Description

Technical Field

[0001] The utility model belongs to the field of checkweighers, and in particular relates to a checkweigher with a leg adjustment structure. Background Art

[0002] During the processing of product production lines, finished products need to be weighed. The existing technology has a belt-type checkweigher that combines product transmission and automatic weighing. For conventional equipment on production lines, general checkweighers have leg height adjustment, so that the device can be modularly assembled to meet the needs of different production lines.

[0003] There are many existing ways to adjust the height of the legs. Most common adjustment structures are essentially driven by a threaded structure. However, when the threaded structure is not tightened, there is a thread return gap. General thread adjustment does not have a locking function. When the mechanical equipment on the production line vibrates, the adjustment structure of the threaded structure is also easily affected by the vibration and becomes loose, and it is easy to generate noise. Utility Model Content

[0004] The purpose of the present utility model is to provide a checkweigher with a leg adjustment structure in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A checkweigher with a leg adjustment structure includes a checkweigher frame and several legs with external threads, wherein the checkweigher frame extends an internally threaded collar to the side, and each leg is paired with two internally threaded collars. The surface of the checkweigher frame is also provided with a sliding pressure block, which is driven to squeeze between the two internally threaded collars to make the two internally threaded collars have deformation tendencies in opposite directions.

[0007] As a further optimization scheme of the present invention, a foot is provided at the bottom of the leg, wherein the foot is rotatably connected to the leg, and a nut structure for easy rotation is provided on the surface of the leg. The foot is fixed to the ground by friction, and the nut is provided for facilitating the use of tools to drive the leg to rotate.

[0008] As a further optimization scheme of the present invention, the clamping block is driven by a knob arranged on the surface of the checkweigher frame, wherein a chamber is arranged on the surface of the checkweigher frame, the knob and the clamping block penetrate into the chamber from opposite directions, the shaft of the clamping block is slidably connected to the chamber, and the shaft located in the chamber is provided with an extension portion, and the surfaces of the two extension portions are provided with a slope for pushing the clamping block. By providing two extension portions facing each other, when one of the extension portions rotates, the other extension portion is pushed to slide by the slope.

[0009] As a further optimization scheme of the present invention, the surface of the extension part is also provided with an abutment surface connecting the slope surface, and the abutment surfaces of the two extension parts are respectively provided with a card groove and a card strip. This scheme further provides an abutment surface and a card groove, which are used to increase the stability of the two extension parts after being tightened.

[0010] As a further optimization solution of the present invention, the pressing block is arc-shaped and semi-enclosed on the side of the supporting leg.

[0011] The beneficial effects of the present invention are:

[0012] The utility model provides two internal threaded collars that are threadedly connected to the support legs, which plays the role of thread lifting and lowering, and a clamping block is provided between the two internal threaded collars, which is used to push the two internal threaded collars apart in opposite directions, so that the internal threaded collars undergo slight deformation. The slight deformation causes the upper and lower internal threaded collars and the threaded structure of the support legs to be subjected to force in opposite directions, thereby eliminating the thread gap and effectively preventing vibration.

[0019] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1-5As shown, a checkweigher with a leg adjustment structure includes a checkweigher frame 1 and several legs 2 with external threads, wherein the checkweigher frame 1 extends an internally threaded collar 3 to the side, and each leg 2 is paired with two internally threaded collars 3, wherein the surface of the checkweigher frame 1 is also provided with a sliding clamping block 41, which is driven to squeeze between the two internally threaded collars 3 to make the two internally threaded collars 3 have deformation tendencies in opposite directions.

[0022] This solution achieves the effect of thread lifting by setting two internally threaded collars 3 for threaded connection with the support leg 2, and a clamping block 41 is set between the two internally threaded collars 3, which is used to push the two internally threaded collars 3 in opposite directions, so that the internally threaded collars 3 undergo slight deformation. This slight deformation causes the upper and lower internally threaded collars 3 and the threaded structure of the support leg 2 to be subjected to force in opposite directions, thereby eliminating the thread gap and effectively preventing vibration.

[0023] A foot 21 is provided at the bottom of the leg 2, wherein the foot 21 is rotatably connected to the leg 2, and a nut structure for easy rotation is provided on the surface of the leg 2. There is friction between the foot 21 and the ground for fixation, and the nut is provided for facilitating the use of tools to drive the leg 2 to rotate.

[0024] The clamping block 41 is driven by a knob 42 provided on the surface of the checkweigher frame 1, wherein the surface of the checkweigher frame 1 is provided with a chamber 11. The knob 42 and the clamping block 41 penetrate into the chamber 11 from opposite directions. The shaft of the clamping block 41 is slidably connected to the chamber 11. The shaft located in the chamber 11 is provided with an extension 43. The surfaces of the two extensions 43 are provided with a slope 44 for pushing the clamping block 41. By providing two extensions 43 facing each other, when one extension 43 rotates, the slope 44 pushes the other extension 43 to slide. The clamping block 41 is semi-enclosed in an arc shape on the side of the support leg 2. The surfaces of the two ends of the clamping block 41 that contact the internal threaded sleeve 3 are matched, so that the clamping block 41 can support the internal threaded sleeve 3 upward / downward during the clamping process.

[0025] Furthermore, the surface of the extension portion 43 is also provided with an abutting surface 45 connecting the slope surface 44, and the abutting surfaces 45 of the two extension portions 43 are respectively provided with a card slot 47 and a card strip 46. The abutting surface and the card slot are provided to increase the stability of the two extension portions after they are tightened. Specifically, when one extension portion 43 rotates to push the other extension portion 43 to slide, after the pushing is completed, the abutting surface 45 contacts each other to improve the stability, and the card strip 46 and the card slot 47 are provided to prevent the extension portion 43 connected to the knob 43 from rotating.

[0026] The specific implementation method is as follows: when the height needs to be adjusted, rotate the knob 42 so that the two extensions 43 abut the surfaces 45 to each other, and the clamping block 41 does not have the force to squeeze between the two internally threaded collars 3. An elastic structure can be provided here to help the clamping block 41 rebound, and then the height is adjusted by rotating the support leg 2. After the adjustment is completed, rotate the knob 42 again to make the slopes 44 abut against each other, and the clamping block 41 is pushed to support the two internally threaded collars 3 to both sides, especially the upper internally threaded collar 3, which undergoes slight deformation to change the force direction of the threaded structure. Since the return clearance of the threaded structure is relatively small, the degree of deformation does not affect the load-bearing capacity of the internally threaded collar 3. After locking the internally threaded collar 3 from different directions, the vibration problem caused by the threaded structure is eliminated.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
