Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0030] Reference Figure 1 As shown, the embodiment of the present application provides a mechanism for operating a plunger, comprising:

[0031] A feeding trough 1 having a working surface 11;

[0032] A gear box 2 is installed near the working surface. A plurality of plunger rods 3 are connected to the side of the gear box 2 facing the working surface. The plurality of plunger rods 3 extend toward the working surface, and the plurality of plunger rods 3 pass through the feeding trough 1.

[0033] An operating rod 4 connected to the gear box 2, with a hand wheel 5 mounted on the end of the operating rod 4 away from the gear box 2;

[0034] The working surface 11 has a first distance along the width direction of the feeding trough 1 , and the length of the operating rod 4 is greater than the first distance.

[0035] According to the above arrangement, those skilled in the art can arrange a gear box 2 , a plurality of plunger rods 3 and an operating rod 4 to control the movement of the plunger rods 3 outside the feeding trough 1 .

[0036] Specifically, those skilled in the art can set a working surface 11 on the feeding trough 1 and set a gear box near the working surface 11. Figure 1 A plurality of plunger rods 3 are installed on one side of the gear box 2 facing the working surface 11. One end of the plurality of plunger rods away from the gear box 2 can extend toward the direction of the working surface 11, and the plurality of plunger rods 3 extend into the feeding trough 1.

[0037] Those skilled in the art may also connect an operating lever 4 to the gearbox 2, wherein the operating lever 4 can control the gearbox 2, which in turn can control the multiple plunger rods 3. A handwheel 5 is mounted on the end of the operating lever 4 away from the gearbox 2. In other words, those skilled in the art can use the handwheel 5 to rotate the operating lever 4, which in turn drives the gearbox 2 to operate, and the operation of the gearbox 2 can cause the plunger rods 3 to move. Preferably, the gearbox 2 is configured as a right-angle reversing gearbox, which can further stabilize the aforementioned process.

[0038] It will be appreciated that the molten resin is stored in the feed tank 1 and can be discharged by opening the feed tank 1. Specifically, an outlet is provided in the feed tank 1 for discharging the liquid resin, and a plunger rod 3 is provided to fit within the outlet. This structure allows the outlet to be opened and closed by movement of the plunger rod 3, thereby enabling the discharge of the liquid resin.

[0039] With the above structure, a person skilled in the art can use the handwheel 5 to drive the operating lever 4 to rotate. The rotation of the operating lever 4 drives the gearbox 2 to work. The operation of the gearbox 2 can move the plunger rod 3. The movement of the plunger rod 3 opens and closes the outlet. Preferably, a handle is installed on the side of the handwheel 5 away from the operating lever.

[0040] In summary, those skilled in the art can operate the plunger outside the feeding trough 1 through the gear box 2, the operating rod 4 and the plunger rod 3, thereby avoiding the need for workers to lean into the feeding trough 1 for operation, thereby improving the safety of the equipment during use.

[0041] In the above embodiment, the gear box 2 is arranged near the working surface 11. Preferably, the gear box 2 is fixedly connected to a support frame 6 on the side facing the working surface. The support frame 6 has a connecting plate 61 and a support plate 62, wherein the connecting plate 61 is fixedly connected to the gear box 2, and the side of the connecting plate 61 away from the gear box 2 is fixedly connected to the support plate 62, and the support plate 62 extends toward the direction of the feeding trough 1 and is fixedly connected to the feeding trough 1.

[0042] With the above structure, those skilled in the art can configure the support frame 6 to secure the relative position of the gearbox 2. The support frame 6 is composed of a connecting plate 61 and a support plate 62. Specifically, the ends of the connecting plate 61 are fixed to the gearbox 2 and the support plate 62, respectively. The end of the support plate 62, away from the connecting plate 61, is fixedly connected to the feeding trough 1.

[0043] according to Figure 1 The support plate 62 is positioned on the side of the gearbox 2 facing the working surface 11, thereby separating the gearbox 2 from the feeding trough 1. It will be appreciated that those skilled in the art may set a predetermined height between the gearbox 2 and the feeding trough 1, thereby providing gearboxes 2 with different predetermined heights depending on the internal structure of the feeding trough. Gearboxes 2 with different predetermined heights can achieve stable control of the plunger rod 3 according to actual conditions, thereby ensuring stable opening and closing of the feeding trough 1.

[0044] In the above arrangement, preferably, the plane of the connecting plate 61 is perpendicular to the plane of the support plate 62. That is, the support plate 62 and the connecting plate 61 are connected vertically. This further optimizes the installation space for the support frame 6 and avoids interference with the support frame 6 when the operator operates the operating lever 4.

[0045] More preferably, the connecting plate 61 is parallel to the working surface 11. In the above arrangement, the support plate 62 is vertically connected to the connecting plate 61, and the side of the connecting plate 61 away from the gear box 2 is fixedly connected to the support plate 62. The support plate 62 extends toward the direction of the feeding trough 1 and is fixedly connected to the feeding trough 1.

[0046] With the above structure, those skilled in the art can arrange the connecting plate 61 to be parallel to the working surface 11, thereby ensuring that the plunger rod 3 remains stable during movement. Specifically, during the movement of the plunger rod 3, the connecting plate 61 is parallel to the working surface 11, thereby preventing the plunger rod 3 from colliding with the connecting plate 61 and the working surface 11.

[0047] Preferably, an observation slit is provided on one side of the feeding trough 1 adjacent to the working surface for observing the movement of the plunger rod, so that the staff can record and control the situation in the feeding trough 1 during operation.

[0048] Those skilled in the art may also arrange multiple gear boxes 2 fixed by support frames 6 on the working surface 11 , thereby enabling simultaneous operation of multiple outlets of the feeding trough 1 .

[0049] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.

[0050] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
