Description

Technical Field

[0001] This utility model relates to the field of object packaging technology, and in particular to a packing machine conveyor assembly. Background Technology

[0002] As a core piece of equipment in modern logistics packaging, the design of the conveyor structure of a strapping machine directly affects the stability of strapping transport and packaging quality. In a strapping machine, the conveyor front cover, as a key component guiding the movement of the strapping, is typically used in conjunction with the conveyor base plate to ensure that the strapping accurately enters the conveyor along a preset path to complete the strapping operation.

[0003] In traditional conveyor belt cover designs, bends are typically treated with straight surfaces or rounded corners. While this design achieves basic guiding functionality, it has significant drawbacks in practical applications. Specifically, when the strapping machine operates continuously for extended periods or at high speeds, the strapping band frequently passes through the bends of the conveyor belt cover. Due to the small radius of curvature of the rounded corner structure, the contact area between the strapping band and the inner wall of the conveyor belt cover is concentrated when turning, leading to a sharp increase in frictional resistance. This intense localized friction not only accelerates surface wear of the strapping band, generating burrs and even the risk of breakage, but also causes the strapping band to deviate or jam due to obstructed movement, thereby reducing the tightness of the binding and the smoothness of the appearance, affecting the aesthetics and reliability of the packaged product. Although existing technologies have attempted to alleviate wear problems by optimizing material hardness or surface coatings, they have failed to fundamentally improve the negative impact of the conveyor belt cover's geometry on movement resistance. Therefore, we provide a strapping machine conveyor assembly to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 — Figure 6 The example shown.

[0032] participate Figures 1 to 6 As shown in the figure, this application embodiment provides a packing machine conveyor assembly, which includes a base 100, a cover plate 200, and a screwing component 300. The base 100 is at least partially arc-shaped, and a linear groove 110 is formed on one surface of the base 100 along its length. The cover plate 200 is detachably mounted on the base 100 and is adapted to the base 100. The cover plate 200 at least partially closes the linear groove 110 to form a conveyor. An avoidance groove 120 is formed on the side of the base 100 away from the cover plate 200, and the avoidance groove 120 communicates with the linear groove 110. The screwing component 300 passes through the base 100 in the width direction and is fixedly connected to the frame.

[0033] Please see Figures 1 to 3 As shown, this application designs the base 100 to be at least partially arc-shaped, and combines it with the cover plate 200 to close the linear groove 110 to form a conveyor belt, enabling the strapping to move along a continuous, smooth, arc-shaped streamlined path when turning. Compared to traditional small rounded corners or straight surfaces, this arc-shaped structure significantly increases the contact area between the strapping and the inner wall of the conveyor belt, reduces the frictional stress per unit area, and thus reduces surface wear and movement resistance of the strapping.

[0034] Please continue reading. Figures 1 to 3As shown, this application also provides a clearance groove 120 on the base 100, which allows the drive wheel to be positioned in the clearance groove 120. The clearance groove 120 is also connected to the linear groove 110, which allows the drive wheel to be partially positioned in the linear groove 110 and in contact with the packing strap, thereby enabling the conveying of the packing strap in the linear groove 110.

[0035] Furthermore, in order to fix the belt assembly consisting of the base 100 and the cover plate 200, this application uses a screw fastener 300 to fix the base 100 to the frame, thus completing the installation of the assembly.

[0036] The base 100 has at least one through hole 160 extending along its width, and the screwing component 300 passes through the through hole 160 to connect with the frame.

[0037] In this embodiment, the screwing component 300 passes through the through hole 160 and is fixed in place. Specifically, to ensure that the base 100 is fixed to the frame, there are two through holes 160. Correspondingly, the number of through holes 160 can also be three, four, five, etc., and there is no specific limitation. In this embodiment, the screwing component 300 can be a bolt, and the base 100 is fixedly installed on the frame by bolt connection.

[0038] To improve the wear resistance of the inner wall of the linear groove 110, at least one wear-resistant component 400 is provided at a relatively opposite position on the base 100 on both sides of the linear groove 110, and a transition area is formed between the wear-resistant components 400 on both sides. The wear-resistant component 400 includes a receiving groove 410 formed on the base 100. The radial part of the receiving groove 410 is connected to the linear groove 110. Each receiving groove 410 is provided with a wear-resistant block 420, and the wear-resistant block 420 is partially located in the linear groove 110.

[0039] In one embodiment, see Figure 4 As shown, receiving grooves 410 are provided on both sides of the linear groove 110, and each receiving groove 410 is also embedded with a wear-resistant block 420. It can be understood that two wear-resistant components 400 at the same position in the width direction of the linear groove 110 form a group. That is, multiple groups can be arranged at intervals along the length direction of the entire linear groove 110. The specific number is not limited here. In this embodiment, two groups are provided on both sides of the linear groove 110. For details, please refer to [link to relevant documentation]. Figure 3 and Figure 4 As shown.

[0040] Furthermore, in order to prevent the strapping from directly contacting the inner wall of the linear groove 110, the peripheral surface of the receiving groove 410 is connected to the linear groove 110. Correspondingly, the wear-resistant block 420 is also partially located in the linear groove 110. It can be understood that the two wear-resistant blocks 420 in the same group define a transition area for the strapping, which facilitates the passage of the strapping. That is, during the movement, the strapping will contact the peripheral surface of the wear-resistant block 420, but will not directly contact the inner wall of the receiving groove 410 and cause friction.

[0041] For example, both the receiving groove 410 and the wear-resistant block 420 are cylindrical. The arc-shaped wear-resistant block 420 makes it easier for the strapping to move smoothly. The spacing between adjacent wear-resistant blocks 420 on the same side can be 1 / 4 to 1 / 5 of the overall length of the linear groove 110. In order to reduce the friction on the surface of the wear-resistant block 420, cross-shaped oil storage grooves are opened on the circumference of the wear-resistant block 420, and the groove depth can be between 0.02mm and 0.05mm, thereby forming a lubricating oil film and maintaining lubrication.

[0042] In this embodiment, in order to improve the wear resistance of the wear-resistant block 420, the wear-resistant block 420 can be selected as an alloy, specifically a cemented carbide. The specific material can be selected according to actual needs, and no specific limitation is made here.

[0043] It is understood that in this embodiment, the wear-resistant block 420 is used as the wear-resistant body that contacts the packing strap. Compared with the linear groove 110 material, it is more wear-resistant. When the wear-resistant block 420 is worn and needs to be replaced, it can be replaced simply by opening the cover plate (200). The operation is simple and greatly reduces maintenance costs.

[0044] The cover plate 200 includes an arc-shaped plate 210, a straight plate 220 is provided on one side of the arc-shaped plate 210, and a positioning plate 230 is provided between the arc-shaped plate 210 and the straight plate 220. The arc-shaped plate 210, the straight plate 220 and the positioning plate 230 define a connecting groove 240. The connecting groove 240 is located at the position of the clearance groove 120 and is connected to the linear groove 110.

[0045] Please continue reading. Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, in order to drive and transport the packing strapping entering the linear groove 110, the cover plate 200 is composed of three parts. Specifically, the cover plate 200 is mainly composed of an arc plate 210, a straight plate 220, and a positioning plate 230. The three parts surround and define a connecting groove 240 at the clearance groove 120 position. The connecting groove 240 is connected to the linear groove 110, so that another roller can pass through the connecting groove 240 and be located in the linear groove 110, thereby contacting the packing strapping in the linear groove 110. It should be noted that the packing strapping in the linear groove 110 is moved and transported by the cooperation of the rollers at the clearance groove 120 position and the connecting groove 240 position. That is, the packing strapping contacts the surfaces of the two rollers, and when the two rollers rotate at the same time, they drive the packing strapping located between them to be transported and moved in the linear groove 110.

[0046] In this embodiment, the clearance groove 120 divides the linear groove 110 into an arc segment 111 and a straight segment 112. The arc segment 111 is located at the position of the arc plate 210, and the straight segment 112 is located at the position of the straight plate 220.

[0047] Please see Figures 1 to 3 As shown, the surface of the base 100 at position 111 of the arc segment is an arc surface, and the surface of the linear groove 110 at position 112 of the straight segment is a straight surface. Furthermore, a curved surface transition is used between the arc surface and the straight surface to reduce the impact of excessive curvature on the packing strap. It should be noted that the straight surface mentioned above refers to a surface that appears straight when viewed from the side; if placed horizontally, it is a horizontal surface.

[0048] The opening of the straight segment 112 gradually increases in the direction away from the arc segment 111.

[0049] Please see Figure 3 As shown, the opening of the straight segment 112 gradually increases in size from the straight segment 112 away from the arc segment 111. Specifically, the opening of the straight segment 112 is approximately "V" shaped when viewed from above. The purpose of this design is to facilitate the entry of the packing strap into the linear groove 110 and to provide sufficient space for the packing strap to enter the linear groove 110.

[0050] At least one first mounting hole 130 is provided on the surface of the base 100 in the section where the arc plate 210 is located. A first through hole 211 is provided through the arc plate 210. A first fixing member 212 is provided at the position of the first through hole 211. The first fixing member 212 is used to fix the arc plate 210 to the base 100. The first fixing member 212 passes through the first through hole 211 and is connected to the first mounting hole 130.

[0051] See Figure 3As shown, the arc plate 210 is located at the position of the arc segment 111, that is, the curvature of the arc plate 210 is the same as the surface of the base 100, so that the linear groove 110 can be closed by the arc plate 210. Specifically, at least one first mounting hole 130 is opened on the surface of the base 100 facing the arc plate 210, and then a first through hole 211 corresponding to the number and position of the first mounting hole 130 is opened on the arc plate 210. Next, in order to fix the arc plate 210 to the base 100, the first fixing member 212 passes through the first through hole 211 to the first mounting hole 130, and then the first fixing member 212 is screwed into the first mounting hole 130 to fix the arc plate 210 to the base 100.

[0052] In this embodiment, in order to fully fix the arc plate 210 to the linear groove 110, the number of the first mounting hole 130, the first through hole 211, and the first fixing member 212 are all two, thereby achieving the fixation of the arc plate 210. In other embodiments, the number of the first mounting hole 130, the first through hole 211, and the first fixing member 212 can also be three, four, five, etc., and the specific number is not limited here.

[0053] Preferably, the first mounting hole 130 can be formed on both sides of the linear groove 110, and correspondingly, the first through hole 211 can be formed on both sides of the arc plate 210, corresponding to the position of the first mounting hole 130.

[0054] At least one second mounting hole 140 is provided on the surface of the base 100 in the section where the straight plate 220 is located. A second through hole 221 is provided through the straight plate 220. A second fixing member 222 is provided at the location of the second through hole 221. The second fixing member 222 is used to fix the straight plate 220 to the base 100. The second fixing member 222 passes through the second through hole 221 and is connected to the second mounting hole 140.

[0055] Please continue reading. Figure 3 As shown, the straight plate 220 is located at the position of the straight segment 112, that is, the surface of the straight plate 220 facing the straight segment 112 is a straight surface. Similar to the arc plate 210, the straight plate 220 is also used to close the arc segment 111. Specifically, the second fixing member 222 passes through the second through hole 221 to the second mounting hole 140. The connection between the second fixing member 222 and the second mounting hole 140 realizes the fixing of the straight plate 220 and the base 100 and the closure of the straight segment 112.

[0056] Furthermore, in this embodiment, there are two of each of the second mounting hole 140, the second through hole 221, and the second fixing member 222, which ensures that the position of the straight plate 220 does not shift and that it can be stably fixed to the base 100.

[0057] A third mounting hole 150 is provided on the surface of the base 100 at the location of the positioning plate 230. A third through hole 231 is provided on the positioning plate 230. A third fixing member 232 is provided at the location of the third through hole 231. The third fixing member 232 is used to fix the positioning plate 230 to the base 100. The third fixing member 232 passes through the third through hole 231 and is connected to the third mounting hole 150.

[0058] Please continue reading. Figure 3 As shown, in order to ensure that the curved plate 210 is installed in the correct position, the positioning plate 230 is first installed on the base 100 before the curved plate 210 is installed. When the curved plate 210 needs to be installed, it only needs to be abutted against the positioning plate 230 to achieve the positioning and installation. Specifically, when the positioning plate 230 needs to be installed, the third fixing member 232 is first inserted through the third through hole 231 into the third mounting hole 150, thereby achieving the fixed installation of the positioning plate 230.

[0059] It should be noted that in this embodiment, both the first through hole 211 and the third through hole 231 are elongated oval grooves. It can be understood that the positions of the first through hole 211 and the third through hole 231 are elongated oval grooves and can be adjusted as needed to ensure that the installation position of the arc plate 210 meets the installation requirements, thereby facilitating the installation and adjustment of the arc plate 210.

[0060] In this embodiment, the first fixing member 212, the second fixing member 222 and the third fixing member 232 mentioned above are all screws or bolts, and the corresponding first mounting hole 130, second mounting hole 140 and third mounting hole 150 are all threaded holes.

[0061] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
