Detailed implementation mode

[0034] The present utility model will be further described below with reference to the accompanying drawings.

[0035] Refer to Figures 5 - 12 As shown, the food fixing mechanism of this embodiment includes a frame 1, a carrier table 2, a rolled cloth 3 and a negative pressure generating mechanism 9.

[0036] In this embodiment, the frame 1 includes a rectangular frame, side plates and a platform. The rectangular frame is welded by a plurality of square steels, and adjustable height feet are provided at the four corners at the lower end of the rectangular frame to level the frame 1 when it is placed on the ground. There are four side plates, which are respectively installed on the four sides of the rectangular frame. The platform is a plurality of flat plates fixedly connected to the upper end of the rectangular frame.

[0037] In this embodiment, the carrier table 2 is arranged on the frame 1, specifically on the front side of the upper end of the platform. The carrier table 2 has a first bearing area 22 and a groove 21 extending left and right behind the first bearing area 22. The longitudinal section of the groove 21 is arc-shaped. A plurality of air holes 23 are provided at the upper end of the carrier table 2 at the first bearing area 22.

[0038] In this embodiment, the rolled cloth 3 covers the carrier table 2. The front end of the rolled cloth 3 is fixedly connected to the front side of the carrier table 2, and the rear side of the rolled cloth 3 is connected to the frame 1. The part of the rolled cloth 3 covering the first bearing area 22 forms a second bearing area 31, and the part of the rolled cloth 3 covering the groove 21 forms a rolling part 32 with a shape adapted thereto, that is, a circular arc-shaped rolling part 32 is formed. The rolled cloth 3 is made of a breathable material, that is, air can penetrate through the rolled cloth 3.

[0039] In this embodiment, the negative pressure generating mechanism 9 is arranged on the frame 1, and the suction end of the negative pressure generating mechanism 9 is connected to a plurality of air holes 23. Specifically, the negative pressure generating mechanism 9 includes a negative pressure pump 91 and an air pipe 92 connected to the negative pressure suction end of the negative pressure pump 91, and the negative pressure pump 91 is arranged on the frame 1. The air pipe 92 is connected to a plurality of air holes 23. Specifically, a shunt cavity 24 is provided in the stage 2, and a plurality of air holes 23 are all connected to the shunt cavity 24, and the shunt cavity 24 is connected to the suction end of the negative pressure generating mechanism 9. In this way, the air pipe 92 can be connected to a plurality of air holes 23 by connecting the shunt cavity 24 between the plurality of air holes 23 and the air pipe 92.

[0040] This embodiment takes the fruit leather as an example to introduce the fixing principle process of the food fixing mechanism. In addition to fixing the fruit leather, it can also be used to fix other flaky foods, such as thousand sheets, egg rolls, etc.

[0041] Before fixing, the cloth roll 3 should be laid flat on the first bearing area 22 to form the second bearing area 31, and then the fruit leather should be laid flat on the second bearing area 31, and then the negative pressure pump 91 should be started (the negative pressure pump 91 can also be started in advance), so that the negative pressure pump 91 can suck the air in the diversion chamber 24 through the air pipe 92, so that each air hole 23 can form a negative pressure to suck the cloth roll 3 above, so as to fix the cloth roll 3 with negative pressure, keep it flat, and prevent it from loosening during the rolling operation, so as to ensure that the rolling operation can be completed smoothly. Since the cloth roll 3 is made of breathable material, each air hole 23 will also suck the fruit leather through the cloth roll 3, so that the fruit leather can be adsorbed and fixed, so that the fruit leather can be kept flat, prevent it from displacement, and can be rolled neatly to improve the wrapping quality of the fruit leather.

[0042] It is worth mentioning that, since the fruit leather is mostly rectangular before rolling, the plurality of air holes 23 of this embodiment are distributed in a rectangular array. In addition to the arrangement of this embodiment, other embodiments are also arranged in a shape corresponding to the shape of the actual food.

[0043] Furthermore, in this embodiment, a cover plate assembly groove 25 is provided at the upper end of the stage 2, which is located on the upper side of the diverter cavity 24 and communicates with the diverter cavity 24. The stage 2 also includes a cover plate 26 installed in the cover plate assembly groove 25 for closing the upper side of the diverter cavity 24. The plurality of air holes 23 are all provided on the cover plate 26. In this way, when it is necessary to clean each air hole 23, each air hole 23 can be cleaned by removing the cover plate 26, which is convenient for cleaning.

[0044] It is worth mentioning that a number of evenly distributed support blocks 27 are provided inside the diversion cavity 24, and the support blocks 27 are used to support the cover plate 26 to keep the cover plate 26 flat and prevent the cover plate 26 from bending and deforming under the action of negative pressure.

[0045] In this embodiment, the food fixing mechanism further includes a height adjusting mechanism 10, which is arranged on the frame 1 and is in transmission connection with the loading platform 2. The height adjusting mechanism 10 is used to adjust the longitudinal height of the loading platform 2. By adjusting the height of the loading platform 2, the loading platform 2 can be adapted to other mechanisms of the food rolling machine to meet different usage requirements.

[0046] Specifically, the loading platform 2 is longitudinally slidably connected to the platform of the frame 1. The height adjusting mechanism 10 includes an adjusting component 101. The adjusting component 101 includes an adjusting screw 1011, and the adjusting screw 1011 is longitudinally threadedly connected to the platform of the frame 1. The upper end of the adjusting screw 1011 abuts against the loading platform 2 to support the height adjusting mechanism 10. When the adjusting screw 1011 is rotated, the adjusting screw 1011 will move up and down relative to the frame 1 according to the rotation direction. Thus, the loading platform 2 abutting against the upper end of the adjusting screw 1011 will move up and down synchronously, so that the loading platform 2 can be adjusted.

[0047] Furthermore, the adjusting component 101 further includes an adjusting handle 1012 and a top block 1013. The adjusting handle 1012 is arranged at the lower end of the adjusting screw 1011 for the user to turn the adjusting screw 1011. The top block 1013 is arranged at the upper end of the adjusting screw 1011, and the adjusting screw 1011 abuts against the loading platform 2 through the top block 1013. The top block 1013 is used to increase the abutting area between the adjusting screw 1011 and the loading platform 2 to support the loading platform 2 more stably.

[0048] In this embodiment, there are two groups of adjusting components 101, and the two groups of adjusting components 101 are distributed at intervals front and back. In this way, the loading platform 2 can have more supporting points so that the loading platform 2 can be stably supported.

[0049] In this embodiment, the height adjusting mechanism 10 further includes a longitudinal sliding component 102. The loading platform 2 and the frame 1 are longitudinally slidably connected through the longitudinal sliding component 102. Specifically, the longitudinal sliding component 102 includes a sliding column 1021 and a sliding cylinder 1022 sleeved outside the sliding column 1021. The sliding column 1021 is fixedly connected to the loading platform 2, and the sliding cylinder 1022 is fixedly connected to the frame 1.

[0050] In this embodiment, there are four groups of longitudinal sliding components 102. The four groups of adjusting components 101 are distributed at intervals in a rectangle, so as to stabilize the up and down sliding movement of the loading platform 2.

[0051] Refer to Figures 1 - 4 As shown, the food rolling machine of this embodiment includes the aforementioned food fixing mechanism and further includes a rolling and pushing mechanism 5.

[0052] In this embodiment, the pushing mechanism 5 of the rolling part is arranged on the frame 1, which includes a pushing part located at the rear side of the rolling part 32 and on the lower surface of the fabric roll 3, and a second driving mechanism 52 for driving the pushing part to move back and forth. Under the forward drive of the second driving mechanism 52, the pushing part pushes the rolling part 32 to move forward, so as to roll the food placed on the second bearing area 31 forward.

[0053] In this embodiment, the pushing part is configured as a second rod 51 whose length is distributed in the left - right direction. The second driving mechanism 52 is configured to include a first mounting seat 521, a sliding seat 522, a threaded rod 523, a sliding rod 524, a driving motor 525, and a push - pull rod 526. There are two first mounting seats 521, and the two first mounting seats 521 are arranged on the frame 1 at intervals in the front - rear direction, that is, fixed on the platform. The threaded rod 523 is rotatably connected to the two first mounting seats 521. The driving motor 525 is used to drive the threaded rod 523 to rotate. Specifically, the driving motor 525 is fixedly connected to the rear first mounting seat 521, and its output end is connected with a driving gear. The corresponding end of the threaded rod 523 is connected with a driven gear, and a transmission belt is connected between the driving gear and the driven gear. When the driving motor 525 drives the driving gear to rotate, the driving gear can drive the driven gear to rotate through the transmission belt, so that the driven gear can drive the threaded rod 523 to rotate. There are two sliding rods 524, and both ends of the sliding rod 524 are connected to the two first mounting seats 521 respectively. The two sliding rods 524 are respectively located on the left and right sides of the threaded rod 523. The sliding seat 522 is slidably connected to the two sliding rods 524 and is threadedly connected to the threaded rod 523. There are two push - pull rods 526, and the two push - pull rods 526 are respectively located on the left and right sides of the threaded rod 523. The rear ends of the two push - pull rods 526 are both connected to the sliding seat 522, and the front ends of the two push - pull rods 526 are respectively connected to the left and right ends of the second rod 51. Thus, when the threaded rod 523 rotates, the threaded rod 523 can cooperate with the sliding rod 524 to drive the sliding seat 522 to move back and forth, so that the sliding seat 522 can drive the second rod 51 to move back and forth through the push - pull rod 526.

[0054] It is worth mentioning that in addition to the implementation method of this embodiment, in other embodiments, a second cylinder, a second hydraulic cylinder, or a second electric push - rod and other devices can also be considered for driving the second driving mechanism 52.

[0055] In this embodiment, both ends of the second rod 51 are rotatably connected to the front ends of the two push - pull rods 526 so as to be able to rotate around its own axis. Thus, when the fabric roll 3 rubs against the second rod 51, the second rod 51 can rotate with the friction to reduce wear, so as to protect the fabric roll 3.

[0056] This embodiment takes the rolling of fruit pastilles as an example to introduce the rolling process of this food rolling mechanism. In addition to rolling fruit pastilles, it can also be used for rolling other thin - sheet foods, such as dried bean curd sheets, egg rolls, etc.

[0057] Before rolling, the second rod 51 should be located at the rear side of the groove 21 so that the rolled part 32 formed in the groove 21 is at the front side of the second rod 51.

[0058] When rolling, the rolling cloth 3 should be spread first. When spreading, the rolling cloth 3 is laid flat on the carrier table 2 to form a flat second bearing area 31 in the first bearing area 22. Then, the rear part of the rolling cloth 3 is pressed into the groove 21 to form a semi-circular rolled part 32. The opening of the rolled part 32 will face upward. During the process of pressing the rolling cloth 3 into the groove 21 to form the rolled part 32, it is necessary to ensure that the rolled part 32 and the second bearing area 31 are smooth and continuous without wrinkles as much as possible. Preferably, the rolling cloth 3 is made of a material with a certain toughness to avoid wrinkles. During this process, the negative pressure pump 91 can be activated to adsorb and fix the second bearing area 31.

[0059] After the rolling cloth 3 is spread, the fruit leather can be placed. When placing, the fruit leather is laid flat on the second bearing area 31 of the rolling cloth 3. After being laid flat, it will be adsorbed and fixed by the negative pressure generating mechanism 9.

[0060] After the fruit leather is placed, the specific rolling can be carried out. During the specific rolling, the second driving mechanism 52 is controlled to drive the second rod 51 to move forward, so that when the second rod 51 moves forward, it pushes the shape of the rolled part 32 to be transmitted forward. When the rolled part 32 is transmitted to the fruit leather, the fruit leather will be rolled up following the shape of the rolled part 32. As the rolled part 32 continues to be transmitted forward, the fruit leather can be wrapped together from the back to the front. After the second rod 51 pushes the rolled part 32 to be transmitted forward and completely wraps the fruit leather, the second driving mechanism 52 is controlled to drive the second rod 51 to reset backward. At this time, the rolled fruit leather can be taken off.

[0061] The height adjustment mechanism 10 introduced above can adjust the distance between the carrier table 2 and the second rod 51 by adjusting the height of the carrier table 2, so as to change the inner diameter of the rolled part 32 to meet different rolling requirements.

[0062] In this embodiment, the food rolling mechanism further includes a rolled part reset mechanism 6. The rolled part reset mechanism 6 includes a third rod 61 arranged above the rolling cloth 3 and corresponding to the position of the groove 21 and a third driving mechanism 62 for driving the third rod 61 to enter and exit the groove 21. When the third rod 61 enters the groove 21, it will press the corresponding part of the rolling cloth 3 into the groove 21 to restore the shape of the rolled part 32.

[0063] Specifically, the third driving mechanism 62 includes a driver 621, a second mounting seat 622, a third mounting seat 623, a first swing rod 624, and a second swing rod 625. The second mounting seat 622 and the third mounting seat 623 are arranged on the frame 1 at intervals in the front and rear directions. One end of the first swing rod 624 is rotatably connected to the second mounting seat 622, the other end of the first swing rod 624 is connected to the third rod 61, one end of the second swing rod 625 is fixedly connected to the first swing rod 624, and the other end is hinged to the output end of the driver 621. The mounting end of the driver 621 is hinged to the third mounting seat 623. When the output end of the driver 621 expands and contracts, it will drive the second swing rod 625 to cooperate with the first swing rod 624 to drive the third rod 61 to rotate into and out of the groove 21. In this way, the part of the rolling cloth 3 pressed into the groove 21 by the third rod 61 can form a rolling part 32. By resetting the rolling part 32 through the rolling part reset mechanism 6, the manual operation steps can be reduced, so as to further improve the automation degree of the food rolling mechanism.

[0064] It is worth mentioning that an assembly groove is provided on the lower side of the third rod 61 in this embodiment, and this assembly groove is used to assemble a wear-resistant plastic pressing rod (not shown in the figure). Since the wear-resistant plastic pressing rod is softer in texture than stainless steel, pressing the rolling cloth 3 with the wear-resistant plastic pressing rod can play a protective role for the rolling cloth 3, so as to extend the service life of the rolling cloth 3.

[0065] The driver 621 in this embodiment is a third air cylinder. In addition to the implementation manner of this embodiment, in other embodiments, a third hydraulic cylinder or a third electric push rod and other devices can also be considered for driving.

[0066] The food rolling machine in this embodiment includes the aforementioned food rolling mechanism, and also includes a control mechanism 7. The control mechanism 7 is electrically connected to each driving mechanism and can control the actions of each driving mechanism. Specifically, the control mechanism 7 includes a controller, a start panel, and an operation panel that are electrically connected to the controller. In this embodiment, the controller is integrated on the frame 1, and the controller can be implemented by using an existing PLC controller. The start panel and the operation panel are both arranged on the frame. The start panel is at least provided with control buttons that can control the power supply, start, stop, and other actions of the entire food rolling machine. The control panel is integrated with a display screen that can display the operating parameters of the food rolling machine and several setting buttons that can set the parameters of the entire food rolling machine.

[0067] It is worth mentioning that the food rolling machine in this embodiment is also provided with a position sensor, which is arranged above the sliding seat 522. When the driving motor 525 drives the sliding seat 522 to cooperate with the push-pull rod 526 to drive the second rod 51 to reset, the driving motor 525 uses the signal when the position sensor detects the sliding seat 522 as the stop working signal. Such a design can ensure that the second rod 51 can be reset to the same position every time after rolling is completed, avoiding cumulative errors and abnormal movement strokes of the second rod 51.

[0068] In this embodiment, the food rolling machine further comprises a cover 8 disposed on the frame 1 and covering the outer sides of the cloth rolling and releasing mechanism 4, the rolling part pushing mechanism 5 and the rolling part resetting mechanism 6. The cover 8 can beautify the appearance of the entire food rolling machine and protect each mechanism at the same time.

[0069] In this embodiment, the food rolling machine also includes a loading rack 81 and a discharging rack 82 arranged on the front side of the frame 1. The loading rack 81 is located above the discharging rack 82 and is used to carry the food to be rolled so that workers can quickly pick up the food for loading. The rear side of the loading rack 81 has a discharge channel 811 for the rolled food to fall from the loading platform 2 to the discharging rack 82. After the food is rolled, the rolled food will form an inertia of moving forward due to the push of the rolling part 32. In this way, after the food is completely rolled, it will roll forward until it falls from the loading platform 2. The fallen food roll will fall into the discharging rack 82 through the discharge channel 811, so that automatic unloading and automatic collection can be completed.

[0070] To sum up, the utility model discloses a food fixing mechanism and a food rolling machine thereof, which can replace manual rolling of thin-sheet foods. During rolling, the food can be fixed by negative pressure to keep the rolling cloth and the food flat and avoid displacement, so that the food can be rolled neatly, thereby improving the rolling quality of the fruit leather. Compared with manual rolling, it has higher rolling efficiency and can meet large-scale production needs. In addition, it can reduce labor costs, improve economic benefits, and facilitate market promotion and use.

[0071] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
