[0041] The present application discloses a portable electric reciprocating rubber tapping machine, which includes a housing, a drive mechanism and a transmission structure. The drive mechanism is arranged in the housing, and the drive mechanism includes a drive motor and a reduction device. The drive motor is mechanically connected to the reduction device, and the reduction device is arranged at the output end of the drive motor; the transmission structure is partially arranged in the housing and connected to the output end of the reduction device. One end of the transmission structure away from the drive mechanism extends to the outside of the housing and is used to connect to a tool holder. The transmission structure is used to drive the tool holder to move. The engagement of the drive motor and the reduction device in the drive mechanism in the present application plays a role in increasing torque and reducing noise, which is beneficial to improving the cutting accuracy of the rubber tapping machine.

[0042] Next join Figures 1-6 To describe a portable electric reciprocating rubber tapping machine provided in an embodiment of the present application, the rubber tapping machine not only has low noise during operation, but also has good cutting accuracy.

[0043] The portable electric reciprocating rubber tapping machine comprises a housing 10, a driving mechanism and a transmission structure 30.

[0044] The drive mechanism 20 is disposed in the housing 10 and includes a drive motor 21 and a reduction gear 22. The drive motor 21 is mechanically connected to the reduction gear 22, and the reduction gear 22 is disposed at the output end of the drive motor 21.

[0045] The transmission structure 30 is partially arranged in the shell 10 and is connected to the output end of the reduction device 22. The end of the transmission structure 30 away from the driving mechanism 20 extends outside the shell 10 and is used to connect to the tool holder (not shown in the drawings). The transmission structure 30 is used to drive the tool holder to move.

[0046] It should be noted that in the present application, a reduction gear (such as a reduction box of a planetary gear combination) is configured at the output end of the drive motor. The reduction gear decelerates and increases the torque output by the drive motor and outputs it, which is beneficial to improve the time for piercing the rubber tree. After deceleration, the driving torque is large, which is convenient for piercing the rubber tree, thereby improving the tapping accuracy of the portable electric reciprocating rubber tapping machine; at the same time, by configuring the reduction gear, the vibration of the drive motor operation is reduced, thereby improving the safety and noise reduction performance of the portable electric reciprocating rubber tapping machine.

[0047] refer to Figure 3-Figure 5 In a specific embodiment, the housing 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are fixedly connected by screws 111; after the first housing 11 and the second housing 12 are connected, they are used to support and fix the drive mechanism and the transmission structure. After the first housing 11 and the second housing 12 are connected, there is an accommodating space, and the accommodating space can provide corresponding installation space for the drive mechanism 20 and the transmission structure 30, which facilitates the installation and disassembly of the drive mechanism. Further, with reference to Figure 1 The shell 10 is cylindrical and is divided into a first section 111, a second section 121 and a third end 131 along its length, wherein the diameter of the second section 121 is smaller than that of the first section 111 and the third section 131. The second section 121 is a gripping section, which makes it easier for the operator to grip the shell and prevent it from falling off during operation.

[0048] In a specific embodiment, the driving motor 21 in the present application is a brushless motor.

[0049] refer to Figure 2-Figure 6In a specific embodiment, the reduction gear is coaxially arranged with the driving motor, and the reduction gear includes a reduction box, a reduction gear assembly (not shown in the drawings) and a rotating shaft 223. The reduction gear assembly is arranged in the reduction box, one end of the reduction gear assembly is connected to the output end of the driving motor 21, and the other end is connected to the rotating shaft 223; the rotating shaft 223 extends to the outside of the reduction box away from the reduction gear assembly and is connected to the transmission structure 30; wherein the reduction box includes a box body 221 and a box cover 222, and the box cover 222 and the box body 221 are fixedly connected by fasteners, wherein the fasteners specifically refer to screws. It is provided with at least one first protrusion 2221 extending along its radial direction, and the shell 10 is provided with a first recessed portion 14 adapted to the first protrusion 2221; the box body 221 is provided with at least one second protrusion 2211 extending along its radial direction, and the shell 10 is provided with a second recessed portion 13 adapted to the second protrusion 2211. This design prevents the reduction gear box from shaking during the operation of the driving motor, and by providing the first protrusion 2221 and the second protrusion 2211, the reduction gear is clamped in the shell 10, which not only simplifies the installation steps, but also facilitates subsequent disassembly and installation.

[0050] Furthermore, the axis a of the first protrusion 2221 is perpendicular to the axis b of the second protrusion 2211. This design can fix the reduction gearbox with force from multiple directions to prevent the reduction gearbox from moving when the drive motor 21 is running.

[0051] refer to Figure 1-Figure 3 In a specific embodiment, a plurality of first heat dissipation holes 211 are respectively provided on the end surface and the circumference of the drive motor 21 on the side close to the reduction gear. The housing 10 is provided with second heat dissipation holes 16 at the first heat dissipation holes 211 on the circumference corresponding to the circumference. The housing 10 is provided with third heat dissipation holes 17 on the end corresponding to the drive motor 21 away from the reduction gear. By providing at least one first heat dissipation hole 211 on the drive motor, it is beneficial to dissipate the heat in the drive motor 21. At the same time, the second heat dissipation holes 16 are connected to the first heat dissipation holes 211, which is beneficial to transfer the heat in the drive motor 21 to the outside of the housing 10. At the same time, by providing the third heat dissipation holes 17, the heat emitted by the drive motor 21 can be further transferred, thereby preventing the operator from getting hot due to the high temperature of the drive motor when using the portable electric reciprocating rubber tapping machine.

[0052] refer to Figure 1 In a specific embodiment, a gear shift button assembly 15 is configured on the housing 10, and the gear shift button assembly 15 is electrically connected to the control module, and the control module is electrically connected to the drive motor 21, wherein the gear shift button assembly includes a gear button for learning. By setting the gear button for learning for rubber tapping beginners, the safety of the beginners is improved.

[0053] Continue to refer Figure 1In one embodiment, the portable electric reciprocating rubber tapping machine further includes a control panel assembly, which is used to control the operation of the drive motor and the operation of the entire portable electric reciprocating rubber tapping machine. The control panel assembly includes a battery box body (not shown in the accompanying drawings) and a connecting wire 40, one end of the connecting wire is connected to the end of the drive motor 21 away from the reduction gearbox, and the other end is provided with a connection port adapted to the battery box body. By providing the connection port, a detachable connection between the portable electric reciprocating rubber tapping machine and the battery box can be achieved, which is not only convenient for storage and transportation, but also allows the portable electric reciprocating rubber tapping machine to be connected to different battery boxes. In this embodiment, the battery box body is placed outside the housing, which is conducive to reducing the weight in the housing 10 of the portable electric reciprocating rubber tapping machine, and relative to the battery box body placed in the housing 10, the external battery box body has a larger capacitance, meeting the needs of actual production.

[0054] refer to Figure 2 and Figure 6 In a specific embodiment, the transmission structure 30 includes a camshaft 31 and a transmission member 32. The camshaft 31 is connected to the output end of the reduction gear 22, specifically the camshaft 31 is connected to the output end of the rotating shaft 223. The camshaft 31 is provided with a clamping portion adapted to the output end of the rotating shaft 223. The output end of the rotating shaft 223 is inserted into the clamping portion and then fixed by a retaining spring. The transmission member 32 is slidably arranged in the housing 10, and the end of the transmission member 32 away from the camshaft 31 extends to the outside of the housing 10 for connection with the tool holder. Furthermore, at least one bearing ring 313 is provided on the camshaft 31. The bearing ring 313 is clamped and arranged in the housing. The bearing ring 313 is provided on the camshaft 31 for supporting and fixing the camshaft to prevent the camshaft from shaking during rotation. Specifically, the camshaft 31 includes a shaft section 311 and a cam section 312. The bearing ring 313 is provided on the shaft section. 311 is close to the side of the cam segment 312. In a preferred embodiment, the camshaft is configured with two bearing rings, at least one of which is a ball bearing; in the first state (i.e., the portable electric reciprocating rubber tapping machine is not in use), the camshaft and the transmission member are separated; in the second state (i.e., the portable electric reciprocating rubber tapping machine is in use), the camshaft is connected to the transmission member, and the rotation of the camshaft drives the transmission member to reciprocate, which is specifically a reciprocating linear motion. Since the cam segment has a protrusion (not shown in the accompanying drawings) and a flat portion (not shown in the accompanying drawings), the transmission member is connected (abutted) to the flat portion in the initial state. As the camshaft rotates, the transmission member will connect (abut) with the protrusion, thereby pushing the tool holder on the transmission member further forward to tap the rubber trees. As the camshaft rotates over and over again, the transmission member is driven to connect with the flat portion and the protrusion respectively, so that the tool holder can tap the rubber trees.
