Detailed implementation mode

[0024] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0025] Example 1, referring to Figures 1 to 2 , which is the first embodiment of the present invention. This embodiment provides a conveying device for the production of plastic-steel belts, which can realize the conveying of plastic-steel belts and limit and guide plastic-steel belts with different width dimensions. It includes a conveying roller mechanism 100 and a guiding mechanism 200.

[0026] Specifically, the conveying roller mechanism 100 is used to convey the plastic-steel belt.

[0027] The guiding mechanism 200 includes two connecting plates 201 fixed on both sides of the conveying roller mechanism 100. An outer cylinder 202 is fixed between the two connecting plates 201. A rotatable inner cylinder 203 is installed inside the outer cylinder 202. A main adjustment groove 204, a first partition groove 205 and a second partition groove 206 are sequentially provided on the outer side surface of the inner cylinder 203. The main adjustment groove 204, the first partition groove 205 and the second partition groove 206 are all symmetrically arranged with respect to the inner cylinder 203. At the same time, partition rods 207 are movably embedded in the main adjustment groove 204, the first partition groove 205 and the second partition groove 206. Thus, by means of the partition rods 207 sequentially arranged in the above-mentioned grooves, and relying on the gap between two adjacent partition rods 207, the placement of the plastic-steel belt is completed and the plastic-steel belt is guided during the transmission process, avoiding the plastic-steel belt from shifting and skewing. And a horizontally arranged positioning groove 202a is provided on the outer wall of the outer cylinder 202, and the partition rod 207 penetrates through the positioning groove 202a. The positioning groove 202a can guide the movement of the partition rod 207 to ensure that the partition rod 207 can only move horizontally along it, meeting the need for subsequent adjustment of the distance between the partition rods 207.

[0028] The first partition groove 205 includes a first inclined groove 205a and a first compensation groove 206b communicating therewith, the second partition groove 206 includes a second inclined groove 206a and a second compensation groove 206b communicating therewith. The main adjustment groove 204, the first inclined groove 205a and the second inclined groove 206a are all inclined, and the first compensation groove 205b and the second compensation groove 206b are both vertically arranged.

[0029] Preferably, the projection lengths of the adjustment groove, the first partition groove 205 and the second partition groove 206 in the circumferential direction of the inner cylinder 203 are the same, and the starting points and ending points of the three coincide, so as to ensure that when the respective partition rods 207 are located at the same side ends of different notches, they are on the same horizontal plane. Initially, the partition rods 207 located inside the first partition groove 205 and the second partition groove 206 are respectively inside the starting ends of the first compensation groove 205b and the second compensation groove 206b. At this time, the distance between the partition rods 207 located inside the main adjustment groove 204 represents the maximum size that can guide the plastic-steel belt. As the inner cylinder 203 rotates, the partition rods 207 in the corresponding notches move relatively inside the notches. When the partition rods 207 are in the first compensation groove 205b or the second compensation groove 206b, their positions remain unchanged. However, for the partition rods 207 located inside the two main adjustment grooves 204, due to the inclined arrangement of the main adjustment groove 204, as the inner cylinder 203 rotates, they move inward along the positioning groove 202a in an opposite direction. Thus, the distance between the two inner partition rods 207 starts to shorten. When the partition rods 207 located inside the compensation groove move relatively to the connection end of the inclined groove and the compensation groove, as the inner cylinder 203 continues to rotate, they can be respectively pushed by the inclined first inclined groove 205a and the second inclined groove 206a and move synchronously towards the middle section of the inner cylinder 203 with the partition rods 207 located inside the main adjustment groove 204. Thus, the distance between adjacent partition rods 207 tends to be adjusted synchronously, and at the same time, the plastic-steel belt placement positions formed between adjacent partition rods 207 gradually increase. It should be noted that the inclination angles of the first inclined groove 205a, the second inclined groove 206a and the main adjustment groove 204 are all different. Thus, when the inner cylinder 203 rotates by a certain angle, through the inclined settings of the three with different angles, the moving distances of the partition rods 207 located inside the three increase in multiples. That is, the moving distance of the partition rods 207 arranged successively outward in the middle section of the inner cylinder 203 is three times the moving distance of the previous one, so as to ensure that the distance between two adjacent partition rods 207 can always be kept consistent with the rotation adjustment of the inner cylinder 203, meeting the placement requirements of the plastic-steel belt.

[0030] During use, the user rotates the inner cylinder 203 counterclockwise according to the size of the plastic-steel belt to adjust the distance between the partition rods 207. After the adjustment is completed, place the plastic-steel belt between the partition rods 207, and then start the conveying roller mechanism 100 to realize the production conveyance of the plastic-steel belt.

[0031] In summary, through the cooperating settings of the main adjustment groove 204, the first partition groove 205 and the second partition groove 206 with the partition rod 207 respectively, during the rotation of the inner cylinder 203, the adjustment of the distance between the partition rods 207 can be realized, and the distance between the partition rods 207 can be kept consistent during the adjustment, and the placement guiding positions of the plastic-steel belts between the partition rods 207 can be increased. This enables the guiding mechanism 200 to guide and limit plastic-steel belts of different sizes, and at the same time, can make the best use of the guiding width of the guiding mechanism 200 to realize the synchronous guiding of multiple plastic-steel belts, reducing the usage limitations of the device and meeting the usage requirements of users in different situations.

[0032] Embodiment 2. Refer to Figures 1 to 4 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a control mechanism 300 for the conveying device used in the production of plastic-steel belts, which solves the problem of inconvenient positioning after the guiding adjustment of the guiding mechanism 200.

[0033] Specifically, the control mechanism 300 includes a locking table 301 fixedly arranged coaxially with the inner cylinder 203, and the locking table 301 is prismatically arranged. A control handle 302 for facilitating the user to control the rotation of the inner cylinder 203 and the locking table 301 is fixedly arranged on one end face of the locking table 301. An outer locking member 303 is movably sleeved outside the locking table 301, and a cooperating member 304 is arranged outside the locking member 303. At the same time, the cooperating member 304 is fixedly arranged on the end face of the outer cylinder 202.

[0034] Furthermore, the locking member 303 includes a locking sleeve 303a slidably sleeved outside the locking table 301. An outer locking tooth 303b is integrally arranged at one end of the locking sleeve 303a, and a plurality of locking teeth 303b are arranged in a circular array outside the locking sleeve 303a.

[0035] The cooperating member 304 includes an outer cover 304a fixedly arranged outside the locking sleeve 303a. A locking tooth 304b is fixedly arranged on the inner wall of the outer cover 304a, and the height of the locking tooth 304b is higher than that of the locking tooth 303b.

[0036] Even further, the locking tooth 304b and the locking tooth 303b are in a snap-fit. The locking tooth 304b is deformable. Thus, when the inner cylinder 203 rotates counterclockwise, since the inclination direction of the locking tooth 304b is the same as the rotation direction of the locking tooth 303b, the locking tooth 303b can sequentially push the locking tooth 304b to deform so that it can pass smoothly. When the inner cylinder 203 stops rotating, the outermost end of the locking tooth 304b abuts against the outside of its adjacent locking tooth 303b at this time, thereby restricting the reset rotation of the inner cylinder 203 and preventing the interval between the partition rods 207 after adjustment from becoming larger again and affecting the normal guiding of the plastic-steel belt.

[0037] During use, by controlling the counterclockwise rotation of the control lever 302, the locking platform 301 and the inner cylinder 203, the distance between the partition rods 207 can be adaptively adjusted from large to small according to the width of the plastic steel belt. As the locking platform 301 rotates, the locking sleeve 303a and the locking teeth 303b rotate synchronously. Thus, under the cooperation between the locking teeth 303b and the engaging teeth 304b, the one-way rotation locking of the inner cylinder 203 is achieved, preventing the inner cylinder 203 from rotating back to its original position and causing the distance between the partition rods 207 to increase.

[0038] In summary, through the snap-fit between the locking teeth 303b and the engaging teeth 304b, the position locking of the inner cylinder 203 after rotation adjustment is achieved, ensuring the stable limiting and guiding of the plastic steel belt by the partition rods 207, and preventing the situation where the gap between the partition rods 207 increases again due to the reset rotation of the inner cylinder 203.

[0039] Example 3, referring to Figures 1 to 6 , is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a control mechanism 300 for a conveying device used in the production of plastic steel belts, which solves the problem of unlocking the locked locking platform 301.

[0040] Specifically, the locking member 303 further includes a telescopic groove 303c and a reset groove 303d provided on the outer wall of the other end of the locking sleeve 303a.

[0041] At the same time, the cooperating member 304 further includes a connecting spring 304c fixedly embedded in the inner wall of the outer cover 304a away from the engaging teeth 304b, and one end of the connecting spring 304c is fixedly connected with a push post 304d. Through the arrangement of the connecting spring 304c, the push post 304d can perform a certain telescopic movement relative to the outer cover 304a, and at the same time, the push post 304d can be slidably engaged with the telescopic groove 303c and the reset groove 303d respectively.

[0042] Preferably, the telescopic groove 303c is spirally inclined along the outside of the locking sleeve 303a, and the push post 304d is located at the outer end of the telescopic groove 303c. Thus, when the locking platform 301 rotates with the inner cylinder 203, the locking sleeve 303a can gradually extend outward under the combined action of the rotational restriction of the locking platform 301 on it and the sliding fit between the telescopic groove 303c and the push post 304d. And with the engaging teeth 304b being higher than the locking teeth 303b, during the extension process of the locking sleeve 303a, the continuous engagement between the engaging teeth 304b and the locking teeth 303b can be maintained. When the inner cylinder 203 rotates to adjust the partition rods 207 to the minimum distance, at this time, the extension distance of the locking sleeve 303a is greater than the engagement distance of the engaging teeth 304b, so the engagement between the engaging teeth 304b and the locking teeth 303b is disengaged. Thus, the locking sleeve 303a can rotate freely to achieve the purpose of resetting the inner cylinder 203 and the partition rods 207, facilitating subsequent use.

[0043] Further, the reset groove 303d is arranged in a folded groove shape, formed by a transverse groove opened circumferentially along the outer wall of the locking sleeve 303a and a vertical groove opened axially along the locking sleeve 303a, and both ends of the reset groove 303d are respectively connected to both ends of the telescopic groove 303c. The reset groove 303d and the telescopic groove 303c have different depths, and the connection between one end of the reset groove 303d and the telescopic groove 303c is sloped. Thus, when the inner cylinder 203 rotates to adjust the distance between the partition rods 207, the push column 304d can only slide inside the telescopic groove 303c to realize the gradual extension of the locking sleeve 303a. When the locking sleeve 303a is fully extended, the push column 304d relatively slides to the connection between the transverse groove of the reset groove 303d and the telescopic groove 303c. At this time, through the slope setting between the transverse groove and the telescopic groove 303c, the push column 304d can smoothly enter the transverse groove section of the reset groove 303d through its own contraction, and then the locking sleeve 303a can be rotated to reset the inner cylinder 203. After the inner cylinder 203 is reset, the push column 304d relatively moves to the vertical groove section of the reset groove 303d, and thus the locking sleeve 303a can be pushed inward to reset, so that the locking teeth 304b and the locking teeth 303b are engaged again. At the same time, under the step setting at the connection between the vertical groove section of the reset groove 303d and the telescopic groove 303c, it can be ensured that after the push column 304d returns to the telescopic groove 303c again, it will not return to the reset groove 303d again under the rotation of the locking sleeve 303a, ensuring the smooth operation of the overall function of the locking sleeve 303a.

[0044] During use, before the inner cylinder 203 is adjusted, the push column 304d is correspondingly located inside the telescopic groove 303c. Thus, through the rotation adjustment of the inner cylinder 203, the locking sleeve 303a can gradually extend under the cooperation of the push column 304d and the telescopic groove 303c. After the inner cylinder 203 completes the adjustment cycle, the push column 304d relatively moves to the connection between the transverse groove section of the reset groove 303d and the telescopic groove 303c, and with the help of the slope setting between the two, it smoothly enters the reset groove 303d. Thus, the user can first rotate the inner cylinder 203 to return it to the initial position, and then push the locking sleeve 303a inward so that the locking teeth 304b and the locking groove are engaged again. After both are reset, the push column 304d returns to the telescopic groove 303c again through the step setting at the connection between the vertical groove section of the reset groove 303d and the telescopic groove 303c, facilitating the user's reuse.

[0045] In summary, through the cooperative setting between the reset groove 303d and the telescopic groove 303c, while ensuring the normal use of the locking function of the locking member 303, the subsequent reset of the locking member 303 and the inner cylinder 203 can also be realized, ensuring the cyclic use of the guiding mechanism 200 and the control mechanism 300.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
