Description

Technical Field

[0001] This utility model relates to the field of automotive parts conveying technology, and more specifically, to a product alignment conveyor. Background Technology

[0002] The function of the automotive muffler end cap is to seal the muffler; it is generally oval-shaped. After the muffler end cap is manufactured, the product enters the conveyor belt through a chute perpendicular to the conveyor belt's direction of transport. To improve the space utilization of the packaging box, the long side of the product inside the box needs to be parallel to the long side of the conveyor belt. Because the products move in different postures to the conveyor belt exit end, they cannot all enter the packaging box at the exit end with a uniform posture for neat stacking. Moreover, even if the products can move to the conveyor belt exit end with the same posture, if the packaging box's position or size changes, it cannot be guaranteed that the product will fall accurately into the packaging box. Therefore, the current technology involves packing personnel grabbing the products at the conveyor belt exit end and packing them into boxes, ensuring that the products are neatly arranged in a specific posture and position inside the packaging box.

[0003] However, the above-mentioned technical solutions are not only very labor-intensive, but also the conveyor belt speed cannot be too fast in order to match the speed of manual packing, resulting in low product packing efficiency. Summary of the Invention

[0004] To address the problems of labor-intensive and inefficient packing processes that require manual product alignment and boxing in the existing technology, this utility model provides a product alignment conveyor that can align products and adjust their discharge position so that the products can accurately fall into the packaging box and be neatly stacked without manual boxing.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A product alignment conveyor includes a frame, a drive roller rotatably connected to the frame, a driven roller rotatably connected to the frame, a conveyor belt surrounding the drive roller and the driven roller, and a rotation drive mechanism for driving the drive roller to rotate; it also includes a first side baffle strip connected to the frame and located above the conveyor belt; a second side baffle strip connected to the frame and located above the conveyor belt; and a shifting drive mechanism that can drive the entire or part of the first side baffle strip to move along the width direction of the conveyor belt, and / or, the shifting drive mechanism can... The second side baffle strip is driven to move entirely or partially along the width direction of the conveyor belt; a straightening mechanism is disposed inside the first side baffle strip and / or the second side baffle strip, the straightening mechanism can guide the product placed on the conveyor belt to turn during travel; a travel channel for the product on the conveyor belt is formed between the inner sides of the first side baffle strip and the second side baffle strip, the end of the first side baffle strip in the direction of conveyor belt movement and the end of the second side baffle strip in the direction of conveyor belt movement together form a discharge port, the discharge port can be moved along the width direction of the conveyor belt under the drive of the shifting drive mechanism.

[0007] It is understood that the term "inner side" as used in this specification refers to the side of the relevant structure that is closer to the product on the conveyor belt, and the term "outer side" refers to the side of the relevant structure that is farther away from the product.

[0008] Since the operation and principle of the conveyor belt are existing technologies, they will not be described in detail here. In the above technical solution, the product first enters the conveyor belt along a feeding channel perpendicular to the conveyor belt in the conveying direction. The products that have just fallen into the conveyor belt are in a disordered state with varying rotation angles. As the product moves with the conveyor belt, it enters between the first and second side baffles, and then, guided by the straightening mechanism, it turns and straightens, finally passing through the discharge port and falling into the packaging box at the outlet end of the conveyor belt. When the size or position of the packaging box is changed, the shifting drive mechanism can drive the first and second side baffles to rotate, slide, rotate simultaneously, or slide simultaneously, causing the discharge port to move in the width direction of the conveyor belt, thereby changing the product's discharge position.

[0009] Preferably, the alignment mechanism includes a first alignment guide plate and a second alignment guide plate respectively connected to the inner sides of the first side baffle strip and the second side baffle strip. The first alignment guide plate includes a first rotary guide portion and a first straight guide portion, both of which are used to contact the product on their inner sides. The projection of the first rotary guide portion on the conveyor belt forms an angle with the long side of the conveyor belt. The projection of the first straight guide portion on the conveyor belt is parallel to the projection of the first side baffle strip on the conveyor belt. The first straight guide portion is closer to the discharge end of the conveyor belt than the first rotary guide portion. The second alignment guide plate is located between the discharge end of the conveyor belt and the first alignment guide plate. The second alignment guide plate includes a second rotary guide portion and a second straight guide portion, both of which are used to contact the product on their inner sides. The projection of the second rotary guide portion on the conveyor belt forms an angle with the long side of the conveyor belt. The projection of the second straight guide portion on the conveyor belt is parallel to the projection of the first straight guide portion on the conveyor belt. The second straight guide portion is closer to the discharge end of the conveyor belt than the second rotary guide portion.

[0010] When the first side baffle is parallel to the long side of the conveyor belt, after the product enters between the first and second side baffles, it will first contact the inner side of the first rotating guide. The first rotating guide will apply a component force to the product, pushing it towards the center of the conveyor belt, causing the product to rotate continuously on the conveyor belt. During this process, the contact point between the product and the first rotating guide will continuously change. Then, the product will contact the first straight guide, which will fine-tune it until its long side is parallel to the long side of the conveyor belt. Since the product may rotate slightly due to mechanical vibration during its movement to the conveyor belt's discharge end, after passing the first straightening guide, the second straightening guide can further adjust the product, thereby improving the straightening effect. The adjustment process and principle of the second straightening guide are the same as those of the first straightening guide, and therefore will not be described again here. It should be noted that if the position of the discharge port is changed by rotating the first and second side baffle strips, although the first and second straightening guide plates will also rotate after the first or second side baffle strips rotate, the combined force exerted by the two on the product remains unchanged and will not affect the straightening effect of the product. The product will eventually be straightened to a position with the long side facing forward.

[0011] Preferably, the system further includes a connector, through which the first side baffle strip and the second side baffle strip are connected; the starting ends of the first side baffle strip in the direction of conveyor belt movement are respectively located on opposite sides of the conveyor belt and are rotatably connected to the frame, and the rotation axes of the first side baffle strip and the second side baffle strip are both perpendicular to the conveying surface of the conveyor belt. The position of the discharge port can be changed by rotating the first side baffle strip and / or the second side baffle strip.

[0012] Preferably, the end of the first rotating guide portion away from the first straight guide portion is connected to the inner side of the first side baffle strip, and a first elastic element is connected between the outer side of the first straight guide portion and the inner side of the first side baffle strip; the end of the second rotating guide portion away from the second straight guide portion is connected to the inner side of the second side baffle strip, and a second elastic element is connected between the outer side of the second straight guide portion and the inner side of the second side baffle strip. When the product squeezes the first straight guide plate, the first straight guide portion is displaced; while the first elastic element is compressed and applies a thrust to the first straight guide portion, keeping the first straight guide plate in a suitable position to guide the product. The working process and principle of the second elastic element are similar to those of the first elastic element. It can be understood that the first and second elastic elements can respectively give the first and second straight guide plates certain buffering and adjustment capabilities, thereby being suitable for guiding different types and specifications of products, avoiding excessive resistance to some products and affecting the smooth transport of products.

[0013] Preferably, a first U-shaped member is provided on the outer side of the first side baffle strip, forming a first sliding groove between the first U-shaped member and the outer side of the first side baffle strip, with the long side of the first sliding groove parallel to the long side of the first side baffle strip; a second U-shaped member is provided on the outer side of the second side baffle strip, forming a second sliding groove between the second U-shaped member and the outer side of the second side baffle strip, with the long side of the second sliding groove parallel to the long side of the second side baffle strip; a first limiting rod and a second limiting rod are respectively provided at both ends of the connecting member, with one end of the first limiting rod extending into the first sliding groove and one end of the second limiting rod extending into the second sliding groove. During the synchronous rotation of the first and second side baffle strips, the first and second limiting rods maintain a certain distance, so that the first and second side baffle strips maintain a basically fixed distance. When the first and second side baffle strips rotate, the position of the first limiting rod in the first sliding groove changes, and the position of the second limiting rod in the second sliding groove changes, but neither of them will disengage from the first and second sliding grooves.

[0014] Preferably, the shifting drive mechanism includes a mounting base connected to the frame and a first cylinder. The cylinder body of the first cylinder is mounted on the mounting base, and the connecting member is connected to the piston rod of the first cylinder. The axis of the piston rod of the first cylinder is parallel to the wide side of the conveyor belt. A guide rod is provided on the mounting base, and a guide cylinder is provided on the connecting member. The guide cylinder and the guide rod are slidably connected along the width direction of the conveyor belt. The cooperation between the guide cylinder and the guide rod is used to improve the moving direction accuracy of the connecting member. By driving the connecting member to move, the first side baffle and the second side baffle can rotate simultaneously. When the first cylinder extends or retracts its piston rod, the connecting member slides along the width direction of the conveyor belt, and the discharge ends of the first side baffle and the second side baffle swing synchronously, thereby changing the position of the discharge port.

[0015] Preferably, a baffle plate is rotatably connected to the discharge end of the first side baffle strip or the second side baffle strip, and a switch driving mechanism is installed on the second side baffle strip. The switch driving mechanism is used to drive the baffle plate to rotate so that the discharge port opens or closes.

[0016] The shifting drive mechanism can be a motor, rotary cylinder, gear and rack drive mechanism, etc. that outputs rotary motion, or a linear cylinder, electric actuator, motor lead screw drive mechanism, etc. that outputs linear motion.

[0017] When the output quantity reaches a certain level, product conveying needs to be paused, the product discharge position switched, and then product conveying resumed to prevent product overflow. Therefore, preferably, a baffle plate is rotatably connected to the discharge end of the first or second side baffle strip, and a switch drive mechanism is installed on the second side baffle strip. The switch drive mechanism is used to drive the baffle plate to rotate, thereby opening or closing the discharge port. Under normal conveying conditions, the discharge port is open; when the output quantity reaches a set level, the switch drive mechanism drives the baffle plate to rotate and close the discharge port; after the position switching drive mechanism switches the discharge port position, the switch drive mechanism drives the baffle plate to rotate and open the discharge port again.

[0018] When the rotation axis of the baffle plate is perpendicular to the conveying surface of the conveyor belt, the switch drive mechanism can be a motor, rotary cylinder, gear and rack drive mechanism, etc. that outputs rotary motion; when the rotation axis of the baffle plate is parallel to the conveying surface of the conveyor belt, the switch drive mechanism can be a linear cylinder, electric actuator, motor lead screw drive mechanism, etc. that outputs linear motion.

[0019] Preferably, the baffle plate is rotatably connected to the first or second side baffle strip via a rotating shaft. The switch drive mechanism includes a second cylinder, a first chain link, and a second chain link. The cylinder body of the second cylinder is mounted on the outside of the first or second side baffle strip. One end of the first chain link is fixedly connected to the end of the piston rod of the second cylinder, and the other end of the first chain link is rotatably connected to one end of the second chain link. The other end of the second chain link is rotatably connected to the rotating shaft. When the second cylinder extends or retracts its piston rod, the baffle plate rotates, causing the discharge port to close or open. When the discharge port is open, the end of the piston rod of the second cylinder is retracted. When it is necessary to close the discharge port, the second cylinder extends its piston rod, and the second chain link moves with the piston rod of the second cylinder, thereby pushing the first chain link to rotate. The first chain link then drives the rotating shaft to rotate, causing the baffle plate to rotate.

[0020] Preferably, a counting sensor is mounted on the frame, located at the outlet end of the conveyor belt. When the number of products measured by the counting sensor reaches a certain value, the second cylinder immediately extends its piston rod to rotate the baffle plate, thereby closing the outlet. The counting sensor is used to calculate the number of products flowing out of the conveyor belt outlet so as to close the outlet in a timely manner.

[0021] Preferably, the frame is provided with a first limiting member and a second limiting member, which are located on both sides of the conveyor belt and are parallel to the long side of the conveyor belt. The first limiting member abuts against the outer side of the first side baffle, and the second limiting member abuts against the outer side of the second side baffle. The first and second limiting members are used to limit the rotation angle of the first and second side baffles, respectively. When a product needs to be output from one side of the conveyor belt, the first side baffle can be pushed to abut against the first limiting member; when a product needs to be output from the other side of the conveyor belt, the second side baffle can be pushed to abut against the second limiting member, thereby ensuring the accuracy of the product's discharge position and preventing the product from falling off the side of the conveyor belt.

[0022] It should be noted that the above technical solution is not limited to the alignment of elliptical products, but can also be used for the alignment of long and narrow products.

[0023] The beneficial effects of this utility model are:

[0024] (1) A first side baffle, a second side baffle, a shifting drive mechanism, and a straightening mechanism are installed above the conveyor belt. After the product enters between the first and second side baffles, the straightening mechanism can straighten the product to a specific posture so that the product falls into the packaging box in that posture. The shifting drive mechanism can drive the first and / or second side baffles to move, thereby changing the position of the discharge port. The combination of the straightening mechanism and the shifting drive mechanism can make the product fall into the packaging box in the same posture at the accurate position for neat stacking. Therefore, there is no need for manual handling for packing, which not only saves manpower but also improves the packing efficiency of the product.

[0025] (2) A first elastic element is connected between the first straightening guide plate and the first side baffle strip, and a second elastic element is connected between the second straightening guide plate and the second side baffle strip. This allows the first and second straightening guide plates to have certain buffering and adjustment capabilities, thus making them suitable for guiding different types and specifications of products and avoiding excessive resistance to some products, which would affect the smooth transport of the products.

[0026] (3) A baffle plate and a switch drive mechanism are installed at the discharge port. A counting sensor is installed at the discharge end of the conveyor belt. When the counting sensor detects that the output quantity of the product reaches a certain value, the switch drive mechanism can drive the baffle plate to rotate to close the discharge port. After the position of the discharge port is switched, the discharge port is opened again to continue conveying the product, thereby avoiding product overflow. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0035] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0036] Example 1

[0037] This embodiment is a first embodiment of a product alignment conveyor, such as... Figures 1 to 3As shown, it includes a frame 1, a drive roller (not shown) rotatably connected to the frame 1, a driven roller (not shown) rotatably connected to the frame 1, a conveyor belt 2 surrounding the drive roller and the driven roller, and a rotary drive mechanism 3 for driving the drive roller to rotate; it also includes a first side baffle 6 and a second side baffle 7 located above the conveyor belt 2 and connected by a connector 19, a shifting drive mechanism 10, and a straightening mechanism disposed inside the first side baffle 6 and / or the second side baffle 7 and capable of guiding the product 17 to a position where the long side of the product 17 is parallel to the long side of the conveyor belt 2; the feeding end of the first side baffle 6 and the second side baffle 7 are also included. The feed ends of strip 7 are located on opposite sides of conveyor belt 2 and are rotatably connected to frame 1, and the rotation axes of both are perpendicular to the conveying surface of conveyor belt 2; a travel channel for the product on conveyor belt 2 is formed between the inner sides of the first side baffle strip 6 and the second side baffle strip 7, and the end of the first side baffle strip 6 in the direction of movement of conveyor belt 2 and the end of the second side baffle strip 7 in the direction of movement of conveyor belt 2 enclose the discharge port 601; the shifting drive mechanism 10 is used to drive the first side baffle strip 6 and / or the second side baffle strip 7 to rotate, and the discharge port 601 can move along the width direction of conveyor belt 2 under the drive of the shifting drive mechanism.

[0038] Furthermore, the frame 1 is provided with a first limiting member 14 and a second limiting member 15. The first limiting member 14 and the second limiting member 15 are located on both sides of the conveyor belt 2 and are parallel to the long side of the conveyor belt 2. The first limiting member 14 is used to abut against the outer side of the first side baffle 6, and the second limiting member 15 is used to abut against the outer side of the second side baffle 7. The first limiting member 14 and the second limiting member 15 are used to limit the rotation angle of the first side baffle 6 and the second side baffle 7, respectively. When the product 17 needs to be output from one side of the conveyor belt 2, the first side baffle 6 can be rotated to abut against the first limiting member 14; when the product 17 needs to be output from the other side of the conveyor belt 2, the second side baffle 7 can be rotated to abut against the second limiting member 15, thereby ensuring the accuracy of the output position of the product 17 and preventing the product 17 from falling out from the side of the conveyor belt 2.

[0039] The working principle or workflow of this embodiment: Since the operation process and principle of the conveyor belt 2 are existing technologies, they will not be described in detail here. Figures 1 to 3As shown, the conveying direction of the feeding channel 16 is perpendicular to the conveying direction of the conveyor belt 2, and the feeding channel 16 is inclined. The product 17 first enters the conveyor belt 2 along the feeding channel 16, whose conveying direction is perpendicular to the conveyor belt 2. The product 17 is in a disordered state when it first falls into the conveyor belt 2, with different rotation angles. As it moves with the conveyor belt 2, the product 17 will enter between the first side baffle 6 and the second side baffle 7, and then turn and straighten under the guidance of the straightening mechanism, and finally pass through the discharge port 601 and fall into the packaging box at the outlet end of the conveyor belt 2. When the size of the packaging box is changed or the position of the packaging box is changed, the shifting drive mechanism 10 can drive the first side baffle 6 and the second side baffle 7 to rotate, so that the discharge port 601 moves in the width direction of the conveyor belt 2, thereby changing the discharge position of the product 17.

[0040] It is understood that the term "inner side" as used in this specification refers to the side of the relevant structure that is closer to the product 17 on the conveyor belt 2, and the term "outer side" refers to the side of the relevant structure that is farther away from the product 17.

[0041] The beneficial effects of this embodiment are as follows: A first side baffle, a second side baffle, a shifting drive mechanism, and a straightening mechanism are arranged above the conveyor belt. After the product enters between the first and second side baffles, the straightening mechanism can straighten the product to a specific posture, allowing it to fall into the packaging box in that posture. The shifting drive mechanism can drive the first and / or second side baffles to move, thereby changing the position of the discharge port. Combining the straightening mechanism and the shifting drive mechanism allows the product to fall into the packaging box in the correct position and with the same posture for neat stacking. Therefore, manual handling for packing is eliminated, saving manpower and improving packing efficiency.

[0042] Example 2

[0043] This embodiment is a second embodiment of a product alignment conveyor. This embodiment is similar to Embodiment 1, except that it combines... Figures 1 to 4As shown, the alignment mechanism includes a first alignment guide plate 4 and a second alignment guide plate 5 connected to the inner sides of the first side baffle strip 6 and the second side baffle strip 7, respectively. The first alignment guide plate 4 includes a first rotary guide portion 401 and a first straight guide portion 402, both of which are used to contact the product 17. The projection of the first rotary guide portion 401 on the conveyor belt 2 forms an angle with the long side of the conveyor belt 2. The projection of the first straight guide portion 402 on the conveyor belt 2 is parallel to the projection of the first side baffle strip 6 on the conveyor belt 2. One end of the first straight guide portion 402 is connected to one end of the first rotary guide portion 401, and the first straight guide portion 402 is closer to the discharge end of the conveyor belt 2 than the first rotary guide portion 401. The second aligning guide plate 5 is located between the discharge end of the conveyor belt 2 and the first aligning guide plate 4. The second aligning guide plate 5 includes a second rotating guide portion 501 and a second straight guide portion 502, both of which are used to contact the product 17 on their inner sides. The projection of the second rotating guide portion 501 on the conveyor belt 2 forms an angle with the long side of the conveyor belt 2. The projections of the second straight guide portion 502 and the first straight guide portion 402 on the conveyor belt 2 are parallel to each other. One end of the second straight guide portion 502 is connected to one end of the second rotating guide portion 501, and the second straight guide portion 502 is closer to the discharge end of the conveyor belt 2 than the second rotating guide portion 501.

[0044] When the first side baffle 6 is parallel to the long side of the conveyor belt 2, after the product 17 enters between the first side baffle 6 and the second side baffle 7, it will first contact the inner side of the first rotating guide 401. The first rotating guide 401 will apply a component force to the product 17 in the direction of pushing the product 17 towards the center of the conveyor belt 2, causing the product 17 to rotate continuously on the conveyor belt 2. During this period, the contact point between the product 17 and the first rotating guide 401 will continuously change. Then the product 17 will contact the first straight guide 402, and under the fine adjustment of the first straight guide 402, it will be completely aligned until its long side is parallel to the long side of the conveyor belt 2. Since the product 17 may rotate slightly due to mechanical vibration during its movement to the discharge end of the conveyor belt 2, after the product 17 passes the first aligning guide 4, the second aligning guide 5 can then further adjust the product 17, thereby improving the alignment effect of the product 17. The adjustment process and principle of the second aligning guide plate 5 for product 17 are the same as those of the first aligning guide plate 4, so they will not be described again here. It should be noted that if the position of the discharge port 601 is changed by rotating the first side baffle strip 6 and the second side baffle strip 7, although the first aligning guide plate 4 and the second aligning guide plate 5 will also rotate after the first side baffle strip 6 or the second side baffle strip 7 rotates, the combined force exerted by the two on product 17 remains unchanged and will not affect the aligning effect of product 17. Product 17 will eventually be aligned to a state where the long side faces forward.

[0045] Furthermore, the end of the first rotating guide 401 away from the first straight guide 402 is connected to the inner side of the first side baffle 6, and a first elastic member 8 is connected between the outer side of the first straight guide 402 and the inner side of the first side baffle 6; the end of the second rotating guide 501 away from the second straight guide 502 is connected to the inner side of the second side baffle 7, and a second elastic member 9 is connected between the outer side of the second straight guide 502 and the inner side of the second side baffle 7. Specifically, both the first elastic member 8 and the second elastic member 9 are springs. The axis of the first elastic member 8 is not perpendicular to the first straight guide 402, and the end of the first elastic member 8 connected to the first straight guide 402 is closer to the discharge port 601 than the other end; the axis of the second elastic member 9 is not perpendicular to the second straight guide 502, and the end of the second elastic member 9 connected to the second straight guide 502 is closer to the discharge port 601 than the other end. When product 17 presses against the first straightening guide plate 4, the first straight guide portion 402 is displaced; while the first elastic member 8 is compressed and applies a thrust to the first straight guide portion 402, keeping the first straightening guide plate 4 in a suitable position to guide product 17. The working process and principle of the second elastic member 9 are similar to those of the first elastic member 8. It can be understood that the first elastic member 8 and the second elastic member 9 can respectively provide the first straightening guide plate 4 and the second straightening guide plate 5 with certain buffering and adjustment capabilities, thus making them suitable for guiding different types and specifications of products 17, avoiding excessive resistance to some products 17 and affecting the smooth conveyance of products 17.

[0046] Furthermore, a first U-shaped member 20 is provided on the outer side of the first side baffle strip 6, forming a first sliding groove 2001 between the first U-shaped member 20 and the outer side of the first side baffle strip 6, with the long side of the first sliding groove 2001 parallel to the long side of the first side baffle strip 6; a second U-shaped member 21 is provided on the outer side of the second side baffle strip 7, forming a second sliding groove 2101 between the second U-shaped member 21 and the outer side of the second side baffle strip 7, with the long side of the second sliding groove 2101 parallel to the long side of the second side baffle strip 7; a first limiting rod 22 and a second limiting rod 23 are respectively provided at both ends of the connecting member 19, with one end of the first limiting rod 22 extending into the first sliding groove 2001 and one end of the second limiting rod 23 extending into the second sliding groove 2101. During the synchronous rotation of the first side baffle strip 6 and the second side baffle strip 7, the first limiting rod 22 and the second limiting rod 23 maintain a certain distance, so that the first side baffle strip 6 and the second side baffle strip 7 maintain a basically fixed distance. When the first side baffle strip 6 and the second side baffle strip 7 rotate, the position of the first limiting rod 22 in the first slide groove 2001 changes, and the position of the second limiting rod 23 in the second slide groove 2101 changes, but neither of them will disengage from the first slide groove 2001 and the second slide groove 2101.

[0047] Furthermore, the shifting drive mechanism 10 includes a mounting base 1001 connected to the frame 1 and a first cylinder 1002. The cylinder body of the first cylinder 1002 is mounted on the mounting base 1001, and the connecting member 19 is connected to the piston rod of the first cylinder 1002. The axis of the piston rod of the first cylinder 1002 is parallel to the wide side of the conveyor belt 2. The mounting base 1001 is provided with two guide rods 24, and the connecting member 19 is provided with four guide cylinders 25. Each pair of guide cylinders 25 is slidably connected to one guide rod 24 along the width direction of the conveyor belt 2. The cooperation between the guide cylinders 25 and the guide rods 24 can improve the accuracy of the moving direction of the connecting member 19. By driving the connecting member 19 to move, the first side baffle 6 and the second side baffle 7 can be rotated simultaneously. When the first cylinder 1002 extends or retracts its piston rod, the connecting member 19 slides along the width direction of the conveyor belt 2, and the discharge ends of the first side baffle 6 and the second side baffle 7 swing synchronously, thereby changing the position of the discharge port 601.

[0048] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0049] Example 3

[0050] This embodiment is a third embodiment of a product 17 alignment conveyor. This embodiment is similar to embodiment 2, except that it combines... Figures 1 to 5 As shown, a baffle plate 11 is rotatably connected to the discharge end of the second side baffle strip 7, and a switch drive mechanism 12 is installed on the second side baffle strip 7. The switch drive mechanism 12 is used to drive the baffle plate 11 to rotate, thereby opening or closing the discharge port 601. Under normal feeding conditions, the discharge port 601 is in the open state; when the output product 17 reaches the set quantity, the switch drive mechanism 12 drives the baffle plate 11 to rotate to close the discharge port 601; after the position change drive mechanism switches the position of the discharge port 601, the switch drive mechanism 12 drives the baffle plate 11 to rotate to open the discharge port 601 again, thereby preventing the product 17 from overflowing.

[0051] Furthermore, the baffle plate 11 is rotatably connected to the second side baffle strip 7 via a rotating shaft 1204. The switch drive mechanism 12 includes a second cylinder 1201, a first chain link 1202, and a second chain link 1203. The cylinder body of the second cylinder 1201 is installed on the outside of the second side baffle strip 7. One end of the first chain link 1202 is fixedly connected to the end of the piston rod of the second cylinder 1201, and the other end of the first chain link 1202 is rotatably connected to one end of the second chain link 1203. The other end of the second chain link 1203 is rotatably connected to the rotating shaft 1204. When the second cylinder 1201 extends or retracts its piston rod, the baffle plate 11 flips downwards, thereby closing or opening the discharge port 601. When the discharge port 601 is in the open state, the end of the piston rod of the second cylinder 1201 is in the retracted state. When the discharge port 601 needs to be closed, the second cylinder 1201 extends its piston rod, and the second chain link 1203 moves with the piston rod of the second cylinder 1201, thereby pushing the first chain link 1202 to rotate. The first chain link 1202 then drives the rotating shaft 1204 to rotate, causing the baffle plate 11 to rotate.

[0052] Furthermore, a counting sensor 13 is installed on the frame 1, located at the outlet end of the conveyor belt 2. When the number of products 17 measured by the counting sensor 13 reaches a certain value, the second cylinder 1201 immediately extends its piston rod to rotate the baffle plate 11, thereby closing the discharge port 601. The counting sensor 13 is used to calculate the number of products 17 flowing out from the outlet end of the conveyor belt 2 so as to close the discharge port 601 in a timely manner.

[0053] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.
