Description

Technical Field

[0001] This utility model relates to the field of fluid equipment technology, specifically a novel hot glue pump. Background Technology

[0002] A pressure plate pump is a general-purpose colloid conveying device that operates on the principle of a pressure plate. Its main working principle is to compress the liquid using the pressure plate, thereby creating flow. When the pressure plate inside the pump body rises, the volume of the compression chamber within the pump cavity decreases, and the liquid is discharged; when the pressure plate descends, the volume of the compression chamber within the pump cavity increases, and the liquid is drawn in. In this way, the pressure plate pump can compress liquid and deliver it to the required location.

[0003] However, due to the increasingly widespread application of colloids in modern industry, there is a need to maintain a certain temperature range when applying colloids. Therefore, there is an urgent need for a warm colloid pump that can add heating and temperature regulation control functions to the existing pressure plate pump. Utility Model Content

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] Example: Figure 1 As shown, a novel hot glue pump includes a pressure plate pump body 1, a lower cylinder heating assembly 2, a heatable pressure plate 3, a control cabinet 4, and a liquid level sensor 105. The lower cylinder heating assembly 2 is installed on the outside of the plunger pump 104 at the lower end of the pressure plate pump body 1. The heatable pressure plate 3 is connected to the plunger pump 104. The control cabinet 4 is locked on a cylinder bracket on one side of the pressure plate pump body 1. The liquid level sensor 105 is locked on a crossbeam at the upper end of the pressure plate pump body 1. The pressure plate pump body 1 includes a pneumatic control unit 101, a lifting cylinder 102, and a pneumatic motor head 103. The pneumatic control unit 101 located on one side of the equipment is used to control the lifting and lowering of the lifting cylinder 102 and the compression of the plunger pump 104. The pneumatic motor head 103 located at the top of the equipment, the plunger pump 104 at the lower end of the pneumatic motor head 103, and the heatable pressure plate 3 are raised and lowered synchronously.

[0029] like Figure 2 As shown, the lower cylinder heating assembly 2 includes a front cover 210, a rear cover 207, an upper heating ring 202, and a lower heating ring 205. The front cover 210 and the rear cover 207 are interlocked, and the interlocking position is located on the periphery of the cylinder of the plunger pump 104. The upper heating ring 202 is connected to the upper end of the outer wall of the cylinder of the plunger pump 104 through an upper aluminum adapter 203 provided on the inner side. The lower heating ring 205 is connected to the lower end of the outer wall of the cylinder of the plunger pump 104 through a lower aluminum adapter 206 provided on the inner side. An over-temperature protector 204 is provided below the upper aluminum adapter 203 for real-time temperature monitoring. When the temperature exceeds the safety threshold, the circuit can be automatically cut off. The lower cylinder heating assembly 2 also includes a first temperature sensor 208, which is located below the upper aluminum adapter 203.

[0030] Electrical energy is transmitted to the heating wire 304 via the second cable connector 201. Current flows through the upper heating ring 202 and the lower heating ring 205, converting electrical energy into heat energy to heat the device. The upper aluminum adapter 203 and the lower aluminum adapter 206 conduct the heat generated by the upper and lower heating rings 205 to relevant components, ensuring effective heat transfer to the areas requiring heating. The first temperature sensor 208 monitors the internal temperature in real time and transmits the temperature signal to the control cabinet 4. The control cabinet 4 compares the preset temperature value with the actual monitored temperature value: if the actual temperature is lower than the set temperature, the control cabinet 4 maintains or increases the power supply to the heating rings to generate more heat; if the actual temperature is higher than the set temperature, it reduces or cuts off the power supply. The over-temperature protector 204, as a safety component, continuously monitors the temperature. Once the internal temperature exceeds its preset safe temperature value, the over-temperature protector 204 quickly triggers an action to cut off the circuit, preventing component damage or safety accidents due to excessive temperature. A grounding screw 209 is provided above the lower aluminum adapter 206 to ensure that when the device has a fault such as leakage, the current can flow into the ground through the grounding screw 209, thus ensuring the safety of the operators and equipment.

[0031] like Figure 3 As shown, the heatable pressure plate 3 includes an upper cover 302, a pressure plate body 309, a heating wire 304, an upper aluminum adapter ring 303, and a lower aluminum adapter ring 305. The upper cover 302 is installed on the upper end of the pressure plate body 309. The upper aluminum adapter ring 303 and the lower aluminum adapter ring 305 are engaged and sleeved on the upper end of the pressure plate body 309. The heating wire 304 is installed between the upper aluminum adapter ring 303 and the lower aluminum adapter ring 305. The heat generated by the heating wire 304 is transmitted through the upper aluminum adapter ring 303 and the lower aluminum adapter ring 305. The mating ring 305 conducts heat to the pressure plate body 309, ensuring that heat can be evenly transferred to the pressure plate body 309. A graphite sheet 306 is provided between the lower aluminum mating ring 305 and the pressure plate body 309. The graphite sheet 306 is a ring-shaped thin sheet to assist in the even distribution of heat. An overheat protector 308 is provided on the pressure plate body 309 to monitor the temperature of the pressure plate body 309 in real time. When the temperature rises abnormally and exceeds the safety threshold, it can quickly respond and cut off the circuit. A second temperature sensor 307 is provided on the pressure plate body 309.

[0032] Electrical energy is transmitted to the heating wire 304 via the third cable connector 301. When the heating wire 304 is energized, the electrical energy is converted into heat energy. The generated heat is conducted to the pressure plate body 309 through the upper aluminum adapter ring 303 and the lower aluminum adapter ring 305, respectively. Graphite sheets 306 help distribute the heat more evenly on the pressure plate body 309. A second temperature sensor 307 monitors the temperature of the pressure plate body 309 in real time, converting the temperature information into an electrical signal and transmitting it to the control cabinet 4. The control cabinet 4 compares the received temperature signal with the preset temperature value. If the actual temperature is lower than the set temperature, it maintains or increases the current of the heating wire 304 to generate more heat; if the actual temperature is higher than the set temperature, it reduces the current or cuts it off. An overheat protector 308, as a safety component, constantly monitors the temperature of the pressure plate body 309. Once the temperature rises abnormally and exceeds its preset safe temperature value, the overheat protector 308 immediately triggers, cutting off the circuit of the heating wire 304 to prevent damage to the equipment and workpiece or safety accidents caused by excessive temperature.

[0033] like Figure 4 As shown, the control cabinet 4 includes a housing 409, indicator lights 401, a switch button 405, a visual control module 402, a 24V power supply 403, and a circuit board module 408. The lower end of the housing 409 is fixed to the cylinder bracket by a fixing plate 406. The indicator lights 401 are installed on the top of the housing 409. The visual control module 402 and the 24V power supply 403 are installed inside the housing 409. The switch button 405 is installed on one side of the housing 409. The switch button 405 is connected to the circuit breaker converter 404 provided inside the housing 409. The circuit board module 408 is installed on the outer wall of the other side of the housing 409. A first cable connector 407 is provided on one side of the outer wall of the housing 409. A second cable connector 201 is provided on the upper end of the rear cover 207. A third cable connector 301 is provided on the upper end of the upper cover 302. The first cable connector 407, the second cable connector 201, and the third cable connector 301 are connected by provided cables.

[0034] Operators can set equipment operating parameters and other information through the visual control module 402, and turn the equipment on or off using the switch button 405. The circuit board module 408, as the control core, receives command signals from the visual control module 402 and monitors and controls the equipment's operating status. When the equipment is in different operating states, the indicator light 401 will illuminate with different colors or flashing patterns to provide feedback to the operator on the equipment's operating status, such as normal operation or fault alarm. The circuit breaker converter 404 plays a crucial role in on / off control in the circuit, connecting or disconnecting the circuit based on the control signals issued by the circuit board module 408.

[0035] In practical use, the operator raises the lifting cylinder 102 to a certain height using the pneumatic control unit 101. At this time, the pneumatic motor head 103, the lower cylinder, and the heatable pressure plate 3 rise together. Then, the glue bucket is placed under the heatable pressure plate 3, and the lifting cylinder 102 is lowered and pressed above the glue surface of the glue bucket using the pneumatic control unit 101. Then, the switch button 405 on the control cabinet 4 is turned on, and the temperature parameters are adjusted and heating begins through the visual control module 402. At this time, the upper heating ring 202 and lower heating ring 205 in the lower cylinder heating assembly 2 begin to work, and the heating wire 304 in the heatable pressure plate 3 begins to work. The temperature is transmitted to the control cabinet 4 through the first temperature sensor 208 and the second temperature sensor 307, and the temperature range is controlled in real time. After the temperature reaches the preset temperature and remains constant, the operator starts the pneumatic motor head 103 and the plunger pump 104 through the pneumatic control unit 101 to pump out the heated constant-temperature glue.
