Description

Technical Field

[0001] The present invention relates to the technical field of heating adhesive products, and in particular to an adhesive product heating device. Background Art

[0002] As an important industrial material, glue is widely used in many fields such as automobiles, construction, and electronics. A glue gun is a tool for applying glue (or squeezing glue), and it may be used wherever glue is needed. In the use of glue, temperature is an important factor affecting the performance of glue. Too low temperature may cause insufficient fluidity of the glue, making it difficult to fully fill the mold or contact the surface of the adherend. Therefore, before using a glue gun to apply glue, the glue gun must first be heated so that the glue inside the glue gun is fully heated to achieve the required fluidity and plasticity. However, since the glue gun tip is thinner and the gun body is thicker, it is difficult to fully heat the glue gun tip during heating, which makes it easy for the glue gun tip to be blocked, affecting the application of glue. Summary of the invention

[0003] In view of this, the embodiment of the present disclosure provides a glue heating device, which can fully heat the gun head and gun body of the glue gun. The technical solution is as follows:

[0005] The heat preservation structure has a heat preservation cavity inside;

[0006] The glue gun rack is installed in the heat preservation cavity, the glue gun rack is suitable for placing the glue gun, and at least the gun body and the gun head of the glue gun are located in the heat preservation cavity;

[0007] The heater is used to heat the interior of the heat preservation cavity.

[0008] In a possible implementation, the heater is an air heater, and the air heater is used to blow hot air toward the interior of the heat preservation cavity.

[0010] In a possible implementation, the adhesive heating device further includes a first baffle and a second baffle, and the first baffle and the second baffle both have a plurality of air holes distributed at intervals;

[0011] The first baffle is installed in the air inlet channel or in the heat preservation cavity, and blocks the side of the heater facing the inside of the heat preservation cavity;

[0012] The second baffle is installed in the air inlet channel and is located on a side of the heater away from the interior of the heat preservation cavity.

[0013] In one possible implementation, the top surface of the glue gun holder is arc-shaped, and the insulation structure has a placement hole, which passes through the side wall of the insulation structure along the arc center line of the top surface. The gun head and the gun body can pass through the placement hole into the insulation cavity, so that the gun body is placed on the top surface.

[0014] In one possible implementation, the glue gun holder also has a limiting structure, and the limiting structure is located on the moving path of the gun body entering the insulation cavity, so that when the gun body enters the insulation cavity and abuts against the limiting structure, the handle of the glue gun is located outside the insulation cavity.

[0015] In a possible implementation, the glue heating device also includes a residual glue box, which is detachably installed in the heat preservation cavity. The top of the residual glue box is provided with a residual glue inlet, and when the glue gun is placed on the glue gun rack, the residual glue inlet is located directly below the glue outlet of the gun head, so that the glue flowing out of the glue outlet of the gun head can enter the residual glue box through the residual glue inlet.

[0016] In a possible implementation, the thermal insulation structure has a glue taking port, and the glue taking port runs through a side wall of the thermal insulation structure;

[0019] In a possible implementation, the adhesive heating device further includes a temperature sensor and a controller;

[0020] The temperature sensor is installed in the heat preservation cavity and is used to detect the temperature in the heat preservation cavity. The controller is connected to the heater and the temperature sensor signal.

[0021] The controller is used to receive the temperature signal detected by the temperature sensor and control the heater to turn on or off according to the temperature signal.

[0022] In the scheme shown in the present disclosure, the heater heats the inside of the insulation cavity of the insulation structure, which can increase the temperature of the air inside the insulation cavity, and the air inside the heated insulation cavity can fully contact the gun body and gun head placed on the glue gun rack.

[0036] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0037] This embodiment relates to a rubber heating device, such as Figure 1 The figure shows the overall structure of the rubber heating device.

Fig.10 Shown is a schematic diagram of the rear view structure of the rubber heating device.

[0038] refer to Figures 1 to 4 As shown, the glue heating device includes a heat preservation structure 1, a glue gun rack 2 and a heater 3.

[0039] Among them, reference Figure 1 As shown, the insulation structure 1 has an insulation cavity 11 inside. For example, the insulation structure 1 can be a box, a box, etc., and the inside of the box or box structure can serve as the insulation cavity 11. The side walls inside the insulation cavity 11 can be arranged with insulation cotton, and the insulation cavity 11 can be airtight or appropriately connected to the outside, so that when the internal temperature of the insulation cavity 11 is high, the heat is not easily lost.

[0040] Continue to refer Figure 1 and Figure 2As shown, the glue gun rack 2 is installed in the heat preservation cavity 11, and the glue gun rack 2 is suitable for placing the glue gun 4. For example, the gun body 41 of the glue gun 4 can be placed on the glue gun rack 2, and the gun head 42 of the glue gun 4 can be in a suspended state.

[0041] Among them, at least the gun body 41 and the gun head 42 of the glue gun 4 are located in the heat preservation cavity 11. Figure 2 In the embodiment, the gun body 41 and the gun head 42 of the glue gun 4 may be located in the heat preservation cavity 11, and the handle 43 of the glue gun 4 may be located outside the heat preservation cavity 11. However, it may also be that the gun body 41, the gun head 42 and the handle 43 of the glue gun 4 are all located in the heat preservation cavity 11.

[0042] Furthermore, the heater 3 is used to heat the interior of the heat preservation cavity 11 , so that the temperature of the air inside the heat preservation cavity 11 can be increased.

[0043] As can be seen from the above, the heater 3 heats the inside of the heat preservation cavity 11 of the heat preservation structure 1, which can increase the temperature of the air inside the heat preservation cavity 11, and the heated air inside the heat preservation cavity 11 can fully contact the gun body 41 and the gun head 42 placed on the glue gun stand 2. Therefore, the air inside the heat preservation cavity 11 can fully heat the glue inside the gun body 41 and the gun head 42 by heat transfer, thereby ensuring the fluidity and plasticity of the glue inside the gun body 41 and the gun head 42.

[0044] In one example, the heater 3 is a blower, which is used to blow hot air toward the inside of the heat preservation cavity 11. In this way, the blower blows hot air into the heat preservation cavity 11, so that the heated air can flow inside the entire heat preservation cavity 11, and after being heated, it can contact the gun body 41 and the gun head 42 inside the heat preservation cavity 11 in time, thereby facilitating the rapid heating of the glue inside the gun body 41 and the gun head 42.

[0045] Moreover, due to the flow of hot air, the air temperature in each place inside the heat preservation cavity 11 can be made more uniform, so that the rubber products inside the gun body 41 and the gun head 42 can be heated uniformly, avoiding the situation where a part of the rubber products in the gun body 41 and the gun head 42 has been fully heated, but another part has not been fully heated, or a part of the rubber products in the gun body 41 and the gun head 42 has just been fully heated, while the temperature of another part is too high.

[0046] In one example, reference Figure 2 and Figure 3As shown, the thermal insulation structure 1 has an air inlet channel 12, which vertically penetrates the bottom wall of the thermal insulation structure 1, and the heater is installed in the air inlet channel 12. The air inlet channel 12 and the thermal insulation structure 1 can be integrally formed, or can be two independent structural members fixedly connected together by bolts, welding, etc. The heater can be fixedly connected to the inner wall of the air inlet channel 12 by bolts, screws, etc.

[0047] In this way, the heater is installed in the air inlet channel 12 to blow hot air toward the inside of the heat preservation cavity 11, which can ensure that the heat preservation cavity 11 has a sufficient temperature and prevent the heater from overheating and affecting the heater. In addition, the air inlet channel 12 is located below the heat preservation structure 1, which is different from the air inlet channel 12 located on the side of the heat preservation structure 1, which can not only prevent the heater from occupying more space, but also prevent the heater from being hit from the side.

[0048] At the same time, the heater blows air from bottom to top, which is also conducive to the hot air flowing evenly to various areas inside the insulation cavity 11, so that the air inside the insulation cavity 11 is more uniform, further improving the uniformity of heating the glue inside the gun body 41 and the gun head 42.

[0049] In one example, reference Figure 4 As shown, the adhesive heating device further includes a first baffle 121 and a second baffle 122. The first baffle 121 and the second baffle 122 both have a plurality of air holes 123 that are spaced apart. Figure 2 and Figure 8 In the embodiment, the plurality of air holes 123 may be evenly spaced and distributed within the circular range of the first baffle plate 121 and the second baffle plate 122. However, the plurality of air holes 123 may be evenly spaced and distributed within the square range of the first baffle plate 121 and the second baffle plate 122.

[0050] Continue to refer Figure 4 As shown, the first baffle 121 is installed in the air inlet channel 12 or in the heat preservation cavity 11, and blocks the side of the heater facing the interior of the heat preservation cavity 11. Figure 4 In the embodiment, the first baffle plate 121 can be installed in the heat preservation cavity 11, but the first baffle plate 121 can also be installed in the air inlet channel 12. The first baffle plate 121 and the heat preservation cavity 11 can be fixedly connected together by bolts, welding, etc.

[0051] In this embodiment, Figure 4The first baffle 121 shown is installed in the heat preservation cavity 11 as an example. Compared with the first baffle 121 installed in the air inlet channel 12, the first baffle 121 is installed in the heat preservation cavity 11 and can have a certain distance from the air inlet channel 12. Thus, it is beneficial to increase the amount of hot air blown into the heat preservation cavity 11 by the heater.

[0052] Moreover, since the hot air can flow toward the outside of the first baffle 121 , the hot air entering the heat preservation cavity 11 can be made more uniform, which is beneficial to further improve the uniformity of heating the glue inside the gun body 41 and the gun head 42 .

[0053] Continue to refer Figure 4 As shown, the second baffle 122 is installed in the air inlet channel 12, and is located on the side of the heater away from the interior of the heat preservation cavity 11. For example, the second baffle 122 and the air inlet channel 12 can be fixedly connected together by bolts or welding.

[0054] In this way, the first baffle 121 can prevent the items in the heat preservation structure 1 from falling into the air inlet channel 12, causing damage to the heater. At the same time, the uniformity of the warm air blown into the heat preservation cavity 11 by the heater can be improved, which is beneficial to improve the uniformity of heating the rubber products in the gun body 41 and the gun head 42. The second baffle 122 can prevent the sundries outside the heat preservation structure 1 from being sucked onto the heater, causing damage to the heater.

[0055] In one example, reference Figure 5 and Figure 6 Combined with Figure 1 and Figure 2 As shown, the top surface 21 of the glue gun holder 2 is arc-shaped. The heat preservation structure 1 has a placement hole 13, which penetrates the side wall of the heat preservation structure 1 along the arc center line of the top surface 21. The gun head 42 and the gun body 41 can pass through the placement hole 13 and enter the heat preservation cavity 11, so that the gun body 41 is placed on the top surface 21. For example Figure 1 and Figure 2 As shown, the glue gun holder 2 with an arc-shaped top surface 21 can be connected to the side wall where the placement hole 13 is located at the first end, and the second end extends in the horizontal direction. The glue gun holder 2 and the side wall of the thermal insulation structure 1 can be fixedly connected together by welding, bolts, etc. Therefore, personnel can conveniently take or place the glue gun 4 through the placement hole 13.

[0056] In one example, the radius of the top surface 21 matches the radius of the placement hole 13. For example, the radius of the top surface 21 can be equal to the radius of the placement hole 13, or the radius of the top surface 21 can be slightly smaller than the radius of the placement hole 13. Thus, after the gun body 41 enters the heat preservation cavity 11, it can be directly placed on the top surface 21 without being hindered by the placement hole 13.

[0057] In one example, the number of glue gun racks 2 and the number of placement holes 13 can both be multiple, and the glue gun racks 2 and the placement holes 13 correspond one to one. The placement holes 13 penetrate the side wall of the thermal insulation structure 1 along the arc center line of the corresponding top surface 21. Figure 1 and Figure 6 In the embodiment, the number of the glue gun racks 2 and the number of the placement holes 13 can both be two, but the number of the glue gun racks 2 and the number of the placement holes 13 can also both be three, four, etc. In this way, multiple glue guns 4 can be heated at the same time, which is conducive to improving work efficiency.

[0058] In one example, reference Figure 5 As shown, the glue gun holder 2 also has a limiting structure 22, and the limiting structure 22 is located on the moving path of the gun body 41 entering the heat preservation cavity 11. Figure 2 As shown, when the gun body 41 enters the heat preservation cavity 11 and abuts against the limiting structure 22 , the handle 43 of the glue gun 4 is located outside the heat preservation cavity 11 .

[0059] For example, in Figure 5 In the embodiment, the limiting structure 22 can be a strip-shaped structure, and the two ends of the limiting structure 22 are respectively connected to the two ends of the arc of the glue gun holder 2. However, the limiting structure 22 can also be a block-shaped, arc-shaped, etc. structure located on the top surface 21, as long as it can block the movement path of the gun body 41 and hinder the movement of the gun body 41 along the arc center line of the top surface 21.

[0060] The limiting structure 22 and the gun rack 2 may be integrally formed or may be independent structural members fixedly connected together by means of clamping, welding, etc. Moreover, the distance between the limiting structure 22 and the corresponding placement hole 13 of the glue gun rack 2 matches the length of the gun body 42, so that when the gun body 41 enters the heat preservation cavity 11 and abuts against the limiting structure 22, the handle 43 of the glue gun 4 is located outside the heat preservation cavity 11, and the push switch 44 on the handle 43 does not contact the heat preservation structure 1.

[0061] Therefore, the presence of the limiting structure 22 can prevent the handle 43 of the glue gun 4 from entering the heat preservation cavity 11, causing the handle 43 to be too hot and difficult to take out. At the same time, it can also prevent the push switch 44 of the glue gun 4 from hitting the heat preservation structure 1, causing the glue to accidentally flow out of the glue outlet of the gun head 42, causing waste.

[0062] In one example, since the glue in the glue gun 4 will maintain fluidity after being heated, the glue in the glue gun 4 may flow out from the glue outlet of the gun head 42. Figure 2 As shown, the adhesive heating device further includes a residual adhesive box 5, which is detachably mounted in the heat preservation cavity 11. For example, the residual adhesive box 5 can be placed in the heat preservation cavity 11 to facilitate the removal of the residual adhesive box 5.

[0063] refer to Figure 7 As shown, the top of the residual glue box 5 has a residual glue inlet 51. Figure 2 As shown, when the glue gun 4 is placed on the glue gun stand 2, the residual glue inlet 51 is located directly below the glue outlet of the gun head 42. Therefore, the glue flowing out of the glue outlet of the gun head 42 can enter the residual glue box 5 through the residual glue inlet 51. Therefore, the glue entering the residual glue box 5 through the residual glue inlet 51 can be collected, which is convenient for subsequent cleaning or reuse.

[0064] In one example, if Figure 7 As shown, the top of the residual glue box 5 is a second opening, so that the second opening becomes the residual glue inlet 51 of the residual glue box 5. This is helpful to prevent the glue flowing out of the glue outlet of the gun head 42 from failing to enter the residual glue inlet 51. At the same time, it is also convenient for personnel to pour out the glue entering the residual glue box 5.

[0065] In one example, reference Figure 5 As shown, the glue gun rack 2 may also have a glue box rack 23, which is located on the side of the glue gun rack 2 away from the corresponding placement hole 13, and the residual glue box 5 is detachably mounted on the glue box rack 23. For example, the residual glue box 5 can be placed on the glue box rack 23. The glue box rack 23 and the glue gun rack 2 may be integrally formed, or may be independent structural members, which are fixedly connected together by bolts, welding, etc.

[0066] In one example, reference Figure 4 As shown, the thermal insulation structure 1 has a glue outlet 14 , and the glue outlet 14 passes through the side wall of the thermal insulation structure 1 .

[0067] Continue to refer Figure 4 As shown, the rubber heating device further includes a first rubber storage rack 6, which is installed inside the heat preservation cavity 11. For example, the first rubber storage rack 6 can be fixedly connected to the side wall of the heat preservation structure 1 by bolts, welding, etc.

[0068] And, if Figure 4 As shown, the first glue storage rack 6 is tilted, and the first end of the first glue storage rack 6 is lower than the second end of the first glue storage rack 6 , and the first end of the first glue storage rack 6 extends to the glue taking port 14 .

[0069] In this way, the prepared glue can be placed on the first glue storage rack 6 in advance. On the one hand, the glue can be preheated. On the other hand, when the glue gun 4 needs to be replenished with glue, the preheated glue can be directly taken out from the glue outlet 14 without having to walk back and forth to replenish the glue.

[0070] Furthermore, since the first glue storage rack 6 is tilted, after the glue product closest to the glue dispensing port 14 is taken out, the other glue products can move to a position close to the glue dispensing port 14 due to gravity, thereby facilitating subsequent taking of glue products from the glue dispensing port 14 .

[0071] In one example, the glue dispensing port 14 may be equipped with a glue dispensing door 141. For example, the first end of the glue dispensing door 141 may be hinged on one side of the glue dispensing port 14, and the second end may be connected to the second side of the glue dispensing port 14 by a buckle. In this way, the locking and unlocking of the glue dispensing door 141 and the glue dispensing port 14 may be achieved by the buckle, and in the unlocked state, the glue dispensing port 14 may be opened or closed by rotating the glue dispensing door 141. Thus, the glue products on the first glue storage rack 6 may be taken out by opening the glue dispensing door 141, and after the glue products are taken out, the glue dispensing port 14 may be closed by the glue dispensing door 141 to prevent the temperature inside the heat preservation cavity 11 from being lost from the glue dispensing port 14.

[0072] In one example, reference Figure 1 As shown, the heat preservation structure 1 includes a shell 101 and an upper cover 102. The top of the shell 101 is a first opening, and the upper cover 102 is arranged on the first opening, so that the shell 101 and the upper cover 102 together form a heat preservation cavity 11. Fig.10 As shown, one end of the upper cover 102 can be hinged to the side wall of one side of the first opening through a hinge 1021, so that a person can open or close the first opening by rotating the upper cover 102 around the hinge 1021.

[0073] Thus, by opening the upper cover 102, on the one hand, the residual glue box 5 can be conveniently taken out or installed from the first opening of the shell 101, and on the other hand, the unheated glue product can be placed at the highest position of the first glue storage rack 6 from the first opening of the shell 101. Therefore, when the glue product is taken out from the glue taking port 14, the taken glue product can always be fully heated.

[0074] In one example, continue to refer to Fig.10 Combined with Fig. 9 As shown, the outer side of the side wall connecting the housing 101 and the upper cover 102 is also provided with a stopper 1022. When the upper cover 102 is rotated from the first open state and the rotation angle exceeds 90°, the stopper 1022 blocks the lower side of the upper cover 102, so that the upper cover 102 remains stable. In this way, the hinge 1021 can be assisted to support the upper cover 102, and the hinge 1021 can be prevented from being damaged too quickly.

[0075] In one example, the upper cover 102 may have a handle 1023 on one side away from the hinge 1021 , and the handle 1023 and the upper cover 102 may be fixedly connected together by welding, bolts, etc. In this way, the upper cover 102 may be conveniently opened or closed by the handle 1023 .

[0076] In one example, there may be multiple first glue storage racks 6, and the multiple first glue storage racks 6 are distributed up and down. Figure 4In the embodiment, the number of the first glue storage racks 6 can be two, but the number of the first glue storage racks 6 can also be three, four, etc. Thus, the capacity of the prepared glue products can be increased.

[0077] In one example, continue to refer to Figure 4 As shown, along the inclination direction of the first glue storage rack 6, the length of the first glue storage rack 6 at the lower side is greater than the length of the first glue storage rack 6 at the upper side. Therefore, it is convenient for personnel to place the unheated glue product at the highest position of the first glue storage rack 6 at the lower side through the first opening of the housing 101, and avoid the first glue storage rack 6 at the upper side from causing obstruction to the first glue storage rack 6 at the lower side.

[0078] In one example, reference Figure 1 As shown, the glue heating device may further include a second glue storage rack 9, which may include four support legs 91 and a glue storage structure 92. Figure 1 As shown, the top of the supporting leg 91 can be fixedly connected to the bottom of the thermal insulation structure 1 , and the glue storage structure 92 is fixedly connected to the four supporting legs 91 .

[0079] Therefore, on the one hand, the height of the insulation structure 1 can be increased to facilitate personnel to take and place the glue gun 4. On the other hand, more glue products can be placed on the glue storage structure 92, which can avoid personnel walking back and forth when placing glue products into the insulation cavity 11, thereby reducing efficiency.

[0080] In one example, reference Figure 1 Combined with Figure 3 As shown, the projection of the glue storage structure 92 on the horizontal plane does not overlap with the projection of the air inlet channel 12 on the horizontal plane, thereby preventing the glue placed on the glue storage structure 92 from affecting the air intake at the air inlet channel 12 .

[0081] In one example, the second glue storage rack 9 may further include a partition plate 93, the bottom of which may be fixedly connected to the glue structure 92, and the top of which may extend upward. For example, the bottom of the partition plate 9 may be fixedly connected to the glue storage structure 92 by bolts, welding, etc., and the projection of the partition plate 9 on the horizontal plane is located between the glue storage structure 92 and the air inlet channel 12. Thus, the partition plate 9 may be used to block the glue products on the glue storage structure 92, so as to prevent the glue products on the glue storage structure 92 from falling to the lower side of the air inlet channel 12 and affecting the air intake at the air inlet channel 12.

[0082] In one example, reference Figure 2 As shown, the rubber heating device further includes a temperature sensor 7 and a controller 8. The temperature sensor 7 is installed in the heat preservation cavity 11 and is used to detect the temperature in the heat preservation cavity 11. The controller 8 is connected to the heater 3 and the temperature sensor 7 by signals.

[0083] The controller 8 is used to receive the temperature signal detected by the temperature sensor 7 and control the heater 3 to turn on or off according to the temperature signal.

[0084] For example, when the value of the temperature signal detected by the temperature sensor 7 is lower than 25°, the controller 8 can control the heater to turn on and heat the heat preservation cavity 11. When the value of the temperature signal detected by the temperature sensor 7 is higher than 50°, the controller 8 can control the heater to turn off and stop heating the heat preservation cavity 11.

[0085] In this way, it can be ensured that the temperature in the heat preservation cavity 11 is always maintained near the set value, providing stable temperature conditions for the glue coating operation and avoiding the influence of temperature fluctuations on the performance and coating effect of the glue product.

[0086] In one example, reference Figure 2 As shown, the temperature sensor 7 can be installed at the bottom corner of the heat preservation cavity 11. In this way, it is beneficial to measure the overall temperature inside the heat preservation cavity 11 more accurately.

[0087] In the disclosed embodiment, the heater 3 heats the inside of the heat preservation cavity 11 of the heat preservation structure 1, which can increase the temperature of the air inside the heat preservation cavity 11, and the heated air inside the heat preservation cavity 11 can fully contact the gun body 41 and the gun head 42 placed on the glue gun holder 2. Therefore, the air inside the heat preservation cavity 11 can fully heat the glue inside the gun body 41 and the gun head 42 by heat transfer, thereby ensuring the fluidity and plasticity of the glue inside the gun body 41 and the gun head 42.
