Description

Technical Field

[0001] This utility model relates to the field of marble processing technology, specifically to a low-temperature drying device for marble pretreatment. Background Technology

[0002] Marble is a natural stone, mainly composed of minerals such as calcium carbonate. If the raw marble has a high water content, it will reduce the stability of the marble's internal structure. During cutting, uneven stress can easily cause chipping. Low-temperature drying pretreatment is usually required during processing, as stability will be affected at high temperatures. Low-temperature drying allows the moisture to evaporate slowly and evenly, reducing internal stress changes caused by rapid moisture loss and preventing cracks. Furthermore, the low-temperature environment will not damage the mineral structure and color of the marble, effectively protecting its appearance and physical properties.

[0003] In the prior art, Chinese Patent No. CN220135965U discloses a marble block slab drying device, including a support plate and a unloading platform. The top of the support plate is fixedly connected to a drying box, and a blowing assembly is installed on the top of the drying box. A heating mechanism and a control panel are installed on the front of the drying box. Side plates are fixedly connected to the inner wall of the drying box, and a conveyor motor is installed on the front of the side plates. A chain is provided at the output end of the conveyor motor, and the conveyor motor is connected to a conveyor belt through the chain drive. A curtain is installed above the inlet and outlet on both sides of the conveyor belt. Anti-collision components are installed on the inner wall of the side plates. With the set conveyor belt, blowing assembly, heating mechanism, anti-collision components and unloading platform, the working efficiency is much higher than that of traditional closed box drying. In addition, the inner side of the side plates is provided with an auxiliary feeding roller to prevent the inner wall of the device from being damaged by the rough marble blocks during loading and unloading, and also reduces the labor intensity of the workers.

[0004] Based on the above information, it can be seen that existing drying equipment can only dry one side of marble at a time. To achieve full drying, manual turning and re-drying are required, which not only significantly reduces drying efficiency and extends the overall production cycle, but also increases labor and time costs, resulting in a significant negative impact on production efficiency. Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a low-temperature drying device for marble pretreatment, in order to solve the problem mentioned in the background art that the existing drying devices can only complete the drying operation of a single side of the marble in one go. If full drying is to be achieved, manual turning and drying are required, which not only greatly reduces the drying efficiency and extends the overall production cycle, but also increases labor and time costs, and has a significant negative impact on production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature drying device for marble pretreatment, comprising a device body, two sets of conveyor belts symmetrically arranged at the bottom of the device body, conveyor rollers provided on the inner wall of the conveyor belts, and a drive motor connected to the end of the conveyor rollers; an automatic turning mechanism for turning the marble over is provided inside the device body, the automatic turning mechanism including a turning roller rotatably installed on the inner wall of the device body, a clamping groove provided on the inner wall of the turning roller, and a roller provided on the inner wall of the clamping groove; a guide plate provided at the end of the device body; a limiting baffle provided on the outer wall of the conveyor belt; and a cleaning mechanism for cleaning dust from the marble surface is provided inside the device body.

[0007] Furthermore, the tilting roller is located between the two sets of conveyor belts, and the length of the tilting roller is the same as the distance between the inner walls on both sides of the equipment body. The tilting roller has an "I" shaped cross-section, and the width of the conveyor belt is less than the length of the tilting roller.

[0008] Furthermore, the clamping grooves are set at equal angles on the inner walls of both sides of the turning roller, and the horizontal plane of the bottom inner wall of the clamping groove is lower than the horizontal plane of the top outer wall of the conveyor belt, and the width of the clamping groove is greater than the thickness of the marble.

[0009] Furthermore, the rollers are evenly spaced on the inner walls of both sides of the clamping groove, and the outer wall of the rollers is in contact with the outer wall of the marble.

[0010] Furthermore, the end of the turning roller is provided with a rotating shaft, and a driven pulley is fixedly installed on the outer wall of the rotating shaft. The end of the conveying roller is fixedly installed with a driving pulley, and a transmission belt connected to the driven pulley is sleeved on the outer wall of the driving pulley.

[0011] Furthermore, the guide plates are symmetrically arranged on both sides of the conveyor belt, and the ends of the guide plates are designed with bevels. The distance between the two sets of guide plates is the same as the length of the turning roller. The limiting baffles are evenly distributed on the outer wall of the conveyor belt, and the outer wall of the limiting baffles is in contact with the outer wall of the marble.

[0014] Furthermore, the suction holes are symmetrically opened on both sides of the cleaning brush and are evenly distributed. One end of the suction hole is connected to the cavity, and the other end of the suction hole penetrates vertically through the bottom outer wall of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-4 This utility model provides the following technical solution: A low-temperature drying equipment for marble pretreatment includes a main body 1. Two sets of conveyor belts 2 are symmetrically arranged at the bottom of the main body 1, and conveyor rollers 3 are provided on the inner wall of the conveyor belts 2. A drive motor is connected to the end of the conveyor rollers 3. An automatic turning mechanism for turning the marble is provided inside the main body 1. The automatic turning mechanism includes a turning roller 4 rotatably installed on the inner wall of the main body 1. A clamping groove 401 is opened on the inner wall of the turning roller 4, and a roller 402 is provided on the inner wall of the clamping groove 401. A guide plate 202 is provided at the end of the main body 1. A limiting baffle 201 is provided on the outer wall of the conveyor belts 2. The turning roller 4 is located between the two sets of conveyor belts 2, and the length of the turning roller 4 is the same as the distance between the inner walls on both sides of the main body 1. The cross-section of the turning roller 4 is designed in the shape of an "I". The width of the conveyor belt 2 is less than the length of the turning roller 4. The clamping groove 401 is located between the two sets of conveyor belts 2. The inner walls on both sides of the conveyor belt 401 are set at equal angles, and the horizontal plane of the bottom inner wall of the clamping groove 401 is lower than the horizontal plane of the top outer wall of the conveyor belt 2. The width of the clamping groove 401 is greater than the thickness of the marble. The rollers 402 are set at equal intervals on both sides of the inner walls of the clamping groove 401, and the outer wall of the rollers 402 is in contact with the outer wall of the marble. The end of the turning roller 4 is provided with a rotating shaft 5, and the outer wall of the rotating shaft 5 is fixedly installed with a driven pulley 501. The end of the conveyor roller 3 is fixedly installed with a driving pulley 301, and the outer wall of the driving pulley 301 is fitted with a transmission belt 6 connected to the driven pulley 501. The guide plates 202 are symmetrically arranged on both sides of the conveyor belt 2, and the ends of the guide plates 202 are designed with an inclined surface. The distance between the two sets of guide plates 202 is the same as the length of the turning roller 4. The limiting baffles 201 are distributed at equal intervals on the outer wall of the conveyor belt 2, and the outer wall of the limiting baffles 201 is in contact with the outer wall of the marble.

[0028] First, the marble is placed at the limiting baffle 201. As the marble is conveyed towards the turning roller 4 along the conveyor belt 2, the guide plates 202 symmetrically arranged on both sides of the conveyor belt 2 come into play. The inclined design at their ends can accurately guide the marble, ensuring that the marble moves accurately towards the turning roller 4. As the conveyor belt 2 continues to operate, the marble is conveyed to the turning roller 4. Since the turning roller 4 is located between the two sets of conveyor belts 2, and the horizontal plane of the bottom inner wall of the clamping groove 401 is lower than the horizontal plane of the top outer wall of the conveyor belt 2, the marble will smoothly enter the clamping groove 401 on the inner wall of the turning roller 4. At this time, the inner walls on both sides of the clamping groove 401 are equally spaced. The roller 402 fits against the outer wall of the marble, reducing friction while ensuring stable clamping of the marble. The drive pulley 301 at the end of the conveyor roller 3 rotates under the drive of the drive motor, which drives the driven pulley 501 through the transmission belt 6, thereby causing the turning roller 4 to rotate. As the turning roller 4 rotates, the marble turns over in the clamping groove 401 until it turns over until the outer wall of the marble fits against the outer wall of the other side of the conveyor belt 2. The marble is then conveyed and dried, completing the automatic turning process. The entire process requires no manual intervention. By utilizing the linkage design between the conveyor roller 3 and the turning roller 4, the automatic turning of the marble during the conveying process is realized, greatly improving the drying efficiency.

[0029] Example 2: Please refer to Figures 4-6 Based on Embodiment 1, a cleaning mechanism is also disclosed, the specific structure of which is as follows: The device body 1 is provided with a cleaning mechanism for cleaning dust on the marble surface. The cleaning mechanism includes a vacuum cleaner 7 fixedly installed on the top of the device body 1, and a vacuum cleaner pipe 701 is provided on the outer wall of the vacuum cleaner 7. A fixing plate 8 is fixedly installed inside the device body 1, and a cleaning brush 801 is provided at the bottom of the fixing plate 8. A cavity 802 is opened inside the fixing plate 8, and a suction hole 803 is opened on the outer wall of the fixing plate 8. Two sets of fixing plates 8 are symmetrically arranged inside the device body 1, and the length of the fixing plate 8 is the same as the distance between the inner walls on both sides of the device body 1. Two sets of vacuum cleaner pipes 701 are symmetrically arranged on both sides of the vacuum cleaner 7, and the ends of the vacuum cleaner pipes 701 are connected to the cavity 802. The suction holes 803 are symmetrically opened on both sides of the cleaning brush 801, and the suction holes 803 are evenly distributed. One end of the suction hole 803 is connected to the cavity 802, and the other end of the suction hole 803 penetrates vertically through the bottom outer wall of the fixing plate 8.

[0030] During the marble conveying and drying process, the cleaning mechanism starts working simultaneously. When the marble passes under the fixed plate 8, the cleaning brush 801 set at the bottom of the fixed plate 8 first contacts the marble surface to sweep away the dust. At this time, the vacuum cleaner 7 fixedly installed on the top of the equipment body 1 starts and generates suction. The suction is transmitted through the suction pipe 701 to the cavity 802 inside the fixed plate 8, and then through the cavity 802 to the marble surface through the suction holes 803 opened at equal intervals at the bottom of the fixed plate 8. The suction holes 803 penetrate vertically through the bottom outer wall of the fixed plate 8, which can effectively remove the dust swept down by the cleaning brush 801 and the original dust on the marble surface, and transport it to the vacuum cleaner 7 through the suction pipe 701. Since there are two sets of fixed plates symmetrically arranged inside the equipment body 1, and the suction pipes 701 are symmetrically arranged on both sides of the vacuum cleaner 7, the upper and lower surfaces of the marble can be cleaned at the same time, ensuring the cleanliness of the marble surface and providing good conditions for subsequent drying treatment, avoiding dust from affecting the drying effect and subsequent processing steps.
