Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat preservation conveying, in particular to a thick sheet shearing heat preservation conveying device. BACKGROUND

[0002] In the processing industry of plastic, rubber and other polymer materials, the extruder is one of the core production equipment. In order to facilitate storage and transportation, part of the materials need to be compressed into dense columnar blocks in advance, and when used later, the material blocks need to be cut into sheet-shaped pieces of appropriate size through thick sheet shearing process, and then broken into particles by a granulator which can be directly used by the extruder. In this process, the material blocks need to be heated to a specific temperature before shearing to reduce hardness, and then stably conveyed to the shearing station by a heat preservation conveying device. During the compression molding or storage process, the surface of the material block may be attached with loose waste or debris. When the existing conveying device is used for heat preservation and transportation, these wastes are easy to fall off due to vibration or friction and accumulate in the conveying roller, guide rail or heat preservation cavity. Long-term accumulation not only pollutes the subsequent materials, but also may cause mechanical transmission components to be blocked, which requires frequent shutdown for cleaning, seriously affecting production efficiency. Moreover, the existing heat preservation conveying device cannot quickly position the center of the material for processing, which leads to the need for re-centering during shearing and the inability to quickly adjust the position of the material block when connecting the shearing machine. It is difficult to gradually advance the material block for thick sheet shearing. In addition, the conveying device does not integrate the material compression function, and the material block is easy to displace or vibrate under the action of shearing force during the shearing process. This instability directly leads to quality problems such as the decline of shearing surface flatness and the deviation of the cutting edge. At the same time, it aggravates the abnormal wear of the cutting tool and shortens the service life of the key components. SUMMARY

DETAILED DESCRIPTION

[0026] The specific embodiment of the present application is further described in detail below in combination with the accompanying drawings.

[0027] By Figures 1 to 8The system includes a base 1, a conveyor shell 2 fixedly connected to the upper end of the base 1, an insulation shell 3 fixedly connected to the upper end of the conveyor shell 2, multiple conveyor rollers 4 evenly distributed and synchronously rotating in the left-right direction inside the conveyor shell 2, a rotatable bidirectional lead screw 5 on the front side of the conveyor shell 2, a slide rod 6 fixedly connected to the rear side of the conveyor shell 2, a cleaning plate 7 slidably connected to the front side of the slide rod 6, the lower end of the cleaning plate 7 can contact the lower side wall of the conveyor shell 2, and the front end of the cleaning plate 7 can be threadedly connected to the bidirectional lead screw 5. A connecting plate 8 is fixedly connected to the right side of the insulation shell 3. A progressive component is provided above the receiving plate 8, which can drive the material block to move forward step by step. A pressing component is provided on the right side of the progressive component, which can press the material block tightly during shearing. An installation plate 9 is fixedly connected to the middle of the conveying shell 2. A material distribution component is provided on the upper side of the installation plate 9. The material distribution component can stop the material on the conveying roller 4 and release it one by one at the same time interval. A tilting plate 10 is fixedly connected to the upper side wall of the insulation shell 3, located between the material distribution component and the progressive component. The tilting plate 10 can contact the passing material block and tilt it.

[0028] like Figures 1 to 8 As shown, a bidirectional lead screw 5, a slide bar 6, and a cleaning plate 7 are configured. The rotation of the bidirectional lead screw 5 drives the cleaning plate 7 to reciprocate along the slide bar 6. The cleaning plate 7 contacts the lower side wall of the conveyor shell 2 to remove fallen waste and debris, automatically cleaning up waste and avoiding the accumulation of contaminated material or jamming of transmission components, reducing downtime maintenance frequency, and improving production efficiency. A progressive component is set up to work in conjunction with the shearing machine to realize the step-by-step advancement of material blocks, improving shearing accuracy and efficiency. A clamping component is set up to suppress material displacement or vibration caused by shearing force, ensuring cut flatness and reducing tool wear. A material distribution component is set up, which is installed on the mounting plate 9 in the middle of the conveyor shell 2. By stopping and timed release, the material interval is controlled to ensure that the material blocks are released at intervals, realizing automatic center positioning before shearing. An insulation shell 3 is set up. The conveyor shell 2 is covered to maintain a suitable temperature for the material, resulting in a uniform reduction in material hardness, which is beneficial for consistent shearing quality and avoids breakage during shearing due to excessive hardness. Multiple synchronous conveyor rollers 4 are set to ensure stable material transport. The cleaning plate 7 and the bidirectional lead screw 5 work together to solve the problem of waste accumulation and reduce maintenance costs. The material distribution component achieves automatic center positioning, shortening the shearing preparation time. The progressive component matches the shearing rhythm to improve production capacity. The pressing component is integrated at the end of the conveyor to optimize shearing stability. Waste troughs are set on the left and right sides of the lower end of the conveyor shell 2, respectively. The waste troughs are located at the limit of the left and right movement of the cleaning plate. Two waste boxes are slidably connected to the left and right sides of the lower end of the conveyor shell 2, and the waste boxes are connected to the waste troughs on their corresponding sides for storing waste.

[0029] The conveying roller 4 is fixedly connected to the front and rear sides with drive wheels 11 respectively. Multiple drive wheels 11 on the same side are connected by a drive chain 12. A rotating wheel 13 is provided below the leftmost conveying roller 4. The rotating wheel 13 is rotatably connected to the conveying shell 2. The rotating wheel 13 is connected to the leftmost drive wheel 11 via a drive belt 14. A bevel gear is fixedly connected to the front end of the rotating wheel 13. A helical gear that can mesh with the bevel gear is fixedly connected to the left end of the bidirectional lead screw 5.

[0030] like Figures 2 to 3 As shown, the transmission wheel 11 and transmission chain 12 are set to ensure that all conveying rollers 4 rotate synchronously, ensuring smooth material conveying and avoiding slippage or deviation. The rotating wheel 13, transmission belt 14, bevel gear and helical gear are set to transmit the power of the conveying rollers 4 to the bidirectional screw 5 through the meshing of the bevel gear and helical gear, driving the cleaning plate 7 to move, realizing the linkage of conveying and cleaning without the need for an additional power source. The left conveying roller 4 is connected to an external motor to ensure that all conveying rollers 4 can rotate normally and synchronously. The rotation of the bidirectional screw 5 drives the cleaning plate 7 to move back and forth, scraping off the fallen debris and preventing waste from accumulating and contaminating the material or jamming the conveying rollers 4.

[0031] A heating plate 15 is fixedly connected to the rear side of the conveying shell 2. A plurality of heating rods 16 corresponding to the conveying rollers 4 are fixedly connected to the front end of the heating plate 15. The heating rods 16 are inserted into the conveying rollers 4 on their corresponding sides. Trapezoidal positioning frames 17 are fixedly connected to the front and rear sides of the heat preservation shell 3 respectively.

[0032] like Figure 3 As shown, a heating plate 15 is fixed to the rear side of the conveying shell 2 and is connected to an external heater. The heating rod 16 extending from its front end is inserted into each conveying roller 4. This design allows the heating rod 16 to directly contact the conveying roller 4, achieving efficient heat conduction. The rotation of the conveying roller 4 drives the heat to be evenly distributed, preventing the material from becoming too hard in some areas and causing shearing and cracking. The positioning frame 17 is set to facilitate the center positioning of the material block, ensuring that it does not deviate from the conveyor.

[0033] The advancing component includes a sleeve rod 18, with mounting brackets 19 fixedly connected to the left and right sides of the sleeve rod 18 respectively. The upper end of the mounting brackets 19 is fixedly connected to the insulation shell 3. A limit groove 20 is opened on the lower side of the sleeve rod 18. A rotatable lead screw 21 is provided inside the sleeve rod 18. A moving ring 22 is threadedly connected to the outer wall of the lead screw 21. A push rod 23 is fixedly connected to the lower end of the moving ring 22. The push rod 23 can drive the material block located on the connecting plate 8 to advance.

[0034] like Figures 2 to 7As shown, a sleeve rod 18 is set as the main support structure, and the left and right sides are fixed to the insulation shell 3 by mounting brackets 19 to provide stable support. A limiting groove 20 is set on the lower side of the sleeve rod 18 to limit the rotational freedom of the moving ring 22, ensuring that it can only move along the axial direction of the lead screw 21. At the same time, it can ensure that when the lead screw 21 rotates forward, the push rod 23 is in a vertical state, which is convenient for contacting the material block and driving it to move. When the lead screw 21 rotates in reverse, the push rod 23 is in a horizontal state, which prevents the push rod 23 from contacting the material block when it moves to the left during the return stroke, thus preventing the material block from moving onto the connecting plate 8. To prevent mechanical damage, a moving ring 22 is threadedly connected to the lead screw 21, with a push rod 23 fixed at its lower end. This ring moves horizontally as the lead screw 21 rotates, pushing the material block forward step by step. The push rod 23 directly contacts the material block, transmitting the linear motion of the moving ring 22 to the material for precise feeding. The threaded transmission between the lead screw 21 and the moving ring 22 has high precision characteristics, allowing for accurate control of the material block's advance distance. This ensures consistent material position before each shearing, improving shearing dimensional accuracy. The progressive advance distance matches the shearing rhythm, enabling automated step-by-step feeding, reducing manual intervention, and improving production efficiency.

[0035] The left end of the mounting bracket 19 on the left side is provided with a drive motor 24. The output end of the drive motor 24 is fixedly connected to a bevel gear, and the left end of the lead screw 21 is fixedly connected to a bevel gear disk that can mesh with the bevel gear.

[0036] like Figure 7 As shown, a drive motor 24 is set as the power source. It drives the bevel gear and the conical gear disk to rotate and transmit power to the lead screw 21. Through the meshing transmission of the motor-driven gear, the lead screw 21 has high rotational accuracy. The displacement of the moving ring 22 and the material step distance are controllable, ensuring the consistency of the shearing position and improving the product dimensional accuracy.

[0037] The right end of the lead screw 21 is fixedly connected to a spur gear 25, and the right end of the mounting bracket 19 on the right side is rotatably connected to a spur gear 26. The right end of the spur gear 26 is provided with a track groove 27, and the upper side of the track groove 27 is provided with a one-way groove 28.

[0038] like Figure 8As shown, the setting straight gear 25 and spur gear 26 can pass the rotation of the lead screw to the track groove 27, drive the guide frame 29 to lift and move the front and rear pressing frame 32 to the middle, so as to clamp the material block, the track groove 27 is divided into three parts, the first part is the peripheral circular groove, the second part is the downward groove, the end of the downward groove is closer to the center of the spur gear 26, the third part is the upward groove, the lower side of the upward groove is communicated with the downward groove, the other end is communicated with the peripheral circular groove, so that when the bolt 30 is located in the peripheral circular groove, the guide frame 29 is located at the upper limit position and keeps still, when the bolt 30 enters the downward groove, the guide frame 29 descends, and the pressing frame 32 moves to the material block, when the bolt 30 completely moves to the junction of the downward groove and the upward groove, the lead screw 21 stops, and the pressing frame 32 completely presses the material block, and then the shearing can be carried out, when the bolt 30 enters the upward groove, the guide frame 29 rises, and when it enters the peripheral circular groove again, the lead screw 21 rotates to continue to advance the material block by the push rod 23, the setting one-way groove 28 can prevent the bolt 30 from entering the upward groove when the lead screw 21 rotates and the bolt 30 reaches the junction of the upward groove in the peripheral circular groove, and directly enters the other side of the peripheral circular groove through the one-way groove 28, in order to ensure that the bolt 30 can enter the one-way groove 28, a return spring can be arranged between the guide frame 29 and the heat preservation shell 3, which can always give the guide frame 29 an upward force.

[0039] The pressing assembly comprises a U-shaped guide frame 29, the guide frame 29 is slidably connected with the heat preservation shell 3, the guide frame 29 is slidably connected with a bolt 30 in the middle through a compression spring, the bolt 30 is located in the track groove 27, the bolt 30 can enter the one-way groove 28, the guide frame 29 is provided with an inclined groove 31 on each side, the two inclined grooves 31 are in a figure-eight shape, the heat preservation shell 3 is provided with two front and rear symmetrical pressing frames 32 on the right side, the pressing frame 32 is slidably connected with the positioning frame 17 on the corresponding side, the pressing frame 32 is rotatably connected with a contact wheel 33 on each side, the contact wheel 33 can contact the material block on the connection plate 8, and the pressing frame 32 is fixedly connected with a sliding pin 34 in the corresponding inclined groove 31 on the right end.

[0040] As Figure 7As shown, the guide frame 29 is configured to lift and lower via a sliding connection, which in turn drives the clamping frame 32 to clamp and release. A compression spring provides elastic pressure to the pin 30, ensuring that the pin 30 is always in contact with the track groove 27. The movement path of the pin 30 within the track groove 27 determines the movement state of the guide frame 29. An inclined groove 31 is configured, and the sliding of the sliding pin 34 within the inclined groove 31 converts the vertical movement of the guide frame 29 into the horizontal movement of the clamping frame 32, achieving clamping and releasing. The track groove 27 is driven to rotate via spur gears 25 and spur gears 26. The movement path of the pin 30 within the track groove 27 controls the lifting and lowering of the guide frame 29. That is, when the guide frame 29 descends, the inclined groove 31 pushes the sliding pin 34 inward, and the clamping frame 32 clamps the material; when the guide frame 29 rises, the clamping frame 32 releases. The clamping component and the advancing component are linked, requiring no additional power source. The rotation of the lead screw 21 simultaneously controls the material advancing and clamping actions, simplifying the structure and improving efficiency.

[0041] The material distribution assembly includes two symmetrical rotating rods 35 that can rotate synchronously. The rotating rods 35 are rotatably connected to the mounting frame 19. Swing rods 36 are fixedly connected to the left and right sides of the rotating rods 35 respectively. The two swing rods 36 on the same rotating rod 35 are perpendicular to each other. Multiple material distribution plates 37 corresponding to the swing rods 36 are slidably connected to the mounting plate 9. The material distribution plate 37 is provided with a drive groove 38. A drive pin that can be inserted into the corresponding drive groove 38 is fixedly connected to the swing rod 36.

[0042] like Figures 4 to 5 As shown, each rotating rod 35 is equipped with fixed swing rods 36 on both the left and right sides, and the two swing rods 36 on the same rotating rod 35 are perpendicular to each other, forming a 90° phase difference, so that the material distribution plates 37 move alternately. When one material distribution plate 37 rises to intercept the material, the other material distribution plate 37 falls to release the material, realizing the interval conveying of the material without manual intervention. The material distribution component works in conjunction with the conveying roller 4 to realize the automatic step-by-step conveying of the material and improve production efficiency.

[0043] A lifting frame 39 is slidably connected to the mounting plate 9. Two symmetrical connecting grooves 40 are opened on the front and rear sides of the lifting frame 39. L-shaped connecting pins are fixedly connected to the left and right sides of the outer wall of the rotating rod 35, and the connecting pins are located in the connecting grooves 40 on their corresponding sides.

[0044] like Figures 4 to 5 As shown, two symmetrical connecting slots 40 are provided on each of the front and rear sides for engaging with connecting pins to convert the up-and-down movement of the lifting frame 39 into the rotational movement of the rotating rod 35. This structure achieves precise lifting of the lifting frame 39 through mechanical linkage, ensuring that the material distribution plate 37 intercepts or releases materials as needed, improving material distribution efficiency and shearing accuracy. Its symmetrical design and compact layout enhance stability and durability, making it suitable for automated production lines, reducing manual intervention, and improving overall production efficiency.

[0045] Lifting slots 41 are respectively opened on the left and right sides of the lifting frame 39. A hydraulic rod 42 is fixedly connected to the mounting plate 9. A lifting pin is fixedly connected to the output end of the hydraulic rod 42. The left and right sides of the lifting pin are respectively located in the lifting slots 41 on their corresponding sides.

[0046] like Figures 4 to 5 As shown, a hydraulic rod 42 is set as the power device for the lifting frame 39. The hydraulic rod 42 provides a stable and adjustable driving force to ensure the reliability of the lifting action. By sliding the lifting pin in the lifting groove 41, the linear motion of the hydraulic rod 42 is converted into the lifting motion of the lifting frame 39. Through the ingenious design of hydraulic drive and lifting groove 41, this structure realizes the stable and precise lifting of the lifting frame 39, ensuring the efficiency and reliability of the material distribution process. The application of the hydraulic system not only improves the power performance, but also enhances the adaptability and automation of the equipment.

[0047] When in use, the conveyor roller 4 is started, and all conveyor rollers 4 are driven to rotate synchronously through the transmission wheel 11 and the transmission chain 12 to ensure that the material block is smoothly conveyed to the right. The rotating wheel 13 below the conveyor roller 4 is linked by the transmission belt 14. Its bevel gear meshes with the helical gear of the double-acting screw 5 to transmit part of the power to the double-acting screw 5. The double-acting screw 5 rotates and drives the cleaning plate 7 to move back and forth along the slide rod 6. The cleaning plate 7 contacts the lower side wall of the conveyor shell 2 to scrape off the fallen waste debris and avoid accumulation of pollution or jamming. The heating plate 15 conducts heat through the heating rod 16 inserted in the conveyor roller 4 to maintain a suitable temperature for the material block and ensure that the hardness decreases evenly. Hydraulic rod 42 pushes lifting pin, which drives lifting frame 39 to move up and down through lifting groove 41. The connecting groove 40 of lifting frame 39 cooperates with the connecting pin on rotating rod 35, causing rotating rod 35 to rotate. Swing rod 36 swings accordingly, driving pin to slide in driving groove 38 of material distribution plate 37, controlling material distribution plate 37 to rise and fall alternately. The left material distribution plate 37 rises to block subsequent materials, and the right material distribution plate 37 falls to release the current material. Material blocks pass through one by one at fixed intervals, realizing automatic center positioning before shearing. When material blocks pass through the tilting plate 10, they are tilted by its inclined surface, which facilitates subsequent advancement and shearing. When the material block moves to the abutment plate 8, the driving motor 24 drives the lead screw 21 to rotate through the bevel gear and the cone gear, the lead screw 21 first drives the moving ring 22 to rotate, when the push rod 23 is in the vertical state, the push rod 23 is in contact with the side wall of the limiting groove 20, then the push rod 23 pushes the material block to gradually advance to the shearing station, the spur gear 25 at the right end of the lead screw 21 drives the spur gear 26 to rotate, the track groove 27 controls the movement of the pin 30, when the pin 30 is located in the peripheral circular groove, the push rod 23 pushes the material block to advance, when the pin 30 descends along the downward moving groove, the guide frame 29 pushes the clamping frame 32 to the center through the inclined groove 31 to clamp the material, when the pin 30 reaches the end point of the downward moving groove, the lead screw 21 stops rotating, the material is completely fixed, shearing is carried out, after the shearing is completed, the lead screw 21 continues to rotate, the pin 30 returns through the upward moving groove, the clamping frame 32 is loosened, the lead screw 21 continues to rotate to advance the next section of material, until the thick sheet shearing is completed. After the shearing of a material block is completed, the lead screw 21 reverses, the push rod 23 rotates 90° to be in the vertical state and then gradually moves to the left, at the same time, under the action of the one-way groove 28, the pin 30 does not enter the upward moving groove, so that the clamping frame 32 is prevented from being misoperated.

[0048] In the present application, the motor and the hydraulic device are prior art, which will not be described in detail.

[0049] The specific embodiments described herein are merely illustrative of the spirit of the present application, and those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or use similar ways instead, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.
