Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, and particularly relates to a pre-press exhaust conveying device. Background Art

[0002] In the production and processing machinery and equipment of wine gift bags, there are often conveying devices such as conveyor belts to convey the produced gift bags. After several processes, they are finally stacked and sealed in boxes.

[0003] When several gift bags are stacked, since the surface of the newly produced gift bags is attached with a film, and the film may contain air, resulting in blisters, which will not only cause poor stacking effect, but also affect the production quality. In the prior art, to solve this problem, an elastic extrusion device is usually adopted to extrude the gift bags between the elastic extrusion device and the conveying surface, so as to discharge the air in the film during the conveying process. However, since the elastic extrusion device has no conveying power and the extrusion friction is large, the conveying speed of the gift bags may slow down or even rebound and jump during the extrusion process, and noise is generated by friction, which is not conducive to the assembly line production of gift bags. Content of the Utility Model

[0004] In order to solve the deficiencies of the prior art, the purpose of the utility model is to provide a pre-press exhaust conveying device. By adopting this solution, a secondary conveyor belt with the same conveying power is arranged above. While pre-pressing and exhausting by squeezing the surface of the gift bags at the end, the conveying speed of the gift bags remains unchanged, the conveying is stable, and the noise is small.

[0005] The utility model is realized by the following technical solutions:

[0006] A pre-press exhaust conveying device includes:

[0007] A main conveyor belt;

[0008] A secondary conveyor belt, which is located above the inlet section of the main conveyor belt. There is a clamping gap between the conveying surfaces of the secondary conveyor belt and the main conveyor belt that face each other, and the conveying speed and direction are the same.

[0009] An angle adjustment component, which is connected to the secondary conveyor belt and is used to drive the secondary conveyor belt to be inclined relative to the main conveyor belt. The inclined setting means that one end of the secondary conveyor belt is inclined towards the direction close to the main conveyor belt.

[0010] In the prior art, an elastic extrusion device is usually adopted to extrude a gift bag through the extrusion between the device and the conveying surface, so as to discharge the air in the film during the conveying process. However, since the elastic extrusion device has no conveying power and the extrusion friction is relatively large, the conveying speed of the gift bag may be slowed down or even bounce back during the extrusion process, and noise is generated by friction, which is not conducive to the production of gift bags on the assembly line. The present utility model provides a pre-pressuring and exhausting conveying device. By adopting this solution, a secondary conveyor belt with the same conveying power is arranged above, and while pre-pressuring and exhausting by extruding the surface of the gift bag through the end part, the conveying speed of the gift bag is kept unchanged, the conveying is stable, and the noise is small. In a specific solution, it includes a main conveyor belt for sequentially conveying a plurality of gift bags. The gift bags are folded into a plate shape and placed flat on the main conveyor belt for conveying. The secondary conveyor belt is located above the inlet section of the main conveyor belt, and there is a gap between the two. In this way, the gift bags can pass through the gap between the facing conveying surfaces of the main conveyor belt and the secondary conveyor belt. It also has an angle adjustment component for adjusting the inclination angle of the secondary conveyor belt. Through the angle adjustment component, the secondary conveyor belt can be driven to be inclined relative to the main conveyor belt. In this way, only one end of the secondary conveyor belt is used to extrude the surface of the gift bag, and a better extrusion effect can be achieved. In addition, the angle adjustment component drives one end of the secondary conveyor belt to incline towards the direction close to the main conveyor belt. In this way, the clamping distance between the main conveyor belt and the secondary conveyor belt can be adjusted through the angle adjustment component to match the thickness of the corresponding gift bag. In the above solution, servo motors for controlling the speed are provided on both the main conveyor belt and the secondary conveyor belt. By controlling that the facing conveying surfaces of the main conveyor belt and the secondary conveyor belt have the same conveying direction and speed, the gift bags can be synchronously driven to be conveyed forward without slowing down the conveying speed of the gift bags. Moreover, the secondary conveyor belt only gives a downward pressure to the gift bags without resistance in the conveying direction, so it will not bounce back and generate noise by friction. Its conveying is stable and there is almost no noise.

[0011] As a specific implementation manner of the angle adjustment component, the angle adjustment component includes a connecting rod and a hinged rod. One end of the connecting rod is connected to the end of the secondary conveyor belt and is used to push the end of the secondary conveyor belt to move away from or close to the main conveyor belt. The hinged rod is hinged between the same sides of the main conveyor belt and the secondary conveyor belt. Among them, by pulling or pushing the connecting rod, the change of the angle can be realized under the action of the hinged rod.

[0012] To realize the change of the angle of the secondary conveyor belt and the connection stability, two hinged rods are arranged at the same side positions of the main conveyor belt and the secondary conveyor belt. The two hinged rods are parallel to each other and have different lengths. Among them, by connecting with hinged rods of different lengths to form a variable quadrilateral structure, in this way, the secondary conveyor belt can be inclined relative to the main conveyor belt.

[0013] To achieve quick disassembly and assembly, a number of positioning blocks are detachably connected to the side walls of the main conveyor belt and the auxiliary conveyor belt along their respective lengths, and both ends of the hinge rod are respectively hinged to the positioning blocks of the main conveyor belt and the auxiliary conveyor belt.

[0014] To adjust the position of the hinge point in the hinge rod, a number of bolt holes are provided on the positioning block, and chutes are provided on the side walls of the main conveyor belt and the auxiliary conveyor belt along their respective lengths. The positioning block is inserted into the chute through a bolt. Among them, after the adjustment is in place, the bolt is tightened against the bottom of the chute.

[0015] To achieve stable driving of the connecting rod, the angle adjustment assembly further includes vertical frames fixed to both sides of the main conveyor belt and side plates fixed to both sides of the auxiliary conveyor belt. A first cross bar is rotatably connected between the two vertical frames, and a second cross bar is rotatably connected between the two side plates. One end of the connecting rod passes through the first cross bar and is rotatably connected to the second cross bar. The connecting rod is a lead screw and is threadedly connected to the first cross bar; the other end of the connecting rod is inclined upward relative to the main conveyor belt. In this solution, the connecting rod is a lead screw, its end is rotatably connected to the second cross bar, and the middle is threadedly connected to the second cross bar. Therefore, under the rotation of the lead screw, displacement in its own length direction is achieved, thereby driving the end of the auxiliary conveyor belt to move; in addition, the first cross bar and the second cross bar are rectangular bars, and both ends are rotatably connected, that is, the first cross bar and the second cross bar can rotate around themselves. Due to the driving of the connecting rod, the connecting rod itself will inevitably change its angle. Therefore, through the rotation of the first cross bar and the second cross bar, the deflection direction of the connecting rod can be adapted.

[0016] To facilitate driving the rotation of the connecting rod, a turntable is coaxially provided at the other end of the connecting rod, and a handle is provided on the turntable.

[0017] When the gift bag is conveyed to the stacking machine, to adapt to the relatively high height of the inlet of the stacking machine and save space, the main conveyor belt further includes an inclined section connected to the inlet section and an outlet section connected to the inclined section. The end of the inclined section away from the inlet section is inclined upward.

[0018] To limit the conveying path of the gift bag, baffles are provided on both sides of the conveying surfaces of the inclined section and the outlet section, and the distance between the two side baffles is adjustable. Among them, a number of lifting rings can be provided on the outer side wall of the baffle. The lifting rod is sleeved through the lifting ring, and the lifting ring is provided with a locking mechanism, which can lock or loosen the lifting rod. When the lifting rod is loosened, the lifting rod can move in its own length direction. Since the end of the lifting rod is connected to the baffle, the baffle can be driven to displace.

[0019] To guide the gift bag into the space between the two side baffles, the two side baffles form a flared opening at the starting end position of the inclined section.

[0020] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0021] The utility model provides a pre-press exhaust conveying device. By adopting this solution, a secondary conveyor belt with the same conveying power is arranged above. While pre-pressing and exhausting by squeezing the surface of the gift bag at the end, the conveying speed of the gift bag remains unchanged, the conveying is stable, and the noise is small.

[0027] In order to make the purpose, technical solutions and advantages of the utility model clearer and more understandable, the utility model will be further described in detail below in conjunction with the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the utility model are only used to explain the utility model and do not constitute a limitation to the utility model.

[0028] Embodiment

[0029] This embodiment provides a pre-press exhaust conveying device, as Figure 1 - Figure 2 shown, including:

[0030] main conveyor belt 101;

[0031] secondary conveyor belt 102, the secondary conveyor belt 102 is located above the inlet section of the main conveyor belt 101, and there is a clamping gap between the facing conveying surfaces of the secondary conveyor belt 102 and the main conveyor belt 101, and the conveying speeds and directions are the same;

[0032] An angle adjustment component, which is connected to the secondary conveyor belt 102 and is used to drive the secondary conveyor belt 102 to be inclined relative to the primary conveyor belt 101. The inclination is such that one end of the secondary conveyor belt 102 is inclined towards the direction close to the primary conveyor belt 101.

[0033] Compared with the prior art, an elastic extrusion device is usually adopted to squeeze the gift bag through the extrusion between the elastic extrusion device and the conveying surface, so as to discharge the air in the film during the conveying process. However, since the elastic extrusion device has no conveying power and the extrusion friction is large, the conveying speed of the gift bag may be slowed down or even bounce back during the extrusion process, and noise is generated by friction, which is not conducive to the production of gift bags on the assembly line. The present utility model provides a pre-press exhaust conveying device. By adopting this solution, a secondary conveyor belt 102 with the same conveying power is arranged above. While pre-pressing and exhausting the surface of the gift bag by squeezing the end part, the conveying speed of the gift bag is kept unchanged, the conveying is stable, and the noise is small. In a specific solution, it includes a primary conveyor belt 101 for sequentially conveying a plurality of gift bags. The gift bags are folded into a plate shape and placed flat on the primary conveyor belt 101 for conveying. The secondary conveyor belt 102 is located above the inlet section of the primary conveyor belt 101, and there is a gap between the two. In this way, the gift bag can pass through the gap between the opposite conveying surfaces of the primary conveyor belt 101 and the secondary conveyor belt 102. It also has an angle adjustment component for adjusting the inclination angle of the secondary conveyor belt 102. Through the angle adjustment component, the secondary conveyor belt 102 can be driven to be inclined relative to the primary conveyor belt 101. In this way, only one end of the secondary conveyor belt 102 is used to squeeze the surface of the gift bag, and a better squeezing effect can be achieved. In addition, the angle adjustment component drives one end of the secondary conveyor belt 102 to be inclined towards the direction close to the primary conveyor belt 101. In this way, the clamping distance between the primary conveyor belt 101 and the secondary conveyor belt 102 can be adjusted through the angle adjustment component to match the thickness of the corresponding gift bag. In the above solution, servo motors for controlling the speed are provided on both the primary conveyor belt 101 and the secondary conveyor belt 102. By controlling that the opposite conveying surfaces of the primary conveyor belt 101 and the secondary conveyor belt 102 have the same conveying direction and speed, the gift bag can be synchronously driven forward without slowing down the conveying speed of the gift bag. And the secondary conveyor belt 102 only gives a downward pressure to the gift bag without resistance in the conveying direction, so it will not bounce back and generate noise by friction. Its conveying is stable and there is almost no noise.

[0034] As a specific implementation of an angle adjustment component, the angle adjustment component includes a connecting rod 107 and a hinge rod 108. One end of the connecting rod 107 is connected to the end of the secondary conveyor belt 102 and is used to push the end of the secondary conveyor belt 102 to move away from or close to the main conveyor belt 101. The hinge rod 108 is hinged between the same sides of the main conveyor belt 101 and the secondary conveyor belt 102. Among them, by pulling or pushing the connecting rod 107, the change of the angle can be realized under the action of the hinge rod 108.

[0035] To achieve the change of the angle of the secondary conveyor belt 102 and the connection stability, two hinge rods 108 are provided at the same side positions of the main conveyor belt 101 and the secondary conveyor belt 102. The two hinge rods 108 are parallel to each other and have different lengths. Among them, by connecting the hinge rods 108 with different lengths, a variable quadrilateral structure is formed. In this way, the secondary conveyor belt 102 can be inclined relative to the main conveyor belt 101.

[0036] To achieve quick disassembly and assembly, a plurality of positioning blocks 109 are detachably connected to the side walls of the main conveyor belt 101 and the secondary conveyor belt 102 along their own length directions. Both ends of the hinge rod 108 are respectively hinged to the positioning blocks 109 of the main conveyor belt 101 and the secondary conveyor belt 102.

[0037] To achieve the adjustment of the hinge point position in the hinge rod 108, the positioning block 109 is provided with a plurality of bolt holes. The side walls of the main conveyor belt 101 and the secondary conveyor belt 102 are provided with chutes along their own length directions. The positioning block 109 is inserted into the chute by bolts. Among them, after the adjustment is in place, tighten the bolts against the bottom of the chute.

[0038] To achieve stable driving of the connecting rod 107, the angle adjustment assembly further includes vertical frames 103 fixed to both sides of the main conveyor belt 101 and side plates 104 fixed to both sides of the auxiliary conveyor belt 102. A first cross bar 105 is rotatably connected between the two vertical frames 103, and a second cross bar 106 is rotatably connected between the two side plates 104. One end of the connecting rod 107 passes through the first cross bar 105 and is rotatably connected to the second cross bar 106. The connecting rod 107 is a lead screw and is threadedly connected to the first cross bar 105; the other end of the connecting rod 107 is inclined upward relative to the main conveyor belt 101. In this solution, the connecting rod 107 is a lead screw, its end is rotatably connected to the second cross bar 106, and its middle part is threadedly connected to the second cross bar 106. Therefore, under the rotation of the lead screw, displacement in its own length direction is achieved, thereby driving the end of the auxiliary conveyor belt 102 to move; in addition, the first cross bar 105 and the second cross bar 106 are rectangular bars, and both ends are rotatably connected, that is, both the first cross bar 105 and the second cross bar 106 can rotate around themselves. Due to the driving of the connecting rod 107, the angle of the connecting rod 107 itself will inevitably change. Therefore, through the rotation of the first cross bar 105 and the second cross bar 106, the deflection direction of the connecting rod 107 can be adapted.

[0039] To facilitate driving the rotation of the connecting rod 107, a turntable 110 is coaxially provided on the other end of the connecting rod 107, and a handle is provided on the turntable 110.

[0040] When the gift bag is conveyed to the laminating machine, to adapt to the relatively high height of the inlet of the laminating machine and save space, the main conveyor belt 101 further includes an inclined section connected to the inlet section and an outlet section connected to the inclined section. The end of the inclined section away from the inlet section is inclined upward.

[0041] To limit the conveying path of the gift bag, baffles 111 are provided on both sides of the conveying surfaces of the inclined section and the outlet section, and the distance between the two side baffles 111 is adjustable. Among them, a number of hanging rings can be provided on the outer side wall of the baffle 111. The jacking rod is sleeved through the hanging ring, and the hanging ring is provided with a locking mechanism that can lock or loosen the jacking rod. When the jacking rod is loosened, the jacking rod can move in its own length direction. Since the end of the jacking rod is connected to the baffle 111, the baffle 111 can be driven to displace.

[0042] To guide the gift bag into the space between the two side baffles 111, the two side baffles 111 form a flared opening at the starting end position of the inclined section.

[0043] The specific embodiments described above have further elaborated in detail the purpose, technical solution and beneficial effects of the present utility model. It should be understood that the above description is only the specific embodiments of the present utility model and is not used to limit the protection scope of the present utility model.
