Description

Technical Field

[0001] This utility model belongs to the technical field of quantitative valve production equipment, specifically relating to a quantitative valve production conveyor turntable. Background Technology

[0002] Metering valves are widely used in sprays, aerosols, and spray bottles. Their function is to pump compressed gas or liquid out of the can by pressing down on the valve stem. In order to achieve single-press single-dispense, a metering valve is installed at the connection point so that only a fixed amount of aerosol or liquid is dispensed with each press, thus achieving metered use.

[0003] To improve the production efficiency of metering valves, especially in the assembly stage, a rotating disc can be used to sequentially place, fix, and tighten the valve components during rotation, completing the production of metering valves in one cycle. This structure occupies little space and has high operating efficiency, effectively improving the production efficiency of metering valves. However, in current equipment production processes, to clamp the valve body, a single set of cylinders is often used to activate the clamping head to press and fix the valve body. But since the transfer holes on the rotating disc for placing the valve body include several sets, if each transfer hole requires a corresponding set of cylinders to open and close for fixation, then over time, the electricity consumed by the air compressor will become a considerable expense. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a production conveyor turntable for a quantitative valve. The valve body is placed in the clamping cavity formed between the rotating disc and the clamping disc. The rotating disc allows the clamping seat below it to be movably connected to the rotating seat. After the roller passes through the undulating lifting platform, the upward clamping and downward releasing operations are realized. This structure can fix the valve body without the intervention of a cylinder, saving energy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A production conveyor turntable for a metering valve includes a frame, a motor, a rotating assembly, and several valve bodies. The motor is located at the bottom of the frame. The rotating assembly includes a rotating disk, a rotating base, and a clamping disk. The rotating disk is connected to the rotating base. The output end of the motor passes through the frame and is connected to the rotating base. The edge of the rotating disk extends outward from the rotating base. Several conveying holes communicating with the outer wall of the rotating disk are evenly distributed on the edge of the rotating disk. The valve bodies are fitted into the conveying holes and do not contact the rotating base. The clamping disk is connected to the upper end of the rotating disk. The edge of the clamping disk and the edge of the rotating disk have a gap to form a clamping cavity. Several clamping holes communicating with the outer wall of the clamping disk are evenly distributed on the edge of the clamping disk. The axes of the clamping holes and the conveying holes coincide one by one.

[0007] It also includes a clamping assembly, which includes a clamping seat movably connected to a rotating seat, with clamping heads on the clamping seat corresponding to transfer holes; the clamping assembly also includes a slide and a slide rail, the slide being disposed on the clamping seat and the slide rail being disposed on the outer side wall of the rotating seat, the slide and the slide rail cooperating; the clamping assembly also includes a lifting platform, which is connected to the upper end face of the frame, the upper end face of the lifting platform having an upwardly protruding lifting portion, and rollers being disposed on the outer side wall of the clamping seat, the rollers abutting against the upper end face of the lifting platform.

[0008] The production conveyor turntable for this type of metering valve has a motor located at the bottom of the frame. The motor's output passes through the frame and drives a connected rotating base to rotate. A rotating disk fixed to the upper end of the rotating base also rotates with the base. Therefore, as the conveyor holes on the rotating disk pass sequentially through the feed inlet, insertion port, capping port, and clamping port during rotation, the valve body enters the conveyor hole and is assembled accordingly. To facilitate valve body entry, especially for metering valves, the valve body gradually extends vertically as the assembly progresses. Thus, the valve body fits snugly within the conveyor hole. The valve body must not contact the rotating seat during operation to avoid hindering the assembly of the metering valve. However, if the conveying hole is not connected to the outer wall of the rotating disc during final discharge, it will be difficult to discharge the material. To avoid this, the conveying hole is connected to the outer wall of the rotating disc, forming an outward-opening U-shaped structure. Therefore, when the valve body enters the conveying hole, its outer edge can effectively overlap the edge of the conveying hole, thus fixing the position of the valve body. During discharge, the valve body can be moved outward along the opening of the conveying hole to discharge the material, reducing the difficulty of discharge.

[0009] Because the outer edge of the valve body is lightweight and thin, it might easily detach upwards due to the rotation of the rotating disk if simply placed on the conveying hole. To avoid this, a clamping plate is added to the upper end of the rotating disk, with a gap between the edge of the clamping plate and the edge of the rotating disk to form a clamping cavity. This allows the valve body to be embedded in the clamping cavity at the beginning of feeding, achieving upper limit positioning. In this way, there is no need to worry about the valve body not being properly embedded in the conveying hole due to rotation or its own lightness and thinness. Moreover, the clamping hole on the clamping plate coincides with the axis of the conveying hole, so it will not be affected in the subsequent assembly of the valve body.

[0010] Although the valve body is embedded in the transfer hole, centrifugal force is inevitably generated during the rotation of the rotating disc. This centrifugal force causes the valve body to move towards the opening of the transfer hole. The moving valve body may detach from the axis of the clamping hole and the transfer hole, making subsequent assembly impossible. Therefore, a clamping assembly is added. The clamping head on the clamping seat abuts against the bottom of the valve body as the clamping seat moves upward along the direction of the slide block and slide rail, pressing it against the clamping disc to fix the valve body in place. In existing technology, the movement of the clamping seat is achieved by a cylinder, which leads to significant energy waste. Therefore, a [missing information - likely a cylinder or similar component] is added to the frame. The lifting platform is ring-shaped, with its upper surface exhibiting an undulating wave pattern. The upward-protruding structure is the lifting section, and rollers are added to the clamping seat, resting against the upper surface of the lifting platform. Therefore, during the rotation of the rotating seat, the clamping seat maintains its rollers in contact with the upper surface of the lifting platform under the influence of gravity. When the rollers pass through the lifting section, they cause the clamping seat to move upward, thereby lifting the valve body and placing it against the clamping plate. This structure uses a motor to drive the clamping seat to move up and down on the lifting platform, eliminating the need for a cylinder to push the clamping seat. Therefore, it can effectively save energy while maintaining smooth production.

[0011] Furthermore, the upper end face of the clamping hole is provided with an outwardly and upwardly extending guide portion.

[0012] Compared with the prior art, the advantages of this utility model are as follows: With the U-shaped conveying hole, the outer edge of the valve body can effectively overlap the edge of the conveying hole when it enters, thus fixing the valve body's position. During discharge, the valve body simply moves outward along the opening of the conveying hole, reducing the difficulty of discharge. The clamping cavity allows the valve body to be embedded in it at the beginning of feeding, achieving upper limit positioning. Simultaneously, the upward movement of the clamping head abuts against the lower part of the valve body, pressing it against the clamping plate, thereby fixing the valve body's position. The clamping seat is driven by a motor, causing it to move up and down on the lifting platform, eliminating the need for a cylinder to push it. Therefore, it effectively saves energy while maintaining smooth production. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

The motor 2 is located at the bottom of the frame 1. The rotating assembly 3 includes a rotating disk 31, a rotating seat 32, and a clamping disk 33. The rotating disk 31 is connected to the rotating seat 32. The output end of the motor 2 passes through the frame 1 and is connected to the rotating seat 32. The edge of the rotating disk 31 extends outward from the rotating seat 32. Several conveying holes 311 communicating with the outer wall of the rotating disk 31 are evenly distributed on the edge of the rotating disk 31. The valve bodies 4 are fitted into the conveying holes 311 and do not contact the rotating seat 32. The clamping disk 33 is connected to the upper end of the rotating disk 31. The edge of the clamping disk 33 and the edge of the rotating disk 31 are separated by a gap to form a clamping cavity 331. Several clamping holes 332 communicating with the outer wall of the clamping disk 33 are evenly distributed on the edge of the clamping disk 33. The axes of the clamping holes 332 and the conveying holes 311 coincide one by one.

[0023] It also includes a clamping assembly 5, which includes a clamping seat 51 movably connected to a rotating seat 32. The clamping head 52 on the clamping seat 51 corresponds to the transfer hole 311. The clamping assembly 5 also includes a slide 53 and a slide rail 54. The slide 53 is disposed on the clamping seat 51, and the slide rail 54 is disposed on the outer side wall of the rotating seat 32. The slide 53 and the slide rail 54 cooperate with each other. The clamping assembly 5 also includes a lifting platform 55, which is connected to the upper end surface of the frame 1. The upper end surface of the lifting platform 55 is provided with an upwardly protruding lifting part 551. The outer side wall of the clamping seat 51 is provided with a roller 511, which abuts against the upper end surface of the lifting platform 55.

[0024] Furthermore, the upper end face of the clamping hole 332 is provided with an outwardly and upwardly extending guide portion 333.

[0025] Description of the working principle of this utility model:

[0026] The production conveyor turntable for the metering valve using this structure has a motor 2 located at the bottom of the frame 1. The output end of the motor 2 passes through the frame 1 and drives the rotating seat 32 connected to it to rotate. The rotating disk 31 fixedly connected to the upper end of the rotating seat 32 also rotates with the rotating seat 32. Therefore, when the conveying hole 311 on the rotating disk 31 passes through the feed port, insertion port, capping port, and clamping port in sequence during rotation, the valve body 4 will enter the conveying hole 311 and be assembled accordingly. To facilitate the entry of the valve body 4, especially for metering valves, it will gradually extend vertically as the assembly process progresses. Therefore, the valve body 4 fits into the conveying hole 311. When the valve body 4 enters the conveying hole 311, it must not be in contact with the rotating seat 32 to avoid hindering the assembly of the metering valve. However, if the conveying hole 311 is not connected to the outer wall of the rotating disk 31 during final discharge, it will be difficult to discharge the material. To avoid this situation, the conveying hole 311 is connected to the outer wall of the rotating disk 31 to form a U-shaped structure with the opening facing outward. Therefore, when the valve body 4 enters the conveying hole 311, its outer edge can effectively overlap the edge of the conveying hole 311, thus fixing the position of the valve body 4. During discharge, the valve body 4 can be discharged by moving outward along the opening of the conveying hole 311, reducing the difficulty of discharge.

[0027] Because the outer edge of the valve body 4 is lightweight and thin, if it is simply placed on the conveying hole 311, it may detach upwards due to the rotation of the rotating disk 31. To avoid this, a clamping disk 33 is added to the upper end of the rotating disk 31, and the edge of the clamping disk 33 and the edge of the rotating disk 31 are left with a gap to form a clamping cavity 331. This allows the valve body 4 to be embedded in the clamping cavity 331 at the beginning of feeding, thus achieving upper limit. In this way, there is no need to worry about the valve body 4 not being properly embedded in the conveying hole 311 due to rotation or its own lightness and thinness. Moreover, the clamping hole 332 on the clamping disk 33 coincides with the axis of the conveying hole 311, so it will not be affected in the subsequent assembly of the valve body 4. In order to achieve the guiding role during assembly, an outward and upward extending guide part 333 is provided on the upper end face of the clamping hole 332, which can play a guiding role.

[0028] Although the valve body 4 is embedded in the transfer hole 311, centrifugal force is inevitably generated during the rotation of the rotating disk 31. This centrifugal force causes the valve body 4 to move towards the opening of the transfer hole 311. The moving valve body 4 will detach from the axis of the clamping hole 332 and the transfer hole 311, making subsequent assembly impossible. Therefore, a clamping assembly 5 is added. The clamping head 52 on the clamping seat 51 abuts against the lower part of the valve body 4 as the clamping seat 51 moves upward along the direction of the slide block 53 and the slide rail 54, pressing it against the clamping disk 33, thereby fixing the position of the valve body 4. In the prior art, the movement of the clamping seat 51 is achieved by a cylinder push, which leads to a large amount of energy waste. Therefore, a ring-shaped lifting mechanism is added to the frame 1. The upper surface of the lifting platform 55 is undulating, with the upward-protruding structure being the lifting part 551. Rollers 511 are added to the clamping seat 51, which abuts against the upper surface of the lifting platform 55. Therefore, during the rotation of the rotating seat 32, the clamping seat 51, under its own weight, keeps its rollers 511 abutting against the upper surface of the lifting platform 55. When the rollers 511 pass the lifting part 551, they cause the clamping seat 51 to move upward, thereby lifting the clamping head 52 and placing it against the clamping plate 33. This structure allows the clamping seat 51 to move up and down on the lifting platform 55 via the drive of the motor 2, eliminating the need for a cylinder to push the clamping seat 51. Therefore, it effectively saves energy while maintaining smooth production.

[0029] The beneficial effects of this utility model are as follows: With the U-shaped conveying hole 311, when the valve body 4 enters the conveying hole 311, its outer edge can effectively overlap the edge of the conveying hole 311, thus fixing the position of the valve body 4. During discharge, the valve body 4 can be discharged by moving outward along the opening of the conveying hole 311, reducing the difficulty of discharge. The clamping cavity 331 allows the valve body 4 to be embedded in the clamping cavity 331 at the beginning of feeding, thus limiting its upper end. At the same time, with the upward movement of the clamping head 52, it abuts against the lower part of the valve body 4, pressing it against the clamping plate 33, thereby fixing the position of the valve body 4. The clamping seat 51 is driven by the motor 2, which makes the clamping seat 51 move up and down on the lifting platform 55. There is no need to connect a cylinder to push the clamping seat 51, so energy can be effectively saved while maintaining smooth production.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
