Description

Technical Field

[0001] This invention relates to the field of fixing agent barrel production, and more particularly to a processing device for fixing agent barrels after blow molding. Background Technology

[0002] Color-fixing agents are common chemical preparations in the clothing industry, widely used to prevent dyed clothes from fading. These chemicals are typically contained in specialized, corrosion-resistant chemical drums. However, these drums are not ready to use immediately after blow molding; several issues need to be addressed. First, the bottom of the blow-molded drum has a layer of plastic film formed during the process, which needs to be cut off. Second, the opening of the drum expands slightly due to the high temperature, making it slightly larger than the final shape. Therefore, workers need to forcefully close the lid to allow it to set for a period before opening. Currently, we use a semi-automatic process: after demolding, workers send the drum to a cutting tool for cutting, and then forcefully close the lid. This process has relatively low production efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a processing device for the blow-molded fixing agent barrel, including a rotating processing table with multiple processing stations arranged in a circular array around its perimeter. The rotating processing table rotates, and the fixing agent barrel passes through each processing station sequentially. The upper edge of the rotating processing table is sequentially provided with a fixing agent barrel feeding station, a first reserved station, a fixing agent barrel opening plastic cutting station, a fixing agent barrel opening grinding station, a fixing agent barrel opening shaping station, a second reserved station, and a fixing agent barrel discharge station. The color-fixing agent barrel opening plastic cutting station is equipped with a cutting blade that extends into the barrel opening for rotary cutting; the color-fixing agent barrel opening grinding station is equipped with a grinding head that extends into the barrel opening for grinding the plastic burrs generated when cutting off excess plastic at the color-fixing agent barrel opening plastic cutting station; the color-fixing agent barrel opening shaping station is equipped with a shaping barrel lid feeding device, and a pressing plate is installed above the color-fixing agent barrel opening shaping station to press the shaping barrel lid onto the color-fixing agent barrel opening; above the color-fixing agent barrel opening plastic cutting station is... The device includes a cutting blade, a connecting crossbar above the cutting blade, a rotating shaft connected to one end of the connecting crossbar, a bevel gear assembly connected above the rotating shaft, and a reducer motor connected to one end of the bevel gear assembly. The reducer motor is mounted on a lifting plate, and a first lifting cylinder is located in the middle of the lifting plate. A rotary motor is located above the center of the color-fixing agent barrel at the grinding station at the mouth of the color-fixing agent barrel. A connecting plate is fixedly connected to the rotating shaft below the rotary motor, and a first pushing cylinder is located on one side of the connecting plate. A pneumatic rod of the first pushing cylinder contains a... The spring chamber has an opening at the end of the pneumatic rod. A telescopic rod is provided on one side of the opening, extending into the spring chamber and connecting to an internal piston. A spring is provided between the piston and the bottom of one side of the spring chamber. A grinding motor is connected to the end of the telescopic rod. A grinding head is provided on the lower shaft of the grinding motor. A bearing with the same diameter as the grinding head is sleeved on the upper shaft of the grinding head. A second lifting cylinder is vertically arranged above the rotary motor, and the pneumatic rod of the second lifting cylinder is connected to the rotary motor.

[0004] The rotary processing table is driven to rotate by a servo motor.

[0005] The edge array of the rotary processing table has grippers corresponding to the number of workstations.

[0006] The gripper includes a fixed gripper and a movable gripper; a clamping groove with openings facing each other is provided between the fixed gripper and the movable gripper; the fixed gripper is located on the outer ring of the rotary processing table, and the movable gripper is located on the inner ring of the rotary processing table; the movable gripper, the fixed gripper, and the center point of the rotary processing table are on the same straight line, and the movable gripper clamps and releases back and forth along this straight line; the inner ring of the clamping groove is provided with anti-slip rubber.

[0007] A stationary guide block is located in the center of the rotating processing table. The guide block includes an arc-shaped protrusion and a flat portion. The line connecting the fixed grippers at the fixing agent barrel feeding station and the fixing agent barrel feeding station to the center point of the guide block is located on the flat portion. The distance from the flat portion to the fixed gripper is greater than the distance from the protrusion to the fixed gripper. Limit grooves are provided along the arc surface of the four side walls of the guide block. A connecting rod is provided on the side of the movable gripper near the limit groove. The end of the connecting rod extends into the limit groove and is provided with a rolling bearing. There are two rolling bearings, one above the other, which limit the movement of the limit groove on the upper and lower sides respectively. Limit baffles are provided on both sides of the movable gripper. When the rolling bearing on the connecting rod moves to the protrusion, the movable gripper pushes and clamps the fixing agent barrel.

[0008] A positioning plate is installed above the fixing station at the mouth of the fixing agent barrel. The positioning plate is driven to move up and down by a third lifting cylinder. A pressing port is installed on the positioning plate at the position directly corresponding to the fixing agent barrel at the fixing station.

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

[0019] See Figure 1-6 .

[0020] This invention discloses a processing device for a color-fixing agent barrel after blow molding, including a rotary processing table 1. Multiple processing stations are arranged in a circular array around the rotary processing table 1. The rotary processing table 1 rotates the color-fixing agent barrel 2, which passes through each processing station sequentially. The upper edge of the rotary processing table is sequentially provided with a color-fixing agent barrel feeding station 3, a first reserved station 4, a color-fixing agent barrel opening plastic cutting station 5, a color-fixing agent barrel opening grinding station 6, a color-fixing agent barrel opening shaping station 7, a second reserved station 8, and a color-fixing agent barrel delivery station 9. A cutting blade 51 is provided at the color-fixing agent barrel opening plastic cutting station for rotary cutting. A grinding head 61 is provided at the color-fixing agent barrel opening grinding station for grinding the plastic burrs generated when cutting off excess plastic at the color-fixing agent barrel opening plastic cutting station. A shaping barrel cover 21 feeding device is provided at the color-fixing agent barrel opening shaping station 7. A pressing plate 73 is installed above the shaping station 7 to press the shaping bucket lid onto the opening of the color-fixing agent bucket. A cutting blade 51 is installed above the plastic cutting station 5 at the opening of the color-fixing agent bucket. A connecting crossbar 52 is installed above the cutting blade 51. One end of the connecting crossbar is connected to a rotating shaft 53. A bevel gear group 54 is connected above the rotating shaft. One end of the bevel gear group is connected to a reducer motor 55. The reducer motor is installed on a lifting plate 56. A first lifting cylinder 57 is installed in the middle of the lifting plate. In order to prevent the shape of the color-fixing agent bucket opening from changing significantly, such as being squeezed or other factors, if the cutting blade 51 is completely flush with the bucket opening, it is easy for the cutting blade 51 to press against the bucket wall or simply be outside and not be able to cut. Therefore, the cutting blade 51 is positioned about 1 cm away from the edge of the normally shaped color-fixing agent bucket opening. This way, excess plastic can be cut off while ensuring that most buckets are not cut incorrectly.

[0021] Since the previous process left 1 cm of excess plastic, it is preferable to install a rotary motor 62 above the center of the fixing agent barrel at the fixing agent barrel polishing station 6. A connecting plate 63 is fixedly connected to the rotating shaft below the rotary motor 62. A first push cylinder 64 is installed on one side of the connecting plate. A spring cavity 65 is installed inside the pneumatic rod of the first push cylinder 64. An opening of the spring cavity is provided at the end of the pneumatic rod. A telescopic rod 66 is installed on one side of the opening. The telescopic rod 66 extends into the spring cavity 65 and is connected to the piston 67 inside. A spring 68 is installed between the piston and the bottom of one side of the spring cavity. A polishing motor is connected to the end of the telescopic rod. A polishing head is installed on the lower rotating shaft of the polishing motor. A bearing 69 with the same diameter as the polishing head is sleeved on the rotating shaft above the polishing head. A second lifting cylinder 610 is vertically installed above the rotary motor. The pneumatic rod of the second lifting cylinder 610 is connected to the rotary motor 62. The purpose of the spring and telescopic rod 66 is to address the same issue as the previous process: when the barrel wall is not perfectly uniform, it will either not be able to be polished cleanly or the polishing head will be exposed. Therefore, the elastic structure is designed to ensure that the polishing is complete. To prevent the elastic structure from causing excessive polishing, the bearing 69 is provided so that when the bearing 69 is in contact with the barrel opening, the polishing will not be excessive.

[0022] The rotary processing table is driven to rotate by a servo motor.

[0023] The edge array of the rotary processing table has grippers corresponding to the number of workstations.

[0024] The gripper includes a fixed gripper 10 and a movable gripper 11; a clamping groove 12 with openings facing each other is provided between the fixed gripper and the movable gripper; the fixed gripper 10 is located on the outer ring of the rotary processing table 1, and the movable gripper 11 is located on the inner ring of the rotary processing table 1; the center points of the movable gripper 11, the fixed gripper 10 and the rotary processing table 1 are on the same straight line, and the movable gripper 11 clamps and releases back and forth on this straight line; the inner ring of the clamping groove is provided with anti-slip rubber.

[0025] A fixed guide block 13 is provided in the middle of the rotating processing table. The guide block 13 includes an arc-shaped protrusion 131 and a flat part 132. The line connecting the fixed gripper at the fixing agent barrel feeding station 3 and the fixing agent barrel feeding station 9 and the center point of the guide block is located on the flat part 132. The distance from the flat part to the fixed gripper is greater than that of the protrusion. Limiting grooves 133 are provided along the arc surface of the four sides of the guide block. A connecting rod 111 is provided on the side of the movable gripper 11 near the limiting groove 133. The end of the connecting rod extends into the limiting groove and is provided with a rolling bearing 112. There are two bearings, one above the other, which are respectively limited on the upper and lower sides of the limiting groove. Limiting baffles 14 are provided on both sides of the movable gripper. When the bearing on the connecting rod moves to the protrusion, the movable gripper pushes and tightens the fixing agent barrel. The fixed gripper 10 of this device is completely fixed to the rotary processing table 1. The fixed gripper 10 is fixed to the base of the outer ring of the rotary processing table 1 by bolts. The movable gripper has limiters on both sides, so it can only perform two actions: tightening and loosening. The rolling bearing 112 is limited by the limit groove 133 and can only roll along the guide block 13. Therefore, the movable gripper 11 is loosened when it is flat and tightened when it is convex. This design allows the six pairs of grippers to be controlled by different mechanical structures and control programs, which simplifies the structure of the equipment and makes the equipment more reliable when the expected effect is achieved.

[0026] A positioning plate 71 is provided above the fixing station 7 at the mouth of the fixing agent barrel. The positioning plate 71 is driven to move up and down by a third lifting cylinder 72. A pressing port 711 is provided on the positioning plate at the position directly corresponding to the fixing agent barrel at the fixing station. The diameter of the pressing port is larger than the diameter of the fixing barrel cover 21. A pressing plate 73 is provided above the pressing port. The pressing plate is driven to press by a pressing cylinder 74. An arc-shaped stop 712, consistent with the side wall of the pressing port, is provided on the side of the positioning plate 71 away from the arc-shaped stop 712. An arc-shaped pushing block 76 is provided on the side of the pushing plate 75 away from the arc-shaped stop. The arc-shaped pushing block is driven to push by a pushing cylinder 761. An inclined guide plate 77 is provided on the side of the pushing plate adjacent to the arc-shaped pushing block. A conveyor belt 78 is provided on the upper side of the inclined guide plate. When not in use, the positioning plate 71 is raised upwards; otherwise, it would block the rotation when the rotary processing table 1 rotates. When it is necessary to press the solid barrel lid 21, the positioning plate 71 is lowered, and the arc-shaped push block 76 is pushed to the pressing port. Under the action of the arc-shaped stop block 712, it is precisely aligned and pressed. After that, both the pressing plate 73 and the positioning plate 71 are raised upwards.

[0027] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
