Description

Technical Field

[0001] This application relates to the field of packing technology, for example, to a packing machine. Background Technology

[0002] A case packer is a device that loads unpackaged or small-packaged products into transport packaging. Its working principle is to pack products into boxes in a certain quantity according to a certain arrangement.

[0003] Existing case packing machines mostly use material handling and suction or material handling, pushing and suction methods for packing. This adds detection points such as material handling failure points, pushing failure points, and suction failure points during the packing process. Products will pause briefly at these failure points, which adds many obstacles to production continuity and equipment stability.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] Combination Figure 1 and Figure 2 As shown, this embodiment of the disclosure provides a case packing machine. The case packing machine includes a frame 1 and two case packing devices. The frame 1 is a square frame formed by twelve connecting rods 11, and crossbeams 12 are respectively provided on two opposite sides of the frame 1. The bottoms of the two case packing devices are respectively connected to the two crossbeams 12, and their tops are respectively connected to the corresponding connecting rods 11 above them for fixation. The two case packing devices have the same structure, both including a three-axis drive mechanism 2 and a receiving mechanism 6. The three-axis drive mechanism 2 is drively connected to the receiving mechanism 6 to drive the receiving mechanism 6 to complete the process of receiving materials and packing them.

[0030] The product conveying device 7 is located on one side of the frame 1 and uses a belt conveyor to transport the products 8. The empty box conveying device 9 is located at the bottom of the frame 1 and uses roller conveyor, belt conveyor, or other methods to transport the empty boxes 10.

[0031] Combination Figure 3 As shown, a three-axis drive mechanism 2 drives the corresponding receiving mechanism 6 to the output side of the product conveying device 7, and the bottom of the receiving mechanism 6 is higher than the product conveying device 7, which serves as the initial position of the receiving mechanism 6 (for clarity). Figures 3 to 6 (Only one set of packaging equipment is shown in the image). Meanwhile, the receiving port 67 of the receiving mechanism 6 corresponds to the output side of the product conveying device 7. A photoelectric sensor is installed on the output side of the product conveying device 7 to detect the number of products injected into the receiving mechanism 6. Based on the vertical dimensions of the products and the size of the material stacking space of the receiving mechanism 6, the number of products that the receiving mechanism 6 can receive is preset by the host computer, and the downward movement speed of the receiving mechanism 6 is set according to the conveying speed of the product conveying device 7 and the number of products received. The receiving mechanism 6 moves down one material level for each product received. When the receiving mechanism 6 moves down to the first position, the product stack is exactly full.

[0032] After the product conveying device 7 is in operation, such as Figure 4 As shown, the three-axis drive mechanism 2 drives the corresponding receiving mechanism 6 to gradually move downwards at a set downward speed. The product, driven by the belt, is injected into the receiving mechanism 6 and continuously stacks upwards within it as the receiving mechanism 6 moves downwards. When the receiving mechanism 6 reaches the first position, it stops moving downwards. Then, the three-axis drive mechanism 2 drives the receiving mechanism 6 to retract horizontally to the second position, so that the receiving mechanism 6 moves above the empty box. Next, it drives the receiving mechanism 6 to rotate to the third position, so that the receiving port of the receiving mechanism 6 faces the empty box below. Figure 5 As shown. It should be noted that if the receiving mechanism 6 rotates to a low position and interferes with the empty box, it can be driven to move upwards while simultaneously rotating, so that after reaching the third position, the receiving mechanism 6 maintains a certain distance from the top of the empty box. Then, as... Figure 6 As shown, the receiving mechanism 6 is driven downwards to the fourth position so that it extends into the empty box. Thus, the three-axis drive mechanism 2 drives the corresponding receiving mechanism 6 to gradually move downwards along a preset trajectory from the output side of the product conveying device 7, causing the products to stack within the receiving mechanism 6, retract horizontally, and rotate so that the material inlet of the receiving mechanism 6 aligns with the empty box and extends into it, completing the process from receiving to packing. Finally, the receiving mechanism 6 unloads. Then, the three-axis drive mechanism 2 drives the empty (unloaded) receiving mechanism 6 to quickly move upwards to the fifth position so that the lowest position of the receiving mechanism 6 reaches the height of its initial position. Afterwards, the receiving mechanism 6 is driven to rotate and extend horizontally, so that it returns to its initial position, as shown. Figure 4 As shown, prepare to receive materials again.

[0033] While one receiving mechanism 6 operates along the aforementioned trajectory, the other receiving mechanism 6 follows closely behind, operating along the same trajectory. Furthermore, after one receiving mechanism 6 completes unloading, the corresponding three-axis drive mechanism 2 drives it to first move upwards to the fifth position, then rotates and extends horizontally, returning it to its initial position. This allows the movement of the other receiving mechanism 6 along the preset trajectory to be avoided during the return of one receiving mechanism 6 to its initial position. In this way, the two receiving mechanisms 6 continuously and alternately complete the receiving and packing processes in a cyclical manner.

[0034] The case packing machine provided in this embodiment provides a frame 1 for mounting two case packing devices. The two case packing devices are connected to opposite sides of the frame 1. Each case packing device includes a three-axis drive mechanism 2 and a receiving mechanism 6 connected by a transmission link. The three-axis drive mechanism 2 drives the corresponding receiving mechanism 6 to gradually move downwards from its initial position on the output side of the product conveying device 7, causing the products to stack, retract horizontally, and rotate so that the receiving port 67 of the receiving mechanism 6 corresponds to an empty case 10 and extends into the empty case, completing the process from receiving to packing. The empty receiving mechanism 6, having completed unloading, is then driven back to its initial position, avoiding another receiving mechanism 6 during the return process. In this way, the case packing machine omits the material handling and ejection processes. By driving the receiving mechanism 6 through the three-axis drive mechanism 2, the two receiving mechanisms 6 can continuously and alternately complete receiving and packing, improving the continuity and stability of production.

[0035] Optionally, combined Figures 7 to 9 As shown, the three-axis drive mechanism 2 includes: a first linear drive mechanism 3, a rotary drive mechanism 4, and a second linear drive mechanism 5. The first linear drive mechanism 3 is vertically connected to one side of the frame 1 and can transmit power along a vertical plane. The rotary drive mechanism 4 can rotate 360° and is connected to the transmission part of the first linear drive mechanism 3, thus moving vertically (up and down) under the drive of the first linear drive mechanism 3. The second linear drive mechanism 5 is connected to the transmission part of the rotary drive mechanism 4, thus rotating between the horizontal and vertical planes under the drive of the rotary drive mechanism 4. The second linear drive mechanism 5 can transmit power linearly, and the receiving mechanism 6 is connected to the transmission part of the second linear drive mechanism 5 to move linearly under the drive of the second linear drive mechanism 5.

[0036] The initial state of the second linear drive mechanism 5 is horizontal, meaning it is horizontal when the receiving mechanism 6 receives material. During the operation of the receiving mechanism 6, the first linear drive mechanism 3 operates first, driving the receiving mechanism 6 to gradually move downwards to the first position on the output side of the product conveying device. Then, the second linear drive mechanism 5 operates, driving the receiving mechanism 6 to retract horizontally to the second position. Then, the rotary drive mechanism 4 operates, driving the receiving mechanism 6 to rotate 90° clockwise to the third position (at which point the second linear drive mechanism 5 is vertical). It should be noted that if the receiving mechanism 6 needs to be moved upwards while rotating, then the rotary drive mechanism 4 and the second linear drive mechanism 5 operate simultaneously, or the rotary drive mechanism 4 and the first linear drive mechanism 3 operate simultaneously, or the rotary drive mechanism 4, the first linear drive mechanism 3, and the second linear drive mechanism 5 operate simultaneously, driving the receiving mechanism 6 upwards through the first linear drive mechanism 3 and / or the second linear drive mechanism 5. The linear travel of the first linear drive mechanism 3 is greater than that of the second linear drive mechanism 5. Therefore, the linear drive mechanism to be operated can be selected based on the required upward movement distance. If the required upward movement distance is small, the operation of the second linear drive mechanism 5 can meet the upward movement distance. If the required upward movement distance is large, the first linear drive mechanism 3 can meet the upward movement distance. If the required upward movement distance is even larger, the combination of the first linear drive mechanism 3 and the second linear drive mechanism 5 can meet the upward movement distance. Afterward, the second linear drive mechanism 5 operates to drive the receiving mechanism 6 to move downward to the fourth position. It is understood that here, the operation of the second linear drive mechanism 5 and / or the first linear drive mechanism 3 can also be selected based on the required downward movement distance. The operation of the second linear drive mechanism 5 is preferred.

[0037] After the receiving mechanism 6 finishes unloading, the first linear drive mechanism 3 operates to drive the receiving mechanism 6 to move upward to the fifth position. Since the upward distance is relatively large, the first linear drive mechanism 3 is selected to operate here. Then the rotary drive mechanism 4 and the second linear drive mechanism 5 operate to drive the receiving mechanism 6 to rotate 90° in the opposite direction (at this time, the second linear drive mechanism 5 is in a horizontal state) and extend horizontally to the initial position.

[0038] In this way, through the cooperation of the first linear drive mechanism 3, the rotary drive mechanism 4 and the second linear drive mechanism 5, the corresponding receiving mechanism 6 is driven to complete the entire process from receiving materials, packing them into boxes to returning them.

[0039] As mentioned earlier, when one receiving mechanism gradually moves down to receive material, the other receiving mechanism should also follow suit and gradually move down to prepare for receiving material, thus achieving the goal of continuous material receiving by the two receiving mechanisms 6. At this time, the receiving ports 67 of the two receiving mechanisms are located on the same vertical plane. In this way, the two receiving mechanisms 6 can form continuous material receiving without interfering with each other.

[0040] Optionally, the first linear drive mechanism 3 includes: a first bracket 31, a first motor 32, and a belt drive structure 33. The first bracket 31 is a long, rectangular frame with its length along the vertical direction, and is vertically connected to one side of the frame 1. The first bracket 31 includes two longer rectangular second side plates 311 and four shorter rectangular baffles 312. The two second side plates 311 are arranged opposite each other, with their bottom ends connected to the corresponding crossbeams 12 and their top ends connected to the corresponding connecting rods 11 located above them. The two baffles 312 are connected between the bottoms of the two second side plates 311 to form a circumferentially enclosed bottom mounting position together with the two second side plates 311. The other two baffles 312 are connected between the tops of the two second side plates 311 to form a circumferentially enclosed top mounting position together with the two second side plates 311. The first motor 32 is mounted at the bottom, with its housing mounted on a bottom baffle 312. The power output shaft of the first motor 32 is mounted on another bottom baffle 312 via bearings. The belt drive structure 33 includes a drive pulley 331, a driven pulley 332, and a drive belt 333. The drive pulley 331 is keyed onto the power output shaft of the first motor 32. The driven pulley 332 is mounted at the top via a connecting shaft and is rotatably fitted onto the outside of the connecting shaft. The annular drive belt 333 is fitted over the drive pulley 331 and the driven pulley 332. Optionally, the drive belt 333 is a synchronous belt. The rotary drive mechanism 4 is connected to one side of the drive belt 333. Thus, the first motor 32 drives the drive pulley 331 to rotate, thereby driving the drive belt 333 to run. As the drive belt 333 moves vertically, the rotary drive mechanism 4 drives the receiving mechanism 6 to move vertically.

[0041] Optionally, the first linear drive mechanism 3 further includes a first slide rail 34 and a first slider 35. The first slide rail 34 is vertically disposed on the inner wall of the first bracket 31. Specifically, there are two first slide rails 34, each vertically disposed on the inner wall of one of the two second side plates 311, and each first slide rail 34 corresponds to one of the two sides of the transmission belt 333. The first slider 35 is connected to the outer wall of the rotary drive mechanism 4. Specifically, there are two first sliders 35, each connected to one of the two opposite outer walls of the rotary drive mechanism 4, thus making each first slider 35 correspond to one of the two first slide rails 34. Each first slider 35 has a first groove on the side facing the corresponding first slide rail 34, and each first slide rail 34 is slidably embedded in the groove of the corresponding first slider 35. In this way, the cooperation of the first slide rail 34 and the first slider 35 guides the movement of the rotary drive mechanism 4, making the rotary drive mechanism 4 more stable as it moves with the transmission belt 333.

[0042] Optionally, the rotary drive mechanism 4 includes a second bracket 41 and a second motor 42. The second bracket 41, serving as the outer wall of the rotary drive mechanism 4, is rectangular in shape. A transmission belt 333 passes through the inner frame of the second bracket 41, and the inner side of one sidewall of the second bracket 41 is connected to one side of the transmission belt 333. Simultaneously, first sliders 35 are respectively provided on the outer side of this sidewall and the outer side of the opposite sidewall. The second motor 42 is connected to the second bracket 41, and the power output shaft of the second motor 42 is connected to a connecting part 43. The connecting part 43 is disc-shaped and connected to the outer wall of the second linear drive mechanism 5. Optionally, see [link to documentation]. Figure 10 The power output shaft of the second motor 42 is connected to the connecting part 43 via a transmission shaft 44 to extend the power output shaft. The transmission shaft 44 is keyed onto the power output shaft of the second motor 42.

[0043] In this way, the transmission belt 333 can drive the second motor 42 to move vertically via the second bracket 41, and then drive the receiving mechanism 6 to move vertically via the second linear drive mechanism 5. The power output shaft of the second motor 42 drives the connecting part to rotate, which in turn drives the second linear drive mechanism 5 and the receiving mechanism 6 to rotate.

[0044] Optionally, the second bracket 41 includes two first side plates 411 and two first end plates 412. The two first side plates 411 and the two first end plates 412 are arranged in a square cylindrical structure. As mentioned above, the first bracket 31 is the supporting part of the first linear drive mechanism 3, and the transmission belt 333 is one of the transmission parts of the first linear drive mechanism 3. The two first side plates 411 are in the left-right direction (relative to...) Figure 7 The two first end plates 412 are set on the front and rear directions (relative to the front and rear directions). Figure 7The second motor 42 is mounted on the outer side of the two first side plates 411. A first slider 35 is provided on the outer side of each of the two first side plates 411, and the inner side of one of the first side plates 411 is connected to one side of the transmission belt 333. A first end plate 412 has a first mounting hole, and the other first end plate 412 has a second mounting hole, with the two mounting holes coaxially opposite each other. The housing of the second motor 42 is installed in the first mounting hole, and a bearing is installed in the second mounting hole. The power output shaft of the second motor 42 passes through the bearing and can rotate relative to the bearing, thus fixing the second motor 42 without affecting its power output. If the power output shaft of the second motor 42 is equipped with a transmission shaft 44, the transmission shaft 44 is rotatably mounted through the bearing. A connecting part 43 is connected to the outer wall of the second linear drive mechanism 5. The end of the power output shaft of the second motor 42 or the end of the transmission shaft 44 extends beyond the first end plate 412 and is connected to the connecting part 43. The rotational force of the second motor 42 is output through the connecting part 43, thereby driving the second linear drive mechanism 5 to rotate. The surface area of ​​the connecting part 43 is larger than the surface area of ​​the end of the power output shaft of the second motor 42 or the surface area of ​​the end of the transmission shaft 44, which can reduce stress when transmitting force.

[0045] Optionally, the second linear drive mechanism 5 includes: an electric guide rail 51, a second slide rail 52, and a second slider 53. The electric guide rail 51 can be in the form of a ball screw guide rail, a synchronous belt guide rail, or a rack and pinion guide rail. It should be noted that the electric guide rail 51 is existing technology and will not be described in detail here. The connecting part 43 serves as one of the transmission parts of the rotary drive mechanism 4. One outer wall of the electric guide rail 51 is connected to the connecting part 43, and the other outer wall has a second slide rail 52 arranged along its length. The transmission part of the electric guide rail 51, such as a transmission belt, is connected to the second slider 53. A second groove is provided on one side of the second slider 53, and the second slide rail 52 is slidably embedded in the second groove. Simultaneously, the receiving mechanism 6 is connected to the second slider 53. Thus, the electric guide rail 51 can drive the receiving mechanism 6 to move linearly. Meanwhile, the cooperation between the second slide rail 52 and the second slider 53 guides the movement of the receiving mechanism 6, thereby making the movement of the receiving mechanism 6 more stable.

[0046] Optionally, the second linear drive mechanism 5 further includes a first connecting plate 54. The first connecting plate 54 is a rectangular plate, and its length direction is arranged along the length direction of the electric guide rail 51, and the two are connected. The connecting part 43 is connected to the first connecting plate 54. In this way, there are more connection points between the electric guide rail 51 and the connecting part 43, making the connection more stable.

[0047] Optionally, the receiving mechanism 6 includes a connecting arm 61 and a receiving bin 62. The first end of the connecting arm 61 is connected to the transmission part of the second linear drive mechanism 5, i.e., to the transmission part of the electric guide rail 51 via the second slider 53. The second end of the connecting arm 61 is connected to the receiving bin 62. The receiving bin 62 is provided with a receiving port. (This is in conjunction with the preceding text and...) Figures 1 to 12 It is known that the three-axis drive mechanism 2 cannot drive the receiving bin 62 to extend or retract along the product injection direction A. Therefore, the connecting arm 61 is a bent part, which can keep the receiving port at a preset distance from the output side of the product conveying device, so that the receiving port is closer to the output side and can catch the product.

[0048] Optionally, combined Figures 11 to 12 As shown, the receiving bin 62 includes: a negative pressure bin 63, a negative pressure pipe 64, a baffle 65, and multiple sponge strips 66. The negative pressure bin 63 is a cylindrical body with two end faces, one of which is an open end and the other is a closed end. The closed end of the negative pressure bin 63 is provided with a negative pressure pipe 64 that communicates with the interior of the negative pressure bin 63. The baffle 65 is a cylindrical body with two end faces, one of which is an open end and the other is a closed end. The baffle 65 also has a receiving port 67 on its circumference for receiving products. The closed end of the baffle 65 and its circumferential wall together form a material stacking space. For example, if the closed end of the baffle 65 is quadrilateral, then the side of the circumferential wall of the baffle 65 is connected to three sides of the quadrilateral, and the remaining side is not connected to the circumferential wall, and the circumferential wall is not closed. Therefore, the circumference of the baffle 65 is open, and it can serve as the receiving port 67. The closed end of the enclosure 65 covers and connects to the open end of the negative pressure chamber 63. At the same time, the closed end of the enclosure 65 is provided with a plurality of first through holes 631, and each first through hole 631 is connected to the interior of the negative pressure chamber 63.

[0049] Multiple sponge strips 66 are spaced apart and arranged side-by-side at the closed end of the enclosure 65, and each sponge strip 66 is located within the material stacking space. Optionally, the sponge strips 66 are glued to the closed end of the enclosure 65. Multiple first through holes 631 are located at the intervals between two adjacent sponge strips 66, that is, the location of the first through holes 631 avoids the location of the sponge strips 66. When the receiving bin 62 receives products, the receiving bin 62 is located on one side of the conveyor belt, and the receiving port 67 corresponds to the output end of the conveyor belt. The products are injected into the receiving bin 62 through the conveyor belt. At the same time, the receiving bin 62 moves downward under the drive of the drive device, thereby causing the products to continuously stack upward within the material stacking space. The length direction of each sponge strip 66 is arranged along the direction of material stacking, that is, the length direction of the sponge strip is vertical.

[0050] In use, air is drawn out through the negative pressure pipe 64 to create negative pressure in the negative pressure chamber 63. When the product is injected into the receiving chamber 62, one side of the product is adsorbed onto the surface of the sponge strip 66 under the action of negative pressure, thereby achieving product gripping. When the negative pressure pipe 64 stops drawing air, the negative pressure in the negative pressure chamber 63 is eliminated, thereby achieving unloading.

[0051] The receiving chamber 62 provided in this embodiment is used. The negative pressure chamber 63 is a cylindrical body with one end open and the other end closed, and a negative pressure pipe 64 is provided on the negative pressure chamber 63, through which a negative pressure can be formed in the negative pressure chamber 63. The enclosure 65 is closed at one end and has a receiving port 67 arranged circumferentially. The closed end of the enclosure 65 covers and connects to the open end of the negative pressure chamber 63, thereby forming a material stacking space. The closed end of the enclosure 65 is provided with a plurality of spaced and parallel sponge strips 66, and the sponge strips 66 are located in the material stacking space. In this way, when the product is injected into the material stacking space, the negative pressure is applied to the side of the product through the first through hole 631, thereby causing the side of the product to be adsorbed onto the surface of the sponge strips 66. The sponge strips 66 can deform to adapt to the extrusion pressure of the product, thereby tightly adhering to the side of the product, and the spacing between each sponge strip 66 and the side of the product creates a vacuum, thereby firmly adsorbing the product. Meanwhile, the length direction of the sponge strip 66 is consistent with the stacking direction of the product in the material stacking space. That is to say, the product is injected horizontally and stacked vertically in the material stacking space, and the sponge strip 66 is also set vertically. In this way, each product can fit tightly with the sponge strip 66, further improving the adsorption effect of the product.

[0052] Optionally, see again Figure 12 The negative pressure chamber 63 includes a second end plate 632 and multiple third side plates 633. The multiple third side plates 633 are connected end-to-end to form a cylindrical body open at both ends. The second end plate 632 is positioned at one opening of the cylindrical body, thus closing one end of the cylindrical body; that is, the second end plate 632 forms the closed end of the negative pressure chamber 63. Specifically, the second end plate 632 is square, and there are four third side plates 633, making the internal space of the negative pressure chamber 63 approximately rectangular. The second end plate 632 has a second through hole communicating with the negative pressure pipe 64.

[0053] The diameter of the first through hole 631 is smaller than the diameter of the second through hole. The second through hole is connected to the negative pressure pipe 64 and serves as an air convergence channel; therefore, its diameter should be set to be larger. A smaller diameter for the first through hole 631 can generate a more uniform negative pressure.

[0054] Optionally, see again Figure 11 and Figure 12The enclosure 65 includes a third end plate 651 and multiple fourth side plates 652. The third end plate 651 covers and connects to the opening end of the negative pressure chamber 63. Multiple first through holes 631 are provided on the third end plate 651. The multiple fourth side plates 652 are sequentially connected to form a semi-enclosed structure with openings at both ends and circumferential notches. The third end plate 651 covers and connects to one opening end of the semi-enclosed structure, and also covers and connects to the opening end of the negative pressure chamber 63. The notches formed by the connection of the multiple fourth side plates 652 serve as a material receiving port 67. Optionally, the third end plate 651 is square. Correspondingly, there are three fourth side plates 652, and the sides of the three fourth side plates 652 are connected to the three sides of the third end plate 651 respectively, thereby enclosing a material stacking space.

[0055] Optionally, see again Figure 12 The length L1 of the third end plate 651 along the product injection direction A is greater than the length L2 of the opening end of the negative pressure chamber 63 along the product injection direction A. This increases the depth of the product stacking space to accommodate large-sized products.

[0056] Optionally, see again Figure 12 The length L3 of the fourth side plate 652 along the product injection direction A, that is, the length of the upper and lower fourth side plates 652 (relative to the product injection direction A). Figure 12 The length L3 along the product injection direction A of the third end plate 651 is greater than the length L1 along the product injection direction A of the third end plate 651. This effectively supports large-sized products and prevents them from falling.

[0057] Based on the above detailed description, Figure 11 and Figure 12 It can be seen that the entire receiving hopper 62, except for the receiving port 67 which is open, has one end of the enclosure 65 ( Figure 12 The left side shown is also open, which allows for the adaptation of larger products.

[0058] Optionally, see again Figure 1 , Figure 2 , Figure 11 and Figure 12 The product conveying device 7 is also equipped with a product baffle 701 on its output side, and the plane of the product baffle 701 is arranged along the injection direction of the product. When the receiving mechanism 6 receives the product, the product baffle 701 blocks one end of the enclosure 65 that is in an open state, leaving only the receiving port 67 open for receiving the product. In this way, the product baffle 701 can guide the product, allowing the product to be stacked regularly within the enclosure 65.

[0059] Optionally, the negative pressure chamber 63 and the enclosure 65 are connected by welding.

[0060] Optionally, the second end plate 632 and the plurality of third side plates 633 are connected by welding or integral molding.

[0061] Optionally, the third end plate 651 and the plurality of fourth side plates 652 are connected by welding or integral molding.

[0062] Optionally, a plurality of first through holes 631 located at the intervals between two adjacent sponge strips 66 are arranged in a regular manner to generate a uniform negative pressure, thereby further improving the adsorption effect of the product.

[0063] Optionally, the negative pressure pipe 64 is connected to the second end plate 632 via a second connecting plate. Specifically, the second connecting plate has a third through hole, and the outer wall of one end of the negative pressure pipe 64 is welded into the third through hole. The second connecting plate is connected to the second end plate 632 by bolts.

[0064] Optionally, see again Figure 12 The receiving bin 62 also includes connecting bolts 68. One end of the connecting bolt 68 is connected to the outer wall of the negative pressure chamber 63. Specifically, one end of the connecting bolt 68 is connected to the outer wall of a third side plate 633. The connecting bolts 68 can be used to assemble the connecting arms 61 of the receiving bin 62. Optionally, there may be multiple connecting bolts 68.

[0065] Optionally, the receiving hopper 62 also includes an air pump connected to the negative pressure pipe 64. The generation of negative pressure can be controlled by switching the air pump on and off. Before receiving material in the receiving hopper 62, the air pump is turned on to generate negative pressure, and then the receiving hopper 62 is moved to one side of the conveyor belt to receive material. When it is time for the receiving hopper 62 to unload, the air pump is turned off, the negative pressure disappears, and the product falls under its own weight. Optionally, a negative pressure solenoid valve can be installed on the negative pressure pipe 64, and negative pressure and pressure relief can be achieved by controlling the switching of the negative pressure solenoid valve and the air pump.
