TECHNICAL FIELD
[0001] The utility model relates to the technical field of automation packaging, especially relates to a locking adjustable bottle body clamp. BACKGROUND
[0002] In recent years, more and more high-grade daily chemical product packages adopt multi-attitude and colorful bottle body packages, greatly improving the product package level and being more popular. Due to the particularity of the bottle body, the bottle body is mostly circular structure, and some bottle bodies are square, triangular structure, etc. In the production process, the bottle body is transmitted on the transmission line, and will undergo filling, marking, bottle plug pressing and other operations. In this process, the stability of the bottle body on the transmission line needs to be ensured.
[0003] If the bottle body is large, it can also ensure a certain stability during the transmission process on the transmission line. However, it is difficult to ensure the stability of the bottle body during the transmission process for a small bottle body. The traditional operation mode is to use a simple limiting block or limiting clamp to limit the bottle body. However, the limiting block or limiting clamp is difficult to disassemble, clean and maintain in this way. Moreover, the applicability of the limiting clamp is poor for different bottle bodies, and it is difficult to apply to various bottle body structures.
[0004] For different sizes of bottle body, the existing technology realizes synchronous adjustment of the clamping jaw by driving the two side nut blocks through the positive direction screw rod during the simultaneous adjustment of the two sides. However, this adjustment mode needs relatively accurate positive and negative screw rods as support, which may increase the cost. Alternatively, the utility model patent with the patent number 2025202475028 and the patent name "adjustable bottle mold" discloses a bottle body clamp. The bottle body clamp is provided with a longitudinal sliding block that slides up and down in the base. The distance between the two clamping jaws on the two sides is adjusted through the longitudinal sliding block, which is convenient for adjustment. However, the adjustment structure does not have a locking structure. During the clamping of the bottle body, there is a certain clamping force between the clamping jaw and the bottle body.

The opposite surfaces of the upper end surface tooth 206 and the lower end surface tooth 207 are provided with tooth surfaces. The inner wall of the base 2 is further provided with a limiting mechanism. The limiting mechanism is used for limiting the rotation of the upper shaft sleeve 208 and limiting the up-down movement distance of the upper shaft sleeve 208.
[0042] The limiting mechanism comprises a limiting disc 210, a gap is arranged between the limiting disc 210 and the upper shaft sleeve 208, a limiting column 212 is further arranged at the lower end of the limiting disc 210, a first sliding notch 213 is further arranged on the upper shaft sleeve 208 at the position corresponding to the limiting column 210, the limiting column 212 slides up and down on the first sliding notch 213, an elastic member is connected to the lower end of the limiting disc 210, and the elastic member is sleeved on the outer wall of the upper shaft sleeve 208. In the embodiment, the elastic member is designed as a spring 211.
[0043] When the upper end surface teeth 206 and the lower end surface teeth 207 are engaged, the elastic member is in a normal state, and when the upper end surface teeth 206 and the lower end surface teeth 207 are separated, the elastic member is in a compressed state.

[0046] In the embodiment, the structure of the clamping jaw 1 is not changed, and specific reference is made to the utility model patent with the application number 2025202475028 and the patent name “adjustable bottle mold”. A horizontal second sliding notch 101 is arranged on the surface of the base 2 and in the sliding direction of the clamping jaw 1, the upper end of the connecting plate 204 is arranged below the clamping jaw 1 through a connecting rod (not shown in the figure), and the connecting rod slides in the second sliding notch 101.
[0047] Working principle:
[0048] When the distance between the clamping jaws 2 needs to be adjusted, the rotating shaft 201 is manually pushed upward by using a hexagonal tool or is pushed upward by a servo motor combined with an electric push rod. During the upward movement, because the lower shaft sleeve 209 is connected to the rotating shaft 210 in a sliding manner, the lower shaft sleeve 209 and the lower end surface teeth 207 do not move upward with the rotating shaft 209, and the rotating shaft 201 drives the upper shaft sleeve 208 and the upper end surface teeth 206 thereon to move upward. During the upward movement, the upper shaft sleeve 208 compresses the spring 211, and the limiting column 212 moves up and down in the first sliding slot 213. After moving a certain distance, the upper end surface teeth 206 are separated from the lower end surface teeth 207. After the rotating shaft 201 is pushed to the position, because the limiting column 212 is in the first sliding slot 213, the limiting column 212 is also fixed and does not move, which limits the rotation of the upper shaft sleeve 208. Therefore, during the rotation of the rotating shaft 201, the upper shaft sleeve 208 does not rotate with the rotating shaft 201 because of the action of the first bearing 215, so that the gear 202 drives the transverse rack 203 to rotate, and the distance adjustment is realized. After the distance adjustment is completed, the force for pushing the rotating shaft 201 upward is released, and under the action of the spring 211, the upper shaft sleeve 208 moves downward, driving the rotating shaft 201 to move downward until the upper end surface teeth 206 are engaged with the lower end surface teeth 207. After the engagement, the rotating shaft 201 cannot be rotated again because the upper and lower end surface teeth are engaged. If the rotating shaft 201 is rotated, the upper and lower end surface teeth will be rotated together, but because the upper shaft sleeve cannot be rotated under the action of the first sliding slot 213 and the limiting column 212, and the rotating shaft 201 and the upper shaft sleeve 208 are connected in a rotating manner through the first bearing 215, the upper shaft sleeve 208 cannot be rotated, which leads to the fact that the entire rotating shaft 201 cannot be rotated, and a locking state is realized.
[0049] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent transformation or modification according to the spirit and essence of the present application should be covered within the protection scope of the present application.
