Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, specifically to an extruder structure, dispensing equipment, and heated dispensing equipment. Background Technology

[0002] A glue extruder is a glue applicator that squeezes glue out of a glue tube. It is widely used in daily life and manufacturing, such as in mobile phone repair and sealing and bonding of electronic products.

[0003] Chinese patent CN215278341U discloses a manual glue gun, including a glue gun handle and a glue container connected to each other, and a push rod that passes through the axis of the glue container and the inside of the glue gun handle and extends outside the glue gun handle. This manual glue gun achieves quantitative glue dispensing by moving the push rod in and out. However, this manual glue gun has poor flexibility in fine glue dispensing, especially in applications requiring fine glue dispensing, such as mobile phone repair. If a large force is required to squeeze out the glue, it reduces the flexibility and precision of the glue dispensing operation, making it inconvenient. At the same time, when the glue dispensing stops, the push rod locks, and the pressure inside the glue container cannot be released, causing the glue to overflow from the opening, resulting in glue waste and affecting the glue dispensing operation.

[0004] Based on this, the present invention designs an extruder structure, a dispensing device, and a heated dispensing device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an extruder structure, a dispensing device, and a heated dispensing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An extruder structure includes a glue cartridge mounting slot, a pressure rod, and a push rod;

[0008] The upper end of the rubber tube mounting slot is fixedly equipped with columns and limiting brackets on both sides; a push rod is slidably connected in the middle of the rubber tube mounting slot to push the piston inside the rubber tube.

[0009] One end of the pressure rod is hinged to the column via a fixed shaft, and a handle is fixedly installed on the other end of the pressure rod.

[0010] A spring is provided between the rubber tube mounting slot and the limiting bracket. The upper and lower ends of the spring are fixedly connected to the rubber tube mounting slot and the lever, respectively. A round hole is provided at one end of the lever, and the push rod passes through the limiting bracket, the round hole on the lever, and the spring.

[0011] The end of the pressure rod near the fixed shaft is fixedly installed with a horizontal shaft for pressing down the other end of the lever;

[0012] The limiting bracket is equipped with a stroke adjustment structure for adjusting the push rod stroke.

[0013] Furthermore, the stroke adjustment structure adopts an adjusting nut, the upper end of the limiting bracket is threadedly connected to the adjusting nut through a threaded sleeve, and the lower end of the adjusting nut abuts against the lever.

[0014] Furthermore, the diameter of the circular hole is slightly larger than the diameter of the push rod.

[0015] Furthermore, a pressure plate is fixedly installed at the lower end of the push rod.

[0016] Furthermore, the grip bar is equipped with an anti-slip structure to increase friction.

[0017] This utility model also discloses a dispensing device, including the above-mentioned extruder structure, a glue cylinder, and a piston that is slidably connected to the inner wall of the glue cylinder. The glue cylinder is filled with glue liquid; the pressure plate at the lower end of the push rod abuts against the piston.

[0018] This utility model also discloses a heated dispensing device, including the above-mentioned extruder structure and heating chamber, wherein the heating chamber is engaged with the glue cylinder mounting position by a locking block at its upper end.

[0019] This utility model has the following technical effects:

[0020] In this invention, by gripping the lever, the push rod slides downward, creating a thrust on the piston inside the glue tube, squeezing the glue out of the glue tube opening. When the lever is released, the spring drives the paddle to return to its original position, and the paddle drives the pressure rod to return to its original position via the horizontal axis. During the upward return of the paddle, the push rod also moves upward to its original position until the paddle touches the bottom of the adjusting nut, restoring the horizontal state. The pressure on the push rod is also released, thus avoiding the problem of glue continuously overflowing from the glue tube outlet due to the inability to release the internal pressure of the glue tube. This not only makes it convenient for users to operate but also reduces glue waste.

[0021] By rotating the adjusting nut, the height of the lower end of the adjusting nut can be changed, thereby adjusting the position of the paddle in its natural state. The lower the position of the paddle, the smaller the downward stroke of the push rod when the lever is gripped, and vice versa, thus achieving the adjustment of the stroke range of the push rod.

[0022] The grip bar is equipped with anti-slip protrusions to increase friction. When the user grips the bar, the power arm of the pressure bar is several times that of the resistance arm, which effectively reduces the force required for dispensing glue, making it easier for the user to perform dispensing operations. This enhances the dexterity of the hand and allows the user to perform more precise dispensing operations. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1

[0033] Please refer to the instruction manual appendix. Figure 1 A glue extruder structure includes a glue cartridge mounting slot 10, a pressure rod 13, and a push rod 21;

[0034] The upper end of the rubber tube mounting slot 10 is fixedly installed with columns 11 and limiting brackets 12 on both sides; the middle of the rubber tube mounting slot 10 is slidably connected with a push rod 21, which is used to push the piston 24 inside the rubber tube 23.

[0035] One end of the pressure rod 13 is hinged to the column 11 via a fixed shaft 15, and the other end of the pressure rod 13 is fixedly installed with a handle 20.

[0036] A spring 18 is provided between the rubber tube mounting slot 10 and the limiting bracket 12. The upper and lower ends of the spring 18 are fixedly connected to the rubber tube mounting slot 10 and the lever 16, respectively. A round hole 17 is provided at one end of the lever 16, and the push rod 21 passes through the limiting bracket 12, the round hole 17 on the lever 16, and the spring 18.

[0037] The pressure rod 13 is fixedly mounted with a horizontal shaft 14 for pressing down the other end of the paddle 16 at one end near the fixed shaft 15;

[0038] The diameter of the circular hole 17 is slightly larger than the diameter of the push rod 21, so that there is a gap between the circular hole 17 and the push rod 21.

[0039] The upper end of the limiting bracket 12 is threadedly connected to the adjusting nut 19 via a threaded sleeve, and the lower end of the adjusting nut 19 abuts against the lever 16.

[0040] The lower end of the push rod 21 is fixedly equipped with a pressure plate 22 for pushing the piston 24 inside the rubber cylinder 23;

[0041] In this utility model, the glue tube 23 is inserted into the glue tube mounting slot 10 by the locking block at its upper end, thereby connecting the glue tube 23 and the glue tube mounting slot 10.

[0042] When the grip lever 20 is gripped, the grip lever 20 drives the horizontal shaft 14 to press down the paddle 16, causing the paddle 16 to tilt. The tilted paddle 16 clamps the push rod 21 through the round hole 17, causing the push rod 21 to slide downward. This, in turn, creates a thrust on the piston 24 inside the glue tube 23 through the pressure plate 22, squeezing the glue liquid 25 out of the glue tube opening.

[0043] When the lever 20 is released, the spring 18 drives the paddle 16 to return to its original position. The paddle 16 then drives the pressure rod 13 to return to its original position via the horizontal shaft 14. During the process of the paddle 16 moving upward to return to its original position, the push rod 21 also moves upward to return to its original position until the paddle 16 touches the bottom of the adjusting nut 19 and returns to a horizontal state. The pressure on the push rod 21 is also released, thus avoiding the problem of glue 25 continuously overflowing from the glue outlet of the glue tube 23 due to the inability to release the internal pressure of the glue tube 23. This not only makes it convenient for users to operate, but also reduces the waste of glue 25.

[0044] By rotating the adjusting nut 19, the height of the lower end of the adjusting nut 19 can be changed, thereby adjusting the position of the paddle 16 in its natural state. The lower the position of the paddle 16, the smaller the downward stroke of the push rod 21 when the grip lever 20 is gripped, and vice versa, thus achieving the adjustment of the push rod stroke amplitude.

[0045] The grip 20 is equipped with an anti-slip structure that increases friction. The anti-slip structure can be made of silicone. When the user grips the grip 20, the power arm of the pressure rod 13 is several times the resistance arm, which effectively reduces the force required for dispensing glue, making it easier for the user to perform dispensing operations. This enhances the dexterity of the hand and allows the user to perform more precise dispensing operations.

[0047] like Figure 1 and 2 As shown, a dispensing device includes the above-described extruder structure, a glue cylinder 23, and a piston 24 slidably connected to the inner wall of the glue cylinder 23. The glue cylinder 23 is filled with glue liquid 25. The piston 24 is used to abut against the pressure plate 22 at the lower end of the push rod 21.

[0048] Example 3

[0049] like Figure 3 As shown, a heating dispensing device includes the above-mentioned extruder structure and a heating chamber 26. The heating chamber 26 is connected to the glue tube mounting position 10 by a locking block at its upper end, and the glue tube 23 is located inside the heating chamber 26 and is continuously heated by the heating chamber 26.

[0050] The structure of the heating chamber 26 can adopt a handheld PUR hot melt adhesive heating and dispensing device disclosed in utility model patent CN217392841U.
