Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to the feeding tube mechanism. Background Technology

[0002] Regarding the efficiency of processing or assembling tubular workpieces, most companies on the market have already shifted from manual to automated feeding of tubular workpieces. When feeding tubular workpieces to turntable mechanisms, it is often necessary to adjust their orientation. Commonly used feeding mechanisms such as robotic arms or other multi-directional displacement and rotation types have drawbacks such as high cost and need to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a tube-mounting mechanism, including a hopper for accommodating workpieces, a connecting seat, a tilting mechanism, a tube seat, and a telescopic mechanism. The tube seat has a groove for inserting the corresponding workpiece. The output end of the tilting mechanism is connected to the tube seat and rotates the tube seat in the longitudinal plane, causing the groove on the tube seat to switch back and forth between a transverse state and a longitudinal state. A connecting seat is provided between the tube seat and the outlet of the hopper, and a material channel is inclinedly provided on the connecting seat. The inlet of the material channel is connected to the outlet of the hopper, and the groove on the tube seat is located below the outlet of the material channel. The telescopic mechanism is located above the groove in the longitudinal state, and the moving end of the telescopic mechanism moves downward to push the workpiece out of the groove.

[0005] The hopper can hold multiple workpieces, and the feeding can be completed by adjusting the direction of the flipping mechanism in conjunction with the telescopic mechanism. The structure of the feeding mechanism is simplified and the cost is reduced.

[0006] Furthermore, it also includes a limiting mechanism, which includes a telescopic mechanism II and a baffle. The baffle is provided at the moving end of the telescopic mechanism II. The telescopic mechanism II moves the baffle longitudinally and reciprocates. The baffle moves down into the material channel to restrict the workpiece from moving down in the material channel. When the baffle moves up, it releases the restriction on the workpiece moving down along the material channel, improves the smoothness of operation, and prevents the workpiece from falling.

[0007] Furthermore, it also includes a fixed frame, on which a connecting seat, a telescopic mechanism one, and a telescopic mechanism two are provided for support and easy placement.

[0008] Furthermore, it also includes a pushing mechanism, which comprises a drive mechanism, a connecting shaft, a connecting column, a connecting plate, and a fixed shaft. The output end of the drive mechanism is connected to the connecting shaft, and a connecting column is radially arranged on the connecting shaft. The end of the connecting column is hinged to a waist hole formed at the connecting plate. The connecting plate is connected to the fixed shaft at one side of the hinge point of the connecting column. The fixed shaft is hinged to the connecting seat and is located above the material channel. A push plate is provided at the fixed shaft. When the connecting shaft, connecting column, and connecting plate rotate, the drive mechanism drives the fixed shaft to rotate. During the downward rotation of the push plate, the workpiece in the material channel is pushed forward. The push plate helps to reduce the phenomenon of workpiece jamming and improves the smoothness of operation.

[0009] Furthermore, it also includes a guide frame, which includes longitudinally extending support rods and laterally extending support rods. The two longitudinally extending support rods are connected by the laterally extending support rods. The laterally extending support rods are fixed to the connecting seat. The space between the longitudinally extending support rods and the bottom wall of the material channel allows for the sliding of a single workpiece in the longitudinal direction. The guide frame restricts the movement of multiple workpieces in the longitudinal direction, reducing the phenomenon of multiple workpieces moving forward in a superimposed manner and improving the smoothness of operation.

[0010] Furthermore, it also includes a baffle plate and a handle. The baffle plate is slidably connected to a groove formed above the hopper outlet. The end of the handle is threaded to the wall of the groove. The baffle plate moves down to block the hopper outlet. The handle is rotated so that its end moves forward to abut against the baffle plate and fix it in the desired position. The baffle plate can be moved down and the handle can be rotated to lock it as needed, restricting the workpiece in the hopper from being discharged from the outlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The structure of the upper tube mechanism designed in this utility model is such that the hopper pre-stores workpieces such as hoses, the tube seat cooperates with the flipping mechanism to adjust the orientation of the hoses, and the telescopic mechanism presses down to complete the feeding of the turntable mechanism. The whole structure is simplified and helps to reduce costs. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 As shown, in this example, the upper tube assembly includes a hopper 40 for accommodating workpieces, a connecting seat 47, a tilting mechanism 52, a tube seat 42, and a telescopic mechanism 44. The tube seat 42 has a groove 43 formed for inserting a flexible tube. The output end of the tilting mechanism 52 is connected to the tube seat 42 and rotates the tube seat 42 in the longitudinal plane. Preferably, a fixing block 45 is installed at the output end of the tilting mechanism 52, and the tube seat 42 is installed on the fixing block 45 for easy docking and adjustment of the tube seat's position. The fixing block 45 is L-shaped, fixing the tube seat 42 in its longitudinal portion and fixing its transverse portion to the output end of the tilting mechanism 52. The tilting mechanism 52 is like a tilting cylinder, causing the groove 43 on the tube seat 42 to reciprocate between a transverse and longitudinal state.

[0021] A connecting seat 47 is installed between the tube seat 42 and the outlet of the hopper 40, and an inclined extending channel 471 is formed on the connecting seat 47. The inlet of the channel 471 is connected to the outlet of the hopper 401. The groove 43 on the tube seat 42 is located below the outlet of the channel 471. The telescopic mechanism 44 is located above the groove 43 in the longitudinal state. The moving end of the telescopic mechanism 44 moves down to push the hose in the groove 43 to the lower cup seat.

[0022] To facilitate the fixing of the connecting seat and other mechanisms, a fixing frame 51 is added in this example. The fixing frame 51 is fixed to the base 42, and the connecting seat 47 is fixed on the fixing frame 51. The hopper 471 is fixed to the fixing frame 51 or the connecting seat. The flipping mechanism 52 is fixed at the fixing frame 51 below the connecting seat 47. The telescopic mechanism 44 is connected to the fixing frame 51 and is located on the side of the connecting seat 47.

[0023] In use, tilting the hopper or tilting the bottom wall of the hopper cavity allows the hose in the hopper to slide more easily to the hopper outlet. The hopper can hold multiple hoses, which slide out through the hopper outlet 401 into the feed channel and then slide down the feed channel. The flipping mechanism rotates the tube seat so that its groove is in a horizontal position (lateral state). The hose sliding out of the feed channel enters the horizontal groove. Then, the flipping mechanism rotates the tube seat so that the groove changes from horizontal to vertical (longitudinal state). At this time, the moving end of the telescopic mechanism is above the groove. The moving end of the telescopic mechanism moves downward to push the hose in the groove into the cup seat cavity. Preferably, a pressure block or pressure plate is placed at the moving end of the telescopic mechanism to better press down the hose.

[0024] In addition, a limiting mechanism can be added, which includes a telescopic mechanism 50 and a baffle 49. The telescopic mechanism 50 is like a telescopic cylinder, which is connected to the connecting seat 47 and located above the material outlet. The baffle 49 is fixed at the moving end of the telescopic mechanism 50. When in use, if the telescopic mechanism 50 moves the baffle 49 longitudinally, the baffle 49 moves down into the material channel to limit the downward movement of the hose in the material channel. If the baffle moves up, the restriction on the downward movement of the hose along the material channel is released.

[0025] A pushing mechanism 41 can also be added. The pushing mechanism 41 includes a drive mechanism 410, a connecting shaft, a connecting column 414, a connecting plate 413, and a fixed shaft 411. The drive mechanism is such as a drive motor, and its output end is connected to the connecting shaft. The axial center lines of the two are on the same straight line. The connecting column 414 is fixed radially at the other end of the connecting shaft. The top end of the connecting column 414 is hinged to a waist hole formed in the connecting plate 413. The connecting plate 413 is fixed to the fixed shaft 411 at one side of the hinge point between the connecting column 414 and the connecting plate 413. The fixed shaft 411 is hinged to the connecting seat 47 and is located above the material channel. A push plate 412 is fixed on the fixed shaft 411. The push plate is such as a flat plate or... Figure 1 , Figure 2 The tank shape shown.

[0026] In use, the drive mechanism rotates the connecting shaft, which in turn drives the connecting column to rotate. The connecting column pulls the connecting plate to rotate downwards, simultaneously driving the fixed shaft to rotate. As the push plate rotates downwards, it pushes the flexible hose in the material channel forward, which helps to improve the smoothness and stability of feeding.

[0027] A guide frame can also be added, which may include longitudinally extending rods 48 and laterally extending rods 48. The two longitudinally extending rods 48 are connected by the laterally extending rods 48, and the laterally extending rods 48 are fixed to the connecting seat 47. The space between the longitudinally extending rods and the bottom wall of the material channel 471 allows a single hose to slide, preventing multiple hoses from overlapping and improving the smoothness of operation. In addition, the ends of the longitudinally extending rods at the hopper outlet can be upturned, forming a flared configuration, to facilitate the entry of hoses into the space between the longitudinally extending rods and the bottom wall of the material channel cavity.

[0028] An insert plate 402 and a handle can also be added. The insert plate is slidably connected to a groove formed above the hopper outlet. The end of the handle 403 is threaded to the groove wall. When the insert plate moves down, it blocks the hopper outlet. The handle can be rotated so that its end abuts against the insert plate to fix it. During maintenance or shutdown, the insert plate can be moved down to block the outlet. Then, the handle can be rotated so that its end moves forward to abut against the insert plate, thereby fixing it.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
