Description

Technical Field

[0001] This utility model relates to the field of packaging and printing production technology, specifically to a device for recycling edge materials in packaging and printing production. Background Technology

[0002] Packaging printing is printing on various packaging bag materials to print decorative patterns, designs, or text on the packaging bags, thereby making the products more attractive or informative and thus conveying information. During the production of packaging printing film, the edges of the film need to be cut during the winding stage. After cutting, the edge material is left directly on the ground and continues to accumulate, which not only affects the production environment of the film material, but also makes subsequent collection inconvenient and wastes too much manpower.

[0003] Therefore, in actual production, scrap material is collected and wound up using a specialized recycling device. This scrap material recycling device mainly includes a frame, on which a reciprocating drive mechanism for scrap material is installed. The reciprocating drive mechanism mainly consists of a rotatable reciprocating screw, with a support rod rotatably mounted at the other end of the screw. The support rod is connected to the frame. A crescent-shaped slider is fitted onto the reciprocating screw, and a reciprocating sleeve is fitted onto the outer side of the crescent-shaped slider. A sliding rod extends horizontally through the lower part of the reciprocating sleeve, and the sliding rod is parallel to the reciprocating screw. The two ends of the slide bar are connected to the support rod and the support plate, respectively. The upper part of the reciprocating sleeve is connected to the collar via a connecting rod. In use, a paper tube is mounted on the winding frame. One end of the edge material is passed through the collar and wound around the paper tube. Then, the winding frame is started to rotate. The motor on the reciprocating screw is turned on to make it rotate. As the winding frame rotates continuously, the cut edge material is wound around the paper tube. The reciprocating collar can adjust the winding position of the edge material on the paper tube, so that it is evenly wound on the paper tube and avoids accumulation in a certain position of the paper tube.

[0004] However, existing edge material recycling devices generally only have one winding rack. This means that when the paper tube is full of edge material, it needs to be replaced. Since the film production line is long, when the paper tube is full of edge material, the film is still being produced and trimmed. This results in some edge material accumulating on the ground again during the paper tube replacement period. As a result, a lot of edge material needs to be wound around the paper tube to match the trimming speed of the film. This method obviously increases labor and requires skilled workers to operate, so it has certain limitations. Utility Model Content

[0005] This utility model proposes an edge material recycling device for packaging and printing production, which solves the problem of increased labor caused by insufficient edge material winding on the winding frame of existing edge material recycling devices.

[0006] The technical solution of this utility model is as follows: an edge material recycling device for packaging and printing production, including a frame and an edge material reciprocating drive mechanism set on the frame, and also including a support plate, a turntable, a winding frame, a second drive component, and a film cutting mechanism. The support plate is installed on the frame and has a circular hole. The turntable is rotatably set in the circular hole by the first drive component. Three winding frames are provided, and the three winding frames are evenly arranged on the turntable. The second drive component is set on the turntable and is used to drive the winding frames to rotate. The film cutting mechanism is set on the support plate and is used to cut the edge material wrapped around the frame.

[0007] Preferably, the film cutting mechanism includes an L-shaped frame, a pressing assembly, and a heating wire. The L-shaped frame is located on one side of the turntable and is rotatably mounted on the support plate via a pivot shaft. The pressing assembly is rotatably disposed at the other end of the L-shaped frame for pressing the edge material onto the next winding frame. The heating wire is disposed inside the pressing assembly.

[0008] More preferably, the fastening assembly includes a support shaft, fastening plates, rollers, and paddles. The support shaft is rotatably mounted on the L-shaped frame. There are two fastening plates, and one end of each fastening plate is rotatably mounted on the support shaft. The rollers are rotatably mounted inside the fastening plates, and each fastening plate has at least two rollers. The rollers are arranged parallel to the support shaft. There are three paddles, and the three paddles are circumferentially equidistant on the outer wall of the turntable to drive the actuation shaft to rotate. The paddles have teeth on their sides, and the actuation shaft has multiple grooves on its outer wall.

[0009] Based on the aforementioned scheme, further, a sleeve is provided at one end of the buckle plate that is rotatably connected to the support shaft, and the sleeves on the two buckle plates are staggered. A spring piece is connected to the outer wall of the sleeve, and the other end of the spring piece is slidably disposed on the outer wall of the opposite buckle plate, with the spring piece abutting against the outer wall of the buckle plate.

[0010] Based on the aforementioned scheme, the driving component one further includes a motor one, a gear one, and a gear ring one. The motor one is mounted on the frame, the gear one is coaxially connected to the output end of the motor one, and the gear ring one is fitted on the outside of the turntable and meshes with the gear one.

[0011] Furthermore, based on the aforementioned scheme, positive and negative electrode rods are respectively provided at both ends of the turntable, the heating wire is arranged parallel to the support shaft, and both ends of the heating wire are electrically connected to the positive and negative electrode rods respectively.

[0012] To facilitate the placement and removal of the paper tube, the winding frame includes a drive plate, a baffle plate, and elastic rods. The drive plate is rotatably connected to the outer wall of the turntable, and the baffle plate is coaxially connected to the other side of the drive plate. Multiple elastic rods are circumferentially connected to the other end of the baffle plate. The elastic rods are hook-shaped and have a chamfered structure on the side away from the baffle plate.

[0013] Based on the aforementioned scheme, the second driving component includes a second motor, a second gear, and a second gear ring. The second motor is positioned above the first motor and is fixedly mounted on the frame via a bracket. The second gear is concentrically positioned on the turntable near the winding frame, and the output shaft of the second motor passes through the center of the turntable and is concentrically connected to the second gear. The output shaft of the second motor rotates with the center of the turntable, and a gap is left between the second gear and the turntable. The second gear ring is fitted onto the driving disk and meshes with the second gear.

[0014] To prevent the L-shaped frame from rotating arbitrarily when the lever is turned, a tension spring is also provided on the outer wall of the L-shaped frame, and the other end of the tension spring is connected to the support plate through a mounting plate.

[0015] To prevent the support shaft from rotating arbitrarily within the L-shaped frame, the L-shaped frame is provided with a rotating groove for the support shaft to rotate, and two limiting grooves are symmetrically arranged within the rotating groove. Two limiting blocks are symmetrically arranged on the support shaft, and the limiting blocks are slidably arranged within the limiting grooves.

[0016] To improve the transition of edge material between two adjacent take-up frames, an arc-shaped plate is also provided. Three arc-shaped plates are provided, equidistant from each other and circumferentially mounted on the turntable, with the arc-shaped plates positioned between two adjacent take-up frames.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this invention, three winding racks can simultaneously hold three paper tubes. After the paper tube on one of the winding racks has finished collecting edge material (the uppermost winding rack is designed to directly collect edge material in conjunction with the edge material reciprocating mechanism), the turntable's angular movement can adjust the three winding racks on the turntable to their set positions. This allows the wound paper tube to be rotated to the rear, while the paper tube without edge material continues to be rotated to the usage position. During the paper tube switching, the film cutting mechanism works in synergy with the turntable's rotation. As the next paper tube switches to the usage position, the film cutting mechanism cuts off the edge material and attaches it to the next unwound paper tube for continued winding and edge collection. This achieves rapid switching, reducing the accumulation of edge material on-site during paper tube replacement as in traditional technologies, and improving the efficiency of edge material collection.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-9 As shown, this embodiment proposes an edge material recycling device for packaging printing production, including a frame 1 and an edge material reciprocating drive mechanism 2 mounted on the frame 1. It also includes a support plate 3, a turntable 4, a winding rack, a second drive component, and a film cutting mechanism. The support plate 3 is mounted on the frame 1 and has a circular hole. The turntable 4 is rotatably mounted in the circular hole via the first drive component. Three winding racks are evenly distributed circumferentially on the turntable 4. The second drive component is mounted on the turntable 4 to drive the winding racks to rotate. The film cutting mechanism is mounted on the support plate 3 to cut the wrapped edge material. By using three winding racks, three paper tubes can be placed simultaneously. When one winding rack... After the paper tubes have finished collecting the edge material (the uppermost winding frame is set to directly collect the edge material in conjunction with the edge material reciprocating drive mechanism 2), the three winding frames on the turntable 4 can be adjusted to their used positions according to the set angles through the equal-angle movement of the turntable 4. This allows the wound paper tubes to be rotated to the rear, while the paper tubes without edge material are rotated to the used position. During the paper tube switching, the film cutting mechanism works in synergy with the rotation of the turntable 4. As the next paper tube switches to the used position, the film cutting mechanism can cut off the edge material and attach it to the next paper tube without edge material for continued winding and edge collection, thus achieving rapid switching.

[0032] like Figures 1-2 As shown, the edge material reciprocating drive mechanism 2 is a known technology. It includes a drive motor, which is mounted on a support plate 3. The output shaft of the drive motor rotates and passes through the support plate 3, connecting to a reciprocating screw. A support rod is rotatably mounted on the other end of the reciprocating screw, and the support rod is connected to the frame 1. A crescent-shaped slider that is threaded into the reciprocating screw is fitted on the reciprocating screw, and a reciprocating sleeve is fitted on the outer side of the crescent-shaped slider. A sliding rod passes horizontally through the lower part of the reciprocating sleeve, and the sliding rod is parallel to the reciprocating screw. Both ends of the sliding rod are connected to the support rod and the support plate 3, respectively. A collar is connected to the upper part of the reciprocating sleeve via a connecting rod. During use, the edge material rotates through the collar and wraps around the paper tube. As the paper tube rotates, the edge material moves along the paper tube, and the drive motor... Driven by the mechanism, the reciprocating screw rotates, thereby causing the reciprocating sleeve to slide back and forth on the reciprocating screw, evenly winding the edge material onto the paper tube. The reciprocating screw mechanism is a well-known device in the field of edge material recycling machines. The driving component includes a motor 5, a gear 6, and a gear ring 7. The motor 5 is mounted on the frame 1, the gear 6 is coaxially connected to the output end of the motor 5, and the gear ring 7 is fitted on the outside of the turntable 4 and meshes with the gear 6. The rotation of the motor 5 can drive the gear 6 to rotate, thereby driving the gear ring 7 to rotate. Under the rotation of the gear ring 7, the turntable 4 can rotate within the circular hole, realizing the intermittent switching of the three winding frames.

[0033] like Figures 1-6As shown, the film cutting mechanism includes an L-shaped frame 8, a clamping assembly, and a heating wire 9. The L-shaped frame 8 is located on one side of the turntable 4 and is rotatably mounted on the support plate 3 via a toggle shaft. The clamping assembly is rotatably mounted on the other end of the L-shaped frame 8 and is used to clamp the edge material onto the next winding frame. The heating wire 9 is located inside the clamping assembly. The clamping assembly includes a support shaft 10, clamping plates 11, rollers 12, and toggle pieces 13. The support shaft 10 is rotatably mounted on the L-shaped frame 8. There are two clamping plates 11, and one end of each clamping plate 11 is rotatably mounted on the support shaft 10. The rollers 12 are rotatably mounted inside the clamping plates 11, and each clamping plate 11 has at least two rollers 12. The rollers 12 are arranged parallel to the support shaft 10. There are three toggle pieces 13. Furthermore, the three paddles 13 are circumferentially equidistantly arranged on the outer wall of the turntable 4 to drive the actuating shaft to rotate. The paddles 13 have teeth 14 on their sides, and the actuating shaft has multiple grooves on its outer wall. Due to the arrangement of the paddles 13, when the turntable 4 rotates and switches the winding rack, the paddles 13 are in contact with the actuating shaft. The grooves on the actuating shaft contact the teeth 14 on the paddles 13, increasing the friction between the paddles 13 and the actuating shaft. This allows the L-shaped frame 8 to rotate around the actuating shaft, thus allowing the buckle plate 11 to be fastened onto the switched winding rack. It should be noted that in this embodiment, the winding rack rotated to the uppermost position is the winding rack used for edge winding. When the turntable 4 rotates to switch the winding rack, the winding rack that has finished winding rotates to the left. Please refer to the attached diagram. Figure 3 When the new winding rack rotates to the top, some of the edge material is passed between the original and new winding racks. When the buckle plate 11 presses down on the new winding rack, the edge material is instantly cut off by the heating wire 9. After being cut off, some of the edge material continues to wrap around the original winding rack as it rotates. Due to the instant the heating wire 9 cuts, the cut point melts to some extent, so it can be stuck to the new winding rack (on the paper tube inserted into the winding rack) under the pressure of the buckle plate 11. Therefore, under the pressure of the buckle plate 11, the edge material can continue to wrap around the paper tube on the new winding rack as it rotates. After wrapping is complete, the above steps are repeated to achieve replacement. By setting and switching between three winding racks, the time for operators to replace the next paper tube is saved, the accumulation of edge material on site is reduced, and the efficiency of edge material recycling is improved.

[0034] like Figures 1-6As shown, a sleeve is provided at one end of the buckle plate 11 that is rotatably connected to the support shaft 10, and the sleeves on the two buckle plates 11 are staggered. A spring piece 16 is connected to the outer wall of the sleeve, and the other end of the spring piece 16 is slidably disposed on the outer wall of the opposite buckle plate 11. The spring piece 16 abuts against the outer wall of the buckle plate 11. By setting the spring piece 16, the pressure of the buckle plate 11 on the edge material on the winding frame can be enhanced, so that the edge material can better adhere to the paper tube. Positive and negative electrode rods are respectively provided at both ends of the turntable 4. The heating wire 9 is arranged parallel to the support shaft 10, and both ends of the heating wire 9 are electrically connected to the positive and negative electrode rods respectively. By setting the positive and negative electrode rods, the heating wire can be energized to achieve the purpose of cutting the plastic edge material.

[0035] like Figure 1 and Figure 9 As shown, to facilitate the placement and removal of the paper tube, the winding frame includes a drive disk, a baffle 17, and elastic rods 18. The drive disk is rotatably connected to the outer wall of the turntable 4, and the baffle 17 is coaxially connected to the other side of the drive disk. Multiple elastic rods 18 are circumferentially connected to the other end of the baffle 17. The elastic rods 18 are hook-shaped, and the side of the elastic rods 18 away from the baffle 17 is provided with a chamfer structure. By setting multiple elastic rods 18, it is easy for the paper tube to be directly fitted onto the winding frame, and it can also be directly pulled out after winding, which is convenient to operate. The circular shaft arrangement of multiple elastic rods 18 can enhance the support stability of the paper tube.

[0036] like Figures 1-2 As shown, the second driving component includes a second motor 19, a second gear 20, and a second gear ring 21. The second motor 19 is positioned above the first motor 5 and is fixedly mounted on the frame 1 via a bracket. The second gear 20 is concentrically positioned on the turntable 4 near the winding frame, and the output shaft of the second motor 19 passes through the center of the turntable 4 and is concentrically connected to the second gear 20. The output shaft of the second motor 19 rotates with the center of the turntable 4, and there is a gap between the second gear 20 and the turntable 4. The second gear ring 21 is fitted onto the driving disk and meshes with the second gear 20. The rotation of the second motor 19 can drive the second gear 20 to rotate. The second gear 20 is located in the center of the three second gear rings 21, so it can drive the three second gear rings 21 to rotate simultaneously, thereby driving the rotation of the winding frame.

[0037] like Figure 7As shown, to prevent the L-shaped frame 8 from rotating arbitrarily under the action of the lever 13, a tension spring 15 is also provided on the outer wall of the L-shaped frame 8, and the other end of the tension spring 15 is connected to the support plate 3 through a mounting plate. To prevent the support shaft 10 from rotating arbitrarily within the L-shaped frame 8, a rotating groove 22 for the rotation of the support shaft 10 is provided on the L-shaped frame 8, and two limiting grooves are symmetrically arranged in the rotating groove 22. Two limiting blocks 23 are symmetrically arranged on the support shaft 10, and the limiting blocks 23 are slidably disposed on the support shaft 10. The rotation angle of the support shaft 10 is limited within the limiting groove, allowing it to effectively engage with the winding frame for collecting edge material. To improve the transition of edge material between two adjacent winding frames, an arc-shaped plate 24 is also provided. Three arc-shaped plates 24 are provided, equidistantly and circumferentially mounted on the turntable 4. The arc-shaped plates 24 are located between two adjacent winding frames. Through the three arc-shaped plates 24 and the three winding frames, a circular frame can be formed on one side of the turntable 4, which can better support the edge material.

[0038] In this embodiment, the edge material recycling device for packaging and printing production requires the following steps: First, three paper tubes are respectively mounted on three winding frames and supported by elastic rods 18 on the winding frames. The rotation angle of motor 15 is set, and the three winding frame shafts are set at equal angles. The rotation of motor 29 drives the three winding frames to rotate. When collecting edge material, the edge material passes through the collar on the edge material reciprocating drive mechanism 2 and is wound around the uppermost paper tube. The drive motor and motor 29 are turned on, so that the edge material moves with the reciprocating collar and is wound around the paper tube with the rotation of the winding frame. When the edge material on the uppermost paper tube is fully wound (but the new paper tube has not yet reached the top), motor 15 is turned on, so that the turntable 4 rotates counterclockwise. When the turntable 4 has not rotated 120 degrees, that is, less than 120 degrees (please refer to...), the edge material is collected when the edge material is collected when the edge material on the uppermost paper tube is fully wound (but the new paper tube has not yet reached the top). Figure 3 At this time, the paddle 13 also comes to the bottom of the actuating shaft as the turntable 4 rotates, causing the L-shaped frame 8 to rotate and press the buckle 11 onto the outer wall of the paper tube that has rotated to the top again. At the same time, the heating wire 9 cuts off the edge material. After the cutting is completed, the turntable 4 continues to rotate and rotates to 120 degrees. At this time, the paddle 13 passes around the actuating shaft, and the L-shaped frame resets under the tension of the tension spring 15 and moves the buckle 11 away from the top paper tube. Then the cut edge material continues to be wound on the new paper tube. When the turntable 4 rotates, the paddle 13 rotates with the turntable 4, and the buckle 11 is fastened on the new paper tube. The cutting of the edge material by the heating wire 9 is very fast, so the motor 5 can be set to rotate 120 degrees each time to realize the above paper tube switching operation. Since the paper tube full of edge material is only supported by the elastic rod 18 and the rotation speed of the winding frame is not high speed, it can be directly pulled out and placed.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
