Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic feeding device and an automatic material collecting device in a production line for producing sound insulation and noise reduction foaming materials. Background Art

[0002] Sound insulation and noise reduction materials are used in various places or equipment. Such materials include common foaming cotton, which is produced by a special production line. The production line includes a foaming process, that is, foaming processing is carried out in the foaming equipment of the production line. Currently, the common practice is to place the foaming material in a heated long-distance foaming channel. The cross-section of the channel is square and there are slits along the length direction in its two side walls. After the foaming material is heated to a certain temperature, it starts to foam and expand. During the expansion process, part of the foaming cotton enters the slits and is squeezed and rubbed against the side inner walls of the channel, resulting in the upward expansion amplitude of the foaming cotton in contact with the two sides of the channel being smaller than that of the foaming cotton in the middle. Finally, the foaming cotton in the middle reaches the top of the foaming channel, forming an arc-shaped top, that is, the foaming cotton cannot fill the foaming channel, resulting in low foaming utilization rate. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an automatic feeding and material collecting system.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: an automatic feeding and material collecting system, including at least one set of feeding device and a material collecting device cooperating with it; the feeding device includes: a feeding frame, a feeding turning device installed on it for feeding, a new and old film belt connection device installed on the feeding frame, a pressing device for pressing the film belt, a film belt buffer device, a film belt cutting device and a tensioning device; the new and old film belt connection device is in the next process after the pressing device; the film belt from the feeding turning device passes through the pressing device, the new and old film belt connection device, and the film belt buffer device workstations in sequence and then is sent out through the tensioning device; the material collecting device includes: a material collecting frame, a material collecting turning device installed on it for material collecting, a waste film belt winding device installed on the material collecting frame, a waste film belt pressing mechanism for pressing the waste film belt, a waste film belt buffer device, a waste film belt cutting device and a waste film belt tensioning device; the film belt from the tensioning device is connected to the waste film belt tensioning device after use, and then passes through the waste film belt buffer device, the waste film belt pressing mechanism, and the waste film belt cutting device workstations in sequence and is wound and discarded through the material collecting turning device.

[0005] Technical effect: The system of the present utility model includes four sets of feeding and receiving devices, which are adapted to the shape of the foaming channel of the foamed cotton production line. The feeding device is located at the front end of the foaming channel, while the receiving device is located at the rear end of the foaming channel. The feeding device connects the released roll-shaped film tape to the winding structure on the receiving device. During the feeding and receiving process, the film tape passes through the foaming channel and fits against its inner wall. That is, the new film tape released by the feeding device is wound up and discarded by the receiving device after passing through the foaming channel. By setting four sets of feeding and receiving devices, the released film tapes enclose a channel with a shape adapted to the shape of the foaming channel. The foaming material is placed on the film tape. During the heating and foaming process, after the foaming material expands, it does not directly contact the inner wall of the foaming channel, so it is not affected by the foaming channel, and thus can fill the space enclosed by the film tape and move out of the foaming channel along with the movement of the film tape to enter the next process, while the film tape passing through the foaming channel is wound up. Compared with the prior art, the present utility model is beneficial to improving the efficiency of foaming processing. Brief Description of the Drawings

[0049] In order to enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] The embodiment of the present utility model provides an automatic feeding and collecting system, which is used in a foamed cotton production line and includes at least one set of feeding device and a collecting device cooperating therewith. Specifically, the number of feeding and collecting devices used is determined according to actual needs. For example, in order to adapt to the current production line, four sets of devices are required to form a feeding and collecting system. Each set of devices includes a feeding device and a collecting device, and the two can be set in a complete set; as Figure 1-2 shown.

[0051] As Figures 41-43 shown, the feeding device includes: a feeding frame 1, a feeding turning device 2 for feeding installed thereon, a new and old film belt connection device 3 installed on the feeding frame, a pressing device 4 for pressing the film belt, a film belt buffer device 5, a film belt cutting device 6 and a tensioning device 7; during assembly, the new and old film belt connection device 3 is located in the subsequent process of the pressing device 4; the film belt from the feeding turning device 2 passes through the pressing device 4, the positions where the new and old film belt connection device 3 is located and the station where the film belt buffer device is located in sequence and then is sent out through the tensioning device 7; the collecting device includes: as Figures 27-30 shown, a collecting frame 8, a collecting turning device 9 for collecting installed thereon, a waste film belt winding device 10 installed on the collecting frame, a waste film belt pressing mechanism 11 for pressing the waste film belt, a waste film belt buffer device 12, a waste film belt cutting device 13 and a waste film belt tensioning device 17; the film belt after use from the tensioning device 7 is connected to the waste film belt tensioning device 17, and then passes through the station where the waste film belt buffer device 12 is located and the positions where the waste film belt pressing mechanism 11 and the waste film belt cutting device 13 are located in sequence and is then wound by the collecting turning device and discarded.

[0052] As Figure 1-2 shown, the feeding device further includes a left and right deviation rectifying device 14 installed on the feeding frame; the collecting device further includes a waste material winding deviation rectifying device 15 installed on the collecting frame.

[0053] As Figures 3-4 、 Figure 23As shown, the feeding frame 1 includes a supporting bottom plate 101, a movable supporting plate 102 movably arranged on its outer surface, two feeding support columns 103 respectively arranged at both ends of the outer surface of the movable supporting plate, and a gantry bracket 104 located on one side of the two feeding support columns. With this structure, the supporting bottom plate 101 is fixed on the ground or other positions, and the movable supporting plate 102 can move on the supporting bottom plate.

[0054] As Figures 3-9 shown, the feeding turning device 2 includes a turning main shaft 201 with both ends respectively hinged to the free ends of the two feeding support columns 103, two feeding mounting plates 202 respectively arranged at both ends of the turning main shaft and perpendicular to it, a first feeding assembly and a second feeding assembly arranged between the two feeding mounting plates and connected to both of them, a turning motor 203 arranged on the outer surface of the movable supporting plate 102 and a turning driving wheel 204 connected to its output end, a turning linkage shaft 205 with both ends respectively vertically connected to one end of the two feeding support columns connected to the movable supporting plate 102, that is, the connection positions of both ends of the turning linkage shaft 205 with the two feeding support columns are located at the positions where the two feeding support columns 103 are connected to the movable supporting plate 102; a turning driven wheel 206 fixed on the turning linkage shaft, two sub-driven wheels 207 respectively arranged at both ends of the turning main shaft 201 and located outside the two feeding support columns, two sub-synchronous wheels 208 respectively arranged at both ends of the turning linkage shaft 205 and located outside the two feeding support columns, a first synchronous belt 209 for connecting the turning driving wheel and the turning driven wheel, and two second synchronous belts 210 respectively for connecting the two groups of sub-synchronous wheels and the sub-driven wheels.

[0055] As Figures 3-9As shown, the first material feeding component and the second material feeding component adopt the same structure, but their installation positions are different. The first material feeding component includes: a material feeding motor 211 provided on the inner side of one of the material feeding mounting plates 202, two rotating connection parts 212 provided on the two material feeding mounting plates, a material feeding linkage shaft 213 with both ends hinged to the two material feeding mounting plates respectively and located outside the two plates, a material feeding driving wheel 214 located outside the material feeding mounting plate where the material feeding motor 211 is installed and connected to the output end of the material feeding motor, two material feeding driven wheels 215 respectively provided outside the two material feeding mounting plates 202 and connected to the two rotating connection parts 212 respectively, two material feeding synchronous wheels 216 respectively connected to both ends of the material feeding linkage shaft 213 and located outside the two material feeding mounting plates 202, a material feeding synchronous belt 217 for connecting the material feeding driving wheel 214, the material feeding driven wheels 215 and the material feeding synchronous wheels 216, and a first material feeding synchronous belt 218 for connecting the material feeding driven wheels 215 and the material feeding synchronous wheels 216; a joint plate 219 with both ends connected to the two material feeding mounting plates 202 respectively for adhering the joint of the film tape, and a material feeding support roller 220 with both ends connected to the two material feeding mounting plates 202 respectively for tensioning the film tape; the material feeding support roller 220 and the joint plate 219 are respectively located on both sides of the material feeding linkage shaft 213 and the three are parallel to each other; the material feeding roll is located between the two material feeding mounting plates 202 and both ends thereof are detachably connected to the two rotating connection parts 212 respectively for replacing the spare material feeding roll; in the first material feeding component and the second material feeding component, one of the components is in the material feeding station and the other is in the standby station. When the flipping main shaft drives the two material feeding mounting plates to rotate 180 degrees, the positions of the two can be swapped.

[0056] With the above structure, in the first material feeding component and the second material feeding component, each component includes a material feeding roll. One of the components is in the material feeding station and the other is in the standby station. As Figures 8-12In the shown arrangement, the lower material feeding component is at the material feeding station, and the upper one is at the standby station. At this time, the material feeding motor 211 at the material feeding station starts, drives the material feeding driven wheel 215 and the material feeding synchronous wheel 216 to rotate through the material feeding synchronous belt 217, and then drives the two rotating connection parts 212 to rotate. The material feeding roll connected to the two rotating connection parts 212 at both ends rotates accordingly, that is, the material feeding operation is carried out. At the same time, a material feeding roll is placed at the standby station for standby. One end of the material feeding roll is pulled out and attached to the surface of the joint plate 219 of the material feeding component. When the material feeding roll at the material feeding station needs to be replaced, the flipping motor 203 is started, which drives the flipping driving wheel 204, the flipping linkage shaft 205, the flipping driven wheel 206, the auxiliary synchronous wheel 208, and the auxiliary driven wheel 207 to rotate in sequence. The flipping main shaft 201 rotates accordingly, and the two material feeding mounting plates 202 provided at both ends of the flipping main shaft rotate accordingly, so as to drive the first material feeding component and the second material feeding component to exchange positions. That is, when the flipping main shaft drives the two material feeding mounting plates to rotate 180 degrees, their positions can be swapped. The full material feeding roll at the preparatory station rotates to the material feeding station for the material feeding operation, the empty material feeding roll is taken down and a new material feeding roll is replaced, and at the same time, one end of the new material roll is pulled out and fixed on the surface of the joint plate 219 of the standby material feeding component for standby.

[0057] As Figures 13-16 Shown in the figure, the new and old film belt connection device 3 includes two lifting roller lifting cylinders 301 provided on the movable support plate 102, and a lifting mounting plate 302 connected to both ends of the two lifting roller lifting cylinders and moving up and down with them. That is, both ends of the lifting mounting plate 302 here are connected to the lifting parts of the two lifting roller lifting cylinders 301 and move up and down with them; two transverse guide rails 303 respectively provided on the two lifting roller mounting platforms, two transverse sliding blocks 304 movably arranged on the two transverse guide rails, a transverse mounting plate 305 fixedly connected to the back surfaces of both ends of the two transverse sliding blocks, a lifting roller 306 provided on the front surface of the transverse mounting plate, and two transverse cylinders 307 provided on the lifting mounting plate 302. Here, the lifting mounting plate is located between the transverse mounting plate 305 and the movable support plate 102; the telescopic ends of the transverse cylinders 307 are connected to the back surface of the transverse mounting plate 305, and the two transverse cylinders are located between the two lifting roller lifting cylinders 301.

[0058] Here, the lifting roller 306 is located on one side of the joint plate 219. According to Figures 8-12In the shown arrangement, the lifting roller 306 is located below the joint plate 219. When the spare material roll at the spare station rotates to the unwinding station, the material roll at the original unwinding station rotates to the spare station. At this time, the film tape in the unwinding state extends to the spare station, and the film tape in the unwinding state is located below the joint plate 219, that is, below one end of the new film tape on the joint plate 219. At this time, the two lifting roller lifting cylinders 301 are activated, and the lifting roller 306 rises. First, one end of the new film tape is brought into contact with the film tape in the unwinding state (old film tape). In order to make the two fit more tightly and firmly, the transverse movement cylinder 307 is then activated to push the lifting roller 306 to translate a certain distance, so that the new film tape and the film tape in the unwinding state (old film tape) are in contact with each other for a longer length; As Figure 37 shown, for the convenience of understanding, in the figure, Material A refers to the new material roll to be replaced, and Material B refers to the old material roll to be replaced.

[0059] As Figures 10-12 shown, the pressing device includes a first pressing plate assembly and a second pressing plate assembly, and their structures are the same; the first pressing plate assembly includes two first pressing plate cylinders 401 arranged in a line, two first pressing plate vertical plates 402 respectively located outside them, two first pressing plate guide rails 403 respectively arranged on the two first pressing plate vertical plates, two first pressing plate sliders 404 respectively movably arranged on the two first pressing plate guide rails, two first sliding plates 405 respectively fixedly connected to the backs of the two first pressing plate sliders, and a first pressing plate 406 fixedly connected to the ends of the backs of the two first sliding plates at both ends; the telescopic rods of the two first pressing plate cylinders 401 are fixedly connected to the back of the first pressing plate 406; the first pressing plate cylinders 401 and the first pressing plate vertical plates 402 are both fixedly arranged on the movable support plate 102. Here, the first pressing plate assembly is located on one side of one of the unwinding support rollers 220. When the material roll at the unwinding station needs to be replaced, after the material roll at the unwinding station rotates to the spare station, the first pressing plate cylinder 401 here is activated to drive the first pressing plate 406 to extend and contact and clamp the film tape in the unwinding state with the unwinding support roller 220.

[0060] As Figures 17-19As shown in the figure, the film strip buffer device 5 includes a buffer motor 501 disposed on the movable support plate 102 and a buffer speed reducer 502 disposed at its output end, a buffer driving wheel 503 connected to the buffer speed reducer 502, a buffer lifting linkage shaft 504 disposed on the movable support plate 102 and outside the gantry support 104, a buffer driven wheel 505 sleeved on the buffer lifting linkage shaft, a buffer synchronous belt 506 for connecting the buffer driving wheel and the buffer driven wheel, two lifting driving wheels 512 respectively disposed at both ends of the buffer lifting linkage shaft 504, two lifting driven wheels 507 disposed on the outer side surfaces of the ends of the gantry support 104 and corresponding to the two lifting driving wheels 512 respectively, and two lifting synchronous belts 508 respectively for connecting the two groups of lifting driving wheels 512 and lifting driven wheels 507. That is, one lifting driving wheel 512 and the lifting driven wheel 507 on the same side here form a group, and the two are connected by a lifting synchronous belt 508; a buffer roller mounting plate 509 fixedly connected to the two lifting synchronous belts 508 at both ends and parallel to the buffer lifting linkage shaft 504, a buffer roller 510 disposed on the buffer roller mounting plate, and a pressing roller 511 respectively connected to the gantry support 104 at both ends and located inside the buffer lifting linkage shaft.

[0061] As Figure 17 shown, the second pressing plate assembly 4a is located on one side of the pressing roller 511, and its structure is the same as that of the first pressing plate assembly. Please refer to Figures 10-12 shown. When the material roll needs to be replaced, after the material roll at the feeding station rotates to the standby station, the pressing plate cylinder (the same as the first pressing plate cylinder 401) of the second pressing plate assembly is activated, driving the corresponding pressing plate (the same as the first pressing plate 406) to extend out, contacting and clamping the film strip in the feeding state with the pressing roller 511. That is, when replacing the material roll, two positions of the film strip in the feeding state are clamped and cannot move, so that one end of the new film strip can be attached to the film strip (old film strip) in the feeding state.

[0062] With the film belt buffer device 5, when the feeding roll needs to be replaced, since the new feeding roll and the old feeding roll need to be connected, therefore, neither of them can continue to feed the material. However, at this time, the feeding still needs to be carried out and the machine cannot be stopped for replacement. When the tension of the film belt between the tensioning device 7 and the film belt buffer device 5 remains unchanged, the buffer motor 501 is started. It drives the buffer driving wheel 503, the buffer lifting linkage shaft 504, the buffer driven wheel 505, the lifting driving wheel 512, and the lifting driven wheel 507 to rotate in sequence. The lifting synchronous belt 508 moves accordingly. The buffer roller mounting plates 509 fixedly connected to the two lifting synchronous belts 508 at both ends and the buffer rollers 510 provided on the buffer roller mounting plates 509 descend, releasing the film belt tensioned by the buffer rollers 510 until the operation of replacing the feeding roll is completed. Then the buffer motor 501 rotates in the reverse direction to buffer the film belt again for standby. Obviously, in the initial state, the buffer rollers 510 are generally located at positions close to the ends of the gantry bracket 104 so that the buffered film belt is sufficient for use when replacing the feeding roll.

[0063] As Figures 10-12 shown, the film belt cutting device 6 includes a cutter module cylinder provided on the inner side surface of the first pressing plate 406. It selects a commercially available standard slide cylinder, on which there is a cylinder slide block 601, and a cutter 602 connected to the cylinder slide block. That is, the cutter 602 is provided on the cylinder slide block 601. When it moves on the cutter module cylinder, it can drive the cutter 602 to move horizontally along the first pressing plate 406 to cut the film belt. Here, two cylinder slide blocks 601 are shown in the figure, only showing the movable range of the cylinder slide blocks, not indicating that the cutter module cylinder includes two cylinder slide blocks 601; when replacing the feeding roll, when the standby roll in the standby station rotates to the feeding station, the roll in the original feeding station rotates to the standby station. At this time, the film belt in the feeding state extends to the standby station accordingly. Then the first pressing plate cylinder 401 is started to drive the first pressing plate 406 to extend and contact and clamp the film belt in the feeding state with the feeding support roller 220. At the same time, the pressing plate cylinder of the second pressing plate assembly (the same as the first pressing plate cylinder 401) is started to drive the corresponding pressing plate (the same as the first pressing plate 406) to extend and contact and clamp the film belt 19 in the feeding state with the pressing roller 511; the two lifting roller lifting cylinders 301 are started, and the lifting rollers 306 rise first to make one end of the new film belt fit together with the film belt in the feeding state (the old film belt); the cutter module cylinder is started to drive the cutter 602 connected to it to move horizontally and cut the material belt behind the feeding support roller 220, and the new feeding roll replaced to the feeding station starts to feed the material; As Figure 41 shown.

[0064] As Figures 20-22As shown in the figure, the tensioning device 7 includes a feeding tensioning bracket 701 connected to one side of the gantry bracket 104 provided on the movable support plate 102, and a tensioning roller assembly provided thereon and located outside the buffer roller 510; the tensioning roller assembly includes a first tensioning roller 702, a second tensioning roller 703, a third tensioning roller 704 and a fourth tensioning roller 705 that are parallel to each other. The second tensioning roller is installed on a tensioning roller base 706 located between the first and third tensioning rollers, and a tension sensor 707 is provided at the bottom of the second tensioning roller on the tensioning roller base; in the tensioning roller assembly, the first tensioning roller is closer to the buffer roller 510, and the other tensioning rollers are relatively farther away from the buffer roller. The tension sensor 707 here is communicatively connected to an external tension controller (PLC controller). The film tape on the unwinding reel passes through the film tape buffer device 5 in sequence and then reaches the tensioning device 7, and then is sent out by the tensioning device 7. That is, the film tape between the tensioning device 7 and the unwinding reel is in a tensioned state. The tension sensor 707 sends the detected tension signal to the tension controller, which controls the rotation speed of the unwinding motor 211, thereby controlling the magnitude of the tension to make it conform to the set tension value; when it is detected that the tension is too large, that is, the film tape is too tight, the rotation speed of the unwinding motor 211 increases to accelerate the unwinding speed, and vice versa, the unwinding speed is reduced.

[0065] As Figures 23-26 shown in the figure, the left and right deviation rectifying device 14 includes two sets of deviation rectifying guide rails 1401 provided on the support bottom plate 101. Each set of deviation rectifying guide rails includes two mutually parallel deviation rectifying single rails, and a number of movable deviation rectifying sliders 1402 provided on each deviation rectifying single rail and fixedly connected to the back of the movable support plate 102; a deviation rectifying servo motor 1403 provided on the support bottom plate 101, a deviation rectifying lead screw 1404 connected to the output end of the deviation rectifying servo motor and installed on the support bottom plate 101, a deviation rectifying nut 1405 movably provided on the deviation rectifying lead screw, and a deviation rectifying connecting block 1406 connected to the deviation rectifying nut and the back of the movable support plate 102; a deviation rectifying sensor bracket 1407 provided on the support bottom plate 101, and a deviation rectifying sensor 1408 provided on it (the deviation rectifying sensor bracket) and located outside one end of the tensioning roller assembly; the deviation rectifying lead screw 1404 is parallel to the deviation rectifying guide rails 1401 and the tensioning roller assembly. When the film tape is sent out through the tensioning device 7, it is necessary to ensure that the film tape passes through the deviation rectifying sensor 1408. When the film tape deviates, the deviation rectifying servo motor 1403 is started to drive the deviation rectifying lead screw 1404 to rotate, and the deviation rectifying nut 1405, the deviation rectifying connecting block 1406 and the movable support plate 102 move left and right accordingly, driving the tensioning device 7 on the movable support plate to move left and right, so that the film tape always passes through the deviation rectifying sensor 1408.

[0066] As Figures 27-30As shown, the receiving rack 8 is the same as the feeding rack 1. For the convenience of understanding, a brief description is given here again. It includes a receiving support bottom plate (not shown, the same as the support bottom plate 101), a movable receiving support plate 802 movably arranged on its outer surface, two receiving support columns 803 for installing the receiving turnover device 9 respectively arranged at both ends of the outer surface of the movable receiving support plate, and a receiving gantry bracket 804 located on one side of the two receiving support columns.

[0067] As Figures 31-34 shown, the waste film belt winding device 10 includes two receiving lifting roller lifting cylinders 1001 arranged on the movable receiving support plate 802, a receiving lifting roller mounting plate 1002 with both ends respectively connected to the two (the two receiving lifting roller lifting cylinders) and moving up and down with them, two mutually parallel receiving lifting rollers 1003 with both ends respectively fixedly connected to two fixed brackets 1002a fixed on the receiving lifting roller mounting plate, two groups of lifting vertical rails, each group of vertical rails including two receiving lifting guide rails 1004, and receiving lifting sliders 1005 movably arranged on each receiving lifting guide rail; the receiving lifting sliders of the two groups of lifting vertical rails are respectively fixedly connected to both ends of the receiving lifting roller mounting plate 1002; the two groups of lifting vertical rails are fixedly connected to the receiving support bottom plate and are respectively located outside both ends of the receiving lifting roller mounting plate 1002;

[0068] As Figures 35-36 shown, the waste film belt pressing mechanism 11 includes two receiving pressing plate cylinders 1101 arranged in a line, two receiving pressing plate vertical plates 1102 respectively located outside the two, two receiving pressing plate guide rails 1103 respectively arranged on the two receiving pressing plate vertical plates, two receiving pressing plate sliders 1104 respectively movably arranged on the two receiving pressing plate guide rails 1103, two receiving sliding plates 1105 with their backs respectively fixedly connected to the two receiving pressing plate sliders 1104, and a receiving pressing plate 1106 with both ends of its back respectively fixedly connected to the ends of the two receiving sliding plates 1105; the telescopic rods of the two receiving pressing plate cylinders 1101 are fixedly connected to the back of the receiving pressing plate 1106; here, the receiving pressing plate cylinders 1101 and the receiving pressing plate vertical plates 1102 are both fixedly arranged on the movable receiving support plate 802.

[0069] As Figures 37-40 shown, in the receiving device, the structure of the waste film belt buffer device 12 is exactly the same as that of the film belt buffer device 5. It is used for buffering during the process of winding the waste film belt, that is, providing the waste film belt 20 to be wound when replacing the waste film belt receiving roll, so that the waste film belt receiving roll can be replaced without stopping the winding process; As Figures 39-40As shown, the waste film belt cutting device 13 has the same structure as the film belt cutting device 6. It is arranged on the material receiving pressing plate 1106 and is used to cut the waste film belt during the process of replacing the waste film belt receiving roll, thereby completing the replacement of the waste film belt receiving roll; the waste film belt tensioning device 17 and the tensioning device 7 have the same structure respectively, and it is used to tension the waste film belt being wound during the winding process of the waste film belt.

[0070] The left and right deviation rectifying devices 14 during the unwinding process and the waste material winding deviation rectifying device 15 in the material receiving device have the same structure. The only difference is that the waste material winding deviation rectifying device 15 installs the deviation rectifying sensor bracket and the deviation rectifying sensor on the movable material receiving support plate 802, that is, the deviation rectifying sensor here can move along with the waste film belt, so that during the winding process, both ends of the waste film belt roll are kept neat. That is to say, during the material receiving process, the state of the waste film belt from the foaming station cannot be adjusted. In order to keep both ends of the waste film belt roll neat during the winding process of the waste film belt, it is assumed that the positions on both sides of the waste film belt are fixed without deviation. If the waste film belt always passes through the waste film belt deviation rectifying sensor 1501, the waste material winding deviation rectifying device 15 and the material receiving winding drum 18 remain stationary. When the waste film belt has a deviation, the waste material winding deviation rectifying device 15 is activated, and the movable material receiving support plate 802 moves in the same way as the movable support plate 102, driving the waste film belt deviation rectifying sensor 1501 and the material receiving winding drum 18 to follow the waste film belt, so that both ends of the wound waste film belt roll are kept neat.

[0071] As Figures 27-30 As shown, actually, the material receiving turning device 9 and the unwinding turning device 2 are basically the same in structure. The only difference is that in the first unwinding component and the second unwinding component of the unwinding turning device 2, in order to adhere the joint of the new film belt, they also include a joint plate 219. However, the connection method of the new and old waste film belts of the material receiving turning device 9 is different from the connection of the new and old film belts, so there is no need to set up a joint plate 219.

[0072] As Figure 37As shown, after the film tape from the feeding device passes through the foaming production station, it becomes a waste film tape, which is wound up by the receiving device and discarded; here, the waste film tape passes through the waste film tape tensioning device 17 and the waste film tape buffer device 12 in sequence and then reaches the winding station. Here, the receiving reel 18 (which can be taken and placed like the feeding reel) on the receiving turnover device 9 winds up the waste film tape under the drive of the receiving motor (which is the same as the feeding motor 211, only with a different rotation direction). There is also a spare empty receiving reel on the receiving turnover device 9. When the waste film tape on the receiving reel at the receiving station is wound to a certain thickness, the receiving reel needs to be replaced. Similar to the operation of the feeding turnover device 2, the spare empty receiving reel is rotated to the receiving station, and the receiving reel that has completed the receiving is rotated to the spare position, that is, their positions are exchanged. At this time, the waste film tape is not cut off and naturally extends to the spare position, and the waste film tape is located on one side (or below) of the empty receiving reel; at this time, two receiving pressure plate cylinders 1101 arranged in a line start, driving the receiving pressure plate 1106 to contact and press the waste film tape against the receiving support roller (the same as the feeding support roller 220) on the receiving turnover device 9. Then, the receiving lifting roller lifting cylinder 1001 starts, driving the two receiving lifting rollers 1003 to extend, and pushing the waste film tape extending to the spare position to stick tightly to the empty receiving reel 18. Since the surface of the empty receiving reel is coated with glue, the waste film tape is connected to the receiving reel. Then, the waste tape cutting knife module cylinder (the same as the cutting knife module cylinder) of the waste film tape cutting device 13 is started to drive the cutting knife connected to it to cut off the waste film tape. In this process, the operation principle of the waste film tape buffer device 12 is exactly opposite to that of the film tape buffer device 5. When replacing the feeding reel during feeding, it is necessary to release the film tape in the film tape buffer device 5, so the buffer roller 510 needs to continuously descend. During the receiving process, when replacing the receiving reel, because the feeding device is continuously feeding, and at this time the receiving reel is not operating, it is necessary for the receiving buffer roller (the same as the buffer roller 510) to collect the waste film tape from the feeding device and passing through the foaming station. At this time, the receiving buffer roller needs to continuously rise; therefore, the initial positions of the receiving buffer roller and the buffer roller 510 are different.

[0073] As Figure 37 , 39 , 40 and Figure 38 shown respectively represent the operation schematic diagrams of the four sets of receiving devices and feeding devices of this system. In Figure 38 , it represents the feeding and receiving devices installed at the bottom of the foaming production line. Compared with the feeding and receiving devices installed in the other three positions, the tensioning device 7 of the feeding device installed at the bottom is different from the tensioning devices 7 in the other three positions, that is, two additional tensioning rollers 21 are added, and the running direction of the film tape is also different. The receiving tensioning roller at this position is also slightly different from the feeding tensioning roller, and the waste film tape tensioning device 17 of the receiving device at this position is also slightly different from the waste film tape tensioning devices 17 in other positions.
