Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and in particular relates to a novel conveying device used for curing, maintaining and forming artificial stones. Background Art

[0002] Taking terrazzo, an artificial stone, as an example, during the processing, the pressed and formed panels need to enter multiple heating compartments in the curing and maintenance equipment for curing and forming.

[0003] At present, when the pressed and formed sheet is conveyed on the bottom template, it is necessary to set a cylinder on the discharge side of the curing equipment, and use the driving end of the cylinder to extend into the curing equipment and extend from the other end to pull the bottom template, so that the bottom template can be pulled into the curing equipment by the cylinder. After heating and forming, the cylinder extends again to pull the bottom template out.

[0004] This method requires a larger cylinder and a longer telescopic distance. In addition, the operation of the cylinder is not precise, so it needs to be used with more photoelectric detection and limit components. The structure is too complicated and easy to damage, affecting normal production. In addition, the cylinder's telescopic stroke is not accurate, and sometimes the telescopic distance is not enough to grab the bottom template. If the telescopic distance is too long, it will touch the material on the bottom template, which will eventually affect product quality and efficiency, and the defective rate is also at a high ratio.

[0005] The Chinese utility model patent with application number 2024201268562 discloses a conveying device for a terrazzo forming machine. The bottom template is placed on a feeding plate, and the feeding plate and the bottom template are fed into the curing device together. When the feeding plate is extended to the other end of the heating interlayer in the curing setting, the one-way lever on the interlayer will hook the paddle at the end of the bottom template to achieve the limit fixation of the bottom template, and then the feeding plate can return to reset. That is, the feeding plate needs to be fully extended into the interlayer to the other end of the interlayer, while the bottom template does not move to achieve the relative separation of the two. This structure does not require the coordination of numerous monitoring components and has a simpler structure.

[0006] However, this method requires the feed plate to be fully extended into the heating interlayer in the curing equipment. The extension stroke is fixed and cannot be extended to any distance. In addition, the bottom surface of the feed plate will fit with the top surface of the heating base plate on the interlayer to form a contact-type hard friction connection. After a period of use, the top surface of the heating base plate will be worn to a certain extent, and the flatness will be greatly affected, which will cause defects on the surface of the artificial stone plate after curing. In addition, if the heating base plate is seriously damaged, it needs to be stopped for replacement. There are many interlayers in the curing equipment, and there are many parallel heating base plates in the interlayers. Stopping for replacement is not only time-consuming and labor-intensive, but also causes great losses.

[0007] Secondly, the feed plate in the above patent application is horizontally extended into the interlayer as a whole, that is, when the bottom template first enters the feed plate, the two cannot achieve relative movement, and a moving frame must be set above the feed plate to pull the bottom template completely into the feed plate. This structure will cause the bottom template to go through an additional process before it can be completely placed on the feed plate, occupying the limited time in assembly line production, and the subsequent bottom template needs to wait in line on the conveyor belt, which restricts work efficiency.

[0008] Therefore, it is necessary to make further upgrades and renovations on the original basis to realize the arbitrary adjustment of the bottom template feeding stroke, and it will not cause wear on the surface of the heating bottom plate in the interlayer, improve product quality, and reduce the operation process and improve work efficiency. Utility Model Content

[0009] The utility model aims to solve the technical problems in the prior art that the bottom template extension distance cannot be adjusted, easy wear affects the quality of the plate and the work efficiency is low, and to provide a new type of conveying device to overcome the shortcomings of the prior art.

[0010] The technical solution adopted by the utility model is: a new type of conveying device, which is characterized by: comprising:

[0011] A conveying component, which is used for conveying the bottom template;

[0012] A pushing rack is arranged above the conveying component at intervals. A pushing structure is provided on the forward end of the pushing rack. The pushing structure is correspondingly connected to the pushing seat at the forward end of the bottom template. The pushing rack performs reciprocating stroke motion along the conveying direction of the conveying component through a driving mechanism, thereby realizing the conveying of the bottom template.

[0013] As a further improvement, the pushing structure includes a supporting portion fixedly connected to the forward end of the pushing frame, the forward end of the supporting portion is hinged with a one-way tooth portion corresponding to the pushing seat, and the one-way tooth portion rotates toward the forward end with the hinge point as the center of the circle.

[0014] As a further improvement, the driving mechanism includes a driving shaft and a driven shaft, one end of the driving shaft is connected to the driving member, the two ends of the driving shaft and the two ends of the driven shaft are synchronously driven by chains, and the chain is fastened to the two side edges of the pushing frame in the direction of travel through fasteners.

[0015] As a further improvement, the fastener includes a screw rod connected to both ends of the chain, and the screw rod is fastened to the positioning plates provided on the pushing frame through nuts.

[0016] As a further improvement, pulleys slidably connected to the two sides of the conveying component are provided at both sides of the bottom of the pushing frame.

[0017] As a further improvement, the conveying component is a belt conveyor.

[0018] As a further improvement, the driving member is a driving motor.

[0019] After adopting the above technical solution, the technical effects of the utility model are:

[0020] The bottom template does not need to be placed on the feeding plate, nor does it need to be transported by the feeding plate, so there will be no hard contact friction connection between the feeding plate and the interlayer surface. In addition, the bottom template is made of soft rubber material, which will not cause wear on the interlayer surface. The surface of the formed plate is flawless and the quality is guaranteed.

[0021] The push rack and the conveying component are set at intervals. The push rack is extended between each two adjacent compartments through the driving motor, and the pulley and the surface of the compartment are connected by rolling, which will not cause wear. The travel distance of the push rack is controlled by the driving motor, and the extension distance can be adjusted as needed to meet the needs of forming plates of different specifications. It does not require manual operation and is easier to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined Figures 1 to 13 The technical solution of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0043] Reference Figures 1 to 13 The utility model is a new type of conveying device, which can realize arbitrary adjustment of the pushing distance, can adapt to the pressing needs of plates of different specifications, and has no friction with the interlayer surface in the forming machine, thus ensuring the quality of the artificial stone plate and reducing the defective rate. Specifically, it includes a conveying component 100, which is used for conveying the bottom template 500, such as Fig.12 and Fig.13As shown, the conveying component 100 is a commonly used belt conveyor, and its front end corresponds horizontally to the inlet end of the partition in the forming machine, so as to facilitate the pushing in of the bottom template.

[0044] The push rack 200 is also included, which is arranged above the conveying component 100, that is, a gap 202 is left between the conveying component 100 and the push rack 200 in the height direction, and this gap is used to place the plate 6 and the bottom template 500. The plate 6 is placed on the bottom template 500, and when the bottom template 500 is transported by the belt conveyor, it can move unobstructed in the gap 202 (such as Fig.13 As shown). Compared with the original equipment, the structure here omits the feeding plate and moving parts, and the bottom membrane plate 500 itself is a soft rubber material, which will not cause wear on the surface of the interlayer, and the quality of the pressed artificial stone plate can be guaranteed and unified.

[0045] A pushing structure 201 is provided on the forward end (i.e., the forward direction of pushing) of the pushing rack 200. The pushing structure 201 includes a support portion 2011 fixedly connected to the forward end of the pushing rack 200. The forward end of the support portion 2011 is hinged with a one-way toothed portion 2012 corresponding to the pushing seat 501. The one-way toothed portion 2012 rotates toward the forward end with the hinge point 2013 as the center. In other words, the one-way toothed portion 2012 can rotate unidirectionally with the hinge point 2013 as the center. Here, the one-way means rotating toward the forward direction of pushing, and cannot rotate toward the backward direction because the rear position is blocked by the support portion 2011 and cannot rotate. The reinforcing ribs 2014 play a role of stable support to prevent the support portion 2011 from deforming.

[0046] refer to Fig.13 When the bottom template 500 is conveyed by the belt conveyor, the push seat 501 at the front end will contact the one-way tooth-shifting part 2012 and rotate around the hinge point 2013 and finally be located behind the push seat 501. Fig.11 The push frame 200 is arranged at both sides of the bottom of the push frame 200, and is slidably connected to both sides of the conveying member 100. The push frame 200 will not be disturbed by the bottom template 500 and the conveyor belt when moving, and can move smoothly. When the push frame 200 extends into the interlayer, the pulley 203 can also protect the surface of the heating bottom plate from being worn.

[0047] The reason why pulleys are used instead of linear guides is that pulleys not only play the role of sliding connection to prevent wear, but also play a supporting role for the push rack 200 when the push rack 200 enters the compartment, preventing the push rack from bending and deforming due to lack of support. Linear guides are not applicable because they cannot extend into the compartment to play an effective supporting and limiting role.

[0048] refer to Fig.12 When the one-way toothed portion 2012 is connected to the push seat 501 at the forward end of the bottom template 500, the push rack 200 can perform reciprocating stroke motion in the conveying direction of the conveying component 100 through the driving mechanism, thereby conveying the bottom template 500 into the interlayer. Since the push rack 200 is powered by a driving motor, the pushing stroke (i.e., the pushing distance) can be precisely controlled without the use of auxiliary photoelectric and other detection equipment, and can achieve pushing at any position, fully adapting to the pressing needs of plates of different specifications, ensuring that the bottom mold is pushed to the center of the interlayer, and the pressing is more balanced. Compared with the original equipment, this structure omits the one-way lever at the outlet end of the interlayer, that is, the bottom template 500 does not need to be completely pushed to the outlet end position of the interlayer, and the pushing distance can be arbitrarily changed according to needs.

[0049] In addition, compared with the original structure, moving parts are omitted, saving additional process flow. Specifically, the traditional feeding plate is replaced by a belt conveyor, and the bottom template 500 can be directly transported to the predetermined station without the need for additional moving parts to transport it into place. When the first bottom template 500 is pushed into the interlayer by the push rack 200, the second bottom template 500 can directly enter the belt conveyor for transportation, as long as the speed of the belt conveyor is lower than the travel speed of the push rack 200 and there is no interference with each other, thereby adapting to the assembly line production line.

[0050] As a further improvement of this embodiment, the driving mechanism includes a driving shaft 302 and a driven shaft 303, which are arranged in the width direction of the conveying component 100 and parallel to each other. One end of the driving shaft 302 is connected to the driving member 301 (i.e., the driving motor), and the two ends of the driving shaft 302 and the two ends of the driven shaft 303 are synchronously driven with each other through chains 304. The chain 304 is fastened to the two side edges of the pushing frame 200 in the moving direction through fasteners.

[0051] The reason why two chains 304 are used is that they can provide stable transportation without deviation. Specifically, when the push rack 200 performs reciprocating linear push motion, it is necessary to ensure that the linear direction does not deviate, especially in the process of extending into the interlayer, because there is no place in the interlayer that can limit the push rack 200, and the linear motion of the push rack 200 is achieved only by the synchronous transmission of the two chains 304. If one chain 304 is used, it is easy for the push rack 200 to deviate from the direction of travel, and the bottom template 500 will enter the interlayer in a skewed state, so that the pressed bottom template 500 cannot be adapted and hooked with the one-way lever on the removal component, thereby causing the situation of unhooking and falling. Of course, the two chains 304 can also be replaced by belts that can produce the same transmission effect. The driven shaft 303 or the drive shaft 302 can also be replaced by two driven wheels, as long as the synchronous transmission of the two chains 304 can be achieved.

[0052] The working principle is:

[0053] After the plate 6 on the bottom template 500 is pressed and formed, it will be directly transported to the bottom of the push frame 200 along the belt conveyor 100, saving the traditional additional transportation process of moving parts. As the bottom template 500 is gradually transported, the push seat 501 at its front end will contact the one-way tooth part 2012 and rotate around the hinge point 2013 until the one-way tooth part 2012 is located behind the push seat 501 (such as Fig.12 As shown). At this time, the belt conveyor stops running, and the push frame pushes the push seat 501, thereby moving the bottom template 500 forward as a whole. The entry distance of the bottom template 500 is controlled by the driving motor, and the extension distance can be arbitrarily controlled. After reaching the predetermined position, the driving motor reverses to return the push frame 200 to its original position, waiting for the next bottom template 500 to enter. When the push frame 200 moves in the stroke, the belt conveyor 100 can also be provided with a corresponding limit track to improve the straightness of its stroke movement, improve the accuracy of the linear movement, and prevent deviation.

[0054] The push structure 201 can be set to multiple (such as Figure 2 ), and are evenly arranged with each other to achieve linear and stable transportation of the bottom template 500. Example

[0055] refer to Fig.10 In this embodiment, the purpose is to realize the calibration adjustment of the pushing frame 200. The fasteners include a screw rod 402 connected to both ends of the chain 304, that is, the two ends of the chain 304 where the chain 304 is disconnected are respectively fixed with screw rods 402, and the screw rods 402 are respectively fastened to the positioning plates 401 provided on the pushing frame 200 through nuts 403.

[0056] When the screw rod 402 on one side of the pushing rack 200 is tightened, the other side thereof will be offset, that is, the axial angle of the pushing rack 200 will change accordingly, thereby achieving fine-tuning of the pushing direction of the pushing rack 200. The positioning plate 401 is arranged at the end position of the pushing rack 200, so that the pushing rack 200 can be ensured to extend into the partition. The above structure is arranged at the rear end of the pushing rack 200, which is equivalent to being located at the rear end of the belt conveyor, so that the pushing rack 200 can fully extend into the space in the partition, and does not hinder the mutual restraint between the pushing rack 200 and the chain 304. That is, after the pushing rack 200 extends into the partition, the positioning plate 401 is located at the front end position of the belt conveyor (refer to Figure 2 ).

[0057] The utility model can be arranged at the feeding end and / or the sending end of the curing device, both for achieving the pushing effect of feeding in or sending out the bottom template 500.

[0058] For example, when the utility model is arranged at the delivery end of the curing device, it is used to pull out (i.e., deliver) the cured bottom template 500. The push structure 201 on the push frame 200 is also arranged in the direction of the bottom template 500, and the hinged one-way tooth-pulling portion 2012 is also rotated in the direction of the travel of the bottom template 500. In the other direction, the one-way tooth-pulling portion 2012 can be blocked by a blocking portion (such as adding a gear lever or other components), thereby realizing its one-way rotation. When the push mechanism 201 gradually approaches the bottom template 500, the one-way tooth-pulling portion 2012 is blocked by the push seat and rotates with the hinge point as the center of the circle. Then, the push frame 200 pulls out the bottom template 500, and this process is consistent with the principle of the delivery end, except that the direction in which the one-way tooth-pulling portion 2012 rotates is as long as it rotates in the direction of the travel of the bottom template 500.

[0059] After adopting the above technical solution, the technical effects of the utility model are:

[0060] The bottom template does not need to be placed on the feeding plate, nor does it need to be transported by the feeding plate, so there will be no hard contact friction connection between the feeding plate and the interlayer surface. In addition, the bottom template is made of soft rubber material, which will not cause wear on the interlayer surface. The surface of the formed plate is flawless and the quality is guaranteed.

[0061] The push rack and the conveying component are set at intervals. The push rack is extended between each two adjacent compartments through the driving motor, and the pulley and the surface of the compartment are connected by rolling, which will not cause wear. The travel distance of the push rack is controlled by the driving motor, and the extension distance can be adjusted as needed to meet the needs of forming plates of different specifications. It does not require manual operation and is easier to use. Compared with the traditional method that can only be sent to a fixed position, more plates of different specifications can be used.

[0062] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
