Abstract
Description
Technical Field
[0001] This utility model relates to the field of PUR glue melting technology, and in particular to a PUR glue melting device. Background Technology
[0002] Chinese patent document CN221679579U discloses a pressurized material tank for the production of PUR hot melt adhesive, including a storage tank, a tank cover, a feed pipe, and a discharge pipe. The tank cover is movably installed on the top of the storage tank. The feed pipe is connected to the top of the side wall of the storage tank, and the discharge pipe is connected to the bottom of the side wall of the storage tank. A drive motor is installed on the top surface of the tank cover, and the power output end of the drive motor is connected to a stirring paddle via a coupling. A lifting plate is movably provided in the inner cavity of the storage tank. Hydraulic rods are symmetrically installed on the top surface of the tank cover. The piston rod of the hydraulic rod penetrates the inner wall of the tank cover, and the end of the piston rod is connected to the lifting plate. This invention increases the air pressure at the top of the inner cavity of the storage tank, allowing the PUR hot melt adhesive raw material at the bottom of the inner cavity to be quickly discharged from the discharge pipe under the action of air pressure, thus achieving rapid discharge of the PUR hot melt adhesive raw material.
[0003] The pressurized material tank for PUR hot melt adhesive production mentioned above has the following characteristics: when the adhesive blocks are melted in the storage tank, due to the short length of the stirring paddle, large adhesive blocks may easily get stuck together during the melting process, forming "bridge-shaped" voids and blocking the discharge pipe. This may result in the inability to discharge smoothly and reduce the efficiency of the melting process. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a PUR glue melting device, including a storage tank 1 and an anti-blocking mechanism 3. A top cover 2 is snapped onto the top of the storage tank 1, and a grid 4 and two sets of threaded pins 8 are provided inside the storage tank 1. The anti-blocking mechanism 3 is provided on the top cover 2 and is used to drive the grid 4 to prevent glue blocks from bridging and blocking.
[0024] The anti-blocking mechanism 3 includes a motor 301, gears 302, a rotating rod 303, and a fixing block 304. The motor 301 is fixedly installed on the top of the top cover 2, and the rotating rod 303 is rotatably installed on the top of the top cover 2. There are two sets of gears 302. The output shaft of the motor 301 and one end of the rotating rod 303 are both fixedly connected to one set of gears 302. The two sets of gears 302 mesh with each other. The other end of the rotating rod 303 extends into the interior of the storage tank 1 and is fixedly installed with a fixing block 304. The anti-blocking mechanism 3 can drive the grid 4 to rotate, thereby preventing the accumulation of rubber blocks on the grid 4.
[0025] The inner side of the grille 4 contacts the outer wall of the fixing block 304.
[0026] A hydraulic rod 5 is fixedly installed on the top of the top cover 2. The free end of the hydraulic rod 5 extends into the interior of the storage tank 1 and is fixedly installed with a sliding plate 6. Multiple sets of conical heads 7 are fixedly installed at the bottom of the sliding plate 6. The sliding plate 6 and the rotating rod 303 are slidably installed. The hydraulic rod 5 can drive the conical heads 7 to move downward to contact the glue block and crush the larger glue blocks. This prevents the glue blocks from easily getting stuck together during the melting process and forming "bridge"-shaped voids, thus avoiding the situation where the material cannot be discharged smoothly and improving the working efficiency of melting glue.
[0027] The top of the fixing block 304 and the top of the grid 4 are provided with two sets of insertion holes. The two ends of the two sets of threaded pins 8 extend to the bottom of the grid 4 through a set of insertion holes located on the top of the storage tank 1 and the top of the grid 4. The outer walls of the two sets of threaded pins 8 are threaded with a set of nuts 9. The threaded pins 8 are slidably installed with the fixing block 304 and the grid 4 respectively. When the grid 4 needs to be cleaned, the grid 4 and the fixing block 304 can be separated and the grid 4 can be removed for easy cleaning, avoiding the situation where molten adhesive solidifies and accumulates on the surface of the grid 4, clogging the grid 4.
[0028] Two sets of heating plates 12 are fixedly installed on the outer wall of the storage tank 1. Three sets of support legs 11 are fixedly installed on the outer wall of the storage tank 1. A discharge pipe 10 is fixedly installed on the outer wall of the storage tank 1. One end of the discharge pipe 10 extends into the interior of the storage tank 1. A knob cover is threaded to the other end of the discharge pipe 10. A door is hinged to the outer wall of the storage tank 1. A handle is fixedly installed on the front side of the door.
[0029] Working principle: When work is required, the top cover 2, along with its related components, is installed and snapped into the storage tank 1. The door is opened, and the rubber blocks are put into the storage tank 1. Larger rubber blocks fall onto the surface of the grid 4. The heating plate 12 is activated to heat the inside of the storage tank 1. The motor 301 is activated, and its output shaft drives a set of gears 302 to rotate. Through the two sets of meshing gears 302, the rotating rod 303 is driven to rotate. The rotating rod 303 drives the fixed block 304 to rotate, which in turn drives the grid 4 to rotate, preventing the rubber blocks from accumulating on the surface of the grid 4. The hydraulic rod 5 is activated, and its free end drives the sliding plate 6 to move downward, which causes multiple sets of conical heads 7 to press down and break larger rubber blocks. The rubber liquid can be discharged and collected by opening the discharge pipe 10. When it is necessary to clean the surface of the grid 4, the top cover 2 is separated from the storage tank 1 and removed. The four sets of nuts 9 are rotated to remove the two sets of threaded pins 8, which can separate the grid 4 from the fixed block 304, thus facilitating the cleaning and maintenance of the grid 4.
[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
