Description

Technical Field

[0001] This utility model relates to the technical field of plastic cup production equipment, specifically a conveyor for producing plastic cups with protective functions. Background Technology

[0002] Plastic cups, as a widely used everyday item, are popular with consumers due to their lightweight, durability, low cost, and ease of manufacture. They are commonly used for serving beverages and can be found in homes, offices, and public places. With the development of plastic processing technology, the materials used for plastic cups have evolved from a single type of polyethylene (PE) to a variety of materials such as polypropylene (PP) and polystyrene (PS) to meet the needs of different occasions and uses.

[0003] In the existing plastic cup production process, blow molding or vacuum forming are common manufacturing methods. After molding, compressed air is usually used to blow the plastic cup out of the mold and send it directly into the transport equipment for posture adjustment so that it can be stacked and packaged later. However, this method has some problems.

[0004] During the process of being blown into the conveyor equipment by compressed air, there are no effective protective measures to prevent plastic cups from being damaged. Since the plastic cups are newly formed, direct impact may cause deformation or scratches, affecting product quality. In addition, when using compressed air to blow plastic cups, a stronger compressed air is required in order to blow out the plastic cups on the side away from the conveyor equipment as well. This may cause the plastic cups close to the conveyor equipment to be blown out of the conveyor equipment range and fall outside the conveyor equipment or onto the ground, where they may be contaminated.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a conveyor for producing plastic cups with protective functions, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a conveyor for producing plastic cups with protective functions, including a blow molding machine and a collection box disposed on one side of the blow molding machine. Two baffles are fixed to the top of the collection box at both ends along its width direction. The same conveying device is provided at the top of the two inner walls of the collection box along its width direction. The conveying device includes multiple sets of conveyor belts evenly distributed along the width direction of the collection box. Each set of conveyor belts includes two parallel conveyor belts, the distance between the two conveyor belts being slightly larger than the width of the baffles. The distance between adjacent sets of conveyor belts matches the size of the product to be produced. A common housing is rotatably connected to the side wall of the two baffles that are close to each other. The length direction of the housing is consistent with the width direction of the collection box. The housing has a hollow structure. An interception mechanism is provided on the side of the housing away from the conveying device. The interception mechanism includes:

[0008] There are several baffles, which are rotatably set on the side of the shell away from the transport equipment and are evenly distributed along the length of the shell. Each baffle has a fixed shaft at the center of the side wall near the shell, and the fixed shaft passes through the shell and is set inside the shell.

[0009] The scissor lift is installed inside the housing, and its extension and retraction direction is consistent with the length direction of the housing. The scissor lift includes several scissor arm assemblies, and several fixed shafts correspond one-to-one with the several scissor arm assemblies. The fixed shafts are coaxially fixed to the middle of the scissor arm assemblies.

[0010] A ring-shaped toothed disc is coaxially fixed to the middle of the scissor arm assembly at one end of the scissor lift, near the side of the transport equipment. A bevel gear is meshed on the side of the ring-shaped toothed disc away from the center of the housing. A drive mechanism is fixed on the side of the bevel gear away from the center of the housing. The drive mechanism is located on the outer side of the baffle.

[0011] Furthermore, the scissor lift frame includes several scissor arm assemblies, each including a scissor arm 1 and a scissor arm 2 that are rotatably connected to each other. The ends of scissor arms 1 and scissor arms 2 that are not in the same assembly in adjacent scissor arm assemblies are rotatably connected to each other. A fixed shaft is fixed to the rotatable connection point of scissor arms 1 and scissor arms 2 in the scissor arm assemblies. On the side of the rotatable connection point of scissor arms 1 and scissor arms 2 away from the transport equipment, pulley 1 is coaxially rotatably connected to each other. On the side of the rotatable connection point of adjacent scissor arm assemblies away from the transport equipment and away from the blow molding equipment, pulley 2 is coaxially rotatably connected to each other. The pulley 2 has the same belt fitted in the groove of its adjacent pulley 1 on both sides, and the grooves of two adjacent pulley 2 are not at the same horizontal height.

[0012] Furthermore, one end of the housing is provided through a baffle plate on that side, and a driving mechanism is provided at the end of the housing that passes through the baffle plate. The driving mechanism includes a transmission shaft coaxially fixed to a bevel gear. The axial direction of the transmission shaft is parallel to the axial direction of the housing. The end of the transmission shaft away from the bevel gear passes through the housing. A limiting plate is fixed on the side wall of the housing that passes through the baffle plate. The limiting plate is sleeved on the outside of the transmission shaft. A motor is fixed at the end of the transmission shaft away from the bevel gear. A support plate is fixed at the bottom of the motor. A cylinder is fixed at the top of the motor. A limiting plate is fixed at the output end of the cylinder. The longitudinal section of the limiting plate along the axial direction of the transmission shaft is "door" shaped. The notch of the limiting plate faces the transmission shaft. A turntable is sleeved on the outer arc wall of the transmission shaft corresponding to the notch of the limiting plate.

[0013] Furthermore, the turntable is located between the motor and the limiting plate. A spline sleeve is fixed on the inner arc wall of the turntable, and a spline is fixed on the outer arc wall of the transmission shaft at a position corresponding to the turntable. Several limiting posts are fixed on the side wall of the turntable near the limiting plate, arranged in a circular array about the axis of the transmission shaft. The length direction of the limiting posts is consistent with the axis of the transmission shaft. The end of the limiting post away from the turntable is smoothed. Several slots are opened on the side wall of the limiting plate near the turntable, and the slots correspond one-to-one with the limiting posts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting baffle one, the plastic cups are effectively prevented from being blown out of the collection box when they are blown out of the mold by compressed air. Baffle one is fixed at both ends of the top of the collection box along its width direction, forming a physical barrier to ensure that the plastic cups always remain in the collection box. Baffle two is used to cushion the plastic cups, reducing the damage caused by the plastic cups to the transport equipment by direct impact. Baffle two can be adjusted in posture through the linkage of the scissor lift and the drive mechanism to receive the plastic cups blown out of the mold in a gentler way.

[0016] 2. The drive mechanism can not only adjust the posture of the second baffle, but also drive the entire shell and interception mechanism to rotate synchronously. This can further assist in straightening the plastic cups that fall into the collection box, so that they are arranged more neatly on the transport equipment, which is convenient for subsequent stacking and packaging operations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a conveyor for producing plastic cups with protective functions: it includes a blow molding machine 10 and a collection box 12 disposed on one side of the blow molding machine 10. Both ends of the top of the collection box 12 along its width direction are fixed with baffles 11. The top of the two inner walls of the collection box 12 along its width direction are provided with the same transport device 13. A common housing 20 is rotatably connected to the side wall of the two baffles 11 that are close to each other. The length direction of the housing 20 is consistent with the width direction of the collection box 12. The housing 20 has a hollow structure. An interception mechanism is provided on the side of the housing 20 away from the transport device 13. The interception mechanism includes:

[0027] Several baffles 21 are provided, which are rotatably set on the side of the housing 20 away from the transport equipment 13 and are evenly distributed along the length of the housing 20. Each baffle 21 has a fixed shaft at the center of the side wall near the housing 20, and the fixed shaft passes through the housing 20 and is set inside the housing 20.

[0028] The scissor lift 22 is disposed inside the housing 20, and its extension direction is consistent with the length direction of the housing 20. The scissor lift 22 includes several scissor arm assemblies, and several fixed shafts correspond one-to-one with the several scissor arm assemblies. The fixed shafts are coaxially fixed to the middle of the scissor arm assemblies.

[0029] The annular toothed disc 23 is coaxially fixed to the middle of the scissor arm assembly at one end of the scissor fork frame 22, near the side of the transport equipment 13. The annular toothed disc 23 is meshed with a bevel gear 24 on the side away from the center of the housing 20. A drive mechanism is fixed on the side of the bevel gear 24 away from the center of the housing 20. The drive mechanism is located outside the baffle 11.

[0030] The scissor lift 22 includes several scissor arm groups, each including a scissor arm 1 and a scissor arm 2 that are rotatably connected to each other. The ends of scissor arms 1 and scissor arms 2 that are not in the same group in two adjacent scissor arm groups are rotatably connected to each other. A fixed shaft is fixed at the rotatable connection point between scissor arms 1 and scissor arms 2 in the scissor arm group.

[0031] In the scissor lift 22, the scissor arm assemblies of scissor arm one and scissor arm two are coaxially rotatably connected to pulley one 25 on the side away from the transport equipment 13 at the rotatable connection points. The scissor arm assemblies of two adjacent scissor arm assemblies are coaxially rotatably connected to pulley two 27 on the side away from the transport equipment 13 and the end away from the blow molding equipment 10 at the rotatable connection points. The pulley two 27 is fitted with the same belt 26 in the groove of the pulley one 25 on both sides. The grooves of two adjacent pulley two 27 are not at the same horizontal height.

[0032] It should be noted that: when the blow molding equipment 10 is in operation, it continuously produces plastic cups. The blow molding equipment 10 is also equipped with a compressed air ejection device to blow out the produced plastic cups, which will not be described in detail here.

[0033] Baffle 11 is fixed at both ends of the top of the collection box 12 to form a physical barrier to prevent the plastic cup from being blown out of the collection box 12. In the initial state, the length direction of baffle 21 is consistent with the width direction of the collection box 12, ready to receive the plastic cup blown out from the blow molding equipment 10. The side wall of baffle 21 is provided with flexible material to absorb the impact of the plastic cup.

[0034] The scissor lift 22 includes several sets of scissor arms. Each set of scissor arms includes two scissor arms, 1 and 2, which are rotatably connected to each other. Scissor arms 1 and 2 within the same set are stacked on top of each other and are rotatably connected to each other at the middle by the same damping shaft 1. Scissor arms 1 and 2 between adjacent sets of scissor arms are rotatably connected to each other by the same damping shaft 2. Thus, multiple sets of scissor arms are rotatably connected to each other to form a mesh structure. Pulley 1 25 is fixed on damping shaft 1, and pulley 27 is fixed on damping shaft 2 on the side away from the blow molding equipment 10. Both pulley 1 25 and pulley 27 are located on the side away from the transport equipment 13.

[0035] Pulley 25 is a double-groove pulley, and pulley 27 is a single-groove pulley. The grooves of two adjacent pulleys 27 are not at the same horizontal height to avoid mutual obstruction of belts 26. When the drive mechanism drives the bevel gear 24 to rotate, the bevel gear 24 meshes with the ring gear disk 23 to rotate, and then drives all the baffles 21 to rotate synchronously through multiple sets of pulleys 25 and pulleys 27.

[0036] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: one end of the housing 20 is provided through the baffle 11 on that side, and the end of the housing 20 through the baffle 11 is provided with a driving mechanism. The driving mechanism includes a transmission shaft 35 coaxially fixed on the bevel gear 24. The axial direction of the transmission shaft 35 is parallel to the axial direction of the housing 20. The end of the transmission shaft 35 away from the bevel gear 24 is provided through the housing 20. A limiting disk 36 is fixed on the side wall of the housing 20 through the baffle 11. The limiting disk 36 is sleeved on the outside of the transmission shaft 35.

[0037] A motor 30 is fixed to one end of the drive shaft 35 away from the bevel gear 24. A support plate 14 is fixed to the bottom of the motor 30. A cylinder 31 is fixed to the top of the motor 30. A limit plate 32 is fixed to the output end of the cylinder 31. The longitudinal section of the limit plate 32 along the axial direction of the drive shaft 35 is "door" shaped. The notch of the limit plate 32 is set facing the drive shaft 35. A turntable 33 is sleeved on the outer arc wall of the drive shaft 35 corresponding to the notch of the limit plate 32.

[0038] The turntable 33 is located between the motor 30 and the limiting plate 36. A spline sleeve is fixed on the inner arc wall of the turntable 33. A spline is fixed on the outer arc wall of the transmission shaft 35 at a position corresponding to the turntable 33. Several limiting posts 34 are fixed on the side wall of the turntable 33 near the limiting plate 36, arranged in a circular array about the axis of the transmission shaft 35. The length direction of the limiting posts 34 is consistent with the axis of the transmission shaft 35. The end of the limiting post 34 away from the turntable 33 is smoothed. Several slots are opened on the side wall of the limiting plate 36 near the turntable 33, and the slots correspond one-to-one with the limiting posts 34.

[0039] It should be noted that when the cylinder 31 pushes the limiting plate 32 and drives the turntable 33 to slide, the limiting post 34 will move toward the housing 20. When the limiting post 34 is inserted into the slot, the housing 20 will rotate synchronously with the turntable 33. The turntable 33 will rotate synchronously with the transmission shaft 35 under the action of the spline sleeve. This means that at this time, the ring gear 23 and the bevel gear 24 will both rotate around the axis of the transmission shaft 35. That is, at this time, the ring gear 23 and the bevel gear 24 will not rotate relative to each other.

[0040] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides a technical solution: the transport equipment 13 includes multiple sets of conveyor belts evenly distributed along the width direction of the collection box 12, each set of conveyor belts includes two parallel conveyor belts, the distance between the two conveyor belts is slightly greater than the width of the baffle 21, and the distance between two adjacent sets of conveyor belts matches the size of the product to be produced.

[0041] It should be noted that: since common plastic cups have a structure that is wider at the top and narrower at the bottom, which is similar to a frustum structure, the spacing between adjacent conveyor belt groups is sufficient to intercept the plastic cups and prevent them from falling. The collection box 12 is used to collect some defective products that have failed to be molded. The spacing between two adjacent conveyor belts is sufficient for the baffle 21 to pass through. When the drive mechanism drives the baffle 21 to rotate until the length direction of the baffle 21 is perpendicular to the width direction of the collection box 12, the drive mechanism drives the housing 20 and the baffle 21 and the interception mechanism to rotate synchronously. The baffle 21 passes between two adjacent conveyor belts. With continuous rotation, the baffle 21 can move the plastic cups between the housing 20 and the blow molding equipment 10 that have not fallen between the two adjacent conveyor belt groups, thereby making auxiliary adjustments.

[0042] Working principle:

[0043] Baffle 11 is fixed at both ends of the top of the collection box 12 to form a physical barrier to prevent the plastic cup from being blown out of the collection box 12. In the initial state, the length direction of baffle 21 is consistent with the width direction of the collection box 12, ready to receive the plastic cup blown out from the blow molding equipment 10. The side wall of baffle 21 is provided with flexible material to absorb the impact of the plastic cup.

[0044] When the drive mechanism drives the bevel gear 24 to rotate, the bevel gear 24 meshes with the ring gear disk 23 to rotate, which in turn drives all the baffles 21 to rotate synchronously through multiple sets of pulleys 25 and 27. When the drive mechanism drives the baffles 21 to rotate until the length direction of the baffles 21 is perpendicular to the width direction of the collection box 12, the drive mechanism drives the housing 20 and the baffles 21 and the interception mechanism on it to rotate synchronously. The baffles 21 pass between two adjacent conveyor belts. With continuous rotation, the baffles 21 can move the plastic cups between the housing 20 and the blow molding equipment 10 that have not fallen between the two adjacent conveyor belt sets, thereby making auxiliary adjustments.
