Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco processing equipment, specifically to a steering and conveying mechanism for the label paper supply system of a YB28 soft box packaging machine. Background Technology
[0002] In the label paper supply system of the YB28 flexible packaging machine, the flexible label paper (also known as cigarette box packaging paper or cigarette pack packaging paper) is conveyed to the label paper buffer device after being unwound. The negative pressure suction pipe inside the buffer device ensures that a certain amount of flexible label paper is always stored within it, guaranteeing a continuous and stable supply and preventing problems such as supply interruption, accumulation, or unstable tension. Finally, it is conveyed to the label paper cutting equipment for subsequent cutting. Due to the internal space limitations of the packaging machine and the layout limitations of the flexible label paper conveying and cutting processes, the flexible label paper needs to undergo two 90-degree turns during its conveyance from the buffer device to the cutting device (see...). Figure 1 In the following application documents, we will refer to the soft box label paper as the label paper.
[0003] Traditional conveying methods rely on ordinary guide rollers to guide the label paper to different directions. However, these conventional guide rollers have significant drawbacks at this station. Ordinary guide rollers cannot adjust the tension of the label paper. During the two turns of the label paper, the complex path easily leads to uneven tension. When the label paper is too loose, it is prone to wrinkles and misalignment during conveying, causing it to pile up and tangle at the turning points, resulting in blockages. This also leads to inaccurate cutting positions, affecting the appearance quality of the finished package. Conversely, when the tension is too tight, the friction between the label paper and the guide rollers increases dramatically. This accelerates component wear, and excessive tension can deform the label paper, again leading to inaccurate cutting positions. Furthermore, localized stress concentration can cause the label paper to tear, ultimately affecting the smoothness of the packaging process and causing a series of problems such as blockages. Once a blockage occurs, the entire packaging production line will be forced to stop, requiring significant time and manpower for cleaning and adjustments, greatly reducing production efficiency, increasing production costs, and causing considerable inconvenience and losses for the company.
[0004] Furthermore, in actual production, it is often necessary to change to different suppliers and materials for the label paper. Due to the differences in their physical properties, different labels require vastly different tensions. These differences make it increasingly difficult for ordinary guide rollers with fixed tension to meet production demands, further exacerbating the instability in the label paper conveying process and frequently causing problems such as blockages and inaccurate cutting, seriously affecting packaging quality and production efficiency.
[0005] In summary, to meet the high-efficiency and stable label paper conveying requirements of the YB28 flexible box packaging machine, it is urgent to develop a new type of turning conveying mechanism that can effectively solve the tension adjustment problem during label paper turning conveying and avoid blockage.

[0007] To solve the above problems and achieve the above objectives, the present invention adopts the following technical solution:

[0009] The first guide roller (1) is connected to the body (4) of the YB28 soft box packaging machine;
[0010] The second guide roller (2) is connected to the body (4) of the YB28 soft box packaging machine and is below the first guide roller (1);
[0011] Adjustable tension roller assembly (3), which is detachably connected to the first paper guide roller (1), can rotate on the first paper guide roller (1) and be locked in place.
[0012] As a preferred embodiment of this utility model, the adjustable tension roller assembly (3) includes:
[0013] Roller seat (31), the roller seat (31) is detachably connected to the first paper guide roller (1), can rotate on the first paper guide roller (1) and be locked and fixed, and the roller seat (31) has a threaded hole for connecting the shaft (32);
[0014] Shaft (32), one end of the shaft (32) has a threaded rod and the other end has an internal thread. One end is detachably connected to the roller seat (31) through the threaded rod and hexagonal nut (321), and the other end is detachably connected to the body (4) of the YB28 soft box packaging machine through the internal thread and bolt.
[0015] A roller (33) is connected to a shaft (32) and can rotate on the shaft (32).
[0016] As a preferred embodiment of the present invention, the roller seat (31) is formed by a first clamping body (311) and a second clamping body (312) fixedly connected.
[0017] As a preferred embodiment of this utility model, the first clamping body (311) has a bolt hole (3111) and the second clamping body (312) has a countersunk screw hole (3121). After the locking bolt (313) passes through the countersunk screw hole (3121) and the bolt hole (3111) in sequence and is tightened, the roller seat (31) and the adjustable tension roller assembly (3) can be locked and fixed on the first paper guide roller (1).
[0018] The working principle of this utility model mainly includes:
[0019] 1. The functions of the first guide roller (1) and the second guide roller (2):
[0020] The first guide roller (1) and the second guide roller (2) are respectively connected to the body (4) of the YB28 soft box packaging machine. They are responsible for guiding the label paper (5) forward on the conveying path, realizing the label paper (5) being conveyed by two 90-degree turns in the label paper buffer device (6) and the label paper cutting device (7).
[0021] 2. Structural design of adjustable tension roller assembly (3):
[0022] The adjustable tension roller assembly (3) is detachably connected to the first guide roller (1). Its structural design allows for rotation and locking on the first guide roller (1) to accommodate different tension requirements of the trademark paper (5).
[0023] Specifically, the adjustable tension roller assembly (3) includes a roller seat (31), a shaft (32), and a roller (33).
[0024] Roller seat (31): The roller seat (31) is formed by a first clamping body (311) and a second clamping body (312) fixedly connected, and is detachably connected to the first guide roller (1). By tightening the bolt holes (3111) on the first clamping body (311) and the countersunk screw holes (3121) on the second clamping body (312), as well as the locking bolts (313), the roller seat (31) and the entire adjustable tension roller assembly (3) can be locked and fixed to a specific position and direction on the first guide roller (1).
[0025] Shaft (32): One end of shaft (32) has a threaded rod, which is detachably connected to roller seat (31) via the threaded rod and hexagonal nut (321); the other end has an internal thread, which is detachably connected to the body (4) of YB28 soft box packaging machine via the internal thread and bolt. This design allows shaft (32) and roller (33) to be installed and positioned on roller seat (31).
[0026] Roller (33): The roller (33) is connected to the shaft (32) and can rotate on the shaft (32) so as to contact the label paper (5) and apply appropriate tension to it.
[0027] 3. Tension adjustment (see...) Figure 3 — Figure 6 ):
[0028] The tension of the trademark paper (5) can be adjusted by adjusting the position and angle of the adjustable tension roller assembly (3) on the first guide roller (1).
[0029] When the tension of the trademark paper (5) is too loose, the tension of the trademark paper (5) can be increased by rotating the angle of the roller seat (31) and locking it, thus avoiding problems such as wrinkles, deviations, and inaccurate subsequent cutting positions.
[0030] When the tension of the trademark paper (5) is too tight, the angle of the roller seat (31) can be adjusted and locked in the opposite way to reduce the tension of the trademark paper (5) and avoid problems such as the trademark paper (5) being stretched or damaged, and inaccurate subsequent cutting position.
[0031] The beneficial effects of this utility model are:
[0032] 1. This invention significantly improves the stability and adaptability of label paper conveying: By introducing an adjustable tension roller assembly, this invention enables the adjustment of the label paper's tension, avoiding problems such as wrinkles, offsets, stacking, and tangling caused by uneven tension during conveying, thus ensuring smooth conveying of the label paper and improving its conveying stability. Furthermore, it can be adjusted to accommodate different label paper suppliers and materials, resulting in varying required tension levels, thereby enhancing the adaptability of label paper conveying.
[0033] 2. This utility model improves the appearance quality of finished packaging products: Since this utility model can ensure the flatness and accuracy of the label paper during the transportation process, it can effectively avoid the problem of inaccurate positioning of the label paper during cutting, thereby improving the appearance quality of finished packaging products.
[0034] 3. This utility model improves production efficiency and reduces production costs: Since this utility model can effectively avoid problems such as blockage of label paper during the transportation process, it can ensure the smooth operation of the packaging production line, avoid production line interruption and cleaning and debugging time caused by blockage, thereby improving production efficiency and reducing production costs.

Detailed Implementation
[0047] To make the purpose, technical solution and advantages of this utility model patent clearer, the present utility model patent will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model patent. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of this utility model patent.
[0048] Example 1
[0049] In this embodiment, the required components are prefabricated in the factory and then processed according to... Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 11 Complete assembly and installation.
[0050] like Figure 1 — Figure 11 The illustrated YB28 flexible box packaging machine label paper supply system steering conveyor mechanism is located downstream of the YB28 flexible box packaging machine label paper buffer device 6 and upstream of the label paper cutting device 7. It includes:
[0051] The first paper guide roller 1 is connected to the body 4 of the YB28 flexible box packaging machine;
[0052] The second guide roller 2 is connected to the body 4 of the YB28 soft box packaging machine and is located below the first guide roller 1.
[0053] Adjustable tension roller assembly 3 is detachably connected to the first paper guide roller 1, and can rotate on the first paper guide roller 1 and be locked in place.
[0054] Furthermore, such as Figure 8 — Figure 11 As shown, the adjustable tension roller assembly 3 includes:
[0055] Roller seat 31, which is detachably connected to the first paper guide roller 1, can rotate on the first paper guide roller 1 and be locked and fixed, and has a threaded hole for connecting to shaft 32;
[0056] Shaft 32, one end of which has a threaded rod and the other end has an internal thread. One end is detachably connected to roller seat 31 through the threaded rod and hexagonal nut 321, and the other end is detachably connected to the body 4 of YB28 soft box packaging machine through the internal thread and bolt.
[0057] Roller 33 is connected to shaft 32 and can rotate on shaft 32.
[0058] Furthermore, such as Figure 10 As shown, the roller seat 31 is formed by a first clamping body 311 and a second clamping body 312 fixedly connected.
[0059] Furthermore, such as Figure 10 , Figure 11As shown, the first clamping body 311 has bolt holes 3111, and the second clamping body 312 has countersunk screw holes 3121. After the locking bolts 313 are passed through the countersunk screw holes 3121 and the bolt holes 3111 in sequence and tightened, the roller seat 31 and the adjustable tension roller assembly 3 can be locked and fixed on the first paper guide roller 1.
[0060] In summary, the specific usage process of this utility model is as follows:
[0061] First, such as Figure 1 , Figure 2 As shown, the adjustable tension roller assembly 3 is adjusted to a relatively suitable initial position, and then the equipment is started for debugging. The operator observes the state of the label paper 5 as it is conveyed from the label paper buffer device 6 to the cutting device 7.
[0062] If wrinkles appear on the surface of the label paper 5, especially if the wrinkles increase significantly at the turning points of the first guide roller 1 and the second guide roller 2, it indicates that the tension of the label paper 5 is too loose. At this time, the label paper 5 may also be accompanied by edge wobbling, deviation, or even a tendency to stack or entangle at the turning points. The operator should stop the machine immediately.
[0063] After shutdown, as Figure 5 , Figure 6 As shown, by loosening the locking bolt 313 and rotating the roller seat 31, its angle is adjusted in the direction of increasing the tension of the 5 sheets of trademark paper. After the adjustment is completed, the locking bolt 313 is tightened again, and the equipment is restarted to observe the status of the trademark paper conveying until problems such as wrinkles, offsets, and inaccurate subsequent cutting positions are eliminated.
[0064] Conversely, if it is observed that the label paper 5 is too tight during the conveying process and there are signs of stretching and deformation at the edges, it indicates that the tension of the label paper 5 is too high, and the operator should also stop the machine.
[0065] After shutdown, as Figure 3 , Figure 4 As shown, loosen the locking bolt 313, rotate the roller seat 31 in the opposite direction to adjust its angle in the direction of reducing the tension of the label paper 5. After adjustment, tighten the locking bolt 313 again, start the equipment again and observe the label paper conveying status until problems such as the label paper 5 being stretched or damaged, or inaccurate subsequent cutting positions are eliminated.
[0066] When changing to a different label paper 5, or when the label paper 5 conveying malfunctions again, repeat the above process until the tension is adjusted to the appropriate value and the conveying problem is eliminated.
[0067] Finally, it should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
