Description

Technical Field

[0001] The invention relates to the technical field of down production and processing, in particular to an auxiliary loading rack for down production and processing. Background Art

[0002] Down is the reed-shaped down that grows on the abdomen of geese and ducks. Because down is an animal protein fiber, it can absorb the flowing heat emitted by people and isolate the invasion of cold air from the outside. In terms of fluffiness, down is one level higher than silk, cotton and other thermal insulation materials. For example, the lowest standard 450-degree fluffiness 90 down is also better than silk and cotton. Therefore, as a thermal insulation material, the economic value of down is far higher than other thermal insulation materials.

[0003] Down production and processing generally includes rough sorting, ash removal, cleaning, drying, cooling, fine sorting, and packaging. In the traditional down packaging process, the mouth of the packaging bag is manually put on the outlet of the material pipe to prevent the down from overflowing during filling; however, this requires workers to stay at the outlet of the material pipe all the time, which not only increases the workload, but also causes long-term contact with the down, which can easily lead to the down being inhaled into the lungs, affecting the safety of the workers. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an auxiliary loading rack for down production and processing.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

A driving device is arranged on the platform for driving the clamping device to tighten the bag opening to the outlet pipe opening under the guidance of the track plate and to preliminarily close the bag opening after loading is completed. The driving devices are connected by a pulley assembly, and any one of the driving devices is connected to a servo motor.

[0007] Furthermore, the clamping device includes a horizontal sleeve and a pneumatic gripper horizontally distributed between the symmetrical track plates, the horizontal sleeve is connected to the driving device, and the pneumatic gripper is horizontally slidable in the horizontal sleeve and slidably connected to the track plate.

[0008] Furthermore, open sliding grooves distributed in the horizontal direction are symmetrically arranged on the two side walls corresponding to the horizontal sleeve, and the pneumatic clamp is provided with a track rod passing through the open sliding groove and slidingly cooperating with the track plate.

[0009] Furthermore, the track plate is provided with a track groove for providing track guidance for the track rod, and the track groove is composed of a No. 1 arc groove, a No. 1 straight groove, a No. 2 straight groove, and a No. 2 arc groove connected end to end in sequence.

[0010] Furthermore, the driving device includes a screw rod and a guide rod vertically arranged on the platform and connected to the clamping device, and the lower end of the screw rod is connected to the pulley assembly.

[0011] The beneficial effects of the present invention are:

[0012] The present invention provides a track plate and a driving device, so that a plurality of pneumatic grippers on a polygonal support frame can realize a movement process of synchronously clamping the mouth of a packaging bag to the mouth of a discharge pipe and preliminarily closing the mouth of the bag after loading is completed; it replaces the manual clamping of the mouth of the packaging bag to clamp the mouth of the discharge pipe, reduces the labor intensity of workers, avoids long-term contact between workers and down, and ensures the life safety of workers.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown, an auxiliary loading rack for down production and processing includes a hexagonal support frame 1, which is composed of six support columns evenly distributed around the circumference and a connecting frame plate connecting adjacent support columns. A support plate 2 for placing packaging bags is provided at the lower middle part of the hexagonal support frame 1, and the four sides of the support plate 2 are connected to the six support columns and the connecting frame plate through reinforcing connecting plates; the upper end of each support column in the hexagonal support frame 1 is provided with a horizontal rectangular stand 3 placed in the radial direction. Each stand 3 is provided with two track plates 6 symmetrically distributed front and back, and a clamping device distributed between the two track plates 6 and slidably connected thereto. Each stand 3 is also provided with a driving device for driving the clamping device to clamp the bag opening to the outlet pipe opening under the guidance of the track of the track plate and to preliminarily close the bag opening after the loading is completed. Each driving device is connected by a pulley assembly, and the pulley assembly includes a pulley 9 provided on the driving device and a belt 10 connecting the six pulleys 9; a servo motor 11 is installed at the bottom of the stand 3 on the leftmost side of the hexagonal support frame 1 through a mounting plate frame 111. Through the pulley assembly, the above six driving devices can synchronously drive the corresponding connected clamping devices to move.

[0020] like Figure 4 As shown, the clamping device includes a horizontal sleeve 4 and a pneumatic gripper 5 horizontally distributed between two track plates 6. The pneumatic gripper 5 is horizontally slidable in the horizontal sleeve 4 through a slide rod 51 arranged at the left end. The left end of the horizontal sleeve 4 is connected to the driving device. The front and rear side walls of the horizontal sleeve 4 are symmetrically provided with open slide grooves 4a distributed in the horizontal direction and opening to the right. The front and rear sides of the slide rod 51 are correspondingly provided with track rods 12 that pass through the open slide grooves 4a and are slidably connected to the track plate 6.

[0021] The track plate 6 is provided with a track groove matched with the track rod 12, and the track groove is composed of a first arc groove 13, a first straight groove 14, a second straight groove 15, and a second arc groove 16 connected end to end.

[0022] Specifically, the No. 1 arc groove 13 is used to provide an arc-shaped rising guide for the pneumatic gripper 5; the connection point between the No. 1 arc groove 13 and the No. 1 straight groove 14 is the highest point, which is also the highest rising position of the horizontal sleeve 4. When the driving device drives the horizontal sleeve 4 to rise to this point, the servo motor 11 will stop working, and when the pneumatic gripper 5 moves to this point, the packaging bag mouth clamped by each pneumatic gripper 5 just tightens the outlet pipe mouth to prevent the down from flying out during the loading process, causing environmental pollution and waste.

[0023] The No. 1 linear groove 14 is used to provide a guide for the pneumatic gripper 5 to descend vertically. When the pneumatic gripper 5 moves to the connecting point of the No. 1 linear groove 14 and the No. 2 linear groove 15 , the pneumatic gripper 5 is separated from the outlet of the material discharge pipe.

[0024] The No. 2 linear groove 15 is used to provide the pneumatic gripper 5 with an inclined guide toward the inner side and the lower side. During the sliding process of the pneumatic gripper 5 in the No. 2 linear groove 15, the pneumatic gripper 5 gradually closes radially inward while continuing to descend. When the pneumatic gripper 5 moves to the connection point between the No. 2 linear groove 15 and the No. 2 arc groove 16, the mouth of the packaging bag clamped by the pneumatic gripper 5 is initially closed. The purpose of the initial closing of the packaging bag is to facilitate subsequent workers to seal the bag and further reduce the labor intensity of the workers.

[0025] The second arc groove 16 is used to provide a reset guide for the pneumatic gripper 5. After completing the initial closing of the packaging bag mouth, the pneumatic gripper 5 releases the grip on the packaging bag mouth, and as the horizontal sleeve 4 continues to descend, the pneumatic gripper 5 gradually resets into the horizontal sleeve 4 along the arc trajectory of the second arc groove 16.

[0026] The driving device includes a screw rod 7 and a guide rod 8 which are vertically arranged on the platform 3 through a bearing seat and connected to the horizontal sleeve 4. The left end of the horizontal sleeve 4 is installed with a screw slider 41 through a screw, and the screw slider 41 is installed on the screw rod 7. The guide rod 8 is symmetrically distributed on the left side of the horizontal sleeve 4. The lower end of the screw rod 7 extends to the bottom of the platform 3, and the pulley 9 is coaxially installed on the lower end of the screw rod 7.

[0027] Usage process:

[0028] Initially, the pneumatic gripper 5 on the loading auxiliary frame is at the position where the first arc groove 13 and the second arc groove 16 are connected, which is the starting position. The slide rod 51 is completely in the horizontal sleeve 4, and the horizontal sleeve 4 is at the lowest point of the screw rod 7.

[0029] When in use, place the packaging bag on the carrier plate 2 and place the packaging bag directly below the outlet of the material discharging pipe. The six pneumatic grippers 5 are respectively clamped on the bag opening of the packaging bag, and the servo motor 11 is started. The screw rod 7 drives the horizontal sleeve 4 and the pneumatic gripper 5 to rise at a constant speed, wherein the pneumatic gripper 5 passes through the track rod 12 on the slide bar 51, and under the track guidance of the first arc groove 13, the pneumatic gripper 5 drives the packaging bag opening to clamp the outlet of the material discharging pipe. At this time, turn off the servo motor 11, and the outlet of the material discharging pipe can be discharged after being clamped. After the loading is completed; the servo motor 11 drives the screw rod 7 to reverse, and the horizontal sleeve 4 descends at a constant speed. wherein the pneumatic gripper 5 drives the packaging bag opening to initially close and then release the packaging bag opening under the track guidance of the first linear groove 14, the second linear groove 15, and the second arc groove 16, and resets to the starting position, waiting for the next packaging bag to be loaded.
