Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, specifically relating to labeling and packing machines. Background Technology

[0002] In modern industrial production, labeling and packaging are key processes before products leave the factory, and mechanized equipment has been widely used to replace manual operations. However, existing technologies still have significant shortcomings: First, most labeling equipment is single-function, capable of only labeling one side. If double-sided labeling is required, it must be done in steps using multiple machines, which not only increases equipment investment but also leads to low labeling efficiency due to product transfer. Second, some double-sided labeling equipment lacks precise positioning and conveying structures, making products prone to shifting during transport, resulting in inconsistent label placement, wrinkles, or detachment, affecting product information identification and appearance quality. Third, the labeling and packaging processes are poorly integrated. Labeled products require manual or additional equipment for arrangement and sorting before being boxed, and it is difficult to adapt to the multi-row packing requirements of different sized boxes, resulting in low efficiency and poor space utilization in the packaging process.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that this application can coordinate the control of various motors in this application by setting up a control module, such as the Huacheng Industrial Control ESTS2 general bus servo control system with an ARM processor, and install and connect position sensors to collect information on the product queuing status and whether the product is in the labeling operation position, thereby providing control basis for the control module to realize automated labeling and packaging. Alternatively, it can be achieved through manual control, or by designing the product conveying interval in conjunction with the preset working mode of the motor.

[0016] Example 1 Labeling and packaging machines, such as Figure 1 , Figure 2 As shown, it includes: Conveyor belt 10; The product to be labeled is placed on the first end of the conveyor belt 10. When the conveyor belt 10 is running, the product to be labeled moves from the first end of the conveyor belt 10 to the second end. The width of the conveyor belt 10 is equal to the width of the product to be labeled. The conveyor belt 10 includes a bracket, a plurality of support cylinders rotatably mounted on the bracket, a motor that drives at least one support cylinder to rotate, and an elastic belt fitted on the support cylinder. The bracket is also provided with two limiting plates. The two limiting plates are used to limit the product on the conveyor belt 10 to prevent it from falling. The height of the limiting plates above the conveyor belt 10 is less than the height of the product to be labeled. Left labeling device; The left labeling device is located on the left side of the first end of the conveyor belt 10. The left labeling device is used to perform labeling operation on the left side of the product to be labeled on the conveyor belt 10. Right labeling device; The right labeling device is located on the right side of the second end of the conveyor belt 10. The right labeling device is used to label the right side of the product to be labeled on the conveyor belt 10. Arrangement and placement device; The arrangement and placement device is set on the second end of the conveyor belt 10. The arrangement and placement device is used to arrange the labeled products on the second end of the conveyor belt 10 and place them in the packaging box 1.

[0017] In this embodiment, the left and right labeling devices complete the labeling of both sides of the product in stages. The arrangement and placement device receives the labeled products and completes the packaging, forming a continuous process of "conveying-labeling-packaging". The integrated structure achieves seamless connection between labeling and packaging, reduces product transfer links, solves the problem of process fragmentation in existing equipment, and greatly improves overall production efficiency. The width of the conveyor belt 10 is adapted to the product to ensure accurate labeling position and avoid label misalignment caused by product offset.

[0018] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 1 As shown, the left labeling device includes: First mounting plate 4; The first mounting plate 4 is disposed on the left side of the conveyor belt 10, and the top surface of the first mounting plate 4 is on the same horizontal plane as the top surface of the conveyor belt 10. First label rotating cylinder 8; The first label rotating cylinder 8 is vertically mounted on the top surface of the first mounting plate 4 and can be rotated through a fixed shaft. The A-side label sticker 6 is wound around the outer side of the first label rotating cylinder 8, and its first end is fixed to the rotating cylinder. First acute angle baffle 5; The first acute angle baffle 5 is vertically mounted on the first mounting plate 4, and the first side of the acute angle end of the first acute angle baffle 5 is parallel to the conveyor belt 10 and the second side is located to the left of the first side; The first stepper motor; the shaft of the first stepper motor is set vertically; First label recycling bin 9; The first label recycling bin 9 is mounted on the rotating shaft of the first stepper motor. The second end of the label sticker 6 on side A passes through the second side of the acute angle end of the first acute angle baffle 5, goes around the acute angle end of the first acute angle baffle 5, and is then fixedly connected to the outer side of the first label recycling bin 9 via the first side of the acute angle end of the first acute angle baffle 5.

[0019] In this embodiment, the first stepper motor drives the first label recycling cylinder 9 to rotate at a preset angle, pulling the A-side label sticker strip from the first label rotating cylinder 8. When the sticker strip passes the acute angle end of the first acute angle baffle 5, the softer backing paper turns towards the recycling cylinder with the acute angle end, and the harder sticker part separates from the backing paper. When the product passes by with the conveyor belt 10, the separated sticker part is pasted to the left side of the product. At this time, the first stepper motor continues to rotate at a preset angle. While the pasted part is pulled with the product, the remaining sticker part continues to be released until the entire sticker part is separated from the backing paper, completing the left side labeling.

[0020] Example 3 The difference between this embodiment and Embodiment 2 is that, as Figure 1 As shown, the right labeling device and the left labeling device are distributed in a mirror image symmetrically along the conveyor belt 10. The right labeling device includes: Second mounting plate; The second mounting plate is disposed on the right side of the conveyor belt 10, and the top surface of the second mounting plate is on the same horizontal plane as the top surface of the conveyor belt 10; The second label rotating cylinder is vertically mounted on the top surface of the second mounting plate and can be rotated through a fixed shaft. The B-side label sticker is wound around the outer side of the second label rotating cylinder, and its first end is fixed to the rotating cylinder. Second acute angle baffle; The second acute angle baffle is vertically installed on the second mounting plate, with the first side of the acute angle end of the second acute angle baffle being parallel to the conveyor belt 10 and the second side being located to the right of the first side; Second stepper motor; the shaft of the second stepper motor is set vertically; The second label recycling bin is mounted on the shaft of the second stepper motor. The second end of the label sticker on side B passes through the second side of the acute angle end of the second acute angle baffle, goes around the acute angle end of the second acute angle baffle, and is then fixedly connected to the outer side of the second label recycling bin via the first side of the acute angle end of the second acute angle baffle.

[0021] In this embodiment, the second stepper motor drives the second label recycling cylinder to rotate by a preset angle, pulling the B-side label sticker tape out of the second label rotating cylinder. When the sticker tape passes the acute end of the second acute angle baffle, the softer backing paper turns towards the recycling cylinder with the acute angle end, and the harder sticker part separates from the backing paper. When the product passes by with the conveyor belt 10, the separated sticker part is pasted to the right side of the product. At this time, the second stepper motor continues to rotate by a preset angle. While the pasted part is pulled with the product, the remaining sticker part continues to be released until the entire sticker part is separated from the backing paper, completing the labeling on the right side.

[0022] Example 4 The difference between this embodiment and embodiment 3 is that, as Figure 1 and Figure 3 As shown, the labeling and packaging machine also includes two pressing devices, which are used to press the A-side label sticker strip 6 on the first label rotating drum 8 and the B-side label sticker strip on the second label rotating drum, respectively.

[0023] In this embodiment, two pressing devices apply continuous pressure to the A-side label sticker tape and the B-side label sticker tape respectively, ensuring that the sticker tape is always taut during the conveying process and avoiding label position deviation due to slack.

[0024] Example 5 The difference between this embodiment and embodiment 4 is that, as Figure 1 and Figure 3 As shown, a pressing device includes: Fixing plate 7; Fixing plate 7 is vertically fixedly installed on the first mounting plate 4 or the second mounting plate; Sleeve 17; One end of sleeve 17 is fixedly installed on the side of fixing plate 7; Compression spring 16; Compression spring 16 is disposed inside sleeve 17, and the first end of compression spring 16 is fixedly connected to fixed plate 7. Push rod 18; The first end of push rod 18 is located inside sleeve 17, and the second end of push rod 18 is located outside sleeve 17. The first end of push rod 18 is fixedly connected to the second end of compression spring 16. Rectangular ring 19; Rectangular ring 19 is set vertically, and the first side of rectangular ring 19 is fixedly connected to the second end of push rod 18; Roller 20; Roller 20 is rotatably mounted on the second side of rectangular ring 19, and roller 20 is in pressure contact with the A-side label sticker on the first label rotating drum 8 or the B-side label sticker on the second label rotating drum.

[0025] In this embodiment, the compression spring 16 pushes the rectangular ring 19 through the push rod 18, so that the roller 20 is always in pressure contact with the label sticker tape. The pressure is automatically adjusted by the spring force to ensure that the sticker tape is taut and not damaged by excessive compression.

[0026] Example 6 The difference between this embodiment and embodiment 3 is that, as Figure 1 As shown, the labeling and packaging machine also includes two sponge cylinders 2. One sponge cylinder 2 is rotatably and vertically mounted on the first mounting plate 4 via a fixed shaft and is located between the first acute-angle baffle 5 and the arrangement and placement device. The other sponge cylinder 2 is rotatably and vertically mounted on the second mounting plate via a fixed shaft and is located between the second acute-angle baffle and the arrangement and placement device. The two sponge cylinders 2 are distributed in a mirror symmetrical manner along the conveyor belt 10. After the labeling operation of the A-side label and B-side label of the product to be labeled is completed, the labeled product moves with the conveyor belt 10 and rolls and squeezes the two sponge cylinders 2, causing the two sponge cylinders 2 to deform and squeeze the A-side label and B-side label of the labeled product respectively.

[0027] In this embodiment, when the product passes through the sponge tube 2 after being labeled, the sponge tube 2 deforms elastically to fit the side of the product, applying uniform pressure to the label to ensure that the label is tightly attached to the product surface and to prevent it from lifting or falling off.

[0028] Example 7 The difference between this embodiment and Embodiment 1 is that, as Figure 1 and Figure 2 As shown, the arrangement and placement device includes: Packaging box 1; Packaging box 1 is located on the lower left side of conveyor belt 10; First telescopic motor 14; First telescopic motor 14 is fixedly installed on the right side of conveyor belt 10; Loading box 13; Loading box 13 is a box structure without top or first side. The third side of loading box 13 is fixedly connected to the push shaft of the first telescopic motor 14. The bottom surface of the end where the fourth side of loading box 13 is located is provided with a strip-shaped opening with the same width as the conveyor belt 10. The second end of the conveyor belt 10 passes through the side of loading box 13 without a top and is set on the strip-shaped opening. The part of the conveyor belt 10 located inside the loading box 13 is not provided with a limiting plate. Pad 15; Pad 15 is fixedly installed in the loading box 13; Second telescopic motor 12; The second telescopic motor 12 is fixedly installed on the pad 15, and the push shaft of the second telescopic motor 12 is set to the fourth side of the loading box 13; Push plate 11; Push plate 11 is fixedly installed on the drive shaft of the second telescopic motor 12. Push plate 11 is located above the right side of the conveyor belt 10. The distance between push plate 11 and the fourth side of the loading box 13 is equal to the width of the conveyor belt 10. When the labeled products move to the second end of the conveyor belt 10, the labeled products accumulate in the loading box 13 to a preset quantity. Then, the second telescopic motor 12 drives push plate 11 to clamp the products. The first telescopic motor 14 drives the loading box 13 to move above the packaging box 1. The second telescopic motor 12 retracts to make the products fall into the packaging box 1. If multiple rows need to be packed, the extension of the first telescopic motor 14 can be adjusted and the operation repeated.

[0029] In this embodiment, the products are stacked in rows along the width of the conveyor belt 10 inside the loading box 13. The push plate 11 is driven by the second telescopic motor 12 to clamp the rows with the fourth side. The first telescopic motor 14 drives the loading box 13 to move to the corresponding position of the packaging box 1. After release, the packing is completed. When packing multiple rows, the position can be switched by adjusting the telescopic amount, so as to realize the automatic arrangement and packing of the products after labeling. It can adapt to the multi-row requirements of packaging boxes 1 of various specifications, solve the problems of poor adaptability and low space utilization of existing packaging equipment, and improve the automation and flexibility of the packing process. At the same time, in order to ensure that the rebound distance and landing damage are minimized as much as possible after the products fall, the height of the conveyor belt 10 from the packaging box 1 can be adjusted according to the nature of the products. The packaging box 1 can be manually removed after being filled and empty boxes can be placed. Alternatively, it can be transferred by a belt conveyor.

[0030] Example 8 The difference between this embodiment and Embodiment 7 is that the side of the push plate 11 that contacts the labeled product is made of rubber. The rubber contact surface undergoes elastic deformation when the push plate 11 clamps the product, increasing the contact area and buffering the pressure to prevent the product surface from being squeezed and damaged.

[0031] Example 9 The difference between this embodiment and embodiment 7 is that the conveyor belt 10 is made of PVC. PVC material has the characteristics of wear resistance and smooth surface, which ensures that the products move smoothly during the conveying process. At the same time, it can also allow the products to slide and rub against the conveyor belt 10 during the queuing process, so as to prevent taller products from tipping over due to excessive friction.

[0032] Those skilled in the art will recognize that the embodiments described herein are intended to help the reader understand the principles of this application, and should be understood as not limiting the scope of protection of this application to such specific statements and embodiments. Various modifications and variations can be made to this application by those skilled in the art.
