Description

Technical Field

[0001] This invention belongs to the technical field of plywood production equipment, specifically referring to a glue applicator with a glue roller status monitoring function. Background Technology

[0002] Plywood gluing machines are key equipment in plywood production. They are used to evenly apply adhesives (such as urea-formaldehyde resin, phenolic resin, etc.) to the surface of veneers (thin wood veneers) for subsequent hot pressing. They consist of components such as gluing rollers and extrusion rollers, and the adhesive is evenly transferred to the surface of the veneer by rotating the rollers.

[0003] In actual production, due to the quality of the veneer, when the glue roller contacts the veneer for glue application, the veneer is subjected to pressure, which can easily cause wood chips to fall off. The fallen wood chips adhere to the surface of the glue roller, resulting in an uneven surface. Existing glue application machines lack online monitoring of the glue roller, making it impossible to monitor the condition of the glue roller in a timely manner. This makes it easy to cause uneven glue application in subsequent glue application. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a glue applicator with glue roller status monitoring function, which at least partially solves the above problems.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a glue applicator with a glue roller status monitoring function, comprising: The machine is equipped with two symmetrically arranged glue-applying rollers. On each of the two glue-applying rollers, there is an auxiliary roller on the horizontal side. There is a glue storage gap between the glue-applying roller and the auxiliary roller for storing glue. A drive unit is used to drive the coating roller and the auxiliary roller to rotate respectively; The glue storage gap is provided with a glue scoop, the top of the glue scoop is provided with an opening, and one end of the glue scoop is provided with a first motor for driving the glue scoop to rotate, so that the opening of the glue scoop can contact or detach from the glue coating roller. The shovel bucket is equipped with a conveying auger inside, and one end of the shovel bucket is equipped with a discharge pipe that is coaxial with the conveying auger and used for discharging slag.

[0006] Furthermore, a monitoring roller is provided in the glue storage gap to contact the glue coating roller. The monitoring roller is located above the glue scoop and is configured to move elastically along the radial direction of the glue coating roller. Monitoring units are provided at both ends of the monitoring roller to monitor the displacement distance of the monitoring roller.

[0007] Furthermore, the monitoring roller is the same length as the coating roller.

[0008] Furthermore, the monitoring roller includes a rigid roller and a rubber roller sleeve, the rubber roller sleeve being wrapped around the outside of the rigid roller.

[0009] Furthermore, the monitoring unit includes a sliding frame, a slider, and a distance sensor. The sliding frame is fixed on the machine base, the slider slides inside the sliding frame, and the two ends of the monitoring roller are respectively rotatably connected to the slider at corresponding positions. One end of the sliding frame is provided with a distance sensor for monitoring the displacement distance of the slider.

[0010] Furthermore, the monitoring unit also includes a spring, one end of which is connected to the slider and the other end of which is connected to the sliding frame.

[0011] Furthermore, a second motor for driving the conveying auger is provided at one end of the glue storage gap, and the second motor is connected to the machine platform.

[0012] Furthermore, a driven gear coaxial with the outer side of the discharge tube is fixed thereon, and a driving gear is provided on the output shaft of the first motor, the driving gear meshing with the driven gear.

[0013] Furthermore, the bottom of the shovel bucket is configured as a semi-circular tubular structure adapted to the diameter of the conveying auger.

[0014] Furthermore, the bottom of the machine is provided with a tray for receiving adhesive.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows: 1. By setting a flip-up glue hopper and flipping it so that the opening contacts the glue-applying roller, as the glue-applying roller rotates, the glue and wood chips on the glue-applying roller are scraped into the glue hopper. After being scraped, the glue-applying roller rotates into the glue storage gap, and the glue re-adheres onto the glue-applying roller. This can effectively remove wood chips from the glue roller and avoid uneven glue application.

[0016] 2. By setting a monitoring roller to monitor the status of the glue coating roller in real time, the presence of wood chips on the glue coating roller can be monitored in real time, thereby controlling whether the glue scoop contacts the glue coating roller to scrape glue. This precisely controls the contact time between the glue scoop and the glue coating roller, reducing the wear caused by friction between the glue scoop and the glue coating roller, and also avoiding the temperature rise of the glue coating roller caused by continuous friction during glue scraping.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] like Figure 1As shown, the present invention proposes a glue applicator with glue applicator roller status monitoring function, including a machine base 1, a glue applicator roller 2 and an auxiliary roller 3.

[0023] Two glue-applying rollers 2 are provided and are symmetrically arranged on the machine base 1. The two glue-applying rollers 2 can simultaneously apply glue to the upper and lower surfaces of the board. On the horizontal side of each of the two glue-applying rollers 2, there is an auxiliary roller 3. A glue storage gap 101 is provided between the glue-applying roller 2 and the auxiliary roller 3 for storing glue. The glue is stored in the glue storage gap 101 and is evenly adhered to the surface of the glue-applying roller 2 as the glue-applying roller 2 rotates, and is then applied to the board through the glue-applying roller 2.

[0024] The machine 1 is equipped with a drive unit, which drives both the glue-applying roller 2 and the auxiliary roller 3. The two glue-applying rollers 2 rotate in opposite directions, allowing the sheet material to be clamped by the two rollers and conveyed to one side (e.g., ...). Figure 4 (As shown).

[0025] Furthermore, the coating roller 2 and its corresponding auxiliary roller 3 rotate in opposite directions, and the coating roller 2 and auxiliary roller 3 rotate toward the glue storage gap 101, thereby squeezing the glue in the glue storage gap 101 downwards and allowing the glue to adhere to the coating roller 2 (e.g., Figure 4 (As shown).

[0026] Furthermore, the machine base 1 is equipped with horizontally and vertically arranged screw slides. The glue-applying roller 2 and the auxiliary roller 3 are respectively connected to the horizontally and vertically arranged screw slides, so that the vertical distance between the two glue-applying rollers 2 can be adjusted to adapt to different thicknesses of the board. At the same time, the horizontal distance between the glue-applying roller 2 and the auxiliary roller 3 can also be adjusted to adjust the glue thickness on the glue-applying roller 2.

[0027] In a specific embodiment, the drive unit includes a motor and a transmission gear set, and the transmission gear set includes multiple output shafts. The position and rotation direction of the output shafts correspond to the coating roller 2 and the auxiliary roller 3, respectively. The coating roller 2 and the auxiliary roller 3 are connected to the corresponding output shafts. The motor drives the transmission gear set to rotate, thereby driving the coating roller 2 and the auxiliary roller 3 to rotate.

[0028] Combination Figure 2 and Figure 3 As shown, a glue scoop 5 is provided in the glue storage gap 101. The top of the glue scoop 5 is provided with an opening. One end of the glue scoop 5 is provided with a first motor 6 for driving the glue scoop 5 to flip. The first motor 6 drives the glue scoop 5 to flip, so that the opening of the glue scoop 5 can contact or detach from the glue coating roller 2.

[0029] When the opening of the glue hopper 5 contacts the glue application roller 2, as the glue application roller 2 rotates, the glue and wood chips on the glue application roller 2 are scraped into the glue hopper 5. After being scraped, the glue application roller 2 rotates into the glue storage gap 101, and the glue re-adheres onto the glue application roller 2 (e.g., Figure 6 As shown in the figure, it can effectively remove wood chips from the glue roller and avoid uneven glue application caused by wood chips.

[0030] Furthermore, the inside of the glue scoop 5 is equipped with a conveying auger 51, and one end of the glue scoop 5 is equipped with a glue discharge pipe 52 that is coaxial with the conveying auger 51 and used for discharging slag. As the glue scoop 5 continues to scoop glue, the conveying auger 51 operates synchronously and conveys the glue and wood chips inside the glue scoop 5 to the glue discharge pipe 52, and discharges them through the glue discharge pipe 52, thus preventing the glue and wood chips inside the glue scoop 5 from accumulating and overflowing.

[0031] It should be noted that the glue discharge pipe 52 is connected to an external storage device through a pipeline, and the discharged glue and wood chips are transported to the external storage device for temporary storage, which facilitates subsequent unified processing.

[0032] In an optional embodiment, the bottom of the glue scoop 5 is configured as a semi-circular tubular structure that matches the diameter of the conveying auger 51, so that the conveying auger 51 can fit against the inner wall of the bottom of the glue scoop 5, thereby improving the glue discharge efficiency.

[0033] In a specific embodiment, a second motor 53 is provided at one end of the glue storage gap 101. The output shaft of the second motor 53 is connected to the conveying auger 51. The second motor 53 drives the conveying auger 51 to operate, and the second motor 53 is fixed to the machine base 1.

[0034] Combination Figure 2 and Figure 3 As shown, a driven gear 54 coaxial with the outer side of the glue discharge pipe 52 is fixed thereon. A driving gear 61 is provided on the output shaft of the first motor 6. The driving gear 61 meshes with the driven gear 54. The first motor 6 drives the driving gear 61 to rotate. The driving gear 61 drives the glue discharge pipe 52 to rotate through the driven gear 54. The glue scoop 5 connected to the glue discharge pipe 52 swings around the axis of the glue discharge pipe 52.

[0035] Understandably, since the discharge hose 52 needs to rotate, the pipe connecting the discharge hose 52 to the external storage device is a flexible hose.

[0036] Thus, the first motor 6 drives the glue hopper 5 to rotate, causing the opening of the glue hopper 5 to contact the glue application roller 2. As the glue application roller 2 rotates, the glue and wood chips on the glue application roller 2 are scraped into the glue hopper 5. After being scraped, the glue application roller 2 rotates into the glue storage gap 101, and the glue re-adheres onto the glue application roller 2 (e.g., ...). Figure 6As shown, it can effectively remove wood chips from the glue roller. After the glue is scraped by the glue scoop 5, the glue roller 2 passes through the glue storage gap 101 and re-attaches glue.

[0037] Meanwhile, as the glue scoop 5 continues to scoop glue, the conveying auger 51 operates synchronously, conveying the glue and wood chips inside the glue scoop 5 to the glue discharge pipe 52, and then discharges them through the glue discharge pipe 52 to an external storage device for temporary storage, thus preventing the glue and wood chips inside the glue scoop 5 from accumulating and overflowing.

[0038] Combination Figure 2 and Figure 3 As shown, a monitoring roller 4 is provided in the glue storage gap 101 to contact the glue application roller 2. The monitoring roller 4 is located above the glue scoop 5. When the glue application roller 2 rotates, it first contacts the monitoring roller 4, then passes through the glue scoop 5, and finally rotates to the glue storage gap 101. Therefore, before passing through the glue scoop 5, the glue application roller 2 contacts the monitoring roller 4. The monitoring roller 4 monitors in real time whether there is wood chips adhering above the glue application roller 2, and then controls whether the glue scoop 5 contacts the glue application roller 2 to scoop glue based on the detection results.

[0039] When the monitoring roller 4 detects no wood chips on the glue-applying roller 2, the glue scoop 5 does not contact the glue-applying roller 2. After passing through the glue scoop 5, the glue-applying roller 2 passes through the glue storage gap 101 and re-attaches glue. When the monitoring roller 4 detects wood chips on the glue-applying roller 2, the glue scoop 5 contacts the glue-applying roller 2. As the glue-applying roller 2 rotates, the glue and wood chips on the glue-applying roller 2 are scraped into the glue scoop 5, and then pass through the glue storage gap 101 and re-attach glue.

[0040] The monitoring roller 4 detects whether there is wood chips on the glue coating roller 2, thereby controlling whether the glue scraper 5 contacts the glue coating roller 2 to scrape glue. This precisely controls the contact time between the glue scraper 5 and the glue coating roller 2, reducing the wear caused by the contact friction between the glue scraper 5 and the glue coating roller 2, and at the same time avoiding the temperature rise of the glue coating roller 2 caused by continuous friction during glue scraping.

[0041] In a specific embodiment, the monitoring roller 4 is configured to move elastically along the radial direction of the coating roller 2. Monitoring units are provided at both ends of the monitoring roller 4 for real-time monitoring of the displacement distance of the monitoring roller 4. When there is no wood chips on the coating roller 2, the monitoring roller 4 will not jump radially. However, when there are wood chips on the coating roller 2, the wood chips are relatively hard. When the wood chips come into contact with the monitoring roller 4, the monitoring roller 4 will jump radially. At this time, the monitoring unit detects the displacement of the monitoring roller 4 and then controls the glue scoop 5 to flip so that the glue scoop 5 contacts the coating roller 2 to scoop glue.

[0042] Furthermore, the monitoring roller 4 is the same length as the coating roller 2, which allows the monitoring roller 4 to monitor the entire coating roller 2 and avoid monitoring blind spots.

[0043] In an optional embodiment, the monitoring roller 4 includes a rigid roller and a rubber roller sleeve. The rubber roller sleeve wraps around the outside of the rigid roller. The rigid roller can maintain the supporting rigidity of the monitoring roller 4, while the rubber roller sleeve is soft and can play a protective role to prevent wear of the coating roller 2.

[0044] Combination Figure 7 As shown, the monitoring unit includes a sliding frame 41, a slider 42, and a distance sensor 43. The sliding frame 41 is fixed on the machine base 1, and the slider 42 slides inside the sliding frame 41. The two ends of the monitoring roller 4 are rotatably connected to the slider 42 at the corresponding positions. One end of the sliding frame 41 is provided with a distance sensor 43 for monitoring the displacement distance of the slider 42.

[0045] When the monitoring roller 4 experiences radial runout, the sliders 42 at both ends of the monitoring roller 4 slide along the sliding frame 41. At this time, the distance sensor 43 detects the displacement of the sliders 42, thereby determining that there is wood chips adhering to the glue coating roller 2, and controls the glue scraper 5 to contact the glue coating roller 2 to scrape off the glue.

[0046] It should be noted that when the wood chips are no longer in contact with the monitoring roller 4 (i.e., the last time the monitoring roller 4 detects the wood chips), the glue scoop 5 is set to delay contact with the glue coating roller 2 for 10 seconds to ensure that the glue scoop 5 can completely remove the wood chips on the glue coating roller 2.

[0047] Furthermore, the monitoring unit also includes a spring 44, one end of which is connected to the slider 42 and the other end of which is connected to the sliding frame 41. The spring 44 applies tension to the monitoring roller 4 so that the monitoring roller 4 is always in contact with the glue coating roller 2.

[0048] Thus, under the tension of spring 44, the monitoring roller 4 always adheres to the glue-applying roller 2. When there is no wood chips on the glue-applying roller 2, the monitoring roller 4 will not run radially. However, when there are wood chips on the glue-applying roller 2, the wood chips are relatively hard. When the wood chips come into contact with the monitoring roller 4, the monitoring roller 4 will run radially. At the same time, the sliders 42 at both ends of the monitoring roller 4 slide along the sliding frame 41. At this time, the distance sensor 43 detects the displacement of the sliders 42, thereby determining that there are wood chips adhering to the glue-applying roller 2, and controls the glue-scraping bucket 5 to flip and contact the glue-applying roller 2 to scrape off the glue.

[0049] The monitoring roller 4 detects whether there is wood chips on the glue coating roller 2, thereby controlling whether the glue scraper 5 contacts the glue coating roller 2 to scrape glue. This precisely controls the contact time between the glue scraper 5 and the glue coating roller 2, reducing the wear caused by the contact friction between the glue scraper 5 and the glue coating roller 2, and at the same time avoiding the temperature rise of the glue coating roller 2 caused by continuous friction during glue scraping.

[0050] Combination Figure 1 As shown, the bottom of the machine 1 is equipped with a tray 7 for receiving glue. The glue dripping from the glue application roller 2 and the auxiliary roller 3 falls onto the tray 7, which facilitates subsequent centralized processing and avoids glue contamination of the workshop.

[0051] The working principle of this invention is as follows: Under the tension of spring 44, the monitoring roller 4 is always in contact with the glue coating roller 2. When there is no wood chips on the glue coating roller 2, the monitoring roller 4 will not experience radial movement. However, when there are wood chips on the glue coating roller 2, the wood chips are relatively hard, and when the wood chips come into contact with the monitoring roller 4, the monitoring roller 4 will experience radial movement. At the same time, the sliders 42 at both ends of the monitoring roller 4 slide along the sliding frame 41. At this time, the distance sensor 43 detects the displacement of the sliders 42, thereby determining that there are wood chips adhering to the glue coating roller 2, and controls the first motor 6 to operate. The first motor 6 drives the glue scraper 5 to rotate, so that the opening of the glue scraper 5 contacts the glue coating roller 2. As the glue coating roller 2 rotates, the glue and wood chips on the glue coating roller 2 are scraped into the glue scraper 5. After being scraped, the glue coating roller 2 rotates into the glue storage gap 101, and the glue re-adheres onto the glue coating roller 2 (e.g., Figure 6 As shown, it can effectively remove wood chips from the glue roller. After the glue is scraped by the glue scoop 5, the glue roller 2 passes through the glue storage gap 101 and re-attaches glue.

[0052] Meanwhile, as the glue scoop 5 continues to scoop glue, the conveying auger 51 operates synchronously, conveying the glue and wood chips inside the glue scoop 5 to the glue discharge pipe 52, and then discharges them through the glue discharge pipe 52 to an external storage device for temporary storage, thus preventing the glue and wood chips inside the glue scoop 5 from accumulating and overflowing.

[0053] In summary, by setting up a flip-up glue hopper 5 and flipping it so that its opening contacts the glue-applying roller 2, as the glue-applying roller 2 rotates, the glue and wood chips on the roller 2 are scraped into the glue hopper 5. After being scraped, the glue-applying roller 2 rotates into the glue storage gap 101, and the glue re-adheres onto the roller 2 (e.g., ...). Figure 6 As shown in the figure, it can effectively remove wood chips from the glue roller and avoid uneven glue application.

[0054] By setting a monitoring roller 4 to monitor the status of the glue coating roller 2 in real time, the presence of wood chips on the glue coating roller 2 is monitored, thereby controlling whether the glue scraper 5 contacts the glue coating roller 2 to scrape glue. The contact time between the glue scraper 5 and the glue coating roller 2 is precisely controlled, reducing the wear caused by the contact friction between the glue scraper 5 and the glue coating roller 2, and at the same time avoiding the temperature rise of the glue coating roller 2 caused by continuous friction scraping.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0056] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
