Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging cotton winding, more particularly, it relates to a winding and conveying system for EPE composite packaging cotton and a working method thereof. BACKGROUND

[0002] The pearl cotton (also known as polyethylene foamed cotton) is a non-crosslinking closed cell structure, i.e. EPE pearl cotton, which is a new type of environmentally friendly packaging material. The pearl cotton overcomes the shortcomings of ordinary foamed glue, such as fragility, deformation, and poor recovery. The pearl cotton has many advantages, such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, strong anti-collision, and good chemical resistance.

[0003] In the production process of the pearl cotton, butane or the like is usually used as a foaming agent. The process of composite pearl cotton is to composite the single-layer pearl cotton coming from the foaming machine by hot melting or glue. If the tension of the winding material is uneven during winding, the edges of the winding material will not be on a straight line, which affects the winding quality and subsequent use. If there are wrinkles on the surface of the winding material during winding, or the winding speed is unstable, the surface of the winding material cannot be stretched tightly, which will cause the whole or part of the composite pearl cotton to be uneven and wrinkled after winding. This not only occupies more space when the winding material is stored, but also may cause damage to the winding material during transportation due to collision.

[0004] Secondly, the residual butane gas in the foaming agent will form a small pressure inside the pearl cotton. If the butane gas is not fully volatilized, these gases will try to escape under the action of winding pressure and external environmental temperature, which will cause defects such as bubbles and hollows at the composite surface, thereby reducing the quality of the composite product, affecting the overall tightness and firmness, and further affecting the winding quality.

[0005] In addition, butane is also a flammable and explosive gas. In the production environment, if the concentration of butane gas is too high, it will easily cause explosion or fire accidents when encountering fire sources such as sparks and static electricity, which seriously threatens the safety of production personnel and production equipment. Therefore, volatilizing butane gas is an important measure to ensure the safety of the production environment. SUMMARY

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, this is a winding and conveying system for EPE composite packaging cotton according to the first embodiment of the present invention. It should be noted that in this embodiment, "roll 3" refers to EPE pearl cotton. The frame 1 of this system is sequentially equipped with a heating assembly 5, a cutting assembly 6, and a winding assembly 2 according to the transport direction of the roll 3. The heating assembly 5 includes a heating zone 501 for heating the roll 3, and an exhaust assembly for venting gas. The heating assembly 5 heats the roll 3, increasing its surface temperature and accelerating the volatilization of butane gas. The gas volatilized from the roll 3 is discharged through the exhaust assembly, preventing pollution of the working environment. The winding assembly 2 winds up the roll 3. After winding, the cutting assembly 6 cuts the roll 3, facilitating the transport of the roll. Figure 2As shown, the rack 1 is further provided with a first roller body 9, a second roller body 11, a third roller body 12 and a fourth roller body 14 for guiding the coiled material 3 to enter the heating assembly 5, the cutting assembly 6 and the winding assembly 2 in sequence, wherein the inlet 5011 of the heating zone 501 is arranged at the top of one side, and the outlet 5012 is arranged at the bottom of the other side of the heating zone 501, the second roller body 11 and the third roller body 12 are arranged at the inlet 5011 and the outlet 5012 of the heating zone 501 respectively, and the first roller body 9 and the second roller body 11 are provided with a tensioning roller 10 for tensioning the coiled material 3, the structure of the tensioning roller 10 can refer to the tensioning roller disclosed in the patent CN203333047U, which comprises an adjusting roller, the coiled material 3 is arranged on the adjusting roller, the adjusting roller is raised or lowered in the height position by rotating the handle, and the tensioning degree of the coiled material 3 is adjusted, and in the embodiment, an electric telescopic rod is used to drive the tensioning roller 10 to change in the height direction, which can also realize the tensioning effect of the coiled material 3, and the specific process is not described here.

[0038] Then, a flattening roller 13 is arranged between the third roller body 12 and the cutting assembly 6, which is similar to the structure of the tensioning roller 10, and a corresponding auxiliary roller is arranged below the flattening roller 13, on the one hand, the flattening roller 13 is driven by the electric telescopic rod to adjust in the height direction to tension the coiled material 3, and on the other hand, the flattening roller 13 combines with the auxiliary roller below it, that is, the coiled material 3 is pressed on the auxiliary roller by the flattening roller 13, which can improve the surface quality of the coiled material 3 and adjust the uniformity of the thickness of the coiled material 3.

[0039] As shown in the figure, Figure 3 The cutting assembly 6 comprises a gantry support 601 and a knife rest 602, the upper part of the knife rest 602 is provided with a cutting knife body 605, the gantry support 601 is provided with a telescopic device 603, the output end of the telescopic device 603 faces downward and is connected with a knife holder 604, the bottom end of the knife holder 604 is connected with the cutting knife body 605, the end face of one side of the gantry support 601 is vertically provided with a guide column 606, and the two ends of the knife holder 604 are connected with guide sliding blocks 607 matched with the guide column 606. Furthermore, the bottom end of the fourth roller body 14 is arranged flush with the end face of the knife rest 602, and the flattening roller 13 and the fourth roller body 14 are matched, so that when the coiled material 3 passes through the cutting assembly 6, the coiled material 3 floats between the knife rest 602 and the cutting knife body 605, and through appropriate tension adjustment, the coiled material 3 is neither too tight nor too loose, which ensures the stability and accuracy during cutting, that is, avoids uneven cutting caused by being too tight or too loose, and significantly reduces the friction between the coiled material 3 and the knife body or the knife rest 602, further improving the conveying effect of the coiled material 3.

[0040] As shown in the figure, Figure 4 , 5As shown in Figure 6, the winding assembly 2 includes a winding roller 201 and a connector 202. In this embodiment, there are two winding rollers 201. The connector 202 includes an integrally formed connecting shaft 2021 and a connecting block 2022. The connecting shaft 2021 is mounted on the frame 1 via a support base 8. The frame 1 is provided with a power assembly 4 for driving the connecting shaft 2021 to rotate. One end of the winding roller 201 is fixedly connected to the end face of the connecting block 2022. The roll material 3 passes between the two winding rollers 201 and is wound by the rotation of the connector 202. Each winding roller 201 is provided with two spreading parts. The connecting block 2022 is provided with a drive module. The drive module is used to drive the two spreading parts to move synchronously in opposite directions. During the winding process of the two winding rollers 201, when the roll material 3 has wrinkles or bulges, the drive module drives the roll material 3 to rotate. The two spreading sections move synchronously in opposite directions, and the friction between the spreading sections and the roll material 3 is used to spread or eliminate wrinkles. Since double-roller winding is used and the roll material 3 passes between the two winding rollers 201, compared with single-roller winding, double rollers can wind the roll material 3 more quickly and tighten it more easily. Moreover, the force adjustment of the roll material 3 by double rollers and their respective spreading sections can be evenly distributed through the double rollers. If single-roller winding is used, the wound material is generally loose inside and tight outside. In this way, when the spreading section adjusts the tension of the roll material 3, the loose inner layer of the roll material 3 has little effect on the outer layer, and may even make the adjustment of the spreading section ineffective. Therefore, compared with single-roller winding, double-roller winding in this embodiment is more conducive to adjusting the surface tension of the roll material 3 and has a good effect on removing wrinkles on the surface of the roll material 3.

[0041] Next, as Figure 1 As shown, the power assembly 4 includes a first pulley 401 mounted on the connecting shaft 2021 and a reducer 404 mounted on the frame 1. A second pulley 402 is connected to the output end of the reducer 404. The first pulley 401 and the second pulley 402 are connected by a transmission belt 403. The first pulley 401 is connected to the connecting shaft 2021.

[0042] Furthermore, to prevent excessive tension on the roll 3 during winding, which could cause it to tear or break, a damping assembly 7 is provided. The first pulley 401 and the connecting shaft 2021 are connected via the damping assembly 7, as detailed below. Figure 7 and 8As shown, the damping assembly 7 comprises a first felt 701, a second felt 702 and an adjusting bolt 704, the first felt 701 and the second felt 702 are sleeved on the connecting shaft 2021, the first felt 701 is fixedly connected with one side of the first pulley 401, the second felt 702 is axially slidingly and circumferentially fixedly connected with the connecting shaft 2021, and the first felt 701 and the second felt 702 are in surface abutment, the adjusting bolt 704 is threadedly connected with one end of the connecting shaft 2021, and the second spring 703 is sleeved on the connecting shaft 2021 between the adjusting bolt 704 and the second felt 702. The power is transmitted from the speed reducer 404 of the power assembly 4 to the second pulley 402, and then the power of the second pulley 402 is transmitted to the first pulley 401 through the transmission belt 403 to drive the first felt 701 to rotate. The second felt 702 is connected with the connecting shaft 2021 in the form of spline connection, so that the second felt 702 moves along the connecting shaft 2021 in the form of axial sliding and circumferential fixing. Since the first felt 701 and the second felt 702 are in abutment through the second spring 703, the power of the first felt 701 is transmitted to the second felt 702 through friction, and then the second felt 702 drives the connecting shaft 2021 to rotate, so that the connecting head 202 is driven to rotate, and the winding work of the coiled material 3 is realized. Since the rotating state of the connecting shaft 2021 is controlled by the friction between the first felt 701 and the second felt 702, when the winding tension of the coiled material 3 is too large, that is, the tension is greater than the friction between the first felt 701 and the second felt 702, the first felt 701 and the second felt 702 slip, the power between the first felt 701 and the second felt 702 is cut off, and the connecting shaft 2021 stops rotating. When the tension gradually becomes smaller than the friction between the first felt 701 and the second felt 702, the power transmission between the first felt 701 and the second felt 702 is restored, and the connecting shaft 2021 starts to rotate. In this way, the friction between the felts automatically adapts to the different tensions in the winding process of the coiled material 3, avoiding the situation that the coiled material 3 is pulled off due to excessive tension, and achieving the effect of self-adaptation.

[0043] Specifically, as shown in Figure 5 and 6 The expansion part of the embodiment comprises two adjusting pads 205, the inside of the winding roller 201 is provided with a symmetrical screw rod 204 and a first adjusting block 206 corresponding to the adjusting pad 205, the symmetrical screw rod 204 is installed in the winding roller 201 through a fixed seat 207, the first adjusting block 206 is symmetrically arranged on both sides of the fixed seat 207 and threadedly matched with the symmetrical screw rod 204, the winding roller 201 is provided with a guide groove 2011, and the first adjusting block 206 is provided with a protrusion matched with the guide groove 2011, and further as shown in Figure 9 and 10As shown, one end of the inner side of the adjusting pad 205 is provided with an insertion piece 2051, and the other end is provided with a first hook-and-loop fastener 2052. The outer side corresponding to the insertion piece 2051 is provided with a second hook-and-loop fastener 2053. The first hook-and-loop fastener 2052 and the second hook-and-loop fastener 2053 are matched to fix the adjusting pad 205 on the winding roller 201. The protrusion of the first adjusting block 206 is provided with a first insertion slot 2061 for inserting the insertion piece 2051. The driving module is a driver 203, which can be a servo motor. The driver 203 is arranged in the connecting block 2022 and is fixedly connected with one end of the symmetrical screw rod 204. The driver 203 is started to drive the symmetrical screw rod 204 to rotate, so that the first adjusting block 206 on the symmetrical screw rod 204 moves synchronously and reversely. The first adjusting block 206 drives the adjusting pad 205 connected thereto to move reversely. Under the action of friction, the surface of the coiled material 3 can be expanded, and the wrinkles or protrusions on the surface of the coiled material 3 can be eliminated.

[0044] For example Figure 2 As shown, in the present embodiment, the top of the heating area 501 is provided with an air inlet assembly, and the air outlet assembly is arranged at the bottom of the heating area 501. The heating area 501 is internally provided with two rows of roller groups. Each roller group is provided with a plurality of supporting rollers 503. The two sides of the heating area 501 are provided with shaft holes matched with the two ends of the shafts 5031 of the supporting rollers 503. The air inlet assembly comprises an air inlet branch pipe 502. The air inlet branch pipe 502 is provided with an air inlet main pipe 5021 and an air inlet branch pipe 5022. The air inlet branch pipe 5022 is uniformly arranged along the axis of the air inlet branch pipe 502 and extends into the heating area 501 at one end. The air outlet assembly comprises an air outlet branch pipe 504. The air outlet branch pipe 504 is provided with an air outlet main pipe 5041 and an air outlet branch pipe 5042. The air outlet branch pipe 5042 is uniformly arranged along the axis of the air outlet branch pipe 504 and extends into the heating area 501 at one end.

[0045] As Figure 11 As shown, the winding and conveying system for the EPE composite packaging cotton of the second embodiment of the present application is different from the first embodiment in that the winding roller 201 is further provided with a symmetrical screw rod 204 and a second adjusting block 208 corresponding to the adjusting pad 205. Specifically, the symmetrical screw rod 204 is arranged in the winding roller 201 through a fixing seat 207. The second adjusting block 208 is symmetrically arranged on both sides of the fixing seat 207 and is slidably matched with the symmetrical screw rod 204. The first adjusting block 206 is arranged between the adjacent fixing seat 207 and the second adjusting block 208, and the first spring 209 is sleeved on the symmetrical screw rod 204 between the first adjusting block 206 and the second adjusting block 208. The first adjusting block 206 is still threadedly matched with the symmetrical screw rod 204. The first adjusting block 206 and the second adjusting block 208 are both provided with protrusions slidably matched with the guide groove 2011. Figure 9 and 10As shown, one end of the inner vertical surface of the adjusting pad 205 is provided with an insertion piece 2051, and the other end is provided with a first hook-and-loop fastener 2052. A second hook-and-loop fastener 2053 is arranged on the outer vertical surface corresponding to the insertion piece 2051. The first hook-and-loop fastener 2052 and the second hook-and-loop fastener 2053 are adapted to fix the adjusting pad 205 on the winding roller 201. It should be noted that in the present embodiment, the first adjusting block 206 is only provided with a protrusion that is slidingly adapted to the guide groove 2011, and the protrusion of the second adjusting block 208 is further provided with a second insertion groove 2081 for inserting the insertion piece 2051. Similarly, the connecting block 2022 is still provided with a driver 203 that is fixedly connected to one end of the symmetrical lead screw 204. The driver 203 is started to drive the symmetrical lead screw 204 to rotate, thereby synchronously moving the first adjusting block 206 in the opposite direction. Since the first spring 209 is arranged between the adjacent first adjusting block 206 and the second adjusting block 208, when the first adjusting block 206 approaches the second adjusting block 208 and compresses the first spring 209, the first spring 209 has an opening potential. Since the coiled material 3 is wound and wrapped around the adjusting pad 205, the coiled material 3 has a friction force with the adjusting pad 205. If the coiled material 3 has wrinkles or protrusions on the surface, the defect part will consume the potential energy of the first spring 209, thereby automatically eliminating the wrinkles or protrusions. The advantage is that by adjusting the potential energy of the first spring 209, the quality of the surface of the coiled material 3 can be automatically improved. The way of stretching the surface of the coiled material 3 changes from hard pulling to soft pulling, which is friendly to the coiled material 3 and can effectively avoid tearing the coiled material 3 when stretching.

The hot air flow path can be controlled through the first electromagnetic valve 506 and the second electromagnetic valve 507, so that the roller shaft 5031 can enter the coiled material heating scene as needed. It should be noted that the temperature of the hot air is usually room temperature (usually 20-25℃) or slightly higher temperature (30-40℃), and at this temperature, the volatilization effect of butane gas is better.
