Description

Technical Field

[0001] The utility model relates to the technical field of beverage production, in particular to an automatic correction and capping machine. Background Art

[0002] In the production process of liquid-filled beverages, tightening the caps on plastic bottles presents technical challenges in precisely aligning the bottle and cap, and ensuring a tight rotational fastening. This step requires extremely high precision, and currently used packaging lines have limitations in achieving this alignment. Capping equipment typically operates using a uniform air pressure standard when producing the same beverage. If crooked caps reaching the capping mechanism are also tightened, this can cause the caps in the finished product to skew, leaking liquid, or even cracking and damaging. This leads to significant cap loss, increased manual inspection and screening time, and significantly increased production costs. Furthermore, products that are not promptly removed due to skewed or damaged caps are prone to leakage during subsequent storage or transportation, further exacerbating resource waste. Therefore, there is an urgent need for a more efficient, precise, and automated cap tightening device to address the bottlenecks and challenges in the current production process.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope and application of the present invention.

[0023] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically specified.

[0024] like Figure 1As shown, an automatic correction capping machine includes a bottle body conveying mechanism 1, a bottle cap conveying mechanism 2, a capping mechanism 3, a first pressing piece 204 and a soft hammer 4; the bottle body conveying mechanism 1 is arranged horizontally; the bottle cap transmission mechanism 2 includes a first conveyor belt, which is arranged obliquely just above the bottle body conveying mechanism, and its inclination angle is 15° to 30°, so that the bottle caps are conveyed obliquely from a high place to a low place; a first mounting plate 202 is arranged near the bottom end of the first conveyor belt, and the plate used to make the first mounting plate 202 has a certain thickness. It will not be easily deformed during use. It spans above the first conveyor belt and is in the shape of a flat arch. A plurality of first through holes are provided on its top. A long first connecting member 203 is provided through the first through holes. The bottom of the first connecting member 203 is welded to the first pressing plate 204. The first pressing plate 204 is in the shape of a long thin sheet and is tilted along the conveying direction of the first conveyor belt in the first mounting plate 202. The tilt angle is 1° to 2° larger than the tilt angle of the first conveyor belt. The end of the first pressing plate 204 protrudes from the bottom end of the first conveyor belt ( Figure 1 The first pressing plate 204 protrudes from the bottom of the first conveyor belt by about the diameter of the bottle cap, which makes the bottle caps near the bottom of the first conveyor belt receive slightly greater pressure. The first pressing plate 204 protruding from the first conveyor belt can just apply pressure to the bottle caps so that the bottle caps can be better covered on the bottle mouth. A soft hammer 4 is vertically arranged near the end of the first pressing plate 204. The soft hammer 4 is a certain distance away from the bottle mouth on the bottle body. A driving mechanism 5 is used to connect the soft hammer 4 so that the soft hammer 4 can move up and down instantaneously in the vertical direction. When the soft hammer 4 moves downward to the lowest position, it can apply instantaneous force to the bottle cap, so that the bottle cap is pressed down a certain distance, achieving the effect of correcting the position of the bottle cap. In this example, the length of the first pressing plate 204 is six times the diameter of the bottle cap, which means that it only needs to press down five bottle caps on the first conveyor belt. This prevents the bottle caps from inevitably tilting up during the production process, which affects the production efficiency of the assembly line and even causes the bottle caps to be skewed when covered on the bottle mouth.

[0025] In some examples of this embodiment, the first connecting member 203 is a bolt, so that the bolt is loosely fitted with the first through hole, and a plurality of nuts are provided on the bolt, at least one of which is provided above the top of the first mounting plate, so that the first pressing plate 204 can move up and down. In order to enable the first pressing plate 204 to better press the bottle caps conveyed by the first conveyor belt, a first spring 205 can be provided above the first pressing plate 204 and near the end of the first pressing plate 204 in a contact manner, such as Figure 1 As shown, in this embodiment, a first spring 205 is provided at the position where the first pressing piece 204 is about to protrude from the first conveyor belt. Both ends of the first spring 205 span the first pressing piece 204, which can reset the first pressing piece 204 that is tilted by the bottle cap.

[0026] In some other examples of this embodiment, the width of the first pressing plate 204 is greater than two-thirds of the diameter of the bottle cap, and the center line of the first pressing plate 204 in the width direction coincides with the center line of the first conveyor belt, so that the force applied by the first pressing plate 204 on the bottle cap is balanced, which can avoid the deviation of the bottle cap coming out of the first conveyor belt to a certain extent.

[0027] In some other examples of this embodiment, a second pressing plate 211 is further included. The second pressing plate 211 is in a bent shape, which is similar to the shape of the mirror image of "Z". A second through hole is provided at the upper end thereof, and a second strip-shaped second connecting member 212 is provided through the second through hole. A second spring 213 is provided above the second pressing plate 211 around the second connecting member 212. The bottom of the second connecting member 212 is welded to the first mounting plate 202, and the second connecting member 212 is loosely matched with the second through hole. The plane of the lower end of the second pressing plate 211 is on the first In the extension direction of the pressing piece 204, and in the vertical direction, it partially overlaps with the position of the first pressing piece 204. That is to say, when the second pressing piece 211 moves downward, the lower end of the second pressing piece 211 will hit the end of the first pressing piece 204. Due to the clearance fit, the second pressing piece 211 is lifted up by the bottle cap as a whole. Due to the action of the second spring 213, a downward force is applied to the second pressing piece 211, which can effectively prevent the bottle cap from being bounced up at the moment it leaves the first pressing piece 204, and prevent the bottle cap from being skewed and mismatched with the bottle mouth.

[0028] In some other examples of this embodiment, a clamping claw is further included, which includes two symmetrically arranged claw pieces 206, a third through hole is vertically provided at the right end of the claw piece 206, and a third connecting member 207 is provided in the third through hole. The two claw pieces 206 are symmetrically arranged on both sides of the first conveyor belt through the third connecting member 207, and the claw piece 206 can rotate around the third connecting member 207. The side of the claw piece 206 close to the first conveyor belt is set into an arc surface bent toward the first conveyor belt, the diameter of the arc surface is larger than the diameter of the bottle cap, and the distance between the leftmost ends of the two claw pieces 206 is smaller than the diameter of the bottle cap. A fourth through hole is vertically provided at the position, and a fourth connecting piece 208 is provided in the fourth through hole. Both ends of the first spring 205 are connected to the fourth connecting piece 208. The claw piece 206 partially extends out of the first conveyor belt, and the extended distance is consistent with the distance that the first pressing piece 204 protrudes from the first conveyor belt. When the bottle cap leaves the end of the first conveyor belt, the two claw pieces 206 cooperate to give the bottle cap an inward force, similar to grabbing the bottle cap, so that the bottle cap can be covered on the bottle mouth more smoothly. After the bottle cap is covered, the bottle body continues to move to the left, during which the two claw pieces 206 continue to open and reset, and the first spring 205 plays the role of resetting the claw piece.

[0029] In some other examples of this embodiment, an adjustment member 209 is further included. The adjustment member 209 is cylindrical, and a thread is provided on the side of the cylinder. A threaded hole is correspondingly provided on the claw piece 206. The adjustment member is vertically arranged on the outer side of the claw piece 206 through the thread, and the adjustment member 209 can abut against the mounting plate 210 of the first conveyor belt to adjust the opening distance of the clamping jaws to adapt to different bottle cap production environments.

[0030] In some other examples of this embodiment, the driving mechanism of the soft hammer 4 is a cylinder, which is arranged above the soft hammer 4. Specifically, the soft hammer can be made of soft plastic material, such as high-density polyethylene and polyurethane.

[0031] The working principle of the above-mentioned automatic correction capping machine is: the conveying speeds of the bottle body conveying mechanism and the bottle cap conveying mechanism are adjusted in advance, and then the interval time of the working of the capping mechanism and the soft hammer is set according to the conveying speeds of the bottle body conveying mechanism and the bottle cap conveying mechanism. The bottle body conveying mechanism continuously conveys the bottle body filled with relevant liquid to the left, and the bottle cap conveying mechanism synchronously conveys the bottle cap. The first pressing piece set on the first conveyor belt exerts a certain force on the bottle cap. The bottle cap leaves the first conveyor belt and at the same time opens the clamping jaws and leaves the clamping jaws. The second pressing piece knocks the bottle cap, and then the soft hammer descends and knocks the bottle cap, causing the bottle cap to drop a certain distance. Finally, the capping mechanism works to tighten the bottle cap.

[0032] Those skilled in the art will recognize that numerous variations to the foregoing description are possible, and that the examples and figures are intended only to describe one or more specific implementations.

[0033] Although what are considered exemplary embodiments of the present invention have been described and illustrated, it will be understood by those skilled in the art that various changes and substitutions may be made thereto without departing from the spirit of the present invention. In addition, many modifications may be made to adapt a particular situation to the teachings of the present invention without departing from the central concept of the present invention as described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but rather may include all embodiments and their equivalents falling within the scope of the present invention.
