Abstract
Description
Technical Field
[0001] The present application relates to the technical field of multi-head weigher structure design, and in particular to a multi-head weigher collecting hopper structure and a multi-head weigher. Background Art
[0002] Multi-head weigher is also called computer combination weigher or electronic combination weigher. It includes multiple weighing units with independent feeding structure and discharging structure. It mainly uses the principle of permutation and combination to automatically optimize and combine the load of each weighing unit to obtain the best and closest combination to the quantitative value for packaging. At present, the collection hopper of the multi-head weigher is generally fixedly installed under the weighing hopper to collect the weighed materials.
[0003] However, the applicant discovered in the actual manufacturing process that the existing collection hopper has the phenomenon of materials sticking to the collection hopper, which will result in the weighed materials not being able to enter the next production process through the collection hopper. Taking the packaging of mushroom slices as an example, in the process of mushroom slices falling into the collection hopper through the outlet of the weighing hopper after being weighed by multiple weighing hoppers, the mushroom slices themselves contain a certain amount of moisture and the surface area of one side is large and relatively flat, which may cause the mushroom slices to stick to the collection hopper, which will cause part of the mushroom slices to stick to the collection hopper, and the weighed materials cannot all enter the next production process (for example, packaging), resulting in low production efficiency.

DETAILED DESCRIPTION
[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0033] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0034] The technical solution of the present application is described in detail below with reference to the accompanying drawings.
[0035] Example 1
[0036] like Figures 1 to 7As shown, according to the first aspect of the present application, this embodiment provides a multi-head weigher hopper structure 101, including a hopper body 1 and a pusher 2. The hopper body 1 is used to be arranged below a plurality of weighing hoppers 102 to collect the weighed materials. The pusher 2 includes a mounting ring 21, a plurality of driving devices 22 and a plurality of bearing blocks 23. The mounting ring 21 is formed into an annular structure, and the hopper body 1 is movably arranged in the mounting ring 21; a plurality of bearing blocks 23 are installed outside the hopper body 1 along the circumferential interval of the hopper body 1, and a plurality of driving devices 22 are installed on the mounting ring 21 along the circumferential interval of the hopper body 1, and a plurality of driving devices 22 are arranged one by one with a plurality of bearing blocks 23; wherein, the multi-head weigher hopper structure 101 includes a first state and a second state, in the first state, the output end of the driving device 22 and the bearing block 23 abut against each other to drive the bearing block 23 to move upward; in the second state, the output end of the driving device 22 and the bearing block 23 are separated from each other to allow the hopper body 1 to fall freely.
[0037] Through the above technical scheme, the aggregate hopper body 1 of the present application can switch between the first state and the second state under the action of the driving device 22, so that when multiple weighing hoppers 102 complete weighing and put the material into the aggregate hopper body 1, the aggregate hopper body 1 is first in the first state (that is, the aggregate hopper body 1 moves upward) and then switches to the second state (that is, the aggregate hopper body 1 falls freely under the action of gravity), so that the material in the aggregate hopper body 1 is vibrated (vibrated), which can effectively prevent the material from sticking to the aggregate hopper body 1, thereby effectively ensuring that all the materials weighed each time can enter the next production process, thereby effectively improving the production operation efficiency.
[0038] The working principle / working process of the above technical solution can be:
[0039] At the beginning of each weighing process, the drive device 22 is started, and the output end of the drive device 22 abuts against the supporting block 23 and pushes it upward. When the weighing bucket 102 completes weighing and releases the material, it can be switched to the second state, that is, the output end of the drive device 22 is separated from the supporting block 23, so that the aggregate hopper body 1 falls freely under the action of gravity, and finally falls on the output end of the drive device 22, thereby vibrating (vibrating). In this process, it is also possible to prevent the material from adhering to the inner wall of the aggregate hopper body 1, thereby ensuring that all the materials weighed each time can enter the next production process.
[0040] In the above embodiment, it is understood that the bearing block 23 can be set as an annular structure sleeved outside the collecting hopper body 1 to ensure the contact reliability between the driving device 22 and the bearing block 23. Of course, the bearing block 23 can also be set as a plurality of block structures, which is not specifically limited in this application.
[0041] In one embodiment of the present application, Figure 4 and Figure 5 As shown, the driving device 22 of the present application can be set as an electrically controlled telescopic rod, and the bottom surface of the bearing block 23 is recessed inward to form a receiving cavity 231 that matches the output end of the electrically controlled telescopic rod. In this embodiment, the electrically controlled telescopic rod has high control sensitivity and fast response speed, and can be well adapted to the weighing needs of the multi-head scale 100. At the same time, the receiving cavity 231 provided in the bearing block 23 can serve as the action space of the output end of the electrically controlled telescopic rod, which can ensure that the driving device 22 stably and reliably lifts the collecting hopper body 1.
[0042] It can be understood that, in this embodiment, the size of the accommodating cavity 231 can be slightly larger than the size of the output end of the electric-controlled telescopic rod to improve the fault tolerance.
[0043] In one embodiment of the present application, in the first state, the upward movement distance H of the driving device 22 driving the bearing block 23 satisfies: 1 cm ≤ H ≤ 5 cm. Since the upward movement distance of the driving device 22 driving the bearing block 23 is related to the vibration effect of the aggregate hopper body 1, the larger the upward movement distance, the more obvious the vibration, but the larger the upward movement distance, the easier it is to damage the driving device 22. Therefore, in this embodiment, the upward movement distance is set to 1 cm to 5 cm. This is not only conducive to ensuring the vibration effect of the aggregate hopper body 1, but also conducive to avoiding damage to the driving device 22.
[0044] When the upward distance is set to 1 cm, the aggregate hopper body 1 can have a certain vibration performance while ensuring the safest driving device 22. When the upward distance is set to 5 cm, the aggregate hopper body 1 can have a better vibration performance while effectively avoiding damage to the driving device 22.
[0045] In one embodiment of the present application, Figures 1 to 4 As shown, the bearing blocks 23 and driving devices 22 of the present application can be respectively set to four, the four bearing blocks 23 are evenly spaced along the circumference of the aggregate hopper body 1 and installed outside the aggregate hopper body 1, and the four driving devices 22 are evenly spaced along the circumference of the mounting ring 21 and installed on the mounting ring 21.
[0046] In this way, through the support block 23 and the driving device 22 arranged in this way, not only can the driving effect of the driving device 22 on the aggregate hopper body 1 be effectively guaranteed, but it is also beneficial to ensure the stability of the aggregate hopper body 1 in the first state, the second state and in the switching process between the first state and the second state.
[0047] In one embodiment of the present application, Figures 1 to 4As shown, the aggregate hopper body 1 of the present application may include a first part 11, a second part 12 and a third part 13 connected in sequence from top to bottom, the first part 11 is formed into an annular structure, and the first part 11 is used to be mounted outside a plurality of weighing hoppers 102; the second part 12 is formed into an annular structure, and the second part 12 includes a first end 121 connected to the first part 11 and a second end 122 connected to the third part 13, and in a direction from the first end 121 to the second end 122, a radial dimension of the second part 12 gradually decreases, and the third part 13 is formed into an annular structure, and a radial dimension of the third part 13 is smaller than a radial dimension of the first part 11, and the third part 13 is used to collect materials that fall into the aggregate hopper body 1.
[0048] In this way, the hopper body 1 thus configured can effectively ensure the collection effect of the materials and reduce the contact area between the materials and the inner wall of the hopper body 1 , which is beneficial to further effectively avoid the possibility of the materials adhering to the inner wall of the hopper body 1 .
[0049] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the mounting ring 21 of the present application can be sleeved outside the third part 13, and the bearing block 23 is arranged on the outer wall of the third part 13. In this way, through the mounting ring 21 arranged in this way, not only can the distance between the driving force of the driving device 22 and the center of gravity of the collecting hopper body 1 be effectively reduced, thereby facilitating the stable driving of the driving device 22 for the collecting hopper body 1, but also it is conducive to reducing the space occupied by the mounting ring 21, so that it can be well adapted to various production lines.
[0050] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the multi-head weigher hopper structure 101 of the present application may further include a limit member 3, the limit member 3 includes a limit ring 31, and the limit ring 31 is sleeved outside the first part 11 to limit the horizontal displacement of the multi-head weigher hopper structure 101 in the first state and / or the second state.
[0051] In this way, by means of the limit member 3 thus arranged, the horizontal displacement of the multi-head weigher hopper structure 101 in the first state and / or the second state can be effectively limited, thereby avoiding the deviation of the hopper body 1, which is beneficial to ensure that stable and reliable vibration can be obtained in the next weighing process.
[0052] In one embodiment of the present application, Figure 6As shown, the limiting member 3 of the present application may also include a plurality of limiting strips 32, which extend in the vertical direction, and are arranged on the inner wall of the limiting ring 31 at intervals along the circumference of the limiting ring 31, and the side of the limiting strips 32 away from the limiting ring 31 is used to abut against the outer wall of the collecting hopper body 1. In this way, the limiting strips 32 arranged in this way can more reliably limit the collecting hopper body 1 to ensure that the movement direction of the collecting hopper body 1 is only in the up and down direction.
[0053] In one embodiment of the present application, Figure 7 As shown, the side of the limiting strip 32 of the present application close to the hopper body 1 is formed into an arc surface 321, and the arc surface 321 is tangent to the side of the hopper body 1. In this way, the friction between the limiting strip 32 and the hopper body 1 can be effectively reduced, thereby reducing the influence of the limiting strip 32 on the falling process of the hopper body 1, and further, the vibration effect of the hopper body 1 caused by falling can be improved to a certain extent.
[0054] According to the second aspect of the present application, Figure 1 As shown, a multi-head weigher 100 is also provided, comprising a multi-head weigher collecting hopper structure 101 according to any technical solution of the first aspect of the present application.
[0055] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
