Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hot melt adhesive granulation, and in particular to a hot melt adhesive granulation and discharge mechanism. Background Technology
[0002] A granulator is a molding machine that can shape waste materials into specific shapes. The processing range of granulators includes waste plastic film, woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, daily necessities, etc. It is suitable for most common waste materials that can be recycled. It is the most widely used, most popular, and most widely used recycling processing machine in the recycling industry. Granulators can also be used for the recycling of hot melt adhesives. After the hot melt adhesives are recycled and granulated, the temperature is usually high, close to or slightly lower than the extrusion melting temperature of the hot melt adhesives, typically between 80°C and 120°C. At this temperature, the granules are still soft and sticky, and are easily deformed or stick together. In order to facilitate storage, transportation and subsequent use, the freshly cut high-temperature granules must be cooled. The target cooling temperature is to allow the granules to completely solidify, harden, lose their stickiness, and be below their softening point or melting point. The existing cooling method for hot melt adhesive granules is relatively simple. During cooling, the hot melt adhesive granules are not sufficiently dispersed and some clump together, which prevents the internal granules from cooling completely and affects subsequent use.
[0003] To address these issues, we propose a hot melt adhesive granulation and discharge mechanism. Utility Model Content

The frame is located below the granulator, and a discharge pipe is provided on the upper side of the frame. A reciprocating mechanism is provided between the discharge pipe and the inner wall of the frame to drive the pipe to move back and forth. A blade is rotatably connected to the inner wall of the frame located below the discharge pipe. A water-cooling box is installed on the lower side of the frame, and a set of cooling holes is provided on the lower end face of the frame corresponding to the position of the water-cooling box.
[0006] Preferably, a mounting plate is connected to one side wall of the frame, and the mounting plate cooperates with external mounting components.
[0007] Preferably, the upper end of the discharge pipe is connected to a corrugated hose, and the upper end of the corrugated hose is connected to the discharge port of the granulator.
[0008] Preferably, the reciprocating mechanism includes a reciprocating lead screw and a guide rod disposed on the inner wall of the frame, and collars are respectively connected to the side walls at both ends of the discharge pipe. The collars on both sides are respectively sleeved on the outside of the reciprocating lead screw and the guide rod. A drive motor is installed on the side wall of the frame, and the power output end of the drive motor is connected to the reciprocating lead screw.
[0009] Preferably, the blade is designed in an arc shape, a rotating shaft is connected to the side wall of the blade, and a synchronous pulley is connected to the same end of the rotating shaft and the reciprocating lead screw, and a synchronous belt is sleeved on the outside of the synchronous pulley.

[0011] Preferably, a collection box is inserted into the inner side of the insertion frame, and the collection box corresponds to the position of the vibrating screen.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, this invention guides the granulated hot melt adhesive particles into the frame for cooling through the combined action of the discharge pipe and corrugated hose. A reciprocating screw drives the discharge pipe to move back and forth, distributing the hot melt adhesive particles relatively evenly within the frame. Simultaneously, a synchronous belt and pulley ensure that the shaft rotates synchronously with the screw, further dispersing the particles and allowing for more thorough contact with the external cold air, thus improving cooling efficiency. Furthermore, before cooling, a vibrating screen sieves the hot melt adhesive particles, removing any debris that might affect subsequent cooling processes. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1-3A hot melt adhesive granulation and discharge mechanism includes a frame 1 and a granulator. The frame 1 is located below the granulator and corresponds to the discharge port of the granulator. A mounting plate 101 is connected to one side wall of the frame 1. The mounting plate 101 cooperates with external mounting components, which can use fixing bolts and fixing cones. The angle between the mounting plate 101 and the frame 1 is an obtuse angle. When the mounting plate 101 is fixed to the external structure, the frame 1 is inclined relative to the horizontal plane, and its height gradually decreases as it moves away from the discharge port, thereby allowing the hot melt adhesive particles to smoothly move along the frame towards the discharge port. Sliding downwards, a discharge pipe 2 is provided on the upper side of the frame 1. A corrugated hose 201 is connected to the upper end of the discharge pipe 2. The upper end of the corrugated hose 201 is connected to the discharge port of the granulator. The corrugated hose can be bent and moved, so that the discharge pipe 2 is stably connected to the discharge port of the granulator. A reciprocating mechanism 3 is provided between the discharge pipe 2 and the inner wall of the frame 1 to drive it to move back and forth. The reciprocating mechanism 3 includes a reciprocating screw 301 and a guide rod 302 provided on the inner wall of the frame 1. Collars 303 are respectively connected to the side walls at both ends of the discharge pipe 2. The inner wall surface of the collar 303 corresponding to the position of the reciprocating screw 301 is... The reciprocating screw 301 is threaded, with two sets of threads intersecting. When the collar 303 moves to one end of the reciprocating screw 301, it engages with the other set of threads, allowing it to move in the opposite direction. The collars 303 on both sides are respectively fitted onto the outside of the reciprocating screw 301 and the guide rod 302. A drive motor 304, an IHSS57-36-20 servo motor, is mounted on the side wall of the frame 1. The power output end of the drive motor 304 is connected to the reciprocating screw 301. A blade 4 is rotatably connected to the inner wall of the frame 1 below the discharge pipe 2. The overall design is arc-shaped, allowing it to rotate and break up the hot melt adhesive particles, making them disperse better. A rotating shaft 401 is connected to the side wall of the blade 4. The same end of the rotating shaft 401 and the reciprocating screw 301 is connected to a synchronous wheel 402. A synchronous belt 403 is sleeved on the outside of the synchronous wheel 402. The synchronous belt 403 and the synchronous wheel 402 work together to make the rotating shaft 401 rotate synchronously when the reciprocating screw 301 rotates. This causes the discharge pipe 2 to move back and forth to discharge material while the blade 4 breaks it up, thus making the hot melt adhesive particles more dispersed in the frame.
[0020] Based on the above structure, the present invention has the following embodiments: In use, the device is moved to the operating position and installed on the lower side of the granulator using mounting bolts and mounting plate 101. At this time, the frame 1 is tilted. Then, the upper end of the corrugated hose is connected to the discharge port of the granulator. The granulator guides the hot melt adhesive particles from the corrugated hose 201 and the discharge pipe 2 into the frame 1. At the same time, the drive motor 304 is controlled to drive the reciprocating screw 301 to rotate. The collar is threaded with the reciprocating screw 301, and the guide rod 302 and the collar 303 on the other side limit the discharge pipe 2 to prevent it from rotating. This allows the discharge pipe 2 to move laterally back and forth on the upper side of the frame 1, thereby dispersing the hot melt adhesive particles more evenly in the frame 1. The synchronous belt 403 and the synchronous wheel 402 work together to make the rotating shaft 401 rotate synchronously when the reciprocating screw 301 rotates. This allows the discharge pipe 2 to move back and forth to discharge material while the blade 4 disperses it, thus making the hot melt adhesive particles more dispersed in the frame.
[0021] Reference Figure 1-2 A water-cooled box 5 is installed on the lower side of the frame 1. The water-cooled box 5 is equipped with water-cooling pipes and a guide fan to cool the air. A set of cooling holes 6 is opened on the lower end face of the frame 1 corresponding to the position of the water-cooled box 5. The size of the cooling holes 6 is smaller than the size of the hot melt adhesive particles, so as to prevent the hot melt adhesive particles from entering the water-cooled box 5 and causing damage. Cold air enters the frame 1 through the cooling holes 6. A vibrating screen 7 is installed on the lower end face of the frame 1 corresponding to the position of the blade plate 4. A set of vibrating motors is installed on the lower side of the vibrating screen 7. The vibrating motors are OLI-MVE series micro brushless motors. The vibrating screen 7 can screen the hot melt adhesive particles, thereby screening out any debris that may be present in the hot melt adhesive particles. An insert frame 8 is installed on the lower side of the vibrating screen 7. A collection box 801 is inserted into the inner side of the insert frame 8. The inner wall surfaces of both are covered with a smooth layer to facilitate the sliding and pulling of the collection box 801. The collection box 801 corresponds to the size and position of the vibrating screen 7. The screened debris enters the collection box 801 for collection.
[0022] Based on the above structure, the present invention has the following embodiments: Under the influence of gravity, the hot melt adhesive particles move along the frame 1. When they reach the effective range of the cooling holes 6, the cold air generated by the water-cooled box 5 enters the frame 1 through the cooling holes 6, thereby cooling the hot melt adhesive particles. At the same time, the hot melt adhesive particles are relatively dispersed in the frame 1, which allows the hot melt adhesive particles to be fully cooled. Before the hot melt adhesive particles enter the effective range of the cooling holes 6, the vibrating screen 7 can screen the hot melt adhesive particles to remove any debris that may be present in the hot melt adhesive particles, thus preventing the debris from affecting the subsequent cooling process.
[0023] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
[0024] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
