Description

Technical Field

[0001] This utility model relates to the field of non-standard automation technology, specifically to a buffer mechanism for an alloy resistance tape packaging machine. Background Technology

[0002] In the production process of alloy resistors, tape and reel packaging is a crucial step. Tape and reel packaging machines use carrier tape to collect and protect the alloy resistors, facilitating subsequent storage, transportation, and use. During the tape and reel packaging process, the carrier tape needs to be continuously fed; when the tape material on the take-up reel is used up, a reel replacement operation is required.

[0003] However, if the carrier tape is not effectively buffered during the reel change process, it will cause interruption of the carrier tape transport, affecting the continuous operation of the packaging machine and reducing production efficiency. At the same time, if the carrier tape has excessive friction with related components during transport and buffering, it is easy to damage the carrier tape, affecting the packaging quality of the alloy resistors.

[0004] Therefore, it is of great significance to provide a buffer mechanism for alloy resistance tape packaging machines to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a buffer mechanism for an alloy resistor tape and reel packaging machine to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A buffer mechanism for an alloy resistance tape packaging machine includes a housing. An upper bracket is fixedly mounted on the top front of the housing, and an upper pulley is rotatably mounted within the upper bracket. A vertical groove is formed on the front of the housing, and a sliding block is slidably fitted within the groove. One end of the sliding block is fixedly connected to a lower bracket, and a lower pulley is rotatably mounted within the lower bracket. A support plate is fixedly mounted inside the housing, and a guide rod is fixedly connected between the support plate and the bottom of the housing. The sliding block slidably engages with the guide rod. A third motor is mounted on the top of the support plate, and the output shaft of the third motor is connected to a lead screw via a coupling. The lead screw and the sliding block form a threaded transmission engagement.

[0008] A second motor for driving the upper pulley is installed on one side of the upper bracket, and a first motor for driving the lower pulley is installed on one side of the lower bracket.

[0009] The lower pulley and the upper pulley are arranged vertically to each other, and the circumferential surfaces of the lower pulley and the upper pulley are each provided with a plurality of spacer rings for positioning.

[0010] The front of the equipment housing is also provided with a rotatable take-up reel for taking up the braided material; a swing arm, one end of which is hinged to the equipment housing; and a pressure roller, which is fixedly installed on the free end of the swing arm for applying pressure to the braided material.

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

[0012] 1. This invention enables effective buffering of the carrier belt: During reel changing, the lower pulley descends to buffer a certain length of carrier belt, ensuring uninterrupted carrier belt transport during the reel changing process; after reel changing, the lower pulley rises to release the buffered carrier belt, ensuring the packaging machine can continue to operate normally, improving production continuity and efficiency. It also reduces friction on the carrier belt: Both the upper and lower pulleys rotate automatically under the drive of the motor. When the carrier belt passes over the two sets of pulleys, the rotation of the pulleys is synchronized with the transport of the carrier belt, greatly reducing friction between the carrier belt and the pulleys, preventing damage to the carrier belt due to friction, and ensuring the packaging quality of the alloy resistors.

[0013] 2. Accurate positioning: The circumferential surfaces of both the lower and upper pulleys are equipped with multiple positioning rings at intervals, which can accurately position the carrier belt and prevent the carrier belt from shifting during conveying and buffering, thus further ensuring the accuracy of packaging.

[0014] 3. Stable and reliable structure: The guide rod guides the sliding block, ensuring the stability of the lower roller during the lifting process; the threaded transmission between the screw and the sliding block makes the lifting control of the lower roller precise and reliable.

[0025] Please see Figure 1-2 This utility model provides a technical solution for a buffer mechanism in an alloy resistance tape packaging machine:

[0026] A buffer mechanism for an alloy resistance tape packaging machine includes a housing 1. An upper bracket 8 is fixedly installed on the top front of the housing 1. An upper pulley 9 is rotatably disposed inside the upper bracket 8. A second motor 10 for driving the upper pulley 9 is installed on one side of the upper bracket 8. When the second motor 10 is working, it can drive the upper pulley 9 to rotate.

[0027] The front of the device housing 1 has a vertical groove 11 along the vertical direction. A sliding block 13 is slidably fitted in the vertical groove 11. One end of the sliding block 13 is fixedly connected to a lower bracket 4. A lower pulley 2 is rotatably installed in the lower bracket 4. A first motor 3 for driving the lower pulley 2 is installed on one side of the lower bracket 4. When the first motor 3 is working, it can drive the lower pulley 2 to rotate. The lower pulley 2 and the upper pulley 9 are arranged vertically correspondingly, and multiple positioning rings are spaced apart on the circumferential surfaces of the lower pulley 2 and the upper pulley 9. The positioning rings can play a good positioning role for the carrier belt and prevent the carrier belt from deviating.

[0028] A support plate 15 is fixedly installed inside the equipment housing 1. A guide slide rod 12 is fixedly connected between the support plate 15 and the bottom of the equipment housing 1. The sliding block 13 is slidably engaged with the guide slide rod 12. The guide slide rod 12 provides guidance for the sliding of the sliding block 13, ensuring the stability of the sliding block 13's movement. A third motor 16 is installed at the top of the support plate 15. The output shaft of the third motor 16 is connected to a lead screw 14 via a coupling. The lead screw 14 and the sliding block 13 form a threaded transmission engagement. When the third motor 16 is working, it drives the lead screw 14 to rotate, thereby driving the sliding block 13 to slide up and down along the guide slide rod 12, thus realizing the lifting and lowering of the lower roller 2.

[0029] The front of the equipment housing 1 is also provided with a rotatable take-up reel 6 for taking up the braided material; a swing arm 5, one end of which is hinged to the equipment housing 1; and a pressure roller 7, which is fixedly installed on the free end of the swing arm 5, for applying pressure to the braided material to ensure the tension of the braided material during the winding process.

[0030] Working principle

[0031] Under normal operating conditions, the carrier belt passes over the lower pulley 2 and the upper pulley 9 in sequence. The upper pulley 9 rotates under the drive of the second motor 10, and the lower pulley 2 rotates under the drive of the first motor 3. The rotation directions of the upper pulley 9 and the lower pulley 2 are matched with the conveying direction of the carrier belt, thereby reducing the friction between the carrier belt and the pulleys.

[0032] When a disc needs to be changed, the third motor 16 operates, driving the lead screw 14 to rotate, causing the sliding block 13 to slide downward along the guide slide rod 12, which in turn drives the lower support 4 and the lower pulley 2 to descend. At this time, the carrier belt is gradually buffered during the descent of the lower pulley 2.

[0033] After the reel is changed, the third motor 16 reverses its operation, causing the lead screw 14 to rotate in the opposite direction. This causes the sliding block 13 to slide upward along the guide slide rod 12, which in turn causes the lower support 4 and the lower pulley 2 to rise, releasing the buffered carrier belt and ensuring continuous transport of the carrier belt.

[0034] Throughout the process, the take-up reel 6 winds up the braided material, and the pressure roller 7 at the free end of the swing arm 5 applies pressure to the braided material to ensure its tension and the smooth progress of the packaging work.

[0035] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
