The drum-type moisture-reconditioning machine mainly includes a drum, a clamping ring, a roller and other components, wherein the clamping ring is arranged on the outer circumference of the drum, and the roller is arranged near the end of the drum and the roller and the clamping ring are in friction contact to drive the drum to rotate. The material is placed in the drum, and when the drum rotates, the material moves in the drum. At this time, water or liquid is added to the material in the drum to rehumidify the material.

[0003] In actual production, after the daily production of the conditioning machine is completed, the operator has to enter the drum to clean the drum wall. Due to the lack of a dedicated drum limiter, the drum may rotate unexpectedly when the operator is cleaning the drum wall, affecting the operator's personal safety. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the operator enters the drum to clean the drum, the drum is prone to rotate, resulting in reduced operational safety. The utility model provides a limit device that can limit the rotation of the drum, thereby preventing the drum from accidentally rotating when the operator enters the drum, thereby improving operational safety.

[0005] In order to solve the above technical problems, the embodiment of the utility model discloses a limiting device, which is used to limit the rotation of the drum on the rehumidifier around its own axis. The rehumidifier is also provided with a clamping ring and at least two rollers. The clamping ring is arranged on the outer circumference of the drum. The circumference of each roller is in contact with the clamping ring. The roller can rotate around its own axis to drive the drum to rotate around its own axis. The limiting device includes:

[0006] The clamping mechanism comprises an operating part and two clamping parts arranged opposite to each other, wherein the operating part is connected with the two clamping parts to control the clamping or loosening of the two clamping parts;

[0007] The two limiting parts are respectively connected to the two clamping parts. When the clamping parts are clamped, the two limiting parts are respectively used to clamp into the two sides of the contact point between the roller and the drum to limit the rotation of the drum around its own axis.

The two limiting parts are respectively clamped into the two sides of the contact point between the roller and the clamping ring, and the two limiting parts are in frictional contact with the circumferential surfaces of the roller and the clamping ring at the same time, so that the relative rotation of the roller and the roller can be restricted. The above technical solution can prevent the roller from rotating accidentally when the operator enters the drum for cleaning, thereby improving the safety of the operation.

[0009] Optionally, the limiting portion is a limiting rod, and when the two limiting rods are respectively clamped into the two sides of the contact point between the roller and the clamping ring, the extension direction of the limiting rod is parallel to the axis of the roller.

[0010] Optionally, the limiting device also includes two abutment rods, which are arranged between the clamping portion and the limiting rod. The abutment rods are perpendicular to the extension direction of the limiting rod. When the two limiting rods are respectively inserted into both sides of the contact point, the two abutment rods abut against the end face of the roller.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the embodiment of the utility model discloses a limiting device for limiting the rotation of the drum 9 on the rehumidifier 8 around its own axis. Specifically, the axis of the drum 9 is Figure 1The X direction in is parallel. The rehumidifier 8 is also provided with a clamping ring 10 and four rollers 11, wherein the clamping ring 10 is arranged on the outer circumferential surface of the drum 9, and the four rollers 11 are rotatably arranged on the frame. The rollers 11 are located below the drum 9, and the circumferential surface of each roller 11 is in contact with the clamping ring 10. The four rollers 11 rotate in the same direction around their own axes, thereby driving the drum 9 to rotate around its own axis. The limiting device includes a clamping mechanism 12 and two limiting parts 3. Among them, the clamping mechanism 12 includes an operating part 1 and two clamping parts 2 arranged oppositely, and the operating part 1 is connected to the two clamping parts 2 to control the clamping or loosening of the two clamping parts 2. Exemplarily, the clamping mechanism 12 can be a locking pliers, which includes two clamp arms and two handles. Among them, a locking member 5 is provided on the handle, the two clamp arms constitute the two clamping parts 2, and the two handles constitute the operating part 1. When the two handles are pressed, the two clamp arms approach and clamp the object, and the locking member 5 automatically locks the two clamp arms; when the object needs to be released, the two handles only need to be separated, the locking member 5 automatically unlocks, and the two clamp arms separate. The two limiting parts 3 are respectively connected to the two clamping parts 2. When the clamping parts 2 are clamped, the two limiting parts 3 are respectively used to clamp the two sides of the contact point between the roller 11 and the drum 9 to limit the drum 9 from rotating around its own axis.

[0027] When using, Figure 4 As shown, a stopper 3 is inserted at the positions on both sides of the contact point between the roller 11 and the snap ring 10, and then the two handles are pressed to clamp the two clamping parts 2. At this time, the two stoppers 3 are respectively clamped into the two sides of the contact point between the roller 11 and the snap ring 10, and the two stoppers 3 are in friction contact with the circumferential surfaces of the snap ring 10 and the roller 11 at the same time, so that the relative rotation of the drum 9 and the roller 11 can be restricted. The above technical solution can prevent the drum 9 from rotating accidentally when the operator enters the drum 9 for cleaning, thereby improving the safety of the operation.

[0028] Alternatively, if Figure 2 and Figure 3 As shown, the limiting part 3 is a limiting rod. When the two limiting rods are respectively inserted into the two sides of the contact point between the roller 11 and the roller 9, the extension direction of the limiting rod (such as Figure 2 The Y direction is parallel to the axis of the roller 9, thereby increasing the contact area between the limit rod and the circumferential surface of the clamping ring 10 and limiting the rotation of the roller 9 to the greatest extent.

[0029] Alternatively, if Figures 2 to 4 As shown, the limiting device also includes two abutment rods 4, which are arranged between the clamping part 2 and the limiting rod, one end of the abutment rod 4 is connected to the clamping part 2, and the other end of the abutment rod 4 is connected to the limiting rod, and the abutment rod 4 is perpendicular to the extension direction of the limiting rod. When the two limiting rods are respectively inserted into the two sides of the contact point, the two abutment rods 4 are both in abutment with the end face of the roller 11.

[0030] The above technical solution can, on the one hand, prevent the limiting rod from being inserted too deeply, causing the operating part 1 to be pressed between the retaining ring 10 and the roller 11 and affecting the normal use of the operating part 1; on the other hand, when the abutment rod 4 is pressed against the end face of the roller 11, the positioning stability of the limiting rod can be increased to prevent the limiting rod from slipping between the retaining ring 10 and the roller 11 and moving.

[0031] Optionally, an anti-skid sleeve is provided on the limit rod, which can increase the friction between the limit rod and the clamping ring 10 and the roller 11, thereby preventing the limit rod from slipping. Specifically, the anti-skid sleeve is made of plastic material.

[0032] The utility model provides a limiting device which can limit the rotation of the drum 9, thereby preventing the drum 9 from accidentally rotating when the operator enters the drum 9 for cleaning, thereby improving the safety of the operation.

[0033] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
