Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that in order to better illustrate the contents of the drawings, some of the drawings are turned 90 ° to the left for reading; however, when directions such as "left", "right", "up", "down", etc. are described in the drawings, the directions of the numerals in the drawings are used as the standard; that is, when the reference numerals are set to the left in the drawing, the orientation is based on the case where the drawing is turned 90 ° to the right.

The application discloses adjusting device includes: the adjusting block 10 is provided with an adjusting surface 11 which is obliquely arranged; the adjusting screw rod 20 is in threaded connection with the adjusting block 10; the hand disc 30 is connected with the adjusting screw rod 20; a sliding part 40 which is connected with the piece to be adjusted and can slide along the adjusting surface 11; the hand disk 30 rotates to drive the adjusting screw 20 to rotate, so that the adjusting block 10 moves along the adjusting screw 20, and the sliding member 40 moves along the adjusting surface 11.

As will be readily appreciated, the adjustment block 10 is primarily intended to provide an obliquely disposed adjustment surface 11 so as to guide the slide 40 to "rise" or "fall" with the adjustment surface 11. For example, referring to fig. 3, the adjustment surface 11 is provided to be inclined downward from right to left; the horizontal position of the slide member 40 is controlled to be constant, so that the adjusting block 10 moves in the left-right direction, and the slide member 40 is raised or lowered under the guidance of the adjusting surface 11. For another example, the adjustment surface 11 is inclined from top to bottom and to the right (not shown); at this time, the vertical position of the control slider 40 is not changed, so that the adjusting block 10 moves in the vertical direction, and the slider 40 moves leftward or rightward along the adjusting surface 11.

In other embodiments, the inclined direction of the adjusting surface 11 can be set arbitrarily as required, and the sliding member 40 can be conveniently guided to displace in the required direction in cooperation with the movement of the adjusting block 10. Meanwhile, the position of the sliding part 40 can be adjusted in a small range by guiding the adjusting surface 11, and the sliding part 40 can be conveniently adjusted back and forth to find a proper position, so that the position of the workpiece to be adjusted can be finely adjusted.

It should be added that, in order to prevent the slider 40 from moving along the adjusting screw 20 under the influence of the adjusting block 10, thereby preventing the slider 40 from moving in the preset direction, a guide (e.g., a guide member such as a guide rod, a guide rail, a cam, etc.) for guiding the movement of the slider 40 may be provided. For example, in the embodiment shown in fig. 3, in order to "control the horizontal position of the slider 40 to be constant", a guide extending in the vertical direction may be provided, and the slider 40 may be slidably disposed on the guide, so that the slider 40 can only move in the vertical direction, and cannot be moved in the left-right direction by the adjusting block 10.

The sliding member 40 may be a roller, a follower, or other rotatable sliding member, so that when the sliding member 40 moves along the adjustment surface 11, the sliding member 40 can rotate to relieve the friction force therebetween, so that the sliding member 40 can slide along the adjustment surface 11.

Of course, the sliding member 40 may be any member that can contact the adjustment surface 11, and may even be a part of the member to be adjusted, regardless of the frictional resistance, as long as it can contact the adjustment surface 11 and can change the position for guiding the adjustment surface 11. Further, the surface of the sliding member 40 contacting the adjusting surface 11 may be provided as an arc surface or a plane parallel to the adjusting surface 11, so as to avoid the sliding member 40 having a contact position of both edges and scratches.

In one embodiment, referring to fig. 1 and 2, the adjusting device is used to adjust the inclination of the rolls 1' in the coater. At this time, the member to be regulated is the press roll 1'. Specifically, swing arms 2 'are disposed at two ends of the press roll 1', and the swing arms 2 'are rotatably disposed on a frame (not shown) through a rotating shaft 3'. One end of the swing arm 2 'is connected with the press roller 1', and the other end is connected with the sliding part 40. The sliding part 40 is arranged on the adjusting surface 11 in a sliding manner; at this time, in the non-adjustment state, the adjustment block 10 is used to provide a supporting force to lift the slider 40 so that the position of the platen roller 1' is stabilized. When in adjustment, an operator rotates the adjusting screw 20 through the hand disc 30, so that the adjusting block 10 is close to or far away from the press roll 1'; because the adjusting surface 11 inclines downwards towards the press roll 1 ', the sliding part 40 can ascend along with the approach of the adjusting block 10 to the press roll 1 ', the swing arm 2 ' rotates around the rotating shaft 3 ', and the press roll 1 ' descends along with the rotation; as the adjusting block 10 moves away from the platen roller 1 ', the slider 40 descends, the swing arm 2' rotates around the rotation shaft 3 ', and the platen roller 1' ascends. Thereby, a fine adjustment of the inclination of the press roll 1' is achieved by means of the adjusting device.

In addition, the adjusting block 10 is also used for being in threaded connection with the adjusting screw 20. It is easy to understand that, in order to ensure the thread precision and thus the movement precision of the adjusting block 10, at least the threaded connection part of the adjusting block 10 and the adjusting screw 20 is made of metal material.

Wherein, a through first channel 12 is arranged in the adjusting block 10, and the first channel 12 is provided with internal threads; the adjusting screw 20 comprises a threaded section 21, and the threaded section 21 is provided with continuous and spiral external threads on the rod; when the adjusting screw 20 is inserted into the first channel 12, the external thread of the thread section 21 is screwed with the internal thread in the first channel 12, so that the threaded connection between the adjusting screw 20 and the adjusting block 10 is realized.

It is easily conceivable that the threaded section 21 is rotated, and the adjustment block 10 can be moved along the threaded section 21 by means of the internal and external thread cooperation. In the process of thread action, metal internal threads and metal external threads rub against each other to generate metal dust; such dust can interfere with the operation of the equipment and can also affect the quality of the preparation made in the equipment. For example, when the equipment is used for processing battery pole pieces, metal dust falls on the battery pole pieces, and the quality of the pole pieces is affected.

In order to ensure that the generated dust is not easy to affect equipment or prepared products when the metal external thread and the metal internal thread interact, the regulating block 10 provided by the application has the protruding thread part 13 in the first channel 12, the internal thread is arranged on the thread part 13, and the thread part 13 is screwed with the thread part 21; in addition, the inner diameter of the end of the first passage 12 is larger than the rod diameter of the adjusting screw thread section 21.

In brief, the threaded portion 13 is a portion having internal threads in the first channel 12, when the adjusting screw 20 is inserted into the first channel 12, the threaded portion 13 is screwed with the threaded section 21, and other portions in the first channel 12 do not contact the threaded section 21. As will be appreciated, when the adjustment screw 20 is rotated, its threaded section 21 acts on the threaded section 13, thereby moving the adjustment block 10 along the rod via the threaded section 13. The other parts in the first channel 12 have a clearance with the threaded section 21 to form a reserved space because the other parts do not contact the threaded section 21; metal dust generated by friction between the threaded part 13 and the threaded part 21 can be contained in the empty space, and further the dust is prevented from affecting equipment or prepared products.

It should be added that, as the first channel 12 penetrates through the adjusting block 10, both ends of the first channel 12 are respectively provided with an inlet and an outlet. At this time, at least both ends of the first passage 12 do not contact the screw thread segments 21, forming a vacant space. Referring to fig. 4 and 5, in one embodiment, the first passage 12 is divided into three sections, namely, a first end portion 14, a threaded portion 13 and a second end portion 15 from left to right; the internal diameter of the threaded portion 13 is smaller than the internal diameter of the first end portion 14 and the second end portion 15 within the first channel 12 due to the threaded portion 13 protruding inwardly of the channel; the thread part 13 is provided with internal threads which can be screwed with the thread part 21; the first end part 14 and the second end part 15 form a space for accommodating dust; in this way, the screw thread portion 13 and the screw thread portion 21 are screwed, and the generated metal dust can be accommodated in the space of the first end portion 14 or the second end portion 15, thereby preventing the dust from flying out.

In other embodiments, the first channel 12 may have a plurality of spaced thread portions 13, the thread portions 13 are all used for being in threaded connection with the thread portion 21, and a gap between two adjacent thread portions 13, whose inner diameter is greater than the rod diameter of the thread portion 21, can form a space to accommodate dust generated by friction of metal parts.

It is necessary to supplement that at least two ends of the first channel 12 have a larger inner diameter, forming a void space; when the screw portion 13 is provided at the end of the first passage 12, dust generated by friction thereof is prevented from directly overflowing the first passage 12.

Further, the entrance and exit of the first channel 12 are provided with dust rings 1, which can cover the first channel 12 and prevent dust from entering or leaving the first channel 12.

It will be readily appreciated that without the first passageway 12 being capped, the dust may still be susceptible to impact on the equipment or the article being manufactured as it flies or as the conditioning block 10 moves along the conditioning screw 20, exposing the dust. For this purpose, the dust ring 1 is provided to seal both ends of the first passage 12 and separate the inside of the first passage 12 from the outside, thereby preventing the dust from overflowing.

Furthermore, the dust ring 1 is made of non-metal materials; the dust ring 1 is sleeved on the adjusting screw rod 20. For example, the dust ring 1 can be made of plastic or rubber; so, dust ring 1 contact adjusting screw 20, and the two rubs, also can not produce the metal dust to avoid the influence of dust. Meanwhile, the dust ring 1 made of the non-metal material has certain elasticity, and when the dust ring is sleeved on the adjusting screw rod 20, the dust ring 1 has certain pressure on the contact position; in this way, the dust ring 1 can better seal the first passage 12 and prevent dust from overflowing from the gap.

In addition, if the dust ring 1 is directly covered on the outer side of the inlet and outlet of the first channel 12, when the dust ring 1 is made of a non-metal material, it is difficult to directly fix the dust ring on the adjusting block 10.

To this end, in one embodiment, referring to fig. 4 and 5, the first channel 12 end also has a dust mount 16; the dust-proof mounting portion 16 is located on a side of the first end portion 14 or the second end portion 15 away from the threaded portion 13. The inner diameter of the dust-proof mounting portion 16 is larger than the inner diameters of the first end portion 14 and the second end portion 15. The dustproof ring 1 is arranged in the dustproof mounting part 16, and one surface of the dustproof mounting part, which is deviated from the inlet and the outlet, can be abutted against the pipe orifice of the first end part 14 or the second end part 15; in this way, on the one hand, the first end 14 and the second end 15 can be better sealed; on the other hand, the position of the dust ring 1 can be limited, and the dust ring 1 is prevented from moving.

Furthermore, a retainer ring 50 is arranged on one surface of the dust ring 1, which is far away from the first channel 12, and the retainer ring 50 is fixedly arranged on the adjusting block 10 and used for limiting the position of the dust ring 1; the retainer ring 50 is provided with a through second channel 51; the inner diameter of the second passage 51 is larger than the rod diameter of the adjusting screw rod 20; the second passage 51 communicates with the first passage 12.

The retainer ring 50 is made of a metal material, and the outer wall thereof can be reliably and fixedly connected with the adjusting block 10 by forming threaded holes and locking screws.

In one embodiment, if the dust ring 1 is disposed outside the inlet/outlet of the first channel 12 (not shown), the retainer ring 50 may be disposed in an "Ω" shape; at this time, the retainer ring 50 includes a "hat" portion that protrudes to cover the dust seal 1, and a "visor" portion that contacts the outer wall of the adjustment block 10.

In another embodiment, referring to fig. 4, if the dust seal 1 is disposed in the dust-proof mounting portion 16, the retainer ring 50 may be disposed in a plate shape and directly cover the outside of the inlet/outlet of the first passage 12. Thus, when the thickness of the dust ring 1 exactly matches the depth of the dust-proof mounting portion 16, the surface of the dust ring 1 away from the inlet and outlet of the first channel 12 can abut against the pipe orifice of the first end portion 14 or the second end portion 15, and the surface close to the inlet and outlet of the first channel 12 can abut against the retainer ring 50, so as to better limit the position of the retainer ring 50.

The second passage 51 having a large inner diameter avoids the adjusting screw 20, and prevents the metal retainer ring 50 and the metal adjusting screw 20 from rubbing against each other and generating metal dust. The second passage 51 communicates with the first passage 12 so that the adjusting screw 20 penetrates the second passage 51 and the first passage 12 to be screwed with the screw portion 13.

It should be noted that the first passage 12 has two ends penetrating through the adjusting block 10, and for this purpose, two sets of the dust seal 1 and the retainer ring 50 are provided, respectively, at one end of the first passage 12.

In order to limit the movement direction of the adjusting block 10 and avoid that the adjusting screw 20 rotates spirally, the adjusting block 10 rotates around the adjusting screw 20 to influence the adjusting block 10 to do linear movement along the adjusting screw 20, the adjusting device further comprises a block guide 60, and the adjusting block 10 is arranged on the block guide 60 in a sliding manner; the block guide 60 extends in the same direction as the adjustment screw 20 and can define the moving direction of the adjustment block 10.

The block guide 60 may be a guide structure such as a guide rod or a guide rail. Alternatively, the block guide 60 includes a guide block 61; one side surface of the guide block 61 is recessed to form a guide groove 62 which can be clamped with the adjusting block 10; the guide groove 62 extends in the same direction as the adjustment screw 20 and can define the movement direction of the adjustment block 10.

In one embodiment, referring to fig. 3 to 5, the adjusting screw 20 extends in the left-right direction, the guide groove 62 is opened on the upper surface of the guide block 61 and also extends in the left-right direction, and the lower part of the adjusting block 10 is caught in the guide groove 62. Thus, the adjusting screw 20 is rotated, and the adjusting block 10 is caught by the guide groove 62 and can move only in the left and right directions along the guide groove 62.

Because the guide slot 62 has the guide effect, in order to avoid the guide slot 62 to warp, the guide block 61 adopts metal material to make, and the direction precision is high. In order to avoid the friction between the adjusting block 10 and the guide groove 62 and the generation of metal dust, the bottom of the adjusting block 10 is provided with a spacer 2, and the spacer 2 is clamped in the guide groove 62; when the adjusting block 10 moves along the adjusting screw 20, the spacer 2 moves along the guide groove 62.

Wherein, the isolating piece 2 is made of non-metallic materials; for example, the spacer may be made of POM (polyoxymethylene), which has high hardness and is not easily deformed, and when the guide block 61 is stably driven to move along the guide groove 62, the spacer 2 and the guide groove 62 contact and rub against each other, so that metal dust is not generated.

To facilitate the mounting of the adjusting screw 20, the adjusting device further comprises a fixing member 70. The fixing member 70 may be a fixing block (which fixes the adjusting screw 20 to the fixing block by a screw hole screw), a fixing jig, or the like.

Alternatively, the fixing member 70 may include: the locking block 71 is provided with a third through channel 72 for the adjusting screw rod 20 to penetrate through; one side of the locking block 71 is open and is communicated with a third channel 72; and a locking screw 73 capable of locking the opening and thereby controlling the clamping of the third channel 72 or loosening of the adjusting screw 20. At this time, the locking block 71 is similar to the hoop, and when the locking screw 73 is not screwed into the opening, the third channel 72 can be opened, so as to facilitate the movement of the adjusting screw 20; the adjusting screw 20 is in place, the locking screw 73 is screwed down, the opening is compressed, the third channel 72 is closed, and then the adjusting screw 20 is pressed, and the adjusting screw 20 is positioned.

Since the adjusting screw 20 needs to be rotated, it is not avoided that the adjusting screw 20 is clamped by the third channel 72, which affects the rotation; in one embodiment, the locking block 71 is made of a non-metal material (e.g., plastic or rubber); it can be seen that by controlling the tolerance dimension of the locking block 71, the adjusting screw 20 can normally rotate within the third channel 72; in addition, the locking piece 71 made of a non-metallic material and the adjusting screw 20 made of a metal rub against each other, and metal dust is not generated.

Further, in order to better define the relative positions of the adjustment screw 20 and the third channel 72, and to avoid axial movement of the adjustment screw 20 along the third channel 72, a protruding gripping portion 74 is provided in the third channel 72; meanwhile, the adjusting screw 20 further comprises a clamping section 22 and limiting sections 23 positioned at two ends of the clamping section 22, and the rod diameter of the limiting sections 23 is larger than that of the clamping section 22; when the adjusting screw 20 is inserted into the third channel 72, the clamping portion 74 extends into the clamping section 22.

Since the clamping section 22 and the limiting section 23 are not used for being in threaded connection with the adjusting block 10, the clamping section 22 and the limiting section 23 may not be provided with external threads.

Referring to fig. 4 and 6, the horizontal projection of the adjusting screw 20 formed by the clamping section 22 and the limiting section 23 is substantially in an i shape; referring to fig. 5, the third channel 72 has a longitudinal section that is substantially in the form of two opposing "male" shapes; after the opening is locked, the clamping part 74 extends into the clamping section 22 sunken in relative limiting section 23, and the limiting sections 23 on two sides can prevent the clamping part 74 from leaving the clamping section 22.

Further, after the clamping part 74 extends into the clamping section 22, one surface of the limiting section 23 close to the clamping section 22 can be attached to the side wall surface of the clamping part 74; in this way, the two stop segments 23 can "grip" the gripping portion 74 from both sides, thereby more accurately defining the position of the adjustment screw 20.

In other embodiments, a plurality of spaced gripping portions 74 may be disposed in the third channel 72, and correspondingly, a plurality of spaced gripping sections 22 may be disposed on the adjustment screw 20; meanwhile, the two ends of the clamping sections 22 are provided with limiting sections 23 with larger rod diameters so as to limit the positions of the clamping parts 74 when the clamping parts 74 extend into the clamping sections 22.

Or in other embodiments, the inner walls forming the third channel 72 are the clamping portions 74, and after the clamping portions 74 extend into the clamping section 22, the limiting sections 23 at the two ends of the clamping section 22 can clamp the outer walls of the inlet and the outlet of the third channel 72.

By providing the fixing member 70, it is also possible to define the relative positions of the adjusting screw 20 and the block guide 60; at this time, the fixing member 70 is disposed at one side of the block guide 60, and the orientation of the third passage 72 is the same as the guiding direction of the block guide 60; the fixing member 70 can prevent the adjusting screw 20 from being displaced relative to the block guide 60 during the debugging process, affecting the debugging effect,

in order to define the extension direction of the adjusting screw 20 and avoid the orientation of the adjusting screw 20 from changing during rotation, the adjusting device further comprises a screw guide 80; the screw guide 80 includes: and the guide seat 81 is provided with a through fourth channel on the guide seat 81 for the adjusting screw 20 to penetrate through. For example, referring to fig. 3 to 5, the fourth channel extends in the left-right direction; in this way, when the adjusting screw 20 is inserted into the fourth channel, the fourth channel will limit the adjusting screw 20 to be arranged along the left-right direction.

In addition, since the portion of the adjusting screw 20 inserted into the fourth passage does not need to be screwed with the adjusting block 10, the adjusting screw 20 may not be provided with external threads.

Further, in order to ensure the guiding precision, a guiding bush 82 is arranged in the fourth channel, and the adjusting screw 20 passes through the guiding bush 82 and the fourth channel and is in threaded connection with the adjusting block 10. It can be seen that the guide seat 81 is mainly used for convenient installation; for example, referring to fig. 3 to 5, a guide holder 81 is provided at one side of the fixing member 70 and is coupled to the block guide 60; in this way, on the one hand, it is convenient to associate the adjusting screw 20 with the adjusting block 10, and on the other hand, the guide seat 81, adjacent to the fixing element 70, is able to define its orientation in a more stable position of the adjusting screw 20, and thus better guide the adjusting screw 20. Therefore, the accuracy of the fourth passage provided in the guide holder 81 is not easily ensured, and the guide bush 82 having high accuracy is provided, so that the guide accuracy can be improved, and the inner wall surface of the guide bush 82 is smooth, thereby preventing the surface of the rod of the adjusting screw 20 from being worn when the adjusting screw 20 rotates.

Further, the guide bushing 82 is made of a non-metal material (such as plastic or rubber); when the adjusting screw 20 is inserted into the guide bush 82, the guide bush 82 contacts the adjusting screw 20. In this way, the adjusting screw 20 rotates, and the rod surface thereof and the guide bush 82 rub against each other, so that metal dust is not generated. In addition, the guide bush 82 made of plastic has high hardness, and the adjustment screw 20 can be ensured to normally rotate in the guide bush 82 by controlling the tolerance dimension.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
