Description

Technical Field

[0001] The present invention relates to the technical field of slag wire material adding devices, and in particular to a slag wire material adding mechanism. Background Art

[0002] Slag wire material is a building material made from waste slag and waste materials. These waste slag and waste materials usually come from construction sites, demolition projects, manufacturing waste, etc. Through proper treatment and processing, they can be made into slag wire material to reduce waste generation and lower environmental impact.

[0003] Chinese patent publication number CN210210835U discloses a dedicated feeding device for slag wire material, which includes an outer barrel for temporarily storing and releasing the slag wire material, and an inner barrel for positioning a core rod. Positioning members and positioning sheets are used in the inner barrel to position the core rod.

[0004] However, we found in actual use that this method is only applicable to mandrels of a specific size, that is, the mandrel size must match the inner diameter of the inner barrel. If it does not match, not only can it not be guaranteed that the mandrel and the inner barrel will not be displaced relative to each other during the actual production process, but it cannot also guarantee that the mandrel and the inner barrel are coaxial. At the same time, even if the sizes of the mandrel and the inner barrel are adapted, during the process of inserting the mandrel into the inner barrel, either there will be a gap between the mandrel and the positioning sheet to prevent the sheet from scratching the mandrel surface, but this will cause the mandrel and the inner barrel to be misaligned, or there will be no gap between the mandrel and the positioning sheet. Although this can fully ensure the coaxiality of the mandrel and the inner barrel, it will cause the sheet to scratch the side end face of the mandrel, which is not worth the loss.

[0005] Therefore, we believe that there is a need for a feeding device for slag wire material that can adapt to core rods of different sizes and automatically ensure that it is coaxial with the core rod. Summary of the Invention

[0006] In response to the shortcomings of the existing technology, the utility model proposes a feeding mechanism for slag wire material, which has the advantages of ensuring coaxiality with the core rod and being able to adapt to core rods of different sizes, solving the shortcomings of the existing technology device that has a small scope of application and cannot ensure coaxiality between the core rod and the inner barrel.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The cam is secured to the outside of the housing with a plurality of locking plates, each of which is secured to a position about 1 / 4 of the cam face and secured to a bottom of the housing with a plurality of locking plates, each of which is secured to a position about 1 / 4 of the cam face.

[0009] Preferably, a tension spring I is provided at the upper end of each follower rod, and the two axial ends of the tension spring I are movably connected to the corresponding follower rod and the inner wall of the inner shell respectively, and the angle between the central axis of the tension spring I and the horizontal plane is greater than 30°.

[0010] Preferably, when the tension spring I is not affected by external force, the angle between the follower rod and the inner wall of the inner shell is greater than 20° and less than 80°.

[0011] Preferably, the pull rope is a two-section structure, comprising a rope body I and a rope body II arranged upper and lower, a tension spring II being arranged between the rope body I and the rope body II, and the two axial ends of the tension spring II being movably connected to the proximal ends of the rope body I and the rope body II respectively.

[0012] Preferably, the lower end of the positioning block is fixedly connected to a contact pad I made of rubber material, and the outer side of the follower rod is sleeved with a contact pad II made of rubber material, wherein the projection of the contact pad on the outer side of the follower rod away from the inner wall of the inner shell on the vertical plane is an arc-shaped structure.

[0013] Preferably, the upper end of the positioning block is fixedly connected to a threaded rod, a positioning nut is screwed on the outer side of the threaded rod, and the inner wall of the upper end of the inner shell is fixedly connected to a positioning rod, a through hole is opened on the positioning rod, the threaded rod is inserted into the through hole, the positioning nut abuts against the upper end surface of the positioning rod, and the upper end of the threaded rod is fixedly connected to a limiting rod with a polygonal structure projected on the horizontal plane, a limiting ring is sleeved on the outer side of the limiting rod, and the limiting ring is fixedly connected to the inner shell.

[0014] Preferably, the projection of the limiting rod on the horizontal plane completely covers the projection of the threaded rod on the horizontal plane, and the number of the limiting rings is two, and the two limiting rings are coaxially arranged up and down.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model uses a pull rope in conjunction with a positioning ring, so that the projection length of the follower rod on the horizontal plane can be synchronously increased during the downward movement of the positioning block. The use of multiple follower rods to synchronously apply a clamping force to the core rod can not only ensure that no relative movement occurs between the device and the core rod during the production process, but also ensure that the device and the core rod are automatically coaxial, thereby ensuring processing accuracy and improving production efficiency.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Please refer to Figure 1-5 A feeding mechanism for slag wire material comprises an outer shell 1, an inner shell 2 is arranged on the inner side of the outer shell 1, and the outer shell 1 is consistent with the prior art device, which comprises a positioning cylinder for being nested on the outer side of the inner shell 2, and a carrying cylinder for holding the slag wire material is sleeved on the outer side of the positioning cylinder, and the carrying cylinder is a two-section structure, one section of the carrying cylinder is fixedly connected to the positioning cylinder, and the other section of the carrying cylinder is slidably connected to the positioning cylinder. When the slag wire material is filled inside the carrying cylinder, the slag wire material inside the carrying cylinder can be poured to the outside, that is, poured to the surroundings of the inner shell 2, by sliding the carrying cylinder part that is slidably connected to the positioning cylinder.

[0026] It should be noted that a plurality of positioning bolts are screwed onto the upper end of the positioning cylinder, and the positioning bolts are embedded in the positioning cylinder and abut against the upper end surface of the inner shell 2. This can change the distance between the positioning cylinder and the inner shell 2 by rotating the positioning bolts.

[0027] Different from the prior art devices, the present device is provided with a positioning block 12 inside the inner shell 2. By changing the position of the positioning block 12 and cooperating with the positioning bolts, the upper position of the slag line can be made as expected.

[0028] Specifically, the upper end of the positioning block 12 is fixedly connected to the threaded rod 8, and the outer side of the threaded rod 8 is screwed with a positioning nut 9, and the lower end of the positioning nut 9 is abutted with a positioning rod 10, and the positioning rod 10 is fixedly connected to the inner wall of the inner shell 2. At the same time, a through hole is opened on the positioning rod 10 for the threaded rod 8, and the threaded rod 8 is inserted into the through hole. Therefore, in practice, it is only necessary to constrain the threaded rod 8 from rotating, and the upper and lower heights of the threaded rod 8 and the positioning block 12 can be changed by rotating the positioning nut 9.

[0029] Therefore, the device has a limit rod 7 fixedly connected to the upper end of the limit rod 7, the horizontal plane projection of which is a polygonal structure, and a limit ring 6 is sleeved on the outside of the limit rod 7 to limit it. Therefore, it is only necessary to ensure that the limit ring 6 is fixedly connected to the inner shell 2, and the limit ring 6 can be used in conjunction with the limit rod 7 to realize the rotation constraint of the threaded rod 8.

[0030] Furthermore, in order to ensure that the up and down movement trajectory of the threaded rod 8, that is, the movement stroke is in line with expectations, and to avoid the movement stroke of the threaded rod 8 being too short due to the position constraint between the limit ring 6 and the inner wall of the upper end of the positioning cylinder, this device constrains the projection of the limit rod 7 on the horizontal plane to completely cover the projection of the threaded rod 8 on the horizontal plane, and there are two limit rings 6, and the two limit rings 6 are coaxially arranged up and down.

[0031] Furthermore, in order to prevent the positioning block 12 from scratching the surface of the mandrel and causing damage to the mandrel during the contact process between the positioning block 12 and the mandrel, the device is fixedly connected to a rubber contact pad Ⅰ13 at the lower end of the positioning block 12, such as Figure 5As shown, the contact pad I 13 is fixedly connected to the positioning block 12 by a locking bolt. Therefore, the deformable property of the rubber material itself can be utilized to avoid the positioning block 12 from having a hard contact with the core rod.

[0032] It should be noted that, in practice, in addition to using the positioning block 12 to determine the upper end position of the core rod, it is also necessary to ensure that the device is coaxial with the core rod. This can ensure the uniformity of the slag wire material addition and avoid processing errors.

[0033] Therefore, in order to realize automatic coaxial processing of the device and the core rod, the device is rotatably connected to a plurality of follower rods 15 at the lower end of the inner shell 2. When the synchronous rotation of the plurality of follower rods 15 is ensured and the horizontal projection length of the follower rod 15 is changed so that the follower rod 15 abuts against the core rod, the coaxiality between the device and the core rod can be realized by utilizing the joint action of the plurality of follower rods 15.

[0034] Specifically, in this device, a pull rope 4 is fixedly connected to the lower end of each follower rod 15, and the follower rod 15 can be driven to rotate by pulling the pull rope 4.

[0035] At the same time, the device is provided with a plurality of driven rods 11 on the side end surface of the positioning block 12 , and the central axis of each driven rod 11 is perpendicular to the central axis of the inner shell 2 .

[0036] Therefore, by fixing the other end of the constraint rope 4 to the side end face of the driven rod 11, the transmission between the positioning block 12 and the rotation of the follower rod 15 can be achieved during the movement, so that the operator can synchronously realize the disadvantages of the upper end position of the core rod and the coaxial adjustment between the core rod and the inner shell 2.

[0037] It should be noted that, in practice, since the angle between the upper end of the follower rod 15 and the inner wall of the inner shell 2 is less than 90°, in order to achieve that when the positioning block 12 moves downward, the pull rope 4 can apply a downward pulling force to the follower rod 15 from below, forcing the follower rod 15 to rotate downward to increase the projection length on the horizontal plane, the device is circumferentially provided with multiple positioning rings 16 at the upper end of the inner shell 2, and the multiple positioning rings 16 correspond one-to-one to the multiple pull ropes 4, and the height of the positioning ring 16 is greater than the height of the driven rod 11. At this time, by constraining the middle section of the pull rope 4 to surround the corresponding positioning ring 16, the middle section of the pull rope 4 can be subjected to an upward pulling force when the driven rod 11 follows the positioning block 12 to move downward. At this time, in conjunction with the contact position of the pull rope 4 and the driven rod 11, the driven rod 11 can be subjected to a downward pulling force.

[0038] Furthermore, Figure 3As shown, the device is also circumferentially fixed with multiple positioning rings 16 at the lower end of the inner shell 2, and the middle section of the pull rope 4 also surrounds the positioning ring 16 at the lower end of the inner shell 2. Moreover, the height of the positioning ring 16 at the lower end of the inner shell 2 is less than the height of the follower rod 15. This ensures that the vertical component of the tension applied by the pull rope 4 to the follower rod 15 is greater.

[0039] Similarly, in order to avoid rigid contact between the follower rod 15 and the core rod, the device also provides a contact pad II3 made of rubber on the outside of the follower rod 15, and the projection of the contact pad II3 on ​​the vertical plane at the end away from the inner wall of the inner shell 2 on the outside of the follower rod 15 is an arc-shaped structure, which can fully avoid scratching the core rod.

[0040] Furthermore, in order to facilitate the insertion of the core rod into the inner shell 2 and avoid the need for the operator to additionally adjust the position of the follower rod 15 during the initial core rod insertion process, the device is provided with a tension spring I5 at the upper end of each follower rod 15, and the two axial ends of the tension spring I5 are movably connected to the corresponding follower rod 15 and the inner wall of the inner shell 2 respectively. This is mainly to make the follower rod 15 have a tendency to rotate upward to shorten the projected length on the horizontal plane, thereby ensuring the smoothness of the initial core rod insertion.

[0041] It should be noted that, in the initial state, the tension spring I5 is not affected by external force, and the distance between the upper end surface of the follower rod 15 and the inner wall of the inner shell 2 is the smallest. At this time, the core rod is inserted, and at the same time, the positioning block 12 moves downward, and the pull rope 4 applies a downward pulling force to the follower rod 15, and the follower rod 15 rotates downward. At the same time, the tension spring I5 is stretched under the force.

[0042] Therefore, in order to ensure that the tension spring I5 can apply an upward pulling force to the follower rod 15 to make it rotate upward, the device constrains the angle between the central axis of the tension spring I5 and the horizontal plane to be greater than 30°.

[0043] At the same time, in order to ensure that the pull rope 4 can apply downward pulling force to the follower rod 15, in the initial state of the tension spring I5, the angle between the follower rod 15 and the inner wall of the inner shell 2 is greater than 20°.

[0044] Furthermore, in order to ensure that the pull rope 4 can pull the follower rod 15 to increase its projected length on the horizontal plane, the device is constrained in the initial state of the tension spring I5, and the angle between the follower rod 15 and the inner wall of the inner shell 2 is less than 80°.

[0045] It should be emphasized that if Figure 3As shown, in practice, the downward movement stroke of the follower rod 15 is limited, and the adjustment block can only abut against the upper end surface of the core rod when avoiding a large stroke movement. Therefore, in order to balance the relationship between the two, the present device divides the pull rope 4 into two sections, and the two sections of the pull rope 4 are rope body I 401 and rope body II 402 respectively. In addition, a tension spring II 14 is provided between rope body I 401 and rope body II 402, and the two axial ends of the tension spring II 14 are fixedly connected to the near ends of rope body I 401 and rope body II 402 respectively. This can not only adjust the relationship between the displacement distance of the positioning block 12 and the rotation amplitude of the follower rod 15, but also ensure that during the movement of the positioning block 12, rope body II 402 can apply sufficient downward pulling force to the follower rod 15, ensuring that the follower rod 15 is tightly fitted with the core rod, thereby fully ensuring the coaxiality between the present device and the core rod.

[0046] In actual use, the utility model:

[0047] First, the core rod is inserted into the inner housing 2. At this time, the tension spring I5 is not affected by external forces, and the contact pad II3 is not in contact with the core rod.

[0048] Then, the positioning nut 9 is rotated to move the positioning block 12 downward. During this process, the driven rod 11 moves downward, the tension spring II 14 extends, and the follower rod 15 rotates downward, so that the contact pad II 3 contacts the core rod;

[0049] Afterwards, as the positioning block 12 continues to move downward, the pressing force exerted by the contact pad II 3 on the core rod increases, and the device is slightly displaced so that the device and the core rod are coaxial;

[0050] Then, the positioning block 12 continues to move downward, and at the same time, the contact pad II 3 and the follower rod 15 stop rotating, and the tension spring II 14 stops extending. In addition, during this process, the tension spring II 14 continues to extend.

[0051] Finally, as the positioning block 12 continues to move downward until the contact pad I 13 contacts the core rod and is deformed by force, the device completes the assembly process on the core rod and begins the feeding operation.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
