Description

Technical Field

[0001] The utility model relates to the technical field of cigarette connecting and packaging machines, in particular to a glue circulation device for cigarette connecting and packaging machines. Background Art

[0002] The existing ZJ119 tipping machine's glue circulation system has been found to be subject to frequent wear and tear. This wear can lead to seal failure, causing glue leakage and air ingress, which can easily cause glue blistering and quality issues. This blistering can also cause glue breakage, uneven glue application, and improper tipping paper wrapping. Gear pump wear is particularly difficult to detect in its early stages, and during high-speed production, it can randomly produce a few thousandths of leaks and fumes, making them difficult to detect and detect. Furthermore, the gear pump's narrow installation location makes disassembly difficult, and its numerous parts and complex structure make disassembly and cleaning time-consuming, making it difficult to maintain a clean and tidy workstation. During gear pump disassembly, glue in the pipes can gradually leak out due to its own weight, making cleanup a hassle. Furthermore, insufficient sealing, insufficient mixing, and uneven glue flow can lead to bubbles in the glue, necessitating machine shutdown and draining. However, due to the different viscosities of spray glue and roller glue, the exhaust performance in actual use was less than satisfactory. Furthermore, as the equipment gradually wore out, the exhaust performance continued to decline, resulting in extended work hours and wasted glue. Furthermore, the ZJ119 is a high-speed machine, and its frequent starts and stops generate a large amount of exhaust smoke, resulting in significant waste of consumables. Therefore, it was urgent to optimize the ZJ119's glue system to address gear pump leakage and glue bubbles. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.

[0024] See also Figure 1 The present invention provides a glue circulation device for a cigarette assembling machine, comprising a glue roller 4, a glue barrel 1 for storing glue, a glue supply unit for conveying the glue in the glue barrel 1 to the glue roller 4, and a glue return unit for receiving excess glue flowing out of the glue roller 4 and conveying it to the glue supply unit. The glue roller 4 is used to glue tobacco tipping paper. The glue supply unit comprises a first magnetic pump 2, a first conveying structure having two ends respectively connected to one end of the glue barrel 1 and one end of the first magnetic pump 2, and a second conveying structure having one end connected to the other end of the first magnetic pump 2 and the other end disposed close to the glue roller 4.

[0025] Here, the glue supply components are connected in series in the following order: glue drum 1 - first conveying structure - first magnetic pump 2 - second conveying structure. The glue in glue drum 1 is qualified glue and requires timely replacement and refilling by staff. The glue flows out of glue drum 1 and is transported to first magnetic pump 2 via the first conveying structure. The glue in first magnetic pump 2 is then transported to gluing roller 4 via the second conveying structure. This gluing roller 4 applies glue to the tobacco tipping paper. Excess glue flows onto gluing roller 4. The glue return component receives this excess glue and transports it to the glue supply component, allowing it to continue supplying glue to gluing roller 4, recycling the glue and improving glue utilization.

[0026] Specifically, the first magnetic suction pump 2 mainly uses the action of magnetic force to drive the blades inside the pump body, changing the original gear pump's axial dynamic seal to a static seal, effectively avoiding problems such as glue leakage, loud noise, and poor interchangeability caused by long-term friction and wear of the axial dynamic seal.

[0027] The first conveying structure may include a debubbler 51 for removing bubbles in the glue, a first liquid outlet 511 arranged at the bottom of the debubbler 51, and a first conveying pipe 53 with one end connected to the first liquid outlet 511 and the other end connected to the first magnetic suction pump 2.

[0028] Specifically, the debubbler 51 adopts a vacuum debubbling method. After the glue enters the debubbler 51, the bubbles inside will float to the surface of the glue due to the negative pressure, then burst and be absorbed by the negative pressure, thereby achieving the purpose of debubbling.

[0029] A first liquid inlet 512 may be provided at the top of the debubbler 51, and the first conveying structure further includes a first filter 52 for filtering the glue, a second conveying pipe 54 whose two ends are respectively connected to the glue barrel 1 and one end of the first filter 52, and a third conveying pipe 55 whose two ends are respectively connected to the other end of the first filter 52 and the first liquid inlet 512.

[0030] Specifically, a first filter 52 is installed in the glue supply to filter out impurities such as unprocessed solid particles or newly formed lumps in the glue. The first filter 52 can include a first filter screen or a first filter element 521. The first filter screen or first filter element 521 needs to be cleaned or replaced periodically to prevent glue impurities from clogging the first filter 52 and preventing glue from being discharged.

[0031] The glue barrel 1 may include a barrel body 11 , a delivery pipe 12 connected to the bottom of the barrel body 11 , and an angle seat valve 13 disposed on the delivery pipe 12 . One end of the first delivery pipe 53 is connected to the delivery pipe 12 .

[0032] Specifically, when glue needs to be added, the angle seat valve 13 is opened, and the glue flows out of the glue barrel 1 under the influence of the negative pressure environment of the debubble device 51 , passes through the first filter 52 , and enters the debubble device 51 .

[0033] A second liquid inlet 513 may be provided on the top of the debubbler 51 , and one end of the glue return member is connected to the second liquid inlet 513 .

[0034] The glue return part can include a second magnetic pump 6, a fourth delivery pipe 82, and a third delivery structure. One end of the fourth delivery pipe 82 is used to receive excess glue flowing out of the glue coating roller 4, and the other end is connected to one end of the second magnetic pump 6. One end of the third delivery structure is connected to the other end of the second magnetic pump 6, and the other end is connected to the second liquid inlet 513.

[0035] Specifically, the second magnetic suction pump 6 mainly uses the action of magnetic force to drive the blades inside the pump body, changing the original gear pump's axial dynamic seal to a static seal, effectively avoiding problems such as glue leakage, loud noise, and poor interchangeability caused by long-term friction and wear of the axial dynamic seal.

[0036] The third conveying structure may include a second filter 81, a fifth conveying pipe 83, and a sixth conveying pipe 84. One end of the fifth conveying pipe 83 is connected to the other end of the second magnetic pump 6, and the other end is connected to one end of the second filter 81. One end of the sixth conveying pipe 84 is connected to the other end of the second filter 81, and the other end is connected to the second liquid inlet 513.

[0037] Specifically, a second filter 81 is installed in the glue return unit to filter out impurities such as unprocessed solid particles or newly produced lumps in the glue. Second filter 81 can include a second filter screen or a second filter element, which needs to be cleaned or replaced periodically to prevent glue impurities from clogging second filter 81 and preventing glue from being discharged.

[0038] The first conveying structure can also include multiple first manual ball valves 56 respectively arranged on the first conveying pipe 53, the second conveying pipe 54, and the third conveying pipe 55. The second conveying structure can include a seventh conveying pipe 57 and a third manual ball valve 85 arranged on the seventh conveying pipe 57. One end of the seventh conveying pipe 57 is connected to the other end of the first magnetic suction pump 2, and the other end is used to convey the glue to the glue coating roller 4.

[0039] The rubber return member may further include a plurality of third manual ball valves 85 respectively provided on the fourth delivery pipe 82 , the fifth delivery pipe 83 , and the sixth delivery pipe 84 .

[0040] The first control structure 3 and the second control structure 7 are both servo motors.

[0041] Specifically, a magnetic pump is used as the power source for pumping glue. A servo motor controls the first magnetic pump 2, and another servo motor controls the second magnetic pump 6. The servo motor can start and stop immediately. The servo motor can be controlled to control the magnetic pump, thereby controlling the amount of glue used.

[0042] The first conveying structure further includes a gravity sensor 59 for weighing the debubbler 51 .

[0043] Specifically, a gravity sensor 59 is mounted at the lower end of the debubble remover 51. This sensor detects the real-time weight of the debubble remover 51. If the real-time weight is less than a first preset weight, it indicates insufficient glue in the debubble remover 51. When this occurs, a signal is generated, causing the angle seat valve 13 to open and refill the glue. The debubble remover 51 also includes a support platform. The gravity sensor 59 is mounted on the top surface of the support platform. When the debubble remover 51 is placed on the support platform, the gravity sensor 59 can weigh the debubble remover 51. The gravity sensor 59 is a device that converts the acceleration caused by gravity into a voltage output. By measuring the acceleration caused by gravity, the device's tilt angle relative to the horizontal plane can be calculated, thereby indirectly measuring weight. The operating principle of the gravity sensor 59 is based on the piezoelectric effect. This is because applying an external force to a heteropolar crystal without a center of symmetry not only causes the crystal to deform, but also changes its polarization state, establishing an electric field within the crystal. This phenomenon of polarization of a medium by mechanical force is known as the positive piezoelectric effect. The gravity sensor 59 utilizes the internal crystal deformation characteristics caused by acceleration, measures the deformation and converts it into voltage output using relevant circuits, thereby achieving weight measurement.

[0044] Specifically, the entire working process is as follows: first, glue is poured into the glue barrel 1. Then, all of the first, second, and third manual ball valves 56, 58, and 85 are opened to evacuate the debubble chamber 51. Next, the angle seat valve 13 is opened, and the glue flows out of the glue barrel 1 under negative pressure. The glue first passes through the first filter 52, which traps lumps and other solid impurities in the glue. Glue that meets the requirements flows out of the outlet of the first filter 52 and enters the debubble chamber 51. The debubble chamber 51 removes bubbles from the glue, and then flows out from the bottom into the first magnetic pump 2. Finally, it flows into the glue roller 4 to glue the tobacco tipping paper. Excess glue in the glue roller 4 is pumped out by the second magnetic pump 6, passes through the second filter 81, and returns to the debubble chamber 51.
