Description

Technical Field

[0001] This utility model relates to the field of ceramic flat film manufacturing technology, and in particular to a ceramic flat film cutting device. Background Technology

[0002] Currently, ceramic flat sheet films are mainly cut manually or using roller cutters after extrusion molding. These methods have the following technical drawbacks:

[0003] Manual cutting: The cutting efficiency is low, the cutting size is not easy to control, and the straightness of the clay blank and the flatness of the cut are poor after cutting. This results in the ceramic flat film being curved after sintering and the cut surface being uneven. It is necessary to cut it a second time to make the cut surface flat in order to facilitate subsequent encapsulation. If the cut surface is uneven, it is easy to cause glue leakage during encapsulation.

[0004] Roller cutting: The cutting size can be precisely controlled, but the roller cutting requires applying external force to the clay blank on one side, which leads to a decrease in the straightness of the clay blank. After cutting, it is easy to produce a "large blade" shape, which causes the shape to bend after sintering and makes it impossible to filter and assemble. Summary of the Invention

[0005] The present invention aims to address the shortcomings of the prior art by providing a ceramic flat film cutting device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a ceramic flat film cutting device, comprising:

[0007] The feeding unit includes two belt conveyors spaced apart, with continuous baffles on the front and rear sides of the two belt conveyors. The baffles are equipped with limiting mechanisms to prevent the mud blanks from deviating. The center of the drive roller of the belt conveyor located at the input end is equipped with a rotary encoder for speed measurement via a coupling.

[0008] The follow-up cutting unit includes a support plate set at the bottom of the outer side of the baffle, a horizontal linear slide on the top of the support plate, a vertical linear slide on the top of the slider of the horizontal linear slide, a cutting beam between the opposing surfaces of the sliders of the two vertical linear slides, a blade mounting seat at the bottom of the cutting beam, a cutting blade detachably mounted on the bottom of the blade mounting seat, a cutting block between the opposing surfaces of the two baffles, and the cutting block is located in the gap between the two belt conveyors. A force sensor is embedded in the bottom of the cutting block to prevent the cutting blade from overcutting.

[0009] The control unit is connected to two belt conveyors, a rotary encoder, and a follow-up cutting unit. It is used to start the follow-up cutting unit when the clay blank reaches 70-100mm before the set cutting length, so that the cutting blade moves at the same speed and in the same direction as the clay blank and completes the cutting.

[0010] Specifically, the limiting mechanism includes several threaded sleeves that are fixed to the baffle. The threaded sleeves are internally threaded with screws. The screws are provided with a handwheel at the outer end of the baffle and a limiting plate at the inner end of the baffle.

[0012] Specifically, the blade mounting base has a blade groove at the bottom, and the top of the cutting blade is inserted into the blade groove and fixed by bolts.

[0013] The beneficial effects of this utility model are: by setting up a feeding unit, a follow-up cutting unit and a control unit, this utility model enables fast cutting efficiency and accurate cutting dimensions of the clay blank; the straightness of the cut clay blank is good and no deformation occurs; the cut edge of the cut clay blank is smooth and flat, and after sintering, there is no need for secondary cutting before encapsulation, thus improving work efficiency.

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-4 As shown, a ceramic flat film cutting device includes:

[0022] The feeding unit 1 includes two belt conveyors 101 spaced apart, and continuous baffles 102 are provided on the front and rear sides of the two belt conveyors 101. The baffles 102 are provided with limiting mechanisms to prevent the mud blanks 3 from deviating. The center of the drive roller of the belt conveyor 101 located at the input end is equipped with a rotary encoder for speed measurement through a coupling. The limiting mechanism includes several threaded sleeves 103 that are fixed on the baffles 102. The threaded sleeves 103 are internally threaded with screws 104. The screws 104 are provided with a handwheel 105 at one end located outside the baffles 102 and a limiting plate 106 rotatably connected at one end located inside the baffles 102. The two side walls of the threaded sleeves 103 located inside the baffles 102 are provided with connecting blocks 107. A telescopic guide rod 108 is provided between the connecting blocks 107 and the limiting plate 106.

[0023] The rotary encoder can monitor the conveying speed of the clay blank 3 in real time and feed it back to the control unit. The limit mechanism prevents the clay blank 3 from deviating during feeding, thus avoiding affecting the cutting accuracy. During the cutting process, the conveying speed of the belt conveyor 101 is 2.5~3.5m / s. Too slow a speed will affect the working efficiency, while too fast a speed will result in the cut surface flatness not meeting the requirements.

[0024] The follow-up cutting unit 2 includes a support plate 201 located at the bottom of the outer side of the baffle 102. The top of the support plate 201 is provided with a transverse linear slide 202. The top of the slider of the transverse linear slide 202 is provided with a vertical linear slide 203. A cutting beam 204 is provided between the opposing surfaces of the sliders of the two vertical linear slides 203. A blade mounting seat 205 is provided at the bottom of the cutting beam 204. A cutting blade 206 is detachably mounted on the bottom of the blade mounting seat 205. A blade groove is provided at the bottom of the blade mounting seat 205. The top of the cutting blade 206 is inserted into the blade groove and fixed by bolts. A cutting block 207 is installed between the opposing surfaces of the two baffles 102. The cutting block 207 is located in the gap between the two belt conveyors 101. A force sensor for preventing the cutting blade 206 from overcutting is embedded at the bottom of the cutting block 207.

[0025] The horizontal linear slide 202 drives the cutting blade 206 to move synchronously and in the same direction as the clay blank 3. The vertical linear slide 203 drives the cutting blade 206 to cut vertically downwards. The cutting block 207 limits the cutting depth of the cutting blade 206. The cutting speed of the cutting blade 206 is 30-50 m / s. If the cutting speed is too slow, the clay blank 3 is prone to sticking to the cutting blade 206, resulting in deformation of the clay blank 3 after cutting. If the cutting speed is too fast, the cutting blade 260 is prone to breakage after hitting the cutting block 207.

[0026] The control unit is connected to two belt conveyors 101, a rotary encoder, and a follow-up cutting unit 2. It is used to start the follow-up cutting unit 2 when the clay blank 3 reaches 70-100mm before the set cutting length, so that the cutting blade 206 moves at the same speed and in the same direction as the clay blank 3 and completes the cutting.

[0027] The control unit can employ a conventional industrial PLC (Programmable Logic Controller, such as Siemens SIMATIC S7-1200) or a microcontroller control system (such as STMicroelectronics STM32F407ZGT6 as the main control chip). It receives signals from the rotary encoder, processes them internally, and outputs commands to drive the servo motors of the horizontal linear slide 202 and the vertical linear slide 203, respectively. Simultaneously, it communicates with a touchscreen or host computer to achieve functions such as setting the cutting length, adjusting the speed, and providing fault alarms. The above control method is a mature existing technology, and its specific circuit details will not be elaborated in this embodiment.

[0028] After cutting, the straightness and flatness of the clay blank 3 are checked: a straightedge is placed against the length direction or the cut of the clay blank 3, and the gap between the clay blank 3 and the straightedge is measured with a feeler gauge. The straightness of the clay blank 3 should be ≤0.8mm, and the flatness of the cut should be ≤0.3mm.

[0029] In operation, this invention uses a rotary encoder to measure the speed of the belt conveyor 101 (the speed of the clay blank 3 is 2.5 m / s), facilitating the calculation of the clay blank 3's moving distance based on time and speed. After a certain period, when the clay blank 3 is about 70-100 mm before reaching the set cutting length, the cutting blade 206, driven by the transverse linear slide 202, moves in the same direction and at the same speed as the clay blank 3. Simultaneously, the cutting blade 206 also moves downwards under the drive of the vertical linear slide 203 (the cutting speed of the cutting blade 206 is 35 m / s). When the length of the clay blank 3 (the required length of the cut clay blank 3 is 700mm ± 0.5mm) meets the cutting requirements, the cutting blade 206 rapidly cuts the clay blank 3 under the combined action of the horizontal linear slide 202 and the vertical linear slide 203. When the cutting blade 206 contacts the cutting stop block 207, the force sensor monitors the force on the cutting stop block 207. When the force reaches the threshold, a stop signal is triggered. The control unit controls the cutting blade 206, the horizontal linear slide 202, and the vertical linear slide 203 to return to their initial positions to start the next cut. The lengths of all ten cut clay blanks 3 meet the requirements, the straightness of the clay blank 3 is 0.4-0.6mm, and the flatness of the cut surface is 0.1-0.2mm. After sintering, the encapsulation operation can be carried out directly without any glue leakage.

[0030] This invention, by setting up a feeding unit 1, a follow-up cutting unit 2, and a control unit, enables the clay blank 3 to be cut quickly and with precise cutting dimensions; the clay blank 3 has good straightness after cutting and no deformation occurs; the cut surface of the clay blank 3 is smooth and flat after cutting, and it can be packaged without secondary cutting after sintering, thus improving work efficiency.
