Description

Technical Field

[0001] The present invention belongs to the field of fabric treatment, and particularly relates to a fabric cutting device with a coolable cutter head. Background Art

[0002] After the fabric is manufactured by the fabric manufacturer, the fabric is usually in a roll shape. Subsequently, in order to enable the fabric to be applied to different positions, it is necessary to cut the fabric so that the fabric is cut into different shapes. A fabric cutting device is a device used to cut the fabric, and it usually includes a cutting cutter head. During the process of cutting the fabric with the cutter head, the cutter head will penetrate the fabric at a very high speed, thereby achieving the disconnection of the fabric. However, during the process of the cutter head highly penetrating the fabric, the cutter head will inevitably rub against the fabric, causing the cutter head to heat up.

[0003] When the cutter head gets hot, during the process of cutting the fabric, the cutter head will have phenomena such as sticking to the fabric, and the performance of the cutter head will also decline accordingly. Therefore, it is essential to cool the cutter head. However, since the cutter head is in a high-speed working state, when using conventional means to cool the cutter head, it will inevitably affect the working efficiency of the cutter head.

[0004] In summary, the prior art has the problem that the cooling of the cutter head leads to a reduction in the working efficiency of the cutter head. Summary of the Invention

[0005] The present invention provides a fabric cutting device with a coolable cutter head, aiming to solve the problem that the working efficiency of the cutter head is reduced due to the cooling of the cutter head.

[0006] To achieve the above object, the present invention provides a fabric cutting device with a coolable cutter head, including a first working surface and a second working surface for placing the fabric. A working groove is provided between the first working surface and the second working surface, and the working groove is used for the cutter head to pierce the fabric, and the cutter head can enter the working groove.

[0007] A cooling cavity is installed in the working groove, and air holes are provided in the cooling cavity. The air holes are used to release cooling air flow in the cooling cavity, and the cooling cavity is configured with an inlet for the cutter head to enter.

[0008] In this solution, the fabric is placed at the first working surface and the second working surface for cutting. The working groove between the first working surface and the second working surface can allow the cutter head to be inserted, so that the fabric is cut. At the same time, in this solution, a cooling cavity is provided inside the working groove. When the cutter head enters the working groove during fabric cutting, the cooling air flow inside the cooling cavity can cool the cutter head. By this way, the cooling of the cutter head will not affect the cutting of the fabric by the cutter head.

[0009] Further, to ensure that the cooling air flow can enter the cooling cavity evenly, so that the tool tip can be cooled effectively by the cooling air flow at different positions in the cooling cavity. This solution includes a cooling chamber, which is connected to the cooling cavity. The cooling chamber is used to rectify the cooling air flow. In this solution, the cooling air flow first enters the cooling chamber, and then is rectified and mixed in the cooling chamber to make the cooling air flow in a uniform state. Then the cooling air flow is introduced into the cooling cavity to ensure that the tool tip can achieve a better cooling effect at different positions in the cooling cavity.

[0010] Further, since the tool tip can be inserted into the interior of the cooling cavity from different positions, to ensure that the cooling air flow can cool the tool tip when the tool tip is at different positions. In this solution, a plurality of air holes are provided in the cooling cavity, and the air holes are arranged along the length direction of the cooling cavity. In this solution, the plurality of air holes are evenly arranged inside the cooling cavity, and each air hole can discharge the cooling air flow, so that there is cooling air flow at different positions in the cooling cavity. When the tool tip is inserted into the interior of the cooling cavity from different positions, the tool tip can be cooled by the cooling air flow.

[0011] Further, to realize the supply of the cooling air flow, this solution preferably configures the cooling cavity with a connecting part, and the connecting part is used to communicate with the cooling device. In this solution, the cooling chamber is communicated with the cooling device through the connecting part, and the cooling device can generate the cooling air flow, and the cooling air flow can enter the cooling chamber.

[0012] At the same time, since the cooling air flow enters the interior of the cooling chamber from the cooling end of the cooling chamber, to ensure that the cooling air flow is evenly distributed in the cooling cavity, this solution preferably includes a cooling end and a closed end in the cooling cavity, and the diameter of the air hole gradually increases from the cooling end to the closed end. In this solution, since the diameter of the air hole gradually increases from the cooling end to the closed end, when the cooling air flow circulates in the cooling chamber, by expanding the air hole, the cooling air flow entering the interior of the cooling cavity is evenly distributed at the cooling end and the closed end, and the cooling air flow inside the cooling cavity is evenly distributed, ensuring that the tool tip can achieve a better cooling effect at different positions.

[0013] Further, to achieve a better rectification effect, this solution includes a rectification chamber. The cooling chamber and the cooling cavity are communicated through the rectification chamber, and the rectification chamber is used to rectify the cooling air flow for the second time. In this solution, a rectification chamber is provided between the cooling cavity and the cooling chamber. When the cooling air flow is discharged from the cooling chamber, there will still be an uneven problem with the cooling air flow. Therefore, this solution rectifies the cooling air flow for the second time by setting the rectification chamber, so that the cooling air flow finally reaching the interior of the cooling cavity is in a uniform state, and the uniform effect of the air flow is better.

[0014] Further, in order to support the fabric and keep it in a flat state, this solution preferably installs a material support brush in the cooling chamber. The material support brush is used to support the fabric, and the cutter head can be inserted into the material support brush. By setting the material support brush, the material support brush can support the bottom of the fabric, making the fabric in a flat state. When the fabric is in a flat state, the cutter head can accurately act on the fabric, avoiding cutting errors. At the same time, the cutter head can be inserted into the interior of the material support brush to prevent the cutter head from being damaged due to collision.

[0015] Further, when the cutter head is inserted into the interior of the material support brush, the material support brush will deform. At the same time, fabric scraps will be generated during fabric cutting. Therefore, in order to ensure that the cooling air flow can cool the cutter head when the material support brush deforms, and to accommodate the fabric scraps, this solution preferably leaves a accommodation space for the deformation of the material support brush between the side of the material support brush and the inner wall of the cooling chamber. In this solution, after the cutter head is inserted into the interior of the material support brush, the material support brush deforms into the accommodation space, forming a gap for the cooling air flow to flow inside the material support brush, ensuring that the cutter head is in contact with the cooling air flow. Compared with other setting methods, the material support brush will not deform and block the cooling air flow. At the same time, the fabric scraps generated during fabric cutting can also be accommodated in the accommodation space.

[0016] Further, since there are gaps between the two ends of the cooling chamber and the first working surface and the second working surface, in order to prevent the fabric from drilling into the gaps, this solution preferably further provides air flow holes on the side of the cooling chamber. The air flow holes are communicated with the accommodation space, and the air flow holes are used to output air flow to blow up the fabric. In this solution, the cooling air flow can enter the gaps between the cooling chamber and the first working surface and the second working surface through the air flow holes. The cooling air flow can blow the fabric so that the fabric will not drill into the gaps.

[0017] Further, in order to solve the problem that the material support brush blocks the cooling air flow and the cutter head, this solution preferably constructs the material support brush with flow holes for the cooling air flow to flow into the material support brush. In this solution, the cooling air flow can pass through the material support brush through the flow holes, enabling the cooling air flow to flow freely and preventing the cooling air flow from being blocked by the material support brush. The cooling air flow can enter the interior of the material support brush through the flow holes, and the cutter head contacts the cooling air flow inside the material support brush, and the cutter head is cooled.

[0018] In order to replace the material support brush after it has been used for a period of time, this solution preferably installs the material support brush detachably inside the cooling chamber. In this solution, the material support brush is detachably installed. When the material support brush needs to be replaced, the material support brush can be taken out from the interior of the cooling chamber.

[0019] Further, in order to move the fabric, in this solution, it is preferred that the first working surface is the upper surface of the first conveyor belt, and the first conveyor belt can drive the fabric to move. When the fabric contacts the first conveyor belt in this solution, the fabric can be driven by the first conveyor belt, causing the fabric to move.

[0020] In order to move the fabric, in this solution, it can also be preferred that the second working surface is the upper surface of the second conveyor belt, and the second conveyor belt can drive the fabric to move. When the fabric contacts the second conveyor belt in this solution, the fabric can be driven by the second conveyor belt, causing the fabric to move.

[0021] The beneficial effect of the present invention is that: in this solution, the fabric is placed at the first working surface and the second working surface for cutting. The working groove between the first working surface and the second working surface can allow the tool head to be inserted, so that the fabric can be cut. At the same time, in this solution, a cooling cavity is provided inside the working groove. When the tool head cuts the fabric and enters the working groove, the cooling air flow inside the cooling cavity can cool the tool head. In this way, the cooling of the tool head will not affect the cutting of the fabric by the tool head. Description of the Drawings

Detailed Description of the Embodiments

[0028] In order to make the purpose, technical solutions and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Embodiment 1

[0030] Basically as shown in the appended Figure 1 to the appended Figure 3 As shown, a fabric cutting device with a coolable cutter head includes a first conveyor belt 1, a second conveyor belt 2, and a frame 8. The frame 8 includes two left and right mounting plates, and a cross beam is further provided between the mounting plates on both sides. A cross movement mechanism 5 is mounted on the cross beam. The cross movement mechanism 5 can be a lead screw mechanism. When the lead screw of the cross movement mechanism 5 rotates, the slider mounted on the lead screw slides. A telescopic cylinder 6 is fixedly mounted at the bottom of the slider. The telescopic cylinder 6 can extend and retract, thereby driving the cutter head 7 to move up and down. The cutter head 7 is fixedly mounted on the telescopic cylinder 6. The cutter head 7 is specifically a cutting cutter head 7 in the prior art, and its structure will not be elaborated in this embodiment. In addition, the cross movement mechanism 5 for driving the cutter head 7 to move horizontally can also be replaced with other structures in the prior art; the telescopic cylinder 6 for driving the cutter head 7 to move down can also be replaced with other structures in the prior art.

[0031] In this embodiment, both ends of the first conveyor belt 1 and the second conveyor belt 2 are respectively mounted on the mounting plates. The first conveyor belt 1 and the second conveyor belt 2 can be specifically mounted on the frame 8 through fasteners. Since both ends of the first conveyor belt 1 and the second conveyor belt 2 are fixedly mounted on the frame 8, the frame 8 fixes the positions of the first conveyor belt 1 and the second conveyor belt 2, so that the first conveyor belt 1 and the second conveyor belt 2 are in a cooperative state.

[0032] The first conveyor belt 1 and the second conveyor belt 2 of this embodiment are arranged in a front-back arrangement, and the conveying directions and conveying speeds of the first conveyor belt 1 and the second conveyor belt 2 are exactly the same. The upper surface of the first conveyor belt 1 is the first working surface, and the upper surface of the second conveyor belt 2 is the second working surface. The first working surface and the second working surface are on the same horizontal plane. The fabric can be placed on the first working surface and the second working surface, and the fabric is in a flat state. And when the first conveyor belt 1 and the second conveyor belt work, the fabric is driven forward by the first conveyor belt 1 and the second conveyor belt.

[0033] The first conveyor belt 1 and the second conveyor belt 2 of this embodiment have exactly the same structure. The first conveyor belt 1 and the second conveyor belt 2 both include a driving roller, a driven roller, a conveyor belt, and a driving motor. The driving roller and the driven roller are respectively arranged at two ends. A conveyor belt is wound around between the driving roller and the driven roller. The conveyor belt can be a rubber belt. The driving roller is in transmission connection with the driving motor. When the driving motor works, the driving roller can rotate. When the driving roller rotates, it drives the conveyor belt and the driven roller to move, and drives the fabric located on the conveyor belt forward. Of course, it can be understood that the structure of the conveyor belt can be various, and the conveyor belts used for conveying fabrics in the prior art can all be applied to this embodiment, and this embodiment will not elaborate on this.

[0034] In this embodiment, the first conveyor belt 1 and the second conveyor belt 2 are arranged at intervals, so that a working groove is formed between the first conveyor belt 1 and the second conveyor belt 2. The cutter head 7 is specifically located directly above the working groove. When the cutter head 7 descends driven by the telescopic cylinder 6, the cutter head 7 contacts the fabric on the first conveyor belt 1 and the second conveyor belt 2 and cuts the fabric. At the same time, when it is necessary to cut fabrics at different positions, the transverse movement mechanism 5 can drive the cutter head 7 to move transversely, so that the cutter head 7 is located at different positions. After the fabric is cut by the cutter head 7, the telescopic cylinder 6 drives the cutter head 7 to move upward, and then the fabric can be driven by the first conveyor belt 1 and the second conveyor belt 2 to continue to move forward.

[0035] In order to cool the cutter head 7, a cooling component 3 is arranged in the working groove in this embodiment. The cooling component 3 is a profile and is integrally formed to ensure airtightness. At the same time, the integrally formed cooling component 3 will not have local deformation, ensuring that the cooling component 3 can stably cooperate with the first conveyor belt 1 and the second conveyor belt 2 in the working groove and preventing the cooling component 3 from affecting the normal operation of the first conveyor belt 1 and the second conveyor belt 2. The two ends of the cooling component 3 are open, and bolt connection ports are arranged at the ends of the cooling component 3. The bolt connection ports cooperate with bolts to install the cooling component 3 on the mounting plate. The two ends of the cooling component 3 are blocked by the mounting plate, and the cooling component 3 is integrally closed to prevent leakage of the cooling air flow.

[0036] As Figure 3 shown, the cooling component 3 in this embodiment specifically includes a cooling chamber 33, a rectifying chamber 32 and a cooling cavity 31. The cooling chamber 33 is arranged at the bottommost, and a connecting part 35 is configured at the end of the cooling chamber 33. The connecting part 35 is a connecting joint, and the connecting joint can be adapted to a pipeline, so that the inside of the cooling chamber 33 is communicated with the pipeline. The connecting joint can be any one of the joints connecting to the pipeline in the prior art. For example: a water pipe joint or an air pipe joint, etc. The end of the pipeline can be connected to the outlet of the cooling device, so that the cooling air flow generated by the cooling device can enter the cooling chamber 33. The cooling device in this embodiment can be an air-conditioning compressor, and the air-conditioning compressor can output low-temperature gas. The cooling device can also be a blower, and the blower can output normal-temperature cooling air flow.

[0037] When the cooling air flow enters the inside of the cooling chamber 33, the cooling air flow is contained in the cooling chamber 33, and the cooling air flow is mixed in the cooling chamber 33, and the cooling air flow is rectified for the first time, so that the cooling air flow is evenly mixed in the cooling chamber 33.

[0038] In this embodiment, the rectifying cabin 32 is located above the cooling cabin 33. The rectifying cabin 32 and the cooling cabin 33 are separated from each other by a blocking part 34, and a connection port is formed on the blocking part 34, so that the rectifying cabin 32 and the cooling cabin 33 can communicate with each other. In this embodiment, a plurality of connection ports are provided, and the connection ports are evenly arranged along the length direction of the cooling component 3, and the connection ports are arranged in a linear arrangement. Since the connecting part is located at one end of the cooling cabin 33, the other end of the cooling cabin 33 is closed. Therefore, in this embodiment, the diameter of the connection port gradually expands from the connecting part 35 to the other end of the connecting part 35. By setting the diameters of the connection ports to be different at different positions, the cooling air flow can enter the rectifying cabin 32 more evenly, and the air flow is more evenly distributed in the rectifying cabin 32.

[0039] In this embodiment, the cooling cavity 31 is located above the rectifying cabin 32, and the cooling cavity 31 and the rectifying cabin 32 are communicated through air holes. A plurality of air holes are also provided, and the air holes are arranged in a linear arrangement along the length direction of the cooling component 3. The cooling air flow is mixed for the first time in the cooling cabin 33, and then mixed for the second time in the rectifying cabin. Finally, after the air flow enters the cooling cavity 31, the cooling air flow is in a uniformly distributed state inside the cooling cavity 31, ensuring that the tool head 7 can be cooled by the cooling air flow when the tool head 7 is inserted into different positions of the cooling cavity 31, and the cooling effect of the tool head 7 is better, avoiding the phenomenon that there is no cooling air flow in contact with the tool head 7.

[0040] In this embodiment, the diameter of each air hole is different, and the diameter of the air hole gradually expands from the cooling end to the closed end, so that the cooling air flow in the rectifying cavity 32 also enters the cooling cabin more evenly. The cooling end is the end where the connecting part is provided, and the closed end is the opposite end of the cooling end.

[0041] As Figure 3 shown, in this embodiment, the cooling cavity 31 is a semi-closed chamber, and the cooling cavity 31 can confine the cooling air flow inside the cooling cavity 31 to ensure that the cooling air flow does not freely diffuse. At the same time, an inlet for the tool head 7 to enter the cooling cavity 31 is provided at the top of the cooling cavity 31. In this embodiment, when the tool head 7 pierces the fabric, the lower end of the tool head 7 enters the cooling cavity 31 from the inlet. At this time, the cooling air flow confined inside the cooling cavity 31 can cool the tool head 7. In this embodiment, since the cooling air flow is confined inside the cooling cavity 31, the cooling air flow does not freely diffuse, and the cooling effect of the tool head 7 is better.

[0042] As Figure 3As shown, since the ends of the first conveyor belt 1 and the second conveyor belt 2 are both arc-shaped, there will inevitably be a certain gap at the ends of the first conveyor belt 1 and the second conveyor belt 2. Therefore, in order to prevent the cutter head 7 from sagging at the end position of the conveyor belt, in this embodiment, fitting parts 36 are preferably provided on both sides of the cooling component 3 respectively. The fitting parts 36 extend towards the end of the conveyor belt to fill the gap at the end of the conveyor belt, so that the fabric is supported by the fitting parts 36. The bottom end of the fitting part 36 is preferably arc-shaped, so that the fitting part 36 can fit with the end of the conveyor belt, avoiding too large a gap between the end of the conveyor belt and the cooling component 3 and preventing the fabric from getting into the gap.

[0043] Meanwhile, in order to ensure that the fabric can move smoothly on the tops of the first conveyor belt 1, the second conveyor belt 2 and the cooling component 3. In this embodiment, it is preferred that the tops of the first conveyor belt 1, the second conveyor belt 2 and the cooling component 3 are all preferably in the same plane. This enables the fabric to move without being hindered.

[0044] Embodiment 2

[0045] This embodiment is an improvement based on Embodiment 1, as Figure 4 and Figure 5 shown. In this embodiment, in order to solve the problem of the fabric sagging at the working groove and avoid the cutter head 7 being unable to accurately process the fabric due to the sagging of the fabric. In this embodiment, a material support brush 4 is installed in the cooling cavity 31. The top of the material support brush 4 is slightly lower than the first plane and the second plane, and inclined surfaces are provided on both sides of the opening and inclined towards the material support brush, so that the fabric can move smoothly on the first plane, the second plane and the top of the material support brush.

[0046] As Figure 4 shown, in order to enable the material support brush 4 to be installed inside the cooling cavity 31, in this embodiment, limiting protrusions are provided on the inner wall of the cooling cavity 31. The material support brush 4 includes flexible bristles and a base. The top of the base contacts the limiting protrusions, so that the material support brush 4 is stably installed inside the cooling cavity 31. At the same time, the base can be separated from the limiting protrusions by sliding, so that the material support brush 4 can be taken out from inside the cooling cavity 31 to realize the replacement of the material support brush 4.

[0047] In this embodiment, in order to prevent the material support brush 4 from obstructing the contact between the cooling air flow and the cutter head 7, a plurality of flow holes 41 are uniformly provided on the mounting seat. When the cooling air flow enters the inside of the cooling cavity 31, the cooling air flow inside the cooling cavity 31 can enter the inside of the material support brush 4 through the flow holes 41. At the same time, since after the cutter head 7 pierces the fabric, the cutter head 7 is inserted into the inside of the material support brush 4. Therefore, the cutter head 7 can contact the cooling air flow inside the material support brush 4 to cool the cutter head 7.

[0048] As Figure 4 and Figure 5 shown, in this embodiment, the material support brush 4 is installed inside the cooling chamber 31, but the side of the material support brush 4 does not contact the inner wall of the cooling chamber 31. There is a receiving space between the material support brush 4 and the inner wall of the cooling chamber 33 in this embodiment. When the tool head 7 is inserted into the material support brush 4, the material support brush 4 deforms outward, and the material support brush 4 can bend into the receiving spaces on both sides. Through the above design, when the material support brush 4 shifts into the receiving space, several gaps will be formed inside the material support brush 4, avoiding the bent material support brush 4 from obstructing the flow of the cooling air flow. The cooling air flow flows along the gaps and contacts the tool head 7 to achieve the cooling of the tool head 7. In addition, the cloth scraps cut by the tool head can also be accommodated in the receiving space, so that the cloth scraps will not fly around, avoiding the cloth scraps from interfering with the tool head.

[0049] Embodiment 3

[0050] This embodiment is improved on the basis of Embodiment 2. This embodiment further includes air flow holes 37, which are located at the left and right ends of the cooling component 3. The air flow holes 37 are in communication with the receiving space. The outlet of the air flow holes 37 is located in the connection gap between the cooling component 3 and the first conveyor belt 1 and the second conveyor belt 2. When the cooling air flow enters the receiving space, the cooling air flow will then enter the connection gap between the cooling component 3 and the first conveyor belt 1 and the second conveyor belt 2 through the air flow holes 37. Therefore, when the cloth moves through the connection gap between the cooling component 3 and the first conveyor belt 1 and the second conveyor belt 2, the cooling air flow can blow up the cloth, so that the cloth will not sag, avoiding the cloth from getting into the connection gap between the cooling component 3 and the first conveyor belt 1 and the second conveyor belt 2.

[0051] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
