In the above technical scheme, the base 1 and the fixing frame 21 are square closed frames, four sides of the fixing frame 21 are in one-to-one correspondence with four sides of the base 1, two diagonal rods 61 of the supporting frame 6 are respectively arranged on two opposite sides of the base 1 and are connected with the corresponding sides of the fixing frame 21, a supporting rod 7 is arranged between the two diagonal rods 61 and is centrally symmetrical relative to the supporting rod 7, so that the fixing frame 21 is stably supported, when the lifting device 5 is used for changing the height of the fixing frame 21, the two diagonal rods 61 synchronously slide in opposite directions or outwards by taking the supporting rod 7 as the center, the supporting center of gravity of the fixing frame 21 is always kept on the vertical plane where the supporting rod 7 is located, and the supporting center of gravity of the fixing frame 21 is not changed due to the movement of the diagonal rods 61, so that the supporting frame 6 can also provide stable supporting force for the fixing frame 21 in the process of changing the internal shape. The support frame has simple structure and easy assembly, can provide stable supporting force for the fixing frame 21 while adapting to the height change of the fixing frame, and improves the stability of the whole material supporting mechanism.
In another aspect, the novel material supporting mechanism, the first bracket 22 and the second bracket 32 are standard bracket units, which includes: a slide rail 42 provided along the feeding direction; the rollers 41 are disposed on the sliding rail 42 at intervals along the length direction of the sliding rail 42, and the upper portion of any roller 41 protrudes out of the upper surface of the sliding rail 42 and is rotatably connected with the sliding rail 42 through a rotating shaft 43. The sliding rail 42 is preferably a fluent strip, the roller 41 is preferably a Fulai wheel, when the material is placed on the first bracket 22 and the second bracket 32, the roller 41 slides towards the direction of the mold under the action of gravity, the contact area between the material and the bracket can be effectively reduced by the roller 41 structure arranged on the surface of the bracket at intervals, meanwhile, the roller 41 receives the friction force from the material in the process of relative movement of the material, which is the same as the movement direction of the material, and rotates in situ along the feeding direction, so that the sliding friction between the material and the bracket is converted into rolling friction, the friction coefficient between the material and the bracket is greatly reduced, the material can be transported from the material supporting mechanism to the mold more smoothly, and the material transportation efficiency is improved.
In another aspect, the second bracket 32 further includes an auxiliary device, which is disposed on the sliding rail 42 and located directly below the roller 41 adjacent to the feeding side, and the auxiliary device includes: a driving motor 81 fixed to the slide rail 42 at one side of the roller 41 by a bracket, an output shaft of the driving motor 81 being parallel to the rotation shaft 43; and a turntable 82 fixedly sleeved on the output shaft of the driving motor 81 and positioned right below the roller 41, wherein the top end of the turntable 82 is abutted with the bottom end of the roller 41. In actual material processing, especially in coil stock processing, because there are the quality of the material to be processed, the volume is great, the surface that contacts with holding in the palm material mechanism is rough etc. circumstances, and in order to guarantee after the one end of material is transported to the mould feed inlet, the other end can not take place problem such as deformation in the transportation, the inclination (slope) that makes the material can be slided to the mould that bracket one 22 and bracket two 32 set up by oneself is less, easily lead to the material to overcome static friction or other resistance with whole bracket, thereby can't be smooth to the automatic problem of transporting of mould department. To solve the above problem, an auxiliary device is added to the second bracket 32, wherein the driving motor 81 is smaller in size and can be mounted on the sliding rail 42 without affecting the original structure of the second bracket 32, and the turntable 82 is driven to rotate to drive the roller 41 to rotate, so that an additional initial pushing force is applied to the material, and the material can be smoothly moved to the position of the mold. The rotary table 82 is sleeved on the output shaft of the driving motor 81, in order to ensure the stability of the rotary table 82 in rotation, an extension rod is arranged on the other side (the side far away from the driving motor 81) of the rotary table 82, one end of the extension rod is fixed at the end part of the output shaft, the other end of the extension rod extends to the outer side of the sliding rail 42 along the length direction of the output shaft of the driving motor 81 and is rotationally connected with the side wall of the sliding rail 42, thus, supporting structures (a bracket for fixing the driving motor 81 and the side wall of the sliding rail 42) are arranged at two ends of the rotating shaft 43 of the rotary table 82, and the rotary table 82 can stably rotate by taking a fixed height as an axle center and drives the rolling wheels 41 to roll.
In the above technical scheme, on the basis of not changing the original structure of the second bracket 32, the roller 41 at the initial position is optimized, when obvious problems such as obvious transportation clamping stagnation and slowness occur to materials, the control device electrically connected with the auxiliary device controls the driving motor 81 to work, so that the driving motor 81 drives the turntable 82 to synchronously rotate in the direction opposite to the feeding direction, under the friction force of the turntable 82 to the roller 41, the roller 41 is driven to rotate in the feeding direction, thereby driving the materials above the roller 41 to move in the feeding direction, at the moment, the static friction force between the materials and the second bracket is converted into a dynamic friction force, and the friction force is reduced, therefore, after the materials are pushed by the rollers adjacent to the feeding side, the materials can be transported to the mold normally along the feeding direction without other acting forces, and the auxiliary device is only arranged below the rollers adjacent to the feeding side, so that the effect of assisting the movement of the materials can be achieved. The novel material supporting mechanism can adapt to materials of various different specifications and smoothly transmit the materials to the feeding hole of the die, and meanwhile, the problems that a large driving device is complex in structure, long in assembly and wiring time consumption, high in cost and the like are avoided.
In another technical scheme, in the novel material supporting mechanism, two opposite penetrating grooves 44 are formed in one end of the sliding rail 42 located at the feeding side, any penetrating groove 44 is formed along the height direction, the height of the penetrating groove 44 is larger than the diameter of the rotating shaft 43, and the rotating shaft 43 of the roller 41 adjacent to the feeding side is placed in the two penetrating grooves 44; the turntable 82 is an eccentric disk; the roller 41 adjacent to the feeding side reciprocates up and down along the through groove 44 under the driving of the driving motor 81. Specifically, in the initial state (the driving motor 81 has not yet started to work), the eccentric disc forms a cam structure upwards, that is, the distance from the axis of the eccentric disc to the top end of the eccentric disc is greater than the distance from the axis of the eccentric disc to the bottom end of the eccentric disc, at this time, the rotating shafts 43 of the rollers 41 adjacent to the feeding side are located at the top ends of the two through grooves 44, so that when the driving motor 81 starts to work, the eccentric disc rotates synchronously with the driving motor 81, and because the radius of the upper part of the eccentric disc is greater in the initial state, the distance from the axis of the eccentric disc to the bottom end of the rollers 41 is gradually reduced in the process of rotating the first half circle, and the rotating shafts 43 of the rollers 41 move downwards along the height direction of the two through grooves 44 under the action of gravity, so that the rollers 41 move downwards synchronously with the rotating shafts 43 while rotating relatively with the rotating shafts 43; the distance from the axle center of the eccentric disc to the bottom end of the roller 41 is gradually increased in the process of rotating the rear half circle, and the roller 41 and the rotating shaft 43 thereof move upwards along the height direction of the two through grooves 44 under the supporting force of the eccentric disc below, so that the roller 41 and the rotating shaft 43 synchronously move upwards while rotating relatively to the rotating shaft 43; when the above rotation process is repeated, the roller 41 and its rotating shaft 43 reciprocate up and down along the through groove 44.
Through auxiliary device, exert along thrust (frictional force) of feeding direction to the material of gyro wheel 41 top and still exert intermittent vertical thrust to the material to form vibrating structure in the gyro wheel 41 department adjacent with the feeding side, the removal of auxiliary material on bracket two 32 that can be better effectively solves the problem that the material jamming and can't smooth removal because of the great or uneven material of material and bracket two contact surface frictional force lead to. In addition, because the rotating shaft 43 is located at the top end of the through groove 44 in the initial state, the height of the roller in the vibration process cannot exceed the height of the roller in the initial state, but in the vertical reciprocating motion, the roller applies an upward thrust to the bottom of the above material through acceleration when returning to the original height, the problem that the deformation is caused by the local stress concentration of the material because the roller protrudes out of the original height is effectively prevented, the processing quality of the material is further ensured, and the adaptability of the novel material supporting mechanism to different materials is improved.
In another technical scheme, the novel material supporting mechanism is characterized in that hooks are arranged at two ends of the second bracket 32. Specifically, the couple that bracket two 32 is close to one end of mould can dismantle with the fixed knot on the mould and be connected, and the couple that bracket two 32 is close to feeding work or material rest one end can dismantle with the fixed knot on the feeding work or material rest and be connected, and two couples are elasticity telescopic structure, and mould and feeding work or material rest all apply elastic tension to bracket two 32 through the couple.
