Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a edge pressing device for rubber processing. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is highly elastic at room temperature and can deform significantly under minimal external force, returning to its original shape upon removal. Rubber is a completely amorphous polymer. When processing sheet-like rubber, a blanking device is often used.

[0003] In the prior art, edge-holding devices generally use a pressing plate that moves along both sides of a rubber sheet to adjust its position before moving up and down to hold the edges together. When the sides of the rubber sheet are relatively long, the pressing plate needs to be moved along both sides of the sheet multiple times to adjust its position before moving up and down again to complete the edge-holding process. This results in a significant waste of time and low edge-holding efficiency. A rubber processing edge-holding device is needed to address the aforementioned issues. Utility Model Content

The utility model has a reasonable structure, high edge pressing efficiency, low labor intensity and good use effect.

[0005] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions: a rubber processing edge pressing device, comprising:

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, the utility model provides a technical solution: a pressure edge device for rubber processing, comprising:

[0026] A U-shaped plate 1, a pair of L-shaped positioning plates 3 for placing rubber are symmetrically arranged on the top of the U-shaped plate 1, a pair of L-shaped positioning plates 3 are each provided with a longitudinal electric cylinder 4 on the top, a pair of longitudinal electric cylinders 4 are each provided with a pressing electric push rod 5 on the moving block, a pair of pressing electric push rods 5 are each provided with an L-shaped mounting plate 6 on the telescopic shaft, a pair of L-shaped mounting plates 6 are each provided with a first motor 8 on the side wall, and a pair of first motors 8 are each provided with a pressing wheel 7 for pressing the rubber edge at the corner of the L-shaped positioning plate 3 on the output shaft. This design drives the L-shaped mounting plate 6 to move in the vertical direction by pressing the electric push rod 5. The vertical movement of the L-shaped mounting plate 6 drives the pressure wheel 7 on the first motor 8 to move in the vertical direction, thereby adjusting the distance between the pressure wheel 7 and the rubber; the longitudinal electric cylinder 4 drives the lifting electric push rod 91 to move longitudinally, and the longitudinal movement of the lifting electric push rod 91 drives the L-shaped mounting plate 6 to move longitudinally. The longitudinal movement of the L-shaped mounting plate 6 drives the pressure wheel 7 on the first motor 8 to move longitudinally, thereby realizing simultaneous edge pressing operation on both sides of the rubber, without the need for the pressure wheel 7 to move up and down repeatedly, saving time and thus improving edge pressing efficiency.

[0027] Reference Figure 1 and Figure 2 , a driving assembly 2 is provided on the U-shaped plate 1 for driving a pair of L-shaped positioning plates 3 to move toward or away from each other;

[0028] The driving assembly 2 includes a guide limit slot 23 symmetrically provided on the top of the U-shaped plate 1. A pair of L-shaped positioning plates 3 are provided with a guide limit block 24 inserted into the guide limit slot 23 at the bottom. A screw rod 22 is provided inside the guide limit slot 23 and passes through the guide limit block 24. A driving motor 21 connected to the screw rod 22 is provided on the side wall of the U-shaped plate 1. This design drives the screw rod 22 to rotate by the driving motor 21 in the driving assembly 2. The rotation of the screw rod 22 drives the guide limit block 24 to move along the guide limit slot 23 under the action of the limit of the guide limit slot 23, thereby moving the pair of L-shaped positioning plates 3 toward or away from each other, thereby adjusting the size of the rubber to be pressed placed on the L-shaped positioning plates 3; wherein, the screw rod 22 is a bidirectional screw rod, and the screw rod 22 is connected to the guide limit block 24 by a thread.

[0029] Reference Figure 2 and Figure 3 , a turning assembly 10 for turning the rubber is provided on the U-shaped plate 1;

[0030] The flip assembly 10 includes a support plate 103 disposed inside the U-shaped plate 1. An ejection electric push rod 104 is disposed at the bottom of the support plate 103. A connecting plate 102 located above the support plate 103 is disposed on the telescopic shaft of the ejection electric push rod 104. A second motor 101 is disposed on the top of the connecting plate 102. A turntable 105 embedded in the top of the U-shaped plate 1 is disposed on the output shaft of the second motor 101. This design drives the connecting plate 102 to move upward through the operation of the ejection electric push rod 104 in the flip assembly 10. The upward movement of the connecting plate 102 drives the turntable 105 on the second motor 101 to move upward and contact the rubber. The second motor 101 is then operated to drive the turntable 105 to rotate. The rotation of the turntable 105 drives the rubber to rotate and flip, so that the side of the rubber that is not pressed is placed directly below the pressure wheel 7, avoiding manual flipping, reducing labor intensity, and achieving good use effect.

[0031] Reference Figure 1 A pair of L-shaped positioning plates 3 are connected at their joints to form guide holes 31 that match the turntable 105. This design facilitates the turntable 105 to avoid interference between the turntable 105 and the L-shaped positioning plates 3 through the guide holes 31.

[0032] Reference Figure 2The top center of the U-shaped plate 1 is provided with an embedding hole 1001 that matches the turntable 105, and the turntable 105 is completely placed inside the embedding hole 1001. This design completely stores the turntable 105 through the embedding hole 1001.

[0033] Reference Figure 1 and Figure 2 , a pressing component 9 is provided on the top of the U-shaped plate 1;

[0034] The pressing assembly 9 includes a pair of fixed plates 97 symmetrically arranged on the opposite side walls of the U-shaped plate 1, and a support column 96 is provided on the top of the pair of fixed plates 97. A connecting plate 95 is provided between the tops of the pair of support columns 96, and a lifting electric push rod 91 is provided on the top of the connecting plate 95. The telescopic axis of the lifting electric push rod 91 is provided with a connecting column 93 located below the connecting plate 95, and a pressure plate 94 is provided at the bottom of the connecting column 93 and is placed directly above the turntable 105. A bearing 92 is provided at the connection between the connecting column 93 and the telescopic axis of the lifting electric push rod 91. This design drives the connecting column 93 downward by pressing the lifting electric push rod 91 in the assembly 9. The downward movement of the connecting column 93 drives the pressure plate 94 downward to contact the upper end surface of the rubber. The upper end surface of the turntable 105 contacts the lower end surface of the rubber, thereby completing the clamping of the rubber; when the second motor 101 drives the turntable 105 to rotate, the turntable 105 and the pressure plate 94 drive the clamped rubber to rotate, and the lifting electric push rod 91 is prevented from rotating under the action of the bearing 92, thereby facilitating the rotation and flipping of the rubber, thereby completing the replacement of the pressure edge.

[0035] Reference Figure 3 A relief hole 1002 is provided at the bottom of the U-shaped plate 1 for evading the housing of the second motor 101, thereby improving the rationality of the design.

[0036] Reference Figure 1-Figure 3 As an embodiment of the present utility model: when it is necessary to press the rubber, the staff drives the screw rod 22 to rotate by operating the driving motor 21 in the driving assembly 2. The rotation of the screw rod 22 drives the guide limit block 24 to move along the guide limit groove 23 under the action of the limit of the guide limit groove 23, thereby causing a pair of L-shaped positioning plates 3 to move toward or away from each other, thereby adjusting the size of the rubber to be pressed placed on the L-shaped positioning plate 3.

[0037] When the size of the rubber is adjusted, the plate-shaped rubber is placed between a pair of L-shaped positioning plates 3, and then the longitudinal electric cylinder 4 is operated to drive the lifting electric push rod 91 to move longitudinally. The longitudinal movement of the lifting electric push rod 91 drives the L-shaped mounting plate 6 to move longitudinally. The longitudinal movement of the L-shaped mounting plate 6 drives the pressure wheel 7 on the first motor 8 to move longitudinally, and adjusts the pressure wheel 7 to a suitable pressing position. Then, the pressing electric push rod 5 is operated to drive the L-shaped mounting plate 6 to move in the vertical direction. The L-shaped mounting plate 6 moves in the vertical direction, thereby driving the pressure wheel 7 on the first motor 8 to move in the vertical direction, so that the lower end surface of the pressure wheel 7 contacts the upper end surface of the rubber, completing the adjustment of the distance between the pressure wheel 7 and the rubber, and finally, the longitudinal electric cylinder 4 is operated to drive the pressure wheel 7 to move longitudinally, thereby realizing simultaneous pressing operation on both sides of the rubber. There is no need for the pressure wheel 7 to move up and down repeatedly, saving time, thereby improving the pressing efficiency.

[0038] When the edge pressing is completed, the driving motor 21 in the driving component 2 is operated to drive a pair of L-shaped positioning plates 3 to move to the side away from each other, and then the ejection electric push rod 104 in the flipping component 10 is operated to drive the upper end surface of the turntable 105 to contact the lower end surface of the rubber, and finally the lifting electric push rod 91 in the pressing component 9 is operated to drive the connecting column 93 to move downward, and the connecting column 93 moves downward to drive the pressure plate 94 to move downward and contact the upper end surface of the rubber, thereby completing the clamping of the rubber. When the second motor 101 works to drive the turntable 105 to rotate, the turntable 105 and the pressure plate 94 drive the clamped rubber to rotate, which facilitates the rotation and flipping of the rubber, completes the replacement of the edge pressing, avoids manual flipping, reduces labor intensity, and has a good use effect.

[0039] After the edge pressing is completed, the flip assembly 10 and the pressing assembly 9 respectively drive the turntable 105 and the pressure plate 94 to return to their initial positions. Similarly, the driving assembly 2 is operated to drive a pair of L-shaped positioning plates 3 to be adjusted to a suitable position to place the rubber, and the adjusted pressure wheel 7 is moved longitudinally to perform the edge pressing operation on the flipped rubber, thereby improving the practicality of the present invention.
