[0001] This invention relates to the field of ceramic tile manufacturing equipment technology, and specifically to a material feeding device for thin ceramic tiles. Background Technology

[0002] In the ceramic tile manufacturing process, a material feeding device is often used to distribute one or more layers of ceramic particles / powder onto the molds / blanks on the conveyor line, such as... Figure 1 The diagram shown is a schematic of an adjustable feeding hopper in the prior art. However, existing adjustable feeding hoppers still have problems such as poor accuracy in adjusting the discharge port width, difficulty in manufacturing, and the need for further improvement in adjustment effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a material feeding device for thin bricks, which can achieve fine adjustment of the width of the discharge port of the feeding hopper, and has a simple structure, is easy to manufacture, has good adjustment effect, and is low in cost.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A feeding device for thin bricks includes a feeding hopper (1) and an adjusting component (2). The feeding hopper is generally elongated and includes a first sidewall and a second sidewall arranged opposite each other. The first sidewall includes a first vertical section (11) and a first inclined section (12) connected together. The second sidewall includes a second vertical section (13) and a second inclined section (14) connected together. The bottom of the first inclined section and the second inclined section form a discharge port (15). An adjusting component is provided on one side of the first sidewall. The adjusting component (2) includes a mounting block (21), a first screw (22), a second screw (23), and a transmission arm (16). The mounting block is fixedly installed on one side of the first vertical section, and a threaded hole is provided in the mounting block. The first screw is threadedly connected to the threaded hole. The first screw includes a first head and a first rod. The first rod includes a first external thread (24) and a first internal thread (25). The second screw is threadedly connected to the first internal thread. A bend (Q) is formed at the connection between the first vertical section and the first inclined section. A transmission arm is connected to the outside of the bend. The upper end of the transmission arm abuts against the bottom of the second screw. The first sidewall is at least partially made of a material that can be elastically deformed, so that when the second screw moves vertically under the drive of the first screw, the first inclined section (12) bends or rotates about the bend (Q) through the transmission arm, thereby adjusting the discharge flow rate or discharge width of the discharge port of the cloth hopper.

[0006] Furthermore, the second screw (23) includes a second head and a second rod portion. The second rod portion includes a second external thread (26), which is threadedly engaged with the first internal thread (25). The pitch of the first external thread (24) is greater than the pitch of the second external thread.

[0007] Furthermore, the first head of the first screw (22) has an outer polygonal structure and / or an inner polygonal structure to facilitate the use of a torque tool to transmit torque; the threaded hole in the mounting block (21) is a through hole, and the first vertical section (11), the first inclined section (12), and the transmission arm (16) are integrally formed.

[0008] Furthermore, the second screw (23) is also provided with a through hole (27), which axially penetrates the second screw (23). The through hole includes a two-stage stepped hole, with the large-diameter hole opened in the second rod part of the second screw and the small-diameter hole opened in the second head. A connector (28) is installed in the through hole, and a nut (29) is connected to the lower end of the connector.

[0009] Furthermore, the connector (28) includes a third head and a third rod. The third head is a limiting part. The outer circumferential surface of the third rod includes a smooth shaft section and a threaded section. The threaded section is only provided at the lower end of the third rod. The nut (29) is installed on the connector (28) through the threaded section.

[0010] A method for adjusting a material feeding device for thin bricks, comprising the following steps:

[0011] Step (1): The first screw (22) is rotated by a torque tool or by hand. The first screw moves vertically. The first screw drives the second screw (23) to rotate and move vertically through the first internal thread (25). Since the second screw and the connector (28) can rotate relative to each other, the second head of the second screw abuts against the transmission arm (16). Since the first sidewall is at least partially made of elastically deformable material, the first inclined section (12) bends / rotates about the bending part (Q) in the first direction, thereby adjusting the discharge flow rate or discharge width of the discharge port (15) of the cloth hopper to achieve fine adjustment of the discharge port width.

[0012] Step (2): The first screw (22) is rotated in the opposite direction by a torque tool or by hand. The first screw moves vertically. The first screw drives the second screw (23) to rotate and move vertically through the first internal thread (25). Since the second screw and the connector (28) can rotate relative to each other, the second head of the second screw abuts against the transmission arm (16). Since the first sidewall is at least partially made of elastically deformable material, the first inclined section (12) bends / rotates about the bending part (Q) in the second direction. The second direction is opposite to the first direction, so that the discharge flow rate or discharge width of the discharge port (15) of the cloth hopper can be adjusted to achieve fine adjustment of the discharge port width.

[0013] The present invention provides a material feeding device for thin bricks, which can achieve fine adjustment of the width of the discharge port of the material feeding hopper, and has a simple structure, is easy to manufacture, has good adjustment effect, and is low in cost.

[0018] To make the technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in a clearer and more complete manner below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of the present invention, and are only used to explain the present invention, not to limit the present invention. It should be noted that, for ease of description, only the parts / structures related to the present invention are shown in the accompanying drawings. Other related parts can be referred to with ordinary design. In the absence of conflict, the embodiments and technical features in the embodiments of the present invention can be combined with each other to obtain new embodiments.

[0019] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this invention. Furthermore, unless otherwise defined, the technical or scientific terms used in the description of this invention should have the ordinary meaning understood by those skilled in the art.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] like Figure 2-3 As shown, a material feeding device for thin bricks includes a feeding hopper 1 and an adjusting assembly 2. The feeding hopper 1 is generally elongated and includes a first sidewall and a second sidewall arranged opposite each other. The first sidewall includes a first vertical section 11 and a first inclined section 12 connected together. The second sidewall includes a second vertical section 13 and a second inclined section 14 connected together. The bottom of the first inclined section 12 and the second inclined section 14 forms a discharge port 15. An adjusting assembly 2 is provided on one side of the first sidewall. The adjusting assembly 2 is characterized in that: the adjusting assembly 2 includes a mounting block 21, a first screw 22, a second screw 23, and a transmission arm / plate 16. The mounting block 21 is fixedly installed on one side of the first vertical section 11. A threaded hole is opened in the mounting block 21, and the first screw 22 is threadedly connected to the threaded hole. The first screw 22 includes a first head and a first... The rod portion includes a first external thread 24 and a first internal thread 25. The second screw 23 is threadedly connected to the first internal thread 25. A bend / pivot portion Q is formed at the connection between the first vertical section 11 and the first inclined section 12 (the bend / pivot portion Q is a general or main bend). A transmission arm / plate 16 is connected to the outside of the bend portion Q. The upper end of the transmission arm 16 abuts against the bottom of the second screw 23. The first sidewall is at least partially made of an elastically deformable material so that when the second screw 23 moves vertically under the drive of the first screw 22, the transmission arm 16 causes the first inclined section 12 to bend / rotate about the bend portion Q, thereby adjusting the discharge flow rate of particles / powder at the discharge port 15 of the hopper 1 (i.e., adjusting the width / horizontal dimension of the discharge port 15).

[0022] The second screw 23 includes a second head and a second rod portion. The second rod portion includes a second external thread 26, which is screwed into the first internal thread 25. The pitch of the first external thread 24 is greater than the pitch of the second external thread 26. That is, the distance that the first screw 22 moves vertically in one revolution is greater than the distance that the driven second screw 23 moves vertically in one revolution, so as to achieve fine adjustment.

[0023] The pitch of the first external thread 24 and the pitch of the second external thread 26, as well as the bending / rotation angle that the first inclined section 12 can generate, can be determined according to the design and the width adjustment requirements of the discharge port 15.

[0024] The first sidewall is at least partially made of an elastically deformable material, such as the transmission plate 16, the first inclined section 12 and / or the first vertical section 11 being made of an elastically deformable material.

[0025] The first head of the first screw 22 has an outer polygonal structure and / or an inner polygonal structure to facilitate torque transmission by using a torque tool.

[0026] The threaded hole inside the mounting block 21 is a through hole, and the first vertical section 11, the first inclined section 12, and the transmission arm 16 are integrally formed.

[0027] like Figure 3 As shown, in one embodiment, the second screw 23 is also provided with a through hole 27, which axially penetrates the second screw 23. The through hole 27 includes a two-stage stepped hole, with the larger diameter hole opened in the second rod portion of the second screw 23 and the smaller diameter hole opened in the second head portion. A connector 28 is installed in the through hole 27, and a nut 29 is connected to the lower end of the connector 28.

[0028] The connector 28 includes a third head and a third rod. The third head is a limiting part. The outer circumferential surface of the third rod includes a smooth shaft section and a threaded section. The threaded section is only provided at the lower end of the third rod. The nut 29 is installed on the connector 28 through the threaded section. The third head and the nut 29 mainly serve to limit and drive the transmission arm 16 to bend.

[0029] The present invention provides a material feeding device for thin bricks, the working principle / adjustment process of which is as follows:

[0030] (1) The first screw 22 is rotated by a torque tool or by hand. The first screw 22 moves vertically. The first screw 22 drives the second screw 23 to rotate and move vertically through the first internal thread 25. Since the second screw 23 and the connecting member 28 can rotate relative to each other, the second head of the second screw 23 abuts against the transmission arm 16. Since the first sidewall is at least partially made of elastically deformable material, the first inclined section 12 bends / rotates about the bending part Q (the bending part / pivoting part Q is the general or main bending part) in the first direction, thereby adjusting the discharge flow rate of the particles / powder of the discharge port 15 of the feeding hopper 1 (i.e., adjusting the width / horizontal dimension of the discharge port 15) to achieve fine adjustment of the width of the discharge port 15.

[0031] (2) The first screw 22 is rotated in the opposite direction by a torque tool or by hand. The first screw 22 moves vertically. The first screw 22 drives the second screw 23 to rotate and move vertically through the first internal thread 25. Since the second screw 23 and the connecting member 28 can rotate relative to each other, the second head of the second screw 23 abuts against the transmission arm 16. Since the first sidewall is at least partially made of elastically deformable material, the first inclined section 12 bends / rotates about the bending part Q in the second direction. The second direction is opposite to the first direction, so that the discharge flow rate of the particles / powder of the discharge port 15 of the feeding hopper 1 can be adjusted (i.e., the width / horizontal dimension of the discharge port 15 is adjusted) to achieve fine adjustment of the width of the discharge port 15.

[0032] The present invention provides a material feeding device for thin bricks, which can achieve fine adjustment of the width of the discharge port 15 of the material feeding hopper 1, and has a simple structure, is easy to manufacture, has good adjustment effect, and is low in cost.

[0033] The above embodiments are illustrative of the present invention and not intended to limit the invention. It is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
