Description

Technical Field

[0001] The utility model relates to the technical field of tire production equipment, in particular to a feeding seat for an extruder and an extruder. Background Art

[0002] Special tire winding production lines usually include extruders, presses, coolers, conveyors and winding machines. The extruder includes a feeding seat and an extruder head. The rubber is fed from the feeding seat into the extruder and then extruded from its head. It then enters the press to be calendered and formed into a rubber strip. After being cooled in the cooler, it is conveyed to the winding machine by the conveyor. The winding machine uses the cooled rubber strip to wind the tire blank to complete the tire winding process. On the one hand, some components inside the feeding seat will gradually wear out as the working time increases and need to be checked regularly. On the other hand, after each production work is completed, rubber is likely to remain in the feeding seat and needs to be cleaned. For this reason, the existing feeding seats in the industry are provided with feeding doors on the side walls. Users can open the feeding doors to check the components in the feeding seat or clean the residual rubber in the feeding seat. In the prior art, the feeding door needs to be opened manually by the user. For example, in the rubber extruder disclosed in patent document CN202480357U, the bottom edge of the door seat assembly (i.e., the feeding door) is pivotally mounted on the feeding seat body, and an opening screw is installed on the top edge of the door seat assembly. The length of the screw is greater than the thickness of the door seat assembly. When the door seat assembly is normally closed, the screw does not fully extend into the door seat assembly and the end just touches the feeding seat body. When the door seat assembly needs to be opened, the user can rotate the screw to make it continue to extend into the door seat assembly. Since the end of the screw has originally rested on the feeding seat body, when the screw continues to extend into the door seat assembly, the screw will hold up the feeding seat body and cannot move forward, so that the door seat assembly is subjected to the reaction force of the feeding seat body and rotates around the pivot to open, and then the user manually pries open the door seat assembly. Summary of the invention

[0003] The utility model aims to provide a feeding seat for an extruder and an extruder provided with the feeding seat. The feeding seat can automatically open a feeding door without manual operation by a user.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with specific implementation methods.

[0021] Extruder Figure 1 As shown, it includes a feeding seat 1, a barrel 2 and a die 3. The inner cavity of the feeding seat 1 is connected to the beginning of the barrel 2, and the end of the barrel 2 is connected to the die 3. The die 3 includes a die body 39 and a die cover 30, and an extrusion port 302 is opened on the front side of the die cover 30. During operation, the rubber material is fed from the feeding funnel 15 of the feeding seat 1, moves to the extruder die 3 through the barrel 2, and then extruded from the extrusion port 302 on the die cover 30, and moved to the production equipment of the next process of the tire winding production line.

[0022] Feeding seat 1 Figure 2 , 3 As shown, it includes a main body seat 10 and a feeding door 11 hinged on the main body seat 10. The feeding seat 1 is provided with a hydraulic cylinder 14, the cylinder body of the hydraulic cylinder 14 is fixed on the main body seat 10, and the piston rod 13 thereof is hinged on the hinge 12 between the feeding door 11 and the main body seat 10. In the initial state, the piston rod 13 of the hydraulic cylinder 14 extends out to a preset length, and the feeding door 11 is folded on the main body seat 10. After the production work of the extruder is completed, the maintenance personnel need to clean up the residual rubber in the feeding seat 1, start the hydraulic cylinder 14, and the hydraulic cylinder 14 acts as a driving device to retract the piston rod 13, thereby pulling the feeding door 11 to rotate and open around the pivot. Specifically: to rotate and open the feeding door 11, the end of the piston rod 13 of the hydraulic cylinder 14 needs to pull the hinge 12 to rotate, so as Figure 3 As shown, the cylinder body of the hydraulic cylinder 14 is designed to be fixed on the main body seat 10 by means of an articulation. In the process of driving the feeding door 11 to rotate and open, the hydraulic cylinder 14 can swing around the hinge point between the cylinder body start end and the main body seat 10, so that the end of the piston rod 13 of the hydraulic cylinder 14 can pull the hinge part 12 to rotate, thereby driving the feeding door 11 to rotate and open around the pivot, as shown in FIG. Figure 4 , 5As shown, the inner cavity of the feeding seat 1 is exposed, and the maintenance personnel can clean the residual rubber in the inner cavity of the feeding seat 1. If the maintenance personnel need to inspect the components in the feeding seat 1, they can open the feeding door 11 in the same way to expose the inner cavity of the feeding seat 1, and then inspect the components in the feeding seat 1.

[0023] like Figure 6 , 7 As shown, the machine head body 39 is provided with left and right C-shaped locking members 31 and 32 on the left and right sides respectively, and the upper ends of the left and right C-shaped locking members 31 and 32 are fixed on the machine head body 39. Figure 8 As shown, the outer peripheral walls of the machine head body 39 and the machine head cover 30 are respectively protruded with annular locking edges 301 and 391. When the lower ends of the left and right C-shaped locking members 31 and 32 are tightened, the locking edges 301 and 391 of the machine head body 39 and the machine head cover 30 will be embedded in the left and right C-shaped locking members 31 and 32, that is, the left and right C-shaped locking members 31 and 32 fix the locking edges 301 and 391 of the machine head body 39 and the machine head cover 30 together, thereby locking the machine head body 39 and the machine head cover 30. Figure 6 , 7 As shown, the extruder head is provided with left and right cylinders 33 and 34 for driving the left and right C-type locking members 31 and 32 respectively. The cylinder body of the right cylinder 34 is fixed on the head body 39, and the piston rod of the right cylinder 34 is connected to the right C-type locking member 32 through the second right connecting rod 38. Specifically, the piston rod of the right cylinder 34 is hinged to the lower end of the second right connecting rod 38, and the upper end of the second right connecting rod 38 is hinged to the movable end of the right C-type locking member 32; the extruder head is provided with a first right connecting rod 36 to assist in defining the path of the piston rod end of the right cylinder 34. The left end of the first right connecting rod 36 is hinged to the head body 39 as a fixed end, and the right end is hinged to the hinge point between the right cylinder 34 and the second right connecting rod 38 as a movable end. The first right connecting rod 36 and the second right connecting rod 38 constitute a right connecting rod device for the right cylinder 34 to drive the right C-type locking member 32. Similarly, the left cylinder 33 also drives the left C-type locking member 31 through the left connecting rod device composed of the first left connecting rod 35 and the second left connecting rod 37. The connection structure between the first left connecting rod 35, the second left connecting rod 37 and the left cylinder 33 and the left C-type locking member 31 and the connection structure between the first right connecting rod 36, the second right connecting rod 38 and the right cylinder 34 and the right C-type locking member 32 are symmetrically arranged. In the initial state, the piston rods of the left cylinder 33 and the right cylinder 34 are respectively extended to a preset length, and the lower ends of the left and right C-type locking members 31 and 32 are tightened through the connecting rod device. In practice, the states of the left and C-type locking members 31 and 32 are always kept synchronized; Figure 6 , 7For the convenience of comparison, the left C-type locking member 31 is drawn as a tightened state, and the right C-type locking member 31 is drawn as an open state. In practice, this state will not occur. After the extruder production work is completed, the maintenance personnel need to clean the inner cavity of the die head. They start the left cylinder 33 and the right cylinder 34 through the control buttons of the cylinder 33 and the cylinder 34 to simultaneously drive the left and right C-type locking members 31 and 32 to open. Specifically, Figure 6 As shown, the cylinder bodies of the left cylinder 33 and the right cylinder 34 are fixed to the machine head body 39 by means of a hinge. The right cylinder 34 retracts the piston rod, pulling the first right connecting rod 36 to rotate downward around its fixed end. During this process, the right cylinder 34 rotates around the hinge point between the starting end of its cylinder body and the machine head body 39, so that the piston rod of the right cylinder 34 can pull the movable end of the first right connecting rod 36 to rotate downward; the downward rotation of the first right connecting rod 36 around its fixed end drives the second right connecting rod 38 to move with the movable end of the first right connecting rod 36, thereby pulling the right C-type locking member 32 to rotate and open around its upper end. The open state is shown in FIG. Figure 7 The left C-shaped locking member 31 is opened by a symmetrical action with the right C-shaped locking member 32. The maintenance personnel can hold the handle 303 of the machine head cover 30 to open the machine head cover 30, and then the inner cavity of the machine head 3 can be cleaned.

[0024] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
