[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] The present application is further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 6 As shown, the present application provides a feeding mechanism, including a feeding table 1 and a feeding device 2, wherein the feeding device 2 is arranged on at least one side of the feeding table 1, and the feeding table 1 is suitable for placing materials to be processed, and the feeding device 2 can transport the materials on the feeding table 1 along the feeding table 1.

[0030] The feeding device 2 includes a first feeding component 21, a second feeding component 22, a controller 23 and a driver 24. The controller 23 is suitable for making the first feeding component 21 and the second feeding component 22 approach or move away from each other in a direction perpendicular to the plane of the feeding table 1 to achieve contact or separation with the material. When the first feeding component 21 and the second feeding component 22 are in contact with the material, the material can be transported. When the first feeding component 21 and the second feeding component 22 are separated from the material, the material transportation can be stopped, thereby being able to more accurately control the movement of the material.

[0031] In some embodiments, the first feeding component 21 includes a first feeding part 211, and the second feeding component 22 includes a second feeding part 221. When the first feeding component 21 and the second feeding component 22 are close to each other, the first feeding part 211 and the second feeding part 221 are suitable for clamping materials. The driver 24 is connected to the first feeding part 211 and / or the second feeding part 221, and the driver 24 is suitable for rotating the first feeding part 211 and / or the second feeding part 221 to convey materials.

[0032] In some embodiments, the controller 23 preferably uses a cylinder, and utilizes the extension and retraction of the cylinder to achieve the first feeding component 21 and the second feeding component 22 to move closer to and farther away from each other.

[0033] In some embodiments, the first feeding portion 211 and the second feeding portion 221 are wheel-shaped structures, and materials can be transported by rotating the first feeding portion 211 and the second feeding portion 221 .

[0034] In some embodiments, the first feeding portion 211 and the second feeding portion 221 are both circumferentially provided with friction structures for contacting the material, which can increase the friction between the first feeding portion 211 and the second feeding portion 221 and the material, thereby improving the feeding stability.

[0035] In some embodiments, the friction structure can select common friction structures such as friction strips and friction bumps. Preferably, friction strips can be selected, and the friction strips are evenly spaced. The friction strips on the first feeding part 211 are parallel to the axis of the first feeding part 211, and the friction strips on the second feeding part 221 are parallel to the axis of the second feeding part 221. Such a design can reduce the compression, deformation and damage of the first feeding part 211 and the second feeding part 221 to the material.

[0036] In some embodiments, the driver 24 is suitable for causing the first feeding portion 211 and the second feeding portion 221 to rotate synchronously to convey materials, which can achieve a more stable and accurate conveying effect and is less likely to cause damage to the materials.

[0037] like Figure 2 and 3In the illustrated embodiment, the first feeding component 21 includes a first transmission portion 212, which is connected to the first feeding portion 211 in a one-to-one matching manner, and the second feeding component 22 includes a second transmission portion 222, which is connected to the second feeding portion 221 in a one-to-one matching manner. When the first feeding component 21 and the second feeding component 22 are close to each other, the first transmission portion 212 and the second transmission portion 222 are suitable for transmission matching. When the first feeding component 21 and the second feeding component 22 are away from each other, the first transmission portion 212 and the second transmission portion 222 are suitable for disconnecting the transmission matching, and the driver 24 is transmission-connected to the first transmission portion 212 or the second transmission portion 222.

[0038] In some embodiments, a coaxial transmission connection is established between the first transmission part 212 and the first feeding part 211, and when the first transmission part 212 rotates, the first feeding part 211 can rotate synchronously; a coaxial transmission connection is established between the second transmission part 222 and the second feeding part 221, and when the second feeding part 221 rotates, the second feeding part 221 can rotate synchronously.

[0039] In some embodiments, the driver 24 is connected to one of the first transmission part 212 and the second transmission part 222. The driver 24 and the first transmission part 212 or the second transmission part 222 connected to the driver 24 are fixed relative to the feeding table 1. The transmission matching direction of the first transmission part 212 and the second transmission part 222 is the same as the clamping direction of the first feeding part 211 and the second feeding part 221. When the first feeding part 211 and the second feeding part 221 clamp the material, the first transmission part 212 and the second transmission part 222 can perform transmission matching accordingly, so that the driver 24 can drive both of them at the same time.

[0040] In some embodiments, a driven wheel is coaxially disposed on the first transmission part 212 or the second transmission part 222 connected to the driver 24 , and the driver 24 can be connected to the driven wheel and drive the first transmission part 212 or the second transmission part 222 to rotate.

[0041] In some embodiments, the first transmission part 212 and the second transmission part 222 are gear structures. When the first feeding assembly 21 and the second feeding assembly 22 are close to each other, the first transmission part 212 and the second transmission part 222 can be engaged in transmission.

[0042] It is worth noting that in order to ensure the transmission meshing success of the first transmission part 212 and the second transmission part 222, before the machine is operated, the first transmission part 212 and the second transmission part 222 must be meshed first, and then the first transmission part 212 and the second transmission part 222 must be separated. After the first transmission part 212 and the second transmission part 222 are separated, the first transmission part 212 and the second transmission part 222 can stabilize their states through bearing damping and other means to avoid relative rotation between the two that destroys the meshing success when they are close.

[0043] In some embodiments, there are multiple first feeding parts 211 and second feeding parts 221, and the driver 24 is suitable for transmission connection of all first transmission parts 212 or all second transmission parts 222. Multiple first feeding parts 211 and second feeding parts 221 can improve the stability of material transportation, reduce the probability of material slippage, and improve transportation accuracy. The specific number can be set according to the difficulty of material transportation.

[0044] In some embodiments, the number of feeding devices 2 is an even number, and they are symmetrically arranged on both sides of the feeding device 2, which can improve the stability of material transportation, make the force on both sides of the material consistent, improve the transportation accuracy, and reduce the probability of material damage. The specific number can be set according to the conveying stroke of the feeding platform 1.

[0045] like Figures 1 to 2 In the illustrated embodiment, there are two feeding devices 2, which are symmetrically arranged on both sides of the feeding device 2. A plurality of first feeding parts 211 and second feeding parts 221 can be arranged on each feeding device 2. The feeding devices 2 are connected by the same transmission shaft. The driver 24 is connected to the transmission shaft and can control the rotation of the transmission shaft.

[0046] like Figure 2 In the illustrated embodiment, one of the first feeding portion 211 and the second feeding portion 221 is located below the surface of the feeding table 1, and the other is located above the surface of the feeding table 1, and both are close to the surface of the feeding table 1. The first feeding portion 211 or the second feeding portion 221 located below the surface of the feeding table 1 needs to be able to cooperate with the feeding table 1 to support and guide the material, and the first feeding portion 211 and the second feeding portion 221 will not have structural interference with the material before they approach each other.

[0047] like Figure 4 and 5In the shown embodiment, a guiding device 3 is provided on the feeding platform 1, and the guiding device 3 includes a guiding rod 31, which is arranged in parallel above the feeding platform 1 along the material conveying direction, and the spacing between the guiding rods 31 is used to accommodate the raised parts of the material. A feeding gap 13 is formed between the guiding rod 31 and the feeding platform 1, and the material can pass through the feeding gap 13. The material receiving end of the feeding platform 1 is bent away from the guiding rod 31 and has a first receiving portion 11. The material receiving end of the guiding rod 31 is bent away from the feeding platform 1 and has a second receiving portion 311. The material can smoothly enter the feeding gap 13 through the first receiving portion 11 and the second receiving portion 311, so that the guiding rod 31 and the feeding platform 1 can cooperate to guide and limit the material.

[0048] In some embodiments, the first receiving portion 11 is an arc-shaped planar structure, and the second receiving portion 311 is an arc-shaped rod-shaped structure.

[0049] like Figure 4 and 5 In the illustrated embodiment, the guiding device 3 further includes a connecting rod 32. A fixing frame 12 is provided above the feeding table 1. The connecting rod 32 is connected to the fixing frame 12. The connecting rod 32 is at least suitable for moving relative to the fixing frame 12 in a direction perpendicular to the plane of the feeding table 1 to change the size of the material passing gap 13. The height of the guiding rod 31 can be conveniently adjusted according to the thickness of the processed material. At the same time, each guiding rod 31 has a separate connecting rod 32 for adjustment, and the adjustment form is more free and diversified.

[0050] In some embodiments, the connecting rod 32 and the fixing frame 12 may be fixed by a universal threaded fastener.

[0051] like Figure 1 and 6 In the shown embodiment, a support frame 4 is arranged below the feeding table 1, and the support frame 4 includes a transverse adjustment component 41 and a longitudinal adjustment component 42. The feeding table 1 is arranged on the transverse adjustment component 41, and the transverse adjustment component 41 is arranged on the longitudinal adjustment component 42. The longitudinal adjustment component 42 includes a fixed seat 421 and a lifting rod 422. The lifting rod 422 and the fixed seat 421 are slidably connected in the vertical direction, and the top of the lifting rod 422 is connected to the transverse adjustment component 41. The lifting rods 422 are transmission-connected, and at least one lifting rod 422 is connected to a motor. The synchronous rotation of all the lifting rods 422 can be achieved through one motor, so that the feeding table 1 can be lifted and lowered synchronously as a whole and stably. The longitudinal adjustment component 42 can be used to enable the feeding table 1 to adapt to the deviation in the vertical direction between the blister machine, and the transverse adjustment component 41 and the longitudinal adjustment component 42 are compact in structure and do not occupy extra space.

[0052] In some embodiments, the lifting rod 422 and the lateral adjustment component 41 are connected in a screw connection, and the position of the lateral adjustment component 41 on the lifting rod 422 can be changed by controlling the rotation of the lifting rod 422 .

[0053] In some embodiments, the lateral adjustment component 41 includes a connecting frame 411, a sliding guide rail 412 and an adjuster 413. The connecting frame 411 and the top of the lifting rod 422 are fixedly connected. The sliding guide rail 412 is arranged on the connecting frame 411. The feeding table 1 and the sliding guide rail 412 are slidably connected. The adjuster 413 is suitable for adjusting and fixing the position of the feeding table 1 on the sliding guide rail 412. The lateral adjustment component 41 can be used to enable the feeding table 1 to adapt to the horizontal deviation between the feeding table 1 and the blister machine.

[0054] In some embodiments, the regulator 413 preferably uses a hand wheel, which is screw-connected to the bottom of the feeding platform 1 in the length direction of the sliding guide rail 412.

[0055] A food box blister machine comprises the feeding mechanism in any one of the above embodiments. When the feeding mechanism is applied to the food box blister machine, the material is generally undivided food box material to be processed.

[0056] It can be understood that applying the feeding mechanism of the present application to a food box blister machine is only a typical application. In actual use, the blister machine can also use the feeding mechanism of the present application when forming other similar products in addition to forming food boxes.
