Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an improved structure of a lateral limiting device of a weighing-type strong mixer. Background Art

[0002] A mixer is a mixing and molding machine that can mix multiple materials and make them into certain granular shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields. In many applications, such as fertilizers, medicines, food and other fields, materials need to be mixed and made into granules first.

[0003] In the prior art, a typical mixer is a weighing type high-power mixer. The structure of a weighing type high-power mixer includes a weighing seat and a high-power mixer main unit arranged on the weighing seat. In order to meet the weighing requirements of the high-power mixer and facilitate the control of the amount of feed, a number of weighing sensors are arranged under the weighing seat. Considering that the weighing type high-power mixer may shift due to vibration during operation, a special lateral limit device is usually required on the weighing seat.

[0004] The existing lateral limit device includes a limit support set on the weighing seat, a fixed support fixed on the foundation, and a limit rod is set between the limit support and the fixed support, and the two ends of the limit rod are respectively connected to the limit support and the fixed support hinge shaft. The problem is that: since the limit rod itself has a certain weight and is connected to the weighing seat, part of the weight of the limit rod will be loaded on the weighing seat; in addition, the vibration generated by the high-power mixer during operation will also be transmitted to the limit rod, causing the limit rod to vibrate up and down, and the acceleration load generated by the up and down vibration of the limit rod will also react on the weighing seat, so the weight measured by the weighing sensor includes both part of the weight of the limit rod itself and the vibration acceleration load of the limit rod, thereby reducing the accuracy of material weighing. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes an improved structure of the lateral limit device of a weighing type high-power mixer, aiming to improve the material weighing accuracy of the high-power mixer. The specific technical solution is as follows:

[0008] Preferably, the cross-sectional shape of the limiting rod is circular, and the upper portion of the supporting block is provided with an arc-shaped groove for supporting the limiting rod.

[0009] More preferably, the arc-shaped groove on the supporting block is a semicircular groove that is positioned and matched with the outer circle of the limiting rod.

[0010] Preferably, a height adjustment washer is provided on the lifting rod at a position between the coil spring and the upper end surface of the third support.

[0011] Preferably, the limiting head is a roller rotatably arranged on the end of the limiting rod.

[0012] As a further improvement of the utility model, a U-shaped fork is provided at the end of the limit rod, the vertical plate enters into the U-shaped gap of the U-shaped fork and a gap is provided between the two side surfaces of the U-shaped gap, and the roller serving as the limit head is rotatably arranged in the U-shaped gap of the U-shaped fork through a pin shaft.

[0013] Preferably, the roller is a rolling bearing.

[0014] As one of the preferred solutions of the limiting groove structure in the utility model, the limiting groove is a U-shaped groove with an opening at the bottom.

[0015] As one of the preferred solutions of the limiting groove structure in the utility model, the limiting groove is a waist-shaped groove.

[0016] Preferably, the number of the lateral limit devices is not less than four sets, and two of the four sets of lateral limit devices are used for limiting the left and right directions of the weighing seat (the limit rods are arranged along the left and right directions), and the other two sets of the four sets of lateral limit devices are used for limiting the front and rear directions of the weighing seat (the limit rods are arranged along the front and rear directions).

[0018] The beneficial effects of the utility model are:

[0019] First, the utility model provides an improved structure of the lateral limit device of a weighing-type high-power mixer. By opening a limit groove in the up-down direction on the vertical plate of the first support and arranging a floating elastic supporter for supporting the weight of the limit rod under the limit rod, the limit head of the limit rod is set to float up and down in the limit groove, thereby making the weight of the limit rod no longer act on the weighing seat, and the acceleration load energy generated by the up-and-down vibration of the limit rod will also be absorbed by the floating elastic supporter, thereby improving the material weighing accuracy of the high-power mixer.

[0020] Secondly, the utility model provides an improved structure of the lateral limit device of a weighing-type high-power mixer, in which an arc groove for positioning the outer circle of the limit rod is provided on the support block of the floating elastic supporter, thereby effectively limiting the lateral displacement of the limit rod, thereby keeping the U-shaped fork at the end of the limit rod from contacting the vertical plate (a gap is formed between the two sides of the vertical plate and the U-shaped fork), thereby eliminating the influence of the lateral vibration of the limit rod on the weighing accuracy.
