Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive processing, in particular to a drying box for hot melt adhesive production which is convenient for discharging materials. Background Art

[0002] Hot melt adhesive is a plastic adhesive whose physical state changes with temperature within a certain temperature range. It is solid at room temperature, and becomes a flowable liquid with a certain viscosity when heated and melted to a certain temperature. Hot melt adhesive is composed of basic resin, tackifier, viscosity regulator and antioxidant. After the hot melt adhesive is produced, it is generally granular and contains a small amount of water. It needs to be dried. During the drying process, it is necessary to pay attention to the drying time and the uniformity of the drying. The existing drying process is to directly place the hot melt adhesive particles in a drying oven to dry. Although some drying ovens have a stirring function to tumble and stir the hot melt adhesive particles, the existing stirring device cannot reach the dead corners when stirring in the box, and cannot work on the hot melt adhesive particle blocks that are adhered together due to uneven drying. These blocks often adhere to the dead corners, affecting the discharge. For this reason, a drying oven for hot melt adhesive production that is easy to discharge is proposed. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] A drying box for hot melt adhesive production that facilitates material discharge is described below in conjunction with the accompanying drawings in some embodiments of the present invention.

[0022] Example:

[0023] Combination Figure 1-5As shown, the utility model provides a drying box for hot melt adhesive production that is convenient for discharging, including a drying box 1, a CNC system 2 is fixedly installed on the surface of the drying box 1, a box door 3 is movably installed on one side of the drying box 1, a slide is arranged inside the drying box 1, a collecting box 4 is slidably connected to the slide, and the collecting box 4 is used to collect the hot melt adhesive particles that have been dried, so as to facilitate subsequent processing, a servo motor 5 is fixedly installed on the top of the inner wall of the drying box 1, a transmission gear 6 is fixedly installed on the transmission end of the servo motor 5, the servo motor 5 can drive the transmission gear 6 to rotate horizontally, the tooth surface of the transmission gear 6 is meshed with a first bevel gear 7, and when the servo motor 5 drives the transmission gear 6 to rotate, it can synchronously transmit the transmission to the first bevel gear 7. A bevel gear 7 is used to make the first bevel gear 7 rotate in a vertical direction. A rotating shaft 8 is fixedly sleeved in the middle of the first bevel gear 7. A first bearing 9 is fixedly installed at one end of the rotating shaft 8. When the first bevel gear 7 synchronously drives the rotating shaft 8 to rotate, the first bearing 9 fixed at one end of the rotating shaft 8 can provide a stable rotation environment for the rotating shaft 8 to avoid the device from stopping due to jamming. A stirring knife group 10 is fixedly installed in the middle of the rotating shaft 8. The stirring knife group 10 can fully stir and break up the hot melt adhesive particles to avoid sticking together and affecting the discharge. A second bearing 11 is fixedly installed at the other end of the rotating shaft 8. The second bearing 11 has the same function as the first bearing 9, and is used to stabilize the rotation of the rotating shaft 8, so that the rotating shaft 8 can rotate more smoothly. To make the gear 6 smoother, a second bevel gear 12 is meshed on the tooth surface of the transmission gear 6, and the middle of the second bevel gear 12 is movably sleeved with the rotating shaft 8, that is, the second bevel gear 12 is sleeved on the rotating shaft 8. When the rotating shaft 8 rotates, it will not drive the second bevel gear 12 to rotate in the same direction. When the transmission gear 6 rotates, the first bevel gear 7 and the second bevel gear 12 will rotate relative to each other to avoid the same-direction rotation affecting the operation of the device. A cover net 13 is fixedly installed on one side of the second bevel gear 12, and a reinforcement piece 14 is attached to one side of the cover net 13. The cover net 13 can discharge the dried water in time to prevent the hot melt adhesive from being contaminated with water again. The reinforcement piece 14 plays a fixing role. The outside of the mixing knife group 10 is sleeved with a roller 15. The inside of the drum 15 is fixedly installed with convex teeth 16, and the inside of the drum 15 is used to put hot melt adhesive particles, and the hot melt adhesive is centrally processed to avoid scattering in the dead corners of the device and being difficult to dry. The convex teeth 16 can cooperate with the stirring knife group 10 to continuously break up the hot melt adhesive blocks that are stuck together, and increase the contact area with the hot melt adhesive to achieve rapid drying. The top of the drum 15 is fixedly installed with a hinge 17, and a feed cover 18 is fixedly installed on one side of the hinge 17. The feed cover 18 can be rotated around the hinge 17 to open, and the surface of the feed cover 18 is also fixedly installed with convex teeth 16 to avoid empty positions affecting the discharge of materials. The surface of the drum 15 is clamped with a stop cap 19, and the stop cap 19 is used to control the opening and closing of the feed cover 18.The feed cover 18 can be fastened to the surface of the drum 15 by rotating the stop cap 19 to seal the drum 15. The surface of the servo motor 5 is sleeved with a protective shell 20. The servo motor 5, the transmission gear 6, the first bevel gear 7 and the second bevel gear 12 are placed inside the protective shell 20 to protect these parts from damage.

[0024] The working principle and use process of the utility model are as follows: first, by rotating the stop cap 19, the feed cover 18 can be rotated around the hinge 17 to open. At this time, the undried hot melt adhesive particles are placed in the drum 15, and then the feed cover 18 is rotated and closed. The rotating stop cap 19 fixes the feed cover 18 and the drum 15. At this time, the servo motor 5 is started to rotate the transmission gear 6, which synchronously drives the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 can drive the rotating shaft 8 to rotate. At this time, the stirring knife group 10 sleeved on the rotating shaft 8 rotates. In the same process, the transmission gear 6 synchronously drives the second bevel gear 12 to rotate in the opposite direction. At this time, the second bevel gear 12 drives the drum 15 to rotate, and the hot melt adhesive particles inside the drum 15 are continuously rolled. The synchronous stirring knife group 10 and the drum 15 work in the same direction. Under the action of the convex teeth 16, the hot melt adhesive particles are broken up and dried.

[0025] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
