Description

Technical Field

[0001] The utility model belongs to the field of PET cold drink cup packaging, in particular to a PET cold drink cup packaging transmission platform. Background Art

[0002] As the name suggests, cold drink cups are specially designed for cold drinks. To ensure safety and hygiene during transportation and storage, and to facilitate subsequent sales, once the cold drink cups are produced, they need to be placed in packaging boxes. Prior to this, a PET cold drink cup packaging conveyor transports the boxes one by one in an orderly manner to the packaging station. Once the boxes are delivered to the packaging station, the cold drink cups are then placed in the boxes.

[0003] Existing PET cold drink cup packaging conveyors typically consist of a platform equipped with two pairs of conveyor wheels, each with a matching conveyor belt between them. A drive motor is also installed on the platform to drive one of the wheels in the pair, creating a conveyor zone between the two conveyor belts. To convey a box, the PET cold drink cup packaging conveyor first places an empty box between the two belts, which clamp the box. Then, when the two drive motors operate simultaneously, the belts rotate, conveying the box.

[0004] Although this method can also complete the conveying of packaging boxes, one drive motor can only drive one belt to rotate, making the overall structure more complicated. In addition, the distance between the two belts cannot be adjusted according to the size of the packaging boxes, and the adaptability is poor. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide a PET cold drink cup packaging and conveying platform, aiming to solve the problems of the existing PET cold drink cup packaging and conveying platform having a relatively complex overall structure and poor adaptability.

[0006] The utility model adopts the following technical solutions:

[0007] The cold drink cup packaging transmission platform includes a carrier, a plurality of conveying rollers are rotatably provided at the front end of the carrier, and a conveying mechanism is provided on both sides of the carrier. The conveying mechanism includes a slide, a pair of front and rear conveying wheels are rotatably provided in the slide, and a matching conveyor belt is sleeved between the same pair of conveying wheels. The shafts of the two conveying wheels at the rear are inserted into the carrier and are respectively provided with double-layer pulleys and pulleys. A pair of upper and lower mounting plates are provided in the carrier, and a pair of sliders and a pair of reversing wheels are respectively provided between the two mounting plates, wherein the sliders are slidably installed and the reversing wheels are rotatably installed, an adjusting wheel is rotatably provided in the slider, a pair of pulling blocks are provided in the carrier, and a tension spring is provided between the pulling block and the slider on the same side, and a linkage belt is commonly sleeved on the adjusting wheel, reversing wheel, pulley and double-layer pulley, and a driving mechanism for driving the double-layer pulley to rotate is also provided on the carrier.

[0008] Furthermore, the driving mechanism includes a fixed frame, an elastic wheel is provided in the fixed frame, a driving motor is provided on the fixed frame, a driving shaft of the driving motor is inserted into the fixed frame and is provided with a driving wheel, a driving belt is sleeved between the driving wheel and the other pulley in the double-layer pulley, and the elastic wheel is located on the outside of the driving belt and always contacts the driving belt.

[0009] Furthermore, a pair of guide grooves are opened on the lower mounting plate, and the shaft is located in the guide grooves on the same side.

[0010] Furthermore, a pair of sliding rods are provided in the carrier, and the slide is slidably installed on the sliding rods through sliding sleeves. Threaded holes are provided on the two sliding sleeves at the same end. An adjusting rod is also rotatably provided on the carrier, and threaded sections in opposite directions are formed at both ends of the adjusting rod, and the adjusting rod passes through the threaded holes.

[0011] Furthermore, a rotating disk is provided at the end of the adjusting rod.

[0012] The beneficial effect of the present utility model is that a pair of conveying mechanisms are provided on the carrier, and a feeding interval is formed between the two conveying mechanisms. When a packaging box is to be transported, the suction cup first absorbs the packaging box and sends the packaging box to the feeding interval. When the packaging box is sent to the feeding interval, the two conveyor belts clamp the packaging box. Driven by the driving mechanism, the two conveyor belts rotate simultaneously and drive the packaging box to move backward until the packaging box moves to the packaging station.

[0017] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not intended to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0019] For the sake of convenience, only the parts related to the embodiments of the present invention are shown.

[0020] Combine Figure 1-4 As shown, the cold drink cup packaging conveying platform includes a carrier 1, and a plurality of conveying rollers 2 are rotatably provided at the front end of the carrier 1. Conveying mechanisms are provided on both sides of the carrier 1, and the conveying mechanisms include a slide 3. A pair of front and rear conveying wheels 4 are rotatably provided in the slide 3, and a matching conveyor belt 5 is sleeved between the same pair of conveying wheels 4. The shafts 6 of the two conveying wheels at the rear are inserted into the carrier 1 and are respectively provided with a double-layer pulley 7 and a pulley 8. A pair of upper and lower mounting plates are provided in the carrier 1, wherein the upper mounting plate is marked as 91 and the lower upper mounting plate is marked as 92. A pair of sliders 10 and a pair of reversing wheels 11 are respectively provided between the two mounting plates, wherein the slider 10 is slidably installed and the reversing wheel 11 is rotatably installed. An adjusting wheel 12 is rotatably provided in the slider 10, and a pair of pulling blocks 13 are provided in the carrier 1. A tension spring 14 is provided between the pulling block 13 and the slider 10 on the same side. A linkage belt 15 is commonly provided on the adjusting wheel 12, the reversing wheel 11, the pulley 8, and the double-layer pulley 7. A driving mechanism for driving the double-layer pulley 7 to rotate is also provided on the carrier 1.

[0021] After the cold drink cups are produced, they need to be placed in packaging boxes. Before this, a PET cold drink cup packaging conveyor can be used to transport the packaging boxes one by one in an orderly manner to the packaging station. Once the packaging boxes are transported to the packaging station, the cold drink cups can be placed in the packaging boxes.

[0022] In this structure, a pair of conveyor mechanisms are mounted on the carrier, with a feed zone formed between them. When using this PET cold drink cup packaging conveyor to transport a box, a suction cup is first used to hold the box and transport it to the feed zone. Once there, the two conveyor belts clamp the box. Subsequently, the drive mechanism drives the two conveyor belts to rotate simultaneously, moving the box backward until it reaches the packaging station. Since the box is constantly clamped by the two conveyor belts during transport, it maintains greater stability throughout the entire transport process.

[0023] When the driving mechanism drives the double-layer pulley to rotate, the pulley rotates synchronously with the double-layer pulley under the drive of the linkage belt, so the double-layer pulley and the two conveying wheels connected by the shaft rod also rotate synchronously, so that the two conveyor belts rotate synchronously, and the packaging box moves backward under the conveyance of the conveyor belt.

[0024] As a preferred structure, Figure 4 The platform 1 is provided with a pair of slide bars 16. The carriage 3 is slidably mounted on the slide bars 16 via slide sleeves 17. The two slide sleeves 17 at the front end each have threaded holes. An adjustment rod 19 is also rotatably mounted on the front end of the platform 1. The ends of the adjustment rod 19 are located in threaded holes on the same side, and threaded sections are formed at both ends of the adjustment rod 19 in opposite directions. A rotating disk 20 is also provided at the end of the adjustment rod 19.

[0025] In this structure, the distance between the two conveyor mechanisms can be adjusted to change the size of the feed zone to accommodate packages of varying sizes. This allows the PET cold drink cup packaging conveyor to transport packages of varying sizes. To adjust the feed zone, first place the current package onto the conveyor rollers and then rotate the rotating disk clockwise. Due to the two oppositely threaded sections on the adjustment rod, the clockwise rotation of the rotating disk causes the two sleeves at the front to move toward each other, and the two carriages to move a short distance toward each other until the two conveyor belts can barely grip the current package. The current package is smaller than the previous one.

[0026] In this PET cold drink cup packaging conveyor, Figure 2The driving mechanism includes a fixed frame 21, an elastic pulley 22 is provided in the fixed frame 21, and a driving motor 23 is provided on the fixed frame 21. The driving shaft of the driving motor 23 penetrates into the fixed frame 21 and is provided with a driving pulley 24. A driving belt 25 is sleeved between the driving pulley 24 and the other pulley of the double-layer pulley 7, and the elastic pulley 22 is located on the outside of the driving belt and always contacts the driving belt 25. When the driving mechanism is used to drive the double-layer pulley to rotate, the driving motor first drives the driving pulley to rotate, and the double-layer pulley rotates under the linkage of the driving belt.

[0027] In the above situation, if both conveyor mechanisms move inward, the carriages move inward during this process, and the two rear conveyor wheels also move synchronously toward each other. As the double-layer pulleys and pulleys move toward each other, the linkage belt tends to loosen. Simultaneously, under the tension of the tension spring, the slider drives the adjustment wheel outward. Under the adjustment of the adjustment wheel, the tension of the linkage belt remains essentially constant. Thus, when the two carriages move laterally, the linkage belt remains straightened under the adjustment of the adjustment wheel, without affecting the rotation of the two rear conveyor wheels.

[0028] In addition, when the double pulley moves inward, the double pulley drives the drive belt to move a short distance, and in this process the drive belt pushes the elastic wheel to move a short distance outward. Under the elastic resistance of the elastic wheel, the drive belt is also in a straight state.

[0029] Since the elastic wheel is limited to the existing technology, it is of course a preferred structure, such as Figure 2 A guide groove 26 is formed in the fixed frame 21, and the elastic wheel 22 is slidably mounted in the guide groove 26. A spring 27 is fixed in the guide groove 26, and the other end of the spring 27 is fixed to the corresponding position of the elastic wheel 22. When the double-layer pulley moves inward, the drive belt pushes the elastic wheel to slide outward in the guide groove. At this time, the spring is compressed, and under the pre-load of the spring, the elastic wheel and the drive belt come into contact. When the double-layer pulley moves outward, the spring recovers its deformation, and the elastic wheel and the drive belt come into contact again. Under the action of the elastic wheel, whether the two slides move inward or outward at the same time, the drive belt is always in a straight state, thereby not affecting the rotation of the two conveyor belts.

[0030] In addition, if Figure 3 The lower mounting plate 92 is provided with a pair of guide slots 28, with the shaft 6 positioned within the guide slots on the same side. In this structure, the carriage also has chute slots identical to the guide slots, with the upper and lower ends of the shaft positioned within the chute slots and guide slots, respectively. These chute slots not only guide the shaft but also serve to limit its position.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
