Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of mechanical equipment for cigarettes, in particular to an electric heating glue removal scraper. Background Art

[0002] In the current filter rod manufacturing process, four types of colloids are generally used: hot melt glue, hollow glue, spray glue and double-sided glue. Among them, hot melt glue and hollow glue are used to bond the overlap of filter rod forming paper, spray glue is used to fix the wire bundle to prevent the wire bundle and forming paper from slipping off during slitting, and double-sided glue is used to splice the forming paper and the wire bundle to ensure that the equipment can continue to produce. These types of glue are indispensable raw materials in the filter rod manufacturing process. However, they will inevitably adhere to the equipment due to glue leakage and other reasons during production and use, forming glue blocks that are difficult to remove. This causes many inconveniences to the daily maintenance of the equipment. At present, the viscosity of most common glues on the market will decrease with the increase of temperature. This is mainly because heating can destroy the binding force between glue molecules, thereby causing a decrease in viscosity. Therefore, heating can be used to improve the efficiency of glue removal during maintenance. At present, there are already electric hot glue removal shovels with heating function on the market, but they are heated by directly heating the metal blade to achieve heating and glue removal, and the heated metal blade can easily cause damage to the surface of the equipment, which greatly limits its scope of application.

DETAILED DESCRIPTION

[0030] The core of the utility model is to provide an electric thermal degumming scraper. The structural design of the electric thermal degumming scraper can reduce or avoid damage to the surface of the equipment caused by the scraper during the degumming process, thereby expanding the application range of the electric thermal degumming scraper.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 and Figure 2 , Figure 1 This is a front view of the electric heating glue removal scraper provided in an embodiment of the utility model. Figure 2 A top view of the electric heating glue removal scraper provided in an embodiment of the utility model.

[0033] The utility model discloses an electric heating glue removal scraper, which comprises a scraper body 1 and an electric heating device.

[0034] Among them, the scraper body 1 includes a handle 110 and a cutter head 120 arranged at one end of the handle 110. The handle 110 can be made of metal, wood, plastic, rubber and other materials. The switch and power supply component of the electric heating device can be arranged on the handle 110. The cutter head 120 and the handle 110 can be fixedly connected or detachably connected. Of course, the cutter head 120 is preferably installed on the handle 110 in a detachable manner to facilitate maintenance and replacement. The detachable cutter head 120 makes the electric heating degumming scraper more flexible, and the appropriate cutter head 120 can be replaced according to the position and state of the glue block. The electric heating device includes a mounting bracket 2 and a heating roller 3. One end of the mounting bracket 2 is connected to the handle 110, and the other end is rotatably connected to the heating roller 3. The mounting bracket 2 places the heating roller 3 in front of the degumming path of the cutter head 120, that is, the heating part of the electric heating degumming scraper is separated from the cutter head 120.

[0035] It can be seen that compared with the prior art, when the electric thermal glue removal scraper provided in the embodiment of the utility model is used, first the heating roller 3 is energized to start heating it, and then the heating roller 3 and the cutter head 120 are pressed simultaneously on the glue position 5, and the electric thermal glue removal scraper is pushed forward. Since the heating roller 3 is in front of the glue removal path of the cutter head 120, the heating roller 3 will heat the glue block to be scraped off before the cutter head 120, thereby producing an ironing effect and quickly softening the glue block. When the cutter head 120 reaches this position, the softened glue block can be smoothly scraped off, making the glue removal work more time-saving and labor-saving. Since the cutter head 120 itself is not heated and the heating roller 3 itself has no sharp parts, it can effectively reduce or avoid damage to the surface of the equipment by the cutter head 120 during the glue scraping process, which helps to expand the application range of the electric thermal glue removal scraper.

[0036] In a preferred embodiment of the utility model, the blade head 120 is detachably connected to the handle 110. By designing the blade head 120 as a detachable structure, when the blade head 120 is worn, only the blade head 120 can be replaced without replacing other parts. In addition, the blade head 120 of a suitable shape can be replaced according to the shape, width and space size of the rubber block to be removed, thereby improving work efficiency and glue removal effect, and expanding the application range of the electric thermal glue removal scraper.

[0037] Specifically, Figures 1 to 5 As shown, in a preferred embodiment, the handle 110 includes a main body 111 and a blade head 120 fixing portion 112 arranged at one end of the main body 111. The main body 111 is used for the user to hold. The cross-section of the main body 111 can be a circular, elliptical or other shape that is convenient for holding. Of course, finger grooves can also be provided on the main body 111 to cooperate with the user's fingers, thereby increasing the stability of holding. The blade head 120 fixing portion 112 is provided with a blade head 120 mounting groove 112a and a fastening structure for fastening the blade head 120 in the blade head 120 mounting groove 112a.

[0038] Specifically, Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, the fastening structure includes a threaded fastener 113 and a fastening assembly hole 112b provided on the fixing portion 112 of the cutter head 120. The cutter head 120 is provided with an assembly through hole 120a. The fastening assembly hole 112b penetrates the installation groove 112a of the cutter head 120. The threaded fastener 113 is threadedly matched with the fastening assembly hole 112b and passes through the assembly through hole 120a of the cutter head 120 to fix the cutter head 120 to the installation groove 112a of the cutter head 120. It can be foreseen that the cutter head 120 is fixed by only one threaded fastener 113. During the glue removal process, the cutter head 120 is easily rotated due to the force, so the cutter head 120 installation groove 112a is provided with a limiting structure for cooperating with other parts of the cutter head 120 except the blade. In a preferred embodiment, the groove bottom surface of the cutter head 120 installation groove 112a is in contact with the end of the cutter head 120 away from the blade, that is, the back of the cutter head 120, so as to achieve the positioning of the cutter head 120. Of course, the positioning of the cutter head 120 can also be achieved by other means, such as the cutter head 120 can also be positioned by multiple threaded fasteners 113.

[0039] Specifically, to facilitate operation and ensure that the heating roller 3 can always maintain a close fit with the glue position 5 during the glue removal process to ensure the heating effect on the glue position 5, in an embodiment of the utility model, one end of the mounting bracket 2 is rotatably connected to the handle 110, and an elastic preload 4 is arranged between the mounting bracket 2 and the handle 110. The elastic preload 4 is used to apply a pressure greater than or equal to a preset pressure to the glue position 5 when the electric heating glue removal spatula removes the glue block at the glue position 5. When used, the heating roller 3 can be pressed on the glue position 5 first, and then pressure is applied to the handle 110 to make the heating roller 3 and the cutter head 120 rotate relative to each other. The elastic preload 4 is stretched or compressed to generate a force that presses the heating roller 3 on the glue position 5. When the cutter head 120 is also in close contact with the glue position 5, glue removal can begin.

[0040] Specifically, Figure 1 As shown, in an embodiment of the utility model, the above-mentioned mounting bracket 2 includes two curved arms 210, which are arched in a direction away from the handle 110, and the first ends of the two curved arms 210 are rotatably connected to the handle 110 respectively, and the heating roller 3 is rotatably arranged between the second ends of the two curved arms 210.

[0041] like Figure 2 As shown, the elastic preload member 4 includes two symmetrically arranged preload springs, one end of which is connected to the curved arm 210, and the other end of which is connected to the handle 110, that is, a mounting hole 112c is provided on the fixing portion 112 of the blade head 120 of the handle 110, and the other end of the preload spring is fixed in the mounting hole 112c. When no external force is applied, under the action of the preload spring, the axis of the heating roller 3 and the preload spring are respectively located on both sides of the surface where the blade of the blade head 120 is located, as shown in FIG. Figure 1 shown.

[0042] During the degumming process, Figure 8 As shown, after the heating roller 3 is pressed against the glue position 5, the handle 110 is rotated relative to the heating roller 3 so that the cutter head 120 is also pressed against the glue position 5. During this process, the two preloaded springs are stretched, generating elastic force to press the heating roller 3 against the glue position 5.

[0043] like Figure 7 As shown, the heating roller 3 includes a metal sleeve 320 and an electric heating rod 310. The electric heating rod 310 is arranged in the metal sleeve 320. Preferably, the inner surface of the metal sleeve 320 is a smooth metal surface. The metal sleeve 320 should be made of high temperature resistant and corrosion resistant materials, such as aluminum alloy or stainless steel. The electric heating rod 310 is a constant temperature electric heating rod 310. The electric heating rod 310 and the metal sleeve 320 cooperate in heat conduction. After the heating roller 3 is powered on, the internal constant temperature electric heating rod 310 starts to heat up and transfers the heat to the external metal sleeve 320, so that the temperature of the outer surface of the metal sleeve 320 is controlled between 30°C and 70°C.

[0044] To further optimize the above technical solution, in an embodiment of the utility model, in order to prevent the metal sleeve 320 of the heating roller 3 from causing damage to the surface of the equipment, the heating roller 3 also includes a rubber sleeve, which is arranged on the circumferential outer surface of the metal sleeve 320. This not only achieves further protection for the surface of the equipment, but also the rubber sleeve can make the heating roller 3 better fit the surface of the equipment.

[0045] Preferably, the electrical connection structure of the heating roller 3 is arranged in the inner cavity of the handle 110. The electrical connection structure can be an electric wire with a plug. The end of the wire away from the plug is electrically connected to the electric heating rod 310 in the heating roller 3. In a non-working state, the wire and the plug can be stored in the inner cavity of the handle 110. When glue removal is required, the wire and the plug can be taken out of the handle 110 to connect to the power supply device. Of course, a battery can also be set in the inner cavity of the handle 110, and the battery is used to power the heating roller 3. There is no need to set wires, which makes the electric heating glue removal scraper more flexible and not restricted by wires.

[0046] To further optimize the above technical solution, a lighting fixture is also provided at one end of the handle 110 where the blade 120 is installed. The lighting fixture provides lighting for the user when the ambient light at the glue position 5 is weak, thereby improving the glue removal efficiency and effect.

[0047] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
