Description

Technical Field

[0001] This utility model relates to the field of paper cup machine technology, specifically a high-speed paper cup machine. Background Technology

[0002] A paper cup machine is a type of paper container made by mechanically processing and bonding base paper (white cardboard) made from chemical wood pulp. It is shaped like a cup and can be used for frozen food and hot drinks. It is safe, hygienic, lightweight and convenient, making it an ideal piece of equipment for public places, hotels and restaurants.

[0003] According to CN107756871A, a paper tube forming mechanism is disclosed. This technology discloses a paper tube forming mechanism, including a forming mold, a demolding device, and an auxiliary forming device. The demolding device includes a demolding head for demolding, which is connected to a demolding transmission device. The demolding head is driven by the demolding transmission device to move the paper tube on the forming mold forward into the auxiliary forming device. The auxiliary forming device includes a core support and a top support. The core support is located in front of the forming mold and is connected to the forming mold for the paper tube to pass through. Rollers and / or belts are provided on opposite sides of the core support and the top support. The rollers or belts on the core support and / or the top support are connected to a drive device. This technology has the technical effect of "applying pressure to enclose the connection when clamping the paper tube, thereby improving the roundness of the paper tube".

[0004] During the cup bottom processing of a paper cup machine, the paper feeding mechanism is responsible for precisely feeding the paper from the roll into the cutting station, where it is then accurately cut according to the preset cup bottom size and shape, producing individual cup bottom paper pieces. However, when the roll of paper runs out, it must be replaced promptly. In this process, the secure fixing of the roll to the paper is particularly important, with common fixing methods including clips and screws. While clip fixing is convenient in some situations, its stability may be insufficient in the high-speed environment of a paper cup machine. Prolonged mechanical vibration and continuous operation can easily loosen the clips, affecting the stable transmission of the roll. In contrast, while screw fixing is more secure, it requires removing and installing one or more screws, which undoubtedly increases the complexity and time-consuming nature of changing the roll, reducing production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-speed paper cup machine. The roll assembly facilitates the disassembly and replacement of the paper roll while ensuring the secure fixing of the paper roll, thus providing a strong guarantee for the stable operation and efficient output of the paper cup machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed paper cup machine, comprising a machine body, on which a cup body feeding rack, a feeding mechanism, a heating mechanism, a bonding mechanism, and a discharging mechanism are arranged sequentially from left to right. The machine body also includes a cup bottom processing mechanism for processing the cup bottoms during the paper cup production process. The cup bottom processing mechanism includes:

[0007] The lifting assembly includes a base fixed to the front right side of the machine body, a cylinder mounted on the base, and a mounting bracket fixed to the output end of the cylinder;

[0008] The drum assembly includes a drum seat fixed to the front end of the mounting frame. Several equally spaced shaft seats are fixed to the outer edge of the front end of the drum seat. A bracket is pivotally connected to the inner side of the front end of the shaft seat. A support frame is pivotally connected to the outer end of the bracket. A support plate is installed on the outer wall of the support frame. A parallel frame is pivotally connected to the outer side of the front end of the shaft seat, and another one is pivotally connected to the support frame. A bolt is threaded in the center of the front end of the drum seat. A triangular frame is rotatably installed on the outside of the bolt, and the end of the triangular frame is pivotally connected to the inner end of the bracket.

[0009] The shearing assembly is mounted on the machine body and is used for shearing and shaping the bottom of the cup.

[0010] Preferably, the shearing assembly includes an upper fixed plate mounted on the machine body, guide rods fixed at the four corners of the top of the upper fixed plate, a lower fixed plate fixed between the tops of the four guide rods, a movable plate slidably mounted between the upper fixed plate and the guide rods via the lower fixed plate, an upper cutter head and a lower cutter head fixed at the lower end of the lower fixed plate and the upper end of the movable plate respectively, a fixed seat fixed at the bottom of the upper fixed plate, a top rod slidably mounted through the fixed seat and connected at its upper end to the movable plate.

[0015] Beneficial effects

[0016] This invention provides a high-speed paper cup machine. Compared with the prior art, it has the following advantages:

[0017] 1. After the paper roll used for processing the bottom of the cup is installed on the roll assembly, the tripod moves horizontally by rotating the bolt. The end of the tripod slides along the inside of the waist-shaped hole and drives the bracket to rotate through the waist-shaped hole. With the cooperation of the parallel frame, the bracket drives the support plate on the support frame to open outward, thereby fixing the paper roll. Similarly, when the paper roll is used up, it can be disassembled by simply rotating the bolt.

[0018] 2. The paper is fed to the cutting assembly via the first and second paper pre-feeding components, and is located between the lower fixed plate and the movable plate. The drive device controls the top rod to work with the movable plate to drive the lower cutter head and the upper cutter head to cut out the circular paper cup bottom from the paper roll between them, and then feed it into the bonding mechanism. When the movable plate drives the lower cutter head and the upper cutter head to cut out the circular paper cup bottom, the movable plate also drives the lower cutter head and the upper cutter head to cut off the waste paper remaining from the previous cutting. The cut waste paper falls into the waste discharge port at the bottom of the cup and is then conveyed away.

[0019] 3. After one end of the roll paper is fed between the lower fixed plate and the movable plate, it is positioned by the baffle. In addition, the side plate reduces the entry of external heat sources to prevent the roll paper from sticking due to high temperature. Attached Figure Description

[0028] The drum assembly 22 includes a drum seat 221 fixed to the front end of the mounting frame 215. A plurality of equally spaced shaft seats 222 are fixed to the outer edge of the front end of the drum seat 221. A bracket 223 is pivotally connected to the inner side of the front end of the shaft seat 222. A support frame 224 is pivotally connected to the outer end of the bracket 223. A support plate 225 is installed on the outer wall of the support frame 224. A parallel frame 226 is pivotally connected to the outer side of the front end of the shaft seat 222, and another one is pivotally connected to the support frame 224. A bolt 227 is threadedly installed at the center of the front end of the drum seat 221. A tripod 228 is rotatably installed on the outside of the bolt 227, and the end of the tripod 228 is pivotally connected to the inner end of the bracket 223.

[0029] The shearing component 23 is mounted on the machine body 1 and is used for shearing and shaping the bottom of the cup.

[0030] In this embodiment, after the roll of paper used for processing the bottom of the cup is installed on the roll assembly 22, the tripod 228 is moved horizontally by rotating the bolt 227. The end of the tripod 228 slides along the inside of the waist-shaped hole 229 and drives the bracket 223 to rotate through the waist-shaped hole 229. With the cooperation of the parallel frame 226, the bracket 223 drives the support plate 225 on the support frame 224 to be pushed outward, thereby fixing the roll of paper. Similarly, when the roll of paper is used up and disassembled, only the bolt 227 needs to be rotated.

[0031] Specifically, the shearing assembly 23 includes an upper fixed plate 231 mounted on the machine body 1. Guide rods 232 are fixed at the four corners of the top of the upper fixed plate 231.

[0032] In this embodiment, after one end of the paper roll is fed into the cutting assembly 23, it is located between the lower fixed plate 233 and the movable plate 234. The drive device controls the top rod 238 to cooperate with the movable plate 234 to drive the lower cutter head 236 to cooperate with the upper cutter head 235 to cut out the circular paper cup bottom from the paper roll between them.

[0033] Specifically, the shearing assembly 23 also includes an upper cutter 239 fixed to the right end of the lower fixed plate 233, and a lower cutter 2310 fixed to the right end of the movable plate 234.

[0034] In this embodiment, when the movable plate 234 drives the lower cutter head 236 to cooperate with the upper cutter head 235 to cut out the circular bottom of the paper cup, the movable plate 234 also drives the lower cutter 2310 to cooperate with the upper cutter 239 to cut off the waste paper remaining from the previous cut, and the cut waste paper falls into the waste discharge port 26 at the bottom of the cup and is transported away.

[0035] Specifically, the shearing assembly 23 also includes a baffle 2311 fixed to the outer wall of the lower cutter 2310, and side plates 2312 are fixed to the outer walls of both ends of the lower fixing plate 233.

[0038] In this embodiment, the output end of the cylinder 216 drives the mounting bracket 215 to adjust the height of the paper roll mounted on the shearing assembly 23.

[0039] Specifically, the cup bottom processing mechanism 2 also includes a first roll paper pre-feeding component 24 located at the front end of the upper part of the machine body 1, a second roll paper pre-feeding component 25 located on the top of the machine body 1 and to the left of the shearing component 23, and a cup bottom waste discharge port 26 fixed on the machine body 1 and located to the right of the shearing component 23.

[0040] In this embodiment, after the roll of paper used for processing the bottom of the cup is installed on the roll assembly 22, it is transported to the shearing assembly 23 for shearing by the first roll paper pre-feeding assembly 24 in conjunction with the second roll paper pre-feeding assembly 25.

With the cooperation of the parallel frame 226, the bracket 223 drives the support plate 225 on the support frame 224 to be pushed outward, thereby fixing the roll paper.

[0042] Then, the paper is fed to the cutting assembly 23 by the first paper pre-feeding assembly 24 and the second paper pre-feeding assembly 25, and is located between the lower fixed plate 233 and the movable plate 234. The drive device controls the top rod 238 to work with the movable plate 234 to drive the lower cutter head 236 to work with the upper cutter head 235 to cut out the circular paper cup bottom from the paper roll between them, and send it into the bonding mechanism 6.

[0043] Furthermore, when the movable plate 234 drives the lower cutter head 236 to cooperate with the upper cutter head 235 to cut out the circular bottom of the paper cup, the movable plate 234 also drives the lower cutter 2310 to cooperate with the upper cutter 239 to cut off the waste paper left over from the previous cut, and the cut waste paper falls into the waste discharge port 26 at the bottom of the cup and is conveyed away.

[0044] Meanwhile, the paper cup body is fed into the machine body 1 through the cup body feeding rack 3, and then fed into the heating mechanism 5 through the feeding mechanism 4 to heat the PE film on the local surface. Then it is fed into the bonding mechanism 6 for bonding of the bottom of the paper cup. After bonding, it is fed out through the unloading mechanism 7.
