Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to an electric dispensing machine. Background Technology

[0002] Currently, most glue dispensing methods on the market are either pneumatic or manual. Pneumatic methods, due to the long air pressure release process, can lead to significant glue overflow from the tube, affecting usability and increasing costs. Manual methods, due to prolonged manual squeezing, are difficult to control torque, often resulting in too much or too little glue being dispensed. Therefore, an electric dispensing machine is provided. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing an electric dispensing machine to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric dispensing machine, comprising a dispensing machine handle, a glue infeed drive device, and a control box. The glue infeed drive device is installed at one end of the dispensing machine handle, and the control box is installed on the dispensing machine handle. A glue outlet is provided at the other end of the dispensing machine handle. A charging port and a lead screw port are provided on the end face of the glue infeed drive device. A motor is installed inside the glue infeed drive device, and a reduction gearbox is installed on one side of the motor. A first gear is connected to the main shaft of the reduction gearbox, and the first gear meshes with a second gear. A threaded through hole is provided at the center of the second gear, and a lead screw is threadedly connected to the threaded through hole. The threaded through hole communicates with the glue outlet inside the dispensing machine handle. A storage battery is also installed inside the glue infeed drive device.

[0005] As a preferred technical solution of this utility model, the center position of the lead screw insertion hole and the center position of the second gear are on a straight line, a push block for pushing the glue stick is installed at one end of the lead screw, and the glue stick is provided inside the handle of the dispensing machine.

[0006] As a preferred embodiment of this utility model, the second gear is fixed to the glue infeed drive device by a bearing, the threaded through hole on the second gear is used to insert the glue stick, and a hot melt metal block is installed on the inner side wall of the glue outlet of the glue dispensing machine handle.

[0007] In a preferred embodiment of this invention, the battery is electrically connected to the control button on the control box, and the control button is electrically connected to the motor.

[0008] As a preferred embodiment of this utility model, the control box is fixed to the handle of the dispensing machine by bolts.

[0009] As a preferred technical solution of this utility model, the glue feeding drive device is equipped with a display screen for displaying the glue feeding mode, speed and temperature. The display screen is electrically connected to the temperature sensor on the hot melt metal block through the controller, and the display screen is electrically connected to the frequency converter connected to the gearbox through the controller.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this dispensing machine, through the setting of a program, can be applied to all glue tube dispensing products on the market because the program is set with multiple dispensing methods such as point dispensing, continuous dispensing, automatic dispensing, dispensing return dispensing, continuous dispensing return dispensing, and self-return dispensing.

[0011] This dispensing machine uses a motor that rotates in both directions to drive a gear. The gear has a threaded hole on its inner wall, and a standard lead screw is screwed into the gear. First, the glue tube is inserted into the gear, and then the lead screw is rotated into the gear. After the gearbox starts, the lead screw will automatically move forward. Because the moving speed is very slow, the torque is very large. When the predetermined time is reached, the gearbox will reverse under the control of the program to release the pressure in the glue tube and prevent glue overflow. The amount of glue can be controlled. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] Example: Please refer to Figure 1-5 This utility model provides a technical solution: an electric dispensing machine, including a dispensing machine handle 1, a glue infeed drive device 2, and a control box 3. The glue infeed drive device 2 is installed at one end of the dispensing machine handle 1, and the control box 3 is installed on the dispensing machine handle 1. The other end of the dispensing machine handle 1 is provided with a glue outlet 4. The end face of the glue infeed drive device 2 is provided with a charging socket 7 and a lead screw socket 205. A motor 201 is installed inside the glue infeed drive device 2. A reduction gearbox 202 is installed on one side of the motor 201. A first gear 203 is connected to the main shaft of the reduction gearbox 202. The first gear 203 is meshed with a second gear 204. A threaded through hole is provided at the center of the second gear 204. A lead screw 206 is threadedly connected to the threaded through hole. The threaded through hole communicates with the glue outlet 4 inside the dispensing machine handle 1. A storage battery 207 is also installed inside the glue infeed drive device 2.

[0020] The center of the lead screw insertion hole 205 is on the same straight line as the center of the second gear 204. One end of the lead screw 206 is equipped with a push block to move the glue stick. The glue stick is located inside the dispensing machine handle 1. The lead screw 206 moves forward, thereby causing the push block to push the glue stick forward, thus realizing automatic glue dispensing.

[0021] The second gear 204 is fixed to the glue feeding drive device 2 by a bearing. The threaded through hole on the second gear 204 is used to insert the glue stick. A hot melt metal block is installed on the inner wall of the glue outlet 4 of the glue dispensing machine handle 1. The hot melt metal block is used to heat melt the glue stick, thereby melting the glue stick and dispensing glue.

[0022] The battery 207 is electrically connected to the control button 5 on the control box 3. The control button 5 is electrically connected to the motor 201. The motor 201 is powered on and operated by controlling the control button 5.

[0023] The control box 3 is fixed to the dispensing machine handle 1 by bolts.

[0024] The glue feeding drive unit 2 is equipped with a display screen 8, which is used to display the glue mode, speed and temperature. The display screen 8 is electrically connected to the temperature sensor on the hot melt metal block through the controller. The display screen 8 is also electrically connected to the frequency converter connected to the gearbox 202 through the controller, so as to directly view which mode is used and the glue dispensing temperature.

[0025] Working Principle: This electric dispensing machine operates by pressing control button 5, which powers the motor 201 via battery 207. The motor 201 then operates according to a set mode. Three control buttons 5 are provided, each corresponding to a different working mode. Common modes include point dispensing, continuous dispensing, and automatic dispensing. When motor 201 operates, it drives gearbox 202, which in turn drives first gear 203, which in turn drives second gear 204. The second gear 204 has a threaded through-hole at its center. The glue stick is inside the dispensing machine handle 1. The screw 206 moves forward, causing a pusher block at one end of the screw 206 to move the glue stick. Because the movement is slow and the torque is high, the motor reverses at the predetermined time to release the pressure inside the glue tube, preventing glue overflow. The amount of glue dispensed can be controlled.

[0026] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
