Description

Technical Field

[0001] The present invention relates to the technical field of food processing and transportation, and specifically relates to a transportation device for food processing. Background Art

[0002] Food processing refers to the processing activities of directly using agricultural, forestry, animal husbandry, and fishery products as raw materials, such as cereal milling, feed processing, vegetable oil and sugar processing, slaughtering and meat processing, aquatic product processing, and the processing of foods such as vegetables, fruits, and nuts. In order to improve the efficiency of food processing, from raw materials to cleaning, processing, and finally packaging, multiple sets of transportation devices are used for transmission to achieve automatic transportation between various processes, ensure the automation of food processing links, reduce manual participation, and improve food safety.

[0003] Most common transportation devices use the rotation of a drive shaft or the transmission of a conveyor belt to transport food, but the above transportation methods have defects in specific food processing procedures; specifically, in the food packaging link, especially when packing food into some packaging boxes or cans with relatively small openings, the food scattered at different positions on the conveyor belt will not accurately fall into the packaging carrier. At this time, an external guiding structure is required to achieve the precise transportation of food, which increases the equipment cost. Moreover, when dealing with foods of different specifications and sizes, different guiding structures need to be replaced, and the use process is relatively cumbersome. In view of this, we provide a transportation device for food processing. Summary of the Invention

[0004] Aiming at the above-mentioned disadvantages of the prior art, the present invention provides a transportation device for food processing, which can effectively solve the problems that most existing transportation devices use the rotation of a drive shaft or the transmission of a conveyor belt to transport food, but the above transportation methods have defects in specific food processing procedures; specifically, in the food packaging link, especially when packing food into some packaging boxes or cans with relatively small openings, the food scattered at different positions on the conveyor belt will not accurately fall into the packaging carrier. At this time, an external guiding structure is required to achieve the precise transportation of food, which increases the equipment cost. Moreover, when dealing with foods of different specifications and sizes, different guiding structures need to be replaced, and the use process is relatively cumbersome.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0006] The present invention provides a transportation device for food processing, including a transportation frame. An inlet frame is provided on the upper side at one end of the transportation frame. A plurality of transportation rollers are evenly and rotatably connected at the middle position of the transportation frame. The transportation rollers are frustum structures with the diameter gradually increasing from the middle to both ends, and a rubber ring is provided on the outer wall of the transportation rollers, and there is a cavity between the rubber ring and the transportation rollers;

[0007] At one end of the conveying frame, a driving shaft fixedly connected to the output end of an external motor is provided. Driving gears are arranged at both ends of the driving shaft. The driving gears are meshed with chains arranged on both sides of the conveying frame, and the chains are meshed with driven gears fixedly connected to the end parts of the conveying rollers. Moreover, cams are symmetrically and fixedly installed on the driving shaft;

[0008] It further includes a moving plate elastically connected to the conveying frame. A bladder is arranged between the moving plate and the conveying frame. The bladder is communicated with the external air through a one-way intake pipe, and the bladder is communicated with the cavity inside the conveying roller through a connecting pipe. A lapping block is fixedly installed on the outer wall of the upper end of the moving plate. When the driving shaft rotates, the cam will contact and squeeze the lapping block, causing the gas in the bladder to enter the cavity, so as to realize the adjustment of the food conveying trajectory.

[0009] Furthermore, hoses are fixedly installed at both ends of the conveying roller. A plurality of hoses are all communicated with the connecting pipe. A chamber is arranged in the middle of the conveying roller. A plurality of through holes are uniformly formed in an annular structure on the inner wall of the chamber; and the diameters of both ends of the conveying roller are larger, and the diameter of the position where the chamber is opened in the middle is smaller; the cavity is communicated with the chamber through a one-way connection hole. When the bladder is squeezed, the gas inside it will flow through the cavity into the chamber and overflow from the through holes.

[0010] Furthermore, the rubber ring is a frustum structure with a hollow middle and is wrapped on the outer wall of the conveying roller; a plurality of metal sheets are uniformly arranged on the outer wall of the rubber ring in an annular structure.

[0011] Furthermore, it further includes a moving frame slidably connected to the conveying frame. The moving frame is elastically connected to the conveying frame through a spring. A second inclined block is fixedly installed on the moving frame. A first inclined block is also fixedly installed on the moving plate. The first inclined block and the second inclined block are slidably matched; two lapping plates are fixedly installed on the moving frame. A plurality of electromagnetic sheets are linearly and equidistantly arranged on the lapping plates. It further includes a pressure switch arranged on the surface of the second inclined block. When the first inclined block contacts the second inclined block, it will cause the electromagnetic sheets to be energized and magnetically adsorb the metal sheets arranged on the outer wall of the rubber ring.

[0012] Furthermore, it further includes two piston rods fixedly installed on the outer wall of the moving frame, and a piston tube fixedly connected to the conveying frame. The piston rods and the piston tube are slidably matched. The end of the piston tube is communicated with a bent tube; it further includes clamping members symmetrically and movably connected to the conveying frame. A plurality of clamping plates are linearly and equidistantly fixedly connected to the upper end of the clamping members. A sponge layer is arranged on the outer wall of the clamping plates; and the bent tube is a rigid plastic tube. The outlet end of the bent tube is lapped with the outer wall of the clamping member. When the gas in the piston tube overflows, it will act on the outer wall of the clamping member and cause the two clamping members to approach each other.

[0013] Further, it further includes a cross frame fixedly installed on the outer wall of the lower end of the conveying frame. Two clamping members are slidably connected to the cross frame. A plurality of columnar protrusions are evenly arranged on the cross frame. When the clamping members are displaced on the cross frame, the clamping plates will adjust the conveying trajectory of the food on the conveying rollers.

[0014] Further, when the conveying rollers are not rotating, in the vertical direction, the positions of the plurality of clamping plates correspond to the positions of the plurality of electromagnetic sheets, and each clamping plate is located between the middle parts of two adjacent conveying rollers.

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0034] The present invention will be further described below with reference to the embodiments

[0035] Embodiment

[0036] Refer to the attached Figure 1-8As shown in the figure, a conveying device for food processing includes a conveying frame 100. At the upper side of one end of the conveying frame 100, a feeding frame 110 is provided. At the middle position of the conveying frame 100, a plurality of conveying rollers 300 are evenly rotatably connected. The conveying rollers 300 are frustum structures with the diameter gradually increasing from the middle to both ends. And a rubber ring 330 is provided on the outer wall of the conveying roller 300, and there is a cavity 301 between the rubber ring 330 and the conveying roller 300. At one end of the conveying frame 100, a driving shaft 210 fixedly connected to the output end of an external motor is provided. Active gears 212 are provided at both ends of the driving shaft 210. The active gears 212 are meshed with a chain 200 provided on both sides of the conveying frame 100, and the chain 200 is meshed with a driven gear 320 fixedly connected to the end of the conveying roller 300. Specifically, in this application, the mentioned conveying device is mainly used for transporting fruit foods, such as spherical foods like tomatoes and Chinese dates during the automated food processing process. First, when the conveying device mentioned in this application is in operation, it can effectively ensure that during the conveying process of spherical foods, their conveying trajectories are relatively fixed;

[0037] To better understand this solution, in this embodiment, tomatoes are used as the conveying object for the scheme description;

[0038] In this application, the conveying roller 300 is a frustum structure with the diameter gradually increasing from the middle to both ends. Flexible hoses 310 are fixedly installed at both ends of the conveying roller 300. A plurality of flexible hoses 310 are all in communication with a connecting pipe 102. A chamber 302 is provided in the middle of the conveying roller 300. A plurality of through holes 303 are evenly formed in a ring structure on the inner wall of the chamber 302; and the diameters of both ends of the conveying roller 300 are larger, and the diameter of the position where the chamber 302 is opened in the middle is smaller. Specifically, during the actual conveying process, when the food to be conveyed falls into the conveying device from the feeding frame 110 in an irregular trajectory for conveying between different processing modules in the food processing process, since the set conveying roller 300 has a smaller diameter in the middle and larger diameters on both sides, it can be understood that the middle of the conveying roller 300 is recessed. During the actual conveying process, tomatoes are circular structures. When the middle of the conveying roller 300 is recessed, during subsequent conveying, under the action of its own gravity, it will automatically move closer to the middle of the conveying roller 300. That is, in the corresponding conveying link, tomatoes will move from the large-diameter position of the conveying roller 300 towards the small-diameter position in the middle. After conveying for a period of time, a plurality of tomatoes originally irregularly distributed on the conveying roller 300 will tend to be conveyed in the middle of the conveying roller 300.

[0039] As mentioned above, during the actual conveying process, the tomatoes will move closer to the middle of the conveying roller 300 for conveying. To improve the conveying efficiency, the more tomatoes are placed on the conveying roller 300 per unit time, the greater the conveying efficiency. Therefore, in the actual use process, it will happen that multiple tomatoes will contact and stack in the middle concave part of the conveying roller 300, but they will be arranged in two or even multiple irregular rows. At the conveying end, it cannot accurately ensure the dropping position of the tomatoes. Therefore, in this application, cams 211 are symmetrically and fixedly installed on the driving shaft 210; it also includes a moving plate 120 elastically connected to the conveying frame 100. A bladder 130 is arranged between the moving plate 120 and the conveying frame 100. The bladder 130 is in communication with the external air through a one-way intake pipe 101, and the bladder 130 is in communication with the cavity 301 inside the conveying roller 300 through a connecting pipe 102. A lapping block 121 is fixedly installed on the outer wall of the upper end of the moving plate 120. When the driving shaft 210 rotates, the cam 211 will contact and squeeze the bladder 130 with the lapping block 121, so that the gas in the bladder 130 enters the cavity 301, realizing the adjustment of the food conveying trajectory;

[0040] Specifically, in this application, the power for conveying comes from the driving shaft 210 rotatably connected to the conveying frame 100 and fixedly connected to the output end of an external motor. Driving gears 212 are sleeved on both ends of the driving shaft 210. The driving gears 212 will drive the arranged chain 200 to rotate. And considering the meshing relationship between the chain 200 and the driven gear 320 on the outer wall of the conveying roller 300, it will drive the arranged conveying roller 300 to rotate. When the driving shaft 210 rotates, the cam 211 fixedly connected to the driving shaft 210 will intermittently contact the lapping block 121 on the moving plate 120 and drive the moving plate 120 to move downward. It will squeeze the bladder 130, and the gas in the bladder 130 will overflow and enter the cavity 301 inside. When the cavity 301 is filled with gas, the rubber ring 330 will expand, and then adjust the position of the tomatoes located on the upper side of the conveying roller 300, so that they can stably be in the middle concave position of the conveying roller 300.

[0041] Furthermore, to ensure that the tomatoes can be stably conveyed, when the gas enters the cavity 301, considering the relationship that the cavity 301 and the chamber 302 are in communication through a one-way connection hole, when the bladder 130 is squeezed, the gas inside it will flow through the cavity 301 into the chamber 302 and overflow from the through hole 303. When the gas overflows from the through hole 303, it will blow towards the position of the tomatoes. Cooperating with the expanded rubber ring 330, it is more convenient to adjust the posture of the tomatoes in the conveying state;

[0042] As an implementation manner, for example, in the cleaning process of the outer surface of tomatoes, the corresponding nozzle can be arranged at the lower side of the conveying frame 100 and spray water between the middle parts of two adjacent conveying rollers 300. The water will act on the surface of the tomatoes. Through the above method, the posture of the tomatoes can be adjusted frequently and multiple times to ensure the comprehensiveness of cleaning, guarantee the cleaning efficiency, and at the same time ensure that the tomatoes can be stably conveyed after cleaning is completed.

[0043] Furthermore, the rubber ring 330 is a frustum structure with a hollow middle and is wrapped around the outer wall of the conveying roller 300; a plurality of metal sheets 331 are uniformly arranged on the outer wall of the rubber ring 330 in a ring structure. It further includes a moving frame 500 slidably connected to the conveying frame 100. The moving frame 500 is elastically connected to the conveying frame 100 through a spring 540. A second inclined block 510 is fixedly installed on the moving frame 500. A first inclined block 122 is also fixedly installed on the moving plate 120. The first inclined block 122 and the second inclined block 510 are slidably matched; two overlapping plates 520 are fixedly installed on the moving frame 500. A plurality of electromagnetic sheets 521 are linearly arranged at equal intervals on the overlapping plates 520. It further includes a pressure switch arranged on the surface of the second inclined block 510. When the first inclined block 122 contacts the second inclined block 510, it will cause the electromagnetic sheets 521 to be energized and magnetically adsorb the metal sheets 331 arranged on the outer wall of the rubber ring 330. Specifically, during the actual conveying process, when the driving shaft 210 rotates, the cam 211 will intermittently drive the arranged moving plate 120 to reciprocate vertically. The first inclined block 122 is fixedly connected to the moving plate 120. Considering its sliding fit relationship with the second inclined block 510, it will cause the moving frame 500 fixedly connected to the second inclined block 510 to move along the conveying direction. At this time, the pressure switch arranged on the outer wall of the second inclined block 510 will be squeezed, thereby causing the electromagnetic sheets 521 to be energized and realizing the magnetic adsorption of the metal sheets 331, causing the rubber ring 330 to deform, and further adjusting the posture of the tomatoes on the surface of the rubber ring 330. From two aspects, on the one hand, regarding the subsequent conveying trajectory of the tomatoes, as mentioned above, in order to ensure the conveying efficiency, a relatively large number of tomatoes will fall on the conveying roller 300 per unit time. Considering the characteristics that the diameters of both ends of the conveying roller 300 are large and the diameter of the middle part is small, they will gather at the concave part in the middle of the conveying roller 300. Through this method, the posture of the tomatoes in the conveying process will be further adjusted, so as to ensure that the tomatoes can be stably conveyed to a specific position in the subsequent processing process, such as the filling process, or the cleaning and disinfection process, etc.

[0044] Furthermore, as mentioned above, when the conveying roller 300 in the present application conveys tomatoes, it will adjust the posture of the tomatoes. On the one hand, it ensures the determination of the final conveying trajectory. At the same time, in the cleaning process and other aspects, the efficiency of the cleaning and conveying process can also be ensured by continuously adjusting the posture of the tomatoes. However, ultimately, it is necessary to accurately ensure the determination of the conveying trajectory. Therefore, in the present application, it also includes two piston rods 530 fixedly installed on the outer wall of the moving frame 500, and a piston tube 531 fixedly connected to the conveying frame 100. The piston rod 530 is slidably engaged with the piston tube 531. The end of the piston tube 531 is communicated with a bent tube 532; it also includes a clamping member 400 symmetrically and movably connected to the conveying frame 100. The upper end of the clamping member 400 is linearly and equidistantly fixedly connected with a plurality of clamping plates 410. A sponge layer is provided on the outer wall of the clamping plate 410; and the bent tube 532 is a rigid plastic tube. The outlet end of the bent tube 532 is overlapped with the outer wall of the clamping member 400. When the gas in the piston tube 531 overflows, it will act on the outer wall of the clamping member 400 and cause the two clamping members 400 to approach each other. It also includes a cross frame 103 fixedly installed on the outer wall of the lower end of the conveying frame 100. The two clamping members 400 are slidably connected to the cross frame 103. A plurality of columnar protrusions 104 are evenly arranged on the cross frame 103. When the clamping member 400 displaces on the cross frame 103, the clamping plate 410 will adjust the conveying trajectory of the food on the conveying roller 300 to ensure that the subsequent tomatoes can be accurately conveyed, facilitate accurate dropping at a fixed position, and facilitate subsequent packaging and other processes;

[0045] Specifically, when the conveying device is actually in use, when the moving frame 500 adjusts its position along the conveying direction, in cooperation with the fixed connection relationship between the moving frame 500 and the piston rod 530, the piston rod 530 will slide in the piston tube 531, and the gas inside it will overflow from the outlet end of the provided bent tube 532 and act on the outer wall of the clamping member 400, thereby causing the clamping member 400 to slide on the cross frame 103. And when the two provided clamping members 400 approach each other, they will gradually contact and squeeze the tomatoes on the conveying roller 300, thereby further limiting the conveying trajectory of the tomatoes;

[0046] As an implementation method, by setting a distance sensor on the inner end surface of the clamping plate 410, by measuring the distance between two clamping plates 410 in a corresponding relationship, the accuracy of the conveying trajectory of the tomatoes is determined, and the clamping plate 410 will also contact the outer wall of the tomatoes, thereby playing a certain auxiliary role to ensure the stability of the tomato conveying trajectory. In order to make the clamping plate 410 better reset, elastic members can be provided in the middle of the two clamping plates 410 to ensure its stable reset.

[0047] It should be noted that in the present application, when the conveying roller 300 is not rotating, in the vertical direction, the positions of the plurality of clamping plates 410 correspond to the positions of the plurality of electromagnetic sheets 521, and each clamping plate 410 is located between the middle parts of two adjacent conveying rollers 300. When the conveying roller 300 rotates, the corresponding moving frame 500 will also adjust its position when the first inclined block 122 contacts the second inclined block 510, so that the electromagnetic sheet 521 can generate a magnetic adsorption force with the metal sheet 331 provided on the outer wall of the rubber ring 330, forcing the rubber ring 330 to deform, so as to achieve a stable adjustment of the tomato posture.

[0048] As another implementation manner, the conveying device mentioned in this solution can also be used in the screening process during the food processing link. Specifically, the conveying roller 300 has a frustum structure with a gradually increasing diameter from the middle to both ends. Since the diameters of both ends of the conveying roller 300 are larger and the diameter of the position where the chamber 302 is opened in the middle is smaller, in the middle position perpendicular to the conveying direction, which can be understood as the position where the chamber 302 is located, the gap between two adjacent conveying rollers 300 gradually increases from both ends to the middle. During the process of continuously adjusting the tomato posture in the conveying process mentioned above, the smaller tomatoes will be screened and fall to the lower side position of the conveying frame 100 to achieve the screening effect. Therefore, the conveying device mentioned in the present application can be applied to multiple links in food processing and has strong applicability.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
