Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing cutting technology, specifically to an automatic heat shrink tubing cutting machine. Background Technology

[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material, while the inner layer contains low-melting-point hot melt adhesive. It offers advantages such as insulation, corrosion resistance, wear resistance, waterproofing, sealing, and high adhesion. Heat shrink tubing can be directly applied to cables, shrinking upon heating to tightly adhere to the cable surface, forming an insulating layer that effectively prevents current leakage and short circuits, protecting circuit safety. Furthermore, heat shrink tubing is widely used for waterproofing and leak-proofing wiring in electronic equipment, and for corrosion protection at wire branches.

[0003] Currently, the existing heat shrink tubing cutting process requires the use of a heat shrink tubing cutter. Its working principle is as follows: the long roll of heat shrink tubing is placed on the material tray, the heat shrink tubing is passed through the guide strip, the heat shrink tubing is pressed by rollers, and the heat shrink tubing is driven forward by the rollers to the bottom of the cutter. The cutter cuts the heat shrink tubing into small segments, thereby completing the heat shrink tubing cutting work.

[0004] In the above-mentioned solution, existing heat shrink tubing cutting machines, in order to improve the cutting efficiency, feed multiple heat shrink tubings side by side into the heat shrink tubing cutting machine and set a separating groove at the feed end of the heat shrink tubing cutting machine to separate the multiple heat shrink tubings; however, this method can only cut one specification of heat shrink tubing, resulting in a limited range of applications for the heat shrink tubing cutting machine. When it is necessary to cut heat shrink tubing of different specifications, it is necessary to change to a heat shrink tubing cutting machine of a different specification, thereby increasing production costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic heat shrink tubing cutting machine. By providing a separating component, a cutting component and an intermittent feeding mechanism, it can continuously cut heat shrink tubing of the required specifications, solving the problem that the prior art can only cut heat shrink tubing of one specification, thereby improving practicality and reducing production costs.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] An automatic heat shrink tubing cutting machine includes a worktable, a feeding rack installed on the upper end of the worktable, multiple heat shrink tubing reels arranged on the feeding rack, a body arranged on the upper end of the worktable, two rollers arranged vertically connected to the body, a separating component and a cutting component arranged on the upper end of the body, and an intermittent feeding mechanism arranged in the body, the intermittent feeding mechanism including a linkage component and an intermittent feeding component.

[0008] When multiple heat shrink tubing needs to be cut simultaneously, the separating component is adjusted to change the spacing between them to accommodate heat shrink tubing of different specifications. Heat shrink tubing is then released from multiple tubing reels and placed within the various spacing intervals of the separating component, with the ends of the tubing positioned between two rollers. The intermittent feeding component is activated, causing one roller to rotate intermittently. Simultaneously, the other roller rotates intermittently under the action of the linkage component, thus intermittently feeding the heat shrink tubing. After the two rollers have moved the heat shrink tubing a certain length, the feeding stops, and the cutting component is activated to cut a certain length of heat shrink tubing. The cutting component is then reset, and the above operation is repeated to continuously cut a certain length of heat shrink tubing.

[0009] By incorporating a separating component, a cutting component, and an intermittent feeding mechanism, heat shrink tubing of the required specifications can be continuously cut, solving the problem that existing technologies can only cut one specification of heat shrink tubing, thereby improving practicality and reducing production costs.

[0010] The utility model is further configured such that: the separating component includes multiple separating rods set on the upper end of the machine body, multiple fixing frames are fixed on the upper end of the machine body, the separating rods are located between the fixing frames and the machine body, multiple screws are inserted on the fixing frames, the multiple screws are set one-to-one with the multiple separating rods, and the screws are screwed into the upper end of the separating rods through the protruding end of the fixing frames.

[0011] With the above technical solution, when it is necessary to adjust the separation spacing, loosen several screws to allow the separator rod to move, so that the separation spacing between the separator rods can be adjusted according to the required specifications of heat shrink tubing. After adjusting the separation spacing, tighten several screws to fix the separator rod in the required position.

[0012] The utility model is further configured such that: the linkage component includes gears fixed to the ends of the two rollers respectively, the two gears meshing with each other, and the intermittent feeding component is disposed on the side wall of one of the gears.

[0013] With the above technical solution, when it is necessary to drive two rollers to rotate intermittently at the same time, the intermittent feeding component is activated, which drives one of the gears to rotate intermittently. The intermittent rotation of one gear drives one of the rollers to rotate intermittently, and at the same time drives the other gear to rotate intermittently, so that both rollers can be driven to rotate intermittently at the same time.

[0014] The utility model is further configured such that: the intermittent feeding assembly includes a motor fixed in the machine body, an intermittent drive block fixed on the output end of the motor, an intermittent actuating rod fixed on the side wall of the intermittent drive block, an intermittent rotating block fixed on the side wall of one of the gears, and a plurality of intermittent rotating grooves that cooperate with the intermittent actuating rod are formed on the side wall of the intermittent rotating block.

[0015] With the above technical solution, when it is necessary to drive one of the rollers to rotate intermittently, the motor is started, which drives the intermittent drive block to rotate. The rotation of the intermittent drive block drives the intermittent actuating rod to rotate. When the intermittent actuating rod rotates into the intermittent rotation groove, the rotation of the intermittent actuating rod will drive the intermittent rotation block to rotate. The rotation of the intermittent rotation block will simultaneously drive one of the gears to rotate, thereby driving one of the rollers to rotate. When the intermittent actuating rod disengages from the intermittent rotation groove, the rotation of the intermittent actuating rod will not drive the intermittent rotation block to rotate, so that one of the rollers will not rotate, thus driving one of the rollers to rotate intermittently.

[0016] The utility model is further configured such that: the cutting component includes a cylinder fixed to the upper end of the machine body, two blade holders are symmetrically fixed to the upper end of the machine body, a cutting blade is inserted into each of the two blade holders at the same time, a cutting block is fixed to the upper end of the machine body that is offset from the cutting blade, and the protruding end of the cutting blade through the blade holder is fixed to the output end of the cylinder.

[0017] With the above technical solution, when heat shrink tubing needs to be cut, the cylinder is activated, which drives the cutter downward, and the heat shrink tubing can be cut under the action of the cutting block.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, by incorporating a separating component, a cutting component, and an intermittent feeding mechanism, heat shrink tubing of the required specifications can be continuously cut, solving the problem that existing technologies can only cut one specification of heat shrink tubing, thereby improving practicality and reducing production costs.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] The following is for reference Figures 1 to 3 This utility model will now be described.

[0026] An automatic heat shrink tubing cutting machine includes a worktable 1, a feeding rack 2 installed on the upper end of the worktable 1, multiple heat shrink tubing reels 3 arranged on the feeding rack 2, a body 4 arranged on the upper end of the worktable 1, two rollers 5 arranged vertically connected inside the body 4, a separating component and a cutting component arranged on the upper end of the body 4, and an intermittent feeding mechanism inside the body 4, the intermittent feeding mechanism including a linkage component and an intermittent feeding component.

[0027] When multiple heat shrink tubing 6 needs to be cut simultaneously, the separating component is adjusted to adjust the spacing of the separating component to accommodate heat shrink tubing 6 of different specifications. Then, the heat shrink tubing 6 on multiple heat shrink tubing reels 3 is released and placed in the multiple spacings of the separating component, with the ends of the heat shrink tubing 6 positioned between two rollers 5. The intermittent feeding component is activated, causing one roller 5 to rotate intermittently. Under the action of the linkage component, the other roller 5 is also driven to rotate intermittently, thus intermittently feeding the heat shrink tubing 6. After the two rollers 5 have moved the heat shrink tubing 6 a certain length, the feeding of the heat shrink tubing 6 can be stopped. Then, the cutting component is activated to cut a certain length of heat shrink tubing 6. The cutting component is then reset, and the above operation is repeated to continuously cut a certain length of heat shrink tubing 6.

[0028] By incorporating a separating component, a cutting component, and an intermittent feeding mechanism, the required specifications of heat shrink tubing 6 can be continuously cut, solving the problem that existing technologies can only cut one specification of heat shrink tubing 6, thereby improving practicality and reducing production costs.

[0029] The separation assembly includes multiple separation rods 7 set on the upper end of the body 4. Multiple fixing frames 8 are fixed on the upper end of the body 4. The separation rods 7 are located between the fixing frames 8 and the body 4. Multiple screws 9 are inserted on the fixing frames 8. The multiple screws 9 are set one-to-one with the multiple separation rods 7. The screws 9 pass through the protruding end of the fixing frame 8 and are screwed to the upper end of the separation rods 7.

[0030] When the separation spacing needs to be adjusted, loosen multiple screws 9 to allow the separator rod 7 to move, so that the separation spacing between the separator rods 7 can be adjusted according to the required specifications of the heat shrink tubing 6. After adjusting the separation spacing, tighten multiple screws 9 to fix the separator rod 7 in the required position.

[0031] The linkage assembly includes gears 10 fixed to the ends of the two rollers 5 respectively, the two gears 10 meshing with each other, and the intermittent feeding assembly is disposed on the side wall of one of the gears 10.

[0032] When it is necessary to drive two rollers 5 to rotate intermittently at the same time, the intermittent feeding component is activated, which drives one of the gears 10 to rotate intermittently. The intermittent rotation of one gear 10 drives one of the rollers 5 to rotate intermittently, and at the same time drives the other gear 10 to rotate intermittently, so that both rollers 5 can be driven to rotate intermittently at the same time.

[0033] The intermittent feeding assembly includes a motor 11 fixed inside the machine body 4, an intermittent drive block 12 fixed on the output end of the motor 11, an intermittent actuating rod 13 fixed on the side wall of the intermittent drive block 12, an intermittent rotating block 14 fixed on the side wall of one of the gears 10, and a plurality of intermittent rotating grooves 1401 formed on the side wall of the intermittent rotating block 14 that cooperate with the intermittent actuating rod 13.

[0034] When it is necessary to drive one of the rollers 5 to rotate intermittently, the motor 11 is started, which drives the intermittent drive block 12 to rotate. The rotation of the intermittent drive block 12 drives the intermittent actuating rod 13 to rotate. When the intermittent actuating rod 13 rotates into the intermittent rotation groove 1401, the rotation of the intermittent actuating rod 13 will drive the intermittent rotation block 14 to rotate. The rotation of the intermittent rotation block 14 will simultaneously drive one of the gears 10 to rotate, thereby driving one of the rollers 5 to rotate. When the intermittent actuating rod 13 disengages from the intermittent rotation groove 1401, the rotation of the intermittent actuating rod 13 will not drive the intermittent rotation block 14 to rotate, so that one of the rollers 5 will not rotate, thus driving one of the rollers 5 to rotate intermittently.

[0035] The cutting assembly includes a cylinder 15 fixed to the upper end of the machine body 4. Two blade holders 16 are symmetrically fixed to the upper end of the machine body 4. A cutting blade 17 is inserted into each of the two blade holders 16. A cutting block 18 is fixed to the upper end of the machine body 4, which is offset from the cutting blade 17. The protruding end of the cutting blade 17 passes through the blade holder 16 and is fixed to the output end of the cylinder 15.

[0036] When the heat shrink tubing 6 needs to be cut, the cylinder 15 is activated, which drives the cutter 17 to move downwards, and under the action of the cutting block 18, the heat shrink tubing 6 can be cut.

[0037] Working principle:

[0038] When multiple heat shrink tubing 6 needs to be cut simultaneously, loosen multiple screws 9 to allow the separator rods 7 to move. This allows adjustment of the spacing between the separator rods 7 according to the required specifications of the heat shrink tubing 6. After adjusting the spacing, tighten the multiple screws 9 to fix the separator rods 7 in the required position. Then, release the heat shrink tubing 6 from the multiple heat shrink tubing reels 3 and place the multiple heat shrink tubing 6 into the multiple spacing intervals, ensuring that the ends of the heat shrink tubing 6 are between the two rollers 5. Start the motor 11 to drive the intermittent drive block 12 to rotate. The rotation of the intermittent drive block 12 drives the intermittent actuating rod 13 to rotate. When the intermittent actuating rod 13 rotates into the intermittent rotation groove 1401... When the intermittent actuating lever 13 rotates, it actuates the intermittent rotating block 14. The rotation of the intermittent rotating block 14 simultaneously drives one of the gears 10 to rotate, which in turn drives one of the rollers 5 to rotate. Simultaneously, it drives the other gear 10 to rotate, thus simultaneously driving both rollers 5 to rotate. When the intermittent actuating lever 13 disengages from the intermittent rotating groove 1401, the rotation of the intermittent actuating lever 13 will not actuate the intermittent rotating block 14, preventing one of the rollers 5 from rotating. This allows both rollers 5 to rotate intermittently, thus intermittently conveying the heat shrink tubing 6. After the two rollers 5 have moved the heat shrink tubing 6 a certain distance, the conveying of the heat shrink tubing 6 can be stopped.

[0039] Then, start cylinder 15 to drive cutter 17 to move downwards, and under the action of cutting block 18, a certain length of heat shrink tubing 6 can be cut. Then control cutter 17 to reset and repeat the above operation to continuously cut a certain length of heat shrink tubing 6.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
