Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an automated packaging equipment. Background Technology

[0002] Currently, automated thermoplastic film packaging production lines are widely used in industries such as food, pharmaceuticals, and electronics due to their high efficiency and stability. However, technical bottlenecks still exist in actual production. From a technical perspective, existing production lines first use a heat-sealing method to heat-seal and disconnect the product's sides and front and back. Then, they use hot air circulation or infrared radiation heating to cause the heat-shrink film to shrink and wrap the product.

[0003] Before using a heat shrink machine, the front and back sides and left and right sides of the film are heat-sealed to seal and wrap the product. However, after heat-sealing, the film size is usually larger than the product size, and four corners are formed around the product. Ordinary heat shrink film has limited shrinkage capacity. After the packaging film is separated, the corners are not completely heat-shrinked. After shrinkage, the film material is difficult to completely fit the edges or sides of the product, resulting in wrinkles or bulges at the edges. This incomplete corner cutting not only affects the appearance of the product, but may also cause the film material to be damaged during transportation due to the corners lifting up, reducing the protective performance of the packaging.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] In view of the shortcomings of the prior art, this embodiment provides an automated packaging device, which can be referred to as follows:

[0049] As attached Figure 1 As shown, an automated packaging device includes a first conveyor belt 1, a second conveyor belt 2, two first separators 3, a second separator 4, and a pushing unit 5. The first conveyor belt 1 and the second conveyor belt 2 are connected front to back and arranged at intervals. The two first separators 3 are respectively located on both sides of the first conveyor belt 1. The first separators 3 are existing technology and can heat-seal the sides of the upper and lower films and remove excess parts. The second separators 4 are located between the first conveyor belt 1 and the second conveyor belt 2. The second separators 4 separate the front and rear sides of the film and, together with the two first separators 3, form a cavity for wrapping the product to facilitate subsequent shrinking. The two sides of the second conveyor belt 2 are respectively provided with pushing units 5. The two pushing units 5 can move towards each other to squeeze the left and right sides of the film and form an inward concave portion.

[0050] Specifically, the front ends of the upper and lower films are first separated by the second separator 4 to form a closed surface. At this time, the sides of the upper and lower films are respectively located in the two first separators 3. The product is first conveyed forward by the first conveyor belt 1. When the product reaches the designated position, the two first separators 3 set on both sides of the first conveyor belt 1 start synchronously. Using existing technology, the sides of the upper and lower films are heat-sealed and the excess is removed, and the film is moved with the product. After the product passes the second separator 4, the second separator 4 and the pushing part 5 located between the first conveyor belt 1 and the second conveyor belt 2 start to work. The pushing part 5 moves towards the middle and squeezes the left and right sides of the film to form an inward concave part. Then the second separator 4 separates the rear side of the film, and then it is sent into the heat shrink machine for heat shrinking under the action of the second conveyor belt 2.

[0051] Two pushing parts 5 are arranged opposite to each other. Under the action of the pushing parts 5, inward recesses are formed on the left and right sides of the film. At the same time, the left and right sides of the film change from the original two layers to four layers, while the film in the middle position is still in a two-layer state. At this time, the left and right sides of the film are within the width range of the product. That is, the width of the film after being squeezed on the left and right sides is less than the width of the product. Under the action of the second partition machine 4, the heat-melting break point of the film is located inside the rear surface of the product. Therefore, during heat shrinking, the fold can be laid flat on the rear surface of the product without wrinkles or bulges.

[0052] One embodiment of this application is shown in the appendix. Figure 2 and attached Figure 3 As shown, the pushing part 5 includes an adjustment component 51 and a push rod 52. The adjustment component 51 is disposed on the side wall of the second conveyor, and the push rod 52 is disposed on the adjustment component 51. The adjustment component 51 cooperates with the push rod 52 to adjust the position of the push rod 52 so that the push rod 52 corresponds to the left and right sides of the film. The protruding end of the push rod 52 faces the film so as to facilitate pressing on both sides of the film.

[0053] When products of different sizes enter the second conveyor belt 2, the equipment control system activates the adjustment component 51 based on the product width information to precisely align the left and right edges of the film. The extended end of the push rod 52 is made of elastic rubber, which provides sufficient squeezing force when in contact with the film while avoiding scratching it. Furthermore, the extension stroke of the push rod 52 can be preset to ensure that a suitable inward concave portion is formed when squeezing the film. Whether it is small electronic product packaging or large home appliance packaging, precise pressure and positioning can be achieved through the coordinated work of the adjustment component 51 and the push rod 52, improving the fit and aesthetics of the packaging.

[0054] In this embodiment, a roller 53 is rotatably provided at the extended end of the push rod 52. The roller 53 is a rubber roller. The push rod 52 can be a telescopic component such as a cylinder, an electric telescopic rod, or an electric cylinder.

[0055] Based on the original structure, the extended end of the push rod 52 has been optimized and upgraded, and a bearing is used to achieve a rotatable connection with the roller 53, allowing the rubber roller 53 to rotate freely around the axis. The rubber roller 53 is made of high-elasticity, wear-resistant nitrile rubber, and its surface is treated with a special process to form a smooth surface.

[0056] In this embodiment, as shown in the appendix Figure 2 As shown, the adjustment assembly 51 includes a vertical lead screw module 511 and a mounting plate 512. The vertical lead screw module 511 is disposed on the side wall of the second conveyor belt 2 and is perpendicular to the surface of the second conveyor belt 2. The mounting plate 512 is disposed on the sliding block of the vertical lead screw module 511, and the push rod 52 is disposed on the mounting plate 512.

[0057] The vertical lead screw module 511 and mounting plate 512 allow the push rod 52 to be adjusted vertically to position it in the middle of the product. This facilitates the push rod 52 in extruding the film to form a recess, and also facilitates the subsequent heat shrinking process, thus improving the aesthetic appearance.

[0058] Furthermore, a fixing plate 513 is provided on one side of the vertical screw module 511. The fixing plate 513 is set on the side wall of the second conveyor belt 2, which facilitates the installation of the vertical screw module 511.

[0059] In this embodiment, the mounting plate 512 is provided with a mounting groove, and a through hole is provided in the mounting groove. One end of the push rod 52 is provided in the mounting groove, and the extended end of the push rod 52 is located in the through hole and can extend and retract within the through hole.

[0060] The mounting slot of the mounting plate 512 can be used to limit the push rod 52, and its through hole facilitates the extension and retraction of the extended end of the push rod 52.

[0061] In this embodiment, as shown in the appendix Figure 3 As shown, the adjustment assembly 51 also includes a transverse lead screw module 514, which is disposed on the side wall of the second conveyor belt 2. A vertical lead screw module 511 is disposed on the slider of the transverse lead screw module 514. The length direction of the transverse lead screw module 514 is the same as the rotation direction of the second conveyor belt 2, that is, the transverse lead screw module 514 and the vertical lead screw module 511 are arranged perpendicularly.

[0062] Both the horizontal lead screw module 514 and the vertical lead screw module 511 are existing technologies. The fixing plate 513 of the vertical lead screw module 511 is set on the slider of the horizontal lead screw module 514 so that the horizontal lead screw module 514 can drive the vertical lead screw module 511 to move.

[0063] The adjustment component 51 innovatively integrates the horizontal lead screw module 514 and the vertical lead screw module 511 to construct a two-dimensional precision adjustment system, greatly improving the applicability and adjustment accuracy of the packaging equipment. The horizontal lead screw module 514 is made of high-strength alloy steel and is fixed parallel to the side wall of the second conveyor belt 2. Its length direction is completely consistent with the rotation direction of the conveyor belt, forming a horizontal displacement adjustment channel. The vertical lead screw module 511 is vertically installed on the slider of the horizontal lead screw module 514. The two are arranged in a cross orthogonal layout to construct an XY axis linkage adjustment structure.

[0064] The horizontal lead screw module 514 and the vertical lead screw module 511 can be used to adjust the vertical and horizontal direction of the push rod 52 so that the extended end of the push rod 52 is aligned with the middle position of the product and adjusted to a suitable extrusion position to facilitate the formation of the recess.

[0065] One embodiment of this application is shown in the appendix. Figure 4and attached Figure 5 As shown, the second partition machine 4 includes two guide rods 41, a first sliding plate 43, a first pressure plate 44, a second sliding plate 45, a second pressure plate 46, and a driving component. Connecting plates 42 are provided at the top and bottom of the two guide rods 41 to connect and fix them. The connecting plates 42 at the bottom of the two guide rods 41 can be mounted on the first conveyor belt 1 and / or the second conveyor belt 2. The first sliding plate 43 is slidably mounted on the two guide rods 41, and the two guide rods 41 also restrict the first sliding plate 43. The first pressure plate 44 is located at the bottom of the first sliding plate 43 and is used to squeeze the film. The second sliding plate 45 is slidably mounted on the two guide rods 41, and the second pressure plate 46 is located at the top of the second sliding plate 45. A heating element is provided on the surface of the second pressure plate 46, and the first pressure plate 44 corresponds to the heating element. The driving component is mounted on the two guide rods 41 and cooperates with the first sliding plate 43 and the second sliding plate 45 respectively, so that the first sliding plate 43 and the second sliding plate 45 slide vertically along the guide rods 41.

[0066] Specifically, the first pressure plate 44 and the second pressure plate 46 correspond to each other. When it is necessary to separate the front and rear sides of the film, the driving component can drive the first sliding plate 43 and the second sliding plate 45 to move towards each other. The first pressure plate 44 at the bottom of the first sliding plate 43 squeezes the upper film downward, and the second pressure plate 46 at the top of the second sliding plate 45 squeezes the lower film upward. With the cooperation of the first pressure plate 44 and the second pressure plate 46, both layers of film are squeezed onto the heating component. The heating component heat-melts and seals the two layers of film and cuts them to form a closed opening, which facilitates the subsequent heat shrinking process.

[0067] In this embodiment, both the first sliding plate 43 and the second sliding plate 45 are slidably connected to the two guide rods 41 via sliding bearings.

[0068] In this embodiment, the driving component includes two cylinders, which are respectively disposed on two connecting plates 42. The extended ends of the two cylinders are respectively connected to the first sliding plate 43 and the second sliding plate 45. The two cylinders can drive the first pressure plate 44 and the second pressure plate 46 to move towards or away from each other.

[0069] In this embodiment, as shown in the appendix Figure 6 As shown, the heating assembly includes three heating wires 47, which are arranged in a straight line on the surface of the second pressure plate 46. Adjacent heating wires 47 are spaced apart, and the three heating wires 47 are connected to an external power supply device. The heating wires 47 located at both ends of the second pressure plate 46 (the two ends of the second pressure plate 46 refer to the left and right ends) correspond to the recesses of the film.

[0070] The three heating wires 47 are connected to an external power supply device, which can control the heating intensity of each heating wire 47. Since the recessed part of the film consists of four layers of film, the power of the heating wires 47 at the left and right ends can be increased to facilitate isolation, while the power of the heating wire 47 in the middle can be reduced, thereby saving energy through individual control.

[0071] Furthermore, the gap between the three heating wires 47 is small, so when making separation, the film located between the heating wires 47 can be separated by pulling without affecting the heat shrinking process of the film.

[0072] In this embodiment, the bottom of the first pressure plate 44 is conical, the top of the second pressure plate 46 is set as a conical groove 48, the heating component is located inside the conical groove 48, and the bottom of the first pressure plate 44 cooperates with the conical groove 48.

[0073] By setting the top of the second pressure plate 46 as a conical groove 48, contact with the heating component can be avoided when the second pressure plate 46 presses the lower film; while the upper film and the lower film can contact the heating component and melt under the pressure of the conical part of the first pressure plate 44.

[0074] In one embodiment of this application, the first conveyor belt 1 includes a product conveyor belt 11 and a film partition belt 12. The product conveyor belt 11 and the film partition belt 12 are arranged one behind the other and in a straight line with the second conveyor belt 2. The product conveyor belt 11 is located on the side of the film partition belt 12 away from the second conveyor belt 2. An upper film roller 13 is provided at the top of the product conveyor belt 11, and an upper film is wound on the upper film roller 13. A lower film roller 14 is provided at the bottom of the film partition belt 12, and a lower film is wound on the lower film roller 14.

[0075] The product conveyor belt 11 and the film partition belt 12 are arranged alternately. The upper film and the lower film are matched at the position of the first partition machine 3 and separated by the action of the first partition machine 3. The product moves to the film partition belt 12 under the action of the product conveyor belt 11 and is located between the upper film and the lower film. As the film partition belt 12 is conveyed, the product and the upper and lower films move to the second conveyor belt 2 and are separated by the second partition machine 4.

[0076] In this embodiment, two pushing parts 5 are provided on both the second conveyor belt 2 and the film partition belt 12. The pushing parts 5 on the film partition belt 12 are located between the first partition machine 3 and the second partition machine 4. Through the two pushing parts 5 located on the same side, a regular recess can be formed on the side of the film, which makes it easier for the second partition machine 4 to perform partitioning and the heat shrink machine to perform heat shrinking, and will not form wrinkles or protrusions.

[0077] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the solutions disclosed herein. The present invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
