Description

Technical Field

[0001] The utility model relates to the technical field of glue extracting machines, in particular to a clutch structure of a needle-piercing glue extracting device. Background Art

[0002] In the existing rubber extraction technology, a rubber extraction machine is used to cut the bark of the rubber tree to make the rubber sap flow out, thereby completing the rubber extraction work.

[0003] When the rubber tapping machine completes a full stroke, it is necessary to reset the rubber tapping machine for reuse. In order to meet this operational requirement, it is necessary to provide a mechanical mechanism that facilitates the reset of the rubber tapping machine. Utility Model Content

[0004] The problem solved by the utility model is how to facilitate the reset of a rubber tapping machine.

[0005] To address the aforementioned issues, the present invention provides a clutch structure for a needle-piercing adhesive extraction device, comprising: a transmission tooth, a traveling tooth, a transmission rod, and a locking member. The transmission rod is movably connected to the transmission tooth; the traveling tooth is in transmission connection with the transmission tooth via the transmission rod; and the locking member is disposed on the transmission rod. The locking member and the traveling tooth can have a first locking state and a second locking state. In the first locking state, the locking member engages with the traveling tooth; in the second locking state, the locking member and the traveling tooth are disconnected.

[0006] Compared with the existing technology, the technical effect achieved by this technical solution is as follows: the transmission teeth are connected to the main body of the needle-punched glue extracting device, the transmission teeth realize the transmission of the traveling teeth through the transmission rod, the traveling teeth are engaged with the guide rails of the needle-punched glue extracting machine, and the transmission rod is movably connected to the transmission teeth to realize the conversion of the locking member between the first locking state and the second locking state, thereby realizing the transmission state and separation state of the locking member and the traveling teeth. When the glue extracting machine is working normally, the locking member is often in the first locking state. When the user needs to reset the glue extracting machine, the transmission rod is moved to put the locking member in the second locking state. At this time, the transmission between the transmission teeth and the traveling teeth is disconnected, and the traveling teeth can move independently along the guide rails. At this time, the user can move the needle-punched glue extracting device to complete the reset of the needle-punched glue extracting device without triggering the needle-punching device.

[0007] Furthermore, the transmission rod is provided with a fixed surface structure, which is arranged axially along the transmission rod; a first mounting position that cooperates with the fixed surface is provided on the transmission tooth; the transmission rod cooperates with the first mounting position to limit the circumferential movement of the transmission rod.

[0008] Compared to the existing technology, this technical solution achieves the following technical effects: the fixed surface structure is arranged along the axial direction of the transmission rod. When it cooperates with the transmission teeth, it can restrict the circumferential rotation of the transmission rod while ensuring that the transmission rod can move along the axial direction in the first installation position. When the transmission teeth rotate, they can also drive the transmission rod to rotate, thereby realizing the transmission of the traveling gear in the first locked state.

[0009] Furthermore, the locking member is detachably connected to the transmission rod.

[0010] Compared with the prior art, the technical effect achieved by this technical solution is that when the locking member is damaged or partially fails, the locking member can be disassembled and replaced without replacing the entire clutch assembly.

[0011] Furthermore, a second installation position is provided in the axial direction of the locking member; the transmission rod is sleeved and matched with the second installation position to realize the installation of the locking member.

[0012] Compared with the existing technology, the technical effect achieved by this technical solution is: realizing the connection between the locking member and the transmission rod.

[0013] Furthermore, the clutch structure of the needle-puncture glue extraction device provided by the present invention also includes: a fastener; a third mounting position is provided in the radial direction of the transmission rod; and a fourth mounting position is provided in the radial direction of the locking member; wherein the fastener cooperates with the third mounting position and the fourth mounting position to limit the circumferential and axial movement of the locking member.

[0014] Compared with the existing technology, the technical effect achieved by this technical solution is: it can fix the locking piece on the transmission rod, further limit the locking piece, and limit the axial movement of the locking piece on the transmission rod to ensure the locking piece's bite effect on the traveling teeth.

[0015] Furthermore, the fastener has an elastically deformable structure.

[0016] Compared with the existing technology, the technical effect achieved by this technical solution is: when installing the fastener, the fastener should be in a slightly deformed state to cooperate with the third installation position and the fourth installation position. After the installation is completed, the fastener returns to its original state by itself, pressing against the third installation position and the fourth installation position, and tightening the connection between the locking piece and the transmission rod.

[0017] Furthermore, the clutch structure of the needle-piercing glue extraction device provided by the present invention further includes: an elastic member that abuts against the transmission rod.

[0018] Compared with the existing technology, the technical effect achieved by this technical solution is: it can ensure that when the glue dispenser is in working state, the locking part is always in the first locking state and is not easy to fall out accidentally. At the same time, it can also provide protection for the locking part when the walking part is overloaded.

[0019] Furthermore, a first engaging portion is provided on the traveling tooth; a second engaging portion is provided on the locking member; and in the first locking state, the first engaging portion and the second engaging portion are at least partially engaged with each other.

[0020] Compared with the existing technology, the technical effect achieved by this technical solution is: strengthening the bite effect between the locking member and the traveling teeth.

[0021] Furthermore, the clutch structure of the needle-piercing glue extraction device provided by the utility model also includes: an abutment body, which is provided with a limiting space; one end of the transmission rod cooperates with the limiting space to fix the axial position of the transmission rod; an elastic member is provided in the limiting space, one end of the elastic member is in abutment contact with the transmission rod, and the other end is in abutment contact with the abutment body.

[0022] Compared with the existing technology, the technical effect achieved by this technical solution is: it facilitates the abutment of the elastic part, so that the elastic part can better provide fixation and protection for the transmission rod, and at the same time limits the transmission rod in the axial direction to prevent the transmission rod from deviating from the axial direction when moving.

[0023] Furthermore, the clutch structure of the needle-piercing glue extraction device provided by the utility model also includes: a sleeve, which is arranged between the transmission tooth and the traveling tooth, and the sleeve is relatively movably sleeved on the locking member; a convex portion is provided on the side of the transmission tooth close to the traveling tooth, one end of the sleeve is sleeved and matched with the convex portion, and the other end is sleeved and matched with the first engaging portion.

[0024] Compared with the existing technology, the technical effect achieved by this technical solution is: the transmission rod and the locking member are further limited and protected as a whole by the sleeve locking member. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The purpose of the utility model is to provide a clutch structure of a needle-piercing glue-taking device, which is used to facilitate the reset of the glue-taking machine.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the present invention provides a clutch structure for a needle-piercing glue extraction device, comprising: a transmission tooth 1, a traveling tooth 3, a transmission rod 2, and a locking member 4. The transmission rod 2 is movably connected to the transmission tooth 1; the traveling tooth 3 is transmission-connected to the transmission tooth 1 via the transmission rod 2; the locking member 4 is provided on the transmission rod 2, and the locking member 4 and the traveling tooth 3 can have a first locking state and a second locking state. In the first locking state, the locking member 4 is engaged with the traveling tooth 3; in the second locking state, the locking member 4 is disconnected from the traveling tooth 3.

[0033] The transmission tooth 1 is connected to the main body of the needle-punched glue extracting device through transmission. The transmission tooth 1 transmits the travel tooth 3 through the transmission rod 2. The travel tooth 3 engages with the guide rail of the needle-punched glue extracting machine (not shown in the figure). The transmission rod 2 is movably connected to the transmission tooth 1 to realize the conversion of the locking member 4 between the first locking state and the second locking state, thereby realizing the transmission state and separation state of the locking member 4 and the travel tooth 3. When the glue extracting machine is working normally, the locking member 4 is often in the first locking state. When the user needs to reset the glue extracting machine, the transmission rod 2 is moved to put the locking member 4 in the second locking state. At this time, the transmission between the transmission tooth 1 and the travel tooth 3 is disconnected, and the travel tooth 3 can move independently along the guide rail. At this time, the user can move the needle-punched glue extracting device to complete the reset of the needle-punched glue extracting device without triggering the needle-punching device.

[0034] Specifically, moving the transmission rod 2 refers to moving the transmission rod 2 along the axial direction toward the transmission tooth 1 .

[0035] like Figure 2 As shown, the transmission rod 2 is provided with a fixed surface structure 21, which is arranged axially along the transmission rod 2; a first mounting position 11 is provided on the transmission tooth 1 to cooperate with the fixed surface; the transmission rod 2 cooperates with the first mounting position 11 to limit the circumferential movement of the transmission rod 2.

[0036] The fixed surface structure 21 is arranged along the axial direction of the transmission rod 2. When cooperating with the transmission tooth 1, it can limit the circumferential rotation of the transmission rod 2 while ensuring that the transmission rod 2 can move along the axial direction in the first mounting position 11. When the transmission tooth 1 rotates, it can also drive the transmission rod 2 to rotate, thereby realizing the transmission of the traveling tooth 3 in the first locked state.

[0037] Continue to refer to Figure 2 , the locking member 4 is detachably connected to the transmission rod 2.

[0038] The detachable arrangement of the locking member 4 enables the locking member 4 to be detached and replaced when the locking member 4 is damaged or partially malfunctions, without having to replace the entire clutch assembly.

[0039] Continue to refer to Figure 2 The locking member 4 is provided with a second installation position 41 in the axial direction; the transmission rod 2 is sleeved and matched with the second installation position 41 to realize the installation of the locking member 4.

[0040] The connection between the locking member 4 and the transmission rod 2 is achieved by the cooperation between the transmission rod 2 and the second installation position 41 .

[0041] The clutch structure of the needle-puncture glue extraction device provided by the present invention also includes: a fastener 5; a third mounting position 22 is provided in the radial direction of the transmission rod 2; a fourth mounting position 42 is provided in the radial direction of the locking member 4; wherein the fastener 5 cooperates with the third mounting position 22 and the fourth mounting position 42 to limit the circumferential and axial movement of the locking member 4.

[0042] Specifically, in this embodiment, the fastener 5 is a hollow cylindrical structure.

[0043] The fastener 5 can fix the locking member 4 on the transmission rod 2 and further limit the locking member 4 to restrict the axial movement of the locking member 4 on the transmission rod 2 to ensure the engagement effect of the locking member 4 on the traveling gear 3.

[0044] like Figure 3 As shown, the fastener 5 has an elastically deformable structure.

[0045] Specifically, the elastically deformable structure is an unclosed gap on the hollow cylindrical locking member 4. When the user applies force along the radial direction of the cylinder with his fingers, the fastener 5 can be deformed, making it easier to install it into the third installation position 22 and the fourth installation position 42.

[0046] When installing the fastener 5, the fastener 5 should be in a slightly deformed state to cooperate with the third mounting position 22 and the fourth mounting position 42. After the installation is completed, the fastener 5 will return to its original state by itself, pressing against the third mounting position 22 and the fourth mounting position 42, and tightening the connection between the locking member 4 and the transmission rod 2.

[0047] Refer again Figure 2 The clutch structure of the needle-piercing glue extraction device provided by the present invention further includes an elastic member 6. The elastic member 6 is in contact with the transmission rod 2.

[0048] Specifically, in this embodiment, the elastic member 6 is a spring.

[0049] The elastic member 6 can ensure that when the glue dispenser is in operation, the locking member 4 is always in the first locking state and is not easy to fall out accidentally. At the same time, it can also provide protection for the locking member 4 when the walking member is overloaded.

[0050] like Figure 3 As shown, the traveling tooth 3 is provided with a first bite portion 31; the locking member 4 is provided with a second bite portion 43; in the first locking state, the first bite portion 31 and the second bite portion 43 are at least partially engaged with each other.

[0051] In this embodiment, a slope structure is provided on each engaging tooth of the first engaging portion 31 and the second engaging portion 43 to ensure the engaging effect while facilitating the locking member 4 to disengage from the traveling tooth 3 when the traveling tooth 3 is overloaded.

[0052] By providing the first engaging portion 31 and the second engaging portion 43 , the engaging effect between the locking member 4 and the traveling tooth 3 is enhanced.

[0053] Refer again Figure 2 The clutch structure of the needle-piercing glue extraction device provided by the present invention also includes: an abutment body 61, which is provided with a limiting space 611; one end of the transmission rod 2 cooperates with the limiting space 611 to fix the axial position of the transmission rod 2; the elastic member 6 is provided in the limiting space 611, one end of the elastic member 6 is in abutment contact with the transmission rod 2, and the other end is in abutment contact with the abutment body 61.

[0054] The abutment body 61 facilitates the abutment of the elastic member 6 , so that the elastic member 6 can better fix and protect the transmission rod 2 , while limiting the transmission rod 2 in the axial direction to prevent the transmission rod 2 from deviating from the axial direction when moving.

[0055] Refer again Figure 1 The clutch structure of the needle-piercing glue extraction device provided by the utility model also includes: a sleeve 62, which is arranged between the transmission tooth 1 and the traveling tooth 3, and the sleeve 62 is relatively movably sleeved on the locking member 4; a convex portion 12 is provided on the side of the transmission tooth 1 close to the traveling tooth 3, one end of the sleeve 62 is sleeved and matched with the convex portion 12, and the other end is sleeved and matched with the first bite portion 31.

[0056] The sleeve 62 further limits and protects the transmission rod 2 and the locking member 4 as a whole by being sleeved on the locking member 4.

[0057] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
