Description

Technical Field

[0001] This utility model relates to a paper box chain spacing adjustment mechanism. Background Technology

[0002] Existing cartoning machines typically consist of a fixed platen and a movable platen. Each platen has two chains used to clamp the cartons. When the length of the cartons changes, the distance between the two plates needs to be adjusted. Due to the limitations of the chain dimensions, the minimum size of the cartons can be adjusted, thus limiting the range of carton adjustment.

[0003] To solve this problem, a three-chain cartoning machine was developed, consisting of a fixed platen and two movable platesn. Therefore, it is necessary to adjust the two platesn simultaneously. How to conveniently adjust the two movable platesn simultaneously is a problem that needs to be solved. Utility Model Content

A movable plate adjusting screw is provided inside the support tube. The movable plate adjusting screw consists of a first pitch section and a second pitch section. The pitch of the second pitch section is twice that of the first pitch section. A first nut is screwed onto the first pitch section, and a second nut is screwed onto the second pitch section. The support tube has an axially oriented movable plate adjustment window. The first movable plate is sleeved on the support tube via a first bushing. The first movable plate is connected to the first nut via a first key passing through the movable plate adjustment window. The second movable plate is sleeved on the support tube via a second bushing. The second movable plate is connected to the second nut via a second key passing through the movable plate adjustment window.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] As shown in the figure, the paper box chain spacing adjustment mechanism of this utility model includes: a fixed machine plate 2, a first movable machine plate and a second movable machine plate arranged in parallel; it also includes two parallel support tubes, which pass through the fixed machine plate, the first movable machine plate and the second movable machine plate respectively; the support tubes are fixedly mounted on the fixed machine plate. A movable plate adjusting screw is provided inside the support tube. The movable plate adjusting screw consists of a first pitch section and a second pitch section. The pitch of the second pitch section is twice that of the first pitch section. A first nut is screwed onto the first pitch section, and a second nut is screwed onto the second pitch section. The support tube has an axially oriented movable plate adjustment window. The first movable plate is sleeved on the support tube via a first bushing. The first movable plate is connected to the first nut via a first key passing through the movable plate adjustment window. The second movable plate is sleeved on the support tube via a second bushing. The second movable plate is connected to the second nut via a second key passing through the movable plate adjustment window.

[0017] Furthermore, chain guide rails are provided on the fixed machine plate, the first movable machine plate, and the second movable machine plate.

[0018] Furthermore, one end of the movable plate adjusting screw extends out of the support tube, and a synchronous sprocket is provided at the extended end of the movable plate adjusting screw; The timing sprockets of the two movable plate adjusting screws are connected by a chain.

[0019] The system includes a fixed machine plate 2, a first movable machine plate 5, and a second movable machine plate 10 arranged in parallel; it also includes two parallel support tubes 21, which pass through the fixed machine plate, the first movable machine plate, and the second movable machine plate respectively; the support tubes 21 are fixedly mounted on the fixed machine plate 2. The support tube 21 passes through the first bushing 20 and the second bushing 16 in sequence. The support tube 21 and the bushing are separated by sliding sleeves 7 and 11, so that the first bushing 20 and the second bushing 16 can slide freely on the support tube 21.

[0020] The first bushing 20 is fixed to the first movable plate 5 with screws, and the second chain guide rail 6 is fixed to the first movable plate 5 with screws. When the first bushing 20 moves, it can drive the second chain guide rail 6 to move together.

[0021] The second bushing 16 is fixed to the second movable plate 10 with screws, the third connecting plate 9 is fixed to the second movable plate 10 with screws, and the third chain guide rail 8 is fixed to the third connecting plate 9 with screws.

The first pitch section 1 and the first nut 18 have the same pitch, forming a fit; the first pitch section 13 and the second nut 14 have the same pitch, also forming a fit. The first nut 18 is connected to the first bushing 20 by a second key 19, which is then connected to the first bushing 20 by screws. The second nut 14 and the second bushing 16 are connected by a first key 15, which is also connected to the second bushing 16 by screws. The sprocket 12 is fastened to the first pitch section 13 of the lead screw by screws.

[0023] When the rotating chain 23 simultaneously drives both lead screws to rotate at the same speed, it ensures smooth movement of the movable plate. When the first pitch segment 1 of the lead screw rotates, the first pitch segment 1 drives the locking sleeve 17 and the first pitch segment 13 of the lead screw to rotate together. The first nut 18 moves linearly along the axis of the first pitch segment 1 of the lead screw, while the second nut 14 moves linearly along the axis of the first pitch segment 13 of the lead screw. The first nut 18 drives the first bushing 20 to move via the second key 19, thereby driving the first movable plate 5 and the second chain guide 6 to move. The second nut 14 drives the second bushing 16 to move via the first key 15, thereby driving the second movable plate 10, the third connecting plate 9, and the third chain guide 8 to move together.
