[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] The present application provides a material-patting mechanism. As shown in Figure 1 and Figure 2 In the present embodiment, the material-patting mechanism 10 includes a first driving unit 100, a second driving unit 200 and a material-patting rod 300. The first driving unit 100 and the second driving unit 200 are both arranged on a machine table. The first driving unit 100 can drive the material-patting rod 300 to move along a first horizontal direction, that is, the X direction as shown in Figure 1 , and it can also be said that the first driving unit 100 drives the material-patting rod 300 to move back and forth. The second driving unit 200 can drive the material-patting rod 300 to move up and down, that is, along the Z direction as shown in Figure 1 . The material-patting rod 300 is driven to move horizontally and up and down by the first driving unit 100 and the second driving unit 200, and the material-patting operation of the material-patting rod 300 is completed.

[0037] As shown in Figure 9As shown, the end of the material-patting rod 300 is provided with a material-patting head 310. When the material-patting rod 300 is pressed down, the material-patting head 310 can pat the material on the material belt into the injection mold, avoiding the material floating outside the mold to affect the injection effect. Since the material on the material belt is arranged in a continuous row, as shown in the enlarged portion in FIG. 4A, the material-patting head 310 is provided with a plurality of protrusions 311 arranged in a row, and each protrusion 311 corresponds to one material to be patted. In this way, the material-patting head 310 can pat multiple materials at the same time, improving the material-patting efficiency. Figure 9 As shown in the enlarged portion in FIG. 4A, the material-patting head 310 is provided with a plurality of protrusions 311 arranged in a row, and each protrusion 311 corresponds to one material to be patted. In this way, the material-patting head 310 can pat multiple materials at the same time, improving the material-patting efficiency.

[0038] Specifically, as shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 1 Figure 2 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300.

[0039] As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 7 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 5 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300.

[0040] As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 7 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 5 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300. Figure 1 As shown in FIGS. 1, 2, 3 and 4, the material-patting device 1 comprises a first driving unit 100, a second driving unit 200, and a material-patting rod 300.​Figure 4 As shown, the eccentric block 220 is located at the highest point, and the material-beating rod 300 rises to the highest point.

[0041] like Figure 4 As shown, the connection between the raking rod 300 and the lifting plate 230 is a sliding connection, and the sliding direction is along the first horizontal direction (X direction). In this way, the lifting plate 230 drives the raking rod 300 to rise and fall without affecting the movement of the raking rod 300 along the first horizontal direction (X direction).

[0042] In the slapping mechanism 10 of the present embodiment, the second drive unit 200 for driving the slapping rod 300 to rise and fall is an eccentric drive mechanism comprising a second motor 210, an eccentric weight 220, and a lifting plate 230. The second motor 210 of the second drive unit 200 drives the eccentric weight 220 to rotate, which in turn drives the lifting plate 230 to rise and fall, and the lifting plate 230 drives the slapping rod 300 to rise and fall to perform the slapping operation. The use of an eccentric drive mechanism as a lifting drive mechanism allows the slapping rod 300 to be raised and lowered at any position, requiring only the corresponding parameters to be set, making debugging easy and eliminating the need for frequent debugging. In contrast, in the prior art, the slapping rod 300 is driven by a cylinder, resulting in a fixed position and inconvenient debugging. Each debugging operation requires simultaneous adjustment of the position of the limit block to limit the position, which is extremely inconvenient.

[0043] In one embodiment, if Figure 2 As shown, the first drive unit 100 includes a first motor 110, a screw-nut structure 120, and a first slider 130. The nut of the screw-nut structure 120 is the driving end of the first drive unit 100. The screw of the screw-nut structure 120 is connected to the rotor 211 of the first motor 110, and the nut of the screw-nut structure 120 is connected to the first slider 130. The first slider 130 is provided with a first slide groove 131 extending in the vertical direction. The shaving rod 300 is provided with a guide block 320, which is slidably disposed in the first slide groove 131. The rotation of the first motor 110 drives the screw of the screw-nut structure 120 to rotate, and the screw drives the nut of the screw-nut structure 120 to move along the first horizontal direction (X direction). The nut drives the first slider 130 to move synchronously, and the first slider 130 drives the shaving rod 300 to move along the first horizontal direction (X direction). At the same time, because the swivel rod 300 is slidably connected to the first slide groove 131 on the first slider 130, the lifting and lowering of the swivel rod 300 is not affected. The use of the screw nut structure 120 to drive the swivel rod 300 back and forth can make the movement of the swivel rod 300 more stable. The movement distance can be adjusted by setting parameters, making operation convenient.

[0044] like Figure 2As shown, both the eccentric block 220 and the guide block 320 may adopt a rolling structure, which can reduce the friction between them and the sliding mating surface. The eccentric block 220 and the guide block 320 may adopt a cam bearing follower, for example.

[0045] like Figure 7 As shown, the lifting plate 230 includes a vertical plate 231 and a horizontal plate 232 that are perpendicular to each other, as well as a second slider 233. A strip-shaped hole 2311 is provided on the vertical plate 231, and the vertical plate 231 is connected to the eccentric weight 220. The second slider 233 is provided on the horizontal plate 232, and a second chute 2331 is provided on the second slider 233, in which the shaving rod 300 is slidably provided. It is understood that the second chute 2331 extends along the first horizontal direction (X direction), thereby allowing the shaving rod 300 to slide along the first horizontal direction (X direction). Designing the lifting plate 230 to include a structure of the vertical plate 231 and the horizontal plate 232 facilitates the connection of the eccentric weight 220 and the installation of the second slider 233.

[0046] like Figure 2 As shown, the material shooting mechanism 10 also includes a mounting frame 400. Figure 8 As shown, the mounting frame 400 includes a column 410 and a mounting plate 420 disposed on the top of the column 410. Figure 3 As shown, the second motor 210 is hung under the mounting plate 420 of the mounting frame 400 through the end plate 212. Figure 5 As shown, the vertical plate 231 of the lifting plate 230 of the second drive unit 200 passes from above the mounting plate 420 of the mounting frame 400 to below the mounting plate 420 and is connected to the second motor 210 located below the mounting plate 420. The installation of the mounting frame 400 facilitates the installation and fixation of the second drive unit 200 and ensures the stability of the lifting plate 230 of the second drive unit 200.

[0047] In order to further improve the stability of the lifting plate 230, Figure 5 As shown, a vertical downward guide column 2321 is provided on the horizontal plate 232 of the lifting plate 230. A linear bearing 421 is provided on the mounting plate 420 of the mounting frame 400. Figure 5 As shown, the guide column 2321 is inserted into the linear bearing 421 to guide the lifting and lowering of the lifting plate 230.

[0048] like Figure 8 As shown, the mounting frame 400 further includes a first bottom plate 430 and a second bottom plate 440. The first bottom plate 430 is arranged on the machine platform, the second bottom plate 440 is arranged on the first bottom plate 430, and the column 410 and the mounting plate 420 are both arranged on the second bottom plate 440. Figure 6 and Figure 8As shown, the fine adjustment assembly 450 is arranged between the second base plate 440 and the first base plate 430, and is capable of adjusting the installation position of the second base plate 440 on the first base plate 430, i.e. the position of the second base plate 440 on the machine table, so as to adjust the position of the mounting plate 420 and the second driving unit 200 on the machine table.

[0049] In an embodiment, as shown in Figure 8 The fine adjustment assembly 450 includes a first adjustment block 451 and a second adjustment block 452 arranged oppositely, and an adjustment nut 453. The first adjustment block 451 is arranged on the first base plate 430, the second adjustment block 452 is arranged on the second base plate 440, and the adjustment nut 453 is arranged on the first adjustment block 451, with the end of the adjustment nut 453 being threadedly connected with the second adjustment block 452. By screwing the adjustment nut 453, the second base plate 440 can be pulled to move, so as to adjust the position of the second base plate 440. The principle of pulling the second base plate 440 to move by the adjustment nut 453 is similar to that of the screw nut structure, and the adjustment nut 453 is equivalent to the screw rod of the screw nut structure, and the second adjustment block 452 on the second base plate 440 is equivalent to the nut of the screw nut structure. After adjusting the position of the second base plate 440, the second base plate 440 can be fixed by locking screws. It can be understood that the adjustment nut 453 is only arranged on the first adjustment block 451, and the surface of the adjustment nut 453 matched with the first adjustment block 451 is a smooth surface without threads.

[0050] In an embodiment, as shown in Figure 8 The fine adjustment assembly 450 is used to adjust the installation position of the second base plate 440 on the machine table along the second horizontal direction (Y direction), which can also be understood as adjusting the position of the second base plate 440 left and right. Therefore, as shown in Figure 8 The first adjustment block 451 and the second adjustment block 452 are arranged oppositely along the second horizontal direction (Y direction). The adjustment nut 453 is arranged along the second horizontal direction (Y direction).

[0051] The fine adjustment assembly 450 can adjust the installation position of the second base plate 440 along the second horizontal direction (Y direction), so as to adjust the position of the second driving unit 200 along the second horizontal direction (Y direction), i.e. adjust the position of the second driving unit 200 left and right. Further, in order to adjust the installation position of the second driving unit 200 along the first horizontal direction (X direction), i.e. adjust the position of the second driving unit 200 front and back, as shown in Figure 8As shown, the first bottom plate 430 is provided with an adjusting hole 431 extending along the first horizontal direction. The first bottom plate 430 can be fixed by passing a screw through the first adjusting hole 431 and locking it on the machine table. When adjusting, loosen the screw, move the first bottom plate 430 along the first horizontal direction (X direction) forward and backward, lock the screw again to fix the first bottom plate 430 after adjusting the position. The adjusting hole 431 can be used to adjust the installation position of the first bottom plate 430 along the first horizontal direction (X direction), and the installation position of the second driving unit 200 along the first horizontal direction (X direction) on the first bottom plate 430 can also be adjusted.

[0052] As shown, Figure 6 The mounting frame 400 is provided with a photoelectric sensor 500. The photoelectric sensor 500 is used to detect the closing height of the external mold to avoid the external mold from damaging the material tapping mechanism 10. When the mold is close to the photoelectric sensor 500 and is about to press the material tapping mechanism 10, the photoelectric sensor 500 will detect the approach of the mold and issue an audible and visual alarm.

[0053] The working process of the material tapping mechanism 10 of the embodiment is as follows:

[0054] Referring to Figure 1 , the first driving unit 100 and the second driving unit 200 are both in the initial position and wait for the mold opening signal;

[0055] Referring to Figure 4 , the second driving unit 200 receives the mold opening signal, the second motor 210 rotates to drive the lifting plate 230 and the material tapping rod 300 to rise to the specified position;

[0056] After receiving the lifting signal, the first motor 110 of the first driving unit 100 rotates to drive the material tapping rod 300 to move forward along the X direction to the specified position;

[0057] After receiving the forward movement signal, the second driving unit 200 moves downward to complete the material tapping action, and then rises to the specified position;

[0058] After the material tapping action is completed, a signal is issued, and the first driving unit 100 moves backward to retract the material tapping rod 300 after receiving the signal.

[0059] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0060] The above embodiments only express the implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
