Description

Technical Field

[0001] The utility model relates to the technical field of rotary screen printing machines, in particular to a slurry bucket transportation system for a rotary screen printing machine. Background Art

[0002] With the development of the industry, various printing methods such as flat screen printing machines, planar rotary screen printing machines, inclined rotary screen printing machines, and digital printing machines have emerged successively. In a printing production line, regardless of the printing method, it involves three elements: a printing machine, a fabric, and a slurry. During operation, after the slurry bucket is transported and placed at the sizing position, the slurry in the slurry bucket is pumped into the rotary screen of the printing machine through a slurry pump. The rotary screen of the printing machine rolls on the fabric. During the rolling process of the rotary screen of the printing machine, the slurry in the rotary screen of the printing machine penetrates through the mesh holes on the rotary screen and is printed on the fabric to achieve printing. In the related research of printing, the research focus often concentrates on the optimization of the printing method or the improvement of printing efficiency. The transportation of the slurry bucket and the sizing of the slurry, as an integral part of printing, are often ignored. Most of the existing work of transporting and feeding the slurry bucket still adopts manual methods. The slurry bucket is transported manually. After removing the used slurry bucket at the sizing position and replacing it with a new one, the removed slurry bucket is then transported back. The entire operation has low efficiency and high manual labor intensity. When the slurry bucket is not transported and sized in time, it will affect the printing work. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a slurry bucket transportation system for a rotary screen printing machine, which can solve the problem of the conveying efficiency of the slurry bucket for the rotary screen printing machine.

[0004] The technical solution for realizing the purpose of the utility model is: A slurry bucket transportation system for a rotary screen printing machine includes a printing area and a beating area for adding slurry to the slurry bucket. The printing area is provided with a rotary screen printing machine and a sizing position. The slurry bucket for providing slurry to the rotary screen printing machine is placed at the sizing position. A conveying track passes through the printing area and the beating area. The sizing position and the slurry bucket at the sizing position are both located below the conveying track. The conveying track is suspended and is of a circular loop structure. A traveling trolley is arranged on the conveying track. An elevator is installed on the traveling trolley. The elevator includes an elevator body and a suspension rope. The suspension rope is suspended on the elevator body and can be lifted and lowered by the elevator body. A picking element is suspended on the suspension rope. A hanging part for cooperating with the picking element for hanging and picking is arranged on the slurry bucket.

[0005] Further, the bottom of the slurry bucket is a tapered bucket bottom that is wider at the top and narrower at the bottom. The lowest end of the bucket bottom has a slurry outlet. During operation, the slurry in the slurry bucket is pumped out of the slurry bucket through the slurry outlet. When the bucket bottom is tapered and the slurry outlet is arranged at the lowest end of the bucket bottom, the slurry in the slurry bucket can be pumped out more cleanly.

[0006] Furthermore, there is a sizing base at the sizing position. The sizing base is provided with a tapered mounting groove, and the taper of the tapered mounting groove is the same as that of the bottom of the barrel. A through hole is provided at the bottom of the tapered mounting groove. Each sizing position is correspondingly provided with a slurry delivery pipe. The first end of the slurry delivery pipe is communicated with the rotary screen printing machine, and the second end of the slurry delivery pipe is located directly below the through hole. The bottom of the barrel of the slurry barrel is placed in the tapered mounting groove on the sizing base, and the slurry outlet passes through the through hole and is butt-connected and communicated with the second end of the slurry delivery pipe. The sizing position in the present utility model can be the ground, can be a tabletop, or can have the sizing base. Preferably, the sizing position has the sizing base, and by placing the slurry barrel on the sizing base, the placement of the slurry barrel at the sizing position is realized. Specifically, the sizing base is provided with the tapered mounting groove, and the bottom of the barrel of the slurry barrel is a tapered barrel bottom that is wider at the top and narrower at the bottom. After the bottom of the barrel of the slurry barrel is placed in the tapered mounting groove on the sizing base, the tapered mounting groove can limit the slurry barrel. Under the limiting action of the tapered mounting groove, the vertically placed slurry barrel cannot move horizontally randomly and is not easily toppled, and the placement of the slurry barrel is more reliable. And after the second end of the slurry delivery pipe is located directly below the through hole, when the bottom of the barrel of the slurry barrel is placed in the tapered mounting groove on the sizing base, the slurry outlet can be directly communicated with the second end of the slurry delivery pipe. That is to say, one action can simultaneously realize the placement of the slurry barrel and the communication between the slurry outlet and the second end of the slurry delivery pipe. This setting makes the use convenient and the operation efficiency higher.

[0007] Furthermore, the slurry barrel transportation system of the rotary screen printing machine further includes a total control unit. A liquid level sensor is provided in the slurry barrel. The walking trolley and the liquid level sensor in the slurry barrel are respectively communicatively connected to the total control unit. The liquid level sensor is used to sense the liquid level information of the slurry in the slurry barrel and transmit the sensed liquid level information of the slurry in the slurry barrel to the total control unit. The total control unit is used to receive the liquid level information of the slurry in the slurry barrel transmitted by the liquid level sensor and to control the walking of the walking trolley. According to the liquid level information of the slurry in the slurry barrel transmitted by the liquid level sensor, the intelligent walking of the walking trolley can be realized under the control of the total control unit.

[0008] Further, the walking trolley includes a vehicle body and a trolley driving mechanism for driving the vehicle body to walk. A first control chip, a GPS positioning chip, and a first communication chip are arranged in the vehicle body. The trolley driving mechanism, the GPS positioning chip, and the first communication chip are respectively electrically connected to the first control chip. The first communication chip is communicatively connected to the total control unit. A second communication chip electrically connected to the liquid level sensor is further arranged in the slurry bucket. The second communication chip is located between the liquid level sensor and the total control unit and is used to realize the communication connection between the total control unit and the liquid level sensor. In the walking trolley, the trolley driving mechanism is used to drive the vehicle body to walk; the first control chip is the "brain" of the walking trolley; the GPS positioning chip positions the walking trolley and provides the position information of the walking trolley; the first communication chip plays a communication role; after the first communication chip is communicatively connected to the total control unit, the total control unit can communicate with the first control chip. After the GPS positioning chip obtains the position information of the walking trolley, the position information can be transmitted by the first control chip to the total control unit via the first communication chip. The total control unit can also send a control signal to the first control chip via the first communication chip. The first control chip controls the trolley driving mechanism according to the control signal sent by the total control unit, and then controls the walking of the walking trolley. In the slurry bucket, the liquid level sensor is used to sense the liquid level information of the slurry in the slurry bucket; the second communication chip plays a communication role; after the second communication chip is communicatively connected to the total control unit, the liquid level information of the slurry in the slurry bucket sensed by the liquid level sensor can be transmitted to the total control unit via the second communication chip. During operation, the liquid level sensor continuously senses the liquid level information of the slurry in the slurry bucket and transmits the sensed liquid level information of the slurry in the slurry bucket to the total control unit via the second communication chip; the GPS positioning chip continuously positions the position information of the walking trolley, and the position information is continuously transmitted by the first control chip to the total control unit via the first communication chip; when the liquid level information of the slurry in the slurry bucket indicates that the slurry in the slurry bucket at the sizing position is used up, the total control unit sends a control signal, and the control signal is transmitted to the first control chip via the first communication chip. The first control chip controls the trolley driving mechanism according to the control signal sent by the total control unit, so that the walking trolley walks to the sizing position where the slurry in the slurry bucket is used up, so that the lifting rope of the elevator can first descend under the drive of the elevator body. After the picking element picks up the hanging part of the slurry bucket, it then ascends to lift the slurry bucket with the used-up slurry at the sizing position. Then, under the control of the total control unit, the walking trolley transports the slurry bucket with the used-up slurry to the beating area for slurry addition.Meanwhile, the total control unit can also control the walking trolley. After the elevator on the walking trolley lifts the slurry bucket filled with slurry, it transports the slurry bucket filled with slurry to the sizing position to be sized. With the above arrangement of the present utility model, when the slurry in the slurry bucket is used up and the slurry bucket with used-up slurry needs to be transported back to the beating area, or when there is no slurry bucket at the sizing position and the slurry bucket filled with slurry at the beating area needs to be transported to the sizing position, according to the liquid level information of the slurry in the slurry bucket sensed by the liquid level sensor and the position information of the walking trolley located in real time by the GPS positioning chip, the total control unit controls the walking trolley, enabling the intelligent movement of the walking trolley, and then completing the automatic operations of the walking trolley transporting the empty slurry bucket to the beating area and transporting the slurry bucket filled with slurry from the beating area to the sizing position, greatly improving the intelligence of the slurry bucket transportation system of the rotary screen printing machine of the present utility model.

[0009] Further, the elevator is an electric hoist. The elevator body can be a lead screw, a telescopic rod, a lifting chain, an electric hoist, etc. Compared with others, the electric hoist itself has a rope structure that can be used as the lifting rope. As the combination of the elevator body and the lifting rope, it can be directly used as the elevator, and it is more convenient to use.

[0010] Further, the elevator further includes a third control chip and a third communication chip. The elevator body and the third communication chip are respectively electrically connected to the third control chip, and the third communication chip is communicatively connected to the total control unit. During operation, the total control unit can send a control signal to the third communication chip, and the third communication chip transports the control signal received from the total control unit to the third control chip. According to the control signal sent by the total control unit, the third control chip controls the movement of the elevator body, realizing the intelligent lifting of the elevator. This arrangement greatly improves the intelligence of the slurry bucket transportation system of the rotary screen printing machine of the present utility model.

[0011] Further, the picking element is a hook. When the picking element is a hook, the picking element hooks onto the hanging and picking part of the slurry bucket. The hook structure is simple, the cost is low, and the firmness is good when hooked ring by ring.

[0012] Further, the fetching element is a mechanical claw, which includes a mechanically grippable claw body that can be opened and closed, and a mechanical claw driving mechanism for driving the opening and closing of the mechanically grippable claw body. The fetching element further includes a fourth control chip and a fourth communication chip. Both the mechanical claw driving mechanism and the fourth communication chip are electrically connected to the fourth control chip respectively, and the fourth communication chip is communicatively connected to the total control unit. When the fetching element is a mechanical claw, the mechanically grippable claw body grabs the pulp bucket below the hanging and fetching portion, and the hanging and fetching portion limits the grabbing of the mechanically grippable claw body, so that the mechanically grippable claw body can grab firmly. The above setting of the mechanical claw facilitates automatic fetching. Specifically, during operation, the total control unit can send a control signal to the fourth communication chip, and the fourth communication chip conveys the received control signal sent by the total control unit to the fourth control chip. According to the control signal sent by the total control unit, the fourth control chip controls the mechanical claw driving mechanism to act, realizing the intelligent opening and closing of the mechanically grippable claw body. This setting greatly improves the intelligence of the pulp bucket transportation system of the rotary screen printing machine of the present utility model.

[0013] Further, the hanging and fetching portion is a ring body installed on the top of the pulp bucket. While the ring body structure facilitates the hanging and fetching of the fetching element, it can also make the circumferential mass distribution of the pulp bucket more uniform, and the balance during hanging and fetching is better.

[0014] Further, there are several rotary screen printing machines in the printing area, and the several rotary screen printing machines are arranged in a row. The conveying track includes several branches and a return section. Both ends of each branch are respectively connected to both ends of the return section to form a loop. The number of branches is the same as the number of rotary screen printing machines, and the branches correspond to the rotary screen printing machines one by one. The branches are directly above the sizing positions of the corresponding rotary screen printing machines. Under this setting, all the branches share the same return section, and the conveying route of the conveying track is set more concentratedly.

[0015] The slurry bucket transportation system of the rotary screen printing machine of the present utility model is provided with the conveying track passing through the printing area and the beating area, and the traveling trolley is arranged on the conveying track, so that the traveling trolley running along the conveying track can shuttle between the printing area and the beating area, providing a moving tool for the transportation of the slurry bucket between the printing area and the beating area; at the same time, the elevator with the fetching element is installed on the traveling trolley, so that under the operation of the elevator, the fetching element for hanging and fetching the slurry bucket can be lifted and lowered, and the fetching and placing of the slurry bucket are completed in the vertical direction. That is to say, the slurry bucket transportation system of the rotary screen printing machine of the present utility model can not only realize the moving transportation of the slurry bucket between the printing area and the beating area, but also the liftable elevator completes the automatic lifting and lowering of the slurry bucket before and after transporting the slurry bucket. The whole transportation process, including the lifting, conveying and lowering of the slurry bucket, does not require manual participation, manual transportation, manual lifting or lowering, greatly saving the manual labor and improving the conveying efficiency.

[0016] For the slurry bucket transportation system of the rotary screen printing machine of the present utility model, the conveying track is suspended. On the one hand, the suspended conveying track is located above the sizing position. The conveying path of the slurry bucket can be higher than the sizing position, rather than lower than the sizing position or arranged horizontally with the sizing position. After the conveying path of the slurry bucket is higher than the sizing position, the slurry bucket conveyed to the sizing position is located above the sizing position, rather than below the sizing position or on one side of the sizing position. Compared with the structure where the conveying track of the slurry bucket is arranged below the sizing position or horizontally with the sizing position on the ground, after the slurry bucket of the present utility model is conveyed to the sizing position, the slurry bucket located above the sizing position can complete the seating and lifting on the sizing position through lifting and moving, without the need for manual lifting of the slurry bucket to the sizing position or moving it away from the sizing position, and the transportation operation of the slurry bucket is more time-saving and labor-saving; on the other hand, compared with the floor-mounted setting, the suspended conveying track can reduce the floor area, greatly improving the utilization rate of the workshop, and at the same time, it does not affect or hinder the work of the ground operators.

[0017] Moreover, the conveying track is of a circular structure. While the circular conveying track completes the cyclic conveying, the path for transporting the pulp bucket from the printing area to the beating area is different from the path for transporting the pulp bucket from the beating area to the printing area. The movement of the walking trolley on the conveying track in the direction from the printing area to the beating area is separated from the movement in the direction from the beating area to the printing area, thus there is no problem of occupying the road. There is no need to wait for the movement from the beating area to the printing area to be completed before the movement from the printing area to the beating area can be carried out, and similarly, there is no need to wait for the movement from the printing area to the beating area to be completed before the movement from the beating area to the printing area can be carried out. The movement of the walking trolley on the conveying track is more free, and the conveying efficiency is also higher.

[0018] In addition, for the pulp bucket transportation system of the rotary screen printing machine of the present invention, the elevator includes the elevator body and the suspension rope. The fetching element for hanging and fetching the pulp bucket is hoisted on the suspension rope. When the suspension rope hoists and transports the pulp bucket, on the one hand, the fetching element and the pulp bucket on the fetching element are relatively flexible. When slightly applying force to pull the suspension rope or the pulp bucket, the pulp bucket on the suspension rope can be moved and displaced. This setting, especially when the pulp bucket hoisted on the suspension rope is placed in position at the sizing position, even if the stopping position of the walking trolley is inaccurate and the pulp bucket hoisted on the suspension rope cannot be accurately aligned with the sizing position, the position of the pulp bucket can be adjusted by pulling the suspension rope to quickly and accurately align the pulp bucket hoisted on the suspension rope with the sizing position. The flexibility and convenience of this operation greatly reduce the requirement for the accuracy of the stopping position of the walking trolley. The walking trolley can meet the operation requirements without too high running control precision, greatly reducing the control burden of the movement of the walking trolley. On the other hand, the suspension rope is soft and has strong deformation ability. When it is hoisted and moved, even if accidentally collided by the operator below, it will not cause injury. At the same time, when the walking trolley is empty, the suspension rope can be wound up for convenient storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will make a detailed description of the specific embodiments of the slurry bucket transportation system of the rotary screen printing machine of the utility model with reference to the accompanying drawings:

[0030] As Figure 1 to Figure 4 and Figure 6 and Figure 7 As shown, a slurry bucket transportation system for a rotary screen printing machine includes a printing area 10 and a beating area 20 for adding slurry to the slurry bucket 3. The printing area 10 is provided with a rotary screen printing machine 1 and a slurry feeding position 2. The slurry bucket 3 that provides slurry for the rotary screen printing machine 1 is placed on the slurry feeding position 2. A conveying track 4 passes through the printing area 10 and the beating area 20. The slurry feeding position 2 and the slurry bucket 3 on the slurry feeding position 2 are both located below the conveying track 4. The conveying track 4 is suspended and is a circular loop structure. A walking trolley 5 is provided on the conveying track 4. An elevator 6 is installed on the walking trolley 5. The elevator 6 includes an elevator body 61 and a suspension rope 62. The suspension rope 62 is suspended on the elevator body 61 and can be lifted and lowered by the elevator body 61. A picking element 63 is suspended on the suspension rope 62. A hanging part 31 for cooperating with the picking element 63 to hang and pick is provided on the slurry bucket 3.

[0031] The slurry bucket transportation system of the rotary screen printing machine of the present utility model. In the printing area 10, there are provided the rotary screen printing machine 1 and the slurry feeding position 2. Among them, the slurry feeding position 2 is used for placing the slurry bucket 3. The slurry bucket 3 serves as a container for holding the slurry required for printing. The slurry bucket 3 filled with slurry placed on the slurry feeding position 2 is connected to the rotary screen printing machine 1 through a slurry conveying pipe. After connection, under the action of a slurry pump, the slurry in the slurry bucket 3 on the slurry feeding position 2 is conveyed to the rotary screen printing machine 1 to provide slurry for the printing work of the rotary screen printing machine 1. The rotary screen printing machine 1, as a printing device, during the rolling process, squeezes and prints the slurry onto the fabric through a squeegee to achieve printing on the fabric. A rotary screen printing machine usually has several rotary screens. Correspondingly, the slurry feeding positions 2 for providing slurry for several rotary screens usually also have several.

[0032] The slurry bucket transportation system of the rotary screen printing machine of the present utility model. The beating area 20 serves as a slurry adding area, and in this area, it is mainly used for filling and adding slurry into the slurry bucket 3. In addition, if the slurry bucket 3 needs to be cleaned, it can also be cleaned in the beating area 20 before filling the slurry into the slurry bucket 3.

[0033] The slurry bucket transportation system of the rotary screen printing machine of the present utility model. The conveying track 4 is suspended and has an annular structure. The installation height of the suspended conveying track 4 is higher than the installation height of the slurry feeding position 2 and the slurry bucket 3 on the slurry feeding position 2. The slurry feeding position 2 is located directly below the conveying track 4. The installation height of the conveying track 4 is flexible and can be set as needed. Preferably, the installation height of the conveying track 4 is limited so as not to affect the normal walking and work of the operator.

[0034] The slurry bucket transportation system of the rotary screen printing machine of the present utility model. The walking trolley 5 is installed on the conveying track 4 with limited movement and can walk and move along the conveying track 4. The walking trolley 5 walking and moving along the conveying track 4 is used as a transportation tool for the slurry bucket 3. In the elevator 6, the elevator body 61 is the power main body for lifting. The suspension rope 62 is suspended on the elevator body 61 and can be lifted by the elevator body 61. After the picking element 63 on the suspension rope 62 picks up the picking part 31 of the slurry bucket 3, under the driving action of the elevator body 61, the lifting suspension rope 62 can pick up the slurry bucket 3 to make the slurry bucket 3 also lift.

[0035] The slurry bucket transportation system of the rotary screen printing machine of the utility model, during operation, slurries are filled into the slurry bucket 3 at the pulping area 20. After the slurry bucket 3 at the pulping area 20 is filled with slurries, the traveling trolley 5 on the conveying track 4 runs to the pulping area 20. The elevator body 61 of the elevator 6 runs, driving the lifting rope 62 and the lifting element 63 thereon to descend. After the lifting element 63 hooks the hanging part 31 of the slurry bucket 3, the elevator body 61 drives the lifting rope 62 and the slurry bucket 3 to rise. After the slurry bucket 3 is lifted, the traveling trolley 5 runs to transport the slurry bucket 3 above the sizing position 2 in the printing area 10. Then, the elevator body 61 of the elevator 6 runs, driving the lifting rope 62 and the slurry bucket 3 hung thereon to descend until the slurry bucket 3 filled with slurries is placed on the sizing position 2; the slurry bucket 3 placed on the sizing position 2 supplies slurries to the rotary screen printing machine 1, enabling the rotary screen printing machine 1 to perform printing work.

[0036] The slurry bucket transportation system of the rotary screen printing machine of the utility model, as the rotary screen printing machine 1 in the printing area 10 operates, after the slurries in the slurry bucket 3 on the sizing position 2 are used up, the traveling trolley 5 on the conveying track 4 runs above the sizing position 2 in the printing area 10. After that, the elevator body 61 of the elevator 6 runs, driving the lifting rope 62 and the lifting element 63 thereon to descend. After the lifting element 63 hooks the hanging part 31 of the slurry bucket 3 with used-up slurries on the sizing position 2, the elevator body 61 drives the lifting rope 62 and the slurry bucket 3 to rise. After the slurry bucket 3 is lifted, the traveling trolley 5 runs to transport the slurry bucket 3 to the pulping area 20. Then, the elevator body 61 of the elevator 6 runs, driving the lifting rope 62 and the slurry bucket 3 hung thereon to descend. After the slurry bucket 3 is put down, the slurry bucket 3 is filled with additional slurries at the pulping area 20. In this way, under the operation of the traveling trolley 5 on the conveying track 4, the lifting and transportation of the slurry bucket 3 between the printing area 10 and the pulping area 20 are completed.

[0037] The slurry bucket transportation system of the rotary screen printing machine of the present utility model is provided with the conveying track 4 passing through the printing area 10 and the beating area 20, and the traveling trolley 5 is arranged on the conveying track 4, so that the traveling trolley 5 running along the conveying track 4 can shuttle between the printing area 10 and the beating area 20, providing a moving tool for the transportation of the slurry bucket 3 between the printing area 10 and the beating area 20; at the same time, by installing the elevator 6 with the fetching element 63 on the traveling trolley 5, under the operation of the elevator 6, the fetching element 63 for hanging and fetching the slurry bucket 3 can be lifted and lowered, and the fetching and placing of the slurry bucket 3 are completed in the vertical direction. That is to say, the slurry bucket transportation system of the rotary screen printing machine of the present utility model can not only realize the moving transportation of the slurry bucket 3 between the printing area 10 and the beating area 20, but also before and after transporting the slurry bucket 3, the liftable elevator 6 also completes the automatic lifting and lowering of the slurry bucket 3. The whole transportation process, including the lifting, transportation and lowering of the slurry bucket 3, does not require manual participation, manual transportation, manual lifting or lowering, greatly saving the manual labor amount and improving the transportation efficiency.

[0038] For the slurry bucket transportation system of the rotary screen printing machine of the present utility model, the conveying track 4 is suspended. On the one hand, the suspended conveying track 4 is located above the sizing position 2. The conveying path of the slurry bucket 3 can be higher than the sizing position 2, rather than lower than the sizing position 2 or arranged horizontally with the sizing position 2. After the conveying path of the slurry bucket 3 is higher than the sizing position 2, the slurry bucket 3 conveyed to the sizing position 2 is located above the sizing position 2, rather than below the sizing position 2 or on one side of the sizing position 2. Compared with the structure where the conveying track 4 is arranged on the ground and the conveying path of the slurry bucket 3 is located below the sizing position 2 or arranged horizontally with the sizing position 2, after the slurry bucket 3 of the present utility model is conveyed to the sizing position 2, the slurry bucket 3 located above the sizing position 2 can complete the seating and lifting on the sizing position 2 through lifting and moving, without the need for manual lifting of the slurry bucket 3 to the sizing position 2 or moving it away from the sizing position 2, and the transportation operation of the slurry bucket 3 is more time-saving and labor-saving; on the other hand, compared with the floor-mounted setting, the suspended conveying track 4 can reduce the floor area, greatly improving the utilization rate of the factory building while not affecting or hindering the work of ground operators.

[0039] Moreover, the conveying track 4 is of a circular structure. While the circular conveying track 4 completes circular conveying, the path for transporting the pulp bucket 3 from the printing area 10 to the beating area 20 is different from the path for transporting it from the beating area 20 to the printing area 10. The movement of the walking trolley 5 on the conveying track 4 in the direction from the printing area 10 to the beating area 20 is separated from its movement in the direction from the beating area 20 to the printing area 10, without the problem of occupying the road. There is no need to wait for the movement from the beating area 20 to the printing area 10 to be completed before the movement from the printing area 10 to the beating area 20 can be carried out, and similarly, there is no need to wait for the movement from the printing area 10 to the beating area 20 to be completed before the movement from the beating area 20 to the printing area 10 can be carried out. The movement of the walking trolley 5 on the conveying track 4 is more flexible, and the conveying efficiency is also higher.

[0040] In addition, for the pulp bucket transportation system of the rotary screen printing machine of the present invention, the elevator 6 includes the elevator body 61 and the suspension rope 62. The object-taking element 63 for hanging and taking the pulp bucket 3 is hoisted on the suspension rope 62. When the suspension rope 62 hoists the pulp bucket 3, on the one hand, the object-taking element 63 and the pulp bucket 3 on the object-taking element 63 are relatively flexible. With a slight force applied to pull the suspension rope 62 or the pulp bucket 3, the pulp bucket 3 on the suspension rope 62 can be moved and displaced. This setting, especially when the pulp bucket 3 hoisted on the suspension rope 62 is placed in position at the sizing position 2, even if the stopping position of the walking trolley 5 is inaccurate and the pulp bucket 3 hoisted on the suspension rope 62 cannot be accurately aligned with the sizing position 2, the position of the pulp bucket 3 can be adjusted by pulling the suspension rope 62 to quickly and accurately align the pulp bucket 3 hoisted on the suspension rope 62 with the sizing position 2. The flexibility and convenience of this operation greatly reduce the requirement for the stopping accuracy of the walking trolley 5. The walking trolley 5 can meet the operation requirements without too high running control accuracy, greatly reducing the control burden of the movement of the walking trolley 5. On the other hand, the suspension rope 62 is soft and has strong deformation ability. When it is hoisted and moved, even if it is accidentally collided by the operator below, it will not cause injury. At the same time, when the walking trolley 5 is empty, the suspension rope 62 can be rolled up for convenient storage.

[0041] The pulp bucket transportation system of the rotary screen printing machine of the present invention, preferably, as Figure 5 and Figure 6As shown, the bottom 32 of the slurry barrel 3 is tapered, wider at the top and narrower at the bottom. A slurry outlet 33 is provided at the bottom of the barrel 32. During operation, the slurry in the slurry barrel 3 is pumped out of the barrel 3 through the slurry outlet 33. The tapered bottom and the slurry outlet 33 at the bottom of the barrel 32 allow the slurry in the barrel 3 to be pumped out more cleanly.
