Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive processing technology, and more specifically, it relates to a receiving funnel for processing fluorescent display hot melt adhesive. Background Technology

[0002] Fluorescent display hot melt adhesive is an adhesive that adds fluorescent whitening agent to the traditional hot melt adhesive. Combining the bonding performance of hot melt adhesive with the function of fluorescent tracing, it can emit visible fluorescence under the excitation of a specific light source (such as ultraviolet light), realizing the dual functions of bonding and marking.

[0003] In the preparation of fluorescent display hot melt adhesive, the reaction vessel is first heated to a certain temperature, and the pre-treated raw materials are added into the reaction vessel in the order of feeding. After heating and stirring evenly, the adhesive can be discharged when the standard for dispensing is reached. After the hot melt adhesive is discharged from the reaction vessel, it is sent to the extruder for corresponding molding through the receiving funnel.

[0004] The utility model patent with application number 202322834443.8 discloses a receiving funnel for hot melt adhesive production. The power output of a stepper motor drives a connecting rod to rotate via a rotating shaft, causing the adhesive strip to make circular motion inside the funnel body. The adhesive strip cleans the hot melt adhesive adhering to the inner wall of the funnel body, and the scraped hot melt adhesive flows into the adhesive storage tank through the bottom opening of the funnel body. This not only reduces the loss of hot melt adhesive, but also effectively prevents the hot melt adhesive from clogging the bottom opening of the funnel body, ensuring the normal use of the funnel body.

[0005] However, in the existing technology, the receiving funnel is not equipped with heating and heat preservation measures. The temperature of the hot melt adhesive will drop after entering the receiving funnel, which may cause the hot melt adhesive to become viscous and increase the difficulty of cleaning the adhesive strip. In addition, the temperature of the inner wall of the funnel is too low, and the hot melt adhesive may start to solidify before cleaning, resulting in incomplete cleaning. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a receiving funnel for processing fluorescent display hot melt adhesive.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A receiving funnel for processing fluorescent display hot melt adhesive includes a funnel body and a cleaning unit for cleaning the inner wall of the funnel. The funnel body is provided with a heating and heat preservation unit, which includes a heat preservation shell surrounding the funnel body, a heating element for heating the funnel body, and an end cap detachably connected to the heat preservation shell. The heat preservation shell and the funnel body cooperate to form a heat preservation space. The heating element is placed in the heat preservation space and installed on the funnel body. The end cap is provided with a feed pipe to facilitate the entry of hot melt adhesive into the funnel body.

[0009] A further configuration includes a heat insulation pad installed within the heat-insulating space, the heat insulation pad being mounted on the inner wall of the heat-insulating shell, and heat insulation cotton being connected to the end cap.

[0010] A further configuration includes a temperature sensor on the inner wall of the end cap, a controller electrically connected to the temperature sensor on the outer wall of the insulation housing, and the controller electrically connected to the heating element.

[0011] The cleaning unit is further configured to include a motor mounted on the end cap, a fixed rod placed inside the funnel body, and a scraper mounted on the fixed rod for cleaning the inner wall of the funnel body. The output end of the motor passes through the end cap and is connected to the fixed rod. The output end of the motor is rotatably connected to the end cap, and the scraper abuts against the inner wall of the funnel.

[0012] Further configured, the end cap includes a first mounting hole, and the insulation shell includes a second mounting hole corresponding to the first mounting hole, and the first mounting hole and the second mounting hole are bolted together.

[0013] A further configuration is provided, wherein a positioning groove is provided on the heat-insulating shell, a positioning block is fixed on the funnel body and inserted into the positioning groove, the positioning block is covered with an elastic rubber pad, and the elastic rubber pad abuts against the inner wall of the positioning groove.

[0014] A further configuration is provided, wherein a sealing ring is connected to the funnel body and abuts against the insulation shell, the sealing ring is located at the connection between the funnel body and the insulation shell, and the sealing ring corresponds to the positioning block.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows: a heating and heat preservation unit is provided on the funnel body to heat and preserve the hot melt adhesive entering the funnel body, thereby avoiding the problem that the hot melt adhesive becomes viscous due to the temperature drop after entering the funnel body, which increases the difficulty of scraper cleaning, and also avoiding the problem that the hot melt adhesive has already started to solidify before cleaning due to the low temperature of the inner wall of the funnel, resulting in incomplete cleaning.

[0021] Reference Figures 1 to 4 The embodiments of this utility model will be further described below.

[0022] A receiving funnel for processing fluorescent display hot melt adhesive includes a funnel body 1 and a cleaning unit 100 for cleaning the inner wall of the funnel. The funnel body 1 is provided with a heating and heat preservation unit 200, which includes a heat preservation shell 2 surrounding the funnel body 1, a heating element 3 for heating the funnel body 1, and an end cap 4 detachably connected to the heat preservation shell 2. The heat preservation shell 2 and the funnel body 1 cooperate to form a heat preservation space 5. The heating element 3 is placed in the heat preservation space 5 and installed on the funnel body 1. The end cap 4 is provided with a feed pipe 6 to facilitate the entry of hot melt adhesive into the funnel body 1. A temperature sensor 9 is provided on the inner wall of the end cap 4. A controller 10 electrically connected to the temperature sensor 9 is provided on the outer wall of the heat preservation shell 2. The controller 10 is electrically connected to the heating element 3 so that the heat generated by the heating element 3 is transferred to the funnel body 1 through the funnel body 1 to heat and preserve the hot melt adhesive entering the funnel body 1, avoiding the problem of the hot melt adhesive solidifying and being difficult to clean due to the temperature drop, and the problem of easily clogging the bottom opening of the funnel body 1.

[0023] The heat insulation space 5 is equipped with a heat insulation pad 7, which is installed on the inner wall of the heat insulation shell 2 to reduce heat loss in the heat insulation space 5. The end cap 4 is connected with heat insulation cotton 8, and the heat insulation pad 7 is installed on the inner wall of the heat insulation shell 2 to reduce heat loss in the funnel body 1 and improve the heat insulation effect.

[0024] The cleaning unit 100 includes a motor 11 mounted on the end cap 4, a fixing rod 12 placed inside the funnel body 1, and a scraper 13 mounted on the fixing rod 12 for cleaning the inner wall of the funnel body 1. The output end of the motor 11 passes through the end cap 4 and is connected to the fixing rod 12. The output end of the motor 11 is rotatably connected to the end cap 4 through a bearing. The scraper 13 abuts against the inner wall of the funnel so that the motor 11 can drive the scraper 13 to rotate through the fixing rod 12 to clean the hot melt adhesive on the inner wall of the funnel body 1, thereby preventing residual hot melt adhesive from solidifying at the bottom of the funnel body 1 and clogging the bottom of the funnel body 1.

[0025] Working principle: Hot melt adhesive enters the funnel body 1 through the feed pipe 6 on the end cap 4. The temperature sensor 9 on the inner wall of the end cap 4 monitors the temperature inside the funnel body 1 in real time. The temperature sensor 9 transmits the monitored temperature data to the controller 10. The controller 10 automatically controls the working state of the heating element 3 according to the preset temperature range. The heating element 3 is installed in the heat preservation space 5. When the temperature sensor 9 detects that the temperature inside the funnel body 1 is lower than the preset value, the controller 10 controls the heating element 3 to heat the funnel body 1, so that the temperature inside the funnel body 1 remains stable.

[0026] The insulating shell 2 and the funnel body 1 work together to form an insulating space 5. The heat insulation pad 7 is installed on the inner wall of the insulating shell 2 to further reduce heat loss and ensure that the temperature inside the funnel body 1 is kept within a suitable range. The heat insulation cotton 8 on the end cap 4 also helps to reduce heat loss from the end cap 4 and improve the heat insulation effect. By heating the heat insulation unit 200, the temperature inside the funnel body 1 is maintained, preventing the hot melt adhesive from becoming viscous due to the temperature drop, thereby reducing the difficulty of cleaning. At the same time, it prevents the temperature of the inner wall of the funnel from being too low, causing the hot melt adhesive to start to solidify before cleaning, ensuring that the cleaning process can proceed smoothly and improving the cleaning effect.

[0027] When cleaning the inner wall of the funnel body 1, the motor 11 drives the fixed rod 12 to rotate, causing the scraper 13 to move in a circular motion inside the funnel body 1. The scraper 13, in conjunction with the inner wall of the funnel body 1, moves along the inner wall to scrape off the hot melt adhesive, thus cleaning the inner wall of the funnel body 1. Because the temperature inside the funnel body 1 is effectively controlled, the hot melt adhesive does not over-solidify during the cleaning process. The scraper 13 can smoothly scrape off the hot melt adhesive and allow it to flow into the adhesive storage tank through the bottom opening of the funnel body 1. Ultimately, the heating and insulation unit 200 installed on the funnel body 1 heats and insulates the hot melt adhesive entering the funnel body 1, preventing the hot melt adhesive from becoming viscous due to temperature drop after entering the funnel body 1, which would increase the cleaning difficulty for the scraper 13. It also prevents the hot melt adhesive from solidifying before cleaning due to excessively low inner wall temperature, resulting in incomplete cleaning.

[0028] A sealing ring 19 is connected to the funnel body 100 and abuts against the insulation shell 2. The sealing ring 19 is located at the connection between the funnel body 100 and the insulation shell 2. The sealing ring 19 corresponds to the positioning block 17, and the positioning block 17 passes through the sealing ring 19 and is inserted into the positioning groove to prevent the heat in the insulation space from escaping from the connection between the funnel body 100 and the insulation shell 2, thereby reducing heat loss and improving the insulation effect of the insulation space.

[0029] The end cap 4 includes a first mounting hole 14, and the insulation shell 2 includes a second mounting hole 15 corresponding to the first mounting hole 14. The first mounting hole 14 and the second mounting hole 15 are bolted together to facilitate the disassembly and connection of the end cap 4 and the insulation shell 2. This facilitates the disassembly of the end cap 4 when the unit 100 needs to be maintained and cleaned later, and also facilitates the stable installation of the insulation shell 2. The bolted connection between the end cap 4 and the insulation shell 2 ensures that the end cap 4 seals the opening of the funnel body 1, preventing hot melt adhesive leakage. At the same time, it reduces the heat loss from the connection gap between the end cap 4 and the funnel body 1.

[0030] The insulation shell 2 has a positioning groove 16, and the funnel body 1 has a positioning block 17 that is inserted into the positioning groove 16. The positioning block 17 is covered with an elastic rubber pad 18, which abuts against the inner wall of the positioning groove 16. The design of the positioning groove 16 and the positioning block 17 facilitates the quick and accurate installation between the insulation shell 2 and the funnel body 1. The elastic rubber pad 18 on the positioning block 17 abuts against the inner wall of the positioning groove 16, which enhances the connection stability between the positioning block 17 and the positioning groove 16, thereby making the installation of the insulation shell 2 more stable and facilitating normal use in the future. At the same time, it facilitates the disassembly and connection of the insulation shell 2 and the funnel body 1, making it convenient for later inspection and maintenance of the heating element 3 and improving the convenience of later maintenance.
