Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive machines, in particular to a hot melt adhesive machine with a quick cleaning mechanism. Background Art

[0002] In the existing food packaging industry's processing lines, hot melt adhesive sealing procedures are generally used to replace traditional strapping and tape packaging. In this process, a special hot melt adhesive machine is usually installed on the line to heat and produce high-temperature liquid hot melt adhesive that can be used for sealing operations, so that the electrical automation equipment of the production line can perform automatic gluing operations by controlling the glue gun.

[0003] However, the existing hot melt adhesive machines have certain usage defects in actual use, which are usually manifested in that the existing equipment does not have a certain tank wall quick cleaning structure design in the hot melt adhesive heating tank body, so that when the hot melt adhesive heating tank body is not processed, the solidified hot melt adhesive adhered to its inner wall can only be cleaned by melting it again with a hot machine and then by other cleaning means. Its cleaning efficiency is not ideal. Therefore, those skilled in the art provide a hot melt adhesive machine with a quick cleaning mechanism to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a hot melt adhesive machine with a quick cleaning mechanism to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a hot melt adhesive machine with a quick cleaning mechanism, comprising a heating tank structure, a first cleaning structure and a second cleaning structure, wherein the first cleaning structure and the second cleaning structure are arranged inside the heating tank structure, and the heating tank structure comprises a tank body, the first cleaning structure comprises a planetary gear ring rotatably arranged in the tank body, and a plurality of cleaning scraping rods equidistantly fixedly connected to the bottom of the planetary gear ring and a limiting ring fixedly connected to the bottom of the plurality of cleaning scraping rods, the second cleaning structure comprises a cleaning scraping block slidably arranged on the upper side of the plurality of cleaning scraping rods and a connecting frame fixedly connected to the plurality of cleaning scraping blocks respectively.

[0006] Furthermore, multiple stirring rods are equidistantly fixedly connected to the sides of the shafts of the multiple cleaning scraping rods. A limit ring is fixedly provided at the bottom end of the multiple cleaning scraping rods. The limit ring is provided at the bottom end of the tank body and cooperates with the bottom end of the tank body to limit rotation. The multiple stirring rods provided on the cleaning scraping rods enable the first cleaning structure of the device to simultaneously perform a stirring function while in operation. The provision of the limit ring and its cooperation with the bottom end of the tank body ensure the stability of the first cleaning structure during its own rotation.

[0007] Furthermore, a pair of limiting grooves are formed on one side of the shaft of each of the plurality of cleaning scraping rods, and a pair of limiting blocks are fixedly connected to the sides of the plurality of cleaning scraping blocks at positions corresponding to the plurality of limiting grooves. The plurality of limiting blocks and the pair of limiting grooves are mutually limited and slidably engaged. The provided limiting grooves and limiting blocks, as well as the cooperative relationship between the two, ensure the movement stability of the cleaning scraping blocks during the cleaning process.

[0008] Furthermore, multiple planetary gears are equidistantly mounted within the inner groove of the upper end of the planetary gear ring. Each of these planetary gears meshes with the inner gear ring at the upper end of the planetary gear ring. The planetary gears and the planetary gear ring, and the meshing relationship between them, form a transmission structure that enables the drive motor above the tank lid to drive the first cleaning structure to rotate, stir, and clean the inner wall of the tank. This transmission mechanism also functions as a speed reducer, enabling the first cleaning structure to achieve low-speed, high-torque performance, reducing the lifespan of the drive motor.

[0009] Furthermore, the heating tank structure also includes a tank cover sealed and fixedly connected to the upper end of the tank body, and a driving structure is provided at the upper end of the tank cover. The driving structure includes an electric telescopic cylinder fixedly arranged at the middle position of the upper end of the tank cover and a plurality of driving motors equidistantly fixed at the upper end of the tank cover. The output end of the electric telescopic cylinder passes through the tank cover and is rotatably connected to the middle position of the upper end of the connecting frame. The output ends of the plurality of driving motors all pass through the tank cover and are fixedly connected to the upper ends of a plurality of planetary gears.

[0010] Furthermore, a feeding port is fixedly connected to the upper end of the tank cover at the position of the output end, so that the feeding port is convenient for the operator to add hot melt adhesive pellets or hot melt adhesive blocks into the tank body.

[0011] Furthermore, the output end of the tank is provided with a hot melt adhesive delivery structure, which includes a heat-insulating adhesive delivery pipeline connected to the output end of the tank and a glue gun connected to the output end of the heat-insulating adhesive delivery pipeline. The heat-insulating adhesive delivery pipeline and glue gun facilitate the delivery of heated liquid hot melt adhesive from the tank along the heat-insulating adhesive delivery pipeline to the glue gun, which then applies the adhesive.

[0012] Compared with the prior art, the present invention provides a hot melt adhesive machine with a quick cleaning mechanism, which has the following beneficial effects:

[0013] The device of this design, through the first cleaning structure arranged inside the tank body, can simultaneously scrape and clean the inner wall of the tank body as the device stops and stops heating, and can also stir the hot melt adhesive in the tank body to slow down the solidification speed of the hot melt adhesive in the tank body. After completing the scraping and cleaning of the inner wall of the tank body, the second cleaning structure in the device can clean the liquid hot melt adhesive adhered to the cleaning scraper rod under the drive of the driving structure. The overall structural design enables the device to quickly and effectively clean the colloid on the inner wall of the device heating tank, and the colloid adhered to the first cleaning structure can be cleaned through the second cleaning structure.

[0025] Furthermore, a plurality of planetary gears 42 are equidistantly arranged on the inner side of the upper groove of the planetary gear ring 41, and the plurality of planetary gears 42 are meshed and transmitted with each other with the gear ring on the inner side of the upper end of the planetary gear ring 41; the planetary gears 42 and the planetary gear ring 41 and the meshing relationship between the two constitute a set of transmission structure, so that the drive motor 32 above the tank cover 22 can drive the first cleaning structure 4 to rotate and stir and clean the inner wall of the tank body 21 by driving the structure; at the same time, the transmission mechanism also has the function of a reducer, so that the first cleaning structure 4 has the function of low speed and high torque, which reduces a certain life loss of the drive motor 32. Example 2:

[0026] Based on the above embodiment 1, please refer to Figures 1 to 6A hot melt adhesive machine with a quick cleaning mechanism, the heating tank structure 2 also includes a tank cover 22 that is sealed and fixedly connected to the upper end of the tank body 21, and a driving structure 3 is provided on the upper end of the tank cover 22.

[0029] The working principle and use process of this utility model: When the device is actually used:

[0030] When the device is working, as the hot melt adhesive heating tank gradually stops, the operator can control the drive motor 32 through the control terminal to operate. The working drive motor 32 drives the planetary gear 42 in the tank body 21 to rotate, thereby synchronously driving the planetary gear ring 41, the cleaning scraper 44 and the stirring rod 43;

[0031] The rotating cleaning scraper 44 quickly scrapes and cleans the liquid hot melt adhesive adhering to the inner wall of the tank body 21, and the rotating stirring rod 43 can also delay the solidification of the hot melt adhesive in the tank body 21;

[0032] After the inner wall of the tank body 21 is cleaned, the operator stops the driving motor 32 through the control terminal and controls the electric telescopic cylinder 31 to operate. The operating electric telescopic cylinder 31 extends the connecting frame 51 and simultaneously drives the multiple cleaning scrapers 52 at the end of the connecting frame 51 to slide downward, scraping the hot melt adhesive adhered to the cleaning scraper rod 44 to the bottom end of the tank body 21, completing the rapid cleaning operation inside the tank body 21.

[0033] The overall design allows the device to quickly clean the hot melt adhesive adhering to the inner wall of the tank body 21 to the bottom of the device after shutdown, avoiding the hardening of the adhesive adhering to the inner wall of the tank body and making it difficult to clean.
