Description

Technical Field

[0001] This invention relates to the field of paper feeding technology, and in particular to a hopper for preventing material spillage. Background Technology

[0002] In a common paper feeding structure, the paper assembly position is on the front side, so paper can only be added from the back. The rear view is obstructed, and you can't see the front when adding paper. You can only place the paper by feel, which makes it easy for it to scatter and for the positioning to be inaccurate. Especially when the paper is irregularly shaped, you can grab a stack by hand and add it blindly, which makes it easy to spill. This increases the difficulty of adding paper and reduces production efficiency.

[0003] Existing technologies, such as the semi-automatic filter rod hopper feeding device with patent number CN201920054779.3, involve a flap that, before flipping, forms a 135°–150° angle with the hopper plane. A box of filter rods is placed on the flap, and a stop block underneath prevents the box from sliding down. A limiting block keeps the box centered on the flap. When the hopper descends to a predetermined height, the operator grasps the handle under the flap and flips the flap and the box of filter rods upwards along the hinge until the flap is parallel to the hopper. During the flipping process, even force and a uniform speed must be maintained; a slow flipping speed may cause the filter rods to fall out. The top opening of the filter rod box is open; after flipping up, the opening faces downwards, and the filter rods fall onto the filter rod surface due to gravity. The box is then removed, and the flap flips down, completing one feeding cycle. Although the filter rods are fed by connecting the flap to the hopper, for paper feeding, materials usually need to be added when there is still material in the hopper to ensure work efficiency. Although the existing technology can add the material to be added to the hopper, how to avoid material scattering caused by the distance when connecting the materials? Summary of the Invention

[0004] The purpose of this invention is to provide a silo that prevents materials from scattering, thus solving the problem of materials easily scattering during material handling.

[0005] The present invention is implemented as follows: a hopper for preventing material spillage includes a first hopper and a second hopper that can be docked with the first hopper. The second hopper and the first hopper are docked to form at least one material channel. The hopper also includes a guide member that can slide from the second hopper to the first hopper and a limiting part that can limit the guide member. The guide member is pluggably disposed in the material channel of the first hopper and the second hopper.

[0006] The first and second hoppers can be connected. When feeding the second hopper, the guide component's limiting part helps to keep the material in the second hopper compact and prevent it from scattering. After the second hopper is connected to the first hopper, the material in the second hopper can slide into the first hopper after being pulled out of the limiting part by the guide component. After the material in the first hopper is properly connected, the guide component is pulled out of the material channel, achieving seamless connection between the remaining material in the first hopper and the new material, effectively preventing the material from scattering.

[0007] A further technical solution of the present invention is: the guiding component includes a material stop and a sliding member, the material stop is pluggable in the material channel and can be limited by the limiting part, and the sliding member drives the material stop to slide along the first hopper and the second hopper.

[0008] A further technical solution of the present invention is that the stop member and the sliding member are detachably connected.

[0009] After the second hopper is filled with paper, it is lifted up to connect with the first hopper. The baffle is pulled out from the limiting part, and the sliding part drives the baffle to slide, so that the guide component can send material to the first hopper. After sliding to the material docking point, the baffle in the guide component is completely pulled out. At this time, the newly added material and the remaining material can be seamlessly connected, avoiding the problem of material scattering in the hopper.

[0010] A further technical solution of the present invention is: a locking mechanism is provided between the first hopper and the second hopper.

[0011] A further technical solution of the present invention is: the locking mechanism includes a locking member and a locking pin, the locking member is installed on the back of the second hopper and is rotatable, and the locking pin passes through the locking member and is limited and engaged with the pin holes on the back of the first hopper and the back of the second hopper.

[0012] After the second hopper is filled with paper, lift the second hopper upwards to connect with the first hopper, unscrew the locking device, and the first and second hoppers will be locked and limited.

[0013] The locking mechanism is rotatably mounted on the back of the second hopper. The locking mechanism has a locking pin. When the locking mechanism rotates upwards, the locking pin inserts into the pin hole of the second hopper. At this point, the second hopper can rotate downwards to a suitable position for adding paper. After the second hopper is filled, the locking mechanism rotates downwards, and the locking pin inserts into the pin hole on the back of the bottom of the first hopper. At this point, the second hopper and the first hopper are in close contact and will not tilt downwards. This frees up the operator's hands to feed paper into the first hopper.

[0014] A further technical solution of the present invention is that the limiting part is a limiting groove formed on the second hopper.

[0015] A further technical solution of the present invention is: the first silo is inclined, and the second silo is hinged at one end where it connects with the first silo.

[0016] Because the first hopper is tilted and positioned at the front, materials can only be added from the back, and the situation at the front cannot be observed from the back. By connecting the second hopper to the first hopper and allowing the second hopper to be flipped, materials can be added to the first hopper when it needs to be replenished. This eliminates the need to reach the front to add materials, greatly reducing the difficulty of adding materials.

[0017] The second hopper is connected to the top of the first hopper via a hinge. The rotation angle of the second hopper can be seamlessly connected with that of the first hopper, ensuring smooth and unobstructed downward conveyance of the paper sheets.

[0018] A further technical solution of the present invention is: the hopper further includes a support member, which is placed below the second hopper to support the second hopper, and the top of the support member is horizontal.

[0019] Before the second hopper replenishes the first hopper, the second hopper needs to be filled first. The second hopper is equipped with a support component. Rotate the second hopper onto the support component. The top of the support component is horizontal to ensure the visibility of the material being fed into the second hopper and to keep the material neat.

[0020] A further technical solution of the present invention is: the material channel on the first silo includes an open chute, a limiting chute, and a transition groove placed between the open chute and the limiting chute, the open chute being clearance-fitted with the material, the limiting chute being interference-fitted with the material, and the open chute being close to the second silo.

[0021] The semicircle below the material is tightly attached to the material channel of the first hopper. The material channel includes an open chute and a limiting chute, which are connected by a transition groove. The opening chute is located in front of the limiting chute. The opening chute is loosely fitted with the material. This makes the irregular paper pieces fit relatively loosely in the opening chute section, making the addition of paper pieces much smoother. After the paper pieces are slowly guided into the limiting chute through the transition chute, the limiting chute is interference-fitted with the material, so that the limiting chute can control the paper pieces and obtain a certain positioning accuracy to meet the assembly requirements and ensure that there is no jamming when adding paper pieces.

[0022] A further technical solution of the present invention is: the first silo is equipped with a sensor for detecting materials.

[0023] The hopper can be filled with materials without stopping the machine. The first hopper is equipped with a sensor. When it detects that there are no paper pieces, the sensor transmits the signal to the alarm to remind you to add paper pieces. The sensor is located in the middle of the material conveying direction of the first hopper. There is a distance below this position where paper pieces are stored. The paper pieces at this height have a certain weight, which ensures that they will not be scattered when the paper pieces are picked up, and that the supply of paper pieces can continue.

[0024] The beneficial effects of this invention are as follows: The first and second hoppers of this invention can be connected. When feeding the second hopper, the material in the second hopper is compacted and will not scatter due to the cooperation of the guiding component and the limiting part. After the second hopper is connected to the first hopper, the material in the second hopper can slide into the first hopper after being pulled out from the limiting part by the guiding component. After the material in the first hopper is connected in place, the guiding component is pulled out from the material channel, so that the remaining material in the first hopper can be seamlessly connected with the new material, effectively avoiding the scattering of materials.

[0038] Example 1:

[0039] Figure 1-10 A hopper for preventing material spillage is shown, comprising a first hopper 1 and a second hopper 2 that can dock with the first hopper 1, the second hopper 2 docking with the first hopper 1 to form at least one material channel, the hopper further comprising a guide member 3 that can slide from the second hopper 2 to the first hopper 1 and a limiting part 4 that can limit the guide member 3, the guide member 3 being pluggably disposed in the material channel of the first hopper 1 and the second hopper 2.

[0040] The first and second hoppers can be connected. When feeding the second hopper, the guide component's limiting part helps to keep the material in the second hopper compact and prevent it from scattering. After the second hopper is connected to the first hopper, the material in the second hopper can slide into the first hopper after being pulled out of the limiting part by the guide component. After the material in the first hopper is properly connected, the guide component is pulled out of the material channel, achieving seamless connection between the remaining material in the first hopper and the new material, effectively preventing the material from scattering.

[0041] In this embodiment, the material is an irregularly shaped paper piece, which is a decorative part on the medicine box. It is connected to the medicine box by a pin, so the hopper must ensure that the paper piece has a certain positioning accuracy. The hopper uses the semicircle below the paper piece as a limit to ensure positioning accuracy.

[0042] In this embodiment, the guiding member 3 includes a baffle 31 and a sliding member. The baffle 31 is pluggable in the material channel and can be limited by the limiting part 4. The sliding member drives the baffle 31 to slide along the first hopper 1 and the second hopper 2.

[0043] In this embodiment, the stopper 31 is detachably connected to the sliding member.

[0044] After the second hopper is filled with paper, it is lifted up to connect with the first hopper. The baffle is pulled out from the limiting part, and the sliding part drives the baffle to slide, so that the guide component can send material to the first hopper. After sliding to the material docking point, the baffle in the guide component is completely pulled out. At this time, the newly added material and the remaining material can be seamlessly connected, avoiding the problem of material scattering in the hopper.

[0045] In this embodiment, the second hopper is connected to a guide member via an industrial slide rail, and the guide member can slide from the first hopper to the second hopper.

[0046] In this embodiment, a locking mechanism 5 is provided between the first hopper 1 and the second hopper 2.

[0047] In this embodiment, the locking mechanism 5 includes a locking member 51 and a locking pin 52. The locking member 51 is installed on the back of the second hopper 2 and is rotatable. The locking pin 52 passes through the locking member 51 and engages with the pin holes on the back of the first hopper 1 and the back of the second hopper 2.

[0048] After the second hopper is filled with paper, lift the second hopper upwards to connect with the first hopper, unscrew the locking device, and the first and second hoppers will be locked and limited.

[0049] The locking mechanism is rotatably mounted on the back of the second hopper. The locking mechanism has a locking pin. When the locking mechanism rotates upwards, the locking pin inserts into the pin hole of the second hopper. At this point, the second hopper can rotate downwards to a suitable position for adding paper. After the second hopper is filled, the locking mechanism rotates downwards, and the locking pin inserts into the pin hole on the back of the bottom of the first hopper. At this point, the second hopper and the first hopper are in close contact and will not tilt downwards. This frees up the operator's hands to feed paper into the first hopper.

[0050] In this embodiment, the limiting part 4 is a limiting groove 42 formed on the second hopper 2.

[0051] In this embodiment, the first hopper 1 is inclined, and the second hopper 2 is hinged at one end to the first hopper 1.

[0052] Because the first hopper is tilted and positioned at the front, materials can only be added from the back, and the situation at the front cannot be observed from the back. By connecting the second hopper to the first hopper and allowing the second hopper to be flipped, materials can be added to the first hopper when it needs to be replenished. This eliminates the need to reach the front to add materials, greatly reducing the difficulty of adding materials.

[0053] The second hopper is connected to the top of the first hopper via a hinge. The rotation angle of the second hopper can be seamlessly connected with that of the first hopper, ensuring smooth and unobstructed downward conveyance of the paper sheets.

[0054] In this embodiment, the first hopper is an inclined straight hopper, and the second hopper is an auxiliary hopper. A set of auxiliary hoppers with a flip-up angle are connected above the inclined straight hopper by a hinge. The paper is first put into the auxiliary hopper, and then the auxiliary hopper flips to align with the inclined straight hopper and sends the paper into the inclined straight hopper to complete the paper replenishment. This method reduces the difficulty of adding paper and greatly improves work efficiency.

[0055] In this embodiment, the hopper further includes a support member 6, which is placed below the second hopper 2 to support the second hopper 2, and the top of the support member 6 is horizontal.

[0056] Before the second hopper replenishes the first hopper, the second hopper needs to be filled first. The second hopper is equipped with a support component. Rotate the second hopper onto the support component. The top of the support component is horizontal to ensure the visibility of the material being fed into the second hopper and to keep the material neat.

[0057] In this embodiment, the material channel on the first silo 1 includes an open chute 7, a limiting chute 8, and a transition groove 9 placed between the open chute 7 and the limiting chute 8. The open chute 7 is clearance-fitted with the material, and the limiting chute 8 is interference-fitted with the material. The open chute 7 is close to the second silo 2.

[0058] The semicircle below the material is tightly attached to the material channel of the first hopper. The material channel includes an open chute and a limiting chute, which are connected by a transition groove. The opening chute is located in front of the limiting chute. The opening chute is loosely fitted with the material. This makes the irregular paper pieces fit relatively loosely in the opening chute section, making the addition of paper pieces much smoother. After the paper pieces are slowly guided into the limiting chute through the transition chute, the limiting chute is interference-fitted with the material, so that the limiting chute can control the paper pieces and obtain a certain positioning accuracy to meet the assembly requirements and ensure that there is no jamming when adding paper pieces.

[0059] In this embodiment, the first hopper 1 is equipped with a sensor 10 for detecting materials.

[0060] The hopper can be filled with materials without stopping the machine. The first hopper is equipped with a sensor. When it detects that there are no paper pieces, the sensor transmits the signal to the alarm to remind you to add paper pieces. The sensor is located in the middle of the material conveying direction of the first hopper. There is a distance below this position where paper pieces are stored. The paper pieces at this height have a certain weight, which ensures that they will not be scattered when the paper pieces are picked up, and that the supply of paper pieces can continue.

[0061] In this embodiment, a lever is fixed below each material channel. Each lever is adjusted to a distance of 1mm from the paper to prevent the paper from falling. When the suction cup picks up the paper, it lifts the paper up, and the cylinder quickly retracts to pull the paper out of the channel.

[0062] In this embodiment, an industrial slide rail is fixed on each side of the second hopper, and the guide component slides on both sides of the industrial slide rail to slide to the first hopper; the sliding component is provided with a slot for limiting the baffle plate, the baffle plate passes through the slot of the sliding component and is inserted into the limiting part, the material is put into the material channel of the second hopper, and then the rear baffle 13 is inserted into the second hopper to prevent the paper pieces already put into the material channel from tilting and falling out.

[0063] In this embodiment, the locking component is connected to the back of the second hopper via a shoulder screw. The locking component can rotate around the shoulder screw and has a locking pin, which is a spring pin. When the locking component rotates upward, the spring pin is inserted into the pin hole of the second hopper. At this time, the second hopper can rotate downward to make it horizontal, which facilitates the addition of paper sheets. After the second hopper is filled, the locking component rotates downward, and the spring pin is inserted into the pin hole on the back of the bottom of the first hopper. At this time, the second hopper and the first hopper are in close contact and will not tilt downward. The operator can free up their hands to feed the paper sheets downward.

[0064] The working principle of this invention is as follows: Material 11 is sequentially placed into the material channel of the second hopper, and then the rear baffle 13 of the corresponding channel is fastened. Figure 1 As shown; lift the second hopper upwards using handle 12 until it aligns with the first hopper, as shown. Figure 2Then rotate the locking mechanism downwards, and the locking pin inserts into the pin hole on the back of the first hopper. At this point, the second hopper is flush with the first hopper and will not tilt downwards. Figure 3 ; Pull the stop in the guide component outward a certain distance so that it is disengaged from the limiting part, such as Figure 4 Slide the guide component towards the first hopper until it is close to the top of the remaining paper sheets in the first hopper, then pull the guide component out of the material channel so that the paper sheets in the second hopper connect with the remaining paper sheets. Figure 5 The sliding guide component returns to its original position in the second hopper, as shown below. Figure 6 Rotate the locking component upwards, and insert the locking pin into the pin hole on the back of the second hopper, as shown. Figure 7 Lower the second hopper, guide the component back into the limiting part of the second hopper, and continue adding paper sheets, such as... Figure 8 The process of feeding material into the first hopper is completed sequentially.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
