Description

Technical Field

[0001] The invention relates to the technical field of labeling processing, in particular to packaging equipment for self-adhesive labels. Background Art

[0002] As the market demands for the aesthetics and recognition of product packaging, self-adhesive labels have become the preferred labeling form for many products due to their convenience and cost-effectiveness. Currently, the application of self-adhesive labels has been widely used in many industries such as food, beverages, and daily chemicals. However, the traditional manual labeling method is not only time-consuming and labor-intensive, but also difficult to ensure the accuracy and flatness of the labeling, which limits the production efficiency and product quality of enterprises.

[0003] The common automatic labeling machines on the market currently use roller pressing or cylinder driving to achieve label attachment. The roller pressing labeling machine uses a rotating roller to press the label flat onto the product surface. It has a high labeling speed and good adaptability, but it is easy to produce label wrinkles or bubbles when processing products with complex shapes. On the other hand, the cylinder-driven labeling machine uses a cylinder to drive the label head to move up and down to press the label onto the product. Although this method can better cope with products of different materials and shapes, the labeling speed is relatively slow, the equipment is more complex, and the maintenance cost is higher.

[0004] In the prior art, both roller pressing and cylinder driven labeling methods have problems to varying degrees, which seriously affect the labeling quality and production efficiency and cannot fully meet the high standards of modern industrial production. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a packaging device for self-adhesive labels, which solves the problems of low precision and efficiency of self-adhesive labels.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a packaging device for self-adhesive labels, comprising: A base, the base is used to support the entire device, four support legs are fixedly connected to the top of the base, a support frame is fixedly connected between the tops of two adjacent support legs on the left and right, a limit plate is provided on the tops of the two support frames, a conveyor belt is provided between the front and rear support frames, and the front support frame is fixedly connected to a first drive motor; A support seat, the support seat is located on the top of the base, the support seat is used to bear the load, a sliding plate is arranged on the top of the support seat, a fixed plate is fixedly connected to the front side of the top of the sliding plate, a separation head is fixedly connected to the front side of the fixed plate, a label conveying mechanism is installed on the right side of the top of the fixed plate, and the label conveying mechanism is used for conveying labels and collecting oil paper; The extrusion mechanism is located on the right side of the separation head and is used to extrude and flatten the label.

[0007] Preferably, the extrusion mechanism includes a connecting frame, a first sliding groove is opened on both sides of the front and rear inner walls of the connecting frame, a second sliding groove is opened on both sides of the front and rear inner walls of the connecting frame, two of the second sliding grooves are located on the right side of the first sliding groove, two of the first sliding grooves and the top of the inner walls of the second sliding grooves are fixedly connected with springs, a scraper is slidably connected between the two first sliding grooves, sliding blocks are slidably connected in the two second sliding grooves, and an extrusion roller is rotatably connected between the two sliding blocks.

[0008] Preferably, the label conveying mechanism includes a second drive motor, which is fixedly connected to the fixed plate, a collecting roller is fixedly arranged at the output end of the second drive motor, a label roller is rotatably connected to the right side of the top of the fixed plate, a first transition roller is arranged at the bottom of the label roller, and a second transition roller is arranged at the front side of the fixed plate.

[0009] Preferably, the first transition roller is located at the front side of the fixed plate, and the fixed plate is rotationally connected to the first transition roller.

[0010] Preferably, two springs are arranged in each of the two second sliding grooves to apply downward pressure to the sliding block, and one spring is arranged in each of the two first sliding grooves to apply downward force to the scraper.

[0011] Preferably, two front and rear adjacent springs are fixedly connected to the scraper, and two right adjacent springs are fixedly connected to the sliding block.

[0012] Preferably, a plurality of connection blocks are fixedly connected to opposite sides of the two support frames, screw rods are threadedly connected to the outer sides of the plurality of connection blocks, and the screw rods on adjacent sides are rotatably connected to the limiting plates on adjacent sides.

[0013] Preferably, the rear limiting plate is slidably connected to the right side of the fixing plate.

[0014] Preferably, a cylinder is fixedly connected to the top of the sliding plate, and an output end of the cylinder is slidably connected to a support seat.

[0015] Preferably, the second transition roller is rotatably connected to the fixed plate.

[0016] Working principle: First, place the self-adhesive label on the label roller, the second drive motor starts working, and its output end drives the collecting roller to rotate. The label is output from the label roller and passes through the first transition roller, the separation head and the second transition roller in sequence for guidance and transmission; When the label passes through the separation head, the oil paper is initially separated from the label, and the oil paper is collected by the collecting roller. Then, the separated label is attached to the product and enters the squeezing mechanism. In the squeezing mechanism, the spring in the first sliding groove in the connecting frame exerts a downward force on the scraper, so that the scraper first contacts the label to perform preliminary flattening and compacting of the label. At the same time, the spring in the second sliding groove exerts a downward pressure on the sliding block, so that the sliding block drives the squeezing roller to perform secondary squeezing on the label, further ensuring the flatness of the label. During the working process, the position of the limit plate can be adjusted by rotating the screw rod to adapt to the labeling of products with different widths. When the limit plate at the rear side moves, it will drive the fixed plate to move together, and when the fixed plate moves, the sliding plate follows the movement. When the height position of the separation head and the fixed plate needs to be adjusted, the cylinder is started, and the output end of the cylinder extends to lift the sliding plate and all the structures on the sliding plate; Start the first drive motor to make the conveyor belt run, driving the product to move.

[0017] The present invention provides a packaging device for self-adhesive labels. It has the following beneficial effects: 1. The present invention ensures the continuity of the labeling process by conveying the items to be labeled. The label conveying mechanism cooperates with the separation head and the extrusion mechanism to accurately attach the label to the item, thereby improving the labeling accuracy. The scraper and the extrusion roller in the extrusion mechanism scrape and extrude the label to ensure that the label is flat and firmly attached to the surface of the item, thereby ensuring product quality and improving the labeling efficiency and accuracy.

[0018] 2. The label conveying, separation, labeling and leveling of the entire equipment of the present invention are all completed by motor drive and automation mechanism, without frequent manual intervention and operation. The first drive motor drives the conveyor belt to automatically convey the items, the second drive motor controls the label conveying, and the cylinder adjusts the height position, realizing highly automated operation, greatly reducing manpower requirements, and is suitable for efficient operation during large-scale production.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: Please see attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides a packaging device for a self-adhesive label, comprising: Base 1, base 1 is used to support the whole equipment, four support legs 4 are fixedly connected to the top of base 1, support frame 2 is fixedly connected between the tops of two adjacent support legs 4 on the left and right, limit plates 25 are arranged on the tops of two support frames 2, a conveyor belt 6 is arranged between the front and rear support frames 2, and a first drive motor 5 is fixedly connected to the front support frame 2; Support seat 9, support seat 9 is located at the top of base 1, support seat 9 is used to bear load, a sliding plate 10 is arranged on the top of support seat 9, a fixed plate 3 is fixedly connected to the front side of the top of sliding plate 10, a separation head 15 is fixedly connected to the front side of fixed plate 3, a label conveying mechanism is installed on the right side of the top of fixed plate 3, and the label conveying mechanism is used for conveying labels and collecting oil paper; The extrusion mechanism is located on the right side of the separation head 15 and is used to extrude and flatten the label.

[0023] The four supporting legs 4 are made of high-strength 6061-T6 aluminum alloy profiles, which not only enhance the overall stability of the equipment, but also ensure the structural strength while reducing the weight. The limit plate 25 can effectively limit the movement range of the items to be packaged on the conveyor belt 6, ensuring that the items remain neat and stable during the conveying process. The conveyor belt 6 is made of polyurethane material, which has strong bearing capacity and good mute effect. How the motor drives the conveyor belt to work belongs to the prior art and is not described in detail. The output end of the cylinder 24 is downward. When the output end of the cylinder 24 extends, the sliding plate 10 is lifted upward, and all structures on the sliding plate 10 are lifted together. When the sliding plate 10 rises, the fixed plate 3 on the top of the sliding plate 10 slides with the limit plate 25 at the rear side. The separation head 15 is made of Teflon material to reduce the friction coefficient and prevent label damage. It can effectively separate the oil paper and label of the self-adhesive label, and prepare for the subsequent label bonding. The collecting roller 12 fixedly arranged at the output end of the second driving motor 7 can collect the oil paper. The first transition roller 13 and the second transition roller 14 arranged at the bottom of the label roller 11 can reasonably guide and adjust the conveying path of the label to ensure that the label remains flat and stable during the conveying process and avoids wrinkles or deviations, thereby improving the accuracy and quality of label fitting.

[0024] The extrusion mechanism includes a connecting frame 16, a first sliding groove 18 is opened on both the front and rear sides of the inner wall of the connecting frame 16, a second sliding groove 19 is opened on both the front and rear sides of the inner wall of the connecting frame 16, the two second sliding grooves 19 are both located on the right side of the first sliding groove 18, a spring 20 is fixedly connected to the top of the inner wall of the two first sliding grooves 18 and the second sliding grooves 19, a scraper 17 is slidably connected between the two first sliding grooves 18, a sliding block 21 is slidably connected in the two second sliding grooves 19, and an extrusion roller 22 is rotatably connected between the two sliding blocks 21.

[0025] The surface of the squeezing roller 22 is polished and is smooth and wear-resistant. The connecting frame 16 provides a frame structure for the internal sliding components. The first sliding groove 18 and the second sliding groove 19 provide guidance for the sliding of the scraper 17 and the sliding block 21. The spring 20 in the first sliding groove 18 enables the scraper 17 to have a downward force, which can initially scrape and flatten the passing label to remove existing bubbles and wrinkles. The two springs 20 in the second sliding groove 19 enable the sliding block 21 to have a downward pressure, thereby driving the squeezing roller 22 to further extrude and flatten the label to ensure that the label is firmly and flatly attached to the surface of the object.

[0026] The label conveying mechanism includes a second drive motor 7, which is fixedly connected to the fixed plate 3. A collecting roller 12 is fixedly arranged at the output end of the second drive motor 7. A label roller 11 is rotatably connected to the right side of the top of the fixed plate 3. A first transition roller 13 is arranged at the bottom of the label roller 11, and a second transition roller 14 is arranged on the front side of the fixed plate 3.

[0027] The first transition roller 13 is located at the front side of the fixed plate 3 , and the fixed plate 3 and the first transition roller 13 are rotationally connected.

[0028] Two springs 20 are arranged in each of the two second sliding grooves 19 for applying downward pressure to the sliding block 21 , and one spring 20 is arranged in each of the two first sliding grooves 18 for applying downward force to the scraper 17 .

[0029] The two front and rear adjacent springs 20 are fixedly connected to the scraper 17 , and the two right adjacent springs 20 are fixedly connected to the sliding block 21 .

[0030] Two springs 20 can provide a stronger and more uniform downward pressure for the sliding block 21, so that the squeezing roller 22 can squeeze and flatten the label more effectively. One spring 20 provides a moderate downward force for the scraper 17, which can achieve a preliminary flattening effect without causing excessive pressure on the label.

[0031] A plurality of connection blocks 23 are fixedly connected to opposite sides of the two support frames 2 , and screw rods 8 are threadedly connected to the outer sides of the plurality of connection blocks 23 . The screw rods 8 on adjacent sides are rotationally connected to the limiting plates 25 on adjacent sides.

[0032] The rear limiting plate 25 is slidably connected to the right side of the fixing plate 3 .

[0033] A cylinder 24 is fixedly connected to the top of the sliding plate 10 , and an output end of the cylinder 24 is slidably connected to the support seat 9 .

[0034] The second transition roller 14 is rotatably connected to the fixed plate 3 .

[0035] The separation head 15, the squeezing roller 22 and the scraper 17 are all wearing parts, and the user can replace them with new parts of the same specification and model according to the actual situation.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
