Description
Technical Field
[0001] The utility model relates to the technical field of product detection, in particular to a metal detection and weighing integrated machine with an adjustment and protection structure. Background Art
[0002] In the technical field of product detection, especially in metal detectors and checkweighers, metal detection and weighing integrated machines and dynamic checkweighers are widely used in various industries. Their main function is to weigh products to ensure that the product weight meets enterprise and regulatory requirements.
[0003] Currently, if we want to weigh products, the usual practice is to select a weighing sensor with an appropriate range according to product requirements and directly install it on the conveyor frame. Then, continue to install the conveyor tabletop above the weighing sensor, and adjust the four-corner deviation before testing and verification. After the above conventional process is completed, finally, the whole device can be packaged and sent to customers through logistics transportation.
[0004] However, during the installation and overall transportation of the weighing sensor, the following problems may usually exist:
[0005] First, large weighing table tops are often heavy. After installing the weighing sensor, if it is impacted by external forces, it is very easy to cause damage to the sensor.
[0006] Second, after installing the weighing tabletop, it is necessary to finely adjust the position of the weighing sensor to ensure the accurate installation position and uniform force of the sensor. However, the weight of the tabletop is often relatively heavy, and it is necessary for multiple people to slightly lift the tabletop simultaneously and then manually fine-tune the sensor position to achieve the adjustment. This method is time-consuming and laborious.
[0007] Third, during the overall transportation of the machine, due to the complex road conditions, it is very easy for the weighing sensor to be damaged due to large forces caused by impact vibration.
[0008] Fourth, for the metal detection and weighing integrated machine, eddy current loops are likely to form in the sensor and other parts, affecting the performance of the metal detection head.
[0009] In view of this, the inventor of this application designed a metal detection and weighing integrated machine with an adjustment and protection structure in order to overcome the above technical problems. Utility Model Content

[0035] Embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. Preferred embodiments of the present utility model will now be described in detail, which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals will be used throughout the drawings to represent the same or similar parts.
[0036] In addition, although the terms used in the present utility model are selected from well-known and commonly used terms, some of the terms mentioned in the specification of the present utility model may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the description herein.
[0037] In addition, it is required to understand the present utility model not only by the actual terms used, but also by the meaning implied by each term.
[0038] As Figures 1 to 4 shown, the present utility model discloses a metal detection and weighing integrated machine with an adjustable protection structure, which includes: a frame 10, a conveyor frame 20, at least one weighing component 30, a plurality of adjusting components 40, and a weighing table 50. The conveyor frame 20 is disposed parallel to the upper part of the frame 10, and the weighing table 50 is installed on the conveyor frame 20.
[0039] An installation block and an installation seat (not shown in the figure) may also be provided between the weighing table 50 and the frame 10. The installation seat fixes the installation block, and an oblong hole for height adjustment is provided on the installation block, and the position can be adjusted according to requirements, and fine adjustment of the sensor and transportation protection can also be achieved.
[0040] The weighing components 30 are respectively arranged at the side parts of the frame 10 (for example, at the four top corners of the frame 10 in this embodiment, as Figure 4 shown), and are fixed between the conveyor frame 20 and the frame 10.
[0041] For example, preferably, at each top corner or each side of the frame 10, a weighing sensor 30 is correspondingly installed. A first fixing hole 21 is provided on the conveyor frame 20, and a second fixing hole 11 is provided on the frame 10. The first end of each weighing sensor 30 is fixedly connected to the first fixing hole 21, and the second end is fixedly connected to the second fixing hole 11.
[0042] Further preferably, a weighing sensor insulating sleeve 60 is installed in the first fixing hole 21, and the upper connecting rod of the weighing sensor 30 is inserted into the weighing sensor insulating sleeve 60. Setting the weighing sensor insulating sleeve 60 in the first fixing hole 21 of the conveyor frame 20 can prevent the formation of an eddy current loop between the conveyor table and the frame, and avoid affecting the performance of the metal detection head.
[0043] Here, the weighing assembly 30 can preferably be a bellows weighing sensor, which includes an upper connecting rod 31, a steel ball 32, a lower connecting rod 33 and a lower sensor 34. The steel ball 32 is installed in the accommodating space formed by the arc surface of the upper connecting rod 31 and the arc surface of the lower connecting rod 33, and the lower connecting rod 33 is vertically connected to the lower sensor 34. The upper connecting rod 31 is fixedly connected to the first fixing hole 21 as the first end of the weighing assembly 30, and the lower sensor 34 is fixedly connected to the second fixing hole 11 as the second end of the weighing assembly 30.
[0044] As Figure 2 and Figure 3 shown, the adjusting assemblies 40 are respectively arranged at the side parts of the frame 10, adjacent to the corresponding weighing assemblies 30 (for example, selected at the four top corners of the frame 10 in this embodiment, as Figure 4 shown).
[0045] For example, preferably, at each side part of the frame 10, an adjusting assembly 40 is correspondingly installed. A first positioning hole 22 is provided on the conveyor frame 20, and a second positioning hole 12 is provided on the frame 10. Here, the first positioning hole 22 and the second positioning hole 12 need to be vertically aligned (for example, coaxially). Each adjusting assembly 40 passes through and is positioned in the corresponding first positioning hole 22 and second positioning hole 12 for connecting and supporting the conveyor frame 20 and the frame 10.
[0046] Preferably, in this embodiment, each adjusting assembly 40 can preferably include an adjusting screw 41, a first fastener 42 and a second fastener 43 (here, the second fastener 43 can also be omitted without setting, and the adjusting screw 41 can also be fixed). The adjusting screw 41 is passed through the first positioning hole 22 and the second positioning hole 12. The first fastener 42 is sleeved on the adjusting screw 41 for fixing the position of the adjusting screw 41 and the first positioning hole 22. The second fastener 43 is sleeved on the adjusting screw 41 for fixing the position of the adjusting screw 41 and the second positioning hole 12.
[0047] In this embodiment, the adjusting screw 41 is selected as a full-length thread, passes through and penetrates the second positioning hole 12 and the first positioning hole 22, is arranged at the four corners of the frame 10, and the number is four respectively. The conveyor frame 20 and the frame 10 are connected and supported by tightening the first fastener 42 and the second fastener 43 respectively. In this way, on the one hand, it can support the weight of the entire weighing table 50, on the other hand, it provides an installation space for the weighing assembly 30 in the height direction, and it is also convenient for subsequent installation of the weighing table 50 and adjustment of the weighing assembly 30.
[0048] In particular, an insulating sleeve 70 is installed between the adjusting screw 41 and the first positioning hole 22. By arranging the insulating sleeve 70 in the first positioning hole 22 of the conveyor frame 20, it is possible to prevent the formation of an eddy current loop between the conveyor table surface and the machine frame, thus avoiding affecting the performance of the metal detection head. Here, the insulating sleeve 70 that isolates the adjusting screw 41 is respectively arranged in the first positioning hole 22 of the conveyor frame 20, which can prevent the formation of an eddy current loop between the conveyor frame and the machine frame from affecting the performance of the metal detection head.
[0049] Before the weighing assembly 30 works (i.e., in the transportation state), the first fastener 42 jacks up the conveyor frame 20 upward, maintaining a gap a between the insulating sleeve 70 and the end face of the conveyor frame 20, which can avoid overloading and failure of the weighing assembly 30 caused by large external forces or impact vibrations generated during transportation.
[0050] Furthermore, the first end portion 411 of the adjusting screw 41 is located in the first positioning hole 22, and a dust-proof cover 80 is installed on the first end portion 411. The dust-proof cover 80 is located above the first positioning hole 22 and fits against the end face of the conveyor frame 20, which can effectively prevent dust or foreign objects from falling into the first positioning hole 22.
[0051] For example, an internal threaded hole is provided in the first end portion 411 of the adjusting screw 41, and the dust-proof cover 80 is fixedly connected to the first end portion 411 of the adjusting screw 41 through a fixing member 81. By providing a dust-proof sleeve at the top of the adjusting screw, it is possible to prevent foreign objects on the weighing table surface from falling into the holes of the conveyor frame, thereby affecting the function of the adjusting screw.
[0052] The dust-proof cover 80 is flush with the end face of the conveyor frame 20 and is provided with hole positions for installing bolts. The fixing member 81 (such as a fixing bolt) connects the dust-proof cover 80 and the adjusting screw 41 together through the bolt hole positions of the dust-proof cover 80. By providing the dust-proof sleeve 80 here, it is possible to prevent foreign objects on the weighing table surface from falling into the holes of the conveyor frame 20, avoiding affecting the function of the adjusting screw.
[0053] Preferably, the dust-proof cover 80 is made of an insulating material, and the size of the dust-proof cover 80 is larger than the size of the first positioning hole 22. This can prevent unpackaged foreign objects on the weighing table surface from falling into the positioning holes 9 on the conveyor frame 3, thereby avoiding problems such as damage and failure of the threads of the adjusting screw 5.
[0054] Before the initial installation of the weighing assembly 30, an insulating sleeve 70 is installed in the first positioning hole 22 of the conveyor frame 20. Here, the insulating sleeve 70 is selected to be made of an insulating material, is provided with a flange edge, and the flange edge is installed downward.
[0055] After the first fastener 42 and the second fastener 43 are tightened respectively, a certain installation space is reserved between the conveyor frame 20 and the frame 10. The flange edge of the insulating sleeve 70 fits against the conveyor frame 20, which can ensure that the adjusting screw 41 does not come into direct contact with the first positioning hole 22 of the conveyor frame 20.
[0056] When arranging the metal detection and weighing integrated machine, it can be avoided that the conveyor frame 20 and the frame 10 form an eddy current loop through the adjusting screw 41 to interfere with the metal detection head. The weighing components 30 are arranged at the four corners of the frame 10, and the number is 4 respectively. The lower sensor 34 of the weighing component 30 is connected to the bottom fixing hole (i.e., the second fixing hole 11) of the frame 10 through bolts. The lower connecting rod 33 is connected to the lower sensor 34 through bolts at the lower part, and steel balls 32 are placed at the upper part, and a dust-proof sleeve 35 is wrapped around the circumference.
[0057] A weighing sensor insulating sleeve 60 is installed in the first fixing hole 21. Here, the weighing sensor insulating sleeve 60 is preferably made of insulating material, and the upper connecting rod 31 is placed inside. At this time, the second fastener 43 needs to be loosened upward appropriately so that the upper connecting rod 31 contacts the steel ball 32 at the lower part and is connected to the conveyor frame 20 through the upper insulating pad 36 and the fastener at the upper part. Here, the weighing sensor insulating sleeve 60 for isolating the weighing component 30 is arranged in the first fixing hole 21 of the conveyor frame 20, which can prevent the conveyor frame and the frame from forming an eddy current loop and affecting the performance of the metal detection head.
[0058] Here, the upper insulating pad 36 is preferably made of insulating material. The weighing sensor insulating sleeve 60 and the upper insulating pad 36 are arranged at three places of the four weighing components 30 on the frame 10. At these three places, the conveyor frame 20 and the frame 10 cannot form an eddy current through the weighing component 30 to interfere with the metal detection head. At the remaining one place, a weighing sensor insulating sleeve 60 and a metal gasket are used, which can make the conveyor frame 20 and the frame 10 conduct through the weighing component 30. When static electricity accumulates on the conveyor table due to the conveyed products, after the conveyor frame 20 and the frame 10 are conducted, it is beneficial to discharge the static electricity, playing a role in protecting the operator.
[0059] After the weighing component 30 and the weighing table 50 are installed, adjustment and testing are still required. Before the weighing component 30 works, the first fastener 42 can be loosened downward appropriately to control the gap a between the end face of the insulating sleeve 70 and the end face of the conveyor frame 20 to be greater than or equal to 0.5 mm (for example, the gap a can be preferably 0.5 mm). This can prevent the weighing component 30 from being overloaded due to a sudden increase in the test external force and avoid its damage.
[0060] That is to say, when the metal detection and weighing integrated machine is in the transportation state, loosen the first fastener 42, jack up the conveyor frame, and a gap a is formed between the insulating sleeve 70 and the end face of the conveyor frame 20, so as to prevent the conveyor frame 20 from transmitting force to the weighing sensor.
[0061] When the metal detection and weighing integrated machine is in the working state, put down the first fastener 42, so that the conveyor frame 20 can be loaded onto the weighing sensor, enabling the weighing sensor to weigh.
[0062] During the logistics transportation of the equipment, the second fastener 43 remains stationary, and the first fastener 42 can be appropriately tightened upward to make the flange edge of the insulating sleeve 70 fit the conveyor frame 20. At this time, the adjusting screw 41 and the weighing assembly 30 can jointly support the weight of the weighing table 50 and withstand the impact and vibration brought by transportation, preventing damage and failure of the weighing assembly 30.
[0063] According to the above description, the metal detection and weighing integrated machine of the present utility model with an adjustment and protection structure realizes the functions of weighing assembly installation adjustment and transportation protection with the minimum material cost, has a simple and reliable structure, and can be extended to other similar applications.
[0064] In this embodiment, only an adjustment and transportation protection structure (i.e., an adjustment assembly) needs to be installed between the weighing table and the machine frame, which can not only facilitate the fine adjustment of the sensor but also protect the sensor from external forces or impact vibrations, avoiding its damage and failure.
[0065] In summary, the metal detection and weighing integrated machine of the present utility model with an adjustment and protection structure solves the problem that the weighing sensor is prone to overload and failure due to large external forces or impact vibrations generated during transportation by controlling the distance between the end face of the insulating sleeve and the end face of the conveyor frame.
[0066] The metal detection and weighing integrated machine of the present utility model with an adjustment and protection structure has a simple structure and is convenient to install. It can avoid the generation of eddy current circuits at the installation site or other parts of the weighing sensor, thereby avoiding affecting the detection performance. The metal detection and weighing integrated machine is not only convenient for adjusting the position of the weighing sensor but also beneficial to protecting the sensor during installation and transportation.
