Description

Technical Field

[0001] The utility model relates to the technical field of pipes, and more specifically, to a pipe feeding device for pipes. Background Art

[0002] Currently, the mechanism commonly used for transporting plastic pipes is to directly lift and push with an oil cylinder (or air cylinder), or to press on the surface of the pipe and make the pipe move forward by the rotation friction of the wheel. During the process of injection molding pipe joints, due to the excessive length and weight of the pipe, when the movement of transporting the pipe stops, due to inertia, the pipe has a tendency to move forward, resulting in a deviation between the position of the pipe and the position required for production. In view of this, a pipe feeding device that can accurately change the position of the pipe is needed. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a pipe feeding device for pipes, which can clamp the pipe to prevent the movement direction or stop position of the pipe from shifting.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is:

[0005] Provide a pipe feeding device for pipes, including a chassis, a second fixing plate, a telescopic assembly, two groups of clamping members, and a moving assembly for moving the second fixing plate. The moving assembly is installed on the chassis, the second fixing plate is connected to the moving assembly, the clamping members are slidably installed on the second fixing plate, one end of the telescopic assembly is fixed on the second fixing plate, and the other end is fixedly connected to the clamping members. The telescopic direction of the telescopic assembly is the same as the sliding direction of the clamping members, and the opposite sides of the two groups of clamping members can be attached to the pipe.

[0006] For the pipe feeding device of the utility model, the pipe is moved between the two groups of clamping members, the telescopic assembly extends, so that the two groups of clamping members move towards each other to clamp the pipe. The moving assembly installed on the chassis drives the second fixing plate to move, thereby driving the pipe to move, so that the pipe can be accurately moved to a predetermined position, and there will be no deviation during the movement process, and it will stop immediately with the clamping members when the movement stops, and will not continue to move due to inertia; the two groups of clamping members are slidably connected to the second fixing plate, and under the action of the telescopic assembly, the pipe is clamped horizontally. The relative height of the clamping members with respect to the second fixing plate and the moving assembly is fixed, so that the clamping members can independently support the pipe, and the relative position of the pipe in the vertical direction with respect to the moving assembly remains unchanged.

[0007] Furthermore, a third guide rail is fixed on the second fixing plate, a third slider is fixed on the clamping member, and the third slider is slidably installed on the third guide rail. Through the cooperation of the third slider and the third guide rail, the clamping member can only move along the third guide rail without deviation, making the clamping process of the clamping member more stable.

[0008] Further, the clamping member includes a clamping base and a detachable clamping block. The third slider is fixed on the clamping base. The clamping blocks are mounted on the opposite side surfaces of two groups of clamping bases. The longitudinal section of the clamping block is arc-shaped. Multiple clamping blocks of different specifications are nested and connected in sequence. From the clamping block fixedly connected to the clamping base to the clamping block in contact with the pipe, the diameter gradually decreases. By disassembling or installing the clamping blocks and changing the number of clamping blocks, the specifications of the clamping member can be simply adjusted, so as to clamp pipes of different specifications more stably. When clamping a pipe, according to the specification of the pipe, adjust the number of clamping blocks so that the clamping blocks in contact with the pipe can be closely attached to the pipe. Move the pipe to a suitable installation position. The telescopic assembly pushes the clamping base to slide on the second fixing plate, and the clamping base drives the clamping blocks to move towards each other to clamp and fix the pipe.

[0009] Further, there are two groups of telescopic assemblies, and the telescopic directions of the two groups of telescopic assemblies are opposite. The telescopic assembly includes a first cylinder and a first cylinder mounting plate. The first cylinder mounting plate is vertically fixed on the second fixing plate. The first cylinder is fixedly installed on the first cylinder mounting plate. The output end of the first cylinder passes through the first cylinder mounting plate and is fixedly connected to the clamping member. When the output end of the first cylinder extends, the two groups of clamping members move away from the first cylinder mounting plate, so as to realize the relative movement of the two groups of clamping members.

[0010] Further, a first guide rail is horizontally arranged on the side surface of the chassis. A first slider is arranged on the second fixing plate. The first slider is slidably installed in the first guide rail. The moving direction of the moving assembly is the same as the direction of the first guide rail. The first slider is slidably installed in the first guide rail, so that the second fixing plate can only move along the first guide rail, improving the stability of the pipe movement.

[0011] Further, it further includes a pipe supporting component for supporting the pipe. The pipe supporting component is fixed on the chassis. Before clamping the pipe, place the pipe on the pipe supporting component. It is not necessary to maintain the position of the pipe manually before the pipe is clamped, making the clamping process more convenient and labor-saving.

[0012] Further, at least two groups of pipe supporting components are provided. The pipe supporting component includes a first fixing plate, a lifting mechanism and a supporting member for supporting the pipe. The supporting member is connected to the first fixing plate through the lifting mechanism. The first fixing plate is fixed on the chassis. When using the device, place the pipe on the supporting member, turn on the lifting mechanism, and adjust the height of the supporting member and the pipe until the pipe reaches a suitable fixing position. Setting at least two groups of pipe supporting components can improve the balance and stability of the pipe supporting component when supporting the pipe.

[0013] Further, the lifting mechanism includes a first lifting component, a second lifting component and a connecting plate. A second guide rail is provided on the connecting plate, and a second slider is provided on the first fixing plate. The second slider is slidably installed in the second guide rail. The first lifting component is connected between the first fixing plate and the connecting plate, and the second lifting component is connected between the connecting plate and the support member. Place the pipe on the support member. The first lifting component lifts the pipe to a height close to the pipe clamping component. Start the second lifting component to adjust the height of the support member and the pipe so that the pipe reaches a suitable fixing position. After the clamping block clamps the pipe, the second lifting component drops to separate the support member from the pipe.

[0014] Further, the support member includes a supporting wheel and a supporting wheel fixing seat. The supporting wheel is rotatably installed on the supporting wheel fixing seat. The rotation axis direction of the supporting wheel is horizontal, and the diameter of the cross section of the supporting wheel perpendicular to its axis gradually decreases from both ends to the middle of the axis. When placing the pipe, first place one end of the pipe at the lowest point of the supporting wheel, and push the pipe to move in a direction perpendicular to the axis of the supporting wheel until multiple groups of supporting wheels stably support the pipe. When the pipe slides relative to the supporting wheel, the supporting wheel can convert sliding friction into rolling friction, reduce the friction force on the pipe and avoid damage to the pipe. It is more labor-saving when placing the pipe. The diameters of both ends of the supporting wheel are large and the diameter in the middle is small, which can better support the pipe, prevent the pipe from slipping from both sides, and at the same time play a guiding role for the pipe.

[0015] Further, the moving component includes a first motor, a main sprocket, a slave sprocket and a transmission chain. A set of the main sprocket and the slave sprocket are rotatably installed on the same side edge of the chassis. The first motor is installed on the chassis, and the output end of the first motor is fixedly connected to the axis of the main sprocket. The main sprocket and the slave sprocket are sleeved inside the transmission chain and meshed with the transmission chain. The second fixing plate is fixedly connected to the transmission chain. When moving the pipe, start the first motor. The first motor drives the main sprocket to rotate, drives the slave sprocket and the transmission chain to rotate, so that the second fixing plate fixedly connected to the transmission chain moves along the transmission chain, driving the pipe to move.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] Through the opposite movement of the two clamping members, the pipe is clamped horizontally. Only two clamping members are needed to firmly fix the pipe, and the pipe can be accurately moved to a predetermined position without deviation due to inertia. Moreover, the relative position in the vertical direction with the moving component remains fixed and does not require other components for auxiliary fixation. The structure is simple and the operation is convenient. Description of the Drawings

[0026] Embodiment 1

[0027] As Figures 1 to 5 Shown in FIG. 1 is Embodiment 1 of the pipe feeding device of the present utility model. A pipe feeding device is provided, which includes a chassis 1, a second fixing plate 21, a telescopic assembly 23, two groups of clamping members 22, and a moving assembly 4 for moving the second fixing plate 21. The moving assembly 4 is installed on the chassis 1. The second fixing plate 21 is connected to the moving assembly 4. The clamping members 22 are slidably installed on the second fixing plate 21. One end of the telescopic assembly 23 is fixed on the second fixing plate 21, and the other end is fixedly connected to the clamping members 22. The telescopic direction of the telescopic assembly 23 is the same as the sliding direction of the clamping members 22. The opposite sides of the two groups of clamping members 22 can be attached to the pipe 5.

[0028] For the pipe feeding device of the present utility model, the pipe 5 is extended between the two groups of clamping members 22. The telescopic assembly 23 extends, causing the two groups of clamping members 22 to move relative to each other to clamp the pipe 5. The moving assembly 4 installed on the chassis 1 drives the second fixing plate 21 to move, thereby driving the pipe 5 to move, enabling the pipe 5 to be accurately moved to a predetermined position without deviation during the movement process and immediately stopping with the clamping members 22 when the movement stops without continuing to move due to inertia. The two groups of clamping members 22 are slidably connected to the second fixing plate 21, and under the action of the telescopic assembly 23, the pipe 5 is clamped transversely. The relative height of the clamping members 22 with respect to the second fixing plate 21 and the moving assembly 4 is fixed, enabling the clamping members 22 to independently support the pipe 5, keeping the relative position of the pipe 5 in the vertical direction unchanged with respect to the moving assembly 4 without the need for other components to assist in fixing, with a simple structure and convenient operation.

[0029] A third guide rail 212 is fixed on the second fixing plate 21, and a third slider 221 is fixed on the clamping member 22. The third slider 221 is slidably installed on the third guide rail 212. Through the cooperation of the third slider 221 and the third guide rail 212, the clamping member 22 can only move along the third guide rail 212 without deviation, making the clamping process of the clamping member 22 more stable. As Figure 2 shown.

[0030] The clamping member 22 includes a clamping seat 221 and a detachable clamping block 222. The third slider 2211 is fixed on the clamping seat 221. The clamping block 222 is installed on the opposite side surfaces of two groups of clamping seats 221. The longitudinal section of the clamping block 222 is arc-shaped. Multiple clamping blocks 222 of different specifications are nested and connected in sequence. From the clamping block 222 fixedly connected to the clamping seat 221 to the clamping block 222 in contact with the pipe 5, the diameter gradually decreases. By disassembling or installing the clamping block 222 and changing the number of layers of the clamping block 222, the specifications of the clamping member 22 can be simply adjusted, so as to more stably clamp pipes 5 of different specifications. When clamping the pipe 5, according to the specifications of the pipe 5, the number of clamping blocks 222 is adjusted so that the clamping blocks 222 in contact with the pipe 5 can closely fit the pipe 5. The pipe 5 is moved to a suitable installation position, and the telescopic assembly 23 pushes the clamping seat 221 to slide on the second fixing plate 21. The clamping seat 221 drives the clamping blocks 222 to move towards each other to clamp and fix the pipe 5. The combination of the second fixing plate 21, the telescopic assembly 23, the clamping seat 221 and the clamping block 222 is denoted as the pipe clamping assembly 2.

[0031] In this embodiment, the pipe feeding device of the pipe further includes a controller. The pipe supporting assembly 3, the pipe clamping assembly 2 and the moving assembly 4 are all connected to the controller.

[0032] The telescopic assembly 23 that can push the clamping seat 221 to slide in the opposite direction, such as an electric push rod structure, a cylinder structure, etc., can all be applied to the present invention. The telescopic assembly listed in this embodiment is not a limitation of the present invention.

[0033] In this embodiment, there are two groups of telescopic assemblies 23. The telescopic directions of the two groups of telescopic assemblies 23 are opposite. The telescopic assembly 23 includes a first cylinder 231 and a first cylinder mounting plate 232. The first cylinder mounting plate 232 is vertically fixed on the second fixing plate 21. The first cylinder 231 is fixedly installed on the first cylinder mounting plate 232. The output end of the first cylinder 231 passes through the first cylinder mounting plate 232 and is fixedly connected to the back surface of the clamping member 22. When the output end of the first cylinder 231 extends, the two groups of clamping members 22 move in a direction away from the first cylinder mounting plate 232, so as to realize the opposite movement of the two groups of clamping members 22.

[0034] The first cylinder 231 has a compact structure, light weight and small occupied space. A rib plate 24 is provided between the first cylinder mounting plate 232 and the second fixing plate 21 to enhance the structural strength of the device.

[0035] A first guide rail 11 is horizontally arranged on the side of the chassis 1. A first slider 211 is provided on the second fixed plate 21. The first slider 211 is slidably installed in the first guide rail 11. The moving direction of the moving assembly 4 is the same as the direction of the first guide rail 11. The first slider 211 is slidably installed in the first guide rail 11, enabling the second fixed plate 21 to only move along the first guide rail 11, improving the stability of the movement of the pipe 5.

[0036] Limit plates 12 are provided at both ends of the chassis 1. Limit rubber blocks 13 are provided on the limit plates 12. The limit plates 12 and the limit rubber blocks 13 can limit the horizontal movement of the second fixed plate 21 and reduce the impact when it reaches the limit position, prevent the second fixed plate 21 from being damaged, extend the service life of the device, and at the same time avoid the pipe 5 from having a position deviation or even falling off due to excessive impact.

[0037] The moving assembly 4 includes a main sprocket 42, a slave sprocket 43, and a transmission chain 44. A set of the main sprocket 42 and the slave sprocket 43 are rotatably installed on the same side of the chassis 1. A first motor 41 is installed on the chassis 1. The output end of the first motor 41 is fixedly connected to the axis of the main sprocket 42. The main sprocket 42 and the slave sprocket 43 are sleeved inside the transmission chain 44 and meshed with the transmission chain 44. The second fixed plate 21 is fixedly connected to the transmission chain 44. When moving the pipe 5, the first motor 41 is started. The first motor 41 drives the main sprocket 42 to rotate, driving the slave sprocket 43 and the transmission chain 44 to rotate, so that the second fixed plate 21 fixedly connected to the transmission chain 44 moves along the transmission chain 44, driving the pipe 5 to move. The movement of the pipe 5 is realized by means of chain drive, with high efficiency and strong reliability, and can be applicable to diverse working environments.

[0038] There are two sets of the moving assembly 4, which are respectively arranged on both sides of the chassis 1. Two first sliders 211 are provided at the bottom of the pipe clamping assembly 2. The two first sliders 211 are respectively slidably installed in the two sets of first guide rails 11. As Figure 5 shown.

[0039] Embodiment 2

[0040] This embodiment is the second embodiment of the present utility model. This embodiment is similar to Embodiment 1. The difference lies in that it further includes a pipe supporting assembly 3 for supporting the pipe 5. The pipe supporting assembly 3 is fixed on the chassis 1. Before clamping the pipe 5, the pipe 5 is placed on the pipe supporting assembly 3, and there is no need to manually maintain the position of the pipe 5 unchanged before the pipe 5 is clamped, making the clamping process more convenient and labor-saving.

[0041] At least two sets of the hosting components 3 are provided. The hosting component 3 includes a first fixing plate 31, a lifting mechanism 33, and a support member 34 for supporting the pipe 5. The support member 34 is connected to the first fixing plate 31 through the lifting mechanism 33, and the first fixing plate 31 is fixed on the chassis 1. When using the device, place the pipe 5 on the support member 34, turn on the lifting mechanism 33, and adjust the heights of the support member 34 and the pipe 5 until the pipe 5 reaches a suitable fixing position. Setting at least two sets of hosting components 3 can improve the balance and stability when the hosting components 3 lift the pipe 5. In this embodiment, at least three sets of hosting components 3 are provided. Setting three sets of hosting components 3 can further improve the balance and stability when the hosting components 3 lift the pipe 5.

[0042] The support member 34 includes a supporting wheel 341 and a supporting wheel 341 fixing seat. The supporting wheel 341 is rotatably installed on the supporting wheel 341 fixing seat. The rotation axis direction of the supporting wheel 341 is horizontal, and the cross-sectional diameter of the supporting wheel 341 perpendicular to its axis gradually decreases from both ends to the middle of the axis.

[0043] In this embodiment, a rotating shaft seat with a horizontal axis direction is provided on the supporting wheel fixing seat 342, and the supporting wheel 341 is rotatably installed on the rotating shaft seat. As Figure 3 shown.

[0044] When placing the pipe 5, first place one end of the pipe 5 at the lowest point of the supporting wheel 341, and push the pipe 5 to move in a direction perpendicular to the axis of the supporting wheel 341 until multiple sets of supporting wheels 341 stably support the pipe 5. In this embodiment, that is, the pipe 5 is supported by three sets of supporting wheels 341. When the pipe 5 slides on the supporting wheel 341, the supporting wheel 341 can convert sliding friction into rolling friction, reduce the friction force on the pipe 5, and avoid damage to the pipe 5. It is more labor-saving when placing the pipe 5. The diameters of both ends of the supporting wheel 341 are large, and the diameter in the middle is small, which can better support the pipe 5, prevent the pipe 5 from slipping off from both sides, and at the same time play a guiding role for the pipe 5.

[0045] Embodiment Three

[0046] This embodiment is the third embodiment of the present utility model. This embodiment is similar to Embodiment 1, except that the lifting mechanism 33 includes a first lifting component 331, a second lifting component 332, and a connecting plate 32. A second guide rail 321 is provided on the connecting plate 32, and a second slider 311 is provided on the first fixing plate 31. The second slider 311 is slidably installed in the second guide rail 321. The first lifting component 331 is connected between the first fixing plate 31 and the connecting plate 32, and the second lifting component 332 is connected between the connecting plate 32 and the support member 34. Place the pipe 5 on the support member 34. The first lifting component 331 lifts the pipe 5 to a height close to the pipe clamping component 2. Start the second lifting component 332 to lift the support member 34 and the pipe 5 so that the pipe 5 reaches a suitable fixing position. After the clamping block 222 clamps the pipe 5, the second lifting component 332 falls back to separate the support member 34 from the pipe 5, reducing the resistance suffered by the pipe 5 during movement.

[0047] The first lifting component 331 includes a second motor 3311, a lead screw 3312, and a nut 3313. The second motor 3311 is installed on the first fixing plate 31. Vertically arranged bearing fixing seats 3314 and bearing support seats 3315 are provided on the connecting plate 32. The lead screw 3312 is rotatably connected between the bearing fixing seat 3314 and the bearing support seat 3315. The output end of the second motor 3311 is fixedly connected to the end of the lead screw 3312. The nut 3313 is fixed on the first fixing plate 31, and the internal thread of the nut 3313 cooperates with the external thread of the lead screw 3312. When controlling the lifting of the pipe 5, control the start of the three groups of second motors 3311 to synchronously drive the rotation of the lead screw 3312. Since the position of the lead screw 3312 is restricted between the bearing fixing seat 3314 and the bearing support seat 3315, and the nut 3313 is fixed on the fixing plate, the lead screw 3312 moves axially under the action of the thread, driving the connecting plate 32 to move up and down to move the pipe 5 to a suitable position. The second motor is a servo motor. As Figure 3 shown.

[0048] The second lifting assembly 332 includes a second cylinder mounting plate 3322, a second cylinder 3321, two sets of slide rods 3323, two sets of limit sleeves 3324, and a movable plate 3325. The second cylinder mounting plate 3322 is fixed to the connecting plate 32. The second cylinder 3321 is fixedly installed on the second cylinder mounting plate 3322. The support member 34 is installed on the top of the movable plate 3325. A connecting column is fixed to the bottom of the movable plate 3325. The movable plate 3325 is fixedly connected to the output end of the second cylinder 3321 through the connecting column. The slide rods 3323 are fixedly connected to the bottom of the movable plate 3325. The limit sleeves 3324 are fixed to the second cylinder mounting plate 3322. The two sets of limit sleeves 3324 are symmetrically distributed on both sides of the second cylinder 3321. The slide rods 3323 extend into the limit sleeves 3324. The limit sleeves 3324 can limit the horizontal position of the slide rods 3323, thereby limiting the horizontal position of the movable plate 3325 and making the lifting of the movable plate 3325 and the support member 34 more stable. As Figure 4 shown.

[0049] By providing two lifting assemblies, the requirement for the maximum stroke of each lifting assembly can be reduced.

[0050] In this embodiment, the pipe feeding device further includes a controller. The pipe holding assembly 2, the pipe supporting assembly 3, and the moving assembly 4 are all connected to the controller. When the pipe feeding device works, the controller controls the second motors 3311 of the three sets of pipe supporting assemblies 3 to rotate synchronously, drives the lead screws 3312 to rotate, so that the pipe 5 is lifted to a suitable installation position while keeping horizontal. The controller controls the first cylinder 231 to push the clamping seats 221 to move towards each other, so that the clamping blocks 222 clamp the pipe 5, and then controls the moving assembly 4 to transport the pipe 5 to the target position.

[0051] In the specific content of the above specific implementation manner, the technical features can be combined arbitrarily without contradiction. For the sake of brief description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should be considered as the scope recorded in this specification.

[0052] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description.
