Description

Technical Field

[0001] This application relates to the field of cigarette processing equipment technology, and in particular to a float adjustment mechanism. Background Technology

[0002] The closing or slitting drum of a cigarette rolling machine typically has two floats, with the two ends of the cigarette resting against the inner sides of the two floats. To accommodate cigarettes of different lengths, a float adjustment mechanism is usually used to adjust the float angle.

[0003] The float ring adjustment mechanism includes a sleeve and two adjusting seats movably fitted onto the sleeve. The two adjusting seats are used to abut against the two float rings. The distance between the two adjusting seats is adjusted along the axial direction of the sleeve by two screws, thereby adjusting the angle between the float rings. However, when the float ring adjustment mechanism is subjected to external force and vibrates, the screws are prone to loosening and rotating, causing the adjusting seats to move along the axial direction of the sleeve on their own. Utility Model Content

[0004] Therefore, it is necessary to provide a float ring adjustment mechanism that can prevent the screw from rotating unexpectedly, causing the adjustment seat to move along the axial direction of the sleeve.

[0005] A float ring adjustment mechanism is provided for adjusting the distance between two float rings on a drum. The float ring adjustment mechanism includes a sleeve, a first adjusting seat, a second adjusting seat, a fixed seat, a first adjusting screw, a second adjusting screw, and a locking element. The first adjusting seat and the second adjusting seat are movably sleeved on the outer periphery of the sleeve. The fixed seat is fixedly connected to one end of the sleeve. One end of the first adjusting screw is connected to the fixed seat through the locking element, and the other end is threaded to the first adjusting seat. One end of the second adjusting screw is connected to the fixed seat through the locking element, and the other end is threaded to the second adjusting seat. The locking element has a locked state and an unlocked state. When the locking element is in the unlocked state, both the first adjusting screw and the second adjusting screw can rotate in response to external force. When the locking element is in the locked state, both the first adjusting screw and the second adjusting screw are locked to the fixed seat and cannot rotate.

[0006] In one embodiment, at least a portion of the first adjusting screw extends out of the end face of the fixed seat and forms a first mounting portion, and at least a portion of the second adjusting screw extends out of the end face of the fixed seat and forms a second mounting portion; a locking member is fixedly mounted on the fixed seat, the locking member has an assembly gap, the first mounting portion and the second mounting portion are both located in the assembly gap, and the assembly gap is configured to be adjustable along the radial width of the sleeve so that the locking member can clamp the first mounting portion and the second mounting portion, or loosen the first mounting portion and the second mounting portion.

[0007] In one embodiment, the locking member includes a first clamping block, a second clamping block, and a fixing member. The first clamping block is fixedly connected to the fixing base, and the second clamping block is adjustablely connected to the second clamping block along the radial direction of the sleeve through the fixing member, and an assembly gap is formed between the second clamping block and the first clamping block.

[0008] In one embodiment, the first clamping block and / or the second clamping block have a first groove corresponding to the first mounting portion, the first groove being used to fit against at least a portion of the surface of the first mounting portion; the first clamping block and / or the second clamping block have a second groove corresponding to the second mounting portion, the second groove being used to fit against at least a portion of the surface of the second mounting portion.

[0009] In one embodiment, the fastener is configured as a fastening screw, the first clamping block has a first threaded hole, the second clamping block has a second threaded hole, the first threaded hole and the second threaded hole are correspondingly arranged and extend radially along the sleeve respectively, and the fastening screw is threadedly connected to the first threaded hole and the second threaded hole.

[0010] In one embodiment, the first mounting portion and the second mounting portion are arranged radially spaced along the sleeve, and the fastener is located radially between the first mounting portion and the second mounting portion along the sleeve.

[0011] In one embodiment, a first protrusion is provided on the outer periphery of the sleeve, and a first groove is provided on the inner peripheral wall of the first adjusting seat. The first groove can slide and engage with the first protrusion along the axial direction of the sleeve. A second protrusion is provided on the outer periphery of the sleeve, and a second groove is provided on the inner peripheral wall of the second adjusting seat. The first groove can slide and engage with the second protrusion along the axial direction of the sleeve.

[0012] In one embodiment, the number of first protrusions is configured to be multiple, and the multiple first protrusions are distributed at intervals along the circumference of the sleeve; the number of second protrusions is configured to be multiple, and the multiple second protrusions are distributed at intervals along the circumference of the sleeve.

[0013] In one embodiment, the sleeve has a mounting base at one end along its own axial direction away from the fixed base, the mounting base being used for detachable connection to an external support structure.

[0014] In one embodiment, the float adjustment mechanism further includes a first rod and a second rod. One end of the first rod is detachably connected to the outer peripheral wall of the first adjustment seat, and the other end is provided with a first roller. The first roller is used to abut against the outer side of one of the floats. One end of the second rod is detachably connected to the outer peripheral wall of the second adjustment seat, and the other end is provided with a second roller. The second roller is used to abut against the outer side of the other float.

[0015] Compared with the prior art, the float adjustment mechanism provided in this application allows the user to move the first adjustment seat left and right along the axial direction of the sleeve by turning the first adjustment screw when the locking member is in the unlocked state. When the locking member is in the locked state, the first adjustment screw is locked to the fixed seat, thereby preventing the first adjustment screw from rotating when the float adjustment mechanism vibrates due to external force, and thus preventing the first adjustment seat from moving along the axial direction of the sleeve on its own. Similarly, when the locking member is in the unlocked state, the user can move the second adjustment seat left and right along the axial direction of the sleeve by turning the second adjustment screw. When the locking member is in the locked state, the second adjustment screw is locked to the fixed seat, thereby preventing the second adjustment screw from rotating when the float adjustment mechanism vibrates due to external force, and thus preventing the second adjustment seat from moving along the axial direction of the sleeve on its own.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figure 1This application provides a float ring adjustment mechanism 100, which is used to adjust the distance between two float rings 210 on a drum 200. The float ring adjustment mechanism 100 includes a sleeve 110, a first adjusting seat 120, a second adjusting seat 130, a fixed seat 140, a first adjusting screw 150, a second adjusting screw 160, and a locking member 170. The first adjusting seat 120 and the second adjusting seat 130 are respectively movably sleeved on the outer periphery of the sleeve 110. The fixed seat 140 is fixedly connected to one end of the sleeve 110. One end of the first adjusting screw 150 is connected to the locking member 170. One end of the first adjusting screw 150 is connected to the fixed base 140, and the other end is threaded to the first adjusting base 120. One end of the second adjusting screw 160 is connected to the fixed base 140 through the locking member 170, and the other end is threaded to the second adjusting base 130. The locking member 170 has a locked state and an unlocked state. When the locking member 170 is in the unlocked state, both the first adjusting screw 150 and the second adjusting screw 160 can rotate in response to external force. When the locking member 170 is in the locked state, both the first adjusting screw 150 and the second adjusting screw 160 are locked to the fixed base 140 and cannot rotate.

[0026] Understandably, with this configuration, when the locking element 170 is in the unlocked state, the user can move the first adjusting seat 120 left and right along the axial direction of the sleeve 110 by turning the first adjusting screw 150. When the locking element 170 is in the locked state, the first adjusting screw 150 is locked to the fixed seat 140, thereby preventing the first adjusting screw 150 from rotating when the float adjusting mechanism 100 vibrates due to external force, and thus preventing the first adjusting seat 120 from moving independently along the axial direction of the sleeve 110. Similarly, when the locking element 170 is in the unlocked state, the user can move the second adjusting seat 130 left and right along the axial direction of the sleeve 110 by turning the second adjusting screw 160. When the locking element 170 is in the locked state, the second adjusting screw 160 is locked to the fixed seat 140, thereby preventing the second adjusting screw 160 from rotating when the float adjusting mechanism 100 vibrates due to external force, and thus preventing the second adjusting seat 130 from moving independently along the axial direction of the sleeve 110.

[0027] In one embodiment, such as Figure 1 and Figure 2As shown, at least a portion of the first adjusting screw 150 extends out of the end face of the fixed base 140 and forms a first mounting portion 151, and at least a portion of the second adjusting screw 160 extends out of the end face of the fixed base 140 and forms a second mounting portion 161. A locking member 170 is fixedly mounted on the fixed base 140. The locking member 170 has an assembly gap 171, where both the first mounting portion 151 and the second mounting portion 161 are located. The assembly gap 171 is adjustable in width along the radial direction of the sleeve 110, allowing the locking member 170 to clamp or release the first mounting portion 151 and the second mounting portion 161. Thus, by reducing the width of the assembly gap 171 radially along the sleeve 110, the locking member 170 is locked, simultaneously clamping the first mounting portion 151 and the second mounting portion 161 to prevent the first adjusting screw 150 and the second adjusting screw 160 from rotating. Furthermore, by increasing the width of the assembly gap 171 radially along the sleeve 110, the locking member 170 is switched to the unlocked state, and the locking member 170 simultaneously releases the first mounting part 151 and the second mounting part 161, making operation convenient.

[0028] Optionally, in one embodiment, the first adjusting screw 150 has a first boss (not shown) sandwiched between the locking member 170 and the fixing seat 140 to prevent the first adjusting screw 150 from moving axially along the sleeve 110. The second adjusting screw 160 has a second boss (not shown) sandwiched between the locking member 170 and the fixing seat 140 to prevent the second adjusting screw 160 from moving axially along the sleeve 110.

[0029] Specifically, in one embodiment, the locking member 170 includes a first clamping block 172, a second clamping block 173, and a fixing member 174. The first clamping block 172 is fixedly connected to the fixing base 140. The second clamping block 173 is adjustablely connected to the second clamping block 173 along the radial direction of the sleeve 110 through the fixing member 174, and an assembly gap 171 is formed between the second clamping block 172 and the first clamping block 172.

[0030] Optionally, in one embodiment, the fastener 174 is configured as a fastening screw. The first clamping block 172 has a first threaded hole (not shown), and the second clamping block 173 (not shown) has a second threaded hole. The first threaded hole and the second threaded hole are correspondingly arranged and extend radially along the sleeve 110, respectively. The fastening screw is threadedly connected to the first threaded hole and the second threaded hole. In this way, the distance between the first clamping block 172 and the second clamping block 173 can be adjusted by tightening the fastening screw, that is, the width of the assembly gap 171 can be adjusted radially along the sleeve 110. Specifically, one end of the fastening screw passes through the second threaded hole into the second clamping block 173 and extends into the first threaded hole.

[0031] Optionally, in one embodiment, the first mounting portion 151 and the second mounting portion 161 are arranged radially spaced along the sleeve 110, and the fixing member 174 is located radially between the first mounting portion 151 and the second mounting portion 161 along the sleeve 110. In this way, while facilitating the adjustment of the assembly gap 171 width, the first mounting portion 151 and the second mounting portion 161 are subjected to more even force when the locking member 170 is in the locked state.

[0032] Furthermore, the first mounting part 151 and the second mounting part 161 are symmetrically distributed on both sides of the fastener 174.

[0033] Optionally, in one embodiment, the first clamping block 172 has a first groove 1721 corresponding to the first mounting portion 151. Alternatively, in another embodiment, the second clamping block 173 has a first groove 1721 corresponding to the first mounting portion 151. Or, in yet another embodiment, both the first clamping block 172 and the second clamping block 173 may have first grooves 1721 corresponding to the first mounting portion 151. The first groove 1721 is used to fit against at least a portion of the surface of the first mounting portion 151. This increases the contact area between the first clamping block 172 or the second clamping block 173 and the first mounting portion 151, thereby allowing the first clamping block 172 and the second clamping block 173 to clamp the first mounting portion 151 more securely.

[0034] Optionally, in one embodiment, the first clamping block 172 has a second groove 1731 corresponding to the second mounting portion 161. Alternatively, in another embodiment, the second clamping block 173 has a second groove 1731 corresponding to the second mounting portion 161. Or, in yet another embodiment, both the first clamping block 172 and the second clamping block 173 have second grooves 1731 corresponding to the second mounting portion 161. The second groove 1731 is used to fit against at least a portion of the surface of the second mounting portion 161. This increases the contact area between the first clamping block 172 or the second clamping block 173 and the second mounting portion 161, thereby allowing the first clamping block 172 and the second clamping block 173 to clamp the second mounting portion 161 more securely.

[0035] Specifically, both the first groove 1721 and the second groove 1731 are configured as semi-circular grooves.

[0036] In one embodiment, the sleeve 110 has a first protrusion 111 on its outer periphery, and the inner peripheral wall of the first adjusting seat 120 has a first groove 121, which can slide and engage with the first protrusion 111 along the axial direction of the sleeve 110; the sleeve 110 has a second protrusion 112 on its outer periphery, and the inner peripheral wall of the second adjusting seat 130 has a second groove 131, which can slide and engage with the second protrusion 112 along the axial direction of the sleeve 110. The first protrusion 111 and the second adjusting seat 130 serve as guides, guiding the first adjusting seat 120 and the second adjusting seat 130 to move along the axial direction of the sleeve 110, while preventing the first adjusting seat 120 and the second adjusting seat 130 from rotating along the circumferential direction of the sleeve 110.

[0037] Furthermore, in one embodiment, the number of first protrusions 111 is configured to be multiple, and the multiple first protrusions 111 are distributed at intervals along the circumference of the sleeve 110. In this way, the force on the first adjusting seat 120 along the circumference of the sleeve 110 is more uniform. Similarly, the number of second protrusions 112 is configured to be multiple, and the multiple second protrusions 112 are distributed at intervals along the circumference of the sleeve 110.

[0038] In one embodiment, the sleeve 110 has a mounting base 180 at one end along its axial direction away from the fixed base 140. The mounting base 180 is used for detachable connection to an external support structure. It should be noted that the external support structure refers to a support structure such as a wall panel or a box.

[0039] Specifically, the mounting base 180 has multiple mounting holes, and the mounting base 180 can be detachably connected to the external support structure via screws and mounting holes.

[0040] The float adjustment mechanism 100 also includes a first rod 191 and a second rod 192. One end of the first rod 191 is detachably connected to the outer peripheral wall of the first adjusting seat 120, and the other end is provided with a first roller 1911, which is used to abut against the outer side of one of the floats 210. One end of the second rod 192 is detachably connected to the outer peripheral wall of the second adjusting seat 130, and the other end is provided with a second roller 1921, which is used to abut against the outer side of the other float 210. In this way, by adjusting the positions of the first adjusting seat 120 and the second adjusting seat 130 along the axial direction of the sleeve 110, the distance between the first roller 1911 and the second roller 1921 can be adjusted, thereby adjusting the angle of the two floats 210 respectively.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
