Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco production technology, specifically relating to a barcode pressing device for cigarette boxes. Background Technology
[0002] Finished cigarette boxes are affixed with barcodes upon leaving the warehouse to identify product information and facilitate traceability in case of quality issues. Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling, hence the widespread use of corrugated cardboard boxes for cigarettes. However, due to its unique structure, the surface of the cigarette boxes is smooth and wavy, causing a decrease in the quality of barcode printing. Barcodes may not adhere completely, resulting in loose edges, curling, or even displacement. During warehousing and transfer, barcodes may wrinkle or fold, making machine recognition difficult, seriously affecting product quality and causing difficulties in product delivery.
[0003] Therefore, how to design a barcode pressing device for cigarette boxes so that the barcode can be firmly attached to the cigarette box has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] The purpose of this invention is to provide a barcode pressing device for cigarette boxes to solve the aforementioned technical problems in the prior art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A barcode pressing device for cigarette boxes includes a support frame, a fixed plate, a first pressure roller, a second pressure roller, a first mounting frame, and a second mounting frame. The support frame is horizontally mounted across the conveying channel of a cigarette box conveying device. The fixed plate is mounted on the support frame and located above the conveying channel. The upper end of the first mounting frame is rotatably connected to the fixed plate, and the first pressure roller is rotatably mounted at the lower end of the first mounting frame. The upper end of the second mounting frame is rotatably connected to the fixed plate, and the second pressure roller is rotatably mounted at the lower end of the second mounting frame. The first and second pressure rollers are parallel, and the diameter of the first pressure roller is larger than the diameter of the second pressure roller. In its natural state, the first pressure roller is located to the lower left of the second pressure roller. An elastic element is provided between the first and second mounting frames, and a limiting element is provided on the first mounting frame for blocking contact with the second mounting frame.
[0007] Preferably, the first mounting frame includes a first rod, a second rod, and a connecting rod. The second rod is parallel to the first rod, and the first rod and the second rod are connected by the connecting rod. The upper ends of the first rod and the second rod are rotatably connected to the rotating shafts provided on the front and rear ends of the fixed plate, respectively. The front and rear ends of the first pressure roller are rotatably connected to the lower ends of the first rod and the second rod, respectively, through axles.
[0008] Preferably, the second mounting bracket has the same structure as the first mounting bracket.
[0009] Preferably, the limiting member is provided on both the first rod and the second rod.
[0010] Preferably, the limiting member is a limiting plate, and the limiting plate has a limiting inclined surface for engaging with the second mounting bracket.
[0011] Preferably, the elastic element is a tension spring.
[0012] The beneficial effects of this utility model are as follows:
[0013] The present invention relates to a barcode pressing device for cigarette boxes. In use, because the first pressure roller is located to the lower left of the second pressure roller (i.e., its height is lower than the second pressure roller), the first pressure roller will first contact the left end face of the cigarette box in the conveying channel. As the cigarette box continues to be conveyed to the left, it will push the first pressure roller to gradually move to the left, causing the height of the second pressure roller to gradually decrease until the second pressure roller contacts the top surface of the cigarette box. At this point, the first pressure roller also contacts the top surface of the cigarette box. Using an elastic element, both the first and second pressure rollers can be pressed firmly onto the top surface of the cigarette box. Thus, after the second pressure roller presses the barcode affixed to the top surface of the cigarette box, the first pressure roller can press the barcode affixed to the top surface of the cigarette box again, thereby achieving two pressings of the barcode. This ensures that the barcode is firmly affixed to the cigarette box, effectively improving the quality of barcode adhesion on the cigarette box. Attached Figure Description

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0023] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0025] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0026] like Figures 1 to 3 As shown, this utility model embodiment provides a cigarette box barcode pressing device, which includes a support frame, a fixing plate 11, a first pressure roller 21, a second pressure roller 22, a first mounting frame, and a second mounting frame. The support frame is horizontally arranged across the conveying channel of the cigarette box conveying device. The fixing plate 11 is arranged on the support frame and located above the conveying channel. The upper end of the first mounting frame is rotatably connected to the fixing plate 11, and the first pressure roller 21 is rotatably arranged at the lower end of the first mounting frame. The upper end of the second mounting frame is rotatably connected to the fixing plate 11, and the second pressure roller 22 is rotatably arranged at the lower end of the second mounting frame. The first pressure roller and the second pressure roller are parallel, and the diameter of the first pressure roller is larger than the diameter of the second pressure roller. In its natural state, the first pressure roller 21 is located to the lower left of the second pressure roller 22. An elastic element is provided between the first mounting frame and the second mounting frame, and a limiting element for blocking contact with the second mounting frame is provided on the first mounting frame.
[0027] The cigarette box barcode pressing device provided in this embodiment of the utility model, when in use, since the first pressure roller is located to the lower left of the second pressure roller, that is, its height is lower than the second pressure roller, the first pressure roller will first contact the left end face of the cigarette box in the conveying channel. As the cigarette box is continued to be conveyed to the left, it will push the first pressure roller 21 to gradually move to the left, so that the height of the second pressure roller 22 gradually decreases until the second pressure roller contacts the top surface of the cigarette box. At this time, the first pressure roller also contacts the top surface of the cigarette box. The elastic element allows both the first pressure roller and the second pressure roller to be pressed firmly on the top surface of the cigarette box. In this way, after the second pressure roller presses the barcode pasted on the top surface of the cigarette box, the first pressure roller can press the barcode pasted on the top surface of the cigarette box again, thereby realizing the two-fold pressing of the barcode, so that the barcode can be firmly pasted on the cigarette box, effectively improving the pasting quality of the barcode on the cigarette box.
[0028] Furthermore, the first mounting frame includes a first rod 31, a second rod 32, and a connecting rod 33. The second rod is parallel to the first rod, and the first rod and the second rod are connected by the connecting rod 33. The upper ends of the first rod and the second rod are rotatably connected to the rotating shafts 12 provided at the front and rear ends of the fixed plate, respectively. The front and rear ends of the first pressure roller 21 are rotatably connected to the lower ends of the first rod and the second rod, respectively, through axles 23. This design simplifies the structure of the first mounting frame. In a specific embodiment, the connecting rod can preferably be positioned close to the first pressure roller.
[0029] Preferably, the second mounting bracket has the same structure as the first mounting bracket. It is understood that, as Figure 1 As shown, the second mounting bracket also includes the first rod, the second rod, and the connecting rod mentioned above. The difference is that, in this case, the front and rear ends of the second pressure roller 22 are rotatably connected to the lower ends of the first rod and the second rod via axle 23.
[0030] Specifically, both the first rod 31 and the second rod 32 of the first mounting bracket are provided with the aforementioned limiting members. These two limiting members effectively limit the first and second mounting brackets, maintaining a certain angle between them and preventing them from closing together. It is understood that the limiting member on the first rod of the first mounting bracket is used to abut against the first rod of the second mounting bracket, and the limiting member on the second rod of the first mounting bracket is used to abut against the second rod of the second mounting bracket.
[0031] Furthermore, the limiting member is a limiting plate 51, which has a limiting inclined surface for engaging with the second mounting bracket, thus simplifying the structure of the limiting member. Preferably, the limiting member is detachably connected to the first rod and the second rod, thereby facilitating replacement or maintenance of the limiting member.
[0032] Specifically, the elastic element is a tension spring 41, which simplifies the structure of the elastic element. Preferably, one end of the tension spring is connected to the middle of the connecting rod of the first mounting bracket, and the other end of the tension spring is connected to the middle of the connecting rod of the second mounting bracket.
[0033] In one embodiment, the support frame can be an inverted U-shaped frame composed of a horizontal bar and two vertical bars, with a fixing plate disposed on the horizontal bar.
[0034] Understandably, the first and second pressure rollers correspond to the barcode positions on the top surface of the cigarette box and are used to contact the barcode to press it firmly. In its natural state, the first pressure roller 21 is located to the lower left of the second pressure roller 22, that is, the first pressure roller is lower than the top surface of the cigarette box, and the second pressure roller is higher than the top surface of the cigarette box. The axial length of the two pressure rollers, i.e., their length in the axial direction, is determined according to the size of the barcode in the barcode pasting area of the cigarette box, so that the pressure rollers completely cover the barcode when the cigarette box passes by, ensuring the pressing effect and full pressing. The pressure rollers are cylindrical, and their outer layer can be a soft polyurethane layer to avoid damaging the cigarette box.
[0035] Since the upper ends of the first mounting bracket and the second mounting bracket of this application are rotatably connected to the fixed plate, and a tension spring 41 is connected between the first mounting bracket and the second mounting bracket, an automatic clamping device can be formed; the limiting member can make the first mounting bracket and the second mounting bracket have a certain angle in their natural state.
[0036] When the cigarette box conveying device transports the cigarette box to the first pressure roller, the left end face of the cigarette box pushes the first pressure roller. At this time, the tension spring is not under force and the resistance is minimal. When the second pressure roller touches the top surface of the cigarette box, the tension spring begins to stretch. As the cigarette box continues to be transported to the left, the tension spring is gradually stretched, and its tension gradually increases until the first pressure roller acts on the top surface of the cigarette box. As the cigarette box continues to move to the left, under the action of the tension spring, the first and second pressure rollers are always in close contact with the top surface of the cigarette box, and a certain clamping force is applied to the top surface of the cigarette box. The magnitude of the clamping force can be adjusted by changing the length and elastic coefficient of the tension spring, thereby using the first and second pressure rollers to achieve two-fold clamping of the barcode, making its adhesion more firm and reliable.
[0037] Compared with the prior art, the beneficial effects of this utility model are:
[0038] Since this device is installed on the cigarette box conveying device, as the cigarette box moves, this device can automatically flatten and press the barcodes affixed to the cigarette box without the need for other external force, which greatly saves manpower and reduces the cost of modification.
[0039] This device has a simple structure, low maintenance costs, and is not easily damaged; it can press the barcode affixed to the cigarette box twice.
[0040] This device will not cause the cigarette box to get stuck during use. Specifically, when the cigarette box moves to the device, it first pushes the first pressure roller 21 through its left end face. At this time, the tension spring is not under force and the resistance is minimal. When the second pressure roller 22 touches the top surface of the cigarette box, the tension spring begins to stretch, and its tension gradually increases until the first pressure roller 21 acts on the top surface of the cigarette box. Throughout the entire process, there is no sufficient external force to make the cigarette box reach a force balance, so it will not stop moving forward. Therefore, there will be no jamming of the cigarette box during the entire process.
[0041] This device is highly adaptable. Specifically, during the pressing process, when the second pressure roller 22 just touches the top surface of the cigarette box, it acts directly on the barcode pasted in the barcode pasting area of the cigarette box. The pressure gradually increases as the cigarette box moves to the left, preventing the barcode from shifting or flipping due to static friction. At the same time, it flattens the barcode, ensuring that the barcode is flat and free of air bubbles during subsequent pressing by the first pressure roller 21. Wrinkles, loose edges, and warping are less likely to occur during the pressing process. Furthermore, the double pressing by the first and second pressure rollers makes the barcode pasted on the cigarette box more firmly and reliably.
[0042] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
