets of the two hot air blowers 13. The hot air blowers 13 can perform hot air melting on the pearl cotton boards fed from both sides, thereby facilitating subsequent composite bonding treatment.

[0035] In this embodiment, in order to improve the bottom structural stability of the composite device of the present invention, a lower support 15 is fixedly installed between the lower surfaces of the primary frame 1 and the secondary frame 2. The lower support 15 can provide structural support for the bottom of the composite device. A reinforcing rod is connected to the lower support 15, and anti-slip pads are fixedly installed at the four corners of the bottom end of the lower support 15.

[0036] Working principle: In this composite device, two pearl cotton boards that need to be joined together can enter the device from the left and right sides. Upon entry, the two pearl cotton boards sequentially pass through the primary guide rollers 10 and the secondary guide rollers 11 on both sides, and finally pass between the two composite rollers 8, ensuring the subsequent composite effect. The specific feeding direction and path of the pearl cotton boards are shown in the attached diagram of the instruction manual. Figure 6 As shown;

[0037] When the pearl cotton board is laminated, one end is connected to the external unwinding structure and the other end is connected to the external winding mechanism. This unwinding at one end and winding at the other end ensures the winding and conveying of the pearl cotton board and guarantees the normal conveying effect of the pearl cotton board.

[0038] When the pearl cotton board is guided into the primary guide roller 10, a hot air blower 13 is provided at its top. The blower 13 can melt the bonding surface of the pearl cotton board with high temperature hot air, which can facilitate the subsequent panel composite bonding work.

[0039] During the process of the two pearl cotton boards passing through the two composite rollers 8, the two pearl cotton boards can be compositely squeezed by the two composite rollers 8, so that the bonding surface of the two pearl cotton boards can be subjected to pressure to composite bonding, thereby completing the composite processing of the composite device of this utility model and ensuring normal use effect.

[0040] This utility model is equipped with a servo motor 9, which can drive the ball screw 4 to rotate clockwise or counterclockwise. Since the ball screw 4 is a forward and reverse threaded screw, when the ball screw 4 rotates clockwise or counterclockwise, the two threaded blocks 5 connected to it will move relative to each other, that is, move away from each other or move closer to each other.

[0041] When the two threaded blocks 5 move relative to each other under the rotation of the positive and negative ball screws 4, the threaded blocks 5 can drive the composite rollers 8 between them and the sliding block 7 to move, so that the two composite rollers 8 can move relative to each other. At this time, the two composite rollers 8 will move away from each other or move closer to each other. In this way, the distance between the two composite rollers 8 can be changed through the driving effect of the positive and negative threads. It has the practical application characteristics of dynamic adjustment of composite distance. The distance size can be dynamically adjusted according to the thickness of different pearl cotton boards. Therefore, it can be used for composite processing of pearl cotton boards of different thicknesses. It has good composite size adjustability, the structure is more flexible, and the adjustment is convenient. It effectively reduces the limitation of single size use, has a good composite size application range, stronger structural applicability, and the overall structure is simple, the manufacturing difficulty is low, and it is suitable for use.

[0042] Simultaneously, by dynamically adjusting the spacing between the composite rollers 8, the composite pressure between the two composite rollers 8 can be changed. That is, when the two composite rollers 8 are continuously close together, the composite extrusion pressure on the pearl cotton board continuously increases, while when the two composite rollers 8 are far apart, the composite extrusion pressure on the pearl cotton board continuously decreases until it disappears. Through the use of the above structure, the practical effect of dynamically adjusting the composite extrusion pressure of the rollers can be achieved. The composite pressure on the pearl cotton board can be dynamically adjusted according to different production processes. In actual use, it can effectively improve the composite processing effect, has good structural practicality, meets the composite processing requirements of different process production pressures, and effectively reduces the limitations of use.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
