Description

Technical Field

[0001] This utility model relates to the field of adhesive processing technology, specifically an environmentally friendly adhesive extrusion device. Background Technology

[0002] Environmentally friendly adhesives are those that do not contain volatile substances or harmful substances such as formaldehyde. During processing, an extrusion device is used to squeeze the environmentally friendly adhesive into storage bottles. The extrusion device primarily uses a conveyor belt to transport the storage bottles. When the bottles reach the bottom of the nozzle, the environmentally friendly adhesive in the storage container is sprayed from the nozzle into the storage bottles for storage.

[0003] For example, Chinese patent CN222373605U discloses an extrusion device for processing environmentally friendly adhesives, including a processing table, a conveyor belt, a circular trough, and a support frame. The conveyor belt is located inside the processing table, and several sets of circular troughs begin outside the conveyor belt. The support frame is welded to the top of the processing table, and clamping mechanisms are provided on both sides of the processing table. An extrusion mechanism is provided on the top of the support frame. The clamping mechanism includes a fixed frame, an electric cylinder, a support rod, and pressure plates. Several sets of fixed frames are welded to both sides of the processing table, and the electric cylinder is located outside the fixed frame. One end of the support rod is fixedly connected to the output end of the electric cylinder. This extrusion device for processing environmentally friendly adhesives, by adjusting the position of the pressure plates on both sides of the processing table, can clamp the storage bottle at the top of the circular trough when the two sets of pressure plates are close together. This prevents the storage bottle from shaking when storing environmentally friendly adhesives, ensuring that the environmentally friendly adhesives are fully contained in the storage bottle and preventing leakage, thereby reducing the processing cost of environmentally friendly adhesives.

[0004] However, in practical applications, existing extrusion devices use multiple sets of electric cylinders to drive the clamping components on both sides, achieving clamping of the storage bottle through independent control. However, such structures require power components that match the number of clamping components, which not only increases the manufacturing cost and energy consumption of the equipment and causes resource waste, but also easily leads to asynchronous clamping actions on both sides due to the response differences of multiple sets of power components. When the clamping force is uneven, the storage bottle is prone to tilting or shaking. Especially during the glue injection process, the impact force may cause the storage bottle to shift, resulting in glue leakage, which affects product quality and increases processing costs. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an environmentally friendly glue extrusion device. This technical solution solves the problem mentioned in the background art where existing glue extrusion devices use multiple sets of electric cylinders to drive clamping components on both sides, achieving clamping of the storage bottle through independent control. However, such structures require power components that match the number of clamping components, which not only increases the manufacturing cost and energy consumption of the equipment, causing resource waste, but also easily leads to asynchronous clamping actions on both sides due to the response differences of multiple sets of power components. When the clamping force is uneven, the storage bottle is prone to tilting or shaking. Especially during the glue injection process, the impact force may cause the storage bottle to shift, resulting in glue leakage, which affects product quality and increases processing costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An environmentally friendly adhesive extrusion device includes a U-shaped frame with a conveying mechanism inside. Two U-shaped guide frames are fixedly connected to both sides of the U-shaped frame, and a C-shaped movable frame is slidably connected within the two U-shaped guide frames. A vertical plate is fixedly connected to one end of the upper horizontal plate of the C-shaped movable frame. Mounting plates are connected to opposite sides of the two vertical plates via elastic components. Clamping plates are detachably connected to opposite sides of the two mounting plates. A mounting frame is fixedly connected to the bottom of the two lower U-shaped guide frames. A first motor is fixedly connected to the middle of the mounting frame. A rotating plate is fixedly connected to the output end of the first motor. Transmission rods are hinged to the top of both ends of the rotating plate. The ends of the two transmission rods that are far apart from each other are respectively hinged to one end of the lower horizontal plate of the C-shaped movable frame on both sides. An extrusion mechanism is connected to the top of the U-shaped frame via a bracket.

[0008] Preferably, support legs are fixedly connected to the four corners of the bottom of the U-shaped frame, and a reinforcing crossbar is fixedly connected between two adjacent support legs. A flexible pad is fixedly connected to the bottom of the support legs.

[0009] Preferably, screws are fixedly connected to the four corners of the clamping plate near the mounting plate, and mounting holes adapted to the four screws are opened at the four corners of the mounting plate. Nuts located on the outside of the mounting plate are threaded onto the screws.

[0010] Preferably, the conveying mechanism includes a first rotating shaft rotatably connected to both ends inside the U-shaped frame, a transmission roller fixedly connected to the first rotating shaft, a conveyor belt sleeved on two of the transmission rollers, a plurality of equally spaced placement grooves on the outer surface of the conveyor belt, a plurality of equally spaced second rotating shafts rotatably connected inside the U-shaped frame, the plurality of second rotating shafts being located between two first rotating shafts, an auxiliary support roller fixedly connected to the outside of the second rotating shafts, a second motor fixedly connected to the outside of the U-shaped frame, and the output end of the second motor fixedly connected to one end of one of the first rotating shafts.

[0011] Preferably, the elastic component includes two guide rods fixedly connected to the side of the mounting plate away from the clamping plate. Both guide rods are slidably connected to adjacent vertical plates. The other ends of the two guide rods are fixedly connected to a connecting plate. A spring sleeved on the guide rod is fixedly connected between the connecting plate and the vertical plate.

[0012] Compared with the prior art, this utility model provides an environmentally friendly glue extrusion device, which has the following beneficial effects:

[0013] 1. This utility model uses a first motor to drive a rotating plate and a transmission rod, which drives the two C-shaped moving frames to slide synchronously along the U-shaped guide frame. Only one set of power components is needed to achieve symmetrical clamping of the storage bottle by the clamping plate, which reduces the number of power components, lowers the equipment manufacturing cost and energy consumption, avoids the problem of asynchronous clamping caused by the response difference of multiple sets of power components, effectively prevents the storage bottle from tilting or shaking, reduces glue leakage, and improves processing stability and glue utilization.

[0014] 2. This utility model connects the vertical plate and the mounting plate through an elastic component. During the clamping process, the buffering effect of the spring can avoid damage to the storage bottle due to excessive clamping force. At the same time, the clamping plate and the mounting plate are detachably connected by screws and nuts, which makes it easy to replace the appropriate clamping plate according to the storage bottle of different specifications, improves the adaptability of the equipment to different storage containers, and enhances production flexibility.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Example 1

[0022] Please refer to Figures 1 to 4 As shown, an environmentally friendly adhesive extrusion device includes a U-shaped frame 1. A conveying mechanism 2 is installed inside the U-shaped frame 1. Two U-shaped guide frames 3 are fixedly connected to the left and right sides of the U-shaped frame 1. A C-shaped moving frame 4 is slidably connected inside the two U-shaped guide frames 3. A vertical plate 5 is fixedly connected to one end of the upper horizontal plate of the C-shaped moving frame 4. Mounting plates 7 are connected to the opposite sides of the two vertical plates 5 through elastic components 6. Clamping plates 8 are detachably connected to the opposite sides of the two mounting plates 7. A mounting frame is fixedly connected to the bottom of the two U-shaped guide frames 3 located below. A first motor 9 is fixedly connected to the middle of the mounting frame. A rotating plate 10 is fixedly connected to the output end of the first motor 9. Transmission rods 11 are hinged to the top of both ends of the rotating plate 10. The ends of the two transmission rods 11 that are far apart from each other are respectively hinged to one end of the lower horizontal plate of the C-shaped moving frame 4 on both sides. An extrusion mechanism 12 is connected to the top of the U-shaped frame 1 through a bracket.

[0023] Those skilled in the art will understand that the U-shaped frame 1 provides support for the device. When the conveying mechanism 2 transports the storage bottle to below the extrusion mechanism 12, the first motor 9 drives the rotating plate 10 to rotate. Through the transmission rod 11, the C-shaped moving frames 4 on both sides slide synchronously in opposite directions along the U-shaped guide frame 3, so that the vertical plate 5, elastic component 6, and mounting plate 7 drive the clamping plate 8 to symmetrically clamp the storage bottle, and the extrusion mechanism 12 completes the glue injection. Synchronous clamping is achieved with only one set of power components, reducing the number of power components, lowering costs and energy consumption, and avoiding storage bottle tilting or glue leakage caused by asynchronous clamping.

[0024] Example 2

[0025] Furthermore, support legs 13 are fixedly connected to the four corners of the bottom of the U-shaped frame 1, and reinforcing crossbars 14 are fixedly connected between two adjacent support legs 13. Flexible pads 15 are fixedly connected to the bottom of the support legs 13.

[0026] Those skilled in the art will understand that the support leg 13 supports the U-shaped frame 1, the reinforcing crossbar 14 enhances support stability, and the flexible pad 15 buffers vibrations during operation. This improves the overall structural stability of the device, reduces the impact of vibration on clamping accuracy and glue application effect, and lowers equipment operating noise.

[0027] Example 3

[0028] Furthermore, screws 16 are fixedly connected to the four corners of the clamping plate 8 near the mounting plate 7. Mounting holes 17 are provided at the four corners of the mounting plate 7 to match the four screws 16 respectively. Nuts 18 located on the outside of the mounting plate 7 are threaded onto the screws 16.

[0029] Those skilled in the art will understand that the clamping plate 8 is fixed by a screw 16 passing through the mounting hole 17 of the mounting plate 7 and secured by a nut 18, achieving a detachable connection. This facilitates the replacement of the clamping plate 8 with a suitable one for storage bottles of different sizes, improving the equipment's adaptability to various containers and enhancing production flexibility.

[0030] Example 4

[0031] Furthermore, the conveying mechanism 2 includes a first rotating shaft 201 rotatably connected to both ends inside the U-shaped frame 1. A transmission roller 202 is fixedly connected to the first rotating shaft 201. A conveyor belt 203 is sleeved on both transmission rollers 202. The outer surface of the conveyor belt 203 is provided with several equally spaced placement grooves. Several equally spaced second rotating shafts 204 are also rotatably connected inside the U-shaped frame 1. The several second rotating shafts 204 are all located between two first rotating shafts 201. An auxiliary support roller 205 is fixedly connected to the outside of the second rotating shaft 204. A second motor 206 is fixedly connected to the outside of the U-shaped frame 1. The output end of the second motor 206 is fixedly connected to one end of one of the first rotating shafts 201.

[0032] Those skilled in the art will understand that the second motor 206 drives the first rotating shaft 201 and the transmission roller 202 to rotate, thereby driving the conveyor belt 203 to transport the storage bottles and positioning them in the placement slot. The auxiliary support roller 205 on the second rotating shaft 204 supports the conveyor belt 203 to prevent sagging. This ensures smooth transport of the storage bottles, avoids positioning deviations caused by deformation of the conveyor belt 203, and improves the accuracy of the dispensing position.

[0033] Example 5

[0034] Furthermore, the elastic component 6 includes two guide rods 601 fixedly connected to the side of the mounting plate 7 away from the clamping plate 8. Both guide rods 601 are slidably connected to the adjacent vertical plate 5. The other ends of the two guide rods 601 are fixedly connected to a connecting plate 602. A spring 603 sleeved on the guide rods 601 is fixedly connected between the connecting plate 602 and the vertical plate 5.

[0035] Those skilled in the art will understand that during clamping, the storage bottle presses against the clamping plate 8 and the mounting plate 7, pushing the guide rod 601 to slide along the vertical plate 5. The connecting plate 602 pulls up the spring 603, and the spring force of the spring 603 acts in the opposite direction to achieve buffering. By buffering the clamping force through the spring 603, the storage bottle is prevented from being deformed or broken due to excessive clamping, thus protecting the integrity of the container.

[0036] The working principle and usage procedure of this device are as follows: During use, the storage bottle is placed in the placement slot of the conveyor belt 203. The second motor 206 starts, driving the conveyor belt 203 through the first rotating shaft 201 and the transmission roller 202. The auxiliary support roller 205, supported by the second rotating shaft 204, prevents the conveyor belt 203 from sagging, ensuring the storage bottle is transported smoothly to below the extrusion mechanism 12. At this time, the first motor 9 drives the rotating plate 10 to rotate, which, via the transmission rod 11, drives the two C-shaped moving frames 4 to synchronously approach along the U-shaped guide frame 3, vertically... Plate 5 pushes mounting plate 7 and clamping plate 8 to clamp the storage bottle through elastic component 6. During the clamping process, spring 603 provides cushioning through guide rod 601 and connecting plate 602. The glue extrusion mechanism 12 injects glue into the storage bottle. After the glue injection is completed, the first motor 9 drives in reverse to release clamping plate 8. Conveyor belt 203 transports the storage bottle away. Support leg 13, reinforcing crossbar 14 and flexible pad 15 ensure stable operation of the equipment throughout the process. If the storage bottle specification needs to be changed, the clamping plate 8 can be disassembled and replaced with a suitable one through screw 16 and nut 18.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
