Description

Technical Field

[0001] This application relates to the field of cigarette packaging equipment technology, and more particularly to a trademark conveying device. Background Technology

[0002] Packaging machines are a commonly used piece of equipment in tobacco production. By packaging and sealing finished tobacco products, they improve production efficiency and ensure product quality.

[0003] Currently, existing packaging machines use a roller conveyor system for conveying the glued label paper as it descends, with a further acceleration roller system at the end of the conveying process to ensure the label paper can be smoothly transported to the next processing stage. However, in actual use, this conveying method has certain drawbacks, significantly impacting product quality and production efficiency.

[0004] Specific defects include: high frequency of downtime due to malfunctions, high frequency of maintenance, and poor quality stability. The reasons for these defects are: the existing descent conveyor components have high requirements for the adaptability of label paper to the machine, making it difficult to consistently guarantee conveying stability and easily producing defective products; the accelerated conveying at the end of the existing descent conveyor has an impact, causing rebound, resulting in misalignment of the label paper overlap and distorted patterns; the existing descent conveyor's two-point pressure roller conveying system causes the label paper to be twisted under force, resulting in adhesive contamination of the conveying channel, leading to short cleaning and maintenance cycles, difficulty in meeting continuous production needs, and a tendency to produce quality defects such as misaligned label paper and damaged cigarette packs.

[0027] The existing packaging machine uses a roller conveyor system for conveying the glued label paper after it has been coated, with a further acceleration roller system at the end of the conveying process to ensure the label paper can be smoothly transported to the next processing stage. However, in actual use, this conveying method has certain drawbacks, significantly impacting product quality and production efficiency. Specific drawbacks include: high frequency of downtime due to malfunctions, high maintenance frequency, and poor quality stability. These drawbacks are caused by: the existing conveyor system's high adaptability to the label paper, difficulty in consistently maintaining conveying stability, and a tendency to produce defective products; the acceleration at the end of the existing conveyor system causes impact and rebound, leading to misalignment of the label paper overlap and distorted patterns; and the existing two-point roller conveying system causes the label paper to twist under stress, resulting in glue contamination of the conveying channel, short cleaning and maintenance cycles, difficulty in meeting continuous production needs, and a tendency to produce quality defects such as misaligned labels and damaged cigarette packs.

[0028] To address the aforementioned issues, this application provides a trademark conveying device that solves the problems of existing devices and improves the conveying stability and production efficiency of trademark paper.

[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] See Figure 1-14 A trademark conveying device includes: a negative pressure conveying mechanism 10 and a positive pressure conveying mechanism 20, wherein the positive pressure conveying mechanism 20 is disposed at the bottom position of the negative pressure conveying mechanism 10; The negative pressure conveying mechanism 10 includes: a first negative pressure mounting plate 101, a second negative pressure mounting plate 102, a drive gear assembly 103, a driven gear assembly 104, a pulley assembly 105, and a negative pressure suction device.

[0032] The first negative pressure mounting plate 101 is hingedly mounted on the second negative pressure mounting plate 102; like Figure 8 As shown, two suction grooves 1011 are provided on the first negative pressure mounting plate 101, and suction holes 1012 connected to the suction grooves are provided on the side wall of the first negative pressure mounting plate. Specifically, suction baffles 1013 are provided on both sides of the suction trough to enhance the negative pressure adsorption force.

[0033] The suction baffle 1013 can form a more enclosed space on the surface of the pulley, which helps to enhance the negative pressure adsorption force by reducing airflow leakage, improve the adsorption effect, and ensure that the label paper is firmly adhered to the conveying device.

[0034] The active gear assembly 103 is mounted on the top of the second negative pressure mounting plate 102, and the driven gear assembly 104 is mounted on the top of the first negative pressure mounting plate 101. The active gear assembly 103 is driven to rotate the driven gear assembly 104. Specifically, the drive gear assembly 103 includes: a bearing support 1031, a first shaft 1032, a coupling 1033, a drive gear 1034, and a handwheel 1035; the bearing support 1031 is mounted on the top of the second negative pressure mounting plate 102, and two bearings are mounted on the bearing support 1031; the first shaft 1032 is mounted in the bearing support 1031, and the first shaft 1032 passes through the bearings on the bearing support 1031; the coupling 1033 is mounted at the front end of the first shaft 1032, the drive gear 1034 is mounted at the front end of the first shaft 1032, and the handwheel 1035 is mounted at the rear end of the first shaft 1032; Specifically, the driven gear assembly 104 includes: a first bearing housing 1041, a second bearing housing 1042, a second shaft 1043, and a driven gear 1044; the first bearing housing 1041 and the second bearing housing 1042 are mounted on the top of the first negative pressure mounting plate 101, the second shaft 1043 is mounted on the first bearing housing 1041 and the second bearing housing 1042, and the driven gear 1044 is mounted at the front end of the second shaft 1043.

[0035] like Figure 3 As shown, after installation, the driving gear and driven gear mesh with each other and can be connected to an external drive motor bearing via a coupling to drive the driving gear to rotate. Driving the driven gear with the driving gear ensures more stable operation of the conveying device, helping to reduce vibration and noise problems caused by transmission instability. Furthermore, the transmission systems between the driving and driven gears are relatively independent, facilitating maintenance and repair.

[0036] The pulley assembly 105 includes: two sets of synchronous pulleys, which are mounted on the first negative pressure mounting plate 101 and are driven to move synchronously by the driven gear assembly 104; the belts of the two sets of synchronous pulleys are provided with suction holes, and the belts are positioned above the suction groove. Specifically, the synchronous pulley includes a pulley and a belt; one pulley is mounted on a second shaft, and the other pulley is mounted on a bearing seat on top of a first positive pressure mounting plate.

[0037] After the pulley assembly is installed, the pulley will rotate together with the driven gear. By controlling the direction of movement, the belt can move downwards.

[0038] The negative pressure suction device is connected to the suction hole through a pipe. By driving the negative pressure suction device to draw air, a negative pressure suction is generated at the suction hole. The label paper is then conveyed downwards along the belt by negative pressure adsorption.

[0039] This negative pressure suction device is a vacuum pump. After being connected to all the suction holes on the first negative pressure mounting plate through a pipe, the vacuum pump is driven to draw air, which can generate negative pressure inside the suction slot. This creates negative pressure suction at the suction holes on the pulley, adsorbing the label paper. At the same time, the downward movement of the belt causes the label paper to be transported down with the belt, thus achieving the transport of the label paper by negative pressure adsorption.

[0040] This method of conveying label paper through negative pressure adsorption provides flexible constraints during the conveying process, making it less prone to shifting or displacement and resulting in more stable conveying. At the same time, it avoids the problem of glue accumulation caused by contact between glue dots and pressure rollers or guide grooves, which is common in conveying methods using pressure rollers and conveyor rollers. This helps reduce the frequency of equipment cleaning and maintenance and improves production efficiency.

[0041] The positive pressure conveying mechanism 20 includes: a first positive pressure mounting plate 201, a second positive pressure mounting plate 202, and a positive pressure blower; The first positive pressure mounting plate 201 is installed at the bottom of the first negative pressure mounting plate 101, and the first positive pressure mounting plate 201 is provided with an air blowing hole 2011 and an air blowing guide groove 2012. The positive pressure blower is connected to the air blowing hole through a pipe. By driving the positive pressure blower to blow air, positive pressure is generated at the position of the air blowing guide groove. The label paper is then conveyed downwards by positive pressure air guiding. A stop baffle 2021 is provided on the second positive pressure mounting plate 202. Specifically, an oblique jet hole 2013 is provided at the outlet position of the air blowing hole to guide the direction of air output.

[0042] The 2013 angled jet orifice is a downward-sloping angled orifice. The angled jet orifice design can make the airflow more concentrated and directional, improve the blowing efficiency, ensure that the label paper receives appropriate airflow support during the conveying process, and improve the conveying efficiency.

[0043] The positive pressure blower is an air pump. After being connected to all the air holes on the first positive pressure mounting plate 201 through pipes, the air pump is driven to inflate the paper, generating positive pressure at the outlet of the air holes. Simultaneously, by setting oblique jet holes and air guide channels, the airflow is directed towards the oblique jet holes and flows through the air guide channels. After the label paper is conveyed to the bottom by the negative pressure conveying mechanism, it continues to move downwards under the positive pressure of the air guide channels, stopping at the stop baffle 2021 on the second positive pressure mounting plate 202. This completes the downward conveying process of the label paper, awaiting the next operation by the inward moving mechanism.

[0044] This positive pressure air-guided conveying method is gentler. The label paper is pushed by a uniform airflow during the conveying process, which can avoid the label paper from colliding with the paper receiving hopper, causing the label paper to wrinkle or bounce. At the same time, the positive pressure air-guided method, combined with the design of inclined jet holes and air blowing guide grooves, allows the airflow to flow in the set direction, thereby realizing the continuous conveying of the label paper, improving positioning accuracy, and ensuring production efficiency and stability.

[0045] Specifically, such as Figure 1 As shown in the embodiments of this application: The trademark conveying device also includes: a first sliding support plate 30 and a second sliding support plate 40; The first sliding bracket plate 30 is provided with a first sliding table 301, and the second negative pressure mounting plate 102 is mounted on the first sliding table 301. The second sliding bracket plate 40 and the second positive pressure mounting plate 202 are mounted on the second sliding bracket plate 40.

[0046] The trademark conveying device of this application is installed on the existing packaging unit via the first sliding support plate 30 and the second sliding support plate 40. Simultaneously, by installing the second negative pressure mounting plate 102 on the first slide table 301 and fixing it via the first sliding support plate 30, the negative pressure conveying mechanism can slide along the first slide table on the first sliding support plate. This facilitates maintenance, daily cleaning, and upkeep of the negative pressure conveying mechanism, saving time and effort and improving reliability.

[0047] Specifically, such as Figure 7 and Figure 9 As shown in the embodiments of this application: The first negative pressure mounting plate 101 is equipped with two sets of tightening guide wheel assemblies 50; The tightening guide wheel assembly 50 includes: a guide wheel base 501, a guide wheel support rod 502, and a guide wheel 503; The guide wheel base 501 is mounted on the front wall of the first negative pressure mounting plate 101; The guide wheel support rod 502 is mounted on the guide wheel base 501; The guide wheel 503 is mounted on the guide wheel support rod 502 and is located above the belt.

[0048] By setting the tensioning guide wheel assembly 50, the tension of the pulley can be adjusted, which can effectively improve the stability and reliability of the belt during the negative pressure adsorption process, reduce problems caused by belt loosening or falling off, and ensure the stability of negative pressure adsorption.

[0049] Specifically, such as Figure 6 As shown in the embodiments of this application: A guide plate 106 is installed on the top of the first negative pressure mounting plate 101; A guide plate 107 is mounted on the first shaft 1032.

[0050] By setting up the guide disc 107, when the drive gear rotates, the guide disc 107 can rotate together with the first shaft 1032, which can better guide and drive the label paper into the negative pressure conveying mechanism for conveying. At the same time, by setting up the guide plate 106, the conveyed label paper can be limited to prevent it from deviating during the conveying process, ensuring the stability and accuracy of the conveying. The design of the guide disc 107 and the guide plate 106 can improve the stability of the entire conveying system, ensuring that the label paper can smoothly and stably enter and pass through the negative pressure conveying mechanism, thereby improving production efficiency and quality.

[0051] Specifically, such as Figure 6 and Figure 14 As shown in the embodiments of this application: The second negative pressure mounting plate 102 is equipped with a first guide bracket 108; by setting the first guide bracket 108, the trademark paper can be limited during the process of conveying the trademark paper by negative pressure adsorption, so as to ensure the stability of the conveying.

[0052] A second guide bracket 2022 is installed on the second positive pressure mounting plate 202; By setting a second guide bracket 2022, the label paper can be limited during the positive pressure air conveying process, ensuring the stability of the conveying.

[0053] Specifically, such as Figure 6 , Figure 13 , Figure 11 As shown in the embodiments of this application: The second negative pressure mounting plate 102 is equipped with a release guide wheel assembly 1021; the release guide wheel assembly 1021 is a roller rod. By setting the release guide wheel assembly 1021, when the label paper enters the positive pressure conveying mechanism, the label paper can be limited and the label paper can be stably entered into the positive pressure conveying mechanism.

[0054] The second positive pressure mounting plate 202 is equipped with a paper door guide wheel assembly 2014; By setting the paper door guide roller assembly 2014, the stability of the conveying process can be improved during the positive pressure air conveying of the trademark paper, and the next inward pushing operation can be facilitated.

[0055] An auxiliary guide wheel assembly 1022 is installed on the second negative pressure mounting plate 102; The auxiliary guide wheel assembly 1022 is a roller. By setting the auxiliary guide wheel assembly 1022, the sliding stability can be improved when the first sliding support plate 30 slides.

[0056] Specifically, in the embodiments of this application: Both the negative pressure conveying mechanism 10 and the positive pressure conveying mechanism 20 are equipped with door lock devices 60; The door lock device 60 includes a hook 601, a first hook support 602, and a second hook support 603. The hook 601 is hingedly mounted on the first hook support 602, and can be fixed to the second hook support 603 by rotating the hook 601.

[0057] By setting the door lock device 60, the negative pressure conveying mechanism and the positive pressure conveying mechanism can be kept closed to prevent accidental opening during operation, avoid potential safety hazards and production accidents, and ensure the normal operation of the conveying work.

[0058] The embodiments of this application include the following beneficial effects: This application provides a negative pressure conveying mechanism 10, which can convey the label paper by negative pressure adsorption. This provides flexible constraints for the label paper during the conveying process, making it less likely for the label paper to shift or move during the conveying process, thus making the conveying more stable. At the same time, it can avoid the problem of glue accumulation caused by the contact between glue dots and pressure rollers or guide grooves in the conveying method of pressure rollers and conveying rollers, which helps to reduce the frequency of equipment cleaning and maintenance and improve production efficiency.

[0059] This application, by setting a positive pressure conveying mechanism 20, ensures that the label paper is pushed by a uniform airflow during the conveying process, which can prevent the label paper from colliding with the paper receiving hopper and causing the label to wrinkle or bounce. At the same time, the positive pressure air guiding method, combined with the design of the inclined jet hole and the air blowing guide groove, allows the airflow to flow in the set direction, ensuring the efficiency and stability of production.
