Description

Technical Field

[0001] The utility model relates to the technical field of paper cup printing, in particular to a multi-color positioning printing mechanism. Background Art

[0002] Paper cups are made by mechanically processing and gluing base paper (white paperboard) made from chemical wood pulp into a paper container with a cup-shaped appearance. Paper cups for frozen foods are waxed and can hold ice cream, jam, butter, etc. During the production process of paper cups, the cut paperboard needs to be printed to enhance the appearance of the paper cups, increase their added value, and meet the diverse needs of the market and consumers.

[0003] In the prior art, a Chinese patent with publication number CN212046398U provides a cup body cardboard printing device for paper cup processing, including a machine body, a motor, a conveyor belt, a printing roller, a supporting moving rod, a fixing plate, a heating device, a replacement and maintenance door, a handle, a hand wheel, a fixing rod, a fixing block, a moving box, a connecting rod, a brush, a waste collection box and a switch group. A printing roller is provided above the machine body, wherein a supporting moving rod is provided on one side of the printing roller, and a fixing plate is welded above the supporting moving rod, and a heating device is provided below the fixing plate; a moving box is provided inside the replacement and maintenance door, wherein the moving box is connected to the brush through a connecting rod, and the brush contacts the conveyor belt. The utility model has a moving box, a supporting moving rod and a brush, which are simple in structure and easy to adjust, and are convenient for preventing waste residue from falling onto the conveyor belt during printing and causing the inside of the machine body to be dirty and messy, and are convenient for market promotion and application.

[0004] However, in actual use, the above scheme still has some shortcomings. When the cardboard is conveyed to the bottom of the printing roller, there is a lack of a guiding device, which causes the position of the cardboard to shift during the conveying process, resulting in irregular patterns on the surface of the printed cardboard, generating waste and increasing the cost of the production process. In addition, since the cardboard has two curved sections, directly restricting and guiding the two sides of the cardboard can easily cause the cardboard to wrinkle, resulting in unclear printed patterns. Therefore, a multi-color positioning printing mechanism is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the embodiment, Figure 1-5 A multi-color positioning printing mechanism is given. The utility model includes a conveyor table 1. A positioning component 2 extending to the middle above the conveyor table is arranged on the outer side of the conveyor table 1. A U-shaped frame 3 is fixedly installed on the outer side of the conveyor table 1. An optical detector 4 is fixedly installed on the bottom of the U-shaped frame 3. Support plates 5 are fixedly installed on the front and rear sides of the conveyor table 1. A printing machine body 6 is fixedly installed between the two support plates 5. A collecting component 7 is fixedly installed on the right side of the conveyor table 1. A cardboard body 8 is placed on the top of the conveyor table 1.

[0026] As a preferred embodiment of the present invention, the positioning assembly 2 includes a positioning block 201 and a positioning plate 202. The number of the positioning blocks 201 is six and they are evenly distributed in groups of three on the front and rear sides of the conveyor platform 1. The rear side of the front positioning plate 202 is in contact with the front side of the cardboard body 8, and the front side of the rear positioning plate 202 is close to the rear side of the cardboard body 8. The six positioning blocks 201 are all provided with a slide groove 203 inside, and the interiors of the front and rear slide grooves 203 are both slidably connected with a slide rod 204, and one end of the front and rear slide rods 204 are respectively fixedly connected to the opposite sides of the two positioning plates 202.

[0027] According to the different sizes of the paperboard body 8 , the position of the slide bar 204 can be adjusted to control the position of the positioning plate 202 , so as to better guide the paperboard body 8 .

[0028] As a preferred embodiment of the present invention, the tops of the two positioning plates 202 are each provided with two positioning grooves 9 which are symmetrically distributed on the left and right sides. Positioning rods 10 are movably installed inside the four positioning grooves 9. The tops of the four positioning rods 10 are fixedly connected to the bottom of the connecting frame 11. A limiting frame 12 is fixedly installed at the bottom of the connecting frame 11. The limiting frame 12 is located above the cardboard body 8.

[0029] The top of the cardboard body 8 can be protected to prevent the cardboard body 8 from warping when entering the positioning assembly, and the cardboard body 8 can be regulated so that the cardboard body 8 is in a stable state.

[0030] As a preferred embodiment of the present invention, the collecting component 7 includes a supporting box 701, which is fixedly mounted on the right side of the conveying platform 1, and a collecting box 702 is movably mounted inside the supporting box 701. A storage groove 703 is provided on the top of the inner wall of the supporting box 701, and a weight detector 704 is fixedly mounted inside the storage groove 703. The bottom of the collecting box 702 is fitted with the top of the weight detector 704, and an alarm light 705 is fixedly mounted on the top of the supporting box 701, and the alarm light 705 is electrically connected to the weight detector 704.

[0031] Grooves are provided on the front and rear sides of the inner wall of the collection box 702 to facilitate direct replacement of the collection box 702. The weight detector 704 detects that the weight of the collection box 702 exceeds the standard and reminds the staff to replace it, so as to facilitate the subsequent sorting of the cardboard bodies 8 entering the collection box 702 and prevent the cardboard bodies 8 from piling up too much inside the collection box 702, causing inconvenience in the subsequent sorting process.

[0032] As a preferred embodiment of the present invention, a first limiting hole 13 is provided inside the sliding rod 204, and the number of the first limiting holes 13 is several and evenly distributed, a second limiting hole 14 is provided inside the positioning block 201, and a limiting rod 15 is provided inside the positioning block 201 that passes through the first limiting hole 13 and the second limiting hole 14.

[0033] The slide bar 204 is restricted to ensure that the position of the positioning plate 202 remains stable during use.

[0034] As a preference of this embodiment, the size of the second limiting hole 14 matches the size of the first limiting hole 13 .

[0035] Working principle: The straight side of the cardboard body 8 is attached to the rear side of the front positioning plate 202 and placed on the top of the conveying platform 1 for conveying. The rear positioning plate 202 does not forcibly restrict the cardboard body 8 to prevent squeezing force from causing wrinkles on the cardboard body 8. When the cardboard body 8 enters the collection box 702, the weight of the cardboard bodies 8 stacked in the collection box 702 is detected by the weight detector 704 to avoid excessive weight resulting in an excessive number of cardboard bodies 8, causing inconvenience in subsequent sorting.
