Description

Technical Field

[0001] The utility model relates to the technical field of cigarette making machinery and equipment, and more specifically, to a cigarette making machine sealer heating device. Background Art

[0002] During the tobacco rod production process, tobacco shreds enter the cigarette paper and are wrapped by it. A glue sprayer then applies glue to the joints of the tobacco-wrapped cigarette paper. After the glue is applied, the joints of the tobacco rod are closed by a pressure plate, and the glue adheres to both sides of the cigarette paper, wrapping the tobacco shreds and forming a continuous tobacco rod. After the tobacco rod is formed and before it enters the subsequent process, the glue on the joints must dry to ensure a secure bond. Otherwise, the joints may break, causing the rod to burst, resulting in defective products or even downtime. Therefore, after the tobacco rod is glued and formed, a sealer is used to heat and seal the joints, rapidly drying the glue and forming a solid tobacco rod. The most important component of the sealer is the heater located at its lower portion. When the heater is powered on and heated, it contacts the joints of the tobacco rod, drying the glue.

[0003] At present, only a small area (center) of the existing heating body contacts the tobacco rod. The small heating area results in poor heating effect. In addition, the temperature of the heating body is difficult to control, which can easily cause problems such as tobacco rod bursting and glue overflow, resulting in reduced production efficiency.

[0004] Therefore, how to provide a cigarette sealing device heating device has become a technical problem that needs to be solved urgently in this field. Utility Model Content

[0021] 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 arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0024] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0025] like Figures 1 to 2 As shown, an embodiment of the present invention provides a cigarette machine sealer heating device, comprising: a first heating body 1, a second heating body 2, a thermistor 3 and a heating core rod 4, and the bottom of the first heating body 1 is connected to the top of the second heating body 2.

[0026] The thermistor 3 and the heating core rod 4 are both arranged on the first heating body 1. The thermistor 3 is used to detect problems with the first heating body 1, and the heating core rod 4 is used to heat the first heating body 1 and the second heating body 2; the bottom of the second heating body 2 is provided with a tobacco rod heat sealing groove 21 for heat sealing the tobacco rod, and the tobacco rod heat sealing groove 21 covers at least one third of the circumference of the tobacco rod.

[0027] Furthermore, the cigarette making machine sealer heating device of the present invention also includes an alarm and a two-color LED lamp, and the thermistor 3 is electrically connected to the alarm and the two-color LED lamp.

[0028] During use, the temperature of the first heating element 1 is monitored in real time by the thermistor 3. When the temperature of the first heating element 1 is too low, the thermistor 3 sends a signal to the alarm, which then sounds an alarm and controls the two-color LED light to display yellow, thereby reminding the operator that the temperature of the first heating element 1 is too low, allowing the operator to clearly and intuitively know that the temperature of the first heating element 1 is too low.

[0029] When the temperature of the first heating body 1 is too high, the thermistor 3 sends a signal to the alarm, which then sounds an alarm and controls the two-color LED light to display a red light, thereby reminding the operator that the temperature of the first heating body 1 is too high, so that the operator can clearly and intuitively get the problem of the temperature of the first heating body 1 being too high, and then the operator can quickly adjust the output power of the heating core rod 4 to make the temperature of the first heating body 1 reach the preset temperature, so that the heating temperature of the tobacco rod by the first heating body 1 can be regulated.

[0030] The present invention connects the bottom of the first heating body 1 with the top of the second heating body 2, and arranges the thermistor 3 for detecting the temperature of the first heating body 1 and the heating core rod 4 for heating the first heating body 1 and the second heating body 2 on the first heating body 1. The bottom of the second heating body 2 is provided with a tobacco rod heat sealing groove 21 for heat-sealing tobacco rods. During use, the temperature of the first heating body 1 is monitored in real time by the thermistor 3. When the temperature of the first heating body 1 is too low or too high, the output power of the heating core rod 4 is adjusted to make the temperature of the first heating body 1 reach the preset temperature, thereby being able to regulate the heating temperature of the tobacco rod by the first heating body 1; and the tobacco rod heat sealing groove 21 covers at least one-third of the circumference of the tobacco rod, thereby effectively increasing the contact area between the tobacco rod heat sealing groove 21 and the tobacco rod, solving the problems of tobacco rod bursting and glue overflow caused by the prior art, and improving the heating effect and production efficiency of the tobacco rods.

[0031] In one embodiment of the cigarette sealing device heating device of the present invention, as Figure 1 As shown, the tobacco rod heat sealing groove 21 is an arc-shaped structure, the diameter of the tobacco rod heat sealing groove 21 is equal to the diameter of the tobacco rod, and the arc length of the tobacco rod heat sealing groove 21 is at least one third of the circumference of the tobacco rod.

[0032] Specifically, the size and shape of the tobacco rod heat sealing groove 21 are completely consistent with the size and shape of the tobacco rod.

[0033] By designing the tobacco rod heat-sealing groove 21 as an arc-shaped structure and ensuring that the arc length of the tobacco rod heat-sealing groove 21 is at least one-third of the tobacco rod's circumference, the utility model ensures that the tobacco rod heat-sealing groove 21 is in full contact with the tobacco rod, thereby increasing the contact area and improving the heating effect. This effectively reduces the probability of tobacco rod breakage, cracking, and glue overflow. Furthermore, it prevents the second heating element 2 from flattening the tobacco rod, improves the roundness of the cigarette cross-section, and enhances the appearance quality of the cigarette.

[0034] In one embodiment of the cigarette making machine sealer heating device of the present invention, the cigarette making machine sealer heating device further includes a connecting block 5, the two ends of the connecting block 5 are respectively connected to the first heating body 1 and the second heating body 2, and the vertical cross-section of the connecting block 5 is trapezoidal.

[0035] Specifically, the short side of the connecting block 5 is connected to the second heating body 2 , and the long side of the connecting block 5 is connected to the first heating body 1 .

[0036] The utility model connects the two ends of the connecting block 5 to the first heating body 1 and the second heating body 2 respectively, and sets the vertical cross-section of the connecting block 5 to a trapezoid, thereby ensuring the stability of the connection between the first heating body 1 and the second heating body 2, and also reducing heat loss, so that more heat is transferred to the second heating body 2, further improving the heating efficiency.

[0037] Furthermore, the first heating body 1, the second heating body 2 and the connecting block 5 are integrally formed.

[0038] In one embodiment of the cigarette making machine sealer heating device of the present invention, in order to further improve the thermal conductivity, the first heating body 1, the second heating body 2 and the connecting block 5 are all made of high thermal conductivity ceramic materials, which have high thermal conductivity efficiency and reduce power consumption.

[0039] In one embodiment of the cigarette sealing device heating device of the present invention, as Figures 1 to 2 As shown, the first heating body 1 is provided with a first mounting hole 11 and two second mounting holes 12 arranged in sequence, the thermistor 3 is inserted into the first mounting hole 11, the heating core rod 4 is inserted into the second mounting hole 12, and the hole length of the second mounting hole 12 is greater than the hole length of the first mounting hole 11.

[0040] Specifically, two heating core rods 4 can be inserted into the two second mounting holes 12 , or a heating core rod 4 can be inserted into one of the second mounting holes 12 .

[0041] To improve heating efficiency, two heating core rods 4 can be inserted into each of the two second mounting holes 12. To save energy, a heating core rod 4 can be inserted into one of the second mounting holes 12. To improve the accuracy of temperature measurement of the first heating body 1, a heating core rod 4 can be inserted into one of the second mounting holes 12, and two thermistors 3 can be inserted into the other second mounting hole 12 and the first mounting hole 11.

[0042] The heating core rod 4 and the thermistor 3 can be freely combined according to heating needs, thereby improving the adjustability of the heating effect.

[0043] In one embodiment of the cigarette sealing device heating device of the present invention, as Figure 2 As shown, the cigarette making machine sealer heating device also includes an adjusting component 6, which includes a fixed rod 61, a slider 62 and a connecting rod 63. The fixed rod 61 is connected to the cigarette making machine, the slider 62 is slidably connected to the fixed rod 61, and the slider 62 is connected to the first end of the connecting rod 63, and the second end of the connecting rod 63 is connected to the first heating body 1.

[0044] It should be noted that after maintenance personnel repair the first heating body 1 and the second heating body 2, the positions of the first heating body 1 and the second heating body 2 will change, and the distance between the tobacco rod heat sealing groove 21 and the tobacco rod will change.

[0045] When the distance between the tobacco rod heat sealing groove 21 and the tobacco rod is too large, the contact area between the tobacco rod heat sealing groove 21 and the tobacco rod is reduced. The smaller heating area leads to poor heating effect at this time, and the tobacco rod may burst or overflow with glue.

[0046] If the distance between the heat-sealing groove 21 and the tobacco rod is too small, the groove 21 exerts a large pressure on the top of the tobacco rod, and the inner wall of the groove 21 can deform the tobacco rod, resulting in a poorly rounded cross-section of the produced cigarette and even damaging the joint of the tobacco rod. Therefore, the position of the connecting rod 63 is adjusted by the slider 62, which drives the connecting rod 63 up and down, thereby adjusting the distance between the heat-sealing groove 21 and the tobacco rod.

[0047] The utility model connects the fixed rod 61 to the cigarette making machine, the slider 62 is slidably connected to the fixed rod 61, and the slider 62 is connected to the first end of the connecting rod 63, and the second end of the connecting rod 63 is connected to the first heating body 1. The slider 62 moves on the fixed rod 61, thereby driving the connecting rod 63 to move up and down, thereby driving the first heating body 1 to move up and down, so as to adjust the distance between the tobacco rod heat sealing groove 21 and the tobacco rod, thereby avoiding the problem of poor heat sealing effect caused by excessively large or too small distance between the tobacco rod heat sealing groove 21 and the tobacco rod.

[0048] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may 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.
