Description

Technical Field

[0001] This utility model relates to a cardboard processing machinery, specifically a cardboard slotting machine for slotting cardboard. Background Technology

[0002] Generally, paper packaging containers such as electronic packaging boxes and wine boxes are made by folding cardboard with V-grooves along the V-grooves. A cardboard slotting machine is a device used to slot cardboard. A typical cardboard slotting machine includes a cardboard feeding mechanism, a cardboard conveying mechanism, and a cardboard slotting mechanism. The cardboard feeding mechanism includes a stacking platform and a feeder. The cardboard conveying mechanism includes a guide conveyor belt. The cardboard slotting mechanism includes a slotting knife, slotting rollers, a belt, and multiple tension rollers. The belt is wound around the tension rollers, and under the action of the tension rollers, part of the belt is pressed against the slotting rollers. The cardboard on the stacking platform is fed sheet by sheet by the feeder onto the guide conveyor belt of the cardboard conveying mechanism. A guide feeding and correction mechanism is also installed above the guide conveyor belt. The paper feeding and correction mechanism includes a side plate, a paper support plate, and a correction roller. The paper support plate is connected to the side plate, the conveyor surface of the correction conveyor belt is above the paper support plate, and the correction roller is above the correction conveyor belt. After the cardboard arrives on the correction conveyor belt, it is pressed onto the belt by the correction roller. The paper support plate supports the correction conveyor belt (to prevent the correction roller from pressing the belt downwards and deforming it, thus affecting the correction effect). With the cooperation of the correction roller and the correction conveyor belt, the cardboard moves forward against the side plate, achieving correction conveying. Through the correction of the paper feeding and correction mechanism, the cardboard enters between the belt and the slotting roller against the side plate. In this way, the cardboard bends and adheres to the slotting roller under the action of the belt. The slotting roller rotates under the drive of the power source, causing the cardboard and the belt to rotate together. The slotting knife is located on one side of the slotting roller. As the cardboard moves, the slotting knife cuts grooves in the cardboard. Currently, the paper feeders of existing cardboard slotting machines are fixedly installed on the crossbeam and located in the middle of the crossbeam. When different sizes and specifications of cardboard need to be processed, the position of the paper feeding correction mechanism can only be adjusted so that the cardboard fed by the paper feeder can always be corrected by the paper feeding correction mechanism.

[0003] To accommodate different sizes of cardboard, the equipment is equipped with multiple narrow conveyor belts to ensure the stability of cardboard transport. One of these narrow conveyor belts (also called the alignment conveyor belt) is positioned above the paper support plate. When the position of the paper feeding alignment mechanism needs to be adjusted, the position of the alignment conveyor belt must also be moved first. Since the alignment conveyor belt is under tension, moving it is very inconvenient. In addition, when changing sizes, directly moving the paper feeding alignment mechanism can cause interference between the conveyor belts. In this case, the paper feeding alignment mechanism needs to be removed and moved across the existing conveyor belt to another conveyor belt, so that the paper support plate is positioned below the other conveyor belt to avoid interference between the conveyor belts. However, the bulky paper feeding alignment mechanism increases the workload of disassembly and is located at a relatively high position, making disassembly and assembly very inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model innovatively provides a feeder-adjustable cardboard slotting machine that can meet the needs of cardboard feeding and correction of different specifications without adjusting the paper feeding and correction mechanism. This feeder-adjustable cardboard slotting machine includes a cardboard feeding mechanism, a cardboard conveying mechanism, and a feeding and correction mechanism. The cardboard feeding mechanism is located at the inlet end of the cardboard conveying mechanism and includes a feeding bracket, a stacking platform, and a feeding feeder. The stacking platform is mounted on the feeding bracket, and the feeding feeder is located above the stacking platform. The cardboard conveying mechanism includes a conveying bracket and a correction conveyor belt. The feeding and correction mechanism includes a side plate, a paper support plate, and a correction pressure roller. The paper support plate is located on one side of the side plate, the conveying surface of the correction conveyor belt is located above the paper support plate, and the correction pressure roller is located above the correction conveyor belt. The key feature is that the feeding bracket is equipped with a left-right oriented guide rail, and a slide is provided on the guide rail. The feeding feeder is mounted on the slide.

[0005] The slide is equipped with a clamp, which can clamp onto the guide rail.

[0006] A connecting seat is installed on the slide block, and a mounting rod that can move back and forth is provided on the connecting seat. The paper feeder is installed on the mounting rod, and a fixing bolt is threadedly connected to the connecting seat. The fixing bolt can act on the mounting rod.

[0007] The feeding bracket is equipped with a baffle plate, a feeding pressure roller, and a feeding roller. The baffle plate is mounted on a connecting shaft, and a connecting shaft seat is mounted on the feeding bracket. The connecting shaft is rotatably mounted on the connecting shaft seat. One end of the connecting shaft is connected to one end of a connecting member, and the other end of the connecting member is hinged to one end of a connecting rod. The other end of the connecting rod is hinged to one end of a swing arm, and the other end of the swing arm is connected to a pressure roller shaft. The pressure roller shaft is rotatably mounted on the feeding bracket, and the feeding pressure roller is mounted on the pressure roller shaft. The swing arm is connected to a power source that drives the swing arm to swing along the axis of the pressure roller shaft. When the baffle plate is upright, the feeding pressure roller presses down and cooperates with the feeding roller to feed paper. When the baffle plate swings forward, the feeding pressure roller lifts up.

[0008] The feeding bracket is equipped with a rotatable cam, which is connected to the power source of the swing arm. A force-receiving wheel is connected to the swing arm. The cam can act on the force-receiving wheel and make the swing arm swing in one direction. A return spring is connected between the feeding bracket and the swing arm to make the swing arm swing in the opposite direction.

[0009] The paper stacking platform is vertically mounted on the feeding bracket, and the paper stacking platform is connected to the lifting power source that drives the paper stacking platform to move up and down.

[0010] The feeding and correction mechanism includes a paper feed guide plate, a correction pressure roller mounted on the paper feed guide plate, a paper feed guide plate mounted on a side plate, a side plate mounted on a conveying bracket, and the side plate located on one side of the correction pressure roller.

[0011] The paperboard conveying mechanism has a paperboard slotting mechanism at its discharge end. The paperboard slotting mechanism includes a slotting knife, a slotting roller, a paper pressing belt, and multiple tension rollers. The paper pressing belt is wound around the multiple tension rollers and is pressed onto the slotting roller by the action of the multiple tension rollers. The slotting knife is located on one side of the slotting roller.

[0012] According to the adjustable feeder cardboard slotting machine provided by this utility model, only the position of the paper feeder needs to be adjusted to meet the deviation correction and conveying requirements of cardboard of different specifications, which greatly reduces the difficulty of adjustment.

[0019] Figure 7 This is a cross-sectional view of the cardboard slotting mechanism. Detailed Implementation

[0020] like Figure 1 As shown, this feeder adjustable cardboard slotting machine includes a cardboard feeding mechanism 1, a cardboard conveying mechanism 2, and a board feeding and correction mechanism 3. The cardboard feeding mechanism 1 is used to provide cardboard; the cardboard conveying mechanism 2 is used to convey the cardboard sheets forward one by one; and the board feeding and correction mechanism 3 corrects the position of the cardboard during the conveying process, moves it forward along the edge, and thus enters the cardboard slotting mechanism 4 for slotting.

[0021] like Figure 1 As shown, the cardboard feeding mechanism 1 is located at the feed end of the cardboard conveying mechanism 2, as follows: Figure 2 As shown, the cardboard feeding mechanism 1 includes a feeding bracket 10, a stacking platform 11, and a paper feeder (the paper feeder is prior art and is not shown in the figure). The stacking platform 11 is mounted on the feeding bracket 10, and the paper feeder is located above the stacking platform 11. During operation, cardboard is stacked on the stacking platform 11, and the paper feeder picks up sheets of cardboard one by one and sends them to the cardboard conveying mechanism 2.

[0022] like Figure 1 As shown, the cardboard conveying mechanism 2 includes a conveying support 20 and a guiding conveyor belt 21, as follows: Figure 6 As shown, the feeding and correction mechanism 3 includes a side plate 32, a paper support plate 33, and a correction roller 31. The paper support plate 33 is located on one side of the side plate 32 (it can be connected to the side plate 32, for example, connected to the side or lower end of the side plate 32, or it can be directly connected to the conveyor support 20 without being connected to the side plate 32). The conveying surface of the correction conveyor belt 21 is located above the paper support plate 33, and the correction roller 31 is located above the correction conveyor belt 21. Figure 2 and Figure 3As shown, a left-right oriented guide rail 12 is installed on the feeding bracket 10, and a slide 13 is provided on the guide rail 12, while the paper feeder is installed on the slide 13. After the cardboard is fed to the cardboard conveying mechanism 2, the cardboard comes to the top of the correction conveyor belt 21. As the cardboard moves forward, the correction pressure roller 31 presses on the cardboard. Since the angle between the axis of the correction pressure roller 31 and the side plate 32 is less than 90° (which is prior art and can be referred to the patent with announcement number CN202967637U), the correction pressure roller 31 and the correction conveyor belt 21 cooperate to give the cardboard an oblique thrust (the resultant force in the forward direction and the side direction). This thrust pushes the cardboard to move forward and also to the side plate 32. In this way, under the guidance of the side plate 32, the side of the cardboard moves forward with the side surface of the side plate 32 as the reference, so that the position of the cardboard can be corrected (also known as correction). Finally, it enters the cardboard slotting mechanism 4 to achieve precise slotting. When different sizes of cardboard need to be processed, such as when the cardboard size becomes smaller, first adjust the position of the cardboard stack on the stacking platform 11 so that the cardboard stack is as close as possible to the side plate 32 of the feeding and correction mechanism 3. Then move the paper feeder on the guide rail 12 so that the paper feeder corresponds to the position of the cardboard stack. When the paper feeder is working, it can send the small-sized cardboard to the cardboard conveying mechanism 2 and close to the feeding and correction mechanism 3. In this way, the feeding and correction mechanism 3 can correct the small-sized cardboard. The feeding and correction mechanism 3 does not need to be adjusted, thus avoiding a lot of disassembly and assembly troubles.

[0023] Additionally, in order to lock the slide 13, such as Figure 2 and Figure 3 As shown, a clamp 14 is provided on the slide 13, which can clamp onto the guide rail 12. Of course, the slide 13 can also be locked onto the guide rail by bolts or locking blocks.

[0024] To adjust the forward and backward position of the paper feeder to meet the feeding requirements of different sizes of paperboard, such as... Figure 3 As shown, a connecting seat 15 is installed on the slide 13, and a mounting rod 16 that can move back and forth is provided on the connecting seat 15. The paper feeder is installed on the mounting rod 16. A fixing bolt is threaded onto the connecting seat 16, and the fixing bolt can act on the mounting rod 16. When it is necessary to adjust the back and forth position of the paper feeder, move the mounting rod 16 to the back and forth position on the connecting seat 16. After determining the position, tighten the fixing bolt. This completes the adjustment of the back and forth position of the paper feeder.

[0025] The paper feeder only picks up the cardboard and moves it forward a certain distance (without fully delivering the cardboard onto the cardboard conveyor 2). To ensure the cardboard is fully transferred to the cardboard conveyor 2, as follows... Figure 4As shown, a baffle plate 17, a feeding pressure roller 18, and a feeding roller 19 (driven by a power source to rotate continuously) are installed on the feeding bracket 10. The baffle plate 17 is mounted on a connecting shaft 171. A connecting shaft seat 170 is mounted on the feeding bracket 10. The connecting shaft 171 is rotatably mounted on the connecting shaft seat 170. One end of the connecting shaft 171 is connected to one end of a connecting member 172. The other end of the connecting member 172 is hinged to one end of a connecting rod 182. The other end of the connecting rod 182 is hinged to one end of a swing arm 181. The other end of the swing arm 181... One end is connected to the pressure roller shaft 180, which is rotatably mounted on the feeding bracket 10. The feeding pressure roller 18 is mounted on the pressure roller shaft 180. The swing arm 181 is connected to a power source that drives the swing arm 181 to swing along the axis of the pressure roller shaft 180. Driven by the power source, the swing arm 181 rotates, which in turn drives the pressure roller shaft 180 to rotate. This rotation, in turn, drives the connecting shaft 171 to rotate via the connecting rod 182 and the connecting piece 172. Thus, the feeding pressure roller 18 on the pressure roller shaft 180 and the baffle plate 17 on the connecting shaft 171 move synchronously. Figure 5 As shown, when the baffle plate 17 swings forward ( Figure 5 In the left-hand position), the feeding roller 18 is raised. In this position, when the paper feeder picks up the cardboard and moves it forward, it passes over the baffle plate 17 and enters the space between the feeding roller 18 and the feeding roller 19; Figure 5 As shown, when the front end of the cardboard comes between the feeding pressure roller 18 and the feeding roller 19, the baffle plate 17 stands upright. Figure 5 (In the right-hand state), to prevent multiple sheets of cardboard from being fed in, the feeding roller 18 presses down on the cardboard. Since the feeding roller 19 keeps rotating, the feeding roller 18 and the feeding roller 19 work together to feed the cardboard forward, and the cardboard is completely transferred to the cardboard conveying mechanism 2.

[0026] To drive the swing arm 181 to swing back and forth, such as Figure 4 As shown, a rotatable cam 184 is mounted on the feeding bracket 10. The cam 184 is connected to a power source. A force-receiving wheel 183 is connected to the swing arm 181. The cam 184 acts on the force-receiving wheel 183, causing the swing arm 181 to swing in one direction. A return spring 185 is connected between the feeding bracket 10 and the swing arm 181, allowing the swing arm 181 to swing in the opposite direction. Driven by the power source, the cam 184 rotates. Due to the reaction force of the spring 185, the force-receiving wheel 183 always presses against the curved surface of the cam 184, repeatedly oscillating along the curved surface of the cam. This allows the baffle plate 17 and the feeding pressure roller 18 to swing synchronously, achieving the desired effect. Figure 5 The two motion states are shown.

[0027] like Figure 2As shown, the paper stacking platform 11 is vertically mounted on the feeding bracket 10 (suspended by a chain), and is connected to a lifting power source that drives the paper stacking platform 11 to rise and fall. Driven by the lifting power source, the paper stacking platform 11 can move up and down. When a paper stack needs to be placed, the paper stacking platform 11 is lowered. After the paper stack is placed, as the paper feeder conveys the sheets of cardboard forward, the paper stacking platform 11 continuously rises, always keeping the top of the paper stack close to the paper feeder.

[0028] like Figure 6 As shown, the board feeding and correction mechanism 3 also includes a paper feed guide plate 30, a correction pressure roller 31 mounted on the paper feed guide plate 30, the paper feed guide plate 30 mounted on a side plate 32, and the side plate 32 mounted on the conveyor bracket 20. The side plate 32 is located on one side of the correction pressure roller 31. The correction pressure roller 31 presses against the cardboard and cooperates with the correction conveyor belt 21 to move the cardboard forward against the side plate 32.

[0029] As described above, a cardboard slotting mechanism 4 is provided at the discharge end of the cardboard conveying mechanism 2 for slotting the cardboard. Figure 7 As shown, the cardboard slotting mechanism 4 includes a slotting knife 41, a slotting roller 40, a pressure belt 43, and multiple tension rollers 42. The pressure belt 43 is wound around the multiple tension rollers 42, and the pressure belt 43 presses against the slotting roller 40 under the action of the multiple tension rollers 42. The slotting knife 41 is located on one side of the slotting roller 40. After the cardboard is corrected by the feeding and correction mechanism 3, it enters between the pressure belt 43 and the slotting roller 40. Under the action of the pressure belt 43, the cardboard bends and adheres to the slotting roller 40. The slotting roller 40 rotates under the drive of the power source, causing the cardboard and the pressure belt 43 to rotate together. The slotting knife 41 is located on one side of the slotting roller 40, and as the cardboard moves, the slotting knife 41 cuts a groove on the cardboard.
