Description

Technical Field

[0001] This utility model belongs to the field of tobacco production technology, specifically relating to an adjustable bracket for a proximity switch of a hydraulic box-turning machine. Background Technology

[0002] The tobacco sheet processing step on the tobacco processing line mainly involves vacuum rehydration of the tobacco sheets packed in steel turnover boxes, followed by the hydraulic box-turning machine pouring the tobacco sheets from the steel turnover boxes into a loosening and unpacking machine for further processing before they enter the next processing step.

[0003] Hydraulic crate tipping machines use proximity switches installed at the front and sides of the frame to sense whether the crates have reached the correct position. A hydraulic cylinder then drives the crates to tip over after vacuum rehydration. Currently, the proximity switch mounting brackets are fixed to the frame with screws. The mounting positions of both the brackets and the proximity switches are relatively fixed, with no room for adjustment. This can easily cause abnormal proximity switch sensing, leading to frequent malfunctions in the hydraulic crate tipping system.

[0004] Therefore, how to design an adjustable bracket for the proximity switch of a hydraulic box tipper, so that the installation positions of both the bracket and the proximity switch are adjustable, has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable bracket for a proximity switch of a hydraulic box-turning machine, so as to solve the above-mentioned technical problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable bracket for a proximity switch of a hydraulic box-turning machine includes an inverted U-shaped frame. The front side plate of the inverted U-shaped frame has a first elongated hole extending horizontally, and the rear side plate of the inverted U-shaped frame has a second elongated hole extending horizontally. The first elongated hole is for the threaded section of a first fixing screw to pass through, and the proximity switch has a first threaded hole for engaging with the threaded section of the first fixing screw. The second elongated hole is for the threaded section of a second fixing screw to pass through, and the frame of the hydraulic box-turning machine has a second threaded hole for engaging with the threaded section of the second fixing screw.

[0008] Preferably, the inverted U-shaped frame is made of stainless steel.

[0009] Preferably, the corners of the inverted U-shaped frame have an arc-shaped structure.

[0010] Preferably, the first elongated hole and the second elongated hole are arranged opposite to each other.

[0011] Preferably, the first elongated hole is located near the lower end of the front side plate.

[0012] Preferably, the second elongated hole is located near the lower end of the rear side plate.

[0013] Preferably, the thickness of the inverted U-shaped frame is 1.5mm to 2.5mm.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model discloses an adjustable bracket for a proximity switch in a hydraulic box-turning machine. In use, loosening the first fixing screw and then moving it left and right within the first elongated hole allows for easy adjustment of the proximity switch's mounting position on the front panel of the inverted U-shaped frame. Loosening the second fixing screw allows for left and right movement of the inverted U-shaped frame, which has a second elongated hole on the rear panel that engages with the second fixing screw. This facilitates further adjustment of the inverted U-shaped frame's mounting position on the hydraulic box-turning machine frame, thereby also adjusting the mounting position of the proximity switch on the front panel. This expands the adjustment range of the proximity switch's mounting position and improves its adjustability. Therefore, this utility model allows both the inverted U-shaped bracket and the proximity switch to be adjustable, and provides a large adjustment range for the proximity switch's mounting position, thus reducing the likelihood of sensing abnormalities and ensuring the normal operation of the hydraulic box-turning machine.

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] like Figures 1 to 3 As shown, this utility model embodiment provides an adjustable bracket for a proximity switch of a hydraulic box-turning machine, which includes an inverted U-shaped frame. The front side plate 11 of the inverted U-shaped frame is provided with a first elongated hole 21 extending horizontally, and the rear side plate 12 of the inverted U-shaped frame is provided with a second elongated hole 22 extending horizontally. The first elongated hole 21 is used for the threaded section of a first fixing screw to pass through, and the proximity switch is provided with a first screw hole for cooperating with the threaded section of the first fixing screw. The second elongated hole 22 is used for the threaded section of a second fixing screw to pass through, and the frame of the hydraulic box-turning machine is provided with a second screw hole for cooperating with the threaded section of the second fixing screw.

[0028] The adjustable bracket for the proximity switch of a hydraulic box-turning machine provided in this embodiment allows for easy adjustment of the proximity switch's mounting position on the front panel of the inverted U-shaped frame by loosening the first fixing screw and moving it left and right within the first elongated hole 21. Loosening the second fixing screw allows for left and right movement of the inverted U-shaped frame through the second elongated hole 22 on the rear panel, further facilitating adjustment of its mounting position on the hydraulic box-turning machine frame. This, in turn, adjusts the mounting position of the proximity switch on the front panel, expanding the adjustment range and improving its adjustability. Therefore, this invention allows for adjustable mounting positions of both the inverted U-shaped bracket and the proximity switch, with a wider adjustment range for the proximity switch, reducing the likelihood of sensor malfunctions and ensuring the normal operation of the hydraulic box-turning machine.

[0029] Furthermore, the inverted U-shaped frame is made of stainless steel, making it more durable and less prone to damage.

[0030] Specifically, the corner of the inverted U-shaped frame is an arc-shaped structure 14, which can better prevent the corner of the inverted U-shaped frame from causing scratches to maintenance personnel or other parts.

[0031] In one embodiment, the first elongated hole 21 and the second elongated hole 22 are arranged opposite to each other.

[0032] In another embodiment, the first elongated hole and the second elongated hole can be staggered to provide more operating space for the first fixing screw and the second fixing screw, so as to facilitate disassembly and installation.

[0033] Preferably, the first elongated hole 21 is disposed near the lower end of the front side plate 11, and the second elongated hole 22 is disposed near the lower end of the rear side plate 12, thereby facilitating the adjustment work.

[0034] Specifically, the thickness of the inverted U-shaped frame is 1.5mm to 2.5mm.

[0035] Preferably, the first elongated hole 21 is located in the middle of the lower end near the front side plate, and the second elongated hole 22 is located in the middle of the lower end near the rear side plate.

[0036] Specifically, there are two first fixing screws and two second fixing screws. The two second fixing screws ensure a more secure and reliable connection between the rear panel of the inverted U-shaped frame and the hydraulic box-turning machine frame, while the two first fixing screws ensure a more secure and reliable connection between the proximity switch and the front panel of the inverted U-shaped frame. It is understood that there are also two first screw holes and two second screw holes, each corresponding to a first fixing screw. When the inverted U-shaped frame and the proximity switch are adjusted to the required positions, tightening the first and second fixing screws will fix the inverted U-shaped frame to the corresponding position on the hydraulic box-turning machine frame using the second fixing screws, and will also fix the proximity switch to the corresponding position on the front panel using the first fixing screws.

[0037] In one specific embodiment, the thickness of the inverted U-shaped frame can be 2mm, the front and rear side plates have the same dimensions, that is, the length is 100mm and the width is 60mm, and the length and width of the top plate of the inverted U-shaped frame are both 100mm; the first elongated hole and the second elongated hole have the same dimensions, that is, the length is 80mm and the width is 6.5mm.

[0038] The general operating process of this utility model is as follows: When the hydraulic crate tilting machine lifts the steel turnover box and the steel turnover box is flipped to the position of the proximity switch, the proximity switch senses the steel turnover box and sends an electrical signal to the controller. The controller then controls the hydraulic system of the hydraulic crate tilting machine to stop working. At the same time, the tobacco flakes inside the steel turnover box are poured into the loosening and unloading machine. After a 5-second delay, the hydraulic system of the hydraulic crate tilting machine resumes operation, returning the empty steel turnover box to its original position. Throughout the entire working process, every movement of the steel turnover box can be sensed by the proximity switch, ensuring the stable operation of the hydraulic crate tilting machine, preventing equipment failures during production, and also saving maintenance costs.

[0039] The installation positions of the inverted U-shaped frame, the hydraulic crate turnover machine frame, and the proximity switch in this invention can all be adjusted according to the specific equipment conditions. The second elongated hole allows the adjustable bracket to move left and right on the hydraulic crate turnover machine frame, while the proximity switch can be fixed at any position within the first elongated hole. This significantly increases the adjustment margin of the proximity switch, expands its sensing range, and makes adjustment convenient and quick, ensuring the normal operation of the hydraulic crate turnover machine, eliminating equipment malfunctions caused by the proximity switch failing to sense steel turnover boxes, and improving production efficiency.

[0040] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
