The positioning and cutting component 4 includes a cutting frame 41, and the cutting frame 41 has a supporting platform 42 and a first electric cylinder 43, and the first electric cylinder 43 has a pressing plate 44. The cutting frame 41 also has a second electric cylinder 45, and a cutting knife 46 is arranged on the second electric cylinder 45. It includes a double-station feeding component 5 for carrying the cut rubber material strip, which is detachably arranged on the workbench 1 and consists of a driving end and two station ends connected to the driving end; a hot pressing forming component 6 for hot pressing the rubber material strip, which is detachably arranged on the workbench 1; an energy storage trigger component 7, which is detachably installed on the hot pressing forming component 6 and can be triggered when the hot pressing forming component 6 moves down; a side pressing component 8, which is detachably installed on the workbench 1, and when the energy storage trigger component 7 is triggered once, the side pressing component 8 can be moved down to perform positive side pressing on the rubber material strip located in the station end; when the energy storage trigger component 7 is triggered a second time, it can trigger the side pressing component 8 to continue to move down to perform side side pressing on the rubber material strip in the station end; a grabbing component 9 for grabbing the rubber material strip that has completed hot pressing, which is arranged on the workbench 1.

[0022] First of all, it is necessary to further explain the overall use of the feeding component 2, the clamping and transferring component 3 and the positioning and cutting component 4. When the rubber material strip is laid, the rubber material tray is placed on the material tray 22, and the rubber material strip is pulled out and passed through multiple groups of laying shafts 23 and a group of feeding bases 24 in turn. When the clamping and transferring component 3 is used, since the clamping and transferring component 3 is located on one side of the feeding component 2, the clamping cylinder 33 is positioned to clamp the material strip head, and the rubber material strip can be clamped and pulled out by opening the transfer cylinder 32. When cutting the rubber material strip, first place the rubber material strip head above the supporting platform 42, and move downward by opening the first electric cylinder 43 so that the pressure plate 44 positions the rubber material head, and then the second electric cylinder 45 is opened to move the cutter 46 downward to complete the one-time cutting operation of the rubber material strip. This is a one-time cutting process.

[0023] Next, a more specific structure and construction is given to the double-station feeding component 5 as a whole for further explanation. The driving end of the double-station feeding component 5 includes a first linear module 51, which is arranged on the workbench 1; a rotary cylinder 52, which is arranged on the moving end of the first linear module 51; a material-bearing plate 53, which is arranged on the output end of the rotary cylinder 52; the station end of the double-station feeding component 5 includes a molding lower mold 54, and a squeezing rod 56 is slidably arranged on the side of the molding lower mold 54, and a squeezing plate 55 is connected to the tail end of the squeezing rod 56, and a squeezing spring 57 is sleeved on the squeezing rod 56; Next, the overall use principle of the double-station feeding member 5 is further explained. Initially, one of the groups of molding lower dies 54 is located below the positioning and cutting member 4. After the rubber material strip is cut once, it can fall into the molding lower die 54. Then, the rotary cylinder 52 is turned on to rotate the group of molding lower dies 54 that have completed the material loading. The first linear module 51 is turned on to send the molding lower die 54 loaded with the rubber material strip to the bottom of the positioning and cutting member 4, and the second group of molding lower dies 54 is continuously filled with material strips. Since the material strips that fall into the molding lower die 54 are in a wrinkled and uneven state, if the edge is not pressed during the actual hot pressing molding, the effect of the hot pressing molding product will be affected. In addition, it should be noted that the first linear module 51 is a known component in the prior art, so it is not described in detail in the present invention. The first linear module 51 is driven by a motor to rotate the screw rod, and the screw rod drives the ball base to move left and right, so it is not described in detail in the invention.

[0024] Next, the hot press forming component 6 is given a more specific structure and construction as a whole for further explanation. The hot press forming component 6 includes a mounting frame 61, which is arranged on the workbench 1; a mounting plate 62, which is arranged on the mounting plate 62, and a third electric cylinder 63 is arranged on the mounting plate 62; a forming upper mold 64, which is arranged on the output end of the third electric cylinder 63, and a forming template 65 is arranged on the forming upper mold 64, wherein when the forming template 65 penetrates into the forming lower mold 54, the forming upper mold 64 and the forming lower mold 54 can be in a mold-closing state; Next, the use principle of the entire hot-pressed forming component 6 is further explained. The staff turns on the third electric cylinder 63 to enable the forming upper mold 64 to drive the forming template 65 to move downward as a whole. When the forming template 65 penetrates into the forming lower mold 54, the forming upper mold 64 and the forming lower mold 54 can be in a mold-closed state to complete the hot-pressing forming operation of the rubber material strip.

[0025] Next, the energy storage trigger component 7 is given a more specific structure and construction as a whole for further explanation. The energy storage trigger component 7 includes a connecting frame 71, which is arranged on the workbench 1, and a horizontal plate 72 is arranged on the connecting frame 71; a fourth electric cylinder 73, which is arranged on the horizontal plate 72, and a displacement plate 74 is arranged on the output end of the fourth electric cylinder 73; a fifth electric cylinder 75, which is arranged on the displacement plate 74, and a connecting base plate 76 is detachably arranged on the output end of the fifth electric cylinder 75; a step block 77, which is arranged on the forming upper mold 64; an energy storage rod 78, which is slidably arranged in the connecting base plate 76, and a pressure wheel 79 is arranged at the tail end of the energy storage rod 78, and a tooth plate 792 is arranged on the pressure wheel 79; an energy storage spring 791, which is removably arranged on the energy storage rod 78; Next, the overall use principle of the energy storage trigger component 7 is further explained. When the staff opens the molding upper mold 64 and moves it downward once, the step block 77 can be driven to move downward synchronously. After the step block 77 moves downward, the pressure wheel 79 can be driven to move leftward. During the process of the pressure wheel 79 moving leftward, the tooth plate 792 can be made to move leftward for the first time. During the process of the tooth plate 792 moving leftward for the first time, the edge pressing component 8 can be driven to perform positive edge pressing operation on the rubber material strip that has not been hot-pressed. When the molding upper mold 64 moves downward for the second time, the tooth plate 792 can be driven to continue to move leftward, so as to drive the edge pressing component 8 to move downward again, so as to continue to perform the side edge pressing operation after completing the positive edge pressing operation on the rubber material strip. In some embodiments, more specifically, the step block 77 has a first step, a second step and a blocking surface, an inclined slope on the first step, and a second inclined slope on the second step, and in the initial position, the pressure wheel 79 and the lowest point of the first step are in conflict with each other; Next, when the hot press formed component 6 is displaced once, the pressing wheel 79 can be driven to move along the lowest point of the first step toward the first inclined slope and abut against the lowest point of the second step; when the hot press formed component 6 is displaced twice, the pressing wheel 79 can be driven to move along the lowest point of the second step toward the second inclined slope and abut against the blocking surface; Due to the continuous arrangement of the first step and the second step, on the one hand, the energy storage spring 791 can move in the state of compression to the expansion and contraction trend, so that the energy storage spring 791 can move toward the second step when the first step moves down. On the other hand, through this ingenious design, the positive edge pressing operation of the rubber part that has not been hot pressed can be completed during the hot pressing forming process. On the other hand, during the process of conversion from the first step to the second step, the edge pressing member 8 can be moved down again to complete the edge pressing operation on both sides of the rubber strip that has not been hot pressed. In addition, through the first step and the second step The arrangement of the ladder can also realize independent control of the positive edge pressing operation of the material strip by actively contacting the second step or the first step by turning on the fourth electric cylinder 73. By turning on the fourth electric cylinder 73, the energy storage spring 791 can be moved up so that 793 directly contacts the second step, which is equivalent to the edge pressing component 8 having only a single descending operation, which is equivalent to only being able to independently control the positive edge pressing operation of the rubber material strip once. In addition, the energy storage spring 791 can be prevented from contacting the second step or the first step by turning on the fourth electric cylinder 73 to release the start of the edge pressing component 8.

[0026] In some embodiments, more specifically, the energy storage spring 791 is located between the pressure wheel 79 and the connecting substrate 76. When the pressure wheel 79 and the lowest point of the first step collide with each other, the energy storage spring 791 is in a compression trend. There is also a patch on the end of the energy storage rod 78 that passes through the connecting substrate 76.

[0027] Next, the edge pressing member 8 is given a more specific structure and construction as a whole for further explanation. The edge pressing member 8 includes a machine frame 81, which is arranged on the workbench 1, and has a top plate 82 on the machine frame 81; a short shaft 821, which is rotatably arranged on the top plate 82, and a driving wheel 822 and a first driven wheel 823 are rotatably arranged on the short shaft 821, and a belt 824 is sleeved on the first driven wheel 823; a screw rod 83, which is rotatably arranged in the machine frame 81, and the screw rod 83 can pass through the top plate 82, and the screw rod 83 is provided with a belt 824. A second driven wheel 84 is arranged on the frame 81, and the second driven wheel 84 is passed by the belt 824; a ball base 85 is slidably arranged in the frame 81, and the ball base 85 is passed through by the screw 83; an extension plate 86 is arranged at one end of the ball base 85, and two sets of edge pressing members 87 are arranged on the extension plate 86; a tail rod 88 is arranged at the other end of the ball base 85; an extension frame 89 is arranged on the side of the frame 81, and a trigger rod 891 is slidably arranged in the extension frame 89, and a slope 892 is provided at one end of the trigger rod 891; Next, the overall use principle of the edge holding component 8 is further explained. When the molding upper mold 64 moves downward once, it can trigger the tooth plate 792 to move left, and then the tooth plate 792 drives the driving wheel 822 to rotate to drive the second driven wheel 84 to rotate. After the second driven wheel 84 rotates, it can synchronously drive the ball base 85 and the edge holding member 87 to move downward. After the edge holding member 87 moves downward, it can enter into the molding lower mold 54 to complete the positive edge holding operation of the un-hot-pressed rubber material strip, so as to solve the problem that the un-hot-pressed rubber material strip is wrinkled and uneven and cannot be filled into the molding lower mold 54.

[0028] Next, a more specific structure and construction of the edge clamping member 87 is given for further explanation. The edge clamping member 87 includes an edge clamping column 871, which is arranged on the extension plate 86.
