Description
Technical Field
[0001] This utility model belongs to the technical field of binding equipment, specifically relating to a hot melt binding machine. Background Technology
[0002] The main structure of a hot melt binding machine includes a main body, a front baffle, and a rear baffle. The rear baffle is fixed to the main body, and the front baffle can move back and forth under the control of a handle. The front and rear baffles cooperate to form a clamping structure for accommodating documents to be bound. The main body is equipped with a heating component. In the prior art, patent CN210132893U discloses a hot melt binding machine in which a movable clamping plate is fixed to a heat dissipation plate, and a push-pull handle is provided on the heat dissipation plate. When the push-pull handle moves the movable clamping plate away from the fixed clamping plate, the heat dissipation plate gradually retracts into the interior of the binding machine body. The lower end of the push-pull handle is connected to a spring, which applies a pushing force towards the fixed baffle. This structure is used to push the movable baffle and the fixed baffle to clamp the documents to be bound.
[0003] Conventional hot melt binding machines have low heating efficiency and require 3-5 minutes of preheating before use. With improvements in heating elements and heat conduction structures, the heating efficiency of hot melt binding machines has increased, enabling rapid heating and preheating-free binding. Upgrading to a preheating-free hot melt binding machine requires the addition of electrical control components for temperature and time control. However, high-efficiency heating increases the operating temperature of these components, leading to reduced lifespan and decreased safety performance. Utility Model Content
[0004] For preheat-free hot melt binding machines, if the existing hot melt binding structure is used, the following problems will exist: On the one hand, the area where the moving plate overlaps with the main body shell is thick, and the electrical control component area cannot dissipate heat by transferring heat to the outer surface of the main body; on the other hand, the electrical control component area needs to exchange heat with the surrounding air when dissipating heat, and the more components and structures inside the hot melt binding machine, the worse its ventilation effect.
[0005] In view of this, the present invention aims to provide a heat dissipation efficiency structure for a hot melt binding machine that can be adapted to a preheating-free function.
[0006] This utility model is achieved through the following technical solution:
[0007] A hot melt binding machine, characterized in that it comprises:
[0008] The main body includes a main outer shell and an inner box, wherein the inner box contains a functional component area;
[0009] The inner box is also provided with a heating groove, and a front baffle and a rear baffle are provided on both sides of the heating groove. The front baffle and the rear baffle cooperate to form a clamping structure for the documents to be bound.
[0010] The rear baffle is disposed on the inner box; the front baffle is disposed on the movable plate, the movable plate having a working trajectory for moving back and forth along the clamping direction of the clamping structure; the movable plate at least constitutes part of the main body shell.
[0011] This invention improves heat dissipation efficiency by simplifying the main structure. In existing technology, the movable plate that drives the front baffle and the main shell are independent components, and there is overlap between them, which is not conducive to heat dissipation of functional components. In this solution, the movable plate is integrated into the main shell, and the two are combined into one, shortening the path for heat exchange between the functional component area and the external air. The optimized heat dissipation effect of the main body makes it suitable for preheating-free hot melt binding machines.
[0012] Preferably, the inner box body is provided with multiple sets of mating surfaces, and the movable plate is provided with multiple sets of friction surfaces. The multiple sets of friction surfaces cooperate with the mating surfaces to form an anti-slip structure that prevents the movable plate from moving on the working trajectory.
[0013] Furthermore, this solution utilizes the friction and mating surfaces between the movable plate and the inner box to counteract the pushing force on the front baffle when the documents to be bound spread out. When the front baffle is subjected to the pushing force of the documents spreading out, this force is transmitted to the movable plate, which must overcome the friction between the friction and mating surfaces to move. This solution saves space occupied by the clamping device, reduces the number of functional components inside the inner box, and improves heat dissipation.
[0014] Preferably, the movable plate is also connected to a shell side plate, which is disposed on the side of the inner box and constitutes part of the main shell.
[0015] After the outer shell side panel and the movable plate are connected as a whole, the overall weight of the movable plate increases, and the friction between the aforementioned friction surface and mating surface is also increased, making it less likely to be pushed by the force of the documents to be bound spreading out. When the heating tank needs to hold the documents to be bound, the front baffle is pulled away from the rear baffle, and the movable plate and the front baffle move horizontally at the same time. At this time, the outer shell side panel, which was originally attached to the side of the inner box, also moves away from the inner box as the movable plate moves horizontally, which is equivalent to the shell of the side area of the inner box becoming thinner, which is conducive to heat dissipation.
[0016] Preferably, the outer surface of the inner box is provided with space to accommodate the movable plate moving along the working trajectory.
[0017] In existing technologies, the movement trajectory of the movable plate is confined within the main casing, thus requiring the main casing to be enlarged to accommodate this trajectory. In this solution, the working trajectory of the movable plate is relatively independent of the inner box, thereby reducing the volume of the inner box and enabling the functional components inside the inner box to directly and efficiently exchange heat with the outside.
[0018] Preferably, the system also includes a movable side plate; the movable side plate is located in the heating groove and connected to the movable plate; the movable side plate and the rear baffle have a spacing adapted to the thickness of the document to be bound.
[0019] The movable side panel and the rear baffle form a clamping structure at the spine alignment area of the documents to be bound, fully pressing the pages together and improving binding quality. Furthermore, the movable side panel is located in the heating groove area, and its range of motion is limited by the range of the heating groove; the movable side panel is also connected to the movable plate, forming a structure that limits the range of motion of the movable plate, preventing the front baffle from being pushed away from the inner box when the documents to be bound unravel.
[0020] Preferably, the mating surface includes multiple sets of first mating surfaces, and the friction surface includes multiple sets of first friction surfaces. The first mating surfaces are disposed on the moving path of the first friction surfaces along the working trajectory, forming a limiting structure that restricts the moving distance of the movable plate on the working trajectory.
[0021] Since the movable plate in this solution has a working trajectory that is relatively independent of the inner box, the two are connected by a friction surface; in addition to providing anti-slip function, the friction surface in this solution also has a limiting function to prevent the movable plate from completely detaching from the inner box.
[0022] Preferably, the moving distance of the movable plate on the working trajectory is adapted to the accommodating width of the heating tank.
[0023] Preheat-free hot melt binding machines have high heating efficiency, therefore, it is necessary to isolate and protect the functional components in the inner box without affecting heat dissipation. This solution limits the movement distance of the movable plate. When the movable plate is at its maximum sliding position on the working trajectory, it can just fully expose the accommodating space in the heating groove without further exposing the functional component area in the inner box, thus preventing the components in the functional component area from being exposed and causing safety hazards.
[0024] Preferably, the movable plate is provided with multiple sets of heat dissipation windows.
[0025] In existing technologies, although heat dissipation vents are also located on a movable plate, they are concealed inside the host casing as the movable plate moves, thus losing their heat dissipation function. In this solution, since the movable plate is part of the host casing, the heat dissipation vents can provide heat dissipation channels to the components inside the host casing at any position, improving heat dissipation efficiency.
[0026] Preferably, the movable plate is provided with a handle for moving the movable plate.
[0027] Compared with existing technologies, the handle in this solution can be designed at any position on the movable plate, maximizing ergonomic design. The handle is connected to the movable plate, and the front baffle moves by moving the movable plate. The handle, movable plate, and front baffle are all located on the outside of the inner box, without occupying internal space, thus simplifying the internal structure of the inner box.
[0028] Preferably, the movable plate is provided with a disassembly groove, and the front baffle is detachably connected to the movable plate through the disassembly groove.
[0029] The front baffle in this solution is a detachable structure, and front baffles of different heights can be replaced according to different binding thicknesses to improve the clamping effect and binding quality.
[0030] This solution optimizes the structural relationship between the movable plate and the main unit's outer casing. The movable plate directly contacts the inner box and becomes part of the main unit's outer casing, shortening the heat dissipation path for functional components within the inner box. Furthermore, by utilizing the friction between the movable plate and the inner box, space occupied by the clamping device within the inner box is saved, further improving the main unit's heat dissipation efficiency. The proposed hot melt binding machine has excellent heat dissipation efficiency, is compatible with high-efficiency preheating-free hot melt binding machines, enhances device safety performance, and extends component lifespan.

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Example
[0042] This embodiment is a preheat-free hot melt binding machine.
[0043] To achieve preheating-free, instant-heat-up operation, hot melt binding machines typically use alloy resistance wire heating, with instantaneous heating temperatures reaching over 300 degrees Celsius. Therefore, this embodiment optimizes the structure of the hot melt binding machine to improve heat dissipation efficiency and prevent overheating of the electrical control components, thus avoiding safety hazards.
[0044] Please see Figure 2 The hot melt binding machine includes a lower main body and an upper baffle. The main body includes a main shell 2 and an inner box 1. The inner box 1 houses functional components such as a digital display, timer, and temperature control, which are integrated into the functional component area 110. A heating groove 8 is provided on the inner box 1, and a front baffle 6 and a rear baffle 7 are respectively provided on both sides of the heating groove 8. The front baffle 6 and the rear baffle 7 cooperate to form a clamping structure for the documents to be bound. To clamp documents of different thicknesses, the front baffle 6 and the rear baffle 7 have an adjustable spacing. The rear baffle 7 is fixed to the inner box 1, and the front baffle 6 is set on a movable plate 210. The movable plate 210 has a working trajectory that moves back and forth along the clamping direction of the clamping structure.
[0045] In the prior art, the movable plate 210 and the main shell 2 are independent components, and the movable plate 210 is located in the area between the main shell 2 and the inner box 1. The movable plate 210 and the main shell 2 overlap, and this area is relatively thick, preventing the electrical control components inside the main shell 2 from dissipating heat to the outside. In this solution, the movable plate 210 is located on top of the inner box 1 and constitutes part of the main shell 2. For the functional component area 110, the structure surrounding it changes from a double-layer structure consisting of the movable plate 210 and the main shell 2 to a single-layer structure consisting only of the main shell 2. This is equivalent to thinning the outer layer, improving heat dissipation efficiency, and meeting the working requirements of the preheating-free hot melt binding machine.
[0046] In the prior art, the movement trajectory of the movable plate 210 is contained within the space inside the main body shell 2. Therefore, the main body shell 2 needs to be enlarged to accommodate the movement trajectory of the movable plate 210. An excessively large volume is detrimental to the heat transfer from the internal components to the external surface for heat dissipation. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 In this embodiment, the movable plate 210 remains outside the inner box 1 as it moves along the working trajectory. Since the movable plate 210 is part of the main unit casing, the internal space of the inner box 1 is independent of the working trajectory of the movable plate 210, and only the functional components 120 need to be stored there. The reduced volume of the inner box 1 allows the functional components 120 inside the inner box 1 to directly and efficiently exchange heat with the outside.
[0047] Please see Figure 1 Multiple sets of heat dissipation windows 211 are provided on the side of the movable plate 210 near the heating groove 8. When the front baffle 6 and the rear baffle 7 are in close contact, the heat dissipation windows 211 are located above the heating groove 8; when the front baffle 6 and the rear baffle 7 maintain a certain distance, part of the heat dissipation windows 211 are located above the heating groove 8 and part are located above the inner box 1. In the prior art, although the heat dissipation windows 211 are also set on the movable plate 210, the heat dissipation windows 211 will be hidden inside the host casing as the movable plate 210 moves, losing their ventilation function. In this solution, since the movable plate 210 is a component of the host casing, the heat dissipation windows 211 can provide heat dissipation channels for the components inside the host casing at any moving position, improving heat dissipation efficiency.
[0048] Based on the contact between the movable plate 210 and the surface of the inner box 1, this solution further utilizes the friction between the movable plate 210 and the inner box 1 to counteract the pushing force on the front baffle 6 when the documents to be bound are spread out, saving the space occupied by the clamping device, reducing the number of functional components 120 inside the inner box 1, and improving the heat dissipation effect.
[0049] Please see Figure 3 The inner box 1 has multiple sets of mating surfaces 4, and the movable plate 210 has multiple sets of friction surfaces 3 on the side facing the inner box 1. These friction surfaces 3 and mating surfaces 4 cooperate to form an anti-slip structure that hinders the movement of the movable plate 210 along the working trajectory. Some friction surfaces and mating surfaces 4 are horizontally arranged, and the two provide mutual pressure through the weight of the movable plate 210. When the front baffle 6 is subjected to a pushing force from the unfolding of the documents to be bound, this force is transmitted to the movable plate 210, which needs to overcome the friction between the friction surfaces 3 and mating surfaces 4 to slide. In a preferred embodiment, the movable plate 210 is a metal part with a large self-weight, providing greater pressure and friction, resulting in good anti-slip performance. Other friction surfaces 3 and mating surfaces 4 are arranged laterally, and they provide mutual pressure through a tight fit.
[0050] Because the preheat-free hot melt binding machine has high heating efficiency, it is necessary to isolate and protect the functional components 120 in the inner box 1 without affecting heat dissipation. Considering that the movable plate 210 in this embodiment has a working trajectory relatively independent of the inner box 1, and the two are connected by the friction surface 3; in order to prevent the movable plate 210 from completely detaching from the inner box 1, the friction surface 3 in this solution not only provides an anti-slip function but also a limiting function to prevent the movable plate 210 from completely detaching from the inner box 1.
[0051] Please see Figure 3 The mating surface 4 includes multiple sets of first mating surfaces 410, and the friction surface 3 includes multiple sets of first friction surfaces 310. The first mating surfaces 410 are arranged in pairs on the moving path of the first friction surfaces 310 along the working trajectory, and are respectively located at the starting position and the ending position. When the first friction surface 310 moves with the movable plate 210, its moving range is limited by the distance between the two first mating surfaces 410. Furthermore, the distance between the two first mating surfaces 410 is equivalent to the accommodating width of the heating groove 8. When the accommodating width of the heating groove 8 is 40mm, the moving range of the movable plate 210 is also approximately 40mm; when the accommodating width of the heating groove 8 is 60mm, the moving range of the movable plate 210 is approximately 60mm. When the movable plate 210 is located at the maximum sliding position on the working trajectory, it can just completely expose the accommodating space in the heating groove 8 without further exposing the functional component area 110 in the inner box 1, preventing the components in the functional component area 110 from being exposed and causing safety hazards.
[0052] To match the shape of the inner box 1, the movable plate 210 is a square plate structure, with one side of the square facing the heating groove 8, while the other three sides face the outside of the inner box 1.
[0053] Please see Figure 3 A movable side plate 220 is connected to the side of the movable plate 210 facing the heating groove 8. The movable side plate 220 is located in the heating groove 8, and its distance from the rear baffle 7 is adapted to the thickness of the document to be bound. The movable side plate 220 and the rear baffle 7 cooperate to form a pressing structure at the spine position of the document to be bound, improving the binding quality. In addition, the movable side plate 220 is located in the area of the heating groove 8, and its range of motion is limited by the range of the heating groove 8. The movable side plate 220 forms a limiting structure for the range of motion of the movable plate 210, preventing the pressure when the document to be bound spreads out from pushing the front baffle 6 away from the inner box 1.
[0054] Please see Figure 1 , Figure 3The movable plate 210 has three outer shell side plates 230 connected to its three sides facing the outside of the inner box 1. The outer shell side plates 230 are located on the side of the inner box 1 and together with the movable plate 210 form the main outer shell 2 surrounding the inner box 1. The outer shell side plates 230 increase the overall weight of the movable plate 210, and increase the pressure and friction between the friction surface 3 and the mating surface 4. When the heating tank 8 needs to hold documents to be bound, the front baffle 6 is moved away from the rear baffle 7, and the movable plate 210 and the front baffle 6 move horizontally at the same time. At this time, the outer shell side plates 230, which were originally attached to the side of the inner box 1, also move away from the inner box 1 with the horizontal movement of the movable plate 210. This is equivalent to the shell of the lateral area of the inner box 1 becoming thinner, which is conducive to heat dissipation.
[0055] Please refer to the figure. The upper surface of the movable plate 210 is provided with a handle 240 for moving the movable plate 210. Compared with the prior art, the handle 240 in this solution can be designed at any position on the movable plate 210, maximizing ergonomics. The handle 240 is connected to the movable plate 210, and moves the front baffle 6 by moving the movable plate 210. The handle 240, the movable plate 210, and the front baffle 6 are all set on the outside of the inner box 1, without occupying the internal space of the inner box 1, thus simplifying the internal structure of the inner box 1.
[0056] Please see Figure 1 , Figure 3 The movable plate 210 has a disassembly groove 5 on the side near the movable side plate 220. A tab 610 adapted to the disassembly groove 5 is located below the front baffle 6. The tab 610 can be inserted into or removed from the disassembly groove 5, thereby enabling the installation or removal of the front baffle 6. Since the spring clamping structure is eliminated in this embodiment, the front baffle 6 is designed as a detachable structure to improve binding quality. Users can replace the front baffle 6 with different heights according to different binding thicknesses, improving the clamping effect.
