Description
A construction waste recycling and reprocessing device Technical Field
[0001] This invention relates to the field of construction waste recycling technology, and in particular to a construction waste recycling and reuse device. Background Technology
[0002] Construction formwork is a temporary support structure. After construction is completed, the waste formwork needs to be recycled and cut into strips as needed. After processing, strips of different lengths are spliced together, and then composite timber is made through processes such as planing and gluing. Chinese patent application number CN201910341554.0 describes a composite timber and its production line. This invention allows the timber strips in multiple length directions to be distributed in an interlaced manner when overlapping, thereby achieving the purpose of unlimited timber length. At the same time, glue is used to bond the surface of the timber strips to the glass fiber cloth covering them, improving the strength of the composite timber. However, this invention first plans the timber strips and then applies glue. When the spliced timber strips are planed, they are very easy to deviate along the planing direction, resulting in insufficient contact between the front and rear ends of the timber strips, or even separation from each other, which seriously affects the strength of the subsequently produced composite timber and reduces product quality.
[0003] Meanwhile, the ends of the wood strips are irregular, and the existing planing equipment cannot flatten the ends of the wood strips. This results in a small contact area between the ends of the wood strips when they are spliced with adjacent wood strips. The existing equipment relies on glue to fill the gaps, which reduces the strength of the composite wood and makes it prone to breakage or delamination during use, affecting its supporting effect in construction.

Detailed Implementation
[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Example 1
[0037] As shown in Figures 3-7, a construction waste recycling and reprocessing device includes a first fixed frame 1, a fixed seat 2, and a conveyor belt 3; the fixed seat 2 is installed on the first fixed frame 1; the conveyor belt 3 is provided on the fixed seat 2 and is located behind the fixed seat 2; wooden boards 8 are conveyed on the conveyor belt 3.
[0038] It also includes limit blocks 4, fixing frames 5, glue spray pipes 6, guide plates 7, and a cutting system; four limit blocks 4 are installed on the fixing base 2, and the appropriate number of limit blocks 4 is set according to the specific situation; the four limit blocks 4 are connected by springs and rubber strips, and there is a gap between the upper sides of each limit block 4, so that multiple wooden boards 8 can form a movable space through the limit blocks 4, avoiding the rigid connection between the wooden boards 8, which would cause two wooden boards 8 to separate after splicing, affecting subsequent work; two left-right symmetrical inclined surfaces 3001 are set on the conveyor belt 3; with the view from back to front as the reference, the two inclined surfaces 3001 gradually move towards the rear in a figure-eight shape, and finally tend to be parallel; so that the four wooden boards After passing through the four limiting blocks 4, the boards 8 are guided by the inclined plane 3001 to gradually form a state where they are connected at the bottom and spread out at the top, which facilitates subsequent glue injection into the gaps between the boards 8. A fixed frame 5 is installed on the conveyor belt 3. A feed port 5001 is set on the front side of the fixed frame 5. A glue spraying pipe 6 is set in the middle of the fixed frame 5. The glue spraying pipe 6 is equipped with three horizontally arranged glue spraying nozzles 6001, and each glue spraying nozzle 6001 is located above the gap between two boards 8. The existing technology first merges the boards 8 together and then injects glue, so that the surface of the merged boards 8 is evenly coated with glue. Compared with the traditional glue injection mode, the glue is injected into the gaps between the boards 8 through the glue spraying nozzles 6001. To increase the adhesion strength between the wooden boards 8, thereby enhancing the strength and quality of the finished product; guide plates 7 are installed inside the fixed frame 5; the lower surface of each guide plate 7 is set to a horizontal state, so that the lower sides of the four wooden boards 8 always remain in contact; the upper side of each guide plate 7 is set to a state that is inclined away from the wooden boards 8, and the upper side of the guide plate 7 gradually returns to a state perpendicular to the conveyor belt 3 from front to back, so that the upper sides of the four wooden boards 8 gradually merge after being guided by the upper side of the guide plate 7; a discharge port 5002 is provided on the rear side of the fixed frame 5, and the opening area of the inlet 5001 is larger than the opening area of the discharge port 5002, so that the upper sides of the four wooden boards 8 are kept in contact by the inclined surface 3001 on the conveyor belt 3. At certain intervals, the glue is sprayed through the glue nozzles 6001 on the glue spray pipe 6, and then guided by the guide plate 7 to gradually merge the four wooden boards 8. Finally, after passing through the discharge port 5002, the four wooden boards 8 that have been glued and merged are side-planed. Since the composite wood is made by distributing and splicing templates of different lengths in an interlaced manner, compared with the traditional method of side-planing and then glue injection, this device first injects glue into the wooden boards 8 to make them stable before side-planing, thereby effectively preventing the spliced wooden boards 8 from shifting during the side-planing process, thus avoiding low strength of the finished composite wood and affecting product quality; a cutting system is installed on the fixed base 2.
[0039] Each limiting block 4 has a guide block 4001 on its front side; the guide block 4001 allows the wooden board 8 to enter the limiting block 4 more smoothly and guides it into an inclined state, which facilitates subsequent work.
[0040] It also includes a first scraper 101, a first receiving tube 102, and a collection tube 103; each guide plate 7 has several guide grooves 7001; each guide plate 7 has several first scrapers 101 fixedly connected to it, and each first scraper 101 is located behind the adjacent guide groove 7001; each guide plate 7 has a first receiving tube 102 fixedly connected to its lower side; each first receiving tube 102 has a feeding groove 10201, and each feeding groove 10201 is located below the adjacent guide groove 7001; each first receiving tube 102 has a collection tube 103 connected to the side away from the guide plate 7; the four wooden boards 8 are guided by the guide plates 7. As the boards gradually merge, the glue between the four boards 8 overflows outwards due to the merging of the boards 8. At this time, the first scraper 101 scrapes off one side of the adjacent boards 8 being transported backwards. After being scraped off by the first scraper 101, the glue flows down into the feed trough 10201 along the guide groove 7001, then enters the first collection pipe 102, and finally is discharged to the outside through the collection pipe 103 for recycling. The first scraper 101 removes the residual glue on the boards 8 to prevent glue from overflowing and dripping onto the conveyor belt 3 after the boards 8 merge, thus affecting the operation of the conveyor belt 3. At the same time, the collected glue is discharged to the outside through the collection pipe 103 for recycling, thereby reducing resource waste.
[0041] Example 2

At this time, the external identification device identifies the wooden board 8. When the external identification device identifies irregular parts at both ends of the wooden board 8, it controls the electric saw blade 205 to cut it and pushes the cut wooden board 8 to the adjacent wooden board 8 on the back side so that its two ends always keep in contact. The electric saw blade 205 cuts off the irregular parts on the wooden board 8, making the two adjacent wooden boards 8 fit more tightly, thereby preventing the presence of irregular parts from affecting the strength of the finished product and further avoiding affecting the product quality.
[0043] The cutting system also includes a slide rail 202, an electric slider 203, and a drive unit 204; the slide rail 202 is fixedly connected to the second fixed frame 201; the electric slider 203 is slidably connected to the slide rail 202; the drive unit 204 is fixedly connected to the electric slider 203, and the drive unit 204 is an electric push rod; the output end of the drive unit 204 is fixedly connected to the electric saw blade 205. The wooden board 8 is first identified and positioned by the identification device, and then the electric slider 203 is controlled to slide left and right on the slide rail 202 to reach the corresponding position. Then, the drive unit 204 is controlled to drive the electric saw blade 205 to move up and down, and finally the irregular parts at the front and rear ends of the wooden board 8 are cut.
[0044] It also includes a fan 206; a fan 206 is fixedly attached to both the left and right sides of the second fixing frame 201; when the electric saw blade 205 cuts the wooden board 8, the sawdust produced during the cutting process splashes around and even adheres to the wooden board 8. At this time, the fan 206 blows the sawdust into the collection groove 2001 when the electric saw blade 205 cuts the wooden board 8, preventing the sawdust from remaining on the wooden board 8 and avoiding the residual sawdust from reducing the bonding strength between the wooden boards 8 when applying glue.
[0045] It also includes a curved plate 207 and a first baffle 208; the curved plate 207 is fixedly connected to the fixed base 2, and the height of the curved plate 207 can be adjusted up and down; the curved plate 207 is located above the four limiting blocks 4; the first baffle 208 is fixedly connected to the curved plate 207; the first baffle 208 blocks the wood chips generated when the electric saw blade 205 cuts the wood board 8, and at the same time prevents the fan 206 from blowing the wood chips onto the wood board 8 on the rear side, further avoiding the wood chips remaining on the wood board 8 from affecting the bonding strength between the wood boards 8.
[0046] As shown in Figure 12, it also includes a scraper 209; the scraper 209 is fixedly attached to the lower rear surface of the curved plate 207, and the scraper 209 is made of rubber; the lower side of the scraper 209 contacts the upper side of the wooden board 8 passing through the limiting block 4; when the electric saw blade 205 cuts the wooden board 8, some wood chips and dust will adhere to the surface of the wooden board 8 by the blowing force of the fan 206. At this time, the scraper 209 scrapes off the dust and wood chips on the upper side of the wooden board 8, thereby reducing the dust and wood chips carried on the wooden board 8.
[0047] Example 3
[0048] Based on Embodiment 2, as shown in Figures 9-11, it further includes a glue-applying pipe 301, a second receiving pipe 303, a crankshaft 304, and a second scraper 305; the glue-applying pipe 301 is fixedly connected to the front side of the fixed frame 5, and the glue-applying pipe 301 is located above the feed inlet 5001; the glue-applying pipe 301 applies a small amount of glue to the surface of each of the four wooden boards 8, thereby wetting the surface of the four wooden boards 8, which facilitates the bonding between the four wooden boards 8 after subsequent glue application. At the same time, as the two inclined surfaces 3001 on the conveyor belt 3 gradually guide the four wooden boards 8 to bottom contact, during the process of spreading out on the upper side, some of the dust and wood chips on the upper side of the wooden boards 8, after being scraped off by the scraper 209, will remain in the gaps between the wooden boards 8 as they fall downwards. At this time, the glue-applying pipe 301 adheres to the dust and wood chips remaining between the wooden boards 8, thereby achieving dust reduction; the second receiving pipe 303 is fixedly connected to the rear of the feed inlet 5001 of the fixed frame 5; the second receiving pipe 303 is fixedly connected to the rear of the feed inlet 5001 of the fixed frame 5; the second receiving pipe 303 is fixedly connected to the rear of the feed inlet 5001 of the fixed frame 5; the second receiving pipe 301 is fixedly connected to the rear of the feed inlet 5001 of the fixed frame 5; the second receiving pipe 301 is fixedly connected to the rear of the feed inlet 5001, and the second receiving pipe 305 is fixedly connected to the rear of the feed inlet 5001; the second receiving pipe 301 is fixedly connected to the rear of the feed inlet 5001, and the A crankshaft 304 is rotatably connected inside the two receiving tubes 303. Two second scrapers 305 are fixed to the left and right sides of each connecting rod journal on the crankshaft 304, and each second scraper 305 is bent away from the connecting rod journal. Taking a right-to-left view as a reference, the second scrapers 305 rotate by rotating the crankshaft 304 clockwise. During the rotation of the crankshaft 304, when the connecting rod journal on the crankshaft 304 offsets and lifts the upper wooden boards 8 one by one, the second scrapers 305 on the left and right sides of the connecting rod journal enter the gaps between the upper wooden board 8 and the adjacent wooden boards 8. Then, during the rotation, the sawdust and dust adhering to the glue in the gaps are scraped off and fall into the second receiving tube 303, and finally discharged to the outside. This prevents the sawdust and dust remaining in the gaps from affecting the bonding effect of the four wooden boards 8 when the four wooden boards 8 are glued and joined together, and further avoids affecting the strength and quality of the finished product.
[0049] It also includes a servo motor 302; the servo motor 302 is fixedly connected to the right side of the fixed frame 5, and the output shaft of the servo motor 302 is fixedly connected to the crankshaft 304. The servo motor 302 drives the crankshaft 304 to rotate, and then the wooden board 8 is staggered and lifted up, so that the second scraper 305 can smoothly scrape the gap.
[0050] It also includes a second baffle 306; the second baffle 306 is fixedly connected inside the second receiving tube 303; the second baffle 306 is located in front of the crankshaft 304; the second baffle 306 has several scraping grooves 30601, and each scraping groove 30601 is located in front of the adjacent second scraper 305; each scraping groove 30601 is set as an arc shape with a larger opening on the lower side and a smaller opening on the upper side; since the sawdust and dust scraped by the second scraper 305 carries glue, therefore, taking a view from right to left as a reference, when the crankshaft 304 drives the second scraper 305 to move in a clockwise direction... When the clock hand rotates, the second scraper 305 is guided to the upper opening after passing through the lower opening of the scraper groove 30601. Since the upper opening is smaller than the lower opening, the wood chips and dust carrying glue remaining on the second scraper 305 will be blocked under the second baffle 306 and fall into the second collection tube 303. This effectively prevents the wood chips and dust carrying glue from adhering to the gap between the upper wooden boards 8 when the crankshaft 304 drives the second scraper 305 to rotate, thus avoiding reducing the bonding strength between the wooden boards 8 and affecting product quality.
[0051] Example 4
