Technical Field
[0001] This utility model relates to the technical field of ABS granule production equipment, and in particular to a preheating device for ABS granule production. Background Technology
[0002] Preheating is a crucial processing step in ABS granule production, and proper preheating can improve the quality and efficiency of subsequent ABS granule processing and molding. Currently available ABS granule preheating equipment suffers from several problems during operation, such as poor heat dissipation leading to excessively high internal temperatures. This not only affects the lifespan of internal electrical components and mechanical parts but may also cause performance degradation of the ABS granules due to overheating, such as degradation and discoloration, thus reducing product quality.
[0003] The inventors believe that the following defects often exist: when the preheater itself is working, it is in a high-temperature state for a long time. The long-term high temperature accelerates the aging and wear of equipment components, such as the aging of motor winding insulation and the deformation of mechanical parts, resulting in a reduction in the service life of the equipment; therefore, a preheating device for ABS granule production is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the preheater itself is in a high-temperature state for a long time during operation, which accelerates the aging of equipment components. Therefore, this invention proposes a preheating device for ABS granule production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a preheating device for ABS granule production, comprising a preheating machine body, a button installed on the surface of the preheating machine body, a heat dissipation device provided on one side of the preheating machine body, the heat dissipation device comprising a fixing frame, the fixing frame being fixedly connected to one side of the preheating machine body, a filter screen being slidably connected inside the fixing frame, two fixing rods being fixedly connected to one side of the fixing frame, a limit plate being rotatably connected to the arc surface of the fixing rods, two L-shaped plates being fixedly connected to one side of the filter screen, bolts being threaded into the L-shaped plates, and a threaded groove being provided on one side of the limit plate.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a heat dissipation device, the internal temperature of the preheater body is reduced, avoiding the preheater body from being in a high-temperature state for a long time during operation. Long-term high temperature accelerates the aging and wear of equipment components, such as aging of motor winding insulation and deformation of mechanical parts, resulting in a reduction in the service life of the equipment and improving the practicality of the device.
[0007] Preferably, a torsion spring is fitted onto the arc surface of the fixing rod, and the two ends of the torsion spring are fixedly connected to the fixing rod and the limiting plate, respectively.
[0008] The above-mentioned components achieve the following effect: they automatically open the limit plate and keep it in the open position, making it convenient for staff to remove the filter screen.
[0009] Preferably, the arc surface of the bolt is fixedly connected to the blocking plate, and the size of the bolt is adapted to the size of the threaded groove of the limiting plate.
[0010] The aforementioned components achieve the following effect: preventing bolts from falling off and avoiding situations where workers turn the bolts too many times, causing the bolt's arc surface to separate from the L-shaped plate. This would prevent workers from having to perform secondary installation when they need to use bolts for fixing, thus increasing their workload.
[0011] Preferably, the surface of the fixing frame is fixedly connected to two positioning plates, and the positioning plates are fixedly connected to the surface of the preheater body.
[0012] The effects achieved by the above components are: to calibrate the position of the filter screen, simplify the filter screen installation process, reduce complex operation steps such as repeated manual adjustment and alignment, enable staff to complete the filter screen installation more quickly and conveniently, effectively improve installation efficiency, and reduce the difficulty and time cost of manual installation.
[0013] Preferably, the surface of the preheater body is provided with a protective device, the protective device including a fixed plate, the fixed plate being fixedly connected to the surface of the preheater body, two protective plates being slidably connected inside the fixed plate, a connecting rod being fixedly connected to one side of the fixed plate, a single-hole plate being fixedly connected to one end of the connecting rod, and an insert rod being slidably inserted inside the single-hole plate.
[0014] The aforementioned components achieve the following effect: by incorporating protective devices, the buttons are protected, preventing accidental touches by operators that could lead to sudden starts or stops of the preheating machine, or changes to critical parameters such as temperature and time. Accidental touches could cause uneven heating and temperature control issues in the preheating ABS granules, resulting in a decrease in granule quality, thus improving the reliability of the device.
[0015] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the insertion rod and the single-hole plate, respectively.
[0016] The above-mentioned components achieve the following effects: they improve the stability of the insertion rod, keep the insertion rod in a fixed position, prevent the protective plate from loosening or shifting, effectively ensure the stable and reliable protection function of the button, and provide long-term protection for safe operation during preheating.
[0017] Preferably, the arc surface of the connecting rod is rotatably connected to an arc plate, and the arc plate is slidably connected to the fixed plate.
[0018] The aforementioned components achieve the following effect: they restrict the position of the insertion rod, preventing the insertion rod from being affected by external forces when the protective plate is moved, thus avoiding the insertion rod sliding within the fixed plate and causing friction between the insertion rod and the protective plate, which could lead to damage to the insertion rod.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting up a heat dissipation device, the temperature inside the preheater body is reduced, avoiding the preheater body from being in a high-temperature state for a long time during operation. Long-term high temperature accelerates the aging and wear of equipment components, such as aging of motor winding insulation and deformation of mechanical parts, resulting in a reduction in the service life of the equipment, thus improving the practicality of the device.
[0021] 2. In this utility model, by setting a protective device, the button is protected, preventing workers from accidentally touching it during operation. This could lead to the preheating machine suddenly starting or stopping, or changing critical parameters such as temperature and time. Accidental touch could cause uneven heating and temperature control issues in the preheating ABS granules, resulting in a decrease in granule quality, thus improving the reliability of the device.

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a preheating device for ABS granule production, including a preheating machine body 1. A button 2 is installed on the surface of the preheating machine body 1, and a heat dissipation device 3 is provided on one side of the preheating machine body 1. By setting the heat dissipation device 3, the temperature inside the preheating machine body 1 is reduced, avoiding the preheating machine body 1 from being in a high-temperature state for a long time during operation. Long-term high temperature accelerates the aging and wear of equipment components, such as aging of motor winding insulation and deformation of mechanical parts, resulting in a reduction in the service life of the equipment, thus improving the practicality of the device. A protective device 4 is provided on the surface of the preheating machine body 1, which protects the button 2 and prevents the operator from accidentally touching the button 2 during operation. This would prevent the preheating machine body 1 from suddenly starting or stopping, or changing key parameters such as temperature and time due to misoperation. Once an accidental touch occurs, the ABS granules being preheated may be heated unevenly, the temperature may run out of control, and the quality of the granules may decrease, thus improving the reliability of the device.
[0029] The specific setup and function of its heat dissipation device 3 and protection device 4 will be explained below.
[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the heat dissipation device 3 includes a fixing frame 31, which is fixedly connected to one side of the preheater body 1. A filter screen 32 is slidably connected inside the fixing frame 31. Two fixing rods 33 are fixedly connected to one side of the fixing frame 31. A limiting plate 36 is rotatably connected to the arc surface of the fixing rods 33. Two L-shaped plates 34 are fixedly connected to one side of the filter screen 32. Bolts 35 are threaded into the L-shaped plates 34. A threaded groove is opened on one side of the limiting plate 36. A torsion spring 39 is sleeved on the arc surface of the fixing rods 33. The two ends of the torsion spring 39 are fixedly connected to the fixing rods 33 and the limiting plate 36 respectively. When the operator needs to remove the filter screen 32, the operator first rotates the bolts 35 to rotate the L-shaped plates 34. Until the arc surface of bolt 35 separates from the threaded groove of limit plate 36, the torque of torsion spring 39 drives limit plate 36 to rotate on the arc surface of fixed rod 33 until limit plate 36 no longer affects the movement of filter screen 32. Then, the operator can pull filter screen 32 to move until the surface of filter screen 32 separates from fixed frame 31. At this time, the operator can clean the dust and stains on the surface of filter screen 32, achieving the effect of automatically opening limit plate 36, while keeping limit plate 36 in the open position, making it convenient for the operator to pull out filter screen 32. The arc surface of bolt 35 is fixedly connected to baffle plate 37. The size of bolt 35 is adapted to the size of threaded groove of limit plate 36. When the operator needs to disassemble filter screen... At time 32, the operator first rotates bolt 35 within the L-shaped plate 34. Bolt 35 moves the blocking plate 37 until its surface is in contact with the L-shaped plate 34. At this point, the arc surface of bolt 35 is completely separated from the limiting plate 36, thus preventing bolt 35 from falling off. This avoids situations where the operator rotates bolt 35 too many times, causing its arc surface to separate from the L-shaped plate 34. If the operator needs to use bolt 35 for fixing, a secondary installation would be required, increasing the operator's workload. Two positioning plates 38 are fixedly connected to the surface of the fixing frame 31. The positioning plates 38 are fixed to the surface of the preheater body 1. With a fixed connection, when the staff needs to install the filter screen 32, the staff first pushes the filter screen 32 on the surface of the preheater body 1. The filter screen 32 drives the L-shaped plate 34 to move until the surface of the filter screen 32 is in contact with the positioning plate 38. Then the staff continues to push the filter screen 32. At this time, the position of the filter screen 32 will shift to a certain extent until the surface of the filter screen 32 is in contact with the surface of the fixing frame 31. At this time, the position of the filter screen 32 is calibrated, which simplifies the installation process of the filter screen 32, reduces the complex operation steps such as repeated manual adjustment and alignment, and enables the staff to complete the installation of the filter screen 32 more quickly and conveniently, effectively improving the installation efficiency and reducing the difficulty and time cost of manual installation.
[0031] Reference Figure 4 and Figure 5As shown, specifically, the protective device 4 includes a fixed plate 41, which is fixedly connected to the surface of the preheater body 1. Two protective plates 42 are slidably connected inside the fixed plate 41. A connecting rod 43 is fixedly connected to one side of the fixed plate 41, and a single-hole plate 44 is fixedly connected to one end of the connecting rod 43. An insert rod 45 is slidably inserted into the single-hole plate 44, and a spring 46 is sleeved on the arc surface of the insert rod 45. The two ends of the spring 46 are fixedly connected to the insert rod 45 and the single-hole plate 44, respectively. When the operator needs the protective button 2, firstly... The worker pulls the insertion rod 45 and slides it within the single-hole plate 44. At this time, the spring 46 is stretched. Then, the worker pushes the protective plate 42 to slide within the fixed plate 41 until the protective plate 42 is completely in contact with the inner surface of the fixed plate 41. At this point, the worker can release the insertion rod 45. The rebound force of the spring 46 then causes the insertion rod 45 to slide within the single-hole plate 44 until it is inserted into the protective plate 42. This achieves the effect of improving the stability of the insertion rod 45, keeping its position fixed, and preventing the protective plate 42 from loosening or shifting. This effectively ensures the stable and reliable protection function of button 2, providing long-term protection for safe operation during preheating. The arc surface of the connecting rod 43 is rotatably connected to the arc plate 47, which is slidably connected to the fixed plate 41. When the operator needs to install the protective plate 42, the operator first pulls the insertion rod 45 to slide within the single-hole plate 44. At this time, the spring 46 is stretched until the insertion rod 45 no longer affects the movement of the protective plate 42 and the rotation of the arc plate 47. Then the operator can rotate the arc plate 47. After the curved plate 47 is rotated to a certain angle, the worker can release the insert rod 45 until one end of the insert rod 45 abuts against the curved plate 47. At this time, the worker can push the protective plate 42 to slide within the fixed plate 41. This achieves the effect of restricting the position of the insert rod 45, preventing the insert rod 45 from being affected by external forces when the worker moves the protective plate 42, thus preventing the insert rod 45 from sliding within the fixed plate 41 and causing a certain degree of friction between the insert rod 45 and the protective plate 42, which could lead to damage to the insert rod 45.
[0032] Working principle: When the operator needs to disassemble the filter screen 32, firstly, the operator rotates the bolt 35 within the L-shaped plate 34. The bolt 35 moves the baffle plate 37 until its surface is in contact with the L-shaped plate 34. At this point, the arc surface of the bolt 35 is completely separated from the limiting plate 36. The torque of the torsion spring 39 causes the limiting plate 36 to rotate on the arc surface of the fixing rod 33 until the limiting plate 36 no longer affects the movement of the filter screen 32. Then, the operator can pull the filter screen 32 until its surface separates from the fixing frame 31. At this point, the operator can clean the dust and dirt from the surface of the filter screen 32. When the operator needs to install the filter screen 32... First, the operator pushes the filter screen 32 onto the surface of the preheater body 1. The filter screen 32 moves the L-shaped plate 34 until the surface of the filter screen 32 is in contact with the positioning plate 38. Then, the operator continues to push the filter screen 32, at which point the position of the filter screen 32 shifts to a certain extent until the surface of the filter screen 32 is in contact with the surface of the fixing frame 31. This achieves the effect of reducing the temperature inside the preheater body 1, preventing the preheater body 1 from being in a high-temperature state for a long time during operation. Long-term high temperature accelerates the aging and wear of equipment components, such as aging of motor winding insulation and deformation of mechanical parts, resulting in a reduction in the service life of the equipment and improving the practicality of the device.
[0033] When the worker needs to install the protective button 2, firstly, the worker pulls the insert rod 45 and slides it within the single-hole plate 44. At this time, the spring 46 is stretched. Then, the worker pushes the protective plate 42 to slide within the fixed plate 41 until the protective plate 42 is completely flush with the inner surface of the fixed plate 41. At this point, the worker can release the insert rod 45. The rebound force of the spring 46 then causes the insert rod 45 to slide within the single-hole plate 44 until the insert rod 45 is inserted into the protective plate 42. When the worker needs to install the protective plate 42, firstly, the worker pulls the insert rod 45 and slides it within the single-hole plate 44. At this time, the spring 46 is stretched until the insert rod 45 no longer affects the movement of the protective plate 42, and the insert rod 45 does not... The rotation of the arc plate 47 is affected, and the operator can then rotate the arc plate 47. When the arc plate 47 rotates to a certain angle, the operator can release the insert rod 45 until one end of the insert rod 45 abuts against the arc plate 47. At this time, the operator can push the protective plate 42 to slide within the fixed plate 41, achieving the effect of protecting the button 2. This prevents the operator from accidentally touching the button 2 during work, which could cause the preheating machine body 1 to suddenly start or stop, or change key parameters such as temperature and time due to misoperation. Once a misoperation occurs, the ABS granules being preheated may be heated unevenly, the temperature may run out of control, and the quality of the granules may decrease, thus improving the reliability of the device.
