Description

Technical Field

[0001] The present invention relates to the technical field of paper cup production, and particularly to a fully servo-driven paper cup machine. Background Art

[0002] The base paper is subjected to single-sided or double-sided PE coating through a coating machine to obtain coated paper, which has properties such as waterproof, oil-proof, and heat-sealable, and thus is applied in the production of paper cups. During the production of paper cups, it is necessary to bond the cup barrel and the cup bottom. When ultrasonic welding is used for bonding, mechanical pressure is generated between material molecules due to mechanical vibration, and heat is released to soften and bond the PE film in the paper.

[0003] In the prior art, a paper cup machine can achieve automated production and includes a paper feeding component, a cup barrel bonding component, a barrel hooking component, and a forming turntable component. The paper feeding component sequentially sends the coated paper under the welding seat of the cup barrel bonding component; the cup barrel bonding component winds the cut coated paper around the welding seat to form a columnar or conical cup barrel for scarfed bonding; the barrel hooking component removes the welded cup barrel from the welding seat and sends it to the next process; the forming turntable component sequentially receives the cup barrel, preheats it, and then welds and bonds it with the cup bottom.

[0004] The defective products generated in the production of paper cups include insufficient welding, bonding misalignment, etc. Among them, the bonding of the cup barrel is the first process of welding. Once the cup barrels overlap and are misaligned, it will not only cause bonding misalignment, but also affect the welding of the cup bottom, resulting in problems such as paper cup deformation. Therefore, the welding stability of the cup barrel is particularly important for the production qualification rate of paper cups. It should be noted that when the cup barrel is welded, the coated paper is under the welding seat. When the paper cup is bent directly by clamping with welding jaws, the probability of paper cup misalignment is also increased. Especially when welding a conical paper cup, the coated paper not only bends but also tilts. While studying to improve the production efficiency of the paper cup machine, we are also working hard to improve the production qualification rate. Therefore, a fully servo paper cup machine for improving the welding stability of the cup barrel is designed and provided. Summary of the Invention

Detailed implementation mode

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] The present invention will be further described below with reference to the embodiments.

[0040] Embodiment:

[0041] Please refer to Figure 1-2 , a fully servo-driven paper cup machine, including a paper feeding slide 100, a support seat 200, a welding seat 300, a welding table 400, a fixed connecting piece 600, and a welding clamping component 700;

[0042] The paper feeding slide 100 is used to convey the laminated paper to the cup barrel bonding area;

[0043] The support seat 200 is installed at the end of the paper feeding slide 100, and there is a gap through which the laminated paper passes between the middle of the bottom end of the support seat 200 and the surface of the paper feeding slide 100.

[0044] The welding seat 300 is vertically fixed to the side of the support seat 200 and is used to support the winding and forming and welding fixation of the cup barrel;

[0045] The welding table 400 is arranged above the welding seat 300 to weld the formed cup barrel, and the welding table 400 is equipped with a pioneer component 500 to prevent the cup barrel from winding out of position;

[0046] The welding support components 700 are installed on both sides of the welding seat 300 to allow the unfolded coated paper to bend and wrap around the welding seat 300 to overlap;

[0047] The fixing connecting piece 600 is located below the welding seat 300 and is used to absorb and fix the coated paper so that it is completely and tightly attached to the welding table 400 .

[0048] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0049] See also Figure 1-3 In the embodiment of the present invention, the paper feeding slide 100 includes a paper feeding area and a cup barrel bonding area; a stacking rack and a grabbing component of the coated paper are installed at the end of the paper feeding area, and the grabbing component sequentially grabs the coated paper and places it on the paper feeding slide 100, and transports it to the cup barrel bonding area. Among them, a support seat 200 is installed on the paper feeding slide 100, and there is a gap between the middle part of the bottom end of the support seat 200 and the surface of the paper feeding slide 100 for the coated paper to pass through, and the coated paper enters the cup barrel bonding area after passing through the support seat 200. In the cup barrel bonding area, the paper feeding slide 100 is provided with a rectangular chute, wherein a welding seat 300, a welding table 400, etc. are arranged above the chute, and a fixed connection member 600 and a welding support member 700 are arranged below the chute, and the local structures of the fixed connection member 600 and the welding support member 700 protrude above the paper feeding slide 100 through the chute.

[0050] In the embodiment of the present application, ultrasonic welding is used to weld and bond the laminated paper to form a cup barrel. Specifically, the laminated paper is rolled on the welding seat 300, and the overlapping part of the laminated paper is pressed using the welding table 400. Among them, the welding seat 300 is vertically fixed on the side of the support seat 200, and the welding seat 300 is designed as a cone structure. An inclined or horizontal welding surface 301 is cut on the upper surface of the welding seat 300. During processing, the laminated paper is overlapped on the welding surface 301 for bonding. Bucket hook grooves 302 are symmetrically opened on both sides of the welding seat 300 to facilitate the hook claws or clamps to quickly remove the bonded cup barrel.

[0051] The welding table 400 is suspended above the welding seat 300 by the pneumatic lifting platform 800. The pneumatic lifting platform 800 is an inverted U-shaped structure, fixed on the paper feeding slide 100, and used to control the up and down movement of the welding table 400. The bottom surface of the welding table 400 is parallel to the welding surface 301, and is better attached to the welding surface 301 when pressed down. The ultrasonic welding head 401 is first installed on the bottom surface of the welding table 400, and the pioneer component 500 is installed at a position staggered from the ultrasonic welding head 401. During the welding process, the pioneer component 500 will preferentially contact the coated paper and promote its overlap to avoid misalignment.

[0052] See also Figure 2 ,4 5, where the pioneer component 500 consists of a first spring 501, a support rod 502, an overlapping pressure plate 503, etc.; a plurality of support rods 502 are symmetrically distributed around the ultrasonic welding head 401 and sequentially penetrate through the pneumatic lifting table 800. The upper end of the support rod 502 is connected to the pneumatic lifting table 800 through the first spring 501, and the lower end of the support rod 502 is fixedly connected to the overlapping pressure plate 503. The lengths of the support rods 502 extending downward on both sides of the ultrasonic welding head 401 are different, causing the overlapping pressure plates 503 on both sides to be stratified up and down, facilitating the promotion of the coating paper and promoting its overlap to avoid dislocation. During implementation, when the two welding jaws 701 clamp the wound coating paper and attach it to the welding seat 300, the overlapping coating paper will be stratified up and down, and then the ultrasonic welding head 401 is used for welding and bonding. Since the arc surfaces of the two welding jaws 701 are similar and symmetrically arranged, when the coating paper is wound, its two ends will abut against each other, the ends will be additionally curled, and the up and down stratification will fail. The overlapping pressure plate 503 of the pioneer component 500 is used to promote stratification and avoid welding dislocation. It should be noted that the height difference of the up and down stratification of the overlapping pressure plate 503 can be adjusted during production.

[0053] In some embodiments, the bottom surface of the ultrasonic welding head 401 is flush with the bottom surface of the pneumatic lifting table 800, and the bottom surface of the pneumatic lifting table 800 will be provided with an overlapping pressure plate 503 that can accommodate and hide it.

[0054] In some embodiments, the bottom surface of the ultrasonic welding head 401 protrudes from the lower side of the pneumatic lifting table 800, and the thickness of the ultrasonic welding head 401 protruding upward will be greater than or equal to the thickness of the overlapping pressure plate 503.

[0055] Please refer to Figure 3 、 6 , in the embodiments of the present application, welding clamping components 700 are provided on both sides of the welding seat 300 and partially extend below the paper feeding slide table 100. When the welding clamping components 700 approach and fit the welding seat 300, the unfolded coating paper is bent and wound around the welding seat 300 to generate an overlap. Specifically, the welding clamping component 700 includes welding jaws 701, a base 702, a servo motor 703, a bidirectional lead screw 704, a guide rod 705, etc.; the welding jaws 701 with arc-shaped designs on both sides are distributed on both sides of the welding seat 300, and the base 702 is fixed below the welding jaws 701. The base 702 extends below the paper feeding slide table 100. The two bases 702 below the paper feeding slide table 100 are simultaneously penetrated by the bidirectional lead screw 704 and the guide rod 705. The threads on both sides of the bidirectional lead screw 704 are centrosymmetric. A servo motor 703 is connected to one end of the bidirectional lead screw 704, and the servo motor 703 is used to control the rotation of the bidirectional lead screw 704 to control the simultaneous movement of the two welding jaws 701 in the same or opposite directions. The guide rod 705 is respectively slidably connected to the two bases 702 to prevent the welding jaws 701 from tilting during movement.

[0056] Please refer to Figures 7-10 Figures 7-10 , in the embodiment of the present application, after the coated paper is sent to the chute of the paper feeding slide table 100, it is lifted by the fixed connecting piece 600. The fixed connecting piece 600 and the welding jaw 701 are controlled by the servo motor 703 together. When the welding jaw 701 moves, it will lift the coated paper upward so that it adheres to the welding seat 300.

[0057] Specifically, the fixed connecting piece 600 includes a fixed seat 601, a universal stage 602, a lifting assembly 603, etc.; the fixed seat 601 is arranged below the welding seat 300 to lift the unfolded coated paper; the universal stage 602 is arranged at the bottom of the fixed seat 601 to control the inclination and return of the fixed seat 601; the lifting assembly 603 is installed below the universal stage 602 to control the lifting or lowering of the fixed seat 601 and the universal stage 602 by forward or reverse rotation.

[0058] Among them, the fixed seat 601 is composed of a first platform 604, a support 605, a first rack 606, a coil spring 607, etc.; the first platform 604 is designed as a column and has a cavity 608 opened in the middle. The two supports 605 are symmetrically arranged on both sides of the first platform 604. A suction cup 610 is fixed on the top of the first platform 604, and the top of the suction cup 610 is lower than the top surface of the support 605. After the coated paper enters the cup barrel bonding area, it is first lifted by the two supports 605. In addition, the first rack 606 is fixed to the side of the support 605, and the two first racks 606 are symmetrically centered and penetrate into the cavity 608. A connecting shaft is vertically rotatably connected in the middle of the cavity 608, and a first gear 609 is sleeved on the connecting shaft. The first gear 609 is meshed with the two first racks 606 at the same time, and a coil spring 607 is fixed on the connecting shaft.

[0059] One implementation of the fixed seat 601 is that when the two welding jaws 701 approach each other, the base 702 will squeeze the support 605, causing the two supports 605 to approach each other. During the approaching process, the coated paper is bent and oriented towards the welding jaw 701, facilitating the welding jaw 701 to bend and wind the coated paper around the welding seat 300. When the first rack 606 moves, the first gear 609 and the connecting shaft rotate, causing the coil spring 607 to deform. The elastic force generated by the coil spring 607 can automatically reset the support 605 after the welding jaw 701 is reset. In addition, a rubber pad is fixed to the end of the first rack 606 to avoid oscillation when the support 605 is reset. It should be noted that the above implementation needs to be carried out when the fixed seat 601 is lifted and the middle part of the coated paper is clamped at the bottom of the welding seat 300.

[0060] Among them, the universal stage 602 is composed of a second platform 611, a piston tube 612, a second spring 613, a piston rod 614, etc.; the universal stage 602 is arranged below the first platform 604, which can make the fixing seat 601 tilt under force and can be reset. Specifically, a plurality of piston tubes 612 are evenly distributed and fixed on the second platform 611, the piston rod 614 partially penetrates into the piston tube 612 and is movably connected thereto, the second spring 613 is fixed inside the piston tube 612, and the second spring 613 is connected to the piston rod 614 to lift it, and the top of the piston rod 614 is spherical and penetrates into the first platform 604 and is movably connected thereto. Thus, the first platform 604 can tilt at any angle under force and return to the original position after the force is released.

[0061] In some embodiments, the fixing seat 601 is lifted, the suction cup 610 contacts the coated paper and clamps it under the welding seat 300. Since the welding seat 300 has a conical design with an inclined bottom surface, the entire fixing seat 601 tilts while contacting the welding seat 300. The inclined end is realized by the piston rod 614 retracting into the piston tube 612. During this process, the second spring 613 deforms, and the elastic force of the second spring 613 can control the reset of the fixing seat 601 when it descends. It should be noted that the fixing seat 601 and the universal stage 602 are lifted and lowered synchronously.

[0062] Among them, the lifting assembly 603 is located below the chute and is used to control the synchronous lifting and lowering of the fixing seat 601 and the universal stage 602. However, the lifting assembly 603 is only a power transmission assembly, and it is powered by a servo motor 703 through connection with a bidirectional lead screw 704.

[0063] Specifically, the lifting assembly 603 is composed of a second rack 616, a third gear 617, a second gear 618, a rotating shaft 619, etc. Two rotating shafts 619 are arranged in parallel. One or more third gears 617 are sleeved on one of the rotating shafts 619. A connecting rod fixed to the second platform 611 is fixed on the other rotating shaft 619. Two second gears 618 are provided. One second gear 618 is sleeved on the end of the bidirectional lead screw 704, and the other second gear 618 and the third gear 617 are sleeved on one of the rotating shafts 619 together. The two second gears 618 are meshed and connected. When the servo motor 703 works, one of the rotating shafts 619 can be rotated. One or more brackets 615 are designed between the two rotating shafts 619. The brackets 615 are vertically provided with limit grooves, and the second rack 616 is installed in the limit grooves. The second rack 616 can slide up and down in the limit grooves. In addition, one or more teeth are movably connected to the upper and lower sides of the second rack 616 through a third spring. A fixing rod fixed to the rotating shaft 619 for fixing the connecting rod is fixed on the side of the second rack 616. The rotating shaft 619 is vertically fixed with a connecting rod fixed to the second platform 611. The second rack 616 is connected to the third gear 617, is controlled to slide up and down, and drives the rotating shaft 619 and the connecting rod to move up and down, so as to realize the lifting and lowering of the fixing seat 601.

[0064] It should be mentioned that the teeth are used to mesh with the third gear 617 when the second rack 616 moves to the highest point or the lowest point, so as to avoid hindering the continuous rotation of the bidirectional lead screw 704.

[0065] In the above implementation, the lifting and lowering of the fixing seat 601 occur in the middle process of the movement of the welding jaw 701, and are used to quickly fix the plastic-coated paper on the welding seat 300 and facilitate the clamping of the welding jaw 701.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
