Pesticide filling and capping mechanism

Abstract

This utility model belongs to the technical field of capping equipment, specifically a pesticide filling and capping mechanism, including a machine body. The machine body includes a feeding conveyor, a rotating support, and a discharging conveyor arranged sequentially. A rotating turntable is mounted on the rotating support via a rotary motor. The rotating support also has a capping mechanism, a pressing mechanism, and a screwing mechanism distributed along the circumference of the turntable. In this utility model, two clamping blocks are set on the clamping seat. The rotary motor drives a drive gear plate to rotate, which in turn rotates and switches the clamping blocks to automatically clamp the moved pesticide bottle. Simultaneously, it moves the pesticide bottle below the pressing mechanism to directly below the screwing mechanism. During this process, the drive gear plate meshes with the first pulley and rotates 180°, allowing the clamping blocks to precisely clamp the pesticide bottle for screwing. This design eliminates the need for the separate extension and retraction of traditional cylinders, reducing costs and automating the clamping and releasing of pesticide bottles at the screwing station.

Description

Technical Field

[0001] This utility model belongs to the technical field of capping equipment, and in particular relates to a pesticide filling and capping mechanism. Background Technology

[0002] Pesticide filling and capping refers to the process of accurately measuring and injecting prepared liquid pesticides into specific packaging containers (such as plastic bottles, glass bottles, metal cans, etc.) through filling equipment, and then immediately sealing the container opening tightly.

[0003] The specific steps are as follows: pesticide bottles are transported by a conveyor line, then the caps are transported to the bottle mouth, and the caps are pressed and tightened in sequence. During the tightening step, it is necessary to ensure the stability of the bottle and prevent the bottle from rotating during the tightening process.

[0004] Traditional methods mostly use cylinders and clamps, but the clamps can only be pressed against the bottle by the cylinder after the bottle has rotated to the correct position each time; after the cap is screwed on, the clamps need to be returned to their original position before the bottle can be moved, which affects the efficiency of mass production.

[0005] To address the aforementioned issues, this application proposes a pesticide filling and capping mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a pesticide filling and capping mechanism that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a pesticide filling and capping mechanism, comprising a machine body, which includes a feeding conveyor, a rotating support, and a discharging conveyor arranged sequentially. A rotating turntable is mounted on the rotating support via a rotary motor. The rotating support also includes a capping mechanism, a pressing mechanism, and a screwing mechanism distributed circumferentially along the turntable. A horizontal clamp is rotatably connected to the side of the rotating support via a support frame. The clamp has circumferentially distributed support rods around its outer ring, with clamping blocks fixed to the front ends of the support rods. Power is transmitted between the output end of the rotary motor and the clamp via a transmission mechanism. The turntable rotates in the opposite direction to the clamp. When the rotary motor moves the pesticide bottle on the turntable once, the circumferentially arranged clamping blocks also rotate once under the action of the transmission mechanism. After each rotation to its final position, the clamping blocks clamp the pesticide bottle below the screwing mechanism.

[0009] Furthermore, there are two clamping blocks. When the rotary motor drives the pesticide bottle on the turntable to move once, the two clamping blocks rotate 180° and clamp the pesticide bottle.

[0010] Furthermore, the support frame is fixed on the rotating bracket and has a bushing formed thereon, and a long shaft is fixed at the lower end of the clamp and rotatably connected to the bushing.

[0011] Furthermore, the transmission mechanism includes a drive gear fixed to the output end of the rotary motor and a driven gear rotatably disposed at one end of the support frame, wherein the driven gear meshes with the drive gear.

[0012] Furthermore, a first pulley is fixed to the bottom of the driven gear, and a second pulley is fixed to the bottom of the long shaft. The first pulley and the long shaft are synchronously connected by a timing belt.

[0013] Furthermore, the output end of the rotary motor is fixed with a connecting seat that is rotatably connected to the rotary bracket. The turntable is fixedly installed with the connecting seat. A baffle is provided on the upper end of the rotary bracket near the cover mechanism, the pressing mechanism, and the screwing mechanism. A through groove for rotating the clamping block is opened on the baffle and it is located below the screwing mechanism.

[0014] Furthermore, the front end of the clamping block is arc-shaped and equipped with a rubber pad.

[0015] This utility model has the following beneficial effects:

[0016] This utility model sets two clamping blocks on the clamping base, and then, driven by the transmission component, the two clamping blocks rotate and switch to correspond with the adjacent pesticide bottles. In this way, when the pesticide bottles are capped, they can be automatically clamped by the driving force of the rotary motor, eliminating the need for the separate extension and retraction action of the traditional cylinder, and reducing costs compared to the cylinder.

[0017] After the active toothed disc rotates and moves the pesticide bottle below the capping mechanism to below the screw-on mechanism, the active toothed disc engages and drives the first pulley to rotate 180°. In this state, the pesticide bottle is clamped by the clamping block directly below the screw-on mechanism. Through precise transmission and coordination, the clamping and loosening of the pesticide bottle below the screw-on mechanism is automated.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1 - Figure 5As shown, this utility model is a pesticide filling and capping mechanism, including a body 1. The body 1 includes a feeding conveyor 11, a rotating support 12, and a discharging conveyor 13 arranged sequentially. The feeding conveyor 11 and the discharging conveyor 13 have the same structure and are equipped with a conveyor belt and baffles for guiding the movement path of the pesticide bottles. The feeding conveyor 11 is connected to the discharge end of the filling equipment and is used to transport the filled pesticide bottles to the capping mechanism. The rotating support 12 is equipped with a rotating turntable 121 via a rotating motor 122. The turntable 121 has several U-shaped grooves evenly spaced along its circumference for the entry and exit of pesticide bottles. Figure 1 The turntable 121 shown is driven by the rotary motor 122 and rotates clockwise. The rotating support 12 is also provided with a top cover mechanism 14, a capping mechanism 15, and a screw cap mechanism 16 distributed along the circumference of the turntable 121 in a clockwise direction. When the rotary motor 122 drives the turntable 121 to rotate, the pesticide bottle under the top cover mechanism 14 moves to the bottom of the capping mechanism 15, and the pesticide bottle under the capping mechanism 15 moves to the bottom of the screw cap mechanism 16, thus forming a multi-process switching.

[0030] In use, the capping mechanism 14 is connected to a feeding machine for conveying the caps and finally placing them onto the pesticide bottle; the capping mechanism 15 is equipped with a cylinder, and the bottom of the cylinder is equipped with a pressure block for initially positioning the caps on the pesticide bottle; the screwing mechanism 16 is equipped with a cylinder, a buffer, a motor, and a screwing sleeve from top to bottom. When screwing, the cylinder pushes down, the screwing sleeve contacts the cap, the buffer is compressed, the motor rotates, and the cap and pesticide bottle are screwed together. During the screwing process, the cap will move down, and the buffer pushes the screwing sleeve to always contact the cap through the internal spring, thereby achieving the purpose of sealing.

[0031] Specifically, the side of the rotating bracket 12 is rotatably connected to a horizontal clamp 2 via a support frame 3. The outer ring of the clamp 2 is provided with circumferentially distributed support rods 21. The front end of the support rods 21 is fixed with a clamping block 22. The output end of the rotating motor 122 and the clamp 2 are connected by a transmission mechanism to transmit power. The rotation direction of the turntable 121 is opposite to that of the clamp 2. When the rotating motor 122 drives the pesticide bottle on the turntable 121 to move once, the circumferentially arranged clamping block 22 also rotates once under the action of the transmission mechanism. After each rotation to the position, the clamping block 22 clamps the pesticide bottle below the capping mechanism 16.

[0032] Furthermore, there are two clamping blocks 22. When the rotary motor 122 drives the pesticide bottle on the turntable 121 to move once, the two clamping blocks 22 rotate 180° and clamp the pesticide bottle. In this embodiment, by linking the power of the rotary motor 122 with the rotation of the clamping blocks 22, the automatic clamping of the pesticide bottle below the capping mechanism 16 is realized, thereby improving the capping efficiency.

[0033] Specifically, in order to ensure that the clamp 2 rotates stably on the support frame 3, the support frame 3 is fixed to the rotating bracket 12 by bolts and has a bushing 31 formed thereon. The lower end of the clamp 2 is fixed with a long shaft 23 which is rotatably connected to the bushing 31.

[0034] Specifically, the transmission mechanism includes a drive gear 1221 fixed to the output end of the rotary motor 122 and a driven gear 4 rotatably disposed at one end of the support frame 3. The driven gear 4 meshes with the drive gear 1221. A first pulley 41 is fixed to the bottom of the driven gear 4, and a second pulley 24 is fixed to the bottom of the long shaft 23. The first pulley 41 and the long shaft 23 are synchronously connected by a synchronous belt 5.

[0035] Specifically, the output end of the rotary motor 122 is fixed with a connecting seat 123 that is rotatably connected to the rotary bracket 12. The turntable 121 is fixedly installed with the connecting seat 123. A baffle 124 is provided on the upper end of the rotary bracket 12 near the cover mechanism 14, the cover pressing mechanism 15, and the cover tightening mechanism 16. The baffle 124 has a through groove for the rotation of the clamping block 22 and is located below the cover tightening mechanism 16.

[0036] To further ensure the stable clamping of the pesticide bottle by the clamping block 22, the front end of the clamping block 22 is arc-shaped and is provided with a rubber pad 221.

[0037] Understandably, this invention features two clamping blocks on the clamping base. A rotary motor drives a drive gear plate to rotate, which in turn rotates and switches the clamping blocks to automatically clamp the pesticide bottle that has been moved into position. Simultaneously, it moves the pesticide bottle below the capping mechanism to directly below the screw-on mechanism. During this process, the drive gear plate engages with the first pulley and rotates 180°, allowing the clamping blocks to precisely clamp the pesticide bottle for screw-on capping. This design eliminates the need for the separate extension and retraction of traditional cylinders, reducing costs and automating the clamping and releasing of pesticide bottles at the screw-on capping station.

[0038] One specific application of this embodiment is as follows: Figure 1-2 As shown, the pesticide bottle below the capping mechanism 16 is in a clamped state. At this time, one clamping block 22 on the clamping seat 2 contacts the outer wall of the pesticide bottle, and the rubber pad 221 ensures the clamping force and prevents rotation. The capping mechanism 16 performs the capping operation. After tightening, the rotary motor 122 drives the turntable 121 to rotate, which in turn drives the active gear plate 1221 to rotate synchronously. After the active gear plate 1221 rotates, it meshes with the driven gear 4 and drives the first pulley 41 to rotate. The first pulley 41 drives the second pulley 24 to rotate through the synchronous belt 5. After the second pulley 24 rotates, it drives the upper long shaft 23 to rotate in the bushing 31, and at the same time drives the upper clamping seat 2, support rod 21, and clamping block 22 to rotate. When the pesticide bottle below the capping mechanism 15 moves to directly below the capping mechanism 16 under the action of the rotation of the turntable 121, the other clamping block 22 on the clamping seat 2 clamps the pesticide bottle.
