Description

Technical Field

[0001] The invention belongs to the technical field of packaging machines, in particular to a full-automatic bagging packaging machine. Background Art

[0002] There are three main types of full-automatic packaging machines in the domestic market: bag-making type, bag-feeding type, and can-feeding type. Bag-making full-automatic packaging machines usually consist of two parts: a bag-making machine and a weighing machine. The weighing machine can be either a weighing type or a screw type, and can package both granular and powdery materials. This machine is an automatic packaging equipment that directly makes bags with packaging film and completes metering, filling, coding, cutting and other actions during the bag-making process.

[0003] Putty powder is a kind of building decoration material. Its main ingredients are talcum powder and glue. Generally, putty is a base material used for wall repair and leveling. Usually putty is made of a small amount of paint base, a large amount of filler and an appropriate amount of coloring pigment. It has good adhesion. Generally, putty powder is collected in packaging bags, which is convenient for use and transportation. Some automatic putty powder packaging machines have also appeared in real life, such as a Chinese patent with application number CN201920820413.2. The technical solution includes a support frame and a second motor. The first rotating rod is connected to the front and rear sides of the lower end of the support frame, the left end outer surface of the first rotating rod is fixedly connected to a pulley, the outer surface of the first rotating rod is connected to a wire rope, the upper end of the connecting block is fixedly connected to a support plate, the upper inner end of the side plate is movably connected to a clamp, the inner side of the outer end of the clamp is fixedly connected to a spring, the upper right end of the packaging bag is connected to a feed port, the lower inner part of the storage bin is engaged with a baffle, the upper left end of the tooth plate is connected to a gear, the second motor is located on the lower left side of the storage bin, and a limiting block is fixedly connected to the upper inner side of the support frame. Although this technical solution does not require manpower to fix and transport the packaging bags, saving manpower and improving work efficiency, putty powder adheres to the inner wall of the storage bin of the packaging machine in this technical solution. Since the storage bin is located at the top of the packaging machine, during daily cleaning and maintenance of the packaging machine equipment, due to the different diameters between the inlet and the outlet of the storage bin, the staff needs to use cleaning tools to repeatedly clean the inner wall surface of the storage bin, which not only reduces the cleaning efficiency but also increases the work intensity of the staff.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 5 As shown, the fully automatic bagging packaging machine of the present invention comprises a cleaning unit 4 and a feed hopper 1; the top of the feed hopper 1 is designed to be square; the cleaning unit 4 is located on the surface of the top of the inner wall of the feed hopper 1; the top surface of the cleaning unit 4 is fixedly connected to an electric push rod 2, and the electric push rod 2 is installed on the outer surface of the feed hopper 1;

[0029] The cleaning unit 4 has uniformly arranged first sliding grooves 41 in its interior; a first cleaning plate 42 is slidably connected to the first sliding groove 41 via a first elastic member;

[0030] During operation, when the automatic putty powder packaging machine is used, some putty powder will remain on the inner wall of the storage bin of the packaging machine. Since the storage bin is located at the top of the packaging machine, during daily cleaning and maintenance of the packaging machine equipment, due to the difference in diameter between the entrance of the storage bin and the outlet of the storage bin, the staff needs to use cleaning tools to repeatedly clean the inner wall surface of the storage bin, which not only reduces the cleaning efficiency but also increases the work intensity of the staff. The feed hopper 1 is designed to be square, and the feed port diameter at the top of the feed hopper 1 is larger than the outlet diameter at the bottom of the feed hopper 1, so that it is convenient for the staff to input putty powder into the feed hopper 1. A cleaning unit 4 is installed on the top surface of the inner wall of the feed hopper 1, and an electric push rod 2 is fixedly connected to the top surface of the cleaning unit 4. The electric push rod 2 is started, and the thrust of the electric push rod 2 is used to drive the cleaning unit 4 to move. Since the cleaning unit 4 is evenly arranged inside The first sliding groove 41 has a first cleaning plate 42 slidably connected inside the first sliding groove 41. The length of the first cleaning plate 42 is equal to the length of the first sliding groove 41. The bottom of the first cleaning plate 42 is close to the inner wall surface of the feed hopper 1. The first sliding groove 41 and the first cleaning plate 42 are fixedly connected by a first elastic member. In the initial state, the first cleaning plate 42 uses the elastic force of the first elastic member to make the end of the first cleaning plate 42 away from one end of the first elastic member close to the adjacent inner wall of the side wall where the cleaning unit is located in the feed hopper 1. During the movement of the cleaning unit 4 toward the bottom of the feed hopper 1, the diameter of the inner wall of the feed hopper 1 gradually becomes shorter, and the first cleaning plate 42 gradually shrinks into the space inside the first sliding groove 41, so that the inner wall of the feed hopper 1 can be cleaned at one time, which effectively reduces the work intensity of the staff, and simultaneously improves the cleaning efficiency of the inner wall of the feed hopper 1, and can also reduce the waste of dust materials.

[0031] As an embodiment of the present invention, the cleaning unit 4 is provided with uniformly arranged second slide grooves 45, and the second slide grooves 45 are located below the first slide grooves 41; the second cleaning plate 47 is slidably connected to the second slide grooves 45 via a second spring 46;

[0032] A brush 474 is fixedly connected to the surface of one end of the second cleaning plate 47 close to the inner wall of the feed hopper 1; a third cleaning plate 48 is fixedly connected to the bottom of the side wall between the first chute 41 and the second chute 45;

[0033] During operation, a uniformly arranged second slide groove 45 is provided inside the cleaning unit 4, a second cleaning plate 47 is slidably connected inside the second slide groove 45, and the second slide groove 45 and the second cleaning plate 47 are fixedly connected by a second spring 46, so that the second cleaning plate 47 can shrink and extend with the first cleaning plate 42, and a brush 474 is fixedly connected to the surface of one end of the second cleaning plate 47 close to the inner wall of the feed hopper 1. When the electric push rod 2 drives the cleaning unit 4 to move downward, it simultaneously drives the brush 474 at the bottom of the second cleaning plate 47 to move. The brush 474 can remove stubborn dust on the inner wall surface of the feed hopper 1 during the movement. In order to avoid residual dust at the bottom of the cleaning unit 4 Dust is removed by fixing a third cleaning plate 48 at the bottom of the side wall between the first slide groove 41 and the second slide groove 45, so that the cleaning unit 4 can synchronously drive the third cleaning plate 48 to move during the movement, thereby avoiding dust residue at the bottom of the cleaning unit 4. Since the first cleaning plate 42 and the second cleaning plate 47 extend from the first slide groove 41 and the second slide groove 45 respectively, the middle position of the bottom of the cleaning unit 4 cannot be cleaned. Similarly, the dust on the inner wall of the feed hopper 1 cannot be cleaned, so it is necessary to use the third cleaning plate 48 to clean the middle position of the bottom of the cleaning unit 4, so as to further clean the inner wall surface of the feed hopper 1 and reduce the accumulation of dust on the inner wall surface of the feed hopper 1.

[0034] As an embodiment of the present invention, the first elastic member is a first spring 43;

[0035] During operation, the first elastic member is the first spring 43 , so that the elastic force of the first elastic member can be increased, so that the elastic force of the first elastic member can flexibly drive the first cleaning plate 42 to move in the first sliding groove 41 .

[0036] As an embodiment of the present invention, the cross-sections of the first cleaning plate 42 and the third cleaning plate 48 are both trapezoidal in design;

[0037] During operation, the cross-sections of the first cleaning plate 42 and the third cleaning plate 48 are both trapezoidal in design, so that the first cleaning plate 42 and the third cleaning plate 48 can contact the stubborn dust remaining on the inner wall surface of the feed hopper 1 during the process of cleaning the inner wall of the feed hopper 1, and can play a role in shoveling away the stubborn dust, thereby effectively reducing the dust accumulation on the inner wall of the feed hopper 1.

[0038] As an embodiment of the present invention, the upper surface of the feed hopper 1 is fixedly connected with uniformly arranged limit rods 11, and the electric push rod 2 is clamped between two adjacent limit rods 11; the side of the electric push rod 2 is fixedly connected with uniformly arranged support rods 21;

[0039] During operation, by fixing and connecting uniformly arranged limit rods 11 on the upper surface of the feed hopper 1, the electric push rod 2 can be clamped between two adjacent limit rods 11, effectively avoiding displacement when installing the cleaning unit 4 and the electric push rod 2, and by fixing and connecting uniformly arranged support rods 21 on the side of the electric push rod 2, the reaction force generated when the electric push rod 2 moves toward the bottom of the feed hopper 1 can be effectively avoided to cause the electric push rod 2 to shake, thereby ensuring the stability of the electric push rod 2 and facilitating disassembly, which is convenient for the later maintenance of the cleaning unit 4 and the parts inside the feed hopper 1.

[0040] As an embodiment of the present invention, the top of the cleaning unit 4 is fixedly connected to an air storage chamber 3; a sliding plate 31 is sealed and slidably connected to the inner wall of the air storage chamber 3; the end of the electric push rod 2 is fixedly connected to the sliding plate 31; the bottom of the air storage chamber 3 is provided with uniformly arranged exhaust holes 34; an exhaust groove 44 is provided inside the cleaning unit 4, and the top of the exhaust groove 44 is connected to the exhaust hole 34; a first exhaust hole is uniformly arranged on the side wall between the first slide groove 41 and the second slide groove 45; the first exhaust hole is connected to the exhaust groove 44, and the first exhaust hole is aligned with the inclined surface of the third cleaning plate 48;

[0041] During operation, since the top of the cleaning unit 4 is fixedly connected to the air storage chamber 3, and the inner wall of the air storage chamber 3 is sealed and slidably connected with a sliding plate 31, the end of the electric push rod 2 is fixedly connected to the sliding plate 31, so that the electric push rod 2 drives the sliding plate 31 inside the air storage chamber 3 to move synchronously during the movement process, and the sliding plate 31 will compress the gas in the space of the air storage chamber 3 during the downward movement. Since the bottom of the air storage chamber 3 is provided with uniformly arranged exhaust holes 34, the exhaust holes 34 are connected with the air outlet groove 44 inside the cleaning unit 4, so that the compressed gas in the space of the air storage chamber 3 is discharged along the exhaust holes 34 and flows into the space in the air outlet groove 44, and then is connected with the first air outlet hole through the air outlet groove 44, so that the gas in the space in the air outlet groove 44 is ejected along the first air outlet hole, and the first air outlet hole is aligned with the inclined surface design of the third cleaning plate 48, so that the gas in the space along the first air outlet hole The ejected gas can clean the surface of the third cleaning plate 48, effectively preventing dust from long-term accumulation on the surface of the third cleaning plate 48 and affecting the cleaning effect of the third cleaning plate 48. After the electric push rod 2 pushes the sliding plate 31 to the bottom of the air storage chamber 3, the electric push rod 2 continues to extend, driving the cleaning unit 4 to move toward the bottom of the feed hopper 1, thereby completing the cleaning of the inner wall of the hopper. At the same time, after the cleaning is complete, the electric push rod 2 contracts and drives the sliding plate 31 to move to its original position. In the process of the sliding plate 31 moving to its original position, the space in the air storage chamber 3 increases and the pressure decreases, so that the outside air is drawn into the air storage chamber 3. Afterwards, after the sliding plate 31 returns to its original position, the electric push rod 2 continues to contract and drives the cleaning unit 4 to move as a whole through the sliding plate 31, so that the cleaning unit 4 returns to its initial position and waits for the next cleaning.

[0042] As an embodiment of the present invention, the bottom of the air storage chamber 3 is fixedly connected with uniformly arranged air inlet holes 32; the inside of the air inlet holes 32 is fixedly connected with a one-way valve 33;

[0043] During operation, the bottom of the air storage chamber 3 is fixedly connected with evenly arranged air inlet holes 32. When the electric push rod 2 contracts, the electric push rod 2 drives the sliding plate 31 to move synchronously to the top of the air storage chamber 3. During the upward movement of the sliding plate 31, the air in the space outside the air storage chamber 3 is drawn into the space inside the air storage chamber 3 through the air inlet holes 32. The one-way valve 33 is fixedly connected inside the air inlet holes 32, so that the gas in the air storage chamber 3 can only enter the space inside the air storage chamber 3 along the air inlet holes 32, and the air in the space inside the air storage chamber 3 cannot be discharged along the air inlet holes 32, thereby effectively preventing the gas in the space inside the air storage chamber 3 from flowing out along the air inlet holes 32, thereby providing sufficient gas power for cleaning the dust on the surface of the third cleaning plate 48.

[0044] As an embodiment of the present invention, a cavity 471 is provided inside the second cleaning plate 47; a support plate 473 is slidably connected to the inside of the cavity 471 through a second elastic member; a brush 474 is fixedly connected to one end of the support plate 473 close to the inner wall of the feed hopper 1;

[0045] During operation, since a cavity 471 is provided inside the second cleaning plate 47, a support plate 473 is sealed and slidably connected inside the cavity 471, so that the support plate 473 can slide up and down smoothly in the cavity 471, and the support plate 473 is fixedly connected to the inner wall of the cavity 471 by a uniformly arranged second elastic member, so that the second elastic member prevents the support plate 473 from directly contacting the inner wall of the top of the cavity 471, and the elastic force of the second elastic member is used to drive the support plate 473 to move toward the inner wall of the feed hopper 1, and a brush 474 is fixedly connected to one end of the support plate 473 close to the inner wall of the feed hopper 1, so that the brush 474 on the surface of the support plate 473 is always in close contact with the inner wall surface of the feed hopper 1, thereby further completing the cleaning of the inner wall surface of the feed hopper 1, and effectively avoiding the situation where the brush 474 does not contact the surface of the feed hopper 1 during the movement of the cleaning unit 4, thereby causing the brush 474 to be unable to clean the inner wall surface of the feed hopper 1.

[0046] As an embodiment of the present invention, the second elastic member is an elastic ball 472; the elastic ball 472 is made of elastic rubber material;

[0047] During operation, the second elastic member is an elastic ball 472, which can effectively reduce the overall weight of the cleaning unit 4, while satisfying the supporting function of the elastic ball 472 on the support plate 473. The elastic ball 472 is made of elastic rubber material, which can further enhance the elastic force of the elastic ball 472, so that the brush 474 on the surface of the support plate 473 is in close contact with the inner wall surface of the feed hopper 1 to clean the inner wall surface of the feed hopper 1.

[0048] As an embodiment of the present invention, the surface of the support plate 473 is provided with uniformly arranged second air outlet holes 475; the second air outlet holes 475 are connected to the space inside the cavity 471;

[0049] During operation, evenly arranged second air outlet holes 475 are opened on the surface of the support plate 473, and the second air outlet holes 475 are connected to the space inside the cavity 471. When the brush 474 is close to the inner wall surface of the feed hopper 1, the reaction force generated drives the support plate 473 to move toward the top of the cavity 471, so that the gas in the space inside the cavity 471 flows out along the second air outlet holes 475, and the dust remaining on the surface of the brush 474 is cleaned, so as to prevent the dust adhering to the surface of the brush 474 from affecting the cleaning effect.

[0050] The specific operation process is as follows:

[0051] During the use of the automatic putty powder packaging machine, some putty powder will remain on the inner wall of the storage bin of the packaging machine. Since the storage bin is located at the top of the packaging machine, during daily cleaning and maintenance of the packaging machine equipment, due to the difference in diameter between the entrance of the storage bin and the outlet of the storage bin, the staff needs to use cleaning tools to repeatedly clean the inner wall surface of the storage bin, which not only reduces the cleaning efficiency but also increases the work intensity of the staff. The feed hopper 1 is designed to be square, and the feed port diameter at the top of the feed hopper 1 is larger than the outlet diameter at the bottom of the feed hopper 1, so that it is convenient for the staff to input putty powder into the feed hopper 1. A cleaning unit 4 is installed on the top surface of the inner wall of the feed hopper 1, and an electric push rod 2 is fixedly connected to the top surface of the cleaning unit 4. The electric push rod 2 is started, and the thrust of the electric push rod 2 is used to drive the cleaning unit 4 moves, since the cleaning unit 4 is provided with uniformly arranged first slide grooves 41 inside, a first cleaning plate 42 is slidably connected inside the first slide grooves 41, the length of the first cleaning plate 42 is equal to the length of the first slide grooves 41, the bottom of the first cleaning plate 42 is closely attached to the inner wall surface of the feed hopper 1, the first slide grooves 41 and the first cleaning plate 42 are fixedly connected by a first elastic member, and in the initial state, the first cleaning plate 42 utilizes the elastic force of the first elastic member to make the end of the first cleaning plate 42 away from one end of the first elastic member closely attached to the adjacent inner wall of the side wall where the cleaning unit is located in the feed hopper 1, and during the movement of the cleaning unit 4 toward the bottom of the feed hopper 1, the diameter of the inner wall of the feed hopper 1 gradually becomes shorter, and the first cleaning plate 42 gradually shrinks into the space inside the first slide grooves 41, so as to be able to perform a one-time cleaning of the inner wall of the feed hopper 1.

[0052] By opening a uniformly arranged second slide groove 45 inside the cleaning unit 4, a second cleaning plate 47 is slidably connected inside the second slide groove 45, and the second slide groove 45 and the second cleaning plate 47 are fixedly connected by a second spring 46, so that the second cleaning plate 47 can shrink and extend with the first cleaning plate 42, and a brush 474 is fixedly connected to the surface of one end of the second cleaning plate 47 close to the inner wall of the feed hopper 1. When the electric push rod 2 drives the cleaning unit 4 to move downward, it simultaneously drives the brush 474 at the bottom of the second cleaning plate 47 to move. The brush 474 can remove stubborn dust on the inner wall surface of the feed hopper 1 during the movement. In order to avoid dust residue at the bottom of the cleaning unit 4, a third cleaning plate 48 is fixedly connected to the bottom of the side wall between the first slide groove 41 and the second slide groove 45, so that the cleaning unit 4 synchronously drives the third cleaning plate 48 to move during the movement, thereby avoiding dust residue at the bottom of the cleaning unit 4.

[0053] By using the first elastic member as the first spring 43 , the elastic force of the first elastic member can be increased, so that the elastic force of the first elastic member can flexibly drive the first cleaning plate 42 to move in the first sliding groove 41 .

[0054] The cross-sections of the first cleaning plate 42 and the third cleaning plate 48 are both designed to be trapezoidal, so that when the first cleaning plate 42 and the third cleaning plate 48 clean the inner wall of the feed hopper 1, they can contact the stubborn dust remaining on the inner wall surface of the feed hopper 1 and play a role in shoveling away the dust, thereby effectively reducing the dust accumulation on the inner wall of the feed hopper 1.

[0055] By fixing and connecting uniformly arranged limit rods 11 on the upper surface of the feed hopper 1, the electric push rod 2 can be clamped between two adjacent limit rods 11, effectively avoiding deviation when installing the cleaning unit 4 and the electric push rod 2. By fixing and connecting uniformly arranged support rods 21 on the side of the electric push rod 2, the reaction force generated when the electric push rod 2 moves toward the bottom of the feed hopper 1 can be effectively avoided to cause the electric push rod 2 to shake, thereby ensuring the stability of the electric push rod 2. At the same time, it can also be easily disassembled, which is convenient for the later maintenance of the cleaning unit 4 and the parts inside the feed hopper 1.

[0056] The top of the cleaning unit 4 is fixedly connected to the air storage chamber 3, and the inner wall of the air storage chamber 3 is sealed and slidably connected with a sliding plate 31, which is fixedly connected to the sliding plate 31 through the end of the electric push rod 2, so that the electric push rod 2 drives the sliding plate 31 inside the air storage chamber 3 to move synchronously during the movement process, and the sliding plate 31 will compress the gas in the space of the air storage chamber 3 during the downward movement. Since the bottom of the air storage chamber 3 is provided with uniformly arranged exhaust holes 34, the exhaust holes 34 are connected to the air outlet groove 44 inside the cleaning unit 4, so that the compressed gas in the space of the air storage chamber 3 is discharged along the exhaust holes 34 and flows into The space inside the air outlet groove 44 is connected to the first air outlet hole through the air outlet groove 44, so that the gas in the space inside the air outlet groove 44 is ejected along the first air outlet hole, and the first air outlet hole is aligned with the inclined surface of the third cleaning plate 48, so that the gas ejected along the first air outlet hole can clean the surface of the third cleaning plate 48, effectively preventing dust from accumulating on the surface of the third cleaning plate 48 for a long time and affecting the cleaning effect of the third cleaning plate 48. After the electric push rod 2 pushes the sliding plate 31 to the bottom of the air storage chamber 3, the electric push rod 2 continues to extend, thereby driving the cleaning unit 4 to move toward the bottom of the feed hopper 1.

[0057] By fixing the evenly arranged air inlet holes 32 at the bottom of the air storage chamber 3, when the electric push rod 2 contracts, the electric push rod 2 drives the sliding plate 31 to move synchronously to the top of the air storage chamber 3. During the upward movement of the sliding plate 31, the air in the space outside the air storage chamber 3 is drawn into the space inside the air storage chamber 3 through the air inlet holes 32. By fixing the one-way valve 33 inside the air inlet holes 32, the gas in the air storage chamber 3 can only enter the space inside the air storage chamber 3 along the air inlet holes 32, and the air in the space inside the air storage chamber 3 cannot be discharged along the air inlet holes 32, thereby effectively preventing the gas in the space inside the air storage chamber 3 from flowing out along the air inlet holes 32, thereby providing sufficient gas power for cleaning the dust on the surface of the third cleaning plate 48.

[0058] The second cleaning plate 47 is provided with a cavity 471 inside, and a support plate 473 is sealed and slidably connected inside the cavity 471, so that the support plate 473 can slide up and down smoothly in the cavity 471, and the support plate 473 is fixedly connected to the inner wall of the cavity 471 by a uniformly arranged second elastic member, so that the second elastic member prevents the support plate 473 from directly contacting the inner wall of the top of the cavity 471, and the elastic force of the second elastic member is used to drive the support plate 473 to move toward the inner wall of the feed hopper 1, and a brush 474 is fixedly connected to one end of the support plate 473 close to the inner wall of the feed hopper 1, so that the brush 474 on the surface of the support plate 473 is always in close contact with the inner wall surface of the feed hopper 1, thereby further completing the cleaning of the inner wall surface of the feed hopper 1, and effectively avoiding the situation that the brush 474 does not contact the surface of the feed hopper 1 during the movement of the cleaning unit 4, thereby causing the brush 474 to be unable to clean the inner wall surface of the feed hopper 1.

[0059] By using the second elastic member as an elastic ball 472, the overall weight of the cleaning unit 4 can be effectively reduced while satisfying the supporting function of the elastic ball 472 on the support plate 473. By using the elastic ball 472 as an elastic rubber material, the elastic force of the elastic ball 472 can be further enhanced, so that the brush 474 on the surface of the support plate 473 is in close contact with the inner wall surface of the feed hopper 1 to clean the inner wall surface of the feed hopper 1.

[0060] By opening evenly arranged second air outlet holes 475 on the surface of the support plate 473, the second air outlet holes 475 are connected to the space inside the cavity 471. When the brush 474 is close to the inner wall surface of the feed hopper 1, the reaction force generated drives the support plate 473 to move toward the top of the cavity 471, so that the gas in the space inside the cavity 471 flows out along the second air outlet holes 475, and the dust remaining on the surface of the brush 474 is cleaned, so as to prevent the dust adhering to the surface of the brush 474 from affecting the cleaning effect.
