Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat shrink sleeve processing technology, specifically a cutting device for PVC heat shrink sleeves. Background Technology
[0002] PVC heat shrink tubing is a type of heat shrink tubing made of polyvinyl chloride (PVC). It is flexible and elastic, and shrinks when heated to 70-90℃ (standard type) or above 98℃ (transparent type).1 PVC heat shrink tubing is widely used for insulation protection of various wire harnesses, solder joints, and inductors, as well as for rust and corrosion prevention of metal pipes and rods.
[0003] Existing heat shrink sleeves require pre-cutting before use. Workers cannot accurately cut the required length and the cut edges cannot be kept neat. Alternatively, they can flatten the sleeve and cut it with tools such as utility knives, but this will cause indentations on the heat shrink sleeve and affect its appearance after use. Therefore, a cutting device that can automatically cut the sleeve without damaging its overall appearance is needed to assist workers.
[0004] Therefore, it is necessary to design a cutting device for PVC heat shrink sleeves that is practical and easy to cut. Utility Model Content
[0005] The purpose of this invention is to provide a cutting device for PVC heat shrink sleeves to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for PVC heat shrink sleeves, comprising a base, a first slider slidably connected above the base, a controller disposed above the first slider, a first connecting plate rotatably connected above the controller, a second connecting plate disposed above the controller, a connecting block rotatably connected above the first connecting plate, the connecting block and the second connecting plate being rotatably connected to each other, a telescopic device disposed above the controller, a third connecting plate disposed at the telescopic end of the telescopic device, the third connecting plate being rotatably connected to the first connecting plate, a first buffer disposed on the inner side of the connecting block, and a first clamping plate disposed on the inner side of the first buffer.
[0007] According to the above technical solution, a support column is provided above the base, a sleeve is provided on the rear side of the support column, a support plate is slidably connected to the front side of the support column, a limit plate is provided on the front side of the support plate, and a second buffer is provided on the front side of the support plate.
[0008] According to the above technical solution, an adapter frame is slidably connected to the top of the base, a slider is provided on the rear side of the adapter frame, and a positioner is slidably connected to the inner side of the slider.
[0009] According to the above technical solution, the bottom of the transducer is provided with a clamping assembly, the clamping end of the clamping assembly is provided with a third buffer, and the top of the third buffer is provided with a second clamping plate.
[0010] According to the above technical solution, a slide is provided on the rear side of the second clamping plate, and a control compartment is slidably connected to the inner side of the slide.
[0011] According to the above technical solution, a fourth buffer is provided on the inner side of the control compartment, and a cutting blade is provided on the top of the fourth buffer.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0013] (1) By setting a cutting blade, the control chamber slides from top to bottom in the slide, thereby driving the cutting component to perform fast and accurate cutting. The fourth buffer can buffer the pressure of the cutting blade on the heat shrink sleeve, preventing excessive pressure from damaging the cutting blade or sleeve. After the cutting is completed, the worker first removes the excess heat shrink sleeve, takes out the cut heat shrink sleeve and the waste material held by the first clamping plate, and completes the cutting.
[0014] (2) With the positioner set, the adapter descends to the specified height after the heat shrink sleeve reaches the specified area. Then, the sliding device drives the cutting component to move. The worker sets the length to be cut in advance. Then the sliding device is adjusted. The positioner will cut at the end first and then go to the first clamping plate to cut at the top.
[0015] (3) With the sleeve provided, the worker puts the heat shrink sleeve on the sleeve, and then the first clamping plate gathers together and clamps the heat shrink sleeve with appropriate clamping force. The first slider moves backward on the base. The inner side of the first clamping plate is made of high-friction rubber material, and the surface of the sleeve is made of smooth material. At this time, the first clamping plate can drive the heat shrink sleeve to move backward together. When the first clamping plate touches the limit plate, it means that the designated area has been reached. Then the first slider stops moving. The second buffer buffers the thrust during the displacement and then slowly recovers by using the rebound force to ensure that the first clamping plate is in the designated position, thereby assisting the worker to put the heat shrink sleeve on the sleeve and then prepare for cutting.
