Description

Technical Field

[0001] This application belongs to the field of waterproof membrane production technology, specifically relating to waterproof membrane substrate buffer equipment. Background Technology

[0002] The substrate is the basic framework of a reinforced waterproof membrane. In the production of this type of waterproof membrane, the substrate is supplied in roll form. When one roll of substrate is used up, another needs to be replaced, which can cause production line interruptions and affect production efficiency. Therefore, existing waterproof membrane production lines often have a substrate buffer device, which essentially creates a transition zone between the unwinding and processing steps. Even if the unwinding step is interrupted due to the need to replace the substrate roll, the required substrate can still be supplied to the processing step by consuming the substrate stored in the buffer device, allowing the processing step to continue. When replacing a substrate roll, it is generally necessary to manually overlap the beginning of the next substrate roll with the end of the previous one. The end of the previous substrate roll is located at the feed point of the buffer device. If the end of the previous substrate roll cannot be kept stationary while consuming the buffered substrate, it will cause difficulties in overlapping and affect the overlap effect. Utility Model Content

[0003] The purpose of this application is to provide a waterproof membrane substrate buffer device that can adjust the substrate buffer amount in real time, ensuring that the end of the substrate remains relatively stationary while maintaining the substrate supply, so as to facilitate the overlap and replacement of another substrate, ensuring the overlap effect, enabling the production line to operate continuously, while reducing the footprint of the buffer device and shortening the production line length.

[0034] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0035] A waterproofing membrane carcass buffer device and a waterproofing membrane production line according to the present application are described below with reference to the accompanying drawings.

[0036] As shown in Figures 1 to 3 The first exemplary embodiment of the present application provides a waterproofing membrane carcass buffer device, which includes a rack 1, a conveying mechanism and a drying mechanism 4. The rack 1 is arranged vertically and has a carcass buffer area 101 formed inside. The conveying mechanism is arranged in the carcass buffer area 101 and includes an upper roller set and a lower roller set arranged vertically and spaced apart. The upper roller set includes a plurality of upper rollers 2 arranged in sequence and spaced apart horizontally. The lower roller set includes a plurality of lower rollers 3 arranged in sequence and spaced apart horizontally. The drying mechanism 4 is used to dry the waterproofing membrane carcass in the carcass buffer area 101.

[0037] Specifically, the plurality of upper rollers 2 and the plurality of lower rollers 3 are arranged alternately in sequence and vertically along the conveying direction of the waterproofing membrane carcass, so that the waterproofing membrane carcass can pass through each upper roller and lower roller alternately in sequence. By adjusting the vertical spacing of the upper roller set and the lower roller set, the buffer amount of the waterproofing membrane carcass can be adjusted. Since the rack 1 is arranged vertically, the carcass buffer area 101 is also arranged vertically adaptively. Therefore, the waterproofing membrane carcass buffer device of the present exemplary embodiment can reduce the floor area, shorten the length of the waterproofing membrane production line and save the site cost while achieving a large carcass buffer amount.

[0038] When it is necessary to consume the waterproof roll body cached in the body cache area to maintain the supply of the waterproof roll body output to the outside, the vertical distance between the upper roller set and the lower roller set can be gradually reduced, i.e., the height of the upper roller set is lowered, or the height of the lower roller set is raised, or both the upper roller set is lowered and the lower roller set is raised, so that the waterproof roll body cached is output to the downstream processing equipment, and during the output of the waterproof roll body, the output of the waterproof roll body can maintain a certain appropriate tension, avoiding the case that the waterproof roll body enters the subsequent processing process in a relaxed or too tight state.

[0039] The waterproof roll body is usually stored in the form of a roll, and when supplied, it is first input to the waterproof roll body caching device and then output to the downstream processing equipment from the waterproof roll body caching device. Under the driving of the downstream processing equipment or other driving mechanism, the waterproof roll body in the roll can be continuously unwound. After the roll of waterproof roll body is consumed, a new roll needs to be replaced in time, specifically, the first end of the new waterproof roll body needs to be spliced to the end of the old waterproof roll body, so as to ensure the continuous supply of the waterproof roll body.

[0040] Therefore, when replacing the new waterproof roll body, the old waterproof roll body can be output from the body cache area to the downstream processing equipment under the driving of the downstream processing equipment or other driving mechanism. During this period, thanks to the adaptive gradual reduction of the vertical distance between the upper roller set and the lower roller set, the end of the old waterproof roll body can be kept stationary to facilitate splicing with the first end of the new waterproof roll body, so as to ensure that the two waterproof roll bodies have good splicing quality and prevent misalignment and insecure splicing.

[0041] In addition, the waterproof roll body caching device of the present exemplary embodiment integrates the air-drying mechanism, performs dehydration and drying treatment on the waterproof roll body in the body cache area through the air-drying mechanism, and ingeniously utilizes the feature that the waterproof roll body stays in the waterproof roll body caching device for a relatively long time, so that the waterproof roll body in the body cache area can be fully dried, thereby achieving the purpose of reducing the energy consumption of the drying process, reducing the floor area of the air-drying mechanism, further shortening the length of the waterproof roll production line, and reducing the site cost.

[0042] In an embodiment, the upper roller set can be adjusted in vertical lifting, so as to adjust the distance with the lower roller set, and play the effect of increasing or reducing the caching amount of the waterproof roll body. Specifically, as shown in FIG. 1, the upper roller set is connected to the lifting mechanism 2 through the connecting rod 3, and the lifting mechanism 2 is connected to the lifting motor 4. Figure 1As shown, the conveying mechanism further comprises a movable support 5, and the upper roller set is arranged on the movable support 5, wherein the end of the upper roller 2 is pivotally connected to the movable support 5, and the waterproof coiled material carcass buffering device further comprises a lifting driving mechanism for driving the movable support 5 to move up and down, so that the upper roller set can be adjusted to move up and down in the vertical direction. In the embodiment, the movable support 5 is a frame structure, and a plurality of upper rollers 2 are arranged in the movable support 5 in sequence, and the movable support 5 and the upper rollers 2 are pivotally connected through bearing supports.

[0043] Further, the inside of the rack 1 is further formed with a counterweight moving area 102, the counterweight moving area 102 is arranged adjacent to the carcass buffering area 101, the lifting driving mechanism comprises a counterweight block assembly 6 arranged in the counterweight moving area 102 and adjustable in the vertical position, a first transmission shaft 7 arranged above the counterweight moving area 102, and a second transmission shaft 8 arranged above the carcass buffering area 101, the first transmission shaft 7 is pivotally connected to the rack 1 and is provided with a first transmission gear 701, the second transmission shaft 8 is pivotally connected to the rack 1 and is provided with a second transmission gear 801, the first transmission gear 701 and the second transmission gear 801 are in meshing transmission connection through a hoisting chain 9, and the two ends of the hoisting chain 9 are fixedly connected to the movable support 5 and the counterweight block assembly 6 respectively. In other words, the first transmission gear 701 and the second transmission gear 801 both have the effect of a fixed pulley. Preferably, the weight of the counterweight block assembly 6 is at least greater than the total weight of the movable support 5, the upper roller set, and the waterproof coiled material carcass wound on the upper roller set.

[0044] Therefore, by adjusting the height of the counterweight block assembly 6 in the counterweight moving area 102, the movable support 5 can be moved vertically. For example, when the counterweight block assembly 6 is raised, the movable support 5 is lowered under the action of gravity, so that the upper roller set and the waterproof coiled material carcass wound on the upper roller set are lowered; when the counterweight block assembly 6 is lowered, the movable support 5 can be raised under the drive of the counterweight block assembly 6, so that the upper roller set and the waterproof coiled material carcass wound on the upper roller set are raised. In the counterweight moving area 102, the counterweight block assembly 6 can be fixed at any height position on the rack 1, for example, by being connected to the rack 1 through a pin shaft, or by being pulled up or down by a lifting device, and the application does not limit the way of driving the counterweight block assembly 6 to move up and down.

[0045] In an embodiment, the lifting driving mechanism further comprises a rotating driving device 10 for driving the first transmission shaft 7 and / or the second transmission shaft 8 to rotate, by driving the first transmission shaft 7 and / or the second transmission shaft 8 to rotate, so that the first transmission gear 701 and / or the second transmission gear 801 rotates, thereby causing the counterweight block assembly 6 and the movable support 5 located at the two ends of the hoisting chain 9 to move up and down respectively and adjust the relative position.

[0046] Further, the first transmission shaft 7 and / or the second transmission shaft 8 is provided with a driven gear 11, the rotating driving device 10 comprises a driving shaft provided with a driving gear 1001, the driving gear 1001 and the driven gear 11 are in meshing transmission connection through a transmission chain 12. Thus, the rotating driving device 10 outputs power through the driving gear 1001 to drive the driven gear 11 to rotate, i.e. to drive the first transmission shaft 7 and / or the second transmission shaft 8 to rotate, so as to drive the counterweight assembly 6 and the movable support 5 at both ends of the hoisting chain 9 to move up and down relative to each other. Preferably, a rotary motor with self-locking function is used as the rotating driving device 10, when the movable support 5 moves to a proper height, the rotating driving device 10 is self-locked, so that the first transmission shaft 7 and / or the second transmission shaft 8 will not rotate, thereby stabilizing the movable support 5 and the counterweight assembly 6 at the corresponding height positions, respectively.

[0047] In an embodiment, the first transmission shaft 7 is provided with at least two first transmission shafts 7, the at least two first transmission shafts 7 are arranged in sequence and spaced apart in the transverse direction, each first transmission shaft 7 is provided with at least two first transmission gears 701 arranged in sequence and spaced apart in the axial direction, each first transmission gear 701 on any two first transmission shafts 7 is arranged in staggered position, the second transmission shaft 8 is provided with at least four second transmission gears 801 arranged in sequence and spaced apart in the axial direction, each second transmission gear 801 is arranged in position opposite to each first transmission gear 701. For example, in the embodiment shown in the drawings, the movable support 5 is a rectangular frame, adaptively, the first transmission shaft 7 is provided with two first transmission shafts 7 distributed on the two sides in the transverse direction of the movable support 5, each first transmission shaft 7 is provided with two first transmission gears 701 distributed on both ends of the first transmission shaft 7, the second transmission shaft 8 is provided with four second transmission gears 801, and the four second transmission gears 801 are in meshing transmission connection with the four first transmission shafts 7 through the four hoisting chains 9. Under the pulling of the four hoisting chains 9, the movable support 5 can stably adjust the up roller group and the waterproof coiled body wound on the up roller group in the coiled body buffer area 101. Figure 1

[0048] In Figure 1 ​In the shown embodiment, the air-drying mechanism 4 is arranged at one side of the bottom of the frame 1 and is used for air-drying the waterproof roll body wound on the lower roller group. Specifically, the air-drying mechanism 4 comprises a fan 401 and a plurality of air knives 402 connected with the fan 401 in a pipeline manner, the plurality of air knives 402 are arranged one by one below the plurality of lower roller cylinders 3 respectively, and the top of each air knife 402 is formed as a blade-shaped air outlet portion extending along the axial direction of the lower roller cylinder 3. Thus, when the air-drying dehydration treatment of the waterproof roll body is required, the fan 401 is started to input high-pressure air into each air knife 402 respectively, and the air is sprayed from the blade-shaped air outlet portion of each air knife 402 to the waterproof roll body wound on the lower roller group respectively. During the process, the blade-shaped air outlet portion can further compress the air, so as to increase the air outlet speed and improve the air-drying efficiency of the waterproof roll body. In addition, in the embodiment, the air knives 402 are arranged below the lower roller cylinders 3, so as to avoid interfering with the conveying movement and lifting adjustment of the waterproof roll body in the roll body buffer area 101, while saving the floor area of the air-drying mechanism 4 and reducing the site cost.

[0049] In one embodiment, the fan 401 is an electric hot air fan capable of preparing high-temperature and high-pressure hot air. Since the density of hot air is small, the flow direction of the hot air is from bottom to top. Therefore, by arranging the air knives 402 below the lower roller cylinders 3, the hot air can flow from bottom to top to the entire roll body buffer area 101, further improving the air-drying dehydration efficiency of the waterproof roll body.

[0050] In one embodiment, the conveying mechanism comprises a tension sensor (not shown in the figure) for detecting the tension of the waterproof roll body wound between the upper roller group and the lower roller group. When the waterproof roll body is buffered in the roll body buffer area 101, the tension of the waterproof roll body can be adjusted by adjusting the vertical distance between the upper roller group and the lower roller group. In the case where the tension of the waterproof roll body is required to be kept within a certain range, the tension sensor of the embodiment can be used to detect the tension of the waterproof roll body in real time, so that the operator can adjust the vertical distance between the upper roller group and the lower roller group according to the detection result of the tension sensor. In the case where the tension of the waterproof roll body is required to be kept within a certain range, the tension sensor of the embodiment can be used to detect the tension of the waterproof roll body in real time, so that the operator can adjust the vertical distance between the upper roller group and the lower roller group according to the detection result of the tension sensor. Figure 1 In the shown embodiment, the rotation driving device 10 and the tension sensor can work cooperatively. Specifically, the rotation driving device 10 can drive the upper roller group to ascend or descend according to the detection result of the tension sensor, so as to ensure that the tension of the waterproof roll body is kept within a certain range and realize the automatic operation of tension adjustment.
