DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention.

[0031] like Figures 1 to 5 The tool sleeve chain transmission guide assembly shown includes: a main body frame 1, and a driving wheel 2 and a driven wheel 3 arranged at both ends of the main body frame 1;

[0032] The main body frame 1 is provided with guide channels 1a on both sides along the length direction. The driving wheel 2 is provided with a first annular groove 2a along the circumference direction, and the driven wheel 3 is provided with a second annular groove 3a along the circumference direction. The first annular groove 2a and the second annular groove 3a are connected to the two guide channels 1a on both sides of the main body frame 1, forming a channel for the intermediate roller 20 to pass through.

[0033] Two guide plates 4 corresponding to the two side rollers 10 on the tool sleeve chain are provided on the two side surfaces of the main body frame 1 at positions corresponding to the guide channels 1a. The two guide plates 4 and the side surfaces of the main body frame 1 form track grooves for the transmission of the side rollers 10.

[0034] Specifically, the knife sleeve chain is transmitted in the track groove formed by the guide plate 4 through the side rollers 10 thereon, and at the same time, the intermediate roller 20 is passed through the first annular groove 2a and the second annular groove 3a of the driving wheel 2 and the driven wheel 3, as well as the guide channel 1a of the main body frame 1, to realize stable transmission of the chain.

[0035] In the present invention, the guide channel 1a and the track groove work together to provide a clear transmission track for the side rollers 10 and the middle roller 20, thereby reducing the shaking problem caused by the elongation of the chain, improving the stability of the transmission, and effectively ensuring the positioning accuracy of the tool changing point on the tool sleeve chain.

[0036] In the present invention, the two end edges of the driving wheel 2 extend to form two supporting edges, and the supporting edges are provided with a plurality of semi-circular arc grooves 21 for accommodating the side rollers 10 along the circumferential direction, and the plurality of semi-circular arc grooves 21 are arranged at equal intervals;

[0037] The plurality of semicircular arc grooves 21 on the two supporting edges are arranged in a one-to-one correspondence.

[0038] When the driving wheel 2 rotates, the semicircular arc groove 21 on it will drive the side roller 10 on the chain to roll, thereby driving the entire chain to transmit. The close fit between the semicircular arc groove 21 and the side roller 10 reduces the friction and wear between the chain and the driving wheel 2, improves the efficiency and life of the transmission, and helps the chain maintain a high positioning accuracy during the transmission process.

[0039] As a preference of the above embodiment, the distance between the two supporting edges is greater than the width of the chain plate of the tool sleeve chain.

[0040] When the side roller 10 is embedded in the semicircular arc groove 21, the chain plate of the tool sleeve chain is placed between the two supporting edges to ensure the feasibility of transmission.

[0041] In the preferred embodiment of the present invention, a gap is reserved between the end surface of the intermediate roller 20 and the bottom of the first annular groove 2a.

[0042] The reserved gap allows the intermediate roller 20 to have a certain amount of space to move in the first annular groove 2a, which can accommodate slight displacements caused by factors such as manufacturing errors, installation errors or thermal expansion, thereby reducing direct contact between the intermediate roller 20 and the bottom of the first annular groove 2a, thereby reducing friction resistance.

[0043] In the present invention, the driven wheel 3 includes a mounting plane 31 connected to the main frame 1 and a semicircular surface 32 for the tool sleeve chain to transmit. The mounting plane 31 ensures that the driven wheel 3 can be stably fixed in the transmission system, while the semicircular surface 32 corresponds to the first annular groove 2a of the driving wheel 2, together forming the transmission path of the chain.

[0044] Based on the above embodiment, the semicircular surface 32 has guide arcs at both edges that roll in contact with the two side rollers 10, guiding the side rollers 10 along a predetermined trajectory and ensuring stable chain transmission. A clearance groove is provided between the two guide arcs, providing additional space to prevent interference or jamming caused by tension changes or other factors during chain transmission.

[0045] As a preferred embodiment of the above embodiment, the mounting plane 31 is provided with a groove, and the bottom surface of the body frame 1 is provided with a protrusion that cooperates with the groove. The tight fit between the groove and the protrusion can effectively prevent the body frame 1 from loosening on the mounting plane 31.

[0046] In a preferred embodiment, the guide plate 4 is fixed to one side of the main frame 1 via a plurality of struts 5, with the struts 5 being located on the side of the guide plate 4 away from the guide channel 1a. This prevents the struts 5 from obstructing the guide channel 1a, allowing the side rollers 10 to pass through the guide channel 1a smoothly and accurately.

[0047] In a preferred embodiment, the distance between the guide plate 4 and the side of the main frame 1 is greater than the diameter of the side roller 10. When the distance between the guide plate 4 and the side of the main frame 1 is large enough, the side roller 10 can roll smoothly therein, reducing energy loss and improving the operating efficiency of the system.

[0048] In the preferred embodiment of the present invention, the main body frame 1 includes two side panels 11 and a back panel 12 connecting the two side panels 11;

[0049] A supporting partition 13 is provided in the semi-enclosed space enclosed by the back plate 12 and the two side plates 11, and a plurality of supporting partitions 13 are provided along the transmission direction of the knife sheath chain; they jointly bear the external load, thereby improving the bearing capacity of the frame and enhancing the overall stability of the main body frame 1;

[0050] The support partition 13 is provided with an avoidance groove 13a at the position of the guide channel 1a. The avoidance groove 13a prevents the knife sleeve chain from being hindered by the partition during the transmission process, thereby ensuring the stability and accuracy of the transmission.

[0051] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
