Description

Technical Field

[0001] The utility model relates to the technical field of nesting machines, in particular to a nesting machine with an auxiliary material changing function. Background Art

[0002] Flatbed die-cutting machines and nesting die-cutting machines are the two most common devices in daily life. Nesting die-cutting machines generally refer to die-cutting machines that are used for punching positioning and perform front punching and back nesting operations. They are called nesting die-cutting machines. Nesting die-cutting machines add nesting lifting rods to ensure position registration and compound die-cutting in the actual die-cutting process of multi-layer structure die-cutting parts, thereby realizing the processing of the film to be cut.

[0003] In the prior art, a Chinese patent with authorization announcement number CN212498095U discloses a small hole sleeve machine, including a machine base, a frame and a driven roller, the top of the machine base is fixedly connected to the bottom of the frame, the driven roller is fixedly connected with a rotating shaft inside, the two ends of the rotating shaft are rotatably connected with connecting blocks, the left end of the frame is fixedly connected with a transmission top box, and the inner top wall of the transmission top box is fixedly connected with a guide rod. The small hole sleeve machine, by setting a rotating shaft, a connecting block, a slider, a spring, a tooth plate, a gear, a wheel axle, a chain, a long shaft, a pressure rod and a power rod, pulls the film to be cut from the feed roller, and places the end of the film to be cut away from the feed roller between the driven roller and the active roller, starts the servo motor to move the film to be cut, starts the cylinder, the output end of the cylinder drives the die-cutting plate to move downward, and at the same time the power rod presses the pressure rod downward, and the pressure rod drives the long shaft to rotate, which solves the problem that the current small hole sleeve machine has a too complicated mechanism, a large volume and weight, and a high maintenance cost.

[0004] The above mechanism utilizes a cylinder to move the die-cutting plate up and down and cut the film to be cut, thereby realizing the processing of the film to be cut. However, in actual use, the processing method of the positioning machine is already a mature production process. At the same time, when the positioning machine is in use, it is inconvenient to replace the entire feed roller, which affects the overall processing efficiency of the film to be cut. Utility Model Content

[0005] The purpose of the utility model is to provide a nesting machine with auxiliary material changing function to solve the problem in the background technology that the feeding roller is inconvenient to replace during the use of the nesting machine, which affects the overall processing efficiency of the film to be cut.

[0007] A connecting frame is fixedly connected to one side of the top of the fixed bottom plate close to the mounting frame, and a material discharge roller is clamped and connected to one end of the connecting frame, and an auxiliary material replacement mechanism for disassembling the material discharge roller is provided at one end of the connecting frame at both ends of the material discharge roller, and the auxiliary material replacement mechanism includes a limit frame, and the limit frame is fixedly connected to one end of the connecting frame, and a limit ring is provided above the limit frame;

[0008] Limiting blocks are arranged on both sides of the limiting ring, and limiting mechanisms for engaging the limiting ring and the limiting frame are arranged on the inner sides of the limiting blocks.

[0009] Furthermore, a fixed rod is fixedly connected to the top of the connecting frame, and a movable rod is fixedly connected to the inside of the fixed rod via a connecting spring, and the bottom end of the movable rod is connected to a limiting ring.

[0010] Furthermore, an elastic airbag is fixedly connected to the interior of the limiting frame, and the elastic airbag is connected to the fixing rod through a hose.

[0011] Furthermore, anti-skid bumps are arranged at equal intervals on the inner side of the elastic airbag, and the cross-section of the anti-skid bumps is semicircular.

[0012] Furthermore, the limiting mechanism includes a mounting block, and the mounting block is fixedly connected to two sides of the limiting frame, and the limiting block and the mounting block are engaged with each other.

[0013] Furthermore, one side of the limit block is engaged with a clamping block, and one side of the clamping block passes through and extends to the bottom of the mounting block.

[0014] Furthermore, a return spring is wound around the outer side of the clamping block, and the return spring is elastically connected to the limiting block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. In the process of material conveying, it is necessary to replace different unloading rollers in time according to the current situation, and clamp the unloading roller inside the limiting ring and the limiting frame. The gravity of the unloading roller can press the elastic airbag, so that the gas inside the elastic airbag is conveyed to the inside of the fixed rod through the hose. At the same time, the movable rod inside the fixed rod is pushed out by the gas, so that the gap between the limiting ring and the limiting frame is reduced, so that the unloading roller can be clamped more firmly. When the weight of the unloading roller decreases after conveying the material, the force of the unloading roller squeezing the elastic airbag is reduced, so that the gap between the limiting ring and the limiting frame is restored, so that the unloading roller can be quickly disassembled and replaced, which is convenient for better processing of the film to be cut;

[0017] The film to be cut can be transported by the discharge roller, and the film to be cut passes through one end between the fixed roller and the pressing roller, and the fixed roller and the pressing roller are driven by the rotation of the motor, so that the fixed roller and the pressing roller can press and tighten the film to be cut, so that the film to be cut can be in a tightened state, which can facilitate the cutting of the film to be cut, and the pneumatic telescopic rod is pressed downward so that the cutting piece contacts with the workbench, and at the same time, the cutting piece cuts the film to be cut, and when the sliding plate moves downward, the fixed block also moves downward and presses the fixed pressing plate, and at the same time, the fixed pressing plate is connected to the connecting plate, so that the pressing roller is driven and the distance between the fixed roller increases, and the output end of the pneumatic telescopic rod moves upward, and when it moves a certain distance, a certain distance is maintained between the fixed roller and the pressing roller. At this time, the fixed roller is driven by the motor to rotate, so that the fixed roller and the discharge roller cooperate with each other to transport the cut film, which is convenient for stable and rapid processing of the film to be cut;

[0018] Furthermore, the block inside the elastic airbag can increase the friction force when the elastic airbag contacts the unloading roller, so that the position of the unloading roller inside the limiting ring and the limiting frame can be more stable, which is convenient for effectively increasing the stability of the unloading roller during installation;

[0019] 2. When the limit ring and the limit frame are engaged, the limit blocks and mounting blocks on both sides of the limit ring and the limit frame will be engaged before the limit ring and the limit frame, so as to limit and guide the position of the limit ring and the limit frame when engaging, and avoid the position deviation of the limit ring and the limit frame during the engagement process;

[0020] Furthermore, since the mounting block is engaged with the limit block from below, the limit block will squeeze the block engaged on one side of the limit block to one side during the downward movement, thereby causing the return spring to be stressed and increase its length, and at the same time the block is squeezed to one side of the limit block. When the mounting block is engaged with the limit block, the block is reset by the elastic force of the return spring and limits the position of the mounting block. Since the lower end of the block is arc-shaped, it will move to one side along its own arc when squeezed. When the limit block moves upward, it will not be pushed to one side due to the flat upper end of the block, thereby playing a limiting role. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The technical solution shown is to solve the problem: the nesting machine with auxiliary material changing function discloses an auxiliary material changing mechanism, including a fixed base plate 1 and a fixed roller 2 rotatably connected to one side of the top of the fixed base plate 1, a rotating frame 3 is fixedly connected to the side of the top of the fixed base plate 1 close to the fixed roller 2, and one end between the rotating frames 3 is rotatably connected to a connecting plate 4, one end between the connecting plates 4 is rotatably connected to a pressing roller 5, the other end of one side between the connecting plates 4 is fixedly connected to a fixed pressing plate 12, a workbench 11 is fixedly connected to the middle position of the top of the fixed base plate 1, and a mounting frame 6 is fixedly connected to the top of the fixed base plate 1 above the workbench 11, a pneumatic telescopic rod 7 is fixedly connected to the middle position of the top inside the mounting frame 6, and the output end of the pneumatic telescopic rod 7 is fixedly connected to a sliding plate 8, and the bottom end of the sliding plate 8 is fixedly connected A cutting piece 10 is connected, and the cutting piece 10 is arranged above the workbench 11. A fixed block 9 is fixedly connected to one side of the sliding plate 8, and the fixed block 9 is arranged above the fixed pressing plate 12. A connecting frame 13 is fixedly connected to the side of the top of the fixed base plate 1 close to the mounting frame 6, and one end of the connecting frame 13 is clamped and connected with a feeding roller 25. One end of the connecting frame 13 at both ends of the feeding roller 25 is provided with an auxiliary material changing mechanism for disassembling the feeding roller 25. The auxiliary material changing mechanism includes a limit frame 18, and the limit frame 18 is fixedly connected to one end of the connecting frame 13. A limit ring 17 is arranged above the limit frame 18. A fixed rod 14 is fixedly connected to the top of the connecting frame 13, and a movable rod 16 is fixedly connected to the inside of the fixed rod 14 through a connecting spring 15, and the bottom end of the movable rod 16 is connected to the limit ring 17.

[0032] The film to be cut is conveyed by the discharge roller 25, and the film to be cut passes through one end between the fixed roller 2 and the pressing roller 5. The fixed roller 2 and the pressing roller 5 are driven by the rotation of the motor, so that the fixed roller 2 and the pressing roller 5 can press and tighten the film to be cut, so that the film to be cut can be in a tightened state, which can facilitate the cutting process of the film to be cut. The pneumatic telescopic rod 7 is pressed downward so that the cutting piece 10 contacts the workbench 11, and the cutting piece 10 cuts the film to be cut. When the sliding plate 8 moves downward, the fixed block 9 also moves downward and presses the fixed pressing plate 12. At the same time, the fixed pressing plate 12 is connected to the connecting plate 4, so that the pressing roller 5 is driven and the distance between the fixed roller 2 is increased. The output end of the pneumatic telescopic rod 7 moves upward. When it moves a certain distance, a certain distance is maintained between the fixed roller 2 and the pressing roller 5. At this time, the fixed roller 2 is driven by the motor to rotate, so that the fixed roller 2 and the feeding roller 25 cooperate with each other to convey the cut film. In the process of material conveying, it is necessary to replace different feeding rollers 25 in time according to the current situation, and the feeding roller 25 is clamped inside the limiting ring 17 and the limiting frame 18. The gravity of the feeding roller 25 can press the elastic airbag 21, so that the gas inside the elastic airbag 21 is conveyed to the inside of the fixed rod 14 through the hose. At the same time, the movable rod 16 inside the fixed rod 14 is pushed out by the gas, so that the gap between the limiting ring 17 and the limiting frame 18 is reduced, so that the feeding roller 25 can be clamped more firmly. When the weight of the feeding roller 25 is reduced after the material is conveyed, the force of the feeding roller 25 squeezing the elastic airbag 21 is reduced, so that the gap between the limiting ring 17 and the limiting frame 18 is restored, so that the feeding roller 25 can be quickly disassembled and replaced.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution shown is based on Example 1, in order to solve the problem: the sleeve machine with auxiliary material changing function discloses a limit mechanism, limit blocks 19 are arranged on both sides of the limit ring 17, and the inner side of the limit block 19 is arranged with a limit mechanism for engaging the limit ring 17 and the limit frame 18, the limit mechanism includes a mounting block 20, and the mounting block 20 is fixedly connected to both sides of the limit frame 18, the limit block 19 and the mounting block 20 are engaged with each other, one side of the limit block 19 is engaged with a clamping block 23, and one side of the clamping block 23 passes through and extends to the bottom of the mounting block 20, the outer side of the clamping block 23 is wound with a return spring 24, and the return spring 24 and the limit block 19 are elastically connected.

[0035] In this example, when the limit ring 17 and the limit frame 18 are engaged, the limit blocks 19 and the mounting blocks 20 on both sides of the limit ring 17 and the limit frame 18 will be engaged before the limit ring 17 and the limit frame 18, thereby realizing the position restriction and guidance of the limit ring 17 and the limit frame 18 when they are engaged, and avoiding the position deviation of the limit ring 17 and the limit frame 18 during the engagement process. Since the mounting block 20 is engaged with the limit block 19 from below, the limit block 19 will engage one side of the limit block 19 during the downward movement. The block 23 is squeezed to one side, so that the return spring 24 is stressed and increases its length. At the same time, the block 23 is squeezed to one side of the limit block 19. When the mounting block 20 is engaged with the limit block 19, the block 23 is reset by the elastic force of the return spring 24 and limits the position of the mounting block 20. Since the lower end of the block 23 is arc-shaped, it will move to one side along its own arc when squeezed. When the limit block 19 moves upward, the upper end of the block 23 is flat and cannot be squeezed and pushed to one side, thereby playing a limiting role.

[0036] Embodiment three:

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution shown is to solve the problem: the positioning machine with auxiliary material changing function discloses an anti-skid mechanism, an elastic airbag 21 is fixedly connected to the inside of the limiting frame 18, and the elastic airbag 21 is connected to the fixed rod 14 through a hose, and anti-skid protrusions 22 are arranged at equal intervals on the inner side of the elastic airbag 21, and the cross-section of the anti-skid protrusion 22 is semicircular.

[0038] In this example, the block 23 on the inner side of the elastic airbag 21 can increase the friction force when the elastic airbag 21 contacts the discharge roller 25, so that the position of the discharge roller 25 inside the limiting ring 17 and the limiting frame 18 can be more stable, thereby effectively increasing the stability of the discharge roller 25 during installation.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
