A film package hot melt adhesive cooling device

Abstract

The present invention relates to the technical field of hot melt adhesive production equipment, and more specifically, to a film-wrapped hot melt adhesive cooling device, comprising a cooling pool and a guide mechanism. The guide mechanism is immersed below the liquid level of the cooling pool. The guide mechanism is also provided with a driving mechanism for driving it to move. When in use, the molten hot melt adhesive loaded into the film bag enters the cooling pool. The hot melt adhesive entering the cooling pool is then placed under the guide mechanism and then immersed in the coolant. Driven by the driving mechanism, the guide mechanism gradually pushes the hot melt adhesive forward and finally outputs it from the other end of the guide mechanism. Since the guide mechanism is immersed in the coolant, the hot melt adhesive block is cooled in an immersed state. This prevents the hot melt adhesive from partially floating above the liquid surface and being unable to cool quickly.

Description

Technical Field

[0001] The present invention relates to the technical field of hot melt adhesive production equipment, and in particular to a film package hot melt adhesive cooling device. Background Art

[0002] After the hot melt adhesive is produced, it is in a molten state. After being poured into a film bag, it is placed in water to cool and harden. Finally, the hardened hot melt adhesive is dried and packaged into a finished product. This kind of hot melt adhesive product is called film-wrapped hot melt adhesive.

[0003] In the prior art, the cooling of film-wrapped hot melt adhesive is generally done by setting up a relatively long (more than ten meters) water tank, and the cooling water flows slowly in one direction. After the hot melt adhesive falls into the water, it flows down with the water until it reaches the end of the water tank. Since the hot melt adhesive floats on the water surface and cannot be completely in contact with the water, the cooling effect is weak, and a relatively long water tank is required. At the same time, the faster the water flow speed in the water tank, the better the cooling, but the faster the water flow speed will cause the product to flow away quickly, and the cooling time will be insufficient. Lengthening the water tank is the best way to solve this contradiction. In summary, the existing cooling method takes up space and the effect needs to be improved. Summary of the invention

[0004] The object of the present invention is to provide a film package hot melt adhesive cooling device, which can immerse the hot melt adhesive in a cooling liquid, thereby improving the cooling efficiency.

[0005] The present invention is achieved through the following technical solutions:

[0006] A film package hot melt adhesive cooling device comprises a cooling pool and a flow guiding mechanism; the flow guiding mechanism is immersed below the liquid level of the cooling pool; the flow guiding mechanism is also provided with a driving mechanism for driving the flow guiding mechanism to move.

[0007] Furthermore, it also includes a shaping mechanism; the shaping mechanism includes a guide conveyor belt and a pressure plate conveyor belt; a plurality of shaping grooves are arranged on the surface of the guide conveyor belt along its length direction; the pressure plate conveyor belt is arranged in cooperation with the guide conveyor belt so that the pressure plate conveyor belt is pressed against the guide conveyor belt and covers the opening of the shaping groove; the guide conveyor belt and the pressure plate conveyor belt extend from above the liquid surface to below the liquid surface; the end of the shaping mechanism is connected to the front end of the guide conveyor belt.

[0008] Furthermore, the guide conveyor belt includes a plurality of chain plates hinged to each other, so that the plurality of chain plates are connected in a ring shape; a plurality of end plates are evenly distributed along the length direction of the guide conveyor belt; the end plates are connected to the chain plates; two side plates are also arranged between adjacent end plates; the two side plates are connected to the two sides of a chain plate between the two end plates, so that the side plates, chain plates and end plates form the shaping groove.

[0009] Furthermore, the guide mechanism includes a plurality of guide rollers; the plurality of guide rollers are distributed in a straight line; and the diameter of the guide roller is 1.2 times the length of the shaping groove.

[0010] Furthermore, it also includes a drainage mechanism; the drainage mechanism includes a plurality of drainage rollers; the plurality of drainage rollers are distributed in a straight line; the diameter of the drainage roller is 1.2 times the length of the shaping groove; the end of the guide mechanism and the starting end of the drainage mechanism are cooperated with a salvage mechanism to enable the material at the end of the guide mechanism to be salvaged to the starting end of the drainage mechanism through the salvage mechanism.

[0011] Furthermore, the drainage mechanism is arranged directly above the flow guiding mechanism; and a hair dryer is also arranged above the drainage mechanism.

[0012] Furthermore, the salvage mechanism is in the shape of a drum; a plurality of salvage grooves are arranged on the surface of the salvage mechanism along its circumference.

[0013] Furthermore, a water inlet is provided at the bottom of the cooling pool; the water inlet is vertically arranged upward at the end of the flow guide mechanism.

[0014] Furthermore, the guide conveyor belt and the pressure plate conveyor belt are both provided with tensioning rollers to enable the guide conveyor belt and the pressure plate conveyor belt to be tensioned against each other.

[0015] Furthermore, the flow guiding mechanism is arranged to be inclined from bottom to top.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0017] When the film package hot melt adhesive cooling device of the present invention is used, the molten hot melt adhesive loaded into the film bag enters the cooling pool. Then the hot melt adhesive entering the cooling pool is placed under the guide mechanism and then immersed in the cooling liquid. The guide mechanism is driven by the driving mechanism to gradually push the hot melt adhesive forward and finally output from the other end of the guide mechanism.

[0018] Since the guide mechanism is immersed in the coolant, the hot melt adhesive block is cooled while immersed. This prevents the hot melt adhesive from floating above the liquid surface and failing to cool quickly. In addition, the driving speed of the guide mechanism can be set as needed. As a result, the time for the hot melt adhesive to flow through the cooling pool can be adjusted as needed. The hot melt adhesive floats to the surface after cooling in the coolant. This greatly reduces the length of the cooling pool and the floor space of the equipment.

[0019] Before the hot melt adhesive enters the cooling pool, it first enters the shaping groove of a shaping mechanism. Then the guide conveyor belt and the pressure plate conveyor cooperate with each other. Then the hot melt adhesive is pressed tightly inside the shaping groove, and then the hot melt adhesive is shaped. In order to facilitate packaging, the hot melt adhesive is generally shaped into a rectangular parallelepiped. The guide conveyor belt is made of chain plates. The shaping groove is surrounded by two end plates and two side plates. When the guide conveyor belt is tensioned in a straight state, the shaping groove is spliced ​​into a closed state. When the guide conveyor belt passes through the round rollers at both ends, the two end plates are in an open state. This makes it easy to put the packaged hot melt adhesive between the two end plates. Then the shaping groove gradually enters under the pressure plate conveyor belt, and then the hot melt adhesive is gradually squeezed into a rectangular parallelepiped under the pressure of the pressure plate conveyor belt. Then the shaping is completed. Then the hot melt adhesive enters the coolant along the guide conveyor belt, so that the surface of the hot melt adhesive is cooled and hardened. This fixes the shape of the hot melt adhesive. When the guide conveyor belt moves to the round roller at the end, the two end plates open again. This allows the hot melt adhesive to easily fall out of the shaping groove. After the hot melt adhesive is fixed in shape by the shaping groove, it enters the guide mechanism for further cooling, so that the adhesive liquid at the center of the hot melt adhesive is cooled and solidified. This completes the entire cooling process of the hot melt adhesive.

[0020] The guide mechanism is provided in the form of a guide roller, and the diameter of the guide roller is 1.2 times the length of the shaping groove. This allows the hot melt adhesive block shaped by the shaping groove to be turned over under the action of the two guide rollers when entering between two adjacent guide rollers. This allows the hot melt adhesive to better exchange heat with the coolant during the turning process, thereby improving the cooling efficiency.

[0021] The drain mechanism is provided so that the water on the surface of the hot melt adhesive falls into the cooling pool through the gaps between the drain rollers when the hot melt adhesive moves. This allows the draining and cooling to be located at the same location, thus avoiding more space occupation. At the same time, the principle of the drain rollers is the same as that between the guide rollers. The hot melt adhesive will also flip when passing through the drain rollers. A hair dryer is provided above the drain mechanism to dry the hot melt adhesive during the flipping process, thereby enabling rapid drying.

[0022] The outlet of the shaping mechanism is located at the center of the beginning of the flow guide mechanism, that is, the shaped hot melt adhesive is gathered in the middle of the flow guide mechanism, in order to disperse these hot melt adhesive blocks to both sides. A water inlet is set below the outlet of the shaping mechanism. When the coolant enters the cooling pool through the water inlet, the water flows through the water inlet to diffuse around, thereby causing some hot melt adhesive to be dispersed on both sides of the flow guide mechanism.

[0023] The diversion mechanism is tilted from bottom to top so that the hot melt adhesive is first cooled in the deep water area and gradually moves to the shallow water area. Since cooling is mostly done in the shallow water area, the temperature in the deep water area is lower than that in the shallow water area. In other words, the hot melt adhesive block is first cooled in the deep water area with lower temperature and gradually moves to the shallow water area with higher temperature, finally achieving a good cooling effect.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Example:

[0034] like Figure 1-Figure 4As shown, the present invention provides a film package hot melt adhesive cooling device, comprising a cooling pool 1 and a flow guiding mechanism. The flow guiding mechanism is immersed below the liquid level of the cooling pool 1. The flow guiding mechanism is also provided with a driving mechanism for driving the flow guiding mechanism to move.

[0035] When the film package hot melt adhesive cooling device of the present invention is used, the molten hot melt adhesive in the film bag enters the cooling pool 1. Then the hot melt adhesive entering the cooling pool 1 is placed under the guide mechanism and then immersed in the coolant. The guide mechanism gradually pushes the hot melt adhesive forward under the drive mechanism and finally outputs it from the other end of the guide mechanism.

[0036] Since the flow guide mechanism is immersed in the coolant, the hot melt adhesive block 15 is cooled in an immersed state. This prevents the hot melt adhesive from floating above the liquid surface and failing to cool quickly. In addition, the driving speed of the flow guide mechanism can be set as needed. As a result, the time for the hot melt adhesive to flow through the cooling pool 1 can be adjusted as needed. It floats to the surface after cooling in the coolant. This greatly reduces the length of the cooling pool 1 and reduces the floor space of the equipment.

[0037] In this embodiment, a shaping mechanism is also included. The shaping mechanism includes a guide conveyor belt 2 and a pressure plate conveyor belt 3. Figure 3 As shown, the surface of the guide conveyor belt 2 is provided with a plurality of shaping grooves along its length direction. The pressure plate conveyor belt 3 is arranged in cooperation with the guide conveyor belt 2 so that the pressure plate conveyor belt 3 is pressed against the guide conveyor belt 2 and covers the opening of the shaping groove. The guide conveyor belt 2 and the pressure plate conveyor belt 3 move synchronously. The guide conveyor belt 2 and the pressure plate conveyor belt 3 extend from above the liquid surface to below the liquid surface, and then gradually convey the hot melt adhesive block 15 inside the shaping groove to below the liquid surface for preliminary cooling. The end of the shaping mechanism is connected to the front end of the guide conveyor end.

[0038] In this embodiment, the guide conveyor belt 2 includes a plurality of chain plates 4 that are hinged to each other, so that the plurality of chain plates 4 are connected to form a ring. Figure 3 As shown. A number of end plates 5 are evenly distributed along the length direction of the guide conveyor belt 2. The end plates 5 are connected to the chain plates 4. Two side plates 6 are also arranged between adjacent end plates 5. The two side plates 6 are connected to the two sides of any chain plate 4 between the two end plates 5 so that the side plates 6, the chain plates 4 and the end plates 5 form a shaping groove. When the guide conveyor belt 2 is tensioned in a straight line state, the two end plates 5 and the two side plates 6 form a rectangular shape. When the guide conveyor belt 2 is rolled, the panel is tensioned into an arc shape. At this time, the two adjacent end plates 5 are separated at an angle to facilitate the insertion and removal of the hot melt adhesive.

[0039] Before the hot melt adhesive enters the cooling pool 1, it first enters the shaping groove of a shaping mechanism. Then the guide conveyor belt 2 and the pressure plate conveyor cooperate with each other. Then the hot melt adhesive is pressed tightly inside the shaping groove, and then the hot melt adhesive is shaped. In order to facilitate packaging, the hot melt adhesive is generally shaped into a rectangular parallelepiped. The guide conveyor belt 2 is made of a chain plate 4. The shaping groove is surrounded by two end plates 5 and two side plates 6. When the guide conveyor belt 2 is tensioned in a straight state, the shaping groove is spliced ​​into a closed state. When the guide conveyor belt 2 passes through the round rollers 14 at both ends, the two end plates 5 are in an open state. This makes it easy to put the packaged hot melt adhesive between the two end plates 5. Then the shaping groove gradually enters under the pressure plate conveyor belt 3, and then the hot melt adhesive is gradually squeezed into a rectangular parallelepiped under the pressure of the pressure plate conveyor belt 3. Then the shaping is completed. Then the hot melt adhesive enters the coolant along with the guide conveyor belt 2 to cool and harden the surface of the hot melt adhesive. This fixes the shape of the hot melt adhesive. When the guide conveyor belt 2 moves to the round roller 14 at the end, the two end plates 5 are opened again. This allows the hot melt adhesive to easily fall out of the shaping groove. After the hot melt adhesive is fixed in shape by the shaping groove, it enters the guide mechanism for further cooling, so that the adhesive liquid at the center of the hot melt adhesive is cooled and solidified. This completes the entire cooling process of the hot melt adhesive.

[0040] In this embodiment, the guide mechanism includes a plurality of guide rollers 7. Figure 1 As shown, several guide rollers 7 are distributed in a straight line. The diameter of the guide roller 7 is 1.2 times the length of the shaping groove. Figures 4 to 6 As shown, the first surface of the hot melt adhesive block 15 first contacts the first guide roller 7 and moves toward the second guide roller 7 under the action of the first guide roller 7. Under the action of buoyancy, the hot melt adhesive block 15 tilts upward as much as possible, so that the hot melt adhesive block 15 is in a Figure 5 Then, when the hot melt adhesive block 15 contacts the second guide roller 7, it moves forward under the action of the second guide roller 7 and contacts the second guide roller 7 with the second surface. This also completes the turning of the hot melt adhesive block 15. The hot melt adhesive block 15 cooperates with other guide rollers 7 in the same process.

[0041] The guide mechanism is provided in the form of a guide roller 7, and the diameter of the guide roller 7 is 1.2 times the length of the shaping groove. This allows the hot melt adhesive block 15 after shaping the shaping groove to be turned over under the action of the two guide rollers 7 when entering between two adjacent guide rollers 7. In this way, the hot melt adhesive can better exchange heat with the coolant during the turning process, thereby improving the cooling efficiency.

[0042] In this embodiment, a drain mechanism is also included. The drain mechanism includes a plurality of drain rollers 8. The plurality of drain rollers 8 are distributed in a straight line. The diameter of the drain roller 8 is 1.2 times the length of the shaping groove. The matching process between the drain roller 8 and the hot melt adhesive block 15 is the same as the matching process between the guide roller 7 and the hot melt adhesive block 15. A salvaging mechanism 9 is provided at the end of the guide mechanism and the starting end of the drain mechanism, so that the material at the end of the guide mechanism can be salvaged to the starting end of the drain mechanism through the salvaging mechanism 9.

[0043] In this embodiment, the water draining mechanism is arranged directly above the flow guiding mechanism. A hair dryer 10 is also arranged above the water draining mechanism.

[0044] The drain mechanism is provided so that the water on the surface of the hot melt adhesive can fall into the cooling pool 1 through the gaps between the drain rollers when the hot melt adhesive moves. Thus, the draining and cooling are located at the same position, avoiding more space occupation. At the same time, the principle of the drain rollers 8 is the same as that between the guide rollers 7. The hot melt adhesive will also turn over when passing through the drain rollers 8. A hair dryer 10 is provided above the drain mechanism so that the hot melt adhesive can be dried during the turning process, thereby being able to dry quickly.

[0045] In this embodiment, the salvage mechanism 9 is in the shape of a drum. The surface of the salvage mechanism 9 is provided with a plurality of salvage grooves 11 along its circumference. Figure 1 As shown, when the salvaging mechanism 9 rotates counterclockwise, the cooled hot melt adhesive block 15 can be scooped up and poured out to the drain roller 8 at the drain roller 8 .

[0046] In this embodiment, a water inlet 12 is provided at the bottom of the cooling pool 1. The water inlet 12 is vertically arranged at the end of the flow guide mechanism.

[0047] The outlet of the shaping mechanism is located at the center of the beginning of the flow guiding mechanism. That is to say, the shaped hot melt adhesive is gathered in the middle of the flow guiding mechanism, so that these hot melt adhesive blocks 15 are dispersed to both sides. A water inlet 12 is arranged below the outlet of the shaping mechanism. When the coolant enters the cooling pool 1 through the water inlet 12, the water flows through the water inlet 12 to diffuse around, thereby causing some hot melt adhesive to be dispersed on both sides of the flow guiding mechanism.

[0048] In this embodiment, the guide conveyor belt 2 and the pressure plate conveyor belt 3 are both provided with a tensioning roller 13 to tighten the guide conveyor belt 2 and the pressure plate conveyor belt 3 against each other.

[0049] In this embodiment, the flow guide mechanism is tilted from bottom to top. The flow guide mechanism is tilted from bottom to top so that the hot melt adhesive is first cooled in the deep water. And gradually moves to the shallow water area. Since the cooling is mostly carried out in the shallow water area, the temperature in the deep water area is lower than that in the shallow water area. That is to say, the hot melt adhesive block 15 is first cooled in the deep water area with lower temperature, and gradually moves to the shallow water area with higher temperature, and finally achieves a good cooling effect.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
