Whether in coffee shops, fast food restaurants, or by the water dispenser at the office, paper cups are ubiquitous. This has led to a continuous increase in market demand for paper cups, prompting paper cup manufacturers to seek more efficient and stable production equipment to improve production efficiency, reduce costs, and meet the massive market demand. As a key piece of equipment in paper cup production, paper cup base forming machines have also undergone continuous development and improvement within this context.

[0003] When the paper tape is being conveyed and cut, if the paper tape is wrinkled, the cutting part will be offset, resulting in uneven cutting and irregular shape of the cup bottom. Summary of the Invention

The connecting frame drives the rotating shaft to rotate, and then the rotating sleeve on the inner round rod of the connecting frame drives the rotating rods on both sides to rotate. The grabbing grooves opened on both sides of the rotating rod can grab and collect flocculent dust impurities that follow waste paper scraps into the collection box from the outside, realize automatic collection of dust impurities, further improve the collection effect, and avoid dust impurities flying in the collection box or accumulating in other places, which helps to improve product quality and reduce dust pollution to equipment and products.

[0005] The present invention provides a paper cup bottom forming machine for paper cup production. It has the following beneficial effects: 1. The paper cup bottom forming machine for this paper cup production is equipped with a guide mechanism. The guide wheel contacts the bottom of the paper tape and guides the cutting position to be flat. This can keep the paper tape flat and accurately positioned during the cutting process, avoiding problems such as uneven cutting and irregular cup bottom shape caused by wrinkles or position deviation of the paper tape, thereby improving the forming quality and dimensional accuracy of the cup bottom and reducing the scrap rate.

[0006] 2. The paper cup bottom forming machine for paper cup production is equipped with a winding component. The cooperation between the extrusion mechanism and the second spring realizes an adaptive adjustment mechanism.

When the waste paper tape is being wound up, the squeezing mechanism 56 contacts the waste paper tape wound up on the winding drum 52, thereby preventing the paper tape from being wound unevenly or deviating. When the squeezing force is greater than the tensile force of the second spring 55, the second spring 55 drives the squeezing mechanism 56 to move via the limiting shaft 54, thereby preventing the squeezing force from interfering with the winding rotation of the winding drum 52, thereby avoiding damage to the equipment caused by the squeezing force, and also protecting the paper tape from being damaged due to excessive squeezing. See also Figure 1-Figure 7The extrusion mechanism 56 includes an extrusion frame 561, both sides of the extrusion frame 561 are fixedly connected with connecting blocks 562, the side of the connecting block 562 away from the extrusion frame 561 is fixedly connected to the side of the sliding block 53, the extrusion frame 561 is rotatably connected with a roller 563, the inner side of the roller 563 is slidably connected with a slide rod 564, the side of the slide rod 564 is fixedly connected with a stopper 565, the other end of the slide rod 564 away from the roller 563 is fixedly connected to an extrusion roller 567, both sides of the extrusion roller 567 are fixedly connected with an arc plate 568, and a third spring 566 is sleeved on the slide rod 564, one end of the third spring 566 is fixedly connected to the side of the stopper 565, and the other end of the third spring 566 is fixedly connected to the inner side of the roller 563; When the squeezing frame 561 drives the roller 563 to contact the waste paper tape roll wound on the winding drum 52, the roller 563 is squeezed and contacted with the waste paper tape roll wound on the winding drum 52, which can ensure the flatness and tightness of the winding, making the wound waste paper tape roll more regular, convenient for subsequent processing or storage, and also helping to improve the space utilization rate of the winding drum 52; Arc plates 568 are provided on both sides of the squeezing roller 567 to better control the friction when the roller 563 contacts and rolls with the waste paper roll, making the friction applied to the waste paper roll more uniform during the winding process, further improving the smoothness of the winding and avoiding problems such as deviation of the paper roll or loose winding caused by uneven friction.

At the same time, the suction force of the suction machine 33 causes the rotating mechanism 35 to rotate on the top of the baffle 34, effectively preventing the paper scraps from flying around, keeping the work area clean and tidy, and reducing the cleaning workload. See also Figures 1-9The rotating mechanism 35 includes a rotating shaft 351, and a rotating frame 352 is fixedly connected to the upper and lower sides of the rotating shaft 351.

[0013] Specific workflow: Install the paper tape roll that meets the requirements on the paper unwinding roller of the unwinding component 6, and ensure that the tension of the paper tape is moderate to ensure smooth feeding; The unwinding component 6 is started, and the motor drives the paper unwinding roller to rotate, and the paper tape is intermittently delivered to the cutting component 4 according to the set length; When the paper tape is conveyed to the cutting component 4, the paper tape is punched out to form a circular cup bottom blank; When the paper tape on the unwinding component 6 is being punched, the collecting component 3 is opened at the same time to collect the cut scraps; The cut paper strip is guided to the reeling component 5 to reel in the cut waste. The blanked cup base is transferred to the working position of the curling mechanism in the forming part 2 by means of a clamp. During the transfer process, the position and posture of the cup base are precisely adjusted to ensure the accuracy of the fit with the curling die. The die of the curling mechanism starts working, and through rotation and extrusion, the edge of the cup base is curled into a specific shape to form the curled edge of the cup base. After the curling is completed, the heating mechanism of the heat sealing mechanism in the forming component 2 will start quickly to heat the heat sealing mold to the preset temperature. The temperature control system will accurately control the heating temperature to ensure the consistency of the heat sealing effect. The bottom of the cup is sent between the heat sealing molds. Under the action of pressure, the heat sealing mold will fit the edge of the cup bottom tightly to the cup body and maintain it for a certain period of time so that the cup bottom material will be hot-melted at high temperature to achieve a firm seal between the cup bottom and the cup body.
