[0002] The processing of plastic products includes vacuum forming and compression molding. After the plastic is heated and softened, the molding mechanism will vacuum form or compression mold the plastic, and finally separate the molded product from the waste by cutting. Traditional plastic product processing equipment uses traction rollers to transport material sheets. When the plastic sheets are heated and softened, they will be stretched during the traction process, causing deformation, which will affect the product quality. In addition, regardless of heating, molding, or cutting, the mold is replaced according to the shape and size specifications of the processed product. However, the installation and disassembly of the molds of existing processing equipment are very cumbersome, the molds are large in size and heavy in weight, and loading and unloading the molds takes a lot of time and manpower.

DETAILED DESCRIPTION

[0021] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. Figure 1 The X-axis direction of the present invention is longitudinal, i.e., front-to-back direction; the Y-axis direction is transverse, i.e., left-right direction; and the Z-axis direction is vertical, i.e., up-down direction.

The above mechanisms correspond to the discharge station, heating station, molding station, cutting station, discharging station, and waste removal station, respectively. Users can also add punching stations, unloading stations, etc. according to processing requirements. The unloading mechanism includes an unloading shaft, and the plastic sheet coil is placed on the unloading shaft; the heating mechanism includes a heating component, and the heating component heats the plate 1; the molding mechanism includes a molding mold; the cutting mechanism includes a cutting mold; the material conveying mechanism passes through the heating mechanism, the molding mechanism and the cutting mechanism in sequence, and the material conveying mechanism includes a transmission chain and a clamping member installed on the transmission chain, and the transmission chain includes a left transmission chain and a right transmission chain that are symmetrical on the left and right; the discharging mechanism includes a manipulator and a conveyor belt; the unloading mechanism, the heating mechanism, the molding mechanism, the cutting mechanism, the material conveying mechanism, the discharging mechanism and the waste cleaning mechanism are all connected to the electrical controller.

[0022] The clamping parts of the present invention clamp the left and right sides of the material, and the transmission chain sends the material to the heating station, the molding station and the cutting station in sequence. Finally, the molded product is sent to the conveyor belt by the manipulator, and the waste is discharged by the waste removal mechanism, thus realizing automatic processing. The clamping parts clamp the left and right sides of the material, so that during the conveying process, the material will not be longitudinally stretched, ensuring stable material conveying, thereby improving product quality.

[0023] See attached Figure 3-6 The heating component also includes a mounting seat 7, a heating plate 1, a mounting plate 4, and a locking member 8 for locking the mounting plate and the mounting seat; the mounting seat is provided with a mounting groove 6; a column 5 is installed on the heating plate; the column is connected to the mounting plate 4, the mounting plate is horizontally inserted into the mounting groove 6, and the height of the mounting plate 4 is shorter than that of the mounting groove 6, and the mounting plate can enter and exit the mounting groove very smoothly, and the mounting plate can enter and exit the mounting groove together with the heating plate, so the mounting groove 6 is open, and the mounting plate can be supported by two inner support plates 9 at the lower end of the mounting seat. When installing the present invention, the mounting plate 4 is inserted into the mounting groove 6 of the mounting seat, and the mounting plate and the mounting seat are fixed and locked by the locking member 8. When disassembling, the locking member is loosened, and the mounting plate can be pulled out of the mounting groove. The disassembly and assembly of the heating plate is very convenient and quick. The locking member can be locked by bolts, and the bolts are threadedly connected with the heating plate and the mounting seat to lock and fix the two; or the bolts hold the heating plate against the inner wall of the mounting seat or the inner support plate of the mounting seat. In this embodiment, the mounting seat 7 and the mounting plate 4 are respectively provided with a mounting hole 1 27 and a mounting hole 2, and the mounting hole 1 is divided into a limit section and a positioning section, and the diameter of the limit section is smaller than the diameter of the positioning section; the locking member includes a bolt and a spring 1 25, and the bolt includes a head 24 and a screw rod, and the screw rod is divided into a main body 26, 28 and a threaded section 29, and the main body is connected with the head 24, and the threaded section passes through the mounting hole 1 27 and matches with the thread of the mounting hole 2, and the main body is further divided into a connecting section 26 matching the limit section of the mounting hole 1 and a guide section 28 matching the positioning section; the spring 1 25 is sleeved outside the screw rod and is arranged between the head 24 of the bolt and the mounting seat 7. The bolt goes deep into the mounting seat, and the threaded section 29 passes through the mounting hole 1 and is threadedly connected with the mounting plate 4. The bolt makes the mounting plate 4 close to the inner wall of the mounting seat 7. When the bolt is loosened, the elastic force of the spring 1 25 makes the bolt head away from the mounting seat, and the main body moves in the mounting hole 1 27. Because the outer diameter of the guide section of the main body is smaller than the limiting section of the mounting hole 1, the guide section of the main body is stuck in the mounting hole 1 27, and the threaded section of the bolt is completely separated from the mounting plate 4. At this time, the mounting plate is not restricted by the bolt and can be moved out of the mounting groove 6. The mounting plate is provided with a limiting block 3, and the mounting plate is inserted into the mounting groove 6 until the limiting plate contacts the mounting seat to determine the installation position and improve the installation efficiency.

[0024] When heating the material, single-sided heating or double-sided heating can be used. The single-sided heating only sets a single group of heating components, that is, the heating plate 1 is combined with the lower support plate, the material is placed on the lower support plate, and the heating plate moves down and presses with the lower support plate to heat the material; the double-sided heating uses two groups of upper and lower heating components, including an upper heating component 30 and a lower heating component 31, and the upper and lower heating plates are pressed to heat the upper and lower surfaces of the material at the same time. This embodiment is double-sided heating, and the heating components are provided with upper and lower groups, which are divided into upper heating components and lower heating components. For the convenience of distinction, the upper heating component is prefixed with "upper", and the lower heating component is prefixed with "lower", such as the heating plate of the upper heating component is the upper heating plate, and the heating plate of the lower heating component is the lower heating plate. In order to improve the heating effect and make the heating plate 1 close to the material, the upper heating plate adopts a floating design, and the upper mounting plate 4 is provided with an upper through hole, and the upper column 5 passes through the upper through hole and is connected with the upper nut 32. The outer diameter of the upper column is smaller than the upper through hole, and a spring 2 is provided between the upper mounting plate and the upper heating plate. The lower heating plate adopts a fixed design, and the lower column is fixedly connected to the mounting plate. When the upper and lower heating plates are pressed together, spring 2 is compressed, and the elastic force of spring 2 makes the heating plate always close to the material. When the material is thicker, spring 2 is compressed more severely, and the upper heating plate floats more relatively. When the material is heated and softened, it will become slightly thinner after softening. At this time, the elastic force of spring 2 will make the upper heating plate 1 move downward relatively, so that it is close to the surface of the material, transfer heat to the material, and improve the heating effect and heating efficiency. The upper heating component and the lower heating component are provided with at least two sets. The present invention adopts three sets of heating components, namely the first heating component 13, the second heating component 15 and the third heating component 17. Each set of heating components is arranged longitudinally on the frame 16 in sequence, and the temperature of the heating plate is gradually increased along the conveying direction. The heating plate temperature of the first heating component is the lowest, and the heating plate temperature of the third heating component is the highest. For thick plate materials, relatively high temperature and long heating time are required, which not only has low heating efficiency, but also directly uses high-temperature heating to affect product quality. The present invention divides heating into multiple stations and gradually increases the temperature, which shortens the heating time of each station and speeds up the heating efficiency. However, the total heating time is sufficient to soften the material, and the material is heated from a relatively low temperature to a relatively high temperature, so that the material is gradually softened and the softening effect is better.

[0025] In order to be suitable for processing different products and materials of different thicknesses, the longitudinal position and vertical position of the heating plate 1 can be adjusted. The mounting seat 7 is slidably arranged on the panel 12, and a vertically arranged first guide rail 11 is installed on the panel. The mounting seat is provided with a first slide 10 that slides with the guide rail. The mounting seat 7 is connected to a driving component that drives it to move up and down along the first guide rail 11. A slide is installed on the panel 12, and the slide is slidably arranged on the second guide rail 14, and the second guide rail is longitudinally installed on the frame 16. The mounting seat moves vertically on the first guide rail to adjust the vertical position of the heating plate, and the panel moves longitudinally on the second guide rail to adjust the longitudinal position of the heating plate, so as to be suitable for processing different products. In order to improve the accuracy of adjustment, fine adjustment is also provided; the mounting seat 7 is connected to a first screw 19, the first screw is threadedly connected to one end of a nut 18, the other end of the nut is threadedly connected to a second screw 20, the second screw is connected to a driving component, the two ends of the nut 18 are opposite threads, that is, one end of the nut is a forward thread, and the other end is a reverse thread. By rotating the nut, the first screw and the second screw can move toward or in the opposite direction, thereby realizing fine adjustment of the height of the heating plate. The driving component can use a cylinder to directly drive the mounting seat to be lifted and lowered along the first linear guide rail. In this embodiment, the driving component includes a power source 23, an output shaft 22 and a connecting rod 21. The output shaft is connected to the power source in a transmission manner. The power source can use a cylinder or a motor. The power source drives the output shaft to rotate forward or reverse. The connecting rod is connected to the output shaft. The second screw of the upper heating component and the second screw of the lower heating component are respectively hinged to the two ends of the connecting rod. When the output shaft rotates forward, the connecting rod drives the upper heating plate to move downward and the lower heating plate to move upward. Conversely, when the output shaft reverses, the connecting rod drives the upper heating plate to move up and reset, and the lower heating plate to move down and reset. That is, one power source simultaneously drives the heating plates of the upper and lower heating components to move toward or in the opposite direction, which saves costs and enables the upper and lower heating components to operate synchronously.

[0026] See attached Figure 7-13The molding die includes a male mold part 51, an upper mold part 52 and a lower mold part 53. The punch component includes a punch seat 60, a punch 61, a locking member 2 for locking the punch to the punch seat, and a positioning member. A linear guide 64 is installed at the bottom of the punch seat, and the linear guide is arranged horizontally; a slide groove 63 for the linear guide to move is provided at the top of the punch, and the linear guide has a protruding portion 62. Both ends of the opening of the slide groove have inner supporting plates 65. The linear guide 64 is aligned with the slide groove 63. After the punch is pushed in, the punch 61 is hooked on the linear guide 64, and the protruding portion 62 of the linear guide is placed in the slide groove 63. The protruding portion 62 of the linear guide supports the inner supporting plate 65, and also supports the punch 61; the height of the slide groove is higher than the protruding portion of the linear guide. Similarly, the punch can move in and out smoothly; the locking member 2 includes a bolt 54; the positioning member includes a positioning pin, which is not drawn in the figure. The positioning pin is installed on the punch seat, and the punch is provided with a corresponding positioning hole. When installing the punch, align the slide groove of the punch with the linear guide on the punch seat, then push the punch in, and the punch 61 is hooked on the linear guide 64, and finally connected with the punch by bolts, the bolts pull up the punch, and the positioning pins are inserted into the positioning holes to achieve accurate positioning of the punch installation. When disassembling, loosen the bolts, move the punch down and hang it on the linear guide, and pull the punch out of the punch seat. The positioning pins and positioning holes play a positioning role to ensure accurate installation position. In this embodiment, the locking member 2 can also adopt the structure of the locking member of the heating mechanism, that is, the punch seat 60 and the punch 61 are respectively provided with a mounting hole 1 57 and a mounting hole 2, the mounting hole 1 is divided into a limiting section and a positioning section, and the diameter of the limiting section is smaller than the diameter of the positioning section; the locking member 2 also includes a spring 2 55, the bolt includes a head 56 and a screw rod, the screw rod is divided into a main body 54, 58 and a threaded section 59, the main body is connected to the head 56, the threaded section 59 passes through the mounting hole 1 57 and is threadedly matched with the mounting hole 2, and the main body is further divided into a connecting section 54 matching the limiting section of the mounting hole 1 and a guide section 58 matching the positioning section; the spring 2 55 is sleeved outside the screw rod and is arranged between the head 56 of the bolt and the punch seat 60. The lower end of the bolt penetrates into the punch seat, and the threaded section 59 passes through the mounting hole 57 and is threadedly connected to the punch 61. The bolt makes the punch 61 close to the punch seat 60. When the bolt is loosened, the elastic force of the spring 55 moves the bolt upward, and the main body moves in the mounting hole 57. Because the outer diameter of the guide section of the main body is smaller than the limiting section of the mounting hole 1, the guide section of the main body is stuck in the mounting hole 57, and the threaded section of the bolt is completely separated from the punch 61. At this time, the punch is not restricted by the bolt and can be pulled out.

[0027] The upper mold component 52 includes an upper mold 68, an upper mold base 66, and a locking member 3 for locking the upper mold with the upper mold base. Flanges 70 are provided on both sides of the upper end of the upper mold; a support plate 71 for supporting the flange of the upper mold is provided at the bottom of the lower mold base, and there is an installation gap between the support plate and the bottom of the upper mold base, and the height of the installation gap is higher than the height of the upper mold; the locking member 3 includes a locking bolt 67. The upper mold of the present invention can also adopt a quick-release structure. When installing the upper mold, the two sides of the upper mold are inserted into the installation gap, and the support plate 71 supports the upper mold. Finally, the locking member 3 pulls the upper mold 68 upward to fix and lock the upper mold with the upper mold base. When disassembling, the locking member 3 is released, the upper mold is moved down and placed on the support plate, and then the upper mold is pulled out from the support plate. To ensure the accuracy of installation, a locating pin 69 is installed on the upper mold base, and a locating hole is correspondingly provided on the upper mold. When the upper mold is placed on the support plate 71, only by ensuring that the locating pin is aligned with the locating hole, the locking bolt moves the upper mold up and presses it with the upper mold base, and the locating pin is just inserted into the locating hole. If the upper mold is not in place, the locating pin and the locating hole are offset, then the locating pin will block the upper mold from moving up, so the locking bolt will pull the upper mold, and the upper mold and the upper mold base cannot be locked. The locking bolt can be directly connected to the upper die thread, or the locking bolt can be connected to the support plate thread, and the upper die can be moved up by pulling the support plate, see the attached figure. In this embodiment, according to the installation requirements, the lower end of the locking bolt is connected to the support plate thread, and a linear bearing 73 is installed on the upper die seat, and the linear bearing is vertically arranged. A guide column 72 matching the linear bearing is installed on the support plate, and the guide column is inserted into the linear bearing; the locking bolt pulls the support plate upward, reduces the installation gap between the support plate and the upper die seat, and locks the upper die and the upper die seat. The arrangement of the linear bearing and the guide column ensures the stability of the lifting and lowering of the support plate. The locking member three in the upper die component can also adopt the structure of the locking member two, and the locking member two in the male die component can also adopt the structure of the locking member three, and the structures of the two can be shared.

[0028] The lower die component 53 includes a die seat 74, a die 75 and four locking members for locking the die and the die seat. The die seat is provided with a guide rail 84, which is arranged transversely. The bottom of the die is provided with a guide groove that slides with the guide rail, and the guide rail guides the die. When installing the die, align the guide groove of the die with the guide rail 84 on the die seat, and push the die onto the die seat 74. At this time, the guide rail is inserted into the guide groove. Finally, the die and the die seat are fixed and locked by the four locking members. When disassembling, release the four locking members and pull the die out of the die seat. This makes disassembly and assembly very convenient and quick. The locking member 4 can be bolted, and the die and the die seat are locked and fixed by the bolts. The locking member 4 includes a locking block 76, and a groove 80 is provided on the upper side of the locking block, and the top of the groove is a convex tenon 82 of the locking block. The bottom of the die is provided with a mortise 83 for the convex tenon of the locking block to be inserted horizontally, and a convex strip 81 for supporting the convex tenon, and the convex strip is placed in the groove 80 of the locking block. The mortise 83 of the die is higher than the convex tenon 82 of the locking block, and the groove 80 of the locking block is higher than the convex strip 81 of the die, that is, the locking block 66 can move up and down relative to the die 75; a vertically arranged guide hole is provided on the die seat, and the lower end of the locking block is placed in the guide hole and moves up and down in the guide hole. The die is pushed onto the die seat 74, and the tenon head 82 of the locking block is inserted into the tenon groove 83 of the die. At this time, there is a gap between the tenon head 82 and the convex strip 81. After the die is in place, the locking block 76 moves down, and the tenon head 82 presses the convex strip of the die, and the die is fixed on the die seat. During disassembly, the locking block moves up, and there is a gap between the tenon head and the convex strip. The die can move laterally relative to the locking block, and then the die is pulled out from the die seat. Because the lower part of the die is connected to the power source that drives it to rise and fall, the locking block is arranged in the die seat. In order to facilitate the movement of the locking block, the locking member 74 also includes a locking bolt 79 and a spring 77 that pushes the locking block to move upward. One end of the locking bolt is a locking tongue 78. The locking tongue of the locking bolt is conical, that is, the surface of the locking tongue has a taper. The lower end of the locking block is provided with a locking hole that matches the locking bolt. The die seat is provided with a mounting hole that communicates with the guide hole. The mounting hole is arranged horizontally. The bolt 79 is threadedly connected to the mounting hole, and the locking tongue 78 passes through the mounting hole and is inserted into the locking hole. The other end of the locking bolt is placed outside the die seat 74, and a knob can be added to facilitate the rotation of the locking bolt; the spring 77 is arranged between the locking block 76 and the die seat 74. In order to facilitate the installation of the spring, a spring mounting hole is opened at the bottom of the locking block. The spring is placed in the spring mounting hole, the upper end of the spring contacts the locking block, and the lower end contacts the die seat. The elastic force of the spring pushes the locking block 76 to move upward.When the die is in place, the locking bolt is rotated to make the locking tongue 78 penetrate into the locking hole, and the conical surface of the locking tongue drives the locking block 76 to move down, and the die is locked on the die seat. When the locking bolt is rotated in the opposite direction, the locking tongue 78 partially withdraws, and the elastic force of the spring 77 drives the locking block 76 to move up, and the die is in a free state. In order to make the structure more streamlined, the guide groove of the die is a tenon groove 83, and the upper end of the guide rail 84 and the locking block are matched with the guide groove 83, that is, the guide groove of the die is also used as the tenon groove, and the guide groove and the tenon groove are integrated into one. The shape of the guide groove is the same as the tenon groove, and the convex tenon head 82 of the locking block is inserted into the guide groove 83 of the die, and there is a gap between the convex tenon head 82 and the convex strip 81. When the locking block moves down, the die is fixed, otherwise the die can move, so there is no need to open an additional tenon groove on the die, and the tenon groove processing is omitted. The die seat 74 is provided with a limit block 77, on which a fine-tuning top plate 76 is installed. The top plate is arranged horizontally and is threadedly connected to the limit block. The limit block 77 limits the horizontal position of the die on the die seat. The die is pushed onto the die seat 74 until it contacts the limit block 77. The position of the limit block limits the horizontal position of the die on the die seat; the top plate fine-tunes the horizontal position of the die. If there is a precision problem in the mold processing, if the horizontal position of the mold needs to be moved to the right, the top plate 76 is rotated, the top plate extends out, the die contacts the top plate, and the top plate controls the horizontal position of the die. In this way, the horizontal position of the die is accurately determined, and the molding quality and product quality are improved.

[0030] Also, in order to adapt to the processing of products of different specifications, the longitudinal positions of the forming mechanism and the cutting mechanism on the frame can be adjusted. A longitudinal guide rail and a screw mechanism are arranged on the frame. The screw mechanism drives the forming mechanism or the cutting mechanism to move along the longitudinal guide rail on the frame, thereby realizing the adjustment of the longitudinal position.

[0031] See attached Figure 17-19 The material conveying mechanism also includes a transmission wheel 113, which is arranged horizontally; the transmission chain 115 is horizontally wound around the transmission wheel, and the transmission chain and the transmission wheel are arranged horizontally, which makes the use state more intuitive and convenient for disassembly and assembly of components; the clamping member 112 includes a mounting plate 125, an upper clamping plate 117 that moves up and down, a lower clamping plate 118, a guide plate 119, and a spring 120 that enables the clamping head to engage with the lower clamping plate, the mounting plate 125 is installed on the transmission chain 115, and the transmission chain The number of clamping parts is set according to demand, and the clamping parts should be evenly distributed. One end of the upper clamping plate 117 is provided with a clamping head 121, and the other end is connected with a linkage rod 123. The lower clamping plate 118 is installed on the mounting plate 125, and the lower clamping plate is provided with a mounting hole 124. The guide plate 119 is installed on the mounting plate and arranged below the lower clamping plate. The guide plate is also provided with a mounting hole 126. The mounting plate, the lower clamping plate, and the guide plate can be designed as an integral part or as a separate part. See attached Figure 4In this embodiment, the lower clamping plate and the guide plate are designed as one body, the mounting plate 125 is L-shaped, the horizontal panel is connected to the transmission chain, the vertical panel is connected to the connecting plate of the upper clamping plate and the guide plate, the linkage rod 123 passes through the mounting hole 124 and the mounting hole 2 126 in sequence, in this embodiment, the spring sleeve is arranged outside the linkage rod, the upper end of the spring contacts the lower clamping plate 118, and the lower end of the spring is connected to the linkage rod 123, the elastic force of the spring presses the lower clamping plate, and the upward movement of the linkage rod needs to overcome the elastic force of the spring, at this time A gap is generated between the clamping head 121 and the lower clamping plate 118, the clamping piece opens, and the plastic sheet can enter between the two. When the force pushing the connecting rod 123 to move upward disappears, the elastic force of the spring 120 drives the connecting rod to move downward and reset, and the clamping head 121 engages with the lower clamping plate 118 to clamp the plastic sheet; the clamping pieces on the left and right transmission chains clamp the two sides of the plastic sheet, and the transmission wheel 113 rotates to drive the transmission chain 115 to deliver the clamping pieces 112 on the transmission chain and the plastic sheet clamped by the clamping pieces to different workstations. An opening and clamping station 111 is provided on the conveying path of the conveying mechanism. The opening and clamping station is preferably arranged at both ends of the conveying path, between the discharge mechanism and the heating mechanism and between the cutting mechanism and the discharge mechanism. When the plastic sheet enters from the beginning, the clamping member 111 is opened, and after clamping, it is sent to the heating station, the molding station, and the cutting station. After the processing is completed, the clamping member is finally opened again, and the plastic sheet or waste is sent out. The unclamping station 111 is provided with a plane cam 114, and the cam surface 116 of the plane cam is horizontally arranged. The cam surface 116 of the plane cam gradually rises along the conveying direction. The plane cam is arranged below the clamp 112. At the unclamping station, the bottom of the connecting rod 123 contacts the cam surface 116 of the plane cam and the gradually rising cam surface pushes the connecting rod 123 to move upward. When the connecting rod moves upward, a gap is generated between the clamping head and the lower clamping plate. When the clamping part leaves the unclamping station, that is, the lower end of the connecting rod is not in contact with the plane cam, so that the lower part of the connecting rod is suspended, the elastic force of the spring 120 causes it to move down and reset, and the clamping head 121 engages with the lower clamping plate 118, thereby realizing automatic unclamping and clamping operations. The connecting rod 118 is tilted or bent, and the connecting rod forms an angle less than 90 degrees with the upper clamping plate.

When the planar cam 114 supports the connecting rod to move it upward, the connecting rod does not move vertically upward, but moves obliquely backward along the angle defined by the mounting holes 1 and 2 to expand the opening. In this way, even if the upward stroke is small, the opening can be opened larger, and the plastic sheet can be easier to enter. In order to make the movement of the connecting rod stable, the widths of the mounting holes 1 and 2 match the width of the connecting rod to play a guiding role.The clamping end of the upper clamp 121 is bent downward and is in the shape of sharp teeth. The upper surface of the lower clamp plate is provided with a bite groove 122. The sharp tooth-shaped clamping end can pass through the plastic sheet and be inserted into the bite groove, so that the clamping is more secure.

The lifting component and the moving component can adopt a cylinder or a screw mechanism, etc. In order to ensure the stable movement of the manipulator, a vertical guide rail 48 and a transverse guide rail 47 are arranged on the frame, so that the manipulator can move up and down along the vertical guide rail and move left and right along the transverse guide rail. In this way, the manipulator 42 moves vertically and horizontally to the cutting station to absorb the finished product 43 or grab the finished product and then moves to the discharging station, places the finished product on the conveyor belt 44, and the conveyor belt sends the finished product out. The waste clearing mechanism includes a transversely arranged cutter 45 and a waste conveyor belt 46. The cutter is arranged in front of the clamping station, and the waste conveyor belt is arranged side by side with the conveyor belt 44. After the material is formed, it is cut by the cutting mechanism to separate the finished product from the waste. The manipulator sends the finished product to the discharging station, and the material conveying mechanism still conveys the waste forward. When the waste reaches the waste clearing station, the cutter cuts the continuous waste into sheet-like waste. The sheet-like waste is placed on the waste conveyor belt and sent out by the waste conveyor belt 46 for unified collection.
