[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] like Figure 1-7 As shown, the present invention provides an automatic trimming device for bulk molding plastic products, the device comprising: a base 1, a movable platform 2 and a grinding mechanism;

[0038] The upper end of the base 1 is horizontally and reciprocally movable with a mobile platform 2, and the mobile platform 2 is provided with a clamping mechanism for fixing and clamping the workpiece, and the clamping mechanism includes: a limit plate 3, a positioning plate 4 and a pressure plate 11; wherein,

[0039] A row of limit plates 3 are fixedly and horizontally arranged at equal intervals on the upper end of the movable platform 2 along its moving direction, and the width between each two adjacent limit plates 3 is equal to the width of the workpiece; a grinding mechanism for sequentially grinding the workpieces arranged on the movable platform 2 is arranged on the base 1 on one side of the movable platform 2; a positioning plate 4 capable of moving toward the grinding mechanism is also fixedly and horizontally arranged on the upper end of the movable platform 2; a row of avoidance grooves corresponding to and matching all the limit plates 3 are evenly and spaced apart at the bottom end of the positioning plate 4; a pressure plate 11 capable of resting against the workpiece is horizontally and liftably arranged on the top of the base 1.

[0040] In the above scheme, when in use, multiple workpieces are placed in the gaps between a row of the limiting plates 3 on the mobile platform 2. Since the width between each two adjacent limiting plates 3 is equal to the width of the workpiece, the two limiting plates 3 can limit the two sides of the workpiece, and move the positioning plate 4 toward the grinding mechanism to push the row of workpieces placed on the mobile platform 2 toward the grinding mechanism, so that the openings of the row of workpieces are located at the edge of the mobile platform 2, so that the grinding mechanism can perform grinding operations on the openings of the workpieces. Subsequently, the pressing plate 11 is driven to descend in the vertical direction to abut against the top of the row of workpieces, so that the row of workpieces is clamped and fixed by the clamping mechanism to prevent the tool from shifting during the grinding process and affecting the grinding effect.

[0041] According to the above method, after a row of workpieces on the mobile platform 2 are clamped and fixed by the clamping mechanism, the mobile platform 2 is moved to drive the row of workpieces to move from one end of the base 1 to the other end thereof, so that the opening of each tool passes through the grinding mechanism, so that the grinding mechanism grinds a row of workpieces fixed on the mobile platform 2 in turn, thereby improving the grinding efficiency.

[0042] In a preferred embodiment of the present invention, the grinding mechanism comprises: a first grinding roller 5 and a second grinding roller 6; wherein,

[0043] A first grinding roller 5 and a second grinding roller 6 are arranged on the base 1 at one side of the mobile platform 2 at intervals and vertically rotatably.

[0044] In the above scheme, by driving the No. 1 grinding roller 5 and the No. 2 grinding roller 6, a row of workpieces on the mobile platform 2 can be ground multiple times, thereby improving the grinding effect.

[0045] In a preferred embodiment of the present invention, the device further comprises a driving mechanism for driving the first grinding roller 5 and the second grinding roller 6 to rotate synchronously while driving the mobile platform 2 to move in the horizontal direction, the driving mechanism comprising: a first driven gear 7, a second driven gear 8, a driving gear 9 and a rack plate 10; wherein,

[0046] A No. 1 driven gear 7 and a No. 2 driven gear 8 are coaxially fixedly arranged on the rotating shafts at the bottom ends of the No. 1 grinding roller 5 and the No. 2 grinding roller 6, respectively, and a driving gear 9 meshingly connected with the No. 1 driven gear 7 and the No. 2 driven gear 8 is horizontally and rotatably arranged above the base 1 between the No. 1 driven gear 7 and the No. 2 driven gear 8, and the side wall portion of the movable platform 2 facing the driving gear 9 is recessed inward to form a No. 1 assembly groove, and a rack plate 10 meshingly connected with the driving gear 9 is horizontally fixedly arranged in the No. 1 assembly groove.

[0047] In the above scheme, if Figure 4 As shown, the diameter of the driven gear 9 is smaller than the diameter of the driving gear 8, so that when the driving gear 9 is meshed with the rack plate 10, the rack plate 10 will not be released from the driven gear 8, thereby avoiding affecting the rotation of the driven gear 8.

[0048] The arrow indicates the rotation direction of the driving gear 9. When the driving gear 9 rotates clockwise, it can drive the two driven gears 8 meshing with it to rotate synchronously counterclockwise, so as to drive the No. 1 grinding roller 5 and the No. 2 grinding roller 6 to rotate synchronously. At the same time, the driving gear 9 drives the movable platform 2 to move from left to right by driving the rack plate 10 meshing with it, so that a row of workpieces fixed on its upper end pass through the No. 1 grinding roller 5 and the No. 2 grinding roller 6 in turn, and the row of workpieces are polished in turn by the No. 1 grinding roller 5 and the No. 2 grinding roller 6, thereby improving the polishing efficiency.

[0049] When the grinding mechanism finishes grinding a row of workpieces on the mobile platform 2, the driving gear 9 is rotated in the reverse direction, so that the rack plate 10 meshing with it is driven to drive the mobile platform 2 to move in the reverse direction to its initial position during the reverse rotation of the driving gear 9. When the mobile platform 2 moves to its initial position, the staff can place the next batch of workpieces on the mobile platform 2 in sequence, clamp a row of workpieces through the clamping mechanism, and grind the next batch of workpieces in sequence according to the above-mentioned operation method.

[0050] In a preferred embodiment of the present invention, the driving mechanism further comprises a driving motor for driving the driving gear 9 to rotate in a horizontal direction; wherein,

[0051] The interior of the base 1 is a hollow structure, and a driving motor is vertically fixed inside the base 1. The output shaft of the driving motor passes through the upper end of the base 1 and is coaxially connected to the central shaft of the driving gear 9 through a coupling.

[0052] In the above scheme, when in use, the driving motor is started to drive the driving gear 9 to rotate, such as Figure 4 As shown, the arrow indicates the rotation direction of the driving gear 9. When the driving gear 9 rotates clockwise, it can drive the two driven gears 8 meshing with it to rotate synchronously counterclockwise, so as to drive the No. 1 grinding roller 5 and the No. 2 grinding roller 6 to rotate synchronously. At the same time, the driving gear 9 drives the movable platform 2 to move from left to right by driving the rack plate 10 meshing with it, so that a row of workpieces fixed on its upper end pass through the No. 1 grinding roller 5 and the No. 2 grinding roller 6 in turn, and the row of workpieces are polished in turn by the No. 1 grinding roller 5 and the No. 2 grinding roller 6, thereby improving the polishing efficiency.

[0053] In a preferred embodiment of the present invention, at least two guide rails 13 are spaced apart and horizontally fixed on the upper end of the base 1, and the bottom end of the mobile platform 2 is spaced apart and partially recessed inward to form two slide grooves compatible with the two guide rails 13, and the mobile platform 2 is horizontally and slidably assembled on the two guide rails 13 through the two slide grooves.

[0054] In the above scheme, the two guide rails 13 and the two slide grooves at the bottom of the mobile platform 2 are used in coordination to ensure that the mobile platform 2 can move back and forth horizontally and linearly on the base 1 smoothly and reliably, so that a row of workpieces on the mobile platform 2 can pass through the grinding mechanism in turn, so that the grinding mechanism can grind a row of workpieces on the mobile platform 2 in turn, thereby improving the grinding efficiency.

[0055] In a preferred embodiment of the present invention, the device further comprises a first electric telescopic rod 14 for driving the pressing plate 11 to move up and down in the vertical direction; wherein,

[0056] A No. 1 electric telescopic rod 14 is vertically fixedly disposed on the upper end of the base 1 located at the four corners of the pressure plate 11, and the telescopic end of each No. 1 electric telescopic rod 14 is vertically disposed on the corner of the No. 1 electric telescopic rod 14 corresponding thereto.

[0057] In the above solution, when in use, the pressing plate 11 is driven to move up and down in the vertical direction by starting the first electric telescopic rod 14 .

[0058] In a preferred embodiment of the present invention, the device further comprises a second electric telescopic rod 15 for driving the positioning plate 4 to move in the horizontal direction; wherein,

[0059] At least one No. 2 electric telescopic rod 15 is horizontally fixedly disposed on the mobile platform 2 away from the grinding mechanism, and the telescopic end of the No. 2 electric telescopic rod 15 is fixed on the positioning plate 4 .

[0060] In the above scheme, the second electric telescopic rod 15 is started to drive the positioning plate 4 to move toward the workpiece on the mobile platform 2 until the positioning plate 4 abuts against the workpiece, so as to further limit the workpiece by the positioning plate 4 to prevent the workpiece from shifting during the grinding process and affecting the grinding effect.

[0061] In addition, the first electric telescopic rod 14 and the second electric telescopic rod 15 can be cylinders or servo electric cylinders.

[0062] In a preferred embodiment of the present invention, the bottom end portion of the pressure plate 11 is recessed inward to form a second assembly groove, and a row of rollers 12 capable of resting against the workpiece is horizontally and rotatably arranged in the second assembly groove.

[0063] In the above scheme, when the pressure plate 11 descends to a row of rotatable rollers 12 inside it abut against a row of workpieces, when the movable platform 2 drives the row of workpieces to move in the horizontal direction, the sliding friction between the top of the workpiece and the pressure plate 11 is converted into rolling friction, so as to reduce the damage to the workpiece caused by friction and ensure the integrity of the workpiece.

[0064] In summary, the automatic trimming device for bulk molded plastic products provided by the present invention overcomes the problem in the prior art that workers are required to hold the box by hand and use a grinder to grind the opening of the box. Such operation may cause the grinder to accidentally injure the workers during the grinding process, increase the workload of the workers, and reduce the trimming efficiency.
