Description

A thermoplastic composite material molding and cutting device Technical Field

[0001] This utility model relates to the field of thermoplastic material cutting technology, specifically a thermoplastic composite material molding and cutting strip device. Background Technology

[0002] Thermoplastic composites are composite materials composed of a thermoplastic polymer matrix and reinforcing materials (such as fibers, granules, or sheets). These materials combine the processing properties of thermoplastics with the strength, stiffness, and heat resistance of reinforcing materials. Thermoplastic composites require the use of thermoplastic molding machines for processing. A thermoplastic molding machine is a device used to inject high-temperature liquids into the molding station inside the molding machine, and then mold them after cooling. It is commonly used for molding liquid materials. Existing thermoplastic molding machines generally have molding dies that are pressed together. The molding dies are divided into upper dies and lower dies.

[0003] After the existing thermoplastic composite material is molded, it can be cut into strips or sheets that meet specific size requirements through strip cutting, so that it can be used in downstream processes or sold as a final product. However, after the thermoplastic composite material is processed in the molding machine, the molded thermoplastic products need to be manually transported to the cutting table. Due to the large production volume, manual handling will reduce production efficiency. In addition, most thermoplastic products are cut into strips with a single blade, resulting in a slow cutting speed. Summary of the Invention

The thermoplastic product can be transferred to the cutting frame through the feeding component, saving the time of manual handling.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] As shown in Figures 1-5, a thermoplastic composite material molding and slitting device includes: a molding machine 1, a support platform 101 installed inside the molding machine 1, a lower mold 102 installed on the top of the support platform 101, limiting rods 103 installed on the four sides of the top of the support platform 101, an upper mold 104 slidably connected to the limiting rods 103, a feeding assembly disposed on one side of the outer end of the molding machine 1, the feeding assembly including: a feeding table 2, a support frame 201, a rotating roller 202, a conveyor belt 203 and a servo motor 204, and a slitting assembly disposed on the outer end of the molding machine 1, the slitting assembly including: a cutting frame 3, a transmission roller 301, a fixing frame 302, a fixing plate 303, a cutting blade 304, a lifting cylinder 305 and a telescopic rod b306.

[0026] The upper mold 104 has a molding station 105 installed at the bottom, the molding machine 1 has a molding cylinder 106 installed at the top, the bottom of the molding cylinder 106 has a telescopic rod a107 installed at the output end, the bottom of the telescopic rod a107 is connected to the upper mold 104, and the upper mold 104 has a liquid injection connector 108 installed on one side of the top.

[0027] When the molding machine 1 is in use, the molding cylinder 106 is started through the control panel 601. The molding cylinder 106 drives the telescopic rod a107 to move downward, so that the telescopic rod a107 pushes the upper mold 104 downward to the lower mold 102, that is, the upper mold 104 and the lower mold 102 are closed. Thermoplastic liquid material with a high temperature is injected into the molding station 105 between the upper mold 104 and the lower mold 102 through the liquid injection port 15, so that the thermoplastic liquid material can be molded inside the upper mold 104 and the lower mold 102.

[0028] It should be noted that the internal structure of the molding machine 1 in this application is prior art in the field and has been disclosed in publication number CN218111637U "A thermoplastic molding machine with a protective structure". It is not an innovative part of this application, but a reference description part of this application. The working principle and process of the molding machine 1 and its internal structure can also be referred to that publication number, and will not be repeated here.

[0029] In this implementation plan: After the existing thermoplastic composite materials are processed in the molding machine, the molded thermoplastic products need to be manually transported to the cutting table. Due to the large production volume, manual handling will reduce production efficiency. In addition, when cutting thermoplastic products into strips, most of them are equipped with a single blade, which results in a slow cutting speed. The following is a new structure designed to solve the drawbacks of cutting thermoplastic products into strips in this application.

[0030] The forming machine 1 has a feeding platform 2 on one side of its outer end. A support frame 201 is installed at the bottom of the feeding platform 2. Rotating rollers 202 are rotatably connected to both sides of the feeding platform 2 through bearings. Multiple support rollers are rotatably connected to the middle through bearings. A conveyor belt 203 is installed on the outside of the rotating rollers 202. A servo motor 204 is installed on one side of the outer end of the feeding platform 2. The output shaft of the servo motor 204 is connected to the rotating roller 202 on one side.

[0031] After the thermoplastic liquid raw material is formed inside the upper mold 104 and the lower mold 102, the upper mold 104 is moved upward by the telescopic rod a107 driven by the forming cylinder 106, that is, the upper mold 104 and the lower mold 102 open, so that the heat inside the upper mold 104 and the lower mold 102 can be dissipated, allowing the formed thermoplastic product to dissipate heat. An external fan can also be used to blow air onto the thermoplastic product to accelerate the cooling of the thermoplastic product. After the thermoplastic product has cooled down, it is taken out of the mold and placed on the conveyor belt 203 of the feeding table 2. At this time, the servo motor 204 is started through the control panel 601. The servo motor 204 drives the rotating roller 202 to rotate, so that the rotating roller 202 drives the conveyor belt 203 to move, transferring the thermoplastic product to the cutting frame 3. This saves the time of manual handling, meets the needs of thermoplastic material forming and cutting, and improves the production efficiency of thermoplastic products.

[0032] The feeding platform 2 has a cutting frame 3 installed at its outer end. The cutting frame 3 has multiple drive rollers 301 rotatably connected to it via bearings. The drive rollers 301 are spaced at the same distance. A fixing frame 302 is installed on the top of the cutting frame 3. A fixing plate 303 is provided at the bottom of the fixing frame 302. Multiple cutting blades 304 are installed at the bottom of the fixing plate 303. The gaps between the multiple cutting blades 304 and the multiple drive rollers 301 are directly opposite. A lifting cylinder 305 is installed on the top of the fixing frame 302. A telescopic rod b306 is installed at the output end of the bottom of the lifting cylinder 305. The bottom of the telescopic rod b306 is connected to the fixing plate 303.

[0033] When the thermoplastic product is conveyed to the cutting frame 3 via the conveyor belt 203, since the cutting frame 3 is lower than the conveyor belt 203, the thermoplastic product can slide off the conveyor belt 203 onto the cutting frame 3. Multiple drive rollers 301 inside the cutting frame 3 support the thermoplastic product, positioning it at the bottom of multiple cutting blades 304. The operator can then align the thermoplastic product with the multiple cutting blades 304 to ensure a smooth cut. After aligning the thermoplastic product with the multiple cutting blades 304, the lifting cylinder 305 is activated via the control panel 601. The lifting cylinder 305 drives the telescopic rod b306 downwards, causing the telescopic rod b306 to push the fixed plate 303 and... Multiple cutting blades 304 move downwards. When the multiple cutting blades 304 come into contact with the thermoplastic product, they continuously push the fixed plate 303 and the multiple cutting blades 304 downwards, cutting the thermoplastic product under force. Since the gaps between the multiple cutting blades 304 and the multiple drive rollers 301 are directly opposite, the multiple cutting blades 304 can avoid hitting the drive rollers 301 and causing damage after cutting the thermoplastic product into strips. Moreover, the spacing between the multiple drive rollers 301 is consistent, so that the size of the strips cut from the thermoplastic product is consistent. When cutting the thermoplastic product into strips, multiple cutting blades 304 come into contact with the thermoplastic product at the same time. In conjunction with the cutting frame 3 and the multiple drive rollers 301, the cutting speed of the thermoplastic product can be accelerated.

[0034] The cutting frame 3 is equipped with a guide trough 4 at its bottom. A finished product collection box 401 is provided on one side of the bottom of the guide trough 4. After the cutting frame 3 completes the cutting of the thermoplastic product, the cut thermoplastic product will fall into the guide trough 4 through the gap between multiple transmission rollers 301. The guide trough 4 is inclined towards the finished product collection box 401, so that the strip-shaped thermoplastic product inside the guide trough 4 will slide into the finished product collection box 401, which is convenient for collecting the cut thermoplastic product.

[0035] The guide trough 4 has a filter screen 5 installed at the bottom. The bottom of the filter screen 5 is equipped with a waste collection box 501. When cutting thermoplastic products into strips, it is inevitable that debris will be generated during the cutting process. The cut thermoplastic products and the debris will fall into the guide trough 4 through the gaps between the multiple drive rollers 301. When the debris comes into contact with the filter screen 5 at the bottom of the guide trough 4, the debris will be screened off the filter screen 5 because the size of the debris is smaller than the mesh size of the filter screen 5. The debris will be screened off the cut thermoplastic products and collected in the waste collection box 501 to prevent it from falling to the ground.

[0036] The molding machine 1 has a control box 6 installed on its outer end. A control panel 601 is installed on the outside of the control box 6. The control panel 601 has a display screen and control buttons. When the molding cylinder 106, servo motor 204 and lifting cylinder 305 are in use, they are connected to the control box 6 through wires. A power cord is installed on the back of the control box 6. The other end of the power cord is equipped with a power plug. When the power plug is inserted into the socket, the control box 6, control panel 601, molding cylinder 106, servo motor 204 and lifting cylinder 305 can be powered on and used. The control panel 601 can control the molding cylinder 106, servo motor 204 and lifting cylinder 305 to start and stop. The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art. This part is not the innovation of this utility model.

[0037] Working principle:

[0038] When the molding machine 1 is in use, the molding cylinder 106 is started through the control panel 601. The molding cylinder 106 drives the telescopic rod a107 to move downward, so that the telescopic rod a107 pushes the upper mold 104 downward to the lower mold 102, that is, the upper mold 104 and the lower mold 102 are closed. Thermoplastic liquid material with a high temperature is injected into the molding station 105 between the upper mold 104 and the lower mold 102 through the liquid injection port 15, so that the thermoplastic liquid material can be molded inside the upper mold 104 and the lower mold 102.

[0039] After the thermoplastic liquid raw material is formed inside the upper mold 104 and the lower mold 102, the upper mold 104 is moved upward by the telescopic rod a107 driven by the forming cylinder 106, that is, the upper mold 104 and the lower mold 102 open, so that the heat inside the upper mold 104 and the lower mold 102 can be dissipated, allowing the formed thermoplastic product to dissipate heat. An external fan can also be used to blow air onto the thermoplastic product to accelerate the cooling of the thermoplastic product. After the thermoplastic product has cooled down, it is taken out of the mold and placed on the conveyor belt 203 of the feeding table 2. At this time, the servo motor 204 is started through the control panel 601. The servo motor 204 drives the rotating roller 202 to rotate, so that the rotating roller 202 drives the conveyor belt 203 to move, transferring the thermoplastic product to the cutting frame 3. This saves the time of manual handling, meets the needs of thermoplastic material forming and cutting, and improves the production efficiency of thermoplastic products.

[0040] When the thermoplastic product is conveyed to the cutting frame 3 via the conveyor belt 203, since the cutting frame 3 is lower than the conveyor belt 203, the thermoplastic product can slide off the conveyor belt 203 onto the cutting frame 3. Multiple drive rollers 301 inside the cutting frame 3 support the thermoplastic product, positioning it at the bottom of multiple cutting blades 304. The operator can then align the thermoplastic product with the multiple cutting blades 304 to ensure a smooth cut. After aligning the thermoplastic product with the multiple cutting blades 304, the lifting cylinder 305 is activated via the control panel 601. The lifting cylinder 305 drives the telescopic rod b306 downwards, causing the telescopic rod b306 to push the fixed plate 303 and... Multiple cutting blades 304 move downwards. When the multiple cutting blades 304 come into contact with the thermoplastic product, they continuously push the fixed plate 303 and the multiple cutting blades 304 downwards, cutting the thermoplastic product under force. Since the gaps between the multiple cutting blades 304 and the multiple drive rollers 301 are directly opposite, the multiple cutting blades 304 can avoid hitting the drive rollers 301 and causing damage after cutting the thermoplastic product into strips. Moreover, the spacing between the multiple drive rollers 301 is consistent, so that the size of the strips cut from the thermoplastic product is consistent. When cutting the thermoplastic product into strips, multiple cutting blades 304 come into contact with the thermoplastic product at the same time. In conjunction with the cutting frame 3 and the multiple drive rollers 301, the cutting speed of the thermoplastic product can be accelerated.
