Description

Technical Field

[0001] The utility model relates to the field of hot melt adhesives, and more particularly to an easily moldable hot melt adhesive device. Background Art

[0002] Hot melt adhesive is a plastic adhesive that is solid at room temperature and quickly bonds when heated and melted. In practice, hot melt adhesive is heated until it melts, applied to the object to be bonded, and then allowed to sit for a while until the melted hot melt adhesive solidifies again, completing the bonding. However, during this period, hot melt adhesive can accidentally touch the adhesive or the object to be bonded, resulting in bond failure. Therefore, a device is needed to quickly cool and shape the hot melt adhesive. Utility Model Content

[0003] The utility model provides an easy-to-shape hot melt adhesive device, which can quickly cool and shape the hot melt adhesive.

[0004] The technical solution adopted by the present invention to solve the above problems is:

[0005] A hot melt adhesive device that is easy to form includes a forming arc plate and a conveying pipe arranged at the rear end of the forming arc plate. A heating cavity tube is coaxially extended from the upper end of the conveying pipe. The heating cavity tube heats and melts the hot melt adhesive particles, which then flow into the forming arc plate through the conveying pipe to contact the adhesive object. As the forming arc plate moves axially backward, a continuous convex arc-shaped hot melt adhesive seam appears on the surface of the adhesive object. A cooling box filled with coolant is provided on the upper part of the rear end of the forming arc plate for quickly cooling and forming the hot melt adhesive at the front of the forming arc plate.

[0006] The delivery pipe is arranged to be tilted backward.

[0007] The upper portion of the heating cavity tube is connected to a filler cavity.

[0008] A spiral rack is rotated in the heating cavity tube.

[0009] A liquid storage box is fixed at the front end of the filling cavity. A micro pump is installed near the filling cavity. The micro pump is connected to the rear end of the cooling box. The front end of the liquid storage box is connected to the front end of the cooling box through a support pipe.

[0010] The liquid storage box is in the shape of a circular tube and is parallel to the axis of the formed arc plate.

[0011] The support pipe is vertically arranged between the liquid storage box and the cooling box.

[0012] A liquid changing port is provided at the upper front end of the liquid storage box.

[0013] The internal thread of the liquid exchange port is provided with a plug.

[0014] The surface of the liquid storage box is provided with anti-skid cotton. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 and Figure 2 It is a structural diagram of an easy-to-form hot melt adhesive device;

[0016] Figure 3 It is a schematic diagram of the cross-sectional structure of the easy-to-form hot melt adhesive device.

[0017] In the picture:

[0018] Forming arc plate 1; delivery pipe 2; heating cavity tube 3; filler cavity 4; spiral frame 5; cooling box 6; liquid storage box 7; support tube 8; micro pump 9; liquid exchange port 10; plug 11. DETAILED DESCRIPTION

[0019] The following combination Figure 1-3 To explain:

[0020] A hot melt adhesive device that is easy to form includes a forming arc plate 1 and a conveying pipe 2 arranged at the rear end of the forming arc plate 1. A heating cavity tube 3 is coaxially extended from the upper end of the conveying pipe 2. The heating cavity tube 3 heats and melts the hot melt adhesive particles, which then flow into the forming arc plate 1 through the conveying pipe 2 and come into contact with the adhesive object. As the forming arc plate 1 moves axially backward, a continuous convex arc-shaped hot melt adhesive seam appears on the surface of the adhesive object. A cooling box 6 filled with coolant is provided at the upper part of the rear end of the forming arc plate 1 for quickly cooling and forming the hot melt adhesive at the front of the forming arc plate 1.

[0021] During use, hot melt adhesive particles are added into the heating cavity tube 3 and heated to a melted state, and then flow into the forming arc plate 1 through the delivery tube 2 and contact the bonding object. As the forming arc plate 1 moves axially backward, a continuous convex arc-shaped hot melt adhesive seam appears on the surface of the bonding object. During this process, the hot melt adhesive flows into the forming arc plate 1 from the delivery tube 2, and as the forming arc plate 1 moves, the hot melt adhesive is adhered to the object to be bonded in the forming arc plate 1 and remains stationary, so that the cooling box 6 contacts the adhesive liquid at this location, thereby cooling the adhesive liquid and causing it to cool and form quickly, thereby forming a convex arc-shaped hot melt adhesive seam that slides out directly from the front end of the forming arc plate 1 when the device is bonding.

[0022] Further:

[0023] The delivery pipe 2 is tilted backward, and a filler cavity 4 is connected to the upper portion of the heating cavity 3 ; a spiral frame 5 rotates inside the heating cavity 3 .

[0024] The filling cavity 4 is used to add hot-melt glue particles. The hot-melt glue particles in the filling cavity 4 automatically fall into the heating cavity tube 3 for heating due to their own gravity. The spiral frame 5 is driven by a micro motor installed at the rear end of the heating cavity tube 3, so that the spiral frame 5 rotates in the heating cavity tube 3, thereby squeezing and transporting the glue in the heating cavity tube 3 to the delivery pipe 2, and the delivery pipe 2 is tilted backward, so that the glue liquid can more easily push the forming arc plate 1 to move backward after passing through the delivery pipe 2 into the forming arc plate 1.

[0025] like Figure 1-3 As shown:

[0026] A liquid storage box 7 is fixed to the front end of the filling cavity 4. A micro pump 9 is installed near the filling cavity 4. The micro pump 9 is connected to the rear end of the cooling box 6. The front end of the liquid storage box 7 is connected to the front end of the cooling box 6 through a support pipe 8.

[0027] The coolant in the liquid storage tank 7 is transported to the cooling box 6 by the micro pump 9, and then flows back to the liquid storage tank 7 from the front end of the cooling box 6 through the support pipe 8, forming a circulation of the coolant in the cooling box 6 to ensure the cooling effect of the cooling box 6.

[0028] At the same time, the liquid storage box 7 is in a circular tubular shape and is parallel to the axis of the formed arc plate 1. When using the device, the device can be picked up and used by holding the liquid storage box 7;

[0029] Moreover, by providing anti-slip cotton on the surface of the liquid storage box 7, I can wipe more comfortably;

[0030] At the same time, the support tube 8 is vertically arranged between the liquid tank 7 and the cooling tank 6 to form a supporting connection between the liquid tank 7 and the cooling tank 6. While ensuring the circulation flow of cooling, the overall structure of the device is ensured to be firm, which is convenient for pressing the device down and ensuring the shape of the glue seam.

[0031] like Figure 1-3 As shown:

[0032] A liquid exchange port 10 is provided at the upper front end of the liquid storage box 7, which is convenient for pouring out or introducing the coolant, and thus convenient for replacing the coolant; and a plug 11 is installed through the internal thread of the liquid exchange port 10 to seal the liquid exchange port 10.
