Description

Technical Field

[0001] This utility model relates to the field of bamboo board processing technology, and in particular to a surface glue removal machine for bamboo boards. Background Technology

[0002] Bamboo boards are made by gluing and pressing bamboo strips, bamboo stalks, or bamboo fibers together. They retain the natural texture and mechanical properties of bamboo. Bamboo has a short growth cycle and is a high-quality substitute for wood. It is renewable and biodegradable. The bamboo board surface glue remover is a special equipment for efficiently removing the glue layer remaining on the surface of bamboo boards during production or processing.

[0003] Existing adhesive removal machines for bamboo boards still have some problems. During the adhesive removal process using copper wire rollers, the strong adhesion of the adhesive and the smooth surface lead to incomplete adhesive removal, low efficiency, and adhesive residue. Therefore, those skilled in the art have provided an adhesive removal machine for bamboo boards to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surface adhesive removal machine for bamboo boards. Through the micro-nano rough structure formed by cone piercing, the mechanical locking points on the surface of the bamboo board are significantly improved, greatly enhancing the friction between the copper wire roller and the adhesive, thereby more effectively peeling off the adhesive layer. At the same time, the enhanced surface roughness can reduce the relative sliding between the copper wire roller and the adhesive, avoiding slippage and improving the uniformity and stability of adhesive removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bamboo board surface glue removal machine, including a support frame, a pretreatment structure at the upper front of the support frame, and a collection structure at the lower part of the support frame; The pretreatment structure includes two drive rods arranged vertically. A heating wire is fixedly connected to the center of each drive rod, and a conductive slip ring is fixedly connected to one end of each heating wire. Multiple conical spikes are fixedly connected to the outer walls of each drive rod. One end of the lower drive rod passes through the inner wall of the bracket and extends to one side of the bracket, and a third servo motor is fixedly connected to its end. The third servo motor is fixedly connected to one side wall of the bracket. Through the above technical solution, the third servo motor drives the lower drive rod to rotate, causing the lower drive rod to move the bamboo board into the support. During the movement, the conical spikes on the surface of the two drive rods pierce the glue on the surface of the bamboo board, creating multiple holes in the glue. This increases the friction between the glue and the two copper wire rods, thus more effectively peeling off the glue layer. At the same time, the increased surface roughness reduces the relative slippage between the copper wire rods and the glue, avoiding slippage and improving the uniformity and stability of glue removal. Furthermore, the conductive slip ring 209 supplies power to the heating wire 202, heating and piercing simultaneously, causing the glue to soften due to heat and significantly reducing its adhesion. Combined with the piercing action, the glue layer is more easily mechanically peeled off, reducing residue.

[0006] Furthermore, four first sliding grooves are arranged in a front-to-back pattern on both sides of the upper end face of the bracket. Each of the eight first sliding grooves is slidably connected to a first slider. Each of the eight first sliders is fixedly connected to a first compression spring at its upper end. Each of the eight first sliding grooves is fixedly connected to a first top plate on the upper end face of the bracket. A shaft is arranged vertically between the two horizontal first sliders at the front and between the two horizontal first sliders at the rear. One end of the shaft at the lower rear end passes through the inner side wall of the bracket and extends to one side of the bracket. A second servo motor is fixedly connected to the end of the shaft. The second servo motor is fixedly connected to one side wall of the bracket. Through the above technical solution, eight first compression springs press eight first sliders to move downwards, and the eight first sliders drive the four upper shafts and the upper copper wire rod to move downwards.

[0007] Furthermore, the collection structure includes a base block, which is fixedly connected to the lower inner wall of the support. A groove is provided at the center of the upper end face of the base block, and a storage box is slidably connected inside the groove. A handle is fixedly connected to the center of one side wall of the storage box. A collection hopper is fixedly connected inside the upper support of the storage box, and a leakage hole is provided at the center of the lower inner wall of the collection hopper. With the above technical solution, the debris at the bottom is collected by the collection hopper and falls into the storage box through the hole. The storage box can be slid along the groove by pulling out the handle, which facilitates the collection and processing of debris.

[0008] Furthermore, two copper wire rods are arranged vertically at the upper center of the bracket. One end of each copper wire rod passes through the inner wall of the bracket and extends to one side of the bracket. A first pulley is fixedly connected to each end. A first servo motor is fixedly connected to the lower side of the front face and the lower side of the rear face of the bracket. A second pulley is fixedly connected to the output end of each of the two first servo motors. A transmission belt is fitted on the outer side of each of the two first pulleys and the two second pulleys. Through the above technical solution, the two second pulleys at the output ends of the two first servo motors drive the two first pulleys to rotate via a transmission belt, thereby driving the two copper screws to rotate.

[0009] Furthermore, a second sliding groove is provided on the upper end surface of the brackets on both sides of the drive rod near the top, and a second slider is slidably connected inside the two second sliding grooves. A second compression spring is fixedly connected at the center of the upper end surface of the two second sliders, and a second top plate is fixedly connected on the upper end surface of the brackets at the top of the two second sliders. The above technical solution facilitates the downward movement of the second slider by the second compression spring, allowing the second slider to slide down along the second groove, and making it easier for the upper drive rod to press the bamboo board.

[0010] Furthermore, side shells are provided on both sides of the support, and gas collection hoods are fixedly connected to the upper ends of the two side shells. A placement rack is fixedly connected to the lower center of the front face of the support. With the above technical solution, when using it, the bamboo board is placed on the rack and pushed to the rear. Before use, the dust is collected by connecting the vacuum cleaner to the air collection hood.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the micro-nano rough structure formed by the cone piercing significantly increases the mechanical locking points on the surface of the bamboo board, greatly enhancing the friction between the copper wire roller and the adhesive, thereby more effectively peeling off the adhesive layer.

[0015] 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.

[0016] Reference Figure 1-4 One embodiment of this utility model is a bamboo board surface glue removal machine, which includes a support 1, a pretreatment structure 2 at the upper front of the support 1, and a collection structure 3 at the lower part of the support 1.

[0017] like Figure 1 , 2As shown in Figures 3 and 4, the pretreatment structure 2 includes two drive rods 201 arranged vertically. A heating wire 202 is fixedly connected to the center of each drive rod 201, and a conductive slip ring 209 is fixedly connected to one end of each heating wire 202. Multiple conical spikes 203 are fixedly connected to the outer walls of each drive rod 201. One end of the lower drive rod 201 penetrates the inner wall of the bracket 1 and extends to one side of the bracket 1, with a third servo motor 204 fixedly connected to its end. The third servo motor 204 is fixedly connected to one side wall of the bracket 1, and drives the lower drive rod 201 to rotate, causing the lower drive rod 201 to rotate. 01 drives the bamboo board to move into the support 1. During the movement, the cones 203 on the surface of the two drive rods 201 pierce the glue on the surface of the bamboo board, creating multiple holes in the glue. This increases the friction between the glue and the two copper wire rods 8, thus more effectively peeling off the glue layer. At the same time, the increased surface roughness reduces the relative sliding between the copper wire rods 8 and the glue, avoiding slippage and improving the uniformity and stability of glue removal. The heating wire 202 is powered by the conductive slip ring 209, and the glue is heated and pierced simultaneously, causing the glue to soften and significantly reducing its adhesion. At this time, combined with the piercing action, the glue layer is more easily mechanically peeled off, reducing residue.

[0018] Four first sliding grooves 14 are arranged back-to-back on both sides of the upper end face of the bracket 1. Each of the eight first sliding grooves 14 is slidably connected to a first slider 15. Each of the eight first sliders 15 is fixedly connected to a first compression spring 13. Each of the eight first sliding grooves 14 is fixedly connected to a first top plate 16 on the upper end face of the bracket 1. A shaft 9 is arranged vertically between the two horizontal first sliders 15 at the front and between the two horizontal first sliders 15 at the rear. One end of the shaft 9 at the lower rear end passes through the inner wall of the bracket 1 and extends to one side of the bracket 1. A second servo motor 10 is fixedly connected to the end of the shaft 9. The second servo motor 10 is fixedly connected to one side wall of the bracket 1. The eight first compression springs 13 compress the eight first sliders 15 to move downward. The eight first sliders 15 drive the four shafts 9 and the copper wire rod 8 at the upper end to move downward.

[0019] like Figure 1 , 2As shown in Figures 3 and 4, the collecting structure 3 includes a base block 302, which is fixedly connected to the lower inner wall of the support 1. A groove 303 is provided at the center of the upper surface of the base block 302. A storage box 304 is slidably connected inside the groove 303. A handle 301 is fixedly connected to the center of one side wall of the storage box 304. A collecting hopper 305 is fixedly connected to the inside of the support 1 at the upper end of the storage box 304. A drain hole 306 is provided at the center of the lower inner wall of the collecting hopper 305. The debris at the lower end is collected through the collecting hopper 305 and falls into the storage box 304 through the drain hole 306. The storage box 304 can be pulled out by the handle 301, so that the storage box 304 slides along the groove 303, which facilitates the collection and processing of debris.

[0020] Two copper wire rods 8 are arranged vertically at the upper center of the bracket 1. One end of each copper wire rod 8 passes through the inner wall of the bracket 1 and extends to one side of the bracket 1. A first pulley 11 is fixedly connected to each end of the bracket 1. A first servo motor 5 is fixedly connected to the lower side of the front face and the lower side of the rear face of the bracket 1. A second pulley 12 is fixedly connected to the output end of each of the two first servo motors 5. A transmission belt is fitted on the outer side of each of the two first pulleys 11 and the two second pulleys 12. The two second pulleys 12 at the output end of the two first servo motors 5 drive the two first pulleys 11 to rotate through the transmission belt, thereby driving the two copper wire rods 8 to rotate.

[0021] A second slide groove 207 is provided on the upper end surface of the bracket 1 on both sides of the upper drive rod 201. A second slider 206 is slidably connected inside the two second slide grooves 207. A second compression spring 205 is fixedly connected to the center of the upper end surface of the two second sliders 206. A second top plate 208 is fixedly connected to the upper end surface of the upper bracket 1 of the two second sliders 206. This facilitates the second slider 206 to move downward by being squeezed by the second compression spring 205, so that the second slider 206 slides downward along the second slide groove 207, making it easier for the upper drive rod 201 to squeeze the bamboo board.

[0022] The bracket 1 has side shells 4 on both sides of the side walls. The upper ends of the two side shells 4 are fixedly connected to the air collection hoods 7. The front face of the bracket 1 is fixedly connected to the lower center of the placement rack 6. When in use, the bamboo board is placed on the placement rack 6 and pushed to the rear. Before use, the vacuum cleaner is connected to the air collection hood 7 to facilitate the adsorption of dust during sanding.

[0023] Working principle: In use, the bamboo board is placed on the placement rack 6 and pushed to the rear, activating the two first servo motors 5, the second servo motor 10, and the third servo motor 204. The two second pulleys 12 at the output ends of the two first servo motors 5 drive the two first pulleys 11 to rotate via a transmission belt, thereby driving the two copper wire rods 8 to rotate. The second servo motor 10 drives the lower rear shaft 9 to rotate, and the third servo motor 204 drives the lower drive rod 201 to rotate, causing the lower drive rod 201 to move the bamboo board into the bracket 1. During the movement, the awls 203 on the surface of the two drive rods 201 puncture the glue on the surface of the bamboo board, creating multiple holes in the glue. This increases the friction between the two copper wire rods 8, thereby more effectively peeling off the adhesive layer. At the same time, the enhanced surface roughness reduces the relative sliding between the copper wire rods 8 and the adhesive, avoiding slippage and improving the uniformity and stability of adhesive removal. The heating wire 202 is powered by the conductive slip ring 209, and the adhesive is heated and pierced simultaneously, causing the adhesive to soften and significantly reducing its adhesion. At this time, combined with the piercing action, the adhesive layer is more easily mechanically peeled off, reducing residue. The surface temperature of the heating wire 202 is monitored in real time by a temperature sensor and fed back to the PID controller to dynamically adjust the thyristor conduction angle or pulse width modulation to maintain the temperature stable at the set value. This is a commonly used technical solution in existing temperature control systems and will not be elaborated on further here.

[0024] When entering the rear end, the bamboo and wooden boards after sanding are discharged by rotating the shaft 9. Before use, the dust during sanding is easily absorbed by connecting the vacuum cleaner to the air collection hood 7. The debris at the bottom is collected by the collection hopper 305 and falls into the storage box 304 through the hole 306. The storage box 304 is pulled out by the handle 301 and slides along the groove 303 to facilitate the collection and processing of debris.

[0025] The equipment includes a control panel, which enables the equipment to be started and controlled through a human-machine interface and an electrical control system. Input signal processing converts the operator's instructions into electrical signals, and output signal transmission transmits the control signals to each actuator to achieve the above-mentioned equipment control. This is a commonly used technical solution in existing glue removal machine control systems, and will not be elaborated on further here.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
