Technical Field

[0001] The utility model relates to the field of beverage processing equipment, in particular to an anti-distortion cover structure of a capping machine. Background Art

[0002] A capping machine is a mechanical device used to screw bottle caps onto bottle necks and is widely used in the beverage, food, and daily chemical industries. However, traditional capping machines lack a structure to prevent bottle misalignment, resulting in an offset between the position of the bottle and the end position of the capping machine. As a result, the bottle cap cannot be properly screwed onto the bottle neck when the capping machine is capping, and may become loose, skewed, or even fall off, causing damage to the product and equipment failure.

[0003] For example, the "capping machine" disclosed in the utility model patent (application number: 202021344642.0) discloses in its specification: it includes a frame, a conveying mechanism, a clamping and positioning mechanism, and a capping mechanism. The clamping and positioning mechanism includes two clamping devices located on both sides of the conveying mechanism. The capping mechanism is located above the conveying mechanism. The clamping device includes a clamping portion, a longitudinal adjustment portion that drives the holding portion to move up and down, and a transverse adjustment portion that drives the clamping portion to move back and forth. The clamping portion includes a housing with an active cavity and a circulating belt located within the active cavity. The opening of the active cavity is arranged toward the conveying mechanism. Drive rollers are provided at both ends of the circulating belt, forming a circular motion trajectory. Part of the circulating belt extends outside the opening of the active cavity, and a clamping area for positioning the bottle body is formed between the two oppositely arranged circulating belts. After the improvement, the scope of application of the capping machine is expanded, and the practicality and working quality of the capping machine are greatly improved. The above patent can prove the defects of the existing technology.

[0004] Therefore, we make improvements to this and propose an anti-distortion cover structure for a capping machine. Summary of the Invention

[0031] Further, such as Figure 2 and Figure 4 As shown, the mounting member includes a transmission plate 201 located at the top of the support plate 1. The transmission plate 201 is used to cooperate with the transmission member and the connecting member to move, thereby driving the telescopic assembly 2 to move. The transmission plate 201 is slidably connected to the support plate 1.

[0032] Further, such as Figure 1 and Figure 2 As shown, the sliding assembly 3 includes a limit frame 301 fixed to the rear end of the transmission plate 201, and two limit frames 301 are provided at the rear end of the transmission plate 201. The outer sliding of the limit frame 301 is provided with a limit plate 302 fixedly connected to the top of the support plate 1. The limit frame 301 and the limit plate 302 are used to cooperate with the movement of the transmission plate 201 to increase the stability of the transmission plate 201 when moving.

[0033] Further, such as Figure 2 and Figure 4 As shown, a mounting plate 601 is fixedly provided at the rear end of the support plate 1, and a transmission member includes a threaded rod 402 rotatably connected to the front end of the mounting plate 601. The threaded rod 402 rotates to cooperate with the connecting member to drive the transmission plate 201 and the telescopic component 2 to move. A motor 401 is fixedly provided at the rear end of the mounting plate 601. The output end of the motor 401 passes through the mounting plate 601 and is fixedly connected to the threaded rod 402. The threaded rod 402 is driven to rotate by starting the motor 401.

[0034] Further, such as Figure 2 and Figure 4 As shown, the connecting member includes a fixed cylinder 403 fixed to the rear end of the transmission plate 201, and the threaded rod 402 is connected to the internal thread of the fixed cylinder 403. When the threaded rod 402 rotates, it drives the fixed cylinder 403 and the transmission plate 201 to move forward.

[0035] Example 2

[0036] The anti-distortion cover structure of the capping machine provided in Example 1 is further optimized. Specifically, Figure 1 and Figure 2 As shown, the telescopic assembly 2 includes a sliding frame 202 fixed obliquely to the front end of the transmission plate 201. The two sliding frames 202 are arranged obliquely and symmetrically. A sliding rod 203 is provided inside the sliding frame 202 for sliding. The sliding rod 203 is used to cooperate with the function of sliding inside the sliding frame 202, so that the anti-slip pads 504 on both sides can be dispersed around the side of the bottle.

[0037] Further, such as Figure 2 and Figure 5 As shown, the elastic member includes a spring 204 fixed inside the slide frame 202. The spring 204 is used to increase the contact force between the rotating member and the bottle body, so as to achieve a better fixing effect and increase flexibility. At the same time, the slide rod 203 and the rotating member can adapt to bottles of more sizes. One end of the spring 204 is fixedly connected to the slide rod 203.

[0038] Further, such as Figure 2 and Figure 3 As shown, a connecting plate 502 is fixed to one side of the top and bottom ends of the slide bar 203, and the rotating member includes a limiting wheel 503 rotatably connected between the two connecting plates 502. The ends of the four slide bars 203 are each provided with a limiting wheel 503, and the limiting wheel 503 is used to contact the bottle body, and then cooperate with the transmission member, the inclination of the slide frame 202 and the elastic member to make the four anti-slip pads 504 move to the four sides, and the bottle is fixed in the middle by the elastic member.

[0039] Example 3

[0040] The anti-distortion cap structure of the capping machine provided in Example 1 and Example 2 is further optimized, such as Figure 3 As shown, an anti-skid pad 504 is fixed to the outside of the arc plate 501. The anti-skid pad 504 is used to better contact with the bottle to prevent slipping. The anti-skid pad 504 is specifically a rubber pad. Its soft properties can prevent the limiting wheel 503 from contacting the bottle and causing scratches on the bottle body.

[0041] Further, such as Figure 3 As shown, an arc plate 501 located on one side of the limiting wheel 503 is fixed to the end of the slide rod 203. The arc plate 501 is used to protect the limiting wheel 503 from contact with the outside world and reduce pollution from dust or foreign matter.

[0042] The use process of the anti-distortion cap structure of the capping machine provided by the utility model is as follows:

[0043] When the bottle needs to be positioned, the motors 401 on both sides are started to rotate the threaded rod 402, and the transmission plates 201 on both sides and the telescopic assembly 2 are driven to move toward the bottle in the middle through the fixed cylinder 403, so that the four limiting wheels 503 contact the two sides of the bottle. At this time, the sliding rod 203 continues to move so that it slides inside the sliding frame 202, and the contact force with the bottle body is increased by the spring 204, and the bottle is contacted with the bottle through the four anti-slip pads 504. Due to the inclined setting of the four telescopic assemblies 2, the four limiting wheels 503 are dispersed to the surrounding areas. The larger the bottle body is, the larger the dispersion range of the four limiting wheels 503 is, so that more bottle sizes can be accommodated; the bottle is located in the middle of the four limiting wheels 503, and then the bottle cap is tightened on the bottle mouth by the capping machine above.
