Description

Technical Field

[0001] The utility model relates to the field of ceramic tile manufacturing, in particular to a conveying roller control device. Background Art

[0002] Currently, ceramic tiles are at high temperatures after being fired and taken out of the kiln. Therefore, they need to pass through a cooling and conveying line that is dozens or even hundreds of meters long to gradually cool the tiles. Existing cooling and conveying lines mainly consist of several conveying units connected side by side, each controlled by a master control switch. During use, all conveying units can be started or shut down simultaneously through the master control switch. Although a master control switch allows all conveying units to be controlled simultaneously, making operation more convenient, there are also some shortcomings: because all conveying units are started or shut down simultaneously, some conveying units remain in the started and running state when no tiles are being transported. This is very wasteful of electricity and not energy-efficient, which leads to increased production costs for manufacturers. Therefore, in view of the aforementioned shortcomings of existing cooling and conveying lines, it is very necessary to further improve their structure in order to better meet people's application needs. Utility Model Content

[0003] The present utility model aims to address the aforementioned problems and deficiencies by providing a conveyor roller control device. By providing a tile sensor switch device on each conveyor unit, the device activates the corresponding conveyor roller assembly only when it senses a tile passing through, rather than activating all conveyor roller assemblies simultaneously. This avoids wasting electricity, saves energy, and reduces production costs for manufacturers. Furthermore, by providing a vertical adjustment assembly, the vertical height of the tile sensor switch device can be adjusted accordingly based on the thickness of the tile, thereby ensuring the sensing accuracy of the tile sensor switch device.

[0004] The technical solution of the present utility model is implemented as follows: a conveyor roller control device includes a plurality of conveying units connected side by side, and its characteristic is that each conveying unit includes a conveyor frame and a conveyor roller assembly arranged on the conveyor frame, and the input end of the conveyor roller assembly is provided with a vertical adjustment assembly, and the vertical adjustment assembly is provided with a tile induction switch device for controlling the start or shut down of the conveyor roller assembly.

[0005] Preferably, the conveyor roller assembly includes a plurality of conveyor rollers arranged side by side on a conveyor frame, and a clearance gap is formed between each two adjacent conveyor rollers; the tile induction switch device can vertically enter and exit the clearance gap through a vertical adjustment assembly.

[0006] Preferably, the vertical adjustment assembly includes a fixing seat with a vertical through-hole, a vertical screw inserted in the vertical through-hole, a mounting portion arranged at the lower end of the vertical screw, and two locking nuts screwed on the vertical screw, so that the vertical screw is fixed to the fixing seat by clamping the fixing seat through the two locking nuts; the fixing seat is arranged on the conveying frame, and the tile induction switch device is arranged on the mounting portion.

[0007] Preferably, the tile induction switch device includes a control switch, a light emitter and a light receiver electrically connected to the control switch, and the light emitter and the light receiver are arranged together in a linkage; the number of the vertical adjustment components is two, and the fixing seats of the two vertical adjustment components are respectively arranged on the left and right sides of the conveying frame, and the light emitter and the light receiver are respectively arranged on the corresponding mounting parts.

[0008] The beneficial effects of the present invention are as follows: By providing a tile sensor switch device on each conveying unit, the present invention activates the corresponding conveying roller assembly for conveying only when the tile sensor switch device senses a tile passing through, rather than simultaneously activating the conveying roller assemblies of all conveying units. This avoids wasting electricity, saves energy, and reduces production costs for manufacturers. Furthermore, by providing a vertical adjustment assembly, the present invention can adjust the vertical height of the tile sensor switch device. This allows the vertical height of the tile sensor switch device to be adjusted accordingly for tiles of varying thicknesses, ensuring the sensing accuracy of the tile sensor switch device, improving applicability, and making it more reliable.

[0015] like Figure 1As shown, the conveying roller control device described in the present invention includes a plurality of conveying units 1 connected side by side. In order to achieve the purpose proposed by the present invention, as shown in FIG. Figures 2 to 4 As shown, each conveying unit 1 includes a conveying frame 11 and a conveying roller assembly 12 disposed on the conveying frame 11. The input end of the conveying roller assembly 12 is provided with a vertical adjustment assembly 2, and the vertical adjustment assembly 2 is provided with a tile sensing switch device 3 that controls the start or stop of the conveying roller assembly 12. The utility model provides a tile sensing switch device 3 on each conveying unit 1. Only when a tile is sensed to be passing through will the corresponding conveying roller assembly 12 be activated for conveying. Not all conveying roller assemblies 12 are activated simultaneously, thereby avoiding waste of electrical energy, being more energy-efficient, and reducing the manufacturer's production costs. At the same time, by providing the vertical adjustment assembly 2, the vertical height of the tile sensing switch device 3 can be adjusted accordingly according to the different thicknesses of tiles to ensure the sensing accuracy of the tile sensing switch device 3.

[0016] like Figure 4 As shown, the conveyor roller assembly 12 includes a plurality of conveyor rollers 121 arranged side by side on the conveyor frame 11, with a clearance gap 122 formed between each adjacent conveyor roller 121. The tile sensor switch device 3 can vertically move in and out of the clearance gap 122 via the vertical adjustment assembly 2. By enabling the tile sensor switch device 3 to vertically move in and out of the clearance gap 122, thinner tiles can be sensed, further improving the accuracy of the sensing and the range of its application.

[0017] In order to further improve the structure of the vertical adjustment component 2, as Figure 5 and Figure 6 As shown, the vertical adjustment assembly 2 includes a fixing base 21 with a vertical through-hole 211, a vertical screw 22 inserted into the vertical through-hole 211, a mounting portion 23 disposed at the lower end of the vertical screw 22, and two locking nuts 24 threaded onto the vertical screw 22. The two locking nuts 24 clamp the fixing base 21, securing the vertical screw 22 to the fixing base 21. The fixing base 21 is mounted on the conveyor frame 11, and the tile sensor switch device 3 is mounted on the mounting portion 23. During use, the vertical position of the vertical screw 22 can be adjusted by loosening the two locking nuts 24, while the vertical screw 22 can be secured to the fixing base 21 by tightening the two locking nuts 24. The mounting portion 23 facilitates installation of the tile sensor switch device 3. In actual use, the mounting portion 23 and the tile sensor switch device 3 can be assembled together using various fixing methods, such as snap-on mounting, clip-on mounting, hanging mounting, sleeve mounting, and screw-locking. Preferably, a fitting hole is provided on the mounting portion 23, and the tile induction switch device 3 is fitted into the fitting hole of the mounting portion 23 to achieve the purpose of fitting and fixing.

[0018] In order to further improve the structure of the tile induction switch device 3, as Figure 3 and Figure 4 As shown, the tile induction switch device 3 includes a control switch 31, a light emitter 32 and a light receiver 33 electrically connected to the control switch 31, and the light emitter 32 and the light receiver 33 are arranged in conjunction with each other; the number of the vertical adjustment components 2 is two, and the fixing bases 21 of the two vertical adjustment components 2 are respectively arranged on the left and right sides of the conveyor frame 11, and the light emitter 32 and the light receiver 33 are respectively arranged on the corresponding mounting parts 23. When in use, the light emitted by the light emitter 32 directly hits the light receiver 33, forming a protective light curtain. When a tile passes by and blocks the light curtain, the light receiver 33 generates a light blocking signal and transmits it to the control switch 31, which then controls the conveyor roller assembly 12 to achieve the purpose of automatically sensing and opening the conveyor roller assembly 12. That is, the tile induction switch device 3 adopts an existing common and commonly used photoelectric protection device. Its specific connection structure and operating principle will not be elaborated here. By arranging the fixing bases 21 of the two vertical adjustment assemblies 2 on the left and right sides of the conveyor frame 11, respectively, the light emitter 32 and the light receiver 33 can also be arranged on the left and right sides of the conveyor frame 11. In this way, when in use, even if there are multiple tiles arranged in the axial direction of the conveyor roller 121, the light emitter 32 and the light receiver 33 can detect that a tile has passed. Therefore, in one conveyor unit 1, only one light emitter 32 and one light receiver 33 are required, which is very reliable. In actual application, the control switch 31 can be arranged on the conveyor frame 11 or outside the conveyor frame 11.

[0019] like Figure 3 and Figure 4 As shown, preferably, the light emitter 32 and the light receiver 33 are respectively located in the first clearance gap 122 near the input end of the conveyor roller assembly 12. This allows the input end of the conveyor roller assembly 12 to sense the tiles more quickly, and the light emitter 32 and the light receiver 33 are enclosed and less susceptible to damage from bumps and collisions. Moreover, the light emitter 32 and the light receiver 33 do not affect the rotation and conveying action of the conveyor roller 121, thereby achieving high reliability.

[0020] In practical applications, in order to speed up the cooling effect of the tiles, the conveyor frame 11 is further provided with a fan 4 located above the conveyor roller assembly 12. When in use, the tiles conveyed on the conveyor roller assembly 12 can be air-cooled to speed up the cooling of the tiles.

[0021] In actual application, each conveying roller 121 is driven by a motor to perform a rotational conveying action. When all the conveying rollers 121 in a conveying roller assembly 12 are driven by only one motor, each two adjacent conveying rollers 121 are also connected to a transmission belt. In this way, multiple conveying rollers 121 can be driven by one motor to perform a rotational conveying action at the same time. Its specific structure and operating principle can also be referred to the patent document with Chinese patent application number 202420480757.4, entitled "A Construction Material Lifting Device". This solution records the specific structure and operating principle of driving multiple conveying rollers by one motor, which will not be elaborated here.
