Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, in particular to a clamping mechanism of a palletizer. Background Art

[0002] A palletizer automatically stacks bags, cartons, or other packaging materials conveyed by a conveyor into stacks according to customer process specifications and then transports the stacked materials. The palletizer's primary control components, including programmable controllers, variable frequency speed controllers, proximity switches, pushbutton switches, and terminal blocks, are all top-quality, ensuring the reliability and longevity of the system hardware.

[0003] Application number: CN202122631135.6 discloses a new type of automatic palletizer. By setting an auxiliary manipulator assembly inside the manipulator assembly, it can facilitate the palletizing of items of different shapes, thereby simplifying the replacement process, facilitating the use of staff, and making the overall operation of the device more convenient. However, the above design still has shortcomings. Some large tubular objects are not easy to clamp. The mechanism relies solely on the locking structure on the moving wheel for positioning. There is a lack of a dedicated positioning mechanism. The mechanism is prone to displacement during operation.

[0004] To this end, we propose a clamping mechanism for a palletizer. Utility Model Content

[0005] The main purpose of the utility model is to provide a clamping mechanism for a palletizer. The electric cylinder in the box body pushes the positioning plate downward through the piston rod until the rubber pad on the lower end surface of the positioning plate is in close contact with the ground. The rubber pad increases the friction between the positioning plate and the ground, thereby achieving the purpose of positioning the palletizer body. The second clamp can follow the movement of the first clamp. The second clamp is provided with an arc groove on the side close to the clamping cavity. The tubular object to be clamped is placed in the clamping cavity, thereby improving the practicality of the mechanism and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A clamping mechanism of a palletizer, comprising a palletizer body, an electric telescopic rod, a clamping box, a first clamp and a base, wherein the palletizer body is mounted on the base, the base being a horizontally arranged rectangular plate-shaped structure, universal wheels being fixedly mounted at the four corners of the lower end surface of the base, a positioning plate being provided below the base, protrusions being provided at both ends of the upper end surface of the positioning plate, embedding grooves matching the protrusions being provided at both ends of the lower end surface of the base, a box being fixedly mounted at both ends of the upper end surface of the base, an electric cylinder being fixedly mounted inside the box, and the bottom end of the electric cylinder being connected to the positioning plate via a piston rod;

[0008] An electric telescopic rod is installed at the top of the palletizer body, and the end of the electric telescopic rod away from the palletizer body is connected to a clamping box, and the bottom end of the clamping box is connected to two sets of first clamps arranged opposite to each other, and one side of the first clamp is provided with a positioning mechanism for installing the clamping assembly;

[0009] The positioning mechanism includes a mounting seat, a threaded column and a nut. The clamping assembly includes a second clamp and an assembly rod. The top end of the second clamp is fixedly connected to the assembly rod.

[0010] By adopting the above technical solution, the rubber pad increases the friction between the positioning plate and the ground, thereby achieving the purpose of positioning the palletizer body, preventing the palletizer body from moving during operation, and thus improving the stability of the mechanism.

[0011] Specifically, the electric telescopic rod is arranged at a right angle to the palletizer body, and a limiting channel is provided between the two groups of the first clamps.

[0012] Specifically, two groups of the second clamps are provided opposite to each other, a clamping cavity is provided between the two groups of the second clamps, and the clamping cavity is located directly below the limiting channel.

[0013] Specifically, an anti-slip pad is fixedly glued to the lower end surface of the positioning plate, and the piston rod passes through the base.

[0014] Specifically, a mounting seat is fixedly connected to the center of the side of the first clamp away from the limiting channel, and one side of the top end of the assembly rod is buckled on the mounting seat;

[0015] A threaded column is vertically inserted into the center of one end of the mounting seat away from the first clamp, and one end of the threaded column passes through the assembly rod and is threadedly connected to the nut.

[0016] Specifically, an arc-shaped groove is provided on a side of the second clamp close to the clamping cavity, and a rubber pad is fixedly glued to one side of the arc-shaped groove of the second clamp.

[0017] Beneficial effects of the utility model:

[0018] (1) The clamping mechanism of a palletizer described in the present invention is such that the electric cylinder in the box pushes the positioning plate downwards through the piston rod until the rubber pad on the lower end surface of the positioning plate is in close contact with the ground. The rubber pad increases the friction between the positioning plate and the ground, thereby achieving the purpose of positioning the palletizer body and preventing the palletizer body from moving during operation, thereby improving the stability of the mechanism.

[0019] (2) The clamping mechanism of a palletizer described in the present invention is such that when a larger tubular object needs to be clamped, the upper part of one side of the assembly rod connected to the second clamp is buckled on the mounting seat, and one end of the threaded column passes through the assembly rod and is threadedly connected to the nut.
