Description

Technical Field

[0001] The utility model relates to the technical field of hot melt adhesive cooling, in particular to hot melt adhesive cooling equipment. Background Art

[0002] Hot melt adhesive is a plastic adhesive that is solid at room temperature and can quickly bond after being heated and melted. Hot melt adhesive products are mostly in the form of blocks, rods or granules. For granular hot melt adhesive, the hot melt adhesive raw materials must first be heated and stirred in a reactor, and then the heated and mixed hot melt adhesive raw materials are filtered and extruded from a molding die into long strips. The long hot melt adhesive strips are cooled and solidified in the coolant of a cooling tank and then cut into granules by a pelletizer to obtain rubber pellets.

[0003] In order to improve the production efficiency of long strip extrusion, the molding die can extrude multiple hot melt adhesive strips at the same time. However, the multiple hot melt adhesive strips leaving the molding die are relatively dense and have less gaps between them. After the coolant enters the cooling tank, less coolant enters between the hot melt adhesive strips, resulting in insufficient cooling effect of the hot melt adhesive strips. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical ideas claimed for protection by the present invention. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0025] like Figures 1 to 6 As shown, a hot melt adhesive cooling device in an embodiment of the utility model comprises a cooling groove 1 extending from front to back and a plurality of partition components 2 spaced from the front to the right in the cooling groove 1, wherein the cooling groove 1 is filled with a coolant for cooling the hot melt adhesive strips. In fact, the coolant in the utility model embodiment can be water, and the plurality of hot melt adhesive strips leaving the external molding mold can be immersed in the coolant in the cooling groove 1 to achieve cooling and solidification of the long hot melt adhesive strips.

[0026] The partition assembly 2 includes two partition frames 3 arranged at intervals in front and back and completely immersed in the coolant. In fact, the partition frame 3 can be fixedly connected to the cooling tank 1 or detachably connected to the cooling tank 1 by plugging in a slot. The partition frame 3 includes a plurality of vertical bars 4 arranged at intervals in the left and right directions and a plurality of horizontal bars 5 connecting two adjacent vertical bars 4. Figure 4 As shown, the front horizontal bars 5 of the front partition frame 3 are arranged in sequence from left to right on the front partition frame 3 in an up-down and up-down cycle, such as Figure 5 As shown, the plurality of horizontal bars 5 of the rear partition frame 3 are arranged sequentially from left to right on the rear partition frame 3 in a downward, upward and downward cycle.

[0027] The specific working principle of a hot-melt adhesive cooling device of the utility model is as follows: a plurality of hot-melt adhesive strips leaving an external molding mold are spaced from left to right under the action of a plurality of vertical strips 4 of a partition frame 3, thereby increasing the gap between two adjacent hot-melt adhesive strips and causing each hot-melt adhesive strip to produce an up-and-down or down-and-down-up cyclic fluctuation on the left and right of the horizontal strips 5, thereby increasing the total length of the hot-melt adhesive strips immersed in the coolant and enhancing the cooling effect of the hot-melt adhesive strips.

[0028] like Figure 6 As shown, the solid line is the first hot melt adhesive strip on the left, and the dotted line is the second hot melt adhesive strip on the left. The first hot melt adhesive strip on the left produces an up-and-down, up-and-down cycle, while the second hot melt adhesive strip on the left produces an up-and-down, up-and-down cycle, which makes the gap between the two adjacent hot melt adhesive strips larger, providing more coolant for heat exchange, thereby enhancing the cooling effect of the hot melt adhesive strips.

[0029] A hot melt adhesive cooling device of the utility model can increase the gap space between two adjacent hot melt adhesives and increase the total length of the hot melt adhesive immersed in the coolant through the cooperation of a cooling groove 1, a partition assembly 2, a partition frame 3, a vertical bar 4 and a horizontal bar 5, so as to enhance the cooling effect of the hot melt adhesive strip.

[0030] Specifically, the cross-sections of the vertical strips 4 and the horizontal strips 5 are preferably circular, which makes it more difficult to break the hot-melt adhesive strip compared to a polygon with sharp corners, thereby reducing the probability of breaking the hot-melt adhesive strip.

[0031] More specifically, the spacing between the upper horizontal bar 5 and the upper ends of the vertical bars 4 and the spacing between the lower horizontal bar 5 and the lower ends of the vertical bars 4 are preferably larger than the outer diameter of the hot-melt adhesive strip. In fact, the upper horizontal bar 5 and the vertical bars 4 on the left and right sides form an upper limit groove which opens upward and is used to limit the left-right swing range of the hot-melt adhesive strip, so as to reduce the probability of the hot-melt adhesive leaving the upper limit groove upward; the lower horizontal bar 5 and the vertical bars 4 on the left and right sides form a lower limit groove which opens downward and is used to limit the left-right swing range of the hot-melt adhesive strip, so as to reduce the probability of the hot-melt adhesive leaving the lower limit groove downward.

[0032] It should be noted that the spacing between two adjacent vertical bars 4 is preferably greater than twice the outer diameter of the hot-melt adhesive strip to reduce the probability of two adjacent hot-melt adhesive strips contacting each other due to left and right movement. The spacing between the upper horizontal bar 5 and the lower horizontal bar 5 is preferably greater than half the length of the vertical bar 4 to ensure the amplitude of the up and down fluctuation of the hot-melt adhesive strip and ensure the cooling effect of the hot-melt adhesive strip.

[0033] In this embodiment, the hot melt adhesive cooling device of the utility model also preferably includes a circulating refrigeration device 6 for reducing the temperature of the coolant. In fact, the circulating refrigeration device 6 may include a refrigeration mechanism and a circulating pump, which can suck the coolant in the cooling tank 1, cool the coolant, and pump the coolant back into the cooling tank 1; the cooling tank 1 is provided with a liquid outlet 7 and multiple groups of liquid inlets 8, the liquid outlet 7 is located higher than the upper horizontal bar 5 and is connected to the suction port of the circulating refrigeration device 6, and multiple groups of the liquid inlets 8 are arranged one by one at the bottom of the cooling tank 1 corresponding to the middle of the multiple groups of partition components 2 and are connected to the pump outlet of the circulating refrigeration device 6. Since the gap between the two adjacent hot melt adhesive strips located in the middle of the partition component 2 is the largest, the coolant enters from the bottom of the cooling tank 1 and leaves from the upper horizontal bar 5, ensuring that the coolant flows from bottom to top and contacts the hot melt adhesive strips, thereby ensuring the cooling effect of the hot melt adhesive strips.

[0034] Specifically, the plurality of groups of liquid inlets 8 preferably include a plurality of liquid spray ports 9 that are spaced apart from each other and are arranged in a left-right and right-center manner corresponding to the plurality of vertical strips 4, so that the coolant can pass from bottom to top between two adjacent hot-melt adhesive strips, thereby reducing the resistance of the coolant. More specifically, the liquid spray ports 9 are preferably long through holes extending forward and backward, so that the coolant entering the cooling tank 1 through the liquid spray ports 9 is in a strip shape, thereby increasing the contact area between the coolant passing through the two adjacent hot-melt adhesive strips and the hot-melt adhesive strips, thereby improving the cooling effect.

[0035] It is worth mentioning that the left and right sides of the partition frame 3 are preferably provided with connecting shafts 10 rotatably connected to the cold tank, and the connecting shaft 10 on the left or right side of the partition frame 3 is preferably installed with an adjustment device 11 for changing the swing angle of the partition frame 3. In fact, the adjustment device 11 can be a lockable turntable or a servo motor and a linkage mechanism connecting the power transmission end of the servo motor and the connecting shaft 10. By adjusting the angle of the partition frame 3, the vertical distance between the upper horizontal bar 5 and the lower horizontal bar 5 can be changed to adjust the amplitude of the ups and downs of the hot melt adhesive strip, thereby adjusting the total length of the hot melt adhesive strip immersed in the coolant.

[0036] Specifically, the adjustment device 11 preferably includes a swing arm 12 fixed on the rotating shaft and perpendicular to the vertical bar 4, and a locking mechanism 13 for locking the position of the swing arm 12 and the cooling groove 1. The locking mechanism 13 can be a caliper or an opening and closing cylinder. When the swing arm 12 drives the partition frame 3 to rotate to the desired angle, the locking mechanism 13 fixes the swing arm 12 to fix the partition frame 3.

[0037] More specifically, the locking mechanism 13 preferably includes a locking bolt 14 and a fixing plate 15 fixed to the left or right side of the cooling tank 1, the fixing plate 15 is provided with a circular arc groove 16 arranged concentrically with the connecting shaft 10, and the locking bolt 14 passes through the circular arc groove 16 and is threadedly connected to the swing arm 12. In fact, the head of the locking bolt 14 is larger than the width of the circular arc groove 16, and the stud of the locking bolt 14 is smaller than the width of the circular arc groove 16. When the position of the swing arm 12 needs to be fixed, the stud of the locking bolt 14 passes through the circular arc groove 16 and is threadedly connected to the swing arm 12, so that the head of the locking bolt 14 presses the fixing plate 15, thereby fixing the position of the swing arm 12; when the angle of the swing arm 12 needs to be adjusted, the locking bolt 14 is rotated to press the corresponding fixing plate 15.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
