Description

[0001] This invention is a divisional application of "Heat shrink tubing shearing device for processing power supply system busbars and its usage method" (application number: 2022105761624; application date: 2022-05-25). Technical Field

[0002] This invention belongs to the field of power distribution technology, and specifically relates to a method for cutting heat shrink tubing used in the processing of power supply system busbars. Background Technology

[0003] During the processing of some busbars, heat shrink tubing (insulating sleeves) needs to be fitted onto the outside of the busbars. Currently, the heat shrink tubing purchased to the factory does not have a dedicated receiving device with a cutting function. Each time a section of heat shrink tubing needs to be cut, the corresponding model must be found and cut with scissors. Generally, companies have a wide variety of heat shrink tubing models, making the search for the correct specification time-consuming. Therefore, there is an urgent need for a device that can centrally organize different specifications and models of heat shrink tubing, while simultaneously solving the problems of rapid cutting and easy replacement. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the present invention provides a heat shrink tubing cutting method for processing power supply system busbars. The present invention can install heat shrink tubing of different specifications in a heat shrink tubing reel storage box, which is convenient for classification and storage, and achieves the purpose of taking it out as needed. Within the limited space of the heat shrink tubing reel storage box, it maximizes the capacity of more heat shrink tubing reels, while also taking into account the problem of convenient retrieval and placement.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A method for cutting heat shrink tubing for processing power supply system busbars includes a heat shrink tubing cutting device, which includes a heat shrink tubing reel receiving box, a telescopic cutting mechanism, a telescopic pressure roller, and a machine housing; the heat shrink tubing reel receiving box is provided with a row of heat shrink tubing reel receiving slots. S1: Adjust the orientation of the heat shrink tubing reel to ensure that the heat shrink tubing can be pulled out from the bottom of the entire heat shrink tubing reel; S2: Insert the heat shrink tubing reel from the top of the heat shrink tubing reel receiving groove into the heat shrink tubing reel receiving groove, and ensure that the positioning pin is located in the feed positioning guide groove during the insertion process; At this time, the telescopic cutting mechanism and the telescopic pressure roller are in their initial positions, that is, the pressure roller is in its lowest position, and the cutting blades are retracted into the machine box. S3: Lift the handle upwards while rotating the heat shrink tubing reel, causing the starting end of the heat shrink tubing to fall towards the heat shrink tubing outlet. Because the heat shrink tubing outlet is high, the starting end of the heat shrink tubing will extend out of the heat shrink tubing outlet while rotating the heat shrink tubing reel. S4: Release the handle to allow the pressure roller to press down on the heat shrink tubing; S5: When a section of heat shrink tubing needs to be cut, pull the heat shrink tubing outward. Since the positioning pin is located in the feed positioning guide groove at this time, the heat shrink tubing reel rotates around the positioning pin. As the heat shrink tubing reel rotates, the diameter of the entire heat shrink tubing reel gradually decreases, and the entire heat shrink tubing reel moves downward. S6: After the heat shrink tubing is pulled out to the required length, press down the operating lever to cut the heat shrink tubing with the cutting blades; release the operating lever, and the cutting blades will be reset by the spring and retract into the machine housing. Because the pressure roller is always pressing on the heat shrink tubing, the movement of the heat shrink tubing is relatively smooth; because the cutting blade is located on the outside of the pressure roller, the heat shrink tubing always leaves a certain distance outside the heat shrink tubing outlet for easy retrieval next time. S7: As the amount of heat shrink tubing decreases, the entire heat shrink tubing reel gradually moves downwards. When the heat shrink tubing on the reel is used up, the positioning pin is just located at the turning point of the folded guide groove. S8: After completely removing the remaining heat shrink tubing, open the core tray discharge gate. The core tray rolls out from the core tray discharge gate along the wedge-shaped bottom plate. S9: Replace the heat shrink tubing reel with a new one following steps S1-S2.

[0006] Preferably, each heat shrink tubing reel receiving groove has a wedge-shaped bottom plate at the bottom, a core disc discharge gate on one side wall of the heat shrink tubing reel receiving groove, and a heat shrink tubing discharge port on the other side wall; both inner walls of the heat shrink tubing reel receiving groove are provided with folded guide grooves, which include infeed positioning guide grooves and discharge guide grooves, and the inclination angle of the discharge guide grooves is adapted to the slope of the wedge-shaped bottom plate; a discharge support plate is provided at the heat shrink tubing discharge port, and a telescopic cutting mechanism and a telescopic pressure roller are provided above the support plate; the heat shrink tubing reel receiving groove is used to place the heat shrink tubing reel, a core disc is provided in the middle of the heat shrink tubing reel, and positioning pins are provided at the center of both sides of the core disc, with the positioning pins slidingly engaged with the folded guide grooves.

[0007] Preferably, each heat shrink tubing reel receiving slot corresponds to a heat shrink tubing reel of a certain specification; the feed positioning guide groove is vertically arranged, and the discharge guide groove is parallel to the slope of the wedge-shaped bottom plate; the heat shrink tubing reel is used to be placed from the top of the heat shrink tubing reel receiving slot, and the positioning pin is located in the folded guide groove. The discharge guide chute extends to the core disk discharge gate, and the vertical distance between the turning point of the folded guide chute and the slope of the wedge-shaped bottom plate is equal to the radius of the core disk.

[0008] Preferably, both the telescopic cutting mechanism and the telescopic pressure roller are mounted on the machine housing, which is mounted on the outer wall of the heat shrink tubing reel receiving box; The telescopic pressure roller includes a pressure roller, which is connected to a lifting rod. The lifting rod is connected to the machine housing via a spring. The top of the lifting rod passes through the machine housing, and a carrying plate is connected to the top of the lifting rod. The telescopic cutting mechanism includes a cutting blade, which is driven to move up and down by an operating lever. The operating lever is connected to the machine housing via a spring.

[0009] This patent can achieve the following beneficial effects: 1. This invention can install heat shrink tubing of different specifications in a heat shrink tubing reel container, which is convenient for classification and storage, and can be used and retrieved at any time. Within the limited space of the heat shrink tubing reel container, it can accommodate a larger number of heat shrink tubing reels, while also taking into account the problem of convenient access.

[0010] 2. After the heat shrink tubing reel is placed into the heat shrink tubing reel receiving slot, as the amount of heat shrink tubing on the reel decreases, the entire heat shrink tubing reel will move downwards. When the heat shrink tubing on the reel is used up, the positioning pin is exactly at the turning point of the folded guide groove. Open the core tray discharge door. Because the wedge-shaped bottom plate has an inclined slope, the core tray will automatically roll to the side of the core tray discharge door, making it easy to remove the core tray.

[0011] 3. The cutting blade is located outside the pressure roller. This ensures that after each cut, a section of the heat shrink tubing remains outside the outlet for easy retrieval. The height of the heat shrink tubing outlet is significantly greater than its thickness, allowing the initial end to extend beyond the outlet. To compensate for the excessive outlet height and resulting large range of motion, a telescopic pressure roller is added to prevent the heat shrink tubing from loosening.

Detailed Implementation Preferred solutions include Figures 1 to 8 As shown, a method for cutting heat shrink tubing for processing power supply system busbars employs a heat shrink tubing cutting device. The device includes a heat shrink tubing reel receiving box 1, which has a row of heat shrink tubing reel receiving slots 2. Each slot 2 has a wedge-shaped bottom plate 3 at its bottom. One side wall of each slot 2 has a core plate discharge gate 4, and the other side wall has a heat shrink tubing discharge port 5. Both inner walls of the heat shrink tubing reel receiving slots 2 are provided with folded guide grooves. The guide channel includes an infeed positioning guide channel 6.1 and an outfeed guide channel 6.2. The inclination angle of the outfeed guide channel 6.2 is adapted to the slope of the wedge-shaped base plate 3. An outfeed support plate 7 is provided at the heat shrink tubing outlet 5. A telescopic cutting mechanism 8 and a telescopic pressure roller 9 are provided above the support plate 7. The heat shrink tubing reel receiving groove 2 is used to place the heat shrink tubing reel 10. A core plate 10.1 is provided in the middle of the heat shrink tubing reel 10. Positioning pins 10.2 are provided at the center of both sides of the core plate 10.2 and the positioning pins 10.2 slide with the folded guide channel.

[0013] Each heat shrink tubing reel receiving slot 2 corresponds to a heat shrink tubing reel 10 of a certain size; each size of heat shrink tubing reel receiving slot 2 has a corresponding model mark on its top. The width of the heat shrink tubing reel 10 is adapted to the width of the heat shrink tubing reel receiving slot 2 to maximize the space utilization of the heat shrink tubing reel receiving box 1.

[0014] Furthermore, because the width of the heat shrink tubing reel receiving groove 2 is relatively narrow, generally between 5-10 cm, and the depth of the heat shrink tubing reel receiving groove 2 is relatively deep, generally between 40-60 cm, it is difficult for operators to reach into the heat shrink tubing reel receiving groove 2 after the heat shrink tubing reel 10 is placed inside. It is also inconvenient to adjust the heat shrink tubing reel 10, especially after the heat shrink tubing reel 10 is completely used up, making it difficult to remove the used core reel 10.1. Therefore, to address the above problems, the present invention has made the following improvements: The feeding positioning guide 6.1 is vertically set, and the discharging guide 6.2 is parallel to the slope of the wedge-shaped base plate 3; the heat shrink tubing reel 10 is placed from the top of the heat shrink tubing reel receiving groove 2, and the positioning pin 10.2 is located in the folded guide trough. The discharging guide 6.2 extends to the core plate discharging gate 4, and the vertical distance between the turning point of the folded guide trough and the slope of the wedge-shaped base plate 3 is equal to the radius of the core plate 10.1. The purpose of the above design is as follows: After the heat shrink tubing reel 10 is placed into the heat shrink tubing reel receiving groove 2, as the amount of heat shrink tubing in the reel 10 decreases, the heat shrink tubing reel 10 will move downward as a whole. When the heat shrink tubing 10.3 on the heat shrink tubing reel 10 is used up, the positioning pin 10.2 is just located at the turning point of the folded guide groove. When the core plate discharge door 4 is opened, the core plate 10.1 will automatically roll to the side of the core plate discharge door 4 due to the inclined slope of the wedge-shaped bottom plate 3, thus making it easy to take out the core plate 10.1.

[0015] Furthermore, to facilitate the cutting of heat shrink tubing to a certain length at any time, the present invention has made the following improvements: Both the telescopic cutting mechanism 8 and the telescopic pressure roller 9 are mounted on the housing 11, which is installed on the outer wall of the heat shrink tubing reel housing 1. The telescopic pressure roller 9 includes a pressure roller 9.1, which is connected to a lifting rod 9.2. The lifting rod 9.2 is connected to the housing 11 via a spring, and its top extends through the housing 11, with a handle 9.3 connected to the top. The telescopic cutting mechanism 8 includes a cutting blade 8.1, which is driven up and down by an operating lever 8.2, which is connected to the housing 11 via a spring. Under the action of the spring, the pressure roller 9.1 is initially in a low position and in contact with the discharge tray 7. Under the action of the spring, the operating lever 8.2 is initially positioned with the cutting blade 8.1 inside the housing 11, preventing it from being exposed outside the housing 11 and cutting the operator's hands.

[0016] The cutting blade 8.1 is located outside the pressure roller 9.1. This ensures that after each cut, a section of heat shrink tubing remains outside the heat shrink tubing outlet 5 for easy retrieval. The height of the heat shrink tubing outlet 5 is approximately 10cm, while the thickness of the heat shrink tubing is generally no more than 1cm. The outlet 5 needs a relatively high design to allow the initial end of the heat shrink tubing to extend beyond the outlet 5. For detailed instructions, please refer to the device's operating procedure.

[0017] Furthermore, the tray 7 is provided with a slot 12, which is located directly below the cutting blade 8.1. The cutting blade 8.1 is pressed down and passes through the slot 12 to cut the heat shrink tubing.

[0018] Preferably, such as Figure 9-14 As shown, the heat shrink tubing cutting method for processing power supply system busbars includes the following steps: S1: Adjust the orientation of the heat shrink tubing reel 10 to ensure that the heat shrink tubing 10.3 can be pulled out from the bottom of the entire heat shrink tubing reel 10; S2: Insert the heat shrink tubing reel 10 from the top of the heat shrink tubing reel receiving groove 2 into the heat shrink tubing reel receiving groove 2, and ensure that the positioning pin 10.2 is located in the feeding positioning guide groove 6.1 during the insertion process; At this time, the telescopic cutting mechanism 8 and the telescopic pressure roller 9 are in their initial positions, that is, the pressure roller 9.1 is in its lowest position, and the cutting blade 8.1 is retracted into the machine housing 11. S3: Lift the handle 9.3 upwards and rotate the heat shrink tubing reel 10 at the same time so that the starting end of the heat shrink tubing 10.3 falls toward the heat shrink tubing outlet 5. Because the heat shrink tubing outlet 5 is high, the starting end of the heat shrink tubing 10.3 will extend out from the heat shrink tubing outlet 5 while the heat shrink tubing reel 10 is rotated. S4: Release the handle 9.3 to allow the pressure roller 9.1 to press down on the heat shrink tubing 10.3; S5: When it is necessary to cut a section of heat shrink tubing 10.3, pull the heat shrink tubing 10.3 outward. Since the positioning pin 10.2 is located in the feed positioning guide groove 6.1 at this time, the heat shrink tubing reel 10 rotates around the positioning pin 10.2. While the heat shrink tubing reel 10 rotates, the diameter of the entire heat shrink tubing reel 10 gradually decreases, and the heat shrink tubing reel 10 moves downward as a whole. S6: After the heat shrink tubing 10.3 is pulled out to the required length, press down the operating lever 8.2 and use the cutting blade 8.1 to cut the heat shrink tubing 10.3; release the operating lever 8.2, and the cutting blade 8.1 will be reset by the spring and retract into the housing 11. Because the pressure roller 9.1 always presses on the heat shrink tube 10.3, the movement of the heat shrink tube 10.3 is relatively smooth; because the cutting blade 8.1 is located outside the pressure roller 9.1, the heat shrink tube 10.3 always leaves a distance outside the heat shrink tube outlet 5 for easy removal next time. S7: As the amount of heat shrink tubing 10.3 decreases, the entire heat shrink tubing reel 10 gradually moves downward. When the heat shrink tubing 10.3 on the heat shrink tubing reel 10 is used up, the positioning pin 10.2 is just located at the turning point of the folded guide groove. S8: After completely pulling out the remaining heat shrink tubing 10.3, open the core tray discharge gate 4, and the core tray 10.1 rolls out from the core tray discharge gate 4 along the wedge-shaped bottom plate 3; S9: Replace the heat shrink tubing reel 10 following steps S1-S2.

[0019] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
