Description

Technical Field

[0001] The utility model relates to the technical field of tobacco tipping machines, in particular to a glue supply transmission device for a tobacco tipping machine. Background Art

[0002] Currently, the glue circulation system for the ZJ119 tobacco packaging machine primarily uses a gear pump. This pump pumps transfer liquids by utilizing the displacement and movement of the pump cylinder and meshing gears. Two gears, the pump body, and the front and rear covers form two enclosed chambers. As the gears rotate, the volume of the chamber on the disengaged side expands, creating a vacuum that draws the glue in. The volume of the chamber on the meshed side contracts, squeezing the glue into the pipeline. During operation, the gear pump's shaft interfaces with the motor, and a dynamic seal is used between the shaft and the pump body to seal the internal cavity. This seal is prone to failure and leakage. In particular, when the gear blades encounter crusted and clumped glue, the gear pump generates radial force imbalance and high flow pulsation. Long-term radial force imbalance and flow pulsation exacerbate gear pump wear. Mechanical wear leads to high noise levels, low efficiency, poor component interchangeability, difficulty repairing worn parts, and lubricant ingress and contamination of the glue.

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figures 1 to 2 The embodiment of the present invention is a glue supply transmission device for a cigarette assembling machine, comprising a magnetic suction pump 4, a glue storage tank 1 for storing glue, a first conveying member having two ends respectively connected to the input end of the magnetic suction pump 4 and one end of the glue storage tank 1, a second conveying member connected to the output end of the magnetic suction pump 4, and a first controller for controlling the magnetic suction pump 4.

[0024] Here, an appropriate amount of glue is stored in the glue storage tank 1, and the glue storage tank 1, the first conveying member, the magnetic pump 4, and the second conveying member are connected in series in sequence. The first controller controls the magnetic pump 4 so that the glue flows out of the glue storage tank 1 under pressure, and is conveyed to the magnetic pump 4 through the first conveying member. The glue in the magnetic pump 4 flows out through the second conveying member, thereby solving the problems of the existing cigarette connecting machine glue supply transmission system using a gear pump, which causes high noise, low efficiency, poor interchangeability of parts, difficulty in repair after wear, and lubricating oil entering and contaminating the glue.

[0025] The first controller is a servo motor 41 connected to the magnetic pump 4 .

[0026] Specifically, the magnetic pump 4 is controlled by a servo motor 41, which can be started and stopped instantly. By controlling the servo motor 41, the magnetic pump 4 can be controlled, thereby controlling the glue dosage. The magnetic pump 4 primarily utilizes magnetic force to drive the blades within the pump body, replacing the original gear pump's dynamic shaft seal with a static seal. This effectively avoids problems such as glue leakage, high noise, and poor interchangeability caused by long-term friction and wear of the dynamic shaft seal.

[0027] The glue supply transmission device of the cigarette bottling machine in this embodiment may further include a weighing element for weighing the glue storage tank 1 .

[0028] Specifically, the glue storage tank 1 without glue and the glue storage tank 1 filled with glue are weighed respectively by a weighing device, so that the weight of the glue in the glue storage tank 1 can be obtained, so that glue can be added to the glue storage tank 1 according to the actual weight of the glue, or the first glue storage tank 1 with insufficient glue can be replaced with a second glue storage tank 1 containing glue of appropriate weight.

[0029] The first conveying member may include a filter 3 for filtering glue, a first conveying pipe 51 whose two ends are respectively connected to one end of the filter 3 and the bottom of the glue storage tank 1, a second conveying pipe 52 whose two ends are respectively connected to the input end of the magnetic pump 4 and the other end of the filter 3, and the second conveying member includes a third conveying pipe 53 connected to the output end of the magnetic pump 4.

[0030] Specifically, one end of the first delivery pipe 51 is detachably connected to the bottom of the glue storage tank 1, and the other end is detachably connected to one end of the filter 3. One end of the second delivery pipe 52 is detachably connected to the input end of the magnetic pump 4, and the other end is detachably connected to the other end of the filter 3. One end of the third delivery pipe 53 is detachably connected to the output end of the magnetic pump 4, making installation easy. The filter 3 retains lumps or other solid impurities in the glue inside the filter 3, while the glue that meets the requirements flows out of the outlet of the filter 3 and enters the magnetic pump 4 through the second delivery pipe 52. A discharge port 13 is provided at the bottom of the glue storage tank 1, and one end of the first delivery pipe 51 is connected to the discharge port 13.

[0031] The glue supply transmission device of the cigarette assembling machine in this embodiment may further include a plurality of ball valves 2 respectively provided on the first delivery pipe 51 , the second delivery pipe 52 , and the third delivery pipe 53 .

[0032] Specifically, ball valves 2 are provided on the first delivery pipe 51, the second delivery pipe 52, and the third delivery pipe 53, thereby adding ball valves 2 between the glue storage tank 1, the filter 3, and the magnetic suction pump 4. This facilitates cleaning the filter screen 31 inside the filter 3 or replacing the filter element, as well as cleaning and maintenance of the glue storage tank 1, the magnetic suction pump 4, and other components, effectively preventing glue leakage in the pipes. The ball valves 2 can be manual ball valves.

[0033] The upper portion of the glue storage tank 1 may be provided with a feed port 12 , and further includes a sealing cover 14 detachably connected to the glue storage tank 1 for sealing the feed port 12 .

[0034] Specifically, when the glue in the glue storage tank 1 is insufficient, the sealing cover 14 is opened, the fourth delivery pipe is passed through the feed port 12 and extended into the inside of the glue storage tank 1, and glue is added to the glue storage tank 1 through the fourth delivery pipe.

[0035] The weighing element may include a gravity sensor 11 for weighing the glue storage tank 1 to obtain the real-time weight of the glue storage tank 1 .

[0036] Specifically, it also includes a support platform 15 for supporting the glue storage tank 1, and the gravity sensor 11 is arranged on the top surface of the support platform 15. When the glue storage tank 1 is placed on the support platform 15, the gravity sensor 11 can weigh the glue storage tank 1. The gravity sensor 11 is a device that can convert the acceleration caused by gravity into a voltage output. By measuring the acceleration caused by gravity, the inclination angle of the device relative to the horizontal plane can be calculated, which is indirectly used to measure weight. The working principle of the gravity sensor 11 is based on the piezoelectric effect, that is, when an external force is applied to an isopolar crystal without a center of symmetry, in addition to causing the crystal to deform, it also changes the polarization state of the crystal and establishes an electric field inside the crystal. This phenomenon of polarization of the medium by mechanical force is called the positive piezoelectric effect. The gravity sensor 11 utilizes the internal crystal deformation characteristics caused by acceleration, measures its deformation amount and converts it into a voltage output using relevant circuits, thereby achieving weight measurement.

[0037] The weighing element may further include an alarm 62 and a second controller 61 for controlling the alarm 62 to sound an alarm when the real-time weight is less than a preset weight.

[0038] Specifically, the glue in glue tank 1 is qualified glue. A gravity sensor 11 is installed below glue tank 1. When the glue gravity is too low, second controller 61 controls alarm 62 to sound an alarm, reminding employees to add glue in time. Alarm 62 can be an audible and visual alarm 62, and second controller 61 can be a single-chip microcomputer. Gravity sensor 11 and second controller 61 are connected by wire or wirelessly, and second controller 61 and alarm 62 are connected by wire or wirelessly.

[0039] The filter 3 may include a filter body, and a filter screen 31 disposed in the filter body for filtering the glue. The filter screen 31 is detachably connected to the filter body.

[0040] Specifically, a filter 3 is connected to the back of the glue tank to filter out impurities such as solid particles that may not have been processed or newly produced lumps in the glue. During the glue adding process, the glue impurities will generate pulses on the pump body, which is reflected in the gear pump or magnetic suction pump 4 as a sudden radial force on the gear shaft, which is also one of the main reasons for the wear of the gear pump of the original system. Long-term use of this glue containing impurities will aggravate the wear of the pump. In addition, glue impurities can also cause quality accidents, such as glue breakage. However, this kind of impurity is unpredictable, and this impurity will exist if there is no glue pretreatment or the pretreatment is unqualified. Therefore, it is necessary to add a filter 3 before the magnetic suction pump 4. By selecting a suitable filter 3, the lumps in the glue can be filtered out. It should be noted that during the use of the filter 3, the filter screen 31 needs to be cleaned or replaced periodically to prevent glue impurities from clogging the filter 3 and making it impossible to discharge glue.

[0041] A first thread groove may be provided on the inner wall of the glue storage tank 1 at the feed port 12 , and a first thread portion 141 matching the first thread groove is provided on the sealing cover 14 .

[0042] Specifically, when the first threaded portion 141 is screwed into the first thread groove, the sealing cover 14 is fixedly connected to the glue storage tank 1, thereby improving the stability of the connection between the sealing cover 14 and the glue storage tank 1, and thereby improving the sealing of the feed port 12. The sealing cover 14 is rotated along a first preset direction so that the first threaded portion 141 and the first thread groove are separated, thereby separating the sealing cover 14 and the glue storage tank 1. The first threaded portion 141 and the first thread groove are aligned and the sealing cover 14 is rotated along a second preset direction so that the first threaded portion 141 and the first thread groove are firmly connected, thereby firmly connecting the sealing cover 14 and the glue storage tank 1.

[0043] The contents described above can be implemented individually or in combination in various ways, and these variations are all within the scope of protection of the present invention.
