For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figures 1 to 5 As shown, the rubber strip weighing device of the present invention is used to weigh the rubber strip 10 , and specifically includes a material dividing mechanism 20 , a weighing mechanism 30 and a transfer mechanism 40 .

[0040] See also Figure 1 and Figure 2As shown, the material distribution mechanism 20 includes a placement plate 21 and a push plate 22 movably connected to the placement plate 21. When the rubber strip 10 that has been cut into strips is placed on the upper end of the placement plate 21, the push plate 22 can push the rubber strip 10 to move. Further, the push plate 22 is arranged at the lower end of the placement plate 21. The placement plate 21 is provided with a plurality of long strip-shaped perforations 211 arranged in parallel and equidistantly. A plurality of protrusions 221 extend from the upper end of the push plate 22. The protrusions 221 are arranged corresponding to the perforations 211, and the upper ends of the protrusions 221 pass through the perforations 211. The material distribution mechanism 20 also includes a pushing cylinder 23 arranged at one end of the push plate 22. The pushing cylinder 23 drives the push plate 22 to move along the perforations 211, and the protrusions 221 push the rubber strip 10 on the placement plate 21 along the perforations 211.

[0041] See also Figure 1 and Figure 3 As shown, the weighing mechanism 30 includes a weighing frame 31 disposed at one end of the placement plate 21, and a weighing sensor 32 disposed at the lower end of the weighing frame 31. The rubber strip 10 is placed on the weighing frame 31, and the weighing sensor 32 is used to detect the weight of the rubber strip 10 placed in the weighing frame 31. Further, the weighing frame 31 includes a bottom plate 311 and stoppers 312 symmetrically distributed on both sides of the upper end surface of the bottom plate 311, and connecting beams 313 are provided between the stoppers 312, and an overhead layer is formed between the connecting beams 313 and the bottom plate 311, wherein the connecting beams 313 are arranged at intervals, and gaps are left between them, so that the transfer mechanism 40 can extend into the weighing frame 31 to clamp the rubber strip 10. In addition, an outwardly extending extension portion 314 and an overhead layer 315 are provided at the upper end of the limiting member 312 , and the extension portions 314 and overhead layers are provided on both sides. 315 are extended outwardly at the same time to expand the upper end opening of the weighing frame 31 , so as to facilitate the insertion of the rubber strip 10 .

[0042] See also Figure 1 , Figure 4 as well as Figure 5 As shown, the transfer mechanism 40 includes an X-axis driving module 41, a Y-axis driving module 42 mounted on the X-axis driving module 41, a lifting module 43 mounted on the Y-axis driving module 42, and a clamping assembly 44 mounted on the lifting module 43. The transfer mechanism 40 is used to move the rubber strip 10 from the dispensing mechanism 20 to the weighing mechanism 30. The clamping assembly 44 clamps the rubber strip 10, and the X-axis driving module 41, the Y-axis driving module 42 and the lifting module 43 respectively drive the rubber strip 10 to move along the XYZ axis direction.

[0043] Specifically, the X-axis driving module 41 includes a first driving motor 411 and a first screw 412 that are driven and connected. A connecting seat 413 is sleeved on the outer side of the first screw 412. The first driving motor 411 drives the connecting seat 413 to move linearly along the first screw 412. The Y-axis driving module 42 is fixed to the upper end of the connecting seat 413.

[0044] Specifically, the Y-axis driving module 42 includes an L-shaped connecting frame 421 mounted on the upper end of the connecting base 413, a second driving motor 422 mounted on one side of the connecting frame 421, and a second screw 423 mounted on one side of the connecting frame 421; the lifting module 43 is mounted on the outer side of the second screw 423, and the second driving motor 422 drives the lifting module 43 to move linearly along the second screw 423.

[0045] Specifically, the clamping assembly 44 includes a connecting rod 441, and two clamping modules 442 that are relatively arranged on the connecting rod 441 and have the same structure. The clamping module 442 includes a third driving motor 443, a third screw 444 that is drivingly connected to the third driving motor 443, a connecting member 445 that is arranged on the connecting rod 441 and drivingly connected to the third screw 444, and a pneumatic clamping jaw 446 fixed on the connecting member 445. The pneumatic clamping jaw 446 is used to clamp the rubber strip 10, and the third driving motor 443 drives the pneumatic clamping jaw 446 to move back and forth along the connecting rod 441 to adjust the position.

[0046] Furthermore, the clamping module 442 also includes a pushing cylinder 447 vertically arranged on one side of the pneumatic clamp 446. Since the rubber strip 10 has a certain viscosity and there is a probability of adhering to the pneumatic clamp 446, the pushing cylinder 447 pushes the rubber strip 10 downward, so that the rubber strip 10 is separated from the pneumatic clamp 446.

[0047] Furthermore, a connecting plate 448 is fixedly provided on one side of the pneumatic clamp 446, and two symmetrically distributed bearings 449 are provided on one side of the connecting plate 448. When the pneumatic clamp 446 clamps the rubber strip 10, the bearings 449 guide the rubber strip 10 to ensure that the rubber strip 10 is centered and placed in the central position of the weighing frame 31, thereby ensuring the weighing accuracy.

[0048] Compared with the prior art, the rubber strip weighing device involved in the utility model automatically weighs the rubber strip 10, ensures that the weight of the rubber strip 10 meets the shipping requirements, has high weighing efficiency, and ensures the accuracy of the rubber products formed by fluidization in the later stage; specifically, a material dividing mechanism 20, a weighing mechanism 30 and a transfer mechanism 40 are provided, wherein the pushing plate 22 in the material dividing mechanism 20 pushes the rubber strip 10 after the strip is cut, ensures that a single rubber strip 10 is weighed each time, and avoids missing measurements and multiple measurements; the weighing mechanism 30 includes a weighing frame 31 and a weighing sensor 32, the weighing frame 31 is used to place the rubber strip 10, and the weighing sensor 32 is used to detect the weight of the rubber strip 10 Weight, fast and effective; in addition, a transfer mechanism 40 is configured, which can drive the rubber strip 10 to move from the dividing mechanism 20 to the weighing mechanism 30 to automatically complete the weighing; in addition, since the rubber strip 10 has a certain viscosity, a pushing cylinder 447 is vertically arranged to be used for the detachment of the rubber strip 10, and two symmetrically distributed bearings 449 are also arranged. When the pneumatic clamp 446 clamps the rubber strip 10, the bearing 449 plays a guiding role to ensure that the rubber strip 10 is located in the central position, thereby ensuring that the rubber strip 10 can be placed in the central position of the weighing frame 31, ensuring that the force on the upper end surface of the weighing frame 31 is uniform, so as to improve the weighing accuracy of the weighing sensor 32.

[0049] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
