Description

Technical Field

[0001] This utility model relates to the technical field of cap tightening machines, specifically a cap tightening machine that can stably clamp caps. Background Technology

[0002] Capping machines, also known as screw capping machines, sealing machines, pressing machines, or locking machines, are widely used in automated equipment for tightening and loosening caps on plastic bottles, glass bottles, and other containers after they have been dispensed. They are mainly used in the food, pharmaceutical, daily chemical, pesticide, and cosmetic industries. In the process of pesticide production and processing, capping machines can be used to automatically tighten the caps between the filled pesticide bottles and the bottle body.

[0003] As disclosed in CN218058391U, a capping machine for pesticide production includes a base. The top of the base is fixedly equipped with the capping machine body. Support rods are symmetrically arranged on one side of the capping machine body. A fixed seat is fixedly connected to the bottom of the support rod. A trapezoidal block is fixedly arranged at the bottom of the fixed seat. The first elastic element, rotating rod, and handle rod make it easy to install and replace the cap. After the position of the connecting groove corresponds to the position of the positioning post, the cap moves upward. Then, by rotating the two handle rods outward, the handle rods squeeze the first elastic element. At the same time, the rotating rod also rotates. After the rotating rod rotates, it drives the locking block to rotate. After the position of the rotating rod after rotation corresponds to the position of the locking groove, the locking block fits against the inner wall of the locking groove with the rebound of the first elastic element, thereby fixing the position of the rotating rod and making it easy to replace the cap.

[0004] However, existing technologies have drawbacks such as inconvenience in cyclic conveying and batch capping of products, low efficiency in pesticide processing, and the tendency for excessive force to deform the bottle body when clamping it, or even cause pesticides to spill out of the bottle mouth. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a cap clamping machine with stable clamping capability. Utility Model Content

[0006] The purpose of this invention is to provide a capping machine that can stably clamp the bottle, so as to solve the problems mentioned in the background art, such as inconvenience in cyclic conveying and batch capping of products, low efficiency in pesticide processing, and easy deformation of the bottle body due to excessive force when clamping the bottle body, or even pesticide overflow from the bottle mouth.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cap clamping machine that can stably clamp, comprising a fixing frame, a conveying device, and a replaceable cap clamping cap;

[0008] Also includes:

[0009] The buffer clamping assembly is symmetrically arranged on the front and rear sides of the upper end of the fixed frame. It consists of a first electric telescopic rod for driving, a movable plate fixed to the output end of the first electric telescopic rod, a fixed clamping plate sleeved on the outside of the movable plate, an anti-slip rubber pad fixed on the inside of the fixed clamping plate, and a buffer spring disposed between the movable plate and the fixed clamping plate.

[0010] A movable plate is provided above the tight cap, and the movable plate drives the tight cap to rise and fall stably at the upper end of the conveying device. The inner side of the tight cap is provided with annular anti-slip teeth, which are composed of rubber strips arranged at equal angles on the inner side of the tight cap.

[0011] Preferably, auxiliary plates are fixedly connected to both the front and rear sides of the upper end of the fixed frame, and a first electric telescopic rod is installed in the middle of the auxiliary plates.

[0012] Preferably, the auxiliary plate is slidably connected to both the left and right ends, and the limiting rods are respectively fixedly connected to the left and right ends of the outer side of the movable plate;

[0014] Preferably, the limiting blocks are slidably connected to the left and right ends of the fixed clamping plate, and the inner side of the fixed clamping plate is telescopically connected to a movable plate.

[0015] Preferably, a connecting bracket is fixedly connected to the upper end of the auxiliary plate, and a second electric telescopic rod is fixedly installed on the top of the connecting bracket.

[0017] Preferably, the lower end of the mounting plate is engaged with a locking cap, and the locking cap and the mounting plate are limited by a fastening bolt that passes through the side of the mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the stable clamping capping machine can circulate and transport pesticide bottles through the conveying device, which facilitates batch capping of pesticide bottles and improves the processing efficiency of pesticides.

[0029] 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.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] To address the problems of inconvenient product circulation and batch capping in existing technologies, low efficiency in pesticide processing, and the risk of bottle deformation and pesticide spillage due to excessive force during bottle clamping, this solution provides a stable capping machine. The machine includes a fixed frame 1, a conveying device 2, and replaceable capping caps 16. Buffer clamping components are symmetrically arranged on the front and rear sides of the upper end of the fixed frame 1, driven by a first electric telescopic mechanism. The device consists of a rod 4, a movable plate 5 fixed to the output end of the first electric telescopic rod 4, a fixed clamping plate 8 sleeved on the outside of the movable plate 5, an anti-slip pad 9 fixed on the inside of the fixed clamping plate 8, and a buffer spring 10 set between the movable plate 5 and the fixed clamping plate 8. A movable plate 13 is set above the tight cap 16, and the movable plate 13 drives the tight cap 16 to rise and fall stably at the upper end of the conveying device 2. The inner side of the tight cap 16 is provided with annular anti-slip teeth, which are composed of rubber strips 17 set at equal angles on the inner side of the tight cap 16.

[0032] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, firstly, select a capping cap 16 corresponding to the pesticide bottle body and cap, slide and engage the capping cap 16 to the lower end of the mounting plate 15, and then limit the position between the capping cap 16 and the mounting plate 15 using the fastening bolts 18. Next, place the filled pesticide bottles on the conveying device 2 at certain intervals, with the bottle caps placed upright on the bottle mouths. The conveying device 2 circulates the pesticide bottles, facilitating batch capping of pesticide bottles. Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the pesticide bottle moves to the inside of the auxiliary plate 3, the controller activates the first electric telescopic rod 4 installed in the middle of the auxiliary plate 3. The first electric telescopic rod 4 pushes the movable plate 5 together with the fixed clamping plate 8 against the pesticide bottle body. At the same time, the inner side of the fixed clamping plate 8 is provided with an anti-slip pad 9, which contacts the bottle body. The movable plate 5 drives the limiting block 7 to slide between the fixed clamping plate 8 and the limiting rod 6 to slide between the auxiliary plate 3, improving stability during movement. The movable plate 5 compresses the buffer spring 10, causing the buffer spring 10 to undergo elastic deformation. The movable plate 5 extends and retracts within the fixed clamping plate 8, thus providing good buffer protection while ensuring stable clamping, preventing excessive clamping force on the bottle body from causing deformation or even pesticide spillage.

[0033] After clamping is completed, the second electric telescopic rod 12 installed on the top of the connecting bracket 11 is activated. The second electric telescopic rod 12 pushes the moving plate 13 to slide between the connecting bracket 11, thereby causing the cap 16 to move downward. The cap 16 is clamped down on the bottle cap, and the inner side of the cap 16 is provided with annular anti-slip teeth composed of rubber strips 17 at equal angles to increase the friction between it and the bottle cap. Then, the drive motor 14 is started to drive the mounting plate 15 to rotate at the lower end of the moving plate 13. The mounting plate 15 drives the cap 16 to rotate, thereby tightening the bottle cap. After tightening, the second electric telescopic rod 12 drives the moving plate 13 to move upward, causing the cap 16 to disengage from the bottle cap. Then, the clamping of the bottle is released, and the next bottle is transported through the conveying device 2. The above operation can be repeated.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
