Description

Technical Field

[0001] This application relates to the field of fluid spraying equipment technology, and in particular to a quick-release adhesive supply and heating mechanism. Background Technology

[0002] Some existing spraying equipment uses pneumatic dispensing. To improve the flowability of the adhesive, a heated dispensing system is usually also provided. The heated dispensing system mainly includes a heating tank. The glue bottle is inserted into the heating tank from top to bottom and heated to the set temperature. Then, air pressure is applied to dispensing. When the glue in the bottle is exhausted, the bottle is removed from the heating tank and replaced with a new one. Since some glue remains at the bottle opening, it is easy for this glue to drip into the heating tank and along the entire removal path, causing the equipment to become dirty and requiring timely cleaning. Because the heating tank is quite deep, it is not easy to observe from top to bottom, and the internal temperature is high, which can easily burn the operator, making cleaning work quite difficult. Summary of the Invention

[0003] To address the technical problem of difficult cleaning in existing heated glue supply systems, this invention provides a quick-release glue supply heating mechanism.

[0004] The technical solution provided in this application is as follows: A quick-release glue dispensing heating mechanism includes a first half-shell heating assembly, a second half-shell heating assembly, and a sealing cap assembly. The first half-shell heating assembly and the second half-shell heating assembly are hinged together by side hinges to form a heating cavity. The heating cavity is used to accommodate a glue bottle. The sealing cap assembly is disposed on the top of the first half-shell heating assembly or the second half-shell heating assembly. The inner end of the sealing cap assembly is used to seal the bottom of the glue bottle, and the outer end is used to connect to an external pneumatic dispensing device.

[0005] By adopting the above technical solution, this application splits the original one-piece heating tank into a first half-shell heating assembly and a second half-shell heating assembly. The first half-shell heating assembly and the second half-shell heating assembly are hinged together by side hinges, forming a heating chamber that can heat the glue bottle placed inside. When replacing the glue bottle, simply open the second half-shell heating assembly to easily remove the glue bottle from the side, which is very convenient. At the same time, it is also more conducive to cleaning. First, the glue bottle can be removed and placed horizontally more quickly, which can reduce the amount of glue dripping. Second, it is easier to clean and wipe. After opening, both the first half-shell heating assembly and the second half-shell heating assembly are in a semi-open state on the side, allowing the human eye to directly observe the position and amount of glue dripping. It is also easier for the human hand or tools to reach in and clean and wipe, quickly completing the cleaning work. After replacing the glue bottle, the sealing cap assembly is fixed to the top of the first half-shell heating assembly or the second half-shell heating assembly to seal the bottom of the glue bottle, ensuring good airtightness when supplying glue.

[0006] Preferably, both the first half-shell heating assembly and the second half-shell heating assembly include a shell, a semi-circular heating element, a heating tube, a thermocouple, and an electrical connection plug. The heating element is disposed inside the shell and has a heat insulation gap between it and the shell. The heating tube and the thermocouple are both disposed on the heating element. The electrical connection plug is disposed on the shell and is electrically connected to both the heating tube and the thermocouple.

[0007] By adopting the above technical solution, the heating element is semi-circular, which is adapted to the shape of the glue bottle, and the glue bottle is heated in three dimensions, resulting in more uniform heating. By setting up thermocouples, the heating temperature can be precisely controlled.

[0008] Preferably, the outer casing includes a heat-insulating side plate and a heat-insulating bottom plate. The heat-insulating side plate is disposed on the heat-insulating bottom plate, and the heat-insulating bottom plate is also provided with a glue bottle connector for fixing the head of the glue bottle and allowing the head of the glue bottle to pass through the heat-insulating bottom plate.

[0009] By adopting the above technical solution, the stability of the glue bottle in the heating chamber is ensured, and the glue bottle can be smoothly dispensed from the head.

[0010] Preferably, a heat insulation material is also provided in the heat insulation gap between the heating element and the heat insulation side plate.

[0011] By adopting the above technical solution, heat transfer from the heating element to the outer shell is reduced, thereby lowering the risk of workers being burned by excessively high outer shell temperatures.

[0012] Preferably, the sealing cap assembly includes a bayonet cap, a compression spring, a sealing element, a limiting element, a venting connector, a heat insulation connector, and a quick-connect connector. The bayonet cap has a gas connection cavity inside. The venting connector is fixedly disposed at the vent hole at the top of the bayonet cap and communicates with the gas connection cavity. The quick-connect connector communicates with the venting connector through the heat insulation connector. The sealing element is elastically and floatingly disposed inside the bayonet cap. The compression spring is disposed inside the gas connection cavity and located between the sealing element and the inner wall of the bayonet cap. The sealing element has a sealing ring on its side and a sealing gasket on its outer end face. The limiting element is used to fix the sealing gasket on the sealing element. The sealing ring is used to seal the inner wall of the gas connection cavity inside the bayonet cap. The sealing gasket is used to achieve a planar seal on the bottle mouth. The outer shells of the first half-shell heating assembly and the second half-shell heating assembly have bayonets, and the bayonet cap snaps into the bayonet.

[0013] By adopting the above technical solution, the sealing element has a floating effect due to the compression spring. After the sealing element has a certain floating compression amount, it can better adapt to the height tolerance of the glue bottle and always press against the bottle mouth. It has the function of self-sealing the glue bottle and ensures good airtightness when supplying glue.

[0014] Preferably, the bayonet cover is provided with a heat insulation sleeve.

[0015] By adopting the above technical solution, the high temperature is isolated, and the staff can operate with bare hands without wearing heat-resistant gloves.

[0016] Preferably, the first half-shell heating assembly and the second half-shell heating assembly are further provided with a door lock assembly. The door lock assembly includes a knob and a fixing block. The knob and the fixing block are respectively disposed on the heat insulation side plates of the first half-shell heating assembly and the second half-shell heating assembly. The knob head is provided with a screw, and the fixing block is provided with a threaded hole. The screw is screwed into the threaded hole to lock the knob and the fixing block. The knob is provided with a heat insulation sleeve.

[0017] By adopting the above technical solution, the locking and unlocking between the first half-shell heating component and the second half-shell heating component can be quickly realized, preventing the second half-shell heating component from being accidentally opened during operation.

[0018] Preferably, it further includes a backplate mounting mechanism, which includes a mounting backplate, two mounting side plates, and a reinforcing block. The two mounting side plates are respectively mounted on both sides of the mounting backplate. The reinforcing block is used to strengthen the connection between the mounting backplate and the mounting side plates. The front ends of the two mounting side plates are provided with semi-open mounting grooves. The first half-shell heating assembly is provided with corresponding limiting blocks. The limiting blocks are inserted into the mounting grooves. The two sides of the first half-shell heating assembly are also respectively fixed to the two mounting side plates by bolts. The bolts are provided with heat insulation sleeves.

[0019] By adopting the above technical solution, various specifications of first half-shell heating components and second half-shell heating components can be installed on the back plate mounting mechanism to adapt to plastic bottles of different shapes and sizes. Moreover, it is easy to disassemble and assemble and is replaceable.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. When changing the glue bottle, simply open the heating element of the second half of the shell to easily remove the glue bottle from the side, which is very convenient; at the same time, it is also more conducive to cleaning work, and can quickly complete the cleaning work.

[0022] 2. The heating element is semi-circular, which matches the shape of the glue bottle, and provides three-dimensional heating of the glue bottle, resulting in more uniform heating. By setting up a thermocouple, the heating temperature can be precisely controlled.

[0023] 3. The backplate mounting mechanism can be equipped with various specifications of first half-shell heating components and second half-shell heating components to adapt to plastic bottles of different shapes and sizes. It is also easy to install and remove and is replaceable. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0038] Reference Figure 1 and Figure 2 This application discloses a quick-release glue dispensing heating mechanism, including a first half-shell heating assembly 1, a second half-shell heating assembly 2, and a sealing cap assembly 3. The first half-shell heating assembly 1 and the second half-shell heating assembly 2 are hinged together by a side hinge 4 to form a heating chamber, which is used to accommodate a glue bottle. The sealing cap assembly 3 is disposed on the top of the first half-shell heating assembly 1 or the second half-shell heating assembly 2. The inner end of the sealing cap assembly 3 is used to seal the bottom of the glue bottle, and the outer end is used to connect to an external pneumatic dispensing device.

[0039] Reference Figure 1 and Figure 12 The quick-release adhesive heating mechanism also includes a back plate mounting mechanism 6. The back plate mounting mechanism 6 includes a mounting back plate 61, two mounting side plates 62, and a reinforcing block 63. The two mounting side plates 62 are respectively mounted on both sides of the mounting back plate 61. The reinforcing block 63 is used to strengthen the connection between the mounting back plate 61 and the mounting side plates 62. The front ends of the two mounting side plates 62 are provided with semi-open mounting grooves 621. The first half-shell heating assembly 1 is provided with a corresponding limiting block 18. The limiting block 18 is inserted into the mounting groove 621. The two sides of the first half-shell heating assembly 1 are also fixed to the two mounting side plates 62 by bolts 64.

[0040] The backplate mounting mechanism 6 can accommodate various specifications of the first half-shell heating assembly 1 and the second half-shell heating assembly 2 to fit different shapes and sizes of plastic bottles. It is easy to install and remove; after disconnecting the external control cable and the gas pipe, the first half-shell heating assembly 1 and the second half-shell heating assembly 2 can be completely disassembled. The mounting backplate 61 and the two mounting side plates 62 form a single-sided open frame-like enclosure structure. Through the positioning structure of the limiting block 18 and the mounting groove 621, the first half-shell heating assembly 1 can be quickly pre-positioned onto the backplate mounting mechanism 6. Then, when locking the bolt 64, it is no longer necessary to support the first half-shell heating assembly 1 and the second half-shell heating assembly 2, making installation and removal easier and providing replaceability.

[0041] Reference Figure 1 The first half-shell heating assembly 1 and the second half-shell heating assembly 2 are also equipped with a door lock assembly 5. The door lock assembly 5 includes a knob 51 and a fixing block 52. The knob 51 and the fixing block 52 are respectively disposed on the heat insulation side plates 111 of the first half-shell heating assembly 1 and the second half-shell heating assembly 2. The knob 51 has a screw 511 at its head end, and the fixing block 52 has a threaded hole 521. The screw 511 is screwed into the threaded hole 521 to lock the knob 51 and the fixing block 52. This allows for quick locking and unlocking between the first half-shell heating assembly 1 and the second half-shell heating assembly 2, preventing the second half-shell heating assembly 2 from accidentally opening during operation.

[0042] Reference Figure 6 and Figure 7 The first half-shell heating assembly 1 and the second half-shell heating assembly 2 both include a shell 11, a semi-circular heating element 12, a heating tube 13, a thermocouple 14, and an electrical connector 15. The heating element 12 is disposed inside the shell 11 and has a heat insulation gap 16 between it and the shell 11, typically a few millimeters. The heating tube 13 and the thermocouple 14 are both disposed on the heating element 12. The electrical connector 15 is disposed on the shell 11 and is electrically connected to both the heating tube 13 and the thermocouple 14. Specifically, the shell 11 includes a heat-insulating side plate 111 and a heat-insulating bottom plate 112. The heat-insulating side plate 111 is disposed on the heat-insulating bottom plate 112. The heat-insulating bottom plate 112 also has a glue bottle connector 17 for fixing the head of the glue bottle and allowing the head of the glue bottle to pass through the heat-insulating bottom plate 112, ensuring the stability of the glue bottle in the heating chamber and ensuring that the glue bottle can smoothly dispense glue from the head. After the heating element 13 and thermocouple 14 are electrically connected to the electrical connector 15, they are then connected to the external control cable. The heat generated by the heating element 13 can be quickly conducted to the heating element 12. The heating element 12 is made of a material with high thermal conductivity, such as aluminum, so the temperature is relatively uniform. In addition, the heating element 12 is semi-circular, which is compatible with the shape of the plastic bottle, so that the plastic bottle is heated in three dimensions and the heating is more uniform. By setting the thermocouple 14, the heating temperature can be precisely controlled.

[0043] A heat insulation gap 16 is provided between the heating element 12 and the outer shell 11 to reduce heat transfer from the heating element 12 to the outer shell 11. If necessary, heat insulation material or reflective sheet can also be provided in the heat insulation gap 16 to reduce heat transfer to the outside. The outer shell 11 is preferably made of a material with good heat insulation effect to reduce the risk of workers being burned by excessively high temperature of the outer shell 11.

[0044] Reference Figures 8 to 11 The sealing cap assembly 3 includes a bayonet cap 31, a compression spring 32, a sealing element 33, a limiting element 34, a venting connector 35, a heat insulation connector 36, and a quick-connect connector 37. The bayonet cap 31 has a gas connection cavity 311. The venting connector 35 is fixedly disposed at the vent hole at the top of the bayonet cap 31 and communicates with the gas connection cavity 311. The quick-connect connector 37 communicates with the venting connector 35 through the heat insulation connector 36. The sealing element 33 is elastically and floatingly disposed within the bayonet cap 31, and the compression spring 32 is disposed within the gas connection cavity 311. The sealing element 33 is located between the inner wall of the sealing element 33 and the bayonet cover 31. The sealing element 33 has a sealing ring 331 on its side and a sealing gasket 332 on its outer end face. The limiting element 34 is used to fix the sealing gasket 332 on the sealing element 33. The sealing ring 331 is used to seal the inner wall of the gas connection cavity 311 inside the bayonet cover 31. The sealing gasket 332 is used to seal the surface of the bottle mouth. The outer shell 11 of the first half-shell heating assembly 1 and the second half-shell heating assembly 2 is provided with a bayonet 113. The bayonet cover 31 is snapped into the bayonet 113.

[0045] Because of the compression spring 32, the sealing element 33 has a floating effect. After the sealing element 33 has a certain amount of floating compression, it can better adapt to the height tolerance of the glue bottle and always keep it tightly against the bottle opening. It has the function of self-sealing the glue bottle and ensures good airtightness when supplying glue. The heat insulation joint 36 provides intermittent heat insulation to prevent the high-temperature venting connector 35 from transferring heat to the quick-connect joint 37, thereby preventing the air tube connected to the quick-connect joint 37 from softening and maintaining sufficient airtightness. The quick-connect joint 37 and the air tube can rotate 360° and be quickly inserted and removed, improving operability.

[0046] The process of installing the glue bottle in this application is as follows: Rotate knob 51 to unlock door lock assembly 5. At this time, pull knob 51 to open the second half-shell heating assembly 2. Then remove the sealing cap assembly 3 and insert it into the glue bottle, so that the glue bottle's dispensing nozzle is inserted into the glue bottle connector 17. Then reinstall the sealing cap assembly 3. The glue bottle pushes the sealing element 33 upward, and the compression spring 32 inside the bayonet cover 31 is compressed. The sealing gasket 332 on the sealing element 33 abuts against the bottle mouth to form a planar seal. The sealing ring 331 seals the inner wall of the air connection cavity 311 inside the bayonet cover 31, ensuring no air leakage during pneumatic glue supply. Then rotate the sealing cap assembly 3 to make the bayonet cover 31 snap into the bayonet 113 of the first half-shell heating assembly 1. Then close the first half-shell heating assembly 1 and rotate knob 51 to lock door lock assembly 5, completing the installation of the glue bottle. The process of removing the glue bottle in this application is exactly the opposite and will not be described in detail.

[0047] In this application, the bayonet cover 31 is provided with a heat insulation sleeve, the knob 51 is provided with a heat insulation sleeve, and the bolt 64 is also provided with a heat insulation sleeve, which can isolate high temperature and allow workers to operate it by hand without wearing heat insulation gloves.

[0048] The implementation principle of this application is as follows: This application splits the original one-piece heating tank into a first half-shell heating component 1 and a second half-shell heating component 2. The first half-shell heating component 1 and the second half-shell heating component 2 are hinged together by a side hinge 4, forming a heating chamber that can heat the glue bottle placed inside. When replacing the glue bottle, simply open the second half-shell heating component 2 to easily remove the glue bottle from the side, which is very convenient. At the same time, it is also more conducive to cleaning. First, the glue bottle can be removed and placed horizontally more quickly, which can reduce the amount of glue dripping. Second, it is easier to clean and wipe. After opening, both the first half-shell heating component 1 and the second half-shell heating component 2 are in a semi-open state on the side, and the position and amount of glue dripping can be directly observed by the human eye. It is also easier for the human hand or tools to reach in and clean and wipe, and the cleaning work can be completed quickly. After replacing the glue bottle, the sealing cap component 3 is fixed to the top of the first half-shell heating component 1 or the second half-shell heating component 2 to seal the bottom of the glue bottle and ensure good airtightness when supplying glue.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
