Description

Technical Field

[0001] This utility model relates to a support frame for drying veneer and a veneer drying production line having the same, belonging to the technical field of veneer drying equipment. Background Technology

[0002] With the continuous expansion of the wood products industry market and the rapid growth in demand for high-end home furnishing products, the quality requirements for veneer materials, as core raw materials for furniture manufacturing and decorative substrates, have significantly increased in industrial production. Traditional veneer drying processes mostly employ manual open-air sun-drying. Workers are required to participate in the entire process of veneer handling, spreading, and turning, ultimately relying on natural ventilation and sunlight for drying. This model has significant drawbacks: 1. Open-air sun-drying makes veneer highly susceptible to weather conditions; the temperature and humidity of the environment during drying vary with the weather and time, resulting in inconsistent veneer quality and increasing production costs for enterprises; 2. Manual spreading makes it difficult to ensure uniform heating of veneers, leading to large fluctuations in veneer moisture content, directly affecting the quality of the finished plywood; 3. Low veneer drying efficiency and low manual handling efficiency. Especially in the production of high-end decorative veneers, the traditional manual open-air sun-drying process results in a high rate of veneer warping and deformation, severely restricting product quality stability.

[0003] Traditional sun-drying methods have significant drawbacks, making it necessary to develop mechanized veneer drying production lines. A key challenge for these lines is maximizing the amount of veneer that can be placed within a limited space. The support frame for securing the veneers is a crucial component, therefore, a well-designed and structurally sound support frame system is essential for successful veneer drying production.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0030] Example 1: As Figures 1-3 As shown, according to a first aspect of the present invention, a support frame 25 for drying veneer is provided, comprising:

[0031] A support body 1 is arranged along a first direction, and connecting pieces 4 are provided at both ends of the support body 1;

[0032] Multiple rods 2, each extending along a second direction and spaced apart, have one end connected to the support body 1, and the other end of each rod 2 is a free end; the second direction is perpendicular to the first direction;

[0033] Hanging bracket 3, two hanging brackets 3 form a group, and two hanging brackets 3 in the same group are installed opposite each other on a pole 2 at a preset interval. The single board is placed by cooperating with multiple groups of hanging brackets 3 installed in the same way and the pole 2.

[0034] Furthermore, the hanger 3 includes a connecting portion 3-1 connected to the rod 2, and the connecting portion 3-1 is provided with an extension portion extending along a third direction, and the end of the extension portion is provided with a limiting portion 3-2 extending along a second direction; when the two hangers 3 are installed opposite each other, the limiting portion 3-2 of the first hanger 3 is located on the side of the extension portion of the first hanger 3 closer to the second hanger 3, and the limiting portion 3-2 of the second hanger 3 is located on the side of the extension portion of the second hanger 3 closer to the first hanger 3; the third direction is perpendicular to both the second direction and the first direction.

[0035] Furthermore, the support body 1 is formed by welding double-layered stacked square steel; the rod body 2 is made of round steel; one end of the rod body 2 is fixed to the support body 1 by welding or other means; the connecting part 3-1 is provided with a connecting hole for the rod body 2 to pass through, and the connecting hole and the rod body 2 can be fixed by welding or other means or can be an integral structure.

[0036] Furthermore, the veneer includes, but is not limited to, eucalyptus veneer.

[0037] like Figure 1-10 As shown, according to a second aspect of the present invention, a veneer drying production line is provided, including a veneer drying support frame 25 and a frame 24 installed in a drying workshop. The frame 24 is provided with a power drive component and a chain drive assembly. The chain drive assembly includes a main chain 5. The veneer drying support frame is connected to the chain drive assembly through a connecting piece 4. The power drive component drives the veneer drying support frame to circulate with the main chain 5 in the chain drive assembly, so that the heat source input into the drying workshop dries the veneer.

[0038] Furthermore, such as Figure 3 As shown, the connecting piece 4 is provided with two symmetrical ear plates on the side connected to the chain drive assembly. The two ear plates are ear plate I4-1 located at one end of one side of the connecting piece 4 and ear plate II4-2 located at the other end of one side.

[0039] Furthermore, such as Figure 10As shown, the veneer drying support frame is in multiple sets. For any veneer drying support frame A, the ear plate I4-1 of the connecting piece 4 of the veneer drying support frame A and the ear plate II4-2 of the connecting piece 4 of the first adjacent veneer drying support frame A are installed at the same link of the main chain 5 in the chain drive assembly by a pin. The ear plate II4-2 of the connecting piece 4 of the veneer drying support frame A and the ear plate I4-1 of the connecting piece 4 of the second adjacent veneer drying support frame A are installed at the same link of the main chain 5 in the chain drive assembly by a pin. The first adjacent veneer drying support frame is located on one side of the ear plate I4-1 of the connecting piece 4 of the veneer drying support frame A, and the second adjacent veneer drying support frame is located on one side of the ear plate II4-2 of the connecting piece 4 of the veneer drying support frame A. By using the connecting pieces described above and in conjunction with the assembly method described above, compared with the sequential assembly method, the installation density of the support frame for drying the single board is increased within a unit space.

[0040] Furthermore, the single-board drying production line also includes a guide assembly for guiding the movement of the main chain 5.

[0041] Furthermore, such as Figure 6 , Figure 8 , Figure 9 As shown, the guide assembly includes an upper guide rail base 16, an upper guide rail 17, a lower guide rail base 18, and a lower guide rail 19. The upper guide rail base 16 and the lower guide rail base 18 are arranged in an alternating manner on the frame 24. The upper guide rail 17 is installed on the upper guide rail base 16, and the lower guide rail 19 is installed on the lower guide rail base 18. The upper guide rail 17 cooperates with the inner chain of the main chain 5, and the lower guide rail 19 cooperates with the outer chain of the main chain 5.

[0042] Furthermore, the lower guide rail 19 is provided with an L-shaped bracket 20 arranged at intervals from the lower guide rail 19 on the side near the center of the frame 24.

[0043] As can be seen from the above technical solution, the veneer drying production line of this utility model is placed in a drying workshop, which is covered with insulation board and has an inlet and an outlet. The drying workshop can effectively utilize the heat source medium, and through the guiding effect of the guiding component, the main chain 5 can stably transport the flat veneers placed on the veneer drying support frame, thereby making eucalyptus and other veneers evenly heated and improving the drying quality. At the same time, based on the assembly method of the veneer drying support frame, the loading capacity of the entire veneer drying production line is increased, and the entire production line is compactly designed and adaptable to various production environments. It can be adapted to large-scale automated production lines and can also be flexibly applied to small and medium-sized processing sites.

[0044] Specifically:

[0045] The rack 24 is divided into a front rack, a middle rack, and a rear rack connected in sequence.

[0046] The power drive component includes a power support frame 6, a coupling 7, a first transmission shaft 8, a drive component, a second transmission shaft 15, and a third transmission shaft 22. The drive component includes a three-phase asynchronous motor 12 and a reducer 13 connected to the three-phase asynchronous motor 12.

[0047] The chain drive assembly includes a first bearing seat 9, a first sprocket 10, a second sprocket 11, a second bearing seat 14, a main chain 5, an auxiliary chain, a third bearing seat 21, and a third sprocket 23.

[0048] The following description focuses on the construction of the front frame, middle frame, and rear frame, as well as the components of the power drive unit, chain drive assembly, and guide assembly installed on each frame:

[0049] like Figure 5 As shown, the front-end frame is constructed by welding multiple square steel bars. A power support frame 6 is installed on the side of the front-end frame near the middle frame. A drive component is installed on one side of the power support frame 6, and the other side of the power support frame 6 is connected to one end of a first drive shaft 8 via a coupling 7. Three first bearing seats 9 are installed on the front-end frame, and first bearings are installed inside the first bearing seats 9. The first drive shaft 8 mates with the first bearings, and a set of first sprockets 10 is installed at each end of the first drive shaft 8. A second sprocket 11 is installed on the first drive shaft 8 between the two sets of first sprockets 10. The power provided by the three-phase asynchronous motor 12 in the drive component is transmitted to the first drive shaft 8 via a reducer 13 and a coupling 7. A second bearing seat 14 is installed on the side of the front-end frame away from the middle frame, and a second bearing is installed inside the second bearing seat 14. A second drive shaft 15 mates with the second bearing, and a set of first sprockets 10 is installed at each end of the second drive shaft 15. A second sprocket 11 is installed on the second drive shaft 15 between the two sets of first sprockets 10. Furthermore, the first sprocket 10 is a double sprocket, which is used to connect the main chain 5. The main chain 5 is a double-row chain, including an inner chain and an outer chain. The second sprocket 11 is a single sprocket. The second sprocket 11 on the first drive shaft 8 and the second sprocket 11 on the second drive shaft 15 are connected by an auxiliary chain. The auxiliary chain is a single-row chain.

[0050] like Figures 6-8As shown, the central frame is constructed by welding multiple square steel bars. The central frame has upper guide rails 17 installed on both sides along the conveying direction via upper guide rail base 16 and lower guide rails 19 installed via lower guide rail base 18. The lower guide rail 19 has L-shaped brackets 20 arranged at intervals on the side near the center of the central frame. The interval design avoids interference with the single-board drying support frame when the main chain 5 runs to the lower layer.

[0051] like Figure 9 As shown, the rear frame is constructed by welding multiple square steel bars. A third bearing seat 21 is installed on the side of the rear frame away from the front frame, and a third bearing is installed inside the third bearing seat 21. The third drive shaft 22 cooperates with the third bearing, and a set of third sprockets 23 are installed at each end of the third drive shaft 22. Further, the third sprockets 23 are double sprockets, and the third sprockets 23 and the first sprockets 10 are meshed and connected to the main chain 5. The lower guide rail base 18 and the corresponding lower guide rail 19 of the middle frame extend to both sides of the rear end frame along the conveying direction. The portion of the lower guide rail 19 extending to the rear frame has L-shaped brackets 20 arranged at intervals on the side near the center of the rear frame. In specific applications, considering that the third sprockets on the rear frame can guide the direction of movement, only the lower guide rail base 18 and the corresponding lower guide rail 19 are extended, while the upper guide rail base and upper guide rail 17 do not extend to the rear frame.

[0052] refer to Figure 8 The upper guide rail 17 is closer to the center of the frame than the lower guide rail 19. Based on this design, the upper guide rail 17 is embedded and cooperates with the inner chain of the main chain 5, and the lower guide rail 19 is embedded and cooperates with the outer chain of the main chain 5. It further cooperates with the guide rail base and the L-shaped bracket to support the main chain 5, making the movement trajectory of the main chain 5 more stable. That is, the upper guide rail base 16, the upper guide rail 17 and the frame mainly provide guidance and support for the operation of the main chain 5 in the upper layer, while the lower guide rail base 18, the lower guide rail 19 and the L-shaped bracket 20 jointly provide guidance and support for the operation of the main chain 5 in the lower layer.

[0053] It should be noted that, in addition to the connecting plates used in the single-board drying support frame, connecting plates can also be used for the horizontal sides of the L-shaped support; the bottom of the lower guide rail base 18 can also be welded to the connecting plates welded and fixed to the frame to achieve support. By using connecting plates in different positions, it is not necessary to obtain different connecting parts during processing / procurement, which greatly reduces the complexity of processing / procurement.

[0054] In the above description, the front-end frame, middle frame, and rear-end frame can be constructed using square steel of varying lengths, connected by welding or other methods. The length direction of the frame is parallel to the conveying direction of the main chain and auxiliary chain.

[0055] The working principle of this utility model is as follows:

[0056] The reducer 13 connected to the output end of the motor 12 transmits kinetic energy to the coupling 7, and the coupling 7 transmits the kinetic energy to the first drive shaft 8. The first drive shaft 8 transmits the kinetic energy transmitted by the motor 12 to the auxiliary chain, the second sprocket 11 on the second drive shaft 15, and the first sprocket 10 on the first drive shaft 8 to the main chain 5, the first sprocket 10 on the second drive shaft 15, and the third sprocket 23 on the third drive shaft 22. The auxiliary chain and the main chain 5 located on both sides of the auxiliary chain rotate clockwise / counterclockwise, so that the veneer drying support frame on the production line obtains the kinetic power.

[0057] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
