Description

Rotary printing machine with double heating plates for sequential hot printing and textile printing method

Technical Field

Thermal printing is one of the printing methods for textiles, and is mainly to place the textile to be printed on a base plate (printing plate), attach transfer paper or pyrograph paper to the textile, such as a manual high-pressure pyrograph machine disclosed in patent application 2015106137040, and thermally print the textile on the base plate by pressing down a heating plate.

The printing process includes transfer printing and direct printing. Transfer printing is a printing mode that transfer printing paper is placed on a textile such as a T-shirt, patterns on the transfer printing paper (transfer printing film) are transferred onto the textile through the action of hot pressing, and then the paper is removed; direct printing is a printing mode in which the pyrograph paper is placed on a textile such as a T-shirt and is directly attached to the textile under the action of hot pressing.

The time and temperature required for hot stamping of textiles made of different materials are different. For example, the temperature for carrying out heat transfer printing on chemical fiber fabrics or fabrics with low cotton content is 170-180 ℃ for 45-60s, the temperature for carrying out heat transfer printing on scarves is 120-140 ℃ for 10-20 s, the temperature for carrying out heat transfer printing on dark-color pure cotton fabrics is 170-180 ℃ for 10-15 s, and the temperature for carrying out heat transfer printing on light-color pure cotton fabrics is 190-200 ℃ for 20-30 s.

The same hot stamping device in the prior art can only meet the hot stamping of textiles made of one material in the same unit time, and the online simultaneous processing of the textiles made of different materials can only be carried out separately in different hot stamping production lines by adopting different hot stamping devices. Therefore, the device occupies a large area and consumes a lot of labor, branch management is needed, and the production efficiency needs to be improved.

In addition, when the prior art pyrograph machine carries out textile printing, because the hot pressing of hot plate has certain time in carrying out the heat seal on the bottom plate, be not enough to let operating personnel engage in other work in this operating time, operating personnel need keep on the station, waits for the heat seal time to finish, causes operating time to have the waste, and printing efficiency remains to be improved.

Therefore, by matching the characteristic that the first printing plate is higher than the second printing plate, namely the first printing plate and the second printing plate have height difference in the spatial height direction, the synchronous hot printing of the textiles with different hot printing temperatures and hot printing time can be realized in the unit time of one reciprocating motion of the second pressing device. The temperature difference can be adjusted by heating the temperatures of the first heating plate and the second heating plate, the control of the hot stamping time which is one of the key technical characteristics of the invention is realized by the intermittent linkage of the continuous reciprocating motion of the second pressing device and the reciprocating motion of the first pressing device, the hot stamping time of the first printing plate comprises the hot stamping time of the second printing plate and the static time of the first pressing device when the second pressing device presses and resets, and the hot stamping time of the second printing plate is integrated in the hot stamping time period of the first printing plate by the structure of the invention, thereby achieving the purpose that the same device can simultaneously hot stamp textiles meeting different process requirements in unit time and can integrate the time used by the hot stamping process with shorter hot stamping time in the time used by the hot stamping process with longer hot stamping time, thereby realizing the compactness of the industrial production device, The device saves the occupied area, realizes the integration of two production lines and improves the production efficiency.

Further, by adopting the structure of the invention, through the mutual mechanical cooperation of the first pressing device, the second pressing device, the intermittent transmission mechanism, the unidirectional rotation device and the rotating shaft, the sequential matching of the sequential hot stamping of the first heating plate and the second heating plate and the mutual exchange of the lifting motion of the hot stamping and the two printing plates for carrying out space displacement can be accurately realized, and the power driving source can be integrated on the second pressing device, so that the number pressure of the power driving source is reduced to the limit, and the operation and the control of an operator are greatly facilitated and the maintenance of a subsequent electric control link is facilitated.

Furthermore, the printing plate with the structure of the invention can improve the convenience of loading and unloading for operators by moving the first printing plate downwards to a position close to or flush with the second printing plate in the loading and unloading stage, and can ensure the stability of the first printing plate by utilizing the triple supporting functions of the contact of the bottom surfaces of the second elastic part, the third elastic part and the brake bar with the inner bottom surface of the limit open slot and the contact of the top surface of the brake bar with the inner top surface of the limit open slot in the hot printing stage.

Furthermore, by adopting the combined structure of the printing bearing plate and the blanking storage bin, when the combined structure is used, the printing bearing plate can be turned downwards to incline only by turning the waste turning plate upwards, the textile finished product can automatically fall into the first blanking through hole under the action of the incline, an operator only puts the waste paper removed from the textile finished product into the second blanking through hole, and classified blanking of the textile finished product and the waste paper can be realized. In addition, the waste material turning plate is turned upwards to the opening of the second discharging through hole so that the printing turning plate rotates downwards to an inclined mode, when the printing turning plate rotates downwards, the waste material turning plate is turned upwards to overcome the gravity of the waste material turning plate, compared with the mode that the waste material turning plate is turned downwards to the opening of the second discharging through hole so that the printing turning plate rotates downwards, larger external force is needed, and the position stability of the waste material printing turning plate in the horizontal state that the printing turning plate rotates upwards when the waste material turning plate is turned downwards to cover the second discharging through hole can be further improved.

Example 1

As shown in fig. 1 and 2, the present embodiment discloses a rotary printing machine for double-heating-plate sequential thermal printing, which comprises a printing plate 1, a heating plate, a first pressing device 31, an intermittent transmission mechanism 32, a second pressing device 33, a rotating shaft 41, and a unidirectional rotation device 5. The printing plates 1 are connected to a rotating shaft 41, and the rotating shaft 41 can rotate until the two printing plates 1 are opposite to the heating plate alternately.

The printing plate 1 comprises a first printing plate 11 and a second printing plate 12, wherein the height of the first printing plate 11 is higher than that of the second printing plate 12. The heating plate comprises a first heating plate 21 and a second heating plate 22, and when the printing plate 1 is opposite to the heating plate, the first heating plate 21 and the second heating plate 22 are respectively positioned above the first printing plate 11 and above the second printing plate 12. The first pressing device 31 is linked with the second pressing device 33 through the intermittent transmission mechanism 32, and the first pressing device 31 and the second pressing device 33 move to drive the first heating plate 21 and the second heating plate 22 to move respectively.

The pressing motion of the second pressing device 33 causes the pressing motion of the first pressing device 31 and the static of the first pressing device 31 to be sequentially performed, and the initial time when the first pressing device 31 is static occurs when the first heating plate 21 presses down to the initial time when the textile on the first printing plate 11 is hot-stamped.

The upward returning movement of the second depressing means 33 causes the first depressing means 31 to be stationary and the upward returning movement of the first depressing means 31 to be sequentially performed.

The first depressing device 31 is linked with the rotating shaft 41 through the unidirectional rotating device 5, so that when the first depressing device 31 is depressed, the rotating shaft 41 is stationary, and during the time period of the upward returning motion of the first depressing device 31, the rotating shaft 41 rotates. The angle of the single rotation of the rotating shaft 41 is an odd multiple of the angle between the first heating plate 21 and the second heating plate 22, such as 1 time, 3 times or 5 times.

When the rotary printing machine for the double-heating-plate sequential hot printing is used for hot printing two textiles (a first textile and a second textile) made of different materials, an external power supply is switched on, and two printing plates 1 are named as a main printing plate and a secondary printing plate respectively.

The first heating plate 21 and the second heating plate 22 in the initial state are opposite to the main printing plate, and the corresponding positions of the secondary printing plates are operation stations.

Two first textiles are respectively placed on a first printing plate 11 of a main printing plate and a first printing plate 11 of a secondary printing plate, two second textiles are respectively placed on a second printing plate 12 of the main printing plate and a second printing plate 12 of the secondary printing plate, and corresponding transfer printing paper or pyrograph paper is placed on each textile. The operator returns to the operating station. It is also possible to place only one first textile, one second textile and the corresponding transfer paper or pyrograph paper on each main printing plate.

Step one, the second pressing device 33 is pressed to drive the first heating plate 21 and the second heating plate 22 to be pressed downwards, and when the first heating plate 21 is pressed downwards to the initial time of carrying out hot printing on the first textile on the first printing plate 11 of the main printing plate, the first heating plate 21 stops moving. The second pressing device 33 continues to press down to drive the second heating plate 22 to press down to thermally print the second textile on the second printing plate 12 of the main printing plate.

Meanwhile, if no textile is placed on the secondary printing plate in the initial stage, at this time, the operator may place the next piece of the first textile, the second textile, and the corresponding transfer paper or pyrograph paper on the first printing plate 11 and the second printing plate 12 of the secondary printing plate at the operation station.

And step two, after the second textile on the second printing plate 12 of the main printing plate is subjected to hot printing, the second pressing device 33 moves upwards in a resetting manner to drive the second heating plate 22 to move upwards in a resetting manner, so that the first heating plate 21 is firstly stopped and then moves upwards in a resetting manner. During the time period of the upward return movement of the first heating plate 21, the rotating shaft 41 rotates to exchange the positions of the two printing plates 1.

And step three, the second pressing device 33 presses downwards to drive the first heating plate 21 and the second heating plate 22 to press downwards, and when the first heating plate 21 presses downwards to the initial time of carrying out hot printing on the first textile on the first printing plate 11 of the secondary printing plate, the first heating plate 21 stops moving. The second press-down device 33 continues to press down to drive the second heating plate 22 to press down to thermally print the textiles on the second printing plate 12 of the secondary printing plate. Meanwhile, the first textile and the second textile which are thermally printed on the first printing plate 11 and the second printing plate 12 of the main printing plate corresponding to the current operation station are taken out, and the next textile and the second textile which need to be printed and the corresponding transfer paper or the pyrograph paper are placed on the first printing plate 11 and the second printing plate 12 of the main printing plate.

And step four, after the textile hot printing on the second printing plate 12 of the secondary printing plate is finished, the second pressing device 33 resets upwards to drive the second heating plate 22 to reset upwards, so that the first heating plate 21 is stopped firstly and then resets upwards. During the time period of the upward return movement of the first heating plate 21, the rotation axis 41 is rotated to the position of the two printing plates 1 and then switched again.

And circulating the steps to realize the sequential flow hot stamping of a plurality of batches of textiles made of two different materials.

Compared with the prior art, the rotary printing machine adopting the double-heating-plate sequential hot printing for printing textiles has the following technical effects: the invention realizes the sequential matching of the first pressing device 31 and the second pressing device 33 through the intermittent transmission mechanism 32, so that the pressing motion of the second pressing device 33 causes the pressing motion of the first pressing device 31 and the static sequential proceeding of the first pressing device 31, and the static initial time of the first pressing device 31 occurs at the initial time when the first heating plate 21 presses to hot-stamp the textile on the first printing plate 11; the upward returning movement of the second depressing means 33 causes the first depressing means 31 to be stationary and the upward returning movement of the first depressing means 31 to be sequentially performed. Therefore, by matching the characteristic that the first printing plate 11 is higher than the second printing plate 12, namely, the first printing plate 11 and the second printing plate 12 have a height difference in the spatial height direction, the synchronous hot stamping of the textiles with different hot stamping temperatures and hot stamping time can be realized in the unit time of one reciprocating motion of the second pressing device 33. That is, the temperature difference can be adjusted by adjusting the heating temperature of the first heating plate 21 and the second heating plate 22, and the control of the hot stamping time, which is one of the key technical features of the present invention, is realized by the intermittent linkage of the reciprocating motion of the first depressing device 31 and the continuous reciprocating motion of the second depressing device 33, and the hot stamping time of the first printing plate 11 includes the hot stamping time of the second printing plate 12 and the time of the first depressing device 31 being stationary when the second depressing device 33 is depressed and reset, and by the structure of the present invention, the hot stamping time of the second printing plate 12 is integrated in the hot stamping time period of the first printing plate 11, so that the simultaneous hot stamping of textiles which can meet different process requirements in unit time by the same device, and the time of the hot stamping process in which the hot stamping time is short can be integrated in the time period of the hot stamping process in which the hot stamping time is long, therefore, the industrial production device is compact, the occupied area of the device is saved, the integration of two production lines is realized, and the production efficiency is improved. The invention realizes that the starting end and the terminating end of the moving tracks of the two printing plates 1 can be overlapped by ensuring that the moving tracks of the two printing plates are circular, which is a prerequisite condition for realizing the printing of the circulating water; because the first pressing device 31 and the rotating shaft 41 are linked through the unidirectional rotating device 5, when the first pressing device 31 moves downwards, the rotating shaft 41 is static, and the rotating shaft 41 rotates in the time period of the upward resetting movement of the first pressing device 31; when each heating plate carries out hot-stamping movement downwards, each printing plate 1 is relatively static and does not displace, so that the heating plates can accurately and stably carry out hot-stamping on textiles corresponding to the printing plates 1, and meanwhile, because the printing plates 1 are static at the moment, an operator can conveniently carry out feeding and discharging operations on the printing plates 1 which do not participate in hot-stamping, so that the utilization rate of a working gap of hot-stamping is greatly improved; after the printing is finished, after the heating plate is reset upwards to the proper position, in the two printing plates 1, the printing plate 1 which previously participates in hot printing can be transferred to a position which is opposite to an operator, namely an operation station, and the printing plate 1 which does not participate in hot printing can be transferred to a position which is opposite to the heating plate, so that the operator is ensured not to move the position all the time in the operation, the operator can always operate at the operation station where the operator is located, and the technical defects that in the prior art, the operator needs to switch back and forth at different operation stations, the labor is consumed, the operation is easy to be disordered, and the process flow is weak are overcome; by adopting the invention, operators can perform online operation in two links of feeding and discharging in a concentrated manner in most of time, compared with the prior art, the invention simplifies the operation link, reduces the occurrence of operation error rate and improves the industrial water flow; the operation of the heating plate lifting motion and the printing plate 1 moving are cooperated, so that the steps which should be sequentially operated are combined into one, and the processing time of industrial production is further saved.

Example 3

The present embodiment differs from the above embodiments in that: the lower parts of the first printing plate 11 and the second printing plate 12 are both connected with a blanking storage bin.

As shown in fig. 11 to 13, the top of each printing plate is provided with a first blanking through hole 111 and a second blanking through hole 112 which are vertically connected. The present embodiment is described with reference to the first printing plate 11, and the second printing plate 12 refers to the first printing plate 11.

The blanking storage bin comprises a waste storage bin 131 and a finished product storage bin 132. The first blanking through hole 111 is communicated with the finished product storage bin 132, and the second blanking through hole 112 is communicated with the waste storage bin 131. The first blanking through hole 111 and the second blanking through hole 112 are respectively matched with a printing turning plate 114 and a waste material turning plate 113 in a rotating way.

The first blanking through hole 111 is communicated with the second blanking through hole 112, and a transmission mechanism is arranged in the area where the first blanking through hole 111 is communicated with the second blanking through hole 112. The transmission mechanism is used for driving the waste material turning plate 113 and the printing turning plate 114 to be linked.

The waste material turning plate 113 is turned upwards to the opening of the second blanking through hole 112, so that the printing turning plate 114 rotates downwards to incline, and the printed textiles can fall from the printing turning plate 114 downwards into the finished product storage bin 132. The waste material turning plate 113 turns downwards to cover the second blanking through hole 112, so that the printing turning plate 114 rotates upwards and horizontally and covers the first blanking through hole 111.

When waste paper after transfer printing and textile finished products after printing are classified and discharged, the waste material turning plate 113 is turned upwards to the opening of the second discharging through hole 112, at the moment, the printing turning plate 114 rotates downwards to incline, and textile finished products on the printing turning plate 114 fall downwards into the first discharging through hole 111 and the finished product storage bin 132 under the action of the inclined guide of the printing turning plate 114; the used paper is thrown into the second blanking through-hole 112, and the used paper falls into the waste storage bin 131. Then, the waste material turning plate 113 is covered on the second blanking through hole 112, at this time, the printing turning plate 114 rotates upwards and horizontally and covers the first blanking through hole 111, and the printing plate 1 can be used for placing textiles again for next hot printing.

By adopting the combined structure of the printing bearing plate 1 and the blanking storage bin, when in use, the printing bearing turning plate 114 can be turned downwards to incline only by turning the waste material turning plate 113 upwards, the textile finished product can automatically fall into the first blanking through hole 111 under the action of the incline, an operator only puts the waste paper removed from the textile finished product into the second blanking through hole 112, and classified blanking of the textile finished product and the waste paper can be realized, two-step manual operation of turning the waste material turning plate 113 upwards and putting the waste paper in the whole operation is realized, the operation flow is further simplified, the respective storage of the textile finished product and the waste paper is realized, the waste material storage bin 131, the finished product storage bin 132 and the printing bearing plate 1 are integrated, and the compactness of the occupied space of a station is facilitated. In addition, the waste material turning plate 113 of the present invention turns upward to the opening of the second discharging through hole 112 so that the printing plate 114 rotates downward to incline, when the printing plate 114 rotates downward, the waste material turning plate 113 turns upward to overcome the gravity of the waste material turning plate 113, and compared with the waste material turning plate 113 turning downward to the opening of the second discharging through hole 112 so that the printing plate 114 rotates downward, a larger external force is required, and the position stability of the waste material printing plate 114 in the horizontal state that the printing plate 114 rotates upward when the waste material turning plate 113 turns downward to cover the second discharging through hole 112 can be further improved.

In some embodiments, the transmission includes a chain conveyor, a first reversing gear 1141, and a second reversing gear 1142. The chain type conveying device is used for driving the waste material turning plate 113 and the first reverse gear 1141 to be linked, the first reverse gear 1141 and the second reverse gear 1142 are meshed with each other, and the second reverse gear 1142 is linked with the printing turning plate 114.

The chain transmission device comprises a driving gear 11431, a driven gear 11432 and a chain 11433.

One end of the waste material turning plate 113 and the driving gear 11431 are sleeved on the fifth shaft 65, the driven gear 11432 and the first reverse gear 1141 are sleeved on the sixth shaft 66, the chain 11433 is sleeved on the driving gear 11431 and the driven gear 11432, and one end of the printing turning plate 114, namely the rotating matching end and the second reverse gear 1142 are sleeved on the seventh shaft 67. The fifth shaft 65 is in running fit with the inner wall of the second blanking through hole 112, and the sixth shaft 66 and the seventh shaft 67 are in running fit with the inner wall of the first blanking through hole 111 respectively.

In some embodiments, the two ends of the printing plate 114 are respectively a rotation coupling end and a free end, the rotation coupling end is rotatably coupled to one end of the first blanking through hole 111, the upper surface of the free end of the printing plate 114 is a first inclined surface gradually increasing in height toward the rotation coupling end, the inner bottom surface of the other end of the first blanking through hole 111 is a second inclined surface gradually decreasing in height toward the edge of the other end of the first blanking through hole 111, and when the printing plate 114 is horizontal, the first inclined surface and the second inclined surface are matched.

When the textile product is hot-stamped, the major or all of the area of which is attached to the printing plate 114, the printing plate 114 is flush with the surrounding area when closed and is in as seamless a contact as possible, so that when a textile product having a large area is hot-stamped, the textile product spreads out in the printing plate 1 at the level of the part of the printing plate 114 that falls on the surrounding area of the printing plate 114.

Therefore, by adopting the matching manner of the first inclined surface and the second inclined surface, on the basis of ensuring that the printing turning plate 114 can be turned upwards to be horizontal to the upper surface and is flush with the upper surface of the peripheral area, the seamless contact between the free end of the printing turning plate 114 and the edge of the first blanking through hole 111 can be ensured as far as possible.

In some embodiments, a magnetic limiting plate 1121 is disposed on the second discharging through hole 112, a first magnetic block is disposed on the lower surface of the waste material turning plate 113, and when the waste material turning plate 113 covers the second discharging through hole 112, the first magnetic block and the magnetic limiting plate 1121 attract each other.

In some embodiments, the first inclined surface and the second inclined surface are magnetic panels which are magnetically attracted to each other.

Through mutual attraction of the first magnetic block and the magnetic limiting plate 1121 and the function of matching the first inclined plane and the second inclined plane for mutual magnetic attraction, the position firmness of the waste turning plate 113 and the printing turning plate 114 in the covering state is further ensured, and the phenomenon that the waste turning plate 113 turns over automatically due to the fact that the heating plate is pressed downwards is further avoided.

In some embodiments, the projection of the first blanking through hole 111 in the vertical direction completely falls on the projection of the bottom surface of the heating plate in the vertical direction.

As shown in fig. 14 and 15, in some embodiments, a pedal transmission device is further included, and the pedal transmission device includes a foot plate 81, a linkage 82, a rotating rod 83, and a fourth elastic member 84. The foot plate 81 is in sliding fit with the blanking storage bin in the vertical direction, the upper end and the lower end of the linkage rod 82 are respectively hinged with the free end of the rotating rod 83 and the foot plate 81, and the connecting end of the rotating rod 83 is linked with the waste turning plate 113, namely the connecting end of the rotating rod 83 is sleeved on the fifth shaft 65. The fourth elastic member 84 is assembled such that the scrap flap 113 covers the second blanking through hole 112.

When the first blanking through hole 111 and the second blanking through hole 112 need to be opened, the foot plate 81 is stepped downwards, the foot plate 81 linearly moves downwards, the rotating rod 83 is driven to rotate through the transmission of the linkage rod 82, and the waste material turning plate 113 is driven to rotate upwards to the opening of the second blanking through hole 112.

Thus, the two steps of upwards turning the waste turning plate 113 and throwing in waste paper which need to be manually operated are further optimized, the operation of upwards turning the waste turning plate 113 in the first step is integrated at the foot of an operator, and the operation is matched with the step of throwing in waste paper in the second step, so that the coordination of the operation can be further improved. Thirdly, as the leg strength is far greater than the arm strength, the mode of opening the first and second blanking through holes 111 and 112 by foot can allow the fourth elastic member 84 to have a larger elastic deformation coefficient than the mode of manually opening the first and second blanking through holes 111 and 112, and further ensure that the position of the waste material turning plate 113 is firm when the waste material turning plate 113 is covered on the second blanking through hole 112 due to the assembly of the fourth elastic member 84.

In some embodiments, the fourth elastic member 84 is preferably a compression spring, and the upper and lower ends of the compression spring are respectively connected to the bottom of the foot plate 81 and the top of the spring support plate 883 connected to the blanking storage bin.

Of course, the fourth elastic member 84 may also be another elastic device or another spring in the prior art, such as a torsion spring of the printing plate 114, the torsion spring of the printing plate 114 may be sleeved on the seventh shaft 67, and both ends of the torsion spring are respectively connected to the printing plate 114 and the inner wall of the first blanking through hole 111.

In some embodiments, the first elastic member 54 is compressed when the material turning plate covers the second through hole 112.

In some embodiments, a locking lever 85 is rotatably coupled to the upper surface of foot plate 81. The spacing groove has still been seted up on unloading storage storehouse, and when waste material turned over 113 lids to close at second unloading through-hole 112, fifth elastic component 882 was assembled to cause the locking pole 85 spacing in the spacing groove and guarantee that the top surface of locking pole 85 contacts with the interior roof of spacing groove. The lock lever 85 can be rotated horizontally until it is rotated out of the limit groove.

Thus, when the waste material turning plate 113 covers the second discharging through hole 112, the top of the locking rod 85 is abutted against the top of the limiting groove, so as to further prevent the occurrence of driving the printing turning plate 114 to rotate downwards due to the pressing action of the heating plate on the printing plate 1. When the foot plate 81 needs to move downwards, an operator places feet on the locking rod 85, rotates the ankles, and drives the locking rod 85 to rotate out of the limiting groove under the action of friction force, so that the foot plate 81 can move.

In some embodiments, the upper surface of the foot plate 81 is a horizontal surface and the locking rod 85 is horizontal, when the heating plate presses down on the printing plate 1, because the bottom surface of the locking rod 85 is parallel to the inner bottom surface of the limiting groove, the printing plate 114 is vertical when the force is transferred to the force between the locking rod 85 and the limiting groove after being stressed, no horizontal component force exists, and the locking rod 85 is prevented from rotating automatically in this state.

In some embodiments, the fifth elastic member 882 may be a locking torsion spring, the locking rod 85 is sleeved on the locking shaft 881, and the locking shaft 881 is rotatably engaged with the foot plate 81. The locking torsion spring is sleeved on the locking shaft 881, and both ends of the locking torsion spring are respectively connected with the foot plate 81 and the locking rod 85. Of course, the fifth elastic member 882 may be another elastic device or another spring of the prior art.

In some embodiments, the shafts and the corresponding components of the present invention may be rotatably coupled to each other via bearings. The chain conveyor of the present invention may also be replaced with a prior art belt conveyor. Comprises a driving belt wheel, a driven belt wheel and a belt sleeved with the driving belt wheel and the driven belt wheel.

In some embodiments, a supporting disk 42 is further connected to the lower end of the rotating shaft 41, the bottom of the supporting disk 42 is in rotational contact with the base 92, the bottom of the rotating shaft 41 is in rotational fit with the base 92, and the bottom of the blanking storage bin is supported on the supporting disk 42.
