Description

Technical Field

[0001] The utility model belongs to the technical field of grain counting machines, in particular to a grain counting machine for food packaging. Background Art

[0002] With the continuous progress of society, more and more mechanical equipment is involved in production activities. For example, in the process of food production and packaging, a grain counting machine is often needed. As the name suggests, a grain counting machine can accurately and quantitatively discharge granular food, thereby facilitating subsequent quantitative bagging or bottling.

[0003] When an existing grain counting machine is in use, it discharges food grains according to a specified number. In order to further facilitate bagging or bottling, it generally guides and concentrates the food through a necking piece. However, in actual use, some granular foods are relatively fragile. When the food is discharged and falls into the necking piece, the food will collide with the inner wall of the necking piece. In this process, some food is easily broken, thereby affecting the quality of the final product. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a food packaging and counting machine, which solves the problem that food is easily broken due to falling and impact during the discharge process of the existing counting machine, affecting the quality of the final product.

[0005] To achieve the above object, the present invention provides the following technical solution: a food packaging counting machine, comprising a counting machine body, an internal thread ring installed at the bottom of the counting machine body, and a shrinkage concentrating piece provided on the inner side of the internal thread ring;

[0006] The top of the necking concentrator is provided with an annular groove, and a mounting ring is provided inside the annular groove. A fitting airbag is installed at the bottom of the mounting ring, and positioning grooves are evenly provided at the bottom of the annular groove.

[0007] A first limiting groove is formed on the inner side wall of the internal threaded ring. A gas accommodating chamber is reserved on a side of the mounting ring near the first limiting groove, and the gas accommodating chamber is in communication with the mating airbag. An elastic mechanism is provided inside the gas accommodating chamber for limiting the rotation of the concentrating member.

[0008] A special-shaped hole is reserved at the bottom of one side of the outer wall of the shrinkage concentrator, and an externally threaded air inlet pipe is connected to the bottom of the outer wall of the matching airbag near the special-shaped hole, and the externally threaded air inlet pipe passes through the special-shaped hole. An air inlet one-way valve is installed inside the externally threaded air inlet pipe, and a fixing nut is sleeved on the outer side of the end of the externally threaded air inlet pipe away from the matching airbag;

[0009] A second limiting groove is reserved at the top of the fixing nut close to one end of the externally threaded air inlet pipe, and a limiting mechanism for limiting the rotation of the fixing nut is provided on the externally threaded air inlet pipe.

[0010] As a further solution of the present invention: the central axis of the necking concentrator coincides with the central axis of the internal thread ring, and the necking concentrator and the internal thread ring are threadedly connected.

[0011] As a further solution of the present invention: positioning rods are evenly installed on the bottom of the mounting ring, and the positioning rods extend to the inside of the positioning groove.

[0012] As a further solution of the present invention: the elastic mechanism includes a first piston limiter, the first piston limiter is arranged inside the gas accommodating chamber, and the first piston limiter passes through the shrinkage concentrator and extends to the inside of the first limit groove, and a first spring is connected between the first piston limiter and the shrinkage concentrator.

[0013] As a further solution of the present invention: the externally threaded air inlet pipe and the necked concentrator form a relative sliding structure, and the externally threaded air inlet pipe and the fixing nut are threadedly connected.

[0014] As a further solution of the present invention: the limiting mechanism includes an L-shaped tube, the L-shaped tube is connected to the top of the outer wall of the externally threaded air intake pipe, a second piston limiting component is provided inside the L-shaped tube, and the second piston limiting component passes through the necking concentrator and extends to the inside of the second limiting groove, and a second spring is connected between the second piston limiting component and the L-shaped tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. A fitting airbag is provided on the mounting ring, so that when in use, the fitting airbag can be filled with air. When food particles fall through the counting machine body into the shrinkage concentrator, the fitting airbag can replace the shrinkage concentrator to collide with the food particles and reduce damage to the food through its own elastic deformation, thereby preventing the food from colliding and breaking in this link and affecting the quality of the final product.

[0017] 2. The necking concentrator is threadedly connected to the internal thread ring, the mounting ring is set inside the annular groove, and the external thread air inlet pipe is threadedly connected to the fixing nut. When necessary, the staff can quickly and conveniently disassemble the necking concentrator from the main body of the counting machine, and can further disassemble the necking concentrator and the matching airbag, which is convenient for the staff to carry out maintenance and other work.

[0018] 3. An elastic mechanism for limiting the rotation of the necking concentrator is provided in the gas containing chamber, and a limiting mechanism for limiting the rotation of the fixing nut is provided on the externally threaded air inlet pipe. When the fitted airbag is filled with air, the connection between the necking concentrator and the internally threaded ring, and the connection between the externally threaded air inlet pipe and the necking concentrator can be further stabilized, thereby ensuring the stability of the assembly and avoiding loosening during subsequent use.

[0027] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0028] like Figure 1-Figure 7 As shown, the utility model provides a technical solution:

[0029] Example 1

[0030] A food packaging counting machine includes a counting machine body 1. The counting machine body 1 is the same as the existing similar counting equipment and will not be described in detail here.

[0031] An internally threaded ring 2 is mounted on the bottom of the counting machine body 1, and a converging member 3 is disposed on the inner side of the internally threaded ring 2. An electromagnetic valve can be disposed at the opening at the bottom of the converging member 3. After the counting machine body 1 feeds a fixed amount of food particles into the converging member 3, the food particles are temporarily stored in the converging member 3. When the packaging bag or bottle is aligned with the bottom opening of the converging member 3, the electromagnetic valve opens, and the food particles enter the packaging bag or bottle.

[0032] The central axis of the necking centralizer 3 coincides with the central axis of the internal thread ring 2, and the necking centralizer 3 and the internal thread ring 2 are threadedly connected. When the necking centralizer 3 is not restricted in rotation, the necking centralizer 3 can be directly rotated and removed from the internal thread ring 2 by rotating the necking centralizer 3, which is convenient and quick.

[0033] An annular groove 4 is provided on the top of the necking concentrator 3, and a mounting ring 5 is provided inside the annular groove 4. A fitting airbag 6 is installed at the bottom of the mounting ring 5. Positioning grooves 7 are evenly provided at the bottom of the annular groove 4. The mounting ring 5 fits with the annular groove 4. The fitting airbag 6 is fully filled with air and its shape fits with the internal shape of the necking concentrator 3. In subsequent use, the fitting airbag 6 can replace the necking concentrator 3 to collide with falling food particles. The elastic deformation of the fitting airbag 6 can reduce the impact damage to the food particles, thereby preventing the food from being easily broken in this link and affecting the quality of the final product.

[0034] Positioning rods 8 are evenly installed on the bottom of the mounting ring 5, and the positioning rods 8 extend into the interior of the positioning grooves 7, so that when the fitting airbag 6 is assembled, the positioning rods 8 can be inserted into the corresponding positioning grooves 7 to achieve a quick positioning task;

[0035] A special-shaped hole 13 is reserved at the bottom of the outer wall of the shrinkage concentrator 3. An externally threaded air inlet pipe 14 is connected to the bottom of the outer wall of the matching airbag 6 near the special-shaped hole 13, and the externally threaded air inlet pipe 14 passes through the special-shaped hole 13. An air inlet one-way valve 15 is installed inside the externally threaded air inlet pipe 14. A fixing nut 16 is provided on the outer side of the externally threaded air inlet pipe 14 away from the end of the matching airbag 6. The externally threaded air inlet pipe 14 and the shrinkage concentrator 3 form a relative sliding structure, and the externally threaded air inlet pipe 14 and the fixing nut 16 are threadedly connected, so that during assembly, since the inside of the matching airbag 6 is not filled with air at this time, the matching airbag 6 is completely in a soft state, so the externally threaded air intake pipe 14 can be passed through the circular part corresponding to the special-shaped hole 13, and then the externally threaded air intake pipe 14 is basically fixed on the shrinkage concentrator 3 by rotating the fixing nut 16 onto the externally threaded air intake pipe 14, and then the key point positioning of the fitting airbag 6 is completed in cooperation with the mounting ring 5, so that the fitting airbag 6 can be fully maintained in the position that fits with the inside of the shrinkage concentrator 3 when it is subsequently filled with air. At the same time, when air is filled into the fitting airbag 6, the air intake one-way valve 15 can be pushed open by the top pipe adapted to the externally threaded air intake pipe 14 and air can be filled into the fitting airbag 6.

[0036] Example 2

[0037] Based on the above embodiment 1, a first limiting groove 9 is provided on the inner side wall of the internal threaded ring 2, a gas accommodating chamber 10 is reserved on the side of the mounting ring 5 close to the first limiting groove 9, and the gas accommodating chamber 10 is communicated with the fitting airbag 6, and an elastic mechanism for limiting the rotation of the shrinkage concentrator 3 is provided inside the gas accommodating chamber 10, and the elastic mechanism includes a first piston limiting member 11, the first piston limiting member 11 is provided inside the gas accommodating chamber 10, and the first piston limiting member 11 passes through the shrinkage concentrator 3 and extends to the inside of the first limiting groove 9, the first piston A first spring 12 is connected between the limiting member 11 and the necking concentrator 3. The first piston limiting member 11 is slidably connected to the mounting ring 5. Under normal conditions, the first spring 12 drives the first piston limiting member 11 to be located inside the gas accommodating chamber 10, without affecting the assembly of the conforming airbag 6. When the conforming airbag 6 is filled with air, the air pressure inside the conforming airbag 6 drives the first piston limiting member 11 to slide and insert into the first limiting groove 9, thereby restricting the rotation between the necking concentrator 3 and the internal threaded ring 2, thereby fully ensuring the stability of the assembly.

[0038] A second limiting groove 17 is reserved at the top of the fixing nut 16 near one end of the externally threaded air intake pipe 14, and a limiting mechanism is provided on the externally threaded air intake pipe 14 for limiting the rotation of the fixing nut 16. The limiting mechanism includes an L-shaped tube 18, which is connected to the top of the outer wall of the externally threaded air intake pipe 14. A second piston limiting member 19 is provided inside the L-shaped tube 18, and the second piston limiting member 19 passes through the shrinkage concentrator 3 and extends to the inside of the second limiting groove 17. A second spring 20 is connected between the second piston limiting member 19 and the L-shaped tube 18. Similarly to the above, the second piston limiting member 19 and the L-shaped tube 18 are slidingly connected. Under normal conditions, the second piston limiting member 19 is located inside the L-shaped tube 18. After the fitting airbag 6 is filled with air, the second piston limiting member 19 is inserted into the inside of the second limiting groove 17, thereby limiting the rotation between the fixing nut 16 and the externally threaded air intake pipe 14, thereby ensuring the stability of the assembly.

[0039] The working principle of the present invention is as follows: the device is powered by an external power supply. The counting machine body 1 pushes a fixed amount of food particles into the top of the inner part of the necked concentrator 3. The food particles then fall into the inner part of the necked concentrator 3 and, under the restriction of the shape of the necked concentrator 3, are concentrated through the discharge port at the bottom of the necked concentrator 3 and finally fall into the packaging bag or packaging bottle below the necked concentrator 3. During the above process, the conforming airbag 6 will replace the inner wall of the necked concentrator 3 to directly collide with the falling food particles. The elastic deformation of the conforming airbag 6 itself can reduce the rigid collision with the food particles, thereby preventing the food particles from being easily broken and affecting the quality of the final product.

[0040] When it is necessary to disassemble and maintain the shrinkage concentrator 3 and the fitting airbag 6, use a thimble to insert the inside of the externally threaded air inlet pipe 14 to push open the air inlet one-way valve 15, so that the air in the fitting airbag 6 is discharged through the externally threaded air inlet pipe 14. As mentioned above, at this time, the first piston limiter 11 slides into the inside of the gas containing chamber 10, releasing the rotation restriction of the shrinkage concentrator 3 and the internally threaded ring 2, and the second piston limiter 19 slides into the inside of the L-shaped tube 18, releasing the rotation restriction of the fixing nut 16 and the externally threaded air inlet pipe 14, unscrew the shrinkage concentrator 3 from the internally threaded ring 2, unscrew the fixing nut 16 from the externally threaded air inlet pipe 14, and take the fitting airbag 6 out of the shrinkage concentrator 3, so that the disassembly task can be completed conveniently and quickly.

[0041] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
