Description

Technical Field

[0001] This invention belongs to the field of adhesive coating equipment technology, and particularly relates to an automated and efficient adhesive coating device for plastic products. Background Technology

[0002] In the manufacturing process of plastic products, in order to meet specific functional requirements such as assembly and connection, sealing and leak prevention, shock absorption and cushioning, or marking and decoration, it is usually necessary to apply glue to their surface, which places extremely high demands on the precision and consistency of the glue application process.

[0003] According to Chinese Patent Publication No. CN116061276A, a plywood gluing device is disclosed, comprising: a feeding assembly, a gluing assembly, a counter, a controller, and a discharging assembly. The feeding assembly, gluing assembly, and discharging assembly are connected sequentially. The gluing assembly includes two mounting frames, a gluing device, an adjusting roller group, and two second rolling rollers. The gluing device is disposed between the two mounting frames. The adjusting roller group is movably disposed directly below the gluing assembly. The two second rolling rollers are disposed on both sides of the adjusting roller group. The counter is disposed at the discharge end of the gluing assembly. The controller is disposed on the gluing assembly. The adjusting roller group and the counter are respectively connected to the controller. The controller is used to adjust the adjusting roller group according to the counter's count.

[0004] However, in the above solution, the coating width of the coating roller is fixed, which leads to the following disadvantages: it cannot adapt to plastic parts of different widths, resulting in the coating area being larger or smaller than the coating surface of the plastic part, thus reducing the coating quality. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that the coating area is either too large or too small to accommodate plastic parts of different widths, resulting in a reduced coating quality. Therefore, this invention proposes an automated and efficient coating device for plastic products.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated and efficient adhesive coating device for plastic products includes a dispensing box and an adhesive coating roller, wherein the adhesive coating roller is rotatably disposed below the dispensing box, and further includes:

[0008] Two piston plates are slidably disposed at both ends inside the dispensing box;

[0009] Multiple dispensing nozzles are arranged in an array on the bottom surface of the dispensing box along the length of the dispensing box, and the bottom ends of the dispensing nozzles are in contact with the top surface of the coating roller.

[0010] Preferred options also include:

[0011] A miniature air pump is installed on the outer wall of the distribution box;

[0012] Two connecting pipes connect to both sides of the micro air pump. The other end of the connecting pipe is connected to the distribution box, and the end of the connecting pipe away from the micro air pump is located between the piston plate and the side wall of the distribution box.

[0013] Two tension springs are symmetrically arranged at both ends of the inside of the distribution box, and the two ends of the tension springs are respectively connected to the piston plate and the side wall of the distribution box.

[0014] Preferred options also include:

[0015] Two connecting plates are fixed to the bottom ends of the distribution box, and the glue-applying roller is rotatably disposed between the two connecting plates via a rotating shaft.

[0016] The fixed motor is installed on one side of the connecting plate, and the output shaft of the fixed motor is connected to one end of the rotating shaft.

[0017] Preferred options also include:

[0018] Two rotating shafts are symmetrically connected inside the coating roller;

[0019] Two sets of eccentric hammers are fixed on two rotating shafts respectively. Each set of eccentric hammers consists of multiple eccentric hammers arranged in an array along the length of the rotating shaft.

[0020] Preferred options also include:

[0021] The fixing ring is fixed to the side wall of the connecting plate;

[0022] A transmission gear is installed at the end of a rotating shaft, and the transmission gear meshes with the inner wall of a fixed gear ring.

[0023] Preferred options also include:

[0024] A conveyor chain is positioned below the coating roller;

[0025] A support plate is fixed to the top surface of the conveyor chain plate, and the support plate has a U-shaped structure;

[0026] The sliding rod is slidably mounted on the side wall of the support plate;

[0027] The trigger wheel is connected to the end of the sliding rod located outside the support plate;

[0028] The trigger plate is located on one side of the conveyor chain plate;

[0029] A reset spring is located between the side wall of the support plate and the trigger wheel;

[0030] A clamping assembly, which is fixed to one end of the sliding rod located inside the support plate.

[0031] Preferably, the clamping assembly includes:

[0032] The assembly block is fixed to one end of the sliding rod located inside the support plate.

[0033] The clamping module is detachably connected to the assembly block.

[0034] Preferred options also include:

[0035] The guide cylinder is fixed on the inner wall of the support plate, and the sliding rod is slidably disposed inside the guide cylinder.

[0036] Preferred options also include:

[0037] A movable push rod, the bottom end of which is connected to the top surface of the distribution box, and a fixed bracket is fixedly connected to the top end of the movable push rod;

[0038] A conveying pipe, the bottom end of which is connected to a distribution box;

[0039] The storage box is fixed on the top surface of the fixed bracket, and the interior of the storage box is connected to the top of the delivery pump and delivery pipe.

[0040] Compared with existing technologies, the automated and efficient glue coating device for plastic products that adopts the above technical solution has the following beneficial effects:

[0041] 1. In this invention, the piston plate can be driven to move left and right in the distribution box by the coordinated operation of a micro air pump and a tension spring. This allows the relative position of the piston plate in the distribution box to be changed, realizing flexible adjustment of the number of connected distribution nozzles. This enables the adhesive spraying width on the surface of the coating roller to be adjusted in real time according to the actual width of the plastic part, ensuring that the adhesive layer is precisely matched with the surface of the plastic part. This effectively avoids adhesive waste and edge contamination, and improves the accuracy and adaptability of the coating operation.

[0042] 2. In this invention, the symmetrical vibration force generated by the high-speed rotation of eccentric hammers symmetrically arranged on both sides not only ensures that the adhesive can be fully and evenly adhered to the surface of the coating roller, avoiding uneven adhesion from affecting the subsequent coating effect, but also, after the coating roller descends and adheres to the plastic part, the continuous vibration generated by the eccentric hammers can effectively act on the coating surface of the plastic part while the plastic part moves along the conveyor belt to cooperate with the rotation of the coating roller to complete the coating, thereby achieving vibration combing of the adhesive, improving the uniformity and adhesion of the coating, and thus comprehensively optimizing the coating quality and production efficiency of the plastic part.

[0043] 3. In this invention, the cooperation between the trigger wheel and the trigger plate enables the sliding rod to drive the assembly block and the clamping module to move in opposite directions, thereby achieving automatic centering and stable clamping of the plastic parts. This effectively ensures the positional accuracy of the adhesive surface of the plastic parts during the adhesive application process and avoids adhesive quality defects caused by workpiece displacement. By adopting a replaceable clamping module design, and with the option to adapt to arc-shaped clamping modules, rectangular clamping modules, and special-shaped clamping modules, the device can flexibly adapt to plastic parts of different shapes.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0054] Please see Figures 1-6 The present invention provides a technical solution:

[0055] An automated and efficient adhesive coating device for plastic products includes a dispensing box 705 and an adhesive coating roller 701, wherein the adhesive coating roller 701 is rotatably disposed below the dispensing box 705, and further includes:

[0056] Movable push rod 1, the bottom end of which is connected to the top surface of the distribution box 705, and the top end of which is fixedly connected to a fixed bracket 5;

[0057] The conveying pipe 4 is telescopic, and its bottom end is connected to the distribution box 705.

[0058] Storage box 6, with an addition port on the top, is fixed to the top surface of the fixing bracket 5. The interior of the storage box 6 is connected to the top of the delivery pump and the delivery pipe 4.

[0059] Two piston plates 708 are slidably disposed at both ends of the inner interior of the distribution box 705. The cross-sectional shape of the piston plates 708 and the distribution box 705 is rectangular.

[0060] Multiple dispensing nozzles 702 are arranged in an array on the bottom surface of the dispensing box 705 along the length of the dispensing box 705, and the bottom ends of the dispensing nozzles 702 are in contact with the top surface of the coating roller 701.

[0061] Miniature air pump 704 is installed on the outer wall of distribution box 705;

[0062] Two connecting pipes 703 are connected to both sides of the micro air pump 704. The other end of the connecting pipe 703 is connected to the distribution box 705, and the end of the connecting pipe 703 away from the micro air pump 704 is located between the piston plate 708 and the side wall of the distribution box 705.

[0063] Two tension springs 707 are symmetrically arranged at both ends of the inside of the distribution box 705, and the two ends of the tension springs 707 are respectively connected to the piston plate 708 and the side wall of the distribution box 705;

[0064] Two connecting plates are fixed to the bottom ends of the dispensing box 705, and the glue-applying roller 701 is rotatably disposed between the two connecting plates via a rotating shaft;

[0065] A fixed motor 706 is mounted on one side of the connecting plate, and the output shaft of the fixed motor 706 is connected to one end of the rotating shaft.

[0066] Two rotating shafts 712 are symmetrically connected to the glue-applying roller 701.

[0067] Two sets of eccentric hammers 711 are fixed on two rotating shafts 712 respectively. Each set of eccentric hammers 711 consists of multiple eccentric hammers 711 arranged in an array along the length of the rotating shaft 712.

[0068] Two fixed toothed rings 709 are fixedly connected to the side wall of the connecting plate;

[0069] Two sets of transmission gears 710, each set of transmission gears 710 consists of two symmetrically arranged transmission gears 710, which are installed at the end of the rotating shaft 712. The transmission gears 710 mesh with the inner wall of the fixed gear ring 709.

[0070] The specific usage method and working principle are as follows: The staff controls the drive motor, which drives the transmission roller to rotate. The transmission roller drives the conveyor chain plate 3 to run. The conveyor chain plate 3 drives the support plate 201 to move in an orderly manner. The staff places the plastic parts on the support plate 201, so that the support plate 201 drives the plastic parts to move directly under the fixed bracket 5.

[0071] When the plastic part is located directly below the fixed bracket 5 and the coating roller 701, the micro air pump 704 delivers gas between the piston plate 708 and the inner wall of the distribution box 705 through the connecting pipe 703, causing the piston plate 708 to move towards the center of the distribution box 705. When the micro air pump 704 draws air, the tension spring 707 drives the piston plate 708 to move towards the end of the distribution box 705. By adjusting the position of the piston plate 708, the number of connections between the distribution nozzle 702 and the distribution box 705 is changed, thereby changing the spraying width of the distribution nozzle 702 on the coating roller 701, so that the width of the glue on the surface of the coating roller 701 matches the width of the plastic part below.

[0072] Afterwards, the delivery pump, in conjunction with the delivery pipe 4, extracts the colloid from the storage tank 6. The colloid is then sprayed onto the surface of the coating roller 701 through the distribution box 705 and the distribution nozzle 702. During this process, the fixed motor 706 drives the coating roller 701 to rotate. The coating roller 701 drives the two internal rotating shafts 712 to rotate. The rotating shafts 712 drive the two transmission gears 710 on both sides to revolve within the fixed gear ring 709. The meshing between the transmission gears 710 and the fixed gears causes the transmission gears 710 to rotate. The transmission gears 710 drive the rotating shafts 712 to rotate. The rotating shafts 712 drive multiple eccentric hammers 711 to rotate. The two sets of symmetrically arranged eccentric hammers 711 generate symmetrical vibration force through their own rotation, which allows the colloid to adhere more evenly to the surface of the coating roller 701, improving the uniformity of the coating.

[0073] Subsequently, the movable push rod 1 drives the distribution box 705 to move downwards. The distribution box 705 drives the glue-applying roller 701 to move downwards through the connecting plate, so that the glue-applying roller 701 is in contact with the glue-applying surface of the plastic part. The conveyor chain plate 3 drives the plastic part to move, and the glue-applying roller 701 completes the glue application on the plastic part. During this process, the vibration generated by the eccentric hammer 711 can act on the glue-applying surface of the plastic part, so as to vibrate and comb the plastic part while applying glue, ensuring the uniformity of glue application.

[0074] Please see Figures 1-2 and Figures 7-8 It also includes:

[0075] The conveyor chain plate 3 is located below the glue coating roller 701;

[0076] Two side supports are symmetrically arranged on both sides of the conveyor chain plate 3, and multiple transmission rollers are rotatably connected between the two side supports. The transmission rollers are connected to the conveyor chain plate 3 in a transmission connection.

[0077] A drive motor is mounted on one side of one of the side brackets via a mounting base, and one end of the output shaft of the drive motor extends to the other side of the side bracket and is connected to one side of one of the transmission rollers.

[0078] Multiple support plates 201 are arranged in a linear array along the length of the conveyor chain plate 3 and fixed on the top surface of the conveyor chain plate 3. The support plates 201 have a U-shaped structure.

[0079] Multiple sets of sliding rods 205, each set of sliding rods 205 consists of two symmetrically arranged sliding rods 205, which are slidably arranged on the side wall of the support plate 201;

[0080] Multiple sets of trigger wheels 203, each set of trigger wheels 203 consists of two pairs of trigger wheels 203, connected to the end of the sliding rod 205 located outside the support plate 201;

[0081] Two trigger plates 202 are symmetrically arranged above the conveyor chain plate 3 and on one side of the conveyor chain plate 3;

[0082] Multiple sets of return springs 204, each set of return springs 204 consists of two pairs of return springs 204, which are disposed between the side wall of the support plate 201 and the trigger wheel 203;

[0083] Multiple sets of guide cylinders 206, each set of guide cylinders 206 consists of two pairs of guide cylinders 206, fixed on the inner side wall of the support plate 201, and the sliding rod 205 is slidably disposed inside the guide cylinder 206;

[0084] Multiple clamping assemblies are fixed to one end of the sliding rod 205 located inside the support plate 201;

[0085] The clamping assembly includes:

[0086] Two assembly blocks 207 are symmetrically slidably connected above the support plate 201, and the assembly blocks 207 are fixed to one end of the sliding rod 205 located inside the support plate 201.

[0087] Two clamping modules 208 are detachably connected to the corresponding assembly blocks 207.

[0088] The specific usage method and working principle are as follows: During the feeding process, the worker places the plastic part with the glued surface facing up on the support plate 201. The support plate 201, driven by the conveyor chain plate 3, moves the plastic part towards the fixed bracket 5. When the support plate 201 approaches the fixed bracket 5, the trigger wheel 203 gradually comes into contact with the trigger plate 202. The trigger wheel 203 moves under the drive of the trigger plate 202. The two trigger wheels 203 drive the two sliding rods 205 to move synchronously in opposite directions. The sliding rods 205 drive the assembly block 207 to move synchronously. Assembly block 207 drives clamping module 208 to move relative to each other, clamping module 208 completes stable clamping of plastic parts, thereby ensuring the stability of the glued surface of plastic parts during glue application; when support plate 201 moves away from fixed bracket 5, trigger plate 202 releases the limit on trigger wheel 203, so that trigger wheel 203 is reset and moved under the drive of reset spring 204. Trigger wheel 203 drives assembly block 207 to move through sliding rod 205. Assembly block 207 drives clamping module 208 to release the clamping limit on plastic parts, making it convenient for workers to pick up materials later;

[0089] like Figure 8 As shown, from left to right, there are arc-shaped clamping modules, rectangular clamping modules, and special-shaped clamping modules. Clamping modules 208 are bolted to assembly blocks 207. In practical use, workers can remove the bolts to replace different types of clamping modules 208, thus adapting to different types of plastic parts.
