The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0035] For this explanation, in the present technical solution, the linear drive 3 adopts the existing technology and is a common mechanical device for converting rotational motion into linear motion. Its key components include a motor, a lead screw, a nut, a guide rail, a slider, etc. Its core working principle is to drive the lead screw to rotate by a motor, and the nut on the lead screw moves along the axial direction of the lead screw during the rotation process, thereby converting the rotational motion into linear motion. The nut is connected to the slider, and the slider slides along the guide rail to push the load to achieve linear motion;

[0036] The discharge switch 6 includes a guide block 61 fixedly arranged on the inner wall of the discharge port of the storage hopper 2, and a baffle 62 is slidably inserted into the bottom end of the discharge port of the storage hopper 2. The baffle 62 is composed of two groups of straight plates, and the two groups of plates are vertically distributed. The length and width of the straight plates in the horizontal state are greater than the length and width of the discharge port of the storage hopper 2. A limit block 63 is fixedly connected to the baffle 62, and the limit block 63 is arranged in the storage hopper 2. The cross-sections of the guide block 61 and the limit block 63 are both triangular. The guide block 61 causes the material above it to slide toward the limit block 63. The two right-angled sides of the limit block 63 are respectively located at the bottom end of the limit block 63 and one side of the guide block 61. A limit frame 64 is arranged outside the hopper 2, and one end of the storage hopper 2 passes through the discharge port of the storage hopper 2 and is fixedly connected to the side end of the baffle 62. The limit frame 64 is U-shaped, and a spring 65 is fixedly connected to one side of the outside of the storage hopper 2. One end of the spring 65 is fixedly connected to the vertical straight plate in the baffle 62. A push plate 66 is arranged on one side of the vertical straight plate in the baffle 62, and the bottom end of the push plate 66 is slidably plugged with the baffle 62. The push plate 66 is T-shaped, and a push rod 67 is arranged on the top of the feeding box 7. The top end of the push rod 67 and the bottom end of the push plate 66 are in the same horizontal plane, and the contact surface between the T-shaped push plate 66 and the push rod 67 is an arc surface;

[0037] When the linear drive 3 drives the feeding box 7 to move toward the mixing barrel 4, the push rod 67 arranged at the top of the feeding box 7 will abut against the push plate 66 and push the push plate 66 to move toward the feeding box 7, so that the push plate 66 drives the baffle 62 to move until the limit block 63 moves below the guide block 61 and abuts against the inner wall of the storage hopper 2. At this time, the limit frame 64 is inserted into the storage hopper 2 and abuts against the outer side of the storage hopper 2, so that the material in the storage hopper 2 is discharged through the hollow part of the limit frame 64 in the storage hopper 2 and falls into the feeding box 7. As the feeding box 7 continues to move, The push plate 66 is moved, and due to the abutment restriction of the limit frame 64 and the limit block 63 with the storage hopper 2 respectively, the push plate 66 cannot move, and under the action of the abutment, the force is decomposed into an upward force, so that the push plate 66 moves upward and no longer contacts the push rod 67, so that the feeding box 7 passes through here. At this time, due to the movement of the push plate 66, the stretched spring 65 recovers its original length, driving the baffle 62 to reset, until the limit block 63 abuts against the inner wall of the storage hopper 2 on the other side, and the limit frame 64 moves out of the storage hopper 2 discharge port, so that the baffle 62 blocks the storage hopper 2 discharge port again.

[0038] Reference Figures 6 to 9 , the feeding box 7 includes a fixing ear 71 fixedly connected to the movable end of the linear drive 3, one side of the fixing ear 71 is fixedly connected to a material receiving barrel 72, two groups of fixing ears 71 are provided, which are symmetrically distributed on both sides of the material receiving barrel 72, the bottom ends of the push rods 67 are respectively fixedly connected to a group of fixing ears 71, and a connecting frame 73 is fixedly connected to the outer side of the material receiving barrel 72, sliding grooves are provided on both sides of the connecting frame 73, and a limiting plate 74 is slidably inserted in the connecting frame 73, and the top of the limiting plate 74 is fitted with the bottom end of the material receiving barrel 72, and the limiting plate 74 is I-shaped and consists of a group of large straight plates and four groups of small straight plates, wherein two groups of symmetrical small straight plates are slidably inserted into the two groups of sliding grooves in the connecting frame 73, respectively, and a discharging groove 41 is provided through the side end of the mixing barrel 4, and the discharging grooves 41 are provided with multiple groups, which are evenly distributed on the side ends of the mixing barrel 4. The bottom end of the material receiving box 7 is fixedly connected to a discharge base 42, and the discharge base 42 is conical. A receiving plate 43 is fixedly connected to the side end of the mixing barrel 4. The receiving plate 43 is in an inclined state, and its lowest end is connected to the mixing barrel 4. The highest end of the receiving plate 43 is in the same horizontal plane as the limiting plate 74, and the width of the receiving plate 43 is greater than the diameter of the receiving barrel 72. When the linear drive 3 drives the feeding box 7 to move toward the mixing barrel 4, the limiting plate 74 at the bottom of the feeding box 7 abuts against the highest point of the receiving plate 43 at the side end of the mixing barrel 4. Under the abutment action, the receiving plate 43 pushes the limiting plate 74 to slide in the sliding groove on the connecting frame 73. After the limiting plate 74 slides, the bottom end of the receiving barrel 72 is exposed, so that the material in the receiving barrel 72 can be discharged and fall on the receiving plate 43, and then the material passes through the inclined surface of the receiving plate 43 and falls into the mixing barrel 4.

[0039] The above scheme is adopted: the discharge of materials in the receiving barrel 72 can be accurately controlled through the cooperation of the limiting plate 74 and the receiving plate 43. This cooperation mode is closely connected with other components and work processes of the feeding device. In the process of the feeding box 7 moving to the mixing barrel 4 to feed and reset, the limiting plate 74 and the receiving plate 43 work in a specific order and manner, ensuring the smooth progress of the entire feeding and mixing process, making the various components work together, and improving the overall work efficiency and stability of the rubber hose processing feeding device.

[0040] Reference Figures 6 to 8 The mixing device 8 includes a support block 81 fixedly connected to the top of a group of fixed ears 71, a rack 82 is fixedly connected to the top of the support block 81, and the rack 82 is made of flexible material and can be bent. The side end of the mixing barrel 4 is fixedly connected to a support block 83, and the support block 83 is provided with two groups, which are symmetrically distributed on the side end of the mixing barrel 4. The top of the support block 83 is fixedly connected to a limiting frame 84, and the limiting frame 84 is J-shaped. The limiting frame 84 is slidably plugged with the rack 82. Under the guidance of the limiting frame 84, the rack 82 is bent. The top of the other set of fixed ears 71 is fixedly connected to a support block 3 85, and the top of the support block 3 85 is slidably plugged with the bottom of the limiting frame 84. The bottom of the mixing barrel 4 is rotatably connected to a rotating rod 87, and one end of the rotating rod 87 passes through the discharge base 42. The top of the rotating rod 87 is fixedly connected to a gear 86, and the bottom of the gear 86 is rotatably connected to the top of the mixing barrel 4. The gear 86 and the rack 82 are meshed and connected. The outer side of the rotating rod 87 is fixedly connected to a mixing plate 88, and the mixing plate 88 is spirally wound around the outer side of the rotating rod 87. On the side, the bottom end of the mixing plate 88 abuts against the top end of the discharge base 42. There are two groups of mixing plates 88, which are symmetrically distributed on the outside of the rotating rod 87. There are multiple groups of material dropping grooves 89 on the mixing plates 88, which are staggered on the two groups of mixing plates 88. When the linear drive 3 drives the feeding box 7 to move, the rack 82 on the support block 81 fixedly connected to the top of the fixed ear 71 also moves accordingly. Since the rack 82 is made of flexible material and can be bent, and is slidably plugged with the J-shaped limiting frame 84, Under the guidance of the limiting frame 84, the rack 82 will bend and mesh with the gear 86. During the resetting process of the feeding box 7, the rack 82 is pulled out, and the gear 86 meshing with the rack 82 will rotate accordingly, so that the gear 86 drives the rotating rod 87 to rotate, and the spiral mixing plate 88 fixedly connected to the outside of the rotating rod 87 will also rotate, scooping up the material on the top of the discharge base 42, and moving upward under the action of the spiral shape of the mixing plate 88, and the material falls from the drop chute 89 on the mixing plate 88.

[0041] The above scheme is adopted: through the linkage of components such as the rack 82 and the gear 86, the materials in the mixing barrel 4 can be efficiently stirred and mixed, and the spiral mixing plate 88 and the staggered drop troughs 89 are used to fully mix the materials to ensure the uniformity of the mixing. The mixing device 8 is associated with the movement of the feeding box 7, and the mixing operation is automatically performed during the resetting process of the feeding box 7. No additional driving device and complex control process are required, thereby realizing the coordination of the feeding and mixing processes and improving the working efficiency and automation level of the entire feeding device.

[0042] Reference Fig.10 The discharging device 9 includes a rotating shaft 91 fixedly connected to the bottom end of the fixed frame 1, and a blocking rod 92 and a blocking rod 93 are rotatably connected to the outer side of the rotating shaft 91. The two groups of blocking rods 92 and 93 are distributed in an X shape. The blocking rods 92 and 93 are composed of a group of L-shaped rods and a group of C-shaped plates, wherein the size of the C-shaped plates is larger than the discharging trough 41, so that the C-shaped plates in the blocking rods 92 and 93 can block and block the discharging trough 41, and the blocking rods 92 and 93 are arranged on the outer side of the blocking rods. 93 top, the side end of the stop rod 93 is fixedly connected with a spring 94, one end of the spring 94 is fixedly connected to the inner wall of the fixed frame 1, one end of the stop rod 93 is fixedly connected with an opening and closing rod 95, and one side of the stop rod 92 is also provided with a spring 94, and one end of the stop rod 92 is also fixedly connected with an opening and closing rod 95, and the spring 94 is provided with six groups, which are symmetrically distributed on one side of the stop rod 92 and the stop rod 93, and the opening and closing rods 95 on the stop rod 92 and the stop rod 93 are distributed in an eight-shaped shape, and the eight-shaped shape The maximum spacing between the two groups of opening and closing rods 95 distributed in the figure eight shape is greater than the diameter of the receiving barrel 72. When the linear drive 3 drives the feeding box 7 to move to the other side of the mixing barrel 4, the receiving barrel 72 in the feeding box 7 is inserted between the two groups of opening and closing rods 95 distributed in the figure eight shape, and the two groups of opening and closing rods 95 are stretched open, so that the blocking rod 1 92 and the blocking rod 2 93 rotate around the rotating shaft 91, and the discharge groove 41 on the mixing barrel 4 is exposed, and the uniformly mixed materials in the mixing barrel 4 are discharged into the feeding hopper 5 through the discharge groove 41, and enter the feeding hopper 5 through the feeding hopper 5. After the material is discharged from the mixing barrel 4 and the feeding box 7 is moved out from between the two sets of opening and closing rods 95 distributed in an eight-shaped pattern, the blocking rod 1 92 and the blocking rod 2 93 are rotated in the opposite direction around the rotating shaft 91 and reset under the action of the spring 2 94, and the C-shaped plate blocks the discharge trough 41 again to prevent the material from continuing to be discharged.

[0043] The above scheme is adopted: the expansion and resetting of the opening and closing rod 95 are controlled by the movement of the feeding box 7, and then the blocking and release of the discharge chute 41 by the blocking rod 1 92 and the blocking rod 2 93 are accurately controlled, so as to realize the precise control of the material discharge in the mixing barrel 4 and ensure that the amount of material discharged into the feeding hopper 5 meets the processing requirements. The blocking rod 1 92 and the blocking rod 2 93 are distributed in an X shape, and the spring 2 94 provides elastic support. This structure enables the device to maintain good stability during operation, and can accurately achieve the blocking and release of the discharge chute 41 in multiple opening and closing actions, reducing the possibility of malfunction. The maximum spacing of the opening and closing rods 95 with an eight-shaped distribution is larger than the diameter of the receiving barrel 72, and can cooperate well with the receiving barrel 72 of the feeding box 7, ensuring that the receiving barrel 72 can be smoothly inserted into the expansion opening and closing rod 95 to realize the discharging operation, and has strong adaptability to other components of the entire feeding device, ensuring the smooth progress of the feeding and discharging process.

[0044] The working principle of the present invention is as follows: when in use, the linear drive 3 is first started to drive the feeding box 7 to move toward the mixing barrel 4. During the movement, the push rod 67 arranged at the top of the feeding box 7 will abut against the arc surface at the bottom end of the push plate 66, and push the push plate 66 to move toward the feeding box 7, so that the push plate 66 drives the baffle 62 to move until the limit block 63 moves below the guide block 61 and abuts against the inner wall of the storage hopper 2. At this time, the limit frame 64 is inserted into the storage hopper 2 and abuts against the outer side of the storage hopper 2, so that the material in the storage hopper 2 is discharged through the hollow part of the limit frame 64 in the storage hopper 2 and falls into the feeding box 7. With the continuous movement of the feeding box 7, and due to the abutment restriction of the limit frame 64 and the limit block 63 with the storage hopper 2, the push plate 66 cannot move. Under the action of abutment, the force is decomposed into an upward force, so that the push plate 66 moves upward and no longer contacts the push rod 67, so that the feeding box 7 passes through here. At this time, due to the movement of the push plate 66, the stretched spring 65 recovers its original length, driving the baffle 62 to reset until the limit block 63 abuts against the inner wall of the storage hopper 2 on the other side, and the limit frame 64 moves out of the discharge port of the storage hopper 2, so that the baffle 62 blocks the discharge port of the storage hopper 2 again, and when the feeding box 7 passes through here, the pushed push plate 66 falls again due to gravity and resets. By controlling the residence time of the feeding box 7 under each group of storage hoppers 2 by the linear drive 3, the discharge amount of the material in each group of storage hoppers 2 can be controlled, so that the various types of raw materials in the feeding box 7 can be distributed proportionally. The linear drive 3 continues to drive the feeding box 7 to move. When the limiting plate 74 at the bottom of the feeding box 7 abuts against the highest point of the receiving plate 43 at the side end of the mixing barrel 4, under the abutting action, the receiving plate 43 will push the limiting plate 74 to move in the sliding groove on the connecting frame 73, exposing the bottom end of the receiving barrel 72, so that the material in the receiving barrel 72 is discharged and falls on the receiving plate 43, and falls into the mixing barrel 4 through the inclined surface of the receiving plate 43. When the material in the receiving barrel 72 is completely discharged, the linear drive 3 controls the feeding box 7 to reset. During the resetting process, the push rod 67 on the fixed ear 71 will abut against the push plate 66 again. When abutting, one end of the limit block 63 abuts against the inner wall of the storage hopper 2, so that the baffle 62 will not move, and the limit block 63 abuts against the inner wall of the storage hopper 2 Under the action of , the push plate 66 moves up again to allow the feeding box 7 to pass, and after the feeding box 7 passes, it is reset due to gravity, and during the reset process of the feeding box 7, the feeding box 7 will pull out the rack 82 inserted into the limiting frame 84, and as the rack 82 is pulled out, the gear 86 meshing with the rack 82 is driven to rotate, so that the mixing plate 88 rotates accordingly, scooping up the material on the top of the discharge base 42, and moving upward under the spiral shape of the mixing plate 88, and falling from the drop groove 89, with the rotation of the two groups of mixing plates 88, and under the action of the drop grooves 89 staggered on the two groups of mixing plates 88, the materials in the mixing barrel 4 are mixed evenly, when the reset of the feeding box 7 is completed, the linear drive 3 continues to drive the feeding box 7 to move to the other side of the mixing barrel 4,The receiving barrel 72 in the movable feeding box 7 is inserted between the two groups of opening and closing rods 95 distributed in an eight-shaped shape, and the two groups of opening and closing rods 95 are stretched open to expose the discharge groove 41 on the mixing barrel 4, and the evenly mixed materials in the mixing barrel 4 are discharged into the feed hopper 5 through the discharge groove 41, and enter the processing equipment through the feed hopper 5. As the feeding box 7 continues to move, one end of the limiting plate 74 previously pushed by the receiving plate 43 abuts against the inner side of the blocking rod, so that the receiving plate 43 is reset and re-connected to the bottom end of the barrel 72 for blocking; through the abutment of the push rod 67 and the push plate 66 in the discharge switch 6, and the baffle 62 and the limit block The mutual cooperation of 63 and the limit frame 64 can accurately control the discharging timing and amount of the storage hopper 2, ensuring that the amount of material discharged each time meets the processing requirements. The setting of the spring 65 enables the baffle 62 to automatically reset after the feeding box 7 passes through, and the discharging port of the storage hopper 2 is blocked again, without additional manual operation or complex control mechanism, which improves the automation and convenience of the feeding device. The mixing plate 88 is spirally wound around the outer side of the rotating rod 87 in the mixing device 8, and multiple groups of drop grooves 89 are staggered on the two groups of mixing plates 88. When the gear 86 drives the rotating rod 87 to rotate The mixing plate 88 can scoop up the material on the top of the discharge base 42 and move it upward, and then drop it from the drop chute 89, so as to achieve efficient and uniform mixing of the material in the mixing barrel 4, and ensure the mixing quality of the raw materials for rubber hose processing. The meshing connection between the rack 82 and the gear 86 and the guidance of the rack 82 by the limiting frame 84 can convert the movement of the feeding box 7 into the rotation of the mixing plate 88, without the need for an additional power source, simplifying the power system of the equipment, reducing energy consumption and equipment costs, and through the cooperation of the opening and closing rod 95 in the discharge device 9 and the receiving barrel 72 of the feeding box 7, it can be flexibly controlled. The timing of discharging the mixing barrel 4 is controlled to ensure that the evenly mixed materials are discharged into the feed hopper 5 at the appropriate time and enter the processing equipment for subsequent processing. The setting of the second spring 94 enables the blocking rod 1 92 and the blocking rod 2 93 to automatically reset after the feeding box 7 leaves, and continue to block the discharge trough 41 to prevent the material from leaking when it is not needed to be discharged. At the same time, the cooperation between the limiting plate 74 and the blocking rod can automatically reset the limiting plate 74, without the need to set up additional complex power or control elements to specifically operate the limiting plate 74 to return to its original position, which greatly simplifies the overall structure of the device and reduces the manufacturing cost and failure risk of the equipment.
