Description

Technical Field

[0001] The utility model relates to the technical field of polymer material preparation, in particular to a glue spraying device for polymer material preparation. Background Art

[0002] Polymer materials refer to materials based on high molecular compounds. They have relatively large molecular weights and have a variety of excellent properties, such as light specific gravity, high strength, good wear resistance, stable chemical properties, excellent corrosion resistance, etc. They have significant characteristics in terms of physical properties, chemical properties, and biological functions and are widely used in industries such as construction, transportation, agriculture, and the electrical and electronic industries. During the production and processing of some polymer material products, it is often necessary to use a corresponding glue spraying device to spray glue on the surface of the polymer materials.

[0003] For example, the utility model patent with the application number 202220245966.1 discloses a glue spraying device for polymer material preparation, including a base, a disc, a first motor, a bracket, and a glue spraying mechanism. The disc is rotatably connected to the upper surface of the base. The first motor is fixedly connected to the lower surface of the base, and the output shaft of the first motor is fixedly connected to the lower surface of the disc. The bracket is fixedly connected to the base, and the glue spraying mechanism is arranged on the bracket and is located directly above the disc.

[0004] Based on the prior art, it is found that most of the existing glue spraying devices for polymer material preparation have a single structure and cannot stably limit the polymer materials during the glue spraying process, resulting in a risk of offset of the polymer materials during the glue spraying process, thus affecting the glue spraying accuracy. Moreover, it is necessary to wait for the previous group of polymer materials to be sprayed and removed before installing new polymer materials to continue the glue spraying process, wasting unnecessary loading and unloading waiting time, unable to achieve continuous glue spraying, reducing the glue spraying efficiency, and having low practicability. Therefore, the utility model proposes a glue spraying device for polymer material preparation to solve the problems existing in the prior art. Summary of the Utility Model

[0005] Aiming at the above problems, the purpose of the utility model is to propose a glue spraying device for polymer material preparation, which solves the problems that the existing glue spraying devices for polymer material preparation cannot stably limit the polymer materials during the glue spraying process, resulting in a risk of offset of the polymer materials during the glue spraying process, and cannot achieve continuous glue spraying with low glue spraying efficiency.

[0006] To achieve the purpose of the present utility model, the present utility model is realized through the following technical solutions: A glue spraying device for preparing polymer materials, including a machine table, on the top of which symmetrically fixed support plates are provided. Between the two groups of support plates, a driving box is fixed. At the bottom of the driving box, a cylinder driven to displace by a gear driving mechanism is slidably provided. At the bottom of the cylinder, a glue spraying gun is fixed. On the top of the machine table, a moving plate driven to displace by a traction driving mechanism is slidably provided. On the top of the moving plate, turntables driven to rotate by motors are rotatably connected to the front and rear sides. On the top of the turntable, arc-shaped clamping plates driven to displace by a clamping mechanism are symmetrically provided. Between the two groups of arc-shaped clamping plates, a polymer material is clamped.

[0007] Further improvement lies in: The clamping mechanism includes a first motor fixed to the outer wall of the turntable and a bidirectional lead screw rotatably connected to the inside of the turntable and driven to rotate by the first motor. On both sides of the bidirectional lead screw, threaded blocks are threadedly sleeved. The top of the threaded block slidably penetrates through the top of the turntable and is fixed to the bottom of the arc-shaped clamping plate.

[0008] Further improvement lies in: The motor is fixed to the bottom end inside the moving plate. The output end of the motor penetrates through the top of the moving plate through a bearing and is fixed with a driving sprocket. On the top of the moving plate, a support shaft fixed to the bottom end of the turntable is rotatably connected. A driven sprocket is sleeved and fixed on the support shaft. A chain is commonly sleeved on the driving sprocket and the driven sprocket.

[0009] Further improvement lies in: The traction driving mechanism includes a rewinder fixed to the front and rear sides inside the machine table and a traction steel wire rope wound around the take-up reel at the output end of the rewinder. At the bottom of the moving plate, a traction plate slidably penetrating into the inside of the machine table is fixed. On the front and rear side walls of the traction plate, traction rings fixedly connected to the traction steel wire rope are fixed.

[0010] Further improvement lies in: On the left and right side walls of the traction plate, limit blocks slidably attached to the top end inside the machine table are fixed. On both sides of the top of the machine table, support rollers are rotatably connected and distributed at equal intervals.

[0011] Further improvement lies in: Below the turntable, a support ring fixed to the top of the moving plate is provided. On the top of the support ring, balls in contact with the bottom end of the turntable are symmetrically fixed.

[0012] Further improvement lies in: The gear driving mechanism includes a second motor fixed to the rear outer wall of the driving box and a rack located inside the driving box. The output end of the second motor penetrates through the bearing into the inside of the driving box and is fixed with a driving gear meshing with the rack. At the bottom of the rack, a slider is fixed. The bottom of the slider slidably penetrates through the bottom of the driving box and is fixed to the top of the cylinder.

[0013] The beneficial effects of the present utility model are as follows: The present utility model includes a machine table. Through a clamping mechanism, two arc-shaped clamping plates at the top of the turntable are driven to move towards each other, and the high molecular material to be spray-coated placed at the top of the turntable is clamped and fixed, so that the high molecular material is stably limited during the spray-coating process, avoiding deviation, ensuring the spray-coating treatment accuracy. And through a traction drive mechanism, a moving plate is driven to move back and forth at the top of the machine table, and the high molecular materials on the two turntables at its top are driven to move to the lower part of the drive box in turn for spray-coating treatment. Thus, when the high molecular material on one turntable is being spray-coated, a new high molecular material to be spray-coated can be reinstalled on the other turntable, saving unnecessary loading and unloading waiting time, enabling continuous spray-coating treatment of multiple groups of high molecular materials, and improving the spray-coating treatment efficiency to a certain extent.

[0020] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0021] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown in the figure, this embodiment provides a glue spraying device for preparing polymer materials, which includes a horizontally arranged machine table 1 and support plates 2 bolted to the left and right sides of the top of the machine table 1. A hollow driving box 3 is bolted between the two groups of support plates 2. A cylinder 4 is slidably arranged at the bottom of the driving box 3, and the cylinder 4 is driven by a gear driving mechanism and performs left and right lateral displacement at the bottom of the driving box 3. A glue spraying gun 5 for spraying glue on polymer materials is bolted to the bottom of the cylinder 4, and the glue spraying gun 5 is driven by the cylinder 4 to move up and down. A moving plate 6 designed in a rectangle is slidably arranged on the top of the machine table 1, and the moving plate 6 is driven by a traction driving mechanism and performs front and back longitudinal displacement on the top of the machine table 1. A motor 7 is bolted to the bottom end inside the moving plate 6. Rotating discs 8 are rotatably connected to the front and back sides of the top of the moving plate 6, and the two groups of rotating discs 8 are respectively driven by the two motors 7 to rotate, so as to drive the polymer materials on the top of the rotating discs 8 to rotate, enabling the glue spraying gun 5 to spray an annular glue circle on the surface of the polymer materials. The moving plate 6 is driven by the traction driving mechanism to move back and forth on the top of the machine table 1, and drives the polymer materials on the two rotating discs 8 at its top to move to the lower part of the driving box 3 in turn for glue spraying treatment. Thus, when the polymer materials on one of the rotating discs 8 are subjected to glue spraying treatment, new polymer materials to be subjected to glue spraying treatment can be reinstalled on the other rotating disc 8, saving unnecessary loading and unloading waiting time. Arc-shaped clamping plates 9 for limiting and clamping the polymer materials are symmetrically arranged on the top of the rotating disc 8, and the arc-shaped clamping plates 9 are driven by a clamping mechanism and move towards each other or in opposite directions on the top of the rotating disc 8. The polymer materials to be sprayed with glue are clamped between the two arc-shaped clamping plates 9. The two arc-shaped clamping plates 9 on the top of the rotating disc 8 are driven by the clamping mechanism to move towards each other, and the polymer materials to be sprayed with glue placed on the top of the rotating disc 8 are clamped and fixed, so that the polymer materials are stably limited during the glue spraying process.

[0022] The clamping mechanism includes a first motor 10 and a bidirectional lead screw 11. The first motor 10 is bolted to the outer side wall of the rotating disc 8. The bidirectional lead screw 11 is rotatably connected to the inside of the rotating disc 8 through a bearing. One end of the bidirectional lead screw 11 close to the first motor 10 penetrates through the outside of the rotating disc 8 through a bearing and is fixedly connected to the output shaft of the first motor 10. Threaded blocks 12 are threadedly sleeved on both sides of the bidirectional lead screw 11 and have opposite threading directions. The top ends of the threaded blocks 12 slide through the top of the rotating disc 8 and are bolted to the bottom ends of the arc-shaped clamping plates 9. The first motor 10 is started to drive the bidirectional lead screw 11 to rotate, so that the threaded blocks 12 threadedly sleeved on both sides of the bidirectional lead screw 11 move towards each other, and the two threaded blocks 12 drive the two arc-shaped clamping plates 9 to move towards each other and clamp the polymer materials on the rotating disc 8.

[0023] There are two sets of motors 7 in total. The output shaft of the motor 7 passes through the top end of the moving plate 6 through a bearing and is fixedly sleeved with a driving sprocket 13. Both the front and rear sides of the top end of the moving plate 6 are rotatably connected to a support shaft 14 through a bearing. The top end of the support shaft 14 is fixedly bolted to the bottom end of the turntable 8. A driven sprocket 15 is fixedly sleeved on the support shaft 14. A chain 16 is sleeved on both the driving sprocket 13 and the driven sprocket 15 and is connected by the chain 16 for transmission. By driving the driving sprocket 13 at the output end of the motor 7 to rotate, the driving sprocket 13 drives the driven sprocket 15 to rotate through the chain 16, thereby driving the support shaft 14 and the turntable 8 to rotate.

[0024] The traction drive mechanism includes a coil take-up machine 17 and a traction steel wire rope 18. Among them, there are two sets of coil take-up machines 17, which are fixedly bolted to the front and rear sides inside the machine table 1. The traction steel wire rope 18 is wound around the take-up wheel at the output end of the coil take-up machine 17. A traction plate 19 is fixedly bolted to the bottom end of the moving plate 6. The lower part of the traction plate 19 slides through to the inside of the machine table 1. A through groove adapted to the traction plate 19 is opened at the top end of the machine table 1. Traction rings 20 are fixedly welded to both the front and rear side walls of the traction plate 19. One end of the traction steel wire rope 18 away from the coil take-up machine 17 is fixedly connected to the traction ring 20. By respectively driving the traction steel wire ropes 18 on the take-up wheels at the output ends of the two sets of coil take-up machines 17 to wind or unwind, the traction ring 20 is pulled to drive the traction plate 19 to move, and then the traction plate 19 drives the moving plate 6 to move back and forth. Limit blocks 21 are fixedly bolted to both the left and right side walls of the traction plate 19. The top ends of the limit blocks 21 are slidably attached to the top end inside the machine table 1, playing a limiting role for the traction plate 19 to make its movement more stable. Support rollers 22 distributed at equal intervals are rotatably connected to both the left and right sides of the top end of the machine table 1, providing rolling support for the moving plate 6 to make its movement smoother.

[0025] A circular support ring 23 is provided below the turntable 8. The support ring 23 is fixedly bolted to the top end of the moving plate 6. Four groups of symmetrically distributed balls are fixed to the top end of the support ring 23, and the balls are in contact with the bottom end of the turntable 8, providing auxiliary support for the turntable 8.

[0026] The gear drive mechanism includes a second motor 24 and a rack 25. Among them, the second motor 24 is fixedly bolted to the rear outer wall of the drive box 3. The rack 25 is slidably connected to the bottom end inside the drive box 3. The output shaft of the second motor 24 passes through to the inside of the drive box 3 through a bearing and is fixed with a drive gear 26. The bottom end of the drive gear 26 meshes with the rack 25. A slider 27 is fixedly bolted to the center position of the bottom end of the rack 25. The bottom end of the slider 27 slides through the bottom end of the drive box 3 and is fixedly bolted to the top end of the air cylinder 4. A through groove adapted to the slider 27 is opened at the bottom end of the drive box 3. By driving the drive gear 26 at the output end of the second motor 24 to rotate, the drive gear 26 drives the engaged rack 25 to displace, and the rack 25 drives the air cylinder 4 to displace through the slider 27.

[0027] When it is necessary to perform glue spraying treatment on the surface of polymer materials during the preparation process of polymer materials, first place the two polymer materials to be glue-sprayed on two groups of turntables 8 at the top of the moving plate 6 respectively, and use the clamping mechanism to drive the two arc-shaped clamping plates 9 at the top of the turntable 8 to move towards each other until the polymer materials are clamped and fixed. Then start the traction drive mechanism to drive the moving plate 6 to move from front to back until the turntable 8 located at the front side moves below the drive box 3, so that the polymer material clamped at the top of the turntable 8 is under the glue spray gun 5. At this time, start the cylinder 4 to drive the glue spray gun 5 to descend and use the glue spray gun 5 to perform glue spraying on the surface of the polymer material. During the glue spraying process, start the motor 7 to drive the turntable 8 to rotate until the glue spray gun 5 sprays a circle of glue on the polymer material. When it is necessary to spray multiple circles of glue with different diameters, use the gear drive mechanism to drive the cylinder 4 to move horizontally to different positions at the bottom of the drive box 3, so that the glue spray gun 5 can spray multiple circles of glue on the polymer material;

[0028] After the current polymer material is finished with glue spraying, start the traction drive mechanism to drive the moving plate 6 to move from back to front until the turntable 8 located at the rear side moves below the drive box 3, so that the polymer material clamped at the top of the turntable 8 is under the glue spray gun 5 and continue the glue spraying treatment. While the rear polymer material is being glue-sprayed, remove the glue-sprayed polymer material located at the front side from the turntable 8 and reinstall the polymer material to be glue-sprayed. Repeat the above steps to make the two groups of turntables 8 take turns to move below the drive box 3 to achieve continuous glue spraying treatment of multiple groups of polymer materials.
