DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.
[0029] like Figures 1 to 5 As shown, a food filling and packaging machine of the present invention comprises two sets of coiling and clamping structures which are arranged in sequence and opposite to each other, and the coiling and clamping structures are used to clamp and fix the position of the bag opening of the woven bag;
[0030] The winding and clamping structure comprises a sleeve 1 and a core shaft 2 which is rotatably inserted into the sleeve 1. A plurality of notches are provided on the outer wall of the sleeve 1. A first clamping plate 3 is provided on the outer wall of the core shaft 2 which is exposed at the notch position. A plurality of second clamping plates 4 are provided on the outer wall of the sleeve 1. The first clamping plates 3 and the second clamping plates 4 are used in conjunction with each other to clamp the bag opening of the woven bag.
[0031] When the first clamping plate 3 and the second clamping plate 4 clamp the bag opening of the woven bag, the sleeve 1 and the core shaft 2 rotate synchronously, so that the woven bag is rolled on the sleeve 1.
[0032] In detail, the sleeve 1 and the core shaft 2 are coaxial, and the sleeve 1 and the core shaft 2 are horizontal. The sleeve 1 can rotate on the core shaft 2, so as to adjust the position relationship between the first clamp 3 and the second clamp 4. The notch on the sleeve 1 is used to provide an installation position for the first clamp 3, and the notch limits the movable range of the first clamp 3, so as to limit the relative rotation angle of the sleeve 1 and the core shaft 2. The first clamp 3 and the second clamp 4 correspond in position and are used to clamp and fix the edge position of the woven bag from the inside and outside of the woven bag. The two sets of winding and clamping structures are divided into front and back to roll and clamp the front and back sides of the bag mouth of the woven bag.
[0033] When in use, the first clamping plate 3 is vertically downward, and the woven bag is sleeved on the outer sides of the multiple first clamping plates 3 on the two sets of winding and clamping structures, and the two sleeves 1 are rotated in opposite directions synchronously, so that the sleeve 1 rotates on the core shaft 2, and the second clamping plate 4 on the sleeve 1 rotates and squeezes the bag mouth of the woven bag on the first clamping plate 3, thereby realizing the clamping of the woven bag, and then the sleeve 1 and the core shaft 2 are rotated synchronously, and the rotation direction of the sleeve 1 remains unchanged, that is, the sleeve 1 and the core shaft 2 rotate outward, so that the first clamping plate 3 and the second clamping plate 4 will drive the bag mouth position of the woven bag to be rolled and wrapped on the outer wall of the sleeve 1, and the two sets of winding and clamping structures synchronously perform flanging and winding processing on the bag mouth position of the woven bag, thereby realizing effective fixation of the woven bag, in this way, the clamping method and the rolling friction method can be used to improve the supporting effect of the woven bag, and the material can automatically fall into the woven bag through the bag mouth opened between the two sets of winding and clamping structures, thereby realizing the packaging of food materials.
[0034] The mechanized coiling and clamping structure automatically completes the clamping and fixing of the woven bag, reduces manual participation, improves the automation level of the overall packaging process, and replaces manual operation with automation, reduces the situation where workers need to maintain a fixed posture for a long time, reduces the intensity of physical labor, and helps to improve the working environment. Since the packaging machine can automatically complete a series of packaging actions, such as clamping, rolling, etc., it can significantly shorten the packaging time of a single woven bag, thereby improving the overall production efficiency; by adopting the clamping and rolling methods, the fixing effect of the woven bag can be greatly improved, avoiding the phenomenon of woven bags slipping and tipping during filling, and improving the packaging stability; in summary, this new type of food filling and packaging machine can effectively solve the problems existing in the traditional woven bag packaging process, and bring more efficient, more stable and more economical packaging solutions.
[0035] Furthermore, the end of the core shaft 2 extends out of the sleeve 1 , and the end of the core shaft 2 is provided with a rack 5 and a gear 6 for use together, the rack 5 is vertical, and the gear 6 is installed on the core shaft 2 .
[0036] In detail, the rack 5 is fixed in position and the gear 6 can roll on the rack 5. When the first clamp 3 and the second clamp 4 on the winding structure complete the clamping work on the bag mouth, the sleeve 1 continues to rotate and drives the core shaft 2 to rotate through the second clamp 4 and the first clamp 3. The core shaft 2 drives the gear 6 to roll on the rack 5, so that the sleeve 1 and the core shaft 2 drive the bag mouth to move downward while completing the winding work. This can ensure that the height position of the woven bag remains unchanged, and avoid the woven bag from moving up and leaving the platform at its bottom when the sleeve 1 and the core shaft 2 are directly wound at the moving height.
[0037] Furthermore, a first vertical groove 7 is formed on the side wall of the rack 5 , a slide seat 8 is slidably disposed in the first vertical groove 7 , and the end of the core shaft 2 is rotatably mounted on the slide seat 8 .
[0038] In detail, by providing the first vertical groove 7 and the slide seat 8, the core shaft 2 and the rack 5 can be easily connected and fixed to ensure that the gear 6 always rolls on the rack 5.
[0039] Furthermore, a first spring 9 for connecting the slide seat 8 and the rack 5 is provided in the first vertical groove 7, and a retaining edge 10 for limiting the gear 6 is provided at both the upper and lower ends of the rack 5;
[0040] A first worm 12 is vertically rotatably provided on the rack 5 at one side of the winding and clamping structure, and a first worm wheel 11 is meshed with the first worm 12 . The first worm wheel 11 is fixed on the sleeve 1 .
[0041] In detail, the first spring 9 provides an upward elastic thrust for the slide seat 8, and the two ribs 10 can limit the position of the gear 6 on the rack 5. In the natural state, the gear 6 abuts against the rib 10 on the upper side of the rack 5. When the sleeve 1 rotates, it can drive the second clamping plate 4 to approach the first clamping plate 3 and clamp the bag mouth position of the woven bag. Then, the sleeve 1 continues to rotate, and the sleeve 1 will drive the core shaft 2 to rotate through the second clamping plate 4 and the first clamping plate 3, so that the gear 6 rolls on the rack 5, and the first spring 9 undergoes elastic deformation. In this way, the dual working effects of clamping and rolling can be achieved by simply applying power to the sleeve 1.
[0042] The first worm 12 can drive the first worm wheel 11 to rotate, thereby providing power for the movement of the sleeve 1 and the core shaft 2. Since the sleeve 1 and the core shaft 2 move in the vertical direction, the first worm wheel 11 can roll on the first worm 12, and the first worm wheel 11 and the first worm 12 maintain a transmission state.
[0043] Furthermore, a support plate 13 is fixed on the side wall of each rack 5;
[0044] An outer frame 14 is arranged outside the two sets of winding clamp structures, and a plurality of transverse grooves 15 are opened on the inner wall of the outer frame 14. The support plate 13 is slidably installed in the transverse grooves 15, and the sliding direction of the transverse grooves 15 is parallel to the connecting direction of the two sets of winding clamp structures.
[0045] In detail, the outer frame 14 can provide support for the two sets of winding and clamping structures through the support plate 13. The external filling pipe 23 is located between the two sets of winding and clamping structures and is used to fill materials into the woven bag. When the two sets of winding and clamping structures complete the work of fixing the bag mouth position of the woven bag, the two sets of winding and clamping structures approach each other and squeeze the woven bag onto the filling pipe 23, thereby utilizing the winding and clamping structure and the filling pipe 23 to cooperate to achieve a further fixing effect on the woven bag.
[0046] Furthermore, a second worm wheel 16 is provided on the first worm 12, and a second worm 17 and a motor 18 are provided on the support plate 13. The second worm 17 is rotatably mounted on the support plate 13, and the motor 18 is driven by the second worm 17. The second worm 17 is meshedly connected with the two second worm wheels 16, and the axis of the second worm 17 is parallel to the moving direction of the transverse groove 15.
[0047] In detail, the motor 18 can drive the two second worm wheels 16 to rotate through the second worm 17, and the two second worm wheels 16 synchronously drive the two first worm wheels 12 to rotate, thereby providing power for the two sets of winding clamp structures at the same time. When the winding clamp structure moves, the second worm wheel 16 and the second worm 17 remain in meshing state.
[0048] Furthermore, two second vertical grooves 19 are relatively opened on the inner wall of the support plate 13, and a movable seat 20 is slidably arranged in the two second vertical grooves 19. The movable seat 20 is located between the two support plates 13 on the same side of the two sets of winding clamp structures, and the movable seat 20 is connected to the support plate 13 through a connecting rod 21.
[0049] In detail, the connecting rod 21 is inclined, and the two ends of the connecting rod 21 are rotatably connected to the support plate 13 and the movable seat 20 respectively, so that when the support plate 13 on one set of winding clamp structures moves, it can drive the movable seat 20 to move vertically through a connecting rod 21, and the movable seat 20 will drive the support plate 13 on the other set of winding clamp structures to move through another connecting rod 21, thereby realizing the synchronous relative movement of the two sets of winding clamp structures.
[0050] Furthermore, the movable seat 20 is connected to the outer frame 14 via a second spring 22;
[0051] The second worm 17 is formed by connecting two independent worms with opposite spiral directions.
[0052] In detail, the second spring 22 can provide an elastic thrust for the movable seat 20, so that in the natural state, the movable seat 20 is located at one end in the second vertical groove 19, so that when the motor 18 drives the two second worm wheels 16 to rotate through the second worm gear 17, the support plate 13 cannot move, and when the gear 6 moves to the position of the retaining edge 10 on the lower side of the rack 5, the gear 6 cannot move in the vertical direction. At this time, since the two independent worm gears on the second worm gear 17 continue to provide power to the two second worm gears 16, the two second worm gears 16 will approach each other. At this time, the movable seat 20 overcomes the elastic force of the second spring 22 and slides, thereby using a single motor 18 to realize the synchronous vertical movement and relative movement of the two sets of winding structures, and the two second worm gears 16 cooperate with the two independent worm gears.
[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
