Abstract
Description
Technical Field
[0001] This utility model relates to a die-cutting machine, and particularly to its separation mechanism. Background Technology
[0002] After die-cutting, rolled materials (such as paper or film) need to be separated from waste (i.e., scrap edges) and the finished products are collected. Generally, after die-cutting, rolled materials form rows of side-by-side finished units. These units are separated by scrap (i.e., scrap edges) both side-by-side and front-to-back. Removing each finished unit leaves empty spaces (at this point, the rolled material is considered waste). For relatively short finished units (i.e., the dimension along the direction of travel of the rolled material), separating the finished unit from the waste is relatively difficult, easily resulting in incomplete separation and the finished unit being collected along with the waste, causing losses. Additionally, for materials with relatively low basis weight, which are relatively soft, separating the finished unit from the waste is also relatively difficult. The finished unit may not be completely separated from the rolled material (e.g., the front of the finished unit may be separated from the waste, but the back may not), and instead, it is collected along with the waste. In addition, there may still be burrs or other connections between the finished product unit and the waste material after die-cutting, which also hinders their separation. Utility Model Content
[0003] In view of the technical problems existing in the background art, the present invention aims to provide a finished product waste separation mechanism for a relatively stable die-cutting machine.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a finished product waste separation mechanism for a die-cutting machine, comprising a discharge conveyor belt, a separation pressure roller, a separation plate, and a waste traction device, characterized in that: the discharge conveyor belt is wound around a drive shaft, the drive shaft is connected to a feeding drive device, the separation pressure roller is pressed and disposed above the discharge conveyor belt, the separation plate is located above the discharge conveyor belt, the separation plate is disposed on the input side of the separation pressure roller, the leading edge of the separation plate is a separation support edge, the separation support edge is connected to the input side behind the separation pressure roller, and the waste traction device includes a separation feed roller, which is connected and disposed above the separation plate.
[0005] The following optimizations or supplementary explanations can be made to the above technical solutions.
[0006] For example, the rear side of the discharge conveyor belt is the input side and connects to the discharge end of the die-cutting device, the front side of the discharge conveyor belt is the output side, and the separating pressure roller is set as a passive pressure roller.
[0007] In addition, a support shaft can be provided on the inner side of the discharge conveyor belt, and the support shaft is located below the separating pressure wheel; the drive shaft acts as the support shaft, the feeding drive device includes a feeding drive motor, the discharge conveyor belt is also equipped with a passive shaft, the drive shaft is located in front of the passive shaft, the discharge conveyor belt is wound around the drive shaft and the passive shaft, and the feeding area of the discharge conveyor belt is between the passive shaft and the drive shaft; the inner side of the discharge conveyor belt is also equipped with a pad.
[0008] For example, the separating pressure roller is mounted on the support shaft, and the separating pressure rollers are installed side by side on the support shaft. The two ends of the support shaft are respectively mounted on the lifting and shifting seat. A bearing is provided between the support shaft and the lifting and shifting seat, and the lifting and shifting seat is connected to a lifting and shifting drive component.
[0009] For example, the waste traction device also includes a traction drive motor, and the separating feed roller is equipped with a split-and-joint switching pressure roller. The separating feed roller is connected to the traction drive motor and is located on the rear side of the separating support edge.
[0010] The separation support edge has a smooth support surface. For example, the front end of the separation plate curves upwards and backwards to form the separation support edge.
[0011] In addition, the separation plate also has a material inlet section, which is located on the lower side of the separation plate; the material inlet section is set as a sloping plane or a curved surface with a lower front and higher back.
[0012] For example, the separation plate is an inclined plate, the lower side of the inclined plate is set as the material inlet, the inclined plate is set with the front lower and the back higher, and the front end of the inclined plate is set as the separation support edge.
[0013] Furthermore, the separating plate is mounted on a movable shifting seat, which is positioned on a linear guide rail. The linear guide rail is angled, with the front lower than the rear. The movable shifting seat is connected to a forward and backward shifting drive component that moves it along the linear guide rail. The relative position of the separating plate on the movable shifting seat is adjustable.
[0014] The beneficial effects of this invention are that the finished product waste separation mechanism of the die-cutting machine, with its discharge conveyor belt, separating pressure roller, separating plate, and waste traction device working together, improves the success rate and stability of separating finished product units from waste after die-cutting of continuous roll material. It can be used to separate finished product units that are relatively short, lightweight, or have rough edges from continuous roll material. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0029] Referring to the accompanying drawings, in this embodiment, the finished product waste separation mechanism of the die-cutting machine includes a discharge conveyor belt 1, a separation pressing wheel 2, a separation plate 3, and a waste traction device 4.
[0030] The discharge conveyor belt 1 is wound around the drive shaft 5, which is connected to the feeding drive device 50. The feeding drive device 50 drives the drive shaft 5 to rotate, and the drive shaft 5 drives the discharge conveyor belt 1 to run. The discharge conveyor belt 1 supports and transports the die-cut material (continuous roll material, including finished product units and waste material), preventing the finished product units formed by die-cutting from accidentally falling off or detaching, which would affect normal collection.
[0031] Among them, the separating pressing roller 2 is positioned above the discharge conveyor belt 1. The separating pressing roller 2 can press on the discharge conveyor belt 1 to press and convey the finished product units (on the continuous roll material) on the discharge conveyor belt 1. It can also help to smoothly separate the die-cut finished product units from the waste material (i.e. waste edge) on the continuous roll material.
[0032] The separation plate 3 is located above the discharge conveyor belt 1. The separation plate 3 is set on the input side (i.e. the rear side) of the separation pressure roller 2, and the finished product unit is input into the separation pressure roller 2 from the rear side. The leading edge of the separation plate 3 is the separation support edge 30, which is connected to the input side behind the separation pressure roller 2. The separation support edge 30 of the separation plate 3 is used to support the continuous rolled material so as to facilitate the separation of the finished product unit from the waste material.
[0033] The waste traction device 4 includes a separating feed roller 40, which is used to pull the waste output on the continuous rolled material, thereby separating the waste on the continuous rolled material from the finished product unit. The separating feed roller 40 is connected and arranged above the separating plate 3. The separating feed roller 40 is used to feed the waste of the continuous rolled material, and the separating feed roller 40 helps to separate the waste from the finished product unit.
[0034] Its working principle is as follows: After being die-cut, the continuous rolled material is fed into the discharge conveyor belt 1, which is connected to the discharge conveyor belt 1 to transport the die-cut continuous rolled material (including finished products and waste) out; the discharge conveyor belt 1 supports the die-cut continuous rolled material for transport; the waste material (downstream) of the continuous rolled material is pulled by the waste traction device 4, which can work with the discharge conveyor belt 1 to continuously pull, transport and output the continuous rolled material; when the die-cut continuous rolled material passes through the separation plate 3, the waste material can be guided upward by the separation feed roller 40, and the finished unit of the continuous rolled material can continue to move forward and be pressed and pressed on the discharge conveyor belt 1 by the separation pressure roller 2, so as to avoid the finished unit lifting up and affecting the separation or to avoid the problem that although the front part of the finished unit is separated from the waste, the rear part of the finished unit is still not separated and is carried away by the waste. The finished unit of the continuous rolled material and the waste (the waste is in a continuous state) are supported by the separation support edge 30 at the front of the separation plate 3, and are separated from each other at this point (separation support edge 30).
[0035] In the finished product waste separation mechanism of this die-cutting machine, the discharge conveyor belt 1, the separating pressure roller 2, the separating plate 3, and the waste traction device 4 work together to improve the success rate and stability of separating finished product units from waste after die-cutting of continuous roll material. It can be used to separate finished product units that are shorter in size, relatively lighter in weight, and have rough edges from continuous roll material.
[0036] Based on the above embodiments, the following optimizations or further explanations can be made.
[0037] For example, the rear side of the discharge conveyor belt 1 is the input side and connects to the discharge end of the die-cutting device, meaning the discharge conveyor belt 1 is used to connect the (die-cut) roll material output by the die-cutting device. The front side of the discharge conveyor belt 1 is the output side, which can connect to equipment for sorting finished product units. The separating pressure roller 2 is a passive pressure roller, meaning it rotates passively, driven by the structure below (such as the discharge conveyor belt 1) to press and transport the finished product units.
[0038] Furthermore, it can be optimized by providing a supporting shaft on the inner side of the discharge conveyor belt 1. The supporting shaft is positioned below the separating pressure roller 2. The supporting shaft, in conjunction with the discharge conveyor belt 1, supports the separating pressure roller 2 in conveying the finished product unit. This results in relatively stable operation, as the separating pressure roller 2 can stably cooperate with the discharge conveyor belt 1 to press down the finished product unit and ensure smooth transport. Alternatively, the drive shaft 5 can be used as the supporting shaft, resulting in a more compact structure.
[0039] The feeding drive device 50 includes a feeding drive motor (such as a servo motor). Additionally, the discharge conveyor belt 1 is equipped with a passive rotating shaft 7, with a drive shaft 5 located in front of the passive rotating shaft 7. The discharge conveyor belt 1 is wound around the drive shaft 5 and the passive rotating shaft 7, and runs on them. The area between the passive rotating shaft 7 and the drive shaft 5 is the feeding zone of the discharge conveyor belt 1, typically configured as a translational feeding path. Furthermore, a pad 8 can be placed inside the discharge conveyor belt 1 to support it and increase its stability; the pad 8 can be positioned below the separation plate 3 corresponding to the feeding zone.
[0040] The separating pressure roller 2 can be mounted on the support shaft 20. Multiple separating pressure rollers 2 are installed side-by-side on the support shaft 20, corresponding to multiple finished product units on the continuously wound material, resulting in relatively good separation. Both ends of the support shaft 20 are respectively mounted on the lifting and shifting seat 21. The separating pressure roller 2 and the support shaft 20 can rise and fall together with the lifting and shifting seat 21 to switch positions. The descending pressure roller is in working condition for separating finished product units from waste material. The gap (or pressure) between the descending separating pressure roller 2 and the discharge conveyor belt 1 can even be adjusted to better match finished product units of different thicknesses. A bearing can be provided between the support shaft 20 and the lifting and shifting seat 21. The separating pressure roller 2 can be fixedly mounted on the support shaft 20, and the lifting and shifting seat 21 supports the support shaft 20 and the separating pressure roller 2 for rotation. The lifting and shifting seat 21 can be configured to rise and fall on the lifting groove or rail of the frame. The lifting and shifting seat 21 is connected to a lifting and shifting drive component 22 (such as a cylinder). For example, when the lifting and shifting drive component 22 is a cylinder, its piston rod is connected to the lifting and shifting seat 21. In order to adjust the height of the lifting and shifting seat 21 after it is lowered, the connection between the lifting and shifting seat 21 and the piston rod can be adjusted up and down (such as by using upper and lower nuts to clamp it). Of course, the lifting and shifting drive component 22 (such as including a servo motor) can also use a lead screw and nut mechanism to drive the lifting and shifting seat 21 to lift and adjust its position.
[0041] For example, the waste traction device 4 also includes a traction drive motor 41 (such as a servo motor), and the separating feed roller 40 is equipped with a split-and-joint switching pressure roller 42 (which can be driven by a cylinder for split-and-joint switching). The pressure roller 42 works to press the waste onto the separating feed roller 40 to hold it in place. The separation of the pressure roller 42 and the separating feed roller 40 facilitates the feeding operation. The separating feed roller 40 is connected to the traction drive motor 41, which directly drives the separating feed roller 40 to rotate. The separating feed roller 40 actively pulls the waste out, ensuring that the separating feed roller 40 can smoothly and stably pull the waste. The separating feed roller 40 is located behind the separating support edge 30, at an angle to the rear and above, which can better guide the separation of waste from the finished product unit. Typically, the waste traction device 4 matches (or keeps consistent with) the feed speed of the discharge conveyor belt 1 for the waste traction in the continuous roll material.
[0042] Among them, the separation support edge 30 has a smooth support surface, which makes it less likely for the waste material (such as its waste) to break when it turns and separates from the finished product unit. For example, the front end of the separation plate 3 is curved upward and backward to form the separation support edge 30. In this structure, the separation plate 3 can be directly formed by bending metal plate, which is more convenient for processing and manufacturing.
[0043] The separating plate 3 also has a material inlet section 31, which is located on the lower side of the separating plate 3. The material inlet section 31 on the separating plate 3 can smoothly guide the continuous rolled material (including the die-cut finished units and waste materials on it) from the discharge conveyor belt 1 below. The continuous rolled material is smoothly separated by the separating support edge 30. During the die-cutting process, the finished units may separate and curl up on the continuous rolled material. In this case, the material inlet section 31 will smoothly guide the continuous rolled material to avoid affecting the normal separation. The material inlet section 31 is set as a sloping plane or curved surface with a lower front and higher back. Generally, the separating plate 3 is a sloping plate. The lower side of the sloping plate can be directly set as the material inlet section 31 (such as a sloping plane). The sloping plate is set as a sloping plane with a lower front and higher back. The front end of the sloping plate is set as the separating support edge 30 (which can be bent into shape).
[0044] In addition, the separating plate 3 is installed on the movable shifting seat 32, which is configured on the linear guide rail 33 and can move stably along the linear guide rail 33. The movable shifting seat 32 is driven by a front and rear shifting drive component 34 that moves it along the linear guide rail 33. The front and rear shifting drive component 34 (such as including a motor or cylinder) drives the movable shifting seat 32 to move back and forth on the linear guide rail 33 to switch positions. It moves forward closer to the separating pressure roller 2 (to facilitate the smooth separation of finished product units and waste materials) and backward away from the separating pressure roller 2 (to facilitate the pre-winding of continuous roll material, with a larger operating space and greater convenience). There are many ways to drive the front and rear shifting drive component 34 (such as a cylinder). In the figure, a rotating block 36 with a sliding groove 38 is used to connect with a pin 37 on the movable shifting seat 32. Of course, a direct push method can also be used; or a motor can be used to drive it through a lead screw and nut mechanism.
[0045] Furthermore, the separation plate 3 is installed on the movable switching seat 32 with its relative position adjustable. For example, an elongated hole 35 is provided on the separation plate 3, which is connected to the mounting hole of the movable switching seat 32 by fasteners (such as screws). When the movable switching seat 32 moves forward to its position, the relative position (near or far) of the leading edge of the separation plate 3 (i.e., the separation support edge 30) and the separation pressing wheel 2 is different, so that it can be adjusted to ensure that the finished product unit and the waste are separated smoothly. Among them, the linear guide rail 33 can be set at an angle with the front lower and the back higher for better relative effect, better adjustment effect, and easier adaptation to the separation mechanism. There is a rearward open mating space between the discharge conveyor belt 1 and the upper separation pressing wheel 2, and the leading edge of the separation plate 3 is adjusted to the front and rear positions of this mating space.
