Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic production technology, and in particular to a plastic product inner film spraying device. Background Technology
[0002] Plastic products are made of plastic, a high molecular weight compound polymerized through addition or condensation polymerization. Commonly known as plastic or resin, its composition and shape can be freely changed. It consists of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Bottled plastic products are coated with water-based paint on their inner walls after production.
[0003] In the process of spraying paint onto plastic bottles, a nozzle is inserted into the bottle for spraying. During this process, a cylinder controls the nozzle's insertion into the bottle. In existing technology, workers must manually control the cylinder's opening and closing, thus increasing the difficulty of the work. Furthermore, in existing technology, workers must remove a finished bottle before inserting a new one for spraying, thereby reducing work efficiency. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides an inner film spraying device for plastic products.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic product inner film spraying device, including a base plate, a rotating seat with an open top fixedly disposed on the upper surface of the base plate, a rotating platform rotatably disposed inside the rotating seat, a plurality of receiving grooves arranged in a circumferential array on the rotating platform, a support frame with an L-shaped cross-section fixedly disposed on the upper surface of the base plate, a cylinder fixedly disposed on the upper surface of the support frame, a spraying component fixedly disposed at the end of the piston rod of the cylinder, and a control component for controlling the rotation of the rotating platform disposed inside the rotating seat.
[0006] By adopting the above technical solution, when workers need to spray the inner wall of plastic products, they must place the plastic product into the receiving tank. Then, the worker activates the cylinder, causing the piston rod to extend, thus moving the spraying part downwards under the action of the piston rod, allowing it to penetrate the plastic product and spray it. After spraying is complete, the worker closes the cylinder, causing the piston rod to retract, and the spraying part to move upwards. Subsequently, the worker controls the rotating table to rotate, moving the next receiving tank below the cylinder. During this process, the worker only needs to rotate the rotating table to spray new plastic products without having to remove and place them again, thereby improving work efficiency.
[0007] Furthermore, the control component includes a connecting rod fixedly mounted on the bottom surface of the rotary table, a rotating disk fixedly mounted on the bottom surface of the connecting rod, a motor fixedly mounted on the inner bottom wall of the rotating seat, a drive disk fixedly mounted on the end of the motor output shaft, and a drive rod fixedly mounted on the upper surface of the drive disk. The upper surface of the rotating disk has a plurality of drive grooves arranged in a circumferential array. The drive rod matches the drive grooves. The upper surface of the drive disk abuts against the bottom surface of the rotating disk.
[0008] By adopting the above technical solution, when the operator needs to rotate the rotary table, the operator needs to start the motor, which in turn rotates the motor output shaft. This causes the drive disc to rotate under the action of the motor output shaft, which in turn causes the drive rod to rotate under the action of the drive disc, which in turn causes the rotary table to rotate under the action of the drive rod, which in turn causes the connecting rod to rotate under the action of the rotary table, and finally causes the rotary table to rotate under the action of the connecting rod. During this process, [the following text appears to be incomplete and requires further context: "by..."] Figure 3 Thus, the drive disc can rotate 360 degrees and the rotating disc can rotate 90 degrees, thereby moving the next receiving slot to below the cylinder, thereby improving the work efficiency of the staff.
[0009] Furthermore, a limiting disk is fixedly provided on the upper surface of the drive disk, and multiple limiting grooves are arrayed on the outer wall of the rotating disk. The limiting disk and the limiting grooves are matched with each other, and an avoidance groove is provided on the limiting disk.
[0010] By adopting the above technical solution, when the drive disc rotates, the limiting disc rotates along with it, causing the limiting disc and the limiting groove to rotate relative to each other. During this process, the limiting disc limits the rotation of the drive disc, thereby reducing the probability of the drive disc rotating during use and improving the stability of the device. Furthermore, the clearance groove avoids the drive disc, further reducing the probability of the clearance groove colliding with the limiting disc during rotation, thus improving the stability of the device.
[0011] Furthermore, an annular groove is provided on the inner wall of the rotating seat, and an annular block is rotatably disposed in the annular groove, the annular block being fixed to the rotating table.
[0012] By adopting the above technical solution, when the rotary table rotates, the ring block rotates under the action of the rotary table. During this process, the ring block limits the rotary table, thereby reducing the probability of the rotary table falling downwards under the action of gravity, thus improving the stability of the device.
[0013] Furthermore, the cylinder is equipped with a rear limit switch and a front limit switch, and the upper surface of the rotary table is circumferentially arrayed with multiple infrared detectors. The cylinder piston rod is equipped with an infrared detector, and the infrared detectors are used to be detected by the infrared detectors.
[0014] Furthermore, a time relay and an intermediate relay are provided on the support frame.
[0015] Furthermore, a counter is provided on the output shaft of the motor.
[0016] By adopting the above technical solution, after the motor output shaft rotates 360 degrees, the counter controls the motor to stop rotating. At this time, the next receiving slot moves to below the cylinder, and then the infrared detector detects the infrared detection element, such as... Figure 5 As shown, when the infrared detector detects the infrared sensor, its normally open contact closes. Since the cylinder is in the closed state, the normally open contact of the cylinder's rear limit switch closes, which in turn energizes the controller coil, causing the controller's normally open contact to close and thus locking the controller. Once the controller's normally open contact closes, the controller starts the cylinder, moving it to the front limit switch, which then closes, energizing the time relay coil and starting the timer (the timing period is the time required for spraying the part). When the timing is complete, the normally closed contact of the time relay opens, de-energizing the controller and resetting its contacts, thus closing the cylinder. The operator can then restart the motor for the next spraying cycle. This process eliminates the need for manual cylinder operation, reducing the workload for the operator.
[0017] Furthermore, a control button is provided on the base plate, and the control button is electrically connected to the motor.
[0018] By adopting the above technical solution, the control button reduces the difficulty for staff to start the motor, thereby reducing the workload of the staff.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, when a worker needs to spray paint the inner wall of a plastic product, the worker must place the plastic product into a receiving tank. Then, the worker activates a cylinder, causing the cylinder piston rod to extend, thus moving the spraying part downwards under the action of the piston rod, allowing it to penetrate the plastic product and spray it. After spraying is complete, the worker closes the cylinder, causing the piston rod to retract, thus moving the spraying part upwards. Subsequently, the worker controls the rotary table to rotate via a control component, moving the next receiving tank below the cylinder. During this process, the worker only needs to rotate the rotary table to spray new plastic products without needing to remove and place them again, thereby improving the worker's work efficiency.
[0021] 2. In this application, when the operator needs to rotate the rotary table, the operator needs to start the motor, which in turn causes the motor output shaft to rotate. This causes the drive disc to rotate under the action of the motor output shaft, which in turn causes the drive rod to rotate under the action of the drive disc, which in turn causes the rotary table to rotate under the action of the drive rod, which in turn causes the connecting rod to rotate under the action of the rotary table, thus causing the rotary table to rotate under the action of the connecting rod. During this process, [the following text is incomplete and likely refers to a different process:] Figure 3 Thus, the drive disc can rotate 360 degrees and the rotating disc can rotate 90 degrees, thereby moving the next receiving slot to below the cylinder, thereby improving the work efficiency of the workers.
[0022] 3. In this application, when the drive disc rotates, the limiting disc rotates along with it, causing the limiting disc and the limiting groove to rotate relative to each other. During this process, the limiting disc limits the rotation of the drive disc, thereby reducing the probability of the drive disc rotating during use and improving the stability of the device. Furthermore, the clearance groove avoids the drive disc, reducing the probability of the rotation groove colliding with the limiting disc during rotation and further improving the stability of the device.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-5 As shown in the figure, this application discloses an inner film spraying device for plastic products, including a base plate 1, a rotating seat 11, a rotating table 12, a support frame 14, a cylinder 15, a control component 2, a limiting plate 3, an annular block 41, an infrared detector 5, and a counter 6. The base plate 1 is a rectangular plate structure, and the rotating seat 11 is a cylindrical structure with an open top and a vertical axis. The rotating seat 11 is fixedly mounted on the upper surface of the base plate 1. The rotating table 12 is a cylindrical structure with its axis coinciding with the axis of the rotating seat 11. The rotating table 12 is rotatably mounted inside the rotating seat 11, and multiple receiving slots 13 are arranged in a circular array on the rotating table 12. The support frame 14 has an L-shaped cross-section and is fixedly mounted on the upper surface of the base plate 1. The cylinder 15 is fixedly mounted on the upper surface of the support frame 14, and its piston rod axis is vertical. The spraying part (not shown in the figure) is fixedly mounted at the end of the piston rod of the cylinder 15 and is used to spray the interior of the plastic product.
[0031] When workers need to spray paint the inner wall of a plastic product, they first place the product into the receiving slot 13. Then, the worker activates cylinder 15, extending its piston rod. This causes the spraying part to move downwards under the action of the piston rod, penetrating the plastic product to spray it. After spraying, the worker closes cylinder 15, retracting the piston rod and moving the spraying part upwards. Then, the worker controls the rotary table 12 to rotate via control component 2, moving the next receiving slot 13 below cylinder 15. During this process, the worker only needs to rotate the rotary table 12 to spray new plastic products without needing to remove and reinsert them, thus improving work efficiency.
[0032] Control component 2 is disposed within rotary base 11 and is used to control the rotation of rotary table 12. Control component 2 includes connecting rod 21, rotating disk 22, motor 23, drive disk 24, and drive rod 25. Connecting rod 21 is a cylindrical rod structure, its axis coinciding with the axis of rotary table 12, and is fixedly disposed on the bottom surface of rotary table 12. Rotating disk 22 is fixedly disposed on the bottom surface of connecting rod 21, and its upper surface has a circumferential array of drive grooves 26. Motor 23 is fixedly disposed on the inner bottom wall of rotary base 11, and its piston rod axis is vertical. Drive disk 24 is fixedly disposed at the end of motor 23's output shaft, its axis coinciding with the axis of motor 23's output shaft, and its upper surface abuts against the bottom surface of rotating disk 22. Drive rod 25 is a cylindrical rod structure with a vertical axis, and is fixedly disposed on the upper surface of drive disk 24, with drive rod 25 matching the drive grooves 26.
[0033] When the operator needs to rotate the rotary table 12, the operator needs to start the motor 23, which in turn rotates the output shaft of the motor 23. This causes the drive disk 24 to rotate under the action of the motor 23 output shaft, which in turn causes the drive rod 25 to rotate under the action of the drive disk 24. This causes the rotary table 22 to rotate under the action of the drive rod 25, which in turn causes the connecting rod 21 to rotate under the action of the rotary table 22, thus causing the rotary table 12 to rotate under the action of the connecting rod 21. During this process, the rotary table 12 is rotated by the drive rod 25. Figure 3 Thus, the drive disc 24 can rotate 360 degrees and the rotating disc 22 can rotate 90 degrees, thereby moving the next receiving slot 13 to below the cylinder 15, thereby improving the work efficiency of the staff.
[0034] The limiting plate 3 is a circular plate structure, and its axis coincides with the axis of the driving plate 24. Multiple limiting grooves 31 are arrayed on the outer wall of the rotating plate 22. The limiting plate 3 and the limiting grooves 31 match each other, and the limiting plate 3 is provided with a clearance groove 32.
[0035] When the drive disk 24 rotates, the limiting disk 3 rotates along with it, causing the limiting disk 3 to rotate relative to the limiting groove 31. During this process, the limiting disk 3 limits the rotation of the rotating disk 22, thereby reducing the probability of the rotating disk 22 rotating during use and improving the stability of the device. Furthermore, the clearance groove 32 avoids the rotating disk 22, further reducing the probability of the rotating groove colliding with the limiting disk 3 during rotation, thus improving the stability of the device.
[0036] An annular groove 4 is provided on the inner wall of the rotating seat 11. An annular block 41 is rotatably disposed in the annular groove 4, and its axis coincides with the axis of the rotating table 12. The annular block 41 and the rotating table 12 are fixed to each other.
[0037] When the rotating platform 12 rotates, the annular block 41 rotates under the action of the rotating platform 12. During this process, the annular block 41 limits the rotating platform 12, thereby reducing the probability of the rotating platform 12 falling downward under the action of gravity, thus improving the stability of the device.
[0038] A rear limit switch (not shown in the figure) is mounted on cylinder 15, and a front limit switch (not shown in the figure) is mounted on cylinder 15. Multiple infrared detectors 5 are arranged in a circumferential array on the upper surface of the rotary table 12. An infrared detector (not shown in the figure) is mounted on the piston rod of cylinder 15. The infrared detectors 5 are used to be detected by the infrared detector.
[0039] A time relay (not shown in the figure) is mounted on the support frame 14, an intermediate relay (not shown in the figure) is mounted on the support frame 14, and a counter 6 is mounted on the output shaft of the motor 23.
[0040] After the output shaft of motor 23 rotates 360 degrees, counter 6 controls motor 23 to stop rotating. At this time, the next receiving slot 13 moves to below cylinder 15, and then the infrared detector detects the infrared detection element 5, such as... Figure 5 As shown, when the infrared detector detects the infrared detection element 5, the normally open contact of the infrared detector closes. Since cylinder 15 is in the closed state, the normally open contact of the rear limit switch of cylinder 15 closes, which in turn energizes the controller coil, causing the normally open contact of the controller to close, thus locking the controller. When the normally open contact of the controller closes, the controller controls cylinder 15 to start, causing cylinder 15 to move to the front limit switch, which in turn closes the front limit switch of cylinder 15, energizing the time relay coil and starting the timer (the timing period is the time required for spraying the part). When the timing is complete, the normally closed contact of the time relay opens, de-energizing the controller, resetting the controller contacts, and closing cylinder 15. Subsequently, the operator can restart motor 23 to perform the next spraying. During this process, the operator does not need to manually start cylinder 15, thus reducing the difficulty of the operator's work.
[0041] To reduce the difficulty of the work for the staff, a control button 7 is installed on the base plate 1, and the control button 7 is electrically connected to the motor 23. The control button 7 reduces the difficulty for the staff to start the motor 23, thereby reducing the difficulty of the work for the staff.
[0042] The operating principle of the plastic product inner film spraying device in this embodiment is as follows: When a worker needs to spray the inner wall of a plastic product, the worker places the plastic product into the receiving groove 13. Then, the worker activates the cylinder 15, causing the piston rod of the cylinder 15 to extend, thus moving the spraying part downwards under the action of the piston rod, allowing the spraying part to penetrate into the plastic product and spray it. After spraying is completed, the worker closes the cylinder 15, causing the piston rod to retract, thus moving the spraying part upwards. Subsequently, the worker controls the rotating table 12 to rotate via the control component 2, thereby moving the next receiving groove 13 below the cylinder 15. During this process, the worker only needs to rotate the rotating table 12 to spray new plastic products without having to remove and place them again, thus improving the worker's work efficiency.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
