Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to an extrusion cutting device for modified plastic production. Background Technology

[0002] Modified plastics refer to plastic products that have been modified from general-purpose plastics and engineering plastics through methods such as filling, blending, and reinforcement, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. With the significant improvement of people's living standards and the advancement of technology, "replacing steel with plastics" and "replacing wood with plastics" will become a trend in China. As an important component in the field of new chemical materials, modified plastics can significantly improve the strength, hardness, toughness, flame retardancy, and cold resistance of ordinary plastics, which often have their own characteristics and defects.

[0003] Currently, in the processing of modified plastics, it is usually necessary to heat and extrude the material, and then cut it after extrusion. Existing cutting devices typically use a cylinder to drive the cutter for downward cutting. However, under some production requirements, the current cutting device cannot easily adjust the cutting length. In addition, after long-term use, the blade surface is prone to dulling, which affects the flatness of the cut surface. The common solution is to disassemble the blade for maintenance, which not only greatly reduces work efficiency but also requires a long downtime, seriously affecting the continuity of production.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an extrusion cutting device for the production of modified plastics. The extrusion cutting device for the production of modified plastics includes a conveying component 100 and a cutting component 200. The conveying component 100 facilitates the heating and extrusion conveying of the modified plastics, while the cutting component 200 facilitates the cutting of the molded plastics and can automatically grind and maintain the blade surface, reducing the cumbersome nature of traditional maintenance work.

[0031] The conveying assembly 100 includes a base plate 101, a conveying shell 102, a conveying component 103, a discharge pipe 104, and a feed inlet 105. The conveying shell 102 is fixed to the top of the base plate 101, the conveying component 103 is fixed to one side of the conveying shell 102, the discharge pipe 104 is fixed to one side of the conveying shell 102, and the feed inlet 105 is fixed to one side of the top of the conveying shell 102.

[0032] The conveyor shell 102 is secured to the base plate 101 via a support plate. The conveyor 103 facilitates the spiral extrusion conveying of the plastic material inside the conveyor shell 102. The discharge pipe 104 is detachably installed at one end of the conveyor shell 102 for easy replacement and maintenance. A discharge hole is also provided on one side of the discharge pipe 104 to facilitate the molding and extrusion of the extruded plastic. The inlet 105 allows workers to accurately pour the plastic into the interior of the conveyor shell 102.

[0033] The cutting assembly 200 is disposed on one side of the top of the base plate 101 and includes a support frame 201, a grinding component 202, a support platform 203, a fixing plate 204, and a cutting component 205. The support frame 201 is fixed to one side of the top of the base plate 101, the grinding component 202 is disposed at the bottom of the support platform 203, the support platform 203 is disposed inside the support frame 201, the fixing plate 204 is fixed to one side of the support frame 201, and the cutting component 205 is fixed to one side of the fixing plate 204.

[0034] The support frame 201, in conjunction with the fixing plate 204, facilitates the support and fixation of the cutting part 205. The grinding part 202 is located at the bottom of the support platform 203. After the support platform 203 is flipped, it is convenient to grind the blade surface, thereby improving the sharpness of the blade surface. The support platform 203 facilitates the support and fixation of the grinding part 202 and assists in material conveying. The cutting part 205 facilitates the continuous cutting of the extruded plastic, thereby improving the efficiency of modified plastic processing.

[0035] Example 2

[0036] Reference Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the conveying component 103 includes a servo motor 103a, an output rod 103b, and a spiral blade 103c. The servo motor 103a is fixed to one side of the conveying housing 102, and its output end is fixedly connected to the output rod 103b. One end of the output rod 103b extends into the interior of the conveying housing 102, and its surface is fixedly connected to the spiral blade 103c.

[0038] By turning on the servo motor 103a, the conveying rod 103b can drive the spiral blade 103c to rotate continuously inside the conveying housing 102, thereby extruding and conveying the modified plastic, which facilitates subsequent processing.

[0039] Specifically, the conveying assembly 100 also includes a heating box 106, a heating module 107, and a heat-conducting copper pipe 108. The heating box 106 is fixed to the front and rear sides of the conveying shell 102, the heating module 107 is fixed to both sides of the heating box 106, and the heat-conducting copper pipe 108 is fixed inside the heating box 106, with both ends electrically connected to the heating module 107.

[0040] The heating box 106 is installed on the front and rear sides of the conveying shell 102. When the modified plastic enters the interior of the conveying shell 102 and needs to be heated for extrusion molding and conveying, the heating module 107 is turned on to generate heat in the heat-conducting copper pipe 108, thereby raising the internal temperature of the conveying shell 102 and fusing the modified plastic. Then, in conjunction with the conveying component 103, the material is extruded and conveyed to facilitate the extrusion molding of the modified plastic. It should be noted that the heating module 107 usually includes electric heating elements such as resistance wires and ceramic heaters. These heating elements can generate heat when current passes through them. When current passes through the heating elements in the heat-conducting copper pipe, it releases a large amount of heat energy. Copper is a metal with very good thermal conductivity, so it can quickly conduct the heat generated by the heating elements to other parts of the copper pipe. Due to the high thermal conductivity of the copper pipe, the heat can be evenly distributed to the surrounding area of ​​the heating module. In addition, this is existing technology, so it will not be described in detail.

[0041] Specifically, the cutting assembly 200 also includes a first small DC motor 207, which is fixed to one side of the support frame 201 and its output end is fixedly connected to the support platform 203. The other side of the support platform 203 is rotatably connected to the support frame 201 through a bearing.

[0042] When the user needs to flip the support table 203 to use the grinding part 202, the first small DC motor 207 can be driven. The output end of the first small DC motor 207 drives the support table 203 to flip 90 degrees inside the support frame 201 so that the grinding part 202 is at the top, which makes it convenient to grind the blade surface.

[0043] Specifically, the cutting assembly 200 also includes a slide 208, a slide plate 209, and an auxiliary platform 210. The slide 208 is opened on one side of the bottom of the base plate 101, the slide plate 209 is inserted into the inside of the slide 208, and the auxiliary platform 210 is fixed to the top of the slide plate 209.

[0044] The auxiliary platform 210 can be easily adjusted inside the base plate 101 by means of the sliding groove 208 and the sliding plate 209. The auxiliary platform 210 can also provide auxiliary support for the cut modified plastic. At the same time, a support plate extends from the surface of the auxiliary platform 210 and can be inserted into the bottom of the support platform 203. When the support platform 203 does not need to be flipped, the auxiliary platform 210 can be pushed and inserted into the support platform 203. The support plate at the bottom of the auxiliary platform 210 will press against the bottom of the support platform 203, reducing the pressure that is borne by the output shaft of the first small motor 207 alone.

[0045] Specifically, the cutting component 205 includes a second DC motor 205a, a drive plate 205c, a connecting rod 205d, a hinge rod 205e, a positioning plate 205f, a cutter 205g, and a limiting frame 205h. The second DC motor 205a is fixed to one side of the fixed plate 204, and its output end extends through to one side of the fixed plate 204 and is fixedly connected to the drive plate 205c. The connecting rod 205d is installed on one side of the drive plate 205c through a bearing, and its bottom is hinged to the hinge rod 205e. The bottom of the hinge rod 205e is fixedly connected to the positioning plate 205f. The cutter 205g is installed inside the positioning plate 205f. The limiting frame 205h is sleeved on the surface of the hinge rod 205e, and its two sides are fixedly connected to the support frame 201.

[0046] When the user needs to cut the extruded modified plastic, the second DC motor 205a is turned on to rotate the drive disk 205c. The connecting rod 205d, which rotates on one side of the drive disk 205c, rotates eccentrically on one side of the drive disk 205c. Therefore, when the connecting rod 205d moves, it will hinge the hinge rod 205e down. As the hinge rod 205e descends, it will drive the positioning plate 205f to descend linearly within the limiting frame 205h, and cause the cutter 205g installed inside the positioning plate 205f to descend, thereby cutting the modified plastic for subsequent processing. Then, as the drive disk 205c rotates, the connecting rod 205d will drive the hinge rod 205e and the positioning plate 205f to reciprocate up and down. During this process, the operator can electrically connect the remote PCL controller to the second DC motor 205a to control the speed of the second motor 205a, thereby adjusting the rate at which the cutter 205g descends to cut modified plastic strips of different lengths.

[0047] Specifically, the cutting component 205 also includes a connecting plate 205i, a limiting rod 205j, a sliding bar 205k, and a spring 205b. The two connecting plates 205i are fixed to the top and bottom of the support frame 201, respectively. The limiting rod 205j is fixed between the two connecting plates 205i. The sliding bar 205k is slidably connected to the surface of the limiting rod 205j and is fixedly connected to the cutter 205g on one side. The spring 205b is fixed to the bottom of the sliding bar 205k and is fixedly connected to the connecting plate 205i at one end.

[0048] The connecting plate 205i facilitates the fixing of the limiting rod 205j, while the positioning plate 205f moves up and down, which also drives the sliding bar 205k to move on the surface of the limiting rod 205j, and continuously compresses and resets the spring 205b, thereby reducing the vibration when the cutter 205g moves up and down.

[0049] Example 3

[0050] Reference Figure 4 and Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the grinding component 202 includes a third small DC motor 202a, a reciprocating screw 202b, a slide rod 202c, a threaded sleeve 202d, a sliding ring 202e, a grinding stone 202f, and an extension plate 202g. The extension plate 202g is fixed to the front and rear sides of the bottom of the support platform 203. The third small DC motor 202a is fixed to one side of one of the extension plates 202g, and its output end is fixedly connected to the reciprocating screw 202b. One end of the reciprocating screw 202b is rotatably connected to the other extension plate 202g through a bearing. The slide rod 202c is fixed between the two extension plates 202g. The threaded sleeve 202d is rotatably connected to the surface of the reciprocating screw 202b. The sliding ring 202e is slidably connected to the surface of the slide rod 202c. The grinding stone 202f is fixed between the threaded sleeve 202d and the sliding ring 202e.

[0052] After the grinding part 202 is flipped on top of the support platform 203, when the cutter 205g needs to be ground, the third small DC motor 202a is turned on. The output end of the third small DC motor 202a drives the reciprocating screw 202b to rotate, and the threaded sleeve 202d drives the grinding stone 202f to move. As the grinding stone 202f moves, it causes the sliding ring 202e to move in a limited position on the surface of the slide rod 202c. Due to the threaded design of the reciprocating screw 202b, the grinding stone 202f can move back and forth continuously, thereby grinding the lower part of the blade. The cutter 205g, which descends into the polishing stone 202f, is continuously polished to ensure the sharpness of the blade surface. This reduces the frequency of maintenance and also reduces the overall downtime for maintenance of the device. It should be noted that one of the extension plates 202g, on which a third small DC motor 202a is fixed, has an additional slot inside. When the support platform 203 is flipped, the extension plate 202g will avoid the inside of the support frame 201, preventing the support platform 203 from being unable to flip smoothly due to the setting of the extension plate 202g.

[0053] Specifically, the cutting assembly 200 also includes a limiting plate 211, a fan 212, and a guide plate 213. The limiting plate 211 is fixed to both sides of the top of the support platform 203, the fan 212 is fixed to one side of the top of the discharge pipe 104, and the guide plate 213 is fixed to one side of the bottom of the discharge pipe 104.

[0054] The limiting plate 211 is fixed to both sides of the top of the support platform 203, which can limit the discharge position and prevent the modified plastic from slipping to the cutting position during discharge. It should be noted that the surface of the auxiliary platform 210 also extends a support plate, which can be inserted into the bottom of the support platform 203. When the support platform 203 does not need to be flipped, the auxiliary platform 210 can be pushed and inserted into the support platform 203. The support plate at the bottom of the auxiliary platform 210 will press against the bottom of the support platform 203, reducing the pressure borne by the output shaft of the first small motor 207 alone. The fan 212 can quickly cool the modified plastic at the discharge position, thereby facilitating the subsequent cutting work.

[0055] Specifically, the cutting assembly 200 also includes a reinforcing block 214, which is fixed to one side of the support frame 201 and its bottom is fixedly connected to the base plate 101.

[0056] By fixing the reinforcing block 214 between the base plate 101 and the support frame 201, the strength of the support frame 201 can be effectively enhanced, thereby ensuring its stability and durability after long-term use.

[0057] In use, the modified plastic is first poured into the conveying shell 102 through the feed port 105, and the heat-conducting copper pipe 108 is heated by the heating module 107. At this time, the inside of the conveying shell 102 will gradually rise, melting the modified plastic to facilitate the extrusion process. Then, by turning on the servo motor 103a, the conveying rod 103b drives the spiral blade 103c to rotate continuously inside the conveying shell 102, thereby extruding and conveying the modified plastic to the inside of the discharge pipe 104, and then discharging it through the round hole to the top of the guide plate 213 and the support platform 203. At this time, the fan 212 is turned on to cool the extruded modified plastic. Then, when it is necessary to cut the modified plastic, the second DC motor 205a is turned on to rotate the drive disk 205c. The connecting rod 205d on one side of the drive disk 205c rotates eccentrically on one side of the drive disk 205c. Therefore, when the connecting rod 205d moves, it will hinge and drive the hinge rod 205e to descend. As the hinge rod 205e descends, it will drive the positioning plate 205f to descend linearly within the limiting frame 205h. When the positioning plate 205f moves up and down, it will also drive the sliding bar 205k to move on the surface of the limiting rod 205j, and continuously compress and reset the spring 205b, thereby reducing the vibration when the cutter 205g moves up and down, and causing the cutter 205g installed inside the positioning plate 205f to descend, thereby cutting the modified plastic and facilitating subsequent processing. Then, as the drive disk 205c rotates, the connecting rod 205d will drive the hinge rod 205e to descend. The 05e and positioning plate 205f reciprocate up and down movement. During this process, the operator can electrically connect the remote PCL controller to the second DC motor 205a to control the speed of the second motor 205a, thereby adjusting the descent rate of the cutter 205g to cut modified plastic strips of different lengths. When the device stops driving and the cutter 205g needs maintenance, the auxiliary table 210 is first pulled out of the slide plate 209 from the slide groove 208, and then the first small DC motor 207 is driven. The output of the first small DC motor 207 drives the support table 203 to rotate 90 degrees inside the support frame 201. At this time, the extension plate 202g will rotate on top of the support table 203, so that the position of the grinding part 202 is in the position of At the top, the auxiliary platform 210 is reset and inserted into the support platform 203 for auxiliary positioning. Then, in conjunction with the cutting component 205, the cutter 205g descends into the grinding stone 202f. Next, the third small DC motor 202a is turned on, driving the reciprocating screw 202b to rotate via its output. This causes the threaded sleeve 202d to move the grinding stone 202f. As the grinding stone 202f moves, the sliding ring 202e moves to a limited position on the surface of the slide rod 202c. Due to the threaded design of the reciprocating screw 202b, the grinding stone 202f continuously reciprocates, continuously grinding the cutter 205g inside the grinding stone 202f to ensure the sharpness of the blade.This reduces the frequency of maintenance and also shortens the overall downtime for system maintenance.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
