Description

Technical Field

[0001] The utility model relates to the technical field of light industrial machinery, in particular to a device for processing and forming the inner and outer layers of a paper cup. Background Art

[0002] Currently, most paper cups produced by developed paper cup machines are vertical-walled, and these are also used in most situations. These vertical-walled cups are unsuitable for serving hot beverages like tea when entertaining guests, as they pose a risk of burns. Furthermore, current paper cup production equipment only produces a single style of cup, and the molds used are all vertical-walled. This makes it unsuitable for producing cups with curved bodies, such as those found in kung fu tea cups, which have hollow interiors.

[0003] Patent 202111173515.8 discloses a fully automated tea cup production equipment, including a support frame, the top of which is fixedly connected to a storage bin, and an operating table is provided on the inner side of the support frame, the operating table is located directly below the storage bin, the top of the operating table is provided with a first rotating disk and a second rotating disk, the second rotating disk is located above the first rotating disk, the top of the operating table is fixedly connected to a tea cup placement rack, and the upper end surface of the operating table is symmetrically fixedly connected to a filter membrane placement rack, the filter membrane placement racks are distributed on both sides of the second rotating disk. Through the mutual cooperation between the second cylinder and the connecting rod, the tea leaves in the discharge pipe can be directly transported to the bottom of the tea cup when being transported into the tea cup, avoiding the tea leaves from spilling onto the operating table; and through the mutual cooperation between the linkage plate and the film pressing part, the material guide part, the film transfer part and the film pressing part can achieve synchronous movement. However, it still has many shortcomings. For example, the fully automated teacup production equipment has a relatively complex structure, is difficult to operate and keep the work surface clean, and does not change the appearance of the teacup much, except that the tea is added to the cup in advance.

[0004] Patent 202320178160.1 discloses a device for manufacturing paper cups, including a glue supply device, a glue coating device, a paper cup transport device, a weighing device, a glue nozzle cleaning device, and a glue nozzle centering device. The glue supply device is connected to the glue coating device, which is arranged above the paper cup transport device. The paper cup transport device can transport pre-treated paper cups to a corresponding position below the glue coating device. The weighing device, glue nozzle cleaning device, and glue nozzle centering device are respectively arranged in conjunction with the glue coating device. This device uses automatic glue coating to coat paperboard. Compared with the existing technology, the labor cost used is low, the production efficiency is high, and the glue coating is easy to control. However, it still has many shortcomings. For example, the glue coating device is greatly affected by the shape of the paper cup. For example, if the cup body has a certain curvature, the glue cannot be applied to the predetermined position during the molding process. When used, it needs to be used for vertical wall paper cups.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0043] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0044] See also Figure 1-21 , a paper cup inner and outer layer processing and forming device, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the apparatus comprises a paper cup outer layer processing and forming device 1 and a paper cup inner layer processing and forming device 2. The outer layer processing and forming device 1 and the inner layer processing and forming device 2 have the same structure, but the size of the outer layer formed by the outer layer processing and forming device 1 is different from the size of the inner layer formed by the inner layer processing and forming device 2. Both the outer layer processing and forming device 1 and the inner layer processing and forming device 2 comprise a paper winding mechanism 11, a paper cutting mechanism 12, a paper feeding mechanism 13 and a forming mechanism 14.

The forming mechanism 14 mainly absorbs the outer layer of the paper cup to the bottom of the outer layer demoulding mold 147 through the micropores at the bottom of the outer layer demoulding mold, and then, driven by the pneumatic guide slider, moves horizontally to the top of the outer layer molding mold of the paper cup. The cylinder piston rod is pressed down, and at the same time, the outer layer demoulding mold of the paper cup begins to inflate, so that its wall begins to expand outward, so that the paper piece is close to the inner wall of the molding mold 149, and then the micropores on the blades of the molding mold 149 begin to inject glue to form the outer or inner layer of the paper cup.

[0046] like Figure 9 and Figure 13 As shown, the paper winding mechanism 11 is arranged on both sides of the paper cutting mechanism 12; the paper winding mechanism 11 includes an upper roller 1112 and a lower roller 1113, and the two ends of the upper roller 1112 and the lower roller 1113 are respectively arranged on the support plate I 118 and the support plate II 1116 through the upper roller side plate 1110 and the lower roller side plate 1111, and the support plate I 118 and the support plate II 1116 are fixed to the bottom plate 1115 by bolts; limiting rods 1114 are also provided on both sides of the upper roller 1112 and the lower roller 1113, and the limiting rods 1114 are arranged between the support plate I 118 and the support plate II 1116.

[0047] A spring support plate 119 for supporting the spring I115 is provided in the support plate I118 and the support plate II1116. The spring support plate 119 is connected to the two ends of the upper roller 1112 through the upper roller side plate 1110 and is connected to the upper roller 1112 through a bearing. The spring support plate 119 can drive the upper roller 1112 to move up and down; the spring support plate 119 supports the crankshaft bracket 113 through at least four springs I115. The crankshaft bracket 113 is provided with a horizontal pressure plate 117 and a vertical pressure block 114, and the crankshaft bracket 113 is also provided with a crankshaft 112 and a crank handle 111. The horizontal pressure plate 117 is provided above the spring support plate 119, and the vertical pressure block 114 is provided between the horizontal pressure plate 117 and the crankshaft 112. The distance between the upper roller 1112 and the lower roller 1113 is adjusted by pressing or raising the crank handle 111; the upper roller 1112 and the lower roller 1113 are driven by the motor I116.

[0048] like Figure 10 、 Figure 14 and Figure 15As shown, the paper cutting mechanism 12 is arranged on the paper feeding mechanism 13, and the paper cutting mechanism 12 includes a cutter 123 and a paper cutting platform 124. The cutter 123 is driven by the cylinder I 121, and the cylinder I 121 is fixed to the cylinder bracket 122 by the fastening bolt 125. The cutter 123 is located under the cylinder bracket 122, and the cylinder bracket 122 is supported by the bracket column 126; the paper cutting platform 124 is arranged below the cutter 123, and the paper cutting platform 124 is supported by the platform pillar 127; the cutter 123 is connected to the piston rod end of the cylinder I 121 through a threaded connection, and the cylinder I 121 drives the cutter 123 to reciprocate in the vertical direction.

[0049] like Figure 11 、 Figure 16 and Figure 17 As shown, the paper feeding mechanism 13 is connected to the forming mechanism 14 through a conveyor belt. The paper feeding structure includes a paper feeding platform 131, which is supported by a platform column 1312. A chute is provided on the paper feeding platform 131, in which a paper hooking slider 1310 is provided. A slider connecting rod 132 is fixedly connected to the hooking slider 1310. The slider connecting rod 132 is connected to the driven rod 133 through a bearing, and the driven rod 133 is connected to the active rod 134 through a bearing. The active rod 134 is fixedly connected to the main shaft 135 through a cylindrical pin 139, and the active rod 134 is connected to the cylindrical pin 135 through a link 1313. Pin 139; the main shaft 135 is fixed by a fixed support 136 through a bearing, and the lower end of the main shaft 135 is connected to a bevel gear I137, which is vertically connected to a bevel gear II138, and the bevel gear II138 is driven by a motor II1311; the horizontal rotation is converted into vertical rotation by the bevel gear I137 and the bevel gear II138, and the main shaft 135 drives the active rod 134 to perform a circular motion on the horizontal plane, thereby driving the slider connecting rod 132 and the hook paper slider 1310 to perform a horizontal reciprocating motion, and hooking the outer or inner layer of the paper cup to the forming mechanism 14.

[0050] like Figure 12 and Figure 18As shown, the forming mechanism 14 is connected to the paper cup combined forming device, and the forming mechanism 14 includes at least two demoulding molds 147 and at least one forming mold 149; the demoulding mold 147 is provided with a blowing member 146, and the demoulding mold 147 is driven by the cylinder II 141; the forming mold 149 is arranged below the demoulding mold 147 and supported by the forming mold bracket 1410. The forming mold 149 includes an opening and closing block 1415 and a mold bottom 1416; the bottom hole of the forming mold 149 is bonded through the upper end of the glue feeding conduit 1411; the forming mold 149 moves downward under the pressure of the piston rod of the cylinder II 141, and the demoulding mold 147 begins to inflate. After the blades of the forming mold 149 contact the upper surface of the forming mold bracket 1410, the blades begin to close. During the closing process, the glue feeding conduit 1411 injects glue into the blades of the forming mold 149 to form the outer layer or inner layer of the paper cup.

[0051] The demoulding mold 147 is mainly characterized by being able to inflate and expand the cup to be stamped. When demoulding, the air is exhausted to make the demoulding mold 147 smaller, making it easier to demould from the inside of the cup. There are also negative pressure suction holes at the bottom of the demoulding mold 147, which are used to suck the cut paper pieces and send them to the opening and closing forming mold 149.

[0052] The forming mold support 1410 includes a mold support column 1413 and a support base plate 1417 . A spring II 1414 is also provided inside the forming mold support 1410 .

The guide rail support frame 143 is supported by the support frame pillar 1412; the demolding mold 147 and the forming mold 149 are driven to move by the vertical reciprocating motion of the piston rod of cylinder II 141 and the lateral reciprocating motion of the pneumatic guide rail slider 145.

[0054] like Figure 19 、 Figure 20 and Figure 21As shown, the blowing part 146 and the demoulding mold 147 are driven by the cylinder II 141 to perform reciprocating motion in the vertical direction. The demoulding mold 147 absorbs the paper piece 1314 cut and formed from the paper cup body through the tiny holes at the bottom by means of negative pressure. Then, the pneumatic guide rail slider 145 drives the cylinder fixing part 142 to perform transverse reciprocating motion, thereby driving the cylinder II 141 to perform transverse reciprocating motion to transport the paper piece 1314 cut and formed from the paper cup body to the top of the forming mold 149. Then, the cylinder II 141 presses down, and at the same time, the demoulding mold 147 is inflated. When it contacts the forming mold 149 during the pressing process, it drives it to press down at the same time. After contacting the forming mold bracket 1410, the leaves of the paper cup forming mold 149 close, and at the same time, the glue feeding conduit 1411 starts to feed glue to fit the paper piece 1314 cut and formed from the outer or inner layer of the paper cup body.

[0055] The paper feeding mechanism 13 of the paper cup outer layer processing and forming device 1 is connected to the forming mechanism 14 of the paper cup outer layer processing and forming device 1 through a conveyor belt I 31; the paper feeding mechanism 13 of the paper cup inner layer processing and forming device 2 is connected to the forming mechanism 14 of the paper cup inner layer processing and forming device 2 through a conveyor belt III 33.
