In the prior art, the cake pressing module 101 generally adopts a transmission rod (screw rod mechanism) moving along the vertical direction to drive the baking tray to move up and down, so that the axial space occupied by the cake pressing module 101 is easily increased in the operation process, and the cake making machine 100 cannot be miniaturized.

The present invention proposes a cookie pressing module 101.

Referring to fig. 1 to 3, in the embodiment of the present invention, the cookie module 101 includes a fixed bracket 10, a motor 20, a crank block mechanism 40, and a first baking tray 60; the motor 20 is arranged on the fixed bracket 10; the crank block mechanism 40 is in transmission connection with the motor 20 and is rotationally connected to the fixed bracket 10; the first baking tray 60 is in transmission connection with the crank-slider mechanism 40, so that the first baking tray 60 is driven by the motor 20 to move up and down through the crank-slider mechanism 40, and the first baking tray 60 is provided with a material waiting station and a cake pressing station, wherein the material waiting station and the cake pressing station are arranged at intervals along the moving direction of the first baking tray 60. Therefore, the structure of each part in the cake pressing module 101 is more compact, and in the operation process, the crank block mechanism 40 does not need to increase the occupied axial space due to the movement of the first baking tray 60, which is beneficial to saving the occupied axial space of the cake pressing module 101, and further reduces the overall thickness of the cake making machine 100, and makes the cake making machine light and thin.

The cake baking machine 100 further comprises a second baking tray 61, the first baking tray 60 is provided with a material waiting station and a cake pressing station, the material waiting station and the cake pressing station are arranged at intervals along the moving direction of the first baking tray 60, so that dough in the previous process enters the cake pressing module 101, the cake pressing module 101 can process the dough, the material waiting station is a position, away from the second baking tray 61, of the first baking tray 60 as far as possible, namely, the distance between the first baking tray 60 and the second baking tray 61 is at least greater than the thickness of the dough in the previous process in the axial direction, and the cake pressing station is a position, close to the first baking tray 60, and mutually abutted with the second baking tray 61.

As shown in fig. 1 to 2, when the crank-slider mechanism 40 is located above the first baking tray 60, the waiting station is located above the cake pressing station, the first baking tray 60 is located above the second baking tray 61, and then the crank-slider mechanism 40 drives the first baking tray 60 to move downwards, so that the first baking tray 60 moves from the waiting station to the cake pressing station, and the dough in the previous process is clamped between the first baking tray 60 and the second baking tray 61, so that the dough is pressed into a cake with a specified thickness, and then the cake is heated and baked, so that fresh and delicious cooked wheaten food is produced.

The cake making machine 100 further comprises a base 11, the second baking tray 61 is arranged on the base 11, and the fixing support 10 is fixed on the base 11 in a bolting, embedding, clamping or other mode to assemble the cake pressing module 101 to the base 11, wherein the fixing support 10 can isolate the cake pressing module 101 from at least part of functional modules, so that mutual interference between working procedures is reduced, and cake making efficiency and cake making identity of the cake making machine 100 are improved.

In addition, in this process, the first baking tray 60 is worn and moves up and down in the fixed support 10 under the driving action of the slider-crank mechanism 40, that is, a space for the slider-crank mechanism 40 to move and a moving space adapted to the first baking tray 60 are provided in the fixed support 10, so that on one hand, the first baking tray 60 and the slider-crank mechanism 40 are concentrated, the first baking tray 60 and the slider-crank mechanism 40 are convenient to be compact in structure, and effective driving of the slider-crank mechanism 40 is ensured, on the other hand, not only can rotation supporting points be provided for rotation of the slider-crank mechanism 40, but also the slider-crank mechanism 40 can reliably operate, and the moving direction of the first baking tray 60 can be further restrained, and the moving stability of the first baking tray 60 is improved. In addition, the reaction force of the second baking tray 61 to the first baking tray 60 and the reaction force of the first baking tray 60 to the crank block mechanism 40 can be dispersed, so that the service lives of the first baking tray 60 and the crank block mechanism 40 can be prolonged, and the use safety and the use reliability of the cake pressing module 101 can be improved.

Because the first baking tray 60 needs to move up and down, the motor 20 is in transmission connection with the slider-crank mechanism 40, and the slider-crank mechanism 40 can swing reciprocally around the fixed bracket 10 through forward rotation and reverse rotation of the motor 20, wherein the motor 20 and the slider-crank mechanism 40 can be driven to push or press by meshing transmission teeth, jacking mechanism jacking and cam rotation, so as to realize the reciprocating swing of the slider-crank mechanism 40.

The reciprocating swing of the crank block mechanism 40 is converted into the up-down linear motion of the first baking tray 60, so that on one hand, the space occupied by the cake pressing module 101 in the axial direction of the first baking tray 60 in the process can be reduced, and the cake pressing module 101 is thinned; on the other hand, reliable driving of the motor 20 and stable operation of the first bakeware 60 are facilitated. The axial space specifically refers to a space in the axial direction of the first pan 60.

Similarly, when the crank-slider mechanism 40 is located below the first baking tray 60, the cake pressing module 101 can process dough as well, that is, by setting the waiting station below the cake pressing station, the first baking tray 60 is located below the second baking tray 61, and then the crank-slider mechanism 40 drives the first baking tray 60 to move upwards, so that the first baking tray 60 moves from the waiting station to the cake pressing station, the dough in the previous process is clamped between the first baking tray 60 and the second baking tray 61, so that the dough is pressed into a cake with a specified thickness, and then the cake is heated and baked, so that fresh and delicious wheaten food is produced.

According to the technical scheme, the motor 20 and the crank block mechanism 40 are adopted to drive in a matched manner, so that the rotation and swing of the crank block mechanism 40 are converted into the up-and-down reciprocating motion of the first baking tray 60, wherein the crank block mechanism 40 and the first baking tray 60 are intensively arranged on the fixed support 10, on one hand, the first baking tray 60 and the crank block mechanism 40 are convenient to compact in structure, the effective driving of the crank block mechanism 40 and the stable operation of the first baking tray 60 are ensured, meanwhile, the occupied space of the cake pressing module 101 in the axis direction of the first baking tray 60 in the process can be reduced, and the cake pressing module 101 is thinned; on the other hand, the fixed support 10 is used for providing a rotating fulcrum for the rotation of the crank block mechanism 40, and space constraint is provided for the switching of the material waiting station and the cake pressing station of the first baking tray 60 through the fixed support 10, so that the reliable driving of the crank block mechanism 40 is further ensured, the movement direction of the first baking tray 60 is constrained, and the movement stability of the first baking tray 60 is improved.

The specific structure of the cookie pressing module 101 of the present application will be described below by an embodiment in which the waiting station is located above the cookie pressing station and the first baking tray 60 is located above the second baking tray 61.

Referring to fig. 1 to 3, in an embodiment, the slider-crank mechanism 40 includes a swinging member 41 and an abutting rod 42, wherein the swinging member 41 is rotatably connected to the fixed bracket 10, and one end is in driving connection with the motor 20, the other end is rotatably connected to one end of the abutting rod 42, and the other end of the abutting rod 42 is rotatably connected to the first baking tray 60. Therefore, the pushing rod 42 can rotate along with the swinging member 41 through the rotation and swinging, and then the first baking tray 60 is driven to move up and down under the constraint of the fixed bracket 10, so that the switching of the first baking tray 60 between the material waiting station and the cake pressing station is realized.

Specifically, the swinging member 41 may have a disc-shaped structure, a rod-shaped structure, and the like, and opposite ends thereof are respectively connected to the motor 20 and the pushing rod 42, and the areas other than the two ends are rotatably connected to the fixed bracket 10, so that the swinging direction and the swinging speed of the swinging member 41 can be controlled by applying force to the swinging member 41 by the driving force of the motor 20 using the lever principle, thereby controlling the movement of the first baking tray 60. Of course, in other embodiments, the swinging member 41 may also be a crankshaft structure, an eccentric structure, etc., and the swinging member 41 can be converted into the linear motion of the first baking tray 60.

The swinging member 41 can be erected on the fixed support 10 through the rotating shaft, so that the force can be conveniently and evenly dispersed to the fixed support 10, the stable swinging of the swinging member 41 is facilitated, and the fixed support 10 is safe to use. Similarly, the swinging member 41 and the pushing rod 42 are connected through the rotating shaft, so that the end part of the pushing rod 42 is conveniently and uniformly stressed, and the structural stability of the pushing rod 42 and the driving effectiveness of the swinging member 41 are improved.

Referring to fig. 3, in one embodiment, the swing member 41 includes a swing link 411 and a sector member 412, the swing link 411 is rotatably connected to the fixed bracket 10, and one end is rotatably connected to the push rod 42, and the other end is connected to the sector member 412, and the sector member 412 is drivingly connected to the motor 20. By this arrangement, the reliable driving of the swinging member 41 can be ensured while saving the manufacturing cost.

Specifically, the fan-shaped piece 412 is configured such that the motor 20 drives the swinging piece 41 to rotate and swing according to the specific structure of the fan-shaped piece 412, and it can be understood that the fan-shaped piece 412 has a first end and a second end, which correspond to the material waiting station and the cake pressing station of the first baking tray 60 respectively, when the first end is connected with the motor 20, that is, after the end of the swinging rod 411 away from the fan-shaped piece 412 rotates upwards, as shown in fig. 1 and 2, the first baking tray 60 is located at the material waiting station; when the second end is connected to the motor 20, that is, after the end of the swinging rod 411 away from the fan-shaped piece 412 rotates downwards, at this time, the first baking tray 60 is located at the cake pressing station, where the second end and the first end are arranged at intervals and are located at opposite sides of the end face of the fan-shaped piece 412 away from the swinging rod 411 as far as possible, so that the first baking tray 60 can be guaranteed to move to two limit positions, namely, the waiting station and the cake pressing station, which can ensure that dough in the previous procedure enters, and can also ensure that the first baking tray 60 and the second baking tray 61 are tightly abutted, and further a cake with a specified thickness is obtained.

Alternatively, in one embodiment, the fan-shaped piece 412 is connected to the end of the swing rod 411 away from the pushing rod 42, and is integrally formed with the swing rod 411; therefore, the number of parts can be reduced, and the assembly is convenient.

In another embodiment, the fan-shaped piece 412 and/or the swing rod 411 are rotatably connected to the fixed support 10 through a rotation shaft, that is, the swing piece 41 can be rotatably connected to the fixed support 10 through the fan-shaped piece 412, or the swing piece 41 can be rotatably connected to the fixed support 10 through the swing rod 411, so that the fan-shaped piece 412 and the swing rod 411 are in an integrated structure, the number of parts can be reduced, the assembly is convenient, or the swing piece 41 can be used for arranging the fan-shaped piece 412 and the swing rod 411 in a split manner and is rotatably connected to the fixed support 10 through the same rotation shaft, and therefore when the fan-shaped piece 412 and the swing rod 411 are in an integrated structure, the fan-shaped piece 412 and/or the swing rod 411 are subjected to larger acting force, and cracks or even breakage of the swing piece 41 can be avoided, so that the reliability of transmission and the structural stability of each part can be guaranteed.

Referring to fig. 2 to 3, in one embodiment, the sector 412 is provided with a limiting tooth 414 to constrain the swing angle of the swing member 41; the limiting teeth 414 are disposed at the first end side of the fan-shaped member 412, so as to avoid the transmission failure between the fan-shaped member 412 and the motor 20 caused by excessive rotation of the fan-shaped member 412, and also limit the upper limit displacement of the first baking tray 60, where the limiting teeth 414 may be protruding blocks protruding from the fan-shaped member 412.

The limiting teeth 414 are disposed at the second end side of the fan-shaped piece 412, so as to prevent the fan-shaped piece 412 from excessively rotating to cause the first bakeware 60 to excessively press against the second bakeware 61, thereby causing structural failure of the first bakeware 60 and/or the second bakeware 61, and also limiting the lower limit displacement of the first bakeware 60, wherein the limiting teeth 414 can be protruding blocks protruding from the fan-shaped piece 412 or fan-shaped teeth 413 with different sizes arranged on the fan-shaped piece 412. The first bakeware 60 is prevented from excessively pressing against the second bakeware 61, and the compression spring can be arranged in the first bakeware 60 to provide a reaction force to the fan-shaped piece 412 so as to limit the rotation of the fan-shaped piece 412.

Alternatively, in one embodiment, the sector piece 412 has a sector tooth 413 formed thereon, the motor 20 is drivingly connected to the drive gear 30, and the sector tooth 413 and the drive gear 30 are meshed with each other; by the engagement of the sector teeth 413 and the drive gear 30, accurate transmission can be ensured, and further reliability and stability of transmission can be improved. However, in other embodiments, the motor 20 may be drivingly connected with a cam, where the swinging member 41 may only include the swinging rod 411, and the cam is located on an upper side or a lower side of an end of the swinging rod 411 away from the pushing rod 42, and the cam can also be driven by the motor 20 and the cam in a matching manner, so that the swinging rod 411 rotates and drives the pushing rod 42 to drive the first baking tray 60 to move.

Optionally, in an embodiment, the fan-shaped piece 412 and the motor 20 are driven by the reduction gearbox 31, so that the first baking tray 60 can operate more stably and reliably, the up-and-down moving speed of the first baking tray 60 can be controlled, and the stability of the cake pressing module 101 is improved.

Specifically, a link swinging angle β is formed between the moving direction of the first baking tray 60 and the pushing rod 42, and when the first baking tray 60 moves from the waiting station to the cake pressing station, the angle of the link swinging angle β gradually decreases, so that the pushing rod 42 continuously pushes down and drives the first baking tray 60 to move down, and similarly, when the first baking tray 60 moves from the cake pressing station to the waiting station, the angle of the link swinging angle β gradually increases, so that the pushing rod 42 continuously lifts up and drives the first baking tray 60 to move up. The specific angle of the connecting rod swing angle β is related to the distance between the swinging member 41 and the first baking tray 60 and the swinging angle of the swinging member 41, so that the movement interference between the pushing rod 42 and the swinging member 41 needs to be avoided, and the distance between the material waiting station and the cake pressing station of the first baking tray 60 is ensured to obtain the cake with a specified thickness.

Thus, referring to fig. 3 to 4, in one embodiment, the length of the swing link 411 is a, the length of the push rod 42 is b, and the relationship between the length a of the swing link 411 and the length b of the push rod 42 satisfies: 0.3.ltoreq.a/b.ltoreq.0.8, that is, the crank-link ratio is greater than or equal to 0.3, less than or equal to 0.7, specifically, when the crank-link ratio is less than 0.3, the overall size of the cookie module 101 is extremely easily increased, miniaturization of the cookie module 101 cannot be satisfied, and at the same time, the net mass is increased, the cost is increased, and when the crank-link ratio is greater than 0.8, the gain of the force of the first pan 60 at the dead point position is extremely easily smaller than the gain of the force near the dead point position. Therefore, the crank-link ratio is set between 0.3 and 0.8, so that the cookie pressing module 101 can be miniaturized, the net mass is reduced, the cost is reduced, the up-and-down driving of the first bakeware 60 can be reliably satisfied, the smooth operation of the first bakeware 60 can be reliably realized, and the force gain of the first bakeware 60 at the dead point position can be maximized. The specific values of the crank-connecting rod ratio can be 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8. The crank to connecting rod ratio a/b is preferably 0.5.

Optionally, in an embodiment, a is greater than or equal to 25mm and less than or equal to 70mm, specifically, when a is less than 25mm or greater than 70mm, it is very easy to cause the overall size of the cake pressing module 101 to be increased, so that miniaturization of the cake pressing module 101 cannot be satisfied, and at the same time, the net mass is increased, the cost is increased, and the force gain of the first baking tray 60 at the dead point position is also very easy to be smaller than the force gain near the dead point position, so that the reliability of forming cakes from dough is very easy to be reduced. Accordingly, the length a of the swing link 411 is set between 25mm and 70mm, so that the cookie pressing module 101 can be miniaturized, the net mass is reduced, the cost is reduced, and at the same time, the up-and-down driving of the first bakeware 60 and the smooth operation of the first bakeware 60 can be reliably satisfied. The specific value of the length a of the swing rod 411 may be 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, etc. The length a of the swing link 411 is preferably 40mm.

Referring to fig. 4, in an embodiment, the included angle between the moving direction of the first baking tray 60 and the pushing rod 42 is β, β is less than or equal to 50 °, and by defining that the specific value of β is less than or equal to 50 °, labor is saved, and the risk of motion interference between the swinging rod 411 and the pushing rod 42 can be effectively reduced, so that motion failure and structural failure caused by self-locking are avoided, and the reliability of the cake pressing module 101 is improved.

Referring to fig. 2 to 3, in an embodiment, a rotating groove is disposed at an end of the pushing rod 42 away from the first baking tray 60, and the swinging rod 411 is embedded in and rotatably connected to the rotating groove, so as to drive the pushing rod 42 by the swinging rod 411, and further realize the up-and-down movement of the first baking tray 60.

Specifically, the included angle between the swing rod 411 and the central axis of the first baking tray 60 is α, α is greater than or equal to 0 ° and less than or equal to 110 °, and it is understood that the central axis passes through the connection center of the swing rod 411 and the fixed support 10 and the connection center of the pushing rod 42 and the first baking tray 60, and the value range of the included angle α between the swing rod 411 and the central axis of the first baking tray 60 is 0 ° to 110 ° due to the swing rod 411 being embedded in and rotating the rotating groove connected to the pushing rod 42, i.e., the value range of the rotation angle α of the swing rod 411 is 0 ° to 110 °.

When α is 0 °, the swing rod 411 and the pushing rod 42 are located on the same straight line (central axis), the swing angle β of the connecting rod is 0 °, the distance between the waiting station and the cake pressing station is the total length of the swing rod 411 and the pushing rod 42, at this time, the first baking tray 60 is located at the dead point position of the crank slider mechanism 40 (the first baking tray 60 is abutted with the second baking tray 61 to perform cake forming operation of dough), and the self-locking of the crank slider mechanism is adopted to make the pressure maintaining more reliable and less damage to the motor 20; in addition, since the first baking tray 60 is located at the dead point, under the continuous driving of the motor 20, the swinging angle β of the connecting rod is only gradually increased, so as to effectively avoid structural damage or even failure caused by the top dead phenomenon, and improve the reliability of the cake pressing module 101.

Since the crank mechanism 40 has a larger force gain when approaching or reaching the dead point position, the length of the swing link 411 is related to the rotation angle of the swing link 411 and the maximum speed of the first baking tray 60, the driving force for driving the swing link 411 to start rotating can be smaller, in other words, the speed of the first baking tray 60 is 0 when at the dead point position, in other words, compared with the traditional cake pressing module adopting screw rod pressurization, namely, the cake forming operation of the dough is realized by providing uniform and maximum acting force in the process of forming the cake of the dough (such as curve A in fig. 5, the acting force provided by the screw rod in the cake pressing stroke is basically unchanged), in the application, before the first baking tray 60 contacts the dough in the previous procedure, only the resistance of the crank mechanism 40 needs to be overcome by smaller force, when the acting force applied to the dough is gradually increased after the dough contacts, and reaches the maximum acting force when the dough is thinnest (such as curve B in fig. 5, the acting force provided by the crank mechanism 40 is rapidly increased along with the change of the stroke in the cake pressing stroke; curve C, in which the thickness of the dough becomes thinner as the pressure increases during the cookie making process), and at the same time, before the dough is contacted, i.e., the non-working process of the first bakeware 60, the rotation angle α gradually approaches 0 ° from 110 °, the movement speed of the first bakeware 60 gradually decreases, resulting in a faster non-working process speed of the first bakeware 60, and a slower working process speed of the first bakeware 60, which is beneficial to improving the working efficiency and cookie making effect of the cookie making module 101, and further the first bakeware 60 moves a smaller working process, and at this time, the rotation angle of the swing rod 411 is larger, so that the working process of the first bakeware 60 can be precisely controlled by controlling the rotation angle of the swing rod 411 to have higher control accuracy during operation (as shown in the curve in fig. 6, the curve shows the relation between the stroke and the rotation angle alpha, and the stroke is slowly increased when the rotation angle alpha is close to 0 degrees, so that the stroke change can be better shown when the rotation angle alpha has errors, and the accuracy of the stroke detection is improved.

Referring specifically to fig. 5, the force variation characteristics of dough forming are compared with the force application characteristics of the slider-crank mechanism, and the force application characteristics of the conventional screw.

The rotation angle alpha is smaller than 110 degrees, so that the occurrence of the conditions of movement interference between the swing rod 411 and the pushing rod 42, movement interference between the pushing rod 42 and a rotating shaft connected with the swing piece 41 and the like in the operation process of the slider-crank mechanism 40 is effectively avoided, and the movement reliability of the slider-crank mechanism 40 is improved. In addition, the included angle between the pushing rod 42 and the moving direction of the first baking tray 60 is β, and the specific value of β is determined by α and the crank-link ratio a/b.

In another embodiment, the swing rod 411 is rotatably connected to the side portion of the pushing rod 42, and the included angle α between the swing rod 411 and the central axis of the first baking tray 60 can be in the range of 0 ° to 360 °, so that the first baking tray 60 can be driven to move reliably by the crank slider structure 40.

Referring to fig. 2 to 3, in one embodiment, the pressing member 50 is provided at the center of the first baking tray 60, and the pressing member 50 is rotatably connected to the pressing rod 42 to set the pressing member 50, and on one hand, is rotatably connected to the pressing rod 42 to adapt to the driving of the pressing rod 42 and the constraint of the fixing bracket 10; on the other hand, the stress area of the first baking tray 60 is increased, and the pressing piece 50 is arranged at the center of the first baking tray 60, so that the force is conveniently applied to the first baking tray 60, and the whole stress of the first baking tray 60 is ensured to be uniform. In addition, the first bakeware 60 can be prevented from being damaged.

Specifically, in an embodiment, the pressing member 50 includes a base 51 and a limiting portion 52, the base 51 is embedded in the first baking tray 60, the two limiting portions 52 are symmetrically disposed, and are fixedly connected with the base 51 to form a limiting groove, and the pressing rod 42 is rotatably connected with the limiting groove through the connecting sheath 53. The arrangement increases the effective contact areas of the pushing rod 42, the pushing piece 50 and the first baking tray 60, so that transmission is more reliable, meanwhile, the pushing rod 42 is converted from point force application into surface force application to the first baking tray 60 through the connection of the connecting sheath 53, so that the increase of the stress area of the first baking tray 60 is facilitated, and the pushing rod 42 is driven to reliably move between the material waiting station and the cake pressing station. In addition, the two end portions of the connecting pin 53 may be fixedly connected to the two limiting portions 52 through a connecting member, such as a locking pin, wherein the connecting member is stressed to drive the first baking tray 60 to reliably and stably move when the first baking tray 60 is away from the second baking tray 62 (i.e. the crank angle α is increased), and is not effective when the first baking tray 60 approaches the second baking tray 62 to form a cake on dough.

Referring to fig. 1 to 2, in an embodiment, the cake pressing module 101 further includes at least one guide rod 70, wherein the guide rod 70 is disposed along the periphery of the first baking tray 60, one end of the guide rod is connected with the first baking tray 60, and the other end of the guide rod is movably penetrating through the fixing support 10, and it can be understood that the first baking tray 60 is matched with the fixing support 10 by using the guide rod 70 and moves up and down in the fixing support 10 by virtue of the arrangement of the guide rod 70, so as to ensure that the first baking tray 60 can be aligned with and reliably abutted against the second baking tray 61 quickly, thus completing the cake pressing operation, and thus, the cake pressing efficiency of the cake pressing module 101 can be improved.

The guide rods 70 may be provided in plurality, and each guide rod 70 is disposed at intervals and arranged along the periphery of the first bakeware 60, so that the force can be uniformly applied to the periphery of the first bakeware 60 while the guide function is performed. In addition, in order to avoid structural interference of the plurality of guide rods 70 caused by assembly errors and different stresses, each guide rod 70 is not relatively fixed to the first bakeware 60, that is, only connection limitation of the guide rod 70 and the first bakeware 60 in the up-down direction is limited, and under the condition that mutual separation of the guide rod 70 and the first bakeware 60 is avoided, guiding action of the guide rod 70 on the first bakeware 60 is ensured, in other words, the guide rod 70 can be offset in a direction perpendicular to the guide rod 70.

Specifically, in an embodiment, the fixing support 10 is provided with a guide hole corresponding to the guide rod 70, both ends of the guide hole are respectively provided with a guide sleeve 80, one end of the guide rod 70 sequentially passes through the two guide sleeves 80 and is connected with the first baking tray 60, so that the fixing support 10 and the guide rod 70 are effectively prevented from being worn in the moving process, and friction force is further reduced, so that the first baking tray 60 fixed with the guide rod 70 reliably slides.
