[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The core of the utility model is to provide a material bag fixing device, which can effectively fix the material bag and prevent the material bag from shaking during the bag breaking process.

[0034] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Specifically, please refer to Figure 1-Figure 5 The utility model provides a material bag fixing device, which includes a pressing plate device 100 and a pin assembly 200.

[0036] The pressing plate device 100 includes a first driving mechanism 101 and a pressing plate 103 . The first driving mechanism 101 is used to drive the pressing plate 103 to flip.

[0037] The first driving mechanism 101 can be a cylinder, a linear motor, a hydraulic cylinder or other power equipment. The pressing plate 103 can be a flat plate or an arc plate of other shapes. The curvature and curvature position of the arc plate can be adaptively selected according to actual conditions, which will not be described in detail here.

[0038] The pin assembly 200 includes a second driving mechanism 201, a pin fixing plate 203 and a pin 205. The movable end of the second driving mechanism 201 is connected to the pin fixing plate 203. The pin 205 is installed on the pin fixing plate 203. The pin 205 is arranged on the side of the pin fixing plate 203 facing the material bag. The pin 205 is used to be inserted into the material bag.

[0039] The second driving mechanism 201 may also be a cylinder, a linear motor, a hydraulic cylinder or other power equipment. The insertion needle 205 may be a columnar structure, a conical structure or other shapes, as long as it can be smoothly inserted into the bag. The top of the insertion needle 205 may be set as a sharp point to quickly pierce the bag.

[0040] There is a fixing position for clamping the material bag between the pressing plate 103 and the pin fixing plate 203.

[0041] The first driving mechanism 101 and the second driving mechanism 201 drive the pressing plate 103 and the pin fixing plate 203 to move closer to or farther from each other, so that an area for passing and clamping the material bag is formed between the pressing plate 103 and the pin fixing plate 203, that is, the material bag fixing position. When the material bag passes through this area, the first driving mechanism 101 and the second driving mechanism 201 are controlled to drive the pressing plate 103 and the pin fixing plate 203 to move closer to each other, and the pin 205 is inserted into one side of the material bag, and the other side of the material bag is pressed by the pressing plate 103, and finally the material bag is fixed.

[0042] The utility model provides a bag fixing device, which drives the pressing plate 103 and the pin fixing plate 203 to move closer to or farther from each other through the first driving mechanism 101 and the second driving mechanism 201, so that a fixed position for passing the bag and clamping the bag is formed between the pressing plate 103 and the pin fixing plate 203. When the bag reaches the fixed position, the first driving mechanism 101 and the second driving mechanism 201 are controlled to drive the pressing plate 103 and the pin fixing plate 203 to move closer to each other, the pin 205 is inserted into one side of the bag, and the other side of the bag is pressed by the pressing plate 103, which can effectively fix the bag and prevent the bag from shaking during the bag breaking process.

[0043] In order to facilitate the rapid separation of the material bag and the material in the material bag, a jet channel for inputting gas from the outside is provided in the insertion pin 205, and a pin blowing port 204 connected to the jet channel is provided on the insertion pin 205. One end of the jet channel is connected to the outside through the pin blowing port 204, and the other end is connected to the gas storage device through a pipeline. When the insertion pin 205 is inserted into the material bag, the jet starts to be blown, and the gas in the material bag is filled to inflate the material bag, forming a gap between the material and the material, so as to facilitate the discharge of the material.

[0044] Furthermore, in order to improve the material discharge efficiency, the number of the pins 205 is multiple and arranged at intervals, thereby improving the blowing efficiency and the fixing stability. In addition, multiple pin blowing ports 204 can also be arranged on the pin 205.

[0045] In a specific embodiment, the pressure plate device 100 also includes a connecting rod device 102 and a rotating shaft. The movable end of the first driving mechanism 101 is connected to one end of the connecting rod device 102, and the other end of the connecting rod device 102 is connected to the rotating shaft. The pressure plate 103 is installed on the rotating shaft. The rotating shaft is rotatably mounted on the bracket. The first driving mechanism 101 can be flexibly set at different positions by setting the connecting rod device 102. It only needs to select a suitable connecting rod device 102, and realize the transmission of force through multiple connecting rods. The cooperation of the connecting rod device 102 and the rotating shaft can realize the conversion of the linear motion of the first driving mechanism 101 into the flipping motion of the pressure plate 103 rotating around the rotating shaft.

[0046] Specifically, a nut is welded to the tail of the connecting rod device 102 , and the first driving mechanism 101 is threadedly connected to the nut. The rotation of the connecting rod device 102 is controlled by the extension and retraction of the movable end of the first driving mechanism 101 .

[0047] In order to achieve the stability of the device, there are two first drive mechanisms 101 and two connecting rod devices 102, and the two ends of the rotating shaft are respectively connected to a first drive mechanism 101 through a connecting rod device 102. In order to reasonably plan the positions of various components, the first drive mechanism 101 is set on the side of the pressure plate 103 away from the fixed position, and the second drive mechanism 201 is set on the side of the pin fixing plate 203 close to the fixed position.

[0048] like Figure 3 As shown, the connecting rod device 102 is bilaterally symmetrical, with the first driving mechanism 101 connected to both ends, and a pressing plate 103 is fixed to the middle of the rotating shaft.

[0049] Similarly, there are two second drive mechanisms 201, one of which is installed on each side of the pin fixing plate 203. The second drive mechanism 201 can control the forward and backward movement of the pin 205. The pin fixing plate 203 is fixed to the movable end of the second drive mechanism 201 by bolts or welding.

[0050] Based on the above specific embodiment, a pin hole for inserting the pin 205 is provided on the pressing plate 103. The pin 205 corresponds to the pin hole one by one, so that the pin 205 can be inserted into the pin hole when the material package is fixed, thereby improving the stability of the material package fixation.

[0051] On the basis of the above specific embodiment, a pressing plate blowing port 105 is provided on the pressing plate 103, and the pressing plate blowing port 105 is connected to an external gas storage device. After the material bag is cut by the cutting knife, air is blown into the material bag through the pressing plate blowing port 105 on the pressing plate 103 to achieve shaking of the material bag, so that the material falls quickly. The pressing plate blowing port 105 of the pressing plate 103 and the pin blowing port 204 of the pin 205 are arranged in coordination with each other, reducing the probability of contact between the material and the material bag.

[0052] The size, quantity and position of the pressing plate blowing port 105 can be adaptively selected according to actual needs. In this case, a plurality of pressing plate blowing ports 105 can be provided, corresponding to different areas of the material bag.

[0053] The present solution further includes a bracket, and the fixed end of the first driving mechanism 101 and the fixed end of the second driving mechanism 201 are both arranged on the bracket, providing a mounting position for the first driving mechanism 101 and the second driving mechanism 201. Specifically, the fixed end of the first driving mechanism 101 is fixed to the bracket by bolts or other fasteners, and the fixed end of the second driving mechanism 201 is fixed to the bracket by bolts or other fasteners.

[0054] The bracket may be a silo shell, or other supporting components in the silo, which is not further limited herein.

[0055] The pin assembly 200 further includes a drive mechanism fixing plate 202, which is connected to the fixed end of the second drive mechanism 201, and is provided with an escape opening for passing the pin 205. The drive mechanism fixing plate 202 and the pin fixing plate 203 can be arranged in parallel, the middle of the pin 205 is movably connected to the drive mechanism fixing plate 202, and the bottom of the pin 205 is fixedly connected to the pin fixing plate 203.

[0056] When used specifically, the steps of the bag fixing process of the bag breaking machine of this scheme are as follows:

[0057] 1. In the initial state, the movable end of the first driving mechanism 101 is in a retracted state, at which time the pressure plate 103 is in a plate-upward state, and at this time the pressure plate 103 is in a horizontal or inclined state; the second driving mechanism 201 is in an extended state, at this time the pin 205 is in a state away from the pressure plate 103.

[0058] 2. The material bag enters the material bin through the feed port and reaches the material bag fixing device. At this time, the upper part of the material bag is located at the fixed position between the pressure plate device 100 and the pin assembly 200.

[0059] 3. The movable end of the first driving mechanism 101 extends forward, and the connecting rod device 102 drives the rotating shaft connected to the pressing plate 103 to start rotating under the control of the first driving mechanism 101, thereby driving the pressing plate 103 to rotate downward;

[0060] 4. When the pressing plate 103 is turned to the vertical state, the movable end of the first driving mechanism 101 stops moving;

[0061] 5. The movable end of the second driving mechanism 201 retracts backwards, driving the insertion pin 205 to approach the pressing plate 103. The insertion pin 205 passes through the insertion pin 205 hole in the material bag and the pressing plate device 100 to fix the material bag;

[0062] 6. The pressing plate 103 and the insert pin 205 start to blow, and the pressing plate blowing port 105 and the insert pin blowing port 204 blow outwards. At this time, the material bag swells and a gap is formed between the bag and the material.

[0063] 7. The cutter device in the bag breaking machine starts to work to break the bag. At this time, due to the double effect of the gas sprayed from the side of the pressure plate 103 and the gas sprayed from the pin 205, the material falls rapidly.

[0064] 8. After the material dropping is completed, the second driving mechanism 201 returns to the initial state, the insertion needle 205 is withdrawn from the material bag, and the insertion needle 205 stops the blowing action;

[0065] 9. The first driving mechanism 101 returns to the initial position. At this time, the pressing plate 103 returns to the plate-upward state driven by the connecting rod device 102, and the pressing plate 103 stops the blowing action, thereby achieving a process of fixing and breaking the material bag once;

[0066] 10. The fixing and breaking of the next material bag repeats the process of steps 1-9 above, which will not be described in detail here.

[0067] The beneficial effects of the bag fixing device provided by this solution are:

[0068] The pressure plate device 100 and the pin assembly 200 fix the material bag therebetween, ensuring that the material bag is in a fixed state when the cutting knife is cutting, and that there will be no pulling between the material bag and the cutting knife due to unstable fixation of the material bag. At the same time, the blowing ports provided on the pressure plate device 100 and the pin assembly 200 form a certain gap between the material and the outside of the material bag, thereby reducing the probability of contact between the material bag and the material and further avoiding contamination of the material.

[0069] In addition, the utility model also provides a bag breaking machine, including the bag fixing device in the above specific embodiment. Obviously, the bag breaking machine including the bag fixing device has the same beneficial effects, which will not be described in detail here.

[0070] The purpose of the utility model is to provide a bag fixing device and a bag breaking machine using the bag fixing device, so as to solve the problem of bag debris being generated during the bag breaking process due to unstable bag fixing, thereby contaminating materials, so that the bag breaking machine can be widely used in food, medicine, new energy, chemical and other industries.
